Unilateral Hearing Loss Caused By Bilateral Otosclerosis In The Context Of Prior Viral Infection - Case Report, Ryan Tam, Michael Mullinax, Timothy Ehmann, Bryan Scott

Advances in Clinical Medical Research and Healthcare Delivery

This is a case report of a patient who presented with left sided hearing loss. The patient was found to have mixed conductive and sensorineural hearing loss of the left ear and restrictive hearing of the right ear. Subsequent imaging demonstrated evidence of bilateral otosclerosis. Otosclerosis is characterized by progressive pathological bone remodeling in the otic capsule, resulting in hearing loss. Given the disease burden of otosclerosis and the corresponding effects on quality of life, providers must have knowledge of the disease to incorporate it into working differential diagnoses for patients presenting with hearing loss. With increasing recognition of otosclerosis …

Faculty, Staff and Student Publications

A 62-year-old man was referred to our hospital presenting with a sore throat, dyspnea, and cervical swelling. Initial precontrast CT scans revealed a cervical and mediastinal hematoma, along with a hemothorax. Further dynamic contrast-enhanced CT scans indicated contrast media extravasation dorsal to the right thyroid gland lobe, suggesting a rupture of the right inferior thyroid artery or a parathyroid adenoma. Following endotracheal intubation, angiography confirmed extravasation from the right inferior thyroid artery. Transarterial embolization (TAE) was successfully performed using a gelatin sponge. The cervical and mediastinal hematoma were surgically excised, and the right inferior parathyroid gland was simultaneously resected. Pathological …

Radiation Dose In Computed Tomography (Ct), Helen Minnick

Medical Imaging Senior Posters

Computed Tomography (CT) is a critical diagnostic tool that delivers rapid, detailed cross-sectional imaging but remains a major contributor to medical radiation exposure. Increasing use of CT has led to concerns about excessive or low-value exams, including repeat scans that do not often change patient management and may increase long-term cancer risk. Evidence shows that only a small percentage of repeat head CTs reveal clinically significant findings, underscoring the importance of justification and reducing unnecessary imaging. Pediatric patients are particularly vulnerable due to increased tissue radiosensitivity and longer lifespans, making dose optimization essential. National initiatives such as Image Gently and …

A Hidden Source Of Ostomy Bleeding: Meckel Diverticulum, Shiva Morisetty, Ezekiel Kapusiak, Kumar Shah

East Florida Division GME Research Day 2025

Adult Meckel diverticulum can present atypically compared to classic childhood Meckel diverticulum. Given the increased likelihood of concurrent medical conditions in adults, it is often overlooked in the differential for lower gastrointestinal bleeding. We report a 61-year-old male with rectal adenocarcinoma status post low anterior resection and diverting loop ileostomy who presented repeatedly with hematochezia via the ostomy. Prior episodes were managed conservatively. During the index admission, esophagogastroduodenoscopy and ileoscopy did not identify a bleeding source; a clip was placed near the suspected site. Interventional radiology was consulted for mesenteric angiography. Superior mesenteric angiography demonstrated a tortuous aberrant ileal branch …

East Florida Division GME Research Day 2025

Introduction: This case study explores an uncommon triad of encephalitis, ventriculitis, and meningitis complicated by ischemic strokes and seizures in a COVID-19-positive patient. Prior studies suggest that bacterial meningitis and encephalitis can lead to cerebral infarctions due to inflammation and vascular injury.1,2,5 Ventriculitis, in particular, is rarely observed and typically is seen as a severe complication of meningitis, and can be managed with neurosurgical interventions such as CSF shunt placement, ventricular drains, or other intracranial devices.3,4 The simultaneous presentation of all three conditions in a single patient is rare and poses significant challenges from a diagnostic and management standpoint.

Tryptophan Kynurenine Pathway-Based Imaging Agents For Brain Disorders And Oncology-From Bench To Bedside, Erik Stauff, Wenqi Xu, Heidi H. Kecskemethy, Sigrid A. Langhans, Vinay V. R. Kandula, Lauren W. Averill, Xuyi Yue

Jefferson Hospital Staff Papers and Presentations

Tryptophan (Trp)-based radiotracers have excellent potential for imaging many different types of brain pathology because of their involvement with both the serotonergic and kynurenine (KYN) pathways. However, radiotracers specific to the kynurenine metabolism pathway are limited. In addition, historically Trp-based radiopharmaceuticals were synthesized with the short-lived isotope carbon-11. A newer generation of Trp-based imaging agents using the longer half-lived and commercially available isotopes, such as fluorine-18 and iodine-124, are being developed. The newly developed amino acid-based tracers have been demonstrated to have favorable radiochemical and imaging characteristics in pre-clinical studies. However, many barriers still exist in the clinical translation of …
