BACKGROUND: It is widely known that patients with chronic rhinosinusitis (CRS) commonly experience sleep disruption. Many of these patients have the associated diagnosis of obstructive sleep apnea (OSA). However, little is known about the risk factors for developing OSA in the CRS population. OBJECTIVE: To identify the risk factors for OSA in CRS to determine who should be screened for OSA among patients with CRS. METHODS: We evaluated a large cohort of patients with confirmed diagnostic criteria for CRS...

INTRODUCTION: Children with Down syndrome (DS) have a high incidence of obstructive sleep apnea (OSA) that is often associated with hypoventilation. Little is known, however, about the prevalence of sleep-associated hypoventilation independent of OSA in these children. METHODS: Retrospective chart review of all children with DS under 18 years of age undergoing polysomnography at a tertiary care paediatric hospital during a 2-year period. Exclusion criteria were as follow: those requiring oxygen or positive-pressure ventilation; with tracheostomy, baseline hypoxia, unrepaired cyanotic heart disease, pulmonary hypertension, and cerebral palsy; or OSA with >5 obstructions/hour...

Obstructive sleep apnea (OSA) leads to multiple end-organ morbidities that are mediated by the cumulative burden of oxidative stress and inflammation. Both OSA and inflammation play key roles in increased risk of cardiovascular disease (CVD). Thus, we hypothesized that the combination of inflammation and OSA could accelerate the development of metabolic syndrome (MetS) in a large cohort study.A total of 1835 participants were randomly selected from the ongoing Korean Genome and Epidemiology Study for the years between 2007 and 2015...

As a surrogate measure of blood pressure, pulse transit time (PTT) is commonly used in studies investigating arterial function and respiratory sleep disturbance. A systematic search of the literature was conducted with the aim of reviewing the usefulness of the technique within pediatric sleep studies. All studies that used PTT as a diagnostic tool during sleep in infants, children or adolescents were considered. The search yielded 425 articles, of which 21 full-text articles met inclusion criteria, the majority reporting on obstructive sleep apnea (OSA)...

OBJECTIVE: Restless legs syndrome (RLS) is a common neurological movement disorder occurring in approximately 10% of the general population. The prevalence of moderately severe RLS is 2.7% overall (3.7% for women and 1.7% for men). Epilepsy is also a common neurological disorder with significant associated morbidity and impact on quality of life. We evaluated the severity and frequency of primary RLS in patients with localization-related temporal lobe epilepsy (TLE) and investigated the role of prodromal RLS symptoms as a warning sign and lateralizing indicator...

STUDY OBJECTIVES: Polysomnography is the gold standard for diagnosis and characterization of severity of sleep-disordered breathing. Accuracy and reliability of the technology used are critical to the integrity of the study's interpretation. Strict criteria for obstructive sleep apnea in children are lacking and diagnosis often requires consideration of frequency of respiratory events in addition to other measures. Current American Academy of Sleep Medicine recommendations for pediatric patients includes use of respiratory inductance plethysmography (RIP) belts, whereas polyvinylidene fluoride (PVDF) belts are currently only acceptable for use in adults...
