Thyroid disease in the emergency department. Thyroid function tests and hypothyroidism and myxedema coma.

The recognition of hypothyroidism may not always be easy in the emergency department setting. Laboratory evaluations of thyroid function are not usually performed on a 24-hour basis, and therefore the emergency physician, although suspecting the presence of hypothyroidism, may be unable to confirm the diagnosis while the patient is in the Emergency Department. It is not always the responsibility of the emergency physician to diagnose hypothyroidism, but in some clinical settings it may be important to include thyroid function tests in laboratory evaluation of patients to ensure adequate patient care and followup. Careful attention to nonspecific complaints, myxedematous changes, and signs of dysfunction of any organ system, especially in older female patients, may lead to the ultimate correct diagnosis. Myxedema coma is potentially fatal and must be recognized and treated emergently, usually prior to laboratory confirmation. Ventilatory support and thyroid hormone replacement are the two most important therapeutic maneuvers in the treatment of myxedema coma.

Gastric mucosa-associated lymphoid tissue in autoimmune thyroid diseases.

BACKGROUND: There is increasing evidence for a link between Helicobacter pylori infection and the development of lymphoid follicles in the gastric mucosa. It is not known whether other factors may also play a role. The aim of this study was to investigate the role played by the host with peculiar immunogenic disorders, in the presence or absence of a known antigenic stimulus such as H. pylori. For this, we studied patients with autoimmune thyroid diseases. METHODS: Thirty patients with autoimmune thyroid diseases and 30 dyspeptic patients without a history of thyroid disorders (as control group) underwent upper endoscopy. Lymphoid follicles and H. pylori status were assessed by histopathologic and enzymatic analysis. RESULTS: Organized mucosa-associated lymphoid tissue was found in 73.3% of the patients and in 33.3% of control group. Lymphoid follicles were found in 87.5% of the H. pylori-positive patients and in 57.1% of the H. pylori-negative patients (P = NS). In the control group these follicles were present in 50% of H. pylori-positive subjects and in 14.3% of those who were H. pylori-negative. CONCLUSIONS: lYMPHOID follicles in the gastric mucosa are common in autoimmune thyroid diseases. Besides H. pylori infection, other factors (environmental, unknown infectious agents) or mechanisms related to the underlying disease may play a causal role.

Total thyroidectomy for benign thyroid disease.

OBJECTIVES/HYPOTHESIS: The use of total thyroidectomy in thyroid cancer treatment is not unanimous, and it is even more controversial when this procedure is advocated for benign diseases. On the other hand, the complication risk may have an increase up to 20 times in repeat operations for recurrence. The objective of the study was to evaluate the use of total thyroidectomy in benign diseases, multinodular goiter, and Graves disease to justify the authors' preference. STUDY DESIGN: Retrospective study of use of total thyroidectomy in benign diseases. METHODS: Retrospective study of 1789 patients who underwent thyroidectomies from June 1990 to December 2000. Indication, extension of thyroidectomy, cancer incidence, and complications were analyzed. RESULTS: Total thyroidectomy was performed in 81.19% of 456 patients with nontoxic multinodular goiter, 93.93% of 33 with toxic multinodular goiter, 93.93% of 66 with recurrent multinodular goiter, and 49.18% of 122 with Graves disease. Thyroid cancer was found in 16.62%, 9.09%, 3.03% and 5.73% of patients, respectively. Transitory and permanent hypoparathyroidism, hematoma requiring surgical intervention, and transitory and permanent recurrent laryngeal nerve injury occurred in 12.27%, 1.61%, 0.26%, 1.88%, and 0.35% of the patients undergoing total thyroidectomy, respectively. Permanent complications of total thyroidectomy for nontoxic multinodular goiter and Graves disease were similar to nontotal thyroidectomy. Use of total thyroidectomy for nontoxic multinodular goiter increased from 53.33% of the patient to 81.19%, on average, with a concomitant increase of cancer diagnosis from 11.11% to 16,62%. The authors performed total thyroidectomy for all patients with Graves disease. CONCLUSION: Total thyroidectomy is the treatment of choice for multinodular goiter and thyroiditis, when there is bilateral gland involvement posterior to middle thyroid veins, and for Graves disease because it decreases the likelihood of future repeat operations for recurrent disease and thus the associated risks, when performed safely.
