Filter by:The purpose of this study is to evaluate three different injectable solutions used to block ankle nerves to manage ankle pain. The current standard of medical care is to inject a combination of local anesthetics and steroids around injured nerves. There is evidence that injection of local anesthetic (without the steroid) can calm the injured nerve and provide pain relief from a few days up to a few months. Injection of sterile salt water also has the potential to provide pain relief by breaking scar tissue around the nerve thereby relieving compression. Injections of local anesthetic and steroids around injured nerves have been used for many years to provide relief of pain but the specific reason is not well known for this benefit. There are three possibilities: 1) Steroids can reduce inflammation and calm the nerves, 2) local anesthetics can have similar actions but with shorter duration (few days), and 3) injection of any solution can break scarring around an injured/compressed nerve. The study will compare pain relief and possible adverse effects from these three different solutions. This study will help provide definitive answers regarding pain relief and possible adverse effects of the three solutions. This, in turn, will determine the best possible option for injection in patients with nerve-related injury pain.
A Randomized, Double-blind, Active-Controlled, Multi-center, Phase 3 Trial to Compare the Safety and Efficacy between YHD1119 and Pregabalin in Patients with Peripheral Neuropathic Pain
The BlueWind Reprieve system is a neurostimulator consisting of an Implant and external components. The system is intended for home care use. The chronic pain treatment is achieved by an electrical stimulation of peripheral nerve fibers. The stimulation is set so that it generates paresthesia in the stimulated area (e.g. foot), reducing the pain sensation and improving the quality of life for the patient.
Currently, it is established that the voltage-gated calcium channels modulate pain perception due to an influence on the neuronal transmission and excitability. In the past, attention has focused on the modulation of high voltage activated calcium channel. More recently, scientific interest has proven to the low voltage activated calcium channel, also called T-type channels. The data from the literature show significant involvement of these channels in the physiology of nociception and pathophysiology of acute and chronic pain. Moreover, in several animal pain models (acute, neuropathic, inflammatory), T-type channels inhibition alleviates painful behaviours. Analgesics treatments available in clinic are ineffective in some patients with chronic pain (neuropathic, inflammatory) and often induce deleterious side effects. Thus, the clinical use of selective inhibitors of T-type channels could not only help the development of new therapies for the treatment of neuropathic pain (prevalence = 5-8 %), but also have a pharmaco-economic impact due to the low selling price of their inhibitor currently available: Zarontin®. The purpose of this study is to assess the effectiveness of ethosuximide (Zarontin®) on the pain symptoms and quality of life in patients with peripheral neuropathic pain compared to a control group.
This non-interventional study will evaluate the efficacy, tolerability, health related quality of life and use of health resources associated with QUTENZA treatment when QUTENZA is used in standard clinical practice. The patient's primary diagnosis of peripheral neuropathic pain (PNP) will be classified into subtypes: post-herpetic neuralgia (PHN); HIV-associated neuropathy (HIV-AN); neuropathic back pain; cancer-related neuropathic pain; post-operative & post-traumatic neuropathic pain; and 'other' neuropathies.
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.
Background: - Docetaxel, the most commonly used drug for the treatment of invasive breast cancer, has been shown to prolong the lives of women with breast cancer and prevent the cancer from spreading or returning. However, docetaxel is known to cause nerve damage, including numbness, tingling, and pain, in 50 to 90 percent of breast cancer patients. This nerve damage is called peripheral neuropathy, and can be so severe that treatment with docetaxel may need to be stopped. Researchers are interested in studying docetaxel-related nerve damage to determine whether certain genetic factors may predispose women to developing this condition, and to more closely investigate the specific effects of docetaxel on the nervous system Objectives: - To examine nerve damage in women with breast cancer who are being treated with docetaxel. Eligibility: - Women at least 18 years of age who have been diagnosed with invasive breast cancer and are scheduled to have docetaxel treatment. Design: - Participants will be screened with a full medical history and physical examination, as well as blood and urine tests and imaging studies. - This study requires seven visits, one before the start of chemotherapy and six after the scheduled treatment visits. Study procedures at each visit will take 30 to 45 minutes and will be done in parallel with scheduled chemotherapy visits. - At the first visit, participants will provide blood samples; complete questionnaires to rate and describe any existing pain, numbness, or tingling in hands and feet before the start of chemotherapy; have nerve conduction tests; and have a skin biopsy. - At each visit following docetaxel treatment, participants will complete questionnaires to rate and describe any pain, numbness, or tingling during the course of chemotherapy. Participants will provide blood samples at every visit and have nerve conduction tests during the second, fourth, and sixth visits. Participants will also have a second skin biopsy, either from a site that appears to be experiencing nerve damage or (for those who are not developing nerve damage symptoms) from a site near the first biopsy location.
The purpose of this study is to investigate the effect of AZD3161 on mechanical pain sensitivity and axon reflex flare in normal and ultraviolet C irradiated skin.
