Flashlamp-pumped pulsed dye laser for port-wine stains in infancy: Earlier versus later treatment

Robin Ashinoff; Roy G. Geronemus

Twelve children, 6 to 30 weeks of age (average 14.9 weeks), with port-wine stains of the head and neck were treated with the flashlamp-pumped pulsed dye laser at 585 nm and 450 microsecond pulse duration. Ten of 12 patients (83%) showed more than 50% lightening of their port-wine stains after 2.9 treatment sessions (2.9 +/- 1.4 [+/- standard deviation]). Forty-five percent of the patients demonstrated 75% or more lightening of their lesions after a mean of 3.8 treatments (+/- 1.6). No lesions in this group cleared completely after a mean of 2.8 treatments. Treated skin was identical in texture to normal skin in all patients. There was no evidence of depressed scars, atrophy, hyperpigmentation, or hypopigmentation in the treated areas. These results indicate that pulsed dye laser treatment of port-wine stains can be undertaken safely in infancy.

Allergic Reactions to Tattoo Pigment after Laser Treatment

Robin Ashinoff; Vicki J. Levine; Nicholas A. Soter

BACKGROUND Cutaneous allergic reactions to pigments found in tattoos are not infrequent. Cinnabar (mercuric sulfide) is the most common cause of allergic reactions in tattoos and is probably related to a cell‐mediated (delayed) hypersensitivity reaction. OBJECTIVE The purpose of these case presentations is to describe a previously unreported complication of tattoo removal with two Q‐switched lasers. RESULTS Two patients without prior histories of skin disease experienced localized as well as widespread allergic reactions after treatment of their tattoos with two Q‐switched lasers. CONCLUSION The Q‐switched ruby and neodymium:yttrium‐aluminum‐garnet lasers target intracellular tattoo pigment, causing rapid thermal expansion that fragments pigment‐containing cells and causes the pigment to become extracellular. This extracellular pigment is then recognized by the immune system as foreign.

Laser Removal of Tattoos

Marina Kuperman-Beade; Vicki J. Levine; Robin Ashinoff

Tattoos are placed for different reasons. A technique for tattoo removal which produces selective removal of each tattoo pigment, with minimal risk of scarring, is needed. Nonspecific methods have a high incidence of scarring, textural, and pigmentary alterations compared with the use of Q-switched lasers. With new advances in Q-switched laser technology, tattoo removal can be achieved with minimal risk of scarring and permanent pigmentary alteration.There are five types of tattoos: amateur, professional, cosmetic, medicinal, and traumatic. Amateur tattoos require less treatment sessions than professional multicolored tattoos. Other factors to consider when evaluating tattoos for removal are: location, age and the skin type of the patient.Treatment should begin by obtaining a pre-operative history. Since treatment with the Q-switched lasers is painful, use of a local injection with lidocaine or topical anaesthesia cream may be used prior to laser treatment. Topical broad-spectrum antibacterial ointment is applied immediately following the procedure.Three types of lasers are currently used for tattoo removal: Q-switched ruby laser (694nm), Q-switched Nd:YAG laser (532nm, 1064nm), and Q-switched alexandrite laser (755nm). The Q-switched ruby and alexandrite lasers are useful for removing black, blue and green pigments. The Q-switched 532nm Nd:YAG laser can be used to remove red pigments and the 1064nm Nd:YAG laser is used for removal of black and blue pigments.The most common adverse effects following laser tattoo treatment with the Q-switched ruby laser include textural change, scarring, and pigmentary alteration. Transient hypopigmentation and textural changes have been reported in up to 50 and 12%, respectively, of patients treated with the Q-switched alexandrite laser. Hyperpigmentation and textural changes are infrequent adverse effects of the Q-switched Nd:YAG laser and the incidence of hypopigmentary changes is much lower than with the ruby laser. The development of localized and generalized allergic reactions is an unusual complication following tattoo removal with the Q-switched ruby and Nd:YAG lasers.Since many wavelengths are needed to treat multicolored tattoos, not one laser system can be used alone to remove all the available inks and combination of inks. While laser tattoo removal is not perfect, we have come a long way since the advent of Q-switched lasers. Current research is focusing on newer picosecond lasers, which may be more successful than the Q-switched lasers in the removal of the new vibrant tattoo inks.

Failure of the Flashlamp‐Pumped Pulsed Dye Laser to Prevent Progression to Deep Hemangioma

Robin Ashinoff; Roy G. Geronemus

Abstract: Hemangiomas are common vascular lesions in children. The flashIamp‐pumped pulsed dye laser has shown excellent results in the treatment of port‐wine stains and, more recently, superficial (capillary) hemangiomas. Four patients with clinically evident superficial hemanglo‐mas illustrate the point that early treatment with this laser may not preclude growth of a deeper component of the lesions.

Rapid response of traumatic and medical tattoos to treatment with the Q-switched ruby laser

Robin Ashinoff; Roy G. Geronemus

Traumatic tattoos can be very difficult to remove. Excision is often not possible because of the extent of the tattoo, and dermabrasion may not be able to reach the area of pigment without significant scarring. Six patients with traumatic (n = 5) or medical (n = 11) tattoos were treated with the Q-switched ruby laser with complete or nearly complete resolution after one to six treatments without cutaneous scarring or permanent pigmentary alteration.

