Chronic hand eczema (CHE) is a complex, challenging, and frequently multifactorial skin disease of the hands. It is very common in the general population, especially in certain professions. When hand eczema (HE) persists for longer than 3 months or has a minimum of two relapses per year after initial manifestation with complete clearance, it is considered chronic. In this case, health-related quality of life and the patient's working life are often impaired. CHE can be considered as an umbrella term because it covers different clinical pictures and etiologies. To date, there is no definite and unique HE classification. Treatment starts with identifying the individual HE etiology paralleled by symptomatic therapy (local and/or systemic and/or ultraviolet phototherapy). Sustainable management of HE requires the identification and avoidance of its triggering factors, from the professional and private environment. This includes ruling out allergic contact dermatitis if any HE persists for more than 3 months despite adequate therapy. Randomized controlled trials investigating the efficacy in HE are lacking for several treatment modalities. Patient education measures of skin protection and prevention complete the multimodal treatment., (© 2024. The Author(s).)

Sustainability is becoming increasingly important in healthcare and has moved into focus at various levels. This article aims to provide an overview of guiding principles, concepts, and target systems of sustainability and to transfer these to occupational dermatology. Current and future starting points are outlined for various levels, e.g., politics, research, industry, and patient care, in order to link sustainability and occupational dermatology in a structured and systematic way and to transform the structures of patient care in occupational dermatology care towards sustainability. Using the specific example of protective gloves, which is a pivotal personal protective measure to prevent work-related hand eczema, starting points, potentials, and challenges are analyzed and specific possibilities and perspectives for more ecologically sustainable action are presented., (© 2024.

Background: Occupational contact dermatitis often results in work disruption. Return-to-work (RTW) is an important outcome., Objective: The objective of this study was to determine RTW outcomes and factors associated with such outcomes using a multidisciplinary clinic model., Methods: Chart abstraction was performed for 194 workers who received RTW assistance over a 6-year period. Elements abstracted included demographic and diagnostic information and information about the RTW program including principles, program components, barriers, and facilitators., Results: Of the 902 workers seen for dermatologic assessment, 194 received RTW assistance. At initial assessment, 37% were not working because of their skin disease, and at follow-up, 7% were not working because of their skin disease. The RTW plan components included a graduated or trial of RTW, specific recommendations for avoiding exposure, personal protective equipment, skin management, and ongoing skin monitoring. Principles associated with successful RTW included good communication and the availability of modified work and a worker adherence to the plan. Barriers included lack of modified work, unresponsive employers, and ongoing skin problems., Conclusions: Specific approaches are important to identify if RTW is to be successful for workers with occupational contact dermatitis., (© 2021 John Wiley & Sons A/S.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become a significant health problem globally. The virus has spread widely and become a global pandemic. The pathophysiology for SARS-CoV-2 has not been explained clearly. It has been associated with several multiorgan symptoms, among which its dermatological manifestations are of great interest. Primarily, there has been no report of skin features among COVID-19 patients. Nevertheless, recently there have been several reports regarding COVID-19 patients who presented with cutaneous manifestations. In the current review, we focus on the various cutaneous manifestations of COVID-19 infection., (© 2021 Wiley Periodicals LLC.)

During the COVID-19 pandemic, prolonged usage of personal protective equipment (PPE) and frequent handwashing has exacerbated or caused skin diseases, particularly amongst frontline workers. Skin conditions, such as atopic dermatitis, irritant contact dermatitis, and hand eczema, affect patients’ quality of life and their ability to work. These conditions can be managed by frequent moisturization and washing with gentle cleansers. In this review, we discuss the properties of effective moisturizers and cleansers for patients with skin diseases related to enhanced infection control procedures., Competing Interests: Sara Mirali has no conflicts of interest to declare.

Background: Prolonged wear of facial protective equipment can lead to occupational dermatoses., Objective: To identify important causes of occupational dermatoses from facial protective equipment., Methods: A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed using PubMed and Embase databases. Articles were included if they reported occupational dermatoses caused by surgical/procedure masks or N95 respirators, or both., Results: We identified 344 articles, and 16 were suitable for inclusion in this review. Selected articles focused on facial occupational dermatoses in health care workers. Allergic contact dermatitis to the elastic straps, glue, and formaldehyde released from the mask fabric was reported. Irritant contact dermatitis was common on the cheeks and nasal bridge due to pressure and friction. Irritant dermatitis was associated with personal history of atopic dermatitis and prolonged mask wear (>6 hours). Acneiform eruption was reported due to prolonged wear and occlusion. Contact urticaria was rare., Limitations: Only publications listed in PubMed or Embase were included. Most publications were case reports and retrospective studies., Conclusion: This systematic review from members of the American Contact Dermatitis Society highlights cases of occupational dermatitis to facial protective equipment, including potential offending allergens. This work may help in the diagnosis and treatment of health care workers with facial occupational dermatitis., (Copyright © 2020. Published by Elsevier Inc.)

