There has been increasing interest in exploring the potential therapeutic benefit of the botulinum toxins in the management of neuropathic pain. Examples of neuropathic pain include painful diabetic polyneuropathy, postherpetic neuralgia (PHN), complex regional pain syndrome, trigeminal neuralgia and neuropathic low back pain. Other chronic pain syndromes may exhibit neuropathic features includ...

Reactive oxygen species (ROS) contribute to sensitization of pain pathways during neuropathic pain, but little is known about the primary sources of ROS production and how ROS mediate pain sensitization. Here, we show that the NADPH oxidase isoform Nox4, a major ROS source in somatic cells, is expressed in a subset of nonpeptidergic nociceptors and myelinated dorsal root ganglia neurons. Mice l...

Damage to peripheral nerves or the spinal cord is often accompanied by neuropathic pain, which is a complex, chronic pain state. Increasing evidence indicates that alterations in the expression and activity of gap junction channels in the spinal cord are involved in the development of neuropathic pain. Thus, this review briefly summarizes evidence that regulation of the expression, coupling, an...

BACKGROUND Neuropathic pain results from a nerve lesion or nerve damage. Because it is a subjective experience, patient-reported outcomes may measure both the symptoms and impact on the patient's life. The purpose of this study was to determine whether the Neuropathic Pain Symptom Inventory (NPSI) adequately assesses neuropathic pain symptoms in patients with diabetic peripheral neuropathy, pos...

BACKGROUND Long noncoding RNAs were involved in the processes of diabetes. Our study was aimed to explore clinical potential of LncRNA NONRATT021972 in diabetic neuropathic pain and investigate detailed mechanisms. METHODS 154 patients with type 2 diabetes were enrolled as experimental group paired with control. Patients without diabetes but neuropathy were enrolled to explore exclusive role ...

Damage to peripheral nerves following trauma or disease has a number of consequences including the emergence of neuropathic pain. Commonly, neuropathic pain sufferers experience spontaneous burning pain in and radiating from the area innervated by the damaged nerves, and an exquisite sensitivity to light touch stimuli, which are now perceived as painful. These neuropathic pains are often refrac...

OBJECTIVE The aim of this study was to evaluate validity and reliability of the Thai version of the Neuropathic Pain Symptom Inventory (NPSI-T) in Thai patients with neuropathic pain. Although the Thai version of Neuropathic Pain Symptom Inventory (NPSI-T) has been linguistically validated, the tool has to be psychometrically validated before applying to neuropathic pain patients in daily pract...

Patients with chronic neuropathic pain (non-CRPS) and brush-evoked allodynia watched a reflected image of their corresponding but opposite skin region being brushed in a mirror. Unlike complex regional pain syndrome Type 1, this process did not evoke any sensation at the affected area ('dysynchiria'). We conclude that central nociceptive sensitisation alone is not sufficient to cause dysynchiri...

introduction: peripheral nerve injury leads to neuropathic pain syndromes and different sensation like allodynia and hyperalgesia. different animal models of neuropathic pain are used to study the neuropathic pain mechanisms. the present study was performed on two models, (sni). the purpose of this study was comparing the behavioral responses of yhese two models and the role of saphenous and su...

A part of the immune system that improves (complements) the ability of antibodies and phagocytic cells to clear microorganisms and injured cells from an organism, attacks the pathogen's cell membrane, and encourages inflammation called complement system. It is main part of immune system. Over thirty proteins and protein pieces compose the complement system, including cell membrane receptors, an...
