RESUMEN
BACKGROUND: Mainly women work as foot care specialists (FCS). They are at risk to develop occupational dermatitis (OD). OBJECTIVES: The objective of this study is to describe the contact sensitisation pattern of female FCS with OD. METHODS: In a retrospective study, patch test and clinical data collected by the Network of Departments of Dermatology (IVDK) from 2008 to 2022 were analysed. Data of 116 female FCS with OD were compared with data of 13 930 female patients with OD working in other professions and 78 612 female patients without OD. RESULTS: Hand dermatitis (93.1%) was significantly more common and face dermatitis (0.9%) significantly less common in female FCS with OD compared to other female patients with or without OD. Frequent suspected allergen sources were disinfectants, gloves, leave-on and nail cosmetics. Occlusion and wetness were important co-factors. The most common diagnoses were irritant contact dermatitis (26.7%) and allergic contact dermatitis (21.6%). No sensitisation to any of the baseline series allergens was significantly more frequent in female FCS with OD than in the two control groups. However, sensitisations to allergens which FCS are abundantly exposed to, including fragrances, preservatives, rubber ingredients and disinfectants, were most common. CONCLUSIONS: FCS should be aware of the OD risk and prevention should be promoted.

BACKGROUND: Most studies investigating the prevalence of hand eczema (HE) in professional cleaners use self-reported questionnaire-based data. However, no validation studies of self-reporting of HE among professional cleaners have previously been conducted. OBJECTIVES: To investigate (1) the point prevalence of self-reported HE, (2) the point prevalence of HE estimated by physical examination of the hands and (3) the sensitivity and specificity of self-reporting of HE compared with the diagnosis based on physical examination among professional cleaners. METHODS: Professional cleaners at three different hospitals in Region Zealand were invited to fill out a questionnaire. The point prevalence of self-reported HE was estimated based on questions from the Nordic Occupational Skin Questionnaire. After completing the questionnaire, each cleaner underwent a physical examination of the hands by a dermatologist on the same day. RESULTS: In total, 234 cleaners were invited to participate in the study, and 224 (response rate = 96.0%) agreed to take part. Based on the self-reported questionnaires, 5.3% (n = 12) of the cleaners had current HE. Based on an examination by a physician, 19.2% (n = 43) of the cleaners had current HE. The sensitivity of self-reported HE was found to be 28.0%, while the specificity was found to be 100.0%. The positive predictive value was found to be 100.0%, while the negative predictive value was 85.0%. CONCLUSION: The true point prevalence of HE among professional cleaners is underestimated when based on self-reporting.

Occupational dermatoses impose a significant socioeconomic burden. Allergic contact dermatitis related to occupation is prevalent among healthcare workers, cleaning service personnel, individuals in the beauty industry and industrial workers. Among risk factors, the exposure to preservatives is frequent, since they are extensively added in products for occupational use. The goal of this study is to investigate the contact allergy patterns in order to understand the linkage among hypersensitivity to preservatives, occupational profiles, patients' clinical and demographic characteristics. Patch test results were collected from monosensitized patients to Formaldehyde 2%, KATHON 0.02%, thimerosal 0.1%, and MDBGN 0.5%; information was also collected for an extended MOAHLFA (Male-Occupational-Atopic-Hand-Leg-Face-Age) index. To assess the relationship between allergen group and occupational-related ACD, the chi-square test for independence was utilized. To uncover underlying relationships in the data, multiple correspondence analysis (MCA) and categorical principal components analysis (CATPCA), which are machine learning approaches, were applied. Significant relationships were found between allergen group and: occupation class, atopy, hand, leg, facial, trunk, neck, head dermatitis, clinical characteristics, ICDRG 48 h and ICDRG 72 h clinical evaluation. MCA and CATPCA findings revealed a link among allergen group, occupation class, patients' demographic and clinical characteristics, the MOAHLFA index, and the ICDRG scores. Significant relationships were identified between the allergen group and various manifestations of dermatitis. The utilization of machine learning techniques facilitated the discernment of meaningful patterns in the data.

