Welcome to Top Hat Tutorials. This app was designed by students and doctors, for students and doctors as a study aid and reference tool for all aspects of the clinical examination in medicine and surgery. The clinical examination for each system is laid out in an easy to navigate format. Integrated videos, photos and diagrams all help the student or revising doctor to understand what they need to do, how to do it and why they are doing it. Do you need to revise murmurs before entering a cardiology ward, or refamiliarise yourself with the cranial nerves before a neurology ward round? With pictures integrated throughout the text, you will have rapid access to all of your clinical notes right in your pocket.
