Abstract
BACKGROUND The number and proportion of elderly patients living with chronic hepatitis C are expected to increase in the coming years. We aimed to compare the real-world efficacy and safety of direct-acting antiviral treatment in elderly and younger Turkish adults infected with chronic hepatitis C. METHODS In this multicenter prospective study, 2629 eligible chronic hepatitis C patients treated with direct-acting antivirals between April 2017 and December 2019 from 37 Turkish referral centers were divided into 2 age groups: elderly (≥65 years) and younger adults (<65 years) and their safety was compared between 2 groups in evaluable population. Then, by matching the 2 age groups for demographics and pretreatment risk factors for a non-sustained virological response, a total of 1516 patients (758 in each group) and 1244 patients (622 in each group) from the modified evaluable population and per-protocol population were included in the efficacy analysis and the efficacy was compared between age groups. RESULTS The sustained virological response in the chronic hepatitis C patients was not affected by the age and the presence of cirrhosis both in the modified evaluable population and per-protocol population (P = .879, P = .508 for modified evaluable population and P = .058, P = .788 for per-protocol population, respectively). The results of the per-protocol analysis revealed that male gender, patients who had a prior history of hepatocellular carcinoma, patients infected with non-genotype 1 hepatitis C virus, and patients treated with sofosbuvir+ribavirin had a significantly lower sustained virological response 12 rates (P < .001, P = .047, P = .013, and P = .025, respectively). CONCLUSION Direct-acting antivirals can be safely used to treat Turkish elderly chronic hepatitis C patients with similar favorable efficacy and safety as that in younger adults.

Abstract
Background Epidemiology of nosocomial infections may show variability because of under-estimation of infection control measures (ICMs) in coronavirus disease 19 (COVID-19) outbreak. Aim To investigate the Acinetobacter bacteremia outbreak developed in an intensive care unit (ICU) between March 20 to May 15, 2020, examine the risk factors, and re-evaluate ICM retrospectively. Material and Methods A retrospective cohort analysis was conducted to determine the risk factors, pulsed field gel electrophoresis (PFGE) was performed for analysis of the outbreak, ICM practices were observed by a team, and infection control interventions were undertaken. Results Acinetobacter bacteremia developed in 17 patients (21.5%) within 79 COVID-19 patients included in the study. The mean age of the bacteremic patients was 67.3 (SD = 14.82) years, and 82.4% of them were male; of these, 15 died, leading to 88.2% mortality. The bacteremia rate was higher compared with a 14-month period preceding the COVID-19 pandemic (17/79 versus 12/580 patients, respectively). PFGE revealed that the outbreak was polyclonal. On multi-variate analysis, the bacteremia development rate was 13.7 and 5.06 times higher with central venous catheter (CVC) use and in patients with chronic obstructive pulmonary disease (COPD), respectively. The mortality rate was higher in bacteremic patients (p = 0.0016). It was observed that ICMs were not followed completely, especially change of gloves and hand hygiene. Contamination of A. baumannii was observed in 38% of the gloves. Conclusion COPD and CVC use were determined as risk factors for Acinetobacter bacteremia development, and failures in ICM may have led to cross-contamination of endemic A. baumannii. The outbreak could be controlled within 3 weeks of interventions.

Abstract
Background and Aim The aim of the present study was to examine the etiology of hepatocellular carcinoma (HCC) by underlying cause and determine the characteristics and clinical features of patients with HCC. Materials and Methods The study comprised 1802 HCC patients diagnosed and followed up by Liver Diseases Outpatient Clinics in 14 tertiary centers in Turkey between 2001 and 2020. Results The mean age was 62.3±10.7 years, and 78% of them were males. Of the patients, 82% had cirrhosis. Hepatitis B virus (HBV) infection was the most common etiology (54%), followed by hepatitis C virus (HCV) infection (19%) and nonalcoholic fatty liver disease (NAFLD) (10%). Of the patients, 56% had a single lesion. Macrovascular invasion and extrahepatic spread were present in 15% and 12% of the patients, respectively. The median serum alpha-fetoprotein level was 25.4 ng/mL. In total, 39% of the patients fulfilled the Milan Criteria. When we compared the characteristics of patients diagnosed before and after January 2016, the proportion of NAFLD-related HCC cases increased after 2016, from 6.6% to 13.4%. Conclusion Chronic HBV and HCV infections remain the main causes of HCC in Turkey. The importance of NAFLD as a cause of HCC is increasing.

Abstract
AIM In this study, we aimed to define the predictive role of liver function tests at admission to the hospital in outcomes of hospitalised patients with COVID-19. MATERIAL AND METHOD In this multicentric retrospective study, a total of 269 adult patients (≥18 years of age) with confirmed COVID-19 who were hospitalised for the treatment were enrolled. Demographic features, complete medical history and laboratory findings of the study participants at admission were obtained from the medical records. Patients were grouped regarding their intensive care unit (ICU) requirements during their hospitalisation periods. RESULTS Among all 269 participants, 106 were hospitalised in the ICU and 66 died. The patients hospitalised in ICU were older than patients hospitalised in wards (P = .001) and expired patients were older than alive patients (P = .001). Age, elevated serum D-dimer, creatinine and gamma-glutamyl transferase (GGT) levels at admission were independent factors predicting ICU hospitalisation and mortality in COVID-19 patients. CONCLUSION In conclusion, in hospitalised patients with COVID-19, laboratory data on admission, including serum, creatinine, GGT and d-dimer levels have an important predictive role for the ICU requirement and mortality. Since these tests are readily available in all hospitals and inexpensive, some predictive formulas may be calculated with these parameters at admission, to define the patients requiring intensive care.

Abstract
BACKGROUND Inflammation plays an important role in the development of cardiovascular disease, including atherosclerosis and arrhythmia. The aim of this study was to evaluate atrial conduction times (ACTs) in patients with inflammatory bowel disease (IBD) in which systemic chronic inflammation is evident. METHODS In this cross-sectional, prospective, single-center study, 79 IBD patients (51 ulcerative colitis; 28 Crohn's disease) and 70 healthy controls were included. Atrial electromechanical properties were measured by recording simultaneous surface electrocardiography (ECG) with transthoracic echocardiography (ECHO) and tissue Doppler imaging methods. The relationship between age, disease duration, and ACT was evaluated. RESULTS There were significantly increased conduction durations of lateral-PA (time interval from the onset of the P-wave on surface ECG to the beginning of the late diastolic wave), septal-PA, tricuspid-PA, and interatrial-electromechanical delay (IA-EMD), right intraatrial EMD, and left intraatrial (LI-EMD) durations in IBD patients (P < 0.001). In IBD patients, there was a positive correlation with age, lateral PA, septal PA, tricuspid PA, IA-EMD, and LI-EMD (P < 0.05). A positive correlation was found between disease duration and only lateral PA and tricuspid PA (P < 0.05). CONCLUSION In IBD patients, prolonged ACT consists a potential risk for severe atrial arrhythmias. ECG and ECHO screening can be useful in identifying risk groups in IBD patients and taking precautions for future cardiac complications.

