Recurrent nocturnal asthma due to tolylene di-isocyanate: a case report.
In a carpenter with a history of nocturnal dyspnoea, a bronchial provocation test with a tolylene di-isocyanate (TDI) activator elicited a non-immediate asthmatic reaction, followed by recurrent nocturnal asthma for five subsequent nights. Subsequently, the study of the circadian rhythm of airflow, registered during work, confirmed the presence of recurrent nocturnal asthma of occupational origin.
