Occupational airway diseases

In this review we describe characteristics of occupational airway diseases, as well as physical and chemical characteristics of agents inducing airway disease. Occupational airway diseases include industrial bronchitis, reactive airway dysfunction syndrome, bronchiolitis obliterans, and occupational asthma. High- and low-molecular weight substances associated with occupational airway disease are listed. The importance of host factors is stressed. Diagnostic approaches, particularly indicators for specific challenge testing with occupational materials, are described. Preventive and control measures are presented.
