[Disseminated candidiasis in parenteral drug addicts. Report of 15 cases]. / Candidiasis diseminada en adictos a drogas por vía parenteral. Presentación de 15 casos.

Fungic infections related to parenteral use of drugs increased significantly from 1980 on with the description of the disseminated candidiasis syndrome. Associated to the administration of brown heroin, this syndrome is characterized by the development of cutaneous, ocular and osteoarticular infections, isolated or combined, by Candidas albicans. We present 15 patients with disseminated candidiasis: 12 developed ocular affection (10 endophthalmitis and 2 chorioretinitis): 9, cutaneous lesions and 3 osteoarticular affection (3 costochondritis and one hip arthritis); 8 presented simultaneous infections in several locations. The biopsy and culture of the cutaneous lesions was the most profitable test in order to establish the microbiological diagnosis. We comment on the main etiopathogenetic, clinical, diagnostic and therapeutic aspects of the disseminated candidiasis syndrome.

[Beta-thromboglobulin levels and atherosclerosis. Its relationship with the presence of risk factors]. / Niveles de beta-tromboglobulina y aterosclerosis. Su relación con la presencia de factores de riesgo.

In order to evaluate whether plasma beta-thromboglobulin (as a marker of the degree of platelet function) in patients presenting clinically evident atherosclerosis is related to the presence or absence of different risk factors (smoking habit, arterial hypertension, hypercholesterolemia, diabetes, hypertriglyceridemia, obesity, hyperuricemia, alcoholism), 40 patients have been studied in whom mean beta-thromboglobulin levels was 54 +/- 25.56 ng/ml, which is very superior to levels considered normal. However, the presence of one or more risk factors did not lead to significant variations in b-thromboglobulin concentrations, and no differences were found either when each risk factor was considered separately. The positive correlation (r = 0.98; p less than 0.01) between beta-thromboglobulin and apo B levels is highlighted. The results suggest that platelet hyperfunction seems to be due to a greater extent to the atherosclerotic process rather than to the existence of a particular risk factor.
