Abstract
BACKGROUND The aim of this study was to investigate relationships between early atherosclerosis and inflammatory bowel disease (IBD) using laboratory, functional, and morphological markers of atherosclerosis. MATERIAL AND METHODS In the present prospective single-center study, 96 patients with IBD (58 patients with ulcerative colitis and 36 patients with Crohn's disease) and 65 healthy control subjects were included. The demographic data of each patient and control subject were recorded. The patients with IBD and healthy controls were compared in terms of the carotid intima-media thickness (CIMT), the values of flow-mediated dilatation (FMD) and nitroglycerine-mediated dilatation (NMD), and the levels of von Willebrand factor antigen (VWF-Ag), D-dimer, and lipoprotein (a). RESULTS There were no significant differences between the IBD patients and controls in terms of age, sex, BMI, systolic and diastolic BPs, serum levels of total cholesterol, low-density lipoprotein, or triglycerides. IBD patients had significantly higher levels of VWF-Ag (156.6±58.9 vs. 104.2±43.3, P<0.001) and D-dimer (337.2±710.8 vs. 175.9±110.9, P<0.001) as compared to the controls. No significant differences were determined between the 2 groups in terms of FMD and NMD values. Although statistically not significant, the CIMT values were higher in the IBD patients than in the controls (0.517±0.141 mm vs. 0.467±0.099 mm, P=0.073). In the correlation analysis, the CIMT was found to be correlated negatively with FMD and positively with high sensitive C-reactive protein, VWF-Ag, and D-dimer. CONCLUSIONS These findings suggest that VWF-Ag and D-dimer can be beneficial early atherosclerosis markers in IBD patients.

Abstract
BACKGROUND/AIM Irritable bowel syndrome (IBS) is a gastrointestinal condition characterized by chronic abdominal pain, discomfort, bloating, and alteration of bowel habits in the absence of any organic cause. This trial investigated the presence of microscopic colitis (MC) and associated factors related to MC in patients diagnosed with IBS. MATERIALS AND METHODS The study group (group I) consisted of 91 consecutive patients diagnosed with IBS based on the Rome III Criteria for whom colonoscopic examination was requested. The control group (group II) had 41 patients diagnosed with IBS considered as eligible for colonoscopic investigation due to specific conditions, and for whom colonoscopic examination was recommended for screening purposes due to a familial history of colon cancer. Clinical data, endoscopic findings, and the effects of the therapy were evaluated. RESULTS In the diarrhea-predominant IBS group, nine patients (9.89%) were diagnosed with microscopic colitis, seven with lymphocytic colitis (7.69%), and two with collagenous colitis (CC) (2.19%). None of the patients in group II were found to have MC (P = 0.007). There were no diagnoses of MC in the constipation-predominant and mixed type IBS groups. CONCLUSION Clinicians should keep MC in mind for patients presenting with diarrhea-predominant IBS symptoms.

Abstract
BACKGROUND/AIMS To evaluate the effectiveness of tenofovir in patients with chronic hepatitis B infection in a real life setting. MATERIALS AND METHODS We performed a retrospective analysis of data from 164 patients with chronic hepatitis B who were treated with Tenofovir. Eighty-six patients (52.4%) were naïve. Seventy-seven (46.9%) patients were previously treated with anti-viral drugs, including standard interferon (n=4), pegylated (PEG) interferon (n=14), standard interferon together with lamivudine (n=13), lamivudine alone (n=41), adefovir (n=2), lamivudine together with adefovir (n=1), and entecavir (n=2). Six patients (3.7%) had liver cirrhosis before treatment of tenofovir. RESULTS The patients who have hepatitis B viral DNA>104 copy/mL with chronic hepatitis B infection were included in the treatment of Tenofovir. Average follow up time was 30.31±14.33 months. HBV DNA negativity and alanine aminotransferase (ALT) normalization were 86.5% and 71.3%, respectively, at the last visit. Hepatitis B e-Antigen (HBeAg) seroconversion occurred in 11 (19.6%) out of 164 patients. During the follow-up period, 4 (2.4%) patients developed liver cirrhosis and in 5 (3%) patients hepatocellular carcinoma (HCC) occurred out of 164 patients. HBsAg seroconversion occurred in one patient (0.6%). CONCLUSION Tenofovir can be used safely and successfully in those patients that were naive, experienced with immune modulators and/or antivirals, HBeAg-positive, and HBeAg-negative patients.

