Concepts for increasing gentamicin release from handmade bone cement beads
BACKGROUND AND PURPOSE Commercial gentamicin-loaded bone cement beads (Septopal) constitute an effective delivery system for local antibiotic therapy. These beads are not available in all parts of the world, and are too expensive for frequent use in others. Thus, orthopedic surgeons worldwide make antibiotic-loaded beads themselves. However, these beads are usually not as effective as the comme...
متن کاملRetinal light exposure from ophthalmoscopes, slit lamps, and overhead surgical lamps. An analysis of potential hazards.
The projected beam radiance of several common ophthalmologic instruments was measured, and potential hazard to the patient from light exposure was analyzed with reference to safety standards for coherent light. The indirect ophthalmoscopes tested appear to be "safe" under moderate voltage settings, provided exposure is reasonably brief. Slit-lamp biomicroscopy of the fundus, however, merits cau...
متن کاملShader Lamps
We describe a new paradigm for three-dimensional computer graphics, using projectors to graphically animate physical objects in the real world. The idea is to replace a physical object with its inherent color, texture, and material properties with a neutral object and projected imagery, reproducing the original (or alternative) appearance directly on the object. Because the approach is to effec...
متن کاملFeatures and Operation of Hollow Cathode Lamps and Deuterium Lamps
This paper discusses the parameters which influence the operation of hollow cathode and deuterium lamps. Examples are given of how parameters can be selected in order to improve the quality of analytical results. Aspects of deuterium lamp operation for background correction are also covered.
متن کاملAutonomous Surgical Lamps
We present a novel method for the autonomous positioning of surgical lamps in open surgeries. The basic idea is to use an inexpensive depth camera to track all objects and the surgical staff and also generate a dynamic online model of the operation situs. Based on this information, our algorithms continuously compute the optimal positions for all surgical lamps. These positions can then be comm...
