Abstract
OBJECTIVE To study immunologic alterations in patients with neuromyelitis optica (NMO). METHODS The authors studied 8 patients with NMO together with 16 healthy subjects, 16 patients with relapsing remitting multiple sclerosis (RRMS), and 16 patients with secondary progressive MS (SPMS), matched for age and sex, as controls. Because recent histopathologic studies have demonstrated that active NMO lesions consist of perivascular immunoglobulin (Ig) deposition and eosinophil infiltration, IL-5, IL-6, IL-12, IgG, and IgM production by anti-myelin oligodendrocyte glycoprotein (MOG) mononuclear cells in peripheral blood and CSF were selected for study using ELISPOT. Eotaxin-2 (Eo-2) and eotaxin-3 (Eo-3) levels were also assessed using ELISA and eosinophil cationic protein (ECP) levels by radioimmunoassay. RESULTS MOG-specific responses in CSF showed significant increase in IL-5, IL-6, IgG, and IgM secreting cells in NMO patients compared with patients with RRMS, SPMS and healthy subjects. Interestingly, numbers of IgM secreting cells were significantly higher than identical specificity IgG secreting ones. Moreover, CSF Eo-2, Eo-3, and ECP levels were also significantly higher in NMO patients compared to all three control populations. Anti-MOG IL-12 secreting cells were increased in CSF and peripheral blood from NMO, RRMS, and SPMS patients when compared to healthy subjects. CONCLUSIONS These observations suggest that neuromyelitis optica is associated with a major humoral immune response (particularly anti-MOG IgM production) and eosinophil activation present exclusively in CSF.

Abstract
Neuromyelitis optica (NMO) is an inflammatory demyelinating disease that selectively affects optic nerves and spinal cord. It is considered a severe variant of multiple sclerosis (MS), and frequently is misdiagnosed as MS, but prognosis and optimal treatments differ. A serum immunoglobulin G autoantibody (NMO-IgG) serves as a specific marker for NMO. Here we show that NMO-IgG binds selectively to the aquaporin-4 water channel, a component of the dystroglycan protein complex located in astrocytic foot processes at the blood-brain barrier. NMO may represent the first example of a novel class of autoimmune channelopathy.

Abstract
The rapid development of paraparesis or tetraparesis combined with a bilateral sensory deficit that has a clearly defined rostral border and bladder dysfunction are the principal features of acute transverse myelopathy. Acute partial transverse myelopathy is far much more frequent: its symptoms are asymmetric, sometimes unilateral, and sensory deficit may predominate. An urgent MRI is required to exclude acute spinal cord compression. Diagnosis of ischemic acute transverse myelopathy includes the following elements: sudden onset, neurologic symptoms compatible with infarction in the anterior spinal artery area (by far the most frequent location for spinal cord infarction), and presence of a specific cause of spinal cord ischemia. In all other cases where it is difficult to distinguish spinal cord infarction from myelitis, analysis of the cerebrospinal fluid is essential. Most cases of inflammatory acute transverse myelopathy can be linked to a defined cause. Multiple sclerosis is a major cause of partial acute transverse myelopathy. MRI lesions are usually small, located in the lateral or posterior part of the spinal cord. Diagnostic elements include multiple lesions of multifocal demyelination on the cerebral MRI, oligoclonal bands in the cerebrospinal fluid, and the absence of clinical or laboratory abnormalities that suggest systemic disease. Neuromyelitis optica, also known as Devic's disease, has often been considered a variant form of multiple sclerosis. Recent immunologic studies confirm the hypothesis that it is a distinct entity. Infectious transverse acute myelitis is often of viral origin. It may result from direct viral stress but more frequently follows immunologically-mediated indirect stress. This acute parainfectious myelitis, like postvaccinal myelitis, may be considered as a spinal single-focus form of acute disseminated encephalomyelitis (ADEM). It is important to distinguish the latter from an initial episode of multiple sclerosis, because their prognosis and treatment differ.