Abstract
AIM Oral and dental heath are important aspects of general health and impact the quality of life and well-being. In this study, we aimed to assess the level of knowledge and attitudes towards oral and dental health and to examine the relative effect of social-behavioural risk factors on caries and other teeth problems among seventh and eighth grade students. METHODS Study Design: The study population consisted of all seventh and eighth graders who started the 2011 school year in Sarigol village of the Manisa city, Turkey (n = 377). Data were gathered by questionnaires which were carried out before tooth examination. Associations between sociodemographic characteristics, knowledge items, attitudinal factors and number of dental caries, dental fillings and teeth loss were studied. RESULTS Oral health was worse among females (p=0.002). As the number of children under care increased in the house, the number of dental filling and teeth loss increased in the students (p= 0.001 and p=0.021). Education of mothers of students who had worse dental health was significantly lower compared to the others (p=0.029). Among students who had four and more dental caries and dental fillings, frequency of dentist visit was lower (p= 0.034 and p= 0.005). Among students who had more dental caries, the knowledge that consumption of acidic beverages is not good for oral health was less prevalent (p=0.011). STATISTICS Associations between sociodemographic characteristics, knowledge items, attitudinal factors and number of dental caries, dental fillings and teeth loss were studied using chi-square test. CONCLUSIONS Health authorities should strengthen the implementation of oral disease prevention and oral health promotion programs rather than traditional curative care. Community-oriented education programs for students and their families are crucial for this purpose.

Abstract
Background and aim The aim of this study is to evaluate whether the long-term (≥4 weeks) use of proton pump inhibitors (PPIs) is a risk factor for intubation requirement and mortality in patients hospitalized for COVID-19. Materials and methods In this multicentric retrospective study, a total of 382 adult patients (≥18 years of age) with confirmed COVID-19 who were hospitalized for treatment were enrolled. The patients were divided into two groups according to the periods during which they used PPIs: the first group included patients who were not on PPI treatment, and the second group included those who have used PPIs for more than 4 weeks Results The study participants were grouped according to their PPI usage history over the last 6 months. In total, 291 patients did not use any type of PPI over the last 6 months, and 91 patients used PPIs for more than 4 weeks. Older age (HR: 1.047, 95% CI: 1.026–1.068), current smoking (HR: 2.590, 95% CI: 1.334–5.025), and PPI therapy for more than 4 weeks (HR: 1.83, 95% CI: 1.06–2.41) were found to be independent risk factors for mortality Conclusion The results obtained in this study show that using PPIs for more than 4 weeks is associated with negative outcomes for patients with COVID-19. Patients receiving PPI therapy should be evaluated more carefully if they are hospitalized for COVID-19 treatment.

Abstract
BACKGROUND It is controversial whether entecavir or tenofovir differs in reducing hepatocellular carcinoma (HCC) risk. We aimed to compare the efficacy of entecavir and tenofovir in reducing HCC risk in chronic hepatitis B (CHB) patients. METHODS This retrospective study included 607 nucleos(t)ide naive CHB patients who had received entecavir or tenofovir. Patients who developed HCC during the first 12 months of therapy were excluded. Cumulative HCC incidences at years 2, 3, 4, 5 and 10 were compared between entecavir and tenofovir groups. Factors associated with HCC were determined by univariate and multivariate analyses. RESULTS Nineteen (3.1%) patients developed HCC, 12 (4.8%) in entecavir group and 7 (1.9%) in tenofovir group (P = .045). In the entire cohort, cumulative HCC incidences at years 2, 3, 4, 5 and 10 were 1.8%, 2.9%, 4.4%, 5.2% and 9.9% in entecavir group, and 0.6%, 2.4%, 2.4%, 2.4% and 3.7% in tenofovir group, respectively (log-rank P = .130). In multivariate analysis, age ≥50 years, cirrhosis, decompensated cirrhosis, high GGT and low platelet levels were associated with HCC in the entire cohort. In advanced fibrosis/cirrhosis cohort, cumulative HCC incidences at years 2, 3, 4, 5 and 10 were 4.6%, 7.1%, 8.6%, 12.1% and 15.5% in entecavir group, and 1.8%, 5.6%, 5.6%, 5.6% and 8.5% in tenofovir group, respectively (log-rank P = .267). In multivariate analysis, age ≥50 years, decompensated cirrhosis, high GGT and low platelet levels were associated with HCC in the advanced fibrosis/cirrhosis cohort. CONCLUSION Entecavir and tenofovir are similarly effective in reducing HCC risk in CHB patients.

Abstract
BACKGROUND AND AIMS Chronic viral hepatitis (CVH) has a spectrum from asymptomatic disease to cirrhosis and hepatocellular carcinoma. In our study, we aimed to establish the relations between disease stage, illness perception, coping strategies and psychological morbidity in CVH. METHODS A total of 182 patients with chronic hepatitis B (CHB) (n = 136) and chronic hepatitis C (CHC) (n = 46) were enrolled. Illness perceptions were measured with the Brief Illness Perceptions Questionnaire. Coping strategies were measured with the Carver Brief Coping Questionnaire. Anxiety and depression were measured with the Hospital Anxiety and Depression Scale. Relations were evaluated by structural equation modeling (SEM). RESULTS In CHB, combining the questionnaire data using SEM resulted in a final model with an excellent fit [χ2 (2) = 0.00, P = 1.000, χ2/N = 0.00, root mean square error of approximation (RMSEA) < 0.001, comparative fit index (CFI) = 1.000, goodness-of-fit index (GFI) = 1.000]. Disease stage had a significant direct influence on illness perceptions (β = 0.23, P = 0.006). Illness perceptions had a significant direct influence on emotional coping strategy, depression and anxiety (β = 0.20, P = 0.019; β = 0.33, P < 0.001; β = 0.59, P < 0.001, respectively). While the use of emotional coping strategies was associated significantly (P = 0.01) with the presence of anxiety, problem-focused coping strategy was associated with depression (P = 0.004). In CHC, SEM resulted in a final model with an excellent fit [χ2 (2) = 0.078, P = 0.962, χ2/N = 0.039, RMSEA<0.001, CFI = 1.000, GFI = 0.999]. Disease stage did not have a significant direct influence on illness perceptions (P > 0.05). Illness perceptions had a significant direct influence on depression and anxiety (β = 0.27, P = 0.023; β = 0.44, P < 0.001, respectively). CONCLUSION The psychological consequences of the disease vary depending on the person's perception of illness and coping strategies.

