Abstract
INTRODUCTION Acute hyperammonemic encephalopathy is associated with distinct brain MRI findings, namely, hyperintensity in T2-weighted sequences as well as restricted diffusion in diffusion-weighted imaging with accentuation in the insular cortex and cingulate gyrus. The pathophysiology and the histopathological correlates of these characteristic MRI findings are largely unknown. CASE REPORT We present a 57-year-old male with a history of chronic alcohol abuse, liver cirrhosis and portal hypertension, and a clinical syndrome (variceal bleeding, depression of consciousness, seizures), elevated plasma ammonia levels, and characteristic brain MRI abnormalities suggestive of acute hyperammonemic encephalopathy. A postmortem histopathological examination revealed extensive hypoxic ischemic encephalopathy without evidence for metabolic encephalopathy. No episodes of prolonged cerebral hypoxemia were documented throughout the course of the disease. We conducted a review of the literature, which exhibited no reports of hyperammonemic encephalopathy in association with characteristic brain MRI findings and a consecutive histopathological examination. CONCLUSION This is the first report of a patient with acute hyperammonemic encephalopathy together with characteristic brain MRI findings and a histopathological correlation. Although characteristic MRI findings of acute hyperammonemic encephalopathy were present, a histopathological examination revealed only hypoxic pathology without signs of metabolic encephalopathy.

Abstract
Hepatitis C virus infection is causing chronic liver disease, cirrhosis, and hepatocellular carcinoma. By combining direct-acting antivirals (DAAs), high sustained virologic response rates (SVRs) can be achieved. Resistance-associated substitutions (RASs) are commonly observed after DAA failure, and especially nonstructural protein 5A (NS5A) RASs may impact retreatment options.1-3 Data on retreatment of DAA failure patients using first-generation DAAs are limited.4-7 Recently, a second-generation protease- and NS5A-inhibitor plus sofosbuvir (voxilaprevir/velpatasvir/sofosbuvir [VOX/VEL/SOF]) was approved for retreatment after DAA failure.8 However, this and other second-generation regimens are not available in many resource-limited countries or are not reimbursed by regular insurance, and recommendations regarding the selection of retreatment regimens using first-generation DAAs are very important. This study aimed to analyze patients who were re-treated with first-generation DAAs after failure of a DAA combination therapy.

Abstract
BACKGROUND Staging of liver fibrosis in patients with chronic hepatitis C (CHC) is recommended prior to anti-viral therapy. As vWF-Ag was shown as a predictor of portal hypertension, decompensation and mortality in patients with liver cirrhosis, we performed this study to investigate if vWF-Ag is able to predict different fibrosis stages and if it is comparable to other fibrosis scores. AIM To investigate if vWF-Ag is able to predict different fibrosis stages and if it is comparable to other fibrosis scores. METHODS We analysed 294 patients with chronic hepatitis C who underwent biopsy. We assessed stage of liver fibrosis according to Metavir, measured vWF-Ag and calculated different fibrosis scores (APRI, FCI, FORNS, FI, Fib-4) and compared them by AUCs. We also calculated a new score: vWF-Ag/thrombocytes (VITRO score) for prediction of fibrosis. RESULTS vWF-Ag levels were increasing with stage of fibrosis: F0: vWF-Ag was median 136.5%, FI 140.6%, FII 157.5%, FIII 171.0%, FIV 252.0%; P < 0.001. vWF-Ag and VITRO score produced AUCs of 0.7 and 0.72 for ≥F2, comparable to the AUCs of APRI, Fib-4, FORNS with 0.75, 0.65 and 0.64 (P > 0.05). For ≥F3 AUCs were 0.79 and 0.86 for vWF-Ag and VITRO score, comparable with AUCs of 0.79, 0.86 and 0.87 for APRI, Fib-4 and FORNS. Cirrhosis shows AUCs of 0.84 and 0.89 for vWF-Ag and VITRO score, APRI, Fib-4 and FORNS showed similar results with AUCs of 0.82, 0.88 and 0.87. CONCLUSIONS vWF-Ag and VITRO score offer an easy possibility to evaluate the stage of fibrosis to diagnose subclinical cirrhosis in patients with chronic hepatitis C. Both vWF-Ag and VITRO score show equal performance in comparison to other fibrosis scores assessed in our study.

