Background: The incidence of Type 1 diabetes (T1D) is rising globally and fractures are common.Objective: To investigate bone health in young females with a T1D duration of at least 10 years in relation to healthy, matched controls.Subjects: Twenty-three Swedish females, aged 19.2– 27.9 years, with a T1D duration of ≥10 years, were recruited from the Swedish National Dia...

Background: There is limited information on the ability of demographic or lifestyle factors to predict short term changes in weight status during childhood.Objective and hypotheses: To study the effect of parental (educational level, BMI status and perception of child’s weight status) and childhood factors (eating habits, sedentary behaviour and physical activity), on 1-year BMI increments by the use of BMI, BMI SDS and BMI SDS conditional gain....

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...

Context: Infants and toddlers with Prader-Willi Syndrome (PWS) have a mental and motor developmental delay. Short-term data suggest a positive effect of growth hormone (GH) on mental and motor development in infants and children with PWS. There are, however, no longer-term results about the effects of GH treatment on mental and motor development.Objective: To investigate the longer-term effects of GH on psychomotor development in infants and toddlers wit...
