Traumatic neuropathic pain caused by traumatic neuroma has long been bothering both doctors and patients, the mechanisms of traumatic neuropathic pain are widely discussed by researchers and the treatment is challenging. Clinical treatment of painful neuroma is unclear. Numerous treatment modalities have been introduced by experts in this field. However, there is still no single standard recognized treatment.Different forms of treatments have been tested in animals and humans, but pharmacotherapies (antidepressants, antiepileptics) remain the basis of traumatic neuropathic pain management...

BACKGROUND: There is a need for better joint pain treatment, but development of new medication has not been successful. Pre-clinical models with readouts that better reflect the clinical situation are needed. In patients with joint pain, pain at rest and pain at walking are two major complaints. NEW METHOD: We describe a new way of calculating results from gait analysis using the CatWalk™ setup. Rats with monoarthritis induced by injection of Complete Freund's Adjuvant (CFA) intra-articularly into the ankle joint of one hind limb were used to assess gait and dynamic weight bearing...

BACKGROUND: Cellular responses to nerve injury play a central role in the pathogenesis of neuropathic pain. However, the analysis of site specific cellular responses to nerve injury and neuropathic pain is limited to immunohistochemistry staining with numerous limitations. NEW METHODS: We proposed to apply flow cytometry to overcome some of the limitations and developed two protocols for isolation of cells from small specimens of the sciatic nerve and dorsal root ganglion (DRG) in mice...

Therapeutic interventions after spinal cord injury (SCI) routinely are designed to address multiple aspects of the primary and/or secondary damage that occurs. Exercise has a demonstrated efficacy for post-SCI complications such as cardiovascular dysfunction, neuropathic pain and chronic inflammation yet there is little understanding of the mechanisms by which improvements might result from this non-invasive approach. Here we review several of our observations of molecular and cellular changes within the injured spinal cord following acute or delayed exercise regimens that illustrate the potential for positive effects on neuroprotection and rehabilitation...

Mechanical hypersensitivity is a debilitating symptom for millions of chronic pain patients. It exists in distinct forms, including brush-evoked dynamic and filament-evoked punctate hypersensitivities. We reduced dynamic mechanical hypersensitivity induced by nerve injury or inflammation in mice by ablating a group of adult spinal neurons defined by developmental co-expression of VGLUT3 and Lbx1 (VT3(Lbx1) neurons): the mice lost brush-evoked nocifensive responses and conditional place aversion. Electrophysiological recordings show that VT3(Lbx1) neurons form morphine-resistant polysynaptic pathways relaying inputs from low-threshold Aβ mechanoreceptors to lamina I output neurons...

The McGill Pain Questionnaire (MPQ) is composed of 78 words reflecting the mechanisms underlying chronic pain conditions. Ischemic ulcer pain is generally regarded as a nociceptive and inflammatory pain condition. However, it is sometimes refractory to nonsteroidal anti-inflammatory drug (NSAID) and opioid treatment. We categorized ischemic pain into nociceptive/inflammatory pain (NocP) or neuropathic pain (NeP), on the basis of patients' descriptions of their pain using the MPQ. We investigated pain characteristics of 365 patients with NeP and 124 with NocP using the 78 words of the MPQ...

BACKGROUND AND OBJECTIVE: The treatment of neuropathic pain due to low-back (lumbosacral) radiculopathies, a common source of neuropathic pain, is challenging and often requires a multimodal therapeutic approach. The capsaicin 8% patch is the first topical analgesic licensed for peripheral neuropathic pain. To evaluate this treatment, a subset of patients with painful radiculopathy (lumbar and cervical, including ventral and dorsal rami) enrolled into the multicenter, non-interventional QUEPP study (Qutenza™ - safety and effectiveness in peripheral neuropathic pain) was analyzed...

PURPOSE OF REVIEW: Our goal is to examine the processes-both central and peripheral-that underlie the development of peripherally-induced neuropathic pain (pNP) and to highlight recent evidence for mechanisms contributing to its maintenance. While many pNP conditions are initiated by damage to the peripheral nervous system (PNS), their persistence appears to rely on maladaptive processes within the central nervous system (CNS). The potential existence of an autonomous pain-generating mechanism in the CNS creates significant implications for the development of new neuropathic pain treatments; thus, work towards its resolution is crucial...

Vaso-occlusive crises are the most common manifestation of sickle cell disease (SCD) and the main cause of hospital admission in these patients. There is emerging evidence that vaso-occlusive pain has both nociceptive and neuropathic components. However, the treatment of SCD-related pain with neuropathic drugs has not yet been systematically studied, particularly in children. We describe a 14-year-old girl with SCD and multiple hospital admissions for pain management for severe acute vaso-occlusive pain episodes...
