Abstract
OBJECTIVE Behçet's Disease (BD) is a chronic multisystem vasculitis that manifests with destructive inflammation affecting the eyes, central nervous system, and blood vessels. The pathology of vein involvement in BD is poorly characterized. Magnetic resonance (MR) venography gives more comprehensive information about deep veins and adjacent tissues. In this study, we aimed to characterize vein involvement and evaluate the diagnostic utility of MR venography in BD. METHODS Sixty-five BD patients who fulfilled the International Study Group (ISG) criteria and 20 healthy control subjects were enrolled. Inferior vena cava (IVC), common iliac veins (CIV), external (EIV) and internal iliac veins (IVV), common femoral veins (CFV), femoral veins (FV), and greater saphenous veins (GSV) of BD patients and healthy controls were evaluated with MR venography and ultrasonography for the presence pathologic features, luminal thrombi, vessel wall changes, and perivascular abnormalities. RESULTS 33 vascular and 32 non-vascular BD patients (mean age 39.3 ± 11.3 years and 48 [73.8%] male) were enrolled. MR venography revealed diffuse concentric thickening of the walls of IVC, CIV, EIV, IIV, CFV, FV, and GSV in BD (healthy controls vs. BD p<0.05 for all vein segments). MR venography provided additional information about veins and perivascular tissues like contrast enhancement, enlarged lymph nodes, and seminal vesicle vascularization, which were remarkably more frequent in vascular BD than non-vascular BD and healthy controls. CONCLUSION The results of our study suggest that the involvement of the venous system is diffuse and generalized in BD, and demonstration of venulitis might help diagnose the disease.

Abstract
BACKGROUND IgG4- related disease (IgG4- RD) is a systemic fibroinflammatory disease whose pathogenesis has not been completely elucidated. Due to the novelty and complexity of the diagnostic criteria, it is difficult to distinguish from the diseases included in the differential diagnosis without tissue biopsy. This study aimed to discover new biomarkers that can help for disease diagnosis and its differential diagnosis by reviewing the relationships between neutrophil-lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI). METHODS Thirty IgG4- RD, 38 granulomatous polyangiitis (GPA), and 46 sarcoidosis patients presenting to the Rheumatology Clinic meeting the criteria of 2019 American College of Rheumatology, 2012 International Chapel Hill and 1999 American Thoracic Society meeting, respectively, and 27 healthy control subjects were included. We collected data on complete blood count with automated differential values including NLR, PLR, SII, and SIRI. RESULTS The SII and PLR values were significantly higher in patients with IgG4-RD compared to healthy controls, (SII median (minmax) 572 (102-5583) vs. 434 (172-897), PLR median (min-max) 130 (56.8-546) vs. 104 (57.5- 253) p < 0.001). SII value was found to have a significant positive correlation with CRP in IgG4-RD disease (r = 0.371; p = 0.043). While SII, SIRI, NLR, PLR parameters were not significant between the IgG4-RD and sarcoidosis groups, SII, SIRI, NLR, PLR were significantly higher in patients with GPA than in IgG4-RD patients (p < 0.001). DISCUSSION This is the first study to review the SII, SIRI, NLR, and PLR in IgG4-RD. The obtained results suggest that the SII could beused as a new tool, for differential diagnosis and activity of the IgG4-RD.

Abstract
BACKGROUND We aimed to determine the effect of blood lactate levels on cardiovascular (CV) death and hospitalization for heart failure (HF) in acute HF patients with reduced left ventricular ejection fraction (EF). METHODS Eighty-five acute HF patients with reduced ejection fraction were divided into two groups according to admission blood lactate levels. 48 of them had low blood lactate levels (< 2 mmol/l) and 37 of them had high blood lactate levels (≥ 2 mmol/l). Patients with acute coronary syndrome, cardiogenic shock, sepsis and low blood pressure at admission were excluded from the study. Primary endpoint is the composite of cardiovascular (CV) death and hospitalization for heart failure (HHF) in 6-month follow-up. Secondary endpoint is the change in NT-proBNP levels from admission to 72 h. RESULTS Baseline characteristics of patients were similar in two groups. On baseline echocardiographic evaluation; patients with high lactate revealed a higher mitral E/A ratio (2.34 [0.43-3.31], p = 0.008) and a lower TAPSE ratio (14 [10-27], p = 0.008) than patients with low lactate levels. Over a median follow-up period of 6 months, the primary end point occurred in 28 (75.7%) of 37 patients assigned to high lactate group and in 20 (41.7%) of 48 patients assigned to low lactate group (p = 0.006). High lactate levels significantly increased the risk of CV death and HHF at 6 months by nearly 5.35-fold in acute HF patients with reduced EF. The change in NT-proBNP levels at 72nd hour after admission were similar between two groups. CONCLUSION Higher lactate levels at admission related with higher HHF at 6 months and may be related with higher risk of CV death in acute HF patients with reduced EF.

