Randomized Controlled Trial
Endotracheal tube cuff pressure alteration after changes in position in patients under mechanical ventilation.
The purpose of this study was to investigate endotracheal tube cuff pressure (Pcuff) alteration in patients under mechanical ventilation after changes in position. ⋯ Changes in body position can cause significant Pcuff variations in patients under mechanical ventilation.

Comparative Study
Comparison among pulmonary function test results, the Shwachman-Kulczycki score and the Brasfield score in patients with cystic fibrosis.
To study correlations among pulmonary function, chest radiology and clinical status in cystic fibrosis. ⋯ These two scoring systems are complementary, correlating with each other, as well as with pulmonary function tests. The radiology domain of the S-K scoring system is a good alternative to the Brasfield score.

Case Reports
Pulmonary complications of crack cocaine use: high-resolution computed tomography of the chest.
Here, we report high-resolution computed tomography (HRCT) findings in a patient who developed sudden hemoptysis, dyspnea and chest pain after smoking crack cocaine. Chest X-rays showed consolidations, primarily in the upper lobes, and HRCT scans showed ground glass attenuation opacities, consolidations and air-space nodules. A follow-up CT, after drug use discontinuation and administration of corticosteroids, showed partial resolution of pulmonary lesions and the appearance of cavitations. Clinical, imaging and laboratory findings led to a diagnosis of 'crack lung'.
