Abstract
OBJECTIVE To evaluate the value of intrauterine platelet-rich concentrates among patients with intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis. METHODS Four different databases (PubMed, Cochrane Library, Scopus, and ISI web of science) were searched for the available studies from inception to November 2021. We selected randomized clinical trials (RCTs) that compared platelet-rich concentrates in the intervention group versus no injection of platelet-rich concentrates in the control group among women with intrauterine adhesions after operative hysteroscopy. Revman software was utilized for performing our meta-analysis. Our primary outcomes were the adhesion score and incidence of recurrence of severe intrauterine adhesions postoperatively. Our secondary outcomes were the clinical pregnancy rate, menstrual flow duration in days, and menstrual flow amount (number of pads). RESULTS Five RCTs met our inclusion criteria with a total number of 329 patients. We found that platelet-rich concentrates were linked to a significant reduction in the postoperative adhesion score (MD = -1.00, 95% CI [-1.68, -0.32], p = 0.004). Moreover, there was a significant reduction in the incidence of severe IUAs recurrence among the platelet-rich concentrates group (7.6%) compared to the control group (23.4%) after hysteroscopy (p = 0.001). The clinical pregnancy rate was significantly increased among the platelet-rich concentrates group (37.1%) in comparison with the control group (20.7%) after hysteroscopic adhesiolysis (p = 0.008). There were significant improvements in the menstrual flow duration and amount among the platelet-rich concentrates group (p < 0.001). CONCLUSIONS Intrauterine placement of platelet-rich concentrates is an effective method for the treatment of intrauterine adhesions after hysteroscopy.

Abstract
BACKGROUND Post-spinal back pain is suggested to occur as a result of a localized inflammatory response that is often associated with some degree of muscle spasm. We aimed to evaluate the effect of platelet-rich plasma (PRP) in reducing the incidence of post-spinal back pain. METHODS One hundred patients were randomly enrolled and scheduled for elective gynecological surgery under spinal anesthesia. After the subarachnoid block, group A (placebo) received 2 mL of sodium chloride 0.9% injected into the track of spinal needle during its withdrawal (2 mm after outward withdrawal in muscles and subcutaneous tissues). While patients in group B (PRP); received 2 ml of PRP injected into the track of the spinal needle during its withdrawal. The primary outcome was the number of patients who developed post-spinal low back pain within the first week following the subarachnoid block. Secondary outcomes included the time of the first analgesic request and total meperidine consumption during the first 24 h postoperatively. RESULTS Fifteen patients in the PRP group developed low back pain during the first week following subarachnoid block compared to 26 patients in the placebo group (p = 0.037). There was a significant decrease in the mean meperidine consumption during first 24 h postoperatively in PRP group (174 ± 14 mg) compared to placebo group (210 ± 22 mg) (p < 0.0001). Also, the first analgesic request was significantly delayed in PRP group (243 ± 21 min.) compared to placebo group (185 ± 31 min.) (p < 0.0001). CONCLUSION This study demonstrated the positive effects of platelet-rich plasma on the prevention of post-spinal backache.

Abstract
OBJECTIVE The aim of the present study was to evaluate the effect of autologous platelet-rich plasma (PRP) on wound healing and pain perception after cesarean section in high-risk patients. DESIGN This was a prospective randomized controlled trial. Participants/Materials, Settings, and Methods: This was a randomized controlled trial of 200 patients who came to the outpatient clinic of Menoufia University Hospital for elective cesarean surgery. The women were randomly assigned to 2 equal groups. The intervention group received PRP subcutaneous injection in the wound after surgery; however, the control group received the usual care. Outcome variables included the redness, edema, ecchymosis, discharge, approximation (REEDA) scale, Vancouver scar scale (VSS), and in addition to the visual analog scale (VAS). RESULTS From April 2018 to July 2020, the PRP group showed a greater reduction in the REEDA score compared to the control group on day 1, day 7, and this was continued till 6 months (1.51 ± 0.90 vs. 2.49 ± 1.12, p < 0.001). Compared with the control group, the PRP group had a significantly greater reduction in the VSS and VAS scores beginning on the seventh day (3.71 ± 0.99 vs. 4.67 ± 1.25, p < 0.001) and (5.06 ± 1.10 vs. 6.02 ± 1.15, p < 0.001), respectively, and continued till 6 months. LIMITATIONS Pain was not measured by the use of analgesics, and we did not investigate the effects of varying platelet concentrations, centrifuge duration, or speed. CONCLUSIONS PRP has positive effects on wound healing and pain reduction in high-risk patients undergoing cesarean section in low-resource settings.

Abstract
BACKGROUND Platelet-rich plasma (PRP) is a human plasma product enriched by platelets, growth factors, and fibrinogen with high hemostatic and healing properties. OBJECTIVES The aim of this study was to evaluate the effect of autologous PRP on wound healing in high-risk women undergoing cesarean sections. PATIENTS AND METHODS In this balanced, randomized, and controlled trial, 140 patients were admitted to Arash women's hospital, Tehran, Iran from May of 2013 to November of 2014 for elective cesarean surgery. The patients were randomly assigned into two groups. The intervention group received PRP after surgery, whereas the control group received the usual care. All patients were evaluated at baseline, five days, and eight weeks after the cesarean section. The primary endpoint used the REEDA scale for assessing the changes in wound healing. The secondary outcome measures used were the Vancouver scar scale (VSS) and the visual analog scale (VAS). All scale scores were analyzed using a repeated measures test for variance. RESULTS At the end of study, the PRP group showed a greater reduction in the edema ecchymosed discharge approximation (REEDA) score compared to the control group (85.5% reduction in the PRP group; 72% in the control group) (P < 0.001). Compared with the control group, the PRP group had a significantly greater reduction in the VAN score, beginning on the fifth day after the cesarean section (-0.7, 38% reduction in PRP group; -0.8, 33% in control group) (P < 0.001), and this trend was stable at the end of the eighth week (-0.6, 54% reduction in PRP group; -0.3, 18% in control group). Furthermore, patients treated with PRP experienced a 93% reduction in the VAS score at the end of follow-up, but the control group only observed a 79% reduction (P < 0.001). CONCLUSIONS It seems that applying PRP is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors.