Abstract
Hydatid disease is a parasitic infection caused by Echinococcus granulosus characterised by cyst formation in various organs. The liver is the most commonly involved organ. Hydatid disease is endemic in many parts of the world and its prevalence is also high in the Mediterranean region including Turkey. Uncomplicated liver cysts may stay asymptomatic for a long time. Hydatid cysts can rupture either spontaneously or following trauma. Anaphylaxis is an acute, life-threatening medical emergency with many potential triggers. The rupture of hydatid cysts caused by sports trauma is very rare and can lead to anaphylactic reactions and fatal anaphylaxis. We described a patient who was previously unknown to have hydatid disease being treated in the emergency setting following a sports trauma.

Abstract
BACKGROUND The aim of this study is to evaluate the effect of Ramadan intermittent fasting on metabolic markers, dietary intake, anthropometric measurements, and abdominal visceral fat thickness (VFT) in pregnancy. METHODS Seventy-eight healthy pregnant subjects who had fasted for at least 15 days during the month of Ramadan in 2012 and 2013 and 78 controls were included in this study. Metabolic markers, dietary intake, anthropometric measurements, and ultrasonographic VFT were calculated for each subject before and after Ramadan fasting. RESULTS When before and after Ramadan values in the fasting group were compared, we found that daily protein intake was increased (p <0.001), but fat and carbohydrate intake remained unchanged. A significant reduction was observed in liquid consumption while the frequency of asymptomatic bacteriuria was increased. High-density lipoprotein significantly increased, and glycated hemoglobin, insulin, and homeostasis model index significantly decreased (p =0.005, p =0.01, p <0.001, and p =0.03, respectively). A significant increase in ferritin was found (p =0.02). No change was observed in subcutaneous fat thickness, while VFT significantly decreased (p =0.08, p =0.005). However, in the control group, only ferritin level increased. CONCLUSION A combined change in the number and timing of meals and the portioning of the entire daily intake into only two meals per day may have beneficial metabolic effects and reduction in VFT during pregnancy.

Abstract
Bisphosphonates are inorganic pyrophosphate analog which accumulate on the bone surface, cause osteoclast apoptosis, and inhibit bone resorption. The nitrogen-containing bisphosphonates continue to be the drug of choice for the treatment of osteoporosis in both men and women. Although histomorphometric studies including bone biopsies have not shown any evidence of microcracks, recent studies have revealed that potent bisphosphonates are responsible for the oversuppression of bone turnover leading to microdamages, reduced bone strength, and increased fracture risk. There are individual cases reporting atypical femoral fractures and severely suppressed bone turnover along with long-term (≥ 5 years) use of biphosphonates. In this study, we report on a 74-year-old woman with a history of continuous alendronate use for nearly 16 years who presented to the emergency department with right proximal humerus and left femur fracture.

