*a. bereavement
b. acute stress ds
c. depression
d. acute adjustamnet ds
e. PTSD
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?
Hemophilia
Neurosyphilis
*Antiphospholipid syndrome
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. Physical examination is normal except for a large, nodular uterus compatible in size with a 16-week pregnancy. Laboratory tests, including hemoglobin and urine hCG levels, are all normal. 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.

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.

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.
You should
*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
1 asymptomatic renal stone
*2 benign prostatic hyperplasia
3 bladder cancer
4 coagulopathy
5 urinary tract infection
10. 18 y/o pregnant, first trimester, blood pressure 120/75, has seizures,
which is the diagnosis in this case
a eclampsia
*b.epilepsy
11. A 5 year-old has anemia with Hb 6.2g. You gave iron. After one week treatment follow up, what do you order?
a] hct
b] iron
*c] Reticulocyte count
d] Hb
e] vitamin B12
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?
a. Hypertension
b. Smoking
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
14. A 32 weeks pregnant pt with severe cervical dysplasia. Next
1. treatment
2. no treatment
Due pregnancy the immunity os decreased so there may be flare up of cervical dysplasia.
More paps test is done during pregnancy that may be a reason for more diagnosis of cervica dysplasia.
So, HPV should be studied and close observation is required.
Two options
Cryotheraty during pregnancy or after the delivery with good outcome

ref: Kaplan Lectures
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 edema
CVS: 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 - 30
THE CAUSE OF ASCITES IS:
a).Congestive cardiac failure
b).Pulmonary Embolism and Right HF
c).DVT moving into the systemic circulation
*d).Protein C deficiency
e).Atherosclerosis
f).Nephrotic syndrome
g).Cirrhosis secondary to HCV infection
Exclusion:
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.
49. A 62-year-old man with metastatic prostate cancer
has a rising PSA level despite treatment with
leuprolide and flutamide. What should be the first
step in managing this asymptomatic man with hormone-
refractory disease?
A) Treat with aminoglutethimide
*B) Discontinue flutamide to attempt to obtain an
antiandrogen withdrawal response
C) Discontinue leuprolide
D) Treat with diethylstilbestrol
E) Perform an orchiectomy
50.A 35-year-old woman with amenorrhea is found to
have an enlarged pituitary gland. Her prolactin
level is 80 ng/L (normal, less than 20 ng/L), and
her thyrotropin level is 100 µU/mL (normal, 0.5 to
4.5 µU/mL). Which of the following is the best
treatment 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 contraceptives
prolactin 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
51. A 53 year old woman presents to the emergency room with abdominal pain, nausea, vomiting, hypotensive, tachycardia and disoriented. A FSG check comes back as >500. You quickly get a urine sample and analyze it with a dipstick. It shows the following results:
Specific Gravity=1.005/pH=5.5/1+protein/4+glucose/+ketones/0 RBC,WBC, epithelials cells.
You promptly get IV access and draw the necessary blood studies. Your next step would be to:
a.Give a Normal Saline bolus and run IV fluids wide open
b.Do (1) and give 10 units of regular insulin IV and start an insulin drip at 0.1units/kg/hr
c.Do (1) and give 10 units of NPH and start an insulin drip at 0.1 units/kg/hr
d.Do (1) and start on Diabeta 10 mg
*e.Do (1) await lab results and observe
Diabetic Ketoacidosis
This patient is obviously in D.K.A. as evidenced by high serum glucose, glucosuria and ketonuria. What ones needs to do now is to resusciate the patient with FLUIDS! To reverse the ketone production that is contributing to the acidosis the patient also needs insulin BUT initially this is secondary to fluid resusciation. YOU DO NOT WANT to be giving insulin to any patient without documented electrolytes. With the acidosis and dehydration, patients become potassium depleted. The committment acidosis will contribute to "shifting" potassium out of the cell giving you a falsely elevated potassium. The danger is if a patient is severly potassium depleted in the face of an acidosis, with the fluids correcting the acidosis, the insulin is going to shove more potassium into the cells thus acutely lowering the serum potassium level to potentially dangerous levels. If the potassium gets lower than 2.0-2.5 one is prone to provoking lethal arrhythmias.

