Background: Pediatric hospice and palliative care (PHPC) in South Korea remains in its early stages, influenced by cultural taboos surrounding death and its frequent association with geriatric care. While focusing on South Korean parents, this study also provides insights into cultural barriers common among Asian families with collectivist values. This qualitative study explored parental perceptions and cultural barriers to address the current evidence gap and to inform the development of culturally sensitive PHPC models in South Korea. Methods: Semi-structured interviews were conducted with 13 participants (12 parents and one patient) recruited from a tertiary hospital in South Korea. Participants were caregivers of children with serious chronic complex illnesses, including both malignant and non-malignant serious chronic or potentially life-limiting conditions. Data collection continued until pragmatic thematic saturation was achieved, and transcripts were analyzed using Krippendorff’s content analysis with an inductive coding approach. Results: Four overarching themes emerged: (1) cognitive and emotional barriers related to stigma and misconceptions; (2) perceived multidimensional benefits beyond clinical care; (3) family-centered support needs; and (4) strategies to optimize PHPC delivery. Many parents described experiences consistent with transgenerational guilt, reflecting feelings of guilt about passing an illness or vulnerability to their child, which emerged as a potential psychological barrier to PHPC engagement. Conclusion A substantial gap exists between recognition of PHPC and parental willingness to utilize services. Reframing PHPC as an early, concurrent support system led by healthcare professionals and supported by culturally sensitive communication may reduce parental guilt and improve access to family-centered palliative care services.

Autoimmune hemolytic anemia (AIHA) is a rare immune-mediated disorder in children that can present as primary or secondary to other diseases. Here, we report an unusual case of steroid-refractory warm AIHA in an 11-year-old girl whose condition was ultimately cured after removal of a benign ovarian tumor. Despite receiving multiple lines of therapy—including corticosteroids, rituximab, cyclosporine, sirolimus, and mycophenolate mofetil—the patient experienced recurrent hemolysis and steroid dependence for nearly four years. Abdominopelvic imaging performed to evaluate fever revealed bilateral ovarian cystic lesions, including a left-sided dermoid cyst. Surgical resection of the tumor led to complete and sustained hematologic remission, with normalization of hemoglobin, bilirubin, and reticulocyte counts, allowing discontinuation of all immunosuppressive agents. No recurrence of hemolysis was observed during 18 months of follow-up. This case highlights the potential for benign ovarian tumors to act as a rare secondary cause of AIHA through paraneoplastic or immune cross-reactive mechanisms. Awareness of such associations is crucial when evaluating pediatric patients with refractory or relapsing AIHA, as identification and removal of an occult tumor may achieve definitive resolution of hemolysis and avoid long-term immunosuppression.

Secondary rhabdoid tumors (RTs) with atypical teratoid/rhabdoid tumor-like features rarely arise from, or coexist with, pleomorphic xanthoastrocytomas (PXAs), and their clinicopathological and molecular characteristics remain poorly understood. We report a 17-year-old girl with a temporal lobe mass that, upon gross total resection, pathologically contained both RT and PXA components. Immunohistochemistry revealed loss of INI1 expression restricted to the RT component, while the PXA area retained INI1. Next-generation sequencing identified a shared BRAF::TRIM24 fusion and homozygous deletion of CDKN2A/2B in both components, indicating a shared clonal origin. Additionally, a germline ATM frameshift mutation (c.5288_5289insGA) was identified in both tumor components, making the first such report in central nervous system tumors. SMARCB1 loss was confined to the RT component, further supporting the hypotheses of clonal evolution and secondary transformation. Despite gross total resection, craniospinal irradiation, and chemotherapy, the patient developed rapid leptomeningeal dissemination and died 5 months after surgery. This case provides clinicopathological and molecular evidence for clonal evolution and secondary transformation of PXA into an RT. The presence of germline ATM mutation may have therapeutic and biological relevance. Further studies are required to clarify the pathogenesis and optimal management of these rare and aggressive tumors.

