The term apathetic thyrotoxicosis, where palpitations and cardiac involvement are the sole manifestations of disease, is well known. Thyroxin's ability to sensitize the catecholamine receptors causing tachyarrhythmias is well addressed. However, as an aetiology for advanced heart block,...

A severely thyrotoxic patient was found to have hypocalcaemia and tetany, which cleared when she became euthyroid. Cessation of treatment with propranolol and propylthiouracil resulted in a recurrence of the thyrotoxicosis and the reappearance of hypocalcaemia. Reinstitution of treatment resulted in a second remission of the thyrotoxicosis and correction of the hypocalcaemia. It is suggested th...

A 26 year old woman with lithium induced thyrotoxicosis is reported. The thyrotoxicosis was associated with a non-tender diffuse goitre and a low radioiodine uptake by the gland. The thyrotoxicosis was reversible and remitted on withdrawal of the drug. The histopathological alterations of the thyroid glad were characterised by extensive follicular cell disruption with no lymphocytic infiltratio...

The development of thyrotoxicosis following the administration of iodinated contrast is a rare occurrence. The effect, referred to as the Jod-Basedow effect, is often observed in patients with underlying thyroid disease who develop thyrotoxicosis subsequent to the exposure of exogenous iodide. An example of an iatrogenic cause for this event may be seen when a large iodide load is given intrave...