BACKGROUND: Due to an increasing occupational usage of isothiazolinone (IT)-containing preservatives, and their potential to cause skin sensitization and allergic contact dermatitis, that is, chronic disease, there is a need for more knowledge on how highly exposed workers are affected. OBJECTIVES: The overall objective was to explore dermatological symptoms of potentially long-lasting or chronic character in Swedish painters. METHODS: Building painters from western and southern Sweden were initially invited to perform a questionnaire on occurrence of skin symptoms. Participants with affirmative responses, and the right inclusion criteria, were further invited to patch testing with four different ITs: benzisothiazolinone (BIT), methylisothiazolinone, methylchloroisothiazolinone and octylisothiazolinone. RESULTS: There was a tendency towards higher occurrence of positive patch test reactions among the painters compared with occupationally unexposed registry patients; however, not statistically significant differences. BIT was the substance most frequently causing positive test results in both groups. The occurrence of adult-onset eczema was higher in painters than in the control group of electricians, and just shy of statistical significance concerning any of several skin locations (face/legs/arms/hands). CONCLUSION: Building painters present with positive patch test reactions to common paint preservatives (ITs), and they report adult-onset eczema more often than do less occupationally exposed groups.

BACKGROUND/OBJECTIVES: In the last 10 years methylisothiazolinone (MI) emerged as a global cause of preservative-related ACD. New Zealand has liberal regulations for the MI concentration limit in cosmetic products compared to Europe and Australia. The aim of this study was to evaluate the prevalence of MI sensitisation in New Zealand, explore sources of MI exposure and make recommendations on New Zealand regulations for MI use. METHODS: This retrospective study included data from patients who underwent patch testing with MI from 2008 to 2021 in a tertiary hospital dermatology clinic and a private dermatology clinic in Auckland, New Zealand. Patient baseline characteristics were recorded along with results of patch testing. Sources of MI exposure were identified from medical records. RESULTS: Over the study period, 1049 patch tests were performed in 1044 patients. MI was only tested as a stand-alone allergen from 2015; positive reactions to MI increased from 5.3% in 2015 to a peak of 11.9% in 2017 and then decreased to 6.4% in 2021. The most common source of MI exposure was shampoo or conditioner (27.7% of all relevant reactions) followed by occupational exposures to paints, biocides or glue (19.1%). CONCLUSION: Both sensitisation and ACD to MI appear to be decreasing, likely secondary to changes in product compounding due to stricter concentration limits internationally. We recommend New Zealand adopt lower MI concentration limits for cosmetics to match the limits of Australia and Europe.

BACKGROUND: Earlier studies suggested a potential association between tobacco smoking and nickel sensitization, but little is known about other contact allergens. OBJECTIVES: To investigate the association of smoking status and contact sensitizations as well as subtypes of dermatitis, and to analyse the sensitization profiles of tobacco smokers. PATIENTS AND METHODS: Within the Information Network of Departments of Dermatology (IVDK), we performed a cross-sectional multicentre pilot study comprising 1091 patch-tested patients from 9 departments, comparing 541 patients with a history of cigarette smoking (281 current and 260 former smokers) with 550 never-smokers. RESULTS: We could not confirm the previously reported association between nickel sensitization and tobacco smoking. Moreover, sensitizations to other allergens, including colophony, fragrance mix I, Myroxylon pereirae and formaldehyde, were not increased in cigarette smokers compared with never smokers. Hand dermatitis (50.6% vs. 33.6%) and occupational cause (36.2% vs. 22.5%) were significantly more frequent among cigarette smokers compared with never-smokers as shown by non-overlapping 95% confidence intervals. CONCLUSIONS: Although our study does not allow a firm conclusion on whether smoking status contributes to certain contact sensitizations, it confirms an association of smoking with hand dermatitis and occupational cause.

