Clinical approaches represent one of many methods to think through a clinical presentation, and narrow down a differential diagnosis. There are many conditions that can present with similar symptomatology. These presentations are not meant to contain an exhaustive list of differential diagnoses, but rather outline how to think through patient signs and symptoms, and understand some of the most common and important Paediatric conditions. There are many different ways to approach any clinical presentation, and these approaches are not meant to replace clinical judgement.
