4. A 29-year-old white female is hospitalized following a right middle cerebral artery stroke confirmed on an MRI scan. Her past medical history is remarkable only for a history of an uncomplicated tonsillectomy during childhood, and a second-trimester miscarriage 3 years ago. The only remarkable finding on physical examination is left hemiplegia.
The initial laboratory workup reveals normal hematocrit and hemoglobin levels, a normal prothrombin time, and a platelet count of 200,000/mm3 (N 140,000-440,000). The active partial thromboplastin time is 95 sec (N 23.6-34.6), and it does not normalize when the patient's serum is mixed with normal plasma. A serum VDRL is positive, and a serum FTA-ABS is nonreactive.Which one of the following is the most likely diagnosis?
Thrombotic thrombocytopenic purpura
Protein C deficiency
5.A 43-year-old white female presents with a 4-year history of irregular, intermittent vaginal bleeding. She is not taking hormonal therapy. Her past history is negative.

What is the Diagnosis?
1 polycystic ovarian syndrome
2 carcinoma of the uterine cervix
3 endometrial cancer
*4 uterine leiomyomata
5 ovarian carcinoma
6.Which one of the following is most likely to be a factor in the pathogenesis of gastric ulcer?
1 Excess gastric acid
2 Increased serum gastrin
3 An increased number of parietal cells
*4 Reflux of duodenal contents into the stomach
5 Impaired gastric emptying
While the complete etiology and pathogenesis of gastric ulcer are not known, impairment of the mucosal barrier to the back diffusion of hydrogen ion appears to be involved in the process. The reflux of bile and other duodenal contents into the stomach, which has been found in gastric ulcer patients, is thought to be one mechanism of mucosal barrier disruption. Since most patients with gastric ulcer have normal or low acid production, excessive acid is probably not a factor. Similarly, impaired gastric emptying is not common in such patients, and when it occurs it appears to be a consequence of the condition and not a cause. The number of parietal cells is increased in duodenal ulcer patients but is normal in patients with gastric ulcers. Fasting gastrin levels are variable in the presence of gastric ulcer and appear to correlate inversely with acid secretion. Hypergastrinemia is not a primary factor in gastric ulcer. When it occurs it is a physiologic response to low gastric acidity.Ref: Schwartz SI (ed): Principles of Surgery, ed 7. McGraw-Hill, 1999, p 1194.
7. A 27-year-old white male has a clinical complex of jaundice and chorea. The diagnosis of Wilson's disease is confirmed by which one of the following?
1 Liver biopsy evidence of chronic active hepatitis
2 History of a manic-depressive psychosis
3 Kayser-Fleischer rings of the cornea
*4 Inability to incorporate a copper isotope into ceruloplasmin Wilson's disease is an autosomal recessive abnormality in the hepatic excretion of copper, resulting in toxic accumulations of the metal in the liver, brain, and other organs. The manifestations of this disease may include liver disease leading to cirrhosis, neurologic or psychiatric disturbances, and Kayser-Fleischer rings of the cornea. However, none of these conditions is found only with Wilson's disease. Hepatitis B is also associated with chronic active hepatitis. Many psychiatric illnesses, including schizophrenia and other bizarre behavioral disturbances, are indistinguishable from Wilson's disease, but these conditions are not necessarily associated with copper metabolism. Kayser-Fleischer rings may also be associated with certain cataracts. Classically, the diagnosis is made by the demonstration of a serum concentration of ceruloplasmin less than 20 mg/dL and either (1) Kayser-Fleischer rings, or (2) a liver biopsy sample containing greater than 250 micrograms of copper per gram of dry weight. However, the diagnosis can be confirmed by a test of the patient's inability to incorporate radioactive copper into ceruloplasmin.Ref: Fauci AS , Braunwald E, Isselbacher KJ, et al (eds): Harrison 's Principles of Internal Medicine, ed 14. McGraw-Hill, 1998, pp 2166-2169
8. A 34-year-old white male is brought to the emergency department following an automobile accident in which he was the only occupant of the vehicle. He lost control of the vehicle and hit a utility pole. He was knocked unconscious initially, but he is now awake and combative. You note a strong smell of alcohol. He has a frontal hematoma approximately 3 cm in diameter and an actively bleeding 4-cm laceration of the occiput. He will not permit you to examine him further and he prepares to leave the emergency department.
*1 detain him in the emergency department
2 make him sign out against medical advice
3 tell him that he cannot return if he leaves
4 tell him that if he leaves he can return later
Two of the most important ethical principles are respect for autonomy and beneficence. Respect for autonomy means regarding patients as rightfully self-governing in matters of choice and action. To make an autonomous decision, the patient must be mentally sound, have knowledge and understanding of the facts, and be free of coercion. Beneficence means that physicians are motivated solely by what is good for the patient. There are often ethical conflicts between these two principles. This particular patient is clearly in need of further emergency treatment, but he refuses. He has had a significant head injury, is combative and possibly intoxicated, and therefore cannot be considered mentally sound. The physician should detain him for his own good and provide the appropriate care. Threatening him, having him sign out against medical advice, and encouraging him to return later are not appropriate because his mentation is impaired.Ref: Goldman L, Bennett JC (eds): Cecil Textbook of Medicine, ed 21. WB Saunders Co, 2000, pp 5-6.
9. A 70-year-old white male is found to have microscopic hematuria on routine urinalysis. The most likely cause is

