The antiarrhythmic drug, amiodarone, induces thyroid dysfunction, which is potentially dangerous in cardiac patients. After discontinuation of the drug it takes several months before euthyroidism is restored. The potent antithyroid drug, potassium perchlorate (KClO4), is used successfully to treat
BACKGROUND
Amiodarone-induced hypothyroidism (AIH) may occur in patients with or without underlying thyroid disorders. In the latter, restoration of euthyroidism, after amiodarone discontinuation, can be facilitated and accelerated by a short course of potassium perchlorate (KClO4). However, it is
We report a case of a patient with hypothyroidism due to amiodarone. The short-term administration (1 g/die for 10 days) of potassium perchlorate (KClO4) led to normalization of serum thyroid hormone concentrations and marked reduction of thyrotropic hormone. The reduction of KClO4 (400 mg/die) and
This concerns a case of an infant born with goiter and hypothyroidism whose mother had taken potassium iodide during pregnancy in the form of a respiratory eupneic syrup. Laboratory tests revealed the etiology of the goiter by demonstrating that it concerned a transitory, acquired hormone production
Iodide-induced hypothyroidism with high TSH and low T4 under long term potassium iodide medication was observed in a toddler suffering from chronic wheezy bronchitis -- in spite of intermittent application. The pathophysiology of iodide-induced hypothyroidism and the apparent immaturity of
This report describes a high school football player with an unusual ulcerative lesion on the upper leg that was treated initially as pyoderma gangrenosum, but later proved to be due to Sporothrix schenckii. His treatment with potassium iodide solution was complicated by the occurrence of subclinical
Changes in plasma renin activity (PRA) and plasma aldosterone (PA) were studied together with the urinary excretion of sodium and potassium in patients with hypothyroidism. The basal levels of PRA and PA were significantly less than those in normal subjects. However, there was no significant
Sporotrichosis is a subcutaneous mycotic infection caused by Sporothrix schenckii that is acquired by traumatic implantation. The diagnosis is established by demonstration of fungal elements on histopathology and culture. Potassium iodide, azole antifungals, and terbinafine are the treatment options
Epidemiological studies indicated that chronic exposure to high water iodine is associated with primary hypothyroidism (PH) and subclinical hypothyroidism (SCH). However, the mechanism is not well understood. In this study, we explored whether chronic exposure to high water iodine from potassium
We studied the effect of potassium perchlorate (KClO4) in patients with hypothyroidism due to amiodarone. The short term administration of KClO4 to six such patients led to prompt restoration of euthyroidism, while the three untreated patients remained hypothyroid for 2-6 months. Since KClO4
To evaluate whether hypothyroidism alters the adaptive responses of renal transport adenosine-triphosphatases (ATPases) to modifications in dietary K content, we examined the activities of Na-K pump and H-K pump in hypothyroid rats under basal conditions and after dietary K changes. Hypothyroidism
