Respiration; international review of thoracic diseases

The use of endoscopically placed unidirectional valves for the treatment of emphysema is increasing. With better patient selection, there is also an increased likelihood of complications associated with the procedure, such as postprocedural pneumothorax. ⋯ This report describes an expert recommendation that has been developed to outline pneumothorax management after valve placement to inform physicians and patients of the risk-benefit profile and to assist them in decision making. Skilled and aggressive pneumothorax management is necessary in this patient population, and by following these recommendations traumatic scenarios, prolonged drainage, extended hospitalizations, and/or surgery might be avoided in many cases.

Cystic fibrosis (CF) lung disease starts in the first months of life often before the onset of clinical symptoms. Multiple breath washout (MBW) detects abnormal lung function in infants and young children in the laboratory setting. ⋯ We conclude that MBW is feasible and sensitive to detect abnormal lung function in infants and young children with CF in the clinical setting.

Review Meta Analysis
Diagnostic yield and safety of electromagnetic navigation bronchoscopy for lung nodules: a systematic review and meta-analysis.
Electromagnetic navigation bronchoscopy (ENB) is an emerging endoscopic technique for the diagnosis of peripheral lung lesions. A thorough analysis of ENB's yield and safety is required for comparison to other sampling modalities. ⋯ ENB is effective and particularly safe. Prospective studies are needed to clarify the role of several variables conditioning the yield of this technique.

Randomized Controlled Trial
Effects of bronchodilators on regional lung sound distribution in patients with chronic obstructive pulmonary disease.
Bronchodilators have been reported to influence regional lung ventilation in patients with chronic obstructive pulmonary disease (COPD), which may change regional lung sound distribution. Vibration response imaging (VRI) is a lung imaging system for the assessment of breath sounds. ⋯ The additional use of an SABA by COPD patients improved their pulmonary function, which was accompanied by changes in regional lung air flow. The distribution of emphysematous lesions and the bronchial reactivity to SABA appeared to affect the redistribution of the lung sounds following bronchodilator administration.
