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
2No evidence of HPV DNA in esophageal squamous cell carcinoma in a population of Southern Brazil显示文摘AIM:To investigate the association between human papillomavirus(HPV)and esophageal squamous cell carcinoma(ESCC)in southern Brazil.METHODS:We studied 189 esophageal samples from125 patients from three different groups:(1)102 biopsies from 51 patients with ESCC,with one sample from the tumor and another from normal esophageal mucosa distant from the tumor;(2)50 esophageal biopsies from 37 patients with a previous diagnosis of head and neck squamous cell carcinoma(HNSCC);and(3)37 biopsies from esophageal mucosa with normal appearance from 37 dyspeptic patients,not exposed to smoking or alcohol consumption.Nested-polymerase chain reaction(PCR)with the MY09/11 and GP5/6 L1primers was used to detect HPV L1 in samples fixed in formalin and stored in paraffin blocks.All PCR reactions were performed with a positive control(cervicovaginal samples),with a negative control(Human Genomic DNA)and with a blank reaction containing all reagents except DNA.We took extreme care to prevent DNA contamination in sample collection,processing,and testing.RESULTS:The histological biopsies confirmed the diagnosis of ESCC in 52 samples(51 from ESCC group and 1 from the HNSCC group)and classified as well differentiated(12/52,23.1%),moderately differentiated(27/52,51.9%)or poorly differentiated(7/52,13.5%).One hundred twenty-eight esophageal biopsies were considered normal(51 from the ESCC group,42 from the HNSCC group and 35 from dyspeptic patients).Nine had esophagitis(7 from the HNSCC and 2 from dyspeptic patients).Of a total of 189 samples,only 6 samples had insufficient material for PCR analysis:1 from mucosa distant from the tumor in a patient with ESCC,3from patients with HNSCC and 2 from patients without cancer.In 183 samples(96.8%)GAPDH,G3PDH and/orβ-globin were amplified,thus indicating the adequacy of the DNA in those samples.HPV DNA was negative in all the 183 samples tested:52 with ESCC,9 with esophagitis and 122 with normal esophageal mucosa.CONCLUSION:There was no evidence of HPV infection in different ESCC from southern Brazil.Luís Carlos Moreira Antunes Joo Carlos Prolla Antonio de Barros Lopes Marta Pires da Rocha Renato Borges Fagundes 2013World Journal of Gastroenterology2013,19,39:4
3Evaluation of biodegradable electric conductive tube-guides and mesenchymal stem cells显示文摘AIM: To study the therapeutic effect of three tubeguides with electrical conductivity associated to mesenchymal stem cells(MSCs) on neuro-muscular regeneration after neurotmesis.METHODS: Rats with 10-mm gap nerve injury were tested using polyvinyl alcohol(PVA), PVA-carbon nanotubes(CNTs) and MSCs, and PVA-polypyrrole(PPy). The regenerated nerves and tibialis anterior muscles were processed for stereological studies after 20 wk. The functional recovery was assessed serially for gait biomechanical analysis, by extensor postural thrust, sciatic functional index and static sciatic functionalindex(SSI), and by withdrawal reflex latency(WRL). In vitro studies included cytocompatibility, flow cytometry, reverse transcriptase polymerase chain reaction and karyotype analysis of the MSCs. Histopathology of lung, liver, kidneys, and regional lymph nodes ensured the biomaterials biocompatibility. RESULTS: SSI remained negative throughout and independently from treatment. Differences between treted groups in the severity of changes in WRL existed, showing a faster regeneration for PVA-CNTs-MSCs(P < 0.05). At toe-off, less acute ankle joint angles were seen for PVA-CNTs-MSCs group(P = 0.051) suggesting improved ankle muscles function during the push off phase of the gait cycle. In PVA-PPy and PVA-CNTs groups, there was a 25% and 42% increase of average fiber area and a 13% and 21% increase of the 'minimal Feret's diameter' respectively. Stereological analysis disclosed a significantly(P < 0.05) increased myelin thickness(M), ratio myelin thickness/axon diameter(M/d) and ratio axon diameter/fiber diameter(d/D; g-ratio) in PVA-CNT-MSCs group(P < 0.05). CONCLUSION: Results revealed that treatment with MSCs and PVA-CNTs tube-guides induced better nerve fiber regeneration. Functional and kinematics analysis revealed positive synergistic effects brought by MSCs and PVA-CNTs. The PVA-CNTs and PVA-PPy are promising scaffolds with electric conductive properties, bio- and cytocompatible that might prevent the secondary neurogenic muscular atrophy by improving the reestablishment of the neuro-muscular junction.Jorge Ribeiro Tiago Pereira Ana Rita Caseiro Paulo Armada-da-Silva Isabel Pires Justina Prada Irina Amorim Sandra Amado Miguel Franca Carolina Goncalves Maria Ascensao Lopes Jose Domingos Santos Dina Morais Silva Stefano Geuna Ana Lúcia Luís Ana Colette Maurício 2015World Journal of Stem Cells2015,7,6:2
