Care for patients is the best way to learn medicine and medical methods and skills. But the availability of real patients for learners is limited. Often the appropriate patient is missed or he can not be demonstrated to all students because of practical or ethical problems. A possible solution is the presentation of a clinical problem by a virtual patient(More)
We describe an outbreak of Pneumocystis jirovecii pneumonia in a pediatric renal transplant unit, likely attributable to patient-to-patient transmission. Single-strand conformation polymorphism molecular typing showed that 3 affected patients had acquired the same 2 strains of Pneumocystis, which suggests interhuman infection. An infant with(More)
Impairment of longitudinal growth among children with chronic renal failure (CRF) may be partly attributable to the inhibition of insulin-like growth factor (IGF) activity by an excess amount of high-affinity IGF-binding proteins (IGFBP). Elevated levels of immunoreactive IGFBP-4 in CRF serum are inversely correlated with the standardized heights of these(More)
BACKGROUND E-learning and blended learning approaches gain more and more popularity in emergency medicine curricula. So far, little data is available on the impact of such approaches on procedural learning and skill acquisition and their comparison with traditional approaches. OBJECTIVE This study investigated the impact of a blended learning approach,(More)
INTRODUCTION Data on the efficacy and safety of everolimus in pediatric renal transplantation compared to other immunosuppressive regimens are scarce. PATIENTS/METHODS We therefore performed a multicenter, observational, matched cohort study over 4 years post-transplant in 35 patients on everolimus plus low-dose cyclosporine, who were matched (1:2) with a(More)
BACKGROUND Despite the increasing interest in medical education in the German-speaking countries, there is currently no information available on the challenges which medical educators face. To address this problem, we carried out a web-based survey among the members of the Association for Medical Education (Gesellschaft für medizinische Ausbildung, GMA). (More)
Since many drug targets and metabolizing enzymes are developmentally regulated, we investigated a potential comparable regulation of inosine 5’-monophosphate dehydrogenase (IMPDH) activity that has recently been advocated as a pharmacodynamic biomarker of mycophenolic acid (MPA) effects in the paediatric population. Since the field of pharmacodynamic(More)
Mycophenolic acid (MPA) is an immunosuppressive drug widely used in the prevention of acute rejection in pediatric renal transplant recipients and is characterized by a wide inter-individual variability in its pharmacokinetics. The aim of this study was to compare population pharmacokinetic modeling of MPA in pediatric renal transplant recipients given(More)
