Chronic rhinosinusitis

This study compares a new biodegradable nasal dressing that slowly releases a steroid (mometasone furoate) to a standard steroid-releasing stent, both used after sinus surgery. About 110 adults with chronic sinusitis (with or without nasal polyps) will receive the new dressing in…

This study tests a new treatment for chronic sinusitis, a long-lasting sinus infection that doesn't get better with standard care. Researchers will take healthy bacteria from a donor's sinuses and transfer them into the sinuses of 80 patients, after a special sinus wash. The goal…

This study tests whether a pharmacist-led program can help people reduce their risk of heart disease. Over 1,000 adults with conditions like diabetes, high blood pressure, or obesity are taking part. Pharmacists use a step-by-step guide to assess risk and support lifestyle change…

This early study tests a new approach for people with chronic sinusitis that keeps coming back. A balloon coated with the drug paclitaxel is inflated in the nasal passages to deliver medication directly to the tissue. The goal is to see if it is safe and can reduce symptoms and t…

This study tests an experimental drug called itepekimab in 66 adults with chronic sinusitis who have not improved with standard treatments. Participants receive either the drug or a placebo for 24 weeks. The goal is to see if itepekimab can reduce sinus inflammation and ease symp…

This study tests whether rinsing the nose with a xylitol solution can reduce sinus symptoms in adults with cystic fibrosis. Participants will use both xylitol and standard saline rinses at different times to compare effects. The goal is to see if xylitol, a natural sugar alcohol,…

This pilot study tests whether adding epinephrine to a standard nerve block (pterygopalatine ganglion block) reduces bleeding during functional endoscopic sinus surgery (FESS) in people with chronic rhinosinusitis. Eighty adults undergoing bilateral FESS will receive the nerve bl…

This study follows up to 500 people with acute or chronic inflammatory disorders, such as infections or immune problems, over time. Researchers will monitor participants with standard tests and may screen them for other studies. The goal is to better understand these conditions a…

This study tracks 80 adults with different smell disorders (like total loss, partial loss, or distorted smell) plus healthy volunteers over one year. Researchers use brain scans, smell tests, and questionnaires to see how the brain changes and how smell loss impacts mood and dail…

This study looked at whether having more frequent contact with a clinician (at least once a week) improves satisfaction for people with long-lasting musculoskeletal conditions. Participants were split into two groups: one with standard contact and one with extra check-ins via tex…

This study collects blood, urine, and tissue samples from 330 adults with advanced lung or head and neck cancer to improve precision medicine. Researchers will analyze genetic changes in these samples and grow some tumors in mice to compare DNA. The goal is to refine liquid biops…

This study aimed to find out how often chronic sinusitis occurs in children treated for head and neck cancer, and how it affects their quality of life. Researchers planned to compare these children to those treated for cancer elsewhere in the body using a questionnaire called SNO…

This study tests whether a Norwegian clinic (NSAC) helps people with common mental health issues or muscle pain return to work sooner. 2500 adults are split into three groups: one gets treatment quickly, one waits 10-14 weeks, and one gets a basic check-up. Researchers will track…

This study aims to develop a new way to measure how well the sinuses work in people with chronic sinusitis. About 30 adults with chronic sinusitis and a recent bacterial infection will take the drug ivacaftor. The main goal is to see if a special test can detect changes in sinus …

This study tracks 40 people with nasal polyps and severe asthma who are taking mepolizumab, a drug that reduces inflammation. Researchers collect nose, blood, and sputum samples before treatment and at 3, 6, and 12 months to see how the drug affects symptoms, nose bacteria, and g…

This study investigates why some people develop chronic sinusitis with nasal polyps, focusing on how epigenetic changes and viruses might trigger the disease. Researchers will analyze tissue samples from 60 participants, including patients with active disease, those in remission,…

This study looks back at the medical records of about 4 million people who had physical or occupational therapy for muscle and joint problems. Researchers want to see if different ways of giving therapy lead to different results. No new treatments are tested—the goal is to learn …

This study aimed to see if a mobile monitoring tool could accurately identify surgical site infections (SSIs) in orthopedic surgery patients, compared to the usual manual review. The study was withdrawn before enrolling any participants, so no results are available. It was design…

This study was designed to see how chronic sinusitis affects the tiny hair-like cells (cilia) that help clear mucus from the nose. Researchers planned to use special glowing nano-sticks to measure how well these cells work. However, the study was withdrawn before any participants…

This study looks at the bacteria living in the nose and sinuses of people with chronic sinusitis, allergies, and healthy individuals. By analyzing tissue samples from 285 participants, researchers hope to identify which bacteria are linked to long-term inflammation. The goal is t…

This study looks at the genes of 1,200 adults to find out why some people get chronic sinusitis. Participants must have a CT scan showing either normal sinuses or sinus disease. The goal is to identify genetic variations linked to the condition, which could lead to better underst…

This study is testing a new web-based tool designed to help people with chronic sinusitis make better decisions about their treatment, including whether to have surgery. About 50 patients from USC clinics will use the tool or receive standard information. Researchers will measure…

This study aims to see if a simple, non-invasive breathing test can accurately measure the acidity (pH) in the airways, which is often abnormal in lung diseases. Researchers will compare results from this breath test with standard methods in 150 healthy volunteers and people with…
