The integration of artificial intelligence (AI) into medical imaging has notably expanded its significance within urology. AI applications offer a broad spectrum of utilities in this domain, ranging from precise diagnosis achieved through image segmentation and anomaly detection to improved procedural assistance in biopsies and surgical interventions. Although challenges persist concerning data security, transparency, and integration into existing clinical workflows, extensive research has been conducted on AI-assisted imaging technologies while recognizing their potential to reshape urological practices. This review paper outlines current AI techniques employed for image analysis to offer an overview of the latest technological trends and applications in the field of urology.

Objectives: The Regional CardioCerebroVascular Center (RCCVC) project was initiated to improve clinical outcomes for patients with acute myocardial infarction or stroke in non-capital areas of Korea. The purpose of this study was to evaluate the outcomes and issues identified by the Busan RCCVC project in the treatment of ST-segment elevation myocardial infarction (STEMI). Methods: Among the patients who were registered in the Korean Registry of Acute Myocardial Infarction for the RCCVC project between 2007 and 2019, those who underwent percutaneous coronary intervention (PCI) for STEMI at the Busan RCCVC were selected, and their medical data were compared with a historical cohort. Results: In total, 1161 patients were selected for the analysis. Ten years after the implementation of the Busan RCCVC project, the median door-to-balloon time was reduced from 86 (interquartile range [IQR], 64-116) to 54 (IQR, 44-61) minutes, and the median symptom-to-balloon time was reduced from 256 (IQR, 180-407) to 189 (IQR, 118-305) minutes (p<0.001). Inversely, the false-positive PCI team activation rate increased from 0.6% to 21.4% (p<0.001). However, the 1-year cardiovascular death and major adverse cardiac event rates did not change. Even after 10 years, approximately 75% of the patients had a symptom-to-balloon time over 120 minutes, and approximately 50% of the patients underwent inter-hospital transfer for primary PCI. Conclusions A decade after the implementation of the Busan RCCVC project, although time parameters for early reperfusion therapy for STEMI improved, at the cost of an increased false-positive PCI team activation rate, survival outcomes were unchanged.

A traumatic sternal segment dislocation in children is very rare. Of the few cases reported, some recommended surgical treatment, while others reported good results by conservative treatment. Therefore, the treatment remains unclear. This paper reports a case of completely remodeled traumatic sternal segment dislocation in a 13-year-old boy treated by the restriction of activity and periodic observations.

Nora et al. first reported a bizarre parostealosteochondromatous proliferation (BPOP) as a small size bone malformation mainly in the foot and hand in April 1983 that was called Nora’s lesion or Nora’s disease. Nora’s disease is known for its low incidence and is characterized as a benign lesion, without a malignancy or metastasis with different histological, radiological, and clinical features from other common lesions. Several cases of Nora’s disease on the hand, foot, and long bone have been reported in Korea. This paper reports a case of BPOP of the proximal phalanx of the great toe.

Background and Objectives: In acute ST-segment elevation myocardial infarction (STEMI),on-site transmission of electrocardiogram (ECG) has been shown to reduce systemic timedelay to reperfusion and improve outcomes. However, it has not been adopted in communitybasedemergency transport system in Korea. Methods: Busan Regional Cardio-cerebrovascular Center and Busan Metropolitan City Fireand Safety Headquarters (BMFSH) jointly developed and conducted a pre-hospital ECGtransmission program. Seven tertiary hospitals and 22 safety stations of BMFSH participated.Systemic time delay to reperfusion of STEMI patients in the program was compared with thatof 95 patients transported by 119 emergency medical system (EMS) before the program wasimplemented. Results: During the study period, 289 ECG transmissions were made by 119 EMS personnel,executed within 5 minutes in 88.1% of cases. Of these, 42 ECGs were interpreted as STsegmentelevation. Final diagnosis of STEMI was made in 20 patients who underwent primarypercutaneous coronary intervention. With the program, systemic time delay to reperfusion wassignificantly reduced (median [interquartile range; IQR], 76.0 [62.2–98.7] vs. 90.0 [75.0–112.0],p<0.01). Significant reduction of door-to-balloon time was also observed (median [IQR], 45.0[34.0–69.5] vs. 58.0 [51.0–68.0], p=0.03). The proportion of patients with systemic time delayshorter than 90 minutes rose (51.6% vs. 75.0%, p=0.08) with pre-hospital ECG transmission. Conclusions We developed and implemented a community-based pre-hospital ECG transmission program for expeditious triage of STEMI patients. Significant reductions ofsystemic time delay and door-to-balloon time were observed. The expanded use of prehospitalECG transmission should be encouraged to realize the full potential of this program.

