Increased nasal airflow resistance (NAR) may contribute to the pathophysiology of obstructive sleep apnoea syndrome (OSAS) but studies investigating the effects of relieving nasal obstruction in OSAS have produced differing results. There are no reports of intranasal corticosteroid therapy in adult OSAS patients with reversible nasal obstruction.

Habitually snoring children are at risk of manifesting disease-related problems even if their sleep studies are overall within normal limits.

Two sources of information (parent-reported sleep diaries and actigraph records) were used to investigate how toddler sleep characteristics (bed time/sleep onset, wake time/sleep offset, total nighttime sleep, and total sleep time) are related to sleep problems and temperament. There were 64 toddler participants in the study. Consistent with studies of older children, parent reports differed from actigraph-based records.

There are limited data on the night-to-night variability of childhood sleep-related disordered breathing (SDB). We aim to assess for the presence of first-night effect (FNE) and to examine whether a single-night sleep study is adequate in the assessment of childhood SDB. In a case-control study investigating whether obesity is a risk factor for childhood SDB, the night-to-night variability of sleep and respiratory variables were studied.

This survey was conducted to examine the prevalence of sleep disorders in 2- to 12-year-old children in the Beijing area of China.
