Paediatric Endocrinology, under the leaderships of Lawson Wilkins in the US and of Andrea Prader in Europe, started to take shape as a subspecialty in the 1960s. Since that time, paediatric endocrinology has developed at a tremendous speed, especially during the last 30 years, in line with increasing knowledge in the field of genetics and other basic sciences, as well as improved medications and technical facilities. Endocrine conditions encountered in childhood are diverse and show a wide spectrum that is in many aspects substantially different from endocrine diseases in adults and the elderly. Children are simply not little adults. Handling of paediatric endocrine disorders requires the special attention of medical specialists with significant background training in paediatrics, to understand all aspects of human growth and development, along with specialised training in paediatric endocrinology. Developmental issues, including sex differentiation, body growth, skeletal development, pubertal maturation, and neuropsychological development from the intrauterine period to adolescence and young adulthood, are specific paediatric issues that cannot be fully understood and managed without paediatric training as the basic medical background. Recognising, classifying, diagnosing, and managing disorders of growth and development are specific tasks for fully trained paediatric endocrinologists. At the European Academy of Paediatrics (EAP), a subsection of the European Union of Medical Specialists (UEMS; formerly CESP), each paediatric subspecialty is represented by a liaison officer within the Tertiary Care Working Group (TCWG). The EAP has its own legislation/constitution (Belgian/ EU law) representing the central unifying platform for paediatric training in Europe. One of the major goals of the liaison officers is to update the current syllabus and accreditation procedures for their subspecialty, aiming at harmonisation of paediatric training throughout Europe. ESPE has recently, in 2014, revised its training program and this was approved by the General AsPublished online: July 6, 2016 HORMONE RESEARCH IN PÆDIATRICS
