Abstract
Background/aim Familial Mediterranean fever
(
FMF) is a disease that is mainly diagnosed with clinical features. Several well-known inflammatory markers increase in FMF. However, there is still a need for diagnostic tests for specifying FMF and monitoring inflammatory activity. CXCL16 is a chemokine produced by inflammatory cells that demonstrate efficacy in the acute phase response. In this study, we aimed to investigate the relationship between CXCL16 levels and FMF disease and to evaluate CXCL16 levels as a novel biomarker for FMF. Materials and methods Fifty-three male patients diagnosed with FMF and sixty healthy individuals were included in this cross-sectional study. Blood samples were taken in the first 24 h of the attack periods. Serum soluble CXCL16 was evaluated by enzyme-linked immunosorbent assay (ELISA) method. Results CXCL16 (P < 0.001), erythrocyte sedimentation rate (P < 0.001), C-reactive protein (P < 0.001), and fibrinogen (P = 0.005) were significantly higher in FMF group than in control group. Receiver operating characteristic (ROC) curve analysis revealed a cut off value of CXCL16 as 2.68 ng/ml with 83% sensitivity and 68% specificity (P < 0.001). Logistic regression analysis indicated that high CXCL16 and erythrocyte sedimentation rate levels were predictive parameters for FMF disease (OR 8.31; 95% CI 2.59-26.62; p <0.001) (OR 1.27; 95% CI 1.12-1.44; P < 0.001). There was no correlation between CXCL16 levels and attack frequency and disease duration (P = 0.395, P = 0.956). Conclusion To the best of our knowledge, this is the first study evaluating serum soluble CXCL16 levels as a biomarker for FMF. CXCL16 levels were significantly higher and were predictive for monitoring inflammatory activity in patients with FMF. CXCL16 may be a promising biomarker for FMF diagnosis.

Abstract
BACKGROUND AND AIM Viral hepatitis is the most important cause of chronic hepatitis worldwide. Stigmatization is defined as a feeling of rejection and isolation of patients by society due to illness. There are no studies on chronic viral hepatitis in the literature in English, which has its own religious and socio-cultural structure. In our study, we aimed to investigate the presence of social stigmatism and psychosocial effects on patients with different stages of chronic viral hepatitis B and C. METHODS Forty-five patients with chronic hepatitis C and 114 patients with chronic hepatitis B were enrolled in the study. Berger's scale was used for stigmatization, composed of 40 four-point Likert items that have four subscales: personalized stigma, disclosure, negative self-image, and public attitude. Stigma score ranges between one and four. Stigma is accepted as present if the overall score is above two. RESULTS Overall the mean stigma scores were 1.97±0.58 and 2.14±0.57 for chronic hepatitis B and C, respectively. There was stigma in 47.4% of the patients with chronic hepatitis B, and 60% of the patients with chronic hepatitis C. Being male was the risk factor on overall stigma, disclosure and public attitude in chronic hepatitis C. Living in an urban setting was the risk factor on negative self-image in chronic hepatitis C and on personalized stigma and disclosure in chronic hepatitis B. CONCLUSIONS To the best of our knowledge, this is the first study that provides qualitative information about chronic hepatitis-related stigma. Stigmatization is a major problem in Turkey and worldwide. We believe that increasing the knowledge of the patients and society by teaching about the transmission routes of the disease and focusing on vaccination studies will prevent stigmatization.

Abstract
Drug-induced liver injury (DILI) is an important cause of morbidity and mortality. DILI can even cause acute liver failure and the need for liver transplantation. Identifying DILI may be particularly difficult because it is actually an exclusion diagnosis and individuals are usually exposed to several drugs during a lifetime. Causality assessment methods are needed for objective diagnosis. The most common methods are; updated Roussel Uclaf causality assessment method (RUCAM), Narenjo adverse drug reaction probability scale and Maria and Victorino (M&V) causality assessment scale. Phenprobamate is a widely used muscle relaxant. Herein we report a rare case of repeated DILI caused by phenprobamate and review the objective diagnostic process for hepatotoxicities. Physicians should be aware of the potential adverse effects of this drug, including hepatotoxicity. How to cite this article: Duzenli T, Tanoglu A, et al. Drug-induced Liver Injury Caused by Phenprobamate: Strong Probability Due to Repeated Toxicity. Euroasian J Hepatogastroenterol 2019;9(1) :49-51.

