Active clinical trials for "Neuralgia"

The purpose of this study is to demonstrate safety and efficacy of a new spinal cord stimulation paddle electrode which is able to target the dorsal horns, dorsal nerve roots, and dorsal columns. The research electrode ("Study Electrode") is designed to answer basic physiological clinical research questions. It may inform future device therapy development, but the Study Electrode is not a product that will be marketed or sold. The Investigators believe the protocol is a Non-Significant Risk study answering basic physiological research questions, which may be performed under hospital IRB approval.

Epidural injection will be completed under fluoroscopy and all patients will receive 1-4 mg of Midazolam for relaxation before procedure and, if needed, 50-100 mcg of Fentanyl intravenous (IV). Radiopaque contrast (Omnipaque 300), for confirming the epidural position of the needle, steroids and local anesthetic agents will be used according to the physician performing the block and will not be controlled by the study. Patients will be randomly assigned to receive either inhaled Entonox along with the interventional block they are scheduled for or oxygen. They will be blinded about the treatment they are receiving. Those randomized to Entonox will inhale the gas through a mouthpiece throughout the procedure and also continue to receive it for a total of 4 hours in the recovery. Those randomized to the oxygen group will receive oxygen through a similar mouthpiece for the entire duration of the procedure and recovery for 4 hours. Following completion of procedure the patient will be transferred to recovery and monitored for 3-5 hours then discharged home with instructions. Possible side effects will be monitored and recorded, pain score of patient will be recorded before discharge. All the patients will receive standard instructions regarding physical back exercises. This will be repeated for every procedure up to maximum of three blocks. The patients will be followed during each block and over a period of 1, 3, 6 and 12 months and on each follow-up visit will complete computerized set of questionnaires as they did before the procedure. The patients charts will be then reviewed for one year after the initial procedure to determine if further epidural steroid injections or surgery for the presenting problem were required. It is anticipated that the appropriate number of patients will be enrolled within six months of study initiation.

In this study the investigators aim to examine the effects of Transcranial Direct Current Stimulation (tDCS) on pain levels as well as the changes in cognitive (thought) processing in individuals with chronic pain of the cornea -- and also compared with healthy controls.

The purpose of this study is to assess the safety and tolerability of long term therapy with Sativex® in relieving neuropathic pain.

Researchers are looking for a better way to treat people who have diabetic neuropathic pain (DNP). DNP is pain due to damage to the nerves in the extremities that can occur in patients with diabetes as a result of blood sugar levels being too high for too long. BAY2395840 works by blocking specific receptors. A receptor is a protein inside or on the surface of a cell that binds to a specific substance and causes a specific effect in the cell. BAY2395840 specifically blocks so-called bradykinin B1 receptor, whose activation is involved in inflammatory responses. This blockage may help to relieve pain and inflammation. BAY2395840 has already been studied in clinical studies with European people. However, data for Japanese people are still missing. The participants of this study do not benefit from this study. However, the study will provide information on how to use BAY2395840 in later studies with Japanese people. The main purpose of this study is to learn how safe the study drug BAY2395840 is and how it affects the body if given in single and in repetitive doses to Japanese healthy male participants. To answer this question, the researchers will collect and analyze the medical problems the participants have after taking BAY2395840 and that may or may not be related to the study treatments. These medical problems are also known as "adverse events". In addition, the study team will learn how BAY2395840 moves into, through and out of the body if given in single and in repetitive doses to Japanese healthy male participants. For this, the researchers will collect data on: the (average) highest level of BAY2395840 in the blood (also referred to as Cmax) the (average) total level of BAY2395840 in the blood (also referred to as AUC) during the treatment period with the study drug on day 1 and for the repetitive dose group only (see below), on day 7. Subsequently, the study team will compare the data between those participants who received the study drug BAY2395840 (from different dosing groups) and those participants who received placebo. A placebo is a treatment that looks like a medicine but does not have any medicine in it. All study participants will be randomly (by chance) assigned to 1 of 5 treatment groups. Dependent on the treatment group, the participants will either take: a single dose of the lowest, middle and highest BAY2395840 dose (treatment groups 1 to 3) repetitive doses of the highest BAY2395840 dose (treatment group 4) or placebo (treatment group 5). The participants will take their treatments as dosage form 1 after diet 1. The treatment period with repetitive doses of BAY2395840 will be 7 subsequent days. The participants from treatment groups 1 to 3 will have an in house-period of 8 days including 7 overnight stays. The participants from treatment group 4 will have an in house-period of 12 days including 11 overnight stays. The study duration will be approximately 6 weeks per participant for dose groups 1 to 3 and approximately 7 weeks per participant for dose group 4. During the study, the study team will: take blood and urine samples do physical examinations check the vital signs such as blood pressure, heart rate, body temperature examine heart health using electrocardiogram (ECG). About 10 to 14 days after the participants take their last treatment, the study doctors and their team will check the participants' health.

Chronic neuropathic pain is a common problem for breast cancer survivors. Even with the best medical treatment, some survivors continue to experience disabling pain. It is well-established that an interdisciplinary approach is key to the treatment of some types of chronic pain, but little research has been done on the effectiveness of interdisciplinary treatments for cancer survivors with chronic neuropathic pain. The investigators will evaluate the effectiveness of an interdisciplinary approach combining medical treatment and mindfulness-based stress reduction (MBSR) to reduce disability and improve quality of life among breast cancer survivors with chronic neuropathic pain. The investigators will also evaluate the impact of the program on psychological distress, pain cognitions, biomarkers of stress and immune function, cognitive function, as well as brain structure and function.

Background Subanesthetics concentrations of lidocaine are able to produce a differential block of the ectopic discharges, but not propagation of impulses, suppressing differentially the associated neuropathic pain symptoms. The aim of this study was to investigate the differences between the analgesic effects of lidocaine 0.5% and a control group of lidocaine 0.1% on several neuroma related pain modalities. Methods Sixteen patients with neuropathic pain due to painful neuromas caused by nerve injury participated in this randomized, double-blind experiment. The patterns of sensory changes were compared before and after injection of 1 ml lidocaine 0.5% and 0.1% close to the neuroma, the sessions being 1-2 weeks apart. Spontaneous and evoked pains were assessed using a visual analogue scale (VAS), quantitative and qualitative sensory testing.

The aim of this randomized double blind, placebo controlled, crossover study is to investigate in a prospective way the effect of lidocaine in patients with trigeminal neuralgia. Included patients will undergo four weekly sessions, two of which with lidocaine (5mgs/kg) and two with placebo infusions administered over 60 minutes. Effect will be measured with pain diaries and visual analogue scales.

Nursing study, prospective, randomized, two-center open-label. Patients will be randomized into two groups during their first laying Qutenza®: Patients receiving the laying of Qutenza® without refrigerated cushion Patients receiving the laying of Qutenza® associated with a refrigerated cushion The objective of the study is to evaluate the effectiveness of the application of cold to the reduction of pain (burning) after one hour of patch installation high concentration capsaicin (Qutenza®) in patients localized neuropathic pain.
