Background: The BoneXpert method for automated determination of bone age (BA) from hand X-rays was introduced in 2009, covering the Greulich-Pyle BA range up to 17 years for boys and 15 years for girls.Objective and hypotheses: To present an extension of the BA range of the automated method up to 19 years for boys and 18 years for girls and to validate it against manual rating.Method: The extension was developed based on images fro...

Background: Cerebral infarction (CI) is a known vascular complication following treatment of suprasellar tumors. The purpose of our study was to determine the incidence of cerebral infarction (CI) in a cohort of 244 German childhood-onset craniopharyngioma (CP) patients recruited between 2007 and 2019 with a high degree of completeness in the prospective, randomized trial KRANIOPHARYNGEOM 2007 (Clinical Trial No. NCT01272622). Up to now, risk factors for CI, i...

Background: Childhood-onset craniopharyngioma patients (CP) often suffer from tumor or treatment-related hypothalamic lesions (HL). These lesions may alter production of oxytocin, which plays a major role in the regulation of eating behavior and body composition.Objective: In CP with different degrees HL, we investigated associations between HL, eating behavior/eating attitudes, and oxytocin saliva concentrations (OSC).<...

Background: DKA in children and adolescents with established type 1 diabetes (T1D) is a major problem with considerable cost to patients, families and health care systems. Many consider it as a quality of care indicator and a failure of relationship between the care provider and the family/patient. Considerable variability in rates are recognized. We analyzed multicenter registry and audit data from five countries with similarly advanced, yet differing, health care systems.</p...

Background: Despite high survival rates in childhood craniopharyngioma, prognosis is frequently impaired due to sequelae. Radical surgery was the treatment of choice for several decades. However, even at experienced surgical facilities radical surgery can result in hypothalamic disorders such as severe obesity.Objective and hypotheses: We analyzed, whether treatment strategies for childhood craniopharyngioma patients recruited in German studies (KRANIOPH...

Background: Quality of life and long-term prognosis are frequently, often severely impaired in craniopharyngioma (CP) patients.Objective and hypotheses: Knowledge of risk factors for long-term outcome is important for optimisation of treatment.Method: Overall survival (OS) and progression-free survival (PFS), BMI, neuropsychological status (EORTCQLQ-C30, MFI-20), and psychosocial status were analysed in 261 patients with childhood-...

Background: Paediatric patients with sellar masses such as craniopharyngioma (CP) or cyst of Rathke’s pouch (CRP) frequently suffer disease- and treatment-related sequelae.Objective and hypotheses: We analysed the impact and prognostic relevance of initial hydrocephalus (HY) and hypothalamic involvement (HI) on long-term survival and functional capacity (FC) in children with CP or CRP.Method: Using retrospective analysis of pa...

Background: Cerebral infarction (CI) is a known vascular complication following treatment of suprasellar tumors. Risk factors for CI, incidence rate, and long-term prognosis are unknown for patients with childhood-onset craniopharyngioma (CP).Methods: MRI of 244 CP patients, recruited between 2007 and 2019 in KRANIOPHARYNGEOM 2007, were reviewed for CI. Risk factors for CI and outcome after CI were analyzed.<p class=...

Background: The BoneXpert method for automated determination of bone age from hand X-rays is based on machine learning, so it lends itself naturally to be improved by adding more training data and using better learning algorithms. Currently, version 2 is running in 145 hospitals across Europe, and a new version 3 is rolled out in 2019.Objective and Hypotheses: The aim was to validate version 3 against manual ratings in r...

Background and aim: PTEN hamartoma tumor syndrome (PHTS) is caused by germline mutation in the phosphatase and tensin homolog (PTEN) gene. PTEN is a tumor suppressor gene and antagonist of the growth and survival signalling Phosphoinositide 3-kinase (PI3K)/AKT/mammalian target of Rapamycin (mTOR)- cascade. Patients with PHTS, amongst other symptoms, develop lipomas, for which the underlying mechanism is not completely understood. To investigate the role of PTE...
