Trends In Reconstructive Surgery Following Mastectomy At A Single Institution Between 2011 And 2015, Jessica Barton, Jaclyn Malat, Sergio Perez, Michael T. Brown

Research Day

Current trends show that same-day breast reconstruction after oncologic breast surgery is increasing. Data regarding the factors contributing to this increase in oncoplastic surgery is lacking. We examine the timing and type of reconstructive surgery following mastectomy at Reading Hospital between 2011 and 2015. We hypothesized that the majority of women would choose immediate reconstruction rather than delayed reconstruction following mastectomy and that the number of reconstructive surgeries would increase from 2011 to 2015 correlating with the increase in availability and popularity of oncoplastic breast procedures. This retrospective study looked at a total of 579 patients, 129 of which underwent …

A Correlative Blood Assay To Monitor Patients At Risk For Chemotherapy-Induced Peripheral Neuropathy, Angeleah Dadivas, Kinjal Parikh, John Kennedy, Amy Brady, Margaretha Wallon

Research Day

Introduction: Chemotherapy-induced peripheral neuropathy (CIPN) is a disabling side effect of platinum-based chemotherapies like cis-, oxali- and carboplatin. While not all patients experience this effect, those that do are at risk for lifelong neuropathy. Platinum-based therapies cause bursts of reactive oxygen species (ROS), which can trigger structural changes in peripheral nerves including neuronopathy, axonopathy and/or myelinopathy. Glutathione, an antioxidant, plays an important role in redox homeostasis. The recycling of glutathione can be determined by the ChemoTox assay and the aim of this study was to examine its ability to predict CIPN.

Methods: Blood drawn from consented and chemotherapy …

Use Of A Custom Macro In Analysis Of Rat Sciatic Nerve Sections, Daniel R. Whiteman, Peter Tang, Hongkyun Kim, Clifford Voight, Mark C. Miller

Research Day

Introduction: Technology is a powerful analytic tool. This abstract outlines the use of a custom macro to analyze rat sciatic nerve histology sections as part of a larger study to evaluate functional and histologic outcomes after segmental nerve injury. The problem facing analysis of nerve sections is that the microscopic features of a nerve, such as the individual axon, cannot be viewed on the same scale as the entire nerve bundle. The goal of this analysis was to extrapolate the average total values of axon count, axon density, fiber diameter, and myelin thickness on a nerve section image taken at …

Plastination Procedure @ Pcom: Current Practice And Future Uses, Derek D. Jolley, Vishwant R. Tatagari, Kerin M. Claeson

Research Day

Introduction: Since its invention by German anatomist Gunther von Hagens, the process of forced-impregnation plastination of organic specimens has become the standard for the preservation of biological tissue specimens. This practice serves as the most practical method to preserve these specimens for study and is utilized at PCOM regularly for this purpose. During the steps of plastination, aqueous and lipid tissues are replaced by a curable polymer to produce plastinates that do not decompose, can be handled without gloves, and retain most characteristics of the original specimens. For decades, PCOM used this method to prepare a permanent teaching collection …

A Case Series: Pre-Operative Internal Maxillary Artery Embolization Before Temporomandibular Joint Reconstruction, Amber Valeri, Joseph Georges, Carl Bifano, Hayan Dayoub, Hamza Shaikh

Research Day

Introduction: Temporomandibular joint (TMJ) ankylosis is an often-disfiguring pathology causing significant reduction in mandibular mobility leading to disability in mastication, digestion, speech, and oral hygiene. Caused by trauma, radiation, infection, and iatrogenic injury, TMJ ankylosis requires complete excision of the ankylosing mass following by arthroplasty. Substantial hemorrhage during this procedure, up to 3.7L, resulting from injury to the internal maxillary artery (IMA) as it courses around the ankylosing mass may occur. There are few data to recommend pre-operative IMA embolization, though a case series describing two patients who underwent the procedure describes significant decrease in intra-operative blood loss. Our aim …

Endovascular Intervention And Management Of Pediatric Mandibular Arteriovenous Malformation: A Case Report, Craig Schreiber, Hamza Shaikh

Research Day

Arteriovenous malformation of the mandible are a rare and potentially life threatening entity. Exsanguination from these lesions is a well documented event. Management of these lesions is unfortunately unclear and unstandardized due to their rare occurrence. Their presentation is wide and varied ranging from complaints of a loose tooth to acute hemorrhage and shock. Currently a multidisciplinary approach that typically involves input from oral maxillofacial surgeons (OMFS), otolaryngologists, and endovascular neurointerventionalists is required to manage these lesions. Often these lesions require both endovascular intervention and surgical resection. Due to the lesions high rate of recurrence and proximity to vital structures, …

TBI refers to a disruption of the brain’s normal functioning as a result of an acute external force. The most common causes for a TBI include falls, vehicular accidents, struck by or against an object, and assaults. The incidence for each cause of a TBI changes with respect to age. Severity of a TBI is determined using the Glasgow Coma Scale, which monitors the patient’s eye movements, verbal response and motor …

Neurobehavior In Humans And Its Role In Alzheimer's Disease, Aghilas Belkadi, Sarah Levin Allen

