Body Composition Measures on Different DEXA Scanners are not the Same

Meinhardt Udo , Witassek Fabienne , Fritz Christiane , Eiholzer Urs

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...

Bone Age Maturation in Prader-Willi Syndrome on GH Treatment is Accelerated in Pre-Pubertal Age without Affecting Final Height

Eiholzer Urs , Obwegeser Carla , Witassek Fabienne , Meinhardt Udo

Background: In children with Prader-Willi Syndrome (PWS) on Growth Hormone treatment (GHT) bone age (BA) acceleration is often observed. Little is known on reasons and consequences.Objective and hypotheses: To quantify BA acceleration in pre-pubertal PWS children on GHT and to investigate how BA correlates with weight gain and age at onset of GHT. To assess how final height depends on pre-pubertal bone maturation, weight gain and age at onset of GHT....