Abstract
BACKGROUND The IL28B genotype in rs12979860 predicts success of peginterferon/ribavirin (PEG/RBV) therapy in patients with chronic hepatitis C (CHC). Recently, a dinucleotide frame shift variant in ss469415590 (TT or ΔG) was described, which generates the novel interferon lambda 4 protein (IFNL4). IFNL4 ss469415590 (ΔG) allele carriers have an impaired clearance of HCV infection and response to IFN-α therapy. In this study, we compared the role of IFNL4 polymorphism with the two commonly used IL28B SNPs rs12979860 and rs8099917 on response to PEG/RBV in patients with CHC. AIM To compare the role of IFNL4 polymorphism with the two commonly used IL28B SNPs rs12979860 and rs8099917 on response to PEG/RBV in patients with CHC. METHODS A total of 754 PEG/RBV patients treated (male/female = 484/270; Caucasians: 98.8%; mean age: 42.8 [CI 95%: 42.0-43.6] y; genotype (GT)1: n = 435, GT2: n = 23, GT3: n = 185, GT4: n = 114) were investigated. Liver fibrosis was assessed by liver biopsy in 456 patients. Single nucleotide polymorphisms (SNPs) in ss469415590, rs12979860 and rs8099917 were analysed by RT-PCR system. RESULTS Of the patients, 12.9% (n = 97) had the ss469415590 ΔG/ΔG genotype (IFNL4), 51.3% (n = 387) were heterozygous (TT/ΔG) and 35.8% (n = 270) had TT/TT. IFNL4 polymorphism was independently associated with SVR in GT1 (OR: 2.539, CI 95%: 1.629-3.021, P < 0.001) and GT4 (OR: 12.573, CI 95%: 3.427-46.133, P < 0.001), but not in GT3 (OR: 1.514, CI 95%: 0.933-2.458, P = 0.093). IFNL4 correlated strongly with rs12979860 (ρ = 0.988, P < 0.001), but only moderately with rs8099917 (ρ = 0.598, P < 0.001). CONCLUSIONS These findings underscore the role of IFNL4 for treatment response in patients with CHC genotypes 1 and 4. However, due to its strong correlation with rs12979860 in IL28B, there is no benefit in additional testing for IFNL4 for treatment prediction in Caucasian patients. By contrast, IFNL4 improves prediction of response to interferon-based therapies, if SNP rs8099917 is used.

Abstract
BACKGROUND The introduction of direct-acting anti-virals has increased sustained virological response (SVR) rates in chronic hepatitis C genotype 1 infection. At present, data on long-term durability of viral eradication after successful triple therapy are lacking. AIM To evaluate the long-term durability of viral eradication in patients treated with triple therapy, including direct-acting anti-virals. METHODS Patients who participated in randomised, controlled trials or an extended access programme of treatment with peginterferon-α2a/ribavirin in combination with a direct-acting anti-viral (telaprevir, danoprevir, faldaprevir, simeprevir, mericitabine, balapiravir) were followed after achieving SVR. The median follow-up after the patients was 21 (range: 7-64) months. RESULTS One hundred and three patients with chronic hepatitis C genotype 1 infection [f/m: 34/69; GT-1b: 67 GT-1a: 34, GT-4: 2; mean age: 47.6 years (45.5-49.7; 95% CI)] achieving a SVR triple therapy were followed. Two cases of late relapses (2/103, 1.9%; 95% CI: 0.24-6.8) were observed. One patient was cirrhotic, both carried the genotype 1b and completed the prescribed treatment. The relapses occurred 8 and 12 months after cessation of anti-viral treatment. Cloning sequencing revealed identical sequence in both patients. Resistance analysis revealed no presence of viral resistance. CONCLUSION Like the SVR after peginterferon-α2/ribavirin combination treatment, HCV eradication after triple therapy remains durable after long-term follow-up.

