| 1 | Radiofrequency ablation for treatment of hypersplenism: A feasible therapeutic option显示文摘We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation(RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism. | Guilherme Lopes P Martins Joao Paulo G Bernardes Marcello S Rovella Raphael G Andrade Publio Cesar C Viana Paulo Herman Giovanni Guido Cerri Marcos Roberto Menezes | 2015 | World Journal of Gastroenterology2015，21，20： | 17 |
| 2 | Immunoexpression of cyclooxygenase-2 in primary gastric carcinomas and lymph node metastases显示文摘AIM: To evaluate immunoexpression of cyclooxygenase-2 (COX-2) in primary gastric carcinomas and respective lymph node metastases. METHODS: Immunohistochemistry to analyze COX-2 expression was performed on tissue microarray slices obtained from 36 specimens of gastrectomy and satellite lymph nodes from patients with gastric carcinoma. RESULTS: Immunostaining was seen in most cases, and COX-2 expression was higher in lymph node me-tastases than in corresponding primary gastric tumors of intestinal, diffuse and mixed carcinomas, with a statistically signif icant difference in the diffuse histotype (P = 0.0108). CONCLUSION: COX-2 immunoexpression occurs frequently in primary gastric carcinomas, but higher expression of this enzyme is observed in lymph node metastases of the diffuse histotype. | Paulo RC Almeida Francisco VA Ferreira Cássio C Santos Francisco D Rocha-Filho Raul RP Feitosa Esther AA Falco Belise K Cavada Roberto CP Lima-Júnior Ronaldo A Ribeiro | 2012 | World Journal of Gastroenterology2012，18，8： | 14 |
| 3 | Neo-adjuvant chemo(radio)therapy in gastric cancer: Current status and future perspectives显示文摘In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence. Remaining concerns pertain to the choice of the optimal therapy regimen, strict patient selection by accurate pre-operative staging, standardization of surgical procedures, and valid criteria for response evaluation. New well-designed trials will be necessary to find the best therapeutic approach in pre-operative settings and the best way to combine old-generation chemotherapeutic drugs with new-generation molecules. | Alberto Biondi Maria C Lirosi Domenico D'Ugo Valeria Fico Riccardo Ricci Francesco Santullo Antonia Rizzuto Ferdinando CM Cananzi Roberto Persiani | 2015 | World Journal of Gastrointestinal Oncology2015，7，12： | 13 |
| 4 | Evaluation of VEGF gene polymorphisms and proliferative diabetic retinopathy in Mexican population显示文摘● AIM: To assess if the included vascular endothelial growth factor(VEGF) polymorphisms rs3025035, rs3025021 and rs2010963 are associated to proliferative retinopathy in a Mexican population with type 2 diabetes mellitus(T2DM).● METHODS: A case-control study was conducted in adult individuals with T2 DM associated to proliferative retinopathy or non-proliferative retinopathy from Oct. 2014 to Jun. 2015 from the Retina Department of the Asociation to Prevent Blindness in Mexico. The selected patients were adults with a diagnosis of T2 DM ≥5y. All subjects had a comprehensive ocular examination and the classification of the retinopathy severity was made considering the Early Treatment Diabetic Retinopathy Study(ETDRS) standardization protocols. Genomic DNA was extracted from whole fresh blood. All samples were genotyped by q PCR for selected VEGF polymorphisms. Hardy-Weinberg equilibrium was calculated by comparing Chi-square values between the expected and the observed values for genotype counts.● RESULTS: In total 142 individuals were enrolled, 71 individuals with T2 DM and associated proliferative retinopathy and 71 individuals with non-proliferative retinopathy. One-sided Fisher's exact test was performed for rs3025021[OR(95% CI)=0.44(0.08-2.2); P=0.25] and rs2010963 [OR(95% CI)=0.63(0.25-1.6); P=0.23]. The minor allelic frequencies obtained were 26% for rs3025021, 10% for rs3025035 and 61% for rs2010963. The pairwise linkage disequilibrium between the three SNP was assessed, and was as follows: rs3025021 vs rs3025035: D'=1.0, r^2=0.1043, P≤0.0001; rs3025021 vs rs2010963: D'=0.442, r^2=0.0446, P=0.149; rs3025035 vs rs2010963: D'=0.505, r^2=0.0214, P=0.142.