Does the preoperative lumbar sagittal profile affect the selection of osteotomy level in pedicle subtraction osteotomy for thoracolumbar kyphosis secondary to ankylosing spondylitis?
To investigate the different preoperative lumbar sagittal profiles of ankylosing spondylitis (AS) patients and the selection of osteotomy level for one-level pedicle subtraction osteotomy (PSO) for the correction of thoracolumbar kyphosis. ⋯ Patients in group B had significantly worse preoperative sagittal alignments compared to group A. The distribution of osteotomy levels varied between the 2 groups due to the different lumbar profiles; however, satisfactory correction was achieved in both groups. The preoperative lumbar profiles need to be considered in selecting the optimal osteotomy level. Patients with kyphotic lumbar profiles are suitable candidates for PSO at L2/L3, while L1/L2 PSO is appropriate for patients with lordotic lumbar profiles.

Anteromedial GPi deep brain stimulation in Tourette syndrome: The first case series from Iran.
Tourette syndrome (TS) is a neuropsychiatric disorder characterized by childhood onset motor and phonic tics. In refractory cases, deep brain stimulation (DBS) with different targets including anteromedial Globus pallidus (AM-GPi) looks promising. ⋯ Results of our study in accordance to previous ones suggest AM-GPi DBS as an effective and well-tolerated therapeutic modality for patients with medication refractory TS.
