Filter by:Randomised, placebo-controlled trial of continuous positive airway pressure therapy (CPAP) versus Provent® and Placebo-Provent® to define the effects of Provent® on the severity of obstructive sleep apnea, daytime symptoms as well as on measures of cardiovascular risk.
The purpose of this study is to evaluate the long-term efficacy, tolerance and compliance of ORM Narval Mandibular Repositioning Device (MRD) as a second-line treatment for patients with severe Obstructive Sleep Apnea Hypopnea (OSAH) syndrome who refuse or are intolerant to Continuous Positive Airway Pressure (CPAP) treatment.
Obstructive sleep apnea/hypopnea syndrome (OSAHS) is a highly prevalent disorder with multiple comorbidities. OSAHS is characterized by repetitive episodes of airflow reduction (hypopnoea) or cessation (apnoea) due to upper airway collapse during sleep. Its major risk factor is obesity. However, its pathogenesis is complex and multifactorial. Reduced upper airway muscle tonus and/or unstable neuromuscular output seem to be involved in this collapsus. A normal vitamin D status is necessary for normal muscle function and neuromuscular output. As obesity is associated with a high rate of hypovitaminosis D, it appears of interest to evaluate the effect of vitamin D supplementation on OSAHS patients with vitamin D deficiency.
Principal aim: To determine the prevalence of Sleep Apnea- Hypopnea syndrome in obese children. Secondary aim: 1. To fix the implication of the adenotonsillar hypertrophy, the obesity and the hormonal factors in the pathogeny of SAHS in children. 2. To determinate of clinical and neurophysiologic characteristics of childhood SAHS associated with obesity. DESIGN: A prospective transversal study.
Upper airway resistance during sleep can present with a range of symptoms from simple snoring (SS) through to severe obstructive sleep apnea (OSA). Pharyngeal narrowing or collapse leads to reduction or cessation in airflow during sleep, and is associated with loud snoring. The investigators hypothesized that regular singing exercises could strengthen pharyngeal muscles and/or increase their resting tone, and lead to an improvement of symptoms and thus quality of life in patients with all forms of snoring.
The sleep respiratory troubles (central apnea or CHEYNES-Stokes dyspnea) are frequent after stroke. The association of the sleep respiratory troubles with a reserved functional prognosis is debated. The purpose is to find out the frequency of the sleep respiratory troubles after stroke in a PRM department and to study their relationship with functional and neurological recovery.
Tonsil surgery for children suffering from obstructive sleep apnea have significant post operative morbidity including pain and occasionally bleeding. This morbidity is partly caused by post surgical inflammation. This inflammatory process can be quantified using various proinflammatory cytokines. the goal of this study is to objectively compare the inflammatory process after treatment of obstructive sleep apnea with different surgical approaches to the enlarged tonsils.
The literature does not discuss if the fast oral appliance titration (30 days period) in Obstructive Sleep Apnea Syndrome (OSAS) treatment, may improve subjects quality of life in such brief period. Temporomandibular dysfunction-related (TMD) is one of the most important side effects observed in OSAS treatment with oral appliance. Since the effectiveness of mandibular exercises in the control of TMD pain has already been verified, it may play a fundamental role in the support of the fast oral appliance titration.
This purpose of this study is to 1. Determine the change in endothelial dependent vascular reactivity and vascular properties 2. Determine the changes in monocytes activation 3. Determine the change in pro-inflammatory status 4. Investigate the effect of six-month CPAP therapy on the above changes in patients with OSA
The main purpose of this study is to measure the evolution of hemoglobin A1c level after treatment with CPAP in a cohort of type 2 diabetes mellitus patients with poor glycemic control and associated moderate or severe obstructive sleep apnea.
