Effects of the lower energy and pulse stacking in carbon dioxide laser skin treatment: an objective analysis using second harmonic generation.

Purpose: To evaluate the effect of fractional carbon dioxide (CO2) laser treatment using lower power associated with pulse stacking within collagen fibers, using second harmonic generation microscopy and computerized image analysis.

Methods: Twenty male Wistar rats aging eight weeks were used. Each treatment area received a single-pass CO2 fractional laser with different parameters.

Comparative clinical evaluation of breast augmentation using silicone foam coated implants and textured implants.

Purpose: To evaluate whether silicone foam implants have a different evolution pattern compared to conventional texture implants.

Methods: Fifty-eight female patients underwent surgery. They were divided into two groups (silicone foam - Lifesil® - and microtexturized silicone - Lifesil®).

Patient Versus Surgeon Preferences Between Traditional and Neo-omphaloplasty in Post-bariatric Abdominoplasty.

Background: Abdominoplasty procedures have been proven highly valuable in promoting better quality of life for post-bariatric surgery patients. The literature reveals that the aspect of the navel is one of the most problematic issues regarding surgical results and many different surgical techniques have been proposed to obtain a satisfactory outcome. However, little is known about patients' preferences regarding these different techniques and their results.

Lower energy and pulse stacking. A safer alternative for skin tightening using fractional CO2 laser.

Purpose: To evaluate the effect of different energies and stacking in skin shrinkage.

Methods: Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions.
