background: sleep apnea is temporary cessation or absence of breathing during sleep. significant increase in blood pressure is clinically seen in apneic episodes. the aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (naion) in a case control study. methods: nineteen naion patients (9 men and 10 women) and 31 age and sex...

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...

OBJECTIVE To investigate the surgical outcomes of a modified uvulopalatopharyngoplasty-extended uvulopalatal flap in the treatment of obstructive sleep apnea. MATERIAL AND METHODS Thirty-three consecutive patients with obstructive sleep apnea underwent extended uvulopalatal flap that consisted of bilateral tonsillectomy, dissection and removal of submucosal adipose tissue of the soft palate a...

Abstract Background Obstructive sleep apnea (OSA) is a risk factor for development of atrial fibrillation (AF). Recent pacemakers have specific algorithms detecting OSA based on impedance measurement. Purpose The aim was to determine the burden AF in patients with high respiratory disturbance index (RDI). It also intended if onset continuous positive airway pressure (CPAP) reduced burden. Metho...

Diagnosis of obstructive sleep apnoea syndrome (OSAS) is usually performed during overnight polysomnography in the sleep laboratory. In an attempt to simplify the diagnostic strategy, we compared an ambulatory device, CID 102, with polysomnography during the same night in the laboratory in 50 consecutive patients referred for polysomnography. The CID 102 device monitors oxygen saturation, heart...

BACKGROUND Disturbed sleep and nocturnal altered breathing are related to disturbances of glucose metabolism. The present uncontrolled observational study explores the role of these factors on the variability of fasting glycemia. METHODS The number and duration of nocturnal awakenings and the fasting glycemia of 97 patients with type 2 diabetes treated with diet, metformin, or gliptins were r...

STUDY OBJECTIVES To estimate the extent to which genetic factors contribute to the variation in several indices of sleep-disordered breathing in elderly male twins. DESIGN AND SETTING A biometric genetic study based on data from unattended Edentrace recordings in a sample of elderly male twins. PARTICIPANTS 122 World War II male veteran twin pairs, including 68 monozygotic pairs aged 78.9 (...

STUDY OBJECTIVES The results of small studies have suggested that a nasal-cannula pressure transducer has a higher sensitivity than a thermistor in detecting hypopneas and diagnosing sleep-disordered breathing in both adults and children. We compared a thermistor alone, and in conjunction with a pressure transducer, for detection of sleep-disordered breathing in children during in-home polysomn...

OBJECTIVES/HYPOTHESIS The effect of the Pillar implant on mild sleep-disordered breathing (SDB) has been assessed in various studies. However, most of these were conducted among a non-Asian population at a single institution. Therefore, the aim of this study was to prospectively evaluate the efficacy of the Pillar implant in Asian patients with simple snoring and mild obstructive sleep apnea (O...
