Reversible Valproate-Induced Subacute Encephalopathy Associated With a MT-ATP8 Variant in the Mitochondrial Genome
|
A 65-year old Caucasian woman with mild diabetes since 4 years, migraine and family history negative for neuromuscular diseases (Figure ), had a few episodes of loss of consciousness and fall, sometimes associated with urinary incontinence. A CT scan showed cerebral atrophy and an EEG slowing in the theta frequency range and left temporal spike activity. Based on the suspicion that those episodes could be epileptic, she was given a daily dose of 800 mg VPA. Within 3 months of treatment, the patient had a dramatic worsening of her clinical status, becoming bedridden and lethargic.\nOn admission clinical examination showed a short and stocky woman (height 138 cm, weight 70 kg) who appeared drowsy, but yet oriented in space and time. She could not walk nor stand unaided. Neurological examination showed vertical gaze palsy, intact function of the other cranial nerves, including normal fundus oculi, diffuse lower limb weakness (MRC score 3), and brisk tendon reflexes, without sensory, extrapyramidal and cerebellar involvement. Blood VPA was 61.9 mcg/ml (recommended therapeutic range 50–100), blood ammonia 45 μmol/l (n.v. 11–35), and serum lactate level at rest 8.6 mmol/l (n.v. < 2.2). There was also presence of organic aciduria with intermediates of Krebs cycle in the urine. Abdomen ultrasound imaging showed moderate fatty liver and no other relevant findings. The EEG showed slow activity in the lower alpha range (7.5–9/sec), mixed to theta and delta activity over the left fronto-temporal and occipital regions (Figure ). Brain MRI with MR-spectroscopy (MRS) showed diffuse cortico–subcortical atrophy, more marked in the fronto-temporal region. There were large confluent areas of white matter (WM) hyperintensity in T1 and T2-weighted images at level of the semioval centers and the periventricular region bilaterally, with extension in the capsula externa and sparing of the juxtacortical “U” fibers (Figures ). MRS showed a marked reduction of the NAA spectrum in the basal ganglia and in the WM, with a double spike at 1.3 ppm compatible with a peak of lactate (not shown).\nWe decided to titrate and then dismiss VPA therapy. During the following 2 weeks the patient had a significant improvement: she appeared alert and oriented, could walk unaided and came back able to perform daily activities independently. Neurological examination showed significant improvement of the lower limbs muscle strength (MRC score 4++). At a 12 month follow-up her clinical condition appeared unchanged. She underwent a muscle biopsy that evidenced some nonspecific age-related alterations as one necrotic fiber and a variability of morphology with some hypotrophic and angulated fibers and some evidence of mitochondrial dysfunction. In particular, 20% of the fibers were ragged-red at the Gomori trichrome stain with few cytochrome c oxidase negative (COX) fibers and slightly reduced activity of succinate dehydrogenase (SDH) (Figure ). The contemporary alteration of COX and SDH activity at histochemistry suggested an oxidative metabolism dysfunction. Subsequently, the spectrophotometric determination of respiratory chain enzyme activities in muscle homogenate showed multiple complex enzyme deficiencies. In particular, the activities of NADH-cytochrome c oxidoreductate (complexes I+III), succinate cytochrome c oxidoreductase (complexes II+III) and COX (complex IV) were 27, 20, and 23% of normal control values, respectively, when enzyme complexes were corrected for the activity of citrate synthase, a mitochondrial matrix enzyme used as an index of total mitochondrial mass (Table ).\nSequencing of the whole mitochondrial DNA in peripheral blood and skeletal muscle assigned the patient to mitochondrial haplogroup X2b and detected the homoplasmic m.8393C>T/p.Pro10Ser variant in MT-ATP8. Large scale mitochondrial deletions were appropriately ruled out. The p.Pro10Ser variant, of uncertain pathogenic significance () but already associated with VPA-induced toxic encephalopathy (1), was also homoplasmic in blood from six healthy relatives (Figure ). Western blot analyses in muscle homogenate from the patient did not reveal any reduction in the expression of respiratory chain complex subunits compared to controls (Supplementary Figure ) whereas ATP levels determined in cultured skin fibroblasts () showed reduced mitochondrial ATP synthesis and increased glycolytic ATP in the proposita, but not in her healthy daughter (III-02), compared to controls (Supplementary Figure ), suggesting an impaired ATP production machinery. To investigate if additional variants in nuclear DNA-encoded mitochondrial gene could contribute to the clinical phenotype, we analyzed in blood DNA from the proposita the coding regions of 1172 nuclear genes known to be associated with mitochondrial disorders (Mito-chip, see ) but we failed to detect rare predictably pathogenic variants of clinical significance. Supplementary Table lists rare (MAF < 0.01) variants of uncertain significance identified in the patient.

Effect of intravitreal dexamethasone on macular edema in von Hippel-Lindau disease assessed using swept-source optical coherence tomography: a case report
|
A 20-year-old Caucasian woman presented to our institution with decreased vision in the right eye (RE) with a 4-month evolution. The patient’s vital signs were within normal limits, and no abnormalities were noticed upon physical and neurological examination. Similarly, her past medical history was unremarkable. Her best corrected visual acuity (BCVA) was 50 ETDRS (Early Treatment Diabetic Retinopathy Study) letters in the RE and 84 ETDRS letters in the left eye. Her intraocular pressure (IOP) was normal in both eyes, and the result of her anterior segment examination was unremarkable. Upon ophthalmoscopic examination, a red-colored globular lesion of 3 disk diameters (DDs) with prominent feeder vessels was noticed in the superior temporal region of the retina in the RE (Fig. ). The fellow eye was normal on fundus examination, and no other lesions were found in the posterior pole or periphery. Optical coherence tomography (OCT) was carried out using the DRI OCT Triton™ SS-OCT device (Topcon Medical, Tokyo, Japan).\nA structural OCT B-scan of the RE showed a diffuse cystoid macular edema (central macular thickness of 450 μm) (Fig. ). The en face scan enabled assessment of the extent of the cystoid edema, which involved the posterior pole and expanded outside the vascular arcades (Fig. ).\nThe patient’s family history was collected, and it was discovered that the patient’s mother had died of pulmonary edema during pregnancy at the age of 40. A genetic test was carried out, which showed a variant in the VHL gene: c.335A>G(p.Y112C). In our patient, this variant was in the heterozygous state. On the basis of genetic findings and considering the presence of RHB, the diagnosis of VHL disease was made. A systemic study was conducted to search for other organs with lesions. Results of renal ultrasonography and magnetic resonance imaging of the brain were both negative for visceral lesions.\nThe patient received an intravitreal injection of ranibizumab and was then followed every month. Forty days after the injection, an OCT B-scan and an OCT en face scan revealed a reduction in RE macular edema (Fig. ). The patient’s BCVA was 50 ETDRS letters in the RE. Considering the persistence of cystic spaces, an intravitreal injection of slow-release dexamethasone was considered to reduce macular edema in preparation for cryotherapy. At 60 days following ranibizumab administration, a slow-release intravitreal dexamethasone implant (IDI) was injected. A structural OCT B-scan performed 1 week after IDI showed the almost complete absence of cystic spaces in the subfoveal and perifoveal areas (Fig. b′) with complete restoration of the retinal profile (Fig. a′). Inconsistent with the improvement in retinal morphology, the patient complained of visual impairment and recurring headache. BCVA was found to be 42 ETDRS letters in the RE. No changes IOP values were observed during the follow-up examinations.\nTwenty days after IDI, the patient’s RHB was treated with a combination of laser photocoagulation and a triple freeze-thaw technique of transconjunctival cryotherapy. Although the patient’s retinal profile seemed to have been restored, OCT images obtained 20 days after cryotherapy was performed (Fig. ) showed increased exudation causing a massive and wide serous retinal detachment. The patient was then followed every month for 6 months, and, considering the persistence of the exudative retinal detachment and having ruled out the presence of a retinal break, she is currently under evaluation for pars plana vitrectomy (possibly associated with lens extraction and/or scleral buckling) and endovitreal tumor treatment.

Rare Shewanella spp. associated with pulmonary and bloodstream infections of cancer patients, China: a case report
|
A esophageal cancer patient who was diagnosed as S. haliotis pulmonary inflammation.\nA 68-year-old male patient was admitted to people’s hospital of Liaocheng city, China, on July 24, 2016, because of “hematemesis for 4 hours”. He had been diagnosed with the operation of esophageal cancer for more than 2 years. His admitted physical examinations were body temperature of 36.3 °C, pulse rate 92 beats/min, breathing of 22 times/min and blood pressure 135/80 mmHg. Nonpalpable enlargement of bilateral neck and supraclavicular lymph nodes, trachea in the middle, pectoral symmetry, visible scars at right chest, clear percussion sound at double lung, auscultation of coarse breath sound, no dry and wet rales, regular rhythm, percussion no pain of the kidney area, negative for shifting dullness and bowel sounds of 3 times/min. His admission diagnosis was esophageal cancer after operation and hypertension. On admission, the auxiliary examinations were performed to determine the source of hematemesis. The painless gastroscopy was carried out, but no obvious abnormalities was observed. The painless bronchoscopic examination revealed posterior basal segment of left lower lobe hemorrhage. Brushing pathology indicated no obvious tumor cells. Thoracic and abdominal enhanced computed tomography scan showed that he had esophageal surgery, bronchitis and emphysema, middle lobe of right lung nodules, right upper lobe and left lower lobe interstitial lesions and the lower lobe of the left lung inflammation. He was given medicine (3 g of cefoperazone/sulbactam was administrated twice a day for 6 days) and therapy of anticancer, anti-inflammatory, rehydration and hemostasis. After six days’ treatment, his symptoms improved and the patient was discharged from the hospital.\nThe bronchoalveolar lavage fluid (BALF) was collected when he received painless bronchoscopic examination and the cell number was over 104 cfu/ml. Sample was streak-inoculated on blood agar medium for bacterial culture. Strains of different phenotypic features at blood plates were isolated and identified as S. algae, Escherichia coli and Klebsiella pneumoniae by VITEK 2 system using the ID-GN card (boiMérieux). Since only two Shewanella species, S. putrefaciens and S. algae, were registered in the database of VITEK 2 system, the 16S rRNA gene sequence was amplified by a PCR described previously []. The PCR product was sequenced and the nucleotide sequence had been deposited at GenBank, under the accession number of MF589233. BLAST analysis of 16S rRNA gene sequence at GenBank showed a similarity of 99.0% with type strain of S. haliotis DW01 (accession numbers NR_117770.1). Further phylogenetic analysis with all type sequences of Shewanella species available in the GenBank database, confirmed the strain was identified as species of S. haliotis (LC2016–1 in Fig. ).\nTo further confirm the bacterial community composition and richness of the BALF, sample was subjected to the 16S rRNA amplicon sequencing [, ]. The result indicated the bacterial community composition included genera of Shewanella (88.34%), Escherichia (11.11%) and Streptococcus (0.38%), et al., whereas the majority of genus was Shewanella.\nAntibiotic susceptibility testing was performed by microdilution method on Mueller-Hinton broth. The strain was susceptible to piperacillin/tazobactam (minimal inhibitory concentration, MIC: 8 μg/ml), ceftazidime (1 μg/ml), cefepime (1 μg/ml), amikacin (2 μg/ml), gentamicin (1 μg/ml), imipenem (4 μg/ml), meropenem (4 μg/ml), but was resistant to ciprofloxacin (8 μg/ml) and levofloxacin (8 μg/ml).

Rare Shewanella spp. associated with pulmonary and bloodstream infections of cancer patients, China: a case report
|
A gastric cancer patient who was diagnosed as S. algae bacteremia.\nA 56-year-old man was admitted to people’s hospital of Liaocheng city, China, on 6, Oct. 2016, because of “discomfort of upper abdominal pain for 1 month”. His admitted physical examination included body temperature of 36.1 degrees, pulse rate of 72 beats/min, breathing 18 times/min and blood pressure 140/90 mmHg. Detection of nonpalpable enlargement of bilateral neck and supraclavicular lymph nodes, flat abdomen, no gastrointestinal or peristaltic waves were observed. Soft abdominal muscles, mild tenderness in the upper abdomen and no obvious rebound pain were reported. His liver and spleen did not touch under the rib and no palpable mass was discovered. Negative for shifting dullness, normal bowel sounds and no abnormal of rectal examination were detected. The gastroscope suggested visible ulcer lesions at the cardiac involving gastric fundus and gastric body. The pathological results indicated adenocarcinoma. His admission diagnoses were gastric cancer and hypertension.\nOn admission, the auxiliary examination were carried out on Oct. 9, 2016. Laparoscopy indicated he was in the late stage tumors without radical resection. He then received intravenous and intraperitoneal chemotherapy, followed by severe bone marrow suppression with blood cells and platelets significantly lower than normal. He was given further treatment of anti infection, nutritional support, rehydration, stimulating granulopoiesis and symptomatic treatment. On Oct. 26, 2016, patients had shortness of breath, heart rate and other symptoms with lung breath sounds rough, and no rales, limbs cold. He was considered the existence of septic shock. He was given non-invasive mechanical ventilation and fluid expansion, colloid, blood transfusion products, anti infection (1 g of imipenem was administrated every 8 h for 7 days), maintain circulation, acid suppression, liver protection, nutritional support, maintenance of water and electrolyte acid-base balance, monitoring blood pressure, heart rate, respiratory function, hour urine volume and bleeding. Patient had severe infection, and the presence of multiple organ dysfunction syndrome (breathing, circulation, gastrointestinal, blood and kidney). Patient and his family members required automatic discharge for hospice care. His discharge diagnoses were multiple organ dysfunction syndrome (respiratory, circulatory, gastrointestinal, blood and kidney), gastric cancer and hypertension.\nAfter appearing septic shock, his blood culture was sampled to separate the bacteria. The microbial growth was detected in both anaerobic and aerobic bottles and the positive reported time were 8.1 and 11.9 h, respectively. Both bottles yielded an uniform Gram-negative bacillus. After 24 h incubation, haemolytic, oxidase-positive yellow colonies grew on blood agar. The strain was identified as S. putrefaciens by VITEK 2 system using the ID-GN card (boiMérieux). The 16S rRNA gene sequence of the strain had been deposited at GenBank (accession number: MF589234). BLAST analysis at GenBank showed a similarity of 100.0% with S. upenei strain VITVAGJ (accession numbers KP090164.1). Further phylogenetic analysis with all type sequences of Shewanella species available in the GenBank database, confirmed the strain belonged to species of S. upenei (LC2016–5 in Fig. ). On the day of blood sampling, his peritoneal drainage fluid was also collected and cultured using the same identification methods, and the results of bacterial identification and drug sensitivity were consistent with that of blood.\nAntibiotic susceptibility testing was performed by microdilution method on Mueller-Hinton broth. The strain was susceptible to aztreonam (1 μg/ml), ceftazidime (1 μg/ml), cefepime (1 μg/ml), amikacin (2 μg/ml), gentamicin (1 μg/ml) and levofloxacin (1 μg/ml), but was intermediate to imipenem (8 μg/ml), piperacillin/tazobactam (64 μg/ml) and ciprofloxacin (2 μg/ml).

Relapse of chronic melioidosis in a paediatric cystic fibrosis patient: first case report from Malaysia
|
A 14-year-old Chinese Malaysian boy presented to University Malaya Medical Centre, Kuala Lumpur in September 2013 with history of recurrent pneumonia, poor growth and steatorrhoea since childhood. He had finger clubbing and bronchiectasis. Later, he was diagnosed with CF and Pseudomonas aeruginosa was isolated from his sputum. He received 3 weeks of intravenous ceftazidime (50 mg/kg/dose, QDS) and gentamicin (5 mg/kg/dose, OD). He was discharged with azithromycin (5 mg/kg EOD), nebulised gentamicin (80 mg BD) amongst other CF-related medications. In November 2013, he was readmitted with a pulmonary exacerbation and his sputum sample grew methicillin-resistant Staphylococcus aureus (MRSA) and he received intravenous vancomycin, oral rifampicin (300 mg BD) and sodium fusidate (500 mg TDS) with significant clinical improvement. During a follow-up visit in December 2013, he had a productive cough but was apyrexic. He was empirically treated with oral ciprofloxacin (750 mg BD) and the sputum sample later isolated B.pseudomallei. As he clinically improved, the treatment regimen remained unchanged. Subsequently, the repeat sputum samples were negative for B.pseudomallei and he continued to remain active with good exercise tolerance and relatively stable lung function. It is noteworthy that he had been residing in an urban area of non-endemicity for melioidosis and there were no other known risk factors identified.\nIn August 2014, he was admitted with another pulmonary exacerbation and his cultured sputum grew B.pseudomallei and Pseudomonas spp. His chest radiograph showed diffused interstitial changes with bronchiectasis throughout both lungs with minimal pleural effusions. He received 2 weeks of intravenous ceftazidime (2 g; 6hourly) and amikacin (720 mg; 15 mg/kg/OD). Upon completion of antibiotics, he remained afebrile and the chest auscultatory findings improved. He was discharged with 6 months of oral doxycycline, and co-trimoxazole to treat the B.pseudomallei and 3 months of nebulized amikacin for chronic P.aeruginosa. He still continued on his alternate day of azithromycin (250 mg).\nA detailed travel history revealed that in June 2014, he visited recreational parks in Sabah, Malaysia. During the visit, he went jungle trekking, snorkeling and dipped in a hot-water spring. It is noteworthy that melioidosis is endemic in Sabah, one of the two East Malaysian states on the island of Borneo, where B.pseudomallei prominently occurs in soil and water. Later then, he was admitted 3 monthly for antibiotic tuning and his sputum culture had no specific bacterial growth.\nIn August 2015, there was a decline in his lung function tests with deterioriorating cough. A bronchoscopy was performed and Burkholderia cepacia was isolated from his bronchoalveoloar lavage specimen, while acid-fast bacillus (AFB) smear was weakly positive. Initially, the patient was treated with intravenous imipenem and ceftazidime for 3 weeks but had recurrence of fever. However, the sputum AFB smears remained positive although the suspected nontuberculous mycobacterium could not be isolated despite various culturing techniques. Therefore, the antibiotics were changed to intravenous meropenem, doxycycline, amikacin and oral clarithromycin to treat both the B.cepacia and the suspected nontuberculous mycobacterium.\nUpon discharge, he had been continuing with amoxicillin-clavulanate and doxycycline for 6 months, which helped with weight gain and secretion reduction. Repeat AFB smear remained negative for the subsequent 5 months. However, in January 2016, further decline in his lung function was observed with worsening respiratory symptoms. A chest computed tomography showed worsening bronchiectasis, tree in bud appearance in the lung peripheries, patchy consolidation and several enlarged lymph nodes at the right paratracheal region (Fig. ). His sputum sample grew P.aeruginosa and was also strongly positive for AFB. Intravenous meropenem and ceftazidime (for P.aeruginosa) and combination therapy of rifampicin, ethambutol, azithromycin and nebulized amikacin (for nontuberculous mycobacterium) was started. He improved clinically and was discharged with the above oral medications for 6 months.\nB.pseudomallei was isolated once again in April 2016 and he was treated with intravenous amoxicillin-clavulanate and ceftazidime for 3 weeks. He was then discharged with 6 months of oral amoxicillin-clavulanate. However, in May 2016, his antibiotics were changed to levofloxacin (750 mg) and clarithromycin (500 mg). Following that, for the next 8 months, his sputum sample continued to grow B.pseudomallei but was negative for AFB. Despite many admissions for intravenous antibiotics against B.pseudomallei, the patient passed away from end stage respiratory failure in February 2017. Bacteriological reports were reviewed, and over the 3 years, the patient had several infective exacerbations and his sputum samples grew Gram-negative organisms that were later identified to be B.pseudomallei, Pseudomonas spp., P.aeruginosa, or B.cepacia (Table ).\nAll the isolates were found to have different susceptibility patterns (resistant to co-trimoxazole; intermediate to doxycycline and susceptible to all other antibiotics). The B.pseudomallei isolated in 2013, 2014 and 2016 (UMC083, UMC 082 and UMC114, respectively), were also further confirmed as B.pseudomallei using API 20NE (Biomerieux, France), Ashdown agar and also an in-house polymerase chain reaction (PCR) using specific primers []. However, we were not able to obtain the B.pseudomallei isolated in 2017.\nThe isolates were characterized by multilocus sequence typing (MLST), a method of molecular subtyping that compares sequences of seven housekeeping genes [], and repetitive-element PCR (rep-PCR). It appeared that these isolates were of two different sequence type (ST); ST51 (UMC083 and UMC114), which is a common ST found widely in Malaysia, Thailand, Singapore, Hong Kong and China, and ST1644, (UMC082) a new ST. The STs were deposited in the B.pseudomallei MLST database ().

Hypercalcemia-induced acute kidney injury in a Caucasian female due to radiographically silent systemic sarcoidosis
|
We report a 77-year-old Caucasian female who had presented to nephrology clinic with a history of multiple sclerosis in remission who was noted to have progressive weakness for 2 months prior to presentation. Suspicion for a multiple sclerosis flare was low since her electrolytes were grossly abnormal with a serum calcium of 13.7 mg/dL and a serum creatinine of 2 mg/dL on June 23, 2017, increased from baseline of 8 – 9 mg/dL (calcium) and 0.9 – 1.1 mg/dL (creatinine). Ionized calcium was measured at 1.54 mmol/L (reference range 1.09 – 1.29 mmol/L), confirming the hypercalcemia noted on chemistry. Patient had initially been taking cholecalciferol 2,000 units PO daily for osteoporosis prophylaxis which were stopped, but this failed to improve the serum calcium. Parathyroid hormone (PTH) was appropriately suppressed at low normal 18 – 21 pg/mL (reference range 11 – 51 pg/mL), PTH-related peptide was in range at 17 pg/mL (reference range 14 – 27 pg/mL) which was not consistent with hypercalcemia of malignancy. The patient had normal sodium and alkaline phosphatase values. Urinalysis showed only 1+ proteinuria and was otherwise normal, and the kidney ultrasound demonstrated normal kidney structure. 25-hydroxy vitamin D level was 28 – 37 ng/mL (reference range: 20 – 50 ng/mL), but 1,25-dihydroxy vitamin D levels remained elevated despite stopping any supplements and remained elevated for nearly 2 months. 1,25-dihydroxy vitamin D peak level was 158 pg/mL (reference range: 19.9 – 79.3 pg/mL) and remained elevated between 100 and 113 pg/mL despite stopping vitamin D supplements. Urine protein electrophoresis and serum electrophoresis were negative or an M-spike, immunofixation was only positive in serum with IgG-κ monoclonal being found. κ- and λ-light chains were only slightly skewed towards IgG-κ > IgG-λ with a ratio of 2.32, ruling out monoclonal gammopathy as the etiology for the hypercalcemia.\nThe patient’s hypercalcemia continued to cause acute kidney injury, her calcium reached 12.6 mg/dL, she was hospitalized where she was given IV fluids, furosemide, and pamidronate. A high resolution CT scan did not show any lymphadenopathy or pulmonary pathology (), and angiotensin-converting enzyme levels were elevated at 100 U/L and 102 U/L for 2 draws. After the aforementioned treatment, her serum calcium decreased to 10.5 mg/dL.\nWhen her serum calcium increased to 11.8 mg/dL, she was given denosumab 120 mg formulation in the interim leading to the return of serum calcium to 10.5 mg/dL. Since infectious causes of granulomatous diseases, such as tuberculosis and fungal infections, were in the differential diagnosis corticosteroids were not given empirically. While the high level of angiotensin-converting enzyme suggested possible sarcoidosis, we considered the low specificity of the test to demand more definitive tissue diagnosis could be obtained. Thus, corticosteroids were deferred until definite diagnosis, and denosumab was prescribed in the interim to control hypercalcemia.\nSee for graphs of serum calcium, PTH, 25-hydroxy vitamin D, 1,25-dihydroxy vitamin D, angiotensin-converting enzyme level, and serum creatinine levels. Mycobacterial serologies, coccidiomycosis, and other fungal serologies were negative as well.\nIt was during this time that granulomatous disease, specifically sarcoidosis was suspected. She underwent PET scan with findings of upper lobe predominant peri-bronchial wall thickening, diffuse lymphadenopathy and flourodeoxyglucose (FDG) uptake throughout pulmonary parenchyma. This was suggestive of a granulomatous process such as sarcoidosis. No other focus of FDG uptake in a pattern that suggests malignancy was found, and no splenic involvement was seen. See for PET scan image and findings.\nWhen the patient’s creatinine increased to 2.58 mg/dL with a serum calcium of 11 mg/dL, the patient was admitted for definitive diagnostic procedures. Bone marrow biopsy and a transbronchial lymph node biopsy were obtained. The patient’s serum calcium and serum creatinine normalized with hydration and subcutaneous calcitonin injection. Biopsy results showed diffuse non-necrotizing/non-caseating granulomata in lung and bone marrow confirming diagnosis of systemic sarcoidosis. Cultures from lung biopsy were negative for mycobacteria, fungal elements, or bacteria. The sarcoidosis staging was rated at stage 0 according to lung imaging, but with a high enough burden of disease to cause significant hypercalcemia. Please see for details of biopsy findings and bone marrow biopsy results. The patient started 20 mg of prednisone after diagnosis with improvement of hypercalcemia down to serum calcium of 10.2 mg/dL. She is receiving 3 times weekly hydration with IV normal saline to help prevent dehydration which helped decrease serum creatinine to 1.58 mg/dL. The patient was not on TNFi (tumor necrosis factor) to suggest secondary sarcoidosis. Her multiple sclerosis was stable as well. She was started on plaquenil for maintenance treatment of the diagnosed sarcoidosis.

Successful treatment of endogenous endophthalmitis with extensive subretinal abscess: a case report
|
A 61-year-old man presented with pain, redness, floaters and decreased vision in his right eye for two days. It was diagnosed as anterior uveitis at a local clinic and treated with prednisolone acetate eye drops combined with intravenous drip of dexamethasone and cephalosporin for seven days. Two weeks later, the patient’s visual acuity decreased to light perception, so he was referred to us eighteen days after his initial onset of symptoms. The patient had no previous history of systemic diseases or infectious diseases, no trauma or surgery before, no chronic medication used. He had a history of heavy drinking and chronic peptic discomfort, and he had been diagnosed suffering from peptic ulcer by agastroscopytwo weeks prior to the onset of symptoms. He had loss of appetite after abstinence from alcohol and reduced 15 kg of weight during the previous one month.\nAt presentation, vision was light perception in the right eye and 6/6 in the left. The slit-lamp examination of the right eye revealed mild injection, anterior chamber cells of 2+ with a hypopyon of 1.4 mm, pupillary hypopyon, posterior iris synechia, and fibrinous exudates covering the anterior lens capsule (Fig. ). Fundus of the right eye was invisible due to the vitreous opacity and the left eye was normal. Intraocular pressure was normal in both the eyes. The color ultrasound examination revealed dense vitreous opacities and a avascular homogeneous hyperechoic mass (Fig. ).\nThe vital parameters were in normal range, with the blood pressure of 132/80 mmHg, pulse 76/min and a temperature of 36.7° Celsius. Physical examination did not show any abnormalities. Systemic investigations including blood routine examination, liver and renal function tests, computed tomography scan of the lung and abdominal were all unremarkable. Serologic tests that included human immunodeficiency virus antibody, antibodies for toxoplasma, varicella zoster virus, herpes simplex virus and the treponemal antibody-absorption test yielded negative results. Laboratory result for fasting blood glucose was 9.07 mmol/l (normal range: 3.88~ 6.1). The patient was diagnosed as diabetes mellitus after many blood glucose tests and was treated with Metformin. No specific site of systemic infection was found. Presumptive diagnosis of right EE was made, but intraocular lymphoma could not be ruled out.\nVitreous and anterior chamber taps of the right eye were performed, aqueous and vitreous aspirations were sent for cultures and histopathology examination. The patient was treated with intravitreal injection of vancomycin 1 mg/0.1 ml and ceftazidime 2 mg/0.1 ml, topical levofloxacin 0.5% and prednisolone 1% acetate eye drops six times a day, atropine 1%ointment at night in the right eye, concurrent with intravenous drip of cefoperazone.\nThree days after the intravitreal injection, the results of vitreous samples cultures and histopathology examination were all negative. The anterior chamber inflammation improved, and fundus of the right eye was still invisible. B-scan ultrasound showed increased vitreous debris and extensive thickening of the retina and choroid layer. Therefore, a pars plana vitrectomy (PPV) combined with phacoemulsification was performed. After a complete vitrectomy, a white elevated fluffy mass with the overlying retinal whitening and necrosis was revealed in superior periphery (Fig. ). In addition to this, extensive retinal hemorrhages and five adjacent subretinal whitish masses with exudative retinal detachment were observed in the posterior pole and inferior quadrants which were suggestive of extensive subretinal abscess with intense overlying retinal inflammation (Fig. ). Intraoperatively, we carefully cleared the white fluffy mass in superior and peripheral vitreous without retinal break formation. A white fluffy cotton-like substance was excised from the superior mass (Fig. ) and finally left a 4-disc diameter retinal defect (Fig. ). The vitreous and cotton-like substance were sent for culture, histopathology examination, and polymerase chain reaction (PCR) testing. Retinotomy and aspiration of extensive subretinal abscess in the posterior pole and inferior were not performed. Laser photocoagulation around the retinal defect site and gas or oil intraocular tamponade were not performed either. No intravitreal or intravenous antibiotics were used for we were not sure if the infection arose from fungal, bacterial, mycobacterial or a different aetiology. Post-operative administration remained topical levofloxacin 0.5%, prednisolone 1% acetate eye drops six times a day and atropine 1% ointment once a day.\nOn post-operative day 1, slit-lamp examination showed anterior segment moderate inflammatory reaction and no posterior segment view because of vitreous opacities. B-scan ultrasound of the right eye showed vitreous opacities and an extensive retinal detachment with sub-retinal exudates (Fig. ). On post-operative day 4, the inflammatory reaction subsided significantly and the media started clearing. A blurry fundus was observed. B-scan ultrasound showed slight vitreous opacities and shallow retinal detachment (Fig. ). The result of vitreous samples PCR was positive for Klebsiella pneumonia (KP). The results of cultures and histopathological examination were again negative. Clinical examination along with PCR testing confirmed the diagnosis of EE caused by KP. An intravitreal injection of ceftazidime 2 mg/0.1 ml on the right eye was performed. On post-operative day 9, the anterior chamber and vitreous cavity were clear, the retina reattached with lots of yellowish subretinal precipitates and a scar at the superior region (Fig. ). B-scan ultrasound showed retina reattached except localized shallow retinal detachment (Fig. ). Corrected visual acuity improved to hand motions and intraocular pressure was normal. Intravitreal injection of ceftazidime 2 mg/0.1 ml was repeated in the right eye. The patient was discharged for follow-up as an outpatient with levofloxacin 0.5% and prednisolone 1% acetate eye drops administered topically for one week. He was in a stable condition at subsequent visit two months later. Fundus and B-scan ultrasound examination revealed the retina remained attached with some yellowish subretinal precipitates, a large fibrotic scar superiorly, an epiretinal membrane presented in the posterior pole (Fig. ). At eight months, his eye remained quiescent with a corrected visual acuity of hand motions.

Rheumatoid meningitis presenting with a stroke-like attack treated with recombinant tissue plasminogen activator: a case presentation
|
A 55-year-old woman suddenly became aware of speech difficulty and left arm numbness at 11:00 pm while talking on the telephone with her daughter. She was taken to our hospital by ambulance. She was diagnosed with RA 6 months earlier, and she had been treated with methotrexate at a dose of 10 mg daily. She had a history of herpes simplex encephalitis from 30 years earlier. Her blood pressure was 155/80 mmHg, pulse rate was 80/min and regular, and temperature was 36.8 °C. ECG was normal. Her Glasgow coma scale was E4 V4 M6, and neurological examination demonstrated dysarthria, left hemiparesis, left-sided sensory impairment, and left unilateral spatial neglect. The National Institutes of Health Stroke Scale (NIHSS) score was 5. Head computed tomography (CT) showed no obvious lesions except effacement of the cortical sulci in the right parietal lobe, and the Alberta Stroke Program Early CT Score (ASPECTS), a 10-point quantitative topographic CT scan score, was 8. No arterial occlusion or stenosis was seen on CT angiography (Fig. ). Blood tests showed a platelet count of 274 × 103/μl, prothrombin time International Normalized Ratio (PT-INR) of 1.07, and activated partial thromboplastin time (APTT) of 25.6 s (APTT-control 31.0 s). She was diagnosed with acute embolic stroke in the right parietal lobe, and there was no contraindication to intravenous thrombolytic therapy. At 4 h 6 min after onset, intravenous administration of rt-PA was started in accordance with the Japanese guideline (alteplase, 0.6 mg/kg) [, ], with an intravenous drip infusion of 30 mg of edaravone, a free radical scavenger, over a period of 30 min. Head magnetic resonance imaging (MRI) was performed at 1 h, 30 min after starting the thrombolytic therapy (Fig. ). Diffusion-weighted imaging (DWI) demonstrated a linear high-intensity lesion in the right temporoparietal cortex. The lesion was demonstrated to be a hypodense linear lesion on the apparent diffusion coefficient (ADC) map image. This cortical lesion was seen as a high-intensity lesion on fluid-attenuated inversion recovery (FLAIR) imaging. These MRI findings were not compatible with acute ischemic stroke. Her neurological deficits improved rapidly (NIHSS score: 5 on admission, 1 at 24 h after thrombolytic therapy).\nContrast-enhanced head MRI performed on hospital day 3 found that the high signals on DWI had disappeared. However, the FLAIR image showed ribbon-like high signals in the cerebral cortex, and no contrast effect was observed (Fig. ). In subsequent additional tests, rheumatoid factor (RF) was 85 IU/L and anti-cyclic citrullinated peptide (CCP) antibody was elevated at 223.7 U/mL, while myeloperoxidase-anti-neutrophil cytoplasmic antibodies (MPO-ANCA) and proteinase-3-anti-neutrophil cytoplasmic antibodies (PR3-ANCA) were negative. Lumbar puncture showed a cell count of 68/μL (monocytes 14, polynuclear cells 54), protein 40 mg/dL, and glucose 52 mg/dL. Single photon emission computed tomography (SPECT) performed on day 6 showed decreased accumulation in the right temporoparietal region. Spinal fluid testing performed on day 10 showed an elevated interleukin-6 (IL-6) of 271 pg/mL, but anti-CCP antibody was normal at 3.7 U/mL. Because of the elevated cerebrospinal fluid cell count and the patient’s history of herpes encephalitis, she was temporarily treated with a continuous intravenous infusion of acyclovir 1500 mg/day until the polymerase chain reaction test was confirmed to be negative. The patient was finally diagnosed with RMSA. On day 16, continuous infusion of methylprednisolone 1000 mg daily was started for 3 days, and it was repeated on day 28. Her symptoms then gradually resolved, and the high signal on the FLAIR image also disappeared. The patient was discharged on day 44 with only a slight attention deficit on neurological examination.

