[EX Q]: Abstract: The purpose of the study was to compare the renal effects of low doses of exogenous dopamine to assess the responsiveness of renal dopaminergic receptors in normotensive and hypertensive subjects. Eight hypertensive patients and seven normotensive volunteer subjects were studied. Inulin and para-aminohippuric (PAH) clearances, natriuresis, and fractional excretion of sodium increased significantly after intravenous dosing with dopamine (2 micrograms/min/kg) in both groups. These increases were significantly higher in hypertensive than in normotensive subjects: 31.8% +/- 3.7% vs. 16.2% +/- 1.2% for inulin clearance (P less than 0.01), 83.3% +/- 10.5% vs. 41.1% +/- 3.4% for PAH clearance (P less than 0.01), and 331% +/- 38% vs. 216% +/- 26% for natriuresis (P less than 0.01). These findings suggest hyperresponsiveness to dopamine during hypertension. This enhanced response to exogenous dopamine can be considered as a further argument favoring the existence of a deficit in dopaminergic activity during hypertension. Dopamine also induced a significant reduction in blood pressure and increased heart rate in hypertensive subjects but no significant change in blood pressure and heart rate occurred in normotensive subjects.

[EX Q]: Abstract: To acquire information about the characteristics of U.S. citizens who had recently studied medicine abroad, the Educational Commission for Foreign Medical Graduates (ECFMG) and the Association of American Medical Colleges merged independently collected data on a study group of 10,460 U.S. citizens who attended 359 medical schools in 75 foreign countries and who took their first ECFMG examination between 1978 and 1982. The study group was markedly heterogeneous: 21 percent were not U.S. citizens at birth, 32 percent did not have English as a native language, and 12 percent had two or more years of undergraduate college education in Puerto Rico. Sixty-seven percent resided in New York, New Jersey, California, Florida, or Puerto Rico, and 74 percent studied medicine in Mexico or the Caribbean. Forty-six percent passed the ECFMG examination on their first attempt, and 22 percent passed a subsequent examination. Only 45 percent had applied to a U.S. medical school, and 65 percent had taken the Medical College Admission Test. The means of the college grade-point averages, known for 39 percent of the study group, and of the scores on the admission test, known for 65 percent, were lower than those of both accepted and unaccepted applicants to U.S. medical schools in the 1976 and 1978 entering classes. The finding that 55 percent of the study group did not apply to a U.S. medical school does not support the widely held belief that most, if not all, U.S. citizens who attend foreign medical schools do so only after several unsuccessful attempts to gain admission to a U.S. school.

[EX Q]: Abstract: To better understand declining autopsy rates, data have been gathered prospectively on 1080 consecutive deaths over six years among patients admitted to a medical intensive care/coronary care unit. Overall autopsy rate was 36%. Autopsy rates declined sharply with age from 60% for those aged 16 to 34 years to 23% for those 85 and over (P less than .001). The highest rates by diagnosis were aortic aneurysm (70%), hepatic failure (52%), heart rhythm disturbance (48%), pulmonary embolism (45%), and sepsis (41%). Patients receiving major procedures had a significantly higher autopsy rate (38 versus 29%, P less than .05) but rates bore little relation to prognoses given at admission by house officers, suddenness of death, sex, marital status or year of admission. Even among intensively treated patients, autopsy rates decline strikingly with age, demanding honest re-appraisal to restore the place of autopsy in medical education, clinical research, and quality of care assessment for an increasingly elderly population.