52. A 50 year old white man with a history of "mild" heart attacks presents to the emergency department with a 1 hour history of "crushing" chest pain associated with nausea, shortness of breath, diaphoresis and radiation into the left arm and neck. An old EKG from 3 months ago was normal.
As the E.D. physician you would:
a.Give the patient a "white slider" (a mixture of lidocaine & maalox)
b.Give the patient some Valium and tell him that the pain is all in his head
*c.Give the patient an aspirin
d.Give the patient an aspirin, start Heparin and assess for thrombolytic contraindications
e.Give the patient a sublingual nitroglycerin tablet
f.Give the patient a dose of steroids and start on Ibuprofren
53. Ophthalmoscopic examination shows a pale and swollen optic disk of the left eye with scattered flame-shaped hemorrhages in the vicinity of the disk. An afferent pupillary defect is present in the left eye. The most likely cause for these findings is:
*A - Ischemic optic neuritis
B - Talc embolus due to IV heroin abuse
C - Glioma with papilledema
D - Retinal artery occlusion
E - Diabetic neuropathy
Anterior ischemic optic neuropathy involves interruption of the blood flow in the short posterior ciliary arteries that supply the optic disk. This results in a severe loss of vision, altitudinal visual field defects, and a pale, swollen optic disk, with peripapillary hemorrhages.An afferent pupillary defect (APD) occurs when the nerve pathways to the brain fail to properly transmit messages.If an APD is severe (dilation of the affected pupil), it generally indicates optic nerve disease such as ischemic optic neuropathy, optic neuritis, severe glaucoma, central retinal artery or vein occlusion, or in rare cases, a lesion of the optic chiasm or tract due to a pituitary tumor or stroke.
54. A 35 year old woman comes to the ER complaining of palpitations . An EKG shows A FIb. She says that she has NEVER experienced this before and has never been diagnosed like this before. You as the resident examine her -irregularly irregular pulse, a diffuse swelling in her neck. SHe has a pronounced stare as if her eyes are popping out. She also gives history of feeling hot and sweaty and easy arousability. The labs show her TSH level as <0.1 mu/ml (normal: 0.5-5) and free T4 as 6 ng/dl (N = 0.8 to 2). You find her hyperthyroid and remember your endocrine class that U diffuse enlargement with hyperthyroidism can be due to Graves disease and sub acute thyroiditis. As the examination was confusing for you, you call the endocrinologist. The Most likely advice from the endocrinologist will be:
a). Close observation
*b). Start propyl thiouracil
c). 24 hour radioactive iodine uptake scan
d). Start methimazole and also send her for radio iodine ablation now
e). Reassurance only
methimazole for 2-3wks and then ablation. Be careful with the word NOW...you cannot give both metimazole and ablation.
55. A 72 year-old Iranian-born nursing home resident is brought to your clinic because of an abnormal tuberculin test. The patient has Alzheimer's disease, but is physically in good condition. When he was admitted to the nursing home one year ago his tuberculin test was negative at 4 mm. On this year's routine evaluation, his tuberculin test is 13 mm. What is the most likely cause for the positive PPD?
A Active tuberculosis
B Recent infection with Mycobacterium tuberculosis
C Recent infection with nontuberculous mycobacterium
D Inaccurate recording of PPD in the medical record
*E. Recall of waned immunity (booster phenomenon)
This is Booster phenomenon
Booster phenomenon:
Patient had TB while young OR had contact with a open case while young. The system made antibodies in either case. After a period of time, the memory cells wane and the memory of the initial infection is forgotten.
WHen the first PPD is given, the system remembers the initial event in one to two weeks. SO the second PPD comes a positive.
This is differentiated by ( done in many nursing homes and other places where routine PPD testing is done yearly)
DO PPD for the first time

