Endoscopic retrograde cholangiopancreatography（ERCP）-related perforations represent rare but often severe conditions. While lesions with intraperitoneal perforation have an almost imperative indication to surgery, whether or not to manage retroperitoneal perforations surgically is still an area of debate. The aim of the present work was to review the available clinical evidence on the operatively and medi cally treated ERCP-related retroperitoneal perforations. From MEDLINE/Pub Med databases 137 patients with retroperito neal perforation were included from 12 studies that met the selection criteria for data investigation and analysis. Twenty four patients were treated by prompt surgery; 113 were primarily managed conservatively and about 20% of these patients required surgery subsequently. Overall, the morbid ity and mortality were 15.4% and 6.6%, respectively. Although most patients with retroperitoneal perforation may benefit from a non-operative management, a considerable number of patients fail to respond to medical treatment and require sur gery afterwards. Identifying those patients who are at highest risk of poor outcome after conservative treatment should be considered a research priority.

The use of colored pavements for bicycle facilities represents an interesting strategy for supporting the implementation of a high-quality cycling network. The distinctive coloration of dedicated lanes, tracks or shared paths provides a clearly delineated route, making the infrastructure more attractive as well as legible and intuitive, especially through intersections and junctions. The additional emphasis resulting from the coloring enhances a change in the road users' behavior, but its safety effectiveness seems to be particularly related to several site-specific contextual features. Although some of these benefits are well established and multiple applications of colored pavements are widespread around the world, most of cycling design standards and guides, which are usually written only in the language of the country that drafted them and are often difficult to find, completely lack in technical recommendations and concepts regarding the use of color for cycling ***, based on an extensive worldwide literature search from more than 80 official design guidelines, manuals and standards and 50 scientific articles, the authors have structured a guided overview of the state of the art/practice concerning the use of color for bike facilities at the international level, including the latest innovative and experimental schemes. The review is not intended to be a summary of manuals, but is conceived as a decision-makers' and designers' tool for a rational planning, construction, maintenance and management of colored cycling infrastructures, able to favor a cultural and technical interchange. After a first section in which the main locations where to use colored surfaces were highlighted(corridor or spot treatments), the commonly used colors(red, green and blue) have been identified, explaining the hierarchical and/or combined reasons(regulatory and legal limitations, visual-perceptual aspects and application/maintenance requirements) behind this choice.

Objective： Prognosis of colorectal cancer strongly depends on stage at diagnosis, which can be cured in most cases at an early stage. The results were supported by different screening programmes. Few data concerning analysis of different phases of Colorectal Cancer Program were reported in literature. The aim of this study is to analyze ＂step by step＂, from a longitudinal type, the Colorectal Cancer Program, active at our Institution, verifying compliance with standards of ***： We compared two different populations during the same period： patients referring to our Clinical Oncology Unit coming from Regional Colorectal Cancer Screening Program and the other population that was not in any Colorectal Cancer ***： Considering patients from the Regional Colorectal Cancer Screening Program（19 patients, corresponding to 24.0% of the general case study）, 3（15.8%） were deceased and 16（84.2%） were alive without evidence of the disease（NED）. Concerning patients that are not coming from Regional Colorectal Cancer Screening Program（61 patients, corresponding to 76.0% of the general case study）, 9（14.8%） were deceased, 43（70.5%） were NED, 8（13.1%） were alive with metastases and 1（1.6%） was lost during follow-up（PFU）. Conclusions： On the basis of this experience, we concluded for high-quality care for both populations. Any critical point should be carefully analyzed in order to implement quality of care.
