1/745. Biofeedback training to overcome poststroke foot-drop.

    The technique has exciting potential for elderly hemiplegic patients, even those who are confined to a nursing home. There are limiting factors, of course; the method is time-consuming and the initial outlay for equipment is high. But the rewards can be well worth the time, effort, and cost involved. The recovery potential of some geriatric patients after a cerebrovascular accident may seem bleak because of multiple disabilities, e.g., paralysis, delayed reflexes, aphasia. Fortunately, these disorders do not necessarily decree failure of biofeedback training. Neither does advanced age. The strongest component in success is motivation. A case in point is the 82 year old woman described here who had been hemiparetic for seven years. With biofeedback training, she gained--and maintained--muscle strength. ( info)

2/745. Juvenile form of dihydropteridine reductase deficiency in 2 Tunisian patients.

    Two brothers are described who had juvenile-onset DHPR deficiency. Both were considered normal until six years of age when they developed a fluctuating and progressive encephalopathy combining mental retardation, epilepsy, pyramidal, cerebellar and extrapyramidal signs. ( info)

3/745. akinetic mutism after fourth ventricle choroid plexus papilloma: treatment with a dopamine agonist.

    BACKGROUND: akinetic mutism is a behavioral state wherein a patient seems to be awake but does not move or speak. Several patients are reported to have developed mutism after posterior fossa surgery. We present a patient who developed akinetic mutism after total excision of a choroid plexus papilloma of the fourth ventricle, and who was treated with bromocriptine. CASE DESCRIPTION: An 18-year-old woman was admitted with akinetic mutism, which had developed 6 days after posterior fossa surgery. She had had no neurologic deficit in the first 5 days after surgery and could communicate with her family. Despite antioedematous therapy and daily lumbar punctures to drain cerebrospinal fluid, there was no clinical improvement after she entered the akinetic mute state. brain magnetic resonance revealed ventriculomegaly; brain single photon emission computed tomography revealed bilateral reduction of perfusion in the frontal region. Because daily lumbar drainage did not result in clinical improvement, shunt placement was not considered. bromocriptine therapy was begun at a dose of 2x2.5 mg; 24 hours later, the patient started to speak and move her upper extremities. Further improvement occurred over the following week when the dose was increased to 3x2.5 mg. bromocriptine was replaced with a placebo to determine whether the neurologic improvement was caused by the medicine. The patient's neurologic status deteriorated progressively; therefore, bromocriptine was restarted and she was discharged from the hospital. During the 6 months of follow-up, the patient has remained in good health. CONCLUSIONS: The etiology of akinetic mutism is not clear. Monoaminergic pathways, particularly dopaminergic cell groups, are most probably involved in this syndrome, because bromocriptine has a dramatic effect on these patients, as demonstrated in our case.

4/745. Hypotonia, congenital nystagmus, ataxia, and abnormal auditory brainstem responses: a report on the first white patient.

    A white Italian boy, aged 5 years and 8 months, is reported with failure to thrive, hypotonia, truncal ataxia, psychomotor retardation, and congenital horizontal pendular nystagmus with only waves I and II on auditory brainstem responses. Our patient's clinical picture resembles that previously reported in 10 male Oriental patients. He did not manifest spastic diplegia by the age of 2 years, as did the subjects reported in the literature, but knee-jerk hyperreflexia was evident at the most recent clinical reevaluation. Serial brain MRI studies revealed a cystic brain lesion and peritrigonal hyperintensities with no brainstem abnormalities. To date, no other child with a similar syndrome has been described either in europe or in America. The clinical features of this condition are consistent and characteristic. A definitive diagnosis is achieved by demonstrating the absence of all waves following wave I or wave II on auditory brainstem responses as early as 3 months of age. Due to the predominance of males, the occurrence in siblings, the early age at onset, the non-progressive course, and the characteristic auditory brainstem response findings, the syndrome may have a genetic origin and be attributable to a dysgenetic brainstem lesion.

5/745. Osmotic demyelination syndrome with two-phase movement disorders: case report.

    Osmotic demyelination syndrome (ODS) is characterized by regions of demyelination throughout the brain, which are most prominent in the pons. This demyelinating disease is associated with electrolyte disturbances and typically occurs in patients who are alcoholic or malnourished. movement disorders are not frequently recognized in patients with ODS. This report describes a 22-year-old woman with ODS after correction of profound hyponatremia. The main neurologic symptom was two-phase movement disorder. First, she had acute onset dystonia, then the movement disorder transformed to generalized rigidity and tremors in the delayed second phase. magnetic resonance imaging in the first phase revealed demyelinating lesions in the central pons, bilateral thalami and basal ganglia. In the second phase, the previous myelinolysis had been partially resolved. The clinical course of the two-phase movement disorder did not correlate with the resolving feature of neuroradiologic findings. During the second-phase movement disorder, the patient had a good response to propranolol and trihexyphenidyl. ( info)

6/745. 18Fluoro-2-deoxyglucose (18FDG) PET scan of the brain in type IV 3-methylglutaconic aciduria: clinical and MRI correlations.

