O interesse da fibrina rica em plaquetas na medicina dentária

Dissertação para obtenção do grau de Mestre no Instituto Universitário Egas MonizA evolução da medicina dentária ao longo dos anos levou ao desenvolvimento de novos protocolos de tratamento. Desenvolvida no início dos anos 2000 após as colas de fibrina e o plasma rico em plaquetas (PRP), a fibrina rica em plaquetas (PRF) é baseada no uso do sangue autólogo do paciente, para obter um concentrado de plaquetas ricas em fatores de crescimento biocompatível. As plaquetas são fragmentos sanguíneas essenciais para a coagulação, mas também desempenham um papel crucial na regeneração e cicatrização dos tecidos. O uso da tecnologia da fibrina rica em plaquetas demonstrou ao longo dos anos, a sua capacidade de ser utilizada em uma ampla variedade de procedimentos dentários, devido às suas propriedades regenerativas, baixo custo, risco reduzido de contaminação e redução dos efeitos pós-operatórios. É principalmente utilizado para acelerar a cicatrização e a regeneração óssea e tecidual, especialmente em casos de implantologia, periodontia, cirurgia oral, bem como em casos de endodontia e patologia oral. O objetivo deste trabalho é apresentar, em uma revisão narrativa, o interesse da fibrina rica em plaquetas nas diferentes especialidades da medicina dentária. Uma pesquisa bibliográfica foi realizada nas bases de dados PubMed, Scopus, Google Scholar, Cochrane, Science Direct e Web of Science. Foram consideradas publicações científicas publicadas entre 2000 e o primeiro semestre de 2023.The evolution of dentistry over the years has led to the development and implementation of new treatment protocols. Developed in the early 2000s, following fibrin glues and platelet-rich plasma (PRP), the technology of platelet-rich fibrin (PRF) is based on the use of the patient's autologous blood to obtain a platelet concentrate rich in biocompatible growth factors. Platelets are blood fragments essential for clotting but also play a crucial role in tissue regeneration and healing. The use of Platelet-Rich Fibrin (PRF) technology has demonstrated its ability over the years to be used in a wide variety of dental procedures due to its regenerative properties, low cost, reduced risk of contamination, and minimizing post-operative effects. It is primarily used to accelerate tissue healing and regeneration, especially in cases of implantology, periodontics, oral surgery, as well as in cases of endodontics and oral pathology. The purpose of this article is, in a narrative review, to present the interest of platelet-rich fibrin in various fields of dental medicine. A literature search was conducted in databases including PubMed, Scopus, Google Scholar, Cochrane, Science Direct, and Web of Science. Scientific publications published between 2000 and the first semester of 2023 were considered.L'évolution de la dentisterie au fil des années a conduit à l'élaboration et à la mise en oeuvre de nouveaux protocoles de traitement.

Multiparametric determination of genes and their point mutations for identification of beta-lactamases

More than half of all currently used antibiotics belong to the beta-lactam group, but their clinical effectiveness is severely limited by antibiotic resistance of microorganisms that are the causative agents of infectious diseases. Several mechanisms for the resistance of Enterobacteriaceae have been established, but the main one is the enzymatic hydrolysis of the antibiotic by specific enzymes called beta-lactamases. Beta-lactamases represent a large group of genetically and functionally different enzymes of which extended-spectrum beta-lactamases (ESBLs) pose the greatest threat. Due to the plasmid localization of the encoded genes, the distribution of these enzymes among the pathogens increases every year. Among ESBLs the most widespread and clinically relevant are class A ESBLs of TEM, SHV, and CTX-M types. TEM and SHV type ESBLs are derived from penicillinases TEM-1, TEM-2, and SHV-1 and are characterized by several single amino acid substitutions. The extended spectrum of substrate specificity for CTX-M beta-lactamases is also associated with the emergence of single mutations in the coding genes. The present review describes various molecular-biological methods used to identify determinants of antibiotic resistance. Particular attention is given to the method of hybridization analysis on microarrays, which allows simultaneous multiparametric determination of many genes and point mutations in them. A separate chapter deals with the use of hybridization analysis on microarrays for genotyping of the major clinically significant ESBLs. Specificity of mutation detection by means of hybridization analysis with different detection techniques is compared
