Epidemiological situation of visceral leishmaniasis on the Island of São Luis, State of Maranhão
Apresenta-se o resultado de um estudo de campo sobre a leishmaniose visceral autóctone da Ilha de São Luís. Com início em 2004 e término em 2006, a pesquisa visou conhecer aspectos epidemiológicos e clínicos determinantes da endemia. Foram analisados 299 casos autóctones, sendo 83,6% em menores de 9 anos e 54,1% do sexo masculino. O agravo ocorreu em todos os meses do ano com pico em junho. O coeficiente de incidência foi reduzido de 46,1 para 35,2 casos por 100.000 habitantes nos anos estudados. O diagnóstico teve confirmação laboratorial em 93,3% dos casos. O tratamento de escolha foi à base de N-metilglucamina com percentual de cura de 96,1%. A letalidade média foi de 3,7%. Em função da inexistência de ações mais sistemáticas de controle, propõe-se a criação de um programa a ser desenvolvido pelos municípios sob a coordenação da Secretaria de Estado da Saúde.The results from a field study on autochthonous visceral leishmaniasis on the island of São Luís are presented. This study started in 2004 and finished in 2006 and had the aim of ascertaining the determinant epidemiological and clinical characteristics of this endemic disease. Two hundred ninety nine autochthonous cases were analyzed, of which 83.6% were children younger than 9 years old and 54.1% were male. The disease occurred in all months of the year, with a peak in June. The coefficient of incidence decreased from 46.1 to 35.2 cases per 100,000 inhabitants over the years studied. The diagnosis was confirmed by laboratory tests in 93.3% of the cases. The treatment of choice was based on N-methylglucamine, with a cure rate of 96.1%. The mean lethality rate was 3.7%. Because of the absence of systematic control actions, the authors propose the creation of a specific program to be developed by the municipalities under the coordination of the State Department of Health
Health-related quality of life in patients with type 1 diabetes mellitus in the different geographical regions of Brazil : data from the Brazilian Type 1 Diabetes Study Group
Background: In type 1 diabetes mellitus (T1DM) management, enhancing health-related quality of life (HRQoL) is as important as good metabolic control and prevention of secondary complications. This study aims to evaluate possible regional differences in HRQoL, demographic features and clinical characteristics of patients with T1DM in Brazil, a country of continental proportions, as well as investigate which variables could influence the HRQoL of these individuals and contribute to these regional disparities. Methods: This was a retrospective, cross-sectional, multicenter study performed by the Brazilian Type 1 Diabetes Study Group (BrazDiab1SG), by analyzing EuroQol scores from 3005 participants with T1DM, in 28 public clinics, among all geographical regions of Brazil. Data on demography, economic status, chronic complications, glycemic control and lipid profile were also collected. Results: We have found that the North-Northeast region presents a higher index in the assessment of the overall health status (EQ-VAS) compared to the Southeast (74.6 ± 30 and 70.4 ± 19, respectively; p < 0.05). In addition, North- Northeast presented a lower frequency of self-reported anxiety-depression compared to all regions of the country (North-Northeast: 1.53 ± 0.6; Southeast: 1.65 ± 0.7; South: 1.72 ± 0.7; Midwest: 1.67 ± 0.7; p < 0.05). These findings could not be entirely explained by the HbA1c levels or the other variables examined. Conclusions: Our study points to the existence of additional factors not yet evaluated that could be determinant in the HRQoL of people with T1DM and contribute to these regional disparities

Risk factors for Leishmania chagasi infection in an endemic area in Raposa, State of Maranhão, Brazil Fatores associados à infecção por Leishmania chagasi em uma área endêmica em Raposa, Estado do Maranhão, Brasil
INTRODUCTION: Infection with Leishmania chagasi is the most common clinical presentation for visceral leishmaniaisis in endemic areas. The municipality of Raposa is an endemic area in State of Maranhão, Brazil, and have had registration cases of visceral leishmaniasis disease. For this reason, a cross- sectional study was conducted to evaluate the risk factors for infection with L. chagasi detected by Montenegro skin test. METHODS: The sample comprised 96% of the inhabitants of the villages of Maresia, Pantoja, and Marisol located in the municipality of Raposa, corresponding to 1,359 subjects. Data were collected using a questionnaire. Univariate and multivariate logistic regression models were applied to evaluate the association between the variables studied and infection of L. chagasi. RESULTS: The variables associated with infection upon nonadjusted analysis were a straw roof, mud walls, floors of beaten earth, presence of sand flies inside or outside of the dwelling, and bathing outdoors. Adjusted analysis showed that the presence of sand flies inside/outside the dwelling was a risk factor, and age younger than 10 years was a protective factor against asymptomatic infection. CONCLUSIONS: The results highlight the extent to which precarious living conditions of the population strengthen the epidemiological chain of visceral leishmaniasis.<br>INTRODUÇÃO: A infecção por Leishmania chagasi é a apresentação clínica mais comum de laishmaniose visceral em áreas endêmicas. O município de Raposa é área endêmica no Estado do Maranhão, tendo registrado casos da doença. Por isso, realizou-se um estudo transversal, com o objetivo de estudar os fatores de risco para infecção por L. chagasi detectada pelo teste intradérmico de Montenegro. MÉTODOS: O estudo envolveu 96% dos moradores das localidades de Maresia, Pantoja e Marisol do município da Raposa, totalizando 1.359 indivíduos. O levantamento dos dados foi realizado utilizando um questionário. Para verificar a associação entre as variáveis estudadas e a infecção por L. chagasi, foram utilizados os modelos de regressão logística uni e multivariada. RESULTADOS: Na análise não ajustada, as variáveis associadas à infecção foram: cobertura da casa de palha, paredes de taipa, piso de chão batido, a presença de flebotomíneos dentro ou fora do domicílio e o local do banho fora de casa. Na análise ajustada, a presença de flebotomíneos dentro ou fora do domicílio foi considerada fator de risco e a idade menor que 10 anos revelou-se como fator de proteção para a infecção assintomática. CONCLUSÕES: Evidenciou-se também, o quanto a precariedade das condições de vida da população contribui para o fortalecimento da cadeia epidemiológica da doença
