Iatrogenic vitamin D intoxiciation in infancy: Three cases
MetadataShow full item record
The potential hazards of excessive administration of vitamin D are well known. The increased intestinal absorption of calcium due to vitamin D over dosage leads to hypercalcemia and hypercalciuria that may give rise to the development of nephrocalcinosis, urolithiasis, and soft tissue calcification. Clinical features of three cases of iatrogenic vitamin D intoxication with different radiological findings were presented. The dose of vitamin D should be carefully determined in order to avoid vitamin D intoxication, and its complications. In addition, public health measures should be undertaken to prevent drug consumption without prescription that may be dangerous especially for children.
