Background: There is some evidence suggesting an interaction between renin-angiotensin-aldosterone system and parathyroid hormone (PTH). Decreased aldosterone levels after parathyroidectomy have been reported in patients with primary hyperparathyroidism (PHPT). Recently, most of the diagnosed patients with PHPT are mild or asymptomatic. Our aim was to investigate plasma aldosterone and renin concentrations in patients with asymptomatic PHPT.Methods: Thir...

Objective: Cushing’s syndrome (CS) is related to diabetes mellitus, dyslipidaemia, hypertension, and obesity, which lead to cardiovascular disease (CVD). CVD is the major cause of mortality and morbidity in CS. The aim of our study was to investigate CVD risk markers, such as asymmetric dimethylarginine (ADMA), lipoprotein-associated phospholipase A2 (Lp-PLA2), highly sensitive C-reactive protein (hsCRP), homocysteine, lipid levels, ankle-brachial index (ABI), and carotid...

Introduction: 46 XX male syndrome generally presented as hypogonadotrophic hypogonadism.Case report: A 39-year-old man was referred to our clinic with a pituitary mass. He had a history of pituitary adenoma of 45×28×40 mm size which was found after his admission with right-sided vision loss at 2006. The hormonal analyses showed hypogonadotrophic hypogonadism without any excess hormone levels. A transcranial pituitary adenomectomy was performed....

Introduction: Werner syndrome (WS) is an autosomal recessive disease characterized by premature aging, skin changes, gray hair, alopecia, muscle atrophy, osteoporosis, and cataracts and has a high frequency of association with rare neoplasms. In addition, some endocrinological abnormalities were manifested in this rare disease, such as hypogonadism, diabetes mellitus, hyperlipidemia. Atrophic changes of organs and systems such as skin, brain and genital organs were reported. H...

Introduction: Hashimoto’s thyroiditis (HT) is common autoimmune thyroid disorder and is predominantly the clinical expression of cell-mediated immunity leading to destruction of thyroid cells. Vitamin D plays a role in the regulation of immunity and cell proliferation. So, do the serum levels of vitamin D reduced in HT?Methods: We examined the medical records of the ‘Thyroid policlinic’ patients with or without HT. Vitamin D, thyroid autoa...

Endocan has been suggested as a marker for endothelial dysfunction. Some evidence exists that Graves’ disease may be associated with impaired endothelial function. The aim of the study was to evaluate serum endocan, endothelial growth factor (VEGF) and carotid intima media thickness (CIMT) in patients with Graves’ disease. Thirty one newly diagnosed patients with Graves’ disease and 31 healthy volunteers with similar age and sex were examined. Serum endocan, VEG...

Aim: Sleep disturbances are widespread and closely associated with pituitary diseases, even those under long-term therapeutic management. The aim of this study was to investigate sleep quality, depression, anxiety, and physical activity in patients with non-functioning pituitary adenoma (NFPA) and determine the factors that might be associated with decreased quality of sleep.Method: Eighty-two patients with NFPAs and 82 age- and gender-matched control su...

Metastatic infiltration of the adrenal glands is a common finding of malignancies, but few case reports showed primary adrenal insufficiency being the presenting manifestation of underlying malignant tumors. Here, we report a case of adrenal insufficiency secondary to metastases from lung adenocarcinoma.A 69-year-old man was admitted to emergency department with weakness, altered mental status, hypotension, fever and weight loss. He had 100 pack-year his...

Idiopathic granulomatous hypophysitis is a very rare inflammatory disease of the pituitary gland. Primary hypophysitis represents a difficult diagnostic challenge because it can imitate pituitary adenomas clinically and radiologically. The diagnosis is usually made histologically by hypophysectomy. We herein present a rare case of idiopathic granulomatous hypopysitis diagnosed primarily by pituitary biopsy.Case: A 50-year-old female patient presented wit...

Cardiovascular deleterious effects of short term hypothyroidism are not well known. We aimed to investigate proprotein convertase subtilisin/kexin type 9 (PCSK9), soluble lectin-like oxidized LDL receptor 1 (sLOX-1) and ankle brachial index (ABI) in patients with thyroid cancer with short term overt hypothyroidism due to thyroid hormone withdrawal (THW). Twenty-one patients who require radioactive iodine (RAI) ablation or RAI scan and thirty-six age, sex, BMI similar euthyroid...
