The “know-how” of Russian excimer laser manufacturers allows to significantly reduce corneal tissue overheating during TransPRK surgery. A new approach to TransPRK surgery consists in simultaneous use of Platoscan program, age nomogram and size of epithelium initial thickness.Purpose: to assess functional outcomes and changes in the corneal epithelium thickness after TransPRK surgery in patients with myopia in the period from 1 month to 1 year.Material and methods. Sixty-six eyes of 33 patients were included in the trial. Average patients’ age was 25.6 ± 6.8 (mean 17–40); 18 men and 15 women. The average spherical component was –2.57 ± 1.54 diopters (from –0.75 to –5.75). The average cylindrical component before surgery was –0.79 ± 0.71 diopters (from 0.00 to –3.5); 45 eyes with mild myopia, 21 eyes with moderate myopia. Epithelium thickness was measured with RTVue-xR Avanti device (Optovue, USA). Calculations were made using Platoscan program and age nomogram (OOO “Opto-systems”, Russia). Assessment of functional outcomes was made using generally accepted standards in refractive surgery.Results. TransPRK has shown its high efficacy, safety, predictability and accuracy in patients with myopia correction. Analysis of OCT findings of the anterior segment using epithelial maps showed that there is no complete restoration of epithelium thickness both in cornea center and in cornea periphery in 7-mm zone by the end of the first month after TransPRK surgery. In one month after TransPRK, epithelium thickness restored by 86.64 % in the center and by 87.99 % in 7-mm zone. Complete restoration of epithelium thickness in the center and in periphery was reached in 6 months. Corneal epithelium thickness in the surgical field increased by 7.9 % both in the center and in periphery in 12 months after the surgery. The ratio of epithelium initial thickness in the center and in periphery to the total cornea thickness before and after the surgery was 10–12 % for the entire study period.","PeriodicalId":10008,"journal":{"name":"Chinese Journal of Laser Medicine & Surgery","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82393829","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}

Material and methods. The experiment was conducted on 96 white male laboratory rats of the Wistar breed. Animals were divided into four groups: 1 – control young, 2 – control old, 3 – young, low-intensity laser irradiation, 4 – old, low-intensity laser irradiation. A single laser irradiation session in continuous mode (wavelength – 970 nm, power – 1 W, exposure – 60 s) was made in the projection of thyroid gland. The animals were removed from the experiment 1 hour and 1, 3 and 7 days after exposure to laser light. Thyroid preparations were fixed in the formalin; histological sections were prepared and stained with toluidine blue; the morphometric analysis was performed to determine the number of thyroid mast cells and their varieties depending on the granular saturation level and degranulation degree.Results. The reaction of thyroid mast cells of experimental animals to laser exposure had some specific features: in young animals there was the increase in the number of cells and in their synthetic activity with the increase in granular saturation level and with the decrease in degranulation level which indicates an increased migration of cells into the thyroid gland and a pronounced adaptive reaction of the entire population of mast cells of the body. In old animals, exposure to laser light caused degranulation activity of thyroid mast cells with decrease in the level of granular saturation. No changes in the number of cells indicates that the reaction is limited within the organ contours.Conclusion. The results obtained expand our understanding of specific reactions of mast cells to laser exposure and confirm the need for individual correction of low-level laser therapy depending on age.","PeriodicalId":10008,"journal":{"name":"Chinese Journal of Laser Medicine & Surgery","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86987476","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 article presents a retrospective analysis of outcomes after treatment of 76 patients with diabetes mellitus having purulent-necrotic lesions in their lower extremities. Patients were divided into two groups. The first (main) group consisted of 34 patients in whom traditional treatment was accompanied by intravenous laser blood irradiation and local laser therapy; the second (control) group consisted of 42 patients who received only traditional treatment.Results. Laser therapy contributed to more rapid reduction of wound defect (17.4 %) compared to patients after traditional treatment (11.1 %); it reduced the period of transition to inflammatory-regenerative changes, promoted a smaller number of high amputations of lower limbs from 14 to 6 % as well as shortened the length of hospital stay by 11.2 days.Conclusion. Laser light therapy in patients with diabetic foot accelerates cleansing and reduction of the wound area, allows to reduce or eliminate inflammatory process in shorter time than with traditional treatment.","PeriodicalId":10008,"journal":{"name":"Chinese Journal of Laser Medicine & Surgery","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84221813","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}

Despite the improvement of surgical techniques, the rate of relapses of the disease remains high. The search for alternative methods of treatment is relevant.Purpose. To evaluate safety and effectiveness of intraoperative photodynamic therapy of sarcoma in soft tissues.Material and methods. Forty-four patients with soft tissue sarcoma were included in the study. Patients were divided into three groups. Group 1 (n = 10): soft tissue sarcoma of stage T2-3N0M0G1, surgical treatment and intraoperative photodynamic therapy. Group 2 (n = 17): soft tissue sarcoma of stage T2-3N0M0G2-3, surgical treatment and intraoperative photodynamic therapy. Group 3 (n = 17): soft tissue sarcoma of stage T2-3N0M0-1G2-3, combined treatment – preoperative light therapy, surgical treatment, intraoperative photodynamic therapy, neoadjuvant and adjuvant chemotherapy. Fluorescence spectrometry was performed to determine the degree of photosensitizer accumulation in tumor tissue. Treatment methodology: photosensitizer was injected 2.5–3 hours before the surgery. The tumor was removed with resection of adjacent muscles and healthy tissues. Then, laser irradiation of the tumor bed was made using “Latus” device. Radiation power was up to 2,5 W, power density was up to 0,28 W/cm2, radiation dose was up to 100 J/cm2. Follow-up ranged from 14 to 44 months.Results. The spectrometry has revealed that photosensitizer was accumulated predominantly in tumor tissue. There were no reactions to photosensitizer injection, no changes in the tumor bed as well as no increase in wound healing period after intraoperative photodynamic therapy.Within the observation period, all patients stayed alive. Relapses of the disease were registered in 38.7 % of patients: in Group 1 – 30 %, in Group 2 – 35.3 %, in Group 3 – 53 %. Of the 20 patients with primary diagnosed neoplasms, relapses were seen in 30 %. Of the 24 patients with previously recurrent neoplasms, 45.8 % had repeated relapses.Conclusion. Intraoperative photodynamic therapy is a safe and effective technique for treating soft tissue sarcomas; it is also the promising direction for research. A small number of observations, a variety of histological forms and stages of the disease make it difficult to assess the effectiveness of the discussed approach. Further studies of intraoperative photodynamic therapy are required.","PeriodicalId":10008,"journal":{"name":"Chinese Journal of Laser Medicine & Surgery","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84850267","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}
