Chronic postoperative pain is an entity that is usually neglected by anesthetists, but several studies show that the choice of anesthetic technique may interfere with this prevalence. Esmolol is a selective beta-blocker of ultra fast duration that has been studied as a perioperative venous adjuvant with antihyperalgesic and opioid sparing action. The investigators ventured the possibility of this anti-hyperalgesic effect attenuating the chronic pain syndrome post-mastectomy.
Myofascial pain alone covers 45.3% of the diagnosis of TMJ. It is defined as palpation sensitivity and regional muscle pain. Clinically muscle pain connects to myofascial trigger points.These trigger points are hypersensitive points located in a tense band of the skeletal muscle, which can be described, causing provoked or spontaneous pain. They are divided into two as active and latent. Those who cause spontaneous pain are active, and those who provoke pain are considered latent.Spasm in the chewing muscles with myofascial pain reduces the patient's pain threshold and quality of life. Therefore, patients with spasm and TMJ pain in the masticatory muscles should be examined for head and neck muscles, the presence of myofascial trigger points should be determined and the head and neck muscles should be included in physical therapy. The aim of this study was to determine the presence of myofascial trigger points in patients presenting with pain in the masticatory muscles and TMJ region, and to determine the relationship between the presence of trigger point and the degree of pain.
Spinal cord stimulation (SCS) is one of the most commonly undertaken neuromodulatory surgery techniques in the treatment of neuropathic pain. The indication for SCS is an ineffective conservative treatment of chronic pain syndromes. The effectiveness of SCS in the case of neuropathic pain is high. The positive result of SCS treatment is the reduction of previous painful symptoms by min. 50% and / or a reduction in the amount of taken analgesics and an improvement in the quality of life including sleep quality. Long-term studies estimate that in a properly selected group of patients more than 50% of patients achieve pain reduction by the required 50% and about 60% - 70% have an improvement in the quality of life and a reduction of pain. The efficacy of SCS in different modes of stimulation is evaluated. Patients receive four different types of stimulation for 2-week period - not knowing what kind of stimulation it is. It is said that in one type of stimulation they would feel parestesias and in other three they would not. Patients are not informed that beside tonic, burst and high frequency stimulation, the fourth is an off stimulation to check for placebo effect. The test is double-blinded
The purpose of this study is find out if we can use simple tests (biomarkers) to tell us if a specific child would benefit most from CBT or from the low FODMAPs diet.
Shoulder pain in people with spinal cord injury is one of the most prevalent in acute and chronic patients because of weakness in shoulder periarticular muscles, and also because of overuse of these part of the body in assistive devices. This study aims to evidence if dry needling (a physiotherapy technique) is also useful in patients with spinal cord injury, and how long it could hold out without or less pain.
SPECIFIC AIMS Pain in both youth and adults is a complex, subjective and personal experience, and remains poorly understood. One particularly perplexing dimension of some forms of pain is the tendency of pain to spread outside of an affected body site to adjacent location, and then to unaffected body sites. Such widespread pain may reflect an altered spatial tuning of somatosensory processing, such that lateral inhibition is diminished, thereby allowing pain to spread. To date, no therapies exist which are designed specifically to diminish or even reverse the spatial spread of pain. However, training in two-point discrimination holds the potential to retune spatial aspects of somatosensory processing and may represent a novel therapy for widespread pain. Thus, the present investigation will test the following aims: Aim 1. Do youth with chronic pain have disrupted spatial tuning of somatosensory processing? Deficits in two point tactile discrimination have long been noted in adults with chronic pain, but such deficits remain poorly documented in pediatric chronic pain patients. In order to determine if such deficits exist, youth with both chronic pain and healthy youth will undergo assessment of two point discrimination thresholds. Aim 2. Does two-point discrimination training result in diminished pain and disability in youth with somatic pain? After initial characterization of tactile discrimination thresholds, youth with chronic pain will participate in multiple sessions of either two-point discrimination training or a single-point spatially-directed attentional control condition. Training will involve up to 9 additional sessions. Efficacy of training will be assessed by 1) reductions in the spatial extent of pain, 2) reductions in pain intensity and unpleasantness, and 3) reductions in pain-related disability.
Background: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disorder. Some studies have indicated that acupuncture may ameliorate the symptoms of CP/CPPS. However, results are varied and range widely, perhaps due to different modes of assessment including timepoints, places of assessment, and especially subjective scales. We propose to determine the efficacy of acupuncture relative to sham acupuncture for patients with CP/CPPS, and compare different modes of assessment regarding the therapeutic effects of acupuncture. Methods: Sixty patients with CP/CPPS will be randomly assigned to receive either acupuncture or sham-acupuncture (30 patients, each). Treatment will be conducted 3 times/week, for 4 weeks. The primary outcomes will each be the change from baseline of the total NIH (National Institutes of Health) CPSI (Chronic Prostatitis Symptom Index) score associated with 3 modes of assessment: Mode 1, the scale recorded at the hospital within 10minutes after the last session of 4 weeks of acupuncture treatment, in the company of the outcome assessors; Mode 2, the scale recorded the same day, but not at the hospital; and Mode 3, the scale recorded at the hospital 1 to 3 days after the last acupuncture session. The 3 key secondary outcomes include will be the 3 modes assessment of the changes from baseline of the NIH-CPSI total scores in the acupuncture group at week 4 after treatment. Analysis was by intention-to-treat, and multiplicity was controlled for with a step-down closed-testing procedure.
Objective: The primary aim is to evaluate the efficacy of botulinum toxin A in reducing overall limb pain in patients with complex regional pain syndrome (CRPS). Additionally the investigators would like to see if quality of life is improved and disability scores decreased. Research Design: This is a double blinded, randomized cross-over study that will be conducted over a 7 month period. It is a pilot study that will include twenty subjects recruited from the Neurology CRPS clinic at VA Connecticut and from outside VA hospitals within a 150 mile radius. Subjects will receive an intramuscular injection Treatment A which is only 1% lidocaine or Treatment B which is mixture of botulinum toxin A + 1% lidocaine in the affected limb only. This is a cross over study where patients will receive Treatment A or B initially during the first of four study visits and during the third study visit while receive whichever treatment not given during the first visit. Dr. Sameer Ali, VA neurology fellow, will be blinded when administering the treatments. Dr. Hajime Tokuno, VA neurologist who is the principal investigator of the trial will prepare the treatments. Clinical pharmacy will be randomizing the treatments. Dr. Tokuno will not be blinded as he needs to know which treatment has been given in case of complications. Impact/Significance: The significance of this study is the possible discovery of a new, safer, less invasive, and more efficacious therapeutic option for patients suffering from CRPS. Currently medical management with neuropathic pain meds, interventions such as sympathetic nerve blocks and ketamine infusion has helped some patients and not others. The investigators are trying to see whether either of the two treatments and especially the treatment with botulinum toxin may be a more viable alternative than existing modalities.
The objective of this prospective, observational study is to determine the association between the composition of the gut microbiota and the severity and persistence of Complex Regional Pain Syndrome symptoms (Study A). The objective of Study B, a longitudinal study of microbiota biomarkers of patients with newly diagnosed CRPS is to determine if the researchers can predict which patients are more likely to recover compared to those who do not. A secondary objective of both studies is to examine cognitive flexibility in relation to outcomes (study A and B).
