Abstract
IntroductionInflammatory bowel diseases (IBDs) have high social impact. Aetiology is still unknown, however multifactorial genesis is surely implicated. We tried to correlate IBDs and psychological distress through evaluated psychometrical instruments and subsequently to relate subjective influences with gastroenteric clinical manifestation, defining new critical elements on which IBD are based.MethodsIn our study, we included 57 participants, selected according to their diagnosis, between those attending our gastrointestinal ambulatory: 26 had Chron's disease, while 31 had ulcerative colitis. 78 people without gastroenteric or psychiatric disorder were also included in the study as control group. Psychometric questionnaires were administered to evaluate anxiety and depressive symptoms, quality of live, self-efficacy and resilience (Fig. 1).ResultsLevels of anxiety and depression were higher in patients with IBDs than in the control group. STAI-Y highlighted higher state anxiety and trait anxiety levels in first group. HADS showed higher scores in ill patients, as well as CD-RISC showed a more impaired resilience. EQ-VAS, PGWBI and GSE revealed significant differences in health status, psychological wellness and self-efficacy between the two groups.ConclusionsIBDs seem related to psychological diseases. Affected patients have higher anxiety and depression levels than general population as well as lower self-efficacy and resilience. Those elements being strictly linked to physical discomfort contributes to develop a loop in which patients get caught. Creating a model of integrated cooperation between gastroenterologist and psychiatrist during treatment of patients with IBDs seems fundamental to grant at once all the professional figures each patient needs for better care.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
OBJECTIVE Constipation is a common symptom affecting up to 30% of the Western population and is strongly associated with the presence of intestinal methanogens, which may directly inhibit motor activity. Two recent studies performed on adult and children affected by chronic constipation showed that the supplementation with L. reuteri significantly improved bowel movements. Whether its action is related to a decreasing of methane (CH4) production has never been tested. We have therefore designed a study aimed at testing this hypothesis. PATIENTS AND METHODS Data of 20 adults (12 females, mean age 36.2 ± 13.7) affected by functional constipation, treated with the probiotic L. reuteri (DSM 17938) for 4 weeks who performed a H2/CH4 lactulose breath test (LBT) in our institution showing a CH4 production higher than 5 ppm were retrospectively analyzed from March to June 2015. Data recorded in their stool diary, reporting the frequency of defecations and stool consistency were also analysed, as well as the result of the LBT performed at the end of the treatment with L. reuteri. RESULTS Four weeks of L. reuteri administration was associated with a significant decrease of mean CH4 production determined by LBT (from 20.8 ± 15 to 8.9 ± 8.6; p < 0.0001 CI 95%) and of AUC value (from 5101.5 ± 3571.13 to 2128.4 ± 2110.8; p < 0.0001 CI 95%). Moreover, a total disappearance of CH4 production (< 5 ppm at LBT) was observed in 11 patients, while, we did not observe any significant decrease of H2 production (from 13.2 ± 8.8 to 11.4 ± 7.3, CI 95%, n.s.). CONCLUSIONS This study highlights for the first time the beneficial effect of Lactobacillus reuteri (DSM 17938) on chronic constipation, via a significant decrease of CH4 production.

Post-liver transplant intrahepatic cholestasis: etiology, clinical presentation, therapy. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2017; 21:23-36.

Abstract
Post-liver transplant intrahepatic cholestasis is consequent to the impairment of bile flow or formation. It may develop in the early (within 6 months) or in the late (more than 6 months) post-liver transplant period and different causes may be recognized according to the time elapsed from a liver transplant. The raise at various degrees of serum bilirubin, alkaline phosphatase, and gamma-glutamyl transpeptidase, with or without increased transaminases levels, are common hematochemical findings. Liver histology is helpful for diagnostic assessment, and sometimes crucial to differentiate among possible causes of cholestasis. Although timely treatment of underling conditions as well as supportive care may resolve post-liver transplant intrahepatic cholestasis, the risk of graft loss and retransplantation are remarkable. For this reason, post-liver transplant intrahepatic cholestasis should be managed in collaboration with the LT center, and treatment should be devolved to expert hepatologists.

Abstract
Drug-induced liver injury (DILI) is a common and underestimated cause of liver disease. Several drugs and other xenobiotics can be the cause of different clinicopathologic patterns of liver disease. Steatosis and steatohepatitis are rare but well-documented types of DILI. Over the past decades commonly used drugs like amiodarone, tamoxifen, irinotecan, methotrexate, valproic acid and glucocorticoids have been recognized to be associated with steatosis. Even though the pathophysiological pathways are still only partially understood, inhibition of mitochondrial beta-oxidation, reduced very low-density lipoprotein secretion, insulin resistance induction and increased de novo synthesis or increased liver uptake of fatty acids are considered the main pathogenic mechanisms through which drugs can lead to hepatic steatosis. On the other hand, fatty liver itself is a very common clinical condition, and there is a growing awareness of the potential risk factors for DILI due to the underlying metabolic condition itself.

Abstract
A drug-induced liver injury (DILI) is defined as a liver injury caused by exposure to a drug or a non-infectious toxic agent with a variable degree of organ dysfunction. A better understanding of DILI epidemiology has been obtained in recent years with the institution of international registries in the United States and Europe. Despite the advances in the understanding and characterization of the phenomenon, DILI remains an exclusion diagnosis so, probability scores and the analysis of literature reports are useful tools in dealing with a suspected DILI. Idiosyncratic DILI can be considered a relatively rare event but it is one of the leading causes of acute liver failure. Thus, proper management is essential to avoid serious consequences. Here, we present an updated review of diagnostic and classification criteria of DILI. Prognostic tools, and principles of management and therapy have also been briefly discussed.

