The efficacy of adenotonsillectomy for relieving obstructive sleep apnoea symptoms in children has been firmly established, but its precise effects on cardiorespiratory control are poorly understood. In 375 children enrolled in the Childhood Adenotonsillectomy Trial, randomised to undergo either adenotonsillectomy (n=194) or a strategy of watching waiting (n=181), respiratory rate, respiratory sinus arrhythmia and heart rate were analysed during quiet, non-apnoeic and non-hypopnoeic breathing throughout sleep at baseline and at 7 months using overnight polysomnography...

The sleep clinical record (SCR) may be a valid method for detecting children with obstructive sleep apnoea (OSA). This study aimed to evaluate whether there were differences in SCR depending on age and to identify the possible risk factors for OSA development. We enrolled children with sleep disordered breathing between 2013 and 2015, and divided them according to age into preschool- and school-age groups. All patients underwent SCR and polysomnography. OSA was detected in 81.1% and 83.6% of preschool- and school-age groups, respectively...

OBJECTIVES: Caregivers describe significant sleep disturbances in the vast majority of children and adolescents, which is diagnosed as fetal alcohol spectrum disorders (FASD), but objective data on sleep disorders in this population are almost completely lacking. Animal models suggest that intrauterine alcohol exposure may disrupt sleep wake patterns, cause sleep fragmentation, and specifically affect the suprachiasmatic nucleus, thus disrupting melatonin secretion. The objective of this pioneering study was to evaluate sleep and melatonin abnormalities in children with FASD using objective, gold-standard measures...

Only a handful of studies, primarily in clinical samples, have reported an association between obesity, inflammation, and obstructive sleep apnea (OSA) in children and adolescents. No studies, however, have examined the pathogenetic link between visceral adiposity, systemic inflammation, and incident OSA in a large general population sample using objective measures of sleep and body fat. Adolescents (n=392; mean age 17.0±2.2y, 54.0% male) from the Penn State Child Cohort (PSCC) underwent 9-hour overnight polysomnography; a DXA scan to assess body fat distribution; and a single fasting blood draw for the assessment of plasma interleukin-6 (IL-6), IL-6 soluble receptor (IL-6 sR), tumor necrosis factor alpha (TNFα), tumor necrosis factor receptor 1A (TNFR1), C-reactive protein (CRP), leptin, and adiponectin levels via ELISA...

INTRODUCTION: Both sleep-disordered breathing (SDB) and high blood pressure (BP) occur more frequently among obese children than among normal weight children, and this may be due to endothelial dysfunction and worsened arterial stiffness. The aim of this study was to evaluate the possible association between SDB and BP, and the possible role of endothelial function and local and systemic arterial stiffness in a sample of obese children asymptomatic for sleep disturbances. MATERIALS AND METHODS: Thirty-nine obese children were included in the study...

BACKGROUND: Polysomnography (PSG) is the gold standard for sleep bruxism (SB) diagnosis. PSG/SB children's criteria are not available; thus, parental-report SB is widely used. AIM: Assessing the diagnostic accuracy of parental report of sleep tooth grinding (STG) with a PSG/SB diagnosis in children, adopting adult criteria. DESIGN: Thirty-seven children from clinics of Universidad CES were included. Parents filled the Children's Sleep Habits Questionnaire (CSHQ) assessing the single-observation report - CSHQ - of STG with a No/Yes answer and five ordinal answers...

It is increasingly clear that seminal sleep-affective relationships begin to take root in childhood, yet studies exploring how nighttime sleep characteristics relate to daytime affective symptoms, both in clinical and healthy populations of children, are lacking. The current study sought to explore these relationships by investigating whether trait-like and/or daily reports of affective and somatic symptoms of children with generalized anxiety disorder and matched controls relate to sleep architecture. Sixty-six children (ages 7-11; 54...

Adenotonsillectomy is recommended for children who need surgery for obstructive sleep apnea syndrome (OSAS). Overnight, polysomnography (PSG) is suggested for post-surgery follow-up, but this diagnostic technique is time consuming and inconvenient. Desaturation index (DI) has been reported as a good tool for predicting both the presence and severity of OSAS in children. The purpose of this study was to determine the usefulness of the DI for post-surgery follow-up of children with OSAS. This retrospective study enrolled 42 children, aged 3-12 years, who were snorers diagnosed with OSAS by overnight PSG and who underwent an adenotonsillectomy...
