Foco de leishmaniose tegumentar americana nos municípios de Viana e Cariacica, Estado do Espirito Santo, Brasil

Descreve-se um foco de leishmaniose tegumentar americana abrangendo quatro localidades dos municípios de Viana e Cariacica situados próximo ao litoral do Estado do Espírito Santo, Brasil. Foram diagnosticados 71 casos no período de maio de 1978 a dezembro de 1982. A confirmação laboratorial foi obtida pela intradermorreação de Montenegro em 66 pacientes e pelo encontro do parasita em 15. A faixa etária mais acometida foi a de 0-10 anos. Amostras do parasita isoladas de 3 pacientes e de 27 cães foram classificadas como Leishmania braziliensis braziliensis. De apenas dois Proechimys iheringi, entre 257 mamíferos silvestres estudados, isolou-se Leishmania, que foi identificada como Leishmania mexicana aristedesi. As espécies de flebotomíneos mais numerosas (Lutzomyia intermedia, L. fischeri e L. migonei) apresentaram um elevado grau de adaptação aos ambientes intra e peri-domibiliar. Levantou-se a hipótese da transmissão estar ocorrendo no intra e peri-domicílio.

Antibodies against Bovine herpesvirus 1 in dairy herds in the state of Espirito Santo, Brasil

Bovine herpesvirus 1 (BoHV-1) causes major losses in worldwide livestock, affecting the respiratory and reproductive tracts of bovine. In the past decades, the number of cases in Brazil has been gradually increasing. Therefore, it is important to assess the distribution of infection in different regions of the country. In the state of Espírito Santo (ES) the BoHV 1 infection rate in dairy cattle herds is unknown. Thus, the aim of this study was to detect neutralizing antibodies against BoHV-1 in serum samples from 1,161 non-vaccinated cows from 59 dairy cattle herds in 23 municipalities of the Metropolitan, North, Northwest and South macro-regions. The identification of seropositive cows was evaluated by the virus neutralization test. The results showed that of all serum samples evaluated 775 (66.75%) had neutralizing antibodies against BoHV-1. Moreover, all herds were found positive; however, the percentage of positive cows varied among regions; 49.06%, 62.15%, 67.21% and 80.04% for the Metropolitan, South, North and Northwest macro-regions, respectively. In this study, the results clearly indicate the dissemination of the viral agent in dairy cattle in the ES state, requiring the monitoring and control of diseases related to BoHV-1 infection.

Air pollution and its impacts on health in Vitoria, Espirito Santo, Brazil

ABSTRACT OBJECTIVE To analyze the impact of air pollution on respiratory and cardiovascular morbidity of children and adults in the city of Vitoria, state of Espirito Santo. METHODS A study was carried out using time-series models via Poisson regression from hospitalization and pollutant data in Vitoria, ES, Southeastern Brazil, from 2001 to 2006. Fine particulate matter (PM10), sulfur dioxide (SO2), and ozone (O3) were tested as independent variables in simple and cumulative lags of up to five days. Temperature, humidity and variables indicating weekdays and city holidays were added as control variables in the models. RESULTS For each increment of 10 µg/m3 of the pollutants PM10, SO2, and O3, the percentage of relative risk (%RR) for hospitalizations due to total respiratory diseases increased 9.67 (95%CI 11.84-7.54), 6.98 (95%CI 9.98-4.17) and 1.93 (95%CI 2.95-0.93), respectively. We found %RR = 6.60 (95%CI 9.53-3.75), %RR = 5.19 (95%CI 9.01-1.5), and %RR = 3.68 (95%CI 5.07-2.31) for respiratory diseases in children under the age of five years for PM10, SO2, and O3, respectively. Cardiovascular diseases showed a significant relationship with O3, with %RR = 2.11 (95%CI 3.18-1.06). CONCLUSIONS Respiratory diseases presented a stronger and more consistent relationship with the pollutants researched in Vitoria. A better dose-response relationship was observed when using cumulative lags in polynomial distributed lag models.

