Vitamin K supplementation during prophylactic use of cefoperazone in urologic surgery.

Cefoperazone, an antibiotic commonly used for prophylaxis of infection, has been associated with hypoprothrombinemia and bleeding. To reduce the risk of bleeding, co-administration of vitamin K has been advised. We reassessed the need for vitamin K use in a retrospective analysis of 50 patients undergoing urologic procedures and who had received cefoperazone for three days to prevent infection. Eleven of 50 patients were given vitamin K because of liver or renal disease. Prothrombin time was not elevated in any of the 50 patients analyzed. We conclude that routine use of vitamin K with cefoperazone for perioperative prophylaxis of infection may be unwarranted in patients without identified risk for bleeding.

Noninvasive measurement of cardiac pressures by induced ventricular wall resonance: preliminary results in the dog.

Experiments in the excised dog heart and in live dogs are presented wherein a method of induced right ventricular wall resonance has been utlized to estimate the pressure in the right ventricle of the heart. Externally induced cardiac wall vibrations produced low frequency signals which, when subjected to spectrum analysis and coherent signal processing, permitted close approximation of static pressures and wave forms in the right ventricle at normal and hypertensive levels.

Diagnostic radiologic research: the disincentives to its propagation.

I have attempted to identify the general factors acting as impediments to diagnostic radiology research, which I have termed "external disincentives," and the more specific factors which adversely affect diagnostic radiology, termed "internal disincentives," and to present some existing recommendations for correcting them. Obviously, much work needs to be done. The real purpose of this article will have been served if it helps to point out the seriousness and complexity of the problems affecting the continuation and growth of research within diagnostic radiology.

CT demonstration of interlobar fissure calcification due to asbestos exposure.

This is the second report of calcification of the major fissure in asbestos-related pleural disease and the first in which CT was necessary to visualize its presence. This case illustrates that CT may have an additional important use in the radiologic evaluation of individuals who have had asbestos exposure.
