Neonatal reference intervals for serum steroid hormone concentrations measured by LC-MS/MS.

Objectives: Congenital adrenal hyperplasia (CAH) is a rare, inherited disorder of adrenal steroid synthesis. In many countries it is part of the neonatal screening program enabling early diagnosis and treatment. In case of an abnormal neonatal screening result or when other differences of sexual development (DSD) are suspected, measurement of serum steroid hormones using liquid chromatography coupled to mass spectrometry (LC-MS/MS) is needed for further diagnosis.

Pediatric Graves' orbitopathy: a multicentre study.

Purpose: Graves' orbitopathy (GO) is a rare condition in children often considered to be a less severe condition than at an older age. The aim of our study was to analyse if there are any factors that distinguish paediatric from adult GO in order to provide guidelines for assessing and managing paediatric GO.

Methods: Study design is a multicentre retrospective observational case series; 115 paediatric patients diagnosed with GO who visited our university medical centres in the Netherlands and Iran between 2003 and 2019 were submitted for complete ophthalmological examinations, serological testing and/or orbital imaging.

Hypothalamic obesity after treatment for craniopharyngioma: the importance of the home environment.

Hypothalamic obesity after treatment for craniopharyngioma is a well-recognized, severe problem. Treatment of hypothalamic obesity is difficult and often frustrating for the patient, the parents and the professional care-giver. Because hypothalamic obesity is caused by an underlying medical disorder, it is often assumed that regular diet and exercise are not beneficial to reduce the extraordinarily high body mass index, and in fact, lifestyle interventions have been shown to be insufficient in case of extreme hypothalamic obesity.
