Role of NFκB in an Animal Model of Complex Regional Pain Syndrome–type I (CRPS-I)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: NFκB is involved in several pathogenic mechanisms that are believed to underlie the complex regional pain syndrome (CRPS), including ischemia, inflammation and sensitization. Chronic postischemia pain (CPIP) has been developed as an animal model that mimics the symptoms of CRPS-I. The possible involvement of NFκB in CRPS-I was studied using CPIP rats. Under sodium pentobarbital anesthesia, a tourniquet was placed around the rat left ankle joint, producing 3 hours of ischemia, followed by rapid reperfusion (IR injury). NFκB was measured in nuclear extracts of muscle and spinal cord tissue using ELISA. Moreover,...

How Neuroimaging Studies Have Challenged Us to Rethink: Is Chronic Pain a Disease?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: In this review, we present data from functional, structural, and molecular imaging studies in patients and animals supporting the notion that it might be time to reconsider chronic pain as a disease. Across a range of chronic pain conditions, similar observations have been made regarding changes in structure and function within the brains of patients. We discuss these observations within the framework of the current definition of a disease.Perspective: Neuroimaging studies have made a significant scientific impact in the study of pain. Knowledge of nociceptive processing in the noninjured and injured central nerv...

Central Sensitization: A Generator of Pain Hypersensitivity by Central Neural PlasticityEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Central sensitization represents an enhancement in the function of neurons and circuits in nociceptive pathways caused by increases in membrane excitability and synaptic efficacy as well as to reduced inhibition and is a manifestation of the remarkable plasticity of the somatosensory nervous system in response to activity, inflammation, and neural injury. The net effect of central sensitization is to recruit previously subthreshold synaptic inputs to nociceptive neurons, generating an increased or augmented action potential output: a state of facilitation, potentiation, augmentation, or amplification. Central sen...

Moderate Exercise Increases Expression for Sensory, Adrenergic, and Immune Genes in Chronic Fatigue Syndrome Patients But Not in Normal SubjectsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Chronic fatigue syndrome (CFS) is characterized by debilitating fatigue, often accompanied by widespread muscle pain that meets criteria for fibromyalgia syndrome (FMS). Symptoms become markedly worse after exercise. Previous studies implicated dysregulation of the sympathetic nervous system (SNS), and immune system (IS) in CFS and FMS. We recently demonstrated that acid sensing ion channel (probably ASIC3), purinergic type 2X receptors (probably P2X4 and P2X5) and the transient receptor potential vanilloid type 1 (TRPV1) are molecular receptors in mouse sensory neurons detecting metabolites that cause acute musc...

L2 Spinal Nerve–Block Effects on Acute Low Back Pain From Osteoporotic Vertebral FractureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Elderly patients with osteoporosis sometimes experience lumbar vertebral fracture and may feel diffuse nonlocalized pain in the back, the lateral portion of the trunk, and the area surrounding the iliac crest. The pattern of sensory innervation of vertebral bodies remains unclear. Some sensory nerves from the L2 and L5 vertebral bodies may enter the paravertebral sympathetic trunks and reach the L2 dorsal root ganglion. Our randomized controlled study was to clarify the effect of L2 spinal nerve block on low back pain originating from acute osteoporotic lumbar vertebral fracture. Patients with low back pain origi...

Does Pain Catastrophizing Moderate the Relationship Between Spinal Nociceptive Processes and Pain Sensitivity?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Existing evidence indicates that pain catastrophizing is associated with enhanced pain reports and lower pain threshold/tolerance levels, but is not significantly related to nociceptive flexion reflex (NFR) threshold in healthy and clinical pain samples. This suggests pain catastrophizing may modulate pain threshold at a supraspinal level without influencing descending modulation of spinal nociceptive inputs. To examine this issue further, the present study assessed NFR threshold, electrocutaneous pain threshold, and electrocutaneous pain tolerance, as well as subjective ratings of noxious stimuli in a sample of ...

Cortical Reorganization in Primary Somatosensory Cortex in Patients With Unilateral Chronic PainEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Bodily representations of the primary somatosensory (SI) cortex are constantly modified according to sensory input. Increased input due to training as well as loss of input due to deafferentation are reflected as changes in the extent of cortical representations. Recent studies in complex regional pain syndrome (CRPS) patients have indicated that the chronic pain itself is associated with cortical reorganization. However, it is unclear whether the observed reorganization is specific for CRPS or if it can be detected also in other types of chronic pain. We therefore searched for signs of cortical reorganization in...

Understanding Fibromyalgia: Lessons from the Broader Pain Research CommunityEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Fibromyalgia (FM) is a chronic pain condition marked by centrally mediated augmentation of pain and sensory processes. Skepticism has marked the history of this condition, but more recent study has identified neurobiological underpinnings supporting many of the symptoms associated with this condition. Early research in FM had unprecedented latitude within the rheumatology community to borrow heavily from theory and methods being applied in chronic pain research more generally. These insights facilitated rapid advances in FM research, not the least of which was the abandonment of a peripheral focus in favor of stu...

Abstract: Fibromyalgia syndrome (FMS) is a chronic pain disorder associated with widespread musculoskeletal pain, tenderness, and fatigue. Additionally, correlational research suggests negative affect (eg, depression, anxiety) and deficits in positive affect may contribute to FMS symptomatology. However, well-controlled, experimental research is necessary to ascertain whether patients with FMS have problems in affective processing. The present study used a well-validated picture-viewing paradigm to evoke emotional responses in 17 patients with FMS and 17 sex- and age-matched healthy control participants. Each participant v...

Structure of Posttraumatic Stress Disorder Symptoms in Pain and Pain-Free Patients Scheduled for Major SurgeryEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Factor-analytic studies of the structure of posttraumatic stress disorder (PTSD) symptoms have yielded inconsistent results. One of the reasons for the inconsistency may be that PTSD is highly comorbid with other disorders; the observed factor structure might depend on the particular comorbid disorder. One such disorder is chronic pain. The goal of the present study was to investigate whether PTSD symptom structure differs between pain and pain-free patients scheduled to undergo major surgery. Four hundred and forty-seven patients who were approached 7 to 10 days prior to scheduled surgery completed the PTSD Chec...

Chemotherapy-Induced Peripheral Neuropathy as a Predictor of Neuropathic Pain in Breast Cancer Patients Previously Treated With PaclitaxelEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Neuropathic pain (NP) remains difficult to control for a significant number of patients with cancer. Chemotherapy-induced peripheral neuropathy (CIPN) has been postulated as an initial stage in the development of NP.
