Background: Heterozygous GNAS inactivating mutations cause pseudohypoparathyroidism type Ia (PHP-Ia) when maternally inherited and pseudopseudohypoparathyroidism (PPHP)/progressive osseous heteroplasia when paternally inherited. Mutations on the paternal, but not the maternal, GNAS allele are associated with intrauterine growth retardation (IUGR). Moreover, birth weights were lower with paternal GNAS mutations affecting exons 2–13 (including XL and Gαs) than with exo...

Background: In-vivo skeletal MRI imaging remains challenging due to the extremely short MR relaxation times (<1 ms) of protons bound to water in bone. However, each MRI sequence contains properties identifiable through feature-based recognition, highlighting characteristics relating to skeletal configuration. We thus present a novel statistical method for clinical 1.5 Tesla (T) MRI in quantifying trabecular microstructure and use HRpQCT to determine its accuracy.<...

Background: Children with ISS have an array of causes that lead to short stature and/or poor growth velocity. Genetic causes of short stature, notably SHOX mutations, can be associated with subtle skeletal disproportion with shorter limbs, manifesting as increased sitting-to-standing height ratios or SDS.Objective and hypothesis: Children with ISS and skeletal disproportions have a diminished growth response to GH treatment compared to chi...

Background: In the vast majority of cases, achondroplasia and hypochondroplasia are attributable to hotspot missense mutations in the FGFR3 gene. 96% of patients have a G(1138)A and 3% have a G(1138)C point mutation. We report on a family whose members have a deep intronic mutation that leads to a novel cryptic splicing variant of the FGFR3 gene, and via this pathway results in new pathogenicity manifesting as achondroplasia.Case...

Handling diabetes at a very early age is difficult, even more when a complementary diet has not yet started. There is increasing evidence supporting the use of CSII in infants but some tricks could be useful.Infant 1: 10 mo, admitted in cardiac arrest. ROSC after 3 minutes, severe DKA (pH 6,95). Transferred to PICU, received also plasma transfusions. Day 2: CGM Dexcom G6 was started and tests for pancreatic autoimmunity and genetic of ne...

Background: The gastrointestinal (GI) tract plays a central role in maintaining energy balance and body weight regulation. These functions are mediated by the secretion of gut hormones, including ghrelin, cholecystokinin (CCK), peptide YY(PYY), oxyntomodulin (OXM) and many other hormones. Some of them are orexigenic hormones that promote food intake, while others act as satiety signals and enhance insulin secretion from the pancreatic beta cells. Current evide...

Background: Paediatric pituitary adenomas comprise rare but challenging pathologies in children and adolescents related to their endocrine and neurological characteristics.Objective and Hypotheses: We aimed to describe a case report of growth hormone (GH)-secreting pituitary adenoma apoplexy.Method: a 11-year-old girl presented with fever, sudden headache with vomiting. She abruptl...

Backround: Craniopharingiomas are rare embryogenic malformations of the sellar and parasellar region with slow growth and high local recurrence rate. Due to their unfavorauble location, presurgical hypothalamic involvement and treatment-related hypothalamic damage is frequent and lead to hypothalamic syndrome.Objective: we compare weigh gain and growth pattern regarding to hypothalamic involvement of pediatric patients a...

Background: Beckwith-Wiedemann Syndrome (BWS) is an overgrowth disorder involving a predisposition to tumor development, etiologically connected with genetic/epigenetic dysregulation. The main features of BWS include omphalocele, macroglossia and macrosomia; however there is significant clinical heterogeneity. SHOX mutation is a frequent cause of short stature with high penetrance, but extremely variable clinical expression. The mean adult height is -2.2 SDS. The presence of m...

Background: AAAS is an autosomal recessive disorder characterized by adrenal insufficiency, alacrimia, achalasia and neurological symptoms. The disease-causing AAAS gene encodes for the ALADIN nuclear pore protein.Case presentation: Case 1: A girl (born to unrelated parents) presented at age 3.9 years with fatigue and hyperpigmented skin. Clinical examination was normal, clumsy gait was noted. Endocrine studies confirmed adrenal insufficiency (F=9 mg/ml,...
