Николай! Больше информации о пастах Radonta, чем на сайтеwww.gloryon.com мы не имеем. А подборку свежих статей о негативном действии SLS сделал: 1. Simultaneous sodium lauryl sulphate testing improves the diagnostic validity of allergic patch tests. Results from a prospective multicentre study of the German Contact Dermatitis Research Group (Deutsche Kontaktallergie-Gruppe, DKG). Loffler H, Becker D, Brasch J, Geier J; The German Contact Dermatitis Research Group (DKG). Department of Dermatology, University of Mainz, Mainz, Germany. harald. loeffler@mailer. uni-marburg. deBACKGROUND: There is evidence that a higher skin susceptibility may induce nonspecific erythematous or weak positive reactions to contact allergens in patch testing. OBJECTIVES: To evaluate whether simultaneous application of sodium lauryl sulphate (SLS) along with diagnostic patch tests with contact allergens can provide information regarding skin irritability which may help to discriminate allergic from nonspecific irritant reactions to contact allergens. METHODS: Between July 2001 and June 2003, this prospective study collected patch test data of 5971 patients from 19 centres in Germany and Austria in the Information Network of Departments of Dermatology (IVDK). In addition to contact allergens (standard series and eight known \'problematic\' allergens with a low reaction index and a high positivity ratio: 1,3-diphenylguanidine, amerchol L-101, benzalkonium chloride, benzoyl peroxide, cocamidopropyl betaine, octyl gallate, phenyl mercuric acetate and propylene glycol), patches with SLS 0.5% and 0.25% aq. were applied. Reactions to the allergens and to SLS were analysed at the IVDK data centre. The association between an erythematous or positive reaction to a certain allergen and an irritant reaction to SLS was assessed with logistic regression analysis, at the same time controlling for the influence of age and sex. RESULTS: Of the 29 allergens of the standard series,23 and 21 gave a higher percentage of nonspecific erythematous reactions in patients with an irritant reaction to 0.25% and 0.5% SLS, respectively, in comparison with SLS-negative patients. All eight \'problematic\' allergens gave an increased percentage of nonspecific erythematous reactions. Similarly,22 and 21 allergens of the standard series gave a higher percentage of positive allergic reactions in patients with an irritant reaction to 0.25% and 0.5% SLS, respectively, and seven of the eight \'problematic\' allergens gave a higher percentage of positive allergic reactions (exception: octyl gallate). For most allergens, the markers of skin reaction (reaction index and positivity ratio) were worse in SLS-positive patients. Differences were more pronounced when testing with SLS 0.25% than with SLS 0.5%. CONCLUSIONS: Because there is a convincing association between skin irritability (evaluated by SLS test) and the degree of skin reaction to contact allergens, the SLS test may help in deciding whether a doubtful erythematous or weakly \'positive\' skin reaction should be interpreted as allergic or irritant.2. Objective interpretation of severity of SLS induced edema by stereoimaging. Kim MG, Park SY, Ha SH, Lee JD, Hong SH, Moon JS, Oh CH. Department of Electric and Information Engineering, Korea University, Chungnam, Republic of Korea. BACKGROUND: In the evaluation of the severity of skin inflammations, visual scoring system is widely being used as a subjective method. However, it is well known that interobserver variations occur even between the interpretations of experienced dermatologists. OBJECTIVE: To develop a new objective and quantitative method for the evaluation of skin surface contours and for the assessment of severity in SLS-induced edema, a new investigatory tool based on the concept of "stereoimaging" was studied. Differences between binocular images were used by a stereoimage optical topometer (SOT) system capable of calculating skin surface topographic information, which was then used to produce a three-dimensional image. METHODS: We compared the results obtained by SOT with a visual scoring system after applying sodium lauryl sulfate (SLS) to skin. The degree of edema was assessed qualitatively by visual scoring (0: none,1: mild edema,2: moderate edema,3: severe edema). To quantify the severity, five three-dimensional parameters (S (a), S (z), SL, SA and SV) were used in the SOT analysis. RESULTS: The means of these five parameters increased significantly in visual grade 1+ compared to visual grade 0 and the means of the five parameters decreased significantly and proportionally as the visual grades increased from 1+ to 3+. A highly significant correlation was found to exist between the visual scoring results and the five SOT parameters. CONCLUSION: SOT can be used to evaluate the severity of SLS-induced edema objectively and can be extensively applied to evaluate the degree of severity in other inflammatory skin conditions.3. Patch testing with the irritant sodium lauryl sulfate (SLS) is useful in interpreting weak reactions to contact allergens as allergic or irritant. Geier J, Uter W, Pirker C, Frosch PJ. Information Network of Departments of Dermatology (IVDK), Georg August University, Department of Dermatology, Gottingen, Germany. jgeier@med. uni-goettingen. deSeveral contact allergens are tested at concentrations which might cause irritant reactions. In this study we investigated whether the reactivity to a standard irritant is useful in identifying subjects with hyperreactive skin yielding a higher rate of doubtful or irritant reactions. Sodium lauryl sulfate (SLS) 0.5% (aqua) was tested in addition to the standard series routinely for 5 years in the Department of Dermatology, Dortmund. For data analysis, we compared reactions at D3 to the standard series, the vehicle/emulsifier and preservative