Rapid onset transverse myelitis in adolescence: implications for pathogenesis and prognosis.
(1/114)
Five adolescents with transverse myelitis were reviewed. All presented with a rapid onset paralysis of the lower limbs and impairment of bladder control. The maximum disability developed between 10 minutes and six hours. There was no history of trauma, asthma, or prodromal illness. Investigations failed to demonstrate a vascular cause. Extensive spinal cord abnormalities were observed on magnetic resonance imaging. Electrophysiological investigations, performed in four cases, were all consistent with anterior horn cell damage. In all five adolescents there was poor recovery. The underlying pathogenesis of this rapid onset condition remains a subject of debate. Similarities with both transverse myelitis and fibrocartilaginous emboli are evident, widening the spectrum of conditions within the transverse myelitis umbrella. These observations suggest that in rapid onset "transverse myelitis" the combination of extensive hyperintensity on spinal cord neuroimaging with electrophysiological evidence of anterior horn cell involvement might have adverse prognostic significance.

Somatosensory evoked potentials by paraspinal stimulation in acute transverse myelitis.
(2/114)
Somatosensory evoked potentials by paraspinal stimulation were studied in 6 patients with acute transverse myelitis. In one patient in whom posterior tibial somatosensory evoked potentials were not recordable, a poorly formed response was seen with paraspinal stimulation. Slowing of conduction across the involved segment was seen in the remaining 5 patients and fairly correlated with the clinical localization. (+info)
Decrease in multiple sclerosis with acute transverse myelitis in Japan.
(3/114)
Acute transverse myelitis (ATM) may be a manifestation of multiple sclerosis (MS) and was reported to be more common among Japanese MS patients than in Caucasian MS patients. Recently there are arguments whether clinical manifestations of MS may have changed. Therefore, we studied the frequency of ATM in MS and the clinical subtypes of MS in 86 clinically definite MS patients whose onsets were in 1970-1979, 1980-1989, and 1990-1998 in Sendai City, Japan. Fifty-six of the patients were women and 30 were men. Forty-four patients had the conventional form of MS (C-MS) commonly seen in Western countries, and 42 had optic-spinal or spinal forms of MS (OSS-MS). Twenty MS patients had ATM, and all of them were belong to optic-spinal form of MS. ATM was not seen in any cases of C-MS. The mean onset age (years) of the clinical subtypes was 25.5 in C-MS, 34.1 in OSS-MS without ATM, and 30.9 in OSS-MS with ATM. Among the patients whose onset of the disease was in 1970-1979, 60.0% of them were cases of OSS-MS with ATM, but such cases were markedly decreased to 5.3% in 1990-1998. In contrast, the frequency of C-MS increased to 63.2% in 1990-1998 compared with 20.0% in 1970-1979. Analysis of the data by the year of birth of the patients showed similar results. Our data suggest that the frequency of ATM in MS markedly decreased, and that of C-MS increased during the last 30 years in Sendai, Japan. Since the genetic background of Japanese has not changed, some exogenous factors, such as food, infectious microorganisms, and chemicals in our environment, may be responsible for the change. (+info)
Magnetic resonance imaging findings in 13 patients with acute transverse myelitis are reviewed. In 12 cases centrally located high intensity signal extending over few spinal segments was noted. The lesion occupied more than two thirds of the cord's cross-sectional area in 8 patients. Central dot sign was noted in 7 patients. Variable cord enlargement was seen in 5 patients. Contrast study in one patient showed peripheral enhancement. The MR characteristics that help in differentiating transverse myelitis from spinal form of multiple sclerosis are discussed. (+info)
Non-compressive myelopathy: clinical and radiological study.
