The incidence of ischemic stroke in young adults (18-45 years old) is increasing gradually. However, performing nutritional assessment in stroke patients is often challenging due to the lack of an accepted standard for nutritional assessment. ⋯ PNI has a statistically predictive value for the 90-day prognosis of young stroke patients.

Despite growing interest in the endoscopic endonasal approach (EEA) to the medial orbital apex (OA), a comprehensive description of the multilayer topology lying at the intersection of the regional compartments is missing. ⋯ Understanding cranial landmarks and the folds of the layers covering the orbito-cavernous-pterygopalatine interface can facilitate tailoring an EEA to the medial orbital space and avoid unnecessary exposure of sensitive anatomy in the vicinity.

It remains unclear whether spinal cord untethering is necessary to reduce the chances of neurologic decline in children with myelomeningocele and complex closed spinal dysraphism who undergo thoracolumbar fusion for scoliosis. We sought to determine the neurologic and functional outcomes of children with spinal dysraphism undergoing spinal fusion for scoliosis with and without prophylactic spinal cord untethering. ⋯ Our data suggest that prophylactic spinal cord untethering in children with spinal dysraphism undergoing thoracolumbar fusion for scoliosis may not be necessary in patients with moderate curvatures. Our conclusions are limited by the small sample size. A larger review of registry data may yield more powerful conclusions on the necessity of prophylactic spinal cord untethering in this patient population.

We aimed to evaluate the performance of fast and straightforward Murray law-based quantitative flow ratio (μQFR) computation in cerebrovascular stenosis. ⋯ The μQFR computation has a strong correlation and agrees with the FPR calculated from the pressure wire. Therefore, the μQFR might provide an essential therapeutic aid for patients with symptomatic stenosis.

To explore correlations of 3 novel radiographic parameters with myelopathy induced by posterior atlantoaxial dislocation (PAAD) secondary to os odontoideum (OO) and assess their reproducibility. ⋯ The OP/C4 SAC ratio and the C1 posterior inclination angle seem to be 2 effective and objective radiographic parameters for relating myelopathy in patients with OO with PAAD. When the OP/C4 SAC ratio is <0.93 and/or the C1 posterior inclination angle is >20°, the risk of developing myelopathy should be highly suspected in patients with OO with PAAD.
