Background: Distal radius fractures with complete intra-articular involvement and diaphyseal extension pose significant challenges for stable fixation. Treatment options vary, with no single method demonstrating superiority. This study analyzed the outcomes of fixing these type of fractures with volar locking plates, which are widely used worldwide, and the fracture length according to plate type to determine when an extra-long plate should be used. Methods: This retrospective review analyzed 89 consecutive patients surgically treated for Association of Osteosynthesis (AO) classification type C distal radius fractures with diaphyseal extension, excluding open fractures. The plate length was determined to be long enough accordingly to avoid placing screws in the fracture site. Radiographic evaluation and clinical outcomes were analyzed. Results: According to the AO system, C3 type fractures comprised 50%, C1 type 28%, and C2 type 22%. The average distance from the radiocarpal joint to the most proximal fracture line was 41.1 mm, with articular step off and gap of 1.7 mm and 3.7 mm, respectively. Concomitant distal ulna fractures were present in 81%. At final follow-up, the mean radial height was 10.9 mm, radial inclination was 22.8°, volar tilt was 5.7°, and ulnar variance was 0.6 mm. Fracture union occurred on average at 2.6 months. The average Disabilities of the Arm, Shoulder, and Hand score was 12.0 and the average Modified Mayo Wrist Score was 83.6. Regarding the average wrist range of motion, extension was 63.8°, flexion was 53.7°, ulnar deviation was 25.1°, and radial deviation was 16.7°. Complications included delayed wound healing in 3% and delayed union in 1 patient, who eventually achieved union at 10 months after surgery. APTUS Wrist Distal Radius Plates XL 2.5 and 2.4-mm Variable Angle LCP Two-Column Volar Distal Radius Plates showed a statistically significant difference in fracture length, with the former being longer than the latter (62 mm vs. 35 mm, p < 0.001). Conclusions If the fracture length from the articular surface to the diaphysis exceeds 60 mm, we recommend preparing an extralong distal radius plate. Volar plate fixation with appropriate length selection has yielded favorable functional outcomes and few minor complications in distal radius fractures with complete intra-articular involvement and diaphyseal extension.

Infants who are born between 24 hours and 1 year of age require extreme caution in their care due to their fragility. However, if there are multiple risk factors associated with the infant, caretaker, household, and surrounding circumstances, providing proper and appropriate care becomes problematic. This difficulty in caring for infants can contribute to abuse, neglect, or even death. This study investigates unexplained infant deaths that occur in the presence of multiple psychosocial risk factors. This study aimed to explore the relationship between various psychosocial risk factors and sudden, unexplained infant deaths. We examined nine cases from the autopsy archive of the National Forensic Service using a statistical approach. Among these cases, three were subject to legal action, while six were closed without further legal process. Although it was difficult to establish a clear relationship between death and abuse or neglect in the six cases, all were found to have experienced a harsh environment that was similar to abuse or neglect. We discuss the implications of our findings for understanding infant deaths and legal outcomes and propose a new framework to understand the deaths of infants.

Background and Objectives: The study sought to investigate the impact of early extracorporeal membrane oxygenation (ECMO) support before revascularization in patients with acute myocardial infarction (AMI) complicated by profound cardiogenic shock after resuscitated cardiac arrest. It is difficult to determine optimal timing of ECMO in patients with AMI complicated by profound cardiogenic shock after resuscitated cardiac arrest. Methods: Among 116,374 patients experiencing out-of-hospital cardiac arrest in South Korea, a total of 184 resuscitated patients with AMI complicated by profound cardiogenic shock, and who were treated successfully with percutaneous coronary intervention (PCI) and ECMO, were enrolled. Patients were divided into 2 groups according to the timing of ECMO: pre-PCI ECMO (n=117) and post-PCI ECMO (n=67). We compared 30-day mortality between the 2 groups. Results: In-hospital mortality was 78.8% in the entire study population and significantly lower in the pre-PCI ECMO group (73.5% vs. 88.1%, p=0.020). Thirty-day mortality was also lower in the pre-PCI ECMO group compared to the post-PCI ECMO group (74.4% vs.91.0%; adjusted hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.47–0.93; p=0.017). Shockable rhythm at the emergency room (HR, 0.57; 95% CI, 0.36–0.91; p=0.019) and successful therapeutic hypothermia (HR, 0.40; 95% CI, 0.23–0.69; p=0.001) were also associated with improved 30-day survival. Conclusions ECMO support before revascularization was associated with an improved short-term survival rate compared to ECMO after revascularization in patients with AMI complicated by profound cardiogenic shock after resuscitated cardiac arrest.

Background: Fibrous dysplasia (FD) is a rare, sporadic, and benign congenital condition in which normal cancellous bone is replaced by fibro-osseous tissue with immature osteogenesis. FD localized in the cranial and facial bones is called craniofacial fibrous dysplasia (CFD). Cystic degeneration in CFD cases is rare; cystic degeneration appearing in both the maxilla and the mandible FD lesion is even rarer. The aim of this article was to report a case of fibrous dysplasia of the mandible and maxilla complicated by nonspecific cystic degeneration.Case presentationA 30-year-old woman presented with a rare case of non-specific cystic degeneration in a mandible and maxilla FD lesion that occurred 11 years after surgery. She was diagnosed with polyostotic CFD and underwent maxillary and mandibular bone contouring. Cyst enucleation under general anesthesia was performed in the mandibular region due to pain and discomfort. Conclusions In cases involving non-aggressive and non-invasive FD cystic degeneration in focal areas, conservative treatment is recommended. However, if cystic degeneration of FD develops rapidly and causes discomfort, pain, or dysfunction, surgical treatment should be considered.

Background and objectives: A prolonged QTc interval is associated with an increased risk of a stroke or atrial fibrillation (AF). However, its direct causal relationship with AF associated a stroke has not been proven yet. To examine whether QTc interval is causally linked with risk of stroke in AF patients, we used the Mendelian randomization analysis. Subjects and methods: Among 2742 patients (73.6% male; 58.2 ± 11.0 years old; 69.5% with paroxysmal AF) who underwent AF catheter ablation, we analyzed 1766 patients who had preablation sinus rhythm electrocardiograms off antiarrhythmic drugs after excluding amiodarone users. Among them, 1213 subjects had genome-wide association study dataset analyzable for the Mendelian randomization. We explored the mechanistic relationships between QTc interval (ms) and the risk of a stroke by analyzing the Mendelian randomization (1213 subjects) after reviewing 35 genetic polymorphisms associated with the QTc in 31 European descent studies. Results: Among the patients in the higher quartile with a higher QTc, CHA2DS2-VASc score (p < 0.001), and age (p  < 0.001), the proportions of a prior stroke (p  < 0.001), females, heart failure, and persistent AF were significantly higher than in those in the lower quartile. The QTc was independently associated with the CHA2DS2-VASc score (β, 4.63E−5; 95% confidence interval, 3.57E−6–8.90E−5; p  = 0.034) and ischemic strokes (odds ratio, 1.01; 95% confidence interval, 1.00–1.01; p  = 0.027). However, there was no direct causal relationship between the QTc and CHA2DS2-VASc score or a prior stroke in either the one-sample or two-sample Mendelian randomizations. Conclusion The QTc was independently associated with the CHA2DS2-VASc score and strokes among the patients with AF who underwent catheter ablation, despite no genetically direct causal relationship.
