OBJECTIVES/HYPOTHESIS To determine if supraglottoplasty (SGP) is effective in reversing abnormal respiratory parameters in children with laryngomalacia and obstructive sleep apnea (OSA). STUDY DESIGN Retrospective case series at a tertiary referral children's hospital. METHODS Ten patients with laryngomalacia and OSA as documented by polysomnography underwent SGP between 2005 and 2007. Data...

BACKGROUND Many patients undergoing bariatric surgery have severe comorbidities, including obstructive sleep apnea (OSA). We suspected that sleep apnea was underdiagnosed in our study population. METHODS A retrospective chart review of our bariatric database was conducted comparing OSA evaluation based on clinical parameters (Era 1) with mandatory OSA evaluation for all patients (Era 2). RE...

PURPOSE The aim of this study was to determine the diagnostic value of three screening questionnaires in identifying Korean patients at high risk for obstructive sleep apnea (OSA) in a sleep clinic setting in Korea. MATERIALS AND METHODS Data were collected from 592 adult patients with suspected OSA who visited a sleep center. All patients completed the Sleep Apnea of Sleep Disorder Questionn...

Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) have synergistic detrimental effects. Their comorbid association leads to compromised gas exchange (hypoxia and hypercapnia) and higher rates of morbidity and death. As our understanding of the pathophysiologic processes of sleep evolves, the relationship between OSA and obstructive lung diseases such as COPD ("overl...

Obstructive sleep apnea (OSA) is defined as episodic apnea, or cessation of breathing, during sleep, in which the period of apnea should last for more than 10 seconds. It is usually due to partial or complete collapse of the upper airway and is associated with snoring, restlessness, daytime headache and somnolence. The diagnosis relies on history and requires polysomnography for confirmation. S...

PURPOSE To evaluate the frequency of obstructive sleep apnea (OSA) in obese patients scheduled for bariatric surgery and their identification for risk of OSA by Berlin Questionnaire (BQ) and excessive daytime sleepiness by Epworth Sleepiness Scale (ESS). METHODS Fifty nine patients were evaluated by BQ and ESS. Out of these individuals, 35 performed a full-night sleep study using a type 3 por...

Obstructive sleep apnea (OSA) is common in patients with renal disease, and an association between OSA and proteinuria has been proposed. However, the effect on proteinuria of OSA treatment with continuous positive airway pressure (CPAP) is unknown. We experienced a case of severe OSA, where proteinuria was clearly improved after CPAP initiation without any changes of medication or body weight....

Background: It has been implicated that obstructive sleep apnea (OSA) is associated with increased risk of cardiovascular disease including stroke, myocardial infarction, coronary artery disease (CAD) and hypertension. The aim of this study was to investigate the correlation between OSA and severity of atherosclerosis assessed by angiography. Methods: This study included 337 patients ...

A major concern with sleep-disordered breathing conditions, which include obstructive sleep apnea (OSA), central apnea, and congenital central hypoventilation syndrome (CCHS), is the high incidence of accompanying autonomic dysfunction and metabolic disorders. Patients with OSA show exaggerated sympathetic tone, leading to hypertension, cardiac arrhythmia, profuse sweating, impaired cerebral pe...
