Evaluation of new cutt-off points of the LHRH stimulation test in the diagnosis of central precocious puberty

Valls Llussà Aina , Murillo Vallés Marta , Martinez Couselo Silvia , Sol Ventura Paula

Introduction: Central precocious puberty (PPC) is defined by the appearance of sexual characters at a chronological age lower than -2.5DS of the average for the reference population. Diagnostic is clinical but the hormonal assessment is essential. Basal gonadotropin values are not enough for the diagnosis. Gonadotropin-releasing hormone (GnRH) stimulation tests evidence the activation of the hypothalamic-pituitary-gonadal axis, however there is controversy abo...

Novel genetic variant in NR5A1 (SF1) gene with clinical presentation of Hypergonadotropic hypogonadism

Sredkova-Ruskova Maria , Andonova Silvia , Ruskov Todor , Veleva Tsvetina , Delchev Trayan , Savov Alexey , Avdjieva-Tzavella Daniela

Background/Objectives: Hypergonadotropic hypogonadism (HH) is characterised by primary gonadal failure with excess of pituitary gonadotropin secretion. The causes can be congenital or acquired. Herein, we report a case of a 10-years-old-boy with obesity, development of HH during follow-up and a novel genetic variant in NR5A1 (SF1) gene with de novo origin.Methods: The child presented with obesity (started at the age of 5...

Agreement between Acth-low test and Insuline Tolerance Test in Patients with Risk Factors for Central Adrenal Insufficiency

Panciroli Marta , Angelelli Alessia , Fava Daniela , Patti Giuseppa , Napoli Flavia , Di Iorgi Natascia , Maghnie Mohamad

Background: Central adrenal insufficiency(CAI) is a potential life-threatening condition and a prompt diagnosis represents a clinical challenge; indeed, the Insulin Tolerance Test(ITT), gold standard for CAI diagnosis, can be contraindicated in some conditions. Aims were to evaluate the diagnostic value of the ACTH low test(ACTH-LT) compared to the ITT and to identify eventual determinants(primary diagnosis, risk factors, symptoms, baseline cortisol, hypothala...

Adult Height is impaired in females with Medulloblastoma and hypogonadism: Impact of Pubertal Timing

Ferraro Paola , Casalini Emilio , Fava Daniela , Maghnie Mohamad , Patti Giuseppa , Di Iorgi Natascia

Introduction and Aim of the Study: girls with previous pediatric medulloblastoma (MB) are at risk of short stature and impairment of the hypothalamic pituitary gonadal function due to multiple risk factors;our aim was to assess the impact of hypergonadotropic hypogonadism (HH) on growth up to final height (FH) in females with or without growth hormone deficiency (GHD).Methods: anthropometrics (height-Ht-SDS, BMI-SDS, Tan...

Congenital hypogonadotropic hypogonadism caused by a novel mutation of GnRHR gene: a case report

Cristina Maggio Maria , Venezia Renato , Maria Di Blasio Anna , Corsello Giovanni

Hypogonadotropic hypogonadism is characterized by low levels of gonadotropins and delayed or absent sexual development. Most of the patients reach the diagnosis in late adolescence or in adulthood. A timely, appropriate diagnosis implicates a better clinical outcome and treatment timing. We describe the clinical case of a 15-year-old girl with primary amenorrhea. Stature and weight were in accordance with mid parental height; Tanner stage: PH2 B1. FSH, LH, oestradiol showed pr...

Association Between Adiposity Measures and Metabolic Variables in Children and Adolescentswith Obesity

Umano Giuseppina Rosaria , Di Sessa Anna , Cirillo Grazia , Ursi Davide , Marzuillo Pierluigi , Miraglia Del Giudice Emanuele

Childhood obesity has become a major health issue in the last decades. Moreover, identifying a simple, feasible, and valid screening tool to select subjects at higher risk for obesity-related comorbidities has become a challenge. Current guidelines reccommend to use BMI percentile for overweight and obesity diagnosis. However, waist-to-height ratio (WHR) has been associated with the risk of metabolic derangement in children and adolescents with overweight and obesity. In addit...

An Impaired Lipid Profile is a Sign of Reduced Insulin Sensitivity in Children and Adolescents at Type 1 Diabetes Onset

Maltoni Giulio , Zucchini Stefano , Zioutas Maximiliano , Di Natale Valeria , Cassio Alessandra

At type 1 diabetes (T1D) onset, international guidelines reccommend a starting subcutaneous insulin dose widely ranging from 0,5 to 1 u/kg/day. In fact, many factors such as age, pubertal stage and the severity of ketoacidosis, may influence insulin sensitivity. However, it is a common experience that many subjects may require a higher insulin daily dose than expected, with the subsequent need of longer time to achieve stable blood glucose values and the extension of days of h...

High Incidence of Cranial Synostosis and Chiari Malformation in Children with X-linked Hypophosphatemic Rickets

Rothenbuhler Anya , Bacchetta Justine , Fadel Nathalie , Lambert Anne Sophie , Adamsbaum Catherine , Linglart Agnes , Rocco Federicco Di

Background: X-linked hypophosphatemic rickets (XLH) represents the most common form of hypophosphatemia and leads to vitamin D resistant rickets in children. Even though cranial vault and craniovertebral anomalies of potential neurosurgical interest, namely early closure of the cranial sutures and Chiari type I malformation- have been observed in XLH patients their actual incidence is not established.Aim: Describe and analyze the incidence of cranial and...

Early Menarche is Associated with Insulin Resistance and Non-Alcoholic Fatty Liver Disease in Obese Adolescents

Di Sessa Anna , Grandone Anna , Marzuillo Pierluigi , Miraglia del Giudice Emanuele

Background: Menarche is a significant event in the reproductive life of a woman and represents the late event in puberty indicating that a sexually immature child has become reproductively capable. Even though the timing of puberty onset is approximately conserved in different populations, the puberty starts across a wide range of ages in normal girls. However, in the last decades we are observing that girls are experiencing earlier breast development and earlier menarche, als...
