Introduction:The overlap syndrome, consisting ofobstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructvie pulmonary disease (COPD) is a major problem in COPD patients. OSHAS corresponds to the likelihood of systemic hypertension.The present study was aimed to evaluate the association between apnea-hypopnea index and diastolic blood presssure (DBP) in overlap  patients. Materials...

background and objective : obstructive sleep apnea (osa) syndrome is a kind of sleep-related disorder with complex features and may lead to daytime sleepiness. this study aimed to find the differences between smokers and non-smokers regarding the parameters of polysomnography. materials and methods : this was a cross-sectional study conducted on consecutive patients referred to a sleep lab to p...

introduction: chronic obstructive pulmonary disease (copd) patients are at increased risk of sleep-disorders. the concomitant occurrence of copd and obstructive sleep apnea hypopnea syndrome (osahs) is named overlap syndrome. this study aimed to evaluate the severity of osahs in overlap syndrome patients.materials & methods: this cross-sectional study was conducted on adult patients with forced...

background and objective : obstructive sleep apnea (osa) through hypoxia and reoxygenation periods leads to oxidative stress, endothelial dysfunction, and activation of inflammatory cycles, which eventually may cause disorder in vasa nervorum, and peripheral neuropathy in hearing pathway. in this study, we aimed to evaluate the effect of severe sleep apnea on hearing function. materials and met...

OBJECTIVE To examine whether circulating leptin levels correlate with the severity of disease in patients with obstructive sleep apnea. DESIGN Prospective nonrandomized study. SETTING Referral sleep laboratory for patients with sleep-disordered breathing and biochemistry laboratory. Patients Thirty-two subjects (mean +/- SD age, 47 +/- 12 years) who were referred for suspected sleep apnea u...

STUDY OBJECTIVE To evaluate the tolerability and to find predictors of treatment success for an individually adjusted, one-piece mandibular advancement device in patients with snoring and obstructive sleep apnea. DESIGN Prospective study. SETTING Departments of Respiratory Medicine and Orthodontics, Umeå University. PATIENTS Six hundred nineteen of 630 patients (98%), who consecutively re...

AIM Sleep disordered breathing is a common problem in childhood that encompasses a spectrum of disorders extending from primary snoring to obstructive sleep apnea. This study aims to investigate the results of children undergoing evaluation with polysomnography in the sleep laboratory of a tertiary care hospital. MATERIAL AND METHODS Demographic and clinical features as well as sleep associat...

OBJECTIVE Altitude can affect the diagnostic accuracy of portable monitors used to diagnose suspected obstructive sleep apnea syndrome on the basis of oxygen desaturation measurements. The aim of this study was to determine agreement between the desaturation index measured by oximetry and the apnea-hypopnea index measured by polysomnography in Mexico City (2240 m above sea level). We also wishe...
