Becker's naevus: a comparative study between erbium: YAG and Q-switched neodymium:YAG; clinical and histopathological findings.

BACKGROUND: Becker's naevus (BN) may represent a distressing cosmetic handicap and a challenging issue regarding treatment. OBJECTIVES: To compare clinical and histopathological findings of patients with BN treated with two different lasers: an erbium:yttrium-aluminium-garnet (Er:YAG) system vs. a neodymium:YAG (Nd:YAG) laser. PATIENTS AND METHODS: In this prospective and comparative study we present the clinical and histopathological evolution during a 2-year follow-up of 22 patients with BN treated with only one pass of the Er:YAG laser (n = 11) or three treatment sessions with the Q-switched Nd:YAG system (n = 11). RESULTS: Clinical evaluation 2 years after treatment with the Er:YAG laser showed complete clearance (100%) in 54% of the patients (n = 6) and clearance of > 50% in 100% of the subjects. In relation to Nd:YAG laser treatments our results echo those of other authors. Numerous sessions are necessary to get an acceptable clinical clearance rate. Only one patient showed marked clearance (51-99%) after three treatment sessions. Moderate (26-50%) and mild (1-25%) clearance was observed in 45.5% (n = 5) and 27.3% (n = 3) of the patients. CONCLUSIONS: Both Er:YAG and Nd:YAG are safe tools to treat BN. However, in terms of pigment removal, one pass with Er:YAG is a superior technique to three treatment sessions with the Nd:YAG.

Combined nonablative skin rejuvenation with the 595- and 1450-nm lasers.

BACKGROUND: Histologic findings are not echoed in the visible effect in the epidermis after skin rejuvenation. SUBJECTS AND METHODS: Ten women (Group A) received five treatment sessions with a 595-nm pulsed dye laser immediately followed by a 1450-nm diode laser. Two other demographically similar groups of 10 patients each, Groups B and C, were treated with the 595-nm pulsed dye laser or the 1450-nm diode laser alone, respectively. RESULTS: Good dermal collagen remodeling was observed in Group A. Overall better and faster results were seen in Group A. The 6-month clinical outcome was best in Group A followed by Group C and Group B. CONCLUSIONS: Wavelengths of 595 plus 1450 nm for skin rejuvenation produced good results with much higher patient satisfaction than those obtained with the 595- or 1450-nm wavelengths alone.

Treatment of nevus of Ota with the Q-switched alexandrite laser.

BACKGROUND AND OBJECTIVE: Q-switched laser systems have been shown to be useful for removal of nevus of Ota, a pigmented lesion on the face. The purpose of this study was to evaluate the efficacy of Q-switched alexandrite laser in the treatment of nevus of Ota in 13 patients. STUDY DESIGN/MATERIALS AND METHODS: A spot test was made at 6.0, 7.0, and 8.0 J/cm(2) energy fluence, and the best energy fluence was selected after a 2-month postoperative evaluation. Q-switched alexandrite laser with a mean fluence of 7.290.46 J/cm(2) was used at 8-week intervals. Total treatment ranged from 1 to 15 sessions (mean 7.1 +/- 5.1 sessions). The single shot technique was used. RESULTS: More than 75% lightening was achieved in seven patients, between 51% and 75% in three, less than 50% in one, and less than 25% in one. In two patients with excellent clearance, a very light gray macula in the lower eyelid persisted after 8 and 14 treatment sessions, respectively. Mild transient hypopigmentation that subsided spontaneously after 2 months was observed in one patient. No repigmentation was seen. CONCLUSIONS: The Q-switched alexandrite laser seems to be an effective and safe modality for the treatment of nevus of Ota.

Noncoherent-intense-pulsed light for the treatment of relapsing hairy intradermal melanocytic nevus after shave excision.

