Current hormone substitution therapy of patients with congenital adrenal hyperplasia (CAH) is suboptimal and cannot mimic physiological daily rhythms of hormone secretion. As supra-physiological corticoid doses are necessary to avoid adrenal androgen excess, patients show substantially increased comorbidities such as hyperglycemia, arterial hypertension, reduced growth and osteoporosis. Moreover plasma ACTH is often inadequately suppressed, resulting in undesired excess adrena...

Background/Aim: 25 to 40% of children with well-controlled X-linked hypophosphatemia (XLH) show linear growth failure, despite optimal conventional treatment (oral phosphate supplementation and active forms of vitamin D) with final height -2 SDS. Recombinant human growth hormone (rhGH) may be an adjuvant treatment of the growth retardation in these patients. Therefore, the main objective of this study was to describe how rhGH treatment improves final heigh...

Background: The mitochondrial enzyme nicotinamide nucleotide transidrogenase (NNT) is essential in the antioxidant defense mechanisms and appears to be essential to the stages of adrenal steroidogenesis that occur inside the mitochondria.Aim: To characterize how mutations in NNT gene impair adrenal steroidogenesis resulting in familial glucocorticoid deficiency (FGD).Methods: Genom...

Introduction: Turner's syndrome (TS) is associated with several manifestations the most frequent being short stature and hypogonadism. Some authors (Nadeem, 2012; Bakalov, 2008) reported that individuals with TS have increased risk of fractures, but the etiology and mechanism of bone fragility have not been yet fully elucidated and may be exacerbated by hormonal factors (Cintron, 2017; Soucek, 2015). Bone densitometry (BD) through the emission of double en...

Objective: Recent studies have suggested earlier onset of pubertal development in boys. As assessment with orchidometer tends to overestimate true testicular volume (TV), and measurements based on ultrasound (US) have been proposed as a more reliable method, we present US based references in 6-16 year-old Norwegian boys. Our results are compared with data from Europe and the United States (U.S.) in order to establish evidence for an ongoing secular trend in ma...

Background: Using ultrasound to examine the glandular breast tissue is a promising method for staging pubertal breast development. However, breast ultrasound for this purpose has not been explored in a large sample of healthy girls in different developmental stages, and normative data have been unavailable.Objective: To present novel pubertal references for breast ultrasound stages, Tanner breast (B) and pubic hair (PH) ...

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...

Background: Emerging evidence suggests a link between the intestinal microbiota and cardiometabolic outcomes in both children and adults. The oral microbiota is less studied, and the association between the oral microbiota and cardiometabolic health in childhood remains largely unknown.Objective: To explore the associations between oral microbiota diversity measured at 8-10 yr and cardiometabolic health in childhood and ...

Background: Oral microbiota composition and diversity differ between obese and non-obese individuals. However, the associations between lifestyle habits (implicated in the pathogenesis of obesity) and the oral microbiota remain uncertain, particularly among children.Objective: To explore the associations between oral microbiota diversity and lifestyle habits among 8-10 year-old children.Met...