Abstract
The combination of optic neuritis and myelitis, the so-called Neuromyelitis optica is an uncommon pattern of demyelinating disorder. In 1870, Sir Thomas Clifford Allbutt first reported the association and Erb published a comparable report. Gowers and Dreschfeld described other instances in the 19th century. This paper attempts to review the syndrome to consider whether it merits recognition as a disease, sui generis, or rather as a syndrome symptomatic of multiple sclerosis, acute disseminated encephalomyelitis, and other immunological disorders. Two forms are distinguished: a monophasic illness, and a relapsing form. The claimed differential features separating it from classical multiple sclerosis are appraised. Modern immunology suggests an antibody-dependent, complement-mediated pathogenesis.

Abstract
Neuromyelitis optica (Devic's syndrome) is an uncommon, idiopathic, demyelinating syndrome of the central nervous system that preferentially affects the optic nerves and spinal cord. It frequently is misdiagnosed as severe multiple sclerosis, but usually is readily distinguished from multiple sclerosis in fully developed cases because of its severity, typical magnetic resonance imaging (MRI) findings (normal brain MRI; longitudinally extensive lesions on spinal cord MRI), and cerebrospinal fluid analysis (polymorphonuclear pleocytosis and absence of oligoclonal banding). A serum autoantibody marker, NMO-IgG, is highly specific for the disorder. Most patients have relapsing disease, and natural history studies confirm early and severe disability. We treat acute myelitis and optic neuritis exacerbations with parenteral corticosteroids and use rescue plasmapheresis for severe, refractory attacks. Immunomodulatory drugs used for typical multiple sclerosis seem ineffective for relapse prevention. We recommend systemic immunosuppression, usually with azathioprine and oral corticosteroids, for most patients. Fulminant disease and breakthrough disease may respond to other forms of humoral immunotherapy such as rituximab.

Abstract
INTRODUCTION Optic neuromyelitis or Devic's syndrome is a very rare disease affecting the optic tracts and the spinal cord. Its association with evolving pulmonary tuberculosis has been noted in a handful of case reports. CASE REPORT The authors reportthe case of a 40 year old patient with evolving pulmonary tuberculosis who experienced bilateral blindness followed by paraplegia and sphincter disturbance. Clinical examination and investigations excluded direct tuberculous involvement of the nervous system or a reaction to antituberculous therapy and Devic's syndrome was diagnosed, based on Wingerchurk's criteria. Following treatment with corticosteroids and antituberculous chemotherapy, the patient recovered normal mobility and sphincter control but remained completely blind. CONCLUSIONS Throughout this case report, the authors emphasise the rarity of this association and discuss the pathophysiological mechanism, which appears to be an immune dysfunction triggered by mycobacterial infection.

Abstract
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.

Abstract
BACKGROUND Neuromyelitis optica is an inflammatory demyelinating disease with generally poor prognosis that selectively targets optic nerves and spinal cord. It is commonly misdiagnosed as multiple sclerosis. Neither disease has a distinguishing biomarker, but optimum treatments differ. The relation of neuromyelitis optica to optic-spinal multiple sclerosis in Asia is uncertain. We assessed the capacity of a putative marker for neuromyelitis optica (NMO-IgG) to distinguish neuromyelitis optica and related disorders from multiple sclerosis. METHODS Indirect immunofluorescence with a composite substrate of mouse tissues identified a distinctive NMO-IgG staining pattern, which we characterised further by dual immunostaining. We tested masked serum samples from 102 North American patients with neuromyelitis optica or with syndromes that suggest high risk of the disorder, and 12 Japanese patients with optic-spinal multiple sclerosis. Control patients had multiple sclerosis, other myelopathies, optic neuropathies, and miscellaneous disorders. We also established clinical diagnoses for 14 patients incidentally shown to have NMO-IgG among 85000 tested for suspected paraneoplastic autoimmunity. FINDINGS NMO-IgG outlines CNS microvessels, pia, subpia, and Virchow-Robin space. It partly colocalises with laminin. Sensitivity and specificity were 73% (95% CI 60-86) and 91% (79-100) for neuromyelitis optica and 58% (30-86) and 100% (66-100) for optic-spinal multiple sclerosis. NMO-IgG was detected in half of patients with high-risk syndromes. Of 14 seropositive cases identified incidentally, 12 had neuromyelitis optica or a high-risk syndrome for the disease. INTERPRETATION NMO-IgG is a specific marker autoantibody of neuromyelitis optica and binds at or near the blood-brain barrier. It distinguishes neuromyelitis optica from multiple sclerosis. Asian optic-spinal multiple sclerosis seems to be the same as neuromyelitis optica.

