Surveillance Programme for Healthcare Associated Infections in the State of São Paulo, Brazil. Implementation and the first three years' results

Governmental programmes should be developed to collect and analyse data on healthcare associated infections (HAIs). This study describes the healthcare setting and both the implementation and preliminary results of the Programme for Surveillance of Healthcare Associated Infections in the State of São Paulo (PSHAISP), Brazil, from 2004 to 2006. Characterisation of the healthcare settings was carried out using a national database. The PSHAISP was implemented using components for acute care hospitals (ACH) or long term care facilities (LTCF). The components for surveillance in ACHs were surgical unit, intensive care unit and high risk nursery. The infections included in the surveillance were surgical site infection in clean surgery, pneumonia, urinary tract infection and device-associated bloodstream infections. Regarding the LTCF component, pneumonia, scabies and gastroenteritis in all inpatients were reported. In the first year of the programme there were 457 participating healthcare settings, representing 51.1% of the hospitals registered in the national database. Data obtained in this study are the initial results and have already been used for education in both surveillance and the prevention of HAI. The results of the PSHAISP show that it is feasible to collect data from a large number of hospitals. This will assist the State of São Paulo in assessing the impact of interventions and in resource allocation. (C) 2010 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.

Serological Evidence of Bovine Herpesvirus 5 (BoHV-5) in Cattle at the Colombia's Eastern Plains

Several diseases involve the nervous system of cattle, among which infections with Rabies Virus and Bovine Herpes Virus 5 (BoHV-5) are noteworthy. In order to detect seropositive animals to BoHV-5, 156 Brahman-Zebu bovines blood samples from Colombia's eastern plains were analyzed through seroneutralization assay; the area has a history of animals dying with nervous symptoms and which rule out the disease of rabies. All animals were over one year old and randomly selected from two different herds reporting no vaccination for infectious bovine rhinotracheitis in a period exceeding one year. Results indicated seropositivity for BoHV-5 in 91 cases (58.4%), of which 88 were also seropositive for bovine herpes virus 1 (BoHV-1), while 41 were seronegative for both agents. 22/64 seronegative cases for BoHV-5 were seropositive for BoHV-1 and 2/43 seronegative cases for BoHV-1 were seropositive for BoHV-5, and consequently, these animals could be only infected by encephalitis herpes virus. With these initial findings, emphasis its placed on the need establish the true impact of the disease in Colombia and proposes the epidemiological surveillance of cattle in the region studied in order to establish mechanisms for control of viral infection.

Acquired immunodeficiency syndrome in Brazil

Aim. To describe the acquired immunodeficiency syndrome (AIDS) epidemic in Brazil and analyze the impact of federal government measures addressing the problem since its onset.Method. Retrospective review of AIDS epidemic data from its onset in 1980 up to the last published data in June 2001.Results. AIDS was first reported in Brazil in 1980. By 1988, all 27 Brazilian states had diagnosed cases, and until June 2000 more than half of Brazilian municipalities had recorded at least one case of the disease. The AIDS incidence reached its peak between 1996 and 1997 (14.7 per 100,000 population), and then declined between 1998 and 2000 to 9 per 100,000 population. In the last two decades, the proportion of deaths has been also significantly reduced. These were not random events, but reflected the efficiency of the program implemented by the Brazilian Health Ministry's Coordination on Sexually Transmitted Diseases and AIDS. The program includes an epidemiological surveillance modeling system, which records cases from several regular epidemiological bulletins; national network of diagnosis and monitoring of HIV-infected individuals (ill or not); highly active antiretroviral therapy available free to all patients; mother-infant protection program; educational programs on condom use; the introduction of the female condom; development of AIDS studies in different areas to provide practical solutions; constant preoccupation about drug costs accounting for the patent breaking; and national production of many drugs currently in use.Conclusion. Well-planned and implemented national program against AIDS can significantly reduce the burden of this disease to the population.

Acidente com material perfurocortante entre profissionais de enfermagem de um hospital universitário

Os riscos ocupacionais a que os profissionais da equipe de enfermagem estão sujeitos no desempenho de suas funções são consideráveis. Assim estabeleceu-se como objetivo deste estudo analisar os acidentes perfurocortantes no período de 2002 a 2006, envolvendo a equipe de enfermagem de um hospital universitário, para compreender o contexto em que ocorrem. A utilização destas informações pode ser ferramenta de prevenção. Estudo descritivo, retrospectivo quantitativo e qualitativo. Na análise quantitativa foi utilizada estatística descritiva e na qualitativa o discurso do sujeito coletivo. Por meio das fichas de notificação do Núcleo de Vigilância Epidemiológica do Hospital, foi possível identificar acidentes do gênero no período pesquisado. Entrevistas foram direcionadas às vítimas de acidentes que tiveram como paciente-fonte portador de Síndrome da Imunodeficiência Adquirida/ Vírus da Imunodeficiência Humana, hepatite B e C. Os achados demonstraram que ainda persiste um grau significativo do desconhecimento ou banalização dos acidentes entre profissionais da saúde.

