During morphogenesis, embryonic progenitors proliferate, differentiate and establish the shape of the future organs and tissues. In the mature organism, a certain degree of plasticity and potential for regeneration is retained as most organs maintain a population of adult stem cells sharing important similarities with embryonic progenitors; they are characterized by the ability to both self-renew and differentiate into the full range of the specialized cell types corresponding...

Rapidly accumulating epidemiologic and experimental evidence has indicated that insufficient sleep, such as commonly experienced in modern societies by all age groups, reduces insulin sensitivity and impairs glucose metabolism in healthy adults, and increases the risk of incident type 2 diabetes. Studies in type 1 or type 2 diabetic adults show a link between reduced sleep quality or duration and poor glyceamic control. While poor diabetes control may impair sleep due to noctu...

Background: Several lines of evidence suggest that the adult pituitary contains a population of tissue-specific stem cells capable of differentiating into hormone-producing cells. Previously, we have shown that Sox2+ve cells are able to self-renew and differentiate in vitro, suggesting that this population of undifferentiated cells may contain stem cells in vivo. When targeted with oncogenic mutations adult stem cells can become cancer stem cells, able to self-renew and give r...

Management of DSD is a sensitive area within the field of paediatric endocrinology. On the one hand, major progress has been made in amongst others understanding the molecular genetic background and the germ cell cancer risk of certain DSD conditions. On the other hand, practices that were common in the past, such as early genital surgery have become strongly criticised and controversial nowadays, leaving clinicians as well as patients and their families with a lot of question...

Congenital adrenal hyperplasia (CAH) patients have a higher frequency of obesity, visceral adiposity, hyperinsulinism, insulin resistance and hyperandrogenism. There is increasing evidence that low vitamin D status is associated with impaired β-cell function, insulin resistance and impaired glucose tolerance.Objectives: This pilot aimed to determine the status of serum 25 (OH) D levels in CAH female patients who are followed up in Diabetes Endocrine...

Mineralization defects and paradoxical mineralizing enthesopathies are hallmarks of X-linked Hypophosphatemia (XLH), a rare skeletal disease caused by inactivating mutations in the PHEX gene (Phosphate-regulating endopeptidase homolog, X-linked). The current medical treatment, which consist in oral phosphorus supplementation and active vitamin D analogues, aimed at counteracting consequences of FGF23 excess and is commonly prescribed from early childhood to the end of...

Background: The circulating steroid metabolome in boys undergoes significant changes during infancy reflecting functional and structural rearrangements of the adrenal glands as well as the transient activity of the hypothalamic–pituitary–gonadal axis, also called minipuberty. Studies investigating the serum steroid metabolome dynamics during infancy in a longitudinal manner are however sparse.Objective: We ai...

Objectives: We describe 5 pedigrees with a novel phenotype including GHD associated with primary ovarian insufficiency (POI) and investigate the underlying molecular basis.Patients and Methods: 6 Turkish patients (5F, 1M) born to 5 consanguineous pedigrees with severe GHD were identified. All females had POI; the male had normal puberty. All had severe postnatal growth retardation (height -4.4 to -8.9 SDS at presentation...

Background: Congenital proopiomelanocortin deficiency (POMC) gene mutations cause early-onset obesity, hyperphagia and ACTH deficiency. In the subjects with this picture, neuropsychiatric (NP) features were rarely reported. Many Authors described an appetite loss during the topiramate treatment.Objective and hypotheses: To discuss NP features observed in a POMC deficient patient and to propose a therapeutic attempt to reduce the hyperphagia.<p class=...
