[Ab] Resumo:BACKGROUND: Allergic contact dermatitis after exposure to p-phenylenediamine (PPD)-containing hair dye products is a common and important clinical problem. Because there is a high rate of cross-elicitation of allergic contact dermatitis to other important hair dye products (such as p-toluene diamine and other aminophenol hair dyes) in PPD-allergic patients, safer alternative dyes with excellent hair coloring options are needed. OBJECTIVE: This study aimed to study tolerance to Me-PPD in a PPD-allergic cohort. METHODS: Twenty ethnically diverse volunteers with a history of contact dermatitis to hair dyes or other PPD-containing chemicals and positive patch test results to 1% PPD in petrolatum were recruited to study their immediate and delayed skin reactivity to PPD, vehicle control, and 2-methoxy-methyl-PPD (Me-PPD) using the allergy alert test (simulating hair dyeing conditions) on volar forearm skin. This test is a short-contact open patch test. CONCLUSIONS: The Me-PPD may offer a safer alternative for PPD-allergic patients with an absent or reduced elicitation response in the allergy alert test simulating hair dye use conditions. The absent or reduced response to Me-PPD diagnosed using the allergy alert test has been shown to help reduce the possibility of moderate to severe cross-elicitation reactions among consumers during hair dyeing.

[Ab] Resumo:BACKGROUND/AIM: Hair dye may contain mutagenic compounds which could be associated with an increased incidence of breast cancer in women who use it. The aim of this study was to examine the association between the personal use of hair dyes and the risk of breast cancer. MATERIALS AND METHODS: We conducted a literature review of epidemiological studies reporting breast cancer-specific risks among hair dye users versus non-users. The data for the incidence of breast cancer following the 'ever' use of hair dye in studies which met the inclusion criteria was analysed using a meta-analysis. The relative risk ratio (RR) and 95% confidence intervals (CI) were determined. RESULTS: A total of eight case-control studies published between 1980 and 2017 met the selection criteria and were included in the meta-analysis. Compared to non-users, using a random effects model and the Duval and Tweedie's trim and fill procedure to adjust for publication bias in the presence of between studies heterogeneity, the adjusted RR for women using hair dyes was 1.1885 (95% CI=1.03228-1.36835). This indicates an 18.8% increased risk of future development of breast cancer among hair dye users. CONCLUSION: Although further work is required to confirm our results and clarify potential mechanisms, our findings suggest that exposure to hair dyes may contribute to an increased breast cancer risk.

[Ab] Resumo:Chemical-induced depigmentation of the skin has been recognized for more than 75 years, first as an occupational hazard but then extending to those using household commercial products as common as hair dyes. Since their discovery, these chemicals have been used therapeutically in patients with severe vitiligo to depigment their remaining skin and improve their appearance. Because chemical-induced depigmentation is clinically and histologically indistinguishable from nonchemically induced vitiligo, and because these chemicals appear to induce melanocyte autoimmunity, this phenomenon should be known as "chemical-induced vitiligo," rather than less accurate terms that have been previously used.

