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)
OBJECTIVE To investigate the relative contribution of various risk factors to the surgical outcome of adenotonsillectomy for obstructive sleep apnea syndrome in children. STUDY DESIGN Children (n = 110; mean age, 6.4 +/- 3.9 years) underwent two polysomnographic evaluations before and after adenotonsillectomy. In addition, 22 control children were(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)
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)
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)
OBJECTIVES To identify the prevalence of long-term sleep disturbances in children successfully treated for central nervous system tumors by use of subjective and objective tools. STUDY DESIGN Children diagnosed and treated for central nervous system tumors and age-matched control subjects were studied. Information on demographics, tumor type, location,(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 AND BACKGROUND Snoring is common among pregnant women and early reports suggest that it may bear a risk to the fetus. Increased fetal erythropoiesis manifested by elevated circulating nucleated red blood cells (nRBCs) has been found in complicated pregnancies involving fetal hypoxia. Both erythropoietin (EPO) and interleukin-6 (IL-6) mediate(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)
BACKGROUND Modafinil is an alerting agent approved for the treatment of narcolepsy in adults. There are no studies examining the long-term effects and safety profile of modafinil in children with excessive daytime somnolence (EDS). OBJECTIVES To determine the effects of modafinil on clinical manifestations of narcolepsy and idiopathic hypersomnia. (More)