78. A 28-year-old man decides to donate a kidney to his brother, who is in chronic renal failure, after HLA typing suggests that he would be a suitable donor. He is admitted to the hospital, and his right kidney is removed and transplanted into his brother. Which of the following indices would be expected to be decreased in the donor after full recovery from the operation?
Creatinine clearance
*Renal excretion of creatinine
Creatinine production
Daily excretion of sodium
Plasma creatinine concentra
Explanation of Answer:
Because creatinine is freely filtered by the glomerulus, but not secreted or reabsorbed to a significant extent, the renal clearance of creatinine is approximately equal to the glomerular filtration rate (GFR). In fact, creatinine clearance is commonly used to assess renal function in the clinical setting. When a kidney is removed, the total glomerular filtration rate decreases because 50% of the nephrons have been removed, which causes the creatinine clearance to decrease. In turn, the plasma creatinine concentration increases until the rate of creatinine excretion by the kidneys is equal to the rate of creatinine production by the body. Recall that creatinine excretion = GFR x plasma creatinine concentration. Therefore, creatinine excretion is normal when GFR is decreased following removal of a kidney because the plasma concentration of creatinine is elevated.
Creatinine is a waste product of metabolism. Creatinine production is directly related to the muscle mass of an individual, but is independent of renal function.
The daily excretion of sodium is unaffected by the removal of a kidney. The amount of sodium excreted each day by the remaining kidney exactly matches the amount of sodium entering the body in the diet.
79. A 24-year-old AIDS patient develops chronic abdominal pain, low-grade fever, diarrhea, and malabsorption. Oocysts are demonstrated in the stool. Which of the following organisms is most likely to be the cause of the patient’s diarrhea?
Diphyllobothrium latum
Entamoeba histolytica
*Giardia lamblia
Isospora belli
Microsporidia
Explanation of Answer:
All the organisms listed are protozoa. There are two intestinal protozoa specifically associated with AIDS that can cause transient diarrhea in immunocompetent individuals but can cause debilitating, and potentially life-threatening, chronic diarrhea in AIDS patients. These organisms are Isospora belli, treated with trimethoprim-sulfamethoxazole or other folate antagonists) and Cryptosporidium parvum (no treatment currently available).
Diphyllobothrium latum is the fish tapeworm and occasionally causes diarrhea.
Entamoeba histolytica and Giardia lamblia are both causes of diarrhea, but they are not specifically associated with AIDS.
Microsporidia are a protozoan cause of diarrhea but produce spores rather than oocysts

85. The diagnosis of cervical incompetence has traditionally been made on the basis of an obstetric history consistent with passive and painless midtrimester dilation of the cervix. The presence of uterine contractions, bleeding, ruptured membranes, and intra-amniotic infection do not necessarily exclude the diagnosis of an incompetent cervix, as it is often difficult to ascertain whether these latter complications preceded or followed the dilation. Cervical cerclage is still the best treatment for cervical incompetence. Which of the following is an indication for cerclage
A Cerclage is indicated solely based on risk factors or prior cerclage placed for doubtful indications
*B Clinical evidence of extensive obstetric trauma to cervix
C Chorioamnionitis
D Premature rupture of membranes

