The aim of this preliminary work is to determine an easy method to diagnose "buccal breather" children and "nasal breather" children. Then, to establish a possible connection with the syndrome of obstructive sleep apnea. 22 children agreed to participate. Clinical, orthophonic, orthodontic, postural and polysomnographical exams have been carried out. The proposed clinical exam turns out to be a...

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...

UNLABELLED Anesthesia and surgery both affect the architecture of sleep. Aside from the postoperative effects of anesthesia and surgery, sleep deprivation and fragmentation have been shown to produce apneas or desaturations even in patients without presumed sleep apnea. Recent epidemiologic data have placed the prevalence of obstructive sleep apnea syndrome (OSAS) at about 5% among Western coun...

S leep apnea is defined as a sleep disorder with frequent episodes of upper-airway obstruction resulting in hemoglobin oxygen desaturation. The disorder is characterized by periods of breathing cessation (apnea) and periods of reduced breathing (hypopnea). Sleep apnea increases morbidity and mortality, thus making it a condition worthy of investigation.1 Sleep apnea is typically categorized as ...

The review analyzes data from domestic and foreign sources focusing on the current state of a common problem obstructive sleep apnea syndrome. article describes main mechanisms development possible relationships between cardiovascular diseases, risk factors in patients, sleep-related breathing disorder symptom-complex. provides status update continuous positive airway pressure (CPAP) therapy co...

Obstructive sleep apnea is a very common disease and is associated with an increased risk of cardiovascular disease, cardiac arrhythmia, and stroke. Arterial stiffness is an emerging risk factor and may be involved in the cardiovascular complications of obstructive sleep apnea. The purpose of this review was to demonstrate the correlation between arterial stiffness and obstructive sleep apnea. ...

OBJECTIVE Obstructive sleep apnea is characterized by increased upper airway collapsibility during sleep. The present study investigated the use of the negative expiratory pressure test as a method to rule out obstructive sleep apnea. METHODS Flow limitation was evaluated in 155 subjects. All subjects underwent a diurnal negative expiratory pressure test and a nocturnal sleep study. The sever...

Intermittent hypoxia, a powerful and unique stimulus, leads to physiologic changes that are distinct from those associated with either single or continuous hypoxic exposure. There is an accumulating body of evidence that the neurocognitive, inflammatory and cardiovascular symptoms that characterize the syndrome of obstructive sleep apnea are linked to the stimulus of intermittent hypoxia. In ad...