Abstract
BACKGROUND Sorafenib is the new reference standard for patients with advanced hepatocellular carcinoma (HCC). AIM To identify prognostic factors in sorafenib-treated HCC patients and to evaluate outcomes with respect to liver function. METHODS In this retrospective study, 148 HCC patients received sorafenib 400 mg b.d. across 11 Austrian institutions. Seventy-eight HCC patients who received best supportive care (BSC) in the pre-sorafenib era served as a control. RESULTS In sorafenib-treated patients, low baseline α-fetoprotein, low Child-Pugh (CP) score, compensated cirrhosis, and low baseline aspartate aminotransferase (AST) were associated with significantly longer overall survival (OS) on univariate analysis. CP score and baseline AST remained independent prognostic factors on multivariate analysis. In patients with Barcelona Clinic liver Cancer (BCLC) stage B or C HCC (sorafenib: n = 139; BSC: n = 39), CP-A patients had a median OS of 11.3 (sorafenib [n = 76]) vs. 6.4 (BSC [n = 17]) months (P = 0.010), and CP-B patients had a median OS of 5.5 (sorafenib [n = 55]) vs. 1.9 (BSC [n = 22]) months (P = 0.021). In the sorafenib group, median OS according to baseline AST was 11.8 (<100 U/L [n = 58]) vs. 3.9 (≥100 U/L [n = 15]) months for CP-A patients (P = 0.127), and 6.5 (<100 U/L [n = 33]) vs. 2.1 (≥100 U/L [n = 21]) months for CP-B patients (P = 0.011). There was no survival difference between sorafenib and BSC in patients with BCLC stage D HCC (1.5 vs. 1.4 months; P = 0.116). CONCLUSIONS Sorafenib was associated with improved survival in both CP-A and CP-B patients. In CP-B patients, baseline AST may be helpful in determining which patients are most likely to benefit from sorafenib.

Abstract
Chronic hepatitis C is a leading cause of end-stage liver disease and, with a worldwide prevalence of up to 3%, is a pandemic infectious disease. Austria, like most western European countries can be considered as a low prevalence country. This analysis aimed to assess the distribution of hepatitis C virus (HCV) genotypes in patients with chronic HCV infection in Upper Austria. Between September 1992 and December 2006, we identified 1,318 consecutive patients who tested positive for HCV RNA. Genotyping was routinely performed in 1,239 of the 1,318 patients, and in a subgroup of 617 patients data on the source of transmission were collected. Additionally we obtained data on liver histology and body mass index in a subsample of 273 of the 617 patients. Hepatitis C genotypes 1, 2, 3, 4, 6 and co-infections were found in 80.4%, 4.5%, 12.3%, 2.7%, 0.1% and 0.2% of the patients, respectively. There was a highly significant age difference in relation to gender at the time of diagnosis of chronic hepatitis C, with women being older than men (men: 45.0 years; women: 49.3 years; p<0.0001). The number of new cases of chronic hepatitis C decreased substantially over the last decade, but although risk factors for obtaining HCV are well established, we did not find a decrease in the age of first diagnosis. Besides consistent screening in defined risk groups it is important to raise awareness for risk factors for HCV acquisition and liver disease progression.

Abstract
BACKGROUND AND STUDY AIMS The small bowel is anatomically difficult to examine; disease conditions are rarely located in it, but can be serious. Neither conventional radiography nor push enteroscopy has sufficient sensitivity and specificity to detect distinct lesions. Wireless capsule endoscopy can theoretically allow imaging of the entire small bowel, with only minimal discomfort for the patient. PATIENTS AND METHODS Between November 2001 and May 2003, 191 patients received 195 capsules. Data were collected retrospectively from consecutive patients in three centers. The indications for capsule endoscopy were obscure or occult bleeding, suspected Crohn's disease, or other reasons in 151, 25, and 15 patients, respectively. The clinical outcome after 6 months was evaluated on the basis of interviews with patients or relatives. RESULTS Visualization of the entire small bowel was adequate in 78.4 % of the examinations. The colon was not reached in 16.9 % of cases, and there were minor technical problems in 4.6 %. Relevant pathological findings were identified in 56.2 % of 151 patients with obscure bleeding or iron-deficiency anemia (64 % of whom received blood transfusions). The most common findings were angiodysplasia in 39.7 % of cases and ulcers of the small bowel in 7.3 %. In addition, individual cases of tumors and parasitic worms were detected. Seven of the 25 patients with suspected Crohn's disease (28 %) had the disease confirmed. Three of five patients with polyposis syndrome of the colon were found to have polyps in the small bowel. CONCLUSIONS Wireless capsule endoscopy can be recommended as part of the routine work-up in patients with obscure bleeding or iron-deficiency anemia. In patients with Crohn's disease, the method may be helpful in establishing or ruling out the diagnosis.

