Abstract
Objective Both obesity and periodontal diseases are significant diseases that affect the quality of life. Recent studies have focused on the relationship between obesity and periodontal disease. The aim of this study is to determine the pathophysiological relationship between obesity and periodontal disease by evaluating the clinical periodontal parameters and oxidative status. Subjects and Methods The study included 80 individuals divided into four groups including 20 individuals in each group as following; periodontally healthy patients with normal weight, (NH), patients with chronic periodontitis and normal weight (NCP), periodontally healthy patients with obesity (OH) and patients with chronic periodontitis and obesity (OCP). Clinical periodontal parameters were recorded, and serum, saliva and gingival crevicular fluid (GCF) samples were obtained. Local and systemic levels of total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) were assessed biochemically. Results No statistically significant difference was found among the groups regarding TAS, TOS and OSI values in serum and saliva samples (p>0.05). GCF-TAS values in NH group were statistically significantly higher compared with other groups (p<0,05) . GCF TOS values increased in obese groups (OH, OCP) compared with non-obese groups (NH, NCP) (p<0.05). Our results suggest that obesity and chronic periodontitis do not effect oxidant/antioxidant levels in serum and saliva. Conclusions Many factors such as daily living conditions of the individual, stress and nutritional habits TAS and TOS levels of the individual may affect oxidative stress parameters. However, these factors could not be standardized in the study.

Abstract
Introduction Since there is no objective criteria, unique clinical symptom or laboratory test to make the diagnosis of conversion disorder; its diagnosis and treatment is challenging which leads to a poor prognosis. Objectives The aim of this study is to investigate the brain metabolic activity of patients with conversion disorder with PET/MRI. Methods 12 conversion disorder patients were included. Somatosensory Amplification Scale, Somatoform Dissociation Scale, Patient Health Questionnaire-15, Toronto Alexithymia Scale were filled in by the participants. Neurological, mental status examinations, Wechsler Adult Intelligence Scale-Revised Form (WAIS-R) and brain F18-FDG-PET/MRI were performed. Structured Clinical Interview for DSM-5, Hamilton Depression and Anxiety Scales were administered. Results 83% of the patients were female, the mean age was 33 years and average education period was 10,2 years. WAIS-R total scores were consistent with low avarage intelligence level.Cerebral hypermetabolism was detected in the primary visual cortex. Average regional brain metabolic activity had a tendency to increase in bilateral prefrontal, right sensorimotor (SM),cingulate,right inferior parietal,occipital lateral,right temporal lateral cortices and cerebellum. Each region was metabolically correlated with the homologous contralateral regions. Significant correlations in the same direction was found between frontal and occipital lateral & primary visual cortices; cerebellum and left sensorimotor cortex; anterior cingulate cortex(ACC) and superior parietal cortex & cerebellum. No correlations were found between ACC and left SM cortex. Conclusions Findings of our study indicate that there are moderate changes in regional brain metabolic activities and inter-regional correlations in patients with conversion disorder. In order to confirm these findings, furter functional neuroimaging studies are needed. Disclosure No significant relationships.

Abstract
OBJECTIVE In this study, we aimed to evaluate the effect of tumor size and tumor sidedness on prognosis in patients with stage 2 colon cancer. PATIENTS AND METHODS Data of 501 patients diagnosed with stage 2 colon cancer were evaluated retrospectively. It was evaluated whether the patients' age, gender, tumor differentiation, tumor node metastasis (TNM) stage, overall survival rate, and disease-free survival rate had any correlation with horizontal tumor diameter and tumor sidedness. In the ROC analysis performed to determine the cut-off value for the tumor diameter, which we think will predict survival, no significant results were obtained with maximum sensitivity and specificity. Therefore, the median value of the tumor diameter, which is 5 cm, was accepted as the cut-off value. Kaplan-Meier method and Cox regression analysis were used for survival analysis and determination of prognostic factors. RESULTS When the patients were evaluated in terms of tumor localization, 189 (37.7%) patients had right colon tumors and 312 (62.3%) patients had left colon tumors. There was no statistically significant difference in terms of disease-free survival and overall survival according to tumor localization. When the patients were analyzed by dividing them into two groups according to the horizontal tumor size (<5 cm and ≥5 cm), no statistically significant difference was found between the groups in terms of disease-free survival (DFS) and overall survival (OS) p=0.085, p=0.699, respectively. CONCLUSIONS Our results suggest that the management of patients with stage 2 colon cancer requires a better understanding of tumor biology rather than features such as tumor size and localization.

