Abstract
PURPOSE There are few options for treatment of dysphonia secondary to vocal pathology related to lamina propria scar, atrophy, sulcus, or inflammatory disorders. Platelet rich plasma (PRP) may provide anti-inflammatory and regenerative properties seen with other tissue engineering therapies without the risks associated with these treatments. We evaluated vocal fold (VF) injection of PRP for feasibility, phonatory effects, patient satisfaction and durability. METHODS Patients with dysphonia secondary to vocal fold scar, atrophy, sulcus and inflammatory lesions were included. PRP injections were administered in office, to bilateral vocal folds. Patients were followed up at 1 week, 1 month, 3 months and 6 months to assess outcomes (GRBAS scale, maximum phonation time, vocal fatigue index (VFI), voice handicap index (VHI-10) and stroboscopy). RESULTS 75 intracordal PRP injections were administered to 48 patients. All injections were completed, and no adverse reactions were experienced. Improvements in VHI-10 scores at 1,3,6 months were seen (mean VHI 21.73 at baseline, 15.62 at six months, p < 0.001). 72.3% rated improvement at 7 or above on Likert scale. 95.7% of patients would consider a future PRP injection. Secondary outcomes VFI, MPT, and GRBAS also demonstrated significant improvements over time. Patients receiving a single PRP injection (n = 26) still demonstrated significant VHI-10 improvements at 1,3 and 6 months. CONCLUSIONS VF office PRP injections are feasible and safe and can provide phonatory benefit and reduce vocal effort in benign VF disorders. A single PRP injection is sufficient to provide sustained benefit in some cases. LEVEL OF EVIDENCE Level III: prospective cohort study.

[PMID: 34384663 DOI: 10.1016/j.jvoice.2021.07.007] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 07/12/2021] [Indexed: 11/15/2022]
Abstract
BACKGROUND Platelet rich plasma (PRP) and platelet poor plasma (PPP) are regenerative therapies that offer the potential for improving care for disorders of the larynx. The laryngeal applications of these substances have been examined in both animals and humans. The goal of this systematic review is to examine the various applications of PRP and PPP in laryngology, assess the protocols for preparation and application of these substances and evaluate the outcomes and complications in both humans and animals. METHODS A search of PUBMED was conducted in April 2021 using combinations of keywords of "platelet rich plasma" and "platelet poor plasma" with keywords such as "larynx," "vocal folds," "laryngology," and others. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRIMSA) guidelines were followed. Articles were reviewed by two independent coauthors and included based on selection criteria pertinent to the goals of this study. The risk of bias in the included studies was assessed by two independent co-authors using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Randomized Controlled Trials and JBI Critical Appraisal Checklist for Quasi-Experimental Studies. Data regarding the pathologies treated using PRP and PPP, PRP, and PPP preparation protocols, application protocols, human voice outcomes, histopathological animal outcomes, and complications were extracted from each of the studies and presented in tables. RESULTS Seven studies were included based on the selection criteria. PRP or PPP were used for vocal fold scar, sulcus, atrophy and palsy; acute vocal fold injury; glottic insufficiency, and graft healing. PRP or PPP were derived from autologous blood in a one- or two-step centrifugation process and administered via injection, soaking of cartilage grafts or topical application. Mean and median voice handicap index-10 (VHI-10) and voice handicap index (VHI) scores decreased following PRP or PPP injections in two human studies and one human study showed a similar VHI-10 score before and after PRP treatment. Videostroboscopy showed the absence of injection site reactions and at least temporary improvement in glottic gap or vibratory function following treatment in some patients. Other objective measures of voice outcomes in human studies showed improved phonatory function in the one-to-four-month period following PRP or PPP injections, with some patients experiencing a subjective decrease or return to baseline in phonatory function following the initial improvement period. Animal studies found elevated levels of growth factors, organized collagen deposition, decreased granulation tissue, increased vascularization, and increased cartilage proliferation in PRP treated laryngeal tissue. DISCUSSION PRP and PPP might have the potential to be safely used in the larynx and at least temporarily influence wound healing and vocal function. Further study using comparable outcome measurement tools is required to assess their role and efficacy in treating acute vocal fold injury, chronic vocal fold pathologies, graft healing, and other laryngeal applications.

Abstract
The preparation of autologous platelet and extracellular vesicle-rich plasma (PVRP) has been explored in many medical fields with the aim to benefit from its healing potential. In parallel, efforts are being invested to understand the function and dynamics of PVRP that is complex in its composition and interactions. Some clinical evidence reveals beneficial effects of PVRP, while some report that there were no effects. To optimize the preparation methods, functions and mechanisms of PVRP, its constituents should be better understood. With the intention to promote further studies of autologous therapeutic PVRP, we performed a review on some topics regarding PVRP composition, harvesting, assessment and preservation, and also on clinical experience following PVRP application in humans and animals. Besides the acknowledged actions of platelets, leukocytes and different molecules, we focus on extracellular vesicles that were found abundant in PVRP.

