11/431. Analgesic effect of oral ketamine in chronic neuropathic pain of spinal origin: a case report.ketamine is an injectable anesthetic induction agent that has been reported to have analgesic activity in pain from a variety of mechanisms, but predominantly in neuralgic and dysesthetic neuropathic pain. In this case report we illustrate the effectiveness of ketamine in a patient with neuropathic pain resulting from cauda equina trauma. Among the issues addressed are the role of pretreatment with haloperidol to prevent ketamine-induced psychomimetic effects, the potential for fewer side effects and a need for lower doses when ketamine is administered orally, and the need for further study regarding appropriate monitoring parameters during the titration phase. Oral ketamine can be effective in treatment refractory chronic neuropathic pain of spinal origin.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
12/431. syringomyelia and complex regional pain syndrome as complications of multiple sclerosis.OBJECTIVE: To describe a patient from Southeast asia with the optic-spinal phenotype of multiple sclerosis who developed syringomyelia and resultant complex regional pain syndrome (formerly named reflex sympathetic dystrophy). DESIGN: Case report. SETTING: Department of neurology at a tertiary care hospital in the Republic of singapore. PATIENT: A 53-year-old Chinese woman with a history of optic neuritis developed an episode of left hemiparesis leading to a diagnosis of multiple sclerosis. Serial neuroimaging studies revealed an active demyelinating plaque in the cervical area that later progressed into a syrinx. Over a period of 1 year she also developed signs of sympathetic dysfunction including horner syndrome of the left eye and complex regional pain syndrome in the left hand. CONCLUSIONS: A case of the optic-spinal phenotype of multiple sclerosis that is commonly observed in Southeast asia is described. This characteristically tissue-destructive form of multiple sclerosis resulted in syringomyelia complicated by a complex regional pain syndrome. Possible pathogenic mechanisms for these associations are discussed.- - - - - - - - - - ranking = 36325.883628842keywords = multiple sclerosis, sclerosis, ms (Clic here for more details about this article) |
13/431. Symptomatic sacral extradural arachnoid cyst associated with lumbar intradural arachnoid cyst.A case of sacral extradural arachnoid cyst associated with lumbar intradural arachnoid cyst in a 35-year-old male is reported. The patient presented with a history of severe sacrococcygeal pain, constipation, and dysuria for several months. Computed tomographic (CT) myelograms and magnetic resonance imaging (MRI) scans showed a huge sacral cyst without neural components. A favorable outcome could be achieved by decompression of the cyst, obliteration of the fistulous channel between the cyst and the thecal sac, and fenestration of the arachnoid cyst into the subarachnoid space. The relevant literatures are also reviewed.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
14/431. Delayed focal neurological deficit secondary to a cervico-thoracic spinal cord epidural haematoma.This is a report of an elderly woman who developed focal neurological deficit in association with a cervico-thoracic spinal epidural haematoma. Symptoms developed several days after the initial injury and subsequently resolved without surgical intervention. The unusual features of this presentation are discussed.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
15/431. HTLV-I-associated myelopathy: acute progression and atypical MR findings.We describe serial MR imaging findings in a patient with HTLV-I-associated myelopathy. The patient had acute progression of neurologic symptoms and exhibited swelling of the entire length of the spinal cord with increased T2 signal and contrast enhancement on MR imaging. The spinal cord became atrophic a few years later.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
16/431. endoscopy of the spinal cord: cadaveric study and clinical experience.Recent improvements in instruments permit endoscopic examination of previously inaccessible sites. We report on the clinical use of a small-diameter endoscope to examine the spinal subarachnoid space, cord surface and syrinx cavities. Prior to clinical application, three types of endoscopes with external diameters of 0.5, 1.4 or 2.2 mm were inserted percutaneously in the lumbar region of five cadavers for preclinical evaluation of the procedure and the three endoscopes. The observations permitted us to perform spinal endoscopy preoperatively or intraoperatively using the 0.5-mm instrument in seven patients with spinal cord lesions between 1995 and 1997. The patients included two with spinal cord herniation through a dural defect, two with syringomyelia, one with spinal arachnoid cyst, one with spinal epidural cyst and one undergoing lumboperitoneal shunt for hydrocephalus. In patients in whom an endoscope was used preoperatively, the endoscope provided