BACKGROUND: Thyroid-associated orbitopathy (TAO) causes inflammatory fibroproliferation of periocular connective tissues. We compared adipose tissue-derived stem/stromal cells (ADSCs) from three adipose depots of each patient with TAO on mesenchymal, myofibrogenic, adipogenic properties and associated hyaluronan (HA) synthesis. METHODS: ADSCs were generated from periocular (eyelid, orbital) and subcutaneous (abdominal) adipose tissues of three patients with TAO...

Selenium (latin Selenium) is a micronutrient embedded in several proteins. In adults, the thyroid is the organ with the highest amount of selenium per gram of tissue. Selenium levels in the body depend on the characteristics of the population and its diet and geographic area. In the thyroid, selenium is required for the antioxidant function and for the metabolism of thyroid hormones. The literature suggests that selenium supplementation of patients with Hashimotos thyroiditis is associated with a reduction in antithyroperoxidase antibody levels...

Impression cytology (IC) is a technique which permits the retrieval of the outermost layer of ocular surface cells via the use of various types of filters. It is a minimally invasive method of evaluating human conjunctival epithelial cell morphology in the diagnosis of dry eye disease, a common and distressing disorder associated with ageing, contact lens wear, autoimmune disorders and refractive (LASIK) surgery. IC may also be utilized in the diagnosis of other ocular diseases, such as keratoconus and thyroid orbitopathy...

Several antineoplastic treatments have been responsible for thyroid dysfunction and thyroid eye disease. Min, Vaidya, and Becker (2011) reported a case of euthyroid Graves orbitopathy after treatment with ipilimumab with the patient displaying proptosis and myositis in the setting of normal thyroid function tests and elevated thyroid antibodies. The authors report a case of a 76-year-old woman who developed right upper lid retraction and proptosis after 2.5 years of treatment with lenalidomide for multiple myeloma...

Dysthyroid optic neuropathy (DON) is the commonest cause of blindness in thyroid associated orbitopathy (TAO). While diagnosis remains clinical, objective tests for eyes with early or equivocal findings are lacking. Various electrophysiological studies (EPS) have been reported, yet the types and parameters useful for DON remain inconclusive. We performed a systematic literature search in MEDLINE, EMBASE and the Cochrane databases via the OVID platform up to August 20, 2017. 437 records were identified for screening and 16 original studies (1327 eyes, 787 patients) were eligible for review...

To date, Thyroid-Associated Orbitopathy (TAO), an autoimmune inflammatory disease affecting the eye, remains poorly characterised and its diagnosis challenging. The aim of this study was to investigate the tears of the TAO patients in order to identify potential biomarkers. Two independent quantitative Tandem Mass Tag™ 6-plex experiments were done. After in-solution digestion and isoelectric fractionation, the 12 fractions were analysed with a LTQ Orbitrap Velos coupled to a liquid chromatography. Raw files were searched against Swiss-Prot-AC database using Proteome Discoverer software, with a false discovery rate of 1% at peptide and protein levels...

Orbital decompression is an effective and invaluable procedure for addressing some of the chronic manifestations of Graves' Ophthalmopathy (GO) such as exophthalmos and orbital congestion. Fat-removal orbital decompression (FROD) started to gain popularity after its introduction in the late 20th century. Among the therapeutic armamentarium of techniques and approaches available for orbital decompression, FROD has proven its efficacy and safety in addition to its ability to reduce proptosis in a relatively predictable manner...
