Epidemiology of patch tested patients with permanent tattoos-A comparative analysis of 9693 IVDK patients (2020-2022)

BACKGROUND

Permanent tattooing is the invasive introduction of tattoo ink (pigments) into the dermis. The ink and aftercare cosmetics applied on pre-damaged skin may contain skin sensitisers.

OBJECTIVES

To identify patient characteristics and the pattern of sensitisation in tattooed patients patch tested within the Information Network of Departments of Dermatology (IVDK).

PATIENTS AND METHODS

Comparative analysis of patient characteristics and reaction frequencies to baseline series allergens in 1648 consecutive patients with and 8045 consecutive patients without permanent tattoos. Non-overlapping 95%-confidence intervals were considered as significant.

RESULTS

Having permanent tattoos was related with female sex, age <40 years, tobacco smoking, atopic dermatitis, (occupational) hand dermatitis and being employed in particular occupational groups (e.g., healthcare workers, mechanics, hairdressers). Sensitisation to nickel was increased in tattooed patients and associated with female sex (OR 4.23 [95%-CI, 3.48-5.18]), age ≥40 years (OR 1.26 [95%-CI, 1.08-1.49]), tobacco smoking (OR 1.19 [95%-CI, 1.01-1.40]) and having permanent tattoos (OR 1.27 [95%-CI, 1.05-1.53]).

CONCLUSIONS

The association between nickel sensitisation and permanent tattoos is probably confounded by past reactions to pierced costume jewellery. Socio-economic factors most probably contribute to the connection between tattoos, tobacco smoking, occupational or hand dermatitis, and being employed in particular occupational groups.

Associations between tobacco smoking status and patch test results-A cross-sectional pilot study from the Information Network of Departments of Dermatology (IVDK)

BACKGROUND

Earlier studies suggested a potential association between tobacco smoking and nickel sensitization, but little is known about other contact allergens.

OBJECTIVES

To investigate the association of smoking status and contact sensitizations as well as subtypes of dermatitis, and to analyse the sensitization profiles of tobacco smokers.

PATIENTS AND METHODS

Within the Information Network of Departments of Dermatology (IVDK), we performed a cross-sectional multicentre pilot study comprising 1091 patch-tested patients from 9 departments, comparing 541 patients with a history of cigarette smoking (281 current and 260 former smokers) with 550 never-smokers.

RESULTS

We could not confirm the previously reported association between nickel sensitization and tobacco smoking. Moreover, sensitizations to other allergens, including colophony, fragrance mix I, Myroxylon pereirae and formaldehyde, were not increased in cigarette smokers compared with never smokers. Hand dermatitis (50.6% vs. 33.6%) and occupational cause (36.2% vs. 22.5%) were significantly more frequent among cigarette smokers compared with never-smokers as shown by non-overlapping 95% confidence intervals.

CONCLUSIONS

Although our study does not allow a firm conclusion on whether smoking status contributes to certain contact sensitizations, it confirms an association of smoking with hand dermatitis and occupational cause.

[Selected aspects regarding social factors in skin diseases]

Skin diseases are complex and cannot be explained solely by genetic or environmental factors but are also significantly shaped by social influences. This review illuminates the bidirectional relationship between social factors and skin diseases, demonstrating how social determinants such as socioeconomic status, living environment, and psychosocial stress can influence the onset and progression of skin conditions. Simultaneously, it explores how skin diseases can affect individuals' social lives and work capability, leading to a cycle of social withdrawal and further deterioration of the condition. The paper describes the need for a holistic approach in dermatology that goes beyond the biomedical perspective and incorporates social factors to develop effective prevention and treatment strategies. The increasing prevalence of skin diseases in Europe and the expected rise in allergies due to climate change make the consideration of social determinants even more urgent. The findings of this review aim to raise awareness of the complex interconnections between social factors and skin health and contribute to reducing social disparities in skin health.