Abstract
OBJECTIVE Several studies have shown increased oxidative stress in patients with pre-diabetes and newly diagnosed Type 2 diabetes mellitus (T2DM). It has been proposed that oxidative stress initiates insulin resistance in genetically predisposed individuals. The aim of this study was to evaluate the markers of oxidative stress in the offspring of patients with T2DM. MATERIAL AND METHODS We examined 60 lean normoglycemic offspring of Type 2 diabetics, and 52 age, sex and body mass index matched subjects without family history of T2DM as controls. Anthropometric, biochemical and carotid intima media thickness (IMT) measurements and oral glucose tolerance test (OGTT) were performed. Erythrocyte superoxide dismutase and glutathione peroxidase activities, serum nitric oxide, plasma total sulfhydryl (tSH) groups, plasma total antioxidant status, plasma malondialdehyde and serum 8-hydroxydeoxy-guanosine (8-OHdG) levels were compared between 2 groups. RESULTS 2 groups were similar for the measurements of anthropometric, blood pressure, lipids, fasting glucose, HOMA-IR and carotid IMT. Glucose levels during OGTT were significantly higher in the offspring of Type 2 diabetics than controls (p=0.035). The offspring of Type 2 diabetics showed a significant increase in serum 8-OHdG level (p=0.005) and plasma tSH groups (p=0.032) when compared to the controls. Significant differences were not obtained in other oxidative stress marker levels between 2 groups. CONCLUSION Main finding of our study was the presence of increased oxidative DNA damage in lean normoglycemic offspring of Type 2 diabetic patients. There is a need for further clinical studies in order to explain whether oxidative stress is present in genetically predisposed subjects and induces the insulin resistance.

Abstract
Tissue macrophage accumulation is thought to induce insulin resistance during obesity and stimulate the progression of diabetic nephropathy (DN). The objective of this study was to investigate genotypic and allelic frequencies of monocyte chemoattractant protein-1 (MCP-1) gene polymorphism in the healthy and patients with and without DN. The MCP-1 genotypes were determined in 43 patients with nephropathy and 43 without nephropathy and a control group of 105 healthy individuals. The genotype MCP-1 (-2518G/A) distribution did differ between the control group and the type 2 diabetic patients (P = 0.004). The frequency of the polymorphic G allele was also no similar for the group with type 2 diabetes as for the control group with 20.9 and 32.4%, respectively (P = 0.012). The AA genotype and A allele at MCP-1 -2518 was an independent risk factor for the progression of type 2 diabetes. In conclusion, MCP-1 AA genotype and A allele may play a specific role(s) in determining diabetic susceptibility, but do not seem to be important in the clinical manifestations of DN.

Abstract
We aimed to evaluate the relationship between 174 promoter region of the interleukin-6 (IL-6) C/G gene polymorphism and high sensitive C-reactive protein (hs-CRP), fibrinogen and carotis intima-media thickness (CIMT), body mass index, homeostatic model assessment (HOMA) insulin resistance index, serum lipid parameters, in polycystic ovary syndrome (PCOS) patients carrying a potential risk for developing cardiovascular disease (CVD). We studied 88 PCOS patients and 119 healthy controls. PCOS was defined by the Rotterdam PCOS consensus criteria. The genotype IL-6 distribution did differ between the control group (CC 10.1%, GC 63.0%, GG 29.6%) and the PCOS patients (CC 5.7%, GC 29.5%, GG 64.8%) (P < 0.001). The frequency of the polymorphic G allele was also no similar for the group with PCOS as for the control group with 79.5% and 58.4% respectively (P < 0.001). Both in PCOS patients and in control group, no statistically significant difference was determined between C/C, G/C and G/G, and blood cholesterol levels, triglyceride levels, high-density lipoprotein levels, low density lipoprotein levels, fasting blood sugar levels, insulin levels, HOMA values, CIMT measurements either on the right or left side, hs-CRP, f-testosterone, fibrinogen and 17 alpha-hydroxy-progesterone levels (P > 0.05). Gene polymorphism of IL-6 -174 G>C is a risk factor for PCOS in Turkish patients, but we found no relationship between the cardiovascular risk factors and IL-6 -174 G>C gene polymorphism in women with PCOS and healthy subjects. Our negative results in risk factors of CVD can probably be explained by the fact that metabolic parameters and endothelial systems of patients may not yet be affected in this short time of period.

