OBJECTIVE Clinical involvement of the peripheral nervous system is uncommon in rheumatoid arthritis (RA); the most common disorders are multiple mononeuritis, sensorimotor neuropathy, and entrapment neuropathy. This study was undertaken to investigate the occurrence of electrophysiologically evident peripheral nerve involvement in RA patients without a(More)
Peripheral nerve conduction velocity and cortical evoked potentials were investigated in 48 patients with Friedreich's disease and in 35 relatives. There were 14 patients and 2 relatives who underwent sural nerve biopsy. In the patients sensory conduction velocity was moderately slowed, whereas sensory responses were markedly reduced. Nerve biopsy showed a(More)
In 19 median and 10 ulnar nerves of 28 healthy young volunteers, the maximum orthodromic sensory conduction velocity was studied along one or two fingers (the third and/or the fifth), the palm, and the forearm. In five 20 to 32-yr-old males and in a newborn male, post-mortem samples of either the median or the ulnar nerve were obtained from the finger(More)
A clinical and electrophysiological follow-up was carried out for 3 to 7 years on 15 patients with Friedreich's ataxia (FA). Sural nerve biopsy was performed once in all patients, and a second time 6-7 years later in three of them. Clinical worsening and progression of disturbance were evaluated according to IAP and IACR scales. Sensory orthodromic(More)
The bioptical morphometric and ultrastructural study of sural nerve in a 17-year-old boy with ataxia-telangiectasia (AT) is reported. Our findings include a loss of fibers, particularly of large ones, axonal degenerative changes, Schwann cell inclusions of various type, and rare signs of primary demyelination. Teased-fiber study showed paranodal myelin(More)
We studied orthodromic sensory conduction velocity along the distal and proximal segments of the median and ulnar nerves by tactile stimulation of the distal phalanx of the 3rd and 5th digits in 44 healthy subjects divided into 2 age groups: from 16 to 35 years and from 63 to 81 years. In the same nerves, we used selective electrical stimulation of the(More)
The effect of different cooking methods (natural convection, NC, forced convection, FC and forced convection/steam combined, FC/S) on selected physical properties of cooked pork Longissimus dorsi samples were compared. FC/S treatment was significantly faster (∼19 min) than NC and FC cooking treatments (∼27 min). The overall cook values at the center of all(More)
The authors present the case of a patient with concomitant pernicious anemia and positive antiglobulin test. After discussing previous cases in the literature and pointing out the probably simultaneous occurrence of the two, the authors comment on the persistence of a positive antiglobulin test after remission of the pernicious anemia and the association(More)