Abstract
OBJECTIVES To summarize the different clinical features of drug-induced acute liver failure, the diagnostic work-up, conservative management and the prognostic scores currently used to list patients for liver transplantation. EVIDENCE AND INFORMATION SOURCES The current review is based on an analysis of the current literature and the caseload experience of the Authors on this topic. STATE OF THE ART Drug-induced liver injury is the leading cause of acute liver failure in the adult population in Western countries, with a transplant-free survival rate of less than 50%. Main subtypes include paracetamol and idiosyncratic drug-induced injury, which differ in epidemiology, clinical course, prognosis and conservative management. In cases of a high likelihood of death, urgent hepatic transplantation is indicated, but the decision whether and when to put a patient with drug-induced acute liver failure on the list for urgent liver transplant is extremely difficult and requires constant interdisciplinary exchange and continuous updating of the clinical picture. CONCLUSIONS Intensive management should be done in a clinical tertiary referral center which has a specialized team of hepatologists and a liver transplant center.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is the results of a chronic inflammatory process deriving from disequilibrium between self-microbiota composition and immune response. METHODS New evidence, coming from Clostridium difficile infection, clearly showed that active and powerful modulation of microbiota composition by fecal microbiota composition (FMT) is safe, easy to perform, and efficacious, opening new frontiers in gastrointestinal and extra-intestinal diseases. FMT has been proposed also for IBD as well as other non-gastrointestinal conditions related to intestinal microbiota dysfunctions, with good preliminary data. RESULTS In this setting, ulcerative colitis (UC) represents one of the most robust potential indications for FMT after C difficile colitis. CONCLUSIONS In the present review, we focus on FMT and its application on ulcerative colitis, clarifying mechanisms of actions and efficacy data, trough completion of a meta-analysis on available randomized, controlled trial data in UC. Because microbiota is so crucially involved in this topic, a short review of microbial alterations in UC will also be performed.

Abstract
OBJECTIVES Faecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection (CDI). Although a single faecal infusion is usually sufficient to eradicate CDI, a considerable number of patients need multiple infusions to be cured. The aim of this study was to identify predictors of failure after single faecal infusion in patients with recurrent CDI. METHODS We included patients with recurrent CDI prospectively treated with FMT by colonoscopy. By means of univariate and multivariate analysis, variables including female gender, age, number of CDI recurrences, severity of CDI, hospitalization, inadequate bowel preparation, unrelated donor, and use of frozen faeces, were assessed to predict failure after single faecal infusion. RESULTS Sixty-four patients (39 women; mean age 74 years) were included. Of them, 44 (69%) were cured by a single faecal infusion, whereas 20 (31%) needed repeat infusions. Overall, FMT cured 62 of 64 (97%) patients. In the subgroup of patients with severe CDI, only eight of 26 (30%) were cured with a single infusion. At multivariate analysis, severe CDI (OR 24.66; 95% CI 4.44-242.08; p 0.001) and inadequate bowel preparation (OR 11.53; 95% CI 1.71-115.51; p 0.019) were found to be independent predictors of failure after single faecal infusion. CONCLUSIONS Severe CDI and inadequate bowel preparation appear to be independent predictors of failure after single faecal infusion in patients treated with FMT by colonoscopy for recurrent CDI. Our results may help to optimize protocols and outcomes of FMT in patients with recurrent CDI.

Abstract
BACKGROUND In HCV-infected cirrhotic patients with successfully treated early hepatocellular carcinoma (HCC), the time to HCC recurrence and the effects of sustained viral eradication (SVR) by interferon (IFN)-based or IFN-free regimens on HCC recurrence remain unclear. AIM To perform an indirect comparison of time to recurrence (TTR) in patients with successfully treated early HCC and active HCV infection with those of patients with SVR by IFN-based and by IFN-free regimens. METHODS We evaluated 443 patients with HCV-related cirrhosis and Barcelona Clinic Liver Cancer Stage A/0 HCC who had a complete radiological response after curative resection or ablation. Active HCV infection was present in 328, selected from the Italian Liver Cancer group cohort; 58 patients had SVR achieved by IFN-free regimens after HCC cure, and 57 patients had SVR achieved by IFN-based regimens after HCC cure. Individual data of patients in the last two groups were extracted from available publications. RESULTS TTR by Kaplan-Meier curve was significantly lower in patients with active HCV infection compared with those with SVR both by IFN-free (P = 0.02) and by IFN-based (P < 0.001) treatments. TTR was similar in patients with SVR by IFN-free or by IFN-based (P = 0.49) strategies. CONCLUSION In HCV-infected, successfully treated patients with early HCC, SVR obtained by IFN-based or IFN-free regimens significantly reduce tumour recurrence without differences related to the anti-viral strategy used.