Abstract
OBJECTIVE Multiple sclerosis (MS) is by far the most popular diagnosis for patients with multifocal neurological disease. Owing to demyelinating inflammatory non-necrotic plaques of the white matter, MS can give remitting symptoms of virtually every part of the central nervous system. Corticosteroids are usually helpful. Devic's neuromyelitis optica (DNMO) is a neurological disease involving only the optic nerves and the spinal cord, where demyelination evolves towards necrosis and atrophy; the prognosis is poor and no satisfactory treatment is known. The objectives of this study are to describe clinical, biological, pathological and radiological data of patients with DNMO and to differentiate DNMO from MS. MATERIAL AND METHODS We studied the files of 14 patients diagnosed with possible DNMO in three French hospitals between 1980 and 1999 and reviewed the literature. RESULTS Nine patients were included as definite DNMO. Five were excluded because they did not fulfil the diagnostic criteria. For the nine patients with definite DNMO, DNMO was either monophasic or multiphasic. The prognosis was generally poor: two patients died and five others developed severe disability such as blindness, para or quadriplegia or both. Cerebrospinal fluid study and neuroimaging were essential to confirm the diagnosis of DNMO. Various immunosuppressive treatments generally failed to benefit the patients. CONCLUSION In the literature (as well as our 14 initial patients) only a few cases of patients described as suffering from DNMO fulfilled the diagnostic criteria. The others showed evidence that another disease like MS was involved. We stress that inclusion and exclusion criteria have to be kept in mind to differentiate clearly DNMO from MS and other central nervous system white matter diseases.

Abstract
OBJECTIVE Although epidemiology indicates that multiple sclerosis is more common among whites than African Americans, the course of disease may be more aggressive among African Americans. This study examines disease course in a large multiple sclerosis clinic population. DESIGN A case-controlled, retrospective record review compared the severity of multiple sclerosis for African Americans and for whites. Because the baseline demographics of the two groups differed, we performed analyses of multiple subgroups in an attempt to control for various characteristics. RESULTS Consistent evidence of more disability in African Americans compared with whites was found, although subgroups were often too small to establish statistical significance. African Americans had a higher mean Expanded Disability Status Scale score than whites in a subgroup selected to minimize differences in access to care and disease perceptions. African Americans reported limb weakness as a presenting symptom of multiple sclerosis more frequently than did whites. When patients were followed at our multiple sclerosis center, rates of disease progression were nearly identical. CONCLUSIONS More African Americans than whites experience pyramidal system involvement early in multiple sclerosis, leading to greater disability as measured by the ambulation-sensitive Expanded Disability Status Scale. Once patients have moderate difficulty walking, the rate of progression is the same for both groups, albeit occurring at a later age for whites than for African Americans.

Abstract
Postinfectious forms of encephalomyelitis, also termed acute disseminated encephalomyelitis (ADEM), form one of several categories of inflammatory demyelinating disorders of the central nervous system (CNS). Recent large, retrospective case series have refined our understanding of the clinical, laboratory, and neuroimaging characteristics of ADEM. The differences between childhood and adult ADEM, risks of development of multiple sclerosis, and the contributions of recent studies to refining the nosology of CNS demyelinating syndromes are discussed.

Abstract
Multiple sclerosis (MS) in Asian populations is characterised by the selective and severe involvement of the optic nerve and spinal cord as well as low prevalence rates. 15-40% of cases of MS in Japan are of this "opticospinal" type. This form of MS generally has a higher age at onset and a higher female to male ratio than conventional MS. Opticospinal MS is also characterised by frequent relapses, severe disability, few brain lesions visible on MRI, long lesions extending over many vertebral segments visible on spinal-cord MRI, pleocytosis and an absence of oligoclonal bands in the CSF, and a pronounced shift in the responses of T-helper-1 and T-cytotoxic-1 cells throughout relapse and remission phases. Conventional MS in Japanese people is, like MS in white people, associated with HLA-DRB1*1501, whereas opticospinal MS is associated with HLA-DPB1*0501. In Japanese people born after modernisation in the 1960s, the ratio of conventional to opticospinal MS has increased rapidly. Opticospinal MS is likely to have a distinct immune-mediated mechanism, which is not operative in conventional MS.

