OBJETIVO: Comparar taxas de internações por condições sensíveis em municípios-sede de coordenadorias de saúde. MÉTODOS: Estudo ecológico com indivíduos de ambos os sexos de 20 a 59 anos nos municípios-sede das coordenadorias regionais de saúde do Rio Grande do Sul de 1995 a 2007. Os dados sobre internações foram obtidos do Datasus. Foram analisadas as taxas mediante regressão de Poisson com variação robusta. As taxas dos municípios foram comparadas com as do restante do estado do Rio Grande do Sul, excluídos os municípios-sede. RESULTADOS: Os municípios, exceto Porto Alegre (1,01) e Osório (1,02), apresentaram redução das taxas de internações por condições sensíveis. Entre os municípios grandes, as maiores quedas foram observadas em Santa Maria (0,92) e Pelotas (0,93). Os municípios médios apresentaram taxas inferiores no final do período. Nos pequenos, apenas Lajeado e Frederico Westphalen apresentaram taxas inferiores às do estado em 2007. As maiores taxas foram observadas nos municípios pequenos. CONCLUSÕES: Houve tendência de diminuição das internações em quase todos os municípios, possivelmente pela ampliação da atenção primária antes mesmo do Programa Saúde da Família e das modificações de gestão. As elevadas taxas de hospitalizações em municípios pequenos sugerem ocupação de leitos por condições sensíveis para justificar oferta ociosa.

The unexpected discovery of a small outcrop of igneous rock isolated within an extensive outcrop of Neogene and Quaternary sediments called for the attention of CEPUNL's researchers. The rock is a dacite whose Rb-Sr age (C. A. and M. H. C.) is 291 M. y. upper Carboniferous. Hence the dacite may be related to volcanism in the Santa Suzana tectonic basin.

In order to evaluate the distribution of dermatophytes in Porto Alegre, the capital of the state of Rio Grande do Sul, Brazil, they were isolated from the skin, hairs and nails samples and retrospectively analyzed from June 1981 to June 1995, in two different institutions in the city of Porto Alegre: (i) the Serviço de Micologia do Instituto de Pesquisas Biológicas Jandyr Maya Faillace, da Secretaria de Saúde e Meio Ambiente do Rio Grande do Sul which attends the low income population (low and middle classes) and, (ii) Laboratório Weinmann, a clinical pathology laboratory which attends predominantly the higher income population (middle and upper classes), both which attend in the metropolitan area of Porto Alegre. The dermatophyte predominance of Trichophyton rubrum was confirmed (55.33%) followed by T. mentagrophytes (21.46%). The data obtained were compared with the existing prevalence data which were collected in the interior of the state over a period of 32 years (1960-1992). T. verrucosum, T. simii, Microsporum persicolor, T. schöenleinii, M. nanum and M. cookei were isolated in the interior and have not been found in the capital so far. On the other side, T. violaceum was, isolated in the capital and has not been found in the interior so far.

Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5%). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.

Parasitic infections caused by intestinal protozoan and helminths affect more than two billion people worldwide and chemotherapy is the most commonly used therapeutic procedure. Considering the problems created by parasitic infections and the incorrect use of drugs, the aim of this work was to detect the frequency of enteroparasites infection and to estimate the use of chemotherapeutic agents in children living in the periphery of the city of Porto Alegre, RS, Brazil. Ninety-six preschool age children, who had parasitological exams and who used antiparasitic drugs, were analyzed. The efficacy of treatment was evaluated by stool examination repeated six months after treatment. The same diagnostic test was used to evaluate parasitological cure, which was defined as absence of eggs and cysts in the stool. From these children, 79 (82.3%) were contaminated by some species of parasite, the most prevalent were Ascaris lumbricoides, Trichuris trichiura and Giardia lamblia. The most commonly used drugs were mebendazole (86% of prescriptions) and metronidazole (30.3%). The cure rate in the 79 children, examined 6 months after treatment, was 65.3% for A. lumbricoides and 66.1% for T. trichiura. This study suggests that a continuous education program regarding the prevention and treatment of parasitic infections is an essential tool for their eradication.

