Ali Tam Abbas , Faki Sevgul , Ozdemir Didem , Aydin Cevdet , Ersoy Reyhan , Cakir Bekir

Introduction: Hysterosalphingography (HSG) is the radiographic examination of uterine cavity and fallopian tubes. It is generally used during evaluation of infertility and radioopaque contrast is injected through cervical duct during the procedure. Lipiodol which is the most commonly used contrast media in HSG is a fatsoluble iodinated contrast media. This iodine is progressively cleared from the body in a period ranging from a few weeks to a few months. Here, we present a 6 w...

Fluctuating thyroid hormones in Graves disease: a case series of brittle Graves

Cuneyt Bilginer Muhammet , Faki Sevgul , Aydin Cevdet , Ozdemir Didem , Ali Tam Abbas , Ersoy Reyhan , Cakir Bekir

Introduction: Brittle hypertyroidism is a term used for the clinical situation characterized by hypo-hyperthyroidism with antithyroid drugs, despite good compliance and follow-up. Here, we presented five patients suggested to have Brittle Graves.Case-1: Thyrotoxicosis was observed in a 57-year-old female patient and Graves was diagnosed after laboratory and imaging examinations 25 months after initiation of propylthiouracil 50 mg/day, she developed hypot...

Differentiated thyroid cancer in patients taking lithium for bipolar affective disorder: a case series

Ali Tam Abbas , Aydin Cevdet , Ozdemir Didem , Bilginer Muhammed Cuneyt , Ersoy Reyhan , Cakir Bekir

Aim: Lithium bicarbonate is a drug used in the initial treatment of bipolar disorders. Lithium is an element of alcali metal group and besides being a causative agent for goiter and hypothyroidism primarily, it has also some antithyroid effects. Rarely, lithium may cause hyperthyroidism secondary to thyroiditis or probably autoimmune mechanisms. The association between lithium and thyroid cancer is very little known subject. In this case series, we presented differentiated thy...

Coincidental prolactinoma and parathyroid adenoma in a patient with negative MEN1 and MEN4

Faki Sevgul , Aydin Cevdet , Cuneyt Bilginer Muhammet , Yukselguler Bagdegul , Abbas Tam Ali , Kilic Mehmet , Cakir Bekir

Introduction: Multiple endocrine neoplasia type 1 (MEN 1) is associated with neoplasia and hyperfunction of the parathyroid and pituitary glands, pancreatic islet cells, and neuroendocrine cells of the gut. Many authors advocate routine subtotal or total parathyroidectomy and autotransplantation for these patients. Here we demostrate negative MEN1 and MEN4 gene mutation analysis in a case with prolactinoma and a large parathyroid adenoma that could not be localized with preope...

A patient with acromegalic heart disease

Houssein Mehdi , Turan Kubra , Temizhan Ahmet , Tural Balsak Belma , Ali Tam Abbas , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

A 36 years of old patient was admitted to the intensive care unit of cardiology when he experienced palpitations and orthopnea. The patient’s complaints started about 2 years ago as syncope and sudden shortness of breath. Thorax CT showed pleural effusion and increased cardiothoracic index. Findings on ECHO were : Ejection fraction 35%, severe mitral regurgitation and global hypokinesia. Coronary angiogram showed a fibrocalcific plaque noted in in the distal LAD. The pati...

Association of ABO blood groups with diabetic microvascular complications

Faki Sevgul , Ince Nurcan , Ali Tam Abbas , Turan Erdogan Beril , Cuhacı Seyrek Neslihan , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

Background: Micro vascular complications are the major outcome of Type 2 Diabetes Mellitus progression, which reduces the quality of life and increases diabetic morbidity & mortality. As the incidence of type 2 diabetes is growing day by day; our search for its aetiology and pathogenesis is also ever growing to predict its risk factors and early screening for better care and prevention of its complications. Many studies have tried to link susceptibility of type 2 diabetes ...

Higher thyrotropin can be used as an additional risk factor in prediction of malignancy in euthyroid thyroid nodules evaluated by cytology based on Bethesda system

Baser Husniye , Topaloglu Oya , Ali Tam Abbas , Evranos Berna , Alkan Afra , Sungu Nuran , Gurkan Dumlu Ersin , Ersoy Reyhan , Cakir Bekir

Introduction: Recently, it has been suggested that thyrotropin (TSH) concentration can be used as a marker for prediction of thyroid malignancy. However, the association between the cytology results and TSH levels is not clear. In this study, we aimed to investigate the relationship between TSH levels and Bethesda categories and determine the role of TSH levels in prediction of malignancy in patients with different Bethesda categories.Methods: The data o...

Malignancy risk and false negative rate of fine needle aspiration cytology in thyroid nodules equal or greater than 4 cm

Bestepe Nagihan , Ozdemir Didem , Ali Tam Abbas , Dellal Fatma Dilek , Kilicarslan Aydan , Parlak Omer , Ersoy Reyhan , Cakir Bekir

Background: We aimed to evaluate malignancy rate in thyroid nodules ≥4 cm and determine false negativity of fine needle aspiration biopsy (FNAB) in these nodules.Methods: Patients who underwent thyroidectomy between January 2007 and December 2014 in our institution were reviewed. Demographical and clinical data and preoperative ultrasonography (US) findings were obtained from the medical records. The nodules in these patients were grouped as &#8805...

Can ratio of primary tumor diameter to total tumor diameter be a new parameter in the differential diagnosis of agressive and favorable multifocal papillary thyroid microcarcinoma?

Ali Tam Abbas , Ozdemir Didem , Cuhaci Neslihan , Baser Husniye , Dirikoc Ahmet , Aydin Cevdet , Kilicyazgan Aylin , Ersoy Reyhan , Cakir Bekir

Introduction: In this study, we aimed to evaluate the usefulness of ratio of primary tumor diameter to total tumor diameter as a new parameter for the differentiation of agressive and favorable papillary thyroid microcarcinomas (PTMC).Methods: The diameter of the largest tumor focus was taken as the primary tumour diameter (PTD). For multifocal tumors, total tumor diameter (TTD) was calculated as the sum of the maximal diameter of each lesion. A ratio wa...

Nivolumab induced relapse of graves’ disease: A case report

Evranos Ogmen Berna , Ali Tam Abbas , Aydin Cevdet , Dirikoç Ahmet , Baser Husniye , Ersoy Reyhan , Cakir Bekir

Background: Immune checkpoint inhibitors, including anti-programmed cell death-1 (PD-1) antibodies, have become promising treatments for a variety of advanced malignancies. Nivolumab, an anti–PD-1 monoclonal Ab, is an effective treatment of unresectable metastatic melanoma, non–small cell lung cancer, renal cell carcinoma, head and neck cancer, Hodgkin lymphoma, and gastric cancer. These medicines can cause immune-related adverse events (irAEs), including endocrino...
