BACKGROUND. Protein contact dermatitis was originally defined in 1976 by Hjorth and Roed-Petersen as a distinct kind of dermatitis seen in patients with occupational food contact. Even though occupational skin diseases are frequent in Denmark, little attention has been paid to protein contact dermatitis, and the frequency is unknown.
To evaluate the frequency of occupational food-related hand dermatoses and test results in patients occupationally exposed to foods.
This was a retrospective study based on examinations, including skin prick testing and patch testing, performed at the Department of Dermato-Allergology, Gentofte University Hospital, Denmark between 2001 and 2010.
Of all patients (n = 372), 57.0% had irritant contact dermatitis, 22.0% had protein contact dermatitis, 2.4% had contact urticaria, and 1.8% had allergic contact dermatitis. A suggestion for diagnostic criteria is presented. Frequent risk occupations were cooking in restaurants, baking, and kitchen work. Substantially more patients reacted in skin prick testing with fresh foods than with food extracts. Conclusion. Protein contact dermatitis is a frequent disorder among patients who professionally handle foods, and should be considered to be a distinct clinical entity. When diagnosing protein contact dermatitis and in other food-related skin prick testing procedures, it is important to include fresh foods.

ABSTRACT: To elucidate the relationship between seven occupational dermatoses (ODs) and 20 types of work in Greece.
This was a prevalence epidemiologic study of certain ODs among 4,000 workers employed in 20 types of enterprise, in 104 companies, in 2006-2012, using data from company medical records, questionnaires, occupational medical, and special examinations. The χ(2) test was applied to reveal statistically significant relationships between types of enterprises and occurrence of ODs.
A high percentage (39.9%) of employees included in the study population suffered from ODs. The highest prevalence rates were noted among hairdressers (of contact dermatitis: 30%), cooks (of contact dermatitis: 29.5%), bitumen workers (of acne: 23.5%), car industry workers (of mechanical injury: 15%), construction workers (of contact urticaria: 29.5%), industrial cleaning workers (of chemical burns: 13%), and farmers (of malignant tumors: 5.5%). We observed several statistical significant correlations between ODs (acute and chronic contact dermatitis, urticaria, mechanical injury, acne, burns, skin cancer) and certain types of enterprises. There was no statistically significant correlation between gender and prevalence of ODs, except for dermatoses caused by mechanical injuries afflicting mainly men [χ(2) (1) = 13.40, p < 0.001] and for chronic contact dermatitis [χ(2) (1) = 5.53, p = 0.019] afflicting mainly women.
Prevalence of ODs is high in Greece, contrary to all official reports by the Greek National Institute of Health. There is a need to introduce a nationwide voluntary surveillance system for reporting ODs and to enhance skin protection measures at work.

ABSTRACT: Die Proteinkontaktdermatitis ist ein Krankheitsbild, das sich vor allem bei Personen aus der Nahrungsmittelverarbeitung findet. Häufiges Leitsymptom ist ein chronisches Handekzem. Getriggert wird es durch eine IgE-abhängige Nahrungsmittelsensibilisierung, die nach lokalem Kontakt zur Einwanderung von T-Zellen führt, die das Ekzem auslösen. Wegweisend für die Diagnose sind eine entsprechende Anamnese und Klinik sowie der hierzu passende Nachweis einer IgE-abhängigen Sensibilisierung, die sich auch als Kontakturtikaria bis hin zur Kontaktanaphylaxie manifestieren kann. Wir berichten hier über einen 55-jährigen Fleischer mit einer Proteinkontaktdermatitis.

ABSTRACT: The term "eczema" does not refer to a specific disease, but to a syndrome of characteristic clinical features that are common for a heterogeneous group of diseases with various etiology. The difficulty with differentiating various types of eczema is partly due to overlapping, sometimes even conflicting definitions. As the diagnosis is based mainly on clinical picture and history, diagnostic decisions are greatly influenced by beliefs of individual doctors. The aim of the present study was to discuss diverse types of eczema in the light of current knowledge, as well as propose a classification of eczema that could be useful for practical doctors. The proposed etiology-based classification comprises eczema types most relevant in the practice: eczema without identifiable exogenous triggers ("endogenous" atopic eczema), eczema caused by exogenous factors without involvement of specific hypersensitivity reactions (irritant contact dermatitis, microtrauma or friction dermatitis, phototoxic dermatitis and radiation dermatitis), eczema caused by exogenous factors with the involvement of specific hypersensitivity ("exogenous" atopic eczema, allergic contact dermatitis, photoallergic dermatitis, protein contact dermatitis), eczema due to autoimmune reactions (autoimmune eczema, autoimmune progesterone dermatitis), and finally, eczema due to impaired skin homeostasis (seborrhoeic dermatitis, asteatotic dermatitis, stasis dermatitis). Other, not included in this classification terms pertaining eczema are also discussed. In routine usage, sometimes it seems practical to use collective terms combining diseases with different etiology, yet sharing relevant clinical characteristics or legal status, such as nummular eczema, dishydrotic eczema, airborne dermatitis, hand eczema, foot eczema, consort/connubial dermatitis or occupational dermatitis. Key words: eczema, dermatitis, clinical entities, classification.