Demographics, characteristics and medical treatment among adults with hand eczema in Denmark. A cross-sectional validation and registry-based study

BACKGROUND

The international classification of diseases, 10th revision (ICD-10) includes several unvalidated diagnostic codes for hand eczema (HE). Knowledge is sparse on HE patient characteristics.

OBJECTIVES

To validate selected HE ICD-10 codes in the Danish National Patient Registry (DNPR) and describe disease characteristics, lifestyle factors and medication use in adult HE patients.

METHODS

Nineteen HE ICD-10 codes were selected and validated based on patient charts. Five cohorts were constructed based on the diagnostic code, DL30.8H (HE unspecified), in the DNPR: (i) patients with DL30.8H code (n = 8386), (ii) patients with DL30.8H code, but without atopic dermatitis (AD) (n = 7406), (iii) sex- and age-matched general population (n = 8386) without HE. Two additional cohorts nested in the DNPR included participants from the Danish Skin Cohort, (iv) patients with DL30.8H code but without AD (n = 1340) and (v) general population cohort (n = 9876).

RESULTS

ICD-10 codes revealed positive predictive values ≥90% except irritant contact dermatitis (unspecified) (79.7%) and hyperkeratotic hand and foot eczema (84.1%). HE patients were most often women, middle-aged or older, of Danish ethnicity, had an atopic medical history and were smokers. Topical corticosteroid prescriptions were almost doubled in HE cohorts compared to general populations.

CONCLUSION

We validated several HE ICD-10 codes and identified important HE patient characteristics.

The Effects of Smoking on the Severity of Atopic Dermatitis in Saudi Arabia

Background Atopic dermatitis (AD) is a well-known inflammatory skin disease that is associated with a family history of other atopic diseases. Tobacco smoking has been found to affect AD as well as several other inflammatory skin diseases. In this study, we aimed to investigate this association and to elucidate the link between dose-dependent tobacco exposure and symptom severity. Methods This cross-sectional study was conducted on individuals from the general population of Riyadh, Saudi Arabia. Data were collected using an online questionnaire. All statistical analyses were performed using RStudio, version 1.1.363 (RStudio, PBC, Boston, Massachusetts, United States). Questions about the participants' age, sex, and occupational status were included. The participants were asked to report their daily handwashing habits and history of atopic diseases. Data on the smoking duration, number of cigarettes smoked per day, and passive exposure were collected. Results A total of 510 participants (41.3 %) reported having AD. Smoking was significantly associated with an increased prevalence of AD. The odds of having AD were 1.78 and 2.27 times higher in occasional smokers (odds ratio (OR) = 1.78, p < 0.05) and daily smokers (OR = 2.27, p < 0.001) than in non-smokers. Neither smoking frequency (p = 0.19) nor duration (p = 0.73) was significantly associated with AD prevalence. Conclusion Smoking is significantly associated with an increased prevalence of AD. Adults should be discouraged from smoking in order to prevent adult-onset AD. The level of nicotine exposure should be measured objectively in future studies.

Programme for prevention of foot dermatoses in patients with work-related skin diseases: Baseline data and first results of a prospective cohort study (OCCUPES)

BACKGROUND

Programmes for prevention of hand dermatoses in patients with work-related skin diseases (WRSD) are well established. Similar interventions for foot dermatoses (FD) are widely missing.

OBJECTIVE

To evaluate the effectiveness of a programme for prevention of FD based on health education in patients with WRSD while investigating the impact and possible causative factors of FD.

METHODS

In a prospective cohort study (OCCUPES), 231 patients with WRSD and FD participating in the programme were recruited. The skin was examined and questionnaires were completed, including assessment of footwear, FD severity, symptoms and health-related quality of life.

RESULTS

The baseline and some early results are presented. A work-related causation of FD was likely in 60 patients (26.0%) with irritant contact dermatitis being the most frequent diagnosis. Work-related FD were associated with male sex (p = 0.012), sweating in footwear (p = 0.004) and wearing of safety footwear (p = 0.013). FD were often long-lasting with a high degree of work-absenteeism, quality of life impairment, itch and pain, particularly in work-related FD.

