OBJECTIVE To provide the first insights into the potential role of skull base chordoma, which causes brainstem compression in and around Barrington's nucleus and its effect on the micturition center. Chordoma is a rare malignant bone tumor that originates from the remnants of the embryonic notochord, which normally forms and dissolves during early fetal(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)
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)
AIM To investigate the expression of platelet-derived growth factor (PDGF) receptor-A (PDGFRα), epidermal growth factor receptor (EGFR) and c-Met in spinal chordoma. To the authors' knowledge, little is known regarding the prognostic significance of receptor tyrosine kinase in spinal chordoma. MATERIALS AND METHODS Using immunohistochemical techniques,(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)
To clarify whether vascular endothelial growth factor receptor 2 (VEGFR2) and inducible nitric oxide synthase (iNOS) are involved in the angiogenesis and recurrence of spinal chordoma tissues and influence the overall survival. All patients affected by a spinal chordoma surgically treated between 1986 and 2007 were reviewed. We examined the expression of(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)
