Uso de um distrator ósseo dentoimplantossuportado, feito a partir de tornos expansores convencionais, na reabilitação oral

Osteodistraction is a clinical reality, available in the last decades for the resolution of large bone deficiencies, in cases that there are pre-existing, but misplaced implants and teeth. The aims of thearticle is to present a case report in which a new possibility for bone distraction, based on tooth-implant bone distractors, made from standard orthodontic expansion-screws, was used in an area where there was an extensive need of alveolar bone and aesthetical recovery, allied to teeth and dental implant misplacement. This technique presented good clinical results, associated to effective simplicity and low cost, becoming viable clinical solution for bone tissue augmentation and aesthetical optimization. In resume, it is possible to say that the suggested technique achieved its objectives, improving the hard and soft tissue profile, whilst allowing completion of oral rehabilitation.

Clinical presentation, etiology, and outcome of infective endocarditis in the 21st century: the International Collaboration on Endocarditis-Prospective Cohort Study.

We sought to provide a contemporary picture of the presentation, etiology, and outcome of infective endocarditis (IE) in a large patient cohort from multiple locations worldwide. Prospective cohort study of 2781 adults with definite IE who were admitted to 58 hospitals in 25 countries from June 1, 2000, through September 1, 2005. The median age of the cohort was 57.9 (interquartile range, 43.2-71.8) years, and 72.1% had native valve IE. Most patients (77.0%) presented early in the disease (<30 days) with few of the classic clinical hallmarks of IE. Recent health care exposure was found in one-quarter of patients. Staphylococcus aureus was the most common pathogen (31.2%). The mitral (41.1%) and aortic (37.6%) valves were infected most commonly. The following complications were common: stroke (16.9%), embolization other than stroke (22.6%), heart failure (32.3%), and intracardiac abscess (14.4%). Surgical therapy was common (48.2%), and in-hospital mortality remained high (17.7%). Prosthetic valve involvement (odds ratio, 1.47; 95% confidence interval, 1.13-1.90), increasing age (1.30; 1.17-1.46 per 10-year interval), pulmonary edema (1.79; 1.39-2.30), S aureus infection (1.54; 1.14-2.08), coagulase-negative staphylococcal infection (1.50; 1.07-2.10), mitral valve vegetation (1.34; 1.06-1.68), and paravalvular complications (2.25; 1.64-3.09) were associated with an increased risk of in-hospital death, whereas viridans streptococcal infection (0.52; 0.33-0.81) and surgery (0.61; 0.44-0.83) were associated with a decreased risk. In the early 21st century, IE is more often an acute disease, characterized by a high rate of S aureus infection. Mortality remains relatively high.
