Which of the following vitamin reduces the risk of insulin resistance, obesity, and the metabolic syndrome?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin B12 [<SEP>] The right answer is: C. Vitamin D
Explanation: Higher Intakes of Vitamin D May Be Beneficial There is evidence that Vitamin D intake considerably higher than that required to maintain calcium homeostasis reduce the risk of insulin resistance, obesity, and the metabolic syndrome, as well as various cancers. There is growing evidence that higher vitamin D status is protective against various cancers, including prostate and colorectal cancer, and also against prediabetes and the metabolic syndrome. Desirable levels of intake may be considerably higher than current reference intakes, and ceainly could not be met from unfoified foods. While increased sunlight exposure would meet the need, it carries the risk of developing skin cancer. Reference: Harper; 30th edition; Page no: 552, 553 |

Congenital hydrocele is best treated by
A. Eversion of sac
B. Excision of sac
C. Lord's procedure
D. Herniotomy [<SEP>] The right answer is: D. Herniotomy
Explanation: Congenital hydrocele is best treated with herniotomy if they do not resolve spontaneously. Established acquired hydrocele often have thick walls. They are treated by subtotal excision of the sac. If the sac is small, thin walled and contains clear fluid, Lord's operation is done. Jaboulay's operation where the sac is eveed with placement of testis in a pouch created by dissection in the fascial planes of the scrotum, is an alternative.

Rate limiting step in cholesterol synthesis is catalysed by which of the following enzyme?
A. HMG CoA synthetase
B. HMG CoA reductase
C. Thiokinase
D. Mevalonate kinase [<SEP>] The right answer is: B. HMG CoA reductase
Explanation: Conversion of HMG CoA to mevalonate by HMG CoA reductase is the rate limiting step in the synthesis of cholesterol. Cholesterol is an allosteric inhibitor of HMG CoA reductase Statin drugs acts as competitive inhibitors with mevalonate for binding to HMG CoA reductase. Insulin ors the active form of HMG CoA reductase and increases cholesterol synthesis. Glucagon ours the inactive form and decreases cholesterol synthesis. Ref: Biochemistry By John W.

Flipped LDH indicating Myocardial Infarction is represented by:
A. LDH-1> LDH-2
B. LDH-2 > LDH-1
C. LDH-4 > LDH-5
D. LDH-5 > LDH-4 [<SEP>] The right answer is: A. LDH-1> LDH-2
Explanation: When LDH-1 is greater than LDH-2, it is referred to as flipped LDH and is indicative of MI. LDH-1 isoenzyme is found primarily in hea muscle and is lesser in concentration than the LDH-2 Isoenzyme which is primarily found in RBC. When the concentration of LDH-1 is observed to be greater than LDH2. It is referred to as flipped LDH and is indicative of Myocardial infarction. LDH has five isoenzymes: LDH-1 LDH-1 is found primarily in hea muscle 17% to 27% LDH-2 LDH-2 is primarily found in Red blood cells 27% to 37% LDH-3 LDH-3 is highest in the lung 18% to 25% LDH-4 LDH-4 is highest in the kidney, placenta, and pancreas 3% to 8% LDH-5 LDH-5 is highest in the liver and skeletal muscle 0% to 5% The LDH test helps determine the location of tissue damage. Thus in Normal ratios LDH-1 is less than LDH-2 and LDH-5 is less than LDH-4. When LDH-1 is greater than LDH-2: It is referred to as flipped LDH. It is indicative of MI. When your LDH-5 is greater than your LDH-4: It could mean damage to the liver or liver disease. This includes cirrhosis and hepatitis. Ref: Harrisons 19th edition |

Burst supression pattern on EEG is typically seen in:
A. Anoxic encephalopathy
B. Absence seizures
C. SSPE
D. Herpes simplex encephalitis [<SEP>] The right answer is: A. Anoxic encephalopathy
Explanation: Ref: Ref: Harrisons 18/e p e-45 chapter
As the depth of coma increases, the EEG becomes nonreactive and may show a burst-suppression pattern, with bursts of mixed-frequency activity separated by intervals of relative cerebral inactivity. In other instances there is a reduction in amplitude of the EEG until eventually activity cannot be detected. Such electrocerebral silence does not necessarily reflect irreversible brain damage, because it may occur in hypothermic patients or with drug overdose.
The prognosis of electrocerebral silence, when recorded using an adequate technique, depends upon the clinical context in which it is found. In patients with severe cerebral anoxia, for example, electrocerebral silence in a technically satisfactory record implies that useful cognitive recovery will not occur. |

