Protection during production: Problems due to prevention? Nail and skin condition after prolonged wearing of occlusive gloves

Evaluation of Skin Barrier Condition Among Physicians and Dentists

Background: Physicians and dentists are at risk for chronic hand eczema, but their skin barrier condition has rarely been investigated before. Objective: To objectively assess the skin barrier condition among physicians and dentists. Methods: This cross-sectional epidemiological study included an occupational questionnaire, medical examination of hand skin, skin transepidermal water loss (TEWL), and pH measurements, analyzed in 5 groups (N = 37 in each): physicians-nonsurgeons, physicians-surgeons, dentists-nonsurgeons, dentists-surgeons, and control group (unexposed workers). Results: Critical skin condition (TEWL >30 g/[m2·h]) was found in 14% of control workers, 14% physicians nonsurgeons, 22% physicians surgeons, 27% dentists nonsurgeons, and 43% dentists surgeons. The latter had the worst stratum corneum condition indicated by a TEWL median of 25.80 g/(m2·h) (interquartile range [IQR] 19.24-34.31). Hand skin pH was highest among dentists with nonsurgical specializations, with a median of 5.33 (IQR 5.15-5.60), where 38% of them had pH >5.5. Male sex (P < 0.001) and glove use for >1 h/day (P = 0.009) were associated with elevated hand TEWL values, whereas female sex (P < 0.001) and glove use for >4 h/day with elevated pH values (P < 0.001). Conclusions: Prolonged glove usage and dental profession, especially surgical work, significantly affect the skin barrier condition. This study was the first to objectively determine skin barrier condition among dentists and physicians.

Causes of irritant contact dermatitis after occupational skin exposure: a systematic review

PURPOSE

Irritant contact dermatitis (ICD) is a major cause of occupational disease. The aim was to review the relation between exposure to occupational irritants and ICD and the prognosis of ICD.

METHODS

Through a systematic search, 1516 titles were identified, and 48 studies were included in the systematic review.

RESULTS

We found that the evidence for an association between ICD and occupational irritants was strong for wet work, moderate for detergents and non-alcoholic disinfectants, and strong for a combination. The highest quality studies provided limited evidence for an association with use of occlusive gloves without other exposures and moderate evidence with simultaneous exposure to other wet work irritants. The evidence for an association between minor ICD and exposure to metalworking fluids was moderate. Regarding mechanical exposures, the literature was scarce and the evidence limited. We found that the prognosis for complete healing of ICD is poor, but improves after decrease of exposure through change of occupation or work tasks. There was no substantial evidence for an influence of gender, age, or household exposures. Inclusion of atopic dermatitis in the analysis did not alter the risk of ICD. Studies were at risk of bias, mainly due to selection and misclassification of exposure and outcome. This may have attenuated the results.

CONCLUSION

This review reports strong evidence for an association between ICD and a combination of exposure to wet work and non-alcoholic disinfectants, moderate for metalworking fluids, limited for mechanical and glove exposure, and a strong evidence for a poor prognosis of ICD.

Hygienic and cosmetic care habits in polish women during COVID-19 pandemic

Background

COVID‐19 pandemic influences a lot of aspects of human life. Particularly, hygienic habits are affected.

Objectives

Changes in washing and cosmetic standards during the pandemic toward the past are in the focus of our interest.

Material and Methods

The questionnaire study was conducted anonymously in 140 women. The examination concerned pre‐ and during‐pandemic routine hygiene activities such as hands washing, hair washing, bathing, the use of disinfectants, and use of specific type of cosmetics.

Results and Discussion

Compared were data before and during pandemic. Responders declared increased handwashing and taking shower after coming back home and after using local city transportation. We found also that increased use of disinfectants during COVID‐19 pandemic. In contrary to that, number of people washing their hair decreased slightly. Work documents that profile of used cosmetics was changed; increasing hand cream use and decreasing in makeup cosmetics. Nearly, half of the respondents declare that they will maintain new habits also after the pandemic has ended.

Pathogenesis, Clinical Signs and Treatment Recommendations in Brittle Nails: A Review

Nail plate brittleness (or fragility) is a common complaint affecting up to 20% of the population, especially women over 50 years of age, with fingernail fragility being more prevalent than toenail fragility. Nail brittleness is characterized by nails that split, flake and crumble, become soft and lose elasticity. The main clinical presentations are: onychoschizia, onychorrhexis, superficial granulation of keratin and worn-down nails. According to causative factors, we can distinguish 2 forms of nail fragility (NF): a primary "idiopathic or brittle nail syndrome" form and NF secondary to different causes such as inflammatory nail disorders, infections, systemic diseases and general conditions, traumas and alteration of the nail hydration. Optimal management requires treatment of the primary cause of brittle nails, when possible. In idiopathic NF oral supplementation, vitamins (especially biotin, also known as vitamin B7), trace elements and amino acids (especially cysteine) have been reported to be useful. In addition, several products, such as topical moisturizers and lacquers could be considered to restructure the affected nail plate and to reduce psychological impacts of this common problem.

The tissue viability imaging system-Suitable method for discovering minimal skin changes in occupational screenings? Results of a cross-sectional field study

BACKGROUND

For early detection of initial skin changes in occupational screenings, only few objective assessment systems are available.

OBJECTIVES

With the aim of assessing an objective measurement method for hand eczema, we trialed the application of the tissue viability imaging (TiVi) system, quantifying erythema non-invasively by polarized light spectroscopy.

MATERIALS AND METHODS

In a field study with 625 employees of a semiconductor production company, 411 were exposed to prolonged wearing of occlusive gloves in the clean room. TiVi system and Hand Eczema Score for Occupational Screenings (HEROS), a quantitative skin score for the hands, were used, supplemented by a standardized personal interview.

RESULTS

TiVi values of 65 up to 246 for each hand (palm or back), for each participant summed to overall 289 up to 848 (median 389), were measured. Higher TiVi values were noted for men, smokers, and with increasing age. Correlation between TiVi and HEROS was only weak. Several factors like skin pigmentation, thickness of the skin, or tattoos seem to influence TiVi results.

CONCLUSIONS

The practical relevance of one-time measurements with the TiVi system in occupational screenings seems to be limited. Specifically, the TiVi system cannot replace dermatological examinations at the workplace. Notwithstanding, the application for other scientific purposes might be useful.