Background: There are no reported cases of 2,4-dichloro-5-methylpyrimidine (DCP)-induced irritant contact dermatitis (ICD)., Objective: The aim of the study was to summarize the clinical features, treatment, and protective measures for DCP-induced ICD., Methods: We retrospectively reviewed the clinical data from 64 patients with DCP-induced ICD and the protective measures in a DCP manufacturing factory., Results: Disease onset occurred 1 to 10 minutes after DCP single exposure in all 64 patients. The contact site developed edematous erythematous skin lesions with clear boundaries. Other symptoms included a burning sensation (n = 48), pruritus (n = 16), headache (n = 4), nausea/vomiting (n = 3), and syncope (n = 1). Ten patients developed pruritic rash over the whole body 1 to 4 days after contacting DCP. Histopathologic examination of the lesions was performed in 8 patients; all 8 showed manifestations of ICD. A patch test with 1% DCP ethanol solution was performed in 7 patients. One patient withdrew because of pruritus and massive erythema over the whole body. Four patients had a strong reaction, and 2 patients had a very strong reaction. All patients were cured. Positive-pressure inflatable protective clothing protected workers from the outside environment to prevent DCP-induced ICD., Conclusions: 2,4-Dichloro-5-methylpyrimidine exposure induces acute ICD and a delayed allergic reaction in some patients (15.6%). Positive-pressure inflatable protective clothing prevents DCP-induced ICD., Competing Interests: The authors have no funding or conflicts of interest to declare., (Copyright © 2021 The Author(s).

The aim of this study was to evaluate the skin problems and dermatological life quality of the health care workers (HCWs) due to personal protection equipment (PPE) use, who are at high risk for COVID-19 infection. A questionnaire about HCWs' PPE use, their skin symptoms, and prevention, management methods and Dermatology Life Quality Index (DLQI) was fulfilled. The median age of 440 participants was 33.5 (21.0-65.0) years old. Skin problems were found to be 90.2%, the most common were dryness, itching, cracking, burning, flaking, peeling and lichenification. The presence of skin problems (P < .001) was higher in those who did not use moisturizers. Of all, 22.3% (n = 98) stated that the use of PPE increased the severity of their previously diagnosed skin diseases and allergies (P < .01). Only 28.0% (n = 123) stated that they know the skin symptoms that may develop by using PPE. The proper hand washing rate was higher as education level increased (P < .001). Skin problems were higher in those using mask with metal nose bridge (P: .02 and P: .003, respectively). As the mask using period prolonged, acne was more common (P: .02). DLQI was significantly affected in women (P = .003), and with increased skin problems related to PPE (P < .001). It is important to organize trainings on prevention and management of possible skin symptoms due to PPE use according to guidelines., (© 2020 Wiley Periodicals LLC.)

Background: Isothiazolinones are preservatives which are present in cosmetics, household chemicals and many other industrial products. Initially, a mixture of methylchloroisothiazolinone and methylisothiazolinone (MCI/MI - Kathon CG) was used, and then, from the beginning of the 21st century, only methylisothiazolinone. Due to a significant increase in the number of contact dermatitis caused by allergy to this compound, it was withdrawn from leave-on cosmetics, and its concentration in rinse-off cosmetics was reduced. The aim of the study was to analyze the incidence of contact allergy to isothiazolinones among patients in the Nofer Institute of Occupational Medicine, Łódź, the intensification of patch test results and hypersensitivity depending on the occupation, and to assess the contribution of immediate allergy to the occurrence of that hypersensitivity., Material and Methods: In a group of 1137 patients (832 females and 305 males) with suspected contact dermatitis, diagnosed in 2014-2018, patch tests series including methylchloroisothiazolinone/methylisothiazolinone (0.01%) and methylisothiazolinone (0.2%), produced by Chemotechnique Diagnostics, Sweden, were performed. In a group of 29 individuals with contact allergy to isothiazolinones, prick tests with methylisothiazolinone (0.001%, 0.01%, 0.1%, 1%) (Sigma-Aldrich, Germany) were conducted., Results: Of the 1137 subjects, 95 (8.3%) were allergic to isothiazolinones, slightly more often females - 71 (8.5%) than males - 24 (7.9%). In total, 150 positive patch tests with isothiazolinones (13.2%) were obtained. The number of positive results with methylisothiazolinone alone (7.8%) was higher than the number with methylisothiazolinone from Kathon CG (5.4%). Among the subjects sensitized to methylisothiazolinone alone strongly positive patch tests (+++) concerned 60.7%. In the female group, office workers (42.3%) and medical staff (18.3%) predominated, and in the male group - locksmiths, turners, mechanics and similar ones (45.8%), and construction workers (25.0%). Prick tests with methylisothiazolinone were negative, and they became positive after 3-5 h., Conclusions: Isothiazolinones, particularly methylisothiazolinone, are significant causal factors of contact allergy, including that of occupational origin. They have strongly allergenic properties, and in patch tests they often give very severe inflammatory reactions. The issue of the role of immediate allergy in the pathogenesis of isothiazolinones sensitization requires further research.

