RESUMO
BACKGROUND: Due to limited availability of commercial test preparations, patch testing patient's own material (POM) is of great importance to diagnose occupational allergic contact dermatitis. OBJECTIVES: To assess the quality of performance and documentation of patch testing with POM in patients with suspected occupational skin diseases (OSD) in Germany. METHODS: Retrospective-prospective analysis of protocols of patch tests with POM was conducted between 2013 and 2021 in patients with suspected OSD and submitted to statutory accident insurance institutions. Assessments were done by predefined criteria. RESULTS: Three thousand and four patch tests with POM from 460 patients were included. A full description of the POM was provided in 73.3% of all tests. The test concentration, test vehicle and pH value were documented in 74.3%, 70.5% and 42.2% of tests, for which the respective parameters were considered relevant. One hundred and sixty-one positive reactions to POM were documented. In 72%, sufficient patch testing with commercial test substances was conducted to investigate the positive reaction. In 30.4%, consecutive patch testing of all ingredients of the POM was done. CONCLUSIONS: The results not only show considerable shortcomings mainly in documentation but also to some extent performance of patch tests with POM in patients with suspected OSD in Germany.

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.

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.

BACKGROUND: Relevant nickel and cobalt release from hairdressing tools has recently been evidenced. Comparable data are not available for tools used in beauty salons. OBJECTIVES: Screening of beauty tools for nickel and cobalt release. METHODS/MATERIALS: Three hundred eight beauty tools were tested in seven beauty salons located in two North-German states. A nickel spot test and a cobalt spot test were used to test the tools for nickel release and cobalt release, respectively. RESULTS: One hundred forty-three of 308 beauty tools overall (46.4%; 95% confidence interval [CI]: 40.8%-52.2%) released nickel and 18 of 308 beauty tools overall (5.8%; 95%CI: 3.5%-9.1%) released cobalt. Nickel release was found in 22 of 99 metal tools (22.2%; 95%CI: 14.5%-31.7%) and 121 of 209 tools with metallic parts (57.9%; 95%CI: 50.9%-64.7%); cobalt release was detected in 3 of 99 metal tools (3.0%; 95%CI: 0.63%-8.6%) and 15 of 209 tools with metallic parts (7.2%; 95%CI: 4.1%-11.6%). CONCLUSIONS: Nickel and cobalt are emitted at allergologically relevant levels by a wide range of beauty tools (i.e., metal tools and tools with metallic parts) utilized in the German cosmetics trade. Beauty tools should thus be considered occupational sources of nickel and cobalt exposure.

BACKGROUND: Patients taking part in a tertiary individual prevention program (TIP) for work-related skin diseases frequently have chronic hand eczema (HE) for which alitretinoin is a treatment option. OBJECTIVE: To investigate treatment with alitretinoin before and during the TIP and related factors. METHODS: Data of 1614 patients taking part in the TIP between January 2015 and December 2019 were analyzed retrospectively. RESULTS: Three hundred forty-eight patients (21.6%) reported treatment with alitretinoin prior to the TIP showing an increase over time, particularly in men. In 45 patients (2.8%), alitretinoin treatment was initiated during the TIP. Treatment with alitretinoin was significantly less common among female than male patients, both prior to (P < .001) and during the TIP (P = .015). Female patients who had received alitretinoin in the past were significantly older than the other female patients (P < .001). Among patients treated with alitretinoin prior to the TIP, women had a significantly higher disease severity at admission than men (P = .007). CONCLUSIONS: About twenty percent of patients reported treatment with alitretinoin prior to the TIP. The data indicate that treatment of female TIP patients with alitretinoin is less frequent than among male patients and depends on age and disease severity.

BACKGROUND: In Germany, a multistep approach has been established to prevent work-related skin diseases (WRSDs). OBJECTIVES: To evaluate the effect of a secondary individual prevention program (SIP) in metalworkers with WRSD and to compare their characteristics with those of participants of a tertiary individual prevention program (TIP). PATIENTS AND METHODS: In a prospective cohort study, metalworkers with WRSD of the hands participating either in the SIP (n = 114) or in the TIP (n = 83) were recruited. At baseline and at the respective follow-up 8-12 weeks after the SIP or at dismissal from the TIP (3-4 weeks later), questionnaires were completed and the severity of WRSD was assessed. Saliva samples were collected for assessment of filaggrin (FLG) mutations and an explorative genome-wide association study (GWAS). RESULTS: Ninety-three SIP patients (81.6%) attended the follow-up. Disease severity was significantly reduced, and knowledge and protective behavior were significantly improved compared to baseline. Significant differences between SIP and TIP patients were found regarding duration and severity of symptoms, work absenteeism, tobacco smoking, and presence of atopic dermatitis, but not regarding FLG mutations and by GWAS. CONCLUSIONS: The SIP was effective in metalworkers with WRSDs. Individual factors may influence the course of the disease and the need for the TIP.

