The aim of this research study is to evaluate the effectiveness and safety of a combination of immunotherapy, using a drug called toripalimab, with chemotherapy drugs, Carboplatin and Docetaxel, as a possible treatment before surgery for sinonasal cancers. The names of the study drugs used in this research study are: * Toripalimab (a type of monoclonal antibody) * Carboplatin (a type of antineoplastic agent) * Docetaxel (a type of antineoplastic agent) * Cisplatin (a type of antineoplastic agent)
To learn about the symptoms and changes our patients experience while receiving treatment for sinonasal or nasopharyngeal cancer
This is a single arm phase II study that will evaluate the combination of pembrolizumab, docetaxel, and cisplatin or carboplatin (PDC) as single treatment modality in patients with stage II-IVb (T2-4, any N, M0) squamous cell carcinoma of the nasal cavity/paranasal sinuses (PNS SCC).
The purpose of this study is to assess the safety and effectiveness of the Peregrine endoscope in patients in the office setting in terms of access into and visualization of the paranasal sinus anatomy, image quality, patient tolerability and clinical utility. Up to 30 participants who have had prior endoscopic sinus surgery (ESS) and are scheduled for nasal endoscopy in the office as part of a routine post-operative office visit or due to recurrence of symptoms, will be evaluated with the Peregrine Endoscope as well as a standard endoscope. This study aims to: * compare visualization success rates of the paranasal sinus anatomy by Peregrine and by a standard endoscope used in the office setting. * examine device related adverse events. * assess the adequacy of the image quality of Peregrine for endoscopy procedures in the office. * evaluate patient tolerability and pain
This randomized phase II trial studies how well chemotherapy before surgery and radiation therapy works compared to surgery and radiation therapy alone in treating patients with nasal and paranasal sinus cancer that can be removed by surgery. Drugs used in chemotherapy, such as docetaxel, cisplatin, and carboplatin work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy before surgery and radiation therapy may make the tumor smaller and reduce the amount of normal tissue that needs to be removed and treated with radiation.
This study is being done to test a new treatment plan for large tumors in the sinus or nasal cavity that will include endoscopic surgery plus chemotherapy and proton-beam radiation therapy.
This randomized phase I trial studies how well olfactory training works in improving sense of smell after radiation therapy in patients with paranasal sinus or nasopharyngeal cancer. Olfactory training may improve smell function after radiation therapy in patients with paranasal sinus or nasopharyngeal cancer.
Deliberate hypotension, reverse Trendelenburg position, and hyperventilation are techniques utilized during functional endoscopic sinus surgery to attempt to reduce surgical bleeding. These methods reduce blood flow to the head and neck area and assist in reducing bleeding during surgery but they may predispose patients to cerebral ischemia. Large scale studies necessary to conduct adequate statistical analysis regarding the effect of cerebral oximetry on otolaryngology surgery has not been extensively studied. This study seek to address the question of whether cerebral oximetry in the FESS population can help evaluate major and minor post operative morbidity, as well as the quality of recovery from surgery. Cerebral oximeters are small, noninvasive stickers applied to the forehead of participants and give the examiners data regarding the level of oxygen saturation around the brain during the course of surgery. During the course of such procedures, where blood flow to the head and neck area is intentionally decreased to assist in reducing bleeding during surgery, the levels of oxygen saturation around the brain may pose as a predictor or major and minor post operative morbidity, as well as the quality of recovery from surgery. Outcome measures will include major post operative complications, such as neurological and cardiac complications, and minor post operative morbidity, such as length of post anesthesia care unit (PACU) length of stay, nausea, and vomiting. Quality of recovery will also be assessed using a survey conducted in the PACU and again at the first post operative visit approximately one week after surgery.
The purpose of this study is to determine if a trial of directed high-dose nasal steroids improves residual smell loss in patients with chronic rhinosinusitis following sinus surgery. Other outcomes of this study include: identifying the differences in sinus airflow between patients who improve following nasal steroid treatment and those who do not, and to see if, in patients who improve following surgery, the improvement remains throughout follow-up.
The purpose of this study is to collect information from a questionnaire and medical records to see what effects proton radiation has on cancer and collect and analyze morbidity outcomes: incidence of Xerostomia (dry mouth) and tumor control.
This phase II trial studies how well docetaxel, cisplatin and fluorouracil work in treating patients with previously untreated stage II-IV nasal cavity and/or paranasal sinus cancer. Drugs used in chemotherapy, such as docetaxel, cisplatin and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
This research project designed to diagnose sinusitis using a simple and low-cost optical tool. Healthy sinuses are typically filled with air, and show up as bright spots on the camera. Infected sinuses are filled with fluid and show up dark spots on the camera. Images of infected sinuses could be used to diagnose sinusitis, or to check if surgical treatments on the sinuses have been successful.
