[Value of imaging in early diagnosis of peripheral vein tumors].

Peripheral venous tumors are uncommon and their delayed clinical expression leads to poor prognosis. We report a series of 7 cases including 6 leiomyosacromas and 1 hemangioendothelioma. Duplex Doppler and MR imaging appeared to be best suited for diagnosis, allowing an evaluation of extension and an analysis of associated endoluminal thrombi.

[Pulmonary cavitated opacity in immunocompromised patient].

Lung abscesses are uncommon in legionellosis and usually are observed in immunocompromised patients. The radiographic presentation may lead to misdiagnosis and subsequently to increased mortality.

[Long-term stability of bone mineral density in patients with renal transplant treated with cyclosporine and low doses of corticoids. Protective role of cyclosporine?].

Objectives: Cyclosporine has been thought to have a deleterious effect on bone in transplant recipients because of high turnover osteopenia observed in humans after transplantation. However, varying confounding factors such as renal and parathyroid function, cumulative steroid doses and previous exposure to aluminium, also play a role and hinder interpretation of the cyclosporine effect on bone mineral density (BMD).

Patients And Methods: A 2-year prospective study was conducted to measure BMD starting 3 months after transplantation and bone remodeling markers from the first post-transplantation day in 52 kidney recipients with no prior exposure to aluminum.

Low bone mineral density and peripheral blood monocyte activation profile in calcium stone formers with idiopathic hypercalciuria.

Calcium stone formers (CaSF) with idiopathic hypercalciuria (IH) have been shown to have decreased bone mineral density (BMD). The mechanism of their bone loss remains obscure. Monokines like interleukin-1 beta (IL-1 beta), IL-6, tumor necrosis factor-alpha (TNF-alpha), and granulocyte macrophage stimulating factor (GM-CSF) are involved in bone remodeling, but only IL-1 excess has been incriminated in the bone loss of CaSF with IH.
