Surgical treatment for retro-lingual obstruction in patients suffering from obstructive sleep apnea syndrome remains a problem for which there is no simple solution. The techniques most in use (tongue suspension, genioglossal advancement with hyoid suspension) are effective primarily as stabilization methods modifying neither tongue position, nor volume and only produce appreciable results when...

STUDY OBJECTIVES Nocturnal and early morning elevation of blood pressure are common acute manifestations of obstructive sleep apnea (OSA) that do not always carry over into a sustained daytime hypertension. Using pulse wave analysis, we examined the effect of OSA on arterial stiffness and central aortic blood pressure to assess whether each would be elevated independent of diurnal changes in pe...

A digital recording device developed to monitor heart rate (HR) and breathing sounds (snoring), and used to screen subjects for obstructive sleep apnoea syndrome (OSAS), was investigated. This device is called the MESAM and is currently commercially available in some western European countries. The computer-based automatic scoring systems provided with the equipment and a hand-scoring technique...

BACKGROUND AND PURPOSE Patients with TIA and minor stroke are at high risk for recurrent stroke. Obstructive sleep apnea (OSA) may increase this risk. The objectives of our study were to determine the prevalence and severity of OSA and its clinical presentation in this population. METHODS Patients who presented with TIA and minor stroke completed a questionnaire and nocturnal cardiopulmonary ...

BACKGROUND The Tucson Children's Assessment of Sleep Apnea study (TuCASA) was designed to investigate the prevalence and correlates of objectively measured sleep-related breathing disorder (SBD) in preadolescent Hispanic and white children. OBJECTIVE To describe the associations of SBD and elevation in resting blood pressure in the first 239 children enrolled in TuCASA. DESIGN Children betw...

CONTEXT Adenotonsillar tissue hypertrophy and obstructive sleep apnea have been reported during short-term GH treatment in children with Prader-Willi syndrome (PWS). OBJECTIVE We conducted an observational study to evaluate the effects of long-term GH therapy on sleep-disordered breathing and adenotonsillar hypertrophy in children with PWS. DESIGN This was a longitudinal observational study...

OBJECTIVES To evaluate the reliability of home respiratory polygraphy for the diagnosis of sleep apnea-hypopnea syndrome (SAHS) and to compare the cost of this technique with that of nighttime polysomnography performed in a sleep laboratory. PATIENTS AND METHODS This was a prospective study of a random sample of patients with clinically suspected SAHS in which the participants who underwent b...

STUDY OBJECTIVES To determine the frequency, symptoms, and polygraphic features of sleep-related breathing disorders (SRBD) in adolescents aged 12 to 16 years. DESIGN Cross-sectional study. SETTING Randomly selected secondary schools in the city of Seville, SPAIN: PARTICIPANTS A general population sample of adolescents (n = 101; mean [+/- SD] age, 13.2 +/- 0.8 years). INTERVENTIONS An 8...

In patients with the sleep apnoea/hypopnoea syndrome (SAHS), accurate and timely diagnostic evaluation and initiation of effective treatment is important. Therefore, an increasing number of limited sleep studies are now performed nowadays diagnosing the SAHS in typical patients. It was the aim of the present study to evaluate the diagnostic accuracy of one such system, the updated ResMed Sulliv...
