[Hypervitaminosis D. Review of fifteen cases].

Fifteen cases of hypervitaminosis D in childhood are reviewed. In all of them, vitamin D was given following medical prescription. In four occasions, excessive dosage of vitamine D impaired the evolution of a previous nephropathy. The clinical, analytical, radiological and histological findings as well as the therapeutical aspects are commented. Hypercalcemia, hypercalciuria, polyuria with hypostenuria, renal failure, bone lesions and nephrocalcinosis are the most prominent features of the picture. Occasionally, arterial hypertension and glycosuria were found. Prednisone, thyrocalcitonine and phosphates were used as therapeutical means. In spite of nephrocalcinosis and renal failure generally present at diagnosis, the clinical course was rather good.
