Stridor at birth predicts poor outcome in neonates with myelomeningocele.

Background: Stridor, associated with vocal cord paralysis, in neonates with myelomeningocele (MMC) is a recognized symptom related to Chiari II malformation (CM). In most children, stridor appears after birth. Control of hydrocephalus, if present, and urgent decompression of the CM are recommended for treatment of these patients.

Cervical spine instability following cervical laminectomies for Chiari II malformation: a retrospective cohort study.

Objective: The treatment of symptomatic Chiari II malformations typically involves multilevel cervical laminectomies in very young children. These patients are at significant risk of cervical instability. The purpose of this study was to determine the incidence and significance of cervical instability after multilevel cervical laminectomies in a cohort of patients decompressed for Chiari II malformation.

Monitoring brain oxygen saturation during coronary bypass surgery: a randomized, prospective study.

Background: Cerebral deoxygenation is associated with various adverse systemic outcomes. We hypothesized, by using the brain as an index organ, that interventions to improve cerebral oxygenation would have systemic benefits in cardiac surgical patients.

Methods: Two-hundred coronary artery bypass patients were randomized to either intraoperative cerebral regional oxygen saturation (rSO2) monitoring with active display and treatment intervention protocol (intervention, n = 100), or underwent blinded rSO2 monitoring (control, n = 100).

The impact of prenatal diagnosis on neural tube defect (NTD) pregnancy versus birth incidence in British Columbia.

The birth incidence of neural tube defect (NTD) cases in British Columbia (B.C.), and elsewhere in North America, is reported to be declining.
