Methodological considerations on determining sex steroids in children: Comparison of conventional immunoassays with LC-MS/MS

Ankarberg Lindgren Carina , Becker Charlotte , Svala Emilia , Ryberg Henrik

Objectives: In laboratory medicine, external quality assessment (EQA) schemes have become versatile tools for the detection of analytical flaws. However, for pediatric sex steroid levels EQA schemes are lacking. We aimed to investigate the suitability of different estradiol and testosterone immunoassays in a pediatric setting, in comparison with clinical liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays.Methods:</s...

An Unusual Testicular Adrenal Rest Tumor localization in a 15-Year-Old Boy with Congenital Adrenal Hyperplasia

Corica Domenico , Aversa Tommaso , Bottari Antonio , Ascenti Giorgio , Wasniewska Malgorzata

Introduction: Testicular adrenal rest tumor (TART) is the most important cause of infertility in male with congenital adrenal hyperplasia (CAH). TART is a benign tumor, mainly bilateral (75-80%), usually diagnosed in under-treated CAH male with hypercorticotropinemia, which generally regresses after glucocorticoids therapy adjustment. However, it may determine an irreversible damage by compression and toxic-paracrine effects on the surrounding testicular t...

Pituitary Hyperplasia as a Complication of Severe Hypothyroidism due to Hashimoto's Thyroiditis Could Impair Pituitary Function

Corica Domenico , Granata Francesca , Galletta Karol , Wasniewska Malgorzata

Introduction: Long-standing primary hypothyroidism is an unusual cause of pituitary hyperplasia (PH) in children, sometimes difficult to distinguish on CT or MRI from primary pituitary tumors. Loss of thyroxine feedback determines overproduction of thyrotropin releasing hormone (TRH) and subsequent TSH-releasing cells hyperplasia in the anterior pituitary. Levothyroxine replacement therapy has been shown to usually determine regression of PH.<p class="abst...

Impact of Puberty on Final Height in Children and Adolescents with Congenital Adrenal Hyperplasia (CAH)

Rohayem Julia , Schreiner Felix , Riedl Stefan , Voss Egbert , Wolf Johannes , Grasemann Corinna , Fink Katharina , Mohnicke Klaus

Introduction: An optimized replacement regimen with glucocorticoids and mineralocorticoids in subjects with congenital adrenal hyperplasia (CAH) aims at preventing life-threatening salt wasting and adrenal crises, virilization and pubertal precocity, and at enabling normal linear growth.Aims: We investigated puberty and its impact on final height in children and adolescents with CAH.Patients and Methods: In a cohort of post-pubesce...

Pseudopubertas Praecox in a 4 Year Old Boy with Bilateral Atypical Adrenocortical Adenomas

Brichta Corinna , Wurm Michael , Hodde Franka , van der Werf-Grohmann Natascha , Schwab Karl Otfried

Introduction: Adrenocortical tumors are very rare in children, with a prevalence of just 0.3 cases/million/year. Autonomic hormone production by adrenal cortical tumors may cause peripheral precocious puberty.Case report: A 4-year-old boy was presented by his parents because of pubertal behavior with aggressive features and a significant increase in the size of the penis. The parents also noticed a strong growth spurt and sweat odor. The boy had a good g...

No Relationship Between Thyroid Function and ADHD – Results From a Nationwide Prospective Epidemiological Study and Mendelian Randomization

Hirtz Raphael , Grasemann Corinna , Dinkelbach Lars , Hinney Anke , Hebebrand Johannes , Peters Triinu

Introduction: Limited research has focused on the potential connection between thyroid function and attention-deficit/hyperactivity disorder (ADHD), particularly beyond prenatal effects. The few studies addressing children and adolescents have important methodological shortcomings, mainly when seeking to establish causality. To clarify this relationship, a combined epidemiological and genetic approach was adopted to overcome the methodological limitations of e...

Prader Willi Syndrome with Cribiform Papillary Thyroid Carcinoma. A case to share

López Avellaneda Carina , Guntsche Zelmira , José Guillamondegui María , Oliva Julio , Breyer Federico

Cribiform Papillary Thyroid Carcinoma has low prevalence. Our objective is to present a case and to emphasize future implications. We present a female 14.9 years old patient with PWS (del 15 q11-13 by methylation test) with a history of asthma, hepatic steatosis, increased Waist-to-Height ratio, HbA1c 5.86 % and C-Peptide 3.64 ng/mL. She had primary hypotiroidism since 7 years old treated with 25 mg/ day of levothyroxine and impaired fasting glucose since 10 years old with a B...

Sustainability of Estradiol Drug Concentrations in Cut Matrix Patches; A Study of Different Brands with Potential Use for Pubertal Induction

Ankarberg-Lindgren Carina , Gawlik Aneta , Kristrom Berit , Mazzanti Laura , Sas Theo CJ

Background: The estimated estradiol (E2) dose required for pubertal induction in hypogonadal girls is about 1/10 of the adult dose. Previous studies have shown that it is possible to provide an individualized and physiological dose for pubertal induction by cutting the patch into smaller pieces. However, the manufacturers do not guarantee stability or utility of cut E2 patches, primarily designed for postmenopausal women, and have no interest in that eval...

Normalization of Puberty and Adult Height in Girls with Turner Syndrome, Randomised Trials vs Age and Dose at GH-Start

Kristrom Berit , Ankarberg-Lindgren Carina , Barrenas Marie-Louise , Nilsson Karlolof , Albertsson-Wikland Kerstin

Background: Early TS diagnosis permits early GH start and estradiol (E2) supplementation approaching adult height (AH) at normal age and within a normal range. However, higher age at diagnosis is still a challenge.Objective and hypotheses: The hypothesis from our long-term trials will result in knowledge for personalized treatment in order to obtain a psychological acceptable age at onset of puberty and still an attained AH within normal range...

Longitudinal Changes During Prepubertal Years in Visceral Fat and Steroid Hormones – SGA vs AGA Children

Ankarberg-Lindgren Carina , Andersson Mats X , Karlsson Ann-Katrine , Dahlgren Jovanna

Background: Small for gestational age (SGA) children have reportedly increased DHEAS levels during prepubertal years. However, steroid hormones have not been followed longitudinally in a healthy population compared to body composition.Aims and objectives: To evaluate steroid hormone patterns in prepubertal children correlated to visceral fat measures.Methods: Body composition was investigated with magnetic resonance (MR) of truncal...
