The purpose of this app is to introduce you to common pathologies encountered in an emergency department. The narratives contained in the cases express opinion of the app developers, based on their medical training and current medical literature. The app is designed to reflect real life learning as if you were a radiologist sitting on a workstation and scrolling through the cases. This app is not designed to substitute medical advice from a health care professional. In the context of global health, people have a conception that knowledge flows from developed countries to developing countries. For example, doctors go from United States and other developed countries to developing countries such as Nepal to share their knowledge and educate the local doctors. However, we believe that there is knowledge and expertise that can flow from developing countries to developed countries. The cases in this app are all from Nepal. The team who made this app are all from Nepal and it is our humble attempt to educate people all over the world.
