Background: High amounts of protein in meals increase blood glucose in patients with type 1 diabetes. Fat delays the increase of blood glucose. Till now we do not know the amount of insulin necessary to prevent the increase of blood glucose after a fat and protein rich meal (FPRM).Aim: To find the Insulin dosage to normalize glucose level after a FPRM.Patients: Sixteen patients with type 1 diabetes (mean±SD; Age 19.7±2.7 ...

Background: Accumulation of fat mass in the development of obesity may result from hypertrophy and/or hyperplasia and is frequently associated with adipose tissue (AT) dysfunction in adults. However, the onset and mechanisms of AT dysfunction are not entirely understood.Objective and hypotheses: We assessed composition, function, lipolysis, and inflammation in 171 AT samples from lean and obese children and adolescents (aged 0 – 18 years) to evaluat...

Background: The incidence of non-alcoholic fatty liver disease (NAFLD) is dramatically increasing among children worldwide. The gold standard for diagnosis is the liver biopsy. Reliable serum markers are lacking. Recently, circulating miRNAs have been studied as biomarkers of disease progression. Specifically, miR-122 was proposed as predictive marker for liver disease in adults, while no data are available for children.Objective and hypotheses: To inves...

Background: Magnetic resonance imaging (MRI) of the hypothalamic-pituitary area is extremely useful in the investigation of patients with central diabetes insipidus (CDI) due to infiltrative processes.Objective: We aimed to associate pituitary stalk thickness with the etiology of CDI and hormone deficiencies.Method: A retrospective single-center study of 15 patients (four boys and 11 girls) with CDI was performed and clinical-epide...

Human growth is a complex trait. A considerable number of gene defects have been shown to cause short stature, but there are only few examples of genetic causes of non-syndromic tall stature. Besides rare variants with large effects and common risk alleles with small effect size, oligogenic effects may contribute to this phenotype. Exome sequencing was carried out in a tall male (height 3.5 SDS) and his parents. Filtered damaging variants with high CADD scores were validated b...

Background: Very tall people attract a lot of attention and represent a clinically and genetically heterogenous group of individuals. Identifying the genetic etiology can provide important insights into the molecular mechanisms regulating linear growth.Methods and Results: We studied a three-generation pedigree with several isolated (non-syndromic) tall members by whole exome sequencing; the tallest man had a height of 2...

Objectives: Diazoxide is first line treatment for hypoglycaemia due to hyperinsulinaemic hypoglycaemia (HH). However, the FDA has raised serious concerns regarding diazoxide-induced pulmonary hypertension (PH) in 2015. Although sporadic cases of PH have been reported, no HH cohort has been systematically characterised to understand severity and risk factors for diazoxide-induced PH.Methods: To investigate the onset, progress and associated factors in PH,...

Background: Sp7, also known as Osterix (Osx), is a zinc-finger transcription factor, essential for osteoblast differentiation and bone formation. While bone formation is absent in Osx knockout mice, human loss of function mutations lead to impaired bone formation and cause recessive osteogenesis imperfecta, type XII (OMIM 613849 ).Case: The 5-year-old son of non-consanguineous parents presented with multiple long bone fr...

Background: Osteoporosis is a complex disorder, influenced by both environmental and genetic factors. Primary osteoporosis is a rare early onset disorder with high morbidity and mortality. Wnt signaling pathway has been shown to be involved in the regulation of bone remodeling.Case: Native Argentinean boy born from a consanguineous family with history of retinal detachment in the maternal line. Delivered at term, birth weight 2900 g (−0.95 SDS), bi...

Background: Hypothalamic obesity (HyOb) is a disease characterized by weight gain resistant to lifestyle changes and dietary restriction. The main clinical findings are hyperfagia and decline of satiety, high levels of insulin and an increase of adipogenesis. The major problem for these patients is that conventional treatments, either medical or surgical are not succesful and have variable results.Objective and hypotheses: We aim to describe the natural ...
