2Treatment options for alcoholic and non-alcoholic fatty liver disease: A review显示文摘Alcoholic liver disease(ALD)and non-alcoholic fatty liver disease(NAFLD)are serious health problems worldwide.These two diseases have similar pathological spectra,ranging from simple steatosis to hepatitis to cirrhosis and hepatocellular carcinoma.Although most people with excessive alcohol or calorie intake display abnormal fat accumulation in the liver(simple steatosis),a small percentage develops progressive liver disease.Despite extensive research on understanding the pathophysiology of both these diseases there are still no targeted therapies available.The treatment for ALD remains as it was 50 years ago:abstinence,nutritional support and corticosteroids(or pentoxifylline as an alternative if steroids are contraindicated).As for NAFLD,the treatment modality is mainly directed toward weight loss and co-morbidity management.Therefore,new pathophysiology directed therapies are urgently needed.However,the involvement of several inter-related pathways in the pathogenesis of these diseases suggests that a single therapeutic agent is unlikely to be an effective treatment strategy.Hence,a combination therapy towards multiple targets would eventually be required.In this review,we delineate the treatment options in ALD and NAFLD,including various new targeted therapies that are currently under investigation.We hope that soon we will be having an effective multi-therapeutic regimen for each disease.Sukhpreet Singh Natalia A Osna Kusum K Kharbanda 2017World Journal of Gastroenterology2017,23,36:45
3Omental flaps reduces complications after pancreaticoduodenectomy显示文摘BACKGROUND:Major complications after pancreaticoduodenectomy are usually caused by a leaking pancreaticojejunal anastomosis.Omental flaps around various anastomoses were used to prevent the formation of fistula.METHODS:We reviewed 147 patients who had undergone pancreaticoduodenectomy between March 2006 and March2012.The patients were divided into 2 groups according to the application of omental flaps around various anastomoses:group A(101 patients)who underwent omental wrapping procedure;group B(46 patients)who did not undergo the omental wrapping procedure.Perioperative data of the two groups were reviewed to assess the effectiveness of omental flap procedure in the prevention of pancreatic fistula and other complications.RESULTS:No differences were observed in the clinical characteristics between the 2 groups.The incidences of pancreatic fistula(4.0%vs 17.4%),post-pancreatectomy hemorrhage(0vs 6.5%),biliary fistula(1.0%vs 13.0%),and delayed gastric emptying(4.0%vs 17.4%)were significantly less frequent in group A.The overall morbidity(18.8%vs 47.8%)and hospital stay(8.3 vs 9.6 days)were also significantly lower in group A than in group B.CONCLUSIONS:Omental flaps around various anastomoses after pancreaticoduodenectomy can reduce the incidences of pancreatic fistula,biliary fistula,post-pancreatectomy hemorrhage and delayed gastric emptying.This procedure is simple and effective to reduce the overall morbidity after pancreaticoduodenectomy.Omar J Shah Sadaf A Bangri Manmohan Singh Reyaz A Lattoo Mohammad Y Bhat 2015Hepatobiliary & Pancreatic Diseases International2015,14,3:19
4Endoscopic ultrasound:It’s accuracy in evaluating mediastinal lymphadenopathy? A meta-analysis and systematic review显示文摘AIM:To evaluate the accuracy of endoscopic ultrasound (EUS), EUS-fine needle aspiration (FNA) in evaluating mediastinal lymphadenopathy. METHODS:Only EUS and EUS-FNA studies confirmed by surgery or with appropriate follow-up were selected. Articles were searched in Medline, Pubmed, and Cochrane control trial registry. Only studies from which a 2 × 2 table could be constructed for true positive, false negative, false positive and true negative values were included. Two reviewers independently searched and extracted data. The differences were resolved by mutual agreement. Meta-analysis for the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and diagnostic odds ratios. Pooling was conducted by both Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran’s Q test based upon inverse variance weights. RESULTS:Data was extracted from 76 studies (n = 9310) which met the inclusion criteria. Of these, 44 studies used EUS alone and 32 studies used EUS-FNA. FNA improved the sensitivity of EUS from 84.7% (95% CI:82.9-86.4) to 88.0% (95% CI:85.8-90.0). With FNA, the specificity of EUS improved from 84.6% (95% CI:83.2-85.9) to 96.4% (95% CI:95.3-97.4). The P forchi-squared heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION:EUS is highly sensitive and specific for the evaluation of mediastinal lymphadenopathy and FNA substantially improves this. EUS with FNA should be the diagnostic test of choice for evaluating mediastinal lymphadenopathy.Srinivas R Puli Jyotsna Batapati Krishna Reddy Matthew L Bechtold Jamal A Ibdah Daphne Antillon Shailender Singh Mojtaba Olyaee Mainor R Antillon 2008World Journal of Gastroenterology2008,14,19:10