[Ab] Resumo:BACKGROUND: Risk factors for B-cell non-Hodgkin lymphoma (B-NHL) have not been assessed among Palestinian Arabs (PA) and Israeli Jews (IJ). METHODS: In a case-control study we investigated self-reported medical and lifestyle exposures, reporting odds ratios (ORs) and 95% confidence intervals [CIs], by ethnicity, for overall B-NHL and subtypes. RESULTS: We recruited 823 cases and 808 healthy controls. Among 307 PA/516 IJ B-NHL cases (mean age at diagnosis = 51 [±17] versus 60 [±15] years, respectively) subtype distributions differed, with diffuse large B-cell lymphoma (DLBCL) being prominent among PA (71%) compared to IJ (41%); follicular lymphoma (FL), was observed in 14% versus 28%, and marginal zone lymphoma, in 2% versus 14%, respectively. Overall B-NHL in both populations was associated with recreational sun exposure OR = 1.43 [CI:1.07-1.91], black hair-dye use OR = 1.70 [CI:1.00-2.87], hospitalization for infection OR = 1.68 [CI:1.34-2.11], and first-degree relative with hematopoietic cancer, OR = 1.69 [CI:1.16-2.48]. An inverse association was noted with alcohol use, OR = 0.46 [CI:0.34-0.62]. Subtype-specific exposures included smoking (FL, OR = 1.46 [CI:1.01-2.11]) and >monthly indoor pesticide use (DLBCL, OR = 2.01 [CI:1.35-3.00]). Associations observed for overall B-NHL in PA only included: gardening OR = 1.93 [CI:1.39-2.70]; history of herpes, mononucleosis, rubella, blood transfusion (OR>2.5, P<0.01 for all); while for IJ risk factors included growing fruits and vegetables, OR = 1.87 [CI:1.11-3.15]; and self-reported autoimmune diseases, OR = 1.99 [CI:1.34-2.95]. CONCLUSIONS: In these geographically proximate populations we found some unique risk factors for B-NHL. Heterogeneity in the observed associations by ethnicity could reflect differences in lifestyle, medical systems, and reporting patterns, while variations by histology infer specific etiologic factors for lymphoma subtypes.

[Ab] Resumo:Hair dyes contain strong allergens and are widely available. Correct labelling is a necessity in order to provide information about the contents. To compare the labelling and content of hair dyes. In total, 52 hair dyes, from 11 different countries, were bought over the counter. High-pressure liquid chromatography was used for the analysis of p-phenylenediamine (PPD), toluene-2,5-diamine (2,5-TDA), and three oxidation products of PPD. There was good agreement between labelling and content, although seven of the 52 products (13.5%) studied were incorrectly labelled. There were differences in the geographical use of PPD and 2,5-TDA; 2,5-TDA was more common in European products, while PPD was more common in products purchased outside Europe and was present in higher concentrations. All dyes purchased in Europe contained PPD and 2,5-TDA at levels within the limits defined by European legislation, however, levels were higher in some products purchased outside Europe. Only a small group of hair dyes sold in Europe were mislabelled. Further improvement in labelling, by providing the concentration of chemicals, may facilitate products to be purchased both locally and within the global market, when travelling or on the internet.

[Ab] Resumo:A flexible and miniaturized metal semiconductor metal (MSM) biomolecular photodetector was developed as the core photocurrent system through chemiluminescence for hydrogen peroxide sensing. The flexible photocurrent sensing system was manufactured on a 30-µm-thick crystalline silicon chip by chemical etching process, which produced a flexible silicon chip. A surface texturization design on the flexible device enhanced the light-trapping effect and minimized reflectivity losses from the incident light. The model protein streptavidin bound to horseradish peroxidase (HRP) was successfully immobilized onto the sensor surface through high-affinity conjugation with biotin. The luminescence reaction occurred with luminol, hydrogen peroxide and HRP enzyme, and the emission of light from the catalytic reaction was detected by underlying flexible photodetector. The chemiluminescence in the miniaturized photocurrent sensing system was successfully used to determine the hydrogen peroxide concentration in real-time analyses. The hydrogen peroxide detection limit of the flexible MSM photodetector was 2.47mM. The performance of the flexible MSM photodetector maintained high stability under bending at various bending radii. Moreover, for concave bending, a significant improvement in detection signal intensity (14.5% enhancement compared with a flat configuration) was observed because of the increased photocurrent, which was attributed to enhancement of light trapping. Additionally, this detector was used to detect hydrogen peroxide concentrations in commercial hair dye products, which is a significant issue in the healthcare field. The development of this novel, flexible and miniaturized MSM biomolecular photodetector with excellent mechanical flexibility and high sensitivity demonstrates the applicability of this approach to future wearable sensor development efforts.

[Ab] Resumo:Para-phenylenediamine is widely used as a chemical in hair dyes and in combination with henna. This dye is used to paint the body for decorative reasons, to speed the processing time of henna and to intensify the results. Para-phenylenediamine is widely used in the Middle East, North Africa and India. Several reports have been published of the fatal ingestion of hair dye containing para-phenylenediamine. Here, we describe the case of a 14-year-old girl who ingested the compound but whose prompt treatment prevented her death. Ingestion of para-phenylenediamine produces a typical triad of angioneurotic oedema, rhabdomyolysis and acute tubular necrosis. Awareness of signs of these associated conditions in our patient, together with a comprehensive history, facilitated appropriate treatment to be instituted. We document the steps we took to enable her complete physical recovery.

