Bariatric surgery has evolved as an effective and relatively safe treatment for morbid obesity. With nearly every region of the body as a potential operative site and an unprecedented number of surgical procedures available, we must give attention to thoughtful perioperative management. Bariatric surgery is a life-changing event for the morbidly obese patient, and the body contouring that follo...

Asians differ from Caucasians as photoageing tends to present with pigmentary changes as the main issue. Furthermore, with a higher epidermal melanin context, there is a greater risk of complications especially postinflammatory hyperpigmentation and such high epidermal melanin context also acts as a competing chromophobe for the underlying target. In this review article, recent advances in the ...

Many different techniques vary in their design and extent in skin excision. Despite the big number of techniques, the lower abdominal skin incision approach has become most popular.3 Indeed the increasing popularity of SAL since the 1980's has contributed a great deal to body-contouring techniques and the typical abdominoplasty package. Nonetheless some authorities maintain that SAL should not ...

The testing devices for performance testing on a CNC machine tool were developed. A small-radius contouring device was employed for checking the dynamic performance of a CNC machine tool. This device was composed of a laser diode and a quadrant sensor. For checking geometric error of a CNC machine tool, a long-radius contouring device was employed. The optic encoder contouring systems were also...

BACKGROUND Over the past decade, plastic surgery programs have continued to evolve with the addition of 1 year of training, increase in the minimum number of required aesthetic cases, and the gradual replacement of independent positions with integrated ones. To evaluate the impact of these changes on aesthetic training, a survey was sent to residents and program directors. METHODS A 37 questi...

Inter-observer variability in anatomical contouring is the biggest contributor to uncertainty in radiation treatment planning. Contouring studies are frequently performed to investigate the differences between multiple contours on common datasets. There is, however, no widely accepted method for contour comparisons. The purpose of this study is to review the literature on contouring studies in ...

Nonlinear and configuration-dependent five-axis kinematics make contouring errors difficult to estimate and control in real time. This paper proposes a generalized method for the on-line estimation and control of five-axis contouring errors. First, a generalized Jacobian function is derived based on screw theory in order to synchronize the motions of linear and rotary drives. The contouring err...