12. An overweight 60 year old white male comes to your office for an early appointment to know about his cholesterol and heart disease risks. He is a diabetic for the past 25 years, smokes 1 packet per day for the past 20 years, has mild hypertension and is on a betablocker for that. His elder brother died at the age of 52 suddenly. His father had a stroke at the age of 72 and died later.You send for his fasting lipid profile. You discuss with him the ways how heart disease risk is calculated.When telling him about his coronary artery disease risks,Which of the following IS NOT A RISK FACTOR for CAD?
c. Brother dying of probable myocardial infarction at 52
*d. Diabetes Mellitus
e.His lipid profile showing a Low HDL level
f. His age
If U have diabetes U are considered just like a person with COronary Heart disease. SO DM does not increase UR risk for coronary heart diseasae BUT IT ITSELF IS CORONARY HEART DISEASE
13. a pregnant pt with preeclampsia. Bp is 160/120. what anti-HTN medication ?
Hydralazine is the DOC for BP control in preeclamptic patients. However, parenteral hydralazine is provided only to pharmacists upon special emergency request. Therefore, the physician must be comfortable using other antihypertensive agents. Labetalol has alpha-adrenergic and beta-adrenergic blocking effects and can be used to provide rapid control of severe hypertension. Other antihypertensive agents have significant adverse effects and should not be used as primary agents. Diazoxide may cause hyperglycemia and inhibit labor, and nitroprusside may cause fetal cyanide toxicity. Diuretics should be avoided because of the relative intravascular volume depletion already present in patients with preeclampsia

48.A 65 year old female who had a stroke a year back and is bed-ridden for almost 15 hours a day due to severe paresis presents to the ER with abdominal distension and pain in the left leg (calf). She could not get up to pick up the phone and 911 was called when the home nurse came to her in the morning. SHe has been having the distension for almost 2-3 weeks but now she finds it intolerable and hurts when she breathes.PE: Abd: Ascites +++, Liver enlarged +++, Spleen enlarged ++, no spider angiomata present.Leg: Left foot has no edema, left leg - calf is extremely tender and DOppler confirms DVT. Right leg has no edema, No vulvar edemaCVS: Right lung bas has minimal rales , no pain, (no chest pain in the HPI), NO JVD, NO neck vein distension
Temp - normal, Pulse - 94, RR - 30THE CAUSE OF ASCITES IS:a).Congestive cardiac failureb).Pulmonary Embolism and Right HFc).DVT moving into the systemic circulation*d).Protein C deficiencye).Atherosclerosisf).Nephrotic syndromeg).Cirrhosis secondary to HCV infectionExclusion:JVD is not raised - this alone excludes - CCF, Pulmonary embolism causing an acute Right heart failure and all other causes of increased pre load with congestion
There is no lower limb edema and no anasarca. This proves that there is no decreased albumin in the blood.That rules out Nephrotic syndrome. Also in Cirrhosis, the edema is mainly ascites due to portal hyper tension. If Generalized edema develops, it is due to decreased albumin production by the diseased liver. So this also rules out Cirrhosis to some extent. Also in Cirrhosis - liver is not palpable ( liver is palpable only in acute non-fulminant hepatitis. But they do not raise Portal pressure so much to cause dyspnoea)
USMLE gives hints in the questionas here. The guy has DVT ( no hx that the person had a prior episode of DVT or not).
Embolus going into circulation can causae an IVC clot and that causes pedal edema FIRST and later the pressure mounts inn the hepatic veins.
Another condition that can show like this is Acute alcoholic hepatitis - but no alcohol history.

50.A 35-year-old woman with amenorrhea is found tohave an enlarged pituitary gland. Her prolactinlevel is 80 ng/L (normal, less than 20 ng/L), andher thyrotropin level is 100 µU/mL (normal, 0.5 to4.5 µU/mL). Which of the following is the besttreatment option for this patient?A) Administration of bromocriptine
*B) Administration of L-thyroxine
C) Irradiation of the pituitary gland
D) Resection of the pituitary gland
E) Use of oral contraceptivesprolactin level above 100 confirms ur diagnosis of proclactiemia.Since here its 80 it might just be due to associated hypothyriodism. Hypothyroidism is confirmed by tsh levels being above 20. so now my answer is give thyroxine
