1/29. Devic's neuromyelitis optica during pregnancy in a patient with systemic lupus erythematosus.Neuropsychiatric forms of systemic lupus erythematosus (SLE) vary, most commonly consisting of seizures, psychiatric disturbances, or focal central nervous deficits. This is a new case of neuromyelitis optica or Devic's syndrome during the course of SLE. Few reports of this association exist in the literature. Our objective is to report this unique case of Devic's neuromyelitis optica during pregnancy in a patient with systemic lupus erythematosus. A 28-year-old woman had been diagnosed as having SLE with cutaneous and articular involvement in 1987 when she was 17 years old. She was treated with a synthetic antimalarial agent associated with corticosteroids. In 1994, during the fourth month of pregnancy, she had signs of transverse myelitis with a sensory level at T6 associated with an optic neuropathy suggesting a Devic's syndrome. The patient was managed by plasmapheresis sessions and intravenous corticosteroids. Transverse myelitis recurred postpartum and three years later at the same thoracic level. Management by bolus administration of a steroid and cyclophosphamide resulted in remission again. There have only been around a dozen reports in the literature of patients who had both Devic's neuromyelitis optica and SLE. magnetic resonance imaging is contributive to diagnosis and therapeutic follow-up, showing spinal cord lesions with increased intensity on T2-weighted sequences. Although the clinical course of the present patient has been favourable so far, the prognosis of this neurologic disease is generally considered to be poor with elevated mortality.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
2/29. Progressive necrotic myelopathy: clinical course in 9 patients.OBJECTIVE: To review the clinical, laboratory, and radiological findings of 9 patients who had progressive idiopathic myelopathy with evidence of spinal cord necrosis. DESIGN AND methods: We reviewed personally examined cases of myelopathy that fulfilled the following criteria: (1) regional loss of reflexes, flaccidity, and muscle atrophy; (2) magnetic resonance imaging showing a shrunken or cavitated cord without evidence of arteriovenous malformation; (3) electromyogram showing denervation over several contiguous spinal cord sgements with preservation of sensory potentials in some cases; and (4) the absence of evidence of systemic disease or neoplasm. RESULTS: The illness began in these patients after the age of 40 years, with prominent burning or tingling limb pain, occasionally with radicular features or with less well-defined back, neck, or abdominal pain. Leg or infrequently arm weakness appeared concurrently or soon after the onset of pain. The most distinctive feature was a saltatory progression of symptoms, punctuated by both acute and subacute worsenings approximately every 3 to 9 months, culminating in paraplegia or tetraplegia. The distinguishing clinical findings, together indicative of destruction of gray matter elements of the cord, were limb atrophy, persistent areflexia, and flaccidity. The concentration of cerebrospinal fluid protein was typically elevated between 500 g/L and 1000 g/L, without oligoclonal bands, accompanied infrequently by pleocytosis. magnetic resonance imaging showed features suggesting cord necrosis, specifically swelling, T2-weighted hyperintensity, and gadolinium enhancement over several spinal cord segments, succeeded months later by atrophy in the same regions. necrosis of the cord was found in biopsy material from one patient and postmortem pathology in another case, but inflammation and blood vessel abnormalities were absent. Only 2 patients had prolonged visual evoked responses. The disease progressed despite immune-modulating treatments although several patients had brief epochs of limited improvement. CONCLUSIONS: The saltatory course, prolonged visual evoked responses in 2 patients, and a cranial abnormality on magnetic resonance imaging in another, raised the possibility of a link to multiple sclerosis. However, the normal cranial magnetic resonance imaging scans in 6 other patients, uniformly absent oligoclonal bands, and poor response to treatment were atypical for multiple sclerosis. On the basis of shared clinical and laboratory features, idiopathic progressive necrotic myelopathy is indistinguishable from a limited form of Devic disease.- - - - - - - - - - ranking = 2804.0118768943keywords = multiple sclerosis, sclerosis, ms (Clic here for more details about this article) |
3/29. A central demyelinating disease with atypical features.There are clinical, laboratory and imaging criteria to distinguish multiple sclerosis (MS) from neuromyelitis optica (NMO) and acute disseminated encephalomyelitis (ADEM). While MS has unknown aetiology, NMO is commonly associated with vasculitis and ADEM is supposed to be parainfectious in origin. In the present study, six patients are described from a group of 67 with a central demyelinating disorder whose clinical presentation did not conform to existing diagnostic criteria for ADEM, NMO or MS. Their clinical, laboratory and imaging characteristics were studied and analysed. Some features suggested a particular diagnosis but some other features favoured another diagnosis. The features included spinal cord involvement in a large vertical segment with cord swelling, optic neuritis, no lesions in the cerebral cortex, paraplegia with urinary retention during the acute phase, no oligoclonal band in cerebrospinal fluid, absence of any evidence of vasculitis, wide time-gap between spinal cord and optic nerve involvement, good recovery from acute phase of disease and a relatively benign course. We conclude that there exists a subpopulation of patients with central demyelinating disease in this region with mixed clinical features. overall features suggested either a widened clinical spectrum of MS, NMO or ADEM or a possible overlap between them.- - - - - - - - - - ranking = 1401.5059384472keywords = multiple sclerosis, sclerosis (Clic here for more details about this article) |
4/29. Recurrent neuromyelitis optica with diffuse central nervous system involvement: case report.Several demyelinating disorders can affect children. The differential diagnosis between these diseases is usually an arduous task. Diagnostic criteria have been proposed for some of these disorders, however most of them have not yet been clinically and prospectively validated. Here we present a case of a ten year-old boy with recurrent bilateral optic neuritis and spinal cord involvement. Clinical and cerebrospinal fluid data have fulfilled diagnostic criteria for Devic's neuromyelitis optica (NMO). The differential diagnosis with multiple sclerosis (MS) has become troublesome since not only optic nerves and spinal cord were involved. In one of the relapses a left hemiparesis with facial involvement was registered. magnetic resonance imaging was also compatible with MS. This case illustrates that CNS demyelinating disorders can fulfill diagnostic criteria for more than one demyelinating disease, making the clinical judgment an important tool in the management of these patients.- - - - - - - - - - ranking = 1401.5059384472keywords = multiple sclerosis, sclerosis (Clic here for more details about this article) |

