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.
Macular hole is an infrequent retinal pathology (2 to 4/1000) which most often affects people aged over 60, and twice common in women than men. The vast majority of cases are idiopathic. Without treatment, the macular hole evolves through a series of stages until the extension of the diameter (up to 500 microns and higher values). With a fully developed macular hole, patients complain of metamorphopsia and decreased visual acuity. This pathology has clearly benefited from advances in microsurgery and better understanding of its pathophysiology. Macular hole treatment has evolved to include small-gauge pars plana vitrectomy with or without internal limiting membrane (ILM) peeling and placement of intraocular gas tamponade. The postoperative closure rate is close to 80%, but strongly depends on the initial characteristics of the hole, its diameter remaining the main prognostic factor. Thus for macular holes <400 microns, the closure rate is close to 92% dropping to 56% for macular holes above 400 microns. In case of surgical failure, one or more reoperations can be proposed, but with a lower closure rate. The quest for a surgical technique presenting a greater success rate is a common goal to all retinologists. Here the investigators propose a new surgical technique, derived from the FLAP method, and consisting of an inner limiting membrane transposition. The objective of this study is to evaluate the feasibility of a new surgical technique for the treatment of macular holes already operated but without macular hole closure, allowing these patients a new therapeutic alternative. The success of this technique will be confirmed by detecting postoperatively the presence of the transposed internal limiting membrane into the foveal region.
The aim of this study is to prospectively evaluate the tolerance and efficiency of a new technique of preoperative selective portal vein embolization (PVE) in patients requiring major hepatic resection.
When the upper chambers of a person's heart receive or generate irregular electrical signals, it causes abnormal rhythm in the heartbeat. This is called atrial fibrillation. Atrial fibrillation goes along with blood clots that may cause mainly strokes and less often other diseases, such as a heart attack. Some patients with atrial fibrillation have other heart disease, such as heart valves that may need to be replaced using catheters. Often doctors give patients drugs that reduce those blood clots. These are either vitamin K antagonist (VKA) or direct anticoagulants, such as edoxaban. In these patients, it is unclear which of the drugs is better for reducing stroke without increasing severe bleedings.
Colon cancer is a very common cancer. Prognosis and adjuvant treatment depend on the pathological results. Histoprognostic new factors have recently been published by several authors, but their validity is still debated.
In high-risk patients, it is now recommended to guide the intraoperative volume replacement via the stroke volume. Today, the most commonly used technique for estimating the stroke volume is the transpulmonary thermodilution and the arterial waveform analysis in the radial artery by PICCO®. This technique has the disadvantage of being invasive and increasing the time dedicated to anesthesia during the surgery. The future is the non-invasive monitoring of stroke volume. Thus, Edwards Life Science has developed a continuous monitoring technology and non-invasive arterial pressure, cardiac output and stroke volume using a digital sensor (ClearSight®). This continuous monitoring of blood pressure was validated in cardiothoracic surgery but studies about monitoring cardiac output or stroke volume are inconclusive and contradictory. The objective of this study is to compare the use of non-invasive monitoring of stroke volume by ClearSight® with the transpulmonary thermodilution and the arterial waveform analysis in radial artery by PICCO® in abdominal major surgery.
The purpose of this study is to collect additional safety and efficacy data for the combination of ribociclib + letrozole in men and pre/postmenopausal women with HR+HER2- advanced breast cancer and no prior hormonal treatment for advanced disease..
The purpose of this study is on one hand to verify the measurement conformity of the IRAP dosage and on the other hand to obtain normal values of the blood IRAP concentration on healthy volunteers.
The purpose of the study is to demonstrate that continuous apomorphine treatment during the night compared with placebo improves sleep quality in insomniac patient with Parkinson's disease.
The axillary brachial plexus block is a technique of locoregional anesthesia indicated in the distal upper limb surgery : hand, forearm, the lower third of the arm including the elbow. The anesthesia of the posterior and the medial side of the arm requires a selective block of the medial brachial cutaneous nerve and the intercostobrachial nerve, for example to improve the tolerance of the inflatable tourniquet used by the surgeons. There are two techniques to achieve this block : the blind technique (without ultrasound) and the ultrasound-guided technique. At the moment, there are no studies which compare these two techniques. So, the purpose of this study is to determine the effectiveness of ultrasound-guided technique compared to blind technique in medial brachial cutaneous nerve block and intercostobrachial nerve block, in the axilla.
The prognostic of burn patients has improved over the last decades. Early excision of full thickness burns is thought to be one of the key factors which have led to prognostic improvement. Best timing for burn excision remain uncertain, however. In this multicenter observational study, we aim at exploring the impact of timing of surgery on outcome in severely ill burn patients using a propensity analysis.
