World Trade Center cough syndrome and its treatment

To date, the main respiratory health consequence from the collapse of the World Trade Center (WTC) on September 11, 2001 has been the "WTC Cough Syndrome" (chronic rhinosinusitis, asthma, and/or bronchitis, often complicated by gastroesophageal reflux dysfunction). Syndrome incidence and severity have been linked to WTC dust exposure intensity. While it is too early to ascertain long-term effects of WTC dust exposure, effective treatment guidelines have been designed through a collaborative effort by the three established centers of excellence for WTC medical monitoring and treatment and the WTC Registry. These treatment recommendations are described here.
