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.

CLINICAL AND EPIDEMIOLOGICAL PROFILE OF ELDERLY PATIENTS WITH CHAGAS DISEASE FOLLOWED BETWEEN 2005-2013 BY PHARMACEUTICAL CARE SERVICE IN CEARÁ STATE, NORTHEASTERN BRAZIL

By controlling the transmission of Chagas disease, the challenge of providing assistance to millions of infected patients that reach old age arises. In this study, the socioeconomic, demographic and comorbidity records of all elderly chagasic patients followed at the Pharmaceutical Care Service of the Chagas Disease Research Laboratory were assessed. The information related to the clinical form of the disease was obtained from medical records provided by the Walter Cantídio University Hospital. The profile of the studied population was: women (50.5%); mean age of 67 years; retired (54.6%); married (51.6 %); high illiteracy rate (40.2%); and family income equal to the minimum wage (51.5%). The predominant clinical forms of Chagas disease were cardiac (65.3%) and indeterminate (14.7%). The main electrocardiographic changes were the right bundle branch block (41.0%), associated or not with the anterosuperior left bundle branch block (27.4%). The average number of comorbidities per patient was 2.23 ± 1.54, with systemic arterial hypertension being the main one found (67.0%). It was found that the elderly comprise a vulnerable group of patients that associate aging with cardiac and/or digestive disorders resulting from the evolution of Chagas disease and other comorbidities, which requires special attention from health services to ensure more appropriate medical and social care.

VISCERAL LEISHMANIASIS IN PETROLINA, STATE OFPERNAMBUCO, BRAZIL, 2007-2013

Visceral leishmaniasis is a life-threatening disease of great public health relevance in Brazil. The municipality of Petrolina is an endemic area in the State of Pernambuco, Brazil. This study was designed to assess the recent expansion of VL in the municipality ofPetrolina, Pernambuco. Patients data were obtained from the Brazilian National Information System for Notifiable Diseases (SINAN). A total of 111 records from 2007 to 2013 were investigated, of which 69 were residents in Petrolina. The disease has predominantly affected 1-4 year old children (34.8%). Most of the patients were males (59.4%). Co-infection with human immunodeficiency virus occurred in 14.5% of the cases. The criterion most frequently used was the clinical and epidemiological confirmation (59.4%), with clinical cure in 78.3% of cases and one fatal outcome. Visceral leishmaniasis is endemic in Petrolina with transmission levels varying from moderate to high. The present study has shown the precariousness of the use of diagnostic tests in primary healthcare units, and this misuse has interfered with the diagnosis and treatment of cases.

Distribuição geográfica de Lutzomyia (Nyssomyia) whitmani (Antunes & Coutinho, 1939) no Estado de Mato Grosso

No Estado de Mato Grosso, 100% dos municípios apresentam registros de casos autóctones de leishmaniose tegumentar americana. O presente trabalho objetivou verificar a distribuição geográfica de Lutzomyia whitmani no estado. Mato Grosso possui três ecossistemas distintos, o cerrado, o pantanal e área de domínio amazônico. Os dados sobre a ocorrência de Lutzomyia whitmani foram obtidos a partir de relatórios de pesquisa entomológica realizados pelo Núcleo de Entomologia da Fundação Nacional de Saúde no período de 1996 a 2000 e de 2001 a 2006 pelo Laboratório de Entomologia da Secretaria Estadual de Saúde de Mato Grosso. Foram realizadas pesquisas entomológicas em 83 (59,7%) dos 139 municípios de Mato Grosso. Lutzomyia whitmani foi capturado em 70 (84,3%) municípios, com ampla distribuição em todos os tipos de vegetação.

Spatiotemporal analysis of reported cases of acute Chagas disease in the State of Pernambuco, Brazil, from 2002 to 2013

INTRODUCTION: Control strategies to eliminate the transmission of Chagas disease by insect vectors have significantly decreased the number of reported acute cases in Brazil. However, data regarding the incidence and distribution of acute Chagas disease cases in the State of Pernambuco are unavailable in the literature. METHODS: A geographical information system was used to delineate the spatiotemporal distribution profile of the cases from 2002 to 2013 in 185 municipalities of Pernambuco based on the municipality where notification occurred. The results were presented in digital maps generated by the TerraView software (INPE). RESULTS: A total of 302 cases of acute disease were recorded in 37.8% of the municipalities, for a total of 0.13 cases per 1,000,000 inhabitants per year. Out of the 302 cases, 99.3% were reported between 2002 and 2006. The most affected municipalities were Carnaubeira da Penha, Mirandiba and Terra Nova. The risk maps showed a significant decrease in the number of notifications and a concentration of cases in the Midwest region. CONCLUSIONS: This study highlights a significant decrease in new cases of acute Chagas disease in Pernambuco starting in 2006 when Brazil received an international certification for the interruption of vectorial transmission by Triatoma infestans. However, control strategies should still be encouraged because other triatomine species can also transmit the parasite; moreover, other transmission modes must not be neglected.

Hepatitis E virus infection in Brazil: results of laboratory-based surveillance from 1998 to 2013

INTRODUCTION:Data on hepatitis E virus (HEV) in Brazil are limited. We analyzed 15 years of HEV surveillance data in a major clinical laboratory in São Paulo, Brazil.METHODS:The seroprevalence of HEV of 2,271 patients subjected to anti-HEV tests from 1998 to 2013 were analyzed.RESULTS:HEV seroprevalence was 2.1%, and the anti-HEV IgM positivity rate was 4.9%. Six hepatitis E patients were identified.CONCLUSIONS:HEV seroprevalence and detection rates appear to have increased in recent years. Hepatitis E should be investigated further and included in the differential diagnosis of hepatitis in Brazil.

Caso 1/2013: homem de 69 anos com dor súbita em dorso e membro inferior direito e choque

MSM, homem, 69 anos, procurou atendimento médico por dor em dorso esquerdo e membro inferior direito. A radiografia de tórax revelou alargamento do mediastino. Estava em observação quando apresentou rebaixamento da consciência e choque. Foi observado enfisema subcutâneo em hemitórax esquerdo e abolição do murmúrio vesicular em base do mesmo pulmão. Foi feita a intubação orotraqueal e realizada drenagem de hemitórax esquerdo, com saída de líquido serossanguinolento. O ecocardiograma revelou ventrículo esquerdo (D/S): 44/29 mm; septo 12 mm; parede posterior 13 mm; discreta dilatação em raiz da aorta, presença de lâmina de dissecção e hematoma periaórtico. As valvas e pericárdio eram normais. O paciente foi transferido para o InCor. O exame físico (21 out 2004: 10h45) revelou paciente sedado, com intubação orotraqueal, com palidez cutânea, frequência cardíaca 90 bpm, pressão arterial 130 x 80 mmHg, drenagem torácica sanguinolenta do dreno tórax. Eletrocardiograma - frequência 90 bpm, ritmo sinusal, baixa voltagem no plano frontal e diminuição de voltagem em derivações esquerdas (fig. 1). A tomografia revelou enfisema subcutâneo bilateral, aorta torácica com contornos imprecisos na sua porção descendente (da artéria subclávia até porção média), colapso do pulmão esquerdo e grande coleção de características hemáticas em mesmo hemitórax e no mediastino médio e posterior. Pequeno pneumotórax à direita; pequeno derrame pleural à direita com alterações do parênquima subjacente. A análise do coração foi prejudicada pela presença do hemotórax. Durante a realização de tomografia apresentou ausência de pulsos, midríase, com assistolia, sem resposta às manobras de ressuscitação e faleceu (21 out 2011; 15h).
