Pre-diabetes and diabetes are a global epidemic, and the associated neuropathic complications create a substantial burden on both the afflicted patients and society as a whole. Given the enormity of the problem and the lack of effective therapies, there is a pressing need to understand the mechanisms underlying diabetic neuropathy (DN). In this review, we present the structural components of the peripheral nervous system that underlie its susceptibility to metabolic insults and then discuss the pathways that contribute to peripheral nerve injury in DN...

Objective: Foot and ankle exercise has been advocated as a preventative approach in reducing the risk of foot ulceration. However, knowledge about the appropriate types and intensity of exercise program for diabetic foot ulcer prevention is still limited. The current study aimed to examine the effects of an eight-week mini-trampoline exercise on improving foot mobility, plantar pressure and sensation of diabetic neuropathic feet. Methods: Twenty-one people with diabetic peripheral neuropathy who had impaired sensation perception were divided into two groups...

Spinal glial cell activation and cytokine secretion have been implicated in the etiology of neuropathic pain in a number of experimental models, including diabetic neuropathy. In this study, streptozotocin- (STZ-) induced diabetic rats were either untreated or treated with gabapentin (50 mg/kg/day by gavage for 2 weeks, from 6 weeks after STZ). At 8 weeks after STZ, hypersensitivity was confirmed in the untreated diabetic rats as a reduced response threshold to touch, whilst mechanical thresholds in gabapentin-treated diabetic rats were no different from controls...

Complications from diabetic foot ulcers often lead to increased patient morbidity. Much debate still ensues concerning surgical versus conservative management of neuropathic diabetic foot ulcerations. The present study assessed and compared the efficacy of metatarsal head resection and medical approach in the treatment of neuropathic diabetic foot ulcers located at the plantar surface of metatarsal heads. In a retrospective cohort study, 24 consecutive neuropathic diabetic foot ulcers in the lower area of the metatarsal heads that had undergone metatarsal head resection were included as the operative group...

BACKGROUND: In addition to inhibition of muscle and glandular hyperactivity, botulinum neurotoxin (BoNT) type A also interferes with pain processing. Previously, in a rat model of paclitaxel-induced polyneuropathy, abobotulinumtoxinA (aboBoNT-A) elicited analgesic effects not only in the injected paw, but also in the contralateral, non-injected paw. METHODS: Here, we assessed bilateral analgesic effects of unilateral aboBoNT-A in several chronic pain models in Sprague-Dawley rats...

The soluble epoxide hydrolase (sEH) is a regulatory enzyme responsible for the metabolism of bioactive lipid epoxides of both omega-6 and omega-3 long chain polyunsaturated fatty acids. These natural epoxides mediate cell signaling in several physiological functions including blocking inflammation, high blood pressure and both inflammatory and neuropathic pain. Inhibition of the sEH maintains the level of endogenous bioactive epoxy-fatty acids (EpFA) and allows them to exert their generally beneficial effects...

BACKGROUND: painDETECT (PD-Q) is a self-reported assessment of pain qualities developed as a screening tool for pain of neuropathic origin. Rasch analysis is a strategy for examining the measurement characteristics of a scale using a form of item response theory. We conducted a Rasch analysis to consider if the scoring and measurement properties of PD-Q would support its use as an outcome measure. METHODS: Rasch analysis was conducted on PD-Q scores drawn from a cross-sectional study of the burden and costs of NeP...

Our previous studies showed that direct injury to the sciatic nerve (chronic constriction injury or axotomy) is associated with a numerical increase in synaptic number in the rat spinal dorsal horn. The aim of this study was to determine whether painful diabetic neuropathy (PDN) was also associated with numerical changes in the synaptic or neuronal numbers in the spinal dorsal horn. Overall, 17 adult SD rats were allocated randomly into the control group (n=5) and the streptozotocin (STZ) group (n=12). STZ was injected intraperitoneally to induce diabetes...

Neuropathic pain is caused by a lesion or disease of the somatosensory system, including peripheral fibres (Aβ, Aδ and C fibres) and central neurons, and affects 7-10% of the general population. Multiple causes of neuropathic pain have been described and its incidence is likely to increase owing to the ageing global population, increased incidence of diabetes mellitus and improved survival from cancer after chemotherapy. Indeed, imbalances between excitatory and inhibitory somatosensory signalling, alterations in ion channels and variability in the way that pain messages are modulated in the central nervous system all have been implicated in neuropathic pain...

Neuropathic pain (NeuP) is a syndrome that results from damaged nerves and/or aberrant regeneration. Common etiologies of neuropathy include chronic illnesses and medication use. Chronic disorders, such as diabetes and alcoholism, can cause neuronal injury and consequently NeuP. Certain medications with antineoplastic effects also carry an exquisitely high risk for neuropathy. These culprits are a few of many that are fueling the NeuP epidemic, which currently affects 7%-10% of the population. It has been estimated that approximately 10% and 7% of US adults carry a diagnosis of diabetes and alcohol disorder, respectively...
