Active clinical trials for "Nasal Polyps"

Oral corticosteroids are commonly utilized for the management of chronic rhinosinusitis with and without nasal polyps (CRSwNP and CRSsNP, respectively). Although strong evidence supports the benefit of routine and perioperative oral corticosteroids for CRSwNP, there is limited evidence to support their utility for CRSsNP. The investigators intend to perform a randomized, double blind, placebo controlled clinical trial to investigate the impact of steroids used within 2 weeks prior to surgery for CRSsNP. Patients with CRSsNP that present to the investigators office will be included if they have failed maximal medical management and have elected to undergo endoscopic sinus surgery (ESS) after July 1, 2014. The investigators hypothesis is that oral corticosteroids given 2 weeks prior to surgery will improve subjective and objective outcome measures.

Introduction: Rhinitis, sinonasal polyposis (SP) and asthma are diseases whose pathogenesis is based on inflammation. This will determine the presence of disease, its evolution and its treatment. It is therefore very important to develop and validate methodologies that allow us to noninvasively detect inflammation of the airways. Thus, just as exhaled nitric oxide (FeNO) has been studied as an important non-invasive marker of inflammation of the lower airways, nasal nitric oxide (nNO) may be a good marker of nasal inflammation. Furthermore, the electronic nose is an electronic nanosensor device capable of detecting specific volatile organic compounds (VOCs) that can be used as a non-invasive biomarker of biochemical processes in different diseases whose pathophysiology is also based on inflammation. Objective: To determine reference values of nNO and different patterns of VOCs in healthy individuals, individuals with allergic rhinitis (AR) and non-allergic rhinitis and individuals with SP and asthma. Methodology: Prospective, controlled study. Four groups will be included: Healthy subjects, patients with AR, non-allergic rhinitis and patients with SP and asthma (n=252). Prick-test to pneumoallergens will be performed. Determination of FeNO, nNO, lung function tests, measurement of VOCs by the electronic nose and blood samples will be taken. Bilateral nasal endoscopy and sample collection using the technique of brushing of mucosa and the placement of filter papers, for the study of nasal cytology and mediators of inflammation.

Functional endoscopic sinus surgery (FESS) is indicated in diseases such as chronic sinusitis refractory to medical treatment, nasal polyposis, mass lesions in the nasal cavity. The purpose of this study is to determine whether tramadol and metoprolol are as effective as remifentanil in providing controlled hypotension during FESS.

This study aimed to show the effect of sphinopalatine ganglion blockade on surgical field, hemodynamics and postoperative pain in FEES operation.

The main objective of this study is to compare the effects of RESPIMER® NetiFlow® solution and device versus saline solution (0.9% NaCl), the standard treatment, used with RESPIMER® NetiFlow® device, both used postoperative care, in the context of ethmoid sinus surgery, at 14 days post-surgery.

Hippo-YAP pathway is a newly discovered pathway controlling the growth, and plays important roles in the regulation of stem cell function and tissue regeneration. Previously we found that a higher expression of YAP in NP, and LPS was able to activate the hippo-YAP pathway in NESCs. Thus, we hypothesize that the aberrant proliferation and differentiation of NESCs could be regulated via the hippo-YAP pathway.

The purpose of this study is to determine whether prednisone is effective in the treatment of chronic rhinosinusitis without nasal polyps in adult patients.

To detect the effect of hypertonic saline and fluticasone sprays on computed tomography scan of paranasal sinuses of patients having chronic sinusitis and/or nasal polyps.

The aim of this study is to evaluate the effect of middle turbinate Radio Frequency (RF) turbinoplasty with middle turbinate resection and medialization

Impaired olfaction is one of the major complaints of patients with nasosinus polyposis, with nasal obstruction. In case of failure of medical treatment for patients with polyposis nasosinusal, they may use endoscopic surgery nasosinusal. Before surgery, 73% are hyposmic or anosmic, compared to 43% after surgery. Persistence of hyposmia or anosmia despite the removal of polyps can be explained by mechanisms inflammatory in the mucous membrane of the olfactory cleft. In addition, studies in mice have shown a degeneration of primary olfactory neurons at the level of the olfactory mucosa in connection with directly with TNF alpha, a pro-inflammatory molecule.
