Thyrotoxicosis causes a variety of symptoms and adverse health outcomes. Hyperthyroidism refers to increased thyroid hormone synthesis and secretion, most commonly from Graves' disease or toxic nodular goitre, whereas thyroiditis (typically autoimmune, viral, or drug induced) causes thyrotoxicosis without hyperthyroidism. The diagnosis is based on suppressed serum concentrations of thyroid-stimulating hormone (TSH), accompanied by free thyroxine and total or free tri-iodothyronine concentrations, which are raised (overt hyperthyroidism) or within range (subclinical hyperthyroidism). ⋯ Treatment options for hyperthyroidism include antithyroid drugs, radioactive iodine, and thyroidectomy, whereas thyroiditis is managed symptomatically or with glucocorticoid therapy. In Graves' disease, first-line treatment is a 12-18-month course of antithyroid drugs, whereas for goitre, radioactive iodine or surgery are preferred for toxic nodules or goitres. Evidence also supports long-term treatment with antithyroid drugs as an option for patients with Graves' disease and toxic nodular goitre.

We describe the clinical course of two patients who developed tracheal compression and deviation by multinodular goiter (MNG). Case 1: A 66-year-old woman presented with thyroid swelling. Five years after the initial admission, she was diagnosed with hyperthyroidism by Graves' disease and increased bilateral thyroid lobes compressing the trachea. ⋯ Thyroglobulin was elevated from 122 to 392 ng/mL. Two cases and literature review indicated that MNG with >50 mm, solid components, and extension to the mediastinum or paralarynx were risk factors of tracheal compression and deviation. Monitoring thyroglobulin elevation can help predict the clinical course.

There is an increased incidence of thyroid nodules and cancer. In this article, the reasons for this increase are evaluated and discussed. The factors causing increases in the incidence of nodules are the same as those causing increases in thyroid cancer. ⋯ This paper has described many of the factors causing this higher incidence. Of note, metabolic syndrome and insulin resistance are important factors associated with the increased incidence of nodular goiter and papillary thyroid cancer today. However, these data must be confirmed by other studies in the future.

Review[Recommendation for Calcitonin Screening in Nodular Goiter].
Medullary thyroid cancer (MTC) arises from parafollicular C cells of the thyroid gland and is characterized by a calcitonin secretion. Basal calcitonin correlates with the tumor mass and is used as highly sensitive and specific tumor marker for MTC. Based on former assays, unspecific calcitonin increase has frequently been seen in Hashimoto's thyroiditis, kidney insufficiency, proton pump inhibitors etc. ⋯ Lower calcitonin values should be re-evaluated in intervals of 3 - 6 months; rising calcitonin levels may indicate an MTC. In this case, thyroid operation should be performed. The cure rate of MTC with calcitonin values < 100 pg/ml is nearly 100 % done by high volume surgeons.

Thyroidectomy is still three to six times more common in Germany than in the USA, Great Britain, and the Scandinavian countries. Thus, the question is often asked whether thyroidectomy in Germany is being performed for the correct indications. ⋯ The decision to operate should be made on an interdisciplinary basis and in conformity with the relevant guidelines after all of the appropriate diagnostic studies have been performed. The radicality of any proposed surgical procedure should be weighed against its potential complications.
