RESUMO
Introduction: The human oral cavity comprises various niches such as teeth, gingiva, tongue, soft and hard palate, and various dental prostheses, all inhabited by different bacterial species. Although more than 600 taxa belong to the oral cavity, identifying Staphylococcus arlettae , an incompletely understood bacterium, has been rare. Methods: Three patients who underwent periodontal flap surgeries were reported with the incidental finding of S. arlettae associated with the intra-oral sutures placed. Environmental sampling was performed, to establish the exact source of this bacterium. Results: Staphylococcus arlettae was isolated in three patients' intra-oral sutures. All environmental samples were negative for the presence of the bacterium. Conclusion: . To this date, no studies have identified such an occurrence of Staphylococcus arlettae with intra-oral sutures. Its identification in association with foreign materials, such as sutures, can be considered a potential for surgical site infections and requires further investigation.
RESUMO
Antibiotic resistance in Pseudomonas aeruginosa remains one of the most challenging phenomena of everyday medical science. The universal spread of high-risk clones of multidrug-resistant/extensively drug-resistant (MDR/XDR) clinical P. aeruginosa has become a public health threat. The P. aeruginosa bacteria exhibits remarkable genome plasticity that utilizes highly acquired and intrinsic resistance mechanisms to counter most antibiotic challenges. In addition, the adaptive antibiotic resistance of P. aeruginosa, including biofilm-mediated resistance and the formation of multidrug-tolerant persisted cells, are accountable for recalcitrance and relapse of infections. We highlighted the AMR mechanism considering the most common pathogen P. aeruginosa, its clinical impact, epidemiology, and save our souls (SOS)-mediated resistance. We further discussed the current therapeutic options against MDR/XDR P. aeruginosa infections, and described those treatment options in clinical practice. Finally, other therapeutic strategies, such as bacteriophage-based therapy and antimicrobial peptides, were described with clinical relevance.
RESUMO
Bone resorption following tooth loss is an obvious, continuous, and unpredictable process, which poses one of the greatest challenges in implant placement. The posterior regions of the jaws show more resorption compared to the anterior regions, with the mandible being affected more. Augmentation of the narrow alveolar ridge has been done using various techniques. The alveolar ridge split technique (ARST) is frequently used for the horizontal augmentation of the narrow ridge. In this case report, a 47-year-old female patient who had partial edentulism on the lower left jaw region associated with a narrow alveolar ridge was treated using the ridge split technique. A piezosurgical unit was used for splitting the ridge, followed by simultaneous implant placement. This alveolar ridge split technique is considered to be more predictable, reliable, and successful as compared to other techniques such as autogenous onlay bone graft and guided bone regeneration.