Coronavirus disease 2019 (COVID-19) pandemic continues to spread globally at a staggering speed. At present, there is no effective treatment or vaccine for COVID-19. Hand disinfection is a cost-effective way to prevent its transmission. According to the Centres for Disease Control and Prevention (CDC) guidelines, we should wash our hands with soap and water for at least 20 seconds. If soap and water are not readily available, alcohol-based hand rubs (ABHRs) with at least 60% alcohol are the alternative. With diligent hand disinfection reinforced during COVID-19, there is an increased prevalence of contact dermatitis. This commentary highlights the fact that contact dermatitis is a readily treatable condition and should not cause any deviation of proper hand hygiene. In irritant contact dermatitis (ICD), the management strategies are selection of less irritating hand hygiene products, frequent use of moisturisers to rebuild the skin barrier, and education on proper hand hygiene practices. In allergic contact dermatitis (ACD), the identification and avoidance of the contact allergen is the key to treatment. However, ACD is less common and only accounts for 20% of the cases. The identified allergens in hand cleansers are predominantly preservative excipients and ACD attributable to ABHR are very uncommon. Alcohol-free hand rubs are widely available on the market but it is not a recommended alternative to ABHRs by the CDC.

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., (© 2020 The Authors.

Background: Concerns have been raised that a chronic course of hand eczema (HE) could be fostered by a lack of efficient treatment at an early stage., Objectives: First, to assess the prevalence of systemic treatment in patients with chronic occupational HE (OHE) and relate this to demographic data, HE severity, and atopic dermatitis (AD). Second, to explore the use of complementary and alternative medicine (CAM) in the same population., Methods: Baseline data were obtained from a registry-based study including patients with recognized OHE in a 2-year period in Denmark, comprising a total of 2703 workers. A follow-up questionnaire after 4 to 5 years included questions on disease severity and treatments., Results: A total of 1565 participants responded to the questionnaire, and of these 1203 had ongoing HE at follow-up and were included in the study. In total, 10.0% had received systemic therapy, whereas this share was 13.3% in those with self-reported moderate-to-severe HE. Age >35 years, previous or current AD, and severe eczema were factors related to use of systemic treatment. Use of CAM was reported by 6.2% of the study population., Conclusions: We suggest that chronicity of HE may be perpetuated by the lack of efficient treatment., (© 2020 John Wiley & Sons A/S.

Background: Variables traditionally reported to influence the prognosis of occupational hand eczema (OHE) are atopic dermatitis (AD) and contact sensitization. However, recent studies indicate that lifestyle factors may be of major importance., Objectives: To identify factors influencing the prognosis in a cohort of patients with recognized OHE., Methods: In this register-based cohort study, individuals with hand eczema recognized as occupational disease in the period January 2010-December 2011 were identified using files from Labor Market Insurance Denmark and included in the study. At baseline, information on sex, age, occupation, wet work, AD and contact sensitization was collected. In 2015 participants received a questionnaire with questions about lifestyle factors, current occupation and healing of OHE., Results: In total, 2703 patients received the questionnaire; 1491 responded to the question about healing of OHE and were included in the study. Altogether, 19·3% of patients reported complete healing at follow-up. Current tobacco smoking and a high level of stress were factors inversely associated with healing of hand eczema (P < 0·001 and P = 0·030, respectively), while a high level of exercise was significantly related to healing of eczema (P = 0·011). Change of profession was a favourable prognostic factor, while age, sex, AD, contact sensitization and education did not significantly influence prognosis., Conclusions: Traditionally important risk factors such as AD and contact sensitization had no marked influence on prognosis, while lifestyle factors were of major importance. Our findings indicate that risk factors may vary over time, allowing for new perspectives on prevention. What's already known about this topic? Occupational hand eczema has a relapsing course and a poor overall prognosis. Atopic dermatitis and contact sensitization have previously been reported as risk factors for a poor prognosis. What does this study add? The results indicate that lifestyle factors are of importance for the prognosis of occupational hand eczema. Traditionally reported risk factors such as atopic dermatitis and contact sensitization do not currently influence prognosis., (© 2019 British Association of Dermatologists.)

Purpose of Review: The purpose of this review is to provide an update on occupational contact dermatitis including gaps in knowledge and practice. Occupational contact dermatitis is the most common occupational skin disease., Recent Findings: New sources of exposure for known allergens and new allergens are continually being reported. Through clinical databases and surveillance systems, effects of prevention efforts or introduction of new allergens or new uses of known allergens can be monitored. Though the diagnostic process is clear, there are delays in workers seeking care. As early detection and intervention improves outcomes, screening should be implemented. Gaps in primary prevention in the workplace are identified and should be addressed to reduce the burden of disease. Surveillance systems support the prevention mandate. Understanding limitations of our knowledge and identifying gaps in practice can lead to initiatives to address research and practice needs and improve prevention of occupational dermatoses.

