STUDY OBJECTIVES Excessive daytime sleepiness (EDS), as measured by objective criteria, is infrequent in snoring children despite a high prevalence of EDS-related behavioral manifestations. We hypothesized that sleep architecture and arousal indexes may be altered relative to the severity of sleep-disordered breathing (SDB). DESIGN Retrospective and(More)
OBJECTIVE Adenotonsillar hypertrophy (ATH) is the leading cause for obstructive sleep apnea syndrome (OSAS) in children. The peak age for adenoid and tonsillar hypertrophy and related OSAS is 3-6 years. It has been suggested that OSAS due to ATH is extremely rare in infants. The purpose of the present study was to delineate OSAS due to ATH in infants. (More)
OBJECTIVE Sleep-disordered breathing (SDB) is associated with insulin resistance and dyslipidemia in adults and in obese children. However, the prevalence of such metabolic abnormalities among snoring children is unknown. This study was done to prospectively assess the relative contribution of SDB and obesity to metabolic disturbances in a large cohort of(More)
Obstructive sleep apnea (OSA) is a major public health problem affecting approximately 2% to 3% of children. However, snoring, the cardinal symptom of OSA, affects at least 5-fold more children, such that evaluation by overnight polysomnography (ONP) is required for the diagnosis. ONP is laborious, expensive, and relatively unavailable to children.(More)
BACKGROUND Sleep disordered breathing in children is associated with severity-dependent increases in excessive daytime sleepiness (EDS). TNF-alpha is an inflammatory cytokine that has been implicated in EDS. Since, at any given level of apnea-hypopnea index, there is significant variability in EDS, we hypothesized that morning tumor necrosis factor(More)
The objective of this study was to determine the normal range of nocturnal urinary excretion of the major melatonin metabolite, 6-sulfatoxymelatonin (6SMT) in a large sample of healthy full-term infants (8 and 16 wk old) and assess whether the endogenous production of melatonin changes with season. 6SMT was assessed in urine samples extracted from(More)
OBJECTIVE Behavioral insomnia and feeding difficulties are 2 prevalent conditions in healthy young children. Despite similarities in nature, etiology, prevalence, and age distribution, the association between these 2 common disorders in young children has not been examined thus far. PATIENTS AND METHODS Children aged 6 to 36 months with either behavioral(More)
OBJECTIVE Sleep-disordered breathing (SDB) is a common disorder associated with substantial morbidity that occurs in otherwise healthy children. Atopy, asthma, and viral upper respiratory tract infections are known risk factors for pediatric SDB that exhibit seasonal variability. The aim of our study was to investigate the effect of seasonality on SDB(More)
STUDY OBJECTIVES Polysomnography is important in the evaluation of children and adolescents with sleep-disordered breathing. Adult criteria for obstructive sleep apnea have been shown to be inapplicable to children. Nevertheless, very little data are available regarding normal respiratory parameters during sleep in healthy children and adolescents. The(More)
INTRODUCTION Levels of C-reactive protein (CRP), an important serum marker of inflammation with major implications for cardiovascular morbidity and atherogenesis, are elevated among adult patients with sleep-disordered breathing (SDB). We hypothesized that elevated CRP plasma levels would also be present among children with SDB. METHODS Eighty-one(More)