Abstract
BACKGROUND The aim of this retrospective study was to analyze the safety and efficacy of the conservative approach in the management of ectopic pregnancy. METHODS Thirty-five women with a tubal ectopic pregnancy, from 1990 to 1995, were subdivided into 2 treatment groups. Inclusion criteria were the following: tubal diameter < 3 cm, free fluid < 100 ml, no embryo heart activity, haemodynamic stability. Desire of future fertility and informed consent were requested. Eighteen women were treated with a single intramuscular injection of methotrexate, whereas in 17 cases expectant management was adopted. RESULTS In the first group 2 cases required surgical treatment (resolution rate = 89%). In the second group no surgery was needed and spontaneous resolution was achieved in all cases (100%). In both groups the average resolution time was about 17 days. Serum hCG-beta levels were monitored daily until resolution. The initial hCG-beta value and its following trend seem to be the most important prognostic factors. CONCLUSIONS More studies are indeed needed to establish the effect of conservative management on fertility after ectopic pregnancy.

Abstract
Choroid plexus cysts (CPC) in the fetus are still the subject of considerable debate in the literature. Because of their association with aneuploidy, and especially with trisomy 18, of which they are an ultrasonographic marker, the detection of fetal CPC now poses the problem of how these cases should be managed, since most occur in young women (there being no correlation between CPC and age), and since the incidence among the general population is fairly high (around 1%). With the aim of contributing further to the debate, a retrospective study was performed of all cases of fetal CPC diagnosed in our Centre between January 1984 and August 1994, together with a review of the relevant literature. There were 95 cases of fetal CPC with complete neonatal and necroptic data available. These cases included women recruited in the course of routine screening for congenital malformations carried out in our Centre at 14 and 21 weeks gestation, women referred to us from other Centres, and women recruited in the course of amniocentesis indicated for those aged over 35. In all cases in which fetal CPC was detected, a careful ultrasonographic examination was performed to exclude the presence of even the smallest morphologic anomaly. Whenever the fetus was found to have an anomaly karyotyping was done. If the CPC was not associated with any morphologic anomaly, karyotyping was proposed only to those women at risk of aneuploidy because of their age. There were 11 cases of trisomy 18, all of which presented morphologic anomalies associated with CPC. Some of these anomalies where "minor", however, and therefore difficult to assess even when a careful ultrasonographic examination was performed by an experienced operator (Intra ventricular septal defect, single umbilical artery). In 2 cases, CPC was associated with trisomy 21. Both women were aged over 35. All the other cases of CPC not associated with morphologic anomaly were normal on postnatal examination. From a meta-analysis of the literature, two distinct management protocols emerge for the problem of "isolated CPC detected at ultrasonographic examination". One group of authors recommends karyotyping for all women with fetal CPC, considering the presence of CPC in itself a risk factor for aneuploidy. The second group, to which we ourselves belong, believes it is sufficient to perform a careful ultrasonographic examination so as to exclude the presence of other morphologic anomalies associated with the CPC. Karyotyping should be proposed only to women at risk of aneuploidy because of their age (> 35). A review of the biggest series reported in the literature shows that, of a total of 1670 fetuses with CPC, 94 were trisomy 18. None of the cases of CPC "in isolation" emerged as being associated with this aneuploidy. However, numerous cases of trisomy 18 have been described in which CPC is associated with "minor" morphologic anomalies in the fetus which may be difficult to detect. It is therefore essential to perform a careful ultrasonographic examination in all cases of CPC, preferably in a Centre with specialist knowledge of ultrasonography. If this option is not available, then karyotyping of all women with fetal CPC is clearly advisable.

Abstract
The aim of this study was to assess whether a screening program for fetal cardiac malformations is justified in a low-risk population, and which factors influence its accuracy. The fetal heart was evaluated in 7024 pregnant women at 20-22 weeks, and evaluation was repeated at a more advanced gestational age in 9% of cases. Cardiological follow-up was continued postnatally until 2 years of age. The overall prevalence of cardiac anomaly was 0.93%. The incidences of major and minor defects were 0.44% and 0.48%, respectively. There were 23 true positives (0.33%): in 20 cases, the diagnosis was made in the second trimester, and 13 women (65%) chose termination of pregnancy. Seventeen of the 20 cases identified in the second trimester were serious malformations. There were 42 false negatives (0.60%). Of these, 12 had signs of cardiac dysfunction at birth or within the 1st month of life, and three of them died as a result of their cardiac anomaly. There were eight false positives (0.11%), all of a minor type. Six abnormal karyotypes, out of a total of 21 performed in the true-positive group (28.5%), were found. In addition, five of the 42 newborns in the false-negative group had trisomy 21. The overall sensitivity was 35.4%, and 61.3% for major defects. The accuracy in two distinct periods was estimated because the level of experience of the operators was different: sensitivity was 45.2% in period 1 (1986-88) (77.8% for major defects) and 26.5% in period 2 (1989-92) (52.9% for major defects). We conclude that a fetal heart screening program in the obstetric population is justified. It defines a high-risk group for karyotyping, allows planning of delivery in a tertiary center or the choice of terminating the pregnancy for the parents and appears to have a positive cost-benefit ratio. A crucial factor is the level of training and experience of the operators, who need specific teaching support.

