The authors present the clinico-pathological findings in a member of a family residing in Akita Prefecture located in the north-eastern region of Japan. Four members in three generations of the family developed ataxia. The autopsied patient was a 42-year-old woman, who, at the age of 25, had developed progressive cerebellar ataxia with pyramidal spasticity and increased deep tendon reflexes predominant in the lower extremities. However, she retained fine movement of the hands and fingers and showed no dysarthria until the age of 35. She could no longer walk unassisted at 38 years old. She showed cerebellar ataxia in both hands and legs, dysarthria, bulging eyes, progressive extraoculomotor palsy with nystagmus, bradykinesia, sensory disturbance, and dystonia in the face, upper extremities, and fingers. Deep tendon reflexes were decreased, especially in the lower extremities. Subacute generalized muscular atrophy developed at the age of 39. She became bedridden and died of pneumonia. The clinical diagnosis was Type-2 of the entity known in Japan as Machado-Joseph disease. At neuropathological examination, the brain weight was 1,250 g. The spinocerebellar system including Clarke's column and the spinocerebellar tracts were degenerated, but the cerebellar cortex and inferior olivary nucleus were spared. Slight-to-moderate degeneration was observed in the pontocerebellar system. In the dentate nucleus, most of the neurons showed what is known in Japan as "grumose degeneration", but there was no neuronal loss or gliosis. The hilus of the dentate nucleus and the superior cerebellar peduncle were intact.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a patient whose clinicopathological findings are compatible with those of the case reported by Menzel in 1891. This case was briefly reported by Kinoshita et al in 1967 as hereditary ataxia of Menzel type. But the concept of this disease has been confused, especially in the early investigations for the hereditary olivo-ponto-cerebellar atrophy (OPCA) in Japan. The Kinoshita's patient should be considered as the first Japanese case whose findings are identical with Menzel's report. This report represents a precise study of the case reported by Kinoshita et al. The patient was a 42-year-old Japanese woman. Her mother and one of her brothers suffered from the same disease. She began to experience progressive ataxia at the age of 30. At age 42, she was admitted to another hospital because of inability to walk and mental deterioration. Neurological examination revealed cerebellar ataxia in the extremities and trunk, childish personality change, dementia, diminished deep tendon reflexes with extensor plantar response bilaterally, slowness and hypokinesia in the movement, generalized muscular atrophy, and sensory disturbance prominent in deep sensory. She had no involuntary movement and dysautonomia. She had no retinal degeneration, nystagmus, nor progressive nuclear oculomotor palsy. She died of pneumonia. Neuropathological findings revealed brain weight of 850g.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of familial juvenile parkinsonism with dementia, orthostatic hypotension, neurogenic bladder and constipation was reported. He had been in a good health until the age of 28 when a finger tremor occurred on effort to hold hands in a definite position, and disturbances in gait and speech were noted. These symptoms were relieved by levodopa treatment followed by dyskinesia and motor fluctuations. Three years later, he complained of faintness, constipation and urinary frequency. The neurological examination revealed mentally sound male with masked face, tremor and rigidity in his extremities, and short step gait with lateropulsion. Urodynamic study showed uninhibited bladder. In the following years, orthostatic hypotension, dysuria and urinary retention developed gradually. He became mentally loose and was unable to take medicines appropriately. When in the Nishiojiya Byoin National Sanatorium, he tried to snake out the hospital many times. His parents and a brother suffered from Parkinson's disease and juvenile parkinsonism, respectively, suggesting an autosomal dominant inheritance. On admission to our hospital, he was apathetic. He had masked face, bilateral postural tremor, frozen gait and dyskinesia in the right lower extremity. Little bradykinesia or rigidity was noted. His muscle tone and deep tendon reflexes were decreased but neither muscular wasting, weakness, ataxia nor sensory disturbance was observed. Laboratory data including ceruloplasmin, copper, dopamine-beta-hydroxylase and lysosomal enzyme activities were normal except for mild anemia. A cranial CT scan revealed mild cortical atrophy in the frontal and temporal lobes, but nerve conduction study and cortical evoked potentials showed no abnormality. While in the hospital, his mental functions deteriorated to the state of dementia and orthostatic hypotension became apparent.(ABSTRACT TRUNCATED AT 250 WORDS)