CONCLUSIONS

Interventions are needed to reduce the burden of FD in patients with WRSD. The programme addresses current shortcomings in prevention of FD. A long-term evaluation of its effectiveness follows.

S2k-Leitlinie Diagnostik, Prävention und Therapie des Handekzems: S2k guideline diagnosis, prevention and therapy of hand eczema

Die S2k‐Leitlinie „Diagnostik, Prävention und Therapie des Handekzems (HE)“ gibt auf der Grundlage eines evidenz‐ und konsensbasierten Ansatzes konkrete Handlungsanweisungen und Empfehlungen für die Diagnostik, Prävention und Therapie des HE. Die Leitlinie wurde auf der Grundlage der deutschen Leitlinie „Management von Handekzemen“ aus dem Jahr 2009 und der aktuellen Leitlinie der European Society of Contact Dermatitis (ESCD) „Guidelines for diagnosis, prevention and treatment of hand eczema“ aus dem Jahr 2022 erstellt. Allgemeines Ziel der Leitlinie ist es, Dermatologen und Allergologen in der Praxis und Klinik eine akzeptierte, evidenzbasierte Entscheidungshilfe für die Auswahl sowie Durchführung einer geeigneten und suffizienten Therapie für Patienten mit Handekzemen zur Verfügung zu stellen. Die Leitlinie basiert auf zwei Cochrane‐Reviews zu therapeutischen und präventiven Interventionen beim HE. Die übrigen Kapitel wurden überwiegend basierend auf nicht systematischen Literaturrecherchen durch die Expertengruppe erarbeitet und konsentiert. Die Expertenkommission bestand aus Mitgliedern von allergologischen und berufsdermatologischen Fachgesellschaften und Arbeitsgruppen, einer Patientenvertretung und Methodikern. Im Rahmen einer Konsensuskonferenz am 15.09.2022 wurden die Vorschläge für die Empfehlungen und Kernaussagen unter Verwendung eines nominalen Gruppenprozesses konsentiert. Der strukturierte Konsensfindungsprozess wurde professionell moderiert. Die vorliegende Leitlinie hat eine Gültigkeit bis zum 22.02.2028.

S2k guideline diagnosis, prevention, and therapy of hand eczema

The consensus-based guideline "Diagnosis, prevention, and treatment of hand eczema (HE)" provides concrete instructions and recommendations for diagnosis, prevention, and therapy of HE based on an evidence- and consensus-based approach. The guideline was created based on the German guideline "Management von Handekzemen" from 2009 and the current guideline of the European Society of Contact Dermatitis (ESCD) "Guidelines for diagnosis, prevention, and treatment of hand eczema" from 2022. The general goal of the guideline is to provide dermatologists and allergologists in practice and clinics with an accepted, evidence-based decision-making tool for selecting and conducting suitable and sufficient therapy for patients with hand eczema. The guideline is based on two Cochrane reviews of therapeutic and preventive interventions for HE. The remaining chapters were mainly developed and consented based on non-systematic literature research by the expert group. The expert group consisted of members of allergological and occupational dermatological professional associations and working groups, a patient representative, and methodologists. The proposals for recommendations and key statements were consented by using a nominal group process during a consensus conference on September 15, 2022. The structured consensus-building process was professionally moderated. This guideline is valid until February 22, 2028.

