Although asthma is the most common type of occupational lung disease seen in primary care, physicians need to be aware of other presentations of work-related respiratory illness. In part 2 of this two-part article, the authors present a primary care-oriented review of occupational diffuse parenchymal lung disease and irritant reactions. They discuss when and to whom to refer patients with complicated conditions as well as provide specific sources for additional information on occupational lung diseases and toxicant exposures.
