Asterixis was observed in 20 cases of focal brain lesions. Metabolic or toxic factors were excluded. An electromyogram study of asterixis was carried out in nine cases to establish the diagnosis. The site of the focal lesion was either parietal or mesencephalic and was always contralateral to the asterixis. "Focal asterixis" could result from a dysfunction(More)
BACKGROUND AND DESIGN We retrospectively studied 12 patients with dermatomyositis (DM) with at least one laboratory criterion of muscle involvement but without muscle weakness. We reported their outcome without systemic corticosteroid treatment and searched for distinctive baseline data and associated neoplasia among a group of 29 patients with classic DM.(More)
BACKGROUND AND DESIGN Thalidomide therapy was shown to be effective in numerous dermatologic diseases. As reliable methods of contraception are now available, neurotoxicity has become the most important side effect limiting the use of thalidomide. The incidence of this neuropathy and its relationship to thalidomide doses are still matters of debate. In a(More)
OBJECTIVES To assess by electrophysiology the effect of tibial selective neurotomy on muscle imbalance of the spastic ankle. METHOD The amplitudes of the H reflexes, M responses (muscle contractions recorded after stimulation of the tibial nerve), and Hmax:Mmax ratio were recorded in 12 patients with chronic lower limb spasticity, before and one month(More)
A methodology which accounts for uncertainty or imprecision in experimental observations and both norm and pathology definitions is developed on the basis of a distance measure between fuzzy numbers. These fuzzy numbers may represent, respectively, the measurements, norm, and pathology. The distance measure, called normalized fuzzy pathology index (NFPI),(More)
A young woman suffering from sleeping sickness was treated with melarsoprol. Thirty-eight days after the first administration of this organo-arsenic compound, myalgias, distal paresthesias and rapidly progressive weakness developed in all four limbs. Electrophysiological studies were misleading for Guillain-Barré syndrome. Neuropathological data included(More)
