Coexistence between thyroid cancer and hyperthyroidism is rare, most of the nodular lesions from which a malignant tumor documented in this group patients correspond to cold nodules. Justified by increasing number reports literature about tumors diagnosed hot nodules, systematic review was carried out determine possible factors associated with diagnosis nodules hyperthyroidism. The results sugg...

Background Graves' hyperthyroidism affects 0.2% of pregnant women. Establishing the correct diagnosis and effectively managing Graves' hyperthyroidism in pregnancy remains a challenge for physicians. Main The goal of this paper is to review the diagnosis and management of Graves' hyperthyroidism in pregnancy. The paper will discuss preconception counseling, etiologies of hyperthyroidism, thyr...

In 232 Japanese patients receiving long-term amiodarone therapy for life-threatening ventricular tachyarrhythmias, hyperthyroidism and hypothyroidism developed in 29 patients (12.5%) and 25 patients (10.8%), respectively. In patients with hyperthyroidism, the recurrence of sustained ventricular tachycardia was significantly higher with thyrotoxicosis than in the euthyroid period (31% vs 3%, p<0...

Cardiovascular complications are important in hyperthyroidism because of their high frequency in clinical presentation and increased mortality and morbidity risk. The cause of hyperthyroidism, factors related to the patient, and the genetic basis for complications are associated with risk and the basic underlying mechanisms are important for treatment and management of the disease. Besides cell...

We investigated the effect of hyperthyroidism on the responsiveness of the rabbit corpus cavernosum smooth muscle. In male albino rabbits, hyperthyroidism was established by oral feeding of L-thyroxine at increasing dosages (150-450 microg/kg) over an 8-week period. This treatment produced a stable hyperthyroid state as indicated by the increased serum T4 levels. The reactivity of corpus cavern...

Hyperthyroidism is associated with many heart diseases. Thyrotoxic state has a relationship with coronary spasm. We present a case of a non-menopausal woman with hyperthyroidism who complained of chest pain. The diagnosis of coronary spasm was confirmed by coronary angiography (CAG). She is treated well with anti-thyrotoxicosis and anti-anginal medication. We recommend not use CAG as the first ...

Benign thymic hyperplasia (BTH) is a known feature of hyperthyroidism, but is infrequently appreciated by clinicians. In most cases thymic enlargement is minimal; however, it may occasionally present as an appreciable anterior mediastinal mass. While surgical resection is a common approach to such a mass, recognition of the benign nature of BTH and its regression following treatment of hyperthy...

Iodine-induced hyperthyroidism can develop even in the presence of an otherwise normal gland. One of the less common sources of iodine is tablets of seaweed, sold over the counter without prescription. We report the case of a 72 year old female who developed clinical and laboratory evidence of hyperthyroidism while ingesting sea-kelp (Vitalia) tablets. Six months after stopping the tablets, the...

BACKGROUND In humans, measurement of serum thyroid-stimulating hormone (TSH) concentration is commonly used as a first-line discriminatory test of thyroid function. Recent reports indicate that canine TSH (cTSH) assays can be used to measure feline TSH and results can help diagnose or exclude hyperthyroidism. OBJECTIVES To investigate the usefulness of cTSH measurements as a diagnostic test f...

Hyperthyroidism is specified by the mass manufacture of thyroid hormone and/or release from gland. Thyrotoxicosis a sickness in which impacts an inappropriate enhancement on tissues lead to difficulties and systemic symptoms. High levels cause hyper metabolic condition that induces multiple manifestations. Managing hyperthyroidism cases considered difficult challenge because variety underlying ...
