Peripheral nerve injuries and diseases often lead to pain persisting beyond the resolution of damage, indicating an active disease-promoting process, which may result in chronic pain. This is regarded as a maladaptive mechanism resulting from neuroinflammation that originally serves to promote regeneration and healing. Knowledge on these physiological and pathophysiological processes has accumulated over the last few decades and has started to yield potential therapeutic targets. Key players are macrophages, T-lymphocytes, cytokines, and chemokines...

Neuropathic pain represents a highly unmet medical need because most of the available treatments have a modest efficacy or dose-limiting side effects. Hence, novel therapeutic perspectives are warranted. Many compounds acting on new pain targets are in preclinical or early clinical development. Only few clinical trials have suggested their clinical relevance in neuropathic pain. This concerns in particular NaV1.7 antagonists and angiotensin type II inhibitors. Another type of emerging drug therapy in neuropathic pain is represented by drugs largely used for other indications, such as botulinum toxin A and the antiepileptic oxcarbazepine, which have recently found to be effective in peripheral neuropathic pain...

Patients with the same neuropathic pain disorder may have completely different sensory signs and symptoms yet receive the same medicinal treatment. New concepts suggest that patient stratification according to their pain mechanisms, reflected in their sensory phenotype, could be promising to implement an individualized therapy in neuropathic pain. Retrospective classification of patients according to their sensory phenotype showed predictive validity and reliability for treatment response in certain subgroups of patients...

A strong link between histone deacetylases (HDACs) and nociceptive hypersensitivity has been indicated in different pain models. However, the underlying molecular and cellular mechanisms remain elusive. Here, we discovered that partial sciatic nerve ligation-induced mechanical allodynia and thermal hyperalgesia in mice were associated with increased mRNA and protein expressions of HDAC5 (a member of class IIa HDACs) and SRY-related HMG-box 10 (SOX10) in the ipsilateral lumbar dorsal horn. Gene knockdown of spinal HDAC5 or SOX10 attenuated partial sciatic nerve ligation-induced nociceptive hypersensitivity, companied with decrease of spinal neuronal sensitization markers, namely phosphorylated-Erk, phosphorylated-GluN1 (ser896), and c-Fos...

Background: Spinal cord stimulation (SCS) is a proven and effective treatment for neuropathic pain conditions such as failed back surgery syndrome (FBSS). The hypothesis that different settings for SCS parameters activate unique, pain-relieving mechanisms has boosted the development of various SCS paradigms. High density spinal cord stimulation (HD-SCS) is one of those promising, novel stimulation forms characterized by subthreshold stimulation, delivering more pulses per second and a higher pulse density to the spinal cord than conventional SCS...

Neuropathic pain is a worldwide health problem with no consensus regarding its optimal therapy. This study compared the analgesic effect and gastric, hepatic, and renal safety of combined low doses of diclofenac and celecoxib with gabapentin versus their individual high doses in the treatment of neuropathic pain in rats. Left sciatic nerve ligation was used as neuropathic pain model. Rats were allocated into 7 groups (7 rats for each): sham control; model group (received vehicle); Gaba-group (received gabapentin (100 mg/kg /day); Diclo 10-group (received diclofenac (10 mg/kg); Cele 10-group (received celecoxib (10 mg/kg/day); Gaba + Diclo 5 (receivedgabapentin(100 mg/kg /day) plus diclofenac (5 mg/kg); Gaba + Cele 5 (received gabapentin (100 mg/kg/day) plus celecoxib (5 mg/kg))...

PURPOSE OF REVIEW: Osteoarthritis is one of the most frequent causes of chronic pain. Because there is no causal treatment of osteoarthritis, sufficient pain control is of uppermost importance but often not met. The review reports recent advances and controversies in our understanding of osteoarthritis pain and its treatment. RECENT FINDINGS: Osteoarthritis pain is determined by processes at different levels. An important local factor of pain generation in the joint is inflammation such as synovitis, and neuropathic components of osteoarthritis pain are being discussed...

