3383. Mathematical modeling of laser lipolysis Full Text available with Trip Pro

Mathematical modeling of laser lipolysis Liposuction continues to be one of the most popular procedures performed in cosmetic surgery. As the public's demand for body contouring continues, laser lipolysis has been proposed to improve results, minimize risk, optimize patient comfort, and reduce the recovery period. Mathematical modeling of laser lipolysis could provide a better understanding of the laser lipolysis process and could determine the optimal dosage as a function of fat volume (...) laser or 980 nm diode laser: (6 W, back and forth motion: 100 mm/s) give similar skin surface temperature (max: 41 degrees C). These measurements are in accordance with those obtained by mathematical modeling performed with a 1 mm cannula inserted inside the hypodermis layer at 0.8 cm below the surface. Similarly, the fat volume reduction observed in patients at 6-month follow up can be determined by mathematical modeling. This fat reduction depends on the applied energy, typically 5 cm3 for 3000 J

3384. Periocular Laser Complications Full Text available with Trip Pro

Periocular Laser Complications Laser periocular surgery has achieved an increased popularity, particularly since the widespread use of CO(2) and erbium:yttrium aluminum garnet laser and more recently with the development of nonablative laser technology. The main target of these techniques is to treat photoaging changes to obtain a rejuvenated skin. Despite the relatively safety of these procedures on experienced hands, postoperative complications affecting the periocular region, and the eye (...) itself, may follow laser surgery. More common complications include persistent erythema, hyper- and hypopigmentation, and hypertrophic scarring. Viral, bacterial, or fungal skin infections may also jeopardize the postoperative period after periocular laser treatment. Severe burns, transitory or permanent lower lid ectropion, and even corneal injuries or ocular perforation are among the most severe hazards. The majority of these complications are related to the use of ablative technologies

and efficacy of combination PDT with topical 5-aminolevulinic acid (ALA) and activation by long-pulsed, pulsed dye laser (LP PDL, 595 nm) energy with topical therapy in patients with mild to severe acne.A prospective, controlled pilot, proof-of-principle study of 19 consecutive patients (aged 16-47 years, Fitzpatrick skin types I-VI) with mild to severe cystic, inflammatory, or comedonal acne of the face was conducted. All patients had failed conventional therapy, including oral antibiotics, topical (...) treatments, hormonal therapy, laser procedures (without ALA), and/or oral isotretinoin. Fifteen patients were treated with ALA PDT and 4 patients served as controls; all were continued on topical medications. Patients undergoing PDT were initially randomized to receive either blue light or laser energy. Because recrudescence occurred in 1 patient while undergoing multiple treatments with ALA and blue light, all subsequent patients were treated with ALA and laser energy. The total number of patients

3388. Digital image enhancement for in vivo laser scanning microscopy. (Abstract)

Digital image enhancement for in vivo laser scanning microscopy. In vivo confocal laser scanning microscopy (CLSM) is a new method that provides skin images in horizontal plane at a level of resolution that allows to view microanatomic structures. This study examines whether certain digital image-processing steps can increase the visibility of various structures in CLSM.Fifty images were taken from normal skin of 25 probands, and 39 image enhancement procedures were created. Eight procedures (...) that seemed to provide some quality enhancement were deliberately selected for further evaluation. Subsequently, a collection of random pairs of the original image and an image submitted to any of the eight selected procedures was rated by five independent observers.In three of the eight procedures tested, the modified image was significantly preferred to the original image (chi2-test,: P< or =0.001).

