Traitement par laser CO2 Fractionné :
Etude sur les traitement par laser CO2 Fractionné et amélioration de la profondeur des rides :
Summary : The clinical application of the fractional CO2 laser shows a clear reduction of wrinkles. In particular, the elastosis and hyperpigmentation was visibly improved after several sessions. The best results are visible several weeks after the therapy, due to the time necessary for the remodeling processes of the collagen. Downtime varies between 3 to 10 days, depending on the selected laser parameters. Side effects such as scars, or hyper- and hypopigmentation rarely occur. In any case, herpes prophylaxis is recommended. The treatment method described above is currently being evaluated at the Department of Dermatology, University of Regensburg, Germany in a prospective controlled monocentric study.
Traitement de l’acné inflammatoire par laser Erbium:Glass :
Evaluation of the 1,540-nm Erbium:Glass Laser in the Treatment of Inflammatory Facial Acne.Bogle MA, Dover JS, Arndt KA, Mordon S. The Laser and Cosmetic Surgery Center of Houston, Houston, Texas, and SkinCare Physicians, Chestnut Hill, Massachusetts, USA. firstname.lastname@example.org
BACKGROUND : The erbium:glass laser is approved to treat inflammatory acne on the back.
OBJECTIVE : This aim of this study was to evaluate the use of the 1,540-nm erbium:glass laser in the treatment of moderate to severe inflammatory acne on the face.
METHODS AND MATERIALS : An erbium:glass laser (Aramis, Quantel Medical, Clermont-Ferrand, France) was used to treat 15 patients with moderate to severe acne four times at 2-week intervals. Active lesions were first treated with six pulses at 10 J/cm(2). The entire face was then treated with a single pass using bursts of four pulses at 10 J/cm(2). Sebum measurements were performed. Six patients continued in a double-arm study to determine whether an additional treatment at 6 months would prolong the lesion-free period. Final evaluation was at 9 months.
RESULTS At 6-month follow-up, patients rated improvement as 68%, and the mean investigator improvement assessment was 78%. Sebum measurements did not change. No patients required anesthesia, and no side effects were observed. A single retreatment session 6 months after the initial course held clearance at 80% at 9-month follow-up, whereas patients without retreatment had 72% clearance.
CONCLUSION : Treatment of inflammatory facial acne with the 1,540-nm erbium:glass laser is effective and relatively painless. Papules, pustules, and nodules all respond well to therapy. Additional treatment sessions may prolong the lesion-free period, and maintenance therapy should be included as a part of the treatment course.
Evaluation du traitement de la cellulite par technologie elos :
Background Very few therapeutic options have proven effective in the treatment of cellulite.
Aims To evaluate the effectiveness and adverse effects of a bipolar radiofrequency (RF), infrared (IR) heat and pulsatile suction device for the treatment of cellulite.
Methods Twelve subjects were treated with the RF-light-based device. All subjects were treated twice weekly for a total number of eight to nine treatments. Subjects were evaluated using standardized photographs, and measurements of body weight and circumference of treatment sites at baseline, immediately after the last treatment, and four weeks and one year after the last treatment. Clinical improvement scores of comparable photographs using a quartile grading scale (0 = <25%, 1 = 25–50%, 2 = 51–75%, 3 =>75% improvement) were judged independently by two non-treating dermatologists after the series of treatment.
Results The average body weights at baseline, immediately after the last treatment, and four weeks and one year after the complete treatment were 56.30, 56.05, 56.23, and 56.53 kg, respectively. The average circumferential reductions of the abdomen and thigh at the last treatment visit were 5.17 ± 1.04 cm (6.32%±1.82%) and 3.50 ± 2.16 cm(6.23±3.58%), respectively. At four weeks after the last treatment, the average circumferential reductions of the abdomen and thigh were sustained at 3.17 ± 2.75 cm (4.04% ± 3.69%) and 3.50 ± 2.04 cm (6.26% ± 3.52%), respectively. At one year follow-up visit, the average circumferential reductions of the abdomen and thigh were maintained at 3.83 ± 0.76 cm (4.64% ± 1.15%) and 3.13 ± 3.54 (5.50% ± 6.12%), respectively. Average clinical improvement scores of the abdomen and thigh after the series of treatments were 0.75 (corresponding to 25% improvement), and 1.75 (corresponding to 50% improvement), respectively.
Conclusions A bipolar RF, IR heat and pulsatile suction device provides a beneficial effect on reduction of abdomen and thigh circumference, and smoothening of the cellulite. Keywords : cellulite, circumferential reduction, infrared heat, pulsatile suction, radiofrequency.

