Leprosy frequency in the world, 1999-2010

In 1991, the World Health Organization (WHO) committed to reducing the prevalence of leprosy to below 1 in 10,000 inhabitants by 2000. Significant improvements in leprosy control have occurred, but leprosy remains a public health problem in many countries due to its high incidence and rate of transmission. This paper reviews data published by the WHO in the years 2000, 2005 and 2010. These data sets included 148 countries or territories that reported to the WHO at least once. Only four countries reported higher prevalence rates in 2010 than in 2000 and eight reported higher case detection rate (CDR) in 2009 than in 1999. Prevalence rate reductions were greater for the first five-year period examined, while CDR reductions were greater in the second five-year period. Thirty-six countries and territories reported at least one prevalence value higher than 1 per 10,000 inhabitants and 32 reported at least one CDR value higher than 9 per 100,000 inhabitants. A total of 39 countries fit at least one of these criteria and all were located in tropical regions.

Detection and differentiation of Cryptosporidium by real-time polymerase chain reaction in stool samples from patients in Rio de Janeiro, Brazil

This study reports the first genetic characterisation of Cryptosporidium isolates in Brazil using real-time polymerase chain reaction (RT-PCR). A total of 1,197 faecal specimens from children and 10 specimens from human immunodeficiency virus-infected patients were collected between 1999-2010 and screened using microscopy. Forty-eight Cryptosporidium oocyst-positive isolates were identified and analysed using a generic TaqMan assay targeting the 18S rRNA to detect Cryptosporidium species and two other TaqMan assays to identify Cryptosporidium hominis and Cryptosporidium parvum. The 18S rRNA assay detected Cryptosporidium species in all 48 of the stool specimens. The C. parvum TaqMan assay correctly identified five/48 stool samples, while 37/48 stool specimens were correctly amplified in the C. hominis TaqMan assay. The results obtained in this study support previous findings showing that C. hominis infections are more prevalent than C. parvum infections in Brazil and they demonstrate that the TaqMan RT-PCR procedure is a simple, fast and valuable tool for the detection and differentiation of Cryptosporidium species.

Dinâmica dos financiamentos habitacionais nos municípios do Rio Grande do Sul de 2006 a 2010: uma avaliação do Programa "Minha Casa, Minha Vida"

O déficit habitacional no Brasil é um problema crônico, apesar dos diversos programas implementados a fim de solucionar essa questão. Este estudo objetiva analisar os elementos impulsionadores dos financiamentos habitacionais e seus impactos, em termos regionais, no estado do Rio Grande do Sul, no período de 2006 a 2010, por meio da combinação de três procedimentos: o método estrutural-diferencial, a técnica de krigagem e a regressão espacial. Os resultados indicam que as faixas de crédito que mais cresceram foram as de valor intermediário, que os municípios de menor nível de renda foram os mais beneficiados com o crédito e que houve um deslocamento dos valores dos imóveis para as regiões menos valorizadas, reduzindo as desigualdades regionais. Ou seja, o programa "Minha Casa, Minha Vida" intensificou o volume de crédito, mas não alterou os aspectos estruturais dos financiamentos.

Letalidade e complicações da cirurgia de revascularização miocárdica no Rio de Janeiro, de 1999 a 2003

FUNDAMENTO: A cirurgia de revascularização do miocárdio (RVM) é um procedimento consolidado no tratamento das doenças isquêmicas do coração (DIC), requerendo constante avaliação. OBJETIVO: Avaliar a qualidade na RVM, através das características clínicas dos pacientes, taxas de letalidade até um ano após a alta hospitalar, causas básicas de morte e complicações pós-operatórias, em quatro hospitais públicos do Município do Rio de Janeiro, de 1999 a 2003. MÉTODOS: Foram selecionados aleatoriamente prontuários de pacientes submetidos à RVM. Informações sobre características clínicas, complicações e óbitos foram coletadas retrospectivamente dos prontuários e das declarações de óbitos. As taxas de letalidade foram estimadas nos períodos intra-hospitalar e até um ano pós-alta. RESULTADOS: As prevalências das características pré-operatórias foram: mulher: 31,9%, hipertensão arterial: 90,7%, dislipidemia: 67,4%, diabete: 37,2%, tabagismo: 22,9%, obesidade: 18,3%, doença pulmonar obstrutiva crônica: 8,2%, acidente vascular encefálico prévio: 5,8%, arteriopatia extracardíaca: 12,7%, elevação da creatinina: 4,1%, estado crítico pré-operatório: 3,7%, infarto agudo do miocárdio recente: 23,5%, angina instável: 40,8%, síndrome coronariana aguda: 50,0%, RVM prévia: 2,4%, disfunção ventricular esquerda: 27,3%, lesão de tronco da coronária esquerda: 3,9% e associada com lesão em outro sistema: 19,8%. As taxas de letalidade nos hospitais variaram de 7,0% a 14,3% no período intra-hospitalar e de 8,5% a 20,2% até um ano pós-alta. As DIC representaram as causas de mais de 80% dos óbitos. O grupo de complicações pós-operatórias mais frequente foi de hemorragia ou baixo débito pós-procedimento. Sessenta por cento dos óbitos apresentaram cinco ou mais complicações enquanto que 40% dos sobreviventes nenhuma. CONCLUSÃO: As taxas de letalidade e de complicações foram elevadas. Mesmo nos sobreviventes as complicações foram mais frequentes do que o esperado.