Resistant discoid lupus erythematosus of palms and soles: Successful treatment with azathioprine

Robin Ashinoff; Victoria P. Werth; Andrew G. Franks

We present the case of two patients with an unusual form of discoid lupus erythematosus that was confined almost exclusively to the palms and soles. In both patients this form of discoid lupus erythematosus did not respond to conventional therapies, which included topical steroids, intralesional steroids, prednisone, quinacrine hydrochloride, hydroxychloroquine sulfate, colchicine, and dapsone. Both patients were then treated with azathioprine. One patient dramatically improved with azathioprine, worsened each time the azathioprine was stopped or reduced, and responded again to the reinstitution of therapy. The other patient began taking azathioprine 8 months ago and has also experienced relief of her symptoms. These cases suggest that discoid lupus erythematosus principally involving the palms and soles is difficult to treat with conventional medication and that azathioprine, which appears to be useful, should be tried after the failure of other therapies.

Background. There is no single optimal treatment for multiple facial actinic keratoses. The existing therapies such as topical 5‐fluorouracil, chemical peels, cryotherapy, dermabrasion, and CO2 laser resurfacing can produce prolonged recovery time or are often operator dependent. Objective. The purpose of this study was to investigate another therapeutic modality which provides a shorter recovery time with uniform results. We performed a prospective pilot study investigating the use of the Er:YAG laser for the treatment of multiple facial actinic keratoses. Methods. Five patients with multiple facial actinic keratoses were treated with two to three passes of Er:YAG laser. Anesthesia was achieved in all cases by topical application and local infiltration when indicated. All patients were treated with 2.0 J, 5 mm spot size, and a fluence of 10 J/cm2. Clinical and histologic evaluations were performed both pre‐ and postoperatively. Results. All patients showed a decrease in the total number of clinical actinic keratoses on the face ranging from 86 to 96%. In addition to the reversal of actinic damage in the epidermis, histologic evidence revealed increased fibroplasia and decreased superficial solar elastosis 3 months after the laser resurfacing. Reepithelialization occurred in 5–8 days, and erythema lasted for about 3–6 weeks after the procedure. There was no evidence of scarring or pigmentary changes in any of the patients during the follow‐up period. Conclusion. Er:YAG laser skin resurfacing is a safe and effective treatment for multiple facial actinic keratoses. Histologic data suggest a new zone of collagen deposition occurs in the superficial papillary dermis. Under our current parameters, Er:YAG laser skin resurfacing has a relatively short recovery period and a low risk of scarring. Unlike the CO2 laser, Er:YAG laser skin resurfacing can be performed with topical anesthesia alone.

Elisabeth Shim; Yardy Tse; Elsa F. Velazquez; Hideko Kamino; Vicki J. Levine; Robin Ashinoff

background. Previous studies have shown the efficacy of short‐pulse carbon dioxide (CO2) lasers in the treatment of rhytides and scars. To date, there have been few studies examining the histological aspects of these treatments. objective. The purpose of this study was to perform a prospective clinical and histopathological study of CO2 laser resurfacing for improvement of facial rhytides and scars. methods. A total of 23 patients were studied. Clinical improvement was evaluated both pre‐ and postoperatively using photographs and optical profilometry. Skin biopsies of rhytides were also obtained. results. Postoperatively, rhytides and scars both demonstrated significant increases in clinical improvement scores. Results from optical profilometry studies reflected these results. Skin biopsies from rhytides posttreatment demonstrated increases in collagen layer thickness. Improvement was sustained as late as 1 year following treatment. conclusions. Histopathological studies suggest improvement of rhytides and scars by CO2 laser resurfacing may be attributed to new collagen formation following treatment.

BACKGROUND. Chemical peels using alpha hydroxy acids have become one of the most frequently requested dermaiologic procedures. The use of glycolic acid in superficial chemical peels is now well established. However, the role of glycolic add in medium‐depth chemical peels has yet to be elucidated. OBJECTIVE. We performed a clinical and histologic comparison of 70% glycolic acid versus fessners solution as part of a medium‐depth chemical peel using 35% trichloroacetic acid (TCA). METHODS. Thirteen patients with actinic keratoses, solar lentigines, and fine wrinkling were evaluated praspectively. Each patient was treated with 70% glycolic acid plus 35% TCA (GA‐TCA) to the right face and Jessners solution plus 35% TCA (JS‐TCA) to the left face. Clinical and histologic changes were evaluated at 7, 30, and 60 days postoperatively. RESULTS. Clinically, the GA‐TCA peel was effective in treating photodamaged skin. The GA‐TCA peel was slightly more efficacious in removing actinic keratoses (clinical response score = 1.5) than the JS‐TCA peel (clinical response score = 1.0). His‐tologically, the GA‐TCA peel caused the formation of a slightly thicker Grenz zone (mean = 0.053 mm) 60 days postpeel than the JS‐TCA peel (mean = 0.048 mm) (not statistically significant). The GA‐TCA peel caused more neoelastagenesis than the JS‐TCA peel, while the JS‐TCA peel resulted in more papillary dermal fibrosis and neavascularization than the GA‐TCA peel. CONCLUSION. The GA‐TCA peel is a new medium‐depth chemical peel that is effective in treating photodamaged skin.

Q-switched ruby laser treatment of labial lentigos

Robin Ashinoff; Roy G. Geronemus

The Q-switched ruby laser causes selective damage to pigmented cells in the skin. This laser, which has a wavelength of 694 nm and a pulse duration of 40 nsec, has shown very promising results in the treatment of both amateur and professional tattoos. Less data are available on its ability to treat benign pigmented lesions of the skin. Three patients who had labial lentigos were treated with the Q-switched ruby laser, and dramatic clearing occurred after one or two treatments with a fluence of 10 J/cm2.
