SHOX haploinsufficiency (SHOX-D) is a cause of disharmonic short stature and a possible genetic cause of idiopathic short stature also in familial cases. We describe clinical, hormonal and genetic characteristics of patients with SHOX-D haploinsufficiency, followed and treated in the period 2014–2017, in a single Italian centre. The Rappold score was used to screen short children, to select those who needed a genetic analysis of SHOX gene by MLPA and sequencing. We select...

Introduction: Congenital adrenal hyperplasia due to 11 beta hydroxylase deficiency, is an autosomal recessive pathology that represents 5 to 8% of congenital adrenal hyperplasia. The predominant symptoms of this disorder are androgen excess’ features, including masculinization of female newborns and precocious puberty in male children. Approximately, two thirds of patients also have hypertension, which may or may not be associated with mineralocorticoid excess, hypokale...

Introduction: Paediatric brain tumours in the sellar-suprasellar region (SSR) are often associated with central diabetes insipidus (CDI), either at diagnosis caused by the tumour itself or during follow-up as consequence of treatments.Aims: To define the timing of CDI onset and radiological features on brain MRI in our cohort.Methods: We retrospectively analysed paediatric patients...

Background: ALS deficient (ALS-D) patients present severe IGFI and IGFBP3 deficiencies and variable degree of growth retardation. Heterozygous carriers for IGFALS variants, ALS-D relatives or a subset of ISS children, have levels of IGFI, IGFBP3 and ALS intermediate between ALS-D and wildtype (WT) subjects. This supports that IGFALS gene variants may affect ALS synthesis, secretion and/or function and could be responsible for the observed phenotype.<p cla...

Aim: The onset of the infancy-childhood growth spurt (IC spurt) is identical with the onset of the childhood component of the infancy-childhood-puberty growth model. The aim of this study was to determine the timing of IC spurt and to investigate the factors affecting it in healthy children.Materials and Methods: The files of 231 healthy children who were followed up regularly (at 0, 2, 4, 6, 12, 15, 18, 24, 30 and 36 months) at the Ista...

Background: Achondroplasia is a skeletal dysplasia being the most common cause of rhizomelic dwarfism.Case presentation: We present a 10 years old boy who was first diagnosed prenatally. He had a mutation c1138G>A in the gene FGFR3 in a heterozygotic constellation. His IGF1 levels and IGFBP3 were normal. Two stimulation tests for GH were performed with normal levels of the hormone. His psychomotor development was adequate for his age except for speec...

Background: Congenital glucose–galactose malabsorbtion is a rare autosomal recessive disorder of intestinal transport of glucose and galactose. It is characterized by watery diarrhoea, dehydration, failure to thrive, or early death without appropriate dietary treatment.Case presentation: The patient was 15 days old when he was admitted to the hospital because of continued, severe, watery, acidic diarrhoea and hypernatremic dehydration. The abnormal ...

Introduction: Persistent Müllerian duct syndrome (PMDS) is a rare disorder of sex development (DSD) characterized by the persistence of Müllerian derivatives, the uterus and/or fallopian tubes, in otherwise normally virilized boys. PMDS is caused by mutations in the genes coding anti-Müllerian hormone (AMH, PMDS type 1) or the AMH receptor (AMHR2 gene, PMDS type 2) and it usually presents as undescended testes (cryptorchidism) or inguinal hernia...

Introduction: Complete ALS deficiency (ALS-D), caused by inactivating mutations in both IGFALS gene alleles, presents severe IGF1 and IGFBP3 deficiencies associated to moderate growth retardation.Aim: To characterize the molecular defect in a family where the index case and his father presented short stature and IGF1 and IGFBP3 deficiencies.Methods: IGF1, IGFBP3, and GH serum levels were determined by CLIA, ALS by ELISA an...

Background: According to recent European and Russian monitoring hypospadias and cryptorchidism are the most frequent malformations of the urogenital system in children in the general population. Currently there is a lack of information about the impact of assisted reproductive technologies (ART) on the development of congenital malformations, including the urogenital system, although the presence of this abnormality could lead to male reproductive disorders.</...