Abstract
The aim of this randomised, double-blind study was to compare equipotent doses of plain ropivacaine and bupivacaine (19.5 mg and 13 mg respectively), both with fentanyl 20 microg, for spinal anaesthesia in lower abdominal surgery. After written informed consent had been obtained, 52 ASA I to II male patients scheduled for lower abdominal surgery were randomly assigned to receive intrathecal plain ropivacaine 19.5 mg with fentanyl 20 microg (group R, n =26) or plain bupivacaine 13 mg with fentanyl 20 microg (group B, n =26) in 3 ml. The level and duration of sensory block, intensity and duration of motor block, time to mobilise and patient satisfaction were recorded. All patients achieved sensory block to T10 or higher The level of sensory block was significantly higher in group B (T4 [T3 to T7] vs T7 [T4 to T9], P <0.05). There was no difference in the onset time of motor block. The duration of motor block (Bromage score >0) was shorter in group R (139+/-39 minutes vs group B 182+/-46 minutes, P <0.05). The duration and intensity of complete motor block (Bromage score=3) were also shorter in group R (90+/-25 minutes vs 130+/-40 minutes, P <0.05). We conclude that plain ropivacaine 19.5 mg plus fentanyl 20 microg is associated with a lower level of sensory block and a shorter duration of motor block when compared to bupivacaine 13 mg plus fentanyl 20 microg for spinal anaesthesia in lower abdominal surgery.

Abstract
OBJECTIVE The aim of our study was to demonstrate demographic characteristics, presence of inflammatory markers, distribution of angiotensin-converting enzyme (ACE), tumor necrosis factor (TNF), endothelial nitric oxide synthase (eNOS) genotypes and relations among these parameters in these patients and control subjects. RESEARCH DESIGN AND METHODS Study samples were collected from 50 patients with adrenal mass and 30 control groups. The eNOS, ACE, TNF-alpha, transforming growth factor (TGF)-beta genes polymorphisms, TNF-alpha, adiponectin levels were analysed in 50 unrelated Turkish patients with a diagnosis of adrenal incidentaloma (AI). RESULTS There was statistically significant difference between TNF-alpha levels of patient and controls (p=0.048). We have not detected the connection between TGF-beta, TNF-alpha, ACE, eNOS gene polymorphism with serum TNF-alpha and adiponectin levels. In this study, we demonstrated that there were significant differences for ACE genotypes in the patients when compared to the controls (p<0.05). The percentages of the ID, DD, II genotypes for ACE gene polymorphism in the patients group were 30.0, 13.0, 7.0%, respectively. CONCLUSIONS According to different cases of eNOS, TGF-beta, ACE, and TNF-alpha gene genotypes; no statistical significant difference was found between basal cortisol, ACTH, DHEAS, metanephrine, renin, aldosterone, normetanephrine, 17-hydroxyprogesterone, 1 mg low-dose dexamethasone suppression test-cortisol response and AI size. In this study, I/D genotype was determined to be statistically higher in ACE gene in patients with AI (p=0.014).

Abstract
INTRODUCTION Interleukins and cytokines play an important role in the pathogenesis of many cancers.We aimed to evaluate the interleukin (IL)-6 gene polymorphisms in patients with papillary thyroid carcinoma (PTC) and control subjects. MATERIAL AND METHODS In this study, 42 patients with PTC and 340 healthy controls were included. Peripheral blood samples were taken from control group and patients, and blood samples were preserved at -80 C in tubes containing Na-EDTA. RESULTS We also found a statistically significant difference between patients with PTC and the control group with respect to IL-6 genotype (p<0.05). IL-6 gene polymorphism in patients with PTC patients did not reveal statistically significant difference between the 2 groups (size of tumor >1 cm and <1 cm), multicentricity, RET-PTC types and capsule invasion (p>0.05).We also did not find a statistically significant difference between patients with PTC and the control group with respect to IL-6-gene allele frequency (p>0.05). DISCUSSION Our data suggest that the IL-6 G-174 C polymorphism could play a role in thyroid cancer risk, but there is no effective role as a prognostic factor.

