Most patients desiring this treatment are younger and want improvement without any down time. This study was conducted to evaluate the use of Er:YAG laser as a facial rejuvenation tool. METHODS : The full faces of 18 volunteers were treated with an Er:YAG laser using a fluence of either 5 or 10 J/cm 2 . All volunteers applied EMLA ® cream (lidocaine 2.5% and prilocaine 2.5%) two hours before the procedure and were treated with a single pass using a pulse duration of about 300µs. Follow-up visits were made in order to evaluate the degree of discomfort, erythema, swelling and improvement in skin aging. Skin biopsy was performed in one volunteer before and two hours after EMLA ® application, although preceding laser treatment. RESULTS : Most volunteers experienced moderate discomfort during the treatment. There was mild to moderate erythema and mild swelling. The improvement in general skin appearance, actinic bronzing and photo-damage was mild to moderate. The microscopic evaluation of pre-laser treated skin two hours after EMLA ® application was suggestive of increased water content in the dermis. CONCLUSION : The Er:YAG laser is an effective and safe tool for facial rejuvenation. With a superficial treatment, resolution of intense erythema is fairly rapid, averaging two to three days. The improvement, however, is mild compared to full laser skin resurfacing (LSR).","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"119 - 123"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516353","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798223","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}

OBJECTIVE : To determine whether a structured treatment protocol for laser hair removal improves clinical results in reducing hair growth. METHODS : A group of 100 patients (Group A) underwent laser epilation with four regularly spaced treatments; a group of 100 patients (Group B) determined their own treatment plan with respect to timing and frequency (not exceeding four treatments). RESULTS : Group A experienced a 78 - 8% reduction in hair with four treatments per patient while Group B experienced a 48 - 12% reduction with an average of 2.5 - 0.5 treatments per patient. These differences were statistically significant ( P < 0.05). Patient satisfaction was significantly improved in Group A compared with Group B ( P < 0.05). A positive linear relationship was identified in Group B between treatment frequency and hair reduction ( r = 0.94) and between treatment frequency and patient satisfaction ( r = 0.89). CONCLUSION : This study concludes that patients who participate in a structured treatment protocol note superior clinical results following laser hair removal.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"131 - 135"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516371","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798281","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}

Recently, Er:YAG laser resurfacing has proved to be a useful and safe means for several kinds of scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed Er:YAG laser scar resurfacing for the various types of scars induced by trauma, burns, or surgery. METHODS: This study included 36 patients with various types of scars resulting from picking, scratching, knife injury, laceration, car accident, simple surgical excision, focal burn and focal inflammation. Twelve of these patients were treated for hypertrophic scars, 20 for depressed scars, and four for burn scars. The pulsed Er:YAG laser with a 2-mm handpiece at the setting of 500-1200 mJ/pulse at 3.5-9 W was used. Photographs were obtained at baseline and 2-week intervals postoperatively. The results of laser treatment were assessed by two independent physicians and the surgeon according to contour, skin texture and color. RESULTS: In all, 9 of 12 hypertrophic scars, 17 of 20 depressd scars, and two of four burn scars were improved more than 50%. In one patient who had a depressed scar, minimal postinflammatory hyperpigmentation was observed 3 months after laser treatment. Mild erythema was sustained 4 months after laser treatment in one patient with a depressed scar and in all patients with burn scars. No other side effects were observed. CONCLUSION: A pulsed erbium:YAG laser is an effective and safe treatment modality for scar revision.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"27 - 31"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516579","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59799064","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}

Current treatment modalities present various untoward effects and limits. The pulsed dye laser has been considered the gold standard in efficacy and safety; unfortunately it causes postoperative intracutaneous hematomata, discouraging many patients from undergoing this treatment. Several other vascular lasers (argon, tunable dye, copper, krypton, etc.) are disadvantaged by the risk of hypopigmented and atrophic scars. MATERIALS AND METHODS : We assessed a recent powerful version of the potassium titanyl phosphate (KTP) 532 nm laser, which delivers sufficient energy in single pulses lasting 10-50 msec (DioLite 532; IRIDEX, Mountain View, CA, USA). Collateral damage is reduced while the heating of the vessel is slow enough to avoid explosive photothermolysis with its associated purpura. Sixty six patients with facial telangiectasias were treated. RESULTS : In 62/66 patients (93.9%) we achieved a 75-100% clearance of the lesions, while two treatments were needed to reach an acceptable clearance in the remaining 4/66 patients (6.1%). The eventual need for more sessions was well tolerated because the acceptable postoperative appearance allowed patients to continue normal business and social activities between treatments. No permanent complications or undesired effects were noted. CONCLUSION : We conclude that this diode-pumped frequency-doubled Nd:YAG laser is an effective device for the treatment of facial telangiectasias, with a low profile of undesired effects that can be well tolerated by patients.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"141 - 146"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516399","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798333","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}

However, the rate of undesirable side effects is high and sometimes is not warranted by the aesthetic improvement observed. The authors have evaluated the potential benefits of an approach to selective non-ablative wrinkle reduction. MATERIALS AND METHODS: This technique selectively targets the microvasculature which plays a key role in the stimulation of enhanced collagen production. RESULTS: The study reported shows that application of the laser parameters described enhances collagen production by an average of 84%, measured 72 hours after a single laser treatment. This is achieved whilst leaving the skin barrier intact and with no adverse pigmentary changes. The study further shows that a cosmetic improvement is observed with an average value of 1.88 reduction in wrinkle appearance as measured on the Fitzpatrick Wrinkle Severity scale. This improvement was achieved with one brief treatment and no reported incidence of side effects.

However, adverse effects may occur in darker skin patients. Treatment with the ruby laser is generally advised for skin types I-III. Treatment of over 3000 patients (skin types I-III) in our clinic has resulted in a minimal percentage (approximately 3%) of adverse effects. Increasing pulse duration should allow the epidermis to cool and thus minimize thermal damage so that treatment can be extended to dark skin patients. OBJECTIVES: The purpose of our study was to compare tissue reaction in dark skin patients (skin type IV) after treatment with a long-pulse (20 msec) ruby laser and compare the reaction with a 1 msec ruby laser treatment. RESULTS: Hair removal efficacy was determined to be similar with both pulse durations, but tissue reaction was more severe, including eschar and hypo-pigmentation, following treatment of dark skin patients with the 1 msec protocol. Increasing the pulse duration to 20 msec appears to result in safe and efficacious ruby laser treatment even for darker skinned patients.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"17 - 20"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516551","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59799043","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}
