Objective Due to limitations of polysomnography (PSG), novel ways to evaluate pediatric obstructive sleep apnea (OSA) are needed. Urinary leukotriene E4 (LTE4), an inflammatory marker, has been identified as a potential biomarker for pediatric OSA. The objective of the study was to assess whether urinary LTE4 levels correlate with OSA severity, as determined by obstructive apnea-hypopnea index (AHI) and nadir oxygen saturation. Study Design Prospective trial. Setting Tertiary care children's hospital. Subjects and Methods Children (age, 3-16 years) with sleep-disordered breathing (SDB) who were referred for PSG were included...

Importance: Hypertension in childhood may continue into adulthood and lead to adverse cardiovascular outcomes. Evidence suggests that adenotonsillectomy for childhood obstructive sleep apnea (OSA) may be associated with blood pressure (BP) improvement. However, how adenotonsillectomy is associated with BP in hypertensive and nonhypertensive children with OSA remains unclear. Objective: To investigate disparities in BP changes after adenotonsillectomy in hypertensive and nonhypertensive children with OSA...

BACKGROUND AND OBJECTIVE: The aim of this study was to assess the utility of bispectrum-based oximetry approaches as a complementary tool to traditional techniques in the screening of pediatric sleep apnea-hypopnea syndrome (SAHS). METHODS: 298 blood oxygen saturation (SpO 2 ) signals from children ranging 0-13 years of age were recorded during overnight polysomnography (PSG). These recordings were divided into three severity groups according to the PSG-derived apnea hypopnea index (AHI): AHI < 5 events per hour (e/h), 5 ≤ AHI < 10 e/h, AHI ≥ 10 e/h...

Cleft lip and palate (CLP) is the most common congenital craniofacial abnormality. Obstructive sleep apnea syndrome (OSAS) is a highly prevalent but underdiagnosed disease and is frequently associated with craniofacial anomalies. There are few studies describing the sleep breathing pattern of children with CLP. This study sought to characterize the respiratory profile of 23 children with unilateral cleft lip and palate, aged 7-12 years, who had undergone cleft lip and nasal repair at age 3-4 months and palatoplasty at 12-15 months, with a particular focus on evaluating the presence of OSAS in children with CLP...

RATIONALE: Childhood sleep disordered breathing ranges in severity from primary snoring to obstructive sleep apnea and is associated with behavioral and neurocognitive deficits. It remains unknown why children with primary snoring, who do not experience peripheral oxygen desaturation or sleep fragmentation, experience similar daytime deficits as those with obstructive sleep apnea or why effects are age dependent. OBJECTIVE: To examine cerebral tissue oxygenation and oxygen extraction as an explanation for daytime deficits in children with primary snoring...
