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.
The para-aortic lymph node involvement in the advanced stage of cervical cancer is a poor prognostic factor for overall survival. Concomitant chemo-radiotherapy has become the standard treatment for advanced cervical cancer. In case of para-aortic lymph node involvement, an extension of radiotherapy fields is recommended. A prospective multicentre study shown that the survival rate of patients with node ≤ 5 mm and which benefited from the expansion of radiotherapy fields was identical to the survival of pN0 patients. However, due to a specific disease, this technique should not be performed in all patients. It is necessary to reliably select patients with retroperitoneal lymph node involvement. For this, it is recommended that prior to the concurrent chemo-radiotherapy, nodal staging surgery with a definitive histological analysis. So we propose to use molecular diagnostic test OSNA (One Step Nucleic Acid Amplification) to improve lymph node metastasis detection sensitivity to achieve ultra-staging compared to conventional histology.
Primary immune deficiencies (PID) are characterized by a failure of the immune system that is not explained by any infectious, neoplastic, or iatrogenic cause. In 2015, more than 300 different inherited rare disorders were described. The occurrence of PID in adult is rare and diagnosis may be supported by the 6 ESID signs for adult. However these warnings signs are based only on expert recommendations and do not include comprehensive symptoms of PIDs. Recurrent infections, more aggressive, are the most common mode of revelation of the PID. Less frequently, autoimmune manifestation, solid tumor, lymphoproliferation tumor, chronic granulomatosis or hemophagocytic lymphohistiocytosis syndrome (HLS) may also revealed a PID. The objective of this study was to evaluate the occurrence of unknown PID in adult admitted in critical care unit and to determinate if the investigation of PID in patients with severe infections or HLS should be routinely performed in MCIU.
Pathophysiology of polymyalgia rheumatica (PMR) is ill defined. This study aims at characterizing immunological abnormalities in PMR patients, and to assess the effects of tocilizumab therapy on this abnormalities.
The primary objective of this study is to compare two groups of gynecologic/urologic/visceral internes in terms of the time required to perform a laparoscopic surgical intervention (nephrectomy) on an animal model (pig). The two groups of internes differ by the type of training they received: (1) Pelvic-Trainer training with robotic assistance versus (2) Pelvic-Trainer training without robotic assistance.
Cryopreservation of ovarian tissue is offered to young girls and women aged under 35 who have to undergo sterilizing gonadotoxic treatment, with the aim of preserving their fertility. The main part of the ovary is preserved, as primordial and primary follicles are resistant to freezing / thawing protocols. In the absence of other techniques (in vivo maturation, injecting isolated ovarian follicles, etc.) autografting this cryopreserved tissue is currently the only technique allowing fertility to be restored. Autograft is possible only if the indication for ovary cryopreservation is a non-neoplastic pathology or a malignant pathology with a low risk of ovarian metastasis. In other cases of neoplastic pathologies, particularly in cases of acute leukemia, tissue cannot as yet be re-used due to the lack of any codified technique for evaluating residual disease (MRD). The team has for two years been developing and validating a technique to look for residual disease in fragments of ovarian cortex in cases of acute leukemia. This technique is based on an original protocol for dissociating ovarian tissue to obtain a population of isolated ovarian cells that may be analyzed by multicolor flow cytometry. The specificity and sensitivity of the technique have been demonstrated in an experimental model. This model consists in using 8 color flow cytometry to look for characterizable leukemia cells added in different dilutions to a population of isolated ovarian cells taken from model ovarian cortex and up to a dilution of 10-5. When the molecular markers were present on diagnosis, they were found by RQ-PCR (Real-Time Quantitative Polymerase Chain Reaction) with the same dilutions. The model tissue came from laparoscopic ovarian drilling in patients with polycystic ovary syndrome. The main objective of this project is to validate techniques that have been previously codified with different populations of leukemia cells that may be characterized. We then aim to adapt and validate this technique to look for MRD using 8 color flow cytometry on cryopreserved fragments of ovarian cortex from leukemia patients that are at risk of metastasis. Secondary objectives will be to implement procedures for oncological qualification of grafts in cases of malignant pathology and to consider the recommendations for using this cryopreserved ovarian tissue through the autograft technique for these indications.
Schizophrenia is a severe psychiatric disorder that affects approximately 1% of the population worldwide. Although pathophysiology of this disease remains unclear, a growing interest is emerging for low-level sensory function, acknowledging that deficits in early stages of sensory processing are related to higher-order cognitive disturbances in schizophrenia. In the field of auditory processing, symptoms as auditory-hallucinations were found correlated with disabilities to discriminate psychoacoustic parameters of sounds.
Epidemiologic Study and Impact Study of a Dialysis Solution Change on the Electrocardiographic Profile of Patient
The objective of this study is to describe the change in the percentage of fat in the lumbar spine.
The aim of the study is to describe the early adaptation of the right ventricle assessed by echocardiography to change of pulmonary circulation secondary to pulmonary transplantation. Secondary objectives include change of haemodynamics measured by transpulmonary thermodilution and evolution of right heart function in terms of primary graft dysfunction grading.
This phase I open label study is conducted to assess the potential pharmacokinetic interaction of Raxone® with midazolam in healthy male volunteers
