Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: To investigate the frequency of IGF1R mutations in a cohort of patients with pre- and/or postn...

Introduction: In children with classical congenital adrenal hyperplasia(CCAH) linear growth allows monitoring metabolic control. Precocious puberty could compromise their growth. There are few studies in patients with CCAH diagnosed by neonatal screening(NS) about this subject.Aims: To analyze linear growth and precocious puberty in children with CCAH detected by NS.Method: Thirty-...

Introduction: Nephroblastoma or Wilms tumor is the most common pediatric abdominal malignancy. Typically, it is found in children younger than 5 years old, girls being more likely to have Wilms tumor than boys. The etiology of the disease is genetic, due to alteration in the development of the genitourinary tract.[1] Treatment is represented by surgery (unilateral nephrectomy), chemo- and radio-therapy. Paraneoplastic endocrine disorders may occur, but there a...

We present the cases of a 3 yo girl diagnosed with precoccious puberty, with a personal history of premature telarchy, genital hair development and vaginal blood discharge at 1yo 2mo, currently in treatment with GnRH agonist, and the case of her younger sister, aged 1 yo, who also presented with premature telarchy. They have 2 older siblings, both of them are clinically healthy boys. Their mother and paternal aunt had normal pubertal development. No other history from females ...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...

Background: A twin pregnancy with a coexisting complete hydatiform mole and a healthy fetus is rare, with an incidence of 1 in 22.000-100.000 pregnancies. Associated with this condition are potencially serious maternal and fetal complications.Case Report: A 32 year old pregnant woman presented with clinical features of hyperthyroidism, confirmed by laboratory. An ultrasound scan revealed a complete hydatiform mole (CHM) ...

Brother 1: 7 years old boy, with right genu valgum and short stature (−2,11 DS); X ray shows rickets features. Plasmatic Calcium 9.3 mg/dl; phosphate 2.5 mg/dl; Alkaline phosphatasas 460 U/l; Parathyroid hormone 83 pg/ml; 25OH Vitamin D 24 ng/ml. Urine calcium 159 mg/24 h (9.2 mg/K per day); Urine phosphate 870 mg/24 h; TmP/GFR 2.6 (NV:3.8 −5.0); proteinuria 100 mg/dl.Brother 2: 4 y.o boy with frequent respiratory diseases in infant period. G...

Background: A 33-year-old woman with a history of adrenocortical carcinoma (ACC), surgically treated aged 4, presented for prenatal screening at 20 weeks gestation. Ultrasound examination identified that the female foetus had a 3-cm adrenal lesion. She had a positive family history for multiple-endocrine-neoplasia-type 2/MEN2 (paternal grandmother) and her father’s cousin was diagnosed with ACC and Li-Fraumeni syndrome (LFS) at 30 year old. Calcitonin, PTH and cathecholam...

Background: Although metabolically obese normal weight (MONW) adults are at increased risk of type 2 diabetes and cardiovascular disease (CVD), little is known regarding MONW children.Objective and hypotheses: To characterize lifestyle habits and insulin dynamics of MONW children.Method: Caucasian youth (n=630) aged 8–10 years, with at least one obese biological parent, were studied (QUALITY cohort). We defined MONW c...

Background: Lifestyle interventions show a long lasting weight reduction in only 10–20% of obese children and adolescents. Leptin as one major player within the central regulation of food intake and energy expenditure is most likely to mediate the endogenous drive for weight regain.Objective and hypotheses: To estimate weight regain after weight loss and the role of leptin in regain.Method: We included 153 obese children/adole...
