Researchers from Tulane University in New Orleans, LA, evaluated 40 patients aged 5 to 12 years with chronic cough (> 8 weeks in duration) with no obvious cause. Each patient underwent extensive multispecialty testing.

Results showed that reflux was the single most commonly associated factor of chronic cough by itself (27.5 percent), followed by allergy (22.5 percent). All patients received treatment for their underlying conditions, and all responded to their respective treatments.

This study is published in the September issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians.