A 48-year-old male was admitted to our hospital because of fever, headache and vomiting. At admission, the level of consciousness was depressed (drowsy) with slight confusion. Extremely miotic pupils, nuchal stiffness, ataxia and myoclonic movements of both upper limbs were observed. The eye movements were almost normal and there was no definite limb weakness or sensory impairment. A few days after admission, his level of consciousness further decreased, and opsoclonus, ataxic breathing and intestinal paralysis appeared. The body temperature fluctuated remarkably ranging from 33.0 degrees C to 39.0 degrees C. The cerebrospinal fluid (CSF) examination revealed lymphocytic dominant pleocytosis, increase of protein and decrease of glucose. Enzyme-linked immunosorbent assay (ELISA) showed increased antibody (IgG) to herpes simplex virus (HSV) in both serum and CSF. The antibody in CSF further elevated at the later examination. Magnetic resonance imaging (MRI) demonstrated high signal intensity areas mainly in the cerebellum and sporadically in the supratentorial subcortical white matter on T2-weighted images. Administration of Gadolinium-DTPA also revealed an additional lesion in the pons. From these findings, he was diagnosed as herpetic encephalitis involving the brainstem and the cerebellum, and acyclovir was administered. Although his initial symptoms and signs started to recover three weeks after admission, he newly developed complete flaccid paraplegia, dysuria and sensory disturbance with the spinal cord level of the 4th thoracic segment. The oligoclonal IgG bands were detected in the cerebrospinal fluid of the convalescent stage.(ABSTRACT TRUNCATED AT 250 WORDS)

We here report a case of Miller Fisher syndrome (MFS) in which serum anti-cerebellar antibody was detected by Western blot analysis. The 32-year-old male studied suffered from diplopia, gait ataxia and sensory disturbance in the distal portion of the upper limbs preceded by cold-like symptoms. Neurological examination on admission revealed that he had external ophthalmoplegia with bilateral ptosis, cerebellar ataxia and areflexia. A cerebrospinal fluid examination showed albuminocytologic dissociation with a protein concentration of 60 mg/dl. Brain CT and MRI showed no significant abnormalities. The patient was diagnosed as MFS, and treated it with two sessions of immunoadsorption plasmapheresis (IAPP). After receiving IAPP therapy, the patient's neurological symptoms and signs were improved. Western blot analysis showed the existence of antibody directed against mouse cerebellum but not against mouse cerebrum, brain stem, and spinal cord in his serum, the level of which was decreased after the IAPP therapy. Serum anti-GQ1b antibody was also elevated. As far as we are aware, there have been no reports showing the existence of anti-cerebellar antibodies detected by Western blot analysis. Though the pathogenesis of MFS remains unclear, our findings suggest that anti-cerebellar antibody detected by Western blot analysis may be caused by cerebellar ataxia in MFS.

