OBJECTIVE The prevalence of obstructive sleep apnea-hypopnea syndrome (OSAHS) in the general pediatric population ranges from 1% to 3%. However, its prevalence in an unselected population of obese children is unknown. We studied the association between obesity and OSAHS in children diagnosed with the syndrome in a cohort of boys and girls (age range, 2-14 years) referred to the pediatric respir...

BACKGROUND It is well known that the sleeping position influences the rate of apnea-hypopnea events; however, whether events in one position may have more influence on daytime sleepiness than events in another position has not been thoroughly investigated. OBJECTIVES We retrospectively examined the relationship between the body position-specific apnea-hypopnea index (AHI) and daily sleepiness...

Current treatment options are successful in 40% to 60% of children with persistent obstructive sleep apnea after adenotonsillectomy. Residual obstruction assessments are largely subjective and do not clearly define multilevel obstruction. We endeavor to use computational fluid dynamics to perform virtual surgery and assess airflow changes in patients with Down syndrome and persistent obstructiv...

Sleep apnea-hypopnea syndrome (SAHS) is characterized by recurrent episodes of upper airway collapse, which may be complete (apnea) or partial (hypopnea). The direct consequences of upper airway collapse are falls in oxygen saturation levels and arousals, which are, in turn, responsible for excessive daytime sleepiness and neurological and psychiatric disorders.1,2 The prevalence of SAHS has be...

Nocturnal cardiac arrhythmia is a common clinical feature of obstructive sleep apnea syndrome. Pathologically relevant rhythm disturbances such as atrioventricular block or ventricular tachycardia are known to occur mainly in patients with a high apnea-hypopnea index and marked oxygen desaturation. We report on a patient with mild obstructive sleep apnea syndrome who nevertheless showed intermi...

Study Objectives. We identified the associated conditions of patients less than 12 months of age who were referred for polysomnogram (PSG) studies. We collated PSG findings and physician interpretation. We determined the correlation between the recommended treatment by the PSG interpreting physician and actual prescribed treatment by the referring or subjects' physician. We determined adherence...

OBJECTIVE The purpose of the present prospective study of older adults was to (1) explore the nature and frequency of sleep disorder in a sample of self-identified, sleepy/tired individuals and (2) compare symptom presentation of women and men who were subsequently diagnosed with sleep apnea/hypopnea. METHOD Participants were 112 community-based older adults self-identified with daytime sleep...

Background: Obstructive sleep apnea (OSA) is a global disease with rising incidence along its co-morbidities, especially the metabolic syndrome. One of main components contributing to obesity. Objective: To evaluate association obesity obstructive (OSA). Method: This cross-sectional analytical study was conducted in Department Otolaryngology, Sir Salimullah Medical College Hospital, Dhaka, and ...

BACKGROUND Obstructive sleep apnea syndrome (OSAS) is characterized by repetitive collapse of the upper airway during sleep. Red blood cell distribution width (RDW) increases platelet activation and has been reported as an independent predictor of adverse outcomes in the general population and is believed to be associated with cardiovascular morbidity and mortality. We evaluated RDW, mean plate...

OBJECTIVES The purpose of this study was to investigate the effect of a mandibular advancement device on different grades of obstructive sleep apnea using a relatively simple test for the apnea-hypopnea index to determine if a mandibular device will be effective. MATERIAL AND METHODS A total of 68 patients with obstructive sleep apnea syndrome (OSAS) including, 31 with mild, 23 with moderate ...
