The clinical, genetic and electrophysiological study of 3 patients with an association of a neuronal form of Charcot-Marie-Tooth Disease (CMTD) with a syndrome of continuous motor unit activity (CMUA) are reported, with light and electron microscopy of muscle and sural nerve biopsies in 2 patients. The unusual clinical features of CMTD were associated with(More)
OBJECTIVE To determine use of botanical dietary supplements (BDS) in women between the ages of 40 and 60 years at the University of Illinois at Chicago (UIC) clinics, including information about commonly used BDS, the reason for use, information resources used, and the overall perception of safety and efficacy of BDS. DESIGN Five hundred female(More)
A longitudinal study of 386 healthy Black and White women aged 35-60 years was conducted to determine the effects of physical activity and other related factors on lumbar bone mineral density over 24 months. Bone mineral density of the lumbar spine, L2-L4, was measured using dual energy x-ray (Hologic 1000). Physical activity levels in three dimensions(More)
The present paper is a histological, histochemical and electron microscopic study of biopsied specimens from both right and left Achilles tendon, sural nerve and gastrocnemius muscle in a case of peripheral neuropathy with decreased sensory conduction velocity within a cerebrotendinous xanthomatosis confirmed biochemically in a 29-year-old woman. The tendon(More)
A case of Marinesco-Sjögren syndrome, displaying the characteristic signs (ataxia, congenital cataract and mental retardation) is presented. Electrophysiological examination pointed to the presence of a sensorimotor peripheral neuropathy with an underlying mixed process of segmental demyelination and axonal degeneration (probably secondary). The sural nerve(More)
Tomaculous neuropathy represents the morphological substrate of the recurrent familial neuropathy with liability to pressure palsies. Some ultrastructural changes characterizing the tomaculous neuropathy can occur as incidental aspects in other different neuropathies. Few tomaculous neuropathy cases with clinical aspect of chronic polyneuropathy without(More)
Saliva of Triatoma infestans (Klug) produced a progressive reduction in the amplitude of the compound action potential recorded from rat sciatic nerve. The saliva also inhibited the Na+ current on GH3 cells. The data demonstrate that the saliva of T. infestans has an inhibitory effect on Na+ channels. We conclude that this effect may decrease the generation(More)
1. The effects of the saliva of the aquatic hemipteran Belostoma anurum were investigated on the isolated guinea-pig heart, perfused with Locke solution by the Langendorff's method. 2. The electrocardiogram (bipolar lead), the contractile force (g) and coronary flow (ml/min) were simultaneously recorded. 3. The total protein present in the saliva of each(More)
Clinical, electrophysiological and histological findings in four patients accidentally poisoned with the organophosphorus insecticide Dipterex are reported. Three to five weeks after insecticide ingestion signs of a distal sensorimotor (preponderantly motor) neuropathy occurred. The patients complained of paraesthesia in the lower limbs, and two of them of(More)
