ABSTRACTCities need social infrastructure, places that support social connection in neighborhoods and across communities. In the face of austerity in many places, the provision of such infrastructures are under threat. To protect such infrastructures, it is important to have robust arguments for their provision, maintenance, and protection. Through a case study of a dispute about the appropriate use and provisioning of an everyday park located in London, UK, this article examines what social infrastructure is and why it matters. The dispute has brought to the surface a number of critical questions about how to fund and provide collective, public social life. It has also raised questions about what types of social and collective life should be valued. To examine the dispute a sixfold typology is developed to explore the different registers of sociality afforded by social infrastructure: co-presence, sociability and friendship, care and kinship, kinesthetic practices, and civic engagement.

Mammography and physical examination of the breast are evaluated as screening instruments for detecting breast cancer based on local biopsy data obtained from women enrolled in a national breast cancer screening program. One hundred thirteen cancers (15.5% of women who underwent biopsy) were detected. The individual sensitivities of mammography and physical examination for detecting breast cancer are 62% and 24%, respectively. The sensitivity of the two methods combined is 75% (85 of 113). Thirty-seven cancers were in situ or minimally invasive (≤1 cm in greatest dimension). Eighty-one percent (30 of 37) of these small cancers were detected by screening, and they comprised 35% (30 of 85) of all cancers detected by mammography, physical examination, or both. Improved survival is anticipated due to this high rate of discovery of small cancers.(JAMA 242:2080-2083, 1979)

Enough cases of the fatal cutaneointestinal syndrome malignant papulosis with atrophy have now been reported so that it can be considered a clinical and pathologic entity. When, in 1942, Degos et al.1 presented their first patient, then having only skin lesions, they were unaware of the future fatal outcome, but nevertheless felt that the patient had a previously undescribed disease of the skin. Several months later the man died after a severe acute gastrointestinal condition. At operation, and later at autopsy, there was no perforation of the intestine, but many yellow lesions of the small intestine were found. These atrophic lesions of the intestine were identifiable, both microscopically and macroscopically with the atrophic skin lesions, and were assumed to have the same causation.The history of development, the character and type of the eruptive lesions are very uniform in all the cases reported. Degos' first case illustrates the course

Chronic ulcerative colitis is a disease of protean manifestations involving many anatomical systems but with the distinguishing features of colonic inflammatory mucosal ulceration, fibrosis of the bowel wall, and relative uninvolvement of the colonic serosal surfaces. Of the many complications of ulcerative colitis, there are a group of catastrophic conditions occurring within the colon, namely, perforation, massive bleeding, and carcinoma.1 To these obstruction might well be added, although it overlaps with the complications named, for the obstruction may be neoplastic, cicatricial, or it may be adynamic. This latter occurs in fulminating attacks, dangerous especially because dilation tends to accentuate colonic wall necrosis and thus leads to perforation and peritonitis. This report is directed to a review of actual colonic wall perforation or threatened colonic wall necrosis in 13 ulcerative colitis patients at the State University of Iowa Hospitals, 11 in fulminant attacks and 2 with acute focal perforations.

This is an article the presents the comments of Canadian politician Jack Layton on why he likes politics. I entered federal politics because I wanted to help restore hope, and I believe passionately that politics should matter. One of those ideas was retrofitting buildings for energy efficiency-paid for by future energy savings. With energy prices rising, workers looking for jobs and climate change taking its toll, why aren't we doing more things like this? People tell me they're not interested in politics, but I think it's because for so long politics hasn't tried to involve people. Let this be the election in which we finally have a debate about the positive choices we can make together-because we desperately need to put hope back into politics.
