Abstract
In this study, it was aimed to assess effects of subclinical hyperthyroidism (SH) on bone metabolism using osteoprotegerin (OPG), sclerostin, Dickkopf-1 (DKK1) and biochemical parameters. This cross-sectional prospective study included 40 patients with SH and 40 euthyroid controls. Serum OPG, sclerostin, DKK-1, type-1 procollagen, C-terminal polypeptide (CTx) and 24-hours urine N-terminal telopeptide (NTx) were measures using ELISA kit. Bone mineral density measurements were performed using dual energy X-ray absorptiometry (DEXA). Risk for 10-years hip and major fracture was estimated by Turkish version of FRAX. No significant difference was detected in age, gender, body mass index, smoking and menopause rates between SH and control groups. The risk for 10-years hip fracture and major osteoporotic fracture were estimated as 4.45% and 0.55% in SH group, respectively. The OPG levels were significantly lower in patients with SH than controls (P = 0.017). No significant difference was detected in other bone formation and degradation parameters. No significant correlation was detected between OPG level and risk for major osteoporotic fracture (P > 0.05); however, a negative correlation was detected between OPG level and risk for hip fracture (rho = 0.233; P = 0.038). Serum OPG is markedly affected in patients with SH. In addition, OPG seemed to be associated with osteoporotic fracture risk. Available data show that SH is significantly associated with risk for fracture; thus, it is important to assess risk for fracture in patients with SH.

Abstract
OBJECTIVE The aim of this study is to investigate the effect of telocytes on tubal motility in ectopic pregnancies. PATIENTS AND METHODS This study included patients with ectopic pregnancy (EP) (n=10) and control patients (n=10) (partial salpingectomy for contraception). Immunohistochemical staining for c-Kit, vimentin, CD34 and S100A was performed to quantify telocytes in the mucosa, muscular layer and serosa of fallopian tubes of control and EP group. Spontaneous and KCl- (80 mM) induced contraction and cumulative progesterone dose-relaxation (10-11-10-5 M) and cumulative oxytocin dose-contraction (10-10-10-4 M) responses were recorded. RESULTS The groups were comparable in terms of age, gravida, parity, delivery type and gestational week (p>0.05). The homogenous distribution of telocytes in the mucosa and muscular layers of the control group, changed to heterogeneous localization the EP group. Immunohistochemical staining with vimentin, S100A, c-Kit and CD34, revealed increased telocyte counts in the muscular layer and serosa of the tubal tissues of EP. The frequency of the spontaneous contractions was higher in the control group (p<0.001); contrarily, the amplitude of the contractions was higher in ectopic pregnancies (p<0.001). Although the cumulative oxytocin dose-contraction curves were similar at all concentrations (p>0.05), the cumulative progesterone dose-relaxation curves exhibited higher relaxation response in the EP group at all concentrations (p<0.001). CONCLUSIONS Increased telocyte count in the fallopian tube may decrease tubal motility and may affect the transfer of the blastocyst to the uterus and possibly contribute to the pathogenesis of EP.

Abstract
BACKGROUND/AIM Inflammatory bowel disease (IBD) mainly encompass two entities called ulcerative colitis (UC) and Crohn's disease (CD), both of which are chronic, progressive and, inflammatory conditions of the gastrointestinal tract. Various indicators and non-invasive markers have been sought and used in IBD patients to help assessing disease activity and treatment effectiveness, although none of them are proven to yield definite results in full correlation with the clinical, endoscopic, and histopathological examinations. The aim of the current study was to investigate the relationship of serum neutrophil gelatinase-associated lipocalin (NGAL), asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA) levels with disease type and activity and to assess their potential use in establishing diagnosis and activity status of IBD, namely UC and CD. MATERIALS AND METHODS A total of 111 IBD patients with determined active and inactive disease periods and 70 matched controls were recruited. Serum NGAL levels of the patients and the control group were measured using commercially available ELISA kits. ADMA and SMDA levels were accomplished by high performance liquid chromatography. RESULTS The IBD group had significantly higher serum levels of NGAL (p= 0.001), ADMA (p= 0.0001), and SDMA (p= 0.0001) in comparison to the control group. Likewise, serum NGAL, ADMA, and SDMA levels were significantly higher in the active IBD group compared to the inactive IBD group (p= 0.0001). Active UC and active CD patients similarly had significantly higher levels of serum NGAL, ADMA, and SDMA than the respective levels in inactive UK and inactive CD patients (p= 0.0001). CONCLUSION Serum NGAL, ADMA and SMDA levels are increased in patients with IBD and serum NGAL, ADMA and SMDA concentrations are significantly higher in active IBD patients than inactive IBD patients. Our results suggest these biomarkers may serve in estimating IBD activity and severity.

