Background: Physicians and dentists are at risk for chronic hand eczema, but their skin barrier condition has rarely been investigated before. Objective: To objectively assess the skin barrier condition among physicians and dentists. Methods: This cross-sectional epidemiological study included an occupational questionnaire, medical examination of hand skin, skin transepidermal water loss (TEWL), and pH measurements, analyzed in 5 groups (N = 37 in each): physicians-nonsurgeons, physicians-surgeons, dentists-nonsurgeons, dentists-surgeons, and control group (unexposed workers). Results: Critical skin condition (TEWL >30 g/[m2·h]) was found in 14% of control workers, 14% physicians nonsurgeons, 22% physicians surgeons, 27% dentists nonsurgeons, and 43% dentists surgeons. The latter had the worst stratum corneum condition indicated by a TEWL median of 25.80 g/(m2·h) (interquartile range [IQR] 19.24-34.31). Hand skin pH was highest among dentists with nonsurgical specializations, with a median of 5.33 (IQR 5.15-5.60), where 38% of them had pH >5.5. Male sex (P < 0.001) and glove use for >1 h/day (P = 0.009) were associated with elevated hand TEWL values, whereas female sex (P < 0.001) and glove use for >4 h/day with elevated pH values (P < 0.001). Conclusions: Prolonged glove usage and dental profession, especially surgical work, significantly affect the skin barrier condition. This study was the first to objectively determine skin barrier condition among dentists and physicians.

INTRODUCTION: Snakebite incidence varies across Europe. However, there is limited research from Central and Southeastern Europe. These regions are notable for the presence of the common European adder (Vipera berus) and the more venomous nose-horned viper (Vipera ammodytes). No standard European antivenom protocol exists. The aim was to assess the epidemiology and treatment of viper bites in this region, focusing on a comparison of bites from Vipera berus and Vipera ammodytes. METHODS: We conducted a prospective multicenter study in Central and Southeastern Europe from 2018 to 2020. This study included poison centres and toxicology-associated hospital wards in Poland, the Czech Republic, Slovakia, Hungary, Slovenia, Croatia, Serbia, and Bulgaria. The following data were collected: age, gender, Vipera species, snakebite site, clinical picture, laboratory results, Audebert's clinical severity grading score, and antivenom therapy. RESULTS: The annual incidence of viper bites in Central and Southeast Europe was estimated at 2.55 bites per million population. Within their respective geographical distribution areas, the incidence of Vipera ammodytes bites (1.61 bites per million population) was higher than Vipera berus bites (1.00 bites per million population). Patients bitten by Vipera ammodytes more frequently reported local pain and developed thrombocytopenia. Antivenom treatment was more commonly administered in Vipera ammodytes bites (72%) compared to Vipera berus bites (39%). The incidence of Vipera ammodytes bites treated with antivenom within its geographical distribution area was three times higher than Vipera berus bites treated with antivenom (1.16 bites per million population versus 0.39 bites per million population). No deaths were reported. CONCLUSIONS: The estimated incidence of viper bites in Central and Southeastern Europe is at least 2.55 per million population. Vipera ammodytes bites are more common and severe, characterized by higher frequencies of pain and thrombocytopenia. Antivenom is needed more often for Vipera ammodytes bites. It is vital that enough European Medicines Agency-approved Vipera ammodytes antivenom is produced and offered affordably.

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.

This systematic review, conducted according to the PRISMA guidelines, focuses on genotoxicity of oxidative hair dye precursors. The search for original papers published from 2000 to 2021 was performed in Medline, Web of Science, Cochrane registry, Scientific Committee on Consumer Safety of the European Commission and German MAK Commission opinions. Nine publications on genotoxicity of p-phenylenediamine (PPD) and toluene-2,5-diamine (p-toluylenediamine; PTD) were included, reporting results of 17 assays covering main genotoxicity endpoints. PPD and PTD were positive in bacterial mutation in vitro assay, and PPD tested positive also for somatic cell mutations in the Rodent Pig-a assay in vivo. Clastogenicity of PPD and PTD was revealed by in vitro chromosomal aberration assay. The alkaline comet assay in vitro showed DNA damage after PPD exposure, which was not confirmed in vivo, where PTD exhibited positive results. PPD induced micronucleus formation in vitro, and increased micronucleus frequencies in mice erythrocytes following high dose oral exposure in vivo. Based on the results of a limited number of data from the classical genotoxicity assay battery, this systematic review indicates genotoxic potential of hair dye precursors PPD and PTD, which may present an important health concern for consumers and in particular for professional hairdressers.