92. A 21-year-old woman is a restrained passenger in a high-speed motor vehicle collision and presents with neck, abdominal, and back pain, with normal vital signs. She is 32 weeks’ pregnant. Which of the following statements is incorrect?
A. Fetal monitoring is important to detect early fetal distress.
*B. Traumatic placental abruption is almost always associated with vaginal bleeding.
C. Appropriate radiological studies should not be withheld.
D. Ultrasound is not very accurate in detecting placental abruption
Answer: B
In blunt trauma, 50% to 70% of fetal losses result from placental abruption. Fetal mortality in abruption cases is about 50%. Classic clinical findings in placental abruption may include vaginal bleeding, abdominal cramps, uterine tenderness, amniotic fluid leakage, maternal hypovolemia, and fetal distress. However, in some trauma series, up to 60% of placental abruption has no associated vaginal bleeding. Fetal monitoring is a sensitive monitor for fetal distress. Appropriate radiologic studies should never be withheld when necessary to properly care for the mother. Ultrasound is less that 50% accurate in detecting abruption.
*93. A 6-year-old girl ingests an unknown volume of a pesticide called Sevin(®)(a carbamate anticholine-sterase inhibitor) and presents with clinical evidence of toxicity, including pinpoint pupils, vomiting, diarrhea, severe weakness, and heavy oral secretions. Besides prompt intubation and ventilation, appropriate treatment includes which of the following?
A. atropine
B. methylprednisolone
C. pralidoxime
D. epinephrine
Answer: A
Carbamates are reversible acetylcholinesterase inhibitors that lead to hyperstimulation of nicotinic and muscarinic receptors in the autonomic nervous system. The classic presentation includes hypersecretion from all orifices along with diffuse weakness and various central nervous system manifestations. Supportive care, decontamination, and intravenous atropine in high doses are the mainstays of therapy. Pralidoxime is not indicated for carbamate poisoning.
94. Which of the following is appropriate initial antihypertensive therapy for the listed hypertensive emergency in a patient with a blood pressure of 210/116 mm Hg?
A. eclampsia—captopril
B. aortic dissection—nitroprusside
*C. clonidine withdrawal—phentolamine
D. phentolamine cocaine intoxication—propanolol
Answer: C
Eclampsia is a hypertensive emergency in pregnancy with secondary seizures. Traditionally, it has been treated with magnesium sulfate and intravenous hydrala-zine, although labetalol and nicard-ipine are gaining acceptance as appropriate antihypertensive therapy in this setting. Captopril and other angiotensin-converting enzymes are contraindicated in pregnancy because of increased fetal mortality. Antihypertensive therapy for aortic dissection has as a goal not only blood pressure control but also reduction of cardiac contractility to decrease the shear force from the pulse pressure of each contraction. Beta-blocker therapy with propanolol or the shorter-acting, more titratable esmolol is the therapy of choice. Nitroprus-side is inappropriate initial therapy for aortic dissection because it causes reflex increases in heart rate and cardiac contractility. Cocaine intoxication leads to cate-cholamine excess. The resultant severe hypertension will be increased by beta-blocker therapy alone. Propanolol is contraindicat-ed for initial therapy of cocaine-induced hypertension. Clonidine withdrawal is also a state of cate-cholamine excess and is appropriately treated initially by an alpha-blocker such as phentolamine.4,5
95. A depressed 28-year-old woman with AIDS and pulmonary tuberculosis presents with recurrent generalized seizures. She has not stopped seizing despite large doses of lorazepam and fosphenytoin 1 g intravenously. Which of the following should be considered quickly in the patient’s care?
A. thiamine
B. sodium bicarbonate
C. vecuronium with ventilatory support
D. pyridoxine
Answer: D
Pyridoxine (vitamin B6) is the antidote of choice for isoniazid toxicity, a cause of intractable seizures unresponsive to standard therapies. An initial dose of 5 g in adults and 1 g in children is indicated in unknown overdose with intractable seizures.6 Paralysis by neuromuscular blocking agents will hide the motor activity but will not protect from the continuous neuronal hyperstimulation of ongoing seizures, and if used, requires ongoing electroencephalogram monitoring.

Feverfew
Background: Feverfew is a bushy perennial herb. Parthenolide and glycosides are thought to be its active components.
Medicinal Claims: Feverfew is used to prevent migraine headaches. It may reduce inflammation. Feverfew reduces the clotting tendency of platelets (cell-like particles in the blood that help stop bleeding by forming clots). Evidence from two of three relatively small but well-designed studies supports these effects. Differences in study findings may reflect the different formulations of feverfew used. In studies of people with arthritis, feverfew did not relieve symptoms.
Possible Side Effects: Mouth ulcers and skin inflammation (dermatitis) may occur. Taste may be altered, and heart rate increased. Feverfew may interact with anticoagulants, drugs used to manage migraine headaches, and nonsteroidal anti-inflammatory drugs (NSAIDs). It may reduce the absorption of iron. Feverfew is not recommended for children or for women who are pregnant or breastfeeding.

Which of the following is accepted therapy for this illness?
A. penicillin
B. prednisone
*C. acetylsalicylic acid
D. azithromycin
Kawasaki syndrome has an abrupt onset, with fever as high as 104°F (40°C) and a rash that spreads over the patient's chest and genital area. The fever is followed by a characteristic peeling of the skin beginning at the fingertips and toenails. In addition to the body rash, the patient's lips become very red, with the tongue developing a "strawberry" appearance. The palms, soles, and mucous membranes that line the eyelids and cover the exposed portion of the eyeball (conjunctivae) become purplish-red and swollen. The lymph nodes in the patient's neck may also become swollen. These symptoms may last from two weeks to three months, with relapses in some patients. The physician will first consider the possible involvement of other diseases that cause fever and skin rashes, including scarlet fever, measles, Rocky Mountain spotted fever, toxoplasmosis (a disease carried by cats), juvenile rheumatoid arthritis, and a blistering and inflammation of the skin caused by reactions to certain medications (Stevens-Johnson syndrome). Kawasaki syndrome is usually treated with a combination of aspirin, to control the patient's fever and skin inflammation, and high doses of intravenous immune globulin to reduce the possibility of coronary artery complications.