Angiostrongylus costaricensis: first record of its occurrence in the State of Espirito Santo, Brazil, and a review of its geographic distribution

Abdominal angiostrongyliasis is a parasitic disease caused by Angiostrongylus costaricensis, a metastrongylid nematode with wide geographic distribution, occurring from the United States to Argentina. In Brazil, the disease has been reported from the States of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Federal District of Brasilia and Minas Gerais. We report here a case of abdominal angiostrongyliasis in a 9-year-old girl, from Itatiba, State of Espirito Santo, Brazil, submitted to exploratory laparotomy for acute abdomen. Extensive inflammatory lesions of terminal ileum and cecum, with perforations of the first, were present, and ileocecal resection was performed. The pathological picture was characterized by transmural inflammatory granulomatous reaction, extensive eosinophilic infiltration, eosinophilic vasculitis and the presence of worms within a mesenteric artery branch, with histological features of metastrongylid nematodes. This case report contributes to a better knowledge of the geographic distribution of this parasite in Brazil, suggesting that abdominal angiostrongyliasis may represent a disease of medical importance, more than a rarity of academic interest.

Labrea-like hepatitis in Vitoria, Espirito Santo state, Brazil: report of a case

A case of fulminat hepatitis with microvesicular steatosis resembling Labrea 's fever, diagnosed in Vitoria (ES) is reported. The 16 year old bcy presented with severe epistaxis, agitation, jaundice and hemorrhagic vomiting and died two days after admission to the emergency unit of the Vnivesity Hospital. The disease started five days before with fever, myalgias, dark urine and jaundice andprogressed withpsychic agitation, torpor and coma. The liver andspleen were notpalpable. HBsAg was negative in the serum. The autopsy showed acute hepatitis with tylic necrosis confluent in the midizonal and periportal areas with massive microvesicular steatosis in the remaining hepatocytes. Mononuclear cellspredominated in the exudate. The reticulum showed condensation in the necrotic areas without typical bands of collapse. The portal tracts were edematous with mononuclear infiltration and mild bile duct proliferation. Absence of cholestasis. Exceptfor the confluent midzonalandperiportal necrosis this case showed several clinical and morphological aspects of the Labreafever describedfrom the East Amazon, demonstrating that the anatomical picture of this disease probabty is not in related to afactor peculiar to the Amazon region.

Spatial distribution of leprosy in areas of risk in Vitoria, State of Espirito Santo, Brazil, 2005 to 2009

Introduction Leprosy remains a relevant public health issue in Brazil. The objective of this study was to analyze the spatial distribution of new cases of leprosy and to detect areas with higher risks of disease in the City of Vitória. Methods The study was ecologically based on the spatial distribution of leprosy in the City of Vitória, State of Espírito Santo between 2005 and 2009. The data sources used came from the available records of the State Health Secretary of Espírito Santo. A global and local empirical Bayesian method was used in the spatial analysis to produce a leprosy risk estimation, and the fluctuation effect was smoothed from the detection coefficients. Results The study used thematic maps to illustrate that leprosy is distributed heterogeneously between the neighborhoods and that it is possible to identify areas with high risk of disease. The Pearson correlation coefficient of 0.926 (p = 0.001) for the Local Method indicated highly correlated coefficients. The Moran index was calculated to evaluate correlations between the incidences of adjoining districts. Conclusions We identified the spatial contexts in which there were the highest incidence rates of leprosy in Vitória during the studied period. The results contribute to the knowledge of the spatial distribution of leprosy in the City of Vitória, which can help establish more cost-effective control strategies because they indicate specific regions and priority planning activities that can interfere with the transmission chain.

Factors related to severe dengue during an epidemic in Vitoria, State of Espirito Santo, Brazil, 2011

Introduction The prognosis of dengue depends on early diagnosis and treatment, which can help prevent severe forms whose characteristics were evaluated here. Methods A cross-sectional study was conducted involving dengue cases in Vitória, State of Espírito Santo, Brazil, in 2011. Results Two health regions registered 56.3% of 371 cases of severe dengue. Of these cases, 21.3% presented with dengue hemorrhagic fever. There were associations between dengue hemorrhagic fever with younger ages and a longer time before receiving care. Conclusions There was a greater involvement of dengue hemorrhagic fever in young people. Delay in care, poor urban quality and high endemicity were identified as possible risk factors for dengue severity.