Abstract
BACKGROUND AND STUDY AIMS There is still a debate about the exact measurement of the oesophagogastric junction and the diaphragmatic hiatus among clinicians. The aim of this study was to investigate the differences between landmark readings of gastroscopy on intubation and extubation, and to correlate these readings with a gastro-oesophageal reflux questionnaire. PATIENTS AND METHODS 116 cases who underwent diagnostic gastroscopy between January 2013 and June 2013 were included in this study. Landmark measurements were noted while withdrawing the endoscope and were also evaluated after the gastric air was fully emptied. We first used a frequency scale for the gastro-oesophageal reflux disease symptoms (FSSG) questionnaire in order to investigate dysmotility and acid reflux symptoms in the study population and correlated the FSSG questionnaire with intubation and extubation measurements at endoscopic examination. RESULTS Mean age of included subjects was 49.41±17.7 (19-82) years. Males and females were equally represented. On FSSG scores, the total dysmotility score was 7.99±5.06 and the total score was 15.18±10.11. The difference between intubation and extubation measurements ranged from -3cm to +2cm (mean: -0.4). When an FSSG score of 30 was accepted as a cut-off value, we detected a significant difference between the measurements (p<0.05; t: 0.048). CONCLUSION Accuracy of landmark measurements during gastroscopy is clearly affected from insertion or withdrawal of the endoscope. When differences in measurements between insertion and withdrawal were evident, comparable with the FSSG scores, the results became significantly different. In conclusion, according to FSSG scores, these measurements should be performed at the end of the endoscopy.

Abstract
BACKGROUND/AIMS We aimed to semi-quantitatively investigate prohibitin-2 (Phb-2) and stomatin-like protein-2 (Slp-2) expressions in patients with ulcerative colitis (UC) and healthy controls using the immunohistochemical (IHC) method. We also aimed to evaluate the correlations between the activity of UC and the expressions of these two proteins. MATERIALS AND METHODS Ninety-five patients with UC (82 males and 13 females) and 38 healthy controls (35 males and 3 females) were included. Clinical and endoscopic activities of UC were assessed. Conventional laboratory activation parameters and severity of inflammation measures were used for the evaluation of histological activity. IHC staining of biopsy samples for the two proteins were semi-quantitatively applied, similar to previously described methods for colon adenocarcinomas. RESULTS IHC scores of Phb-2 were lower but Slp-2 scores were higher in the UC group than in the healthy controls (p<0.05 and p=0.003, respectively). Phb-2 scores were positively correlated with clinical and histological activities (r=0.364, p<0.05 and r=0.220, p<0.032, respectively). In the UC group, endoscopic activity scores, C-reactive protein levels, and sedimentation rates were also positively correlated with Phb-2 scores (r=0.279, p<0.05, r=0.216, p<0.05, and r=0.216, p<0.05, respectively). IHC scores of Slp-2 were not significantly correlated with the activity parameters of UC. However, there was a significant positive correlation between the expressions of Phb-2 and Slp-2 proteins (p<0.001). CONCLUSION Phb-2 may serve as a valuable new biomarker for predicting the severity of all UC activity parameters. The therapeutic effectiveness of both Phb-2 and Slp-2 should be taken into consideration.

