Background: Anorexia nervosa (AN), a state of chronic nutritional deprivation prevalent in children and young adolescents, is associated with major changes to the hypothalamic–pituitary axis including the GH–IGF1 axis, thyroid function, hypercortisolemia, and hypogonadotropic–hypogonadism, with delayed puberty and a low growth velocity (GV) at a time critical for the pubertal growth spurt, potentially affecting adult height. The effects of supraphysiological hum...

Background: Obesity is characterized by an increase in fat mass caused by an increase in adipocyte number and adipocyte size and is often associated with adipose tissue (AT) dysfunction contributing to metabolic impairment. It is suspected that adipocyte progenitor cells play an important role during healthy and obesity-related AT expansion. Studies in adults showed that the stroma vascular fraction (SVF) of AT is composed of different progenitor cell subpopul...

Background: Clinical observations of children and adolescents with differentiated thyroid cancer (DTC) patients led us to investigate quality of life and anxiety. Although adult DTC survivors have similar or slightly worse quality of life (QOL), this has not been evaluated in the pediatric population.Objective and Hypotheses: In this cross-sectional pilot study, our objective was to compare QOL and anxiety in adolescents with DTC to patients with acquire...

The epidemic spread of obesity in children has triggered the commitment of scientific research, which has allowed us to understand its genetic basis; the different forms of genetic obesity share common clinical aspects, making it difficult to achieve a molecular diagnosis based only on our clinical suspicion. We report a female patient presented with neonatal hypotonia, hyperphagia and early onset excessive weight gain, strabismus and high hypermetropia. Regarding her neurodev...

Obesity, with its complications, emerges as a major contributor to the global health burden becoming pandemic. It's an extremely complex disorder resulting of interaction of biological, social and behavioural factors that cause increase in food intake and reduction in energy expenditure. Although few monogenic forms and indeed several susceptibility loci have been described, the molecular basis underlying early onset obesity remain largely unknown. GWAS revealed consistent...

Background: The growth and IGF1 responses to GH treatment show a large variation across children with idiopathic short stature (ISS). Compliance and GH regimens are important determinants. The d3 variant of the GH receptor (GHR) is a significant genetic predictor. The role of individual epigenetics had not been studied. The IGF1 locus is an attractive candidate where CG methylation could influence GH action.Objectives: To study GH effects on a) IGF1 gene...

Background: Medullary thyroid cancer (MTC) in MEN 2A is caused by mutations in RET. Guidelines (2001/2009/2015) recommend prophylactic total thyroidectomy (TT) based on mutation specific risk levels (ATA 2015: high/moderate).Objective: The aim of this study was to analyse changes of age at TT, frequency of metastatic MTC (MMTC), and frequency of TT according to guidelines since introduction of RET testing in 1995....

Background: Short stature has several causes ranging from complex hormonal deficiencies mostly related to pituitary gland genetics, to idiopathic and environmental causes such as maternal smoking in pregnancy, etc. Floating harbor syndrome is a rare genetic disorder characterized by short stature, delayed bone age, mild to moderate mental retardation, retarded speech development, and typical facial dysmorphic features. The syndrome is caused by heterozygous mutations in exon 3...

Background: The thyroid gland is a common unintended target during and after cancer treatment in childhood cancer survivors. However, only a limited number of studies have assessed thyroid adverse events of newer or more selective anticancer drugs. The main objectives of this review are to provide an overview of thyroid disorders in children, treated with 131 I-metaiodobenzylguanidine (131 I-MIBG), tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibi...

Background and methods: Sellar and suprasellar tuberculomas are extremely rare in children and most often patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. Here, we report a girl with hypothalamic obesity, that recovers after antituberculosis treatment.Findings: An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephal...
