Background: Osteogenesis imperfecta is a rare collagen related hereditary disease leading to recurrent fractures, reduced mobility, muscular weakness and short stature.Objective and hypotheses: It was always discussed if the reduced height is a consequence of the impaired collagen production, a reaction of the body to the brittleness of bones or if the patient might suffer from an additional deficiency of growth hormone (GH).Method...

Introduction: Congenital deficiency of the leptin receptor is an extremely rare cause of early-onset monogenic obesity with rapid weight gain and compulsive overeating. LEPR mutations is responsible for extreme form of obesity associated with other endocrine abnormalities and respiratory tract infection. Till date, approximately 50 families have been reported to have mutations in the leptin receptor gene.Case: 9-year-old...

Beckwith-Wiedemann Syndrome (BWS) is an overgrowth disorder, occurring in 1/13,700 births. BWS is usually sporadic, but 15% of cases are familial. Variable phenotype may include overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycemia, lateralized overgrowth and predisposition to embryonal tumors. We describe three male cases of BWS followed at our clinic.Case 1: Born of a gestation complicated by gestational diabetes. Del...

Introduction: Ox in a dose of 0.03-0.05 mg/kg per day in addition to GH treatment significantly increases adult height in TS more than GH alone. To date, the long term effects of Ox in childhood on bone mineral density (BMD) in adulthood are unknown.Methods: This is a follow-up study of a previous randomized controlled trial, performed in the Netherlands. In the original trial, 133 girls were treated with GH. Placebo (Pl...

Background: Autoimmune primary adrenal insufficiency (PAI) is a rare and life-threatening disease. Standard replacement therapy consists of multiple daily doses of hydrocortisone combined with fludrocortisone. A recent Endocrine Society guideline argued against hormonal monitoring of glucocorticoid replacement. However, about 50% of adolescents and young adults (AYAs) with chronic diseases are non-adherent to their prescribed treatment regimens. Pervasive nonadherence places p...

Objectives: Bone health is affected in Type-1-Diabetis (T1D) causing higher risk of hip fractures, prolonged fracture healing and altered bone mineral density (BMD). In T1D adults BMD is found to be decreased. In this study we have measured the BMD in children and adolescents from the Copenhagen Pediatric T1D Cohort.Methods: 276 children and adolescents (131 girls) were included from the diabetes outpatient clinic at Herlev University Hospital. All patie...

Background: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...

Background: Rett (RTT) syndrome is a neurodevelopmental disorder related to mutations in the MECP2 gene that affects girls almost exclusively. In Rett syndrome patients have a high incidence of fractures that can occur at a young age.Objective and hypotheses: One of the objectives of this study was to identify clinical, radiographic and biological parameters associated to fracture incidence.Method: 89 RTT patients bearing a MEC...

Background: Birth chest circumference (BC) may be related to Insulin-like-Growth-Factor-I blood serum levels (IG1) in the human newborn (NWB).Objective and hypotheses: We evaluated the relevance of birth body weight (BW) to birth crown-heel length (BL) ratio (BW through BL, BW/BL) in BC relations to IG1 after control for BW for birth gestational age (GA)<=10th centile (SGA), respiratory oxygen supplementation (O2S) and assisted ventilation of any kin...

Background: There is growing evidence of a correlation between fat and bone metabolism at both the clinical and molecular levels, although the systemic regulators have not been clearly identified. The receptor activator of nuclear factor kB ligand (RANKL) and its soluble decoy receptor, osteoprotegerin (OPG), are involved in bone resorption and vascular calcification. OPG levels has been related with insulin resistance in adult obese subjects.Objective a...
