| 1 | Post-endoscopic retrograde cholangiopancreatography pancreatitis: Risk factors and predictors of severity显示文摘AIM To detect risk factors for post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) and investigate the predictors of its severity.METHODS This is a prospective cohort study of all patients who underwent ERCP.Pre-ERCP data,intraoperative data,and post-ERCP data were collected.RESULTS The study population consisted of 996 patients.Their mean age at presentation was 58.42(± 14.72) years,and there were 454 male and 442 female patients.Overall,PEP occurred in 102(10.2%) patients of the study population; eighty(78.4%) cases were of mild to moderate degree,while severe pancreatitis occurred in 22(21.6%) patients.No hospital mortality was reported for any of PEP patients during the study duration.Age less than 35 years(P = 0.001,OR = 0.035),narrower common bile duct(CBD) diameter(P = 0.0001) and increased number of pancreatic cannulations(P = 0.0001) were independent risk factors for the occurrence of PEP.CONCLUSION PEP is the most frequent and devastating complication after ERCP.Age less than 35 years,narrower median CBD diameter and increased number of pancreaticcannulations are independent risk factors for the occurrence of PEP.Patients with these risk factors are candidates for prophylactic and preventive measures against PEP. | Ayman El Nakeeb Ehab El Hanafy Tarek Salah Ehab Atef Hosam Hamed Ahmad M Sultan Emad Hamdy Mohamed Said Ahmed A El Geidie Tharwat Kandil Mohamed El Shobari Gamal El Ebidy | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，19： | 10 |
| 2 | HepG2 cells support viral replication and gene expression of hepatitis C virus genotype 4 in vitro显示文摘瞄准:与丙肝的长期的复制建立一个房间文化系统病毒(HCV ) 染色体和病毒的抗原的表示在试管内。方法:HepG2 房间线被孵化与长期的丙肝从一个病人与浆液为它的危险性测试到 HCV。房间和上层清液在文化期间在各种各样的时间点被收获。文化上层清液为它感染天真的房间的能力被测试。存在减(反感觉) 在房间的核心和 E1 抗原的 RNA 海滨,和察觉被 RT-PCR 和免疫学的技术(流动血细胞计数和西方的污点) 分别地检验。结果:细胞内部的 HCV RNA 首先在 d 上被检测 3 在感染以后然后能一致地在至少三个月的一个时期上在房间和上层清液被检测。新鲜房间能从有教养的感染的房间感染上层清液。流动 cytometric 分析证明表面和在房子里使用的细胞内部的 HCV 抗原表示使 polyclonal 成为了抗体(反核心,和 anti-E1 ) 。西方的污点分析证明在分子量的产生免疫性的肽的簇的表示在一个月内在 31 和 45 kDa 之间延长了感染的房间的旧文化而这簇在 uninfected HepG2 房间是无法发现的。结论:HepG2 房间线产生 HCV 感染而且支持它的复制在试管内不仅。HCV 结构的蛋白质的表示能在感染的 HepG2 房间被检测。这些房间也能够流病毒的粒子进接着对 uninfected 房间变得传染的培养基。 | Mostafa K El-Awady Ashraf A Tabll Yasmine S El-Abd Mahmoud M Bahgat Hussein A Shoeb Samar S Youssef Noha G Bader El Din El-Rashdy M Redwan Maha El-Demellawy Moataza H Omran Wael T El-Garf Said A Goueli | 2006 | World Journal of Gastroenterology2006，12，30： | 2 |
| 3 | Effectiveness of hepatitis B virus vaccination program in Egypt:Multicenter national project显示文摘AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated children.METHODS:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to < 10,10 to < 15 and ≥ 15 years respectively compared to those < 5 years and 1.1 among girls compared to boys with P < 0.01. HBs Ag was positive in 0.11% and breakthrough infection was 0.36% and 0.39% depending on positivity of anti-HBc and DNA detection respectively. The prevalence of HBV infection was significantly higher among children aged ≥ 7 years(0.59%) compared to 0.07% among younger children with odds ratio equal to 8.4(95%CI:1.1-64.2) and P < 0.01.The prevalence was higher among girls(0.48%) than boys(0.29%) with P > 0.05. C ON C LU S I ON :T he E gy pt ian c ompuls or y H B V vaccination program provides adequate protection. Occult HBV infection exists among apparently healthy vaccinated children. Adherence to infection control measures is mandatory. | Iman I Salama Samia M Sami Zeinab Nabil Ahmed Said Manal H El-Sayed Lobna A El Etreby Thanaa M Rabah Dalia M Elmosalami Amany T Abdel Hamid Somaia I Salama Aida M Abdel Mohsen Hanaa M Emam Safaa M Elserougy Amal I Hassanain Naglaa F Abd Alhalim Fatma A Shaaban Samia A Hemeda Nihad A Ibrahim Ammal M Metwally | 2015 | World Journal of Hepatology2015，7，22： | 2 |
