Iodine supplementation improves cognition in mildly iodine-deficient children

(Rosie Gordon, Meredith Rose, Sheila Skeaff, Andrew Gray, Kirstie Morgan and Ted Ruffman)
This groundbreaking study demonstrates for the first time that correction of even mild iodine deficiency in children can improve their ability to learn ...

100 years ago: The Nobel Prize goes to Swiss surgeon Theodor Kocher for research on goiter and the thyroid

(Hans Bürgi)
In 1909, the Swiss surgeon Theodor Kocher was awarded the Nobel Prize in Physiology and Medicine “for his work on the physiology, pathology and surgery of the thyroid gland”. Kocher had no choice but to get involved in the thyroid field: he was born, raised, trained, and appointed professor of surgery at the University of Berne, Switzerland and at that time the region was still ravaged by an incredibly high prevalence of goiter and cretinism. In 1883, in the city of Berne, 55% of schoolchildren had a goiter, often even a large nodular one. In 1923 the Canton of Berne (at that time with a population of about 600,000) housed 700 cretins in special institutions, in addition to those cared for by their family at home. So it is no wonder that of the 143 papers in Kocher’s publication list, 23 papers (16%) deal with the thyroid gland ...

Focus on IDD at the 9th World Salt Symposium in China includes an IDD Prevention and Control Workshop organized by the Ministry of Health

(Lucie Bohac)
The 9th World Salt Symposium took place in Beijing, China on Sept. 4-6, 2009. Organized by China National Salt Industry Corporation (a member of the Network for Sustained Elimination of Iodine Deficiency), the Symposium hosted approximately 1200 participants from over 50 countries ...

Elimination of iodine deficiency in Fiji

(A. Nisha Khan )
Iodine deficiency was recognized as a public health problem in Fiji in 1996 and universal salt iodization was introduced. A new national study shows the remark-able success of Fiji’s IDD elimination program ...

The importance of iodine in enteral and parenteral nutrition

(Michael B. Zimmermann )
Experts generally recommend iodine intakes of 30 to 60 g/kg/day for preterm infants (1). Formula milks for preterm infants contain 20 to 170 g iodine/L, and, depending on the dietary iodine intake of the mother, breast milk generally contains 50 to 150 g/L. Because oral absorption of iodine is efficient and oral iodine bioavailability is typically 90-95%, iodine dosages via the enteral (oral) or parenteral (intravenous) route should be nearly equivalent. However, commercially available par-enteral nutrition solutions contain much less iodine than breast milk or preterm formula milks. U.S. and European clini-cal nutrition societies recommend parenteral iodine intakes of 1 g/kg body weight/day ...

Thyroglobulin is a useful indicator of even mild iodine deficiency in adults

(Michael Zimmermann)
WHO/ICCICC/UNICEF currently recommend using thyroglobulin as a indicator of iodine status in children. A new Danish study suggests it is also useful in adults. In measuring the iodine status of a population, the recommended measures are primarily urinary iodine (UI) concentration and thyroid size. UI concentration reflects the recent (days) iodine intake but does not give any information about thyroid dysfunction ...