[Ab] Resumo:BACKGROUND: Hairdressers are at risk of developing occupational contact dermatitis because of their intense contact with wet work in combination with chemicals. OBJECTIVES: To perform an analysis of a cohort study of hairdressers with occupational contact dermatitis recognized in the period 2006-2011, focusing on individual and environmental factors associated with the disease. METHODS: The study was a descriptive, register-based survey including all hairdressers with recognized occupational contact dermatitis in Denmark in the period January 2006 to September 2011. Data were obtained from the Danish National Board of Industrial Injuries. RESULTS: The study comprised 381 patients (373 women and 8 men). The median age was 25 years, 64.8% were apprentices, and 35.2% were fully trained hairdressers. The prevalence of atopic dermatitis was 36.0%, and was significantly higher among apprentices than among fully trained hairdressers (44.9% and 19.4%, respectively) (p < 0.001). Of the patients, 48.3% had their dermatitis recognized as occupational irritant contact dermatitis, 46.7% had their dermatitis recognized as as occupational allergic contact dermatitis or combined allergic and irritant contact dermatitis, and 5.0% were recognized as having occupational contact urticaria. CONCLUSION: The low median age, the high percentages of atopic dermatitis in apprentices and the fact that more apprentices than fully trained hairdressers had recognized occupational contact dermatitis underlines the importance of early prevention.

[Ab] Resumo:BACKGROUND: Cross-reactions and co-sensitizations are of great importance in understanding contact allergy and exposure sources. OBJECTIVES: To investigate common cross-reactions and co-sensitizations in p-phenylenediamine (PPD)-sensitized and toluene-2,5-diamine (TDA)-sensitized individuals. METHODS: From our patch test population, 8036 patients patch tested with the European baseline series were extracted. Readings had to be performed at least on day 3 according to ICDRG guidelines. RESULTS: Two hundred and fifty-one patients were sensitized to PPD and/or TDA; 231 patients were sensitized to PPD, and 109 to TDA. Significant differences were observed regarding the strengths of patch test reactions to PPD and number of cross-reactions. For TDA, a difference was found between all reaction strengths, except between + and ++ strengths. PPD-sensitized individuals were more likely to be sensitized to carba mix, cobalt chloride, colophonium, p-tert-butyl phenolformaldehyde resin, paraben mix, and methylisothiazolinone. TDA-sensitized individuals were more often sensitized to carba mix. CONCLUSIONS: Cross-reactivity was commonly found among individuals sensitized to PPD or TDA, and was strongly related to the strength of the patch test reaction. Regarding co-sensitizations, a frequently appearing or common exposure source could not be determined. However, modification of the allergen by, for example, the skin microbiota may have caused the formation of molecules that are, for the human immune system, indistinguishable from PPD.

However, the dyeing process takes a long time to complete compared to commercial hair-dyeing products. To overcome this bottleneck, pre-synthesized polymeric products of the oxidative reaction of Trametes versicolor laccase on catechin and catechol, either with or without mordant agents (e.g., FeSO4), were here employed to achieve permanent keratin hair dyeing in various colors and shades. The laccase action in acidic sodium acetate buffer led to a deep black coloration after coupling reactions between the plant phenols. The colored dye products were then desalted and concentrated with ultrafiltration. The dyes, with or without mordant agents, caused a significant increase in ΔE values (i.e., color difference value) in gray human hair within 2.5 hours. In addition, different keratin colors and shades were induced depending upon the mordanting and pH changes. The dyed hair also exhibited a strong resistance to detergent treatments, indicating that our methods can give rise to permanent hair dyeing. Overall, our work has provided novel insight into developing eco-friendly hair-dyeing methods as alternatives to commercial toxic diamine-based dyes.
