Progressive knowledge loss: a longitudinal case study.

The evolution of the progressive loss of semantic knowledge of a patient, VZ, with lesions mainly affecting the infero-medial temporal lobes, was followed for two years. At the beginning of the study VZ's performance was mainly characterized by a category-specific deficit for living things and a modality-specific deficit for perceptual attribute knowledge. As time went on, VZ's disorder affected all categories by changing the relationship between category and attribute knowledge. Data show that dissociations may change in the course of progressive cognitive breakdown, depending on both degeneration stage and task demands. VZ's performance is discussed in the light of the most influential theoretical accounts. Methodological suggestions regarding longitudinal studies of degenerative patients are also put forward.

Intraforaminal O(2)-O(3) versus periradicular steroidal infiltrations in lower back pain: randomized controlled study.

BACKGROUND AND PURPOSE: Reports about steroids and oxygen-ozone therapy to treat lower back pain have been increasing. The purpose of our study was to compare the clinical outcomes in patients treated with infiltrations of O(2)-O(3) gas or steroids at short-, medium-, and long-term follow-up. METHODS: A total of 306 patients (166 with primarily disk disease, 140 with nondisk vertebral disease) with acute or chronic low back and sciatic nerve pain received a CT-guided intraforaminal infiltration of an O(2)-O(3) gas mixture or an periradicular infiltration of steroids. Neurologists unaware of the type of treatment assessed the patients. RESULTS: At 1-week follow-up, most patients had a complete remission of pain, regardless of the treatment. At 6-month follow-up, differences in favor of O(2)-O(3) treatment were significant in patients with disk disease (P = .0021) but not in those without disk disease (P = .0992). Clinical outcomes were poor in 13 (15.1%) of 86 patients receiving O(2)-O(3) infiltration and in 18 (22.5%) of 80 patients receiving steroid injection (P = .2226). Among patients without disk disease, six (8.6%) of 70 patients receiving O(2)-O(3) infiltration but 21.4% of the patients receiving steroid injections had poor outcomes (P = .0332). CONCLUSION: Oxygen-ozone treatment was highly effective in relieving acute and chronic lower back pain and sciatica. The gas mixture can be administered as a first treatment to replace epidural steroids.
