Purpose: The study aimed to explore the prevalence and possible risk factors to prevent the face mask related adverse skin reactions during the ongoing COVID-19 after a recommendation of face mask wearing for public use in Thailand. Results: The prevalence of face mask related adverse skin reactions was 454 cases (54.5%), of which acne was the most frequent (399; 39.9%), followed by rashes on the face (154; 18.4%), and itch symptoms (130; 15.6%). Wearing a surgical mask showed a higher risk of adverse skin reaction compared to a cloth mask, OR (95% CI) = 1.54 (1.16-2.06). A duration of face mask wearing of more than 4 hours/day and the reuse of face masks increased the risk of adverse skin reactions compared to changing the mask every day, adjusted OR(95% CI) = 1.96 (1.29-2.98), and 1.5 (1.11-2.02). Conclusion: Suggestions were made for wearing a cloth mask in non-health care workers (HCW) to decrease the risk of face mask related adverse skin reactions. This suggestion could potentially help in decreasing the demand of surgical masks which should be reserved for the HCW population during the ongoing COVID-19 pandemic.

Purpose: This study aimed to explore the prevalence of and possible risk factors for hand eczema with respect to the dissemination of information about new hand hygiene habits to protect against ongoing COVID-19 cross-transmission. The authors conducted a survey among health care workers (HCWs) and non-HCW populations in Khon Kaen, Thailand. Results: A total of 805 participants participated. The prevalence of hand eczema in the study population was 20.87%. There were several risk factors, including working as a HCW, having a history of previous hand eczema, having underlying atopic dermatitis, wearing gloves in everyday life, and washing hands frequently (more than 10 times/day). Hand hygiene with alcohol-based products was shown to be a risk factor for hand eczema, (OR (95% CI) 1.86 (1.03-3.35), P = .04). Conclusion: In terms of hand eczema prevention, we suggest that the use of alcohol-based products should be discontinued if other handwashing methods are available. The following factors increase the risk of hand eczema: being a HCW, having previous hand eczema, and having underlying atopic dermatitis. Proper strategies in terms of hand eczema prevention should be addressed, especially in this group, since we need to continue performing hand hygiene during the ongoing COVID-19 pandemic.

Background Enhancing the skin barrier in high‐risk neonates by daily use of emollients during infancy might prevent atopic dermatitis (AD); however, there have been no studies on this topic in a country with a tropical climate. Climate may affect the results of the use of emollients in neonates for AD prevention and possible adverse cutaneous eruptions. Objectives To test the hypothesis that emollients used during infancy can prevent AD in high‐risk neonates in a country with a tropical climate and to evaluate other possible adverse cutaneous eruptions in this population. Methods This was a randomized controlled study in a tertiary care hospital with a 6 months' duration. Eligible neonates were randomly assigned to receive either emollient and skincare advice (emollient group) or skincare advice only (control group). The intervention was started within 3 weeks of birth. Results The emollient group showed a significant reduction in the cumulative incidence of AD at 6 months (relative risk, 0.39; 95% CI 0.24–0.64; P < 0.001). The emollient group started to develop AD later and had a lower severity of AD than the control group (P < 0.001). Compared to moderate adherence, low adherence to emollient application was associated with a lower number of patients with AD (P = 0.008). Potentially emollient‐related cutaneous eruptions, such as miliaria, and suspected cutaneous infections, such as impetigo, were more frequent in the emollient group. Exposure to passive smoking showed a significant difference in the development of AD compared to non‐smoking exposure, both during pregnancy and after the child's birth (P < 0.001). Conclusions This study suggests that, in a tropical climate, emollient applied to the skin of at‐risk neonates on an ‘as needed’ basis (depending on environmental factors, level of skin dryness), rather than on a ‘daily basis', can provide a substantial benefit for AD prevention.