Abstract
OBJECTIVES To report the clinical features and outcome of 24 Brazilian patients with optic neuromyelitis syndrome (ONM); discuss the underlying pathological events associated with the ONM syndrome; review the nosological situation of ONM in the group of inflammatory and demyelinating diseases of the central nervous system. PATIENTS AND METHODS Patients with ONM treated at the Hospital da Lagoa, Rio de Janeiro were studied. Demographic, clinical, magnetic resonance imaging, cerebrospinal fluid, and pathological data were analysed. RESULTS The study consisted of 20 women, four men of whom 10 were white and 14 Afro-Brazilians. Clinical course was recurrent in 22 cases and monophasic in two. Neurological manifestations at inclusion were: sensory impairment (66%), bilateral (41.6%) or unilateral blindness (20.8%), paraplegia or quadriplegia (37.5%). The EDSS was moderate/severe in 70.8%. The underlying pathological events were respectively pulmonary tuberculosis and upper respiratory infection in the two monophasic cases; in the 22 recurrent ONM patients: pulmonary tuberculosis (3), neurocysticercosis (1), polyarteritis nodosa (1), antinuclear antibody and rheumatoid factor (1), antiphospholipid antibody primary syndrome (1), diabetes mellitus (1), hypothyroidism (1), and amenorrhea-galactorrhea (4). Normal cerebrospinal fluid was found in 52% and an inflammatory profile in 48%. Only four recurrent ONM white patients had brain and spinal cord magnetic resonance imaging and cerebrospinal fluid findings compatible with the diagnosis of multiple sclerosis. Large lesions were seen in 62% of spinal magnetic resonance images. Six of 12 recurrent ONM Afro-Brazilian died. There were no statistical differences in the demographic data of the two ethnic groups. Afro-Brazilians were significantly more severely impaired and had a higher mortality rate than the white patients. CONCLUSION These cases were classified as follows: two monophasic acute disseminated encephalomyelitis; one recurrent disseminated encephalomyelitis; three recurrent ONM associated with Hughes syndrome, autoantibodies and polyarteritis nodosa; six recurrent ONM with endocrinopathies; and finally, four multiple sclerosis cases. The remaining cases were not associated with any other condition. It would seem clear that ONM is a syndrome rather than a single disease.

Abstract
Devic disease is characterized by an attack or attacks of optic neuritis and necrotizing myelitis without clinical or magnetic resonance imaging (MRI) evidence of brain involvement or presence of oligoclonal bands in the cerebrospinal fluid (CSF). More than a century after its first systematic study by the French physician, Eugene Devic, its cause as well as its pathogenesis, remains unknown. Devic disease is both a diagnostic and therapeutic challenge to clinicians. The authors present the latest review on the nature, course, possible mechanisms, and therapeutic options of Devic disease.

Abstract
Devic's disease [neuromyelitis optica (NMO)] is an idiopathic inflammatory demyelinating disease of the CNS, characterized by attacks of optic neuritis and myelitis. The mechanisms that result in selective localization of inflammatory demyelinating lesions to the optic nerves and spinal cord are unknown. Serological and clinical evidence of B cell autoimmunity has been observed in a high proportion of patients with NMO. The purpose of this study was to investigate the importance of humoral mechanisms, including complement activation, in producing the necrotizing demyelination seen in the spinal cord and optic nerves. Eighty-two lesions were examined from nine autopsy cases of clinically confirmed Devic's disease. Demyelinating activity in the lesions was immunocytochemically classified as early active (21 lesions), late active (18 lesions), inactive (35 lesions) or remyelinating (eight lesions) by examining the antigenic profile of myelin degradation products within macrophages. The pathology of the lesions was analysed using a broad spectrum of immunological and neurobiological markers, and lesions were defined on the basis of myelin protein loss, the geography and extension of plaques, the patterns of oligodendrocyte destruction and the immunopathological evidence of complement activation. The pathology was identical in all nine patients. Extensive demyelination was present across multiple spinal cord levels, associated with cavitation, necrosis and acute axonal pathology (spheroids), in both grey and white matter. There was a pronounced loss of oligodendrocytes within the lesions. The inflammatory infiltrates in active lesions were characterized by extensive macrophage infiltration associated with large numbers of perivascular granulocytes and eosinophils and rare CD3(+) and CD8(+) T cells. There was a pronounced perivascular deposition of immunoglobulins (mainly IgM) and complement C9neo antigen in active lesions associated with prominent vascular fibrosis and hyalinization in both active and inactive lesions. The extent of complement activation, eosinophilic infiltration and vascular fibrosis observed in the Devic NMO cases is more prominent compared with that in prototypic multiple sclerosis, and supports a role for humoral immunity in the pathogenesis of NMO. Based on this study, future therapeutic strategies designed to limit the deleterious effects of complement activation, eosinophil degranulation and neutrophil/macrophage/microglial activation are worthy of further investigation.

