Review Meta Analysis
Unruptured paraclinoid aneurysm treatment effects on visual function: a systematic review and meta-analysis.
Postoperative visual outcomes following repair of unruptured paraclinoid aneurysms (UPAs) are not well defined. We aim to investigate the influence of treatment modality on visual function. ⋯ In patients with normal vision undergoing repairs for UPAs, there is a positive correlation between visual outcomes and endovascular treatments. When visual compromise is present, surgery provided modest advantage in visual recovery. However, definitive conclusions were not possible due to data heterogeneity.

Despite studies showing a positive correlation between type 2 diabetes mellitus (DM2), a modifiable risk factor, and various cancer types, the link remains controversial in the setting of glioblastoma multiforme (GBM). In this study, we assessed whether DM2 and DM2-associated factors were associated with a higher risk of developing GBM and also determined if DM2 affected the survival of patients with GBM. ⋯ DM2, hyperlipidemia, and obesity were not associated with increased risk of developing GBM, and DM2 itself does not seem to influence survival among these patients. This finding might be related to good glycemic control in this cohort. Survey of the literature consistently shows that hyperglycemia is associated with poorer survival. Our findings suggest that rather than the presence or absence of DM2, glycemic control seems to be more important in the survival of patients with GBM, which warrants future investigation.

In multilevel degenerative conditions posterior approaches are often preferred, but anterior approaches provide comparable clinical results and better alignment. Anterior plating entails higher rates of soft tissue injuries and dysphagia, particularly in multilevel cases. This study evaluates efficacy and safety of zero-profile devices in 3- and 4-level anterior cervical diskectomy and fusion, analyzing patients' clinical and radiologic long-term outcomes. ⋯ Anterior cervical diskectomy and fusion with a zero-profile device is effective and safe for 3- and 4-level cervical spondylotic myeloradiculopathy. It allows to restore cervical lordosis and achieve long-term satisfactory clinical outcome.

Review Case Reports
Iatrogenic vertebral artery injury during anterior cervical spine surgery: A systematic review.
Iatrogenic vertebral artery injury (VAI) during anterior cervical surgery is rare but potentially catastrophic. ⋯ Extensive lateral decompression, loss of landmarks, and anatomic variations or pathologic status of VA increased VAI risk. Evaluation of collateral vessels before definitive treatment helped determine appropriate management and avoid neurologic sequelae. Tamponade was not recommended as definitive treatment. Meticulous preoperative evaluation, cautious intraoperative manipulation, and real-time radiographic guidance reduced VAI risk.
