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.

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 …

Balancing Regeneration And Resistance: Targeting Dclk1 To Mitigate Gastrointestinal Radiation Injury And Oncogenesis, Landon L. Moore, Jerry Jaboin, Milton L. Brown, Courtney W. Houchen

Department of Medicine Faculty Publications

Ionizing radiation (IR) poses a dual challenge in medicine; while essential for cancer therapy, it inflicts collateral damage to normal tissues, particularly the gastrointestinal (GI) tract. High-dose IR triggers acute radiation syndrome (ARS), characterized by crypt stem cell depletion, mucosal barrier disruption, inflammation, and potential progression to fibrosis and secondary malignancy. Emerging evidence identifies the epithelial kinase doublecortin-like kinase 1 (DCLK1)—highly expressed in GI tuft cells and cancer stem-like cells—as a master regulator of post-IR responses. DCLK1 integrates DNA repair (via p53/ATM), and survival signaling (via NF-κB, TGF-β, and MAPK) to promote epithelial regeneration, yet these same mechanisms contribute to …

Sarcoidosis With Isolated Osseous Manifestations Mimicking Metastatic Malignancy, Ahmed Ismail, Ahmed Saleh, Yanis Boumber

Department of Medicine Faculty Publications

Sarcoidosis is an inflammatory disease of unknown etiology that commonly involves multiple organ systems, with the lungs and lymph nodes most frequently affected. Osseous involvement, although recognized, is considered uncommon and often overlooked due to its nonspecific clinical and radiographic features. Patients may be asymptomatic or present with pain, swelling, and functional limitations of the affected limb. Imaging can reveal findings such as bone lesions that mimic malignancy, including lytic or sclerotic changes. Diagnosis relies on histopathological confirmation of non-caseating granulomas. Treatment is directed at symptom relief and preservation of limb function. Here, we present a rare case of isolated …

Ultrasound-Guided Percutaneous Needle Barbotage And Ultrasonic Tenotomy For Rotator Cuff Calcific Tendinopathy, Toru Omodani

Rehabilitation Practice and Science

Rotator cuff calcific tendinopathy (RCCT) is a common source of shoulder pain caused by calcium deposits within the rotator cuff tendons. Ultrasound-guided interventions have emerged as effective, minimally invasive alternatives to surgery for symptomatic cases unresponsive to conservative treatments. This review summarizes two primary techniques: percutaneous needle barbotage and percutaneous ultrasonic tenotomy. In needle barbotage, one or two needles are inserted under ultrasound guidance to inject and aspirate saline, thereby fragmenting and removing the calcific deposit. This method yields rapid pain relief and improved shoulder function, with follow-up imaging often demonstrating near-complete deposit resolution. For particularly hard or recalcitrant deposits, …

Navigating Rarity: A Case Report On Primary Splenic Lymphoma, Santosh Pv Rai, Skand Rastogi, Anshuman Senapati, Jyoti Kini, Salama Yasmeen

Manipal Journal of Medical Sciences

Primary Splenic Lymphoma (PSL) is a rare condition, which complicates its understanding and definition. The rarity of PSL has led to varied definitions: some consider it primary only if splenomegaly is predominant, while others include spleen involvement with hilar lymph nodes. Documentation on PSL is sparse in Indian literature. This case report of a 48-year-old woman, presenting with fever, weight loss, and left hypochondrium pain, and diagnosed with PSL through CECT abdomen and USG-guided biopsy, contributes to better understanding of the condition.

Faculty, Staff and Students Publications

Neurofeedback (NF) is endogenous neuromodulation of circumscribed brain circuitry. While its use of real-time brain activity in a closed-loop system is similar to brain-computer interfaces, instead of controlling an external device like the latter, the goal of NF is to change a targeted brain function. In this special issue on NF, we present current and future methods for extracting and manipulating neural function, how these methods may reveal new insights about brain function, applications, and rarely discussed ethical considerations of guiding and interpreting the brain activity of others. Together, the articles in this issue outline the possibilities of NF use …

Polarimetry Terahertz Imaging Of Human Breast Cancer Surgical Specimens, Nikita Gurjar, Keith Bailey, Magda O. El-Shenawee Dec 2024

Polarimetry Terahertz Imaging Of Human Breast Cancer Surgical Specimens, Nikita Gurjar, Keith Bailey, Magda O. El-Shenawee

Electrical Engineering and Computer Science Faculty Publications and Presentations

Purpose

We investigate terahertz (THz) polarimetry imaging of seven human breast cancer surgical specimens. The goal is to enhance image contrast between adjacent tissue types of cancer, healthy collagen, and fat in excised breast tumors. Based on the biological perception of random growth of cancer and invasion of surrounding healthy tissues in the breast, we hypothesize that cancerous cells interact with the THz electric field in a different manner compared with healthy cells. This difference can be best captured using multiple polarizations instead of single polarization.

Approach

Time domain pulsed signals are experimentally collected from each pixel of the specimen …