Abstract
INTRODUCTION Gastroenterology units have faced a major increase in referrals for PEG insertion over the last decade. For this reason we decided to review our PEG insertion procedures with regard to indications, complications and follow-up. MATERIALS AND METHODS The indications, success of procedure, complications, long-term results of PEG in patients of Gulhane Military Medical Academy, Haydarpasa Training Hospital between October 2002 and April 2009 were retrospectively evaluated. RESULTS 81 patients had undergone PEG insertion and follow-up information has been available for 77 patients. 40 were men with the mean age of all patients 70.74 ± 20.82 (range 20 to 104 years). PEG was successfully placed in all patients except in one patient who had gastric bleeding during the procedure. There was only one mortality related with the placement procedure. The most common indication for PEG was neurologic disorders in 71 (92%) patients. Other indications were head and neck cancers in 6 (8%) patients. Median follow-up period was 12 months (range, 3 days to 78 months). PEG related complications were seen in only 14 patients (18.2%) in 16 events with a total complication rate as 21%. CONCLUSIONS PEG placement is a safe procedure and well-tolerated with a low mortality and complication rate even in older patients who have multiple co-morbidities under adequate precautions.

Abstract
Benign recurrent intrahepatic cholestasis (BRIC) is a rare autosomal recessive or sporadic disorder, characterized by recurrent episodes of intense pruritus and jaundice that resolve spontaneously without leaving considerable liver damage. The attacks can start at any age, but the first attack is usually seen before the second decade of life. We report the case of a young adult male patient with BRIC who presented with recurrent cholestatic jaundice and pruritus with negative work up for all possible etiologies and a liver biopsy consistent with intrahepatic cholestasis. He improved on treatment with rifampicin and has not suffered another attack on follow up. Although in adulthood, BRIC diagnosis should be kept in mind in patients with recurrent cholestatic attacks with symptom free intervals after main bile duct obstruction and other congenital or acquired causes of intrahepatic cholestasis excluded.

Abstract
This study was conducted to establish the functions and oxidative stress status in leukocytes of adult patients with nephrotic syndrome. Thirty adult patients with nephrotic syndrome and 32 controls were included. Phagocytosis ability, the killing ability of the micro-organism phagosited of polymorphonuclear leukocytes (PMNL) and monocytes, along with oxidative stress parameters of PMNLs were assessed. There was no statistically significant difference in phagocytosis function of PMNLs and monocytes of patients when compared to those of controls. PMNL burst activities of the patient and control groups also showed no difference; however, the monocyte burst activities of patients were significant (p = 0.012). The glutathione peroxidase (GSH-Px) activities in PMNLs of the patients with nephrotic syndrome were significantly higher (p = 0.026) when compared to those of controls. In comparison with those of the control subjects, the patients had also higher selenium levels in their PMNLs (p < 0.001). Although PMNL malonyldialdehyde (MDA) levels of the patients seem to be higher than those of controls, the difference had no statistical significance (p = 0.071). Conclusively, in the patients with nephrotic syndrome, PMNLs appear to be exposed to an oxidative stress as indicated by their increased GSH-Px activities and selenium content. However, PMNLs in nephrotic syndrome patients seem to be coping with the insulting oxidative stress, as suggested by their near-normal MDA productions. Furthermore, these data suggest that nephrotic syndrome appears not to have an influence on phagocytosis and killing abilities of granulocytes and monocytes as long as these cells can overcome the oxidative stress to which they are exposed in this disease.

Abstract
This article describes a patient who underwent right ventricular disconnection for medically refractory ventricular tachycardia associated with arrhythmogenic right ventricular dysplasia. After the operation there was no ventricular tachycardia recurrence. Two years after the operation, he received a permanent VVI pacemaker for the symptomatic second-degree AV block. Sensing function of the pacemaker was normal for the normal QRS complexes, but the tiny QRS complexes that appeared after the arrhythmia surgery were not sensed by the pacemaker and therefore caused no problem.