In South Brazil the circulation of two HIV-1 subtypes with different characteristics represents an important scenario for the study of the impact of HIV-1 diversity on the evolution of the HIV-1 epidemic and AIDS disease. HIV-1 B, the predominant variant in industrialized countries and HIV-1 C, the most prevalent subtype in areas with rapid epidemic growth, are implicated in most infections. We evaluated blood samples from 128 antiretroviral (ARV) naïve patients recruited at entry to the largest HIV outpatient service in Porto Alegre. Based on partial pol region sequencing, HIV-1 C was observed in 29%, HIV-1 B in 22.6% and, the recently identified CRF31_BC, in 23.4% of 128 volunteers. Other variants were HIV-1 F in 10% and other mosaics in 5.5%. In order to evaluate the association of socio-behavioral characteristics and HIV-1 subtypes, interviews and laboratory evaluation were performed at entry. Our data suggest an established epidemic of the three major variants, without any evidence of partitioning in either of the subgroups analyzed. However, anal sex practices were associated with subtype B, which could indicate a greater transmissibility of non-B variants by vaginal intercourse. This study provides baseline information for epidemiologic surveillance of the changes of the molecular characteristics of HIV-1 epidemics in this region.

The identification of the fungal species belonging to the healthy microflora in animals is a precondition for the recognition of pathological processes causing them. The aim of this study was to investigate the presence of potentially pathogenic fungi in the feces of wild birds collected in Screening Centers. Samples were collected from the feces of 50 cages with different species of birds. The samples were processed according to the modified method STAIB and the plates incubated at 32 °C for up to ten days with daily observation for detection of fungal growth. The isolation of the following species was observed: Malassezia pachydermatis, Candida albicans, C. famata, C. guilliermondii, C. sphaerica, C. globosa, C. catenulata, C. ciferri, C. intermedia, Cryptococcus laurentii, Trichosporon asahii, Geotrichum klebahnii, Aspergillus spp., A. niger and Penicillium spp. Knowing the character of some opportunistic fungi is important in identifying them, facilitating the adoption of preventive measures, such as proper cleaning of cages, since the accumulation of excreta may indicate a risk for both health professionals and centers for screening public health.

De um total de 545 amostras de sangue, colhidas ao acaso entre a população rural do município de São Lourenço do Sul (RS) e submetidas a reação de fixação de complemento, 21 reagiram positivamente para a Doença de Chagas (3,85%). Não houve diferença significativa com relação ao sexo, cor ou etnia, dos examinados. Os índices de prevalência mostraram-se mais elevados nas zonas periféricas do município, contíguas as áreas endêmicas dos municípios vizinhos. A análise dos eletrocardiogramas revelou 57,4% de alterações nos positivos contra 26,72% nos negativos com diferença estatisticamente significativa a favor dos positivos. A medida de tensão arterial mostrou que entre 442 pessoas acima dos 18 anos, 154 (34,84%) apresentaram valores tensionais aumentados, sem diferença significativa entre os sexos ou os grupos étnicos.

Ratos inoculados previamente com a cepa Y do Trypanosoma cruzi (n = 15) e ratos-controles de mesma idade e sexo (n = 15) foram submetidos a estudo que consistiu no exame da mucosa gástrica após a exposição in vivo da mesma à solução acidificada de um sal biliar, o taurocolato de sódio (TC). Em 10 animais de cada grupo procedeu-se também à contagem dos neurônios do plexo mientérico do estômago e ao exame histopatológico dos corpos neuronais, feito em microscopia óptica convencional. Escores indicativos da gravidade das lesões produzidas pelo TC foram significativamente maiores (P < 0,002) nos ratos chagásicos que nos controles. A área erosada da mucosa gástrica, em % da área total da região glandular do estômago, foi significativamente maior (P0,10) entre os ratos chagásicos (1683,6 ± 449,7 n = 10) e os controles (1732,8 ± 401,1 n = 10). Não houve diferença qualitativa ao exame histopatológico dos corpos neuronais. Estes resultados indicam que, na doença de Chagas experimental crônica, a mucosa gástrica é mais sensível à ação lesiva do TC, o que sugere redução da citoproteção natural do estômago. Esta anormalidade não deve decorrer de alterações da inervação intrínseca que impliquem redução do número de neurônios intramurais do estômago, mas pode ser o resultado de alterações qualitativas não detectáveis à microscopia óptica.
