we evaluate the presence of OSA in patients that have a computed tomography (CT) of the chest to rule out pulmonary embolism (PE) to determine if OSA constitutes an independent risk factor for PE.
The role of continuous positive airway pressure (CPAP) in cardiac function in patients with CSA and OSA has been studied with varying results. Nevertheless, it is not clear whether CPAP treatment for respiratory sleep disorders in CHF could slow down deterioration or improve the cardiovascular function. In an attempt to yield further insight into this subject, we undertook a multicentre study to analyze the role of CPAP therapy (optimal vs sham) in the LVEF and in other cardiac measurements in patients with CHF.Aim. We evaluated in a randomized multicentre placebo (sham-CPAP) controlled study the effect of CPAP treatment on the left ventricle ejection fraction (LVEF) among other cardiological related variables.
Obstructive sleep apnea (OSA) is associated with adverse cardiovascular outcomes, including acute myocardial infarction and stroke. Atherosclerosis is an important step for these events. Recent studies demonstrated the independent association between OSA and validated markers of atherosclerosis. However, the impact of treatment with continuous positive airway pressure (CPAP) on these markers is unknown. The purpose of this study is to determine whether CPAP therapy can reverses early signs of atherosclerosis in apparently healthy OSA patients.
The aim of this prospective study is to evaluate the results of polidocanol sclerotherapy of pharynx for OSAS & SS,to reduce pharyngeal compliance.
Obstructive sleep apnea is a common sleep disorder. It is known to be related with increased body mass, abdominal obesity, insulin resistance and hypertension. It is currently believed to be a feature of the metabolic syndrome. Other features of the metabolic syndrome-such as insulin resistace were found related to inflammation and inflammatory cytokines. Several polymorphisms in the genes that encode interleukin 6,inteleukin 10 and TNF-alpha have significant influence on the amounts of cytokine production. we thus hypothesize that polymorphisms related to increased pruduction are more common in subjects with OSA than in matched controls
This is a research study of the effect of treating laryngomalacia (floppiness of tissue on top of the voice box that can possibly block breathing) found in association with obstructive sleep apnea (blockage of breathing while sleeping). The purpose of this study is to determine which is the best treatment for children with obstructive sleep apnea and laryngomalacia: adenotonsillectomy alone or adenotonsillectomy with laser supraglottoplasty (removal of tissue on top of the voice box to open the airway).
The purpose of this study is to evaluate the efficacy and tolerability of Continuous Positive Pressure for SAOS in Down Syndrome patients.
Doxapram is used to stimulate respiration. For a given dose, the fluctuations in concentrations observed in infants' blood may be wide, leading to a risk of lack of efficacy or of toxic effects. Two factors are linked to these fluctuations: age and gender. The aim of this study is to compare a dosage regimen based only on patient's weight, to another one using a dosing chart taking into account weight, age and gender.
The infant car restraint devices are a critical part of infant safety during transportation. The crash tolerance and the critical safety features of each seat are well established. Infant transportation may be via a car seat or car bed. The effect of the sitting position on the airway is a concern in an infant with poor head control. Because of this concern, car seat tests during which oxygen saturation is measured, are performed on many low birth weight infants before discharge from the nursery. Indeed, a number of deaths have occurred in car seats probably related to airway obstruction. The relative effects of position on the ventilation need to be established. We propose to identify the relative changes in ventilation that are induced by position change during sleep. We will collect a broad array of high quality data that will identify these changes, and the most likely cause. Specifically, we will we screen 200 infants, with each infant assigned to the supine position, the car bed and the car seat. The order of these positions will be randomly assigned. Following data will be collected: 1. Relative changes in ventilation will be assessed by oxygen saturation measurement. 2. Respiratory movement will be measured in order to define the defect. 3. Once the data is collected, it will be sent for blind data analysis. 4. Once the data analysis is complete, the effect of position on ventilation will be established.