Abstract
Introduction Traumatic experiences has a key role on the mental health of individuals. Turkish Armed Forces has been involved in various combat in and out of the country over the years. Individuals who are able to find meaning after a negative life events are better overcome their issues and return to their positive functioning. Unhealthy attachment styles has been observed more in clinical samples than healthy attachment styles. Objectives The aim of this study was to investigate the predictive role of attachment styles and meaning in life on psychiatric symptoms among wife of military personel who lost their lifes. Methods 74 women who lost their husband in combat to the study. Their age was between 21 and 74, with the mean of 46.93. 60 (75.9%) participants had a child when they lost their husband. 63 (79.7%) of them hasn’t been married again. Brief Symptom Inventory, Meaning in Life Scale and Relationship Scales Questtionnare were used to collect the data. Five different regression analysis was conducted. Results Finding meaning in life, dismissing and preoccupied attachment sytles predicted depression (R2= 51.8%). Finding meaning in life and fearful attachment styles predicted anxiety (R2= 46.2%). Finding meaning in life and fearful attachment styles predicted negative identity (R2= 51.1%). Finding meaning in life and dismissing attachment styles predicted hostility (R2= 50.4%) and somatization (R2= 57%). Conclusions Meaning in life has a protective role in the development of any psychopathologies whereas insecure attachment styles are risk factor. Disclosure No significant relationships.

Abstract
Introduction As in many areas of life, the covid-19 epidemic has had a great impact on psychological counselor training. Although studies and practices on online counseling are increasing every day in the world, there has not been a psychological counseling method preferred by experts in Turkey, which comes from community culture and, where physical contact is important, until the pandemic. Objectives The examination of the opinions of the students studying in the last year of the psychological counseling and guidance undergraduate program during the pandemic regarding online counseling, where they perform their first psychological counseling experience. Methods The study was conducted with 10 counseling students, 9 women and 1 Man. The age range of the students is 22-24 and the average age is 20.6. The students’ opinions are taken with open-ended questions such as “Can you share your views on online counseling before online counseling?“ The reflection letter that the students responded to was subjected to content analysis. Results The findings of the study show that there are four themes: Emotions before the counseling process, Thoughts before the counseling process, Therapeutic relationship, Online counseling in professional life. For example; in online counseling, negative emotions such as anxiety, excitement, fear, anxiety, stress, anxiety, as well as feeling comfortable and safe are among the positive feelings they experience in their therapeutic relationships. Conclusions As a result, although students have a positive view of online counseling, they mainly prefer to do it face-to-face. The findings were discussed taking into account Turkish culture.

Abstract
BACKGROUND/AIMS Celiac disease is an autoimmune, familial disease that results in susceptibility to gluten in cereal and cereal products in genetically susceptible individuals. The aim of the present study was to investigate the presence of HLA-DQ2/DQ8 in patients with celiac disease, their first-degree relatives, and healthy community. MATERIALS AND METHODS HLA-DQ2/DQ8 analysis was performed in adult patients with celiac disease >18 years old (94 patients), their first-degree relatives (89 people), and healthy group (102 individuals). Anemia, osteoporosis, and diarrhea were interrogated in the celiac patient group and also anti-tissue transglutaminase, anti-endomysium, and anti-gliadin antibodies were recorded. RESULTS There was a significant relationship between HLA-DQ2/DQ8 presence in all groups, and the distribution of HLA-DQ2/DQ8 in all groups was different (p=0.000). No statistically significant correlation was found between the HLA tissue groups and diarrhea (p=0.087), osteoporosis (p=0.215), anemia (p=1.000), tissue transglutaminase antibodies (p=0.295), anti-gliadin antibodies (p=0.104), and anti-endomysium antibodies (p=0.243) in the celiac patient group. CONCLUSION HLA-DQ2/DQ8 can be used to diagnose celiac disease particularly when the tests are useless and to screen first-degree relatives.