Effectiveness of a Skin Care Program With a Cream Containing Ceramide C and a Personalized Training for Secondary Prevention of Hand Contact Dermatitis

Background/Objectives: The aim of our study was to investigate the effectiveness of personalized training on skin protection associated with the regular use of ceramide-containing cream (CC) versus other creams (OC) for improving hand contact dermatitis. Methods: We performed a double-center randomized trial that enrolled workers with hand dermatitis. All workers received personalized training. The intervention was 3 times per day application of the study emollient. The control arm used an emollient of choice without ceramide, as needed. The primary outcome was improvement in hand dermatitis at 1 and 3 months of follow-up. Results: In total, 102 patients with hand dermatitis were enrolled in this study. Improvement in dermatitis was found in 40%, 52.5%, 50%, and 63% of OC and CC, at the first and second follow-ups, respectively. The use of CC was significantly associated with an improvement in dermatitis (odds ratios 2.6; 95% confidence intervals 1.30-5.2), analyzed using generalized equation estimation during the follow-up. Conclusion: Our study demonstrated that an educational personalized intervention could improve the signs and symptoms in patients with hand dermatitis, and the use of a CC resulted in a significantly better outcome during the 3 months of follow-up.

Factors associated with depression, anxiety and severe mental illness among adults with atopic eczema or psoriasis: a systematic review and meta-analysis

BACKGROUND

Evidence suggests an association between atopic eczema (AE) or psoriasis and mental illness; however, the factors associated with mental illness are unclear.

OBJECTIVES

To synthesize and evaluate all available evidence on factors associated with depression, anxiety and severe mental illness (SMI) among adults with AE or psoriasis.

METHODS

We searched electronic databases, grey literature databases and clinical trial registries from inception to February 2022 for studies of adults with AE or psoriasis. Eligible studies included randomized controlled trials (RCTs), cohort, cross-sectional or case-control studies where effect estimates of factors associated with depression, anxiety or SMI were reported. We did not apply language or geographical restrictions. We assessed risk of bias using the Quality in Prognosis Studies tool. We synthesized results narratively, and if at least two studies were sufficiently homogeneous, we pooled effect estimates in a random effects meta-analysis.

RESULTS

We included 21 studies (11 observational, 10 RCTs). No observational studies in AE fulfilled our eligibility criteria. Observational studies in people with psoriasis mostly investigated factors associated with depression or anxiety - one cross-sectional study investigated factors associated with schizophrenia. Pooled effect estimates suggest that female sex and psoriatic arthritis were associated with depression [female sex: odds ratio (OR) 1.62, 95% confidence interval (CI) 1.09-2.40, 95% prediction intervals (PIs) 0.62-4.23, I2 = 24.90%, τ2 = 0.05; psoriatic arthritis: OR 2.26, 95% CI 1.56-3.25, 95% PI 0.21-24.23, I2 = 0.00%, τ2 = 0.00] and anxiety (female sex: OR 2.59, 95% CI 1.32-5.07, 95% PI 0.00-3956.27, I2 = 61.90%, τ2 = 0.22; psoriatic arthritis: OR 1.98, 95% CI 1.33-2.94, I2 = 0.00%, τ2 = 0.00). Moderate/severe psoriasis was associated with anxiety (OR 1.14, 95% CI 1.05-1.25, I2 0.00%, τ2 = 0.00), but not depression. Evidence from RCTs suggested that adults with AE or psoriasis given placebo had higher depression and anxiety scores compared with comparators given targeted treatment (e.g. biologic agents).

CONCLUSIONS

Our review highlights limited existing research on factors associated with depression, anxiety and SMI in adults with AE or psoriasis. Observational evidence on factors associated with depression or anxiety in people with psoriasis was conflicting or from single studies, but some identified factors were consistent with those in the general population. Evidence on factors associated with SMIs in people with AE or psoriasis was particularly limited. Evidence from RCTs suggested that AE and psoriasis treated with placebo was associated with higher depression and anxiety scores compared with skin disease treated with targeted therapy; however, follow-up was limited. Therefore, long-term effects on mental health are unclear.