Abstract
Devic's neuromyelitis optica (NMO) associates optic neuritis and myelitis without any other neurological signs. Many patients with NMO may be diagnosed as having multiple sclerosis (MS), optic neuritis and myelitis being the inaugural symptom in 20% and 5% of MS cases, respectively. The aim of our study was to compare a new NMO cohort with recent studies and to try to determine the place of NMO in the spectrum of MS. We retrospectively studied 13 patients with a complete diagnostic workup for NMO. We compared our data with the most recent studies on NMO and with the criteria proposed by Wingerchuck et al. [Neurology 53 (1999) 1107]. We also determined whether these patients fulfilled the diagnostic criteria for MS. Thirteen patients (10 women and three men, with a mean age of 37.4 years) were included in the study. We found similar results to previously published data, except for an association with vasculitis in 38% of our cases. All but three of the patients fulfilled the clinical criteria for MS and two patients fulfilled both clinical and MRI criteria for MS. However, if we applied more restrictive criteria concerning spinal cord and brain MRI and CSF, none of our NMO patients fulfilled the MS diagnostic criteria. NMO might therefore be differentiated from MS by the application of more stringent criteria. Furthermore, all NMO patients should be investigated for vasculitis, even those with no history of systemic disease.

Abstract
Neuromyelitis optica (NMO) is a rare syndrome characterized by the combination of acute optic neuritis and transverse myelitis, usually not seen in Multiple Sclerosis (MS) and other demyelinating syndromes of the central nervous system (CNS). A high prevalence of various autoantibodies has been described in patients with NMO suggesting a polyclonal activation of the humoral immune system. We examined autoantibody responses to myelin (MBP, MOG with isotypes and epitopes) and astroglial (S100beta) antigens in four patients with NMO by ELISA and Immunoblot. All patients showed a positive anti-MOG response, with one showing reaction to the MOG epitope corresponding to amino acid sequence 63-87. MBP-autoantibodies were only detected in two and S100beta-autoantibodies in one patient. Despite the limited number of samples, these findings suggest a predominant anti-MOG rather than anti-MBP or anti-S100beta autoantibody response in NMO, though no NMO-specific antibody pattern was found, which is in keeping with a widespread acute immune activation, including a strong B-cell response.

Abstract
The aim of this review is to highlight recent observations concerning the pathogenesis of acute and chronic inflammatory demyelinating diseases in the central nervous system. Without attempting to provide a didactic classification or a complete survey, we emphasize the discriminative nature of new clinical, imaging, and immunopathologic data, which, even in the absence of specific molecular markers, modify our views about the nosologic relations among these overlapping clinicopathologic entities. In the light of new findings, multiple sclerosis may represent a spectrum of demyelinating diseases rather than a single entity.

Abstract
We report an elderly woman with multiple sclerosis who showed an extensive cavity formation in the midthoracic cord in addition to multiple abnormal intensity signals in the central nervous system on magnetic resonance imaging (MRI). The cavity decreased in size in response to corticosteroid therapy with an improvement in neurological symptoms. The autopsy demonstrated a slit-like cavity lined with no ependymal cells on the luminal surface in the lower cervical to midthoracic cord, with circumferentially distributed demyelinative lesions, leading to the pathological diagnosis of secondary syringomyelia. In this patient a limited necrosis formed in the spinal cord might have developed into a cavity formation with edematous fluid leading to subsequent episodes of neurological exacerbation.

