Background And Objective: The purpose of this study is to assess whether Chinese children with high apnea-hypopnea index (AHI) are sleepier by a modified Epworth Sleepiness Scale (ESS).
Materials And Methods: Records were retrospectively reviewed. We included children who were between 3 and 12 years old, admitted for overnight polysomnogram because of suspected obstructive sleep apnea syndrome (OSAS).
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.
Introduction: Obstructive sleep apnea syndrome (OSAS) is a known risk factor for hypertension in adults. This relationship is less clear in childhood OSAS.
Objective: This study examined the relationship between OSAS and 24-h ambulatory BP (ABP), a more accurate assessment than casual BP, in children with snoring.
Unlabelled: Habitual snoring or daily snoring is a symptom of sleep-disordered breathing (SDB) in children and it is reported in about 10% of children. SDB includes primary snoring, upper airway resistance syndrome (UARS), obstructive hypoventilation syndrome and obstructive sleep apnea syndrome (OSAS). Classification of SDB in a particular snoring child requires an overnight polysomnography (PSG).
