Case histories.

The conditions related to abnormalities of calcium and bone metabolism are large in number and cover problems of hypocalcaemia, hypercalcaemia, primary and secondary osteoporosis, rickets resulting from both vitamin D and phosphate metabolic disorders, and a series of miscellaneous conditions. Included in this chapter is a series of 36 cases drawn from our clinics and from colleagues who have presented these clinical problems at recent Advanced Courses in Paediatric Bone and Calcium Metabolism run by the British Paediatric and Adolescent Bone group. The series of cases is not fully comprehensive but is designed to cover the major aspects of bone and calcium related disorders and can be added to online in due course.
