Filter by:Brittle Cornea Syndrome and Ehlers-Danlos Syndrome (EDS) type VI are rare collagen-connective tissue disorders that predispose affected individuals to the development of perforated corneas from the mildest of eye trauma or even spontaneously. Clinical studies evaluating riboflavin-corneal crosslinking have found that it dramatically increases corneal rigidity. Given the success and safety of riboflavin crosslinking, the investigators believe that it can increase the corneal stability in patients affected these disseases, preventing perforation. It is furthermore possible, that riboflavin crosslinking will allow corneal transplants to successfully be performed on blind eyes that have already perforated and opacified. The purpose of the study is to determine whether corneal crosslinking can be safely performed on individuals with Brittle Cornea Syndrome or Ehlers-Danlos Syndrome type VI.
Comparing whether intravenous immune globulin or plasma exchange is superior in treating mechanically ventilated children with Guillain Barre syndrome.
Term and near term newborns can present acute respiratory distress syndrome (RDS). Surfactant treatment has been shown effective in reducing mechanical ventilation and oxygen treatment durations in the preterm newborn. Whether surfactant treatment is beneficial for term and near term newborns is unknown. The purpose of this study is to compare surfactant treatment vs. nasal continuous positive airways pressure in the newborn between 35 and 41 weeks of gestation with RDS within the first 24 hours of life. The study's primary endpoint is "survival with no oxygen treatment at 72 hours of life". The secondary endpoints are: death, surfactant treatment, pneumothorax, secondary infections, pulmonary hypertension, inhaled nitric oxide treatment, fluid loading treatment, vasopressive amines treatment, mechanical ventilation duration, nCPAP treatment duration, Oxygen treatment duration, Oxygen treatment at 28 days of life, hospitalization duration and treatment strategy cost.
A phase I/II study of the efficacy and safety of an intensified schedule of Azacitidine (Vidaza®) in intermediate-2 and high risk MDS patients.
This randomized phase III trial is studying how well Caphosol rinse works in preventing mucositis in young patients undergoing autologous or donor stem cell transplant. Supersaturated calcium phosphate (Caphosol) rinse may be able to prevent mucositis, or mouth sores, in patients undergoing stem cell transplant.
Patients will receive escalating doses of ldarubicin combined to Azacitidine given at the FDA/EMEA approved Schedule and dosing. For the Phase I study : Determine the safety and tolerance of escalating doses of Idarubicin combined to Azacitidine in patients with INT-2 or higher risk MDS. For the phase II study: Primary: Evaluate rate and duration of response (according to IWG 2006 criteria and IWG 2000 criteria) to the combination of Idarubicin and Azacitidine in patients with INT-2 or higher risk MDS
Osteosarcoma is the most common malignant bone tumor in children and adolescents. Because cure rates for osteosarcoma have remained stagnant for the past several decades despite numerous trials of chemotherapy agents, novel therapies based on the understanding of the molecular pathogenesis of osteosarcoma are needed. Rothmund-Thomson Syndrome (RTS) is a genetic disorder affecting many parts of the body and resulting in major skeletal abnormalities. This disease also has the propensity to increase the risk of developing cancer, particularly osteosarcoma. Two-thirds of RTS patients have a high risk of developing osteosarcoma. Therefore, it is important to understand the impact of RTS on the skeletal phenotype (as measured by bone density) in order to develop effective therapies to battle osteosarcoma.
Irritable bowel syndrome (IBS) is a common disorder affecting up to 20% of the general population. Despite the prevalence of the disorder, it remains poorly understood. This is reflected in a symptom based diagnostic scheme, the lack of a suitable biological marker and inadequate treatment options. Current knowledge suggests the disorder is as a result of a dysregulated brain-gut axis, a complex construct describing the bidirectional communication systems underpinning normal gastrointestinal functioning. The investigators hypothesize here that the disruption of this brain-gut axis is facilitated by an increased degradation of tryptophan along the kynurenine pathway. This metabolic abnormality has the potential to impact on both GI and CNS signaling through its effects on serotonergic signaling and the impact of metabolites like kynurenic acid and quinolinic acid on cognitive processes respectively. Previous data from our laboratory indicated increased tryptophan degradation in IBS patients and suggested the metabolites produced as putative biological markers of the condition. In this study the investigators aim to reconcile cognitive impairment in IBS with GI and CNS symptom severity and kynurenine pathway metabolites. The investigators will establish these baseline measures in IBS compared to control subjects. A battery of cognitive assessments will be carried out using a computerized testing system. Standardized rating scales will be used to assess GI and CNS symptom severity. GC-MS/MS, a recently acquired technology platform in our laboratory, will be used to quantify plasma quinolinic acid levels.
The purpose of this study is to measure the effect of ranolazine on ETT (exercise treadmill test) exercise duration in four ethnic subgroups with established coronary artery disease and risk factor(s) for the metabolic syndrome: Caucasian, African American, Southeast Asian and East Indian.
Irritable Bowel Syndrome with diarrhoea (IBS-D) is a functional gastrointestinal disorder characterised by chronic or recurrent abdominal pain or discomfort and diarrhoea. This trial aims at the evaluation of the efficacy and safety of the neurokinin type 2 receptor antagonist Ibodutant in improving IBS-D symptoms.