BACKGROUND: Healthcare workers are at high risk of developing occupational hand dermatitis (HD) due to their frequent exposure to wet-work and use of gloves. Complaints of HD may interfere with work and cause loss of work productivity, or sick leave, and may have impact on job pleasure and performing daily activities. The prevalence of HD among intensive care unit (ICU) nurses is unknown. OBJECTIVES: To investigate the point prevalence and the 1-year prevalence of HD among ICU nurses, and to determine the impact of HD on work and daily activities. METHOD: A questionnaire-based cross-sectional study was performed among ICU nurses. Participants were recruited in the Amsterdam University Medical Centre. A symptom-based questionnaire was used to determine HD and atopic predisposition, and an additional questionnaire was used concerning the influence of HD. ICU nurses with an atopic predisposition or symptoms suiting HD were invited for the hand dermatitis consultation hour (HDCH). Data were analysed with logistic regression. RESULTS: A total of 184 ICU nurses were included. The point prevalence of HD was 9.8% (95% CI: 5.9-15.0) and the 1-year prevalence was 26.6% (95% CI: 20.4-33.6). Sick leave was reported by 0.5%. HD seemed to have more impact on job pleasure than on work productivity. CONCLUSION: The high prevalence rate of HD resulting from our study highlights the need for the prevention of occupational HD among healthcare workers.

BACKGROUND: Artificial nail modelling systems (ANMS) pose a significant risk for nail stylists and their clients regarding acrylate sensitization, which might jeopardize the use of acrylate-containing medical devices. OBJECTIVES: To evaluate the frequency of artificial nail practices among female healthcare workers (HCWs) compared with controls and assess ANMS-related side effects. METHODS: In this comparative, cross-sectional, single-centre study, a face-to-face interview with 200 female HCWs and 200 age-matched female dermatology patients (controls) was conducted regarding the use of ANMS between March and November 2023. RESULTS: Among 400 participants (median age: 25), 85 (21.3%) have applied ANMS at least once. The prevalence of ANMS application was significantly higher in HCWs (n = 54/200, 27%) compared with controls (n = 31/200, 15.5%) (p < 0.05). Long-lasting nail polish was the most commonly preferred technique (n = 82/85, 96.5%). ANMS were mainly performed in nail studios by nail stylists (n = 79/85, 92.9%), while three participants were using home kits. Nail brittleness was the most frequently reported side effect (n = 19/85, 22.4%). No case of allergic contact dermatitis (ACD) was detected. CONCLUSIONS: The popularity of ANMS among young female HCWs is growing. This striking trend might further put these individuals not only at risk of medical device-related adverse events but also occupational ACD.

Timely intervention reduces the risk of a poor prognosis in hand eczema, making early recognition of symptoms important in high-risk professions. However, limited data exist regarding the ability of cleaners and healthcare workers to recognize hand eczema. The aim of this study was to examine cleaners' and healthcare workers' ability to recognize hand eczema in clinical photographs and to assess the severity of the disease. Cleaners and healthcare workers completed a questionnaire consisting of 16 questions and participated in a structured interview referring to a validated photographic severity guide for chronic hand eczema, which comprised clinical photographs of hand eczema at varying levels of severity. Eighty cleaners and 201 healthcare workers (total N = 281) participated in the study. The rates of correctly identified hand eczema in clinical photographs (cleaners/ healthcare workers) were: 41.2%/57.7% (mild hand eczema), 81.2%/92.0% (moderate hand eczema), 85.0%/94.5% (severe hand eczema) and 82.5%/97.0% (very severe hand eczema). The proficiency of healthcare workers in recognizing hand eczema was significantly higher than that of cleaners. The results indicate that a large proportion of cleaners and healthcare workers fail to recognize mild hand eczema in clinical photographs. Healthcare workers had higher success rates in recognizing hand eczema in all severity categories. Symptom underestimation may lead to under-reporting of the true prevalence of hand eczema, with consequent loss of opportunities for prevention.

BACKGROUND: Professional ice hockey players may contract irritant and allergic contact dermatitis. AIMS: To investigate the presence of contact allergy (CA) in professional ice hockey players in Sweden. METHODS: Ten teams from the two top leagues were assessed for potential occupational exposure to sensitizers. Exactly 107 players were patch tested with an extended baseline series and a working series, in total 74 test preparations. The CA rates were compared between the ice hockey players and controls from the general population and dermatitis patients. RESULTS: One out of 4 players had at least one contact allergy. The most common sensitizers were Amerchol L 101, nickel and oxidized limonene. CA was as common in the ice hockey players as in dermatitis patients and significantly more common than in the general population. Fragrances and combined sensitizers in cosmetic products (fragrances + preservatives + emulsifier) were significantly more common in ice hockey players compared with the general population. CONCLUSION: The possible relationship between CA to fragrances and cosmetic products on the one hand and the presence of dermatitis on the other should be explored further.

