This study aimed to describe a facet-preserving modified transpedicular unilateral biportal endoscopic (UBE) approach for upwardly migrated thoracic disc herniation that allows safe decompression without spinal cord retraction or postoperative instability. Thoracic disc herniation is rare but often symptomatic, producing myelopathy that typically necessitates surgical intervention. Because of the spinal cord’s close proximity, traditional discectomy approaches carry a high risk of neural injury, and achieving complete disc removal without cord manipulation remains a significant surgical challenge. Although several techniques have been proposed, many are limited by the potential for incomplete decompression or iatrogenic instability. A facet-preserving modified transpedicular UBE approach may overcome these limitations by offering a minimally invasive surgical corridor while maintaining spinal stability. A 76-year-old woman presented with progressive bilateral lower extremity weakness and numbness over 6 months, with rapid deterioration during the past month. Magnetic resonance imaging (MRI) revealed an upwardly migrated thoracic disc herniation at T10–11 compressing the spinal cord. A UBE discectomy using a facet-preserving modified transpedicular approach was performed. The herniated fragment was completely removed without spinal cord retraction. Postoperatively, the patient demonstrated neurological improvement without complications. MRI confirmed complete decompression of the cord, and computed tomography verified preservation of the facet joint. This video article introduces the modified transpedicular UBE approach as a safe and precise minimally invasive technique for thoracic ventral pathologies. By enabling direct ventral decompression while preserving spinal stability, it broadens the scope of endoscopic spine surgery and warrants further clinical validation.

Purpose: Limited treatment options exist for patients with metastatic castration-resistant prostate cancer (mCRPC) after the failure of taxane-based chemotherapy and novel hormonal therapy. Here, we report the safety and efficacy of ifosfamide and mesna in patients with mCRPC after the failure of taxane-based chemotherapy and novel hormonal therapy (NCT06236789). Materials and Methods: Patients with histologically confirmed prostate cancer who had failed taxane-based chemotherapy and novel hormonal therapy received ifosfamide 2,500 mg/m2 and mesna 1,500 mg/m2 on days 1–3, repeated every 21 days. Safety, objective response rate, disease control rate, reduction in serum prostate-specific antigen (PSA) concentration by >50% (PSA50) or >90% (PSA90), radiographic progression-free survival (rPFS), and overall survival (OS) were analyzed. Results: A total of 47 patients with mCRPC were included in the study. The median number of lines of treatment was 5 (range, 3 to 7). All patients were previously administered docetaxel and novel hormonal therapies including abiraterone (51.1%) and/or enzalutamide (61.7%). Thirty-eight patients (80.9%) were administered cabazitaxel. The objective response and disease control rates were 21.3% and 80.9%, respectively. PSA50 and PSA90 were achieved in 31.9% and 10.6%, respectively. During a median follow-up duration of 54.3 months, rPFS and OS were 5.0 and 9.0 months, respectively. All the patients experienced treatment-related adverse events of any grades; however, no new safety signs were detected. Genomic biomarker analysis revealed that alterations in the TP53 pathway were associated with inferior rPFS and OS. Conclusion Ifosfamide and mesna showed appreciable efficacy and manageable safety profiles in heavily treated patients with mCRPC.

Prostate cancer (PCa) typically occurs in older adults and generally has a relatively long survival period, making it challenging to demonstrate the effectiveness of treatment. In 2012, medical guidelines recommending against PCa screening using prostate-specific antigen (PSA) became widespread, as randomized controlled trials had not consistently shown survival benefits.Current concepts: In South Korea, awareness of PCa has historically been very low, and the rate of PSA test screening has consequently been lower than that in other major developed countries. Additionally, PSA screening has tended to occur within a limited framework accessible only to individuals already aware of the test. Given that PCa is a high-risk cancer predominantly affecting older men in South Korea, unconditionally following medical guidelines from the 2010s that took a negative stance toward PSA screening may exacerbate health inequalities, increase metastatic cancer incidence, and elevate cancer-specific mortality, particularly in light of Korea’s rapidly aging population. Thus, recent shifts in clinical guidelines in the early 2020s, advocating the proactive implementation of PSA-based screening tests as announced by various countries, are significant. These shifts provide additional support for policy responses aligned with Korea’s epidemiological context. Discussion and conclusion: We advocate for increased public discourse on national PCa screening policies. Such policies should be rationally designed to reduce the incidence of high-risk PCa while minimizing the potential harms associated with overdiagnosis and overtreatment.

Background: With growing elderly populations, management of patients with acute stroke is increasingly important. In South Korea, the Acute Stroke Quality Assessment Program (ASQAP) has contributed to improving the quality of stroke care and practice behavior in healthcare institutions. While the mortality of hemorrhagic stroke remains high, there are only a few assessment indices associated with hemorrhagic stroke. Considering the need to develop assessment indices to improve the actual quality of care in the field of acute stroke treatment, this study aims to investigate the current status of human resources and practices related to the treatment of patients with acute stroke through a nationwide survey. Methods: For the healthcare institutions included in the Ninth ASQAP of the Health Insurance Review and Assessment Service (HIRA), data from January 2022 to December 2022 were collected through a survey on the current status and practice of healthcare providers related to the treatment of patients with acute stroke. The questionnaire consisted of 19 items, including six items on healthcare providers involved in stroke care and 10 items on the care of patients with acute stroke. Results: In the treatment of patients with hemorrhagic stroke among patients with acute stroke, neurosurgeons were the most common providers. The contribution of neurosurgeons in the treatment of ischemic stroke has also been found to be equivalent to that of neurologists. However, a number of institutions were found to be devoid of healthcare providers who perform definitive treatments, such as intra-arterial thrombectomy for patients with ischemic stroke or cerebral aneurysm clipping for subarachnoid hemorrhage. The intensity of the workload of healthcare providers involved in the care of patients with acute stroke, especially those involved in definitive treatment, was also found to be quite high. Conclusion Currently, there are almost no assessment indices specific to hemorrhagic stroke in the ASQAP for acute stroke. Furthermore, it does not reflect the reality of the healthcare providers and practices that provide definitive treatment for acute stroke. The findings of this study suggest the need for the development of appropriate assessment indices that reflect the realities of acute stroke care.

Background: Posterior reversible encephalopathy syndrome (PRES) is a rare complication of lung transplantation with poorly understood risk factors and clinical characteristics. This study aimed to examine the occurrence, risk factors, and clinical data of patients who developed PRES following lung transplantation. Methods: A retrospective analysis was conducted on 147 patients who underwent lung transplantation between February 2013 and December 2023. The patients were diagnosed with PRES based on the clinical symptoms and radiological findings. We compared the baseline characteristics and clinical information, including primary lung diseases and immunosuppressive therapy related to lung transplantation operations, between the PRES and non-PRES groups. Results: PRES manifested in 7.5% (n=11) of the patients who underwent lung transplantation, with a median onset of 15 days after operation. Seizures were identified as the predominant clinical manifestation (81.8%, n=9) in the group diagnosed with PRES. All patients diagnosed with PRES recovered fully. Patients with PRES were significantly associated with connective tissue disease-associated interstitial lung disease (45.5% vs. 18.4%, P=0.019, odds ratio=9.808; 95% CI, 1.064–90.386; P=0.044). Nonetheless, no significant variance was observed in the type of immunotherapy, such as the use of calcineurin inhibitors, blood pressure, or acute renal failure subsequent to lung transplantation. Conclusions PRES typically manifests shortly after lung transplantation, with seizures being the predominant initial symptom. The presence of preexisting connective tissue disease as the primary lung disease represents a significant risk factor for PRES following lung transplantation.
