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.

Meningioma arises from arachnoid cap cells and is a common intracranial neoplasm; however, primary extracranial meningioma is rare, accounting for only 1%–2% of cases and is therefore frequently misdiagnosed. We report a case of primary extracranial meningioma arising in the temporal region without intracranial or dural involvement. A 66-year-old woman presented with a slowly enlarging mass in the left temporal region for approximately 10 years, without pain or limitation of mouth opening. Computed tomography revealed a 2.1× 2.7× 4.6 cm mass between the temporalis muscle and the skull, with no intracranial extension. Fine-needle aspiration suggested a spindle-cell neoplasm, and complete excision was performed via a coronal scalp incision for diagnosis and treatment. Histopathologic and immunohistochemical examination confirmed a World Health Organization grade II extracranial meningioma. The patient recovered without complications. Postoperative magnetic resonance imaging showed no residual tumor, and adjuvant radiotherapy was not administered. Surveillance imaging every 6 months demonstrated no recurrence over 3.5 years. This case highlights the importance of including extracranial meningioma in the differential diagnosis of temporal masses and supports complete excision as effective management. A brief literature review is included.

A 43-year-old woman presented with bilateral lower extremity weakness due to an intradural extramedullary spinal cord tumor. Surgery revealed Ewing sarcoma, a rare presentation known as primary intradural extramedullary Ewing sarcoma (PIEES). Despite initial treatment with radiation and chemotherapy, tumor recurrence occurred after 17 months. Further interventions included additional surgery, radiation, and chemotherapy. The disease progressed to leptomeningeal metastases along the spinal cord, prompting various treatments including targeted spinal radiation and systemic therapies. Brain metastases subsequently developed, necessitating whole-brain radiation and intrathecal chemotherapy. This case highlights the aggressive nature of PIEES, its potential for widespread leptomeningeal metastasis, and the challenges in its management, underscoring the need for multidisciplinary approaches in treating this rare and aggressive malignancy.

Purpose: Considering the current lack of consensus on post–poly(adenosine diphosphate-ribose) polymerase inhibitor (PARPi) treatment strategies, this study aimed to evaluate the efficacy of subsequent therapy and compare the outcomes of regimes in patients with recurrent ovarian cancer after PARPi treatment. Materials and Methods: This multi-center retrospective cohort study analyzed data on patients diagnosed with ovarian cancer between January 2012 and June 2023 who had previously used PARPi after first- to fourth-line platinum-based chemotherapy. The primary endpoint was progression-free survival (PFS), which was the interval between recurrence after using PARPi and subsequent recurrence in the case of recurrence. Results: Of 318 patients, 147/318 (46.2%) recurred after the PARPi maintenance. Patients were categorized into groups based on subsequent therapy except non-treated (11/147, 7.5%): platinum-based chemotherapy (89/147, 60.5%), non-platinum-based chemotherapy (21/147, 14.3%), other treatments (26/147, 17.7%), and the median PFS (mPFS) for each group were 7.3, 4.8, and 11.4 months, respectively. Among the platinum-based chemotherapy group, the gemcitabine+carboplatin regimen demonstrated a longer mPFS (10.1 months) than the other regimens (6.6 months, p=0.019). In non-platinum-based chemotherapy, no statistically significant differences were observed among the regimens. And, in the other therapy group, where the proportion of patients with oligometastasis was as high as 88.5%, no significant differences were observed among the therapies, including other modalities. Conclusion In the subsequent chemotherapy of recurrent ovarian cancer after platinum-based chemotherapy and PARPi, the gemcitabine+carboplatin regimen demonstrated a potential to delay recurrence more effectively compared to other therapies.