c. Administer a TST, perform a CXR, administer INH, and reevaluate in 3 months.
d. Reevaluate after 3 months.
*e. None of the above.
A child with a positive Mantoux test result but without active disease is a candidate for isoniazid prophylaxis. Active disease is excluded by a normal chest radiograph and a lack of symptoms suggesting TB disease.
Special pediatric cases should be considered candidates for isoniazid prophylaxis even if they lack documentation of a positive Mantoux test:
Newborn prophylaxis: Infants whose mothers have active disease (even if noncontagious) and infants whose mothers have a positive Mantoux test but do not have active disease (preventive therapy can be discontinued after the entire family is demonstrated to have negative tuberculin skin tests)
Children who are both anergic or HIV-positive and from populations where the prevalence of TB infection is higher than 10% (eg, injection drug users, homeless persons, migrant laborers, and individuals from Asia, Africa, or Latin America)
Children who have had close contact within the past 3 months with a person with infectious TB."

MANAGEMENT OF PATIENTS WITH HIT(Heparin induced Thrombhocytopenia)
There are few prospective randomized studies on which to base recommendations regarding the management of HIT. The following guidelines are based on the best available data in January 2002. Patients with HIT are best managed by, or in consultation with, a specialist experienced in managing HIT.
a. All heparin should be discontinued in patients with HIT. This includes unfractionated and low-molecular weight heparins by any route, heparin flushes, and vascular catheters that are heparin-coated.
b. Anticoagulation with an alternative anticoagulant - either danaparoid, lepirudin, or argatroban (listed in historical order of availability) should be given if the original indication for which heparin was initiated still exists (see #6. Anticoagulants for HIT).
c. Patients who have new, progressive or recurrent thrombosis associated with HIT (HIT-associated thrombosis) should be treated with therapeutic-dose anticoagulation with danaparoid, lepirudin, or argatroban. (see #6. Anticoagulants for HIT). Therapy should not be delayed for the results of laboratory testing if the clinical suspicion of HIT is strong.
d. Danaparoid, lepirudin, or argatroban should be strongly considered in patients with HIT even in the absence of thrombosis. Patients with HIT remain at high risk of thrombotic complications for several days or weeks after cessation of heparin.
e. Warfarin should be avoided in acute HIT unless it is used in combination with therapeutic-dose danaparoid, lepirudin, or argatroban. Warfarin has been associated with worsening venous thrombosis, venous limb gangrene, and/or skin necrosis when used alone or in combination with ancrod in acute HIT. However, warfarin is appropriate for longer term anticoagulation in patients with HIT and thrombosis. Warfarin should be delayed until therapeutic anticoagulation with danaparoid, lepirudin or argatroban is achieved, and ideally, until there is substantial resolution of the thrombocytopenia. Warfarin-induced thrombotic complications have been described in patients in whom the alternative anticoagulant was stopped prior to resolution of thrombocytopenia. The optimal duration of anticoagulation in patients with HIT and thrombosis is not known.

a) give ca gluconate
*b) digiband
c) take digoxin levels
Guide treatment of patients with digoxin toxicity by their signs and symptoms and the specific toxic effects. Treatment should not necessarily be determined by digoxin levels alone. Therapy ranges from simply discontinuing digoxin therapy for stable patients with chronic toxicity to Fab fragments, pacemaker, antiarrhythmic drugs, magnesium, and hemodialysis for acute severe ingestions
Digoxin Fab fragments (Digibind) are generally indicated for the following:
Arrhythmias associated with hemodynamic instability.
Altered mental status attributed to digoxin toxicity.
Hyperkalemia with K+ greater than 6 mEq/L.
Serum digoxin level greater than 10 ng/mL in adults at steady state (ie, 6-8 h postingestion).

