Background: Daily usage of facial masks during coronavirus disease 2019 pandemic influenced on facial dermatoses. Objective: This study investigated the impact of mask-wearing habits on facial dermatoses. Methods: A nationwide, observational, questionnaire-based survey was conducted from July through August 2021, involving 20 hospitals in Korea. Results: Among 1,958 facial dermatoses, 75.9% of patients experienced aggravation or development of new-onset facial dermatoses after wearing masks. In aggravated or newly developed acne patients (543 out of 743), associated factors were healthcare provider, female gender, and a long duration of mask-wearing. Irritating symptoms, xerosis, and hyperpigmentation were more frequently observed in this group. Aggravated or newly developed rosacea patients (515 out of 660) were likely to be female, young, and have a long duration of mask-wearing per day. Seborrheic dermatitis patients who experienced aggravation or de novo development (132 out of 184) were younger, and they more frequently involved the chin and jaw in addition to the nasolabial folds and both cheeks. Contact dermatitis patients (132 out of 147) with aggravation or de novo development tended to be female, involve both cheeks, and complain of pruritus. Aggravated or newly developed atopic dermatitis patients (165 out of 224) were more likely to be female, and had a higher baseline investigator global assessment score before mask-wearing. Conclusion Clinical features and factors related to aggravation were different according to the types of facial dermatoses.

Background: More than half of acne patients have truncal acne on their chest, back, and shoulders. However, since most studies on acne have focused on the face, data on clinical characteristics and proper management for truncal acne are insufficient. Objective: To establish a Korean Acne Rosacea Society (KARS) consensus for experts’ perception and treatment patterns of truncal acne. Methods: We conducted two rounds of the Dephi technique to gather expert opinion and reach a consensus on truncal acne. The first round comprised 48 questionnaires focusing on various aspects such as epidemiology, clinical features, diagnosis, treatment, prognosis and more, while second rounds consisted of 26 questionnaires. Results: A total of 36 dermatologists (36/38 KARS members, 94.7%) completed this survey. In the first-round survey, consensus was reached on 20 out of the 48 questions (41.7%). In the secondround questionnaire, consensus was achieved on 9 of the 26 questions (34.6%). The most unresponsive lesion to truncal acne treatment was scars (atrophic/hypertrophic). The most commonly used treatments for each non-inflammatory and inflammatory truncal acne lesions were selected to use topical retinoids (78.1% of the responders) and oral antibiotics (93.8% of the responders). Conclusion Our study has yielded valuable insights into the epidemiology, clinical manifestations, diagnosis, treatment, and quality of life of patients with truncal acne. We anticipate that this study will inspire further comprehensive research for individuals with truncal acne.

OBJECTIVE: To analyze the available data on the anti-anger effects of herbal medicines (HMs) as well as their underlying mechanisms in rat models. METHODS: From 6 electronic databases [PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, Oriental Medicine Advanced Searching Integrated System (OASIS), and Research Information Sharing Service (RISS)], relevant animal experiments were searched by using "anger," "rats," and "animal" as search keywords. The last search was conducted on November 22, 2019, and all experiments involving rat models of anger and treatment using HMs published until the date of the search were considered. RESULTS: A total of 24 studies with 16 kinds of HMs were included. Most studies have used the "tail irritating method" and "social isolation and resident intruder" method to establish anger models. According to the included studies, the therapeutic mechanisms of HMs for anger regulation and important herbs by their frequency and/or preclinical evidence mainly incladed regulation of hemorheology (Bupleuri Radix, Paeoniae Radix Alba, and Glycyrrhizae Radix), regulation of sex hormones (Bupleuri Radix, Cyperi Rhizoma, and Paeoniae Radix Alba), regulation of neurotransmitters (Cyperi Rhizoma), regulation of anger-related genes (Bupleuri Radix, Glycyrrhizae Radix, and Paeoniae Radix Alba), and other effects. Overall, Liver (Gan) qi-smoothing herbs including Bupleuri Radix and Cyperi Rhizoma were the most frequently used. CONCLUSIONS This review found the frequent methods to establish an anger model, and major mechanisms of anti-anger effects of HMs. Interestingly, some Liver qi-smoothing herbs have been frequently used to investigate the anti-anger effects of HM. These findings provide insight into the role and relevance of HMs in the field of anger management.

BACKGROUND: Tinea barbae(TB) is a rare dermatophytosis localized on the bearded areas of the face and neck. OBJECTIVE: The purpose of this study was to elucidate the epidemiological, clinical and mycological characteristics of TB. METHODS: During the 24-year-period from 1983 to 2004, 74 patients with TB were evaluated in regard to annual incidence, the distribution of the subjects according to age, season, involved site, occupation, a place of residence and concurrent fungal infection. Patients with TB were further assessed concerning causative agents by fungal culture and their association with clinical type and a place of residence. RESULTS: In epidemiologic aspect, annual incidence was increased until 1989, thereafter gradually decreased. TB showed peak incidence in April in monthly distribution. TB occurred predominantly in middle-aged adults, especially in fifties in age distribution and countryfolk in residential distribution. In clinical aspect, superficial type was the most common in clinical types, followed by follicular and kerion type. Upper lip was affected mostly. In mycologic aspect, fungal culture showed positive results in 57 patients. Trichophyton(T.) rubrum was the most common causative agents followed by T. mentagrophytes and T. verrucosum. Thirty six patients had concurrent fungal infection and tinea pedis was the most common. CONCLUSION: The result suggests that although the incidence of TB is decreasing, it is important not only to isolate cattle with dermatophytoses from people but also to treat concurrent dermatophytoses in order to decrease the incidence

OBJECTIVE: To investigate the fertility outcomes after abdominal or laparoscopic myomectomy in infertile patients with no other infertility factors except uterine myoma. METHODS: From January, 1992 to December, 1998, abdominal or laparoscopic myomectomy was performed in 76 patients with desire for children and no other recognizable infertility factors. The medical records were reviewed retrospectively. The mean duration of postoperative follow-up was 23.4+/-21.2 months(1~82 months). RESULTS: After myomectomy, 35 patients(46.1%) became pregnant during the follow-up period, especially with 24(68.6%) within 12 months. Excluding 7 cases of spontaneous abortion and 2 cases of intrauterine fetal death, 26 patients(74.3%) had a viable birth. Parity, duration of infertility, number, type and location of myoma, and the proportion of opening the intrauterine cavity during operation were not significantly different between the pregnant and nonpregnant groups. However, the size of uterine myoma was significantly larger in the pregnant group(p<0.05). CONCLUSION: We obtained a reasonable pregnancy rate in infertile patients with uterine myoma as a sole infertility factor. The size of myoma may influence the postmyomectomy pregnancy rate, and this may indicate a more beneficial effect of myomectomy in infertile patients with a relatively larger myoma.
