Evaluation of a Clinical Pathway for Thyroid Nodular Disease: Timings and Delays in the Diagnosis and Treatment of Thyroid Cancer.

Background: Due to the high prevalence of nodular thyroid disease in the general population and the need to rule out malignant tumours, a clinical pathway for nodular thyroid disease was created at our tertiary-level hospital. Our study aimed to quantify timings and delays in diagnosis and treatment in this clinical pathway, specifically for patients who were diagnosed with thyroid cancer.

Methods: A retrospective review was conducted of patients who were newly diagnosed with thyroid cancer and who had been previously evaluated in the clinical pathway for nodular thyroid disease at our institution during 2015-2017.

Pathological thyroid findings in amiodarone-induced thyrotoxicosis.

Amiodarone (AMD) is a class III antiarrhythmic drug whose chronic or high dosage administration alters the tests of thyroid function. AMD is also associated with hypothyroidism or thyrotoxicosis. Total thyroidectomy is an efficient treatment of AMD-induced thyrotoxicosis in cases resistant to medical therapy, worsening of cardiac function and/or severe thyrotoxicosis.

Merkel cells of human oral mucosa express the pluripotent stem cell transcription factor Sox2.

Merkel cells are neuroendocrine cells associated to a neural sensitive ending and localized primarily in the epidermis, although they are also found in oral mucosa. Sox2 or SRY-box2 is a key transcription factor important in the maintenance of embryonic neural crest stem cell pluripotency. Sox2 has been described in Merkel cells of skin and in Merkel cell carcinomas, but not specifically in oral Merkel cells.
