| 1 | Computed tomography findings in fatal cases of enormous hepatic portal venous gas显示文摘AIM: To assess the computed tomography (CT) findings in the patients with hepatic portal venous gas (HPVG) who presented with a short fatal clinical course in our hospital in order to demonstrate if there was any sign for prediction.METHODS: Between January 1997 and December 2000, CT scan of the abdomen was performed on 949 patients with acute abdominal pain in our emergency department.Five patients were found having HPVG. The CT images and clinical presentations of all these five patients were reviewed. RESULTS: In reviewing the CT findings of the cases, HPVG in bilateral hepatic lobes, abnormal gas in the superior mesenteric veins, small bowel intramural gas, and bowel distension were observed in all patients. Dry gas in multiple branches of the mesenteric vein was also revealed in all cases. All the patients expired due to irreversible septic shock within 48 h after their initial clinical presentation in emergency room. Two patients had acute pancreatitis with grade D and E Balthazar classification and they expired within 24 h due to progressing septic shock under aggressive medical treatment and life support. Two patients with underlying end stage renal disease expired within 48 h even though emergent surgical intervention was undertaken. The excited bowels revealed severe ischemic change. One patient expired only a few hours after the CT examination. CONCLUSION: HPVG is a diagnostic clue in patients with acute abdominal conditions, and CT is the most specific diagnostic tool for its evaluation. The dry mesenteric veins are the suggestive fatal sign, especially for the deteriorating patients, with the direct effect on gastrointestinal perfusion. | Siu-Cheung Chan Yung-Liang Wan Yun-Chung Cheung Shu-Hang Ng Alex Mun-Ching Wong Koon-Kwan Ng | 2005 | World Journal of Gastroenterology2005，11，19： | 8 |
| 2 | Is there an association between Helicobacter pylori infection and irritable bowel syndrome? A meta-analysis显示文摘BACKGROUND Irritable bowel syndrome(IBS)is a prevalent and debilitating gastrointestinal condition.Research has reported persistent,low-grade mucosal inflammation and significant overlaps between patients with IBS and those with dyspepsia,suggesting a possible pathogenic role of Helicobacter pylori(H.pylori)in IBS.This study therefore aimed to provide the first systematic review and meta-analysis on the association between H.pylori infection and IBS.AIM To investigate the association between H.pylori infection and IBS.METHODS Using the keywords“H.pylori OR Helicobacter OR Helicobacter pylori OR infection”AND“irritable bowel syndrome OR IBS”,a preliminary search of PubMed,Medline,Embase,Cochrane Database of Systematic Reviews,Web of Science,Google Scholar and WanFang databases yielded 2924 papers published in English between 1 January 1960 and 1 June 2018.Attempts were also made to search grey literature.RESULTS A total of 13 clinical studies were systematically reviewed and nine studies were included in the final meta-analysis.Random-effects meta-analysis found a slight increased likelihood of H.pylori infection in patients with IBS,albeit this was not statistically significant(pooled odds ratio 1.47,95%confidence interval:0.90-2.40,P=0.123).It must also be acknowledged that all of the available studies reported only crude odd ratios.H.pylori eradication therapy also does not appear to improve IBS symptoms.Although publication bias was not observed in the funnel plot,there was a high degree of heterogeneity amongst the studies included in the meta-analysis(I2=87.38%).CONCLUSION Overall,current evidence does not support an association between IBS and H.pylori infection.Further rigorous and detailed studies with larger sample sizes and after H.pylori eradication therapy are warranted. | Qin Xiang Ng Nadine Xinhui Foo Wayren Loke Yun Qing Koh Vanessa Jing Min Seah Alex Yu Sen Soh Wee Song Yeo | 2019 | World Journal of Gastroenterology2019，25，37： | 5 |
| 3 | Imaging of the anterior cruciate ligament显示文摘The anterior cruciate ligament(ACL)is an important structure in maintaining the normal biomechanics of the knee and is the most commonly injured knee ligament.However,the oblique course of the ACL within the intercondylar fossa limits the visualization and assessment of the pathology of the ligament.This pictorial essay provides a comprehensive and illustrative review of the anatomy and biomechanics as well as updated information on different modalities of radiological investigation of ACL,particularly magnetic resonance imaging. | Wing Hung Alex Ng James Francis Griffith Esther Hiu Yee Hung Bhawan Paunipagar Billy Kan Yip Law Patrick Shu Hang Yung | 2011 | World Journal of Orthopedics2011，2，8： | 4 |
