[We control our bodies: the biological and social dialectic].
This article aims at reviewing the discussion of biological and social factors in the analysis of women's social condition. With the appearance of a feminist perspective, the dominance of earlier biologically-based explanations was substituted by an emphasis on the social construction of female identity. Even when women's identification with the body and with nature, and their secondary status, were considered universal, biological determinism was rejected. In this process of re-definition of the object of study, the ideological role of science was pointed out, since male dominance in science and society accompanied the historical tendency which relegated "the woman question" to the sphere of natural fact. Although growing awareness of the socially-constructed nature of scientific activity itself is producing a tendency to abandon the biological/social dichotomy at the conceptual level, differences between men and women in the reproductive sphere continue to exist. It is argued that analysis of reproduction requires characterization of the sexes as biosocial entities in relationship, situated in specific historical contexts, and that in modern society women are subject to a double reproductive contradiction.
Differential trends in mortality from AIDS in men and women in Brazil (1984-1995).
OBJECTIVE: To analyse trends in AIDS mortality in men and women in Brazil, for the period 1984-1995. DESIGN AND METHODS: National statistics on yearly numbers of reported deaths by cause, in conjunction with census population counts and inter-censory estimates, were used to calculate age- and sex-specific AIDS mortality rates for Brazil as a whole and for São Paulo and Rio de Janeiro, the two largest cities in Brazil, and those most affected by the AIDS epidemic to date. RESULTS: Numbers of reported deaths from AIDS have increased yearly in Brazil since 1984, to approximately 15,000 in 1995. The data suggest that after a very dramatic rise in mortality rates, the epidemic may have started to slow even before the introduction of freely available highly-active anti-retroviral therapy, although unequally in terms of both geographical and sex distributions. Women also tended to die at relatively younger ages than men in all areas studied, and by 1995 the impact of AIDS on overall mortality was practically the same for men and women aged 25-34 years (21% in São Paulo). CONCLUSIONS: Trends in mortality from AIDS in Brazil reflect both the geographical expansion of the epidemic outwards from its original epicentres, and the fact that women are becoming increasingly affected by the AIDS epidemic.

Providing intraosseous anesthesia with minimal invasion.
A new variation of intraosseous anesthesia--crestal anesthesia--that is rapid, site-specific and minimally invasive is presented. The technique uses alveolar crest nutrient canals for anesthetic delivery without penetrating either bone or periodontal ligament.
