Warren B. Davis And The Birth Of Plastic Surgery In Philadelphia: A Historical Vignette, Sarah F. Wagoner, Charles J. Yeo, Renee M. Tholey, James W. Fox, Steven E. Copit

Department of Surgery Faculty Papers

The field of plastic surgery, formally organized in 1931 with the founding of the American Society of Plastic and Reconstructive Surgery, was shaped in many ways by a small practice of Philadelphia physicians. At the center of the practice was Warren B. Davis, a Philadelphia otolaryngologist and plastics pioneer whose innovations in cleft palate surgery would lead to significant improvements in functional and cosmetic outcomes in his time. In addition to his own innovations, Davis was responsible for the training of John Reese, the inventor of the Reese dermatome that changed the face of burn medicine during World War II. …

Pyrvinium Pamoate: Past, Present, And Future As An Anti-Cancer Drug, Christopher W Schultz, Avinoam Nevler

Department of Surgery Faculty Papers

Pyrvinium, a lipophilic cation belonging to the cyanine dye family, has been used in the clinic as a safe and effective anthelminthic for over 70 years. Its structure, similar to some polyaminopyrimidines and mitochondrial-targeting peptoids, has been linked with mitochondrial localization and targeting. Over the past two decades, increasing evidence has emerged showing pyrvinium to be a strong anti-cancer molecule in various human cancers in vitro and in vivo. This efficacy against cancers has been attributed to diverse mechanisms of action, with the weight of evidence supporting the inhibition of mitochondrial function, the WNT pathway, and cancer stem cell renewal. …

Biomarkers In The Development Of Individualized Treatment Regimens For Colorectal Cancer, Madison Crutcher, Scott A Waldman

Department of Surgery Faculty Papers

Introduction: Colorectal cancer (CRC) is the third most common and second most deadly malignancy in the world with an estimated 1. 9 million cases and 0.9 million deaths in 2020. The 5-year overall survival for stage I disease is 92% compared to a dismal 11% in stage IV disease. At initial presentation, up to 35% of patients have metastatic colorectal cancer (mCRC), and 20-50% of stage II and III patients eventually progress to mCRC. These statistics imply both that there is a proportion of early stage patients who are not receiving adequate treatment and that we are not adequately treating …

Failure Factors For Carpal Tunnel Syndrome Surgical Treatment: When And How To Perform A Revision Carpal Tunnel Decompression Surgery, Carlos Henrique Fernandes, João Baptista Gomes Santos, Francisco Schwartz-Fernandes, A. Lee Ostermann, Flávio Faloppa

Department of Surgery Faculty Papers

Despite being a procedure widely used all over the world with high rates of symptom remission, surgical treatment of carpal tunnel syndrome may present unsatisfactory outcomes. Such outcomes may be manifested clinically by non-remission of symptoms, remission of symptoms with recurrence a time after surgery or appearance of different symptoms after surgery. Different factors are related to this unsuccessful surgical treatment of carpal tunnel syndrome. Prevention can be achieved through a thorough preoperative clinical evaluation of the patient. As such, the surgeon will be able to make differential or concomitant diagnoses, as well as determine factors related to patient dissatisfaction. …

The Role And Outcomes Of Thoracodistal Bypass, Andrea Mcsweeny, Anthony Feghali, Tuong Nguyen, Michael Nooromid, Dawn Salvatore, Paul Dimuzio, Babak Abai

Department of Surgery Faculty Papers

Objectives

Endovascular procedures for lower extremity revascularization are becoming more commonplace due to low morbidity, mortality, and shorter length of stay. The role of open bypass must be reconsidered. Aortobifemoral bypass is the gold standard for extensive aortoiliac occlusive disease (AIOD); however, thoracodistal bypass holds a niche position. We investigate indications and outcomes of thoracodistal bypass.

Methods

Medical records of five patients who underwent thoracodistal bypass at Thomas Jefferson University Hospital (TJUH) between 2012 and 2019 were reviewed. Contemporary and historical literature was reviewed.

Results

Indications included calcified paravisceral pathology, previous failed or infected bypass grafts, and prior abdominal operations. …

Department of Surgery Faculty Papers

INTRODUCTION: Gastric cancer (GC) is the third leading cause of cancer-related death worldwide. Surgical resection is the gold standard of treatment. In the United States, race and socioeconomic status are associated with the diagnosis of GC; however, no studies have examined these as independent risk factors for surgical outcomes. Our study sought to investigate socioeconomic factors and GC surgical outcomes using a national cancer registry.

