1Perfusion computed tomography in renal cell carcinoma显示文摘Various imaging modalities are available for the diagnosis, staging and response evaluation of patients with renal cell carcinoma(RCC). While contrast enhanced computed tomography(CT) is used as the standard of imaging for size, morphological evaluation and response assessment in RCC, a new functional imaging technique like perfusion CT(p CT), goes down to the molecular level and provides new perspectives in imaging of RCC. p CT depicts regional tumor perfusion and vascular permeability which are indirect parameters of tumor angiogenesis and thereby provides vital information regarding tumor microenvironment. Also response evaluation using p CT may predate the size criteria used in Response Evaluation Criteria in Solid Tumors, as changes in the perfusion occurs earlier following tissue kinase inhibitors before any actual change in size. This may potentially help in predicting prognosis, better selection of therapy and more accurate and better response evaluation in patients with RCC. This article describes the techniques and role of p CT in staging and response assessment in patients with RCCs.Chandan J Das Usha Thingujam Ananya Panda Sanjay Sharma Arun Kumar Gupta 2015World Journal of Radiology2015,7,7:8
2Imaging-based algorithmic approach to gallbladder wall thickening显示文摘Gallbladder(GB) wall thickening is a frequent finding caused by a spectrum of conditions. It is observed in many extracholecystic as well as intrinsic GB conditions. GB wall thickening can either be diffuse or focal. Diffuse wall thickening is a secondary occurrence in both extrinsic and intrinsic pathologies of GB, whereas, focal wall thickening is mostly associated with intrinsic GB pathologies. In the absence of specific clinical features, accurate etiological diagnosis can be challenging. The survival rate in GB carcinoma(GBC) can be improved if it is diagnosed at an early stage, especially when the tumor is confined to the wall. The pattern of wall thickening in GBC is often confused with benign diseases, especially chronic cholecystitis, xanthogranulomatous cholecystitis, and adenomyomatosis. Early recognition and differentiation of these conditions can improve the prognosis. In this minireview, the authors describe the patterns of abnormalities on various imaging modalities(conventional as well as advanced) for the diagnosis of GB wall thickening. This paper also illustrates an algorithmic approach for the etiological diagnosis of GB wall thickening and suggests a formatted reporting for GB wall abnormalities.Pankaj Gupta Yashi Marodia Akash Bansal Naveen Kalra Praveen Kumar-M Vishal Sharma Usha Dutta Manavjit Singh Sandhu 2020World Journal of Gastroenterology2020,26,40:3

4Value of neutrophil-lymphocyte ratio in evaluating response to percutaneous catheter drainage in patients with acute pancreatitis显示文摘BACKGROUND Early prediction of response to percutaneous catheter drainage(PCD)of necrotic collections in acute pancreatitis(AP)using simple and objective tests is critical as it may determine patient prognosis.The role of white blood cell(WBC)count and neutrophil-lymphocyte ratio(NLR)has not been assessed as a tool of early prediction of PCD success and is the focus of this study.AIM To assess the value of WBC and NLR in predicting response to PCD in AP.METHODS This retrospective study comprised consecutive patients with AP who underwent PCD between June 2018 and December 2019.Severity and fluid collections were classified according to the revised Atlanta classification and organ failure was defined according to the modified Marshall Score.WBC and NLR were monitored 24 h prior PCD(WBC-0/NLR-0)and 24 h(WBC-1/NLR-1),48 h(WBC-2/NLR-2)and 72 h(WBC-3/NLR-3)after PCD.NLR was calculated by dividing the number of neutrophils by the number of lymphocytes.The association of success of PCD(defined as survival without the need for surgery)with WBC and NLR was assessed.The trend of WBC and NLR was also assessed post PCD.RESULTS One hundred fifty-five patients[median age 40±13.6(SD),64.5%males,53.5%severe AP]were included in the final analysis.PCD was done for acute necrotic collection in 99(63.8%)patients and walled-off necrosis in 56(36.1%)patients.Median pain to PCD interval was 24±69.89 d.PCD was successful in 109 patients(group 1)and 46 patients(group 2)who failed to respond.There was no significant difference in the baseline characteristics between the two groups except the severity of AP and frequency of organ failure.Both WBC and NLR showed an overall decreasing trend.There was a significant difference between WBC-0 and WBC-1(P=0.0001).WBC-1 and NLR-1 were significantly different between the two groups(P=0.048 and 0.003,respectively).The area under the curve of WBC-1 and NLR-1 for predicting the success of PCD was 0.602 and 0.682,respectively.At a cut-off value of 9.87 for NLR-1,the sensitivity and specificity for predicting the success of PCD were calculated to be 75%and 65.4%respectively.CONCLUSION WBC and NLR can be used as simple tests for predicting response to PCD in patients with acute necrotizing pancreatitis.Pankaj Gupta Gaurav Chayan Das Akash Bansal Jayanta Samanta Harshal S Mandavdhare Vishal Sharma Shano Naseem Vikas Gupta Thakur Deen Yadav Usha Dutta Neelam Varma Manavjit Singh Sandhu Rakesh Kochhar 2022World Journal of Clinical Cases2022,10,1:1

8Indian task force for celiac disease:Current status显示文摘There are limited data on celiac disease(CD) from India.The limited knowledge about CD in India might be attributed to several factors.The fi rst meeting of the Indian Task Force for Celiac Disease was held in the Asian Institute of Gastroenterology,Hyderabad,India in December 2008.The objectives of the meeting were to focus research on prevalence of CD in the wheat-eating Northern vs the rice-eating Southern Indian population,low-budget serological assays to study the underprivileged population,to involve other medical subspecialties in CD,to suggest proper legislation regarding wheat food labeling,and to organize affordable food substitutes for patients with celiac disease.Rajesh Gupta Duvvuru Nageshwar Reddy Govind K Makharia Ajit Sood Balakrishnan S Ramakrishna Surender Kumar Yachha Babu Ram Thapa Rupa Banerjee Sekaran Anuradha Usha Dutta Amarender Singh Puri Ajay Kumar Jain Chris JJ Mulder Ajay Kumar Sesikeran Boindala 2009World Journal of Gastroenterology2009,15,48:1

11Drainage of pancreatic fluid collections in acute pancreatitis:A comprehensive overview显示文摘Moderately severe and severe acute pancreatitis is characterized by local and systemic complications.Systemic complications predominate the early phase of acute pancreatitis while local complications are important in the late phase of the disease.Necrotic fluid collections represent the most important local complication.Drainage of these collections is indicated in the setting of infection,persistent or new onset organ failure,compressive or pressure symptoms,and intraabdominal hypertension.Percutaneous,endoscopic,and minimally invasive surgical drainage represents the various methods of drainage with each having its own advantages and disadvantages.These methods are often complementary.In this minireview,we discuss the indications,timing,and techniques of drainage of pancreatic fluid collections with focus on percutaneous catheter drainage.We also discuss the novel methods and techniques to improve the outcomes of percutaneous catheter drainage.Akash Bansal Pankaj Gupta Anupam K Singh Jimil Shah Jayanta Samanta Harshal S Mandavdhare Vishal Sharma Saroj Kant Sinha Usha Dutta Manavjit Singh Sandhu Rakesh Kochhar 2022World Journal of Clinical Cases2022,10,20:0