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
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
Pituitary apoplexy (PA) is a life-threatening clinical syndrome. Dopamine receptor agonists are the drugs of choice in the treatment of prolactinomas. The use of cabergoline is reported to cause an increased risk of PA, particularly in macroprolactinomas of cystic nature. In this report, we present a patient with a cystic macroprolactinoma who developed PA on the 16th week of cabergoline treatment.

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
AIM To evaluate the impact of postmenopausal osteoporosis on thiol/disulfide homeostasis. MATERIALS AND METHODS A total of 75 participants were divided into two groups: Group 1 (n = 40) was composed of healthy postmenopausal women, and group 2 (n = 35) was composed of women with postmenopausal osteoporosis. Clinical findings and thiol/disulfide homeostasis were compared between the two groups. RESULTS The disulfide/native thiol ratio was 8.6% ± 3.6 in group 1 and 12.7% ± 8.4 in group 2 (p = 0.04). The disulfide/native thiol percent ratio was significantly higher in group 2 after adjustment for the years since menopause and age (p < 0.05). The native thiol/total thiol percent ratio was 85.6% ± 4.8 in group 1 and 73.8% ± 24.9 in group 2 (p = 0.01). The native thiol/total thiol percent ratio was significantly lower in group 2 after adjustment for the years since menopause and age (p < 0.05). CONCLUSION Thiol/disulfide homeostasis shifted to the disulfide side independent of age and years since menopause in postmenopausal osteoporosis.

Abstract
OBJECTIVE Research data demonstrating nutritional habits of functional dyspepsia (FD) patients are very limited. This is the first study to evaluate nutritional habits in FD subgroups according to Rome III criteria. Our aim was to evaluate nutritional habits of FD patients and determine the food items that may provoke a dyspepsia symptom. METHODS A total of 168 adults with FD and 135 healthy control subjects participated in the study. FD subjects were divided into epigastric pain syndrome (EP-FD), postprandial distress syndrome (PS-FD), mixed (MX-FD) subgroups according to Rome Criteria III. Subjects completed a questionnaire that included a short-form food frequency questionnaire. Furthermore, subjects were asked to list the food items that were causing a dyspepsia symptom. RESULTS Functional dyspepsia subjects had a slightly higher BMI (26.1 ± 4.97 kg/m(2)) than control subjects (24.6 ± 4.08 kg/m(2)). The most common symptom triggering foods among all the FD groups were fried and fatty foods (27.1%), hot spices (26.4%), and carbonated drinks (21.8%). In FD subgroups, carbonated drinks were more likely to cause a symptom in PS-FD group (37.3%) than MX-FD (25.7%) and EP-FD (22.1%) groups. There was no difference in frequency of main meals and snacks among any of the groups. CONCLUSION Fatty and spicy foods and carbonated drinks were the most common symptom triggering food items in FD group. In subgroups, carbonated drinks and legumes were more likely to cause a symptom in PS-FD. Removing these food items during the course of treatment might help alleviate the symptoms.

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
BACKGROUND/AIMS Chronic gastritis progression is a multistep process of atrophy, intestinal metaplasia (IM), and dysplasia, which may lead to invasive carcinoma. In this study, we identified an association of colonic polyps with gastric IM in patients undergoing colonoscopy. MATERIALS AND METHODS This retrospective case-control, cross-sectional study was conducted in a tertiary-care institution in Turkey. Pathology and endoscopy reports were reviewed. The study group comprised 400 patients with colonic adenomatous polyps, and the control group comprised 360 patients without colonic adenomatous polyps on colonoscopy. RESULTS The risk of gastric IM was 1.42-fold higher in the study group (p<0.05). The risk of IM in patients aged ≥50 years with colonic polyps was 3.35-fold higher than in those aged <50 years (p<0.05). The risk of Helicobacter pylori infection in the study group was 1.07-folder higher than that in the control group (p<0.05). H. pylori infection prevalence was higher only in patients with high-grade colonic polyp dysplasia (p<0.05). There were no statistically significant differences in the proportion of incomplete IM between the groups (p<0.05). CONCLUSION This study observed increased rates of gastric IM with colonic polyps. An increased risk of gastric IM was associated with higher grades of polyp dysplasia.

