Comparative Study
Diagnostic performance of single airflow channel recording (ApneaLink) in home diagnosis of sleep apnea.
ApneaLink is a novel single-channel screening device for sleep apnea detection which is based on pressure-transduced measurement of oronasal airflow, summarised as respiratory disturbance index per hour of recording time (RDI(ApneaLink)). We tested ApneaLink's diagnostic performance in a patient population with high prevalence of sleep apnea. ⋯ ApneaLink is an accurate screening tool for sleep apnea in a population with high prevalence of the disorder.

Comparative Study
Continuous positive airway pressure device-based automated detection of obstructive sleep apnea compared to standard laboratory polysomnography.
Obstructive sleep apnea (OSA) is a common health problem that affects more than 2-4% of the US population. Polysomnography (PSG) is the gold standard for diagnosing OSA. PSG is, however, expensive, time-consuming, and not always readily accessible. Hence, alternative diagnostic methods such as home-based testing have been evaluated. We studied the ability of the REMstar Pro (RSP2, a brand of continuous positive airway pressure (CPAP) device) to identify abnormal breathing events in subjects with OSA and compared this with breathing events simultaneously determined by laboratory-based PSG. ⋯ The monitoring of residual sleep-disordered breathing on treatment, in addition to adherence, is an important objective therapeutic target in OSA. The REMstar Pro detects sleep-disordered breathing events similar to that of a manually scored PSG-for apnea but not for hypopnea-and merits further investigation as a device to determine disease severity and treatment efficacy.

Case Reports
Improvement in quality of life after adenotonsillectomy in a child with Prader Willi syndrome.
We report a child with Prader Willi syndrome who developed obstructive sleep apnea (OSA). This patient underwent surgical treatment for OSA. There was improvement not only on her OSA but in her quality of life score as well. This report highlights the need for a comprehensive assessment in the management of patients with Prader Willi syndrome.
