To determine the long-term outcome after fusion for adolescent idiopathic scoliosis in terms of degenerative disc findings diagnosed using MR imaging and to elucidate the clinical consequences. ⋯ There were significantly more degenerative disc changes (p<0.0001), disc height reduction (p=0.0010) and end-plate changes (p<0.0001 for both upper and lower end-plates) in the lowest unfused disc in the patient group compared with the control group. The MR findings in the lowest unfused disc, but not the one above, in the patient group correlated to lumbar pain intensity as well as to the diminished lumbar lordosis.

Comparative Study
Perfusion-related parameters in intravoxel incoherent motion MR imaging compared with CBV and CBF measured by dynamic susceptibility-contrast MR technique.
Perfusion-related parameters obtained by intravoxel incoherent motion (IVIM) MR imaging (MRI) were compared with cerebral blood volume and flow (CBV and CBF), retrieved by dynamic susceptibility-contrast (DSC) MRI. ⋯ The IVIM concept provided results that agreed reasonably with conventional CBV and CBF. The non-linear fitting to noisy signal data was problematic, in accordance with previously presented simulations.

To establish radiographic criteria to choose the most appropriate technique of reduction for each type of anterior glenohumeral dislocation, and to determine the type of dislocation which requires general anesthesia. ⋯ Anterior dislocations of the shoulder require different methods of reduction depending upon the type (sub-group) of dislocation. Reduction of subglenoid dislocations with associated greater tuberosity fracture should be performed under general anesthesia to avoid head-splitting fracture.

To evaluate the nephrotoxicity of high- and low-osmolar contrast media (HOCM, LOCM) on kidneys in Sprague-Dawley rats. The protective role of amlodipine was studied. ⋯ The HOCM, diatrizoate, was more toxic to rat kidneys than the LOCM iohexol; PLA2, LPO and calcium load played a role in producing renal function impairment induced by diatrizoate meglumine; amlodipine protected the renal tissue from nephrotoxicity induced by diatrizoate.