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
BACKGROUND/AIMS To provide a new mathematical formula to predict liver fibrosis in patients with chronic viral hepatitis. MATERIALS AND METHODS Patients with chronic hepatitis B and C who underwent liver biopsy at different centers were included in this study. Chronic hepatitis B was defined as immunopositivity for the hepatitis B surface antigen for at least 6 months, and chronic hepatitis C was defined as positivity for HCV RNA for at least 3 months. The histological features were evaluated by the histological activity index and fibrosis. RESULTS In total, 1299 patients were included in the study. The distribution and the mean of the parameters of the patients were as follows: 1009 patients with chronic hepatitis B with a mean age of 45±13/years [emale/male (F/M)=47.5/52.5%] and 290 patients with hepatitis C with a mean age of 52±10.3/years [F/M=61/39%]. When the cut-off value of the REAL TEST formula"[(age x pT x AST)/(PLT/1000)]/100" in patients with hepatitis B was determined to be ≥1.37, it was found that it could predict fibrosis with 79% specificity, 78% sensitivity, 85% negative predictive value (NPV), and 70% positive predictive value (PPV) (area under the curve (AUC)=0.852, 95% CI:0.82-0.87). When the cut-off value of the REAL TEST formula in patients with hepatitis C was determined to be ≥1.99, it was found that it could predict significant fibrosis with 87% specificity, 90% sensitivity, 94.4% NPV, and 79.4% PPV (AUC:0.95, 95% CI:0.93-0.98). CONCLUSION The REAL TEST formula results correlated with the pathological findings and may be a useful method for the evaluation of patients with chronic hepatitis B and C.

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 The metabolic syndrome (MetS) is a common multicomponent condition including abdominal obesity, dyslipidemia, hypertension and hyperglycemia. The aim of this study was to investigate the associations of Rho GTPase and Rho-kinase (ROCK) gene polymorphisms and expressions with MetS in a Turkish population. PATIENTS AND METHODS A total of 141 obese MetS patients and 163 healthy controls with similar age and sex were included to this study. Polymorphisms were analyzed in genomic DNA using a BioMark 96.96 dynamic array system. mRNA from blood samples was extracted, and real-time polymerase chain reaction was performed for gene expressions. RESULTS We observed that genotype (CC, 18.1%; CA, 13.4%, and AA, 68.5%) and allele (C, 24.8%; A, 75.2%) frequencies for the rs35996865 polymorphism of the ROCK1 gene in patients were markedly different from controls (CC, 84.2%; CA, 2.9%, and AA, 12.9%; C, 85.6%; A, 14.4%, p < 0.0001). In the rs2230774 (Thr431Asn) polymorphism of the ROCK2 gene, there were increases in the CC genotype (16.5%) and C allele frequencies (20.4%) in MetS patients when compared with the control group (CC, 6.0%, p = 0.0009, and C, 6.7%, p < 0.0001). However, no associations with the other 18 polymorphisms studied were found. Although there were an increase in peripheral blood mRNA RhoH expressions, marked decreases in RhoC, RhoBTB1, RhoV, Rnd1, and CDC42 gene expressions were noted in MetS patients. CONCLUSIONS This is the first study to provide evidence that ROCK gene polymorphisms and gene expressions of the Rho GTPase proteins may modify individual susceptibility to MetS in the Turkish population.

Abstract
OBJECTIVE We aimed to investigate the effect of fish oil on the hepatic injury and cell cycle phases as well as cellular proliferation- regeneration in a rat model of acute hepatic injury induced by carbon tetrachloride. BACKGROUND Compensatory cell proliferation and tissue regeneration occurs as an endogenous response following chemical damage to the liver and enable animals to over come the injury. Data related to effect of fish oil on liver injury induced by chemical hepatotoxicants are controversial. METHOD 60 male Wistar-albino rats were fed either with a diet supplemented with 20% fish oil or standard rat feed for 2 weeks. After an overnight fast, rats in each group were administered either 1 ml/kg carbon tetrachloride or saline intraperitoneally. RESULTS Fish oil enriched diet significantly enhanced the carbon tetrachloride - associated necroinflammatory damage, ballooning degeneration and the elevation of serum transaminases induced by carbon tetrachloride. Furthermore fish oil diet prevented cell proliferation, increased the proportion of cells in the G0/G1phase concomitant with a decrease in the proportion of cells in the S phase cells. CONCLUSION Fish oil diet exacerbates the hepatic injury and prevents cell proliferation-regeneration in normal and injured liver cells. Suppression of tissue regeneration by fish oil may lead to progression of the hepatic injury (Tab. 3, Fig. 4, Ref. 31).

