Active clinical trials for "Peripheral Nervous System Diseases"

This study will examine how the brain processes pain signals and how the different parts of the brain work with each other in response to painful stimuli. A better understanding of how people experience pain may be helpful in developing more effective treatments. Healthy normal volunteers, patients requiring third molar (wisdom tooth) extraction, and patients with persistent pain due to disease, injury or other reason may be eligible for this study. Participants will receive one or more of the following sensory stimuli, which may cause brief discomfort or pain: Heat/Cold - applied by an electronically controlled device that touches the skin, or by temperature-controlled water baths, or by a thermally controlled brass cylinder the subject grasps Capsaicin (active ingredient in hot chili peppers) - injected in a small volume of fluid under the skin or into a muscle Mechanical stimulation - brushings or vibrations that do not normally cause pain Ischemic stimulation - inflation of a blood pressure cuff on the arm or leg for up to 30 minutes These stimuli will be applied both before and during positron emission tomography (PET) scanning. This test shows which parts of the brain are active and which are not and is important for studying how different parts of the brain work together to feel and react to specific sensations. For this procedure, the subject lies on a table in the PET scanner while a series of scans are taken during different sensory conditions. At the beginning of each scan, radioactive water is injected into an arm vein through a catheter (a thin plastic tube). A special camera records the arrival and disappearance of the radiation in various brain areas, creating a picture of the brain's activity in various regions. Oral surgery patients may have PET scans both before and after their wisdom tooth extraction. Alfentanil, a commonly used narcotic pain reliever, will also be given during the PET procedure to determine how the brain responds to sensory stimuli while under the effects of a pain killer. Participants will also have a magnetic resonance imaging (MRI) scan of the brain to help interpret the PET results. MRI uses a magnetic field and radio waves to show structural and chemical changes in tissues. During the scan, the subject lies on a table in a cylindrical machine (the scanner). He or she can speak with a staff member via an intercom system. Some sensory studies may require placing an arterial and/or intravenous line. Following injection of a local anesthetic, a catheter is placed in an artery in the arm. At regular intervals during various sensory stimuli, small blood samples are drawn from the artery to measure blood gases and other substances. Samples may also be drawn from a catheter placed in a vein. Subjects may also have ultrasound monitoring to evaluate blood flow in the arteries, veins and brain. A gel is spread over the skin above the blood vessel and a hand-foot-and-mouth device is placed on the gel. The device emits high-frequency sound waves to produce a picture of the speed of blood flow in the artery and the diameter of the vessel.

Study is designed to assess the efficacy and safety of memantine XR and pregabalin in reducing neuropathic pain in patients with chemotherapy-induced peripheral neuropathy (CIPN) caused by prior treatment with any chemotherapy as measured by the Brief Pain Inventory- Short Form (BPI-SF). It will also determine the influence of these drugs on peripheral neuropathy-related functional status and quality of life (QOL) as measured by the EORTC QLQ-C30.

The purpose of the study is to determine the validity of a point-of-care nerve conduction device (NeuroMetrix) and Rydel-Seiffer tuning fork in assessing the level of peripheral neuropathy in patients with chemotherapy-induced peripheral neuropathy (CIPN). Chemotherapy-induced peripheral neuropathy (CIPN) is a common, persistent toxicity among patients who receive chemotherapy. It is characterized by a variety of sensory and motor symptoms such as numbness, tingling, reduced sense of touch, reduced proprioception (awareness of your limb and body position in space), pain, weakness, balance disturbances, and deficits in motor skills.

