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...

PURPOSE: Cross-sectional studies have documented the co-occurrence of obstructive sleep apnea (hereafter, sleep apnea) with glucose intolerance, insulin resistance, and type 2 diabetes mellitus (hereafter, diabetes). It has not been determined, however, whether sleep apnea is independently associated with the subsequent development of diabetes, accounting for established risk factors. METHODS: ...

STUDY OBJECTIVES To determine whether drivers with sleep apnea are at increased risk of motor vehicle crash; whether disease severity, daytime sleepiness, or both disease severity and daytime sleepiness affect this risk, and whether treatment of sleep apnea reduces crash risk. DESIGN Systematic review of published literature. SETTING N/A. PATIENTS/PARTICIPANTS Patients with sleep apnea. ...

RATIONALE Opioids have become part of contemporary treatment in the management of chronic pain. However, chronic use of opioids has been associated with high prevalence of sleep apnea which could contribute to morbidity and mortality of such patients. OBJECTIVES The main aim of this study was to treat sleep apnea in patients on chronic opioids. METHODS Five consecutive patients who were ref...

Background: Sleep apnea is temporary cessation or absence of breathing during sleep. Significant increase in blood pressure is clinically seen in apneic episodes. The aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (NAION) in a case control study. Methods: Nineteen NAION patients (9 men and 10 women) and 31 age and ...

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...

PURPOSE To evaluate intraocular pressure (IOP) changes during nocturnal sleep in patients with obstructive sleep apnea syndrome (OSAS) using a contact lens sensor (CLS). METHODS This was a prospective cohort study. Seven OSAS patients who had no ocular diseases except mild cataract were enrolled. Each subject underwent CLS-based continuous IOP monitoring on one eye simultaneously with overnig...

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...

Obstructive sleep apnea is a chronic illness with increasing prevalence. In addition to associated cardiovascular comorbidities, obstructive sleep apnea syndrome has been linked to poor quality of life, occupational accidents, and motor vehicle crashes secondary to excessive daytime sleepiness. Although continuous positive airway pressure is the gold standard for sleep apnea treatment, its effe...