Abstract
Gut microbiota is characterized by an inter-individual variability due to genetic and environmental factors. Among the environmental ones, dietary habits play a key role in the modulation of gut microbiota composition. There are main differences between the intestinal microbiota of subjects fed with prevalent Western diet and that of subjects with a diet rich in fibers. Specific changes in the composition of gut microbiota have been demonstrated among subjects according to a different dietary intake. A particular diet may promote the growth of specific bacterial strains, driving hosts to a consequent alteration of fermentative metabolism, with a direct effect on intestinal pH, which can be responsible for the development of a pathogenic flora. Moreover, a high-fat diet can promote the development of a pro-inflammatory gut microbiota, with a consequent increase of intestinal permeability and, consequently, of circulating levels of lipopolysaccharides. In this review, we discuss the direct role of the diet in the composition of gut microbiota and about the possible clinical consequences.

Abstract
OBJECTIVE This is an exemplary case report underlining a relevant morbidity which could be associated to the use of autologous iliac crest bone graft (ICBG) for spine fusion. CASE REPORT Starting from 1990, a 25-years-old woman underwent two subsequent surgical treatments for non-Hodgkin lymphoma vertebral localizations. In the second surgery, arthrodesis was obtained with autograft through right posterior iliac crest osteotomy. During the chemotherapy treatment following the surgery, the patient suffered from infection at posterior iliac crest scar, the site of previous graft, caused by methicillin-resistant Staphylococcus aureus. She was subjected to surgical debridement and specific antibiotic treatment with local healing and phlogosis index reduction. Chemotherapy protocol was concluded and the patient healed with definitive lymphoma remission. After 22 years the patient had a relapse of donor site infection, requiring a new antibiotic therapy and a new surgical debridement. RESULTS The relapsed infection at donor site lasted for a long period, more than one year, despite of specific care. It finally healed after another accurate surgical debridement and postoperative antibiotic therapy. CONCLUSIONS This case report underlines the possible consequences on the patient's quality of life of a long-term disease affecting the iliac crest bone graft donor site. Literature concerning alternatives to autograft for spine fusion is also reviewed.

Abstract
OBJECTIVE Gastroenteritis represents with respiratory tract infection the most common infectious disease syndrome of humans in developing countries. Gut microbiota regional variation and dysbiosis play a crucial role in triggering and worsening this devastating GI disease. MATERIALS AND METHODS With this manuscript, we want to explore and emphasize the critical aspect of acute gastroenteritis in Middle-East Countries and its correlation with the clinical aspect of gut microbiota modification and intestinal homeostasis. RESULTS Approximately 1 of 50 children born each year in developed nations is hospitalized for acute gastroenteritis sometime during childhood. The highest rate of illness occurs in children between 3 and 24 months of age. The common causes of diarrhea are infections with viruses and bacteria, diarrhea due to a systemic infection other than gastrointestinal, diarrhea associated with antibiotic administration, and feeding related diarrhea. The single most common diarrheal disorder observed in the Emergency Department and general practice is viral gastroenteritis. In particular, Rotavirus is the cause of more than 2 million hospitalizations and over half a million deaths from acute GE in infants and young children. This burden produces also direct and indirect economic costs. The use of probiotics to counterbalance commensal dysbiosis is emerging as a standard medical practice in these countries. CONCLUSIONS In this scenario, one of the most interesting aspects is that probiotics and gut microbiota modulation could deeply improve the prevention and treatment of this devastating GI pathology. At the same time, vaccination might represent a cost-effective strategy to reduce the health and economic burden of some pathogens, such as rotavirus.

Abstract
OBJECTIVE Aneurysmal Bone Cyst (ABC) is a cystic lesion of bone, occurring in 70% of cases as a primary lesion. Even if the metaphyseal region of long bones is more frequently involved, vertebral localization is not rare: ABC represents 15% of all primary spine and sacral tumours. Selective arterial embolization (SAE) represents the first treatment option for vertebral ABC. However, in few cases, multiple SAEs are not possible. The aim of this work is to report two cases of vertebral ABC unresponsive to SAE positively treated with Denosumab. PATIENTS AND METHODS Two patients affected by ABC of the lumbar spine were treated by SAE without any response. Thus, the patients were submitted to an off-label treatment with Denosumab, following the same protocol already used in case of Giant Cell Tumour (GCT): 120 mg once a week for 4 weeks consecutively, then once every 40 days. RESULTS In both cases, patients resulted to be pain-free after 11-13 Denosumab administrations and CT scan showed almost complete ossification of the lesions. CONCLUSIONS The two cases reported here are not conclusive but they may support the project of a prospective study to confirm the effectiveness of Denosumab in ABC treatment as an alternative to SAE.

Abstract
OBJECTIVE Despite a growing interest toward the interplay between H. pylori and gastric microbiota, few data are available about this correlation. The aim of this study was to explore the relationship between H. pylori infection and gas production during lactulose breath test. MATERIALS AND METHODS Data of patients undergoing both 13C-urea breath test (UBT) and lactulose breath test (LBT) under standard conditions in our GI unit were retrospectively analyzed. GI symptoms, such as dyspepsia, bloating, abdominal pain/discomfort, and epigastric pain on an eleven-point scale were also analyzed and correlate with the results of those tests. H2 and CH4 were calculated using the trapezoidal rule; a considerable CH4 production was defined by AUCCH4 ≥1200 ppm*4h. Statistical analyses were performed with Fisher's exact test and independent samples Mann-Whitney test. RESULTS Data of 136 patients during a period of time of 3 months were analyzed. 36 patients (26.5%) showed a positive UBT. We do not find any difference as regards age, sex, symptom complaints, and small intestinal bacterial overgrowth between HP negative and positive patients. A greater methane production was observed in infected rather than non-infected patients (47.2% vs. 26% respectively, p=0.02). Furthermore, 25% infected and 10% non-infected produced greater amounts of CH4 compared to H2, resulting in a AUCCH4/AUCH2 ratio >1 (p=0.046). CONCLUSIONS This study shows for the first time, a significant association between H. pylori infection and methane production, suggesting that H. pylori might influence gut microbiota composition. Further studies are needed to clarify mechanisms underlying this phenomenon.