PURPOSE: Prevalence of skin cancer is rapidly increasing. There is a need for non-invasive biomarkers to assess efficacy of prevention strategies aiming at reduction of exposure to ultraviolet radiation (UVR). Recently, stratum corneum (SC) biomarkers were applied in various inflammatory skin diseases. Here, we explore their suitability as candidate biomarkers for UVR. MATERIAL AND METHODS: Twelve volunteers were exposed to a UVB-dose of 0.72 SED, three times a week, during three weeks. As candidate biomarkers, cis-isomers of urocanic acid (cUCA) and 25 immunological mediators were measured in the SC. RESULTS: Eight immunological markers significantly changed from baseline. Of them, IL-1RA/IL-1α and a placental growth factor (PIGF) showed gradual changes during UVR-exposure (p < 0.01 for linear trend). cUCA increased sharply already after the first exposure, however, reached a plateau in the second week. CONCLUSIONS: SC represents a promising, non-invasive alternative to skin biopsy in detecting UVR-induced changes. cUCA is the marker of choice for assessment of single UVR-exposure; however, it is less suitable for cumulative UVR-dose. Immunological markers including IL-1RA/IL-1α and PIGF showed gradual changes, and therefore are convenient for monitoring chronic UVR-exposure. These candidate biomarkers might facilitate assessment of the efficacy of preventive measures in the workplace and general population.

BACKGROUND: Metal work apprentices (MWAs) frequently develop work-related hand eczema (HE). OBJECTIVES: To evaluate the effect of health education on incidence of work-related HE in MWAs and to assess confounding factors. MATERIALS/METHODS: In a prospective controlled intervention study, 131 MWAs received educational training on prevention of HE, whereas 172 MWAs and 118 office work apprentices served as controls. At baseline and during three yearly follow-ups, questionnaires were completed and hands were examined. Saliva samples were collected for assessment of filaggrin (FLG) null mutations and an explorative genome-wide association study (GWAS), and levels of various cytokines were assessed from stratum corneum samples. RESULTS: The 2-year and 3-year incidence of HE in the metalwork control group was 20.9% and 32.6%, respectively, which was significantly higher than in the intervention group (odds ratio [OR] 2.63, 95% confidence interval [CI] 1.31 to 5.28, P < .01 and OR 3.47, 95% CI 1.88 to 6.40, P < .0001). The knowledge score was higher in unaffected MWAs (P < .05). Other factors significantly associated with developing HE in MWAs were smoking cigarettes (P < .01) and FLG mutations (P < .001). No significant associations were found regarding epidermal cytokine levels and GWAS. CONCLUSIONS: Health education is effective in primary prevention of HE in MWAs. Individual factors should be considered in targeted counseling.

BACKGROUND: Occupational skin diseases (OSDs) are the most common work-related diseases in Germany and responsible for a large individual and financial burden. Therefore, a tertiary individual prevention program (TIP) is offered to patients with severe OSD who are at increased risk of abandoning their profession. OBJECTIVES: To define cost of illness (COI) of OSD in Germany and to economically evaluate the TIP from a societal perspective. METHODS: In this study, data on patients taking part in the TIP (September 2005 to December 2009) were collected. Sociodemographic and medical data, costs, disease severity (Osnabrueck Hand Eczema Severity Index), and quality of life (QoL; Dermatology Life Quality Index) were assessed. COI and cost-effectiveness analyses were performed with a simulated control group. RESULTS: In the analysis, 1041 patients were included. Intervention costs per person were 15 009 with decreasing COI over time. The incremental cost-effectiveness ratio revealed expenses per patient of 8942 for a reduction in severity level and 9093 for an improvement in QoL in the base case. Considering costs for retraining, the break-even point is reached if the TIP prevents retraining in approximately 64% of participants. CONCLUSIONS: The decreased COI in this long-term evaluation indicates that the TIP is cost-effective in patients with severe OSD.