    The clinical, 18fluorodeoxyglucose positron emission tomography (18FDG PET) and the magnetic resonance imaging (MRI) brain scan characteristics of four patients diagnosed to have 3-methylglutaconic aciduria were reviewed retrospectively. The disease has a characteristic clinical pattern. The initial presentations were developmental delay, hypotonia, and severe failure to thrive. Later, progressive encephalopathy with rigidity and quadriparesis were observed, followed by severe dystonia and choreoathetosis. Finally, the patients became severely demented and bedridden. The 18FDG PET scans showed progressive disease, explaining the neurological status. It could be classified into three stages. Stage I: absent 18FDG uptake in the heads of the caudate, mild decreased thalamic and cerebellar metabolism. Stage II: absent uptake in the anterior half and posterior quarter of the putamina, mild-moderate decreased uptake in the cerebral cortex more prominently in the parieto-temporal lobes. Progressive decreased thalamic and cerebellar uptake. Stage III: absent uptake in the putamina and severe decreased cortical uptake consistent with brain atrophy and further decrease uptake in the cerebellum. The presence of both structural and functional changes in the brain, demonstrated by the combined use of MRI and 18FDG PET scan, with good clinical correlation, make the two techniques complementary in the imaging evaluation of 3-methylglutaconic aciduria.

7/745. Differential clinical and motor control function in a pair of monozygotic twins with Huntington's disease.

    We report a pair of monozygotic Huntington's disease (HD) twins who, although sharing identical CAG repeat lengths, not only present with marked differences in clinical symptoms but also behavioral abilities as measured by our experimental procedures. Both HD twins and two healthy control subjects were tested twice over 2 years. Patient A was generally more impaired at a motor level, whereas Patient B showed greater attentional impairment; Patient B, however, showed more progressive deterioration. The control subjects' performance remained consistent over the 2-year interval. Patient A clinically had the more hyperkinetic hypotonic variant of the disease, whereas Patient B, who was the more impaired, presented with a more hypokinetic hypertonic (rigid) variant. The influences of epigenetic pre- and postnatal environmental factors should not be ignored. ( info)

8/745. Gingival fibromatosis combined with cherubism and psychomotor retardation: a rare syndrome.

    Gingival fibromatosis is frequently an isolated condition, but rarely associated with some uncommon syndromes. This paper describes an 11-year-old patient with pronounced gingival enlargement, cherubic facial appearance, and psychomotor retardation and discusses the major aspects of the case. The most striking finding orally was the presence of grossly hyperplastic gingiva, which completely covered all teeth except the occlusal surfaces of some teeth. The swelling in the lower part of the face and the appearance of sclera beneath the iris suggest cherubism. The diagnosis was confirmed by the detection of giant cell regenerative granuloma and perivascular eosinophilic particles and osteoclasts after biopsy of the mandible. In this case, surgery was the only effective way to treat the patient. A full-mouth gingivectomy procedure was performed under general anesthesia in 2 stages. The case was followed for 12 months and no recurrence was seen. An appropriate oral hygiene regimen was established. ( info)

9/745. Facial dyskinesia induced by auditory stimulation: a report of four cases.

    INTRODUCTION: The Vibroacoustic disease (VAD) is an occupational pathology induced by long-term (>10 yr) exposure to large pressure amplitude (> or = 90 dB SPL) and low frequency (< or = 500 Hz) noise. During studies contributing to the characterization of VAD, abnormal facial movements induced by repetitive auditory stimuli were observed in one individual employed as an aeronautical mechanic. The goal of this study was to investigate the existence of movement disorders triggered by auditory stimuli in a group of VAD-diagnosed patients. methods: Sixty VAD patients received auditory and median nerve stimulation. Simultaneously, EEG monitoring was performed. RESULTS: Abnormal myoclonus movements were triggered by auditory stimuli in four patients. EEG recordings were normal in all 60 patients. Stimulation of the median nerves did not trigger any abnormal movements. CONCLUSION: These data suggest that this facial dyskinesia has a subcortical origin. ( info)

10/745. A novel method for locomotion training.

    This article describes a novel therapeutic system for locomotion training and learning for patients with a wide range of neurological and musculoskeletal disorders. The technique embraces the notion that locomotion therapy should be goal oriented and task specific. The task specificity includes a partial weight-bearing device that permits the posture/equilibrium, movement, and weight-bearing components of gait function to operate concurrently, even in patients with serious deficits. In addition, it allows interaction with therapists and others to facilitate locomotion control, particularly during the early stages of gait therapy. Neurobiological bases for this technique and early clinical results are discussed, and two case studies of patients with traumatic brain injury (TBI) are presented. Although well-designed efficacy studies are needed, clearly this therapeutic approach to locomotor disorders among TBI patients meets the various criteria for recovery of gait function established in this article.
