Filter by:Analysis of differential gene expression in patients with chronic rhinosinusitis without polyps compared to unaffected patients. Correlation of abnormal gene expression with surgical outcomes.
This study proposes to develop and validate a new instrument designed to measure facial and nasal discomfort related to chronic sinusitis. The second phase of the study will be to use this instrument to measure correlation with sinus computed tomography (CT) scans.
The study examines the biochemistry underlying human olfaction in both normal and diseased states. The study aims are: 1. to determine the levels of cAMP in olfactory tissue from people with chronic rhinosinusitis and other nasal disorders. 2. to correlate preoperative olfactory function with cAMP levels from biopsied olfactory tissue. 3. to determine odorant and pheromone-mediated activation of cultured human olfactory sensory neurons using calcium imaging and 4. to determine odorant and pheromone-mediated activation of cultured human olfactory sensory neurons using "smell-chip" technology.
Chronic rhinosinusitis (CRS) is the most common chronic medical condition that affects Americans between 18-44 years of age. While significant advances have been made in the understanding of the molecular pathogenesis underlying many subtypes of CRS, this has not translated into widespread changes in how physicians manage adult or pediatric CRS. The focus of this study is intended to develop testing methods to improve the objectivity and specificity of diagnosis and allow for individualized therapy with less invasive, customized treatments instead of the traditional, empiric based, and radically exenterative therapies commonly employed in clinical practice. Specifically, it is now known that many patients with CRS have a greater concentration of non-typeable Haemophilus influenzae (NTHI) in the bacterial biofilms located within their sinus cavities compared to healthy patients. The specific hypothesis behind the proposed research is that the presence of NTHI biofilms, which are known to be highly recalcitrant, are positively correlated with the development of CRS and that unique lipooligosaccharides and inflammatory byproducts obtained from nasopharyngeal lavage fluids and/or swabs of sinus secretions may be used as a non-invasive biomarker for CRS. As a result, patients with symptoms of CRS specifically associated with NTHI biofilms could possibly obtain a non-invasive test in the physician's office that would allow the clinician to make a more accurate diagnosis and objectively follow each patient's responsiveness to customized therapy.
The investigators are looking at the effects of baby shampoo nasal irrigation on the movement of mucous in the nose in patients who have undergone sinus surgery for chronic sinus problems.
The purpose of this study is to evaluate efficacy of azithromycin prophylaxis in preventing recurrent acute sinusitis in children.
A non-randomized, multi-center, prospective, clinical study intended to evaluate the safety and efficacy of balloon sinuplasty devices in pediatric patients with longstanding sinusitis following failed medical management.
Endoscopic sinus surgery will be performed either in the physician's office or in the operating room (OR). Patients treated in the physician's office will have endoscopic sinus surgery performed with balloon sinuplasty devices. Patients treated in the OR will have endoscopic sinus surgery performed with or without balloon sinuplasty devices.
Question: Is the effect of therapeutic ultrasound equally effective to antibiotic for treatment of sinusitis? Design: A randomized clinical trial with concealed allocation, self-assessment by the subjects and intention-to-treat analysis.
For each patient, an initial visit and at least one follow-up visit at the end of treatment should be documented by the treating physician in the case report form.
