To read the full abstract: Horm Res Paediatr. 2019;92:1–14In March 2019, 46 international experts from 14 countries across 5 continents attended a 3-day workshop organized by the Growth Hormone Research Society (GRS) and produced this perspective on the diagnosis, management and therapy in children with short stature. In this context, this expert panel tackled almost all aspects related to the management of children with short stature, prov...

To read the full abstract: J Pediatr. 2019 Dec;215:192–198.Identifying the diagnosis in children with syndromic short stature and those with recognized genetic growth disorders is often challenging, as they may share many clinical features (1)(2). The candidate gene approach has many limitations in unveiling the genetic cause. Therefore, whole exome sequencing (WES) has been proposed to improve the diagnostic rate in children with short sta...

To read the full abstract: J Clin Endocrinol Metab, April 2020, 105(4):e1478–e1488Silver–Russell syndrome (SRS) is a rare condition associated with pre and postnatal growth retardation. The most common causes of SRS are 11p15 ICR1 loss of methylation (LOM) and maternal uniparental disomy of chromosome 7 (mUPD7). Almost all patients with SRS have a history of intrauterine growth retardation (IUGR) and may be born small for gestational a...

To read the full abstract: J Clin Endocrinol Metab. 2020 Aug 1;105(8):dgaa274.This retrospective study evaluated the long-term effects of GH treatment (median duration 6.7 years) in 63 girls with Turner syndrome (TS) whose GH doses were titrated to maintain IGF-I levels within the normal range. The median GH dose to maintain normal IGF-I levels was 33 (g/kg/day. Across all TS karyotypes, IGF-I titrated GH dosing led to a median adult height (AH)...
