Breeding sites of Aedes aegypti in metropolitan vacant lots in Greater Vitória, State of Espírito Santo, Brazil

INTRODUCTION: This study aimed to evaluate the presence of Aedes aegypti in breeding sites located in vacant lots (VLs) and determine the effectiveness of VL cleaning to reduce insect foci. METHODS: Two types of VLs were sampled, the experimental VL, which was cleaned monthly, and the control VL, which was not cleaned. RESULTS: Monthly cleaning of VLs reduced the abundance of immature forms of A. aegypti. CONCLUSIONS: Strategies for combating this vector should include regular cleaning of VLs and educating the public regarding the risks of discarding waste in inappropriate areas.

Anti-Toxocara antibodies detected in children attending elementary school in Vitoria, State of Espírito Santo, Brazil: prevalence and associated factors

INTRODUCTION: The aim of this study was to evaluate the frequency of anti-Toxocara antibodies in serum from 7-year-old children attending elementary school in Vitória-ES, Brazil and to correlate these antibodies with socio-demographic factors, the presence of intestinal helminths, blood eosinophil numbers, past history of allergy or asthma, and clinical manifestations of helminth infections. METHODS: The detection of anti-Toxocara antibodies was performed using an ELISA (Cellabs Pty Ltd)on serum from 391 children who had already been examined by fecal examination and blood cell counts. Data from clinical and physical examinations were obtained for all children. RESULTS: The prevalence of anti-Toxocara antibodies was 51.6%, with no gender differences. No significant differences were observed between positive serology and the presence or absence of intestinal worms (60.3 and 51.7%, respectively; p = 0.286). The only variables significantly related to positive serology were onycophagy and the use of unfiltered water. Although eosinophilia (blood eosinophil count higher than 600/mm³) was significantly related to the presence of a positive ELISA result, this significance disappeared when we considered only children without worms or without a past history of allergy or asthma. No clinical symptoms related to Toxocara infection were observed. CONCLUSIONS: There is a high prevalence of anti-Toxocara antibodies in children attending elementary schools in Vitória, which may be partially related to cross-reactivity with intestinal helminths or to a high frequency of infection with a small number of Toxocara eggs.

Spatial analysis of new cases of leprosy in the State of Espírito Santo, Brazil, between 2004 and 2009

INTRODUCTION: Leprosy in Brazil is a public health issue, and there are many regions in the State of Espírito Santo with high endemic incidence levels of leprosy, characterizing this state as a priority for leprosy programs. The aim of this study was to determine the spatial distribution of coefficients of new cases of leprosy in the State of Espírito Santo, Brazil. METHODS: We conducted a descriptive and ecologic study based on the spatial distribution of leprosy in the State of Espírito Santo between 2004 and 2009. Data were gathered from the available records of the Espírito Santo State Health Secretary. The global and local Bayesian empirical methods were used to produce an estimate of leprosy risk, smoothing the fluctuation effects of the detection coefficients. RESULTS: The study resulted in a coefficient adjustment of new cases in 10 towns that changed their classification, among which, 2 went from low to medium, 4 from medium to high, 3 from high to very high, and 1 from very high to hyper-endemic. An average variation of 1.02, fluctuating between 0 and 12.39 cases/100,000 inhabitants, was found in a comparative calculation between the Local Ebest value and the average coefficient of new leprosy cases in the State of Espírito Santo. CONCLUSIONS: The spatial analysis of leprosy favors the establishment of control strategies with a better cost-benefit relationship since it reveals specific and priority regions, thereby enabling the development of actions that can interfere in the transmission chain.

Malignancies in HIV/AIDS patients attending an outpatient clinic in Vitória, State of Espírito Santo, Brazil

INTRODUCTION: The present study investigated cancer prevalence and associated factors among HIV-infected individuals attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. METHODS: A sectional study was conducted among HIV infected adults attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. Demographic, epidemiological and clinical data were abstracted from medical records, including cancer diagnoses; nadir and current CD4 cell count, HIV viral load, time on antiretroviral treatment (ART), type of ART and smoking status. RESULTS: A total of 730 (91.3%) patients were included in the study. Median age was 44.0 [interquartile range (IQR): 35-50.3] years; median time since HIV diagnosis was 5.5 years (IQR: 2-10); 60% were male; and 59% were white. Thirty (4.1%) cases of cancer were identified of which 16 (53%) were AIDS defining cancers and 14 (47%) were non-AIDS defining malignancies. Patients diagnosed with cancer presented higher chance of being tobacco users [OR 2.2 (95% CI: 1.04-6.24)]; having nadir CD4 ≤200 cells/mm³ [OR 3.0 (95% CI: 1.19-7.81)] and higher lethality [OR 13,3 (95% CI: 4,57-38,72)]. CONCLUSIONS: These results corroborate the importance of screening for and prevention of non-AIDS defining cancers focus in HIV-infected population, as these cancers presented with similar frequency as AIDS defining cancers.

