This document discusses occupational disorders such as occupational asthma. Some key points are: occupational asthma accounts for about 15% of new asthma cases in adults and results in over 1 million disability cases annually. Diagnosis involves a work history and objective tests like spirometry. Treatment involves avoiding the causal agent, though symptoms may persist, as well as medications like inhaled corticosteroids. The prognosis is generally poor, with only 1/3 achieving long-term recovery even after avoiding exposure.
