Factors associated with referrals for obstructive sleep apnea evaluation among community physicians.
This study assessed knowledge and attitudes toward obstructive sleep apnea (OSA) among community physicians and explored factors that are associated with referrals for OSA evaluation. ⋯ Independent of physicians' knowledge and attitudes toward obstructive sleep apnea, the likelihood of making a referral for obstructive sleep apnea evaluation was influenced by whether patients inquired about the condition.

Obstructive sleep symptoms are common in children with craniofacial malformations (CFM). However objective data about obstructive sleep apnea (OSA) is still limited. The aims of this study were to investigate the frequency of OSA in symptomatic children with CFM and to determine improvement in severity of OSA after treatment. ⋯ The vast majority of children with CFM referred for OSA evaluation are found to have objective evidence of OSA and a quarter of children have moderate-to-severe OSA. It is likely that many children with underlying OSA are not identified and referred for evaluation. Residual OSA after treatment is common in children with CFM.

Overnight rostral fluid shift from the legs to the neck may narrow the pharynx and contribute to obstructive sleep apnea (OSA) pathogenesis. We hypothesized that night-to-night changes in the apnea-hypopnea index (AHI) would be associated with changes in overnight rostral fluid shift. ⋯ Intra-individual variability in OSA severity may be partly explained by day-to-day changes in evening leg fluid volume and overnight rostral fluid shift, which may be most important in the pathogenesis of OSA during NREM and supine sleep.
