Filter by:This randomised, double-blind, placebo-controlled clinical trial investigates the neuroprotective effect of rasagiline in patients suffering from a retinal detachment affecting central vision. Based on results from a study in mice suffering from retinal degeneration, the investigators hypothesize that rasagiline delays neurodegeneration in the retina and improves visual acuity outcomes after retinal detachment surgery. Rasagiline is a second-generation propargylamine with neuroprotective properties modulating the caspase-dependent pathway of programmed cell death.
We propose a prospective multicenter study, whose originality lies in the inclusion of the naive child and adolescent population. Its purpose is to evaluate the incidence of adverse events related to the use of l antipsychotic drugs in children and adolescents with no history of taking such drugs. The inclusion criteria will be: (1) male or female inpatients, (2) aged from 6 to 18 years, (3) requiring antipsychotic treatment, (4) receiving antipsychotic drug for less than 28 days without taking antipsychotic before or with a history of antipsychotic over a maximum period of three consecutive months and discontinued for at least 6 months. Therapeutic monitoring during the 12 month study period will include clinical assessments and laboratory testing. These assessments will be performed before treatment (at inclusion), and at 1, 3, 6, 9, 12 months after the introduction of the antipsychotic drug.
The purpose of this is study is to assess the efficacy of pre-operative intravitreal bevacizumab (IVB) (Genentech, South San Francisco CA) in improving visual acuity, reducing operative time, complications, intra-operative and post-operative hemorrhage following small gauge pars plana vitrectomy (PPV) (23-gauge, 25-gauge or 27-gauge ) compared to small gauge PPV (23-gauge, 25-gauge or 27-gauge) alone in eyes with tractional retinal detachment (TRD) secondary to proliferative diabetic retinopathy (PDR). Hypothesis: Preoperative IVB may be beneficial for membrane dissection in diabetic tractional retinal detachment with minimally invasive vitreoretinal surgery (23-gauge transconjunctival sutureless vitrectomy [TSV]). In addition, post-operative rebleeding may be decreased.
The purpose of this study is to examine the effects of a drug called bevacizumab (Avastin) on the rates of recurrent retinal detachment and scar tissue formation.
Background: Rhegmatogenous retinal detachment is an ophthalmic emergency that, without surgical repair, often leads to blindness. The incidence is about 1/10000/year. The leading causes are myopia and aging which cause retinal tears often resulting in retinal detachment. Patients commonly experience photopsia, floaters, and peripheral visual field loss. Two different general surgical treatment options exist for retinal detachment; scleral buckling or vitrectomy. However, the precise indications for each approach have not been well established. Correct classification of the retinal detachment is important. The first step is to decide whether an intra- or extra-ocular surgical approach is more appropriate. Simple rhegmatogenous retinal detachments are usually treated extraocularly with scleral buckling surgery, whereas more complicated cases require intraocular primary pars plana vitrectomy and one or more of gas, silicone oil, laser therapy, or cryotherapy. Study objectives: The purpose of this study is to evaluate different surgical techniques for the treatment of retinal detachment. Data relating to retinal status before treatment, surgical treatment, post-operative anatomy and visual acuity, post-operative OCT, and intra- and post-operative complications will be collected. Vitreous cytokines will also be analyzed to monitor intravitreal inflammation as a result of retinal detachment.
The schizophrenic disorders and pervasive developmental disorders are neurodevelopmental disorders distinct origin who share common challenges to engage and maintain social relationships and mutual disturbances of affective contact. An important issue of research is to determine the cognitive and brain mechanisms underlying social disability in these two pathologies. Several lines of social cognition have been systematically explored: the perception of emotions, the ability to attribute intentionality and mental states to others (theory of mind), the understanding of social situations in different contexts. We made the observation today that research findings clearly in the field of autism and schizophrenic disorders that converge on common patterns neurocognitive abnormalities. Consequently, many programs support published today use the same therapeutic targets and the same tools in both pathologies. This raises two questions of science: (1) whether the disorders of social cognition reported in the field of autism and schizophrenia are "specific deficit" and not "specific condition", that is to say they are inherent social disadvantage whatever condition or (2) if these disorders of social cognition is a pattern common to autism and schizophrenia but are the result of specific neurocognitive mechanisms and different in each these pathologies. Systematic exploration of these issues is a current issue for understanding the pathophysiological borders between the two neurodevelopmental disorders but also to better define the potential targets of therapeutic strategies, psycho-educational and remediation of disorders of social cognition in autism and schizophrenia. Main objective: To compare clinical cognitive profiles in adolescents with a schizophrenic disorder, autistic or healthy in the three areas of social cognition: perception of emotions, attribution of intentions to others (theory of mind) and style attribution. We shall constitute three population groups of patients, a group of patients meeting the diagnosis of schizophrenia, a group of patients with autism and a control group (healthy subjects).
Patients with retinal detachment do not always recover good visual function. Sometimes simple causes are responsible. Other causes can only be discovered thanks to high-resolution imaging provided by the latest generation of OCT. This study is possible thanks to surgical teams who have a strong recruitment potential, with the experience of a joint project in 2007-2008 (PHRC national - Etude DOREMY, Etude FRIENDS) to define more strict intervention criteria. The principal objective of this study is to better define with regard to time: - The onset of surgically curable or transient macular affections, and losses in visual acuity that can be qualified as "explained" - But above all to better understand the relationships between anatomical analyses obtained using OCT and autofluorescence and functional analysis using visual acuity and microperimetry. - In the near future, two techniques (OCT and microperimetry) will certainly become essential tools in the evaluation of macular function. Better understanding of these relationships is the first necessary step in any study concerning the therapeutic prevention of retinal lesions related to retinal detachment: This study will make it possible to define criteria for the evaluation of anatomical and functional recovery, their relationship with each other and finally their evolution over time. This is an essential first phase before possible therapies can be evaluated.
This study is a comparison (23 gauge vs 20 gauge instrumentation) of surgical instrumentation for retinal detachment repair.
The purpose of this research study is to compare the outcomes of pneumatic retinopexy with the outcomes of vitrectomy (with or without scleral buckle) for the management of retinal detachment, in terms of anatomical success, functional success and impact on patient quality of life.
Schizophrenia beginning before 18 years is a clinical entity not well known because of its low incidence and difficulties in the clinical diagnosis. However, in the investigators clinical practice, due to the specialization of the investigators service, the investigators are led to hospital to receive important feel active of patients meeting the Diagnostic and Statistical Manual of Mental Disorders IV text revision (DSM IV-TR) precose schizophrenia. The work of us team on the theme of the relationship between Pervasive Developmental Disorders and precose Schizophrenia led us to hypothesize that a number of children in care in the medical and educational institutes, hospitals and day shelters therapeutic part-time symptoms of schizophrenia or a line real early diagnosis of schizophrenia undervalued or not diagnosed. The main goal is to estimate the prevalence of dissociative disorders in a population of children in care institutions and medical education in child psychiatry in hospitals and others structures.
