In addition to well-known side effects such as rash, redness, and bone resorption, unexpected facial complications may occasionally occur several years after certain medical procedures. This report presents rare cases of orofacialsymptoms that developed as delayed responses to cosmetic filler injections. Three separate patients presented to theauthors’ institution with varying severities of orofacial symptoms. These symptoms, initially diagnosed clinically asinflammation or neoplasms of the parotid gland, were later identified through magnetic resonance imaging as diseases potentially associated with filler materials injected approximately 4-8 years earlier. The primary goal of this report was to inform specialists in the oral and maxillofacial field about the possibility of such complications, enabling them tomanage patient symptoms effectively and develop appropriate treatment strategies.

Background: Korea’s national suicide prevention strategies emphasize the role of local authorities. Evaluating local government performance helps determine whether suicide reduction goals are being met. This study assesses the performance of basic local government suicide prevention activities and explores their implications. Methods: Data were drawn from the 2023 Survey on Suicide Prevention Activities. Seventeen indicators, covering both process and outcome measures, were used to evaluate performance.A composite score (0–100) was calculated by weighting and summing the indicators, with weights based on average scores for each indicator. The 229 local governments were grouped into four categories by urbanization and population size: large Si (≥ 300,000 population), small Si (< 300,000), Gun, and Gu. The maximum–minimum (max–min) value ratio was used to examine composite score variation. Results: Among the 229 local governments, 29 were large Si areas, 49 small Si, 82 Gun, and 69 Gu. Significant disparities were found across several indicators, such as the operation of community suicide prevention centers, availability of mental health professionals, and allocated budgets. Composite scores were highest in large Si areas (59.8), followed by small Si (59.3), and Gu (57.9). The greatest variation was in Gun areas (max–min ratio: 2.6), suggesting inconsistent performance. Conclusion There are notable disparities in suicide prevention performance among Korea’s basic local governments. Customized strategies that reflect local capacities and contexts are essential to reduce these gaps and improve overall effectiveness.

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.

Purpose: This study evaluated the clinical outcomes and prognostic factors in patients with borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC) treated with upfront FOLFIRINOX followed by local-regional therapy (LRT), surgical resection (SR), and radiotherapy (RT). We aimed to identify specific patient subgroups for which RT may serve as a reasonable alternative to SR for local tumor control. Methods: We retrospectively analyzed 116 patients (SR group, n= 70; RT group, n= 46) at a single center between 2015 and 2020. Survival outcomes were compared based on LRT modalities, focusing on identifying subgroups in which RT provided an efficacy comparable to that of SR. Results: Among 116 patients, the SR group achieved a significantly higher 5-year overall survival (OS) than the RT group (27.1% vs. 8.7%, P< 0.0001), despite similar progression-free survival (P= 0.23). Significant prognostic factors for OS included carbohydrate antigen 19-9 (CA19-9) response in BRPC (P= 0.02) and radiologic partial response in LAPC (P= 0.05). Subgroup analysis revealed that, while SR provided a survival advantage in CA19-9 responders, no significant difference in OS was observed between SR and RT in CA19-9 non-responders (P= 0.37). Conclusion Although surgery remains the gold standard, RT may be considered a justifiable local alternative for CA19-9 non-responders and surgically ineligible patients with LAPC, yielding comparable outcomes in these specific, biologically unfavorable subgroups.

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.

Objective: This study aimed to describe the technique and outcomes of transforaminal endoscopic lumbar discectomy (TELD) for bilateral disc herniation. Methods: This retrospective review analyzed prospectively collected data. Patients who underwent single-level TELD for bilateral lumbar disc herniation with bilateral radiculopathy were included. The transforaminal entry approach utilized a 15° angle, compared to the conventional 30°. The disc space was approached from the side with the annular tear rather than the side with more severe symptoms. After introducing the working cannula and endoscope, the ipsilateral herniated disc was identified and removed. The approach angle was then adjusted to a more horizontal orientation to allow central decompression. The route to the contralateral herniated disc was identified, and the fragment was excised. Adequate decompression was confirmed by observing epidural pulsations, after which closure was performed. Operative time, length of hospital stay, patient-reported outcome measures, including the visual analogue scale (VAS) for back and leg pain and Oswestry Disability Index (ODI), and complications were analyzed. Results: Thirty-four patients were included, with a mean age of 41.6 years. The mean operative time was 58 minutes, and the mean hospital stay was 1.2 days. Significant postoperative improvement was observed in VAS back, VAS leg, and ODI scores. No intraoperative complications occurred. One patient (2.9%) developed postoperative dysesthesia, which resolved with conservative management. Another patient (2.9%) experienced reherniation, requiring revision endoscopic discectomy. Conclusion TELD for bilateral lumbar disc herniation with bilateral radiculopathy resulted in favorable clinical outcomes and minimal complications.

