1Hepatic abscess induced by foreign body:Case report and literature review显示文摘Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed.Sofia A Santos Sara CF Alberto Elsa Cruz Eduardo Pires Tomás Figueira lia Coimbra José Estevez Mário Oliveira Luís Novais Joo R Deus 2007World Journal of Gastroenterology2007,13,9:10
2Hepatic ischemic preconditioning increases portal vein flow in experimental liver ischemia reperfusion injury显示文摘BACKGROUND: Ischemic preconditioning(IPC) has been shown to decrease liver injury and to increase hepatic microvascular perfusion after liver ischemia reperfusion. This study aimed to evaluate the effects of IPC on hemodynamics of the portal venous system. METHODS: Thirty-two rats were randomized into two groups: IPC group and control group. The rats of the IPC group underwent IPC by 10 minutes of liver ischemia followed by 10 minutes of reperfusion before liver ischemia, and the rats of the control group were subjected to 60 minutes of partial liver ischemia. Non-ischemic lobes were resected immediately after reperfusion. The animals were studied at 4 hours and 12 hours after reperfusion. Mean arterial pressure, heart rate, portal vein flow and pressure were analyzed. Blood was collected for the determination of the levels of aspartate aminotransferase, alanine aminotransferase, calcium, lactate, pH, bicarbonate, and base excess. RESULTS: IPC increased the mean portal vein flow at 4 hours and 12 hours after reperfusion. IPC recovered 78% of the meanportal vein flow at 12 hours after reperfusion. IPC decreased the levels of aspartate aminotransferase, alanine aminotransferase and lactate, and increased the levels of ionized calcium, bicarbonate and base excess at 12 hours after reperfusion. CONCLUSIONS: This study demonstrated that IPC increases portal vein flow and enhances hepatoprotective effects in liver ischemia reperfusion. The better recovery of portal vein flow after IPC may be correlated with the lower levels of transaminases and with the better metabolic profile.Estela RR Figueira Joel A Rocha-Filho Mauro Nakatani Marcelo FS Buto Eduardo R Tatebe Vitor O Andre Ivan Cecconello Luiz AC D'Albuquerque 2014Hepatobiliary & Pancreatic Diseases International2014,13,1:6
3Perioperative blood transfusion decreases long-term survival in pediatric living donor liver transplantation显示文摘BACKGROUND The impact of perioperative blood transfusion on short-and long-term outcomes in pediatric living donor liver transplantation(PLDLT)must still be ascertained,mainly among young children.Clinical and surgical postoperative complications related to perioperative blood transfusion are well described up to three months after adult liver transplantation.AIM To determine whether transfusion is associated with early and late postoperative complications and mortality in small patients undergoing PLDLT.METHODS We evaluated the effects of perioperative transfusion on postoperative complications in recipients up to 20 kg of body weight,submitted to PLDLT.A total of 240 patients were retrospectively allocated into two groups according to postoperative complications:Minor complications(n=109)and major complications(n=131).Multiple logistic regression analysis identified the volume of perioperative packed red blood cells(RBC)transfusion as the only independent risk factor for major postoperative complications.The receiver operating characteristic curve was drawn to identify the optimal volume of the perioperative RBC transfusion related to the presence of major postoperative complications,defining a cutoff point of 27.5 mL/kg.Subsequently,patients were reallocated to a low-volume transfusion group(LTr;n=103,RBC≤27.5 mL/kg)and a high-volume transfusion group(HTr;n=137,RBC>27.5 mL/kg)so that the outcome could be analyzed.RESULTS High-volume transfusion was associated with an increased number of major complications and mortality during hospitalization up to a 10-year follow-up period.During a short-term period,the HTr showed an increase in major infectious,cardiovascular,respiratory,and bleeding complications,with a decrease in rejection complications compared to the LTr.Over a long-term period,the HTr showed an increase in major infectious,cardiovascular,respiratory,and minor neoplastic complications,with a decrease in rejection complications.Additionally,Cox hazard regression found that high-volume RBC transfusion increased the mortality risk by 3.031-fold compared to low-volume transfusion.The Kaplan-Meier survival curves of the studied groups were compared using log-rank tests and the analysis showed significantly decreased graft survival,but with no impact in patient survival related