Temozolomide for recurrent or progressive high-grade malignant glioma: results of an Austrian multicenter observational study.

Background: The use of chemotherapy in patients with malignant gliomas has remained a controversial issue even after the publication of favorable study data and a meta-analysis. The present study was initiated to support the use of chemotherapy in patients with relapsed high-grade gliomas (HGG).

Patients And Methods: Six Austrian centers recruited 43 patients with histologically confirmed HGG at first recurrence.

Microsurgical treatment of juxta facet cysts of the lumbar spine.

Objectives: Juxta facet cysts are a common cause of low back and radicular pain. They are mostly associated with degenerative facet joints and spondylolisthesis. The study focuses on long-term outcomes after microsurgical treatment without fusion.

Intraoperative evaluation of implants in anterior cervical spine surgery by three-dimensional fluoroscopy.

Objective: Accurate radiographic documentation of the proper placement of cages, plates, and screws following cervical spine surgery significantly impacts clinical outcome. Postoperative computed tomography scans clearly show that the position of implants is sometimes far from ideal. The morbidity of anterior cervical disc surgery is well documented, but the incidence and influence of the misplacement of interbody spacers, plates, and screws are underestimated.
