Active clinical trials for "Neuralgia"

Observational study to assess the effectiveness and use of pregabalin (Lyrica) in the treatment of patients with peripheral neuropathic pain in real-life daily clinical practice.

The purpose of this study is to assess whether a cross-over type study design in post-traumatic neuropathic patients can be used to assess the activity of potential analgesic agents

Recent advances in the field of pain psychophysics that have enhanced the understanding of pain processing by the nervous system seem to characterize the individual pattern of pain processing, thereby enabling the prediction of a person's susceptibility to develop chronic pain consequent to surgery. In this project, the researchers propose to apply a wide array of advanced testing methods in order to prospectively assess the pain modulation pattern of pain free patients about to undergo an elective thoracotomy. Since about half of post-thoracotomy patients suffer from chronic neuropathic postoperative pain, the researchers expect to identify which tests predict a risk for this pain and the relative power of the relevant tests in this prediction, and to construct a short and applicable tool, the 'pain susceptibility profile', that will reliably predict the risk for the development of pain. The expected results of this project will serve the field of pain prevention by identifying patients at risk and tailoring interventions to reduce the risk of chronic pain.

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.

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.

The nature of trigeminal neuralgia (TN) is fluctuating and patients can experience periods of complete remission of pain as well as periods with excessive pain. TN is often triggered by innocuous intra- and extraoral stimuli such as chewing. Since the first-line prophylactic drugs, i.e. carbamazepine and oxcarbazepine, are administered orally, medical treatment of TN can be problematic in periods of exacerbation. In cases of severe exacerbation, patients oftentimes become dehydrated and anorectic as eating and drinking will evoke pain. Treatment with drugs administered intravenously is needed in such situations. Phenytoin was the first drug to be used for TN but it is rarely used as long-time preventative because of frequent side-effects associated with long-term use. However, phenytoin has the advantage over other drugs, that it can be administered also intravenously as fosphenytoin (the prodrug of phenytoin). By clinical experience the efficacy is very good. However, evidence of the treatment is lacking as only case reports including a total of 5 patients described the effects and side effects with pain relief lasting two days. By providing solid observational evidence, the treatment can be considered for incorporation in local and international treatment guidelines. The aim of the study is to test the hypothesis that fosphenytoin loading reduces TN pain with at least 50 % in 80% of patients with trigeminal neuralgia experiencing exacerbation of TN pain. The study is a descriptive prospective observational pilot study with 3 months followup period.

There is a significant debate whether local infiltration techniques may be a method to treat complicated chronic pain syndromes, e.g. refractory headache. Until now there is a lack of evidence regarding efficacy of this treatment especially in long term follow up. Similarly, indication and management are under debate. Aim of this trial is to analyse pain scores during first treatment with anaesthesiological infiltration series.

The purpose of this study is to evaluate the effect of pregabalin on patient reported outcomes compared with conventional analgesic care in chronic cervical pain patients with accompanying upper limb radiating pain (neuropathic component) treated in primary care settings under routine clinical practice.

Targeted SCS is a standard and safe interventional pain procedure that is offered to patients with intractable neuropathic pain for their symptomatic relief. The known and reported complications include technical failure to perform the procedure, failure to gain symptomatic relief, trauma to nerve, and infection. These risks are very low in incidence and part of any interventional pain procedure in the spine. PET-CT scan involves insertion of a cannula and administration of a dye (FDG) as a contrast in a patient who has been fasted for at least 6 hours. The procedure is lengthy and can take up to 2 to 3 hours. This includes a 30-60 minute resting time following the injection of contrast. The actual scan itself takes up to 30 minutes. There is a small chance of pain and redness at the injection site. Allergic reaction to the radio-contrast is rare and is usually mild. Patients with known allergy to FDG will not be recruited in the study. Some patients can feel claustrophobic at the time of the scan which can make them feel anxious. The PET-CT scan involves radiation with associated risks as detailed in the previous section. All these risks will be explained to the patients at the time of the informed consent.

The study is a non-interventional prospective observational study in patients with trigeminal neuralgia that undergoes micovascular decompression. The aim is to evaluate the efficacy and complications 2 years after microvascular decompression
