Deletion Of Chemokine Receptor 6 Augments Ductular Reaction And Fibrosis In A Mouse Model Of Cholestatic Liver Injury, Nazli Begum Ozturk, Kaiyel Cutshaw, Anuradha Krishnan, Gregory J. Gores

Conference Presentation Abstracts

Background: The chemokine CCL20 is expressed by activated cholangiocytes implicating its’ receptor, CC-chemokine receptor 6 (CCR6) in immune cell trafficking to the liver during cholestatic liver injury. In particular, the innate immune cells macrophages and neutrophils have been identified in cholestatic liver injury. Therefore, our aim was to investigate the effect of CCR6 deletion on a mouse model of 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet-induced cholestatic liver injury. Methods: Age and gender matched WT and Ccr6-/- mice were placed on an DDC or a control diet for 21 days. Serum biochemistry, liver injury and the ductular reaction (DR) were examined by standard …

The Diagnostic Role Of Cytokeratin 8/18 Immunohistochemical Marker For Lean Non-Alcoholic Fatty Liver Disease, P Telli, M Buyuk, Nazli Begum Ozturk, Z Istemihan, K Nuriyev, A Atasoy, B Cavus, A Cifcibasi Ormeci, U Akyuz, K Demir

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 …

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 …

Paneth Cell-Like Granules In Clear Cell Renal Cell Carcinomas Are Cd68 And Lysozyme Positive Lysosomes, P L. Zhang

Conference Presentation Abstracts

Background:Paneth cells with features ofneuroendocrine differentiation can be seen inmultiple organs and various tumours. Paneth cell-likegranules in clear cell renal cell carcinomas (RCC)have previously been reported, but are found noexpression of neuroendocrine markers. Given thatclear cell RCC are rich in phagocytic factors, wehypothesized that the Paneth cell-like granules inclear cell RCC were associated with lysosomes.Methods:In this study, 72 different renal tumoursincluded 42 clear cell RCC, 16 papillary RCC, 5 clearcell papillary RCC, 6 chromophobe RCC, 2 urothelialcarcinomas and one unclassified RCC. All tumourswere evaluated for the Paneth cell-like granules onhaematoxylin & eosin stained sections. In addition,PAS-D staining, immunohistochemical stains andelectron …

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 …

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 …

Irreversible Electroporation For Recurrent Pelvic Metastases: Case Series And Literature Review., Duncan A. Stevens, Jeffrey H. Savin, Brett J. Friedman, Michael A. Savin

Conference Presentation Abstracts

Purpose: Irreversible electroporation (IRE) is a nonthermal ablative technique that has potential safety advantages over thermal ablation in the treatment of tumors near critical structures. It creates an electrical field which forms permanent nanopores in the membranes of cells and triggers apoptosis. This case series reviews three patients with pelvic metastases from colorectal cancer treated with IRE.

Material and Methods: Two patients had rectal cancer and one sigmoid colon cancer. The mean age was 55 years and there were two males and one female. Thermal ablation was contraindicated due to proximity to ureter, bladder, bowel, and/or sciatic or lumbosacral nerves. …

Protecting Wellness And Boundaries While Navigating Leaves Of Absences: Case Studies For Approaching From An Ethical And Behavioral Health Lens, Jennifer Kowalkowski, Sawsan Edriss, Stephen Warnick

Website/Multimedia Contributions

The new ACGME guidelines for paid 6-week family and medical leave are a big step forward in helping our residents maintain their health and well-being. Previously noted for having one of the strictest leave allowances among medical specialties, family medicine programs may see future increases in leave requests due to policy changes extending allowable leave times and increased stress from both the Covid-19 pandemic and current mental health crisis facing our nation. Leaves that involve physical or mental health crises are certainly very difficult for the resident on leave but can significantly impact co-residents and program faculty as well. Our …