Abstract
OBJECTIVE Apolipoprotein E (ApoE) genetic variation which is a major constituent of plasma lipoproteins causes diabetic nephropathy progress. Chronic kidney disease is associated with increased E2 allele and the decreased E4 allele risk. The aim of this study was to investigate the association between ApoE gene polymorphism in the development of diabetic nephropathy in Type 2 diabetes Turkish patients. RESEARCH DESIGN AND METHODS The objective of the study is to investigate the influence of ApoE gene polymorphism in the development of diabetic nephropathy in Turkish Type 2 diabetes. The ApoE genotypes were determined retrospectively in 46 patients with nephropathy and 56 without nephropathy and a control group of 35 healthy individuals. Genomic DNA was extracted from peripheral leukocytes of the subjects using the High Pure PCR Template Preparation Kit. For the detection of the presence of the three ApoE E alleles epsilon2, epsilon3, and epsilon4 (codon 112 and 158) were analyzed by the commercial LightCycler ApoE Mutation Detection Kit. RESULTS No differences in ApoE genotype or the allelic frequencies of epsilon2, epsilon3 or epsilon4 were found between the Type 2 diabetic patient group (with and without nephropathy) and a control group. CONCLUSIONS We conclude that the ApoE gene polymorphism is not associated with the development of diabetic nephropathy in Turkish Type 2 diabetic patients. Lack of association between ApoE gene polymorphism and Type 2 diabetic nephropathy might be due to ethnic differences.

Abstract
OBJECTIVE Interleukin-10 (IL-10) is a major anti-inflammatory cytokine that plays a crucial role in the regulation of the immune system. Chronic inflammation has been reported to be a risk factor for thyroid neoplasia. The propensity to mount an inflammatory response is modified by germ line variation in cytokine and other inflammation-related genes. We hypothesized that a proinflammatory genotype would be positively associated with thyroid cancer. We aimed to evaluate the relation between the genotypic and allelic frequencies of the IL-10(-1082 G/A), IL-10(-592 A/C), and IL-10(-819 C/T) polymorphisms, and their association with the risk of developing papillary thyroid cancer (PTC) in the Turkish population. RESEARCH DESIGN AND METHODS Forty-two patients with PTC and 113 healthy controls were included in this study. The diagnosis of PTC was confirmed by histopathologic examination after surgery. The evaluation of genotype for IL-10 gene polymorphism was performed using PCR-restriction fragment length polymorphism method. RESULTS Statistically significant difference IL-10(-1082 G/A) gene polymorphism was determined between 2 (PTC and control) groups. No difference was determined with respect to IL-10(-592 A/C) and IL-10(-819 C/T) gene polymorphisms, and IL-10(-1082 G/A), IL-10(-592 A/C), and IL-10(-819 C/T) allele frequencies of participating between the control group and the patients with PTC (p>0.05). CONCLUSIONS The polymorphism of IL-10(-1082 G/A) gene was significantly associated with the occurrence of PTC. Such studies will contribute significantly to our understanding of the biological role of IL-10(-1082 G/A) gene polymorphism in PTC development. In conclusion, IL-10(-1082 G/A) gene polymorphism may affect the survival of papillary thyroid carcinoma.

Abstract
OBJECTIVE In recent years, thyroid cancer has been at the forefront of molecular pathology as a result of the consequences of the Chernobyl disaster and the recognition of the role of RET/PTC rearrangements in papillary thyroid carcinomas (PTCs). Correlation of RET/PTC expression with clinical outcome is controversial. This study aims to identify the prevalence of RET/PTC oncogene expression in Turkey, and to investigate the correlation between RET/PTC oncogene expression and the known prognostic factors of PTC in 101 patients. METHODS The RET rearrangements were examined by means of reverse transcriptase-polymerase chain reaction analysis, with primers flanking the chimeric region. Statistical evaluation was performed by using Independent samples t-test, One-sample Chi-square test and Pearson Chi-square or Fisher's Exact Test. RESULTS RET/PTC was determined positive in 67(66.3%) of totally 101 patients (p<0.001). RET/PTC1 in 32(31.7%), RET/PTC3 in 21(20.8%), RET/PTC1+RET/PTC3 both in 10(9.9%) patients were found to be positive. There was RET/PTC2 positiveness in two patients, RET/PTC2,3 positiveness in one patient, and RET/PTC1,2,3 positiveness in one patient. No statistical difference was found between RET/PTC1 and RET/PTC3. None of genetico-clinical analyses showed any significant association between RET/PTC expression and the clinical and pathological features of the cancers. CONCLUSION While this prevalence of the RET/PTC is less than RET/PTC frequency seen after Chernobyl in Belarus, its prevalence in our region is also high (66.3%). As a result, no significant correlation was found in between prognosis and RET/PTC frequency.