Purpose: This study investigated the relationship of the partnership between nurses and parents of hospitalized children with the quality of pediatric nursing care as perceived by pediatric nurses. Methods: A cross-sectional descriptive study was conducted among 90 nurses. The data collected were analyzed using the independent t-test and the Pearson correlation coefficient. Results: The level of partnership between nurses and parents showed significant differences by nurses’ age (t=2.22, p=.029) and marital status (t=2.54, p=.013). The quality of pediatric nursing care was found to significantly differ by the nurses’ age (t=2.62, p=.013), marital status (t=4.17, p<.001), whether nurses had children (t=2.53, p=.020), pediatric ward work experience (t=2.43, p=.020), and total work experience (t=2.51, p=.016). The level of partnership between nurses and parents was positively correlated with the quality of pediatric nursing care (r=.48, p<.001). Conclusion To improve the quality of nursing care for hospitalized children and their parents, it is important to consider the specific characteristics of pediatric nurses, whose clinical skills should be improved.

Schwannomas are benign neoplasms with a Schwann cell origin. A plexiform schwannoma is a rare variant of a schwannoma with a plexiform or multinodular growth pattern. The condition occurs mostly as a solitary lesion in the skin or subcutaneous tissue, or uncommonly located in the deep soft tissue. We report a rare case of recurred multiple plexiform schwannomas arising from the posterior tibial nerve and its branch, which was located in a deep anatomic location and accompanied by a bony deformity.

Most patients experience pain relief and functional improvement after arthroscopic rotator cuff repair. In some patients, however, symptoms still remain after surgery. Failed rotator cuff repair is a complex outcome of biological, technical, and traumatic factors. Moreover, re-tears might or might not be the main cause for patients with persistent pain after rotator cuff repair. Therefore, a thorough understanding of the patient's history, physical examination, and appropriate imaging studies will be needed to evaluate and manage these patients. The patient's age, functional requirement, quality of the rotator cuff, preoperative range of motion, quality of the deltoid, and glenohumeral arthritis are factors to consider before performing revisional rotator cuff repair. Preoperative patient education is as important as the surgical technique for successful revisional rotator cuff repair.

Capitellar osteochondral impaction fractures of the humerus are an uncommon injury and not encompassed by commonly used classification systems, such as that of Bryan and Morrey. Only a few cases of capitellar osteochondral impaction fractures have been reported. We report a case of a 53-year-old female with a capitellar osteochondral impaction fracture. The osteochondral fracture fragment of the capitellum was impacted and there was a step-off on the articular surface. Recovery of congruence in the capitellar articular surface was necessary. Satisfactory clinical and radiological results were obtained through the ‘lever arm’ reduction of the fracture fragment with a small osteotome and fixation with ‘raft’ K-wire.

PURPOSE: This study aimed to compare the quality of nursing care as perceived by registered nurses and mothers of hospitalized children in South Korea. METHODS: This was a descriptive study that recruited 70 mothers of hospitalized children and 70 nurses in pediatric units in university hospitals as participants. The quality of pediatric nursing care was measured using importance and performance scores for 19 items describing various elements of nursing care. The collected data were analyzed using descriptive statistics and the independent t-test. RESULTS: The hospitalized children mothers' mean importance scores were significantly higher than those of the nurses (t=2.94, p=.004). However, there were no significant differences in the mean performance scores of nurses and mothers (t=0.91, p=.363) or between nurses' and mothers' perceptions of quality of nursing care, with the exception of a significant difference for the quality of explanations (t=2.78, p=.006). The quality of explanations was assessed more positively by nurses than by mothers. CONCLUSION: This study suggests that when developing strategies to improve the quality of nursing care in pediatric wards, ensuring that pediatric nurses provide detailed explanations should be considered as a way to improve the quality of nursing care in pediatric units.