BACKGROUND: The burden of occupational hand eczema in hairdressers is high, and (partly strong) allergens abound in the hair cosmetic products they use. OBJECTIVES: To systematically review published evidence concerning contact allergy to an indicative list of active ingredients of hair cosmetics, namely, p-phenylenediamine (PPD), toluene-2,5-diamine (PTD), persulfates, mostly ammonium persulfate (APS), glyceryl thioglycolate (GMTG), and ammonium thioglycolate (ATG), concerning the prevalence of sensitization, particularly in terms of a comparison (relative risk; RR) between hairdressers and non-hairdressers. METHODS: Following a PROSPERO-registered and published protocol, eligible literature published from 2000 to February 2021 was identified, yielding 322 publications, and extracted in standardized publication record forms, also considering risk of bias. RESULTS: Based on 141 publications, the contact allergy prevalence to PPD was 4.3% (95% CI: 3.8-4.9%) in consecutively patch tested patients. Other ingredients were mostly tested in an aimed fashion, yielding variable, and partly high contact allergy prevalences. Where possible, the RR was calculated, yielding an average increased sensitization risk in hairdressers of between 5.4 (PPD) and 3.4 (ATG). Additional evidence related to immediate-type hypersensitivity, experimental results, exposures, and information from case reports was qualitatively synthesized. CONCLUSIONS: An excess risk of contact allergy is clearly evident from the pooled published evidence from the last 20 years. This should prompt an improvement in working conditions and product safety.

OBJECTIVES: To review recent epidemiological studies investigating carcinogenic or reprotoxic effects among hairdressers who seem to be at greater risk for systemic adverse effects of chemicals released from hair care products than consumers. METHODS: A systematic review according to the PRISMA-P guidelines was performed and included studies published from 2000 to August 2021, in which cancer or adverse reproductive effects were diagnosed in 1995 and onward. Data were synthetized qualitatively due to the small number of studies, heterogeneity of study designs, outcomes, and methods. RESULTS: Four studies investigating cancer frequencies and six studies investigating effects on reproduction among hairdressers were identified. All were of good quality and with low risk of bias. Only one of the four studies found an increased risk of cancer reporting nine times higher odds for bladder cancer in hairdressers than the population-based controls. Three other studies investigating bladder and lung cancer, and non-Hodgins lymphoma did not find an increased risk in hairdressers. Regarding reprotoxic effects, numerous outcomes were investigated including menstrual disorders, congenital malformations, fetal loss, small-for-gestational age newborns, preterm delivery, and infertility. Increased risk was found for ventricular septal defect in newborns of fathers working as hairdressers. Furthermore, several indices of poor neonatal or maternal health were significantly associated with mothers working as hairdresser. CONCLUSIONS: Despite the scarce evidence that hairdressers are at increased risk of carcinogenic or reprotoxic effects related to their trade, such health risks cannot be ruled out. Therefore, preventive efforts to diminish occupational exposures to hairdressing chemicals should be targeted.

The safety assessment of cosmetics considers the exposure of a 'common consumer', not the occupational exposure of hairdressers. This review aims to compile and appraise evidence regarding the skin toxicity of cysteamine hydrochloride (cysteamine HCl; CAS no. 156-57-0), polyvinylpyrrolidone (PVP; CAS no. 9003-39-8), PVP copolymers (CAS no. 28211-18-9), sodium laureth sulfate (SLES; CAS no. 9004-82-4), cocamide diethanolamine (cocamide DEA; CAS no. 68603-42-9), and cocamidopropyl betaine (CAPB; CAS no. 61789-40-0). A total of 298 articles were identified, of which 70 were included. Meta-analysis revealed that hairdressers have a 1.7-fold increased risk of developing a contact allergy to CAPB compared to controls who are not hairdressers. Hairdressers might have a higher risk of acquiring quantum sensitization against cysteamine HCl compared to a consumer because of their job responsibilities. Regarding cocamide DEA, the irritant potential of this surfactant should not be overlooked. Original articles for PVP, PVP copolymers, and SLES are lacking. This systematic review indicates that the current standards do not effectively address the occupational risks associated with hairdressers' usage of hair cosmetics. The considerable irritant and/or allergenic potential of substances used in hair cosmetics should prompt a reassessment of current risk assessment practices.

