Central alveolar hypoventilation is rarely encountered. This case report describes a young woman who was recently diagnosed with hypertension and ischemic heart disease. She presented to the emergency room with hypercapnic respiratory failure, for which she was mechanically ventilated. This was preceded by an acute upper respiratory tract infection. She was initially suspected to have Guillain-Barré syndrome, but further investigations ruled out neuromuscular or autoimmune disorders. Sleep-related hypoventilation was suspected after she experienced recurrent apneas at night that resulted in re-intubation...

BACKGROUND: Periodic leg movements during sleep (PLMS) have been associated with an increased risk for cardiovascular diseases and there is a high prevalence of PLMS found in patients with obstructive sleep apnea syndrome (OSAS). We evaluated patients with transient ischemic attack (TIA) for PLMS and respiratory related leg movements (RRLM), versus a control group without TIA. METHODS: Twenty-five patients with TIA and 34 patients with no vascular diagnosis were referred for polysomnography...

The aim of the present study was to summarize the risk factors for bruxism that were identified by a systematic search of the literature published between 2007 and 2016. Depending on the size of the odds ratios (ORs) and the lower limit of the 95% confidence intervals indicated by the reports, four risk categories were differentiated. Among others, emotional stress, consumption of tobacco, alcohol, or coffee, sleep apnea syndrome, and anxiety disorders were recognized as important factors among adults. In children and adolescents, apart from distress, behavioral abnormalities and sleep disturbances predominated...

Continuous positive airway pressure (CPAP) is being increasingly used in children of all age ranges. The limited number of commercially available masks especially in infants and young children may complicate its use and compliance. In this report, we describe our experience with the use of the Optiflow™ (Fisher and Paykel Healthcare) Nasal Cannula attached to a regular CPAP device in the setting of chronic CPAP use. This interface consists of a nasal cannula and was originally designed for the delivery of high-flow oxygen therapy...

Continuous positive airway pressure (CPAP) is the first-choice treatment for obstructive sleep-disordered breathing. Automatic bilevel ventilation can be used to treat obstructive sleep-disordered breathing when CPAP is ineffective, but clinical experience is still limited. To assess the outcome of titration with CPAP and automatic bilevel ventilation, the charts of 356 outpatients (obstructive sleep apnea, n = 242; chronic obstructive pulmonary disease + obstructive sleep apnea overlap, n = 80; obesity hypoventilation syndrome [OHS], n = 34; 103 females) treated for obstructive sleep-disordered breathing from January 2014 to April 2017 were reviewed...

Sleep apnea hypopnea syndrome (SAHS) is an independent risk factor for cardiovascular diseases. However, the pathophysiology between them is not yet clear. This paper seeks to understand how respiratory events impact the cardiovascular system by heart rate variability. We compared the differences between successional pathological respiratory events (PR) and pure normal respiration (NR) during sleep. The transitions between normal and pathological respiration (TR) were also analyzed. Thirteen patients who suffered moderate or severe SAHS were enrolled in this study...

BACKGROUND: Sleep-disordered breathing (SDB) is common in pregnancy, but there are limited data on predictors. OBJECTIVES: The objective of this study was to develop predictive models of sleep-disordered breathing during pregnancy. STUDY DESIGN: Nulliparous women completed validated questionnaires to assess for symptoms related to snoring, fatigue, excessive daytime sleepiness, insomnia, and restless leg syndrome. The questionnaires included questions regarding the timing of sleep and sleep duration, work schedules (eg, shift work, night work), sleep positions, and previously diagnosed sleep disorders...

OBJECTIVE: Obstructive sleep apnea hypopnea syndrome (OSAHS) is an independent risk factor for many clinical complications. However, how OSAHS cause multiple organ injury and initiate inter-organ communication remains unclear. Moreover, despite it is well-recognized that chronic intermittent hypoxia (CIH) is a main feature of OSAHS, specific contribution of CIH to overall OSAHS-initiated pathological complications remains unclear. This study aimed to use an unbiased proteomic approach to determine whether OSAHS alters protein profiles of serum extracellular microvesicles (SEMVs) and how CIH contributes to such alterations...

There is a wide range of potentially modifiable risk factors for Alzheimer's disease and dementia, including cardiovascular risk factors (e.g. hypertension, diabetes, dyslipidemia, obesity, sleep-apnea syndrome), psychosocial factors (e.g., depression), health behaviors (e.g., low level of physical or mental activity, smoking status), and head trauma. In the elderly, weight loss associated with frailty and sarcopenia is another risk factor for dementia. Recent epidemiological studies have shown that the prevalence of dementia has declined in the US and European countries during the last 20 years...

Cornelia de Lange syndrome (CdLS) is a rare genetic disorder that is characterized by specific facial, skeletal, and behavioral features associated with variable degrees of intellectual disabilities. Sleep disturbances have been reported in patients with CdLS including insomnia, sleep-disordered breathing, intrinsic sleep disorders, and circadian rhythm disorders. The prevalence of sleep-related breathing disorders, in particular, obstructive sleep apnea (OSA), was conducted using validated questionnaires. We report the first case of CdLS that confirmed a moderate to severe degree of OSA using overnight polysomnography, which is the gold standard diagnostic test for OSA...
