| 1 | Pneumatosis cystoides intestinalis显示文摘Pneumatosis cystoides intestinalis(PCI) is a rare condition that may be associated with a variety of diseases.The presenting clinical picture may be very heterogeneous and represent a challenge for the clinician.In the present paper we describe both a common and an uncommon clinical presentation of PCI and review the pertaining literature.Our cases confirm that,apart from asymptomatic cases,the clinical presentation of PCI may be widely different and suggest that a new onset of stipsis might be the presenting symptom.Diagnosis might be suggested by a simple X-ray of the digestive tract showing a change in the characteristics of the intestinal wall in two-thirds of these patients.However,one third of the patients do not have a suggestive X-ray and require a computed tomography(CT) scan/nuclear magnetic resonance that may reveal a thickened bowel wall containing gas to confirm the diagnosis and distinguish PCI from intraluminal air or submucosal fat.CT also allows the detection of additional findings that may suggest an underlying,potentially worrisome cause of PCI such as bowel wall thickening,altered contrast mucosal enhancement,dilated bowel,soft tissue stranding,ascites and the presence of portal air.Our results also point out that clinicians and endoscopists should be aware of the possible presentations of PCI in order to correctly manage the patients affected with this disease and avoid unnecessary surgeries.The increasing number of colonoscopies performed for colon cancer screening makes PCI more frequently casually encountered and/or provoked,therefore the possible endoscopic appearances of this disease should be well known by endoscopists. | Francesco Azzaroli Laura Turco Liza Ceroni Stefania Sartoni Galloni Federica Buonfiglioli Claudio Calvanese Giuseppe Mazzella | 2011 | World Journal of Gastroenterology2011，17，44： | 16 |
| 6 | Boceprevir is highly effective in treatment-experienced hepatitis C virus-positive genotype-1 menopausal women显示文摘AIM: To investigate the safety/efficacy of Boceprevirbased triple therapy in hepatitis C virus(HCV)-G1 menopausal women who were historic relapsers, partial-responders and null-responders. METHODS: In this single-assignment, unblinded study, we treated fifty-six menopausal women with HCV-G1, 46% F3-F4, and previous PEG-α/RBV failure(7% null, 41% non-responder, and 52% relapser) with 4 wk lead-in with PEG-IFNα2b/RBV followed by PEGIFNα2b/RBV+Boceprevir for 32 wk, with an additional 12 wk of PEG-IFN-α-2b/RBV if patients were HCV-RNApositive by week 8. In previous null-responders, 44 wk of triple therapy was used. The primary objective of retreatment was to verify whether a sustained virological response(SVR)(HCV RNA undetectable at 24 wk of follow-up) rate of at least 20% could be obtained. The secondary objective was the evaluation of the percent of patients with negative HCV RNA at week 4(RVR), 8(RVR BOC), 12(EVR), or at the end-of-treatment(ETR) that reached SVR. To assess the relationship between SVR and clinical and biochemical parameters, multiple logistic regression analysis was used.RESULTS: After lead-in, only two patients had RVR; HCV-RNA was unchanged in all but 62% who had ≤1 log10 decrease. After Boceprevir, HCV RNA became undetectable at week 8 in 32/56(57.1%) and at week 12 in 41/56(73.2%). Of these, 53.8% and 52.0%, respectively, achieved SVR. Overall, SVR was obtained in 25/56(44.6%). SVR was achieved in 55% previous relapsers vs. 41% non-responders(P = 0.250), in 44% F0-F2 vs 54% F3-F4(P = 0.488), and in 11/19(57.9%) of patients with cirrhosis. At univariate analysis for baseline predictors of SVR, only previous response to antiviral therapy(OR = 2.662, 95%CI: 0.957-6.881, P = 0.043), was related with SVR. When considering 'on treatment' factors, 1 log10 HCV RNA decline at week 4(3.733, 95%CI: 1.676-12.658, P = 0.034) and achievement of RVR BOC(7.347, 95%CI: 2.156-25.035, P = 0.001) were significantly related with the SVR, although RVR BOC only(6.794, 95%CI: 1.596-21.644, P = 0.010) maintained significance at multivariate logistic regression analysis. Anemia and neutropenia were managed with Erythropoietin and Filgrastim supplementation, respectively. Only six patients discontinued therapy. CONCLUSION: Boceprevir obtained high SVR response independent of previous response, RVR or baseline fibrosis or cirrhosis. RVR BOC was the only independent predictor of SVR. | Veronica Bernabucci Alessia Ciancio Salvatore Petta Aimilia Karampatou Laura Turco Silvia Strona Rosina Critelli Paola Todesca Caterina Cerami Caterina Sagnelli Mario Rizzetto Calogero Cammà Erica Villa | 2014 | World Journal of Gastroenterology2014，20，44： | 0 |
