BACKGROUND Prevention of an intraneural injection of a local anesthetic during peripheral nerve blockade is considered important to avoid neurologic injury. However, the needle-nerve relationship during low-current electrical nerve localization is not well understood. METHODS We postulated that intraneural needletip location is common during low-current stimulation popliteal sciatic nerve blo...

Peripheral neuropathy is associated with chronic debilitating pain and difficult to treat. In this regard, the development of cell therapy neuropathic using adipose-derived mesenchymal stem cells (MSCs) seems be relevant. The work was devoted study impact allogeneic MSC transplantation on nociceptive reactions in response mechanical thermal stimuli gait parameters rats sciatic nerve injury. It ...

Dexamethasone is currently used for the treatment of peripheral nerve injury, but its mechanisms of action are not completely understood. Inflammation/immune response at the site of nerve lesion is known to be an essential trigger of the pathological changes that have a critical impact on nerve repair and regeneration. In this study, we observed the effects of various doses of dexamethasone on ...

purpose: to evaluate the effect of botulinum toxin-a as an alternate to surgery in acute complete sixth nerve palsy and to shorten the recovery period. methods: thirty patients with acute complete sixth nerve palsy received 1-10 units of botulinum toxin-a (dysport) injection in the medial rectus muscle within one month from the onset of palsy. toxin was injected directly into the muscle belly u...

Non-arteritic anterior ischemic optic neuropathy is caused by a transient optic nerve ischemia and results in permanent vision loss. Currently, there is no effective treatment for this ischemic optic nerve injury. This study characterized the duration and extent of ischemia induced after a coagulopathy injury to the optic nerve of adult rats. Acute ischemia was induced in adult rats by intraven...

Medialization thyroplasty or injection laryngoplasty for unilateral vocal fold paralysis cannot restore mobility of the vocal fold. Recent studies have shown that transplantation of mesenchymal stem cells is effective in the repair of nerve injuries. This study investigated whether adipose-derived stem cell transplantation could repair recurrent laryngeal nerve injury. Rat models of recurrent l...

Neuropathic pain remains a significant clinical problem. Current understanding implicates the spinal cord dorsal horn N-methyl-d-aspartate (NMDA) receptor apparatus in its pathogenesis. Previous reports have described NMDA antagonist reduction of nerve injury-induced thermal hyperalgesia and formalin injection-related electrical activity. We examined a panel of spinally administered NMDA antago...

We have previously reported that NADPH oxidase 2 (Nox2) is up-regulated in spinal cord microglia after spinal nerve injury, demonstrating that it is critical for microglia activation and subsequent pain hypersensitivity. However, the mechanisms and molecules involved in Nox2 induction have not been elucidated. Previous studies have shown that Toll-like receptors (TLRs) are involved in nerve inj...

background and aims . dentists administer thousands of local anesthetic injections every day. injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicit...
