OBJECTIVE : To evaluate the response of KPA to treatment with the pulsed dye laser (PDL) with regard to improvements in erythema and skin roughness, treatment tolerability, and side effects. METHODS : Treatment of all facial areas involved with KPA with the PDL at 585 nm was evaluated in 12 patients. Prior to and after each treatment skin erythema was estimated using an erythema meter, and skin roughness was analysed using micrometer evaluation of a skin surface biopsy taken from the same mapped area and anaysed by computer to calculate the roughness profile. RESULTS : Patients received 2 to 8 treatments with the PDL with energies ranging from 6.0 to 7.5 J/cm 2 . Clinical improvement was noted in all patients with significant reduction in erythema scores. Pre-treatment scores ranged from 4 to 13 (mean 8.3) and post-treatment 0 to 8 (mean 3.1) ( P < 0.05). Improvements in skin roughness were clinically apparent in all but two patients, but these were not significant on evaluation of skin surface biopsies. Treatment was generally well tolerated, and side effects other than local pain during treatment were very few. CONCLUSION : PDL treatment appears to be a safe and effective treatment for the erythema associated with KPA but does not give significant improvement in associated skin roughness.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"106 1","pages":"151 - 156"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516416","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798386","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}

Elimination of cosmetic tattoos is sought because of misplacement or migration of tattoo pigment, allergic reactions to the various pigments or dissatisfaction of the customer for various reasons. Removal of unwanted pigment is a domain of laser surgery using various Q-switched laser systems, such as the ruby, alexandrite, pulsed dye and Nd:YAG lasers. Dark colours are easily removed by these lasers, whereas red, pink and skin-toned pigment may turn black if exposed to Q-switched laser light. This ink-blackening occurs because Q-switched lasers heat up the pigments, which consist of ferric oxide, and reduce them into ferrous oxide, which is black. Laser-induced black ink is not always readily removed. A successful ruby laser-removal of laser-induced blackened cosmetic tattoos for acne scar camouflage is reported. The advantageous outcome in this case contrasts with other published cases where laser-darkened pigment had to be removed by other measures, or was permanent. Test site treatment can limit the problem to some degree but, in addition to test-treating, some kind of 'tattoo identification card' could help to prevent problems in this field and allow 'in vitro' test treatment.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"37 - 39"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628830050516597","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798663","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 : This study aims to evaluate two different methods (damp gauze or damp large-tip cotton buds) in order to elucidate their influence on the healing process, if any. The left or right preauricular area, chosen at random on 10 patients undergoing periocular and perioral resurfacing with the same laser system, was cleaned after each laser pass with damp gauze (Group G) and the contralateral side with the large-tip cotton buds (Group C). Post-resurfacing oedema and erythema were observed in the preauricular areas and rated by the same experienced observer immediately after treatment and aggressive cleaning at 14, 30, 45, 60 and 90 days. RESULTS : Oedema was slightly more noticeable initially in Group G patients, but the erythema was more intense and lasted longer in the gauze-cleaned tissue. The sites were biopsied at 90 days and the samples sent for blinded histological evaluation to assess the degree of collagen and elastin fibre compaction. The histology demonstrated that the tissue from Group G achieved, at 90 days, better compaction of collagen and elastin fibres than that from Group C. CONCLUSIONS : It is suggested that the abrasive action caused by the gauze adds to the existing stimulative inflammatory reaction following CO 2 laser resurfacing, which augments the collagen and fibre compaction response in the tissue. Comparatively aggressive cleaning with damp gauze may therefore be preferable to other methods when performing laser resurfacing.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"169 - 176"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/146288300750163736","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798794","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 : Our aim was to evaluate two 800 nm diode lasers (Lightsheer®) with 30 msec and 100 msec pulse durations in the treatment of African American patients with skin types V and VI. Histologic studies, efficacy and side effects were examined in an effort to optimize laser hair removal procedures in this patient population. METHODS : Facial, neck and axillary areas were treated using 800 nm diode lasers at 30 and 100 msec pulse durations with fluences between 15 J/cm 2 and 40 J/cm 2 . RESULTS : Both lasers could be used safely in skin type V and VI African American patients. Longer pulse durations enabled the delivery of higher fluences with minor and acceptable postoperative complication profiles. CONCLUSION : The Lightsheer® diode laser (Coherent Medical, Santa Clara, CA, USA) operating at 30 msec and 100 msec can be safely used in hair removal procedures in African American patients.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"2 1","pages":"183 - 190"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/146288300750163754","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798841","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 treatment eliminates the wrinkles and, ideally, should also recover the aesthetic configuration.\u0000\u0000\u0000METHODS\u0000This report includes 32 patients treated for wrinkles of the upper lip with the Derma K. The first pass was done using 29 J/cm2, 5 Hz, 3 mm collimated spot size, plus the CO2 laser 5 W, 50% duty cycle, 50% overlapping. Following this pass, Derma K was reprogrammed to emit only with the Er:YAG at 1.4 J/cm2, 10 Hz, approximately 50% overlapping and with a beam diameter of 3 mm. Then, several passes were done where wrinkles could still be seen, focusing on the area corresponding to the filtrum. Biopsies were taken to examine possible particular implications of underlying muscle and its role in the recovery of anatomic aesthetics of young lip characteristics when using the proposed technique.\u0000\u0000\u0000RESULTS\u0000Using Derma K resurfacing with extra passes of the Er:YAG at relatively low density, at the aforementioned area, it was possible to achieve the recovery of the aesthetic youthful appearance of the upper lip. Also, the shape of the filtrum recovered its youthful appearance together with the cupid's bow shape. Histology samples collected at the end of resurfacing showed that the laser thermal effect was also related to muscle fibres due to the proximity of this layer to the dermis because of the narrow subcutaneous fat layer.\u0000\u0000\u0000CONCLUSION\u0000The combination of Er:YAG and CO2 laser of Derma K has potential to enhance the results of resurfacing for elimination of wrinkles of the upper lip. Moreover, the fact that only one laser pass of high energy density is used permits clear and secure control of treatment, preventing complications and obtaining good results.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"1 4 1","pages":"225-8"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628839950516715","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59799411","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}
