Epidermal Growth Factor Mediated Healing In Stem Cell-Derived Vocal Fold Mucosa, Liliana Palencia, Amritava Das, Sean P. Palecek, Susan L. Thibeault, Ciara Leydon

Communication Disorders Faculty Publications

Background: The goal of vocal fold wound healing is the reconstitution of functional tissue, including a structurally and functionally intact epithelium. Mechanisms underlying reepithelialization in vocal folds are not known, although it is suspected that healing involves the interplay between several growth factors. We used a three-dimensional human embryonic stem cell-derived model of vocal fold mucosa to examine the effects of one growth factor, exogenous epidermal growth factor (EGF), on wound healing. Materials and methods: A scratch wound was created in the in vitro model. Rate of wound healing, epidermal growth factor receptor (EGFR) activation, and cell proliferation after injury …

Student Papers, Posters & Projects

INTRODUCTION: Contemporary demands on resident education call for integration of simulation. We designed and implemented a simulation-based curriculum for Post Graduate Year 1 surgery residents to teach technical and nontechnical skills within a clinical pathway approach for a foregut surgery patient, from outpatient visit through surgery and postoperative follow-up.

METHODS: The 3-day curriculum for groups of 6 residents comprises a combination of standardized patient encounters, didactic sessions, and hands-on training. The curriculum is underpinned by a summative simulation "pathway" repeated on days 1 and 3. The "pathway" is a series of simulated preoperative, intraoperative, and postoperative encounters in following up …

Epilepsy In Pakistan: National Guidelines For Clinicians, Fowzia Siddiqui, Tipu Sultan, Shahid Mustafa, Sarwar Jamil Siddiqui, Shaukat Ali, Abdul Malik, Zafar Sajjad, Saleem Barech, Rashid Jooma

Section of Neurology

Introduction: Epilepsy is one of the most common chronic neurological disorders requiring prolonged treatments and drugs. According to The World Health Organization (WHO), epilepsy is one of those serious brain disorders that affect not only the individual but has a deep impact on the family and society in general. Approximately 50 million people are affected with epilepsy around the world36, though proper epidemiological studies do not exist for Pakistan it is estimated that the prevalence of epilepsy is 9.99/1000. Highest prevalence is seen in people younger than 30 years of age, i.e. about 2 million people and 1/10th of the …

Combination Of Id2 Knockdown Whole Tumor Cells And Checkpoint Blockade: A Potent Vaccine Strategy In A Mouse Neuroblastoma Model., Lina Chakrabarti, Clifford Morgan, Anthony D. Sandler Jun 2015

Combination Of Id2 Knockdown Whole Tumor Cells And Checkpoint Blockade: A Potent Vaccine Strategy In A Mouse Neuroblastoma Model., Lina Chakrabarti, Clifford Morgan, Anthony D. Sandler

Surgery Faculty Publications

Tumor vaccines have held much promise, but to date have demonstrated little clinical success. This lack of success is conceivably due to poor tumor antigen presentation combined with immuno-suppressive mechanisms exploited by the tumor itself. Knock down of Inhibitor of differentiation protein 2 (Id2-kd) in mouse neuroblastoma whole tumor cells rendered these cells immunogenic. Id2-kd neuroblastoma (Neuro2a) cells (Id2-kd N2a) failed to grow in most immune competent mice and these mice subsequently developed immunity against further wild-type Neuro2a tumor cell challenge. Id2-kd N2a cells grew aggressively in immune-compromised hosts, thereby establishing the immunogenicity of these cells. Therapeutic vaccination with Id2-kd …

Department of Surgery Gibbon Society Historical Profiles

Edward William Alton Ochsner kept a plain, metal card file in which he recorded close to 50 years worth of medical experiences, research, and insights. The most populated topics were filed as "Cancer, Lung" and "Cancer, Bronchogenic." These reflected his areas of greatest interest, for which he would go on to produce groundbreaking work. Of his many lifetime accomplishments, he is perhaps best known for being the first to report a link between cigarette smoking and lung cancer. This was just one of the many ways in which Ochsner worked to effect social change. The establishment of the Ochsner Health …


An Ex Vivo Approach To Complex Renal Artery Aneurysm Repair, Noah T. Scherrer, Roberto Gedaly, Ramakrishna Venkatesh, Michael A. Winkler, Eleftherios S. Xenos Jun 2015

An Ex Vivo Approach To Complex Renal Artery Aneurysm Repair, Noah T. Scherrer, Roberto Gedaly, Ramakrishna Venkatesh, Michael A. Winkler, Eleftherios S. Xenos

Surgery Faculty Publications

Ex vivo repair technique for a complex renal artery aneurysm may have several advantages. Smaller incision size and use of minimally invasive techniques may decrease incisional morbidity and improve recovery time, especially in patients with a high body mass index. Improved visualization afforded by back-table methods may also be valuable when repair of aneurysms involving multiple branches is necessary. We report of a successful case of laparoscopic nephrectomy, followed by back-table aneurysmorrhaphy and autotransplant, in a patient with a renal artery aneurysm.

Understanding Nucleus Pulposus Cell Phenotype: A Prerequisite For Stem Cell Based Therapies To Treat Intervertebral Disc Degeneration., Hyowon Choi, Zariel I. Johnson, Makarand V. Risbud

Department of Orthopaedic Surgery Faculty Papers

Intervertebral disc (IVD) degeneration and associated low back pain (LBP) remains a major burden to our society without significant improvements in treatment strategies or patient's quality of life. While the recent cell-transplantation studies for treatment of degenerative disc disease have shown promising results, to better gauge the success and functional outcomes of these therapies, it is crucial to understand if transplanted cells give rise to healthy nucleus pulposus (NP) tissue. NP cell phenotype is unique and is defined by expression of a characteristic set of markers that reflect specialized physiology and function. This review summarizes phenotypic markers that mirror the …


Development Of A Guide By Postgraduate Residents On Receiving Feedback From Faculty In The Operating Theatre At Aga Khan University Hospital, David Karuri Maina May 2015

Development Of A Guide By Postgraduate Residents On Receiving Feedback From Faculty In The Operating Theatre At Aga Khan University Hospital, David Karuri Maina

Master of Medicine in General Surgery

Background: Direct observation of residents in clinical encounters by faculty and assessment for learning has now become a key component of postgraduate training programs. DOPS, a workplace-based assessment form, was designed to provide formative assessment and feedback about a trainee’s procedural skills. Interactions between residents and faculty are central to this learning process and are influenced by multiple factors both at faculty and resident levels as well as contextual factors. The feedback may be used by the receiver to contemplate behaviour change. The receptivity of the resident to the feedback is a key determinant as to whether the process to …

Surgery Faculty Publications

We document a 3-year-old healthy African American girl who developed malignant melanoma on her lower extremity. The clinical appearance offered little indication of the lesion’s severity (T4), and only the history of de novo presentation and disproportionate growth raised clinical suspicion. This case report highlights the subtle clinical findings of this condition and presents controversies related to surgical management of pediatric melanoma.