Abstract
AIMS In August 2015, FDA published a black box declaring that DPP-4 inhibitors may cause severe joint pains. The impact on autoimmunity marker positivity of these drugs has not been comprehensively evaluated. We compared the incidence of arthritis/arthralgia in patients with T2DM who were using DPP-4 inhibitors and patients who were not using. METHODS A number of 93 DPP-4 inhibitor users and 107 non-users were included into the study. Arthritis/arthralgia were found in 41 of 93 (44.1%) DPP-4 inhibitor users and in 19 of 107 (17.8%) non-users (p<0.05). RESULTS No inflammatory rheumatological condition was identified in 27 of 41 (65.9%) patients in DPP-4 inhibitor user group as well as in 13 of 19 (68.4%) patients in non-user group (p>0.05). After adjusting for gender the incidence for arthritis/arthralgia was significantly increased in the DPP-4 inhibitor user group (p value for any DPP-inhibitor <0.05). There was 3.77 times increased risk for arthritis/arthralgia in the DPP-4 inhibitor using group (p value= 0.001) and this risk increases 2.43 times for each year of DPP-4 inhibitor usage. CONCLUSIONS Arthritis/arthralgia were more common among T2DM patients who were using DPP-4 inhibitors compared to non-users, but the seropositivity did not differ between DPP-4 inhibitor users and non-users.

Abstract
The aim of this research was to study the prevalence of chronic headache (CH) and associated socio-cultural factors in Turkish immigrants and native Germans. Five hundred and twenty-three Turkish and German company employees were screened using a standard questionnaire. Those who suffered from headaches were also examined by a neurologist. Complete data were available for 471 (90%) subjects. Thirty-four participants (7.2%) had CH. Two independent factors for association with CH could be identified: overuse of acute headache medication (OR = 72.5; 95% CI 25.9-202.9), and being a first-generation Turkish immigrant compared with native Germans (OR = 4.4; 95% CI 1.4-13.7). In contrast, the factor associated with chronic headache was not increased in second-generation Turkish immigrants. Medication overuse was significantly more frequent in first-generation Turkish immigrants (21.6%) compared with second-generation Turkish immigrants (3.3%) and native Germans (3.6%; X2 = 38.0, P < 0.001). First-generation Turkish immigrants did not contact headache specialists at all, compared with 2.8% of second-generation Turkish immigrants and 8.8% of native Germans ( X2 = 118.4, P < 0.001). Likewise no first-generation Turkish immigrant suffering from CH received headache preventive treatment, compared with 6.6% of native Germans ( X2 = 19.1, P = 0.014). The data from this cross-sectional study reveal a high prevalence of chronic headache as well as a very low utilization of adequate medical care in first-generation Turkish immigrants in Germany.

Abstract
OBJECTIVE Prostate cancer is among the most common cancers in males. Prostate cancer is androgen dependent in the beginning, but as time progresses, it becomes refractory to androgen deprivation treatment. At this stage, docetaxel has been used as standard treatment for years. Cabazitaxel has become the first chemotherapeutic agent which has been shown to increase survival for patients with metastatic Castrate Resistant Prostate Cancer (mCRPC) that progresses after docetaxel. Phase 3 TROPIC study demonstrated that cabazitaxel prolongs survival. PATIENTS AND METHODS In this study, we evaluated a total of 103 patients who took cabazitaxel chemotherapy for mCRPC diagnosis in 21 centers of Turkey, retrospectively. This study included patients who progressed despite docetaxel treatments, had ECOG performance score between 0-2, and used cabazitaxel treatment. Patients received cabazitaxel 25 mg/m2 at every 3 weeks, and prednisolone 5 mg twice a day. RESULTS Median number of cabazitaxel cures was 5.03 (range: 1-17). Cabazitaxel response evaluation detected that 34% of the patients had a partial response, 22.3% had stable disease and 32% had a progressive disease. Grade 3-4 hematological toxicities were neutropenia (28.2%), neutropenic fever (14.5%), anemia (6.7%), and thrombocytopenia (3.8%). In our study, median progression-free survival (PFS) was 7.7 months and overall survival (OS) was 10.6 months. CONCLUSIONS This study reflects toxicity profile of Turkish patients as a Caucasian race. We suggest that cabazitaxel is a safe and effective treatment option for mCRPC patients who progress after docetaxel. Moreover, ethnicity may play important roles both in treatment response and in toxicity profile.