BACKGROUND: Nickel is one of the most common contact allergens. Despite EU regulations concerning the maximum permissible release of nickel from metal objects, nickel release at inappropriately high levels from metal objects has been detected in various studies. OBJECTIVES: To screen current nickel release from metal tools in the German hairdressing trade. METHODS: Two hundred and twenty-nine metal tools from the German hairdressing trade were tested with the dimethylglyoxime (DMG) test for nickel release. Additionally, an employee survey was conducted to collect data about the metal tools. RESULTS: The DMG test showed that 21 of 229 metal tools (9.2%) released nickel. Nickel release was detected in 8 of 45 hair clips (17.8%), 2 of 27 tail combs (7.4%), and 11 of 17 tweezers (64.7%). CONCLUSION: It must be assumed that hairdressers in Germany have prolonged skin contact with nickel-releasing metal tools. This should prompt further testing for nickel release from metal tools, and the development of regulations to eliminate nickel-releasing metal tools in the (German) hairdressing trade.

BACKGROUND: The World Health Organization (WHO) and the International Labour Organization (ILO) are developing a joint methodology for estimating the national and global work-related burden of disease and injury (WHO/ILO joint methodology), with contributions from a large network of experts. In this paper, we present the protocol for two systematic reviews of parameters for estimating the number of deaths and disability-adjusted life years from melanoma and non-melanoma skin cancer (or keratinocyte carcinoma) from occupational exposure to solar ultraviolet radiation, to inform the development of the WHO/ILO joint methodology. OBJECTIVES: We aim to systematically review studies on occupational exposure to solar ultraviolet radiation (Systematic Review 1) and systematically review and meta-analyse estimates of the effect of occupational exposure to solar ultraviolet radiation on melanoma and non-melanoma skin cancer (Systematic Review 2), applying the Navigation Guide systematic review methodology as an organizing framework and conducting both systematic reviews in tandem and in a harmonized way. DATA SOURCES: Separately for Systematic Reviews 1 and 2, we will search electronic academic databases for potentially relevant records from published and unpublished studies, including Ovid Medline, PubMed, EMBASE, and Web of Science. We will also search electronic grey literature databases, Internet search engines and organizational websites; hand-search reference list of previous systematic reviews and included study records and consult additional experts. STUDY ELIGIBILITY AND CRITERIA: We will include working-age (≥15â¯years) workers in the formal and informal economy in any WHO and/or ILO Member State, but exclude children (<15â¯years) and unpaid domestic workers. For Systematic Review 1, we will include quantitative studies on the prevalence of relevant levels of occupational exposure to solar ultraviolet radiation (i.e. <0.33â¯SED/d and ≥0.33â¯SED/d) and of the total working time spent outdoors, stratified by country, sex, age and industrial sector or occupation, in the years 1960 to 2018. For Systematic Review 2, we will include randomized controlled trials, cohort studies, case-control studies and other non-randomized intervention studies with an estimate of the effect of any occupational exposure to solar ultraviolet radiation (i.e., ≥0.33â¯SED/d) on the prevalence of, incidence of or mortality due to melanoma and non-melanoma skin cancer, compared with the theoretical minimum risk exposure level (i.e. <0.33â¯SED/d). STUDY APPRAISAL AND SYNTHESIS METHODS: At least two review authors will independently screen titles and abstracts against the eligibility criteria at a first stage and full texts of potentially eligible records at a second stage, followed by extraction of data from qualifying studies. At least two review authors will assess the risk of bias and the quality of evidence, using the most suited tools currently available. For Systematic Review 2, if feasible, we will combine relative risks using meta-analysis. We will report results using the guidelines for accurate and transparent health estimates reporting (GATHER) for Systematic Review 1 and the preferred reporting items for systematic reviews and meta-analyses guidelines (PRISMA) for Systematic Review 2. PROSPERO REGISTRATION NUMBER: CRD42018094817.

BACKGROUND: Allergic contact dermatitis (ACD) is one of the most common occupational skin diseases (OSDs). Its prevalence and the causative allergens differ between occupations. OBJECTIVES: To evaluate the prevalence of ACD and the pattern of patch test results of patients taking part in a tertiary individual prevention programme (TIP) for OSD in Germany. PATIENTS AND METHODS: In a retrospective cohort study, the data of 3411 TIP patients patch tested between 2007 and 2016 were analysed. RESULTS: In 2687 (78.8%) patients, work-related skin disease was diagnosed, mostly hand dermatitis. The highest proportion of face dermatitis was seen in painters (8.1%). ACD was most common in painters (56.8%), hairdressers (45.8%), construction workers (31.5%), gardeners/florists (26.7%), and metalworkers (26.5%). On average, hairdressers had the youngest age (31.4 ± 12.6 years, P < 0.0001) and the shortest time in the profession prior to the TIP (mean 13.7 years). The pattern of patch test reactivity showed occupation-specific differences related to work exposures. CONCLUSIONS: Identification of occupational groups at risk for ACD and relevant allergens may help in the development and implementation of targeted prevention strategies. Our data suggest that there should be a particular focus on hairdressers and painters.

