Abstract
OBJECTIVE Cardiac masses comprise a category that includes benign, malignant, and nontumoral mass lesions. The present study aims to share the findings relating to cardiac masses observed at our tertiary cardiology hospital in Turkey. METHODS The records of patients who presented with cardiac masses and underwent surgery at our institute between 2006 and 2015, and whose tissue samples were sent to a pathology laboratory, were retrospectively reviewed in a consecutive manner. RESULTS The study included 228 patients with an average age of 52.5 ± 17.3 years. Of the study's subjects, 95 (41.7%) were male and 133 (58.3%) female. The most commonly observed mass was myxoma in 68 patients (29.8%), of whom 20 (29.4%) were male and 48 (70.6%) female. The second most frequently detected mass was pannus, with 38 cases (16.7%) - 10 (26.3%) in males and 28 (73.7%) in females. The third most common cardiac mass was thrombus (16.2%), with 18 cases of thrombi in men (48.6%) and 19 (51.4%) in women. CONCLUSION The most commonly observed cardiac mass was myxoma and most were localized in the left atrium. The second most frequently detected mass was pannus, which was mostly found on mitral mechanical prosthetic valves. Thrombi were the third most prevalent mass and were commonly localized in the right atrium.

Abstract
BACKGROUND Flavonoids have been subjected to considerable investigation because of its antioxidant and anti-inflammatory properties. However, there is no previously reported study about its effect on hepatic ischemia/reperfusion (I/R). We investigated the effects of micronized purified flavonoid fraction (MPFF) on hepatic I/R injury in rats. METHODS Thirty rats were recruited in the study as follows: group A, sham operation (n = 10); group B, I/R (n = 10); and group C, I/R+MPFF (n = 10). In group C, rats received (80 mg/kg/day) MPFF by gavage for 3 days before surgery, 30 minutes before ischemia and just before the reperfusion. Blood samples were taken, and serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) levels were measured to assess liver functions. Liver tissues were taken for histological evaluation and to determine the total antioxidant capacity (TAC), catalase (CAT), total oxidant status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO). RESULTS The present data showed a decrease in AST, ALT, and LDH levels in the MPFF-treated rats when compared with I/R group rats (P < .001 for all). In the MPFF-treated rats, tissue levels of TOS, OSI, and MPO were significantly lower than those in the I/R group (P < .01, P < .001, and P < .05, respectively). Increases in TAC and CAT levels were statistically significant in the MPFF-treated rats compared with the I/R group (P = .01 for both). On the other hand, MPFF attenuated histological alterations that were induced by I/R. CONCLUSIONS The present study demonstrates that MPFF ameliorates I/R-induced liver damage, probably through antioxidant and anti-inflammatory properties.

Abstract
BACKGROUND Results are conflicting with respect to the renal effects of anti-viral agents used for hepatitis B virus infection. AIM To compare short and long-term renal effects in real-life settings and to determine risk factors for renal impairment during treatment. METHODS 2221 treatment-naïve patients were enrolled. Among these, 895 (302 lamivudine, 27 telbivudine, 282 entecavir, 273 tenofovir and 11 adefovir initiated patients) had 'repeated measures' of creatinine (baseline, 1st, 6th, 12th and 24th month of treatment). Telbivudine and adefovir groups were excluded from further analysis because of the low number of patients. We calculated the glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) formula at each time point. Hypophosphataemia was also recorded. Risk factors for renal impairment were analysed. RESULTS Tenofovir caused a decline in GFR at each time point when compared to baseline levels. However, lamivudine and entecavir did not change GFR. GFR-shifting from ≥90 to 60-89 mL/min/1.73 m(2) was comparable among groups. The proportion of patients whose baseline creatinine increased more than 25% was comparable among all anti-virals. GFR showed a decline in patients who switched from entecavir to tenofovir. One patient with compensated cirrhosis needed to change from tenofovir because of renal safety. Seven and three patients developed transient hypophosphataemia in the tenofovir and lamivudine groups, respectively. CONCLUSIONS Although tenofovir caused a decline in GFR, differences between the anti-viral agents do not appear to be so impressive. In patients with and without renal risk factors at baseline, there is no impact of anti-virals, including tenofovir.