The present study aimed to determine whether isoflurane interferes with the analgesic effects of acupuncture (Ac) and electroacupuncture (EA), using a neuropathic pain (NP) rat model. In total, 140 male Wistar rats were used; isoflurane-induced nociceptive response was evaluated using the von Frey test, serum calcium-binding protein β (S100β) levels, and nerve growth factor (NGF) levels in the left sciatic nerve. The NP model was induced by chronic constriction injury (CCI) of the sciatic nerve at 14 days after surgery...

The study of α4β2 nicotinic receptors has provided new indications in the treatment of pain. Efforts have been made to explore new α4β2 nicotinic receptor agonists, including TC-2559, as antinociceptive drugs. In this study, we discovered a set of novel epibatidine analogs with strong binding affinities to the α4β2 nicotinic receptors. Among these compounds, C-159, C-163, and C-9515 attenuated formalin-induced nociceptive responses in mice; C-9515 caused the most potent analgesic effect, which was blocked by mecamylamine, a non-selective nicotinic receptor antagonist...

We describe the mixed-methods (qualitative and quantitative) development and preliminary validation of the Patient Assessment for Low Back Pain - Symptoms (PAL-S), a patient-reported outcome measure for use in chronic low back pain (cLBP) clinical trials. Qualitative methods (concept elicitation, cognitive interviews) were used to identify and refine symptom concepts and quantitative methods (Classical test theory, Rasch measurement theory) were used to evaluate item- and scale-level performance of the measure using an iterative approach...

OBJECTIVE(S): Neuropathic pain due to lesion or dysfunction of the peripheral or central nervous system is often refractory to the conventional analgesics. Currently, there is no proven treatment to prevent or cure neuropathic pain. A recent surge of new data suggests the potential effects of vitamin D in the medical community. This study was designed to determine whether acute or chronic vitamin D administration was effective in alleviating symptoms of neuropathic pain in a rat model of neuropathic pain...

Introduction: Animal experimental evidence suggests that mechanisms of pain generation and response to treatment differ between neuropathic pain in the cephalic and the extracephalic innervation territories. Objectives: The objective of the study was to examine whether in humans an identical peripheral painful neuropathy is associated with different pain qualities and sensory abnormalities in the face as compared with the thoracic region. Methods: We retrospectively analysed epidemiological and clinical data of 639 patients with postherpetic neuralgia (PHN) in the face and at the trunk who were collected within a cross-sectional cohort survey and compared the respective sensory symptom profiles captured with the painDETECT questionnaire...

Dry eye is one of the most common ocular problems in ophthalmology clinic. With the change of social environment and people's life style, the prevalence of dry eye disease is increasing. Currently, the diagnosis criteria for dry eye is controversial, diagnosis of dry eye mainly rely on the comprehensive assessment of symptoms and the presence of associated ocular surface signs. However, previous studies have shown a poor correlation between dry eye symptoms and objective clinical signs in patients. Recent studies have found that neuropathic pain plays an important role in the occurrence of discordance between symptoms and signs in dry eye disease...

Diabetic neuropathic pain (DNP) is one of the common complications of diabetes. Depression (DP) is also one of the common complications of diabetes. P2X7 receptors play an important role in the transmission of nociceptive signal and are associated with depressive illness. In the study, the hyperalgesia, allodynia and depressive behaviours of rats with comorbidity of DNP and DP were confirmed by the thermal withdrawal latency (TWL) test, mechanical withdrawal threshold (MWT) test, sucrose preference test (SPT), immobility time of forced swimming test (IMFST) and open-field test (OFT)...

PURPOSE OF REVIEW: This article aims to review select applications of Transcranial Magnetic Stimulation (TMS) that have significant relevance in geriatric psychiatry. RECENT FINDINGS: Small study sizes and parameter variability limit the generalizability of many TMS studies in geriatric patients. Additionally, geriatric patients have unique characteristics that can moderate the efficacy of TMS. Nonetheless, several promising experimental applications in addition to the FDA-approved indication for major depression have emerged...
