Introduction: The differential diagnosis between Graves’ disease (GD) and gestational transient thyrotoxicosis (GTT) is difficult in the absence of history and clinical features of GD. In this study, we aimed to determine the role of peak systolic (PSV) and end-diastolic velocities (EDV) of the right and left inferior thyroid arteries (ITA) as measured by color-flow Doppler ultrasonography (CFDUSG) for discriminating GTT from treatment naive GD.Meth...

Background: Obesity and diabetes mellitus (DM) are the features of Cushing’s disease (CD). Studies indicated different frequencies of CD among obese, type 2 DM patients. The frequency of CD among obese, type 2 DM have’nt been studied in Turkey. Therefore, we aimed to assess the frequency of CD among obese (BMI>30 kg/m2) type 2 DM patients that had not classical morphological findings of CD.Patients and methods: Two hundred consec...

Background: Acromegaly is a multi-systemic dysfiguring disease caused by pituitary GH secreting tumour. Pituitary surgery, medical treatment with somatostatin analogues and radiotherapy have been cornerstone in the management of acromegaly. However, all these treatment modalities do not provide sufficient disease control especially in patients with macroadenomas.Objective: To evaluate the follow-up outcomes and remission rates of acromegaly patients....

ObjectiveScanty data about glucose metabolism, hypertension and metabolic syndrome (MS) have been reported in Paget’s disease of bone (PDB) to be related with increased cardiovascular mortality. We aimed to determine prevalence of metabolic syndrome in PDB and to determine the relationship between metabolic syndrome and bone-specific alkaline phosphatase levels.Patients and methodsTwenty three patients w...

Background: Currently, multiple treatment options are available for the treatment of acromegaly. However, cure is obtained only in 50% of patients with macroadenomas after surgery. Persistent tumor enlargement occur in 2.2% of the patients treated with somatostatin analogs and in 1.6–2.9% of the patients treated with pegvisomant. The nuclear antigen Ki-67 is related to growth potential and is also a major prognostic indicator for pituitary adenomas. Studies demonstrated t...

Aim: Metabolic syndrome rates have been studied especially in adrenal gland secreting cortisol and studies on nonfunctional adenomas are limited. In this study, we investigated metabolic parameters and metabolic syndrome frequency in non-functional adrenal adenomas (NFA).Materials and methods: In our study, 55 patients (15 men (27.3%), 40 women (72.7%) who were diagnosed incidentally, unilateral or bilateral localized, hormone-inactive, and with adenoma-...

Introduction: Hyperkalemia due to zona glomerulosa (ZG) insufficiency is generally transient and mild for patients with aldosterone-producing adenoma (APA) after adrenalectomy. We report here a case with prolonged ZG insuffiency requiring long-term mineralocorticoid replacement (MR) therapy.Case report: A 45-years-old female with hypertension and hypokalemia admitted to outpatient clinic with incidentally detected right adrenal adenoma (3 cm) showing sig...

Introduction: Hypogonadism persisting in man with macroprolactinoma requires exogenous testosterone replacement therapy (TRT). But TRT may cause secondary elevations of prolactin. We report here a case of macroprolactinoma and hypogonadotropic hypogonadism with persistently high prolactin level after initiating TRT.Case report: A 28 year-old male was admitted to outpatient clinic with complaints of headache, low libido and blurred vision on left eye for ...

Purpose: To determine the relationship between grade of diabetic retinopathy and serum vitamin D levels in diabetic patients.Materials and methods: A total of 173 diabetic patients consisting of patients without retinopathy (n=67), patients with non proliferative diabetic retinopathy (NPDRP group n=47), patients with proliferative diabetic retinopathy (PDRP group n=59) was included in the study. Age and sex matched 55 healthy s...

Introduction: Ectopic ACTH syndrome (EAS) is a rare cause of Cushing’s syndrome. EAS is most frequently caused by bronchial carcinoid tumor or small cell lung cancer. Medullary thyroid carcinoma (MTC) is a rare source of EAS, as reported in this case.Case report: A 65-years-old-female with back pain and weight gain referred to our outpatient clinic with determined signs and symptoms of hypercortisolism. She had arterial hypertension, her sister had ...
