Filter by:This project will compare two MRI contrast agents in metastatic brain tumours in humans. More specifically, the investigators will compare the tumour contrast obtained using glucose versus the current standard gadolinium-based contrast agent (GBCA, gadobutrol, trade name Gadovist, will be used). First, participants will receive a glucose bolus injection followed by glucose enhanced MRI. Second, participants will receive a Gd-DTPA bolus injection followed by Gd-DTPA enhanced MRI. Both contrast studies will be performed during the same MRI study, which will be under one hour long.
While neurocognitive impairments in attention, memory and executive functioning are commonly reported sequelae of childhood leukemia and brain tumors, studies have only recently begun to examine the treatment of attention deficits in this population. Numerous studies have examined the effectiveness of methylphenidate in the treatment of children with attention deficit hyperactivity disorder (ADHD). However, the effectiveness of this medication for improving attention and behavioral functioning in children with medical illnesses or brain injury are less clear. Patients will be randomized to receive one week of Metadate CD (a controlled release form of methylphenidate, similar to Ritalin) and one week of placebo in a double-blind fashion.
Study Objective: Brain tumors are poorly understood. The purpose of this research is to examine whether factors in lifestyle play a role in brain tumor development. The study will also investigate the contribution of inherited susceptibility to the risk of brain cancer. By gaining a better understanding of these influences, the investigators hope to learn how to prevent brain tumors in future generations, and to develop more effective strategies for treatment. Study Protocol: This is a case-control investigation. Persons affected with a brain tumor are compared to unaffected persons on previous medical history, diet and other factors. Those enrolled in the study will participate in an interview on general background, diet, medical history and lifestyle, and will provide a sample of DNA, clippings of your toenails, and a tap water sample from your home. All procedures are performed in the clinic or through the mail. 'Cases': Cases eligible for the study are persons with a recent diagnosis of a primary brain tumor (glioma or meningioma), at least 18 years of age. 'Controls': Controls in the study are non-family members of patients, similar in age and of the same gender. Suitable controls include in-laws, friends, neighbors and co-workers.