Purpose: This study aimed to assess the efficacy and safety of first-line modified FOLFIRINOX in patients with advanced urachal cancer. Materials and Methods: The ULTIMA trial (NCT04611724) is a single-arm, open-label, multicenter phase II study evaluating modified FOLFIRINOX (oxaliplatin 85 mg/m2 over 2 hours, irinotecan 150 mg/m2 over 1.5 hours, leucovorin 400 mg/m2 over 2 hours, and 5-fluorouracil 2,400 mg/m2 over 46 hours) plus prophylactic pegteograstim in patients with recurrent or metastatic urachal cancer every 2 weeks for up to 12 cycles, or until disease progression or unacceptable toxicity. The primary endpoint was the overall response rate (ORR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), and the incidence of febrile neutropenia. Results: Between April 2021 and November 2023, 21 patients with advanced urachal cancer were enrolled across five cancer centers. The median age was 50 years (range, 28 to 68 years), with 15 male patients. The most common metastatic site was the lung (47.6%), followed by lymph nodes (38.1%) and peritoneal seeding (33.3%). Two patients and 11 patients achieved a complete and partial response, respectively, yielding an ORR of 61.9%. The study met its primary endpoint in the first stage. With a median follow-up of 23.3 months, the median PFS was 9.3 months (95% confidence interval [CI], 6.7 to 11.9), and the median OS was 19.7 months (95% CI, 14.3 to 25.1). The treatment regimen was well tolerated, with no unexpected adverse events, and no instances of febrile neutropenia or grade 4 adverse events. Conclusion In this preliminary analysis of the ULTIMA trial, Modified FOLFIRINOX demonstrated a promising ORR and PFS in patients with advanced urachal cancer. Completing the full study is essential to confirm the potential role of this regimen in the management of advanced urachal cancer.

Reconstructing Fournier’s gangrene is particularly challenging because it rapidly leads to soft tissue necrosis that requires extensive debridement. This often results in a large soft tissue defect with dead space due to structural irregularity. We report two cases of Fournier’s gangrene successfully reconstructed using a pedicled anterolateral thigh (ALT) flap with a chimeric pattern. A 61-year-old man with Fournier’s gangrene presented with extensive necrosis in the penoscrotal area. After radical debridement and infection control, the wound was reconstructed using a chimeric pattern pedicled ALT flap. The flap was composed of fasciocutaneous and muscle components supplied by branch vessels from the main pedicle. The fasciocutaneous component adequately resurfaced the defect, and the muscle component filled in the dead space between the two testes. A 58-year-old man with Fournier’s gangrene on the penoscrotal area also underwent reconstruction using the same method. In both cases, the flaps survived without any major complications and the reconstructions were successful with no recurrence of infection. When reconstructing Fournier’s gangrene, a trapezoidal-shaped dead space between the two testes is inevitable. Inadequate obliteration of this space may result in recurrent infection. An ALT flap with a chimeric pattern offers an adequate option for resurfacing and dead space obliteration.

Subarachnoid hemorrhage (SAH) is a stroke subtype with high mortality and poor functional outcomes. Prompt occlusion of a ruptured aneurysm at an early stage is crucial to prevent rebleeding, which can result in even higher mortality and more severe disabilities. The most critical initial decision in SAH management is the choice of treatment method with surgical clipping or endovascular coiling. We aimed to develop an evidence-based clinical guideline to select the optimal initial treatment in patients with SAH. We developed this guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted across four databases (MEDLINE, Embase, Cochrane, and KoreaMed) to answer two population, intervention, comparison, outcome questions comparing clipping and coiling. The risk of bias was assessed using ROB 2.0 and the Newcastle-Ottawa Scale. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagrams and meta-analyses were generated for functional outcome and mortality. We included six randomized control trials (RCTs) and 58 observational studies. Meta-analysis of RCTs showed that coiling improved functional outcomes compared to clipping (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.86–0.97). No significant mortality difference was observed in RCTs (OR, 1.38; 95% CI, 0.91–2.09), but non-RCTs favored clipping for reduced mortality (OR, 0.77; 95% CI, 0.69–0.86). However, it is difficult to generalize these findings to all clinical situations, as patients with SAH have a highly variable clinical course. Final treatment decision should be tailored to the individual patient’s status, including aneurysm location, morphology, and the expertise available at the treatment center. Such decisions are best made by specialists such as a board-certified physician and should be explained to the patient and their caregivers, along with the rationale for selecting the most appropriate treatment at the given hospital. Korea has many certified endovascular neurosurgeons, cerebrovascular surgeons, and certified cerebrovascular centers. Proper selection of the most suitable treatment method by certified physicians and centers would greatly benefit patient outcomes and healthcare professionals.

