Sleep apnea-hypopnea syndrome (SAHS) consists of recurrent episodes in which the airflow becomes limited during sleep, a consequence of anatomo-functional abnormalities of the upper airway (UA) that lead to its collapse. This leads to a reduction in oxyhemoglobin saturation (SaO2) and causes arousals from sleep. The symptoms of this syndrome include the sensation of not having been refreshed by...

Background: Studies have revealed a strong link between sleep-related breathing disorders and essential hypertension. However, the trends of sleep-disordered breathing in hypertensive patients have not been analyzed frequently. Methods: In this prospective, single-center and observational study, random patients with systemic essential hypertension, who were visiting GSVM Medical College, Kanpur...

The aim of the present study was to compare the clinical findings and polysomnography results obtained at public and private clinics in Brazil, the follow-up after diagnosis, and the therapeutic aspects related to continuous positive airway pressure. Patients who snore and who have obstructive sleep apnea were retrospectively divided into two groups, i.e., public clinic (N=307) and private clin...

An adenoidectomy is the surgical treat ment that consists in the removal of hypertrophied lymphatic tissue (Lushka’s pharyngeal tonsil), which blocks the rhinopharynx, behind the nose. Hypertrophy is the result of an abnormal development of the lymphatic follicles either from birth or as a result of repeated infections of the upper respiratory tract. Hypertrophy, in its turn, favors recurrent i...

Abstract Introduction The THN3 randomized, controlled trial of moderate to severe obstructive sleep apnea (OSA) showed that proximal (“targeted”) hypoglossal nerve stimulation (HGNS) safely improved sleep-disordered breathing (SDB) and quality life (QOL) through 11 months treatment. Outcomes subjects receiving active HGNS also surpassed those with inactive therapy 4 post-implant. Herein 3-year ...

AIM Gastroesophageal reflux disease (GERD) is a common disorder in the Western population, but detailed population-based data in China are limited. The aim of this study was to understand the epidemiology of symptomatic gastroesophageal reflux (SGER) in adults of Xi'an, a northwestern city of China, and to explore the potential risk factors of GERD. METHODS Symptoms suggestive of GERD, functi...

Associated With Obstructive Sleep Apnea Contribute to Development of Cardiovascular Disease in Patients With Obstructive Sleep Apnea Syndrome? To the Editor: In a recent issue of Circulation, Narkiewicz et al1 demonstrated that cardiovascular variability is altered in patients with obstructive sleep apnea (OSA). The authors concluded that abnormalities in cardiovascular variability might be imp...

INTRODUCTION The prevalence of snoring and sleep-disordered breathing (SDB) in young adults in Southeast Asian countries is unknown. We aim to determine the symptoms and prevalence of SDB in a university student population using a questionnaire survey followed by home sleep monitoring. METHODS The Sleep and Health Questionnaire (a modified version of the Specialized Centers of Research Sleep ...

Obstructive Sleep Apnea is increasingly seen as a common and important condition, contributing to sleep disturbance and consequential daytime sleepiness. This has potentially serious consequences for the individual, employers, and society as a whole. Apnea refers to short spells when breathing stops. In obstructive sleep apnea, the throat constricts during sleep, preventing breathing; the apnea...

Positive airway pressure (PAP) therapy is almost universally effective in treating obstructive sleep apnea. The biggest obstacle in treating obstructive sleep apnea is getting patients to use the PAP device. The term " adherence " is gaining favor over the term " compliance. " The definition of PAP adherence varies, but the generally accepted (and somewhat arbitrarily chosen) definition is Ն 4 ...
