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...

Mixed medullary-follicular carcinomas (MMFC) of the thyroid are rare tumors which represents <0.15% of all thyroid tumors showing the morphological and immunochemical properties of both parafollicular and follicular cell lineages. Cases were immunoreactive for both calcitonin and thyroglobulin.Case 1: A 25-year-old female patient referred us for evaluation of a thyroid mass located on the left lobe. Ultrasonography (US) revealed 38 mm solid isoechoic...

Immune supressive patients due to any cause (disease, medication, etc.) rarely have autoimmune diseases. In this presentation, two patients diagnosed with Graves’ disease and subacute thyroiditis while taking cyclosporine therapy will be discussed.Case 1: A 47-year-old female patient applied with weight loss, sweating and tremor. She had been on cyclosporine therapy for 3 years because of hypoplastic anemia. In laboratory tests; TSH: 0.005 uIU/ml (0...

Well-known environmental factors which can lead to type 1 diabetes are viral infections, vaccines, diet, exposure to cow milk in infancy, vitamin D deficiency, drugs, maternal age, preeclampsia and low birth weight. Isotretinoin is an effective drug for acne treatment. It can cause dyslipidemia, elevated liver enzymes, insulin resistance and type 2 diabetes. Our case is type 1 diabetes developed after the use of isotretinoin and represented with diabetic ketoacidosis.<p cl...

Background: Generously supported by IPSEN)-->In this study we have aimed to calculate the QT dispersion in acromegaly patients and reveal its correlation with GH and IGF1.Materials and methods: Forty-one acromegaly patients were enrolled in the study. Another 41 patients with similar age, sex and comorbid disease distrubition have constituted the control group. We have evaluated the electrocardiograms (ECG) of ...

Riedel thyroiditis is a rare chronic inflammatory disease of the thyroid. It is characterized by replacement of normal parenchyma with dense fibrotic tissue. Peripheral tissues might also be affected and this may cause airway obstruction, dysphagia, recurrent laryngeal nerve palsy and hypoparathyroidism. We report a patient with toxic adenoma previously treated with radioactive iodine and histopathologically confirmed Riedel thyroiditis.Case: A 61 years ...

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...

Introduction: Polycystic ovary syndrome (PCOS) is a common disorder characterized by chronic anovulatory oligo-amenorrhea and signs of hyperandrogenism. In this study, we aimed to determine prevalence of thyroid nodules and autoimmune thyroid diseases in patients with PCOS.Methods: Patients diagnosed with PCOS in our endocrinology clinic were included in the study. In patients with irregular menses and/or hirsutism, the diagnosis of PCOS was made by high...

Aim: Thyroid pyramidal lobe and thyroglossal duct cysts were reported to be associated with increased risk of thyroid cancer. In this study, we aimed to evaluate ultrasonography (US) guided fine needle aspiration biopsy (FNAB) cytology results of pyramidal lobe and thyroglossal duct cysts.Material and methods: Patients with pyramidal lobe and thyroglossal duct cysts detected in US were included. Thyroid functions, thyroid autoantibodies, Tc 99m thyroid s...

Introduction: Increased exposure to sunlight and high serum levels of Vitamin D were reported to relate with decreased risk of various cancer types, such as prostate, breast and colon. Vitamin D receptor and 1α-hydroxylase expression were shown in papillary thyroid carcinoma. In this study, we aimed to evaluate serum 25-OH vitamin D levels in patients with benign and malignant thyroid nodulesMethods: Patients admitted to our thyroid clinic were recr...
