background and objective: the main causes of nocturnal hypoxemia are pulmonary diseases or sleep related breathing disorders. in overlap syndrome, the co-existence of chronic obstructive pulmonary disease (copd) and ob-structive sleep apnea (osa), blood oxygen alteration, and hypercapnia may be more severe. we aimed to study hypox-emia markers in osa patients with or without copd. materials and...

Sleep apnea and related disorders are not uncommon in abstinent alcoholics. We assessed the relationship between age and the presence and severity of sleep-disordered breathing in alcoholism by performing one night of polysomnography on 75 abstinent alcoholic subjects undergoing treatment for alcoholism. Sleep-disordered breathing (defined as 10 or more apneas plus hypopneas/hr of sleep) was pr...

OBJECTIVE The purpose of this work was to determine whether, in children with metabolic syndrome and sleep-disordered breathing, metabolic markers separate them from children with metabolic syndrome without sleep-disordered breathing and whether treatment of sleep-disordered breathing with continuous positive airway pressure is associated with an improvement in metabolic derangement. PATIENTS...

Sleep disordered breathing with or without nocturnal hypercapnic hypoventilation is a common complication of respiratory muscle weakness in childhood neuromuscular disorders. Nocturnal hypercapnic hypoventilation as a sign of respiratory muscle fatigue, portends a particularly poor prognosis. We aimed at identifying daytime predictors of sleep disordered breathing at its onset and sleep disorde...

Sleep apnea and related disorders contribute to disturbed sleep in abstinent alcoholics. In an earlier report from our group, sleep-disordered breathing was common and increased with age in a cohort of 75 abstinent alcoholics. We now report an extension of the previous work that includes studies of an additional 103 abstinent alcoholics undergoing treatment for alcoholism (total sample = 188) a...

BACKGROUND Allergy represents a risk factor at the base of sleep-disordered breathing in pediatric age. Among allergic diseases, the atopy is characterized by a tendency to be "hyperallergic." Sleep-disordered breathing is also known in orthodontics as correlated with the morphology of craniofacial complex. The aim of this study was to investigate the relation between atopy and sleep-disordered...

BACKGROUND Sleep-disordered breathing is a common condition associated with adverse health outcomes including hypertension and cardiovascular disease. The overall objective of this study was to determine whether sleep-disordered breathing and its sequelae of intermittent hypoxemia and recurrent arousals are associated with mortality in a community sample of adults aged 40 years or older. METH...

The aim of the present study was to compare the prevalence of sleep-disordered breathing among Hispanic and white Americans and Japanese. A 1-night sleep study using a single-channel airflow monitor was performed on 211 Hispanics and 246 Whites from the Minnesota field centre (St Paul, MN, USA) of the Multi-Ethnic Study of Atherosclerosis (MESA), and 978 Japanese from three community-based coho...

R ecently, sleep-disordered breathing and nocturnal hypoxia have been recognized to increase the risk of cerebrovascular disease. Kirkham et al reported that nocturnal hypoxemia was a predictor of future cerebrovascular events in sickle-cell disease. However, it remains unclear whether nocturnal hypoxemic episodes directly lead to nocturnal onset stroke, because other predisposing conditions mi...