Abstract
OBJECTIVE Interleukin-6 (IL-6) is a key pro-inflammatory and immune-modulatory cytokine of relevance for cardiovascular (CD) diseases. Cardiovascular risk factors that have been reported include oxidative stress markers [nitric oxide (NO), malondialdehyde (MDA), disulphite (SH)]. We aimed to evaluate the relation between the IL-6 G/C gene polymorphism and oxidative stress markers in polycystic ovary syndrome (PCOS) patients. DESIGN AND PATIENTS We studied 85 PCOS patients and 115 healthy controls. PCOS was defined by the Rotterdam PCOS consensus criteria. RESULTS The genotype IL-6 distribution did differ between the control group (CC 9.6%, GC 63.4%, GG 27.0%) and the PCOS patients (CC 4.7%, GC 29.4%, GG 65.9%) (p<0.001). The frequency of the polymorphic G allele was also not similar for the group with PCOS as for the control group with 80.6% and 58.7%, respectively (p<0.001). No statistically significant difference was determined for MDA and NO levels in PCOS patients and control group (p>0.05). Only SH levels were found to be high in favor of patient group (p<0.05). No statistically significant difference was determined between IL-6 G/C gene polymorphism and oxidative stress markers in PCOS patients and in the control group. CONCLUSION Gene polymorphism of IL-6 -174 G>C is a risk factor for PCOS in Turkish patients. IL-6 gene polymorphisms are not related to NO, MDA, and SH levels in PCOS. Our negative results in risks factors of CV disorders can probably be explained by the fact that metabolic parameters and endothelial systems of patients may not yet be affected in this short period of time.

Abstract
BACKGROUND Peroxisome proliferator-activated receptor gamma (PPAR gamma) has recently been shown to be associated with type 2 diabetes. We aim to investigate Turkish type 2 diabetic patients with/without diabetic nephropathy and healthy group and examined the contribution of the G/C exon 2 and T/C exon 6 of the PPAR gamma gene polymorphism to the development of diabetic nephropathy. METHODS The PPAR gamma genotypes were determined retrospectively in 43 patients with nephropathy and 48 without nephropathy and a control group of 50 healthy individuals. Genotyping of the G/C exon 2 and T/C exon 6 of the PPAR-gamma gene polymorphism for all individuals was performed by melting curve analysis of the generated amplicons after real-time online PCR. RESULTS This genotype (exon 2 and exon 6) distribution did not differ between control subjects and type 2 diabetic patients. The genotype frequencies and allele exon 2 were CC, 100%; GC, 0%; GG, 0% and C, 100%; G, 0% in diabetic patients with nephropathy versus CC, 97.9%; GC, 2.1%; GG, 0% and C 98.9%, G 1.1% in those without nephropathy. Genotype exon 6 frequencies in diabetic patients with nephropathy were (T/T) 0%, (T/C) 14%; (C/C) 86% versus (G/G) 0%; (G/C) 2.1%; (C/C) 97.9% in those without nephropathy. The PPAR gamma exon 2 and exon 6 genotype and allele frequencies were not different between diabetic patients with and without nephropathy. CONCLUSIONS PPAR gamma exon 2 and exon 6 gene polymorphism is not associated with the development of diabetic nephropathy in Turkish type 2 diabetic patients.

