1Atrophic gastritis: Risk factor for esophageal squamous cell carcinoma in a Latin-American population显示文摘AIM: To study the association between atrophic gastritis (AG) and esophageal squamous cell carcinoma (ESCC) in a Latin-America population. METHODS: A case-control study was performed at two reference Brazilian hospitals including patients diagnosed with advanced ESCC and dyspeptic patients who had been subjected to upper gastrointestinal endoscopy, with biopsies of the gastric antrum and body.All cases with ESCC were reviewed by a single pathologist, who applied standard criteria for the diagnosis of mucosal atrophy, intestinal metaplasia, and dysplasia, all classified as AG. The data on the patients' age, sex, smoking status, and alcohol consumption were collected from clinical records, and any missing information was completed by telephone interview. The association between AG and ESCC was assessed by means of univariate and multiple conditional logistic regressions. RESULTS: Most patients were male, and the median age was 59 years (range: 37-79 years) in both the ESCC and control groups. Univariate analysis showed that an intake of ethanol greater than 32 g/d was an independent risk factor that increased the odds of ESCC 7.57 times (P = 0.014); upon multiple analysis, alcohol intake of ethanol greater than 32 g/d exhibited a risk of 4.54 (P = 0.081), as adjusted for AG and smoking. Smoking was shown to be an independent risk factor that increased the odds of ESCC 14.55 times (P = 0.011) for individuals who smoked 0 to 51 packs/year and 21.40 times (P = 0.006) for those who smoked more than 51 packs/year. Upon multiple analyses, those who smoked up to 51 packs/year exhibited a risk of 7.85 (P = 0.058), and those who smoked more than 51 packs/ year had a risk 11.57 times higher (P = 0.04), as adjusted for AG and alcohol consumption. AG proved to be a risk factor that increased the odds of ESCC 5.33 times (95%CI: 1.55-18.30, P = 0.008) according to the results of univariate conditional logistic regression. CONCLUSION: There was an association by univariate conditional logistic regression between AG and ECSS in this sample of Latin-American population.Emiliano de Carvalho Almodova Walmar Kerche de Oliveira Lucas Faria Abraho Machado Juliana Rigotto Grejo Thiago Rabelo da Cunha Wagner Colaiacovo Erika Veruska Paiva Ortolan 2013World Journal of Gastroenterology2013,19,13:5
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
3Differences in viral kinetics between genotypes 1 and 3 of hepatitis C virus and between cirrhotic and non-cirrhotic patients during antiviral therapy显示文摘AIM: To evaluate the impact of hepatitis C virus (HCV) infection with genotype 1 or 3 and the presence or absence of liver cirrhosis (LC) in the early viral kinetics response to treatment. METHODS: Naive patients (n = 46) treated with interferon-α (IFN-α) and ribavirin and followed up with frequent early HCV-RNA determinations were analysed. Patients were infected with genotype 1 (n = 28, 7 with LC) or 3 (n = 18, 5 with LC). RESULTS: The fi rst phase decline was larger in geno- type 3 patients than in genotype 1 patients (1.72 vs 0.95 log IU/mL, P < 0.001). The second phase slope decline was also larger in genotype 3 patients than in genotype 1 patients (0.87 vs 0.15 log/wk, P < 0.001). Differences were found in both cirrhotic and non-cirrhotic patients. Genotype 1 cirrhotic patients had a slower 2nd phase slope than non-cirrhotic patients (0.06 vs 0.18 log/wk, P < 0.02). None of genotype 1 cirrhotic patients had a 1st phase decline larger than 1 log (non-cirrhotic patients: 55%, P < 0.02). A similar trend toward a slower 2nd phase slope was observed in genotype 3 cirrhotic pa- tients but the 1st phase slope decline was not different. Sustained viral response was higher in genotype 3 pa- tients than in genotype 1 patients (72% vs 14%, P < 0.001) and in genotype 1 non-cirrhotic patients than in genotype 1 cirrhotic patients (19% vs 0%). A secondphase decline slower than 0.3 log/wk was predictive of non-response in all groups. CONCLUSION: Genotype 3 has faster early viral decline than genotype 1. Cirrhosis correlates with a slower 2nd phase decline and possibly with a lower 1st phase slope decline in genotype 1 patients.José Eymard Medeiros-Filho Isabel Maria Vicente Guedes de Carvalho Mello Joo Renato Rebello Pinho Avidan U Neumann Fernanda de Mello Malta Luiz Caetano da Silva Flair José Carrilho 2006World Journal of Gastroenterology2006,12,45:3
4Systematic 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 2014World Journal of Clinical Cases2014,2,5:3
