Neuronal nitric oxide synthase (nNOS) is a key enzyme for nitric oxide production in neuronal tissues and contributes to the spinal central sensitization in inflammatory pain. However, the role of nNOS in neuropathic pain remains unclear. The present study combined a genetic strategy with a pharmacologic approach to examine the effects of genetic knockout and pharmacologic inhibition of nNOS on...
BACKGROUND We have previously reported that nerve injury-induced neuropathic pain is attenuated in toll-like receptor 2 (TLR2) knock-out mice. In these mice, inflammatory gene expression and spinal cord microglia actvation is compromised, whereas the effects in the dorsal root ganglia (DRG) have not been tested. In this study, we investigated the role of TLR2 in inflammatory responses in the DR...
Head injury is a common occurrence in motor vehicle accidents. There are numerous causes for cranial nerve injury that include head trauma or other lesions. Few studies regarding cranial nerve injury following mild head trauma (GCS: 14 - 15) exist in the literature. The oculomotor nerve is a somatic and visceral motor nerve. When it is completely injured the result is ptosis, pupils that are no...
BACKGROUND Abdominoplasty is a common cosmetic procedure; nerve injury is an underexplored risk of the procedure. OBJECTIVE The authors review existing literature to examine the incidence and treatment of nerve injuries after abdominoplasty procedures and provide a treatment algorithm based on their results. METHODS A search of the literature on MEDLINE, EMBASE, and the Cochrane Database of...
Introduction: Glycogen Synthase Kinase-3β (GSK-3β) participates in several signaling pathways and plays a crucial role in neurodegenerative diseases, inflammation, and neuropathic pain. The ratio of phosphorylated GSK-3β over total GSK-3β (p-GSK-3β/t-GSK-3β) is reduced following nerve injury. Apoptosis is a hallmark of many neuronal dysfunctions in the context of neuropathic pain. Thus, this st...
Peroneal nerve compromise results in the clinical complaint of weakness of the ankle dorsiflexors and evertors. This peripheral origin of foot drop has been reported due to numerous traumatic and insidious causes. Traumatic causes of nerve injury occur in association with musculoskeletal injury or with isolated nerve traction, compression, or laceration. Insidious causes include mass lesions an...
Objective (s): Scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. Several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. This study evaluates the translational capacity of four of physical injury models to induce scar formation aro...
BACKGROUND Peripheral nerve injuries that provoke neuropathic pain are associated with chronic inflammation and nervous lesions. The authors hypothesized that chronic neuropathic pain might be caused by chronic inflammation resulting from a nervous autoimmune reaction triggered by nerve injury. METHODS The authors observed chronic inflammation and neuropathic behaviors for up to 12 weeks afte...
Nerve injury induces a state of prolonged thermal and mechanical hypersensitivity in the innervated area, causing distress in affected individuals. Nerve injury-induced hypersensitivity is partially due to increased activity and thereby sustained release of neurotransmitters from the injured fibers. Glutamate, a prominent neurotransmitter in primary afferents, plays a major role in development ...
Background. Nerve stimulation can facilitate correct needle placement in peripheral regional anesthesia. The aim of this study was to determine whether the high threshold current is associated with reduced nerve injury due to fewer needle-nerve contacts compared with low current. Methods. In anaesthetized pigs, thirty-two nerves of the brachial plexus underwent needle placement at low (0.2 mA) ...
