Review Meta Analysis
Percutaneous Endoscopic Lumbar Discectomy for L5S1 Lumbar Disc Herniation Using a Transforaminal Approach Versus an Interlaminar Approach: A Systematic Review and Meta-Analysis.
Several studies have compared the clinical efficacy of percutaneous endoscopic lumbar discectomy for L5-S1 lumbar disc herniation (LDH) using a transforaminal approach with an interlaminar approach, but with contradictory results. The aim of this study was to explore the comparison of efficacy and safety between percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) for L5-S1 LDH. ⋯ PETD had comparable clinical efficacy and safety compared with PEID; however, PEID was superior to PETD regarding fluoroscopy times and operative time. Therefore, PEID might be a better surgical procedure for L5S1 LDH.

Review Case Reports
Primary Intracranial Leiomyosarcoma with Intratumoral Hemorrhage: Case Report and Review of Literature.
Primary intracranial leiomyosarcoma is a very rare occurrence, and primary leiomyosarcoma with intratumoral hemorrhage has not been described previously. We present a case of a rapidly enlarging primary intracranial leiomyosarcoma with intratumoral hemorrhage. ⋯ To the best our knowledge, this is the first report of primary intracranial leiomyosarcoma with intratumoral hemorrhage.

Multicenter Study
Technique of Whole-Sellar Stereotactic Radiosurgery for Cushing's Disease: Results from a Multicenter, International Cohort Study.
Stereotactic radiosurgery (SRS) is used to manage patients with Cushing disease (CD) who have failed surgical/medical management. Because many patients with recurrent/persistent CD lack an identifiable adenoma on neuroimaging, whole-sellar SRS has been increasingly used. Thus, we sought to define the outcomes of patients undergoing whole-sellar SRS. ⋯ Whole-sellar GKRS is effective in controlling CD when an adenoma is not clearly defined on imaging or when an invasive adenoma is suspected at the time of initial surgery. Patients who undergo whole-sellar SRS have outcomes and rates of new pituitary hormone deficiency similar to those of patients who undergo discrete adenoma-targeted GKRS.

Review Case Reports
Surgical Treatment for Odontoid Fractures in Patients with Long-Standing Ankylosing Spondylitis: A Report of 3 Cases and Review of the Literature.
Ankylosing spondylitis (AS) is classified as a chronic inflammatory seronegative rheumatic arthritis. Patients with AS are more likely to sustain a fracture of the cervical spine compared with the general population. Most fractures occur in the lower cervical spine and manifest at the level of the intervertebral disc. There have been few reports about the surgical treatment for upper cervical spine fractures in patients with AS, especially odontoid fractures. We present 3 cases of odontoid fracture in patients with long-standing AS. ⋯ Odontoid fracture with atlantoaxial dislocation in patients with long-standing AS is uncommon. Clinicians must be cautious in assessing such patients with any episode of trauma. Computed tomography and magnetic resonance imaging can be helpful in demonstrating occult odontoid fractures. Posterior occipitocervical fusion with internal fixation may benefit these patients, although at the cost of sacrificing the last motion segment.
