| 1 | Xanthogranulomatous cholecystitis: What every radiologist should know显示文摘Xanthogranulomatous cholecystitis(XGC) is an uncommon variant of chronic cholecystitis characterized by xanthogranulomatous inflammation of the gallbladder. Intramural accumulation of lipid-laden macrophages and acute and chronic inflammatory cells is the hallmark of the disease. The xanthogranulomatous inflammation of the gallbladder can be very severe and can spill over to the neighbouring structures like liver, bowel and stomach resulting in dense adhesions, perforation, abscess formation, fistulous communication with adjacent bowel. Striking gallbladder wall thickening and dense local adhesions can be easily mistaken for carcinoma of the gallbladder, both intraoperatively as well as on preoperative imaging. Besides, cases of concomitant gallbladder carcinoma complicating XGC have also been reported in literature. So, we have done a review of the imaging features of XGC in order to better understand the entity as well as to increase the diagnostic yield of the disease summarizing the characteristic imaging findings and associations of XGC. Among other findings, presence of intramural hypodense nodules is considered diagnostic of this entity. However, in some cases, an imaging diagnosis of XGC is virtually impossible. Fine needle aspiration cytology might be handy in such patients. A preoperative counselling should include possibility of differential diagnosis of gallbladder cancer in not so characteristic cases. | Vaibhav P Singh S Rajesh Chhagan Bihari Saloni N Desai Sudheer S Pargewar Ankur Arora | 2016 | World Journal of Radiology2016，8，2： | 21 |
| 2 | Inflammation and fibrosis in chronic liver diseases including nonalcoholic fatty liver disease and hepatitis C显示文摘At present chronic liver disease(CLD),the third commonest cause of premature death in the United Kingdom is detected late,when interventions are ineffective,resulting in considerable morbidity and mortality.Injury to the liver,the largest solid organ in the body,leads to a cascade of inflammatory events.Chronic inflammation leads to the activation of hepatic stellate cells that undergo transdifferentiation to become myofibroblasts,the main extra-cellular matrix producing cells in the liver;over time increased extra-cellular matrix production results in the formation of liver fibrosis.Although fibrogenesis may be viewed as having evolved as a“wound healing”process that preserves tissue integrity,sustained chronic fibrosis can become pathogenic culminating in CLD,cirrhosis and its associated complications.As the reference standard for detecting liver fibrosis,liver biopsy,is invasive and has an associated morbidity,the diagnostic assessment of CLD by non-invasive testing is attractive.Accordingly,in this review the mechanisms by which liver inflammation and fibrosis develop in chronic liver diseases are explored to identify appropriate and meaningful diagnostic targets for clinical practice.Due to differing disease prevalence and treatment efficacy,disease specific diagnostic targets are required to optimally manage individual CLDs such as non-alcoholic fatty liver disease and chronic hepatitis C infection.To facilitate this,a review of the pathogenesis of both conditions is also conducted.Finally,the evidence for hepatic fibrosis regression and the mechanisms by which this occurs are discussed,including the current use of antifibrotic therapy. | Sudeep Tanwar Freya Rhodes Ankur Srivastava Paul M Trembling William M Rosenberg | 2020 | World Journal of Gastroenterology2020，26，2： | 17 |
| 3 | Vasopressors in obstetric anesthesia: A current perspective显示文摘Vasopressors are routinely used to counteract hypotension after neuraxial anesthesia in Obstetrics. The understanding of the mechanism of hypotension and the choice of vasopressor has evolved over the years to a point where phenylephrine has become the preferred vasopressor. Due to the absence of definitive evidence showing absolute clinical benefit of one over the other, especially in emergency and high-risk Cesarean sections, our choice of phenylephrine over the other vasopressors like mephentermine, metaraminol, and ephedrine is guided by indirect evidence on fetalacid-base status. This review article evaluates the present day evidence on the various vasopressors used in obstetric anesthesia today. | Deb Sanjay Nag Devi Prasad Samaddar Abhishek Chatterjee Himanshu Kumar Ankur Dembla | 2015 | World Journal of Clinical Cases2015，3，1： | 15 |
