Dear Colleague, Pediatric Endocrinology Reviews (PER) is a critical, peer-reviewed Journal, filling an existing gap in the pediatric endocrinological literature. It is aimed at practicing pediatricians, pediatric endocrinologists, pediatric diabetologists, pediatric gastroenterologists, neonatologists, pediatric gynecologists, nutritionists, sport physicians and pediatricians-in-training. The fast increasing amount of literature makes it impossible for hardworking physicians to keep up with academic and clinical medical advances. New electronic methodology serves masses of detailed information. PER will offer you compilations and analytical reviews of these data, trying to widen the horizon of its readers and to improve the care of children and adolescents. The appreciation of review articles by readers is seen by the very high citation (impact) factor of Review Journals compared to other Journals. Readers are encouraged to propose titles and own contributions. There are no handling or page charges. In addition, PER will have sections on: Correspondence (Letters); Book Reviews; Calendar of Meetings; Meeting Reports; Advertising. 4 yearly issues & 4 Supplements  Editor-in-Chief:      Zvi Laron, MD Associate Editors: Mitchell E.
