Objective: To determine if watching a videotape that shows features of obstructive sleep apnea (OSA) will improve the accuracy of a verbally administered questionnaire in the prediction of OSA in pediatric snorers.

Patients And Methods: In a prospective single-blinded, randomized, controlled study at a pediatric clinic for sleep-disordered breathing, we studied children aged 0-18 years, who had been referred to a sleep laboratory for overnight polysomnography (PSG), and their parents from November 1999 to November 2000. The parents were randomized to answer a standard verbally administered panel of three questions (SQ) or a verbally administered panel of questions assisted by videotape (VQ).

Background: The correlation between obesity and severity of obstructive sleep apnea (OSA) is well established in adults, but data are inconsistent in children. We hypothesized that there is a significant correlation between the degree of obesity and the severity of OSA in children.

Methods: We retrospectively reviewed records of weight, height, history, and polysomnography of all 1- to 15- year-old children referred to our sleep laboratory.

We described a case of obstructive sleep apnea secondary (OSAS) to pharyngomalacia and laryngomalacia in a neonate with Down syndrome. She presented with oxygen requirement and paradoxical breathing without stridor. Sleep polysomnography revealed obstructive apnea (obstructive apneic index of 14 h(-1)).