Test used for factor VIII deficiency identification is-
A. PT
B. APTT
C. D dimer
D. FDP [<SEP>] The right answer is: B. APTT
Explanation: Ans. is 'b' i.e., APTT o Factor VIII is a part of the intrinsic pathway of coagulation. The test used to identity1 the defects in the intrinsic and common pathways of coagulation is PTT. Thus prolonged PTT is a feature of patient with factor VIII deficiency.o Patients with hemophilia have deficiency of factor VIII that results in prolonged PTT.o Tests used to evaluate different aspects of hemostasis.Bleeding timeo It is not a test for coagulation rathers it tests the ability of the vessels to vasoconstrict and the platelets to form a hemostatic plug.o It is the time taken for a standardized skin puncture to stop bleeding,o Normal reference value is between 2-9 minutes.o Prolongation generally indicates the defect in platelet number or function.Prothrombin time (PT)o This assay tests the extrinsic and common coagulation pathway.o So, a Prolonged PT can result from deficiency of factor V, VII. X, prothrombin or fibrinogen.Partial thromboplastin time (PTT)o This assay tests the intrinsic and common coagulation pathways.o So, a prolonged PTT. can results from the deficiency of factor V, VHI, IX, X, XI, XII, prothrombin or fibrinogen.Thrombin timeo It is the time taken for clotting to occur when thrombin is added to the plasma,o It tests the conversion of fibrinogen to fibrin and depends on adequate fibrinogen level,o Prolonged thrombin time results from decreased level of fibrinogen.Defective coagulation pathwayPTAPTTExtrinsicIntrinsicCommonIncreasedNormalIncreasedNormalIncreasedIncreased |

Which of the following is the most specific and sensitive screening test for renovascular hypeension?
A. HRCT
B. CT Angiography
C. Captopril enhanced radionucleotide scan
D. Doppler ultrasound of renal aeries [<SEP>] The right answer is: B. CT Angiography
Explanation: Hypeension due to an occlusive lesion of a renal aery is renovascular hypeensionIn the initial stages, the mechanism of hypeension generally is related to activation of the renin-angiotensin system. Obstruction of the renal aery leads to decreased renal perfusion pressure, thereby stimulating renin secretion. Over time, possibly as a consequence of secondary renal damage, this form of hypeension may become less renin-dependent.As a screening test, renal blood flow may be evaluated with a radionuclide -ohoiodohippurate (OIH) scan, or glomerular filtration rate may be evaluated with a - diethylenetriamine pentaacetic acid (DTPA) scan before and after a single dose of captopril (or another ACE inhibitor).Contrast aeriography remains the "gold standard" for evaluation and identification of renal aery lesions.Harrison 19e pg: 1618 |

C. Aoic stenosis
D. Aoic regurgitation [<SEP>] The right answer is: C. Aoic stenosis
Explanation: Even severe AS may exist for many years without producing any symptoms because of the ability of the hyperophied LV to generate the elevated intraventricular pressures required to maintain a normal stroke volume. Most patients with pure or predominant AS have gradually increasing obstruction over years, but do not become symptomatic until the sixth to eighth decades. Exeional dyspnea, angina pectoris, and syncope are the three cardinal symptoms. Dyspnea results primarily from elevation of the pulmonary capillary pressure caused by elevations of LV diastolic pressures secondary to reduced left ventricular compliance and impaired relaxation. Angina pectoris usually develops somewhat later and reflects an imbalance between the augmented myocardial oxygen requirements and reduced oxygen availability. Exeional syncope may result from a decline in aerial pressure caused by vasodilation in the exercising muscles and inadequate vasoconstriction in nonexercising muscles in the face of a fixed CO, or from a sudden fall in CO produced by an arrhythmia.

