Effectiveness of soy milk with calcium on bovine enamel erosions after soaking in chlorinated water.
We determined the effectiveness of soy milk with calcium for prevention of enamel erosion caused by chlorinated water. Thirty-six bovine teeth without wear or caries, sized 8 x 10 mm, were placed in resin acrylic blocks. All specimens had an initial enamel microhardness of 270-320 VHN and were randomly allocated into 3 groups (n = 12/group): control (not treated), casein phosphopeptide-amorphou...
Objectives. Ultrasonography (US) is a sensitive tool for detecting erosions in patients with RA. The wrist is usually involved in the RA process, where the distal ulna with its superficial localization is easily accessible for US examination. In this longitudinal study, we wanted to examine the presence, localization and development of erosions at the distal ulna by US in patients with recent o...
OBJECTIVE To assess the ability of ultrasonography (US) to predict radiographic damage in early arthritis. METHODS ESPOIR is a multicentric cohort of early arthritis (i.e., ≥2 swollen joints between 6 weeks and 6 months). US synovitis in B mode, power Doppler (PD) mode, and erosions were searched on the second through the fifth metacarpophalangeal and fifth metatarsophalangeal joints accordin...
BACKGROUND The objectives of the present study were, with multidetector computed tomography (CT) as the reference method, to determine the performance of magnetic resonance imaging (MRI) and radiography for the detection of bone erosions in rheumatoid arthritis wrist bones, and to test whether measuring volumes of erosions on CT and MRI is reproducible and correlated to semiquantitative assessm...
The objective of the study was, with multidetector computed tomography (CT) as the reference method, to determine whether bone erosions in rheumatoid arthritis (RA) metacarpophalangeal (MCP) joints detected with magnetic resonance imaging (MRI) and ultrasonography (US), but not with radiography, represent true erosive changes. We included 17 RA patients with at least one, previously detected, r...
A 52-year-old Japanese woman who was eventually diagnosed with primary follicular lymphoma of the duodenum showed atypical endoscopic features, namely, erosions with peripheral whitish edematous mucosa. Initial biopsy specimens taken from the erosions revealed insufficient numbers of lymphoma cells for histological diagnosis. Subsequent biopsy specimens from the peripheral mucosa containing the...
We read with interest the pictorial essay on ultrasonography of bone erosions by Grassi and colleagues. The presented site-specific comparison of radiographic and sonographic imaging of metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joint sites in rheumatoid subjects suggests strongly a homology of the erosive lesions, as visualised by these diVerent imaging modalities. A recently publ...
