Accordingly, we conducted a retrospective comparative study of spontaneous peritonitis associated with fungal (SFP and fungiascites) or bacterial culture-positive ascites [spontaneous bacterial peritonitis (SBP) and bacterascites] in patients with LC.Methods: This study enrolled 73 patients with LC and ascitic culture-positive spontaneous peritonitis, including four, three, 35, and 31 patients with SFP, fungiascites, culture-positive SBP, and bacterascites, respectively. We compared the laboratory findings, Child–Pugh scores, and 1-month mortality rates between patients with fungal disease, i.e., spontaneous peritonitis associated with fungal culture-positive ascites (SFP and fungiascites), and those with bacterial disease, i.e., spontaneous peritonitis associated with bacterial culture-positive ascites (culturepositive SBP and bacterascites).Results: We observed no significant differences in the severity of underlying liver dysfunction and renal impairment between patients with fungal and bacterial disease. However, the 1-month mortality rate was significantly higher in patients with fungal disease than in those with bacterial disease (71.4%, 5/7 vs. 25.8%, 17/66; p= 0.038).Conclusion: In our retrospective study population, spontaneous peritonitis caused by fungi (SFP and fungiascites) was associated with a significantly higher short-term mortality rate compared with that of spontaneous peritonitis caused by bacteria (culture-positive SBP and bacterascites). Further studies are required to investigate the underlying mechanisms and determine the effects of antifungal therapy on mortality.","PeriodicalId":16145,"journal":{"name":"Journal of Liver","volume":"35 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85471314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pathological parameters: The 63 patients presented histological confirmation of HCC, obtained by means of a biopsy with a thick needle of 18 G or in a surgical specimen. In all of them, the histological grade of the tumor was assessed according to the WHO classification, which distinguishes 4 grades: well differentiated (BD), moderately differentiated (MD), poorly differentiated (PD) and undifferentiated.

Objectives: To assess the quality of life of hepatitis C patients receiving Sovaldi drug. To determine most common short-term side effects of Sovaldi containing regimen medication. Methods: A descriptive cross sectional study was carried out in Viral Hepatitis Treatment Center Ismailia fever Hospital. Study population was Hepatitis c virus patients treated with regimen containing sovaldi (sovaldi+ribavirin for 12 weeks). Simple random sampling was used to select the subjects included in the study Using sample size ready-made tables, 74 patients were selected to participate in this study where an interviewing questionnaire used to collect the data by 36 RAND questionnaire. Results: About 49% of the patients noticed change in their mode to the worst, and 5% felt depressed to the extent of suicide and about 61% of the patients were having difficulty with sleeping and concentrating. About half of the patients (50%) were having poor role-emotional. the most common short-term side effect were Headache which was the highest (53%) while others as(joint pain-decreasing sexual function-decreasing appetite) followed it. 35.2% were having excellent social functioning during the period of treatment of sovaldi, whereas (about 56.8%) ranging from poor to fair social functioning.

Previous studies disclosed varied results in regard to prevalence, risk factors, ascitic fluid analysis and prognosis. The objective of the present study was to ascertain prevalence and risk factors in order to have a better understanding of this complication. Methods: All orthotopic liver transplantations performed for three consecutive years were considered for inclusion. The outcome was defined as ascites that was evident on clinical examination and/or required the use of diuretics for more than 90 days after surgery. Results: The main indications for transplant were decompensated cirrhosis and hepatocellular carcinoma. Ascites persisted in 19 (13.67%) out of 139 cases. Predictive factors were portosystemic encephalopathy, portal vein thrombosis, splenomegaly, creatinine level and volume of ascites drained during surgery. On multiple regression analysis, only the amount of ascites drained during transplantation (5.05 L × 1.58 L; p<0.008) and creatinine levels less than 12 hours before transplantation (2.39 mg/dL × 1.22 mg/dL; p=0.018) remained significantly related to ascites persistence. All biochemical analysis revealed increased serum-ascites albumin gradient. Death in the first year was similar in patients with or without ascites persistence (5.6 × 4.3%) Conclusion: This study evaluated multiple potential risk factors that could contribute to long-term persistence of ascites after liver transplantation. Loss of renal function and greater volume of ascites were significantly related to persistent ascites, which was a transudate with increased serum-ascites albumin gradient. Persistent ascites was not associated with increased mortality.","PeriodicalId":16145,"journal":{"name":"Journal of Liver","volume":"24 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89069174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hepatocellular Carcinoma accounts for more than 90% of primary hepatic carcinomawith its incidence rate ranking the sixth in global tumor incidence and mortality rate ranking the third in tumor-related death in the world. Surgical resection is the preferred treatment for early primary hepatic carcinoma. It includes liver transplantation, partial hepatectomy, laparoscopic hepatectomy, etc. based on Milan criteria, University of California criteria and Hang Zhou criteria. But how the operation is done relies on tumor-evaluation in different stages before the surgery. Medical Imaging is the way to evaluate malignancy degree but is usually 2D. Even though the high-end CT and MR can reconstruct 3D image, clinicians are still provided with 2D image. Therefore, in order to diagnose diseases, surgeons have to reconstruct 2D image into 3D image in their mind according to their experience and liver anatomical structure, causing possible uncertainty and errors in the treatment [1]. It is more so in the following cases: complicated hepatectomy, which requires to resect a larger part of liver tissue, may give rise to postoperative hepatic disorder or even hepatic failure; special surgery site makes it hard to expose the anatomical position and may cause intraoperative bleeding because it is close to major vessels; hepatic blood supply disorder (hepatic congestion, hepatic ischemia) increases difficulty and risk in surgery. All of the above require clinicians to make sufficient preoperative plans, careful intraoperative anatomy and proper postoperative management [2].","PeriodicalId":16145,"journal":{"name":"Journal of Liver","volume":"357 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2017-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76923544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
