Hand eczema symptoms, exposures and skin care in orthodontics : A national, cross-sectional questionnaire-based survey.

OBJECTIVES: Occupational hand eczema is a common inflammatory skin condition among healthcare professionals. Orthodontists are frequently exposed to a variety of irritating and allergenic substances, and therefore they belong to a predisposed group to develop hand eczema. However, current data on the prevalence and predisposing factors among orthodontists to provide adequate prophylaxis are lacking. METHODS: An anonymous online survey was conducted in Germany between January and February 2023 and distributed to 2402 orthodontists. The questionnaire addressed general information on current skin status, as well as occupational skin exposure and skin care. RESULTS: A total of 209 orthodontists responded to the survey. Seventy-four percent reported experiencing hand eczema-specific symptoms within the last 12 months, with 24% describing moderate and 10% describing severe symptoms. The average daily glove wearing time was stated to be 6 ± 2 h. The most frequently reported triggers at work were frequent hand washing (62.7%) and hand disinfection (59.1%). Among all the respondents, 22.6% stated not using either barrier cream or moisturizer. CONCLUSIONS: This study showed a high prevalence of hand eczema symptoms among orthodontists, which is probably due to frequent disinfection, hand washing, and contact with allergens such as acrylates. In this professional group especially, against a background of future increasing acrylate and epoxy resin exposures due to in-office three-dimensional printing processes, timely education and skin protection could decisively counteract the pathogenesis of hand eczema.

Hand eczema and skin complaints in particulate matter-exposed occupations - firefighters, chimney sweepers, and ferrosilicon smelter workers in Norway.

BACKGROUND: The objective was to investigate self-reported hand eczema, and skin complaints at other skin locations among workers exposed to particulate matter, especially ultrafine particles. METHOD: We conducted a cross-sectional study on workers from one ferro-silicon smelter plant, eight chimney sweeper stations and one firefighter station across Norway. Participants answered an extended version of the Nordic Occupational Skin Questionnaire (NOSQ-2022), with additional questions about whole-body skin complaints and visible dust deposition. Results are presented as descriptive data using firefighters as reference group. Odds ratio (OR) was calculated using logistic regression on lifetime prevalence of hand eczema adjusted for potential confounders and mediators. P-values were calculated using likelihood ratio test against the crude OR. RESULTS: A total of 186 participants answered the questionnaire: 74 chimney sweepers, 52 firefighters and 60 smelter workers. Participation rate was 95.0, 94.5 and 63.6%, respectively. Lifetime prevalence of hand eczema was 9.5, 9.6, and 28.3%, respectively. The point prevalence of hand eczema was 1.4, 1.9 and 10.0%, respectively. We estimated OR for lifetime hand eczema in smelter workers to 4.36 [95% CI: 1.31-14.43, p = 0.016] and for lifetime skin complaints in other locations to 2.25 [95% CI: 0.98-5.18, p = 0.058]. The lifetime prevalence of skin complaints at other locations was 18.9, 23.1 and 40.0%, respectively. The point prevalence was 14.9, 9.6 and 16.7%, respectively. These estimates were not statistically significant but indicates that smelter workers have more skin complaints also at other locations. CONCLUSION: This study reports a more than four-fold increased risk of hand eczema in smelter workers, and possibly a higher risk of skin complaints in other body locations, compared to the other occupations. Longitudinal studies with larger population are needed to verify the marked increased risk of eczema among smelters and establish causation.

Contact allergy caused by acrylates in nail cosmetics: A pilot study from Greece.

