To investigate the frequency of factors associated with restless legs syndrome (RLS) in patients with chronic obstructive pulmonary disease (COPD). ⋯ RLS is common in COPD. Patients with RLS have low creatinine, poorer quality of sleep, and more fatigue and depressive symptoms. RLS symptom severity is correlated to lower ferritin and severity of dyspnea.

Childhood sleep disordered breathing (SDB) peaks in the preschool years. We aimed to compare the effects of SDB on polysomnographic characteristics between preschool and school aged children. ⋯ We have demonstrated clinically important, age-related differences in sleep architecture in children with SDB. Preschool children with SDB maintain sleep efficiency and awaken fewer times throughout the night than do school aged children with a comparable severity of SDB, but experience more central apneas. This may have implications for the outcomes and treatment of SDB in children of different ages.

The objective of our study was to examine the prevalence rates of different sleep complaints among adolescent outpatients with major depressive disorder (MDD). Further, we examined whether depressed adolescents with and without different sleep disturbances differ in terms of severity of depression, the presence of comorbid psychiatric disorders, and the symptom profile of depression. ⋯ These findings suggest a close link between sleep disturbances and the severity of depression in adolescent outpatients with MDD. In particular, the link between sleep disturbances and thoughts about death and suicidal thoughts calls for attention to sleep problems among depressed adolescents in clinical settings.
