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...

Rhinitis can be divided into allergic and non-allergic rhinitis. Rhinitis, particularly allergic rhinitis, has been shown to be associated with obstructive sleep apnea; a condition characterized by repetitive upper airway obstruction during sleep. Allergic rhinitis increases the risk of developing obstructive sleep apnea by two major mechanisms: 1) increase in airway resistance due to higher na...

OBJECTIVE Obstructive sleep apnea is frequent during the acute phase of stroke, and it is associated with poorer outcomes. A well-established relationship between supine sleep and obstructive sleep apnea severity exists in non-stroke patients. This study investigated the frequency of supine sleep and positional obstructive sleep apnea in patients with ischemic or hemorrhagic stroke. METHODS P...

STUDY OBJECTIVES Obstructive sleep apnea is common among patients with atrial fibrillation, but the prevalence and risk factors for atrial fibrillation among patients who are being investigated on suspicion of sleep apnea are not well known. The aim of the study was to estimate the prevalence of atrial fibrillation among patients investigated for suspected obstructive sleep apnea and to identif...

No agreement exists as to the mechanisms responsible for the sympathetic hyperactivity characterizing human obesity, which has been ascribed recently to a chemoreflex stimulation brought about by obstructive sleep apnea rather than to an increase in body weight, per se. In 86 middle-age normotensive subjects classified according to body mass index, waist-to-hip ratio, and apnea/hypopnea index (...

background and objective: failure in diagnosis and treatment of sleep apnea in children lead to physical and mental growth retardation, cardiopulmonary, and/or behavioral disorders. this study was aimed to evaluate polysomnographic (psg) and clinical findings of sleep apnea in children referred to a sleep clinic in qazvin, iran. materials and methods: this cross-sectional study was conducted am...

BACKGROUND The study was performed in order to determine the risk factors for difficult tracheal intubation in obstructive sleep apnea patients. METHODS For 115 male patients with obstructive sleep apnea syndrome and who were undergoing palatal muscle resection (PMR), we investigated the correlation between their age, height, weight, body mass index (BMI), their Epworth Sleepiness Scale (ESS)...

Sleep-related breathing disorders range from habitual snoring to severe obstructive sleep apnea syndrome. The prevalence of habitual snoring is high and up to 60 % depending on age, sex and body weight. However, in contrast to habitual snoring obstructive sleep apnea syndrome may be associated with medical complications. The prevalence of obstructive sleep apnea is 2 – 5 % of the adult populati...

1. Review the clear relationship between obstructive sleep apnea and hypertension. 2. Discuss the cardiac consequences of sleep apnea, including coronary heart disease, heart failure, and different dysrhythmias. 3. Understand that sleep disorders beyond obstructive sleep apnea, such as insufficient sleep itself, may have an impact on the cardiovascular system. 4. Appreciate the potential benefi...

INTRODUCTION Sleep movement disorders includes mainly periodic limb movement and others. The more frequent breathing disorders are: obstructive sleep apnea-hypopnea syndrome and primary snoring. OBJECTIVE To compare sleep architecture in periodic limb movements and breathing disorders of different severity, and weight their interactions. METHODS We compared sleep architecture in 160 patient...