Lifestyle factors and hand eczema: a systematic review and meta‐analysis of observational studies

Evidence regarding the association between lifestyle factors and hand eczema is limited.To extensively investigate the association between lifestyle factors (smoking, alcohol consumption, stress, physical activity, body mass index, diet, and sleep) and the prevalence, incidence, subtype, severity, and prognosis of hand eczema, a systematic review and meta‐analysis were conducted in accordance with the Meta‐analysis Of Observational Studies in Epidemiology consensus statement. MEDLINE, Embase, and Web of Science were searched up to October 2021. The (modified) Newcastle‐Ottawa Scale was used to judge risk of bias. Quality of the evidence was rated using the Grades of Recommendation, Assessment, Development and Evaluation approach. Eligibility and quality were blindly assessed by two independent investigators; disagreements were resolved by a third investigator. Data were pooled using a random‐effects model, and when insufficient for a meta‐analysis, evidence was narratively summarized. Fifty‐five studies were included. The meta‐analysis (17 studies) found very low quality evidence that smoking is associated with a higher prevalence of hand eczema (odds ratio 1.18, 95% confidence interval 1.09‐1.26). No convincing evidence of associations for the other lifestyle factors with hand eczema were found, mostly due to heterogeneity, conflicting results, and/or the limited number of studies per outcome.

Hand eczema and lifestyle factors in the Dutch general population: Evidence for smoking, chronic stress, and obesity

Background

Several risk factors, among other lifestyle factors, have been suggested for hand eczema (HE).

Objectives

To investigate a possible association between HE and lifestyle factors, including smoking, alcohol consumption, stress, body mass index (BMI), waist circumference, physical activity, diet, and amount of sleep in the Dutch general population.

Methods

Data from the large population‐based LifeLines Cohort Study was used. Individuals with HE in the past year were identified by a cross‐sectional questionnaire in 2020. At baseline, information on lifestyle factors was collected.

Results

In total 57 046 individuals were included in the present analysis. Smoking ≥8 cigarettes/day, and smoking ≥15 pack years showed a positive association with HE in the past year. In addition, chronic stress, a BMI >30 kg/m², and a waist circumference of >90 cm were positively associated with HE in the past year.

Conclusions

The current study indicates that lifestyle factors are associated with HE. Advice regarding lifestyle factors might contribute to enhance overall health, of which HE might possibly benefit in conjunction. Further studies should also focus on the association between lifestyle factors and the severity and prognosis of HE rather than on occurrence alone.

Secondary and Tertiary Prevention: Medical Rehabilitation

Allergies are a major public health burden, and targeted measures are required in terms of prevention and treatment. The most common allergic conditions encompass atopic dermatitis (AD), food allergy (FA), allergic asthma (AA), and allergic rhino-conjunctivitis (AR). Primary prevention aims at preventing the onset of allergic disease, before the disease process begins. Secondary prevention aims at preventing progression and exacerbation of allergic disease whereas tertiary prevention aims at reducing disease burden in patients with established disease, by allergen immunotherapy (AIT) or medical rehabilitation. Rehabilitation programs are used for treatment of AA and AD and usually consist of extensive patient assessment, optimization of treatment management, patient education, and behavioral interventions, ideally involving a multidisciplinary treatment team and sometimes provided in a specific climate, usually alpine or maritime. Similarly, prevention of occupational skin diseases requires interdisciplinary approaches on the level of secondary and tertiary preventive intervention; if this is provided, then prevention programs have proven highly (cost-) effective. Unfortunately, the recently published Minimal Standards of Prevention of these dermatoses, underlining especially the importance of meticulous allergological diagnosis and subsequent multidisciplinary patient education, are so far being adhered to only in very few European countries.

Treatment with alitretinoin in patients taking part in a tertiary individual prevention program for work-related skin diseases

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.

Guidelines for the Diagnosis, Treatment, and Prevention of Hand Eczema

Hand eczema is a common condition associated with significantly impaired quality of life and high social and occupational costs. Managing hand eczema is particularly challenging for primary care and occupational health physicians as the condition has varying causes and both disease progression and response to treatment are difficult to predict. Early diagnosis and appropriate protective measures are essential to prevent progression to chronic eczema, which is much more difficult to treat. Appropriate referral to a specialist and opportune evaluation of the need for sick leave are crucial to the good management of these patients. These guidelines cover the diagnosis, prevention, and treatment of chronic hand eczema and highlight the role that primary care and occupational health physicians can play in the early management of this disease.

