Abstract
OBJECTIVE The majority of patients with papillary thyroid carcinoma (PTC) have good outcomes, although the identification of new predictors of a poor prognosis would be beneficial. Chronic thyroiditis is a precancerous condition in which proinflammatory cytokines enhance biologically aggressive features. This study investigated the expression of suppressor of cytokine signaling proteins (SOCS) 1 and 3, which are negative feedback inhibitors, in PTC and benign thyroid nodules (BTN), and analyzed the relations among biomarker expression, pathological prognosis, and clinical features. PATIENTS AND METHODS The pathological materials and clinical data of 100 patients with PTC and 40 with BTN were retrospectively analyzed. Immunohistochemical SOCS1 and SOCS3 staining were performed. Besides comparing SOCS1 and SOCS3 expression between PTC and BTN, we analyzed the expression according to pathological factors and clinical variables. RESULTS The expression levels of the proteins were significantly higher in PTC than in BTN (p=0.001). SOCS1 expression was higher in older patients with PTC than in younger patients (p=0.001). Unlike SOCS1, SOCS3 was related to the risk group; these groups were distinguished based on the American Thyroid Association (ATA) risk stratification system (p=0.001). SOCS3 was also significantly related to lymph node involvement (p=0.007), capsule invasion (p=0.005), and extrathyroid extension (p=0.009). CONCLUSIONS The increased SOCS1 and SOCS3 expression in PTC confirms their roles in thyroid carcinogenesis. Antibodies to both SOCS1 and SOCS3 might aid the diagnosis of PTC through immunohistological staining. SOCS3 provides information on lymph node status and aids risk stratification.

Abstract
AIM Is to evaluate the influence of glucovance therapy on biomechanical properties of bone in streptozotocin - induced diabetes mellitus (DM) in rats. MATERIALS AND METHODS A total of 28 male Wistar-Albino rats (12-week-old; 210-300 g) were divided into 4 groups including control (C; no treatment; n=7), sham [Sh; distilled water (gavage, for 8 weeks); n=7], diabetes [DM; streptozotocin (45 mg/kg, single i.p injection); n=7] and diabetes+ Glucovance treatment [DM+G; streptozotocin (45 mg/kg, single i.p injection) + Glucovance (Glucovance, 500/5 mg/kg/day/rat, gavage, for 8 weeks); n=7] groups. Body weight, blood glucose levels (BGLs), bone mineral density (BMD) and geometric/mechanical properties of bone tissue were evaluated. BGLs in diabetic rats were significantly increased compared to non-diabetic rats, while the body weights were decreased (p<0.05). RESULTS A significant difference was not detected between groups with regard to cross-sectional area of diaphyseal femur (p>0.05). Maximum load, energy absorption capacity, ultimate stress, ultimate strain, toughness and displacement were shown to decrease and stiffness was shown to increase in DM rats (p<0.05). Ultimate stress and maximum load were significantly increased in DM+G groups compared to DM groups (p<0.05). CONCLUSION Glucovance treatment seems to be effective in restoration of biomechanical deterioration of bone specific to STZ-induced DM.

Abstract
INTRODUCTION Medical and surgical treatment options are available for patients with diabetic foot ulcers. In more severe cases, amputation decisions are determined by patient comorbidities, performance, imaging studies, and clinical examination results. However, an objective indicator that predicts how this amputation process will end has not yet been clarified. This study identifiies clinical characteristics that can be predictors of the need for diabetic foot amputation among patients. METHODS In this retrospective observational study, a total of 400 patients with type 2 diabetes who were over the age of 18 and possessed diabetic foot ulcers were examined. The clinical, radiological, and scintigraphic profiles of these patients including age, gender, duration of diabetes, smoking history, previous diabetic foot amputation, presence of hypertension (HT), coronary artery disease (CAD), peripheral artery disease (PAD), cerebrovascular disease, cardiovascular disease, retinopathy, neuropathy and nephropathy were analyzed. RESULTS Of the 400 patients with diabetic foot ulcers, 143 (35.75%) underwent foot amputation. Moreover, the frequency of proteinuria in amputees was significantly higher than in non-amputees (p<0,05). Amputees also exhibited significantly longer smoking histories (p<0,001), and the frequency of reamputation was significantly higher in those who possesed histories of previous amputation (p=0.038). After multivariate analysis PAD presence and previous diabetic ulcer history were the significant factors to determine the amputation decision. CONCLUSION The following patient characteristics were determined as being effective for predicting the need for amputation: male sex, CAD, PAD, HT, proteinuria, ulcers with Wagner Stages 4-5, smoking histories, previous diabetic ulcer histories, and previous amputation histories. The specificity of the model with these variables was determined as 86% in the patients who did not need amputation. Significant determinants were peripheral artery disease presence and diabetic foot ulcer history. Still, further and more extensive research with higher numbers of patients is necessary for determining more precisely the need for amputation.