| 4 | Effect of preoperative biliary drainage on outcome of classical pancreaticoduodenectomy显示文摘AIM: To investigate the role of preoperative biliary drainage (PBD) in the outcome of classical pancreaticodu odenectomy. METHODS: A 10-year retrospective data analysis was performed on patients (n = 48) undergoing pancreaticoduodenectomy from March 1994 to March 2004 in department of surgery at SMS medical college, Jaipur, India. Demographic variables, details of preoperative stenting, operative procedure and post operative complications were noted. RESULTS: Preoperative biliary drainage was performed in 21 patients (43.5%). The incidence of septic complications was significantly higher in patients with biliary stent placement (P < 0.05, 0 vs 4). This group of patients also had a significantly higher minor biliary leak rate. Mortality and hospital stay in each group was comparable. CONCLUSION: Within this study population the use of PBD by endoscopic stenting was associated with a high incidence of infective complications. These findings do not support the routine use of biliary stenting in patients prior to pancreatico-duodenectomy. | Chandra Shekhar Bhati Chandrashekhar Kubal Pankaj Kumar Sihag Ankur Atal Gupta Raj Kamal Jenav Nicholas G Inston Jagdish M Mehta | 2007 | World Journal of Gastroenterology2007，13，8： | 12 |

| 6 | Platelets in Kawasaki disease:Is this only a numbers game or something beyond?显示文摘Kawasaki disease(KD)is a medium vessel vasculitis with predilection to cause coronary artery abnormalities.KD is now the most common cause of acquired heart disease in developed countries.Thrombocytosis is consistently found in patients with KD,usually in 2nd to 3rd week of illness.Thrombocytopenia has occasionally been reported in the acute phase of KD.An increase or decrease in platelet number in patients with KD was initially considered to be a benign phenomenon.However,recent literature on platelet biology in KD has suggested that platelets are not only increasing but are rather activated.This phenomenon has been found to increase the risk of thrombosis in these patients.Similarly a fall in platelet counts during acute stage of KD has also been found to be associated with increased severity of disease.In this review,we update on the current best understanding about pathogenic role of platelets in patients with KD. | Kanika Arora Sandesh Guleria Ankur Kumar Jindal Amit Rawat Surjit Singh | 2020 | Genes & Diseases2020，7，1： | 9 |
| 7 | Radiation exposure and reduction in the operating room: Perspectives and future directions in spine surgery显示文摘Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy. In attempts to reduce radiation-associated health risks, radiation safety has become an important topic in the medical field. All practitioners, regardless of practice setting, can practice radiation safety techniques including shielding and distance to reduce radiation exposure. Additionally, optimization of fluoroscopic settings and techniques can be used as an effective method of radiation dose reduction. New imaging modalities and spinal navigation systems have also been developed in an effort to replace conventional fluoroscopy and reduce radiation doses. These modalities include Isocentric Three-Dimensional C-Arms, O-Arms, and intraoperative magnetic resonance imaging. While this influx of new technology has advanced radiation safety within the field of spine surgery, more work is still required to overcome specific limitations involving increased costs and inadequate training. | Ankur S Narain Fady Y Hijji Kelly H Yom Krishna T Kudaravalli Brittany E Haws Kern Singh | 2017 | World Journal of Orthopedics2017，8，7： | 9 |
| 8 | Imaging and radiological interventions in extra-hepatic portal vein obstruction显示文摘Extrahepatic portal vein obstruction(EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension(PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late. Characteristic imaging findings include multiple parabiliary venous collaterals which form to bypass the obstructed portal vein with resultant changes in biliary tree termed portal biliopathy or portal cavernoma cholangiopathy. Ultrasound with Doppler, computed tomography, magnetic resonance cholangiography and magnetic resonance portovenography are non-invasive techniques which can provide a comprehensive analysis of degree and extent of EHPVO, collaterals and bile duct abnormalities. These can also be used to assess in surgical planning as well screening for shunt patency in post-operative patients. The multitude of changes and complications seen in EHPVO can be addressed by various radiological interventional procedures. The myriad of symptoms arising secondary to vascular, biliary, visceral and neurocognitive changes in EHPVO can be managed by various radiological interventions like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, balloon occluded retrograde obliteration of portosystemic shunt(PSS) and revision of PSS. | Sudheer S Pargewar Saloni N Desai S Rajesh Vaibhav P Singh Ankur Arora Amar Mukund | 2016 | World Journal of Radiology2016，8，6： | 8 |