Abstract
The HCC-RESCUE score was developed to predict hepatocellular carcinoma (HCC) risk in Korean chronic hepatitis B (CHB) patients under entecavir therapy. We aimed to validate the HCC-RESCUE score to predict HCC risk in Caucasian CHB patients under entecavir or tenofovir therapy and to compare the predictive performance of the HCC-RESCUE score with those of the CAMD, PAGE-B and modified PAGE-B (mPAGE-B) scores. The study included 647 nucleos(t)ide analogue-naive noncirrhotic and compensated/decompensated cirrhotic patients who had received entecavir or tenofovir for ≥6 months and did not develop HCC during the first 6 months of therapy. Patients with HCC-RESCUE scores ≤64, 65-84 and ≥85 points were classified into low-, intermediate- and high-risk groups, respectively. The AUROCs of the HCC-RESCUE, CAMD, PAGE-B and mPAGE-B scores to predict HCC risk at 5 years were 0.875, 0.870, 0.866 and 0.880, and those at 10 years were 0.862, 0.845, 0.841 and 0.862, respectively (both p > .05). Cumulative HCC incidences at 5 years were 0.0%, 10.5% and 15.8%, and those at 10 years were 1.4%, 15.5% and 24.9%, respectively, in the low-, intermediate- and high-risk groups based on the HCC-RESCUE score (both log rank p < .001). In the entecavir versus tenofovir cohorts, the AUROCs of the HCC-RESCUE score to predict HCC risk at 5 and 10 years were 0.831 versus 0.898 and 0.803 versus 0.910, respectively (both p > .05). The HCC-RESCUE score accurately predicted HCC risk in Caucasian CHB patients under entecavir or tenofovir therapy. A substantial proportion of patients can be dropped from HCC surveillance by using the HCC-RESCUE score.

Abstract
BACKGROUND AND AIM this study aimed to compare carotid intima media (CIMT) and epicardial adipose tissue (EAT) measurements, which are considered as markers for the detection of early atherosclerosis in healthy controls and inflammatory bowel disease (IBD) cases. METHODS a total of 60 IBD patients (25 Crohn's disease and 35 ulcerative colitis) and 60 healthy patients (as a control group) were included in the study. The measurements of CIMT and EAT were performed using echocardiography and ultrasonography, respectively. Statistical analysis was used to determine the relationship between the parameters. RESULTS the thickness of bilateral (right and left) CIMT and EAT were significantly higher in IBD than in the control group (p < 0.05). There was a positive correlation between EAT and bilateral (right and left) CIMT in IBD patients (p < 0.05). CONCLUSION IBD is associated with an increased thickness of EAT and CIMT. Chronic inflammation in IBD may increase the risk of atherosclerotic heart disease. Thus, only measuring the thickness of EAT and CIMT can be used as an objective, easy, simple, affordable, non-invasive and accessible assessment method in order to screen for this risk.

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
BACKGROUND/AIMS There are only a few epidemiological study about inflammatory bowel disease in the last 10 years in Turkey, especially in Western Blacksea region. In our study, we aimed to identify the changes in the incidence and the prevalence of inflammatory bowel disease in Western Blacksea region at the last 10 years. METHODS Totally 223 patients with inf lammatory bowel disease (160 ulcerative colitis, 63 Crohn's disease) were enrolled in the study followed up between 2004 to 2013 years. The epidemiological characteristics of patients were recorded. RESULTS The prevalences were 12.53/105 and 31.83/105 for Crohn's disease and ulcerative colitis respectively. Mean annual incidences increased from 0.99/105 and 0.45/105 for ulcerative colitis and Crohn's disease (2004 to 2005 years) to 4.87/105 and 2.09/105 for ulcerative colitis and Crohn's disease respectively (2011 to 2013 years). While the prevalence was higher in urban areas in Crohn's disease (12.60/105 ), it was higher in rural areas in ulcerative colitis (36.17/105 ). In ulcerative colitis, mean annual incidences were 2.91/105 and 2.86/105 for urban and rural areas respectively. In Crohn's disease, they were 1.37/105 and 1.08/105 for urban and rural areas respectively. CONCLUSION The incidence of inflammatory bowel disease seems to increase in Western Blacksea region at the last 10 years. This increment is more prevalent in rural areas.

Abstract
BACKGROUND/AIMS Inflammatory bowel diseases are chronic, relapsing, inflammatory conditions. They have a genetic backround resulting in patient susceptibility. The aim of our study is to investigate the involvement of IL23R, JAK2, and STAT3 polymorphisms in inflammatory bowel diseases in a Turkish population. MATERIALS AND METHODS Polymorphisms in IL23R (rs11209026), JAK2 (rs10758669), and STAT3 (rs3816769, rs2293152, rs744166, rs957970, rs8074524) were genotyped in 69 Crohn's disease patients, 157 ulcerative colitis patients, and 89 healthy controls. RESULTS The presence of (C) in rs10758669, (T) and (TT) in rs957970, and (TT) in rs744166 were found to increase the susceptibility to Crohn's disease (p=0.049, p=0.016, p=0.010, p=0.035, respectively), while rs2293152 (GC), rs744166 (CT), and rs957970 (CT) provide protection against Crohn's disease (p=0.007, p=0.043, p=0.043, respectively). While rs2293152 (GC) was protective, rs2293152 (CC) increased the susceptibility to ulcerative colitis (p=0.009, p=0.001). All the polymorphisms were associated with age-at-diagnosis, except rs11209026. Furthermore, rs2293152 was associated with an extension in ulcerative colitis, while rs10758669, rs3816769, rs744166, rs2293152, and rs957970 were associated with the subphenotype in Crohn's disease. The presence of rs10758669 (AC) was protective against perianal Crohn's disease (p=0.016). Additionally, rs10758669 and rs2293152 in Crohn's disease and rs8074524, rs3816769, and rs10758669 in ulcerative colitis were associated with the requirement of immunsuppression. Finally, rs8074524 and rs10758669 in Crohn's disease and rs11209026 in ulcerative colitis were associated with disease-related operation. CONCLUSION This is the first study of the single marker association of IL23R, JAK2, and STAT3 polymorphisms with ulcerative colitis and Crohn's disease in a Turkish population. It was demonstrated that these polymorphisms may be effective in the etiology of inflammatory bowel disease in this Turkish population.

Abstract
BACKGROUND AND OBJECTIVE Ulcerative colitis is an inflammatory condition of the colon in the gastrointestinal system. Currently, the most potent medications used for ulcerative colitis produce no response in 20-30% of cases. There is a need for more efficient and reliable medications. Tyrosine kinase inhibitors have shown efficacy in some inflammatory diseases. Although dasatinib, a tyrosine kinase inhibitor, suppresses proinflammatory cytokines in colonic tissue, there are a few cases of hemorrhagic colitis with dasatinib. There is no study investigating the effect of dasatinib on experimental colitis. We aimed to investigate the effect of dasatinib in a colitis model induced with acetic acid in our study. METHODS In the study, 24 male Sprague-Dawley rats randomly distributed into 4 groups of 6 rats each as control, dasatinib, colitis and dasatinib+colitis groups. For colitis induction, 4% acetic acid was used. Sacrificing of the rats was performed on the seventh day. Disease activity, morphologic and histological injury, superoxide dismutase, myeloperoxidase and malondialdehyde activity, TNFα and CD3 expression were assessed in colonic tissue. RESULTS Apart from malondialdehyde, significant difference in all parameters between the control and colitis groups was determined. Difference between the colitis and colitis+dasatinib groups was not significant in only weight loss and biochemical parameters. Though dasatinib does not fully resolve the changes in colitis, there was significant regression. CONCLUSIONS Dasatinib decreased the inflammation in a rodent model of colitis. It may be provide this effect by the suppression of TNFα. Dasatinib may be one of the treatment options for ulcerative colitis.