First description of autochthonous canine visceral leishmaniasis in the metropolitan region of Vitória, State of Espírito Santo, Brazil

INTRODUCTION: We investigated autochthonous canine visceral leishmaniasis (CVL) in the metropolitan region of Vitória (MRV), an area in which a human case was previously reported. METHODS: Serological, parasitological, and molecular tests were performed in 201 dogs. RESULTS: Twenty-six (13%) and 12 (6%) dogs were identified as positive using in-house enzyme-linked immunosorbent assay (ELISA) and rK39 tests, respectively. Two dogs had a positive culture for Leishmania chagasi, and 4 were polymerase chain reaction (PCR)-positive for Leishmania spp. One positive dog belonged to the aforementioned patient. CONCLUSIONS: Although the responsible vector was not found, our results provide evidence of autochthonous CVL in the MRV, a non-endemic area for VL.

AIDS tendencies in São Mateus microregion, state of Espírito Santo, and Brazil from 1999 to 2008

INTRODUCTION: In Brazil, AIDS has been described as a multi-faceted pandemic. This study aimed to describe the trends of AIDS in São Mateus microregion, in Espírito Santo, and in Brazil, from 1999 to 2008. METHODS: Data were collected from the Notification Offences System, and a trend analysis was made. RESULTS: Microregion-based results are close to the state and national levels but with particular features that indicate the presence of regional sub-epidemics. CONCLUSIONS: Despite progress in nearly thirty years of the epidemic, AIDS remains an incurable disease, and prevention is still the best defense against it together with the implementation of specific public policies.

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.

Hepatitis virus and hepatocellular carcinoma in Brazil: a report from the State of Espírito Santo

IntroductionFew studies have examined hepatocellular carcinoma (HCC) in Brazil, and the incidence and risk factors for this type of malignancy vary greatly geographically. In this paper, we report several risk factors associated with HCC diagnosed at the University Hospital in Vitória, ES, Brazil.MethodsWe reviewed 274 cases of HCC (January 1993 to December 2011) in which hepatitis B (HBV) and C (HCV) virus infection and chronic alcoholism were investigated. A diagnosis of hepatocellular carcinoma was confirmed by histology or by the presence of a characteristic pattern on imaging.ResultsHCC with associated liver cirrhosis was noted in 85.4% of cases. The mean ages of men and women were 56.6 years and 57.5 years, respectively. The male-to-female ratio was 5.8:1. Associated risk factors included the following: HBV, 37.6% (alone, 23.4%; associated with chronic alcoholism, 14.2%); HCV, 22.6% (alone, 13.5%; associated with chronic alcoholism, 9.1%), chronic alcoholism, 17.1%, non-alcoholic steatohepatitis, 2.6% and cryptogenic, 19.3%. The male-to-female ratio was higher in cases associated with HBV or chronic alcoholism compared with HCV-associated or cryptogenic cases. In 40 cases without associated cirrhosis, the male-to-female ratio and mean age were lower than those in cirrhosis-associated cases.ConclusionsThese results demonstrate that the main risk factor associated with HCC in the State of Espírito Santo is HBV. Chronic alcoholism is an important etiological factor, alone or in association with HBV or HCV infection.

Phlebotominae sand flies (Diptera: Psychodidae): potential vectors of American cutaneous leishmaniasis agents in the area associated with the Santo Antônio Hydroelectric System in Western Amazonian Brazil

INTRODUCTION: An entomological study was conducted as part of a vector-monitoring program in the area associated with the Santo Antônio hydroelectric system in State of Rondônia, Western Amazonian Brazil. METHODS: Fourteen sampling sites were surveyed to obtain data on the potential vectors of Leishmania spp. in the area. Sand flies were collected from 2011 to 2014 during the months of January/February (rainy season), May/June (dry season), and September/October (intermediary season) using light traps arranged in three vertical strata (0.5, 1, and 20m). RESULTS : A total of 7,575 individuals belonging to 62 species/subspecies were collected. The five most frequently collected sand flies were Psychodopygus davisi (Root) (36.67%), Trichophoromyia ubiquitalis (Mangabeira) (8.51%), Nyssomyia umbratilis (Ward & Fraiha) (6.14%), Bichromomyia flaviscutellata (Mangabeira) (5.74%), and Psychodopygus complexus (Mangabeira) (5.25%). These species have been implicated in the transmission of American cutaneous leishmaniasis agents in the Brazilian Amazon region and described as potential vectors of this disease in the study area. CONCLUSIONS: Additional surveillance is needed, especially in areas where these five species of sand fly are found.

