To evaluate PK and PD responses to L-citrulline given orally for four weeks to patients with sickle cell disease who are otherwise healthy.
The overall purpose of this study is to compare the effects of mannitol and hypertonic saline on patients with increased intracranial pressure. The hypothesis being tested is that hypertonic saline is more effective in controlling increased intracranial pressure than mannitol.
International surveys about pathological gambling estimate that there are about 1 to 3 per cent of gamblers who develop a pathological behavior about gamble.In France, pathological gambling is not a priority of public health, in contrast with other addictive disorders, like alcoholism or nicotine addiction. The aim of our study is to describe accurately for the first time in France, a sample of “at risk” and pathological French gamblers. We want to collect socio-demographical and clinical data from this subjects (story of the addictive behaviour, co morbidities, and more specifically, detailed study of pathological gamblers’ personality), in order to compare our data with those of international literature.Secondarily, we want to test the feasibility of this kind of detailed evaluations for another study planned for 2007-2008 and which purpose will be to compare pathological gamblers’ personality characteristics according to the kind of game that they mainly practice.The participation at the study will be proposed to every patient consulting in the “service d’addictologie du CHU de Nantes”. The study consists in a single evaluation (about 8 hours) with standardized tools used all other the world.
24 test persons are treated with a dye suspension followed by a laser intervention. A decrease of hair density is expected.
In this study, test persons with chronic excessive UV radiation and a control group are examined by multiphoton laser imaging and biophysical methods in order to evaluate the dermal fiber network. We expect to observe signs of advanced skin aging in the test group.
Cervical anastomotic leak is one of the most common complications after trans-hiatal esophagectomy. Hypothesis: An early post operative administration of a pro-kinetic dosage of erythromycin will reduce leak occurrence. Design: This is a prospective, randomized, double blind, placebo controlled study. Number of patients: 30. Inclusion Criteria: - Patients after trans-hiatal esophagectomy Exclusion Criteria: - Allergy to erythromycin - Use of phenothiazine - QT prolongation - Liver function test (LFT) abnormalities - Myasthenia gravis - Cardiomyopathy
Harmonic scalpel is a new surgical instrument. Its use has been recommended in patients submitted to total thyroidectomy. Few randomized controlled trials has been published. However they had small sample sizes, used intermediate outcomes and included different surgical procedures. Our objective is to asses the use of Harmonic scalpel in patients submitted to total thyroidectomy using surgical complications, operative time, drainage volume, postoperative pain, length of stay and costs as outcomes. Our hypothesis is that Harmonic scalpel decreases operative time,drainage volume, postoperative pain, length of stay and costs without increasing surgical complications
The goal of this study is to evaluate the proportion of subjects both antiretroviral experienced and virologically suppressed on lopinavir/ritonavir (LPV/r)400/100mg twice daily who maintain viral suppression after switching to lopinavir/ritonavir (LPV/r)800/200mg once daily. The hypothesis for this study is that the majority of subjects will remain virologically suppressed with once daily dosing versus twice daily dosing and therefore quality of life will be improved with the once daily dosing of lopinavir/ritonavir (LPV/r)800/200mg.
Enemas are not anymore used routinely before vaginal deliveries.The intention of this study is to elucidate whether there is a benefit in routine use of enema before cesarean section.