BACKGROUND: During the COVID-19 pandemic, increased hand hygiene practices were implemented. Impaired skin health on the hands among healthcare workers has been reported previously. Knowledge of how worker in other occupations have been affected is scarce. OBJECTIVES: To investigate self-reported hand water-, and soap exposure and use of hand disinfectants, and hand eczema (HE) in frontline workers outside the hospital setting and in IT personnel during the COVID-19 pandemic. METHODS: In this cross-sectional study, a questionnaire was sent out between 1 March and 30 April in 2021, to 6060 randomly selected individuals representing six occupational groups. RESULTS: A significant increase in water exposure and hand disinfectant use was shown: Relative position (RP) 19; 95% confidence interval (CI) 0.17-0.21 and RP = 0.38: 95% CI 0.36-0.41, respectively. Newly debuted HE was reported by 7.4% of the population, more frequently among frontline workers (8.6%) compared to IT personnel (4.9%). CONCLUSIONS: Water and soap exposure and use of hand disinfectants increased during COVID-19 pandemic, which may increase the risk of hand eczema. This highlights the importance of communication and implementation of preventive measures to protect the skin barrier also in occupations other than healthcare workers.

OBJECTIVES: Self-reported hand eczema was previously found under-reported as an occupational disease to the authorities among Danish hairdressers graduating from 1985 to 2007. This study investigates whether self-reported hand eczema among Danish hairdressers graduating from 2008 to 2018 is under-reported as an occupational disease to the authorities. METHODS: A cross-sectional study on all Danish hairdressers graduating from 2008 to 2018 was conducted. The participants were identified using information from the Danish Hairdressers' and Beauticians' Union. In May 2020, a self-administered survey on hand eczema was sent to all hairdressers. RESULTS: A response rate of 30.7% (1485/4830) was obtained. The lifetime prevalence of self-reported hand eczema was 40.1%, and 84.1% of hairdressers with hand eczema believed it to be occupational of whom 27.0% answered it was reported as an occupational disease to the authorities. Of hairdressers believing their hand eczema was occupational, consulting a doctor and answering it was reported as an occupational disease, 94.4% had consulted a dermatologist. The main reason for not reporting was 'I would probably not gain anything from it anyway' (40.0%). CONCLUSIONS: Based on hairdressers' perception, occupational hand eczema still seems to be an under-reported disease which may lead to underestimation of the problem and impair prevention, diagnosis and treatment.

Healthcare workers (HCWs) are considered a high-risk group for developing hand eczema (HE), mainly owing to wet work and contact with allergens at work. To meta-analyse the prevalence and incidence of HE in HCWs, as well as mapping the prevalence of atopic dermatitis (AD) and HE severity in HCWs. A systematic review and meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 guidelines. Published literature from 2000 to 2022 was eligible based on predefined inclusion and exclusion criteria. A total of 18 studies were included. Pooled life-time, 1-year and point prevalence of self-reported HE in HCWs was 33.4% (95% confidence interval [CI]: 28.3-38.6), 27.4% (95% CI: 19.3-36.5) and 13.5% (95% CI: 9.3-18.4), respectively. AD prevalence was 15.4% (95% CI: 11.3-19.9). Overall, the majority of HCWs reported mild HE. One included study assessed HE incidence reporting 34 cases/1000 person years. Most studies scored low-moderate using the New Ottawa Scale and the pooled point prevalence data showed broad CIs. In conclusion, the high prevalence of HE in HCWs underlines the increased risk and need for preventive measures for this professional group. There is, however, a need of further standardized high-quality studies.

