    Propranolol thyroid storm


    There are readily available and effective treatments for all common types of hyperthyroidism. Some of the symptoms of hyperthyroidism (such as tremor and palpitations, which are caused by excess thyroid hormone acting on the cardiac and nervous system) can be improved within a number of hours by medications called beta-blockers (eg, propranolol; Inderal). These drugs block the effect of the thyroid hormone but don't have an effect on the thyroid itself, thus beta blockers do not cure the hyperthyroidism and do not decrease the amount of thyroid hormone being produced; they just prevent some of the symptoms. For patients with temporary forms of hyperthyroidism (thyroiditis or taking excess thyroid medications), beta blockers may be the only treatment required. Once the thyroiditis (inflammation of the thyroid gland) resolves and goes away, the patient can be taken off these drugs. For patients with sustained forms of hyperthyroidism, such as Graves' disease or toxic nodular goiter, anti-thyroid medications are often used. The goal with this form of drug therapy is to prevent the thyroid from producing hormones. Thyroid storm is a rare clinical picture seen in severe thyrotoxicosis. The condition is a critical emergency presentation occurring in 1-2% of hyperthyroid patients, with treated mortality rates reported between 10-30%. While it can occur as the result of uncontrolled or poorly controlled hyperthyroidism, more often it is the result of an acute precipitating event acting on the increased catecholamine receptor expression of hyperthyroid patients. Precipitating Factors *It is always critical to rule out other causes of the clinical picture of thyroid storm, or previously mentioned acute conditions that provoked the condition. Supportive Care Pregnancy PTU has been the antithyroid drug of choice over methimazole, due to the belief that PTU does not cross the placenta as freely as methimazole. Furthermore, methimazole has shown to have congenital anomalies (aplasia cutis/choanal atresia). Recent studies have called these differences between the two drugs into question, but PTU is still the most widely used and accepted drug in pregnancy.

    Graves’ disease may include thyroid enlargement, ophthalmopathy, dermopathy, and hyperthyroidism. The most common cause of hyperthyroidism, this disorder occurs five to 10 times more often in women than in men, usually developing between the ages of 20 and 50 years. While the etiology of Graves’ disease is unknown, hereditary genetics has been implicated as predisposing an individual to developing the disorder later in life through environmental factors, such as smoking and stressful life events, or hormonal triggers like childbirth. This article will concentrate on the clinical presentation of Graves’ disease and currently available treatment options. Normally, the thyroid gland synthesizes, stores, and releases two kinds of hormones: thyroxine (T). Iodine obtained through dietary intake is absorbed via the gastrointestinal (GI) tract; it is used as iodide by the thyroid follicular cells and converted to either monoiodotyrosine (MIT) or diiodotyrosine (DIT). MIT and DIT undergo coupling to form T In Graves’ disease, however, the negative feedback system is superseded by thyroid-stimulating antibodies activating thyroid receptor cells in the same way that thyroid-stimulating hormone (TSH) stimulates the thyroid gland.
