[Vitamin D-deficiency rickets: a case report from Burkina Faso]. / Le rachitisme carentiel: une observation au Burkina Faso.

ABSTRACT

Deficiency rickets results from a deficiency of vitamin D that is responsible for deficient calcium absorption, leading to failure of bone mineralization and cartilage bone growth, especially in children. We report the case of a 9-year-old girl who shows signs of rickets. Her family history, which includes similar malformations in several family members, led us to suggest vitamin D-resistant rickets, but all laboratory tests and response to treatment indicated deficiency rickets. Prophylaxis, at least for some very poor people, should be proposed for certain populations at risk, even in tropical zones.
