Active clinical trials for "Neuralgia"

Pain is one of the most common symptoms associated with cancer. The approach to pain management compresses routine pain assessments, utilizes both pharmacologic and nonpharmacologic interventions, and requires ongoing reevaluation of the patient. Cancer pain can be well controlled in the vast majority of patients if the algorithms of pain control are systematically applied, carefully monitored, and tailored to the needs of the individual patient.This study is aimed to assess the current pain managements in upper gastrointestinal cancer patients in Taiwan. The effects of neuropathic pain and depression on the enrolled patients would also be assessed.

The BTP (Breakthrough pain)was defined as "a transient exacerbation of pain that occurs either spontaneously, or in relation to a specific predictable or unpredictable trigger, despite relatively stable and adequately controlled background pain". The BTP is a common clinical features in patients with cancer pain (BTcP: breakthrough cancer pain). The prevalence of BTcP is equal to 56%. Currently, the investigators tend to recognize the idiopathic/spontaneous or accident BTcP in the three sub-types: voluntary, non- voluntary and procedural. The diagnosis of BTCP is not always easy because in the cancer patient is normal to observe changes in the intensity of pain during the day, so it is necessary to differentiate slight fluctuations from the presence of real episodes of BTCP, for which is necessary to use a rescue treatment adjusted. In the study will be proposed the use of a diagnostic algorithm, present in the literature, to perform the diagnosis of BTCP. In the presence of BTCP, is important both a correct controlled background pain with major opioids, which can reduce the number and the intensity of the painful episodes, both implement an adjunctive therapy, called "rescue", to be administered at the time which takes over the painful episode using, in this case, an opioid greater.

The role of oxidative stress in the development of oxaliplatin-induced peripheral neuropathy has been previously described in mice and in neuronal cell cultures (Massicot 2013); clinical manifestations and pathophysiological mechanisms potentially involved have also been described in humans (Andreas 2007) (Attal 2009). The investigators team plans to conduct a translational clinicobiological research to explain the nature of the biochemical and molecular mechanisms of the development of oxaliplatin-induced painful neuropathy. To perform this project, the investigators propose to realize a pilot study in patients newly treated with oxaliplatin. This will be conducted in the oncology department of Paris Saint Joseph Hospital from May 2014 until the inclusion of 20 patients. The main objective of this pilot study is to evaluate the occurrence of acute and chronic neuropathic pain occurring in patients newly treated with oxaliplatin. The characterization of this pain is based on validated tests (Cruccu 2010). Moreover, the biochemical changes related to oxidative stress and those related to cellular lipid composition are characterized in these patients.

This study aims for a better understanding of the pathophysiological mechanisms of the complex regional pain syndrome (CRPS). This will be done by testing the quantitative sensory testing, the remote ischemic conditioning, the conditioned pain modulation (CPM) and the analysis of the heart-rate variability in patients with CRPS and a control-group. We hypothesize decreased conditioned pain modulation, less effects of remote ischemic conditioning and an affection of the heart-rate variability in patients with CPRS.

This is a prospective clinical study to assess the performance of the prosthesis according to a composite success criterion. The clinical and functional results and the patient's quality of life up to 24 months of follow-up will also be recorded. Granvia-c is a device NOT FDA-approved and NOT under investigation in the USA.

High doses of gabapentin are associated with pancreatic acinar cell tumors in rats, but there has been no post marketing pancreatic carcinogenicity signal with gabapentin as reported by spontaneous reports in the Adverse Events Reporting System or in the published literature. In a published case-control screening study of the association of gabapentin with 55 cancers, the only cancer that met the screening criteria for possibly increased cancer risk with gabapentin exposure was renal (including renal pelvis) cancer. This association was judged to be likely due to or substantially accentuated by confounding by cigarette smoking, hypertension, and lifestyle (Cancer Causes Control 2009;20:1821-1835). The primary objective of this study is to determine whether exposure to gabapentin is associated with an increased risk of developing pancreatic cancer or renal cancer in the United Kingdom (UK) General Practice Research Database (GPRD). Almost all members of the UK population are registered with a General Practice, which centralizes the medical information not only from the general practitioners themselves but also from specialist referrals and hospital attendances. Over 487 General Practices contribute data to the GPRD. The study cohort from which cases and controls are drawn is all subjects in the GPRD 1993-2008. Gabapentin was approved in the UK in May 1993. Entry into the study cohort begins Jan 1, 1993 for all those who are registered in GPRD before that time, and at the time of registration if later than Jan 1, 1993. Patients with a first diagnosis of the respective cancer 1995-2008 are risk set matched with up to 10 controls within the same General Practice for age at cohort entry (within two years), sex, and year of entry into the study cohort (within one year). For cases, the index date is the date of first diagnosis of the respective cancer. The index date for controls is set as the date at which the follow-up time from cohort entry is the same as the case. The index date is chosen so as to give the control equal follow-up time to that of the case for ascertainment of use of gabapentin. Cases and controls will be required to have at least 2 years of follow-up in the study cohort before their index date. Data on gabapentin prescriptions are obtained for cases and controls from study cohort entry to the index date. Crude and adjusted odds ratios and 95% confidence intervals (CI) will be produced from conditional logistic regression models, with additional analyses evaluating for latency and dose-response. For pancreatic cancer, covariates are smoking, body mass index, diabetes, epilepsy, neuropathic pain, and chronic pancreatitis. For renal cancer, covariates are smoking, body mass index, diabetes, hypertension, diuretic use, epilepsy, and neuropathic pain.

Clinical study with Lyrica (pregabalin) in patients suffering from epilepsy. This drug is used as adjunctive therapy with one or more antiepileptics. Lyrica has potential to reduce seizure frequency.

This study is being conducted as a regulatory requirement post initial marketing authorization. This is primarily a safety study. This was an open label study and patients were enrolled once the decision to prescribe the medication was made by the Investigator.

The objective of this study is to evaluate extent, location, and perception of paresthesia as a function of anode/cathode configuration.

Trigeminal neuralgia or tic douloureux is severe, often debilitating, facial pain that significantly impairs the patient's quality of life and health. Stereotactic radiosurgery has been shown to provide pain relief in majority of patients treated. However, a common side effect of radiosurgery is facial numbness. To better understand how radiosurgery can bring about pain relief and facial numbness, we are conducting a study in which brain MRI scans will be done following stereotactic radiosurgery to learn if there are any changes in the MRI scans that correlate with symptoms.