BACKGROUND: The growing popularity of nail techniques based on acrylates has led to a higher frequency of sensitization in both nail technicians and users. OBJECTIVES: The study aimed to assess cases of allergic contact dermatitis (ACD) caused by acrylates in individuals with occupational or non-occupational exposure to nail techniques. METHODS: A preliminary study was conducted on 30 patients with ACD caused by acrylates in nail techniques, who were patch tested from September 2022 to March 2023 at the First Department of Dermatology and Venereology of Andreas Syggros Hospital, Athens, Greece. RESULTS: Thirty female patients with ACD to acrylates were documented (15 users and 15 nail technicians and users). The most common allergens were: 2-hydroxyethyl methacrylate (HEMA), 2-hydroxypropyl methacrylate (HPMA) and ethyleneglycol dimethacrylate (EGDMA), which tested positive in all 30 patients (100.0%). Twenty patients (66.7%) had been exposed to dental procedures involving acrylates, before the onset of ACD. Nail technicians exhibited extensive skin lesions, 40.0% experienced ACD within the first year of work and 13.3% during their professional practice. Three of them (20.0%) had to discontinue their work. CONCLUSION: Acrylates have been identified as potent allergens, necessitating the implementation of safety measures for the use of these chemicals in nail techniques.

Occupational Exposure of Employees in a Multispecialty Hospital to Factors Causing Contact Dermatitis-A Questionnaire Study.

Background and Objectives: Allergic contact dermatitis (ACD) is a serious health and socio-economic problem. Accurate and reliable assessment of exposure to ACD factors in the work environment would increase quality of life and work of employees. The aim of this study was to assess the level of exposure of workers of a multidisciplinary hospital to the factors causing ACD. Material and Methods: The proprietary OSDES-16 questionnaire was used. The effectiveness of the OSDES-16 was confirmed statistically. The study included 230 employees of the medical center in Polanica Zdrój, divided into groups. Results: The differences in the overall assessment of exposure between the individual groups in the OSDES-16 scale were statistically insignificant (p > 0.05). There was no significant correlation between the current workplace and the level of exposure to ACD (p > 0.05). The level of exposure to ACD in the group of employees with work experience in the current position for more than 10 years was significantly higher than those working less than 6 years (p < 0.05). Conclusions: Nurses, midwives and paramedics are the occupational group most exposed to the development of contact allergy related to exposure to factors present in the work environment. The seniority of more than 10 years in the current position was linked with a higher level of occupational exposure.

Dermatological adverse effects of hair dye use: A narrative review.

Hair dyeing is a popular practice dating back to ancient Egyptian times. Initially, hair dye use was restricted to concealing grey and white hairs of the elderly population. However, in recent times, its use is common among the younger generation as a fashion statement. Hair dye contact dermatitis is a common dermatological condition encountered by dermatologists. It is a delayed type of hypersensitivity reaction that commonly affects the scalp and the vicinity of hair line and neck. Para-phenylenediamine (PPD), a synthetic aromatic amine is the most common allergen specifically implicated in hair dye contact dermatitis. Para-phenylenediamine was announced as the allergen of the year in 2006 by the American Contact Dermatitis Society. Contact allergy to para-phenylenediamine can occur in 0.1-2.3% of the general population. Epicutaneous patch testing is the gold standard test for the diagnosis of hair dye contact dermatitis. However, para-phenylenediamine carries a risk of cross-sensitivity and co-sensitization to other allergens. Apart from contact dermatitis, hair dye use is also associated with various other cutaneous adverse effects such as pigmentary changes, hair loss, skin malignancies and autoimmune disorders. Due to the various adverse effects associated with hair dye use, it is prudent to look for safer alternatives to allergenic hair dyes. In this article, we review the epidemiology, cutaneous and systemic adverse effects associated with hair dye use, patch testing, preventive strategies to minimize the risk of hair dye contact dermatitis, and treatment aspects.

[Patient education in work-related hand eczema : Importance and challenges in health care practice]. / Patientenschulungen bei berufsbedingten Handekzemen : Bedeutung und Herausforderungen in der Versorgungspraxis.

