Serum Potassium as a Predictor of Clinical Outcomes in an Older Patient Cohort With Chronic Postsurgical...
PotassiumDecreased Level2 morePerioperative serum potassium in patients over 65 impacts recovery, quality of life and physical functioning. While perioperative serum potassium is an important preoperative risk factor for poor surgical outcomes in older adults, the relationship between perioperative serum potassium and postsurgical pain in this population has not been investigated. The investigators hypothesized that preoperative serum potassium would be associated with greater odds of postsurgical chronic pain.
Chronic Pain, Life Style Factors and Quality of Life
Chronic PainChronic pain, life style factors and quality of life (KROKIETA) is a multicenter study that aims to analyze life style factors, socioeconomic and psychometric properties, metabolic problems, drug use, quality of life and biochemical variables in chronic non-cancer pain patients. The life style factors will be compared to those of normal population. At baseline, the study patients fill in questionnaires (A-E), the patients´ weight, length, waist and blood pressure are measured, pain-related factors are recorded and blood samples taken. Changes in the quality of life of the study patients will be evaluated by questionnaires during follow-up at 2 years and 5 years.
Predisposition to Persistent Pain After Orthopaedic Surgery: Genetic Aspects
Chronic PainThe study purpose is to examine polymorphism of genes associated to post-operative persistent pain and to verify the possible association between genotype phenotype and ADRB2 polymorphism in orthopaedic surgery. The primary aim is to evaluate the expression of ADBR2 in VAS>4 patients and to compare it to those with VAS<4.
Chronic Complaints After Small Umbilical Hernia Repair
Chronic PainVentral HerniaThere are only little data on the risk of chronic complaints (pain and discomfort) following open non-mesh sutured repairs of small umbilical or epigastric hernias. Our primary and secondary endpoints were long-term pain and discomfort at rest, respectively and thirdly recurrence. The setup was a retrospective two-centre study including patients ≥18 years undergoing primary elective open non-mesh sutured umbilical or epigastric hernia repairs. The survey included questions on suspicion of recurrence, reoperation for recurrence (if yes patients were examined by a consultant in patients home), pain, discomfort, work, and leisure activities. We analysed 295 consecutive patients through a non-validated structured questionnaire.
Chronic Pain After Shoulder Arthroplasty
Chronic PainChronic pain is relatively common after different types of surgery. The investigators intend to study prevalence, characteristics and risk factors of chronic pain after shoulder arthroplasty, focusing on neuropathic pain characteristics, and risk factors such as preoperative pain, severe acute postoperative pain, age, gender, and pain elsewhere.
Transition From Acute to Chronic Pain After Inguinal Hernia, Hysterectomy and Thoracotomy: Analysis...
Chronic Postoperative PainThe treatment of postoperative pain continues to be inadequate in the investigators practice setting. Inadequate pain treatment not only contributes to postoperative complications in the short term but can also be a factor that favors the development of chronic postoperative pain and diminishes long-term quality of life. Risk factors that can lead to a transition to chronic pain need to be analyzed.
Susceptibility to Chronic Post-Traumatic Extremity Pain
Chronic PainThe association between the COMT haplotypes and the presence or absence of CPSP or CRPS will be assessed stratifying the patients based on the individual categories of trauma or elective surgery.
The Application of Performance Improvement Principles to the Patient Throughput Process in an Adult...
Chronic PainThis study is undertaken to assess and improve the existing patient flow, or so-called throughput process, in an adult outpatient pain treatment clinic.
Multiple Areas of Pain (MAP)
Chronic PainThis study will collect pain-related information from chronic pain patients to gain an understanding of the prevalence of multi-site pain, and how it affects health outcomes like function, quality of life, depression, and anxiety.
Observational Study of the Analgesic Effect of Treatment With rTMS in Patients With Chronic Neuropathic...
Chronic PainFor ten years, rTMS, repetitive transcranial magnetic stimulation of the motor cortex, has found its place in the treatment of drug-resistant neuropathic pain. Patients relieved by some sessions may thereafter receive a chronic invasive stimulation via electrodes implanted through a neurosurgical procedure. This is common practice at the University Hospital of Caen and in different CHU with the proper equipment rTMS. It seems permissible to provide in our center only a non-invasive technique for patients challenged with brain surgery, since according to the various meta-analyzes the analgesic efficacy of rTMS seems to be correlated to the repetition of sessions. Assessment centers and the treatment of pain allow a multidimensional assessment, bio-psycho-social of patients in order to optimize their management and experience efficiently analgesics first- and second-line. We propose a study evaluating the analgesic efficacy of rTMS, in relevant stimulation parameters reproduced according to a literature review, during 3 months after 5 active sessions separated by one week apart, in 15 patients with neuropathic pain chronic refractory to treatment of first and second line, followed by multidisciplinary center specializing in chronic pain Lower Normandy. The quality of life will also be assessed by validated scales, and the results will be compared to the literature data.
