Filter by:Purpose: The aim of this study was to investigate the influence of surface characteristics and geometric design on marginal bone loss and bone quality in dental implants. Materials and Methods: A total of 378 implants from 114 patients were evaluated in this study using panoramic and periapical radiographs. Implants were categorized into 19 subgroups according to the jaw where they were placed, length, diameter, surface preparation, type of prosthetic superstructure, and neck design. Radiological evaluations were conducted based on radiographs obtained at the time of implant placement and 3 months after prosthetic loading. After obtaining measurements of marginal bone loss and fractal analysis data, the significance of differences between groups was statistically evaluated.
End-stage heart failure in children is a rare cause of infant mortality. The most frequent cause is dilated cardiomyopathy, often of undetermined origin, which can lead to cardiogenic shock refractory to standard medical treatment. In such cases, it is essential to resort to exceptional means, available at tertiary care hospitals such as in Lyon. The therapeutic means includes long-term circulatory assistance (VAD). This type of circulatory assistance is becoming increasingly used in view of the shortage of heart transplants. Indeed, the average waiting time on the paediatric transplant list varies from 3 months to over a year for children under 5. Berlin Heart EXCOR (BHE) is the only long-term support available for children (2). It is a pulsatile para-corporeal assisting device with percutaneous cannulas. Despite technical and medical advances in circulatory support, the presence of foreign material is frequently complicated by infection. Infection is a major cause of morbidity and mortality in this population. It is most often of nosocomial origin, linked to central line infections. The germs associated with these infections are mainly bacteria, with a small proportion of fungi. The most common pathogens are multi-resistant gram-positive bacteria, which colonize the skin, adhere to the implanted equipment and create biofilms. Infections have a major impact on the morbidity and mortality of patients undergoing mechanical assistance, with an increased risk of thrombo-embolic events and difficulty in managing anticoagulation, secondary to inflammation.