Abstract
OBJECTIVE To assess safety, feasibility and effectiveness of transarterial chemoembolization with degradable-starch-microspheres (DSM-TACE) in the treatment of patients with advanced hepatocellular carcinoma (HCC) dismissing or ineligible for multikinase-inhibitor chemotherapy administration (Sorafenib) due to unbearable side effects or clinical contraindications. PATIENTS AND METHODS Six consecutive advanced HCC patients dismissing Sorafenib because of unbearable side effects or worsened clinical conditions were enrolled in our prospective single-center pilot study. DSM-TACE was performed via a lobar approach, based on extent and distribution of the disease (1 treatment session for every lobe involved, with a 2-week interval in case of bilobar disease). Tumor response based on mRECIST criteria was evaluated on MD-CT performed at 1 month after "complete treatment" and every 3 months thereafter. RESULTS Eleven treatments were performed, and technical success was achieved in all patients. No intra/peri-procedural death/major complications occurred. No signs of liver failure or systemic toxicity were detected. At one month follow-up, 5 partial responses (83.3%) and 1 progression disease (16.6%) with an overall disease control (ODC) of 83.3% were observed. In two patients with ODC and residual viable tumor higher than 50%, a repeated DSM-TACE treatment was performed. During the mean follow-up of 11 months (range: 4-14 months), an ODC of 66.6% was obtained. Progression-free survival was 5.5 months with a cumulative 6-month and 1-year overall survival rates of 83.3% and 66.6%, respectively. CONCLUSIONS DSM-TACE seems to be a promising option for advanced HCC patients ineligible for Sorafenib administration or dismissing it due to progressive disease or unbearable side effects.

Abstract
A randomized, controlled, single blind study was carried out to compare the efficacy and safety of oxatomide and disodium chromoglycate in the treatment of adverse reactions to food. Twenty-three patients (16F and 7M) with urticaria (16 patients), respiratory (5 patients), intestinal (15 patients) and/or neurological symptoms (3 patients) were treated for 60 days: 14 (9F and 5M; mean ± SD age 36.3 ± 13.8 years) with oxatomide, 60 mg every evening and 9 (7F and 2M; 31.5 ± 15.1 years) with disodium chromoglycate, 500 mg three times a day. Both therapies lasted two months. On admission and after 15,30 and 60 days skin (wheals, itching, vesicular blisters, scratching lesions), respiratory (rhinorrhea, sneezing, coughing, wheezing), intestinal (constipation, diarrhea, bloating, abdominal pain and/or cramps) and neurological (headache, irritability) symptoms were assessed. Wheals decreased in number and size in both groups (p<0.005). Itching became less severe in the two groups (p<0.05), although the improvement in the oxatomide group was faster. Vesicular blisters, present in one patient in the oxatomide group at baseline, disappeared by days 15 and 30, reappearing in a mild form at the end of the study. The frequency of scratching lesions decreased. Sneezing and wheezing disappeared in both groups. Digestive system symptoms also improved. Both treatments were effective as regards cutaneous, intestinal and respiratory symptoms, with a significant reduction of itching, wheals and vesicular blisters and the complete relies of intestinal disorders. The drugs were well tolerated.

Abstract
OBJECTIVE Rickettsia conorii is responsible for the Mediterranean Spotted Fever. Recently, new rickettsial species have been recognized in Europe and implicated in human diseases. Clinical features often differ greatly from each other, but non-severe liver involvement is frequently observed during any rickettsial infection. CASE REPORT We describe the unique case of a patient presented with significant high aminotransferase levels due to the first human R. aeschlimannii infection ever detected in Italy. The hypothesis of rickettsiosis was made on the basis of a comprehensive medical history and was confirmed by serological tests. Molecular analyses made on a sample of hepatic tissue revealed the presence of a rickettsial species never found before in human liver. CONCLUSIONS A brief review of the literature is reported to highlight how relevant this case is and to remind that rickettsioses should be in the differential diagnoses of acute hepatitis, considering mostly the recent spread of new rickettsial species.

