Filter by:According to the WHO, pain is an "unpleasant sensory and emotional experience, linked to existing or potential tissue damage, or described in terms suggestive of such damage". It is a legal obligation to evaluate and take care of it (law of 03/04/2022). However, there are still areas where this is not addressed, particularly in cirrhotic patients (Piano V et al. 2023). The global prevalence of cirrhosis increased by 74.53% between 1990 and 2017 (Liu YB et al, 2022, INSERM France file and Zhai M et al. 2021). In France, the prevalence of cirrhosis is estimated to be 200,000 patients (Cohorte Constances 2017; Serfaty 2019). The causes are varied: toxic (alcohol), viral (hepatitis B, C, HIV), genetic (hemochromatosis, primary biliary cirrhosis) but also iatrogenic or linked to a metabolic syndrome, non-alcoholic fatty liver disease. The first symptoms of cirrhosis are fatigue, loss of appetite and weight, nausea and vomiting, discomfort and abdominal pain. More serious symptoms may appear such as depression, confusion, sleep disturbances, edema of the lower limbs, ascites, severe pruritus or jaundice. All of these symptoms can be the cause of the pain. However, to date, there are no studies in France on the epidemiology of pain in patients with cirrhosis (Piano V et al. 2023, Klinge M, et al, 2018). To evaluate the prevalence of pain in cirrhotic patients hospitalized at the Center Hospitalier de la Dracénie in Draguignan. Patients hospitalized at the Dracénie CH with a diagnosis of cirrhosis in its patients will be identified in the various departments by a referring doctor who will have to contact Dr PIANO. The latter, as investigating doctor, will then be able to select the patients meeting the inclusion criteria of the protocol and the informants of the existence of the research. He will explain the study to them in detail, give them sufficient time for reflection before obtaining their oral agreement and giving them the information-no-opposition letter. The research will require a single consultation lasting between 15 and 45 minutes. During the visit, the patient will be asked whether or not they are experiencing pain.
The goal of this study is to compare pain outcomes achieved by spinal cord stimulation (SCS) using time varying stimulation patterns with pain outcomes achieved by current standard of care SCS.
Fibromyalgia Syndrome (FMS); is a complex syndrome characterized by many symptoms such as chronic widespread pain, fatigue and sleep disorders, cognitive dysfunctions and psychiatric disorders. It has been stated that there is an urgent need for studies examining the clinicimetric and psychometric properties of the pain phenotype criteria in terms of patients receiving the most appropriate treatment, clinicians deciding on the appropriate treatment, and contributing to the research of scientists. Despite all this, no study has yet been found that describes the pain phenotypes in fibromyalgia syndrome and how different types of pain affect patients. The primary aim of this study is to determine the chronic pain phenotypes in individuals with FMS. The secondary aim of this study to determine the inter-rater and intra-rater reliability of the algorithm used in the determination of pain phenotypes and to assessment the clinical effects of different pain phenotypes on individuals with FMS in terms of pain severity, disease severity, quality of life and catastrophe.
The goal of this randomized double blind three way (1:1:1) cross over clinical trial is to evaluate the effectiveness and duration of analgesia of a single infusion of (2R,6R)-HNK 0.5mg/kg compared with ketamine 0.5mg/kg and saline with a 5-week interval between treatments on pain, pain qualities, physical function, pain interference, sleep disturbance and quality of life in subjects with neuropathic pain of the extremities. The questions that this study will address are: 1. What is the analgesic efficacy of (2R,6R)-HNK on pain intensity and pain qualities in patients with chronic (>3 month) neuropathic pain (NP). 2. What will be the effective duration of a single infusion of (2R,6R)-HNK in patients with NP. 3. Will (2R,6R)-HNK reduce pain related effects including interference in daily activities of life, sleep disturbances and change the qualities of pain reported by patients. Participants will receive each of the three study drugs in a random order at 5-week intervals over a 15 week period. The drug will be administered as a 45-minute infusion. Participants will complete quantitative sensory and pain evaluations and complete patient reported pain outcomes prior to receiving the first study drug and at 7, 14 and 21 and 35 days following study drug administration.
The goal of this pilot trial is to test whether scrambler therapy (ST) is an effective treatment for neuropathic pain in patients with corticobasal syndrome (CBS). The main question it aims to answer is: Will ST reduce pain scores by at least 33% at one month in this pilot trial, justifying further multi-center trials? Participants will: - be randomly assigned treatment from either transcutaneous electrical nerve stimulation (TENS) or ST for pain initially (eventually all patients will receive ST). - have superficial electrocardiogram (ECG) electrodes placed on the dermatomes involved with pain - obtain treatment lasting 30-40 minutes or until pain relief is obtained Researchers will compare patient's response to pain relief with TENS and ST to determine if ST is an effective treatment for central neuropathic pain.
Phase I Part 1 (single ascending dose): Double-blind dosing will occur in healthy volunteers in 5 cohorts of 8 subjects each. Six subjects in each cohort will be randomized to receive AFA-281 and 2 subjects will be randomized to receive the matching placebo. At the end of the Part 1 study is to evaluate the safety and tolerability of AFA-281. Following completion of each cohort, bioanalytical analyses will be conducted to evaluate the pharmacokinetic profile. Phase I Part 2 (multiple dose for 14 days): Pending the results from Part 1, healthy volunteers will be administered AFA-281 for 14 consecutive days in 3 cohorts. At scheduled intervals after dosing, and at the end of the cohort's study period to evaluate the safety and tolerability of AFA-281 and the pharmacokinetic profile of AFA-281.
use of dexmedtemodine to augment analgesia in cases of failed back surgery
Comparing efficacy of hyalase and midazolam in median nerve entrapement neuropathy
The aim of this study will be to investigate the effect of an opioid-free anesthesia regimen with a mixture of dexmedetomidine-lidocaine-ketamine in the same syringe versus fentanyl analgesia in elective thyroidectomies. Recovery parameters and nociception levels throughout the operation will be evaluated
The aim of the study is to evaluate the effects of neuropathic pain due to type 2 diabetes on balance and gait. The study is a prospective controlled study. The study is being carried out at the Physical Therapy and Rehabilitation Center Gait Analysis Laboratory Unit in Turkey. Individuals diagnosed with neuropathic pain due to Type 2 Diabetes and individuals with diabetes without neuropathic pain are included in the study by clinical examination and tests by a physician. At the same time, healthy individuals are participating as the control group. There will 3 groups in the study : Group 1: Individuals diagnosed with neuropathic pain due to type 2 diabetes (n=14) Group 2: Individuals with type 2 diabetes but no neuropathic pain (n=14) Group 3: Healthy control group (n=14) Assessments: Individual and clinical characteristics of individuals: age, gender, height, body weight, marital status, education level, duration of complaints, and dominant side. Douleur Neuropathique en 4 questions (DN4) Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Questionnaire Visual Analog Scale (VAS) Gait analysis Static and dynamic balance The data will be analyzed using the statistical program for social sciences (SPSS) version 21.0 (IBM SPSS Statistics for Windows, Armonk, NY: IBM Corp.). The data will be expressed as mean standard deviation (X±SD) and number (n%). The homogeneity of the groups will be evaluated with the Levene Test. Balance, plantar pressure, and walking values between the groups will be compared using the Kruskal Wallis Test. All the statistical analyses will be set a priori at an alpha level of p<0.05.
