The prevalence of hand dermatitis among intensive care unit nurses.

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

2-Cyanoethyl dimethyldithiocarbamate, a new contact allergen found in accelerator-free nitrile gloves.

BACKGROUND: Allergic contact dermatitis (ACD) from rubber glove usage is usually caused by rubber additives such as the accelerators. However, in analyses of the suspected gloves, ordinary rubber allergens are not always found. Accelerator-free rubber gloves are available, but some patients with accelerator allergy do not tolerate them and might also be patch test positive to them. OBJECTIVES: To identify and chemically characterize a new allergen, 2-cyanoethyl dimethyldithiocarbamate (CEDMC), in rubber gloves. We describe two patient cases: patient 1 that led us to the identification of CEDMC and patient 2 with occupational ACD caused by CEDMC. METHODS: The patients were examined with patch testing including baseline and rubber series, and their own rubber gloves. High-performance liquid chromatography (HPLC) was used for chemical analysis of rubber gloves. The allergen was synthesized and identified by nuclear magnetic resonance, mass spectrometry and infrared spectrometry, and tested on patient 2. RESULTS: CEDMC was identified by HPLC in a nitrile glove associated with hand eczema in patient 1. Patient 2 whose nitrile gloves contained CEDMC was patch test positive to CEDMC. CONCLUSIONS: CEDMC is a new contact allergen in nitrile gloves and probably forms during vulcanization from residual monomer acrylonitrile and rubber additives.

Professional Cleaners' and Healthcare Workers' Ability to Recognize Hand Eczema.

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

Dermatophytes and skin dermatophytoses in Southeast Asia-First epidemiological survey from Cambodia.

BACKGROUND: Dermatomycoses count to the most frequent dermatoses in Cambodia. OBJECTIVES: The aim of this survey was to investigate the occurrence of dermatophytes in this Southeast Asian country. METHODS: From June 2017 to July 2018, skin scrapings were taken from 67 patients with superficial dermatophytosis for mycological diagnostics. Identification of dermatophytes was confirmed by sequencing of the 'internal transcribed spacer'-(ITS) region of the rDNA, and the gene of the Translation Elongation Factor (TEF)-1α. RESULTS: Patients were suffering from tinea corporis and tinea inguinalis/cruris 42/67 (63%), tinea capitis/faciei 14/67 (21%), tinea corporis/capitis/faciei 6/67 (9%), tinea manuum/pedis 2/67 (3%), tinea pedis 2/67 (3%) and tinea manuum 1/67 (1%). Both, by culture and/or PCR, a dermatophyte was detected in 52 (78%) out of 67 samples. Culture positive were 42 (81%) of 52, PCR positive were 50 (96%). The following dermatophytes were found: Trichophyton (T.) rubrum, 36/52 strains (69%, 29 by culture), T. mentagrophytes/T. interdigitale (TM/TI) 9/52 (17%, six by culture) and Microsporum (M.) canis 5/52 strains (10%, by culture). One strain of Nannizzia (N.) incurvata 1/52 (2%) and N. nana 1/52 (2%) was isolated. Based on sequencing, we demonstrated that two T. mentagrophytes strains out of the nine TM/TI represented the new ITS genotype XXV Cambodia. We found one T. mentagrophytes strain genotype VIII (now, reclassified as T. indotineae). This isolate was terbinafine resistant, and it exhibited the amino acid substitution Phe397Leu in the squalene epoxidase. Three strains of T. interdigitale genotype II* were isolated. CONCLUSION: This is the first survey on epidemiology of dermatophytes in Cambodia. Currently, T. rubrum represents the most frequent species in Cambodia. One Indian strain genotype VIII T. mentagrophytes was found. A highlight was the first description of the new T. mentagrophytes genotype XXV Cambodia.

Water, soap, and hand-disinfectant exposure during the COVID-19 pandemic and self-reported hand eczema in frontline workers: A cross-sectional study.

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

Comparison of the effect of topical triamcinolone 0.1% cream with sulfur 2.0% cream in the treatment of patients with hand eczema: A randomized controlled trial.

BACKGROUND: Hand eczema (HE) is a common and heterogeneous condition. It has a wide range of etiologies and clinical manifestations. In this study the efficacy of triamcinolone 0.1% cream and sulfur 2% creams was compared in treating patients with HE. METHODS: This randomized, triple-blind clinical trial was performed on 70 patients with HE (including 70 right and 70 left hands). In this study, two creams were used including triamcinolone 0.1% and sulfur 2.0%. Patients were treated with these creams twice a day (once in every 12 h) for 4 weeks. Follow-up was 4 weeks after treatment. Hand Eczema Severity Index (HECSI), itching, dryness, burning sensation, and erythema scores were collected three times during the study and compared between treatment regimens. RESULTS: Findings showed that both triamcinolone (0.1%) and sulfur (2.0%) creams could significantly reduce the scores of HECSI, itching, dryness, burning sensation, and erythema, and the therapeutic effects lasted for at least 4 weeks after cessation of topical treatment. CONCLUSION: Topical sulfur cream (2.0%) is as effective as triamcinolone (0.1%) cream in treatment of HE without any prominent adverse reactions.