Patient education can help patients with work-related hand eczema to cope with their skin disease in an informed and responsible manner and to improve their personal skin protection behavior in everyday working and private life. Skin protection education in centers specialized in occupational dermatology is a pivotal component of outpatient and inpatient individual prevention programs for individuals with work-related skin diseases provided by the statutory accident insurance institutions in Germany. Patient education should be patient-oriented and promote learning, e.g., through interactive, activating discussions and design, references to everyday life, and methodically and didactically well-prepared media and materials in clear, understandable language. Challenges may arise in educational practice, e.g., due to subjective illness perceptions, participants with a lack of motivation, language barriers, functional illiteracy, or heterogeneous patient groups. In this article, different challenges are presented and educational and health psychological perspectives are discussed to meet these challenges in order to provide an optimal, patient-oriented individual prevention measure.

Occupational Hand Dermatitis.

PURPOSE OF REVIEW: Occupational hand dermatitis is a common work-related disorder of the skin. Prevention and management of this disease is critical to improving workers' quality of life and for occupation-specific retention. RECENT FINDINGS: This is a critical review of the current literature on occupational hand dermatitis. Occupational dermatitis continues to have a high prevalence among workers although the overall incidence may be slowly decreasing. Irritant contact dermatitis due to wet work exposure is the most common cause of occupational hand dermatitis. Healthcare workers, hairdressers, and metal workers are at particularly high risk for this disease. While some prevention programs have been ineffective in mitigating occupational hand dermatitis, other more resource-intensive initiatives may have benefit. Continued research is needed on ways to manage wet work exposures and on scalable, effective prevention programs for occupational hand dermatitis. The spectrum of culprit contact allergens continues to evolve, and vigilance for potential occupation-specific allergens remains important.

Occupational Chronic Hand Dermatitis in Hospital Environment Successfully Treated with Dupilumab: A Case Report.

Duplilumab is approved to treat mild to moderate atopic dermatitis.  It is unclear, however, whether Dupilumab is effective for occupational hand eczema. In this article, we describe a 29-year-old nurse who developed severe hand eczema after working in a hospital for 6 years and received inadequate relief from routine treatment. Duplilumab was administered to the patient with great results.

Improving Recovery of Irritant Hand Dermatitis in Healthcare Workers With Workplace Interventions During the COVID-19 Pandemic.

Introduction: Occupational hand dermatitis is common among healthcare workers, with increased incidence during the COVID-19 pandemic. Irritant contact dermatitis accounts for the majority of occupational hand dermatitis and is largely due to frequent contact with hand hygiene products. Long-term prognosis of occupational contact dermatitis is often very poor. This study aims to identify and implement suitable workplace interventions to aid in the recovery of occupational irritant hand dermatitis among healthcare workers during the COVID-19 pandemic. Methods: A quality improvement (QI) project was performed in a tertiary hospital using the Plan-Do-Study-Act model. Healthcare workers seen at the Occupational Dermatology Clinic from March 2020 to May 2021 for the first time for likely occupational irritant dermatitis were targeted for the project. Four workplace interventions were implemented: (a) substitute current alcohol-based hand rub (ABHR) with a different, gentler ABHR, (b) alternate ABHR with gentle hand wash products, (c) temporary job modification with less clinical work (d) switch latex gloves to nitrile gloves. The improvement was assessed after 2 months of workplace intervention using a visual analogue scale, based on changes seen on photographs taken at the baseline and monthly review. The target improvement was set at 70% after 2 months of workplace interventions. Results: A total of 21 participants were included in the QI project. All participants were found to have significant improvement in their hand condition. The estimated mean reduction of signs and symptoms was 80% in comparison to their baseline hand condition before intervention. Conclusion: Workplace interventions such as substituting irritant hand hygiene products with gentler alternatives and temporary reduction in clinical duties may be useful in improving the recovery rate of irritant hand dermatitis among healthcare workers. Areas with high hand hygiene workload or high incidences of hand dermatitis may opt to implement systemic workplace changes.

Nickel dust-induced occupational contact dermatitis by welding and grinding work in shipyard workers: a report of nine cases.