BACKGROUND: Occupational skin disease (OSD), such as contact dermatitis, is widespread among dental professionals; however, reports regarding its prevalence have inconsistent findings and methodology. Therefore, we conducted a cross-sectional survey using a self-reported questionnaire to estimate the prevalence of work-related and occupational exposure-induced skin diseases. METHODOLOGY: A self-administered questionnaire, based on the validated Nordic Occupational Skin Questionnaire-2002, was distributed to 15 dental clinics in Israel in the first half of 2022. The questionnaire included questions about the occupation, exposure, and history of atopic disease, dry skin, and hand/arm and wrist eczema, as well as participant demographics. RESULTS: Overall, 312 dental professionals completed the questionnaires. Response rate was 80%. The lifetime prevalence of self-reported skin symptoms was 19.23%. Significant risk factors included exposure to metal objects, odds ratio (OR): 2.43, 95% confidence interval (CI): [1.02, 5.78]; p < .05, dry skin (OR: 3.54, 95% CI: [1.93, 6.5]; p < .001), itching when sweating (OR: 2.89, 95% CI: [1.39, 6]; p < .05), contact urticaria (OR: 10.67, 95% CI: [4.46, 25.49]; p < .001), hay fever (OR: 2.25, 95% CI: [1.14, 4.42]; p < .05), allergic symptoms (OR; 2.33, 95% CI: [1.18, 4.58]; p < .05), and asthma (OR: 4.8, 95% CI: [2.17, 10.36]; p < .001). CONCLUSIONS: This is the first study to use the NOSQ-2002 among dental professionals. Our study provides a better understanding of the prevalence and consequences of OSDs among dental personnel by utilizing the validated tool NOSQ-2002.

BACKGROUND: Occupational contact dermatitis (OCD) is a common occupational disease. Atopic dermatitis (AD) is a known risk factor for OCD. OBJECTIVES: To determine the prevalence of previously diagnosed AD among young workers with recognized OCD and assess its impact on OCD prognosis. METHODS: A retrospective cohort study. A questionnaire was sent to 6251 workers with recognized OCD who were under 35 years at notification (response rate: 47%). Of the respondents, 2392 answered a question about previous doctor-diagnosed AD and were included in the study. Eczema severity, occupational consequences and quality of life were examined using statistical analyses comparing workers with and without previously diagnosed AD. RESULTS: The prevalence of previously diagnosed AD was 41.8% (95% CI: 39.8-43.8). Women had a higher AD prevalence, and workers with AD reported OCD at a younger age. Workers with AD reported more frequent and severe eczema symptoms and had a higher risk of OCD negatively affecting job and occupation choices. Health-related quality of life was more adversely affected in workers with AD. CONCLUSIONS: AD significantly impacts severity and has long-term consequences for young people with OCD. Targeted prevention strategies need to be developed.

BACKGROUND: Isothiazolinones are a common cause of allergic contact dermatitis. OBJECTIVE: To examine the prevalence of positive patch test reactions to isothiazolinones from 2017-2020 and characterize isothiazolinone-allergic (Is+) patients compared with isothiazolinone nonallergic (Is-) patients. METHODS: Retrospective cross-sectional analysis of 9028 patients patch tested to methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI) 0.02% aqueous, MI 0.2% aqueous, benzisothiazolinone (BIT) 0.1% petrolatum, and/or octylisothiazolinone (OIT) 0.025% petrolatum. Prevalence, reaction strength, concurrent reactions, clinical relevance, and source of allergens were tabulated. RESULTS: In total, 21.9% (1976/9028) of patients had a positive reaction to 1 or more isothiazolinones. Positivity to MI was 14.4% (1296/9012), MCI/MI was 10.0% (903/9017), BIT was 8.6% (777/9018), and OIT was 05% (49/9028). Compared with Is-, Is+ patients were more likely to have occupational skin disease (16.5% vs 10.3%, P <.001), primary hand dermatitis (30.2% vs 19.7%, P <.001), and be >40 years (73.1% vs 61.9%, P <.001). Positive patch test reactions to >1 isothiazolinone occurred in 44.1% (871/1976) of Is+ patients. Testing solely to MCI/MI would miss 47.3% (611/1292) of MI and 60.1% (466/776) of BIT allergic reactions. LIMITATIONS: Retrospective cross-sectional study design and lack of follow-up data. CONCLUSION: Sensitization to isothiazolinones is high and concurrent sensitization to multiple isothiazolinone allergens is common.

