Attainment of normal height in severe juvenile hypothyroidism.
نویسندگان
چکیده
Prolonged juvenile hypothyroidism results in a permanent loss in height that is related to the duration of thyroxine deficiency before adequate thyroxine replacement treatment. A 13 year old girl with severe juvenile hypothyroidism was studied prospectively. She had an undetectable serum thyroxine concentration, a height SD score of -6.6 SD, and a bone age of 5.8 years. The enlarged pituitary gland involuted with thyroxine treatment to produce an empty sella. In addition to thyroxine the girl was treated with a gonadotrophin releasing hormone agonist to avoid the progression of puberty for 18 months and with growth hormone to achieve normal adult height.

Primary hypothyroidism in the juvenile population generally leads to retardation of linear growth and delay or even arrest of puberty. However, in rare conditions, children with long-standing hypothyroidism present with signs of Van Wyk-Grumbach's syndrome (VWGS) which include juvenile hypothyroidism, delayed bone age, and pseudoprecocious puberty.