Primary histiocytic sarcoma of the central nervous system: a case report with platelet derived growth factor receptor mutation and PD-L1/PD-L2 expression and literature review
|
Our patient was a 47 year old female with a history of ulcerative colitis, Sjogren’s syndrome, migraines, and fibromyalgia who presented with a 6 month history of left lower extremity paresthesia followed by a 2 month history of progressive headaches, imbalance, ataxia, nausea, vomiting, and diplopia. Neurologic examination revealed severe gait ataxia requiring assistance to stand or walk and nystagmus with lateral gaze. MRI revealed a 3.0 cm heterogeneously enhancing mixed cystic and solid mass centered upon the cerebellar vermis with mild surrounding vasogenic edema and abnormal thickened enhancement of the bilateral vestibular nerves, left facial nerve, and right trigeminal nerve (Fig. ).\nThe patient was promptly started on steroids, admitted to the hospital, and underwent a midline suboccipital craniotomy for debulking of the large intracerebellar tumor. Upon entering the cystic cavity, grossly purulent material without hemorrhage was noted. Gram stain and cultures were negative for infection. A subtotal resection was achieved and final pathology rendered the diagnosis of primary CNS histiocytic sarcoma (see Fig. ). The H&E section (Fig. ) revealed sheets of large neoplastic cells with marked cytological atypia, brisk mitosis with occasional multilobated nuclei, and focal necrosis. Extensive immunohistochemical studies (Fig. ) showed the neoplastic cells positive for CD163, CD68, CD45, and Vimentin; negative for CD20, CD3, CD30, s-100, CD1a, CD21, CD23, pancytokeratin, MPO, CD61, CD123, GFAP, and BRAF. Further immunostains for PD-L1 with two different antibody clones (22C3 and 28–8) were also performed and showed more than 50% of the tumor cells were positive with membrane stain (Fig. ).\nPost-operative MRI showed a midline posterior occipital craniotomy with subtotal resection of tumor and continued bilateral-enhancement along multiple cranial nerves, concerning for leptomeningeal spread (Fig. ).\nA staging PET scan was performed two weeks following surgery suggesting diffuse leptomeningeal spread. A complete spinal MRI confirmed diffuse leptomeningeal spread in the lower thoracic and lumbar spine as well as cauda equina involvement. Due to the convincing evidence on MRI, a CSF analysis was deferred. Standard lab work was within limits, including LDH (Fig. ).\nThree weeks following surgery, due to progressive lower back pain, she initiated radiation therapy including whole brain radiotherapy (30.6 Gy in 17 fractions) followed by a posterior fossa boost (5.4 Gy in 3 fractions) and a gross tumor boost (9 Gy in 5 fractions), for a total dose of 45 Gy in 25 fractions to gross disease with simultaneous radiation therapy to the lower thoracic and lumbar spine, receiving 40 Gy in 20 fractions, encompassing the areas of leptomeningeal disease in the spine and cauda equina. Full craniospinal radiotherapy was not performed to limit profound cytopenias that may have prevented further cytotoxic chemotherapy.\nInterval follow up MRI showed a partial response with persistent posterior fossa disease but near complete resolution of previous leptomeningeal enhancement. Our plan was to initiate chemotherapy with a primary CNS lymphoma regimen with high CNS penetrating therapeutic agents including high-dose methotrexate, high-dose Ara-C, and thiotepa followed by high-dose chemotherapy with BCNU and thiotepa rescued by autologous stem cell transplantation. The patient was started on high dose intravenous methotrexate (HD-MTX) therapy, but received only one cycle secondary to patient intolerance.\nA CT of the chest approximately two weeks after initiation of HD-MTX therapy for left sided rib pain showed new pulmonary nodules and a left sided pleural effusion, suspicious for metastatic disease. Thoracentesis revealed findings consistent with a malignant pleural effusion. The patient was initiated on cladribine (Leustatin).\nWithin two weeks after the completion of this infusion, the patient developed headaches, somnolence, fever, and nuchal rigidity. Malignant meningitis was suspected and the patient was started on IV antibiotics. Lumbar puncture was recommended but the patient declined. Her mental status significantly improved following antibiotic treatment. Brain MRI showed continued response of the cerebellar residual disease and no new intra-cranial lesions, but an MRI of the cervical spine showed new lesions consistent with metastatic disease in the untreated cervical spinal cord and thoracic vertebrae, including intramedullary involvement. She underwent further radiation therapy targeting C4-C6 and T1-T7 (20 Gy in 5 fractions). The patient rapidly showed improvement in symptoms.\nGenomic sequencing of her tumor showed a novel mutation in the platelet-derived growth factor receptor A (p.V608I) and therefore, she was started on Dasatinib, a tyrosine kinase inhibitor (TKI) with known CNS penetration []. Unfortunately, this medication was poorly tolerated because of nausea, diarrhea, and acute pancreatitis so it was discontinued after one week.\nThe patient was readmitted to the hospital for continued decline in functional status, weakness, and failure to thrive. CT images of the chest, abdomen, and pelvis showed progressive bilateral pulmonary nodules. An MRI of the spine showed persistent but significantly improved leptomeningeal enhancement. Due to progression of symptoms, worsening systemic disease despite control of CNS disease, and limited systemic options available, the patient chose to enroll in hospice. The patient expired four weeks later, eight months after initial diagnosis.

Decompression retinopathy following nonpenetrating deep sclerectomy for primary congenital glaucoma
|
A 9-day-old Caucasian boy was referred to our department of ophthalmology for bilateral buphtalmia and corneal haze. He was born at term, by spontaneous delivery, of non-consanguineous parents, with no significant personal or family medical history, except a keratoconus in his older brother.\nClinical examination showed no dysmorphic facies, but bilateral megalocornea and buphtalmia, associated with photophobia. Right eye (OD) examination revealed nasal corneal clouding, deep anterior chamber and normal crystalline lens. Funduscopic examination confirmed optic disc cup (cup-to-disc ratio: 0.4) without any vitreous or retinal hemorrhages. Left eye (OS) examination disclosed an epiphora, associated with major corneal edema, deep anterior chamber and normal crystalline lens. Funduscopic examination showed optic disc cup (cup-to-disc ratio: 0.7). Detailed examination under inhalational anesthesia was performed urgently and demonstrated corneal asymmetry up to 1.5 mm (horizontal corneal diameter: 11.5 mm OD and 13 mm OS) and increased axial length in the left eye (axial length: 18.5 mm OD and 19.21 mm OS). The pachymetry showed central corneal thickness of 863 μm OD and 927 μm OS. The IOP (measured with Perkins MK2 tonometer, Haag-Streit, UK) was 22 mmHg OD and 26 mmHg OS. Gonioscopy showed an open angle with normal trabecular meshwork pigmentation in both eyes. Findings included the absence of angle recess and flat iris insertion. There was no peripheral anterior synechiae or embryotoxon (Table ).\nA non-penetrating deep sclerectomy with trabeculotomy was firstly performed in the left eye under general anesthesia.\nThe surgical procedure started with a corneal traction suture temporally and nasally. This is followed by a conjunctival incision and localized tenectomy in the superior quadrant. A pentagonal scleral flap was created of 5 × 4 mm, half the scleral thickness, and dissection was carried forward 2 mm into clear cornea. We used mitomycin C, 0.4 mg/ml for two minutes, followed by careful irrigation. After this, a deep triangular scleral flap was marked, 4 × 4 × 2 mm, and dissection was performed forward until the level of Descemet’s membrane. The inner wall of Schlemm’s canal and the juxtacanalicular trabeculum were peeled off using toothed forceps (25-gauge Eckardt End-gripping Forceps, Dutch Ophthalmic, USA) without perforation of the trabeculodescemetic membrane. Then, a trabeculotomy was made, using the trabeculotome handpiece (Bausch & Lomb E0421 Harms Trabeculotome Set 1.8″ Left Right Ophthalmic, USA). The two third of the trabeculotome length were introduced into Schlemm’s canal to treat, nasally and temporally, an average of 70 degrees of the angle. A space maintainer (cylindrical collagen implant; Aquaflow®, Staar Surgical, Monrovia, CA, USA) was inserted in the scleral bed to prevent collapse of the superficial flap and secured with a single 10/0 Ethilon suture. Closure of the scleral flap and the conjunctiva was done by 10/0 Ethilon sutures and 10/0 Vicryl reabsorbable sutures respectively. The procedure was completed by subconjunctival injection of betamethasone (0,1 ml).\nThe same surgical protocol was performed in the right eye one week after. Postoperative treatment included antibiotic (tobramycin) and steroid (dexamethasone) eye drops, 6 times a day, during one week, followed by gradual reduction of the steroids over a period of 8 weeks and reduction of antibiotic dose.\nOne week postoperatively, the IOP was 11 mmHg OD and 7 mmHg OS. The anterior chamber and the bleb were well-formed in both eyes (Table ). Fundoscopy exhibited a well-circumscribed, crab claw-shaped hemorrhage, corresponding to a pre-macular subhyaloid hemorrhage in the right eye, resulting in an artificially decrease of the OD axial length (Fig. ). Fundus examination of the left eye was unremarkable. Complete blood coagulation analysis was performed and revealed no significant anomaly, excepted moderate polycythemia (hemoglobin: 22.8 g/dL). The patient had no incident of coughing or sneezing postoperatively. A suspected diagnosis of decompression retinopathy was proposed. Close observation was firstly decided. Three weeks after initial surgery, as there was no improvement in subhyaloid hemorrhage, pars plana vitrectomy (25-gauge Stellaris PC System, Bausch & Lomb, Rochester, NY, USA) of the right eye was performed, allowing a complete resolution without any recurrence.\nThree years after initial surgery, the IOP remained controlled in the normal range for both eyes, with reversal of optic disc cupping (c/d 0.1 OD and c/d 0.1 OS). A relevant finding was the onset of high myopia in the OD requiring refractive correction (Table ).

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for pseudomyxoma peritonei in a liver-transplanted patient: a case report

A 48-year-old female patient underwent her first work-up for possible liver disease 30 years ago. Based on findings of chronic active hepatitis in liver biopsy, autoimmune hepatitis was suspected, and treatment with prednisolone and azathioprine initiated. Seven years later, an endoscopic retrograde cholangiopancreatography (ERCP) showed a stricture in the common bile duct which was interpreted as possible extrahepatic PSC or tentatively an inborn anomaly of the common bile duct. After 20 years with fluctuating transaminases between 100 and 300 U/L and no recorded major clinical events, she developed general edema and thoracic spider nevi. A computed tomography (CT) scan revealed liver cirrhosis and portal hypertension with massive ascites. After an initial response to symptomatic treatment, she soon developed uncompensated liver failure with severe hepatic encephalopathy and was transferred to the national transplant unit for work-up and listing for liver transplantation. A few days later, an ABO-identical donor liver was available and LTX was performed with a duct-to-duct biliary anastomosis. The histopathological examination of the liver explant revealed cirrhosis and pathological changes typical for underlying PSC. Cholangiocarcinoma in situ was found in the common hepatic duct, the cystic duct, and the common bile duct, involving the resection margin. It was decided that the patient should be controlled with ERC with brush cytology from the duct-to-duct anastomosis after 6 months due to the histopathological findings. The brush cytology showed mild to moderate epithelial dysplasia in the common bile duct. After discussion in the multidisciplinary team, a pancreaticoduodenectomy (Whipple procedure) was decided due to the risk of development of cholangiocarcinoma. Ten months after LTX, the procedure was performed. Because of a possible increased risk of anastomotic leak due to immunosuppression, an enteropancreatic anastomosis was avoided and the pancreatic duct was occluded. The surgical specimen showed intestinal metaplasia in the common bile duct, but no dysplasia or carcinoma. She was then followed according to standard post-liver transplantation follow-up regimen. The patient developed insulin-dependent diabetes mellitus and received tuberculostatic treatment due to disseminated tuberculosis (pulmonary and meningeal), but the graft function remained good. At the 5-year post-transplantation control, recurrent PSC in the graft was diagnosed on liver biopsy. In addition, a 10 × 4 cm multicystic mass in the lower right abdominal quadrant was described on the routine abdominal ultrasound (US) exam. Upon reassessment, a CT scan of the abdomen performed before the Whipple procedure also showed a 10 × 5 cm multicystic mass in the same region. The lesion was asymptomatic, and based on imaging, the lesion was considered to be a benign gynecological cyst. Consequently, no further investigations were performed to establish the exact etiology. At 10 years of follow-up, the patient reported increasing abdominal distension, anorexia, weight loss, and fatigue for the past 6 to 8 months. Clinical examination revealed extensive sarcopenia, multiple spider nevi, and tense ascites. Biochemical tests showed an iron deficiency anemia with Hgb of 9.0 g/dL, moderately elevated liver function tests, inflammatory markers, and carcinoembryonic antigen (CEA). Imaging, including liver and abdominal US, abdominal and thoracic CT, CT enterography, and positron emission tomography (PET)-CT unveiled liver graft fibrosis/cirrhosis with features of portal hypertension, massive low-attenuating heterogeneous ascites, a focal wall thickening in the middle part of the jejunum, multiple focal lesions in both lungs, a focal lesion in the thyroid gland, and the previously described cystic mass in the lower right abdominal quadrant. Diagnostic abdominal paracentesis revealed thick gelatinous ascites, which was culture negative. The ascites was rich in mucin, but without neoplastic cells on repeated cytology examinations. The provisional primary diagnosis of graft fibrosis-related portal hypertension with ascites could not be supported. Further extensive diagnostic work-up did not confirm tentative diagnoses such as gastrointestinal tuberculosis, sarcoidosis, mucinous tumors of the ovaries, or other causes of peritoneal carcinomatosis. Bearing in mind the differential diagnosis of PMP as a rare, but relevant tentative cause of mucinous ascites, re-evaluation of the contrast-enhanced CT scan raised the suspicion of PMP and that the cystic lesion actually represented a mucinous cystadenoma of the appendix (Fig. ).\nThe multidisciplinary team initially turned down cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for the patient due to concerns of the magnitude of the disease with the risk of harming the graft during the procedure. However, after a renewed assessment, the patient was accepted for explorative laparotomy and potentially CRS-HIPEC. Perioperatively, the peritoneal cancer index (PCI) was estimated to 28 of 39 and it was found that CRS-HIPEC was technically doable and meaningful. The operation time was approximately 11 h. Surgery included removal of considerable amounts of mucinous masses, extensive peritonectomy including the right hemidiaphragm, part of the left hemidiaphragm and the pelvis, omentectomy, hysterectomy, bilateral salpingo-oophorectomy, ileocaecal resection, splenectomy, and removal of the umbilicus. Minimal mucinous masses in relation to the piggyback anastomosis to the inferior caval vein were left due to safety reasons. HIPEC was then performed with mitomycin C for 90 min. The histopathological examination showed perforated low-grade appendiceal mucinous neoplasm and wide-spread mucin without viable tumor cells in all abdominal specimens, compatible with PMP. Forty-two days after surgery, the patient was readmitted with urinary tract infection, anemia, high glucose levels, reversible kidney failure, weight loss, and malnutrition. She recovered on antibiotics and supportive treatment and received follow-up by nutritionists after discharge. Two months after surgery, she had started regaining weight and transplant control displayed satisfactory graft circulation and function (Fig. ).

Profound Trunnion Wear Resulting in Femoral Head-Neck Dissociation in Total Hip Arthroplasty
|
An 88-year-old man, BMI 24, presented to the clinic with complaints of pain and a cracking sensation in his right hip, nine years post primary right THA. His previous medical history was significant for coronary artery disease, myocardial infarction, hypertension, chronic kidney disease, and gastroesophageal reflux disease. His medications included aspirin, metoprolol, ramipril, simvastatin, and ranitidine.\nDuring the initial procedure, the primary components utilized an Accolade #3 stem with a 127-degree neck-shaft angle and +5 36 mm L-fit head. Postoperative course for this patient was uncomplicated. After routine follow-up, at the one-year postoperative mark, the patient was subsequently lost to follow-up. Nine years after the index procedure, the patient returned to the clinic complaining of pain and “cracking” in the right hip for approximately six months. The patient denied any history of injury as well as any subjective infectious symptoms. Radiographic images of the right hip showed an apparent trunnion fracture with significant asymmetric wear of the polyethylene liner within the acetabular component ().\nPreoperative bloodwork revealed normal leukocytes and normal-range C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Thus, the patient was consented for revision THA for a presumed trunnion fracture.\nIntraoperative assessment revealed marked heterotopic ossification along the greater trochanter of the right femur, extending into the gluteus maximus, which was excised and debrided thoroughly. Though the femoral head was intact and showed no gross signs of wear (), there was complete dissociation from the femoral stem. There were also significant signs of metallosis with metal-stained debris and granulation tissue (), which extended deep to the margins surrounding the acetabular shell. Interestingly, the femoral stem demonstrated significant medial trunnion wear (see Figures and ), though no true trunnion fracture was noted, contrary to the initial preoperative radiographic assessment. Stem removal was facilitated by an extended trochanteric osteotomy, and definitive reconstruction was performed with a long cementless femoral stem and Luque wire fixation of the osteotomy. Intraoperative assessment demonstrated a stable final construct (Figures and ). The patient had an uneventful postoperative recovery and at the time of the 6-week follow-up had completed his outpatient rehab protocol with excellent effect.

His-Bundle Pacing in a Patient with Transcatheter Aortic Valve Implantation-Induced Left Bundle Branch Block
|
A 76-year-old man was electively admitted for intervention and management of severe symptomatic aortic stenosis resulting in worsening New York Heart Association Class III cardiac failure. His medical history included stage III chronic kidney disease, type 2 diabetes mellitus, hypertension, and prior coronary artery bypass grafting. Coronary angiography demonstrated a patent left internal mammary artery graft to the left anterior descending coronary artery and a saphenous vein graft to the dominant distal left circumflex artery with a severe stenosis distal to the surgical anastomosis.\nTransthoracic echocardiography was performed and showed a thickened and calcified aortic valve with reduced cusp excursion, mild concentric left ventricular hypertrophy with normal left ventricular cavity size, and systolic function. The left atrium was severely dilated. Left ventricular ejection fraction was above 55%. Valve area was estimated at 0.8 cm2, with a measured mean gradient of 44 mmHg.\nA cardiac conference was held to discuss intervention for his severe aortic stenosis. TAVI was chosen in preference to a redo sternotomy in the setting of the Society of Thoracic Surgeons score of 5.8% (intermediate risk cardiac surgery), stable coronary artery disease, and in accordance with the patient's preference.\nThe preoperative electrocardiogram (ECG) showed sinus rhythm with a narrow QRS complex (). Using a right femoral approach, a CoreValve Evolut R 29 mm (Medtronic, Minneapolis, Minnesota) transcatheter aortic valve was deployed after balloon aortic valvuloplasty with an 18 mm Cristal balloon. TAVI was uneventful. Postdilatation was performed using a 23 mm Cristal balloon due to moderate paravalvular aortic regurgitation around the left coronary cusp seen on a postprocedure transoesophageal echocardiogram. At the time of TAVI, the patient developed LBBB (average QRS duration of 180 ms) with a prolonged PR interval of 240 ms (). Within the first 24 hours post-TAVI, he also had episodes of high-grade AV block.\nA dual-lead Boston Scientific Accolade™ Extended Life DR Pacemaker was implanted via the left cephalic vein (). The HV interval was mildly prolonged at 60 ms. Proximal His capture (selective) threshold was less than 1 V without recruitment of the left bundle branch; RV myocardial capture threshold was 1.5 V at 1 ms; correction of LBBB—due to the presumed capture of distal His bundle and recruitment of the left bundle branch—occurred at 4.5-5 V at 1 ms. A Medtronic 5076 lead was then placed in the right atrial appendage with a threshold less than 1 V. The device was programmed DDD 50. The paced QRS duration on 12 lead ECG was 125 ms consistent with nonselective HBP (para-Hisian morphology) (). At 1 month, 12 lead electrocardiogram tracing showed continued correction of LBBB at 5 V @ 1 ms.

Minimally Invasive Treatment for Tibial Malrotation after Locked Intramedullary Nailing
|
A 49-year-old man sustained a tibial shaft spiral fracture (AO/OTA classification 42-A2) with a fibular fracture (). He had no previous medical history. The fracture was treated initially at another hospital with a reamed statically locked intramedullary nail (). He noted increased external rotation of the affected leg immediately after the surgery. The tibial fracture united after a year (), but he still complained of the asymmetry of his legs, difficulty walking and running, and inability to ride a bicycle. Computed tomography (CT) of both tibias showed 24° of increased external rotation of the affected leg (Figures , ). Because it was a symptomatic rotational deformity, we decided to perform corrective osteotomy in a minimally invasive fashion.\nThe surgical procedure consisted of, first, a 1 cm skin incision at the original fracture site. Multiple efforts were then made to drill around the nail in a radial manner (leaving the nail in place) while using a 3.0 mm Kirschner wire to prepare a percutaneous osteotomy line. Osteotomy for the affected tibia was performed percutaneously using an osteotome on the prepared osteotomy line while retaining the intramedullary nail (). Fibular osteotomy was also done at the same level. Next, two 3.0 mm Kirschner wires, which created a 24° rotational angle in the axial plane between the bone fragments, were inserted as guides for correction (). The distal locking screws were then removed. After matching the two Kirschner wires in a straight line, correct rotation was confirmed (). We assessed the rotational correction intraoperatively to evaluate both sides of the thigh-foot angle [, ]. Finally, the distal three locking screws were inserted into holes different from the original hole (). At 1 year postoperatively, the patient obtained bony union and has returned to his preinjury activities with no symptoms. The implant was removed 1 year postoperatively on the patient's demand. The appropriate correction of the rotational deformity was confirmed on a CT scan (). Postoperative follow-up was continued until 5 years after the corrective osteotomy (). The patient was still free from any symptoms and had full range of hip, knee, and ankle motion.

Spontaneous Macular Hole Closure after Valsalva Retinopathy and Nd:YAG Laser Treatment
|
A 19-year-old young male patient presented to our clinic with sudden vision loss in his right eye 2 weeks after push-up and sit-up exercise. He was admitted to another centre before; he was told that he had haemorrhage in his eye and was advised only follow-up. He had no history of trauma, ocular, or systemic disease. His examination showed that his best corrected visual acuity (BCVA) was counting fingers from 1 meter distance in the right eye, 20/20 in the left eye. Anterior segment examination and intraocular pressure findings were unremarkable. Fundus examination of his right eye showed a well-circumscribed, elevated, and around 4 disc diameter (DD) premacular haemorrhage that extended from the upper vascular arcuate to the fovea. Colour fundus photography and fundus fluorescein angiography were performed. Spectral-domain optical coherence tomography (SD-OCT) revealed dome-shaped elevated lesion with a hyperreflective surface and hyporeflective area underneath (). It was suspected to be the combination of subhyaloid haemorrhage with wider localization and sub-ILM haemorrhage localized only in the fovea. Complete blood counts and biochemical and clotting parameter were ordered for Valsalva retinopathy and other causes of premacular haemorrhage for the differential diagnosis. Internal diseases clinic was consulted. After all the other evaluations, he was diagnosed with Valsalva retinopathy. Treatment options were explained to the patient. He preferred laser treatment.\nNd:YAG laser (VISULAS YAG III, Carl Zeiss Meditec AG, Jena, Germany) and Ocular Abraham Capsulotomy YAG Laser Lens were performed with a posterior approach. The initial energy of laser exposures was 1.9 mJ and then it was gradually increased until it was observed that a rapid stream of blood was trapped into the vitreous cavity. Laser energy was carefully shot onto the anterior surface and inferior margin of the haemorrhage away from the fovea and two openings were made.\nAt the first hour after the procedure, haemorrhage was resolved considerably (). During his follow-up 2 days later, the laser shot sites could be clearly observed and there were only peripherally localized sub-ILM haemorrhage sites. Although his fundus findings were observed to be resolved totally during his control at week 1, BCVA was counting fingers from 3 meter. SD-OCT revealed full-thickness macular hole (). He did not have a marked vision acuity at month 3 and his macular hole findings persisted (). At month 6, BCVA was 20/50, and his fundus examination showed that laser coagulation sites disappeared. SD-OCT revealed the macular hole was spontaneously closed and the normal foveal contour was reformed (). At month 12, the fundus examination and SD-OCT findings were stable, the final visual acuity was 20/32.

Immunoglobulin G4 Sclerosing Cholangitis: An Unusual Cause of Obstructive Jaundice—Case Report and Literature Review
|
An 81-year-old male presented to the clinic with yellowish discoloration of skin and urine for 2 weeks. He denied any fever, abdominal pain, nausea, vomiting, melena, hematochezia, or acholic stools. Past medical history was significant for hypertension, hyperlipidemia, diabetes mellitus type II, coronary artery disease, and chronic kidney disease stage IV. He reported recent loss of appetite but denied any significant weight changes. Ultrasound ordered by primary care physician showed intra- and extra-hepatic biliary dilation with distension of gall bladder without cholelithiasis. He was sent to the emergency department (ED) for further evaluation.\nOn examination, blood pressure was 133/60 mmHg, heart rate was 75 beats per minute, respiratory rate was 23 breaths per minute, temperature was 97.7°F, and oxygen saturation was 98% in room air. He had mild icteric sclera, and chronic venous stasis changes in bilateral lower extremities were noted. Bowel sounds were normal, and no hepatosplenomegaly or abdominal tenderness was noted on exam.\nLaboratory investigations showed a hemoglobin count of 11 g/dl, white blood cell count of (WBC) 3800 cell/mm3, and platelet count of 214,000/mm3. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated at 326 and 321 IU/L, respectively. Total bilirubin was 3.1 mg/dl with direct bilirubin of 1.8 mg/dl. Alkaline phosphatase (ALP) was 1,219 IU/L with lipase 250 IU/L. Renal function tests were at baseline at 1.72 mg/dl (baseline 1.7–1.9 mg/dl). Recent upper and lower endoscopy (1 month earlier) did not show significant abnormalities, except for mild antral gastropathy. A computed tomography (CT) scan of abdomen and pelvis revealed stable pelvic adenopathy with largest lymph node measuring 4.4 × 1.7 cm (which was noted on the earlier CT scan as well). The pancreatic tissue and abdominal vessels appeared normal. With concern for underlying malignancy, a lymph node biopsy was performed. Endoscopic retrograde of cholangiopancreatography revealed distal common bile duct stricture of 3 cm without obstruction, for which a biliary stent was placed. No pancreatic lesions were observed, and biliary brushings were negative for malignancy.\nThe patient returned to the ED two months later; this time with a fever (102°F), nausea, and right upper quadrant pain for 2 days. Complete blood counts revealed elevated white cell count of 18,700/mm3. AST, ALT, and bilirubin levels were within normal limits, and ALP was elevated at 127 IU/L. The CT scan of abdomen revealed intrahepatic biliary ductal dilatation and gall bladder wall thickening with pericholecystic inflammatory stranding with normal pancreas (). He was started on broad-spectrum antibiotics with piperacillin-tazobactam. Urgent surgical decompression with percutaneous drain placement was performed for stent blockage (with re-stent placement) and bile duct stricture from unknown etiology.\nMeanwhile, histopathology from the earlier right iliac lymph node biopsy revealed sinus histiocytic aggregates interlaced with lymphocytes and plasma cells (), majority of cellular constituents being plasma cells, characterized by oval cellular contours and eccentrically located nuclei (); this was confirmed by diffuse immunoreactivity for CD138 (). Chromogenic in situ hybridization for kappa light chain () and lambda light chain () showed a mixture of kappa and lambda-bearing cells (approximate kappa to lambda ratio of 3 : 1); this finding suggested that the plasma cells were reactive in nature, arguing against the possibility of a plasma cell neoplasm. In situ hybridization for EBV-encoded RNA (EBER) was interpreted as negative.\nAs there was no evidence to suggest a lymphoma or a plasma cell neoplasm, a diagnosis of IgG-related disease was considered. Additional immunohistochemistry showed that the plasma cells present expressed predominantly IgG (); of these, the majority (over 60%) were reactive for IgG4 (). Serum protein electrophoresis and immunofixation showed polyclonal increase in IgG with no monoclonal proteins. Serum immunoglobulin (Ig) G levels were high (3390 mg/dl) with normal IgA and IgM. IgG subclasses were also high with IgG1 of 1800, IgG2 975, IgG3 324, and IgG4 729 mg/dl.\nA diagnosis of IgG4-related sclerosing cholangitis was made, and he was started on prednisone 40 mg daily for 6 weeks. A follow-up CT scan of abdomen after a month revealed significant reduction in the size of his pelvic lymph nodes with largest lymph node measuring 1.8 × 0.7 cm (). Endoscopic retrograde cholangiography (ERC) performed revealed resolution of stricture (). The biliary stent was removed following resolution of the stricture. He remains on prednisone 20 mg daily with close rheumatology follow-up. Rituximab therapy is being considered as a steroid-sparing agent.

The Spiraling Case of a Yellow Chef: Isolated Hyperbilirubinemia
|
A 56-year-old healthy man presented to the emergency department in the summer season with three days of fatigue and bilateral thigh pain. He was born in Puerto Rico but resided in the Northeast Region of the US, where he worked as a chef in a major metropolitan city. He had no sick contacts, recent travel, or alcohol or drug use.\nLaboratory data on presentation demonstrated a creatinine (Cr) of 1.73 mg/dL, creatinine kinase (CK) of 3494 U/L and platelet count of 68x103/μL with initially normal liver function tests (LFTs). The patient was admitted for treatment of acute kidney injury from presumed rhabdomyolysis of unclear cause but subsequently developed low-grade fevers, leukocytosis, and worsening thrombocytopenia over the following days. His Cr worsened despite hydration and conservative management for which the patient underwent a renal biopsy on hospital day 4, with findings of acute tubular necrosis, interstitial hemorrhage, and capillaritis.\nIn addition to worsening renal function, he had an impressively rapid rise in his total and direct bilirubin with development of clinical jaundice over the subsequent days with laboratory values on hospital day 8 as follows: Cr of 4, total bilirubin of 41 mg/dL, and direct bilirubin of 38 mg/dL (). The GI consult service became involved in his care and on physical examination noted no evidence of chronic liver disease other than jaundice. The patient had no abdominal tenderness, hepatosplenomegaly, or asterixis. The bilirubin values were out of proportion to his other liver tests such as INR and albumin, which remained within normal values and AST/ALT and alkaline phosphatase values wavered between mildly elevated (<2 times the upper limit of normal) and normal values. Based on the kidney biopsy results and significant hyperbilirubinemia, testing was done for bacteremia, influenza, tuberculosis, HIV, tick-borne diseases, Hantavirus infection, acute viral hepatitis (A, B, C, E, CMV, EBV, and VZV) and vasculitis, which were all negative or normal.\nAn abdominal ultrasound and MRI liver protocol/MCRP showed a normal hepatobiliary system. Given his impressive rise in bilirubin out of proportion to other LFTs in combination with renal failure and rhabdomyolysis, the GI service recommended antibody testing for leptospirosis, for which serum IgM antibodies were checked on hospital day 5. The following day, he was started on empiric doxycycline in liaison with infectious disease consultation at 100 mg intravenously twice daily. In the interim, a liver biopsy was done showing liver parenchyma with marked canalicular and intracellular cholestasis, accentuated in perivenular zone, and rare foci of bile duct injury and ductular proliferation. There was no evidence of significant steatosis, fibrosis or intracellular iron deposition with trichrome, reticulin, PAS-D, and iron stains being unrevealing.\nOn hospital day 10, the Leptospira IgM returned positive, consistent with the diagnosis of icteric leptospirosis. He was continued on doxycycline 100 mg twice daily with subsequent normalization of leukocyte and platelet counts (). In view of the positive Leptospira IgM antibody results, the liver tissue obtained from biopsy was reevaluated for spirochete organisms with special staining; however no organisms were found.\nThe patient completed a 10-day course of doxycycline but unfortunately suffered from bile cast nephropathy from severe hyperbilirubinemia with continued rise in Cr (), for which he was treated with cholestyramine and ursodiol. His liver function tests and kidney laboratory results began to improve thereafter, and he was discharged on hospital day 26. At six-week follow-up, his renal function improved (Cr of 1.4 mg/dL) and his LFTs had normalized. It was later discovered that the restaurant where the patient had been working had a rodent infestation, which were the most likely source of his infection.

Familial Exudative Retinopathy: A Case and Family Analysis
|
A 49-year-old male patient was referred to our clinic with a prediagnosis of retinal vascular occlusion. In his medical history, he reported developing low vision after a traffic accident in childhood, having laser treatment in both eyes at 12 years of age and again 1 month earlier, and undergoing bilateral laser-assisted in situ keratomileusis in 2002. His medical and family histories were otherwise unremarkable. Following fundus examination and FFA, he was questioned again about his birth and he stated that he had been born full term by normal delivery. On ophthalmologic examination, his visual acuity was 0.4 in the right eye and 0.3 in the right eye, with mild cortical lens opacities. Fundus photography showed straightening of the temporal retinal vascular arcades and temporal dragging of the macula in both eyes ().\nPreviously applied laser spots with corresponding preretinal fibrosis were observed in the temporal periphery. Although the nonperfused areas in the temporal retina had been partially laser treated, FFA revealed leakage due to persistent retinal NVE in the right eye ().\nOptical coherence tomography revealed disrupted macular contour associated with epiretinal membrane in the right macula and minimal perifoveal thinning in the left macula ().\nSuspecting FEVR, the patient’s family members were invited for ophthalmologic examination. The patient’s father had normal ocular findings, while his brother showed straightening of the temporal vascular arcades in both eyes and excessive vascular branching and nonperfusing cord vessels in the peripheral vasculature, as well as temporal avascular areas ().\nHis brother was also not born prematurely. FFA was not performed for his brother because he did not return for the procedure. FFA in the patient’s father was within normal limits. Based on the brother’s findings and the revised Pendergast and Trese classification, the patient was diagnosed with stage 2A FEVR and his brother was diagnosed with stage 1A FEVR (). The patient’s other family members did not appear for examination. Additional laser therapy to the nonperfused areas was recommended due to persistent NVE. When obtaining his family history, it was learned that his parents were second-degree cousins.

Possible Association of Papillophlebitis with Guillain-Barré Syndrome: Case Report
|
A 53-year-old woman presented with complaints of visual deterioration in the right eye. Her anamnesis revealed no ocular or systemic diseases except a mild influenza-like illness a week earlier. Her best corrected visual acuity (BCVA) was 0.5 in the right and 1.0 in the left eye. Anterior segment examination and intraocular pressure was within normal range in both eyes. Fundoscopic examination of the right eye revealed splinter hemorrhages, optic nerve head hemorrhage, and cotton wool spots in the superior arcuate region, and the patient was diagnosed with papillophlebitis (). Fundus fluorescein angiography revealed no ischemic areas; however, there was hypofluorescence in the areas corresponding to hemorrhages, and hyperfluorescence in the optic nerve head (). Optical coherence tomography revealed macular edema and intraretinal edema and hyperreflective spots in the nasal fovea corresponding to the areas affected by the occlusion (). Laboratory and radiological tests were requested to determine the etiology of the papillophlebitis. One week after onset of these complaints, the patient began to experience numbness, pain, and tingling sensation in both lower legs. Motor weakness became progressively severe in both extremities and she was admitted to the neurology clinic for advanced examination and treatment. No abnormalities were detected in magnetic resonance imaging of the brain and spinal cord. Complete blood count, electrolytes and blood chemistry and urinalysis were normal. Coagulation tests, including serum levels of homocysteine, protein C and S, partial thromboplastin time, and prothrombin time were normal. Erythrocyte sedimentation rate and anticardiolipin G and M were within normal range. Lumbar puncture revealed no pathology. She was diagnosed with GBS and treated with intravenous immunoglobulin (IVIg) therapy. Her symptoms improved in the following 3 months. During follow-up, her BCVA in the right eye returned to 1.0 without any treatment for ocular findings ().

