The aim of this study was to determine the risk factors for postoperative infection after spinal surgery, in order to prevent its occurrence. We searched the Pubmed, Embase, and Cochrane library databases, and identified 25 case-control studies. ⋯ Our analyses suggest strategies to prevent surgical site infection. However, the results should be interpreted with caution because of heterogeneity amongst the included studies.

We present an updated overview of the literature regarding the management of flexion distraction injuries (FDI). FDI are unstable fractures of the thoracolumbar spine, which require surgical management by long segment open fusion or minimally invasive posterior fixation with pedicle screws. ⋯ Modern biomechanical studies have identified valuable prognostic indicators that may be elucidated from determining the mechanism of injury, including the degree of flexion and presence of compression at the time of injury. An improved understanding of FDI will contribute to more appropriate diagnoses and treatment of these fractures.

This study aims to investigate an association between ethanol exposure and in-hospital mortality among patients with isolated traumatic brain injury (iTBI). Ethanol exposure is associated with a substantially increased risk of sustaining an iTBI. However, once an iTBI has been sustained, it is unclear whether ethanol exposure is neuroprotective or harmful. ⋯ Ethanol exposure was not significantly associated with a change in the in-hospital mortality rate (adjusted odds ratio 1.01; 95% confidence interval 1.00-1.02; p=0.19). A substantial proportion of patients with iTBI were exposed to ethanol, but ethanol exposure was not independently associated with a change in mortality rate following iTBI. Any neuroprotection or harm from ethanol exposure was not conclusive, requiring further prospective trials.

We present a rare extramedullary ependymoma with diffuse spinal metastatic disease, and review the previous reports of extramedullary spinal ependymomas. Ependymomas are the most common intramedullary spinal cord tumor in adults. These tumors rarely present as extramedullary masses. ⋯ Only one tumor with an anaplastic grade resulted in metastatic disease, but without spinal recurrence. To our knowledge, this is the first report of an intradural, extramedullary spinal ependymoma with an anaplastic grade, presenting with concomitant diffuse, nodular leptomeningeal metastasis involving the upper cervical spine, thoracic spine, conus medullaris, and cauda equina. Similar to the treatment of intramedullary ependymomas with metastasis, this patient underwent an aggressive debulking procedure followed by radiation therapy to the entire neuroaxis.

Case Reports
Cervical CT scan-guided epidural blood patches for spontaneous intracranial hypotension.
We describe two patients with spontaneous intracranial hypotension (SIH), presenting with postural headache due to C1-C2 cerebrospinal fluid (CSF) leak. Both patients were refractory to lumbar epidural blood patching (EBP), and subsequently underwent successful CT scan-guided cervical EBP. SIH affects approximately 1 in 50,000 patients, with females more frequently affected. ⋯ However, in a select subgroup of patients, the symptoms are refractory to medical management and require more invasive therapies. In patients with cervical leaks, EBP in the cervical region is an effective management approach, either in close proximity to, or directly targeting a dural defect. CT scan-guided cervical EBP is an effective treatment approach in refractory SIH, and should be considered in those patients who are refractory to conservative management.
