Transformation and trends in preventive and social medicine education at the undergraduate level in a Brazilian medical school.

In the present study we discuss some transformations in undergraduate training in Preventive and Social Medicine in the Department of Social Medicine of the Faculty of Medicine of Ribeiro Preto, University of So Paulo, from 1993 to 1999. Aspects of the relationship between medical training and the reorganization of local services of the Brazilian national health system, and between graduate teaching in Preventive and Social Medicine and medical education as a whole are discussed. The crisis in Preventive and Social Medicine and its influence of medical training are evaluated. Trends for the application of a body of knowledge of the specialty and for the relationship between the department and the medical school are discussed.

A case of human rabies in the urban area of Ribeirã Preto, SP, Brazil.

A 39-year old male patient was admitted to the University Hospital of the Faculty of Medicine of Ribeirão, Preto with signs and symptoms of sudden dyspnea, generalized myalgia and behavioral disorders. The initial suspicion was alcohol abstinence syndrome and the patient was referred for psychiatric and neurologic care. The evolution of the patient with a worsening of signs and symptoms, presence of crises of tachypnea, agitation, difficulty to swallow, irritability and hydrophobia, and his report of having been bitten by a suspected dog raised the hypothesis of rabies. The diagnosis was confirmed by examination of a corneal impression, biological tests in the cerebrospinal fluid (CSF) and saliva and visualization of Negri bodies in nervous tissue (direct immunofluorescence). The patient evolved with agitation, aggressiveness, and worsening tachypnea intercalating with apnea, and died on the 4th day after admission.

[Serological markers of hepatitis B in users of services at an HIV Testing Center].

The objective of this investigation was to study the prevalence of serological markers of hepatitis B and possible risk factors for this disease in a sample of 404 people who attended a Testing and Couseling Center for HIV in the city of Ribeirão Preto, São Paulo State, Brazil. The overall prevalence of serologic hepatitis B markers was 14.6%, equal to that obtained for anti-HBc. HBsAg and anti-HBc IgM showed prevalences of 1%. After adjustment using logistic regression, hepatitis B markers showed association with the following variables: age, place of residence, use of injectable drugs and positivity to anti-HIV. The overall prevalence of human immunodeficiency virus infection was 6.9%. Hepatitis B markers were detected in 55.6% among intravenous drug users and in 42.9% among those who tested positive for HIV, confirming literature findings which indicates high levels of infection in these specific population groups.

[Survival and infectious processes in pacients with AIDS: analysis based on initial serum vitamin A levels].

Patients with Aids (n = 39) were followed up for a maximum period of 36 weeks, after which the types and topographies of infectious complications presented and patient survival were analyzed and correlated with the vitamin A levels presented by the patients at the beginning of clinical follow-up. Twenty-one (53,8%) patients presented serum retinol levels below 1.6 micromol/L, 12 (57%) of whom had values lower than 1.05 micromol/L. There was no correlation between low serum vitamin A levels and the types or topographies of the infectious complications that occurred during the follow-up period. Although mean survival at the end of the 36 months follow-up period was similar for the two groups, patients with retinol deficiency presented a lower probability of survival during the first 24 months of follow-up compared to patients without hypovitaminosis A (8.44 x 1.42 months; p = 0.003).

[Rabies epizootic in the urban area of Ribeirão Preto, São Paulo, Brazil].

This report describes some epidemiological aspects of a rabies epizootic that started in 1995 in the urban area of Ribeirão Preto, SP, Brazil, and discusses its main causes. All laboratory confirmed cases were described according to a set of epidemiological variables. Simultaneously, information was raised concerning rabies vaccine coverage and epidemiological surveillance activities. In addition to one human case, 58 rabid animals were confirmed in 1995 (54 dogs, 3 cats. and 1 bat). There were 20 cases in 1996 (18 dogs and 2 cats). Geographical distribution was uneven in the city, with higher concentrations observed in the Western, Northern, and Southwestern sections, corresponding to the poorest areas. No seasonal variation was observed. The main reasons for the epizootic were low rabies vaccine coverage in animals and severe failures in epidemiological surveillance activities in the years immediately prior to 1995. This epizootic illustrates the risk of neglecting such activities, even in a city with a reasonably good health system, located in one of the most economically developed areas of the country. Vigorous preventive measures markedly reduced the number of cases.