Optic Neuropathy and Macular Ischemia Associated with Neurosarcoidosis: A Case Report
|
A 26-year-old female patient presented to our clinic with blurred vision in both eyes for 2 weeks. She reported no history of any major illness, but had complaints of fever, sweating, exhaustion, joint pain, and headache starting 2 months earlier. Upon presentation to another center for these complaints, chest x-ray revealed hilar fullness and a thoracic computed tomography (CT) scan was performed. Thoracic CT revealed bilateral hilar lymphadenopathy, and the patient was referred to our hospital for further diagnosis and treatment, where she underwent endobronchial ultrasound-assisted lymph node biopsy in our pulmonary diseases unit. Histopathological examination revealed granulomatous structures, lymphocytes, and sporadic bronchial epithelial cells.\nThe patient was not under treatment when she presented to our clinic. Physically, she exhibited somnolence and clouding of consciousness. Her visual acuity was 20/25 in the right eye and 20/20 vision in the left eye. Granulomatous keratic precipitates and +1 Tyndall effect were detected in both eyes in anterior segment examination. In both eyes, +1 vitritis was observed in the anterior vitreous.\nOn fundus examination, the optic discs of both eyes were edematous and hyperemic. In the right eye, a soft exudate was observed inferior to the optic disc and the lower half of the macula was ischemic (). The patient was started on topical treatment with 1% prednisolone acetate 4 times daily and 0.5% tropicamide 3 times daily.\nNeurology consultation was requested due to the patient’s complaints of intense headaches and the presence of bilateral optic disc involvement. However, no pathology was detected on neuromuscular examination. Cranial imaging and a lumbar puncture were performed. Diffusion magnetic resonance imaging (MRI) revealed extending nodular enhancements within and adjacent to the optic chiasm, at the basal cisternal level, and in the leptomeningeal layers in the posterior fossa. Thoracic and cervical MRI revealed leptomeningeal enhancement adjacent to the entire spinal cord. Cranial MR venography was normal.\nLaboratory tests revealed low hemoglobin (10.7 g/dL; normal: 12-17), high sedimentation rate (57 mm/h; normal: 6-12), elevated CRP (9.4 mg/dL; normal: 0-3.5), and high urinary calcium (324 mg/24 hours; normal: 0-250). Anticardiolipin antibodies and lupus anticoagulants were negative. Cerebrospinal fluid (CSF) analysis showed high protein (145 mg/dL; normal: 15-45) and normal glucose (47 mg/dL; normal: 40-70), cell count in the cytological specimen was high (8500 cells/mL; normal: 0-10), and CSF pressure was normal (12 cm H2O; normal: 8-18). CSF tuberculosis culture and acid-fast bacilli staining was negative. Based on the laboratory values, lymph node biopsy, and imaging findings, the patient was diagnosed with neurosarcoidosis-associated optic neuropathy and treatment was initiated with intravenous 1 g methylprednisolone for 3 days followed by oral methylprednisolone at 1 mg/kg/day. The macular ischemia initially observed in the right eye regressed within 1 week. The patient’s general condition improved significantly with treatment and fundus fluorescein angiography (FFA) was performed. In both eyes, hyperfluorescence beginning in the early phase and increasing in the late phase was observed in the optic discs () and a hyperfluorescent spot that increased in intensity in the late phase was observed on the vessel passing superiorly over the left fovea (). Hyperfluorescent leakage that increased toward the late phase was observed in the lower peripheral retinal vessels of both eyes ().\nAlthough systemic steroid therapy was reduced, it was decided to initiate systemic immunosuppressive therapy; oral methotrexate 15 mg/week and folic acid 5 mg/day were added to her treatment. Her vision was 20/20 in both eyes after 3 months of treatment. Anterior segment examination was normal. Fundus examination showed regression of the optic disc edema (). Follow-up diffusion MRI revealed that the extending nodular enhancements within and adjacent to the optic chiasm at the basal cisternal level and in the leptomeningeal layers in the posterior fossa had disappeared. In addition, thoracic and cervical MRI showed that the leptomeningeal enhancements along the spinal cord had completely resolved and the hilar lymphadenopathy had disappeared.\nThe patient had no systemic or ophthalmological recurrence while under oral 15 mg/week methotrexate and 5 mg/day folic acid therapy or during the 15-month follow-up period. No side effects related to systemic immunosuppressive therapy were observed.

Intravitreal Aflibercept as an Adjunct to Systemic Therapy in a Case of Choroidal Neovascular Membrane Associated with Sympathetic Ophthalmia
|
The blind and painful right eye of a 38-year-old man was eviscerated in September 2016. The patient stated that his right eye had been blind since early childhood due to a unilateral congenital anomaly complicated by secondary glaucoma. He received the diagnosis of SO in January 2017 after he experienced visual loss in his only seeing (left) eye. At the time of diagnosis, the patient was admitted to the hospital and meticulously investigated for possible infectious and noninfectious causes to rule out other uveitic entities, but without any positive findings. At that time, his best-corrected visual acuity was 6/10. Slit-lamp examination yielded some vitreous cells in the left eye. Fundoscopy showed a few scattered pigmented chorioretinal scars and discrete yellowish round choroidal lesions throughout the left fundus (). Fluorescein angiogram delineated the active lesions as early hypofluorescent () with late staining. Left macular contour was normal on optical coherence tomography (OCT) examination (). He was started on oral prednisolone (64 mg) for 2 weeks with gradual tapering of 8 mg per week. Despite initial visual improvement, he experienced another episode of visual decline while taking 32 mg of prednisolone. His best-corrected visual acuity decreased to 2/10 and he had grade 4 vitreous haze according to the Miami grading. Fundus examination showed marked yellowish-white discoloration of the macula with some evidence of intraretinal hemorrhage ( and ). He was hospitalized and treated with pulse methylprednisolone 1 g (250 mg 4 times daily) for 3 days. Following pulse therapy, 64 mg oral prednisolone and 150 mg (50 mg 3 times daily) azathioprine were co-administered. Two weeks after the completion of pulse therapy, his visual acuity was still 2/10 despite a significant reduction in vitreous haze. Fluorescein angiogram and OCT demonstrated type 2 choroidal neovascularization (). Five intravitreal 2 mg aflibercept injections were given within a period of 8 months. His final visual acuity was 6/10 with a stable-looking macula ( and ) and he was continued on a treatment regimen of 150 mg azathioprine and 8 mg prednisolone daily.

A 27-Month-Old Boy with Polyuria and Polydipsia
|
A 27-month-old boy was referred for a second opinion regarding polyuria and polydipsia of sudden onset four months prior to presentation. He drank between 3 and 4 L of water per day and had frequent heavy wet diapers, decreased appetite, and a 1-pound weight loss. He had no prior episodes of dehydration or any preceding or intercurrent illnesses. He had no prior medical history, met normal developmental milestones, and was not taking any prescribed or over-the-counter medications. There was no family history of diabetes insipidus. Social history was remarkable for the mother returning to work prior to the onset of symptoms.\nPrior evaluation was significant for normal serum sodium, glucose, blood urea nitrogen (BUN), creatinine, adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), thyroxine level, insulin-like growth factor (IGF), cortisol, erythrocyte sedimentation rate (ESR), and prolactin. The random arginine vasopressin (AVP) level was 1.4 pg/mL (normal range 1–13.3 pg/mL) with a random urine osmolality of 285 mOsm/kg. A head MRI did not reveal any pituitary or other intracranial pathologies. A renal ultrasound showed a right kidney with a duplicated collecting system with mild prominence of the lower pole of the renal pelvis. An informal water deprivation test was conducted at home, and parents were instructed to limit water intake at home overnight and to return for laboratory evaluation in the morning. Urine osmolality was 683 mOsm/kg after 12 hours of water deprivation. However, mother stated that, at the end of the water deprivation, she had to give him water to stimulate diuresis. No serum osmolality or sodium levels were collected. He was diagnosed with partial DI and started on oral desmopressin (DDAVP). The dose of DDAVP was titrated up to 0.2 mg twice daily for effect, his polyuria and polydipsia resolved, his appetite improved, and he began to gain weight.\nVital signs were normal, with weight-for-age at the 45th percentile, height-for-age at the 57th percentile, and body surface area 0.57. Physical exam was remarkable only for a tired-appearing toddler. Chemistries performed were remarkable for serum sodium of 121 mEq/L. DDAVP was discontinued, and the serum sodium normalized to 138 mEq/L 24 hours later.\nHe was admitted to the hospital for a water deprivation test. After eight hours of observed water deprivation, urine osmolality increased from 270 mOsm/kg to 753 mOsm/kg. During this observed period, urine output was 4 ml/kg/hour and total weight loss was 160 grams. Serum sodium was 139 mEq/L and 140 mEq/L and serum osmolality was 298 mOsm/kg and 294 mOsm/kg, before and after water deprivation, respectively. He was discharged home with fluid restriction to 1.5 L/day. Since discharge from the hospital, parents were able to reduce his water intake with resolution of polyuria. However, he continued to ask for water to help him fall asleep at night. Retrospectively, his mother suspects that water drinking was his method for self-comfort following her return to work.

Nodular Pulmonary Amyloidosis: A Manifestation of Sjögren's Syndrome
|
The case is of a 72-year-old female, chronic smoker patient with a 3 pack-years until 20 years ago, with a personal history of hypertension, obesity, dyslipidemia, breast nodules, and transverse myelitis with motor sequelae. She has been hospitalized 6 years ago for community-acquired pneumonia.\nShe consulted for several months of asthenia, adynamia, hyporexia, and subjective weight loss. Associated with this, she had 10 days of fever, malaise, myalgias, non-palpable purpura on the lower limbs (), mild dyspnea, and intermittent cough without hemoptysis.\nShe had dry symptoms (xerostomia and xerophthalmia) initiating a study for primary SS during hospitalization. She had a positive Schirmer tear test, antinuclear antibodies 1:160 with a speckled pattern, positive anti-Ro/SSA, and anti-La/SSB, as well as positive rheumatoid factor and mild C3 hypocomplementemia. The diagnosis of SS was confirmed with a minor salivary gland biopsy that reported chronic sialadenitis with Chisholm-Mason grade of 4.\nHer physical examination did not present hemodynamic instability; she was afebrile with a few bibasilar rhonchi without respiratory difficulty. She had urinary incontinence, nonpalpable purpuric lesions on the lower limbs, and decreased distal muscular strength, partially limiting the gait. During her stay, she presented respiratory and metabolic acidosis with a blood urea nitrogen/creatinine ratio> 20 that was corrected with supplemental oxygen and intravenous fluids. Her exams were performed, including a complete blood count, complete liver function tests, serum electrolytes, and acute phase reactants, which were found in normal ranges. She also had negative hepatitis C virus (HCV) antibody test and nonreactive tests for human immunodeficiency virus (HIV) and syphilis. The serum protein electrophoresis: mild broad-based peak in the gamma region (<3 g/dL) and skin biopsy reported capillaritis with no histological signs of malignancy.\nThe possible associated pathologies in SS, like non-Hodgkin lymphoma, mainly of mucosa-associated lymphoid tissue (MALT) type, ANCA-associated vasculitis, and cryoglobulinemic vasculitis were ruled out.\nIn this context, due to pulmonary nodular involvement evidenced in the non-contrast computed tomography (CT) scan of the chest, an HRCT was requested (Figures and ) which showed multiple generalized, noncalcified nodular lesions, some with cavitations, and the presence of focal areas of ground-glass opacity associated with suggestive basal predominance subpleural cysts that are suggestive of lymphocytic pneumonia. The CT-guided lung biopsy was considered to clarify its etiology as there were no findings of neoplastic foci in the extension studies (non-contrast head CT scan, non-contrast abdominal CT scan, transthoracic echocardiography, mammography, and upper digestive endoscopy).\nFiberoptic bronchoscopy did not report any anatomical abnormalities or evident lesions in the pharynx, hypopharynx, larynx, main bronchus, interlobar bronchus, lobular bronchus, or segmental bronchus. In the left main bronchus, there were scarce and diffuse mucohemorrhagic secretions in the bronchial tree, predominating in the bronchus for the upper left lobe, with no evidence of apparent active bleeding. Microorganisms were not isolated in bronchoalveolar lavage. Bronchial brushing showed a benign cytological pattern, acute inflammation, and negative special staining for mycobacteria and fungi.\nSubsequently, video-assisted thoracoscopy (VATS) was performed with pulmonary biopsy. The biopsy of the upper lobe and lingula of the left lung had as findings distortion of the parenchyma architecture, pleural thickening with the presence of anthracite pigment, and alveolar septa thickened with inflammatory infiltration of lymphocyte predominance. Presence of inflammatory infiltration of peribronchiolar lymphocyte predominance in some lymphoid nodules is shown in . There was formation of nodules with dense amorphous eosinophilic material, in the middle of which there are lymphoplasmacytic inflammatory cells. In addition, with positive CD3: immunohistochemical markers for reactive T lymphocytes, CD20: for reactive B lymphocytes, and CD38: for plasma cells and kappa and lambda positivity, similar areas of nodular formation were found with amyloid deposition using special staining for crystal violet () and Congo red ().\nWith these findings, the diagnosis of nodular pulmonary amyloidosis and non-specific interstitial pneumonia (NSIP) was made. Both pathologies were explained by the SS. Inpatient immunosuppressive treatment was with cyclophosphamide 800 mg IV single dose and methylprednisolone 150 mg IV single dose; subsequently, on an outpatient basis, prednisolone 50 mg PO qd was administered for one month with gradual reduction.

Two successful cases of DIEP flaps for breast reconstruction in patients with Factor V Leiden
|
The first case describes a 48-year-old female who had an established diagnosis of heterozygous FVL with a positive family history and was diagnosed with left breast cancer in October 2010. She presented to our institution in November 2013 with painful capsular contracture from prior implant-based reconstruction and a desire for bilateral autologous reconstruction. After detailed counseling regarding her operative risks, she underwent bilateral implant removal, capsulectomy and bilateral sensate DIEP flaps. There were no significant perioperative adverse events. The patient received 3000 IU of intravenous unfractionated heparin (UFH) after both sets of anastomoses were performed. At her 2-year follow-up at our institution in early 2016, the patient was in good health with her flaps sensate and well-perfused (Fig. ).

Two successful cases of DIEP flaps for breast reconstruction in patients with Factor V Leiden
|
The second case involved a 49-year-old female who was diagnosed with infiltrating ductal carcinoma in 2010. After initial lumpectomy and subsequent chemoradiation, she presented in 2016 expressing desire for mastectomy of the left breast with autologous breast reconstruction. Her history was significant for heterozygous FVL and a previous lower extremity deep venous thrombosis which required 2 years of warfarin therapy. She underwent left completion mastectomy with neurotized DIEP flap reconstruction. There was clotting noted intraoperatively prior to performing the anastomosis, and the decision was made to irrigate the vessels with tissue plasminogen activator solution. The patient was given an intravenous dose of 3000 units of UFH. At her 1-year follow-up in August 2017, her flaps and abdominal scar were inconspicuous and the patient was awaiting her symmetry breast revision procedures (Fig. ).\nAll lab values of both patients are displayed in Table and their medications in Table . The TEG® 5000 Thromboelastograph® Hemostasis System (Haemonectics Corporation, Braintree, MA) was the device performing all TEG tests. Additionally, the thrombocyte count, prothrombin time (PT) and activated partial thromboplastin time (aPTT) were obtained.

Prosthetic Tricuspid Valve Thrombosis
|
A 42-year-old female with a history of morbid obesity and tricuspid valve endocarditis with mechanical TV replacement, who had stopped taking Coumadin for one week, presented with worsening dyspnea, facial cyanosis, marked lower extremity edema, and increased abdominal girth. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) revealed significant tricuspid valve thrombosis with severely immobile leaflets and severe pulmonary hypertension (Figures -).\nShe was initially started on a high-intensity heparin infusion with 8000U bolus followed by 1800U per hour infusion. She was brought to the interventional laboratory where a 7-French triple-lumen central venous catheter was advanced to the right atrium via the right internal jugular vein under fluoroscopic guidance. A bolus of 2 mg of alteplase (tPA) was delivered followed by a continuous infusion of 1 mg/hour for 24 hours. Fluoroscopy revealed a tricuspid valve with severely reduced mobility (Figure ).\nThe gradient across the tricuspid valve was above 20 mmHg and right atrial pressure was elevated at 22 mmHg. Repeat gradients were assessed 24 hours later, and TV gradient remained elevated above 20 mmHg, with severely elevated central venous pressure, and markedly reduced cardiac index. The patient underwent redo sternotomy with redo tricuspid valve replacement with a porcine bioprosthesis. Her postoperative course was uneventful. She was started on coumadin and bridged with heparin infusion and was discharged home with INR 2.6.

Effect of Albumin Polymorphism on Thyroid Hormones: A Case Report and Literature Review
|
A 79-year-old Hispanic male with a history of hypertension, schizoaffective disorder, benign prostatic hypertrophy, and chronic renal insufficiency was admitted for evaluation of a wide complex tachycardia found on his outpatient 24-hour Holter monitor done to evaluate his complaint of frequent palpitations. The patient acknowledged that he had palpitations for several years and that he was always nervous. He also stated that this “nervousness runs in the family”. There was no associated weight loss, unusual hair loss, or visual changes. He also denied any neck mass/goiter, diarrhea, or abdominal skin rash/thickening but stated that his hand always “shakes”. He denied any chest pain or shortness of breath, either at rest or with exertion. He also denied any orthopnea or paroxysmal nocturnal dyspnea but had complained of chronic leg swelling with no recent change. Exercise tolerance remained very good and unchanged.\nOn admission, an endocrinology consult was requested for evaluation of persistently elevated TT4 and FT4 levels. His vital signs were stable and physical exam revealed a mildly anxious elderly male with coarse tremors of the hands on extension. The rest of the examination was unremarkable. A sonogram of the thyroid gland showed bilateral prominent lobes, the left greater than the right. A thyroid iodine (I)-123 uptake scan was 19.4% (normal level: 15 - 40%). It also showed a mildly enlarged but non-palpable lower pole of the thyroid lobe with homogenous activity throughout the gland. Thyroid function tests (TFTs) done using routine automated direct one-step/two-step immunoassays showed normal TSH levels of 1.22 and 0.78, respectively (normal level: 0.34 - 5.6 mU/mL). T3 levels were normal at 98.4 and 125.3 ng/dL (normal level: 87 - 178 ng/dL). However, TT4 and FT4 levels were elevated. FT4 levels were 2.25 and 2.34 ng/dL (normal level: 0.58 - 1.64); and TT4 levels were 17.58 and 18.69 (normal level: 6.09 - 12.2). Free T3 by equilibrium dialysis was 402 ng/dL (normal level: 230 - 420) and an alpha subunit for pituitary hormone was less than 0.3 ng/ml (normal level: < 1.0). Free T4 by equilibrium dialysis was normal at 2.1 ng/dl (normal level: 0.8 - 2.7).\nCardiac workup, including echocardiogram, cardiac enzymes, stress test, and telemetry monitoring, was unremarkable. He was treated with a beta-blocker and discharged after being assured that his thyroid condition was benign.

Pneumothorax During Cervical Paraspinal Muscle Electromyography: A Case Report
|
A 49-year-old woman presented to our neurology clinic with complaints of pain and weakness in her upper-right and lower-left extremities, lower back pain, and numbness in her lower extremities for many years. For the past couple of months, the pain in her lower back, left hip, and lower extremities (including feet) has gotten worse. The pain increased at night, was exacerbated while standing or sitting, and was accompanied by numbness in her left lateral thigh. The rest of her medical history was unremarkable. The nerve conduction studies showed mild but painful sensory axonal neuropathy with superimposed mild bilateral sensory carpal tunnel syndrome. During the needle EMG using a 50 mm * 25 gauge needle, she complained of a significant amount of discomfort when her right cervical paraspinal muscles were punctured; however, she did not exhibit any other symptoms. After the EMG study, her blood pressure was 156/103 mmHg, with a pulse rate of 90/min (right radial, sitting), then it was 154/101 mmHg with a pulse rate of 97/min. She was given the appropriate treatment, which included blood tests to eliminate correctable causes of neuropathy, vitamin B12, exercise, and appropriate medications.\nAfter leaving the clinic symptom-free, she returned 30 minutes later, with complaints of right-sided pleuritic chest pain and the coughing up of some mucus. Upon physical examination, she had a tender right pectoralis major muscle, equal breath sounds bilaterally, a normal cardiac examination, a blood pressure of 130/80 mmHg, and a pulse of 100/min (right brachial, sitting). She was immediately sent to the emergency room for a workup, including a chest X-ray, which disclosed a 15% right-sided pneumothorax. This was most likely due to the needle EMG puncture of her right cervical paraspinal muscles. The patient was admitted overnight for non-rebreathing oxygen treatment. Once her symptoms were resolved, she was discharged with a follow-up to ensure that her pneumothorax had resolved.

Low Dose Naltrexone and Lung Cancer: A Case Report and Discussion
|
A 50-year-old male who is an established patient of ours underwent preoperative evaluation in August 2013, which revealed an abnormality not present in the imaging taken in 2011. His chest X-ray revealed a prominence in right hilum and a density along the right pleura towards the right upper lobe. Later, the patient underwent noncontrast computed tomography (CT) of the chest depicting pleural-based mass measuring 3.3 cm x 3.7 cm in the right upper lobe (Figure ). Biopsy performed a few weeks after imaging showed adenocarcinoma,\npoorly differentiated with a solid and single cell pattern. Molecular genetics was positive for thyroid transcription factor-1 (TTF-1), which is found in type II pneumocytes and Clara cells. Evidence suggests that TTF-1 expression is associated with better overall survival []. A full body positron emission tomography (PET) revealed a hypermetabolic spiculated 4.4 cm x 3.2 cm mass in the right upper lobe of the patient (Figure ). Also, a pathologic hypermetabolic right suprahilar lymph node measuring 1.8 cm x 2.4 cm. was noted. The standardized uptake values (SUVs) were 12 and 5.8, respectively. On November 25, 2013, the patient underwent right upper lobe lobectomy and frozen section determined tumor, node and metastases (TNM) classification to be T3, N1, and Mx.\nAfter resection, the patient began concurrent chemo-radiotherapy with cisplatin and pemetrexed on January 15, 2014. He declined further chemotherapy treatments after the second treatment session citing intolerable side effects such as nausea, vomiting, fatigue, and malaise. However, he completed the radiation regimen, which lasted for a total of six weeks.\nIn subsequent weeks and months, the patient faced numerous challenges including several admissions for pneumonia, fluid overload, and bronchospasms. Later, he was admitted for pulmonary embolism, which led to the addition of rivaroxaban for life and placement of an inferior vena cava (IVC) filter. The patient has a history of permanent tracheostomy for chronic hypercapnic respiratory failure in 2006 along with a radical prostatectomy due to a Gleason 7 prostate carcinoma in 2008. Subsequently, after many positive antidotal cases in our practice utilizing LDN, a decision was made to try and start the patient on this complementary therapy. Therefore, he was started on LDN 4.5 mg HS on July 23, 2014. Imaging performed following LDN has been unremarkable. More specifically, a PET scan performed on October 27, 2017, and computed tomography (CT) of chest/abdomen/pelvis with contrast performed on April 25, 2018, have been negative for evidence of any recurrence. The patient is currently on rivaroxaban, amlodipine, atorvastatin, clonidine, insulin lispro, insulin glargine, losartan, metoprolol, prednisone, montelukast, diltiazem, and LDN.

The Nail Flag Sign: Case Report in a Man with Diverticulitis and Review of Dermatology Flag Sign of the Hair, Skin, and Nails
|
A 75-year-old man presented for his semiannual total body skin evaluation. His past medical history was significant for diverticulitis of 27 years duration. Three months earlier, the treatment of his abdominal pain had necessitated a sigmoid resection—with a concurrent appendectomy—and an end colostomy with mucous fistula.\nHe also has anxiety (for which he takes alprazolam, as needed) and mitral valve prolapse (for which he takes diltiazem daily). In addition to his recent operation, his prior surgery includes the repair of an anal fistula with a rectal advancement flap.\nHis history of skin disease includes a basal cell carcinoma on the right side of his neck that was excised five years ago and actinic keratoses on sun-exposed skin that have been treated with cryotherapy. He developed psoriasis as a middle-aged adult; his psoriasis is limited to less than 5% of his body surface area; individual plaques were treated initially with clobetasol propionate 0.05% cream or solution followed by triamcinolone 0.1% cream, each applied twice daily for three to five days. He also had a history of allergic contact dermatitis to bandaid adhesive and congenital idiopathic leukonychia that has been present since early childhood.\nCutaneous examination showed eight keratotic plaques on the sun-exposed areas of his face, arms, and legs; the actinic keratoses were treated with liquid nitrogen cryotherapy. Psoriasis lesions were also present, appearing as small, red scaly plaques on the chest, arms, and legs. There were no nail plate changes of psoriasis.\nEvaluation of his fingernails and toenails confirmed the presence of leukonychia; all of the nail plates on his fingers and toes showed diffuse whitening (Figure ). His thumbnails also demonstrateed alternating horizontal bands of white and red beginning at the proximal nail fold and extending to the tip of the nail plate: the nail flag sign (Figure ). In addition, the surfaces of both thumbnail plates had longitudinal striations.

A Case of Herpes Zoster Presented with Lower Limb Paresis
|
A 48-year-old female patient visited the emergency room (ER) due to left buttock pain after she slipped down on her way to the bathroom. The accident occurred just before she visited the ER, while the left buttock pain started two weeks ago. The patient denied for any remarkable medical history except for being a hepatitis B virus carrier. According to the ER records, she had a generalized fever up to 37.8°C and had tenderness, swelling on her left buttock and proximal area of the posterior thigh. The blood laboratory test showed elevated C-reactive protein (CRP) level (4.08 mg/dl) without leucocytosis (WBC: 6930/μl). The liver enzyme values were mildly elevated such that serum glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were 68 and 45, respectively. The plain radiography showed no evidence of fracture around her hip joint. The emergency medicine physician had a clinical impression of early stage cellulitis or contusion of hip and she was discharged from ER after prescribing empirical antibiotics and nonsteroidal anti-inflammatory medications.\nA week later, she visited the orthopedic outpatient department with aggravated pain and weakness on her left lower extremity. The vital signs were unremarkable. On physical examination, she had a left foot drop and was unable to dorsiflex or plantar-flex her left ankle. Extension of the great toe was also impossible. Hypoesthesia was detected on L4, 5, S1 dermatomes. Deep tendon reflexes on patellar and Achilles tendon were normal and symmetrical. A patchy erythematous rash with sharp pain existed on the left buttock and posterior thigh without any sign of vesicle formation. The blood laboratory test showed mildly elevated CRP (2.03 mg/dl) and normal procalcitonin (0.05 ng/ml) levels. Due to the aggravated sciatica and left lower limb weakness, the lumbosacral magnetic resonance imaging (MRI) was urgently performed under suspicion of a spinal lesion. The MRI revealed mild bulging disc with bilateral facet arthritis at L4-5 level; however, it was not thought to be the direct cause of the symptoms. The result of electromyography and nerve conduction velocity (EMG-NCV) tests showed severe left sciatic neuropathy that no motor nerve responses from the left peroneal nerve and reduced compound muscle action potential on tibial nerve were found. Pelvis MRI with contrast enhancement revealed asymmetrical diffuse swelling of the left sciatic and femoral nerve, which suggested neuritis (Figure ).\nA more detailed investigation on her past medical history revealed that she had been treated for herpes zoster infection of the left buttock three years ago. A thorough systematic review was done again; however, she had no comorbidity or medication history that can cause immunosuppression. The putative diagnosis of herpes zoster was confirmed by detecting VZV DNA from her blood sample using the polymerase chain reaction test. The patient was treated with famciclovir 500 mg every eight hours and 20 mg/day of prednisolone for two weeks and changed to oral pregabalin 75 mg every 12 hours thereafter. After 12 weeks of an inpatient rehabilitation admission, she had a partial neurological recovery and could walk with a foot drop splint. The manual muscle test showed that muscular strength of her left ankle dorsi-flexor, plantar-flexor and great toe extensor improved to grades II, III, and III, respectively. The hypoesthesia of S1 dermatome was completely recovered, while L4, L5 dermatomes showed 50% improvement. Also, the skin rash and pain around it was completely alleviated. Follow-up pelvis MRI taken at 10 weeks after the treatment showed markedly diminished swelling of the left sciatic and femoral nerve (Figure ).

Alpha-fetoprotein-producing rectal cancer successfully responded to preoperative chemoradiotherapy: case report
|
A 68-year-old man was referred to our hospital with diagnosis of rectal tumor. Medical history notably included diabetes mellitus, but family and social history were unremarkable. Colonoscopy identified a two-thirds circumferential type 2 tumor in the rectum, about 5 cm from the anal verge (Fig. a). Biopsy of the tumor revealed well differentiated tubular adenocarcinoma and papillary adenocarcinoma with enteroblastic differentiation which was characterized by clear cytoplasm and regarded as one of the histological features in AFP-producing cancer (Fig. ). Laboratory evaluation showed fasting blood glucose and HbA1c levels were elevated at 152 mg/dl (normal range 73–109 mg/dl) and 13.7% (normal range 4.9–6.0%), respectively. Serum tumor marker levels were increased to 8.8 ng/ml in CEA (normal range ≤ 5.0 ng/ml) and 28.3 ng/ml in AFP (normal range ≤ 7.0 ng/ml). Two-thirds circumferential thickening of the wall over 4 cm in the lower rectum, and a pararectal lymph node swelling about 8 mm in diameter was revealed by enhanced abdominal computed tomography (CT) and pelvic magnetic resonance imaging (MRI) (Fig. a). The tumor was classified as stage IIIB (T3N1M0). To improve the local control rate and the survival rate, preoperative radiation therapy (total dose of 45 Gy/25 fractions) with capecitabine (1,650 mg/m2/day) was performed. Effective tumor reduction was observed on colonoscopy, CT, and MRI after 5 weeks of the above treatment. A swelled pararectal lymph node also showed a significant decrease of its size from 8 to 3 mm in diameter (Fig. , ). In addition, serum tumor marker levels decreased to normal range: CEA, 2.0 ng/ml; AFP, 3.7 ng/ml. At 7 weeks, low anterior resection with temporary diverting ileostomy was performed. Histopathologically, residual poorly differentiated, non-solid type adenocarcinoma was present, although most of the tumor comprised fibrous scar tissue. There was no lymph node metastasis, and pathological diagnosis was stage I (T2N0M0). Histological evaluation of the treatment with chemoradiotherapy was assessed to be grade 2 according to the Japanese Classification of Colorectal Carcinoma []. Immunohistochemical studies yielded positive results for AFP, Sal-like protein 4 (SALL4), and glypican3 (GPC3) (Figs. , ). The postoperative course was uneventful. Four weeks after the operation, serum tumor marker levels had decreased to 1.2 ng/ml in CEA and 1.6 ng/ml in AFP. The patient received adjuvant chemotherapy with capecitabine and oxaliplatin (CAPOX) for 3 months in consideration of high recurrence rate in AFP-producing cancer. After completing this regimen, we checked no signs of recurrence. To date, he has not developed any recurrence for 6 months after the operation.\nAFP is a serum glycoprotein frequently detected in patients with hepatocellular carcinoma and yolk sac tumors [–]. Its production has also been reported in malignant tumors of various organs, such as the bile duct, the pancreas, and particularly the stomach [, ]. AFP-producing colorectal cancer, however, is extremely rare. AFP-producing gastric cancers are associated with aggressive clinical behavior and poorer prognosis compared to AFP-negative gastric cancer because of a significantly higher incidence of vascular invasion, lymph node metastasis, and liver metastasis [, , ]. As for AFP-producing colorectal cancers, a similar tendency has been observed in previous reports and their reviews of up to 12 patients [–]. Patients with AFP-producing colorectal cancer underwent several treatments, including surgery and chemotherapy according to conventional colorectal cancer treatment. There are no confirmed treatment strategies, however, and about half of the patients died within a year of therapeutic intervention. The present case was of rectal cancer classified as stage IIIB (T3N1M0), so we elected to perform the preoperative chemoradiotherapy that is recommended for cases clinically diagnosed as deeper than T3 or node-positive rectal cancer. The aim was to improve the local control rate and the survival rate [–]. As of chemotherapy regimen for preoperative chemoradiotherapy, we chose capecitabine alone according to the papers describing that preoperative radiation therapy with capecitabine was as effective as with intravenous infusional fluorouracil, but the addition of oxaliplatin did not improve surgical and oncological outcomes [, ].\nAlthough there are no reports of AFP-producing rectal cancer treated with radiation therapy, several reports in hepatocellular carcinoma and a few reports in yolk sac tumor have shown its effectiveness [–]. In our case, effective tumor reduction was observed and serum tumor marker levels decreased to normal range by this treatment. After 7 weeks of the above treatment, the operation was performed. Although pathological findings showed R0 resection, immunohistochemical studies revealed AFP production. The tumor was therefore diagnosed as AFP-producing adenocarcinoma. Immunohistochemical studies also yielded positive results for SALL4 and GPC3; known novel oncofetal proteins expressed in germ cell tumors. SALL4 and GPC3 are also highly expressed in AFP-producing gastric cancers [], but there are no reports on their expression in AFP-producing colorectal cancers. In this case, as with AFP-producing gastric cancers, fetal differentiation may be induced, and immunohistochemical studies showed positive results for these oncofetal proteins. SALL4 expression in colorectal cancer is reportedly associated with lymph node metastasis and poor prognosis []. Although our case was pathologic stage I which was not normally needed for adjuvant chemotherapy in AFP-negative colorectal cancer, he was deemed to have a high probability of recurrence, and hence, adjuvant chemotherapy was performed. As effective therapies against AFP-producing colorectal cancer have not been established, regimen is performed according to various guidelines and personal experiences. Our patient received CAPOX treatment for 3 months according to the latest guidelines, and the report showing 3 months of therapy with CAPOX was as effective as 6 months in patients with stage III colon cancer even among those with high-risk factors [, ].

