[Redifferentiation therapy with rosiglitazone in a case of differentiated thyroid cancer with pulmonary metastases and absence of radioiodine uptake].

Treatment with radioiodine (RDI) has been shown to be an effective option in patients with differentiated thyroid cancer with recurrent or metastatic disease. However, in spite of having elevated levels of thyroglobulin in blood, in some of these patients, the whole body scan does not detect radioiodine uptake due to loss of differentiation of the neoplastic cells, thus leading to loss of efficacy of the treatment. That is why drugs with potential differentiating properties, like rosiglitazone or retinoids, are being studied.

The septic versus nonseptic inflamed joint: MRI characteristics.

Objective: To differentiate the MR features of septic versus nonseptic inflamed joints.

Design And Patients: Thirty patients were referred for MRI with inflamed joints (19 were subsequently found to be septic and 11 nonseptic). At 1.

Synovial effusion in reflex sympathetic dystrophy: an additional sign for diagnosis and staging.

Purpose: To improve the present MRI criteria for diagnosis and staging of reflex sympathetic dystrophy (RSD) by including increased joint fluid as an additional MRI sign of RSD.

Design And Patients: One hundred and fourteen extremities (69 affected and 45 contralateral controls) in 57 consecutive patients with RSD were evaluated using a 1.5-T unit.

Color Doppler hemodynamic evaluation of flow to normal hip.

This study was aimed to quantitate hemodynamic flow to the normal proximal femur and to evaluate the effect of internal rotation on blood flow measurements in the hip to assess the capability of Doppler ultrasonography to detect a simulated ischemic situation. Forty hips in 20 adult healthy volunteers age 22 to 62 years (mean age, 39.5 years) were examined in the supine position in neutral position and during internal rotation (simulated ischemia).