Background: Occupational skin diseases are skin conditions that occur or worsen in relation to work and known to be the second most common type of occupational disease affecting individuals in the United States. In Korea, epidemiological reports related to occupational skin diseases are rare. But, no cases of occupational contact dermatitis caused by welding and grinding work have been reported previously. Case presentation: Nine male workers working in the production department for liquefied natural gas (LNG) ships in Ulsan complained of erythematous papules/patches and itching in various areas of the body after welding and grinding work. The work environment monitoring report revealed that the amount of nickel dust exceeded the time weighted average (TWA) and poor local ventilation status. Based on the symptoms and the overall results of surveys, several tests, and work environment monitoring report, the 2 workers who had positive patch-test reactions to nickel were diagnosed with nickel dust-induced allergic contact dermatitis. The other 7 workers were diagnosed that there was a high probability that they had nickel dust-induced irritant contact dermatitis. The 2 workers who had nickel dust-induced allergic contact dermatitis were recommended to switch their jobs. Conclusions: Nickel is one of the most common cause of allergic contact dermatitis. In this case, the dust was assumed to be created by welding work with a high nickel content new welding rod and subsequent grinding work, and the concentration of this dust exceeded the time weighted average. Thus, it is thought that the nickel dust may have caused contact dermatitis through continuous contact with the workers' exposed skin in a poorly ventilated space. Currently, several domestic shipbuilding companies are manufacturing LNG tankers using a new construction method. Consequently, it is highly likely that similar cases will occur in the future, which makes this case report meaningful.

Adverse skin reactions among health care workers using face personal protective equipment during the coronavirus disease 2019 pandemic: A cross-sectional survey of six hospitals in Denmark.

BACKGROUND: Health care workers (HCWs) report frequent adverse skin reactions (ASRs) due to face personal protective equipment (F-PPE) use during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVES: To describe self-reported ASRs among HCWs using F-PPE; investigate background factors, such as chronic skin diseases and skin types (dry, oily, combination, sensitive), and determine whether HCWs took preventive methods against ASRs. METHODS: An online questionnaire was distributed to 22 993 HCWs at hospitals. RESULTS: The prevalence of ASRs was 61.9% based on 10 287 responders. Different types of F-PPE caused different reactions. The most common ASRs from surgical masks were spots and pimples (37.2%) and from FFP3 masks was red and irritated skin (27.3%). A significantly higher proportion of HCWs with chronic skin diseases had ASRs (71.6%) than those without chronic skin diseases (59.7%) (P < .001). Some skin types were more prone to ASRs (sensitive skin [78.8%] vs dry skin [54.3%]; P = .001). HCWs using F-PPE for >6 hours versus <3 hours per day had a four times higher ASR risk (P = <.001). Nearly all HCWs used preventive and/or counteractive methods (94.2%). CONCLUSIONS: It is important to consider background factors, such as chronic skin diseases and skin types, to prevent and counteract ASRs due to F-PPE use.

Quality of Life of Healthcare Workers Suffering from Occupational Contact Dermatitis.

BACKGROUND: Healthcare workers are at a high risk of developing Occupational Dermatitis (OD). Affected workers often experience severe impairment of their Quality of Life (QoL). This study aimed to assess the skin-related QoL of healthcare workers with OD and to explore its related factors. METHODS: A cross-sectional and exhaustive study was conducted among healthcare personnel of four public hospitals in the central region of Tunisia. All the cases of OD declared were included. Skin-related QoL was assessed using the validated Tunisian version of the "Dermatology Life Quality Index" (DLQI). Some related patents have also been discussed. RESULTS: A total of 37 cases of OD were collected with an annual incidence of 4.2 cases per 10000 workers. The population was predominantly female (73%) and the mean age was 44.7±9.4 years. Nurses were the most represented occupational category (38%). Allergic contact dermatitis was the most frequent diagnosis (96%). The use of gloves was the most frequently reported occupational hazard (86%). The most frequently affected sites were hands (97%). The median score of DLQI was five. Multivariate analysis showed an association between the impairment of skin-related QoL and female gender (p = 0.04; OR = 19.3,84), exposure to disinfecting chemicals in the workplace (p = 0.01; OR = 17,306) and the absence of occupational reclassification (p = 0.01; OR = 21,567). CONCLUSION: About one-third of the population had an impaired quality of life. The score impairment was significantly related to the female gender, exposure to disinfecting chemicals and the absence of occupational reclassification.