Are complicated monochorionic twins more susceptible to indomethacin-induced fetal ductal constriction? Two cases of laser surgery for Twin-Twin Transfusion syndrome
|
A 24-year-old gravida-3-para-2 at 24 weeks’ gestation was referred to our department for TTTS. Her physical and gynecologic examinations were usual. Fetal examination revealed a diamniotic MC twin pregnancy. The recipient twin was diagnosed as having polyhydramnios and the donor twin had oligohydramnios. The diagnosis of stage 3 TTTS was made on the basis of Quintero Staging system. A negative ductus venosus A-wave was observed in the recipient twin. The deepest vertical pocket was 140 mm for the recipient and 5 mm for the donor twin. The complications and prognosis of TTTS and risks of placental laser surgery were discussed with the family and the patient opted for placental laser surgery. The patient underwent placental laser surgery under local anaesthesia in operating room. On the day of the operation, 100 mg indomethacin was administered due to regular uterine contractions as rectal suppository once a day. Indomethacin administration was continued until postoperative day 2 and the contractions disappeared. On postoperative day 3, an ultrasound examination revealed pleural effusion, ascites, increased nuchal thickness, oligohydramnios, tricuspid regurgitation, and negative ductus venosus A-wave in the donor twin and normal Doppler findings in the recipient twin. A detailed examination of the ductus arteriosus showed ductal narrowing with a transverse diameter of 1.49 mm (<5th percentile) ()(. There was no turbulent flow or aliasing in the ductus arteriosus region and systolic and diastolic velocities were 69 and 6 cm/s, respectively. Although Doppler criteria of ductal constriction were not observed, hydrops was prominent. The indomethacin treatment was stopped. The direction of ductus venosus flow turned to positive on the next day and further examination revealed a 50% increase in the transverse diameter of the ductus arteriosus, and the ductal arch returned to its normal shape (). The tricuspid regurgitation and ascites, and pleural effusion disappeared completely on postoperative days 5 and day 7, respectively. The patient was discharged on tenth day postoperatively. Her antenatal visits were uneventful until delivery. The patient underwent a cesarean section for breech-vertex presentation at 35 weeks’ gestation. Male infants weighing 2200 and 2100 g were delivered.

Are complicated monochorionic twins more susceptible to indomethacin-induced fetal ductal constriction? Two cases of laser surgery for Twin-Twin Transfusion syndrome
|
A 25-year-old gravida-2-para-1 at 20 weeks’ gestation was referred to our department for TTTs. The patient reported abdominal bloating. The diagnosis of TTTs stage 2 was made on the basis of Quintero staging. The deepest vertical pocket was 154 mm for the recipient and 10 mm for the donor twin. The estimated foetal weight (EFW) was less than 10th centile for donor twin. Placental laser surgery was performed after preoperative counselling. Postoperatively, a single-dose 100 mg indomethacin suppository was inserted into the rectum to prevent uterine contractions. On the next day (postoperative day 1), constriction of the ductus arteriosus and tricuspid regurgitation were observed in the donor twin. There was a marked ductal narrowing (). The peak systolic velocity was 149 cm/s (). On postoperative day 3, the transverse diameter of the ductus arteriosus and peak systolic velocity returned to normal (). On postoperative day 5, the tricuspid regurgitation had disappeared and the patient was discharged. On the next day, the patient was admitted to the hospital due to regular contractions and cervical opening and she delivered at 21 weeks and 3 days’ gestation.

|
A 64-year-old woman, gravida 2, para 2, presented with pelvic pain, which she had had for approximately four months. She underwent a ventro-suspension 25 years ago for uterine prolapse. However, a re-operation for uterine prolapse consisting of laparoscopy-assisted vaginal hysterectomy was performed 3 years ago. During this procedure, the uterus was separated from bilateral cornual regions and adnexae were left. The result of a pathologic evaluation was reported as benign for the uterus corpus material but wide cervical intraepithelial grade 3 neoplasia signs for the cervix were reported. A physical examination revealed a pelvic mass fixed to the left anterolateral abdominal wall. Abdominal magnetic resonance imaging revealed a huge mass in the pelvic cavity backward the bladder with irregular borders. The tumor markers were carbohydrate antigen (CA)-125; 269.7 kU/L (reference value; 0-35 kU/L). She underwent a debulking operation with bilateral salpingoopherectomy and total omentectomy, bilateral pelvic and paraaortic lymph node dissection, appendectomy, and aspiration for cytologic evaluation. The left ovarian mass had invaded the abdominal wall and resection of the fascia and part of the rectus abdominis muscle was needed; a polypropylene mesh was used to close the abdominal wall. There was no visible tumor after surgery. The tumor was characterized by a proliferation of small, round, primitive cells with a diffuse growth pattern. The cells had scant cytoplasm, irregularly-shaped and hyper-chromatic nuclei with coarse chromatin and a brisk mitotic rate. In some areas there were perivascular pseudorosette-like structures. The histology showed round cells with hyper chromatic nuclei and pleomorphisms, eosinophilic cytoplasm, very frequent mitosis, apoptosis, and focal necrosis. The tumor showed diffuse, strong, cytoplasmic and membranous CD56, nuclear Fli-1 positivity. Multifocal staining for neuron specific enolase (NSE) and mesothelin and focal high molecular weight (HMW)+low molecular weight cytokeratin (CK), epithelial membrane antigen (EMA), synaptophysin (SYNP), WT1 positivity was detected (, ). The tumor cells were also positive for p53. CD99, chromogranin A, CD45, inhibin, calretinin, CA-125, ER, PR, CK7, CK20, Moc31, Tag72, myogenin, S100, and destine were negative. The surgical specimens of one ovary, appendix, and omentum were interpreted as Ewing sarcoma/PNET after immunohistologic and histologic studies. The patient was referred to the medical oncology department and chemotherapy consisting of vincristine, cyclophosphamide, and cisplatin was started. Radiotherapy was not applied. The CA-125 value was 84.4 U/mL before her first chemotherapy. The patient completed six chemotherapies after surgery. There was no evidence of disease after 7 months of follow-up.

Pemphigus vulgaris as the first manifestation of multiple myeloma: a case report
|
A 55-year-old Malagasy man, a doctor, a non-smoker of tobacco, with no significant past medical history, presented with bullous and erosive skin lesions involving his trunk and scalp for the past 2 months. No toxic exposure was noted. He had a family history of cancer; his mother and sister presented breast cancer and multiple myeloma, respectively, the diagnosis of which were delayed. He had no personal or family history of any autoimmune disease. No medication was prescribed prior to diagnosis. A physical examination revealed multiple crusted erosions intermixed with erythematosus patches over his scalp (Fig. ), trunk (Fig. ), and his back (Fig. ). He had no mucous membrane involvement. General physical and systemic examinations were normal.\nA complete blood count revealed microcytosis without anemia with mean corpuscular volume (MCV) of 76 fl and hemoglobin of 15.7 g/dL; his white cell count and platelet count were normal. Alanine and aspartate aminotransferase were normal (28 U/L and 25 U/L, respectively) but serum creatinine was high (121 umol/l; normal range: 53–115 umol/L). Other laboratory tests including corrected calcium level, phosphoremia, lactate dehydrogenase, and urine analysis were normal. His HIV status was negative.\nA skin biopsy showed suprabasal blisters containing eosinophils and acantholytic keratinocytes. Direct immunofluorescence of perilesional skin revealed immunoglobulin G (IgG) deposition in the intercellular spaces in the epidermis. In an enzyme-linked immunosorbent assay (ELISA), his serum autoantibody index against desmoglein-1 and 3 was found to be 112 RU/mL and 34 RU/mL (normal range, < 20 RU/mL), respectively. Serum immunoelectrophoresis showed a monoclonal gammopathy with a markedly elevated IgG level (2880 mg/dL) in association with a lambda free light chain. Urine analysis was negative for Bence-Jones protein and beta2-microglobulin was 2.4 mg/L. Bone marrow aspirate showed 6% plasma cell infiltration. Further investigations, including creatinine blood test and whole body radiographic examinations, showed that he had clinical stage I multiple myeloma of the IgG-λ type.\nAt first, the skin lesions regressed significantly after topical applications of corticosteroid ointment and no specific therapy for myeloma was conducted. Three months later, the dermal affliction occurred again so systemic administration of prednisolone (1 mg/kg per day) was started. Six months later, bone tomography revealed vertebral compression fractures of the thoracic and lumbar spine that correlated with our patient’s back pain topographically. However, his IgG level decreased (1080 mg/dL). Anti-myeloma treatment including melphalan and prednisone was started, which resulted in a rapid decline of monoclonal IgG concentration immediately. Skin and hematologic remission were maintained for 12 months.

Personalized prescription of tyrosine kinase inhibitors in unresectable metastatic cholangiocarcinoma
|
The patient is a 72-year-old man with histologically confirmed moderately differentiated intrahepatic cholangiocarcinoma (Fig. ). He was diagnosed in October 2015 with the following symptoms: moderate weight loss, pain in the right hypochondrium, loss of appetite and asthenia, with a Karnofsky scale index of 70%. MRI image at the time of diagnosis is shown on Fig. a. The tumor was not surgically removed because of advanced stage, multiple intrahepatic nodules and lung metastases.\nFour courses of chemotherapy (2 courses Gemcitabine in combination with Capecitabine and subsequent 2 courses Gemcitabine in combination with Cisplatin) were administered till May 2016. The treatment was poorly effective, and the tumor increased in size according to MRI (Fig. b); additional metastatic nodules appeared in the left and the right lobes with the spread to the bile duct, holedoch and into the gallbladder. Serum gamma glutamyltranspeptidase (GGT) level, which is associated with poor prognosis and tumor aggressiveness [, ], was significantly increased, when compared to pre-treatment levels (Fig. ). Karnofsky scale index decreased to 60%. As the patient did not respond to the best clinical practice treatment, we decided to switch the medication and considered TKI inhibitors as further treatment option. Taking into account available data on differential response of CCA patients to TKIs we performed advanced molecular analysis of the tumor to support our choice and identify the most effective drug.\nWe profiled gene expression in formalin-fixed, paraffin-embedded (FFPE) patient’s tumor biopsy sample, obtained at the time of the first CCA diagnosis. Briefly total RNA was extracted using Ambion’s RecoverAll™ Total Nucleic Acid Isolation. Complete Whole Transcriptome Amplification WTA2 Kit (Sigma) was used for reverse transcription and library amplification. Hybridization was performed according to CustomArray ElectraSense™ Hybridization and Detection protocol. Hybridization efficiency was detected electrochemically using CustomArray ElectraSense™ Detection Kit and ElectraSense™ 4X2K/12K Reader.\nWe next used bioinformatical software Oncobox to analyze gene expression data and to identify molecular pathways differentially regulated in the patient’s tumor sample []. Based on the abundance of gene transcripts for the molecular targets of anticancer drugs, Oncobox also makes it possible to generate a rating of target drugs potentially effective for the individual patients [, ]. Particularly, this analysis revealed that the ERK and Ras molecular signaling pathways were highly activated in the CCA patient’s tumor biopsy (Fig. ), the predicted rating of the most effective target drugs is shown in Table . Regorafenib, a multi-tyrosine kinase inhibitor was on the top position of the rating. However, there were no published studies of Regorafenib efficacy and tolerability in CCA. At the same time, several case reports demonstrated efficiency of TKI target drug Sorafenib for CCA treatment [–]. We, therefore, decided to use Sorafenib as the next line therapy and it was prescribed to the patient (800 mg daily) in May 2016. Treatment with Sorafenib coincided with the decrease of serum GGT level. MRI analysis in October 2016 revealed moderate tumor growth, corresponding to disease stabilization (Fig. c). However, additional nodules occurred slightly below the xiphoid process in the diaphragm area. Therefore, disease progressed according to RECIST criteria. And, importantly, after Sorafenib treatment, the patient did not complain of pain in the right hypochondrium. Before Sorafenib treatment the patient received Tramadol (100 mg im once a day) and Fentanyl (75 µg/h, Duragesic transdermal tape). After 1 month of treatment with Sorafenib the pain medication was switched to Ketoral (30 mg im twice a day). Considering all the above-mentioned facts it was decided to continue Sorafenib treatment. MRI performed in January 2017 revealed progression of tumor growth and additional nodule in the left lung (Fig. d). In addition, the following side effects occurred: redness, swelling, pain on the palms of the hands and soles of the feet. GGT level increased up to 319 U/L in December 2016.\nThe treatment regimen was next changed to Pazopanib, another TKI drug recommended based on the Oncobox rating. Sunitinib was not chosen because we attempted to eliminate the hand-foot syndrome, which occurred during Sorafenib administration. In the previous studies, Sunitinib treatment of CCA patients induced hand-foot syndrome in 43% of patients []. On the other hand, recent clinical trial of Pazopanib in combination with Trametinib in CCA did not report hand-foot syndrome as a side effect []. Pazopanib administration (800 mg daily) started since January 2017. The control MRI in July 2017 revealed progression in the lung nodes and 20% increase in sum of diameters of target lesions, which is a borderline between stabilization and progression according to RECIST (Fig. e). However, the change of treatment regimen resulted in elimination of Sorafenib side effects and general improvement of life quality. In addition, start of Pazopanib treatment coincided with a start of a trend towards decrease of serum GGT level (Fig. ). As for October 2017 (2 years after initial diagnosis), the patient was alive and physically active, with Karnofsky scale 80%. Our patient passed away due to the liver failure in November 2017.

Iatrogenic cerebral arterial gas embolism from flushing of the arterial line in two calves
|
A 7-day-old male Red Holstein–Friesian calf (No. 1) and a 28-day-old male Holstein–Friesian calf (No. 2) underwent respectively hot iron disbudding and sham disbudding in the context of a cross-controlled prospective clinical trial (ethical approval by Cantonal authority 2014_52_FR) investigating acute and chronic pain after disbudding. The procedure was standardized as following: after sedation with IM xylazine (0.1 mg/kg) an intravenous catheter was placed in a jugular vein and bilateral cornual nerve anesthesia (lidocaine 2%, 200 mg in total) was provided. In order to record physiologic nociceptive changes, heart rate (HR), respiratory rate (RR) and invasive blood pressure (IBP) were monitored during the procedure and hourly for the following 8 h. Prior to disbudding, an arterial cannula was placed in a caudal auricular artery and connected with the arterial monitor line previously filled with heparinized saline (100 IU/mL) from a fluid bag under 250 mmHg pressure. The bag was hanging vertically and only after verification that all parts were primed with fluids, the tubing system was connected to the arterial cannula. After zeroing the system at the height of the heart, to assess that the amount of damping was appropriate, the inline flushing device adjacent to the pressure transducer (Codan System DPT-6000, Codan Medical AG, Switzerland) was rapidly squeezed and released (fast flush test).\nBaseline IBP was 110/64/80 mmHg (SAP/DAP/MAP) and HR 79 beats per minute (bpm). Few seconds following the arterial flushing, IBP increased moderately (149/103/118 mmHg), and peak values were reached within 1 min (238/161/190 mmHg). During the hypertensive phase, HR first decreased slightly (68 bpm) and then increased up to 141 bpm. A short hyperpnoea (60 breaths per minute) was noticed. Concomitantly, the calf showed mild excitation, vocalization and purposeless movements, horizontal nystagmus and finally sensory depression. Over the following 10 min IBP decreased progressively to 166/126/141 and HR to 98. Disbudding was performed as foreseen. One hour later, sensory depression ameliorated and IBP returned to the baseline level. In the following 2 h a clinical improvement was observed, the calf could stand, yet it was reluctant to move. Four hours later, the calf could stand but right hemiparesis and severe ataxia were noticed and clear proprioceptive deficits on the right forelimb appeared. However, at that time, IBP, HR, RR remained in the baseline range. Neurologic examination revealed bilateral deficits of the V, VII and VIII cranial nerves. Sensory depression worsened progressively. An arterial blood sample taken 9 h after disbudding indicated mild hypoxemia (PaO2 = 78 mmHg with 0.2 FiO2), with normocapnia. Moderate hyperglycemia (6.6 mmol/L) was also present. When milk was offered, gag reflex was absent. Despite fluid and oxygen-supportive therapy during the night, the calf’ clinical conditions progressively worsened; the following morning, he was severely hemiparetic, stuporous and unable to drink. Blood gas and electrolyte analysis was unremarkable. Bilateral periocular edema and increased tension of the eye globe and opacity of the anterior chamber was noticed in the left eye (Fig. ). Menace response was bilaterally absent. Euthanasia was performed for ethical reasons.\nNecropsy revealed a mild, diffuse, acute anterior uveitis with occlusion of the filtration angle and glaucoma in the left eye. Multifocal petechiae were noticed on the skin. In both lungs, a severe alveolar edema was present with neutrophilic infiltration of terminal bronchioli and surrounding alveoli, interpreted as a mild acute bronchopneumonia. Multifocal perivascular edema was noticed in the heart. The brain was macroscopically normal, but the histological examination revealed bilateral, well demarcated, infarct-like areas of necrosis in the brainstem, which were most conspicuous ventrolaterally to the hypoglossal nuclei (Fig. ). These areas were characterized by edema, axonal swelling, neuronal eosinophilia and loosening of parenchyma with cavity formation. Small vessels within these areas had ill-defined and hypereosinophilic walls with necrotic endothelial cells (vessel wall necrosis) and contained degenerated neutrophils. Additionally, small infarcted areas were observed in the cerebellar vermis and in the cortex. Infarcts were associated with the presence of fibrin thrombi in small-sized vessels and capillaries and perivascular microhaemorrhages. These findings were interpreted as suggestive of disseminated intravascular coagulation (DIC).\nDespite that, no entry of air bubbles into the arterial cannula was noticed; we suspected retrospectively a retrograde cerebral arterial embolism as air was noticed in the distal part of the tubing system.\nAfter successful placement of the arterial line, the tubing system was filled with the inline flushing device adjacent to the transducer and carefully checked for the presence of air bubbles. Baseline rectal temperature was 38.8 °C. IBP was 115/58/78 mmHg and HR 109 bpm. Thereafter, a fast-flush test was performed, and some bubbles were noticed entering the arterial cannula under high pressure. The investigators (DC and AM) recognized later on that there was a partial disconnection of the luer-lock connector between the flushing system and the transducer. We hypothesized therefore the same mechanism for calf 1 (Fig. ). Few seconds after the inadvertent bubbles injection, the calf laid in lateral recumbency, showed excitation, hyperextension of the forelimbs, horizontal nystagmus and V and VII cranial nerve deficit. IBP pressure increased over 1 min up to 158/102/120 mmHg and concomitantly HR increased up to 128 bpm. The calf was repositioned in sternal recumbency, furosemide, 1 mg/kg, was injected IV and oxygen was provided. As the blood pressure increased further to 170/116/134, a second bolus of furosemide was injected (1 mg/kg IV). Over the next 2 min, IBP decreased to 153/92/112. HR decreased to 100 bpm and neurologic symptoms ceased. Sham disbudding was performed 1 min later when IBP was 138/74/95 mmHg and HR 98. One hour after disbudding, the calf was calm and still lying in sternal recumbency, but interactive. When encouraged, he could stand up without showing paresis. Blood pressure (115/60/80 mmHg) and HR (115 bpm) approached the baseline values. Slight hyperthermia (39.2 °C) was recorded. Respiratory rate remained in the normal range. No abnormalities were noticed in the following hours apart from slight hyperthermia (maximal peak 6 h later 39.6 °C). Behaviour and motor functions were deemed normal throughout the day; 8 h after disbudding, the calf showed normal temperature (38.8 °C) and normal appetite and it was reintroduced in the herd. The calf was observed for the following 3 months and it did not show either behavioral or neurological alterations.

Tocilizumab in Large Vessel Vasculitis – Different Routes of Administration
|
In a 71-year-old, female patient with GCA, MRI showed vasculitis of the abdominal aorta and both common iliac arteries. Response to methotrexate alone or combined with leflunomide, and cyclophosphamide was inadequate, upon which TCZ-IV was commenced. After two initial intravenous applications, TCZ was switched to TCZ-SC. Prednisolone was tapered to 5 mg within 4 months without symptoms indicating relapse. The patient relapsed after seven months, with cervical tenderness, signs of aortitis on MRI and vessel wall thickening of the carotid arteries (daily prednisolone dose at relapse: 5 mg). TCZ-SC was switched back to TCZ-IV, and prednisolone dose was increased to 30 mg with consecutive tapering. 3 months later, under 10 mg of prednisolone, wall thickening of the carotid arteries and of the aorta markedly decreased in CDU, and MRI respectively. The patient was free of clinical symptoms and remained in remission for 9 months (prednisolone dose 5 mg), until tocilizumab was stopped in preparation of valve surgery for progressive aortic regurgitation. 4 weeks after surgery, tocilizumab was restarted and prednisolone dose increased to 20 mg due to relapse (aortic histology, CRP).

Tocilizumab in Large Vessel Vasculitis – Different Routes of Administration
|
In a 47-year-old, female patient with GCA and anterior ischemic optical neuropathy, MRI and CDU showed halo and increased wall thickness of both ACC. Steroid-sparing treatment with methotrexate, leflunomide, and azathioprine had to be stopped due to toxicity. Intravenous cyclophosphamide (cumulative dose: 8000 mg) was ineffective. Therefore, TCZ-SC was started. Within 6 months prednisolone could be reduced to 5 mg, and CDU aspect became normal. After 10 months of TCZ-SC treatment, the patient relapsed with severe cervical tenderness responsive to prednisolone (daily prednisolone dose before pulse 5 mg). Therefore, TCZ-SC was switched to TCZ-IV. After a further follow up of 24 months, the patient is still in remission after tapering prednisolone to 3 mg with normal CDU.

Tocilizumab in Large Vessel Vasculitis – Different Routes of Administration
|
In a 21-year-old, female patient with TAK, CDU showed vessel wall thickening of both ACC, occluding the right one, of both internal and external carotid arteries, the left subclavian artery with occlusion, and the left vertebral artery with occlusion. She relapsed after 2 months of treatment with methotrexate and prednisolone, wherefore TCZ-SC was added and prednisolone increased from 15 to 100 mg. While tapering prednisolone in the following 4 months, the patient suffered two minor and one major relapse (severe cervical tenderness and progressive wall thickening in CDU), treated by prednisolone pulses. Prednisolone was increased from 15 mg to 100 mg and TCZ-SC was switched to TCZ-IV. Since the switch, no further relapse occurred during follow up of 20 months, and prednisolone could be tapered to 4 mg.

Spilled Gallstones Silent for a Decade: A Case Report and Review of Literature
|
A 78-year-old male with multiple comorbidities, including hypertension, hyperlipidemia, and type II diabetes mellitus, presented to our emergency setting with complaints of recurrent bouts of abdominal pain and fluctuating fevers for the previous two weeks. The patient reported that the pain is a new manifestation of a previously dull aching pain that had waxed and waned over the last decade. His description alluded to a pain that was sharp and intermittent with localization in the right upper quadrant. He could not attribute the intermittent nature of his predicament to any aggravating or relieving influences. The pain was associated with fluctuating low-grade fevers (99°F-100°F), anorexia, and an associated 13-pound weight loss, which culminated in a visit to our clinical setup.\nFurther interrogation disclosed that the patient underwent a laparoscopic cholecystectomy in 2003. The ensuing year was relatively pain-free but was followed by recurrent bouts of right upper quadrant pain, albeit less upsetting than his current presentation. He was subsequently diagnosed in 2005 with gallstone spillage. The patient chose conservative treatment for his abdominal pain, rather than invasive interventions, which included the administration of acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs). This treatment modality was sufficient for the duration of a decade. He presented to another medical facility with similar complaints of fever and abdominal pain in 2016. A computed tomography (CT) scan of his abdomen disclosed the presence of a necrotic phlegmon, which was subjected to aspiration. Its composition included a combination of fibrous material, granulation tissue, and inflammatory infiltrate. The aspiration provided considerable relief of symptoms and he was discharged on a gabapentin prescription that was well-tolerated and produced sustained amelioration of his pain, with only occasional wavering with respect to his baseline.\nThe initial assessment showed an elderly gentleman, who was alert and well-orientated but under considerable distress due to the abdominal pain and accompanying chills. He had a fever of 104°F, a heart rate of 120 beats per minute, a blood pressure of 95/70 mm Hg, and a respiratory rate of 19 per minute. An abdominal exam revealed a non-protuberant, soft, and tender abdomen with marked sensitivity in the right upper quadrant. He had perceptible bowel sounds, an absence of dullness on percussion, and a clear rectal vault. Pertinent initial laboratory investigations included an elevated white blood cell (WBC) count of 16,900/µL, C-reactive protein (CRP) of 6.5 mg/dL, and a random blood glucose (RBG) of 280 mg/dL. The patient subsequently underwent a whole body CT scan, which revealed a large 19-cm sub-diaphragmatic, right retroperitoneal abscess, which was inferior and posterior to the right hepatic lobe (Figure ).\nIn lieu of these findings, the patient was admitted and started on a combination of intravenous fluids, intravenous (IV) vancomycin and piperacillin-tazobactam due to an underlying suspicion of sepsis secondary to a hepatic and/or perihepatic liver abscess caused by a lack of gallstone retrieval following his cholecystectomy. He was subsequently subjected to a percutaneous CT-guided drain placement, which allowed for the evacuation of approximately 700 mL of grossly purulent material and provided prompt pain relief. The fluid sample was sent for a gram stain, culture, and a bilirubin assay. The gram stain of the abscess fluid revealed branching gram-positive rods concerning for Actinomyces, Nocardia, and Streptomyces; therefore, the patient remained on IV vancomycin and piperacillin-tazobactam, with the addition of trimethoprim-sulfamethoxazole (TMP-SMX) to the antibiotic regimen. Remarkably, the culture growth was positive for Propionibacterium and ampicillin-sulbactam was added to the list of antibiotics. Two days later, the patient was shifted to the intensive care unit (ICU) following unrelenting fever and persistent tachycardia, even after his abdominal drain placement was supplemented with vigorous antibiotic and antipyretic therapy. His ICU stay was complicated by episodes of dyspnea, tachypnea, and pleuritic chest pain, while a chest auscultation unveiled a decrease in breath sounds at the right basal region. A repeat CT scan confirmed the reduction in the size of the abscess and showed a new right-sided pleural effusion, which explained the patient’s breathing difficulties (Figure ).\nThe patient underwent an ultrasound-guided chest tube placement, which evacuated 10 mL of purulent fluid, followed by two doses of lytic therapy with tissue plasminogen activator (tPA) via the catheter. The following morning, he described an aggravation in his pleuritic chest pain, and an episode of shortness of breath, whereby, the oxygen saturation dipped to 90%. A new chest CT scan was ordered, which showed an interval increase in the right basilar opacity with a moderately sized pleural effusion (Figure ).\nHe was subsequently upgraded to a larger catheter via a CT-guided approach that evacuated a total of 900 mL of purulosanguinos fluid. The patient tolerated subsequent lytic therapies well and showed vast clinical improvement following this procedure, with a reduction in dyspnea, pleuritic chest pain, and fever, as well as a down-trending of his inflammatory markers.\nA repeat CT scan was performed on the 10th day of admission, which revealed a near-complete resolution of his right-sided pleural effusion, and a decrease in his right-sided retrohepatic intrabdominal abscess (Figure ).\nThe chest drain was removed and the patient was subsequently discharged with a transhepatic drainage catheter, daily intravenous ampicillin-sulbactam, and acetaminophen, as needed for pain control. The patient was shifted to oral amoxicillin-clavulanate a month after the resolution of his pain, fever, and stabilization of inflammatory markers. The transhepatic percutaneous drain was left in place in order to allow for the formation of a chronic drainage tract, with hopes of localizing the perpetrating gallstones at its base.\nTwo months after discharge, the patient underwent a procedure for upsizing the drain in order to accommodate for a choledochoscope into the abscess cavity and the maturing sinus tract. He subsequently underwent an abscess cavity endoscopy, whereby a catheter and scope were advanced into the cavity for exploration. An abscess catheter study was performed through the existing catheter and showed no filling defects, after which the catheter was removed and an endoscope was inserted for direct visualization of the main cavity, as well as the two “fingers” branching out of the abscess cavity. Two small stones were expelled after flushing the main cavity multiple times. Following the expulsion of the gallstones, a replacement catheter was advanced into the cavity and a second catheter study was performed to rule out the possibility of any other stones. The patient tolerated this intervention well and had no further drainage from the intra-abdominal drain.\nFollowing a lack of drain output and resolution of symptoms after his last endoscopic procedure a month ago, the patient's intra-abdominal drain was removed. The patient is currently stable and is being followed as an outpatient to date.

A Sub-acute Cerebral Contusion Presenting with Medication-resistant Psychosis
|
A previously healthy 24-year-old male presented to the emergency department with a head injury after falling 15 feet, and he was admitted with a diagnosis of a TBI to his right lateral frontal lobe. He was monitored for four days in the neurology intensive care unit and then discharged after improvement in symptoms. Three weeks from the initial injury the patient was brought into the emergency department by his family with symptoms like insomnia, atypical aggression, psychosis, and impulsive behavior. Upon arrival in the emergency department, the patient admitted to new onset suicidal and homicidal ideations with a plan to shoot himself and the (illusory) “friend who murdered his family and robbed his home” with a loaded gun in his possession. He admitted that two days prior to re-admission, he had become frustrated upon return to work, had not slept for 26 hours, and began damaging items around his house. He admitted to increased aggression, hallucinations, and paranoid ideations.\nThe patient, accompanied by his mother, denied any previous family or personal psychiatric history. His mother stated his personality had become increasingly impulsive and aggressive since his previous discharge from the hospital. The patient complained of worsening auditory and visual hallucinations, insomnia, headache, and visual floaters. The patient denied nausea, emesis, weakness, gait difficulty, and focal motor defects.\nThe patient had an unremarkable past medical history. Hypertension was diagnosed during his initial admission and he was started on lisinopril for management. Social history included intermittent alcohol and occasional marijuana use. He denied any tobacco or other illicit drug use. He lived with his parents, was in a monogamous relationship with his girlfriend, and worked in the construction field.\nUpon this admission three weeks postinjury, the patient presented with a blood pressure of 152/92 mmHg and a heart rate of 105 beats/minute. He was alert, oriented, anxious, and agitated. His five-digit forward recall was 4/5, and he was able to spell the word “WORLD” backwards and forward. The patient spoke with a normal rate and volume and without aphasia. Speech was coherent and goal-directed. Mood was anxious and affect-constricted. He had paranoid ideations with auditory and visual hallucinations. His heart had a regular rhythm without clicks or murmurs. Lungs were clear to auscultation bilaterally, and he had a soft and nontender abdomen with normoactive bowel sounds. Neurological examination revealed cranial nerves II-XII were intact bilaterally. Patient had 5/5 strength bilaterally without pronator drift. No pathological reflexes were noted.\nUpon chart review, a two-week routine follow-up CT after his initial injury revealed increasing cerebral edema on the right parietal lobe with no increasing mass effect or midline shift (Figure ). It also noted a nondisplaced fracture of the right temporoparietal region that was not commented on prior imaging.\nOn day one of this admission, three weeks postinjury, the patient’s electroencephalography was unremarkable, and an MRI showed several acute/subacute cerebral contusions within the right frontotemporal region; with progression of the temporal lobe contusion (Figure ). It showed mild associated perifocal edema without significant mass effect or midline shift. Four days later, a second MRI of the brain showed no significant changes. A third brain MRI was taken after the patient accomplished a full night’s rest and psychotic symptoms had resolved (Figure ). This MRI showed a persistent dominant focus in the right temporal region that was well demarcated and stable in size. It showed resolving white matter edema and improving post-traumatic foci of altered signal intensity when compared with prior imaging.\nA multi-disciplinary team was consulted which included a hospitalist, neurologist, neurosurgeon, psychiatrist, occupational therapist, physical therapist, and speech therapist. Upon this admission, the patient suffered from fluctuating auditory and visual hallucinations, anxiety, headaches, and agitation. He was started on dexamethasone, valproic acid and lorazepam, which did not alleviate his psychosis. Throughout the hospital admission, the patient reported some insight and memory to these symptoms; yet, he reported being unable to control them. Although he could recall all the events, at times he was unable to differentiate between reality and the hallucinations. Throughout the next week, a new medication was incorporated into his regimen daily to help induce sleep. These medications included high-dose trials of zolpidem, hydroxyzine, quetiapine, and olanzapine. The patient was finally able to accomplish rest with the combination of 20 mg intramuscular (IM) ziprasidone and 2 mg IM lorazepam on the seventh evening. After one night of sleep the patient was alert, oriented, cooperative with normal mood and affect. The following morning postsleep, his hallucinations and psychosis ceased completely. A few days later he was discharged to his home under family supervision with scheduled outpatient TBI rehabilitation to follow.

Pauci-immune Glomerulonephritis in Systemic Lupus Erythematosus (SLE)
|
A woman in her late 30s, with a history of SLE characterized by positive anti-nuclear antibodies, anti-Smith antibodies (1:160), anti-double-stranded deoxyribonucleic acid (anti-dsDNA) antibodies (> 1:640), anti-ribonucleoprotein (anti-RNP) antibodies, lupus anticoagulant, immunoglobulin M (IgM) anti-cardiolipin antibodies (27, normal: 0 - 12 U/ml), hypocomplementemia (C3 < 40, normal: 90 - 165 mg/dl; C4 < 8, normal: 10 - 40 mg/dl), rheumatoid factor of 50 IU/mL (negative: < 13.9), elevated erythrocyte sedimentation rate (ESR), arthritis, lymphopenia, and thrombocytopenia, presented to our clinic with new proteinuria (spot urine protein/creatinine ratio 1,059 mg/g) and a normal creatinine (0.6 mg/dl). Evaluation for antibodies of perinuclear (p)-ANCA, cytoplasmic (c)-ANCA, and atypical p-ANCA were all negative. She underwent a renal biopsy that demonstrated focal, mild necrotizing crescentic glomerulonephritis. Glomerular staining showed non-specific 1+ linear staining of the glomerular basement membrane and rare 1+ granular mesangial staining for IgG, IgM, and kappa but with negative staining for immunoglobulin A (IgA), C3, C1q, and lambda. Taken together, this renal biopsy was summarized as a pauci-immune focal necrotizing/extracapillary proliferative glomerulonephritis. The patient was treated with rituximab, mycophenolate mofetil (3g daily), and prednisone but continued to demonstrate proteinuria with 0.73 g/24 hours, creatinine of 0.7 mg/dl, and no hematuria. She underwent a second renal biopsy (at a time when serologies demonstrated low C3 at 77 mg/dl and positive anti-dsDNA antibodies), which resembled class II lupus nephritis with limited subcapsular glomerular sample with deposits staining for IgG, IgM, kappa light chain, and C3, along capillary loops and peripheral mesangium with sparse deposits on electron microscopy. Given the concerns for steroid side effects, a change in insurance, and the lack of follow-ups, she was maintained on mycophenolate mofetil, 3g daily, and a low dose of prednisone, 5 mg, along with lisinopril. However, she continued to experience prolonged morning joint stiffness and her hand MRI demonstrated synovitis. Adding methotrexate led to significant improvement in her arthritis. By 23 months after the initial renal biopsy, she continued to have proteinuria, intermittently low C3, and positive anti-dsDNA antibodies and underwent a third renal biopsy. This biopsy, similar to the first sample, demonstrated a pauci-immune focal proliferative segmental crescentic/necrotizing lesion in 30% of the glomeruli. On repeat serologic testing, her c-ANCAs, p-ANCAs, and atypical ANCAs were still negative.

