Presentation
Leading experts from Latin America, Africa, Near and Middle East, Indian Subcontinent, Far East, Oceania and Australia present their expert insights into specific conditions, as well as progress and challenges in the development of the specialty. [books.google.com]
Rickets of the spine or pelvis, dental enamel defects, and tetany that occur in dietary vitamin D deficiency are rarely present in hypophosphatemic rickets. Patients with HHRH may present with nephrolithiasis and/or nephrocalcinosis. [msdmanuals.com]
PRESENTATION AND CLINICAL FEATURES Hypocalcaemia may be an incidental finding, or it can result in symptoms such as paraesthesia or cramps. [adc.bmj.com]
Rickets and/or osteomalacia is the presenting feature. Mild forms may present with hypercalciuria and nephrolithiasis without bone disease. [boneandspine.com]

Prognosis
Prognosis With consistent treatment, prognosis is good and skeletal deformities can be normalized, but growth rates usually remain subnormal. The documents contained in this web site are presented for information purposes only. [orpha.net]