Abstract
Background Atrophic acne scarring is an unpleasant and often permanent complication and a therapeutic challenge for dermatologists. Platelet-poor plasma (PPP) gel injections are derived from the patient's own blood and used as a "biofiller" for skin rejuvenation. Objectives The objective was to study the efficacy and safety profile of PPP gel in atrophic acne scars. Materials and Methods Thirty patients with atrophic acne scars were included in the study. Topical anesthesia was applied on the area of interest 45 min prior to the procedure. 20 mL of blood was collected in eight sodium citrate bulbs and centrifuged to get PPP that is coagulated with heat to form gel. This gel (biofiller) was injected in the scarred areas monthly for 6 months. Patients were evaluated using Goodman and Baron Scar (GBS) scale (quantitative and qualitative), Physician Global Assessment, and Visual Analogue Scale (VAS) at each visit. The final visit was after 3 months of the last procedure. Results The mean value of GBS at the first visit was 28, which reduced to 8.2 at the final visit. The analysis of variance test was applied to the quantitative scale from the baseline visit to the final visit. The F value was 462.55 with a P value < 0.0001. The paired t-test was applied for the GBS quantitative scale, which showed a value of 22.86 with a P value of <0.001. Transient local side effects were noted. Conclusion Biofiller is efficacious in improving atrophic acne scars. It is a simple, minimally invasive, cost-effective procedure with no risk of immunogenic reaction.

Abstract
Platelet-rich plasma (PRP) is being used as a treatment modality for skin rejuvenation since the last decade. There has been a lot of ambiguity regarding the ideal protocol to be followed and the specific indications where its use should be promoted. The use of PRP as monotherapy for skin rejuvenation, acne scars, periorbital rejuvenation, lipofilling and in combination with fractional CO2 and other resurfacing modalities is increasing rapidly. In this article, we have reviewed the current scientific evidence available and the IADVL national task force for PRP has come up with standard recommendations for use of PRP in esthetics along with the grade of evidence and strength of recommendation for each indication. The aim of this review is to provide a standard protocol for use of PRP in esthetics, for clinicians and academicians, leading to excellent results with this promising treatment modality.

Abstract
Infraorbital dark circles and tear trough deformity are considered common aesthetic problems. Numerous therapeutic modalities have been suggested with variable outcomes. The aim of this study was to compare the efficacy of platelet-poor plasma (PPP) gel vs platelet-rich plasma (PRP) in infraorbital rejuvenation. A total of 68 females presented with dark circles and/or tear trough deformity were recruited and treated by PPP gel injection in the right infraorbital region (Group A) and PRP injection in the left infraorbital region (Group B). They received three treatment sessions at 2-week interval, and followed up monthly for 3 months. They were evaluated clinically and dermoscopically before treatment and at the end of follow-up period. Both groups showed significant clinical improvements proved by significant reduction of degree of hyperpigmentation and tear trough rating scale. Obviously, more significant clinical and dermoscopic improvements were observed in Group A than Group B. Therefore, it could be concluded that both PPP gel and PRP were clinically effective procedures for aesthetic improvement of infraorbital region. Moreover, PPP gel seems to be significantly more effective than PRP as a therapeutic modality.

Abstract
There is a continuous need for modifications of epidermal cell grafting techniques treating stable vitiligo to make it easier, more economic, and with better outcome. To evaluate the efficacy and safety of noncultured, nontrypsinized epidermal cell graft homogenized with plasma gel, followed by narrow band-ultraviolet B (NB-UVB) in treatment of stable vitiligo, about 40 patients with stable vitiligo underwent harvesting of epidermal cells from the donor site by dermabrasion then the harvested cells were prepared, homogenized with autologous plasma gel, and applied to the abraded recipient, followed by 16 NB-UVB sessions after complete healing. Patches within the same anatomical site received only NB-UVB as controls. The percentage of improvement ranged from 23.33% to 100% with more than 75% uniform, homogenous repigmentation in 65% of patients. Donor site healed completely with normal skin. Noncultured, nontrypsinized epidermal cell grafting technique homogenized with plasma gel followed by NB-UVB sessions gave positive responses and was well tolerated in different body sites in stable resistant vitiligo.

Abstract
BACKGROUND Postacne scarring is an unfortunate and frequent complication of acne, with varied morphological forms and associated significant psychological distress to patients. AIM OF THE WORK To evaluate the efficacy and safety of plasma gel injection alone and in combination with microneedling in treatment of atrophic postacne scars. PATIENTS AND METHODS Sixty patients with atrophic postacne scars were enrolled in this single blinded randomized controlled study. The patients were divided into three groups with 20 patients being treated with intradermal injection of plasma gel, 20 patients treated with dermaroller, and 20 patients subjected to combined plasma gel and dermaroller. Patients received four sessions at monthly intervals and were evaluated by clinical, histopathological, and immunohistochemical analysis. RESULTS There was statistically significant improvement in postacne scars after treatment in all studied groups with variable degrees; the combined technique showed the best clinical improvement in postacne scars. There was an increase in newly formed collagen and elastic fibers with more organized and condensed bundles after the end of treatment. CONCLUSION Plasma gel showed a remarkable improvement for most patients after one session, providing a quick and easy solution for acne scars. The combination of dermaroller and plasma gel potentiated its effect with more improvement in scars.

