Active clinical trials for "Sinusitis"

Rhinosinusitis is a common clinical problem with significant morbidity which alters patients' quality of life that has its effect on 1 out of 7 adults. It has been found that rhinosinusitis accounts for almost 26 million clinics and emergency visits per year in United states .Nasal irrigation is standard management used to treat a variety of sinonasal diseases. Furthermore, nasal irrigation decreases the need of usage other medications in rhinosinusitis .Hence, it is considered safe, inexpensive, and easy to use with no evidence of major adverse effects .Up to our knowledge, there is no clear guideline in which type (isotonic saline vs hypertonic saline) and frequency (times per day) of nasal irrigation are superior and better.

Before performing endoscopic sinus surgery (ESS-Endoscopic Sinus Surgery), every candidate for surgery is referred to perform a sinus CT scan of the sinuses. Because of the complicated anatomy of the sinuses and their proximity to vital organs such as the brain, eye, and carotid artery, the surgeon use the CT imaging during surgery to adjust the anatomy and to avoid complications such as blindness, brain damage and massive bleeding (0.3%). Sometimes the CT is integrated into a navigation system, although there is no evidence that the use of navigation systems reduces the rate of complications. The aim of our study is to examine whether ESS can be performed in chronic sinusitis patients using MRI, with CT being used as a backup only.

Chronic Rhinosinusitis (CRS) is a common disorder of the nose. The current practice at St Paul's Sinus Centre is to prescribe budesonide via the mucosal atomization device or impregnated saline irrigation. Both have shown to be a safe method of administration. A previous study demonstrated a 6% elevation in intraocular pressure and 3% prevalence of asymptomatic AdrenoCorticoTropic Hormone-Axis (ACTH) suppression. However, a baseline measurement was not conducted to ascertain the correlation of these findings with the medication. Therefore, the investigators aim to conduct baseline measurements of IntraOcular Pressure (IOP), ACTH-axis function, and Dual Energy X-ray Absorptiometry (DEXA) scan and obtaining regular measurements of these variables within a 12-month period to further ascertain these previous findings.

To assess the efficacy of intra-sinus installation of a poloxamer gel that releases antibiotics and corticosteroids topically after balloon sinuplasty in chronic sinusitis patients with or without polyps. This is a single-blinded Randomized Control Trial study, in which every patient receives active gel on one side and placebo on the other (L or R to be randomly selected).

Despite the common use of oral steroids in the management of chronic rhinosinusitis (CRS), the natural history and efficacy of this treatment modality has not been fully elucidated. Specifically, patients who have undergone prior ESS and have recalcitrant CRS, the natural history of endoscopic improvement and quality of life (QoL) outcomes, following an oral steroid taper, is poorly defined. The purpose of this non-randomized single-arm clinical trial is to evaluate the effectiveness of an oral steroid taper in improving endoscopic grading, QoL, and olfactory function as well as defining the duration of improvement, in patients with recalcitrant CRS with prior endoscopic sinus surgery (ESS).

The purpose of this study is to see if a protein in blood, called periostin, can determine if patients have chronic sinusitis. This protein is in everyone's body, but the level of the protein may indicate certain conditions such as chronic sinusitis. The investigators are interested in testing levels of periostin to see if they are higher or lower than patients without chronic sinusitis, just as periostin is higher in patients with asthma. All patients enrolled in this study will have chronic sinusitis without asthma.

This is a cross-sectional, non-interventional study, consisting of three study arms, (1) Full Characterization (AIMS-Full), (2) Surgery Arm (AIMS-OR), and (3) Mucus Collection (AIMS-M). Participants will be recruited and enrolled in either AIMS-Full or AIMS-OR (based on participant availability). Participants who complete the initial characterization study (either AIMS-Full or AIMS-OR), may also go on to participate in the AIMS-M arm, which focuses mainly on sample collection. Participants who choose not to participate in either characterization arm are able to enroll directly into AIMS-M for sample collection only.

The purpose of this study is to investigate the relationship between viral infections of the upper respiratory tract, perturbations of the nasopharyngeal microbiome in children, and the risk of acute bacterial sinusitis over a one year period. The investigators will determine the incidence of acute bacterial sinusitis post viral upper respiratory infection and identify the viral antecedent infections and other risk factors which predispose to infection and ultimately design strategies to reduce the burden of disease and antimicrobial resistance.

A prospective, single centre, single arm study designed to collect clinical data on PerClot when used in subjects undergoing endoscopic sinus surgery.

Chronic rhinosinusitis (CRS) is defined according to the French society of otorhinolaryngology as chronic non-mechanical damage to the nasal structures, excluding infectious damage to the sinus structures. The duration of the chronic impairment must be at least 12 consecutive weeks. It causes many symptoms such as rhinorrhea, nasal blockage and anosmia. It is a poorly understood pathology that affects a large part of the population. Its prevalence has increased significantly over the past 30 years. It affects about 11% of the population in Europe. It has become one of ten high-cost medical conditions for employers. Initially, it was accepted that CRS was due to chronic nasal infection. It is very debilitating for patients leading to a major consultation with practitioners (general practitioners and ENT specialists). Many treatments are used such as nose washes, nasal or oral corticosteroids, antibiotic therapy or even surgical management is possible. Thèses treatments allow an improvement in the symptomatology but no treatment allows a stable result over time, making long-term treatments essential. Today, it is recognized that CRS has a multifactorial etiology including inflammatory processes, hyperresponsiveness of the nasal mucosa and abnormalities in immune phenomena. The endonasal microbiota plays a role in these processes. Germs like Staphylococcus aureus and Pseudomonas aeruginosa were identified as pathogens in CRS in the first studies with bacterial cultures. Thanks to the 16S ribosomal RNA sequencing technique, recent studies have demonstrated a modification in the diversity and abundance of the microbiota in patients with CRS compared to healthy subjects, notably with a modification of the germs of the firmicutes group. . Few studies have studied the modification of the microbiota with the treatment of CRS today. However, local treatments based on nosewashing with physiological saline associated with local corticosteroids and endoscopic treatments lead to an improvement in the symptomatology for patients suffering from CRS. This study will describe the modification of endonasal microbiota in différent conditions, such medical and surgical treatments, that usually improve patients symptomatology.