A patient with cushinoid features presents with hemoptysis; he shows no response to dexamethasone suppression test; most likely diagnosis here is:
A. Adrenal hyperplasia
B. Adrenal adenoma
C. Ca lung with ectopic ACTH production
D. Pituitary microadenoma [<SEP>] The right answer is: C. Ca lung with ectopic ACTH production
Explanation: Answer is C (Ca lung with ectopic ACTH production); Lack of suppression to dexamethasone challenge (ACTH producing tumor) and presence of hemoptysis (Carcinoma lung) in a patient with Cushinoid features suggests a diagnosis of Carcinoma lung with ectopic ACTH secretion. As a method of diagnostic workup of any patient with suspected Cushings we screen the patient with plasma coisol levels at 8:00 a.m. in the morning. Those with increased coisol levels are subjected to a dexamethasone supression test. In the given question there is lack of suppression to dexamethasone challenge so option (d) is out. Out of the choices remaining the presence of hemoptysis points towards the diagnosis of carcinoma lung with ectopic ACTH. |

Mediastinal lymph node calcification is seen in which one of the following-
A. Metastatic neoplasm
B. Lymphoma
C. Sarcoidosis
D. Bronchiectasis [<SEP>] The right answer is: C. Sarcoidosis
Explanation: Ref:Robbins Basic Pathology (9th Edition),page no.478,479 Sarcoidosis Although sarcoidosis is considered here as an example of a restrictive lung disease, it is impoant to note that sarcoidosis is a multisystem disease of unknown etiology characterized by noncaseating granulomas in many tissues and organs. MORPHOLOGY The diagnostic histopathologic feature of sarcoidosis is the noncaseating epithelioid granuloma, irrespective of the organ involved. This is a discrete, compact collection of epithelioid cells rimmed by an outer zone of largely CD4+ T cells. The epithelioid cells are derived from macrophages and are characterized by abundant eosinophilic cytoplasm and vesicular nuclei. It is not uncommon to see intermixed multinucleate giant cells formed by fusion of macrophages. A thin layer of laminated fibroblasts is present peripheral to the granuloma; over time, these proliferate and lay down collagen that replaces the entire granuloma with a hyalinized scar. Two other microscopic features are sometimes seen in the granulomas: (1) Schaumann bodies, laminated concretions composed of calcium and proteins; and (2) asteroid bodies, stellate inclusions enclosed within giant cells. Their presence is not required for diagnosis of sarcoidosis--they also may occur in granulomas of other origins. Rarely, foci of central necrosis may be present in sarcoid granulomas, suggesting an infectious process. Caseation necrosis typical of tuberculosis is absent The lungs are involved at some stage of the disease in 90% of patients. The granulomas predominantly involve the interstitium rather than air spaces, with some tendency to localize in the connective tissue around bronchioles and pulmonary venules and in the pleura ("lymphangitic" distribution). The bronchoalveolar lavage fluid contains abundant CD4+ T cells. In 5% to 15% of patients, the granulomas eventually are replaced by diffuse interstitial fibrosis, resulting in a so-called honeycomb lung. Intrathoracic hilar and paratracheal lymph nodes are enlarged and calcification in 75% to 90% of patients, while a third present with peripheral lymphadenopathy. The nodes are characteristically painless and have a firm, rubbery texture. Unlike in tuberculosis, lymph nodes in sarcoidosis are "nonmatted" (nonadherent) and do not ulcerate. |

Which test is not useful in a patient with history of Syncopal attack?
A. Electrophysiological testing
B. Tilt Table testing
C. PET Scan
D. Holter monitoring [<SEP>] The right answer is: C. PET Scan
Explanation: Answer is C (PET Scan) : PET scan has- not been mentioned as a test to investigate syncope in Harrisons text. It is the single best answer of exclusion. Electrophysiological tests and 24 hour ECG Holter monitoring are indicated in patients where history suggests a cardiac disease. Upright tilt table testing is indicated for suspected neurogenic / vasodepressor syncope in patients with normal history / examination. Invasive Cardiac Electrophysiologic testing : provides diagnostic and prognostic information regarding Sinus Node function, AV conduction and Supraventricular and Ventricular arrhythmia. Holter monitor : provides 24 - 48 hours monitoring of ECG rhythm on an outpatient basis and is indicated for detection of conduction abnormalities. Upright tilt table testing : Is a test for vasodepressor / neurogenic syncope in patients with normal history / examination. In susceptible patients upright tilt at an angle between 60deg to 80deg for 30 to 60 minutes induces a vasovagal episode. Indications for Table Tilt test include : Recurrent syncope - Single syncope episode that caused injury - Single syncope event in high risk setting (pilot, commercial vehicle driver) Syncope The choice of diagnostic test should be guided by the history and physical examination For All patients Serum electrolytes Glucose Haematocrit |

