Filter by:Removal of the adenoid and tonsils, known as an adenotonsillectomy (AT) is one of the most frequently performed surgical procedures in North America. The two most prevalent indications for this procedure in children are recurrent bacterial tonsillitis and obstructive sleep apnea (OSA). OSA is a common childhood condition that is characterized by upper airway obstruction, disturbed sleep and disrupted normal respiratory gas exchange. In the majority of children with OSA, overgrowth of the adenoid and tonsils is the primary underlying aetiology, making tissue removal via AT the standard of care. The purpose of this study is to evaluate the effectiveness of two different surgical techniques, electrocautery-tonsillectomy and coblation-tonsillotomy, in the treatment of obstructive sleep apnea (OSA) in children.
The study is a prospective field evaluation to assess the therapeutic value of the CPAP/autoCPAP Sandman in 24 new diagnosed Obstructive Sleep Apneic patients. Precisely, the study was designed to : - evaluate the therapeutic efficacy of the CPAP/autoCPAP Sandman device in improving sleep quality and normalozing respiratory events - determine the sensitivity and specificity of the device in adequately detecting respiratroy events - compare effective pressure Peff determined by the device and during manual titration - compare the impact of the two-speed descent pressure algorithm
The aim of this study are (1) To genome-wide profile the gene expression patterns of peripheral blood mononuclear cell (PBMC) in patients with obstructive sleep apnea (OSA) (2) To profile the gene expression patterns change before and after treatment with continuous positive airway pressure (CPAP) (3) To correlate the altered gene expression with the severity of the disease and outcome of OSA patients
Specific Aim 1. To identify specific SNPs of HIF-1 gene related to cardiovascular disease in OSA patients (CVD-OSA) 2. To assay the functional activity of high risk SNPs of HIF-1 on the transcription of VEGF gene 3. To confirm that the serum level of VEGF in CVD-OSA patients with high risk SNPs of HIF-1 are higher than CVD-OSA patients without
The purpose of the study is to determine the effect on mood and anxiety symptoms of adding CPAP to the psychiatric treatment of patients with TRD (treatment resistant depression) and associated OSA (obstructive sleep apnea).
Investigate the role of clinical parameters in predicting the severity of obstructive sleep apnea
Individuals with obstructive sleep apnea syndrome (OSAS) are at high risk for cardiovascular morbidity and mortality. The effect of long-term nocturnal therapy with continuous positive airway pressure (CPAP) on daytime baroreflex sensitivity (BRS), a predictor of cardiac death, was investigated in OSAS patients.
The purpose of this study is to define the mechanism(s) through which Obstructive Sleep Apnea/Hypopnea (OSAH) promotes abnormal metabolic processes which characterize the metabolic syndrome. The investigators hypothesize that the sleep fragmentation and intermittent sleep hypoxia which occur in OSAH patients promote oxidative stress and inflammation which in turn lead to insulin resistance, dyslipidemia, abnormal vascular reactivity and other processes which are consistent with the metabolic syndrome.
