| 1 | Evaluation of quantitative contrast harmonic imaging to assess malignancy of liver tumors:A prospective controlled two-center study显示文摘AIM: To establish the extent to which contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics facilitates the detection of hepatic tumors. METHODS: One hundred patients with histologically confirmed malignant or benign hepatic tumor (maximum size 5 cm) were analyzed. Contrast-enhanced ultrasound (bolus injection 2.5 mL SonoVue) was carried out with intermittent breath-holding technique using a multifrequency transducer (2.5-4 MHz). Native vascularization was analyzed with power Doppler. The contrast-enhanced dynamic ultrasound investigation was carried out with contrast harmonic imaging in true detection mode during the arterial,portal venous and late phases. Mechanical index was set at 0.15. Perfusion analysis was performed by post-processing of the raw data time intensity curve (TIC) analysis. The cut-off of the gray value differences between tumor and normal liver tissue was established using Receiver Operating Characteristic (ROC) analysis 64-line multi-slice computed tomography served as reference method in all cases. Magnetic resonance tomography was used additionally in 19 cases. RESULTS: One hundred patients with 59 malignant (43 colon,5 breast,2 endocrine metastases,7 hepatocellular carcinomas and 2 kidney cancers) and 41 benign (15 hemangiomas,7 focal nodular hyperplasias,5 complicated cysts,2 abscesses and 12 circumscribed fatty changes) tumors were included. The late venous phase proved to be the most sensitive for classification of the tumor type. Fifty-eight of the 59 malignant tumors were classified as true positive,and one as false negative. This resulted in a sensitivity of 98.3%. Of the 41 benign tumors,37 were classified as true negative and 4 as false negative,which corresponds to a specificity of 90.2%. Altogether,95.0% of the diagnoses were classified as correct on the basis of the histological classification. No investigator-dependency (P = 0.23) was noted. CONCLUSION: The results show the possibility of accurate prediction of malignancy of hepatic tumors with a positive prognostic value of 93.5% using advanced contrast-enhanced ultrasound. Contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics is a valuable tool to discriminate hepatic tumors. | EM Jung DA Clevert AG Schreyer S Schmitt J Rennert R Kubale S Feuerbach F Jung | 2007 | World Journal of Gastroenterology2007,13,47: | 15 |
| 2 | Cytokines,cytokine gene polymorphisms and Helicobacter pylori infection:Friend or foe?显示文摘Helicobacter pylori(H.pylori)is a flagellated,spiralshaped,microaerophilic Gram-negative bacillus that colonises the gastric mucosa of more than 50%of the human population.Infection is a risk factor for gastritis,ulcer disease and stomach cancer.Immunity against H.pylori is mainly related to Th1/Th17 skewing,and the activation of regulatory T cells is the main strategy used to limit inflammatory responses,which can result in the pathogen persistence and can lead to chronic gastrointestinal diseases,including cancer.Furthermore,host genetic factors that affect cytokines may determine differences in the susceptibility to many diseases.In this review,we present the cytokine profiles and the main cytokine gene polymorphisms associated with resistance/susceptibility to H.pylori and discuss how such polymorphisms may influence infection/disease outcomes. | Camila A Figueiredo Cintia Rodrigues Marques Ryan dos Santos Costa Hugo Bernardino F da Silva Neuza M Alcantara-Neves | 2014 | World Journal of Gastroenterology2014,20,18: | 11 |
| 3 | Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy显示文摘Hepatic encephalopathy(HE)is a cognitive disturbance characterized by neuropsychiatric alterations.It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts.The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.Therefore,the embolization of these shunts has been performed tocontrol HE manifestations,but the presence of portal vein thrombosis is considered a contraindication.In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt.Case report:a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma,even without precipitant factors.She had a wide portosystemic shunt and also portal vein thrombosis.The abdominal angiography confirmed the splenorenal shunt and showed other shunts.The larger shunt was embolized through placement of microcoils,and the patient had no recurrence of overt HE.There was a little increase of esophageal and gastric varices,but no endoscopic treatment was needed.Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients,portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization.However,in particular cases with many shunts and severe HE,we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery.In conclusion,we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis.As the patient had other shunts,she was successfully treated by embolization of the larger shunt. | Letícia de Campos Franzoni Fábio Cardoso de Carvalho Rafael Gomes de Almeida Garzon Fábio da Silva Yamashiro Laís Augusti Lívia Alves Amaral Santos Mariana de Souza Dorna Júlio Pinheiro Baima Talles Bazeia Lima Carlos Antonio Caramori Giovanni Faria Silva Fernando Gomes Romeiro | 2014 | World Journal of Gastroenterology2014,20,42: | 6 |
