Nuclear parameters as prognostic indicators in glioblastoma patients.

The objective of this study was to determine whether nuclear parameters were associated with prognosis in glioblastoma multiforme. DNA indices, cell cycle parameters, and nuclear population densities were compared with patient survival. Selection criteria included the pathologic diagnosis of a cerebral glioblastoma multiforme, absence of therapy before surgery, and adequate tissue to measure each nuclear parameter studied.

Sacral and presacral tumors: problems in diagnosis and management.

These included 2 chordomas, 1 metastatic renal cell carcinoma, 2 schwannomas (1 malignant, 1 benign), 1 neurofibroma, 1 neurofibrosarcoma, 1 aneurysmal bone cyst, and an exceedingly rare meningioma. The sex of the patients was not significant.

Atlanto-axial rotational limitation secondary to osteoid osteoma of the axis. Case report.

An unusual case of atlanto-axial rotational limitation secondary to an osteoid osteoma of the axis is presented. Transoral microsurgical resection followed by physical therapy improved the clinical symptoms. This case illustrates several unique problems within the cervical spine as well as the efficacy of the transoral approach to the axis.
