PURPOSE We aimed to investigate the efficacy of diffusion tensor imaging in the diagnosis of carpal tunnel syndrome and to obtain a quantitative parameter that may contribute to the diagnosis. MATERIALS AND METHODS The median nerves in 57 wrists of 38 patients diagnosed as carpal tunnel syndrome and 30 wrists of 24 normal subjects were prospectively(More)

The role of intraoperative monitoring of lower cranial nerves is not well established. In this study, the authors retrospectively analyzed the intraoperative monitoring data and the clinical outcome of the spinal accessory nerve (SAN) in patients who have undergone posterior fossa surgery. SAN was monitored in 19 patients. Subcutaneous needle electrodes(More)
Myasthenia Gravis is an acquired autoimmune disorder caused by a neuromuscular transmission defect which is clinically characterized by fluctuating weakness of voluntary muscles and fatigability. It can be diagnosed by clinical features, clinical, pharmacological and electrophysiological tests and serological evaluation. Treatment modalities include(More)
BACKGROUND Millions of people around the world regularly consume aspirin, but its value in determining stroke severity is still not clear. It has been stated that prior aspirin use might reduce the severity of ischemic stroke by reducing the size of fibrin-platelet emboli or by ameliorating platelet hyperaggregability that occurs in the microcirculation.(More)
