Introduction: Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves, usually of the lower limbs. Considering that PRP is a source of growth factors, and consequently has mitogenic, angiogenic, and chemotactic properties, it represents an adjunctive treatment for recalcitrant wounds. Moreover, PRP provides the wound with adhesive proteins, such as fibrinogen, which are important in wound healing. PRP contain more amount of platelets, cytokines and growth factors which are dispersed in a very small amount of plasma which can be prepared from a sample of centrifuged autologous blood. Application of PRP has been reported to be effective in both acute as well as chronic non healing venous ulcers. Aim and Objective: To evaluate the efficacy of autologous platelet rich plasma in the management of chronic venous ulcer. Material and Method: A Prospective study conducted on 100 patients of chronic venous ulcers admitted in Sir T. Hospital Bhavnagar from June 2018 to June 2019 after fulfilled our inclusion and exclusion criteria. PRP then injected intalesionally inside and around the periphery of the wound/ulcer. This process was done once/week for 12 weeks. At every week, the area and volume of ulcer was calculated and photographs were taken. Result: All the patients showed healing of the ulcer with reduction in size of ulcer more than 90% was observed in 72 patients, followed by 80–90% reduction in wound size in 18 patients after the 12 weeks follow-up. Overall, significant reduction in size of ulcer was observed in all the treated patients. Conclusion: Autologous platelet rich plasma (PRP) as an autologous method, it is biocompatible, simple, safe, affordable and less expensive procedure in the treatment of chronic venous ulcers. PRP is found to be useful in improving and enhancing the healing process in chronic venous leg ulcers without any side effect. Keywords:  Venous ulcer, Platelet rich plasma

<p class="abstract"><strong>Background:</strong> Tympanoplasty involves grafting the perforation of the tympanic membrane with materials such as temporalis fascia, cartilage perichondrium, periosteum, vein, fat etc. Both temporalis fascia and cartilage perichondrium are easy to harvest with minimum donor site complications and both have been used extensively in tympanoplasty. Platelet rich plasma aids as an adhesive and supplements healing by providing growth factors. Till date there is scarcity of literature comparing the healing outcome of both cartilage perichondrium and temporalis fascia supplemented with platelet rich plasma. Hence, in this study we are comparing cartilage perichondrium supplemented with platelet rich plasma and temporalis fascia supplemented with platelet rich plasma.  </p><p class="abstract"><strong>Methods:</strong> An observational study involving 60 patients was done. Patients with chronic otitis media were evaluated by otoendoscopy to assess the ear and were categorised into 2 groups which received temporalis fascia and cartilage perichondrium respectively. All cases were supplemented with platelet rich plasma. Post-operative assessment was done by otoendoscopy.   </p><p class="abstract"><strong>Results:</strong> Total 21 patients received temporalis fascia and 39 patients received cartilage perichondrium. At the end of 6 weeks the graft site appeared unhealthy in 6.66% cases who received temporalis fascia and 1.66% in those who received cartilage perichondrium.  </p><p class="abstract"><strong>Conclusions:</strong> We found that cartilage perichondrium supplemented with platelet rich plasma had a better uptake after 6 weeks due to its superior mechanical stability. The results are more rewarding than the use of temporalis fascia with platelet rich plasma.</p>

Osteoarthritis is the most common form of arthritis and a leading cause of chronic disability, to a great extent in knee and/or hip joints. Osteoarthritis, commonly known as wear and tear in which a protective cartilage on the end of the bones wears down over time. osteoarthritis of the knees is one of five leading causes for disability among non-institutionalized adults. Osteoarthritis is the fourth leading cause of 'years lived with disability' (YLD), accounting for 3.0% of totals global YLD's. As per WHO by 2030. The most common symptoms of knee osteoarthritis are pain and physical limitations that have a significant effect on the individual's quality of life and her or his social and economic activities. Osteoarthritis diseases are a result of both mechanical and biological events that destabilize the normal biological coupling of degradation and synthesis of articular cartilage, chondrocytes, extracellular matrix, subchondral bone and subsequently synovial fluid. Current research efforts are focused on the identification of key biochemical pathways that can be targeted therapeutically through biological intervention for cartilage repair. Autologous platelet-rich plasma (PRP), which contains a pool of growth factors, appears to offer an easy solution for delivering multiple growth factors needed for tissue repair. PRP therapy provides delivery of a highly concentrated of growth factors to accelerate healing. The present study has been undertaken in Gandhi Medical College, Hospital, Hyderabad, Telangana, India to study the role of PRP in the osteoarthritis of knee joint. In this study PRP from the patient’s own blood i.e. autologous PRP has been immediately infiltrated into their knee joints with osteoarthritis and the results of injection of PRP have been observed and assess the functional outcome. It is a prospective longitudinal study on 100 patients with 161 primary osteoarthritic knee joints of Kellgren Lawrence radiological grade I-61 and II - 100. Patients were assessed with WOMAC (Western Ontario McMaster Universities Arthritis Index) scoring pre injection of PRP and post injection period of 1 month and 6 months. A reduction in WOMAC score is suggestive of improvement in the patient’s condition. In this study, the pain scores of the patients have decreased on the day of infiltration to one month and six months. Their mean scores have decreased from the day of infiltration to one month and six months. All the patients have started showing improvement at around two weeks and over all, the pain intensity has decreased in severity. It can be concluded that the efficacy of the PRP treatment from zero day to sixth month is statistically significant.

Aim: The photoreceptors in retinitis pigmentosa (RP) remain in dormant status for a while with a decrease in the growth factors in their microenvironment before apoptosis. Growth factors reduce retinal degeneration and apoptosis in animal models. Materials & methods: The data of 188 eyes of 94 patients who were injected with autologous platelet-rich plasma (PRP) into the subtenon space three-times every 2 weeks were evaluated retrospectively. Results: Statistically significant improvements in visual acuity, visual field and fixation stability were detected after treatment. When the treatment response of the patients' better-seeing eye compared with the response of the other eye, there was no statistically significant difference. Conclusion: The PRP treatment has a favorable effect on visual functions in patients with RP. This approach is promising as it is safe and easy.

The current experimental study was conducted in sheep, which present bone anisotropy and a predisposition to periodontal disease, with alveolar bone resorption, similar to that found in humans. In this study, alveolar bone augmentation was performed using a lyophilized bovine bone xenograft enriched with type 1 atelocollagen, which was combined with autologous platelet-rich plasma (PRP) and advanced platelet-rich fibrin (A-PRF) as a membrane. The results were radiologically and histologically evaluated at six weeks postoperatively. At that time, the transformation of the composite biomaterial was clearly visible, suggesting that the regeneration process started from the periphery of the augmentation mass, which was progressively transformed from a granular eosinophilic material into an undifferentiated hypercellular one, then into fibroblastic, cartilaginous tissue, and finally into new bone and desmodontal-like tissue. This process was most probably induced by all the compounds used, the growth factors found in autologous blood derivatives, including bone morphogenetic proteins (BMPs), as well as type 1 atelocollagen from the graft composition, especially in combination. The composite biomaterial at six weeks postoperatively provided excellent results regarding alveolar bone regeneration, and without any risk, as opposed to that found in overdose of recombinant growth factors.
