ABSTRACT
Background@#Dermatophyte infection is one of the most common skin diseases affecting the skin, hair, and nails. Despite widespread recognition of the disease, missing details and misperceptions are commonplace in the general population. @*Objective@#This study aimed to investigate the public perception and behavior regarding dermatophytosis of the hands and feet. @*Methods@#This results from an online survey conducted between July 2022 and August 2022. The survey included 1,000 Korean participants aged 20 to 69 years, of whom 60% experienced symptoms of tinea pedis or onychomycosis. The questionnaire focused on the awareness and personal experience of tinea pedis and perception of the treatment of dermatophytosis. @*Results@#Of the 1,000 participants, nearly 80% regarded tinea pedis as a common skin condition by which anyone can be affected. Furthermore, 88.4% had heard that the treatment of tinea pedis could be harmful, causing skin rash (60.4%) and worsening liver function (48.5%). Among 896 participants who noticed suspicious symptoms, 81.2% did not visit the clinic because it was not severe (50.1%) and seemed easily manageable (25.7%). Of the respondents, 84.4% preferred to meet dermatologists rather than non-dermatologist doctors regarding skin diseases, mainly because of trust in experts and belief in a faster cure. @*Conclusion@#Providing accurate and detailed information via online media, educational campaigns, and medical papers can rectify misconceptions and improve patient appliance, contributing to public skin health.
ABSTRACT
Background@#Avoiding causative allergens is important for controlling the clinical course of atopic dermatitis (AD). Allergen sensitization is influenced by many factors, such as the environmental factors. Although socioeconomic development, climate, and lifestyle have changed and the prevalence of allergic diseases has increased in Korea over the past few decades, there is little information about changes in common allergens over time. @*Objective@#This study aimed to identify the trends of common allergens in patients with AD over a 10-year period based on the results of the multiple allergen simultaneous test (MAST). @*Methods@#We retrospectively reviewed the medical records of 1,414 patients with AD (603 adults and 811 children) over a period of 10 years. The serum total immunoglobulin E (IgE) and specific IgE levels of 41 allergens were determined using the MAST. @*Results@#House dust and house dust mites were the most prevalent allergens in both adult and pediatric patients during the 10-year period; however, the percentage of higher-class responses has decreased in recent years. The number of patients sensitized to house dust, cats, and egg whites increased, whereas that of patients sensitized to cockroaches, storage mites, beef, and rice decreased for both adults and children. No significant changes were observed in the total number of sensitizing allergens over time. @*Conclusion@#Common allergens in patients with AD have change over time. Based on the findings of this study, physicians and patients should consider changing their disease prevention and management strategies.
ABSTRACT
A 47-year-old man with a 25-year history of Crohn’s disease, presenting asymptomatic erythematous scaly patches (size, 1∼3 cm in diameter) on his back, left hand, right wrist, left ankle, and left sole, visited our clinic. Histopathological examination of the lesions revealed Bowen’s disease. Herein, we report a rare case of multiple Bowen’s disease in the skin, away from the anogenital region, in a patient with Crohn’s disease.
ABSTRACT
Background@#The use of makeup is popular among Korean adolescents. With the increased use of color cosmetics, there are concerns that heavy application may cause skin problems or aggravate acne, a condition highly prevalent in this age group. Other than makeup, cosmetic products targeting acne are also easily accessible and often used. Currently, little is known about the use of these products in Korean middle school students and their understanding of its effect on the skin. @*Objective@#This study investigated the prevalence of “color cosmetics” and cosmetics targeting acne” among Korean students and their awareness of the effects of these products on their skin.Method: A questionnaire survey was conducted of 192 students from Dawon Middle School in Hwasung. The questionnaire consisted of detailed inquiries regarding the use of color cosmetics and cosmetics targeting acne and their effect on the skin. @*Results@#A total of 192 responses were analyzed. Sixty-three (32.8%) students reported experience with putting on makeup. Among these 63 students, 35 (55.5%) responded that their skin condition had worsened after applying makeup, which was associated with the frequency and extent of color cosmetic use (p＜0.05). Among the 106 (52.2%) students with acne, 63% reported having tried acne-targeting cosmetics. Approximately 14.3% of this population reported feeling very satisfied with the effect of these cosmetics on acne. @*Conclusion@#The results of our study indicated that a significant percentage of middle school adolescents are using makeup. As skin troubles may arise with the use of color cosmetics, an educational guide on minimizing application and properly removing the products should be provided to this population. Acne is highly prevalent in adolescents and cosmetics targeting acne are easily accessible. The belief that acne-targeting cosmetics can replace hospital treatment can be risky and should be thoroughly explained by dermatologists.