In a 24 year old man weight of the upper limb is transmitted to the axial skeleton by:
A. Coracoacromial ligament
B. Coracoclavicular ligament
C. Costoclavicular ligament
D. Coracohumeral ligament [<SEP>] The right answer is: B. Coracoclavicular ligament
Explanation: The axial skeleton shapes the longitudinal axis of the human body.

D. Right an dleft coronary artery [<SEP>] The right answer is: A. Pulmonary orifice and atrioventricular orifice
Explanation: Ans. is 'a' i.e., Pulmonary orifice and atrioventricular orifice Interior of right ventricle* It is anteroinferior chamber and projects to the left of right atrium. It is in contact with the sternum.* It is divided into -i) Rough inflowing part (ventricle proper)# It is developed from right half of primitive ventricle.# Its interior is rough due to the presence of muscular ridges known as trabeculae carneae, which are more prominent in apical region.# Trabeculae carneae are of 3 types: -1. Ridges - Linear elevations.Supraventricular crest - a ridge present between the pulmonary and atrioventricular orifices, extends downwards in the posterior wall of the infundibulum.2. Bridges -'Muscular elevations with fixed ends on ventricular walls, the center being free.Septomarginal trabecula: It is a specialized bridge which extends from the right of ventricularseptum to the base of anterior papillary muscle. It contains the right branch of atrioventricular bundle.3. Papillary muscles are conical projections of muscle fiber bundles. Their base is attached to the ventricular wall and the apex is attached to the chordae tendinae, which are further attached to the cusps of atrioventricular (AV) valves. There are three papillary muscles in the right and two in the left ventricle. They regulate closure of atrioventricular valves.ii) Smooth outflowing part (infundibulum or conus arteriosus)# Smooth outflowing part develops from mid portion of bulbus cordis and surrounds pulmonary valveSupraventricular crest (crista supraventriculars) or infundibuloventricular crest separates tricuspid (AV) orifice and pulmonary orifice, i.e. inlet and outlet parts. |

Which of the following statements about Total Infra–Venous Anaesthesia (TIVA) is true –
A. Causes More Renal Toxicity
B. Reduces Cerebral Metabolic Rate
C. Risk of Malignant Hyperthermia is high
D. Inhibits Hypoxic Pulmonary Vasconstriction [<SEP>] The right answer is: B. Reduces Cerebral Metabolic Rate
Explanation: Total intravenous anaesthesia refers to a technique in general anaesthesia using a compination of agents given solely by IV route and in the absence of all inhalation agents.
TIVA (Total intravenous anaesthesia) is produced by IV propoful. Propofol decreases the cerebral metabolic rate.
Propofol does not impair renal function, does not trigger malignant hyperthermia and does not inhibit hypoxic pulmonary vasoconstriction. |

Which of the following iodinated compound is present in a maximum concentration in the thyroid?
A. Monoiodotyrosine (MIT)
B. Diiodotyrosine (DIT)
C. T3
D. Reverse T3 [<SEP>] The right answer is: B. Diiodotyrosine (DIT)
Explanation: THYROID HORMONE SYNTHESIS AND SECRETIONThyroid hormones are synthesized in the colloid, near the apical cell membrane of the follicular cells. Catalyzed by the enzyme thyroidal peroxidase, iodide in the thyroid cell is oxidized to iodine.The iodine enters the colloid and is rapidly bound at the 3 position to tyrosine molecules attached to thyroglobulin, forming monoiodotyrosine (MIT).MIT is next iodinated at the 5 position, forming diiodotyrosine (DIT).Two DIT molecules then condense in an oxidative process ("coupling reaction") to form one thyroxine (T4) molecule.Some T3 is probably formed within the thyroid gland by condensation of MIT with DIT. A small amount of reverse T3 (rT3) is also formed.In the normal thyroid, the average distribution of iodinated compounds is 23% MIT, 33% DIT, 35% T4, 7% T3, and 2% reverse T3. |