Abstract
Colorectal cancer (CRC) is the third most common cause of cancer-related death in Europe. The aim of the present study was to elucidate the efficiency of the neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR), and the mean platelet volume (MPV) as tools for the preoperative diagnosis of CRC and their usefulness in the follow-up of CRC. A total of 144 CRC patients, as diagnosed by colonoscopy, and 143 age-matched and sex-matched healthy participants were included in the study. Medical records were used to compare preoperative and postoperative data including hemoglobin levels, platelet counts, MPV, NLR, and PLR. NLR, PLR, and MPV were significantly higher in CRC patients preoperatively, compared with healthy participants. Receiver-operating characteristic curve analysis suggested 2.02 as the cutoff value for NLR [area under the curve (AUC): 0.921, sensitivity: 86%, specificity: 84%], 135 as the cutoff value for PLR, (AUC: 0.853, sensitivity: 70%, specificity: 90%) and 8.25 fl as the cutoff value for MPV (AUC: 0.717, sensitivity: 54%, specificity: 76%). Subgroup analysis showed that NLR, PLR, and MPV levels were also significantly higher in nonanemic CRC patients compared with the control group, which is of great theoretical and clinical value for the early detection of CRC. Surgical tumor resection resulted in a significant decrease in NLR, PLR, and MPV. Our results suggest that NLR, PLR, and MPV may be used as easily available additional biomarkers for CRC in screening the general population, as well as in postoperative follow-up.

Abstract
BACKGROUND/AIM Even though polyethylene glycol-electrolyte lavage (PEG-EL)-based regimes have become the gold standard in recent years, to finish drinking 4 L of PEG-EL solution can be difficult. The quality of sennoside-based bowel-cleansing regimes used in Turkey has been known for some time. Therefore, we aimed to investigate the efficacy of both bowel-cleansing regimes. MATERIALS AND METHODS Patients over 18 years old undergoing elective colonoscopic procedures between January and March 2011 were included in the study. The patients were divided into 2 groups; in Group 1, 91 patients were given sennoside a + b calcium 500 mg/250 mL (X-M solution, Yenişehir Laboratuarı, Ankara, Turkey), and in Group 2, 94 patients were given 4 L of PEG-EL (Golytely, Boston, MA, USA). RESULTS The mean age of the patients and the male distribution were similar in the 2 groups. Both inadequate bowel cleansing and the best cleansed bowels were seen in Group 1. The number of inadequate colonoscopies declined when using a whole bowel-cleansing regime from 24.5% to 19.3% in Group 2, but it did not decline in Group 1. CONCLUSION The best bowel cleansing can be achieved with sennoside-based regimes, whereas a greater proportion of adequate results via colonoscopy were reached with the PEG-EL-based regimes.

Abstract
The aim of this paper is to evaluate the role of apoptosis in some common liver diseases, and the utility of M30, an apoptotic serum marker, in the diagnosis of the severity of underlying hepatic injury. As is widely known, apoptosis is programmed cell death, and its deregulation results in an uncontrolled inflammatory process leading to upregulation of liver fibrogenesis. Both extrinsic and intrinsic pathways are crucial in apoptosis, and caspase cleavage of cytokeratin proteins occurs in both. Therefore, the measurement of caspase- cleaved cytokeratin fragments could be a novel method to assess the intensity of apoptotic cell numbers in epithelial tissue damage. M30 levels were found to increase not only in acute liver disorders, but also in some chronic liver injuries. We tried to summarize the recent studies focused on the role of apoptotic processes in liver diseases, mainly those that investigated the use of M30 in determining the severity of, or in predicting, ongoing liver injury.

