fecal peritonitis due to colorectal perforation is a dramatic event characterized by high mortality. Our study aims at determining how results of sigmoid resection (eventually extended to upper rectum) for colorectal perforation with fecal peritonitis changed in recent years and which factors affected eventual changes.Seventy-four patients were operated on at our institution (2005-2014) for colorectal perforation with fecal peritonitis and were divided into two numerically equal groups (operated on before (ERA1-group) and after (ERA2-group) May 2010). Mannheim Peritonitis Index (MPI) was calculated for each patient. Characteristics of two groups were compared. Predictors of postoperative outcomes were identified.Postoperative overall complications, major complications, and mortality occurred in 59%, 28%, and 18% of cases, respectively, and were less frequent in ERA2-group (51%, 16%, and 8%, respectively), compared to ERA1-group (68%, 41%, and 27%, respectively; p = .155, .02, and .032, respectively). Such results paralleled lower MPI values in ERA2-group, compared to ERA1-group (23(16-39) vs. 28(21-43), p = .006). Using receiver operating characteristic analysis, the best cut-off value for MPI for predicting postoperative complications and mortality was 28.5. MPI28 was the only independent predictor of postoperative overall (p = .009, OR = 4.491) and major complications (p .001, OR = 23.182) and was independently associated with a higher risk of mortality (p = .016, OR = 13.444), as well as duration of preoperative peritonitis longer than 24 h (p = .045, OR = 17.099).results of surgery for colorectal perforation with fecal peritonitis have improved over time, matching a concurrent decrease of MPI values and a better preoperative patient management. MPI value may help in selecting patients benefitting from surgical treatment.

Gamma-hydroxybutyric acid (GHB) is used to treat alcohol withdrawal syndrome (AWS) at short term, and to reduce alcohol relapses among alcohol dependent subjects at mid-term. The objective of this paper is to synthesize results of a Cochrane review on efficacy of GHB for treating alcohol dependence at mid-term.The search strategy was conducted on MEDLINE, EMBASE, PsycINFO, CINAHL and on the Cochrane Library. Pharmaceutical companies were contacted and references of papers were checked in order to identify unpublished studies. Randomized controlled trials (RCT), clinical controlled trials (CCT), and controlled prospective studies (CPS) were considered. Three authors blindly evaluated the quality of the studies and extracted the data.Seven RCT studies evaluating efficacy of GHB for treating alcohol dependence at mid-term were included in the review; all were conducted in Italy. GHB appears to be more effective than placebo on alcohol abstinence (RR 2.63; 1.22-5.71), controlled drinking (RR 2.43; 1.07-5.54), relapses to heavy drinking (RR 0.37; 0.21-0.63), and number of daily drinks (MD -4.60; -6.18,-3.02). GHB appears to be more effective than naltrexone on alcohol abstinence (RR 1.78; 1.21-2.62) but not on other outcomes. The effect on Alcohol Craving Scale favours GHB vs placebo (MD -4.50; -5.81,-3.19), vs naltrexone (MD -1.90; -2.45,-1.35) and vs disulfiram (MD -1.40; -1.86,-0.94). Side effects are similar to naltrexone and disulfiram.The low number of available studies, the low sample size and the low quality of the included studies limit the validity of the results and suggest the need of conducting new high-quality randomized trials with appropriate sample size.
