摘要
A 63-year-old nonsmoking white man presented to the clinic with a 2-year history of cough. The cough was dry, and it was worse at night. The cough had begun after an upper respiratory tract infection and a trip to South America. The patient was prescribed antibiotics by a family physician but had no improvement; he was then given a combination inhaler (salmeterol and fluticasone) and had minimal improvement.
