Proper patient positioning and port placement is of critical importance in robotic-assisted laparoscopic radical prostatectomy (RALP). Not having the patient in the correct Trendelenburg position or not being able to move the surgical instruments freely in the abdominal cavity can be frustrating, especially for naïve robotic surgeons (ie, those at the beginning of the learning curve for this pr...

This paper is Part II of a series of articles on Terahertz heterodyne imaging. In Part I introductory information and techniques were presented. In this paper the authors describe four different types of heterodyne imaging instruments that have been established at their facilities. In Part III (to appear in a future issue of this journal) selected applications of these instruments are discussed.

be invaluable. By this period, too, mass production was beginning to shape the face of instruments (are there deep historical relations between mass production and asepsis?). Edmonson takes his story up to 1900 when radical surgery for conservative ends was introduced. By now mass marketing accompanied mass production and the American domestic industry felt the heat of competition, notably from...

Background: The application of disinfectants on dental instruments is one way to prevent cross-infection. Cross infection can occur due microorganisms found in blood, saliva and plaque which contaminate the used by health workers. Thus, indirect contact transmission pathogenic occurs from that have been contaminated Ozone water 4.8% chloroxylenol...

OBJECTIVE To analyze the compliance with occupational post-exposure protocol for accidents and factors associated with compliance among dental surgeons.
