“…As reported in our previous study on dental workers, their clinical pictures were mostly erythema and dryness (66%), while localizations were predominantly on the hands and fingers (96%) [16]. According to the study by Minamoto et al [12], 46.4% of dental workers reported a lifetime history of chronic hand eczema, which was commonly related to a history of AD, asthma/allergic rhinitis, dry skin, shorter duration of work, and hand washing (> 10 times/day). Our results were somewhat similar and indicated peak lesion incidence at the beginning and end of a professional career.…”

“…According to the patch test results of Schwensen et al [22] (thiuram mix, mercaptobenzothiazole, mercapto mix), this contact allergy was found in 3.1% (often to thiuram mix) and was significantly associated with occupational CD, hand and facial dermatitis, and age (> 40 years). According to the patch testing of dental workers by Minamoto et al [12], the most frequent occupationally relevant contact allergens were rubber chemicals and acrylates. Because of the limited conditions of our field study and its implementation, we did not research other common allergens in today's dental work environment (acrylates and methacrylates used in dental prostheses, dental restoration materials, antiseptic agents, and disinfectants, etc.…”

“…Often overlooked is nonallergic CD (irritant or toxic), common in healthcare workers due to frequent hand washing, glove changes, harsh soaps, disinfectants, detergents, etc. [5,7,11,12]. Other factors can also contribute to the onset of irritant CD -perspiration from glove occlusion or prolonged contact with an alkaline, skin sensitivity, prior skin damage, or an atopy such as atopic dermatitis (AD) [13].…”

Background: Dental workers often experience unwanted allergic and nonallergic skin reactions resulting in different contact dermatoses (e.g., contact urticaria, irritant and allergic contact dermatitis) that are often attributed to rubber gloves. Objective: To examine allergic and nonallergic contact dermatoses by different methods amongst dental professionals and dental students, more specifically, reactions to natural rubber latex (NRL), rubber additives, and other causative factors. Methods: In this cross-sectional study we surveyed a total of 444 subjects (dentists, assistants, technicians, and students); 200 agreed to be tested to latex by the standard skin prick test (SPT) and prick-by-prick test, of whom 107 were patch tested to rubber additives (mercapto mix, thiuram mix, carba mix, and N-isopropyl-N-phenyl-4-phenylenediamine [IPPD]). Results: Skin lesions appeared significantly more frequently with longer work experience (p = 0.002; V = 0.181), frequent glove changes (p < 0.001; V = 0.310), and hand washing (p < 0.001; V = 0.263), and in subjects with a history of allergies (atopic dermatitis, allergic rhinitis, allergic conjunctivitis, and others) (p < 0.001; V = 0.183). Positive SPTs to latex occurred in 14/200 subjects (7%), of whom 5/14 subjects (35.7%) were also positive in prick-by-prick tests. Patch tests were positive in 5/104 subjects (4.8%) (mercapto mix 1%, thiuram mix 1.9%, and carba mix 1.9%). Conclusion: Only a small number of our subjects were allergic to latex (7%) or rubber additives (4.8%). Thus, self-reported contact dermatoses (during NRL product use) in dental professionals and students are not commonly caused by allergies to latex and rubber additives, as is often assumed, but by other factors.

“…In contrast to the present results, previous studies showed a significant difference in atopic dermatitis, allergic conjunctivitis, asthma, and childhood eczema. [30] Another study reported that atopic history played a role in the development of dermatitis in work setting. [31] Consistent with the present results, another study reported an insignificant correlation between hand eczema and asthma or childhood eczema in car mechanics.…”

Little is known about the epidemiology of contact dermatitis (CD) in the Chinese clothing industry. This study aimed to investigate the prevalence and some risk factors of contact dermatitis among clothing manufacturing employees in Beijing.This cross-sectional study was conducted by interview using self-administered questionnaires and skin examination between May and August in 2016. Five-hundred twenty-nine employees who had worked at sewing, ironing, and as managers at 12 clothing manufacturing factories were studied.The overall 1-year prevalence of CD among the clothing employees was 28.5% (151/529 employees), with significantly higher prevalence among ironing workers (50%) and sewers (31.7%) compared with managers (12.7%; P < 0.001, n = 529). A significant association was noticed between the 1-year prevalence of CD and types of occupation (sewers and ironing workers versus managers, respectively), exposure to garment materials (leather and feather), dry skin, allergic rhinitis, age, and smoking.Among employees in Chinese clothing industry, sewers and ironing workers had a higher 1-year prevalence of CD than managers. It is noteworthy that exposure to leather and feather materials and the types of manual work are associated with CD, as well as dry skin and allergic rhinitis.

“…HE is often work‐related, with a high prevalence especially in occupations involving wet work, such as nursing, medical and service work . In Japan, three population‐based studies have been performed . The 1‐year prevalence of HE in those Japanese studies, which were performed in an occupational setting, was reported to be much higher than the estimated prevalence of 10% found in the general population .…”

Hand eczema (HE) is a common skin disease that impairs health‐related quality of life (HRQOL). Impairments in HRQOL have already been reported in Japanese HE patients using the Skindex‐16. Recently, an instrument to measure disease‐specific HRQOL in HE patients was developed by an international expert group, consisting of domains for: (i) symptoms; (ii) emotions; (iii) functioning; and (iv) treatment and prevention. The objective of this study is to translate the English‐language version of the Quality of Life Hand Eczema Questionnaire (QOLHEQ) to Japanese and then to validate the Japanese version. The Japanese version of the QOLHEQ, the Dermatological Life Quality Index (DLQI) and a questionnaire regarding basic demographic information, including patient ratings of HE severity, were distributed to Japanese HE patients. Additionally, a dermatologist evaluated patients’ HE severity using the Physician Global Assessment. A total of 124 patients with a mean age of 43.7 years were included in the analysis, and 78% of the sample was female. Cronbach's alphas for the domains symptoms, emotions, functioning, and treatment and prevention were 0.76, 0.89, 0.88 and 0.81, respectively. The total QOLHEQ score showed a strong correlation with the DLQI, a moderate correlation with patient‐rated severity and weak correlations with dermatologist‐rated severity and the number of consultations. The Japanese version of the QOLHEQ showed excellent reliability and high validity. The Japanese version of the QOLHEQ is ready for use in epidemiological studies to evaluate HRQOL impairments in HE patients.
