SYNOPSISReactive airways dysfunction syndrome (RADS), shares many of the clinical characteristics of asthma and may result in an intractable cough, wheezing, and recurrent dyspnea, even after a single exposure to a toxic inhalant. This well performed clinical-pathologic study suggests that, although RADS is often treated like asthma, its response to standard bronchodilator regimens is likely to he limited as a result of airway fibrosis.SOURCEGautrin D, et al.