● CONCLUSION: This is the first analysis involving VEGFA polymorphisms and proliferative diabetic retinopathy in a Mexican population. A major finding of the present study is that none of the polymorphisms studied was significantly associated with proliferative retinopathy. Based on these results, we can infer that different populations have different associations for the same polymorphisms. | Roberto Gonzalez-Salinas Maria C Garcia-Gutierrez Gerardo Garcia-Aguirre Virgilio Morales-Canton Raul Velez-Montoya Vidal R Soberon-Ventura Victoria Gonzalez Rodrigo Lechuga Pablo Garcia-Solis David G Garcia-Gutierrez Marco Vinicio Garcia-Solis Manuel Saenz de Viteri Juan C Solis-S | 2017 | International Journal of Ophthalmology(English edition)2017，10，1： | 12 |
| 5 | Phase Ⅰ of cardiac rehabilitation:A new challenge for evidence based physiotherapy显示文摘Cardiac rehabilitation protocols applied during the inhospital phase(phaseⅠ)are subjective and their results are contested when evaluated considering what should be the three basic principles of exercise prescription:specificity,overload and reversibility.In this review,we focus on the problems associated with the models of exercise prescription applied at this early stage in-hospital and adopted today,especially the lack of clinical studies demonstrating its effectiveness.Moreover,we present the concept of'periodization'as a useful tool in the search for better results. | Rafael Michel de Macedo JoséRocha Faria-Neto Costantino Ortiz Costantini Dayane Casali Andrea Pires Muller Costantino Roberto Costantini Katherine Athayde Teixeira de Carvalho Luiz César Guarita-Souza | 2011 | World Journal of Cardiology2011，3，7： | 11 |
| 6 | PPIs are not associated with a lower incidence of portal-hypertension-related bleeding in cirrhosis显示文摘AIM:To determine if proton pump inhibitor use in cirrhotic patients with endoscopic findings of portal hypertension is associated with a lower frequency of gastrointestinal bleeding.METHODS:Patients with cirrhosis and endoscopic findings related to portal hypertension,receiving or not receiving proton pump inhibitor (PPI) therapy,were included retrospectively.We assigned patients to two groups:group 1 patients underwent PPI therapy and group 2 patients did not undergo PPI therapy.RESULTS:One hundred and five patients with a median age of 58 (26-87) years were included,57 (54.3%) of which were women.Esophageal varices were found in 82 (78%) patients,portal hypertensive gastropathy in 72 (68.6%) patients,and gastric varices in 15 (14.3%) patients.PPI therapy was used in 45.5% of patients (n=48).Seventeen (16.1%) patients presented with upper gastrointestinal bleeding;in 14/17 (82.3%) patients,bleeding was secondary to esophageal varices,and in 3/17 patients bleeding was attributed to portal hypertensive gastropathy.Bleeding related to portal hypertension according to PPI therapy occurred in 18.7% (n=9) of group 1 and in 14% (n=8) of group 2 (odds ratio:0.83,95% confidence interval:0.5-1.3,P=0.51).CONCLUSION:Portal hypertension bleeding is not associated with PPI use.These findings do not support the prescription of PPIs in patients with chronic liver disease with no currently accepted indication. | Mauricio Garcia-Saenz-de-Sicilia Francisco Sanchez-Avila Norberto C Chavez-Tapia Gustavo Lopez-Arce Sandra Garcia-Osogobio Roberto Ruiz-Cordero Felix I Tellez-Avila | 2010 | World Journal of Gastroenterology2010，16，46： | 6 |
