Effect of cholestyramine on the absorption of vitamin D3 and calcium.

The absorption of 10 mug doses of vitamin D(3)-(3)H in rats was found to be decreased by the addition of cholestyramine to the diet in an amount sufficient to cause steatorrhoea. Studies in vitro suggested that the effect of cholestyramine was due to its known ability to bind bile salts and thus disrupt micelles containing vitamin D. The absorption of 1 mg (47)calcium chloride was similar in both control and cholestyramine-fed rats, whether estimated by the whole body counting or the faecal excretion technique. These findings show that the administration of cholestyramine causes a reduction in the absorption of vitamin D(3)-(3)H but not of radiocalcium.

Treatment of cholerheic diarrhea with cholestyramine and a hydrophilic colloid.

Eight patients with ileal-resection diarrhea who were being treated with cholestyramine took part in a trial comparing the effectiveness of cholestyramine with that of a hydrophilic colloid. Both drugs reduced overall stool frequency and improved consistency, but a larger dose of colloid was required. One patient planned to use the hydrophilic colloid instead of cholestyramine.

Evaluating evaluation: assessment of the American Board of Internal Medicine Resident Evaluation Form.

The American Board of Internal Medicine suggests use of a standard form to rate residents on nine dimensions (such as clinical judgment and overall clinical competence) on a scale of 1 to 9. The authors examined the psychometric evidence for reliability and validity of 1,039 ratings of 85 residents by 135 attendings in a single internal medicine residency program. Of these ratings, 95.6% were from 6 to 9. Factor analysis revealed that high correlations among the nine dimensions (r ranged from 0.72 to 0.92) resulted from a single global factor accounting for 86% of the variance. The study also examined whether the form reliably distinguishes among residents scoring between 6 and 9. Agreement among attendings rating the same individual was weak (average reliability = 0.64, by the method of James). The rating method fails to discriminate dimensions of clinical care and has low reliability for distinguishing among competent residents.
