Increased secretion of thyroid hormones
In what sex is hyperthyroidism more common
Ten times more common in women than men
What is the most common cause of hyperthyroidism
Graves disease (80%–90% of U.S. cases)
What are some other causes of hyperthyroidism
Plummer disease (toxic adenoma); toxic multinodular goiter; subacute thyroiditis; amiodarone therapy
What are some of the signs and symptoms of hyperthyroidism
Autoimmune disease causing hyperthyroidism. It is due to antibody stimulation of TSH receptors causing excess secretion of free thyroid hormone.
What are the two symptoms only seen in Graves disease
1. Pretibial myxedema
2. Infiltrative ophthalmopathy
What is pretibial myxedema
Pruritic, non pitting edema found on shins that usually remits spontaneously
What is infiltrative ophthalmopathy
Exophthalmos that may not resolve despite treatment of Graves disease most likely due to
autoimmune damage in extraocular muscles
How is Graves disease diagnosed
All hyperthyroidism is diagnosed via measurement of TSH, free T4, and free T3. In Graves disease, since there is excess stimulation of the thyroid gland causing increased production of thyroid hormone, laboratory tests show high levels of free T4 and free T3, and low levels of TSH (because of negative feedback) Also, a radioactive iodine uptake scan should be done. If uptake is low, then thyroiditis or medication-induced hyperthyroidism is considered.
What is another name for toxic multinodular goiter
Plummer’s disease
What is the underlying cause of hyperthyroidism in Plummer disease
Multiple thyroid nodules develop autonomous T4 secretion and, therefore, more T4 is released.
How is Plummer disease diagnosed
Radioactive iodine uptake tests show “hot” nodules with the rest of the gland being “cold”;also, clinically ,nodules can sometimes be felt.
What is another name for subacute thyroiditis
de Quervain thyroiditis
What are the signs and symptoms of subacute thyroiditis
Prodrome of viral urinary tract infection (UTI) followed by rapid onset of thyroid swelling and tenderness as well as hyperthyroid symptoms that can later turn into a hypothyroid state.
What is the treatment for de Quervain thyroiditis
Usually self-limiting, but asprin and corticosteroids may be indicated to control inflammation
What are the treatment options for a hyperthyroid state
1. Medication: propylthiouracil (PTU) or methimazole
2. Radioactive iodine ablation
3. Surgery: subtotal thyroidectomy
What is the first-line treatment for Graves disease
Radioactive iodine ablation
What is radioactive iodine ablation
Radioactive iodine is concentrated in the gland and destroys tissue
What are the possible side effects of radioactive iodine ablation?
Hypothyroidism; thyrotoxic crisis secondary to the release of thyroid hormone into the blood stream
What is the mechanism by which PTU works
It inhibits the peripheral conversion of T4 to T3, decreases iodine uptake, decreases T4 synthesis
Do patients need to be on therapy for the rest of their lives
No. After a 1–2 year course of treatment about 50% no longer need to be treated.
What is the potential side effects of PTU?
Leukopenia, rash, nausea
What other adjunctive treatment is given to patients with hyperthyroidism
Beta-blocker,usually propranolol, to control symptoms
What is the most serious complication of hyperthyroidism?

What can induce thyroid storm
Infection, surgery, trauma, abrupt stop of antithyroid medication, serious acute medical problems such as cerebrovascular accident or myocardial infarction
What are the signs and symptoms of thyroid storm
Exaggerated symptoms of hyperthyroidism are tachycardia, high outputcongestive heart failure (CHF), abdominal pain, fever, altered mental status (ultimately coma)
What is the mortality rate of thyroid storm

What is the initial treatment for thyroid storm?
It is an emergency so think of the ABCs:
Airway stabilization
Breathing/oxygen administration
Circulation (check pulse/blood pressure [BP]) and start IV fluids

What other lab results are present in primary hypothyroidism

What laboratory results can help diagnose Hashimoto thyroiditis

What is subacute thyroiditis
Tender,enlarged thyroid; often post-viral infection can begin with hyperthyroid symptoms, then hypothyroid symptoms
How can you distinguish Hashimoto from subacute thyroiditis
On clinical examination, in Hashimoto the thyroid gland isnot tender to palpation but in subacute thyroiditis it istender to palpation.
How can Graves disease and increased Hashimoto’s thyroiditis be distinguished
Radioactive iodine uptake is with Graves and decreased with Hashimoto.
What is secondary hypothyroidism
Hypothyroidism caused by pituitary dysfunction
What are some examples of secondary hypothyroidism