| 7 | Gastrointestinal disorders associated with migraine: A comprehensive review显示文摘Migraine is a recurrent and commonly disabling primary headache disorder that affects over 17% of women and 5%-8% of men. Migraine susceptibility is multifactorial with genetic, hormonal and environmental factors all playing an important role. The physiopathology of migraine is complex and still not fully understood. Many different neuropeptides, neurotransmitters and brain pathways have been implicated. In connection with the myriad mechanisms and pathways implicated in migraine, a variety of multisystemic comorbidities(e.g., cardiovascular, psychiatric and other neurological conditions) have been found to be closely associated with migraine. Recent reports demonstrate an increased frequency of gastrointestinal(GI) disorders in patients with migraine compared with the general population. Helicobacter pylori infection, irritable bowel syndrome, gastroparesis, hepatobiliary disorders, celiac disease and alterations in the microbiota have been linked to the occurrence of migraine. Several mechanisms involving the gut-brain axis, such as a chronic inflammatory response with inflammatory and vasoactive mediators passing to the circulatory system, intestinal microbiota modulation of the enteric immunological milieu and dysfunction of the autonomic and enteric nervous system, have been postulated to explain these associations. However, the precise mechanisms and pathways related to the gut-brain axis in migraine need to be fully elucidated. In this review, we survey the available literature linking migraine with GI disorders. We discuss the possible physiopathological mechanisms, and clinical implications as well as several future areas of interest for research. | Carlos R Cámara-Lemarroy Rene Rodriguez-Gutierrez Roberto Monreal-Robles Alejandro Marfil-Rivera | 2016 | World Journal of Gastroenterology2016，22，36： | 6 |
| 8 | Imatinib-induced fatal acute liver failure显示文摘Imatinib mesylate is a drug that has been approved for treatment of chronic myeloid leukemia (CML) in blast crisis, accelerated or chronic phase, and also for advanced gastrointestinal stromal tumors. Severe hepatic toxicity and three deaths from hepatic failure have been reported. We report the case of a 51-year-old woman who was admitted to our institution with severe acute hepatitis. She was diagnosed with CML and began treatment with imatinib mesylate at a dose of 400 mg/d. Five months after beginning treatment, she developed severe hepatitis associated with coagulopathy, and was admitted to our institution. She had been consuming acetaminophen 500-1000 mg/d after the onset of symptoms. She had a progressive increase in bilirubin level and a marked decrease of clotting factor Ⅴ. Five days after admission, grade Ⅱ encephalopathy developed and she was referred for liver transplantation. Her clinical condition progressively deteriorated, and 48 h after being referred for transplantation she suffered a cardiac arrest and died. This report adds concern about the possibility of imatinib-mesylate-induced hepatotoxicity and liver failure, particularly in the case of concomitant use with acetaminophen. Liver function tests should be carefully monitored during treatment and, with the appearance of any elevation of liver function tests, treatment should be discontinued. | Ezequiel Ridruejo Roberto Cacchione Alejandra G Villamil Sebastián Marciano Adrián C Gadano Oscar G Mandó | 2007 | World Journal of Gastroenterology2007，13，48： | 5 |
| 9 | International NeuroAIDS: prospects of HIV-1 associated neurological com-plications显示文摘Neurological complications associated with HIV-1/AIDS are being recognized with a high frequency that parallels the increased number of AIDS cases. The early infiltration by HIV-1 into the nervous system can cause primary and/or secondary neurological complications. The most common neurocognitive disorder is AIDS Dementia Complex (ADC). In developing countries of Asia the three most opportunistic infections are tuberculosis (TB), cryptococcosis, and Pneumocystis carinii pneumonia. Therefore, it is expected that secondary neurological complications due to TB and cryptococcosis will be the most common cause of morbility and mortality in HIV-1/AIDS cases in China. Research of NeuroAIDS in China is necessary to understand the impact and the biology of HIV-1 in the nervous system. Future studies would include, the