Abstract
OBJECTIVE The aim of the present study is to evaluate the effects of methimazole (MTZ) and propylthiouracil (PTU) treatments on osteopontin (OPN) and oxidative stress in Graves' disease (GD). MATERIAL AND METHODS The study included 60 cases with GD in hyperthyroid state and taking no antithyroid treatment, and 30 healthy volunteers. GD patients were randomly separated into two groups; 30 of them took PTU, and the other 30 took MTZ treatments. Blood samples were taken from the patients with GD before the treatment, and three months after the treatment was begun, when they were in the euthyroid state; blood samples of the healthy control subjects were also taken at these times. RESULTS TAS and OSI levels before treatment were significantly higher in the GD group, when compared to the control group (p<0.001, for each). GD subjects taking PTU treatment had significantly higher TAS levels (p=0.001), and significantly lower TOS and OSI levels (p=0.008 and p=0.001, respectively). TAS levels significantly decreased in the patients taking MTZ treatment (p=0.029), but TOS and OSI levels did not change significantly (p>0.05). Pretreatment OPN levels were significantly higher in GD patients, when compared to the control group (p=0.014). OPN level significantly decreased in the GD group taking PTU treatment; however OPN levels in the group taking MTZ treatment did not change significantly when compared to the pretreatment value. CONCLUSION PTU treatment is more effective in decreasing OPN and oxidative stress in GD patients, when compared to the MTZ treatment.

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
OBJECTIVE The aim of this study is to determine the changes involving auditory system in cases with acromegaly. MATERIALS AND METHODS Otological examinations of 41 cases with acromegaly (uncontrolled n = 22, controlled n = 19) were compared with those of age and gender-matched 24 healthy subjects. Whereas the cases with acromegaly underwent examination with pure tone audiometry (PTA), speech audiometry for speech discrimination (SD), tympanometry, stapedius reflex evaluation and otoacoustic emission tests, the control group did only have otological examination and PTA. Additionally, previously performed paranasal sinus-computed tomography of all cases with acromegaly and control subjects were obtained to measure the length of internal acoustic canal (IAC). RESULTS PTA values were higher (p < 0.001 for right ears and p = 0.001 for left ears), and SD scores were (p = 0.002 for right ears and p = 0.002 for left ears) lower in acromegalic patients. IAC width in acromegaly group was narrower compared to that in control group (p = 0.03 for right ears and p = 0.02 for left ears). When only cases with acromegaly were taken into consideration, PTA values in left ears had positive correlation with growth hormone and insulin-like growth factor-1 levels (r = 0.4, p = 0.02 and r = 0.3, p = 0.03). Of all cases with acromegaly 13 (32%) had hearing loss in at least one ear, 7 (54%) had sensorineural type and 6 (46%) had conductive type hearing loss. CONCLUSION Acromegaly may cause certain changes in the auditory system in cases with acromegaly. The changes in the auditory system may be multifactorial causing both conductive and sensorioneural defects.

