RESUMO

Gandevia, B., and Milne, J. (1970).Brit. J. industr. Med.,27, 235-244. Occupational asthma and rhinitis due to Western red cedar (Thuja plicata), with special reference to bronchial reactivity. With the increasing use of Western, or Canadian, red cedar (Thuja plicata) in the timber industry, a distinctive respiratory syndrome of rhinitis and asthma has been observed with increasing frequency in clinical and industrial practice. Six cases of asthma and four of rhinitis are described in some detail; the onset of symptoms some hours after exposure, the nocturnal predominance of symptoms, especially of cough, and their persistence for days or weeks after cessation of exposure may conspire to make diagnosis difficult if the occupational hazard is not appreciated.