Uncontrolled hypertension (HTN) is growing in incidence globally creating a critical need for alternative therapeutic strategies. Directly stimulating the carotid sinus nerve (CSN) is known to potentially reduce blood pressure (BP) but its clinical efficacy has not been consistently demonstrated with existing electrode technologies in humans. We investigated the effect of acute direct CSN stimulation on BP and HR in anesthetized humans using an application-specific multi-contact electrode.
Investigators performing this research want to look at the use of a special imaging process during a specific throat surgery. Using this imaging may help to lower a common complication that called a pharyngocutaneous fistula (PCF). A PCF is a leak in the tube in the throat that helps with breathing and digesting food. The imaging is called the SPY Fluorescence System. This system can identify tissue that is not receiving enough blood. The SPY Fluorescence System uses a special dye, called Indocyanine green (ICG) to better see the tissues that are not receiving enough blood. When tissue does not receive enough blood, it can lead to infection. Infection of tissue in this area of the throat can lead to PCF. The imaging takes about 1 minute and is performed in the operating room during surgery. For this study, the investigators (who are also surgeons) will decide to remove tissue that is identified by the SPY Fluorescence System to have decreased blood flow. They will then continue with the rest of the surgery as usual. The investigators will monitor participants as they recover from surgery to identify any complications that may occur. For this research they are interested in complications during the first month after surgery since this is when PCF usually happens. Investigators will use information that has been documented in the medical records of participants as well as during in-person physical examinations during inpatient recovery and outpatient clinical visits.
The Velocity Percutaneous Arterio-Venous System is a minimally invasive method of creating hemodialysis vascular access. The study aims to understand clinical efficacy and initial clinical safety data of the device.
Study to assess the feasibility of dialysis clinic staff to perform upper limb mapping ultrasound scans using the Vexev Ultrasound Imaging System.
The average success rate for healing and remission of complex perianal fistulas, idiopathic or Crohn's-related, is approximately 50%. These abnormal connections between the rectum and the outside skin remain a major clinical challenge in need of new treatments aimed at tissue repair. Platelet-derived growth factor drives wound healing and tissue regeneration, and manufactured PDGF is currently used to heal diabetic foot ulcers and regenerate bone in periodontal and orthopedic patients. Manufactured recombinant human PDGF has the potential to improve the success rate for complete healing of complex perianal fistulas, reduce the recurrence rate due to reopening of the fistula tract, and avoid complications associated with routine surgical interventions.
VasQ is an external support implant for arteriovenous fistulas created for dialysis access. This is a postmarket surveillance, prospective, multi-center, randomized, controlled, open label trial enrolling 300 patients randomized into two study arms: * Treatment arm: End to side fistula supported with VasQ * Control: Standard of care end to side fistula
The goal of this clinical study is to learn if cone beam computed tomography (CBCT) or 3-dimensional x-ray can help to let the investigator know if dental implant placement can be done after performing closed sinus surgery. The study will look at the structure of your gum where the implant will be placed after performing the surgery using 3-D x-ray and compare that to how the structure of your gum looks 6 months later. The 3-D imaging will happen after standard of care surgery to prepare your gum for an implant and then 6 months later to verify that the site is ready for the implant.
This a single-center, retrospective, observational study of patients that undergo coronary sinus(CS) lead revision, comparing epicardial lead placement to coronary sinus pacing(CSP) in those that had lead failure.
A closed sinus augmentation is performed for dental implant placement.
The goal of this randomized clinical trial is to test the topical drug clascoterone in patients with pilonidal disease, which is a common, benign skin condition of the gluteal cleft. The main questions it aims to answer are: * Does clascoterone improve the severity of pilonidal disease as scored by a physician? * Does clascoterone improve patient symptoms due to pilonidal disease? * Does clascoterone improve the inflammation seen under the microscope in pilonidal disease removed at surgery Participants will apply clascoterone or a placebo cream to the diseased area for 3 months. They will be assessed every 4 weeks for disease severity assessed by a physician viewing patient photos and a symptom-based survey. Researchers will compare participants who received clascoterone treatment to those who received placebo.

This is a prospective, observational study examining the impact of highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulators on chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) in young children with cystic fibrosis (YCwCF). This study involves two groups: children 2-8 years old, inclusive at initial visit, receiving highly effective modulator therapy (HEMT), and a control group of children 2-8 years old, inclusive at initial visit, not receiving HEMT. Outcomes will include sinus magnetic resonance imaging (MRI) scans, olfactory tests, and quality of life surveys obtained over a two-year period.
This is a prospective, multi-center, two-arm, randomized trial to quantify the performance of the EchoMark®/EchoSure® System for AVF diagnostic ultrasound when used under a protocol of biweekly use for assessing fistula maturation and reducing time to Clinical Maturation.
The purpose of this clinical trial is to assess if the addition of DFDBA fibers to DBBM results in greater vital bone formation than the addition of DFDBA particles to DBBM. The study team will examine the effects of the addition of DFDBA fibers to DBBM on vital bone formation. Specifically, we will assess histologically the percent vital bone formation with each of the groups during implant placement, six months after the sinus augmentation procedure. We will also evaluate the radiographic volume achieved with both groups of materials.