| 9 | Compression Molded Ultra High Molecular Weight Polyethylene-Hydroxyapatite-Aluminum Oxide-Carbon Nanotube Hybrid Composites for Hard Tissue Replacement显示文摘Ultra high molecular weight polyethylene(UHMWPE) is widely used for articulating surfaces in total hip and knee replacements.In the present work,UHMWPE based polymer composites were synthesized by synergistic reinforcing of bioactive hydroxyapatite(HA),bioinert aluminum oxide(Al_2O_3),and carbon nanotubes(CNTs) using compression molding.Phase and microstructural analysis suggests retention of UHMWPE and reinforcing phases in the compression molded composites.Microstructural analysis elicited variation in densification due to the size effect of the reinforcing particles.The hybrid composites exhibited hardness, elastic modulus and toughness comparable to that of UHMWPE.The interfacial effect of reinforcement phases has evinced the effectiveness of Al_2O_3 over HA and CNT reinforcements,depicting synergistic enhancement in hardness and elastic modulus.Weak interfacial bonding of polymer matrix with HA and CNT requires utilization of coupling agents to achieve enhanced mechanical properties without deteriorating cytocompatible properties. | Ankur Gupta Garima Tripathi Debrupa Lahiri Kantesh Balani | 2013 | Journal of Materials Science & Technology2013，29，6： | 8 |
| 10 | Comparative analysis of APACHE-Ⅱ and P-POSSUM scoring systems in predicting postoperative mortality in patients undergoing emergency laparotomy显示文摘BACKGROUND Laparotomy remains one of the commonest emergency surgical procedures.Early prognostic evaluation would aid in selecting the high-risk patients for an aggressive treatment.Awareness about risks could potentially contribute to the quality of perioperative care and optimum utilization of resources.Portsmouth modification of Physiological and operative severity for the enumeration of mortality and morbidity (P-POSSUM) and the acute physiology and chronic health evaluation Ⅱ(APACHE-Ⅱ) have been the most widely used scoring systems for emergency laparotomies.It is always better to have a single scoring system to predict outcomes and audit healthcare organizations.AIM To compare the ability of APACHE-II and P-POSSUM to predict postoperative morbidity and mortality in patients undergoing emergency laparotomy.METHODS All patients undergoing emergency laparotomy at the Tata Main Hospital,Jamshedpur between December 2013 and November 2014 were included in the study.In this observational study,P-POSSUM and APACHE-Ⅱ scoring were done,and the outcome analysis evaluated with mortality being the primary outcome.RESULTS For P-POSSUM,at a cut off value of 63 to predict mortality using receiver operating characteristics curve analysis,the area under the curve was 0.989;and for APACHE-Ⅱ,at the cut off value of 24,the area under the curve was 0.965.CONCLUSION Because the ability of APACHE-Ⅱ to predict mortality was similar to P-POSSUM and APACHE-Ⅱ does not need scoring for intra-operative findings and histopathology reports,APACHE-Ⅱ can be used pre-operatively to assess the risk in patients undergoing emergency laparotomy.However,for audit purposes,either of the two scoring systems can be used. | Deb Sanjay Nag Ankur Dembla Pratap Rudra Mahanty Shashi Kant Abhishek Chatterjee Devi Prasad Samaddar Parul Chugh | 2019 | World Journal of Clinical Cases2019，7，16： | 5 |
| 11 | An updated review on activated PI3 kinase delta syndrome(APDS)显示文摘Activated Phosphoinositide 3-kinase d syndrome(APDS)is a newly recognised primary immunodeficiency disease.It has currently been a hot topic of clinical research and new data are emerging regarding its pathogenesis,clinical manifestations and treatment.Patients with APDS syndrome have significant autoimmune manifestations and lymphoproliferation.It is important to differentiate APDS from the usual polygenic CVID in view of the availability of targeted therapy like mTOR inhibitors such as Rapamycin and selective PI3Kd inhibitors.We provide a comprehensive review on this interesting disorder focusing light on its etiology,genetic research and emerging therapy. | Ankita Singh Vibhu Joshi Ankur Kumar Jindal Babu Mathew Amit Rawat | 2020 | Genes & Diseases2020，7，1： | 4 |
| 12 | Pregnancy and inflammatory bowel diseases: Current perspectives, risks and patient management显示文摘Inflammatory bowel diseases(IBD) are chronic idiopathic inflammatory conditions characterized by relapsing and remitting episodes of inflammation which can affect several different regions of the gastrointestinal tract, but also shows extra-intestinal manifestations. IBD is most frequently diagnosed during peak female reproductive years, with 25% of women with IBD conceiving after their diagnosis. While IBD therapy has improved dramatically with enhanced surveillance and more abundant and powerful treatment options, IBD disease can have important effects on pregnancy and presents several challenges for maintaining optimal outcomes for mothers with IBD and the developing fetus/neonate. Women with IBD, the medical team treating them(both gastroenterologists and obstetricians/gynecologists) must often make highly complicated choices regarding conception, pregnancy, and post-natal care(particularly breastfeeding) related to their choice of treatment options at different phases of pregnancy as well as post-partum. This current review discusses current concerns and recommendations for pregnancy duringIBD and is intended for gastroenterologists, general practitioners and IBD patients intending to become,(or already) pregnant, and their families. We have addressed patterns of IBD inheritance, effects of IBD on fertility and conception(in both men and women), the effects of IBD disease activity on maintenance of pregnancy and outcomes, risks of diagnostic procedures during pregnancy and potential risks and complications associated with different classes of IBD therapeutics. We also have evaluated the clinical experience using 'top-down' care with biologics, which is currently the standard care at our institution. Post-partum care and breastfeeding recommendations are also addressed. | Pegah Hosseini-Carroll Monica Mutyala Abhishek Seth Shaheen Nageeb Demiana Soliman Moheb Boktor Ankur Sheth Jonathon Chapman James Morris Paul Jordan Kenneth Manas Felix Becker Jonathan Steven Alexander | 2015 | World Journal of Gastrointestinal Pharmacology and Therapeutics2015，6，4： | 4 |