Abstract
AIM Laparoscopy is the gold standard procedure in the surgery of gall bladder. Harmonic scalpel and bipolar vessel sealer are the other instruments for laparoscopic cholecystectomy. The aim of this study is to compare the effectiveness and safety of the three instruments for laparoscopic cholecystectomy. METHODS A total of 60 patients were included into the study. Patients were divided into three groups. In Group A, cystic duct and artery were sealed using laparoscopic clips and gall bladder was dissected from the hepatic bed using electrocautery. In Group B, cystic duct and artery were sealed using Harmonic scalpel and gall bladder was dissected from the hepatic bed using Harmonic scalpel. In Group C, cystic duct and artery were sealed using Bipolar vessel sealer and gall bladder was dissected from the hepatic bed using Bipolar vessel sealer. Groups were compared for the following parameters: duration of surgery, amount of drainage, cystic duct opening pressure and cost. RESULTS The duration of surgery was 31.5 ± 11.1 minutes in Group B, 33.1 ± 10 minutes in Group A, and 36.5 ± 9.9 in Group C; and the difference between Group B and Group C was statistically significant (P<0.04). Cystic duct opening pressure was highest in Group A which was 324.0 ± 23.4 mmHg. For all of these 3 groups total cost was found to be 900$, 2900$, 1800$ for groups A, B, and C; respectively. CONCLUSION In laparoscopic cholecystectomy different energy source instruments may be safe to use with a cautious dissection and sealing of the cystic duct.

Abstract
Incidence of the esophagus adenocarcinoma has been dramatically increasing in Western countries since the last decade. Gastroesophageal reflux disease and Barrett's esophagus are risk factors for adenocarcinoma. Methylenetetrahydrofolate reductase (MTHFR) genes play a key role not only in folate metabolism but also in esophagus, stomach, pancreatic carcinoma, and acute leukemias. Studies have suggested that genetic polymorphisms of MTHFR (C677T) may clarify the causes and events involved in esophageal carcinogenesis. In this study, we evaluated MTHFR C677T and A1298C polymorphisms, and vitamin B12, folate, and plasma homocystein levels in patients with esophageal adenocarcinoma (EAC), Barrett's esophagus (BE), chronic esophagitis, and healthy controls (n = 26, n = 14, n = 30, and n = 30, respectively). The mean age of patients in the EAC and BE groups was significantly higher compared with the control group (P < 0.001, P = 0.003, respectively). In all patient groups, serum folate levels were significantly lower than that of the control group (P < 0.01, P < 0.05, and P < 0.01, respectively). There was no statistically significant association between folate levels and MTHFR gene polymorphisms. No differences were found in terms of MTHFR gene polymorphisms, homocystein, and B12 levels among the groups. MTHFR gene polymorphisms and folate deficiency are not predictors of early esophageal carcinoma. However, further studies using larger series of patients are needed to evaluate the effect of genetic polymorphisms in the folate metabolic pathway and to clarify the role of folate deficiency and folate metabolism in the development of esophagus adenocarcinoma.

Abstract
The effects of Ringer lactate, 6% hydroxyethyl starch (130/0.4) or 4% succinylated gelatin solutions on perioperative coagulability were measured by thromboelastography (TEG). Seventy-five patients (ASA I-III) who were to undergo major orthopedic procedures performed under epidural anesthesia were included in the study. Patients were randomly divided into three groups of 25 each for the administration of maintenance fluids: group RL (Ringer lactate), group HES (6% hydroxyethyl starch 130/0.4), and group JEL (4% gelofusine solution). Blood samples were obtained during the perioperative period before epidural anesthesia (t1, baseline), at the end of the surgery (t2), and 24 h after the operation (t3). TEG data, reaction time (R), coagulation time (K), angle value (α), and maximum amplitude (MA) were recorded. TEG parameters changed from normal values in all patients. In group RL, R and K times decreased compared to perioperative values while the α angle and MA increased (P < 0.05). In group HES, R and K times increased, however, the α angle and MA decreased (P < 0.05). In group JEL, R time increased (P < 0.05), but K time, α angle and MA did not change significantly. In the present study, RL, 6% HES (130/0.4) and 4% JEL solutions caused changes in the coagulation system of all patients as measured by TEG, but these changes remained within normal limits.

Abstract
BACKGROUND Currently, although only a few therapies normalize the liver test abnormalities with/without improving the liver histology, no pharmacologic therapy has proved to be effective for the treatment of non-alcoholic steatohepatitis. AIM To investigate the role of insulin sensitizers in the treatment of individuals with non-alcoholic steatohepatitis (NASH). METHODS A total of 74 individuals with NASH (male/female, 44/30; mean age, 47.2 +/- 9.0 years) were enrolled. Participants were divided into two distinct groups: group 1 (n = 25) participants were administered a conventional diet and exercise programme while those in group 2 (n = 49) were administered the diet and exercise programme plus insulin sensitizers. RESULTS With respect to baseline metabolic, biochemical and histological parameters, no significant differences were observed between the two groups (P > 0.05). Insulin sensitizers significantly improved metabolic parameters (homeostasis model assessment-insulin resistance score, P < 0.05), serum aminotransferase levels [aspartate aminotransferase (AST): 45.9 +/- 24.2 to 33.3 +/- 17.7 IU/L, P < 0.01; alanine aminotransferase (ALT): 78.2 +/- 46.3 to 47.3 +/- 34.5 IU/L, P < 0.001] and histological features (median non-alcoholic fatty liver disease activity score: 5.0-3.0, P = 0.01), while diet and exercise improved serum aminotransferase levels (AST: 39.3 +/- 11.1 to 30.0 +/- 8.6 IU/L, P < 0.01; ALT: 66.9 +/- 28.9 to 42.0 +/- 16.2 IU/L, P < 0.001) at the end of the 48 weeks when compared to baseline. Insulin sensitizers improved the high-sensitivity C-reactive protein levels (P < 0.01). No serious adverse effects of insulin sensitizers were observed. CONCLUSION Insulin sensitizers can lead to improvement in metabolic, biochemical and histological abnormalities of NASH as a result of improved insulin sensitivity.

