Detection Of Progression Or Regression Of Breast Cancer By Circulating Tumor Dna (Ctdna), Ujjwal Karki, Bipin Ghimire, Emma Herrman, Siddhartha Yadav, Mohammad Muhsin Chisti

Conference Presentation Abstracts

Circulating tumor DNA (ctDNA) are short DNA sequences shed by tumor cells into the systemic circulation. Studies have shown potential utility of the test to predict relapse or recurrence following treatment in solid tumors, but sensitivity and specificity have varied widely, ranging from 19-100% and 80-100% respectively, in breast cancer specifically. Moreover, literature describing the utility of monitoring dynamic changes in ctDNA trends is limited. We aim to evaluate the correlation between ctDNA test, both single test as well as dynamic trends in value over time, with imaging findings.

Responsive Neurostimulation (Rns) Of The Centromedian Nucleus Of The Thalamus For The Treatment Of Drug Resistant Idiopathic Generalized Epilepsy, Angelique Manasseh, Hannah Guider, Brooklynn Bondy, Ayman Haykal, Nour Baki, Ashleigh Terrell, Michael Staudt, Christopher Parres, Andrew Zillgitt

Conference Presentation Abstracts

Rationale: Idiopathic generalized epilepsy (IGE) accounts for approximately one-third of all epilepsies. The majority of people with IGE achieve seizure-freedom from treatment with anti-seizure medications (ASM). However, up to 25% of people with IGE continue to experience seizures despite adequate ASM trials. In patients with drug resistant IGE, neuromodulation with responsive neurostimulation (RNS) in the bilateral centromedian nucleus (CMN) of the thalamus may be an effective treatment option. Methods: Five patients with drug resistant IGE were evaluated through the Beaumont Adult Comprehensive Epilepsy Center and underwent an epilepsy presurgical evaluation including video-EEG monitoring in the epilepsy monitoring unit, brain MRI, …

Prevalence Of Allergic Fungal Sinusitis In Nonspecific Allergic Sinusitis, P L. Zhang, H D. Kanaan

Conference Presentation Abstracts

Background: Increased eosinophils in sinus contents are regarded as nonspecific allergic sinusitis. However there are only a few studies addressing the rate of fungal infection associated allergic fungal sinusitis in non-specific allergic sinusitis. This study was to identify the prevalence of allergic fungal sinusitis in the sinus content specimens with increased eosinophils. Methods: A computer search for allergic sinusitis was done over a 4 year period of time. And allergic fungal sinusitis was individually identified within listed allergic sinusitis cases. Each individual case of allergic fungal sinusitis was reviewed in correlation with sinus culture findings and the prevalence of allergic …

Increased Eosinophils In The Muscularis Propria Of Appendix May Indicate Early Symptomatic Appendicitis, Ping L. Zhang, Zhenhong Qu

Conference Presentation Abstracts

Background: The presence of neutrophils in muscularis propria is known to best correlate with clinical symptoms of acute appendicitis. Eosinophils present in the muscularis propria were noted in cases of acute appendicitis in 2000 (Carr, NJ. Annal of Diagnostic Pathology 2000;4:46–58), but the significance of their presence there has been unclear. The goal of this study was to investigate whether increased eosinophils in muscularis propria could be correlated with early symptoms of patients with clinical diagnosis of symptomatic appendicitis.

Methods: Seventeen patients with clinical diagnosis of acute appendicitis were identified as having acute symptomatology, but the resection specimens displayed a …

Conference Presentation Abstracts

Introduction

Non-alcoholic fatty liver disease (NAFLD) is one of the leading causes of chronic liver diseases. NAFLD spectrum begins from simple steatosis to non-alcoholic steatohepatitis (NASH), progressive fibrosis, cirrhosis, and even hepatocellular carcinoma. Although most NAFLD patients are overweight and obese, 30% are lean. We analyzed lean and non-lean NAFLD patients’ liver biopsies for cytokeratin 8/18 immunohistochemical staining differences.

Aims & Methods

Thirty biopsy-proven NAFLD patients (15 patients with BMI ≤ 25 kg/m2, 15 patients with BMI > 25 kg/m2) were included in the study. Demographic, biochemical, and histologic features of the patients were recorded. Biopsy specimens from our archive were …

Bet Protein Complexes With Ets1 And Mediates The Senescence-Associated Secretory And Apoptotic Resistant Phenotypes Of Senescent Cholangiocytes, Jeong-Han Kang, Patrick Splinter, Christy Trussoni, Nicholas E. Pirius, Maria Eugenia Guicciardi, Anuradha Krishnan, Nazli Begum Ozturk, Gregory J. Gores, Nicholas F. Larusso, Steven P. O'Hara

Conference Presentation Abstracts

Background: We reported that cholangiocyte senescence is a pathogenic feature of Primary Sclerosing Cholangitis (PSC) and is regulated by the transcription factor, ETS1. We also showed that Histone 3 Lysine 27 is acetylated at senescence-associated loci. The bromodomain and extra-terminal domain (BET) proteins are epigenetic readers that bind acetylated histones, recruit transcription factors, and drive gene expression. Thus, we tested the hypothesis that BET proteins interact with ETS1 to drive gene expression and promote cholangiocyte senescence. Methods: We performed immunofluorescence to assess cholangiocyte expression of two BET proteins, BRD2 and BRD4, in tissue from PSC patients and PSC mouse models …
