Review Case Reports Meta Analysis
Systematic Review of Clinical, Radiologic, and Histologic Features of Benign Notochordal Cell Tumors: Implications for Patient Management.
There are no absolute defining criteria for benign notochordal cell tumors; the diagnosis is usually based on small size and the absence of aggressive features. Therefore, by definition, the diagnosis is subjective and usually determined by multidisciplinary consensus. A benign notochordal cell tumor should not grow during surveillance, and this may be used to confirm the diagnosis, but is a tautologic definition. Diagnostic ambiguity leads to uncertainty in management. If a tumor is a small chordoma then early surgery is likely to provide a better outcome. However, unnecessary treatment of a benign tumor may incur unjustified risk. ⋯ We suggest a clearer definition for a benign notochordal tumor and a management algorithm that incorporates a level of diagnostic uncertainty.

Review Meta Analysis
Four independent predictors of postoperative seizures after meningioma surgery: a meta-analysis.
Postoperative seizures after surgical resection of intracranial meningiomas will negatively affect the quality of life of patients. The aim of the present meta-analysis was to pool the current data and identify the independent predictors of postoperative seizures to better guide postoperative surveillance. ⋯ We identified 4 significant independent predictors of postoperative seizures after meningioma resection. These parameters should be considered in the follow-up of these patients to ensure optimal seizure surveillance, although ultimate validation by prospective studies is still required.

Spondylotic cervical myelopathy is a severe condition commonly affecting aging people. Although many investigations have been conducted, a consensus on the best surgical management is still missing. The aim of our study was to systematically review the pertinent literature and carry out a meta-analysis to compare the clinical and radiological outcome of the anterior cervical decompression and fusion (ACDF) and the posterior laminoplasty. ⋯ The results of this meta-analysis seem to suggest that ACDF should be preferred to the laminoplasty for the treatment of multilevel cervical myelopathy, although proper designed randomized controlled clinical trials are needed to further investigate this relevant ongoing issue.

The Michigan Spine Surgery Improvement Collaborative is a statewide multicenter quality improvement registry. Because missing data can affect registry results, we used MSSIC to find demographic and surgical characteristics that affect the completion of patient-reported outcomes (PROs) at 90 days and 1 year. ⋯ A multivariate analysis from a multicenter prospective database identified surgical factors that affect PRO follow-up, up to 1 year. This information can be helpful for imputing missing PRO data and could be used to strengthen data derived from large prospective databases.

Review Case Reports
One-stage surgical resection of giant intracranial arteriovenous malformations in selected patients: a novel diffusion tenser imaging score.
The effective treatment of giant cerebral arteriovenous malformations (gAVMs) is challenging. The aim of this study was to determine the risk factors for 1-stage resection of gAVM and develop a reliable indicator for patient selection. ⋯ One-stage surgical resection of gAVMs in patients with a low DTI score (0-2) seems to be feasible. The DTI score could be a reliable indicator for patient selection.
