Background: Published case reports and anecdotal experience suggest a positive effect of dexamphetamine on impetus and weight in patients with hypothalamic obesity.Objective and hypotheses: We aimed to observe these effects in our patients who are offered off-label treatment with dexamphetamine.Method: Between 2010 and 2013, patients starting dexamphetamine treatment were enrolled in a prospective observation study. BMI–SDS wa...

Background: Published case reports and anecdotal experience suggest a positive effect of dexamphetamine, a CNS stimulant on impetus and weight in patients with hypothalamic obesity. Based on these observations, patients presenting to our obesity clinic with hypothalamic obesity are offered off-label treatment with dexamphetamine.Method: Between 2010 and 2015, patients starting dexamphetamine treatment were enrolled in a prospective observation study. A r...

Introduction: Hereditary causes of rickets often take longer to be diagnosed because they are not very frequent. 1α-hydroxylase alteration is the most frequent vitamin D-dependent rickets. A delay in the treatment associated to a late diagnosis generates an abrupt parathormone deficiency. When initiating treatment, these patients have a risk of hungry bone syndrome.Case: 2-year-8-month-old male patient, with a history of psychomotor...

Background: Growth hormone therapy can be indicated for children who are born small for gestation age (SGA) (either birth weight or birth height < -2 SDS) without catch-up growth (height < -2.5 SDS) at age 4 years. Growth hormone therapy is considered a safe treatment.Case presentation: A 12-year-old girl was referred to the pediatric endocrinologist for short stature. She was born small for gestational age (birth ...

Background: Child growth is a dynamic process and influenced by various environmental factors. When measured at short intervals, growth of healthy children shows certain characteristic patterns, which have rarely been studied, but are of great importance for clinical purposes. The study was approved by the Ethical Committee of the University of Potsdam.Aim: To see whether measurements of height using photographic display...

Background: Body composition measures differ between DEXA scanners. If an old DEXA is replaced a transition period for double measurements on the old and the new scanner is needed.Objective and hypotheses: To evaluate differences between the old (Hologic QDR 2000) and new (Hologic Discovery Wi) scanner and to calculate formula transforming measurements.Method: 51 double measurements were performed on a group of 41 children and adul...

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a regulator of IGF-1 availability, causes postnatal growth failure in humans and mice, at least in part through dysregulation of bone size and density. The present study aimed to determine the effects of Pappa2 gene deletion and the response to recombinant murine IGF-1 (rmIGF-1) on femur microstructure and composition. Hydroxyapatite-related crystallography and ionic substitutions were analyzed by X-ray p...

Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability affecting postnatal growth. Mutations in human PAPP-A2 cause short stature and changes in bone size and mineral density. The present study aimed to characterize the effects of constitutive Pappa2 gene deletion on hypothalamic regulation of energy homeostasis in adult male and female mice. In addition to being sho...

Background: Obesity interventions often result in increased motivation to eat after weight loss.Objective: We investigated relationships between obesity outcomes and changes in brain activation by visual food cues and hormone levels in response to obesity intervention by family-based behavioral treatment (FBT).Design, Methods, and Participants: Functional neuroimaging and plasma ho...

Shwachman-Diamond syndrome (SDS) is a rare congenital disease, which is caused by SBDS gene mutations. The main characteristics of SDS are pancreatic exocrine deficiency, hematological dysfunction, and skeletal growth failure. Emerging data from case reports and patient registries suggest, that SDS could also be associated with an increased risk for diabetes mellitus. Additionally, a small number of case reports in the literature describe a susceptibility to hypoglycaemia as a...
