Relevance. It is currently relevant to study and compare the effectiveness of the autologous connective tissue grafts and the combination of collagen-based and autologous platelet-rich plasma in the surgical treatment of Miller Class I gingival recessions.Materials and methods. We examined and treated 48 (20 male (41.67%) and 28 female (58.33%)) patients aged from 25 to 40 years with Miller Class I gingival recessions. All gingival recessions were treated surgically using a modified twolayer tunnel technique. The patients were divided into two groups according to the graft type. Group I (24 patients (50%) had a connective tissue graft from the hard palate. Group II (24 patients (50%) used the combination of the autologous platelet-rich plasma and 3D collagen matrix Fibromatrix for the regeneration of oral soft tissues. We removed the sutures on the 14th day. The patients were followed up on the 7th and 14th days and in 1.3 months.Results. 48 Miller Class I gingival recessions were treated between 2018 and 2020. The depth of gingival recessions averaged 3.5 ± 1.13 mm before treatment. The level of the attached keratinized gingiva regarding the cementoenamel junction significantly (p < 0.001) improved in both groups after the surgery. The width and thickness of the keratinized gingiva best increased in group II. The mean effectiveness of gingival recession treatment was 84% in study group I and 96% – in study group II. Pain syndrome, fibrinous plaque and soft tissue edema were insignificant in group II.Conclusion. The combination of the autologous platelet-rich plasma and Fibromatrix, collagen 3D matrix, for the regeneration of the oral soft tissues is a more effective technique for the treatment of Miller Class I gingival recessions. This technique has several advantages. It is minimally invasive, less painful, soft tissue postoperative swelling is less and the received volume of the attached keratinized gums is larger than with a connective tissue graft.

Abstract Background and aim Chronic otitis media is defined as a chronic inflammation of the middle ear cleft producing irreversible pathological changes. The myringoplasty aims at the reconstruction of the tympanic membrane using a graft material. Autologous platelet-rich plasma can be used along with the graft to have a successful outcome. The aim of the study was to assess the efficacy of autologous platelet-rich plasma on graft uptake in myringoplasty. Methods This was a randomized controlled trial with a sample size of 76 patients. All patients were above 18 and below 55 years of age diagnosed with chronic suppurative otitis media and were planned for myringoplasty. The participants were randomly allotted to two groups by block randomization (block of 4). Intra-operatively, group I (n=38) received platelet-rich plasma–soaked gel foam and group II (n=38) was taken as the control group who received saline-soaked gel foam and examined by a blinded examiner at the end of 1st and 3rd months. Results The mean air-bone gap reduction post-operatively in the platelet-rich plasma group was 8.68 ± 4.8 (P value 0.034) and 6.05 ± 4.05 in the control group. The improvement in pure-tone average in the platelet-rich plasma group (P = 0.009) is more than that in the control group. The graft uptake was higher among the platelet-rich plasma group than the control group both at 1st and 3rd months (P value 0.049) which were statistically significant. Conclusion The present study concludes that the usage of platelet-rich plasma in the conventional myringoplasty technique has improved the success rate of graft uptake and reduced the graft migration. Trial registration Clinical Trials Registry-India (ICMR-NIMS) CTRI/2020/04/024416. Date of registration: 01/04/2020. Date of enrolment of the first participant to the trial: 06/04/2020. URL of the trial registry: http://www.ctri.nic.in. Highlights Usage of autologous platelet-rich plasma (PRP) in conventional myringoplasty in underlay technique. Assessment of graft uptake, percentage of perforation closure, and the audiological outcome. Significant mean reduction of ABG in the PRP group. Significant improvement in PTA average in the PRP group. Graft uptake and percentage of perforation closure were higher in the PRP group and the control group.

