Management of Central Hypothyroidism

van Trotsenburg P

Central hypothyroidism (CeH) can be defined as a lower than desirable secretion of thyroid hormone by a normal thyroid gland resulting from (quantitative or qualitative) insufficient TSH secretion. Causes are congenital and acquired functional or anatomic defects of the hypothalamus, pituitary gland or both. CeH can be difficult to diagnose, especially in children without a history of brain defects or brain damaging treatment (e.g. irradiation), and when plasma FT4 concentrati...

Motor Performance in Turner Syndrome

van Alfen Janielle

The aim of this presentation is to give an overview of motor disabilities in girls with Turner syndrome (TS), the impact on daily life and suggestions for treatment.Girls with TS show substantially lower performance in gross and fine motor function tests and motor milestones are achieved relatively late. Moreover, girls with TS frequently encounter problems in specific motor functioning i.e. oral-motor and visual-motor coordination, motor learning and pr...

Use of Urinary Gonadotropins for The Evaluation of the Minipubertal Profile in Term Newborns and Infants Within The First Six Months of Age

Lucaccioni Laura , Trevisani Viola , Passini Erica , Palandri Lucia , Bruzzi Patrizia , Predieri Barbara , Righi Elena , Iughetti Lorenzo

Background: The activation of the hypothalamus-pituitary-gonadal (HPG) axis during the first months both in males(M) and females(F) is named as minipuberty. Urinary gonadotropins (uGn) represent an unexpensive and non-invasive method of assessing pubertal development and they have recently been used also for studying minipuberty.Aims of the study are: 1) to describe the urinary hormonal pattern (uLH, uFSH, testosterone – uT, oestra...

Effect of Very Early Growth Hormone (GH) Treatment on Long-term Growth in Girls with Turner Syndrome (TS): A Multicenter, Open-Label, Extension Study

Davenport Marsha , Fechner Patricia , Ross Judith , Eugster Erica , Jia Nan , Patel Hiren , Zagar Anthony , Quigley Charmian

Background: Late initiation of GH results in suboptimal adult height for many women with TS. In a landmark, randomized, controlled, clinical trial (“Toddler Turner” study) we showed that 2 y of early GH (ET group) started at 1.98±1.01 y, resulted in height SDS difference of 1.6±0.6 SDS vs. early untreated group (EUT).Objective and hypotheses: It was unclear if early height gains would result in taller adult heights, so patients were f...

Can we Standardize Sex Assignment in 45,X/46,XY Mixed Gonadal Dysgenesis?

Colindres Johanna Viau , Eugster Erica , Smith O'Brian , Gunn Sheila , Mendiratta Meenal , Karaviti Lefkothea

Background: Patients with 45,X/46,XY mixed gonadal dysgenesis (MGD) have variable phenotypes leading to both male and female sex assignments. A multidisciplinary team should guide the process of sex assignment, however a standardized approach may provide objective guidance for the team as well as a tool for settings without such resources. One of the most important considerations for sex assignment is the hormonal production, which often determines the degree of virilization. ...

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...

A patient with multi-locus imprinting disturbance and 46, XY hypovirilization

Ulgiati Fiorenza , Boros Erica , Vicinanza Alfredo , Driessens Natacha , Netchine Irene , Brachet Cécile , Heinrichs Claudine

Hypomethylation of the ICR1 in 11p15 is the epigenetic alteration causing Silver Russel Syndrome (SRS) in over 50% of the patients. It is reported that 7-38% of SRS patients have multi-locus imprinting disturbance (MLID). MLID has been suggested to result from maternal mutations affecting the acquisition or maintenance of imprints. We report on a patient with MLID who presented with features of SRS and Temple syndrome in addition to severe 46 XY hypovirilisation, pseudohypopar...

Meta-analysis of DNA methylation datasets identifies aberrant DNA methylation of thyroid function and development genes in Down syndrome

Lauffer Peter , Zwaveling-Soonawala Nitash , Li Shaobo , Bacalini Maria , Naumova Oxana , Wiemels Joseph , Boelen Anita , Henneman Peter , de Smith Adam , van Trotsenburg Paul

Down syndrome (DS) is characterized by a higher incidence of congenital hypothyroidism (CH) and a high prevalence of subclinical hypothyroidism (SH) early in life. Children and adults with DS have an increased risk of developing autoimmune thyroid disease, however CH and early SH cannot be explained by thyroid autoimmunity. The etiology of CH and early SH in DS remains to be elucidated. Considering the recently discovered genome-wide transcriptional and epigenetic alterations ...

Testicular Adrenal Rest Tumors (TARTs) as presenting symptom of CAH due to CYP11A1deficiency.

Bakker-van Waarde Willie , Claahsen-van der Grinten Hedi

Background: TARTs mostly occur in congenital adrenal hyperplasia due to 21-hydroxylase deficiency, but were described in other forms of CAH. Elevated ACTH levels, may play a role in TARTs development. Here we describe the first child with undetected CYP11A1 deficiency who presented with TART.Case description: An 11 year old boy noticed left sided scrotal enlargement, without further complaints. Ultrasound showed a hydroc...

Gonadal Function in Congenital Adrenal Hyperplasia (CAH)

Claahsen - van der Grinten Hedi

Congenital adrenal hyperplasia (CAH) is a group of rare congenital disorders of the adrenal cortex due to a defect in one of the enzymes involved in steroid synthesis leading to cortisol deficiency and overproduction of adrenal androgens. In the most severe forms CAH is a life threatening disease due to the risk of Addisonian and salt wasting crisis. In the last 50 years diagnostics and treatment improved significantly. Patients are treated with lifelong replacement of glucoco...
