Moyamoya syndrome (MMS) is a subset of moyamoya disease (MMD) with a systemic comorbidity. Due to the lack of direct comparisons between various MMS subgroups and their MMD counterparts, we aimed to analyze differences in stroke-related outcomes between MMS subgroups and patients with MMD through propensity score matching (PSM). ⋯ Patients with MMS-SCD had significantly lower rates of acute ischemic stroke, hemorrhagic stroke, and TIA compared with patients with MMD only. Future research should consider the source of these differences in improving stroke prevention in patients with MMD.

Although the operating theatre offers unique didactic opportunities, it can be perceived as an uncomfortable environment by medical students due to the lack of theatre etiquette, time pressure and parallel work of different disciplines. We investigated whether virtual reality (VR) training can significantly reduce some of these fears and improve surgical education for medical students. ⋯ Routine VR use as part of clinical training could be beneficial in future medical education.

To comprehensively investigate the clinical and imaging features associated with the tumor growth rate (TGR) of pituitary neuroendocrine tumors (PitNETs). ⋯ The TGR of PitNETs is associated with age, T2 heterogeneity, and Knosp grade. Integrating these factors improves the accuracy of prediction for TGR. Therefore, understanding the TGR in PitNETs can provide valuable evidence for tailoring individualized treatment strategies for patients.

Fractures of the atlas are typically considered stable or unstable based on the integrity of the transverse ligament. Whereas stable Jefferson burst fractures can be treated nonoperatively, unstable fractures with disruption of the transverse ligament often require surgical intervention. Atlas osteosynthesis has been proposed as a motion-preserving alternative to atlantoaxial fusion. Intraoperative navigation may facilitate safe placement of C1 instrumentation. ⋯ Atlas osteosynthesis is an attractive motion-preserving approach to the treatment of unstable atlas fractures, avoiding the morbidity of atlantoaxial fusion. Classically reserved for Jefferson fractures with Dickman type II transverse ligament injury, atlas osteosynthesis may also be a viable option for type I transverse ligament injuries. Intraoperative navigation can be particularly useful for screw placement in the setting of traumatically distorted anatomy with lateral mass displacement.

To compare the clinical outcomes of unilateral biportal endoscopic discectomy (UBED) and percutaneous interlaminar endoscopic discectomy (PIED) for treating L5/S1 disc herniation. ⋯ UBED indicates similar short-term efficacy compared with PIED for treating L5/S1 disc herniation. No difference was found in facet joint preservation between the 2 groups. We believe the increased cost of UBED as the result of surgical consumables will decrease in the future.