Occupational skin disease is common. It affects workers more often than reported. Contact dermatitis, both irritant and allergic, accounts for the majority of occupational skin diagnoses. Occupational contact dermatitis (OCD) frequently affects the hands and may have a profound impact on an employee's ability to perform a job. Severe OCD can affect a worker's activities of daily living and can even lead to job loss. Numerous irritants have been described in the workplace, from the common (wet work) to the more obscure (warm, dry air). Several contact allergens may be work-related, and the majority of established occupational allergens are also known nonoccupational allergens. Emerging occupational allergens are continually described in the literature. Patch testing is the gold standard for the workup of allergic contact dermatitis. Patch testing in the setting of OCD may require extended or unique allergen trays, as well as a thorough occupational history and collection of workplace Material Safety Data Sheets (MSDS). These MSDS contain valuable information but may not be complete or accurate. Proof of occupational causation can be aided by employing the Mathias criteria. Certain industries and occupations are associated with higher rates of OCD, and as expected, the industries with direct contact with irritants and allergens are highly represented. The differential diagnosis for occupational dermatitis is broad and should be considered when evaluating an employee with suspected OCD. Some other diagnoses to consider include atopic dermatitis, psoriasis, and manifestations of internal disease, as well as an overlap syndrome of more than one diagnosis. OCD treatment should ideally follow the public health hazard controls' stepwise approach. Prevention and early intervention are key to promoting occupational health and preventing OCD. Multidisciplinary teams have been successful in the treatment of OCD, and newly described topical treatments may provide additional modalities for use in the occupational setting.

The first reported cases of allergic contact dermatitis from acrylates in manicure procedures in relation to the application of porcelain nails were published decades ago. The frequency of sensitization has increased due to the introduction of the so-called permanent nail polish containing photo-bonded acrylates, mainly involving the beauticians who apply them, and to a lesser extent, the consumers. The recent commercialized permanent polish kits for domestic use could trigger even higher degrees of sensitization. In this article, the clinical features, diagnostic procedures, treatment and preventive measures are described. Acrylates are present in a wide range of sources including multiple medical materials. Sensitization caused by a merely aesthetic procedure might end up having an eventual important impact in the future consumer's health which is why restrictive policies should be implemented limiting its use to qualified professionals and banning the indiscriminate sale of domestic kits., (Copyright © 2017 AEDV.

Objective: The aim of this review was to identify, appraise and synthesize the best available evidence on the effectiveness of moisturizers, barrier creams, protective gloves, skin protection education and complex interventions (a combination of two or more of the interventions listed here) in preventing occupational irritant hand dermatitis (OIHD) in wet workers, comparing each intervention to an alternative intervention or to usual care (workers' regular skin care regimen)., Introduction: The most significant occupational skin problem potentially encountered in wet work occupations is occupational dermatitis. When the skin comes into contact with hazardous substances at work, this can cause occupational dermatitis. Substances which may cause occupational dermatitis include cleaning products, organic solvents, metalworking fluids, cement, flour, adhesives, other chemicals and even certain plants. Occupational skin disease has adverse effects on quality of life and the long term prognosis for skin health is poor unless workplace exposures are addressed. To date, no systematic review has been undertaken to determine the effectiveness of interventions for the primary prevention of OIHD in wet workers., Inclusion Criteria: The review included any workers from healthcare (e.g. nurses, doctors and allied health professionals) and also people in different wet work occupations (e.g. hairdressers, florists, catering workers, metal workers) at similar risk of OIHD. Studies that assessed the following interventions in the primary prevention of OIHD in wet workers at the workplace and at home (before and after work) were included:Types of studies considered were experimental study designs including randomized controlled trials, non-randomized controlled trials, quasi-experimental, and before and after studies. Primary outcome measures were OIHD incidence, and secondary outcome measures were product evaluation and change of occupation because of OIHD versus staying in the occupation., Methods: Published and unpublished literature in the English language was sought between 2004 and 2017. The databases searched included: COCHRANE CENTRAL, MEDLINE, CINAHL, AMED and Embase. The search for unpublished studies included: Google Scholar, Open DOAR and Robert Gordon University's thesis database, "OPEN AIR"., Results: There were no studies located that met the inclusion requirements of this review., Conclusion: There is currently no evidence available to determine the effectiveness of interventions to prevent OIHD amongst wet workers that met this review's inclusion criteria.

Contact allergies are common cause of eczema in all age groups and are one of the most common causes of occupational disability. Contact dermatitis (CD) can be divided into irritant and allergic contact dermatitis. Distinguishing between irritant and allergic triggers of CD by clinical and histologic examinations can be challenging. The approach to patients with CD should consist of a detailed (work and leisure) history, skin examination, patch tests with allergens based on history, physical examination, education on materials that contain the allergen and adequate therapy and prevention.

Objective: To investigate the efficacy and safety of the recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein (rhTNFR: Fc, etanercept) for the treatment of occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) . Methods: In September 2011 to February 2016, 12 patients with OMLDT were treated with etanercept 25 mg, subcutaneous injection, twice per week, doubling of first dose. The course of treatment was 6 weeks. The drug eruption area and severity index (DASI) score, the proportion of patients achieving a 50%, 75% and 90% reduction in DASI (DASI50, DASI75, DASI90) and the serum level of TNF-α were used to assess the efficacy at different times. Adverse reactions were also recorded and evaluated. The results were statistically analyzed by nonparametric Friedman test and repetitive measurement ANOVA using the software SPSS19.0. Results: After 4 weeks treatment, the DASI score decreased form 56.33±7.02 to 0.50±0.91 ( P <0.01) . The DASI50, DASI75 and DASI90 were all increased to 12 (100%) . The serum level of TNF-α decreased form (43.74±41.62) pg/ml to (3.03±0.47) pg/ml ( P <0.01) . Statistically significant difference was observed from the above indexes. There were no adverse reactions in clinical application. Conclusion: Recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein may be a safe and effective drug in the treatment of OMLDT.