Notification of hand eczema as an occupational disease among Danish hairdressers: a national survey on patients' perception.

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

Dupilumab treatment improves signs, symptoms, quality of life, and work productivity in patients with atopic hand and foot dermatitis: Results from a phase 3, randomized, double-blind, placebo-controlled trial.

BACKGROUND: Despite high disease burden, systemic treatment options for patients with atopic hand and/or foot dermatitis (H/F AD) are limited. OBJECTIVES: To evaluate efficacy and safety of dupilumab in H/F AD using specific instruments for assessing disease severity on hands and feet. METHODS: In this multicenter phase 3 trial, adults and adolescents with moderate-to-severe H/F AD were randomized to dupilumab monotherapy (regimen approved for generalized AD), or matched placebo. The primary endpoint was proportion of patients achieving Hand and Foot Investigator's Global Assessment score 0 or 1 at week 16. Secondary prespecified endpoints assessed the severity and extent of signs, symptom intensity (itch, pain), quality of life, and sleep. RESULTS: A total of 133 patients (adults = 106, adolescents = 27) were randomized to dupilumab (n = 67) or placebo (n = 66). At week 16, significantly more patients receiving dupilumab (n = 27) than placebo (n = 11) achieved Hand and Foot Investigator's Global Assessment score 0 or 1 (40.3% vs 16.7%; P = .003). All other prespecified endpoints were met. Safety was consistent with the known AD dupilumab profile. LIMITATIONS: Short-term, 16-week treatment period. CONCLUSION: Dupilumab monotherapy resulted in significant improvements across different domains of H/F AD with acceptable safety, supporting dupilumab as a systemic treatment approach for this often difficult to treat condition.

The management of Chronic Hand Eczema: A retrospective patient record review.

BACKGROUND: Chronic Hand Eczema (CHE) is a heterogeneous fluctuating inflammatory disease that represents a significant burden. Effective treatment options for moderate to severe CHE are limited. OBJECTIVES: To assess how patients with moderate to severe CHE are treated in clinical practice. METHODS: A retrospective, physician-led patient record review assessed the demographic, clinical and treatment characteristics of patients aged ≥18 years with CHE across seven countries. Each participating physician was requested to review records for their three most recent patients with moderate to severe CHE treated with a topical or systemic therapy. RESULTS: A total of 264 physicians, of whom 88.6% were dermatologists and 70.1% were predominantly or partly hospital-based, reviewed the records of 792 patients. Signs were present on hands only in 56.4% of patients and the mean time on current treatment was 16.7 months. Overall, 62.9% of patients received systemic therapy and almost one-quarter (23.4%) were treated with a biologic; 28.6% of patients were only treated with topical corticosteroids and/or topical calcineurin inhibitors. CONCLUSION: In patients with moderate to severe CHE, most received systemic therapy with one-quarter on biologic therapy. However, given that many of these treatments have limited evidence of efficacy in CHE, there is a need for studies specifically in patients with CHE as well as new therapeutic options.

Melanoma lentiginoso acral: revisão de literatura / Acral lentiginous melanoma: literature review

O melanoma acral é um subtipo de câncer de pele melanoma que ocorre nas regiões palmoplantar e ungueal. É mais frequente nos indivíduos de fototipos elevados e, além da exposição solar, possui outros fatores de risco envolvidos para a ocorrência, alguns ainda pouco conhecidos. O melanoma acral apresenta padrão de crescimento lentiginoso, no entanto, associa-se a um ruim prognóstico em detrimento do atraso no diagnóstico. Esse atraso pode ser atribuído às características clínicas distintas dos melanomas de outras localizações e à localização peculiar. O tratamento da doença localizada baseia-se na exérese cirúrgica de todo o tumor com margens adequadas, que resulta, por vezes, em grandes defeitos cirúrgicos e com difícil reconstrução. Na doença avançada, a terapia sistêmica é uma alternativa terapêutica e de controle da doença. O advento da imunoterapia e das terapias alvo impactou positivamente na sobrevida global desses pacientes. Este trabalho revisa de forma sucinta o que há na literatura sobre o melanoma acral, com foco principalmente nas peculiaridades clínicas

Acral melanoma is a subtype of melanoma skin cancer that occurs on the hands, feet and nail units. It is more common in individuals with high phototypes and, in addition to sun exposure, there are other risk factors involved in its occurrence, some of which are still unknown. Acral melanoma presents a lentiginous growth pattern; however, it is associated with a poor prognosis at the expense of delayed diagnosis. This delay may be attributed to the distinct clinical characteristics of melanomas from other locations and their peculiar location. Treatment of localized disease is based on surgical excision of the entire tumor with adequate margins, which sometimes results in large surgical defects that are difficult to reconstruct. In advanced disease, systemic therapy is a therapeutic and disease control alternative. The advent of immunotherapy and targeted therapies has positively impacted the overall survival of these patients. This work briefly reviews what is available in the literature on acral melanoma, focusing mainly on clinical peculiarities
