How can you tell the difference between hyperthyroidism and thyrotoxicosis?

Hyperthyroidism refers to increased thyroid hormone synthesis and secretion from the thyroid gland, whereas thyrotoxicosis is characterized by the clinical manifestations of inappropriately high thyroid hormone action in tissues.

How does hyperthyroidism cause molar pregnancy?

Molecular variants of hCG found in molar pregnancies have increased thyrotropic potency (7). When gestational trophoblastic disease causes a significant rise in hCG levels, it may induce hyperthyroidism that requires treatment. As expected, thyrotoxicosis resolves with treatment of GTD and normalization of hCG levels.

Which neurological manifestation is associated with hyperthyroidism?

Encephalopathy — Cognitive impairment is common in hyperthyroidism and may present as one or more different syndromes. In a cross-sectional study of older hospitalized patients, dementia and confusion were found in 33 percent and 18 percent of patients with hyperthyroidism [1].

What is thyroid Acropachy?

Thyroid acropachy is a rare complication of autoimmune thyroid disease with characteristic imaging findings. Clinically, it presents as nail clubbing, swelling of digits and toes, almost always in association with thyroid ophthalmopathy and dermopathy.

Why do you get preeclampsia with molar pregnancy?

Molar pregnancy is associated with very early-onset preeclampsia. Since excessive circulating anti-angiogenic factors may play a pathogenic role in preeclampsia, we hypothesized that molar placentas produce more anti-angiogenic proteins than normal placentas.

Does hCG affect thyroid levels?

When the concentrations of hCG are very high (ie >200,000), as can be seen in the first trimester of pregnancy, it may actually turn on the thyroid gland and cause it to make extra thyroid hormone (thyroxine [T4] and triiodothyronine [T3]) which, in turn, may turn off the production of TSH from the pituitary.
