Important progress has been made in the management of Helicobacter pylori infection and in this fifth edition of the Maastricht Consensus Report, key aspects related to the clinical role of H. Pylori were re-evaluated in 2015. In the Maastricht V/Florence Consensus Conference, 43 experts from 24 countries examined new data related to H. pylori in five subdivided workshops: (1) Indications/ Associations, (2) Diagnosis, (3) Treatment, (4) Prevention/Public Health, (5) H. pylori and the Gastric Microbiota. The results of the individual workshops were presented to a final consensus voting that included all participants. Recommendations are provided on the basis of the best available evidence and relevance to the management of H. pylori infection in the various clinical scenarios.

Background & Aims: Transcatheter arterial chemoembolization (TACE) currently is used as a palliative treatment for patients with unresectable hepatocellular carcinoma (HCC), but its efficacy still is debated. Our aim was to assess the impact of TACE on patient survival and to identify prognostic factors for survival. Methods: Fifty-six cirrhotic patients with unresectable HCC undergoing at least :1 course of TACE were matched 1:1. for sex, age (in 5-year periods), parameters of Child-Pugh score, Okuda stage, and tumor type with a control group who had received only supportive care. Results: The 2 groups were comparable for cause of cirrhosis, alpha-fetoprotein serum levels, and Cancer of the Liver Italian Program (CLIP) score. The 56 patients in the TACE group received a total of 123 treatment courses. The median follow-up period was 16 months (range, 1-67 mo) in the TACE group and 5 months (range, 1-77 mo) in the supportive care group. Survival rates at 12, 24, and 30 months in patients receiving TACE were 74.3%, 52.1%, and 38.8% respectively, with a median survival time of 25 month whereas in supportive care patients the rates we 39.4%, 25.4%, and 19%, respectively, with a median survival time of 7 months (P =.0004). At univariate analysis, TACE, tumor type, presence of ascites, alpha-fetoprotein serum level, CLIP score, and Okuda stage were associated significantly with survival. Only TACE and CLIP score proved to be independent predictors of survival at multivariate analysis. Conclusions: TACE is an effective therapeutic option for cirrhotic patients with unresectable HCC and a CLIP score of 3 or less.

Objective. Celiac disease (CD) has strongly been established as associated with some site-specific gastrointestinal malignancies. On the contrary, according to the few reports available, the risk of colon carcinoma in CD patients has been described similar to that of general population. In this cohort study, we describe the risk of colon carcinoma in a group of Italian celiac patients. Materials and methods. The study population included all CD patients diagnosed at the Collaborating Centers of the Italian Registry of CD between 1st January 1982 and 31st December 2006. Upon diagnosis of CD and upon at every subsequent clinical control, the Collaborating Centers filled in a validated form for each CD patient reporting information about demographic data, possible occurrence of a neoplasm and adherence to a gluten-free diet. Results. Out of 1757 celiac patients enrolled, 6 developed a colon carcinoma during the follow-up period (mean: 18.1 years). The standardized incidence ratio (SIR) resulted 0.29 (95% CI = 0.07–0.45). Stratifying the risk for the dietary gluten intake, the SIR dropped to 0.07 (95% CI = 0.009–0.27) for CD patients with a strict adherence to a gluten-free diet. Conclusion. We confirm the previous finding that there is low risk to develop a colon cancer in celiac patients.

Background. Ascites is one of the most frequent severe complications in patients with liver cirrhosis. The treatment of this chronic disease usually requires the prolonged use of albumin, frequently continued even after patients' discharge from the hospital. Aims. Aim of the study was to define a consensus among Italian physicians with regard to the use of albumin in patients with decompensated cirrhosis and ascites. Methods. The study adopted the Delphi technique to conduct the consensus activities. All controversial issues related to the use of albumin were identified by the experts' board and proposed to the 68 participating hepatology centres through two subsequent questionnaires. The questionnaires, returned by the specialists involved, were collected and the answers classified to verify the elements on which a consensus was reached. Results. The home use of albumin can help to improve the patient's general conditions and well-being. About 77% of the experts involved considered likely that albumin administration could shorten hospital stays or could reduce the number of hospital admissions. The results of the study, along with a socioeconomic analysis, were presented to the Italian Drug Commission, which subsequently removed the specific hypoalbuminemia level as a prerequisite for having the drug reimbursed by the National Health Service. Conclusions. For an outpatient prescription, the hypoalbuminemia limit of 2.5 g/dl or less is not sufficient, while the decision whether to administer the drug requires the evaluation of patient's overall clinical conditions as an essential criterion for the prescription of a home treatment with albumin.

