Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar
Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar
Research Symposium
Background: Common cutaneous warts, referred to in medicine as verrucae vulgaris, are proliferative lesions caused by human papillomavirus. These lesions are mostly benign and usually resolve without incident, except in the case of the patient mentioned in this report. Our patient developed a solitary keratoacanthoma, currently accepted as a clinical variant of squamous cell carcinoma, as a result of several risk factors and traumatic exposure. The current literature does not have an established association of HPV with solitary keratoacanthomas. This case report explores the presentation and pathogenesis of solitary keratoacanthomas within the setting of HPV.
Case Presentation: 48-year-old Caucasian female …

Case Of Rosai Dorfman Disease In A Patient With Newly Diagnosed Hodgkin Lymphoma, Liza Salloum, Jennifer Rojas Huen, Ricardo Serna, Alisha Valdez
Research Symposium
Background: Rosai Dorfman Disease (RDD, also known as sinus histiocytosis with massive lymphadenopathy) is a rare non-Langerhans cell histiocytosis, classified into nodal (classic) and extranodal disease. Most patients present with non-tender cervical lymphadenopathy, although other sites including the inguinal and axillary regions have been reported. Extranodal disease (~43% of cases) can involve any organ system. RDD is more common in children, but cases have been reported in patients in their 70s. The prognosis of nodal RDD can correlate with the number of nodal groups involved. Many cases can be managed only with observation, although surgery, chemotherapy, corticosteroids, and immunomodulators have …

Foci Of Idc In Phyllodes Tumors: Should We Be Worried?: A Systematic Review Of The Literature, Kathryn Eckert, Victoria Tiedemann, Linda Szczurek
Rowan-Virtua Research Day
Phyllodes tumors are rare, fast growing fibroepithelial tumors of the breast that account for less than 1% of all breast tumors globally. They were first characterized by Johannes Muller in 1838 and most often present in the 5th decade of life. Phyllodes tumors are histologically composed of a stromal component and an epithelial component. The stromal component has a widely accepted malignant potential in up to 30% of cases. Grading of the stromal malignant potential of phyllodes tumors has been defined by the World Health Organization (WHO) as benign, borderline, or malignant based on the presence and degree of stromal …

Design And Development Of Software With A Graphical User Interface To Display And Convert Multiple Microscopic Histology Images, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy
UNO Student Research and Creative Activity Fair
Histological images are widely used to assess the microscopic anatomy of biological tissues. Recent advancements in image analysis allow the identification of structural features on histological sections that can help advance medical device development, brain and cancer research, drug discovery, vascular mechanobiology, and many other fields. Histological slide scanners create images in SVS and TIFF formats that were designed to archive image blocks and high-resolution textual information. Because these formats were primarily intended for storage, they are often not compatible with conventional image analysis software and require conversion before they can be used in research. We have developed a user-friendly …

Covid-19 Myocarditis: Quantitative Analysis Of The Inflammatory Infiltrateand A Proposed Mechanism, Lacey Rogers, Sharon Fox, Richard Vander Heide
Medical Student Research Poster Symposium
COVID-19 has a significant effect upon the cardiovascular system. While a number of different cardiovascular histopathologies have been described at post-mortem examination, the incidence of typical viral myocarditis in COVID-19 positive patients appears very low. In this study, we further characterize and quantify the inflammatory cell infiltrate in a COVID-19 study cohort and compare the findings to both an age and disease matched control cohort of patients diagnosed with typical inflammatory myocarditis. All study and control cohorts had 1 or more of the comorbities most commonly associated with severe disease (hypertension, type II diabetes, obesity, or known cardiovascular disease). The …

Case Report: Post-Partum Headache, Alaleh Ebrahimi
Case Report: Post-Partum Headache, Alaleh Ebrahimi
Rowan-Virtua Research Day
Cerebral venous sinus thromboses are rare and occur in 5 people/1,000,000, more commonly in women that are pregnant at about 202/100,000 deliveries with an 11.63% mortality rate. It is believed that pregnancy being a hypercoagulable state is one of the main reasons that it is more common in pregnant and post-partum women. Common symptoms include sudden onset headache, blurry vision, focal neuro deficits, seizures and altered mental status.

