Introduction: Impaired sleep has been reported as an important nonmotor feature in dystonia, but so far, self-reported complaints have never been compared with nocturnal video-polysomnographic (PSG) recording, which is the gold standard to assess sleep-related disorders. Methods: Twenty patients with idiopathic isolated cervical dystonia and 22 healthy controls (HC) underwent extensive clinical investigations, neurological examination, and questionnaire screening for excessive daytime sleepiness and sleep-related disorders...

INTRODUCTION: Obesity is a disease that is closely associated with deleterious respiratory effects such as the Obesity Hypoventilation Syndrome which conventionally includes awake hypercapnia. There are studies addressing the detection of daytime hypercapnia with the patient either in sitting or standing position. However, there are no studies in obese subjects with a normal daytime PaCO2 in whom the detection of hypercapnia is made in the supine position. It is feasible that the physiopathological changes that occur in obese patients when they adopt the supine position lead to increased PaCO2 levels or hypercapnia...

BACKGROUND: Obstructive sleep apnoea (OSA) is characterised by repeated episodes of pauses in breathing during sleep due to obstruction of the upper airway that result in transient hypoxaemia, sleep fragmentation and long-term cardiovascular disease. The most common risk factors for OSA include: obesity, age over 50 and neck circumference of more than 41 cm for females and more than 43 cm in males. Sleep apnoea is more common in men than in women. The aim of the conducted research was to evaluate relations between the anthropometric features connected with adipose tissue distribution and the severity of OSA...

Snoring is caused by the vibration of structures of the oral cavity, such as the soft palate, uvula, tonsils, base of the tongue, epiglottis, and lateral pharyngeal walls. When these structures collapse and obstruct the airway, apnea occurs. Obstructive sleep apnea syndrome (OSAS) is characterized by repeated periods of upper airway obstruction, a decrease in arterial oxygen saturation, and interrupted sleep. The prevalence of OSAS is 1% to 5% in men and 1.2% to 2.5% in women. Crucial factors in deciding the surgical approach include a detailed ear-nose-throat examination, Muller maneuver, sleep endoscopy, and apnea hypopnea index scores...

OBJECTIVE: Obstructive sleep apnea syndrome is associated with cardiovascular diseases and thromboembolic events. The mean platelet volume (MPV) is a predictor of cardiovascular thromboembolic events. The aim of the present study is to investigate the association between the MPV and disease severity in patients with obstructive sleep apnea syndrome. METHODS: We prospectively included 194 obstructive sleep apnea syndrome patients without cardiovascular disease (mean age 56...

OBJECTIVES: Serum adiponectin levels have been found to be lower in patients with obesity, hypertension, and coronary artery diseases. In this study, we aimed to evaluate serum adiponectin levels in patients with obstructive sleep apnea syndrome (OSAS) and to correlate these levels with the severity of OSAS. STUDY DESIGN: In 62 OSAS patients (39 males, 23 females) and 32 controls (23 males, 9 females) determined by polisomnography, serum adiponectin levels were analyzed by the ELISA method...

BACKGROUND: Sleep-related breathing disorders are common in patients with chronic heart failure (CHF) and contribute to exacerbation of CHF. The effects of biventricular stimulation (CRT) seem to exceed the improvement of mechanical heart performance and are likely to affect other aspects of CHF pathophysiology. The aim of the study was to assess the influence of CRT on subjective and objective sleep features. MATERIAL AND METHODS: Twenty seven consecutive patients (aged 67...

This study presents different methods for automatic sleep classification based on heart rate variability (HRV), respiration and movement signals recorded through bed sensors. Two methods for feature extraction have been implemented: time variant-autoregressive model (TVAM) and wavelet discrete transform (WDT); the obtained features are fed into two classifiers: Quadratic (QD) and Linear (LD) discriminant for staging sleep in REM, nonREM and WAKE periods. The performances of all the possible combinations of feature extractors and classifiers are compared in terms of accuracy and kappa index, using clinical polysomographyc evaluation as golden standard...