*A) Discuss options regarding valve replacement
b) Suggest Treatment with beta blockers
C)observation with Antibiotic prophylaxis for dental Procedures.
d)Advice abstinence from exercise and stressful activitie
Since this patient has palpitations along with some mitral regurge,that means the complications have started to develope.
The overwhelming majority of people with MVP are free of symptoms and never develop any noteworthy problems. However, it is important to understand that in some cases mitral regurgitation, the flow of blood back into the left atrium, can occur. Where mitral regurgitation has been diagnosed, there is an increased risk of acquiring bacterial endocarditis, an infection in the lining of the heart. To prevent bacterial endocarditis many physicians and dentists prescribe antibiotics before certain surgical or dental procedures.
Patients with significant mitral regurgitation should be followed more closely by their physician so that medical therapy and, if necessary, surgery, can be pursued at the appropriate time

128. A 66-year-old woman who has previously been healthy undergoes emergency surgery for a ruptured abdominal aortic aneurysm. Intraoperatively she requires 8 units of packed red blood cells to maintain her blood pressure and hematocrit. After surgery she is hemodynamically stable. On the third postoperative day she appears jaundiced, but abdominal examination is unremarkable and she is afebrile. Total serum bilirubin concentration at this time is 141 mol/L (8.3 mg/dL) [direct, 107 mol/L (6.3 mg/dL)]. Serum alkaline phosphatase level is 6 kat/L (360 U/L), and serum AST level is 0.85 kat/L (51 Karmen units/mL). The most likely explanation for the woman's jaundice is
A: a stone in the common bile duct
B: halothane hepatitis
C: posttransfusion hepatitis
D: acute hepatic infarct
*E: benign intrahepatic cholestasis
answers:
A) no pain, no temperature ( Charcot triad)
B) halothane could be type 1 mild or type 2 fulminant liver failure -- type 1 has no jaundce
C) posttransfusion hepatitis -- no viral serology
D) hepatic infarct - knockout part of the liver the other part will compensate, no jaundice
129. 16 year old high school drop out did not have periods for last 3 months. She is sexually active with one patner for 1 year. Does not use contracptives. Preg. test positive.
The reason that this adolescent's failure to use contraceptive
A. Concern about weight gain
B. Cost of Contraception
C. Patner's opposition to contraception
*D.Concern about confidentiality
E.Desire to become pregnant
here is the answer as well:
Other factors that contribute to lack of contraceptive use include adolescent developmental issues such as reluctance to acknowledge one's sexual activity, a sense of invincibility (belief that they are immune from the problems or issues surrounding sexual intercourse or pregnancy), and denial of the possibility of pregnancy and misconceptions regarding use or appropriateness of contraception. However, an adolescent's level of knowledge about how to use contraception effectively does not necessarily correlate with consistent use. Some of the reasons given by adolescents for the delay in using contraception are fear that their parents will find out, ambivalence, and the perception that birth control is dangerous.5,22

131. 65-year-old man presents because his wife notes that his eyes are becoming yellow. On further questioning, the patient complains of epigastric discomfort, dark urine, light stools, and pruritus. Past medical history and physical examination are unremarkable. Laboratory tests confirm the clinical impression of an elevation in the serum level of conjugated bilirubin. Abdominal ultrasound demonstrates a mass in the head of the pancreas and enlargement of the common bile duct. Chest x-ray and abdominal-pelvic CT disclose no additional abnormalities. A CT-guided needle biopsy of the mass obtains tissue that on pathologic examination reveals neutrophils and fibrous elements. Which of the following procedures would be most reasonable at this point?
*A. Another attempt at CT-guided needle biopsy.
B. Radiation therapy.
C. Celiac angiography.
D. Percutaneous placement of biliary stent.
E. Repeat CT in 2 to 3 months.
Dynamic contrast spiral CT and MRI detect a mass in over 80% of cases and are helpful on delineating the extent of the tumor and allowing for percutaneous fine needle aspiration for cytologic studies and tumor markers.
Selective celiac and superior mesenteric arteriography may demonstrate vessel invasion by a tumor, a finding that would interdict attempts at surgical resection,but is less widely used since the advent of dynamic CT and endoscopic ultrasonography, which is emerging as the most accurate means of demonstrating venous or gastric invasion.

