BACKGROUND Behçet's syndrome (BS) is a multisystem immune-related disease of unknown etiology. Recurrent aphthous stomatitis (RAS) is characterized by the presence of idiopathic oral ulceration without extraoral manifestation. The interplay between the oral microbial communities and the immune response could play an important role in the etiology and pathogenesis of both BS and RAS. OBJECTIVE...
Asthma is a heterogeneous disease whose etiology is poorly understood but is likely to involve innate responses to inhaled microbial components that are found in allergens. The influence of these components on pulmonary inflammation has been largely studied in the context of individual agonists, despite knowledge that they can have synergistic effects when used in combination. Here we have expl...
This article presents findings from two studies that describe news portrayals of cancer causes and prevention in local TV and test the effects of typical aspects of this coverage on cancer-related fatalism and overload. Study 1 analyzed the content of stories focused on cancer causes and prevention from an October 2002 national sample of local TV and newspaper cancer coverage (n = 122 televisio...
Australia experienced a large influx of European migrants during the period 1950-1975. The descriptive epidemiolÃ3gica! data on cancer rates within the major migrant groups, reviewed here, provide strong evidence of environmental and behavioral influences on the etiology of various cancers. The opportunity to extend the conventional type of data analysis, to include an examination of the effect...
The microbial infections involving the craniofacial skeleton, particularly maxilla and mandible, have direct relationship with the dental biofilm, with predominance of obligate anaerobes. In some patients, these infections may spread to bone marrow or facial soft tissues, producing severe and life-threatening septic conditions. In such cases, local treatment associated with systemic antimicrobi...
A 39-year-old woman with tubarian sterility fell ill with acute pelvic inflammatory disease 2 months after transvaginal oocyte recovery. Laparotomy revealed a large tuboovarian abscess, from which Atopobium vaginae, an anaerobic gram-positive coccoid bacterium of hitherto unknown clinical significance, was isolated. The microbial etiology and the risk of pelvic infections following transvaginal...
Most periapical lesions resolve after root canal treatment of teeth with primary infections. Over the last decade there has been a renewed focus on post-treatment apical periodontitis and its etiology. This review describes the microbiota associated with persistent post-treatment infection, including microbial identification, ecology, and environmental selection. Compared with untreated teeth, ...
Urinary tract infections (UTIs) are one of the most important causes of morbidity and health care spending affecting persons of all ages. Bacterial biofilms play an important role in UTIs, responsible for persistent infections leading to recurrences and relapses. UTIs associated with microbial biofilms developed on catheters account for a high percentage of all nosocomial infections and are the...
