The present situation regarding lymphatic filariasis in Cabo de Santo Agostinho, Pernambuco, Northeast Brazil

A cross-sectional population-based survey on the occurrence of lymphatic filariasis was carried out in the municipality of Cabo de Santo Agostinho, Pernambuco, Northeast Brazil. 7,650 individuals of both sexes were examined (from 1,416 households) of whom six tested positive for microfilaria according to the thick blood diagnostic test. The age of the individuals examined varied from 0 to 98 (averaging 26.6 years), whilst the age of the microfilaria-positive individuals varied from 11 to 29, averaging 22.5 years. Five of the six positive cases were male. These cases were residents of the following areas: Pista Preta (one case); Ponte dos Carvalhos (four cases); and Pontezinha (one case). This last case from Pontezinha was autochthonous. Of the individuals examined, 109 (1.4%) cited complaints relating to filariasis. These results suggest that filariasis is being transmitted in the municipality of Cabo de Santo Agostinho, a finding that establishes the need to carry out disease control activities, and to collaborate with the planning of the national programme for the elimination of filariasis.

First record of Anopheles (Anopheles) costai Fonseca & Ramos, 1939 in Espírito Santo State, Brazil

Field collections of immatures and adults of Culicidae were carried out in the Rio Doce Valley, Espírito Santo State, aiming to increase knowledge on the anopheline species of that region. Considering all Culicidae species collected, among other anopheline it is noteworthy the presence of Anopheles darlingi, An. oswaldoi and An. costai. Regarding to An. darlingi, responsible for malaria outbreak in the low lands in that state, it was expected to confirm its presence in the area. The register of specimens of An. costai in the field collections is relevant, increasing the geographical distribution of the species and representing better knowledge of the Series Arribalzagia of the subgenus Anopheles.

Intestinal parasites in a quilombola community of the Northern State of Espírito Santo, Brazil

The aim of this study was to determine the occurrence of intestinal parasites in a quilombola community from the northern Espírito Santo, Brazil. Descendants of slaves who arrived in Brazil in the sixteenth century, this population settled in the municipality of São Mateus in 1858. Fresh fecal samples from 82 individuals who agreed to participate in the study were collected between August 2009 and July 2010, and immediately sent to the Clinical Laboratory of the Centro Universitário Norte do Espírito Santo of the Universidade Federal do Espírito Santo for analysis. Out of all the participants, 36 (43.9%) were male and 46 (56.1%) were female, whose ages ranged from six to 85 years. The study of the occurrence of intestinal parasites indicated that 35 individuals (42.7%) were infected with at least one intestinal parasite. Among helminths, the most frequent were hookworms, with a rate of 14.6%. With regard to protozoa, Entamoeba coli, Entamoeba histolytica/Entamoeba dispar and Endolimax nana stood out, with frequencies of 23.2%, 8.5% and 4.9%, respectively. The occurrence of biparasitism was observed in 13 of the 82 subjects, accounting for 15.8%, and no cases of multiple parasitic infections were observed. It was concluded that the reduction of cases of intestinal diseases due to parasites will only be achieved with the improvement of basic sanitation and quality of life of quilombola populations.

Distribuição geográfica da leishmaniose tegumentar americana no Estado do Espírito Santo - Brasil

Com base nos registros de 730 pacientes portadores de Leishmaniose Tegumentar Americana (LTA) referentes ao período de janeiro de 1972 a dezembro de 1982, os autores realizaram um estudo da distribuição geográfica dessa parasitose no Estado do Espírito Santo. Os pacientes procediam de 36 dos 53 municípios que compõem o Estado, destacando-se Viana e Cariacica como os de maior prevalência, somando juntos 442 casos (60,54%), com 259 destes residindo numas poucas localidades, contínuas entre si, formando uma área endêmica, com transmissão ocorrendo provavelmente no peri e intra-domicílio. Esta área de alta endemicidade, pertencente principalmente ao vale do rio Formate, estende-se também ao município de Domingos Martins através da localidade de Biriricas. Nos demais municípios a LTA caracterizou- se como uma doença profissional de ocorrência antiga no Estado.

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.

Abscesso piogênico do fígado e esquistossomose mansônica: observações no Estado do Espírito Santo

Recentemente, foi demonstrado que a forma toxêmica da esquistossomose mansônica em crianças pode serfator predisponente para abscesso piogênico do fígado (APF). Como no Estado do Espírito Santo, a esquistossomose é endêmica em grande parte do estado e os APF são freqüentemente diagnosticados no Hospital Infantil Nossa Senhora da Glória de Vitória, realizou-se revisão dos casos de APF diagnosticados entre maio de 1991 e abril de 1994, com a finalidade de identificar-se os casos com infecção esquistossomótica e a sua procedêitcia. Identificaram-se 65 casos de APF e 39 apresentavam exame de fezes registrado no prontuário, sendo 3 positivos para Schistosoma mansoni e 29 positivos para outros helmintos intestinais, principalmente áscaris e tricocéfalo. A procedência dos pacientes mostrou que 7 (10,6%) eram provenientes de zona endêmica da esquistossomose. A associação APF e esquistossomose mostrou-se pequena e não há grande sobreposição na distribuição geográfica das duas doenças. Por outro lado a alta prevalência de infecção por outros helmintos intestinais e o grande número de abscessos piogênicos criptogenéticos diagnosticados, faz pensar que as infecções helmínticas com larvas que podem migrar para o fígado e formar granulomas, possam também ser um fator predisponente para o abscesso hepático em crianças.
