Paediatric endocrinology started its independent development early in the general development of this specialty, with a strong focus on research and clinical excellence. Slovenian paediatric endocrinology was an integral part of the European paediatric endocrinology from its beginnings and a founding member of the first ‘International Study Group for Diabetes in Children and Adolescents’. After the pioneering work of Prof. Lev Matajc, Prof. Ciril Kržišnik firmly integrated the Department of Pediatric Endocrinology, Diabetes and Metabolic Diseases at the University Children’s Hospital in Ljubljana in the international scientific community. In the last decade, the department participates in cutting-edge research and provides clinical services at highest international standards. Pediatrična endokrinologija je začela s svojim neodvisnim razvojem zgodaj v splošnem razvoju te specilanosti, z izrazitim poudarkom na raziskovalnemu delu in klinični odličnosti. Slovenska pediatrična endokrinologija je bila že od začetkov evropske pediatrične endokrinologije njen sestavni del, še posebej kot soustanoviteljica prve mednarodne skupine ‘International Study Group for Diabetes in Children and Adolescents’. Po pionirskem delu prof. dr. Leva Matajca je prof. dr. Ciril Kržišnik KO za endokrinologijo, diabetes in bolezni presnove Pediatrične klinike v Ljubljani trdno vpel v mednarodno znanstveno skupnost. V zadnjem desetletju KO sodeluje pri vrhunskem raziskovalnem delu in zagotavlja klinično oskrbo po najvišjih mednarodnih standardih.
