Objectives: We recently demonstrated that cow’s milk allergic infants who received an amino acid-based formula (AAF) for 16 weeks as oral feeding had adequate mineral status (1). One factor that may negatively affect mineral solubility and bioavailability and hence mineral status, is high gastric pH (2), but data on this in infants are lacking. Therefore, the present study evaluates serum concentrations of phosphorus, calcium and magnesium in a subgroup of infants on AAF ...

Introduction: Hereditary multiple osteochondromas (HMO) is characterized by the outward growth of cartilage-capped bone tumors. Osteochondromas contain a bone marrow cavity continuous with the normal bone cavity. Because of their off-axis position, osteochondromas are expected to carry less load than normal bone tissue. According to Wolff’s law, we therefore hypothesized that osteochondromas would have a less developed, osteoporotic-like microstructure. To test this hypot...

Childhood cancer has become curable in the majority (>70%) of patients. This is mainly due to rising intensity of treatment, including (combinations of) surgery, chemotherapy, radiotherapy and stem cell transplantation. In addition, intensive international collaboration for rare subgroups, enhanced stratification for treatment regimens and optimised supportive care has contributed to the improved survival of pediatric cancer that was accomplished over the last decades....

Like most organisms, we have developed an internal time keeping system that drives daily rhythms in metabolism, physiology and behavior, and allows us to optimally anticipate to the momentum of the day. At the basis of circadian timekeeping lies an intracellular molecular oscillator in which a set of clock genes cyclically regulate their own expression with an approximate (circa) 24-hour (dies) periodicity. The mammalian circadian system consists of a light-entrainable master ...

: This study analyses the long-term effect of rhGH on final height (FH) and bone health in renal transplanted patients.Twenty-one young adult patients, aged 17–26 years, were studied. Group A consisted of 15 patients (12 boys) who received rhGH during 3.0 years before transplantation. After transplantation three boys needed rhGH again for 3.5 years. In group B six patients (three boys) didn’t need rhGH before transplantation, three girls receiv...

Objectives: Metabolic bone disease is a frequent complication of end-stage renal disease, characterised by a decreased bone mineral density, which can be measured with dual-energy X-ray absorptiometry. Its validity as a marker for clinical bone disease and increased fracture risk has never been established in adults with pediatric onset of end-stage renal disease (1–3). Adult survivors of pediatric end stage renal disease have very low bone mineral density and small statu...

Objective: To investigate whether patients with secondary osteoporosis or other metabolic bone disease (SECOB) have a higher re-fracture or mortality risk.Method: Patients with a recent non-vertebral fracture who visited the Fracture Liaison Service (FLS) of a hospital were prospectively followed for 2 years. Pearson Chi-square, Fisher’s Exact test, independent samples T-test, and Cox regression models were used.Results: In to...

Background: In pediatric osteogenesis imperfecta (OI), bisphosphonates (BPs) are considered the best treatment option to increase bone density and reduce fracture rate. Pamidronate (PAM) is regarded as standard care for moderate to severe OI. The most recent added BP is intravenous zoledronate (ZOL). ZOL has practical advances over PAM, however research on its efficacy and safety is scarce.Objectives: To investigate the efficacy and safety of treatment w...

High resolution peripheral quantitative computed tomography (HR-pQCT) in combination with micro finite element analysis (μFEA) is a promising tool to assess longitudinal changes in bone mechanical properties during the fracture healing process in the distal radius. In the present study we investigate if these changes can be detected as well when using images with lower resolutions, comparable to clinical QCT images.Postmenopausal women with a stable...
