    Notes: Skin hyperirritability to irritants as well as atopy are considered to be predisposing factors for contact dermatitis. The aim of the study was to evaluate whether these predictive factors are independent or whether they are so closely related that one could possibly replace the oilier. 205 metalworker trainees underwent skill examination for skin atopy, including standardised questionnaire, clinical examination of the skin and a series of skin irritability tests. These tests included measurements of transepidermal water loss (TEWL) before and after irritation with 3 different irritants: sodium lauryl sulfate (SLS), dimethylsulfoxide (DMSO) and sodium hydroxide (NaOH). The results of the linear regression analysis demonstrate that skin atopy is not associated with increased skin irritability, as assessed by the irritability testing methods presented.

    Notes: The purpose of this study was to determine the frequency of responses to selected fragrance materials in patients who were fragrance sensitive. 178 patients were evaluated in 8 centers worldwide with a fragrance mix (FM) and 20 other fragrance materials. Reaction to the fragrance mixture (FM) occurred in 78.7% of the subjects. Substances reacting at a rate of 2% or higher included jasmine absolute, geranium oil bourbon, l-citronellol, spearmint oil, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta-γ-2-benzopyran, omega-6-hexadecenlactone, dimethyltetrahydrobenzaldehyde (isomer mixture), and α-amylcinnamaldehyde. These chemicals should be furthur evaluated to corroborate their allergenicity. We are constantly looking for new fragrance allergens to extend the diagnostic capability of the fragrance mix (FM).

    Notes: Transepidermal water loss (TEWL), capacitance, pH, blood flow and color reflectance were evaluated for quantifying the irritant response of vulvar and forearm skin to 3% sodium lauryl sulfate in 9 healthy premenopausal women. TEWL, capacitance, pH, blood flow, and all parameters of color reflectance changed significantly in forearm irritant dermatitis. In vulvar irritant dermatitis, however, significant changes were observed only for blond flow and the color reflectance parameters a* and b*. Using the combination of TEWL, capacitance and blood flow, forearm irritant dermatitis was detected with a sensitivity of 84% and a specificity of 100%. In this study, the best combination of parameters to detect vulvar irritant dermatitis was pH, blood flow. a* and b*, which had a sensitivity of 78% and a specificity of 75%. It is concluded that available bioengineering techniques are less suitable to quantify irritant dermatitis in the vulva than in the forearm.

    Notes: The present study, as part of PROMETES (Swiss Prospective Metal Worker Eczema Study), was performed to examine risk factors for the development of occupational hand dermatitis in metalworker trainees. Since this disease is very common, a high standard of preventive measures is necessary, especially for persons with an endogenous disposition for the development of eczema, e.g., atopics. Within the cohort of 201 healthy young men, 47 (23%) showed at least mild signs of hand eczema at 1 point of the 2.5 year observation period. Various occupational and domestic exposures, skin protection behaviour, regeneration time, and smoking habits, as well as atopic disposition, were studied with regard to their influence on the skin condition of the metalworker trainees. By multivariate analysis, we determined 3 important risk factors for the development of hand eczema in the cohort. (i) We showed once more the important influence of an atopic disposition as a major risk factor for occupational contact dermatitis. (ii) Furthermore, the results suggest that, apart from chemical irritants, mechanical factors should not be underestimated in their role as irritants to the epidermal barrier. (iii) Additionally, an insufficient amount of skin recovery time seems to support a cumulative sub-irritant effect on the skin, which may lead to irritant contact dermatitis.

    Notes: Products intended for individuals in contact with strongly adhering dirt often contain grit. Various clinical test methods have been developed for evaluating the potential of personal washing products to induce skin irritation. In the present study, differences in the irritant effects of washing products containing naturally-derived grit and synthetic grit were investigated in a forearm wash test. The forearms of 16 test subjects were washed in a total of 18 treatments (4 per day for 4 days, with 2 treatments on the 5th day). Treatment consisted of continuous washing for 2 min by a technician, who gently slid his fingertips with the lather up and down the forearm. Non-invasive instrumental measurements of skin barrier function were performed. Repetitive washing for 1 week lead to increased TEWL values, skin redness and decreased stratum corneum hydration. Results indicate differences in irritancy potential due to different types of grit, their surface and concentration. It is concluded that the repeated wash test seems to be adequate for rating personal washing products that contain grit.

    Notes: Skin protection measures − barrier creams, protective gloves – and skin care are widely recommended for the prevention of occupational hand dermatitis (HD) in skin risk professions, but there is hardly anything known about uptake levels of the measures. The objective of this controlled intervention study was to quantify the uptake and maintenance of skin protection and skin care measures in first-year bakers' apprentices. A total of 94 first-year bakers' apprentices were included in the study in September 2000. The apprentices were assigned to the skin protection and control group class-wise to reduce contamination. The skin protection group comprised 39 apprentices who were trained in skin protection measures at the beginning and after 4 weeks of training. 55 apprentices were assigned to the control group representing no skin protection intervention. Standardized interviews took place at the beginning of the training and at 4 monthly follow-ups (FU). The uptake of skin protection measures differed significantly between the groups (barrier cream p 〈 0.0001, protective gloves p = 0.046, skin care p = 0.025). Barrier cream use in the skin protection group was incorporated in the daily routine very well from the start and reached 100% at the end of the examination period (4th FU). At this time, only 3.2% of the controls used barrier creams. The level of acceptance of protective gloves (4th FU: skin protection group 43.3%; controls 32.3%) was considerably lower than that of barrier creams. The initial level of regular skin care was high in both groups (skin protection group 67.6%, controls 61.7%). After the intervention the acceptance of skin care rose to 88.9% in the skin protection group compared to 68.1% in the controls (4th FU). The present study has shown that skin protection and skin care measures can be introduced successfully in the daily routine of a skin risk occupation and high uptake and maintenance rates can be achieved.

    Notes: Melanoma and nonmelanoma skin cancers are among the most prevalent cancers in the human population. Solar ultraviolet radiation is considered a major etiological factor but the relationship between dose, timing, and nature of exposure to tumor development is still unclear. Free radicals are generated by normal physiologic processes, including aerobic metabolism and inflammatory response, but may inflict cellular damage when generation is increased and antioxidant defense mechanisms are overwhelmed. Important findings supporting the free radical hypothesis in skin carcinogenesis are: (1) Reactive oxygen species (ROS) are generated in UVA- and UVB-irradiated skin in excessive doses, (2) the natural cutaneous antioxidant defense is impaired upon UV-exposure, (3) free radicals are involved in all steps of carcinogenesis, (4) supplementation with antioxidants can inhibit skin carcinogenesis, and (5) conditions that increase ROS generation enhance photocarcinogenesis. These findings provide a promising rationale for the development of powerful new antioxidant strategies in the prevention and therapy of skin cancer.
