S100B as a predictor of size and outcome of stroke after cardiac surgery.

Background: Stroke after cardiac surgery is a clinical problem with often fatal or disabling outcome. To assess severity and probable outcome in affected patients only from clinical and radiological examinations is difficult. The glial-derived protein S100B has been suggested to be a marker of cerebral ischemia, and increased blood concentrations of S100B have been shown to correlate with size of lesion and prognosis after stroke.

Quantitative contrast-enhanced MR imaging of the optic nerve.

During the acute stages of optic neuritis damage to the blood-optic nerve barrier can be detected using i.v. paramagnetic contrast-enhanced MR imaging.

Characterization and functional assessment of patients subjected to occipito-cervical fusion for rheumatoid atlanto-axial dislocation.

20 patients with rheumatoid arthritis and atlanto-axial dislocation subjected to occipito-cervical fusion were studied. The patients were evaluated by a rheumatologist before surgery and 6-12 months after the fusion procedure. Joint tenderness was assessed by Ritchie's Index while the functional capacity was evaluated using a health assessment questionnaire and according to the classification by Steinbrocker.

Relationship between 99Tcm-MDP uptake and bone mineral density in patients with prostatic carcinoma.

Seventeen men with prostatic carcinoma were investigated with quantitative bone scintigraphy and quantitative computed X-ray tomography before orchiectomy and up to 6 months after this operation. The uptake of 99Tcm-labelled methylene disphosphonate (99Tcm-MDP) and bone mineral density (BMD) were determined for each vertebra from Th10 to L4. Ten patients had normal scintigrams.

Radiology of the pharynx and oesophagus in young adults.

The indication for and results of radiological examination of the pharynx in 195 young adults (83 men, 112 women; age 13-40 years) were analysed retrospectively. A total of 99 patients were examined because of a suspected foreign body. In only seven was a foreign body revealed; two patients had mucosal tears.
