Introduction: A condition that causes strong inhibition of growth hormone (GH) secretion is, among others, hyperglycemia; this phenomenon is used in the diagnosis of suspected GH excess by performing a GH inhibition test after oral administration of glucose (OGTT). In a healthy adult, it has been established that the nadir of GH concentration should not exceed 1 ng/ml (0.4 ng/ml in the case of sensitive tests). It is unclear whether the same standards should a...

Introduction: Congenital hypopituitarism is a heterogeneous disorder that involve combined pituitary hormone deficiencies.Patients and Methods: Longitudinal review of pediatric cases with congenital hypopituitarism follow up in a third level hospital.Inclusion criteria: patients under 18 years at diagnosis with combined pituitary hormone deficiencies....

Introduction: NS is a relative frequent cause of short stature (ST) in pediatrics and its diagnosis is based on a combination of typical facial features, ST, chest wall defects, cardiac defects, developmental delay, cryptorchidism, lymphatic dysplasia, and family history (“Van Der Burgt Criteria”, revised 2007). Around 50% of NS patients presents a pathogenic variant in the PTPN11 gene. The overlap with other conditions, phenotypic changes...

Introduction: Beta-thalassaemia major is an inherited anemia which requires chronic transfusions and is frequently associated with endocrine dysfunctions secondary to iron overload. The aim of this study was to identify the prevalence of various endocrine complications in beta-thalassaemia major children over a period of 14 years and the factors associated with them.Materials and methods: 61 children with BTM (mean age 12.23 years) registered at the Endo...

GHD diagnosis in neonates and infants is a challenge owing to the fact that GH pharmacological stimulation tests (GHST) are not approved at this age. In a retrospective study, we found that a random GH<6.5 µg/L confirmed GHD diagnosis in neonates with clinical suspicion of GHD with high diagnostic accuracy (1). The accuracy of GH and its surrogates of action have not been set for infants with current standardized immunoassays.Objective</...

Introduction: The Wilms tumor suppressor gene 1 (WT1) plays an essential role in urogenital and kidney development. Heterozygous germline mutations in WT1 have been classically associated with Denys–Drash (DDS) and Frasier syndrome (FS). Exonic missense mutations in the zinc-finger region are the cause of DDS and mutations affecting the canonic donor KTS splice site of intron 9 are the cause of FS. New phenotypes, as 46,XX testicular DSD...

The survival rate of young patients with cancer has greatly improved in the last decades, in part due to the introduction of new therapeutic agents and protocols.Chemotherapy may be associated with risk of ovarian dysfunction, permanent or transient amenorrhea, symptoms of ovarian insufficiency and infertility.It has been suggested that prepubertal ovary is less susceptible to deleterious effect of chemotherapy.<p class="abstex...

Background/Aims: Magnetic resonance imaging (MRI) is used to investigate the etiology of growth hormone deficiency (GHD). There is a close relationship between structural changes in the pituitary gland and clinical status.We aimed to investigate the relationship between MRI findings and clinical symptoms and treatment response in children with GHD.Methods: The study was conducted in nine Department...

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...
