| single | Infection with Hepatitis B virus (HBV) at bih or a very young age is associated with chronic HBV infection and the development of hepatocellular carcinoma later in life. In fact, infants born to Hepatitis B surface antigen (HBsAg)-positive mothers are commonly infected, and approximately 90% become chronic carriers of the virus. Chronic carriers suffer from hepatocellular carcinoma at an incidence over 200 times higher than a noncarrier. The current recommendation for infants born of HBsAg-positive mothers is administration of hepatitis B immunoglobulin (HBIg) in the delivery room, with the first dose of the hepatitis B vaccine given at the same time or within 1 week. The second and third dose of the vaccine are then given at 1 and 6 months. With this protocol, 94% protection is achieved. The Epstein-Barr virus is the agent of heterophile-positive infectious mononucleosis. In children, primary EBV infection is often asymptomatic. The measles virus often causes a more severe disease in adults. Over the age of 20, the incidence of complications, including pneumonia, bacterial superinfection of the respiratory tract, bronchospasm and hepatitis, is much higher than in children. Poliovirus causes asymptomatic or inapparent infections 95% of the time. Frank paralysis occurs in approximately 0.1% of all poliovirus infections. However, the probability of paralysis increases with increasing age. | Microbiology | null |

e3c42b9e-ddf9-4268-8123-05cb31e58da8 | Serum marker indicating active viral replication in hepatitis-B is: September 2006, March 2013 | HBsAg | HBeAg | HBcAg | HBV DNA | 1b
| single | Ans. B: HBeAg, D: HBV DNA The first detectable viral marker for hepatitis-B is HBeAg, followed by hepatitis B, e-antigen (HBeAg) and HBV DNA. Titers may be high during the incubation period, but HBV DNA and HBeAg levels begin to fall at the onset of illness and may be undetectable at the time of peak clinical illness. Core-antigen does not appear in blood, but antibody to this antigen (anti-HBc) is detectable with the onset of clinical symptoms. The immunoglobulin M (IgM) fraction is used in an impoant diagnostic assay for acute hepatitis B, infection. Before current molecular assays were available, it was the only marker detectable in the window period, the time between the disappearance of HBsAg and the appearance of anti-HBs. Patients who clear the virus lose HBsAg and develop anti-HBsAb, a long-lasting antibody associated with immunity. The presence of anti-HBsAb and anti-HBcAb (IgG) indicates recovery and immunity in a previously infected individual, whereas a successful vaccination response produces antibody only to HBsAg. HBeAg is another viral marker detectable in blood and correlates with active viral replication and therefore high viral load and infectivity. The-antigen is synthesized from a strand of DNA immediately preceding the area that codes for the core-antigen. | Pathology | null |

| multi | Trisomy 21 or Down syndrome is the most common of the chromosomal disorder.
The most common cause of trisomy and therefore of Down syndrome is meiotic nondisjunction (type II Meiosis error). a Maternal age has a strong influence on the incidence of trisomy 21.
It occurs once in 1550 live births in women under age 20 in contrast to 1 in 25 live births for mothers over age 45. The correlation with maternal age suggests that in most cases the meiotic nondisjunction of chromosome 21 occurs in the ovum.

| multi | Ans. is 'b' i.e., Dexamethasone Coicosteroids should not be used' - Paediatrics for doctors - Frankshann & John Vince Management Protocol The management protocol of babies with asphyxia : Oxygen. In the absence of continuous oxygen saturation monitoring, it is reasonable to give nasopharyngeal oxygen (0.5 litre/min) until the baby recovers. If monitoring is available, oxygen is given as appropriate. Thermal control. Baby's body temperature should be kept in the normal range of 36.5-37.2degC (sometimes the babies become hyperpyrexic). Correction of shock, If peripheral perfusion is poor, it is reasonable to give 20 ml/kg of normal saline initially. If perfusion remains poor, the use of dopamine should be considered. Fluid balance. Give IV fluids at 2/3 maintenance. Use 10% dextrose. Monitor blood glucose with dextrostix and do not let it fall below 2.2 mmol (explains glucose administration) Prevent/control convulsions. In less severely affected babies, phenobarbitone should be given when there is anyuspicion of actual or impending convulsions (phenobarbitone loading dose 20 mg/kg IM or 10mg/kg slowly IV, then 5 mg/kg daily orally). Treat hvpocaleaemia if it occurs (or more practically, if the baby has uncontrollable fitting with anormal dextrostix). (explains calcium gluconate administration) Notes I. Coicosteroids should not be used, and although many paediatricians use mannitol, there is no evidence for its effectiveness. 2. Babies with severe asphyxia may appear to settle relatively quickly after the resuscitation - but there is likely to be a deterioration after 6-12 hours or so as cerebral oedema develops. | Pediatrics | null |