Parkinsonism in a Patient with Human T-lymphotropic Virus 1 Myelopathy
|
A 71-year-old female with the history of HTLV-1 infection for 20 years, congestive heart failure, coronary artery disease, hypertension, diabetes type-2, peripheral vascular disease, chronic neck and back pain, nonambulatory for a year admitted to the medical service as dehydration and acute kidney injury. Neurology was consulted for worsening weakness and pain in the legs with paresthesia as well as evaluation for HTLV-1 myelopathy with pain, stiffness and gait problems. Neurological examination showed flat, mask-like face with a positive glabellar reflex. She was noted to have decreased power bilaterally in upper and lower extremities with brisk reflexes and hypertonia. Motor examination of upper extremities showed a strength of 4 x 5 with brisk reflexes and also noted to have resting as well as intention tremor. Lower extremity muscle power was 2 x 5 with brisk reflexes and bilateral clonus and bilaterally upgoing toes. Sensory examination was normal with generalized diffuse rigidity. Her workup included computed tomography (CT) scan of the brain showing bilateral basal ganglia calcifications and mild cortical atrophy, magnetic resonance imaging (MRI) brain T2W image demonstrating low signal intensity from iron accumulation in the red nucleus, and substantia nigra and atrophy of the cerebral cortex and superior vermis of the cerebellum (Figure ). MRI C-spine, MRI of the thoracolumbar spine and magnetic resonance angiogram (MRA) were unremarkable. Serum HTLV-1 antibody was positive by enzyme immunoassay (EIA) and glutamic acid decarboxylase (GAD65) antibody was also positive at 8 IU/ml by enzyme-linked immunosorbent assay (ELISA). The clinical evaluation was suggestive of HTLV-1 related myelopathy with parkinsonism and patient was started on a trial of baclofen and Sinemet® (carbidopa-levodopa).

Betel Chewing and Nonalcoholic Steatohepatitis
|
A 31-year-old Asian American female with past medical history of chewing of betel leaf with betel nuts and non-smoker, who immigrated to the USA from Burma four years previously, was referred to the Digestive Health Center at the University of Virginia for evaluation of elevated transaminases discovered upon routine testing. She reported no previous history of liver test abnormality or liver disease. She was not using any hepatotoxic prescription or over the counter medications or supplements and reported rare consumption of alcohol. Besides, she had no family history of liver disease, hepatocellular carcinoma, autoimmune disorders or diabetes mellitus.\nThe physical examination was significant for obesity with weight 66 kg, height 146 cm, body mass index (BMI) 31, hepatomegaly, nonpalpable spleen, and lack of stigmata of chronic liver disease. Extensive laboratory workup revealed normal complete blood count, renal function, serum electrolytes, iron studies, serum immunoglobulin levels, and ceruloplasmin. Also, hepatitis B and C serologic tests and autoimmune markers were negative. Fasting lipid profile revealed dyslipidemia (total cholesterol 260 mg/dL, triglycerides 267 mg/dL, high density lipoprotein 45 mg/dL, and low density lipoprotein 170 mg/dL). Fasting blood glucose was 165 mg/dL with simultaneous fasting insulin level of 4.8 mill international units/liter and a homeostasis model assessment of insulin resistance score of 2.9, thus has insulin resistance. Hemoglobin (Hgb) A1c level at this time was 6.8% which was higher than previous values from eight months prior (6.1%), 16 months prior (6.1%) and 39 months prior (4.8%).\nUltrasonographic evaluation of the abdomen revealed hepatomegaly, hyperechogenic liver indicative of severe hepatic steatosis, an ill-defined liver mass, and standard spleen size. Magnetic resonance examination defined the liver mass as hemangioma in addition to hepatomegaly and severe hepatic steatosis. Ultrasound-guided liver biopsy (sample size of 3.5 cm) showed severe macrosteatosis with mild lobular and periportal inflammation associated with focal hepatocyte damage (Figure , Panel A). Trichrome staining revealed focal portal, periportal and perisinusoidal fibrosis consistent with stage II (Figure , Panel B) with a NASH activity score (NAS) of 7. The patient was instructed to exercise routinely and follow a healthy diet. She was seen in follow-up for three months at which time her weight was unchanged. Physical examination revealed dark brownish red pigment on the teeth, tongue, and oral mucosa. Upon questioning the patient about this finding, she admitted to chewing betel on an average of 10 times per day for the last eight years. The patient reported an associated weight gain of around 16 kg from her baseline weight maintained for many years at 50 kg (BMI 23.5). This significant weight gain could not be reversed despite daily physically demanding work and following a healthy diet recommended by her primary care physician.

A Rare Cause of Chest Pain
|
A 59-year-old male with no significant past medical history presented to the emergency department (ED) with a sudden onset of chest pain and shortness of breath that had begun while he was eating dinner. The physical examination was unremarkable, including the chest examination, except that the patient remained quite anxious. A blood sample analysis was within the normal range, including troponin. The electrocardiogram (EKG) was unremarkable. A plain chest radiograph did not show any abnormality. A computed tomography (CT) scan of the neck revealed a 2.5-cm long rectangular prism-type bone, horizontally lodged in the esophagus at the level of the aortic arch (cervical vertebra 7-thoracic vertebra 1, as shown in Figure ). Because the patient was symptomatic and the CT neck scan showed the presence of a sharp, pointed bone, esophagogastroduodenoscopy (EGD) was performed under general anesthesia, which involved the retrieval of a piece of bone from the upper esophagus just below the upper esophageal sphincter (Figure ). The foreign body was removed with the help of queen retrievers (Figure ). The patient did well after the removal of the foreign body and did not suffer a recurrence of the prior chest pain. He was discharged home on proton pump inhibitors.

Trigeminal neuralgia associated with ophthalmic surgery: a case series
|
A 63-year-old Caucasian man, a dentist, was referred by another professional with an epiretinal membrane and cataract in his left eye. His medical history revealed he had hypertension for the past 6 years under treatment. He had no relevant history of eye problems. His visual acuity test was 20/30 in his left eye. An ophthalmologic examination of his left eye revealed a nuclear cataract ++, epiretinal membrane with microfolds, and macular edema confirmed by a macular optical coherence tomography (OCT) scan. Phacovitrectomy was performed in his left eye under general anesthesia. On postoperative day 1, he did not experience pain and his visual acuity was 20/50. The findings included: a corneal edema, well-positioned intraocular lens, and Tyndall +. A fundoscopy showed an attached retina. On postoperative day 7, he did not experience pain and visual acuity was 20/20. The pseudophakia was unremarkable and an attached retina, without an epiretinal membrane, was observed on the fundoscopy. On postoperative day 20 he was admitted to an emergency ward due to severe eye pain that woke him up in the middle of the night. He described it as a severe, paroxysmal, lancinating facial pain and rated it as a 10/10 lasting 10 to 30 seconds. It radiated to the distribution of the first division of the right trigeminal nerve. He denied contralateral pain. On physical examination, he was neurologically intact. No family history of neurological problems was found. His visual acuity was 20/20. Pseudophakia and nasal choroidal detachment were observed. After consultation with specialists from the anesthesia and neurology departments, he was diagnosed as having TN with ophthalmic branch involvement. A complete blood count (CBC) test and liver function test were ordered and the results were unremarkable. Normal findings on both CT and MRI were reported. Treatment with tramadol and morphine was started. A good response to medical treatment was observed. He had some episodes of TN during the first 2 months. After 1 year of follow-up, he did not have any more episodes of TN.

Trigeminal neuralgia associated with ophthalmic surgery: a case series
|
A 38-year-old Caucasian man, a mechanic, presented at the Ophthalmology unit of Sanatorio Mapaci with a perforating wound in his right eye. He had no relevant past medical/family history or eye problems. Visual acuity was hand motion in his right eye. Slit lamp biomicroscopy showed a penetrating wound in the cornea between hours 3 and 7, anfractuous injury, iris prolapse, and grade IV hyphema. There was no visualization of the posterior segment structures. Primary closure of the cornea with removal of the necrotic iris was performed on the same day under general anesthesia without a nerve block. On postoperative day 1 he did not experience pain and his visual acuity was light projection; IOP was 6 mmHg. The corneal wound was sealed with seven stitches (10/00 nylon sutures), Seidel test was negative, and hyphema was grade IV. He made good progress during the following days. On postoperative day 6 he was admitted to an emergency room due to severe pain in the right side of his face activated by numerous facial stimuli. He described it as disabling lacerating pain and rated it as a 10/10. A neurological examination was unremarkable. On a visual acuity test, he was able to count fingers at 10 cm. Slit lamp biomicroscopy showed a sealed corneal wound and grade III hyphema; IOP was 16 mmHg. He was referred to a medical clinic and underwent anesthesiology, where he was diagnosed as having TN. Blood tests including CBC and liver function test were normal. Normal findings in both CT and MRI were reported.\nTreatment with tramadol, pregabalin, and B12 complex was started; during the first 2 months of medication he lost 9 kg (20 pounds) from not eating for fear of exacerbating the pain. Chlorpromazine and carbamazepine were added and his course evolved with sporadic pain.

Trigeminal neuralgia associated with ophthalmic surgery: a case series
|
A 52-year-old Caucasian man, a construction worker, was referred 15 days after suffering a blunt trauma to his right eye. His visual acuity was no light perception. An ophthalmologic examination revealed a clear cornea, traumatic mydriasis, aphakia, and Tyndall +++. The findings included: intraocular pressure (IOP), 40 mmHg; a pale optic disc with well-defined edges; temporal retinal necrosis; and an intumescent crystalline lens at hour 6. Vitrectomy was performed to remove the crystalline lens. On postoperative day 1, he did not experience pain. The findings included: visual acuity; no light perception; traumatic mydriasis; aphakia; Tyndall ++; IOP, 12 mmHg; and temporal retinal necrosis. On postoperative day 7, he was admitted to an emergency room with severe and excruciating pain in the right side of his face, predominantly in his right eye. After consultation with specialists from the anesthesia and neurology departments, he was diagnosed as having TN, with ophthalmic branch involvement. Blood tests were unremarkable. Normal findings on both CT and MRI were reported. He reported that Valsalva’s maneuver triggered pain. Treatment with tramadol, pregabalin, and B12 complex was started. A good response to medical treatment was observed.

Mosaic Tetrasomy of 9p24.3q21.11 postnatally identified in an infant born with multiple congenital malformations: a case report
|
The proband was a preterm newborn boy, the first child of non-consanguineous parents, born at 31 weeks gestation to a 44-year old father and a 43-year old mother by cesarean section. At birth, the child weighed 1,480 g, measured 44 cm in crown-to-heel length, and exhibited multiple congenital anomalies. The newborn was transferred to the Intensive Care Units (ICU) immediately after birth. His general health condition deteriorated progressively, leading to his death at 105th days after birth. The newborn had brain malformation, including ventriculomegaly and corpus callosum dysgenesis, cleft lip and palate, retrognathism, hypertelorism, clenched hands with overlapping fingers, and hypotonia. Additionally, he revealed mild heart septal hypertrophy, ambiguous genitalia, enlarged kidneys without corticomedullary differentiation, and gallbladder with tiny cystic formations (Fig. ). His mother had three miscarriages from previous marriages and one miscarriage with her current husband. The remaining of his family history was otherwise unremarkable.\nBoth parents signed a written informed consent and the mother signed as the legal representative for the child. Peripheral blood was obtained to isolate genomic DNA for CMA using Qiagen QIAamp® DNA Mini kit (Hilden, Germany). Karyotyping was performed in a private laboratory through conventional cell culture, harvesting, and GTG banding with a > 550 bands resolution following standard procedures []. Chromosome analyses were done using Zeiss Axio Scope (Jena, Germany) and the software IKAROS® (Metasystems Corporation, Altlussheim, Germany). All laboratory procedures were carried out following international standardized protocols and consensual criteria of quality.\nThe CMA was carried out on proband and his biological parents using the GeneChip® CytoScanHD™ (Affymetrix, Santa Clara, USA) following the manufacturer’s recommendations without modifications. Chromosomal analyses were done using the Chromosome Analysis Suite (ChAS®) software (Affymetrix, Santa Clara, USA) and the CNVs found in the patient were analyzed in comparison with public databases, including Database of Genomic Variants (DGV), Database of Chromosomal Imbalance and Phenotype in Humans using Ensemble Resources (DECIPHER), and CytoScanHD™ Array Database. Furthermore, CNVs were classified according to their nature, based on [, ].\nThe proband showed a male karyotype with a large submetacentric SMC in 90% of the analyzed metaphases after counting 50 metaphase spreads. His karyotype was 47,XY,+mar[45]/46,XY[5], suggesting 10% mosaicism. The parental karyotypes and CMA results had no visible numerical or structural alterations. The proband’s CMA revealed the marker chromosome corresponded to a de novo 70.77 Mb gain at arr[GRCh37] 9p24.3q21.11(203,861_70,974,662)× 4[0.3] dn with 30% mosaicism, encompassing 286 genes, including 152 OMIM morbid genes (Fig. ).

Inflammatory myofibroblastic tumor of the pleura with adjacent chest wall invasion and metastasis to the kidney: a case report
|
A 76-year-old Korean man presented with upper back pain for 2 months and motor weakness in both lower extremities for 2 days. A chest radiograph and computed tomography (CT) performed at another institution showed a pleural mass in the upper lobe of his right lung. He was referred to our hospital for evaluation of the pleural mass and paraplegia. He had been treated with medication for 4 years for type 2 diabetes mellitus and primary hypertension. He did not have a family history of malignant disease. On chest examination, he had tenderness at the level of the fifth rib on the right side. On neurologic examination, he showed paraplegia with numbness and a sensory deficit below the T5 dermatome.\nLaboratory findings showed an elevated C-reactive protein level of 6.84 mg/dL (normal range, 0.0–0.3 mg/dL), blood urea nitrogen of 25 mg/dL (normal range, 7.8–22.0 mg/dL), and a serum creatinine of 1.5 mg/dL (normal range, 0.6–1.4 mg/dL). Urine analysis showed 4+ blood, with many red blood cells and 0–1 white blood cells/high-power field (Table ).\nA chest radiograph showed a large homogenous opacity in the right superior mediastinum. Contrast-enhanced chest CT showed a 7.3 cm × 4.4 cm × 7.7 cm heterogeneous pleural mass involving the right fifth rib and vertebral body (Fig. ).\nContrast-enhanced abdominopelvic CT showed a mass infiltrating the right renal hilum without vascular occlusion or hydronephrosis (Fig. ). Spine CT and enhanced magnetic resonance imaging (MRI) showed a large pleural mass in the right paravertebral area at the level of T3 to T6 (Fig. , ). CT-guided percutaneous needle biopsy of the pleural mass was performed.\nHistological findings on hematoxylin and eosin (H&E) staining showed proliferation of spindle cells with infiltration of lymphocytes and plasma cells (Fig. ). Immunohistochemistry showed neoplastic cells positive for CD68, focally positive for smooth muscle actin (SMA), and negative for cytokeratin and desmin (Fig. ). IMT was diagnosed based on the histological examination.\nAs the tumor could not be completely resected, treatment with glucocorticoids (methylprednisolone 1 mg/kg) and radiotherapy (5 days/week for 3 weeks at 3 Gy/fraction, 45 Gy/15 days) was started. After 1 month, laboratory findings were unremarkable. Hematuria, which is thought to be caused by kidney metastasis of IMT improved after treatment (Table ). Chest CT showed reduction in the size of the pleural mass (6.0 cm × 1.8 cm × 5.3 cm) and abdominopelvic CT showed decreased infiltration around the right renal pelvis (Fig. ). The summed-up diameters of both target lesions decreased from 121 mm to 91 mm, that is, a 24.8% reduction of baseline diameter. According to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria it could be defined as stable disease. He was discharged on orally administered glucocorticoids and showed improvement in symptoms on follow-up 1 month after hospital discharge. Since then, however, he has not attended a follow-up visit.

Second Trimester Cervical Ectopic Pregnancy and Hemorrhage: A Case Report and Review of the Literature
|
Index patient is a 28-year-old gravida 1 para 0 at 12 weeks and 3 days gestational age by the last menstrual period who presented for routine first trimester aneuploidy screening. During nuchal translucency ultrasound, pregnancy noted to be located within the cervix, specifically, 8mm from the external cervical os (). Fetal heart rate was 168 at this time and there were no notable fetal anomalies. Patient denied vaginal bleeding or pain. She denied any history of gynecologic surgery. Findings were subsequently confirmed by magnetic resonance imaging (MRI) (). The MRI showed a 6.5 x 4 x 5cm amniotic sac with embryo located within the cervix. Sterile speculum exam revealed no visible pregnancy tissue from os but enlarged and edematous cervix. HCG was 68,350 mU/mL at this time.\nGiven the proximity to cervical vasculature, the risk of life-threatening hemorrhage was very high. A multidisciplinary team including Reproductive Endocrinology, Maternal-Fetal Medicine, Gynecologic Oncology, and Interventional Radiology reviewed the case. At 12 weeks and 6 days gestational age, the patient was admitted to Special Delivery Unit (SDU) at the Cleveland Clinic.\nUterine artery embolization (UAE) under conscious sedation was performed with Gelfoam suspension in contrast until each uterine artery was embolized to stasis and confirmed by angiogram. Procedure was well tolerated and fetal heart rate was monitored before and after the procedure, per institutional policy. Initially the fetal heart rate was low and then not present after the procedure. Patient was then given weight-adjusted intramuscular methotrexate. On day 4 after MTX injection, patient remained asymptomatic with HCG of 19,795 mU/mL. Day 7 after MTX injection, HCG was 14,765 mU/mL. Patient was discharged on hospital day 11.\nOn postoperative day #14 after UAE, patient represented. Patient was febrile, with nausea/vomiting and with profuse vaginal bleeding. HCG at this time continued to show downtrend at 3360 mU/mL. Patient was taken to the operating room for dilation and curettage (D&C). Uncomplicated ultrasound-guided suction and sharp D&C were performed. Postoperatively, patient was febrile and tachycardic with evidence of pulmonary edema and acute vaginal blood loss. Patient was transferred to the intensive care unit for severe sepsis and acute kidney injury. Sepsis treated aggressively with vancomycin, clindamycin, and piperacillin-tazobactam and furosemide diuresis with clinical improvement. Antibiotics narrowed to renal-dosed piperacillin-tazobactam and then ampicillin-sulbactam. Patient was discharged in stable condition with IV antibiotic regimen. Patient was seen 2 weeks after discharge; kidney injury had resolved as well as vaginal bleeding; HCG was negative.

When the Benign Pneumatosis Intestinalis Becomes No Longer Benign: A Rare Case of Bowel Perforation in a Patient with Systemic Sclerosis
|
A 78-year-old woman with a long-standing history of anti-centromere antibody positive systemic sclerosis with limited skin involvement (CREST syndrome) initially presented to emergency room (ER) for a one-day history of hematemesis and mild abdominal pain. Her medical history was remarkable for peripheral artery disease and duodenal arteriovenous malformation. At presentation, her vital signs were within normal limits and her physical examination revealed mild periumbilical tenderness and decreased bowel sounds without significant signs of peritonitis. Laboratory studies revealed a WBC count of 29X10 ∧3/μl and a hemoglobin of 4.7 g/L which acutely declined compared with her baseline hemoglobin of 9.5 g/L. Renal/liver function tests were within normal limits. Elevated venous lactate level was noted. Patient received intravenous fluid resuscitation and empirical piperacillin/tazobactam as well as 2 units of red blood cells transfusion in ER. A subsequent computed tomography (CT) scan of the abdomen that showed significantly dilated colon and pneumatosis intestinalis (). No surgical intervention was deemed necessary per general surgery consultation, considering that the pneumatosis intestinalis was stable compared to the previous CT findings two years ago and the absence of acute peritonitis sign. Patient was then admitted to ICU for close monitoring and management of acute on chronic anemia from GI bleeding. Urgent esophagogastroduodenoscopy (EGD) only identified Barrett's-type esophageal mucosa, erosive gastritis without actively bleeding lesion. Patient was discharged home on the 4th day of hospitalization after tolerating liquid food. However, she was brought back to ER for severe lower abdominal pain just a few hours after discharge. The abdominal pain was sharp, constant, and nonradiating. No melena or hematochezia was reported. On examination, absent bowel sounds and abdominal distention without rebound tenderness or guarding were noted. Her laboratory evaluation was significant for leukocytosis and hypokalemia. Repeated CT scan of abdomen/pelvis showed distended small and large bowel loops, portal venous gas, and pneumatosis within the jejunum and colon (). Clinical diagnosis of bowel perforation was made, for which patient underwent emergent exploratory laparotomy. Patchy necrosis throughout the large intestine and a perforated lesion in the ascending colon were identified during the operation. Subtotal colectomy, omentectomy, and end ileostomy were performed. Pathological findings were consistent with colonic perforation with transmural ischemic necrosis and fibrosis (). CT angiography and conventional angiogram were performed to determine the culprit artery for bowel ischemia and identified a noncritical stenosis in superior mesenteric artery (). Patient was then transferred to ICU for postoperative care. Patient's recovery was complicated with ventilation dependent respiratory failure and another episode of bowel perforation. Given her advanced age, comorbidities, and poor prognosis, end-of-life care was discussed with family members, and they decided to initiate comfort care after a prolonged hospital stay.

Coronary Artery Ectasia Presenting as a Non-ST Elevation Myocardial Infarction in a Young Adult: Case Presentation and Literature Review
|
A 26-year-old African-American gentleman presents to the emergency department with pressure-like retrosternal chest pain that occurred one hour after he completed a workout. His pain subsided after ingestion of an antacid. He has no known medical history and takes no medications. He is a current smoker with a pack-year index of 22. He smokes marijuana but denies other illicit drug use. Both his father and grandfather had hypertension, diabetes, and peripheral arterial disease requiring limb amputation, but there was no known family history of coronary artery disease.\nEKG revealed a right bundle branch block with no ST segment or T wave changes indicating ischemia. Initial troponin level was elevated at 8 ng/ml (normal range: <0.03 ng/ml). The patient refused to be admitted for further evaluation and left the hospital against medical advice. He returned a week later, with no symptoms, only to complete the evaluation of his prior episode of chest pain. Echocardiography revealed akinesis in the basal and inferior walls with an ejection fraction of 50%. Coronary angiography revealed moderately to severely dilated aneurysms in the proximal segments of the left anterior descending, left circumflex, and right coronary arteries without flow-limiting lesions ().\nThe patient had no recollection of any febrile childhood illness that would be consistent with childhood Kawasaki disease. He was discharged on dual antiplatelet therapy and a high-intensity statin, as well as metformin for a new diagnosis of prediabetes.

Purpura Fulminans and Septic Shock due to Capnocytophaga Canimorsus after Dog Bite: A Case Report and Review of the Literature
|
An 80-year-old woman was accompanied by her son at the emergency department (ED) of our hospital because of progressive altered mental status and persistent high fever in the previous 48 hours. The patient had medical history of depression in treatment with bromazepam and olanzapine. At the ED evaluation, patient was conscious and alert with stable respiratory and hemodynamic conditions and fever (39°C) and mild abdominal pain without defensive reaction. Laboratory tests showed only an increased C-reactive protein (6,1 mg/dl). Abdomen ultrasound showed signs of previous cholecystectomy and a slight dilatation of biliary tree. Two hours later, the patient became progressively drowsy, cyanotic, and mottled on chest and lower extremities despite stable hemodynamic parameters. Arterial blood gas analysis (ABG) revealed mild hypoxia and hypocapnia. Blood and urine samples were collected for microbiological cultures before starting empiric therapy with piperacillin-tazobactam (loading doses 4, 5 g, and 18 g/day continuous infusion). Patient underwent chest and abdomen computed tomography (CT) that showed extended ground-glass area in basal lobes bilaterally () and hypoperfusion in liver, spleen, and kidneys and dilatation of intra- and extrahepatic biliary tree.\nAt the end of CT scan, the patient was transferred to the Intensive Care Unit (ICU) because of severe respiratory failure. At ICU, admission patient was unconscious (Glasgow Coma Scale (GCS) 3/15), hypoxic (SpO2 88% with FiO2 60%), and hypotensive (100/50 mmHg). At physical examination, we observed petechiae and purpura on her trunk and her skin was grayish and mottled (). ABG analysis showed a severe metabolic acidosis with lactate 16 mM. The patient became extremely hypotensive and after aggressive fluid resuscitation (40 ml/kg crystalloides) we started norepinephrine (up to 0,2 mcg/Kg/min). Hemodynamic measurements by pulmonary artery catheter revealed a low cardiac Index (CI) (1,3 L/min/m2). Echocardiography showed a severe depression of left ventricle ejection fraction without segmental akinesia and, thus, we started dobutamine infusion that after 2 hours was switched to levosimendan because of severe tachycardia without CI improving. At ICU admission, the patient showed severe leukopenia (610/mmc), thrombocytopenia (8000/mmc), and low levels of immunoglobulins (IgG 392 mg/dl, IgA 111 mg/dl and IgM 16 mg/dl); aPTT was undeterminable and INR was prolonged (2,79). Renal and hepatic functional indexes worsened compared to ED first evaluation with a total SOFA score of 22; troponin was high (847 ng/l) as well as procalcitonin (115 ng/ml). The severe hypotension and hyperlactatemia (17 mM) refractory to vasopressors, steroids, and inotropes led us to initiate blood purification (Cytosorb, CytoSorbents Europe GmbH, Germany) as rescue therapy 8 hours after admission. Despite aggressive therapies, cardiac arrest unresponsive to resuscitation maneuvers occurred 4 hours later.\nDuring an extended interview with patient's family members some hours after ICU admission, an important anamnestic element was revealed: 3 days before hospital admission the patient was bitten by a dog, getting a small lesion on the fourth finger of the right hand. Two days after patient's death, the microbiological laboratory reported a blood culture positive for C. canimorsus sensitive to any tested antibiotic class. No other microorganisms were identified in the samples evaluated (rectal swab, skin lesions swab, bronchial secretion, urine, Legionella and Streptococcus pneumoniae antigens, CMV-DNA, and B-D-glucan).

Venetoclax in Combination with Decitabine for Relapsed T-Cell Acute Lymphoblastic Leukemia after Allogeneic Hematopoietic Cell Transplant
|
A 20-year-old male with no past medical history presented with acute hypoxic respiratory failure requiring intubation. CT scans revealed a 9.1 × 7.3 cm mediastinal mass encasing the aortic arch with extension into the lower neck resulting in tracheal deviation. Laboratory evaluation demonstrated a white blood cell count of 2.5 × 109/L with 78% blasts on differential, hemoglobin 7.1 g/dL, and platelets 51 × 109/L. Bone marrow evaluation revealed a hypercellular marrow with 98% blasts by morphology. By flow cytometry, blasts expressed CD34, CD117, CD33, CD38, CD56, and CD7 and lacked expression of myeloperoxidase (MPO) and monocytic markers. A subset of blasts expressed low levels of cytoplasmic CD3 although subsequent assessment by immunohistochemistry for CD3 was negative. The blasts were negative for CD2, CD4, CD5, CD8, CD19, and cCD79a. Cytogenetic analysis revealed 10 metaphases with a complex karyotype including rearrangement of chromosome 4, loss of chromosomes 12 and 13, and a rearrangement between chromosome 13 and 1-2 unidentified markers. Molecular testing was positive for a FLT3-ITD mutation. A fine needle aspiration of the mediastinal mass demonstrated acute leukemia with an immunophenotype similar to that of the bone. T-cell gene rearrangement analysis by PCR on the mediastinal biopsy showed no evidence of clonal T-cell gene rearrangement. While it was difficult to assign a definite lineage for this acute leukemia, diagnostic considerations included acute myeloid leukemia (AML), T-ALL, and mixed phenotype acute leukemia T/myeloid (MPAL). To meet criteria for MPAL T/myeloid, blasts must express lineage-defining markers for both T and myeloid lineages []. This acute leukemia lacked MPO as well as monocytic markers and therefore did not meet criteria for the myeloid component of MPAL T/myeloid. While flow cytometry demonstrated weak cytoplasmic CD3 on the blasts suggestive of T-lineage differentiation, this could not be confirmed by immunohistochemical stains. Additionally, the blasts lacked expression of CD2, CD4, CD5, CD8, and CD1a. Therefore, a diagnosis of AML, NOS was initially favored.\nThe patient was induced with daunorubicin in combination with high-dose cytarabine and achieved complete remission (CR). He was consolidated with 2 cycles of high-dose cytarabine and in light of the FLT3-ITD mutation, sorafenib was added. Because his leukemia was considered “poor-risk” given the extramedullary disease at presentation, complex karyotype, and FLT3-ITD mutation, he underwent a 7/10 haploidentical allogeneic hematopoietic cell transplant (alloHCT) from his father in first remission. Conditioning included fludarabine, cyclophosphamide, and low-dose total body irradiation as per the standard Hopkins regimen []. Prior to alloHCT, multiparameter flow cytometry from the University of Washington showed no evidence of measurable residual disease (MRD). Posttransplant immunosuppression consisted of cyclophosphamide, tacrolimus, and mycophenolate mofetil. A bone marrow biopsy and restaging PET CT at approximately day +60 confirmed an ongoing CR and 100% donor chimerism in the CD3, CD14/15, and CD19 compartments. For posttransplant maintenance, he received 6 cycles azacitidine (given daily for 5 days at 32 mg/m2 in 28-day cycles)—initiated at approximately day +100—followed by maintenance sorafenib 200 mg twice daily. His tacrolimus was discontinued at approximately 6 months posttransplant with no evidence at any point of either acute or chronic graft-versus-host disease (GVHD).\nAt 13 months posttransplant, he developed progressive neutropenia. Bone marrow evaluation revealed relapsed leukemia with 42% blasts expressing a slightly different immunophenotype than that of his original disease (CD117-negative and CD5-positive). Immunohistochemical stains on the core biopsy demonstrated that blasts were positive for CD34, TdT, CD5, and CD7, with a small subset that was weakly positive for CD3. Cytogenetic studies demonstrated a complex karyotype similar to that of his original leukemia. FLT3-ITD PCR was negative but extended mutational testing—not previously performed—revealed mutations in FBXW7, NOTCH1, and EZH2, all of which are recurrently mutated in T-ALL []. Additionally, bone marrow chimerism studies showed for the first time a decline in CD3 donor chimerism from 100% to 91%.\nBased on emerging data to support the use of venetoclax in T-ALL, he began salvage therapy with venetoclax (given daily, initially at 800 mg then dose reduced to 400 mg due to the interaction with his azole for fungal prophylaxis) in combination with decitabine (given daily for 5 days at 20 mg/m2 in 28-day cycles). After 2 cycles, his peripheral blood counts had normalized, formal CR criteria were met, and a restaging bone marrow evaluation demonstrated no morphologic evidence of residual leukemia. MRD assessment—again performed via multiparameter flow cytometry at the University of Washington—also showed no evidence of persistent disease. CD3 chimerism in the bone marrow was restored to 100% donor.\nIn light of the lymphoid origin of his relapsed leukemia, next generation sequencing (NGS) was performed (ClonoSEQ, Adaptive Biosciences) on his relapse specimen, identifying a dominant T-cell receptor (TCR) clone comprising 8.249% of total nucleated cells. We retrospectively also assessed his original diagnostic bone marrow specimen and found that the same TCR clone was present in 11% of total nucleated cells. MRD assessment from a bone marrow specimen after 2 cycles of venetoclax and decitabine—also via ClonoSEQ—showed no detectable residual leukemia at a sensitivity of 1 leukemic cell per 106 cells. He received a total of 5 cycles of decitabine and venetoclax, with intermittent dose interruptions of venetoclax due to neutropenia. He remained MRD negative via multiparameter flow cytometry and ClonoSEQ and subsequently underwent a second haploidentical alloHCT with fludarabine, cyclophosphamide, and low-dose TBI conditioning. Decitabine and venetoclax were discontinued shortly prior to the second haploidentical alloHCT. He achieved full donor chimerism at day +18 posttransplant and continues in follow-up.

Anti-CD20 Treatment of Autoimmune Hemolytic Anemia Refractory to Corticosteroids and Azathioprine: A Pediatric Case Report and Mini Review
|
A previously healthy 3.5-year-old male was referred to our department because of a five-day history of weakness and pallor. Two weeks before, a three-day history of diarrhea was mentioned. The past medical history is unremarkable, and no family history of hematological problems or autoimmune disorders was reported.\nPhysical examination revealed jaundice, pallor, and splenomegaly. The boy's heart rate was 125 beats/min, and a 2/6 systolic heart murmur was present. The initial laboratory investigation showed: hemoglobin 5.1 g/dL, absolute reticulocyte count 220 × 103/μL, mean corpuscular volume 75 fl, white blood cells 9.3 × 109/L, and platelets 255 × 109/L. The peripheral blood film showed polychromasia and spherocytes without schistocytes. Serum lactate dehydrogenase levels were 1540 U/L, total bilirubin 3.8 mg/dl, and indirect bilirubin 0.9 mg/dl. The renal and liver function tests showed calcium and phosphate were normal. Urine examination was negative for hemoglobin and myoglobin. The direct antiglobulin test (DAT) was strongly positive for IgG autoantibodies with no fixation of the complement. The results of antinuclear antibody and anti-deoxyribonucleic acid were negative. Serum C3 and C4 as well as IgG, IgM, and IgA levels were normal. Serology for cytomegalovirus, Epstein–Barr virus, Mycoplasma pneumonia, and human immunodeficiency virus were negative. Based on the symptoms, the clinical findings and the laboratory tests the warm type of AIHA was established.\nErythrocyte transfusion was firstly administered because of the severe anemia in order to avoid cardiovascular compromise. Intravenous methylprednisolone was also initiated at a dose of 3 mg/kg/day for the first 72 hours with excellent hematological response. When the boy was clinically stable, oral prednisolone at a dose of 2 mg/kg/day was then used for 4 weeks followed by a slow taper during the following 5 months. At that time, prednisolone was discontinued, and a relapse occurred after an upper respiratory infection as shown in .\nFor this reason, prednisolone was restarted at 2 mg/kg/day with a good hematological response. Due to the steroids side effects, the dose of prednisolone was slightly reduced two weeks later and a hematological deterioration occurred. After that, the dose was increased again to 2 mg/kg for 1-month period. The expected side effects, such as blood pressure above the 95th percentile, bilateral posterior subcapsular cataract, facial edema, and hairy back, were quite evident, and it was decided to slowly discontinue prednisolone and to administer azathioprine at a dose of 2 mg/kg/day.\nAzathioprine was given for 4 months with a slight hematological deterioration despite the increase up to 3 mg/kg/day, as shown in , while the boy suffered from mumps, possibly due to the underlying immunosuppression. At this point, rituximab was initiated after informed written consent. The agent was given in 4 weekly doses at a dose of 375 mg/m2, with no infusion-related side effects. Stable response was noticed 2 months after initiation of rituximab (). Immunoglobulin levels remained normal without the need for replacement therapy with intravenous immunoglobulin (IVIG). The DAT became negative 12 months later. The boy remains disease-free without relapses, 3 years after the first presentation.