Background: Tibiotalocalcaneal (TTC) arthrodesis is a viable salvage option for failed total ankle arthroplasty (TAA), but it is typically a complex procedure associated with a high complication rate. This study analyzed outcomes of salvage TTC arthrodesis using a retrograde intramedullary (IM) nail without subtalar joint preparation after failed TAA. Methods: This study included 18 patients (18 ankles) who underwent TTC arthrodesis without subtalar joint preparation for failed TAA from July 2008 to March 2023 and were followed up for at least 2 years. Visual analog scale pain scores and Ankle Osteoarthritis Scale pain and disability scores were used to assess functional outcomes. Radiographic union, time to union, complications, and clinical success—defined as pain improvement without the need for revision surgery or amputation—were also evaluated. Results: The mean follow-up duration after TTC arthrodesis was 79.8 months (range, 26–199 months). Tibiotalar joint union was achieved in 13 ankles (72.2%) at a mean of 7.5 months after TTC arthrodesis. Subtalar joint union was achieved in 7 ankles (38.9%). All functional scores improved significantly from preoperatively to the last follow-up. The overall clinical success rate was 83.3% (15 ankles). Conclusions TTC arthrodesis using a retrograde IM nail without subtalar joint preparation produced favorable outcomes in patients with failed TAA. No complications associated with the subtalar joint were observed in any patient during follow-up. Therefore, TTC arthrodesis using a retrograde IM nail without subtalar joint preparation may be a considerable salvage option for failed TAA.

Janus kinase (JAK) inhibitors are an important treatment option for ulcerative colitis, providing rapid onset of action, oral administration, and efficacy even after biologic failure. The 3 approved agents—tofacitinib, filgotinib, and upadacitinib—differ in JAK isoform selectivity, leading to clinically meaningful differences in efficacy and safety. Evidence from network meta-analyses, clinical trials, and real-world studies consistently shows that upadacitinib provides the highest efficacy for induction and maintenance of remission, whereas filgotinib demonstrates the most favorable safety profile. The strong efficacy of upadacitinib and tofacitinib is particularly relevant in patients with severe disease, including acute severe ulcerative colitis, and upadacitinib maintains high efficacy regardless of prior advanced therapy exposure. JAK inhibitors also benefit extraintestinal manifestations. Although risks such as herpes zoster, serious infection, thromboembolism, and major cardiovascular events differ among agents, long-term data suggest generally acceptable safety when used appropriately. Intraclass JAK-to-JAK cycling is feasible, with about half of patients achieving steroid-free clinical remission in retrospective cohorts. Based on mechanistic, clinical, and real-world evidence, filgotinib may be a first-line option for patients with lower disease activity or when safety is a priority, whereas upadacitinib or tofacitinib may be preferred in higher disease activity. Strategically selecting agents may improve durability and outcomes.

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.

Purpose: This study investigated the nursing competency of graduates of 4-year college nursing programs following curriculum reforms. Methods: Participants were nurses with clinical experience ranging from six months to three years at tertiary and general hospitals. Proportional quota sampling was performed based on region and hospital type. Nursing competency among college graduates was examined using university graduates as the reference group; nursing managers evaluated the competencies of both groups. Results: First, the overall nursing competencies of college graduates (4.03±0.49) and university graduates (3.97±0.49) did not differ significantly (t=1.43, p=.154). Second, nursing managers’ evaluations indicated comparable nursing competencies of graduates from colleges (3.68±0.72) and university (3.54±0.64) (t=1.87, p=.062). Conclusion These results suggest that the reform of the 4-year nursing program at colleges successfully achieved its educational goals, equivalent to university training programs. These findings reflect positive educational outcomes achieved through changes in the academic system.

