A Thyrotoxicosis Surprise: Jod-Basedow Phenomenon Following IV Contrast Administration.

Cureus 2022 May 4;14(5):e24742. Epub 2022 May 4.

Endocrinology, Brookdale University Hospital Medical Center, Brooklyn, USA.

Jod-Basedow phenomenon (JBP) is a rare thyrotoxic condition due to increased exogenous iodine exposure, also known as iodine-induced hyperthyroidism (IIH). Historically JBP was typically seen in iodine-deficient patients when exposed to increased amounts of iodine. However, in today's era, the most common cause of JBP is exposure to iodinated contrast media commonly used in various radiological examinations and interventional procedures, resulting in massive iodine exposure.

J Pak Med Assoc 2022 Mar;72(3):560-563

Department of Radiology, MINAR Cancer Hospital, Multan, Pakistan.

Pyrexia of unknown origin (PUO) is a challenging entity in medical practice from a diagnostic point of view. Sub-Acute Thyroiditis (SAT), that is an inflammatory condition of thyroid, self-limiting and easily treatable, is a very rare cause for PUO with a few published cases and unfortunately not considered in routine for the differential diagnosis (DD) of PUO. Usually, it presents with mild thyrotoxicosis signs and symptoms, painful goiter, and rarely with cervical Lymph adenopathy. Read More

Q J Nucl Med Mol Imaging 2022 Jun 15;66(2):86-92. Epub 2022 Feb 15.

Department of Oncology and Nuclear Medicine, University Hospital Center Sestre Milosrdnice, Zagreb, Croatia.

Nuclear medicine methods were introduced in the 1940s for thyroid disease diagnosis and therapy. They is still a crucial part of thyroid nodules work-up. Thyroid imaging with iodine or iodine-analog isotopes is widely employed in patients with thyrotoxicosis and remains the only examination able to prove the presence of autonomously functioning thyroid tissue, which excludes malignancy with a high probability.

Thyroid functional and molecular imaging.

Presse Med 2022 Feb 4;51(2):104116. Epub 2022 Feb 4.

Department of Nuclear Medicine, Cochin Hospital, Assistance Publique Hôpitaux de Paris, DMU Imagina, University of Paris France.

Radioiodine uptake (RAIU) test with iodine-123 (Na[I]I) or iodine-131 (Na[I]I) enables accurate evaluation and quantification of iodine uptake and kinetics within thyroid cells. Thyroid Scintigraphy (TS) employing Na[I]I or Tc-pertechnetate (Na[Tc]TcO) provides information regarding the function and topographical distribution of thyroid cells activity, including detection and localization of ectopic thyroid tissue. Destructive thyrotoxicosis is characterized by low RAIU with scintigraphically reduced radiotracer activity in the thyroid tissue, while productive thyrotoxicosis (i. Read More

Edinburgh Centre for Endocrinology and Diabetes, Royal Infirmary of Edinburgh, Edinburgh, UK

Subacute thyroiditis following vaccination is an uncommon presentation of thyrotoxicosis. As the world undertakes its largest immunisation campaign to date in an attempt to protect the population from COVID-19 infections, an increasing number of rare post vaccine side effects are being observed. We report a case of a middle-aged woman who presented with painful thyroid swelling following the second dose of the COVID-19 mRNA vaccine BNT162b2 (Pfizer-BioNTech) with clinical, biochemical and imaging features consistent with destructive thyrotoxicosis.

Graves' disease coexisted with resistance to thyroid hormone: a case report.

J Med Case Rep 2021 Sep 25;15(1):473. Epub 2021 Sep 25.

Department of Endocrinology, Diabetology and Metabolism, Toyama Prefectural Rehabilitaion Hospital and Support Center for Children with Disabilities, 36 Shimo-Iino, Toyama-shi, Toyama, 931-8517, Japan.

Background: Resistance to thyroid hormone is a rare autosomal dominant disorder characterized by reduced responsiveness to thyroid hormone and can cause syndrome of inappropriate secretion of thyroid stimulating hormone. Although Graves' disease is a common autoimmune thyroid disorder, the coexistence of these two diseases is extremely rare and makes the diagnosis and treatment complicated, leading to the delayed diagnosis of resistance to thyroid hormone. We describe the case of a Japanese man with resistance to thyroid hormone coexisting with Graves' disease, in which the correct diagnosis of resistance to thyroid hormone was delayed by masking of the signs of syndrome of inappropriate secretion of thyroid stimulating hormone, with final diagnosis 30 years after the initial treatment for Graves' disease.

Diagnostic Utility of Mean Peak Systolic Velocity of Superior Thyroid Artery in Differentiating Graves' Disease from Thyroiditis.

Indian J Radiol Imaging 2021 Apr 27;31(2):311-317. Epub 2021 Jul 27.

Department of Radiodiagnosis, Srirama Chandra Bhanja Medical College and Hospital, Cuttack, Odisha, India.

Differentiating Graves' disease from thyroiditis can be at times clinically challenging. The gold standard test (thyroid nuclear imaging scan) is expensive, not routinely available, and has radiation exposure. Color Doppler ultrasonography of thyroid represents a suitable alternate which can be used for differentiating these conditions by studying thyroid blood flow parameters. Read More

Hyperthyroidism associated with - a case report and review of literature.

Gynecol Endocrinol 2021 Dec 13;37(12):1143-1150. Epub 2021 Aug 13.

Department of Gynecological Endocrinology, Poznan University of Medical Sciences, Poznan, Poland.

Background: Hyperthyroidism is a state characterized by elevated serum level of thyroid hormones: thyroxine (T4) and triiodothyronine (T3). This is mainly related to the condition and functioning of the thyroid gland. In 60-80% of cases elevation of these hormones are caused by Grave's disease. Read More

Inappropriate use of thyroid ultrasound: a systematic review and meta-analysis.

Endocrine 2021 11 11;74(2):263-269. Epub 2021 Aug 11.

Mayo Clinic, Knowledge and Evaluation Research Unit, 200 First Street Southwest, Rochester, MN, 55905, USA.

Purpose: Nearly half the cases of thyroid cancer, a malignancy rapidly rising in incidence within the United States, are attributable to small and asymptomatic papillary thyroid cancers that will not increase mortality. A primary driver of thyroid cancer overdiagnosis is ultrasound use. It is therefore valuable to understand how inappropriate use of thyroid ultrasound is defined, analyze the current evidence for its frequency, and identify interventions to lessen misuse. Read More
