AimThe objective of this study was to critically analyze data of the National Notification System for Adverse Events and Technical Complaints (Notivisa) related to central venous catheters, through an evaluation of the description of notifications recorded between 2006 and 2009. MethodsNotifications were categorized and evaluated to: (i) determine the number of adverse events and technical complaints, (ii) verify compliance with the classification criteria defined by the legislation, (iii) reclassify notifications, when necessary, in order for them to fit in with the legal definitions, (iv) verify registered companies in Brazil, (v) quantify the notifications according to the registered company and product lot, and (vi) identify the country of original of the notified product. Microsoft Excel(r) 2010 was used to categorize and systematize the data. ResultsSome conceptual errors and incomplete records were found. Altogether, 228 notifications of technical complaints and 119 of adverse events were identified. Some notifications on guidewires and broken catheters were reported which led to the necessity of duplicating some medical procedures and to the occurrence of lesions/lacerations of vessels and tissue injury. Forty-seven percent of companies presented at least one notification in Notivisa and in all, 38 product lots had more than one notification. ConclusionThese data support a necessity for cooperation between all entities of the National Health Surveillance System to check compliance of this type of product and to properly report adverse events and technical complaints. It is also important to incorporate minimum standards for the management of technologies in health services, including in the acquisition of products and training of staff.
BackgroundSerum lactate dehydrogenase is a non-specific marker for lymphoma whose prognostic significance is well established for both indolent and aggressive lymphomas at the time of diagnosis. The performance characteristics of this enzyme in predicting relapse in patients with diffuse large B-cell lymphoma has not been well studied. MethodsThis study compared serum lactate dehydrogenase levels in 27 patients with diffuse large B-cell lymphoma who relapsed after sustaining a complete response versus 87 patients who did not relapse. For relapsed patients, the serum lactate dehydrogenase level at relapse was compared with the level three months before (considered baseline). For non-relapsed patients, the last two levels during follow-up were compared. For statistical analysis the T-test was used to compare differences in mean values between groups. The sensitivity, specificity, positive and negative predictive values for serum lactate dehydrogenase in detecting relapse compared to confirmatory imaging were calculated. ResultsAt relapse, only 33% patients had increases in serum lactate dehydrogenase above the upper limit of normal. The mean increase was 1.2-fold above the upper limit of normal for relapsed vs. 0.83 for those who did not relapse (p-value = 0.59). The mean increase in serum lactate dehydrogenase, from baseline, was 1.1-fold in non-relapsed vs. 1.3 in relapsed patients (p-value = 0.3). The likelihood ratio of relapse was 4.65 for patients who had 1.5-fold increases in serum lactate dehydrogenase above baseline (p-value = 0.03). The sensitivity, specificity, positive and negative predictive values of 1.5-fold increases for detecting relapse, compared to clinical and imaging findings were 0.18, 0.95, 0.55, and 0.79, respectively. ConclusionA 1.5-fold increase in serum lactate dehydrogenase, over a period of 3 months, is associated with increased likelihood of relapse from diffuse large B-cell lymphoma.
Informe Epidemiológico do SUS 2002; 11(2) : 61 -68. (neonatal and post-neonatal mortality), Swaroop-Uemura indicator, and Guedes indicator (adapted by Pereira). Analysis was performed comparing two periods: 1990 to 1994 and 1995 to 1999 in A garantia de demarcação de terras indígenas é fator básico para que se garanta a produção e reprodução dos grupos indígenas, assim como sua integridade física, material e de sua tradições, fazendo com que cesse o processo de despopulação, e incremente a recuperação populacional. Esse fato já vem sendo observado no Estado do Paraná, que, no período de 1975 a 1997, registrou um aumento da população indígena -de cerca de 2.500 para aproximadamente 9.000. Para que se preserve também a saúde dos povos indígenas, é necessário rever a forma de assistência prestada, considerando as diferenças culturais e epidemiológicas, além de incentivar que os próprios índios tenham parcela de Apesar de haver predomínio de uma determinada etnia em cada aldeia, observa-se também miscigenação, com alta proporção de mestiços em todas elas. Resumo Com o objetivo de conhecer a situação de saúde de índios que vivem no norte do Paraná, realizou-se estudo descritivo, em que são analisados os seguintes indicadores: coeficiente de mortalidade infantil e seus componentes (mortalidade neonatal e pós-neonatal), indicador de Swaroop-Uemura e indicador de Guedes adaptado por Pereira, no período de 1990 a 1999. A análise foi feita, comparando dois períodos: 1990-94 e 1995-99, para evitar flutuações aleatórias devido ao número pequeno de casos. Os dados foram obtidos em livros de registros de nascimentos e óbitos dos índios, existentes em cada reserva indígena, bem como em declarações de nascidos vivos e declarações de óbitos quando esses eventos ocorreram em hospitais. Para evitar perdas ou duplicidade nas informações, esses dados foram ainda comparados com os relatórios enviados à Fundação Nacional do Índio (FUNAI). Os resultados revelaram queda do nível de saúde da população indígena dessa região, com piora de todos os indicadores e aumento da mortalidade prematura, o que sugere a piora das condições de vida e a necessidade de rever as estratégias nas ações ligadas à assistência à saúde desses povos. Palavras-ChaveTodas as aldeias são próximas às cidades a que pertencem (de 3 a 30km) e possuem fácil acesso, pois as estradas apresentam boas condições, facilitando o transporte por ônibus e caronas ou deslocamentos a pé.Um outro ponto a ser levantado é que os modos de vida desses povos são muito semelhantes entre si, inclusive do ponto de vista econômico. Cultivam produtos de subsistência (arroz, milho e feijão) e deslocam-se com muita freqüência para centros urbanos para comercializar artesanatos, orquídeas e outros produtos naturais. ResultadosPara o coeficiente de mortalidade infantil, observou-se uma piora no segundo período (de 57 para 79,9 por mil nascidos vivos). Ao se decompor o coeficiente de mortalidade infantil em coeficientes neonatal e pós-neonatal, nota-se que o componente neonatal foi o que mai...
