Title Most frequent allergens in the metalworking industry
Original title Alergenos más frecuentes en los trabajadores de la industria metalúrgica [in Spanish]
Bibliographic information Dec. 2003, Vol.L, No.193, p.7-14. Illus. 12 ref.
Abstract The aim of this study was to identify the allergens that most frequently cause allergic contact eczema in the metalworking industry. It involved 251 workers who had consulted an occupational dermatology service between 1999 and 2002 for cases of suspected contact dermatitis. Standard battery skin tests were carried out. 106 workers (42%) showed a positive reaction to at least one substance. The most frequent positive reactions were observed for chromium, nickel, thimerosal mix, cobalt, thiuram mix and formaldehyde. Among the 69 patients who were also subjected to patch tests with various cutting fluids, 20 (29%) showed a sensitization reaction, mainly for thimerosal mix, formaldehyde and certain biocides. Injuries affected primarily the fingers, hands and arms.
