Filter by:The purpose of the study is to determine if triheptanoin is an effective treatment for the symptoms of Adult Polyglucosan Body Disease.
The purpose of this study is to measure the prevalence and severity of cardiac autonomic neuropathy (CAN), diabetic autonomic neuropathy (DAN) which in non-diabetics is termed advanced nervous system (ANS) dysfunction, and autonomic dysfunction as well as the overall sympathovagal balance (SB) in the CEFH population of diabetic patients versus non-diabetic patients undergoing elective vitreoretinal surgery.
Therapeutic management of gait disorders in very advanced Parkinson's disease (PD) patients can sometimes be disappointing, since dopaminergic drug treatments and subthalamic nucleus (STN) stimulation are more effective for limb-related Parkinsonian signs than for gait disorders. Gait disorders could be also partly related to noradrenergic system impairment, pharmacological modulation of both dopamine and noradrenaline pathways could potentially improve the symptomatology. The investigators have demonstrated using an open label study on 17 advanced PD patients that chronic, high doses of methylphenidate (MPD) improved gait, freezing of gait, motor symptoms and attention in the absence of L-Dopa and increased the intensity of response of these symptoms to L-Dopa (Devos et al., 2007). The investigators aimed to confirm their results using a randomized, double-blind, placebo-controlled, parallel-group, multicentric trial. The investigators will assess the clinical value of chronic, high doses (1 mg/kg/day) of MPD vs placebo in 88 non demented PD patients suffering from severe gait disorders with freezing despite their use of optimal dopaminergic doses and eventually STN stimulation parameters. Efficacy will be assessed directly and on video in the absence of L-Dopa and again after acute administration of the drug, both before and after a 3-month course of MPD, using Stand Walk Sit test (primary criteria), the "Freezing Of Gait trajectory", RGSE scale, the UPDRS scores, the dyskinesia rating scale, Achiron scales and using auto-questionnaires of Giladi, ABC scale and PDQ 39. Attention will be assessed using reactions times. Drowsiness will be assessed using Epworth and Parkinson's disease Sleep Scales. Apathy and depression will be monitored with Lille Apathy Rating Scale, MADRS, BPRS, MINI and psychiatric interview. Cardiologic and general tolerance will be also monitored. This study could lead to propose methylphenidate with a good efficacy/ risk balance in advanced PD patients suffering from severe gait disorders with freezing of gait, drowsiness and attention deficit.
The study will test whether damage of the heart nerves appears in patients before they develop diabetes.
This study aimed to investigate effects of physical training on exercise capacity and changes of heart rate variability (HRV) at rest, during exercise, and post-exercise in the patient with diabetes with autonomic neuropathy (DAN).
Human fibroblasts and possibly other human somatic cells may be reprogrammed into induced pluripotent stem (iPS) cells by the forced expression of transcription factors (1-5). The iPS cells seem to share many properties with human embryonic stem cells. Induced pluripotent stem cells potentially may be useful in the future as an unlimited source of cells for transplantation. The major goal of the project is to develop human iPS cells from cell cultures from skin biopsies or the patient's hair. The iPS cells will be developed primarily for modeling diseases and drug discovery as well as basic research, and for developing the technology that may eventually allow the use of iPS cells for future transplantation therapy. The iPS cells developed in the course of this application are not intended for use in transplantation therapy. Future development of iPS cells for clinical transplantation therapies will be subjected to the appropriate authorization by ethical and regulatory committees.
The purpose of this study is to determine if non-dilated retinal photography in the emergency room improves the diagnosis of papilledema (optic nerve swelling) in patients with neurologic disease compared to direct ophthalmoscopy.
Chemotherapy for the treatment of breast cancer can affect nerves and muscles leading to loss of sensation in the hands and feet for feeling hot and cold, difficulty walking, and muscle weakness. This study will explore if exercises such as walking and strength training may prove helpful in preventing or lessening chemotherapy-induced peripheral neuropathy from chemotherapy, making the therapy easier to tolerate and increasing overall quality of life.
The central hypothesis in the present project is that general anesthesia may alter autonomic control such that perioperative coronary blood flow (CBF) is significantly disturbed. These disturbances in coronary blood flow may contribute to the development of myocardial ischemia in the perioperative period. Furthermore, patients with an intrinsically altered autonomic sympathetic innervation, like diabetics, are even more prone to develop perioperative disturbances in coronary blood flow. Here the researchers will investigate what the direct effects are of general and locoregional anesthesia on the CBF. Furthermore, the researchers aim to evaluate whether diabetic subjects show more disturbed CBF responses to anesthesia as compared to non-diabetics.
The search for metabolic abnormalities in patients with neurological disorders represents an important challenge 1) to identify new potentially treatable inherited metabolic diseases, and 2) to identify biomarkers or new treatments in more common neurodegenerative or neurogenetic disorders. This approach is currently limited by the fact that techniques aiming at identifying abnormal metabolites in human fluids (metabolomics) only detect subsets of molecules and that no general assays is available to detect abnormalities in the metabolism of complex molecules that takes place within cell organelles. As a consequence, only limited parts of the metabolism can be studied simultaneously. The aim of this study is to evaluate whether NRM spectroscopy of body fluids (urines, cerebrospinal fluid) could allow to detect new metabolic abnormalities in patients with complex neurological diseases.
