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 aim of this study is to evaluate the correlation of retinal nerve fiber layer (RNFL) thickness measured using spectral domain optical coherence tomography (SD-OCT) and scanning laser polarimetry (SLP) in uveitic eyes compared to healthy eyes. A descriptive, observational, prospective, consecutive, cross-sectional, controlled, mono-center case series was conducted from May to October 2015. Clinical characteristics, best-corrected visual acuity, intra-ocular pressure, RNFL thickness measurement with SD-OCT and SLP using GDx variable corneal compensation (GDx VCC) were performed for each patient. An evaluation of anterior chamber inflammation with laser flare cell meter was also carried out. Correlations between SD-OCT and GDx VCC RNFL measurement were evaluated by linear regression analysis.
The aim of this prospective study was to assess the effect of patient positioning on the ultrasound assessment of gastric contents.
This prospective observational study aims to assess whether ultrasound assessment of gastric content may be useful for the monitoring of the gastric residual content in critically ill patients
In France, during surgery, only 4% of parents are present at induction, most often for children with disabilities with iterative interventions. Some studies have shown that the presence of parents during induction decreases the anxiety of children, while others do not. Their conclusions all advocate preparing parents for this presence in the operating room in an accompanying course.
1. Background The results obtained in clinical research led to a new paradigm for the treatment of patients affected with multiple sclerosis (MS): "no evidence of disease activity". This means having each patient monitored with high quality imaging. To this purpose, researchers have developed segmentation algorithms for automated reading of MRIs, facilitating longitudinal comparisons, and allowing an accurate assessment of the number and the volume of focal lesions. We have thus a powerful strategic biomarker for the treatment of MS. Due to the relevance of comparing over time the evolution of lesions (lesion load) and brain atrophy, the French Society of Neuroradiology edited standardized national recommendations. The MS French Observatory (OFSEP) has adopted these recommendations, in order to harmonize exams for all patients all over the country. At an international level as well, MRI have been put at the heart of the therapeutic strategy. Therefore, we need now to create the conditions able to implement, collect and analyze imaging data according to these recommendations. This is the meaning of the MUSIC project, which aims to develop and assess a standardized monitoring MRI control tool for therapeutic decision. CADIMS is this tool. It is based on an integration of several segmentation algorithms developed by INRIA and an image viewer developed by b<>com and included in a regional images-sharing server ETIAM Nexus. This tool is a help showing segmented brain T2 lesions, gadolinium-enhanced T1 lesions and news T2 lesions appeared from the previous MRI exam, in a multicenter clinical context. 2. Objective To evaluate the accuracy of MS lesions detection on cerebral MRI by comparing the CADIMS tool to the expert consensus.
To assess the evolution of biological markers of mesenteric ischemia during ultratrail.
Multiple sclerosis causes demyelinating lesions, which can induce multiple symptoms. If motor disorders are the most visible disability, urinary disorders are frequent, with prevalence from 32 to 86%. The first ones are due to pyramidal, cerebellar or proprioceptive lesions. The seconds are due to specific lesion in inhibitor/activator encephalic centers, or interruption on medullary conduction. It seems to be evident that walk and urinary disorders are link, because of similar anatomic ways and control process. Effect of bladder filling is well known on motoneuronal excitability. The effect of bladder filling on walk stay unknown, while medullary integration of these two functions is very close, in medullary cone. Primary aim is to assess the effect of need to void on walk speed in multiple sclerosis with lower urinary tract symptoms. Secondary aim is to identify clinical or urodynamic factor link with major walk impairment when patients need to void. Patient with multiple sclerosis over 18 years old, consulting for lower urinary tract symptoms in a tertiary center are included. History and treatment, high, weigh, symptoms severity by USP score, cognitive impairment by MMSE score and last urodynamic data are recorded. Patient are asked to drink water until they feel a strong need to void, for which they would go to urinate at home. Walk tests are realized in a specific place, with calm and no passage. A chair is placed at each end of the path. Toilets are just next to the hall where they realize the tests. A 10 Meters Walk Test is done during this condition, 3 times (only the intermediate 6 meters are recorded). They can take 30 seconds of rest between each try if necessary. One Timed up and go is done. Patient can use their habitual walking device. Speed walk asking is comfortable for the two test. Next, patient can urinate. 3 post void residual volume with portable echography are done, and the higher is recorded. Patient achieve the same walk tests after urinate, in the same order. They must use the same walking device. Primary outcome is mean gait recorded for 10 meters walk test. Secondary outcome is time for timed up and go test. Individual variability between the 3 10MWT in the two conditions will be study. Influence of age, EDSS, severity of symptoms, MMSE, detrusor overactivity on speed impairment will be study in secondary analysis.
Difficult orotracheal intubation carries a risk of hemodynamic collapse, neurological sequelae secondary to cerebral anoxia or death. Anesthetic scores and predictive indices are used to predict difficulties and avoid complications for usual tracheal intubation. However, existing indices are not adapted to selective bronchial intubations. The aim of the study is to determine the incidence of unexpected difficult SBI using conventional screening tests. It is a prospective descriptive epidemiological monocentric study comparing two groups of patients (selective vs. non selective intubations).
Reversible cerebral vasoconstriction syndrome (RCVS) is a clinico radiological entity characterized by severe headaches (associated or not with neurological complications) during one to 3 weeks, associated with a characteristic 'string and beads' appearance on cerebral arteries, which resolves spontaneously in 3 months. The pathway is unknown. At early stage of the disease (at the first medical consultation) cerebral arterial abnormalities which are necessary for diagnosis are identified in only 20% of patients (brain magnetic resonance imagery (MRI) ,CT scan angiography), appearing with a delay on 2th or 3rd week after the first severe headache.. Retinal artery network is considered to be a window on brain microvasculature by sharing the same embryologic origin and physiopathology. A retinal arteriolar examination at early stage of RCVS could provide non invasively early clue to confirm diagnosis by identifying anatomical change and /or functional abnormalities at the microvascular level, whereas large cerebral artery abnormalities are still normal.
Poisoning by psychoactive substances is increasingly common in Europe and can be responsible for deaths. These substances, also called "festive drugs", circulate among other places in festive gatherings (night clubs, concerts, free music, feria, etc.). The main objective of this study is to determine the molecules that circulate in festive events in Aquitaine, in order to implement prevention actions by looking at whether the circulating substances vary with the style of event.
