RESUMO: Leishmaniose visceral causada por Leishmania infantum chagasi é uma zoonose endêmica em algumas regiões do Brasil. Este parasito necessita de reservatórios para a manutenção da infecção e a presença de cães em áreas urbanas é um fator importante para a manutenção e expansão da leishmaniose visceral canina (LVC). O objetivo deste estudo foi relatar o primeiro caso autóctone de LVC no município de Iguatama, na região Centro Oeste de Minas Gerais, cidade onde a LVC era tida como não existente. A infecção canina por Leishmania foi confirmada por três testes imunológicos para pesquisa de anticorpos: reação de imunofluorescência indireta (RIFI), teste rápido de imunocromatografia com plataforma dupla (DPP® LVC) e ensaio imunoenzimático (ELISA), e demonstração microscópica de amastigotas de Leishmania a partir de aposições de amostras de baço e de medula óssea corados pelo Giemsa. A espécie Leishmania infantum chagasi foi confirmada por diagnóstico molecular (PCR). Estudos estão sendo realizados com o objetivo de descrever a importância e a prevalência desta parasitose na região e os fatores associados com a transmissão.

ABSTRACT: Visceral Leishmaniasis by Leishmania infantum chagasi is an endemic zoonosis present in many areas of Brazil. This parasite needs reservoirs for maintenance of the infection and the presence of dogs in urban areas is a key factor for the spread of canine visceral leishmaniasis (CVL). The aim of this study was to report the first autochthonous case of CVL in the municipality of Iguatama, in west central region of Minas Gerais State. Dog infection by Leishmania infantum chagasi was confirmed in the municipality, previously considered as non-endemic area to CVL. The canine infection by Leishmania was confirmed by three immunological tests for antibodies: indirect immunofluorescence assay (IFA), rapid Dual Path Platform (DPP®) CVL immunochromatographic test, enzyme-linked immunosorbent assay (ELISA), and microscopic demonstration of Leishmania amastigotes in imprints of spleen and bone marrow stained by Giemsa. The species Leishmania infantum chagasi was confirmed by molecular diagnosis (PCR). Studies are being carried out, aiming to describe the importance and the prevalence of this disease in the region and factors associated with its transmission.

O artigo aborda a produção da política relacionada às Unidades de Pronto Atendimento (UPA) no estado do Rio de Janeiro, de 2007 a 2013, identificando as relações intergovernamentais nesse processo. Priorizou-se o contexto de formulação, os fatores que motivaram a entrada e a permanência das UPA na agenda estadual e a trajetória de implementação da política no estado. O estudo ancorou-se na literatura de definição de agenda e implementação de políticas públicas e em contribuições do institucionalismo histórico. A pesquisa envolveu a análise de documentos, de dados secundários e de 51 entrevistas com dirigentes estaduais e municipais. A confluência de fatores histórico-estruturais, político-institucionais e conjunturais explicam a prioridade das UPA na agenda governamental. Os resultados sugerem interdependência entre os governos, entretanto, problemas de coordenação federativa comprometem a integração dos diversos componentes da atenção às urgências no estado.

This article addresses policymaking related to Emergency Care Units (ECU) in the State of Rio de Janeiro between 2007 and 2013, duly identifying the relationships between the various levels of government in this process. It prioritized the context of policy formulation, the factors that motivated the inclusion and maintenance of ECUs on the state agenda and the process of how the policy was implemented in the state. The study was based on the literature that defines the agenda and implementation of public policies and on contributions from historic institutionalism. The research involved analysis of documents, secondary data, and 51 interviews with people in positions of authority in state and municipal governments. The priority given to ECUs in the government agenda was the result of a confluence of historical, structural, political and institutional factors, as well as the current context. The results of this study indicate the existence of interdependence between levels of government, however federal coordination problems have prejudiced the integration of the various components of emergency health care in the state.

OBJECTIVES: During the 2009 influenza A H1N1 pandemic, it became difficult to differentiate viral infections from other conditions in patients admitted to the intensive care unit. We sought to evaluate the behavior and diagnostic utility of procalcitonin, C-reactive protein and four other molecules in patients with suspected 2009 Influenza A H1N1 infection. METHODS: The serum levels of procalcitonin, C-reactive protein, tumor necrosis factor α, interferon γ, interleukin 1β, and interleukin 10 were tested on admission and on days 3, 5, and 7 in 35 patients with suspected 2009 H1N1 infection who were admitted to two ICUs. RESULTS: Twelve patients had confirmed 2009 influenza A H1N1 infections, 6 had seasonal influenza infections, and 17 patients had negative swabs. The procalcitonin levels at inclusion and on day 3, and the C-reactive protein levels on day 3 were higher among subjects with 2009 influenza A H1N1 infections. The baseline levels of interleukin 1b were higher among the 2009 influenza A H1N1 patients compared with the other groups. The C-reactive protein levels on days 3, 5, and 7 and procalcitonin on days 5 and 7 were greater in non-surviving patients. CONCLUSION: Higher levels of procalcitonin, C-reactive protein and interleukin-1β might occur in critically ill patients who had a 2009 H1N1 infection. Neither procalcitonin nor CRP were useful in discriminating severe 2009 H1N1 pneumonia. Higher levels of CRP and procalcitonin appeared to identify patients with worse outcomes.
