A hanseníase, doença milenar, ainda constitui um grande desafio para a saúde pública, inclusive no que se refere a diagnóstico precoce e vigilância em saúde. Com objetivo de estimar a soroprevalência de anticorpos antiPGL-1 através do teste rápido ML-Flow em casos de hanseníase e seus contatos intradomiciliares de municípios endêmicos do Pará, realizou-se um estudo transversal incluindo 73 casos novos de hanseníase e 135 contatos intradomiciliares, selecionados no período de abril de 2011 a janeiro de 2012, nas unidades de referência para tratamento de hanseníase nos municípios de Belém, Marituba, Igarapé-Açú e Santarém. Os resultados demonstraram uma prevalência de 14,8/10.000hab de casos de hanseníase entre os contatos examinados. A soropositividade do ML Flow nos casos índices foi de 53,42% em pacientes multibacilares e 13,33% nos contatos intradomiciliares. Houve associação direta de positividade do ML Flow nos contatos intradomiciliares com o índice baciloscópico do caso índice. Não houve associação direta do tempo de convivência e a consanguineidade do caso índice em relação ao teste ML Flow. Houve associação entre a positividade do teste ML Flow e a realização da vacina BCG entre os contatos. Estes resultados indicam que a introdução do teste ML Flow poderia servir como instrumento auxiliar no monitoramento dos casos e seus contatos, tornando-se de grande relevância na vigilância epidemiológica da hanseníase.

A Leishmaniose é uma doença causada pelo protozoário Leishmania sp, podendo acometer homem e animais dependendo da espécie do parasita, São transmitidos pelos flebotomíneos fêmeas, insetos do gênero Lutzomyia, que ao exercer o hematofagismo inoculam as formas promastigota infectantes, mas recentemente, tem sido levantado hipóteses sobre a transmissão por carrapatos. Segundo a vigilância epidemiológica de Imperatriz-MA a cidade é endêmica tanto para Leishmaniose Tegumentar (LT) quanto para a Leishmaniose Visceral (LV). Este trabalho teve como objetivo principal investigar a presença de DNA de Leishmania sp em carrapatos coletados de cães atendidos em petshop e Centro de Controle de Zoonoses do município de Imperatriz utilizando a técnica de PCR. O DNA foi extraído a partir de 640 carrapatos fêmeas e testadas utilizando o primer que amplifica o gene de mini-exon de Leishmania sp. Os carrapatos foram coletados de 41 cães de diferentes bairros da cidade de Imperatriz. A maioria dos carrapatos foram identificados como Rhipicephalus sanguineus. Os seguintes sinais clínicos sugestivos de leishmaniose foram observados nos cães: onicogrifose em 53,65% (22/41); úlceras em 63,41% (26/41), a perda de cabelo e inapetência em 39,02% (16/41). Cento e setenta carrapatos (26,56%) coletados de 16 cães apresentaram DNA de Leishmania do subgênero Viannia, responsável pela forma cutânea da doença. Não foi detectado nenhum DNA de Leishmania infantum chagasi. Carrapatos infectados foram coletados de ambos os cães sintomáticos e assintomáticos. Embora ainda não tenha sido demonstrado que os carrapatos possam transmitir Leishmania aos cães sob condições naturais, o resultado deste estudo tem vários aspectos importantes, pois é um método não-invasivo de detecção, capaz de diferenciar os grupos de parasitas em circulação, em especial se os animais não têm lesões, pode ser um indicador biológico em locais onde não é feito uma investigação sorológica e nem entomológica, podendo dar suporte aos programas de vigilância de saúde local.

O presente estudo descreve a avaliação operacional das açoes de controle do programa da hanseniase nas unidades de saúde do distrito administrtivo do Guamá- dagua do municipio de Belém no Estado do Pará. Trata de um estudo quantitativo ecológico do tipo transversal. Realizada no periodo de 2005 a 2010 em 11 unidades de saúde sendo 05 Centros de saude e 06 casas familias . Os dados utilizados foram secundários obtidos através do Sistema de informação de agravos de notificação- SINAN relacionado a 05 indicadores operacionais utilizados pelo Ministerio da Saúde para avaliação do Programa de Controle da Hanseniase e os dados primários coletados por meio de entrevistas com os profissionais de saúde . Os resultados encontrados no distrito foram: coeficiente de detecção no periodo de 22,6 a 39,7 casos de hanseníase por 100.000 habitantes muito alto de acordo com os parametros do MS.Na avaliação de incapacidade no momento do diagnóstico o resultado encontrado foi regular (81,3%) levando-se em consideração o total dos casos notificados.Evidenciou-se uma precariedade na avaliação do grau de incapacidade dos casos curados em todo o período de estudo. Quanto as altas curadas o percentual encontrado foi acima de 90% na maioria das unidades.Observou-se que o abandono de tratamento nas unidades do Distrito Dagua se manteve estável, apresentando percentuais abaixo de 10% em (6) seis das onze unidades.Identificou-se que as unidades do bairro da Terra Firme contribuíram para elevação dos percentuais de alta por abandono.Na entrevista realizada com profissionais sobre as capacitações recebidas, a associação entre as variáveis, aptidão para diagnosticar e tratar hanseníase e complicações e ou reações, com as variáveis como idade, categoria profissional e tempo de serviço. identificou-se que a variável tempo de serviço foi considerada estatisticamente significante com um p= 0,0206. Conclui-se que a qualidade do serviço nas unidades do Distrito dagua esta aquém do preconizado em função do real papel e cobertura das equipes de saude da familia e que o controle da hanseníase como problema de saúde pública em Belém requer medidas adicionais de vigilância epidemiológica, além daquelas que atualmente vêm sendo utilizadas.

