Background: Rosacea is a chronic inflammatory skin disorder characterized by erythema, papules, ocular symptoms, and heightened sensitivity. Patients with neurogenic symptoms such as burning or stinging remain particularly difficult to manage. Current guidelines often underrepresent energy-based devices (EBDs), pigmentary sequelae, psychosocial burden, and ocular comorbidities. Objective: To examine Korean dermatologists’ expert perspectives on rosacea management, focusing on skin sensitivity, neurogenic symptoms, pigmentary changes, psychosocial impact, ocular involvement, and EBD use. Methods: A web-based, 29-item survey was administered to 25 board-certified Korean dermatologists (May–June 2025). Quantitative and qualitative responses were analyzed. Results: Erythematotelangiectatic and papulopustular phenotypes with sensitivity skin predominated. EBDs (pulsed dye laser, intense pulsed light) were frequently used but limited by cost and sensitivity issues. Neurogenic symptoms were recognized but rarely treated with neuromodulators. Post-inflammatory hyperpigmentation was infrequent, yet monitoring was inconsistent.Psychosocial and ocular aspects were acknowledged but seldomly systematically addressed.Respondents expressed interest in emerging adjunctive treatments such as cold plasma, skin boosters, and holistic care approaches. Conclusion Korean dermatologists adopt individualized strategies for rosacea, yet practice gaps remain regarding neurogenic symptoms, pigmentary complications, and psychosocial and ocular comorbidities. Findings support the need for updated multidisciplinary, phenotype-driven guidelines aligned with real-world practice.

Background: Atopic dermatitis (AD) is a common skin disease with a wide range of symptoms. Due to the rapidly changing treatment landscape, regular updates to clinical guidelines are needed. Objective: This study aimed to update the guidelines for the treatment of AD to reflect recent therapeutic advances and evidence-based recommendations. Methods: The Patient characteristics, type of Intervention, Control, and Outcome framework was used to determine 48 questions related to AD management. Evidence was graded, recommendations were determined, and, after 2 voting rounds among the Korean Atopic Dermatitis Association (KADA) council members, consensus was achieved. Results: This guideline provides treatment guidance on advanced systemic treatment modalities for AD. In particular, the guideline offers up-to-date treatment recommendations for biologics and Janus-kinase inhibitors used in the treatment of patients with moderate to severe AD.It also provides guidance on other therapies for AD, along with tailored recommendations for children, adolescents, the elderly, and pregnant or breastfeeding women. Conclusion KADA’s updated AD treatment guidelines incorporate the latest evidence and expert opinion to provide a comprehensive approach to AD treatment. The guidelines will help clinicians optimize patient-specific therapies.

Evidence was graded, recommendations were determined, and, after 2 voting rounds among the Korean Atopic Dermatitis Association (KADA) council members, consensus was achieved. Results: The guidelines provide detailed recommendations on foundational therapies, including the use of moisturizers, cleansing and bathing practices, allergen avoidance, and patient education. Guidance on topical therapies, such as topical corticosteroids and calcineurin inhibitors, is also provided to help manage inflammation and maintain skin barrier function in patients with AD. Additionally, recommendations on conventional systemic therapies, including corticosteroids, cyclosporine, and methotrexate, are provided for managing moderate to severe AD. Conclusion KADA’s updated AD guidelines offer clinicians evidence-based strategies focused on basic therapies, topical therapies, and conventional systemic therapies, equipping them to enhance quality of care and improve patient outcomes in AD management.

Background: Mammalian orthoreovirus type 3 (MRV3), which is responsible for gastroenteritis in many mammalian species including pigs, has been isolated from piglets with severe diarrhea. However, the use of pig-derived cells as an infection model for swineMRV3 has rarely been studied. Objectives: This study aims to establish porcine intestinal organoids (PIOs) and examine their susceptibility as an in vitro model for intestinal MRV3 infection. Methods: PIOs were isolated and established from the jejunum of a miniature pig.Established PIOs were characterized using polymerase chain reaction (PCR) and immunofluorescence assays (IFAs) to confirm the expression of small intestine-specific genes and proteins, such as Lgr5, LYZI, Mucin-2, ChgA, and Villin. The monolayered PIOs and threedimensional (3D) PIOs, obtained through their distribution to expose the apical surface, were infected with MRV3 for 2 h, washed with Dulbecco’s phosphate-buffered saline, and observed. Viral infection was confirmed using PCR and IFA. We performed quantitative realtime reverse transcription-PCR to assess changes in viral copy numbers and gene expressions linked to intestinal epithelial genes and antiviral activity. Results: The established PIOs have molecular characteristics of intestinal organoids. Infected PIOs showed delayed proliferation with disruption of structures. In addition, infection with MRV3 altered the gene expression linked to intestinal epithelial cells and antiviral activity, and these effects were observed in both 2D and 3D models. Furthermore, viral copy numbers in the supernatant of both models increased in a time-dependent manner. Conclusions We suggest that PIOs can be an in vitro model to study the infection mechanism of MRV3 in detail, facilitating pharmaceutical development.