Tb Incidence In Us And Puerto-Rico From 1993 To 2017, Bowranigan Tharmalingam, Amber Todd
Medical Student Research Symposium Abstracts and Posters
The objective of this project is to test for possible correlation between the trend of Tuberculosis incidence rate in the US and the Tuberculosis incidence rate in PuertoRico from 1993 to 2017. Data from CDC Wonder-Online Tuberculosis InformationSystem and Pearson Correlation test were used to investigate the relationship. Analysis shows a positive association and a significant correlation between TB incidence rate between both region during the 26-year timeframe. This result has the potential for in-depth future research to identify the common variables and causes for the positive correlation.
Is Microscopic Colitis Associated With Increased Risk For Other Gastrointestinal Diseases?, Tanner Graves, Paul Koles
Is Microscopic Colitis Associated With Increased Risk For Other Gastrointestinal Diseases?, Tanner Graves, Paul Koles
Medical Student Research Symposium Abstracts and Posters
Microscopic colitis is clinically suspected in patients with recurrent watery diarrhea and the absence of gross pathologic changes in the colon by endoscopic examination. The diagnosis is established only by microscopic evaluation of colonic biopsies. Microscopic colitis is currently classified into three subgroups: collagenous colitis (CC), lymphocytic colitis (LC), and combined CC and LC. The incidence rates are 4.14 per 100,000 person-years and 4.85 per 100,000 person-years for CC and LC, respectfully.
Diagnosis is typically made without measuring the exact thickness of the subepithelial collagen band or by counting the number of lymphocytes in the epithelium. There is little research …
Phylogenetic Estimates Of Hiv-1 Gp120 Indel Rates Across The Group M Subtypes, John Palmer, Art Poon
Phylogenetic Estimates Of Hiv-1 Gp120 Indel Rates Across The Group M Subtypes, John Palmer, Art Poon
Western Research Forum
Insertions and deletions (indels) in the HIV-1 envelope glycoprotein gp120 play a significant role in the evolution of HIV pathogenesis and transmission fitness. While substitution rates in HIV-1 are well characterized by phylogenetic models, there is a lack of quantitative measures of indel rates in HIV-1. Here we use a dated-tip phylogenetic analysis of gp120 sequences to estimate indel rates for 7 subtypes and CRFs of HIV-1 group M.
We obtained and processed 26,359 HIV-1 gp120 sequences from the Los Alamos National Laboratory HIV Sequence database. After filtering these sequences, we extracted the conserved and variable regions from the remaining …

Onyx Use In Extracranial Pathologies - A Retrospective Case Review, Faezeh Razjouyan, Rishi Sood, Alex Cho, Anthony Venbrux, Shawn Sarin
GW Research Days 2016 - 2020
Purpose:
Onyx is an embolic agent currently FDA approved for neurointerventional procedures such as in the treatment of aneurysms and arteriovenous malformations. Despite its limited indications, the agent's off-label use in the treatment of extracranial pathologies continues to increase. To date, there has not been a single-center study demonstrating a large number of cases demonstrating safe and effective peripheral embolization with Onyx.
Materials:
We performed a retrospective review of all cases that used Onyx between October 2010 and July 2016 at a single tertiary care academic university urban hospital. Institutional review board approval was appropriately obtained. Initial case selection was …

Head Injury Risk And Car Seat Use For Children In Collisions, Peyton A. Schroeder, M.J. Skhurm, D. Fraser, K. Mcclafferty
Western Research Forum
Background: Motor vehicle collisions (MVCs) are the leading cause of death for people under the age of 17 years. Almost 80% of rear seat motor vehicle passengers are children. Previous studies have shown that a large fraction of injuries to children in MVCs involved the head and chest. In this study, the hypothesis that children under the age of eight using a forward-facing child restraint system (FFCRS) will have more severe head injuries than children using any other type of restraints in an MVC was tested.
Methods: Several datasets obtained from Transport Canada and Level 1 Pediatric Trauma Centre emergency …

Performance Of Non-Invasive Tests To Predict Significant Liver Fibrosis In Patients With Morbid Obesity, Ahmed Bakhshwin, Patricia Latham
Performance Of Non-Invasive Tests To Predict Significant Liver Fibrosis In Patients With Morbid Obesity, Ahmed Bakhshwin, Patricia Latham
GW Research Days 2016 - 2020
Non-Alcoholic Fatty Liver Disease (NAFLD) affects more than 90% of patients with morbid obesity (MO) and approximately 30% have significant liver fibrosis and/or cirrhosis. Liver biopsy is the gold standard for diagnosis of significant liver fibrosis and cirrhosis; however, several non-invasive tests have been suggested to predict the presence or absence of significant liver fibrosis and to avoid liver biopsy in these patients. The aim of this study was to determine the ability of these tests to predict significant liver fibrosis, specifically in patients with MO.
Methods:
Liver biopsies from patients with MO undergoing gastric bypass surgery were studied in …
