Entrapment of the ulnar nerve at the elbow is the second most common focal peripheral neuropathy. Recent advances have facilitated the electrodiagnosis of this common nerve entrapment. The goals of electrodiagnosis are to localize ulnar nerve dysfunction, confirm that the disturbance is confined to the ulnar nerve, and assess the severity of ulnar nerve dysfunction. The goal of this review is t...

Clinically, lidocaine requires a larger concentration than bupivacaine to block nerves. Bupivacaine has a higher lipid solubility, tissue permeability, and affinity for sodium channels than lidocaine, resulting in greater anesthetic potency. Local anesthetics require access to the sodium channel from the intracellular milieu. In this study, we sought to determine the intracellular concentration...

Bupivacaine-induced regeneration was studied in the rat soleus muscle in the presence or absence of innervation, in the presence of tetrodotoxin (TTX)-induced block of nerve impulse conduction, and/or in the presence of vinblastine-induced block of nerve axoplasmic flow. Part of experiments were carried out on tenotomized muscles. Regenerated muscles were analysed for myosin heavy chain (MHC) c...

conclusions open gastrostomy was successfully performed under subcostal tap block with small dose fentanyl supplementation. the subcostal tap block is considered a useful anesthetic choice in surgery for high risk patients. introduction many papers have reported that tap block provides effective postoperative analgesia, but the sole use of tap block for surgical anesthesia has been rarely repor...

Twenty four patients with pure motor neuropathy are reported. The chronic motor involvement associated with fasciculations and cramps, mainly in the arms, led, in most patients, to an initial diagnosis of motor neuron disease. In some patients (nine of 24), there was no appreciable muscle atrophy. Tendon reflexes were often absent or weak. The finding of persistent multifocal conduction block c...

Carotid body chemoreceptors transduce a decrease in arterial oxygen tension into increased action potential (AP) activity on the sinus nerve, which increases the drive to breathe. The mechanism by which AP activity increases is unresolved, but acetylcholine (ACh), acting through nicotinic receptors, is postulated to be a major contributor to nerve excitation based partly on the demonstration th...

Although it is a well-established fact that dietary fish oil can improve nerve conduction velocity in diabetic rat, but the exact mechanism of its action is unknown. Therefore, in this study we measured the blood glucose level of all animals for evaluating the possible effect of fish oil in improvement of nerve conduction velocity in diabetic neuropathy via regulation of blood glucose level. Fo...
