A new classification method for CT/discography was developed. The Dallas discogram description (DDD) related five separate categories of information. Degeneration and annular disruption were regarded as separate phenomena. Additionally, provoked pain response, contrast volume, and miscellaneous information were recorded. Discogram findings of 59 patients(More)
STUDY DESIGN This re-analysis was based on 833 computed tomography/discograms collected from 306 candidates for back surgery. OBJECTIVES The goal was to test the hypothesis that outer anular ruptures are the main determinant of the pain of discography. SUMMARY OF BACKGROUND DATA Previous analyses indicated univariate associations of pain with disc(More)
CT/discograms of 107 low-back patients were classified by annular degeneration, annular disruption, and pain response. These parameters were compared with the heights of the corresponding discs. Disc height correlated significantly with degenerative annular changes. Comparison of the painless and exact reproduction groups at the L5-S1 level showed a(More)
The CT/discographic findings from 225 discs in 91 low-back pain patients were compared to the pain provocation during the injection of contrast into the disc. The radiographic appearance of disc deterioration demonstrating disc degeneration and annular disruption of each disc was classified separately using a fourpoint scale: normal, slight, moderate, or(More)
The noninfectious complications of blood transfusion consist of a diverse group of immune-mediated transfusion reactions that range from immediate life-threatening to subclinical reactions. Each reaction involves the recognition and interaction of the both the humoral and cellular immune systems. In the past, many of the noninfectious complications of(More)
Disc deterioration and pain provocation in different low-back pain syndromes was studied using computed tomography (CT) discography. Data were prospectively collected for 300 patients (816 discs). Patients were classified by their pre-discography diagnosis of disc herniation (DH), degenerated disc (DD), lumbar syndrome (LS), lumbar radicular syndrome (LRS),(More)
A small proportion of mouse ascites fluid induced by hybridomas producing monoclonal antibodies or myelomas secreting immunoglobulin yielded staining that was confined to the Golgi zone of certain epithelial cell types in rats and gerbils but not in mice. In addition, a commercial IgG fraction from mouse plasma similarly labeled the Golgi area, unlike IgG(More)
The computed tomography (CT)/discograms and discographic pain provocation reports of 291 clinical patients, 790 discs (mean age, 38; range, 17-79) were collected. The CT/discograms were classified separating anular disruption and degeneration and recording the pain provoked during discography as no pain, dissimilar, similar, or exact reproduction of the(More)