Abstract
Hepatobiliary-specific contrast agents are now widely used in magnetic resonance imaging (MRI) of liver parenchyma. As extracellular fluid agents, they provide informations regarding lesion vascularity and their use in the hepatobiliary or delayed phase (DPI), and give additional data regarding hepatocyte presence and function. The aim of this article is to review the recent literature about MRI using hepatobiliary-specific contrast agents and to discuss benefits and limits of their clinical applications. Since November 2008, hepatobiliary contrast agents were routinely employed in our Institution for the characterization of equivocal liver lesions detected by other imaging modalities, and for the evaluation of hepatic nodules in liver cirrhosis. The informations provided are particularly relevant for the detection of metastases, for the differentiation between focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA), and for the detection and differentiation between dysplastic nodules (DNs) and hepatocellular carcinoma (HCC) in the cirrhotic liver. The role in the cirrhosis grading and the quantification of liver function is still controversial. Finally, their biliary excretion allows evaluation of anatomy and function of the biliary tree. According to our and reported data, hepatobiliary contrast agents are able to improve liver lesions detection and characterization; their introduction in clinical practice has improved MRI diagnostic efficacy/accuracy, allowing to decrease the number of invasive diagnostic procedures.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) causes premature death and loss of life expectancy worldwide. Its primary and secondary prevention can result in a significant number of years of life saved. AIM To assess how many years of life are lost after HCC diagnosis. METHODS Data from 5346 patients with first HCC diagnosis were used to estimate lifespan and number of years of life lost after tumour onset, using a semi-parametric extrapolation having as reference an age-, sex- and year-of-onset-matched population derived from national life tables. RESULTS Between 1986 and 2014, HCC lead to an average of 11.5 years-of-life lost for each patient. The youngest age-quartile group (18-61 years) had the highest number of years-of-life lost, representing approximately 41% of the overall benefit obtainable from prevention. Advancements in HCC management have progressively reduced the number of years-of-life lost from 12.6 years in 1986-1999, to 10.7 in 2000-2006 and 7.4 years in 2007-2014. Currently, an HCC diagnosis when a single tumour <2 cm results in 3.7 years-of-life lost while the diagnosis when a single tumour ≥ 2 cm or 2/3 nodules still within the Milan criteria, results in 5.0 years-of-life lost, representing the loss of only approximately 5.5% and 7.2%, respectively, of the entire lifespan from birth. CONCLUSIONS Hepatocellular carcinoma occurrence results in the loss of a considerable number of years-of-life, especially for younger patients. In recent years, the increased possibility of effectively treating this tumour has improved life expectancy, thus reducing years-of-life lost.

Abstract
Mucosal healing (MH) represents a crucial factor for maintaining gut homeostasis. Indeed, in inflammatory bowel disease, MH has become the standard therapeutical target, because it is associated with more effective disease control, more frequent steroid-free remission, lower rates of hospitalization and surgery, and improved quality of life. In this scenario, gut microbiota is a crucial player in modulating intestinal repair and regeneration process. It can act on the tumor necrosis factor-α production, modulation of reactive oxygen and nitrogen species, activity of matrix metalloproteinases and on many other mechanisms strictly involved in restoring gut health. In this review, we analyze and review the literature on the role of gut microbiota in sustaining mucosal injury and achieving MH.

Abstract
BACKGROUND Hepatitis C virus (HCV) and alcohol abuse are the main risk factors for hepatocellular carcinoma (HCC) in Western countries. AIM To investigate the role of alcoholic aetiology on clinical presentation, treatment and outcome of HCC as well as on each Barcelona Clinic Liver Cancer (BCLC) stage, as compared to HCV-related HCCs. METHODS A total of 1642 HCV and 573 alcoholic patients from the Italian Liver Cancer (ITA.LI.CA) database, diagnosed with HCC between January 2000 and December 2012 were compared for age, gender, type of diagnosis, tumour burden, portal vein thrombosis (PVT), oesophageal varices, liver function tests, alpha-fetoprotein, BCLC, treatment and survival. Aetiology was tested as predictor of survival in multivariate Cox regression models and according to HCC stages. RESULTS Cirrhosis was present in 96% of cases in both groups. Alcoholic patients were younger, more likely male, with HCC diagnosed outside surveillance, in intermediate/terminal BCLC stage and had worse liver function. After adjustment for the lead-time, median (95% CI) overall survival (OS) was 27.4 months (21.5-33.2) in alcoholic and 33.6 months (30.7-36.5) in HCV patients (P = 0.021). The prognostic role of aetiology disappeared when survival was assessed in each BCLC stage and in the Cox regression multivariate models. CONCLUSIONS Alcoholic aetiology affects survival of HCC patients through its negative effects on secondary prevention and cancer presentation but not through a greater cancer aggressiveness or worse treatment result. In fact, survival adjusted for confounding factors was similar in alcoholic and HCV patients.

Abstract
OBJECTIVE Ulcerative colitis is a chronic disease that could be triggered by acute stressful events, such as gastrointestinal infections or emotional stress. PATIENTS AND METHODS We reported the case of the onset of an ulcerative colitis after a thyrotoxicosis crisis and reviewed the literature about the relationships between thyroid dysfunctions and ulcerative colitis. RESULTS A 38-year-old woman was diagnosed with ulcerative colitis after her third thyrotoxicosis crisis, two years after the diagnosis of Graves' disease. In this case, thyrotoxicosis acted as a trigger for ulcerative colitis onset. CONCLUSIONS Hyperthyroidism could be a trigger able to elicit ulcerative colitis in susceptible patients.