The aim: The work was aimed to study the histological, morphometric and planimetric features of skin regeneration in mature rats with chronic hyperglycemia under the influence of platelet-rich plasma. Materials and methods: 60 mature white laboratory rats were used. The animals were divided into three groups (I – control with mechanical skin injuries; II – rats with chronic hyperglycemia and modeled mechanical skin injuries; III – animals with the chronic hyperglycemia and modeled mechanical skin injuries which were injected with the platelet-rich plasma). The samples were studied using light microscopy.Statistical data processing was performed using SPSS-17. Results: On the 21st day, the epithelialization of control mature rats wound was almost complete. The epithelium contained all layers without pathological changes. The new dermis has been reorganized into papillary and reticular layers. On the 21st day, the wound of rats with chronic hyperglycemia was not completely covered with the epidermis. The connective tissue of the dermis was disorganized. On the 21st day, the wound epithelialization was also more complete in mature rats with chronic hyperglycemia received platelet-rich plasma compared to the rats with chronic hyperglycemia. The dermis contained a large number of blood vessels with normal, full-blooded lumens. Conclusions: The chronic hyperglycemia leads to disruption of epithelialization processes, angiogenesis, a delay in the reorganization of dermis connective tissue, and vascular remodeling. The injections of autologous platelet-rich plasma promote faster angiogenesis, reduce inflammation, and accelerate wound epithelialization.

TITLE Efficacy of autologous platelet rich plasma over conventional mechanical fixation methods in split thickness skin grafting . AIMS AND OBJECTIVES to determine the efficacy of autologous platelet rich plasma over conventional mechanical fixation methods in split thickness skin grafting. METHODS  This a prospective randomized controlled study, conducted in the Department of surgery, SAIMS Medical College and P.G Institute, Indore for a period of two years from September 2016 to September 2018. A total of 20 patients were included in the study, and divided into two groups of 10 each randomly. The study was approved by the local ethical committee of our hospital. An informed written consent was obtained from all patients.  Total of 20 patients were studied; 10 cases were randomly chosen for study with autologous platelet rich plasma and 10 cases received conventional methods like staples/sutures used to anchor the skin grafts in a control group. RESULTS Autologous PRP showed faster and better healing rates. With PRP study group instant graft adherence was seen in all cases. Hematoma, graft edema, discharge from graft site, frequency of dressings and duration of stay in hospital were significantly less in the PRP. There were no adverse effects or reactions seen with the use of autologous PRP among the study group. CONCLUSION  The combination of PRP with Split Thickness Skin Graft (STSG) significantly improved clinical outcomes and shortened the wound healing time. Therefore, this treatment combination could provide a way to heal skin after skin graft reconstruction with minimal recovery time. It is found to be highly beneficial in many aspects both to the patient and surgeon based on our results.

Objectives assessment of structural changes in the calcaneal tendon tissue in experimental tendinopathy under autologous platelet-rich plasma. Material and methods. Twenty mature Wistar rats, selected for the study, were divided into 5 groups. Rats of all groups received intra- and peritendinous injections of 0.5 ml of 10% sterile talc suspension to provide the experimental modeling of tendinopathy of the calcaneal tendon. Then the tendinopathy area was treated by injections of autologous platelet-rich plasma (PRP), a hyaluronic acid preparation "Rusvisk" (Rusvisk, Russia) and their sequential combination. The results were evaluated after 10 weeks in the autopsy preparations using a light microscopy method and morphometry. Results. The histological signs characteristic of tendinopathy were revealed, such as the disorganization of collagen structures, mucoid and lipoid degeneration, neovascularization, lymphoid and histiocytic infiltration. The injection of PRP, hyaluronic acid, or their sequential combination in the area of simulated tendinopathy led to changes in the histological presentation of the tissue. As a result, the collagen matrix had less signs of disorganization and less pronounced degenerative changes, as well as manifestations of the inflammatory process in the peritenon and the soft tissues surrounding the tendon, in comparison with the histological profile, which was observed in micropreparations in animals with tendinopathy who had no treatment. Conclusion. The introduction of PRP into the area of the calcaneal tendon has reduced the manifestations of the inflammatory process, disorganization of the collagen matrix, promoted the enhancement of collagen synthesis by cells and, ultimately, the processes of tissue remodeling.
