Multicenter Study Observational Study
Surgery for herniated lumbar disc in daily tobacco smokers: A multicenter observational study.
To compare clinical outcomes at 1 year following single-level lumbar microdiscectomy in daily tobacco smokers and nonsmokers. ⋯ Nonsmokers reported a greater improvement in ODI at 1 year following microdiscectomy, and smokers were less likely to experience an MIC. Nonetheless, significant improvement was also found among smokers.

Case Reports
Orbital compartment syndrome after frontotemporal craniotomy: case report and review of literature.
Orbital compartment syndrome (OCS) is a rare condition characterized by increased intraorbital pressure and hypoperfusion of critical neural structures. It is usually associated with external ophthalmoplegia. We report a case of postoperative OCS following a frontotemporal craniotomy and review pertinent literature. ⋯ OCS is a rare ophthalmologic emergency characterized by an acute rise in orbital pressure and may result in complete irreversible blindness if not rapidly treated. The frontotemporal or "pterional" craniotomy exposure requires a myocutaneous flap to be retracted anteriorly and inferiorly near the orbit. There may be orbital compression due to this flap leading to potential harmful complications. Attention to factors such as direct ocular pressure from skin flaps, congestion from head positioning, and adequate intraoperative eye protection may reduce the risk or allow faster management.

Review Meta Analysis Comparative Study
Accuracy of Pedicle Screw Insertion among Three Image-Guided Navigation Systems: A Systematic Review and Meta-Analysis.
Many retrospective studies of pedicle screw placement have revealed that intraoperative navigation systems provide higher accuracy rates and safety than do free-hand techniques. The accuracy of various image-guided navigation systems has been studied; however, differences have not been well defined due to the lack of adequate evidence-based comparative studies. ⋯ Significant differences exist among CT Nav, 3D FluoroNav, and 2D FluoroNav. Our review suggests that 3D FluoroNav may be superior to the other 2 methods in reducing pedicle violation and that clinicians should consider 3D FluoroNav as a better choice.

Corticosteroids are routinely used to treat brain tumors. Although steroids have an immediate clinical benefit, their use can lead to a number of relevant complications, and a negative association with overall survival has been shown in glioblastoma (GBM) patients. There is no evidence in the literature regarding the ideal dose. We assessed the use of steroids in patients with GBM after resection surgery. ⋯ This study provides evidence for an inverse association between the lack of steroid dependency and mortality risk in patients whose steroid dosage was rapidly tapered after surgery. After resection, most patients can stop steroids within 2 weeks and finish radiotherapy without steroids.
