Touch MEdical MEdia 53 Fasciculation, which is observed in various peripheral motor neuron disorders, is most frequently found in nonprogressive benign fasciculation syndrome (BFS). Patients with BFS never exhibit muscle atrophy or pathologic weakness and not all such patients visit hospitals; therefore, the prevalence and characteristics of BFS still need to be established. However, among the ...

The aim of this study was to determine first, if benign fasciculations and those in amyotrophic lateral sclerosis can de distinguished on the basis of their waveforms or firing characteristics, and second to determine how fasciculation parameters evolved with progression of amyotrophic lateral sclerosis. Fasciculation potentials recorded from 63 muscles of 28 patients with definite amyotrophic ...

Fascikulace jsou jedním z nepříliš častých, ale potenciálně závažných neurologických symptomů a mohou se vyskytnout u celé řady i jiných nemocí nebo stavů. Mohou vznikat mnoha různých příčin, od metabolickoendokrinních (porucha metabolismu vápníku, hořčíku, hyperthyreóza), přes nežádoucí účinek farmak (succinylcholin, depolarizující myorelaxans, inhibitory ...

Peripheral axons from auditory spiral ganglion neurons (SGNs) form an elaborate series of radially and spirally oriented projections that interpret complex aspects of the auditory environment. However, the developmental processes that shape these axon tracts are largely unknown. Radial bundles are comprised of dense SGN fascicles that project through otic mesenchyme to form synapses within the ...

To the Editor:—Schreiber et al. noted an association between larger doses of succinylcholine and a reduced incidence of fasciculation and myalgia. However, pretreatment with a nondepolarizing neuromuscular blocker is also associated with a reduced risk of fasciculation and myalgia. It is a common practice for clinicians to use a larger dose of succinylcholine when they have provided pretreatmen...

Upon inducting general anesthesia in the operating room, we have observed a prompt increase in the bispectral index (BIS) after the intravenous injection of suxamethonium. We hypothesized that the cause of this BIS increase is muscle hyperactivity owing to fasciculation. However, no reports have been published regarding this abrupt increase in the BIS upon the induction of general anesthesia by...

BACKGROUND Succinylcholine is a popular muscle relaxant and one of its most common side effects is muscle fasciculation. The purpose of this study was to evaluate the efficacy of remifentanil in preventing succinylcholine-induced fasciculation in patients undergoing general anesthesia. METHODS In aprospective, double blind study, 60 ASA I & II patients were randomly assigned into two groups (...
