What is Jod Basedow phenomenon?
Jod-Basedow phenomenon occurs due to either overactivation of the entire thyroid gland or, more commonly, autonomous nodules within the gland after iodine repletion without adequate feedback control from the pituitary gland. This escape from the protective Wolff-Chaikoff effect is called the Jod-Basedow phenomenon.
Is Rai safe for Graves disease?
While it is generally safe to give RAI, patients may experience some side effects of therapy. The risk of eventual hypothyroidism is high, especially after treatment of GD. There can be transient exacerbation of hyperthyroid symptoms due to radiation thyroiditis.
Does radioactive iodine cure Graves disease?
Though it can occur at any age it is most commonly diagnosed in women aged 40–60 years [2]. Treatment options include antithyroid drugs, radioiodine therapy (I131) and surgery. Radioiodine is a safe and effective definitive treatment for Graves’ disease.
Can iodine induced hypothyroidism be reversed?
Recently, iodine-induced reversible hypothyroidism has been well documented mostly by Japanese investigators. Reversible hypothyroidism occurs occasionally at the recovery phase of postpartum hypothyroidism, subacute thyroiditis, and painless thyroiditis. Such cases were excluded by the patients’ history.
Can CT scan affect thyroid?
Jan 25 (Reuters) – The iodide dye used in heart scans and other medical imaging, such as CT scans, may in some cases damage patients’ thyroid glands, possibly leading to health problems such as thyroid disease later on, according to a U.S. study.
Do you pee out excess iodine?
When iodide enters the circulation, the thyroid gland concentrates it in appropriate amounts for thyroid hormone synthesis and most of the remaining amount is excreted in the urine [2].
Does methimazole help anxiety?
Methimazole blocks the synthesis of thyroid hormone, but often beta blockers such as metoprolol are also used to treat some symptoms, especially the fast heart rate, anxiety and tremor. Beta blockers work quickly and are usually prescribed as soon as hyperthyroidism is diagnosed.
