Fetal thyrotoxicosis in a euthyroid woman should be treated by maternal administration of antithyroid drugs plus thyroxine replacement. Women with maintenance dose of carbimazole prior to pregnancy should be switched to PTU during pregnancy as it has fewer side effects. There is an increased risk of miscarriage associated with Grave’s disease. Treatment with PTU is known to cause IUGR. Continuous fetal monitoring during labour is not recommended for women on PTU. Up to 10% of thyroid nodules discovered during pregnancy can be malignant. Radioactive iodine scan can be done in 3rd trimester if indicated Back to top Hadia Koomary Joined: 15 Sep 2008 Posts: 42 Posted: Fri Oct 03, 2008 9:52 am    Post subject: Quote: In a woman with newly diagnosed thyrotoxicosis, beta blockers can be continued through out pregnancy.

False Beta-blockers can be used during pregnancy to help treat significant palpitations and tremor due to hyperthyroidism. They should be used sparingly due to reports of impaired fetal growth associated with longterm use of these medications. Typically, these drugs are only required until the hyperthyroidism is controlled with anti-thyroid medications.

False All thyroid nodules should be evaluated; up to 40 percent are found to be malignant. Therefore all thyroid nodules in preganncy have to be evaluated.

TRUE I think i'll agree with you as antithyroid medication will cross the placenta and can optimise fetal thyroxin level , while adminstration thyroxin to the mother will help optimise maternal thyroid hormon only as it does not cross placenta.

In maternal thyrotoxicosis complicating pregnancy an increase in the size of thyroid indicates inadequate treatment. Neonatal goitre is a recognized complication of overtreatment.

False Can still occur if TrAB is present as in Graves Neonatal thyrotoxicosis due to persistence of maternal TRAbs occurs in about 1% of babies born to mothers with either active or previously treated Graves' disease and lasts for up to 3 months Back to top cpeedahsa Century Club Joined: 21 Apr 2007 Posts: 921 Posted: Thu Oct 09, 2008 8:38 pm    Post subject: bluesky wrote: Neonatal goitre is a recognized complication of overtreatment. True The goal of therapy is to keep the mother’s free T4 and free T3 levels in the high-normal range on the lowest dose of antithyroid medication. Targeting this range of free hormone levels will minimize the risk to the baby of developing hypothyroidism or goiter.

False Potential side effects of antithyroid medications are pruritus, skin rash, urticaria, fever, arthralgias, cholestatic jaundice, lupuslike syndrome, and migratory polyarthritis. Leukopenia -medication effect;also seen in untreated Graves' disease; WBC count before treatment is started. Agranulocytosis is the most severe complication, but fortunately it is uncommon.