Objective: Unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) has emerged as an alternative to open TLIF. However, limited evidence is available regarding the application of 3-dimensional (3D)-printed titanium cages in UBE-TLIF. We aimed to compare the clinical outcomes and fusion rates of UBE-TLIF and open TLIF using 3D-printed titanium cages. Methods: We retrospectively reviewed patients who underwent single-level TLIF with 3D-printed titanium cages between 2021 and 2023. The inclusion criterion was degenerative lumbar stenosis, while the exclusion criteria were trauma, infection, and multilevel surgery. Clinical and radiologic outcomes were compared between the UBE-TLIF and open TLIF groups. Results: Twenty-one patients underwent UBE-TLIF, and 21 underwent open TLIF. The visual analogue scale (VAS) for back (p=0.987) and leg pain (p=0.731) did not significantly differ between the groups at 1-year follow-up. However, VAS back pain at postoperative day 2 was significantly lower in the UBE-TLIF group than in the open TLIF group (p<0.001). Solid fusion was achieved in 21 patients (100%) in the open TLIF group and in 20 (95.2%) in the UBE-TLIF group (p=1.000). In multivariable logistic regression analysis, body mass index was the only factor that exhibited a significant relationship (odds ratio [OR], 0.70; 95% confidence interval [CI], 0.53–0.92; p=0.011) with interbody fusion. In contrast, the surgical method (UBE vs. open TLIF) was not a significant factor (OR, 0.47; 95% CI, 0.10–2.21; p=0.337). Conclusion Using a 3D-printed titanium cage for UBE-TLIF may yield comparable fusion rates to those of open TLIF.

Legal risks and liability issues in medical practice serve as a primary catalyst for the current collapse of essential healthcare services in Korea. Currently, medical disputes in Korea are disproportionately focused on criminal prosecutions and high-damages civil litigation. This punitive approach fosters a culture of concealment, encourages defensive medicine, and accelerates the exodus of medical professionals from essential fields. Ultimately, this cycle deprives the system of opportunities for improvement and poses a significant threat to patient safety. In contrast, many advanced nations have adopted principles of “Just Culture” and “Safe Space,” prioritizing non-punitive reporting and systemic root-cause analysis over individual retribution. To address these issues, this paper proposes four key strategies: First, the establishment of an independent “Patient Safety Investigation Agency” to objectively investigate incidents and identify systemic flaws. Second, a transition from criminal punishment to licensing board-led management, focusing on re-education and counseling to maintain quality of care. Third, the enactment of “Apology Laws” to ensure that expressions of regret or apologies cannot be used as legal evidence of liability, thereby fostering trust and psychological recovery. Finally, the creation of a “Patient Safety Fund” to provide prompt and sufficient public compensation to victims regardless of proven negligence. In conclusion, it is imperative to shift the paradigm by defining medical accidents as “system failures” rather than individual faults. Strengthening the social safety net will encourage medical professionals to return to essential care and build a sustainable healthcare environment centered on patient safety.

Purpose: To determine the correlation between electroretinography (ERG) performed using a handheld ERG device equipped with skin electrodes and postoperative best-corrected visual acuity (BCVA) in patients with vitreous hemorrhage (VH) due to proliferative diabetic retinopathy (PDR). Methods: The medical records of patients who underwent vitrectomy for diabetic VH caused by PDR at our institution between July 1, 2017, and June 30, 2023, were reviewed retrospectively. We analyzed the correlation between preoperative ERG obtained using a handheld ERG device (RETeval), RETeval skin electrodes (Sensor Strips), and postoperative BCVA. Results: We evaluated the medical records of 70 eyes of 70 patients. The BCVA, which was measured in logMAR units, improved from 1.910 ± 0.504 preoperatively to 0.287 ± 0.225 postoperatively (p < 0.001). In the group that underwent panretinal photocoagulation before VH, the amplitudes of the b-wave in photopic ERG and 30-Hz flicker ERG were negatively correlated with the postoperative BCVA. The implicit times of the b-wave in photopic ERG and 30-Hz flicker ERG were positively correlated with the postoperative BCVA (p < 0.05). Conclusions Photopic ERG recorded using a handheld retinal ERG device equipped with skin electrodes can aid in predicting the visual prognosis in patients with severe VH caused by diabetes mellitus.