Abstract
BACKGROUND Restenosis after percutaneous transluminal coronary angioplasty (PTCA) is a major problem limiting the long-term efficacy of the procedure. The purpose of this study was to determine whether risk factors such as cigarette smoking, diabetes mellitus, hypertension or hypercholesterolaemia correlate with restenosis after PTCA. We also studied the relationship between a history of previous myocardial infarction and the extent of coronary artery disease (single-, two- or three-vessel) with restenosis after coronary angioplasty. METHODS A total of 360 patients underwent successful PTCA. Follow-up coronary angiograms were performed in 181 patients after a mean +/- SD period of 6 +/- 4 months. RESULTS The restenosis rate was 49%. We divided the patients into two groups: 89 patients with restenosis (8 women and 81 men) and 92 patients with no restenosis (14 women and 78 men). Age, sex, a history of cigarette smoking, diabetes mellitus and a history of previous myocardial infarction were not associated with restenosis. Serum levels of triglyceride were also unrelated to the restenosis rate. Restenosis was associated with hypertension, low levels of high-density-lipoprotein cholesterol, high levels of low-density-lipoprotein cholesterol and high total cholesterol levels (P < 0.001). Patients with two-vessel or multivessel disease had significantly higher restenosis rates than patients with single-vessel disease (P < 0.001). CONCLUSION Patients with hyperlipidaemia, hypertension and multi-vessel disease appear to be higher risk of recurrent restenosis.

Abstract
The in vitro effect of nicotine (10(-7) mol l-1) on red blood cell (RBC) deformability in essential hypertension, efficacy of antihypertensive treatment (with the combination of enalapril, nifedipine and indapamid) on hypertension-induced decrease in RBC deformability and interaction between nicotine and efficacy of antihypertensive treatment were investigated in the blood samples obtained from 16 patients with untreated hypertension (UH) and 18 patients with treated hypertension (TH). Fourteen healthy subjects served as normotensive (NT) group. RBC deformability was assessed by using a gravity-driven microfiltration technique. In the UH group, the RBC deformability was found to be significantly lower than those in NT (0.623 +/- 0.06 versus 0.753 +/- 0.078, p < 0.001) and in TH (0.623 +/- 0.06 versus 0.732 +/- 0.055, p < 0.001) groups. The RBC deformability in the TH group was not significantly different than that in the NT group (0.753 +/- 0.078 versus 0.732 +/- 0.055, p > 0.05). Nicotine, in vitro, decreased deformability in the NT (0.668 +/- 0.067 versus 0.753 +/- 0.078, p > 0.0001), UH (0.509 +/- 0.052 versus 0.623 +/- 0.06, p < 0.0001) and TH (0.651 +/- 0.046 versus 0.732 +/- 0.055, p < 0.001) groups. The effect on the UH group was significantly greater than those in the NT (p < 0.0001) and TH (p < 0.0001) groups. These results suggest that nicotine and hypertension independently and cumulatively decrease the RBC deformability and nicotine inhibits the efficacy of antihypertensive treatment on RBC deformability.

Abstract
The aim of this study was to determine the value of U wave polarity in the electrocardiograms of patients with atherosclerotic heart disease. One hundred twelve consecutive patients with U waves were entered into the study. Forty-eight of them had unstable angina pectoris and 64 had prior myocardial infarction (MI) (20 patients had inferior MI, 35 had anterior MI, and 9 had non Q wave MI). Each of these subgroups was divided into two groups with positive (group 1) and negative (group 2) U waves. All patients in this study underwent routine left ventriculography and coronary angiography. The authors examined coronary arteries and calculated ejection fractions. The authors discovered that patients with unstable angina pectoris or anterior MI (group 2) had three-vessel disease more frequently (P < .05). Also, in these patients, there was more than 90% diameter narrowing in the left anterior descending vessel more frequently (P < .001 in unstable angina pectoris and P < .05 in anterior MI). In patients with unstable angina pectoris, inferior MI, or anterior MI, the authors observed that the ejection fraction was lower in group 2 than in group 1 (P < .001 in unstable angina pectoris, P < .05 in inferior MI, and P < .05 in anterior MI). The authors suggest that negative U waves in patients with unstable angina pectoris or anterior MI may indicate multivessel disease with a severe left anterior descending lesion. Also, in patients with unstable angina pectoris, inferior MI, or anterior MI who had negative U waves, ejection fraction was reduced.

