Background: Congenital hyperinsulinism (HI) is characterised by inappropriate insulin secretion despite low blood glucose which is commonly diagnosed in infancy (before the age of 12 months). Screening of the >20 known genes identifies a mutation in over 45% of cases. The likelihood of identifying a mutation in a known gene in individuals diagnosed after 12 months is not currently known.Aim: We aimed to identify the ...

The 1st lockdown from March to May 2020 probably led to an increase in the number of cases of idiopathic central precocious puberty in several European countries. Two Italian studies showed this, as well as a Spanish and a Turkish one. We performed a retrospective study with all the children who came to our department for a 1st appointment or a check-up for pubertal signs between 01/04/2017 and 31/03/2021. We checked the data of 765 files and kept only the children with a diag...

Background: Constitutional delay of growth and puberty (CDGP) is one of the most frequent norm variants in children presenting with short stature. Knowing the height, growth, and weight pattern of CDGP in the first years of life is important to distinguish CDGP from growth hormone deficiency (GHD) or other diseases.Methods: We studied height and weight in the first 5 years of life in 54 boys with CDGP including measureme...

Background: For children with retarded bone ages such as in constitutional delay of growth and puberty (CDGP) there are no specific methods to predict adult height based on bone age. Widely used methods such as Bayley-Pinneau (BP) tend to overestimate adult height in CDGP. Therefore, we aimed to develop a specific adult height prediction model for boys in pubertal age with retarded bone age >1 year.Methods</...

Background: Routine screening for Coeliac disease (CD) beyond the first year of diagnosis with Type 1 Diabetes Mellitus (T1DM) is controversial due to a paucity of high-quality evidence. The UK guidelines (NICE) only recommend screening at diagnosis with T1DM or if subsequently symptomatic; whereas the International Society for Paediatric and Adolescent Diabetes (ISPAD) recommends routine screening every 1 to 2 years.Objective and hypotheses: We hypothes...

Background: More than 20 gene loci are known to cause monogenic neonatal diabetes today. A definite mutation can be found in 65–70% of all cases. Mutations in the ATP sensitive potassium channel can frequently be treated by sulfonylurea. Glibenclamide is on of the drugs known to inhibit the bile salt export pump (BSEP). However most drug induced cholestasis cases are reported in adults.Objective and hypotheses: Glibenclamide is used frequently to tr...

Background: Obesity is a major feature in several syndromes. In patients with early-onset severe obesity, 7% harbour a single locus mutation.Objective and hypotheses: We report a 3.11 year old male patient with early onset obesity (BMI 29.9 kg/m2 >>P97), ongoing excessive weight gain, autoaggressive behaviour, and delayed speech development. No growth retardation or further dysmorphic signs. Early postnatal feeding difficulties require...

Background: Recently we described a family with several members having intrauterine and postnatal growth failure as well as signs of Silver–Russell syndrome (SRS) who carried a heterozygote nonsense mutation of IGF2. The patients had low IGF-II serum levels, but normal IGF-I serum levels.Objective and hypotheses: We aimed to estimate the diagnostic value of the IGF-II, IGF-I and IGFBP-3 measurements in the assessment of children with SRS.<p clas...

Background: The cardiovascular risk for children receiving treatment with GH has hardly been investigated. Therefore, we studied the relationships between GH treatment and carotid intima media-thickness (IMT), which is predictive for the cardiovascular diseases.Methods: We measured carotid IMT (four values) in 100 children (mean age 11.6±2.8 years, 63% male) treated with GH (GH deficiency 61%, SGA 31%, Turner syndrome 5%, SHOX deficiency 2%, Prader-...

Background: Long-acting somatostatin analogues have been reported to be an effective treatment option to prevent severe hypoglycaemia in children with severe diffuse congenital hyperinsulinism (CHI). Possible side effects include gallstones, growth retardation and necrotizing enterocolitis (NEC), the latter occurring in particular cases of newborns treated with octreotide. So far only short-acting octreotide is being used in early infancy, requiring multiple injections daily o...
