Comparative Study
Comparison of two servo ventilator devices in the treatment of complex sleep apnea.
Servo ventilation (SV) devices generate positive airway pressure with a variable pressure support that changes in response to a patient's own respiratory output. Two currently available SV devices-VPAP-AdaptSV® and BIPAP-AutoSV®-have been used in treatment of complex sleep apnea (CompSAS), but no side-by-side comparisons are available. ⋯ Our retrospective data indicate that the two servo-ventilation devices are comparable means of controlling complex sleep apnea, and the compliance with them is high.

Assess the rate of augmentation as it occurs during standard long-term dopaminergic treatment of RLS, potential risk factors or predictors of augmentation, the relationship between treatment duration and augmentation, and the clinical impact of augmentation on subjects' health outcomes. ⋯ As currently used, long term dopaminergic treatment for an average ± SD of 2.7 ± 2.4 years produced significant augmentation problems in at least 20% of the patients and only 25% of the patients were totally free of this problem. It is important for physicians to carefully screen patients for changes in RLS symptoms for as long as they are on dopamine agents, with particular attention paid to those patients who present with the most severe RLS symptoms prior to treatment initiation. Given the marked increase in suffering with augmentation, a method for early detection and intervention would be an important contribution to the effective management and treatment of RLS.

Comparative Study
Assessing insomnia in adolescents: comparison of Insomnia Severity Index, Athens Insomnia Scale and Sleep Quality Index.
To compare the psychometric properties of the Chinese versions of Insomnia Severity Index (ISI), Athens Insomnia Scale (AIS) and Sleep Quality Index (SQI) for assessment and screening of insomnia in adolescents. ⋯ The Chinese versions of ISI, AIS and SQI are reliable and valid instruments. The ISI and AIS appear to have better psychometric properties than the SQI.

Hypercapnic ventilatory failure due to restrictive disorders may have a negative impact on sleep architecture. Non-invasive ventilation (NIV) may improve arterial blood gases but may adversely affect sleep. We assessed sleep structure and blood gases before and during NIV in patients with restrictive disorders in hypercapnic ventilatory failure. ⋯ Hypercapnic ventilatory failure in restrictive disorders profoundly affects sleep quality. NIV can improve not only blood gases, but also sleep architecture.

To investigate the effects of sleep deprivation on physical health, cognition, and work performance in residents and interns who suffer from chronic sleep deprivation. ⋯ These results suggested that sleep deprivation in residents and interns might affect their health as well as work performance that might influence the quality of patient care, although active compensatory brain mechanisms could be involved to preserve their performance.
