Turan Erdogan Beril , Keskin Caglar , Burcak Polat Şefika , Nasiroglu Imga Narin , Ozdemir Didem , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

Background: Hypoparathyroidism (HypoPT) is a rare condition that is characterized by hypocalcemia and hyperphosphatemia due to low or inappropriately normal serum levels of parathyroid hormone (PTH) for at least 6 months. The long-term complications of hypoparathyroidism indicate the necessity of screening them. In the follow-up of these patients according to hypoparathyroidism guidelines is recommended; calcium, phosphorus, albumin, magnesium, creatinine, and eGFR levels shou...

Introduction: Insulinoma is a rare neuroendocrine tumor that is difficult to diagnose due to its obscure location. Conventional radiographic methods have low sensitivity and are inadequate to detect insulinoma. Selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma that could not be located by radiographic methods and evaluated them with SACST.Case 1: A 48-...

The Effect of Ramadan fasting on thyroid hormone levels in patients on levothyroxine treatment

Dellal Fatma Dilek , Ogmen Berna , Ozdemir Didem , Cuhaci Fatma Neslihan , Polat Sefika Burcak , Ersoy Reyhan , Cakir Bekir

Aim: Contradictory results in limited number of studies were reported about the effects of Ramadan fasting on thyroid hormones. We aimed to evaluate the thyroid functions in Ramadan, and compare late evening or pre-sahour use of levothyroxine in patients being treated for hypothyroidism.Methods: Patients taking levothyroxine for hypothyroidism who were seen in the last one week before Ramadan (8–15 May 2018) and had normal thyroid functions were rec...

Upper gastrointestinal symptoms, endoscopic and pathological features, and serum gastrin and chromogranin A levels in patients with primary hyperparathyroidism

Ersoy Osman , Evranos Ogmen Berna , Burcak Polat Sefika , Ozturk Levent , Gumuskaya Ocal Berrak , Cakir Bekir , Ersoy Reyhan

Introduction: Upper gastrointestinal (UGI) symptoms are frequently encountered in patients with primary hyperparathyroidism (PHPT). Some of these symptoms may improve after PHPT treatment, while hypercalcemic state may also cause permanent effects. We aimed to evaluate UGI symptoms, UGI endoscopic and pathologic features and determine the relationship between these features with serum chromogranin A (CgA) and gastrin in PHPT patients.Methods: Seventy-one...

Boysan S Nur , Altunrende Burcu , Dalar Levent , Acik M Eren , Canpolat I Polat , Akdeniz C Selcan , Gonen M Sait

Parathormon treatment for osteoporosis is rarely complicated with hypercalcemia. Vitamin D treatment with high doses frequently can cause asymptomatic intoxication.We present a case with life-threatening hypercalcemia complicated both parathormon and high-dose vitamin D.A 85-year old woman hospitalized for sudden-onset confusion. In history she had coronary-artery by-pass operation and a serebrovascular accedant. She was treated with teriparatide 20 &#95...

Evaluation of oxidative stres by means of thiol-disulphide homeostasis in patients with euthyroid Hashimoto’s thyroiditis

Dirikoc Merve , Topaloglu Oya , Aydin Cevdet , Dirikoc Ahmet , Polat Sefika Burcak , Erel Ozcan , Ersoy Reyhan , Cakir Bekir

Aim: In this study we aimed to evaluate the oxidative stress via evaluating changes in dynamic thiol-disulphide status in euthyroid patients with Hashimoto’s thyroiditis (HT).Methods: Fifty euthyroid patients with HT and 50 healthy individuals were enrolled in this study. Thyroid function tests (free triiodothyronine (fT3), free thyroxine (fT4), thyrotropin (TSH)), acute phase reactants (C-reactive protein (CRP), high sensitive CRP (hs-CRP)) and thi...

A cancer of undetermined significance – incidental thyroid carcinoma

Evranos Berna , Burcak Polat Sefika , Neslihan Cuhaci Fatma , Baser Husniye , Topaloglu Oya , Kilic Mehmet , Kilicarslan Aydan , Ersoy Reyhan , Cakir Bekir

Introduction: Incidental thyroid carcinoma (ITC) in patients operated on for a benign disease is frequent. ITC characteristics in patients operated for malign disease, but not sampled by fine needle aspiration (FNA) or seen in ultrasonography, is unknown. We aimed to compare ITC with nonincidental ITC (NITC) in this study.Material and method: Retrospective analyses of 918 individual patients who were operated for benign and malign thyroid disease in our ...

Bethesda classification is highly predictive especially for the diagnoses of aggressive variants of papillary thyroid carcinoma

Evranos Berna , Polat Sefika Burcak , Baser Husniye , Ozdemir Didem , Kilicarslan Aydan , Yalcin Abdussamed , Ersoy Reyhan , Cakir Bekir

Background: Fine needle aspiration biopsy (FNAB) has proven to be the most valuable diagnostic procedure for preoperative discrimination of benign and malignant nodules. Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized reporting and cytomorphological criteria in aspiration smears. In this study, we aimed to determine malignancy rates in nodules with different cytology results and diagnostic value of TBSRTC for variants of papillary thyroid carcinom...

The relationships of bisphenol A levels with leptin and adiponectin in premenopausal women

Polat Sevgi , Yurekli Banu Sarer , Kocabas Gokcen Unal , Durusoy Raika , Aksit Murat , Bozkaya Giray , Yuksel Arif , Saygili Fusun

Aim: Bisphenol A (BPA) is the most common endocrine disruptor among environmental estrogens. BPA is an ingredient that is commonly used in polycarbonate plastics. In this study, our main concern is to measure the levels of BPA in premenopausal obese women and to examine the relationship of BPA with adiponectin and leptin.Materials and methods: 47 obese women and 39 non-obese healthy women were enrolled in this study. All participants were premenopausal. ...

The diagnostic value of parathyroid hormone washout in primary hyperparathyroidism patients with negative or unequivocal 99mTc-MIBI results

Aydin Cevdet , Polat Sefika Burcak , Dellal Fatma Dilek , Kaya Cafer , Turkolmez Seyda , Kilic Mehmet , Ersoy Reyhan , Cakir Bekir

Introduction: Primary hyperparathyroidism (pHPT) is a common endocrine disease mainly caused by single or multiple hyperfunctioning parathyroid lesions. In 2–7% of cases, surgery is not curative at first operation and reoperation is required. Ultrasonography and sestamibi scan are the most widely used methods for identification of the culprit parathyroid gland with the disadvantage of high false positives caused by other cervical pathologies. Herein we aimed to search the...
