Representações imaginárias atribuídas ao exame do toque retal por homens belemenses

No Brasil, o câncer de próstata é uma doença que representa a segunda causa de morte mais freqüente entre os homens. Na região Norte, esta realidade não é diferente e vem apresentando um ritmo de crescimento acentuado, segundo informações do Instituto Nacional do Câncer - INCA. É um tipo de câncer de evolução lenta e possível de ser detectado e tratado, antes que tome proporções fatais, através de diversos métodos de diagnóstico. Entretanto, um dos maiores desafios no tocante a esta detecção é a mobilização e envolvimento da população masculina em procurar ajuda médica. Isso ocorre, principalmente, porque a prevenção envolve uma possível realização do exame do toque retal. Pensando nisso, este trabalho buscou entender: quais estes impedimentos? Quais os fatores envolvidos para que o homem não cuide de si, especialmente em relação ao câncer de próstata? O objetivo central do trabalho foi investigar: quais as representações imaginárias imputadas ao exame do toque? Em virtude de o foco investigativo ser a apreensão das significações, optou-se pela linha metodológica qualitativa, tendo por referência o Método de Explicitação do Discurso - MEDS. Foram analisadas 10 entrevistas de homens, na faixa etária de 40 a 60 anos. Os seus discursos apontaram que existem barreiras envolvidas neste impedimento, a saber: motivações de ordem estrutural (dificuldade de acesso, carência de informações), mas também barreiras de ordem imaginária, cujos significados tornam o sujeito resistente ao exame e como conseqüência não se previnem, dificultando a detecção de possível doença para posterior tratamento.

Investigação soroepidemiológica para brucelose e leptospirose em equideos de tração e seus tratadores nos municípios de Belém e Ananindeua - Pará

O objetivo do trabalho foi a detecção de anticorpos anti - Brucella abortus e anti – Leptospira interrogans em soros de eqüídeos e seus tratadores nos bairros das cidades de Belém e Ananindeua, abrangendo os meses de abril a agosto de 2005, utilizando para este fim, 195 soros sanguíneos de eqüídeos e 70 soros sanguíneos de homens que manipulavam os animais direta ou indiretamente. Para a pesquisa de animais sororeagentes à B. abortus, foram usadas as provas do Antígeno Acidificado Tamponado (AAT) como teste de triagem e a Soro Aglutinação Lenta em Tubos (SAL) e o teste do 2-Mercaptoetanol (2-ME), como teste confirmatórios. Para a Leptospirose, foi utilizada a prova de Soroaglutinação Microscópica (SAM), sendo realizada a triagem dos soros frente à 25 sorovares de L. interrogans, considerando-se positivos aquelas amostras com titulação igual ou maior que 100. De 195 amostras de soros sanguíneos de eqüídeos, 184 (94,87%) foram positivas para todos os sorovares analisados, sendo que os mais frequentemente encontrados foram: Patoc, Automnalis, Ictehaemohragiae, Pyrogenes e Bratislava. Para as amostras sanguíneas de homens, a positividade foi de 49 (70%) de soros reagentes, com os sorovares Patoc, Ictehaemohragiae, Bratislava, Butembo, Copenhageni e Automnalis os mais detectados. Das amostras positivas de animais e seus respectivos tratadores, 47/70 (67,14%) foram semelhantes para os mesmos sorovares de Leptospira spp., sendo que 2/70 (2,86%) amostras foram negativas em ambos os grupos pesquisados, 2/70 (2,86%) foram somente positivas em homens e 19/70 (27,14%) foram exclusivamente positivas nas amostras de soros de eqüídeos. Os bairros do Coqueiro, Guamá, 40 horas, Barreiro e Bengui apresentaram a maior percentagem de casos soropositivos. Não houve diferença significativa em relação às outras variantes estudadas, como: idade (animal e homem), tempo de serviço (animal e homem), espécie do animal, escore corporal do animal e grau de instrução do homem. Tanto nos animais quanto nos homens não foram detectadas reações positivas para B. abortus.

Metodologia para determinação de volume de detenção em pequenas bacias urbanas: o caso do córrego Wenzel, Rio Claro/SP

With the accelerated urbanization process of Brazil from the 50s, there was a disorderly occupation of spaces and consequent soil sealing. Unlike this growth, the support capacity of urban environments has not evolved in the same way, generating negative environmental impacts to the citizens. Among these impacts are the effects of flooding. In order to minimize the negative effects of extreme precipitation over cities, the government invests in corrective measures, like compensatory techniques on urban drainage, which have as a basic principle the retention and infiltration of the rainfall, dampening the peak flow and runoff. An example of applying these techniques in urban areas are the detention basins, commonly called large pools. The hydraulic design of these structures is dependent of complex data and variables, and projects involving small areas generally use simplified methods for defining the reservoirs volume of the storage (Tassi, 2005). One of these methods is presented in this study, which relates to the percentage of soil sealing to the specific storage volume (m³/ha) in combination by applying the hydrological model of the Rational Method and analyzing regional rainfall and soil occupation over the basin. Within this context, the basin of the Wenzel stream, which is located amidst the urban area of Rio Claro/SP, also presents the problems related to human occupation in its valley. Thus, by the method presented has been adjusted a curve correlating the percentage of impermeable area and the specific volume of a detention basin. For the current situation of Wenzel Basin with 82% of impermeable area, and return period of 10 years, the specific volume is 262.1 m³/ha. The presented method is consistent with the results of other studies in the area, and the expression obtained allows estimating the volume of storage required to match hydrograph pre and post-occupancy. It presents itself as a useful tool in the planning stage of...

