Many tissues in the body have vitamin D receptors. Maintenance of adequate vitamin D serum levels has been linked to a variety of health benefi ts. Vitamin D defi ciency, defi ned as a serum 25-hydroxyvitamin D level 20 ng/mL, is becoming a common issue as our population ages and sun exposure is minimized. Vitamin D defi ciency can lead to osteoporosis, muscle weakness, and increased risk of fa...

The mechanism of hypocalcemia in causing stridor might be a collapsing of larynx most likely caused by decalcifi cation due to hypocalcemia. Vitamin D defi ciency causes a reduction in serum calcium, which stimulates the production of extra P...

Vitamin D, discovered nearly a century ago, still receives intensive attention worldwide. In The Lancet today, Thomas Wang and colleagues, through a monumental eff ort by a large consortium of experts (the SUNLIGHT consortium), provide new data that help to explain the large variability of vitamin D status, as revealed by serum concentrations of 25-hydroxyvitamin D. Vitamin D defi ciency, even ...

Winter 2006 • Vol. 1 – No. 3 ABSTRACT Despite the availability of a wide variety of foods and supplements, and a growing interest in nutrition, the incidence of Vitamin D defi ciency is on the rise in the United States.
