A 66-year-old female suffering from HTLV-1 associated myelopathy (HAM) for more than 30 years was hospitalized because of memorial impairment, deafness, dysarthria, dysphagia, and complete paraplegia. She first noticed stiffness and weakness of the right leg at 35 years of age. Gait disturbance was slowly progressed and complete paraplegia developed 18 years later. Neurological examinations on admission revealed that she was bedridden with decubitus, mental deterioration (pre-dementia of subcortical type), bilateral optic nerve atrophy, severe sensory-neural deafness, dysarthria, complete paraplegia, and marked neurogenic bladder. Laboratory data showed mild normocytic anemia and moderate diabetes mellitus. Anti-HTLV-1 antibody titers in serum and CSF were 78,192X and 1,024X, respectively (PA method). Serum levels of soluble IL-2 receptor was markedly elevated (2,200 U/ml). Peripheral blood lymphocytes showed spontaneous proliferation when cultured for 5 days (3H-thymidine uptake; 45,285 cpm/5 X 10(4) cells). MRI examinations of the spinal cord disclosed a predominant atrophy of lower thoracic cord without any compressive lesions. Brain MRI showed diffuse high intensity lesions of the periventricular area on T2 weighted images. Such abnormalities were predominantly found in fronto-parietal region and were quite similar to those of leuko-ariosis. Single photon emission CT using 123I-iodoamphetamine showed hypoperfusion of cerebral white matter on delayed image. It has been reported that intellectual impairment and brain atrophy are not usually seen in HAM patients. The present case, however, shows that such abnormalities of the central nervous system could occur in HAM patients with a long duration of illness.

Neurologic manifestations, afflicting up to 70% of SLE patients, include psychosis, seizures, chorea, neuropathies, and stroke. MRI is useful in evaluation of lupus patients and several reports have documented cerebral atrophy or focal hyperintensities. We report an unusual MRI appearance in a 56-year-old woman with SLE, diagnosed on the basis of pleuritis, lymphopenia, anti-DNA antibodies, and neurologic involvement. She reported recent onset of Raynaud's phenomenon and generalized macular rash. She presented after two months of gradual deterioration with memory loss, flattened affect, dysphagia, dysarthria, anomia, and somnolence, without focal neurologic signs. Investigations included elevated ESR, reduced complement, normal CSF without oligoclonal bands, negative viral serology, normal hormone and vitamin levels, normal renal and hepatic function. Neuropsychologic testing showed widespread impairment (WAIS-R: FSIQ-63; WMS-69; DRS-98; RCPM-14; WAB AQ-78.8). CT was normal but MRI showed strikingly symmetric, confluent hyperintensities extensively involving cerebral and cerebellar white matter on T1 and T2 weighted scans. Basal ganglia and subependymal and subcortical white matter were spared. Treated with prednisone, the patient made a gradual, but incomplete, recovery. These MRI findings may reflect widespread vasculopathy or direct immunologic brain insult with or without immunologic blood-brain barrier disruption.

We reported two cases of brothers demonstrating oculopharyngeal muscular dystrophy (OPMD). The cases had consanguineous parents and five healthy siblings, which suggested the autosomal recessive inheritance. The initial symptom was slowly progressive blepharoptosis with onset in the third decade. On examination, total external ophthalmoplegia was observed in both patients. Additionally, the elder, a 57-year-old man, exhibited dysarthria, dysphagia and muscular weakness with atrophy of the face, bilateral proximal upper limbs and diffuse lower limbs. The younger brother, a 55-year-old man, displayed muscular weakness and atrophy distributed in the face and four limbs. Muscle biopsy of both cases revealed rimmed vacuoles and spheroid bodies in the atrophic and normal-sized fibers. Biochemical study of the biopsy specimens of the elder brother disclosed the myophosphorylase activity reduced to about 40% of the normal value, although in the younger brother, that activity was normal. OPMD is usually inherited in the autosomal dominant mode, and autosomal recessive OPMD is rare. The onset age of our cases was younger than that of the autosomal dominant OPMD. There were some differences in the clinical manifestation between the presented cases, which could be interpreted as phenotypic variation. The elder brother was thought to be associated with McArdle's disease.

A 28-year-old woman developed central pontine myelinolysis (CPM) following severe hyponatremia. Radiological examinations demonstrated a characteristic pontine lesion of CPM. Her neurological symptoms (drowsiness, emotional lability, dysarthria, dysphagia, and quadriparesis) were improved dramatically by treatment with thyrotropin-releasing hormone (TRH) and rehabilitation. However, results of repeat computed tomographic (CT) scans of the brain remained unchanged. This case therefore suggests that TRH may be beneficial for the treatment of CPM, and that CT findings appear to be a limited prognostic indicator for CPM.

