Noise levels during cesarean delivery: a prospective observational study.

Background: Excessive noise has negative implications for both clinicians and patients. Emergency cesarean deliveries require rapid co-ordination and communication, possibly increasing noise pollution. We aimed to determine if noise levels in the Labor and Delivery operating room were higher during emergency cesarean deliveries than during non-emergency cesarean deliveries.

Kif11 dependent cell cycle progression in radial glial cells is required for proper neurogenesis in the zebrafish neural tube.

Radial glia serve as the resident neural stem cells in the embryonic vertebrate nervous system, and their proliferation must be tightly regulated to generate the correct number of neuronal and glial cell progeny in the neural tube. During a forward genetic screen, we recently identified a zebrafish mutant in the kif11 loci that displayed a significant increase in radial glial cell bodies at the ventricular zone of the spinal cord. Kif11, also known as Eg5, is a kinesin-related, plus-end directed motor protein responsible for stabilizing and separating the bipolar mitotic spindle.

The pregnant patient with congenital heart disease.

Advances in the surgical palliation and correction of congenital heart lesions have improved survival and increased the number of patients living into adulthood. Although pregnancy outcomes will be favorable for most patients with congenital heart disease, the cardiovascular challenges associated with pregnancy and delivery are best managed with a multidisciplinary approach during the puerperium. This review addresses the prevalence, physiology, risk assessment, peripartum complications, and anesthetic management of the pregnant patient with underlying congenital heart disease.

Interval, acute onset airway obstruction associated with a fracture of the C4 vertebra in a patient with ankylosing spondylitis.

We report a 92-year-old female with ankylosing spondylitis who suffered a non-displaced cervical fracture of the C4 vertebral body as the result of a mechanical fall. A rigid cervical collar was used to maintain stability. The patient later went on to develop upper airway obstruction as a result of fracture displacement.