134.67-year-old white female has an intermittent history of sharp, lancinating pains at the head of the third metatarsal. She initially experienced a burning sensation with some occasional numbness of the third toe, and later found that removing her shoe would frequently alleviate the pain. Her physical examination is within normal limits except for tenderness at the head of the third metatarsal in the web space between the third and fourth metatarsals.
The most likely diagnosis is
diabetic neuropathy
metatarsal stress fracture
*Morton's neuroma
avascular necrosis of the second metatarsal head

1.treadmill
2.persantine
*3.dobutamine.
Remember, first line test, if exercise is c/i >> adenosine or dipyridamole
Pharmacologic stress Myocardial Perfusion Imaging:
- Pharmacologic stress agents are classified as either vasodilator or
inotropic/chronotropic drugs
- Vasodilators, which include adenosine, dipyridamole, and adenosine
triphosphate (ATP, a precursor of adenosine), produce primary coronary
vasodilation.
*Adenosine and dipyridamole are equally effective, but adenosine has the
advantages of a very short half-life, rapid reversal of side effects after the
test is completed, and possibly more predictable vasodilatation.
-Inotropic/chronotropic agents include dobutamine (with or without atropine)
- Adenosine, dipyridamole, and dobutamine have similar accuracy.
-A vasodilator is usually the first choice for stress exercise testing, with myocardial
perfusion in patients who are unable to undergo treadmill stress.
-Dobutamine is used when vasodilators are contraindicated and in patients who have
chronic obstructive pulmonary disease or asthma (adenosine promotes
bronchospasm) or are taking drugs that interfere with the test.
- Dobutamine can be combined with both echocardiography and perfusion imaging,
while vasodilator stress is best suited for nuclear perfusion imaging because of its
lower sensitivity with echocardiography.
- Perfusion imaging is commonly performed with technetium (Tc)-99m sestamibi, Tc-
99m tetrofosmin, and thallium 201.

137. Eleven days after a massive stroke, patient does not have spontaneous respirations or response to any stimuli. Neurologic evaluation indicates that he is unlikely to regain consciousness. He has appointed his common law spouse to make the decisions about his health care by means of a living will in which he indicated that he does not want his life to be maintained using futile medical care. This was executed one and a half years ago while they lived in another state.
Patient’s spouse has requested that his hydration and nutritional support be withdrawn. The doctor treating the patient has strong moral convictions against terminating any kind of life support.
In this situation which of the following scenarios would be appropriate for the physician to follow?
A. He should continue to treat the patient according to his convictions since he is not obligated to practice medicine contrary to his moral beliefs.
B. He should comply with the requests of the patient’s spouse.
C. He can safely continue to treat patients as he wishes because the living will of the patient was executed in another state and it was done so more than 1 year ago, both of which make it invalid in the present situation.
*D. He should transfer the care of the patient to another physician who is willing to comply with the wishes of the patient’s wife and his own expressed in the living will.
Usually Proxy rules. But if there is a living will then both of them should be considered.
If Proxy and Living Will go together then it is fine. If they conflict, call ethics committee

Hemoglobin SC Disease. Inheritance of one beta S gene and one beta C gene results in Hemoglobin SC Disease. These individuals have a mild hemolytic anemia and moderate splenomegaly (enlargement of the spleen). Persons with Hgb SC disease may develop the same vaso-occulsive (blood vessel blocking) complications as seen in sickle cell anemia, but most cases are less severe.
Hemoglobin S – beta thalassemia. Sickle cell – beta thalassemia varies in severity, depending on the beta thalassemia mutation inherited. Some mutations result in decreased beta globin production (beta+) while others completely eliminate it (beta0). Sickle cell – beta+ thalassemia tends to be less severe than sickle cell – beta0 thalassemia. Patients with sickle cell – beta0 thalassemia tend to have more irreversibly sickled cells, more frequent vaso-occlusive problems, and more severe anemia than those with sickle cell – beta+ thalassemia. It is often difficult to distinguish between sickle cell disease and sickle cell – beta0 thalassemia.

