There is a complete paucity of literature for left-handed surgeons. Some studies revealed that left-handed surgical residents have lesser operating skills and some surgeons have considered leaving surgery at some point in their career owing to laterality-related frustrations. Most important, whereas minimally invasive surgical techniques have had a profound impact on the treatment of diseased gallbladder, these procedures do not eliminate laterality related to the discomfort of left-handed surgeons. Usually, left-handed surgeons must teach themselves a procedure. They must make modifications and learn some technical tips to make a more comfortable, convenient, and safe intervention. The aim of this study was to describe some modifications made by a left-handed surgeon to perform 52 safe laparoscopic cholecystectomies with standard right-handed instruments in our hospital. These surgical steps could be used in a reproducible way to minimize the recurring difficulties of left-handed learners in a surgical residency program.
Conference Paper: Real-time interference ing method T1A.3 for mobile communication systems[Show abstract] [Hide abstract]
ABSTRACT: Deployment of next-generation wireless networks requires systems capable of operating in high-mobility environments. High performances are necessary for the antenna system and in particular the capability to reconfigure the radiated beam and adaptively change the shape of the radiation pattern in order to optimize the radiation coverage while minimizing the interferences. In this paper, a novel phase-only adaptive ing method is proposed, which is based on the description of the phase distribution of the array excitation by means of a weighted sum of proper basis functions. By optimizing the weights of this sum, rather than the phase of each element, the problem becomes almost independent of the size of the array, and its convergence speed makes it suitable for realtime applications. The present work shows that with this method both interference ing and signal tracking can be efficiently achieved.Radio and Wireless Conference, 2004 IEEE; 10/2004

ABSTRACT: Left-handedness was historically considered a disability and a social stigma, and teachers would make efforts to suppress it in their students. Little data are available on the impact of left-handedness on surgical training. This report reviews available data on this subject. We did systematic electronic and manual literature searches using a predetermined strategy independently by 2 investigators, 1 left- and 1 right-handed, to identify reports on surgical training and left-handedness. The review revealed 19 studies on the subject of left-handedness and surgical training. Data were heterogeneous and based mostly on surveys. Left-handedness produced anxiety in residents and their trainers. There was a lack of mentoring on laterality. Surgical instruments, both conventional and laparoscopic, are not adapted to left-handed use and require ambilaterality training from the resident. There is significant pressure to change hand laterality during training. However, left-handedness might present an advantage in operations involving situs inversus or left lower limb operations. Left-handedness is a challenge both for the trainee and the trainer in surgery. Early laterality-related mentoring in medical school and during surgical residency with provision of left-handed instruments might reduce the inconveniences of left-handed surgeons learning.Journal of Surgical Education 07/2010; 67(4):233-6.
