Treatment of Pain in Keloids Using Only a Long-Pulsed 1064 nm Nd:YAG Laser.

Background And Objective: Keloids are benign lesions arising from overproduction of the extracellular matrix and abnormal collagen deposition by dermal fibroblasts. This altered wound healing typically occurs in response to dermal trauma. Keloid treatment poses a challenge due to the variable nature of treatment response, which can be affected by the size, appearance, and associated symptoms of erythema, pruritus, and pain.

Objective: To evaluate safety and efficacy of FRF in reducing face and neck rhytides and laxity.

Materials And Methods: This prospective, open-label, multicenter clinical trial enrolled 100 subjects with mild to severe facial and neck rhytides and laxity at seven centers in a per-protocol analysis.

Lidocaine/tetracaine peel in topical anesthesia prior to laser-assisted hair removal: Phase-II and Phase-III study results.

Background: Patient comfort is essential during dermatologic procedures.

Objectives: To evaluate anesthetic efficacy in laser-assisted hair removal of a self-occluding topical anesthetic (lidocaine 70 mg/g and tetracaine 70 mg/g, "LT peel"), which air-dries and can be peeled off 30 min post-application.

Methods: Studies A (Phase-II) and B (Phase-III) were randomized, double-blind, placebo-controlled and paired.

Photodamage therapy using an electro-optic Q-switched Nd:YAG laser.

Background And Objective: Q-Switched Nd:YAG lasers produce photoacoustic effects in addition to photothermal effects which may allow for greater tissue collagen production. The objective of the study is to determine the effectiveness and tolerability of an Electro-Optic (EO) Q-switched Nd:YAG laser with Single Pulse and novel Double Pulse (DP) options in the treatment of photodamaged skin.

Materials And Methods: Sixteen subjects with photoaging were enrolled in this prospective, randomized, split-faced study.

Long-term fine caliber hair removal with an electro-optic Q-switched Nd:YAG Laser.

Background: In spite of major advances in hair removal therapy, fine caliber hair remains a significant challenge for laser- and light-based devices.

Objective: Evaluate a novel Electro-Optic (EO) Q-switched Nd:YAG laser for pigmented fine caliber hair removal in the Standard Single and a double pulse (DP) mode.

Methods: Eleven patients underwent four laser treatments at monthly intervals.

Cutaneous compression for the laser treatment of epidermal pigmented lesions with the 595-nm pulsed dye laser.

Background: The 595-nm pulsed dye laser has been the standard of care for many vascular lesions and has rarely been used in the treatment of epidermal pigmented lesions.

Objective: The objective was to investigate the effectiveness and safety of a compression technique for the treatment of epidermal pigmented lesion using a modified 595-nm pulsed dye laser with no epidermal cooling.

Methods: Twelve subjects (mean age 58 years) underwent treatments using a modified 595-nm dye laser with a compression handpiece and no epidermal cooling.

Complications of laser dermatologic surgery.

Background And Objective: Innovations in lasers, light and radiofrequency devices have allowed for improved therapeutic efficacy and safety and the ability to treat patients with an ever-increasing number of medical and aesthetic indications. Safety remains a primary concern and the timely communication of complications and their management is vital to insure that treatments be as safe as possible. The purpose of this report on the Proceedings of the First International Laser Surgery Morbidity Meeting is to provide laser experts the opportunity to present and discuss complications that their patients have experienced and how they were successfully managed.

A quality rating scale for aesthetic surgical procedures.

Background: Cosmetic dermatologic procedures offer the promise of visible aesthetic enhancement with minimal risk. While in recent years the number of available procedures has proliferated, there are few objective methods for evaluating the relative quality of these procedures for particular indications or specific patients.

Objective: (A) To develop a simple, easy-to-use numerical rating scale to assess the quality of cosmetic surgical procedures on a range of parameters pertaining to clinical efficacy and patient satisfaction; (B) to statistically validate the discriminative value of this rating scale.

Comparison of a 1,064 nm laser and a 1,320 nm laser for the nonablative treatment of acne scars.

Background: There have been many reports of the use of nonablative lasers for the treatment of acne scars.

Objective: To evaluate the ability of the 1,064 nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser to treat acne scars and compare it with that of the 1,320 nm Nd:YAG laser.

Methods: Twelve patients with Fitzpatrick skin types I to III were randomly selected to have half of the face or back treated with the Lyra 1,064 nm Nd:YAG laser (Laserscope Corporation, San Jose, CA, USA) and the other half with the CoolTouch II 1,320 nm Nd:YAG laser (ICN Pharmaceuticals, Inc.

Hair removal using a combination radio-frequency and intense pulsed light source.

Background And Objective: The long-term removal of unwanted hair is achieved by many laser and intense pulse light sources. One limitation is the treatment of individuals with dark skin. The light energy with the current systems has to penetrate through the epidermis before being absorbed by the hair follicle.
