“…The prevalence of sensitization in the total population was calculated to be 2.02% [ 23 ], while male WhC prevalence was 0.71%, much lower than that reported from other studies and in particular 4.8% [ 24 ]. Also, thiuram mix 1% was uniquely positive in BlC males and BlC females which is in agreement with previous studies for workers (BlC) [ 7 , 25 , 26 ]. Finally, paraphenylenediamine 1% was uniquely positive in BlC females, BlC males, and WhC females.…”

Contact dermatitis is a frequent skin disorder related to environmental and occupational etiological factors, which could potentially affect all age groups, as well as both genders. The current study is aimed at exploring the patterns of contact sensitization with respect to the population’s occupational patterns in Greece. A retrospective analysis was performed in a cohort of 1978 patients from 2014 to 2016. Patients were divided into two categories; blue collars (BlC) and white collars (WhC), as well as detailed occupation was considered. Separation was performed on the basis of their profession, i.e., labor workers and handicraftsmen were sorted to the BlC group, while office employees were sorted to the WhC group. The common allergen in all occupational subgroups was nickel sulphate. The three most prevalent allergens in both BlC and WhC were nickel sulphate 5%, fragrance mix (I) 8%, and Balsam of Peru 25%. WhC males were uniquely sensitized to colophony 20% and formaldehyde 2%, and WhC females were uniquely sensitized to 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and neomycin sulphate 20%. Sensitization to allergens manifested occupation-specific patterns. Allergic contact dermatitis surveillance is of great importance towards the clinical and systematic understanding of the disease, especially with respect to the patient’s occupational profile.

There are several xenobiotics (allergens) in the environment which may induce allergic contact dermatitis (ACD), an occupational and environmental health disease. This health disease is of global concern because it has no cure and can only be managed in affected individuals by preventing them from further exposure to these allergens. The following quinones (Q) are known to be air pollutants: 1,2‐naphthoquinone (1,2‐NQ), 1,4‐naphthoquinone (1,4‐NQ), 9,10‐phenanthraquinone (PQ), and 9,10‐anthraquinone (AQ). There have been studies on the cytotoxicity of these air pollutants, but no kinetic studies have been carried out on them to determine their chemical reactivity and, more especially, their interaction with model proteins so as to ascertain if they can react with skin proteins thereby causing allergic reactions. This article provides details on the kinetics studies carried out on the protein‐haptenation reactions of these quinones with 4‐nitrobenzenethiol (NBT), a model nucleophile, as well as the mechanisms of their reactions. The NBT−Q reactions were investigated under pseudo‐first‐order conditions at various concentration ratios at a temperature of 25 °C at three different pH values by either ultraviolet‐visible (UV‐Vis) or stopped‐flow spectrophotometry, as appropriate. The reaction rate constants obtained for the NBT−Q reactions were in the following order: at pH 7.42: 1,2‐NQ>1,4‐NQ>PQ>AQ while at pH 5.65, the order was observed to be 1,2‐NQ>1,4‐NQ>PQ>AQ and at pH 8.41, it was 1,4‐NQ>PQ>AQ>1,2‐NQ. These trends for the reaction rate constants of the Q at the three pH values can be attributed to inductive effects and the position of oxo‐groups on the phenyl rings. The NBT−Q reactions were further investigated by determining the effect of ionic strength on the reaction rate constants with potassium sulphate as the background electrolyte. Our findings showed that there are no charged species at the transition state of the NBT−Q reactions. The products of the NBT−Q reactions were isolated and characterized by means of UV‐Vis and FTIR spectrophotometry and NMR and TOF‐MS spectrometry. The deduced mechanisms for the NBT−Q reactions were validated by computer simulation with “Simkine3” software.

Objectives: The aim of this study has been to evaluate the rate of contact sensitization to some rubber allergens and to bisphenol A (BPA) amongst students of dental medicine and dental patients. Material and Methods: A total of 50 participants were included in the study: 40 students of dental medicine exposed to the studied rubber allergens and BPA-based dental materials during the course of their education; 10 dental patients without occupational exposure to the latter substances served as a control group. All of them were patch-tested with the studied rubber allergens and bisphenol A. Results: Highest was the sensitizing action of carba mix, followed by benzoyl peroxide and mercapto mix. The sensitization rate for carba mix was significantly higher for dental students as well as for the whole studied population, if compared to the one for thiuram mix (Chi 2 = 12.9, p < 0.001; Chi 2 = 13.9, p < 0.001), bisphenol A (Chi 2 = 8.9, p < 0.001; Chi 2 = 11.9, p < 0.001), toluenesulfonamide formaldehyde resin (Chi 2 = 10.7, p < 0.001; Chi 2 = 13.9, p < 0.001) and benzoyl peroxide (Chi 2 = 4.7, p = 0.03; Chi 2 = 5.8, p = 0.016), and for dental patients, if compared to the one for mercapto mix (Chi 2 = 7.07, p = 0.008). Concomitant positive skin patch-test reactions to carba mix and to benzoyl peroxide, and to all the studied allergens were established. Conclusions: Carba mix could be outlined as a sensitizer of paramount importance for dental students as well as for dental patients. Benzoyl peroxide was the second ranked sensitizer for dental students. Positive skin patch-test reactions to bisphenol A and toluenesulfonamide formaldehyde resin were established only among the group of dental students.
