ABSTRACT
Sigmoid volvulus is a common surgical emergency, especially in elderly patients. Patients can present with a wide range of clinical states: from asymptomatic, to frank peritonitis secondary to colonic perforation. These patients generally need urgent treatment, be it endoscopic decompression of the colon or an upfront colectomy. The World Society of Emergency Surgery united a worldwide group of international experts to review the current evidence and propose a consensus guidelines on the management of sigmoid volvulus.

ABSTRACT
Background-Objectives: It has been reported, that high posthepatectomy portal vein pressure (PVP) has deleterious effect on the liver parenchyma and causes posthepatectomy liver failure (PHLF) and increased 90-day mortality. Terlipressin, is widely used to mitigate the effects of portal hyper-tension. Randomised clinical trials (RCTs) demonstrated encouraging results of use of terlipressin for modulation of increased posthepatectomy PVP. The aim of the present study was to evaluate the effectiveness of the pharmacological modulation of the increased posthepatectomy PVP after major hepatectomy. Methods: Systematic literature searches of electronic databases in accordance with PRISMA was conducted. Meta-analysis was conducted using both fixed- and random-effects models. Results: Three randomised controlled trials (RCTs) comparing terlipressin versus placebo including 284 patients of pooled 60 studies were selected. Placebo cohort patients were significantly younger by 5 years compared to terlipressin cohort. However, the terlipressin cohort demonstrated significantly shorter intensive care unit (ICU) stay compared to placebo cohort. Conclusions: The first meta-analysis demonstrated that terlipressin cohort patients although significantly older by 5 years had significantly shorter ICU stay compared to placebo cohort. Furthermore, though statistically nonsignificant only 6% of terlipressin patients needed inotropic support compared to 16.4% of placebo cohort.

The goal of non-surgical treatment is to obtain an access to the root canal system in order to remove the previous filling. We analized 45 human single-canal roots, mesial roots of mandibular molars and distal roots of maxillary molars without previous endodontic treatment, fractures, resorptive defects or open apices. We evaluated the time required to retreat root canals obturated by a new generation of GuttaCore, GuttaCore Pink®, compared to Thermafil® and Warm Vertically compacted gutta-percha, by using ProTaper® Retreatment and ProTaper® Universal. Moreover, a quantitative analysis of residual filling material in the canal after retreating and shaping was performed. The Kruskal-Wallis and Dunn's test were used to determine significant differences. Our data show that the GuttaCore Pink® can be removed from the root canal system in a lower amount of time compared to the Thermafil®. Concerning the amount of residual filling material, there are no significant differences between the three groups.