Abstract
BACKGROUND The popularity of dermal fillers has grown rapidly in the last few years for facial rejuvenation. Plasma gel is an autologous gelatinous material that is prepared from the patient's own platelet poor plasma. OBJECTIVE To evaluate the clinical efficacy and safety of plasma gel injection as a dermal filler for facial rejuvenation. PATIENTS AND METHODS The current study was carried out on 52 females presented with facial aging divided into two groups: Group A included 34 females with facial wrinkles, and Group B included 18 females with tear trough deformity. After taking written informed consent, they received two sessions of plasma gel injections at 2-week interval and followed up monthly for 3 months. They were assessed clinically before treatment sessions and at the end of follow-up period. RESULTS Both studied groups showed immediate significant clinical improvement after plasma gel injection that maintained till the end of follow-up period. This finding was confirmed by significant reduction in the mean values of Wrinkle Severity Rating Scale (WSRS) in Group A and Tear Trough Rating Scale (TTRS) in group B, and significant improvement of skin homogeneity and texture in both groups. In general, the reported side effects were minimal and transient. CONCLUSION Autologous platelet poor plasma gel injection seems to be a cost-effective, safe, well-tolerated, and minimally invasive technique producing significant aesthetic correction of facial wrinkles and tear trough deformity.

Abstract
Hypoparathyroidism is a deficiency of the parathyroid hormone (PTH) in the body. We previously reported the possibility of treating it using tonsil-derived mesenchymal stem cells (TMSCs) differentiated into PTH-releasing cells. The purpose of this study was to evaluate the feasibility of using autologous plasma gel as scaffold material in treatment of hypoparathyroidism with TMSC. We obtained plasma by venous sampling of autologous blood and centrifuged and fabricated the plasma gel using a sinusoidal pattern heating machine. After we created the hypoparathyroidism animal model, we administered undifferentiated TMSCs and TMSCs differentiated into parathyroid cells at each rat dorsum by intramuscular injection with and without the plasma gel. In the plasma gel groups, intact PTH was detected from on day 21 after TMSC injection; we did not detect intact PTH in the groups that were only transplanted with TMSCs during the entire experimental period. Serum calcium was higher and phosphorous was lower in the TMSC with plasma gel groups than in the groups with TMSCs alone. We detected PTH and chromogranin A in the TMSC-plasma gel-transplanted areas on immunohistochemistry and immunofluorescence stain. Plasma gel can be considered as a cell-delivery scaffold for treating hypoparathyroidism with tonsil-derived mesenchymal stem cells.

Abstract
Injection medialization laryngoplasty is a procedure that has many advantages in treating vocal fold paralysis; however, undesired complications can occur. We experienced a case of a pulmonary embolism, suspected in a patient who had undergone an injection laryngoplasty with calcium hydroxylapatite (CaHA). The patient suffered dyspnea after undergoing the injection laryngoplasty. Chest embolism computed tomography (CT) scan revealed a new lesion of enhancing materials at the pulmonary vasculature in the right upper lobe. The CaHA embolism was suspected, and the patient was treated with warfarin for 12 months. The patient's symptom of dyspnea nearly disappeared and a follow up chest embolism CT scan revealed no signs of the previous lesion. Thus, we would like to report this rare case along with a review of the literature.

Yang L, Ma J, Gan S, Chu S, Maldonado M, Zhou J, Ma L, Tang S. Platelet poor plasma gel combined with amnion improves the therapeutic effects of human umbilical cord‑derived mesenchymal stem cells on wound healing in rats. Mol Med Rep 2017; 16:3494-3502. [PMID: 28714022 DOI: 10.3892/mmr.2017.6961] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Accepted: 05/08/2017] [Indexed: 02/05/2023] Open
Abstract
The aim of the present study was to investigate the efficacy of human umbilical cord‑derived mesenchymal stem cell (HUMSCs) embedded in platelet poor plasma (PPP) gel combined with amnion (PPPA) in improving wound healing on Sprague‑Dawley (SD) rats. HUMSCs were cultured and labeled with chloromethylbenzamido‑1,1'‑dioctadecyl‑3,3,3'3'‑tetramethylindocarbocyanine perchlorate (CM‑DiI) on their third passage. The expression levels of growth factors of HUMSCs in PPPA were assessed by ELISA. Full‑thickness excisional skin wounds were induced in 36 male SD rats, which were treated with PPPA grafted with HUMSCs (PPPAC), PPPA, or HUMSC or PBS injection. The degree of healing and the distribution of labeled HUMSCs in the wound were evaluated by hematoxylin and eosin (H&E) staining and immunofluorescence. On day 14 post‑surgery, wound healing in PPPAC‑treated rats was significantly higher than the PPPA group, compared with rats treated with HUMSCs alone and control rats (P<0.05 and P<0.01, respectively). H&E staining showed that morphology and thickness of the epidermis in the PPPAC group was similar to that of healthy skin. ELISA revealed that levels of growth factors of HUMSCs in PPPAC were higher than in monolayer cells. In conclusion, PPPA can modify growth factor expression levels of HUMSCs and improve the efficiency of HUMSCs in the healing of full thickness wounds in rats.
