Occupational contact dermatitis in North American print machine operators referred for patch testing: retrospective analysis of cross-sectional data From the North American Contact Dermatitis Group 1998 to 2014 Journal Article uri icon
  • BACKGROUND: Little is known about the epidemiology of contact dermatitis (CD) in print machine operators (PMOs). OBJECTIVE: The aims of this study were to estimate the prevalence of CD and characterize clinically relevant and occupationally related allergens among PMOs undergoing patch testing. METHODS: This was a retrospective cross-sectional analysis of the North American Contact Dermatitis Group data from 1998 to 2014. RESULTS: Of 39,332 patch-tested patients, 132 (0.3%) were PMOs. Among PMOs, most were male (75.0%) and white (92.4%). The majority were printing press operators (85.6%). The most frequent sites of dermatitis were hands (63.6%), arms (29.5%), and face/scalp (24.2%). More than half had an occupationally related skin condition (56.1%). Final diagnoses were most commonly allergic CD (58.3%) and irritant CD (33.3%). Cobalt (20.8%), carba mix (12.5%), thiuram mix (8.3%), and formaldehyde (8.3%) were the most frequent occupationally related allergens. The top allergen sources included inks (22.9%), gloves (20.8%), and coatings/dye/copy/photographic chemicals (14.6%). CONCLUSIONS: Allergic CD, irritant CD, and involvement of exposed body areas were common among PMOs. Common allergens included rubber accelerators, metals, and preservatives.
