A young epileptic presented with spasticity as well as ataxia, diplopia and nystagmus; his serum phenytoin level was very high. All the abnormal signs disappeared after withdrawal of phenytoin. Spasticity, hyperreflexia, and clonus are features of phenytoin intoxication, present in this case, which are not commonly seen, and which have rarely been mentioned previously in the literature.

The orthopaedic surgeon is often the first consultant to whom a patient with syringomyelia is referred. The disease is not as rare as he may suppose, but its early presenting features are very variable; if he relies solely on such familiar features as pes cavus and scoliosis, he may well miss the diagnosis. The commonest presenting symptom is pain in the head, neck, trunk or limbs; headache or neckache made worse by straining is particularly significant. A history of birth injury also may suggest the possibility of syringomyelia, especially if any spasticity subsequently worsens. Neurological features which may be diagnostic include nystagmus, dissociated sensory loss, muscle wasting, spasticity of the lower limbs or Charcot's joints. Radiographic features include erosion of the bodies of cervical vertebrae and widening of the spinal canal; if, at C5, the size of the canal exceeds that of the body by 6 millimetres in the adult, pathological dilatation is present. The presence of basilar invagination or other abnormalities of the foramen magnum, of spina bifida occulta and of scoliosis are further pointers. Thermography is a useful way of showing asymmetrical sympathetic involvement in early cases. A greater awareness of the prevalence of syringomyelia may lead to earlier diagnosis and to early operation, which appears to hold out the best hope of arresting what is all too commonly a severely disabling and progressive condition.

A systematic search for cases of adult-onset hereditary ataxia was conducted on location in Scotland. The investigation resulted in the discovery of eight pedigrees with 42 patients of whom 16 were alive in 1975. Nine patients were examined by the authors and recent hospital records were available on the remaining seven. The clinical features were quite variable. In declining order of frequency, findings were gait and limb ataxia, dysarthria, hyperreflexia, extrapyramidal motor disturbances, impaired vibratory sense, spasticity, defects of extraocular movements and nystagmus, reflex depression, Babinski signs, impaired joint position sense, muscle weakness, optic atrophy, and mental abnormalities. Foot deformity occurred only once. Inheritance was compatible with autosomal dominant transmission, but complicated by consanguinity in two families. The minimum prevalence was calculated as 0.31/100,000. Autopsy in two members in one family revealed olivopontocerebellar degeneration.

A rare case of intramedullary schwannoma of the spinal cord has been reported, The patient was a 30-year-old woman, who began to notice weakness in her right leg approximately 6 months prior to admission, followed 4 months later by numbness and weakness of the right arm. The above symptoms were progressively getting worse, and she was admitted to Hokkaido University Hospital on February 23, 1974. Neurological examination revealed slow speech, bilateral horizontal nystagmus, absent gag reflex and weakness of right trapezius muscle. Spasticity was noted in 4 extremities, in addition to right hemiparesis. All deep tendon reflexes were hyperactive, right more than left, with bilateral Hoffmann's and Babinski's signs. Vibration sense was diminished below the level of bilateral iliac crests. A tumor around the foramen magnum was suspected, however plain skull and neck, laminogram of cervical spines, vertebral arteriogram, fractional pneumoencephalogram and myodil myelogram failed to disclose abnormalities. Manometric Queckenstedt test showed a partial block on flexion, with CSF protein of 56 mg/dl. Air myelogram clearly visualized the presence of an intramedullary tumor at the level of the medullo-spinal junction. Subtotal removal of the intramedullary tumor at C1 was performed, which proved to be a schwannoma histologically. 14 such cases are reported in the literature and summarized on Table I, including our case. Clinical features of tumors around the foramen magnum are fairly complexed, and some radiological examinations might not be conclusive. It is stressed that air myelogram is extremely valuable in the diagnosis of lesions around the foramen magnum.

In nine cases of phencyclidine hydrochloride poisoning, early signs of overdose included drowsiness, nystagmus, miotic pupils, blood pressure elevation, increased deep tendon reflexes, ataxia, anxiety, and agitation. In more severe cases, seizures, spasticity, and opisthotonos were seen in addition to deep coma and respiratory depression. Treatment included removal by emetics or lavage, hydration, and a quiet, reassuring environment. Spasticity, agitation, and ocular manifestions responded to diazepam. Psychiatric intervention was instituted after the patients were stable and no longer agitated.