The CBC shows a normal WBC count and increased hematocrit (48 g/dL). Which of the following is the most likely cause of increased hematocrit in this patient? | Acute phase response | Dehydration | Diabetes insipidus | Malabsorption | 1b
| single | Increased hematocrit in this patient reflects hemoconcentration caused by dehydration, secondary to diarrhea. This hematologic condition, termed relative polycythemia, is characterized by decreased plasma volume with a normal red cell mass. When patients suffer from burns, vomiting, excessive sweating, or diarrhea, they not only lose fluid but also suffer electrolyte disturbances. Systemic blood pressure falls with continuous dehydration, and declining perfusion eventually leads to death. Diabetes insipidus (choice C) may cause dehydration but is an unlikely choice because the patient has a history of diarrhea. None of the other choices cause relative polycythemia.Diagnosis: Dehydration, relative polycythemia | Pathology | Hemodynamics |
25fc3284-c2ab-43f5-b16a-e5b35d97aad5 | In XLR diseases, a modified inheritance pattern called 'pseudodominance' occurs when | One parent is affected homozygote and another is unaffected homozygote | One parent is unaffected heterozygote and another is affected homozygote | One parent is normal and another is unaffected het- erozygote | Both parents are unaffected | 1b
| multi | Ans. b (One parent is unaffected heterozygote and another is affected homozygote). (Fig. Harrison 18th/61/l 1)In most instances of AR inheritance, an affected individual is the offspring of heterozygous parents. In this situation, there is a 25% chance that the offspring will have a normal genotype, a 50% probability of a heterozygous state, and a 25% risk of homozygosity for the recessive alleles, in the case of one unaffected heterozygous and one affected homozygous parent, the probability of disease increases to 50% for each child. In this instance, the pedigree analysis mimics an autosomal dominant mode of inheritance (pseudodominance). In contrast to autosomal dominant disorders, new mutations in recessive alleles are rarely manifest because they usually result in an asymptomatic carrier state.PSEUDODOMINANCE# The sudden appearance of a recessive phenotype in a pedigree, due to deletion of a masking dominant gene.# The phenomenon in which a recessive allele shows itself in the phenotype when only one copy of the allele is present, as in hemizygous alleles or in deletion heterozygotes.# An autosomal recessive condition present in individuals in two or more generations of a family, thereby appearing to follow a dominant inheritance patterns.Common explanations include:# A high carrier frequency.# Birth of an affected child to an affected individual and a genetically related (consanguinous) reproductive partner.# In populations with high frequencies of heterozygotes for autosomal recessive conditions, such as in geographically isolated communities, the mating of a homozygote with a heterozygote may result in an inheritance pattern mimicking dominant inheritance (pseudodominance).Examples of diseases with pseudodominance# Storgordt disease (caused by ABCR mutations)# Pseudoxanthoma elasticum (is caused by mutations in the ABCC6 gene, inherited in an autosomal recessive manner and presence of disease in two generations is due to pseudodominance.)# Glycogen storage disease type VII (Tarui's) - it is autosomal recessive, although a few cases with pseudodominance or sumptomatic heterozygous individuals have been found. | Unknown | null |

In normal people, increased osmolality in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma. A low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma. | Physiology | null |

| multi | Ans. is 'a' i.e., Avoid surgery for initial 48-72 hours There are three main measures in the tit of acute intestinal obstruction. These are 1) Gastro intestinal drainage (Nasogastric suction) 2) Fluid and electrolyte replacement 3) Surgery for relief of obstruction The first two steps are always necessary prior to the surgical relief of obstruction. Surgical treatment is necessary for most cases of intestinal obstruction, but it should always be delayed until resuscitation is complete. The timing of surgical intervention is dependent on clinical picture. The classical clinical advice on a case of unrelieved intestinal obstruction is that "Sun should not both rise and set" i.e., the operative procedure should not be delayed beyond 24 hrs. But, there are ceain exceptions to this rule. In some cases operation is delayed in the hope of spontaneous resolution. In adhesive intestinal obstruction, usually occuring after surgery the upto 72 hours in the hope of spontaneous resolution. In these cases continued radiological evidence of obstruction. Also know the four types of obstruction, where operation should be done a) Stangualtion b) Closed loop obstuction c) Colon obstruction d) Early simple mechanical obstruction More about adhesive intestinal obstruction - Commonest cause of intestinal obstruction, usually follows pelvic operations Obstruction due to postoperative adhesions commonly involve the lower small bowel. | Surgery | null |

| single | Linezolid is Oxazolidinone. MOA: It inhibits protein synthesis by preventing formation of the ribosome complex that initiates protein synthesis by binding to 23S ribosomal RNA of the 50S subunit. It is active against Gram positive organisms including Staphylococci, Streptococci, Enterococci, Gram positive Anaerobic cocci and Gram positive bacilli such as Corynebacteria, Nocardia sp. and L.monocytogenes. It is primarily a Bacteriostatic agent but is Bactericidal against Streptococci. It is also active against Mycobacterium Tuberculosis. Thrombocytopenia is the most common complication seen with its chronic use , also Optic and Peripheral Neuropathy and Lactic acidosis can occur (due to inhibition of mitochondrial protein synthesis). Anemia and Neutropenia can also occur . | Pharmacology | Protein Synthesis Inhibitors |