We report a 56-year-old female with chronic progressive sensory ataxic neuropathy presenting with alternating skew deviation on lateral gaze in the clinical course. She initially developed dysesthesias in the hands and feet asymmetrically, then gait disturbance developed over several months, and she was admitted to our hospital. Neurological examinations revealed profound deep sensory loss and mild superficial sensory disturbance with the absence of deep tendon reflexes, but muscular strength was completely preserved. EMG showed no evoked response of sensory nerve velocities and normal motor nerves. Sural nerve biopsy showed moderate demyelination with mild infiltration of inflammatory cells, and no vasculitis or onion bulb formation. CSF examination revealed elevation of cell counts and protein with marked intrathecal IgG synthesis and myelin basic protein, but finding of neurosyphillis. Serological examinations did not show any evidence of collagen disease, paraproteinemia, retrovirus infections or Lyme disease. Serum antiganglioside antibodies and anti-Hu antibody were negative. No evidence of malignancy was seen by radiological examinations and assays of tumor markers. In the weeks after admission, gait ataxia progressively worsened, and then she developed alternating skew deviation on lateral gaze, suggesting that the CNS was involved. No responsible lesion was detected on MRI. Corticosteroid administration improved not only the CSF findings, but also the neurologic symptoms, including the alternating skew deviation on lateral gaze. Although the disease entity was not identified, inflammatory demyelinating processes and immune-mediated mechanisms were considered to play important roles.

We describe MR findings in patients with Minamata disease who have been followed for a long time. All patients examined were affected after daily eating of a large quantity of methylmercury-contaminated seafood, from 1955 to 1958, and showed typical neurological findings. On MR images, the visual cortex, the cerebellar vermis and hemispheres, and the postcentral cortex are significantly atrophic in Minamata disease. The visual cortex is slightly hypointense on T1-weighted images and hyperintense on T2-weighted images, probably representing the pathologic changes of status spongiosus. MRI can demonstrate the lesions located in the calcarine area, cerebellum, and postcentral gyri, which are probably related to three of the characteristic manifestations of this disease: the constriction of the visual fields, ataxia, and sensory disturbance, respectively.

Acute infarction confined to the territory of the white matter medullary arteries is a poorly characterised acute stroke subtype. 22 patients with infarction confined to this vascular territory on CT and/or MRI were identified from a series of 1,800 consecutive admissions to our stroke unit (1.2%) between August 1993 and March 1997. 19 patients had small infarcts (< 1.5 cm maximum diameter) and 3 large infarcts (> 1.5 cm). Small infarcts were associated with a history of smoking (69%), hypertension (58%), and hyperlipidaemia (37%), and less frequently with atrial fibrillation (21%). Significant (>50%) ipsilateral carotid stenosis (16%) was a less frequent finding in this group. Patients most commonly presented with weakness and/or sensory disturbance affecting mainly the upper limbs, but dysarthria, dysphasia, and ataxia were also seen. Large infarcts were infrequent in our series, but did not differ significantly from small infarcts with respect to clinical presentation or risk factor profiles (p > 0.05 for all comparisons). The majority of symptomatic patients with white matter medullary infarcts are associated with small (< 1.5 cm diameter) lesions and a risk factor profile consistent with small vessel disease. More data are required to elucidate the mechanism of larger (> 1.5 cm) infarcts. Because of the potential overlap between white matter medullary infarcts and internal watershed infarcts, suggested criteria for each are presented.

Intraspinal tumours in children are rare, the estimated average ratio of spinal to intracranial tumour in the paediatric population is 1:10. We reviewed our experience of paediatric spinal tumours over the period 1992-96. Nineteen patients presented during this time, 12 males and 7 females with the mean age of 7.8 years. The main presenting symptoms were pain, limb weakness, ataxia, sensory disturbance and spinal curvature abnormalities with a mean duration of 10 months. There was a wide variety of tumour types. All underwent a laminectomy with 8 having total tumour excision, 5 partial excision, and 6 had biopsies only. Five patients had extradural lesions and fourteen were intra-dural, four of which were extramedullary and six were intramedullary tumours. There were no major complications of surgery and only one patient had a CSF leak which was repaired. The average hospital stay was 15 days. Seven patients underwent radiotherapy and four had chemotherapy. Four patients are disease free and seven are symptom free after a mean follow-up of 2 years. Four patients died in this series with extensive diffuse tumours.

