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)
Dear Sir, Between February 1978 and December 1982 49 subjects, 24 males and 25 females, 6-59 years of age, suffering from fair to severe clinical signs of peripheral neuropathy, were examined in our Department of Clinical Neurophysiology. Based on family history and clinical findings, diagnosis was established in all but 7 (14 per cent) patients. 16(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)
A patient in whom an unusually severe Hodgkin's disease was complicated by subacute motor neuronopathy is described. This is a syndrome involving the lower motor neurons, recently described in patients with Hodgkin's disease and other lymphomas; its course is more often benign, and independent from that of the underlying lymphoma. In our patient it was(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)
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)
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)
The paper presents an experimental characterization of RFID technologies applied to process control in the marble industry. The final aim is the automatic detection of the presence of a marble slab under the abrasive or cutting heads inside an industrial machine. Four RFID systems at 125 kHz, 13.56 MHz, 868 MHz and 2.45 GHz have been implemented starting(More)
We compared the characteristics of near-nerve recorded sensory potentials elicited in response to electrical stimulation of digital nerves versus tactile stimulation of the digital skin in 17 healthy subjects with a mean age of 26 years. We also calculated the density of Meissner's corpuscles in the distal and proximal phalanx of digit III of 6 males who(More)
