It is a great pleasure for me to be the editor of the book Contemporary Pediatrics. Nowadays; there is lot of classical pediatric text books describing various well-known topics. In these kinds of text books, there have always been similar topics, which are written with the same styles. Nevertheless, in this book volume, beyond classical themes, a different approach was made to current pediatric issues and topics. This volume, as understood from its title, describes nutritional infant health and some interesting topics from pediatric subspecialties such as cardiology, hemato-oncology and infectious diseases. .
