Randomized Controlled TrialThe new age of play audiometry: prospective validation testing of an iPad-based play audiometer.
The timely diagnosis of hearing loss in the pediatric population has significant implications for a child's development. However, audiological evaluation in this population poses unique challenges due to difficulties with patient cooperation. Though specialized adaptations exist (such as conditioned play audiometry), these methods can be time consuming and costly. The objective of this study was to validate an iPad-based play audiometer that addresses the shortcomings of existing audiometry. ⋯ The tablet audiometer is a valid and sensitive instrument for screening and assessment of warble-tone thresholds in children.

Corrosion casting of the subglottis following endotracheal tube intubation injury: a pilot study in Yorkshire piglets.
Subglottic stenosis can result from endotracheal tube injury. The mechanism by which this occurs, however, is not well understood. The purpose of this study was to examine the role of angiogenesis, hypoxia and ischemia in subglottic mucosal injury following endotracheal intubation. ⋯ Subglottic injury due to intubation and hypoxia may lead to decreased angiogenesis and increased blood vessel damage resulting in extravasation of fluid and a decreased propensity toward wound healing in this animal model.
