[Ultrasonography in the study of synovial disorders and tendon lesions in rheumatoid arthritis]. / L'ecografia nello studio delle alterazioni sinoviali e delle lesioni tendinee nell'artrite reumatoide.

Conventional radiology is the main diagnostic tool for the visualization of osteoarticular lesions in rheumatoid arthritis. Articular effusions and popliteal cysts were examined with US. This paper is aimed at proving US capabilities in yielding important information about articular and peri-articular soft tissues in the early phases of rheumatoid arthritis. Over the last 30 months, the shoulder, wrist, hand, knee, and hip of 73 rheumatoid patients were studied by means of US and conventional and microfocal radiography. The patients were divided into 2 groups according to the time of onset of the disease. In group A, US demonstrated early synovial exudative inflammation, whereas conventional and microfocal radiography mainly demonstrated soft tissue swelling. In group B (where the first onset dated back to over 1 year), US demonstrated exudative and proliferative changes, together with recurrences. The authors believe US to be able to recognize the early changes of rheumatoid arthritis: as a matter of fact, US shows articular and periarticular soft tissues abnormalities and allows a differential diagnosis to be made between exudative and proliferative forms.

[Echographic examination in the screening of hip dysplasia in newborn infants and infants]. / L'indagine ecografica nello screening della displasia dell'anca del neonato e del lattante.

Sonography was employed to evaluate the accuracy of congenital hip dysplasia in 1014 cases, using Graf's methodology and classification in neonatal and infant age. Sonography appears useful to detect and monitor this disease. In fact all the acetabular development can be better revealed than by radiography.
