Early/late response model: implications for control of asthma and chronic cough in children

Treatment options in the child with a chronic cough

Chronic cough is a common symptom in many different disease processes. Because the most effective way to eliminate a chronic cough is to identify and treat the underlying disease, the physician must approach the paediatric patient based on his or her knowledge of the differential diagnosis. The most common causes of cough in children are upper respiratory tract infections, asthma, rhinitis, sinusitis, and gastroesophageal reflux. By using a systematic approach, the cause of a chronic cough can almost always be found, and the cough successfully treated. Asthma is the cause of most undiagnosed chronic coughs but sinusitis, rhinitis, and gastroesophageal reflux must also be considered in difficult patients.
