RESUMEN

BACKGROUND: Hand eczema is a common inflammatory skin disorder. Health care providers need continuously updated information about the management of hand eczema to ensure best treatment for their patients. OBJECTIVES: To update the European Society of Contact Dermatitis guideline on the diagnosis, prevention, and treatment on of hand eczema. METHOD: The Guideline Development Group (GDG) was established on behalf of the ESCD. A call for interest was launched via the ESCD website and via the ESCD members' mailing list. Appraisal of the evidence for therapeutic and preventive interventions was applied and a structured method of developing consensus was used and moderated by an external methodologist. The final guideline was approved by the ESCD executive committee and was in external review on the ESCD webpage for 1 month. RESULTS: Consensus was achieved for several statements and management strategies. CONCLUSION: The updated guideline should improve management of hand eczema.

RESUMEN

Objectives This study aimed to assess whether the occurrence of skin problems in 2006 (baseline) was associated with response frequency, quitting a job due to health problems, and change in occupational skin exposures in 2009. Methods We conducted a three-year prospective study of the general working population of Norway. Associations between baseline indicators (sex, age, education, occupation), and occurrence of skin problems with response frequency at follow-up were assessed with Chi-square test and unconditional logistic regression. Associations between the occurrence of skin problems at baseline with quitting a job due to health problems and skin exposure at follow-up were also assessed with unconditional logistic regression. Results We found no evidence of an association between the occurrence of skin problems at baseline and a lower response frequency at follow-up. Age, sex, education, and occupation were the most important predictors for response at follow-up. Skin problems at baseline consistently predicted quitting a job due to health problems at follow-up. No evidence of change in the patterns of occupational skin exposures at follow up in 2009 was found for workers reporting skin problems in 2006. Conclusion While skin problems at baseline were not related to a lower response frequency at follow-up, our results suggest that workers reporting skin problems may quit their jobs due to health problems. Preventive efforts are still needed to reduce hazardous occupational skin exposures among workers reporting skin problems.

RESUMEN

BACKGROUND: In 2011, a multicentre study was conducted in order to determine how hair dye manufacturers instructed consumers to perform a self-test prior to dyeing their hair, in order to identify individuals who are likely to react upon subsequent hair dyeing. A number of concerns were raised concerning the variability in instructions between products and producers, and the safety and validity of this tool. OBJECTIVES: To perform a 5-year follow-up study in order to determine whether manufacturers still recommend a self-test, and if so, whether the procedures have been changed. METHODS: During March 2016, a total of 40 oxidative hair dye products from 21 different manufacturers were bought in retail stores in 8 European countries. RESULTS: The consumers were instructed to perform a self-test prior to hair dyeing for 39 of the products; however, the procedures varied greatly regarding the method of application, the amount of hair dye applied, the location and size of the application area, the number of applications, whether or not rinsing was performed after application, the reading times, and how a positive reaction was defined. CONCLUSIONS: Self-testing is still recommended by almost all manufacturers of permanent hair dyes. There are major variations in the instructions, even in products from the same manufacturer. The previously raised concerns regarding safety and validity still remain.

RESUMEN

Little is known about the contribution of occupational skin exposure as a risk factor for physician-certified long-term sick leave in the general working population of Norway. This study drew a cohort (n = 12,255; response at baseline 69.9%) randomly from the general population of Norway. Occupational skin exposure (in 2009) was measured based on 5 items. The outcome of interest was physician-certified long-term sick leave ≥ 16 days during 2010. Statistical adjustment for psychosocial and mechanical occupational exposures was performed. Long-term sick leave was predicted by occupational skin exposure to cleaning products (odds ratio (OR) 1.7; 95% confidence interval (95% CI) 1.1-2.5) and waste (OR 2.1; 95% CI 1.1-3.7) among men, and occupational skin exposure to water (OR 1.3; 95% CI 1.0-1.6) among women. The estimated population attributable risk for occupational skin exposure was 14.5%, which emphasizes its contribution as an important risk factor for long-term sick leave.
