A latent autoimmune diabetes in adults (LADA) case renamed after six years of diabetes diagnosis when complicated with diabetic ketoacidosis induced by dapagliflozin

Ekiz-Bilir Betul , Bilir Bulent , Elbuken Gulsah

Introduction: LADA (Latent autoimmune diabetes in adults) is an adult-onset and more indolent variety of autoimmune type 1 diabetes mellitus. In autoimmune diabetes, younger individuals typically have a rapid rate of beta-cell destruction and usually present with ketoacidosis, while adults often maintain sufficient insulin secretion to prevent ketoacidosis for many years. LADA is usually misdiagnosed initially as type 2 diabetes due to its late onset but LADA patients are anti...

The relationship between serum uric acid and insulin resistance and sensitivity parameters in Turkish type 2 diabetes mellitus patients

Ekiz-Bilir Betul , Bilir Bulent , Soysal-Atile Neslihan , Elbuken Gulsah

Summary: Hyperuricemia is associated with glucose metabolism disorders clinically. In this study, we evaluated the relationship between serum uric acid concentrations and some insulin resistance/sensitivity parameters in Turkish type 2 diabetes mellitus patients.Methods: The anthropometric and laboratory data of 87 type 2 diabetes patients of both sexes (35 male, 52 female) were evaluated retrospectively. HOMA-IR (homeostatic model of insulin resistance)...

Response to treatment with temozolomide in cases with invasive pituitary macroadenomas: A single-center experience

Bilen Ogun , Aggul Hunkar , Elbuken Gulsah , Zuhur Sayid

IntroductıonRecent studies suggest temozolomide as an effective treatment modality in invasive pituitary adenomas that did not respond to conventional treatments. In this case series, we present three cases of invasive pituitary adenomas that did not respond to conventional medical treatments and radiotherapy and were subsequently treated with temozolomide.CasesThe first patient had an invasive prolactin...

A novel heterozygous mutation in exon 3 of VHL gene leading to Von Hippel-Lindau disease in a Turkish family

Yildirim Ozge Tasgin , Yildiz Ismail , Horozoglu Fatih , Gonen Aysun , Yazici Cenk Murat , Elbuken Gulsah , Zuhur Sayid

Background: Von Hippel-Lindau disease (VHL) is an autosomal dominant disease, characterized by haemangioblastomas of the retina and CNS, renal cell carcinomas (RCC) and renal cysts, pheochromocytomas, pancreatic neuroendocrine tumors and cysts, and endolymphatic sac tumors. VHL is associated with a germline mutation of the VHL tumor suppressor gene on the short arm of chromosome 3. The type-1 disease is caused by mutations, leading to severe disruption of protein acti...

The frequency of Cushing’s disease, ACTH independent Cushing’s syndrome, and autonomous cortisol secretion among turkish patients with obesity

Atar Resit Volkan , Yildiz Ismail , Topcu Birol , Elbuken Gulsah , Zuhur Sayid

Objectives: The frequency of Cushing’s disease (CD), ACTH independent Cushing’s syndrome (CS) and autonomous cortisol secretion (ACS) in patients with obesity is not well known and the results of the studies are heterogeneous. Therefore, in the present study, we aimed to assess the frequency of CD, CS, and ACS among patients with obesity.Methods: In this study, 813 consecutive patients [683 female, mean age 46.47±14.23-year-old, mean BMI 3...

Clinical evaluation of TSH-receptor antibody measured by a third generation fully automated electrochemiluminescence immunoassay method in Turkish patients with Graves’ disease

Yildirim Ozge Tasgin , Elbuken Gulsah , Topcu Birol , Yildiz Ismail , Zuhur Sayid

Objective: Despite the high sensitivity of TRAb measured by modern assay methods, some patients with Graves’ disease (GD) may still have normal TRAb levels. Therefore, the purpose of this study was to determine the clinical utility of TRAb measured by a third generation assay method, and to determine it’s relationship with clinical and laboratory parameters in Turkish patients with GD.Methods: In this study, 328 consecutive treatment-naive pati...

Eucalcemic parathyroid hormone elevation after parathyroid surgery for sporadic primary hyperparathyroidism

Elbuken Gulsah , Ozkan-Gurdal Sibel , Balkan Makbule Begum , Zuhur Sayid Shafi

Introduction: Serum parathormone (PTH) levels may remain elevated in some patients after surgery despite achievement of normal serum Ca levels. The factors contributing to this phenomenon have not been fully elucidated yet. In this study, we retrospectively analysed the data of patients whose serum Ca levels returned to normal after parathyroid surgery in our center.Patients and methods: Computer records of 35 patients who had undergone parathyroid surge...

A hypopituitarism case diagnosed after sphenoid sinus mucocele operation

Ekiz-Bilir Betul , Bilir Bulent , Oz Aysel , Gunes-Ciftci Halide , Soysal-Atile Neslihan , Elbuken Gulsah

Introduction: Mucoceles-mucus containing benign cysts of paranasal sinuses- are common with an incidence of 1% but involvement of sphenoid sinus is much less common. In this case report, we reported a patient presented with hypopituitarism after sphenoid mucocele drainage operation.Case report: A 59- year-old woman was admitted to our endocrinology out-patient clinics with a complaint of fatigue over the past 2 months. One month prior to admission, she h...

Primary hyperparathyroidism detected in a patient undergoing two prior thyroidectomies for follicular thyroid carcinoma: a case report

Elbuken Gulsah , Gulciftci-Dagci Zehra , Ozcaglayan Omer , Tonbul Ayse Tuba , Atile Neslihan Soysal , Zuhur Sayid

Introduction: Primary hyperparathyroidism (PHPT) is usually characterized by overproduction of parathormone (PTH) due to a solitary parathyroid adenoma. Its treatment involves surgical removal of the solitary adenoma or hyperplastic parathyroid glands that secrete PTH. Medical treatment options are used for patients with conditions that preclude surgical operation.Case presentation: A 57-year-old female patient underwent left total and right subtotal thy...

Does cigarette smoking affect serum total cortisol and salivary cortisol levels?

Elbuken Gulsah , Karaca Zuleyha , Tanriverdi Fatih , Unluhizarci Kursad , Simsek Yasin , Kelestimur Fahrettin

Aim: Although there are some studies regarding the effects of cigarette smoking on serum total cortisol (STC) and salivary cortisol (SaC) levels, the results are still challenging. For this purpose, we aimed to determine the effects of cigarette smoking on STC and/ or SaC levels in a small group of healthy volunteers.Study design: 15 (five female and ten male) cigarette smoker with the mean age of 39.47±14.27, and 15 age and gender matched non-smoke...
