Thanks to a pulse shorter than the hair Thermal Relaxation time (TRT), photothermolysis was thus achieved. METHODS : This study assessed the percentage of hair reduction at 1 month and at 3 months after a single Nd:YAG laser treatment (Athos; Quantel Médical, France); 3.5 ms pulse, single shot to 3 Hz, a maximum fluence of 80 J/cm 2 , 4 mm spot, no cooling system, no anaesthesia. The treatment sites consisted of three adjacent squares (optimum fluence, no treatment, -20% optimum fluence). Computerized hair counting was realized on digital pictures. The phototype, pain, side effects and patient's satisfaction were noted. Biopsies were performed 15 min after treatment. The enrolment consisted of 17 women, 22-60 years old, phototypes I-IV, with a follow-up at 1 month and 3 months of 25 sites. RESULTS : Counting at 1 month and at 3 months revealed a significant hair reduction compared with the control sites: 60% at 1 month ( P < 0.001) and 24% at 3 months ( P < 0.05) for optimal fluence (25-80 J/cm 2 ), compared with 31% and 0% on the control sites; values similar to those published for Nd:YAG or diode lasers. There were no adverse effects at all. Biopsies showed lesions from necrosis coagulation of the root sheaths and hair disruption to isolated apoptotic cells in the outer root sheath, depending on the fluence applied. CONCLUSION : Results from this study show that the Athos Nd:YAG is efficient and safe for removing pigmented hair in phototypes I-IV.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"125 - 130"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516362","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"IPL sources and ruby lasers for hair reduction - trying to compare apples and oranges","authors":"C. Chess","doi":"10.1080/14628830050516434","DOIUrl":"https://doi.org/10.1080/14628830050516434","url":null,"abstract":"Drs Bjerring et al are to be congratulated for their report on their research entitled ‘Hair reduction using a new intense pulsed light irradiator and a normal mode ruby laser’. This group of studies demonstrates this new intense pulsed light (IPL) source to be nearly four times as effective as the ruby laser. By using the two sides of the face and neck to compare these two light sources one would anticipate meaningful results. Unfortunately, this comparison of broadband irradiation (IPL) and monochromatic ruby laser irradiation is signiŽ cantly  awed, and the results may indeed contribute to an erroneous conclusion. This  aw relates to the choice of a ruby laser that delivers a small spot size (5 mm) being compared to an IPL source with a spot size of 48 3 10 mm. This means that the IPL foot print is 24 times larger than that of the ruby laser. Larger spot size translates to deeper penetration of light which is of distinct importance when we are targeting hair follicles. If we would like to attribute greater effectiveness to the IPL, with its longer wavelengths, then we should have a more even playing Ž eld relative to spot size. Additionally, the authors point out that the ruby laser in their study had a sub-optimal pulse width of less than 1 millisecond. We have learned that in the pursuit of permanent hair reduction, longer pulse widths are beneŽ cial. Hence, the design of this new IPL source included pulse widths from 5–40 milliseconds. Furthermore, this new IPL source enlists the beneŽ t of photon recycling which is absent in the older ruby laser used in this study. Therefore, even though the  uences utilized were nearly identical, photon recycling would enhance efŽ ciency at any wavelength. To summarize, although good control exists by virtue of comparing two similar anatomical sites on the experimental subjects, the absence of controls for spot size, pulse width, and photon recycling disallows any conclusion that broadband irradiation is more effective than monochromatic ruby laser irradiation for permanent hair reduction. Such an erroneous conclusion  ies in the face of our understanding that there is better melanin absorption of 694 nm light than of the longer wavelengths that are part of the emission spectrum of this IPL source. As it happens, there is a ruby laser of more recent design than the one used in this study. Palomar’s E-2000 ruby laser delivers a spot size with four times the area of the Epitouch, with a more appropriate pulse width of 3 milliseconds with an option to pause for 100 milliseconds mid-pulse, and with photon recycling. The one drawback of the ruby laser for hair removal relates to epidermal heating due to the epidermal melanin absorption of 694 nm light. The E-2000’s design therefore, includes a saphire contact cooling tip to minimize the chance of epidermal damage. I would suggest that by comparing the Elipse Relax light 1000, a newly designed IPL source, with a more recently designed normal mode ruby laser","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"161 - 161"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516434","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of our discipline has been once more conŽ rmed by the large number of participants at this event and by the two extremely well-attended core EADV programme courses organized by ESLD: ‘Dermatological Laser 2000: State-of-the-Art’ and ‘Skin Resurfacing’. The excellent organization and the high level of all the presentations brought ESLD and the course directors a great and well deserved success. Maurice Adatto and Denis Salomon were responsible for the ‘State-of-the-Art’ course while Alina Fratila chaired the ‘Skin Resurfacing’ course. For the Ž rst time we were able to offer an interactive video transmission of laser treatments and this extremely useful feature was very well received by the audience. We were also very proud to collaborate with the American Society for Laser Medicine and Surgery (ASLMS) in the spirit of internationalization of scientiŽ c knowledge, which constitutes a fundamental stone of our statutes. The format of the ESLD Annual Meeting, entitled: ‘Dermatological Lasers: 2000 and Beyond’ followed a well tested, traditional sequence of headings. The pigmentspeciŽ c lasers session stimulated a very productive discussion after the exhaustive and elegant presentations offered by Nicholas Lowe, Michael Drosner, Agneta Troilius and Peter Bjerring. Congenital nevi are still considered a mineŽ eld for laser treatments and no ofŽ cially approved experimental treatment protocols have so far been proposed. Although data exist around the world, many physicians using lasers on nevo-melanocytic lesions do not report them. More studies are therefore necessary to Ž nd a deŽ nite answer to this never-ending story. We all agreed about the term ‘hair growth control’ when talking about photo-assisted epilation and the long lasting, virtually complication-free, positive results obtained using long pulse laser systems, and IPLS conŽ rmed the undisputed place of these devices within our treatment armamentarium. Excellent clinical results have been presented on traumatic tattoos, even though multiple sessions are necessary to obtain a good clearing of the extrinsic dermal pigment. Lasers hold a solid position in this particular clinical Ž eld. Reactive pigmentations, on the other hand, seemed to respond unpredictably to laser treatments and clearly better results have been reported using different treatment modalities. The session dedicated to vascular-speciŽ c lasers pointed out again the limitation of laser treatment of acquired lower leg telangiectasias, although more recent technical advances are showing promising short and long-term results. New hope for resistant port wine stains has been brought by the good results reported by Agneta Troilius combining a long pulse 532 nm laser and IPL system. The latest technological achievements of extra-long-pulse dye lasers will certainly co","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"199 - 210"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/146288300750163781","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A wide variety of treatments, all in current usage, indicate that no treatment has been shown to be markedly superior to the others. Following the successful treatment of scars using the pulsed dye laser, and with the more traditional intralesional steroid injection, a pilot study was undertaken using a combination of these treatments. METHODS : Recalcitrant keloid scars of 10 patients were managed with a combined treatment modality of pulsed dye laser (PDL) and intralesional steroid. RESULTS : Seven of the patients benefited in terms of the raised nature of the scars being improved by 60%, erythema improved by 40%, and pain/itching by 75%. Three of the patients, who had presternal scars, had no benefit. CONCLUSIONS : Pretreatment with PDL facilitated steroid injection by making the scar oedematous and therefore softer.