Abstract
AIM The aim was to develop a high-performance computer-aided diagnosis (CAD) system with image processing and pattern recognition in diagnosing pancreatic cancer by using endosonography images. MATERIALS AND METHODS On the images, regions of interest (ROI) of three groups of patients (<40, 40-60 and >60) were extracted by experts; features were obtained from images using three different techniques and were trained separately for each age group with an Artificial Neural Network (ANN) to diagnose cancer. The study was conducted on endosonography images of 202 patients with pancreatic cancer and 130 noncancer patients. RESULTS 122 features were identified from the 332 endosonography images obtained in the study, and the 20 most appropriate features were selected by using the relief method. Images classified under three age groups (in years; <40, 40-60 and >60) were tested via 200 random tests and the following ratios were obtained in the classification: accuracy: 92%, 88.5%, and 91.7%, respectively; sensitivity: 87.5%, 85.7%, and 93.3%, respectively; and specificity: 94.1%, 91.7%, and 88.9%, respectively. When all the age groups were assessed together, the following values were obtained: accuracy: 87.5%, sensitivity: 83.3%, and specificity: 93.3%. CONCLUSIONS It was observed that the CAD system developed in the study performed better in diagnosing pancreatic cancer images based on classification by patient age compared to diagnosis without classification. Therefore, it is imperative to take patient age into consideration to ensure higher performance.

Abstract
AIM Few data are available regarding the effects of interleukin 28B (IL28B) polymorphisms in chronic hepatitis D (CHD) patients. This study investigated the relationship between IL28B poly-morphisms and the response of patients with CHD infections to pegylated interferon (PEG-IFN) therapy. MATERIALS AND METHODS A total of 101 CHD patients were -selected, 80 of whom (46 males ; median age 41 years) satisfied the inclusion criteria and were enrolled in the study. Thirty-seven patients were treated with peg-IFNα for at least 12 months and were followed for a median of 18 months (range, 12-30 months). The primary treatment endpoint was the suppression of HDV replication, as documented by the loss of detectable HDV RNA in serum. Genotyping was used to analyse the IL28B polymorphisms rs12979860 and rs8099917 according to the virological response. RESULTS After treatment, a sustained viral response (SVR) was achieved in 19 (51%) of the patients treated with PEG-INF. The IL28B genotypes in the 80 patients were as follows : CC in 36 (45%), CT in 33 (41%) and TT in 11 (14%) for rs12979860, and GG in 4 (5%), GT in 27 (34%) and TT in 49 (61%) for rs8099917. SVR was achieved in 5 (26%), 10 (53%) and 4 (21%) patients with CC, CT and TT at rs12979860, respectively, and one (5%), nine (47%) and nine (47%) patients with GG, GT and TT at rs8099917, respectively. There were differences in the SVR among genotypes (rs12979860 and rs8099917 ; chi-squared test, p = 0.047). CONCLUSION IL28B predicts the PEG-IFN response in patients with CHD infection.

Abstract
BACKGROUND AND AIMS Inflammatory bowel disease is a chronic inflammatory disease of the gastrointestinal system. In some cases, current medications used for inflammatory bowel disease may not be enough for remission, creating a need for more potent and reliable medications. There is no study showing the efficacy of fostamatinib, with proven effects on some inflammatory diseases, on ulcerative colitis. In our study we planned to research the efficacy of fostamatinib, a spleen tyrosine kinase inhibitor, on acetic acid-induced colitis. METHODS The study included 28 male Sprague-Dawley rats, randomly divided into control group, fostamatinib group, colitis group and fostamatinib + colitis group, each containing seven rats. Colitis induction was performed with 4% acetic acid. Colonic inflammation was assessed with disease activity index, macroscopic and histological damage scores, colonic myeloperoxidase, malondialdehyde and superoxide dismutase activity, and tumour necrosis factor alpha [TNFα], CD3, Syk, and phospho-Syk expression. RESULTS There was a significant difference between the colitis and control groups in terms of all parameters. The disease activity index, macroscopic and microscopic damage scores, immunohistochemical TNFα, CD3, Syk, and phospho-Syk expression, and tissue myeloperoxidase activity were found to be significantly lower in the colitis + fostamatinib group compared with the colitis group. There was no significant difference between the two groups in terms of myeloperoxidase and malondialdehyde activity. CONCLUSIONS Fostamatinib reduced the inflammatory damage in the experimental colitis. This effect may be due to suppression of TNFα, T-lymphocytes, and neutrophils in colonic mucosa via suppression of Syk. Fostamatinib may be an appropriate treatment alternative for ulcerative colitis. Further clinical studies are required to support this.

Abstract
BACKGROUND/AIM To investigate the efficacy of diffusion-weighted magnetic resonance imaging (DWI) in the diagnosis and staging of fibrosis induced by experimental bile duct ligation (BDL). MATERIALS AND METHODS Twenty-four rats were divided randomly into four groups: control, BDL--3 days, BDL--2 weeks, and BDL--4 weeks. DWI was performed with b-values of 100 and 500 on the rats from control group at day zero, on the rats from the BDL--3 days group at the end of day 3, on the rats from the BDL--2 weeks group at the end of day 14, and on the rats from the BDL--4 weeks at the end of day 28. RESULTS When fibrosis scores generated in all groups were evaluated together, a strong negative correlation was detected between fibrosis scores and apparent diffusion coefficient (ADC) values measured using b 100 and b 500. ADC values obtained using b 100 were found to be significantly higher compared to the fibrosis observed in both the BDL--2 weeks and BDL--4 weeks groups (P < 0.003 and P < 0.001, respectively). CONCLUSION We think that DWI may be an alternative to liver biopsy for the diagnosis and staging of hepatic fibrosis with underlying extrahepatic cholestasis.