Accurate and early identification of stroke and large vessel occlusion (LVO) in emergency settings is essential for improving patient outcomes and ensuring the efficient allocation of medical resources. This clinical practice guideline systematically reviews domestic and international literature and conducts meta-analyses to evaluate the utility and diagnostic accuracy of stroke assessment tools used in prehospital emergency medical services (EMS). We developed a guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted to evaluate the usefulness of diagnostic EMS assessment tools for diagnosing stroke and LVO. Overall, 70 non-randomized control studies were selected for this study. A meta-analysis was conducted with a subgroup analysis to distinguish between patients with stroke and those with LVO. EMS tools demonstrated high sensitivity but low specificity for diagnosing stroke. In the prehospital setting, using validated EMS stroke assessment tools is recommended for the early identification of stroke and LVO. Upon hospital arrival, stroke specialists should conduct further evaluation and triage to confirm the diagnosis and guide appropriate management. Delays in diagnosing LVO are frequently unacceptable. While experts advocate for the use of EMS assessment tools to facilitate early identification of LVO, these tools alone lack adequate sensitivity. Therefore, further diagnostic evaluations and consultation with stroke specialists upon hospital arrival are recommended.

The mothership (MS) model, where patients are directly transferred to a thrombectomy-capable center, and the drip-and-ship (DS) model, where thrombolysis is initiated at the nearest primary stroke center before transfer for thrombectomy, are the primary transport modes for patients with stroke. We aimed to establish guidelines for selecting the appropriate transfer strategy based on emergent large vessel occlusion (LVO). We developed this guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted across four databases (MEDLINE, Embase, Cochrane, and KoreaMed) to answer three Population, Intervention, Comparison, and Outcome questions comparing MS and DS models. The risk of bias was assessed using the Newcastle-Ottawa Scale. Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagrams and meta-analyses were generated for functional outcomes, mortality, and successful recanalization. Twenty-six non-randomized controlled studies showed that the MS model improved good functional outcomes by approximately 14% compared with the DS model (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.00–1.30). Fifteen studies reported that mortality in the MS and DS models showed no significant differences (OR, 0.97; 95% CI, 0.84–1.11). Twenty-four studies revealed no significant difference in successful recanalization between the MS and DS models (OR, 0.87; 95% CI, 0.68–1.10). The MS model should be considered first to improve the functional outcome of patients with LVO. However, if thrombectomy cannot be performed immediately after thrombolysis, or if a thrombectomy-enabled hospital is not nearby, the DS model should be considered by stroke specialists depending on transportation time and regional factors. We suggest a mixed approach with the DS model based on specific circumstances or regions to ensure the optimum treatment of patients with acute ischemic stroke (AIS). Appropriate transport for patients with LVO improves the prognosis of AIS.

Objectives: This study evaluated the educational effectiveness of the Loving Life TokTok 65+, a suicide prevention gatekeeper education program for the elderly developed by the Jeju Special Self-Governing Province Mental Health Welfare Center. Methods: Community-dwelling adults aged ≥65 years (n=125) were assigned randomly to an intervention group (n=61) or a control group (n=64). The intervention group received the Loving Life TokTok 65+ program, while the control group received no education during the study period. The outcomes were assessed immediately before and after the intervention using validated self-report measures of gatekeeper behavior, preparedness to help, suicide prevention literacy, and attitudes toward suicide. Results: Post-intervention, the intervention group showed significant improvement in overall gatekeeper behavior (all p<0.001), particularly in readiness and self-efficacy, compared with the baseline, whereas the control group showed no significant change. Conclusion The Loving Life TokTok 65+ program effectively enhanced suicide-prevention–related behavioral competencies among the elderly.
