This study will try to identify and understand the genetic factors that lead to an inner ear malformation called "enlarged vestibular aqueducts", that can be associated with hearing loss. Patients with sensorineural hearing loss with or without inner ear malformations and their parents and siblings may be eligible for this study. Participants and their immediate family members, may undergo some or all of the following tests and procedures: * Medical and family history, including questions about hearing, balance and other ear-related issues, and review of medical records. * Routine physical examination. * Blood draw or buccal swab (brushing inside the cheek to collect cells) - Tissue is collected for DNA analysis to look for changes in genes that may be related to hearing loss. * Hearing tests - The subject listens for tones emitted through a small earphone. * Balance test (VEMP) to see if balance functions of the inner ear are associated with the hearing loss Electrodes will be placed behind your ear and at the base of your neck. From a reclining position, you will be asked to raise your head while clicking sounds are played into your ears. - Ultrasound tests - An inner ear malformation called EVA (enlargement of the vestibular aqueduct) indicates that a genetic disorder called Pendred syndrome may be the cause. Because thyroid abnormalities are also associated with Pendred syndrome, an ultrasound examination of the thyroid gland may be done. * Computed tomography (CT) and magnetic resonance imaging (MRI) scans - These tests show the structure of the inner ear. For CT, the subject lies still for a short time while X-ray images are obtained. For MRI, the patient lies on a stretcher that is moved into a cylindrical machine with a strong magnetic field. The magnetic field and radio waves produce images of the inner ear. The radio waves cause loud thumping noises that can be muffled by the use of earplugs.
NCT03937830
Background: Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world. Most people with advanced HCC survive an average of 6 to 9 months. Researchers are evaluating a combination of treatment drugs to delay the progression of HCC; aiming to help people with HCC live longer. Objective: To study the 6-month progression-free survival in people with advanced HCC treated with bevacizumab, durvalumab, and TACE. Eligibility: Adults ages 18 and older with intermediate or advanced HCC Design: Participants will be screened with a physical exam and medical history. They will have tests to evaluate their hearts as well as blood and urine. A CT and/or MRI scans will be done during the study. If a prior tumor sample is not available; participants may undergo a biopsy. They may undergo an endoscopy of their esophagus and stomach. Participants will get the study drugs in 21-day cycles: Two treatment drugs will be injected into a vein every 3 weeks. Patients will have an interventional treatment procedure done by interventional radiology under sedation; chemotherapy beads will be infused into artery branches in the liver. Participants may have to stay in the hospital for 24 hours for observation, after this procedure. This interventional procedure may be done more than once during the study. Participants may need to repeat some of the screening tests throughout the study. Participants may have to stop taking some of their cancer treatment drugs during the study. Participants will continue on the study until their cancer progresses or until the side effects of the treatment drugs are not tolerable.
