indicated for aorta endarterectomy due to myocardial infarction were recruited for periodontal clinical examination. The microbial diversity of atherosclerotic plaques (n=35) was evaluated by sequence analysis of bacterial 16S rRNA libraries.
Bacterial DNA was detected in 12 endarterectomy specimens (34.3%). Twenty-three bacterial species/phylotypes were identified. Proteobacteria and Firmicutes comprised 78.3% and 21.7% of the identified taxa, respectively. Fifteen (60.9%) phylotypes were reported as yet uncultivable or as yet uncharacterized species. Two uncultured phylotypes were previously detected in the human mouth. The periodontopathogen Aggregatibacter actinomycetemcomitans was detected in seven samples (20%), followed by Pseudomonas species. There was no association between periodontal parameters and detection of A.actinomycetemcomitans or other phylotypes in atherosclerotic plaques.
Our results suggest a role of the oral microbiota in the development of inflammation in atherogenesis, particularly of A.actinomycetemcomitans.”
“Objective: The purpose of this study was to examine the three-dimensional (3D) progression patterns of
early acetabular cartilage damage in hip dysplasia using high-resolutional computed tomography (CT) arthrography.
Design: Thirty-two dysplastic hips of 26 Japanese symptomatic females including 21 hips in pre-stage of osteoarthritis (Kellgren-Lawrence (K-L) grade 0; mean patient age, 32.0 years) and 11 hips in early stage of osteoarthritis (K-L grade 1 or 2: mean patient age, 32.8 years) were examined. Isotropic selleck compound high-resolutional CT arthrography with an image resolution of 0.5 mm in any orthogonal
direction was performed. A 3D acetabular cartilage model was generated and we evaluated distribution of cartilage thickness in 12 zones after dividing the weight-bearing area of the hip joint in radial and lateral/medial directions.
Results: In pre-stage of osteoarthritis, significant differences in cartilage thickness were observed between the lateral and medial zones in all radial regions, most prominently in the antero-superior region. In early stage of osteoarthritis, no significant differences in cartilage thickness were observed, except in the most posterior region. The lateral medial (LM) ratio was defined as cartilage this website thickness in the lateral zone divided by that in the medial zone, and hips with the LM ratio in the antero-superior region of <1.4 had significantly more extensive involvement of labral tears than hips with the LM ratio of >= 1.4.
Conclusions: In hip dysplasia, acetabular cartilage damage was probably occurred in the antero-superior lateral area. The LM ratio may be a sensitive index to quantify early cartilage damage associated with extent of labral disorders. (C) 2012 Osteoarthritis Research Society International. Published by Elsevier Ltd.
