Background: Vitamin D may have cardio-protective properties due to its biological actions. In children, observational studies linking actual vitamin D level and blood pressure have yielded conflicting results. Whether early life vitamin D exposure may elicit a programming effect on later systolic blood pressure (SBP) and diastolic blood pressure (DBP) needs further investigation.Objective and hypotheses: We investigated whether higher levels of cord 25-h...

Background: Pycnodysostosis is a rare recessive condition with mutation in the cathepsin K gene, causing reduction in bone reabsorption resulting in abnormally dense and fragile bones. Characteristic features include deformity of the skull, maxilla causing craniofacial, dental abnormalities with skeletal changes and short stature. Growth hormone therapy has been attempted in a small group of patients with Pycnodysostosis to promote final adult height, however has not been show...

Background: Polycystic ovary syndrome (PCOS) in adolescence has a challenging diagnosis and therefore has raised intense discussions. Its prevalence in childbearing age women ranges from 5 to 10%. However, the prevalence in obese adolescents has not yet been reported. Besides, the relationship of PCOS with metabolic and cardiovascular disorders in this specific population has not been established.Objective and hypotheses: We aimed to assess the prevalenc...

Background: Hypogonadotrophic hypogonadism (HH) is a complex developmental disorder characterized by a reduction in gonadotrophins (LH, FSH) released from the anterior pituitary. LH and FSH stimulate the ovaries or testes to release sex hormones that cause the onset of puberty, therefore delay in onset or complete absence of puberty is seen in the phenotype, often accompanied by short stature and genital abnormalities. When anosmia accompanies HH in the phenotype it is termed ...

Background: Familial glucocorticoid deficiency (FGD) is a rare and potentially life-threatening disease, characterized by adrenal insufficiency without mineralocorticoid deficiency. It is diagnosed during the neonatal period but also in childhood. Manifestations are recurrent hypoglycemia, seizures or even coma, chronic fatigue, recurrent infections and skin hyperpigmentation. Mutations on mineralocorticoid receptor 2 (MC2R) gene and on melanocortin-2 receptor accesso...

Background: Since the late 1960’s, pubertal breast staging has been based on Tanner’s classification. Appearance of glandular breast tissue may be difficult to distinguish by palpation from the surrounding subcutaneous fat tissue, especially in obese girls. To our knowledge, validation of the clinical assessment of pubertal stages by MRI quantification of glandular breast tissue has never been performed.Objective and hypotheses: i) To report no...

Background: In humans, loss-of-function mutations in Nicotinamide nucleotide transhydrogenase (NNT) cause familial glucocorticoid deficiency, a potentially fatal, adrenal-specific disorder characterized by increased ACTH and reduced cortisol levels. NNT is a highly conserved inner mitochondrial membrane protein, which supplies high concentrations of NADPH for detoxification of reactive oxygen species (ROS) by glutathione and thioredoxin pathways.<p class="abstext"...

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: Early TS diagnosis permits early GH start and estradiol (E2) supplementation approaching adult height (AH) at normal age and within a normal range. However, higher age at diagnosis is still a challenge.Objective and hypotheses: The hypothesis from our long-term trials will result in knowledge for personalized treatment in order to obtain a psychological acceptable age at onset of puberty and still an attained AH within normal range...

Background: Severe obesity (SO), defined as BMI ≥95th percentile, has increased worldwide among adolescents. American studies estimated that 1.3–2.8% of 12–19-year-old individuals have a BMI >40 kg/m2 or a BMI >35 kg/m2 with at least one serious co-morbidity. The immediate and long-term risks associated with SO in adolescents include cardiovascular and metabolic diseases, obstructive sleep apnoea, and nonalcoholic fatty liver disea...