Abstract
Hepatitis C virus (HCV) infection is a major health problem worldwide. Chronic HCV infection may in the long run cause cirrhosis, hepatic decompensation and hepatocellular carcinoma, with an ultimate disease burden of at least 350,000 deaths per year worldwide. The new generation of highly effective direct acting antivirals (DAA) to treat HCV infection brings major promises to infected patients in terms of exceedingly high rates of sustained virological response (SVR) but also of tolerability, allowing even the sickest patients to be treated. Even in the face of the excellent safety and efficacy and wide theoretical applicability of these regimens, their introduction is currently facing cost and access issues denying their use to many patients in need. Health systems in all countries are facing a huge problem of distributive justice, since while they should guarantee individual rights, among which the right to health in its broader sense, therefore not limited to healing, but extended to quality of life, they must also grant equal access to the healthcare resources and keep the distribution system sustainable. In the face of a disease with a relatively unpredictable course, where many but not of all chronically infected will eventually die of liver disease, selective allocation of this costly resource is debatable. In most countries the favorite solution has been a stratification of patients for prioritization of treatment, which means allowing Interferon-free DAA treatment only in patients with advanced fibrosis or cirrhosis, while keeping on hold persons with lesser stages of liver disease. In this report, we will perform an ethical assessment addressing the issues linked to access to new therapies, prioritization and eligibility criteria, analyzing the meaning of the term "distributive justice" and the different approaches that can guide us (individualistic libertarianism, social utilitarianism and egalitarianism) on this specific matter. Even if over time the price of new DAA will be reduced through competition and eventual patent expiration, the phenomenon of high drug costs will go on in the next decades and we need adequate tools to face the problems of distributive justice that come with it.

Abstract
OBJECTIVE Helicobater (H.) pylori eradication rates with standard first-line triple therapy have declined to unacceptable levels. To date, amoxicillin-resistant H. pylori strains have rarely been detected. Whether increasing the dosage of amoxicillin in a standard 7 days eradicating regimen may enhance its efficacy is not known. The aim of this paper is to compare the efficacy of a 7 days high-dose amoxicillin based first-line regimen with sequential therapy. PATIENTS AND METHODS We have retrospectively analyzed data from 300 sex and age matched patients, who underwent 3 different therapeutic schemes: (1) standard LCA, lansoprazole 30 mg bid, clarithromycin 500 mg bid and amoxicillin 1000 mg bid for 7 days; (2) high dose LCA (HD-LCA), lansoprazole 30 mg bid, clarithromycin 500 mg bid and amoxicillin 1000 mg tid for 7 days; (3) sequential LACT, lansoprazole 30 mg bid plus amoxicillin 1000 mg bid for 5 days, followed by lansoprazole 30 mg bid, clarithromycin 500 mg bid and tinidazole 500 mg bid for 5 days. Eradication was confirmed by 13C-urea breath test. Compliance and occurrence of adverse effects were also assessed. RESULTS Eradication rates were: 55% for LCA, 75% for HD-LCA and 73% for LACT. Eradication rates were higher in HD-LCA group compared to LCA (p<0.01), while no significant differences were observed in HD-LCA group compared to LACT (p=ns). Compliance and occurrence of adverse effects were similar among groups. CONCLUSIONS High-dose amoxicillin based eradicating treatment is superior to standard triple therapy and equivalent to sequential therapy; compared to the latter, the shorter duration may represent an advantage.

Abstract
OBJECTIVE Iliac crest bone graft (ICBG) is considered the gold standard for spine surgical procedures to achieve a successful fusion, because of its known osteoinductive and osteoconductive properties. Considering its autogenous origin, the use of ICBG has not been associated to an increase of intraoperative or postoperative complications directly related to the surgery. However, complications related to the harvesting procedure and to the donor site morbidity have been largely reported in the literature, favoring the development of a wide range of alternative products to be used as bone graft extenders or substitutes for spine fusion. The family of ceramic-based bone grafts has been widely used and studied during the last years for spine surgical procedures in order to reduce the need for iliac crest bone grafting and the consequent morbidity associated to the harvesting procedures. PATIENTS AND METHODS We report here the results of a post-market surveillance analysis performed on four independent cohorts of patients (115 patients) to evaluate the safety of three different formulations of hydroxyapatite-derived products used as bone graft extenders/substitutes for lumbar arthrodesis. RESULTS No intraoperative or post-operative complications related to the use of hydroxyapatite-derived products were detected, during medium and long follow up period (minimum 12 months-maximum 5 years). CONCLUSIONS This post-market surveillance analysis evidenced the safety of ceramic products as bone graft extenders or substitutes for spine fusion. Moreover, the evidence of the safety of hydroxyapatite-derived products allows to perform clinical studies aimed at evaluating the fusion rates and the clinical outcomes of these materials as bone graft extenders/substitutes, in order to support their use as an alternative to ICBG for spine fusion.

Abstract
The importance of human microbiota in preserving human organism healthy is nowadays well acknowledged. The alteration of the microbiota can be the consequence of a persistent use of antibiotics or immunosuppressive medications or abdominal irradiation or surgery, wrong diet, or can be caused by surgery or anatomical condition. These alterations can cause many infections and diseases that today can be treated with Fecal Microbiota Transplantation (FMT), also called Bacteriotherapy, that is the administration of a fecal solution from a donor into the intestinal tract of a recipient. Although to date, FMT appears to be safe and without serious adverse effects, there are some ethical issues that are worthy to be investigated. The aim of this article is to highlight these issues in order to give some notes for a better implementation of this particular clinical practice.