6Alcoholic pancreatitis:New insights into the pathogenesisand treatment显示文摘Acute pancreatitis is a necro-inflammatory disease of the exocrine pancreas that is characterized by inappropriate activation of zymogens, infiltration of the pancreas by inflammatory cells, and destruction of the pancreatic exocrine cells. Acute pancreatitis can progress to a severe life-threatening disease. Currently there is no pharmacotherapy to prevent or treat acute pancreatitis. One of the more common factors associated with acute pancreatitis is alcohol abuse. Although commonly associated with pancreatitis alcohol alone is unable to cause pancreatitis. Instead, it appears that alcohol and its metabolic by-products predispose the pancreas to damage from agents that normally do not cause pancreatitis, or to more severe disease from agents that normally cause mild pancreatic damage. Over the last 10 to 20 years, a tremendous amount of work has defined a number of alcohol-mediated biochemical changes in pancreatic cells. Among these changes are: Sustained levels of intracellular calcium, activation of the mitochondrial permeability transition pore, endoplasmic reticulum stress, impairment in autophagy, alteration in the activity of transcriptional activators, and colocalization of lysosomal and pancreatic digestive enzymes. Elucidation of these changes has led to a deeper understanding of the mechanisms by which ethanol predisposes acinar cells to damage. This greater understanding has revealed a number of promising targets for therapeutic intervention. It is hoped that further investigation of these targets will lead to the development of pharmacotherapy that is effective in treating and preventing the progression of acute pancreatitis.Dahn L Clemens Katrina J Schneider Christopher K Arkfeld Jaclyn R Grode Mark A Wells Shailender Singh 2016World Journal of Gastrointestinal Pathophysiology2016,7,1:10
7Stereotactic body radiation therapy for non-small cell lung cancer:A review显示文摘Stereotactic body radiation therapy(SBRT) is the treatment of choice for medically inoperable patients with early stage non-small cell lung cancer(NSCLC). A literature search primarily based on PubMed electronic databases was completed in July 2018. Inclusion and exclusion criteria were determined prior to the search, and only prospective clinical trials were included. Nineteen trials from 2005 to 2018 met the inclusion criteria, reporting the outcomes of 1434 patients with central and peripheral early stage NSCLC. Patient eligibility,prescription dose and delivery, and follow up duration varied widely. Threeyears overall survival ranged from 43% to 95% with loco-regional control of up to 98% at 3 years. Up to 33% of patients failed distantly after SBRT at 3 years. SBRT was generally well tolerated with 10%-30% grade 3-4 toxicities and a few treatment-related deaths. No differences in outcomes were observed between conventionally fractionated radiation therapy and SBRT, central and peripheral lung tumors, or inoperable and operable patients. SBRT remains a reasonable treatment option for medically inoperable and select operable patients with early stage NSCLC. SBRT has shown excellent local and regional control with toxicity rates equivalent to surgery. Decreasing fractionation schedules have been consistently shown to be both safe and effective. Distant failure is common, and chemotherapy may be considered for select patients. However, the survival benefit of additional interventions, such as chemotherapy, for early stage NSCLC treated with SBRT remains unclear.Kavitha M Prezzano Sung Jun Ma Gregory M Hermann Charlotte I Rivers Jorge A Gomez-Suescun Anurag K Singh 2019World Journal of Clinical Oncology2019,10,1:10

