Single - fiber EMG in Meniere ' s Disease
نویسندگان
چکیده
Objective: To assess neuromuscular transmission (NMT) in patients with Meniere's disease (MD), in which the precise etiology is unknown and a channelopathy hypothesis has been proposed Methods: Single fiber electromyography (SFEMG) during voluntary contraction of the extansor digitorum communis muscle, nerve conduction studies of upper and lower extremities and concentric needle electromyography of the extensor digitorum communis were performed on 20 patients (13 female, 7 male) with MD and 12 age-matched normal controls (4 female, 8 male). Mean jitter value was calculated for each subject and was compared with the values recorded from normal controls. Results: The mean jitter values of the MD group were not different from the mean jitter values of normal control subjects. Conclusion: Even though our findings are not consistent with neuromuscular conduction defect, this doesn’t exclude presence of channelopathy in the pathogenesis of MD.

Meniere’s syndrome is the most common cause of true vertigo that in 75-90% of the cases can be acceptably controlled by various methods of medical treatment. But in this case in spite of 13 years medical therapy, recurrent attacks of vertigo continue to occur and the patient completely become disable. During the last month, six severe vertigo attacks recorded by patients before surgery....

Background: Meniere’s disease (MD) is a chronic illness defined as an idiopathic syndrome of endolymphatic hydrops. Benign paroxysmal positional vertigo (BPPV) is a balance disorder and can be the sequel of diverse inner ear impairments. Objectives: The purpose of this study was to investigate the prevalence of BPPV in MD patients. Materials and Methods: All patients with definite or prob...

In this article, a novel structure of photonic crystal fiber with nearly zero ultra-flattened chromatic dispersion and ultra-low confinement loss is presented. By replacing the circular air-holes of two first rings with the elliptical air-holes, a fiber with outstanding features of chromatic dispersion and confinement loss is designed. The proposed structure is optimized for operating in a wide...
