Thyroid associated ophthalmopathy due to radioactive iodine therapy in patient with right thyroid toxic adenoma

Abouglila Kamal

Thyroid-associated ophthalmopathy (TAO) is an inflammation of the extraocular muscles and periorbital connective tissue caused by autoantibodies against common antigens to both the thyroid and orbit. The release of antigens and induction of hypothyroidism caused by radioactive iodine (RAI) therapy may cause or exacerbate TAO. Radioactive iodine therapy has been associated with worsening TAO, particularly in smokers. A 57 years old female treated with radioactive iodine therapy...

Rhabdomyolysis associated with severe hypothyroidism

Marta Lubczynska Malgorzata , Macriyiannis Thrasos , Gohil Shailesh

Patients with clinical hypothyroidism often complain of muscular symptoms i.e., cramps, weakness and fatigue. However, rhabdomyolysis triggered by severe hypothyroidism is rarely reported. In most cases, external triggers (use of statins or excessive exercise) can be easily identified and modified. In absence of beforementioned triggers, it is prudent to look for other causes of rhabdomyolysis. On the forefront, it would be crucial to exclude myocardial ischaemia, followed by ...
