BACKGROUND Overnight polysomnography is expensive and time consuming. An approach based on a logistic regression model and overnight pulse oximetry has been developed to determine which of the snorers referred to our sleep laboratory need polysomnography. METHODS The variables entered in the regression model were derived from questionnaires completed by 95 habitual snorers and 89 patients wit...
AIM Sleep disordered breathing is a common problem in childhood that encompasses a spectrum of disorders extending from primary snoring to obstructive sleep apnea. This study aims to investigate the results of children undergoing evaluation with polysomnography in the sleep laboratory of a tertiary care hospital. MATERIAL AND METHODS Demographic and clinical features as well as sleep associat...
STUDY OBJECTIVES The upper airway resistance syndrome (UARS) is a recently described form of sleep-disordered breathing in which transient increases in upper airway resistance result in repetitive EEG arousals. UARS is not associated with apnea or diminished airflow, although snoring and excessive daytime somnolence (EDS) are common. This report describes a subset of patients with UARS diagnose...
OBJECTIVES To further validate a questionnaire about symptoms of childhood obstructive sleep apnea (OSA) and to compare the questionnaire with polysomnography in their ability to predict outcomes of adenotonsillectomy. DESIGN Retrospective analysis of data from a longitudinal study. SETTING University-based sleep disorders laboratory. PARTICIPANTS The Washtenaw County Adenotonsillectomy C...
Dimensions of sleepiness and their correlations with sleep-disordered breathing in mild sleep apnea.
OBJECTIVE There are many ways of assessing sleepiness, which has many dimensions. In patients presenting a borderline apnea-hypopnea index (AHI, expressed as events/hour of sleep), the mechanisms of excessive daytime sleepiness (EDS) remain only partially understood. In the initial stages of sleep-disordered breathing, the AHI might be related to as-yet-unexplored EDS dimensions. METHODS We r...
Sleep deprivation is common in intensive care unit (ICU) patients. The criterion standard for sleep monitoring, polysomnography, is impractical in ICU. Actigraphy (a wrist watch indicating amount of sleep) proved to be a good alternative in non-ICU patients, but not in prolonged mechanically ventilated patients, probably due to ICU-acquired weakness. Short-stay ICU patients do not suffer from I...
The most reliable technique for the diagnosis of nocturnal frontal lobe epilepsy (NFLE) is nocturnal video-polysomnography, which is an expensive procedure and unavailable in many Departments of Neurology and Epileptology around the world. The aim of the present study was to evaluate the role of routine video-EEG and video-EEG after sleep deprivation, during the daytime, in the diagnosis of NFL...
These practice parameters are an update of the previously-published recommendations regarding the indications for polysomnography and related procedures in the diagnosis of sleep disorders. Diagnostic categories include the following: sleep related breathing disorders, other respiratory disorders, narcolepsy, parasomnias, sleep related seizure disorders, restless legs syndrome, periodic limb mo...
