Filter by:The broad aim of the study is to implement and evaluate the efficacy of Graded Exposure Treatment (GET Living) to target elevated pain-related fears in children with chronic pain. Pain-related fear is an important psychological factor associated with poor outcomes in children suffering with chronic pain. To examine the efficacy of GET Living in addressing pain-related fears the investigators propose to use a sequential replicated randomized single-case experimental phase design with multiple measures. The specific aims are to 1) evaluate the effectiveness and acceptability of individually tailored GET Living for children with high pain-related fear and functional disability and 2) define anatomical and resting state connectivity patterns in the brains of children and adolescents with complex chronic pain prior to and after participation in GET Living.
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.
This is a pilot study designed to collect preliminary data on safety and efficacy of transcranial direct current stimulation (tDCS) to relieve pain in cancer patients who developed neuropathic pain in the affected area after a surgical intervention, radiation therapy, or chemotherapy to treat the disease.
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.
At Saint-Antoine's hospital, in CETD a multidisciplinary team takes care of patients with chronic pain. Free-drug techniques are available to reduce their consumption of analgesics. This study is to assess the relief obtained by the simultaneous combination of these two techniques: transcutaneous electrical nerve stimulation and hypnosis.
Pain affects up to 30% of the general population. In particular, neuropathic pain (NeP) is caused by lesion or desease affecting peripheral or central somatosensory pathways and affects 7% of the adult population. Despite the availability of evidence based pharmacological and surgical treatment for NeP, about 50% of patients remais symptomatic despite best medical treatment. Some neuropathic pain syndromes are specially refractory. In particular, central NeP is caused by disease or lesion to central structures involves in somatosensory integration of nociceptive information is non-responsive to drugs usually employed in other NeP syndromes. Classical neuromodulatory techniques such as conventional repetitive Transcranial Magnetic Stimulation aiming at the motor of prefrontal cortices are ineffective to relieve pain in this population. Recently new technology advances have made possible non-invasive stimulation of deeper cortical targets. Some of them are activelly involved in the integration of the perception of pain, such as the anterior cingulate cortex or the posterior insula. The aim this study is to treat 90 patients with central pain (post stroke pain, spinal cord lesions after trauma or demyelinizating diseases) under best medical pharmacological treatment in three different conditions: AAC (n= 30 with the H-Coil), Superior Posterior Insula (SPI) n=30 cooled double cone coil double cool coil, and sham(n=30). Each patients will undergo daily stimulation for a week, then weekly stimulations for 3 months (total of 17 sessions). The main study outcome is pain relief at the last stimulation week (visual-analogic scale). Secondary end-points are changes in the McGill Pain Questionnaire, Neuropathic Pain Symptom Inventory, DN4 questionnaire, SF -36, brief pain inventory and cognitive assessment including the trail making test A and B, Strrop color interference test, and subscalles from the CERAD. All patients will undergo quantitative sensory test and measurements of cortical excitability over M1 before and after to treatment.
The objectives of this study are, to test the effectiveness of Valproic Acid (VPA) in the prevention of chronic neuropathic and post-amputation pain, as well as to further define the underlying inflammatory and epigenetic mechanisms that lead to the development of such chronic pain. HYPOTHESES AND QUESTIONS Hypothesis 1: The use of oral valproic acid in combination with regional anesthesia in surgical limb-injury patients will decrease the incidence of chronic nerve injury and post-amputation pain. Goal 1: In a blinded, randomized placebo-controlled, multi-center clinical trial, investigators will determine if oral VPA added to regional anesthesia and standard perioperative management will reduce the incidence of nerve injury and post-amputation pain when compared with regional anesthesia alone. Hypothesis 2: The transition from acute to chronic pain is mediated via epigenetic mechanisms (differential DNA methylation) in genes involved in nociception. Goal 2: Investigators will analyze the DNA methylation patterns of patients with different types of neuropathic and post-amputation pain and determine if they are altered by VPA.
Spinal cord injury neuropathic pain (SCI-NP) is a common problem, and when severe, is one of the most problematic of secondary conditions that is minimally to modestly responsive to currently available treatments. It is usually described as burning or stabbing, and is located at or below the level at which their sensation changes from normal to impaired; persons with no feeling at all in their legs for example can experience pain in the legs. The purpose of this project is to further investigate the use of a novel visual stimulation treatment; a technique that has shown benefit in other populations with chronic pain secondary to deafferentation. To accomplish this, a novel treatment - virtual reality (VR) walking - will be examined. Should this treatment show benefit, a portable, accessible means of treatment will be available for persons with SCI and for whom transportation to health care providers is often difficult.
The study aims to estimate the incidence of herpes zoster (HZ), proportion of postherpetic neuralgia (PHN) and the economic burden and impact on quality of life, in Japanese adults greater than or equal to sixty years of age.
The purpose of this study is to determine if minocycline is effective in the treatment of neuropathic pain. The effect of minocycline will be compared to the effect of placebo and amitriptyline.
