Background/Aims: Cryptorchidism or undescended testis is a prevalent congenital urogenital condition affecting male newborns with an incidence rate ranging from 1.0 to 4.6%. Mouse models have implicated INSL3 and its receptor RXFP2 (formerly known as GREAT or LGR8) in the development of the condition. RXFP2 acts as a G protein-coupled receptor that triggers the generation of cAMP by binding INSL3. But despite the established role in testicular descent, so far ...

Alterations in resting-state functional connectivity in patients with congenital adrenal hyperplasia

Messina Valeria , van´t Westeinde Annelies , Padilla Nelly , Lajic Svetlana ,

Background: Patients with congenital adrenal hyperplasia (CAH) are treated with life-long glucocorticoid (GC) replacement therapy. Negative effects on cognition, brain structure and function during working memory tasks have been identified. To date, no studies on functional connectivity during rest have been performed in patients with CAH. One study conducted on patients with Cushing’s syndrome, another disorder of cortisol imbalance, suggests that long-t...

Background/ Aim: Over the past 6 years, the IGF1/ IGFBP3 generation test (IGFGT) has been used in Belgium in a standardized form to identify children with severe primary IGF1 deficiency (SPIGFD). In this study, the discordance of the IGF1 and IGFBP3 responses during an IGFGT and the prevalence of SPIGFD were analyzed in a cohort of children with short stature (height SDS < - 2) and presenting with low (below lower reference limit) serum IGF1 level and norma...

Avascular necrosis of the hip as a rare complication of growth hormone therapy

van der Linde Annelieke , van Baelen Amber , van Bergen Christiaan

Background: Growth hormone therapy can be indicated for children who are born small for gestation age (SGA) (either birth weight or birth height < -2 SDS) without catch-up growth (height < -2.5 SDS) at age 4 years. Growth hormone therapy is considered a safe treatment.Case presentation: A 12-year-old girl was referred to the pediatric endocrinologist for short stature. She was born small for gestational age (birth ...

Obesity in ROHHADNET Syndrome: Does Cortisol Play a Role?

van Tellingen Vera , van Trotsenburg Paul

Background: ROHHADNET syndrome is characterised by rapid onset childhood obesity, hypoventilation, variable hypothalamic-pituitary and autonomic dysfunction, and neuroendocrine tumors in 30–40%. Autoimmunity and paraneoplastic syndrome have been proposed as possible pathophysiological mechanisms, but the exact aetiology remains unclear.Objective and hypotheses: We present the clinical course of ROHHADNET syndrome in a 17-year-old girl, with consecut...

Recurrent Ketosis after Prolonged Exercise in Type 1 Diabetes: The Need for Glycogen Replacement Strategies: Case Report

van Albada Mirjam , van Waarde Willie Bakker

Background: In diabetic athletes, glycogen depletion can contribute to the early development of starvation ketones as is demonstrated by our patient.Case presentation: Our patient, a 15-year-old male triathlete with type 1 diabetes for 5 years was referred to our tertiary center because of suboptimal regulation on continuous subcutaneous insulin infusion (CSII). He frequently awoke with nausea and ketosis, which was initially attributed to failure of ins...

Busiah Kanetee , Peet Aleksandr , Tornese Gianluca , Weintrob Naomi , Patel Leena , Hamza Rasha ,

Background: A Europe-wide training program in Paediatric Endocrinology and Diabetes (PED) was initiated by Professor Leo Van den Brande in 1976. PED was recognised as a subspecialty in 1996 by the European Board of Paediatrics (EBP), which is a section of the Union of European Medical Specialists (UEMS). UEMS aims to ensure high standards for training across Europe and the minimum requirements are set out in the European Training Requirements (ETR). The first ...

Central Hypothyroidism – an Update

van Trotsenburg Paul

Central hypothyroidism can be best defined as lower than desirable thyroid hormone production and secretion because of insufficient stimulation of a normal thyroid gland by a defective pituitary or hypothalamus, resulting in a too low plasma or serum (free) thyroxine (FT4) concentration accompanied by a more or less normal thyrotropin (TSH) concentration. Central hypothyroidism can occur isolated or as part of multiple pituitary hormone deficiency and can be a congenital or ac...
