Active clinical trials for "Neuralgia"

In order to create insights in the effects of Motor cortex stimulation (MCS) on intractable pain, an open observational study was started in 2003. The aim of this research is to: to determine the clinical effectivity of MCS on pain intensity after 1 month, 1 year and 3 years of stimulation to determine the clinical effectivity of MCS on QoL and daity medication intake after 3 years of MCS

Since its introduction in the 1970s, Paclitaxel has been used as an effective anticancer agent against lung, breast, ovarian, leukopenia and liver cancer. But, Paclitaxel-induced peripheral neuropathy is the major dose-limiting side effect of paclitaxel.Paclitaxel induced peripheral neuropathy most commonly presents as Pain Burning, Tingling ("pins and needles" feeling) or electric/shock-like pain, Hyperalgesia, Allodynia, Increased sensitivity to cold or heat These symptoms are classically seen symmetrically in the distal extremities (glove and stocking distribution). Most adverse effects associated with chemotherapy are ameliorated after cessation of the therapy, but CIPN may persist in the longterm, with 30 % patients having CIPN related symptoms beyond 6 months after completion of chemotherapy7.Understanding the epidemiology of neuropathic pain in breast cancer patients has high clinical and public health significance.

This research study will examine the feasibility of conducting an eight-week yoga intervention for individuals with chronic painful chemotherapy-induced peripheral neuropathy.

Rheumatoid arthritis is a chronic inflammatory disease that mainly affects the joint synovium. Rheumatoid arthritis patients define pain as their major symptom and the most important reason for applying to a healthcare institution. Approximately 70% of rheumatoid arthritis patients state that improvement in their pain compared to other symptoms of the disease is their priority. Pain in rheumatoid arthritis patients is also important as the disease affects approximately 0.5-1% of patients worldwide. Although pain in rheumatoid arthritis patients can be persistent or intermittent, localized or widespread, it has often been associated with fatigue and psychosocial stress. Although nociceptive pain,defined as 'gnawing' or 'aching', is frequently observed in rheumatoid arthritis patients, typical neuropathic pain,such as 'burning' or 'itching', can be observed in some RA patients. It is thought that neuropathic pain may occur as a result of lesions or disease affecting the somatosensorial nervous system. Neuropathic pain can occur with little or no stimulus, and its symptoms are abnormal sensations such as hyperalgesia and allodynia. The diagnosis and treatment of neuropathic pain in rheumatoid arthritis patients is important because neuropathic pain does not decrease with traditional disease-modifying anti-inflammatory drugs used in rheumatoid arthritis and causes a decrease in quality of life. In order to distinguish neuropathic pain from chronic pain, methods based on defining the quality of pain are often used. Some of these methods are; The McGill Pain Questionnaire, PainDETECT, RAPS (Rheumatoid Arthritis Pain Scale), VAS (visual analog scale), AIMS (Arthritis Impact Scale), EQ-5D (European Quality of Life Assessment and Pain Assessment Questionnaire). The diagnosis and treatment of neuropathic pain in rheumatoid arthritis patients is important because neuropathic pain does not decrease with traditional disease-modifying anti-inflammatory drugs used in rheumatoid arthritis and causes a decrease in quality of life.

Observational cohort prospective study with the following of 100 patients of type 1 and type 2 diabetes mellitus in 2 groups each group 50 patients, each group 30 males, and 20 females,35 patients with type 2 diabetes and 15 patients type 1 diabetes all have diabetic peripheral neuropathy, the second group is considered as control.

The most common entrapment neuropathy symptoms, the diagnosis of CTS, is determined by examination findings and by means of the results of electro-diagnostic test. With an increase in disease severity, trap neuropathy, whose symptoms are more pronounced at night, negatively affects the daily life of the person. Deterioration in sleep quality may cause depression and anxiety. Conflicting results have been found in the studies related to these findings. However, no study was found in which daytime sleepiness was evaluated in terms of CTS. The investigators aim in this study is to evaluate the relationship between CTS severity and depression, anxiety, sleep quality and daytime sleepiness.

Pain is the most common component of the morbidity seen in sickle cell disease (SCD), and may be acute or chronic. It is most commonly acute and a result of the hallmark vaso-occlusive episodes of the disease. Many patients however suffer from chronic pain - defined as pain lasting over three months- with neuropathic pain being a component of chronic pain. Neuropathic pain significantly contributes to the chronicity and morbidity of pain in SCD patients, and is an inadequately managed complication. There is a paucity of literature covering this area, and it has never been examined in the Jamaican population. The main objective of this study is to determine the epidemiology of pain among Jamaicans with SCD, and determine the prevalence of chronic and neuropathic pain among these patients. A second objective is to validate, using gold-standard measures, screening tools to determine neuropathic pain among the study population. This cross-sectional study will investigate the prevalence of neuropathic pain and complications in a sample of persons with SCD in Jamaica aged 14 years and older, with a validation sub-study to be conducted on a random 20 percent of the sample. With improved diagnosis of neuropathic pain, clinicians may potentially improve the management of pain in SCD, as clinicians should be able to direct our treatment toward medications and non-pharmacological methods of pain relief that are more specific for neuropathic pain. All data will be de-identified and maintained in a secure database, with access limited to key personnel. There is very minimal risk to participants.

The purpose of this research study is to see if there is a relationship between the tightness of the hamstring muscles (muscles on the back of the thighs), reported sensations related to stretch of the nerves of the lower extremity, and different positions of participants' backs. We will investigate the qualitative differences as provided verbally by participants (sensation felt at maximum knee extension angle) and quantitative differences as provided by surface electromyographic (EMG) measurements of hamstring activity and inclinometer measures of the knee angle.

Dry eye affects millions of people around the world. Some dry eye patients complain of neuropathic eye pain that can affect their quality of life. From August 2016 to June 2017, the QUALVIDON study (NCT03296111), conducted at the Adolphe de Rothschild Foundation Hospital, assessed pain and its impact on quality of life using self-administered questionnaires in a series of dry eye patients. This 2nd study, entitled QUALVIDON2, focuses on the outcome of patients previously included in QUALVIDON.

Persistent pain after breast cancer surgery (PPBCS) affects 25-60% of breast cancer survivors and nerve damage has been implicated as the cause of this neuropathic pain condition. Local anaesthetic blockade of tenderpoints and the intercostobrachial nerve (ICBN) could provide clues to pathophysiological mechanisms as well as aiding diagnosis and treatment of PPBCS but has never been attempted. The aims of this study is to examine clinical effect of ultrasound guided blockades of the ICBN and tenderpoints of pain.