Abstract
BACKGROUND The effect of hepatitis B virus (HBV) infection on fatty liver disease is unclear. OBJECTIVES The aim of this study was to investigate the viral and host causes of fatty liver in chronic hepatitis B (CHB) patients. This study included 88 CHB patients of which 17 were not treated. Liver biopsy was performed in each patient. Group 1 included those with hepatic steatosis (n=28) and group 2 those without hepatic steatosis. The groups were compared in terms of age, body mass index (BMI), Homeostasis Model Assessment- Insulin Resistance (HOMA-IR), viral load, biochemical parameters and histological findings. Patients in group 1 were subdivided according to the degree of steatosis as follows: grade 1 (15 patients, 53.6%), grade 2 (6 patients, 21.4%), and grade 3 (7 patients, 25%). RESULTS In group 1 (n=28), mean age, BMI, cholesterol, and HOMA-IR were found to be significantly higher than in group 2 (n=60). There were no significant differences in the positivity of viral load, HbeAg, treatment, fibrosis and other laboratory parameters between the two groups. HOMA-IR was the only independent predictive factor of liver steatosis in patients with CHB in logistic regression analysis. CONCLUSION Hepatic steatosis in CHB patients was associated with host metabolic factors.

Abstract
BACKGROUND AND OBJECTIVE Inflammatory bowel disease is a group of chronic inflammatory conditions affecting gastrointestinal tract. Lots of genes have been identified resulting in susceptibility to inflammatory bowel disease. Any polymorphism leading to functional modifications in tyrosine kinase-2 may precipitate excessive immune response in the intestinal mucosa. The aim of our study is to investigate the involvement of tyrosine kinase-2 polymorphisms in the patients with inflammatory bowel disease in Turkish population. METHODS Four single nucleotide polymorphisms in tyrosine kinase-2 (rs280523, rs2304256, rs280519 and rs280496) were genotyped in 60 Crohn's disease, 151 ulcerative colitis patients and 89 unrelated healthy controls. These polymorphisms were detected by real-time polymerase chain reaction. RESULTS The presence of genotype (CC) in rs2304256 and (AA) in rs280519 were found to increase the susceptibility to ulcerative colitis (P=0.024, 0.025, respectively). rs2304256 (CA) and rs280519 (AG) have provided protection against ulcerative colitis (P=0.021, 0.012, respectively). rs280519 (AG) was protective against Crohn's disease (P=0.045). rs2304256 (CC) increased the susceptibility to inflammatory Crohn's disease (P=0.014). The presence of rs2304256 (A) increased the susceptibility to perianal Crohn's disease (P=0.03). Both rs280519 and rs2304256 polymorphisms were associated with the requirement of corticosteroid and immunosuppressive therapy in ulcerative colitis. CONCLUSION This study is the first demonstration of the single marker association of tyrosine kinase-2 polymorphisms with ulcerative colitis and Crohn's disease in Turkish population. They may be effective in the etiology of inflammatory bowel disease in our population. Disparity between our study and others may be related to ethnic differences.

Abstract
BACKGROUND AND AIM Iatrogenic perforation of the gut during endoscopy remains an uncommon but critical complication with significant morbidity and probable mortality than usual surgical treatment. Some authors have adopted a non-surgical closure method in chosen cases and, since 1993, endoclips have been used to close perforation in the stomach. The endoscopic practice of endoclips has been commonly used in the gut for hemostasis. Currently, the use of endoscopic techniques is increasing for the closure of endoscopic submucosal dissection or endoscopic mucosal resection. Endoscopic perforations that improved with endoscopic closure in the literature prior to 2008 have been previously described. In the present article, we present a descriptive review of cases with iatrogenic perforation in the gut treated with endoclips between 2008 and 2014. METHODS Comprehensive literature screening and a systematic review using PubMed and Medline was done for all reports published between January 2008 and December 2014 using the endoclip technique in the closure of iatrogenic perforations. RESULTS A total of 47 studies published between 2008 and 2014 using endoclips for the closure of iatrogenic perforations of the gut (nine esophagus, 11 stomach, 15 duodenum, 12 colon and rectum) were found. All studies were explained briefly and summarized in a table. CONCLUSIONS There is strong evidence to show the efficacy of endoclips in the management of iatrogenic perforations, especially when recognized early. Limitations of endoclipping such as inefficiency against large perforations may be overcome by improving novel techniques in the future.

Abstract
OBJECTIVES The pathogenesis of fibrosis in scleroderma (SSc) is unknown. TGF-β and platelet-derived growth factor are important in the development of fibrosis and tyrosine kinases are involved in these pathways. The possible antifibrotic effects of various kinase inhibitors in SSc have been studied before. Spleen tyro-sine kinase (Syk) is a protein tyrosine kinase which activates intracellular signal transduction pathways; and has been claimed to be involved in the pathogenesis of systemic autoimmune diseases. Inhibition of Syk suppresses IgE- and IgG-associated FcR signal activation in various cell types; and suppresses experimental arthritis and skin and kidney disease in lupus-prone mice. We investigated the ability of a small drug, the Syk inhibitor, fostamatinib, to protect mice from bleomycin-induced SSc. METHODS Four study groups of BALB/c mice were included into this study: control, bleomycin (administered subcutaneously to BALB/c mice for 21 days), bleomycin and fostamatinib (mice fed with chow containing a Syk inhibitor for 21 days), and fostamatinib alone groups. Skin and lung tissue specimens were obtained and evaluated histologically. RESULTS Treatment with fostamatinib significantly reduced skin thickness and fibrosis. Mice treated with fostamatinib also displayed less fibrosis and inflammation in the lung tissue. Following fostamatinib treatment, Syk, phospho-Syk, and TGF-β expression decreased in both skin and lung tissues. CONCLUSIONS The Syk inhibitor fostamatinib prevented bleomycin-induced fibrosis and inflammation in the skin and in the lung. The anti-fibrotic effect of fostamatinib is linked to reduced Syk phosphorylation and TGF-β expression. The Syk pathway appears as a potential molecular target for therapeutic intervention in SSc.

Abstract
BACKGROUND/AIMS Inflammatory bowel disease, a chronic inflammatory disease with unknown etiology, affects the small and large bowel at different levels. It is increasingly considered that innate immune system may have a central position in the pathogenesis of the disease. As a part of the innate immune system, bactericidal permeability increasing protein has an important role in the recognition and neutralization of gram-negative bacteria. The aim of our study was to investigate the involvement of bactericidal permeability increasing protein gene polymorphism (bactericidal permeability increasing protein Lys216Glu) in inflammatory bowel disease in a large group of Turkish patients. PATIENTS AND METHODS The present study included 528 inflammatory bowel disease patients, 224 with Crohn's disease and 304 with ulcerative colitis, and 339 healthy controls. RESULTS Bactericidal permeability increasing protein Lys216Glu polymorphism was found to be associated with both Crohn's disease and ulcerative colitis (P = 0.0001). The frequency of the Glu/Glu genotype was significantly lower in patients using steroids and in those with steroid dependence (P = 0.012, OR, 0.80; 95% confidence interval [CI]: 0.68-0.94; P = 0.0286, OR, 0.75; 95% CI: 0.66-0.86, respectively). There was no other association between bactericidal permeability increasing protein gene polymorphism and phenotypes of inflammatory bowel disease. CONCLUSIONS Bactericidal permeability increasing protein Lys216Glu polymorphism is associated with both Crohn's disease and ulcerative colitis. This is the first study reporting the association of bactericidal permeability increasing protein gene polymorphism with steroid use and dependence in Crohn's disease.

