Investigation of an Outbreak of Photodermatitis Confined to One Shop in a Large Factory

RESUMO

Out of 106 men employed in a foundry attached to a large factory, 29 men developed a photosensitization dermatitis over the period of three months. Three men out of 1,700 employed in the remainder of the works developed a similar eruption, but no common factor was apparent. Owing to the very high incidence in the foundry, a sensitizer associated with the process was suspected and it seemed likely that it would prove to be an atmospheric contaminant. Many chemical investigations and skin tests were carried out without positive result, though much interesting information regarding combustion products of various materials was obtained.