Abstract
Matrix metalloproteinases (MMPs) are increased in the CSF of patients with multiple sclerosis. Devic's neuromyelitis optica (DNO) is a demyelinating syndrome that involves the optic nerve and cervical cord but differs pathologically from multiple sclerosis. Therefore, we hypothesized that the type of inflammatory reaction that causes MMPs to be elevated in multiple sclerosis would be absent in patients with DNO. CSF was collected from 23 patients with relapsing-remitting or secondary progressive multiple sclerosis, all of whom were experiencing acute symptoms, from seven patients with DNO, and from seven normal volunteers. Diagnoses were made according to current criteria on the basis of clinical manifestations, imaging results and CSF studies. IgG synthesis was increased in the CSF of multiple sclerosis patients but not in that of DNO patients. Zymography, reverse zymography and ELISA (enzyme-linked immunosorbent assay) were used to measure gelatinase A (MMP-2), gelatinase B (MMP-9) and tissue inhibitors of metalloproteinases (TIMPs). Zymograms showed that multiple sclerosis patients had elevated MMP-9 compared with DNO patients and controls (P: < 0.05). TIMP-1 and TIMP-2 levels were similar in all three groups. We conclude that multiple sclerosis patients have higher MMP-9 levels in the CSF than patients with DNO, which supports the different pathological mechanisms of these diseases.

Abstract
We report the neuropathological findings of spinal cord specimens obtained from two patients who had localized myelitis with hyperIgEemia and mite antigen specific IgE (atopic myelitis). Both cases showed mild spinal cord dysfunction, and the gadolinium-enhanced area of the isolated spinal cord lesion observed on MRI was biopsied, respectively. Neuropathologically, both cases showed many perivascular lymphocyte cuffings associated with disrupted vessels, and the infiltration of eosinophils in the spinal cord lesions. Both myelin and axons were lost in the lesions, which were associated with astrogliosis. These findings suggest that an allergic mechanism may play a role in this condition.

Abstract
Imaging considerations for the diagnosis and differential diagnosis of MS are based primarily on results of MR studies of the brain. Recent studies suggest that with current technology, MR imaging of the spinal cord can make important contributions, particularly in cases with equivocal or negative brain MRI studies. Spinal cord MRI may also assume an important role in early diagnosis.

Abstract
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.

Abstract
Acute transverse myelitis (ATM) is a rare disease in childhood and adolescence. It is characterized by paraplegia with or without sensory symptoms and bladder dysfunction, and typically manifests itself over a period of hours to 1 week. This is a report of nine patients who were treated between 1993 and 1996. To exclude treatable conditions, spinal and cranial MRI with and without contrast medium, electrophysiologic tests, and CSF examinations are performed as soon as possible after onset. At present post- or parainfectious inflammation is thought to be the most frequent cause of ATM. Some causes of ATM can be proved only by follow-up examination. The most important differential diagnoses are multiple sclerosis and Guillain-Barré syndrome with its variants. After exclusion of spinal cord compression, and if specific antibiotic treatment is not possible, a 3-day high-dose i.v. steroid pulse therapy is the most promising treatment. Prognosis is variable and residual symptoms are common. A controlled multicenter study is suggested to assess epidemiology, etiology, and prognosis of ATM.

Abstract
We compared clinical and demographic features, MRI findings, and HLA profiles of 57 Japanese patients with multiple sclerosis (MS) between groups with and without oligoclonal IgG bands (OCB) in the cerebrospinal fluid (CSF). Patients with the optic-spinal form of MS (OpS-MS) or acute transverse myelopathy (ATM), which are distinctive and relatively common in Japanese MS, were excluded in this study. The OCB-positive rate was only 56.1% (32/57) among these 57 'conventional' MS patients, of whom clinical features were similar to those of Western MS patients. The demographic features, clinical course, disability, and cerebral abnormalities seen on MRI were similar in the OCB-negative and OCB-positive patient groups. HLA-DR2 antigen, which has been confirmed to be associated with MS in many populations, was more common in the OCB-positive than in the OCB-negative and control groups. Furthermore, DR4 antigen was statistically more common in the OCB-negative patient group. These results raise the possibility that the presence of OCB is related to the immunogenetic background of the patient, and that there may be at least two subpopulations in Japanese patients with 'conventional' MS from the viewpoint of immunogenetics. In one subpopulations, MS is associated with the DR2 antigen, and shows a stronger humoral immune response in the CSF, while in the other MS is associated with DR4, which has a milder humoral response. Further investigations involving more patients are warranted.

