Introduction: In our country, some health institutions are allowed to constitute additional service buildings/centers in order to increase the accessibility to outpatient services and decrease the crowdiness in hospitals. We aimed to investigate the satisfaction of the patients evaluated in our endocrinology and metabolism diseases center-ENDOOTEM (Endocrinology-Nuclear Medicine-Diabetes-Obesity-Osteoporosis-Thyroid Diagnosis and TreatmentCenter)- which serves as a part of our...

Introduction: Phaeochromocytomas (PHEO) are diagnosed with classic findings and symptoms but biochemical confirmation must be made. Either urinary or plasma chatecholamines and metanephrines can be used for biochemical evaluation. Normal values rule out the diagnosis, whereas fourfold increase above the upper limit of normal confirm the diagnosis. But value of borderline or less than fourfold elevations in the diagnosis is not clear. We aimed to determine the urinary fractiona...

Introduction: Major factor that modulates the PTH secretion is serum Ca level. Paratyhyroid gland also receives direct autonomic innervation. To date, measurement of several hormones such as cortisol,prolactin, renin and aldosteron were found to be affected by changing the posture from recumbent to the upright position. In the present study, we aimed to investigate postural change of PTH in normal individuals and patients with primary hyperparathyroidism (PHPT).<p class="a...

Introduction: Fine-needle aspiration (FNA) is a simple, the most cost-effective, less invasive and a commonly used diagnostic tool for evaluating thyroid nodules. Recent times a tech-nique called fine-needle sampling non-aspiration (FNNA) or fine-needle capillary thyroid biopsies (FNC) has been more preferred. This technique prevents the use of suction so there is no aspiration crush and there-fore nondiagnostic outcomes are reduced. The aim of this prospective study was to co...

Background: Alstrom syndrome is a rare autosomal recessive genetic disorder characterised by vision loss, hearing loss, childhood obesity, insulin resistance and hyperinsulinemia, type 2 diabetes, hypertriglyceridemia, cardiomyopathy, and progressive pulmonary, hepatic, and renal dysfunction. Hyperinsulinemia develops early, and pancreatic islets show beta-cell proliferation, thus suggesting that both insulin resistance and increased insulin secretion might contribute to gluco...

Background: Although high levels of calcitonin suggest neoplastic proliferations such as medullary thyroid carcinoma, C cell hyperplasia and some neuroendocrine tumors, systemic diseases and drugs may also elevate calcitonin. Although calcitonin is not as effective as PTH, it has got a role in calcium hemoastasis. Supraphysiological calcitonin level can lead to hypocalcemia.Case presentation: A 57-year-old male patient was diagnosed with epilepsy with co...

Pituitary adenomas which co-secrete GH and TSH accounts for <0.2% of all adenomas of the pituitary. Symptoms of hypertyroidism are usually masked by clinical manifestations of acromegaly. Here, we have reported the result of the primary one year long medical therapy in a case who was diagnosed to have adenoma co-secreting GH and TSH.Case: Seventy-years-old female patient has admitted with the complaints of excessive sweating, enlargement of hands and...

Introduction: Nowadays, ultrasonography (USG) is being used very commonly and indispensably for diagnosing thyroid diseases. Heterogeneous appearance of thyroid parenchyma is associated with positivity for thyroid autoantibody and hypofunctioning of thyroid gland. On the other hand, it is not determined whether thyroid parenchyma appearing totally of normal ecogenity on USG is related to presence normal thyroid function tests or otherwise. The objective of our study was evalua...

Aim: Percutenous ethanol injection (PEI) is a minimally invasive method which can be preferred in treatment of cystic thyroid nodules. We have presented our cases of PEI below.Material and methods: We have performed PEI to 8 patients in our clinic. We have made ultrasound guided fluid aspiration from the cysts which were confirmed to be benign. We have injected ethanol (98%) into the pouche of the cyst in an amount that is 20–40% of the cystic fluid...

Introduction: Coexistence of type 1 diabetes mellitus (DM) and autoimmune thyroid diseases was shown in previous studies. Thyroid dysfunctions and thyroid autoantibody positiveness were reported in 23–25 and 27–44% of patients with type 1 DM, respectively. In recent years, thyroid ultrasonography (US) is widely used to diagnose autoimmune thyroid diseases with regard to its ability to define thyroid morphology and echogenity. In this study, we aimed to evaluate thyro...