10急性脊髓损伤患者治疗的临床操作指南:关于MRI基线在临床治疗决策与结果预测中作用的几点建议(英文)显示文摘The objective of this guideline is to outline the role of magnetic resonance imaging(MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury(SCI).Methods A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic SCI.This review focused on longitudinal studies that controlled for baseline neurologic status.A multidisciplinary Guideline Development Group(GDG) used this information,their clinical expertise,and patient input to develop recommendations on the use of MRI for SCI patients.Based on GRADE(Grading of Recommendation,Assessment,Development and Evaluation),a strong recommendation is worded as ' we recommend,' whereas a weaker recommendation is indicated by 'we suggest.' Results Based on the limited available evidence and the clinical expertise of the GDG,our recommendations were:(1) 'We suggest that MRI be performed in adult patients with acute SCI prior to surgical intervention,when feasible,to facilitate improved clinical decision-making'(quality of evidence,very low) and(2) 'We suggest that MRI should be performed in adult patients in the acute period following SCI,before or after surgical intervention,to improve prediction of neurologic outcome '(quality of evidence,low).Conclusions These guidelines should be implemented into clinical practice to improve outcomes and prognostication for patients with SCI.Fehlings MG Martin AR Tetreault LA Aarabi B Anderson P Arnold PM Brodke D Burns AS Chiba K Dettori JR Furlan JC Hawryluk G Holly LT Howley S Jeji T Kalsi-Ryan S Kotter M Kurpad S Kwon BK Marino RJ Massicotte E Merli G Middleton JW Nakashima H Nagoshi N Palmieri K Singh A Skelly AC Tsai EC Vaccaro A Wilson JR Yee A Harrop JS 2017中华神经外科疾病研究杂志2017,16,6:8

12Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732).Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco 2012World Journal of Gastroenterology2012,18,26:6
13National, regional, and global trends in fasting plasma glucose and diabetes prevalence since 1980: systematic analysis of health examination surveys and epidemiological studies with 370 country-years and 2·7 million participants显示文摘Goodarz Danaei Mariel M Finucane Yuan Lu Gitanjali M Singh Melanie J Cowan Christopher J Paciorek John K Lin Farshad Farzadfar Young-Ho Khang Gretchen A Stevens Mayuree Rao Mohammed K Ali Leanne M Riley Carolyn A Robinson Majid Ezzati 2011The Lancet2011,,9785:6
14Endoscopic retrograde cholangiopancreatography in cirrhosis-a systematic review and meta-analysis focused on adverse events显示文摘AIM To investigate indications and outcomes of endoscopic retrograde cholangiopancreatography(ERCP) in cirrhotics, especially adverse events. Patients with cirrhosis undergoing ERCP are believed to have increased risk. However, there is a paucity of literature describing the indications and outcomes of ERCP procedures in patients with cirrhosis, especially focusing on adverse events.METHODS We performed a systematic appraisal of major literature databases, including PubMed and EMBASE, with a manual search of literature from their inception until April 2017.RESULTS A total of 6,505 patients from 15 studies were analyzed(male ratio 59%, mean age 59 years), 11% with alcoholic and 89% with non-alcoholic cirrhosis, with 56.2% Child-Pugh class A, and 43.8% class B or C. Indications for ERCP included choledocholithiasis 60.9%, biliary strictures 26.2%, gallstone pancreatitis 21.1% and cholangitis 15.5%. Types of interventions included endoscopic sphincterotomy 52.7%, biliary stenting 16.7% and biliary dilation 4.6%. Individual adverse events included hemorrhage in 4.58%(95%CI: 2.77-6.75%, I^2 = 85.9%), post-ERCP pancreatitis(PEP) in 3.68%(95%CI: 1.83-6.00%, I^2 = 89.5%), cholangitis in 1.93%(95%CI: 0.63-3.71%, I^2 = 87.1%) and perforation in 0.00%(95%CI: 0.00-0.23%, I^2 = 37.8%). Six studies were used for comparison of ERCPrelated complications in cirrhosis vs non-cirrhosis, which showed higher overall rates of complications in cirrhosis patients with pooled OR of 1.63(95%CI: 1.27-2.09, I2 = 65%): higher rates of hemorrhage with OR of 2.05(95%CI: 1.62-2.58, I^2 = 2.1%) and PEP with OR of 1.33(95%CI: 1.04-1.70, I2=65%), but similar cholangitis rates with OR of 1.23(95%CI: 0.67-2.26, I^2 = 44.3%).CONCLUSION There is an overall higher rate of adverse events related to ERCP in patients with cirrhosis, especially hemorrhage and PEP. A thorough risk/benefit assessment should be performed prior to undertaking ERCP in patients with cirrhosis.Shailender Singh Mashiana Amaninder Singh Dhaliwal Harlan Sayles Banreet Dhindsa Ji Won Yoo Qing Wu shailender singh Ali A Siddiqui Gordon Ohning Mohit Girotra Douglas G Adler 2018World Journal of Gastrointestinal Endoscopy2018,10,11:6