Tocilizumab for the Treatment of Mevalonate Kinase Deficiency
|
We present the case of a twelve-year-old girl originally from the Faroe Islands with compound heterozygotic MKD (p.V377I/c.417insC), who first presented with symptomatic periodic fever attacks from the age of 3 months. These presented as recurrent episodes of fever (39–41°C) without infectious cause, occurring once or twice monthly, associated with rigors, pallor, fatigue, lymphadenopathy (inguinal, axillary, and intra-abdominal), abdominal pain, oral ulceration, and arthralgia/myalgia of the lower limbs. Attacks lasted between 3 and 7 days and were accompanied by very high acute phase responses (C reactive protein [CRP] typically greater than 100 mg/L). Attacks were also triggered by vaccinations. Her past medical history included an episode of Stevens–Johnson syndrome in response to penicillin at the age of three years and appendectomy aged 7 years of a normal appendix. She was referred to us in London at the age of 12 years. At that time, she was receiving the anti-TNFα agent etanercept, which she had been on for the previous 34 months. She had at best only partial response to etanercept in terms of attack severity and duration, but was still missing 100 days per year of school because of attacks which occurred twice a month, lasting for 3 days. In addition, despite etanercept, her inflammatory markers remained significantly raised between attacks: CRP 82 mg/L (reference range [RR] < 10); serum amyloid A (SAA) 1310 mg/L (RR < 10), indicative of severe systemic inflammation in-between attacks and significant risk of reactive AA amyloidosis. Anakinra (2 mg/kg/day; recombinant interleukin-1 receptor antagonist) had also been tried previously, but was complicated both by a severe skin rash and also by the worst disease flare she had ever experienced; hence after four weeks, this was discontinued. Following a six-week washout period from the etanercept (during which she suffered one severe attack), in December 2015 she started intravenous tocilizumab 8 mg/kg every 2 weeks.\nAfter one dose of tocilizumab, her CRP and ESR both rapidly normalised (). She had one minor attack with minor, short-lived fleeting rash, but no fever after the first dose. Since normalisation of CRP is a well-known effect of tocilizumab and may occur without necessarily any true improvement in clinical disease activity, we also prospectively used a physician global assessment of disease activity using a 0 to 10 scale, 0 indicating no disease activity and 10 indicating severe disease activity (), and change in haemoglobin, white cell count, and platelets () as adjunctive laboratory indicators of successful treatment. In addition, the patient reported significant improvement even after a single dose of tocilizumab, with improved energy levels, reduction in pain, and improvement in oral ulceration. She was also able to return to full-time school.\nThis excellent clinical and serological response has been sustained for more than 24 months. There have been no reported adverse events. The patient was switched to weekly subcutaneous tocilizumab at 162 mg in June 2016 for ease of administration and reduction in hospital attendances. A year since that change, the patient has had several short-lived flares lasting 1–3 days associated with fever, adenitis, and mouth blistering, but she has not required prednisolone as before and overall expressed a preference for the subcutaneous route as it was associated with improved quality of life despite the breakthrough fever attacks.

Positive Seatbelt Sign with Avulsed Leiomyoma following Motor Vehicle Accident Leading to Hemoperitoneum
|
A 29-year-old G0P0 South Asian female was brought into the ED via ambulance following an MVA at freeway speeds involving multiple vehicles. The crash resulted in the deployment of the airbags and a subsequent loss of consciousness in the patient lasting less than one hour. Blood pressure was 89/40 on scene and improved to 117/95 en route to the ED. Upon arrival to the ED, the patient complained of 10/10 pain in the abdomen and left hip. Triage vitals were as follows: blood pressure 96/58, heart rate 85 beats/minute, respiratory rate 19 breaths/minute, and Glasgow coma scale 15/15. The patient arrived with a cervical collar and backboard in place and was noted to have a positive seat belt sign. A focused assessment with sonography for trauma (FAST) exam was positive in the right upper quadrant (). Leiomyomata uteri were incidentally noticed on ultrasound (Figures and ). A pelvic X-ray showed no acute fracture or traumatic malalignment. Hemoglobin was 10.7 grams/deciliter (reference range 12-16 grams/deciliter). The patient was subsequently taken to the operating room where a midline laparotomy was performed with an immediate upwelling of blood. The abdomen was packed in all four quadrants to control bleeding and stabilize blood pressure. Upon unpacking and inspection of the upper quadrants, no damage was observed to the mesentery, colon, liver, or spleen. Inspection of the lower quadrants revealed a free-floating mass of tissue later identified as a leiomyoma (). In addition, the uterus was noted to be bleeding from a 5 cm fundal laceration. The uterus appeared fibroid in character, and a 3 cm subserosal leiomyoma was seen extending into the laceration. The gynecologic team was consulted and proceeded to inject 20 units of vasopressin in 60 cc dilution into the uterus. This was followed by a myomectomy of the subserosal leiomyoma and closure of the uterine laceration. The abdominal incision was then closed, with a total estimated blood loss of 1000 mL. The patient was administered 2 units each of red blood cells and fresh frozen plasma, as well as 1.3L of crystalloid intraoperatively. Hemoglobin on post op day 1 downtrended to 6.5, at which point a third unit of red blood cells was given. On post op day 2, the patient developed intractable nausea, after which a nasogastric tube was inserted and 1 liter of green bilious output was achieved. The patient was stabilized and transferred to an outside hospital on post op day 3 for further recovery.

An unusual presentation of a papillary thyroid carcinoma in the struma ovarii in a 10 year-old girl: A case report
|
A 10 year-old girl presented with the complaint of palpitation to a cardiologist. She had normal physical examination and laboratory tests, except tachycardia (heart rate = 130 per minute) and low TSH levels (0.005) with normal T3 (9.46) and T4 (145). She was referred to endocrinologist for possible hyperthyroidism evaluation. The thyroid gland was normal size, with no nodularity. She was diagnosed with possible thyrotoxicosis, but due to the normal physical examination, she underwent thyroid scan to rule out possible thyroiditis, which did not show any uptake in the thyroid gland, while there was an increased uptake in the right ovary (). Pelvic trans-abdominal sonography showed a heterogeneous complex solid mass of 113 × 112 × 100 mm with volume of 670 cc in the right ovary with no ascites. The patient had no complaint of abdominal pain or pelvic pain or abnormal uterine bleeding.\nShe was treated with methimazole 10 mg daily and propranolol 40 mg daily and were candidate for surgery after being euthyroid. The patient was referred to a gynecologist with the possible diagnosis of struma ovarii for further evaluation. She underwent right oophorectomy with the presumption of teratoma combined with thyroid-stimulating hormone (TSH)-suppressive therapy following treatment with I131. Total thyroidectomy was performed to permit evaluation for metastatic disease and monitoring for recurrence by thyroglobulin levels. The pathology report of the ovary mass indicated teratocarcinoma with 60% well-differentiated follicular thyroid carcinoma and 40% well differentiated follicular-variant with tumor necrosis, microscopic capsular invasion and peritumoral lymphovascular invasion, considering stage IC of PTC () and the thyroid gland did not show pathologic features of PTC.\nFurther evaluation with whole body scan with Iodine 123 (I123) showed metastasis to lymph nodes. She had high levels of thyroglobulin and received iodine therapy (150 mCi) twice. In the follow-up whole body scan, there was no trace of iodine uptake and the patient was symptom free.\nThe patient is now under treatment with levothyroxine 0.1 mg daily. Following 8 months after surgery and iodine therapy, she is totally symptom free.

A foreign body in inguinal canal: A case report
|
A 74-year-old obese male was presented to ED (Emergency Department) with abdominal pain, distension, vomiting and diarrhea for 5 days. His past medical history is significant for hypertension and CVA (Cerebrovascular accident) 3 years before admission. He had a Colonic polyp removed 5 years ago. In addition, He had a history of gallstones removed 10 years ago. He was on Atenolol. Captopril and, Aspirin. On examination, the patient had generalized weakness of the left side of his body due to previous CVA.\nThere was a tender irreducible swelling in the right inguinal region, covered by normal skin. Since the patient had a history of stroke years ago, it was not possible to ask him about duration of the swelling, pain at the site, or to cough to evaluate the swelling more. The vital signs were within normal. Bowel sounds were sluggish. Digital rectal examination showed nothing of significance.\nLab results showed Blood Urea: 11.8 mmol/L, Serum Creatinine: 116.96 μmol/L, Serum Potassium: 5.5 mmol/L, Blood Sugar: 10.3 mmol/L, WBC Count: 14.2 × 103/mm3, Hemoglobin: 12.4 g/dL, Platelets: 312 × 103/mm3.\nOn Abdominal ultrasound, the gallbladder wasn’t visualized, but a cystic like lesion in the right inguinal region mostly representing a bowel loop was seen. The tentative diagnosis for this case was strangulated right inguinal hernia causing intestinal obstruction. Consent was taken from the patient’s next of kin and the right inguinal region was explored. A sliding direct Ogilvie inguinal hernia was discovered. There was a well circumscribed soft mass of a narrow neck, protruding from the posterior wall of the hernia that looks like a foreign body (). On exploration, the mass was the balloon of a Foley's catheter in the sliding part of the bladder within the inguinal hernia, and the urinary bladder was part of the posterior wall of the inguinal canal (). The direct sliding Ogilvie inguinal hernia was repaired, and Explorative laparotomy was done to deal with the cause of intestinal obstruction through a mid-line incision. Upon exploration, a superior mesenteric artery occlusion was noticed causing strangulation of all small bowel (excluding first 100 cm of jejunum), all right colon and most of transverse colon. Resection of all gangrenous bowel was done, with end to end jejuno-colonic anastomosis. The patient’s case deteriorated over the next few days until he died on the 5th day post operation due to cardiac issue.

Bevacizumab: A Rare Cause of Nonischemic Cardiomyopathy
|
A 68-year-old woman with past medical history of hypertension, chronic kidney disease stage 3, hyperlipidemia, and hereditary hemorrhagic telangiectasia (HHT) presented to the emergency department with sudden onset of shortness of breath. She also reported chest pain, orthopnea, and paroxysmal nocturnal dyspnea. Review of systems was otherwise unremarkable. Her HHT was previously managed by regular blood transfusions and epsilon-aminocaproic acid. Because of the need for frequent blood transfusion due to persistent epistaxis and gastrointestinal bleeding, she was started on bevacizumab infusion at 15 mg/kg/dose (1150 mg total) by her haematologist a month prior to presentation. Initial vital signs on presentation revealed respiratory rate of 25/min, oxygen saturation of 65% on ambient air, blood pressure of 138/83 mmHg, and pulse rate of 92/min. Physical examination revealed respiratory distress with diffuse wheeze, jugular venous distention, and trace pedal edema. Laboratory tests revealed markedly elevated brain natriuretic peptide (BNP) of 1697 pg/ml (normal 0–100 pg/ml) with initial troponin of 0.05 ng/ml (normal < 0.04 ng/ml). Chest X-ray revealed pulmonary vascular congestion and interstitial edema with mild cardiomegaly. She was immediately placed on noninvasive ventilation and started on intravenous furosemide with quick symptomatic improvement. Transthoracic echocardiogram (TTE) showed ejection fraction of 30% and global hypokinesia (please see Supplementary Materials ()). Of note, TTE done three years prior to index presentation showed ejection fraction of 56%. She does not drink alcohol, and her thyroid function and sedimentation rate were normal making other etiologies of acute systolic heart failure such as thyroid disorder, alcoholic, or inflammatory cardiomyopathy less likely.\nShe refused to wear LifeVest and was placed on guideline-directed medical therapy including beta-blocker, angiotensin-converting enzyme inhibitor (ACEi), and aldosterone antagonist along with an oral diuretic. The patient progressively improved and was discharged three days later and scheduled for follow-up with cardiology for outpatient right and left heart catheterization. Two weeks later, she developed another episode of flash pulmonary edema deemed to be due to medication noncompliance. On this occasion, she underwent left and right heart catheterization which revealed widely patent coronary vessels (), elevated pulmonary capillary wedge pressure, and elevated left ventricular end-diastolic pressure. She continued to have her monthly bevacizumab infusions with her haematologist as this was not thought to be the cause of her cardiomyopathy at the time. Three months later, she developed sudden onset of chest pain and shortness of breath at home and went into ventricular fibrillation-related cardiac arrest. She underwent prolonged cardiopulmonary resuscitation but eventually had return of spontaneous circulation. She was intubated and admitted to the medical intensive care unit and underwent therapeutic hypothermia. Repeat TTE showed ejection fraction of 34%. She quietly passed away 3 days later.

Meningococcal Pneumonia in a Young Healthy Male
|
A 23-year-old male presented to the emergency department with one-day history of right-sided pleuritic chest pain, haemoptysis, and fever. He had no history of a recent travel or contact with sick individuals. The patient had no significant medical background, and he was not taking any regular medication.\nOn admission, blood pressure was 140/60 mmHg, heart rate 89/min, body temperature 40°C, respiratory rates 20 breaths/min, and oxygen saturation 98% in room air. Physical examination revealed rales and bronchial breathing in the right infrascapular region. There was no clinical evidence of meningitis.\nLaboratory analysis showed the following results: haemoglobin level 146 g/L (normal 140–175), platelets count 373 × 109/L (normal),white blood cell counts 19.6 × 109/L (normal 3.5–10.0) (90% neutrophils and 10% lymphocytes), sodium 140 mmol/L (normal 135–145), potassium 3.6 mmol/L (normal 3.5–4.5), urea 3.7 mmol/L (normal 2.5–7.0), creatinine 104 µmol/L (normal 50–100), eGFR 87 ml/min/1.7 m2 (normal > 90), C-reactive protein at 58.5 mg/L (normal < 3), and an unremarkable liver function test. Chest X-ray demonstrated right lower lobe consolidation. With the history of haemoptysis and pleuritic chest pain, computed tomography pulmonary angiogram (CTPA) was performed, and it did not show pulmonary embolism (PE).\nSputum culture was found to be positive for oropharyngeal Candida species. However, a day later, N. meningitidis grew in one blood culture bottle, and it was sensitive to penicillin and ceftriaxone. Using polymerase chain reaction (PCR), we have identified N. meningitidis serogroup Y. Subsequently, two repeat sets of blood cultures, after initiation of antibiotics, were sent and reported negative. Additional results included undetectable urinary Streptococcus and Legionella pneumophila serogroup 1 antigens and a negative HIV serology test.\nThe patient was started on 2 g of IV ceftriaxone and 100 mg of doxycycline as per the hospital guidelines for the management of community-acquired pneumonia. However, doxycycline was discontinued after day 1 after the blood culture result. In total, the patient received 4 days of IV ceftriaxone followed by 3 days of oral amoxicillin (1 gm,TDS). The Centers for Disease Control and Prevention was contacted to arrange chemoprophylaxis for the patient's contacts.\nOn day 4, the patient was discharged from the hospital and was reviewed at an outpatient clinic two weeks later. He showed a complete resolution of his symptoms.

An uncommon cause of hemoptysis: aortobronchial fistula
|
A 46-year-old man with a recent diagnosis of hiatal hernia was admitted to the Respiratory Diseases Unit of the University Hospital of Modena, Italy for several dramatic episodes of hemoptysis during the previous 30 days, severe anemia (6,9 g/dl) and initial signs of hemodynamic instability (shock index = 1,4). The past medical history revealed that the patient had undergone cardiac surgery for aortic coarctation at the age of 18 without complications neither during the immediate post-operative course nor in the following 20 years follow up period. He was referred to the Respiratory Intensive Care Unit of our Department where blood transfusion was immediately started. A chest X-ray was performed but no significant abnormalities were detected. Thus he underwent urgent digestive endoscopy that revealed a grade B esophagitis according to Los Angeles classification [] without any evidence of recent bleeding. Fiber bronchoscopy was then immediately conducted showing limited traces of blood in the bronchial tract afferent to the left upper lobe while no sings of active bleeding was found (Fig. ). He eventually underwent a contrast-enhanced CT scan of the chest that showed an aneurysmal dilatation of the descending thoracic aorta (Fig. ) communicating with the left upper bronchus, whose upper posterior hemorrhagic leak determined initial left upper lobe compression and ground-glass opacities with scissural delimitation (Fig. ). Given the evidence of a communication between aortic aneurism and lung parenchyma or either the tracheobronchial tree the patient was referred to the Cardiac Intensive Care Unit. Thoracic endovascular aortic repair (TEVAR) was preferred rather than a more invasive open surgical approach due to the persistent hemodynamic instability of the patient. Aortobronchial fistula was thus successfully treated with endovascular stent-graft without complications. The patient survived the intervention with uneventful postoperative course and good recovery in less than 30 days. Strict follow up was then started.

Persistent megalocystic ovaries after ovarian hyperstimulation syndrome in a postpartum patient with polycystic ovarian syndrome: a case report
|
A 34-year-old woman (gravida 4, para 1, abort 3) presented to our clinic for pelvic pain and enlarged ovaries at PUMCH (Peking Union Medical College Hospital) with a 5-day history of left lower quadrant abdominal pain. The pain was atypical, without nausea, vomiting, dysuria, or diarrhea. Her last menstrual period was 2 weeks prior to presentation. There were palpable, cystic, solid masses on both sides in the lower quadrant. Laboratory tests revealed a white blood cell count of 22.9 × 109/L, granulocyte rate of 80.6%, and a normal β-human chorionic gonadotropin (β-hCG) level. She had a transient fever of 37.9 °C; therefore, antibiotics was administered for 4 days. When she came to our hospital, pelvic pain was relieved. Ultrasound imaging and computed tomography (Fig. ) revealed that both the ovaries were enlarged (≥10 cm) with multiple follicles inside. Serum hormone levels were normal: follicle-stimulating hormone (FSH), 2.38 IU/L; E2, 46.85 pg/mL; progesterone (P), 0.35 ng/mL; testosterone (T), 0.54 ng/mL; luteinizing hormone (LH), < 0.2 IU/L; prolactin (PRL), 7.44 ng/mL.Dehydroepiandrosterone (DHEA), 497.5 μg/dL and 24-h urinary-free cortisol (UFC), 165.24 μg were slightly higher than normal. Adrenal ultrasound, serum thyroid-stimulating hormone (TSH)/free thyroxine (FT4), thyroxine (T4) and hypothalamic-pituitary magnetic resonance imaging revealed no abnormality. The concentration of tumor marker CA125 was 365.7 U/mL; therefore, a malignant tumor could not be excluded.\nBefore presentation, she was diagnosed with PCOS and underwent several attempts of ovulation induction and intrauterine insemination. After these failed, she underwent IVF with Marvelon (N.V. Organon, Oss, The Netherlands) and GnRHa stimulation. A combined estrogen and progesterone pill (Marvelon; N.V. Organon) was administered from day 5 of the previous cycle, and 1.2 mg triptorelin embonate (Diphereline; Ipsen Pharma Biotech, France) was injected intramuscularly on day 16 of taking Marvelon. Stimulation with recombinant follicle-stimulating hormone (Puregon; N.V.Organon) was started subcutaneously after 16 days’ down-regulation. Human chorionic gonadotropin (HCG) 5,000 IU was injected when the maxium follicle diameter reached 20 mm. The IVF procedure was performed at another center; therefore, details of estrogen and follicle development could not be traced. Transvaginal oocyte retrieval was uneventful and yielded 24 mature oocytes. Two blastocysts were transferred 4 days later. The patient had severe OHSS 10 days after oocyte retrieval, for which paracentesis was performed three times, with an average of 1,500 mL abdominal effusion drained each time. She was also suspected to have vein thrombosis of the right lower limbs. The patient became pregnant, and the follow-up was performed at another center. Throughout her perinatal examinations, both the ovaries did not become smaller. The patient delivered a healthy newborn via cesarean at term, a biopsy of the enlarged ovary was performed with benign pathology. No intervention was performed due to the expectation that the hyperstimulated ovaries would shrink during the postpartum period, at the same time she was concerned about the side-effects of those medicines in lactation. Her menstrual period resumed 14 months after delivery, and the child was weaned from breastfeeding at 24 months. However, the size of both the ovaries were still not reduced by then. Three months of oral contraceptives (Marvelon; N.V. Organon) were prescribed.\nAfter admission, she underwent laparoscopic surgery to determine the cause of the persistent enlarged ovaries as well as pain. During laparoscopy, we found a large, torsed, congestive left ovary and a torsed, congestive, ipsilateral fallopian tube. The contralateral adnexa were enlarged but had a normal color. Both ovaries measured approximately 10 × 12 cm, kiss-forming, were closely stuck together. There were minimal ascites in the abdominal cavity. The omentum majus was adhered to and laid over the left ovary. Laparoscopic detorsion followed by left ovary biopsy and bilateral ovarian acupuncture were performed (Fig. ). Histopathological examination (Fig. ) revealed localized congestion and necrosis of the ovary that underwent biopsy, with no associated lesions. Ovary puncture liquid showed elevated E2 (2,078 pg/mL) and decreased FSH (0.3 IU/L) and LH (< 0.2 IU/L). The postoperative course was uneventful.\nThe patient was discharged the following week and received GnRHa 3.75 mg for 3 months. The ovaries shrank somewhat during the first month (left ovary, 5.8 × 5.1 cm; right ovary, 9.3 × 6.3 cm). Four months after surgery, she underwent an ultrasound scan that found slightly enlarged ovaries with multiple follicles (left ovary, 6.5 × 4.7 cm; right ovary, 4.1 × 3.0 cm). She did not feel any discomfort; therefore, she was advised to return 6 months later with no further treatment.

Leukemic arthritis and severe hypercalcemia in a man with chronic myeloid leukemia: a case report and review of the literature
|
A 35-year-old Thai man was diagnosed as having CML in the chronic phase in February 2016 during his annual checkup at a primary hospital; the diagnosis was confirmed with a cytogenetic study, which demonstrated 46,XY,t(9;22) [] and was positive for the BCR-ABL fusion gene. He was therefore referred to our hospital in July 2016 to receive definitive treatment of 400 mg/day of imatinib. After receiving imatinib, his treatment response was monitored by a real-time quantitative polymerase chain reaction (RQ-PCR) for the BCR-ABL gene using the international scale (IS) method. The results showed an optimal response was achieved at 3 and 6 months, according to the 2013 European LeukemiaNet recommendations, with RQ-PCRs for the BCR-ABL gene (IS unit) of 1.527% and 0.896%, respectively []. During the treatment, he showed good compliance, and he did not use any herbs or other medications. He denied a family history with hematologic malignancies and he had no psychological problems.\nIn February 2017, however, he was admitted to our hospital with fever and severe pain in both knees and ankles of 5 days’ duration. A physical examination showed symmetrical oligoarthritis in his knees and ankles. A complete blood count (CBC) revealed hemoglobin (Hb) of 6.5 g/dL, hematocrit (Hct) of 20.3%, a WBC count of 16.9 × 109/L (49% neutrophils, 42% lymphocytes, 1% monocytes, 1% basophils, and 7% myeloblasts), and a platelet count of 16 × 109/L. A synovial fluid analysis of his right knee showed a clear, colorless fluid with an absence of crystals and a WBC count of 180 cells/L, with 65% neutrophils, 32% lymphocytes, and 3% blasts. A synovial fluid culture and hemoculture yielded no growth. A bone scintigraphy revealed: a symmetrical blood flow to both ankles; a symmetrical soft-tissue uptake at the knees and ankles, with a prominent early bone uptake; and a symmetrical increased uptake at the mandible, bilateral proximal humeri, both elbows, both forearms, the bilateral femoral heads, the trochanteric region of both femora, the left femoral shaft, the distal femora, the proximal tibiae, the bilateral tibial shafts, and both distal tibiae, all of which favored a bone marrow expansion which might have been related to a leukemic infiltration (Fig. ). The real-time quantitative-polymerase chain reaction (RQ-PCR) for BCR-ABL/ABL (IS unit) had increased to 21.26%. Testing for mutations in the BCR-ABL gene showed a negative result. A bone marrow aspiration revealed 10% myeloblasts. CML blast phase was established due to the highly suspicious evidence of extramedullary blasts at multiple bones and joints. Induction therapy with a 7 + 3 induction regimen (200 mg of cytarabine administered intravenously on days 1–7, plus 15 mg of idarubicin administered intravenously on days 1–3) was prescribed in conjunction with 600 mg of imatinib once daily before switching to 140 mg of dasatinib. His clinical symptoms, including joint pain and fever, improved, and he achieved a complete hematological remission, confirmed by a bone marrow study, 4 weeks after the induction therapy. Unfortunately, he developed dyspnea on exertion after dasatinib treatment for a month, and pleural effusion with pulmonary hypertension were suspected from the dasatinib. We therefore decided to permanently stop administering the medication.\nA month later, in November 2017, he presented to our hospital with severe headaches of 1 week’s duration, a low-grade fever, nausea, vomiting, and polyuria. A physical examination revealed hepatosplenomegaly without an abnormal neurological finding. A CBC revealed Hb of 12.8 g/dL, Hct of 39.1%, a WBC count of 20.8 × 109/L (87.1% neutrophils, 9.1% lymphocytes, 2.6% monocytes, 0.7% eosinophils, 0.5% basophils, and no blasts), and a platelet count of 282 × 109/L. A computed tomography (CT) scan of his brain (non-contrast) showed several osteolytic lesions with soft tissue formation at the skull, skull base, and mandible, without intracranial lesions (Fig. ). A film bone survey demonstrated moth-eaten osteolytic bony destruction scattered diffusely on the pelvic bone, skull, spine, and both femurs (Fig. ). His laboratory chemistry revealed serum blood urea nitrogen (BUN) of 64.8 mg/dL, creatinine (Cr) of 4.1 mg/dL, albumin of 4 g/dL, globulin of 4.3 g/dL, total calcium of 17.8 mg/dL, serum parathyroid hormone (PTH) of 9.82 pg/mL (normal 15–65 pg/mL), 25-hydroxyvitamin D of 50.64 ng/mL (normal ≥ 30 ng/mL), and uric acid of 17.4 mg/dL; all other laboratory results were normal. The serum 1,25-dihydroxyvitamin D and PTH-related protein (PTHrP) levels were not available as the relevant tests were not routinely provided by our hospital at that time. A bone marrow aspiration showed multiple stages of the myeloid series with 7% myeloblasts. He was treated with intravenously administered hydration (200 mL/hour of 0.9% normal saline), calcitonin (300 μg administered intravenously every 6 hours for 3 days), and imatinib (600 mg/day). However, as there was a minimal response in his high serum calcium level, we decided to add 20 mg/day of intravenously administered dexamethasone on day 8 of admission. His severe headache symptom improved gradually, and the serum calcium level decreased dramatically to the normal range within a few days. He was then discharged with a serum calcium level of 7.6 mg/dL on day 15 of admission. His hypercalcemic treatment and outcomes are illustrated at Fig. . After that, he was lost to follow-up and died a few weeks after discharge at his home with unknown cause of death. A timeline table of our patient is provided in Additional file .

An Unusual Cause of Acute Heart Failure: A Case Report of Iliocaval Venous Stent Migration
|
A 61-year-old female with medical history of hypertension, diabetes mellitus type 2, and chronic kidney disease stage V was transferred to our institution from an outside hospital for further evaluation and definitive management of a migrated intracardiac stent.\nShe initially presented to the outside facility with progressive dyspnea on exertion, orthopnea, and bilateral lower extremity edema. She was initially diagnosed with acute heart failure and pneumonia and treated with diuretics and antibiotics. Subsequently, a transthoracic echocardiogram was performed, which revealed a foreign body within the right ventricle. On transfer to our facility, a transesophageal echocardiogram revealed a long stent straddling the tricuspid valve from the right atrium with the other end lodged in the trabeculation of the right ventricle with severe tricuspid regurgitation ().\nOn further investigation, we learned that the patient had undergone peripheral endovascular intervention for May-Thurner syndrome with placement of a self-expanding Nitinol Protege (14 mm × 60 mm) stent to the left iliac vein 6 months prior to presentation.\nA percutaneous endovascular approach with a 35- mm Medtronic-Covidien Amplatzer Gooseneck Snare was initially attempted to retrieve the migrated stent. However, the snared proximal segment fractured, leaving behind 2 stent fragments. After ensuring there was no myocardial perforation or pericardial effusion with intracardiac ultrasound, the patient was referred for surgical extraction via median sternotomy with use of cardiopulmonary bypass.\nDuring the operative procedure, the stent was found to be densely adherent to the tricuspid leaflets and the subvalvular apparatus, with majority of the primary chords to the anterior and posterior leaflets ruptured (). After successful extraction of the stent and native tricuspid valve, she underwent valve replacement with a 29-mm Carpentier-Edwards bioprosthetic valve. Her postoperative course was complicated by hemopericardium secondary to anticoagulation resulting in cardiac tamponade that was drained percutaneously, and small thromboembolic cerebellar stroke from atrial fibrillation. She was discharged to an inpatient rehabilitation facility and did well on 8-month follow-up.

Utility and effectiveness of Symbicort® Turbuhaler® (oral inhalation containing budesonide and formoterol) in a patient with severe asthma after permanent tracheostomy
|
Patient: A 76-year-old woman.\nChief complaint: To improve asthma management before undergoing neck surgery.\nPast medical history: Diabetes, hypertension, pollen allergy.\nTobacco use: No.\nCurrent medication (antiasthmatic drugs): Symbicort® Turbuhaler® (Symbicort), 2 inhalations twice daily up to a total of 8 inhalations per day (SMART); montelukast tablets 10 mg/day; theophylline sustained-release tablets 400 mg/day; ketotifen capsules 2 mg/day; salbutamol inhalation 0.5%, 0.5 mL/asthma attack; and prednisolone tablets 5 mg, to be taken at the patient’s discretion at the time of an attack.\nRespiratory function test: Forced vital capacity, 2.74 L (129.2%); forced expiratory volume for 1 s (FEV1), 1.09 L (76.8%); FEV1, 39.8%, with findings of obstructive ventilatory defect.\nCurrent medical history: Adult-onset asthma. Despite undergoing Step 4–5 (Global Initiative for Asthma 2017 [GINA2017]) therapy as a long-term management approach, wheezing persisted, and she had been admitted to a nearby hospital once every 2 years or so due to asthma attacks triggered by irregular weather conditions.\nShe was referred by a nearby otolaryngologic clinic to the Department of Otorhinolaryngology in our hospital for thorough examination of hoarseness lasting for 1–2 years. Examination findings revealed thyroid cancer with tracheal infiltration for which radical surgery was indicated. However, because wheezing increases surgical risk, she was referred to the Department of Internal Medicine for preoperative control of intractable wheezing. Consistent with her complaint of constant wheezing, initial examination revealed expiratory wheezing at rest.\nTo improve asthma management during a 4-week period before surgery, we prescribed Spiriva® Respimat® (Spiriva Respimat) 2.5 μg (two inhalations once daily) and subcutaneous injections of 300 mg anti-IgE antibody omalizumab every 2 weeks (determined based on the level of serum IgE [159 IU/mL IgE specific to Aspergillus fumigatus] and body weight [50.9 kg]).\nOwing to these additions, wheezing disappeared after 1 week, and so the patient was able to undergo right thyroid lobectomy with tracheoesophageal resection as scheduled.\nConsidering that it would be difficult for the patient to use the inhalation powder Symbicort because of a permanent tracheostomy postoperatively, we switched from Symbicort to nebulized budesonide 2000 μg/day and a tulobuterol patch (2 mg). Spiriva Respimat and omalizumab were continued after surgery.\nApproximately 3 weeks after surgery, the patient began to develop respiratory distress and wheezing early in the morning. According to the patient, these attacks would have been managed quickly as small attacks by additional inhalations of Symbicort, suggesting that the nebulized SABA that she had been taking postoperatively was not sufficiently effective. Because these symptoms used to be well managed when Symbicort was used, we considered switching back to Symbicort from nebulized budesonide and the tulobuterol patch. In Japan, however, Symbicort is available in only a DPI formulation, Turbuhaler®. In order to maximize the beneficial effects of Symbicort Turbuhaler, inspiratory flow rates need to exceed a certain level, but our patient would likely have had insufficient inspiratory flow rate due to the tracheostomy, and would thus need a device that does not require a high inspiratory flow rate, such as a pressurized metered-dose inhaler (pMDI). Adoair® and Flutiform® aerosols are commercially available pMDIs in Japan and contain ICS/LABA. Flutiform® aerosol was considered the most likely candidate because it contains the same LABA (formoterol), but not ICS, as in Symbicort, but Flutiform may leak out from the tracheostomy after being sprayed intraorally. Because the patient had previously been undergoing SMART with additional inhalations of Symbicort for acute exacerbations, it would be best to use Symbicort if possible. There seems to be no difference in the degree of distribution to the respiratory tract whether a tracheostomy is present or not if the patient is able to close the tracheostomy using his or her hand. However, the drug distribution in the respiratory tract is unknown when a patient with a tracheostomy uses an inhaled drug. Since the diameter of the tracheostomy is about 1 to 2 cm, the dead space can potentially be ignored. When the effect was found to be inadequate, we considered a change to Flutiform®, which has similar components in a different device (pMDI), because the tracheostomy was just under the skin in this patient.\nTwo types of devices are used to measure inspiratory flow rate: the whistle-type Turbutester (accessory for the Turbuhaler®) and the In-Check Dial®, an inspiratory flow measurement device. The Turbutester generates an audible whistling sound during inhalation, signifying that the patient has an adequate inspiratory flow rate to use Symbicort. The In-Check Dial, when used with an adapter tailored to conventional inhalers, functions as an inspiratory flow measurement device and expresses inspiratory flow rates in L/min. Our patient had an inspiratory flow rate barely sufficient to generate a whistling sound from the Turbutester during inhalation while simultaneously closing the tracheostomy with her hands. So, to select the best inspiratory flow rate, she was instructed to measure the rate three times using the In-Check Dial®, the Turbuhaler®, and the special adaptor while closing tracheostomy. The results were 40, 43, and 43 L/min. Several inspiratory flow rates have been suggested to be required to exert the beneficial effect of Turbuhaler®, but the consensus is that inspiratory flow rates above 30 L/min are sufficient to use Turbuhaler® [, ]. These findings, together with the findings from the Turbutester, suggest that the present patient could benefit from these devices.\nBased on these findings, nebulized budesonide 2000 μg and tulobuterol patch 2 mg were switched to 2 inhalations of Symbicort twice daily up to a total of 8 inhalations/day (SMART). The antiasthmatic drugs Spiriva Respimat and anti-IgE antibody, which had been added before surgery, were continued. The patient’s symptoms improved quickly over the course of 2 days after starting 2 inhalations of Symbicort in the morning and evening plus additional inhalations as needed (usually 1 inhalation in the evening). Owing to stabilized asthma symptoms, she was discharged on the third day after switching drugs (Fig. ).

