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 and Objectives: This study aimed to analyze postoperative performance and mapping characteristics of cochlear implants (CIs) by comparing patients with autism spectrum disorder (ASD) to those without ASD, and to suggest CI mapping solutions in patients with ASD.Subjects and Method This retrospective study enrolled 10 children with ASD and hearing disabilities, who received simultaneous bilateral CI (ASD group), and 20 children with bilateral hearing disabilities, who received simultaneous bilateral CI at the same age (control group). CI performance was analyzed using speech perception tests (categorical auditory performance score and monosyllable, bisyllable, and Ling’s 6 tests) and a sound field test. The mapping characteristics focused on variables related to stimulus intensity and fine-tuning. Results: The performance of the ASD group was significantly poorer than that of the control group in all speech perception and sound field tests. At the comfortable (C) and threshold (T) levels, the ASD group scored significantly lower than the control group. The dynamic range of ASD group was significantly narrower than the control group. The ASD group had significantly lower pulse width, sensitivity, and volume than control group. Conclusion CI mapping in the ASD group showed practical limitations. To avoid overstimulation in patients with ASD, the dynamic range should be set narrow, or the C/T level should be set lower than normal. Key control factors, such as pulse width, sensitivity, and volume, should be set lower than the control group. Although lower performance from CI is generally expected in the ASD group, CI mapping in the ASD group requires a long-term approach with dedicated efforts and patience.

Gastric cancer is one of the most common cancers in both Korea and worldwide. Since 2004, the Korean Practice Guidelines for Gastric Cancer have been regularly updated, with the 4th edition published in 2022. The 4th edition was the result of a collaborative work by an interdisciplinary team, including experts in gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology, and guideline development methodology. The current guideline is the 5th version, an updated version of the 4th edition. In this guideline, 6 key questions (KQs) were updated or proposed after a collaborative review by the working group, and 7 statements were developed, or revised, or discussed based on a systematic review using the MEDLINE, Embase, Cochrane Library, and KoreaMed database. Over the past 2 years, there have been significant changes in systemic treatment, leading to major updates and revisions focused on this area.Additionally, minor modifications have been made in other sections, incorporating recent research findings. The level of evidence and grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation system. Key factors for recommendation included the level of evidence, benefit, harm, and clinical applicability. The working group reviewed and discussed the recommendations to reach a consensus. The structure of this guideline remains similar to the 2022 version.Earlier sections cover general considerations, such as screening, diagnosis, and staging of endoscopy, pathology, radiology, and nuclear medicine. In the latter sections, statements are provided for each KQ based on clinical evidence, with flowcharts supporting these statements through meta-analysis and references. This multidisciplinary, evidence-based gastric cancer guideline aims to support clinicians in providing optimal care for gastric cancer patients.

Background: The ongoing medical crisis in Korea has severely impacted the operational environment of intensive care units (ICU), posing significant challenges to quality care for critically ill patients. This study aimed to evaluate the effects of the ongoing crisis on ICUs. Methods: A survey was conducted in July 2024 among intensivists in charge of ICUs at institutions accredited by the Korean Society of Critical Care Medicine for critical care. The survey compared data from January 2024 (pre-crisis) and June 2024 (post-crisis) on the number ICU beds, staffing composition, work hours, and the number and roles of nurse practitioners. Results: Among the total of 71 participating ICUs, 22 experienced a reduction in the number of operational beds, with a median decrease of six beds per unit, totaling 127 beds across these ICUs. The numbers of residents and interns decreased from an average of 2.3 to 0.1 per ICU, and the average weekly working hours of intensivists increased from 62.3 to 78.8 hours. Nurse practitioners helped fill staffing gaps, with their numbers rising from 150 to 242 across ICUs, and their scope of practice expanded accordingly. Conclusions The medical crisis has led to major changes in the critical care system, including staffing shortages, increased workloads, and an expanded role for nurse practitioners. This is a critical moment to foster interest and engage in active discussions aimed at creating a sustainable and resilient ICU system.
