Which is true about murmur of VSD?

A. A systolic crescendo-decrescendo murmur heard best at the upper right sternal border with radiation to the carotids; the murmur is augmented with transient exercise
B. A systolic murmur at the pulmonic area and a diastolic rumble along the left sternal border

Parameter adds predictive information regarding CVS risk stratification | AIIMS Entrance MCQ

Which parameter adds predictive information regarding CVS risk stratification & measurement of serum cholesterol?
A. Anti-chlamydia pneumoniae antibodies 
B. CRP 
C. Homocysteine
D. Plasminogen activator inhibitor 1

Ans. B. C-reactive protein

Recent studies have demonstrated that markers of inflammation correlate with coronary risk and that inflammation plays a role in atheromatous plaque instability. 

Elevations of C-reactive protein, CRP identify patients at increased risk of myocardial infarction MI and poor outcome of acute coronary syndromes. Measurement of CRP adds information regarding risk stratification to standard risk factor such as hypertension, diabetes, smoking, and lipids.

Elevations in homocysteine, lipoprotein A, and plasminogen activator factor I have all been associated with an increased risk at cardiovascular events; however, at thi~ time none have been shown to be useful in populations to improve risk stratification.

Recent studies have suggested that infection with agents such as pneumoniae and cytomegalovirus may playa role in the development of atherosclerosis.

To date no studies have demonstrated a conclusive association, and early studies looking at the utility of antibiotic treatment in coronary artery disease have shown no benefit.

Commonest cause of failure of arthrography | AIIMS Entrance MCQ

Commonest cause of failure of arthrography is:
A. Extra-articular injection of contrast
В. Bubbling of air in the joint
С. False positive interpretation
D. Allergic reaction.

Allergic reaction to contrast medium is rare but when it happens examination will have to be discontinued. Other factors also make this procedure futile

Characters of tricuspid regurgitation | AIIMS MCQs for PG Entrance

Which of the following statements best characterizes tricuspid regurgitation? 
A. Infective endocarditis is a common cause
B. The murmur heard in tricuspid regurgita¬tion decreases with inspiration
C. Large a waves in the jugular venous pulse are characteristic
D. Correction of coexistent left ventricular failure rarely improves the condition

Ans. A. Infective endocarditis is a common cause

Infective endocarditis is a common cause of tricuspid regurgitation. The murmur of tri­cuspid regurgitation typically increases with inspiration. Large v waves are seen in the jug­ular venous pulse. Because a common cause of right ventricular failure and secondary tri­cuspid regurgitation is left ventricular failure, correction of left ventricular failure, when present, often is useful in the treatment of tri­cuspid regurgitation. Diagnosis of tricuspid re­gurgitation usually is made on the basis of clinical or echocardiographic evidence. Car­diac catheterization rarely is used to make the diagnosis

Left ventricular failure Symptoms | Medical PG Preparations

Which of the following physical signs and symptoms is best indicative of left ventricular failure?
A. Neck vein distention 
B. Ascites
C. Anorexia 
D. Orthopnea

Ans. D. Orthopnea

Orthopnea is in­dicative of left ventricular failure. Orthopnea is defined as dyspnea i.e., the feeling of breathlessness that occurs in the recumbent position. Recumbency leads to increased car­diac venous return and, thus, increased left and right ventricular volumes. The increased left ventricular volume results in increased left ventricular filling pressure, which leads to pul­monary congestion and the feeling of breath­lessness. Neck vein distention, ascites, anorexia, and cardiac edema all are signs and symptoms of right ventricular failure.

Function of the thalamus | Medical PG Preparations

Function of the thalamus is: 
A. Arousal

Mutation in k-ras gene and pio4 

• Alcohol abuse or cholelithiasis are not risk factors nor is it associated with coffee consumption.

C. Smoked fish 
D. High fat intake 
E. Japanese are common to develop Ca colon

Ans. B. Low fiber ; (C) Smoked fish; (D) High fat intake ; (E) Japanese are common to develop Ca colon :

Dietary risk factors for colorectal Ca, 

— Diet rich in fat and red meat -                           — low fiber diet. 

• Colorectal Ca has increased in Japan since that ration has adopted a more western diet. 

• Animal Fats : Ingestion of animal fats — increased proportion of anaerobes in the gut microflora which leads to conversion of normal bile acids to carcinogens. This provocative hypothesis is supported by several reports of increased amounts of fecal anaerobes in the stools of pts of colonic Ca. 

• Some studies suggest that certain elements of the diet protect against the development of neoplasia. 

Selenium, dithiothiones, thioester’s, terpenes and carotenoids might act as anticarcinogensby reducing free oxygen radicals in the colon at the muscosal surface, 

• Fiber:-An increase in dietary fiber may lower the incidence of Ca in pts who have a high fat diet. 

Dietary fiber —increases the intestinal transit time — Reduction of the exposure of colonic mucosa to potential carcinogen and dilution of these carcinogens because of enhanced fecal bulk. 

• The role of fiber in colorectal Ca is controversial. Because, a diet low in fiber can lead to chronic constipation and diverticulosis. If a low-fiber diet were a significant risk factor in colorectal Ca, individuals with diverticulosis should be at higher risk for developing colorectal Ca ; This is not the case. 

• According to the National Research Council, interim guidelines for diet recommendation for prevention of colorectal Ca are 

—Fat in the diet from 40-30% of total caories, 

— increased consumption of fiber containing foods. 

—* Limit salt-cured, smoked foods. 

—* Limit food additives show to be potential carcinogens, 

 — Establish research protocals for direction of mutagen in foods. 

— Limit alcohol consumption. 

Clinical Case MCQ of Dysphagia of 6 wks Thiration | PGI MCQs for MD MS Preparations

A 60 yrs old pt presenting with dysphagia of 6 wks thiration with solid foods now can swallow only liquids. Investigations done to diagnose her are-A. CxR. 
B. Ba Swallow. 
C. Endoscopy 
D. USG 
E. CT Scan.

Ans A.  CXR ; (B) Ba- swallow (C) Endoscopy (D) USG ; (E) CT-Scan. 

Progressive dysphagia and weight loss of short duration are initial symptoms in vast majority

of the cases of esophageal carcinoma. Dysphagia initialy for solid foods and gradually progressive to semisolids and liquids suggestive of Ca esophagus. Esophagoscopy is the preferred investigation as it can visualise the tumour and biopsy can be  done for definite diagnosis. 

• Ba-swallow is helpful for diagnosis ;irregular filling defects are seen in oesophagus. 

• Chest CT scan — to detect extent of the tumour to mediastinum and para aortic lymph nodes. 

• A 60 yrs old patient with H/o dysphagia initially to solids & gradually to liquids is a case of Ca esophagus.
