Approximately 30 to 40% of the population suffers from allergic rhinitis during the spring season. Symptoms comprise rhinorrhea, nasal congestion, and sneezing accompanied by irritation and itching of the eyes. The Ohshiro Clinic started using the conventional Nd:YAG laser for the treatment of allergic rhinitis in 1993, and from 2005 we started using a diode laser-pumped Nd:YAG laser. From 2010, we adopted a novel 810 nm diode laser, and the present retrospective study examined the efficacy rate of the treatment of allergic rhinitis in the 2018 season with this system, compared with a previous study in 2011. We aimed to confirm the degree of improvement for each symptom to evaluate effectiveness of the diode laser treatment.</p><p><strong>Subjects and methods: </strong>Between January 8, 2018 and April 30, 2018, a large number of patients consulted our clinic with the major complaint of seasonal allergic rhinitis. They underwent a blood test, and the antigen-specific serum IgE antibody titers were measured for a definitive diagnosis of cedar pollinosis. A total of 211 target patients were treated during the trial period. The average age of the target group was 36.3 years, 134 males, and 77 females. The target patients were treated with lower nasal turbinate mucosal irradiation using a diode laser (ADL-20, Asuka Medical) delivering 810 nm at 7.5 W, with a total energy per treatment of 240 J/cm². We adopted a five-step evaluation in accordance with the Japanese Guidelines for Allergic Rhinitis 2014 for the symptoms of rhinorrhea, sneezing and nasal obstruction. We assessed the degree of improvement in the severity of these symptoms following diode laser treatment from baseline to one month after treatment, in addition to assessing patient satisfaction with the degree of improvement in their quality of life (QOL).</p><p><strong>Results: </strong>The 211 patients positive for cedar pollinosis by the antigen-specific serum IgE antibody tests were broken down by month by number and by improvement, no change or exacerbation as follows. January, 18 patients: 33.4%, 44.4% and 22.2%, respectively. February, 29: 10.4%, 44.4% and 22.2%, respectively. March, 146: 60.3%, 31.5% and 8.2%, respectively. April, 18: 77.8%, 16.7% and 5.5%, respectively. The monthly respective improvement, no change or worse patient QOL as percentages were as follows: January: 16.7%, 44.4% and 38.9%. February: 17.3%, 13.8% and 68.9%. March: 61.6%, 29.5% and 8.9%. April: 94.4%, 0.0% and 5.6%. The values for prevention of exacerbation versus exacerbation for each month were: January, 77.8% vs 22.2%; February, 41.4% vs 58.6%; March, 91.8% vs 8.2%; and April, 94.4% vs 5.6%. The mean efficacy rate for the trial period in the present study was therefore 52.6% which compared very favorably with the mean efficacy rate in the 2011 study of 53.4%.</p><p><strong>Conclusions: </str","PeriodicalId":17981,"journal":{"name":"Laser therapy","volume":"28 1","pages":"11-18"},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5978/islsm.28_19-OR-01","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37047932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Imhof","doi":"10.5978/ISLSM.28_19-CR-01","DOIUrl":"https://doi.org/10.5978/ISLSM.28_19-CR-01","url":null,"abstract":"Background and Aims: Acupuncture has become a substantial part of medical practice in Switzerland. So far, only few cases of accidental tattoo after acupuncture have been reported, which were all caused by acupuncture needles that had been left in the skin and led to local argyrosis. Case: We report the case of a 31-year-old female who developed gray-brown macules after acupuncture. Over 5 months, she had received acupuncture on the same spots one to two times per week and the macules had gradually become darker and had increased in size. The needles used were disposable, contained nickel and were not left in the skin for over 30 minutes. The patient was of Fitzpatrick skin phototype II and showed several grayish-brown macules with an average diameter of around 5mm in the region of glabella, nucha and dorsum pedis. We treated the lesions with a quality-switched ruby laser (694 nm) with a fluence between 3 and 5.5 J/cm 2 , a spot size of 4 or 6 mm and in intervals of 8 to 23 weeks up to a complete elimination of the hyperpigmentation within 11 laser sessions. Conclusion: In synopsis with the anamnesis, the clinical aspect and the therapeutic course, we interpreted the hyperpigmentary spots as a combination of iatrogenic tattooing with nickel and deposition of hemosiderin as well as melanin due to repeated mechanical manipulation and UV exposure of the skin. Furthermore, we hereby show the validity of the quality-switched ruby laser in the removal of accidental hyperpigmentation in skin phototype II.","PeriodicalId":17981,"journal":{"name":"Laser therapy","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71154184","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}