Abstract
BACKGROUND AND AIM The incidence of acute pancreatitis is increasing recently. The aim of this study is to investigate the effect of Ankaferd Blood Stopper (ABS) on experimental model of cerulein induced acute pancreatitis in rats. MATERIALS AND METHODS Forty Wistar Albino rats were divided into five groups. Group 1: Sham (n = 8), Group 2: Control group (n = 8), Group 3: Treatment group (n = 8), Group 4: Prophylaxis group (n = 8), Group 5: Prophylaxis treatment group (n = 8). Any practice was not administered to Group 1. Rats were treated with either 1 ml ABS or 1 ml saline via intraperitoneal route before and after inducing acute pancreatitis. Pancreatic tissues were examined histopathologically. Amylase, cytokines (tumor necrosis factor-α and interleukin-1β), and markers of apoptosis (M30 and M65) were also measured in blood samples. Immunohistochemical staining was performed with caspase 3 antibody. RESULTS We found a statistically significant improvement in histopathological scores in treatment group and prophylaxis group compared with controls. In treatment group, M30 and M65 levels were lower when compared with controls. In prophylaxis group, there was not a statistically significant difference in M30 levels, but M65 levels were lower when compared with controls. CONCLUSION In this experimental acute pancreatitis model, we found high histopathological healing effects of ABS treatment and also prophylaxis. ABS treatment and prophylaxis reduced apoptosis.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is an emerging problem all over the world. Because NAFLD and polycystic ovary syndrome (PCOS) are both closely related with insulin resistance, it would be necessary to determine the rate of presence of NAFLD in PCOS patients. So, this study aimed to investigate the utility of M30 in PCOS patients for the diagnosis of hepatic injury. METHODS Eighty patients with PCOS were included in the study. Ultrasonographic examination for the presence of hepatic steatosis, M30 serum level for determining the severity of ongoing apoptotic cell death in liver, and BARD index for defining the hepatic injury were performed during the study. 25-OH vitamin D and adiponectin level in sera were studied using ELISA (Enzyme-Linked ImmunoSorbent Assay). RESULTS M30 and vitamin D levels did not change significantly with the severity of hepatic steatosis. On the other hand, M30 levels showed a positive correlation with ALT and AST levels, and M30 level suddenly increased with the presence of hepatic steatosis from 159.7 to 170 U/l, however stabilized with the increasing severity of hepatic setatosis. Adiponectin levels decreased with the increasing severity of hepatic steatosis and significantly varied between ALT greater than 40 U/l and less than 40 U/l. CONCLUSIONS M30 level in serum increased with the appearance of hepatic steatosis and had a positive correlation with a noninvasive hepatic injury test, BARD (BMI, aspartate aminotransferase [AST]/alanine aminotransferase [ALT] ratio [AAR], diabetes mellitus [DM]) index. Adiponectin level decreased with the increasing ALT level and severity of hepatic steatosis.