The trend of diabetes prevalence was increased by comparing these two national surveys in 2009 and 2014. However, the studies only focused on the prevalence and risk of diabetes and non-communicable diseases in Myanmar. The study focused on the common complications of Diabetic Peripheral Neuropathy (DPN) is rare. The studies in other countries showed high prevalence rate and under-diagnosis of DPN. Most of the patients with DPN did not complain about their symptoms because of without prominent symptoms. DPN is the major complication of diabetes. According to the international studies, DPN has the hidden epidemic and is the common causes which can lead to disability and decreased the quality of life in diabetes. Therefore, the study focused on the prevalence of DPN and its impact on the ADLs is obligatory as the descriptive study to explore the actual situation. Nursing care is not only for the patients in the hospital but also for the people in the community. Moreover, the nurses have to focus on all levels of prevention. Diabetes is the lifelong diseases and accessibility of health care for everyone with diabetes is a very important issue in the era with increased prevalence of diabetes. Therefore, we all have to focus not only on the primary prevention but also on the secondary and tertiary prevention of diabetes. The secondary and tertiary prevention in the diabetic patients also means the primary prevention of other diseases and disabilities (the complications of diabetes). For diabetic neuropathic patients, maintaining normal daily living is very important liked everyone. The objective of this study is to evaluate the prevalence of DPN and DPNP in type 2 diabetic patients and impact on the activities of daily living. The descriptive, cross-sectional study design will be used in this study. The inclusion criteria are the person aged over 25 years of age who had already diagnosed type 2 diabetes mellitus, taking any anti-glycemic treatment. The persons who are suffering from neuropathy and neuropathic pain other than diabetes, severe illness of diabetic patients, mental illness and alcoholism will be excluded from this study. The patients who meet the inclusion criteria and come to outpatient diabetic clinics at YGH, NOGH, EYGH, and WYGH will be chosen as a sample after obtaining informed consent. Data collection will be done at this outpatients diabetic clinic of these four hospitals. This study has already obtained ethical clearance from Nursing Science Ethical Review Committee, Graduate School of Health Sciences, Okayama University, Japan with the review number D1605. It will be carrying out after obtaining approval from Department of Medical Research, Myanmar. At the outset, informed consent will be obtained with detailed information about the purpose of research, the part they need to participate, possible benefits and their rights to withdraw.

This single group study was conducted to test the feasibility and acceptability of implementing an exercise intervention during oxaliplatin infusion across three months of oxalipatin-based chemotherapy in patients with gastrointestinal malignancies.10 patients were enrolled onto this study and validated questionnaires were used to evaluate the feasibility and acceptability of the intervention and collect patient-reported outcomes over the course of study enrollment.

Patients with diabetes mellitus and definite autonomic and peripheral neuropathy were randomized to receive quinapril or no treatment for 2 years.

Diabetic foot ulceration (DFU) is a common and largely preventable complication. While most of these ulcers can be treated successfully, some will persist and become infected. Ultimately, nearly one fifth of patients with infected lower-extremity diabetic ulcers will require amputation of the affected limb.Prevention by identifying people at higher risk is the key for better clinical management of such patients. It is not uncommon for patients suffering from diabetes to have concomitant lower extremity edema or even venous insufficiency and they subsequently may benefit from graduated compression. However, because of the common association of peripheral arterial disease (PAD) in patients with diabetes, most clinicians are reluctant to apply compressive dressings in fear of exacerbating the symptoms of PAD and the possible resulting gangrene. A novel micro-mobile foot compression device named Footbeat (AVEX, Inc.) offers alternative means providing lower extremity compression. This device is portable and can be used in a standard diabetic shoes on daily basis, which in turn may improve venous blood and relief from concomitant lower extremity edema. In addition, potential improvement in lower extremity blood flow in response to regular foot compression, could improve balance, gait, skin perfusion, plantar sensation, and overall daily physical activities (e.g. number of taken steps per day, duration of standing, etc). The purpose of this study is to conduct an observational study with N=30 ambulatory patients with diabetes and loss of protective sensation to assess whether this micro-mobile foot compression device can help improving motor function, lower extremity perfusion, and vascular health.

This pilot clinical trial studies scrambler therapy in treating pain and peripheral neuropathy in patients previously treated with chemotherapy. Scrambler therapy may help relieve pain from peripheral neuropathy caused by chemotherapy

The purpose of this clinical trial conducted in patients suffering from chronic pain is to study the relationship between individual patients' profile and their analgesic response

The primary objective of the study is to clarify factors affecting the incidence of peripheral neuropathy in patients treated with HALAVEN. A total of 590 patients will be enrolled in this study with 295 patients in the treatment group of primary or secondary chemotherapy and 295 patients in the treatment group of tertiary or later chemotherapy.
