Filter by:Despite the high prevalence of low back pain, little is still known about its underlying pathology. Only a small proportion of people (~1%) have a diagnosable pathoanatomical entity causing low back pain. The other types of back pain are classified as non-specific low back pain. Thus, current back pain management typically focuses on relieving symptoms. This is largely ineffective without understanding the cause. Yet, there are some pathologies which are thought to be associated with low back pain. Vertebral bone marrow oedemas are now known to be a hallmark feature for low back pain. There are three types of vertebral bone marrow oedemas. Type I oedemas are dynamic lesions that may progress to a higher grade, stop, or even return to normal. Although the precise cause of type I oedemas is not well understood, loading on the spine plays a key role in its development. Lumbar braces are known to reduce loads on the spine. Thus, they may reduce the size of oedema by modifying loads on the spine. The investigators already know that wearing a lumbar brace reduces pain in people with back pain and type I vertebral bone marrow oedemas. Unfortunately, there is no study showing that pain reduction with bracing is associated with a reduction of oedema. The goal of this study is to determine if wearing a lumbar brace for six weeks will reduce the dimensions of type I vertebral bone marrow oedema.
Pain is complex phenomenon misunderstood in spite of medical progress and neurosciences. That's why the relief of chronic pain is only partial for a lot of infection as arthrosis, chronic back pain, headaches or neuropathic pain. Certain situations bring to relive pain sensation. Investigators were interested to former burned. They wonder about somatic memory and unconscious of acute.
Aim of this trial is to investigate feasibility of cardiac magnetic resonance imaging (cMRI) in patients with long term implanted coradial leads upgraded to an MRI conditional pacemaker system, to assess MR-image quality and to prove the safety of MRI in this specific population in the short term as well as during long term follow-up.
This is an open-label, multi-center study involving babies 0-2 months of age who have liver problems (pathology) and need to have their liver and possibly, the bile ducts imaged using magnetic resonance imaging and injection of a contrast agent (dye). This agent is called Eovist. It has been marketed since 2004 and used in many countries all over the world. The baby will have blood tests before and after the imaging is done to make sure that there are no unexpected findings before and after the imaging. Also 3 blood samples up to 8 hours after the injection will be obtained in order to measure how much of the dye is in the blood. The baby will have an intravenous line which can be used for the blood samples and will not need to be stick for the blood samples. Several radiologists will evaluate the images. The family doctor will be contacted to find out what was the diagnosis and treatment after the results of the MRI were known. Six months after the study, the parent(s)/legal guardian(s) will be contacted to make sure the that baby did not have any problems, especially with the skin, joints and eyes.
The goal of this study is to determine if there is a significant difference in the quality of care between the investigators' two standard anesthesia techniques for children undergoing a MRI of the body and/or extremity MRI. Quality of care will be measured by time spent in the MRI room as well as parental satisfaction, frequency of interruptions of the MRI scan, incidence-severity of respiratory complications, post anesthesia agitation, and time spent in the induction room, MRI room, and Post-Anesthesia Care Unit (PACU).