Rainfall erosivity and rainfall return period in the experimental watershed of Aracruz, in the coastal plain of Espirito Santo, Brazil

Knowledge on the factors influencing water erosion is fundamental for the choice of the best land use practices. Rainfall, expressed by rainfall erosivity, is one of the most important factors of water erosion. The objective of this study was to determine rainfall erosivity and the return period of rainfall in the Coastal Plains region, near Aracruz, a town in the state of Espírito Santo, Brazil, based on available data. Rainfall erosivity was calculated based on historic rainfall data, collected from January 1998 to July 2004 at 5 min intervals, by automatic weather stations of the Aracruz Cellulose S.A company. A linear regression with individual rainfall and erosivity data was fit to obtain an equation that allowed data extrapolation to calculate individual erosivity for a 30-year period. Based on this data the annual average rainfall erosivity in Aracruz was 8,536 MJ mm ha-1 h-1 yr-1. Of the total annual rainfall erosivity 85 % was observed in the most critical period October to March. Annual erosive rains accounted for 38 % of the events causing erosion, although the runoff volume represented 88 % of the total. The annual average rainfall erosivity return period was estimated to be 3.4 years.

Características e tendência da AIDS entre idosos no Estado do Espírito Santo

INTRODUÇÃO: A AIDS entre adultos mais velhos é um problema de saúde pública emergente. Comparamos o perfil epidemiológico e sociodemográfico, bem como a evolução e a tendência da epidemia entre homens e mulheres nas faixas etárias de 50 anos e mais e 20 a 39 anos acometidos pela AIDS, no Estado do Espírito Santo, Brasil. MÉTODOS: Realizamos um estudo de série temporal, com dados secundários do SINAN/AIDS, no período de Janeiro de 1991 a dezembro 2006. RESULTADOS: Neste período, foram notificados 3.382 casos de AIDS em indivíduos com idade entre 20 e 39 anos e 551 casos entre indivíduos com 50 anos e mais. Em ambas as faixas etárias, os mais acometidos são os homens. Há diferenças referentes à raça/cor, em que a maioria dos mais velhos são brancos (45,3% - p-valor = 0,044) e os mais jovens pardos (44,7%, p-valor = 0,003). O analfabetismo prevalece entre os mais velhos (17,7% - p-valor = 0,001). Mais da metade (80%) das notificações ocorreu em municípios de médio a grande porte. A principal categoria de exposição foi a heterossexual, em ambos as faixas etárias, com maior frequência para o grupo de 50 anos ou mais (77,3% - p=0,0001). A incidência acumulada é maior para a faixa etária de 20 a 39 anos (R²=0,68); porém, vem aumentando proporcionalmente, entre as duas faixas no decorrer dos anos, com tendência de crescimento significativa para ambas (p <0,01). CONCLUSÕES: A epidemia de AIDS pode ser considerada em expansão entre mais velhos no Espirito Santo.

Estudo de mutações causadoras de cardiomiopatia hipertrófica em um grupo de pacientes no Espírito Santo, Brasil

FUNDAMENTO: A cardiomiopatia hipertrófica (CH) é a doença cardíaca hereditária mais frequente, causada por mutações nos genes codificadores para proteínas do sarcômero. Embora mais de 430 mutações tenham sido identificadas em vários continentes e países, não há relato de que isso tenha sido estudado no Brasil. OBJETIVO: Conduzir um estudo genético para identificar mutações genéticas que causam a CH em um grupo de pacientes no estado do Espírito Santo, Brasil. MÉTODOS: Usando a técnica SSCP, 12 exons dos três principais genes envolvidos com a CH foram estudados: exons 15, 20, 21, 22 e 23 do gene da cadeia pesada da β-miosina (MYH7), exons 7, 16, 18, 22 e 24 do gene da proteína C ligada à miosina (MYBPC3) e exons 8 e 9 do gene da troponina T (TNNT2). RESULTADOS: 16 alterações foram encontradas, incluindo duas mutações, uma delas possivelmente patogênica no gene MYBPC3 gene (p. Glu441Lys) e a outra patogênica já descrita no gene TNNT2 (p.Arg92Trp); 8 variações de seqüência raras e 6 variações de seqüência com frequência alélica maior do que 1% (polimorfismos). CONCLUSÃO: Com esses dados, é possível concluir que a genotipagem dos pacientes é factível em nosso meio. É possível que a variante p.Glu441Lys no exon 16 do gene MYBPC3 seja patogênica, resultando em um fenótipo mais leve do que o encontrado em associação com outras mutações. A variante p.Arg92Trp no exon 9 do gene TNNT2 não resulta em um fenótipo tão homogêneo como descrito anteriormente e pode levar à hipertrofia grave.