Abstract
Increasing non-ecological land use necessitates more efficient using and utilization of land by man. Therefore, in recent years studies on sustainable land use have gained momentum. In this study, temporal change in land use, mainly between years 1940 and 2010, in Asi river delta on Southern Turkey was covered. To this end, in addition to literature, topographical maps and satellite images from year 1940 and after were used. Also, data were collected through field studies and interviews. Collected data were evaluated from geographical viewpoint using Geographical information system (GIS) and Remote sensing (RS) methods. Unplanned settlement in delta has reached levels high enough to threaten agricultural fields. Especially, greattendencyshown by Samandag city and the villages around it towards expanding into delta is an indicatorof this threat In additon, uncontrolled sand mining and touristic facilities on the coastline are also indicators of wrong land use. In future, direction of settlement to slopes around the delta rather than lowlands will be a much more ecological approach.

Abstract
Carotid blowout syndrome (CBS) is an emergency complication in patients undergoing treatment for head and neck cancers. The classical management of CBS is the ligation of the common carotid artery, because suturing is not be possible due to infection and necrosis of the field. In this case report, we present a patient with CBS, in whom we applied a self-expandable polytetrafluoroethylene (PTFE) stent and observed no morbidity. Endovascular stent is a life-saving technique with minimum morbidity that preserves blood flow to the brain. We believe that this method is preferable to ligation of the artery in CBS.

Abstract
Ganglioneuromas (GNs) are well-differentiated, slow-growing, benign tumors that are quite rare and usually found in the posterior mediastinum and retroperitoneum. They are composed of ganglion and Schwann cells and their origin remains in dispute. GNs have been reported as intraosseous lesions, such as in temporal and orbital bones. There are rare reports of intracranial lesions, mostly in the pituitary fossa. Most GN patients are children and are clinically asymptomatic. Diagnosis of GN requires histopathologic evaluation since no specific clinical or radiologic diagnostic features have been identified. We report the case of a 35-year-old man with recurrent sinusitis whose radiologic workup revealed a lytic right sphenoid wing lesion with microcalcifications. He underwent gross-total resection of the lesion and the pathologic findings were diagnostic of ganglioneuroma. To the best of our knowledge, this is the first reported case of sphenoid wing GN. The nature and origin of this tumor are discussed, and the GN literature is reviewed.

Abstract
OBJECTIVE This study aimed to elucidate the potential inner-ear effects of fotemustine, a chemotherapeutic agent which crosses the blood-brain barrier and is used in the treatment of primary and metastatic brain tumours and metastatic melanoma. METHODS This study utilised distortion product otoacoustic emissions and transmission electron microscopy in order to conduct electrophysiological and morphological assessments, using a rat experimental model. Twelve ears of six male rats were examined two months following intraperitoneal slow infusion of fotemustine (100 mg/m2 or 7.4 mg/kg). Pre- and post-treatment measurements were compared. Finally, electron microscopy was performed on three rat temporal bones. RESULTS After infusion of fotemustine, distortion product otoacoustic emissions revealed a significant reduction in signal-to-noise ratios only at 3600 Hz (from 11.95 +/- 7.52 to -0.26 +/- 9.45 dB) and at 3961 Hz (from 18.09 +/- 7.49 to 6.74 +/- 12.11 dB) (referenced to 2f1 - f2). Transmission electron microscopy of the temporal bone revealed ultrastructural changes in the outer hair cells, stria vascularis and cochlear ganglion at the cochlear basal turn. The ganglion cell perikarya were unaffected. CONCLUSIONS Fotemustine was administered via intraperitoneal slow infusion in a rat experimental model. Twelve ears of six survivors, from 10 rats, were evaluated at the second month. Fotemustine was determined to have a potential for ototoxicity at 3600 and 3961 Hz. Three randomly chosen rats underwent electron microscopy for morphological analysis. Morphological effects in the cochlear basal turn were observed. Oedematous intracytoplasmic spaces and perivascular areas of the stria vascularis, as well as distorted chromatin content, were detected, thereby suggesting potential ototoxic effects for this agent. Further experimental and clinical studies are required in order to determine whether the effect seen in this pilot study is reversible, and to analyse effects in humans.