(5/114)
Fifty seven patients (42 males and 15 females) with non-compressive myelopathy were studied from 1997 to 1999. Acute transverse myelitis (ATM) was the commonest (31) followed by Vit B12 deficiency myelopathy (8), primary progressive multiple sclerosis (5), hereditary spastic paraplegia (3), tropical spastic paraplegia (2), subacute necrotising myelitis (1), radiation myelitis (1), syphilitic myelitis (1) and herpes zoster myelitis (1). 4 cases remained unclassified. In the ATM group, mean age was 30.35 years, antecedent event was observed in 41.9% case, 25 cases had symmetrical involvement and most of the cases had severe deficit at onset. CSF study carried out in 23 patients of ATM revealed rise in proteins (mean 147.95mg%, range 20-1200 mg/dL) and pleocytosis (mean 20.78/cumm, range 0-200 mm3). Oligoclonal band (OCB) was present in 28% of cases of ATM. The most common abnormality detected was a multisegment hyperintense lesion on T2W images, that occupied the central area on cross section. In 6 patients hyperintense signal was eccentric in location. MRI was normal in 4 cases of ATM. Thus ATM is the leading cause of non-compressive myelopathy. Clinical features combined with MRI findings are helpful in defining the cause of ATM. (+info)
Successful treatment of Epstein-Barr virus-induced transverse myelitis with ganciclovir and cytomegalovirus hyperimmune globulin following unrelated bone marrow transplantation.
(6/114)
We report a patient who developed Epstein-Barr virus (EBV)-induced transverse myelitis 19 months after unrelated bone marrow transplantation (BMT). The disease was diagnosed by physical examination, serologic determinations, EBV-specific polymerase chain reaction in peripheral blood lymphocytes and cerebrospinal fluid, and characteristic magnetic resonance imaging scan of the spine. The patient was treated with ganciclovir and cytomegalovirus (CMV) hyperimmune globulin. He gradually improved and recovered completely within 4 weeks. This case suggests that ganciclovir and CMV hyperimmune globulin appear to be effective for the treatment of EBV-induced transverse myelitis in immunocompromised patients following BMT. (+info)
Transverse myelopathy in systemic lupus erythematosus: an analysis of 14 cases and review of the literature.
(7/114)
OBJECTIVE: To give a comprehensive review of transverse myelopathy (TM), a rare but serious condition reported in 1-2% of patients with systemic lupus erythematosus (SLE). METHODS: 14 patients with SLE and TM were evaluated and 91 additional cases published in the English and German literature reviewed. RESULTS: TM presented either as the initial manifestation or within five years of the diagnosis of SLE. Most patients presented with a detectable sensory deficit at the thoracic level. In our 14 patients, 22% of the patients showed complete neurological recovery, whereas in the total patient population of 105 (our cases plus those reviewed in the literature), complete recovery was observed in 50%, partial recovery in 29% and no improvement or deterioration in 21%. Treatment with intravenous methylprednisolone followed by cyclophosphamide seemed to be most effective. Seventy per cent of the total patient population had abnormal magnetic resonance imaging findings. In our group of 14 patients, those with higher disease activity (measured by the SLAM) at onset of TM were treated more aggressively (for example, with plasmapheresis and intravenous pulse cyclophosphamide). TM in our patients was associated with antiphospholipid antibodies in 43% of the cases as compared with 64% of the total patient population. Optic neuritis occurred in 48% of the total patient population with SLE and TM, suggesting an association. CONCLUSIONS: TM in SLE is a poorly understood entity. Outcome might be more favourable than previously suggested. There is an association of TM with antiphospholipid antibodies in SLE patients. Treatment including intravenous cyclophosphamide may improve the final outcome. This report emphasises the need for multicentre trials to establish guidelines for optimal treatment. (+info)
Sjogren's syndrome with primary biliary cirrhosis, complicated by transverse myelitis and malignant lymphoma.
(8/114)
A 53-year-old woman with Sjogren's syndrome (SS) and primary biliary cirrhosis (PBC) complicated by transverse myelitis (TM) and malignant lymphoma (ML) is reported. TM has been described only in seven cases of primary SS, including three with PBC and four without PBC. The features of SS associated with PBC and complicated by TM were less typical compared with those seen in SS without PBC complicated by TM. This case is the first report of a case with SS, PBC, TM and ML. SS in association with PBC is, in general, overlooked, but such cases must be investigated with great caution for extraglandular complications. (+info)
