Obstructive sleep apnea syndrome (OSAS) is char­ acterized by repeated partial or complete collapse of the pharynx during sleep, which results in apnea or hypopnea, associated with oxygen desaturation and arousal from sleep. OSAS is associated with meta­ bolic syndrome, cardiovascular diseases, and neu­ ropsychological sequelae. In addition, traffic and work-related accidents are frequently att...

OBJECTIVE To investigate the prevalence of obstructive sleep apnea in patients with ischemic stroke and to evaluate the effectiveness of nasal continuous positive airway pressure treatment. METHODS Overnight polysomnography was performed by a computerized system in 19 subjects with ischemic stroke. Patients with an apnea-hypopnea index > or = 5 were considered to have obstructive sleep apnea....

OBJECTIVE Obstructive sleep apnea syndrome is associated with cardiovascular diseases and thromboembolic events. The mean platelet volume (MPV) is a predictor of cardiovascular thromboembolic events. The aim of the present study is to investigate the association between the MPV and disease severity in patients with obstructive sleep apnea syndrome. METHODS We prospectively included 194 obstru...

INTRODUCTION Sleep movement disorders includes mainly periodic limb movement and others. The more frequent breathing disorders are: obstructive sleep apnea-hypopnea syndrome and primary snoring. OBJECTIVE To compare sleep architecture in periodic limb movements and breathing disorders of different severity, and weight their interactions. METHODS We compared sleep architecture in 160 patient...

BACKGROUND In men with heart failure, nocturnal rostral fluid shift is associated with an overnight increase in the neck circumference (NC) and with severity of obstructive sleep apnea. Because the prevalence of obstructive sleep apnea is lower in women than in men with heart failure, we hypothesized that less fluid would shift into the neck in association with less severe obstructive sleep apn...

OBJECTIVES/HYPOTHESIS To verify the reliability and validity of automated scoring and compare it to that of manual scoring for diagnosing obstructive sleep apnea using an Embletta X100 level 2 portable device. STUDY DESIGN Retrospective study. METHODS A total of 116 patients with suspected obstructive sleep apnea who had successfully received portable polysomnography with the Embletta X100 ...

Current treatment options are successful in 40% to 60% of children with persistent obstructive sleep apnea after adenotonsillectomy. Residual obstruction assessments are largely subjective and do not clearly define multilevel obstruction. We endeavor to use computational fluid dynamics to perform virtual surgery and assess airflow changes in patients with Down syndrome and persistent obstructiv...

OBSTRUCTIVE SLEEP APNEA (OSA) IS A HIGHLY PREVALENT SYNDROME THAT IS ASSOCIATED WITH SUBSTANTIAL MORBIDITY AND INCREASED MORTALITY.1-10 Positive airway pressure (PAP) is the most uniformly effective therapy, and to date this is the only intervention for OSA shown to have a favorable impact on both cardiovascular and neurobehavioral morbidities.1,2,6 However, approximately 25-50% of patients wit...

BACKGROUND Distraction advancement has been advocated for treatment of obstructive sleep apnea associated with congenital midface hypoplasia. The purpose of this study was to relate changes in maxillary position to changes in obstructive sleep apnea measures on polysomnography in a consecutive series of patients. METHODS Among 26 syndromic pediatric patients undergoing Le Fort III distraction...
