Background and Aims: Coats plus syndrome (MIM # 612199) is a highly pleiotropic disorder particularly affecting brain, eye, bone and gastrointestinal tract. We describe the phenotype of a patient with severe growth failure where whole exome sequencing (WES) revealed compound heterozygosity for two mutations in the CTC1 gene.Patient and Methods: The patient, the fourth child of healthy non-consanguineous parents, was born...

Congenital Hyperinsulinism (HI) causes severe hypoglycemia. In most countries, the estimated incidence of HI is approximately 1/25,000 to 1/50,000 births, classifying it as a rare disease. According to Pediatric Endocrine Society (PES) Guidelines, neonates should be screened for hypoglycemia if they have any of the following: symptoms of hypoglycemia, large for gestational age, perinatal stress, premature or postmature delivery, infant of diabetic mother, family history of a g...

Background: MODY is characterised by an early onset of diabetes and a positive family history of diabetes with an autosomal dominant mode of inheritance. We report a 15 year girl with a HNF1A mutation who presented with MODY without a positive family history.Objective and hypotheses: HNF1A-MODY is often misdiagnosed as type 1 or type 2 diabetes. Genetic confirmation of MODY in insulin-treated patients helps in making changes in the treatment modality as ...

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: A combination of GH and a GnRH agonist is sometimes used to improve adult height in children with a poor height prediction, only few studies support this.Study design: In this multicenter study, 24 short girls in early puberty, with a bone age below 12.0 years, an adult height prediction below 151.0 cm and normal body proportions were treated with GH (Zomacton) transjections 50 μg/kg per day and triptorelin (Decapeptyl) i.m. (3.75 mg/mon...

Background: Haplo-insufficiency of the Myelin-Regulatory Factor (MYRF) gene causes cardiac-urogenital syndrome (CUGS) and Differences in Sexual Development (DSD) in 46,XY and 46,XX (OMIM #618280). The gene product, a transcription factor, is involved in development of Coelomic epithelium derived cells, and likely causative for DSD. To date, only a few MYRF de novo variants are reported in children with DSD and associated CUGS symptoms.<s...

Capillary hyperglycemia in critically ill infants is a situation with numerous interfering factors, from acute illnesses to concomitant use of medications and may or may not be a manifestation of endocrinological urgency. Clinical case: Female patient, 2 months old, with failure to thrive, hepatomegaly without cholestasis, polyuria and compensated metabolic acidosis. On admission, capillary blood glucose levels above 200 mg/dL were measured even without concomitant use of cort...

Title: The making of the EndoWatch: A new device for Early Monitoring of Hypothalamic imbalances. Hulsmann S, Petras S, Fraboulet P, Yuan Lu, van Santen HM (on behalf of the EndoWatch team) Keywords: Paediatric and adolescent cancer survivors, Brain tumour, Quality of Life, Wearable, Hypothalamic Obesity Main goals: Aim for better quality of lifeIntroduction: Children and adults with a suprasellar (hypothalamic)...

Background: SHOX and enhancer regions on PAR1 disorders have variable phenotypic consequences such as idiopathic short stature (ISS) and Leri-Weill Dyschondrosteosis (LWD).Objective and hypotheses: The aim of this observational multicentric study was to describe phenotypes and genotypes of a large population with mutation on SHOX and adjacent regions and to identify a possible phenotype–genotype correlation.M...

Background: Congenital Hyperinsulinism International (CHI) is an international non-profit organization focused on improving the lives of patients and families living with hyperinsulinism (HI). Despite many advances in the care of patients with HI, long term neurologic outcomes have not significantly improved, highlighting the need for CHI’s goals for robust and rapidly translatable research. We describe the development of a collaborative research network...
