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...

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...

Hydrogen sulfide (H2S) is a crucial signaling molecule involved in several physiological and pathological processes. Nonetheless, the role of this gasotransmitter in the pathogenesis and treatment of neuropathic pain is controversial. The aim of the present study was to investigate the pain relieving profile of a series of slow releasing H2S donors (the natural allyl-isothiocyanate and the synthetics phenyl- and carboxyphenyl-isothiocyanate) in animal models of neuropathic pain induced by paclitaxel or oxaliplatin, anticancer drugs characterized by a dose-limiting neurotoxicity...

OBJECTIVE: Chronic pain is now recognized as a neural disease, which results from a maladaptive functional and structural transformation process occurring over time. In its chronic phase, pain is not just a symptom but also a disease entity. Therefore, pain must be properly addressed, as many patients still report unsatisfactory pain control despite on-going treatment. The selection of the therapy - taking into account the pathophysiological mechanisms of pain - and the right timing can result in a successful analgesic outcome...

The drugs that are currently available to treat neuropathic pain exhibit inadequate efficacy and numerous adverse effects. The present study compared the efficacy of combination therapy with pregabalin and morphine with that of each as a single agent in patients with neuropathic pain. The primary measurement was mean daily pain intensity. Secondary measurements included a pain questionnaire, adverse effects, mood and quality of life. Combination therapy of morphine plus pregabalin and morphine monotherapy were both more effective at reducing neuropathic pain than pregabalin monotherapy...

The clinical anti-cancer efficacy of vincristine is limited by the development of dose-dependent peripheral neuropathy. Up-regulation of transient receptor potential vanilloid 1 (TRPV1) is correlated with peripheral neuropathy following anti-cancer drug treatment. To analyze the contribution of TRPV1 to the development of vincristine-induced mechanical allodynia/hyperalgesia, TRPV1 expression in the rat dorsal root ganglion (DRG) was analyzed after vincristine treatment. Mechanical allodynia/hyperalgesia was tested with von Frey filaments 14 days after intraperitoneal administration of 0...

Light-operated drugs constitute a major target in drug discovery, since they may provide spatiotemporal resolution for the treatment of complex diseases (i.e. chronic pain). JF-NP-26 is an inactive photocaged derivative of the metabotropic glutamate type 5 (mGlu5) receptor negative allosteric modulator raseglurant. Violet light illumination of JF-NP-26 induces a photochemical reaction prompting the active-drug's release, which effectively controls mGlu5 receptor activity both in ectopic expressing systems and in striatal primary neurons...

OBJECTIVE: Neuropathic pain is difficult to manage and treat. Spinal cord stimulation (SCS) has become an established procedure for treating chronic neuropathic pain that is refractory to pharmacological therapy. In order to achieve better analgesia, a number of studies have evaluated the effectiveness of combining drug therapy with SCS. Cholecystokinin antagonists, such as proglumide, enhance the analgesic efficacy of endogenous opioids in animal models of pain. We previously reported that both systemic and spinal administration of proglumide enhances analgesia produced by both low- and high-frequency transcutaneous electrical nerve stimulation (TENS)...

Niclosamide is an oral antihelminthic drug used to treat parasitic infections in millions of people worldwide. However recent studies have indicated that niclosamide may have broad clinical applications for the treatment of diseases other than those caused by parasites. These diseases and symptoms may include cancer, bacterial and viral infection, metabolic diseases such as Type II diabetes, NASH and NAFLD, artery constriction, endometriosis, neuropathic pain, rheumatoid arthritis, sclerodermatous graft-versus-host disease, systemic sclerosis...

Harriet Daykin
Opioids remain the mainstay of analgesia for the treatment of moderate to severe acute pain. Even in the young, the use of opioids can be associated with an increased incidence of post-operative complications such as respiratory depression, vomiting, pruritus, excessive sedation, slowing of gastrointestinal function, and urinary retention. The need to manage acute pain in the older patient is becoming more common as the population ages, and increasingly older patients are undergoing more major surgery. Medical conditions are more common in older people and can result in the requirement of systemic analgesia for fractures, malignancy, nociceptive or neuropathic pain and peripheral vascular disease...

Background: Nucleoside reverse transcriptase inhibitors (NRTIs) are the cornerstone of the antiretroviral therapy for human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). However, their use is sometimes limited by the development of a painful sensory neuropathy, which does not respond well to drugs. Smoked cannabis has been reported in clinical trials to have efficacy in relieving painful HIV-associated sensory neuropathy. Objectives: The aim of this study was to evaluate whether the expression of endocannabinoid system molecules is altered during NRTI-induced painful neuropathy, and also whether endocannabinoids can attenuate NRTI-induced painful neuropathy...

AIM: Neuropathic pain responds poorly to drug treatments. Partial relief is achieved in only about half of the patients. Danggui Sini decoction (DSD), an aqueous extract of <i>Angelica sinensis, Ramulus Cinnamomi,</i> and <i>Radix Puerariae</i>, has been used extensively in China to treat inflammatory and ischemic diseases. The current study examined the putative effects of DSD on neuropathic pain. METHOD: We used two commonly-used animal models: chronic constriction injury (CCI) and diabetic neuropathy for the study...

Postoperative hyperalgesia (POH) is a condition characterized by signs and symptoms of pain despite the provision of conventional analgesia. In most cases, anesthesiologists are called upon soon after surgery, but occasionally it may occur as a late event. Persistent uncontrolled pain may transform into chronic or neuropathic pain. Correct diagnosis of POH is essential since similar phenomenon may exacerbate if misdiagnosed, while proper treatment is frequently achievable by pharmacological remedies. This review will describe the causes for POH and its bio-neuro-pharmacological basis, and clinical symptoms and signs directing the physician towards correct diagnosis of this paradoxical condition of pain, as well as modes capable of preventing POH from occurring...

Bacopa monnieri (BM, family Scrophulariaceae) is used in several traditional systems of medicine for the management of epilepsy, depression, neuropathic pain, sleep disorders and memory deficits. The present study investigated the potential of BM methanol (BM-MetFr) and BM n-butanol fractions (BM-ButFr) to reduce chemotherapy-induced emesis in Suncus murinus (house musk shrew). Cisplatin (30 mg/kg, i.p.) reliably induced retching and/or vomiting over a 2 day period. BM-MetFr (10-40 mg/kg, s.c.) and BM-ButFr (5-20 mg/kg, s...

Neuropathic pain resulting from peripheral neuronal damage is largely resistant to treatment with currently available analgesic drugs. Recently, ATP, lysophosphatidic acid, and platelet-activating factor (PAF) have been reported to play important inductive roles in neuropathic pain. In the present study, we found that pain-like behaviors resulting from partial sciatic nerve ligation (PSL) were largely attenuated by deficiency of lysophosphatidylcholine acyltransferase (LPCAT)2, which is one of the PAF biosynthetic enzymes...
