It has been hypothesized that prolactin may act on the immune system. It has been suggested that prolactin may act on the immune system and may be implicated in the pathogenesis of autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, as mild hyperprolactinemia has been found in patients with systemic lupus erythematosus.We tested the hypothesis that prolactin may act on the immune system and induce the development of autoim...

Low vitamin D levels have been found in patients with diabetes mellitus type 2 and have been correlated with poor glycemic control. There are observations suggesting that vitamin D levels may be low in obesity.The aim was to study vitamin D levels in obese individuals.The levels of 25(OH)D3 were measured in 30 obese individuals aged 42.67 years (mean), range 27–64, BMI 35.49 (mean), range 30–46 and 37 control s...

Thyroid disease epidemiology has changed recently. This change may be related to changes in the iodine status of the environment. Iodine deficiency was observed in earlier years in Greece. The progression of multinodular goiter to hyperthyroidism was frequently observed. Nowadays, the development of autoimmune thyroiditis is frequently observed in patients with simple or nodular goiter. This development may be related to the proinflammatory action of iodine, iodine being nowad...

Vitamin D is synthesized in the skin. Low vitamin D levels have been observed in African Americans. However, the relationship between vitamin D and skin color has not been completely evaluated.The aim was to study the relationship between dark skin color and vitamin D levels in healthy individuals.Vitamin D (25(OH)D3) levels were measured in 15 dark skinned individuals. All subjects were immigrants, having migrated to Gr...

Nodular hyperplasia of the adrenal as a cause of Cushing’s syndrome is rare. Adrenal tumors, frequently causing syndromes such as hyperaldosteronism due to autonomous hormone secretion, have been described in patients with renal cysts. The aim was to describe the case of a female patient with diffuse adrenal hyperplasia, subclinical Cushing’s syndrome and renal cysts.A female patient aged 69 years presented with hyperplasia of the right adrenal...