Abstract
The present study aimed to evaluate the infiltration of macrophages in form of crown-line structures (CLS) in subcutaneous adipose tissue (SAT) of obese individuals, and to investigate the effect of these on both metabolic parameters and adipose tissue 11-beta-hydroxysteroid dehydrogenase type 1 (11BHSD1) enzyme levels. A total of 53 obese (10 men, 43 woman) enrolled in the study. Body mass index (BMI), waist circumference (WC), hip circumfrence, and systolic (SBP) and diastolic blood pressures (DBP) of all subjects were recorded. Insulin resistance was determined using the homeostasis model assessment (HOMA). The concentration of SAT, tumor necrosis factor (TNF)-α, interleukin (IL)-6, 11BHSD1 were performed by enzyme-linked immunosorbent assay (ELISA) method. The infiltration of macrophages in form of CLS in adipose tissue were determined using cell-specific stains against CD68. There was no significant difference between the CLS+group and the CLS- group in terms of age, gender, BMI, WC, waist-to-hip circumference ratio (WHR), SBP and DBP levels. Fasting plasma glucose (FPG), HOMA-IR, insulin and SAT TNF-α levels were higher in the CLS+group compared to the CLS- group. FPG and SAT TNF-α levels were significantly higher in participants with high CLS density compared to participants with low density CLS. SAT 11BHSD1 levels was significant higher in the CLS+group compare to the CLS- group and in the high CLS density group compared to the low density group. In conclusion, the infiltration of macrophages in the form of CLS in SAT is associated with increased 11BHSD1 levels. It may be an important mechanism in the development of metabolic disorders.

Abstract
The present study aimed to evaluate the role of subcutaneous adipose tissue (SAT) type II deiodinase enzyme gene (DIO2) expression in developing metabolic syndrome (MetS). A total of 51 obese patients with MetS and without MetS and 13 healthy subjects enrolled in the study. Body mass index (BMI), waist circumference (WC), waist-to-hip circumference ratio (WHR), hip circumference, and systolic (SBP) and diastolic blood pressures (DBP) of all subjects were recorded. Fasting plasma glucose (FPG), fasting plasma insulin, high density lipoprotein- cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), total cholesterol (TC) and triglyceride (TG) of all subjects were analyzed. Expression of the DIO2 gene in adipose tissue was determined by reverse transcription polymerase chain reaction (qRT-PCR). BMI, WC and WHR were not significantly difference between obese with and without MetS. SBP, DBP, FPG and TG were significantly higher in obese with MetS group than obese without MetS group. While the free triiodothyronine (T3) level was in the normal range in all group, it was significantly lower in the obese with MetS than both obese without MetS and control group. DIO2 expression was significantly lower in the obese with MetS group compared to the control. In correlation analysis, DIO2 expression was negatively correlated with DBP, TG and homeostasis model assessment of insulin resistance (HOMA-IR) levels and positively correlated with free T3. In conclusion, the reduction of SAT DIO2 expression is negatively correlated with DBP and TG levels that are associated with the MetS. This might have an effect on developing MetS. We believe that DIO2 gene may be an important molecular target for future studies in developing targeted treatment options for obese people with MetS.

Abstract
The present study aimed to evaluate the activity of prolidase in controlled acromegaly patients and its association with oxidative stress. 25 acromegalic patients in remission who were followed in our outpatient clinic and 31 healthy controls were enrolled in the study. Serum growth hormone (GH), insulin-like growth factor 1 (IGF-1), total antioxidative status (TAS), total oxidative stress (TOS), total free sulfhydryl (-SH), paraoxonase (PON), arylesterase (ARE), lipid hydroperoxide (LOOH) and prolidase activity levels were measured. Percent ratio of TOS to TAS level was accepted as oxidative stress index (OSI). Serum prolidase activity, TOS, OSI, and LOOH levels were significantly higher in acromegaly patients compared to the healthy control group (p<0.001, p=0.001, p<0.001, and p<0.001, respectively). SH levels were significantly lower in the acromegaly patients compared to the healthy control group (p=0.002). Prolidase activity were positively correlated with TOS, OSI, LOOH and negatively correlated with -SH in patients with acromegaly (r=0.471, p<0.001; r=0.527, p<0.001; r=0.717, p<0.001; r=- 0.516, p<0.001, respectively). These associations were confirmed in the multiple regression analysis (R(2)=0.502, p<0.001). In conclusion, serum prolidase activity and oxidative stress levels were high in controlled acromegaly patients. These results suggest that extracellular matrix changes continue eventhough the disease is controlled, and elevated oxidative stress is involved in the increased prolidase activity in acromegaly patients.

