Conference paper (other academic/artistic)abstract
- Background: In the Department of Occupational and Environmental Dermatology there has been an increase in the inflow of patients, working as surgical nurses or surgeons. They have been referred due to presumed occupational contact dermatitis. Results from investigated patients have in part been presented previously, where the investigation has shownmultiple contact allergies caused by their occupational use of gloves. Allergens such as diphenylguanidine were found in the gloves and contact allergies to their rubber gloves were found. Many of the patients have been working for decades in their present occupation, but the hand dermatitis had often been present for less than a year. Objectives: To present a follow-up of patientswith hand dermatitis due to gloves. Methods: A follow-up of the patients and a structure for the investigation of the individual patient are given. Results: The cases will be presented with their contact allergies, howtheinvestigation isperformedandtheoutcomeof theprevention by avoiding gloves containing the allergens diagnosed in the individual patients. Conclusions: For health care personnel hand hygiene and the wearing of protective gloves are mandatory. Our findings indicate that the increased need to use rubber gloves and at the same time the exclusion of latex gloves give rise to new contact allergies which are clinically relevant. In the investigation, and the advice given to the patients, several factors have to be taken into consideration, including the fast change of glove material. The cases indicate the importance of close cooperation between chemists and dermatologists and the possibility to perform chemical analysis. Furthermore, and just as important for this patient group, is that with correct diagnosis and advice the contact dermatitis can actually heal completely and the patients continue in their work.

Contact allergy investigations in healthcare workers with face mask-related skin disease
- 2023
-
In: Contact Dermatitis. - 0105-1873. ; 89:1, s. 16-19
-
Journal article (peer-reviewed)abstract
- Background: During the COVID-19 pandemic, the use of face masks has increased among healthcare workers (HCWs). Questionnaire studies have shown a high frequency of self-reported facial adverse skin reactions. Case reports have been published on face mask-induced allergic contact dermatitis and urticaria. Objectives: To describe the results of the contact allergy investigations in consecutive HCWs investigated for skin reactions to face masks during the COVID-19 pandemic and the results of the chemical investigations of face masks supplied by the hospital. Methods: Participants were patch tested with baseline series and chemicals previously reported in face masks not included in the baseline series. Face mask(s) brought by the HCW were tested as is and/or in acetone extract. Chemical analyses were performed on nine different face masks for potential allergens. Results: Fifty-eight HCWs were investigated. No contact allergies were found to the face mask(s) tested. Eczema was the most common type of skin reaction, followed by an acneiform reaction. Colophonium-related substances were found in one respirator and 2,6-di-t-butyl-4-methylphenol (BHT) were found in two respirators. Conclusion: Based on this report, contact allergies to face masks is uncommon. Patch test with colophonium-related substances and BHT should be considered when investigating adverse skin reactions to face masks.

Hand eczema and occupational contact allergies in healthcare workers with a focus on rubber additives
- 2018
-
In: Contact Dermatitis. - : Wiley. - 0105-1873. ; 79:3, s. 149-156
-
Journal article (peer-reviewed)abstract
- Background: Hand eczema (HE) in healthcare workers (HCWs) is common. Besides wet work, healthcare work also implies exposure to contact allergens. Objectives: To assess HE and contact allergy related to occupational exposures in HCWs. Methods: In a cross-sectional study, 311 HCWs with HE within the preceding 12 months and a control group of 114 HCWs without HE were investigated with the baseline series and a special patch test series based on substances found in the gloves, soaps, alcoholic hand disinfectants and hand creams provided at the hospitals. Results: Contact allergy to rubber additives was significantly more common in HCWs with HE (6%) than in HCWs without HE (1%, P =.02). The corresponding percentages for fragrances were 11% and 3%, respectively (P =.004). Occupational HE was found in 193 of 311 (62%) HCWs. Of these, 22 of 193 (11%) had occupational allergic contact dermatitis, including 17 with glove-related rubber contact allergy. Contact allergy to diphenylguanidine was as common as contact allergy to thiurams. Occupational contact allergy to rubber additives was significantly associated with sick-leave related to HE. Conclusion: Contact allergy to rubber additives in medical gloves is the most common cause of occupational allergic contact dermatitis in HCWs. Aimed patch testing with relevant rubber additives is mandatory when HE in HCWs is investigated.
