OBJECTIVE To define non-bacterial osteitis (NBO) as a clinical entity possibly associated with autoimmune manifestations. Patients with sterile osteitis were analysed to develop diagnostic criteria. METHODS A total of 89 patients with non-bacterial inflammatory bone lesions were observed for a median of 49 months. History, diagnostic imaging, laboratory(More)
The aim of this cohort study was to assess the risk of developing cancer, specifically leukaemia, tumours of the central nervous system and lymphoma, before the age of 15 years in children previously exposed to computed tomography (CT) in Germany. Data for children with at least one CT between 1980 and 2010 were abstracted from 20 hospitals. Cancer cases(More)
From 1978 to 1987, 139 children were treated for osteomyelitis at our institution, among them 6 with osteomyelitis of the clavicle. All six patients presented with a primary chronic osteomyelitis. Three children sustained a trauma anamnestically. Pathohistological examinations revealed a chronic, unspecific inflammation in all cases. Immobilisation was(More)
PURPOSE Calculation of conversion coefficients for the reconstruction of organ doses from entrance doses for chest radiographs of 0, 1, 5, 10, 15, and 30-year-old patients in conventional pediatric radiology for the radiographic settings recommended by the German and European guidelines for quality management in diagnostic radiology. MATERIALS AND METHODS(More)
One hundred and ten children, ages 6 days to 14 years, were investigated for vesicoureteral reflux (VUR) using ultrasound before voiding cystourethrography (VCU). Sonographically a VUR was assumed if a retrovesical dilated ureter and/or an increase of the separation of the central renal echo complex (CRC) could be detected. By means of sonography VUR grades(More)
Background. Fluoroscopy is an important, sometimes vital radiological procedure in paediatric patients with high variability in frequency and technique. Objective. To obtain data on paediatric fluoroscopy practice in Europe using a simple questionnaire mailed to 191 children's hospitals. Results. Eighty-eight radiology departments in 21 European countries(More)
In order to assess human organ doses for risk estimates under natural and man made radiation exposure conditions, human phantoms have to be used. As an improvement to the mathematical anthropomorphic phantoms, a new family of phantoms is proposed, constructed from computer tomographic (CT) data. A technique is developed which allows any physical phantom to(More)
PURPOSE Analysis of all relevant data of X-ray examinations performed in a university children's hospital and stored electronically in a database since 1976. MATERIALS AND METHOD After 30 years of data gathering, the database now covers 276 739 radiological examinations (radiographs & fluoroscopies) of all age groups from newborns to adolescents. This(More)
OBJECTIVE Little is known about the long-term effects of exposure to diagnostic ionizing radiation in childhood. Current estimates are made with models derived mainly from studies of atomic bomb survivors, a population that differs from today's patients in many respects. MATERIALS AND METHODS We analyzed the cancer incidence among children who underwent(More)
The objective of this study was to develop and verify a new technique for monitoring the progression of osteoarthritis (OA) by combining a rat model with the imaging modality optical coherence tomography (OCT). Time-sequential, in vivo, OCT imaging was performed on the left femoral condyles of 12 Wistar rats following sodium-iodoacetic acid-induced OA(More)
