Filter by:Over the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with chronic pain disorders due to traumatic or post-operative peripheral neuropathy. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic pain due to traumatic or post-operative peripheral neuropathy.
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 observational study is to learn about sodium channel (Nav) mutations in patients with the Anterior Cutaneous Nerve Entrapment Syndrome (ACNES). This study will give more insight into the pathophysiology of ACNES, which is still largely unknown. The primary objective is to determine if there are mutations of Nav1.7 and Nav1.8 in patients with ACNES. Therefore, one blood sample will be drawn, in which the mutations will be analyzed.
This study relies on the use of a smartphone application (SOMA) that the investigators developed for tracking daily mood, pain, and activity status in acute pain, chronic pain, and healthy controls over four months.The primary goal of the study is to use fluctuations in daily self-reported symptoms to identify computational predictors of acute-chronic pain transition, pain recovery, and/or chronic pain maintenance or flareups. The general study will include anyone with current acute or chronic pain, while a smaller sub-study will use a subset of patients from the chronic pain group who have been diagnosed with chronic low back pain, failed back surgery syndrome, or fibromyalgia. These sub-study participants will first take part in one in-person EEG testing session while completing simple interoception and reinforcement learning tasks and then begin daily use of the SOMA app. Electrophysiologic and behavioral data from the EEG testing session will be used to determine predictors of treatment response in the sub-study.
This is a prospective cohort study to estimate prevalence of chronic pain after cardiothoracic surgery
ACNES is a neuropathic pain condition of the abdominal wall. It is a clinical diagnosis based on patient's history and physical examination. No diagnostic test is available to confirm the diagnosis. This pilot study will determine if skin biopsies can be used as diagnostic test. Two 3mm biopsies will be taken and used to count the small nerve fibres in the skin. The number of small nerve fibres of the painful skin will be compared to non-painful skin. Skin biopsy and small fibre nerve count is already used as diagnostic test in patients with small-fibre neuropathy. The investigators hypothesize that patients with ACNES will have a reduced number of small nerve fibres in the affected skin, compared to the non-affected skin.
This study will evaluate a new form of non-invasive deep brain therapy for individuals with generalized chronic pain. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The trial will evaluate brain target engagement using magnetic resonance imaging and CVAS and PROMIS numerical rating scales of pain.
The investigators propose to conduct a dose-escalation trial of an FDA-approved antiepileptic drug, lacosamide, added to opioid therapy in patients with chronic abdominal pain from chronic pancreatitis (CP). This pilot trial will test the feasibility of the study design and provide reassurance regarding the tolerability and safety of lacosamide used concomitantly with opioids in this patient population to reduce the condition known clinically as opioid-induced hyperalgesia (OIH).
This study will be held on patients with failed back surgery syndrome, the investigators are comparing prolotherapy and steroids injections in caudal epidural space to relieve the pain
The aim of this retrospective study is to determine the factors affecting the development of chronic pain in patients with thoracotomy in the Thoracic Surgery Operating Rooms of İbn-i Sina Hospital. By identifying these factors, it is aimed to apply the necessary treatments to prevent the development of chronic pain and to improve patient outcomes.
