Heparin-associated thrombocytopenia: a prospective evaluation of 211 patients.

Two hundred eleven consecutive patients treated for acute thromboembolic disease were evaluated prospectively for the incidence of thrombocytopenia while receiving heparin treatment. One hundred patients received beef lung heparin and 111 patients received porcine intestinal mucosal heparin. All patients received a minimum of 4 consecutive days of continuous intravenous heparin, and platelet counts were determined prior to, at least twice weekly, and at the cessation of heparin therapy.

Benzodiazepine utilization in a family medicine residency program.

A study was conducted to determine the benzodiazepine-prescribing habits of residents in a family medicine training program. Data were collected from medication profiles of all patients seen at the Family Practice Center from July 1975 to February 1981. Additional demographic data (ie, age, sex) were collected on patients prescribed benzodiazepines, and prescribing behavior was validated according to the Psychopharmacological Screening Criteria Development Project.