Abstract
OBJECTIVES In this study, we aimed to evaluate whether an association exists between complete blood count (CBC) parameters and bone mineral density (BMD) in elderly females with type 2 diabetes mellitus (T2DM) and to estimate the differences in BMD in T2DM. METHODS The medical records of female patients who had been referred for BMD analysis to a tertiary hospital in Ankara, Turkey were reviewed. RESULTS A total of 275 women (66 with T2DM, 209 without T2DM; mean age 72.1 ± 5.4 years) were included in study. White blood cell (WBC) counts, lumbar spine BMD (LSBMD) and femoral neck BMD (FNBMD) were found to be significantly higher in T2DM. There was an inverse association between haematocrit (Hct) and LSBMD in diabetic group (r = - 0.330; P = 0.008). CONCLUSION Diabetic patients had higher BMD levels. Regardless of the mechanisms, Hct could be a readily available potential candidate to identify diabetic patients with osteoporosis.

Abstract
OBJECTIVES Palonosetron is a novel 5-hydroxytryptamine(3) (5 HT(3)) receptor antagonist, which has been shown to be superior to first generation 5 HT(3) receptor antagonists regarding the prevention of acute, delayed and overall chemotherapy-induced nausea and vomiting. First generation 5 HT(3) receptor antagonists may induce electrocardiographic changes of heart rate and repolarization. The acute cardiac effect of palonosteron is unknown. The purpose of this study is to determine acute effects of palonosetron on electrocardiographic (ECG) parameters in cancer patients. MATERIALS AND METHODS The study had a prospective design. Seventy-six cancer patients with normal cardiac function who received palonosetron for prevention of chemotherapy-induced nausea and vomiting were enrolled. Standard 12-lead ECG recordings were performed at baseline and 30 min after palonosetron administration. P wave durations and corrected QT intervals were measured; P wave dispersion (Pd) and QTc dispersion were calculated. RESULTS Median heart rate did not differ among 76 patients enrolled before and after palonosetron administration (p: 0.6). Systolic and diastolic blood pressures were not significantly different before and after palonosteron (p values 0.9 and 0.3, respectively). Although median QT min value was higher after palonosetron administration than before palonosetron administration, the difference was not statistically significant (p: 0.6). CONCLUSION Palonosetron seems to have no acute arrhythmogenic potential.

Abstract
A prospective, randomised and single blind clinical trial was designed to compare intravenous methylprednisolone pulse (IVGC) with oral methylprednisolone (OGC) monotherapy in terms of effectiveness and tolerability in Graves' ophthalmopathy (GO). Fifty-two consecutive patients with untreated, moderately severe and active GO were randomly treated with either IVGC or OGC therapy for 12 weeks. IVGC therapy achieved a more rapid and significant improvement than OGC therapy according to clinical activity score (p < 0.01), proptosis (p < 0.038), lid width (p < 0.0001), extraocular muscle changes (p < 0.02), optic neuropathy. (p < 0.001), intraocular pressure (p < 0.04), visual acuity (p < 0.03), quality of life (p < 0.0001) and treatment response (p < 0.001). Diplopia was significantly improved in two groups but there was no difference between them (p < 0.6). Heavy smokers indicated alteration of ophthalmic signs with increased thyroid stimulating hormone (TSH)-receptor antibody during the therapy. In conclusion, IVGC therapy was more effective and better tolerated than OGC therapy in the management of GO.

Abstract
The aim of the study was to investigate the frequency of silent myocardial ischemia in type 2 diabetic patients without any clinical or laboratory findings of myocardial ischemia and to examine the related factors for silent myocardial ischemia. A total of 116 type 2 diabetic patients (82 women) with a disease duration of 5-20 years were included in the study. All patients underwent stress and resting myocardial perfusion single-photon emission computed tomographic (SPECT) study with (99m)Tc-MIBI. Coronary angiography was performed in patients with ischemia established at myocardial perfusion SPECT. Ischemia was determined in 18 (15.5%) patients by myocardial perfusion SPECT. Coronary angiography performed in 17 of these patients confirmed coronary stenosis >50% in 11 patients. Thus, the prevalence of silent myocardial ischemia was 9.6%. Significant relations were found between silent myocardial ischemia and male sex, high HbA(1C) level and retinopathy. Type 2 diabetic patients (especially men) with poorly controlled diabetes mellitus or retinopathy should be screened for silent myocardial ischemia.

Abstract
This report describes the first Turkish family to be diagnosed with Bernard-Soulier syndrome. The family consists of nine members (two parents, three sons and four daughters). The parents were first cousins. The index case, a 22 year-old-man, had a history of haemorrhagic diathesis with thrombocytopenia, giant platelets in the peripheral blood smear and a prolonged bleeding time. Refractory idiopathic thrombocytopenic purpura had been diagnosed elsewhere and a splenectomy had been performed six months previously. Ristocetin agglutination of platelets was defective and flow cytometry analysis of platelet membrane glycoprotein showed markedly reduced expression of glycoprotein lb (2.1%). Bernard-Soulier syndrome was diagnosed. Increased mean platelet volume was found in both parents, one son and three daughters. The other son and daughter were normal.

