There is also a new multiple choice question chapter with cross-references to the text, as requested by many readers of the first edition, thus providing an aide-memoire for those undergoing speciality examinations.

The second edition continues to meet this need as well as providing a ready source of reference for non-specialists including paediatricians and nurses. Like the first edition, the second is accessible and concise with a visual format characterised by extensive use of colour illustrations, flow charts and diagrams.
