Abstract: objectives: to identify initial predictive factors of renal involvement in children and adolescents with henoch-sch?nlein purpura. methods: we reviewed the medical records of 142 patients admitted to our university hospital over a 21-year period with a diagnosis of henoch-sch?nlein purpura. the initial predictive factors assessed, observed during the first 3 months, included: demographic data, clinical manifestations (persistent palpable purpura, arthritis, abdominal pain, severe abdominal pain, gastrointestinal bleeding, orchitis, central nervous system involvement and pulmonary hemorrhage), laboratory tests (serum iga levels) and treatment given (corticosteroids, intravenous immunoglobulin and immunosuppressive drugs). patients were divided into two groups (presence or absence of nephritis) and assessed by univariate and multivariate analysis. results: evidence of nephritis was detected in 70 patients (49.3%). the univariate analysis revealed that severe abdominal pain (p = 0.0049; or = 1.6; 95%ci 1.18-2.21), gastrointestinal bleeding (p = 0.004; or = 1.6; 95%ci 1.10-2.26) and corticosteroid use (p = 0.0012; or = 1.7; 95%ci 1.28-2.40) were all associated with increased incidence of renal involvement. in the multivariate analysis, logistic regression demonstrated that the only independent variable that predicted nephritis was intense abdominal pain (p < 0.012; or = 2.593; 95%ci 1.234-5.452). conclusions: severe abdominal pain was a significant predictor of nephritis in henoch-sch?nlein purpura. consequently, pediatric patients exhibiting this clinical manifestation should be rigorously monitored, due to the increased risk of renal involvement.

Abstract: objective: to estimate the degree of internal exposure to organochlorine pesticides (persistent organic pollutants, pop) among inhabitants of an open-air dump. methods: this was an observational study with simultaneous measurement and control, in which the criterion for subjects was that they dwelled in an area contaminated by pop and the effect of such contamination was the concentration of such substances into the blood. the study population consisted of 238 people living on an open-air dump in pil?es, in the municipality of cubat?o, sp, brazil, and the control population was formed by 258 people, also resident in that municipality, in the cota 200 district. the following pesticides were analysed: hexachlorobenzene (hcb), p-p'ddt, p-p'dde, p-p'ddd, o-p'ddt, a hch (hexachlorocyclohexane); b hch; g hch; aldrin; dieldrin; endrin; heptachlor; heptachlor-epoxy and mirex. results: the average blood level of hcb in pil?es was 4.66 μg/l, which was 155 times higher than the average for cota 200 (0.03 μg/l). in pil?es the average blood concentration of total ddt was 3.71 μg/l, which was twice the level found in cota 200 (1.85 μg/l). total hch presented blood concentrations that were six times greater in pil?es (0.84 μg/l versus 0.13 μg/l). conclusions: a positive association was shown between dwelling in pil?es and the presence of pop in the blood, with much higher risks than in localities without the presence of these contaminants.

Abstract: objetive: the purpose of the study was to discuss bodily changes perceived by pregnant adolescent girls and their opinion in regard to such changes. methods: data was collected through interviews based on questionnaires and applied to 132 pregnant teenagers in three different public institutions in goiania from 1996 to 1997. a family support scale was also applied and another attitude in relation to weight gain. results: pregnant teenagers were, in average, 16 years old, 64% of them were married and 78% were not studying. data from the family support scale has indicated positive support to the pregnant women. the chief bodily changes observed were in the breasts, weight, and in the abdomen or belly. the most desirable change involved the growth of the belly, perhaps on account of the role maternity plays in society; and the least desirable ones were the augmented breasts. a statistically significant deviation (p<0.05) was found regarding the gap between the weight evaluation prior to pregnancy and the weight gained, once that 92 percent expressed positive attitudes in regard to weight gain. conclusion: proper health-center guidance during prenatal care should range from the interaction between the pregnant teenager and the universe where she lives and assistance in the perception of changes her body is undergoing.

