XXXX -induced @entity1378 as combination of different etiologies: an overlooked entity in the elderly.

@entity1 @entity1496 @entity712 @entity64 @entity2643 @entity2743 @entity1376 @entity1378 @entity955 @entity6392 @entity715 @entity943 @entity479
UNASSIGNED: @entity1496 -induced @entity2743 , which raises several diagnostic and therapeutical challenges, is often overlooked. @entity1378 can induce @entity955 , a harmful @entity943 which can precipitate @entity712 and cause @entity64 . We report the case of an elderly @entity1 who was diagnosed with tachyfibrillation secondary to @entity1378 . Thyroid @entity6392 was subsequently related both to previous @entity2643 therapy (probably mixed form) and the recent use of iodinated contrast medium for computed tomography scan. Thyroid ultrasonography showed a @entity1376 . After initial worsening, thyroid function improved slowly but progressively on high-dose thyreostatic therapy combined with @entity479 therapy; tachyfibrillation caused @entity712 and a @entity715 in the left atrium, and proved initially resistant to combined antiarrhythmic treatments. Progressive reduction in thyroid hormone levels, together with combined cardiologic therapies, controlled the heart rate, though @entity955 persisted; anticoagulant therapy resolved the @entity715 . Alterations in thyroid function are common in @entity2643 -treated @entity1 , who therefore require regular hormonal checks. The different forms of @entity2643 -induced @entity2743 must be investigated, since they require different therapies, though mixed forms often occur. The superimposition of further @entity1496 excess due to other causes may be catastrophic and cause severe cardiac problems in these @entity1 .
