Review Meta Analysis Comparative Study
Percutaneous endoscopic lumbar discectomy versus posterior open lumbar microdiscectomy for the treatment of symptomatic lumbar disc herniation: a systemic review and meta-analysis.
The purpose of this systematic review and meta-analysis was to compare the clinical efficacy between percutaneous endoscopic lumbar discectomy (PELD) versus posterior open lumbar microdiscectomy (OLMD) for the treatment of symptomatic lumbar disc herniation. ⋯ Based on the present meta-analysis, no significant difference existed in VAS and ODI scores between the 2 surgical procedures, and they were also similar in terms of operation time, complication rate, and incidence of recurrence and reoperation, but PELD showed shorter hospital stay and time of return to work. Thus, under the premise of careful manipulation and complete decompression, we consider that PELD is a relatively more minimally invasive technique, which could be an alternative to OLMD.

This study provides a systematic review and meta-analysis of psychiatric disorders caused by craniopharyngiomas and the hypothalamic alterations underlying these symptoms. ⋯ Craniopharyngiomas primarily involving the hypothalamus represent a neurobiological model of psychiatric and behavioral disorders.

Review Case Reports
Intracranial non-skull-based chondrosarcoma arising from the sagittal sinus: a case report and review of literature.
Intracranial nonskull-based chondrosarcoma is a very rare malignant tumor. In fact, it is difficult to diagnose because of its atypical radiologic and morphologic features. We report a case of an intracranial parasagittal chondrosarcoma in the left parietal lobe accompanied with significant peritumoral edema (an extremely rare phenomenon for this tumor), with a review of the literature, to clarify aspects in the diagnosis of this rare tumor. ⋯ Although magnetic resonance imaging was performed, it is sometimes difficult to distinguish intracranial chondrosarcoma from meningioma and glioma, especially when the tumor arises from a nonskull base such as the meninges. Some cases could have significant peritumoral edema, although it is extremely rare. Histologic examination may aid in the diagnosis of this tumor. Neurosurgery is the most effective therapy for these tumors. Postoperative radiotherapy needs to be considered when the tumor is incompletely resected, has atypical histology, or is associated with significant peritumoral edema.

Randomized Controlled Trial
Wallis Interspinous Spacer for treatment of primary lumbar disc herniation: three-year results of a randomized controlled trial.
Limited data have been reported showing whether the second-generation Wallis interspinous spacer improves function after lumbar spine decompression or discectomy. ⋯ We found that discectomy combined with Wallis implantation was not beneficial for pain relief or lumbar function improvement compared with lumbar discectomy alone. Although the Wallis implant was associated with maintenance of the intervertebral disc height and limited range of motion of the spine, it is probably incapable of preventing recurrent herniation or adjacent segment degeneration.
