    Notizen: Summary Eighty-nine patients, 33 men and 56 women, with early definite rheumatoid arthritis were followed for 2 years. Two-thirds were seropositive. About 1/3 were eventually treated with second line drugs. The disease mostly had an insidious onset initially involving the finger joints. Early remission occurred in 16%. Patient relevant measures such as pain, patient's overall assessment of disease activity and anxiety decreased significantly. Disability evaluated by the HAQ disability index remained at a low level. The joint damage score (JDS) in hands and feet increased steadily and only 18% were nonerosive after 2 years. One-third developed hand deformities which was associated with higher JDS. A joint function index (SOFI) correlated significantly with JDS. Twenty-eight percent had a slower rate of joint damage progression the second year. There was no significant correlation between JDS and disease duration. Six patients developed rapidly progressive damage in larger joints, five in the hip joints and one in the shoulder joint, all requiring joint replacement. The ability to predict outcomes with clinical and laboratory variable obtained at entry was of limited clinical usefulness. By applying discriminant analyses 67%–80% of the cases who fared worst regarding clinical, functional, and radiological features could be correctly classified.

    Notizen: Abstract The objective of this study was to evaluate a pulsed laser transillumination technique based on time-resolved detection on breast-tissue-like phantoms. Experiments have been performed on tissue-like plastic phantoms with different scattering characteristics. The effects of time-gate width, size, localisation and refractive index of hidden objects have been scrutinised. Our study showed that the shorter the time-gate the higher the contrast. The contrast is very dependent on the size of the hole, whereas the full width half maximum is not. Furthermore, the investigation showed that the changes of early detected light in an experimental setting is due to scattering, and not to a higher speed of the transmitted light