Abstract
OBJECTIVE The aim of this study was to evaluate serum prolidase levels and its association with oxidative stress in autoimmune thyroid disease (AITD). MATERIALS AND METHODS 25 with Hashimoto thyroiditis (HT) and 25 patients Graves' disease (GD), and 27 healthy controls were enrolled in the study. The patients with signs of Graves' ophthalmopathy were excluded from the study. Serum samples were obtained in euthyroid period at the third month of treatment. Serum prolidase, total antioxidant status (TAS), total oxidative stress (TOS), and total free sulfhydryl (-SH) levels were measured. RESULTS Serum prolidase levels were significantly higher in the patients with GD compared to the HT and the healthy control group. Oxidative stress index (OSI) and TOS levels of the patients with both GD and HT were significantly higher compared to those of the control group (p < 0.001, for each), while -SH levels were significantly lower (p < 0.001, for each). There was no significant difference between the patients with HT and healthy control group in terms of prolidase levels (p = 0.580). Prolidase levels were positively correlated with TOS and OSI and negatively correlated with -SH (r = 0.565, p = 0.003; r = 0.604, p = 0.001; r = -0.532, p = 0.006). CONCLUSION Serum prolidase activity is increased in GD patients without signs of ophthalmopathy, and showed a positive correlation with oxidative stress parameters.

Abstract
The aim of this study was to evaluate serum calprotectin levels and oxidative stress status in patients with papillary thyroid carcinoma (PTC) and the changes in their levels after total thyroidectomy. The study involved 30 patients with PTC and 30 healthy controls. Blood samples were obtained from the PTC patients before and 1 month after the operation. Preoperative and postoperative serum samples from PTC patients and healthy controls were analysed for calprotectin, total antioxidant status (TAS), total oxidant status (TOS) and lipid hydroperokside (LOOH). The preoperative calprotectin, TOS, OSI and LOOH levels of the patients with PTC were significantly higher compared to those of the control group (p < 0.001, for each). The levels of calprotectin decreased significantly in patients with PTC after the operation (p < 0.001), while TAS, TOS and OSI levels remained unchanged (p = 0.313, p = 0.085 and p = 0.163, respectively). Preoperative serum calprotectin levels were positively correlated with TOS, OSI and LOOH levels and negatively correlated with TAS levels in patients with PTC. In conclusion, serum calprotectin levels is increased in patients with PTC, and calprotectin is positively correlated with TOS and LOOH. Serum calprotectin levels is significantly decreased after total thyroidectomy.

Abstract
OBJECTIVE This study was performed to identify the relationship between the quality of life and polyneuropathy which is one of the complications of diabetes. METHODS Total 111 patients with diabetes mellitus were taken into the study as type 1 and type 2. Patients were accepted having polyneuropathy according to their electroneuromyography (ENMG) results. To evaluate the quality of life in the patients Short Form 36 (SF-36) and World Health Organization Quality of Life Questionnaire abbreviated version (WHOQOL-BREF) were used. RESULTS Clinical polyneuropathy was found in 46% of the patients, while polineuropathy was found in 63% of the patients with evaluation ENMG. The patients with polyneuropathy had poor quality of life according to SF-36 and WHOQOL-BREF (p < 0.001). The mean quality of life scores of patients who had sensoriomotor and mix polyneuropathy, were lower than sensory type and axonal polyneuropathy. CONCLUSION Diabetic polyneuropathy influences the quality of life in a negative way. The quality of life scores of patients who had polyneuropathy continuing with mixed pathogenesis and sensoriomotor type, become worse for this reason, even if the patients do not have any clinical polyneuropathy, this being evaluated with ENMG.