INTRODUCTION: Exposure to hazardous chemicals released during hairdressing activities from hair care products puts hairdressers at risk of adverse health effects. Safety assessments of hair products are mainly focused on consumers, but exposure for professional hairdressers might be substantially higher. OBJECTIVE: To identify and assess available research data on inhalation exposures of professional hairdressers. METHODS: A systematic search of studies between 1 January 2000 and 30 April 2021 was performed in Medline, Embase, Web of Science and in Cochrane registry, toxicological dossiers of the Scientific Committee on Consumer Safety (SCCS) of the European Commission as well as the German MAK Commission. Studies reporting quantitative data on airborne concentrations of chemicals in the hairdresser's workplace were considered. The outcome was an airborne concentration of chemicals in the working environment, which was compared, when possible, with current occupational exposure limits (OEL) or guidance levels. RESULTS: In total, 23 studies performed in 14 countries were included. The average number of hairdressing salons per study was 22 (range 1-62). Chemicals most frequently measured were formaldehyde (n = 8), ammonia (n = 5), total volatile organic compounds (TVOC) (n = 5), and toluene (n = 4). More than fifty other chemicals were measured in one to three studies, including various aromatic and aliphatic organic solvents, hydrogen peroxide, persulfate, and particulate matter. Most studies reported environmental air concentrations, while personal exposure was measured only in seven studies. The measured air concentrations of formaldehyde, ammonia, and TVOC exceeded OEL or guidance values in some studies. There was large variability in measuring conditions and reported air concentrations differed strongly within and between studies. CONCLUSION: Hairdressers are exposed to a wide spectrum of hazardous chemicals, often simultaneously. Airborne concentrations of pollutants depend on salon characteristics such as ventilation and the number of customers but also on used products that are often country- or client-specific. For exposure to formaldehyde, ammonia, and TVOC exceeding OELs or guidance values for indoor air was observed. Therefore, occupational exposure should be taken into account by safety regulations for hair care products.

OBJECTIVE: To review the literature on respiratory effects of persulfate salts (PS) or hair bleaches in hairdressers and animal models exploring mechanisms behind PS-induced asthma. METHODS: A systematic review according to the PRISMA guidelines was performed. Studies published from 2000 to July 2021 that fulfilled predefined eligibility criteria were retrieved. Data were not quantitatively synthesized due to the heterogeneity of study designs, outcomes and methods. RESULTS: Forty-two articles were included. PS are indicated as the main cause of occupational rhinitis and asthma in hairdressers, and one of the leading causes of occupational asthma in some European countries. Bleaching products are indicated as the most important factor for development of respiratory symptoms, lung function decline, and leaving the hairdressing profession. Risk estimates from a good quality prospective study showed up to 3.9 times higher risk for wheezing and breathlessness in hairdressers aged ≥ 40 years than in matched controls, and 20 times higher risk in hairdressers to develop respiratory symptoms from exposure to bleaching powder than controls. Pathophysiological mechanisms of the respiratory response to PS are not yet fully elucidated, but may include non-specific and specific immune responses. CONCLUSIONS: Hairdressing is associated with a wide spectrum of respiratory adverse effects, of which bleaching products were indicated as the most hazardous. Preventive measures for reducing inhalatory exposure to PS in hair salons should be re-evaluated, including adopting occupational exposure limits at EU level, and encouraging use of safer bleach formulations.