Abstract
AIM Neutrophil-lymphocyte ratio (NLR) has been used as a simple, affordable, and easily accessible marker to predict prognosis in a variety of inflammatory and neoplastic diseases. However, there are few studies investigating their role in patients with hepatitis B. The aim of this study was to investigate the relationship between NLR and liver fibrosis in patients who were being followed as inactive hepatitis B carriers. MATERIALS AND METHODS The study included 78 patients who were followed for 1 year as inactive hepatitis B carriers. Liver biopsy was performed and the fibrosis scores of the histological activity index were assessed according to the Metavir scoring system. The patients were divided into two groups on the basis of the fibrosis scores: those with a score below 2 and those with a score above 2. In both groups, demographic data such as sex, age, and BMI were similar. The NLR of patients was calculated from blood samples taken at the same time as the biopsy. RESULTS Histopathologic analysis of 78 patients showed that 41 (53%) had fibrosis grade 0-1 and 37 (47%) patients had fibrosis grade greater than 2. According to the biopsy results, there were no cirrhotic patients. NLR was found to be statistically significantly lower in the group with fibrosis grade of at least 2 (1.51±0.61 vs. 1.79±0.64, P=0.043). Other biochemical and hematological data were found to be similar in both groups. No correlation was found between laboratory values and NLR. In addition, there was no correlation between NLR with histologic activity. Spearman correlation analysis showed a negative correlation between the fibrosis score and NLR (r=-0.279, P=0.013). CONCLUSION In inactive hepatitis B carriers, the histological activity index and NLR were found to be correlated negatively. NLR can be used as a predictor of fibrosis in combination with other noninvasive markers.

Abstract
OBJECTIVE We determined whether U-shaped relationships exist between serum lipoprotein[Lp](a) and cardiometabolic risk. METHODS In population-based nondiabetic and diabetic middle-aged adults (n=1 428 and 241, respectively) who had been genotyped for the LPA rs10455872 A>G polymorphism, we adjusted the Lp(a) concentration for the effects of genotype and other covariates. Via sex-specific equations we estimated expected Lp(a) concentration in each participant, and the quotient between observed to expected Lp(a) values was determined. Lp(a) and Lp(a) quotient tertiles served to identify non-linear associations with outcomes. RESULTS Incident 81 cases of diabetes and 128 of coronary heart disease (CHD) developed at 5.1 years' follow-up. Lp(a) concentration was linearly associated with the LPA genotype, gender, total cholesterol, (inversely) fasting insulin, which together with age formed the variables to derive the equations. In logistic regression for incident diabetes, the low Lp(a) quotient tertile was a predictor (RR 1.95 [95%CI 1.10; 3.47]) alike the low Lp(a) tertile, additively to major confounders. Cox regression models comprising sex, age, LPA genotype, smoking status, systolic pressure and serum HDL-cholesterol disclosed that, compared with the mid-tertile, both low (HR 1.77) and high Lp(a) quotient tertiles significantly predicted incident CHD, especially in women. CONCLUSION Elevated cardiometabolic risk is conferred by apparently reduced circulating Lp(a) assays supporting the notion that "low" serum Lp(a), mediating autoimmune activation, is a major determinant of cardiometabolic risk.

Abstract
Saccharomyces boulardii is a probiotic used for the prevention of antibiotic-associated diarrhoea. We aimed to investigate whether S. boulardii could alter the effects of clarithromycin (CLA) and methotrexate (MTX) on oro-caecal intestinal transit and oxidative damage in rats. Rats were divided into two groups receiving a single dose of MTX (20 mg/kg) or CLA (20 mg/kg per d) for 1 week. Groups were treated with either saline or S. boulardii (500 mg/kg) twice per d throughout the experiment. The control group was administered only saline. Following decapitation, intestinal transit and inflammation markers of glutathione (GSH), malondialdehyde and myeloperoxidase were measured in intestinal and hepatic tissues. CLA and MTX increased intestinal transit, while S. boulardii treatment slowed down CLA-facilitated transit back to control level. Both MTX and CLA increased lipid peroxidation while depleting the antioxidant GSH content in the hepatic and ileal tissues. Conversely, lipid peroxidation was depressed and GSH levels were increased in the ileal and hepatic tissues of S. boulardii-treated rats. Increased ileal neutrophil infiltration due to MTX and CLA treatments was also reduced by S. boulardii treatment. Histological analysis supported that S. boulardii protected intestinal tissues against the inflammatory effects of both agents. These findings suggest that S. boulardii ameliorates intestinal injury and the accompanying hepatic inflammation by supporting the antioxidant state of the tissues and by inhibiting the recruitment of neutrophils. Moreover, a preventive effect on MTXinduced toxicity is a novel finding of S. boulardii, proposing it as an adjunct to chemotherapy regimens.

Abstract
BACKGROUND AND AIM An algorithm is needed for predicting coronary heart disease (CHD) risk in Turkish adults who have a high prevalence of metabolic syndrome (MetS). METHODS AND RESULTS Ten-year risk of CHD was estimated in 2232 middle-aged adults free of CHD at baseline, followed over 7.6-years. Cox proportional hazard regression was used to predict CHD. Discrimination was assessed with area under receiver operating characteristics curve (AROC). CHD developed in 302 subjects. In multivariable analysis, high-density lipoprotein (HDL)-cholesterol levels were borderline predictive in men; smoking status and HDL-and low-density lipoprotein (LDL)-cholesterol levels were not predictive in women. Age, presence of diabetes, systolic blood pressure and C-reactive protein (CRP) were predictors in both sexes, while smoking status and LDL-cholesterol were so in men only. AROC of the model was 0.789 in men, and 0.806 in women (p < 0.001 each). An algorithm using the stated seven variables was derived separately for each sex. After age adjustment, men and women in the highest quintile of risk score were significantly and 20-27-fold more likely to develop CHD than those in the lowest quintile. CONCLUSIONS In a population with prevalent MetS, low-grade inflammation is independently relevant for CHD, as are serum lipoproteins and smoking status. The derived algorithm is effective in estimating CHD risk among Turkish adults.

