Vitamin D deficiency is a common health problem worldwide. Many parts of the human eye, including epithelium cornea, lens, ciliary body, and retinal pigment epithelium, as well corneal endothelium, ganglion cell layer, photoreceptors, contain vitamin receptor (VDR). Dry eye also problem. An adequate tear film required for maintaining function eye. Tear hyperosmolarity considered to be cause ocular surface inflammation, symptoms, tissue damage. It well-documented that has an anti-inflammatory...

Background/aim: In Graves' disease (GD), an autoimmune disease, antibodies targeting the TSH receptor cause production of excessive amounts thyroid hormone. A significant association has been reported between low 25(OH) Vitamin D3 (VitD) levels and various disorders. Therefore, this study aimed to investigate effects VitD deficiency replacement therapy on laboratory clinical parameters in GD patients.Methods:Fourty 37 healthy control patients were included study. Patients with divided into...

SUMMARY Although the development of subacute thyroiditis (SAT) following viral infections is well-documented, actual mechanism has not been clearly elucidated. The occurrence SAT after vaccination reported in several case series and possible mechanisms such as molecular mimicry due to exposure proteins and/or abnormal reactogenicity by adjuvants have implicated. We describe two cases who developed three days messenger RNA vaccine against COVID-19 (Pfizer-BioNTech®) six inactivated [...]
