Background: Neurocognitive retardation is one of the most important consequences that small for gestational age (SGA) children may suffer although conflicting results have been published.Objective and hypotheses: The aim of this study was to study psychomotor development (PD) in children born SGA during the first two years of life in order to identify children at risk as early as possible.Method: 108 cases borh SGA have been studie...

Background: Hyperinsulinism (HI) due to excess and dysregulated insulin secretion is the most common cause of severe and recurrent hypoglycaemia in childhood. High cerebral glucose utilisation in the early hours results in high risk of hypoglycaemia for people with diabetes and carries a significant risk of brain injury. Prevention of hypoglycaemia is the cornerstone of management for HI but the risk of hypoglycaemia at night or indeed the timing of hypoglycae...

Introduction: Genetic syndromes often show suggestive facial features that provide clues for the diagnosis. Considering the high number of genetic syndromes and the possible overlap of some features, memorizing facial gestalt is a challenging task for clinicians. DeepGestalt technology, and its app Face2Gene, has a growing impact on the diagnosis and management of genetic diseases by analyzing the features detected in one or more facial images of affected indi...

Background: Growth hormone insensitivity (GHI) encompasses normal/elevated growth hormone (GH), low IGF-I levels and growth restriction. Non-classical/mild-moderate GHI is an emerging entity which is poorly characterised, and, in many subjects, the underlying cause is unclear. Heterozygous dominant negative (DN) variants located in the intracellular/transmembrane domain of the GH receptor (GHR) cause a ‘non-classical’ GHI phenotype.<p class="abst...

Background: Adults with CF show a higher rate of osteoporosis compared to healthy adults. Achieving proper bone mass is a process starting in childhood. We aimed to evaluate the prevalence of decreased bone mineral density (BMD), changes during puberty and risk factors for low BMD in children and adolescences with CF in a large Dutch cohort.Patients and methods: A retrospective observational cohort study was performed in...

Background: Bone age (BA) is commonly used in pediatrics to define skeletal maturity for medical and non-medical purposes. Normal range is represented by 2 standard deviations (SDs) above and below the mean. A BA greater than &pm;2 SDs from the chronological age (CA) is considered abnormal. BA in achondroplasia (ACH) has not been fully characterized; calculation is challenging given difficulties in comparing x-rays with standard radiographs if using the Greuli...

Background: Congenital central hypothyroidism (CeH) may occur isolated, or in combination with other pituitary hormone deficiencies. Although a third causative gene for CeH was recently reported (IGSF1), the aetiology of isolated CeH has remained unexplained in most cases.Objective and hypotheses: We hypothesized that in three relatives with unexplained isolated CeH a mutation in another gene might be responsible for the phenotype.<p class="...

Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...

Background: ACH, the most common short-limbed skeletal dysplasia, is characterized by defective endochondral ossification resulting from gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone formation. Current treatment options are non-targeted, ineffective, or painful interventions aimed at preventing or treating complications. Infigratinib is an orally bioavailable and selective...

Background: ACH is the most common short-limbed skeletal dysplasia, affecting between 1 in 15,000 to 1 in 30,000 live births. Children and adults with ACH have disproportionate short stature, with a final height of approx. 131 cm for males and 124 cm for females. People with ACH are prone to significant co-morbidities, including obstructive sleep apnea, chronic otitis media with conductive hearing loss, spinal stenosis, and a propensity towards obesity. In som...