ABSTRACT
Cosmetic facial tattoo as semi-permanent make-up for the eyebrows is gaining popularity in Korea. Consequently, the incidence of tattoo-related complications, including local skin infections, allergic reactions, and non-allergic granulomatous reactions, is also increasing. Herein, we report two cases of granulomatous reactions to semi-permanent eyebrow tattoos. Clinicians should always keep in mind that both systemic sarcoidosis and delayed complications associated with tattooing can manifest as granulomatous reactions. Therefore, every granulomatous reaction at the tattoo site should be evaluated to differentiate sarcoidosis from foreign body granuloma.
ABSTRACT
Background@#Psoriasis is a chronic condition that negatively influences a patient’s daily life. However, there is limited evidence on the changes in quality of life (QOL) of Korean psoriasis patients treated with ustekinumab measured using both dermatologic- and psoriasis-specific responder-based questionnaires. @*Objective@#To evaluate the effect of ustekinumab on the QOL of psoriasis patients. @*Methods@#Seventy psoriasis patients treated with ustekinumab were asked to retrospectively complete questionnaires about the effect of ustekinumab on their QOL before and after treatment. Psoriasis area and severity index (PASI) were assessed on the basis of clinical pictures taken at baseline and subsequent visits. The QOL of each patient was assessed on the basis of the dermatology-specific Dermatology Life Quality Index (DLQI) and psoriasis-specific Psoriasis Disability Index (PDI). @*Results@#The total and all-domain scores in the DLQI and PDI decreased after at least four administrations of ustekinumab (p＜0.05). Moreover, disease severity was significantly related to poor QOL. Of note, employment status was specifically associated with DLQI scores while age was associated with disease-specific QOL. @*Conclusion@#The QOL significantly improved in Korean psoriasis patients treated with ustekinumab, suggesting a positive influence of the treatment on the patients’ subjective perceptions. Severe clinical features, unemployment status, and older age may lead to lower QOL.

ABSTRACT
BACKGROUND: Chronic urticaria is defined as repeated episodes of wheals lasting for 6 weeks or longer. Nowadays, the role of vitamin D in various chronic diseases is a matter of great interest, but limited data is available on the vitamin D status in patients with chronic urticaria. OBJECTIVE: The goal of this study was to investigate the relationship between vitamin D status and clinical characteristics of chronic urticaria. METHODS: The clinical records of 72 patients with chronic urticaria, 26 with acute urticaria and 26 with atopic dermatitis, along with 72 healthy controls, were retrospectively reviewed. RESULTS: The serum 25-(OH)D3 level was found to be significantly reduced in patients with chronic urticaria compared to those in the other groups. In particular, the proportion of patients with critically low vitamin D levels (<10 ng/ml) was significantly higher in the chronic urticaria group than in the other groups. The serum vitamin D levels showed significant negative associations with urticaria activity score and disease duration. In addition, serum vitamin D levels were significantly lower in subjects with a positive autologous serum skin test than in subjects with a negative result. CONCLUSION: In conclusion, the serum vitamin D level was more likely to be critically low in patients with chronic urticaria, and an inverse relationship with disease severity and disease duration was observed. These findings may open up the possibility of the clinical use of vitamin D as a contributing factor in the pathogenesis of chronic urticaria and a predictive marker for disease activity in chronic urticaria.

Morphea, localized scleroderma, is a connective tissue disease characterized by localized, circumscribed sclerotic patches, or plaques of the skin. The pathogenesis of morphea is still unclear. Central diabetes insipidus is a disease characterized by excessive thirst and urination. In more than half of the cases of central diabetes insipidus, the etiology is still unknown. We experienced the case of morphea and verruca plana in a 32-year old female with a history of central diabetes insipidus. Central diabetes insipidus might have influenced disrupting the homeostasis of the endocrine or immune environment. In the state of disrupted homeostasis, there might be an increased chance for morphea and disseminated verruca plana to develop easily. Based on this, we suppose the possible mechanism about the morphea and disseminated verruca plana developed in central diabetes insipidus.
