Background: The validity of the self-report questionnaire for hand eczema (HE) among Croatian hairdressers was not investigated previously, leading to uncertainty in the prevalence estimated from self-reported data., Objectives: To (1) investigate the validity of the self-report questionnaire for HE in hairdressing apprentices and (2) examine the differences between apprentices who recognised their HE symptoms and those who did not., Methods: Clinical examination for HE signs on hands and wrists was performed by the Osnabrueck Hand Eczema Severity Index for 408 apprentices at four visits covering the entire schooling period. Self-report HE was based on the Nordic Occupational Skin Questionnaire., Results: Low sensitivity (7%-37%) with high specificity (≥95%) was observed, with both measures improving from baseline to last visit. The severity of HE signs was the only factor associated with the correct identification of HE signs in analyses adjusted for previous HE signs, health-related quality of life, and atopic dermatitis (adjusted odds ratios of 1.58 with 95% confidence interval [1.06-2.35] and 1.74[1.38-2.19] at second and third follow-up visit, respectively)., Conclusions: Self-report questionnaire for HE showed low sensitivity in hairdressing apprentices, especially at the beginning of training and in those with mild symptoms. Further validation studies following questionnaire modifications aimed at adolescent population are advised., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: It is known that a large number of hairdressing apprentices (HA) develop occupational contact dermatitis (OCD) during schooling, but studies that address prevalence of contact sensitization in HAs with hand eczema are missing., Objectives: To assess the prevalence, incidence rate and clinical characteristics of OCD, including contact sensitization, in a sample of Croatian HAs., Materials and Methods: A total of 408 HAs from 25 Croatian towns were examined at the beginning of education and monitored at the end of each school year. Clinical evaluation of skin changes was performed using the Osnabrueck Hand Eczema Severity Index (OHSI). Standard patch test (PT) with baseline and hairdresser series of contact allergens was performed in 46 HAs with skin changes lasting ≥3 months., Results: The overall incidence rate of OCD was 32.3/100 person-years, and the 3-year prevalence 50.3%. Contact sensitization was found in 14 out of 46 (30.3%) HAs, with 10 of these 14 HAs (71.4%) sensitized to specific hairdressing allergens. The strongest reactions were found to PPD. HAs with positive PT had higher OHSI than HAs with negative patch test (median, IQR: 3, 2-4 vs. 2, 2-4)., Conclusions: Contact sensitization to specific hairdressing chemicals was found in 71.4% of HAs with a positive patch test, supporting evidence on the early contact sensitization to occupational allergens among HAs., (© 2023 John Wiley & Sons A/S.

Background: Chronic hand eczema (CHE) is a very common skin disease among the European population. It causes itch and pain and, in more severe cases, seriously impairs hand functioning at work and in private life., Objectives: To explore perspectives of people with lived experience on CHE-related problems, wishes and goals., Methods: Following a qualitative approach, we conducted topic-guided interviews in five European countries and applied template analysis to identify recurrent themes among patients with CHE., Results: We interviewed 60 patients in seven outpatient dermatological and occupational medicine clinics in Croatia, Denmark, Germany, the Netherlands and Spain. Five main themes were identified: (1) knowledge about the disease and its course, (2) preventive behaviour, (3) hand eczema therapy, (4) impact on everyday life and (5) attitudes towards CHE and healthcare. Participants did not feel well informed about CHE, especially about causes, triggers and treatment options. Preventive measures were experienced as more or less effective but also cumbersome. Experiences with therapy were diverse. Treatment satisfaction depended on the results and on the perceived support from the treatment teams. Participants found it important to be taken seriously, to receive practical advice, to try out additional treatments or examinations, find new hope and have occupational perspectives. They wished that others could better understand the physical and emotional burden of CHE. Patient support groups were not mentioned. Participants found it important to learn to take care of themselves and accept life with CHE., Conclusions: Due to its annoying symptoms, high visibility and impaired functioning at work and in private life, CHE has a high emotional and social impact. Some people may require support to learn coping with CHE and its prevention. Patients wish for information about causes and triggers. They value physicians who listen to them and keep looking for solutions., (© 2023 The Authors.

Background: Hand eczema (HE) is a common skin disease characterized by itch, pain and visible skin changes such as fissures, erythema and vesicles. It is not yet clear which outcome domains are most important for patients. The Hand Eczema Core Outcome Set (HECOS) initiative is developing a consented set of core domains and suitable measurement instruments for the future application in all HE trials. This includes an online Delphi survey about core domains, which requires a 'Long List' of all domains that might be important to measure., Objectives: To compile a 'Long List' of candidate outcome domains for therapeutic HE trials with suggestions from patients and experts., Methods: First, 60 patients with chronic HE were interviewed at seven study sites in Croatia, Denmark, Germany, the Netherlands and Spain. Patients were asked about domains that were important from their perspectives. Second, 185 HE experts were invited by email to complete an online survey. With an open question, they were asked to suggest up to six domains., Results: Suggestions were provided by 58 patients and 82 experts. Most patients and experts suggested to measure the domains 'signs', 'symptoms' and 'HE-related quality of life'. Specifically, >25% of patients said that less itch, pain or fissures indicated a successful treatment. Among experts, >25% suggested 'itch' and 'ability to work' as core sub-domains. Further outcomes from the domains 'HE control over time', 'patient-reported treatment experience' and 'skin barrier function' were mentioned., Conclusion: 'Itch' was rated high among patients with HE and professional HE experts. While patients emphasized fissures as important, experts underlined the ability to work. This investigation allowed us to define a 'Long List' of 7 candidate outcome domains with 58 sub-domains. From this list, a panel of stakeholders will select core domains during an online Delphi survey., (© 2023 The Authors.

