[Individual prevention of occupational contact dermatitis: protective gloves and skin protection recommendations as part of the patient management scheme by the public statutory employers' liability insurance]. / Individualprävention beruflicher Kontaktekzeme: Schutzhandschuhe und Hautschutzempfehlungen im berufsgenossenschaftlichen Heilverfahren.

The dermatologist's procedure is a pivotal tool for early recognition of occupational contact dermatitis (OCD), for reporting OCD cases to the statutory accident insurance and for treating the diseases. The employer is in charge of implementing skin protection measures at the workplace. However, in terms of an individual prevention approach it may be necessary to propose targeted skin protection recommendations in specific patient cases. The patient's own skin protection behavior significantly contributes to regenerating and maintaining healthy skin. This behavior includes the use of occupational skin products, and in particular the correct use of appropriately selected protective gloves. Protective gloves are the most important personal protective measure in the prevention of OCD. Prevention services, occupational health and safety specialists, occupational physicians and centers specialized in occupational dermatology can support the identification of suitable protective measures. Nowadays, suitable protective gloves exist for (almost) every occupational activity and exposure. However, improper use in practice can become a risk factor by itself for the skin (e. g., incorrectly used gloves). Therefore, it is of utmost importance to identify application errors, to educate patients in terms of skin protection and to motivate them to perform an appropriate skin protection behavior. With particular focus on protective gloves, this article gives an overview of various types, materials and potentially glove-related allergens, presents strategies for reducing occlusion effects and discusses some typical application errors and solutions.

Standardization of skin cleansing in vivo: part II. Validation of a newly developed Automated Cleansing Device (ACiD).

BACKGROUND: Skin cleansers for occupational use are manufactured for different types and degrees of soiling without common, legally binding requirements for product testing. This leads to different, manufacturer-specific test methods and a lack of comparable information on skin cleansing products. OBJECTIVES: The aim of this investigation was to validate a newly developed standardized automated cleansing device (ACiD) for in vivo evaluation of industrial skin cleansers. METHODS: Two ACiD were tested regarding the intra- and inter-device specific reproducibility of test results. RESULTS: Skin cleansing process carried out by the three independent washing modules which constitute an ACiD-unit and two separate ACiD-units led to highly comparable results. There was no significant difference between the washing modules or between the two separate ACiD-units detected. Only different parameter settings resulted in significantly different detergency. CONCLUSIONS: Intra- and inter-device specific test results of an in vivo model of skin cleansing using the automated cleansing device (ACiD) were reproducible. The long-term aim is a standardized classification of occupational skin cleansing products comparing their skin cleansing effectiveness in relation to their skin irritancy. This might then provide the basis for a rational specific product selection by consumers and may be used as a tool for future product development by manufacturers.

Standardization of skin cleansing in vivo: part I. Development of an Automated Cleansing Device (ACiD).

BACKGROUND: To date, there are no legally binding requirements concerning product testing in cosmetics. This leads to various manufacturer-specific test methods and absent transparent information on skin cleansing products. A standardized in vivo test procedure for assessment of cleansing efficacy and corresponding barrier impairment by the cleaning process is needed, especially in the occupational context where repeated hand washing procedures may be performed at short intervals. METHODS: For the standardization of the cleansing procedure, an Automated Cleansing Device (ACiD) was designed and evaluated. Different smooth washing surfaces of the equipment for ACiD (incl. goat hair, felt, felt covered with nitrile caps) were evaluated regarding their skin compatibility. RESULTS: ACiD allows an automated, fully standardized skin washing procedure. Felt covered with nitrile as washing surface of the rotating washing units leads to a homogenous cleansing result and does not cause detectable skin irritation, neither clinically nor as assessed by skin bioengineering methods (transepidermal water loss, chromametry). CONCLUSIONS: Automated Cleansing Device may be useful for standardized evaluation of the cleansing effectiveness and parallel assessment of the corresponding irritancy potential of industrial skin cleansers. This will allow objectifying efficacy and safety of industrial skin cleansers, thus enabling market transparency and facilitating rational choice of products.