series and benzoyl peroxide to the reactions obtained with SLS. Proportions were standardized for age and sex. The association between reactivity to a certain allergen and SLS reactivity as a dichotomous outcome, controlled for age and sex as potential confounders, was assessed with logistic regression analysis. Results showed that of the 1600 tested patients,668 (41.8%) had an irritant reaction to SLS which exceeded 2 + in only 41 patients. Seasonal variation was statistically significant, showing reduced SLS reactivity in summer vs. winter. Patients with irritant reactions to SLS showed significantly more erythematous reactions to the following 10 allergens of the standard series: fragrance mix, cobalt chloride, balsam of Peru (Myroxylon pereirae), lanolin alcohol,4-phenylenediamine base (PPD), propolis, formaldehyde, N-isopropyl-N\'-phenyl-p-phenylenediamine (IPPD), benzocaine, and 4-tert-butylphenol-formaldehyde resin. No significant differences regarding strong positive allergic reactions were observed. Concerning other allergens, significantly more erythematous reactions were observed in SLS-reactive patients to benzoyl peroxide, octyl gallate, cocamidopropyl betaine, Amerchol L-101, tert-butylhydroquinone, and triethanolamine. In the SLS-reactive group of patients, the reaction index was negative for 10 allergens of the standard series compared to only 5 in the SLS non-responder group. For the first time, this study, based on a large data pool, revealed a significant association between reactivity to the irritant SLS and erythematous reactions to certain allergens. With SLS as a marker for hyperreactive skin at hand, some of these reactions can now be classified as irritant more confidently, particularly if there is no history of exposure to the allergen.4. Allergic contact dermatitis to detergents: a multicenter study to assess prevalence. Belsito DV, Fransway AF, Fowler JF Jr, Sherertz EF, Maibach HI, Mark JG Jr, Mathias CG, Rietschel RL, Storrs FJ, Nethercott JR. Division of Dermatology, University of Kansas Medical Center, Kansas City, KS 66160-7319, USA. BACKGROUND: Allergic contact dermatitis (ACD) to optical brighteners and enzymes in laundry detergents was the focus of numerous reports in the early 1970s. Subsequently, there has been little published on the incidence of allergic reactions to chemicals in laundry detergents. Nonetheless, consumers and physicians continue to ascribe allergic contact reactions to laundry detergents. OBJECTIVE: This article reports the findings of a multicenter study on the prevalence of patch test reactions to a liquid and a granular laundry detergent provided by Procter & Gamble Company (Cincinnati, Ohio). METHODS: Patients referred to members of the North American Contact Dermatitis Group for evaluation of potential ACD were invited to participate in the study, which involved the placement of 2 patch tests (a 0.1% aqueous dilution of a granular laundry detergent and a 0.1% aqueous dilution of a liquid laundry detergent). Whether the patients had atopic dermatitis and whether they or their physicians felt that their dermatitis might be related to laundry detergents were noted. Reactions to the laundry detergents were correlated with allergic reactions to the following screening chemicals: fragrances, nickel, and potassium dichromate. Patients who experienced a reaction to at least one of the laundry detergents could enter phase II of the study, which involved testing to varying dilutions of the laundry detergents, to 0.1% sodium lauryl sulfate (as an irritant control), and to laundered patches of cotton. Patients positive in phase II could enter phase III, which involved wearing a garment laundered with the detergent. Phases II and III were double blinded. RESULTS: Of the 3120 patients seen by members of the North American Contact Dermatitis Group during the 2 years of this study,738 patients volunteered to enroll. Enrollment was not statistically randomized. Of these 738,5 (0.7%) had positive patch test reactions to granular laundry detergent (0.1%, aqueous) ; 3 of these 5 also had positive reactions to the liquid laundry detergent (0.1%, aqueous). In 4 of the 5 patients, the reaction to detergent was thought to have present relevance to their dermatitis; in 1 of the 5, the reaction was deemed to have past relevance. One of these 5 patients had allergy to fragrances. None of the patients was positive to nickel or chromate. Two of the 5 entered phases II and III. Of these 2 patients,1 had essentially negative repeat dilutional patch testing and "use testing" suggesting that the earlier reaction patterns may have been irritant. The remaining patient had positive dilutional reactions to both the liquid and granular laundry detergent; however, she also had a positive reaction to sodium lauryl sulfate and to a swatch from a T-shirt laundered without detergent. Upon "use testing" in phase III, this latter patient experienced diffuse dermatitis under both the half of the T-shirt laundered with detergent and that laundered without detergent. CONCLUSION: Laundry detergents appear to be a rare cause of ACD. Among 738 patients with dermatitis,5 (0.7%) reacted to a 0.1% aqueous dilution of a laundry detergent. Only 2 of these 5 patients could be evaluated in greater detail to differentiate allergic from irritant patch test reactions to detergents. Upon further testing in 2 patients, the reaction in 1 of 2 could not be reduplicated and the reaction in the other was invoked both by the detergents and the controls. Thus, whether our study patients were truly allergic and, if so, what the allergenic material (s) in detergents might be, remains unknown. Therefore the reported incidence rate for detergent-induced allergy of 0.7% in dermatitic patients may be too high, possibly because of false-positive irritant reactions.
