DNA-guided hepatitis B treatment:Viral load is insufficient with few exceptions

引用

World Journal of Gastroenterology 2009年第12期15卷 1530-1531页

作者： pankaj jain Consultant Gastroenterology Apollo Modi HospitalSwami vivekanan dnagarKota-324010RajasthanIndia

In DNA-guided hepatitis B treatment, viral load is insufficient, and requires other viral markers for treatment of hepatitis B patients as in patients with acute exacerbation of chronic hepatitis B, end-stage renal disease on dialysis, human immunodeficiency virus co-infected patients. There are exceptions to this rule： a residual level hepatitis B virus （HBV） DNA at 24 wk predicts beneficial outcome and reduced resistance at i year. The genotypic viral resistance to antiviral agents and occult HBV infection can be determined by HBV-DNA levels.

Spontaneous bacterial peritonitis:Few additional points

引用

World Journal of Gastroenterology 2009年第45期15卷 5754-5755页

作者： pankaj jain Department of Gastroenterology Fortis Modi Hospital

Spontaneous bacterial peritonitis （SBP） is a treatable complication of decompensated cirrhosis. Coagulopathy with evidence of hyperfibrinolysis or clinically evident disseminated intravascular coagulation precludes paracentesis. Alcoholic hepatitis with fever, leucocytosis and abdominal pain should be evaluated for SBP. Oral ofloxacin is as effective as parenteral cefotaxime in treatment of SBP except for inpatients with vomiting, encephalopathy, or renal failure. Albumin is superior to hydroxyethyl starch in treatment of SBR

Self-expanding metallic esophageal stents:A long way to go before a particular stent can be recommended

引用

World Journal of Gastroenterology 2011年第48期17卷 5327-5328页

作者： pankaj jain Department of Gastroenterology Fortis Modi Hospital Vivekan and Nagar324010 Kota Rajasthan India

We agree that the covered self-expanding metal stents (SEMSs) fare better than the uncovered stents as recurrent dysphagia due to tumor ingrowth is common with uncovered stent. Recent American College of Gastroenterology Practice Guideline on the Role of Esophageal Stents in Benign and Malignant Diseases concludes that SEMSs cannot be routinely recommended in conjunction with chemo-radiation. The comparison of ultraflex and choostent in the Italian study found no difference in the palliation of dysphagia, rate of complications and survival rate.

Occult hepatitis C virus infection is more common than hepatitis B infection in maintenance hemodialysis patients

引用

World Journal of Gastroenterology 2008年第14期14卷 2288-2289页

作者： pankaj jain Sandeep Nijhawan Department of Gastroenterology SMS Medical College Jaipur 302004 India

Patients of end stage renal disease on maintenance hemodialysis were enrolled to study the prevalence of occult and dual hepatitis B virus (HBV) and hepatitis C virus (HCV) infection and non-occult hepatitis B and C virus infection. One hundred and two patients were enrolled. Thirty patients had HCV infection, three of them were positive in anti-HCV. So, 27 (90%) of HCV-positive patients had occult HCV infection. Eleven (11%) patients had HBV infection. Five patients were positive in anti-HBc or HBV-DNA, but negative in HBsAg (occult HBV infection). Three (3%) patients had dual HBV and HCV infection. None of the patients showed changes in viral markers during the follow-up of 8 mo on average (1-12 mo).

Portal vein thrombosis: Etiology and clinical outcome of cirrhosis and malignancy-related non-cirrhotic, non-tumoral extrahepatic portal venous obstruction

引用

World Journal of Gastroenterology 2007年第39期13卷 5288-5289页

作者： pankaj jain Sandeep Nijhawan Department of Gastroenterology Sms Medical CollegeJaipur India

The etiology and pathogenesis of portal vein thrombosis are unclear. Portal venous thrombosis presentation differs in cirrhotic and tumor-related versus non-cirrhotic and non-tumoral extrahepatic portal venous obstruction (EHPVO). Non-cirrhotic and non-tumoral EHPVO patients are young and present with well tolerated bleeding. Cirrhosis and tumor-related portal vein thrombosis patients are older and have a grim prognosis. Among the 118 patients with portal vein thrombosis, 15.3% had cirrhosis, 42.4% had liver malignancy (primary or metastatic), 6% had pancreatitis (acute or chronic), 5% had hypercoagulable state and 31.3% had idiopathy, 12% had hypercoagulable state in the EHPVO group.

Analysis of dispatching rules in a stochastic dynamic job shop manufacturing system with sequence-dependent setup times

引用

Frontiers of Mechanical Engineering 2014年第4期9卷 380-389页

作者： pankaj SHARMA Ajai jain Department of Mechanical Engineering National Institute of Technology Kurukshetra 136119 India

Stochastic dynamic job shop scheduling pro- blem with consideration of sequence-dependent setup times are among the most difficult classes of scheduling problems. This paper assesses the performance of nine dispatching rules in such shop from makespan, mean flow time, maximum flow time, mean tardiness, maximum tardiness, number of tardy jobs, total setups and mean setup time performance measures viewpoint. A discrete event simulation model of a stochastic dynamic job shop manufacturing system is developed for investigation purpose. Nine dispatching rules identified from literature are incorporated in the simulation model. The simulation experiments are conducted under due date tightness factor of 3, shop utilization percentage of 90 % and setup times less than processing times. Results indicate that shortest setup time （SIMSET） rule provides the best performance for mean flow time and number of tardy jobs measures. The job with similar setup and modified earliest due date （JMEDD） rule provides the best performance for make- span, maximum flow time, mean tardiness, maximum tardiness, total setups and mean setup time measures.
