Background: Blue-collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce.
Objectives: To investigate allergic contact dermatitis in blue-collar workers with dermatitis registered by the Danish Contact Dermatitis Group.
Methods: A retrospective analysis of patch test data from 1471 blue-collar workers and 1471 matched controls tested between 2003 and 2012 was performed.
Background: Hand eczema is a common disease, and continuous preventive skin protection and skin care must be adopted to prevent a chronic course. Hand eczema is not a uniform disease, and counselling must therefore be individually tailored.
Objectives: To evaluate the effectiveness of a nurse-led counselling programme, the Healthy Skin Clinic, emphasizing the patient's self-management, resources, and risks.
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 identify sensitization to the most common allergens associated with the occupation of hairdressing.
Methods: Patch test results of 399 hairdressers and 1995 matched controls with contact dermatitis, registered by the Danish Contact Dermatitis Group between January 2002 and December 2011, were analysed.
Background: Hand eczema has a one-year prevalence of approximately 10 % in the general Danish population. Often the disease becomes chronic with numerous implications for the individual's daily life, occupation and quality of life. However, no guidelines of self-management recommendations beyond the acute stage are given.

Objectives: To characterize painters with contact dermatitis and identify the most common allergens associated with the occupation. Materials and methods.
Background: Epoxy resin monomers are strong skin sensitizers that are widely used in industrial sectors. In Denmark, the law stipulates that workers must undergo a course on safe handling of epoxy resins prior to occupational exposure, but the effectiveness of this initiative is largely unknown.
Objectives: To evaluate the prevalence of contact allergy to epoxy resin monomer (diglycidyl ether of bisphenol A; MW 340) among patients with suspected contact dermatitis and relate this to occupation and work-related consequences.
Systemic contact dermatitis is an inflammatory skin disease that may occur in persons with contact allergy when they are exposed to the hapten orally, transcutaneously, per rectum, intravesically, intravenously, or by inhalation. The most common causes of systemic contact dermatitis are drugs used both topically and systemically. Other causes are ubiquitously occurring haptens, such as the metals nickel, cobalt, gold, and chromate, and aromatic substances such as spices.
View Article and Find Full Text PDFBackground: No generally accepted classification scheme for hand eczema exists. The Danish Contact Dermatitis Group recently developed a guideline defining common clinical types and providing criteria for aetiological types.
Objectives: To test the concepts of this guideline in a group of hand eczema patients.
Background: Classification of hand eczema has traditionally been based both on aetiology and clinical appearance. For 20% of cases, the aetiology is unknown.
Objectives: To suggest a classification based on well-defined aetiology as well as on predefined clinical patterns and on the dynamics of hand eczema.
Background: Fragrances frequently cause contact allergy, and cosmetic products are the main causes of fragrance contact allergy. As the various products have distinctive forms of application and composition of ingredients, some product groups are potentially more likely to play a part in allergic reactions than others.
Aim: To determine which cosmetic product groups cause fragrance allergy among Danish eczema patients.
Background: Fragrance mix II (FM II) is a relatively new screening marker for fragrance contact allergy. It was introduced in the patch test baseline series in Denmark in 2005 and contains six different fragrance chemicals commonly present in cosmetic products and which are known allergens.
Aim: To investigate the diagnostic contribution of including FM II in the baseline series by comparing it with other screening markers of fragrance allergy: fragrance mix I (FM I), Myroxylon pereirae and hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC).
The use of nickel in certain consumer goods has been regulated in Denmark since 1990. The aim of this study was to reveal the clinical characteristics of nickel-allergic patients seen in seven private dermatology clinics and to identify current sources of nickel that may elicit nickel dermatitis. During 2006 to 2007, 634 patients with dermatitis aged 17-91 years were patch-tested and completed a questionnaire including a question about the occurrence of dermatitis following skin contact with ear-rings or ear-pins, watches, buttons or metal clasps (i.
View Article and Find Full Text PDFThe terminology of eruptive, symmetric, vesicular, and/or bullous dermatitis on the palms and/or palmar aspects or sides of the fingers includes the terms pompholyx, dyshidrosis, and dyshidrotic eczema. This article presents the case for a standard, broad definition of this condition and reviews the epidemiology, clinical features, etiology, and treatment of acute and recurrent vesicular hand dermatitis with special emphasis on endogenous causes.
View Article and Find Full Text PDFBackground: The preservative methyldibromo glutaronitrile (MDBGN) has been banned, first from stay-on, and later from rinse-off cosmetics, in the EU countries because of increasing rates of contact allergy.
Objectives: To evaluate the frequency of contact allergy to MDBGN among patients patch tested by the Danish Contact Dermatitis Group just before and following regulatory decisions.
Patients/methods: The data set comprised 19 279 consecutive eczema patients patch tested from 2003-2007 with MDBGN 0.
Background: Hand eczema is a common dermatosis, often with a chronic course.
Objective: To follow a well-described cohort of patients with hand eczema for 5 years.
Patients And Methods: 522 consecutive hand eczema patients (175 men and 347 women) seen in a private practice of dermatology were sent a questionnaire once a year for 5 years.
Background: Hand eczema is a common dermatosis. The course is often protracted. The prognosis is not well described.