BACKGROUND Barrett's esophagus is a condition that is premalignant for adenocarcinoma of the esophagus and the esophagogastric junction. Early detection of Barrett's metaplasia and dysplasia is very important to decrease the mortality and morbidity from esophageal adenocarcinoma cancer. This study aimed to evaluate the effectiveness of methylene blue-targeted biopsies in the differential diagnosis of intestinal metaplasia, dysplasia, and superficial esophageal carcinoma. METHODS A total of 109 patients (43 women and 66 men; average age, 62.32 +/- 10.61 years; range, 33-82 years) were enrolled for the study. Four groups were designed before endoscopic examinations. The patients for these groups were selected at the conventional endoscopy, and then chromoendoscopy was performed. The esophagus was stained with methylene blue, after which six biopsies were taken from stained and unstained areas. RESULTS Conventional and chromoendoscopic assessments were compared with histopathologic examination. The sensitivity of chromoendoscopy for Barrett's epithelium was superior to that of conventional endoscopy (p < 0.05). However, there was no statistical difference between the two methods in the diagnosis of esophagitis or esophageal carcinoma (p > 0.05). Stained biopsies were superior to unstained biopsies in terms of sensitivity for Barrett's epithelium and esophageal carcinoma (p < 0.001). CONCLUSION Chromoendoscopy is useful for delineating Barrett's epithelium and for indicating the correct location for securing biopsies where dysplasia or early esophageal cancer is suspected.

Abstract
INTRODUCTION Knowledge of first aid, which constitutes life-saving treatments for injuries or unexpected illnesses, is important for every individual at every age. First aid and basic life support are so important that teaching basic first aid should be compulsory in all schools. The goal of this study was to determine the knowledge and attitudes of a sample of Turkish teachers regarding the administration of first aid. METHODS Three hundred twelve teachers took part in this study to evaluate knowledge and attitudes of teachers in primary schools about first aid. Data were obtained using a questionnaire. It included 30 questions that help identify the teachers and determine their knowledge and attitudes about first aid. Data were analyzed by chi-square test. RESULTS In this study, it was determined that most of the teachers do not have correct knowledge and attitudes about first aid. For example, 65.1% of teachers gave incorrect answers regarding epistaxis, 63.5% for bee stings, and 88.5% for abrasion. It was found out that as the age of the teachers increases, appropriate first-aid practice becomes more and more unlikely. DISCUSSION The results of this study showed that teachers did not have enough knowledge about first aid.

Abstract
OBJECTIVE The aims of this study were to evaluate the typing accuracy of conventional smear (CS), cell block (CB) preparations and combined use of both procedures (CS + CB) for the diagnosis of hepatic malignancies and to determine whether immediate on-site cytopathological evaluation improves the diagnostic yield of liver fine-needle aspiration cytology (FNAC). METHODS Ultrasound-guided FNABs were performed on 323 consecutive cases with liver masses between December 2002 and December 2004. Histologically and/or clinically correlated 167 cases were included in the study. Preliminary FNAB results, results of CS, CB, and combined use of CS and CB were compared regarding diagnostic sensitivity, specificity, and accuracy for the diagnosis of malignancy. Subtyping accuracies of different methods were also compared. RESULTS The sensitivity of on-site cytopathological examination and CS were both 92.8%. The sensitivity of CS + CB was slightly better than that of CB (93.5% versus 84.8%). Specificity of all procedures was achieved 100%. Diagnostic accuracy of on-site cytopathological evaluation, CS, CB, and CS + CB were 93.9%, 93.9%, 87.2%, and 94.5%, respectively. A specific subtype diagnosis of malignant tumours could be rendered accurately on the basis of preliminary diagnosis in 71%, CS in 75.4%, CB in 78.3% and combined approach in 92% of cases. In terms of typing accuracy, 87.5% of HCCs, 93.2% of adenocarcinomas, 92.3% of neuroendocrine carcinomas, 100% of lymphomas and 100% of other malignant tumours were correctly subclassified in the final cytopathological diagnosis. The agreement between preliminary diagnosis and final cytopathological diagnosis was 77.2%. CONCLUSION With use of on-site cytopathological evaluation and combined use of CS and CB, the diagnostic accuracy of liver tumours approaches 100% and also significantly improve diagnostic and subtyping accuracy of liver malignancies.