Objective: To investigate the clinical effect and safety of rock salt aerosol therapy in the treatment of occupational allergic contact dermatitis. Methods: A total of 65 patients with acute exacerbation of occupational allergic contact dermatitis who were treated in the Outpatient Service and Inpatient Department of our hospital from March 2013 to December 2015 were enrolled and randomly divided into observation group and control group using a random number table. Both groups were givensymptomatic treatment including desensitization, and the patients in the observation group were given rock salt aerosol therapy for 2 courses in addition to the symptomatic treatment. The changes in symptoms, signs, blood eosinophil count, and IgE were observed. Results: There were significant changes in symptom score at the first and second courses of the treatment ( P <0.05) , and there was an interaction between time of therapy and grouping ( P <0.05) . There was no significant difference in symptom score before treatment between the two groups ( P >0.05) , while there were differences at the first and second courses of the treatment ( P <0.05) . After the second course of treatment, the observation group had a significantly higher overall response rate than the control group ( P <0.05) ; both groups had significant reductions in blood eosinophil count and the observation group had a significantly greater reduction than the control group ( P <0.05) . After two courses of treatment, both groups had significant increases in the number of patients with normal IgE (both P <0.05) , and after the second course of treatment, the observation group had a significantly higher number than the control group ( P <0.05) . Both groups had mild adverse events, which did not affect the treatment. Conclusion: In the treatment of occupational allergic contact dermatitis, rock salt aerosol therapy has a certain effect on the recovery of symptoms, signs, blood eosinophil count, and IgE.

The incidence of epithelial skin neoplasms, such as squamous cell carcinoma and basal cell carcinoma is significantly increasing worldwide. Leisure time solar UV exposure is causative in the overwhelming majority of cases in the general population; however, occupational exposure is responsible for a certain percentage of cases. Employees with a relevant exposure to polycyclic aromatic hydrocarbons in soot, raw paraffin, coal tar, anthracene, pitch or similar substances, to sunlight in outdoor occupations as well as to arsenic and ionizing radiation have a significantly increased risk to develop occupational skin cancer compared to the general population. In the official occupational disease list in the appendix of the German by-law on occupational diseases, the following occupational diseases concerning skin cancer are listed: BK 5102 "skin cancer and carcinoma in situ caused by soot, raw paraffin, coal tar, anthracene, pitch or similar substances" (e.g. various solid paraffins, asphalt and mazut as well as mineral oils, grease, cylinder and drilling oils), BK 5103 "squamous cell carcinoma or multiple actinic keratosis caused by natural UV radiation", BK 1108 "diseases caused by arsenic and its compounds" and BK 2402 "diseases caused by ionizing radiation". For further occupational exposure to carcinogenic substances and potential occupationally acquired skin tumors, no official lists are currently available. These cancers might be considered under a special opt out paragraph in the German Social Law (§ 9 para 2 SGB VII). Tumors in scars after occupational skin trauma or occupational burns are compensated as consequences of work accidents. The current official list of occupational skin cancers and new developments for expert opinions are described in this article.

Superwarfarin poisoning is usually due to chronic occult small-dose exposures and can easily be misdiagnosed and may lead to serious complications. The diagnosis can be confirmed by a concordant history and analyses of blood and urine specimens with the liquid chromatography with tandem mass spectrometry (LC-MS/MS) technique. Several months of continuous treatment with high doses of daily oral vitamin K, as well as other supportive measures, are warranted, especially when repeated laboratory measurements to help predict the treatment period are not available. In this paper, a case of superwarfarin poisoning due to chronic repetitive occupational dermal exposure to commercial rodenticides is presented., Competing Interests: The authors of this paper have no conflicts of interest, including specific financial interests, relationships, and/or affiliations relevant to the subject matter or materials included.

Allergic contact dermatitis is a common diagnosis resulting from exposure to a chemical or chemicals in a patient's personal care products, home, or work environment. Once patch testing has been performed, the education and management process begins. After the causative allergens have been identified, patient education is critical to the proper treatment and management of the patient. This must occur if the dermatitis is to resolve. Detailed education is imperative, and several resources are highlighted. Photoallergic contact dermatitis and occupational contact dermatitis are other considerations a clinician must keep in mind., (Copyright © 2015 American Academy of Dermatology, Inc.