Evolution of Cardiovascular Diseases Mortality in the Counties of the State of Rio de Janeiro from 1979 to 2010

Background: Cardiovascular Diseases (CVD) are the leading cause of death in Brazil. Objective: To estimate total CVD, cerebrovascular disease (CBVD), and ischemic heart disease (IHD) mortality rates in adults in the counties of the state of Rio de Janeiro (SRJ), from 1979 to 2010. Methods: The counties of the SRJ were analysed according to their denominations stablished by the geopolitical structure of 1950, Each new county that have since been created, splitting from their original county, was grouped according to their former origin. Population Data were obtained from the Brazilian Institute of Geography and Statistics (IBGE), and data on deaths were obtained from DataSus/MS. Mean CVD, CBVD, and IHD mortality rates were estimated, compensated for deaths from ill-defined causes, and adjusted for age and sex using the direct method for three periods: 1979–1989, 1990–1999, and 2000–2010, Such results were spatially represented in maps. Tables were also constructed showing the mortality rates for each disease and year period. Results: There was a significant reduction in mortality rates across the three disease groups over the the three defined periods in all the county clusters analysed, Despite an initial mortality rate variation among the counties, it was observed a homogenization of such rates at the final period (2000–2010). The drop in CBVD mortality was greater than that in IHD mortality. Conclusion: Mortality due to CVD has steadily decreased in the SRJ in the last three decades. This reduction cannot be explained by greater access to high technology procedures or better control of cardiovascular risk factors as these facts have not occurred or happened in low proportion of cases with the exception of smoking which has decreased significantly. Therefore, it is necessary to seek explanations for this decrease, which may be related to improvements in the socioeconomic conditions of the population.

OBJETIVO: Avaliar o impacto das ações de vigilância sanitária sobre a qualidade das imagens mamográficas no Estado da Paraíba. MATERIAIS E MÉTODOS: Em 17 serviços de mamografia do Estado foi exigida pela Vigilância Sanitária a aplicação de testes de qualidade de acordo com a Portaria 453/98 do Ministério da Saúde. Foram utilizados simuladores específicos de mama para a avaliação da qualidade. Uma pontuação foi utilizada para classificar a qualidade de imagem de cada serviço. Considerou-se como critério mínimo e imprescindível o atendimento de uma pontuação 70% dos itens de qualidade. Entre os anos de 1999 e 2003 foi analisada a pontuação de qualidade de imagens desses serviços. Foi realizado um programa de educação de controle de qualidade de imagem pela Vigilância Sanitária da Paraíba. RESULTADOS: Os percentuais de serviços de mamografia que atingiram critério imprescindível de qualidade foram: 1999 (25%), 2000 (77%), 2001 (82%) e 2003 (81%). CONCLUSÃO: Os resultados obtidos demonstram haver uma significativa evolução na qualidade das imagens diagnósticas produzidas pelos serviços de mamografia após a implantação de programas de controle de qualidade da imagem.

Rendering peacekeeping instrumental? The Brazilian approach to United Nations peacekeeping during the Lula da Silva years (2003-2010)

The article analyses how Brazilian state actions and policies regarding peace operations during the Presidency of Lula da Silva relate to the country's positions and attitudes towards United Nations peacekeeping. It argues that the inconsistencies identified on the Brazilian positions reflect the lack of a clear strategic horizon guiding the country's participation in UN peacekeeping, which consequentially hinders the country emergence as a great power.