morphological information useful in preoperative diagnosis and planning surgical strategy. When the endoscope was used intraoperatively, areas outside the field of vision of a microscope could be examined, and physiological evaluation could include visualizing improved cord perfusion from the spinal subarachnoid space after surgery. endoscopes could be safely inserted and approached to the lesions under direct vision while avoiding blood vessels and nerve roots on the spinal cord surface. No changes in symptoms or complications occurred in association with endoscopy. Using a small-diameter endoscope, the contents of the spinal subarachnoid space could be examined. Further improvements to increase possible endoscopic manipulation and enhance safety may extend the possibilities for endoscopic examination and permit endoscopic treatment.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
17/431. Neonatal escherichia coli meningitis: spinal adhesions as a late complication.We describe two boys who had severe spinal complications in adolescence after a favorable initial recovery from neonatal escherichia coli meningitis. Due to spinal granulomatous adhesions, one boy died after an attempted scoliosis operation (high cord lesion). The other showed severe progressive neurological deterioration with spinal and cerebellar symptoms.Conclusion The severe complication of chronic arachnoiditis with spinal adhesion may occur many years after neonatal acute bacterial meningitis.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
18/431. An MR image of spinal cord sarcoidosis.We present a case of spinal cord sarcoidosis with a unique magnetic resonance imaging (MRI) finding. MRI of the cervical spine revealed an unusual lesion of low signal intensity on T2-weighted image at the core of the lesion surrounded by high signal intensity. T1-weighted gadolinium enhanced image showed a high signal at the core lesion. Low signal intensity on T2-weighted image in the case was suggested to be due to hemosiderin deposition. Steroid therapy dramatically improved clinical symptoms with a marked reduction of peripheral T2 high intensity area and the core lesion size detected by gadolinium enhancement.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
19/431. Holocord intramedullary abscess: an unusual case with review of literature.STUDY DESIGN: A rare case of a holocord intramedullary abscess with review of literature. OBJECTIVES: Summary of clinical presentation, radiology, microbiology, etiology and management of intramedullary spinal cord abscess. abscess involving the entire spinal cord is extremely rare and awareness of such an event could avoid delay in evacuation of the absess. methods: The incidence, clinical presentation, radiological investigations, treatment and etiology of intramedullary spinal cord abscess in 100 consecutive cases are discussed. RESULTS: Intramedullary spinal cord abscesses are rare. Presently, only five cases of holocord intramedullary abscess are described. In our analysis of 100 cases of intramedullary abscess, a male preponderance was found. The first and the third decades were the most common age groups. prognosis is poor if treatment is delayed. Contrast-enhanced MRI is the ideal investigation for diagnosis. Prompt surgical drainage of the abscess with appropriate antibiotic therapy is mandatory since the natural course of the disease has a very unfavourable outcome. staphylococcus and streptococcus were the most common causative organisms. CONCLUSION: Intramedullary spinal cord abscess along the entire length of spinal cord is rare. A thorough history with precise clinical localisation, a high index of suspicion, contrast-enhanced MRI at appropriate level and prompt surgical drainage with appropriate antibiotic therapy are key to the eventual outcome and prognosis.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
20/431. Atopic dermatitis and HTLV-1-associated myelopathy: associated or coincidental disorders?Reports from jamaica have indicated that some patients with infective dermatitis or atopic dermatitis (AD) are seropositive for antibodies to human T-lymphotropic virus type 1 (HTLV-1). We describe a 32-year-old Israeli woman with long-term AD and paresthesia in the distal parts of the extremities. Neurological examination revealed a positive Babinski's sign. HLA typing demonstrated that this patient has the common HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and infective dermatitis haplotype for DRB1* DQB1*. The presence of HTLV-1 was demonstrated with polymerase chain reaction; HTLV-1-antibodies were detected by the Western blot method and by inoculation of the patient's peripheral blood mononuclear cells into F344 rats. This study confirms the presence of HTLV-1 antibodies and proviral genome in a patient with AD which later evolved into HAM/TSP. We cannot yet conclude whether these two diseases are associated or coincidental disorders. copyright (R) 2000 S.Karger AG, Basel- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
