Neuropathic pain arises from injury to the nervous system. Conditions associated with neuropathic pain are diverse, and lesions and/or pathological changes in the central nervous system (CNS) or peripheral nervous system (PNS) can frequently, but not always, be identified. It is difficult to treat, with patients often on multiple, different classes of medications, all with appreciable adverse side effect profiles. Consequently, there is a pressing need for the development of new medications. The development of such therapeutics is predicated on a clear understanding of the relevant molecular and cellular processes that contribute to the development, and maintenance, of the neuropathic pain state...

Peripheral neuropathies (PNs) are injuries or diseases of the nerves which arise from varied aetiology, including metabolic disease, trauma and drug toxicity. The clinical presentation depends on the type of neuropathy, and may include the loss of motor, sensory and autonomic functions, or development of debilitating neuropathic pain distal to the injury site. It can be challenging to identify the aetiology of PNs, as the clinical syndromes are often indistinct. However, the mechanisms that underlie pathological changes in peripheral neuropathy are fundamentally different, depending on the trigger...

Pain is a complex sensation that may be protective or cause undue suffering and loss of function, depending on the circumstances. Peripheral nociceptor neurons (PNs) innervate most tissues, and express ion channels, nocisensors, which depolarize the cell in response to intense stimuli and numerous substances. Inflamed tissues manifest inflammatory hyperalgesia in which the threshold for pain and the response to painful stimuli are decreased and increased, respectively. Constituents of the inflammatory milieu sensitize PNs, thereby contributing to hyperalgesia...

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder affecting about 1 in 3,500 individuals. Chronic pain is commonly reported among individuals with NF1 and plexiform neurofibroma tumors (PNs). Acceptance and Commitment Therapy (ACT), an empirically supported method for addressing chronic pain, helps individuals re-focus on valued relationships and activities. This pilot study investigated the feasibility and preliminary efficacy of a brief ACT workshop in the NF1 population. Eligible participants included adolescents and young adults (AYA; 12-21 years) with NF1 and chronic pain that interfered with daily functioning and their parents...

Brachial plexopathy usually results from an iatrogenic brachial plexus injury and can sometimes cause severe chronic pain and disability. There are a number of possible treatments for this condition, including medication, physical therapy, nerve blocks, and neuromodulation, but they are not always successful. Recently, combined spinal cord stimulation (SCS) and peripheral nerve stimulation (PNS) have been tried for various chronic pain diseases because of their different mechanisms of action.Here, we describe the case of a 54-year-old man who was diagnosed with brachial plexopathy 8 years ago...

Neuronal hyperexcitability in the anterior cingulate cortex (ACC) is considered as one of the most important pathological changes responsible for the chronification of neuropathic pain. However, the underlying mechanisms remain elusive. In the present study, we investigated the possible mechanisms using a rat model of chronic constriction injury (CCI) to the sciatic nerve. We found a substantial decrease in hyperpolarization-activated/cyclic nucleotide-gated (HCN) currents in layer 5 pyramidal neurons (L5 PNs) in ACC slices, which dramatically increased the excitability of these neurons...
