#1
Chen Lin, Men-Tzung Lo, Christian Guilleminault
Patients with nasal flow limitation and upper airway resistance syndrome (UARS) during sleep can present with low blood pressure and disturbing symptoms associated with hypervagotony. We hypothesized that the dynamic changes of the autonomic system related to inspiratory flow limitation can be quantified by the developed analytic technique applied on beat-to-beat heart rate (RR intervals) and finger photoplethysmography (PPG). METHOD: A breath-by-breath investigation based on the Hilbert-Huang transform was performed to explore autonomic nervous system changes observed during inspiratory flow limitation...

OBJECTIVE: The association between restless legs syndrome (RLS) and obstructive sleep apnea syndrome (OSAS) has seldom been reported. There is one study reporting improvement of RLS symptoms severity in patients naive of treatment after initiation of continuous positive airway pressure (CPAP) for OSAS. The aim of this study was to evaluate the impact of the OSAS treatment in patients with previously diagnosed, clinically significant RLS in a usual clinical setting. METHODS: This was a retrospective study of RLS patients from a sleep clinic with a concomitant or subsequent diagnosis of OSAS...

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) has been associated with elevated biochemical markers of inflammation. Although the exact mechanism is unknown, both sleep deprivation and hypoxemia are believed to be important causative factors. YKL-40, also known as chitinase-like protein, has been shown to be related to various inflammatory conditions including atherosclerosis, diabetes, cancer, and asthma. The present study aimed to evaluate the relationship between YKL-40 levels and the Apnea Hypopnea Index (AHI) in patients with obstructive sleep apnea syndrome...

OBJECTIVE: To evaluate the clinical value of pulse oximetry watch (POW) for diagnosing pediatric Obstructive sleep apnea/hypopnea syndrome (OSAHS). METHODS: We selected 32 children (boys: 25, 4-16 years old) who came to the hospital for diagnosing OSAHS from July to October 2016. Polysomnography (PSG) and POW were used simultaneously and recorded the apnea hypopnea index (AHI), LSpO2, and ODI4. Pearson analysis, t test, and receiver-operating characteristic (ROC) were used to analyze the correlation between PSG-AHI and other indicators, the diagnosis accordance rate, and the sensitivity and specificity of POW, respectively...

BACKGROUND The objective of the present study was to investigate whether the analysis of magnesium (Mg), high-sensitivity C-reactive protein (hsCRP), and ischemia-modified albumin (IMA) concentrations can be used as a non-invasive and convenient method for diagnosing obstructive sleep apnea syndrome (OSAS). MATERIAL AND METHODS After polysomnography, venous blood was collected from 33 patients with OSAS and 30 control individuals. Serum levels of Mg, hsCRP, and IMA were investigated. The relationship between these factors and apnea-hypopnea index (AHI) was analyzed using the Pearson correlation coefficient...

BACKGROUND: Inflammation plays an important role in obstructive sleep apnea syndrome (OSAS). The objective of this study was to investigate the relationship of serum C-reactive protein(CRP), pentraxin-3(PTX-3), procalcitonin(ProCT), interleukin-33(IL-33) and its soluble receptor ST2 (sST2) with the syndrome severity and to show theirs importance as biomarkers. METHODS: This study comprises a total of 84 identical (sex and age wise) cases. Full-night polysomnography was performed in each patient...

Objectives: New non-invasive ventilation (NIV) modes can automatically adjust pressure support settings to deliver effective ventilation in response to varying ventilation demands. It is recommended that fixed expiratory positive airway pressure (FixedEPAP) is determined by attended laboratory polysomnographic (PSG) titration. This study investigated whether automatically-determined EPAP (AutoEPAP) was non-inferior to FixedEPAP for the control of obstructive sleep apnea (OSA) during intelligent volume-assured pressure support (iVAPS) treatment of chronic hypoventilation...

Recently, new conservative and non-resective surgical techniques, including palatopharyngeal surgical lifting and suspension (the 'Roman blinds technique') and modular barbed snore surgery (MBSS), have been successfully introduced for the treatment of obstructive sleep apnea syndrome (OSAS). This pilot longitudinal study describes our preliminary experience with the 'Alianza technique' (the simultaneous use of Roman blinds and MBSS) in mild to moderate OSAS patients with concentric pharyngeal collapse at the velum, previously documented by means of drug-induced sleep endoscopy...

BACKGROUND: Nasal continuous positive airway pressure (CPAP) in moderate-to-severe cases of obstructive sleep apnea cancause nasal discomfort and other undesirable problems. OBJECTIVE: The aim of our study was to test the effects of sodium hyaluronate on nasal problems that patients experienced in their daily lives, sleepiness, nasal resistance to airflow, nasal mucociliary clearance, changes in inflammatory markers, and compliance to CPAP in three groups of patients with obstructive sleep apnea syndrome on CPAP therapy...

OBJECTIVE: To report a case of corneal neovascularization with secondary lipid keratopathy in a patient treated with continuous positive airway pressure (CPAP) for obstructive sleep apnea-hypopnea syndrome (OSAHS). CASE REPORT: A 49-year-old male had been diagnosed with obstructive sleep apnea syndrome 10 years ago and has been treated with the application of a CPAP machine during night sleep ever since.

PURPOSE OF REVIEW: The management of children with Down syndrome as it pertains to the otolaryngologist continues to evolve. Obstructive sleep apnea (OSA) has dominated the recent literature, but other topics including hearing loss, swallowing, and perioperative considerations are also reported. RECENT FINDINGS: The prevalence of OSA in children with Down syndrome ranges from 57 to 73% in certain cohorts, and, whereas adentonsillectomy can decrease Apnea-Hypopnea Index, up to 80% may have persistent OSA...

Objective: To analyze the clinical significance of hypoxia index (HI) in assessing the severity of hypoxemia in obstructive sleep apnoea hypopnea syndrome(OSAHS). Methods: A total of 127 patients with a complaint of snoring visiting our hospital were recruited from February 2014 to January 2016. All patients received polysomnography (PSG) test. The PSG results were analyzed by a technician and the SpO(2) data were analyzed by a pre-designed computer software. The patients were grouped according to apnea hypopnea index (AHI) and lowest oxygen saturation (LSpO(2)) respectively...

Obstructive sleep apnea syndrome (OSAS) is known to be a risk factor for atherosclerosis (AS), derived from a series of chronic inflammatory reactions caused by hypoxia. However, the association between chronic inflammation and high blood pressure caused by hypoxia remains to be fully elucidated. The aim of the present study was to investigate the effect of continuous positive airway pressure (CPAP) therapy on inflammatory cytokines and AS. A total of 100 patients with OSAS and 50 healthy control subjects were enrolled...

Deficiency in the functioning of the genioglossus, which is one of the upper airway dilator muscles, is an important cause of obstructive sleep apnea/hypopnea syndrome (OSAHS). Estrogens have been reported to inhibit hypoxia-inducible factor-1α (HIF-1α) expression in hypoxia, regulating its target genes and exerting protective effects on the genioglossus in chronic intermittent hypoxia (CIH). This study aimed to investigate the role of 17β-estradiol (E2) and a resveratrol dimer (RD) on HIF-1α and the underlying mechanism...
