Biomedical Porcine Models For The Study Of Surgical Hemostasis, Hindlimb Ischemia, And Pancreatic Cancer, Shruthishree Aravind

Theses & Dissertations

Murine models have dominated the world of biomedical research and comparative medicine since their development in the early 1900s. [1] While they may be suitable models to study proteomics and genomics, they may not serve as effective translational models. [2-4] Murine models do not accurately model the pathophysiology of human disease and are limited by their size, application of medical imaging and intervention, which reduces their overall preclinical predictive value. [2-4]

Porcine models on the other hand, are slowly and steadily bridging the gap between murine models and human patients. [5] Pigs …

Posterior Reversible Encephalopathy Syndrome (Pres), Brittany Fera, Andrew Caravello May 2021

Posterior Reversible Encephalopathy Syndrome (Pres), Brittany Fera, Andrew Caravello

Rowan-Virtua Research Day

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiographic syndrome that describes certain neuroimaging findings in association with clinical symptoms such as headache, seizure, encephalopathy and vision changes. Classically, PRES is associated with poorly controlled hypertension, and patients present with elevated blood pressure in addition to their symptoms. Most importantly, imaging findings and symptoms are typically reversible, and are a separate entity from ischemic or hemorrhagic cerebrovascular accidents or autoimmune causes of similar symptoms, such as multiple sclerosis.


Syncope Or Seizure?, Joseph Heron, Kevin Dwyer May 2021

Syncope Or Seizure?, Joseph Heron, Kevin Dwyer

Rowan-Virtua Research Day

Syncope is a common complaint in the emergency departments, accounting for 1-2% of visits, and can approach admission rates of a staggering 85%. The causes and conditions can be numerous, ranging from benign to life threatening. A good background history can go a long way in determining the etiology of the patient’s syncope. We describe a case of an elderly male who presented with a reported chief complaint of seizures, another syncope-mimic seen in the emergency department. He had a history of CAD, HTN, AAA, and osteoarthritis but no prior history of cardiac arrhythmia, MI, or structural heart disease. The …

Use Of Point Of Care Ultrasound In The Emergency Department For Diagnosis Of Femoral Pseudoaneurysm, Stephen Janssen, Jeffrey Gardecki, Giovanna Finocchio

Rowan-Virtua Research Day

Iatrogenic pseudoaneurysm after puncture or intervention of the femoral artery is a rare complication of arterial surgical intervention occurring in 0.05-0.50% of diagnostic and therapeutic catheterizations and can present weeks after initial presentation. Today we present a 57-year-old gentleman 3 months status post femoral artery stent who presented with swelling to his right groin. Point of care ultrasound was used to diagnose an actively bleeding pseudoaneurysm with hematoma that ultimately led to repeat stenting. This case shows how point of care ultrasound can expedite diagnosis and intervention and is a useful tool for the emergency physician at initial presentation.

Rare Variant Of Porokeratosis: A Case Report, Nardin Awad

Rowan-Virtua Research Day

There are 5 clinically distinct variants of porokeratosis, including classic porokeratosis of Mibelli, disseminated superficial (actinic) porokeratosis, linear porokeratosis, punctate porokeratosis, and porokeratosis palmaris et plantaris disseminate. Porokeratosis ptychotropica (PP) is the sixth, lesser-known variant of the spectrum. PP is characterized by verrucous plaques, often resembling psoriasis plaques, that affect the buttocks, most commonly the gluteal cleft, and can also involve the extremities, most commonly the lower legs and feet. Due to its characteristic verrucous appearance, designations such as verrucous or hyperkeratotic porokeratosis are occasionally used. Besides its predilection for specific locations, PP also has a significant predilection for men …

Spontaneous Conus Medullary Infarction In The Absence Of Cardiovascular Risk Factors, Bavica Gummadi, Jaffer Ahmed, Swarna Rajagopalan

Rowan-Virtua Research Day

Spinal cord infarction (SCI) is rare and most often occurs in individuals with predisposing cardiovascular risk factors and traumatic injuries

As there are no distinct diagnostic criteria for SCI, diagnosis is difficult in patients presenting without predisposing factors and is often mistaken for transverse myelitis.

Delay in early diagnosis contributes to the high case fatality rate of SCI.

This case highlights the importance of including SCI in the differential of a patient with acute paraparesis even in the absence of co-existing risk factors.

