Drug of choice for absence seizures: March 2011 | Ans. C: Valproate Sodium valproate is effective in absence/petit-mal seizures, combined grand mal and petit mal, myoclonic epilepsy, paial epilepsy, maniac depressive psychosis and as a prophylactic in febrile convulsion Absence seizures/Petit mal seizures (from the French for "little illness", a term dating from the late 18th century). Absences seizures are brief (usually less than 20 seconds), generalized epileptic seizures of sudden onset and termination. They have 2 essential components: - Clinically the impairment of consciousness (absence) - EEG generalized spike-and-slow wave discharges Absence seizures are broadly divided in typical and atypical absence seizures. Typical absence seizures usually occur in the context of idiopathic generalised epilepsies and EEG shows fast >2.5 Hz generalised spike-wave discharges. Atypical absence seizures: - Occur only in the context of mainly severe symptomatic or cryptogenic epilepsies of children with learning difficulties who also suffer from frequent seizures of other types such as atonic, tonic and myoclonic - Onset and termination is not so abrupt and changes in tone are more pronounced - Ictal EEG is of slow less than 2.5 Hz spike and slow wave. - The discharge is heterogeneous, often asymmetrical and may include irregular spike and slow wave complexes, fast and other paroxysmal activity. - Background interictal EEG is usually abnormal. Treatment of patients with absence seizures only is mainly with sodium valproate or ethosuximide, which are of equal efficacy controlling absences in around 75% of patients. Sodium valproate as a single drug is the DOC if tonic clonic seizures are also present or emerge during the therapy with ethosuximide Lamotrigine monotherapy is less effective with nearly half of the patients becoming seizure free. | 3 | Carbamazepine | Lamotrigine | Valproate | Phenytoin | Pharmacology | null | c6cb65bc-f7d8-4e5b-a19e-837f0510b746 | single |

A child is taken to a pediatrician because his mother notices that his eyes appear very puffy. The mother said that the boy's eyes appeared normal two days ago, and pa of what caused her concern was that her child seemed to be rapidly becoming ill. On physical examination, the boy is noted to have generalized edema. No hypeension or jaundice is noted. Blood urea nitrogen and serum creatinine are within normal limits. A urine sample is collected, and the nurse notices that the top of the urine has a small amount of foam at the top. Urinalysis is negative for glucose, red cells, white cells, casts, crystals, and bacteria. A 24-hr-urine specimen is collected, which demonstrates proteinuria of 55 mg/h/m2. Which of the following is the most likely diagnosis? | Proteinuria greater than 40 mg/h/m2 in a child or 3.5 g/d/1.73 m2 in an adult produces nephrotic syndrome, which is characterized by generalized edema, often most noticeable in the face. The condition develops when large amounts of protein are spilled through the glomeruli into the duct system of the kidneys. In contrast, nephritic syndrome is accompanied by lower levels of proteinuria, together with microscopic or macroscopic hematuria (red cells and blood in urine). Acute and chronic renal failure are characterized by rising serum levels of BUN and creatinine. The findings seen do not suggest lower urinary tract disease, which is typically due to a lower urinary tract infection (which would show bacteria and white cells), calculi (crystals would likely be present), or tumor (which would show abnormal bladder epithelial cells). | 4 | Acute renal failure | Chronic renal failure | Lower urinary tract disease | Nephrotic syndrome | Pediatrics | null | 9dbfe50d-9f1b-40f7-9d22-086482e85b07 | multi |

