Ação farmacológica de Syzygium cumini (L.) skeels

Natural products have received new interest recently, maybe in men's attempt to turn into the nature for the prevention and the relief of diseases, mainly because of those untreated by the traditional medicine. Syzygium cumini (L.) Skeels, popularly known as 'jambolão, is a well-known plant by several pharmacological actions so much in the popular use as in the scientific literature. In this search antidiabetic, anti-diarrhoeal, anti-inflammatory, antioxidant and antimicrobial activities of 'jambolão' were described, among other actions.

Occurrence of Actinobacillus actinomycetemcomitans in patients with chronic periodontitis, aggressive periodontitis, healthy subjects and children with gingivitis in two cities of the state of São Paulo, Brazil

The aim of this study was to determine the frequency of isolation of Actinobacillus actinomycetemcomitans (Aa) in 100 patients with chronic periodontitis, 14 patients with aggressive periodontitis, 142 pre-school children with gingivitis and 134 periodontally healthy subjects. Samples of subgingival plaque were taken using sterilized paper points introduced into periodontal pockets or gingival crevice for 60 seconds and inoculated on TSBV agar, which was incubated under anaerobiosis at 37°C, for 4 days. Microbial identification was performed through biochemical methods and morphocellular and morphocolonial analysis. Aa was detected in 40.3% of healthy subjects, 68% of patients with chronic periodontitis, 92.86% of patients with aggressive periodontitis and 40.14% of children with gingivitis. The rate of recovery of Aa in the tested human groups proved to be higher than previously reported and in agreement with participation of this facultative anaerobe as a member of native microbiota of the periodontium and its relation with aggressive and chronic periodontitis in Brazil.

Dynamics of change of mathematics education in Brazil and a scenario of current research

Mathematics education in Brazil, if we consider what one may call the scientific phase, is about 30 years old. The papers for this special issue focus mainly on this period. During these years, many trends have emerged in mathematics education to address the complex problems facing Brazilian society. However, most Brazilian mathematics educators feel that the separation of research into trends is a theoretical idealization that does not respond to the dynamics of the problems we face. We raise the conjecture that the complexity of Brazilian society, where pockets of wealth coexist with the most shocking poverty, has contributed to the adoption and generation of different strands in mathematics education, crossing the boundaries between trends. At a more micro level, we also raise the conjecture that Brazilian trends in research are interwoven because of the way that Brazilian mathematics educators have experienced the process of globalization over these 30 years. This tapestry of trends is a predominant characteristic of mathematics education in Brazil. © FIZ Karlsruhe 2009.

Associação entre condição periodontal de gestantes e variáveis maternas e de assistência à saúde

Objective: To evaluate the periodontal condition of pregnant women and to analyze the influence of maternal variables - socioeconomic-demographic data, health, deleterious habits and access to dental service - and the existence of the Family Health Program (FHP) at the public assistance services to pregnant women. Method: This evaluation was part of a cohort study with pregnant women and children conducted in two cities of the São Paulo State, one of which with an implemented FHP. Oral examinations were done using the Community Periodontal and Periodontal Attachment Loss Indexes, and semi-structured interviews with the pregnant women at their homes. Data were analyzed statistically by the chi-square test and Fisher's exact test at 5% significance level (α=0.05). Results: All pregnant women (n=119) registered at the public health service of each city were examined. The mean age was 24.7 years; 61.4% were black or black/white mixed-race women; most (65.5%) earned 2-3 minimum wages, and only 6.7% initiated higher education. Only 8% of the patients presented periodontal health. Bleeding and calculus were observed in 66% of them, and shallow and deep periodontal pockets in 20%. Periodontal attachment loss > 4 mm was observed in 24% of the pregnant women. The group was homogeneous as to the maternal characteristics, age (p=0.0384) and smoking (p=0.0102) being the only factors associated with periodontal disease. The existence of a FHP at the public assistance service was not associated with a lower prevalence of the disease. Conclusion: The findings of this study show a high prevalence of periodontal alterations during pregnancy, with no influence from the existence of a FHP on the observed conditions. Among the risk variables, age and smoking were the factors associated with the presence of periodontal disease. There is a need for a better planing and accomplishment of oral health actions during the prenatal period.

Employing knowledge networks as tools for the development of Caribbean Small Island Developing States

Expertise, skills, experiences, understandings and capabilities (knowledge) aid development, not just by informing decision-making, but also by providing ideas for actions and activities that can be taken. Due to their size, and economic and environmental vulnerabilities, Caribbean Small Island developing States (SIDS) faces special challenges when working towards their economic, social and environmental development goals. These challenges have contributed to the creation of knowledge gaps, and that which is already available is located in isolated pockets, throughout the Caribbean. Migration of skilled persons compounds the issue, thereby removing much needed knowledge to beyond the traditional borders of the Caribbean. It is necessary to find ways to connect these dispersed knowledge resources. Knowledge networks are tools that can connect the existing skills, expertise, experiences and understandings accessible and create new ones to move towards greater development in the Caribbean. The purpose of this paper is to explore and highlight the role that knowledge networks can play as an aid in the development of Caribbean SIDS. It offers, with Caribbean examples, definitions and discussions of the components, types, and the advantages and disadvantages they hold for the subregion. The paper goes further to provide some ideas on assembling and analysing the different types of knowledge networks. It concludes with a few recommendations geared toward improving the availability of knowledge in the Caribbean.

Condições de saúde bucal de diabéticos acompanhados pelo Programa Saúde da Família em Belém - Pará

Neste estudo foram avaliadas as condições de saúde bucal de diabéticos acompanhados pelo Programa Saúde da Família no município de Belém-Pará. As condições analisadas foram: cárie dentária, doença periodontal, uso e necessidade de prótese dentária e lesões de mucosa. A amostra foi composta de 268 diabéticos e 270 indivíduos não diabéticos compondo o grupo controle. Para a coleta dos dados, foram utilizados os índices recomendados pela Organização Mundial de Saúde. Os exames foram realizados nos domicílios dos indivíduos selecionados por examinadores previamente calibrados. Os dados foram processados no Programa de computação Epi info versão 3.3.2 para o Sistema Operacional Windows e estatisticamente analisados. Os resultados demonstraram que: não houve diferença na prevalência de cárie. O CPOD foi igual a 25,7 e 25,4 para diabéticos e grupo controle, respectivamente, com uma grande perda dentária para ambos os grupos. A presença de cálculo foi verificada em 10,6% dos diabéticos e em 13,6% do grupo controle com a prevalência de bolsa periodontal mais evidente em diabéticos (p<0,05). Aproximadamente metade da amostra necessitava de prótese superior e cerca de 78% dos examinados necessitavam de prótese inferior, não diferindo entre os grupos (p > 0,05). A ocorrência de lesões de mucosa bucal, como estomatites e lesões hiperplásicas, em ambos os grupos, foi relacionada ao uso de prótese dentária inadequada. Os dados encontrados demonstram prevalência significante em todas as condições estudadas em ambos os grupos, mas só a doença periodontal teve relação estatisticamente significante com a condição de Diabetes Mellitus.