Abstract
Although the association between transverse myelitis (TM) and systemic lupus erythematosus (SLE) has been reported previously, it remains a rare clinical condition. Our experience treating three women with lupus TM within a few months is presented. In each patient, spinal cord dysfunction was accompanied by laboratory or clinical evidence of SLE. Further neurologic manifestations, such as optic neuritis, developed in all patients, suggesting other diagnoses, including multiple sclerosis (MS), Devic's syndrome, and lupoid sclerosis. The outcomes for these three women were severe disability, death, and moderate disability, respectively. The severity of outcome did not seem to correlate with the timing or intensity of treatment. Physiatrists should be aware of the potential for neurologic progression in lupus TM, because patients with this condition invariably require rehabilitation.

Abstract
We report a 7-year-old girl with acute disseminated encephalomyelitis subsequent to a mycoplasma infection. She manifested a prolonged state of akinetic mutism, during which EEG revealed well-synchronized spindles. Four months later, she regained consciousness, with no mental deficit, but complete flaccid quadriplegia persisted and magnetic resonance imaging disclosed extensive destruction of the spinal cord. Antibody against galactocerebroside was detected in her serum during the acute phase. The anti-Gal C antibody is suggested to be involved in the pathogenesis of immune-mediated demyelinating diseases in the central nervous system subsequent to mycoplasma infections.

Abstract
PURPOSE To describe the clinical presentation, ophthalmoscopic and fluorescein angiographic findings, and natural history of 14 eyes in nine otherwise healthy, young-to-middle-age adults with idiopathic, acute, multifocal retinitis. METHODS A retrospective review of the clinical and photographic records of nine patients. RESULTS Five of the nine patients reported a flu-like illness 1 to 2 weeks before the onset of visual symptoms. Ophthalmoscopic findings included mild vitritis (11 of 14), mild optic nerve edema (seven of 14), macular star (two of 14) or localized neurosensory retinal detachment (two of 14) caused by adjacent focus of retinitis, and small branch-artery occlusion (two of 14). Fluorescein angiography showed early blocking hypofluorescence with late staining hyperfluorescence of all areas of retinitis. In patients with optic nerve edema, the disk showed late leakage. Specific tests for collagen vascular disorders, as well as systemic syphilis and toxoplasmosis titers, were negative in all patients. Five of six patients with histories of cat exposure tested negative for systemic Bartonella henselae antibodies. One patient with a history of cat exposure refused testing. Clinical courses were self-limited, with complete return of vision without treatment in all but one eye, which developed a juxtafoveal scar and localized traction retinal detachment in an area of prior retinitis. CONCLUSIONS Idiopathic acute multifocal retinitis should be considered in any otherwise healthy, young-to-middle-age adult with acute loss of vision in the presence of multifocal retinitis, particularly when accompanied by an antecedent flu-like illness. Patients with idiopathic acute multifocal retinitis usually have favorable clinical course.

Abstract
Devic's neuromyelitis optica is a rare syndrome characterised by the combination of acute or subacute optic neuritis and transverse myelitis, in some cases considered to be a variant of multiple sclerosis. Mutations of mitochondrial DNA (mtDNA) associated with Leber hereditary optic neuropathy (LHON) have been identified in some patients with multiple sclerosis in whom optic neuritis is a prominent early feature. Using restriction enzyme digestion of mtDNA products amplified by the polymerase chain reaction, the primary LHON mtDNA mutations at positions 3460 bp, 11,778 bp, and 14,484 bp have been excluded in four women with Devic's neuromyelitis optica. A mutation at 4160 bp associated in some LHON families with more widespread neurological disease was also not detected. It is concluded that the primary mtDNA mutations currently associated with LHON are not responsible for the prominence of optic nerve disease in Devic's neuromyelitis optica.