Détatouage par laser Q-switched :
Dermatology Laser Center, Massachusetts General Hospital, Boston 02114, USA.
BACKGROUND : Many modalities for the treatment of tattoos and pigmented lesions produce a greater risk of complications in Fitzpatrick types V and VI skin because of an increased incidence of adverse pigmentary changes and keloidal scarring. In fair-skinned persons Q-switched lasers have proved effective in removing pigmented lesions and tattoos without scarring.
OBJECTIVE : This study was conducted to determine the efficacy and effects of Q-switched lasers on a small series of darkly pigmented patients with tattoos.
METHODS : Four patients of Ethiopian origin with facial and neck tribal tattoos were treated with both the Q-switched ruby and Nd:YAG lasers. One black woman with a multicolored tattoo on the mid chest was treated with the Q-switched ruby laser.
RESULTS : Clearing of all lesions was seen. The treatments did not result in scarring or permanent pigment changes other than the ones intended.
CONCLUSION : Our results indicate that in darkly pigmented patients, Q-switched laser treatment of tattoos can be performed successfully. The longer wavelength Q-switched Nd:YAG laser is recommended when removing tattoos in darker complected persons. A test treatment is advised before treatment of large skin areas.

OBJECTIVES : To thoroughly review the literature on laser tattoo removal pertaining to its history, its theoretical basis, the various devices used, potential adverse effects, and future developments.
MATERIAL AND METHODS : An extensive literature review of publications related to tattoo removal was conducted.
RESULTS : Reports exist demonstrating the efficacy of laser removal of different tattoo types, including professional, amateur, traumatic, cosmetic, and medical. The literature supports the use of different QS lasers for removal of tattoos. Some colors have a more-complete response using particular wavelengths.
CONCLUSION : QS lasers can effectively and safely remove different types of unwanted tattoos.
Traitement Angiomes rubis et stellaires :
Comparison of potassium titanyl phosphate vascular laser and hyfrecator in the treatment of vascular spiders and cherry angiomas G. Dawn and G.

Patients with vascular spiders and angiomas, especially on exposed sites, demonstrate considerable psychological morbidity and therefore request treatment. Traditionally, electrosurgical modalities have been used to treat such lesions, but more recently lasers have been introduced. This open study assesses the efficacy of these two treatment modalities, scoring patients’ preference and psychological morbidity before and after treatment. All patients had two vascular spiders or angiomas. One lesion was randomized for treatment with the hyfrecator, whilst the other lesion was treated with the potassium titanyl phosphate (KTP) vascular laser. The end-point of the study was either clearance of lesions or a maximum of three treatments at 2-month intervals. In this first comparative study, we demonstrate that both therapeutic modalities were effective in treating these lesions and in significantly reducing the post-treatment psychological morbidity score. However, on average, only one treatment with the KTP laser was required to achieve clearance compared with two treatments with the hyfrecator. This would result in less clinic visits. In addition, patients favoured the KTP laser because of the lack of side-effects. Both the KTP vascular laser and the hyfrecator were able to clear vascular spiders and angiomas, but the KTP laser was superior as fewer treatment episodes were required and patients preferred this treatment modality because of the lack of side-effects.

Traitement des varicosités des membres inférieurs par laser Yag :
TREATMENT OF LOWER LIMBS’S VENULECTASIAS BY YAG LASER.
Publication : Les Nouvelles Dermatologiques Rubrique : Dossier Date : 01/09/2003 Auteur : B. TACK 6, rue Chaussée Ferrée - 14000 Caen
Summary : 1064 nm Nd:Yag laser has been recommended for treatment of venulectasias. Procedures are detailed when laser is performed on lower limbs. Duration is adapted according to the size of the vessel (30-50 ms). Immediate response after the first shot is evaluated by the treating physician : fluence and pulsed duration must be changed if the first shot has no success. Hyperpigmentation is transient. Local complication (blistering) is rare. When clearance of venulectasias is not obtained, a follow-up of 3 months is required and, then, a new session can be performed.
