Acquired immunodeficiency syndrome in forensic autopsies.

From May 1985 to May 1989, 126 necropsies were performed at the São Paulo City Morgue on cadavers of individuals AIDS victims whose unnatural deaths had prompted police investigations. One hundred and nineteen males and 17 females were included. Ages were most commonly in the 20-to-30 year range. Fifty four deaths occurred in penal institutions, 29 deaths resulted from suicides, 17 deaths from manslaughter, 17 deaths were considered suspicious, 5 willful murders and 4 others also considered suspicious because corpses were found in advanced stages of putrefaction. Inmates, except one man who was strangled, died as a consequence of the disease. During all autopsies, special attention was paid to the high rate of extrapulmonary Mycobacterial infections. Suicides were committed in different ways and the majority of the victims were documented to be still in the initial stages of the disease. Suspicious deaths and deteriorated corpses were the result of negligence of the subject's families. Homicidal deaths occurred in subjects in the terminal stages of the disease inside the hospital where these subjects were assisted and the immunodeficiency certainly contributed to aggravate the injuries leading to death. Attention is drawn to both legal and social issues affecting AIDS victims. The authors believe these issues may pose a hindrance for efficient control of the AIDS epidemic.

Epidemiologic studies among Amerindian populations of Amazonia. II. Prepvalence of Mansonella ozzardi.

The prevalence of microfilaremia among Indians in 13 Amazon Indian villages was determined by examining Giemsa-stained peripheral blood smears and preparations from peripheral blood lymphocyte cultures. Mansonella ozzardi was the only species found in the 601 persons tested. Prevalence was highly village-specific, ranging from 0% in four villages to as high as 93% among persons aged 10 years and older in others. Comparisons of the two methods showed that the concentration effect of the peripheral blood lymphocyte culture preparations allowed the detection of a greater number of microfilaria-positive persons, especially women and children with lower levels of parasitemia.
