Significant care continuum delays between acute traumatic brain injury (TBI) and definitive surgery are associated with poor outcomes. Use of the "3 delays" model to evaluate TBI outcomes in low- and middle-income countries has not been performed. ⋯ Delays for mild and moderate TBI patients were associated with mortality, suggesting that quality improvement interventions could target current triage practices. Future research should aim to understand the contributors to delays along the care continuum, opportunities for more effective resource allocation, and the need to improve prehospital logistical referral systems.

The optimal observation interval after the radiosurgical treatment of a sporadic vestibular schwannoma, prior to salvage intervention, is unknown. ⋯ Tumor enlargement within ∼3.5 yr of treatment should not be used as a sole criterion for salvage treatment. Patient symptoms and tumor size must be considered, and giving tumors a chance to regress before opting for salvage treatment may be worthwhile.

Radiological evaluation of traumatic thoracolumbar fractures is used to classify the injury and determine the optimal treatment plan. Currently, there remains a lack of consensus regarding appropriate radiological protocol. Most clinicians use a combination of plain radiographs, 3-dimensional computed tomography with reconstructions, and magnetic resonance imaging (MRI). ⋯ Due to a paucity of published studies, there is insufficient evidence that radiographic findings can be used as predictors of clinical outcomes in thoracolumbar fractures.

Focused ultrasound thalamotomy (FUS-T) was recently approved for the treatment of refractory essential tremor (ET). Despite its noninvasive approach, FUS-T reinitiated concerns about the adverse effects and long-term efficacy after lesioning. ⋯ This is the first report of prospective VIM targeting with tractography for FUS-T. These results suggest that tractography-guided targeting is safe and has satisfactory short-term clinical outcomes.

The thoracic and lumbar ("thoracolumbar") spine are the most commonly injured region of the spine in blunt trauma. Trauma of the thoracolumbar spine is frequently associated with spinal cord injury and other visceral and bony injuries. Prolonged pain and disability after thoracolumbar trauma present a significant burden on patients and society. ⋯ The available evidence for the evaluation and treatment of patients with thoracolumbar spine injuries demonstrates considerable heterogeneity and highly variable degrees of quality. However, the workgroup was able to formulate a number of key recommendations to guide clinical practice. Further research is needed to counter the relative paucity of evidence that specifically pertains to patients with only thoracolumbar spine injuries.
