There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Endometriosis is defined as the presence of endometriotic tissue outside the uterus. Its pathophysiology is still misunderstood today, but more and more work on this pathology are published. The clinical presentation is generally characterized by the existence of cyclical pelvic pain, with dysmenorrhea, dyspareunia, dysuria, dyschezia. But, there are a wide variety of symptoms, with different painful sites and different types of pain. The estimated prevalence of endometriosis is about 10% in women. But the impact of this disease on quality of life and its economic impact is estimated considerable. In a US study, the direct costs associated with endometriosis were estimated at US $ 2.801 per woman. Some studies have focused also to quantify work absenteeism associated with endometriosis. The etiology of endometriosis is based on the migration of endometrial fragments reaching the pelvis via the tubes and establishing themselves on other sites, thus creating non cyclical uterine pain. Catamenial pace of pain is suggestive of the diagnosis, but with time, the pain tends to be chronic rather than cyclical. The standard diagnosis is based on visualization and histological examination of the lesions. The wide variety of symptoms of endometriosis often leads to wandering and medical diagnostic delay. A better understanding of this disease by the medical community would allow better management of these patients. Currently, endometriosis remains a misunderstood disease by rheumatologists. However, the initial presentation may mimic rheumatologic symptoms; thus, rheumatologists may face this disease. The purpose of this study was to determine the prevalence and characteristics of manifestations of endometriosis in a cohort of patients with a recent diagnosis of endometriosis established. Secondly, it may well be possible to establish a list of symptoms and signs suggestive of endometriosis for the rheumatologist, allowing to contact a specialized consultant gynecologist some patients "by mistake" in rheumatology.
Urinary measure of 5-hydroxyindolacetic acid (5HIAA) is an important marker for the diagnosis and follow-up of patients with small-intestine neuroendocrine tumors. Although this marker has good specificity, its sensitivity is moderate and its dosage is constraining, since it requires urine collection over 2-3 days and specific diet. Preliminary data suggested that overnight 5HIAA value may be representative of 24-hour 5HIAA value, and that plasma 5HIAA dosage could be a valuable alternative to urine 5HIAA dosage. The main objective of this study is to compare sensitivity and specificity of overnight 5HIAA value, 24-hour 5HIAA value and plasma 5HIAA value, in patients with small-intestine neuroendocrine tumors.
Breast MRI is increasingly important in breast screening imaging. It is currently based on dynamic sequences after contrast injection whose temporal resolution must be less than 90 seconds with dynamic acquisitions at different times. These curves profiles are designed to differentiate benign from malignant lesions. Recently, Mann et al, (2014) showed that increasing the temporal resolution of dynamic acquisitions; lesion enhancement curves over time were more accurate than the curves usually performed. It seems necessary to work on sequences having better temporal resolution without compromising however spatial resolution.
Specific treatments for angiotensin-converting-enzyme inhibitor (ACE-I) and angiotensin-receptor-blocker (ARB)-induced angioedema exist. Early access to these treatments is challenging because they are expensive and have short shelf lives making it illusory that all emergency department (ED) stock them. The aim of this retrospective study was to define, for each patient with a confirmed ACE-I or ARB-induced angioedema, at which step of the care, the specific treatment was administered. The second objective was to analyse the availability of these treatment in the area around Lyon, France and the factors that may influence it.
Transversal multicentric French study on the microbiota in patients with Crohn's disease and their first degree healthy relatives The primary objective is the comparison of microbiota between patients with CD, healthy controls non genetically linked and first degree healthy relatives of patients with CD.
Chronic postsurgical pain (CPSP) is defined by pain persisting longer than 2 months after surgery (1). Its incidence varies from 10 to 50 % in the literature (2). A high proportion of CPSP is neuropathic (CPSNP) (4). Postoperative pain is traditionally classified as nociceptive pain and the more intense is this pain on a numeric pain scale (NPS), higher are the risks of pain chronicization and the duration of the severe pain is longer (5,6). However, acute neuropathic pain (ANP) can be present in the postoperative setting. However, data on the prevalence of ANP immediately after surgery are scarce and no screening tool has been validated so far in this setting. Therefore, the first objective of this multicenter observational study is to prospectively describe the incidence of APSNP in a large population using the DN4 questionnaire. The second objective of our study is to confirm the hypothetic link between APSNP and CPSNP at 1 and 2 months after surgery in a large population. It is hypothesized that the systematic use of the DN4 questionnaire in postoperative could help detect patients at risk of CPSNP.
Comparison of two techniques of renal pre-transplant infusion on the evolution of renal function in the recipient: multicentre randomized trial
Total replacement of hip joint is one of the most important medical innovations of the twentieth century. More than 100,000 hip replacements are being laid each year in France. Improved fixation, reduced wear rates and reduced implant dislocation rates remain subjects of continuous improvement. Hip implants cemented and cementless are part of therapeutic arsenal of orthopedic surgeons for joint replacement of the defective hip. The anchor and friction torque are both essential to the survival of hip implants. Therefore acetabular implants without cement with ceramic insert or polyethylene in a metalback or full polyethylene coated with titanium grains without metalback are proposed, but they have their own complications (Squeaking, fractures, recovery difficulties, difficult radiographic analysis, high cost for ceramics, primary stability defects, instability of the instrument set, Titanium residues in absence of metalback. An alternative to these implants may be an acetabular component without cement with polyethylene insert with an end metalback to increase both polyethylene thickness and size of the head in order to expect a low complication rate with important longevity for a lower cost. This study was conducted to ensure the safety and effectiveness of the acetabular implant "POLYMAX"
Given preliminary data in animal (proprietary data) have shown that XXS (a mixture of natural polyphenolic extracts of edible plants) has a significant and favourable effect on oxidative stress notably with a decrease in certain markers of oxidative stress and on plasma lipid parameters, the investigator proposes to study the effect of 6 months of treatment with XXS in a controlled study against placebo in a population of persons presenting a lipid profile at the upper limit of normal.
The investigators will investigate which patients' characteristics are associated with caregivers burden and its evolution for outpatients visiting a memory clinic, in particular how functional autonomy, behavioral and psychological symptoms as well as patients comorbidities can influence caregiver burden. The study will be conducted among outpatients with progressive cognitive complaint followed in a Memory Clinic and their primary caregiver. The investigators hypothesis that caregivers experience a higher burden due to disease symptoms such as impairment of functional autonomy, behavioral and cognitive impairment, whatever the aetiology of the cognitive decline.
