Endoscopic sealing of bronchopleural fistulas with submucosal injection of a tissue expander: a novel technique.

The occurrence of a bronchopleural fistula (BPF) continues to represent a challenging management problem, and is associated with high morbidity and mortality. A novel and successful technique that uses submucosal injection of a tissue expander for bronchoscopic occlusion of BPFs has been designed. This method may be used either alone or in combination with bronchoscopic instillation of n-butyl-cyanoacrylate glue.

CPAP titration: Different methods for similar clinical results.

Background: Continuous positive airway pressure (CPAP) is the main treatment for obstructive sleep apnea-hypopnea syndrome (OSAHS). Polysomnography (PSG) is the gold standard for CPAP titration. However, alternative methods have been sought to titrate CPAP at less expense in terms of time and resources.
