Background: Determination of steroids in amniotic fluid (AF; Forest et al., J Clin Endocrinol Metab, 1980) has been essentially used in the three past decades for the prenatal diagnosis of 21-OH deficiency. With the recent advances of ultrasound technology (US) and the widespread use of amniocentesis, prenatal diagnosis of DSD appears more common especially if a mismatch between karyotype and external genitalia detected by US occurs. An accurate and specific ...

Background: The response to ACTH test (synacthen®) is a very useful for the screening of steroidogenesis enzymatic deficiency. With the development of steroid quantification by LC-MSMS more specific than most of immunoassays, the determination of reference value is required at basal and under stimulation time.Objective and hypotheses:: The aim of this study is the determination in the same extraction and chromatography after Synacthen references val...

Background: Treatment of congenital primary hypothyroidism (CPHT) fluctuates between two opposite risks for the neuro-cognitive development in a critical window during the neonatal period, under- and over-treatment.Objective: To investigate the relevance of current international recommendations of 10–15 μg/kg per day for L-thyroxine (lT4) doses in CPHT.Method: fT4 and TSH were measured...

Context: Transgender adolescents can be treated with puberty suppression (PS) using GnRH agonists (GnRHa), and subsequent hormone therapy (HT). Up to this date, it has not been described at what rate body composition in transgender adolescents changes during the first years of treatment. Also, it is unknown whether Tanner stage at which treatment is initiated, might affect this treatment outcome.Methods: Transgender adol...

Introduction: Little is known about the effects of puberty suppression (PS) and hormone therapy (HT) on growth and adult height in transgender adolescents. These are topics of interest since height differs between sexes and some transgirls wish to limit their growth. In this longitudinal cohort study, we investigated the influence of PS and HT on growth and the efficacy of growth reduction therapy in transgender girls.Methods:</s...

Context: For transgender women undergoing gender-affirming hormone therapy (HT), breast development is an important treatment outcome. Since earlier studies showed small breast volumes in trans women treated with HT, we hypothesized that testosterone exposure during puberty might negatively influence breast development and that early initiation of puberty suppression (PS) might have a positive effect on breast development.Aim:</s...

Aims: The TEENs study is an international, cross-sectional observational study aiming to assess type 1 diabetes (T1D) management and psychosocial parameters in children, adolescents, and young adults, to identify approaches to optimise glycaemic control and outcomes. Results from 11 European countries are presented.Methods: 111 centres providing diabetes care to young T1D patients collected data by participant interview, medical record review and partici...

Vitamin D supplementation is recommended for breastfed infants as primary prevention of vitamin D deficiency and nutritional rickets. Globally, the most commonly recommended dosage of vitamin D is 400 IU/day for healthy breastfed infants. Whether there are benefits of higher dosages of vitamin D to infant bone mass and body composition has been investigated. The objective of this presentation is to review the evidence from randomized controlled trials conducted in healthy term...

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...

Background: Diagnosis of congenital adrenal hyperplasia (CAH) is delayed in developing countries and children are long exposed to high levels of androgens. These androgens have deleterious effect on heart.Objective and hypotheses: Evaluate cardiac function of children followed for CAH and compared it to a group of healthy children.Method: We carried out a case-control study, 1 case for 2 controls matched for age and genotypic sex, ...