Abstract
BACKGROUND AND AIM An algorithm for predicting Type 2 diabetes (DM) risk in a population with prevalent metabolic syndrome (MetS) is needed since ethnicity influences the pathogenesis of DM. MATERIAL AND METHODS The 8- yr risk of DM was estimated in 2261 middle-aged Turkish adults free of DM at baseline who were followed for over 7.6 yr. DM newly developed in 212 subjects. Cox proportional hazard regression and 15 variables were used to predict DM. Discrimination was assessed with area under receiver operating characteristics curve (AROC). RESULTS In multivariable analysis, height, family income brackets, systolic blood pressure, smoking status, alcohol usage, and HDL-cholesterol levels were not predictive in either sex. In addition to sex, family history of DM, fasting glucose, and waist circumference were predictors, in men, age and non-HDL-cholesterol, while in women physical inactivity and serum C-reactive protein were so. AROC of the final model was 0.783 in men, 0.772 in women (p<0.001 each). An algorithm using the stated 7 variables was developed separately for each sex. Men and women in the top quintile of risk score were, respectively, 20 and 50 times and significantly more likely to develop DM than those in the bottom quintile. The predictive value of the algorithm was validated in 2 split samples. CONCLUSIONS A marker of low grade inflammation provides useful predictive ability beyond other simple predictors in a female population with MetS prevailing. The derived simple algorithm may be useful in estimating the 8-yr risk of DM among middle-aged Turkish men and women.

Abstract
PURPOSE recently, molecular subclassification of breast carcinomas has been proposed as a new prognostic parameter. METHODS we classified 222 invasive breast carcinoma cases in 5 molecular subtypes by using tissue microarray (TMA) and immunohistochemistry methods. These subtypes were luminal A (estrogen receptor/ER and/or progesterone receptor/ PR positive), luminal B (ER and/or PR positive + HER2 positive), HER2-expressing type (ER and PR negative, HER2 positive), basal-like type (ER, PR and HER2 negative, positive with at least one of these myoepithelial markers: CK5/6, CK14, EGFR) and null type (ER, PR, HER2 and myoepithelial markers negative). We compared these subtypes according to their clinicopathological features and GATA3 expression. RESULTS luminal A was the most frequent subtype. According to overall survival rates, HER2-expressing and basal- like types had the worst prognosis, while luminal A had the best. However, luminal B had the worst prognosis according to disease free survival. Most of the squamous differentiated metaplastic carcinomas were basal-like type. Tubular and mucinous carcinomas were luminal A. Most basal-like tumors were grade III. The majority of grade I tumors were luminal A. GATA3 positivity was associated with low grade tumors and luminal A subtype. CONCLUSION molecular classification can be accepted as an independent prognostic factor for invasive breast carcinomas. GATA3 expression was associated with luminal A and low histological grade. However, it wasn't shown as an independent parameter.

Abstract
AIMS We studied determinants of serum apolipoprotein C-III (apoC-III) and whether levels of apoC-III or its fractions predict metabolic syndrome (MetS), Type 2 diabetes and coronary heart disease (CHD). METHODS The predictive value of apoC-III, measured by immunoturbimetric immunoassay in 802 tracked individuals of a Turkish general population in determining cardiometabolic risk was assessed over 4.4 +/- 1.2 years' follow-up. Patients with MetS, Type 2 diabetes and CHD at baseline were excluded. RESULTS Total apoC-III, as well as both fractions, was significantly, linearly and inversely related to smoking status, positively to alcohol usage and to levels of complement C3. Mid and high tertiles of total or non-high density lipoprotein (HDL) apoC-III predicted significantly and independently incident MetS; they predicted CHD with risk ratios of 1.6 [95% confidence intervals (CI) 1.02-2.5], for 1 sd increment, after adjustments that included HDL cholesterol and body mass index (BMI). The highest tertile of HDL apoC-III was a major independent predictor of new-onset diabetes with a 2.5-fold risk ratio for 1 sd increment (95% CI 1.5-4.0) in combined sexes, after adjustment for waist circumference, HDL cholesterol and other confounders and was a better predictor than waist girth. CONCLUSIONS Serum total apoC-III or its fractions are linearly and inversely associated with smoking, positively with alcohol usage and serum complement C3. The presumably dysfunctional HDL apoC-III is a stronger predictor of Type 2 diabetes than waist girth in Turks. Non-HDL apoC-III predicts strongly the development of MetS as well as incident CHD, independent of HDL cholesterol, BMI and non-lipid factors. The atherogenicity of apoC-III and dysfunctionality of HDL apoC-III carry huge public health implications in Turks.

Abstract
BACKGROUND Predictive value of apolipoprotein (apo) A-I for incident hypertension, metabolic syndrome (MetS), type 2 diabetes (DM) and coronary heart disease (CHD) needs further exploration. METHODS A representative sample of Turkish adults was studied with this purpose prospectively. Sex-specific apoA-I tertiles were examined regarding cardiometabolic risk. RESULTS AND CONCLUSIONS A total of 1044 men and 1067 women (aged 49+/-12 years at baseline) were followed up over 7.4 years. High serum apoA-I levels were significantly associated in multivariable analysis with female sex, aging, alcohol intake, (inversely) cigarette smoking and, in women, with systolic blood pressure. Risk of diabetes was predicted in logistic regression in both genders by top versus bottom apoA-I tertile (RR 1.98; [95%CI 1.31; 3.0]), additive to age, body mass index (BMI), C-reactive protein (CRP), HDL-cholesterol and lipid lowering drugs. By adding sex hormone-binding globulin to the model in a subset of the sample, the association between high apoA-I and incident diabetes was attenuated only in women. ApoA-I tertiles tended to be positively associated also with hypertension and CHD only in women but this did not reach significance. High compared with low serum apoA-I levels nearly double the risk for incident diabetes, additively to age, BMI, CRP, HDL-cholesterol among Turks. Systemic inflammation concomitant with prevailing MetS might turn apoA-I into proinflammatory particles.

Abstract
BACKGROUND/AIMS Hepatocyte apoptosis is an important and invasive predictor of liver injury and fibrosis in non-alcoholic fatty liver disease (NAFLD). Increased gamma-glutamyltranspeptidase (GGT) level is frequently observed in NAFLD. Hepatocyte growth factor (HGF) stimulates fibrogenesis and is correlated with GGT. The study aimed to determine whether GGT can distinguish NAFLD patients at high risk. METHODOLOGY Fifty biopsy-proven NAFLD patients (M/F: 24/26) were divided as the normal GGT group (n = 25) and the high GGT group (n = 25) (each patients' GGT > two fold of upper-limit of normal). Liver histology was graded according to Brunt et al. TNF-sRp55, caspase-3 and 8, NFkappaB and Bcl-2 were measured by immunohistochemical methods. For statistical analysis, Student's t test, chi-square test, multivariate regression analysis and the area under receiver operating characteristic (ROC) curve were used. RESULTS The high GGT group had significantly higher NFkappaB, caspase-3 and 8, and Bcl-2 levels (54.52 +/- 26.02, p = 0.002; 55.95 +/- 27.18, p = 0.002; 47.85 +/- 28.04, p = 0.001; 11.19 +/- 12.33, p = 0.016, respectively). Serum TNF-sRp55 levels of both groups were similar (2922.93 +/- 307.26, and 2885 +/- 194.47; p = 0.78). Differences in reference to histological steatosis grade and inflammation were not significant. However, fibrosis stage was higher in the high GGT group (p = 0.048). CONCLUSION Multinominal logistic regression analysis showed that increased GGT level was a risk factor for advanced fibrosis in NAFLD (OR: 1.0, CI: 0.98-1.01; p =0.032). Using serum GGT levels the area under the ROC curve for the prediction of advanced fibrosis was 0.74 (95% CI: 0.54-0.94). The serum GGT cut-off value for the prediction of advanced fibrosis was 96.5 U/L; with 83% sensitivity and 69% specificity.