OBJETIVO Analisar mudanças espaciais no risco de Aids e a relação entre incidência da doença e variáveis socioeconômicas. MÉTODOS Estudo caso-controle espacial, de base populacional, realizado em Rondônia, Brasil, com 1.780 casos notificados pelo Sistema de Vigilância Epidemiológica e os controles a partir de dados demográficos de 1987 a 2006. Os casos foram agrupados em cinco períodos de cinco anos consecutivos. Um modelo aditivo generalizado foi ajustado aos dados. O status dos indivíduos (caso ou controle) foi considerado como a variável dependente e independente: um alisamento ( spline ) bidimensional das coordenadas geográficas e variáveis socioeconômicas municipais. Os valores observados para o teste Moran I foram comparados com a distribuição de referência dos valores obtidos em condições de aleatoriedade espacial. RESULTADOS O risco de Aids apresentou padrão espacial e temporal marcado. A incidência associou-se a indicadores socioeconômicos municipais, como urbanização e capital humano. As maiores taxas de incidência de Aids ocorreram em municípios ao longo da rodovia BR-364; os resultados do teste Moran I mostram correlação espacial positiva associada à contiguidade dos municípios com a rodovia, no terceiro e quarto períodos (p = 0,05). CONCLUSÕES A incidência da doença foi maior em municípios de maior riqueza econômica e urbanização e naqueles cortados pelas estradas principais de Rondônia. O rápido desenvolvimento associado à ocupação de regiões remotas pode ser acompanhado por aumento de riscos à saúde.

This study aimed to analyze the spatial distribution of dengue risk and its association with socio-environmental conditions. This was an ecological study of the counts of autochthonous dengue cases in the municipality of Campinas, São Paulo State, Brazil, in the year 2007, aggregated according to 47 coverage areas of municipal health centers. Spatial models for mapping diseases were constructed with Bayesian hierarchical models, based on Integrated Nested Laplace Approximation (INLA). The analyses were stratified according to two age groups, 0 to 14 years and above 14 years. The results indicate that the spatial distribution of dengue risk is not associated with socio-environmental conditions in the 0 to 14 year age group. In the age group older than 14 years, the relative risk of dengue increases significantly as the level of socio-environmental deprivation increases. Mapping of socio-environmental deprivation and dengue cases proved to be a useful tool for data analysis in dengue surveillance systems.

Congenital toxoplasmosis is a serious public health case, for it causes irreversible damage to the embryo/fetus, which may cause its death. The identification and the care to pregnant women with suspect acute toxoplasmosis (IgM+) is performed in prenatal monitoring. This study aimed to measure the incidence and know the profile of positive pregnant women for toxoplasmosis in a Basic Health Unit (BHU) in Matão - SP, between the years 2011 to 2013. This is a retrospective descriptive study, from the medical records of pregnant women attended. The project was approved by the Municipal Departament of Health and BHU was chosen along the Municipal Epidemiological Surveillance. From 2011 to 2013, 189 women began prenatal care in the unit, an annual median of 71(±26.91), of which 17 (8.99%) were positive for the serological test indicative of acute phase (IgM+). The distribution over the trial period was: four cases in 2011, twelve cases in 2012 and one in 2013. Pregnant women IgM positive for toxoplasmosis attend by BHU were: age 24(±5.47) years; color: equally distributed among white, black and brown; as the number of pregnancies: multiparous (2±0.97), most of them with a cesarean delivery as obstetric history and possessed no other risk factors associated with pregnancy (94.12%); gave entrance at BHU with 13.65(±7.35) weeks of gestation and had a median of 5(±2.36) consultation on their prenatal care. The examination for toxoplasmosis was requested as recommended by the Health Ministry (HM) and the medication prescribed was Roxamicina® - spiramycin, as soon as the test results (IgM+) arrived. Of the 17 pregnant women, only 10 completed the pre-natal at BHU - attendance at the postpartum consult (58.8%). Of these, the deliveries were vaginal (55.55%), made preterm with 36.5 weeks of gestation at the Municipal Hospital. The babies were born alive (100%) with the weight of 2.68(±0.77) Kg and required special care hospital scope. From the ...