Abstract
The high frequency mid-QRS potentials and late potentials are important in coronary artery disease because they are related to the extent of ischemia and prognosis. In this study, the effects of successful percutaneous transluminal coronary angioplasty (PTCA) on these potentials were evaluated. Twenty-four patients with coronary artery disease (aged 34-67 years, 5 women, 19 men) were examined. Eight of these patients had a history of myocardial infarction (4 anterior, 3 inferior, 1 anterior and inferior). Signal averaged ECG was recorded at 40- to 250-Hz frequency ranges for late potentials and 150- to 250-Hz frequency ranges for mid-QRS potentials before PTCA, and they were repeated 1 month later. The QRS duration (107.7 +/- 9.8 to 105.3 +/- 9.3 ms, p < 0.0001) root-mean-square voltage (39.4 +/- 20.1 to 47.7 +/- 22.2 microV, p < 0.00001) and low amplitude signal duration (30.7 +/- 9.9 to 27.7 +/- 9.3 ms, p < 0.001) showed significant changes in 40- to 250-Hz ranges before and after PTCA. The same results were also obtained in the 150- to 250-Hz frequency ranges: the QRS duration decreased (90.9 +/- 9.8 to 86.5 +/- 9.1 ms, p < 0.005) and the root-mean-square voltage increased (5.5 +/- 1.6 to 6.1 +/- 1.8 microV, p < 0.00001). Thus, successful PTCA causes improvement in late potential parameters, so the risk of malign arrhythmia that affects the prognosis can be reduced. Additionally, the increase in high frequency mid-QRS potentials shows the decrease in the ischemia after PTCA.

Abstract
The relationship between cardioinhibitory response to the carotid sinus massage and the severity of coronary artery lesions and left ventricular impairment was investigated in 86 patients who underwent coronary angiography. The study group (Group 1) comprised 63 patients who had coronary lesions and the control group (Group 2) comprised 23 patients who had normal coronary arteries. There was no significant relationship between the severity of coronary artery lesions and the cardioinhibitory response to the carotid sinus massage in the study group. However, there was a positive correlation (r = 0.478, P < 0.01) between total left ventricular segment scores and the maximal change in RR interval (%) during the right carotid sinus massage in the study group. During the right carotid sinus massage, maximal change of RR interval (%) was significantly higher in patients who had segmental wall motion abnormalities than in patients who did not (83.0 +/- 72.4% vs. 32.9 +/- 42.5%, P < 0.01, respectively). In the patients who could have echocardiographic measurements there was negative correlation between fractional shortening value and maximal change of RR interval (%) (right massage; r = -0.482, P < 0.01, left massage; r = -0.334, P < 0.05). In conclusion, we found a significant relationship between the cardioinhibitory response to carotid sinus massage and the presence and severity of the segmental wall motion abnormalities and left ventricular impairment in patients with coronary artery disease.

