Background: Two-stage septic revision is the prevailing method for addressing late periprosthetic infections. Using at least dual-antibiotic-impregnated bone cement leads to synergistic effects with a more efficient elution of individual antibiotics. Recent data on the success rates of multiantibiotic cement spacers in two-stage revisions are rare.
Methods: We conducted a retrospective follow-up single-center study involving 250 patients with late periprosthetic hip infections and 95 patients with prosthetic knee infections who underwent septic two-stage prosthesis revision surgery between 2017 and 2021. In accordance with the antibiotic susceptibility profile of the microorganisms, a specific mixture of antibiotics within the cement spacer was used, complemented by systemic antibiotic treatment. All patients underwent preoperative assessments and subsequent evaluations at 3, 6, 9, 12, 18, and 24 months post operation and at the most recent follow-up.
Results: During the observation period, the survival rate after two-step septic revision was 90.7%. Although survival rates tended to be slightly lower for difficult-to-treat (DTT) microorganism, there was no difference between the pathogen groups (easy-to-treat (ETT) pathogens, methicillin-resistant staphylococci (MRS), and difficult-to-treat (DTT) pathogens). Furthermore, there were no differences between monomicrobial and polymicrobial infections. No difference in the survival rate was observed between patients with dual-antibiotic-loaded bone cement without an additional admixture (Copal G+C and Copal G+V) and patients with an additional admixture of antibiotics to proprietary cement.
Conclusion: Employing multiple antibiotics within spacer cement, tailored to pathogen susceptibility, appears to provide reproducibly favorable success rates, even in instances of infections with DTT pathogens and polymicrobial infections.

Bone cement is commonly utilized to secure prosthetic joints in the body because of its robust fixation, stability, biocompatibility, and immediate load-bearing capability. However, issues such as loosening, leakage, and insufficient bioactivity can lead to its failure. Therefore, improving its mechanical, physical, and biological properties is crucial for enhancing its efficiency.

: to address the issue of burst drug release in antibiotic-loaded poly(methyl methacrylate) (PMMA) bone cement (ALBC), this study involved preparation of novel PMMA bone cement and determination of its antibacterial activity, biocompatibility, compressive properties, maximum temperature, and setting time. : a novel acrylic monomer, which contains the 3,4-dichloro-5-hydroxyfuran-2(5)-one (DHF), was synthesized and utilized to develop non-leaching antibacterial PMMA bone cement (NLBC), designated as DHF-methacrylic acid (DHF-MAA) bone cement. In the preparation of this bone cement, DHF-MAA served as a key component of the liquid phase.

Introduction: Giant cell tumor of bone (GCTB) ranks among the most prevalent locally aggressive tumor lesions, displaying a diverse range of biological behaviors. Recurrence of GCTB is well-documented, often attributed to microscopic tumour remnants remaining after intralesional curettage, with increased concern when infection occurs postoperatively. Studies suggest the limited effectiveness of adjuvants in preventing giant cell tumour recurrence, emphasizing the necessity of complete removal of malignant cells.

Objectives: Comparative evaluation of indirect pulp therapy (IPT) with silver diamine fluoride (SDF), Type VII glass ionomer cement (GIC), and calcium hydroxide (Ca(OH)2) in young permanent molars.
Materials And Methods: This was randomized controlled trial, in which 45 children with 60 young permanent first molars were allocated as; Group A: IPT with SDF, Group B: Type VII GIC, and Group C: Ca(OH)2. Clinical and radiographic evaluation and comparison was done at baseline, 3, 6, 12 months.
