[Hypothyroidism in pregnant women].

Ten pregnant women with hypothyroidism and 10 newborns born to these women were studied. In 3 pregnant women the infantile and juvenile type of hypothyroidism were diagnosed. In 6 women hypothyroidism resulted from partial or total thyroidectomy (for toxic goitre or papillary carcinoma), and in one it was a result of Hashimoto's thyroiditis. In all studied women the serum levels were determined of thyrotropin (TSH), thyroxine (T4) and triiodothyronine (T3). The pregnant patients were treated with thyroid hormones such as L-thyroxine or thyroidin. All newborns of these women were evaluated clinically and the levels of TSH, T4 and T3 were determined in them.