Objective: Chronic stress has been related to impaired body composition (bone, muscle, adipose tissue), and disturbed autonomic nervous system (ANS), the latter regulated by hypothalamic-pituitary-adrenal (HPA) axis. Our objective was to investigate the relationship between salivary cortisol, body composition and heart rate variability (HRV-highly influenced by ANS), in a young student population. Methods: Body composition and HRV parameters were measured using two portable devices based on multi-frequency bioelectrical impedance and photoplethysmography. Body composition included measurement of bone, lean/muscle and adipose tissues. HRV included time domain and frequency domain indices. Salivary cortisol, immediately after awakening, 60 min post awakening and late night was collected and analyzed by ELISA. Results: Participants included n = 43 healthy university students (39 women, 4 men); 21.1 ± 1.3 years, BMI = 21.8 ± 3.4 kg/m2. Skeletal muscle was reduced in most of the participants, bone mass was at the lower normal range, while the fat tissue parameters were normal with only 7% participants being overweight. Cortisol and HRV parameters of sympathetic predominance (low frequency-LF and low frequency/high frequency ratio-LF/HF) were significantly associated with higher fat tissue parameters (fat mass-FM% and intramuscular adipose tissue-IMAT%) (p <0.001 and p = 0.035, respectively) and with lower skeletal muscle (p = 0.002) and bone mass (p = 0.025). Conclusions: The results point to a role of cortisol and ANS in the control of all three body composition compartments, suggesting that the stress can result in adverse effects on body composition, even in young, apparently healthy individuals.

BACKGROUND: Studies investigating simultaneous influence of personal and work-related factors on skin health during the coronavirus disease 2019 (COVID-19) pandemic are missing. OBJECTIVES: To investigate the associations of skin hazards relevant for nursing apprentices with parameters of skin barrier function. METHODS: A total of 238 nursing apprentices attending the final year of education (median age 19 years) from vocational schools in Zagreb, Croatia, were enrolled in this study. We administered a questionnaire based on the Nordic Occupational Skin Questionnaire to the nursing apprentices, performed clinical examination of skin on the hands, and evaluated transepidermal water loss (TEWL) and stratum corneum (SC) pH on the dorsum of the hand. RESULTS: Around half of nursing apprentices had compromised hand skin barrier function, as indicated by TEWL values >25 g/m2 /h (48%) and SC pH >5.5 (57%). Skin barrier was compromised in around 40% of nursing apprentices without clinically observed skin symptoms. Elevated SC pH was independent of ambient conditions associated with skin symptoms and female sex. CONCLUSIONS: Measurement of SC pH was shown to be less sensitive to field conditions than TEWL, and should be employed more in the field studies. Strengthening of skin health promotion in healthcare workers and apprentices is needed in pandemic conditions.

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.

Hairdressers are at high risk of developing occupational hand eczema. Opinions on the health and safety concerns of nonfood consumer products, such as cosmetics and their ingredients, consider the exposure of a "common consumer," which may not account for occupational exposure of hairdressers. As a result, there is a parlous scenario in which serious safety concerns about occupational exposures are present. The purpose of this review is to compare the frequency of exposure to various types of hair cosmetic products among hairdressers and consumers. Database searches for this review yielded a total of 229 articles; 7 publications were ultimately included. The analysis showed that-dependent on the task-hairdressers were exposed 4 to 78 times more than consumers to a wide spectrum of hair cosmetic products used in their daily working life, ranging from shampoos, conditioners, oxidative and nonoxidative hair colors, to bleaching agents. The highest frequency was found for coloring hair with oxidative hair color. Consumer use frequency does not appear to be appropriate for representing hairdresser exposure. The current standards do not effectively address the occupational risks associated with hairdressers' use of cosmetics. The findings of this study should cause current risk-assessment procedures to be reconsidered.

Current cosmetic regulations primarily focus on protecting consumers, not the professional user who is subjected to a partly different, and certainly more intense exposure to hazardous substances. Against this background, this systematic review aims to compile and appraise evidence regarding skin toxicity of 2-hydroxyethyl methacrylate (HEMA; CAS no. 212-782-2) and ethyl cyanoacrylate (ECA; CAS no. 7085-85-0) contained in cosmetic glues used among hairdressers and beauticians who perform nail treatments and eyelash extension as well as hair extension applications. This systematic review followed the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) 2020 recommendations for reporting systematic reviews and meta-analysis. In total, six publications from six countries were eligible for this systematic review. A meta-analysis revealed that hairdressers and beauticians have a ninefold increased risk of developing contact allergy to HEMA compared with controls who are not hairdressers and beauticians. Results for ECA are lacking. The results of this systematic review clearly show that-regarding contact allergy to acrylates-it is not appropriate to apply risk assessment for consumers to hairdressers and beauticians who occupationally handle cosmetic glues. The regulations in existence do not adequately address occupational risks for hairdressers and beauticians connected with the use of acrylate-containing cosmetic substances and need reconsideration.