Resumo Introdução: a metilisotiazolinona isolada ou associada à metilcloroisotiazolinona (Kathon CG) é um conservante relacionado à dermatite de contato alérgica ocupacional. Objetivos: avaliar o perfil demográfico e clínico dos casos ocupacionais de sensibilização a isotiazolinonas no município do Rio de Janeiro e descrever a presença desses preservativos em tintas nacionais. Métodos: estudo transversal baseado em informações de prontuários de trabalhadores submetidos a testes de contato entre 2013-2017. Descreveu-se a prevalência de características clínicas, demográficas e ocupacionais e utilizou-se um modelo não-ajustado para investigar a associação entre variáveis. Buscou-se a presença e a concentração de isotiazolinonas nas fichas de composição química de tintas nacionais. Resultados: dentre os 768 trabalhadores submetidos aos testes, 68 apresentavam dermatose ocupacional com resultado positivo para sensibilização à metilisotiazolinona/Kathon CG. As profissões mais acometidas foram as relacionadas a atividades domésticas e limpeza. Houve maior chance de sensibilização às isotiazolinonas nas mulheres e naqueles com acometimento das mãos e das pernas. Entre as 61 tintas avaliadas, 26 possuíam alguma isotiazolinona, sendo a metilcloroisotiazolinona a mais comum. Conclusões: a sensibilização às isotiazolinonas pode impactar a saúde do trabalhador e demanda maior vigilância com materiais de limpeza e cosméticos, assim como a discussão da regulação da composição de tintas comercializadas no país.

Abstract Introduction: methylisothiazolinone alone or associated with methylchloroisothiazolinone (Kathon CG) is a preservative related to occupational allergic contact dermatitis. Objectives: to evaluate the demographic and clinical profile of occupational cases of sensitization to isothiazolinones in the city of Rio de Janeiro and to describe the presence of these preservatives in national paints. Methods: cross-sectional study based on information from medical records of workers who underwent patch testing between 2013-2017. The prevalence of clinical, demographic and occupational characteristics was described and an unadjusted model was used to investigate the association between variables. We sought the presence and concentration of isothiazolinones in the chemical composition sheets of national paints. Results: among the 768 workers submitted to the tests, 68 had occupational dermatosis with a positive result for sensitization to methylisothiazolinone/Kathon CG. The most affected occupations were those related to domestic activities and cleaning. There was a greater likelihood of sensitization to isothiazolinones in women and in those with involvement of the hands and legs. Among the 61 paints evaluated, 26 had some isothiazolinone, with methylchloroisothiazolinone being the most common. Conclusions: sensitization to isothiazolinones can impact workers' health and demands greater vigilance on cleaning materials and cosmetics, as well as discussing the composition regulation of the paints sold in Brazil.

Skin Exposures, Hand Eczema and Facial Skin Disease in Healthcare Workers During the COVID-19 Pandemic: A Cross-sectional Study.

The COVID-19 pandemic has led to enhanced hygiene procedures and use of personal protective equipment, but also to increased attention to occupational skin disease in healthcare workers. The occurrence of hand and facial skin disease in > 5,000 Swedish healthcare workers was investigated in a questionnaire survey. Levels of skin exposure related to hygiene procedures and personal protective equipment were recorded. Caring for patients with COVID-19 entailed higher levels of wet work and face mask exposures, and was associated with higher 1-year prevalence of both hand eczema (36%) and facial skin disease (32%) compared with not being directly engaged in COVID-19 care (28% and 22%, respectively). Acne and eczema were the most common facial skin diseases; for both, a dose-dependent association with face mask use was found. Dose-dependent associations could be shown between hand eczema and exposure to soap and gloves, but not to alcohol-based hand disinfectants.