Four pedigrees of Machado-Joseph disease (MJD) were reported. Main clinical features of 21 patients in these pedigrees were cerebellar ataxia, limb spasticity, gaze nystagmus, facio-lingual twitchings, and external ophthalmoparesis. Amyotrophy, hypokinesia, or dystonia were manifested with advance of the illness. In patients with younger onset age, such extrapyramidal signs were dominated. Neuropathological study of one autopsied case disclosed that there were degeneration of spinocerebellar tract, anterior horn cells, pontine nuclei, dentate nucleus, red nucleus, substantia nigra, internal segment of globus pallidus, subthalamic nucleus, and motor nuclei of brain stem; neurons of cerebellar cortex and inferior olivary nucleus were preserved. From these clinical and pathological features, these 4 pedigrees satisfied the criteria of MJD, and were differentiated from hereditary olivopontocerebellar atrophy. Currently, MJD is accepted as a new entity of hereditary spinocerebellar ataxias. However, there are still controversies as to whether Azores-Portuguese MJD and Japanese MJD are identical disorder. Furthermore, the nosological relationship between MJD and a number of similar cases, as reported historically under the diagnosis of Brown type ataxia or Marie's ataxia, has not been clearly established. From reviewing such cases critically, pathological and clinical features of our cases are so similar to those of the latter, indicating that the probably identical genetic disorder has been classified under the different categories.

Experience is described in 25 patients from southern New England with Machado-Joseph Disease, examined serially at annual screening clinics. The disorder is dominantly inherited, with a wide range of phenotypic variation. Core clinical features described include ataxia, nystagmus, dysarthria, facial fasciculations, and lid retraction, producing a characteristic staring expression. In addition, young onset patients have spasticity, extrapyramidal rigidity, and dystonic manifestations. Late onset patients often have distal atrophy and sensory loss. Postural instability is often an early feature. We discuss the distinction of this entity from the olivopontocerebellar atrophies.

Spinocerebellar ataxial 1 (SCA1) is the locus name of autosomal dominant olivopontocerebellar atrophy (OPCA), and is assigned to the short arm of chromosome 6. The tight linkage between SCA1 and D6S89 has recently been reported. In order to examine possible locus heterogeneity, we studied linkage for D6S89 to disease loci in 16 pedigrees of dominant OPCA. D6S89 polymorphism was analysed with PCR amplification of genomic DNA by using specific oligonucleotide primers. Lod scores were computed by LIPED program with the correction of age-dependent penetrance. Homogeneity test was performed by using HOMOG program. Fifteen out of 16 pedigrees were informative to D6S89. Among them, 7 pedigrees showed positive and 8 pedigrees showed negative lod scores throughout all recombination fractions. Homogeneity testing disclosed that approximately 55% of pedigrees are linked to D6S89, and others were not linked. Our results provide evidences that dominant OPCA in Japan are genetically heterogenous. At now, it has been still unknown whether there are any clinico-pathological differences among OPCA genotypes. Based on the alpha-constant from homogeneity testing, we divided our pedigrees into linked-pedigree (SCA1) and nonlinked-pedigrees (nonSCA1). Then, clinical features were compared between these two groups. Hyperactive DTR was more common in SCA1 than nonSCA1 group. On the other hand, hypoactive DTR was more significantly dominated in nonSCA1 than SCA1. Slow saccade and Babinski sign were common in both groups. Although not statistically significant, nystagmus, exteral ophthalmoparesis, mydriasis, ptosis, facio-lingual twitching, and limb spasticity were more frequently observed in SCA1 than nonSCA1. These results indicate that there are possible correlation between disease genotype and phenotype.(ABSTRACT TRUNCATED AT 250 WORDS)

Familial spastic paraplegia (FSP) was recorded in three families. The pattern of familial transmission and the onset in the second and third decade of life strongly suggested autosomal dominant inheritance. FSP in this series showed the consistent, classical, clinical features with some inconstant findings (nystagmus, dysarthria, posterior column involvement). Baclofen for the treatment of spasticity is beneficial in this condition and genetic counselling should be considered.

The patient, a 31-year-old married woman, noticed spasticity on walking at the age of 19 accompanied by ataxia, dysarthria and dysphagia. Facial twitching and dystonic movement of extremities have been observed since age 27. A sister of her father showed the similar ataxia and dysarthria, and expired of pneumonia at the age of 45. On admission at the age of 29, neurological examinations revealed nystagmus, marked spasticity with pathological reflexes and clonus, cerebellar ataxia, dysarthria and dysphagia, diffuse muscle wasting, fasciculation in facial musculature, and generalized slow dystonic movement. By neuro-otological studies bilateral MLF syndrome with upward gaze limitation and decreased velocity of saccadic eye movement were detected. Surface EMG at rest showed a dystonic discharges on the extremities. Needle EMG disclosed a systemic neurogenic change with reduced interference and high amplitude potentials. Atrophy of the brainstem was remarkable on the cranial CT and MRI. These abnormal eye movements, especially bilateral MLF syndrome and generalized dystonia seem to be quite unusual in the variety of spinocerebellar degenerations. On reviewing detected clinical descriptions on Joseph disease this case can be probably included.