Research Day

In a neurobehavioral lens, a human is defined as the balance of the mind, body, and brain. These systems function on their own and influence each other in a dynamic equilibrium. Interactions between these systems are observed in every aspect of life. A pathological example of this relationship is that depression, a state of mind, can increase the risk of developing cardiovascular diseases. By studying a neurobehavioral model of health, empirical links between psychology and neurobiology can be uncovered. The basis of this capstone is to understand how neurobehavior works in clinical practice. This capstone project involved observation of seniors …

Modulation Of Nitric Oxide Release In Cultured Human Umbilical Vein Endothelial Cells By Myristoylated-Pkc Epsilon Activator/Inhibitor Peptides, George Ajene, Tameka Dean, Chantel Thompson, Wesley Hwang, Francis Jenney, Robert J. Barsotti, Qian Chen, Lindon H. Young

Research Day

Protein kinase C epsilon (PKCε) is known to increase endothelial nitric oxide synthase (eNOS) activity and subsequent nitric oxide (NO) release via phosphorylation at serine 1177 of eNOS in previous in vitro and in vivo animal studies under normoxic conditions. However, the role of PKCε regulating eNOS activity and NO release is not well known in human endothelial cells. Moreover, understanding the role of PKCε in regulating eNOS activity would be essential in the clinical setting of myocardial infarction. Re-establishing blood flow after thrombus removal results in endothelial dysfunction and is characterized by decreased NO bioavailability and excess reactive oxygen …

Research Day

When wound healing of cutaneous tissue becomes problematic, it increases patient morbidity associated with increased infection, demand on medical resources, and asserts a profound detrimental effect on the individual’s quality of life. Currently, there are limited effective strategies for addressing chronic cutaneous wounds. The study reported here is based upon the understanding that individual skin wounds may preferentially require differing proteinaceous precursors during specific phases of skin wound repair and calls attention to the possibilities in the reexamination of traditional treatments such as plant and animal-derived substances among many others. This study aimed to determine if, and which, amino acid …

The Effect Of Caffeic Acid Phenethyl Ester (Cape) On H2o2-Induced Oxidative Stress In Cultured H9c2 Cells Compared To Common Antioxidants, Dylan Lefkowitz, Robinderpal Sandhu, Alisa Kim, Andrew Castellano, Peter Wieczorek, Robert J. Barsotti, Lindon H. Young, Qian Chen

Research Day

Caffeic Acid Phenethyl Ester (CAPE) is a natural compound that has previously exhibited anti-proliferative, anti-inflammation and antioxidant activities. However, CAPE’s effects have not been fully elucidated in myoblasts under oxidative stress. We compared the effects of 24 hour pretreatment of CAPE to several known antioxidants (caffeic acid, vitamin C, and trolox) in H9c2 cells following oxidative injury by hydrogen peroxide (H2O2). H9c2 cells incubated with H2O2 treatment (100-700 μM, n=4) for 24 hours dose-dependently reduced cell viability (assessed by a cell counting assay). Compared to the reduction in viability from H2O2 500 μM treatment (22 ± 4%), H9c2 cell viability …

Epithelioid Glioblastoma Presenting As Aphasia In A Young Adult With Ovarian Cancer: A Case Report, Megan M. Finneran, Joseph Georges, Michael Kakareka, Ryan Moncman, Miriam Enriquez, Alan Turtz, Steven S. Yocom, H Warren Goldman, James Barresse

Research Day

Background: Epithelioid glioblastoma (eGBM) is a recent addition to the World Health Organization’s classification of central nervous system (CNS) tumors. This rare lesion has a predilection for younger patients, can mimic metastatic disease on preoperative imaging and intraoperative pathology, and portends a poor prognosis due to propensity for leptomeningeal dissemination.

Case Description: We discuss a case of a young woman with a history of ovarian cancer who presented with seizure and a new ring-enhancing left temporal brain lesion. The patient underwent gross-total surgical resection of this lesion, during which frozen section suggested metastasis. However, pathologic interrogation showed pleomorphic epithelioid cells …

Fluorescence-Guided Stereotactic Biopsy: A Proof-Of-Concept Study, Robert Lynagh, Joseph Georges, Mark Ishak, Brandon Boyer, Steven S. Yocom, Denah Appelt

Research Day

Introduction: Histopathological diagnoses are often necessary for treating neuro-oncology patients. However, stereotactic biopsy (STB), a common method for obtaining tissue from deep or eloquent brain regions, fails to yield diagnostic tissue in approximately 10% of cases. This can delay initiation of treatment and may result in further invasive procedures for patients. Here, we evaluate if coupling in vivo optical imaging with a STB system can identify diagnostic tissue at the time of biopsy.

Methods: A minimally invasive fiber optic imaging system was developed by coupling a 0.65mm diameter fiber optic fluorescence microendoscope to a STB system. Human glioma …

Penoscrotal Transposition: A Cadaveric Review, Paul Lecker, Dominic Parfianowicz, Jayaram Kumaraswamy, Sean Deangelo, Michael Mcguinness

Research Day

Introduction: With only 20 documented cases, the congenital malformation known as complete extreme penoscrotal transposition with an intact scrotum, midline raphe, and absence of hypospadias is an extremely rare abnormality. Penoscrotal transposition occurs when the scrotum fuses above the penis for a complete abnormality or does not fuse at all for an incomplete abnormality. This failure of the scrotum to descend below the penis occurs during development, when the genital swellings fail to descend below the penis and fuse. The irregularity has been known to follow an X-linked recessive pattern in some cases. In others, it results from a …
