Background. Acne scar formation is a common consequence of acne vulgaris, in most cases atrophic scars resulting from tissue loss caused by inflammation of the pilosebial units. Aims: To study the effectiveness of combined laser therapy with Nd:YAG laser and Er: YAG laser with autologous plasma with cells in patients with different phenotypes of post-acne atrophic scars. Materials and methods. Depending on the method of treatment of post-acne scars, the patients were divided into 2 groups: Group 1 (n=28) with ice pick scars 10 patients; boxcar 9 patients; rolling 9 patients and group 1 (n=30) among them with ice pick scars 10; boxcar 9; rolling 11 patients. In group 1A, phototherapy was performed using a combination of Nd:YAG laser and Er:YAG laser. Immediately after laser exposure, autologous plasma was applied to the skin of the face of group 1B patients. To assess the effectiveness, the Manchester scale of assessment of scar deformities was used. The effectiveness was also evaluated using the Global Aesthetic Scale (GAIS) on a 3-point system. In this study, cutometry and ultrasound were performed to assess the elasticity of the skin in the foci of atrophy. Results. The indicator "color" on the MSS scale improved in the 1st group by 54.8%, in the 2nd by 83.7%, the indicator "texture" by 57.1 and 78.1%, the indicator "relief" by 43.8 and 66.7%, the indicator "displacement" by 54.9 and 82.1%, respectively. There were no patients with a deterioration or lack of effect on the GAIS scale in any of the study groups. According to the ultrasound scan data, the greatest effectiveness was observed in the group of complex treatment . Conclusion. Complex treatment, including the use of combined laser therapy (erbium and neodymium lasers) and autologous plasma with cells, is a highly effective technique for the treatment of atrophic post-acne scars.

Background. Infantile hemangiomas are revealed in 1-3% of newborns and 10-12% of infants. There are only anecdotal reports on the laser therapy efficacy in this pathology management. However, there is no common approach to the use of this method in the complex treatment of infantile hemangioma in infants. Clinical Cases Description. Two clinical cases of infantile hemangioma are presented. Patients underwent complex treatment: systemic propranolol and laser therapy via pulsed dye laser. Laser exposure modes ware selected individually: laser spot sizes were 10 and 12 mm, energy levels were 5-10 J/cm2, burst duration was short (0.45 ms) or long (10-20 ms), procedure duration was from 15 to 40 minutes, number of procedures varied from 1 to 8. Laser therapy has shown its efficacy in treatment of superficial infantile hemangioma. Conclusion. The indication for using laser therapy in management of infants with hemangiomas is especially persistent residual signs such as telangiectasias and erythema after spontaneous or drug involution phase. Laser therapy allows us to avoid aggressive methods and improves the quality of life of our patients according to this article.

Objective: to studythe effectiveness of autologous plasma-cell microneedling in patients with different phenotypes of post-acne atrophic scars. Group 1A (n = 32) included patients with post – acne atrophic scars: ice pick – 12 patients; boxcar – 11; rolling – 9 patients. Group 1B consisted of 34 patients with scars ice pick – 12; boxcar – 12; rolling – 10 patients. In group 1A, patients underwent a microneedling procedure. In group 1B, microneedling was performed with autologous plasma with cells. To evaluate the effectiveness of the therapy methods, we used the IGA (Investigators Global Assessment) scale modified for post-acne scars, adapted for post-acne scars by the Assessment of the Psychological and Social Effects of Acne (APSEA). Special methods included ultrasound examination using an ultrasound scanner IU 22. The end result for different post-acne scar phenotypes showed the advantages of the developed complex for boxcar and rolling AR and slightly lower for ice pick. The recommended course of therapy is three procedures performed once in 4 weeks.

Aim. To determine the influence of magnetoinfrared laser therapy on the status of immunological reactivity in children with chronic pyelonephritis (CP). Materials and methods. One hundred thirty children aged 8 to12 years, suffering from relapsing course of chronic pyelonephritis, were observed. Group 1 (43 patients) received complex conventional therapy, group 2 (27 patients) – complex treatment, associated with magnetoinfrared laser therapy. The blood lymphocyte population and subpopulation, blood serum immunoglobulin and circulating immune complexes content, phagocytosis indices, blood serum cytokine content was studied in children with chronic pyelonephritis at the active stage of disease, at the partial and full clinicolaboratory remission stages. Results. The CP patients of group 1, who received complex conventional therapy, demonstrated a full, but not long clinicolaboratpory remission with preservation of marked changes in immunological reactivity parameters. In CP patients of group 2, who experienced complex treatment associated with magnetoinfrared laser therapy courses, there occurred full clinicolaboratory remission and normalization of immunological reactivity indices. Conclusions. The results of clinical observations and special studies demonstrate high clinical, immunomodulating and antirelapsing effects of complex treatment combined with magnetoinfrared laser therapy in children with chronic pyelonephritis.

