EMG denervation activity was studied in patients without peripheral neuron disorder but with upper motor neuron lesions. The time course of such central denervation activity, the local distribution and the quantitative relationship between denervation activity and the degree of paresis and spasticity were also studied. A total of 101 patients, who had developed hemiplegia or hemiparesis as a result of a cerebral vascular accident, underwent needle electromyographic examination at regular intervals in proximal and distal muscle groups. The maximum observation time was 1 year. Denervation activity in cases of central paresis first occurred 2-3 weeks after stroke. This could be observed most frequently in the distal arm and hand muscles. In the course of weeks and months the frequency of the denervation activity decreased in parallel with the development of spasticity and the increasing voluntary innervation. The occurrence and the dynamic properties of the denervation activity in cases of central paresis support the assumption of a trans-synaptic degeneration of alpha-motoneurons and of a compensating segmental "sprouting" of afferents.

Motor lesions following herpes zoster are quite common. Hemiparesis, paraparesis, pareses of the facial and other cranial nerves as well as segmental pareses can be observed. We report on a patient suffering from zoster ophthalmicus complicated by paresis of the third cranial nerve. As a cause, a partial brain stem-encephalitis was diagnosed. The patient recovered after antiviral treatment (Aciclovir, Inosiplex).

A 79 years-old man suffered gait disturbance for more than ten years. During the last year the gait worsened. Twenty days after having developed a right hemiparesis, he died from cardiorespiratory failure. Neurological signs were characterized by cogwheel rigidity, distal paresis and amyotrophy of the legs. E.M.G. demonstrated a denervation; ulnar conduction velocity was 38 m/s. The sural nerve biopsy showed a loss of myelinated fibres and no onion-bulb-like formations. A sister (72 years) and two nephews (51 and 39 years) also suffer gait disturbance. The E.M.G.'s demonstrate denervation of the legs. The amplitudes of the motor and sensory nerves are reduced and conduction velocities range between 39 and 59 m/s. Pathologic examination of the propositus showed recent left frontal subcortical infarction, partial neuronal depopulation of the substantia nigra and Lewy inclusions. Microscopic examination of the spinal cord showed integrity of the posterior columns, anterior and posterior spinal roots, cauda equina, and of a thoracic posterior root ganglion. The anterior horns showed a mild gliosis and a slight neuronal depopulation with a few pale or atrophic neurons and very rare neuronophagias. This is believed to be the first autopsy report of a dominant sensory motor neuropathy of the neuronal type. The relative integrity of the spinal cord suggests that the peripheral motor and sensory neurons are affected to the greatest degree at their distal extremity.

A case of interhemispheric subdural hematoma ( ISH ) is presented and discussed. This disorder is a rare form of intracranial hemorrhage, which classically presents as an isolated paresis of one leg or a hemiparesis worse in the leg than the arm. The majority of cases are due to occipital trauma because of the anatomy of the bridging veins. Chronic interhemispheric hematomas are rare since the natural history of these lesions is to spread out over the cerebral convexity. Conservative treatment for ISH may be beneficial unless neurological deterioration necessitates early operative intervention.

Pontine gliomas have been considered to be out of indication for operative treatment. However, in case of a cystic type, evacuation of the cyst alone can possibly extend the survival time of the patient. Since the advent of high resolution CT the nature of the pontine tumor, whether cystic or solid, can be easily differentiated, and cystic ones subjected to operation will be increasing in number. We report a case of cystic pontine glioma associated with von Recklinghausen's disease. The patient showed a remarkable improvement in her neurological status after evacuation of the cyst. A 16-year-old girl was admitted to our clinic with complaints of tinnitus and hearing difficulty of the left ear, progressive gait disturbance and double vision. Neurological examination revealed a sensory disturbance on the left side of the face, left abducens palsy, left facial paresis, left deafness, left cerebellar ataxia, right hemiparesis and right hemisensory disturbance excluding the face. Signs and symptoms of increased intracranial pressure were absent. There were many cafe-au-lait spots and several subcutaneous nodules. CT scan demonstrated a cystic lesion with a mural nodule in the left cerebello-pontine angle. The patient underwent left suboccipital craniectomy, and a puncture of the cyst between the trigeminal and facial-acoustic nerves which were displaced dorsally yielded yellowish fluid. The content of the cyst was evacuated and its wall was widely opened. After the operation the patient showed a remarkable improvement in her neurological deficits only with left deafness remained unchanged. Histological examination showed anaplastic astrocytoma. She was discharged after irradiation of 5000 rads.(ABSTRACT TRUNCATED AT 250 WORDS)

