Next Generation Sequencing and Precocious Puberty: A New Diagnostic Challenge to Identify the Molecular Basis of Complex Diseases

La Barbera Andrea , Provenzano Aldesia , Artuso Rosangela , Orlandini Valerio , Giglio Sabrina , Stagi Stefano

Background: Precocious puberty is defined as the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. This condition results from a constant and complex interplay between predisposing genes and environmental factors. To date, the molecular analysis are all focused on reproductive-endocrine disorders such as Kallmann syndrome and hypogonadotropic hypogonadism, while the genetic bases of pubertal timing are still unclear.<p ...

Prevalence of Organic Lesions in Males with Central Precocious Puberty

Pedicelli Stefania , De Matteis Sara , Scire Giuseppe , Cappa Marco , Cianfarani Stefano

Background: Organic lesions in males with central precocious puberty (CPP) have been reported in 40% of cases. This high prevalence decreases (20–29%) when patients with previously diagnosed alterations of central nervous system (CNS) are excluded. Reported predictors of organic lesions are age at puberty onset, bone age, BMI, LH peak response and testosterone levels.Objective and hypotheses: To determine the prevalence and type of intracranial lesi...

Hyperreninemic Hypoaldosteronism: Clinical and Genetic Features in Pediatric Patients

Capirchio Laura , Seminara Salvatore , Scalini Perla , de Martino Maurizio , Stagi Stefano

Background: Isolated hyperreninemic hypoaldosteronism due to aldosterone synthase deficiency is a rare autosomal recessive disorder linked to aldosterone biosynthesis defect (involving CYP11B2 gene). Its clinical presentation varies with age: during the first weeks of life it usually presents with salt-wasting syndrome (with severe hyponatremia, hyperkalemia, metabolic acidosis, vomiting, signs of dehydration) while in children it is usually characterized by failure to thrive,...

Bone Status in a Patient with IGF-I Receptor Deletion Syndrome: Bone Quality and Structure Evaluation Using DXA, pQCT, and QUS

Stagi Stefano , Pelosi Paola , Scalini Perla , Cavalli Loredana , Pantaleo Marilena , Lapi Elisabetta , Martino Maurizio de

Background: Various aspects of IGF1R defects have been analysed to date, but the effects of IGF1R haploinsufficiency bone status and metabolism were rarely investigated.Objective and hypotheses: To study bone metabolism and structure in a case of Insulin-like growth factor-I (IGF-I) receptor (IGF1R) gene deletion.Method: Genetic analysis, GH stimulation, rhGH treatme...

Hypogonadotropic Hypogonadism in a Girl with 2p11.2–2q12.1 Duplication

Bianconi Martina , Scalini Perla , Maccora Ilaria , de Martino Maurizio , Megna Paolo , Stagi Stefano

Background: Patients with chromosome 2 pericentromeric duplication are rarely reported in literature.Objective and hypotheses: To describe a young girl with a congenital malformations syndrome, hypogonadotropic hypogonadism and impaired bone quality associated with a chromosome 2 pericentromeric duplication.Results: The proposita was born at 37th weeks of gestation from a twin pregnancy with a cesarean delivery presenting low birth...

The Experience of GAIA (Abuse Childhood and Adolescence Group) – AOU Meyer

Losi Stefania , Anzilotti Giulia , Scalini Perla , De Martino Maurizio , Stagi Stefano

Background: GAIA is a health service of Meyer Children Hospital composed of a multidisciplinary team specialized in the management of children victims of child abuse. Sexual abuse occurs when a child is engaged in sexual activities that cannot comprehend, for which the child is developmentally unprepared and cannot give consent, and/or that violate the law or social taboos of society. The sexual activities may include all forms of oral-genital, genital, or anal contact by or t...

Adiponectin and IL-6 in Simple Childhood Obesity with and without Hepatic Steatosis

Stagi Stefano , Nanni Laura , Scalini Perla , Luisa Vetrano Maria , Mirri Silvia , de Martino Maurizio , Seminara Salvatore

Background: Non-alcoholic fatty liver disease (NAFLD) represents a spectrum of clinicopathological conditions frequently discovered in obese patients and characterized by multifactorial pathogenesis. Hypoadiponectinaemia and higher interleukin (IL)-6 levels has been related to NAFLD, even if some contradictory findings have emphasized our incomplete understanding of the role of the cytokines in NAFLD.Objective and hypotheses: To investigate the relations...

A Case of GH Deficiency in a Female with 3M Syndrome

Bortone Barbara , Scalini Perla , de Martino Maurizio , Giglio Sabrina , Lapi Elisabetta , della Monica Matteo , Stagi Stefano

Background: 3-M syndrome is an autosomal recessive primordial growth disorder characterized by severe prenatal and postnatal growth retardation, normal mental development, unusual facial features and skeletal abnormalities. Mutations in the CUL7, OBSL1 and CCDC8 genes are responsible for this syndrome. In literature a modest response to GH treatment in 3M children is reported without a significant improvement in the final height, suggesting a picture...

Central Precocious Puberty in a Female with Gonadal Dysgenesis and Bilateral Gonadoblastoma

Megna Paolo , Scalini Perla , Capirchio Laura , De Martino Maurizio , Losi Stefania , Stagi Stefano

Background: Gonadal dysgenesis may be rarely associated with precocious puberty (PP) and development of gonadoblastoma. In these patients cases of peripheral PP have been reported. On the contrary, a central PP has been very rarely described.Objective and hypotheses: To describe a female with central PP associated with a bilateral gonadoblastoma.Results: A 8 year and 5 month old phenotypically female child, presenting suspected PP ...

An Unusual Association between Empty Sella and Central Precocious Puberty

Anzilotti Giulia , Losi Stefania , Bencini Erica , Scalini Perla , de Martino Maurizio , Stagi Stefano

Background: Empty sella refers to the radiographic appearance of an enlarged or deformed sella turcica and it is considered a rare occurrence in childhood. Many reports have suggested that it is associated with hypothalamic-pituitary dysfunction, with a high prevalence of growth hormone deficiency, as well as multiple pituitary hormone deficiency, idiopathic delayed puberty and isolated diabetes insipidus.Objective and hypotheses: We describe the case of...