This study aimed at evaluating the influence of EDTA, Nd:YAG laser and the combination of both for filling of artificial lateral root canals. Forty-five human mandibular premolars were employed, on which three artificial lateral root canals were prepared by means of a reamer with a similar diameter to a K file #15. The teeth were instrumented through the stepback technique employing Gates Glidden burs at the middle and cervical thirds and manual files at the apical portion, and irrigation with 1% sodium hypochloride. The teeth were divided in three groups: Group 1 -EDTA for 5 minutes; Group 2 -application of Nd:YAG laser at 15 Hz, 100 mJ and 1.5 Watts; and Group 3 - association of both. Roots were filled through the Tagger's hybrid technique, radiographed and the radiographs were digitized. Scores were assigned to the filling of the lateral root canals. Statistical analysis revealed no significant differences between the entire groups and also on the analysis of each third.

The aim: The purpose of research is to improve the effectiveness of treatment by applying laser in complex treatment in patients with herpetic stomatitis. Materials and methods: Were examined 47 people (22 men and 25 women) with acute herpetic stomatitis. The patіents’ age was from 20 to 72 years. All patients underwent immunological tests such as (T-lymphocytes (CD3 +), T-helpers (CD4 +), cytotoxic T-lymphocytes (CD8 +), the content of immunoglobulins IgM, IgG, IgA and slgA in saliva to assess the іmmunological reactivity of the organism. Results: Clinical observations have shown that when using laser therapy, the results of treatment were better than in the control group. Positive dynamics was observed as early as 1-2 days after the start of laser use and was more pronounced when used in the early stages of the disease. The use of the laser promoted a more rapid suspension of new lesions, a decrease in pain syndrome, and a more rapid regression of herpetic lesions. We have found significant improvements in the arameters of cellular and humoral іmmunity in patients of the main group. Conclusions: Treatment of herpetic stomatitis is relevant and requires further improvement and the search for new methods. The use of a laser in the complex treatment of herpetic stomatitis has a positive effect on the course and іmmunological status of patients with herpetic stomatіtis. The manifestations of the disease healed faster, and the pain syndrome was less severe. Duration between іllness and treatment decreased on 19.7% and 26%. It is advіsable to include the method of treatment using a laser in the complex therapy of herpetic stomatitis.

PURPOSE: To develop an experimental model to be used in the study of low level Laser therapy on viability of random skin flap in rats. METHODS: The sample was 24 Wistar-EPM rats. The random skin flap measured 10 x 4 cm and a plastic sheet was interposed between the flap and donor site. Group 1 (control) underwent sham irradiation with diode laser (830 nm). Group 2 was submitted to laser irradiation with diode laser (830 nm). The animals were submitted to Laser therapy with 36 J/cm² energy density (72 seconds) immediately after the surgery and on the four subsequent days. The probe was usually held in contact with the skin flap surface on a point at 2.5 cm cranial from the flap base. On the seventh postoperative day, the percentage of necrotic area was measured and calculated. RESULTS: Group 1 reached an average necrotic area of 48.86%, Group 2 - 23.14%. After the statistic analysis, compared with the control group, Group 2 showed a statistically significant increase in survival area (p<0.001). CONCLUSION: The experimental model proved to be reliable to be used in the study of effects of low level laser therapy in random skin flap in rats.

Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser may cause intraocular lenses (IOLs) damages. Therefore, the effects of Nd:YAG laser on IOLs were evaluated. Twenty-four IOLs (copolymer of 2-hydroxyethylmethacrylate and 2-ethoxyethylmethacrylate) were used. For scanning electron microscope (SEM), twelve IOLs were divided into three groups: Group 1, controls; Group 2, IOLs treated with two laser spots (YC-1800 Nidek Nd:YAG laser set at 1.2 mJ); and Group 3, IOLs treated with six laser spots. All IOLs were critical point dried in CO2 and viewed in a Zeiss EVO LS10 SEM. For Energy Dispersive X-ray spectrometry (EDX), four IOLs of each group were examined with a Jeol JMC-6000 SEM. With SEM, Group 1 IOLs showed well-preserved size, shape and surface. Group 2 IOLs exhibited normal shape and margins, a peripheral furrow with irregular blebs, straight clefts and holes on the wrinkled surface. Group 3 IOLs were swollen and broken into two or three parts. With SEM and EDX, Group 1 and the undamaged surfaces of Groups 2 and 3 showed evident carbon and oxygen peaks, while, in the damaged areas, both atoms were significantly reduced. Nd:YAG laser induced evident changes in IOLs morphology and organic alterations in their chemistry: great care during posterior capsule opacification treatment is required.
