SARS-COV-2-related immune-inflammatory thyroid disorders: facts and perspectives.

Expert Rev Clin Immunol 2021 Jun 2:1-23. Epub 2021 Jun 2.

Clinic for Nuclear Medicine and Competence Centre for Thyroid Diseases, Imaging Institute of Southern Switzerland, Ente Ospedaliero Cantonale, Bellinzona, Switzerland.

: During the COVID-19 pandemic thyroid gland alteration/dysfunction has been emerged as a possible endocrine complication. The present review is focused on inflammatory and autoimmune thyroid complications triggered by SARS-CoV-2 infection by searching through databases like MEDLINE and Scopus up to April 2021.: Beside the occurrence of 'non-thyroidal illness' in severe clinical conditions, alterations of thyroid function and structure may occur during COVID-19 as a consequence of either direct or indirect effects of SARS-CoV-2 infection on the gland.

Weathering the Storm: Thyroid Storm Precipitated by Radioiodine Contrast in Metastatic Thyroid Carcinoma.

Cureus 2021 Mar 31;13(3):e14219. Epub 2021 Mar 31.

Department of Pulmonary and Critical Care Medicine, Detroit Medical Center Sinai-Grace Hospital, Detroit, USA.

Thyroid storm is an extremely rare yet life-threatening medical emergency. It results from the decompensation of undiagnosed or undertreated hyperthyroidism in the presence of an acute stressor such as trauma to the thyroid, infections, acute iodine load, withdrawal from the antithyroid medication, or surgical procedures (including thyroid surgery). Clinical features of thyroid storm include hyperthermia, tachycardia, respiratory distress, gastrointestinal and hepatic symptoms, and central nervous system dysfunction. Read More

Compressive optic neuropathy (CON) in Graves' disease caused by hypertrophy of levator and superior rectus muscles: A case report.

Medicine (Baltimore) 2021 Apr;100(14):e25062

Department of Ophthalmology, Osaka Medical College, Osaka, Japan.

Rationale: Enlargemento of the medial rectus is the most predominant factor of compressive optic neuropathy (CON) in Graves' disease. This case report indicates that CON could develop only from the hypertrophic superior levator and superior rectus (SL/SR) muscle in a patient with poorly controlled Graves' disease, and described the possible risk of FT3-thyrotoxicosis with a prominent goiter to develop the current rare case with a review of the literature.

Patient Concerns: A 66-year-old woman undergoing endocrine management of hyperthyroidism with prominent goiter visited the Department of Ophthalmology due to right-eye upper-eyelid retraction. Read More

Current approach to surgical management of hyperthyroidism.

Q J Nucl Med Mol Imaging 2021 Jun 26;65(2):124-131. Epub 2021 Jan 26.

Department of Endocrine Surgery, Third Chair of General Surgery, Jagiellonian University, Medical College, Kraków, Poland -

Hyperthyroidism is a set of disorders that involve excess synthesis and secretion of thyroid hormones by the thyroid gland, which leads to thyrotoxicosis. The most common forms of hyperthyroidism include diffuse toxic goiter (Graves' disease), toxic multinodular goiter (Plummer disease), and a solitary toxic adenoma. The most reliable screening measure of thyroid function is the thyroid-stimulating hormone (TSH) level. Read More

Moyamoya Disease Associated with Graves' Disease and Down Syndrome: A Case Report and Literature Review.

J Stroke Cerebrovasc Dis 2021 Jan 30;30(1):105414. Epub 2020 Oct 30.

Department of Neurosurgery, Nagasaki Prefecture Shimabara Hospital, 7895 Shimokawasiri, Shimabara, Nagasaki 855-0816, Japan.

Background: Moyamoya vessels are cerebral vasculopathies characterized by net-like collateral vessel formation at the cerebral basal area and stenosis of the terminal internal carotid artery, proximal middle cerebral artery, and anterior cerebral artery. A diagnosis of Moyamoya disease depends on the bilateral presence of Moyamoya vessels. Moyamoya disease associated with Graves' disease has rarely been reported to be a cause of ischemic events due to hyperthyroidism. Read More

A Review of the History of Radioactive Iodine Theranostics: The Origin of Nuclear Ontology

Mol Imaging Radionucl Ther 2020 10;29(3):88-97

Miami Cancer Research Center, Miami, USA

Studies on the first years of radioactive iodine (RAI) use in thyroid diseases have focused on hyperthyroidism. Saul Hertz's success with RAI in thyrotoxicosis fueled a seamless transition to Samuel Seidlin's investigations with RAI in thyroid cancer. These landmark events embody nuclear ontology, a philosophical foundation for the creation and existence of radio-therapeutic principles that continue to influence clinical practices today.

EGA Institute for Women's Health, Faculty of Population Health Sciences, University College London (UCL), London, UK. Electronic address:

Objective: To evaluate the ultrasound diagnostic rates of complete hydatidiform moles (CHM) and partial hydatidiform moles (PHM) in women presenting with a missed miscarriage, the clinical complications at diagnosis and the risk of gestational trophoblastic neoplasia (GTN) after surgical evacuation and to compare our findings with those of the published literature by completing a systematic review and meta-analysis STUDY DESIGN: Retrospective review of the data of 295 women diagnosed with a histologically confirmed hydatidiform moles (HM) over a 15-year period, including 128 CHM and 167 PHM.

A remarkable case of thyrotoxicosis initially caused by graves' disease followed by a probable TSHoma - a case report.

BMC Endocr Disord 2020 Aug 27;20(1):133. Epub 2020 Aug 27.

Department of Diabetes and Endocrinology, Beaumont Hospital and the RCSI, Dublin, Ireland.

Background: Graves' disease is the commonest cause of thyrotoxicosis whilst thyrotropin (TSH)-producing pituitary adenomas (thyrotropinomas, TSHomas) are very rare and account for just 1-2% of all pituitary adenomas. Coexistence of a TSHoma and Graves' disease has been very rarely reported. Here, we report a case of a patient whose initial presentation with primary thyrotoxicosis due to Graves' disease, was subsequently followed by a relapse of thyrotoxicosis due to a probable TSHoma.

Front Endocrinol (Lausanne) 2020 6;11:523. Epub 2020 Aug 6.

Department of Endocrinology and Metabolism, Institute of Endocrinology, The First Hospital of China Medical University, Shenyang, China.

Thyroid stimulating hormone (TSH) secreting pituitary adenoma (TSHoma) is a rare cause of hyperthyroidism.
