A-V block by an overdose of Clonidine.

The case of a young addict woman, chronically treated with Clonidine, in whom an overdose of the drug determined transient S-A and A-V conduction disturbances is reported. Such effects have been attributed to vagal hyperactivity and must be kept in mind when the drug is administered to patient of old age, with cardiac disease, or in association with digitalis. The treatment of choice is represented by forced diuresis induced either by osmotic diuretics of furosemide.

Acute renal failure as a consequence of sudden renal artery occlusion.

Acute renal failure secondary to renal artery occlusion is rare but can be reversed and is therefore important to cases to draw attention to the diagnosis and management of the condition. In one case, occlusion of the artery to a single functioning kidney was responsible for the clinical presentation; in the other, bilateral renal artery emboli were responsible. The authors present a detailed review of the English literature to determine the prognostic value of the duration of anuria preceding operation in patients with renal artery occlusion to a solitary kidney. This factor showed no correction with viability of renal tissue, functional recovery or patient survival. Surgical management offers the best prospect of success in these patients.

Use of condoms by heterosexually active drug abusers before and after AIDS education.

This study identified variables associated with increased condom use among drug abusers in a randomized trial of three AIDS educational programs in a short-term inpatient detoxification program. Participants (n = 301) completed baseline and follow-up interviews and were heterosexually active on both occasions. At baseline, 10% always, 24% sometimes, and 66% never used condoms, and this distribution changed only slightly at follow-up. Among the latter two groups, 21% increased their use. There was no differential intervention effect on changes in condom use. Women, but not men, were more likely to initiate condom use than to increase to consistent use with all partners, and to initiate use if they had multiple partners. Although beneficial attitudes and beliefs about condoms were more common among women at baseline, positive changes in these attitudes/beliefs were associated with increased condom use among men only. Among men, personal attitudes and beliefs were associated with increased condom use, while among women, perceptions of the attitudes of sexual partners were more important.
