| 1 | Role of endoscopic retrograde cholangiopancreatography inthe management of benign biliary strictures:What's new?显示文摘Benign biliary strictures comprise a heterogeneous group of diseases. The most common strictures amenable to endoscopic treatment are post-cholecystectomy, post-liver transplantation, related to primary sclerosing cholangitis and to chronic pancreatitis. Endoscopic treatment of benign biliary strictures is widely used as first line therapy, since it is effective, safe, noninvasive and repeatable. Endoscopic techniques currently used are dilation, multiple plastic stents insertion and fully covered self-expandable metal stents. The main indication for dilation alone is primary sclerosing cholangitis related strictures. In the vast majority of the remaining cases, temporary placement of multiple plastic stents with/without dilation is considered the treatment of choice. Although this approach is effective, it requires multiple endoscopic sessions due to the short duration of stent patency. Fully covered self-expandable metal stents appear as a good alternative to plastic stents, since they have an increased radial diameter, longer stent patency, easier insertion technique and similar efficacy. Recent advances in endoscopic technique and various devices have allowed successful treatment in most cases. The development of novel endoscopic techniques and devices is still ongoing. | Rosa Ferreira Rui Loureiro Nuno Nunes António Alberto Santos Rui Maio Marília Cravo Maria AntóniaDuarte | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，4： | 6 |

| 3 | Crohn's disease environmental factors in the developing world: A case-control study in a statewide catchment area in Brazil显示文摘AIM To identify environmental risk factors associated with the development of Crohn's disease(CD) in order to reassess the hygiene hypothesis.METHODS A hospital-based, case-control study was carried out with CD patients(n = 145) and controls(n = 163)representing a socioeconomically diverse statewide catchment area in Brazil. Controls were recruited from caregivers of patients seen in different outpatient clinics at the same hospital. A multi-item survey with 94 questions regarding family history of CD, perinatal and childhood circumstances, living conditions, tobacco use and familial socioeconomic status was carried out by interviewers. RESULTS On the univariate analysis, predictive variables for CD included being male, under age of 40, a high education level, urban dweller, smaller family size, exposure to enteric pathogens and user of treated water(P < 0.005). On the multivariate analysis, variables significantly associated with CD were male gender(OR = 2.09), under age 40(OR = 3.10), white(OR = 2.32), from a small family in childhood(OR = 2.34) and adulthood(OR = 3.02), absence of viral infections in childhood(OR = 2.23), exposure to enteric pathogens(OR = 2.41), having had an appendectomy(OR = 2.47) and prior or current smoker(OR = 2.83/1.12). CONCLUSION Most variables supporting the 'hygiene hypothesis' are associated with the development of CD but are not independent predictors of the diagnosis. | Valéria Cristina Loureiro Salgado Ronir Raggio Luiz Neio Boechat Bianca C Schorr Isabella S Leao Tiago Nunes Cyrla Zaltman | 2017 | World Journal of Gastroenterology2017，23，30： | 2 |
| 4 | Normative data for TM electrocochleography measures显示文摘Objective: Establish normative data for tympanic electrocochleography(TM ECoch G) parameters in normal hearing adults without Meniere's disease's(MD) symptoms. Describe TM ECoch G variables that help to distinguish normal from MD ears.Material and methods: We enrolled 100 subjects(N =200 ears), 59 females, aged between 19 and 71 years from 09/2010 to 04/2014. Inclusion criteria: normal otomicroscopy, hearing thresholds≤25 dB nHL from 250 to 4000 Hz, normal tympanogram, no symptoms of MD according to the AAO-HNS 1995 criteria and Gibson's score <7. We excluded subjects with dizziness, aural fullness or other symptoms of endolymphatic hydrops. The following parameters were analyzed: SP/AP amplitude ratio, SP/AP area ratio and the difference between AP latency with rarefaction and condensation stimuli.Results: There was no significant difference between right and left ears(Intraclass correlation coefficient < 0.6). SP/AP amplitude ratio varied between 0.084 and 0.356 and SP/AP area ratio between 0.837 and 1.671(percentiles 5 and 95). The AP latency difference to rarefaction and condensation clicks was between 0.0 and 0.333 ms.Conclusion: Normative data for TM ECoch G parameters were established in 100 normal hearing subjects without MD. These data can be used to distinguish normal from pathological findings and in follow-up of MD patients. | Signe Schuster Grasel Roberto Miquelino de Oliveira Beck Ricardo Silva Chiabai Loureiro Amanda Costa Rossi Edigar Rezende de Almeida John Ferraro | 2017 | Journal of Otology2017，12，2： | 2 |
