Moderately accurate, depending on which tool you use. Questionnaires, physical examination, and clinical prediction rules estimate the pretest probability of obstructive sleep apnea hypopnea syndrome (OSAHS), but are not specific enough to make the diagnosis. The Epworth Sleepiness Scale is a reliable measure of daytime sleepiness. The Berlin Questionnaire, Mallampati score, and truncal obesity...

BACKGROUND Breathing-related sleep disorders cover several conditions (isolated snoring, UARS - upper airway resistance syndrome, obstructive sleep apnea, hypopnea, obesity hypoventilation syndrome) characterized by a variety of symptoms and complex etiology. The conditions can be successfully treated in most cases. Excessive body mass is a factor increasing the probability of the disorders. In...

BACKGROUND AND PURPOSE Convincing evidence of a causal relationship between sleep apnea and stroke has been shown recently in several prospective, well-designed studies. However, these studies have focused on middle-aged people, excluding the elderly population from analysis. To investigate whether sleep apnea represents an independent risk factor in this population, we performed a prospective ...

Autonomic dysfunction is recognized to contribute to cardiovascular consequences in obstructive sleep apnea/hypopnea syndrome (OSAHS) patients who present predominant cardiovascular sympathetic activity that persists during wakefulness. Here, we examined 1) the factors that influence sympathetic cardiac modulation in response to apneas/hypopneas; and 2) the influence of autonomic activity durin...

Background: The mechanisms associated with the cardiovascular consequences of obstructive sleep apnea include abrupt changes in autonomic tone, which can trigger cardiac arrhythmias. The authors hypothesized that nocturnal cardiac arrhythmia occurs more frequently in patients with obstructive sleep apnea. Objective: To analyze the relationship between obstructive sleep apnea and abnormal heart ...

OBJECTIVE The aim of the present study was to determine the short-term efficacy of treatment for snoring and obstructive sleep apnea-hypopnea syndrome (OSAHS) using a mandibular advancement splint. METHODS The sample comprised 20 patients (13 men and 7 women; mean age = 48 years; mean body mass index = 27.07) with OSAHS. Polysomnograms were performed before and 60 days after mandibular advanc...

OBJECTIVES The present retrospective study analyzes sagittal cephalometric changes in patients affected by obstructive sleep apnea syndrome submitted to maxillomandubular advancement. MATERIAL AND METHODS 15 adult sleep apnea syndrome (OSAS) patients diagnosed by polysomnography (PSG) and treated with maxillomandubular advancement (MMA) were included in this study. Pre- (T1) and postsurgical ...

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 ...
