Obstructive sleep apnea in preschool-aged Japanese children - efficiency of screening using lateral neck radiography.

Conclusions The prevalence of obstructive sleep apnea (OSA) in preschool-aged children diagnosed by the International Classification of Sleep Disorders (ICSD) version 3 criteria was relatively higher than that diagnosed by ICSD-2. Although the assessment of the upper airway by lateral neck radiography was effective for detecting OSA in this age group, this assessment is not recommended for all children as a screening method because of parental concern related to radiation exposure. Objective This study investigated the prevalence of OSA and the screening capacity of lateral neck radiography in community-based preschool-aged children.

Type I Chiari malformation presenting central sleep apnea.

Sleep apnea is a rare but a well-known clinical feature of type I Chiari malformation. It may be obstructive or central in nature. Sleep apnea in patients with type I Chiari malformation rarely presents without accompanying neurological signs or symptoms.

Prevalence of obstructive sleep apnea syndrome in Japanese elementary school children aged 6-8 years.

Purpose: We aimed to determine the prevalence of and the risk factors for obstructive sleep apnea syndrome (OSAS) in Japanese children aged 6-8 years.

Methods: The parents of 202 children aged 6-8 years who attended a single elementary school in Shiga, Japan, were requested to complete the Child and Adolescent Sleep Checklist (CASC) and perform home Type 3 portable monitoring of their children. By using the CASC data and monitor recordings, we estimated the prevalence of pediatric OSAS with the help of different diagnostic criteria and identified the risk factors associated with OSAS.

A new modification of uvulopalatopharyngoplasty for the treatment of obstructive sleep apnea syndrome.

Objective: To evaluate objective and subjective improvement after applying a new surgical technique, two-piece palatopharyngoplasty (Two-P4), to the treatment of obstructive sleep apnea syndrome (OSAS).

Methods: Twenty-four patients with mild to severe OSAS underwent Two-P4 between January 2002 and November 2007. Polysomnography and Epworth Sleepiness Scale (ESS) score were used to evaluate surgical results.

Continuous positive air pressure treatment reduces serum advanced glycation end products in patients with obstructive sleep apnoea syndrome: a pilot study.

Nasal continuous positive air pressure (nCPAP) treatment may favourably affect serum levels of advanced glycation end products (AGEs) in patients with obstructive sleep apnoea syndrome (OSAS). At baseline, OSAS patients had significantly higher levels of AGEs than controls. Six months after nCPAP initiation, AGEs decreased significantly.
