Filter by:Spinal cord stimulation (SCS) is a medical device inserted beside the spine to treat nerve pain. When the device becomes infected (which happens 4 % of the time) it needs to be taken out and put back in again at a later date. So far we are unsure of how much this process costs. I am going to analyse data collected on a database of all devices taken out due to infection and calculate an average cost of taking them out, the intermediate care and putting them back in again in our hospital only. This will enable us to understand how much this process costs and if there are any methods of reducing the chance of infection in the future; we will be able to work out how much the NHS should pay for these products based on this data. This will be done in Guys and St Thomas's from a database in the chronic pain research department in patients who had their device taken out due to infection. It will take 6 months and will all be retrospective. Additional details may be collected from patients electronic records where needed. These will be collected by a member of the direct care team and pseudonymised prior to adding to the research data set.
The main hypothesis of this study is that the alteration of the reward circuitry underlying the motivational deficit in chronic pain patients compared to healthy subjects results in a decrease in the capacity for reward learning. The fMRI studies have shown that this type of learning depends on the dopaminergic system innervating key regions of the reward system.
The overarching aim of this study is to investigate the contribution of peripheral afferent input to spontaneous and evoked central neuropathic pain after a spinal cord lesion or disease.
The main purposes of this study are to (1) measure the effect of CBD on pain symptoms, pain intensity, pain unpleasantness, and skin sensitivity to hot and cold temperature; and (2) measure the effect of CBD on brain electrical activity with electroencephalography (EEG).
Endometriosis is a chronic, inflammatory disease where endometrium-like tissue is present outside the uterus. Nerve cells in the proximity of this tissue express cytokine receptors causing a signaling cascade. This results in active cross-talk between endometriosis and nerves, causing pelvic pain. Other symptoms associated with endometriosis are cyclical such as dysmenorrhea and dysuria, and non-cyclical such as dyspareunia. Despite adequate disease management, women can still experience endometriosis-related pain. A recent development proven to be efficient in treatment of neuropathic pain, is Spinal Cord Stimulation (SCS). It is also thought to be effective in the treatment of visceral pain. Several studies found Spinal Cord Stimulation (SCS) to be effective in the reduction of endometriosis-related pelvic pain. However, scientific evidence on the efficacy of SCS in visceral pain is limited.
The investigators aim from this study, to determine the safety and efficacy of pulsed radiofrequency in the management of pudendal neuralgia, compared to current a standard intervention, which is corticosteroid injection for PN, as part of multidisciplinary pain management.
Head and neck cancers are a source of complications and after-effects related to the disease and treatment. These cancers and their treatment alter the quality of life of patients and generate pain with physical and psychological components. Chronic pain affects 36% of patients at 6 months and 30% after this period. These pains are responsible for the consumption of level II and III analgesics in 53% of these patients. At the same time, after the end of treatment, nearly a quarter of patients continued to smoke and half still consumed alcohol at least twice a week. The hypothesis of this research is to investigate the correlation between pain and the continuation of addictions, the occurrence of depressive states, asthenia and the alteration of the patients' global quality of life. The investigators propose a two-center prospective cohort study to evaluate this hypothesis at 6 months after radiotherapy treatment. This study is planned to include 120 patients with a first head and neck cancer whit radiotherapy as part of their treatment sequence. The expected duration of inclusion is 18 months. The identification of factors affecting survival, quality of life and patient compliance is essential to determine appropriate management, particularly by creating appropriate therapeutic education programs.
The aim of this study is to assess the feasibility of deep brain stimulation for refractory trigeminal neuralgia due to a pontine demyelinating lesion, as is usually seen in the context of multiple sclerosis. These patients usually have severe intractable facial pain and current medical and surgical options generally fail to achieve long lasting pain relief. Hoping to improve pain control in this population, the investigators of this trial propose a novel technique consisting of implanting a deep brain stimulation lead within the pontine lesion to modulate the generation of pain signals.
This research will provide a better understanding of the interaction of chronic neuropathic pain and its interaction with the mental state. In addition, he will compare the results of simple classical physiotherapy intervention with cognitive physiotherapy intervention in chronic neuropathic pain. Finally, it will highlight the usefulness of integrating elements of cognitive-behavioral therapy in physiotherapy intervention to achieve a comprehensive anthropocentric therapy.
In this study, patients scheduled to undergo total knee arthroplasty (TKA) will be screened through a survey for patients without central sensitivity and patients with neuropathic pain as preoperative evaluation. It is designed to evaluate the effectiveness of pregabalin by dividing patient groups according to non central sensitization and neuropathic pain.
