background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...

overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (copd) and obstructive sleep apnea (osa), was first defined by flenley. although it can refer to concomitant occurrence of any of the pulmonary diseases and osa, overlap syndrome is commonly considered as the coexistence of osa and copd. this disease has unique adverse health consequences distinct from ...

conclusions we assessed polysomnographic parameters of ahi, odi, laso2 and mean nocturnal spo2 levels, which are especially important in the association between nafld and osas. we think that it is necessary to be attentive regarding nafld development and progression in patients with osa whose nocturnal hypoxia is severe. patients and methods in this study, between december 2011 and december 201...

OBJECTIVES This study evaluated the effect of Continuous Positive Airway Pressure treatment on oxidative stress parameters and the quality of life of elderly patients with obstructive sleep apnea syndrome. METHODS In total, 30 obstructive sleep apnea syndrome patients and 27 subjects without obstructive sleep apnea syndrome were included in this study. Both groups underwent quality of life an...

BACKGROUND AND PURPOSE Epidemiological studies have suggested a pathophysiological link between sleep apnea syndrome and cerebrovascular diseases. The mechanism by which sleep disturbance can affect the predisposition to developing stroke is not clear. The aim of this study was to investigate whether patients with obstructive sleep apnea syndrome have an increase in atherosclerosis indicators a...

Excessive daytime sleepiness is one of the most common sleep-related patient symptoms, and it affects an estimated 20 percent of the population. Persons with excessive daytime sleepiness are at risk of motor vehicle and work-related incidents, and have poorer health than comparable adults. The most common causes of excessive daytime sleepiness are sleep deprivation, obstructive sleep apnea, and...

Sleep disorders are common during the clinical course of the main neurodegenerative diseases. Among these disorders, obstructive sleep apnea has been extensively studied in the last decade and recent knowledge regarding its relationship with the neurodegenerative process points a bidirectional relationship. Neurodegenerative diseases can lead to functional changes in the respiratory system that...

Obesity is associated with obstructive sleep apnea in the adult and pediatric population. The aim of our study was to assess the association between increasing body mass index on the severity of obstructive sleep apnea in children. We reviewed retrospectively 740 children with symptoms suggestive of obstructive sleep apnea who underwent a sleep study at an inner city university hospital. Obstru...

STUDY OBJECTIVES Some patients with apparent obstructive sleep apnea hypopnea syndrome (OSAHS) have elimination of obstructive events but emergence of problematic central apneas or Cheyne-Stokes breathing pattern. Patients with this sleep-disordered breathing problem, which for the sake of study we call the "complex sleep apnea syndrome," are not well characterized. We sought to determine the p...
