Chordomas are locally invasive tumors that have a tendency to relapse despite optimal treatment. Specific biological markers might be used to describe their behavior. There is currently no agreement regarding the best way to manage intracranial chordomas. We studied the expression of vascular endothelial growth factor receptor 2 (VEGFR-2), inducible nitric(More)
BACKGROUND Patients undergoing spinal surgery while under anticoagulation therapy are at risk of developing bleeding complications, even though lower incidences have been reported for joint arthroplasty surgery. There is a gap in the medical literature examining the incidence of postoperative spinal bleeding in patients who were under anticoagulation(More)
Background: Endoscopic discectomy method is a novel technique that is increasingly used in spine surgery. Previous studies have reported that some common complications like dural adhesions are lower in this technique compared with the other techniques. Furthermore, treatment outcomes are reportedly higher because of minimal invasion. Thepresent study aims(More)
Chordomas are rare, locally aggressive malignancies that often exhibit an insidious natural history and are difficult to eradicate. Surgery and radiotherapy are the treatment mainstays of chordoma, but the chance of local recurrence remains high. Reports of receptor tyrosine kinase (RTK) expression in chordoma suggest that these tumors may respond to kinase(More)
INTRODUCTION Although perforation of the esophagus, in the anterior cervical spine fixation, is well established, cases with delayed onset, especially cases that present pseudodiverticulum, are not common. In addition, management of the perforation in this situation is debated. CASE REPORT Delayed esophageal pseudodiverticulum was managed in two patients(More)
BACKGROUND Toxic epidermal necrolysis (TEN) is a rare, severe adverse drug reaction. Stevens-Johnson syndrome (SJS) represents the milder end of the spectrum. The exact pathogenesis of TEN and SJS is still unknown. Many drugs, including prednisolone, cyclosporin, and intravenous immunoglobulin (IVIG), have been used in an attempt to halt the disease(More)
