title: A teenager with an annoying cough.
abstract: Chronic cough is a stressful condition and can lead to extensive investigations. Bronchial asthma and postnasal drip syndrome are common causes, but sometimes the origin of cough is outside the respiratory tract (1,2). Such a relatively simple test as esophageal pH probing may suggest appropriate (antireflux) therapy.