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
OBJECTIVE The aim of the present study was to investigate any relationship between serum ubiquitin levels and electroneurographic changes in peripheral nerves for patients with type 2 diabetes. RESEARCH DESIGN AND METHODS The study involved 34 patients (19 men, 15 women; mean age 46 +/- 13 years) with type 2 diabetes. Serum ubiquitin values were measured by sandwich enzyme-linked immunosorbent assay Measurement of nerve conduction velocity (NCV) was performed on three motor (median, tibial, and peroneal) and three sensory (median, ulnar, and sural) nerves. The value of motor compound muscle action potential (CMAP) was obtained from the sum of median, tibial, and peroneal motor nerve amplitudes, and sensory compound nerve action potential (CNAP) was computed as the sum of median and ulnar sensory nerve amplitudes. RESULTS Patients with diabetes were divided into three groups: group 1 (n = 8) had normal electroneurography results, group 2 (n = 8) had slowed NCV, and group 3 (n = 18) had low values of motor CMAP and/or sensory CNAP as well as slowed NCV. Mean ubiquitin level in group 3 (20.4 +/- 2.9 ng/dl) was significantly higher than that in group 1 (11.2 +/- 1.1 ng/dl, t = 11.5, P < 0.0001) and group 2 (13.2 +/- 2.7 ng/dl, t = 5.9, P < 0.0001). Serum ubiquitin levels were inversely correlated with motor CMAP (r = -0.68) and sensory CNAP (r = -0.61) values. CONCLUSIONS The results of this study indicate that there could be a relationship between the diminished amplitudes of axons of the peripheral nerve and the increase in serum ubiquitin levels in patients with type 2 diabetes. Further studies are required to confirm this relationship.

Abstract
In this study, the normal hematological values in healthy adults living in Erzurum area in Turkey at moderate altitude (1869 m above sea level), and the effect of moderate altitude on these hematological values was investigated. The study population comprised of 929 females and 1204 males aged between 17-95. The mean values for red blood cell and leukocyte counts, and hemoglobin level were significantly higher in males than in females (p<0.0001), whereas platelet count was significantly higher in females than in males (p<0.0001). ›n conclusion, we could not find an increase in the number of red blood cells as well as other hematological parameters in healthy adults living in Erzurum area. Hematological values in this study were similar to those reported in the previous studies carried out with those living under 1869 m.

Abstract
In haemodialysis (HD) patients, functional iron deficiency frequently appears due to recombinant human erythropoietin (r-HuEPO) treatment. However, the diagnosis of iron deficiency is not always easy in such patients. Recent studies have shown that the serum transferrin receptor (s-TfR) level is a sensitive, quantitative measure of tissue iron deficiency. In this study, we examined the changes in s-TfR levels in patients with iron deficiency anaemia due to r-HuEPO treatment. We compared s-TfR levels of 24 patients with i.v. administered r-HuEPO (50-70 U/kg/dose) at the end of each dialysis session (three times a week) and diagnosed as having iron deficiency anaemia by routine laboratory methods (ferritin <50 microg/l and transferrin saturation <16%) with s-TfR levels of 32 patients not receiving r-HuEPO and without iron deficiency anaemia. Also, 40 healthy volunteer subjects were included in the study as a control group. Serum ferritin and transferrin receptor levels were measured with ELISAs using monoclonal reagents. There were no differences between the two groups with and without iron deficiency anaemia with respect to mean age, body weight, haemodialysis duration, haemoglobin and serum creatinine levels (p>0.05). For s-TfR levels, while no difference was present between the control and the non-iron deficiency groups (p>0.05), the iron deficiency group had higher s-TfR values than those of both the control and non-iron deficiency groups (p<0.001). Besides, there was an inverse correlation between haemoglobin and s-TfR levels in patients with iron deficiency anaemia (r = -0.85, p<0.0001). We conclude that the measurement of s-TfR levels may be useful in the diagnosis of functional iron deficiency in haemodialysis patients receiving r-HuEPO.