Abstract
To determine the immediate and remote prognostic significance of bundle branch block (BBB) associated with acute myocardial infarction (AMI), 40 patients with AMI and BBB were studied. One hundred forty-four patients with AMI but without BBB were evaluated during the in-hospital phase and 45 of them were taken as a control group. These patients were followed for an average of 15 months (3-28 months). Arrhythmias and left ventricular function were investigated with 24-hr Holter monitoring and echocardiography, respectively. The hospital mortality was significantly greater in patients with BBB than in the control group (32.5% vs 10.4%, p < 0.001). The main cause of mortality was pump failure in the group with BBB (76.9%) and ventricular fibrillation in the control group (53.3%). The peak creatine kinase level was significantly higher in the group with BBB than in the control group (2094.8 +/- 288.4 IU/L vs 416.7 +/- 30.5 IU/L, p < 0.001). In patients with BBB prophylactic temporary pacemaker insertion was not found to improve the hospital mortality rate. In the hospital phase, although 32% of the patients with BBB had complicated arrhythmias (multiform, paired VPB, runs, R-on-T) the cause of death in 10 of the 13 patients who died was pump failure but not arrhythmia. In patients with BBB the wall motion index and the number of patients who had a left ventricular aneurysm were greater than in patients without BBB (9.5 +/- 0.9 vs 6.3 +/- 0.6, p < 0.01 and 52.0% vs 14.3%, p < 0.01, respectively). In patients with BBB follow-up mortality (12.0%) was lower than hospital mortality (32.5%). During the follow-up period there was no significant difference between patients with BBB and those without with regard to complicated arrhythmias (14.8% vs 15.6%). These results indicate that the main cause of poor prognosis during the hospital period in patients with AMI and BBB was not arrhythmia or conduction disturbance but severe pump failure due to extensive myocardial necrosis. Prophylactic temporary pacemaker insertion did not improve the hospital mortality rate of these patients, and patients with AMI and BBB who survive the in-hospital phase after infarction have a good prognosis during the following 15 months.

Abstract
The interaction between amiodarone and the defibrillation threshold (DFT) is still controversial. We present a case with dilated cardiomyopathy and recurrent sustained monomorphic ventricular tachycardia who received an automatic implantable cardioverter defibrillator (AICD) while under long-term amiodarone treatment. AICD implantation was performed without thoracotomy. The transvenous lead was inserted via a left subclavian vein puncture and the patch was placed on the lateral chest wall, submuscularly. At the time of implantation a 35J shock was not successful in converting ventricular fibrillation to sinus rhythm, but a 40J rescue shock was successful. After discontinuation of amiodarone, DFT measurements were repeated. Sixteen days later DFT was still higher than 34J, but 71 days later it decreased to 20J.

Abstract
We studied the values of oral dipyridamole needed to detect coronary arterial disease using 12-lead electrocardiography. The relationship between dipyridamole-induced ST segment depression and coronary arterial lesions, coronary collaterals and myocardial infarction was investigated. 375 mg oral dipyridamole was given to 31 patients (22 with coronary arterial disease, 9 controls). 12-lead electrocardiogram was recorded before and 45 minutes after the test. The control group and the patients, who had no ST segment depression after dipyridamole, performed isometric contraction (handgrip) for 5 minutes and then the 12-lead electrocardiogram was recorded. All patients had coronary angiography. We also performed treadmill stress testing in 28 patients. Dipyridamole testing was positive (greater than or equal to 1 mm ST depression on electrocardiogram) in 7 of 22 patients with coronary arterial disease, of whom 6 had positive treadmill stress testing. Only 2 patients had previous myocardial infarction in the group with positive dipyridamole tests. Of the 15 in whom dipyridamole testing was negative, 5 had positive treadmill stress testing, while 13 of them had had previous myocardial infarction. All patients in the control group had negative dipyridamole stress testing and normal coronary angiograms. No additional ST segment changes were observed in the group who had performed isometric contraction test (both dipyridamole test negative and control groups). Sensitivity and specificity of the test were 32 and 100%, respectively. Comparison of collateral vessels between the groups positive and negative for dipyridamole revealed no difference. But the number of patients with old myocardial infarction was higher in those testing negative than in those who proved positive.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two patients with familial Mediterranean fever showed the classic features of pericardial involvement and one of them (Case 2) had pericardial effusion detected by echocardiography. These and previously published cases show that familial Mediterranean fever should be considered as a cause of pericarditis and/or pericardial effusion.

Abstract
As it is a rare case, we report a 37-year-old woman who had transmural myocardial infarction in her last trimester. Coronary arteriography done 15 days after her normal delivery showed normal coronary arteries and left ventriculography showed an apical aneurysm. The proposed cause appears to be coronary spasm.
