BACKGROUND AND PURPOSE Epidemiological studies have suggested a pathophysiological link between sleep apnea syndrome and cerebrovascular diseases. The mechanism by which sleep disturbance can affect the predisposition to developing stroke is not clear. The aim of this study was to investigate whether patients with obstructive sleep apnea syndrome have an increase in atherosclerosis indicators a...

Background: Sleep apnea is temporary cessation or absence of breathing during sleep. Significant increase in blood pressure is clinically seen in apneic episodes. The aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (NAION) in a case control study. Methods: Nineteen NAION patients (9 men and 10 women) and 31 age and ...

Sleep Apnea Syndrome (SAS) is a multimorbid chronic disease with individual and societal deleterious consequences. Polysomnography (PSG) the multi-parametric reference diagnostic tool that allows manual quantification of apnea-hypopnea index (AHI) to assess SAS severity. The burden affecting nearly one billion people worldwide explaining remains largely under-diagnosed undertreated. development...

This paper presents methods to compensate and monitor the disturbance generated by electric traction units, considering their position in different times, in a railway system. For this purpose, first of all, experimental data of Italy traction system is used and its components are modeled. Then, using proposed algorithm a suitable location for a passive filter is determined. Subsequently, consi...

We develop a new visual test, designed as software for quantifying discrimination capacity under low-illumination conditions. This is an important task in the presence of visual disturbances, such as those perceived by subjects with some ocular pathologies. For this purpose, we propose a visual-disturbance index, checking the test with two groups of observers having different ocular pathologies...

OBJECTIVE To examine the efficacy of hyoid myotomy and suspension as a treatment of hypopharyngeal obstruction in obstructive sleep apnea. DESIGN Prospective, observational study. SETTING Academic medical center. PATIENTS Twenty-nine consecutive male patients with suspected hypopharyngeal obstruction INTERVENTIONS Patients underwent hyoid suspension. Uvulopalatopharyngoplasty with or wi...

OBJECTIVE To determine the effect of adjunctive quetiapine therapy on the sleep architecture of patients with bipolar or unipolar depression. METHODS This is a prospective, single-blind, repeated measures polysomnographic study. Sleep architecture was analyzed by overnight polysomnography, and subjective sleep quality was measured using the Pittsburgh Sleep Quality Index. The Hamilton Rating ...

OBJECTIVE Obstructive sleep apnea is common among patients with hypertrophic cardiomyopathy and may contribute to poor cardiovascular outcomes. However, obstructive sleep apnea is largely unrecognized in this population. We sought to identify the clinical predictors of obstructive sleep apnea among patients with hypertrophic cardiomyopathy. METHODS Consecutive patients with hypertrophic cardi...

OBJECTIVE To examine links between obstructive sleep apnea (OSA), insulin resistance, and dyslipidemia. STUDY DESIGN Obese (body mass index [BMI] >95th percentile for age and gender) children who snored (n = 62, 46 males, age 10.89 [5-16 years] underwent polysomnography and metabolic studies. RESULTS Respiratory disturbance index (RDI) was 9.23 (0-95), with 23 children (39%) recommended for...

BACKGROUND There are few reports about sleep disturbances in patients with chronic obstructive pulmonary disease (COPD) in Asian countries. OBJECTIVES To investigate the associations between sleep-disordered breathing (SDB) with hypoxemia and sleep quality, including sleep duration, in patients with COPD, we measured SDB and sleep quality including the objective sleep duration determined by a...