Background: This study was conducted to examine the effect of adverse childhood experiences on depressive symptoms in university students and to verify whether positive psychological resources act as a protective factor for depression. Methods: Data from 1,317 young adults aged 18-29 years who took part in the university-based cross-sectional survey were analyzed. All participants completed self-report questionnaires that included demographic variables, the Adverse Childhood Experience (ACE) Scale, the Patient Health Questionnaire-9, and the Positive Resources Test. Results: The incidence of depression was 33.3% and was higher in women than in men. Based on the 10 ACE categories, 32.7% of the students reported one or more adverse childhood experiences, and 14.4% reported two or more forms of adverse childhood experiences. Students with depressive symptoms were likely to report more traumatic experiences in childhood and fewer positive psychological resources than those without depressive symptoms. Hierarchical regression analysis indicated that positive psychological resources moderated the relationship between adverse childhood experiences and depression. Conclusion Based on these results, professionals should consider identifying adverse childhood experiences early and provide active mental health service support, including positive psychological and social resources for individuals who have adverse experiences during childhood.

Meckel diverticulum is a common congenital malformation of the gastrointestinal tract and can cause complications such as ulceration, hemorrhage, intussusception, and perforation. This report describes a very rare complication of an enterovesical fistula associated with chronic Meckel diverticulum. A 51-year-old male presented with over 10 years of persistent pyuria. Tests were performed to rule out malignancy, including serum prostate-specific antigen level, urine cytology, bacterial culture, cystoscopy, and bladder computed tomography. An enterovesical fistula was identified, and laparoscopic exploration was performed. The findings suggested enterovesical fistula formation caused by chronic inflammation at the tip of a Meckel diverticulum. Segmental resection of the small bowel including the diverticulum and primary repair of the urinary bladder along with partial cystectomy were performed. The postoperative clinical course was uneventful. An enterovesical fistula is a very rare complication resulting from chronic inflammation of a Meckel diverticulum.

Objectives: Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study investigated the impact of maternal ACEs on PTSD in the offspring. Methods: A total of 156 mothers with children aged 13–18 years completed the Diagnostic Interview Schedule for Children (DISC) Predictive Scales to determine the presence of psychiatric disorders in their offspring. The subjects completed the ACE questionnaire and the Early Trauma Inventory Self-Report-Short Form. Multivariable logistic regression was used to analyze the relationship between maternal ACEs and PTSD in the offspring. Results: Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). Conclusion Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.

BACKGROUND: Social anxiety and suicide are serious common problems in college students. However, there are few studies on the relationship between social anxiety symptoms and suicidal risk. Therefore, we evaluated the associationbetween social anxiety symptoms and suicidal risk in college students.METHODS: A total of 579 college students were recruited for a college-based cross-sectional survey in the Jeju area. The participants completed a questionnaire gathering sociodemographic information; they also completed the Korean Social Avoidance and Distress Scale (SADS) to assess social anxiety symptoms and the Center for Epidemiologic Studies Depression Scale (CES-D) to assess depressive symptoms. To obtain information regarding suicidal risk, we administered the Korean version of the Suicide module of the Mini International Neuropsychiatric Interview (M.I.N.I.).RESULTS: The prevalence of higher levels of social anxiety symptoms among college students was 28.0% (n=162). A higher level of social anxiety symptoms resulted in a 2.10-times higher suicidal risk after adjusting for depression in college students (95% confidence interval, 1.05-4.23; p=0.037).CONCLUSION: Based on the results of this study, social anxiety symptoms should be managed and controlled to prevent suicidality in Korean college students.
