Volume 6 Issue 4 2005
Objective: The aim of this study was to determine the rate of negative appendectomy in a company hospital in Nigeria. Background: Appendicitis is one of the most common abdominal conditions requiring surgical intervention. Appendectomy, like most surgical procedures, has its complications and therefore should only be undertaken when indicated. Case series have reported the incidence of negative appendectomy in Western nations. The purpose of this retrospective study is to evaluate the incidence of negative appendectomy in a Nigerian hospital, where all the operations were carried out by consultant surgeons. Methods: All case files of patients who received an appendectomy at Chevron Hospital in Warri, Nigeria between January, 1999 and December, 2003 were reviewed. Demographic data, symptoms and signs on presentation, intra-operative findings and histological reports on the excised vermiform appendixes were extracted from the case files and analyzed. Results: The incidence of negative appendectomy in this study was 16.1%; all nine patients that had negative appendectomy were female. Conclusion: The incidence of negative appendectomy observed at Chevron Hospital in Warri, Nigeria is lower than that reported by most studies; one factor may be that all the patients in the present study were evaluated and operated on by consultant surgeons.
Reentrant Supraventricular Tachycardia in a Pediatric Trauma Patient Masquerading as a Cardiac Contusion
Establishing the etiology of tachycardia in a trauma patient is often difficult. Pediatric trauma patients present an even tougher challenge. Cardiac contusion should be suspected when other more common traumatic injuries that produce hypoxia and blood loss are excluded. The diagnosis of cardiac contusion is notoriously difficult to make largely due to the controversy over the definition of the disease, and the lack of a true gold standard confirmatory test. Atrioventricular nodal reentrant tachycardia (AVNRT) is a common form of supraventricular tachycardia (SVT) that can also present a diagnostic challenge to emergency physicians. While electrophysiologic studies are the gold standard for confirming the diagnosis, there are certain aspects of the history, electrocardiogram (ECG), and responses to cardiac maneuvers that strongly suggest the diagnosis. We present the case of a pediatric trauma patient that presented with new onset AVNRT masquerading as cardiac contusion.
