BACKGROUND Obstructive sleep apnea syndrome (OSAS) has been indicated to contribute to the development of cardiovascular disease; however, the underlying mechanism remains unclear. This study aimed to test the hypothesis that OSAS may be associated with cardiovascular disease by elevating serum levels of inflammatory markers and causing arterial stiffening and endothelial dysfunction. METHODS...

OBJECTIVES We evaluated the outcome of adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) in children using polysomnography (PSG) data and a quality-of-life (QOL) instrument. METHODS We enrolled children (4 to 14 years of age) who had OSAS diagnosed by overnight PSG and who underwent both adenoidectomy and tonsillectomy between January 2003 and February 2008. All of them had compl...

Obstructive sleep apnea syndrome (OSAS) is a common and serious cause of metabolic, cardiovascular, and neurocognitive morbidity in children. Children with OSAS have increased upper airway resistance during sleep due to a combination of soft tissue hypertrophy, craniofacial dysmorphology, neuromuscular weakness, or obesity. Consequently, children with OSAS encounter a combination of oxidative s...

A 69-year-old non-obese Japanese man with obstructive sleep apnea syndrome (OSAS) complaining solely about night sweat was treated successfully with continuous positive airway pressure. Nocturnal sweating of a common symptom of OSAS is also caused by drugs/alcohol/heroin, malignancies, infections, gastro-esophageal reflux, and endocrine/rheumatologic diseases. Family physicians should include O...

A critical link between amyloid-beta (Aβ) and hypoxia has been demonstrated in in vitro and animal studies but has not yet been proven in humans. Obstructive sleep apnea syndrome (OSAS) is a common disorder that is characterized by nocturnal intermittent hypoxaemia. This study sought to examine the association between the chronic intermittent hypoxia and Aβ in OSAS patients. Forty-five cognitiv...

PURPOSE Current evidence supports a robust association between obstructive sleep apnea syndrome (OSAS) and the risk of coronary artery disease (CAD). YKL-40, a 40 kDa heparin- and chitin-binding glycoprotein, is found to be associated with the presence of CAD. This study aims to examine the association of serum levels of YKL-40 with the presence and severity of CAD in patients with OSAS. METH...

OBJECTIVES To evaluate the correlation between concentrations of the proinflammatory cytokines monocyte chemotactic protein 1 (MCP-1), adiponectin, interleukin 6 (IL-6), interleukin 8 (IL-8), and tumor necrosis factor (TNF) and patients with obstructive sleep apnea syndrome (OSAS). Repeated apnea attacks in patients with OSAS constitute a hypoxic condition, which induces tissue inflammation by ...

The prevalence of pediatric obstructive sleep apnea syndrome (OSAS) is approximately 3% in children. Adenotonsillar hypertrophy is the most common cause of OSAS in children, and obesity, hypotonic neuromuscular diseases, and craniofacial anomalies are other major risk factors. Snoring is the most common presenting complaint in children with OSAS, but the clinical presentation varies according t...

OBJECTIVE To evaluate the effect of obesity on obstructive sleep apnea syndrome (OSAS) by age in relation to anthropometric measurements. METHODS The medical records of 1,110 participants diagnosed with OSAS were analyzed according to age. All participants underwent nocturnal polysomnography and had their body mass index, waist circumference, neck circumference (NC), and waist-to-hip ratio me...

OBJECTIVES Obstructive sleep apnea syndrome (OSAS) is associated with major morbidity and mortality but OSAS is frequently under recognized. To promote awareness of OSAS, the Swiss Lung League launched an online questionnaire combined with annual advertisements in mass media. Characteristics of participants, prevalence of sleep apnea, OSAS-related symptoms, and their association with accidents ...
