4 Clinical Trials for Various Conditions
Chronic rhinosinusitis is an inflammatory disease of the sinonasal mucosa with significant impact and limited treatment options. Chronic rhinosinusitis (CRS) poses an important public health problem and causes a large impact on individual quality of life. Studies of CRS have been limited by access to tissue, the complexity of the sinonasal physiology, a lack of available biomarkers, the absence of useful animal models, a paucity of cohorts with biological samples for analysis, and limited well-designed clinical trials or investigations of immune function. Therefore, novel strategies for identifying biological mechanisms underlying this disease are in great need. Using prospective samples from well characterized subjects, the investigators intend to profile the mucosa associated-bacteria in the nose and sinuses. In parallel, using sinus tissue from patients undergoing surgery, the site will interrogate the epithelium for mucosal immune function to understand host-microbe interaction. This study hypothesizes that the microbial profile of the sinuses initiates an immune responses which leads to chronic inflammation in susceptible people. This study would provide the first comprehensive data on what bacteria are present in the nose and sinus and could lead to important knowledge useful in sinonasal disease.
Laryngeal mask airways (LMA) have been shown to be a safe mode of airway management when delivering general anesthesia to patients during a variety of operative procedures. LMA's have been studied in a wide range of otolaryngologic procedures, and are generally safe and accepted by both anesthesia providers and surgeons alike. This study will aim to demonstrate the safety and efficacy of LMA for airway management during sinonasal surgery by directly comparing them to endotracheal intubation in a prospective randomized single-blind study.
The purpose of this study is to determine the most effective route to administer steroids to patients with chronic sinusitis, specifically a type of chronic sinusitis not associated with nasal polyps (CRSsNP). The investigators would like to better understand whether orally administered steroids results in superior results when compared with nasally sprayed steroids. The investigators propose to test the hypothesis that for patients with radiographically proven CRSsNP, routine medical therapy consisting of a short course of systemic corticosteroids is superior to topical corticosteroids for relieving inflammation and the symptoms of CRS.
The purpose of this clinical trial is to evaluate the effectiveness of a new surgical checklist in the setting of sinus surgery for patients with chronic rhinosinusitis (CRS) and to measure the frequency of compliance by surgical personnel at OHSU with specific daily safety protocols before and after introduction of the checklist. The investigators hypothesized that the use of an ESS specific surgical checklist will improve the frequency of compliance by surgical personnel at OHSU to internal safety concerns and protocols.