METHODS: GC patients between 2004 and 2016 were identified using the National Cancer Database. Univariate and multivariate logistic regression was used to analyze associations between socioeconomic factors and 30-d mortality, 90-d mortality, and unplanned readmission …

Popliteal Artery Entrapment Syndrome Treated By A Posterior Approach In A 15-Year-Old Athlete, Lili Sadri, Robert L Myers, Casey Paterson, Quyngdiem Lam, Danielle M Pineda

Department of Surgery Faculty Papers

Popliteal artery entrapment syndrome is a rare source of claudication in young people. We present the case of a 15-year-old male athlete who presented with intermittent numbness of his right foot with exertion. Imaging revealed classic compression from a right type III popliteal artery entrapment. The left popliteal artery was chronically occluded with a large collateral vessel. He underwent release of the accessory bands of the gastrocnemius muscle with significant arteriolysis on the right side via a posterior approach. Chronic popliteal artery entrapment can be treated from a posterior approach, resulting in arterial occlusion and will be asymptomatic if well …

Coil Embolization Of Ruptured Distal Renal Artery Pseudoaneurysm With Gross Hematuria And Hemorrhagic Shock, Andrea Mcsweeney, Anand Tarpara, Dawn Salvatore, Paul J Dimuzio, Michael Nooromid, Babak Abai

Department of Surgery Faculty Papers

Renal artery pseudoaneurysms have been infrequently reported in the literature. In the present report, we have described a case of a ruptured renal artery pseudoaneurysm requiring coil embolization. A 49-year-old man had presented to our institution with a hypertensive emergency. Computed tomography revealed a 3.4-cm right renal artery pseudoaneurysm. Nonemergent coil embolization was planned for the following day. However, he became hypotensive, exsanguinating frank blood from the urethra. An arteriogram showed extravasation of contrast into the pseudoaneurysm sac, renal pelvis, and ureter, consistent with intrarenal pseudoaneurysm rupture. We have demonstrated coil embolization as a method of repairing a ruptured renal …

Department of Surgery Faculty Papers

INTRODUCTION: Achieving satisfactory post-operative pain control for common elective general surgical procedures, while minimizing opioid utilization, remains challenging. Utilizing pre-operative educational strategies, as well as multimodal analgesia, we sought to reduce the post-operative opioid use in elective general surgery cases.

METHODS: Between November 2019 and July 2021, patients undergoing elective inguinal hernia repair or cholecystectomy were enrolled in the study. Patients were divided into three cohorts: Control, opioid sparing (OS), or zero-opioid (ZO). Control patients did not have any intervention; OS patients had an opioid reduction intervention protocol applied (patient education and perioperative multimodal analgesia) and were provided an opioid …

Pnc-27, A Chimeric P53-Penetratin Peptide Binds To Hdm-2 In A P53 Peptide-Like Structure, Induces Selective Membrane-Pore Formation And Leads To Cancer Cell Lysis, Ehsan Sarafraz-Yazdi, Stephen Mumin, Diana Cheung, Daniel Fridman, Brian Lin, Lawrence Wong, Ramon Rosal, Rebecca Rudolph, Matthew Frenkel, Anusha Thadi, William F. Morano, Wilbur B. Bowne, Matthew R. Pincus, Josef Michl

Department of Surgery Faculty Papers

PNC-27, a 32-residue peptide that contains an HDM-2 binding domain and a cell-penetrating peptide (CPP) leader sequence kills cancer, but not normal, cells by binding to HDM-2 associated with the plasma membrane and induces the formation of pores causing tumor cell lysis and necrosis. Conformational energy calculations on the structure of PNC-27 bound to HDM-2 suggest that 1:1 complexes form between PNC-27 and HDM-2 with the leader sequence pointing away from the complex. Immuno-scanning electron microscopy was carried out with cancer cells treated with PNC-27 and decorated with an anti-PNC-27 antibody coupled to 6 nm gold particles and an anti-HDM-2 …

Hur Plays A Role In Double-Strand Break Repair In Pancreatic Cancer Cells And Regulates Functional Brca1-Associated-Ring-Domain-1(Bard1) Isoforms, Aditi Jain, Matthew Mccoy, Carolyn Coats, Samantha Z Brown, Sankar Addya, Carl Pelz, Rosalie C Sears, Charles Yeo, Jonathan R Brody