6/29. Gluten sensitivity and neuromyelitis optica: two case reports.neuromyelitis optica is a clinical syndrome characterised by acute transverse myelitis plus an acute or subacute optic neuritis with or without recovery. Although once believed to be a variant of multiple sclerosis, diagnostic criteria have recently been proposed for neuromyelitis optica, making it a clinically distinct syndrome. The term gluten sensitivity refers to a state of heightened immunological responsiveness to ingested gluten in genetically susceptible individuals, as indicated by circulating antibodies to gliadin. Several neurological complications have been described associated with gluten sensitivity ranging from peripheral neuropathy and cerebellar ataxia to an increased risk of epilepsy. Although myelopathy has been described in some case reports of coeliac disease, neuromyelitis optica has never been described in association with gluten sensitivity. We describe two cases of gluten sensitivity presenting as neuromyelitis optica with no previous history of significant gastrointestinal symptoms. Gluten sensitivity was confirmed by immunological and histological studies.- - - - - - - - - - ranking = 1402.5059384472keywords = multiple sclerosis, sclerosis, ms (Clic here for more details about this article) |
7/29. Successful high dose glucocorticoid treatment for subacute neuromyelitis optica with systemic lupus erythematosus.A 54-year-old Japanese woman with a 6-year history of systemic lupus erythematosus (SLE) was admitted to our hospital suffering from acute blindness in her right eye. Her condition recovered after steroid pulse therapy, however, 18 months later she suffered from nuchal pain for 2 weeks after which right hemiparesis with urinary incontinence developed. A spinal magnetic resonance imaging (MRI) revealed cord swelling from C2 to C7. She was diagnosed with neuromyelitis optica (NMO) and intravenous steroid administrations were immediately commenced. Her condition promptly improved. This case was unique because the steroid treatment was quite effective for this case of myelitis, which had passed the acute phase. We supposed that, because most of the lesion was not necrotic or demyelinated, but rather showed edematous change caused by vasculitis based on autoimmune pathogenesis, the symptoms progressed rather gradually and improved promptly in response to glucocorticoid treatment.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
8/29. neuromyelitis optica (Devic's syndrome) as first manifestation of systemic lupus erythematosus.Neurologic symptoms rarely occur as presenting feature of systemic lupus erythematosus (SLE). We describe a 37-year old woman who presented with several episodes of transverse myelitis and optic neuritis. Clinical, radiologic and laboratory findings were compatible with neuromyelitis optica (NMO). Seven years after disease onset clinical and laboratory findings were diagnostic for SLE. This case illustrates that NMO may represent a first manifestation of SLE for many years.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
9/29. Demyelinating peripheral neuropathy in Devic disease.This is a report of a 20-year-old man with typical features of Devic disease (neuromyelitis optica) associated with demyelinating peripheral neuropathy. A sural nerve biopsy showed markedly decreased myelinated fibers of a large diameter. Teased fiber preparations showed segmental remyelination in 50% of examined fibers, as well as a few demyelination. Demyelination of bilateral optic nerves, spinal cord, and peripheral nerves at the same time suggests a possibility of common pathogenetic mechanisms in both the central and peripheral nervous systems.- - - - - - - - - - ranking = 2keywords = ms (Clic here for more details about this article) |
10/29. Progressive necrotizing myelopathy: part of the spectrum of neuromyelitis optica?This case series reviews the clinical, radiographic and laboratory findings of five patients with progressive idiopathic myelopathy with evidence of cord necrosis who presented in our institution over a 5 year period ending in May 2005. patients fulfilling the following criteria were included: (1) presentation with myelopathy without overt visual involvement at initial presentation; (2) demonstration with magnetic resonance imaging (MRI) of contiguously abnormal signal in the spinal cord spanning at least three vertebral segments without evidence of arteriovenous malformation or significant disk disease; (3) absence of systemic disease or neoplasm. All patients were women, identified themselves as African American and were older than 35 years. Pain was reported at initial presentation in four cases. The distinctive feature was a relapsing course with intervening variable improvement of function and progression to quadriplegia in less than 4 years. An increased IgG index and/or oligoclonal banding was detected in two patients. The leukocyte count in the cerebrospinal fluid (CSF) was elevated in all cases but in only one specimen did the count exceed 50 cells. None of the patients initially had clinical signs of an optic neuropathy but unilaterally prolonged visual evoked potentials were present in one individual who went on to developed optic neuritis 19 months after the first clinical presentation. Another patient developed optic neuritis 45 months after disease onset. Immunomodulatory and plasma exchange therapy were of some benefit at least early in the course but the disease progressed despite these interventions. neuromyelitis optica (NMO)-IgG antibody, a serum or CSF marker described in individuals with classic NMO and optico-spinal multiple sclerosis (MS), was present in all cases. On the basis of shared clinical and imaging features in the cord, progressive necrotizing myelopathy observed in this case series exhibits key features of a limited form of NMO (Devic's disease) and opticospinal MS. The presence of NMO-IgG antibody marker suggests that progressive necrotizing myelopathy is part of a disease spectrum of which traditional NMO is a select presentation.- - - - - - - - - - ranking = 1402.5059384472keywords = multiple sclerosis, sclerosis, ms (Clic here for more details about this article) |
