Filter by:This is a single arm pilot study in patients requiring surgical fusion in the foot or ankle. Patients will receive map3® Cellular Allogeneic Bone Graft containing donor matched stem cells. This cohort study will enroll 24 patients total at 1 site. After subjects have signed an informed consent, the baseline visit and examinations will be completed. Patients will be evaluated at 2 weeks, 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery.
US study to estimate the prevalence at birth of major birth defects (ie, those that cause significant functional or cosmetic impairment, require surgery, or are life-limiting) in children born to mothers who have received Nplate® therapy at any time during the pregnancy.

Interventional Neuroradiology replaces surgery. This technology requires various exposition to X rays : number of X rays photographs, radioscopy, distance between patient and detector, speed of acquisition of X-rays photographs, high tension and intensity. The manipulator must find the right balance between quality of photographs and dose delivered to the patient (optimization). Children are particularly exposed to these risks of irradiation (sensitivity to X-rays and long life expectancy with risks. So, it is fundamental to optimize the dose delivered during the procedures. The investigators propose to analyse a study comparing two protocols of optimization of doses. The investigators' hypothesis is that the protocol experimented in this trial allows less radiation of the children, compared to the usual protocol.
Test single nucleotide polymorphisms (SNP's) in ruptured and unruptured aneurysm tissue to identify a genetic difference between the two types of aneurysms; and to test SNP's in arteriovenous malformation tissue to identify a genetic link.
Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine. CCMs can bleed and cause strokes, seizures, and headaches. In some patients, CCMs affect the blood brain barrier (BBB). The BBB is the body's separation of blood and its contents in the brain from the brain tissue itself. Abnormal leakiness or permeability of this barrier can cause disease. We will measure the permeability (leakiness) of the BBB using a magnetic resonance imaging (MRI) technique called dynamic contrast-enhanced MRI (DCEMRI). The purpose of this study is to look at whether statin medications change the permeability (leakiness) of the blood brain barrier in CCM patients. Statin medications are used to lower cholesterol levels and prevent heart attack and stroke. In addition, this medication may decrease the risk of brain hemorrhage or bleeding in patients with CCM. This study will examine whether the permeability of the BBB changes following the administration of simvastatin for three months.
Exercise intolerance is a major burden for patients with complex congenital heart disease (CHD), significantly affecting their quality of life. Cardiopulmonary exercise testing provides a reliable tool both for assessing exercise capacity of CHD patients and for risk stratification and is becoming part of the routine clinical assessment of these patients. Exercise has an effect on the muscular, metabolic and circulatory systems. While exercise training has been widely studied in chronic heart failure, its efficacy in adults with CHD remain unknown. The investigators hypothesize that structured exercise training will improve exercise intolerance, in particular peak VO2. The aim of this multicenter, randomized study is to evaluate the impact of structured exercise training on exercise intolerance in patients with complex CHD.
Mullerian duct anomalies (MDAs) are relatively common disorders, with a prevalence estimated to be around 2% in the general population, and 6% to 7% in women with a history of recurrent pregnancy loss. Mullerian duct anomalies are associated with recurrent pregnancy loss, intra uterine growth retardation, and preterm labor and birth. The prevalence of preterm birth and pregnancy loss varies with the type of MDA. Patients can benefit from surgery or hysteroscopic interventions like metroplasty based on the type of MDA. Therefore, to optimize patient outcomes, accurate diagnosis and description of MDAs is essential. Magnetic resonance imaging (MRI) is an excellent way of evaluating the uterus for MDAs. MRI, although costly, is less expensive than laparoscopy and hysteroscopy and is non-invasive. Pellerito et all evaluated 26 women with surgically proven MDAs and found that in 24 cases MRI was able to correctly diagnose the MDAs. Therefore MRI is generally considered as a reference standard for uterine evaluation. In a study comparing MRI and endovaginal Two-Dimensional Ultrasound (2DUS), MRI appeared to be more accurate than 2DUS with a sensitivity of 77%, specificity of 33%, and a positive predictive value of 83%. Endovaginal Three-Dimensional Ultrasound (3DUS) is a relatively new technology that creates three-dimensional volumes from a series of two-dimensional images. This technique allows the user to acquire coronal or face-on-view of the uterus which is essential in evaluating the uterus for the presence of MDAs. Kupesic and Kurjak used 3DUS to evaluate 86 patients and found that it had sensitivity of 98.38%, specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 96% in the diagnosis of septate uteri [7]. Endovaginal 3DUS is less expensive, less invasive, and less-time consuming than hysteroscopy or MRI and appears to be a very promising technology for the evaluation of MDAs. 3DUS appears to be at least as accurate as MRI in the diagnosis of MDAs. In addition, 3DUS is less expensive than MRI and in some patients better tolerated. If validated using prospective studies, 3DUS has the potential to become the reference standard for the diagnosis of MDAs.
The purpose of this clinical trial is to examine the effect of non-invasive cortical activation by specific patterned auditory stimulation (Mozart K448- Piano Sonata for Two Hands in D Major), in altering or eliminating photoparoxysmal abnormalities. Recent work has indicated that such evoked activity (i.e. by specific music) can result in significant reductions, or even complete termination of epileptiform activity and/or seizures across a broad range of individuals with epilepsy. A hypothesis is generated that specific music activation would beneficially effect photoparoxysmal based epileptiform abnormalities.
The aim of this study is to see weather hyperbaric oxygen treatment is beneficial as adjuvant treatment for frost damage. The investigators hope to include at least 20 patients in a randomized manner. Half of the patients are randomized to hyperbaric oxygen, and half of the patients are randomized not to have hyperbaric oxygen treatment. Under hypotheses: The number og surgeries is reduced by hyperbaric oxygen treatment as adjuvant treatment for frost damage. The functional level of the frost damaged patient is better after 6 and 12 months when also treated with hyperbaric oxygen treatment for frost damage.
