Background: Chromosome analysis is always indicated in disorders of sex development (DSD), but the need for karyotyping in gender dysphoria (GD) is less clear.Aims and objectives: We therefore aimed to review the place of routine chromosome analysis in the management of GD in children and adolescents.Patients and methods: 490 children and adolescents with GD have been referred to the two endocrine clinics forming part of the joint ...

Objective: Advanced glycation end products (AGEs) increased oxidative stress and promote inflammation, resulting in the cellular damage, by interacting with their receptor (RAGE) on cell membrane. By contrast, the soluble receptor for AGE (sRAGE), that is proteolytically cleaved from cell surface receptor via matrix metalloproteinases, sequester RAGE ligands and act as a cytoprotective and anti-inflammatory agent. AGEs-RAGE/sRAGE interaction is deemed to play a role in the pat...

Background: Birth chest circumference (BC) may be related to Insulin-like-Growth-Factor-I blood serum levels (IG1) in the human newborn (NWB).Objective and hypotheses: We evaluated the relevance of birth body weight (BW) to birth crown-heel length (BL) ratio (BW through BL, BW/BL) in BC relations to IG1 after control for BW for birth gestational age (GA)<=10th centile (SGA), respiratory oxygen supplementation (O2S) and assisted ventilation of any kin...

Management of type 1 diabetes in preschool children is a huge challenge for their caregivers. Age-specific factors (e.g. unpredictable food intake and physical activity, small insulin doses, high insulin sensitivity, frequent intercurrent infections, high variability in insulin requirements) increase the complexity of daily diabetes management. Furthermore, the preschool child depends completely on his/her caregiver. To meet recommended treatment targets while avoiding hypogly...

I review the mental health difficulties that transgender and gender diverse children and adolescents may present with, specifically emotional difficulties. Many studies reveal depression scores and parent and self-reported measures of emotional and behavioral problems that are comparable to mental health clinic referred populations. Children and adolescents who feel that they are acknowledged and supported in their gender diverse feelings, e.g. by receiving gender affirming me...

The phenotype of 45,X/46,XY mosaicism is heterogeneous ranging from females with Turner syndrome (TS) to apparently normal males. Cardinal features of TS include reduced final height and infertility. Apart from endocrine, renal and neurocognitive disorders, structural heart defects are frequently present (in 25% to 50%), also in TS patients with mosaicism 45,X/46,XY. Males with 45,X/46,XY frequently show stigmata typically associated with TS but data on cardiovascular patholog...

Central precocious puberty (CPP) may have endocrine and metabolic implications in adulthood. Long-term effects may be associated with the underlying neuroendocrine dysfunction leading to CPP, the GnRH analogue (GnRHa) therapy, or both. Data are conflicting on the long-term risk of polycystic ovarian syndrome in both treated and untreated women. Clinical hyperandrogenism has been more frequently reported in CPP women than in controls, with no significant difference between GnRH...

Anthropometrics is an important part of pediatrics and public health. Its non-invasiveness, simplicity and low cost makes anthropometry attractive for several purposes. It is a valuable method for the screening or assessment of growth disorders, as well as under- and over-nutrition. Furthermore, specific anthropometric measures can be used as indicators of general fitness or cardiovascular risk factors (insulin resistance and dyslipidemia) in (obese) children, as well as marke...

Puberty is defined by the appearance of secondary sexual characteristics and the maturation of reproductive function. It is driven by an increase in sexual steroid hormone synthesis under the control of the gonadotropic axis. The key event in puberty initiation is an increase in the pulsatile release of the GnRH by hypothalamic neurons, triggering the release of LH and FSH. This pubertal increase in GnRH secretion is associated with increases in glutamatergic inputs and decrea...

Patients with type 1 diabetes (T1D) and their caregivers continue to face the challenge of maintaining blood glucose levels in the near-normal range, preventing sustained hyperglycemia associated with long-term microvascular and macrovascular complications, and avoiding recurrent episodes of hypoglycemia, especially at young ages when they can adversely affect cognitive function. In a follow-up to the Diabetes Control and Complications Trial, the Epidemiology of Diabetes Inter...
