Rescue of a Child with Fatal Cardiothoracic Injuries from an Air Gun: A Case Report

Background: Mortalities resulting from firearms to the chest are still common worldwide. Although relatively uncommon compared to other age groups, gunshots that occur in children are fatal catastrophic events especially those that penetrate the thoracic cage. Air guns (pellets) are less devastating than conventional fatal firearms, but they can be fatal particularly in children. Case presentation: We present successful management for a child presented with major cardiothoracic injuries caused by an air gunshot (pellet) that penetrated the chest and passed through the heart and lung to the posterior mediastinum. Conclusions: The young age and penetration into the thoracic cage could make air guns as lethal as conventional firearms

Price Discrimination in Practice: The Market for Drugs in Egypt and the U.S.

This paper attempts to analyze the medical and economical reasons that cause a difference in the price elasticity of patients' demand to drugs between Egypt and the United States of America. The study was based on two medicines produced by Pfizer (Lipitor and Viagra), with both of them available in Egypt as well as the United States. The result of this study reflected that Egyptians are more sensitive to the changes in price relative to Americans for both Lipitor and Viagra because of different economical and medical factors.Price Discrimination, Pharmaceutical Industry

Statistical Intercell Interference Modeling for Capacity-Coverage Tradeoff Analysis in Downlink Cellular Networks

Interference shapes the interplay between capacity and coverage in cellular networks. However, interference is non-deterministic and depends on various system and channel parameters including user scheduling, frequency reuse, and fading variations. We present an analytical approach for modeling the distribution of intercell interference in the downlink of cellular networks as a function of generic fading channel models and various scheduling schemes. We demonstrate the usefulness of the derived expressions in calculating location-based and average-based data rates in addition to capturing practical tradeoffs between cell capacity and coverage in downlink cellular networks.Comment: 5 pages, 7 figures, conferenc
