Background: Many cross-sectional studies have demonstrated that serum testosterone concentration is an important biochemical predictor of bone mineral density in young males, but to our knowledge, no longitudinal studies have been carried out to support these cross-sectional data.Aims: to examine the associations between serum testosterone concentration at the age of 12 and the following gain in bone mineral density unti...

Background: The GH/IGF1 axis has important roles in growth, metabolism, lipid profile and body composition. GH receptor disrupted mice (GHRKO mice) are resistant to the action of GH, thereby, GHRKO mice are dwarf, hypoinsulinemic, hypoglycemic and obese. Consumption of a high fat diet (HFD) induces inflammatory processes in a multitude of peripheral tissues, including hypothalamus.Objective and hypotheses: Our aim was to evaluate the effect of HFD intake...

Background: Whilst adhering to the highest standards of data governance and security, the International DSD Registry (www.i-dsd.org) and the International CAH Registry (www.i-cah.org) allow standardised collection of data and promote multicentre collaboration across national boundaries and across multiple clinical and research disciplines.Results: By April 2015, over 1600 cases had bee...

Introduction: Kisspeptin stimulates the gonadotropin releasing hormone (GnRH) neurons in hypothalamus initiating puberty. However, it is not known whether GnRH inhibits kisspeptin secretion by negative feedback and whether there are any associations between circulating levels of kisspeptin and other hormones, like ghrelin, important for the onset of puberty.Methods: Thirteen girls with suspected central precocious pubert...

Introduction: Delayed puberty is defined as the absence of physical signs of puberty by the age of 14 years in boys and 13 years in girls. According to this definition, the prevalence of delayed puberty would be 2%, if the ages of pubertal onset were normally distributed in the population. However, the prevalence or incidence of delayed puberty has not been described before, as far as we know. Our aim was to study the incidence of delayed puberty in central Sweden.<p class...

Introduction: Ghrelin is a growth hormone-releasing acylated peptide stimulating the appetite, mainly produced in the stomach, and with an important role in pubertal development (1). Two ghrelin forms have been described, acylated (AG) and desacylated (DAG), but it is debated whether DAG is an active hormone or a degradation product of AG (2). Our aim was to evaluate the effects of adding the protease inhibitor 4-(2-aminoethyl) benzenesufonyl fluoride hydrochl...

Introduction: McCune - Albright syndrome is rare genetic disorder characterized by periphereal precocious puberty, fibrous bone dysplasia and cafe au lait skin spots.Case: Almost 5 years old girl was sent to Endocrinological department due to precocious thelarche and menarche. At the time of first examination, patient had breast M 3 and large cafe au lait macule on the right tight, no pubic and axilar hair was present, n...

Noonan syndrome is a genetic condition caused by dysregulation of RAS-MAPK pathway (RASopathy) characterized by great clinical variability and genetic heterogeneity. Many genes has been associated with the disease, including recently LZTR1, which is causative of both dominant and recessive forms. Currently less than one hundred cases of Noonan syndrome has been associated with LZTR1 variants then phenotype related to this gene is poorly known. Here we describ...

Context: Children with Prader-Willi syndrome (PWS) generally have mild to moderate cognitive impairment with an IQ between 60 and 70. Growth hormone (GH) treatment is a registered treatment for children with PWS and has been associated with cognitive benefits, attributed to the effects of GH and insulin-like growth factor on brain growth and development. Short-term data suggest positive effects of GH treatment on cognitive functioning in children with PWS. The...

Progeria syndromes are rare in children and include several diseases which lead to premature ageing already in children. Therefore, the pediatrician may be confronted with diseases which are normally seen only in persons with advanced age. We report about two children with progeria, in whom diabetes type 2 become manifest early and with a fulminant course in one patient. The first boy was known with Cockayne syndrome, which belongs to the progeria syndromes. He suffered from l...
