Hepatocellular carcinoma treatment over sorafenib: epigenetics, microRNAs and microenvironment. Is there a light at the end of the tunnel?

Introduction: Sorafenib is currently the only approved therapy in hepatocellular carcinoma (HCC). Alternative first- and second-line treatments are a significant unmet medical need, and several biologic agents have been tested in recent years, with poor results. Therefore, angiogenic pathways and the cytokine cascade remain possible targets in HCC.

Short- and medium-term outcomes of laparoscopic sleeve gastrectomy: a single center experience.

There are different surgical techniques adopted to treat morbid obesity. The objective of this study is to report surgical results after 20 laparoscopic sleeve gastrectomy (LSG) cases treated for morbid obesity during a 2-year follow-up and verify the effectiveness of LSG in term of Excess Weight Loss (EWL) as compared to laparoscopic adjustable gastric banding (LAGB).

Long-term maintenance of sustained virological response in liver transplant recipients treated for recurrent hepatitis C.

Background: The recurrence of hepatitis C viral infection is common after liver transplant, and achieving a sustained virological response to antiviral treatment is desirable for reducing the risk of graft loss and improving patients' survival.

Aim: To investigate the long-term maintenance of sustained virological response in liver transplant recipients with hepatitis C recurrence.

Methods: 436 Liver transplant recipients (74.

Impact of pericardium bovine patch (Tutomesh(®)) on incisional hernia treatment in contaminated or potentially contaminated fields: retrospective comparative study.

Purpose: This retrospective comparative study analyzes the outcome of patients affected by incisional hernia in potentially contaminated or contaminated field, treated by three operative techniques.

Methods: 152 patients (62 M:90 F; mean age 65 ± 14 years) underwent incisional hernia repair (January 2002-January 2012) in complicated settings. Criteria of inclusion in the study were represented by the following causes of admission: mesh rejection/infection, obstruction without gangrene but with possible peritoneal bacterial translocation, obstruction with gangrene, enterocutaneous fistula or simultaneous presence of ileo- or colostomy.

Exhaled volatile organic compounds identify patients with colorectal cancer.

Background: An effective screening tool for colorectal cancer is still lacking. Analysis of the volatile organic compounds (VOCs) linked to cancer is a new frontier in cancer screening, as tumour growth involves several metabolic changes leading to the production of specific compounds that can be detected in exhaled breath. This study investigated whether patients with colorectal cancer have a specific VOC pattern compared with the healthy population.