Abstract
PURPOSE Neuromyelitis optica (Devic's disease) is a rare clinical syndrome of unilateral or bilateral optic neuritis (ON) and transverse myelitis (TM) occurring within an 8-week time interval. All reports mainly involve adults and describe a poor neurologic and ophthalmic clinical course without specific attention to their few pediatric cases. The purpose of this study was to develop a clinical profile in the pediatric population. METHODS A retrospective chart review over 15 years revealed nine cases of neuromyelitis optica. A literature search was undertaken and all cases of pediatric neuromyelitis optica were tabulated and analyzed separately. RESULTS The average age of onset was 7 years with a preceding viral prodrome in all patients. The optic neuritis was bilateral in eight of nine patients (89%). Visual loss ranged from 20/30 to light perception. Moderate anterior disc edema was seen in all 17 affected eyes. The clinical course was characterized by a rapid visual and neurologic recovery. The average follow up was 5.3 years, with five patients followed for 6 years or longer. None of the nine patients had any visual or neurologic recurrence or other significant subsequent illness. Visual system follow up showed 20/20 in each eye of all patients with mild optic atrophy, identified in 47% of eyes. CONCLUSIONS Devic's neuromyelitis optica occurs in the pediatric population as a distinct clinical entity with an excellent prognosis for visual and systemic recovery and no future recurrence or long-term sequelae.

Abstract
The inhomogeneous distribution of MS may represent an important clue about the cause of the disease. The prevalence of MS appears to be increasing in many regions of the world, although it is likely that in a majority of regions surveyed, this increase is attributable to differences in ascertainment over the relatively short period that MS has been surveyed worldwide, which is almost exclusively the last 50 years. MS occurs most frequently in regions populated by northern Europeans, and in these areas, it is much more common in the northern European population than in the indigenous populations. MS occurs in relatives of MS patients at a rate 10- to 50-fold greater than in the general population. On average, the absolute risk to a first-degree relative of an MS patient is 2% to 5%, depending on the exact degree of relatedness. Although the mode of transmission is not certain, a multigenic pattern best fits the observed pattern of transmission. A majority of monozygotic twins are discordant for MS, indicating that a major component of MS susceptibility is environmentally determined, although recent observations in adopted relatives suggest that this risk is not transmissible. Rare epidemics of MS involving small numbers of individuals in geographically isolated regions have been reported. A number of migrant studies suggest that the risk of acquiring MS may be altered by migration, although some also support genetic factors. Analytic approaches to address the role of various risk factors include ecologic studies, case-control studies, and cohort studies. Ecologic studies are best suited for addressing risk factors that influence overall population risk, whereas case-control studies are best suited for addressing risk factors that pertain to individuals within a population. If a risk factor is distributed homogeneously in a given population, a case-control study is insensitive to its effect. Improved methodology to diminish the biases inherent in case-control studies and identification of other important risk factors from basic scientific studies undoubtedly will be important for analytic epidemiologic studies of the future. Furthermore, analysis of highly informative populations, such as discordant identical twins and adoptive siblings of MS patients, likely will improve the specificity of case-control studies by minimizing the vast number of potential differences between cases and controls.

Abstract
OBJECTIVES Since Devic's original description of neuromyelitis optica in 1894 there has been much debate regarding its aetiology. A specific cause has been identified in a minority of cases but in most the question has arisen whether or not Devic's neuromyelitis optica is a variant of multiple sclerosis. This study was undertaken to help clarify this issue. METHODS Neuromyelitis optica was defined as (1) a severe transverse myelitis; (2) an acute unilateral or bilateral optic neuropathy; (3) no clinical involvement beyond the spinal cord or optic nerves, and (4) a monophasic or multiphasic illness. The clinical and autoantibody status was documented. Patients underwent CSF examination and MRI of brain and spinal cord. RESULTS Twelve patients, with a mean age of presentation of 35.1 years, were seen. Eleven were women; vision was reduced to counting fingers or worse in 10 patients and seven became confined to a wheelchair. Examination of CSF showed local synthesis of oligoclonal bands in only two patients and a neutrophil pleocytosis in two. A possible aetiology was identified in five: a specific connective tissue disorder (two), pulmonary tuberculosis (one), and possible acute disseminated encephalomyelitis (two). Six had non-specific increases in various autoantibodies. Eleven patients underwent MRI of the brain and spinal cord. In 10 there were diffuse abnormalities involving cervical and thoracic cords with extensive swelling in the acute phase. Brain MRI was normal in five; in five there were multiple deep white matter lesions, and one patient had minor age related changes. CONCLUSION It is proposed that Devic's neuromyelitis optica is a distinctive disorder with some clinical, CSF, and MRI features different from those found in classic multiple sclerosis. In most cases a specific aetiology is not identified, but an immunological mechanism of tissue damage seems likely.
