Background: Arthroscopic repair of bucket-handle meniscal tears (BHMTs) is technically challenging owing to the complexity of the tear patterns. Compared to simpler meniscal tears, BHMTs are associated with a higher failure rate and often require subsequent meniscectomy. This study aimed to assess clinical outcomes, failure rates, and risk factors for failure following primary arthroscopic repair of BHMTs. Methods: Seventy-four patients (mean age, 27.2 ± 11.2 years) who underwent arthroscopic BHMT repair were included (mean follow-up period, 60.2 ± 36.0 months). Analyzed risk factors included age, sex, body mass index, chronicity, laterality, tear zone, and concomitant anterior cruciate ligament reconstruction. Clinical failure was defined as the presence of clinical symptoms consistent with a meniscus tear and the need for subsequent surgery. The Kaplan-Meier method and log-rank test were performed to compare groups classified by postoperative meniscal healing status on magnetic resonance imaging (MRI) at a mean follow-up period of 7.30 ± 1.80 months. Clinical outcomes were assessed using the Tegner activity score, Lysholm knee score, and Hospital for Special Surgery (HSS) knee score. Results: The clinical failure rate was 14.9% (11 / 74). Six patients underwent subtotal meniscectomy, and 5 patients underwent partial meniscectomy. Red-white zone involvement was a significant risk factor for clinical failure (odds ratio, 6.182; 95% CI, 1.093–34.950; p = 0.039). Survival analysis based on postoperative MRI findings revealed a significant difference among 3 groups (p = 0.008): the completely healed group showed a 100% survival rate (20 / 20); the partially healed group, 80% (32 / 40); and the unhealed group, 0% (0 / 5). Patients with lateral BHMTs had a significantly higher rate of complete healing than those with medial BHMTs (46.4% vs. 18.9%; p = 0.014). At the final follow-up, the non-failure group demonstrated significantly higher Tegner activity (5.1 ± 1.2 vs. 4.4 ± 0.5; p = 0.038), Lysholm knee (87.7 ± 6.2 vs. 83.2 ± 3.1; p = 0.029), and HSS knee (93.9 ± 4.7 vs. 89.6 ± 3.0; p = 0.007) scores than the failure group. Conclusions BHMTs involving the red-white zone or located in the medial meniscus—particularly those showing inferior early postoperative MRI healing—should be closely monitored after surgery.

Background/Aims: Both endoscopic resection (ER) and transanal surgery (TAS) are minimally invasive treatment options that allow organ preservation in early rectal tumors. We conducted a meta-analysis to compare treatment outcomes between the 2 treatments. Methods: We searched all relevant studies published until January 2024 that examined the comparative outcomes between ER and TAS for rectal tumors, including adenoma, adenocarcinoma, and neuroendocrine tumor (NET). TAS included transanal excision, transanal endoscopic microsurgery, and transanal minimally invasive surgery. Results: Seventeen studies with a total of 1,569 patients were included in this meta-analysis. For adenoma/adenocarcinoma, the R0 resection rate did not differ between ER and TAS (risk ratio [RR], 0.99; 95% confidence interval [CI], 0.94–1.03). For NET, the R0 resection rate was lower in the ER group than in the TAS group (RR, 0.76; 95% CI, 0.68–0.84) and the procedure time for ER was shorter than that for TAS. For both adenoma/adenocarcinoma and NET, ER and TAS did not differ in terms of complication rates, additional surgery, and recurrence. Conclusions ER and TAS showed similar treatment outcomes for adenoma/adenocarcinoma. Considering that TAS typically incurs higher costs than ER, ER may be favored in the treatment of rectal adenoma/adenocarcinoma. For rectal NET, TAS showed a superior R0 resection rate than ER. However, given that TAS requires a long procedure time, expensive equipment, and complex manipulations, TAS may be considered selectively for large NETs with suspected deep tumorous infiltration.

Educational counseling is a fundamental component of tinnitus management; however, its structure, content, and clinical outcomes vary. This scoping review analyzed ten peer-reviewed studies to inform the development of standardized, evidence-based protocols. Three studies evaluated educational counseling alone, whereas seven combined it with other therapeutic approaches. Most interventions delivered key content during an initial session. Six studies employed individual face-to-face formats, whereas four compared delivery modes, including individual versus group or traditional versus technology-assisted methods. Counseling content was typically derived from expert consensus or prior research, and three studies explicitly described the theoretical rationales underlying their counseling frameworks. Core topics included auditory anatomy and tinnitus pathophysiology, although these topics were occasionally omitted from brief sessions. Nine studies presented practical management strategies, and five studies tailored content using individual hearing and tinnitus profiles. All studies used self-report measures, with the Tinnitus Handicap Inventory being the most common. Some studies reported improvements from counseling alone, whereas others showed outcome differences when counseling was combined with hearing aids or sound therapy, or delivered in alternative formats. This heterogeneity underscores the need for clearer and more standardized clinical protocols, as outcomes may vary depending on the content provided, patient characteristics, delivery method, patient’s understanding, and application of information.

Background: Laser procedures are integral to dermatologic practice, yet safety measures- particularly regarding ocular protection and plume control- are poorly studied in real-world settings. Objective: To evaluate current practices in eye protection, infection control, and occupational risk awareness among Korean dermatologists performing laser treatments. Methods: A cross-sectional survey was conducted among board-certified dermatologists at the 2024 Korean Society for Dermatologic Laser Surgery meeting. The questionnaire covered demographics, laser frequency, use of goggles and masks, infection control strategies, ophthalmologic monitoring, and history of warts or cancer. Results: Seventy-nine respondents completed the survey. All reported using protective goggles, but only 26.6% and 22.8% did so for CO 2 and erbium-doped yttrium aluminium garnet lasers, respectively. Only 24.1% underwent regular eye exams, and 13.9% reported eye conditions after starting laser practice. While 89.9% used masks, 40.8% used dental masks, which are inadequate for plume protection. Suction devices were used by 94.9%, though performance specifications were unclear. Warts were reported by 46.8% of respondents; two reported cancer diagnoses after initiating laser work. Conclusion Despite high overall adherence to basic safety practices, critical gaps remain. Our findings highlight the need for standardized guidelines and long-term occupational health monitoring to ensure safe laser practice.

