MR arthrography of the shoulder with patients in the ABER position may provide additional information in cases of partial-thickness tears of the rotator cuff with a horizontal component.

Twenty-five patients have completed a mean of 53 months of treatment with methotrexate (MTX) as part of a prospective study of the long-term safety and efficacy of the drug. Since the time of the last report (at a mean of 29 months), the mean dosage of MTX has increased from 12.4 mglweek to 14.6 mglweek, whereas the mean prednisone dosage has decreased from a baseline of 7.1 mg/day to 1.9 mglday. A significant improvement from baseline in all clinical parameters tested was maintained, and response to therapy did not vary significantly between the assessment at 29 months and that at 53 months.Toxic reactions were as common during months 3&53 as during the first 29 months of the study, with patterns of toxic reactions remaining consistent within each patient. Radiologic evidence of disease progression was not seen before 24 months of MTX treatment, but after this time, it was observed in some patients. We conclude that many clinical features of long-term MTX therapy are distinctly different from what might have been expected after the short-term trials.Methotrexate (MTX) is an effective agent in the short-term treatment of refractory rheumatoid arthritis

MR imaging is useful for evaluation of associated soft-tissue injuries in patients with the arcuate sign on conventional radiographs. Avulsion injury to the proximal fibula is an important indicator of the internal derangement of the knee and for predicting the mechanism of an injury with varus stress. Cruciate ligament tear and bone bruises on the anteromedial condyle of the femur and tibia are common associated findings.

The use of abduction and external rotation in shoulder MR arthrography can be a helpful tool that complements sequences that use conventional positions for characterizing a variety of abnormal conditions in the shoulder.

In this work, we demonstrate an extremely simple but highly effective strategy for the synthesis of various functional metal oxides (MOs) such as ZnO, In2O3, Bi2O3, and SnO2nanoparticles with various distinct shapes at room temperatureviaa solid-state reaction method.
