Filter by:The purpose of this research study is to test whether treatment with isosorbide mononitrate will improve left ventricular hypertrophy ("thickening") which puts people at risk for developing heart failure. Once it develops, heart failure is a very serious condition and thus it is important to find ways to prevent it from happening. The investigators have reasons to believe that dilating the blood vessels with this specific medication will improve the thickening of the heart, which increases the risk of heart failure.
Obstructive sleep apnea (OSA) in children is a disorder of breathing during sleep characterized by prolonged partial upper airway obstruction and/or intermittent complete obstruction (obstructive apnea) that disrupts normal breathing during sleep1. The condition occurs in 2-5% of children and can occur at any age, but it is most common in children between the ages of 2 to 62,3. Untreated OSA is associated with lung disease, heart disease, growth delay, poor learning and behavioral problems such as inattention and hyperactivity. The most common underlying risk factor for the development of OSA is enlargement of tonsils and adenoids. Given the potential risk of complications associated with surgery of the tonsils and adenoids, medications to shrink the adenoids without requiring surgery have been considered, in particular intranasal corticosteroids (INCSs) which is a nose spray. A recent Cochrane systematic review suggested a short-term benefit of INCSs in children with mild to moderate OSA4. The authors recommended that further randomised controlled studies were required to evaluate the efficacy of INCSs in children with OSA. In particular they recommended that future studies should employ sleep studies to look for any improvement with INCSs, and should include children with more severe OSA, as these are the patients at the greatest risk of complications of surgery and would benefit most from a non-surgical treatment. The purpose of this study is therefore to explore the efficacy of INCSs in children with the full spectrum of OSA severity, including sleep study analysis., and longer term follow-up.
The purpose of the study is to determine whether the ability of MEK162 to antagonize MEK activation in NS HCM patients, who usually have upstream mutations in the Ras-Raf-Mek-Erk pathway that lead to MEK activation, would be beneficial over a 6 month treatment period in hypertrophy regression.
This study will consist of middle-aged Caucasian non-failing subjects with high blood pressure who are homozygous for a gene that confers increased risk of developing heart failure, the Glycine 83 variant of the Ka renal chloride channel (ClC-Ka Gly/Gly 83), or middle-aged Caucasian non-failing hypertensive subjects who lack the heart failure risk gene, the wild-type Arginine 83 Ka renal chloride channel (ClC-Ka Arg/Arg 83). Subjects on standard therapy for high blood pressure with an angiotensin converting inhibitor (ACEI) or angiotensin receptor blocker (ARB) will be randomized to additional treatment with eplerenone (an aldosterone antagonist) or placebo, and assessed for changes in echocardiographic left ventricular hypertrophy (LVMI). Secondary endpoints will assess left ventricular remodeling and other echocardiographic variables. The investigators hypothesize that subjects homozygous for the CLCNKA risk allele will have a greater response to eplerenone in terms of reductions in LVMI than those lacking the risk allele.
The ultimate goal of this work is to establish a method for control bleeding after tonsillectomy in awake children. Treatment of post-tonsillectomy bleeding in children typically requires general anesthesia with currently used electrocautery techniques. Micropolysaccharide hemosphere technology is a unique absorbable agent that helps clot form. These hemospheres consist of 100% purified plant starch that enhances natural clotting by concentrating blood solids such as platelets, red blood cells, and blood proteins on the particle surfaces to form a gelled matrix. This device provides painless, non-irritating control of bleeding, and has been used effectively for control of nosebleeds in awake adult patients. This device, however, has not been tested in the tonsillar fossae in children; thus, this study is performed to determine if at least 50% of children with bleeding tonsillar fossae can be spared rescue treatment with electrocautery.
The purpose of this study is to determine the genetic basis of cardiomyopathies and heart failure.
This study assesses the intervention with antifibrotic agents, specifically interferon (IFN) to reduce the magnitude and duration of hypertrophic scar. Burn patients with hypertrophic scar are randomly assigned to either an intervention IFN group or a placebo control group by subcutaneous injection three times a week. Patients are assessed using cutometer, mexameter, standardized photography, urinalysis, blood work, tissue biopsies and the Vancouver Burn Scar Assessment (VBSA) which rates selected HTS based on color, vascularity, height, pliability, itchiness and pain sensitivity. Once on treatment patients are assessed monthly for the six month treatment period.
The purpose of this research study is to further establish the diagnostic use of magnetocardiography (MCG) in patients with hypertrophic cardiomyopathy (HCM). The use of MCG has not been extensively studied in these patients. This pilot study will serve to further characterize abnormalities found on MCG in comparison to patients without hypertrophic cardiomyopathy. Additionally, the study will be used to understand whether MCG has any additional diagnostic utility in offering clinicians insight on the patient's disease state, thereby aiding in the development of treatment plans. This research study is designed to test the effectiveness of the investigational use of magnetocardiography in patients with hypertrophic cardiomyopathy. The device itself has been approved by the U.S Food and Drug Administration (FDA).
This is a randomized, double-blind, placebo-controlled study to document the long-term effect of treatment with mometasone furoate nasal spray in moderate to severe adenoids hypertrophy as reflected by the need for removal of the adenoids within one year of the treatment regimen. Subjects will be assigned treated with either mometasone furoate nasal spray or placebo for 3 months. Subjects will be followed for an addition 12 months. Serious AEs will be followed starting first dose-till 30 days after study treatment period completion. This study was terminated - Please see "P04367 - Lebanon"
The purpose of this study is to evaluate a new method of hemostasis, floseal gel, in tonsillectomy and adenoidectomy, with the goal of decreasing post operative and intraoperative morbidity.
