Active clinical trials for "Nose Diseases"

Nasal patency is an important component of performing exercises because it helps in humidifying, heating and filtering the inhaled air. However, many athletes and exercisers experience difficulty breathing through their nose, which can affect their breathing and performance. Namely, during sports activities and greater physical effort, there is increased air flow, which causes significant dehydration and cooling of the mucous membrane of the upper respiratory system. This dehydration is associated with the release of inflammatory mediators, which can ultimately lead to narrowing of the airways (eg in athletes with asthma). However, in all athletes, regardless of whether they have asthma or not, damage to the airways can occur because during exercise, hyperpnea exposes the respiratory epithelium to increased physical forces and pressure, which leads to the risk of exfoliation of the previously dehydrated epithelial cells of the nose and even their complete separation. Repeated stretching and compression can negatively affect the functionality of the epithelium and, with repeated exposure and damage, lead to structural and functional changes. Rinsing the nose with a hypertonic or isotonic solution of seawater is a potential solution for nasal obstruction because after rinsing, the airflow through the nose improves and symptoms of obstruction are reduced. However, the effects of using nasal lavage solutions along with exercise in elite athletes are not yet known. The potential synergy of exercise and isotonic seawater solution as a nasal spray on airflow and the subjective impression of nasal patency in healthy individuals has not been sufficiently investigated5. Research question What is the effect of an isotonic seawater solution applied as a nasal spray on nasal airflow and the subjective impression of nasal obstruction in healthy athletes? Hypothesis An isotonic seawater solution applied as a nasal spray will improve nasal airflow and the subjective impression of nasal obstruction in healthy athletes.

This study is designed as a masked, two center, randomized, placebo-controlled pilot study to evaluate the safety and efficacy of nasal and oral inhalation of 75 mg aztreonam in subjects with CF and lung infection due to PA. The study will involve two sites: Virginia Commonwealth University Medical Center (VCU) and Eastern Virginia Medical School (EVMS). Potential subjects will be identified in each site's CF clinic.

Investigation of the immediate effect on subjective relief of symptoms by Proponent - Nasal - Spray after a one time administration (following a single dose administration in each nostril) in an open, not randomised, non-blinded single centre observation study on 40 volunteers between 18-75 years of age with an unspecific discomfort in the nose such as enhanced nasal discharge/ secretion (runny nose), congested nose, sneezing, itchy nose or feeling of a dry nose.

The purpose of this study is to evaluate the safety and effectiveness of Hyeonggaeyeongyo-Tang for chronic rhinitis according to pattern identification in Korean medicine.

This prospective study aimed to evaluate the usefulness of squamous cell carcinoma antigen (SCCA) as a clinical marker of sinonasal inverted papilloma (IP). The potential benefit of SCCA in the diagnosis of unilateral nasal pathology and as a marker of hidden recurrence was evaluated as well. Blood samples from patients with sinonasal IP were examined to determine serum SCCA levels before surgery, the day after surgery, and every 6 months during follow-up. Preoperative and postoperative levels of SCCA were compared.

The aim of the project is to define the frequency with which EER is present in patient with chronic rhinosinusitis (CHR). The measurement will be carried out with a 24-hour monitoring of the pH using the Restech system. This modern device is equipped with a narrow antimony probe. The sensor is able to record not only liquid but also aerosol reflux episodes. The second aim is to determine the relation among EER, CHR and asthma bronchiale. We will compare the presence of reflux in three different patient groups (1. CHR without nasal polyposis, without asthma bronchiale or ASA syndrome, 2. CHR with nasal polyposis, without asthma bronchiale or ASA syndrome, 3. CHR with nasal polyposis and asthma bronchiale and/or ASA syndrome). We expect to find a significantly more frequent presence of EER in patients with CHR and asthma bronchiale or ASA syndrome. In case our hypothesis is confirmed, it will be especially these patients(with a difficult to manage nasal polyposis) benefiting from the antireflux therapy.

This study investigate the nasal irrigation with Traditional herbal medicine extract-saline isotonic solution in the treatment of chronic rhinitis and sinusitis. Half of participants will receive Traditional herbal medicine extract-saline isotonic solution nasal irrigation, while the other half will receive saline alone nasal irrigation.

Probiotics are defined as "live micro-organisms that, when administered in adequate amounts, confer a health benefit to the host" (Hill et al, 2014). These microbes are generally applied in the gastrointestinal tract via fermented food products or capsules. In previous research, the investigators isolated bacterial strains with potential probiotic properties for the upper respiratory tract based on in vitro laboratory tests, in vivo mice experiments and genome sequencing. In this study, the investigators want to deliver the Proof-of-Concept that the most promising isolated strain, Lactobacillus casei AMBR2 (LAMBR2) and the well-documented probiotic strain Lactobacillus rhamnosus GG (LGG) also have interesting properties in humans, i.e. that these strains are able to -temporarily- persist in the upper respiratory tract of healthy volunteers and CRS patients after daily nasal application via a nasal spray for 2 weeks. In addition, the investigators aim to explore whether the application of these strains has an impact on the nasopharyngeal microbiome via 16S rRNA amplicon sequencing and dedicated qPCR analysis. Therefore, bacterial DNA from nasal swabs will be isolated via commercially available DNA extraction kits, followed by Illumina MiSeq sequencing in order to identify the bacterial species present in these samples. Furthermore, the concentration of the Lactobacillus and specific pathogens will be monitored via qPCR.

The gold standard surgical treatment for benign nasosinus pathologies is endoscopic surgery. This surgery has experienced considerable growth over the last 30 years. Nevertheless, these techniques can potentially lead to serious complications, with risks of damaging adjacent structures (orbit, optic nerve, meninge or internal carotid artery). Therefore, improving the safety of these procedures is a fundamental objective. Recently, computer-assisted surgery, allowing endonasal navigation, has emerged. It appears to be an asset for the patient, limiting complications and morbidity, and for the surgeon, improving his comfort and reducing his mental workload. The major pitfall of the current technique is the loss of localisation reliability during the intervention due to the registration process and the presence of two screens (to locate the object on the endoscopic image and on the scan) We would like to propose solutions to these limitations using a device based on augmented reality and 3D reconstructions. It would guide the gesture in endonasal endoscopic surgery by displaying high-risk areas and surgical landmarks in a reliable and precise way.

The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
