Radiofrequency ablation of spinal osteoid osteoma: a prospective study.

OBJECTIVE Surgery has been considered the standard treatment for spinal osteoid osteomas that are refractory to analgesic agents. Radiofrequency ablation (RFA) is a less invasive technique with established efficiency for the treatment of peripheral osteoid osteomas. The main objectives of this study are to evaluate the safety of RFA based on the results of a previous experimental study in rats conducted in the authors' laboratory and to identify its short- and long-term efficiency in the treatment of spinal osteoid osteomas.

Antithrombotic Medication Use and Misuse Among Patients with Intracranial Hemorrhage: A 16-Year, Lebanese, Single-Center Experience.

Objective/background: The use of antithrombotic medication (ATM) frequently is reported in patients with intracranial hemorrhage (ICH) and is associated with increased mortality. Unfortunately, ATMs sometimes are prescribed and/or used inappropriately. We sought to determine the rate of ATM misprescription/misuse among patients with ICH in a single-center retrospective study.

Spontaneous epidural hematoma of the spine associated with oral anticoagulants: 3 Case Studies.

It is generally caused by a rupture of the postero-internal vertebral venous plexus secondary to minor barotrauma such as cough, peridural catheter insertion.
