[Risky practices associated with HIV infection of seamen who travel in sub-Saharan West Africa]. / Prácticas de riesgo para la infección por los VIH en marineros que viajan al Africa occidental subsahariana.

We report the results of the epidemiological and serological studies concerning HIV-1 and HIV-2 infections carried out in a group of 203 seamen who visited the sub-Saharan area (west coast of Africa). The following risky practices were detected: history of drugs abuse 8 (3.9%), transfusion 3 (1.5%), use of parenteral medicines in Africa 80 (39.4%), surgery in Africa 41 (20%), tattoos 18 (8.9%). Sexual behavior: stable couple 180 (88.7%), number of sexual couples 4.2 +/- 6, contacts with prostitutes 108 (53%), contacts with prostitutes in Africa 83 (40.9%), others heterosexual contacts 58 (28.6%), homosexual 1 (0.5%), history of VD 34 (16.7%), 94% of the seamen never (or occasionally) used the preservative with theirs couples and 73% of them didn't use it with others contacts. Four seamen were HIV-1 (+): contacts with prostitutes in Africa 2, use of parenteral medicines in Africa 1 and drugs abuse 1. We observed a high prevalence of risky practices associated with HIV-1 infection between seamen population. It is interesting to remark the importance of heterosexual transmission and the use of parenteral medicines.

[Prognosis after myocardial infarction]. / Pronostico postinfarto del miocardio.

A group of 102 patients (66 males, age 62 +/- 11 years) surviving an acute myocardial infarction was followed for 6 to 48 months. Survival was analyzed by the method of Kaplan Meier and Cox analysis was used to identify prognostic factors. Thirteen patients died during follow up: 3 had sudden death, 3 a stroke, 3 died from heart failure, 3 had reinfarction and cardiogenic shock and 1 died from cholangitis. Most deaths occurred in the first few months of follow up. Survival was 92% at 6 months, 90% at 1 year, 88% at 2 years and 86% at 3 years after infarction. Single variable analysis disclosed a 2 to 3 fold late mortality risk associated to the presence of age over 60 years, old myocardial infarction, hypertension, diabetes mellitus and ventricular tachycardia or fibrillation during the acute phase. Greater than 3 fold risk was seen for patients developing heart failure or shock during myocardial infarction. Heart failure was the only statistically significant risk factor identified by multivariate analysis.