O consumo de calmantes e o "problema de nervos" entre lavradores

O "problema de nervos" surgiu como tema de estudo durante inquérito de morbidade referida, quando foram entrevistados 93 adultos, lavradores, em 25 comunidades rurais da região serrana do Estado do Espirito Santo, Brasil, sobre os problemas de saúde nas últimas 48h. Dentre os entrevistados, 30% relataram "problema de nervos" para si e/ou familiares, o que resultou em 34 depoimentos sobre esse problema distribuídos proporcionalmente entre colonos e proprietários e entre os sexos. Em 11 relatos (32%) o excesso de trabalho aparece como desencadeador privilegiado de "nervos". Em 88% dos casos, o uso de pelo menos uma dentre 26 drogas psicotrópicas referidas é regular, sendo a dependência explicitada em 47% deles. A referência a esses remédios sobrepõe-se ou substitui a descrição do problema em 18 relatos (53%), refletindo a introjeção do discurso e práticas médicas pela população. A fragilidade dos limites entre normal e patológico, evidente nas descrições de "nervos" obtidas, reforça o caráter de síndrome interpretada culturalmente. O consumo de calmantes concorre para a manutenção de "nervos" como fenômeno individual e do "nervoso" no papel de "doente crônico", obscurecendo os motivos de seu sofrimento. A facilidade de obtenção das drogas é discutida em relação aos macro-determinantes do consumo de medicamentos.

Prevalence of Epstein-Barr virus antibodies in healthy children and adolescents in Vitória, State of Espírito Santo, Brazil

The prevalence and age distribution of Epstein-Barr virus infection varies in different populations and there is little information about the epidemiology of this infection in Brazil. We studied the prevalence of EBV antibodies in a sample of 283 children and adolescents between 1 and 21 years old. The sample was taken from two neighborhoods in Vitória (capital city of Espirito Santo, Brazil). The São Pedro (SP) neighborhood represented an area with lower socioeconomic status and the Praias (P) neighborhood represented an area with higher SES. Anti-VCA (Virus Capsid Antigen) antibodies were detected by ELISA and anti-EBNA (Epstein-Barr Nuclear Antigen) antibodies were detected by an anti-complement immunofluorescence method, both using commercial kits. The results showed an overall prevalence rates of anti-VCA and anti-EBNA of 71% and 54% respectively. The prevalence for both anti-EBV antibodies was higher and probably the infection occurred earlier in the SP neighborhood. Among the various socioeconomic factors studied only low family income and maternal education level were significantly correlated with a higher frequency of positive serology for anti-VCA. These results demonstrate that there is a high prevalence of EBV antibodies in children and adolescents living in Vitória, that occurs more frequently at a younger age in children from families with low socioeconomic status. In addition, the results demonstrate an intermediate age distribution pattern between those reported in developed and underdeveloped countries.

Normas DRIS regionais e inter-regionais na avaliação nutricional de café Conilon

O objetivo deste trabalho foi avaliar o desempenho de normas de sistema integrado de diagnose e recomendação (DRIS) regionais e inter-regionais no diagnóstico nutricional de café Conilon (Coffea canephora). Dados foliares de N, P, K, Ca e Mg, referentes a 268 lavouras cafeeiras do Espírito Santo e de Rondônia, foram utilizados para a definição de quatro conjuntos de normas DRIS: três para condições específicas (normas regionais) e um para todas as condições testadas (normas inter-regionais). As lavouras apresentavam grandes diferenças quanto ao manejo e às condições ambientais. Após o estabelecimento das normas, os diagnósticos nutricionais obtidos a partir delas foram confrontados entre si. Todas as normas foram efetivas em proporcionar diagnósticos que distinguissem padrões nutricionais das lavouras, tanto no Espirito Santo como em Rondônia. Na norma DRIS inter-regional, as médias e os desvios-padrão das relações multivariadas entre os nutrientes apresentaram valores intermediários, em comparação aos obtidos nos conjuntos de normas regionais. Não foi constatada aleatoriedade no diagnóstico nutricional com uso das normas inter-regionais, o qual apresentou elevado grau de concordância com o das normas regionais. Normas específicas somente devem ser utilizadas nas condições em que foram geradas, enquanto normas genéricas apresentam aplicabilidade mais ampla sem prejuízo à acurácia dos diagnósticos.