| 4 | Exercise manual for liver disease patients显示文摘AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation.METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index(BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease(MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure(MIP) and maximal expiratory pressure, spirometry, root mean square(RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference(P = 0.01) between the first(initial) and the third month(final) MIP in the control group and in the intervention group, but there was no difference(P = 0.45) between the groups.The RMS of the diaphragm was lower(P = 0.001) and the functional capacity was higher(P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group(P = 0.01) and the intervention group(P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group(P = 0.083) and intervention group(P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups(P = 0.21). In the intervention group, patients with ascites at the end of the time period had decreased scores on the social aspects SF-36 domain(P = 0.023) compared to those who had no ascites. CONCLUSION: The proposed exercises provide an increase in the inspiratory muscle strength and improve functional capacity, consequently bettering the quality of life of liver disease patients. | Vivian Limongi Daniele Costa Dos Santos Aurea Maria de Oliveira da Silva Ilka de Fátima Santana Ferreira Boin Raquel Silveira Bello Stucchi | 2016 | World Journal of Transplantation2016,6,2: | 3 |
| 5 | Systematic review of noninvasive treatments to arrest dentin non-cavitated caries lesions显示文摘AIM: To systematically review the literature on the efficacy of noninvasive methods of arresting the progression of non-cavitated occlusal carious lesions in dentin.METHODS: The Medline/Pub Med,LILACS,Sci ELO and Scopus databases were searched to identify relevant publications through to November 2013.Only clinical trials evaluating the ability of noninvasive methods to arrest the progression of occlusal non-cavitated carious lesions in dentin were included.Screening,data extraction and quality assessment were conducted independently and in duplicate.RESULTS: Of 167 citations identified,nine full text articles were screened and five were included in the analysis.All papers reported on occlusal fissure sealing using a self-curing glass ionomer(n = 1) or resin-based(n = 4) sealant.Only the use of resin-based sealant to obliterate occlusal fissures arrested the progression of non-cavitated occlusal carious lesions in dentin.CONCLUSION: Occlusal fissure sealing with a resin-based sealant may arrest the progression of non-cavitated occlusal dentinal caries.Further clinical trials with longer follow-up times should be performed to increase scientific evidence. | Isauremi Vieira de Assun??o Giovanna de Fátima Alves da Costa Boniek Castillo Dutra Borges | 2014 | World Journal of Clinical Cases2014,2,5: | 3 |
| 6 | Acute fatty liver of pregnancy associated with severe acute pancreatitis:A case report显示文摘Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed. | Cássio Vieira de Oliveira Alecsro Moreira Julio P Baima Leticia de C Franzoni Talles B Lima Fabio da S Yamashiro Kunie Yabuki Rabelo Coelho Ligia Y Sassaki Carlos Antonio Caramori Ferno G Romeiro Giovanni F Silva | 2014 | World Journal of Hepatology2014,6,7: | 3 |

| 8 | Relationship between head and neck cancer therapy and some genetic endpoints显示文摘Head and neck cancer(HNC) is the sixth most common human malignancy worldwide. The main forms of treat ment for HNC are surgery, radiotherapy(RT) and che motherapy(CT). However, the choice of therapy de pends on the tumor staging and approaches, which are aimed at organ preservation. Because of systemic RT and CT genotoxicity, one of the important side effects is a secondary cancer that can result from the activity of radiation and antineoplastic drugs on healthy cells Ionizing radiation can affect the DNA, causing single and double-strand breaks, DNA-protein crosslinks and oxidative damage. The severity of radiotoxicity can be directly associated with the radiation dosimetry and the dose-volume differences. Regarding CT, cisplatin is stil the standard protocol for the treatment of squamous cell carcinoma, the most common cancer located in theoral cavity. However, simultaneous treatment with cisplatin, bleomycin and 5-fluorouracil or treatment with paclitaxel and cisplatin are also used. These drugs can interact with the DNA, causing DNA crosslinks, double and single-strand breaks and changes in gene expression. Currently, the late effects of therapy have become a recurring problem, mainly due to the increased survival of HNC patients. Herein, we present an update of the systemic activity of RT and CT for HNC, with a focus on their toxicogenetic and toxicogenomic effects. | Eliana Maria Minicucci Glenda Nicioli da Silva Daisy Maria Fávero Salvadori | 2014 | World Journal of Clinical Oncology2014,5,2: | 2 |