Objectives: We investigate the impact of occupational skin disease consultations among outpatients at the Dermatological Department, University Hospital, Northern Norway., Study Design: From 1997 until 2004, 386 patients with occupational skin disease were examined and given advice on skin care, skin disease treatment, skin protection in further work, and on the legal rights of patients with this disease. Ten to fifteen years later, we wanted to look at these patients in terms of their work situation, the current status of their disease, the help they received from the labour offices, and their subjective quality of life., Material and Methods: In the autumn of 2011 until the spring of 2012, a number of the patients examined in the period from 1997 to 2004 were selected and sent a questionnaire, which they were asked to answer and return, regarding their work situation and the progress and current status of their occupational disease., Results: A total of 153 (77%) patients answered the questionnaire; 71% of these patients were still in work, and further 15% had old-age retired, 13% were working until then; 16% had retired early because of disability; 54% had changed jobs because of their occupational skin disease; 86% of the patients indicated that the skin disease had improved since our previous investigation., Conclusions: Our investigation into patients with occupational skin disease documented that the majority of patients who had received professional dermatological consultation and intervention offers were still in the labour market and had good control of their skin disease 10-15 years later. We discovered that 71% of the patients were still employed. 13% had remained in work until they became old age pensioners. Only 16% dropped out of work because of disability. These high percentages may indicate that our intervention has contributed positively to patients' work conditions and the course of their skin disease.

Background: Data on the epidemiological impact and clinical characteristics of chronic hand eczema in Southern Europe are lacking., Objectives: To estimate the prevalence of chronic hand eczema in its different stages of severity and refractoriness to standard therapy in patients accessing Italian dermatological reference centres, and to evaluate sociodemographic and clinical factors associated with each stage., Methods: A cross-sectional multicentre study was conducted. Adult patients with hand eczema, consecutively accessing 14 centres over a 6-month period, were enrolled. Patients were classified according to disease duration, severity and response to standard therapy with potent topical corticosteroids. Logistical regression was performed to investigate the relationship between sociodemographic and clinical data with different stages of eczema., Results: The total number of participants was 981. Hand eczema was chronic in 83·5% of patients; 21·3% had severe eczema, with 62·0% of these patients refractory to standard therapy. Food processing and related work, the health professions, craft and related trade works (building, plumbing, electrical), hairdressing/beauty and handicraft work were most frequently associated with chronic hand eczema. Severe chronic hand eczema was more likely to be seen in men, older patients and those with less education. Severe and refractory hand eczema was also more likely among the unemployed and patients with allergic rhinitis and/or atopic dermatitis., Conclusions: Chronic hand eczema is frequent among patients with hand eczema accessing dermatology centres. Many patients were severe and refractory to standard therapy. The appropriate identification of hand eczema is the first step in implementing effective and efficient treatments., (© 2014 British Association of Dermatologists.)

Allergy to natural rubber latex (NRL) from Hevea brasiliensis is a relevant occupational health hazard. The use of gloves and products manufactured with latex and environmental allergen exposure in the work environment are risks factors for the development of occupational allergy among different job categories. Healthcare workers have been the most commonly affected, but other professions with exposure to latex products such as hairdressers, cleaners, food handlers and those making natural rubber latex (NRL) products are also at risk of developing occupational allergy. Clinical manifestations of IgE-mediated latex allergy can range from troublesome skin disorders to life-threatening systemic reactions. It is very important to identify the occupational allergic diseases in their early stages in order to implement avoidance strategies. For this purpose, the interventions for prevention should emphasize the importance of latex allergy awareness and surveillance among exposed workforces.

In clinical practice occupational skin diseases usually present as hand dermatitis. Occupationally acquired contact allergies are of eminent relevance in many work place products e.g. skin care products, dyes and paints, epoxy resins or protective gloves. However, not infrequently, a range of other dermatoses of different etiology and localization can be occupationally induced and, at least in Germany, thus be medically treated and--if necessary--compensated for with full coverage by the statutory employers' liability insurance. Examples regarding non-eczematous skin diseases triggered by external factors are psoriatic lesions, cutaneous type-1-allergies, occupationally acquired infections, and dermatoses in other localizations which are occupationally exposed to irritant influences (e.g. feet in workers wearing occlusive safety boots). Moreover, outdoor workers deserve specific attention by the dermatologist if squamous cell carcinomas including precursor lesions like actinic keratoses or Bowen disease have occurred. In Germany, recently the scientific advisory committee to the Ministry of Labor has recommended including these skin cancers caused by occupational solar UV exposure in the national list of occupational diseases. The framework for dermatological preventive care of occupationally-induced inflammatory dermatoses has been continuously improved in the last years. The aim is to reach a similar level of care and preventive measures for patients with occupational skin cancer, including primary preventive workers' education.

Hand dermatitis is a common skin complaint. We use our hands to explore our environment; subsequently, our hands are in frequent contact with potential allergens and irritants. Patients with hand dermatitis may present to their allergist with this complaint. Approaching the diagnosis and treatment of hand dermatitis can be challenging, as both internal and external factors may contribute to the overall condition. Furthermore, the differential diagnosis of hand dermatitis is broad and the cause often multifactorial. Obtaining a thorough history and performing a focused examination may help the clinician differentiate between multiple causes of hand dermatitis. Numerous treatment options exist for hand dermatitis, and new potential treatments are in development as well. We aim to provide the allergist with a streamlined toolkit for help in the diagnosis and management of hand dermatitis.

