Background: Congenital hyperinsulinism (CHI) causes severe hypoglycaemia in children. Diazoxide and daily octreotide injections are first and second-line of treatment for CHI respectively. Diazoxide can cause severe hypertrichosis resulting in parental anxiety and compliance issues.Objective and hypotheses: To evaluate the efficacy, safety and pharmacokinetics of Lanreotide therapy in CHI patients.Method: Patients >6 months of ...

Background: Hypospadias affects approximately 1/200 newborn males. Based on the testicular dysgenesis syndrome hypothesis, some may be suspected of having persistent testicular dysfunction later in life. Few clinical data currently support this hypothesis.Methods: Cross-sectional assessment of hypospadias cases (n = 193) and controls (n = 50), aged 16-21 years, recruited at Ghent University Hospital and...

Background: Bilateral testicular regression (BTR) is characterized by the absence of both testicles in a newborn male or shortly thereafter, and presenting as bilateral cryptorchidism with undetectable AMH levels and the absence of Müllerian structures on pelvic ultrasound. Depending on when the regression occurs during fetal development, the condition can be associated with a micropenis. Few studies have explored the etiology and long-term outcome of BTR...

Background: The COVID-19 crisis required paediatric endocrinologists to rapidly adopt telehealth into their clinical practice. Accurate auxology is a cornerstone of paediatric endocrinology care and is needed to monitor growth and guide medication changes. Remote consultations depend upon parent-reported measurements. However, home height measurements are often inaccurate.Aim: We designed a quality improvement study with...

Background: Counselling adolescents with chronic diseases can be challenging when it comes to appropriate interview techniques and the doctor's attitude towards the patient. Successful communication can be a key element of treatment. Motivational interviewing (MI) is widely applicable in the management of behavioural problems and illnesses, as it increases patients' motivation for lifestyle changes. This plays a particularly important role in the tre...

Introduction: Congenital adrenal hyperplasia (CAH) is an autosomal recessively transmitted disease and 95% of CAH cases are due to 21-hydroxylase deficiency (21-OHD). There are more than 100 mutations that cause CAH due to 21-OHD and the clinical expression of the disease is reported to correlate with mutated alleles.The aim: The aim of this study was to investigate responsible mutations and then to evaluate genotype...

The calcium-sensing receptor (CaSR) is the master regulator of calcium homeostasis. This class C G-protein coupled receptor binds extracellular calcium and phosphate, and is the target of calcimimetic and calcilytic drugs. The CaSR is expressed on the cell surface as a homodimer and is most highly expressed in the parathyroid glands and the renal thick ascending limb, where it acts to maintain a near-constancy of plasma calcium concentrations by regulating parathyroid hormone ...

Iodine is the most important element in thyroid function. Its deficiency and excess can cause hypothyroidism. Our location has been known as the iodine deficiency area for the last 20 years. In this study, we aimed to investigate thyroid dysfunction and assess its relationship with iodine levels in the neonatal period.Method: One hundred and seventy newborns were included in the study. Infants were selected from patients referred to for ...

Background: Hetero- and homozygous mutations in Steroidogenic Factor1 (SF1, NR5A1) cause 46,XY and 46,XX disorders of sex development (DSD), azoospermia, and primary ovarian insufficiency. NR5A1 is also involved in embryonic spleen development, by transactivation of T-cell Leukemia Homeobox 1 (TLX1). Hypo- or asplenism have occasionally been observed in DSD patients with NR5A1 mutations.<p clas...

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 ...