Effectiveness of secondary prevention in metalworkers with work-related skin diseases and comparison with participants of a tertiary prevention program: A prospective cohort study

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.

Factors influencing prognosis for occupational hand eczema: new trends

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.

Interdisciplinary and multiprofessional outpatient secondary individual prevention of work-related skin diseases in the metalworking industry: 1-year follow-up of a patient cohort

Background

In Germany, work-related skin diseases are predominant within the spectrum of reported occupational diseases. Metal workers are among the high-risk professions. Offering effective prevention programs to affected patients is of utmost importance to avoid deterioration of the disease and job loss. We conducted a 1-year follow-up in patients who participated in a multidisciplinary, complex outpatient prevention program representing a standard procedure of patient care by the respective statutory accident insurance.

Methods

The multi-component prevention program consists of multiprofessional individual patient counseling, a structured skin protection seminar in a group, as well as workplace visits and on-site counseling in terms of appropriate skin protection (e.g. gloves). An observational study with a 1-year follow-up and four measurements (T1-T4, longitudinal pre/post-test design) including dermatological examinations and standardized written questionnaires was conducted between 2013 and 2016 to assess changes over time regarding job loss and disease severity.

Results

Data from 94 patients (87 male, mean age: 45.4 years) were included in the analysis. One year after the skin protection seminar (T4), 83 patients (88.3%) remained in their original professional metalworking activity and four patients (4.3%) had given up their profession because of their skin disease. At baseline (T1), irritant contact dermatitis of the hands was the most frequent diagnosis (80.7%). Methods for self-reported disease severity showed good correlation with the clinical gold standard at T1 and T2 (dermatological examination with the Osnabrück Hand Eczema Severity Index / OHSI), and a significant decrease of the self-reported disease severity was found over time from T1 to T4 (p < 0.001). Further results indicate an improved self-perceived disease control and an overall satisfaction with the prevention program.

Conclusions

The results of this observational study demonstrate that the comprehensive prevention program positively influences the course of work-related skin diseases, increases the possibility to continue working in a “high-risk” profession and improves the disease management of metal workers. In the long term, the prevention program may lead to cost savings by preventing high therapy costs or professional retraining.

An updated review of clinical methods in the assessment of ageing skin - New perspectives and evaluation for claims support

With the advancement of skin research, today's consumer has increased access to an informed understanding of ageing skin and its appendages, together with a plethora of targeted products to meet such needs. In recent years, increased legislative demands for quality evidential claims support have led not only to the development and validation of clinical methods to measure and quantify ageing skin, but also a clearer understanding of the skin ageing process-especially the impact of both its internal and external environments-as well as a tougher stance on clearly unjustifiable claims. Traditional testing methods used to research and evaluate anti-ageing products claim to employ sophisticated instruments. Today, however, since the term anti-ageing can be considered a misnomer, intelligent use of combined more advanced clinical methods has enabled the development of technologically improved consumer products providing enhanced efficacy and targeted performance. Non-invasive methods for the assessment and quantification of the causes of ageing skin provide tools to the clinical researcher as defined by key clinically observed ageing parameters. Where evidence requires additional support, a number of clinical procedures evaluating ageing skin and hair products are combined with invasive procedures, thus enabling an added value to product claims. As discussed herein, given the enhanced understanding of ageing, we provide an update to our previous reviews of clinical methods used in the assessment of skin ageing, to include the wider aspects of environmental exposure; skin pigmentation; microbiome disturbance; surface topography; colour, radiance, and pH; and structural integrity-all requiring a disciplined approach to their use in dermatological investigations and product claims evidence.

