Predisposition to vitamin D deficiency osteomalacia and rickets in females is linked to their 25(OH)D and calcium intake rather than vitamin D receptor gene polymorphism
Clinical Endocrinology, 08/20/2009
|
Ray D et al. – Among the immediate family members of patients with OSM/rickets, female sibs have features of biochemical OSM in up to 24 ... with patients features of markedly low serum 25(OH)D levels, poor dietary calcium intake and poor exposure to sunshine. Genetic factors such as VDR and PTH gene SNPs were not associated with OSM/rickets.

Hip and Knee Arthroplasty in Hypophosphatemic Rickets
Journal of Arthroplasty, 08/14/2009

Larson AN et al. – One cemented THA failed due to femoral aseptic loosening at 13 years postoperatively; all other implants remained well fixed. Lower extremity arthroplasty is effective and durable for patients with arthritis associated with hypophosphatemic rickets, but corrective

Hypophosphatemic Rickets with Hypercalciuria due to Mutation in SLC34A3/Type IIc Sodium-Phosphate Cotransporter: Presentation as Hypercalciuria and Nephrolithiasis
Journal of Clinical Endocrinology and Metabolism, 10/15/2009
|
Tencza AL et al. – The authors report a novel mutation in the SLC34A3 gene in a patient with an unusual presentation of HHRH ... mutations in the SLC34A3 gene, respectively, providing further evidence for a gene dosage effect in determining the phenotype. HHRH may be an underdiagnosed condition that can masquerade as idiopathic hypercalciuria or osteopenia.

The Journey From Vitamin D-Resistant Rickets to the Regulation of Renal Phosphate Transport
Clinical Journal of the American Society of Nephrology, 11/16/2009
|
Levine BS et al. – Using a conceptual approach, we suggest that a defect in the skeletal response to parathyroid hormone contributes to hyperparathyroidism in XLH. Finally, at the end of the review
