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...

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...

Introduction: Children with cleft lip and/or palate are at increased risk of obstructive sleep apnea. The prevalence of obstructive sleep apnea in this population is unknown. The purpose of this study was to assess the frequency of obstructive symptoms and obstructive sleep apnea diagnosis in the cleft population. We hypothesized that obstructive symptoms present more frequently in children wit...

BACKGROUND Previous studies have suggested that the obstructive sleep apnea syndrome may be an important risk factor for stroke. It has not been determined, however, whether the syndrome is independently related to the risk of stroke or death from any cause after adjustment for other risk factors, including hypertension. METHODS In this observational cohort study, consecutive patients underwe...

Rhinitis can be divided into allergic and non-allergic rhinitis. Rhinitis, particularly allergic rhinitis, has been shown to be associated with obstructive sleep apnea; a condition characterized by repetitive upper airway obstruction during sleep. Allergic rhinitis increases the risk of developing obstructive sleep apnea by two major mechanisms: 1) increase in airway resistance due to higher na...

Sleep-related breathing disorders range from habitual snoring to severe obstructive sleep apnea syndrome. The prevalence of habitual snoring is high and up to 60 % depending on age, sex and body weight. However, in contrast to habitual snoring obstructive sleep apnea syndrome may be associated with medical complications. The prevalence of obstructive sleep apnea is 2 – 5 % of the adult populati...

OBJECTIVE Obstructive sleep apnea syndrome is characterized by repetitive obstruction of the upper airways, and it is a risk factor for cardiovascular diseases. There have been several studies demonstrating low levels of nitric oxide in patients with obstructive sleep apnea syndrome compared with healthy controls. In this study, we hypothesized that reduced nitric oxide levels would result in h...

BACKGROUND Prior studies suggest that obstructive sleep apnea may be associated with gastroesophageal reflux disease, a strong risk factor for Barrett's esophagus. The goals of this pilot case-control study were to determine whether Barrett's esophagus patients have an increased likelihood of obstructive sleep apnea and to determine whether nocturnal gastroesophageal reflux symptoms affect the ...

Masticatory and tongue muscle activity was examined polysomnographically in 14 patients with sleep apnea syndrome and six snorers. The all-night polysomnographic recordings included electromyograms (EMG) of the genioglossal, the masseter and the inferior head of the lateral pterygoid muscles, nasal airflow and thoracoabdominal respiratory effort. The apneas were defined and classified into thre...