Abstract
The effects of two doses (50 and 100 mg/kg body wt given orally for 14 days) of an ethanol-water (80%-20%) extract of Urtica dioica L. and butylated hydroxyanisole (BHA) were investigated, for phase I and phase II enzymes, antioxidant enzymes, lactate dehydrogenase, lipid peroxidation and sulfhydryl groups in the liver of Swiss albino mice (8-9 weeks old). A modulatory effect of two doses and BHA was also observed for the activities of glutathione S-transferase, DT-diaphorase, superoxide dismutase and catalase in the kidney, lung and forestomach, as compared with the control group. The activities of cytochrome b5 (cyt b5), NADH-cytochrome b5 reductase (cyt b5 R), glutathione S-transferase (GST), DT-diaphorase (DTD), glutathione peroxidase (GPx), glutathione reductase (GR), superoxide dismutase (SOD) and catalase (CAT) showed a significant increase in the liver at both dose levels of extract. Both extract-treated showed significantly lower activity of cytochrome P450 (cyt P450), lactate dehydrogenase (LDH), NADPH-cytochrome P450 reductase (cyt P450 R), total sulfhydryl groups (T-SH), nonprotein sulfhydryl groups (NP-SH) and protein-bound sulfhydryl groups (PB-SH). BHA-treated Swiss albino mice showed a notable increase in levels of cyt b5, DTD, T-SH, PB-SH, GPx, GR, and SOD in the liver while, LDH, cyt P450, cyt P450 R, Cyt b5 R, GST, NP-SH, and CAT levels were reduced significantly as compared to control values. The extract was effective in inducing GST, DTD, SOD and CAT activity in the forestomach and SOD and CAT activity in the lung at both dose levels. BHA-treated Swiss albino mice induced DTD, GST and all antioxidative parameters in the kidney, lung and forestomach.

Abstract
OBJECTIVE To identify features of major salivary gland cancers that are prognostic for disease-free survival. STUDY DESIGN A retrospective study of 78 patients with major salivary gland cancer (64 parotid and 14 submandibular gland) who underwent surgery for definitive treatment from 1976 to 1996. A select group of patients also received adjuvant radiation (56%) and/or chemotherapy (13%). METHOD Clinical and pathological risk factors were obtained from patients' charts and pathology reports. Age, gender, tumor site, T-stage, facial paralysis, histologic neck involvement, perineural invasion, and cancer grade were analyzed with respect to disease-free survival. The role of adjuvant treatment in terms of clinical outcome was also investigated. RESULTS In our series, the 5-year disease-free survival was 65%. Examining clinical and histologic features one at a time, we found poorer prognosis was associated with submandibular tumors compared with parotid (P =.02), higher T-stage (P =.001), positive cervical nodes (P <.001), perineural invasion (P =.002), and high-grade or adenoid cystic tumors (P =.002). A multivariable analysis indicated that positive lymph nodes (P =.07) and perineural invasion (P =.03) were important histologic predictors of shorter disease-free survival. Receipt of both adjuvant radiation and cisplatin-based chemotherapy (P =.05) was an independent predictor of longer disease-free survival. CONCLUSION Our study indicated that the presence of positive lymph nodes and perineural invasion is important independent predictors of disease-free survival. Our limited data also suggest that adjuvant chemotherapy and radiation therapy may improve disease-free survival.

Abstract
PURPOSE Management of the carotid artery involved with metastatic squamous cell carcinoma continues to be a topic of much discussion. Early reports, for the most part, focused on the sequel of ligation and the development of various tests to predict patient tolerance for the procedure. More recent alternatives have described resection reconstruction in multistage procedures. By using immediate reconstruction with autogenous arterial grafting, carotid artery resection can be accomplished in patients with radiation failure in a single stage. This technique can be used without the addition of myocutaneous flaps, controlled fistulas, or intracranial surgery advocated for usage with alternative techniques. PATIENTS AND METHODS Immediate reconstruction after resection of the carotid artery with superficial femoral arterial graft is described. RESULTS In a series of 18 high-risk patients with radiation failure, the artery was successfully resected and reconstructed in 1 stage without any neurologic or vascular complications. The technique has been associated with prolonged survival in selected patients. CONCLUSION Carotid artery resection and immediate reconstruction can be performed in high-risk radiation failure patients with acceptable complications, and is associated with prolonged survival in selected cases.