15Less common etiologies of exocrine pancreatic insufficiency显示文摘Exocrine pancreatic insufficiency(EPI), an important cause of maldigestion and malabsorption, results from primary pancreatic diseases or secondarily impaired exocrine pancreatic function. Besides cystic fibrosis and chronic pancreatitis, the most common etiologies of EPI, other causes of EPI include unresectable pancreatic cancer, metabolic diseases(diabetes); impaired hormonal stimulation of exocrine pancreatic secretion by cholecystokinin(CCK); celiac or inflammatory bowel disease(IBD) due to loss of intestinal brush border proteins; and gastrointestinal surgery(asynchrony between motor and secretory functions, impaired enteropancreatic feedback, and inadequate mixing of pancreatic secretions with food). This paper reviews such conditions that have less straightforward associations with EPI and examines the role of pancreatic enzyme replacement therapy(PERT). Relevant literature was identified by database searches. Most patients with inoperable pancreatic cancer develop EPI(66%-92%). EPI occurs in patients with type 1(26%-57%) or type 2 diabetes(20%-36%) and is typically mild to moderate; by definition, all patients with type 3 c(pancreatogenic) diabetes have EPI. EPI occurs in untreated celiac disease(4%-80%), but typically resolves on a gluten-free diet. EPI manifests in patients with IBD(14%-74%) and up to 100% of gastrointestinal surgery patients(47%-100%; dependent on surgical site). With the paucity of published studies on PERT use for these conditions, recommendations for or against PERT use remain ambiguous. The authors conclude that there is an urgent need to conduct robust clinical studies to understand the validity and nature of associations between EPI and medical conditions beyond those with proven mechanisms, and examine the potential role for PERT.Vikesh K Singh Mark E Haupt David E Geller Jerry A Hall Pedro M Quintana Diez 2017World Journal of Gastroenterology2017,23,39:5
16Role of endoscopic ultrasound in liver disease: Where do we stand in 2017?显示文摘Endoscopic ultrasound(EUS) was first introduced into medical practice in 1980 s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, is now having increasing therapeutic role as well. We provide a review of the application of EUS in the diagnostic and therapeutic aspects of liver disease. We also look at the evolving future research on the role of EUS in liver diseases.Hamzeh A Saraireh Mohammad Bilal Shailendra Singh 2017World Journal of Hepatology2017,9,24:4
17创伤性寰枢椎滑脱伴移位型齿状突骨折:采用“关节重塑”技术实现后路完全复位显示文摘寰枢椎脱位(atlantocaxial dislocation,AAD)是在先天性和创伤性情况下,寰枢关节常见的一种不正常关系,寰枢椎滑脱(atlantoaxial spondyloptosis,AAS)是指寰椎侧块小关节面完全移位,两个关节面之间无接触,是寰枢椎不稳定的一种罕见表现,属于最严重的寰枢椎脱位之一。由于寰枢关节面交锁,传统的后路手术方式或单纯凭借颅骨牵引均无法使寰枢椎完全复位。“关节操作”技术最初由Goel等提出,通过术中C1~C2撑开及进行寰枢关节操作实现颅颈交界区的重新对位。但单独使用该技术并不能达到关节复位,因此需要联合关节重塑技术(通过在C1关节面前下方边缘及C2关节面钻孔以辅助骨刀插入,获得撑开及部分复位),使寰枢关节复位到正常的解剖位置。作者对1例创伤性AAS伴移位型齿状突骨折患儿采取单纯后路手术,通过“关节操作”和“关节重塑”技术实现完全复位,效果良好。kumar a varshney g singh pk 葛苏 马向阳 2018中国骨科临床与基础研究杂志2018,10,1:3
18A selective approach to the surgical management of periampullary cancer patients and its outcome显示文摘BACKGROUND: Pancreaticoduodenectomy is a high risk, complex, technically challenging operation associated with significant perioperative morbidity and mortality. This study on the surgical management of periampullary cancer patients is based on our experience in a period of nearly 13 years.METHODS: The study was conducted on two groups of patients: group A included 42 patients who were treated between January 2000 and September 2005 and group B included 134 patients who were treated between October 2005 to October 2012. Preoperative, intraoperative and postoperative details of all these patients were collected, tabulated and analyzed to assess the impact of the selective approach introduced in the department with effect from October 2005.RESULTS: Intraoperative details revealed highly significant differences in the management of the two groups of patients in respect of operative time (250.4 vs 126.6 minutes; P<0.001), operative blood loss (1070.2 vs 414.9 m L; P<0.001) and intraoperative blood transfusion (1.4 vs 0.2 units; P<0.001). Variations between the two groups in the frequency of complications were found to be statistically insignificant. However, the difference between the two groups in the overall morbidity of patients (47.6% vs 26.1%; P=0.009) and the length of their hospital stay (11.8 vs 7.8 days; P<0.001) were significant.CONCLUSION: A selective approach applied to the surgical management of periampullary cancer patients is a step in the right direction.Omar J Shah Irfan Robbani Parveen Shah Sadaf A Bangri Irfan J Khan Mohammad Y Bhat Manmohan Singh 2014Hepatobiliary & Pancreatic Diseases International2014,13,6:3