BACKGROUND: Occupational skin diseases (OSDs) are frequent in professions with exposure to skin hazards. Thus, a health educational intervention for apprentices of high-risk professions was conducted. It was the aim of this study to gain insight into possible effects of this intervention. METHODS: A one-time skin protection seminar was conducted in 140 apprentices of health-related and non-health-related professions [trained cohort (TC)]. In addition, 134 apprentices of the same occupations were monitored [untrained cohort (UTC)]. The OSD-specific knowledge and the skin condition of the hands were assessed at baseline (T0), after the seminar (T1), and after 6 (T2) and 12 months (T3). RESULTS: The OSD-specific knowledge increased in all cohorts from T0 to T3, but we found a significantly higher knowledge in the TC at T2 (p < 0.001, t = 3.6, df = 196, 95% confidence interval = 0.9, 3.3) and T3 (p < 0.001, t = 3.8, df = 196, 95% confidence interval = 1.0, 3.2) compared to the UTC. Our results indicated a better skin condition of the hands in the TC of the health-related professions but not in the non-health-related professions. CONCLUSION: The study indicates that an educational intervention may positively influence the disease-specific knowledge and the prevalence of OSD in apprentices. However, definite conclusions cannot be drawn because of the heterogeneous study cohorts and the study design. Future research should aim at tailoring primary prevention to specific target groups, e.g., in view of the duration and frequency of skin protection education, different professions, and gender-specific prevention approaches.
RESUMO
BACKGROUND: A tertiary individual prevention programme (TIP) is offered to patients with severe occupational skin disease (OSD) in Germany. Previously, it was shown that the burden of OSDs is considerably reduced in patients up to 1 year after the TIP. OBJECTIVES: To evaluate the long-term effects of the TIP. PATIENTS AND METHODS: In a prospective multicentre cohort study, the clinical and patient-reported outcome data 3 years after the TIP were evaluated. RESULTS: Of the 1788 patients initially included in the study, 1410 were available for the 3-year follow-up analysis. The severity of OSD, the use of topical corticosteroids and days of absence from work were significantly reduced 3 years after the TIP, and the quality of life and skin protective behaviour were significantly improved. Of the patients, 96.9% were able to resume work. One thousand one hundred and sixty-six patients (82.7%) were still working 3 years after the TIP, 874 of them (75.0%) in the same occupational field. Hairdressers had the lowest rate of remaining in their original profession (41.3%). CONCLUSIONS: The follow-up during 3 years of this unique cohort of patients with OSDs shows that the TIP is associated with sustained improvements in terms of disease severity, ability to work, quality of life, and prognosis.

BACKGROUND/PURPOSE: Urocanic acid (UCA) absorbs ultraviolet (UV)B radiation in the epidermis which may interfere with phototherapy. Therefore, the influence of individual levels of UCA on immune reactivity and vitamin D synthesis induced by narrowband UVB radiation was assessed. METHODS: Twenty-eight subjects with irritant contact dermatitis of the hands were irradiated with suberythemal doses of narrowband UVB radiation on their unaffected lower forearms on three consecutive days. Stratum corneum tape strips and epidermal interstitial fluid (ISF) as well as blood samples were analyzed. RESULTS: Narrowband UVB irradiation led to the conversion of trans-UCA into its cis-isomer in the epidermis. The observed increase in 25-hydroxyvitamin D serum concentrations was inversely correlated with the baseline levels of trans-UCA. Furthermore, UVB irradiation induced significant changes in the levels of CXCL10/IP-10, CCL2/MCP-1, CCL4/MIP-1ß, and the IL-1RA/IL-1α ratio. The levels of IL-1α and CXCL9/MIG showed a trend toward increase. The changes in the levels of inflammatory and immunomodulatory mediators did not depend on baseline levels of trans-UCA. CONCLUSION: The results suggest that epidermal levels of trans-UCA affect vitamin D synthesis, but not cutaneous immune reactivity upon repeated exposure to suberythemal doses of narrowband UVB radiation. However, this requires further exploration.

