Efficacy of high-energy copper bromide laser (511 and 578 nm) with for deep infantile haemangioma

Evaluation of the efficacy of pro-yellow laser in the management of vascular skin disorders

BACKGROUND

Lasers have great importance in the management of vascular skin lesions.

AIM

To determine the efficacy of 577-nm pro-yellow laser in cure of certain vascular skin diseases.

MATERIAL AND METHODS

Seventy-four patients who are diagnosed as vascular skin diseases were involved in this study. All participants were treated with 577-nm pro-yellow laser with 4-week intervals. The photographs that were taken before and at every following visit were used to evaluate improvement.

RESULTS

A significant improvement occurred in port-wine stain, rosacea, facial telangiectasia, venous lake, scrotal angiokeratoma, and cherry angioma cases.

CONCLUSION

Vascular skin lesions can be treated with 577-nm pro-yellow laser with a minimal adverse effect and great success rate.

An evaluation of the efficacy of a single-session 577 nm pro-yellow laser treatment in patients with postacne erythema and scarring

Erythema and scarring are among the most common complications of severe inflammatory acne. In this study, we aimed to share our experience with pro-yellow laser and document the efficacy and safety of this treatment in postacne erythema and scarring. The study included 40 patients, 24 (60%) females, and 16 (40%) males with a mean age of 29.5 ± 8.16 (min. 18 years, max. 57 years). The pro-yellow laser was applied to all patients as a single session with irradiation of 22 J/cm² . Improvement in postacne erythema and scars were evaluated after the treatment. The study included 40 patients, 24 patients (60%) were females and 16 patients (40%) were males with the mean age of 29.5 ± 8.16 (ranged between 18 and 57 years old). A total of 21 patients (52.5%) had good improvement (51%-75% regression), 10 patients (25%) had excellent improvement (76%-100% regression), and a moderate improvement (26%-50%) was detected in 9 patients (22.5%). Also, there were mild improvement (1%-25%) in 20 patients (76.9%) and a moderate improvement (26%-50%) in 6 patients (23.1%). We found that pro-yellow laser is highly effective in the treatment of postacne erythema, while its effectiveness was mild to moderate in atrophic acne scars. Also, it has been observed that the pro-yellow laser system can be used safely immediately after cessation of systemic isotretinoin treatment.

The 577-nm pro-yellow diode laser as a reliable and effective tool for facial telangiectasia

BACKGROUND

Laser treatment of vascular skin conditions is very useful option yet remains to be a very challenging task.

AIMS

To evaluate the efficacy of 577-nm diode laser for treating facial telangiectasia.

PATIENTS AND METHODS

Thirty patients with facial telangiectasia were included in this prospective study. All participants received 3 sessions of a single-pass 577-nm diode laser. Sessions were delivered on a monthly basis, and digital photographic assessment was made at baseline and on follow-up 1 month after the last treatment.

RESULTS

At the final visit, there was a significant improvement (> 50%) reported in 21/30 (70%) patients while a poor response was reported in 2/30 (6.7%) patients. The skin phototype and site of the lesions significantly affected the result outcome (P < .05) while none of the patients' age, sex, or duration of facial telangiectasia significantly affected the treatment outcome (P > .05). Postinflammatory hyperpigmentation occurred in 2(6.7%) patients which resolved within 1.5 months.

CONCLUSION

Facial telangiectasia can be successfully treated with a 577-nm diode laser with minimal side effects.

Pilot Study of the Efficacy of 578 nm Copper Bromide Laser Combined with Intralesional Corticosteroid Injection for Treatment of Keloids and Hypertrophic Scars

Background

Treatments including intralesional corticosteroid injection, pressure therapy, cryotherapy, and various laser therapies have had limited success for keloids and hypertrophic scars.

Objective

This trial evaluated the efficacy of a combination of 578 nm copper bromide laser and the more traditional intralesional corticosteroid injection for the treatment of keloids and hypertrophic scars with respect to scar color.

Methods

Keloids or hypertrophic scars of 12 Korean patients were treated five times by the combined treatment at 4-week intervals. Clinical improvement was assessed by the physicians' global assessment (PGA) comparing pre- and post-treatment photographs, as well as 4 weeks after the last treatment. Erythema intensity was quantified using a mexameter.

Results

Most scars showed significant clinical improvement in PGA and decreased erythema intensity after 5 treatments. All patients showed improvements in symptoms like pruritus.

Conclusion

The combined treatment is effective for keloids and hypertrophic scars, especially when the telangiectatic portion of the scars is prominent. The adjunctive use of 578 nm copper bromide laser decreased the telangiectatic side effects of an intralesional corticosteroid injection by reducing the vascular components of scars.
