Lumbar radicular pain after disc herniation may be associated with release of pro-inflammatory cytokines from nucleus pulposus (NP) tissue. In the present study we examined the role of interferon-γ (IFN-γ) and cluster of differentiation 68 (CD68) in the acute phase of this process. First, in an animal model mimicking the clinical situation after disc herniation, the role of IFN-γ close to the dorsal nerve roots was studied. Next, in patients with lumbar radicular pain due to disc herniation, we examined how two single nucleotide polymorphisms (SNPs; rs2069705 and rs2069718) are important for the IFN-γ expression influenced the pain behavior...

BACKGROUND: Recent systematic reviews have demonstrated that pain associated with knee osteoarthritis (OA) is a complex phenomenon that involves various contributors. People with knee OA exhibit symptoms of impaired body-perception, including reduced tactile acuity, impairments in limb laterality recognition, and degraded proprioceptive acuity. The Fremantle Back Awareness Questionnaire (FreBAQ) was developed to assess body-perception specific to the back in people with chronic low back pain...

In both acute and chronic pain conditions, women tend to be more sensitive than men. This sex difference may be regulated by estrogens, such as estradiol, that are synthesized in the spinal cord and brainstem and act locally to influence pain processing. To identify a potential cellular source of local estrogen, here we examined the expression of aromatase, the enzyme that catalyzes the conversion of testosterone to estradiol. Our studies focused on primary afferent neurons and on their central targets in the spinal cord and medulla as well as in the nucleus of the solitary tract, the target of nodose ganglion-derived visceral afferents...

BACKGROUND: The foot and ankle represent a common site for tophi in people with gout, yet it is unclear whether the presence of tophi is related to impaired muscle function. This study aimed to determine the association between foot and ankle tophi and muscle force in people with gout. METHODS: Participants with gout were stratified into two groups based on the presence of clinically-evident tophi affecting the foot or ankle on physical examination. Isometric muscle force for plantarflexion, dorsiflexion, inversion and eversion was measured using static dynamometry...

Activated microglia secrete an array of pro-inflammatory factors, such as prostaglandins, whose accumulation contributes to neuronal damages. Prostaglandin endoperoxide synthases or cyclooxygenases (COX-1 and COX-2), which play a critical role in the inflammation, are the pharmacological targets of non-steroidal anti-inflammatory drugs, used to treat pain and inflammation. Since it was reported that COX-1 is the major player in mediating the brain inflammatory response, the aim of this study was to evaluate the effects of highly selective COX-1 inhibitors, such as P6 and mofezolac, in neuroinflammation models...

BACKGROUND: Patient-reported outcomes are increasingly used as complementary measures to clinical outcomes in total knee arthroplasty (TKA). However, their prognostic importance has yet to be established. We aimed to determine whether the long-term revision risk in TKA relates to pain and Knee Society Score (KSS) measures at baseline, 1, and 2 years. METHODS: This was a registry-based study of primary TKA procedures at a large tertiary care institution between 1995 and 2010...

The most used therapeutic treatment to relieve neuropathic pain is that of neuromodulators such as anti-epileptics or anti-depressants; however, there are alternatives that may be potentially useful. The sigma-1 receptor is a therapeutic target that has shown favorable results at preclinical levels. The aim of this study was to evaluate the anti-hyperalgesic effect of N-(2-morpholin-4-yl-ethyl)-2-(1-naphthyloxy) acetamide (NMIN) in a chronic constriction injury model (CCI) and compare it both a sigma-1 antagonist (BD-1063) and also Gabapentin, as well as determine its possible role as an antagonist of sigma-1 receptors...

BACKGROUND: Majority of the progress and development in palliative care in the last decade has been improvements in physical aspects of treatment, namely pain and symptom management. Psychosocial aspects of care have improved, although not enough to meet the needs of many patients and family members. This is evident in many parts of the world and notably in Singapore, where palliative care is seen as an emerging medical and nursing specialty. AIM: To discuss the implementation of the SAGE and THYME communication model in a palliative care context...

Context • Pain from osteoarthritis is associated with peripheral nociception and central pain processing. Given the unmet need for innovative, effective, and well-tolerated therapies, many patients, after looking for more satisfactory alternatives, decide to use complementary and alternative modalities. The analgesic mechanism of subcutaneous injections of diluted bee venom into an acupoint is thought to be part of an anti-inflammatory effect and the central modulation of pain processing. Objectives • Using the rat model of collagenase-induced osteoarthritis (CIOA), the study intended to investigate the analgesic effects of bee venom acupuncture (BVA) as they are related to the acupuncture points and dosage used and to determine whether the analgesic mechanisms of BVA for pain were mediated by opioid or adrenergic receptors...

Methionine enkephalin ([Met(5)]-enkephalin, Opioid growth factor (OGF)) is a small neuropeptide with growth-related as well as immunomodulatory properties. OGF is distributed widely throughout the body, is both autocrine and paracrine produced, and has a very short half-life in serum. In addition to its neurotransmitter functions, OGF inhibits cell replication of a wide variety of cells involved in the autoimmune process. In this preclinical study, mice were immunized with myelin oligodendrocytic glycoprotein (MOG35-55) to establish a chronic progressive form of autoimmune encephalomyelitis (EAE), and serum enkephalin levels were assessed throughout the disease as well as in response to OGF therapy in order to determine whether OGF may be a biological marker for EAE and multiple sclerosis...
