Data of 18 patients with obstructive sleep apnea syndrome (OSAS) on therapy with continuous positive airway pressure (CPAP) (with good efficacy) and with the Velumount® device were collected by respiratory polygraphy, blood pressure measurement, questionnaires, and neuropsychological tests to compare for the first time the effects of the Velumount® device to the one of CPAP therapy. Number of s...

OBJECTIVE To validate the BREAS SC20 (Breas Medical AB, Mölnlyke, Sweden) polygraphic screening device, comparing it with conventional polysomnography (PSG), in the diagnosis of sleep apnea-hypopnea syndrome. A validity study of the diagnostic test was carried out at the sleep clinic of a tertiary hospital. PATIENTS AND METHODS Seventy patients clinically suspected of sleep apnea-hypopnea syn...

Background and Objective: Obstructive sleep apnea (OSA) is the most common type of sleep-disordered breathing. Multivariable apnea prediction (MAP) index consists of three questions about the frequency of OSA symptoms plus body mass index (BMI), age and sex that categorizes the patients to low and high risk for OSA using a formula. Objective MAP index was calculated by discounting the questions...

Background: Many reports are available about the increasing rate of mortality due to overuse of opioids. It has been suggested that sleep apnea can be a cause of mortality because of overuse of opioids. Opium use is common in Iran. This study aimed to assess the effect of opium on polysomnographic findings in opium addicts with sleep apnea syndrome. Materials and Methods: In this prospective ca...

Aim: To investigate whether obstructive sleep apnea (OSA) patients present different behaviors of mandible movements before and under CPAP therapy. Materials and Methodology: In this retrospective study, patients were selected according to inclusion criteria: both the diagnostic polysomnography recording showing an OSA with an apnea-hypopnea index (AHI) greater than 25 (n/h) and the related CPA...

Objective: This study aimed to investigate the sleep quality and sleep respiratory conditions at night in patients with various level of gastroesophageal reflux disease (GERD) before and after conventional treatments. Methods: 40 patients with GERD were further divided into the non-erosive reflux disease (NERD) group and the reflux esophagitis (RE) group. 20 healthy people were enrolled as cont...

Sleep disorder breathing is characterized by repetitive upper airway obstruction and consequent oxyhaemoglobin desaturation during the deeper stages of sleep. The disorder is due to combination of both abnormal upper airway anatomy and yet to be determined afferent/efferent somatosensory loop. Apnea is defined as a cessation of airflow (breathing) lasting for at least 10 seconds. Hypo-apnea is ...

OBJECTIVE Obstructive sleep apnea syndrome (OSA) leads to a deterioration in cognitive functions, with regard to memory and executive functions. However, few studies have investigated the impact of treatment on these cognitive functions in elderly subjects. METHODS The study was conducted in a large cohort of subjects aged 65 years or older (the PROOF cohort). Subjects were not diagnosed or t...
