Iopamidol arteriography: discomfort and pain

A double-blind, randomized study was performed to compare discomfort and pain associated with the use of iopamidol and Hypaque (diatrizoate sodium and diatrizoate meglumine) during iliofemoral runoff arteriography in 33 patients. Iopamidol caused substantially less discomfort and pain. The evaluation was helped by audiotaping the study and comparing patients' vocal responses to injections of these materials.     

Antegrade internal ureteral stenting: a technical refinement

A pliable, easy to place, double pigtail, internal ureteral stent made of elastomeric polyurethane is described. The tapered distal pigtail end minimizes bladder irritation and the combination of a pusher and absorbable suture enables optimal placement of the proximal pigtail end in the renal pelvis. Ten stents used in eight patients remained functional without bladder irritation for a mean period of 8 months (range, 2-14 months).     

Urokinase in gastrointestinal tract bleeding

Selective urokinase infusion into the superior mesenteric artery allowed the accurate determination of the site of small bowel bleeding in a patient with recurrent lower gastrointestinal bleeding who bled despite resective surgery and who had negative findings on four angiograms. Fibrinolytic agents are useful in rare cases in which the need for successful and accurate diagnosis outweighs the risks of reactivating the bleeding.     

Holistic medicine and technology: A modern dialectic

This is an attempt to present a comprehensive overview of two major trends in American medicine which suggests significant evolutionary biopsychosocial developments in the remaining decades of the 20th century. Comments have been confined to the U.S. because it is the geographical country of residence and practice of the authors, and because the U.S. appears to be the locus of two contemporaneous and seemingly antithetical popular movements: quantum leaps in the development and use of medical technology and a groundswell of interest and enthusiasm for health enhancement or wellness which advocates a natural approach to health and emphasizes the central role of the individual in the preservation of health and the prevention of illness. The dynamics of this modern dialectic in American medicine have generated important qualitative consequences in the nature of the doctor-patient relationship and the delivery of health care. They have also, it is submitted, generated the search for a new paradigm which will permit a workable equilibrium between the disparate imperatives of both movements. The delicate process of developing that equilibrium is made more difficult by the co-existence of a host of complex factors, many of which are inextricably interwoven with one or the other of these two major trends.(ABSTRACT TRUNCATED AT 250 WORDS)     

The role of arteriography in abdominal aortic aneurysm

The results of arteriography in the management of 100 consecutive patients with abdominal aortic aneurysms are presented. Arteriographic information had substantial influence upon management decisions and performance of surgery in 75 per cent of cases. We found the preoperative knowledge of the precise vascular pathology or anatomic variants not only permitted a more rational recommendation for or against surgery but aided in the selection of the most suitable surgical procedure.
