The Power Of Outpatient Botulinum Injections In Preventing Hirschsprung Associated Enterocolitis, Wendy Jo Svetanoff

Research Days

Background: Hirschsprung associated enterocolitis (HAEC) is a potentially life-threatening complication, where the child often presents with obstructive symptoms. Failure of the internal anal sphincter (IAS) to relax is thought to play a role in these symptoms. Botulinum toxin (BT) injections assist in temporarily relieving obstructive symptoms due to IAS achalasia in patients with Hirschsprung’s disease following surgical pull-through. The use of BT may play a role in preventing HAEC episodes related to IAS dysfunction.

Objectives/Goal: Our aim was to determine the effect of scheduled outpatient Botulinum injections on the development of HAEC.

Methods/Design: A retrospective review between July 2010 – …

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 …

Brachial Artery Aneurysm After Arteriovenous Fistula Ligation Status Post-Kidney Transplant, Alyssa Imperatore, Justin Adibi, Rahul Sharma, Yury Bak

Rowan-Virtua Research Day

Arteriovenous fistulas (AVF) are the most common and effective method of receiving hemodialysis; However, these access techniques do not come without consequence. Aneurysmal degeneration after creation and even years after ligation of such AVF can occur. This is still considered a rare complication. A true brachial artery aneurysm has an overall incidence of 0.17% among peripheral artery aneurysms. Factors that increase incidence of this complication include trauma, age and immunosuppression. Research on this topic is becoming more prevalent, but more answers are still needed. Below is a case of brachial artery aneurysm presenting years after AVF ligation in a patient …
