Background: Fibroblast growth factor 21 (FGF-21) is a complex molecule involved in lipid and glucose metabolism. FGF-21 shares biochemical pathways and sites of action with thyroid hormones. Current data correlate FGF-21 levels to thyroid function. The aim of the present study was to investigate possible associations among FGF-21 levels, resting metabolic rate (RMR), lipidemic profile and L-thyroxin replacement therapy treatment in children and adolescents wit...

Kiewert Cordula , Jedanowski Julia , P. Hauffa Berthold , Petersenn Stephan , Führer Dagmar , Unger Nicole

Introduction: Transition medicine aims at the coordinated transfer of young patients with a chronic disease from paediatric to adult specialist care. The present study reflects 20 years of experience in transitioning patients with congenital adrenal hyperplasia (CAH) in a single centre university setting.Methods: The endocrine transition clinic was established in 2002 and offers joint consultations with a paediatric and ...

Do perinatal history and mode of delivery affect age at menarche? Preliminary data of girls with Greek origin

Tsinopoulou Vasiliki-Rengina , P. Kotanidou Eleni , Bacopoulou Flora , Fidani Liana , Galli-Tsinopoulou Assimina , Christoforidis Athanasios

Objectives: Age at menarche depends on genetic, environmental, epigenetic and other factors. Studies have shown that aspects of perinatal history, including birth weight, mode of delivery (caesarian section or vaginal delivery) and gestational week at birth influence the onset of puberty. The purpose of this study was to record the age at menarche in a sample of Greek girls and to correlate it with their perinatal history, the mothers’ age at menarche, t...

46 XY Gonadal Dysgenesis- Transmission of a Maternal Mosaic Novel DMRT1 Mutation

C Kennedy Elaine , Ann Lynch Sally , Deegan Nikita , J Redmond Elaine , P Hawkes Colin

We present the case of a 15-year-old girl who presented with primary amenorrhoea. On examination she had absent pubertal development (Tanner Stage B1), with a normal-appearing external vagina and vaginal opening. Investigations demonstrated elevated gonadotropins, concerning for primary gonadal failure. Pelvic ultrasound and MRI demonstrated the presence of a rudimentary uterus and the absence of visible gonads. Karyotype confirmed 46 XY. Trio exome sequencing identified a mis...

At present no European recommendations for the management of pediatric thyroid nodules and differentiated thyroid carcinoma (DTC) exist. Differences in clinical, molecular, and pathological characteristics between pediatric and adult DTC emphasize the need for specific recommendations for the pediatric population. An expert panel was instituted by the executive committee of the European Thyroid Association (ETA) including an international community of experts from a variety of...

"Girls with Idiopathic Premature Adrenarche Achieve Normal Adult Height"

Javier Mejorado-Molano Franciso , Pérez-Segura Pilar , Gómez-Aragón Isabel , Collado-Valiente Rosa , Gómez-Neo Ana , Gavela-Pérez Teresa , Soriano-Guillén Leandro

Introduction: Studies about pubertal onset and the menarcheal age in girls with the antecedent of idiopathic premature adrenarche (IPA) are limited and with discordant results. For these reasons, we created a cohort of girls with the diagnosis of IPA. The objectives of our study were: a) to know the age of pubertal onset; b) to evaluate menarcheal age; c) to determine the growth rate in the first two years after the IPA diagnosis; d) to collect adult height da...

Emerging phenotypes linked to variants in SAMD9 and MIRAGE syndrome

P. Suntharalingham Jenifer , Ishida Miho , E. Stalman Susanne , Solanky Nita , E. Moore Gudrun , C. Achermann John , Buonocore Federica

Background: Heterozygous de novo variants in SAMD9 cause the complex multisystem growth disorder, MIRAGE syndrome. Core features are myelodysplasia, infection, restricted growth, adrenal hypoplasia, genital/gonadal phenotypes, and enteropathy. However, the range of additional associations is expanding and includes disrupted placental development, poor post-natal growth, and other endocrine features. Milder phenotypes are also described, such ...

FADES: A Birth Cohort to Understand the Mechanisms Underlying Accelerated Onset of Autoimmunity in Children with Down's Syndrome

Williams Georgina , Mortimer Georgina L. , Leary Sam D. , Williams Alistair J.K. , Gillespie Kathleen M. , Hamilton - Shield Julian P.

Background and Aims: Children with Down's syndrome (DS) are at increased risk of autoimmune conditions including type 1 diabetes (T1D), coeliac and thyroid disease. We previously examined the clinical and immunogenetic characteristics of these conditions in children with DS. An earlier age-of-onset of diabetes was observed compared with children with T1D from the general population despite having decreased frequencies of the established genetic susceptibil...

Long-Term Honeymoon Period in Type 1 Diabetes: True Diagnosis MODY5; New Mutation of HNF1B

Bideci Aysun , Küpçü Zekiye , Döğer Esra , Çamurdan Orhun , Cinaz Peyami

Introduction: MODY is an autosomal dominant inherited type of diabetes that has been diagnosed before the age of 25 and caused by pancreatic β-cell dysfunction. HNF1B-MODY is more rare than other MODY causes and its frequency is between 1-5%. Mutations in HNF1B (MODY 5) are associated with pancreatic agenesis, kidney anomalies, genital system malformations and liver dysfunction.Case: The patient is 8 years 2 ...

EAP1 Mutations Cause an Impaired Transcriptional Activity on GnRH Promoter that Leads to Self-Limited Delayed Puberty

Mancini Alessandra , Howard Sasha R , Cabrera Claudia P , Barnes Michael R , Heger Sabine , Guasti Leonardo , Ojeda Sergio , Dunkel Leo

Background: The initiation of puberty is orchestrated by the augmentation in the secretion of gonadotropin-releasing hormone (GnRH) from a few thousand neurons located in the hypothalamus. Recent findings identified that the neuroendocrine control of puberty is regulated by a network of transcriptional factors hierarchically organized, but this still remains not fully elucidated. Enhanced At Puberty 1 (EAP1) is one of the main regulators of pubertal onset and it is ex...