Background: Hairdressers are commonly affected by hand eczema (HE) due to skin hazardous exposure such as irritants and allergens in the work environment., Objective: To give an overview of the current prevalence, incidence, and severity, as well as the pattern of debut and the contribution of atopic dermatitis on HE in hairdressers., Methods: A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines was performed. Studies published from 2000 to April 2021 that fulfilled predefined eligibility criteria were retrieved., Results: A pooled lifetime prevalence of 38.2% (95% confidence interval [CI] 32.6-43.8), a pooled 1-year prevalence of 20.3% (95% CI 18.0-22.6), and a pooled point prevalence of 7.7% (95% CI 5.8-9.6) of HE was observed in hairdressers. The lifetime prevalence in fully trained hairdressers and hairdressing apprentices was almost identical. The pooled incidence rate of HE was 51.8 cases/1000 person-years (95% CI 42.6-61.0) and the pooled prevalence of atopic dermatitis was 18.1% (95% CI 13.6-22.5)., Conclusion: HE is common in hairdressers and most hairdressers have debut during apprenticeship. The prevalence of atopic dermatitis in hairdressers is comparable with estimates in the general population, indicating that occupational exposures are the main factor in the increased prevalence of HE in hairdressers. This warrants a strategic and collective effort to prevent HE in hairdressers., (© 2022 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Apprentice nurses are considered at high risk to developing occupational skin diseases., Objectives: This study assessed the frequency and origin of hand eczema, and work-related risk factors in apprentice nurses., Methods: The study involved 240 final-year apprentice nurses (females 75%, median age 19 years) from vocational schools in Zagreb, Croatia. The study was performed in 2020/2021 and included a questionnaire and clinical examination by means of the Osnabrück Hand Eczema Severity Index (OHSI). Skin prick test (SPT) with natural rubber latex (NRL) allergen, and patch test with the basic series of allergens, and disinfectants, were performed in 42 apprentice nurses with hand eczema that lasted more than 3 months., Results: Clinically observed and self-reported hand eczema were found in 49% and 46% of apprentice nurses, respectively. Those with observed changes were older and reported more days per month spent on practical work than those with healthy skin (P = .001). Median OHSI was 4 (interquartile range 2-6). There were no positive SPTs to latex, and 11 (26%) apprentice nurses had positive patch test reactions to one or more tested allergens, mostly nickel., Conclusions: Hand eczema was common in final-year apprentice nurses during the COVID-19 pandemic. It was mostly of irritative origin, associated with the duration of practical training, confirming cumulative effect of hazards on skin barrier., (© 2021 John Wiley & Sons A/S.

Background/aims: The aim of this study was to obtain insight into the clinical course and prognosis of allergic contact dermatitis (ACD), including potential effects of genetic and environmental factors., Methods: Eighty-two patients with previously defined ACD acquired occupationally (OACD) or non-occupationally (NOACD) were patch retested and evaluated for the presence of persistent eczema, atopy and filaggrin mutations., Results: The crude risk for the persistence of a positive patch test (PT) reaction was 6.3 times higher (95% CI 3.63-11.0) for PT reactions assessed as '+++' compared to '++' reactions at the first PT. Among the categories of OACD, NOACD, age, gender, atopy, and the number of positive PT reactions at the first and second PT, only OACD (OR 10.0, 95% CI 1.95-51.2) and number of positive PT reactions at retesting (OR 3.85, 95% CI 1.57-9.44) were found to be predictors of persistent eczema., Conclusions: Occupationally acquired contact allergy was emphasized as the most important factor in predicting poor prognosis of ACD.

Healthcare workers (HCWs) can be considered at an increased risk of developing occupational contact dermatitis (OCD) due to repetitive hand washing with soaps and disinfectants and extended use of gloves for many hours during the day. The aim of this study was to summarize the incidence of OCD in HCWs. We searched the databases PubMed/MEDLINE (1980‐present), EMBASE (1980‐present) and Cochrane Library (1992‐present) through May 2020 using the search term 'incidence of contact dermatitis in HCWs' according to Preferred Reporting Items for Systematic Reviews and Meta‐analyses (PRISMA) guidelines. Overall, 16 studies (six cohorts; 10 register‐based) with follow‐up periods between 1987 and 2013 fulfilled the inclusion criteria. The incidence of OCD reported in studies using registers of occupational diseases ranged from 0.6 to 6.7 per 10 000 person‐years. The cohort studies reported incidence from 15.9 to 780.0 per 10 000 person‐years; the incidence was higher in studies which included apprentice nurses. A higher incidence was also observed amongst dental practitioners, particularly dental technicians and nurses, compared to other HCWs. Studies reporting incidence data are very scarce and results differed by study design, type of contact dermatitis and investigated HCWs. Our study highlighted the dearth of high‐quality data on the incidence of OCD and the possible underestimation of disease burden. Prospective cohort studies with harmonized designs, especially exposure assessment and outcome ascertainment, are required to provide more accurate, valid and recent estimates of the incidence of OCD. A high incidence amongst specific occupational groups suggests the need to undertake intervention studies with a focus on prevention, particularly during pandemics such as COVID‐19.
