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.

Purpose: Robotic single-site plus one-port myomectomy (RSOM) was designed to reduce the number of incision sites for greater cosmetic satisfaction of patients while retaining the benefits of conventional robotic multi-site myomectomy (CRM). Robotic single-site plus two-port myomectomy (RSTM) eliminated one port relative to conventional CRM, and RSOM achieved the same advantage with respect to RSTM. This study aimed to compare RSOM with RSTM in terms of their respective methodologies and surgical outcomes. Materials and Methods: The medical records of 230 patients who had undergone RSOM and 146 patients who had undergone RSTM were reviewed. The groups’ surgical outcomes were compared using propensity score matching (PSM) analysis. Results: In the total data, RSOM had a shorter operative time (135.1±57.4 min vs. 149.9±46.2 min, p=0.009) and a shorter hospital stay (5.2±0.5 days vs. 5.4±0.7 days, p=0.033) relative to RSTM. The PSM analysis showed that there were no statistically significant intergroup differences in the patients’ baseline characteristics. Regarding the surgical outcomes, the RSOM group showed shorter operative time (129.2±49.3 min vs. 148.7±46.3 min, p=0.001) compared to the RSTM group. Conclusion Compared with RSTM, RSOM was associated with shorter operative time. Additionally, more detailed comparative and prospective studies are needed to evaluate RSOM relative to RSTM.

Background: The Korean government is implementing policy to reduce medical costs and improve treatment related for human immunodeficiency virus (HIV) patients. The level of cost reduction and the benefits provided vary depending on how individuals with HIV utilize the system. This study aims to determine exact HIV prevalence by analyzing healthcare utilization patterns and examining differences in healthcare usage based on how individuals pay for their medical expenses. Materials and Methods: We analyzed National Health Insurance Service (NHIS) claims data from 2002 to 2021. From a total of 106,675 individuals with at least one HIV-related claim, 22,779 participants were selected for this study. Results: Data from Korea Disease Control and Prevention Agency annual reports indicated that 93% of HIV patients were male, while NHIS data showed 84%. In the analysis of those exempted from registration, it was found that the registration rate for female patients is notably low, with adults between the ages of 20 and 40 making up 80% of the total. The registration rate in Gangwon State was lower than Seoul. The treatment experience rate was much higher in the registered group (93.0%) than the unregistered group (4.9%). Also, there was a big difference in treatment continuity rates: 76.2% for registered individuals and 2.8% for non-registered individuals. Conclusion The exempt calculation system for health insurance improves HIV care. However, those diagnosed anonymously or with reduced medical costs may be less likely to continue HIV treatment, so a new policy is needed to ensure anonymity and treatment continuity.

Adult-onset Still’s disease (AOSD) is a rare systemic inflammatory disease characterized by spiking fever, arthralgia, skin rashes, and hyperferritinemia. The rash is usually salmon-colored, non-itchy, accompanied by fever, and disappears with an improvement of fever. However, in some cases, the rash persisted regardless of fever. Here, we present a case of AOSD with an atypical persistent rash that showed histological findings resembling those of neutrophilic urticarial dermatosis. The patient was a 60-year-old woman with high fever, arthralgia, and a persistent flagellated skin rash. Despite systemic steroid treatment, the patient developed a serious complication: macrophage activation syndrome. Since this case presented with an atypical persistent rash with histological resemblance to neutrophilic urticarial dermatosis, we report its contribution to the further study of AOSD.

Background: Various treatment modalities are used to treat keloids. However, a comprehensive assessment comparing the effectiveness of these modalities in terms of patient-reported outcomes is warranted. Objective: To assess and compare the effectiveness of various treatment modalities for keloids. Methods: We assessed treatment outcomes in a cohort of 250 patients diagnosed with keloids.The patients were categorized into four treatment groups: triamcinolone acetonide (TA), TA + cryotherapy, TA + pulsed dye laser (PDL), and TA + cryotherapy + PDL. The Vancouver Scar Scale was used to evaluate the keloid severity before and after treatment. Results: Significant differences were noted in the Vancouver Scale scores among the treatment groups (p=0.023). Notably, the TA + cryotherapy + PDL group exhibited the most substantial improvement in the Vancouver Scale scores, whereas the TA + PDL group showed the least difference. Pliability was the most significantly improved in the TA + cryotherapy + PDL group (p=0.039). Male patients experienced a greater reduction in pigmentation scores than female patients (p=0.037). Conclusion Our findings highlight the effectiveness of combined therapies, particularly TA + cryotherapy + PDL, in improving keloid-related parameters. These results offer valuable insights for clinicians in tailoring keloid treatment strategies and support the implementation of combination therapies for enhanced outcomes. This study underscores the importance of comprehensively assessing treatment modalities for keloid management. Combination therapies such as TA + cryotherapy + PDL irradiation have demonstrated significant promise in improving keloid characteristics.

Background/Aims: We aimed to compare the effectiveness and safety of Janus kinase inhibitors (JAKi) vs. biologic disease- modifying antirheumatic drugs (bDMARD) in Korean patients with rheumatoid arthritis (RA) who had an inadequate response to conventional synthetic DMARDs. Methods: A quasi-experimental, multi-center, prospective, non-randomized study was conducted to compare response rates between JAKi and bDMARDs in patients with RA naïve to targeted therapy. An interim analysis was performed to estimate the proportion of patients achieving low disease activity (LDA) based on disease activity score (DAS)–28– erythroid sedimentation rate (ESR) (DAS28-ESR) at 24 weeks after treatment initiation and to evaluate the development of adverse events (AEs). Results: Among 506 patients enrolled from 17 institutions between April 2020 and August 2022, 346 (196 JAKi group and 150 bDMARD group) were included in the analysis. After 24 weeks of treatment, 49.0% of JAKi users and 48.7% of bDMARD users achieved LDA (p = 0.954). DAS28-ESR remission rates were also comparable between JAKi and bDMARD users (30.1% and 31.3%, respectively; p = 0.806). The frequency of AEs reported in the JAKi group was numerically higher than that in the bDMARDs group, but the frequencies of serious and severe AEs were comparable between the groups. Conclusions Our interim findings reveal JAKi have comparable effectiveness and safety to bDMARDs at 24 weeks after treatment initiation.

The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.
