ReviewDiagnosis and management of neuropathic pain: review of literature and recommendations of the Polish Association for the Study of Pain and the Polish Neurological Society - Part Two.
Neuropathic pain may be caused by a variety of lesions or diseases of both the peripheral and central nervous system. The most common and best known syndromes of peripheral neuropathic pain are painful diabetic neuropathy, trigeminal and post-herpetic neuralgia, persistent post-operative and post-traumatic pain, complex regional pain syndrome, cancer-related neuropathic pain, HIV-related neuropathic pain and pain after amputation. ⋯ A multidisciplinary team of Polish experts, commissioned by the Polish Association for the Study of Pain and the Polish Neurological Society, has reviewed the literature on various types of neuropathic pain, with special focus on the available international guidelines, and has formulated recommendations on their diagnosis and treatment, in accordance with the principles of evidence-based medicine (EBM). High quality studies on the efficacy of various medicines and medical procedures in many neuropathic pain syndromes are scarce, which makes the recommendations less robust.

Randomized Controlled TrialA double-blind, placebo-controlled, crossover pilot trial with extension using an oral mucosal cannabinoid extract for treatment of chemotherapy-induced neuropathic pain.
Neuropathic pain caused by chemotherapy limits dosing and duration of potentially life-saving anti-cancer treatment and impairs quality of life. Chemotherapeutic neuropathy responds poorly to conventional treatments, and there is an urgent medical need for new treatments. Recent preclinical studies demonstrate that cannabinoid agonists suppress established chemotherapy-evoked neuropathy. ⋯ Chemotherapy-induced neuropathic pain is particularly resistant to currently available treatments. This pilot trial found a number needed to treat of five and an average decrease of 2.6 on an 11-point NRS-PI in five "responders" (as compared with a decrease of 0.6 with placebo) and supports that it is worthwhile to study nabiximols in a full randomized, placebo-controlled trial of chemotherapy-induced neuropathic pain.

ReviewSymptomatology and pathogenesis of different types of pain in multiple sclerosis.
Multiple sclerosis (MS) is a progressive disease of the central nervous system. It is characterized by disseminated foci of demyelination, which are responsible for the diverse clinical picture of MS. Pain is a frequent but underestimated symptom of multiple sclerosis. ⋯ The pain experienced by MS patients is generally caused by nervous system damage during the course of the disease process and can usually be characterized as central neuropathic pain (less frequently as peripheral or nociceptive pain). The most frequent symptoms include dysesthetic extremity pain, painful tonic spasms, Lhermitte's sign, trigeminal neuralgia, headaches and low back pain. This paper discusses the probable mechanisms behind the development of pain in MS, the prevalence, classification, types of pain, as well as the most effective treatment methods.

ReviewCapsaicinoids in the treatment of neuropathic pain: a review.
The treatment of neuropathic pain is difficult. Oral pharmaceuticals have significant side effects, and treatment efficacy tends to be modest. The use of topical analgesics reduces the potential for systemic side effects and allows direct application of medications to the area of pain. ⋯ While low-dose capsaicin has not resulted in good efficacy, the larger dose 8% topical capsaicin has had some of the best data currently available in the treatment of post-herpetic neuralgia (PHN) and other neuropathic conditions. This paper discusses the data currently existing for capsaicin 8% in the treatment of PHN. It further reviews data for the low-dose capsaicin products and the current status in the development of other capsaicinoids, e.g. resiniferotoxin, and high-concentration liquid capsaicin.

ReviewPeroxisome proliferator-activated receptor agonists modulate neuropathic pain: a link to chemokines?
Chronic pain presents a widespread and intractable medical problem. While numerous pharmaceuticals are used to treat chronic pain, drugs that are safe for extended use and highly effective at treating the most severe pain do not yet exist. Chronic pain resulting from nervous system injury (neuropathic pain) is common in conditions ranging from multiple sclerosis to HIV-1 infection to type II diabetes. ⋯ Experimental evidence suggests a connection between the pain ameliorating effects of PPAR agonists and suppression of inflammatory gene expression, including chemokines. In early clinical research, one PPARα agonist, palmitoylethanolamide (PEA), shows promise in relieving chronic pain. If this link can be better established, PPAR agonists may represent a new drug therapy for neuropathic pain.