Triad Of Acute Pancreatitis Coexisting With Diabetic Ketoacidosis And Very Severe Hypertriglyceridemia Successfully Resolved With Insulin Therapy Alone, Akash Patel, Monica Patel, Yvette Wang

Rowan-Virtua Research Day

Diabetic ketoacidosis (DKA) is known to cause mild elevations in triglyceride levels.

Severe hypertriglyceridemia (HTG) is a well-known cause of acute pancreatitis; however, in unique cases, DKA has been shown to cause severe HTG leading to the development of acute pancreatitis (AP).

HTG causing AP only accounts for 1-4% of cases of AP

From the few cases in literature that have reported this triad of DKA, HTG, and AP, even fewer have shown to be successfully treated with insulin therapy alone with the severe degree of HTG that we discuss.

In our case, we have treated a triad of DKA, …

Septic Arthritis With Concomitant Pseudogout, Ravin Patel, James Schuck, Nicole Zucconi, David Aderholdt

Rowan-Virtua Research Day

Monoarticular joint pain is a common complaint, however it demands a broad differential diagnosis. These differentials include fracture, dislocation, septic arthritis, gout, pseudogout and several others. The diagnosis of septic arthritis requires a high index of suspicion as early diagnosis is a vital part of initial treatment.

We present a case with multifactorial joint pathology contributing to a patient’s presentation, specifically septic joint and pseudogout. The incidence of these entities being present in the same patient, let alone the same joint, is not well documented in the literature.

The presentation of these diseases have a multitude of similarities and differences, …

Case Presentation: Lower Back Pain Or Chronic Acetaminophen Overdose?, Meghan Whitt, Christopher Schwartz, Bhumi Shah

Rowan-Virtua Research Day

Unintentional ingestions can pose a difficult challenge to diagnose in the setting of the Emergency Department. Many may present with vague symptoms that are not consistent with classic overdose prodromes. Many patients do not identify or disclose over the counter medications, such as analgesics, with which acute/chronic ingestion in large quantities can result in life threatening medical emergencies. Their underlying symptoms may also cloud their clinical picture, further complicating workup within the ED.

Theses/Capstones/Creative Projects

Inflammatory Bowel Diseases (IBD) including ulcerative colitis, indeterminate colitis, and Crohn’s disease are increasingly common conditions that places a high physical and financial burden on individuals and global healthcare systems. Though many treatments exist for these conditions, their unpredictable nature and causation make them difficult to manage across the variety of IBD patients. Additionally, many of these treatments come with undesirable side effects or modes of delivery. Therefore, it is worthwhile to explore the use of Short Chain Fatty Acids (SCFAs) such as butyrate whose affects in the human gut include decreased inflammation and decreased risk of colorectal cancer. As …


Imaging Based Prediction Of Pathology In Adult Diffuse Glioma With Applications To Therapy And Prognosis, Evan Gates May 2021

Imaging Based Prediction Of Pathology In Adult Diffuse Glioma With Applications To Therapy And Prognosis, Evan Gates

Dissertations and Theses (Open Access)

The overall aggressiveness of a glioma is measured by histologic and molecular analysis of tissue samples. However, the well-known spatial heterogeneity in gliomas limits the ability for clinicians to use that information to make spatially specific treatment decisions. Magnetic resonance imaging (MRI) visualizes and assesses the tumor. But, the exact degree to which MRI correlates with the actual underlying tissue characteristics is not known.

In this work, we derive quantitative relationships between imaging and underlying pathology. These relations increase the value of MRI by allowing it to be a better surrogate for underlying pathology and they allow evaluation of the …

Investigating Diffusion Tensor Imaging Correlates Of Cognitive Impairment In Idiopathic Normal Pressure Hydrocephalus And Alzheimer's Disease, Omar Hasan, Omar Hasan

Dissertations and Theses (Open Access)

Modest expansion of the human brain cerebrospinal fluid (CSF)-filled ventricles is normal with aging, and because of this, it can be difficult for physicians to accurately diagnose and treat enlarged ventricles (ventriculomegaly), called hydrocephalus1 (fluid or water in the brain) Ventriculomegaly occurs due to an obstruction (such as a blood clot or tumor), or a change in CSF absorption2. Primary hydrocephalus, also called idiopathic normal pressure hydrocephalus (iNPH), is non-obstructive and may be comorbid with other neurodegenerative diseases such as Alzheimer’s disease (AD) or frontotemporal dementia (FTD). Clinically, it can be difficult to tell whether the pathophysiological …
