RT Journal Article SR Electronic T1 Dietary restriction causing iodine-deficient goitre JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 784 OP 786 DO 10.1136/archdischild-2015-308567 VO 100 IS 8 A1 Tim Cheetham A1 Emma Plumb A1 James Callaghan A1 Michael Jackson A1 Louise Michaelis YR 2015 UL http://adc.bmj.com/content/100/8/784.abstract AB Iodine-deficient goitre was common in some parts of the UK prior to the introduction of salt iodisation. Many contemporary salt preparations do not contain much iodine, and there are renewed concerns about the iodine status of the population. We present a boy with severe allergy who developed goitre and significant thyroid dysfunction in association with an iodine-deficient ‘food-restricted’ diet. The case highlights the importance of a comprehensive nutritional assessment in all children on multiple food restrictions.