Abstract
BACKGROUND Poor glycaemic control, hypertension and duration of diabetes are risk factors for the development of diabetic nephropathy, but there may be genetic factors. Recently, a common C to T mutation at nucleotide position 677 of the MTHFR gene (MTHFR677C > T) has been reported to be correlated with hyperhomocysteinemia and the severity of coronary artery disease as macroangiopathy. We aim to investigate Turkish type 2 diabetic patients with/without diabetic nephropathy and healthy group and examine the contribution of the MTHFR gene polymorphism to the development of diabetic nephropathy. METHODS DNA was extracted from peripheral leukocytes of the subjects. Genotyping of the MTHFR C677T polymorphism for all individuals was performed by melting curve analysis of the generated amplicons after real-time online PCR. RESULTS This genotype distribution did not differ between control subjects and type 2 diabetic patients in which 6.8% were TT, 43.7% were CT and 49.5% were CC (chi2 = 0.201, p > 0.05). The frequency of the mutant T allele was 23.4% in diabetic patients with nephropathy versus 33.0% in those without nephropathy. The genotype frequencies were TT, 2.1%; CT, 46.6%; CC, 55.3% in diabetic patients with nephropathy versus TT, 10.7%; CT, 44.6%; CC, 44.6% in those without nephropathy. CONCLUSIONS The MTHFR genotype and allele frequencies were not different between diabetic patients with and without nephropathy (chi2 = 3, 386, p > 0.005; chi2 = 2.320, p > 0.005, respectively). Therefore, we conclude that the MTHFR gene polymorphism is not associated with the development of diabetic nephropathy in Turkish type 2 diabetic patients.

Abstract
BACKGROUND Turkey is an endemic area for thyroid diseases. The Aegean region is well documented for increased prevalence of thyroid disorders. In this study we investigated the demographic and clinical features of subacute thyroiditis (SAT) patients who had been diagnosed and treated in Ege University. METHODS The hospital files of patients admitted to the endocrinology clinic of Ege University between January 1987 and December 2001 were retrospectively evaluated. Patients who had been diagnosed as having any thyroid disorder were determined. RESULTS 176 fulfilled diagnostic criteria for SAT. The majority of patients with SAT were diagnosed as having subacute granulomatous thyroiditis (169/176) (134 females, 35 males, mean age 34.0+/-17.8 yr); 69% of the patients were between 30-50 yr of age. Thyroid pain was present in 97.1% of female patients, and in 100% of male patients. High fever was evident in 78 patients (46.2%). Mean erythrocyte sedimentation rate (ESR) was 43.42+/-39.68 mm/h. Anti-thyroglobulin antibody was positive in 20%, and anti-thyroid peroxydase antibody was positive in 4% of patients. Among patients who were treated with non-steroidal anti-inflammatory drugs (NSAD) 10 female patients (10.6%), and 3 male patients (12%) developed recurrence of the disease. Among patients who were treated with prednisolone 7 female patients (17.5%), and one male patient (10%) developed recurrence. There was no significant difference regarding the recurrence rates between patients who were treated with NSAD and patients who were treated with prednisolone. CONCLUSION With the exception of ESR, demographic, clinical, laboratory, and imaging findings and prognoses of our patients were comparable to the previous reports.

Abstract
OBJECTIVE Fas ligand (FasL) is an apoptotic agent and a member of tumor necrosis factor (TNF) family. FasL exists in cytotoxic T lymphocyte (CTL) and natural killer (NK) cells, and it is increased in tumor cell membrane. On the contrary, CTL and NK are bound to Fas on the surfaces of cell membrane; this triggers apoptosis in cytotoxic cells and leads to their death. This system plays an important role in eliminating viral infections and cancer cells. Malfunction of this system results in the development and spread of the malignancy. This study aims at evaluating the influence of Fas and FasL gene polymorphism in papillary thyroid cancer (PTC) in the Turkish population. RESEARCH DESIGN AND METHODS Forty-five patients with PTC and 100 healthy controls were included in this study. The diagnosis of PTC was confirmed by histopathologic examination after surgery. The evaluation of genotype for Fas 670 A/G and FasL 843 C/T gene polymorphism was performed using the PCR-restriction fragment length polymorphism (RFLP) method. RESULTS The evaluation of Fas/FasL genotype and gene allele frequency did not show statistically significant differences between the patient and control group (p>0.05). In addition, the univariate analysis did not reveal a statistically significant relationship between the size of the nodule and the Fas/FasL gene polymorphism in patients with PTC. CONCLUSIONS As in other types of malignancy, genetic factors in the pathogenesis of PTC may also show changes in different populations. Fas/FasL gene polymorphysms are possible that different mechanisms function in apoptosis balance in PTC development.

