The aim of this study was to determine the impact of preoperative pulmonary risk factors (PRFS) on surgical outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). ⋯ Our study showed that PRF may be a risk factor for slightly longer hospital stays without higher rates of complication or unplanned readmission for patients with AIS undergoing PSF and thus should not preclude surgical management.

It is difficult to correctly identify the ruptured aneurysm in patients with multiple intracranial aneurysms. Here, we investigated the clinical characteristics of ruptured intracranial aneurysms in such patients. ⋯ The results of this study indicate that the aspect ratio is the most predictive factor of a ruptured intracranial aneurysm in patients with multiple intracranial aneurysms.

Microvascular decompression (MVD) is considered the only etiological treatment for drug-resistant trigeminal neuralgia (TN). Nonetheless, despite the recent technological advances, the risks associated with MVD remain non-negligible. The aim of this study was to evaluate the impact of using neuronavigation on the surgical outcomes of patients with TN submitted for MVD. ⋯ Neuronavigation is a useful tool that significantly reduced craniotomy size, surgical duration, and CSF leak incidence in patients with TN submitted for MVD. We advise to routinely implement neuronavigation in this type of surgery.

We sought to measure the coronal alignment of the lumbar spine of patients in the right lateral decubitus position on a hinged Jackson operating table with the following 3 table positions: neutral and right and left 20-degree flexion. ⋯ The coronal alignment of the lumbar spine of patients in the right lateral decubitus position on a flat operating table (neutral position) was convex. The right 20-degree flexion position of the hinged operating table yielded less coronal plane lumbar spine deformity, with greater deformity in women.

The T2-FLAIR mismatch sign is a useful imaging sign in clinical magnetic resonance imaging studies for detecting isocitrate dehydrogenase (IDH)-mutant 1p/19q non-codeleted astrocytomas. However, the association between the mismatch sign and pathologic findings is poorly understood. Therefore, the aim of this study was to elucidate the relationship of histopathologic and radiologic features with the mismatch sign in IDH-mutant 1p/19q non-codeleted astrocytomas. ⋯ This study provides evidence that a region-dependent microstructural difference could reflect the mismatch sign in IDH-mutant 1p/19q non-codeleted astrocytomas. Core of the mismatch sign characteristically had microcystic changes accompanied by higher ADC values, whereas Rim had abundant neuroglial fibrils and cellularity accompanied by lower ADC values.
