Optic Nerve Diameter on Non-Contrast Computed Tomography and Intracranial Hypertension in Patients With Acute Brain Injury: A Validation Study.

Intracranial hypertension is a feared complication of acute brain injury that can cause ischemic stroke, herniation, and death. Identifying those at risk is difficult, and the physical examination is often confounded. Given the widespread availability and use of computed tomography (CT) in patients with acute brain injury, prior work has attempted to use optic nerve diameter measurements to identify those at risk of intracranial hypertension.

Twice Daily Compared to Three Times Daily Hydrocortisone in Prepubertal Children with Congenital Adrenal Hyperplasia.

Introduction: Glucocorticoid therapy in children with congenital adrenal hyperplasia (CAH) must be finely balanced between optimizing adrenal control and minimizing side effects. Twice (BID) rather than three times daily (TID) hydrocortisone may provide similar adrenal control and reduce metabolic risk. We compared BID and TID regimens with respect to adrenal control, growth, and metabolic effects.
