Ruptura espontânea do esôfago: síndrome de Boerhaave

Boerhaave's syndrome, the spontaneous rupture of the esophagus, is associated with a 35% death rate. Perforated esophagus is a surgical emergency; it is the most serious, and frequently the most rapidly lethal, perforation of the gastro-intestinal tract. Three cases of Boerhaave's syndrome are presented, with their variants and resolutions. Treatment and outcome are largely determined by the time of presentation. We reviewed our experience with esophageal perforations to determine the overall mortality and whether the time of presentation should influence management strategy.

Síndrome de Boerhaave: relato de caso

Spontaneous esophageal rupture carries high morbidity and mortality. The main prognostic factor is early diagnosis, before 12 hours, and appropriate treatment. This is a case report of a 41-years-old man with late esophageal rupture diagnosis treated successfully with transmediatinal esophagectomy and esophageal-gastric tube cervical anastomosis.

Breve história da otorrinolaringologia: otologia, laringologia e rinologia

O nariz, a garganta e o ouvido intrigam a humanidade desde os períodos mais remotos. Tratamentos laringológicos, rinológicos e otológicos, além de cirurgias, já eram praticados por médicos gregos, hindus e bizantinos. No século XX inovações clínicas e cirúrgicas foram incorporadas graças às novas técnicas anestésicas, aos antibióticos, à radiologia e às novas tecnologias. OBJETIVO E MÉTODO: Mostrar a evolução desta ciência ao longo dos tempos, reconhecendo figuras importantes da otologia, rinologia e laringologia por revisão em literatura. RESULTADO E CONCLUSÃO: O conhecimento das evoluções em anatomia, fisiologia, tratamentos clínicos e cirúrgicos, além das personalidades que conduziram a estes avanços é de grande importância para que a ciência médica evolua cada vez mais. A Otorrinolaringologia tem história muito rica, com importantes colaboradores e figuras de renome para a história da medicina. A especialidade foi uma das primeiras a utilizar anestesia local para realização de procedimentos, pioneira em tratamentos com próteses que recuperavam a audição e teve a primazia na utilização de microscópios em cirurgias. Poucas especialidades médicas sofreram tantas mudanças e desenvolvimentos científicos nestas últimas décadas quanto a Otorrinolaringologia que teve a vantagem de incorporar tecnologias na endoscopia, radiologia, microcirurgia e uso da informática.

Yield and nutrition of sunflower fertilized with sewage sludge stabilized by different processes

The different methods of sewage sludge stabilization modify their physical chemical and biological properties, altering its efficiency when applied in agriculture. The objective of this study was to evaluate the nutrient levels in soil and the yield of sunflower fertilized with sewage sludge stabilized by different processes. The experiment was conducted in Cambisol, with the treatments: control (without fertilization), fertilization with sewage sludge solarized, composted, vermicomposted, limed and chemical fertilizer recommended for sunflower crop. The experimental design a randomized block with four replications. The different methods of sewage sludge treatment did not affect the yield; however, the application of sewage sludge, regardless the stabilization process adopted, was more effective than chemical fertilizer and the control treatment. Overall, fertilization with limed sewage sludge provided higher soil nutrients concentrations, while treatments with composted and vermicomposted sewage sludge showed higher levels of nutrients in the plant.

Sistema de informações para acompanhamento, controle e auditoria em saúde pública

Este artigo apresenta alternativas para a gestão dos recursos destinados à saúde pública, por meio de um sistema de informações para os programas de diabetes e hipertensão e resulta do interesse em analisar a efetividade dos programas destinados aos portadores de doenças crônico-degenerativas. As questões analisadas foram focadas em fatores que traduzem a efetividade das ações desenvolvidas, isto é, a capacidade de gerar resultados a partir dos investimentos feitos. Isso ocorreu por meio de um modelo proposto para análise do resultado, mediante o estabelecimento de um indicador que consolidou três frentes de resultado, o número de óbitos, internações e atendimentos ambulatoriais. O índice estabelecido para análise da efetividade derivou em um indicador de custos. Como percurso metodológico foi aplicado o modelo teórico de planejamento e controle de produção (PCP) elaborado por Erdmann (1998), que considera sete etapas para a consolidação de informações fragmentadas em um sistema.

