Several classes of nonablative laser and light technologies have been developed to target laxity, rhytides, and the various aspects of photoaging. The combination of the 3 main classes of nonablative rejuvenation, infrared laser, intense pulsed light, and radiofrequency energy, are assessed in the current study. Using a comprehensive grading scale developed to evaluate the multiple categories o...

Background: There is no difference in the functional outcomes 6 months after total knee arthroplasty (TKA) for kneeosteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to compare theshort-term clinical outcomes of TKA performed with and without the patella resurfacing.Methods: A total of 50 patients with osteoarthritis of the knee (OAK) were random...

BACKGROUND Acne scarring is treatable by a variety of modalities. Ablative carbon dioxide laser (ACL), while effective, is associated with undesirable side effect profiles. Newer modalities using the principles of fractional photothermolysis (FP) produce modest results than traditional carbon dioxide (CO(2)) lasers but with fewer side effects. A novel ablative CO(2) laser device use a technique...

BACKGROUND AND OBJECTIVES We introduce a novel CO(2) laser device that utilizes ablative fractional resurfacing for deep dermal tissue removal and characterize the resultant thermal effects in skin. STUDY DESIGN/MATERIALS AND METHODS A prototype 30 W, 10.6 microm CO(2) laser was focused to a 1/e(2) spot size of 120 microm and pulse duration up to 0.7 milliseconds to achieve a microarray patte...

BACKGROUND Fractional laser resurfacing treatment has been extensively investigated and is widely used. However, the mechanism underlying its effects is poorly understood because of the ethical and cosmetic problems of obtaining skin biopsies required to study the changes after laser treatment. OBJECTIVE To evaluate the usefulness of human skin explants for the investigation of fractional pho...