Soroprevalência da arterite viral equina em mesorregiões paulistas entre 2007 e 2008

This study investigated the occurrence of equine arteritis virus antibodies using neutralization test in 1,400 horses from Campinas and macro metropolitan paulista mesoregions located at São Paulo State, between 2007 and 2008. Eighty (5.7%) samples showed antibodies to virus (titers from 4 to 4,096). Among the 42 cities, 15 (35.7%) presented at least one seropositive animal to equine arteritis virus. of the 238 farms analyzed 41 showed at least one seropositive animal. The occurrence was higher in sport horses like jumping horses, Quarter horses and was similar for female and male. The rate of seropositive was higher in animals older than 24 months of age. These results suggest the virus circulation among horse population in studied farms, and the need for continuing epidemiological surveillance studies.

Avaliação do teste do anel em leite na vigilância epidemiológica da brucelose bovina em rebanhos e em laticínios

Analisaram-se 464 amostras individuais de leite e 54 amostras de leite de latões, oriundos de leite dos mesmos animais, por meio do teste do anel do leite (TAL) visando à sua aplicação no diagnóstico individual e de rebanhos da brucelose bovina. Foram também avaliadas 464 amostras de soro sangüíneo por meio de provas do antígeno tamponado acidificado (ATA), soroaglutinação lenta em tubos (SAL) e 2-mercaptoetanol (2-ME), todas para brucelose. Cento e vinte e três amostras (26,5%) testadas pelo TAL apresentaram resultados positivos. Dessas, 30 resultaram positivas ao ATA, 28 ao ATA, à SAL e ao 2-ME e 18 à SAL. Das amostras positivas ao TAL, 95 pertenciam a animais sorologicamente negativos ao 2-ME, caracterizando 77,2% (95/123) das reações falso-positivas; dos resultados negativos ao TAL, 4 pertenciam a animais sorologicamente positivos, caracterizando 1,2% (4/341) de reações falso-negativas no TAL individual. Das 54 amostras de leite de latões analisadas pelo TAL, 17 foram consideradas positivas, das quais uma foi caracterizada como falso-positivo, pois todos os animais que a compunham foram negativos ao 2-ME. de 37 latões considerados negativos ao TAL, três continham leite de animais positivos ao 2-ME, caracterizando 8,1% de falso-negativos. O TAL individual demonstrou elevado percentual de resultados falso-positivos, enquanto o TAL em amostras de leite obtidas em latões detectou 84,2% de latões contaminados e 75% de rebanhos infectados.

Análise geoestatística de casos de hanseníase no Estado de São Paulo, 1991-2002

OBJETIVO: Analisar o padrão espacial da ocorrência dos casos de hanseníase para identificar áreas com probabilidade de riscos de transmissão da doença. MÉTODOS: Estudo ecológico, tendo como unidade de análise os municípios do Estado de São Paulo georreferenciados em seus centróides. A fonte de dados utilizada foi o banco informatizado dos casos de hanseníase notificados do Centro de Vigilância Epidemiológica do Estado de São Paulo, no período de 1991 a 2002. Utilizou-se de técnicas de geoestatística para a detecção das áreas de probabilidade de risco para hanseníase e quantificação da dependência espacial dos casos. RESULTADOS: Detectou-se o alcance de dependência espacial de 0,55 graus de coordenadas georreferenciadas, correspondendo aproximadamente a 60 km. As principais áreas de probabilidade de risco encontradas foram as regiões nordeste, norte e noroeste do Estado. CONCLUSÕES: A verificação de áreas com probabilidades de riscos de casos de hanseníase, utilizando-se a análise da dependência espacial, pode ser ferramenta útil para avaliar a situação de saúde e planejar alocação de recursos.

