RT Journal Article SR Electronic T1 Successful radioiodine treatment in a 3 year old child with Graves’ disease following antithyroid medication induced neutropenia JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 158 OP 159 DO 10.1136/adc.88.2.158 VO 88 IS 2 A1 M A S Rahman A1 G Birrell A1 H Stewart A1 H Lucraft A1 T D Cheetham YR 2003 UL http://adc.bmj.com/content/88/2/158.abstract AB A 3 year old child with Graves’ disease and mitral valve prolapse became neutropenic on carbimazole therapy. She was switched to propylthiouracil but the neutropenia recurred. She was treated with radioiodine but required two doses of 113 MBq and then 198 MBq five months later before becoming hypothyroid. The mitral valve prolapse resolved when she was euthyroid on thyroxine replacement. Antithyroid drugs, surgery, and radioiodine all have a place in the management of the thyrotoxic child.