BACKGROUND AND OBJECTIVE: Few reports about melanocytic lesions treatment by means of noncoherent-intense-pulsed light (NCIPL) have been published. Here we evaluate the clinical results of a relapsing hairy intradermal melanocytic nevus treated with a noncoherent-intense-pulsed light source. STUDY DESIGN/MATERIALS AND METHODS: A facial repigmented hairy intradermal melanocytic nevus that relapsed after shave excision, received four treatment sessions of a noncoherent-intense-pulsed light source (EpiLight, ESC Medical Systems Ltd, Israel) with the following parameters: 755 nm, a fluence energy of 40-42.5 J/cm(2), triple mode, a pulse width of 3.8 ms, and a delay of 20 ms, at 4-week intervals. RESULTS: Complete pigment clearance and hair removal was obtained. We have neither observed repigmentation nor hair regrowth after a 6 month-follow-up. No side effects were documented. CONCLUSIONS: Noncoherent-intense-pulse light is an effective treatment for hairy-pigmented melanocytic nevus.

Necrobiosis lipoidica diabeticorum treated with the pulsed dye laser.

BACKGROUND AND OBJECTIVE: Different treatment modalities have been advocated for necrobiosis lipoidica diabeticorum but clinical response is unpredictable. The purpose of this study was to evaluate the usefulness of pulsed dye laser (Candela SPTL, Irvine, MA, USA) in the treatment of an area of necrobiosis lipoidica of 4 cm in diameter on the anterior aspect of the leg in a non-diabetic patient. MATERIALS AND METHODS: A spot test was made at 6.0, 6.5 and 7.0 J/cm(2) energy fluences and the best energy fluence was selected after a 2-month postoperative evaluation. The patient received three treatment sessions with a fluence of 6.5 J/cm(2), 585-nm wavelength, 5-mm spot size, and 450 micro(s) pulse duration at 8-week intervals. The patient was given routine skin care advice with emollient cream and sunscreen (SPF 15) until the following session. RESULTS: Overall cosmetic improvement was achieved, with a decrease of erythema and telangiectasis, and stabilization in terms of progression (size) in the left half of the lesion, with no modification of atrophy or pigmentary changes. The right upper quadrant of the lesion showed an erythematous peripheral halo with minimal reduction in the erythema and telangiectasia, and discrete size increase. CONCLUSION: Pulsed dye laser may be a useful treatment for improving the telangiectasia and erythematous component of necrobiosis lipoidica.

Second intention healing after Mohs micrographic surgery.

BACKGROUND: Although second intention healing has been used for many years in Mohs micrographic surgery, it has lost popularity. This is due to the long process and functional alteration of important anatomical units if certain wound healing factors are not carefully taken into consideration. OBJECTIVE: To review indications, contraindications, complications, advantages, disadvantages, as well as basic concepts of the wound healing process, wound care and antibiotic prophylaxis in the management of open wounds after Mohs surgery. METHODS: A short but comprehensive review of studies published in the literature dealing with second intention healing as a reconstruction alternative option in certain situations. CONCLUSIONS: Second intention healing is a simple and cost-effective method for reconstruction after Mohs micrographic surgery in well-defined cases. It allows adequate tumoral control with good to excellent functional and cosmetic results.

Corrective photoepilation for improper hairline placement after hair transplantation.

BACKGROUND: Noncoherent filtered flashlamp pulsed light has not been used for correction of surgical problems after hair transplantation. OBJECTIVE: To evaluate the clinical results of photoepilation in a patient with improper hairline placement after hair transplantation. METHODS: A noncoherent filtered flashlamp pulsed light source was used to photoepilate the misplaced frontal hairline in a 37-year-old Caucasian man, skin phototype IV (Fitzpatrick scale), who suffered from common baldness grade IV (Ebling scale) and had undergone a hair transplant 6 years before. The frontal hairline received three treatment sessions at 2-month intervals with the following treatment parameters: 695 nm cutoff filter, fluence 38 J/cm2, 3.5-msec pulse duration, triple-pulse mode, and 30-msec delay. The gulfs received two treatment sessions with the same protocol. RESULTS: Final clinical aspect was good and no hair regrowth in the frontal hairline has been observed after 1.5 years of follow-up. CONCLUSION: Noncoherent filtered flashlamp pulsed light is a novel therapeutic choice that offers a nonsurgical solution to unnatural hairline after hair transplantation.