BACKGROUND: Foot eczema often occurs in combination with hand eczema. However, in contrast to the situation with hand eczema, knowledge about foot eczema is scarce, especially in occupational settings. OBJECTIVE: To evaluate the prevalence of foot eczema and associated factors in patients with hand eczema taking part in a tertiary individual prevention programme for occupational skin diseases. PATIENTS/MATERIALS/METHODS: In a retrospective cohort study, the medical records of 843 patients taking part in the tertiary individual prevention programme were evaluated. RESULTS: Seven hundred and twenty-three patients (85.8%) suffered from hand eczema. Among these, 201 patients (27.8%) had concomitant foot eczema, mainly atopic foot eczema (60.4%). An occupational irritant component was possible in 38 patients with foot eczema (18.9%). In the majority of patients, the same morphological features were found on the hands and feet (71.1%). The presence of foot eczema was significantly associated with male sex [odds ratio (OR) 1.78, 95% confidence interval (CI) 1.29-2.49], atopic hand eczema (OR 1.60, 95%CI: 1.15-2.22), hyperhidrosis (OR 1.73, 95%CI: 1.33-2.43), and the wearing of safety shoes/boots at work (OR 2.04, 95%CI: 1.46-2.87). Tobacco smoking was associated with foot eczema (OR 1.79, 95%CI: 1.25-2.57), in particular with the vesicular subtype. CONCLUSIONS: Foot eczema is common in patients with hand eczema, and is related to both occupational and non-occupational factors.

Chronic hand eczema places a heavy burden on patients, often affecting their ability to work. This paper compares the cost-of-illness and treatment approaches for patients with refractory chronic hand eczema, in relation to whether the disease was occupational or unrelated to work factors. Data from 2 surveys, comprising 310 patients with chronic hand eczema insured by German statutory health insurance (SHI) (including work-impaired patients, work-unaffected patients and non-working patients) and known work-related chronic hand eczema insured by occupational health insurance (OHI). Annual healthcare costs of managing work-impaired patients (SHI) and patients with work-related chronic hand eczema (OHI) were 3,164 and 3,309, respectively, approximately double the costs of managing non-working and work-unaffected (SHI) patients. This analysis shows that the costs associated with chronic hand eczema are affected by the correlation of chronic hand eczema with work, with costs being higher for occupational patients with chronic hand eczema.

BACKGROUND: Loss-of-function mutations in the filaggrin gene (FLG) have been reported to be associated with specific phenotypic characteristics such as hyperlinearity and keratosis pilaris. OBJECTIVES: To study phenotypic features in patients with occupational irritant contact eczema of the hands in relation to FLG loss-of-function mutations. MATERIALS AND METHODS: In a prospective cohort study, genotype was determined for 459 study subjects for four FLG null alleles, and investigated for selected history, clinical and laboratory features. RESULTS: Overall, 68 patients showed a mutation in the FLG alleles R501X, R2447X, S3247X, and/or 2282del4. Flexural eczema, xerosis cutis, pityriasis alba, dirty neck, pulpitis sicca, hyperlinear palms, keratosis pilaris and family history of eczema were positively associated with FLG mutations (p < 0.05). Although we observed a statistically significant correlation with higher serum IgE in FLG mutation carriers, allergic rhinoconjunctivitis and allergic asthma were not over-represented in this group. CONCLUSION: This study shows further genotype-phenotype correlations in patients with occupational irritant contact eczema and FLG mutation carrier status. These features may help to identify those with FLG mutations on a specific phenotype basis.

BACKGROUND: Occupational skin disease (OSD) is common, and imposes a considerable personal and public burden. To tackle OSD, the German stepwise procedure of handling OSD was set up. It contains an interdisciplinary, integrated inpatient rehabilitation measure [tertiary individual prevention (TIP)] [dermatological treatment and diagnostic procedures, and patient education (health and psychological)]. The primary aims of the TIP are reduction of the severity of OSD, reduction in the use of corticosteroids, facilitation of return to work, decreased absence from work, and enhanced quality of life (QoL). It was positively evaluated for a period of 4 weeks after return to work. OBJECTIVES: To investigate whether the observed short-term effects remain significant and meaningful over a period of 12 months after discharge from the TIP. METHODS: A prospective design was used to compare clinical and patient-reported outcome data between admission to a 3-week inpatient TIP and 12 months after discharge (12-month follow-up). RESULTS: Of 1788 individuals admitted to the TIP, data from 1617 individuals were available for analysis. We observed a significant reduction in the severity of OSD, the use of topical corticosteroids, and days of absence from work because of OSD. QoL was significantly improved, and 87.4% were able to return to work and remain in the workforce. CONCLUSIONS: A randomized controlled trial would have been desirable, but was not possible, for legal and other reasons. However, the long-term 12-month follow-up shows that the TIP is associated with sustained improvements in terms of ability to work, QoL, and prognosis, and reductions in days of absence from work because of skin conditions and topical corticosteroid application. These results indicate that the TIP provided a reduction in the personal and public burden of OSD.
