AIM Sleep disordered breathing is a common problem in childhood that encompasses a spectrum of disorders extending from primary snoring to obstructive sleep apnea. This study aims to investigate the results of children undergoing evaluation with polysomnography in the sleep laboratory of a tertiary care hospital. MATERIAL AND METHODS Demographic and clinical features as well as sleep associat...

STUDY OBJECTIVES The primary aim of this study was to determine the prevalence of positional obstructive sleep apnea using a functional definition. Positional sleep apnea was defined as a total apnea-hypopnea index (AHI) > or = 5 with a > 50% reduction in the AHI between the supine and nonsupine postures, and an AHI that normalizes (AHI < 5) in the nonsupine posture. A secondary aim was to dete...

BACKGROUND Sleep apnea is common in patients with atrial fibrillation, but the effect of the cardioversion of atrial fibrillation to sinus rhythm on central and obstructive apneas is mainly unknown. The primary aim of the study was to analyze the association between cardioversion of atrial fibrillation and sleep apneas, to investigate whether obstructive or central sleep apneas are reduced foll...

OBJECTIVE Obstructive sleep apnea is frequent during the acute phase of stroke, and it is associated with poorer outcomes. A well-established relationship between supine sleep and obstructive sleep apnea severity exists in non-stroke patients. This study investigated the frequency of supine sleep and positional obstructive sleep apnea in patients with ischemic or hemorrhagic stroke. METHODS P...

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....

A randomized, controlled study of a mandibular advancement splint for obstructive sleep apnea. Efficacy of positive airway pressure and oral appliance in mild to moderate obstructive sleep apnea. advancement devices in 630 men and women with obstructive sleep apnea and snoring: tolerability and predictors of treatment success. Assessment of upper airway dynamics in awake sleep apnea patients wi...

Over the past 20 years, increasing data have accumulated underscoring the public health importance of sleep apnea with growing evidence of its high prevalence and myriad clinical manifestations. This condition, rarely diagnosed in the past, had been considered to occur predominantly as a manifestation of morbid obesity and considered to affect almost exclusively middle-aged men. Sleepiness and ...

Heart failure is an increasingly common public health problem that is strongly linked to both central and obstructive sleep apnea, collectively referred to as sleep-disordered breathing. Much attention has been given to the deleterious effects of sleep-disordered breathing on the failing heart and potential mechanisms by which treatment of sleep-disordered breathing may result in improved cardi...

STUDY OBJECTIVES We conducted the present study to determine whether psychiatric disorders are commonly associated with sleep apnea in Veterans Health Administration beneficiaries. METHOD The Veterans Health Administration maintains several centralized databases containing healthcare data for more than 4 million veterans. We reviewed data from 1998 to 2001 and identified patient records havin...

it has been documented that nearly 25-30% of automobile collisions are potentially associated with driving fatigue. we have little control over sleep propensity when chronically sleep-deprived or suffer from an underlying sleep insufficiency. drowsy driving is not only a personal but also a public hazard and commercial drivers with alternate shifts are critically at risk. people on monotonous d...
