This study examined radiographic changes in local and global spinal alignments and clinical outcomes following tumor resection without spinal fixation in patients with lumbar dumbbell tumors (LDTs). ⋯ Tumor resection without spinal fixation had no substantial impact on local and global spinal alignments and led to satisfactory clinical outcomes, suggesting that spinal fixation may not always be necessary when resecting LDTs.

Only a few articles have been published about the lateral posterior choroidal artery (LPChA), and yet none of them contains data regarding the thalamic branches. ⋯ This is the first description of the LPChA thalamic branches to date. Their microanatomic features are important for understanding the neurologic symptoms following vessels occlusion, for precise radiologic diagnoses, and for safe neurosurgical and endovascular interventions.

Aneurysmal subarachnoid hemorrhage (aSAH) is more prevalent in postmenopausal women, and it has been postulated that this relationship is hormonally driven by lower circulating levels of estrogens. We examined the association between circulating plasma estrogen levels and subsequent development of aSAH in women. ⋯ In this study, we did not find an association between estrogen levels and the incidence of aSAH in women.

Severe traumatic brain injury (TBI) is a condition burdened by high morbidity and mortality. Prevention of secondary insults is 1 of the main goals of management and intracranial pressure (ICP) monitoring is a cornerstone in management of TBI. The relationship between ICP and optic nerve sheath is known from the literature. Optic nerve sheath ultrasonography could represent a method added to our armamentarium for monitoring ICP. ⋯ We propose the use of ONSD ultrasound as a screening investigation for post-traumatic intracranial hypertension in the context of an emergency department, especially in contexts where there is limited availability of ICP monitors.

The demographics of the population with spinal cord injury (SCI) have been dynamic over time, especially as a result of aging. This study investigated the patterns of SCI admissions by age in the United States over the past decade. ⋯ The incidence of SCI increased. High cervical and incomplete injuries increased, whereas complete SCIs declined. In-hospital and 1-year mortality decreased. There was recovery in select cases of complete SCIs within 1 year.
