Objective: Gestational diabetes mellitus (GDM) is strongly associated with maternal obesity. Omentin-1 is secreted from the adipose tissue and enhances insulin action. Circulating levels are inversely correlated with body weight, decreased in type 2 diabetes. Pre-existing maternal obesity has been shown to be associated with lower omentin-1 expression in placenta, adipose tissue and maternal plasma. In our previous study, we had shown that plasma omentin-1 level is decreased i...

Objective: Irisin is a novel adipomyokine that regulates the differentiation and phenotype of adipose tissue. It induces an increase in total body energy expenditure, improves insulin sensitivity, and glucose tolerance. It showed that the levels of irisin are low in obese, diabetic and impaired glucose tolerance patients. However, the information of the levels of circulating irisin in gestational diabetes mellitus (GDM) is controversial. In this study, we investigated i) the l...

Introduction: The cases of paragangliomas (PGLs) mimicking thyroid nodules were also reported in literature rarely. We will present a case of PGL (a carotid body tumor) that we initially evaluated as a thyroid nodule, and then diagnosed as a PGL.Case report: A 74-year-old woman was admitted due to a mass in the right side of neck growing rapidly within the last 1 month. Physical examination revealed a hard and painless mass with smooth surface, extending...

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....

Pregnancy in active acromegaly at reproductive age is very rare occurrence due to hyperprolactinemia, hypogonadism and side effects of treatment of acromegaly. Only a few reports were described in medical literature by now.We report a 31-year-old woman ongoing active acromegaly despite who received Octeatide LAR 30 mg treatment monthly for the control of GH and IGF1 excess until realized her pregnancy. A GH secreting pituitary macroadenoma (tumor size 2 ...

Lingual thyroid is an abnormal formation appearing as the result of a deficient descent during embryological development of the thyroid gland through the thyroglossal duct to its normal pretracheal location, and it is a rare embryological aberration. A 19 years old woman was admitted to with foreign-body-feeling, dysphonia, hoarseness, constipation. Examination showed a spherical, red fleshy and smooth contoured mass rat back of the tongue. Thyroid scan with technetium 99 m re...

Objectives: Evaluation of the HPA axis is still a big challenge. This study was performed to compare 1 μg ACTH, 250 μg ACTH and glucagon tests for evaluation of HPA axis in healthy male and female subjects with different ages.Materials and methods: This study was carried out on 57 healthy individuals (29 men, 28 women) between 20 and 70 years of age (the number and gender of the subjects are approximately equal for each decade). Low dose short ...

‘Nondippers’ are individuals with absence of anticipated nocturnal decrease in blood pressure (BP) and increased incidence of target organ damage. The pathogenesis of nondipper hypertension is not clear at present. We aimed to investigate the effect of overt and subclinical hypothyroidism on the development of nondipper blood pressure pattern via 24-hour ambulatory blood pressure monitoring. One hundred and nine normotensive patients with overt and subclinical hypoth...

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...

Objective: Serum total sialic acid(SA) concentration is assessed as an up to date risk indicator of atherosclerosis and cardiovascular diseases.Methods: It was aimed to investigate about how SA levels are effected in overt or subclinical hypothyroidism (SH) and how it’s associated with other atherosclerosis risk factors because there is no study about these topics, though SA is intensively studied in recent years.Patients: Six...
