[Meningoradiculitis after injection of an antirabies vaccine. A vaccine from human diploid cell culture].

We report the case of a 45-year old farmer who developed meningoradiculitis after preventive anti-rabies vaccination with a vaccine obtained from human diploid cell culture. Two weeks after the second injection of vaccine, the patient complained of sensory symptoms in the right half of his body. These symptoms spontaneously regressed.

[Mitochondrial encephalopathy affecting only the central nervous system].

A 32 year-old diabetic woman presented with an acute coma followed by epileptic seizures, aphasia and constructive apraxia. No ischemic lesion was demonstrated by CT scan and carotid angiograms. The other investigations showed sensorineural hearing loss, retinal degeneration, calcifications of the basal ganglia and lactic acidosis.

Type 2 fiber predominance in muscle cramp and exertional myalgia.

In patients complaining of muscle cramps and exertional myalgia, we found a significant decrease of type 1 muscle fiber proportion in comparison with a control group. The possible mechanism of this change is discussed.

[Familial dementia of the Neumann type (subcortical gliosis)].

The case of a 70 year-old patient with familial dementia is reported. A cerebral biopsy and neurotransmitters dosages in CSF and brain tissue ruled out a primary dementia as Pick's or Alzheimer's disease. Our case may be related to Neumann's cases of subcortical gliosis.

Unclassified familial myopathy resembling Steinert disease, without myotonia.

A familial myopathy with predominantly proximal muscle atrophy is described. Although several clinical features such as sternomastoid and brachioradialis muscle involvement suggested Steinert disease, myotonia was not demonstrated by clinical examination or EMG. Histological data were consistent with myotonic dystrophy.