L’abuso cronico di alcol rappresenta un problema sociale ed una patologia relativamente frequente nei Paesi occidentali. L’uso inadeguato di alcol rappresenta la causa di circa il 4% di tutte le patologie. Tra le patologie alcol-correlate, l’alcol-dipendenza (altresì definita alcolismo) costituisce il problema più severo ed interessa approssimativamente il 14% della popolazione generale. Ma tale percentuale tende a salire se si considerano anche altre forme di consumo patologico di alcol, quali l’abuso alcolico ed il fenomeno sempre più frequente dello heavy drinking. L’Italia rimane una delle Nazioni ad alto consumo di bevande alcoliche e si stima che l’abuso possa interessare 5 milioni di persone, valutabile attorno ai 4 milioni di individui, definiti come “bevitori eccessivi” e che di questi circa 1 milione sono identificabili come “alcoldipendenti”. La mortalità alcol-correlata, che comprende, oltre alla mortalità per patologie croniche degenerative e neoplastiche, anche la quota derivante da incidenti stradali, omicidi e suicidi, viene quantificata in Italia in circa 30.000 ecessi/anno; inoltre è lecito avanzare l’ipotesi che si tratti di una sottostima se si considera che una notevole quota di cause, con particolare riferimento alle malattie neoplastiche, sfugge alla correlazione con l’abuso etilico.

Background: Traditionally, pneumonia has been classified as either community- or hospital-acquired. Although only limited data are available, health care–associated pneumonia has been recently proposed as a new category of respiratory infection. “Health care–associated pneumonia” refers to pneumonia in patients who have recently been hospitalized, had hemodialysis, or received intravenous chemotherapy or reside in a nursing home or long-term care facility. Objective: To ascertain the epidemiology and outcome of community-acquired, health care–associated, and hospital-acquired pneumonia in adults hospitalized in internal medicine wards. Design: Multicenter, prospective observational study. Setting: 55 hospitals in Italy comprising 1941 beds. Patients: 362 patients hospitalized with pneumonia during two 1-week surveillance periods. Measurements: Cases of radiologically and clinically assessed pneumonia were classified as community-acquired, health care–associated, or hospital-acquired and rates were compared. Results: Of the 362 patients, 61.6% had community-acquired pneumonia, 24.9% had health care–associated pneumonia, and 13.5% had hospital-acquired pneumonia. Patients with health care–associated pneumonia had higher mean Sequential Organ Failure Assessment scores than did those with community-acquired pneumonia (3.0 vs. 2.0), were more frequently malnourished (11.1% vs. 4.5%, and had more frequent bilateral (34.4% vs. 19.7%) and multilobar (27.8% vs. 21.5%) involvement on a chest radiograph. Patients with health care–associated pneumonia also had higher fatality rates (17.8% [CI, 10.6% to 24.9%] vs. 6.7% [CI, 2.9% to 10.5%]) and longer mean hospital stay (18.7 days [CI, 15.9 to 21.5 days] vs. 14.7 days [CI, 13.4 to 15.9 days]). Logistic regression analysis revealed that depression of consciousness (odds ratio [OR], 3.2 [CI, 1.06 to 9.8]), leukopenia (OR, 6.2 [CI, 1.01 to 37.6]), and receipt of empirical antibiotic therapy not recommended by international guidelines (OR, 6.4 [CI, 2.3 to 17.6]) were independently associated with increased intrahospital mortality. Limitations: The number of patients with health care–associated pneumonia was relatively small. Microbiological investigations were not always homogeneous. The study included only patients with pneumonia that required hospitalization; results may not apply to patients treated as outpatients. Conclusion: Health care–associated pneumonia should be considered a distinct subset of pneumonia associated with more severe disease, longer hospital stay, and higher mortality rates. Physicians should differentiate between patients with health care–associated pneumonia and those with community-acquired pneumonia and provide more appropriate initial antibiotic therapy.

