Severe insulin resistance with cirrhosis: A case report

Durmaz Himmet , Evranos Ogmen Berna , Ahmadova Konul , Kucukcongar Yavas Aynur , Keskin Caglar , Dirikoc Ahmet , Cakir Bekir

Background: Alstrom syndrome is a rare autosomal recessive genetic disorder characterised by vision loss, hearing loss, childhood obesity, insulin resistance and hyperinsulinemia, type 2 diabetes, hypertriglyceridemia, cardiomyopathy, and progressive pulmonary, hepatic, and renal dysfunction. Hyperinsulinemia develops early, and pancreatic islets show beta-cell proliferation, thus suggesting that both insulin resistance and increased insulin secretion might contribute to gluco...

A case of graves disease with hepatic dysfunction, thrombocytopenia and paralysis

Houssein Mehdi , Turan Kubra , Evranos Ogmen Berna , Aydin Cevdet , Ozdemir Didem , Faki Sevgul

Background: Graves’ disease is an autoimmune disease that is characterized by production of excess thyroid hormones by thyroid gland, which is called hyperthyroidism. Generally, clinical presentations of Graves’ disease range from asymptomatic disease to overt symptomatic hyperthyroidism with heat intolerance, tremor, palpitation, weight loss, and increased appetite. Single-cell lineage haematological abnormalities, such as anemia, leukopenia, and thrombocytopenia,...

A case of diabetes insiputus due to ectopically located neurohypophysis presented during pregnancy

Bilginer Muhammet Cuneyt , Polat Burcak , Ogmen Berna , Topaloglu Oya , Baser Husniye , Ersoy Reyhan , Cakir Bekir

Background: Gestational diabetes insipidus (DI) is a rare complication of pregnancy, usually developing in the last trimester and resolves spontaneously 4–6 weeks post-partum. It is mainly caused by excessive vasopressinase activity, an enzyme expressed by placental trophoblasts which metabolises arginine vasopressin (AVP). However in some cases, it can develop in a patient who had limited reserve of ADH and marginal central DI prior to pregnancy and may not reso...

Thyroid amyloidosis mimicking medullary thyroid carcinoma

Faki Sevgul , Aydin Cevdet , Ogmen Berna , Dirikoc Ahmet , Mehmet Inan Haci , Cakir Bekir

Introduction: Amyloid accumulation in the thyroid gland leading to a clinically detectable mass is a rare clinical entity. The diagnosis of thyroid amyloidosis can be confused clinically as well as cytologically with both colloidal goiter or neoplastic processes of the thyroid. We report a case of thyroid amyloidosis that was initially misinterpreted as medullary thyroid carcinoma (MTC) clinical and cytological examination.Case: A 24 years old man with c...

Two cases of Graves dermopathy: A rare and pathognomonic symptom

Bilginer Muhammet Cuneyt , Polat Burcak , Ogmen Berna , Ersoy Reyhan , Cakir Bekir

Introduction: Pretibial myxedema is a rare manifestation of Graves’ disease caused by local autoimmune attack of the connective tissue probably mediated by anti TSH receptor autoantibodies (TRab). Its prevalence changes between 0.4 and 5% in Graves ‘patients and usually is accompanied by opthalmopathy. The diagnosis requires physical examination and clinical suspicion and in doubtful cases biopsy may be performed.Case 1: Sixty four years old fe...

Comparison of patients with normocalcemic and hypercalcemic primary hyperparathyroidism

leyla akdoğan , Burcak Polat Sefika , Aydin Cevdet , Ogmen Berna , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

ObjectivePrimary hyperparathyroidism (PHPT) is the most common cause of hypercalcemia. A group of patients who were followed up with a diagnosis of PHPT had normal calcium levels with high parathyroid hormone (PTH) levels. For the diagnosis of normocalcemic PHPT, secondary causes of hyperparathyroidism such as vitamin D deficiency should be excluded. In this study, the data of 318 PHPT patients who were operated were retrospectively analyzed, and biochem...

Awareness of normal weight, overweight and obese patients about complications, risk factors and prevention of obesity

Dirikoc Ahmet , Genc Birgul , Ozdemir Didem , Evranos Ogmen Berna , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

BackgroundWe aimed to determine the awareness of obese, overweight and normal weight patients about the complications, causes and prevention of obesity.MethodsPatients who admitted to our clinic during a four months period were included. Demographical features, familial histories of obesity, smoking, alcohol use, chronic diseases, medications, medical nutrition therapy and exercise habits were determined. Ans...

Calcitonin washout in the diagnosis of medullary thyroid cancer

Evranos Ogmen Berna , Ince Nurcan , Akdogan Leyla , Aksoy Altınboga Aysegul , Aydin Cevdet , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

Background: Medullary thyroid cancers (MTC) originate from parafollicular C cells and constitute 3-5% of all thyroid cancers. Calcitonin (CT) measurement is useful in the diagnosis of MTC. The sensitivity and specificity of CT are low in the measurement alone, and the sensitivity and specificity increase when used with pentagastrin and calcium stimulation tests. However, the difficulty of accessing pentagastrin, the uncertainty of the cut-off value in calcium stimulation tests...

Adrenal incidentaloma, single center clinical experience

Turan Erdogan Beril , Evranos Ogmen Berna , Keskin Caglar , FAKI Sevgul , Aydin Cevdet , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

Backgorund: Adrenal incidentalomas (AI) are lesions discovered incidentally on imaging without clinical symptoms or examination findings. AI can produce hormones in 5-30% of cases. Autonomic cortisol secretion (ACS) is the most common of these. Although ACS is asymptomatic, it increases the risk of metabolic disorders.Methods: Patients aged<18 years with adrenal adenoma and upper abdominal MRI who presented and were examined in the endocrinology outp...

Selective Arterial Calcium Stimulation Test In Two Cases With Occult Insulinoma

Baykal Gokhan , Evranos Ogmen Berna , Ozdemir Mustafa , Bostancı Birol , Burcak Polat Şefika , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

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-...
