Objectives: Bone mineral density (BMD) in children is generally measured with dual energy X-ray absorptiometry (DXA). Digital X-ray Radiogrammetry (DXR) is a promising alternative technique, that uses BoneXpert software to measure cortical BMD on hand radiographs, expressed as bone health index (BHI). DXR is a cheap method, is easy to apply in every hospital and involves less ionizing radiation compared to DXA. We aim to compare DXR and DXA measurements for determining bone de...

Background: The Ketogenic Diet Treatment (KDT) is a well-established intervention for intractable childhood epilepsy and the first choice treatment for Gluccose-1-transporter-deficiency-syndrome and Pyruvate-dehydrogenase-complex deficiency. During long-term follow up of children treated with KDT an increased incidence of bone fractures has been found. However, the exact contribution of KDT to a decreased BMD remains unclear. Prophylactic supplementation with calcium and vitam...

Objectives: To elucidate the incidence and risk factors of skeletal toxicity in children with ALL treated with the dexamethasone-based DCOG-ALL9 protocol.Methods: Prospectively, the cumulative incidence of fractures was assessed in 672 patients and compared between different subgroups using the log-rank test. Serial measurements of bone mineral density of the lumbar spine (BMDLS) were performed in 399 ALL patients using dual energy X-ray absor...

Objective: Nutritional rickets in Nigerian children is primarily due to dietary calcium deficiency and heals with calcium supplementation. Our aim was to determine the optimal dose of calcium for treatment of children with rickets due to dietary calcium deficiency.Methods: At the Jos University Teaching Hospital, 65 Nigerian children with radiographically-confirmed rickets were randomized to daily supplemental calcium intake of 500 mg (n=21), 10...
