Background and aims: The aromatase inhibitor letrozole is used to improve final height in boys with predicted short stature by delaying bone age (BA) maturation due to suppression of estradiol levels. There are few data regarding its effects, especially when used as single medication.Methods: Ten pubertal boys with predicted low final height treated with letrozole 2.5 mg/d p.o. (no other medication) for up to 24 months were analysed for auxological, labo...

Background: Silver-Russell syndrome (SRS) is a heterogeneous condition characterized by intrauterine growth restriction, relative macrocephaly at birth, postnatal growth retardation, body asymmetry, feeding difficulties/ low body mass index and dysmorphic craniofacial features. SRS is caused by DNA hypomethylation at the H19/IGF2-imprinting control region (ICR1) on chromosome 11p15 or maternal uniparental disomy of chromosome 7 (mUPD7) in approximately 50% and 10%, respectivel...

Background: Achondroplasia and hypochondroplasia are more frequent types of skeletal dysplasia. De novo mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are the principal cause. More than 95% of the cases of achondroplasia result from a mutation G1138A (Gly380Arg). In hypochondroplasia we usually (50–70%) found the change C1620A y C1620G, N540K (Asn540Lys).Objective and hypotheses: We describe an skeletal dysplasia...

Background and aims: Glucocorticoid treatment may influence bone and muscle development in patients with congenital adrenal hyperplasia (CAH). This study evaluated bone mineral density (BMD), bone geometry and muscle mass longitudinally throughout childhood.Methods: 18 patients (ten males, eight females) with classical CAH were included. BMD, bone geometry and muscle mass were measured using peripheral quantitative computed tomography (pQCT) in prepubert...

Background: Several studies show impaired glucose tolerance at a certain number of years after start of growth hormone in SGA-children.Objective and hypotheses: To perform a longitudinal and cross-sectional evaluation of the oGTTs (glucose-insulin-pairs) in prepubertal GH-treated SGA-children and to evaluate if ISI and HOMA are effective surrogates for glucose tolerance and of prognostic value (0–1 year data).Method: In 81 pre...

Background: Vitamin D deficiency/insufficiency seems to occur frequently in children and teenagers but it is a matter of debate if limits (<20 ng/ml; <30 ng/ml) are correct. Besides its effect in bone metabolism Vit-D is also supposed to have a positive influence in diabetes mellitus 1 (DM1).Objective and hypotheses: To study 25OHD and iPTH values in a group of patients (pts) (n=57) with DM1 without Vit-D substitution (2011), with 1000 I...

Background: Type 1 DM is an autoimmune disease, characterized by destruction of the insulin-producing beta-cells in the islets of Langerhans. The absolute insulin deficiency leads to metabolic imbalance with hyperglycaemia, acidosis and proneness to ketosis. This acute disturbance can change thyroid hormone metabolism.Objective and hypotheses: To examine the influence of metabolic acidosis/ketoacidosis in type 1 DM on thyroid hormone levels.<p class=...

Background: Type 1 diabetes mellitus has three common presentations: Typical (hyperglycaemia with cardinal symptoms), ketoacidosis and asymptomatic hyperglycaemia.Case presentation: A 7.5-year-old girl with a history of bronchial asthma presented to the emergency department with acute-onset diabetic symptoms. The previous year she was admitted to the Paediatric Ward for a pneumonia complicated by pleural effusion. She then developed hyperglycemia (400 mg...

Background: Calcium homeostasis is primarily regulated by vitamin D. In the absence of the active hormone or a functional receptor, bones are inadequately mineralized, leading to the development of rickets. Vitamin D-dependent rickets type 2 (VDDR2) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) gene.Case Report: A 12-months-old girl was transported to the local hospital ED with a three-minute ...

Introduction: Besides an excessive, early-childhood weight gain, hyperphagia is the key symptom in patients with monogenic obesity. However, the assessment of hyperphagia is still challenging. Here, we applied the hyperphagia questionnaire developed for patients with Prader-Willi-Syndrome (PWS) to assess the severity of hyperphagia in patients with monogenic obesity.Methods: Pediatric patients with biallelic pathogenic l...