Assessment of schistosomiasis in the semi-arid Northeast region of Brazil: the São Francisco River large-scale water transposition project

Abstract: INTRODUCTION Risk of schistosomiasis expansion to semi-arid northeastern Brazil under the influence of the Integration Project of the São Francisco River (IPSFR) was assessed. METHODS: Stool examinations of schoolchildren, epidemiological investigation, and survey of the local host snail Biomphalaria straminea were performed in five IPSFR municipalities. RESULTS Six of 4,770 examined schoolchildren were egg-positive for Schistosoma mansoni. Biomphalaria straminea was widespread, but not naturally infected with S. mansoni. Snails experimentally exposed to two laboratory S. mansoni strains yielded infection indices of 1-4.5%. CONCLUSIONS: There is evidence of active schistosomiasis transmission in the area; thus, intensive surveillance actions are required.

Os Hesperiidae (Lepidoptera, Hesperioidea) da RPPN Klagesi, Santo Antônio do Tauá, Pará, Brasil: nova contribuição para o conhecimento da biodiversidade da área de endemismo Belém

Embora a região Belém seja uma das áreas mais exploradas da Amazônia com coletas desde o século XVIII, grande parte das informações se encontra dispersa em coleções internacionais, o que dificulta a reunião de dados e interpretações biogeográficas. Visando ampliar o conhecimento da fauna de lepidópteros da região, o presente estudo levantou uma lista de 225 espécies de Hesperiidae encontradas na RPPN Klagesi durante aproximadamente 24 anos de amostragens esporádicas, embora mais freqüentemente na última década. São adicionadas 113 espécies previamente não relacionadas para a região, a qual passa a ser a área de maior riqueza conhecida de Hesperiidae dentre todas as regiões de endemismo da Amazônia brasileira até então inventariadas. No entanto, o conhecimento da diversidade de Hesperiidae em outras áreas de endemismo é tão restrito, que a riqueza de espécies deve ser utilizada apenas como indicador de esforço amostral ao invés de inferências biogeográficas. Três das regiões de endemismo ainda não apresentam nenhum inventário de fauna (Xingú, Napo e Imeri), enquanto as demais são reconhecidas por um ou poucos inventários. Portanto, para que a lepidopterofauna amazônica seja realmente conhecida e utilizada em estudos de biogeografia e conservação, são necessários esforços direcionados nestas regiões ainda totalmente desconhecidas ou mesmo a reunião de informações sobre coletas já realizadas, cujo material se encontra disperso em coleções pelo mundo.

Tentativas de suicídio e suicídio em município de cultura pomerana no interior do estado do Espírito Santo

OBJETIVO: Descrever o perfil das tentativas de suicídio e mortalidade por suicídio no município de Santa Maria de Jetibá, interior do Espírito Santo, no período de 2001 a 2007. MÉTODO: Estudo descritivo, observacional e de abordagem quantitativa. A identificação dos casos de tentativas de suicídio e suicídios ocorreu por meio dos Boletins de Ocorrência Policial da Polícia Militar do Município, onde foram selecionados todos os casos. Para análise dos dados, foram utilizadas tabelas de frequência e os testes de hipótese t Student e Qui-quadrado. RESULTADOS: O coeficiente médio de mortalidade por suicídio foi de 12,9/100.000. Verificou-se que as mulheres realizam mais tentativas de suicídio, enquanto os homens foram mais eficientes, cometendo mais suicídio (p = 0,008). A média de idade para as vítimas de tentativas de suicídio foi de 30 ± 10,1 anos e de suicídio 42 ± 14,9 anos (p = 0,001). Os meios mais utilizados para os casos de suicídio foi o enforcamento (57,1%), enquanto para as tentativas foi o envenenamento por agrotóxico (42,5%). CONCLUSÃO: Verificou-se que o perfil dos suicidas se diferencia dos que tentam, especialmente segundo o sexo, a idade e os meios utilizados, enfatizando a necessidade de se desencadear discussões acerca de programas, tratamento e prevenção para os grupos mais vulneráveis.
