[Disorders of the thyroid gland in neonates and youth: latent hypothyroidism and hyperthyroidism].
Etiology and clinical manifestation of subclinical hypothyroidism is different in neonates and in young. In the neonatal period babies present with jaundice and/or constipation due to thyroid hypoplasia, thyroid ectopia or transient hypothyroidism. The main reason for subclinical hypothyroidism in the youth is Hashimoto thyroiditis. Indication for thyroxin therapy in subclinical hypothyroidism is discussed controversial in the literature. For best growing and maturation in childhood thyroxin therapy should be given. Subclinical hyperthyroidism is rare in childhood. The main reasons are Graves' disease or Hashimoto thyroiditis (initial period). The therapy of subclinical hyperthyroidism is the same as in overt hyperthyroidism.
