Detection of anti-Giardia lamblia serum antibody among children of day care centers

OBJETIVOS: Detectar anticorpos séricos anti-Giardia lamblia entre crianças atendidas em creches e estimar a freqüência de infecção por Giardia lamblia em área endêmica. MÉTODOS: Foram coletadas três amostras de fezes de cada uma das 147 crianças de três creches da rede municipal de Botucatu, SP, com idade variando de 0 a 6 anos, e as amostras foram processadas pelos métodos de sedimentação espontânea e flutuação pelo sulfato de zinco. Amostras de sangue foram obtidas da polpa digital, coletadas em papel de filtro e testadas pelos métodos de imunofluorescência indireta (IFI) e de reação imunoenzimática (Elisa) para pesquisa de IgG anti-Giardia. RESULTADOS E CONCLUSÕES: de um total de 147 crianças, 93 (63,3%) apresentaram cistos de Giardia nas fezes. Dos 147 eluatos testados, 93 (63,3%) e 100 (68%) foram positivos para Giardia em IFI e em Elisa, respectivamente. A sensibilidade de IFI foi de 82% e de Elisa, 72%. Contudo, Elisa foi menos específica (39%) do que IFI (70%). A imunofluorescência indireta apresentou maior concordância com o exame de fezes do que Elisa.

Potential anticariogênico de soluções aciduladas com baixa concentração flúor

Objetives: The aim of this study was to verify the anticariogenic effect of acidulate solutions with low NaF concentration, using pH-cycling model and bovine enamel. Material and methods: Enamel blocks were submitted to the surface microhardness (SMH) test and randomly divided in 12 experimental and one placebo groups. The blocks were submitted to pH cycling for 7 days, with daily applications once/day of 0.05% NaF and 0.1% NaF and twice/day of 0.02% NaF solutions. Four different pH: 4.0. 5.0, 6.0 and 7.0 were used. Next, SMH test was again used to determine the surface microhardness percentage change (%SMH). Data obtained for %SMH were homogeneous and passed through variance analyses and Tukey's test (5%) as far as fluoride concentrations and pH. Resulls:The results showed that pH influenced %SMH in 0.02% NaF and 0.05% NaF solutions with pH 4.0, which had less mineral loss compared to pH 7.0 (p̃0.05). The 0.02% NaF - pH 4.0, and 0.05% NaF- pH 7.0 groups showed similar results (p>0.05). A dose-response relationship was observed among the tested solutions, with better anticariogenic effect for the 0.1% NaF solution. Conclusion: The results suggest that the addition of citric acid to acidulate mouth rinses reduce mineral loss.

Aquisição da linguagem: as crianças e sua atitude responsiva a perguntas abertas

Introduction: Since their first month of life, babies already show alternation in their communication, in which adults have an important role, assuming interaction turns with the child through questions known as eliciting questions. Verifying this alternation incited us to analyze children’s responsive attitudes toward the questions of the adult interlocutor. Objetives: (1) describe and characterize the kinds of responsive attitudes children have to open questions; (2) verify if there are any differences between the developed and non-developed kinds in the answers. Material and method: data were extracted from 28 interviews (recorded both in audio and in video) with four male children (5-6 years-old) who attended a public Kindergarten. Results: regarding the first objective, 88.7% of the attitudes were answers to the questions, 4.7% were non-responses and 6.6% were confirmation requests. Regarding the second objective, 48.2% of the answers were developed and 51.3%, non-developed. Conclusion: Although the high percentage of answers indicates that the children showed themselves sensitive to the demands of the adult interlocutor, the small percentage difference between developed and non-developed answers also indicates that children mostly depend on their assistance to develop their utterance since they oscillate between restricting themselves to the demand of the interlocutor and expanding it.

Sistema de gestão ambiental: subsídios para a implantação em uma estação de tratamento de esgoto a partir da análise crítica de estudos ambientais prévios

The process of environmental impact assessment (EIA), in the extent of previous environmental studies, has as one of its functions to provide subsidies to the actions of environmental managment of enterprises. However, the proper estructuring of programs that allows to support this managment does not often occurs. This research sought as one of its objectives to evaluate in which extent the process of EIA can be a subsidie for the EMS, providing basic elements of this system. In addition, more specifically, the research had as one of its objetives the development of subsidies for the implantation of an Environmental Managment System (EMS), based on the model of ISO 14001 (2004), for a sewage treatment plant yet to be constructed in the city of President Venceslau / SP. In order to achieve theses objetives, a discussion was held based on the evaluation of environmental studies available in the library of Cetesb / SMA. Still, for the elaboration of subsidies for the EMS of the treatment plant, the research was focused on the structuring of environmental management program, based on the information contained in its Preliminary Environmental Report (PER). The research had as one of its products, the development of subsidies for the planning and control of the environmental aspects and impacts and for the environmental program of the enterprise, based on the use of environmental indicators. It was concluded, based on the results that, in general, the previous environmental studies analyzed showed little emphasis on the phase of development of structured environmental programs that offer guidelines to achieve the desired results for the environmental performance of the company.

As contribuições da Pedagogia Waldorf no atendimento a diversidade e na valorização das diferenças

The ideal of Waldorf Education, since the opening of the first school in 1919, was based on innovative principles for a humanized society. Among those principles, there was the attendance of all children without distinction, which is exactly the main idea of the inclusive school. Waldorf pedagogy defends that under the right pedagogical action and care with the individual development, anyone can develop, regardless of their disability. This statem ent highlights the main objective of this methodology, that is the human development, aligned to another fundamental guideline of inclusive education. Accordingly, the hypothesis of this work is that Waldorf education promotes inclusive schooling contexts, attending diversity and valuing differences. The general objective of this study is: analyze Waldorf Education to verify if it promotes inclusive contexts. And the specific objetives were: identify elements in this practice that favors diversity attend; analyze the practice of a Waldorf school, considering documentation, structure, and conception of managers, teachers and parents. The study was based on quantitative and qualitative research approach, and the data was collected trough observation of teaching practices in a classroom where a disabled student was present, as well as through documentation and observation of the school environment. Furthermore, in order to verify the understanding of parents (71 individuals) and teachers (18 individuals) on inclusion, a specific questionnaire was developed for each of these two groups. For the records, a diary and an observation script were used. It was concluded that Waldorf methodology provides all the necessary conditions to inclusion, mainly due to it's enhancement of individuality, didactic organization and it's roots in social relations