Patients with celiac disease have an increased rate of enteropathy-associated T-cell lymphoma, but conflicting data are available about the protective role of a gluten-free diet with regard to the development of this malignancy. We followed 1,757 celiac patients for a total period of 31,801 person-years, collecting data about the frequency of gluten intake and the incidence of the enteropathy-associated T-cell lymphoma. Out of the nine celiac patients who developed an intestinal lymphoma [standard morbidity ratio of 6.42 (95% CI = 2.9-12.2; P < 0.001)], only two kept a strict gluten-free diet after the diagnosis of celiac disease and developed the malignancy after the peridiagnosis period of 3 years, dropping therefore the standard morbidity ratio to 0.22 (95%CI = 0.02-0.88; P < 0.001). The risk of developing an intestinal lymphoma for the celiac patients that used to have dietary gluten was significant (X(2 )= 4.8 P = 0.01). These results show that a strict gluten-free diet is protective towards the development of enteropathy-associated T-cell lymphoma.

Background The association between coeliac disease (CD) and neoplasms has been long established, but few data are available about the risk factors. The aim of this paper is to estimate the risk of developing a neoplasm among non diagnosed coeliac patients and to evaluate if this risk correlates with the age of patients at diagnosis of coeliac disease. Methods The study population consists of patients (n = 1968) diagnosed with CD at 20 Italian gastroenterology referral Centers between 1st January 1982 and 31st March 2005. Results The SIR for all cancers resulted to be 1.3; 95% CI = 1.0–1.7 p < 0.001. The specific SIRs for non Hodgkin lymphoma was 4.7; 95% CI = 2.9–7.3 p < 0.001, for the small bowel carcinoma 25; 95% CI = 8.5–51.4 p < 0.001, for non Hodgkin lymphoma 10; 95% CI = 2.7–25 p = 0.01, finally for the stomach carcinoma 3; 95% CI = 1.3–4.9 p < 0.08. The mean age at diagnosis of CD of patients that developed sooner or later a neoplasm was 47,6 ± 10.2 years versus 28.6 ± 18.2 years of patients who did not. Conclusion Coeliac patients have an increased risk of developing cancer in relation to the age of diagnosis of CD. This risk results higher for malignancies of the gastro-intestinal sites. An accurate screening for tumors should be performed in patients diagnosed with CD in adulthood and in advancing age.

This study was designed to evaluate physiological and psychological stress parameters in 2 professional trained scuba divers, using a unique physiopathologic model, offered by the guinness 240 hours scuba dive. Two scuba dive masters have spent 240 hours at 6 - 8 meters depth (26.4 ft) in Ponza Island water (Italy). Blood samples were collected daily in the underwater bell; samples were carried out of water in waterproof bags. Breath samples were collected, measuring ethylene release. Psychological assessment was performed using the State and Trait Anxiety Inventory and the Zung self-rating depression scale. In the studied subjects, cortisol and prolactin showed physiological pulsatile secretion. Breath ethylene didn't exceed normal values. At the start of the study, no subjects showed high levels of state anxiety, trait anxiety and current depression. Psychometric scales scores remained steady during the diving period and no subjects showed anxiety and/or depression and/or panic symptoms during the time of observation. The present study shows that, although the long-time diving, well trained professional divers did not develop anxiety and/or depression. No subject discontinued the diving due to occurred psychological disorders or systemic events. The present report shows that the long-term diving permanence is possible, at least in well trained scuba divers.