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.

Osteoid osteoma accounts for approximately 10% of all benign bone tumors, but only approximately 4% of cases occur in the foot and ankle area. Periarticular osteoid osteoma frequently manifests with nonspecific clinical symptoms that mimic other conditions, potentially leading clinicians down a diagnostic side path and resulting in delayed or missed diagnoses compared to extra-articular osteoid osteoma. Although plain radiographs may show nonspecific findings, magnetic resonance imaging can detect bone marrow edema and surrounding soft tissue changes. Computed tomography is the most accurate modality for diagnosis. This paper reports the case of a 26-year-old female diagnosed with periarticular osteoid osteoma of the calcaneus and was treated with arthroscopic localized curettage at the author’s institution.

Purpose: This study was conducted to revise the Nutrition Quotient for Preschool children (NQ-P), a tool for evaluating the overall dietary quality and eating behavior among Korean preschool-aged children. Methods: At the first stage, 20 items for assessing dietary behavior were selected based on the previous NQ-P checklist, incorporating the results of the Seventh Korea National Health and Nutrition Examination Survey, national nutrition policies, dietary guidelines, and recent literature reviews. A pilot study was conducted with 100 preschool children residing in Seoul and Gyeonggi Province, using an 18-item checklist. After exploratory factor analysis and expert consultation, 15 items were finalized for use in nationwide survey checklists. The nationwide survey was conducted with a stratified sample of 800 preschool children across six metropolitan cities. Confirmatory factor analysis was used to revise the NQ-P 2021 and make it suitable for the structural equation model. Results: The NQ-P 2021 was developed using 15 checklist items organized into three factors:balance (7 items), moderation (4 items), and practice (4 items). The standardized path coefficients were used as item weights to determine the nutrition quotients. The weights of balance, moderation, and practice were 0.40, 0.15, and 0.45, respectively. In the nationwide survey, the mean NQ-P 2021 score was 59.67. The average scores for balance, moderation, and practice were 51.00, 62.45, and 66.46, respectively. Conclusion The revised NQ-P 2021 provides a validated and practical tool for assessing the dietary quality and eating behaviors of preschool children in Korea.

The Wikstroemia genus is highly regarded in traditional Asian medicine for its diverse therapeutic applications, including the treatment of inflammatory and infectious conditions. Among its members,Wikstroemia trichotoma (Thunb.) Makino remains a promising medicinal resource which is yet to be chemicallycharacterized. To ensure the chemical consistency of W. trichotoma, we developed and validated the first HPLC method for the simultaneous quantification of three major marker compounds: chlorogenic acid (1), miconioside B (2), and matteucinol 7-O-apiofuranosyl(1→6)-glucopyranoside (3). Chromatographic separation was achieved on a C18 column using a gradient elution system of 0.1% formic acid in water and 0.1% formic acid in acetonitrile. Detection was optimized using a photodiode array (PDA) detector at 280 and 325 nm, based on the absorption maxima of the markers. The method was validated in accordance with the International Council for Harmonisation (ICH) and the Ministry of Food and Drug Safety (MFDS) guidelines. The results demonstrated high linearity (r2 > 0.999), with limits of detection and quantitation ranging from 4.28–6.42 and 12.97–19.47 μg/ mL, respectively. Intra- and inter-day precision (% RSD ≤ 1.83%) and accuracy (recoveries of 92.5–101.7%) were within acceptable limits. Quantitative analysis revealed the contents of 1, 2, and 3 in the W. trichotoma extract to be 19.9, 139.8, and 264.9 mg/g, respectively. This study provides a reliable analytical framework for the standardization, quality control, and future pharmacological evaluation of W. trichotoma.

Purpose: Enhanced Recovery After Surgery (ERAS) protocols have demonstrated significant benefits, but their safety and effectiveness in high-risk patients remain unclear. This study evaluated clinical postoperative outcomes in elderly patients and those with comorbidities undergoing colon cancer surgery. Methods: This retrospective cohort study included 1,035 patients who underwent elective colon cancer surgery from 2017 to 2022. A standardized 25-element ERAS protocol was implemented across all groups. Patients were categorized into a control group (aged <70 years without comorbidities, n = 534) and high-risk groups including elderly patients (≥70 years, n = 312) and those with cardiac (n = 60), pulmonary (n = 81), renal (n = 24), or hepatic disease (n = 24). Results: ERAS compliance rates were significantly lower in all high-risk groups compared to controls (79.39% ± 10.9%), with renal disease patients showing the most pronounced reduction (69.69% ± 17.0%). Post-hoc analysis revealed that only renal disease patients demonstrated significantly higher complication rates (45.8% vs. 18.9%, P < 0.01). Despite lower compliance, multivariate analysis revealed ERAS compliance ≥70% as the strongest independent predictor of both length of stay (odds ratio [OR], 0.139; P < 0.001) and complications (OR, 0.298; P < 0.001), substantially outweighing patient risk factors. After adjusting for treatment factors, patient comorbidity groups showed no independent association with clinical outcomes. Conclusion ERAS protocols can be successfully implemented in high-risk patients with appropriate attention to compliance optimization. Treatment factors, particularly ERAS adherence, consistently outweigh patient risk factors in determining outcomes, and well-tailored ERAS implementation should be considered with high-risk patients for perioperative care.
