RESUMO
BACKGROUND: Liver biopsy is an invasive procedure that is currently still necessary for predicting underlying hepatic injury related to chronic viral hepatitis B (CVHB). To date, none of the studied non-invasive methods have been able to replace liver biopsy. An apoptotic serum marker, M30, which has been reported to indicate ongoing liver fibrosis, has been popular in recent years. OBJECTIVES: We aimed to investigate the possible role of M30 in predicting CVHB-associated hepatic injury and its severity. METHODS: Forty-eight patients undergoing liver biopsy for evaluation of the severity of CVHB-related liver injury and 40 healthy controls were included in this cross-sectional study. M30 levels were determined for all CVHB patients and controls, and other laboratory parameters and demographic features were obtained from our hospital's database. RESULTS: The mean ages of patients and controls were 39.7 and 45.7 years, respectively, and 35% of the controls and 52% of the patients were male. In contrast to lower platelet counts, transaminase and M30 levels were both higher in the patient group than in the controls. Among the investigated parameters, only transaminase increased as the fibrosis stage changed from mild to moderate; however, none of the laboratory parameters, including M30, differed as the histological activity index (HAI) score increased. CONCLUSIONS: M30 levels were higher in CVHB patients compared to healthy controls. However, M30 levels were similar in the mild and moderate stages of fibrosis, so they did not indicate the severity of underlying fibrotic or inflammatory processes in CVHB patients.
RESUMO
BACKGROUND/AIM: Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine. To our knowledge, no studies to date pertain to the profile of nail changes in IBD, except for onychomycosis. We aimed to study the frequency and pattern of nail changes among patients with IBD and evaluate their potential relationships with several parameters in IBD. MATERIALS AND METHODS: The study included 73 patients with IBD and 51 healthy control subjects. Nails of both groups were examined for changes with regard to color, striations, texture, curvature of nail plates, dystrophy of nail plates, and pigmentation. Mycological examinations were performed when onychomycosis was suspected. RESULTS: Nail changes were statistically higher in patients with IBD than in the control group (P = 0.001). The presence of onychomycosis was significantly more common in patients with IBD (P = 0.041). Subungual hyperkeratosis and brownish discoloration of the nail were the most common findings in patients with IBD. CONCLUSION: Our study is the first report showing all nail changes in IBD. Further studies with more subjects are needed to reveal more detailed information about nail changes in IBD.

Objective Patients with ulcerative colitis (UC) are at an increased risk for thromboembolic events, particularly in patients with extensive and active disease. To date, a few studies have been published on the role of thrombin-activatable fibrinolysis inhibitor (TAFI) in UC. However, there are no reports in the literature investigating the effect of UC treatment on plasma TAFI levels. Methods The plasma TAFI antigen levels were quantitatively determined using ELISA kits for 20 UC patients at activation and remission, along with 17 healthy controls. The association between the TAFI levels and inflammatory markers was assessed to determine UC activation. To predict and determine the activation of UC, the Truelove-Witts index and the endoscopic activation index (EAI) were used for each subject. Results The plasma TAFI levels were higher in UC patients at activation of the disease compared with the remission state and in healthy controls. Spearman's correlation analyses revealed that the WBC (r: 0.586, p<0.001), hsCRP (r: 0.593, p<0.001) and EAI (r: 0.721, p<0.001) were significantly correlated with the TAFI levels. The overall accuracy of TAFI in determining UC activation was 82.5% with a sensitivity, specificity, NPV and PPV of 80%, 85%, 81% and 84.2%, respectively (cut-off value: 156.2% and AUC: 0.879). Conclusion The present study demonstrates that the TAFI levels are elevated in the active state of UC. The assessment of TAFI levels in patients with UC in conjunction with other markers of inflammation may provide additional information for estimating UC activation and severity.

BACKGROUND AND AIM: Liver biopsy is the gold standard for assessment of fibrosis in patients with hepatitis B. However, it has some disadvantages, including inter-observer and intra-observer variability in biopsy interpretation and specimen variation. A standard biopsy specimen represents only about 0.0002 % of the whole liver. It has been shown that two biopsy samples collected during a procedure have significant influence on the diagnostic performance of interpretation in patients with hepatitis C or non-alcoholic steatohepatitis. Therefore, we aimed to assess the influence of collecting two liver biopsy samples during a single procedure for staging and grading chronic hepatitis B. PATIENTS AND METHODS: 27 patients were included in the study. The median age of the patients was 43.51 ± 11.69. Fifteen patients were female, 12 patients were male. In the biopsy procedure, two samples of liver lobes were obtained. Grade and stage scores were compared between the two samples. Fibrosis staging and grading were assessed according to the Ishak scoring system. RESULTS: Numbers of portal tract and biopsy size were equal in the two samples. There was a significant difference between the samples in terms of histological activity index (p value = 0.04). However, the difference was not enough to distinguish the mild and moderate stages. On the other hand, no significant difference in fibrosis staging between the two samples was found. CONCLUSIONS: With this relatively small size of patients, in this study, we showed that a proper liver biopsy size is sufficient to predict treatment decisions in chronic hepatitis B patients. However, further studies are needed to show the association of sampling variability in patients with hepatitis B.

The most common metastatic sites of colorectal cancer are liver, lung, peritoneum and lymph nodes. Metastasis of colorectal carcinoma to palatine tonsil is rarely seen. To our knowledge, only 11 patients were documented in English literature. Atypical metastases can sometimes lead to misdiagnosis. Precise diagnosis of atypical metastases requires a careful physical examination, good imaging method and comprehensive pathological evaluation. Here, we report a case of rectal adenocarcinoma presented with palatine tonsil metastasis.

