Purpose Of Review: Postoperative pain (POP) is among the most unpleasant experiences that patients face after surgery. Interest in and use of N-methyl-D-aspartate (NMDA) receptor antagonists for the management of POP has increased over the years with ketamine being the most popular drug of this class.
Recent Findings: Several randomized controlled trials found that the use of ketamine either alone or in combination with other medications leads to decreased postoperative pain and opioid consumption. However, there are other studies that have not found these benefits. The results as of now suggest that the role of intraoperative ketamine in postoperative pain control varies among different operative procedures. While some studies have shown promise in ketamine's potential use as a postoperative analgesic, there is still a great deal of proposed research and randomized controlled trials needed to deduce the most efficacious and tolerable form and dose of ketamine.

Awake, endoscopic lumbar interbody spinal fusion: 10 years of experience with the first 400 cases.
J Neurosurg Spine
January 2025
2Anesthesiology, University of Miami Miller School of Medicine, Miami, Florida.
Objective: Awake, endoscopic spinal fusion has been utilized as an ultra-minimally invasive surgery technique to accomplish the goals of spinal fixation, fusion, and disc height restoration. While many techniques exist for this approach, this series represents a single institution's experience with a large cohort and the evolution of this method.
Methods: The medical records of a consecutive series of 400 patients treated over a 10-year period were retrospectively reviewed.
Patient-reported outcome trajectories the first 24 months after surgery for cervical spondylotic myelopathy: a Quality Outcomes Database study.
J Neurosurg Spine
January 2025
1Neuroscience Institute, Carolina Neurosurgery & Spine Associates, Carolinas Healthcare System, Charlotte, North Carolina.
Objective: Cervical spondylotic myelopathy (CSM) shows varying levels of improvement after surgical treatment. While some patients improve soon after surgery, others may take months to years to show any signs of improvement. The goal of this study was to evaluate postoperative improvement, patient-reported outcomes, and patient satisfaction up to 2 years after surgical treatment for CSM, which will help optimize the current treatment strategies and effectively manage patient expectations.

Medicine (Baltimore)
January 2025
Department of Pathology, Keck School of Medicine, University of Southern California, Los Angeles, CA.
Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Rationale: Ependymomas are commonly prevalent intramedullary neoplasms in adults, with hardly any cases of exophytic extramedullary ependymoma being reported. Meningiomas, on the contrary, are one of the most common intradural extramedullary (IDEM) tumors. However, the occurrence of both IDEM tumors simultaneously is extremely rare.
