Objectives: The aim of this study was to evaluate the incidence of bleeding complications after dental implant placement in patients in treatment by the oral anticoagulant dabigatran following a specific protocol.
Material And Methods: Seventy-one patients were divided into two groups: 29 had been taking dabigatran for over 6 months (150 mg orally every 12 h) before implant surgery (dabigatran group) and a control group consisting of 42 healthy subjects. Patients were treated in an outpatient setting. All subjects received dental implants in different positions, dabigatran group patients 12 h after the last dose of dabigatran. Nonabsorbable sutures were used and patients were given gauzes impregnated with tranexamic acid 5% to bite on for 30-60 min. Dabigatran patients resumed medication 8 h after the procedure, resuming usual dosage (every 12 h) the day after surgery.
Results: Two dabigatran patients and two control patients presented slight bleeding the day after surgery. Bleeding was managed with gauzes impregnated with tranexamic acid. No statistically significant differences (P = 0.542) were found in relation to bleeding episodes between the groups, with a relative risk of 0.675 based on the pooled groups and a 95% confidence interval of 0.090-5.088.
Conclusions: Dental implant surgery in patients taking dabigatran can be performed safely providing 12 h have passed since the last dose and local hemostatic measures are applied. Normal dosage can be resumed 8 h after implant surgery.

We report the case of a 72-year-old male patient who presented with a progressive aortic arch aneurysm. To reduce surgical trauma, we planned the procedure using an upper partial sternotomy with continuous cardiac perfusion and moderate hypothermia. Two vents were inserted to provide sufficient relief to the heart during perfusion.

Background And Purpose: Early migration of the uncemented cruciate-sacrificing rotating platform ATTUNE and Low Contact Stress (LCS) tibial components was classified as at-risk for aseptic loosening rates exceeding 6.5% at 15 years based on recent fixation-specific migration thresholds. In this secondary report of a randomized controlled trial (RCT) we aimed to evaluate whether the 5-year migration, inducible displacement, and the clinical outcome of the ATTUNE components were comparable to those of the LCS.

In dental implant surgery, infection is identified as the primary factor contributing to the failure of bone grafts. There is an urgent need to develop bone graft materials possessing antibacterial characteristics to facilitate bone regeneration. Magnesium phosphate bone cement (MPC) is highly desirable for bone regeneration due to its favorable biocompatibility, plasticity, and osteogenic capabilities.

Adipose tissue engineering requires effective strategies for regenerating adipose tissue, with adipose-derived stem cells (ASCs) being favored due to their robust self-renewal capacity and multipotent differentiation potential. In this study, the efficacy of poly-L-lactic acid (PLLA) mesh containing collagen sponge (CS), seeded with ASCs to promote adipose tissue formation, was investigated. PLLA-CS implants seeded with GFP-positive ASCs were inserted at high concentration (1 × 10 cells/implant, H-ASC) and low concentration (1 × 10 cells/implant, L-ASC), as were unseeded controls.

Background: Penile implant surgery is the standard surgical treatment for end-stage erectile dysfunction. However, the growing complexity of modern high-tech penile prostheses has increased the demand for more practical training opportunities. The most advanced contemporary training methods involve simulation training using cadavers, with costs exceeding $5,000 per cadaver, inclusive of biohazard fees.
