Differential diagnosis for pancytopenia with cellular bone marrow include the following except - | In megaloblastic anemia , RBCs WBCs & platelets decreases (pancytopenia) & the cellularity of the bone marrow increases from moderate to hypercellular.Ceain morphologic features are common to all forms of megaloblastic anemia. The bone marrow is markedly hyper- cellular and contains numerous megaloblastic erythroid pro- genitors. Megaloblasts are larger than normal erythroid progenitors (normoblasts) and have delicate, finely reticu- lated nuclear chromatin (indicative of nuclear immaturity) (Fig. 11-11). As megaloblasts differentiate and acquire hemo- globin, the nucleus retains its finely distributed chromatin and fails to undergo the chromatin clumping typical of normo- blasts. The granulocytic precursors also demonstrate nuclear- cytoplasmic asynchrony, yielding giant metamyelocytes. Megakaryocytes may also be abnormally large and have bizarre multilobed nuclei. In the peripheral blood the earliest change is the appear- ance of hypersegmented neutrophils, which appear before the onset of anemia. Normal neutrophils have three or four nuclear lobes, but in megaloblastic anemias they often have five or more. The red cells typically include large, egg- shaped macro-ovalocytes; the mean cell volume often is greater than 110 fL (normal, 82 to 92 fL). Although macro- cytes appear hyperchromic, in reality the mean cell hemoglo- bin concentration is normal. Large, misshapen platelets also may be seen. Morphologic changes in other systems, espe- cially the gastrointestinal tract, also occur, giving rise to some of the clinical manifestations.

On evaluation, atrophic rhinitis is diagnosed. What can be the etiology in this patient to develop secondary atrophic rhinitis? | Specific infections like syphilis, lupus, leprosy, and rhinoscleroma may cause destruction of the nasal structures leading to atrophic changes. Atrophic rhinitis can also result from long-standing purulent sinusitis, radiotherapy to nose or excessive surgical removal of turbinates. Extreme detion of nasal septum may be accompanied by atrophic rhinitis on the wider side. | 1 | Chronic sinusitis | Nasal trauma | Oropharyngeal cancer | Strong hereditary factors | ENT | null | f7851b1b-d2dd-4722-b134-2cf6a278131a | single |
A 42-year old female presents with the complaint of bleeding gums for the past 20 days. Intra-oral examination shows thickened and friable gums. Also, she has hepatosplenomegaly with generalized non tender lymphadenopathy. The blood count reveals: Hemoglobin 11.4 g/dl, Platelet count 90,000/mm3, WBC count 4600/mm3. The bone marrow biopsy shows 100% cellularity, with many large blasts that are peroxidase negative and nonspecific esterase positive. Which of the following is the most likely diagnosis for this patient? | Patient has an “aleukemic” leukemia in which leukemic blasts fill the marrow, but the peripheral blood count of leukocytes is not high. The staining of the blasts suggests the presence of monoblasts (peroxidase negative and nonspecific esterase positive). So, the likely diagnosis for her is M5 leukemia, which is characterized by increased chances of tissue infiltration and organomegaly.
Other options:
Acute lymphoblastic leukemia is typically seen in children and young adults.
Acute megakaryocytic leukemia is typically accompanied by myelofibrosis and is rare. The blasts react with platelet-specific antibodies.

Meniscal tears usually result from which of the following circumstances? | Most meniscal tears are produced by flexion and rapid rotation. A classic example ("football knee") involves a player who is hit while running. The knee, supporting all the player's weight, usually is slightly flexed, and the foot is anchored to the ground by cleats. Impact from an opposing player usually causes rotation almost entirely restricted to the knee. The injury involves rapid rotation of the flexed femoral condyles about the tibial plateau, which most frequently tears the medial meniscus. (Less frequently, the lateral meniscus is torn.) A tear in the inner free border of the cartilage is also common whenever excessive rotation without flexion or extension occurs. Early surgical removal of the displaced menisci is usually recommended to prevent further damage to the cartilage or ligaments. | 2 | Hyperextension | Flexion and rotation | Simple hyperflexion | Compression | Surgery | Orthopedics | 3106dc30-60fc-41b5-8fa9-5ddcbfab28d8 | multi |

Normal size but non functioning uterus is usually associated with : | A hysterosalpingogram or preferably a diagnostic hysteroscopy helps to establish the diagnosis of Asherman syndrome, first described in 1948. Operative hysteroscopy to lyse the synechiae, followed by cyclic hormonal therapy with high doses of conjugated oestrogens of 2.5-5.0 mg/day for 3-6 months, results in the restoration of menstruation in about 50% cases. Some surgeons prefer to inse an intrauterine device in the uterine cavity after lysis of adhesions to ensure keeping the cavity patent and prevent recurrence of adhesions. Asherman syndrome is caused by dilatation and curettage (D&C), medical termination of pregnancy (MTP), uterine packing in postpaum haemorrhage, uterine infection and tubercular endometritis.

