Pleuroscopy provides the pulmonologist with a unique opportunity to visualize the contents of the pleural space, perform biopsy of the parietal pleura under direct visual guidance, allow optimal chest tube placement and perform pleurodesis to prevent recurrent pleural effusion or pneumothorax in selected patients. We discuss the techniques, indications, contraindications and complications of pleuroscopy using rigid and semirigid instruments. In addition, the potential value and expanding role of pleuroscopy with semirigid instrumentation is debated.

Mucociliary clearance in patients with chronic asthma: effects of beta agonists.
Chronic asthma is characterized by airway inflammation, mucus hypersecretion and impaired mucociliary clearance (MCC). We investigated baseline MCC and the acute effect of terbutaline in chronic asthmatics with sputum production while on long-term treatment with salmeterol in combination with inhaled corticosteroids (ICS). ⋯ MCC was impaired in most of these asthmatics with persistent airway obstruction and sputum production, despite regular treatment with ICS and salmeterol. In addition, there was little or no stimulation of MCC acutely after terbutaline in most of these asthmatics.