Chronic viral hepatitis B (CHB) is an important cause of morbidity and mortality. Adipokine stimulation might play an important role in the pathogenesis of chronic inflammation. The aim of this study was to evaluate serum visfatin concentrations and the relationship between visfatin, fibrosis, liver inflammation, and acute phase reactants in CHB patients.The sampling universe of the study consisted of 41 CHB patients and 25 healthy controls. All patients had positive hepatitis B surface antigen (Hepatitis e antigen (HBeAg) positive n: 7, n: 34 HBeAg negative) for at least 6 months and detectable serum HBV DNA. Serum visfatin concentrations were significantly higher in the CHB patients [18.0 ± 10.9 ng dL(-1)] than in the healthy controls [9.4 ± 1.6 ng dL(-1)] [P < 0.001]. On the other hand, fibrinogen and haptoglobin concentrations were significantly lower in CHB patients. A strong negative correlation was observed between serum visfatin concentration, haptoglobin, and fibrinogen levels; however, there was no significant correlation between visfatin, glucose, alanine aminotransferase, aspartate aminotransferase, BMI, Knodell score, fibrosis score, hepatitis B virus DNA, sedimentation, and C-reactive protein. Visfatin concentrations were elevated and visfatin was negatively correlated with haptoglobin and fibrinogen levels in CHB patients.

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, Yenisehir Laboratuari, 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.

OBJECTIVE: The aim of this study was to determine whether there is an association between cagA [cytotoxin-associated gene A] positivity and thyroid autoimmunity and thyroid volume. METHODS: This prospective study included 78 Helicobacter pylori-positive (H. pylori) dyspeptic patients in the study group, and 50 age-, gender-, and body mass index-matched H. pylori-negative dyspeptic patients in the control group. All the controls were evaluated via upper gastrointestinal endoscopic biopsy or breath test, and were found as H. pylori negative. Gastric biopsy specimens were obtained via endoscopy and histological examination was performed for documentation of H. pylori. RESULTS: In all, 55.1% (n = 43) of the H. pylori-positive patients were cagA positive. There was no significant difference in metabolic syndrome parameters or thyroid function test results between the study and control groups. The frequency of anti-TPO and Hashimoto's thyroiditis positivity was significantly higher in the study group than in the control group. Thyroid volume was higher and severe parenchymal heterogeneity was more common in the H. pylori-positive patients. CONCLUSIONS: H. pylori infection might be a risk factor for autoimmune thyroid disease and high thyroid volume in patients diagnosed with histological evaluation. However, cagA positivity has no additional effect on these parameters.

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-1ß), 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.
RESUMO
BACKGROUND AND AIM: Early detection of fibrosis should be the main goal of treatment in liver cirrhosis. Endocan, previously called endothelial cell specific molecule-1, is expressed by endothelial cells, primarily in the lung, liver and kidney. In this study, we aimed to examine the correlation of liver fibrosis stage, histological activity and grade of steatosis between serum levels of endocan in patients with chronic hepatitis B (CHB), chronic hepatitis C (CHC) and non-alcoholic fatty liver disease (NAFLD). PATIENTS AND METHODS: This cross-sectional study includes a total of 146 subjects. 55 CHB patients, 19 CHC patients, 38 NAFLD patients and 34 healthy controls were enrolled consecutively. Liver biopsies were performed in all patients with chronic viral hepatitis. NAFLD patients had either grade 2 or grade 3 steatosis on ultrasonography and elevated liver enzymes above the upper normal limits. Serum endocan levels were assessed from blood samples obtained at admission. RESULTS: Gender distribution was similar among the groups (p=0.056). The mean age of the CHB patients was 45.8±12.1, CHC patients was 55.0±12.8 years, NAFLD patients was 42.8±10.8, while control group was 39.4±13.6 years old. Patients with CHC were older than all the others (p=0.001). Serum endocan levels were statistically significantly lower in CHB, CHC and NAFLD groups when compared with controls. Although levels of endocan were lower in CHB and CHC groups when compared with NAFLD group, the difference was not statistically significant. CONCLUSION: Serum endocan concentrations decrease in patients with liver disease. Unlike previous studies, we showed a negative correlation between endocan levels and inflammation stage of chronic hepatitis. However, further studies are needed to establish the association between endocan levels, liver fibrosis and hepatic inflammation.
RESUMO
Acute pancreatitis is the acute inflammation of pancreas and peripancreatic tissues, and distant organs are also affected. The aim of this study was to investigate the effect of Urtica dioica extract (UDE) treatment on cerulein induced acute pancreatitis in rats. Twenty-one Wistar Albino rats were divided into three groups: Control, Pancreatitis, and UDE treatment group. In the control group no procedures were performed. In the pancreatitis and treatment groups, pancreatitis was induced with intraperitoneal injection of cerulein, followed by intraperitoneal injection of 1 ml saline (pancreatitis group) and 1 ml 5.2% UDE (treatment group). Pancreatic tissues were examined histopathologically. Pro-inflammatory cytokines (tumor necrosis factor-α), amylase and markers of apoptosis (M30, M65) were also measured in blood samples. Immunohistochemical staining was performed with Caspase-3 antibody. Histopathological findings in the UDE treatment group were less severe than in the pancreatitis group (5.7 vs 11.7, p = 0.010). TNF-α levels were not statistically different between treated and control groups (63.3 vs. 57.2, p = 0.141). UDE treatment was associated with less apoptosis [determined by M30, caspase-3 index (%)], (1.769 vs. 0.288, p = 0.056; 3% vs. 2.2%, p = 0.224; respectively). UDE treatment of pancreatitis merits further study.
