Revised 7 April 2011. Accepted 11 April 2011. Available online 5 July 2011.View full text Restless legs syndrome (RLS) is a distressing sleep and sensorimotor disorder that affects a large percentage of adults in the western industrialized world and is associated with profound reductions in quality of life. However, the etiology of RLS remains incompletely understood. Enhanced understanding regarding both the antecedents and sequelae of RLS could shed new light on the pathogenesis of RLS. Evidence from an emerging body of literature suggests associations between RLS and diabetes, hypertension, obesity, and related conditions linked to sympathetic activation and metabolic dysregulation, raising the possibility that these factors may likewise play a significant role in the development and progression of RLS, and could help explain the recently documented associations between RLS and subsequent cardiovascular disease. However, the relation between RLS and these chronic conditions has received relatively little attention to date, although potential implications for the pathogenesis and treatment of RLS could be considerable. In this paper, we systematically review the recently published literature regarding the association of RLS to cardiovascular disease and related risk factors characterized by sympathoadrenal and metabolic dysregulation, discuss potential underlying mechanisms, and outline some possible directions for future research.prs.rt("abs_end");Restless legs syndrome; RLS; Ekbom disease; Cardiovascular disease; Hypertension; Diabetes; Impaired glucose tolerance; Obesity; Weight gain; Dyslipidemia; Autonomic dysfunction; HPA axis dysfunction

The Ritchie Centre, Monash Institute of Medical Research, Monash University, Melbourne, AustraliaReceived 9 December 2011. Revised 20 April 2012. Accepted 20 April 2012. Available online 29 May 2012.View full text Sleep disordered breathing (SDB) is a common disorder in both adults and children and is caused by the obstruction of the upper airway during sleep. Unlike adults, most cases of paediatric SDB are due to the presence of enlarged tonsils and adenoids, thus the main treatment option is adenotonsillectomy (T&A). It is well known that obstructive sleep apnoea in adults increases the risk for hypertension, coronary artery disease and stroke, and there is now mounting evidence that SDB also has a significant impact on the cardiovascular system in children with reports of elevated blood pressure, endothelial dysfunction and altered autonomic cardiovascular control. As there is now substantial evidence that elevated blood pressure in childhood is carried on to adulthood it is important to know if treatment of SDB improves cardiovascular outcomes. Studies in adults have shown that treatment of SDB leads to improvements in cardiovascular function, including a reduction in pulmonary artery pressure, systemic blood pressure and endothelial dysfunction. However, studies exploring the outcomes of treatment of SDB in children on the cardiovascular system are limited and varied in their methodology and outcome measures. As a number of cardiovascular disturbances are sequelae of SDB, early detection and management could result in the reduction of elevated blood pressure in children, and consequently a reduction in cardiovascular morbidity in adulthood. The aim of this review is to summarise the findings of studies to date which have investigated the cardiovascular outcomes in children treated for SDB and to make recommendations for future management of this very common disease.prs.rt("abs_end");Adenotonsillectomy; Blood pressure; Cardiovascular; Children; Hypoxaemia; Inflammation; Obstructive sleep apnoea; Sleep disordered breathing; Treatment