Objective: : A twig-like middle cerebral artery (T-MCA) is a rare condition characterized by steno-occlusion of the M1 segment of the middle cerebral artery (MCA) with nearby collateral arterial networks. Despite unclear pathophysiology, it is often classified as a congenital anomaly caused by failure of fusion of the plexiform MCA arterial plexus. We aimed to improve understanding of the pathophysiology of T-MCAs by analyzing incidental T-MCA findings and their natural history. Methods: : A retrospective chart review was performed between January 2011 and December 2023 at three medical centers treating both ischemic and hemorrhagic strokes. Patients with suspected MCA lesions were selected through radiology reports from computed tomography, magnetic resonance angiography, and digital subtraction imaging. Results: : We identified 51 T-MCA cases from a radiology report search spanning 13 years across three medical centers. The study included 9875 patients with ischemic stroke and 2097 with hemorrhagic stroke. Of the 51 T-MCA cases, incidental findings accounted for 25 (49.0%), ischemic stroke for 18 (35.3%), and hemorrhagic strokes accounted for eight cases (15.7%). T-MCA related ischemic and hemorrhagic strokes accounted for 0.18–0.38% of all strokes. The RNF213.R4810K mutation was identified in seven of 15 patients (46.7%) tested. We found three cases of a de-novo T-MCA that progressed from a normal MCA architecture. Conclusion : T-MCAs may represent an acquired secondary anomaly rather than a congenital lesion, followed by steno-occlusion of the focal MCA with new arterial network formation. Both Moyamoya angiopathy and chronic atherosclerosis likely contributed to disease progression. Formation of a microaneurysm, dilatation of the lenticulostriate artery, and hemodynamic stress can lead to stroke.

The maxillary anterior region is critical for esthetics and function, requiring precise analysis and restoration when damaged by trauma. This case report presents the restorative process using a digital workflow for a patient with anterior trauma. A 22-year-old female exhibited fractures and extrusive luxation of maxillary central incisors, diagnosed with pulp necrosis. After endodontic treatment, intraoral and facial scans were performed, and provisional and definitive restorations were digitally designed. Various shade-matching techniques were employed to achieve natural esthetics. The definitive prosthesis improved harmony between the incisal edge and lower lip, as well as tooth axis, length, and zenith position, fulfilling the patient’s esthetic demands. This case suggests that combining digital technology and gingivectomy with a minimally invasive approach enables esthetic and functional restoration of the maxillary anterior region.

Objective: Posterior interosseous nerve (PIN) syndrome (PINS) is a compressive neuropathy of the deep branch of the radial nerve that primarily presents with motor weakness of finger and thumb extension. Although some patients respond to conservative management, others develop persistent motor deficits requiring surgical decompression. This study aimed to evaluate the clinical outcomes of external neurolysis in patients with PINS presenting with refractory motor weakness. Methods: Seven patients with clinically diagnosed PINS who exhibited persistent motor weakness despite conservative treatment and subsequently underwent surgical decompression were retrospectively reviewed. Clinical characteristics, magnetic resonance imaging (MRI) findings, intraoperative compression sites, and postoperative motor recovery were analyzed. Motor strength was evaluated using the Medical Research Council grading system. Preoperative and postoperative motor strength grades were compared using the Wilcoxon signed-rank test. Results: The patients presented with progressive weakness of finger extension, resulting in impaired hand opening. MRI demonstrated denervation-related signal changes and atrophy in the affected muscles innervated by the PIN. Surgical exploration revealed compressive structures within the radial tunnel, most commonly at the arcade of Frohse. Significant improvement in motor strength was observed within 2 months postoperatively (thumb extension, p = 0.018; second digit extension, p = 0.011; third to fifth digit extension, p = 0.009). One patient experienced symptom recurrence approximately 6 months after the initial surgery and subsequently underwent revision decompression. Conclusion External neurolysis provides meaningful recovery of finger extension in patients with PINS presenting with refractory motor weakness. MRI may support the diagnosis by demonstrating denervation-related morphological changes in the affected muscles. Recurrence of PINS may occur even after initial recovery, highlighting the importance of careful postoperative follow-up.
