“…Mima et al reported that photodynamic therapy resulted in the reduction of CFU/mL of C. albicans , C. glabrata , C. tropicalis, C. dubliniensis, and C. krusei [ 40 ]. Moreover, inhibition of C. albicans biofilm formation by silver nanoparticles in the surgical sites was reported in the literature [ 41 ].…”

Background and Purpose: This study aimed to evaluate the effect of common photodynamic therapy and photodynamic therapy by the silver nanoparticle, methylene blue, and their combination on biofilm and plankton cells of standard oral Candida isolates using cell viability assay. Materials and Methods: In this in vitro study, biofilm and plankton cells of Candida species(i.e. C .albicans and C. parapsilosis) and plankton cells of Candida glabrata were treated with methylene blue, silver nanoparticle, and their combination once alone and then with the irradiation of total dose of 1.92 J/cm² for 60 sec. The minimum inhibitory concentration and antifungal activity of each approach were evaluated using the XTT assay. Results: After photodynamic therapy, methylene blue showed antifungal effect only on Candida albicans, while the antifungal effect of silver nanoparticles was increased on all Candida species. On the other hand, photodynamic therapy with the combination of methylene blue and silver nanoparticles did not have any effect on C. albicans. However, it reduced the minimum inhibitory concentration value of C. parapsilosis, and the most antifungal effect was observed on C. glabrata. Conclusion: Photodynamic therapy with photosensitizers can serve as a treatment modality in Candida infections of the oral cavity. Antifungal effect of photodynamic therapy was strain- and photosensitizer-dependent.

“…PRP groups were less inflamed than non-PRP equivalents. PRP and other platelet derivatives are proven to have microbiocidal properties, this may help in not calling inflammatory cells (16,17). Inflammation is likely to degrade the intact collagen and destroy the viable cells, consequently exacerbating the functional deficit and prolonging the recovery period.…”

Does PRP Improve the Tendon Gap Healing?

Background:The tendon repairs slowly. Platelets' alpha granules contain polypeptide growth factors that stimulate proliferation of normal connective tissue cells. The acute phase of inflammation is necessary for healing progress and fibroplasia. Platelet growth factors initiate and accelerate the inflammatory response by the host. Objectives: This study aimed to investigate if platelet-rich plasma (PRP) helps tendon gap healing. Methods: Aseptic surgery was performed on 24 mature guinea pigs in four groups to excise a 7-mm piece of the deep digital flexor (DDF) tendon of the right hind leg. In groups 1 and 2, the two ends of the severed tendon were sutured in the fascia conduit; group 2 received PRP injection into the conduit. In groups 3 and 4, the two ends of the severed tendon were sutured in a silicone tube conduit, and group 4 received PRP injection. After 42 days, the animals were euthanized and tendon samples were collected for further study. Results: The histopathological and stereological data showed that inflammation was far less in PRP-treated groups as they showed more fibroblastic proliferation. The synergistic effects of silicone tube and PRP injection showed the least inflammatory response. The diameter of collagen bundles and their volume were higher in the groups which received PRP in the silicone conduit. Conclusions: The present study found that PRP improved healing of tendon injury and silicone conduit served as good surgical technique with synergistic effect beside PRP.

“…One of the most common oral infections, especially amongst HIV-positive individuals and the elderly population, is oral candidiasis [ 5 , 20 , 24 , 31 , 32 , 33 ]. Also known as “thrush” or “candidosis”, this fungal infection is characterized by Candida spp.…”

“…Streptococcus mitis is another type of bacteria in the human mouth that is commonly found in the throat and nasopharynx as a colonized organism. It can cause infection in immunocompromised patients with moderate or severe clinical diseases [ 33 ]. The risk for oral infections by opportunistic bacteria is also increased in individuals taking chemotherapeutic drugs, as this may alter the receptor interaction between pathogens and epithelial cells and increase bacterial adhesion, while reducing the salivary secretion rate and oral pH.…”

Oral health is an essential element in maintaining general well-being. By preserving the complex equilibrium within the oral microbial community, commensal microorganisms can protect against extrinsic pathogenic threats. However, when an imbalance occurs, the organism is susceptible to a broad range of infections. Synthetic drugs can be administered to help the body fight against the fungal, bacterial, or viral burden. Nonetheless, they may produce undesirable consequences such as toxicity, adverse effects, and drug resistance. In this respect, research has focused on finding safer and more efficient alternatives. Particularly, increasing attention has been drawn towards developing novel formulations based on natural compounds. This paper reviews the plant-based, algae-based, and beehive products investigated for their antimicrobial properties, aiming to thoroughly present the state of the art on oral infection prevention in the ear, nose, and throat (ENT) field.
