Repetetive training of diabetic patient for medical nutrition and insulin therapy can improve the metabolic control

Altuntas Yuksel , Abi Aysel , Ozturk Feyza Yener

Introduction: A successfull diabetes management is not only restricted to medical therapy but also includes a difficult and new life style adoptation. Errors frequently observed in patients such as not complying with their diet program, wrong way of doing insulin injections and insufficient insulin doses, hinder the adequate metabolic control of the disease. Also, physco-social status and different education levels complicate the effectiveness of the first training of the pati...

The relation between metabolic syndrome and cognitive decline in elderly Turkish people

Zuhur Sayid Shafi , Karadag Berrin , Altuntas Yuksel

Objective: To determine the relationship between metabolic syndrome (MS) and cognitive decline in people over 60 years age.Methods: The age of the participants were between 60 and 89 years old (71.71±6.58). According to NCEP ATP III criteria 93 had MS and 47 had not. Cognitive performance was determined with the use of standardized mini mental test and the mini mental scores (MMS) of the two groups were compared. Apart from the MS we investigated th...

A novel case of pituitary metastasis presented as the syndrome of inappropriate antidiuretic hormone: an unexpected association

Zuhur Sayid Shafi , Kuzu Idris , Erol Rumeysa Selvinaz , Altuntas Yuksel

Introduction: Although the syndrome of inappropriate antidiuretic hormone (SIADH) has connection with various malignant tumors, the pituitary metastasis of malignant tumors are generally associated with diabetes insipidus.Case report: A 59 years old male patient presented to emergency service with frequent syncope attacks, nausea, loss of appetite and fatigue that began 2 weeks prior to admission. Marked obtundation was found on physical examination. The...

The relationship between low maternal serum 25-hydroxyvitamin D level and gestational diabetes mellitus according to the severity of 25-hydroxyvitamin D deficiency

Zuhur Sayid Shafi , Erol Rumeysa Selvinaz , Kuzu Idris , Altuntas Yuksel

Introduction: The results of publications investigating the relationship between low maternal serum 25-hydroxyvitamin D (25OHD) level and gestational diabetes mellitus (GDM) are controversial and none of these publications have investigated this relationship according to the severity of 25OHD deficiency. Therefore, this study was conducted to assess the relationship between low maternal serum 25OHD and GDM according to the severity of 25OHD deficiency.Me...

Lithium-associated hyperparathyroidism: a case report

Altuntas Yuksel , Ozturk Feyza Yener , Yildiz M. Serdar

Introduction: Lithium carbonate therapy has continued to be a mainstay treatment for bipolar disease and schizoaffective disorders. Hypercalcemia and hyperparathyroidism (HPT) is an underappreciated, but relatively common occurence, with a prevalence ranging from 6.3 to 50% in patients requiring long-term lithium therapy. It is stil unclear whether lithium initiates HPT or promotes an underlying subclinical state. Lithium antagonizes the calcium-sensing receptor (CASR) resulti...

Smoking shortens insulin-free interval in type 2 diabetics

Yesim Tijen , Durupinar Unsal , Ucak Sema , Saler Tayyibe , Altuntas Yuksel

Smoking is a modifyable risk factor in the incidence of impaired glucose tolerance and type 2 diabetes, but the data concerning the effect of smoking on the course of type 2 diabetes is limited. In this study, we aimed to investigate a possible relationship between smoking and the need of insulin therapy in patients with type 2 diabetes. 470 patients with type 2 diabetes were assessed for smoking habitus, marital and educational status, duration of diabetes, duration of insuli...

The role of endoscopic ultrasonography for localization of sporadic and men-1 syndrome associated insulinomas: Case series

Bilen Ogun , Altuntas Yuksel , Aggul Hunkar , Zuhur Sayid

IntroductionThe diagnosis of insulinomas is made biochemically. However, proper localization of insulinomas is essential before surgery. Non-invasive methods including magnetic resonance imaging (MRI), computed tomography, ultrasonography, glucagon-like peptide-1 receptor PET/CT, 68Ga-DOTATATE PET/CT, and invasive methods such as endoscopic ultrasonography (EUS) and selective arterial calcium stimulation test are used for preoperative localization. Howev...

Is biochemical assessment of pheochromocytoma necessary in adrenal incidentalomas with magnetic resonance features non-suggestive of pheochromocytoma?

Kuzu Idris , Zuhur Sayid Shafi , Ozel Alper , Ozturk Feyza Yener , Altuntas Yuksel

Objective: It is not currently well known whether pheochromocytomas can be ruled out based on low intensity on T2-weighted sequences and signal loss on out-off phase magnetic resonance imaging (MRI) sequences. Hence, in this study we aimed to investigate whether biochemical screening for pheochromocytoma in patients with adrenal incidentalomas (AI) showing MRI features not suggesting pheochromocytoma would prove beneficial.Methods: We performed MRI for 3...

A rare cause of increased bone mineral density in adulthood: autosomal dominant osteopetrosis

Altuntas Yuksel , Ozturk Feyza Yener , Kuzu Idris , Canat M Masum , Karatas Savas , Cakir Sezin Dogan

Introduction and aim: Osteopetrosis is a rare genetic disorder of reduced osteoclastic bone resorption. Defective bone remodelling induces skeletal sclerosis and abnormally dense but brittle bones. We present here a case of autosomal dominant osteopetrosis type II as a cause of high bone mineral density (BMD).Case report: A 52-years-old woman with a complaint of bone pain and headache referred to our clinic for evaluation of high BMD. Her medical history...