Background: Hand eczema is often related to high-risk occupations and aggravating exposures in everyday life. The disease is twice as frequent in women as in men, partly because of diverse exposure patterns. Other gender differences may be relevant for treatment and prevention., Objectives: To gain insights into the common features and differences between men and women with hand eczema., Methods: The clinical disease severity of patients (n = 306) attending for dermatological treatment at two settings was assessed with the Hand Eczema Severity Index (HECSI). Self-reported medication adherence, aggravating factors, hand eczema-related consequences and quality of life were obtained from a questionnaire., Results: Men and women had equal clinical severities of disease, with an overall median HECSI of 43. Self-reported medication adherence was equal between the genders, but, among patients aged > 40 years, more reported higher adherence. The impact of disease was larger in women than in men. Women reported significantly more aggravating factors and sick leave. Also, women had a more impaired quality of life than men at equal levels of disease severity, and this could be associated with the higher number of aggravating factors., Conclusion: Gender differences in hand eczema need to be considered in the dermatological treatment and counselling of patients., (© 2014 John Wiley & Sons A/S.

Background: Quality assurance is a task of the medical profession, but it is also a duty of the occupational health insurance (OHI). Data on the interaction quality between physicians practicing occupational dermatology and the OHI are limited., Material and Methods: An online survey was performed in 854 German members of the Working Group on Occupational and Environmental Dermatology in October 2013. Items included demographic data, a judgment on the cooperation between the dermatologists and OHI companies, an economic grading of the current compensation scheme, and prioritization of optimization tasks., Results: 182 members (21.3 % of the invited population) participated in the survey. The cooperation with the OHI companies was judged as "very good" by 10.8 %, as "good" by 56.7  %, as "satisfactory" by 24.2 %, as "sufficient" by 7.0 % and as "inadequate" by 1.3 %. 93.4 % of the interviewed mentioned problems and improvement potentials in the cooperation of their practice or clinic with OHI companies. Main points of criticisms were reimbursement (44.7 %), followed by impairments of the treatment options (36.5 %) and the delay or scope of the treatment in the dermatologist's procedure (29.4 %)., Conclusions: While most physicians practicing occupational dermatology give a positive judgment of their cooperation with OHI companies, quality optimization potentials exist regarding the reimbursement of dermatological services, especially regarding time-intensive counselling in the prevention of occupational skin diseases, in the enablement of diagnostic and therapeutic procedures according to current guidelines and in a timely preventive intervention to use the therapeutic window before chronification of skin diseases may occur., (© 2014 Deutsche Dermatologische Gesellschaft (DDG).

Background: The aim of the present study was to examine the knowledge of skin care and treatment of hand eczema (HE) in a sample of patients with newly reported occupational HE., Materials and Methods: A questionnaire consisting of 13 questions about knowledge of skin care and treatment of HE was sent to all patients with occupational HE reported to the National Board of Industrial Injuries in the period 1 January 2010 to 31 March 2010., Results: Three hundred and seventy individuals, 269 females and 101 males, with a mean age of 39.9 years, responded to the questionnaire (response rate of 73%). The overall percentage of correct answers was 73%. Variables significantly influencing the level of knowledge were sex and age, with a need for more information in males and in patients above the age of 50 years. No significant influence of level of education, eczema activity, previous information about HE, previous or current atopic eczema or dermatology life quality index (DLQI) was found., Conclusion: There is still potential for improvement of the level of knowledge among patients with occupational HE. Special attention should be paid to males and patients above the age of 50 years., (© 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: There is little knowledge about the costs of occupational hand eczema., Objectives: To estimate the societal costs of patients with occupational hand eczema in Germany., Methods: Resource use during the past year, disease severity and quality of life [Dermatology Life Quality Index (DLQI)] were gathered for patients with occupational hand eczema before they entered a special rehabilitation programme. Costs were calculated from the societal perspective. The analysis focused on all patients and the severity groups no signs/mild (group A) and moderate to severe (group B)., Results: One hundred and fifty-one patients were analysed, with a mean age of 44.9~years and a mean DLQI score of 10.9; 64.9% were male. Sickness absence was recorded for 62.9% of all patients (76.4~days on average in the last 12~months). Annual societal costs were €8799 per patient. Indirect costs represented 70% of total costs. Quality of life (DLQI) was statistically different across both severity groups (group A, 7.9; group B, 12.9), but direct treatment costs were not (€2705 versus €2610, respectively). There was a trend towards higher indirect costs in patients in severity group B (group A, €5120; group B, €6796)., Conclusion: The annual societal costs of patients with occupational hand eczema in this study are high, and similar to those for severe psoriasis and atopic dermatitis., (© 2013 John Wiley & Sons A/S.