Reversible loss of polarity with abnormality in size and shape of cells is known as - | Metaplasia Metaplasia is an adaptive change in which one adult (mature) cell type is replaced by another adult (mature) cell. In this differentiation is not lost, rather it changes from one lineage to another, i.e. stems cell differentiates along a new pathway. But, the resulting cells are fully mature and differentiated. It is reversible. There is no pleomorphism, and cell polarity as well as cell & nuclear size are not altered. Dysplasia Dysplasia means disordered (abnormal) growth ---> there is disordered differentiation and maturation. This generally consists of an expansion of immature cells, with a corresponding decrease in the number and location of mature cells there is loss of uniformity of individual cells. Dysplastic cells show following feature Loss of polarity Hyperchromatosis Increased nuclear cytoplasmic size ratio (normal 1:4 to 1:6). Pleomorphism Increased number of mitosis with normal pattern. Dysplasia is parially reversible, i.e. It is reversible in early stage and later on it is irreversible. Term Dysplasia is usually used, when these changes occur in epithelium. When dysplastic changes involve the entire thickness of epithelium, it is concidered as preinvasive lesion and is referred to as carcinoma in situ. Anaplasia Anaplasia means lack of differentiation. That means anaplastic cells resemble primitive appearing, unspecialized (undifferentiated) cells. o Anaplasia is seen only in malignancy.

Malignant hyperthermia is caused due to which of the following mechanism? | Ans. is 'c' i.e., Increased intracellular Ca o The mechanism involves a sudden rise in intracellular calcium due to release of stored calcium in sarcoplasmic reticulum, stimulating contraction, rhabdomyolysis and a hypermetabolic state.o Tachycardia and not bradycardia, is a feature of malignant hyperthermia.MALIGN ANT HYPERTHERMIAo Malignant hyperthermia is a life-threatening medical emergency which is genetically determined. The condition occurs during or immediately after anaesthesia and may be precipitated by potent inhalational agents,o The mechanism involves a sudden rise in intracellular calcium due to release of stored calcium in sarcoplasmic reticulum stimulating contraction, rhabdomyolysis and a hypermetabolic state.Drugs causing malignant hyperthermia# Succinylcholine# Desflurane# Tricyclic antidepressants# Halothane# Cyclopropane# Phenothiazines# Isoflurane# Ether# Lignocaine# Enflurane# Methoxyflurane # Sevoflurane# MAO inhibitors o Succinylcholine is the most common cause of MHoAmongst inhalational agents halothane is the most common cause.o Combination of Sch and Halothane has a much higher incidence.Clinical featureso Masseter spasm - if a patient develops severe masseter spasm after suxamethonium, there is a significant possibility of malignant hyperthermia.o Tachycardia, arrhythmias and hypertension.o Hyperthermiao Rise in end-tidal CO2 - May rise to more than 100 mm Hg (normal is 32-42 mm Hg). It is the earliest and most sensitive indicator.o Hyperkalemia, metabolic acidosis, elevated creatininephosphokinase, muscle rigidity,o Increased myoglobin, renal failure.o Muscle biopsy contracture test (definitive diagnostic procedure) :- The muscle biopsy contracture test is the most sensitive and specific test. The Caffeine Halothane Contracture test (CHCT), a test performed on freshly biopsied muscle; is the "gold standard" for diagnosis of malignant hyperthermia. However, the test is available only at few centers in the world (only about 30 centers world wide) and it is very costly. The CHCT test should be considered for all those judged to be at significant risk for malignant hyperthermia, either through family history, or by elicitation of signs of an episode of malignant hyperthermia, or if there had been any previous uncharacterized adverse reaction to a general anesthetic.Managemento Stop all anaesthetics immediately,o Hyperventilation with 100% oxygeno Cooling of body by ice coolingo Correct acidosis and hyperkalemia,o Maintain urine output,o IV dantrolene is the drug of choiceo Procaine is the local anaesthetic of choice for malignant hyperthermia patients,o Propofol is the intravenous anaesthetic of choice for malignant hyperthermia patient | 3 | Increased intracellular Na | Decreased intracellular chlorine | Increased intracellular Ca | Increased serum K | Anaesthesia | Depolarising Neuromuscular Blocking Agents | 36fe2959-43b2-4e8c-8aa6-3c42e2e84ef9 | single |

