A preliminary quality of life questionnaire-bronchiectasis: a patient-reported outcome measure for bronchiectasis.

Background: The Quality of Life Questionnaire-Bronchiectasis (QOL-B) is the first disease-specific, patient-reported outcome measure for patients with bronchiectasis. Content validity, cognitive testing, responsivity to open-label treatment, and psychometric analyses are presented.

Methods: Reviews of literature, existing measures, and physician input were used to generate the initial QOL-B.

Pharmacologic agents for mucus clearance in bronchiectasis.

There are no approved pharmacologic agents to enhance mucus clearance in non-cystic fibrosis (CF) bronchiectasis. Evidence supports the use of hyperosmolar agents in CF, and studies with inhaled mannitol and hypertonic saline are ongoing in bronchiectasis. N-acetylcysteine may act more as an antioxidant than a mucolytic in other lung diseases.

Pulmonary artery sarcoma: a case report of surgical cure and 5-year follow-up.

Pulmonary artery sarcoma is a rare tumor that is frequently misdiagnosed as chronic pulmonary embolism. With heightened clinical awareness and advancement in technology, the diagnosis is now increasingly being made preoperatively. Previous literature has described the disease to be uniformly fatal, with surgical resection as the single most effective modality for short-term palliation.
