FOREWORD FROM SLEIMPN Eighteen months after the successful ICIEM in Brazil, our Society is gathering again, this time in Buenos Aires, Argentina, for the XI Congress of the SLEIMPN (May 12-15, 2019) For those of us who have been part of the SLEIMPN for many years, it is a pleasure to whiteness its growth, not only in the number of members, but also in que quality of the scientific production in our Region. The main theme of our Congress is “From NBS to treatment: a shared challenge”. I strongly believe that SLEIMPN is uniquely positioned to address this challenge, by exchanging knowledge and ideas to improve care in all aspects of the continuum that exists from a Newborn Screening (NBS) test to the treatment of patients and families affected by Inborn Errors of Metabolism (IEM). The scientific program includes plenary and parallel sessions covering relevant topics of IEM and NBS. Additionally, there will be three pre-congress courses on Nutrition, Genetics and Newborn Screening, as well as sponsored satellite symposiums. More than 30 faculty members, from around the world, will be generously sharing their knowledge. We hope that the record of the 279 abstracts of the free communications presented at this congress in this Special JIEMS Supplement will contribute to the field of IEM and NBS. Jose E. Abdenur President of SLEIMPN President of the XI Latin American Congress of Inborn Errors or Metabolism and Neonatal Screening FOREWORD FROM JIEMS The Journal of Inborn Errors of Metabolism and Screening, the official journal of the Latin American Society of Inborn Errors of Metabolism and Neonatal Screening, is pleased to introduce this special supplement with the abstracts accepted for presentation at the 11th Congress of the Latin American Society of Inborn Errors of Metabolism and Neonatal Screening (Buenos Aires, Argentina, May 12-15, 2019). In this special supplement you will find 279 abstracts submitted as free communications and accepted for presentation. In the index you will find first those abstracts accepted as oral communications and then those presented as posters, sub-divided in different categories. This supplement is also available online (open access) at the JIEMS website (www.jiems-journal.org). We hope that this JIEMS supplement contributes to disseminate the scientific output of this major event in the IEM field.
