Estado de imunização contra a hepatite B em médicos residentes de um hospital do Recife

Objetivo: Estimar a frequência do estado imune contra a hepatite B e a situação vacinal em residentes do Hospital Barão de Lucena. Métodos: Aplicação de questionário e dosagem sérica da titulação anti-HBs em 53 residentes. Considerada imunidade a titulação a partir de 10 mUI/ml. Resultados: 83% dos residentes apresentaram imunidade contra a hepatite B. 100% receberam alguma dose da vacina, dos quais 75,5% receberam 3 ou mais doses, 11,3% receberam 2 doses e 13,2% não sabiam informar quantas doses receberam. 96,2% consideraram como obrigatória a recomendação da vacinação para médicos ou estudantes de medicina. Conclusão: Apesar de todos os residentes  referirem ter tomado alguma dose da vacina, muitos não checaram se houve soro conversão, mesmo os que não receberam o esquema completo. Torna-se necessário a realização de medidas educativas em relação à prevenção de acidentes ocupacionais e de infecção contra a hepatite B

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt

Bronchiolitis associated with exposure to artificial butter flavoring in workers at a cookie factory in Brazil

OBJECTIVE: To report the cases of four patients with bronchiolitis caused by exposure to artificial butter flavoring at a cookie factory in Brazil. METHODS: We described the clinical, tomographic, and spirometric findings in the four patients, as well as the lung biopsy findings in one of the patients. RESULTS: All four patients were young male nonsmokers and developed persistent airflow obstruction (reduced FEV1/FVC ratio and FEV1 at 25-44% of predicted) after 1-3 years of exposure to diacetyl, without the use of personal protective equipment, at a cookie factory. The HRCT findings were indicative of bronchiolitis. In one patient, the surgical lung biopsy revealed bronchiolitis obliterans accompanied by giant cells. CONCLUSIONS: Bronchiolitis resulting from exposure to artificial flavoring agents should be included in the differential diagnosis of airflow obstruction in workers in Brazil.OBJETIVO: Relatar quatro casos de bronquiolite decorrente de exposição a aroma artificial de manteiga em uma fábrica de biscoitos no Brasil. MÉTODOS: Descrevemos os achados clínicos, espirométricos e tomográficos nos quatro pacientes, assim como achados de biópsia pulmonar em um dos pacientes. RESULTADOS: Os quatro pacientes eram homens jovens, não fumantes, e desenvolveram obstrução persistente ao fluxo aéreo (relação VEF1/CVF reduzida e VEF1 de 25-44% do previsto) após 1-3 anos de exposição a diacetil, sem a utilização de equipamentos de proteção individual, em uma fábrica de biscoitos. A TCAR mostrou achados indicativos de bronquiolite. Em um paciente, a biópsia pulmonar cirúrgica mostrou bronquiolite obliterante associada a células gigantes. CONCLUSÕES: A bronquiolite decorrente de exposição a flavorizantes artificiais deve ser considerada em trabalhadores com obstrução ao fluxo aéreo no Brasil

Validation of a case definition for leptospirosis diagnosis in patients with acute severe febrile disease admitted in reference hospitals at the State of Pernambuco, Brazil

INTRODUCTION: Leptospirosis is often mistaken for other acute febrile illnesses because of its nonspecific presentation. Bacteriologic, serologic, and molecular methods have several limitations for early diagnosis: technical complexity, low availability, low sensitivity in early disease, or high cost. This study aimed to validate a case definition, based on simple clinical and laboratory tests, that is intended for bedside diagnosis of leptospirosis among hospitalized patients. METHODS: Adult patients, admitted to two reference hospitals in Recife, Brazil, with a febrile illness of less than 21 days and with a clinical suspicion of leptospirosis, were included to test a case definition comprising ten clinical and laboratory criteria. Leptospirosis was confirmed or excluded by a composite reference standard (microscopic agglutination test, ELISA, and blood culture). Test properties were determined for each cutoff number of the criteria from the case definition. RESULTS: Ninety seven patients were included; 75 had confirmed leptospirosis and 22 did not. Mean number of criteria from the case definition that were fulfilled was 7.8±1.2 for confirmed leptospirosis and 5.9±1.5 for non-leptospirosis patients (p<0.0001). Best sensitivity (85.3%) and specificity (68.2%) combination was found with a cutoff of 7 or more criteria, reaching positive and negative predictive values of 90.1% and 57.7%, respectively; accuracy was 81.4%. CONCLUSIONS: The case definition, for a cutoff of at least 7 criteria, reached average sensitivity and specificity, but with a high positive predictive value. Its simplicity and low cost make it useful for rapid bedside leptospirosis diagnosis in Brazilian hospitalized patients with acute severe febrile disease

Pneumonia lipóide exógena: importância da história clínica no diagnóstico Exogenous lipoid pneumonia: importance of clinical history to the diagnosis

A pneumonia lipóide é uma doença rara, resultante da microaspiração de formulações lipídicas. Para seu diagnóstico, o grau de suspeição clínica deve ser elevado. Relata-se o caso de uma mulher com passado de câncer de mama, apresentando dispnéia e tosse progressivas e infiltrado pulmonar bilateral na radiografia. A suspeita de linfangite carcinomatosa com indicação de quimioterapia foi questionada por achados não usuais na tomografia computadorizada de alta resolução e história de ingestão crônica de laxantes contendo óleo mineral. A biópsia pulmonar confirmou pneumonia lipóide, que deve ser considerada em pacientes com pneumopatia difusa e exposição a potenciais agentes causadores.<br>Lipoid pneumonia is a rare disease resulting from the micro-aspiration of lipid formulations. Making a diagnosis of lipoid pneumonia requires a high degree of clinical suspicion. Herein, we report the case of a female patient with a history of breast cancer, presenting progressive dyspnea and cough, together with radiological findings of bilateral pulmonary infiltrate. The working diagnosis of lymphangitic carcinomatosis, for which chemotherapy would be indicated, was called into question based on the high-resolution computed tomography findings and on the fact that the patient had a history of chronic ingestion of laxatives containing mineral oil. A lung biopsy confirmed a diagnosis of lipoid pneumonia, which should always be considered in patients with diffuse lung disease having been exposed to potential causative agents