A 52 year old woman has long standing rheumatoid ahritis (RA) and is being treated with coicosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs). Which of the following cardiac complications may arise in this clinical setting? | Long-standing inflammatory conditions such as rheumatoid ahritis (RA) are associated with deposition of a form of amyloid known as AA (amyloid-associated protein), which may involve kidneys, hea, liver, skeletal muscle, and skin, for example. Amyloid deposition in the myocardium results in decreased compliance and impaired diastolic filling, i.e., restrictive cardiomyopathy. The myocardium has a rigid and waxy texture. This form of amyloid, as well as any other biochemical form, can be visualized on tissue section by staining with Congo red, which acquires a characteristic apple-green birefringence under polarized light. Constrictive pericarditis is due to any pathologic process that results in fibrous thickening of the pericardium, with resultant impaired compliance. Clinically, therefore, this condition manifests with a picture similar to restrictive cardiomyopathy because of impaired diastolic filling. Constrictive pericarditis is usually caused by previous episodes of acute pericarditis, especially hemorrhagic, suppurative, and caseous pericarditis. Dilated cardiomyopathy is characterized by massive ventricular dilatation and may be caused by genetic alterations, myocarditis, toxic insults (alcohol), metabolic disorders (hemochromatosis), etc. Most cases are idiopathic. The main pathophysiologic alteration is impaired contractility. You may be tempted to think that this patient is prone to developing hypersensitivity myocarditis, but this form of myocardial disease has been repoed after treatment with some antihypeensive agents,antibiotics, diuretics and not with coicosteroids or NSAIDs. Fuhermore, myocarditis manifests acutely with arrhythmias and hea failure, and chronically with dilated cardiomyopathy and congestive hea failure. Ref: Hoit B.D. (2011). Chapter 34.

LASIK (Laser assisted in situ keratomileusis) is useful in treatment of | Ans. d (All of the above) (Ref. Khurana's ophthalmology, 2nd ed., p 77; Parson's 20th/pg. 76)EXCIMER LASER IN SITU KERATOMILEUSIS (LASER)# Principle:- Myopia is corrected with preservation of Bowman's layer.- A superficial corneal flap (approx. 160 pm) is created with a microkeratome.- The keratome is withdrawn, the flap is reflected, and the exposed underlying corneal stroma is ablated with an excimer laser to correct the myopia.- Then the flap is repositioned on the corneal bed and fixed in place by force of its own adhesion.# Indication:- Severe myopia (up to 10-12 diopters).- Photoablation:* Excimer laser produces photoablation.* It produces UV light of very short wavelength, which breaks chemical bonds of biologic materials, converting them into small molecules that diffuse away.- Photorefractive keratectomy:* LASIK for correcting refractive errors and* LASIK for phototherapeutic keratectomy for corneal disease like "band-shaped" keratopathy.# LASIK is superior to photorefractive keratectomy in that it:- Less painful procedure* As LASIK does not expose raw corneal surface at the end of surgery it is less painful.- Can be repeated by lifting the flap created if further refinement is necessary- Gives a faster visual rehabilitation- Has less myopic regression- Causes less scarring than photorefractive keratectomy- Can Rx higher myopia* It can also treat a higher myopia, causes less scarring and has less myopic regression. However, because a flap needed to be created, it has a higher potential risk.* Involves the use of microtome* Is contraindicated in patients with thin cornea# Side effects of LASIK:- Reduced corneal sensation- Inaccurate biometry if the patient requires cataract surgery in later life- Tear film abnormality- Erroneously high intraocular pressure with applanation tonometer. | 4 | Myopia | Astigmatism | Hypermetropia | All of the above | Ophthalmology | Errors of Refraction | 55184e4d-a1c6-45d0-b694-a5350d311fe3 | multi |

The tissues most sensitive to atropine are | Atropine is highly selective for muscarinic receptors. Its potency at nicotinic receptors is much lower, and actions at nonmuscarinic receptors are generally undetectable clinically.The effectiveness of antimuscarinic drugs varies with the tissue and with the source of agonist. In most tissues, antimuscarinic agents block exogenously administered cholinoceptor agonists more effectively than endogenously released acetylcholine.Tissues most sensitive to atropine are the salivary, bronchial, and sweat glands.Secretion of acid by the gastric parietal cells is the least sensitive.

Most common cause of scleritis - | Ans. is 'a' i.e., Rheumato.id arthritis Scleritiso Scleritis is an uncommon disorder which is characterized by cellular infiltration, destruction of collagen and vascular remodelling. Scleritis is usually a bilateral disease and occurs most frequently in women. It is associated with connective tissue diseases in 50% of cases. Rheumatoid arthritis is the most common association . Other important causes are PAN, SLE, Ankylosing spondylitis, Wegener's granulomatosis, dermatomyositis, Reiter's syndrome, Non- specific arteritis, Polychondritis and Gout.Clinical features of Scleritiso Patients complain of moderate to severe pain which is deep and boring in character and often wakes thepatient early in the morning. Ocular pain radiates to the jaw and temple. It is associated with localised or diffuse redness, mild to severe photophobia and lacrimation. Occasionally there occurs diminution of vision.Complicationso Complications are common in necrotizing scleritis and include sclerosing keratitis, Keratolysis, Complicated cataract, Uveitis and secondary glaucoma. Rarely, scleritis may also cause retinal detachment and macular edema. These are due to spread of inflammation from sclera into the uveal tract. | 1 | Rheumatoid arthritis | SLE | Sjogren's Syndrome | Behcet's Disease | Ophthalmology | Miscellaneous (Sclera) | 00aa7367-b008-4efc-adc3-395cc46f6537 | single |
