Background: Third generation aromatase inhibitors have been used to increase predicted adult height (PAH) in boys but in girls only in McCune–Albright syndrome.Objective and hypotheses: We overcame the theoretical concern of secondary hyperandrogenism by combining anastrazole to an LHRH analogue in a 6-year prospective study to test whether the combination therapy could significantly improve PAH compared to inhibition of puberty alone.<p class="...

Background: GH treatment is effective in improving adult height (AH) in short children born Small for Gestational Age. If SGA children are short at the start of puberty, they could benefit from combined GH/GnRH Analogue (GnRHa) treatment.Objective and hypotheses: To determine the timing and progression of pubertal development in short SGA children, comparing GH treatment with combined GH/GnRHa treatment.Method: For the present stud...

Background: Isolated premature thelarche (IPT) is characterised by precocious breast development without any other signs of puberty.Objective and hypotheses: The aim of the study was to analyze hormonal activity of the pituitary – ovarian axis in girls with IPT.Method: 102 girls with IPT (Tanner stage 2–3), mean age 2±1.4 years (0.04–7 years), mean weight 12.3±4.3 kg, mean height 85.0±13.6 cm (45±...

Introduction: Kisspeptin is well known gatekeeper of puberty onset to date. However, several neuroendocrine factors are also discovered to be associated with puberty onset and, especially neuropeptide Y (NPY) and neurokinin B, participate in the neuronal network integrating reproduction. However, the interactions between neuroendocrine factors and the reproductive axis have not yet been fully explored. We report herein the expression profile of NPY gene and neurokinin B gene i...

Background: According to international guidelines Prader-Willi children during GH treatment must be closely monitored by polysomnography, ENT evaluation and IGF1 levels.Objective and hypotheses: The study aims to determine whether the modulation of GH therapy in children and adolescents with Prader-Willi Syndrome with a specific decisional score (POI score; Salvatoni A., Horm Res Paediatr. 2012) changes and to what extent the results of the therapy.<...

Context: Alterations in semen characteristics and Sertoli and Leydig cell function have been described in obese male adults. Whether these alterations occur before adulthood has not been fully evaluated.Objective and Design: Cross sectional study from 2010 to 2018 describing gonadic function in overweight-obese (ow/ob) boys through childhood and adolescence.Setting: Monocentric study in the Pediatric Endocrinology ...

Context: Cryptorchidism, a common consequence of HH, is treated with orchiopexy. We previously observed that continuous subcutaneous infusion of gonadotropins restored normal serum testosterone and inhibin B concentrations in two infants with hypogonadotropic hypogonadism (HH) and was associated with testicular descent in one.Objective: Test if subcutaneous gonadotropin infusion within the first year of life can allow testicular descent in eight boys wit...

Background: Different studies have underlined the role of anti-Müllerian hormone (AMH) and inhibin B as markers of the ovarian function in paediatric and adolescent patients with Turner syndrome (TS).Objective and hypotheses: Our study aims to verify the role of AMH in a cohort of patients affected by TS.Method: We analysed 23 TS patients, aged 2–34 years, describing their auxological parameters and the pubertal developme...

Introduction: The Covid-19 pandemic drastically modified social life and lifestyle in particular among children and adolescents, promoting sedentary behaviors and unhealthy eating habits. In this scenario, the effectiveness of the outpatient approach for pediatric obesity may decrease.Objectives: Aims of this study were to assess the rate and the factors associated with outpatient drop-out by comparing two groups of chil...

Background: Pseudohypoparathyroidism type 1a (PHP1a) is characterized by Albright hereditary osteodystrophy (AHO) and multi-hormone resistance, most commonly to parathyroid hormone (PTH) and thyroid-stimulating hormone. This rare disorder is caused by inactivating mutations involving exons 1–13 of the imprinted GNAS gene that encodes the alpha-subunit of the stimulatory G protein (Gαs). Due to paternal imprinting of Gαs transcripts, GNAS mutati...
