Reporting of ethical committee (EC) approval and patient consent in publications involving human subjects may be lower than recommended. In this paper this ethical issue was analysed in the Portuguese Journal of Pulmonology and in the other two Portuguese medical journals with impact factor indexed in the ISI Web of Knowledge. ⋯ Reporting of EC approval and patient consent in the three leading Portuguese medical journals has been lower than in their leading world counterparts. This should be taken into account and further audited in future, not only for the protection of the research subjects but also to maintain public trust in the process.

Randomized Controlled Trial Multicenter Study
Sedation with midazolam in flexible bronchoscopy: a prospective study.
Sedatives have been increasingly used to improve patient comfort during flexible bronchoscopy (FOB). Due to its rapid-onset, anxiolytic and amnestic properties, midazolam is one of the most commonly used sedatives. ⋯ Sedation with midazolam in FOB improved patient's comfort and decreased complaints, without significant haemodynamic changes. It should be offered to the patient on a routine basis.

Comparative Study
Pulmonary function tests in obese people candidate to bariatric surgery.
Obesity is considered one of the most serious public health problems of the modern world. Because it alters the relationship between the lungs, chest wall and diaphragm, it is to be expected that it impacts on the respiratory function. In Portugal, there is not much data about the relationship between obesity and pulmonary function. ⋯ Nevertheless, in 13 patients the FRC remained decreased. After weight loss, the only correlation found was between reduction of BMI and increased FRC (r = -0.371; p = 0.028). This study suggests a relationship between obesity and pulmonary restriction and a positive impact of bariatric surgery in PFT.

The objective of this study was to review chest radiographs (CXR) and chest computer tomography (CT) findings in patients with influenza A H1N1 virus pneumonia. ⋯ Bilateral ground-glass opacities and areas of consolidation were the predominant radiological findings of influenza A (H1N1) virus pneumonia. Multifocal bilateral opacities and CXR score are strictly correlated with the severity of the illness.