PURPOSE OF REVIEW: Occupational allergic contact dermatitis (OACD) is an important work-related skin disease. Information about the causative agents comes from many sources, including patch test databases, registries, case series and case reports. This review summarizes new information about common causative allergens and diagnosis. RECENT FINDINGS: Common causes of OACD include rubber components, epoxies and preservatives. New exposure sources for these allergens continue to be described. Often these exposure sources are related to the changing world around us, such as allergens related to smartphones and technology, and personal protective equipment-related exposures during the COVID-19 pandemic. New allergens are also being described, some of which are related to known allergens (e.g. a new epoxy or acrylate component).Accurate diagnosis is critical to effective management of OACD, which may include removing the worker from exposure to the causative allergen. Safety data sheets may not contain complete information and patch testing with specialized series of allergens and workplace materials may be necessary. SUMMARY: This review provides current evidence about causes of OACD and important aspects of diagnosis. This is important for clinical practice to ensure cases of OACD are not missed.

BACKGROUND: Ethylenediamine dihydrochloride is a versatile aliphatic amine found in numerous medications and industrial compounds and is a known sensitiser. The sensitization prevalence is affected by geographical and socio-cultural factors. OBJECTIVES: The objectives are to analyse the temporal trend of sensitization to ethylenediamine dihydrochloride in northeastern Italy and to investigate associations with occupations. METHODS: Between 1996 and 2021, 30 629 patients with suspected allergic contact dermatitis were patch tested with the Triveneto baseline series. Individual characteristics were collected through a standardised questionnaire. RESULTS: The overall prevalence of ethylenediamine dihydrochloride sensitization was 1.29% with percentages similar in both sexes. We observed a significant decreasing trend over time (p < 0.001), yielding a sensitization prevalence <1% in recent years. Among departments, residence in Pordenone area was protective for sensitization. No significant associations were observed with specific occupations. We found significant associations between ethylenediamine dihydrochloride sensitization and being 26-35 years old (odds ratio [OR], 1.47; 95% confidence interval [CI]: 1.05-2.08), and sensitization for many haptens, such as paraben mix (OR, 5.3; 95% CI: 3.3-8.5), epoxy resin (OR, 5.1; 95% CI: 3.0-8.7), neomycin sulphate and mercaptobenzothiazole. CONCLUSIONS: Our study showed a downward time trend of ethylenediamine dihydrochloride sensitization in northeastern Italian population and pointed to an update of the Triveneto baseline series.

BACKGROUND: Occupational exposure to metals such as nickel, chromium and cobalt can be associated with contact dermatitis, which can adversely affect an individual's health, finances and employment. Despite this, little is known about the incidence of metal-related occupational contact dermatitis over prolonged periods of time. OBJECTIVES: To investigate the medically reported trends in the incidence of work-related contact dermatitis attributed to nickel, chromium and cobalt in the UK. METHODS: Incidence and trends in cases of occupational contact dermatitis caused by nickel, chromium or cobalt between 1996 and 2019 (inclusive), reported to the EPIDERM surveillance scheme, were investigated and compared with trends in the incidence of occupational contact dermatitis attributed to agents other than the aforementioned metals. A sensitivity analysis restricting the study cohort to cases attributed to only one type of metal was also conducted. RESULTS: Of all cases reported to EPIDERM during the study period, 2374 (12%) were attributed to nickel, chromium or cobalt. Cases predominantly comprised females (59%), with a mean (SD) age (males and females) of 38 (13) years. Cases were most frequently reported in manufacturing, construction, and human health and social activity industries. The most frequently reported occupations were hairdressing, and sales and retail (assistants, cashiers and checkout operators). The highest annual incidence rate of contact dermatitis was observed in females (2.60 per 100 000 persons employed per year), with the first and second peak seen in those aged 16-24 and ≥ 65â years, respectively. A statistically significant decrease in the incidence of occupational contact dermatitis attributed to metals over the study period was observed for all occupations (annual average change -6.9%, 95% confidence interval -7.8 to -5.9), with much of the decrease occurring between 1996 and 2007. Similar findings were obtained in the sensitivity analyses. CONCLUSIONS: Over a period of 24â years, there has been a statistically significant decline in the incidence of metal-related occupational contact dermatitis in the UK. This could be attributed not only to improvements in working conditions, which have reduced metal exposure, but could also be due to the closure of industries in the UK that might have generated cases of contact dermatitis owing to metal exposure.