3389. The effectiveness of PUVA treatment in severe psoriasis is significantly increased by additional UV 308-nm excimer laser sessions. (Abstract)

The effectiveness of PUVA treatment in severe psoriasis is significantly increased by additional UV 308-nm excimer laser sessions. In most cases, patients with moderate to severe psoriasis are treated with narrow-band UVB phototherapy or with psoralen UVA (PUVA-) photochemotherapy. This UV-radiation is given to the whole skin, including unaffected skin. Normally, these two PUVA- and UVB-radiation procedures cannot be combined on account of the phototherapeutic side-effects on unaffected skin (...) . The 308-nm excimer laser has been shown to be safe and effective in the treatment of localized mild-to-moderate plaque-type psoriasis whilst sparing healthy skin. Our aim was to compare the therapeutic response to PUVA plus up to 4 UVB308-nm radiations and PUVA monotherapy in patients with moderate-severe plaque-type psoriasis. 272 hospitalized adult patients were enrolled on this prospective random study. 256 patients completed the full course of treatment. PUVA treatment was given 4 times weekly

A Pulsed Dye Laser with a 10-mm Beam Diameter and a Pigmented Lesion Window for Purpura-Free Photorejuvenation. In traditional pulsed dye lasers (PDLs), power limitations and pulse characteristics have compromised purpura-free procedures. This study evaluated a new PDL with a modified pulse structure and a 10-mm beam diameter for purpura-free photorejuvenation. A compression handpiece was used for targeting lentigines.Twenty patients with skin types I to III were treated three times at 3- to 4 (...) of fine telangiectasias (<0.6 mm) and dark lentigines was achieved. Pigmented dyschromias improved proportional to the degree of pigment at presentation. Avoidance of purpura with the compression handpiece was dependent on obtaining proper compression before laser emission. Mean textural improvement was 34%.The new 595-nm PDL is highly effective for two-pass purpura-free improvement of telangiectases, pigment dyschromias, and texture.

3398. Biological and clinical aspects in laser hair removal. Full Text available with Trip Pro

Biological and clinical aspects in laser hair removal. In the past century, unwanted hair has been traditionally treated with multitudes of techniques that were found to be slow, tedious, painful, impractical, and resulted in poor long-term efficacy. Consequently, there has been a public demand for a novel, rapid, reliable, safe, and affordable hair removal technique. In the last decade, laser and light-based technology for hair removal became one of the fastest growing procedures in modern (...) cosmetic dermatology.To discuss the latest scientific and clinical issues in the field of photoepilation as evolved in the past decade: hair biology, laser physics and skin optics, technology and clinical experience.From substantial clinical experience, it becomes apparent that in the ideal subject with fair skin and dark hair, a single treatment can reduce hair by 10-40%; three treatments by 30-70%; and repeated treatments by as much as 90%. These results persist for as long as 12 months. Diffuse

Paradoxical hypertrichosis after laser epilation. Hair removal using lasers or broadband intense pulsed light has become one of the most ubiquitous medical procedures. At our center a small proportion of patients have spontaneously reported what they believed to be increased hair growth at sites of previous laser epilation. We sought to retrospectively review the prevalence and features of this paradoxical effect.This was a single center, retrospective study that included all patients who (...) ).Of 489 patients, 3 (0.6%, 95% confidence interval: 0.01-1.9%) treated with the long-pulsed alexandrite laser (755 nm) reported increased hair after laser hair epilation. There was a trend for this adverse effect to occur in darker skin phototypes (IV) and with black hair as compared with the unaffected comparison group (n = 50). However, the small number of cases (n = 3) did not provide sufficient power to adequately test factors such as age, sex, treatment settings, and number of treatments

Hair induction after laser-assisted hair removal and its treatment. Laser hair removal is a relatively safe procedure with limited side effects. Hair induction has been previously scarcely reported.We sought to report the incidence of this strange side effect in a large number of patients treated for hair removal and to follow its course and treatment.We conducted retrospective analysis of the files of all patients who underwent laser hair removal during the time period from May 1998 until May (...) 2005 in a private institution in Athens, Greece.Hair induction occurs predominantly on the face and neck of female patients of Mediterranean ancestry with darker skin types. The percentage is quite low (4.5%). Laser treatment of the induced hair reduces the problem.No control groups could be obtained in this study. Furthermore, the natural course of hair induction could not be studied because it was always treated or patients were lost to follow-up.Hair induction is a rare side effect of laser hair
