Background: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Persistent hypoglycemia places patients at risk for adverse clinical outcomes, and current guidelines recommend maintaining plasma glucose >3.9mmol/l. CHI patients often have substantial, residual hypoglycemia and fail to meet treatment goals with currently available standard of care (SOC) therapies. In this study, we aimed to characterize...

Background: Congenital hyperinsulinism (CHI) is a common cause of hypoglycaemia in neonates, infants and children. CHI is a heterogeneous disease in terms of clinical presentation, genetics and histology.Objective and hypotheses: The aim of this study was to describe the clinical characteristics, genotype–phenotype correlations and treatment outcome of Russian patients with CHI.Method: A total of 90 children with CHI were iden...

Background: Insulinomas are very rare in childhood with sparse knowledge on the clinical aspects and the presence of Multiple Endocrine Neoplasia type 1 (MEN1).Methods: We conducted a multicentre retrospective review of patients diagnosed with insulinoma between 1995-2021. Clinical, biochemical, genetic, imaging and histological data were collected. In addition, follow-up and family data were obtained.<p class="abste...

Objective: The complex clinical phenotypes arising from HNF4A and HNF1A mutations are similar and include diazoxide-responsive CHI from infancy and maturity-onset diabetes of the young (MODY) from adolescence. We aimed to characterise the clinical and genetic aspects of a cohort of paediatric patients with HNF4A or HNF1A mutations.Methods: Patients from five international centres over ...

Background: Congenital Hyperinsulinism International (CHI) is an international non-profit organization focused on improving the lives of patients and families living with hyperinsulinism (HI). Despite many advances in the care of patients with HI, long term neurologic outcomes have not significantly improved, highlighting the need for CHI’s goals for robust and rapidly translatable research. We describe the development of a collaborative research network...

Extension of The Bone Health Index to Adults, and Reference Curves of Four Indices of Cortical Bone for Healthy Europeans

Martin David , Thodberg Hans Henrik

Background: The BoneXpert method for automated determination of bone age from hand X-rays has always included a determination of the Bone Health Index (BHI) from the cortical thicknesses in the metacarpals.Objective and hypotheses: The aim was to extend this so-called digital X-ray radiogrammetry method into adults, and present reference curves for BHI and three other indices: the metacarpal index, the Exton-Smith index and the volume-per-area (proportio...

Extension of Automated Bone Age Determination to the End of Puberty

Martin David , Thodberg Hans Henrik

Background: The BoneXpert method for automated determination of bone age (BA) from hand X-rays was introduced in 2009, covering the Greulich-Pyle BA range up to 17 years for boys and 15 years for girls.Objective and hypotheses: To present an extension of the BA range of the automated method up to 19 years for boys and 18 years for girls and to validate it against manual rating.Method: The extension was developed based on images fro...

Validation of a New Version of BoneXpert Bone Age in Children with Congenital Adrenal Hyperplasia (CAH), Precocious Puberty (PP), Growth Hormone Deficiency (GHD), Turner Syndrome (TS), and other Short Stature Diagnoses

Thodberg Hans Henrik , Martin David D

Background: The BoneXpert method for automated determination of bone age from hand X-rays is based on machine learning, so it lends itself naturally to be improved by adding more training data and using better learning algorithms. Currently, version 2 is running in 145 hospitals across Europe, and a new version 3 is rolled out in 2019.Objective and Hypotheses: The aim was to validate version 3 against manual ratings in r...

Efficacy and safety of bilateral epiphysiodesis in extremely tall adolescents

Aeppli Tim , Benyi Emelie , Wehtje Henrik , Sävendahl Lars

Background: Treatment options in extremely tall adolescents are limited. Bilateral epiphysiodesis has been reported to be a safe and effective method to reduce predicted final height. However, there is still limited data on final height and long-term safety.Objective: The aim was to assess the safety and efficacy of bilateral epiphysiodesis to reduce adult height in adolescent girls and boys with extreme tall stature.</p...

Hospitalisation in Children with Adrenal Insufficiency and Hypopituitarism: Is there a Differential Burden Between Boys and Girls and Between Age Groups?

Rushworth R. Louise , Chrisp Georgina , Falhammar Henrik , Torpy David

Background: There is a paucity of information on the utilisation of hospital services by children and adolescents with adrenal insufficiency (AI) and hypopituitarism.Objective and hypotheses: To determine the number of episodes of hospitalisation in children with adrenal insufficiency (AI) and hypopituitarism in Australia, and to analyse trends in these admissions.Method: An analysis of all admissions to Australian hospitals in pat...