Abstract
It has been suggested that an insertion/deletion (I/D) polymorphism in intron 16 of the angiotensin-converting enzyme (ACE) gene may be associated with diabetic nephropathy The aim of this study was to investigate whether an association exists between ACE I/D polymorphism and glomerular filtration rate (GFR) in type 2 diabetes mellitus. A total of 128 type 2 diabetic patients were included in the study with the following ACE genotype distribution: DD 40, ID 58,11 30. I/D polymorphism was determined by polymerase chain reaction (PCR). Mean GFR was not statistically different according to ACE genotype (DD: 89.9 +/- 28.1 ml/min, ID: 99.5 +/- 25.1 ml/min, II: 96.6 +/- 19.6 ml/min). There was no significant difference in genotype distribution in normo-, micro- and macroalbuminuric patients (DD:ID:II [%], normo- 35:46:19, micro-28:55:17, macro- 31:55:14). ACE I/D polymorphism does not seem to be associated with GFR in type 2 diabetic patients.

Abstract
The aim of this study was to investigate the prevalence of hepatitis B and hepatitis C virus infections in type 2 diabetic patients in Gaziantep, Turkey. Six hundred and ninety-two type 2 diabetic patients and 1014 healthy blood donors were included in the study. No significant difference was found between type 2 diabetic patients and the control group for seropositivity of HBsAg (5.3% vs 5.1%, p>0.05). In contrast, anti-HCV was significantly more frequent in type 2 diabetic patients (7.5% vs 0.1%, p>0.0001). We found no significant difference for HBsAg seropositivity between type 2 diabetic patients with a disease duration of 12 months or less, but anti-HCV seropositivity was significantly more frequent in diabetic patients with a longer disease duration (p<0.05). We suggest that HCV infection is not a trigger factor for type 2 diabetes mellitus but is frequently associated with it.

Abstract
The aim of this study was to investigate whether an association exists between the angiotensin converting enzyme (ACE) insertion/deletion (I/D) polymorphism and microvascular complications of type 2 diabetes mellitus in Turkish patients. A total of 239 type 2 diabetic patients and 138 sex and age matched control subjects were included into the study. The I/D polymorphism was determined by polymerase chain reaction (PCR). Nephropathy status was determined according to urinary albumin/creatinine ratio (microg/mg) (<30 normoalbuminuria, 30-300 microalbuminuria, >300 macroalbuminuria) and retinopathy was evaluated by fundoscopic examination and by flourescein fundus angiography. The distribution of ACE I/D polymorphism and allele frequencies in diabetic patients were not significantly different from controls, DD genotype 32.2 versus 37.2%; ID genotype 50.6 versus 47.1%; and II 17.2 versus 15.2%; D allele 57.5 versus 61.2%; I allele 42.5 versus 38.8%. Genotype distribution between normo-, micro- and macroalbuminuric patients did not differ significantly (DD:ID:II (%), normoalbuminuria, 35:46:19; microalbuminuria, 28:55:17; macroalbuminuria, 31:55:14). There was also no difference in genotype distribution between patients with and without retinopathy (DD:ID:II (%), retinopathy positive, 32:51:17; retinopathy negative, 33:49:18). In conclusion, the ACE I/D polymorphism does not seem to be associated with diabetic nephropathy and retinopathy in Turkish type 2 diabetic patients.

Abstract
It has been suggested that an insertion/deletion (I/D) polymorphism in intron 16 of the angiotensin converting enzyme (ACE) gene may be associated with essential hypertension. The aim of this study was to examine the association between ACE I/D polymorphism with blood pressure level and hypertension status in Turkish type 2' diabetic subjects. Hundred and seven hypertensive (78 female, 29 male) and 132 normotensive type 2 diabetic subjects (73 female, 59 male) and 138 sex and age matched control subjects (87 female, 51 male) without diabetes and hypertension were included into the study. The I/D polymorphism was determined by polymerase chain reaction (PCR). There were no statistically difference in genotypic and allelic frequencies of the ACE I/D polymorphism between the hypertensive and normotensive diabetic patients and control subjects. Also no significant differences was detected in systolic and diastolic blood pressure among three different genotypes. ACE I/D polymorphism does not seem to play an important role in the development of hypertension in Turkish type 2 diabetic subjects, but prospective studies may show an association between ACE gene polymorphism and the development of hypertension in diabetic subjects.
