Filter by:Effective treatment of acute pain, chronic and persistent is the most important concern in the world today. Although a variety of pain medications including anti-inflammatory painkillers and opiouids, patients continue to suffer from pain constantly. For over a century ,International committees studied the issue of cannabis, and almost uniformly recommended the use of cannabis for various medical applications ,especially those that include pain treatment. Despite the widespread use of THC in clinical practice, there are few studies on the efficacy of THC In a double-blind, randomized trial. In addition, few studies examined the effect of THC on the experience pain in healthy subjects and most of them did not find an effect on pain experimental induced by capsain. so checking other models of pain such as thermal pain and mechanical pain in addition to checking the influence on the regulation of pain will contribute to understanding the mechanism of action of THC. Understanding the mechanism of action of THC in relieving pain will lead to predicting who will benefit from this treatment and direct patients for selection of appropriate medication according to the damaged mechanism.
Investigators aim to identify the key phenotypes (biological, psychological, genetic) involved in the transition from acute to chronic neuropathic pain (NP) by comparison of the neuropathic pain phenotypes and genomics of patients developing NP or not under similar nerve injury conditions. The cohort is part of a previous prospective study of 1000 patients operated for breast cancer of whom 350 have surgeon defined intercostobrachial nerve resection during operation with or without persistent pain and additional 50 patients with pain, but no nerve resection during operation. Patients fill in questionnaires and a detailed sensory examination, cognitive tests, and a cold water test with autonomic nervous system monitoring are performed during the research visit. A selected group of patients undergo quantitative sensory testing (QST).
Numerous surveys have shown that following breast surgery, longterm pain affects around half of patients. Given that 1 in 9 women will get breast cancer and that surgery is the cornerstone of treatment, persistent pain represents a major challenge. In addition to the suffering chronic pain causes to individual patients, the investigators know that it places a substantial burden on families and carers, and that patients with pain represent an excessive demand on healthcare resources. This research will evaluate the impact of introducing a proactive, integrated care plan for patients having breast surgery. It will assess the effect of the care plan on reducing the number of patients with pain at 3 and 12 months after their procedure. The personalised plan involves numerous evidence based steps linked by a single unifying description aimed at controlling pain, before, during and after the procedure, in hospital and at home. Patients at risk of developing pain will be identified prior to the procedure and randomly allocated to follow either the personalised care plan or to receive 'usual' care. In the personalised care plan group, participants will get information about chronic pain, be screened for pain and offered immediate treatment. During their procedure both the surgeon and the anaesthetist will offer treatments such as nerve numbing procedures that reduce the likelihood of experiencing pain. After their procedure, patients will be again screened for pain and further treatment instigated. Physiotherapists and other allied health professionals such as psychologists will also be involved as appropriate. A package of care for pain will then be passed on to the patients' GP, in the form of a written pain management plan, for ongoing care which will be linked to the hospital. Patients from both groups will be followed up for a year at regular intervals.
The purpose of this study is to evaluate the efficacy of cortical stimulation (CS) as an adjunctive treatment for chronic neuropathic pain.
Neuropathic pain is difficult to control because it is only partially sensitive to opioid analgesics, and requires the addition of other therapies such as antidepressants and epileptics. Ziconotide is a drug that is used to treat neuropathic pain in patients who have had inadequate pain control with prior combination of medicines.
The investigators propose to compare plasma protein profiles for SCI patients with/without chronic neuropathic pain in order identify biomarker(s) that are associated with this medical condition. Secondly, the investigators propose to identify a temporal relationship to initial SCI at which these biomarkers manifest. Our working hypothesis is that sustained alterations in specific inflammatory molecules are associated with chronic neuropathic pain following SCI, and that their plasma levels can serve as biomarkers to identify patients at risk for the development of neuropathic pain. Additionally the investigators are collecting skin tissue biopsy samples from patients following acute and chronic spinal cord injury to create vector-free human iPS cells from fibroblasts by direct delivery of reprogramming proteins.