molecular epidemiology and the description of opportunistic infections associated to HIV-1; the neuropathological description of primary and secondary HIV-1 complications in different groups; the HIV-1 neurot- ropism and immune response studies for China’s unique HIV-1 strains and recombinant forms derived from the nervous system, including experimental models such as the use of transgenic rats; and the study of potential resistant virus, primarily when the anti-retroviral therapy (ART) has not full access in the brain. | J Roberto TRUJILLO Gilberto JARAMILLO-RANGEL Marta ORTEGA-MARTINEZ Augusto C PENALVA de OLIVEIRA Jose E VIDAL Joseph BRYANT Robert C GALLO | 2005 | Cell Research2005，15，11： | 4 |
| 10 | Celiac disease serology in patients with different pretest probabilities: Is biopsy avoidable?显示文摘AIM: To establish the diagnostic performance of sev-eral serological tests, individually and in combination, for diagnosing celiac disease (CD) in patients with different pretest probabilities, and to explore potential se- rological algorithms to reduce the necessity for biopsy. METHODS: We prospectively performed duodenal biopsy and serology in 679 adults who had either high risk (n = 161) or low risk (n = 518) for CD. Blood samples were tested using six assays (enzyme-linked immunosorbent assay) that detected antibodies to tissue transglutaminase (tTG) and deamidated gliadin peptide (DGP). RESULTS: CD prevalence was 39.1% in the high-risk population and 3.3% in the low-risk group. In high-risk patients, all individual assays had a high diagnostic efficacy [area under receiving operator characteristic curves (AU ROC): 0.968 to 0.999]. In contrast, assays had a lower diagnostic efficacy (AU ROC: 0.835 to 0.972) in the low-risk group. Using assay combinations, it would be possible to reach or rule out diagnosis of CD without biopsy in 92% of cases in both pretest populations. We observed that the new DGP/tTG Screen assay resulted in a surplus compared to more conventional assays in any clinical situation. CONCLUSION: The DGP/tTG Screen assay could be considered as the best initial test for CD. Combinations of two tests, including a DGP/tTG Screen, might be able to diagnose CD accurately in different clinical scenarios making biopsy avoidable in a high proportion of subjects. | Emilia Sugai María L Moreno Hui J Hwang Ana Cabanne Adriana Crivelli Fabio Nach-man Horacio Vázquez Sonia Niveloni Julio Argonz Roberto Mazure Graciela La Motta María E Caniggia Edgardo Smecuol Néstor Chopita Juan C Gómez Eduardo Maurińo Julio C Bai | 2010 | World Journal of Gastroenterology2010，16，25： | 4 |
| 11 | Listeria monocytogenes following orthotopic liver transplantation:Central nervous system involvement and review of the literature显示文摘Listeria monocytogene is a well-recognized cause of bacteremia in immunocompromised individuals,including solid organ transplant recipients,but has been rarely reported following orthotopic liver transplantation. We describe a case of listeria meningitis that occurred within a week after liver transplantation. The patient developed a severe headache that mimicked tacrolimus encephalopathy,and was subsequently diagnosed with listeria meningitis by cerebrospinal fluid culture. The infection was successfully treated with three-week course of intravenous ampicillin. Recurrent hepatitis C followed and was successfully treated with interferon alfa and ribavirin. Fourteen cases of listeriosis after orthotopic liver transplantation have been reported in the English literature. Most reported cases were successfully treated with intravenous ampicillin. There were four cases of listeria meningitis,and the mortality of them was 50%. Early detection and treatment of listeria meningitis are the key to obtaining a better prognosis. | Shugo Mizuno Ivan R Zendejas Alan I Reed Robin D Kim Richard J Howard Alan W Hemming Denise C Schain Consuelo Soldevila-Pico Roberto J Firpi Shiro Fujita | 2007 | World Journal of Gastroenterology2007，13，32： | 2 |