Department of Surgery Faculty Papers

Human Antigen R (HuR/ELAVL1) is known to regulate stability of mRNAs involved in pancreatic ductal adenocarcinoma (PDAC) cell survival. Although several HuR targets are established, it is likely that many remain currently unknown. Here, we identified BARD1 mRNA as a novel target of HuR. Silencing HuR caused a >70% decrease in homologous recombination repair (HRR) efficiency as measured by the double-strand break repair (pDR-GFP reporter) assay. HuR-bound mRNAs extracted from RNP-immunoprecipitation and probed on a microarray, revealed a subset of HRR genes as putative HuR targets, including the BRCA1-Associated-Ring-Domain-1 (BARD1) (p < 0.005). BARD1 genetic alterations are infrequent in PDAC, and its context-dependent upregulation is poorly understood. Genetic silencing (siRNA and CRISPR knock-out) and pharmacological targeting of HuR inhibited both full length (FL) BARD1 and its functional isoforms (α, δ, Φ). Silencing BARD1 sensitized cells to olaparib and oxaliplatin; caused G2-M cell cycle arrest; and increased DNA-damage while decreasing HRR efficiency in cells. Exogenous overexpression of BARD1 in HuR-deficient cells partially rescued the HRR dysfunction, independent of an HuR pro-oncogenic function. Collectively, our findings demonstrate for the first time that BARD1 is a bona fide HuR target, which serves as an important regulatory point of the transient DNA-repair response in PDAC cells.

National Trends In Pectus Excavatum Repair: Patient Age, Facility Volume, And Outcomes, Shale J. Mack, Brian M. Till, Charles Huang, Darshak Thosani, Uzma Rahman, Tyler Grenda, Nathaniel R. Evans Iii, Olugbenga Okusanya

Department of Surgery Faculty Papers

Background: There is limited data on the adult repair of pectus excavatum (PE). Existing literature is largely limited to single institution experiences and suggests that adults undergoing modified Nuss repair may have worse outcomes than pediatric and adolescent patients. Using a representative national database, this analysis is the first to describe trends in demographics, outcomes, charges, and facility volume for adults undergoing modified Nuss procedure.

Methods: Because of a coding change associated with ICD-10, a retrospective cohort analysis using the National Inpatient Sample (NIS) for patients 12 or older undergoing modified Nuss repair between 2016-2018 was possible. Pearson's χ2 and …

A Standardized Diagnostic Pathway For Suspected Appendicitis In Children Reduces Unnecessary Imaging, Roshan J. D'Cruz, Allison F. Linden, Courtney L. Devon, Jillian Savage, Arezoo Zomorrodi, Kirk W. Reichard, Arabinda Choudhary, Loren Berman

Department of Surgery Faculty Papers

Introduction:

Ultrasound (US) for the diagnosis of acute appendicitis is often nondiagnostic, and additional imaging is required. A standardized approach may reduce unnecessary imaging.

Methods:

We retrospectively analyzed all patients who had imaging for appendicitis in our emergency department in 2017 and evaluated patient characteristics associated with nondiagnostic US. Using these results, we developed a pediatric appendicitis score (PAS)-based imaging pathway and compared imaging trends prepathway and postpathway implementation.

Results:

A total of 971 patients received imaging for suspected appendicitis prepathway in 2017. Female sex, obesity, and low/intermediate PAS were significantly associated with nondiagnostic US, but not magnetic resonance imaging …

Detection Of Lung Carcinoma Arising From Ground Glass Opacities (Ggo) After 5 Years - A Retrospective Review, Elissa Herskovitz, Charalamobos Solomides, Julie Barta, Nathaniel R. Evans Iii, Gregory C. Kane

Department of Surgery Faculty Papers

Pure ground glass opacities (GGO) may indicate pre-invasive subtypes of lung carcinoma. These neoplasms typically demonstrate indolent patterns of growth; Fleischner Society guidelines recommend up to five years of serial imaging. Our aim was to determine the frequency of diagnosed carcinoma arising from GGO detected beyond 5 years of surveillance. We reviewed pathologic diagnoses of lung carcinoma (n = 442) between 2016 and 2018 of a tertiary academic hospital and National Cancer Institute-designated cancer center to identify all cancers that arose from ground glass opacities detected on CT scan. Of the 442 cases of lung carcinoma, 32 (7%) were found …

Acute Occlusion Of Aortic Endovascular Aneurysm Repair Stent Graft With Bilateral Limb Ischemia, Min Choi, Dawn Salvatore, Paul J Dimuzio, Michael Nooromid, Babak Abai

Department of Surgery Faculty Papers

Endovascular aneurysm repair has dramatically changed the management of abdominal aortic aneurysms as an alternative to open repair. However, complications can occur, including stent graft migration, kinking, and occlusion, leading to compromise of the excluded aneurysm walls and acute limb ischemia. In the present report, we have described a case of migration and kinking of an abdominal aortic stent graft in the main body that led to occlusion of the abdominal aorta and bilateral acute limb ischemia. The patient required emergent explantation of the stent graft and open repair of the abdominal aneurysm with a rifampin-soaked Dacron graft, which achieved …
