Among specific diabetes subtypes secondary to pancreatopathies, hereditary hemochromatosis is an inherited disorder of iron metabolism, resulting to excessive iron overload and tissue damage in various organs. We report here the case of a man with the young-onset form of the disease and we describe his glycaemic status, before and during venesection therapy. A 25-year-old man attended our clinic in Athens, Greece, with hypogonadotropic hypogonadism due to hereditary hemochroma...

Background: Several treatment options exist after thyroid malignancy has been ruled out in patients with multinodular goiter (MG). Surgery efficiently reduces the goiter size but carries a risk of both surgical and anesthetic complications while in recent years, levothyroxine suppressive therapy has been abounded. I131 therapy is the only nonsurgical alternative; however, the effectiveness diminishes with increasing goiter size and depends on iodine sufficiency in some areas. ...

Introduction: Conventional treatment of secondary hyperparathyroidism (SHP) requires supplementation of vitamin d analogues combined with calcium however several studies have reported concerns regarding the safety of calcium supplements particularly in the long term. If vitamin d without concomitant calcium supplementation is sufficient to prompt a fall in the parathyroid hormone (PTH) is still not known with certainty. The purpose of our study was to investigate if vitamin d ...

Background: Levothyroxine (LT4-Rx) is one of the most prescribed drugs worldwide and the vast majority of patients receive long-term treatment. However, in a recent study of 291 subjects we found that 60% of this cohort were euthyroid two months after LT4-Rx discontinuation1.Aim of the study: A prospective clinical cohort follow-up study was carried out. In 688 subjects (82% females) aged 48.01±15.96 (range 17-84years) with 8.59±6.98...

Background: In the last decade, the combination of the widespread use of streptavidin-biotin technology and biotin–containing supplements (BCS) in the daily clinical practice, have led to numerous reports of erroneous hormone immunoassay results. However, there are no studies assessing the clinical and biochemical significance of that phenomenon, when treating patients with hypothyroidism. Therefore, a prospective study was designed to investigate the potential alteration...

Background: Levothyroxine (LT4) is one of the most prescribed drugs worldwide. Once started, about 90% of patients continue LT4 treatment long-term.Aim of the study: To evaluate the necessity of long-term thyroxine supplementation and to determine the prognostic factors that could identify which patients may discontinue LT4 treatment.Design and methods: LT4 replacement therapy was paused for at least six weeks in all patients conse...

Introduction: There is a great interest in the association of thyroid hormones and mood. Although it appears to be important interactions between the central regulation of mood and the thyroid axis, the effects of antidepressants and especially of selective serotonin reuptake inhibitors (SSRIs) remain ambiguous. We investigated the thyroid function in perimenopausal women suffering from depression.Material and methods: We examined 102 perimenopausal wome...

Introduction: Hot flashes and night sweating are the most common medical complaints in women during the menopausal transition and they are strongly associated with the presence of perimenopausal depression. The pathophysiology of hot flashes has not been elucidated. Peripheral vasodilation and increase in skin temperature observed in women with hot flashes might be induced by changes in brain neurotransmitters and instability in the hypothalamic thermoregulatory center due to ...

Objectives: To characterize the possible role of the osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL) system in thalassemia-related bone loss.Background: Osteoporosis represents an important cause of morbidity in patients with β-thalassemia major and its aetiology is multifactorial.Methods: Serum concentrations of OPG, RANKL, markers of bone turnover and lumbar spine bone mineral density (BMD) were mea...
