Persistent Pain After Reconstruction Following Mastectomy
Breast CancerChronic PainA cross sectional study to determine the prevalence of persistent pain after reconstructive surgery after mastectomy for breast cancer, with a comparative analysis of a cohort treated with mastectomy without reconstruction.
Influence of the Surgical Approach on the Development of a Chronic Pain After Thoracic Surgery
PainPostoperativeThe prevalence of chronic pain after a thoracotomy is around 48 %. This research focuses on the surgical approach. The posterolateral approach is compared to the axillary approach especially in term of development of a chronic pain.
Tracking Outcomes in Pain Patients Using Fitness Devices
Chronic PainBack PainThe investigators are assessing the validity of fitness devices as surrogate measures of chronic pain survey outcomes.
Health-economic Evaulation of Interventional Pain Mangement
Chronic PainTo establish the cost per QALY (Quality Adjusted life Years) gained all patients that are referred to a specialized interventional pain clinic are assessed by Euroqol EQ-5D to measure the health-related quality of life at the first visit and then during the following year. Quality of life is calculated from EQ-5D by using hte TTO-validated UK-value set. With this and calculations of the cost we will be able to calculate the cost per QALY-gained which makes it possible to compare interventional pain managment to other treatments for pain patients.
Characterization of Post-operative Pain Trajectories Over Seven Days and Links With Chronicity
Surgical ProceduresOperative2 moreThe main objective of this study is to establish the postoperative "pain pathways" observed from D1 to D7 in the context of the current management after orthopedic, digestive, obstetrics and gynecology, urology, neurosurgery, vascular and thoracicn surgeries.
Long-term Follow-up After Laparoscopic Inguinal Hernia Repair Using Tisseel for Mesh Fixation
HerniaInguinal2 moreIn hernia repair a mesh is used to close the defect in the abdominal wall. This mesh is either secured with tissue penetrating devices (ex. staples,tacks or sutures) or fibrin glue (Tisseel/Tissucol) or left unfixated. The investigators believe, and previous studies indicate, that the use of fibrin glue greatly reduces the amount of postoperative complications (ex. chronic pain, impaired ejaculation in men or recurrence of the hernia)when compared with the use of tacks or staples. The aim of this study is to compare the recurrence rates and amount of postoperative complications in patients who have had inguinal hernia repair with fibrin glue and in patients who have had inguinal hernia repair with tacks, staples or sutures.
Block REducing Pain After Surgery Trial
Chronic Pain Post-ProceduralThis observational study evaluates difference in chronic pain after six months from surgery between patients who received PECS block and general anesthesia versus general anesthesia alone.
Neuropathic Pain After Lung Surgery
Chronic Neuropathic PainPostoperative5 moreTo understand pain pathophysiology in terms of risk factors and protective mechanisms ranging from molecular pathways to societal impacts.
Polyneuropathy in Diabetes Mellitus Type 2
Diabetes Mellitus Type 2 Without ComplicationPolyneuropathies4 moreThis is a population-based study of type 2 diabetes patients with and without neuropathy recruited from the Danish National Type 2 Diabetes cohort (DD2). Perspective: The study will identify risk factors for developing diabetic polyneuropathy and painful diabetic polyneuropathy and provide information on the underlying mechanisms, which will hopefully contribute to significant improvements in the treatment and prevention of diabetic polyneuropathy in future.
Prescription Opioid Misuse Assessment
Chronic PainChronic pain is a worldwide health problem due to its high prevalence and its difficult management with a significant impact on quality of life. Pain and addiction co-occur frequently. Indeed, the prevalence of addiction in patients with chronic non-cancer pain may affect from 0% to 50% of patients (Højsted et al 2010). This large variability in the estimation of addiction prevalence in chronic non-cancer pain patients is at least partly due to a lack of standardization of the selected patients from the clinical or therapeutic point of view and the lack of consensus in the use of a specific evaluation tool or gold standard. Indeed, several tools are currently available at the international level with varying efficiencies and precisions (Chou et al 2009, Turk, Swanson, and Gatchel 2008, Højsted and Sjøgren 2007). In France, no data are available on the prevalence of analgesic opioid misuse in chronic non-cancer pain patients, due to the lack clinical studies and validated tools in French.