Abstract
BACKGROUND The aim of the present study was to investigate whether microarray gene expression analysis can be used to predict lymph node status in gastric cancer. METHODS Twenty-nine patients undergoing gastrectomy for cancer were enrolled and subdivided according to the pathologic nodal involvement of their disease (N+ vs. N0). Molecular profiling was performed by cDNA microarray on tumor tissue and healthy mucosa. Data were processed to identify differently expressed genes. Selected genes were categorized with gene ontology. RESULTS Compared to healthy gastric mucosa, 52 genes were differently expressed in N+ patients, and 50 genes in N0 patients. Forty-five genes were similarly regulated in N+ and N0 patients, whereas 12 genes were differently expressed between N+ and N0 patients. Seven genes were exclusively expressed in N+ patients: Egr-1 was upregulated; Claudin-18, AKR1C2, Cathepsin E, CA II, TFF 1, and progastricsin were downregulated. Five genes were exclusively expressed in N0 patients: Complement C5 receptor 1, PLA2/VII, and MMP- 9 were upregulated; MAO-A and ID-4 were downregulated. CONCLUSIONS Microarray analysis could be a valuable tool to identify genes associated with lymph node metastasis in gastric cancer. This technique could improve the selection of patients with locally advanced disease who are candidates for extended lymph node dissection, multimodal treatment options, or alternative therapeutic strategies.

Abstract
OBJECTIVE Incidence of intrahepatic mass-forming cholangiocarcinoma (IMCC) is increasing worldwide, especially in patients with chronic liver disease. The small and the histologically well-differentiated IMCCs in chronic liver disease could be arterially hypervascular lesions with/without washout on computed tomography (CT) and magnetic resonance imaging (MRI), mimicking typical hepatocellular carcinoma (HCC). The aim of this work is to evaluate contrast enhancement (CE) patterns of IMCCs at quadri-phasic multidetector CT (4-MDCT) and MRI, using imaging-clinicopathologic correlation. PATIENTS AND METHODS The 4-MDCT and MR images of 56 histologically confirmed IMCCs were retrospectively evaluated for tumor morphology and enhancement features. Enhancement pattern was defined according to the behavior of the nodule in arterial (AP), portal venous (PVP) and equilibrium phases (EP), and dynamic pattern was described according to enhancement progression throughout the different phases. Arterial and dynamic enhancement patterns were correlated with chronic liver disease, tumor size and histological differentiation. RESULTS Most of the nodules were peripherally hyperenhancing (50%) on AP, and partially hyperenhancing on PVP (67.9%) and EP (80.3%). Forty-six (82.1%) IMCCs showed progressive CE, 7 (12.5%) stable CE and 3 (5.4%) wash-out. In normal liver there were 34 nodules with progressive and 3 with stable CE, whereas in chronic liver disease there were 12 IMCCs with progressive, 4 with stable and 3 with washout pattern (p = 0.01); IMCCs with progressive CE were more differentiated than IMCCs with stable CE and wash-out (p = 0.02). CONCLUSIONS The most prevalent enhancement pattern of IMCCs was arterial rim enhancement followed by progressive and concentric filling. The stable and the washout patterns were more frequent in poorly differentiated IMCCs. Contrast washout was observed only in IMCCs emerging in chronic liver disease with a risk of misdiagnosis with HCC.

Abstract
Previous studies established that a pocket of highly acidic gastric juice is present postprandially at the gastroesophageal junction in man. The GABA-B agonist baclofen inhibits postprandial reflux events through its effects on the lower esophageal sphincter (LES). The aim of the current study was to investigate whether baclofen would affect the location and the extent of the postprandial acid pocket in healthy volunteers. Twelve healthy volunteers underwent acid pocket studies on two different occasions, at least 1 week apart. LES position was determined preprandially with pull-through manometry. Dual pH electrode and manometry probe stepwise pull-through (1 cm/minute, LES-10 to +5 cm) was performed at 30-minute intervals for 150 minutes, with administration of placebo or baclofen 40 mg after the first and ingestion of a liquid meal after the second pull-through. After placebo, a significant drop in intragastric gastric pH was present at the gastroesophageal junction after the meal, reflecting the acid pocket, and this was associated with a drop in LES pressure. Baclofen did not affect the presence of the acid pocket, but prevented the postprandial drop in LES pressure, and the extent of the acid pocket above the upper margin of the manometrically located LES was significantly decreased by baclofen (1.6 ± 0.7 vs. 0.3 ± 0.4 cm at 60 minutes, 2.2 ± 0.6 vs. 0.2 ± 0.6 at 90 minutes, and 1.5 ± 0.5 vs. 0.7 ± 0.7 cm at 120 minutes, all P < 0.05). Baclofen does not alter the intragastric acid pocket, but limits its extension into the distal esophagus, probably through an increase in postprandial LES pressure.

Abstract
Pedicle screw and rod instrumentation has become the preferred technique for performing stabilization and fusion in the surgical treatment of lumbar spine degenerative disease. Rigid fixation leads to high fusion rates but may also contribute to stress shielding and adjacent segment degeneration. Thus, the use of semirigid rods made of polyetheretherketone (PEEK) has been proposed. Although the PEEK rods biomechanical properties, such as anterior load sharing properties, have been shown, there are few clinical studies evaluating their application in the lumbar spine surgical treatment. This study examined a retrospective cohort of patients who underwent posterior lumbar fusion for degenerative disease using PEEK rods, in order to evaluate the clinical and radiological outcomes and the incidence of complications.