Atenolol characterization in solid formulations available in Brazilian market

Atenolol is the most used drug in Brazil to hypertension treatment. Two crystal structures are known for this molecule: a racemic form (R,S)-atenolol and a pure form S-atenolol. The racemic form is found in commercial tablets. X-ray powder diffraction (XRD) is an adequate tool to study crystalline structures including drugs. Using the Rietveld Method with XRD data it is possible to quantify the crystalline structures existing in the raw material. Other methods like Le Bail and Pawley can be used to the profile fit and phases identification. For this work we analyzed three tablets of atenolol, two generics and the reference (materials were purchased from a drugstore at the city of Araraquara). These tablets were analyzed by Rietveld, Le Bail and Pawley methods. All tablets exhibited the racemic mixture API (R,S)-atenolol. Some crystalline excipients could be characterized: magnesium carbonate hydrate, lactose monohydrate and talc. The conclusion is that the three methods can be efficiently used to characterize the three atenolol tablets.

Fundação Casa. a mútua descoberta da realidade do outro

In this paper we present a report of a project developed with young people who were in detention on the CASA Foundation, former FEBEM in Araraquara, in the period in which the activity occurred. Our goal with the project was twofold: that our presence at the Foundation supports the young people in that institution with leisure and social reintegration, and to enable students to make experience of new strategies for teaching undergraduate and citizenship training. The project developed there was entitled "The Art of Storytelling" and, and despite its catchy title, actually had a much less ambitious goal, which was not just enable artists to exercise the storytelling, but chiefly to raise awareness that our worldview and our inner lives are made up by micronarratives, which not only place us in the universe into which we belong and also creates our own identity. Having this perspective as a starting point and following the theoretical assumptions of Paulo Freire, for whom the learning process is interactive and based on the exchange of experiences, we held five meetings and the experience was enriching, both for students and for the Foundation´s youngs that took part in this activity.

Description of a rat palatal acrylic plate that can be relined

Purpose: The objective of this article is to describe a method to construct an intraoralacrylic device that permits a reline material to be added to the inner surface of thepalatal plate.Materials and Methods: Fifteen 60-day-old adult female rats (Rattus NorvegicusAlbinus Wistar), weighing 150 to 250 g were used for this study and allocated to threegroups (n = 5): G1, animals wearing a heat-polymerized acrylic resin palatal plate(Lucitone 550) for 14 days; G2, animals wearing a heat-polymerized acrylic resinpalatal plate (Lucitone 550) relined with Tokuyama Rebase II for 14 days; and G3,animals maintained under the same conditions as the experimental groups, withoutwearing palatal plates for 14 days. The manipulation of the animals followed theguidelines of the Brazilian College of Animal Experimentation, under the approval ofthe animal ethics committee of the State University of Ponta Grossa. The palatal platescovered the whole palate, were fixed in the molar region with light-cured resin, andwere kept there for 14 days. The animals received a paste diet and water ad libitum.Before and after the trial period, the rats were weighed individually on a precisionscale. Statistical analysis was performed using a two-way analysis of variance (α =0.05) test for comparison of the animals’ weight (g) at time 0 and after 14 days ofusing the palatal plate.Results: No statistical differences were observed regarding the weight of the animalsamong the experimental groups in the study.Conclusions: The individual master impressions, the molar teeth coverage, and themethod of cementation with nonadhesive composite resin provided good stability forthe palatal plate showed in this study, not disturbing the eating habits and nutritionof the animals. This model seems reproducible, offering adequate histopathologicalevaluation. Differences in tissue morphology exist between the animals that used thepalatal plate and the animals that did not use this device. Use of these palatal platescould clarify how prostheses bring changes in the palatal mucosa of users.

Effect of post-polymerization heat treatment on a denture base acrylic resin: histopathological analysis in rats

This work examined the histological effects, on the rat palatal mucosa, of a denture base acrylic resin, submitted or not to a post-polymerization heat-treatment. Methods: Fifteen adult female Wistar rats, with sixty days old, weighting 150 g – 250 g were divided in G1: animals being maintained under the same conditions as the experimental groups following described, but without the use acrylic palatal plates (control group); G2: use of heat-polymerized acrylic resin palatal plates made of Lucitone 550; G3: use of palatal plates identical to G2, but subjected to a post-polymerization treatment in a water bath at 55°C for 60 min. The plates covered all the palate and were fixed in the molar region with light-cured resin, thus being kept there for 14 days. After the sacrifice, the palate was removed, fixed in formaldehyde 10% and decalcified with EDTA. Sections were stained using haematoxylin and eosin. Images in duplicate were made from the central region of the cuts, to measure the thickness (μm) of the keratin layers (TKC), epithelium total (TET) and connective tissue (TCC). Statistical analyses were carried out by one-way ANOVA and Tukey post-tests (α=0.05). Results: According to the results there was significant difference in the thickness of keratin between G2 and G3, with G1 having the intermediate value and similar to the other groups. There was a significant difference in the connective tissue with G3
