In October, 1999, his 63-year-old father came to the emergency department with similar complaints. He was also in acute renal failure and denied a history of renal stones. showed the same biochemical profile. Kidney biopsies of… Expand
Acute Vitamin D Intoxication in a Child
This case highlights the need for caution when using imported and/or unregulated medicines, as well as the dangers of parental dosing errors, in a previously healthy, 2-year-old boy with resistant hypercalcemia and hypertension resulting from an unintentional overdose with an imported vitamin D supplement.

Unusually prolonged vitamin D intoxication after discontinuation of vitamin D: possible role of primary hyperparathyroidism
It seems that an underlying primary hyperparathyroidism that was masked initially by the hypercalcemia of vitamin D intoxication was responsible for the unusually prolonged half-life of 25(OH)D in the blood. Expand
Vitamin D Intoxication Due to an Erroneously Manufactured Dietary Supplement in Seven Children
In conclusion, errors in manufacturing of dietary supplements may be a cause of VDI in children and Physicians should be aware of this possibility in unexplained VDI cases and repeatedly question the families about dietary supplement use. Expand
Toxicity of Vitamin D
It is reasonable to increase the upper limit for vitamin D to at least 10,000 IU/day, because the production of vitamin D in the skin is controlled by sunlight and there is no concern about making too much ofitamin D from excessive exposure to sunlight. Expand

Hypercalcemia Due to Vitamin D Toxicity
Abstract Although vitamin D toxicity is an uncommon cause of hypercalcemia, it becomes a consideration after exclusion of the more frequent causes such as primary hyperparathyroidism and malignancy.Expand
Age-related changes in the 25-hydroxyvitamin D versus parathyroid hormone relationship suggest a different reason why older adults require more vitamin D.
All age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism, and older adults are just as efficient in maintaining 25( OH)D, but they need more vitamin D to produce the higher vitamin D concentrations required to overcome the hyperparathiroidism associated with their diminishing renal function.

A family with massive acute vitamin D intoxication
Before phosphate therapy it was shown that both parents were in strongly negative calcium balance, indicating that the vitamin D was mobilizing calcium from bone, and neutral phosphate was successful, although necessary for 9 months. Expand
Vitamin D intoxication associated with an over-the-counter supplement.
A patient with hypercalcemia associated with the ingestion of an over-the-counter vitamin D supplement is described, which is lifesaving at physiologic levels and dangerous at megavitamin levels. Expand
An outbreak of hypervitaminosis D associated with the overfortification of milk from a home-delivery dairy.
The overfortification of milk with vitamin D can lead to hypervitaminosis D, manifested by severe illness and death, and highlights the need for monitoring the fortification process and enforcing the upper limit for vitamin D addition to milk. Expand
Serum Levels of Free 1,25-Dihydroxyvitamin D in Vitamin D Toxicity
This hypothesis that the high levels of 25-OHD could cause an increase in free levels of 1,25-(OH)2D (despite normal total levels), which might be responsible for the changes in calcium homeostasis is tested. Expand
Efficacy and safety of vitamin D 3 intake exceeding the lowest observed adverse effect level 1 – 3
