Regional brain glucose metabolism has been studied in a case of mitochondrial encephalomyopathy with ragged red fibers, using positron emission tomography with fluorodeoxyglucose as the tracer. A marked decrease in glucose utilization was found in all gray structures, with a preponderance of metabolic alterations in posterior cortical regions and thalamus… (More)
Otitis media in a 43 year-old male patient was followed by signs of chronic meningitis with persistent headaches, moderate pleiomorphic lymphocytosis of CSF without hypoglycorrhachia and unilateral impairment of cranial nerves XI to II. These signs were accompanied by widespread inflammation with general deterioration of the patient's condition. After a… (More)
We studied ten cases of disseminated sensory neuropathy. Both sexes were similarly involved. Except in one case, the first symptoms appeared between ages 20 and 50.

The first evidence of disease consisted in pains in the lower limbs, probably caused by inflammatory processes involving the fascia. Biochemical, radiological and histological examinations allowed the diagnosis to be made.
The authors discuss internuclear ophthalmoplegia associated with non-paralytic pontine exotropia of the contralateral eye. Impairment of the posterior oculogyric tract in its protuberantial segment, resulting in oculographic signs of alteration in the contralateral continuation. Seems to be responsible for the exotropia.
