Objectives: Manicurists are exposed to various chemicals in nail and skin care products and may develop ocular, nasal, respiratory or skin adverse reactions to them. To investigate the occurrence of ocular, nasal, respiratory and skin problems among manicurists and to identify their causal factors, particularly allergic etiology and occupational origin.Material and Methods: Manicurists employed in beauty salons in the central region of Poland were invited to fill in the questionnaire and undergo medical examination, skin prick tests with common aeroallergens, patch tests with European Baseline Series and (Meth)Acrylates Series-Nails and spirometry.Results: In the questionnaire adverse nasal symptoms were reported by 70%, ocular - by 58%, respiratory - by 42%, hand eczema - by 43% of manicurists. In the medical interview, the frequency of those complaints was lower: nasal ones - 41%, ocular - 24%, cough - 18%, hand skin dryness - 20%, hand eczema - 6%. Cough and hand skin dryness occurred significantly more frequently than in the case of controls. Contact allergy was found for 41% of manicurists and 35% of controls. The prevalence of nickel sensitization was high in both groups (38% and 27%, respectively). Only 3 manicurists reacted to (meth)acrylates. The frequency of atopic diseases was similar in compared groups. Irritant nasal and respiratory reactions were significantly more prevalent among manicurists (nasal - 18% vs. 2%, p < 0.01; respiratory - 18% vs. 1%, p < 0.001). Work-related nasal irritant reactions were finally diagnosed for 19%, ocular ones - for 13%, respiratory - for 18% and within hand skin - for 23% of manicurists.Conclusions: The frequency of workattributed irritant mucosal and skin symptoms among manicurists is high. Exposure to acrylates is an important source of mucosal irritant reactions while occlusive gloves cause irritation of hand skin. The prevalence of nickel allergy among Polish females is high.

Background: Nurses are prone to develop hand eczema due to occupational exposure to irritants, including wet work. The aim of the study was to evaluate the impact of wet work on selected skin properties, reflecting epidermal barrier function--transepidermal water loss (TEWL) and stratum corneum hydration--and additionally skin viscoelasticity, in nurses., Material and Methods: Study subjects included 90 nurses employed in hospital wards. Measurements were carried out within the dorsal aspect of the dominant hand, using a Cutometer MPA 580 equipped with Tewameter TM 300 and Corneometer CM 825 (Courage & Khazaka, Germany) probes. Examina- tions took place on hospital premises. Similar measurements were performed in the control group of females non-exposed to irritants., Results: In the examined group of nurses, mean TEWL was 15.5 g/h/m2 and was higher than in the control group (12.99 g/h/m2). After rejecting the extreme results, the difference between the groups proved to be statistically significant (p < 0.05). The mean value of stratum corneum hydration was lower in the examined group (37.915) compared with the control group (40.05), but the difference was not sta tistically significant. Also results of viscoelasticity assessment showed no significant differences between studied groups., Conclusions: The results of the assessment of skin biophysical properties show that wet work exerts a moderately adverse impact on skin condition. A higher TEWL value and a lower stratum corneum hydration in workers exposed to irritants reflect an adverse impact of these factors on the epidermal barrier function.
