Traumatic brain injuries (TBIs) are largely underdiagnosed and may have persistent refractory consequences. Current assessments for acute TBI are limited to physical examination and imaging. Biomarkers such as glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCH-L1), and S100 calcium-binding protein B (S100B) have shown predictive value as indicators of TBI and potential screening tools. ⋯ GFAP, UCH-L1, and S100B demonstrated utility for rapid prediction of a CT-positive TBI within 0-8 hours of injury. GFAP exhibited the greatest predictive power at 12-32 hours. Furthermore, these results suggest that GFAP alone has greater utility for predicting a positive CT of the head than UCH-L1, S100B, or any combination of the 3.

Sphenoid wing meningiomas are the third most common group of intracranial meningiomas. Their management is a challenge because of their bone invasion potential and their proximity to neurovascular structures and the cavernous sinus. ⋯ Sphenoid wing meningioma is a large group with characteristics associated with skull base meningiomas and convexity meningiomas. The results of surgery and other adjuvant treatments are heterogeneous.

We sought to explore whether additional bone grafting of the atlantoaxial joint increases the bone fusion rate of iliac crest autograft in posterior occipitocervical fusion surgery. ⋯ Additional bone grafting of the atlantoaxial joint could increase the bone fusion rate of iliac crest autograft in posterior occipitocervical fusion.

Neonatal Hyponatremia in the Setting of Untreated Progressive Hydrocephalus: Case Report.
Hyponatremia in the neonatal population is an uncommon occurrence and can be associated with significant increase in morbidity and mortality. In the neonatal population, it is typically associated with an excess of antidiuretic hormone and rarely has been found to be associated with hydrocephalus, short of being caused by the subsequent treatment of hydrocephalus. ⋯ Hydrocephalus secondary to intraventricular hemorrhage is a notable complication in the premature neonatal population. Physicians should be aware of its potential association with hyponatremia and consider early neurosurgical intervention when other etiologies of the electrolyte disturbance cannot be identified.

To compare the clinical accuracy and perioperative outcomes for pedicle screw placement in transforaminal lumbar interbody fusion (TLIF) between the robot-assisted (RA) technique and fluoroscopy-guided (FG) technique. ⋯ RA pedicle screw placement is an accurate and safe procedure in TLIF for lumbar degenerative disease.
