Reiter's syndrome belongs to the family of spondyloarthropathies that usually present with a triad of arthritis, urethritis, and uveitis. The diagnostic criteria include clinical, radiological, and genetic findings, and the response to treatment. Nervous system involvement in Reiter's syndrome is extremely rare. We report here on a 36-year-old man who initially presented with progressive cervic...
BACKGROUND AND PURPOSE MR findings reported in conjunction with spinal dural arteriovenous fistula (SDAVF) include cord swelling, increased T2 signal within the spinal cord, and parenchymal enhancement, each of which is nonspecific. Enlarged vessels on the cord surface, the most specific MR finding, is noted in only half of SDAVF patients. Nevertheless, we have frequently observed MR peripheral...
Background Non-traumatic myelopathy is common in Africa and there are geographic differences in etiology. Clinical management is challenging due to the broad differential diagnosis and the lack of diagnostics. The objective of this systematic review is to determine the most common etiologies of non-traumatic myelopathy in sub-Saharan Africa to inform a regionally appropriate diagnostic algorith...
BACKGROUND The manner of measuring the outcome of cervical myelopathy must be patient-oriented and have sufficient reliability and validity. The current Japanese Orthopaedic Association (JOA) scoring system for cervical myelopathy is widely used but has not met this requirement. The first- and second-round surveys established 24 items for inclusion on a new questionnaire for cervical myelopathy...
SUMMARY Two patients with a chronic progressive myelopathy were successfully surgically treated and idiopathic hypertrophic spinal pachymeningitis (IHSP) was found on histology. In both patients, an extensive extramedullary mass of low T2 signal with peripheral contrast enhancement was compressing the spinal cord on MR imaging. This imaging appearance in patients with chronic progressive myelop...
INTRODUCTION In patients with Tourette's syndrome who have severe motor tics, involuntary neck movements can enhance degenerative changes in the cervical spine, occasionally causing myelopathy. There have been a limited number of reports on surgical treatment for cervical myelopathy caused by Tourette's syndrome, and a consensus for surgical treatment has not been fully established. To the best...
PURPOSE Microvascular permeability changes and loss of blood-brain barrier integrity are important features of central nervous system (CNS) radiation injury. Expression of vascular endothelial growth factor (VEGF), an important determinant of microvascular permeability, was examined to assess its role in CNS radiation damage. Because hypoxia mediates VEGF up-regulation through hypoxia-inducible...
OBJECTIVE It has been suggested that the vascular endothelial growth factor (VEGF) gene expression plays an important role in radiation-induced injury to the spinal cord. This study assesses the radioprotective effects of N-acetyl-5-methoxytryptamine (melatonin) through its modulation of VEGF expression after localized irradiation of the cervical spinal cord. MATERIALS AND METHODS In this exp...
