Filter by:The clinical hypothesis of this study is that a currently marketed mouthguard may also be able to reduce the symptoms of sleep-disordered breathing in children.
Introduction: The Upper Airway Resistance Syndrome (UARS) is a sleep disorder characterized by airway resistance to breathing during sleep that leads to arousals and daytime sleepiness. There are few studies about UARS treatment and there is not any gold standard treatment for it yet. Objective: Primary: To evaluate the efficacy of oral appliance on improving fatigue in patients with UARS. Secondary: Evaluate the effects of treatment with oral appliance (OA) in patients with UARS on sleepiness, mood, cognition, quality of life, metabolism and autonomic nervous system. Methods: Subjects with UARS (Apnea/Hypopnea Index - AHI - ≤ 5 events per hour of sleep and Respiratory Disturbance Index - RDI - > 5 events per hour or more than 30% of total sleep time with inspiratory flow limitation and with excessive daytime somnolence and/or fatigue) of both genders, with body mass index (BMI) lower than 30Kg/m2 and between 25 to 50 years of age will be included. Subjects will be randomly distributed in OA group and placebo (without treatment). At baseline evaluation, 6 months and 1 year after subjects will be submitted to sleep questionnaires, physical exam, otolaryngological evaluation, baseline polysomnography, Epworth sleepiness scale, Multiple Sleep Latency Test, fatigue scale, neurocognitive testing, autonomic nervous system analysis (heart rate variability) and metabolic evaluation. Mean and standard deviation will be used for descriptive statistical analysis if normal distribution, and median and percentiles (25%, 75%) for variables not normally distributed. To compare treatment groups T test (parametric) and Mann Whitney (non parametric) will be used. For adjusted analysis, linear regression analysis will be used.
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.
This study will examine whether treatment of inferior turbinates in patients with continued symptoms of obstructive sleep apnea, sleep related breathing disorder, snoring, disturbed sleeping, open mouth breathing, and upper airway resistance syndrome after tonsillectomy and adenoidectomy will improve these symptoms and should be included in the treatment paradigm for treatment of sleep related breathing disorders in infants, children, and adolescents.
This study is intended to compare intrathoracic pressure and respiratory effort data obtained by forehead venous pressure and respiratory movement (FVP/RM) with data obtained by the current gold standard, esophageal manometry. If this feasibility study validates the ability of FVP/RM data to quantitatively measure respiratory effort non-invasively, further studies will be performed to validate the utility of the ARES device in diagnosis of the UARS.
This is a pilot study to determine the usefulness of a newly developed, minimally invasive tongue suture procedure for people with obstructive sleep apnea.
Tongue exercises are described to improved snoring and acid reflux symptoms. Acid reflux treatment has been found to improve obstructive sleep apnea to a limited degree. Upper airway resistance syndrome is caused by resistance to breathing, leading to multiple respiratory event related arousals, leading to daytime fatigue and other various physical ailments. Tongue base or retrolingual collapse is implicated in upper airway resistance syndrome. We will measure sleep quality and quality of life indices before and after treatment for subjects that undergo tongue exercises only, acid reflux treatment only, and those that undergo both treatments.
