Active clinical trials for "Sinusitis"

Based on the evidence for the "common pathway" in asthma presentation, our working hypothesis is that asthma severity and lack of control are related to the prevalence and severity of nasal and sinusal inflammatory pathology, and especially to chronic rhinosinusitis with nasal polyps.

The purpose of this study is to determine the clinical characteristic of recurrent acute rhinosinusitis in children.

The research at University of California Irvine, Beckman laser institute and Praxis Biosciences Incorporation, develope near-infrared trans-illumination methods. The optical imaging tool that can determine acute sinusitis and the response to treatment therapy.

Professor Hossam Haick from the Technion, developed an electronic nose for diagnosis of diseases via breath samples. Biomarkers from nose and sinuses and upper respiratory tract can be detected by "electronic nose". Identification of biomarkers from nose and sinuses and upper respiratory tract can differentiate between the subtypes of CRS (Chronic rhinosinusitis) and may serve as markers for disease (vs controls), of disease activity (predicting aggressive disease course, predicting Malignant vs Benign nasal "polyps", as inverted papillpma or carcinoma; predicting response to therapy (Steroid , Antibiotics, Nasal wash, Surgery).

The purpose of this study is to compare compliance between patients with Acute Bacterial Sinusitis (ABS) treated with Azithromycin SR 2.0 g single dose orally and those treated with Amoxiclav - 1000 mg twice daily 10 days for the empiric treatment of ABS in outpatient clinic practice.

To process blown nasal secretions from subjects with rhinosinusitis and to obtain a specimen by nasal lavage. To investigate the reliability and validity of the measurements we will determine their repeatability and compare them with those of nasal lavage in the same subjects.

The study serves to investigate the type and prevalence of non-rhinologic headaches seen through a academic otolaryngology practice.The study encompasses survey questionnaires, review of CT images, and physical examination/nasal endoscopy findings.

A single quality questionnaire evaluating the symptoms of chronic rhinosinusitis in children currently exists. It has been validated in English for children aged 2 to 12. It comprises five areas of quality of life, each rated by a score ranging from 1 to 7 : sinus infection, nasal obstruction, allergic symptoms, emotional distress and activity limitation, coupled with an overall assessment of quality of life with an analogue visual scale (score from 1 to 10). This SN-5 (sinus and nasal quality of life survey) score showed excellent statistics of reproducibility, internal validity and ease of response. It is currently used in several international publications evaluating chronic sinus pathology in children. The objective of the study is to validate the translation of the SN-5 questionnaire in French.

To analyse and describe sinus microbiota, during hard to treat (or refractory) rhinosinusitis, using culturomic and metagenomic methods (i.e. to culture on many different medium of culture to grow hard to cultivate bacteria + to sequence and analyse all DNA contained in samples). Samples are middle meatus swabs or pus aspiration, done during usually patient following.

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.
