1Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered.Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López 2014World Journal of Radiology2014,6,6:30
2Hepatitis B and inflammatory bowel disease: Role of antiviral prophylaxis显示文摘Hepatitis B virus (HBV) is a very common infection worldwide. Its reactivation in patients receiving immunosuppression has been widely described as being associated with significant morbidity and mortality unless anti-viral prophylaxis is administered. Treatment in inflammatory bowel disease (IBD) patients has changed in recent years and immunosuppression and biological therapies are now used more frequently than before. Although current studies have reported an incidence of hepatitis B in inflammatory bowel disease patients similar to that in the general population, associated liver damage remains an important concern in this setting. Liver dysfunction may manifest in several ways, from a subtle change in serum aminotransferase levels to fulminant liver failure and death. Patients undergoing double immunosuppression are at a higher risk, and reactivation usually occurs after more than one year of treatment. As preventive measures, all IBD patients should be screened for HBV markers at diagnosis and those who are positive for the hepatitis B surface antigen should receive antiviral prophylaxis before undergoing immunosuppression in order to avoid HBV reactivation. Tenofovir/entecavir are preferred to lamivudine as nucleos(t)ide analogues due to their better resistance profile. In patients with occult or resolved HBV, viral reactivation does not appear to be a relevant issue and regular DNA determination is recommended during immunosuppression therapy. Consensus guidelines on this topic have been published in recent years. The prevention and management of HBV infection in IBD patients is addressed in this review in order to address practicalPilar López-Serrano Jose Lázaro Pérez-Calle Maria Dolores Sánchez-Tembleque 2013World Journal of Gastroenterology2013,19,9:12
3Helicobacter pylori and autoimmune disease:Cause or bystander显示文摘Helicobacter pylori(H.pylori)is the main cause of chronic gastritis and a major risk factor for gastric cancer.This pathogen has also been considered a potential trigger of gastric autoimmunity,and in particular of autoimmune gastritis.However,a considerable number of reports have attempted to link H.pylori infection with the development of extra-gastrointestinal autoimmune disorders,affecting organs not immediately relevant to the stomach.This review discusses the current evidence in support or against the role of H.pylori as a potential trigger of autoimmune rheumatic and skin diseases,as well as organ specific autoimmune diseases.We discuss epidemiological,serological,immunological and experimental evidence associating this pathogen with autoimmune diseases.Although over one hundred autoimmune diseases have been investigated in relation to H.pylori,we discuss a select number of papers with a larger literature base,and include Sj grens syndrome,rheumatoid arthritis,systemic lupus erythematosus,vasculitides,autoimmune skin conditions,idiopathic thrombocytopenic purpura,autoimmune thyroid disease,multiple sclerosis,neuromyelitis optica and autoimmune liver diseases.Specific mention is given to those studies reporting an association of anti-H.pylori antibodies with the presence of autoimmune disease-specific clinical parameters,as well as those failing to find such associations.We also provide helpful hints for future research.Daniel S Smyk Andreas L Koutsoumpas Maria G Myt-ilinaiou Eirini I Rigopoulou Lazaros I Sakkas Dimitrios P Bogdanos 2014World Journal of Gastroenterology2014,20,3:12
4Timely reperfusion for ST-segment elevation myocardial infarction:Effect of direct transfer to primary angioplasty on time delays and clinical outcomes显示文摘Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI.Rodrigo Estévez-Loureiro ángela López-Sainz Armo Pérez de Prado Carlos Cuellas Ramón Calvio Santos Norberto Alonso-Orcajo Jorge Salgado Fernández Jose Manuel Vázquez-Rodríguez Maria López-Benito Felipe Fernández-Vázquez 2014World Journal of Cardiology2014,6,6:6
5Short and long term fate of human AMSC subcutaneously injected in mice显示文摘AIM:To study the ability of human adipose-derived mesenchymal stem cells(AMSCs)to survive over the short and long term,their biodistribution and their biosafety in vivo in tumor-prone environments.METHODS:We subcutaneously injected human AMSCs from different human donors into immunodeficient SCID mice over both short-(2 and 4 mo)and long-(17 mo)term in young,and aged tumor-prone mice.Presence of human cells was studied by immunohistochemistry and polymerase chain reaction analysis in all organs of injected mice.RESULTS:Subcutaneously injected AMSCs did not form teratomas at any time point.They did not migrate but remained at the site of injection regardless of animal age,and did not fuse with host cells in any organ examined.AMSCs survived in vivo for at least 17 mo after injection,and differentiated into fibroblasts of the subdermic connective tissue and into mature adipocytes of fat tissue,exclusively at the site of injection.CONCLUSION:Our results support the assertion that AMSC may be safe candidates for therapy when injected subcutaneously because of their long term inability to form teratomas.Pilar López-Iglesias Alejandro Blázquez-Martínez Jorge Fernández-Delgado Javier Regadera Manuel Nistal Maria P De Miguel 2011World Journal of Stem Cells2011,3,6:5
6Altered blood-brain barrier permeability in rats with prehepatic portal hypertension turns to normal when portal pressure is lowered显示文摘AIM: To study the blood-brain barrier integrity in prehe-patic portal hypertensive rats induced by partial portal vein ligation, at 14 and 40 d after ligation when portal pressure is spontaneously normalized. METHODS: Adult male Wistar rats were divided into four groups: GroupⅠ: Sham14d, sham operated; GroupⅡ: PH14d, portal vein stenosis; (both groups were used 14 days after surgery); GroupⅢ: Sham40d, Sham operated and GroupⅣ: PH40d Portal vein stenosis (GroupsⅡandⅣused 40 d after surgery). Plasma ammonia, plasma and cerebrospinal fluid protein and liver enzymes concentrations were determined. Trypan and Evans blue dyes, systemically injected, were investigated in hippocampus to study blood-brain barrier integrity. Portal pressure was periodically recorded. RESULTS: Forty days after stricture, portal pressure was normalized, plasma ammonia was moderately high, and both dyes were absent in central nervous system parenchyma. All other parameters were reestablished. When portal pressure was normalized and ammonia level was lowered, but not normal, the altered integrity of blood-brain barrier becomes reestablished. CONCLUSION: The impairment of blood-brain barrier and subsequent normalization could be a mechanism involved in hepatic encephalopathy reversibility, Hemo-dynamic changes and ammonia could trigger blood-brain barrier alterations and its reestablishment.Francisco Eizayaga Camila Scorticati Juan P Prestifilippo Salvador Romay Maria A Fernandez José L Castro Abraham Lemberg Juan C Perazzo 2006World Journal of Gastroenterology2006,12,9:3
