Because of high prevalence of upper limbs pain and carpal tunnel sndrome and the need of proofing of diagnosis by nerve conduction study (NCS) testing of edian nerve is one of the most common exams in electro-diagnostic centers. In interpretation of findings of nerve conduction study presence of a normal range for findings is one of the most important points.Materials and Methods: In this study...
We report a case of a patient, chronically treated with oral lithium, who presented with an extremely prolonged (42-hour) duration of sensory and motor paralysis following an uneventful infraclavicular block for hand surgery that was performed under ultrasound guidance using bupivacaine and lidocaine. Due to its direct effect on nerve conduction of action potential, we propose that lithium may ...
Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelinating disease of the central nervous system (CNS) and can be induced by inoculation of animals with homogenized CNS tissue or highly purified myelin proteins such as myelin basic protein (MBP) or proteolipid protein (PLP). It is widely studied as a possible animal model of multiple sclerosis. We performed the present neu...
BACKGROUND The neuropathy of type II diabetes mellitus (DM) is increasing in prevalence worldwide. We aimed to test the hypothesis that in a rodent model of type II DM, neuropathy would lead to increased neurotoxicity and block duration after lidocaine-induced sciatic nerve block when compared with control animals. METHODS Experiments were carried out in Zucker diabetic fatty rats aged 10 wee...
The effect of direct current on the propagated compound action potential in a cutaneous branch of the radial nerve of the dog was studied and a convenient method for applying electrical current to a nerve is described. Changes in the flow of blocking current, even when these were made slowly during a period of 5-10 sec, caused stimulation of the nerve. The method was satisfactory for producing ...
Purpose: There are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. Axonal regeneration is relation to various factors. In this investigation we decided to evaluate the effects of nerve regeneration age-dependent on injured rat sciatic nerv. Materials and Methods: For this study, the right sciatic nerve of...
ABSTRACT The object of this study is determination of normative values of nerve conduction studies (NCS) among the population of Guilan Province. We selected 216 at the ages of 20-59yr on the basis of their medical histories and examination , and on condition that they had no factors or diseases interfering with nerve conduction by convenience sampling method. In this cross-sectional study, t...
We report a patient with primary ulnar entrapment neuropathy in the midarm. Stimulation of multiple sites along the ulnar nerve showed a motor conduction block at a distance of 7.5-10 cm proximal to the medial epicondyle, where the nerve was compressed by the medial intermuscular septum. Anatomically, the possibility of ulnar nerve entrapment in this segment has long been suggested, and stimula...