Abstract
BACKGROUND Alcohol abuse represents the most common cause of liver disease in the Western countries. Pre-clinical and clinical studies showed that alcohol consumption affects amount and composition of gut microbiota. Moreover, gut flora plays an important role in the pathogenesis of alcoholic liver injury. AIM To review the relationship between alcohol administration and changes on gut microbiota, its involvement in the pathogenesis of alcoholic liver disease, and how gut microbiota modulation could be a target for the treatment of alcoholic liver disease. METHODS Articles were identified using the PubMed database with the search terms 'Alcohol', 'Gut Microbiota', 'Alcoholic liver disease', 'Probiotic', 'Prebiotic', 'Symbiotic' and 'Antibiotic'. English-language articles were screened for relevance. Full review of publications for the relevant studies was conducted, including additional publications that were identified from individual article reference lists. RESULTS Alcohol abuse induces changes in the composition of gut microbiota, although the exact mechanism for this alteration is not well known. The translocation of bacterial products into the portal blood appears to play a key role in alcohol-induced liver damage. Several studies show that the modulation of gut microbiota seem to be a promising strategy to reduce alcohol-induced liver injury. CONCLUSIONS Further studies are needed to better understand the relationship between alcohol administration and changes in gut microbiota, and its involvement in alcoholic liver disease. Moreover larger studies are needed to confirm the preliminary results on the therapeutic effects of gut microbiota modulation.

BACKGROUND Faecal microbiota transplantation (FMT) from healthy donors is considered an effective treatment against recurrent Clostridium difficile infection. AIM To study the effect of FMT via colonoscopy in patients with recurrent C. difficile infection compared to the standard vancomycin regimen. METHODS In an open-label, randomised clinical trial, we assigned subjects with recurrent C. difficile infection to receive: FMT, short regimen of vancomycin (125 mg four times a day for 3 days), followed by one or more infusions of faeces via colonoscopy; or vancomycin, vancomycin 125 mg four times daily for 10 days, followed by 125-500 mg/day every 2-3 days for at least 3 weeks. The latter treatment did not include performing colonoscopy. The primary end point was the resolution of diarrhoea related to C. difficile infection 10 weeks after the end of treatments. RESULTS The study was stopped after a 1-year interim analysis. Eighteen of the 20 patients (90%) treated by FMT exhibited resolution of C. difficile-associated diarrhoea. In FMT, five of the seven patients with pseudomembranous colitis reported a resolution of diarrhoea. Resolution of C. difficile infection occurred in 5 of the 19 (26%) patients in vancomycin (P < 0.0001). No significant adverse events were observed in either of the study groups. CONCLUSIONS Faecal microbiota transplantation using colonoscopy to infuse faeces was significantly more effective than vancomycin regimen for the treatment of recurrent C. difficile infection. The delivery of donor faeces via colonoscopy has the potential to optimise the treatment strategy in patients with pseudomembranous colitis.

Abstract
OBJECTIVE Gut barrier is a functional unit organized as a multi-layer system and its multiple functions are crucial for maintaining gut homeostasis. Numerous scientific evidences showed a significant association between gut barrier leaking and gastro-intestinal/extra-intestinal diseases. MATERIALS AND METHODS In this review we focus on the relationship between gut barrier leaking and human health. At the same time we speculate on the possible new role of gut barrier protectors in enhancing and restoring gut barrier physiology with the final goal of promoting gut health. RESULTS The alteration of the equilibrium in gut barrier leads to the passage of the luminal contents to the underlying tissues and thus into the bloodstream, resulting in the activation of the immune response and in the induction of gut inflammation. This permeability alteration is the basis for the pathogenesis of many diseases, including infectious enterocolitis, inflammatory bowel diseases, irritable bowel syndrome, small intestinal bacterial overgrowth, celiac disease, hepatic fibrosis, food intolerances and also atopic manifestations. Many drugs or compounds used in the treatment of gastrointestinal disease are able to alter the permeability of the intestinal barrier. Recent data highlighted and introduced the possibility of using gelatin tannate, a mucosal barrier protector, for an innovative approach in the management of intestinal diseases, allowing an original therapeutic orientation with the aim of enhancing mucus barrier activity and restoring gut barrier. CONCLUSIONS These results suggest how the mucus layer recovering, beside the gut microbiota modulation, exerted by gut barrier protectors could be a useful weapon to re-establish the physiological intestinal homeostasis after an acute and chronic injury.

Omega-3 fatty acids: a novel resort against gastrointestinal injury. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2014; 18:3086-3090.

Abstract
The integrity of gastric barrier derives from the balance between defending and damaging factors. In particular, prostaglandins play a relevant role in the maintenance of gastric homeostasis and prevention of peptic disease, at different levels. Omega-3 fatty acids, particularly eicosapentanoic acid, are the precursors of the third series of prostaglandins (with anti-inflammatory properties), also reducing the formation of the second series of prostaglandins (pro-inflammatory ones). Such a pathophysiological rationale brought to the experimental application, both in animal models and, more recently, in humans, of omega-3 fatty acids against gastrointestinal damage. Omega-3 fatty acids have shown interesting results in preventing different types of gastric damage in mouse models. A large retrospective case-control study on patients taking both anti-thrombotic therapy and eicosapentanoic acid showed (although only at unadjusted analysis) an inverse correlation between consumption of eicosapentanoic acid and gastrointestinal injury. Prospective, well-designed, comparative studies are warranted to clarify if omega-3 fatty acids may represent, or not, a novel resort against gastrointestinal injury.
