Thyroglobulin is a glycoiodoprotein that is produced by thyroid follicular cells; it is stored in follicles in structures known as colloids. The main function of this protein is to stock the hormones triiodothyronine (T3) and thyroxine (T4) until the body requires them. This study aims to demonstrate that infrared spectral imaging with appropriate multivariate analysis can reveal biochemical changes in this glycoprotein. The results achieved herein point out biochemical differences in the colloid samples obtained from normal and goiter patients including glycosylation and changes in the secondary conformational structure. We have presented the first spectral histopathology-based method to detect biochemical differences in thyroid colloids, such as TG iodination, glycosylation, and changes in the secondary structure in normal and goiter patients. The observed changes in the colloids were mainly due to the alterations in amide I and amide II (secondary conformation of proteins) and there is a correlation with different glycosylation between normal and goiter tissues.

Objective: This study aimed to determine whether a relationship exist between pre-therapy 25-hydroxyvitamin D levels and the remission/negative conversion rates of thyrotropin receptor antibody (TRAB) during treatment in patients with newly diagnosed Graves' disease (GD).
Methods: 171 patients were included from the Endocrinology Department of the First Affiliated Hospital of Fujian Medical University in March 2013 to April 2016. Ninety-five patients of them were diagnosed at our hospital but transferred to local hospitals for treatment.
Introduction: Atrophic autoimmune thyroiditis (AAT) is a form of autoimmune hypothyroidism characterized by the absence of a goiter. Thyroid stimulation blocking antibody (TSBAb) has been detected in a subset of pediatric AAT cases. Although the disappearance of TSBAb has been linked to the recovery of thyroid function in adult AAT cases, similar outcomes have not been documented in pediatric cases.

Gaucher disease (GD), the most common ultra-rare metabolic disorder, results from lipid accumulation. Systemic inflammation, cellular stress, and metabolic dysfunction may influence endocrine function, including the thyroid. This study evaluated thyroid function and morphology in 60 GD patients, alongside carbohydrate and lipid metabolism.

Background: Microwave ablation is a new, minimally invasive technique for the treatment of thyroid nodules. Hyperthyroidism due to destructive thyroiditis is a known risk of microwave ablation, though it occurs in only a minority of cases. We report a rare case of a patient diagnosed with Graves' disease nearly six months after undergoing microwave ablation of a thyroid nodule.
