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: Several types of dermal fillers have been recently introduced and used for penile augmentation (PA). However, few studies have compared outcomes after the injection of different fillers. This study aimed to compare the clinical outcomes of hyaluronic acid (HLA), polylactic acid (PLA), and polymethyl methacrylate (PMA) filler injections, which are the most commonly used for aesthetic purposes. Materials and Methods: This prospective study was conducted for 24 weeks after a filler injection by a surgeon between March 2017 and December 2021. Healthy adult men complaining of small penis were enrolled. Penile girth, satisfaction, and injection-associated adverse events (AEs) were assessed at baseline and 4, 12, and 24 weeks after injection. Results: Of the 301 men who received filler injections, 125, 134, and 42 received HLA, PLA, and PMA fillers, respectively. The augmentation effect was in the order of PMA, HLA, and PLA, respectively, at 24 weeks (PMA vs. HLA, p<0.001; HLA vs. PLA, p=0.006). Satisfaction levels increased significantly at 24 weeks in all groups (each with p<0.001). However, the increase in satisfaction levels was smaller in the PMA group (PMA vs. HLA or PLA, p<0.05, for both penile appearance and sexual life). No serious or systemic AEs were recorded. Filler injection-associated local AEs in the HLA, PLA, and PMA groups occurred in 9 (7.2%), 16 (11.9%), and 6 (14.3%) men, respectively. There was no significant difference in AEs among the groups (p=0.299). Conclusions The augmentative effect was greater in the PMA group than in the HLA and PLA groups, whereas the increase in satisfaction levels was smaller in the PMA group. Our study demonstrated the clinical course of different types of fillers and suggests that the filler type should be selected after detailed counseling considering individual characteristics and preferences.

Background: This study aimed to report the radiological outcomes and risk factors for malalignment of fractures in the distal onefourth of the tibia treated with intramedullary nailing via the infrapatellar approach. Methods: This study retrospectively analyzed 60 patients (37 men and 23 women; mean age, 45.4 years) who had distal onefourth tibial fractures and were treated with intramedullary nailing using the infrapatellar approach. These patients were treated between January 2009 and December 2021, with a minimum follow-up of 1 year. Fractures were classified according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association system: 25 were type 42A, 30 were type 42B, and 5 were type 43A. Radiographic outcomes focused on bone union and malalignment, defined as a valgus deviation greater than 5° compared to the unaffected side. Potential risk factors for malalignment, including open fractures (9 cases, 15%), distal tibial extension (20 cases, 33%), and distal fibular fractures (24 cases, 40%), were documented. Results: Bone union was achieved in all cases, with an average duration of 3.2 months (range, 3–5 months). No cases of postoperative wound infection or neurovascular damage were observed. The average coronal plane malalignment was 2.6° of valgus (range, 0°–9.3°), with significant malalignment (over 5°) occurring in 5 patients (8.3%). Comparison of the malalignment (n = 5) and normal (n = 55) groups showed a statistically significant difference in distal bone fragment length (average, 66.5 mm vs. 77.2 mm;p = 0.008) but no significant differences in other variables. A change-point analysis revealed that cases with a primary fracture line < 65 mm showed 4.5° of coronal malalignment, while those with > 65 mm showed 2.3°; the difference was statistically significant (p = 0.01). Conclusions Intramedullary nailing using the infrapatellar approach for distal one-fourth tibial fractures results in successful bone union with a low incidence of valgus malalignment. However, careful attention is necessary to prevent angular deformities, especially when the distal fragment is short.