The notification of the occurrence or suspicion of violence is mandatory for health professionals and is a key tool for epidemiological surveillance and the definition of public policies for prevention and intervention. However, professionals feel unprepared for this assignment, which renders underreporting prevalent. To address this issue, the objective is to identify the means available to the professional to submit notification as well as ensure due process follow-up. For this purpose, research and document analysis was conducted in Brazilian legislation, ordinances, and government programs, codes of ethics and consultation of the literature in databases on the subject over a period of five years to establish a brief comparative analysis with other countries. The conclusion drawn is that while some measures are inapplicable, knowledge about the appropriate process for the notification and routing to specific organs will enable healthcare professionals to make the appropriate decisions for the protection and safety of the victim, besides the measures in order to change this situation of violence in the country.

Objective: to identify patterns in the spatial and temporal distribution of cases of dengue fever occurring in the city of Cruzeiro, state of Sao Paulo (SP).Methods: an ecological and exploratory study was undertaken using spatial analysis tools and data from dengue cases obtained on the SinanNet. The analysis was carried out by area, using the IBGE census sector as a unit. The months of March to June 2006 and 2011 were assessed, revealing progress of the disease. TerraView 3.3.1 was used to calculate the Global Moran's I, month to month, and the Kernel estimator.Results: in the year 2006, 691 cases of dengue fever (rate of 864.2 cases/100,000 inhabitants) were georeferenced; and the Moran's I and p-values were significant in the months of April and May (TM = 0.28; p = 0.01; I-M = 0.20; p = 0.01) with higher densities in the central, north, northeast and south regions. In the year 2011, 654 cases of dengue fever (rate of 886.8 cases/100,000 inhabitants) were georeferenced; and the Moran's I and p-values were significant in the months of April and May (I, = 0.28; p = 0.01; I-M = 0.16; p = 0.05) with densities in the same regions as 2006. The Global Moran's I is a global measure of spatial autocorrelation, which indicates the degree of spatial association in the set of information from the product in relation to the average. The I varies between -1 and +1 and can be attributed to a level of significance (p-value). The positive value points to a positive or direct spatial autocorrelation.Conclusion: we were able to identify patterns in the spatial and temporal distribution of dengue cases occurring in the city of Cruzeiro, SP, and locate the census sectors where the outbreak began and how it evolved.

We interviewed 21 farmers in order to access which sanitary practices adopted in the production systems of beef cattle on farms located in São Paulo, Mato Grosso, Mato Grosso do Sul and Rondonia. The survey was conducted through a qualitative approach to the collection of data obtained through questionnaire and personal interview with the landowners. We questioned the attitudes and sanitation procedures in these current production systems such as veterinary assistance, preventive health practices and disease surveillance, knowledge of health hazards for the safe production of food, animal feed, vaccine and immunizations, registration system, measures with newborns, products used in the environment and animals, grace period, employee training, destination of the dead animals, among others. Along with the data found that only 30% of properties had veterinary care, 67% said they meet the expiration dates of the products, although it was not mentioned on the products if there were any. In only 48% of properties were veterinarians who prescribed drugs to animals. Only two of the owners confirmed buying and using expired products in animals and only 48% have received some training on the property. In this setting, it is evident that farmers should be better prepared for insertion of its products in a highly demanding and competitive market. In this context, add value to the product depends mainly on the condition of sanitation of the herds.

Milk is considered a nutritionally complete food but it is also an excellent substrate for microbial growth. Therefore, it may pose a risk to consumers’ health. The aim of this study was to collect data on the occurrence of gastroenteritis outbreaks caused by the intake of milk and dairy products in the state of São Paulo, from 2000 to 2010. The data were collected from the records on foodborne illness outbreaks kept by the Division of Waterborne and Foodborne Diseases of the Center for Epidemiological Surveillance of the Department of Health of the State of São Paulo. A total of 239 outbreaks were notifi ed. They involved 2.418 cases related to the consumption of dairy products during the study period. The etiological agents were identifi ed in 79 outbreaks (33.0%). They were mostly bacteria (84.8%), especially Staphylococcus aureus. Most outbreaks occurred at home (59.4%) and during the months of January (14.2%) and July (12.5%). Most (24.1%) of the affected individuals aged 20 to 49 years. The results shows the need of better manufacturing and handling practices, as well as increasing the awareness of the population and relevant agencies about the importance of notifying cases and implementing preventive measures to ensure food safety.
