OBJECTIVE To investigate the degree of ossification and the frequency of ankylosis between the atlas and the dens of the axis in patients with longstanding ankylosing spondylitis (AS), to assess radiological involvement of the cervical spine, and to determine their correlations with structural severity and clinical variables, including neurological abnormalities. METHODS In 61 AS patients wit...

Background: Chronic inflammatory neuropathies can present with a sensory ataxia due to involvement of dorsal root ganglia (DRG) or sensory nerves. Selective inflammatory involvement of sensory nerve roots proximal to the DRG has been postulated. Methods: The authors identified 15 patients with a sensory syndrome and normal nerve conduction studies. Sensory nerve root involvement was suggested b...

Background: Surgical interventions around spinal roots may result in rootlets injury and neurological deficits. Multimodal introperative neurophysiological monitoring (MIOM) can allow for early detection and then reversal of nerve roots potential injuries. These utilities have been currently used to evaluate spinal sensorimotor pathways and nerve root function during posterior spinal approches ...

Functional imaging soon will become as important as anatomic imaging in presurgical planning. Anatomic imaging, such as computed tomography (CT) and magnetic resonance (MR), have greatly enhanced the ability of a neurosurgeon to detect and safely resect intracranial lesions. Intraoperative locating devices, such as optical digitizers, have effectively coupled these imaging advances to the actua...

The red persistent luminescence phosphors SrS: Eux2+, Pry3+ (x = 0∼0.001, y 0∼0.003) were synthesized by the solid-state reaction method in a weak reducing atmosphere of active carbon. synthetic parameters, photoluminescence characteristics, and dynamic properties thermoluminescence studied systematically. According to results spectra Pry3+, energy level scheme was confirmed quantitatively. Bas...