to major complications.On the other hand,there was a significant decrease in both graft and patient survival,with high-volume RBC transfusion.CONCLUSION Transfusion of RBC volume higher than 27.5 mL/kg during the perioperative period is associated with a significant increase in short-and long-term postoperative morbidity and mortality after PLDLT.Karina Gordon Estela Regina Ramos Figueira Joel Avancini Rocha-Filho Luiz Antonio Mondadori Eduardo Henrique Giroud Joaquim Joao Seda-Neto Eduardo Antunes da Fonseca Renata Pereira Sustovitch Pugliese Agustin Moscoso Vintimilla Jose Otavio Costa Auler Jr Maria Jose Carvalho Carmona Luiz Augusto Carneiro D'Alburquerque 2021World Journal of Gastroenterology2021,27,12:6
4Pentoxifylline enhances the protective effects of hypertonic saline solution on liver ischemia reperfusion injury through inhibition of oxidative stress显示文摘BACKGROUND:Liver ischemia reperfusion(IR)injury triggers a systemic inflammatory response and is the main cause of organ dysfunction and adverse postoperative outcomes after liver surgery.Pentoxifylline(PTX)and hypertonic saline solution(HTS)have been identified to have beneficial effects against IR injury.This study aimed to investigate if the addition of PTX to HTS is superior to HTS alone for the prevention of liver IR injury.Vinicius Rocha-Santos Estela RR Figueira Joel A Rocha-Filho Ana MM Coelho Rafael Soraes Pinheiro Telesforo Bacchella Marcel CC Machado Luiz AC D'Albuquerque 2015Hepatobiliary & Pancreatic Diseases International2015,14,2:3
5Corticosteroids for severe influenza pneumonia: A critical appraisal显示文摘Influenza pneumonia is associated with high number of severe cases requiring hospital and intensive care unit(ICU) admissions with high mortality. Systemic steroids are proposed as a valid therapeutic option even though its effects are still controversial. Heterogeneity of published data regarding study design, population demographics, severity of illness, dosing, type and timing of corticosteroids administered constitute an important limitation for drawing robust conclusions. However, it is reasonable to admit that, as it was not found any advantage of corticosteroid therapy in so diverse conditions, such beneficial effects do not exist at all. Its administration is likely to increase overall mortality and such trend is consistent regardless of the quality as well as the sample size of studies. Moreover it was shown that corticosteroids might be associated with higher incidence of hospital-acquired pneumonia and longer duration of mechanical ventilation and ICU stay. Finally, it is reasonable to conclude that corticosteroids failed to demonstrate any beneficial effects in the treatment of patients with severe influenza infection. Thus its current use in s evere influenza pneumonia should be restricted to very selected cases and in the setting of clinical trials.Wagner Luis Nedel David Garcia Nora Jorge Ibrain Figueira Salluh Thiago Lisboa Pedro Póvoa 2016World Journal of Critical Care Medicine2016,5,1:3
6Grain-size end-members and environmentally sensitive grain-size components: A comparative study in the mud shelf depocenters off southern Brazil显示文摘The current study aims to do a comparative analysis of the results obtained with two End-Member(EM)grain-size modeling techniques(AnalySize and BasEMMA)and the Environmental Sensitive Grain-Size(ESGS)modeling for sediment samples collected in the mudbelts of the southern Brazilian shelf.The methods were compared using grain-size data from the south Brazilian shelf,and the results are discussed here.It is the first time that the concept of ESGS,in its present form,is utilized outside China.The results show that despite its relative ease of use,the ESGS is not fully comparable to the EM analyses,and only two grain-size ESGS classes were recognized as analogous to EMs.The comparison of the AnalySize and BasEMMA procedures also revealed significant differences between the techniques.A comparative analysis between the two EM techniques revealed advantages in the BasEMMA,especially in the better correlation of the end-members with the original grain size distribution.The analysis of the geographical distribution of the EM abundances allowed point sources of sandy populations to be recognized as well as the contribution of the Rio de la Plata as a source of silty sediments to be inferred.Michel Michaelovitch de Mahiques Samara Cazzoli y Goya Maria Carolina da Silva Nogueira de Matos Rodrigo Augusto Udenal de Oliveira Bianca Sung Mi Kim Paulo Alves de Lima Ferreira Rubens Cesar Lopes Figueira Marcia Caruso Bícego 2021International Journal of Sediment Research2021,36,2:2
