Background: Congenital adrenal hyperplasia (CAH), due to 21-hydroxylase deficiency is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000, and even more common in some populations. Do carriers have a survival advantage?Objective and hypotheses: The HPA axis has been reported to be more active in CYP21A2 carriers, and possibly enable a more rapid return to homeostasis. A compensatory increase in CRH s...

Background: Congenital adrenal hyperplasia (CAH) is a relatively common monogenic recessive disorder with an incidence of 1/15 000 in most populations. It has been suggested that CYP21A2 deficiency is relatively common because it may confer a survival advantage to be a carrier. Carriers of CYP21A2 mutations typically do not have clinical symptoms but have a defined phenotype. The cortisol response to ACTH stimulation has been shown to be both...

Background: Growth patterns in early childhood are important for predicting adult overweight or obesity. BMI is the most widely used measure. However BMI does not reveal much regarding the distribution of fat, for example the visceral fat that in adults is highly correlated with metabolic risk. Waist-to-Height Ratio (WtHR) is in adults a better measure for visceral fat and studies indicate that the same applies to children.Objective and hypotheses: To st...

Summary Answer: Most primordial/primary oocytes were found to have a 46,XX karyotype. Chromosome patterns of the ovarian cells were different from that observed in other tissues.Background: TS is a chromosomal condition associated with partial or complete absence of one of the two X-chromosomes. Females with TS have a limited reproductive lifespan due to an accelerated loss of germ cells. It has been hypothesized that vi...

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Introduction: Well-known long-term complications of alloHSCT in childhood include endocrine system damage and secondary malignancies. In addition, adults surviving childhood alloHSCT are at risk of cardiovascular (CV) and metabolic disturbances. Long-term data of physical fitness in correlation with metabolic status are scarce in this particular group.Objective/Patients and Methods: Cross-sectional investigation of exerc...

Summary Answer: The majority of the expert panel states that ovarian tissue cryopreservation (OTC)should be offered to young females with Turner syndrome (TS)Background: OTC is a valid option to preserve the fertility of young females at risk of iatrogenic premature ovarian insufficiency (POI). Offering OTC to females with a genetic cause of POI seems a logical next step. One of the most common genetic disorders related ...

The transient activation of the hypothalamus-pituitary-gonadal (HPG) axis shortly after birth has been described as early as in the 70ies. This discovery has since been applied clinically as a ‘window of opportunity’ for diagnostic evaluation of patients suspected of endocrine disorders and differences of sex development. With the advent of increasingly more sensitive and specific analytical methods for peptide and steroid hormones produced in the pituitary, gonads...

Background: In later life, osteoporosis and poor cognitive function often co-exist. This has commonly been attributed to post-menopausal estrogen loss, but there is increasing recognition of cross-talk between the brain and bone. For example, in animal models, bone derived osteocalcin has positive associations with brain volume and cognitive function whilst brain-derived neurotransmitters appear to influence bone mass. Despite this, a common early life origin ...

Background: GH treatment is proven to increase adult final height in some pathology and first year response is assumed as an index of treatment’s effectiveness.Objective and hypotheses: Identify the prevalence of each indication in children treated with GH in our hospital and evaluate the first year response to treatment.Method: We retrospectively analysed the files of 30 patients followed for short stature and on GH treatment...
