Interstim Therapy InterStim therapy is a pacemaker for the bladder used to reestablish appropriate nueromodulation of the bladder. The device works by using a stimulator device in the buttocks to stimulate the S3 nerve root in the pelvis. This is the primary nerve root for bladder function.
Purpose: To prospectively assess sensitivity and specificity of diffusion indexes of the corpus callosum (CC) for differentiating relapsing neuromyelitis optica (RNMO) from relapsing-remitting multiple sclerosis (RRMS), by using final clinical diagnosis as the reference standard. Materials and Methods: Participants provided informed consent; the study was approved by the institutional review board. Forty-six consecutive patients with RRMS (18 men, 28 women; mean age, 37.7 years; range, 18–58 years) and 26 consecutive patients with RNMO (two men, 24 women; mean age, 38.6 years; range, 19–59 years) underwent diffusion-tensor magnetic resonance imaging.
Background: Neuromyelitis optica (NMO) is an inflammatory disease associating optic neuritis and myelitis. Recently, several works showed that optical coherence tomography (OCT) should be an interesting method of disease severity.
