[In-hospital stroke: clinical profile and expectations for treatment].

Introduction: In-hospital strokes have been poorly reported. They provide an opportunity to shorten intervals for thrombolysis. Our proposals were: a) to describe their clinical features and neurological assessment, and b) regarding thrombolysis, to analyze potential candidates and exclusions at a general tertiary hospital, just before its approval/implementation at the center.

[Risk of the development of dementia after interruption of zidovudine treatment].

Background: Epidemiologic data suggest that zidovudine (ZDV) could prevent the AIDS dementia complex (ADC), but this hypothesis has been specifically studied.

Patients And Methods: We have reviewed the medical records of all patients with human immunodeficiency virus (HIV) infection admitted to our section between January 1990 and December 1993 who were diagnosed with ADC, and we have compared them to those of a control group with regard to the interruption of ZDV at least 3 months before. Controls were selected from the remaining HIV-related admissions, matched by calendar year, CD4-cell count and previous HIV-disease stage.
