BACKGROUND Practice parameters for the treatment of obstructive sleep apnea syndrome (OSAS) in adults by surgical modification of the upper airway were first published in 1996 by the American Academy of Sleep Medicine (formerly ASDA). The following practice parameters update the previous practice parameters. These recommendations were reviewed and approved(More)
Pulse oximetry is a well-established tool routinely used in many settings of modern medicine to determine a patient's arterial oxygen saturation and heart rate. The decreasing size of pulse oximeters over recent years has broadened their spectrum of use. For diagnosis and treatment of sleep-disordered breathing, overnight pulse oximetry helps determine the(More)
SUMMARY OF RECOMMENDATIONS Modifying the sleep environment is recommended for the treatment of patients with RBD who have sleep-related injury. Level A Clonazepam is suggested for the treatment of RBD but should be used with caution in patients with dementia, gait disorders, or concomitant OSA.

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(More)
An 18-year-old woman with thrombotic thrombocytopenic purpura (TTP) had recurrent thrombocytopenia due to antiplatelet antibodies associated with systemic lupus erythematosus (SLE). The simultaneous occurrence of TTP and SLE is rare. We briefly summarize eight previously reported cases in which these two diseases have developed in the same patient within a(More)
