Wheat Miller's Asthma in Sri Lanka
Central Chest Clinic, Colombo, Sri Lanka
Occupational asthma in wheat millers is well documented but it has not previously been reported from a non-wheatgrowing country. Sixteen wheat millers with disabling asthma from Sri Lanka where they handled imported and therefore old wheat were studied. They developed asthma after working for an average of 5.2 years in the industry. Eleven of them were followed up after retirement: 9 had complete remissions while the other 2 had partial remissions at the time of examination which were at 1 and 1
months respectively after retirement. In one worker the remission was immediate, while the others took up to 3 months. The time taken for the remission to occur appears to depend on the intensity of asthma during weekends rather than its severity during working days. Length of service, duration of asthma and smoking did not influence these remissions.
