Surgery Publications

Background. Procurement of hearts from cardiopulmonary arrest and resuscitated (CPR) donors for transplantation is suboptimal. We studied the influences of donor factors and regional wait times on CPR donor heart utilization. Methods. From UNOS database (1998 to 2012), we identified 44,744 heart donors, of which 4,964 (11%) received CPR. Based on procurement of heart for transplantation, CPR donors were divided into hearts procured (HP) and hearts not procured (HNP) groups. Logistic regression analysis was used to identify predictors of heart procurement. Results. Of the 4,964 CPR donors, 1,427 (28.8%) were in the HP group. Donor characteristics that favored heart procurement …

Is The Consistency More Important Than The Ingredients For Treatment? Case Report For Eosinophilic Esophagitis, Dan W. Parrish, Shashank Sharma, Santhosh Kumar

Surgery Publications

Eosinophilic Esophagitis seems to be an ever-changing disease, from patient-to-patient and from year-to-year in the same patient. Improvements in these patients’ lives have been made with the realization that elimination of dietary antigens helped with symptom relief and treatment with topical steroids assisted in eradication of esophageal eosinophils.

This case study has two very important aspects that should be emphasized. The first is the realization that it may be consistency of the steroid mixture rather than the ingredients that infer the effectiveness of the EoE treatment, and the second aspect is the willingness of the medical team to listen to …

A Double-Blind Randomized Controlled Trial Comparing Effectiveness Of 0.2% Topical Nifedipine Versus 0.2% Topical Glyceryl Trinitrate In The Treatment Of Chronic Anal Fissure, Mark Michael Wekundah Siboe

Master of Medicine in General Surgery

Background: The medical management of chronic anal fissure varies among clinicians because no single treatment has yet approached an overall healing rate similar to lateral sphincterotomy. However, chemical sphincterotomy has the advantage of not carrying the presumed high risk of faecal incontinence. Glyceryl Trinitrate is commonly used in our practice with varied response. This study set out to evaluate the effectiveness of a locally compounded preparation of 0.2% topical Nifedipine in the treatment of chronic anal fissure and to compare the investigational product to 0.2% Glyceryl Trinitrate in overall healing rate and relieving pain. Design: Single centre, parallel, double-blind randomized …

The Incidence Of Early Upper Extremity Disability After Axillary Surgery In Patients With Early Breast Cancer, Karen Mbaabu

Master of Medicine in General Surgery

Background: The treatment of early breast cancer includes surgical removal of the tumor as well as evaluation of the axillary lymph node status. Axillary lymph node surgery, both sentinel lymph node biopsy and axillary lymph node dissection, is associated with upper arm morbidity that has been relatively understudied. The impact of this upper arm limitation has a direct effect on the patients’ quality of life. Determining the degree to which our patients experience this disability will enable the breast cancer unit to develop a prospective surveillance rehabilitative program.

Boning Up On Autophagy: The Role Of Autophagy In Skeletal Biology., Irving Shapiro, Robert Layfield, Martin Lotz, Carmine Settembre, Caroline Whitehouse

Department of Orthopaedic Surgery Faculty Papers

From an evolutionary perspective, the major function of bone is to provide stable sites for muscle attachment and affording protection of vital organs, especially the heart and lungs (ribs) and spinal cord (vertebrae and intervertebral discs). However, bone has a considerable number of other functions: serving as a store for mineral ions, providing a site for blood cell synthesis and participating in a complex system-wide endocrine system. Not surprisingly, bone and cartilage cell homeostasis is tightly controlled, as is the maintenance of tissue structure and mass. While a great deal of new information is accruing concerning skeletal cell homeostasis, one …

Surgical Margin Status After Breast Conservation Surgery At Aga Khan University Hospital, Nairobi, Ronald Wasike, B. Riogi

General Surgery, East Africa

The conservation of the breast in a woman after diagnosis of breast cancer plays a vital role in the overall management of the patient.

Update On Intra-Arterial Chemotherapy For Retinoblastoma., Mario Zanaty, Guilherme Barros, Nohra Chalouhi, Md, Robert M Starke, Philip Manasseh, Stavropoula I. Tjoumakaris, Carol L Shields, David Hasan, Ketan Bulsara, Robert H. Rosenwasswer Md, Pascal Jabbour Md

Department of Neurosurgery Faculty Papers

The tools for managing retinoblastoma have been increasing in the past decade. While globe-salvage still relies heavily on intravenous chemotherapy, tumors in advanced stage that failed chemotherapy are now referred for intra-arterial chemotherapy (IAC) to avoid enucleation. However, IAC still has many obstacles to overcome. We present an update on the indications, complications, limitations, success, and technical aspects of IAC. Given its safety and high efficacy, it is expected that IAC will replace conventional strategies and will become a first-line option even for tumors that are amenable for other strategies.

Conversion Of Cardiac Bypass Into An Extracorporeal Membrane Oxygenation Circuit: A Case From Pakistan, Riffat Rasheed, Ijaz Hidayat, Muneer Amanullah, Babar Hasan

Department of Surgery Docs

A 35 days old neonate with d-loop transposition of great arteries, underwent an arterial switch operation following which he developed hypotension attributed to left ventricular failure. During cardiopulmonary resuscitation decision was made to place him on cardiac bypass again. Due to limited resources and unavailability of a specialized extracorporeal membrane oxygenator machine, the CPB was modified and converted an ECMO. The neonate was successfully decannulated after 72 hours and discharged home after 3 weeks of the operation without any sequel. ECMO is a viable option in developing countries and may help in improving the outcome especially in neonatal congenital heart …
