Filter by:This single-site, within-subject experimental basic research study is designed to analyze the hypothesis that allele-specific expression of the bitter taste receptor T2R38 in taste tissue of individuals heterozygous for the taste receptor gene TAS2R38 correlates with that in nasal epithelium, and is responsible for differences in acyl-homoserine lactone-induced respiratory defenses. Subjects will include 100 predominantly European adults without chronic rhinosinusitis who will be undergoing a sinonasal procedure for reconstructive purposes. All subjects will provide saliva samples for genotyping, from which 25 subjects heterozygous for TAS2R38 (AVI/PAV) will be identified. These individuals will be asked to complete a beverage frequency questionnaire and taste test prior to the procedure that will evaluate for a number of compounds, among them bitter ligands specific to T2R38. Their tongue will also be photographed to evaluate the anatomy of their fungiform papillae, the mushroom-like structures on the tongue which contain taste buds. Subjects will subsequently provide nasal epithelium and taste tissue, which will be processed to 1) evaluate for allele-specific expression of TAS2R38 mRNA in both the taste and nasal tissue, with the nasal tissue concurrently being cultured in an air-liquid interface system to 2) assess the AHL-induced respiratory defenses of ciliary beat frequency (CBF) and nitric oxide (NO) production. Should subjects require a subsequent sinonasal procedure for clinically-determined reasons, taste and nasal tissue will again be obtained and analyzed for TAS2R38 mRNA, allowing for 3) longitudinal evaluation of mRNA expression level.
Single-center, prospective, placebo controlled trial of tolerability and safety of low-concentration SinuSurf sinus irrigation solution in normal subjects. Forty (40) healthy subjects aged 18-65 will be enrolled in the study.
Inflammatory paranasal diseases are among the most common diseases in ENT In Russia, puncture method has been conventional approach to treatment of maxillary sinusitis. However, this procedure is associated with a number of drawbacks A promising trend for the treatment of purulent sinusitis is a reasonable antibacterial therapy Fluoroquinolones, particularly levofloxacin, are highly active against pneumonocci and are more active vs. the drug products of the second generation against intracellular agents (Chlamydia spp., Mycoplasma spp., M. tuberculosis, rapidly growing atypical mycobacteria (M. avium, etc.). Due to high activity against the agents causing bacterial upper and lower respiratory tract infections they are sometimes called "respiratory" fluoroquinolones
The goal of this research project is to explore the impact of the addition of budesonide to high-volume, low-pressure nasal sinus saline irrigation (aka "Neti-Pot"-type systems) for patients with chronic rhinosinusitis with or without nasal polyps.
Chronic rhinosinusitis without polyposis (CRSsP) is a very common condition that occurs when the lining of the sinuses becomes persistently irritated. Standard management options include topical steroids, antibiotics and surgery, but treatment-resistant CRSsP is frequently encountered. Bacterial biofilms are routinely detected within the nasal mucosa of CRSsP patients and are now thought to play an important role in the protracted nature of the disease. Colloidal silver is a widely used naturopathic agent that has recently been shown to eliminate bacteria, and in particular in vitro sinusitis biofilms, in laboratory studies. Although silver is currently used in a variety of chronic wound therapies, it has not yet been formally studied in people with CRSsP. It is our intention with this project to determine whether colloidal silver is a useful treatment strategy for patients with refractory CRS.
The study should create data for the selection of a clinically relevant endpoint to assess the potential of Buparid/PARI SINUS to postpone sinus surgery in patients with chronic Rhinosinusitis.
The study should create data for the selection of a clinically relevant primary endpoint to assess the efficacy and safety of Buparid/PARI SINUS as compared to Budes Nasal Spray in the therapy of chronic rhinosinusitis (CRS) with polyposis nasi in adult patients. Ideally, the selected parameter should allow a correlation between an objective methodology and the clinical outcome of the study patients.
The general hypothesis is that delayed antibiotic treatment strategy present similar effectiveness, when compared with non-prescription of antibiotics or the prescription of antibiotics, in the non-complicated acute respiratory tract infections in pediatric patients.
The aim of this study is to determine what the ideal frequency of high-volume sinonasal saline irrigation in the early postoperative period following ESS for medically refractory CRS. We will evaluate once, twice, and three times daily frequency sinonasal saline irrigation protocols. Our hypothesis is that three times a day sinonasal saline irrigations for the first week is ideal with no difference between frequencies after 1 week.
