OBJECTIVES To evaluate ocular surface health in obstructive sleep apnea syndrome (OSAS) and to investigate the tendency of these patients toward dry eyes. MATERIALS AND METHODS Fifty patients who underwent polysomnography and were diagnosed with OSAS and 50 normal control subjects were compared with respect to ocular surface disease index (OSDI), Schirmer I test and tear film break-up time (T...

OBJECTIVE To investigate the seroprevalence of Helicobacter pylori (H. pylori) in patients with obstructive sleep apnea syndrome (OSAS), and to determine any association between H. pylori infection and severity of OSAS. METHODS Two hundred and forty-three subjects were recruited in this cross-sectional study at the Department of Respiratory Medicine in the West China Hospital, Sichuan, P. R. ...

Background Heart rate variability (HRV) represents the sympathetic nervous system activity induced by apnea or hypopnea events among OSAS patients. However, few studies have been conducted to clarify the association between HRV parameters and polysomnography (PSG) diagnostic indices. In our study, we postulate that the prevalence of cardiac arrhythmias is associated with OSAS, and HRV parameter...

background and objective: depression is commonly reported in patients with obstructive sleep ap- nea/hypopnea syndrome (osas). we aimed to assess the association between osas severity and depressive symptoms in patients with osas. materials and methods : a total of 337 patients with symptoms of osas were visited for psychological testing prior to beginning diagnosis for the syndrome between 201...

Obstructive sleep apnea syndrome (OSAS) is commonly associated with endothelial dysfunction, atherosclerosis and cardiovascular disorders. On the basis of this observation, our aim was to examine the oxidative status and the matrix metalloproteases (MMP) profile in a group of subjects with OSAS. We enrolled 48 subjects with OSAS defined after a 1-night cardiorespiratory sleep study, who were su...

Aim. To evaluate the retinal nerve fiber layer (RNFL) thickness in patients with obstructive sleep apnea syndrome (OSAS) by optical coherence tomography (OCT). Materials and Method. We studied 43 new diagnosed OSAS patients and 40 healthy volunteers. Patients underwent an overnight sleep study in an effort to diagnose and determine the severity of OSAS. RNFL analyses were performed using Stratu...

BACKGROUND Relationships between exhaled breath condensate (EBC) and serum cytokines and apnea-hypopnea index (AHI) in patients with excessive daytime sleepiness and loud snoring were evaluated for their potential to predict the severity of obstructive sleep apnea syndrome (OSAS). METHODS Non-smoking patients with suspected OSAS who had undergone polysomnography (PSG) were selected until 22 n...

OBJECTIVE The current study aimed to investigate stages of reproductive aging as an associated factor for obstructive sleep apnea syndrome (OSAS) among women in a representative sample of Sao Paulo, Brazil. METHODS Four hundred seven women underwent clinical evaluation, polysomnography, and biochemical analysis. Stages of reproductive aging were defined as premenopause, early postmenopause, a...

Obstructive sleep apnoea syndrome (OSAS) might be a cause of heart failure. The present study aimed to assess left ventricular mass and myocardial performance index (MPI) in OSAS patients. A total of 67 subjects without any cardiac or pulmonary disease, referred for evaluation of OSAS, had overnight polysomnography and echocardiography. According to apnoea-hypopnoea index (AHI), subjects were c...

background: obstructive sleep apnea syndrome (osas) is a common sleep disorder characterized by repeated upper airway obstruction during sleep. while respiratory pauses followed by loud snoring and daytime sleepiness are the main symptoms of osas,the patients may complain from sleep disruption, headache, mood disturbance, irritability, and memory impairment. however, the association of sleep ap...
