View clinical trials related to Chronic Rhinosinusitis.
Filter by:The purpose of this study is to compare the bacteria, fungi, and viruses that are present in the sinuses of patients with chronic rhinosinusitis to patients without sinus disease using a new technology, called a microarray, that will allow more accurate identification of microorganisms than current laboratory methods.
Chronic rhinosinusitis (CRS) is a common health condition in the United States resulting in more than 200,000 surgical procedures annually. The field of rhinology has had two major advances which the investigators believe make more accurate prediction of postoperative outcome possible thereby offering the potential of reducing the frequency of unsuccessful surgical procedures. The first advance is the development of validated disease-specific quality of life instruments for measuring outcome of CRS management. The major medical societies now recognize disease-specific quality of life as the gold standard for assessing outcomes in this disease and for the purposes of this study, the investigators define surgical outcome as change in disease-specific quality of life (QOL). The second advance is the better understanding of the pathological process resulting in CRS. The previous construct defined this disease as anatomic obstruction of the sinuses and their secretions. This was thought to be best measured by CT scan which has been the main method of attempting to select the best candidates for surgery. The investigators hypothesize that utilizing this new conceptual framework, the investigators can better predict surgical outcomes. The investigators will examine several preoperative factors and their relationship to surgical outcome. The factors to be examined include measures of the pathophysiological components of inflammation and anatomic obstruction as well as preoperative extent of disease as measured by preoperative disease-specific quality of life. The investigators hypothesize that these factors provide complimentary information that may be variably expressed in individual CRS patients. Therefore, the investigators hypothesize that a novel integration of multiple preoperative factors will form a useful predictive model of surgical outcome. Finally this prospective study provides the opportunity to add to the field by identifying potentially novel risk factors and comorbidities as well as study secondary outcomes of sinus surgery including olfactory function and general health related quality of life in a systematic manner.
Chronic sinusitis is reported to be one of the most widespread disorders in the United States. It can be caused by a variety of reasons such as allergy, infection and/or defects in T-cells which help regulate immune function. Medication and other costs related to treatment of nasal and sinus infections are estimated to be more than $60 million annually putting a considerable strain on the economy of health care. Probiotics are live microorganisms that are normally present in the gut of a healthy individual. They are also known as "friendly bacteria" and have been used to help maintain the normal functioning of the immune system. They are safe and are commercially available in the form of yoghurt, sachets, chewable tablets or flavored capsules. Since a number of nasal and sinus disorders are related to allergy and improper functioning of the immune system, we hypothesize that regular use of probiotics may help improve chronic nasal and sinus symptoms by boosting immune responses. The project we propose is novel because it would be the first study evaluating the usefulness of probiotics for the larger population having chronic sinusitis rather than those having only allergic symptoms. We aim to assess whether regular use of probiotics will help improve symptoms of chronic sinusitis and will have a greater effect than placebo in this regard.
This study will compare nasal saline irrigation with nasal saline spray for the treatment of chronic nasal and sinus symptoms. Participants will complete a questionnaire regarding their nasal and sinus symptoms and will be randomly assigned to one of the treatment groups. Each participant will be instructed on how to perform daily nasal treatment.The subjects will complete follow-up surveys at regular intervals to assess any change in their nasal symptoms after starting nasal saline treatment. Participants may take their usual medications for sinus symptoms during their participation in the study.
Rhinosinusitis disorders are often associated with Cystic Fibrosis. They can restrict quality of life enormously and give cause to repeated ENT surgery. The basic defect in CF is a dysfunction of Chloride channels in exocrine glands, leading to retention of secretions and consecutive chronic inflammation with bacterial superinfections. The prospective placebo controlled cross-over study aims at the evaluation of the efficacy of a nasally inhalation of Pulmozyme with respect to mucus retention and resulting inflammation.
