Psoriasis predisposition and occupational triggering factors in the appraisal of occupational medical expertises.

BACKGROUND: Psoriasis is an immune-mediated disease with a genetic background. Local psoriatic changes can be triggered by exogenous mechanical or irritant factors. Causative occupational factors have to be distinguished from the spontaneous course of psoriasis in occupational medical evaluations. The objective of this work is to demonstrate the medico-legal grounds for a homogenous assessment. PATIENTS AND METHODS: The presented recommendations were developed in a working group for Occupational and Environmental Dermatology (ABD) and the German contact dermatitis group (DKG) of the German Dermatologic Society (DDG) based on the German medico-legal framework. RESULTS: Causality between the insured activity and the appearance of psoriasis is a prerequisite for the recognition of the occupational nature of the disease. This is the case if the occupational activity is the exclusive or a legally essential contributing factor either for first manifestation or aggravation of the disease. A connection must be denied if everyday events are sufficient to trigger the psoriasis. From 1995 to 2010, 130 cases of psoriasis have been recognized as occupationally related by the German statutory accident insurance. CONCLUSIONS: The appraisal of psoriatic disease in the occupational medical evaluation is subject to the case assessment of the expert witness. In this position paper we present recommendations for a homologous basis for diagnosis, causality assessment, estimation of reduction in earning capacity and rehabilitation of occupational psoriasis.

Secondary prevention of occupational dermatoses: first systematic evaluation of optimized dermatologist's procedure and hierarchical multi-step intervention.

BACKGROUND: In 2011, 25,056 notifications of suspected occupational dermatitis (OD) were submitted to the statutory accident insurance (UVT), predominant by dermatologist's reports. Parallel to the introduction of the improved dermatologist's procedure, the hierarchical multi-step intervention approach to OD was launched within the UVT. It is aimed at ensuring that patients with OD can be allocated to preventive dermatological interventions quickly and appropriately according to the severity of their OD. From 2007-2010, the quality of dermatological interventions as well as the corresponding administrative procedures were evaluated in a unique research project supported by the German Social Accident Insurance. PATIENTS AND METHODS: About 10 % (n = 1 600) of notified cases with suspected OD in 2007 in Germany were analyzed in a random quota sample by occupational dermatologists and administrations. Follow-up was 12 months. If a dermatologist's procedure was initiated after the initial notification, patients' and dermatologists' opinions were obtained by questionnaires. RESULTS: More than 85 % of the OD notifications were submitted by dermatologists and only 1.6 % by occupational physicians. In 88 %, the dermatologist's report was used. Yet, there is room for optimizing procedures: e.g., the clinical and/or occupational relevance of type IV allergies was assessed only in 36.5 % of patients. Job loss due to OD occurred less often if suitable preventive and/or therapeutic strategies (e.g., skin protection seminars) were implemented by the UVT (p = 0.001). Preventive and therapeutic strategies were initiated more often when the dermatologist's report was conclusive, a central element is the outpatient care by a dermatologist. CONCLUSIONS: The research project shows that the quality of dermatological intervention, as well as administrative procedures, can be optimized. Early intervention with suitable preventive and therapeutic strategies in patients with OD should be aimed at, as this is crucial for the outcome of OD.

Safety, effectiveness and comparability of professional skin cleansers.

BACKGROUND: There are no widely-accepted methodical specifications with which to objectify cleansing effectiveness and skin compatibility of occuptional skin cleansing products in Europe. Therefore the German Social Insurance Agency (DGUV) initiated a study with the goal to evaluate such products in view of the potency and the safety of hand cleansers. A market analysis was a part of the project. METHODOLOGY: The product descriptions and safety data sheets of 120 products (5-20/manufacturer) of 11 manufacturers were evaluated between 02/2008 and 04/2008. RESULTS: The manufacturers used mainly ingredients of low irritancy. The declaration of the applied ingredients was in the majority of the cases correctly labeled according to the INCI Declaration. Although there was documentation of skin tolerability for most products, the manufacturers used widely differing tests of skin compatibility. Evidences for cleansing effectiveness were not declared or have not been provided. One manufacturer even promised medical effects of its products. There was no uniform general classification of products making it difficult to identify characteristics of cleansers and choose between them. CONCLUSIONS: Presently, there are no commonly accepted criteria to classify products in view of cleansing effectiveness und skin compatibility. Generally accepted criteria and test methods are needed for the evaluation of hand cleansers in order to provide the possibility of transparency and comparability.
