Objective This study was performed to determine the efficacy of selective peripheral nerve resection for treatment of persistent neuropathic pain after total knee arthroplasty (TKA). Methods Patients who underwent TKA in our department from January 2013 to July 2016 and experienced persistent pain around the knee joint after TKA were retrospectively included in the current study. Sixty patients were divided into experimental and control groups according the treatment they received. The treatment effect was evaluated by the Hospital for Special Surgery (HSS) knee score and visual analog scale (VAS) pain score preoperatively and at 1, 2, 3, 6, and 12 months postoperatively...

Here in, we report the preparation and evaluation of four 3-hydroxy-piperidine-N-benzyl-aryl-acylhydrazone derivatives (6a-d) for their potential antinociceptive activity. In the tail flick test, compounds 6a and 6d exhibited a significant increase in the latency time of the animals, in comparison to the control group. These two compounds also showed a significant increase in the nociceptive threshold from 1 to 6 h after treatment in the CCI neuropathic pain model. In both cases, the antinociceptive activity was blocked by naloxone, suggesting an opioid mechanism of action, but without sedative or motor coordination effects...

BACKGROUND: Neuropathic pain, and subsequent hypernociception, can be induced in mice by paclitaxel (PTX) administration and partial sciatic nerve ligation (PSNL). Its pharmacotherapy has been a clinical challenge, due to a lack of effective treatment. In two models of mouse neuropathic pain (PTX and PSNL) the antinociception induced by rosuvastatin and the participation of proinflammatory biomarkers, interleukin (IL)- 1β, TBARS and glutathione were evaluated. METHODS: A dose-response curve for rosuvastatin ip was obtained on cold plate, hot plate and Von Frey assays...

Several chemotherapeutic agents used for cancer treatment induce dose-limiting peripheral neuropathy that compromises patients' quality of life and limits cancer treatment. Recently, mitochondrial dysfunction has been shown to be involved in the mechanism of chemotherapy-induced peripheral neuropathy. SS-20 is a mitochondria-targeted peptide that promotes mitochondrial respiration and restores mitochondrial bioenergetics. In the present study, we examined the protective effect of SS-20 against the development of chemotherapy-induced peripheral neuropathy utilizing a murine model of peripheral neuropathy induced by oxaliplatin, a first-line chemotherapy agent for colon cancer...

OBJECTIVE: Develop and validate a low-intensity sinusoidal electrical stimulation paradigm to preferentially activate C-fibers in human skin. METHODS: Sinusoidal transcutaneous stimulation (4 Hz) was assessed psychophysically in healthy volunteers (n=14) and neuropathic pain patients (n=9). Pursuing laser Doppler imaging and single nociceptor recordings in vivo in humans (microneurography) and pigs confirmed the activation of "silent" C-nociceptors. Synchronized C-fiber compound action potentials were evoked in isolated human nerve fascicles in vitro...

Chronic Cough (CC) is common and often associated with significant comorbidity and decreased quality of life. In up to 50% of cases, the cough is refractory despite extensive investigation and treatment trials. It is likely that the key abnormality in refractory CC is dysfunctional, hypersensitive sensory nerves, similar to conditions such as laryngeal hypersensitivity and neuropathic pain. Areas covered: The aim of this systematic review is to assess drug therapies for refractory CC. The authors review the current management of CC and provide discussion of the similarities between neuropathic pain and refractory CC...

Pregabalin is a promising drug for the treatment of neuropathic pain, a chronic disease affecting a large population needing long-term treatment. However, due to its short half-life, the commercial tablet has to be administered 2 to 3 times per day, with inconvenience for patient and fluctuations of plasma concentration. In this study, a gastro-floating drug delivery system of pregabalin was developed to prolong the gastric retention of drugs absorbed or act in stomach or upper gastrointestinal tract. First of all, it was proved that the drug was mainly absorbed in stomach and upper gastrointestinal tract...

Objective: The dorsal horn P2Y13 receptor is involved in the development of pain behavior induced by peripheral nerve injury. It is unclear whether the expression of proinflammatory cytokines interleukin (IL)-1β and IL-6 at the spinal dorsal horn are influenced after the activation of P2Y13 receptor in rats with diabetic neuropathic pain (DNP). Methods: A rat model of type 1 DNP was induced by intraperitoneal injection of streptozotocin (STZ). We examined the expression of P2Y13 receptor, Iba-1, IL-1β, IL-6, JAK2, STAT3, pTyr1336 , and pTyr1472 NR2B in rat spinal dorsal horn...

Tapentadol is a novel pain reliever with apparently synergistic dual mechanisms of action, capable of addressing both nociceptive and neuropathic components of chronic pain. As an effective analgesic with good tolerability, tapentadol may be appropriate for patients suffering from severe chronic pain associated with low back pain (LBP) or osteoarthritis (OA). Efficacy studies of tapentadol in populations of patients with severe chronic LBP or OA pain suggest that tapentadol is non-inferior to oxycodone. Its tolerability, especially with respect to gastrointestinal (GI) side effects, may be better than that of other strong opioids in clinical trials and analyses of multiple trials...

Both N- and T-type calcium ion channels have been implicated in pain transmission and the N-type channel is a well-validated target for the treatment of neuropathic pain. An SAR investigation of a series of substituted aminobenzothiazoles identified a subset of five compounds with comparable activity to the positive control Z160 in a FLIPR-based intracellular calcium response assay measuring potency at both CaV 2.2 and CaV 3.2 channels. These compounds may form the basis for the development of drug leads and tool compounds for assessing in vivo effects of variable modulation of CaV 2...

Neuropathic pain is a severe health problem for which there is a lack of effective therapy. Ozone and Gardenia fruits have been used separately in pain relief for many years; however, their underlying mechanisms remain unclear. To investigate the pain‑relieving effects of combined ozone and Gardenia, a chronic constriction sciatic nerve injury (CCI) rat model was constructed and treated with ozone and gardenoside (Ozo&Gar), which is a compound found in Gardenia fruits. A total of 70 rats were randomly divided into five groups: Control (Ctrl), Ctrl + Ozo&Gar, Sham, CCI, and CCI + Ozo&Gar...

Treatment of neuropathic pain (NPP) continues to be a major challenge, and the underlying mechanisms remain to be elucidated. Previous studies have demonstrated that histone methylation is important in synaptic plasticity of the nervous system and may affect nuclear factor‑κB (NF‑κB) signaling through epigenetic mechanisms. The present study aimed to investigate the role of Jumonji C domain 6 (JMJD6), a histone demethylase, in a chronic constriction injury (CCI) model of NPP. On the third day post‑CCI surgery, a JMJD6 overexpressing lentiviral vector (LV‑JMJD6) was intrathecally injected in the rats...