Abstract: O processo de recupera o do solo de uma área degradada deve ter como princípio básico o retorno de condi es mínimas para o estabelecimento e crescimento das plantas. O presente trabalho teve por objetivo avaliar o desenvolvimento e estabelecimento de algumas espécies arbóreas exóticas e nativas submetidas a diferentes doses de corretivo numa área degradada com intensos processos erosivos no município de Uberlandia - Minas Gerais. O período experimental foi conduzido de fevereiro a maio de 2009, numa área rural de cascalheira em avan ado estado de degrada o. Avaliaram-se oito espécies, quatro delas exóticas (Acacia mangium, Gliricidia sepium, Mimosa artemisiana e Acacia auriculiforme) e quatro nativas (Gon alo Alves - Astronium fraxinifolium; Mutamba – Guazuma ulmifolia; Angico vermelho - Anadenanthera macrocarpa; e Ingá - Inga edulis). O desempenho de cada espécie foi submetido a quatro diferentes doses de calcário (0, 50, 100 e 200 g de CaCO3), resultando em 32 tratamentos com duas repeti es, sob delineamento experimental inteiramente casualizado. As variáveis estudadas - diametro do caule, largura da copa e altura da planta aos 60 dias do plantio – foram submetidas a análise de variancia e comparadas pelo teste de Scott - Knott a 5% de probabilidade. No período de estudo, as doses de calcário avaliadas n o produziram diferen as significativas. Em contra partida, houve varia o de desenvolvimento entre espécies para todas as variáveis analisadas. G. sepium apresentou melhor estabelecimento e crescimento inicial em diametro, seguida de I. edulis e G. ulmifolia. Quanto à altura final da planta, destacaram-se as nativas Ingá, Angico vermelho e Mutamba, bem como as exóticas G. sepium, A. auriculiforme e A. mangium, mostrando-se cómo potencialmente aptas para serem utilizadas na sucess o ecológica de áreas degradadas no Cerrado.

Boletim da Sociedade Paranaense de Matemática , 2003,
Abstract: Let α be a real vector bundle of ber dimension three over the product RP(m)×RP(n) which splits as a Whitney sum of line bundles. We show that the necessary and su cient conditions for α to embed as a sub-bundle of a certain family of vector bundles β of ber dimension m+n is the vanishing of the last three Stiefel-Whitney classes of the virtual bundle0 β α. Among the target bundles β we consider the tangent bundle.
Health promotion: Criticism of everyday life medicalization practices
Kênia Silva,Roseni Sena
Journal of Nursing Education and Practice , 2013, DOI: 10.5430/jnep.v3n9p83
Abstract: The aim of this study was to analyze the meanings of the practices of health promotion. The results indicate that the practices in different social areas are sustained within the mechanisms of social control and management of vulnerable populations. Thus, there is the feedback of the biomedical paradigm now materialized in different practices in different areas beyond the traditional health services. It is concluded that health promotion in areas of daily life presents the challenge of expanding the potential autonomy of action of individuals in movements that consider the potential social areas in constant transformation of everyday life.

Abstract: the present study aimed to evaluate the incorporation of the immunofluorescence test (ift) with adult parasite paraffin sections as antigen substrate for the detection of igm antibodies (igm-ift), as a diagnostic method in the schistosomiasis control program in the county (municipality) of holambra, s?o paulo state, brazil. this city was selected for this study based on its low endemicity for schistosomiasis, the first cases having been reported in 1993, and because of the need to implement a control program with more sensitive diagnostic techniques. 202 individuals underwent igm-ift, with 48 serologically positive cases; of these, 28 were tested with the kato-katz technique, using three stool samples. schistosoma mansoni eggs were found in 14 individuals, with egg counts varying from 2.7 to 224 per gram of stool. the results indicate the potential usefulness of igm-ift as a screening test, subject to subsequent confirmation using a parasitological method, in low-endemic areas for schistosomiasis.

Kanamura, Hermínia Y.;Hoshino-Shimizu, Sumie;Lima, Dirce M. C.;Abrantes, Clarice P.;Silva, Luiz Caetano da;
Memórias do Instituto Oswaldo Cruz , 1987, DOI: 10.1590/S0074-02761987000800038
Abstract: the recent findings on immunodiagnosis of schistosomiasis mansoni have shown that purified schistosoma mansoni antigens do not provide maximum positivity. therefore, the authors suggest the use of semi-purified antigens for diagnostic purposes. so far, no serological marker for cured patients as shown by negative stool examination was found. however, a tendency of igg antibody titre decrease was observed, when egg antigen was used.

Abstract: differences among plants in their ability to support nutritional stress periods may be caused by a differential vacuole capacity of ion storage and release and may also depend on the intensity of nutrient re-translocation under such conditions. in five soybean cultivars, submitted to eight days of p deprivation, the dry matter production and the contents of three phosphorus (p) forms - inorganic (pi), organic (po), and acid-soluble total (pts) of different plant organs were determined. pi release velocity (rspi) was estimated as the tangent to the equations obtained for pi f(t) at the point t = 2 days (the mean point in the period of greatest pi decrease), considering that -dpi/dt expresses the rate of pi release. the internal pi buffering capacity (ibcpi) was calculated as the inverse of the rspi. cultivars' differences in size of the non-metabolic pi pool, rspi, and the ability to transport pi from less to more actively metabolizing regions were evaluated. the preferential pi source and sink compartments under limited p absorption conditions were also evaluated. the cultivar santa rosa showed the highest pi storage ability when the external supply was high, and a more intensive release under low p supply conditions than iac8 and ufv1. the cultivar uberaba was superior to doko in its ability to store and use pi. in all cultivars, upper leaves and roots were the main sink of pi stored in the middle and lower leaves. roots and upper leaves showed larger rspi and lower ibcpi values than middle and lower leaves.
