Sanford Larson, MD, PhD: a pioneering neurosurgeon, scientist, and educator.
Dr. Sanford Larson, MD, PhD (1929-2012), was an influential figure in spinal neurosurgery. Dr. ⋯ His mentorship produced numerous leaders in organized neurosurgery and neurosurgical education, including Edward Benzel, MD, Dennis Maiman, MD, PhD, Joseph Cheng, MD, Shekar Kurpad, MD, PhD, and Christopher Wolfla, MD. Dr. Larson was a prominent leader in spinal neurosurgery and his legacy carries on today through his contributions to research, education, and surgical technique.

Randomized Controlled Trial Multicenter StudyUse of 5-ALA fluorescence-guided surgery versus white-light conventional microsurgery for the resection of newly diagnosed glioblastomas (RESECT study): a French multicenter randomized phase III study.
Only one phase III prospective randomized study, published in 2006, has assessed the performance of 5-aminolevulinic acid (5-ALA) fluorescence-guided surgery (FGS) for glioblastoma resection. The aim of the RESECT study was to compare the onco-functional results associated with 5-ALA fluorescence and with white-light conventional microsurgery in patients with glioblastoma managed according to the current standards of care. ⋯ The authors found that 5-ALA FGS is an easy-to-use, cost-effective, and minimally time-consuming technique that safely optimizes the extent of resection in patients harboring glioblastoma amenable to a large resection.

Meta AnalysisThe association of thromboembolic complications and the use of tranexamic acid during resection of intracranial meningiomas: systematic review and meta-analysis of randomized controlled trials.
Antifibrinolytics, such as tranexamic acid (TXA), have been shown to decrease intraoperative blood loss across multiple surgical disciplines. However, they carry the theoretical risk of thromboembolic events secondary to induced hypercoagulability. Therefore, the aim of this study was to systematically review the available literature and perform a meta-analysis on the use of TXA in meningioma resection to assess thromboembolic risks. ⋯ Current literature suggests that TXA is not associated with increased risk for VTE when administered during resection of intracranial meningioma. TXA appears to decrease intraoperative blood loss and allogeneic transfusion requirements during meningioma resection and thus may improve the safety of surgical management of this pathology.

Delayed nerve reconstruction for brachial plexus injuries: is the risk worth the reward?
Nerve reconstruction after 6 months of denervation time in brachial plexus injuries (BPIs) can be inconsistent. A dilemma exists when the use of critical donor nerves for nerve transfers may lead to unreliable outcomes that would waste the donor nerve. The purpose of this study was to evaluate the long-term outcomes of elbow and shoulder function in patients with BPIs receiving nerve reconstruction in the delayed setting (i.e., 6-12 months after injury). ⋯ Nerve reconstruction can effectively restore functional elbow flexion and acceptable shoulder abduction in non-pan-plexus patients with BPI in the delayed setting. However, neither acceptable elbow flexion nor shoulder abduction could be consistently achieved in pan-plexus BPI. Judicious use of the donor nerves in pan-plexus injuries is required, in addition to preserving a donor nerve for a backup plan such as free-functioning muscle transplantation or tendon transfers.

Clinical outcomes after MRI connectivity-guided radiofrequency thalamotomy for tremor.
Radiofrequency thalamotomy (RF-T) is an established treatment for refractory tremor. It is unclear whether connectivity-guided targeting strategies could further augment outcomes. The aim of this study was to evaluate the efficacy and safety of MRI connectivity-guided RF-T in severe tremor. ⋯ RF-T guided by connectivity-derived segmentation is a safe and effective option for severe tremor in both PD and ET.
