Asoglu Veysi , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Ustun Funda , Guldiken Sibel

Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome and is the second most common cause of tumor-related hypoglycemia following insulinoma. Its prevalence is not known and is likely that many cases would go undiagnosed. In here, we describe a patient with PNET who presented with severe hypoglycemia.A 37-year-old male with known metastatic Pancreatic neuroendocrine tumors (PNET) presented with weight loss, sweating, and tremor, epi...

Ugur Kader , Artas Hakan , Balin Mehmet , Aykut Esra , Demircan Selcuk , Orhan Bedrettin , Gozel Nevzat

Introduction: Vitamin D is a fat soluble prohormone and can be produced in the body with adequate sunlight exposure or taken up by consumed foods or supplements. Recently vitamin D deficiency has been seen in pandemic. A rare disease, vitamin D intoxication is usually iatrogenic. High levels of 25(OH) vitamin D increases the intestinal calcium absorption and causes severe and refractory hypercalcemia. In this case report we presented a patient with pancreatitis and hypercalcem...

Karaca Anara , Gulcelik Nese Ersoz , Bakar Filiz , Akgul Giray , Sahiner Zeynep , Gulcelik Mehmet Ali

Objective: The finding of new biomarkers is needed to have an early diagnosis of breast cancer. In this study we evaluated serum levels of carboxylated osteocalcin (OC) and uncarboxylated osteocalcin(UcOC), CRP as a diagnostic biomarker for breast cancer.Design and methods: Blood samples of 39 women with newly diagnosed breast cancer with stage I were obtained before surgery and 39 age and BMI matched health women were selected as controls.<p class="...

Serum sclerostin and dickkopf-1 levels in polycystic ovary syndrome patients

Bilem Ogun , Bilem Yildiz , Eroglu Mustafa , Turkon Hakan , Akdeniz Yasemin Sefika , Asik Mehmet

Introduction: Polycystic ovary syndrome (PCOS) is the most common endocrine pathology in premenopausal women and it is a complex syndrome affecting various systems. Numerous studies have been made about how the PCOS effects on bone metabolism, but currently there is no clear information. Wnt pathway plays important role in the regulation of bone metabolism. The sclerostin(Scl) and Dickkopf-1 (DKK1) inhibit this pathway and they has recently become a therapeutic target of osteo...

Effects of combination of metformin and pioglitazone on AMPK/mTOR signal pathway, p53 and apoptosis in human anaplastic thyroid cancer cells

Kutbay Nilufer Ozdemir , Erdogan Mehmet , Yurekli Banu Sarer , Kurt Cansu Caliskan , Gunduz Cumhur , Avci Cigir Biray

Thyroid cancer is the most common malignant tumor of the human endocrine system. Recently, its incidence has increased significantly. Anaplastic cancer constitutes 2–4% of thyroid cancers and remains aggressive. The life expectancy is 2–6 months. It is often beyond the surgical margin. External radiation therapy or chemotherapy are the treatment options. Therefore, new therapeutic approaches are needed. Peroxisome proliferator-activated receptor (PPAR) gamma is a DNA...

Insulin resistance and BRAFV600E mutation in the patients with differentiated thyroid carcinoma

Celik Mehmet , Yilmaz Bulbul Buket , Ayturk Semra , Tastekin Ebru , Can Nuray , Sezer Atakan , Ustun Funda

Aim: The incidence of nodular thyroid disease is high among patients with insulin resistance. The aim of this study is to evaluate the relationship between BRAFV600E mutation and insulin resistance in the patients with papillary thyroid cancer.Materials and methods: We examined clinical and laboratory data of 103 patients who had been followed up by our department between the years 2010 and 2015. The diagnosis of insulin resistance (IR) was made when the...

A rare cause of respiratory failure: Anaplastic carcinoma

Celik Ece , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Can Nuray , Serez Bilkay , Guldiken Sibel

Anaplastic thyroid carcinoma (ATC) is one of the most aggressive and lethal human malignancies. The median survival time following diagnosis is typically six months or less. Rapidly growing tumors may cause respiratory failure by compressing trachea. A 71-year-old woman presented with 1-month history of dyspnea, cyanosis and rapidly enlarging neck mass for the past 2 weeks. She had been suffering from multinodular goiter disease. Physical examination revealed a large, fixed an...

Our experience of strain elastography in the evaluation of thyroid nodules

Fenkci Semin Melahat , Coşkun Mehmet , Topsakal Senay , Yaylalı Guzin Fidan

Introduction: Thyroid nodule is a common finding in neck ultrasonography performed in adult age group. Appropriate management of patients with thyroid nodules accuretly is very difficult process. Fine needle aspiration biopsy (FNAB), is the traditional invasive method used to identify nodules. Investigations are continuing for noninvasive techniques. Elastography is the imaging new technic,to evaluate the nodules. Aim of this study to evaluate the results of FNAB and elastogra...

Evaluation of preoperative ultrasonographic and biochemical features of patients with aggressive parathyroid disease: Is there any reliable predictive marker?

Cakir Bekir , Burcak Polat Sefika , Kilic Mehmet , Ozdemir Didem , Aydin Cevdet , Sungu Nuran , Ersoy Reyhan

Introduction: Parathyroid cancer (PC) is rare accounting for <1% of all presentations. Tumors that demonstrate these atypical features and do not fulfill criteria for carcinoma can be classified as atypical adenomas (APA). Herein we aimed to evaluate the clinical and biochemical features of the patients with an atypical parathyroid adenoma or carcinoma and compare it with benign parathyroid adenomas.Method: Twenty-eight patients who were operated for...

Does IGF2BP2 gene polymorphism have an effect on the development of gestational diabetes mellitus?

Ilke Cikman Duygu , Seyhan Cikman Muzaffer , Ali Kasifoglu Mehmet , Dagdelen Selcuk

Objective: Gestational diabetes mellitus (GDM) is a multifactorial disorder with environmental factors and genetic modifiers. IGF2BP2 gene polymorphisms are shown to be involved in T2DM and diabetic nephropathy. Here, we aimed to document the association between IGF2BP2 gene polymorphism and GDM to understand the pathogenesis of GDM.Design: Matched, case-control study.Method: Ninety-three patients with GDM and 89 healthy pregnant s...
