Aim: Our aim was to investigate the frequency of isolated maternal hypothyroxinemia (IMH) at gestational diabetes mellitus (GDM)Material and method: Fifty women with GDM aged between 20–41 and 100 healthy pregnant aged between 17–41 were involved to study. Patients that have thyroid disease and low free T4 levels at first trimester were ruled out. Thyroid function tests of patients and healthy controls were assessed at first, second ...

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...

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: Type 1 diabetes mellitus (DM) is frequently associated with other autoimmune diseases. In this study, we aimed to evaluate thyroid autoantibodies, celiac antibodies and antiparietal antibody in patients with type 1 DM.Methods: Thyroid antithyroid peroxidase (anti-TPO) and antithyroglobulin (anti-Tg) antibodies, antiinsulin, antiislet cell and anti-glutamic acid decarboxylase (anti-GAD) antibodies, antiparietal antibody, antiendomisium, anti...

Introduction: Diagnosis of autoimmune thyroiditis is made by determination of elevated antibodies against thyroid peroxidase and thyroglobulin, and a hypoechoic pattern in ultrasound. In the present study we have performed a grey-scale quantitative analysis of thyroid echogenicity in the patients affected by autoimmune thyroiditis, obtaining the degree of hypoechogenicity associated with the appearance of thyroid dysfunction.Material and methods: Six hun...

Introduction: The incidence rate of papillary thyroid microcarsinoma (PTMC) has almost doubled during the recent years but treatment and follow up is still a matter of debate. In this study we aimed to analyze clinical and histopathological risk factors at the time of diagnosis and to observe their implications for treatment, follow up and prognosis.Patients and methods: Two hundred forty-eight PTMC patients were included in this study. The age, sex, the...