Abstract
The aim of this study was to evaluate risk factors of dental caries in preschool children in Istanbul. Five nursery schools in Istanbul were included and results of 598 students' were collected. Subjects were orally examined. Socio-demographic data were obtained from the records and from parents. Oral examination data were recorded on examination forms in accordance with the WHO criteria. Bivariate analyses were conducted using chi-square test Multivariate analyses were then performed to estimate the simultaneous impact of the independent variables on dft. Logistic regression analysis was performed in stages. In the study, while although the percentage of children had 60% caries and 0 results at the age of 3, this percentage drops to 15.3% at the age 6. 36%Thirty-six percent of the students have insufficient oral hygiene. Statistically meaningful difference was ascertained in chi-square analysis related to age, mother's education level, and father's occupation. When the variables with statistically meaningful difference are estimated with logistic regression analysis, the age and father's father's occupation turned out to be the risk indicators that affect dft level.

Abstract
A patient with a severe neonatal variant of 3-methylcrotonyl-CoA carboxylase (MCC) deficiency is reported. The first child of healthy consanguineous Turkish parents presented on the second day of life with dehydration, cyanosis, no sucking, generalized muscular hypotonia, encephalopathy, respiratory depression requiring mechanic ventilation, macrocephaly, severe acidosis and hypoglycaemia. Elevated C5-OH-carnitine in dried blood spot by tandem MS and elevated urinary excretion of 3-hydroxyisovaleric acid and 3-methylcrotonylglycine suggested MCC deficiency, confirmed by enzyme analysis in cultured fibroblasts. Cerebral ultrasonography and cranial CT findings revealed progressive changes such as disseminated encephalomalacia, cystic changes, ventricular dilatation and cerebral atrophy. Treatment with high-dose biotin and protein-restricted diet was ineffective and the patient died at the age of 33 days with progressive neurological deterioration. Mutation analysis revealed a homozygous mutation in the splice acceptor site of intron 15 in the MCC beta-subunit. Early-onset severe necrotizing encephalopathy should be included in the differential diagnosis of isolated MCC deficiency.

Abstract
We aimed to navigate the surgeon regarding the localization of the main anatomical structures at the anterior part of the ankle joint, in order to find easily the safest anatomical points with reference to the superficial peroneal nerve (SPN), in particular for anterolateral portal placement in ankle arthroscopy. Sixty-three ankles in 36 fresh cadavers were dissected. In all specimens we examined (1) the distance between the SPN bifurcation and the most distal point of the lateral malleolus; and at the level of ankle joint, (2) the number of SPN, (3) the distance between the medial and intermediate dorsal cutaneous nerves, which are branches of the SPN, (4) the localization of the peroneus tertius (PT) tendon in relation to the lateral malleolus, (5) the width of the extensor digitorum longus (EDL) tendon, (6) the relationship of the PT tendon and (7) the relationship of the extensor hallucis longus (EHL) tendon with the SPN. The results were as follows: (1) In 41 ankles with bifurcation (65%) the average distance was 71.8+/-35.3 mm. (2) There were two SPN branches in 39 (62%), three branches in seven (11%) and one branch in 17 (27%) cases. (3) In 39 ankles with two branches of the SPN, the mean distance was 15.2+/-7.1 mm. (4) The lateral border of the PT tendon was positioned a mean distance of 20.8+/-3.3 mm proximal and 25.2+/-5.8 mm medial to the reference points. (5) The mean width was 10.1+/-2.9 mm. (6) In 42 ankles (67%) the distance between the lateral border of the PT tendon and the SPN was a mean of 6.2+/-6.6 mm, median of 3 mm (range 0-22 mm lateral to the tendon). (7) In 56 cases (89%) a branch of the SPN was found a mean of 6.6+/-4 mm and a median of 6 mm lateral to the EHL tendon, and in seven cases (11%) on the tendon. According to our study, in ankle arthroscopy the risk of the SPN injury is maximal in the 0-3 mm lateral to the PT tendon. To avoid injury to the SPN, the safest placement of the anterolateral portal is 4 mm lateral to the PT tendon.

Abstract
Renal candidiasis in the neonate is encountered infrequently. We report a newborn with ichthyosis, who during the hospital course had five episodes of culture-proven sepsis, probably due to skin lesions. For these infections various antibiotic combinations were used. During the therapy of the last sepsis attack, unilateral hydronephrosis developed secondary to renal candidiasis. Percutaneous nephrostomy with amphotericin B irrigation, coupled with five weeks of intravenous amphotericin B therapy was successful. We believe that with this approach the mortality and morbidity of renal candidiasis could be reduced.

Abstract
Factor VII deficiency is a rare congenital coagulopathy. Prolonged prothrombin time with normal partial thromboplastin time indicates factor VII deficiency. For the definitive diagnosis, the specific factor VII level should be investigated. We report a seven-day-old, male, full-term newborn who was admitted with the diagnosis of sepsis. Hematological tests revealed prolonged prothrombin time and a factor VII level of five percent. After antibiotic therapy and fresh frozen plasma replacement his clinical status improved but the prothrombin time continued to be prolonged. On the 14th day, just before the end of antibiotic therapy, the infant died of sudden intracerebral hemorrhage. In this article, the clinical features and management of factor VII deficiency are discussed.

Abstract
Breast milk samples from mothers of breast-fed, healthy, term newborns with unexplained prolonged jaundice were analyzed for beta-glucuronidase activity. Mean enzyme activity was 75.7 +/- 34.5 modified Sigma units/ml in the breast milk samples ingested by the study group of jaundiced babies (n = 25) and 82.2 +/- 40.1 modified Sigma units/ml in the samples ingested by the control group of non-jaundiced babies (n = 20) (p > 0.05). Enzyme activities at 2, 3 and 4 postnatal weeks were 101.0 +/- 39.9, 66.0 +/- 20.7 and 57.0 +/- 22.4 modified Sigma units/ml in the study group and 87.9 +/- 36.1, 58.5 +/- 15.0 and 88.3 +/- 49.1 modified Sigma units/ml in the controls. The differences were not statistically significant (p > 0.05). We conclude that breast milk beta-glucuronidase activity may be a contributory factor, in the presence of other variables, in hyperbilirubinemia but it is neither the main nor the only cause of prolonged jaundice in neonates.

Abstract
A case of neonatal suppurative parotitis due to Klebsiella pneumoniae is described. This is the first case reported in the last 20 years. Infection with unusual microorganisms should be taken into account when planning antibiotic treatment, especially in hospital acquired infections of the salivary glands in the newborn.
