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 To identify the prevalence and risk factors associated with diaper dermatitis in Thai children aged 1–24 months. Methods This was a cross-sectional study of 1153 participants using structural questionnaires, which was conducted at Khon Kaen University Faculty of Medicine Pediatric department in Thailand. Univariate and multivariate logistic regression analyses were used to test the association between diaper dermatitis and its possible risk factors. Results The prevalence of diaper dermatitis among the study population was 36.1%, a rate which significantly decreased with age. The highest prevalence was found in subjects who were one to six months old. Risk factors that had a statistically significant association with diaper dermatitis in both univariate and multivariate analysis were i) diaper changing fewer than three times/night, ii) previous episodes of diaper rash, iii) using cloth diapers, and iv) topical application of baby talcum powder to the diaper area. Conclusions Frequent diaper changings during the daytime do not compensate for fewer changings during the night. Moreover, the use of baby talcum powder on the diaper area significantly increased the risk of diaper dermatitis among the study population. These findings should be applied in future preventive strategies for diaper dermatitis in this age group.

Objectives Dermatological disorders are common in general pediatric practice. This study aimed to examine common skin problems and the manner in which they tend to be misdiagnosed. Methods A cross-sectional study was conducted from January 2015 to December 2016 using medical record data from the Pediatric Dermatological Outpatient Unit at Khon Kaen University, Faculty of Medicine. Results A total of 1551 visits by 769 patients were documented during the study period. A total of 114 presenting diseases were recorded. The most common skin disease in the study population was dermatitis (unspecified) (88/769, 11.4%), followed by atopic dermatitis (76/769, 9.8%) and infantile hemangioma (72/769, 9.3%). There was a total of 55 (48.2%) misdiagnosed diseases. Some unique cutaneous diseases were undiagnosed because of their rarity. However, the percentages of common cutaneous diseases, such as tinea capitis and molluscum contagiosum, which had been misdiagnosed, were also high (62.50% [95% confidence interval = 24.49–91.48] and 71.43% [95% confidence interval = 29.04–96.33], respectively). Conclusion A large percentage of misdiagnoses of common cutaneous diseases may be due to general pediatricians being undereducated in the field of dermatology. Accurate recognition and appropriate management of these conditions should be emphasized for educating general pediatricians in the future.