Activation of leg musculature on both sides following a unilateral displacement was studied during stance on separate see-saws, or on stable force-measuring platforms, in patients with spastic hemiparesis and paraparesis. During balancing the movements on the spastic side were damped and the degree of muscle activation reduced. Whereas in healthy subjects the tibialis anterior muscles of both sides were activated, following a unilateral displacement, with the same strength and latency (see-saws 55 ms, platforms 85 ms), in hemispastic patients the EMG responses were delayed (by about 20 to 30 ms) and of reduced strength on the spastic leg, irrespective of whether the unaffected or the spastic side was displaced. In addition, the compensatory movements on the spastic side were damped in both conditions, although the amplitude of displacement was the same bilaterally. Although there was no correlation between the delay and the reduction in EMG response, the latter was correlated with the severity of paresis. In patients with spastic paraparesis quite similar results were obtained with delayed and reduced EMG responses on both sides. It is concluded that in spasticity the impaired regulation of quick compensatory movements is due to a dysfunction of a spinal interneuronal system by which the early EMG responses are mediated. This could be explained by loss of supraspinal control. In addition to the impaired neural activation of leg muscles, changes in the mechanical properties of muscle can be assumed to contribute to the damped movements on the spastic side.

A 49-year-old right handed male, who showed three types of visual disturbance, e. g. hemianopsia, obscuration phenomena and unilateral visuospatial agnosia at different times, was reported. At first, he had hemiparesis, hemisensory disturbance and homonymous hemianopsia on the left side because of multiple stenoses of posterior branches of the right middle cerebral artery. His motor and visual field disturbances improved for several days after onset, but there appeared transient obscuration phenomena on the left visual field. CT scan revealed an abnormal low density area in the right temporo-parietal region. At about 4.5 years after the first attack, he again had hemiparesis and homonymous hemianopsia on the left side. Cerebral angiography showed an occlusion of the right middle cerebral artery. Since his paresis was progressive, STA-MCA anastomoses was performed. Hemiparesis was improved, but homonymous hemianopsia remained. Moreover, at about one year after the second attack, left visuospatial agnosia participated in his hemianopsia. Cerebral angiography showed an additional occlusion in the crural segment of the right posterior cerebral artery. CT scan showed a lesion in the right basal ganglia and temporo-parietal lobe. In most cases, unilateral visuospatial agnosia occurs with hemianopsia. But, in this case, these symptoms occurred at different times. This may indicate the differentiation between unilateral visuospatial agnosia and hemianopsia.

We studied 12 patients with intracerebral hemorrhage in the head of the caudate nucleus. These cases accounted for 7% of a consecutive series of intracerebral hemorrhage. The clinical findings differed from more common varieties of supratentorial hemorrhage. All patients had acute onset of vomiting, headache, stiff neck, decreased level of consciousness, and behavioral changes in a pattern that simulated subarachnoid hemorrhage. Seven patients had gaze paresis and hemiparesis, with or without sensory loss. Two of these seven patients had, in addition, elements of Horner's syndrome. The prognosis for recovery was good. No patient had recurrent hemorrhage or persistent hydrocephalus.

A 62 year-old hypertensive patient with a small left lenticulo-capsular hematoma presented with a right facio-brachial hemiparesis, dysarthria, and a right lingual paresis. The hematoma was limited to the genu and the anterior part of the posterior limb of the internal capsule. The occurrence of this incomplete pseudo-opercular syndrome in relation to a capsular lesion provides evidence for a cortico-hypoglossal projection with predominantly crossed fibers. The situation of the pyramidal tract in the internal capsule is considered.

An acute episode of encephalopathy after the infusion of 16 g methotrexate is reported in a 12-year-old girl with osteogenic sarcoma. The complication occurred during the 11th treatment course, when severe vomiting and diarrhea were followed by a low urine output with consecutive toxic concentrations of methotrexate in serum and cerebrospinal fluid leading to severe systemic and central nervous system toxicity. The onset of the central nervous system toxicity was acute with slurred speech, paresis of the external rectus eye muscles, ataxia, and hemiparesis, and symptoms resolved completely after 30 hours by treatment with calcium leucovorin and forced diuresis. After management of the cerebral and systemic toxicity, high-dose methotrexate treatment could be reinstituted, and was followed by no further complications. In contrast to the transient cerebral dysfunctions, probably caused by embolization of tumor tissue in the early course of high-dose methotrexate treatment, the acute neurologic syndrome observed in the current case after the prolonged use of methotrexate seemed to be related to direct central nervous system toxicity of the drug.