| 4 | Escitalopram-induced liver injury: A case report and review of literature显示文摘BACKGROUND Depression is a growing public health problem that affects over 350 million people globally and accounts for approximately 7.5%of healthy years lost due to disability.Escitalopram,one of the first-line medications for the treatment of depression,is a selective serotonin reuptake inhibitor and one of the most commonly prescribed antidepressant medications worldwide.Although thought to be generally safe and with minimal drug-drug interactions,we herein present an unusual case of cholestatic liver injury,likely secondary to escitalopram initiation.CASE SUMMARY A 56-year-old Chinese lady presented with fever and cholestatic liver injury two weeks after initiation of escitalopram for the treatment of psychotic depression.Physical examination was unremarkable.Further investigations,including a computed tomography scan of the abdomen and pelvis and tests for hepatitis A,B and C and for autoimmune liver disease were unyielding.Hence,a diagnosis of escitalopram-induced liver injury was made.Upon stopping escitalopram,repeat liver function tests showed downtrending liver enzymes with eventual normalization of serum aspartate aminotransferase and alanine aminotransferase one-week post-discharge.CONCLUSION Clinicians should be aware of the possibility of escitalopram-induced liver injury when initiating depressed patients on antidepressant treatment.This requires extra vigilance as most patients may remain asymptomatic.Measurement of liver function tests could be considered after initiation of antidepressant treatment,especially in patients with pre-existing liver disease. | Qin Xiang Ng Christl Suet Kwan Yong Wayren Loke Wee Song Yeo Alex Yu Sen Soh | 2019 | World Journal of Hepatology2019，11，10： | 3 |

| 16 | Monitoring of ground deformation in Liulin district,China using InSAR approaches显示文摘Coalbed methane(CBM)exploration generally refers to a technique that extracts natural gas from coal beds.The development of CBM in Liulin,China,has experienced a significantly growth period during the past two decades.Previous research mainly focused on the coal geological background or CBM technique itself,while time series InSAR(TS-InSAR)technique was conducted in this work to study the potential land deformation induced by CBM extraction from 2003 to 2011.In total,21 ALOS-1 PALSAR images(acquired from 22 December 2006 to 2 January 2011)and 14 ENVISAT ASAR scenes(captured between 29 October 2003 and 7 November 2007)were used.The TS-InSAR outcome revealed that the annual deformation rates were ranging from 15 to−40 mm yr−1 over the study region.Then the time series deformation evolutions were analysed over 8 CBM sites(No.4 coal seam)out of 20,and the subsidence rates between 1.9 and−6.5 mm yr−1 were derived.In addition,the average subsidence rate and standard deviation among these eight measurements were−3.0 and 2.6 mm yr−1 respectively,suggesting that these CBM extraction sites were quite stable and no obvious subsidence had been observed during this eight-year period. | Zheyuan Du Linlin Ge Alex Hay-Man Ng Xiaojing Li Liyuan Li | 2018 | International Journal of Digital Earth2018，11，3： | 1 |

| 19 | Prenatal diagnosis of choledochal cyst using magnetic resonance imaging: A case report显示文摘Choledochal cysts are congenital anomalies of the biliary ducts, characterized by cystic dilatation of the ducts.Prenatal diagnosis of this anomaly using ultrasonography (US) has been well documented. Magnetic resonance imaging (MRI) has recently become an important complement to US in prenatal diagnosis of fetal anomalies. We herein report a patient in whom at 24 wk' gestation US suggested a right upper quadrant abdominal cyst and in whom at 26 wk' gestation MRI more clearly delineated the cyst and its surrounding structures and suggested a choledochal cyst, which was confirmed at postnatal surgery and histopathology. | Alex Mun-Ching Wong Yun-Chung Cheung Yu-Hung Liu Koon-Kwan Ng Siu-Cheung Chan Shu-Hang Ng | 2005 | World Journal of Gastroenterology2005，11，32： | 1 |