Abstract
PURPOSE We designed a computerized tomography (CT)-based silastic implant preparation method that enabled custom fit to the individual size of the patient's larynx for medialization laryngoplasty. MATERIALS AND METHODS Three women with unilateral vocal cord paralysis underwent type I thyroplasty operation. The individual size of the patient's larynx was determined by preoperative measurements on CT scan and the implant was prepared accordingly. The implant was then inserted through a rectangular window at the level of vocal cords which had been outlined according to CT findings. RESULTS Three patients, who were age 41, 25, and 37 years, underwent medialization laryngoplasty by this technique. They were followed up for 37, 16, and 4 months, respectively. There was not any rejection reaction, and satisfactory functional results with 10, 7, and 9 seconds of phonation duration have been achieved, respectively. CONCLUSION In this technique, the desired medialization of the paralyzed vocal cord was accomplished by the first insertion of the implant. Thus, the duration of the operation and the vocal cord edema aroused by manipulation of the inner perichondrium and internal laryngeal structures were reduced.

Abstract
PURPOSE Define radiological and histological features in which patients with head and neck cancer would benefit from a carotid artery resection. Resection of the carotid artery has been advocated for local control of advanced squamous cell carcinoma of the head and neck. To provide appropriate preoperative counseling and optimize the utilization of resources, the criteria for patient selection has to be defined. METHODS Thirty-four patients underwent carotid artery resection based on the clinical impression of tumor fixation. Eighteen and 28 patients were evaluated using computed tomography (CT) and histological analysis, respectively. The distance between the tumor cells and external elastic lamina was measured. CT scans were examined to determine the circumference of tumor attachment around the carotid artery. RESULTS Clinical assessment predicted tumor within 1.8 mm of the carotid artery in 68% of cases. The overall survival for patients with tumor greater than 1.8 mm (N = 9) was better than that of patients with less (N = 19) than 1.8 mm (33.3% vs. 5.3%; median 24 versus 9 mo, P = .0899). Three of six patients (50%) with less than 180 degrees circumference tumor attachment had tumor within 1.8 mm from the external elastic lamina. Eight of twelve patients (67%) with tumors encompassing more than 180 degrees of the artery wall had tumor within 1.8 mm from the external elastic lamina. The overall survival rates for patients with tumor attachment greater and less than 180 degrees were 8.3% and 33%, respectively. DISCUSSION Tumor invasion into the carotid artery was the strongest predictor of outcome. Clinical assessment was as predictive as CT for tumor invasion. If tumor involvement of the carotid artery is less than 180 degrees, peeling the tumor is an alternative to carotid artery resection.

Abstract
PURPOSE Cervical lymph node status is a widely accepted important prognostic parameter in laryngeal carcinoma. PATIENTS AND METHODS In this study, we retrospectively reviewed neck specimens of 46 laryngeal carcinoma patients operated in our clinic. Presence of neck metastasis and pattern of reactivity in nonmetastatic nodes was correlated with recurrence and survival during a follow-up period of at least 2 years. RESULTS Fourteen of the patients had at least one metastatic node and survival was 64%; 32 of the patients had reactional nodes only and the survival was 81%. Pattern of lymph node reactivity was evaluated as stimulated in type I (lymphocyte predominance) and type II (germinal center predominance); as unstimulated in type III (histiocytosis and/or normal) and type IV (lymphocyte depletion). Thirty two neck [-] patients had reactional nodes--16 of them were classified as stimulated and 16 of them as unstimulated; the 2-year survivals were 94% and 68%, respectively. In the 14 patients with cervical metastasis (classified according to nonmetastatic reactional nodes) 9 were stimulated and 5 were unstimulated with 2-year survivals of 100% and 0%, respectively. CONCLUSION Stimulated lymphatic pattern reflects a better prognosis, especially in N+ neck laryngeal cancer patients.

Abstract
Endoscopic sinus surgery (ESS) is a method used with success in the treatment of chronic inflammatory paranasal sinus diseases. Between February 1991 and June 1995 the Messerklinger technique for ESS was used in 415 patients who had been pre-operatively evaluated in detail according to the staging system used in our clinic. Average post-operative follow-up was 23 months. Our general success rate was found to be 86.3% upon evaluating the subjective improvements in the patients' symptoms in the post-operative period. The major and minor complication rates in our series were 0.24 and 20.24%, respectively.