A Switch of an Idea: Simultaneous High Tibial Osteotomy and Lateral Meniscal Allograft Transplantation
|
A 49-year-old female patient presented with complaints of worsening right knee pain since two years ago. The patient had pain when she walks, goes up the stairs, sits and gets up. The symptoms sustained even after three months of non-operative treatment. On physical examination, she had a full range of motion and had pain and tenderness on both lateral and medial joint line with positive McMurray test. No pain was observed during patellar grind and compression test. Mild to moderate degree of swelling and effusion were observed without significant instability. Plain radiographic examination showed Kellgren-Lawrence grade 2 medial compartment tibiofemoral osteoarthritis. Mechanical hip-knee-ankle axes were varus 6.5° in right knee and neutral in left knee. Posterior tibial slope angle was 4.2° and the Insall-Salvati ratio was 1.13 in right knee. Right knee magnetic resonance imaging (MRI) revealed a horizontal tear of the medial meniscus with grade 3 chondromalacia of medial femoral condyle and grade 2 chondromalacia of medial tibial condyle. Also, complex tear with extrusion of the lateral meniscus was observed with intact lateral femoral and tibial condyles. The patellofemoral joint had grade 2 chondromalacia (Figure ).\nThe International Knee Documentation Committee (IKDC) score and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score of the patient were 52 and 48, respectively. To address both medial compartment arthrosis and lateral meniscus tear, we planned to perform simultaneous medial open wedge HTO and lateral MAT after consulting with the patient. Knee arthroscopy was performed first, and the torn lateral meniscus was removed to within 1-2 mm of the peripheral rim, and a bleeding bed was made using a shaver. Biplanar medial open wedge HTO was performed under fluoroscopic control. Fixation of osteotomy was performed using an anatomical locking plate. After plate fixation, 5 cc of beta-tricalcium phosphate (Ca3(PO4)2) was injected into the osteotomy gap. To secure enough space for bony bridge fixation for lateral meniscal allograft in proximal tibia area, the osteotomy site and proximal screw position were made about 1.5 cm below the routine position (Figure ).\nThe lateral meniscus allograft was transplanted using the keyhole technique. A keyhole slot parallel to the posterior tibial slope was made just under the lateral tibial spine. After the graft was introduced into the joint through the anterior mini-arthrotomy site, inside-out meniscal suture fixations were performed at 5 mm intervals. Bony union of osteotomy site was achieved without any complication. Radiographic measurements at postoperative one-year follow-up showed valgus 2.7° of mechanical hip-knee-ankle axis, 4.9° of posterior tibial slope, and 1.07 of Insall-Salvati Ratio. Intact lateral meniscus allograft and lateral tibiofemoral cartilage were confirmed by the follow-up knee MRI taken at postoperative three months and second-look arthroscopic examination performed at postoperative 12 months (Figure ). Clinically, the patient had full knee range of motion and the improved IKDC and WOMAC scores of 95 and 12, respectively.

The Potential Use of 11C-Choline Positron Emission Tomography/Computed Tomography to Monitor the Treatment Effects of Radium-223 in a Patient with Prostate Cancer
|
A 59-year-old man had undergone prostate needle biopsy after a high prostate specific antigen (PSA) level (218.5 ng/mL) observed at the age of 54 years and he was diagnosed with adenocarcinoma of the prostate (Gleason score 4＋5). He underwent pelvic magnetic resonance imaging (MRI) and bone scintigraphy at our hospital. The MRI showed the mass in the right peripheral zone as a low signal intensity on the T2-weighted image and as an abnormal signal intensity on the diffusion-weighted image, reflecting prostate cancer. Bone metastases of the right rib and L2 vertebra were clarified. Therefore, clinical stage was T2aN0M1. He was treated with radiation therapy and androgen deprivation therapy (ADT) including bicalutamide and goserelin and his PSA dropped to 0.053 ng/mL. At the age of 56 years, his PSA was found to be elevated (1.15) and ADT with flutamide, estramustine phosphate, enzalutamide, and abiraterone was restarted. At the age of 58 years, the disease became refractory to hormonal treatment (PSA recurrence: 24.9 ng/mL), and the patient started chemotherapy with docetaxel for six cycles. However, both symptomatic and biochemical progression (PSA: 33.7 ng/mL) appeared. We confirmed multiple bone metastases without lymph node metastases or visceral metastases by carrying out baseline 11C-choline PET/CT and started Ra-223. He completed all the six cycles without any interruption and with no adverse events. Before each treatment, laboratory evaluation was performed to assess hematological parameters as well as PSA. After treatment cycles 3 and 6, 11C-choline PET/CT imaging studies were performed to evaluate and predict treatment response of Ra-223 on imaging.\nBaseline 11C-choline PET/CT showed multiple areas of increased focal activity in multiple cervical, thoracic and lumbar vertebrae as well as in both ribs, right ileum, and left ischium (Figures -). Second 11C-choline PET/CT after three cycles showed the increasing tumor activity in the existing lesions and the new uptake spots of thoracic spine, both ribs, and left ileum (Figures -). Third 11C-choline PET/CT after six cycles showed the increasing tumor activity in the existing lesions and the new uptake spots of thoracic spine, sacrum, right rib, and right ileum (Figures -).\nThe patient’s serum alkaline phosphatase (ALP) level was 226 U/L at baseline, 191 U/L after one cycle, 208 U/L after two cycles, 235 U/L after three cycles, 206 U/L after four cycles, 200 U /L after five cycles, and 262 U/L after six cycles, respectively. His serum PSA level was 33.7 ng/mL at baseline, 54.1 ng/mL after one cycle, 79.4 ng/mL after two cycles, 85.6 ng/mL after three cycles, 120 ng/mL after four cycles, 175 ng/mL after five cycles, and 267 ng/mL after six cycles, respectively. During Ra-223 therapy, his serum ALP did not dramatically change with minor increase and decrease and PSA gradually increased. After the completion of Ra-223 therapy, he started a new chemotherapy with cabazitaxel.

A Case of Isolated Gastrointestinal Histoplasmosis
|
A 60-year-old female presented with three days of diarrhea and diffuse abdominal discomfort. She reported having five to six bowel movements for two days followed by an additional 15 bowel movements prior to admission. She described that her bowel movements were watery and yellow in appearance. The patient also complained of generalized myalgias and subjective fevers intermittently. She denied any hematochezia, melena, or recent weight loss.\nShe was hospitalized three weeks prior to this admission with similar symptoms. During that time, she was found to have mild colitis and workup including gastrointestinal (GI) polymerase chain reaction (PCR), stool ova and parasites, Clostridium difficile (C.diff) testing by PCR were all negative. The patient was started on a 10-day course of ciprofloxacin and flagyl. The patient stated that diarrhea resolved with the antibiotics, but restarted two days after completion.\nDuring admission, the patient was started on intravenous (IV) fluids and stool samples were collected and sent to the lab. Stool PCR, C.diff, cultures and ova/parasite testing all again came back negative for the second time. Subsequently, a colonoscopy was performed that revealed a solitary five-millimeter ulcer in the cecum (Figure ). Biopsies were taken with cold forceps and histopathological analysis confirmed lamina propria histiocytosis with intracellular microorganisms consistent with histoplasmosis (Figure ). Grocott’s methenamine silver stain and Period acid-Schiff stain were both positive, further confirming the diagnosis of histoplasmosis (Figures -). Subsequently, the patient tested positive for HIV with a CD4 count of 59 and viral load of 140,000. The patient was started on IV amphotericin B with acetaminophen and diphenhydramine premedication. She was also started on a combination of abacavir, dolutegravir and lamivudine daily for HIV infection, sulfamethoxazole/trimethoprim for pneumocystis jiroveci prophylaxis and nystatin for oral thrush. She continued to improve clinically in the hospital and was then discharged home on IV infusion to receive the last three days of amphotericin B to complete a total of 14 days. The patient was then switched to oral itraconazole and scheduled to follow up with an infectious disease specialist.

An adapted imaginal exposure approach to traditional methods used within trauma-focused cognitive behavioural therapy, trialled with a veteran population
|
Mr C was a single man in his 60s. He had served in the UK military police during the Northern Ireland peacekeeping operations in the 1960s. During his service he attended the aftermath of an explosion that had killed several civilians, including a child. Afterwards he experienced an intrusive fragmented image of the scene in his right peripheral field of vision. At assessment he reported experiencing the image every day but avoided focusing on it. He had not spoken about the event to anyone in his life prior to the start of therapy. He identified that his mood state fluctuated between detachment and feeling overwhelmed by anxiety symptoms when confronted by a reminder of the event (e.g. a news item about Northern Ireland). This could lead him to dissociate and therefore he avoided such triggers. He also experienced periods of depression and had previously used alcohol to cope with his difficulties. His avoidance of the trauma memory maintained his PTSD symptoms (). He reported he had not received any previous psychological therapy.\nMr C presented as avoidant of engaging in TF-CBT, and utilized several therapy sessions to discuss his concerns. He identified the appraisal as ‘I won’t be able to cope’. Mr C attempted to use multiple grounding strategies in the therapy room, combining olfactory strategies with standing up and holding an object; however, he either presented as matter of fact and detached from any emotion or unable to tolerate ‘in vivo’ reliving that involved closing his eyes, claiming he felt overwhelmed by physical panic symptoms and he began to dissociate. In both reliving sessions he could not gain access to his peri-traumatic cognitions.

An adapted imaginal exposure approach to traditional methods used within trauma-focused cognitive behavioural therapy, trialled with a veteran population
|
Mr P was a married man in his 40s with one child. He had served in the UK army and was deployed to the Bosnian conflict in the mid-1990s. During his deployment he was stationed at a morgue that had been set up to aid the identification of bodies recovered from a mass burial site. He described how the morgue contained a large number of bodies in various states of decomposition, with varying degrees of physical trauma. He reported re-experiencing fragmented intrusive images of the morgue and daily emotionally distressing nightmares of which he could not recall the content. He experienced high levels of anxiety that triggered his dissociative symptoms. These appeared to function as a coping strategy to avoid distressing emotions connected to his memory of the morgue. Other avoidance symptoms included feeling detached from people around him and feeling emotionally numb. Mr P avoided family occasions and busy places which could trigger his hyper-arousal symptoms and had never spoken to anyone about his experiences. He reported coping historically through the use of alcohol to block out his emotions. His avoidance behaviours had maintained his PTSD symptoms.\nAt the start of therapy sessions, Mr P was reluctant to talk about his past experiences stating he only felt able to discuss vague details about his intrusive memories. Mr P attempted to use physical objects such as stones and leaves, or his e-cigarette, as grounding strategies in the clinic room. However, he also reported feeling unable to tolerate any emotions connected to the events and found it difficult to identify peri-traumatic cognitions. Mr P appeared to experience intrusions of one particular fragmented image and could not recall any other contextual information from before or after this moment.\nIn both cases Mr C and Mr P experienced difficulties in engaging with traditional methods of imaginal reliving and prolonged exposure, due to high levels of avoidance and low thresholds for dissociation, and subsequently had difficulties accessing their cognitions for updating. For both clients the prior use of multiple grounding methods in the therapy room were unsuccessful. They experienced their traumatic memories as fragmented images with a sense of ‘nowness’ (), which indicated a distinct lack of contextualization.\nAn adaptive approach was then trialled to address these hindering factors. This involved three stages: (1) walking the client through the imaginal scene outdoors to address dissociation, (2) viewing the imaginal scene from multiple perspectives to facilitate contextualization of the memory and (3) identifying and reappraising the cognitions with frequently used approaches in trauma-focused therapy.

Olfactory Nerve Schwannoma: A Case Report and Review of the Literature
|
A 56-year-old male patient was presented to the emergency department, one day following a road traffic accident. Full history was obtained and thorough neurological examination was done, the patients Glasgow coma score was 13/15, he had right otorrhea, ecchymosis of both eyes, the right pupil was dilated fixed, and the left one was regular and reactive to light. Patient had history of old orthopedic instrumentation, 30 years ago.\nCT (computed tomography) scan was obtained, which revealed pneumocephalus, and an incidental finding of a right frontal intra-axial mass with aggressive perilesional edema. Patient received conservative management, including dehydrating measures, antibiotics, and prophylactic antiepileptic. Complete investigations showed fracture maxilla and mandible.\nTwo days after admission, patient regained consciousness and re-evaluation showed right sixth nerve palsy, right optic atrophy, and anosmia. We recommended magnetic resonance imaging (MRI) brain with contrast, but it was not possible due to the old fracture and instrumentation, so a CT scan with contrast was done, as shown in\n, and revealed an intra-axial mass with perilesional edema, and a cystic component. Our differential diagnosis was a high-grade glioma, an abscess, or metastatic deposits. Metastatic workup including CT chest, pelvi-abdominal ultrasonography, and tumor markers including PSA,\nα\n-feto protein were all negative.\nExpecting the mass to be intra-axial a right frontal craniotomy with trans-cortical approach was decided. Intraoperatively, palpation of the brain surface revealed no underlying cystic lesion, neither did aspiration, using a brain needle came up with any fluid. We proceeded with the transcortical approach, where a well-defined basal intraparenchymal mass appeared. The mass was reddish, soft in consistency, and was excised completely at the end of the procedure. Postoperative CT scan is shown in\n.\nWe were not able to identify neither optic nerves, nor the olfactory, at the end of our transcortical approach.\nHistopathological examination showed benign spindle-shaped cells, with elongated nuclei and fibrillary cytoplasm (Antoni-A pattern), and less cellular, loosely textured tumor areas,\n.\nPostoperatively, the patient was fully conscious, with improvement of his right sixth nerve palsy, but no improvement occurred in his smell, or right optic atrophy, right sixth nerve palsy, and anosmia.

Prolonged Postoperative Vasoplegia in Pediatric Patients on Chronic Angiotensin II Blocker Treatment
|
A 17-year-old male with Marfan's syndrome and a family history of Marfan's and aortic dissection in one parent, was diagnosed with a dilated aortic root (sinuses of Valsalva 47 mm) with trivial aortic regurgitation. He took candesartan 8 mg every morning including the day of surgery. He underwent a valve-sparing aortic root replacement. Maintenance of normotension during cardiopulmonary bypass required the administration of noradrenaline. Postoperatively he developed severe vasoplegia with a rise in serum lactate to 8.1 mmol/L that responded to treatment with noradrenaline. He did not have any other organ dysfunction and was extubated after 12 h. He required vasoconstrictor therapy for 53 h. He made an uneventful recovery thereafter and was discharged home on postoperative day 8.

Prolonged Postoperative Vasoplegia in Pediatric Patients on Chronic Angiotensin II Blocker Treatment
|
A 14-year-old male with Marfan's syndrome and progressive aortic root dilatation (sinuses of Valsalva 47 mm), moderate mitral regurgitation and significant pectus carinatum, underwent a valve sparing aortic root replacement, aortic valve repair, mitral valve repair and concomitant Ravitch procedure. He took candesartan 4 mg twice a day including the night prior to surgery. Maintenance of normotension during cardiopulmonary bypass required the administration of noradrenaline. Shortly after transfer to the intensive care unit he developed profound hypotension despite fluid boluses and increasing vasopressor doses and required a brief period (2 min) of cardiopulmonary resuscitation. His inotrope requirement included adrenaline up to 0.1 mcg/kg/min, noradrenaline up to 0.08 mcg/kg/min, dopamine up to 10 mcg/kg/min, and vasopressin up to 0.6mU/kg/min. His serum lactate postoperatively increased to 9.7 mmol/l before normalizing over 24 h. There was no evidence of other organ dysfunction. He required vasoconstrictor therapy for 106 h and mechanical ventilation for 72 h after which time he made an uneventful recovery. The clinical parameters and the vasoactive medications used have been summarized in Table .\nBoth patients had gas induction for anesthesia and maintenance using Sevoflurane (Case 1: 1.7% and case 2: 2.9%). Both had a combination of antegrade-retrograde intermittent cold blood cardioplegia instituted and the cardiopulmonary bypass was maintained at normothermia. At the end of the procedure both patients underwent modified ultrafiltration and were transferred to the intensive care unit with a positive fluid balance of 140 and 790 ml respectively.

Clerodane furanoditerpenoids as the probable cause of toxic hepatitis induced by Tinospora crispa
|
A 57-year-old male patient, with no personal or family history of liver disease or alcohol addiction, was admitted for acute hepatitis with cholestasis and cytolysis. Three weeks before, he had started consuming an aqueous extract of “lian-sepent”, a traditional medicine corresponding to T. crispa according to local ethnobotanists. This herbal remedy was supposed to detoxify his liver. It consisted of a piece of T. crispa stem put into a bottle of water and drunk regularly over the next two days. Two weeks later, the patient prepared a similar aqueous extract of T. crispa and consumed it over two days. Following his last intake, the patient felt fever and asthenia for one week and went to the emergency room after occurrence of dark urine. On admission, he suffered from jaundice, was not overweight, and had normal vital signs. Biological tests revealed evidence of hepatocellular damage (ALT 1923 U/L; AST 873 U/L) and cholestasis (γGT 155 U/L). Abdominal ultrasonography was normal with no hepatomegaly or lithiasis. The results of laboratory testing disclosed no serological arguments for viral hepatitis (hepatitis A virus, hepatitis B virus, hepatitis C virus, cytomegalovirus, Epstein-Barr virus and varicella zoster virus). The patient was discharged two weeks after admission and evolution was marked by the regression of jaundice and progressive decrease in liver function tests without any specific treatment (Table ).

Improvement in Frailty in a Patient With Severe Chronic Obstructive Pulmonary Disease After Ninjin'yoeito Therapy: A Case Report
|
A 76-year-old man with severe chronic obstructive pulmonary disease (COPD) presented with a feeling of fatigue, weight loss, and reduced physical activities. He was diagnosed with COPD at the age of 69 years and had retired from work the following year. His smoking history included 40 cigarettes per day between the age of 14 and 69 years; his airflow limitation was classified as severe by the Global initiative for Chronic Obstructive Lung Disease; and a chest computed tomography (CT) scan showed severe emphysema. He had started long-term oxygen therapy at the age of 72 years and is currently inhaling 3 L/min of oxygen. Medical and family histories were otherwise unremarkable. Cardiac ultrasound excluded comorbid congestive heart failure or pulmonary hypertension, and CT pulmonary arteriography also excluded chronic pulmonary thromboembolism. As the patient had a history of acute exacerbations of COPD more than twice a year with extreme respiratory symptoms, he was prescribed a combination of inhaled long-acting antimuscarinic antagonist, long-acting beta2-agonist, corticosteroid, and oral carbocysteine, ambroxol, and theophylline. He reported symptoms of dyspnea on exertion, depression and anxiety, and a decrease in physical activity. He also experienced anorexia with a weight loss of more than 5 kg in a year, and no other possible causes of weight loss, such as tuberculosis and malignant tumor, were observed. Therefore, in addition to respiratory pharmacotherapy, we prescribed an antianxiety drug and provided nutritional supplement therapy, patient education, and pulmonary rehabilitation. However, the patient's mental and physical symptoms did not improve after 4 months. Furthermore, he exhibited deterioration in activities of daily living as well as physical and mental weakness; hospital visits were difficult and therefore, he considered home care. Persistent weight loss, poor endurance and energy, and low physical activity levels led to the diagnosis of physical frailty according to Fried's criteria (). This vulnerability was supported by assessments using the Kihon Checklist (KCL) (), the COPD Assessment Test (CAT) (), and the Hospital Anxiety and Depression Scale (HADS) (), all of which revealed high scores indicating inferior status. The KCL is a tool designed by a study group from the Japanese Ministry of Health, Labor and Welfare and comprises 25 items divided into seven categories: physical strength, nutritional status, oral function, socialization, memory, mood, and lifestyle. The KCL scores range from 0 (no frailty) to 25 (severe frailty); a previous study classified the patients' frailty status as non-frail (0–3), prefrail (4–7), and frail (8–25) (). The CAT is a reliable tool that comprises eight items that assess the various COPD symptoms and is widely used in clinical practice. The CAT scores range from 0 to 40, with a score of 0 indicating no impairment. The HADS is also widely used to measure the level of anxiety and depression and comprises 14 items: 7 associated with anxiety (HADS-A) and 7 associated with depression (HADS-D). The HADS-A and HADS-D scores ranged from 0 to 21, and are in the range 8–10 for doubtful cases and ≥11 for definite cases. For the present case, we continued the pharmacological treatment, nutritional supplement therapy, patient education, and pulmonary rehabilitation and included 2.5 g of Ninjin'yoeito to be taken 3 times a day before meals.\nAfter administration of Ninjin'yoeito, physical examination and blood tests such as electrolytes, liver function tests, and renal function test were performed to evaluate the side effects of Ninjin'yoeito administration. However, no side effects were detected. A significant improvement in symptoms, including increased appetite and alleviation of mood disorders and weight loss, was observed 1 month after initiating Ninjin'yoeito administration. Body weight and muscle mass continued to increase, and after 6 months of Ninjin'yoeito administration, the body weight increased by 8 kg compared with that prior to Ninjin'yoeito administration. Body composition assessed using bioelectrical impedance (InBody 720; Biospace, Tokyo, Japan) showed increasing muscle mass and no change in the body fat percentage (Figure ). The patient's KCL, CAT, and HADS scores increased over time (Figure ), and his status improved from frailty to non-frailty. Written informed consent was obtained from the participant for the publication of this case report.

Microlaryngoscopic surgery for pyriform sinus fistulas in children: a report of two cases
|
A 9-year-old boy presented to our hospital with a history of recurrent neck abscesses since 8 years of age. He had received antibiotics and had undergone drainage of the abscesses in other hospitals. He was admitted to our hospital after control of inflammation. Barium esophagography showed a PSF on the left side (Fig. ). Oral contrast coronal computed tomography (CT) showed an air- and barium-containing fistula (Fig. ). He underwent open neck surgery for definitive treatment of the PSF. He quickly recovered, and he was discharged from the hospital 7 days after the surgery. However, 2 weeks later, he visited our hospital again because of a neck abscess. He received antibiotics and underwent drainage. Barium esophagography revealed fistula recurrence at the same location (Fig. ). As reoperation with the cervical approach was expected to be difficult owing to possible severe adhesions, MLS was planned. Although the internal orifice was detected easily (Fig. ), the fistula was found to be wider and deeper than expected after resection of the fragile layer associated with inflammation (Fig. ). The fistula was resected piecemeal because it could not be easily inverted and peeled off. The entire mucosal remnant was macroscopically removed. Although suturing was difficult because of the wide internal orifice, the procedure was completed uneventfully (Fig. , ). Barium esophagography was performed on the seventh postoperative day, and no issues were noted. He had an uneventful recovery, and he was discharged 10 days after the surgery. No recurrence was observed during an 18-month follow-up.

Microlaryngoscopic surgery for pyriform sinus fistulas in children: a report of two cases
|
A 10-year-old girl presented to our hospital with a history of recurrent left-sided neck swelling since 6 years of age. After control of inflammation, barium esophagography was performed, and it showed a PSF on the left side. CT showed an air- and barium-containing fistula. MLS was performed as first-line treatment. The fistula was narrow, and its tissue was not fragile (Fig. ). Therefore, we made the incision as small as possible (Fig. , ), and the operation was completed uneventfully (Fig. ). Barium esophagography was performed on the fifth postoperative day, and no leakage was noted. Free oral intake was started on the same day. She had an uneventful recovery, and she was discharged 7 days after the surgery. No recurrence was observed during a 10-month follow-up.

Progression of retinal pigmentation mimicking unilateral retinitis pigmentosa after bilateral pars planitis: a case report
|
A 17-year-old man with no known past medical history, presented with 6 months of blurry vision in both eyes. He had no other ocular, medical, or surgical history.\nBaseline visual acuity (VA) was 20/20 in the right eye (RE) and 20/63 in the left eye (LE). His intraocular pressure was normal (17/16 mmHg). Slit lamp examination revealed normal anterior structures and no anterior segment inflammation. A subclinical keratoconus was described in the topography study. 1+ cells in the vitreous (graded on a scale of 0+ to 4+), snowballs and snow banking in the inferior pars plana as well as peripheral vasculitis were observed in both eyes (BE) on dilated fundus examination.\nSerological tests for HIV, Toxoplasma gondii, Borrelia burgdorferi or Treponema pallidum were negative, as well as for antinuclear (ANA) and antineutrophil cytoplasmatic (ANCA) antibodies.\nHe was diagnosed with bilateral pars planitis. Optical coherence tomography (OCT) showed cystoid macular edema in the LE, so that sub-tenon injection of triamcinolone was performed in order to control inflammation, which was slowly reduced.\nSubsequent follow-up visits showed improvement in vision to 20/25 in the LE, resolving progressively the inflammation of the posterior pole although 0.5+ cells were observed in the vitreous cavity. Then, no additional therapy was needed. Nonetheless, the patient complained of loss of visual field in his LE.\nIn-depth fundus examination showed a mild, diffuse, granular appearance of the retinal pigment epithelium (RPE) throughout the LE. Progressive, intraretinal bone crepuscule pigmentation developed during the following three months (Fig. ). The RE showed no retinal pigmentation. Humphrey perimetry confirmed peripheric constriction of the visual field in the LE and no scotomas in the RE.\nAn electroretinogram (ERG) showed subnormal response only in the LE. The diagnosis of unilateral RP-like appearance was made.

Paraneoplastic immunoglobulin A nephropathy and associated focal segmental glomerulosclerosis in asymptomatic low volume B-cell lymphoma – a case report
|
In October 2014, a 53 year old male Caucasian administration officer was referred to a tertiary renal outpatient clinic for assessment of nephrotic range proteinuria. On review, he described occasional ankle oedema over the past year but otherwise felt well. His past medical history was significant for type 2 diabetes mellitus which was treated in 2007 with 15 kg of weight loss (glycosylated haemoglobin < 6% since 2013). He denied symptoms of macrovascular or microvascular complications. The patient also had hypertension (diagnosed > 10 years prior to review), obesity (body mass index: 47.6 g/m2) and degenerative spine disease. His medications were irbesartan 300 mg once daily, hydrochlorothiazide 25 mg once daily, tramadol 50 mg three times a day and meloxicam 7.5 mg as needed. His family history was significant for type 1 diabetes mellitus in his father and paternal uncle. On examination, his blood pressure was 140/80 mmHg and heart sounds were dual with no murmurs. There was bipedal oedema up to the bottom third of his shins, his jugular venous pressure was not elevated and his chest was clear to auscultation.\nInitial laboratory investigation demonstrated haemoglobin 149 g/L, white cell count 7.20 × 109/L, platelets 235 × 109/L, blood urea nitrogen 6.0 mmol/L, serum creatinine 70 μmol/L and serum albumin 32 g/L. Serum electrolytes, liver enzymes, calcium and phosphate were within normal range. Repeated urinalysis did not demonstrate any haematuria, leukocyturia or casts. Urine protein creatinine ratio was 662 mg/mmol (normal in August, 2012, Fig. ). Serum levels of antinuclear antibody, antineutrophil cytoplasmic antibody, immunoglobulin (Ig) A, cryoglobulins, complement factor C3 and C4 were normal. Human immunodeficiency virus screen, Hepatitis B antigen and hepatitis C antibodies were negative. Serum κ free light chains (FLC) was 18 mg/L (7–22), serum λ FLC was 60 mg/L (8–27) and κ/λ ratio was 0.30 (0.31–1.56). Repeated serum electrophoreses over three months showed persistent κ and λ IgG bands in trace amounts consistent with an inflammatory or reactive pattern. The repeated abnormal serum electrophoreses in the absence of inflammation (normal erythrocyte sedimentation rate and C-reactive protein levels) prompted referral to haematology for further assessment.\nBone marrow biopsy showed normocellular marrow with mild lymphocytosis but no morphological evidence of plasma cell myeloma. Flow cytometry identified a clonal B-cell population suggesting a low grade B-cell lymphoma. Staging computer tomography scans of his neck, chest, abdomen and pelvis found some borderline mesenteric lymphadenopathy (clinically stage 1).\nThe first renal biopsy demonstrated 4 glomeruli with minor mesangial hypercellularity but not expansion of the mesangial matrix. However, there was insufficient tissue to determine the cause of the patient’s glomerular disease. The second renal biopsy was performed a month later, yielding 11 glomeruli (Fig. ). There was mild mesangial expansion but no mesangial hypercellularity, endocapillary proliferation nor crescent formation. One glomerulus was globally sclerosed. Three glomeruli showed areas of segmental sclerosis and adhesion to Bowman’s capsule. The lesions of segmental sclerosis were not perihilar in location. There was mild tubular atrophy involving 5% of the cortex and there was mild arteriolar hyalinosis. Immunofluorescence examination showed mesangial reactivity for IgA (moderate intensity), IgM (trace) and both kappa and lambda light chains (weak intensity). There was no reactivity for IgG, C3 or C1q. Electron microscopy showed extensive epithelial foot process effacement with microvillous change. A few small electron-dense deposits were found in the mesangium but not in glomerular capillary walls. Together, these findings indicated IgAN with associated FSGS.\nIn June 2015, the patient began 6 cycles of chemotherapy with cyclophosphamide (day 1: 750 mg/m2), rituximab (day 1: 375 mg/m2) and prednisolone (days 1–5: 50 mg/day). The patient did not demonstrate any side effects or complications from treatment. At the end of chemotherapy, the patient was in complete remission haematologically and urine protein creatinine ratio had decreased substantially to 241 mg/mmol creatinine. Over the next 14 months, his urine protein creatinine ratio continued to fall. His serum creatinine was 104 μmol/L, serum albumin was 38 g/L and urine protein excretion was 14 mg/mmol at his most recent follow-up, 26 months post-chemotherapy.

Synchronous anal canal carcinoma in a heterosexual couple
|
A 60-year-old woman sought medical attention after a 2-month history of minor rectal bleeding and an anal nodule. On physical examination, a 3-cm mobile anterior ulcerative mass in the anal canal was palpable, beginning at 1 cm from the anal verge with no extension to the anorectal junction. No nodes were appreciated in the inguinal regions. A biopsy revealed an invasive squamous cell carcinoma, well-differentiated (Fig. ). Staging computerized tomography (CT) of the thorax/abdomen/pelvis did not show any lymphadenopathy or distant metastatic disease. Pelvic magnetic resonance imaging (MRI) demonstrated a 3-cm mass in the anal canal extending to the anorectal junction (Fig. and ). There was no pelvic or inguinal lymphadenopathy. Her laboratory investigations including HIV-1 and HIV-2 serology were negative. A recent Papanicolau smear of the cervix was reported to be negative for intraepithelial lesion or malignancy.\nThe patient had a past medical history remarkable for an in-situ cervical carcinoma treated with laser therapy over 20 years ago with no subsequent recurrence. She also underwent a right salpingo-oophorectomy for an endometriotic cyst of the right ovary 8 years prior to her anal canal cancer diagnosis. She is a life-time non-smoker and social alcohol drinker. There was no past history of any autoimmune disorders.\nFor her T2N0M0 anal cancer, the patient underwent a course of chemo-radiotherapy as per institutional protocol. The total dose was 54 Gy in 30 daily fractions to the primary and elective nodal irradiation consisted of 36 Gy in 20 fractions to the inguinal/femoral, mesorectal, presacral and external/internal iliac nodal regions. The radiation treatment was delivered using volumetric modulated arch therapy (VMAT) technique. The chemotherapy regimen consisted of mitomycin C (10 mg/m2 on day 1) and infusional 5-fluorouracil (1000 mg/m2/day for 4 days), given concurrently on week 1 and week 5 of radiation. The patient developed RTOG grade 3 skin and perineal reactions. She had an episode of fever without neutropenia managed by oral antibiotics.

Using donor human milk to feed vulnerable term infants: a case series in KwaZulu Natal, South Africa
|
Baby G arrived at ITL in 2015 when he was one-day-old weighing 1.9 kg. His mother had concealed her pregnancy. The baby boy was fed with DHM from the day of arrival. He was switched to infant formula in November and December 2015, when supplies of DHM ran out; however, he did not tolerate the artificial substitute well and began vomiting after feeds. When DHM was available again in January 2016, his condition improved, the vomiting stopped and he gained weight once again. He was adopted at six months weighing 7.4 kg (Fig. ).

Ivermectin-induced fixed drug eruption in an elderly Cameroonian: a case report
|
A 75-year-old man from the South-West Region of Cameroon (an endemic zone for onchocerciasis) and of Bamileke ancestry presented to our clinic with skin lesions that had been evolving for over a year. The eruptions were first noticed a few hours after he took 12 mg of ivermectin (Mectizan) during mass drug administration (MDA) campaigns carried out every 3 months (as part of the public health strategy and in line with a recommendation from the World Health Organization’s African program for control of onchocerciasis [] and to fight against filariasis in endemic parts of Cameroon). The initial eruptions were dark, itchy discolorations with occasional burning and appeared as single isolated rashes on his groin, genital, and neck regions.\nOn further inquiry, he described similar symptoms in the past whenever he took ivermectin which disappeared after he stopped the drug. Further consumption of ivermectin (2 months prior to consultation) during the ensuing campaign resulted in worsening of the old lesions with development of multiple new lesions over his face, back, and extremities. His family and medical history were not remarkable for any previous drug or cross-reactivity reactions.\nOn physical examination, he looked well with vital signs within normal limits. There were multiple well-defined circular erythematous hyperpigmented plaque lesions of sizes ranging from 1 × 3 cm to 7 × 10 cm on his face, neck, groin area, and both extremities (Fig. ) occupying approximately two-thirds of his total body surface area (TBSA). Other systemic examinations were normal.\nA laboratory work-up including full blood count, human immunodeficiency virus (HIV) serology, urine analysis, and biochemistry (liver and kidney function tests) were normal. Erythrocyte sedimentation rate was at 65 mm/hour after the first hour, while punch biopsy of the skin, and antinuclear antibodies (ANA)/antineutrophil cytoplasmic autoantibody (ANCA) were requested but were unavailable.\nA working diagnosis of FDE was made based on clinical signs and patient history despite the lack of histopathological findings.\nDiscontinuation of ivermectin (plus counselling on avoidance of other possible culprits), a short course of systemic corticosteroids (prednisone 60 mg daily for a week), and orally administered antihistamines (hydroxyzine 75 mg daily) were employed as treatment modalities. Close patient follow-up revealed marked regression of lesions within a fortnight with residual hyperpigmentation (Figs. and ).

