OBJECTIVES To measure and compare postoperative erythema after laser cutaneous resurfacing using 2 carbon dioxide laser systems and varying postoperative treatment methods. DESIGN Carbon dioxide laser systems are used as cutaneous resurfacing tools. The continuous-wave lasers have been associated with postoperative erythema, but the short-pulsed lasers reportedly result in less postoperative ...

Tim LASER (Light Amplification by Stimulated Emission of Radiation), was first introduced into medicine about a decade ago, and within this relatively short time, has added a new dimension to medical science. A variety of substances (solids and gases) can stimulate laser emissions. Lasers vary in wavelength and physical properties. These variations make them useful for a variety of clinical and...

OBJECTIVE To assess the advantages of powered instrumentation vs the carbon dioxide laser in treating patients with juvenile-onset recurrent respiratory papillomatosis. DESIGN A retrospective study. SETTING Tertiary care children's hospital. PATIENTS Patients operated on for juvenile-onset recurrent respiratory papillomatosis between January 1, 1999, and December 31, 2000. Papillomas were...

The present work was targeted to design a surface against cell seeding and adhering of bacteria, Bacillus subtilis. A multi-walled carbon nanotube/titanium dioxide nano-power was produced via simple mixing of carbon nanotube and titanium dioxide nanoparticles during the sol-gel process followed by heat treatment. Successfully, quercetin was immobilized on the nanocomposite via physical adsorpti...

BACKGROUND While skin resurfacing using pulsed carbon dioxide lasers appears to have a skin-tightening effect clinically, the debate continues over its actual effects on dermal collagen. OBJECTIVES To provide quantitative measures of skin elasticity changes associated with pulsed carbon dioxide laser skin resurfacing and to introduce to the facial plastic surgery community the Cutometer SEM 5...

Reports have been published describing successful in vivo recanalization of atherosclerotic plaque-occluded peripheral and coronary arteries using energy from argon and carbon dioxide laser sources [1-3]. In the case of the argon laser, optical fibers acting as waveguides incorporated in catheters were used. In the case of the carbon dioxide laser, direct lineof-sight application through a need...

BACKGROUND Injection of calcium hydroxylapatite filler may result in nodule formation owing to superficial placement of the filler. Calcium hydroxylapatite nodules are difficult to reverse. Previously reported therapeutic options are limited and include intralesional triamcinolone, massage, needling, and excision, each with inconsistent results or potential for scarring. OBSERVATION We have o...
