ABSTRACT

Muscle hypertrophy in neurogenic disorders is an uncommon phenomenon which has been reported in various conditions: hereditary or acquired anterior horn cell diseases, essentially S1 radicular compressions, and polyneuritis generally of a demyelinating type. We report two cases of denervating disease with muscle hypertrophy. The first was an S1 radiculopathy, and the second a compression with ischemia of the spinal cord by herniation of the D11-D12 disc, and showing partial improvement after surgery. In both cases, electrophysiological examination of the hypertrophic muscles revealed abnormal activities identified as complex repetitive discharges. In the second case they were associated with a syndrome of continuous motor unit activity. Such activities are rare in peripheral nerve involvement. However they have quite often been recorded in cases of neurogenic muscle hypertrophy and may therefore be partly responsible for the development of the hypertrophy.

ABSTRACT

The authors describe the case of a 12 years old boy suffering from an epilepsy with complex partial seizures evolving to a syndrome of epilepsy with continuous spikes-waves during sleep. A dramatic improvement follows clobazam introduction in the treatment. The originality of this case report and the possible mechanism of action of clobazam are discussed.

ABSTRACT

Thirty patients with the Lennox-Gastaut syndrome presenting one or more status epilepticus (the first before age 15) were studied. Triggering factors, semiology, duration, severity and EEG features were considered. A comparison was made between this group of patients and another group having the Lennox-Gastaut syndrome but without status. No significant difference appears in the long-term prognosis, even when status were prolonged. Only three patients died during a status. For this reason the authors recommend prudence and avoidance of very strong treatment. In their experience, intravenous diazepines, intravenous phenytoin and intramuscular ACTH were the most effective drugs.

ABSTRACT

In two cases with recurrent palsies, the results of electrophysiological studies led to nerve biopsy showing typical tomacula. The first case was an inherited neuropathy with liability to pressure palsies. The second case was an apparently sporadic painless recurrent brachial neuropathy. Electrophysiological alterations were diffuse and sensory fibres of the median nerve between index and wrist were the most involved. Conduction blocks were observed without palsy in narrow anatomical passageways where nerve compressions are frequent (ulnar nerve at the elbow, peroneal nerve at the fibula). A compression by a neighbouring anatomical structure could make the prognosis worse and justify nerve decompression. The nerves with slowest conduction have the most important risk of palsy and the patients should be given advice to avoid their compression.

ABSTRACT

A 20 year old woman with complex partial seizures from childhood developed a stuporous state when her anticonvulsant therapy was substituted by VPA. She recovered when treated orally with clonazepam. This case was compared with others in the literature for which the origin of the stuporous state have been hypothesized.

ABSTRACT

A 23-year-old man presented with a history characterized by a myoclonic syndrome developing over a period of seven years. Predominant symptoms were intention and activity myoclonus, generalized epileptic seizures occurring infrequently from the age of 20, a slowly progressive cerebellar syndrome first apparent at 19 years, and the sudden onset of loss of visual acuity at 19, which then partially regressed; optic atrophy and clinical and campimetric signs were suggestive of Leber's disease. Intellectual ability was not affected. E.E.G. records showed generalized spike-waves with photosensitivity, progressive reduction in basal rhythm, and sleep organization disturbances with focal abnormalities. Obvious clinical signs of muscle disease were lacking but muscle biopsy confirmed the presence of a mitochondrial myopathy (ragged-red fibers). An indefinite history of familial neurological disease was obtained. Diagnosis was established as myoclonic cerebellar dyssynergy with spastic hereditary ataxia and Leber's disease. Their association with a mitochondrial myopathy has been previously reported by Tsairis et al, Fukuhara et al, Fitzimons et al (familial case), and Niedermeyer et al (sporadic case). In spite of the non-specific nature of associated mitochondrial abnormalities, all these cases would appear to correspond to a single nosological entity.