Abstract
A total of 149 women with postmenopausal bleeding underwent transvaginal sonography, hysteroscopy and dilatation and curettage in order to study the diagnostic accuracy of several ultrasound parameters in assessing endometrial pathology and to determine the most sensitive cut-off value of endometrial thickness for the exclusion of endometrial lesions. In distinguishing pathological from normal endometrium, transvaginal sonography showed a sensitivity of 69.3%, specificity of 82.7%, positive predictive value of 74.1% and negative predictive value of 72.1%. In detecting premalignant and malignant endometrial pathology, transvaginal sonography showed a sensitivity, specificity, positive predictive value and negative predictive value of 55%, 96.1%, 68.7% and 93.2%, respectively. Considering endometrial thickness as a single parameter, the most sensitive cut-off for defining normality was 4 mm; nevertheless, in the group of patients that had an endometrial thickness less than 4 mm, there was one case of malignancy (sensitivity, 95.2%; specificity, 49.4%; positive predictive value, 57.3%; and negative predictive value, 93.5%). Transvaginal sonography combined evaluation (morphology, thickness and color Doppler) showed a poor diagnostic accuracy in detecting endometrial pathology and in differentiating between endometrial benign lesions, endometrial polyps and adenocarcinoma in women with postmenopausal bleeding. Endometrial thickness evaluated with transvaginal sonography was preferable but not sensitive enough to exclude endometrial pathology.

Abstract
Two thousand and ninety-seven unselected pregnant women bearing 2114 fetuses were examined by transvaginal sonography at 14 weeks of gestational age and rescreened via transabdominal sonography at 21 weeks (excluding those who chose termination of pregnancy). Twenty-five of 47 anomalies were correctly identified at the first scan, 15 malformations were missed and detected only during the scan, two were identified later in pregnancy, and five were identified after birth. Ten of 12 abnormalities were detected correctly on the basis of ultrasonographic findings. Transvaginal sonographic screening for fetal malformation, in our experience, permits the detection of more than 50% of all fetal structural defects and 75% of all aneuploidies early in pregnancy.

Abstract
The diagnostic accuracy of transvaginal sonography (TVS) and hysteroscopy in the assessment of endometrial pathology was studied comparing retrospectively both methods with the results of histologic findings after dilatation and curettage (D&C) performed in the last four years on 467 patients, 155 of whom were in postmenopause. Endometrial thickness, tissue texture, myometrial invasion and haemodynamic characteristics were studied with TVS. Uterine cavity, endometrial patterns and superficial vascularization were evaluated by hysteroscopy. For the purpose of this study all histologic findings were subdivided to a) normal (206 cases); b) benign lesions (240 cases); c) atypical hyperplasia or adenocarcinoma (21 cases). In our experience hysteroscopy was superior to TVS in detecting endometrial pathology. Both techniques were more sensitive in detecting premalignant and malignant lesions. Considering endometrial thickness evaluated with TVS as a single parameter in patients in postmenopause, we found that the most sensitive cut-off for defining normality was 3 mm; nevertheless, in the group of patients that had an endometrial thickness equal to or less than 3 mm there were 2 cases of malignancy. Therefore, neither TVS nor hysteroscopy are sufficiently reliable to replace curettage in the diagnosis of endometrial pathology.

Abstract
Endocardial fibroelastosis is characterized by an abnormal thickening of the endocardium of one or both ventricles; the disorder may occur with or without other cardiac anomalies. A diagnosis of endocardial fibroelastosis in utero using fetal echocardiography may be made on the basis of increased echodensity of the endocardium and poor contractility of the ventricle. We describe a case of very early diagnosis of fibroelastosis and aortic valve stenosis observed in utero at 14 weeks' gestation by transvaginal echocardiography.

Abstract
The Authors examine the correlation between hypertensive disorders of pregnancy and fetal growth. The results of a study of 342 pregnancies, confirm a significant correlation between hypertension and fetal growth retardation. These findings, so evident in moderate and severe hypertension, have also been confirmed in cases of mild hypertension. The medical treatment also in the pregnancies with mild hypertension, and a larger utilisation of operative deliveries, determined a decrease in perinatal mortality and morbidity.