Seroepidemiology of hepatitis a and b in two urban communities of Rio de Janeiro, Brazil

Hepatitis B markers were determined in 397 individuals from Niterói and 680 from Nova Iguaçu and prevalences of 9.1% (1.0% of HBsAg and 8.1% of anti HBs) and 11.1% (1.8% of HBsAg and 9.3% of antiHBs) were found, respectively. The comparative prevalence of both markers in relation to age showed a higher prevalence of HBsAg in the group 21-50 years old. Considering the antiHBs antibody, it was demostrated a gradual increase with age, reaching 14.9% in Niterói and 29.1% in Nova Iguaçu in individuals over 51 years old. For hepatitis A, in 259 samples from Niterói, equally distributed by age groups, an overall prevalence of 74.5% of anti-HAV antibodies was found. This prevalence increases gradually reaching 90.0% at age over thirty. In 254 samples from Nova Iguaçu analysed, a prevalence of 90.5% of antibodies was encountered when the same criteria of distribution of samples were used. This level of prevalence reached 90.0% already in the age over ten years old. The tests were performed by enzyme immunoassay with reagents prepared in our laboratory.

A serological investigation of rotavirus infections in a shanty town population in Rio de Janeiro

The presence of antibodies against rotavirus was investigated by enzyme immunosorbent assay (ELISA) in two distinct groups of children living in a shanty town in Rio de Janeiro. One hundred and thirty six plasma samples were randomly collected from children of 0 to 33 months (first group) and 255 serum samples were collected from other 85 children at ages of 2, 6 and 9 months (second group). A high percentage of antibodies were found in the newborn children and this rate decreased progressively until the age of 11 months, after which it increased again. At the age of 7 months, geometric mean antibody titers increased indicating that infection had occurred.

Use of MAC-ELISA for evaluation of yellow fever vaccination

An evaluation of the IgM antibody immune response against yellow fever using strain 17D was carried out by MAC-ELISA and PRNT. The results showed an agreement of 97% between both tests and the authors conclude that MAC-ELISA can be used as a specific and sensitive asssay to replace the PRNT for detecting yellow fever antibodies in human sera, after vaccination programs.

Dengue epidemic in the state of Rio de Janeiro, Brazil: virological and epidemiological aspects

Laboratorial studies were carried out on 3178 patients with signs and symptoms suggestive of dengue infection from April 1986 to December 1987 in the State of Rio de Janeiro, Brazil. The epidemic had two peaks following the first virus isolation and affected the inhabitants of 17 counties. Both sex and all age groups were affected. Dengue virus type 1 was isolated from 1039 sera and the number of confirmed cases was increased to 1874 (59%) by MAC-ELISA. Isolation rate confirmed cases reached 80% in the specimens obtained until the 4th day after the onset of disease and viraemia ranged from 10 3.0 to 10(8.5) TCID50/ml.

Dengue type 2 outbreak in the south of the State of Bahia, Brazil: laboratorial and epidemiological studies

During March 1994 cases of a exanthematic acute disease were reported in the municipalities of Itagemirim, Eunápolis and Belmonte, state of Bahia. Dengue fever was confirmed by serology (MAC-ELISA) and by dengue virus type 2 isolation, genotype Jamaica. Signs and symptoms of classic dengue fever were observed with a high percentual of rash (73.8%) and pruritus (50.5%). Major haemorrhagic manifestations were unfrequent and only bleeding gum was reported. Dengue virus activity spreaded rapidly to important tourism counties like Porto Seguro, Ilhéus, Santa Cruz de Cabrália, Prado, Alcobaça and others, representing a risk for the spreading of dengue virus into the country and abroad.
