Comparative Study
Current hypopnea scoring criteria underscore pediatric sleep disordered breathing.
This is a retrospective study comparing 2007 American Academy of Sleep Medicine (AASM) pediatric scoring criteria and Stanford scoring criteria of pediatric polysomnograms to characterize the impact different scoring systems have upon the diagnosis of sleep disordered breathing in children. ⋯ The AASM scoring criteria classified 19% of subjects as having OSA while the Stanford criteria diagnosed 99% of the subjects with OSA who were referred for evaluation of suspected sleep disordered breathing. The primary factor differentiating the AASM and Stanford criteria was the scoring of hypopneas. The AASM definition of hypopnea may be detrimental to the recognition of SDB in children.

The prevalence of childhood sleep bruxism (SB) varied from 5% to 46% among various studies. In addition to local facial and dental adverse consequences, accumulating evidence suggests that childhood SB could be associated with comorbid sleep and systemic neurobehavioral disturbances. This study attempted to investigate the prevalence and clinical correlates of SB in a large community sample. ⋯ Almost 6% of Hong Kong primary schoolchildren suffered from frequent SB. The condition was most prevalent among young boys. SB was found to be associated with a variety of medical conditions, neuropsychiatric sequelae, and comorbid sleep conditions, especially sleep talking and sleep related breathing problems. Further prospective studies will need to clarify the longitudinal course of childhood SB and its response to treatment.
