Introduction: Brain tumors are the most common solid neoplasm in children, and treatment often includes high-dose irradiation of the central nervous system (CNS). Although not universal, growth hormone deficiency (GHD) is a very common endocrine late effect after CNS irradiation in childhood. The consequences of GHD in adults are many e.g., reduced bone mineral density, fatigue, decreased lean body mass and adiposity, which implies that adults with severe GHD ...

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...

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...

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...

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...

Background/aim: Osteoporosis is a known complication in adults with type 1 diabetes mellitus (T1DM), but whether the bones are affected in children and adolescents with T1DM remains controversial. The study aim was to evaluate bone mineral density (BMD) in children and adolescents with T1DM and identify risk factors associated to lower BMD.Method: In a single-center cohort of children and adolescents with T1DM, BMD was examined by dual-energy X-ray absor...

Background: Congenital hyperinsulinism (CHI) is a rare heterogeneous disease. Genetic testing is crucial as identifying the underlying aetiology can guide clinical management.Objective and hypotheses: We investigated the clinical characteristics and genetics of 20 Ukrainian patients with CHI.Methods: Routine clinical and laboratory investigations were performed on 20 patients with hypoglycemia and unsuppressed C-peptide and p-insul...

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...

Background: Congenital hyperinsulinism (CHI) is a rare, heterogeneous disease with a transient, recurrent or persistent course. Transient CHI (tCHI) is considered to be caused by non-genetic risk factors e.g. birth asphyxia and intrauterine growth restriction (IUGR), while persistent hyperinsulinism is known to be caused by mutations in at least nine genes: ABCC8, KCNJ11, GLUD1, GCK, HADH, SLC16A1, HNF4A, HNF1A and UCP2.Objective and hy...

Background: Klinefelter syndrome (KS) is a male genetic disorder defined by the karyo type 47,XXY. Adult males with KS are at increased risk for osteoporosis, based on androgen deficiency. Androgen replacement is standard in adolescent and adults with KS, but has not been used earlier in childhood. We performed a clinical trial to study the effects of childhood, low-dose androgen replacement on bone density in boys with KS.Objective and hypotheses: To me...
