Occupational food-related hand dermatoses seen over a 10-year period.
ABSTRACT 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: Manual labor employment occurs in environments with exposures likely to impact skin-related quality of life (SRQOL). The objectives of this paper are to (1) document the dimensions of SRQOL, (2) examine its association with skin symptoms, and (3) identify the predictors of SRQOL in Latino manual workers. A population-based survey of 733 Latino manual workers obtained Dermatology Life Quality Index (DLQI) and skin symptoms in the prior year. Two-thirds of workers were employed in production. Skin symptoms in prior year were reported by 23%. Impaired SRQOL was reported by 23%. In multivariate analyses, reduced SRQOL was associated with age, occupation, childhood indigenous language use, and experience of skin symptoms in the prior year. Despite overall high SRQOL exposures in some immigrant occupational groups produce reduce SRQOL. This rural, immigrant population faces significant obstacles to obtaining dermatological care; efforts are needed to improve their SRQOL. Am. J. Ind.

ABSTRACT: Information on the presence of contact allergens and irritants is crucial for the diagnosis of occupational contact dermatitis. Ingredient lists and Material Safety DataSheets (MSDSs) may be incomplete. To evaluate the workability of a systematic exposure assessment in consecutive patients with suspected occupational contact dermatitis, and to study how it could potentially aid correct diagnostic classification. A tool for systematic stepwise assessment of exposures in the work environment was developed, consisting of six steps spanning medical history and workplace visits. The programme included 228 consecutive patients diagnosed with occupational contact dermatitis; all patients underwent a clinical examination, the stepwise exposure assessment, and extensive patch and prick testing. Of the participants, 48.2% were classified as having occupational allergic contact dermatitis. The diagnosis was made at the stepwise exposure assessment for 50.0% of patients at Step 1 (medical history) and for 34.5% at Step 2 (ingredient labelling/MSDS). We found 132 different occupational allergens of relevance to the patients' eczema, of these, 78.0% were allergens not included in the European baseline series. Systematic stepwise exposure assessment provides information that results in the identification of occupational allergies caused by allergens not included in the European baseline series in a substantial number of patients.Contact Dermatitis 09/2013; 69(3):153-63. · 2.93 Impact Factor

ABSTRACT: A commonly encountered skin disorder in outpatient dermatology practice is hand dermatitis. In a considerable subset of patients, hand dermatitis can be a major source of prolonged distress when a pattern of chronicity develops due to repeated exposure to a variety of potential etiological factors. Most of the etiological factors are exogenous in nature. Hand dermatitis is an equal opportunity disease that affects both genders and occurs in individuals from all ethnic and cultural backgrounds. It is important to note that the term hand dermatitis does not refer to one specific diagnostic entity. Rather, hand dermatitis refers to multiple patterns of clinical disease that can be induced by a variety of exogenous sources. Occupational exposures with inadequate hand protection may be an important cause of epidermal barrier disruption, and in some cases contact allergy may be the primary cause or contribute to chronic hand dermatitis. In certain individuals, endogenous sources, such as atopic skin, cutaneous allergy (eczematous pattern), or skin hypersensitivity (urticarial pattern), may innately create predisposition to the development of hand dermatitis. Hand dermatitis can become a chronic problem that is often difficult to manage effectively. As consistency with hand protection and avoidance of irritant and allergenic contactants are integral to the effective treatment of chronic hand dermatitis, there is a high dependence on consistent patient adherence. Regardless of the etiological factors causing chronic hand dermatitis, lack of consistent hand protection is often a major reason why therapeutic results are suboptimal in some cases as exposure to the causes of the hand dermatitis are not adequately prevented. Regular wearing of protective gloves is not always feasible depending on the occupation, and although topically applied skin barrier protectants may be helpful in some cases, scientific data are generally limited with many products. This article provides an overview of hand dermatitis, reviews data supporting the therapeutic benefit of a specific barrier protection hand cream, and discusses ingredient modifications to the original formulation. The newer formulation does not alter the skin barrier protection components; however, the new ingredients were selected to add barrier repair properties to the original product, which was designed only as a skin barrier protectant.Journal of Clinical and Aesthetic Dermatology 02/2014; 7(2):40-48.