Abstract
The high capacity of liver regeneration after partial hepatectomy (PH) is well known. This study investigated the role of the antioxidant defense system in regeneration among Wistar-albino male rats subjected to 70% partial hepatectomy after a pretreatment period of 2 weeks with eicosapentanoic acid (EPA) rich fish oil (FO), first pressed virgin olive oil (OO), or vitamin E. The control group of 10 rats underwent PH only. On postoperative day 3, all rats were humanely killed. Liver sections of animals treated with FO or vitamin E showed significant increases in regeneration within both liver parenchyma and cut surface compared with the control group (P < .05). Liver sections of OO displayed an insignificant increase in liver regeneration (P > .05), with less increase in parenchyma than of the cut surface. The enhancement of the liver parenchymal regeneration in the FO group was significantly greater than that of the vitamin E group. Concerning liver function tests (LFT), there was no significant difference among the groups. When the treatment groups were compared to the control group glutathione (GSH) levels were increased and content of malondialdehyde (MDA), nitric oxide (NO), and superoxide dismutase (SOD) were decreased. Based on these results, we concluded that after 70% PH in rats, the liver parenchyma and cut surface regeneration were greatest with FO and least with OO treatment. Both FO and vitamin E served to improve the antioxidant defense system more than OO treatment.

Abstract
Immunosuppressants are the cornerstones of treatment after solid organ transplantation. This study investigated the pathology and cell proliferation following partial hepatectomy (PH) in rats undergoing immunosuppressive treatment. After 1 day, all rats were subjected to 70% PH. Groups A and B (n = 10) received calcineurin inhibitors subcutaneously: either FK506 or cyclosporine (CyA). Groups C and D (n = 10) received antiproliferative drugs: either mycophenolate mofetil (MMF) or sirolimus (SRL) by gavage. A control group (n = 5) received 1 mL of tap water daily. On postoperative day 2, all rats were sacrificed to obtain liver tissue for pathologic examination. Using immunohistochemistry we separately examined the hepatectomy surface and the liver parenchyma. In the parenchyma, the Ki-67 indices were higher in the CyA and FK506 groups and lower in the SRL and MMF groups compared with controls (P < .01). CyA had the highest and MMF the lowest values. On the hepatectomy surface, Ki-67 indices and TGF-alpha expressions were higher in the CyA group and lower in the SRL and MMF groups compared with the control group (P < .01). Slightly higher values in the FK506 group were not significantly different compared with the control group (P > .05). All groups other than FK506 showed prominent cholangiolar epithelial phenotypes compared with the control group. In the CyA and SRL groups, the number of cholangiolar cells was higher (P < .01), and in the MMF group lower than in the control group (P < .01). Among all groups, SRL had the highest values.

Abstract
The case of a 58-year-old woman who was diagnosed with the localized type of Caroli's disease is presented. This disease involves the whole of the left half of the liver. A left hepatectomy was followed by complete resolution of symptoms. The current article suggests that hepatic resection may be aggressively performed in selected patients with the localized form of Caroli's disease.

Abstract
The alternatives for prophlaxis and treatment of recurrent hepatitis B virus infection have increased since new oral nucleoside analogues have become available. We conducted this experimental study to investigate the effect in the liver of these agents on the expression of transforming growth factor alpha (TGF-alpha) and on proliferation index, estimated by Ki-67. Thirty male Wistar albino rats were randomized into three groups: group A (n = 10) received adefovir dipivoxil (40 mg/kg/d per gavage); group B (n = 10), lamivudine (L; 30 mg/kg/d per gavage); and group C (n = 10) did not receive any treatment and were the control group. Groups A and B were treated for 3 days. Animal treatment began on day -1. After performing 70% partial hepatectomy on day 0, all rats were sacrificed on postoperative day 2 to harvest liver tissues for histopathological examination. We stained and indexed Ki-67 and TGF-alpha immunohistochemically on the hepatectomy surface and in the parenchyma, Ki-67 and TGF-alpha indices were significantly higher in group A compared with group B (P = .001 and P = .004, respectively, and P = .003 and P = .001, respectively). When the L group was compared with the control group for results on the hepatectomy surface and the parenchyma, Ki-67 and TGF-alpha indexes were insignificantly different (P = .6 and P = .3, respectively, and P = .1 and P = .6, respectively). Based on the results of this experimental study, we concluded that Adefovir dipivoxil has greater proliferative effect on liver parenchyma and in the cut surface than does lamivudine.