BACKGROUND AND OBJECTIVE: The objective was to evaluate abnormalities in the quality of dreams after the use of efavirenz. PATIENTS AND METHOD: Ten HIV patients without neuropsychiatric diseases underwent a polisomnography (PSG) study before and after efavirenz treatment, [after 10.4 (SD 5.4) days]. Patients were awoke after REM phases to record their dreams. All patients had therapeutic efavirenz plasma levels. RESULTS: Dreams were recalled in 84% before efavirenz and 43% after efavirenz (p=0...

AIM: to obtain the OSAS prevalence and risk factors of OSAS in obese early adolescents and to create a scoring system based on risk factors for diagnosing OSAS. METHODS: an observational study in Jakarta, November 2007 until December 2008 on obese adolescents aged 10-12 years with snoring. Subjects underwent clinical examination, lung function test, paranasal sinus X-ray, and polisomnography. Measured outcomes were diagnosis of OSAS; sensitivity, specificity, predictive values, and likelihood ratios of a scoring system based on risk factors...

Analysis and classification of sleep stages is essential in sleep research. In this particular study, an alternative system which estimates sleep stages of human being through a multi-layer neural network (NN) that simultaneously employs EEG, EMG and EOG. The data were recorded through polisomnography device for 7 h for each subject. These collective variant data were first grouped by an expert physician and the software of polisomnography, and then used for training and testing the proposed Artificial Neural Network (ANN)...

BACKGROUND: Heart rate turbulence (HRT) assessment is used as noninvasive method based on physiological sinus node response to the premature ventricular beat. Blunted HRT may indicate the autonomic nervous system impairment and can be helpful in identifying high-risk patients. Obstructive sleep apnea syndrome (OSAS) leads to cardiovascular complications. Autonomic nervous system and baroreflex dysfunctions may play the main role in the development of cardiovascular diseases. In the present study we aimed to assess HRT parameters in OSAS patients with and without coronary artery disease (CAD) in comparison to control group...

Obstructive Sleep Apnea Syndrome (OSAS) is a very common disease in work age. Aim of study is to assess the impact of OSAS in a workers population. 138 workers (M 117, F 21), age 35-65 (mean 52.66 +/- 3.042) consecutively referred to Respiratory Hospital Monaldi and to Occupational Health Medicine Department of Second University of Naples performed an anthropometric evaluation of BMI, neck and an overnight polisomnography with Embletta X10 (Flaga Medical Devices; Reykjavik, Iceland). Workers' population was divided into three groups according to the impact of daytime sleepiness on work efficiency...

A total of 135 consecutive, unrelated, multiple sclerosis (MS) patients were interviewed for symptoms suggestive of restless legs syndrome (RLS) and REM sleep behavior disorder (RBD), using semi-structured questionnaires. Some 118 unrelated healthy controls of similar sex and age distribution were included for comparison. Patients and controls with equivocal symptoms were re-evaluated by a sleep disorders specialist and video-polisomnography in those who fulfilled the criteria for RBD. We did not find significant differences in frequency (13...

UNLABELLED: Obstructive sleep apnea can be associated with daytime chronic hypercapnia in some patients, but the prevalence of the phenomenon is highly variable in the published literature. The most often it is found in patients with coexisting COPD. There is also an evidence of persisting hypercapnia in OSA patients without other respiratory disease. In previous studies lung function impairment, obesity, gender, severity of OSAS have been considered to contribute to daytime hypercapnia...

UNLABELLED: The prevalence of OSA rises with age, however it is also diagnosed in patients below the age of 35 years. Aim of the paper was the camparison of the severity and clinical features of OSA in young and elderly subjects. The study was a retrospective analysis of 561 subjects aged > 65 yrs and 319 subjects aged < 35 yrs who were investigated in our Sleep Laboratory between 1992-2005 due to snoring or daytime sleepiness. They all underwent full polisomnography or a limited recording...