All the following features our ventricular tachycardia as the cause of broad-complex tachycardia, except - | Ventricular tachycardia can be classified based on its morphology: Monomorphic ventricular tachycardia means that the appearance of all the beats match each other in each lead of a surface electrocardiogram (ECG). Scar-related monomorphic ventricular tachycardia is the most common type and a frequent cause of death in patients having survived a hea attack, especially if they have weak hea muscle. RVOT tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract. RVOT morphology refers to the characteristic pattern of this type of tachycardia on an ECG. The source of the re-entry circuit can be identified by evaluating the morphology of the QRS complex in the V1 lead of a surface ECG. If the R wave is dominant (consistent with a right bundle branch block morphology), this indicates the origin of the VT is the left ventricle. Conversely, if the S wave is dominant (consistent with a left bundle branch block morphology, this is consistent with VT originating from the right ventricle or interventricular septum. Polymorphic ventricular tachycardia, on the other hand, has beat-to-beat variations in morphology. This may appear as a cyclical progressive change in cardiac axis, previously referred to by its French name torsades de pointes ("twisting of the spikes"). However, at the current time, the term torsades de pointes is reserved for polymorphic VT occurring in the context of a prolonged resting QT interval. Another way to classify ventricular tachycardias is the duration of the episodes: Three or more beats in a row on an ECG that originate from the ventricle at a rate of more than 120 beats per minute constitute a ventricular tachycardia Ref Harrison 20th edition pg 1423 | 3 | Fusion beats | Extreme left axis detion | Very broad QRS complexes | Response to carotid sinus massage | Medicine | C.V.S | 83d2c3ba-b1ba-4512-a6a4-37de091425e8 | multi |

Radiation induced thyroid cancer is - | Radiation-induced thyroid cancer Authors: Section Editors: Deputy Editor: INTRODUCTION Radiation exposure of the thyroid during childhood is the most clearly defined environmental factor associated with benign and malignant thyroid tumors. The risk of thyroid cancer following irradiation is related to radiation dose and age (greater for children exposed early in life), and the risk persists throughout life. Radiation exposure during childhood also increases the risk of benign thyroid nodules and hypothyroidism. The purpose of this topic is to review the evaluation of a patient with a history of childhood radiation exposure and how such a history affects treatment of patients with thyroid tumors. Radiation injury to other organs is reviewed separately. (See and .) RADIATION EXPOSURE Type of exposure -- Radiation exposure may be external or internal. *External - The predominant types of external radiation are diagnostic radiographs, therapeutic radiation for the treatment of cancer, and historical use of external radiation to treat a wide variety of nonmalignant conditions. External radiation also includes brachytherapy, whereby a sealed radiation source is placed adjacent to a treatment area. *Internal - Internal radiation exposure includes ingestion of foods or liquids contaminated with radioactivity or by inhalation of radioactive gases or paicles. Internal radiation occurs after exposure to nuclear fallout (from testing and accidents at operating nuclear power plants or above ground nuclear explosive testing) or after ingestion of radioiodine for diagnostic tests and for therapy of hypehyroidism. | 1 | Papillary | Follicular | Anaplastic | Medullary | Pathology | Endocrinology | dc66ca91-10dd-4a3b-837e-6604434bd306 | single |

An 8-hour-old term infant develops increased respiratory distress, hypothermia, and hypotension. A complete blood count (CBC) demonstrates a white blood cell (WBC) count of 2500/mL with 80% bands. The chest radiograph is shown below. Which of the following is the most likely diagnosis? | (c) Source: (Hay et al, pp 1163-1166. Kliegman et al, pp 925-928. McMillan et al, pp 482-483, 501-506. Rudolph et al, pp 1097-1099.) The radiograph shows diffuse that infiltrates bilaterally; this can be seen with neonatal pneumonia or primary surfactant deficiency. The rapid onset of the symptoms, the low WBC count with left shift, and the depicted chest x-ray findings, however, are typical of a patient with group B streptococcus (GBS) pneumonia. Appropriate management would include rapid recognition of symptoms, cardiorespiratory support, and prompt institution of antibiotics. Despite these measures, mortality from this infection is not uncommon. The other infectious causes listed do not present so early, and the noninfectious causes listed do not cause elevations in the band count. GBS disease in the infant is decreasing in incidence with better prevention strategies in the perinatal period; early screening in pregnancy and treatment with antibiotics just prior to delivery to eliminate GBS colonization markedly decreases the risk to the infant. Congenital syphilis can cause pneumonia, but it is diagnosed at birth along with other features including hepatosplenomegaly, jaundice, rashes, hemolytic anemia, and others. Diaphragmatic hernia presents with early respiratory distress, but the diagnosis is confirmed clinically with bowel sounds heard in the chest and a radiograph that has loops of bowel located above the normal placement of the diaphragm. Transient tachypnea of the newborn (TTN) causes an increase in respiratory rate and occasionally a low oxygen requirement; the history is often positive for a cesarean delivery, and the radiograph shows retained fluid in the fissures. TTN does not cause temperature instability nor an abnormal CBC. Chlamydial pneumonia is not a condition that occurs in an 8-hour-old infant; it is generally a mild pneumonia that can develop in an exposed infant at several weeks of life. | 3 | Congenital syphilis | Diaphragmatic hernia | Group B streptococcal pneumonia | Transient tachypnea of the newborn | Pediatrics | Growth, Development, and Behavior | bd20d1fa-9e46-42cf-96ad-bc776eec6540 | single |

