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 ...

Background: Rickets is a disorder of the growing child arising from impaired mineralisation of the growth plate and osteoid. The most common cause of NR in the UK is thought to be secondary to vitamin D deficiency [VDD; serum 25-hydroxyvitamin D (25OHD) <25 nmol/l], although in some African & South Asian countries dietary calcium deficiency (DCaD) by itself, or together with VDD is an important cause of NR (Ann Trop Paediatr. 2006;26:1–16). Currently, the data on ...

Objective: Evaluate the clinical characteristics of all Latin American pediatric patients with Gaucher disease type 1 (GD1) enrolled in the ICGG Gaucher Registry at baseline and investigate long-term outcomes and clinical benefit of prolonged imiglucerase/alglucerase therapy in patients with manifestations of GD1 at baseline.Methods: All Latin American patients with GD1 in the ICGG Gaucher Registry (NCT00358943) who were <18 years of age at the start...

Using a longitudinal observational study with two evaluations and a 1 year follow-up interval, we investigated the influence of everyday physical activity (PA) and skeletal geometry in bone mineral density (BMD) and bone mass distribution at the proximal femur (PF) in 96 girls and 81 boys (10–12 years). Whole body and left hip DXA scans were used to derive geometric measures of the pelvis (inter acetabular distance – IAD) and PF (abductor lever arm – ALA). BMD w...

Background: There is still limited information on changes in growth especially segmental growth and bone mass of glucocorticoid(GC) treated boys with Duchenne Muscular Dystrophy (DMD).Objectives: To evaluate changes in growth and bone mass in GC treated boys with DMD.Methods: Retrospective study of 15 boys with DMD treated with GC, median age 7.6 years (4.1, 15.5) who had repeated DXA scan for clinical monitoring of bone health, me...

Objectives: Creation of reference curves for areal bone mineral density (aBMD) and bone mineral content (BMC) with consideration of relevant anthropometric variables.Methods: Analysis of the dual-energy X-ray absorptiometry (DXA) data collected as part of the Bone Mineral Density in Childhood Study1, including 2012 boys and girls, 5–22 years old, with a total of 10 525 visits, resulting in aBMD and BMC observations at the lumbar spine, hi...

Peripheral computed tomography (pQCT) can estimate volumetric bone mineral density (vBMD) and distinguish trabecular from cortical bone. Few comprehensive studies have examined correlates of vBMD in Spanish premenopausal women.The aim was to study the association between bone microarchitecture, muscle mass and strength in premenopausal Spanish women and to evaluate the role of calcium intake. vBMD was assessed in 164 premenopausal women at the distal rad...