The diagnosis of occupational contact dermatitis (OCD) and occupational contact urticaria (OCU) is a process that involves fastidious clinical and occupational history taking, clinical examination, patch testing and skin-prick testing. A temporal relationship of work and/or the presence of a rash on the hands only raises suspicion of an occupational cause, and does not necessarily confirm an occupational causation. The identification of allergy by patch or prick tests is a major objective, as exclusion of an offending allergen from the environment can contribute to clinical recovery in the individual worker and avoidance of new cases of disease. This can be a complex process where allergens and irritants, and therefore allergic and irritant contact dermatitis, may coexist. This article provides guidance to healthcare professionals dealing with workers exposed to agents that potentially cause OCD and OCU. Specifically it aims to summarize the 2010 British Occupational Health Research Foundation (BOHRF) systematic review, and also to help practitioners translate the BOHRF guideline into clinical practice. As such, it aims to be of value to physicians and nurses based in primary and secondary care, as well as occupational health and public health clinicians. It is hoped that it will also be of value to employers, interested workers and those with responsibility for workplace standards, such as health and safety representatives. Note that it is not intended, nor should it be taken to imply, that these standards of care override existing statutory and legal obligations. Duties under the U.K. Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1999, the Control of Substances Hazardous to Health Regulations 2002, the Equality Act 2010 and other relevant legislation and guidance must be given due consideration, as should laws relevant to other countries., (© 2013 Crown Copyright BJD © 2013 British Association of Dermatologists This article is published with the permission of the Controller of HMSO and the Queen's Printer for Scotland.)

Skin diseases affecting the hands receive particular individual attention and constitute a considerable emotional burden. Many dermatoses also present with itching of the hands. Itch is often underestimated when it occurs in a comparably limited body area such as the hands. The high occupational significance of the hands in many professions must, nevertheless, be stressed. One of the most frequent diagnoses in itching of the hands is eczema. In the differential diagnosis, less common diseases such as neurological and systemic diseases and adverse drug reactions must also be taken into consideration. Itching of the hands can also be accompanied by other sensations, such as burning, stinging and pain. A thorough history regarding sensations and dysesthesias already allows for a diagnostic classification of the disease in some cases. Itching of the hands requires a careful and thorough diagnostic approach. This forms the basis of a specific and successful therapy which may be adapted stepwise, depending on the underlying cause, and also may require, in addition to causal therapy, symptomatic antipruritic therapy. Therapy should follow the current guidelines for chronic pruritus and hand eczema. This article reviews over the differential diagnosis and therapy of "itching hands"., (© The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.)

Hand dermatitis is commonly seen in primary care, although it is often underdiagnosed. Exogenous causes should always be considered and a detailed environmental and occupational history taken, especially in patients presenting in adulthood. Although not life-threatening, the condition may have significant impact on the patient's quality of life and employment. Refractory cases or those suspected to be due to exogenous workplace agents may need to be referred for further investigation. Hand dermatitis can be treated effectively using pharmacotherapy and prevented by minimising subsequent exposure to irritants and allergens. Occupational skin disorders, once diagnosed, should be notified to the relevant authorities, i.e. the Ministry of Manpower in Singapore.

Eczema, the commonest disorders afflicting the hands, is also the commonest occupational skin disease (OSD). In the dermatology outpatient departments, only the severe cases are diagnosed since patients rarely report with early hand dermatitis. Mild forms are picked up only during occupational screening. Hand eczema (HE) can evolve into a chronic condition with persistent disease even after avoiding contact with the incriminated allergen / irritant. The important risk factors for hand eczema are atopy (especially the presence of dermatitis), wet work, and contact allergy. The higher prevalence in women as compared to men in most studies is related to environmental factors and is mainly applicable to younger women in their twenties. Preventive measures play a very important role in therapy as they enable the affected individuals to retain their employment and livelihood. This article reviews established preventive and therapeutic options and newer drugs like alitretinoin in hand eczema with a mention on the etiology and morphology. Identifying the etiological factors is of paramount importance as avoiding or minimizing these factors play an important role in treatment.

Exposure to hair dyes has long been known as a significant risk factor for development of allergic contact dermatitis among the exposed population as these lead to severe eczema of face and upper trunk in the consumer and hand eczema in hair-dressers. Currently, para-phenylenediamine (PPD) is the main ingredient used in permanent hair color products in the market and is the most important allergen. Prevalence of PPD sensitization is high in patients with contact dermatitis across all continents, with hair dye use being the commonest cause. In order to decrease the burden of disease, use of alternative natural dyeing agents among consumers and use of barrier neoprene gloves among hairdressers should be encouraged apart from stringent legislation to reduce the amount of PPD reaching the consumer.

Ultraviolet (UV) dyes are used as inks in garment printing. Hypersensitivity reactions to these compounds have been reported in the literature. The authors report a case of reaction to UV ink in a patient already on corticosteroid therapy. The patient's clinical course was reviewed along with images of wounds that subsequently developed. The affected areas were debrided and covered with Vaseline gauze and silver impregnated dressings. Epithelium was salvaged in many areas, and regrowth occurred over several weeks in regions of deeper injury. The concurrent use of steroids and the rapidity of the onset of symptoms were not characteristic of hypersensitivity dermatitis, which has previously been reported. The cause of the wounds was likely phototoxicity from radical subtypes in the ink that catalyze the reaction when exposed to UV light.
