A new cost-effective device for the detection of sponges and other instruments left accidentally in the surgical field is presented. This device has 100 per cent sensitivity rate in the initial tests. It is extremely simple and rapid and does not require the use of radiation or other harmful techniques.

[Morphological lesions of the choledochus studied with combined percutaneous transhepatic cholangiography and hypotonic duodenography].

Twenty two patients obstructive jaundice were investigated by combined fine needle percutaneous cholangiography and hypotonic duodenography. The association of the two techniques enables prompt localization of the site of obstruction and definition of the nature of the lesion. It proves to be of particular use in the differential diagnosis of carcinoma of the head of the pancreas, carcinoma of the distal choledochus and carcinoma of the socalled choledochoduodenal junction.

[Radiologic patterns of the metastatic tumours of the large intestine (author's transl)].

The metastatic tumours of the large intestine are not unfrequent. In the majority of cases they are due to the direct invasion from endo or retro peritoneal tumours, especially of the stomach and the pancreas. The radiologic findings of such lesions are described, and a correlation is made with the pathologic, pathogenetic and clinical aspects.

[Plain abdominal film in neoplasms of the large bowel. - A comparative study with a population of normal subjects (author's transl)].

A comparative study was performed between plain abdominal films of 110 patients with neoplasms of the large bowel and 52 normal subjects for control. In neoplasms of the right colon the failed spontaneous visualization of caecum and ascendent colon or the direct recognization of lume's deformation allow us to suspect such a lesions in about 90% of the cases. Neoplasms of the other tracts of the large bowel may be suspected only when plain abdominal film demonstrates direct evidence of an obstruction: in about 25% of the cases.

Finding a lasting cure for U.S. health care.

In "Making Competition in Health Care Work" (July-August 1994), Elizabeth Olmsted Teisberg, Michael E. Porter, and Gregory B. Brown ask a question that has been absent from the national debate on health care reform: How can the United States achieve sustained cost reductions while at the same time maintaining quality of care? The authors argue that innovation driven by rigorous competition is the key to successful reform. A lasting cure for health care in the United States should include four basic elements: corrected incentives to spur productive competition, universal insurance to secure economic efficiency, relevant information to ensure meaningful choice, and innovation to guarantee dynamic improvement. In this issue's Perspectives section, eleven experts examine the current state of the health care system and offer their views on the shape that reform should take. Some excerpts: "On the road to innovation, let us not forget to develop the tools that allow physicians, payers, and patients to make better decisions." I. Steven Udvarhelyi; "Health care is not a product or service that can be standardized, packaged, marketed, or adequately judged by consumers according to quality and price." Arnold S. Relman; "Just as antitrust laws are the wise restraints that make competition free in other sectors of the economy, so the right kind of managed competition can work well in health care." Edward M. Kennedy "Biomedical research should be considered primarily an investment in the national economic well-being with additional humanitarian benefits." Elizabeth Marincola.
