Multicenter Study
Stereotactic Radiosurgery for Acromegaly: An International Multicenter Retrospective Cohort Study.
Stereotactic radiosurgery (SRS) is a treatment option for persistent or recurrent acromegaly secondary to a growth hormone secreting pituitary adenoma, but its efficacy is inadequately defined. ⋯ SRS is a definitive treatment option for patients with persistent or recurrent acromegaly after surgical resection. There appears to be a statistical association between the cessation of IGF-1 lowering medications prior to SRS and durable remission.

Randomized Controlled Trial Multicenter Study Comparative Study
Symptomatic Adjacent Level Disease Requiring Surgery: Analysis of 10-Year Results From a Prospective, Randomized, Clinical Trial Comparing Cervical Disc Arthroplasty to Anterior Cervical Fusion.
Ten-year follow-up data from the US Food and Drug Administration investigational device exemption trial comparing BRYAN® Cervical Disc (Medtronic, Dublin, Ireland) arthroplasty to anterior cervical discectomy and fusion (ACDF) demonstrated that disc arthroplasty maintained range of motion and improvements in overall success and neck disability. ⋯ Compared with ACDF, fewer patients with the BRYAN® disc required surgery for symptomatic adjacent level degeneration, but this did not achieve statistical significance. Analysis of combined study data using Bryan and Prestige discs shows significant differences in SADLRS as early as 7 yr.

Multicenter Study
Stereotactic Radiosurgery for Trigeminal Neuralgia in Patients With Multiple Sclerosis: A Multicenter Study.
Facial pain response (PR) to various surgical interventions in patients with multiple sclerosis (MS)-related trigeminal neuralgia (TN) is much less optimal. No large patient series regarding stereotactic radiosurgery (SRS) has been published. ⋯ In this largest series SRS offers a reasonable benefit to risk profile for patients who have exhausted medical management. More favorable initial response to SRS may predict a long-lasting pain control.

Multicenter Study Clinical Trial
Nonawake vs Awake Placement of Spinal Cord Stimulators: A Prospective, Multicenter Study Comparing Safety and Efficacy.
Spinal cord stimulation (SCS) is a common intervention for managing intractable pain. Generally, leads are implanted in a minimally invasive procedure with verbal feedback regarding the location and nature of generated paresthesias by active stimulation; in this way their optimal location can be confirmed. However, lead placement under general anesthesia can have additional benefits. ⋯ Electrophysiological monitoring during asleep SCS implantation is a robust tool becoming more frequently used. This comparative prospective series demonstrates that asleep placement allows for shorter procedure and operating room times with superior paresthesia coverage profiles, while maintaining lower adverse events and equal clinical outcomes for pain relief.

Multicenter Study
Stereotactic Radiosurgery for Intracranial Ependymomas: An International Multicenter Study.
Stereotactic radiosurgery (SRS) is a potentially important option for intracranial ependymoma patients. ⋯ SRS provides another management option for residual or recurrent progressive intracranial ependymoma patients who have failed initial surgery and RT.
