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.

Purpose: Osteosynthesis of a clavicular fracture can obtain good clinical results even with conservative treatment. The development of surgical techniques and improvements in internal fixation have led to the use of metal plates and screws. Although there are intramedullary nails or minimally invasive plate osteosynthesis that can reduce soft tissue damage, these techniques are not used often because most require a skin incision about the length of the metal plate to be inserted. This study compared the postoperative pain to determine the appropriate injection depth. Materials and Methods: A prospective, single-institute, single-blind, randomized study was designed. The patients in the study had clavicular fractures and who underwent the removal of implant. The patients judged to have difficulty indicating pain were excluded.Ropivacaine was injected between plate fixation and muscle suturing. The visual analog scale (VAS) pain score, patient-controlled analgesia (PCA) use, and additional pain medication usage were measured after surgery and every 4 hours. Results: Thirty-four clavicle shaft fracture patients were classified into 16 patients in the subcutaneous injection group and 18 in the muscle injection group. Seventeen implant removal patients were divided into eight patients in the subcutaneous injection group and another nine in the muscle injection group. In the fracture group, the mean VAS for the subcutaneous injection group was 4.20±2.68 immediately after surgery, 4.47±1.85 at 4 hours, 1.93±1.44 at 24 hours, and 1.60±1.35 at 48 hours. The mean VAS for the muscle injection group was 4.23±1.59 immediately after surgery, 3.00±1.47 at 4 hours, 1.69±1.03 at 24 hours, and 1.31±1.11 at 48 hours; the mean VAS score was not statistically significant in the two groups (p=0.332). In the implant removal group, the mean VAS for the subcutaneous injection group was 4.75±1.58 immediately after surgery, 3.75±1.04 at 4 hours, 1.75±0.89 at 24 hours, and 1.75±0.89 at 48 hours. The mean VAS for the muscle injection group was 3.78±1.20 immediately after surgery, 3.22±0.83 at 4 hours, 1.89±1.17 at 24 hours, and 1.11±1.01 at 48 hours; the mean VAS score was not statistically significant in the two groups (p=0.181). Conclusion The postoperative VAS pain score and PCA usage were not statistically significant regardless of the ropivacaine injection site in clavicular surgery, but each group had significantly different VAS pain scores and PCA usage according to time after surgery. In addition, the muscle injection group tended to have a lower average VAS than the subcutaneous injection group in the implant removal patient group.

Background: Acellular dermal matrices (ADMs) have shown promise in promoting tissue regeneration; however, their integration in challenging cases with limited vertical-axis neovascularization remains difficult. This study investigates whether clinically meaningful transverse-axis neovascularization is identified in ADM engraftment and whether this can be further accelerated by platelet-rich plasma (PRP). Methods: ADM and PRP-soaked ADM were implanted into New Zealand rabbits, and histological analysis was performed at different periods to compare neovascularization. Results: Histological analysis revealed that among 32 biopsy sites, there was transverse-axis neovascularization with an average length of 606.89 μm. When divided into two groups for assessing the impact of PRP on transverse-axis neovascularization, the extent of such neovascularization was measured as 582.99 μm in the control group and 630.79 μm in the experimental group. However, there was no statistically significant difference between the two groups (P=0.693). Conclusion The results of the present study indicate that achieving meaningful transverse-axis neovascularization in implanted ADMs remains a challenge, warranting further investigation into ADM structure and vertical-axis neovascularization.

Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.

Background: The PLASMIC score is a convenient tool for predicting ADAMTS13 activity of ＜10%.Lactate dehydrogenase (LDH) is widely used as a marker of haemolysis in thrombotic thrombocytopenic purpura (TTP) monitoring, and could be used as a replacement marker for lysis. We aimed to validate the PLASMIC score in a multi-centre Asia Pacific region, and to explore whether LDH could be used as a replacement marker for lysis. Methods: Records of patients with thrombotic microangiopathy (TMA) were reviewed. Patients’ ADAMTS13 activity levels were obtained, along with clinical/laboratory findings relevant to the PLASMIC score. Both PLASMIC scores and PLASMIC-LDH scores, in which LDH replaced traditional lysis markers, were calculated. We generated a receiver operator characteristics (ROC) curve and compared the area under the curve values (AUC) to determine the predictive ability of each score. Results: 46 patients fulfilled the inclusion criteria, of which 34 had ADAMTS13 activity levels of ＜10%. When the patients were divided into intermediate-to-high risk (scores 5‒7) and low risk (scores 0‒4), the PLASMIC score showed a sensitivity of 97.1% and specificity of 58.3%, with a positive predictive value (PPV) of 86.8% and negative predictive value (NPV) of 87.5%. The PLASMIC-LDH score had a sensitivity of 97.1% and specificity of 33.3%, with a PPV of 80.5% and NPV of 80.0%. Conclusion Our study validated the utility of the PLASMIC score, and demonstrated PLASMIC-LDH as a reasonable alternative in the absence of traditional lysis markers, to help identify high-risk patients for treatment via plasma exchange.
