GR and GT are diamniotic monochorial preterm twins (32 GA), both AGA (GR: W -1 SDS, L -1.5 SDS; GT: W and L 0 SDS), with normal karyotype and array-CGH on amniotic fluid, with no major complications associated to prematurity. At birth GT presented bilaterally cryptorchidism associated with micropenis, GR presented normal male genitalia. In the first year of life a severe growth deceleration in length (from -3SDS to -5 SDS) was observed, mainly after six months of life in both ...

Objectives: Preterm infants often present CH characterized by delayed TSH elevation. We describe the clinical and biochemical features and the evolution of CH in preterm infants with delayed TSH elevation, detected by the second screening for CH.Material and Methods: All preterm infants born between 2007 and 2014 negative to the first screening (b-TSH<10 mcU/ml) at 2–5 days of life and positive to the second screening at 12–33 days (b-TSH&#...

Background: Dietary patterns have notably changed in Mediterranean countries during the last decades. Mediterranean diet (MeDiet) is associated with lower prevalence of cardiometabolic diseases.Objective and hypotheses: To assess adherence to MeDiet in children and adolescents with abdominal obesity during a comprehensive weight loss intervention.Method: Children and adolescents with abdominal obesity (waist circumference >p90)...

Background: Autoimmune hepatitis (AIH) and methimazole (MMI)-induced toxic hepatitis are both rare diseases in pediatric age.Case presentation: We present the case of a 15-year-old girl affected by idiopathic arthritis and autoimmune thyroiditis. The autoimmune thyroiditis was diagnosed at 13 years of age. At 15 years old she developed hyperthyroidism (TSH <0.01 mcU/ml, FT4 2.3 ng/dl, FT3 8.4 pg/ml, TRAb 18 IU/l) and was treated with MMI (0.28 mg/kg ...

Background: Lipoprotein lipase (LPL) deficiency is an autosomal recessive disease with deficient extrahepatic removal of blood lipoproteins.Objective and hypotheses: Primary LPL deficiency can be exacerbated by coexistent conditions such as diabetes, where relative or absolute insulin deficiency leads to an additional secondary LPL deficiency.Method: We describe two cases in which primary LPL deficiency overlapped with previously d...

Background: Neonatal screening strategies revealed an increase in hypothyroidism associated with an in-situ thyroid gland due to TSH receptor (TSHR) mutations. While there are many genetic and functional studies regarding TSHR mutations, few are found concerning the clinical course and long-term outcome of TSH resistance involving the pediatric population.Objective and hypotheses: To determine the impact of TSHR mutations on clinical course, biochemical ...

Background: Xhantogranuloma of the sellar region (XG) is a very rare brain tumor and is clinically and pathologically distinct from classical adamantinomatous craniopharyngioma, but the differential diagnosis is difficult because there are no typical neuroradiological signes. The characteristic and the outcome of XG in children remain still unclear.Objective and hypotheses: We aimed to describe a case report of XG and multiple pituitary hormone deficienc...

Background: An important issue in the management of congenital hypothyroidism (CH) is the best initial dose of levothyroxine (L-T4) in order to achieve optimal neurocognitive outcomes. Both European and American guidelines suggest an initial dose of 10–15 μg/kg per die but trials on long-term effects of different doses within this range are lacking.Objective and hypotheses: This was a multicenter randomized trial to ev...

Background: Congenital hypothyroidism (CH) is a heterogeneous disorder. While the great majority of cases are considered sporadic, the use of next generation sequencing (NGS) may bring significant advances in elucidating the underlying molecular mechanisms.Case presentation: We selected a family with three children affected by CH with gland in situ and diagnosed at neonatal screening: the index patient, his sister and his brother. Data at diagno...

Aggrecan is a structural glycoprotein of the extracellular matrix of cartilage present in the articular cartilage, growth plate and cartilage of the intervertebral disc. Biallelic pathogenic variants are the cause of aggrecan type spondyloepiphyseal dysplasia (OMIM#612813) while the presence of heterozygous pathogenic variants determine Kimberley type spondyloepiphyseal dysplasia (OMIM#608361) and short stature associated or not with acceleration of bone maturation and early o...