The growth of a nodule is conventionally defined as the doubling time (time required for its volume to double) and corresponds to an increase in diameter by a factor of 1.26.
In general, doubling times > 16 months or < 1 month are associated with benign processes.
in this case the nodule grew for 2 monts to 2cm ( 1cm/mo ) which rather fast..keep in mind that benign proceses grow either too slow or too fast. Malignancy grows steady, at predictable rates. In any case observation is required per 6mo to see how fast its growing.
146. A 26-year-old man is admitted to the hospital after accidental ingestion of corrosive alkali liquid. He denies any past medical or surgical history. The day before admission, he was at a party with his friends where he consumed a lot of alcohol. At the end of the party, he returned home and accidentally ingested corrosive alkali liquid from a bottle, mistaking it for a bottle of water. At the time of admission to the hospital, he complained of substernal chest pain and that he was feeling "really ill". Initial gastrointestinal contrast study with water-soluble contrast did not reveal a gastrointestinal leak or perforation. His vitals are stable with a tachycardia of 90/min. The next best step in management is to
A. continue to observe him in the hospital
B. order a CT scan of the chest
C. order an electrocardiogram
D. order an upper gastrointestinal study with barium
*E. perform an upper gastrointestinal endoscopy
Endoscopy should be performed as soon as possible after admission to assess the magnitude and extent of injury ...
The use of emetics is contraindicated because vomiting reexposes the esophagus and the oropharynx to the caustic agent, further aggravating injury.
Neutralizing agents (weakly acidic or basic substances) should not be administered because damage is generally instantaneous. Furthermore, neutralization releases heat which adds thermal injury to the ongoing chemical destruction of tissue
Nasogastric intubation to remove any remaining caustic material is contraindicated because it may induce retching and vomiting which can compound injury and possibly lead to perforation of the weakened esophagus or stomach.

182. A patient with chronic alcohol and benzodiazepine abuse admitted and developed agitation after 10 days. The tx of choice:
a-Haloperidol
*b-Lorazepam
c-Phenobarbitol
Advanced sedative-hypnotic withdrawal (eg, markedly abnormal vital signs, delirium) should be treated rapidly and with sufficiently large doses of medication to suppress the withdrawal. Medications with a rapid onset of action should be used and may be given intravenously for immediate effect. Lorazepam and diazepam are good choices since they have a rapid onset of action when given intravenously, although they have a shorter duration of action than when given orally.
After stabilization with rapidly-acting medications, the patient can be switched to an equivalent dose of a long-acting medication such as phenobarbital. The awake patient will not undergo significant respiratory depression from the withdrawal medication; at times very large doses are required (up to 700 mg of phenobarbital per day).

A)Flexing the woman's knees toward her shoulders
B)More forceful traction and fundal pressure
*C)Delivering the posterior arm
D)Rotating the head 180 degree
E)Symphysiotomy
Most interventions are intended to disimpact the anterior shoulder from behind the symphysis pubis by rotating the fetal trunk or delivering the posterior arm and shoulder. In general, the operator has up to seven minutes to deliver a previously well-oxygenated infant before an increased risk of asphyxial injury occurs ..
Delivery of the posterior arm almost always relieves impaction of the anterior shoulder and resolves the dystocia
The posterior arm should be identified and followed to the elbow, at which point pressure is applied in the antecubital fossa. This flexes the elbow across the fetal chest and allows the forearm or hand to be grasped. The arm is then pulled out of the vagina, which brings the posterior shoulder into the pelvis. If the anterior shoulder cannot be delivered at this point, the fetus can be rotated and the procedure repeated for the anterior (now posterior) arm. The greatest risk with delivery of the posterior arm is fracture of the humerus.

Studies have consistently shown that using OCs reduces the risk of ovarian cancer. In a 1992 analysis of 20 studies of OC use and ovarian cancer, researchers from Harvard Medical School found that the risk of ovarian cancer decreased with increasing duration of OC use. Results showed a 10- to 12-percent decrease in risk after 1 year of use, and approximately a 50-percent decrease after 5 years of use. This association between OC use and decreased risk of ovarian cancer has also been observed among women who have certain genetic changes in the BRCA1 or BRCA2 gene that increase their risk of ovarian cancer. |