Abstract
Barrett's esophagus (BE) is a complication of chronic gastroesophageal reflux disease and can be diagnosed when there is an endoscopically irregular Z-line and intestinal metaplasia (IM) in a biopsy obtained lower esophagus. It is still not clear whether IM in the gastric cardia or columnar mucosa without IM in the lower esophagus have any significance as BE, which is considered as preneoplastic. The aim of the study was to determine the immunohistochemical features of BE and columnar mucosa in the distal esophagus and also to evaluate the value of chromoendoscopy in the diagnosis of BE in a prospective manner. A total of 12 chromoendoscopic biopsies (six from normal-looking unstained esophagus and six from esophageal mucosa stained with methyl blue suspicious of BE) were taken from 111 cases who underwent endoscopy because of a variety of upper gastrointestinal symptoms. Immunohistochemical analysis was performed using CK7, CK20, p53, Ki67, and cyclooxygenase 2 (COX2). Of the 111 cases, 19 cases with carcinoma (nine adeno, six squamous, four undifferentiated carcinomas) and 17 cases with normal squamous epithelium were excluded, while 75 cases showing columnar epithelium, including 46 (61.3%) with IM and 29 (38,7%) without IM, were further evaluated immunohistochemically. CK7 was observed in surface, crypt, and glandular epithelium, whereas CK20 was expressed in surface and superficial crypt epithelium. No significant difference was observed between the Barrett and non-Barrett type of CK7/20 staining pattern (P > 0,05). Expression of p53 did not show any difference between BE and columnar mucosa without IM, whereas COX2 expression was significantly increased in BE (P < 0.05) in comparison with columnar mucosa without IM. Ki67 expression was significiantly higher both in upper and lower crypts in BE (P < 0.05). The present study showed that a Barrett pattern does not seem to exist; however, the analysis of COX2 expression and the Ki67 proliferation fraction by immunohistochemistry can be used to separate BE from non-Barrett's metaplasia of the distal esophagus. In our point of view, the immunohistochemical detection of p53 expression in Barrett's metaplasia stage is useless as a marker for early detection of high-risk patients.

Abstract
Introduction: Crimean–Congo hemorrhagic fever (CCHF) is a viral tick-borne zoonosis, which is a severe illness, causing hemorrhages in humans. Mean platelet volume (MPV) is used as a surrogate marker of platelet function and has been shown to be a sign of inflammation. The objective of the present study is to examine the association between MPV and CCHF. We also aimed to investigate the association between MPV and coagulopathy markers in the mortality rates and prognosis of patients with CCHF. Patients and Methods: Ninety-three patients with CCHF were enrolled retrospectively into the study and 15 of them were excluded according to the exclusion criteria. Twenty-five healthy individuals were included as a control group which was age and gender matched with CCHF patients. We compared the levels of MPV between the patient and the control groups. We also compared the coagulopathy markers of fatal CCHF patients (n = 9) with nonfatal cases (n = 69). Results: Platelet counts were significantly lower in the CCHF group. Levels of international normalized ratio (INR), prothrombin time (PT), and activated partial thromboplastin time (aPTT) were significantly higher in CCHF group ( P < .001, <.001, <.001, respectively). A statistically significant increase in MPV was observed in patients with CCHF compared with healthy controls (8.63 ± 1.23 fL vs 7.65 ± 0.42 fL, P < .001). Receiver–operating characteristic curve analysis suggested that the optimum MPV level cutoff points for patients with CCHF was 8.15 fL, with a sensitivity and specificity of 65% and 88%, respectively. The MPV levels were not significantly different between group 2 (nonsurvivor) and group 1 (survivor). However, platelet count, d-dimer, INR, PT, and aPTT were also positively correlated with the mortality rates ( P = .008, <.001, <.001, <.001, and <.001, respectively). Multivariable logistic regression model showed an independent correlation between MPV and mortality rate ( P < .001). Conclusion: In conclusion, MPV may be a beneficial marker in the diagnosis of CCHF, especially in cases with thrombocytopenia, the MPV levels are high. We also conclude that MPV may independently predict the prognosis of patients with CCHF.

Abstract
BACKGROUND Hepatocellular carcinoma is a common malignancy for which chronic hepatitis B infection has been defined as the most common etiologic factor. The most frequent metastatic sites are the lung, bone, lymphatics, and brain, respectively. Metastases to the chest wall have been reported only rarely. CASE PRESENTATION We report a patient with hepatocellular carcinoma who presented with an isolated metastatic mass on the left anterolateral chest wall in the axillary region. CONCLUSIONS Metastasis of HCC should be included in the differential diagnosis of rapidly growing lesions in unusual localizations, particularly in patients with chronic liver disease even if a primary tumor can not be radiologically identified.