Bochdalek hernia is related to - | Ans. is 'b' i.e., Pleuroperitoneal canal Bochdalek herniao Most Bochdalek hernia are on the left side (~80%) and may rarely be bilateral.o Compression of the lung results in pulmonary hypoplasia, involving both the lungs (ipsilateral > contralateral)o Pulmonary vasculature is also abnormal leading to pulmonary hypertension.o Thus the two main factors that affect morbidity and mortality are pulmonary hypoplasia and pulmonary hypertension.o The most frequent clinical presentation of CDH is respiratory distress due to severe hypoxemia,o The anteroposterior diameter of the chest may be large along with a scaphoid abdomen,o The diagnosis of CDH can be made prenatally by ultrasound.o The postnatal diagnosis is relatively straightforward because a plain chest radiograph demonstrates the gastric air bubbles or loops of bowel within the chest. There may also be a mediastinal shift away from the side of the hernia.o Historically, the surgical repair of a CDH was considered to be a surgical emergency' because it was believed that the abdominal viscera within the chest prevented the ability to ventilate. More recently with the recognition of the role of pulmnary hypertension and pulmonary hypoplasia and the adverse effects of early operative repair on the pulmonary function has caused a policy of delayed repair.o Thus most pediatric surgeons wait for a variable period (24 to 72 hrs) to allow for stabilization of the infant before doing surgical repair.Congenital diaphragmatic herniao It is the herniation of abdominal contents into the thoracic cavity through the diaphragmatic defecto The defect may be:Posterolateral (Bochdalek hernia)Retrosternal (Morgagni hernia)At the esophageal hiatus (hiatal hernia)Adjacent to the hiatus (paresophageal hernia)o Although all these defects are congenital, the term congenital diaphragmatic hernia is generally used for Bochdalek hernia. | 2 | Inguinal canal | Pleuroperitoneal canal | Femoral canal | Obturator foramen | Surgery | Unusual Hernias | bad555df-d202-4de6-957f-c976fa530600 | single |
A 4 yr old partially immunized boy came to OPD with history of bouts of coughing. On staining the sputum sample an organism with bipolar staining was seen. Which among the following organism it would be? | REF: (B) B. pertussisREF: Jawetz Microbiology, 24th Ed Ch. 19BORDETELLA PERTUSSIS:The organisms are minute gram-negative coccobacilli resembling H influenzae. With toluidine blue stain, bipolar metachromatic granules can be demonstrated. A capsule is present. After an incubation period of about 2 weeks, the "catarrhal stage" develops, with mild coughing and sneezing. During this stage, large numbers of organisms are sprayed in droplets, and the patient is highly infectious but not very ill. During the "paroxysmal" stage, the cough develops its explosive character and the characteristic "whoop" upon inhalation. This leads to rapid exhaustion and may be associated with vomiting, cyanosis, and convulsions. The "whoop" and major complications occur predominantly in infants; paroxysmal coughing predominates in older children and adults. The white blood count is high (16,000-30,000/ uL), with an absolute lymphocytosis. Among provided options, T. pestis and B. pertussis produce bipolar metachromatic appearance, but considering the partial immunization status and age of patient, b. pertussis is answer of choice. | 2 | Y.