Lutzomyia longipalpis (Diptera, Psychodidae) em Cuesta Basáltica, na bacia hidrográfica do Rio Corumbataí, Região Centro-leste do Estado de São Paulo

A incidência das leishmanioses tegumentar e visceral americanas, em especial esta última (LVA), em hospedeiros caninos e humanos, encontra-se em crescente processo de expansão no Estado de São Paulo. Para a vigilância epidemiológica dessas endemias, torna-se fundamental o conhecimento da distribuição e da ecologia das diferentes espécies da fauna flebotomínea vetoras. Assim, a divulgação de novos encontros de seus vetores, sobretudo da Lutzomyia longipalpis, o principal vetor da LVA, é fundamental para apontar novas áreas de risco para a transmissão dessas doenças. Neste estudo, capturas de flebotomíneos foram realizadas em ambiente domiciliar, peridomiciliar e de mata, em diferentes localidades rurais dos municípios de Ipeúna e Itirapina, entre outubro de 2001 e fevereiro de 2004. Foram utilizadas armadilhas luminosas automáticas do tipo CDC, das 18h às 8h, em 14 noites, resultando 420 horas de exposição. Foram capturados 177 flebotomíneos pertencentes a doze espécies. A espécie mais abundante, Nyssomyia neivai, apontada como a principal vetora de LTA no Estado, contribuiu com 85,4% dos espécimes capturados em Ipeúna. O encontro de Lutzomyia longipalpis em uma caverna em Itirapina, aponta para o risco de estabelecimento da LVA na área e a necessidade de mais estudos locais sobre sua ecologia, sobretudo em relação à ocupação de ambientes antrópicos.

An integrated database on ticks and tick-borne zoonoses in the tropics and subtropics with special reference to developing and emerging countries

Tick-borne zoonoses (TBZ) are emerging diseases worldwide. A large amount of information (e.g. case reports, results of epidemiological surveillance, etc.) is dispersed through various reference sources (ISI and non-ISI journals, conference proceedings, technical reports, etc.). An integrated database-derived from the ICTTD-3 project (http://www.icttd.nl)-was developed in order to gather TBZ records in the (sub-)tropics, collected both by the authors and collaborators worldwide. A dedicated website (http://www.tickbornezoonoses.org) was created to promote collaboration and circulate information. Data collected are made freely available to researchers for analysis by spatial methods, integrating mapped ecological factors for predicting TBZ risk. The authors present the assembly process of the TBZ database: the compilation of an updated list of TBZ relevant for (sub-)tropics, the database design and its structure, the method of bibliographic search, the assessment of spatial precision of geo-referenced records. At the time of writing, 725 records extracted from 337 publications related to 59 countries in the (sub-)tropics, have been entered in the database. TBZ distribution maps were also produced. Imported cases have been also accounted for. The most important datasets with geo-referenced records were those on Spotted Fever Group rickettsiosis in Latin-America and Crimean-Congo Haemorrhagic Fever in Africa. The authors stress the need for international collaboration in data collection to update and improve the database. Supervision of data entered remains always necessary. Means to foster collaboration are discussed. The paper is also intended to describe the challenges encountered to assemble spatial data from various sources and to help develop similar data collections.

Epidemiology of the Cnidarian Physalia physalis stings attended at a health care center in beaches of Adicora, Venezuela

Stings caused by jellyfish and jellyfish-like colonies are common all around the world, with serious manifestations and occasional deaths reported in some countries. Between December 2006 and 2007, epidemiological, clinical and treatment aspects of stings caused by the Portuguese man-of-war (Physalia physalis) in 59 patients consulting the ambulatory emergency in Adicora, Falcon State, Venezuela, were studied. Most of the stings occurred in males (59%) preschool and school-aged children (49%), visitors from other areas of the country (92%) during holidays when bathing or diving at the beach (97%). Injuries presented linear erythematous plaques at the point of contact with the animal, located in several anatomical sites. Most clinical manifestations observed were: intense burning pain, urticaria, erythema and inflammation (100%), as well dyspnea with laryngeal edema and fever (19%). Patients were treated with topical drugs, including antihistamine and antipyretic drugs, but also with systemic hydrocortisone. P. physalis stings in Adicora appeared to have a seasonal pattern, with systemic complications potentially life-threatening. Thus, epidemiological surveillance program is recommended, particularly in travelers. (C) 2012 Elsevier Ltd. All rights reserved.

Caso alóctone de leishmaniose visceral canina, no município de Campo Mourão, Paraná, Brasil

This report aims to describe the first case allochthonous of visceral leishmanisasis (VL) in the municipality of Campo Mourao, Parana, Brazil, in a canine, Boxer breed, with eye and skin lesions, lymphadenomegaly and splenomegaly, attended at Veterinary Hospital at the Faculdade Integrado de Campo Mourao, after residing in the city of Campo Grande, Mato Grosso do Sul. The diagnosis of the disease was based on direct observation of amastigotes of Leishmania spp., in popliteal lymph nodes, suggesting that a case of VL, since the animal came from an endemic area for the disease. The migration of infected dogs from endemic regions to areas unaffected becomes a problem for public health, since it may allow the installation of new outbreaks by encouraging the spread of disease throughout the country.