| 14 | Recent advances in elucidating the genetics of common variable immunodeficiency显示文摘Common variable immunodeficiency disorders(CVID),a heterogeneous group of inborn errors of immunity,is the most common symptomatic primary immunodeficiency disorder.Patients with CVID have highly variable clinical presentation.With the advent of whole genome sequencing and genome wide association studies(GWAS),there has been a remarkable improvement in understanding the genetics of CVID.This has also helped in understanding the pathogenesis of CVID and has drastically improved the management of these patients.A multiomics approach integrating the DNA sequencing along with RNA sequencing,proteomics,epigenetic and metabolomics profile is the need of the hour to unravel specific CVID associated disease pathways and novel therapeutic targets.In this review,we elaborate various techniques that have helped in understanding the genetics of CVID. | Vaishali Aggarwal Aaqib Zaffar Banday Ankur Kumar Jindal Jhumki Das Amit Rawat | 2020 | Genes & Diseases2020，7，1： | 4 |
| 15 | Indeterminate liver lesions on gadoxetic acid-enhanced magnetic resonance imaging of the liver:Case-based radiologic-pathologic review显示文摘Different histopathological manifestations of focal liver lesions show varying common and uncommon imaging findings and some pathologies may show similar appearance despite of different histopathology.It is necessary to characterise focal liver lesions accurately as not only benign and malignant lesions are managed differently,but also certain benign lesions have differing management.These lesions are increasingly being detected due to rapid growth of use of crosssectional imaging as well as improvement in image quality and new imaging techniques.Contrast enhanced magnetic resonance imaging(MRI)is considered the gold standard technique in characterising focal liver lesions.Addition of gadoxetic acid has been shown to significantly increase diagnostic accuracy in the detection and characterization of liver abnormalities.Classic imaging characteristics of common liver lesions,including their behaviour on gadoxetic acid enhanced MRI,have been described in literature over recent years.It is important to be familiar with the typical aspects of these lesions as well as know the uncommon and overlapping imaging features to reach an accurate diagnosis.In this article,we will review the well-described characteristic imaging findings of common and rare focal liver lesions and present several challenging cases encountered in the clinical setting,namely hepatocellular adenoma,focal nodular hyperplasia,hepatic angiomyolipoma,hepatocellular carcinoma,intrahepatic cholangiocarcinoma,neuroendocrine tumours as well as a pleomorphic liposarcoma of the liver. | Jurate Noreikaite Dekan Albasha Vijay Chidambaram Ankur Arora Ashok Katti | 2021 | World Journal of Hepatology2021，13，9： | 3 |

| 19 | Bombings specific triage(Bost Tool) tool and its application by healthcare professionals显示文摘BACKGROUND: Bombing is a unique incident which produces unique patterns, multiple and occult injuries. Death often is a result of combined blast, ballistic and thermal effect injuries. Various natures of injury, self referrals and arrival by private transportation may lead to 'wrong triage' in the emergency department. In India there has been an increase in incidence of bombing in the last 15 years. There is no documented triage tool from the National Disaster Management Authority of India for Bombings. We have tried to develop an ideal bombing specific triage tool which will guide the right patients to the right place at the right time and save more lives.METHODS: There are three methods of studying the triage tool: 1) real disaster; 2) mock drill; 3) table top exercise. In this study, a table top exercise method was selected. There are two groups, each consisting of an emergency physician, a nurse and a paramedic.RESULTS: By using the proportion test, we found that correct triaging was significantly different(P=0.005) in proportion between the two groups: group B(80%) with triage tool performed better in triaging the bomb blast victims than group A(50%) without the bombing specific triage tool performed.CONCLUSION: Development of bombing specific triage tool can reduce under triaging. | Jaiswal Sanjay Verma Ankur Kole Tamorish | 2015 | World Journal of Emergency Medicine2015，6，4： | 2 |