The association of smoking with contact dermatitis and hand eczema - a review

Given the high prevalence of allergic contact dermatitis (ACD), irritant contact dermatitis (ICD), hand eczema (HE), and smoking, and the impact that smoking has on skin disease, the authors reviewed the existing literature to assess the association between smoking and contact dermatitis or hand eczema. Using the PubMed and SCOPUS databases, a literature search identified articles related to allergic contact dermatitis, irritant contact dermatitis, and hand eczema and a possible association with smoking. The search period included articles prior to and including April 2016. Seven of eight articles described a positive relationship between smoking and allergic or irritant contact dermatitis, while nine of nineteen articles found a positive association between smoking and hand eczema. Published studies document that smoking may be an important risk factor for both allergic and irritant contact dermatitis as well as hand eczema.

Smoking and Hand Dermatitis in the United States Adult Population

Background

Hand dermatitis is a common chronic relapsing skin disease resulting from a variety of causes, including endogenous predisposition and environmental exposures to irritants and allergens. Lifestyle factors such as smoking have been implicated in hand dermatitis.

Objective

To evaluate the association between tobacco exposure and hand dermatitis using the 2003~2004 National Health and Nutrition Examination Survey (NHANES) database.

Methods

Data were retrieved and analyzed from 1,301 participants, aged 20~59 years, from the 2003~2004 NHANES questionnaire study who completed health examination and blood tests. Diagnosis of hand dermatitis was based on standardized photographs of the dorsal and palmar views of the hands read by two dermatologists.

Results

There were 38 diagnosed cases of active hand dermatitis out of the 1,301 study participants (2.9%). Heavy smokers (>15 g tobacco daily) were 5.11 times more likely to have active hand dermatitis (odds ratio [OR], 5.11; 95% confidence interval [CI], 1.39~18.88; p=0.014). Those with serum cotinine >3 ng/ml were also more likely to have active hand dermatitis, compared with those with serum cotinine ≤3 ng/ml (OR, 2.50; 95% CI, 1.26~4.95; p=0.007). After adjusting for confounding factors such as age, atopic diathesis, occupational groups, and physical activity, the association between tobacco exposure and active hand dermatitis remained significant.

Conclusion

Smoking has a significant association with the presence of active hand dermatitis. It is important to consider smoking cessation as part of management of hand dermatitis.

Utilization of Preventive Health Care in Adults and Children With Eczema

INTRODUCTION

Chronic disease is a barrier to delivery of preventive health care and health maintenance. However, health behaviors of adults and children with eczema, a chronic skin disorder, have not been examined. This study examined associations of eczema with vaccination, disease screening, health maintenance, and healthcare utilization.

METHODS

This study investigated 34,613 adults and 13,298 children from the 2012 National Health Interview Survey, a prospective questionnaire-based study. Data were analyzed between August 2014 and January 2015.

RESULTS

Adult eczema was associated with higher odds of vaccination for tetanus (OR [95% CI]=1.37 [1.22, 1.54]); influenza (1.23 [1.10, 1.37]); hepatitis A (1.21 [1.04, 1.41]) and B (1.21 [1.07, 1.35]); human papilloma virus (1.66 [1.32, 2.08]); and pneumonia (1.35 [1.19, 1.54]), but not herpes zoster virus (1.07 [0.87, 1.31]). Adult eczema was associated with increased measurement of blood glucose (1.29 [1.16, 1.44]); cholesterol (1.19 [1.06, 1.34]); blood pressure (1.84 [1.56, 2.08]); and HIV infection (1.50 [1.34, 1.70]), but not Pap smears (1.11 [0.95, 1.30]); colon cancer screening (p=0.17); or mammograms (p=0.63). Adults with eczema were more likely to interact with general doctors, mid-level providers, mental health professionals, eye doctors, podiatrists, chiropractors, therapists, obstetrician/gynecologists, and other specialists (p≤0.01). Childhood eczema was associated with higher rates of vaccination for influenza (p<0.0002); well child checkups (p=0.002); and interaction with most types of healthcare providers (p≤0.01). Many associations remained significant in multivariate models controlling for sociodemographics and healthcare interaction frequency.

CONCLUSIONS

Eczema in adults and children is associated with greater utilization of preventive health care and health maintenance, but not cancer screening.