1. We examined 156 patients 33 years after CO poisoning occurred at the Miike Mikawa Mine, Fukuoka, Japan. The subjects were classified according to age as follows: between 55 and 59 years (n = 14), 60 and 69 years (n = 62), 70 and 79 years (n = 60), and 80 and 87 years (n = 18). The mean age was 69.2 years old. Concerning the duration of coma that occurred soon after the accident, 64 remained comatose from 0 to 6 hours, 46 from 6 to 12 hours and 46 from 12 to 48 hours. 2. Subjective symptoms were observed in 96.8% of the patients. Among them, forgetfulness was noted in 89.7%, followed by irritability in 66.7%, headache in 59.6%, insomnia in 55.8%, limb pain in 46.8%, dull head feeling in 42.9% and dizziness in 36.5%. 3. Intellectual disturbances were observed in 68.6% of the patients, including impression disturbance in 58.3%, memory disturbance in 51.9%, calculation disturbance in 63.5%, thinking disturbance in 61.5% and disorientation in 14.1%. 4. Apathy and disorder of volition and interest which were found in 72.4% were included in personality change because all symptoms persisted for many years. Personality change was classified as follows: weakness of emotion and will (hypobulia) in 54.4%, infantilism in 35.2%, hyperactive, talkactive and lack of inhibition in 18.5%, lack of self-possession and unstable temper in 9.6%, depression in 15.3%, neurosis in 7.6% and schizophrenic state in 2.5%. Among these symptoms of personality change, weakness of emotion and will and infantilism were conspicuous among the patients who remained in a coma for more than 6 hours soon after the accident but showed no relationship with age. 5. Neurological symptoms that were found in 48.7% of the patients were classified as sensory disturbance in 25.6%, peripheral nerve symptoms in 16.0%, pyramidal symptoms in 14.1%, ataxia and cranial nerve symptoms in 7.1%, paroxysmal symptoms in 6.4% and focal symptoms in 4.5%, extrapyramidal symptoms in 21.8% (Parkinsonism in 4.5%, tremor in 10.9% and muscle rigidity in 16.0%) and vegetative symptoms in 37.2%. 6. At the time of investigation, 5 CO poisoning patients were classified as serious cases (3.2%), 20 as comparatively serious (12.8%) medium-degree cases, 28 as comparatively mild (17.9%) medium-degree cases, 37 as comparatively serious (23.7%) mild cases, 42 as comparatively mild (26.9%) mild cases, 24 (15.4%) as having symptoms which were not problematic, and 24 (15.4%) as having symptoms that markedly worsened due to complication. 7. A total of 138 (88.4%) cases had complications were classified as follows: 78 cases (50.0%) of hypertension, 62 cases (39.7%) of cerebral infarction, 24 cases (15.4%) of cardiac disturbance, 21 cases (13.5%) of diabetes mellitus, 14 cases (9.0%) of hepatic disturbance and six cases of silicosis (3.8%). 8. Cranial MRI was carried out for 129 cases (82.7%). Of the abnormal findings identified, cerebral atrophy accounted for 72.0% (93 cases), including moderate and severe cases in 47.2% (61 cases), pallidum lesion for 37.9% (49 cases), lacunar infarction (including cerebral infarction) for 52.7% (68 cases), and hippocampal atrophy for 18.6% (24 cases). Many cases of cerebral atrophy and hippocampal atrophy were observed in patients who remained in the initial coma for more than 12 hours and were 80 years of age or old. The cases of pallidum lesion were observed in patients who remained in the initial coma for more than 6 hours, and no relationship with age was found. The other findings, cerebral atrophy and lacunar infarction showed a slight relationship with age. 9. Among the moderate and serious cases of intellectual disturbance, cerebral atrophy constituted to 62.5%, lacunar infarction 68.7% and pallidum lesion 50.0%. Among the moderate and serious cases of personality change, cerebral atrophy constituted 78.5%, lacunar infarction 35.0% and pallidum lesion 50.0%. Moreover, among extrapyramidal symptoms, pallidum lesion constituted 58.6%, cerebral atrophy 55.1% and lacun