H. capsulatum, a dimorphic fungus, is found in soil heavily contaminated with bird droppings. Which of the following statements best describes the presence of the organism in tissue biopsies?
A. Yeasts with broad-based bud
B. Single-cell yeasts with pseudohyphae
C. Arthrospores
D. Oval budding yeasts inside macrophages [<SEP>] The right answer is: D. Oval budding yeasts inside macrophages
Explanation: Histoplasma capsulatum is a dimorphic fungus that forms two types of spores: tuberculate macroconidia and microconidia. Inhalation of the microconidia transmits infection. Inhaled spores (microconidia) are engulfed by macrophages and develop into yeast forms. Most infections remain asymptomatic; small granulomatous foci heal by calcification. However, pneumonia can occur. The heterophile antibody test is useful for early diagnosis of infectious mononucleosis. The figure below illustrates the oval budding yeasts. |

Autosomal recessive polycystic kidney disease features include:
A. Can be diagnosed intrauterine
B. Proceeds to renal failure till children reaches school going age
C. Can be palpated abdominally
D. Hypertension doesn't develop until late stages of the disease [<SEP>] The right answer is: A. Can be diagnosed intrauterine
Explanation: Ans. A. Can be diagnosed intrauterineExplanationClinical features of ARPKD (Autosomal recessive polycystic kidney disease) are:Classic ARPKD is generally diagnosed in utero or within the neonatal period and characterized by greatly enlarged echogenic kidneys in diseased fetuses. (Option a)Reduced fetal urine production may contribute to oligohydramnios and pulmonary hypoplasia.About 30% of affected neonates die shortly after birth due to respiratory insufficiency. Close to 60% of mortality occurs within the first month of life.In the classic group, most patients are bom with renal insufficiency and ESRD (End stage renal disease). (Option b)However, infants often have a transient improvement in their GFR; death from renal insufficiency at this stage is rare.Some patients are diagnosed after the neonatal stage and form the older group. Morbidity and mortality in this group often involve systemic hypertension, progressive renal insufficiency, and liver manifestations.The hallmarks of ARPKD liver disease are biliary dysgenesis due to a primary ductal plate malformation with associated periportal fibrosis, namely congenital hepatic fibrosis (CHF) and dilatation of intrahepatic bile ducts (Caroli's disease). CHF and Caroli's disease can then lead to portal hypertension exhibiting hepatosplenomegaly, variceal bleeding, and cholangitis.Some patients with the diagnosis of ARPKD at 1 year of age with nephromegaly exhibit slowly declining renal function over 20 years with only minimally enlarged kidneys at ESRD (Option c and e) and markedly atrophic kidneys following renal transplantation.The slow progression of renal disease is likely due to increasing fibrosis rather than the development of cysts.Systemic hypertension is common in all ARPKD patients, even those with normal renal function.

You are the medical officer in charge of the immunisation programme at a sub-centre and you are informed by the local ASHA worker that one of the children who was immunised has has been dizzy. On fuher investigation it was confirmed that the symptoms were due to anxiety of pain of the injection and not as a result of the vaccine. You would consider the incidence as:
A. Vaccine reaction
B. Injection reaction
C. Programme error
D. Coincidental [<SEP>] The right answer is: B. Injection reaction
Explanation: The following are the adverse effect following immunisation: Vaccine reaction - Here the event is caused by the inherent propeies of the vaccine when given correctly. Programme error - In this case the event is as a result of error in preparation, handling or administration of the vaccine. Coincidental - The event after immunisation is not caused by the vaccine but by a chance association. Injection reaction - The anxiety of the pain an injection itself may cause hyperventilation, dizziness etc. This is not a result of the vaccine and is called injection reaction.
