Three-dimensional (3D) graphics are used in the medical field, especially during surgery. Although 3D monitoring is useful for medical education, its effectiveness needs to be objectively evaluated. The aim of this study was to investigate the efficacy of 3D monitoring in the surgical education of medical students. ⋯ The use of 3D monitoring systems in medical education offers the advantage of stereopsis and contributes to surgical training. However, improvements are required to decrease eye exhaustion.

The aim of this study was to investigate the potential role of epidermal growth factor receptor (EGFR) protein expression in predicting the modality of treatment failure in glioblastoma (GB). ⋯ Different modality of recurrence related to EGFR expression in patients with GB envisages implication for target contouring of radiotherapy volumes and other therapeutic strategies.

Patients with laminar fractures have a higher chance of experiencing severe trauma and neurologic deficit. In previous studies, laminar fractures were divided into different types based on the axial plane of computed tomographic scans. No report described the morphology of vertical laminar fractures in the coronal plane. Furthermore, the correlation between a specific type of laminar fracture and the extent of severity of thoracolumbar (TL) burst fractures has rarely been mentioned. ⋯ The morphology of vertical laminar fractures as observed across multiple image planes was more complex and accurate than an analysis based solely on the axial plane. Different morphologies indicated differences in the severity of associated TL burst fractures. The laminar fracture in the coronal plane was associated with the severity of spinal injury.

To present an algorithm based on clinical and radiologic factors, including magnetic resonance imaging (MRI) perfusion/diffusion mismatch (PDM), for the indication of urgent cerebral bypass in patients with acute ischemic stroke. ⋯ Based on an algorithm indicating salvageable brain tissue, cerebral revascularization can be safely performed in an emergency setting in a highly selected group of patients with acute ischemic stroke with favorable clinical outcome.

Craniosynostosis is a complex disease once it involves deep anatomic perception, and a minor mistake during surgery can be fatal. The objective of this report is to present novel 3-dimensional-printed polyamide craniosynostosis models that can improve the understanding and treatment complex pathologies. ⋯ Simulation is becoming an essential part of medical education for surgical training and for improving surgical safety with adequate planning. This new polyamide craniosynostosis model allowed the surgeons to have realistic tactile feedback on manipulating a child's bone and permitted execution of the main procedures for anatomic correction. It is a low-cost model. Therefore our model is an excellent option for training purposes and is potentially a new important tool to improve the quality of the management of patients with craniosynostosis.