A 10-day-old male crossbred (Frisian x local indigenous) calf presented with a severely distended abdomen (Fig. ). Due to the distention the paralumbar fossa, especially on the left, was not visible. The calf was reluctant to suckle from the dam, unable to walk, exhibited rapid and shallow breathing, and had visibly congested mucus membranes. Percussion of the left abdomen revealed a drum-like gaseous sound. On auscultation of the left abdomen, a dull fluid sound was detected. The anamnesis indicated that the calf had been dribbling urine continuously, unable to defecate, or had irregularly voided very little, hard, and pasty feces. General physical examination revealed no esophageal obstruction, but the calf was weak and with an abnormal gait. The calf was suckling its dam twice in a 12 h interval (at morning and evening) and had not started feeding the hay/roughage/concentrate or the calf starter at the moment. The physiological parameters of the calf were as follows: Rectal temperature = 39.8 degree Centigrade (°C), Pulse =175 beats/minute, Respiration =60 breaths/minute.\nAbomasal bloat and choke.\nIn order to release trapped gases and check the patency of the esophagus, a flexible stomach tube coated with mineral oil was inserted into the esophagus, and advanced down into the rumen. A fermented watery-like fluid accompanied by some clots of milk and gases was released from the rumen through the stomach tube. Procaine penicillin (Pen Aqueous; Zoetis Canada), 10 ml (ml), 10,000 international unit per milliliter (Iu/ml of solution) mixed with 0.25Liter (L) of mineral oil was administered orally for 3 days, while milk was withheld to reduce the microbial burden and coalescence of gas. An isotonic solution containing 0.9% Sodium Chloride (Jiangsu HFQ Bio-Technology Co., Ltd), 8.4% Sodium Bicarbonate (Vet One, Nova-Tech, Grand Island, USA) and 5% Dextrose in water 1000 ml injection (Addis Pharmaceutical factory) was administered intravenously (IV) at a rate of 100 ml/kilogram (kg) over 3–5 h for 2 days. Before administration of IV fluid, the calf was sedated using Xylazine hydrochloride, 20 mg/ml (xylazine® immunological LTD, Hyderabad, India) intramuscularly (IM). This was administered during every fluid therapy, and the calf was tied up with rope in a lateral recumbent position. The hair around the jugular groove of the neck was clipped and the area was cleaned and disinfected using diluted 70% Ethanol (Addis Pharmaceutical factory). The superficial jugular vein was catheterized using 20 Gage, 0.8 in. butterfly catheter (Unolok, Hindustan syringe, Medical device LTD Faridabad, India) and secured with adhesive tape around the neck.\nAfter 3 days of treatment, bloat reoccurred. Treatment was initiated a second time by giving antibiotic pen strep (Pen & Strep@, 100 ml, York Vet, USA): 5 ml, (IM), every 24 h (q24hrs) for 2 days while the calf had been fastening. Additional supportive therapy of 40% glucose (100 ml/kg/day IV), isotonic saline solution (10 ml/kg/hrs IV) and a multivitamin (Multivitamin injection 100 ml, Norbrook Laboratories Limited, Ireland), was administered 10 ml IM once at a time (Stat.) during the time that the milk was withheld. After 2 days of treatment, the calf was allowed to suckle milk from the dam; however, the calf exhibited bloat again 5 h after milk consumption.\nRuminal fistulation (rumenostomy) was conducted to prevent recurrence according to a procedure described by Turner and Mcilwraith []. Before the surgical procedure milk was withheld from the calf overnight while IV fluids and glucose were administered at the dose rate explained above. The left paralumbar fossa was prepared by shaving the hair and washing skin aseptically using 7.5% povidone-iodine surgical scrub (Povidone-iodine cleansing solution, Wockhard LTD, Mumbai, India) while the calf was standing. A circular area of 6 cm (cm) in diameter just below the transverse process of the lumbar vertebrae was marked and infiltrated with local anesthetic, 2% Lidocaine (Zoetis Canada, Kirkland,Quebec), at the concentration of 20 mg per milliliter (mg/ml). Approximately a 2 cm diameter circular incision was made to remove the skin. After skin removal the abdominal muscles were dissected bluntly to expose the rumen. The rumen was grasped using sponge forceps and pulled to the exterior. The rumen wall was then tacked to the edge of the skin by four horizontal mattress sutures at “quarter hour” positions (12, 3, 6 and 9 o’clock). These sutures acted as stay sutures using a non-absorbable suture (Sofsilk™ 6–0 Black, Medtronic, USA). The rumen wall was incised carefully at one half centimeter from the wound margin/apposing skin. As the contents of the rumen came out during the procedure, we observed a high amount of milk that had entered into the rumen (Fig. ).\nThe calf was separated from the herd for 10 days to maintain close observation. Since rumenostomy is considered a clean contaminated surgery, we had to give parenteral antibiotic, penstrep, (Penstrep-400, Metaalweg, 85,804 CG Venray, Netherlands) 5 ml for 4 days, q24hrs IM to reduce the risks of peritonitis. A dexamethasone injection at 2 mg/ml (Sparhawk laboratories Inc., Lemexa, KS66215, USA) was given every eight hours (q8hrs) IM, and also served as an anti-inflammatory agent. Moreover, Deltamethrin 1% (w/v) pour-on ready-for-use formulation (Appropriate Applications Ltd., USA) at a dose rate of 10 ml per 100 kg body weight was used to prevent insect infestation and miyiasis. The surgical wound was examined and monitored every day until closure for any complications such as wound dehiscence or rumen attachment to the skin. Rumen contents leaking out onto the flank area and outer surgical site were cleaned by using antiseptic solution (Chlorhexidine) and clean towels. The rumen was repeatedly flushed through the fistula with 0.5–1 l of warm tap water adjusted to the calf’s body temperature. This flushing helped to prevent desiccation and was used for buffering purpose. The calf was allowed to suckle milk from its dam twice a day during the follow-up period. After 10 days post-operation, the calf was provided with some hay and fresh grasses to stimulate rumen function. Bloat resolved by the time the calf started solid feeds and the wound was closed surgically just after a week of feeding grasses and hay.\nThe calf was followed for 6 months after the procedure. Shortly after wound closure, the amount of milk that the calf was getting was reduced to encourage the intake of hay and grasses. During this time, bloat did not occur as it had been observed prior to surgery. Although ruminal contents spilled onto the flank post-operatively, this did not appear to upset the calf, and its general condition improved gradually. We recommended that the owner reintroduce the calf with the existing herd 6 months after the surgery, and advised the owner to inform us of any observable complications. We promised the owner that we would visit the calf at one year; however, the owner had sold the calf at 9 months of age to a beef farmer in another area of the country.

Late presentation of Torsades de Pointes related to fluoxetine following a multiple drug overdose
|
A 61-year-old woman with a past medical history of type II diabetes, breast cancer, and major depression presented to the emergency department after an intentional overdose with fluoxetine (139 tablets of 20 mg), risperidone (6 tablets of 1 mg), bromazepam (90 tablets of 3 mg), zolpidem (40 tablets of 10 mg), naproxen (20 tablets of 500 mg), and clemastine (5 tablets of 1 mg). Quantities were determined by counting the remaining pills in the blister packaging. Upon arrival, the patient was somnolent but able to open her eyes on request (E3M6V5). Vital signs showed a blood pressure of 146/57 mmHg, a regular heart rate of 55/min with strong peripheral pulsations, a respiratory rate of 16/min, oxygen saturation levels varying between 95 and 100% at room air, and a body temperature of 36.2 °C. Her husband suggested that the pills must have been ingested 3 to 8 h prior to hospital admission. Electrocardiography (ECG) showed a sinus rhythm of 61 beats per minute with a prolonged corrected QT interval (QTc) of 503 ms as shown in Fig. . During admission, all ECGs were performed using a GE MAC 5500 HD electrocardiograph. The tangent method was used in order to define the end of the T-wave in the lead with the longest QT interval. All measured QTc intervals were corrected for cardiac frequency using Bazett’s formula [].\nInitial laboratory findings showed a microcytic anemia (Hb 5.4 mmol/l, MCV 77 fl) with low serum ferritin (6 μg/l), along with a mild leukocytosis of 11.2/nl. Serum electrolytes, as well as liver and kidney function, were normal (Na+ 135 mmol/l, K+ 4.3 mmol/l, creatinine 89 μmol/l, corrected calcium 2.37 mmol/l, PO43− 1.41 mmol/l, magnesium 0.83 mmol/l). Arterial blood gas analysis showed a base excess of − 4.9 mmol/l (pH 7.37, pCO2 4.6 kPa, pO2 12.1 kPa, HCO3− 20 mmol/l). A chest X-ray displayed no aspiration pneumonia nor other cardiopulmonary anomalies. The patient was admitted to the ICU for observation, where she received intravenous fluids along with 40 mg of pantoprazole for the prevention of peptic ulcer disease due to the substantial ingestion of naproxen. This was administered only once due to the risk of further QTc interval prolongation. Initially, our patient remained hemodynamically stable and showed improved neurological function. Twenty-two hours after hospital admission, a second ECG showed normalization of the QTc interval to 458 ms, suggesting peak serum levels of the ingested drugs had passed. After psychiatric evaluation had taken place, our patient had fallen to the floor in search of the restroom. On examination, both her muscle strength and coordination were slightly disturbed. Due to the overall severity of the intoxication and the persistence of neurological symptoms, it was decided to observe the patient for one more night at the ICU. Flumazenil was not administered since the patient was fully conscious and already in a monitored environment and due to the risk of adverse effects, especially with chronic benzodiazepine use [].\nThat night, 36 h after admission, our patient developed recurrent short episodes of Torsades de Pointes (TdP) with intermittent loss of cardiac output, as shown in Fig. . Two grams of magnesium sulphate was administered intravenously, after which sinus rhythm was restored. Four hours later, she had complete loss of circulation, after which cardiopulmonary resuscitation was initiated according to protocol. A 150-J biphasic shock was delivered using an automated external defibrillator (Zoll R-Series ALS). ECG findings consistent with TdP were again observed. Spontaneous circulation was restored after intravenous administration of magnesium sulphate. Our patient was awake and immediately able to maintain a patent airway following the incident. Serum levels of fluoxetine and risperidone and their metabolites were measured in retrospect, as shown in Table and Fig. , . Laboratory findings at the time of the incident showed a mild hypocalcaemia of 2.10 mmol/l with a hypermagnesaemia of 1.72 mmol/l/, most likely caused due to the prior administration of magnesium sulphate. No other electrolyte abnormalities were identified (Na+ 137 mmol/l, K+ 3.8 mmol/l, PO43− 1.24 mmol/l). Subsequent ECGs showed progressive prolongation of the QTc interval up to 565 ms, as shown in Fig. . The patient remained hemodynamically stable for the remainder of the night on continuous infusion of magnesium sulphate (1 g/h). The following day, echocardiography was performed in order to exclude structural cardiac defects, which showed normal heart dimensions as well as a normal left and right ventricular function.

Basal cell adenocarcinoma of the nasopharyngeal minor salivary glands: a case report and review of the literature
|
In August 2010, a 57-year-old Chinese male presented with epistaxis and decreased hearing for 1 month. No additional symptoms, such as a neck mass, nasal obstruction, headache, diplopia or other cranial nerve palsies, were noted. The patient had no history of previous or synchronous tumours or any family history of cancer. Nasopharyngoscopy revealed a large exophytic tumour that was covered by smooth mucosa, which grew from the right posterolateral nasopharyngeal wall in the right posterior naris. Magnetic resonance imaging (MRI) scans of the nasopharynx and neck using gadolinium enhancement demonstrated a 2.0 × 1.5 × 2.0 cm well enhanced mass over the right posterior nasopharynx with right retropharyngeal node enlargement. The tumour extended across the right parapharyngeal space and infiltrated into the medial pterygoid muscle. In addition, skull base erosion was detected with right alar lamina involvement (Fig. ). Cervical lymph node metastasis was not observed. Hematologic, hepatic and renal function tests revealed no abnormalities. The patients underwent chest and abdomen computed tomography (CT) as well as a bone scintigram, and no distant metastasis was found. A biopsy of the nasopharynx was performed.\nIn the biopsy specimen, normal salivary tissue was not present. The tumours were ill demarcated without encapsulation. Tumour cells were arranged in nests and nodules. Two morphologic patterns of the tumour cells were observed. Some small round cells exhibited dark nuclei and scant cytoplasm. Other large cells contained round to oval pale nuclei and eosinophilic to amphophilic cytoplasm. In the central region of the tumour cell nests, large cells displayed a solid growth pattern. Small dark cells were clustered at the periphery of the tumour cell nests and appeared palisaded. Prominent nucleoli and mitosis can be observed, and an average of three mitotic figures were observed per 10 high-power fields (original magnification × 400).\nIn the immunohistochemical analysis, the tumour cells were immunoreactive with P63, vimentin, and cytokeratin (CK7 and CK14) antibodies and focally immunoreactive with a calponin antibody. This case of BCAC was not positive for smooth muscle actin or CD117. The proliferative index as demonstrated by Ki-67 was approximately 10%. Based on the immunohistochemistry results and the pathological findings, which included tumour islands with solid proliferation, basaloid-like cells containing large pale and small dark cells, an infiltrative margin, cellular and nuclear pleomorphism, and prominent mitosis, the patient was diagnosed with a solid-type minor salivary gland BCAC (Fig. ).\nBased on the 2002 American Joint Committee on Cancer (AJCC) Tumor, Node, Metastasis (TNM) staging system [], the tumour was classified as stage III (T3N0M0).\nIn our case, the patient received intensity-modulated radiation therapy (IMRT) with 6 MV X-rays. The delineation of the gross tumour volume (GTV) was based on the primary tumour volume determined from the physical and imaging examinations. The clinical target volume (CTV) was defined as the whole nasopharyngeal cavity, the clivus, the skull base, the pterygoid plates, the parapharyngeal space, the sphenoid sinus, the posterior one-third of the nasal cavity, the maxillary sinus, and the drainage of the upper neck (levels II, III, and Va. A total dose of 70.4 Gy/32 F/6.2 W was administered based on the planning target volume (PTVg) (GTV with 0.5 cm margin). The PTV60 was defined as 60 Gy/30 F (CTV with 0.5 cm margin) (Fig. ). After radiotherapy, MRI and nasopharyngoscopy revealed complete disappearance of the tumour (Fig. ). The patient was followed up every 3 months for the first 2 years, every 6 months for another 3 years, and then every 12 months. A follow-up at 72 months did not detect any evidence of disease recurrence. The patient developed moderate mucositis as an acute adverse event. However, he did not exhibit any grade 3/4 late adverse events, such as xerostomia, dysgeusia, or hearing impairment.

Yellow nail syndrome with chylothorax after coronary artery bypass grafting
|
A 62-year-old man with coronary artery disease underwent four-vessel CABG including left internal thoracic artery (ITA) to left anterior descending artery. The patient was discharged on postoperative day (POD) 6 after an uneventful postoperative course with low chest tube output and trace pleural effusions.\nOn POD 13, the patient was readmitted after four days of moderate chest pain and exertional dyspnea. Diminished respiratory sounds were noted over the full left lung field. Chest radiograph confirmed a large left pleural effusion (Fig. ). A left pigtail catheter drained 2.3 l of milky fluid with a triglyceride level of 1604 mg/dL, diagnosing chylothorax.\nConservative management was attempted with continued catheter drainage and initiation of a low-fat diet with medium-chain triglycerides on POD 14. Drainage gradually decreased over the next three days to < 100 ml/day, but by POD 18, drainage increased to 350 mL/day that continued for two days despite attempts to readjust the catheter position. On POD 20, the pigtail catheter was replaced with a chest tube, and the patient was transitioned to total parenteral nutrition (TPN) and octreotide while nil per os, but chest tube drainage persisted at 200–360 ml/day. On POD 28, the patient noted new, bilateral yellow toenail discoloration (Fig. ). The yellow nail discoloration was not associated with any disfiguring features such as nail thickening or separation from nail bed. No lymphedema was found. Presence of yellow nails and chylothorax resulted in diagnosis of YNS.\nLymphangiogram on POD 32 noted well-opacified pelvic lymphatic channels, but cisterna chyli and thoracic duct were not identified (Fig. ), precluding embolization. Tiny droplets of lipiodol were present in the left pleural space, but the leak location could not be identified.\nOn POD 33, thoracoscopic left pleurodesis was performed using aerosolized talc (4 g). Prior to talc administration, half-and-half (300 mL) was administered via nasogastric tube, but no chyle leak was found on thoracoscopic examination after two hours. Since lymphangiogram did not identify a thoracic duct, thoracic duct ligation was not attempted. Five days after pleurodesis, since chest tube output remained high (> 200–300 ml/day), doxycycline pleurodesis was performed via existing chest tube. Output subsequently decreased, allowing transition to low-fat diet seven days later and discharge home two days after that.\nAt 2- and 8-week follow-ups, chest radiograph showed trace pleural effusion with no recurrence of chylothorax. Although still on a low-fat diet at both visits, the patient was gradually increasing fat intake. Yellow toenail discoloration had resolved by the 8-week follow-up.

Atypical onset of nephropathic infantile cystinosis in a Russian patient with rare CTNS mutation
|
The patient was a 2-year-old boy from Russian republic of Ingushetia. Both parents and younger sibling (female) were asymptomatic. Family history is not burdened. Parents may be related, as the mother of the child and the grandmother (father's line) are from neighboring villages of Malgobek region of Ingushetia.\nThe patient is the first child of healthy parents. Pregnancy proceeded against the background of gestosis in the first and second trimester, threats of interruption for a period of 12 weeks, anemia, and lack of hydration. The child was born as a result of fast unassisted childbirth. His birth weight was 3570 g and height was 55 cm. Apgar scores were 6/7. Early motor development slightly delays: He attained head holding at 3 months, sitting without support at 6 months, by the year the boy got up and walked with support. From the age of 8 months, the baby had a weight loss of 2 kg for 2 months with episodes of repeated vomiting. At the age of 1 year 2 months against a background of acute respiratory viral infection, there was a regress in development—the boy stopped walking. Subsequently, rachitic skeletal changes, an increase in the volume of the abdomen appeared, and a loss of motor skills progressed. Magnetic resonance imaging (MRI) of brain revealed a mildly expressed leukopathy in white matter of parietal lobes. Proteinuria and glucosuria appeared at the age of 1 year 8 months.\nAt the age of 2 years 2 months, he was admitted to Russian children's clinical hospital with psychomotor retardation and treatment resistance. On physical examination, he was observed to have a pronounced delay in psychomotor development (he did not get up, walk, crawl; he could only keep his head and turn over). Neurological examination revealed muscular hypotrophy, tendency to hypotension in axial musculature, and uniform decrease in tendon reflexes from hands and feet. MRI of brain revealed subatrophic changes, moderate expansion of the lateral ventricles within the subatrophy with compensated liquorodynamics, and the presence of hypomyelinization zones in the periventricular white matter of the posterolateral regions.\nClinical exome sequencing was carried out by Genotek Ltd. Genomic DNA from peripheral blood sample was extracted using QIAamp DNA Mini Kit (Qiagen, Hilden, Germany). DNA libraries were prepared using NEBNext Ultra DNA Library Prep Kit for Illumina (New England Biolabs, Ipswich, Massachusetts, USA) with adapters for sequencing on Illumina platform. Double barcoding was performed by PCR with NEBNext Multiplex Oligos for Illumina kit. Quality control of DNA libraries was carried out using Bioanalyzer 2100 (Agilent Technologies, Santa Clara, California, USA). We used SureSelect XT2 (Agilent Technologies, Santa Clara, California, USA) for target enrichment. Enriched samples were sequenced on Illumina HiSeq 2500 using pair-end 100 base pairs reads. After sequencing, we trimmed 3′-nucleotides with read quality below 10 using Cutadapt. Raw reads were aligned to reference genome hg19 (GRCh37.p13) using BWA MEM. Deduplication of reads was carried out using SAMtools rmdup. FastQC was used for data quality control. We called short variants using GATK HaplotypeCaller according to GATK Best Practices DNA-seq. The effect of each mutation was assessed using snpEff. To assess pathogenicity and conservatism, the data were extracted from the dbNSFP, ClinVar, OMIM database, and HGMD, as well as using the SIFT and PolyPhen-2 utilities to predict pathogenicity of the mutation. Information on the frequency of mutations was taken from 1000 Genomes project, ExAC, and Genotek frequency data. Description of mutations and their pathogenicity was predicted according to the Standards and Guidelines developed by ACMG (American College of Medical Genetics and Genomics), AMP (Association for Molecular Pathology), and CAP (College of American Pathologists). Copy number alterations were determined using CNVkit. CTNS variant identified by exome sequencing was confirmed by Sanger sequencing of patient, parental, and sibling DNA samples.\nAfter exome sequencing, on admission in Veltischchev Research and Clinical Institute for Pediatrics, patient was 9 kg in weight and 80 cm in height, with low weight-for-height proportion and disharmonious physical development. Deficiency of subcutaneous fat was noted. Attention was paid to rachitic changes in skeleton: expansion of metaphyses, keel-like deformation of thorax, rachitic “rosary,” varus deformity of lower limbs. Hepatosplenomegaly was noted: liver and spleen protruded from under edge of the costal arch by 2.5 cm. Clinical signs include polyuria and polydipsia (consumed liquid per day 1300 mL, daily diuresis—1300 mL). Blood tests showed mild anemia, hypokalemia, decrease in uric acid, increase in alkaline phosphatase activity, hypophosphatemia, increase in triglycerides, and creatinine level at the lower limit of the norm. The study of equilibrium of acids and bases of blood revealed metabolic acidosis. Test of thyroid gland hormonal profile showed subclinical hypothyroidism. Level of cystine in leukocytes was normal. Glomerular filtration rate (GFR) (97 mL/min) was within the normal range (80-120 mL/min). Urine test showed phosphaturia, glucosuria, and low molecular weight proteinuria. Cystine was detected in urine test. Ultrasound examination showed hepatosplenomegaly, multiple foci of increased echogenicity in liver, nephromegaly with thickening, and diffuse changes in renal parenchyma. Radiologic examination revealed pronounced osteoporosis, lagging behind bone age. Ophthalmoscopy revealed cystine crystals in the cornea. Thus, the child has signs of infantile form of nephrotic cystinosis with preserved kidney function.\nThe patient was commenced on cysteamine (Cystagon), initially 50 mg orally four times daily, to increase gradually to 100 mg four times daily (0.8 g/m2/d). Also he was commenced on ophthalmic solution Cystadrops (one drop six times daily) and potassium, phosphorus, vitamin D, energotropic agents. After 6-month therapy, the patient's condition remains stable and serious with slight positive dynamics. The child gained 1 kg in weight and grew by 0.5 cm. Polydipsia/polyuria decreased to 1000-1200 mL. Hemoglobin and red blood cell levels, and thyroid-stimulating hormone and T4 levels were normalized. Minimal phenomena of metabolic acidosis persist. Also, filtration function of the kidneys was preserved, and no signs of nephrocalcinosis were detected.\nAt the last examination, patient had elevated cystine level in the granulocytes (2.32 nmol) and nephrocalcinosis of both kidneys. Cysteamine dose was increased to 1.25 g/m2/d.

Massive air embolism as a complication of upper gastrointestinal endoscopy: A case report illustrating a stroke mimic, literature review, and suggested management
|
A 42-year-old healthy man, with a previous episode of food impaction and increased number of eosinophils in esophageal biopsies taken during an index upper endoscopy 6 weeks earlier, underwent outpatient control gastroscopy after receiving proton pump inhibitor treatment. The upper endoscopy was performed under conscious sedation with midazolam, with a standard video endoscope and the air pressure setting on the video processor at “medium.” Biopsies from distal, middle, and proximal esophagus were taken according to standard protocol. At the end of the 7-minute-long procedure, just after biopsies from proximal esophagus was taken, the patient's heart rate decreased to 46, the oxygen saturation decreased to 90%, and he developed generalized tonic-clonic seizures. The endoscope was rapidly withdrawn, and the oxygen saturation and heart rate normalized spontaneously. However, the patient was unresponsive despite reversal with flumazenil. While hemodynamically and respiratory stable, he remained unresponsive, Glasgow Coma Scale (GCS 3), with pupils midsize, equal, and reactive to light, and a negative Babinski sign.\nAn immediate computed tomography (CT) scan 30 minutes postinitial symptoms revealed massive air embolism in the right hemisphere. (Figure A). The radiologists first suspected infarctions, which was later modified. A complementing CT angiography (CT-AI) was performed 70 minutes after the initial CT scan to rule out differential diagnoses, and the delay was due to recurrent seizure and intubation. The most striking finding was complete resolution of air in the vessels. (Figure B).\nSimultaneously with the CT-AI, a CT of the thorax was performed showing air around the whole length of the esophagus and small amounts of free air in the mediastinum behind the left atrium. (Figure ).\nThe neurologist on call contacted the hyperbaric unit, and the patient was transported to the hyperbaric unit, arriving three hours after initial symptoms. HBOT with United States Navy (USN) (Table 6 (Figure A)) was commenced immediately. The patient remained completely unresponsive during the initial 20 minutes of compression despite a confirmed gas embolism, and to maximize the therapeutic effect, the treatment table was extended to 8 hours and 5 minutes. (Figure B). After initial HBOT, the patient underwent a second CT scan, 12 hours after the initial CT, which to our surprise showed normalization, with only slight reduced attenuation in the right parietal area (Figure A). As the patient remained unconscious and there was a concern of much more damage to the brain than evident on the CT, a magnetic resonance imaging (MRI) was performed. The indication for early MRI performed 14 hours after air embolism was to make an estimation of putative ischemic lesions with diffusion weighted imaging.\nDiffusion weighted MRI indicated cytotoxic edema, predominantly in the areas previously showing the greatest amount of air embolism on the initial CT scan (Figure B). The findings should be interpreted with caution and could be partly reversible.\nA wake-up examination was performed, but since the patient remained GCS 3, neurosurgical monitoring was commenced with intracranial pressure (ICP) monitoring, microdialysis, and continuous electroencephalography (EEG). The patient was continuously monitored and received additional daily HBOT 2.8 ATA, 113 minutes for 4 days. ICP was stable until day 5, but then, ICP instability and suspicion of status epilepticus required treatment with pentothal at burst suppression until day 10. As the patient presented with seizures, levetiracetam was prescribed with an initial dose of 1000 mg 12 hourly. Levetiracetam concentration was checked and dose increased to 1250 mg 12 hourly due to low serum concentrations and suspected epileptic activity on EEG. After 2 weeks, the patient had no seizures, and during the rehabilitation phase, levetiracetam was discontinued.\nA second MRI was performed after 1 week showing progression with severe swelling bilaterally, but most pronounced in the white matter of the right hemisphere (Figure ). During the hospital stay of 3 weeks, the patient was examined with extensive radiology. A series of four brain CT scans, one CT angiography of the brain and neck arteries, five CT of the thorax/esophagus/pulmonary arteries, and three MRI scans of the brain was performed together with a few chest X-rays and ultrasounds. The initial CT finding with small artery and capillary air mimicking infarcts developed into large areas of reversible edema with swelling, and finally limited cortical infarcts with laminar necrosis and gliosis in the white matter.\nDespite initial poor neurological presentation, the patient underwent a remarkably good recovery with a favorable outcome. ICP improved after 9 days; and pentothal infusion was stopped on day 11; neurology improved slowly; and on day 13, he was responsive and obeyed commands but with left hemiplegia. He was extubated on day 15 and then continuously improved until discharge from neurorehabilitation 3 months after the insult. The third and final MRI was performed after 3 weeks, when the patient was fully awake with a GCS score of 14. The finding was resolution of swelling and regression of edema (Figure ). At discharge, he displayed only mild disability, slight neglect, and slight fine motor disability in the left hand. Eight months after the incident, he was back to work with minimal left spatial disability.

Polymyositis as a manifestation of chronic graft-versus-host disease after allo-HSCT
|
A 48-year-old woman was diagnosed with acute myeloid leukemia (AML) in 2013,who fortunately achieved a complete remission of bone marrow after two courses of chemotherapy (IA regimen: idarubicin hydrochloride + cytarabine). Allogeneic HSCT deriving from her HLA-identical brother was performed in February 2014 after a reduced intensity conditioning regimen (Ara-c/Bu/Cy/Me-CCNU). Graft-versus-host disease prophylaxis included cyclosporine(50 mg BID, and then gradually reduced the dose to 25 mg BID)and dexamethasone (5 mg QD). Ten months later, she began to complain limb weakness and mild dyspnea after walking. No myalgia, skin rash, or obvious dysphagia was documented. She stopped taking cyclosporine in May 2015. The muscle weakness and dyspnea were significantly aggravated after a fever in July 2015. The proximal muscles [Medical Research Council (MRC)graded 3] were more severely affected than the distal ones(MRC graded 4). Obvious muscle atrophy was evident on the proximal muscles. Deep tendon reflexes were slightly decreased. The somatic sensations were normal.\nBlood analyses disclosed that the levels of creatine kinase (CK), lactate dehydrogenase (LDH),aspartate aminotransferase (AST), alanine aminotransferase (ALT), and myoglobin were elevated. C-reactive protein (CRP), blood routines, and thyroid glands were in normal ranges and the antinuclear antibodies, and myositis-specific autoantibodies were not detected (Table ). Electromyography (EMG) displayed the myopathic changes. Magnetic resonance imaging (MRI) showed areas of abnormally high signal intensity in the muscles of the left arm on fat-suppressed T2-weighed image, especially the biceps, deltoids, triceps, and subscapular muscles (Figure A,B), suggesting muscle inflammation and edema.\nPathological study of the biopsy specimens from the left biceps demonstrated prominent inflammatory cell infiltration with degenerated and necrotic myofibers. Immunohistochemical staining of the sections revealed that the infiltrating lymphocytes were predominantly T cells (mainly CD8+ T cells with a few CD4+ cells), while B lymphocytes were scarce (no CD20+ cells). Major histocompatibility complex class I (MHC-1) was upregulated in some myofibers. In addition, the membrane attack complex (MAC) was deposited in the necrotic myofibers (Figure ).\nBased on the clinical presentation and the pathologic findings on the biopsied muscle, the polymyositis after allo-HSCT was considered. The patient was initially treated with an increased dosages of prednisone and cyclosporin A (CsA), but no significant improvement was achieved. Thus, rituximab (100 mg) plus a low dose of intravenous immunoglobulin (IVIG, 5-10 g) weekly was applied for consecutive 6 weeks, the patient finally achieved a remarkable improvement of her symptoms with a normal CK level. Until now, the patient has been followed up for one and a half years, and she remained symptom-free on oral prednisone and CsA.

Polymyositis as a manifestation of chronic graft-versus-host disease after allo-HSCT
|
A 31-year-old woman was diagnosed with AML 20 months ago. A first complete remission of AML was achieved with two courses of chemotherapy (DA regimen: pirarubicin + cytarabine; cytarabine + methylprednisolone). Fifteen months ago, she received allo-HSCT after a reduced intensity conditioning regimen with IDA/Bu/Fu/Me-CCNU. The postoperative regimen was consisted of cyclosporine (25 mg BID) and methylprednisolone (40 mg QD and then gradually reduced the dose to 20 mg QD) for GVHD prophylaxis. She was hospitalized because she had limb weakness and myalgia for 5 months. Five months ago, she felt myalgia in both the lower limbs (MRC graded 4) and later the upper limbs (MRC graded 4-). The muscles on the four extremities were generally tender and slight atrophic. Deep tendon reflexes were slightly decreased. The sensation was normal.\nLaboratory tests showed the normal ranges of CK and myoglobin levels. The myositis-specific autoantibodies were not positively detected. The antinuclear antibody (ANA) titer was weakly positive at 1:320 (Table ). MRI showed high intensities in fat-suppressed T2-weighed image in the supraspinatus, scapular muscles, arm muscle group, as well as the leg muscle group and fascia (Figure ,C,D). EMG detected myopathic changes. Muscle biopsy of the quadriceps femoris revealed that the degeneration and necrosis of myofibers were evident, with a large number of inflammatory cell infiltrates in the endomysium, similar to those described in the biopsied muscle from the case one.\nThe therapy was shifted from the previous regimen consisting of oral prednisone and CsA to tacrolimus (3 mg QD) combined with oral methylprednisolone (40 mg QD). The symptoms began to relieve in 2 weeks and had disappeared at about 3 months after the new regimen applied. She had been followed up for over 1 year and was in a good condition on the daily dosage of tacrolimus at 3 mg with methylprednisolone at 12 mg.

A case of non-alcoholic steatohepatitis complicated with severe acute pancreatitis induced by decreased lipoprotein lipase and hepatic triglyceride lipase activity levels in a young Japanese woman
|
A 22-year-old woman was admitted to our hospital with a two-day history of intermittent epigastric pain and nausea without any evidence of trauma. Her past medical history showed an episode of hypertriglyceridemia 2 years before admission. One of her cousins had a history of acute pancreatitis, but the details were unclear. She reported that she did not consume alcohol. She had not been taking any drugs, dietary supplements, or herbal medicines. She had a normal constitution (height, 159 cm; weight, 58.8 kg; BMI, 23.26). On examination, she had severe epigastric pain with symptoms of mild tetany. Her blood pressure was 116/80 mm Hg, her heart rate was 72 beats/min, and her body temperature was 36.5°C. Her blood test results (Table ) were as follows: amylase (AMY), 230 U/L; aspartate aminotransferase (AST), 36 U/L; alanine aminotransferase (ALT), 46 U/L; total cholesterol (T-Cho), 1225 mg/dL; triglyceride (TG), 8595 mg/dL, low-density lipoprotein cholesterol (LDL-C), 58.5 mg/dL; high-density lipoprotein cholesterol (HDL-C), 19.5 mg/dL; and serum calcium (Ca), 7.39 mg/dL. Abdominal enhanced CT revealed swelling of the pancreas with surrounding fat stranding and fluid accumulation that resulted in the thickening of the left renal fascia (Figure A). Furthermore, plain abdominal CT revealed diffuse and large low-density areas in the liver, suggestive of moderate to severe fatty liver (Figure B). No stones, tumors, or congenital anomalies were found in the bile duct or pancreatic duct by magnetic resonance cholangiopancreatography. Based on these findings, she was diagnosed with severe acute pancreatitis and treatment was initiated with gabexate mesilate (2000 mg/d) and meropenem (1000 mg/d) under fasting conditions. On day 15, her CRP levels and serum amylase levels normalized and she was observed to have recovered from pancreatitis; thus, the oral intake was started under calorie and fat restriction. The patient had an uneventful clinical course and was discharged on day 24. The day before discharge, her LPL and HTGL levels were examined using postheparin plasma (Table ). Her LPL activity was lower than the minimal level of the normal range, whereas her LPL mass was almost at the minimal level of the normal range. Similarly, although the HTGL mass was not measured in this study, her HTGL activity was lower than the minimal level of the normal range. After receiving informed consent from the patient and her parents, we performed a genetic analysis to search for an LPL gene mutation. The DNA fragments encoding each of the nine exons of the LPL gene were amplified by a polymerase chain reaction (PCR) and sequenced as previously described., The patient had no specific mutations in exons 1-9 of the LPL gene. After discharge, bezafibrate (400 mg/d) was started to treat hypertriglyceridemia, and her TG level gradually declined. However, her transaminase level did not normalize. Liver biopsy on day 1008 after the 1st admission showed moderate fibrosis (Figure A), and hepatic steatosis and inflammation with hepatocyte ballooning, consistent with a diagnosis of NASH (Non-alcoholic fatty liver disease activity score, 3; Matteoni classification, type 4; Brunt classification, Grade 1/Stage 2) (Figure B). At that point, her serum Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA+-M2BP) level was 2.33 COI (normal; 0-0.99). Finally, the patient was treated with fenofibrate (160 mg/d) and omega-3 fatty acid (2000 mg/d). At the time of this report, she is doing well with normal TG and transaminase levels.

Uterocutaneous fistula due to held placenta in a low resource setting
|
This 32-year-old woman presented to Mutoyi Hospital (Burundi) outpatient clinic complaining of persistent abdominal pain and purulent PV discharge. She had undergone a cesarean section in another hospital 3 months before. To that date, the Pfannenstiel incision had been allegedly resutured twice. Unfortunately, as often in these settings, no medical records of the previous admissions were available.\nShe presented to our attention afebrile and tachycardic (95), otherwise stable with no rigor. Clinical examination revealed a soft abdomen, tender to palpation in the mesogastric region but without signs of peritonism, and with a 4 × 3 cm open wound in the suprapubic area (Fig. ).\nThe blood tests available showed an increased WCC of 14 and Hb of 9 mg/dL, to consider normal in these settings.\nThe US scan revealed no intra-abdominal fluid, but some thick tissue (possible a solid viscous) underneath the wound.\nOn the first day after admission, she delivered from that same wound what we understood could only be a held infected placenta, measuring >15 × 10 × 2 cm (Fig. ).\nAs we realized the uterus was communicating directly and largely with the outside, we opted to perform an emergency laparotomy.\nThe decision was taken to treat the uterocutaneous fistula with a hysterectomy, as the chronically inflamed uterine tissue was unsuitable for repair without tension and would have exposed the patient to a high risk of ruptured uterus in the future.\nThe patient subsequently underwent a successful emergency hysterectomy and was discharged 10 days later in the absence of complications.
