Minimally ablative resurfacing with the confluent 2,790 nm erbium:YSGG laser: a pilot study on safety and efficacy.

Background: The 2,790 nm Er:YSGG wavelength has a lower water absorption coefficient than the 2,940 nm Er:YAG, but a higher coefficient than the 10,600 nm CO(2) laser. This allows ablative resurfacing with mild thermal coagulation, which may increase clinical efficacy while reducing patient downtime.

Objectives: To evaluate the efficacy and safety of the confluent 2,790 nm Erbium:YSGG (Pearl™, Cutera) laser for facial rejuvenation.

Histologic analysis of a 2,940 nm fractional device.

Background And Objectives: An evaluation of the histological effects of a 2,940 nm fractional erbium:YAG (Er:YAG) laser device with adjustable depth and coagulation settings in a human abdominoplasty model. The goal of this study was to use light and confocal microscopy to determine the dimensions of the microthermal zones (MTZs) created by this device in the epidermal and dermal layers.

Study Design/materials And Methods: Three subjects were consented and treated after being randomly assigned to a laser depth of either 250 µm, 500 µm, or 1,000 µm.

Clinical study to determine the safety and efficacy of a low-energy, pulsed light device for home use hair removal.

Background And Objectives: The principle of selective photo-thermolysis has been studied extensively for hair removal applications in a medical setting. A new, portable, hand-held device featuring two filtered Xenon lamps that utilizes pulsed light in low optical fluencies for hair removal has been developed for consumer use. The purpose of this clinical study was to determine the efficacy and safety of this low-energy, pulsed-intense light device intended for home use hair removal.

Semi-Automated method of analysis of horizontal histological sections of skin for objective evaluation of fractional devices.

Background And Objective: The treatment of skin with fractional devices creates columns of micro-ablation or micro-denaturation depending on the device. Since the geometric profiles of thermal damage depend on the treatment parameters or physical properties of the treated tissue, the size of these columns may vary from a few microns to a few millimeters. For objective evaluation of the damage profiles generated by fractional devices, this report describes an innovative and efficient method of processing and evaluating horizontal sections of skin using a novel software program.

Evaluation of a novel fractional resurfacing device for treatment of acne scarring.

Background And Objective: Pulsed carbon dioxide (CO(2)) laser devices are considered highly effective treatment options for skin resurfacing. However, the high risk for significant treatment complications following CO(2) resurfacing has warranted the development of new treatment modalities. The concept of fractional photothermolysis was developed to address the shortcomings of ablative and non-ablative device modalities.

Allergic contact dermatitis from propolis.

Propolis is commonly used in cosmetic and medicinal preparations because of its antiseptic, antiinflammatory, and anesthetic properties. Its therapeutic qualities have been well documented. However, 1.