Abstract
AIM The purpose of this study was to determine whether spectral Doppler ultrasound (US) parameters, including resistive index (RI) and maximal systolic velocity (MSV), or vascular pattern can be used to distinguish malignant from benign thyroid nodules. MATERIALS AND METHODS We prospectively examined 169 thyroid nodules in 134 patients undergoing sonographically guided fine-needle aspiration biopsy (FNAB). Vascularity as determined by power Doppler US imaging was defined as absent, perinodular alone, or intranodular. For each nodule, the RI and MSV values were recorded as the average of the recordings obtained. Results of the FNAB and surgical pathological examination, if available, were used as a proof of final diagnosis to categorize all nodules as benign or malignant. RESULTS Seven nodules were excluded from study because of non-diagnostic FNAB results due to hypocellular or insufficient cytological material. Of the remaining nodules, nine were malignant (all confirmed at surgery) and 153 were benign. Of the 145 nodules with intranodular vascularity, nine (6.2%) were malignant and the remaining 136 (93.8%) were benign. The malignant nodules had a mean RI of 0.60 on intranodular and 0.58 on perinodular arteries. These values were not significantly higher than those associated with benign nodules (RI=0.57 and RI=0.56, respectively). Malignant nodules had a mean MSV of 20.4cm/s on intranodular and 35.3cm/s on perinodular arteries that were also not significantly different from those associated with benign nodules (p>0.05). CONCLUSION The results of this study indicate that Doppler US characteristics including vascular pattern, RI and MSV are not useful parameters for distinguishing malignant from benign thyroid nodules. Therefore, Doppler US characteristics including vascular pattern, RI and MSV values of thyroid nodules can not be used as a diagnostic method to determine which nodules should undergo FNAB.

Abstract
In this study, we investigated the effects of combining preprandial repaglinide to the insulin therapy for reducing the exogenous insulin requirements and serum HbA(1c) levels in type 2 diabetic patients whose blood glucose levels were previously regulated by multiple dose intensive insulin therapy. Fifty patients with type 2 diabetes who had been initially treated with oral antidiabetic agents without a satisfactory response were included in this study. After adequate glycemic control was achieved with intensive insulin therapy, the patients were divided into two subgroups. The first group continued with intensive insulin therapy. The second group received a combination of multiple insulin injections and oral repaglinide (1.5 mgr tid). The doses of insulin injections were gradually decreased accordingly in the second group. Both groups were followed-up for 3 months. Repaglinide was well tolerated and had no toxicity. A significant reduction regarding exogenous insulin requirements and serum HbA(1c) levels were demonstrated in patients taking preprandial repaglinide (p<0.01). Combining repaglinide to intensive insulin therapy could be a safe and effective alternative to intensive insulin therapy alone for the glycemic control and for reducing exogenous insulin requirements in type 2 diabetic patients.

Abstract
BACKGROUND In this prospective, clinical study we tested the hypothesis whether two different doses of spinal administered bupivacaine and accordingly, two different levels of spinal anaesthesia can affect the dose requirement of propofol during BIS guided sedation. METHODS Fifty women undergoing vaginal hysterectomy (high spinal group, HS) or transvaginal tape (TVT) procedure for urinary incontinence (low spinal group, LS) under spinal anaesthesia were enrolled to the study. In group HS, 17.5 mg and in group LS, 7.5 mg of hyperbaric bupivacaine were given intrathecally. After 15 min to obtain the appropriate level of spinal anaesthesia, propofol infusion was started at a rate of 100 microg kg(-1) min(-1) to reach a BIS level of less than 75 (onset time), and titrated to maintain the BIS value between 65 and 75. Propofol infusion was stopped 45 min after placing the spinal to measure the time to reach a BIS level of 90 (recovery time). RESULTS Median anaesthetic level was T3 (T1-4) in the HS group and T10 (T9-11) in the LS group. In both the HS and the LS groups, onset time was 226 (47) vs 273 (48) s (P=0.001), recovery time was 234 (47) vs 202 (56) s (P=0.03), total dose of propofol was 2.17 (0.43) vs 3.14 (0.56) mg kg(-1) (P<0.001), respectively. CONCLUSION A high spinal block obtained with hyperbaric bupivacaine 17.5 mg was associated with a faster onset, delayed recovery and lower doses of propofol sedation compared with a low spinal block with 7.5 mg of the same drug.