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.

INTRODUCTION: Hairdressers constitute a major subgroup in the service sector. They are exposed to various substances hazardous for skin, airways or systemically. Accordingly, skin and other occupational diseases are common. The present systematic review will compile and appraise evidence regarding skin, systemic and airways toxicity of an indicative set of specific, important product ingredients. Additionally, evidence concerning hand eczema morbidity among hairdressers will be reviewed. METHODS AND ANALYSIS: Systematic searches will be performed in two electronic literature databases (Medline, Web of Science-Core Collection), the Cochrane register and two collections of toxicological dossiers (Scientific Committee on Consumer Safety of the European Commission and the MAK Commission of the German Research Council). Additional literature sources will be retrieved using hand search of reference lists of included studies and snowballing methods. We will include studies with all types of quantitative study designs, including results from in vitro and in vivo experiments, chemical analysis, epidemiological findings and clinical results. We will assess the risk of bias within studies amalgamating an abbreviated version of the Mixed Methods Appraisal Tool, basic Cochrane criteria and US Environmental Protection Agency assessment factors for scientific information. As we expect large heterogeneity in methods and outcomes, we will conduct a narrative synthesis of results instead of a meta-analysis, except where quantitative pooling is feasible. ETHICS AND DISSEMINATION: Ethical approval and patient consent are not required as this is a systematic review based on published studies. The results of this study will be published in international peer-reviewed journals. PROSPERO REGISTRATION NUMBER: CRD42021238118.

BACKGROUND: Hairdresser apprentices (HAs) are at high risk of developing occupational contact dermatitis. OBJECTIVES: To assess skin characteristics of HAs, using genotyping, clinically observed and self-reported skin symptoms, and skin bioengineering methods at the beginning of apprenticeship. METHODS: During the screening phase of a prospective cohort study, we recruited 352 HAs in 24 Croatian towns. The protocol included the following: questionnaires with self-reported skin and atopy symptoms evaluation, Osnabrueck Hand Eczema Severity Index (OHSI) for clinical skin assessment, genotyping FLG (filaggrin) gene mutations, skin pH, and transepidermal water loss (TEWL) measurements. RESULTS: Self-reported skin symptoms were reported by 12%, history of dry hands by 29%, and history of atopy by 46% of HAs. Skin changes were found at the clinical examination in 18% of the HA. The OHSI score was positively correlated with hand TEWL and hand skin pH in multiple regression linear models. An FLG gene mutation was found in 1 apprentice. CONCLUSIONS: Significant prevalence of clinically observed skin signs on the hands was observed in HAs at the beginning of training. The OHSI score was found to be an independent predictor of higher hand TEWL and skin pH values. The need to ameliorate preventive examinations before the enrolment to hairdressing schools was indicated.

The aim of the study was to assess the effectiveness of the specific design of a poisoning prevention intervention. This controlled before-after study followed Solomon design for educational interventions using two groups (the educational intervention group and the control group). Participants comprised parents of children attending kindergartens under the jurisdiction of the City of Zagreb and in the vicinity of Zagreb. The intervention group (N = 336) underwent an educational intervention during parents' meetings comprising oral presentation by the Croatian Poison Control Centre (CPCC) and distribution of gift packages containing child-proof locks, flyers, and stickers with the CPCC contact number. After the intervention they more frequently started keeping the CPCC's number by their telephone or in the list of important numbers than parents in the control group, and this association remained significant when tested by generalized estimating equations for binary outcomes, after the adjustment for parents' characteristics (age, gender and educational level), and clustered by kindergartens (p < 0.001). This means parents acknowledged the CPCC as an adequate and accessible way for initial management of poisoning incidents.
