June 28, 2004   Incidence of hip osteonecrosis among renal transplantation recipients: a prospective study - Clinical Radiology To investigate whether a lessened glucocorticoid cumulative dose would lead to a decreased incidence of femoral head osteonecrosis...Conclusion: Osteonecrosis was uncommon among a prospective cohort of renal transplant recipients within 6 months after engraftment...   Musculoskeletal ultrasound—a state of the art review in rheumatology. Part 1: Current controversies and issues in the development of musculoskeletal ultrasound in rheumatology - Rheumatology As we begin the 21st century, musculoskeletal ultrasound (MSUS) is routinely used by an increasing number of rheumatologists throughout Europe and there is a growing interest in the application of MSUS in rheumatological practice in the UK. MSUS allows high-resolution, real-time imaging of articular and periarticular structures and has the advantages of being non-radioactive, inexpensive, portable, highly acceptable to patients and repeatable... June 25, 2004   Effect of ultrasound on acute inflammation of transected medial collateral ligaments - Archives of Physical Medicine and Rehabilitation Objective To evaluate the effect of therapeutic ultrasound on the acute inflammation of soft-tissue injuries by measuring the levels of prostaglandin E2 (PGE2) and leukotriene B4 (LTB4). Conclusions: Pulsed ultrasound therapy may stimulate inflammation of acute ligament injury...   Ultrasound imaging distinguishes between normal and weak muscle - Archives of Physical Medicine and Rehabilitation Conclusions: Ultrasonography provided a quantitative measure of change between relaxed and contracted state of muscle, which correlated with muscle force. Ultrasound identified significant differences in cross-sectional diameters between the myopathic and normal muscles sampled and may be useful for measuring muscle response to drug and exercise therapy... June 24, 2004   Pigmented villonodular synovitis - Clinical Radiology Pigmented villonodular synovitis (PVNS) is a rare benign proliferative growth of the synovium of obscure aetiology with a wide spectrum of clinical presentations and imaging findings.