This is the first large scale case series of motor neurone disease (MND) in Thailand. Seventy-seven patients were identified between 1978 and 1984 at Siriraj Hospital Medical School, Bangkok, Thailand. Fifty-five patients were male (71.43%) and the mean age of the patients was 51.55 (SD 14.26) years with the range of 17 to 78 years. Clinical classification of MND was categorized as progressive bulbar palsy (PBP), 26 patients (33.77%); amyotrophic lateral sclerosis (ALS), 42 patients (54.54%); and progressive spinal atrophy (PSA), 9 patients (11.69%). The mean age of PBP, ALS and PSA were in the order of 57.61 (SD 12.09), 52.81 (SD 11.18), and 28.11 (SD 9.44) years. Progressive spinal atrophy group was younger than PBP and ALS groups significantly at the P-value less than 0.05 by analysis of variance and Duncan tests. Fifty-three patients (72.60%) were resident in Bangkok and the central part of Thailand. The main presenting symptoms were wasting of the small muscles of both hands, leg weakness, and speech and/or swallowing difficulties. These symptoms were found in 62 patients (81.58%). Nearly half of the patients (48.68%) came to our care within six months of onset, 22.8 per cent presented with asymmetry of motor wasting, while limb and trunk fasciculation was seen in 73.61 per cent. Dysarthria, dysphagia and tongue fasciculation were recorded as 51.32, 48.68, 60.53 per cent respectively. Exaggerated deep tendon reflexes were noted as 65.79 and 80.26 per cent over the upper and lower limbs, while Babinski sign was elicited in only 23.3 per cent of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

This report describes a rare complication after the resection of a tumor of the posterior fossa, the "one-and-a-half" syndrome. The one-and-a-half syndrome is a disturbance of horizontal eye movements in which patients have lateral gaze palsy in one direction and internuclear ophthalmoplegia in the other direction. The patient was a 54-year-old woman who developed headaches, diplopia, and blurred vision over 6 months. Computed tomographic scans and magnetic resonance imaging demonstrated an enhancing, mixed density, midline mass of the cerebellum. After a resection of the mass, an anaplastic astrocytoma, the patient complained of more severe diplopia and facial weakness. An examination disclosed a left one-and-a-half syndrome, left peripheral facial paralysis, dysarthria, dysphagia, mild left hemiparesis, dysmetria of the left upper limb, and truncal ataxia. The brain stem showed no abnormalities on postoperative computed tomographic scans. After 4 months of follow-up, the one-and-a-half syndrome had not improved, even though other signs had improved or resolved. This syndrome is caused by damage to structures within the pontine tegmentum: the medial longitudinal fasciculus, the ipsilateral paramedian pontine reticular formation, or the ipsilateral abducens nucleus. Multiple sclerosis and brain stem infarction are the most common causes of the one-and-a-half syndrome. Less frequently, it is caused by primary and metastatic tumors of the brain stem and cerebellum. Rarely, the one-and-a-half syndrome can develop postoperatively after the removal of tumors of the posterior fossa. The mechanism of pontine tegmental injury remains unknown.

Nineteen cases are described, including 12 cases from three different families and 7 nonfamilial cases, in which multisystem neurological disease was associated with acanthocytosis in peripheral blood and normal plasma lipoproteins. Mild acanthocytosis can easily be overlooked, and scanning electron microscopy may be helpful. Some neurologically asymptomatic relatives with significant acanthocytosis were identified during family screening, including some who were clinically affected. The mean age of onset was 32 (range 8-62) yrs and the clinical course was usually progressive but there was marked phenotypic variation. Cognitive impairment, psychiatric features and organic personality change occurred in over half the cases, and more than one-third had seizures. Orofaciolingual involuntary movements and pseudobulbar disturbance commonly caused dysphagia and dysarthria that was sometimes severe, but biting of the lips or tongue was rarely seen. Chorea was seen in almost all symptomatic cases but dystonia, tics, involuntary vocalizations and akinetic-rigid features also occurred. Two cases had no movement disorder at all. Computerized tomography often demonstrated cerebral atrophy. Caudate atrophy was seen less commonly, and nonspecific focal and symmetric signal abnormalities from the caudate or lentiform nuclei were seen by magnetic resonance imaging in 3 out of 4 cases. Depression or absence of tendon reflexes was noted in 13 cases and neurophysiological abnormalities often indicated an axonal neuropathy. Sural nerve biopsies from 3 cases showed evidence of a chronic axonal neuropathy with prominent regenerative activity, predominantly affecting the large diameter myelinated fibres. Serum creatine kinase activity was increased in 11 cases but without clinical evidence of a myopathy. Postmortem neuropathological examination in 1 case revealed extensive neuronal loss and gliosis affecting the corpus striatum, pallidum, and the substantia nigra, especially the pars reticulata. The cerebral cortex appeared spared and the spinal cord showed no evidence of anterior horn cell loss. Two examples of the McLeod phenotype, an X-linked abnormality of expression of Kell blood group antigens, were identified in a single family and included 1 female. The genetics of neuroacanthocytosis are unclear and probably heterogeneous, but the available pedigree data and the association with the McLeod phenotype suggest that there may be a locus for this disorder on the short arm of the X chromosome.

We report a case of synchronous positive and negative myoclonus following pontine hemorrhage. Constant synchronous jerking of the eyes, tongue, face, mandible, larynx, pharynx, and diaphragms persisted during sleep. Jerking of limb muscles occurred during volitional activities, but not at rest. Inability to sustain glottic adduction during phonation contributed to severe dysarthria. Electromyography (EMG) revealed positive myoclonus of the branchial musculature with synchronous negative myoclonus in a generalized distribution. Treatment with trazodone reduced the ocular myoclonus but worsened the dysphagia. We suggest that a single neural rhythm generator may produce both positive and negative myoclonus.
