Oblique radiographs are often ordered to evaluate the patency of cervical intervertebral foramina. Previous studies have shown that computed tomography (CT) provides accurate measurements of foraminal dimensions. Up until now, no study has directly compared the diagnostic utility of oblique radiographs and CT. We conducted a study to quantify the correlation between cervical foramina dimensions measured on oblique radiographs and on CT scans. Heights, widths, and cross-sectional areas were evaluated at every level from C2-C3 through C7-T1 using both oblique radiographs and oblique CT reconstructions. Both measurements were performed at a 50% oblique angle. Interreliability and intrareliability statistics for radiographs and CT were 0.91 and 0.99 for height, 0.90 and 0.97 for width, and 0.84 and 0.92 for area. Pearson correlation coefficients for height, width, and area were 0.439, 0.871, and 0.899, respectively. Oblique radiographs of the cervical spine provide accurate estimates of intervertebral foraminal dimensions--estimates similar to those generated from CT reconstructions. Thus, these radiographs may serve as an acceptable first-line imaging study for initial assessment of patients suspected of having nerve root compression that precludes the higher cost and radiation exposure associated with CT scans. 相似文献

STUDY OBJECTIVE: To study whether there is any difference in the clinical characteristics between the two patterns of perfusion lung scan of idiopathic pulmonary arterial hypertension (normal vs. diffuse, multiple ill-defined defects) and whether the perfusion lung scan patterns of these patients would predict the effect of long-term use of beraprost sodium. METHODS: We evaluated 27 patients who used beraprost sodium for over 3 months, and noted a diffuse patchy pattern in 13 cases and a normal pattern in the remaining 14 cases. We judged that beraprost sodium was effective when at least two of the following conditions were met: improvement in symptom of dyspnea, more than 10% decrease in peak velocity of tricuspid valve regurgitation by echocardiography (Vmax), or more than 10% increase in 6-min walking distance. RESULTS: At baseline there was no difference between the two groups in dyspnea, hemodynamic parameters, and 6-min walking distance. After the use of beraprost sodium, the normal group showed improvement in dyspnea, 6-min walking distance, and Vmax. But the diffuse patchy group showed no improvement. The use of beraprost sodium in the normal group was effective in 10 out of 14 cases, but was effective in only two out of 13 cases in the diffuse patchy group. CONCLUSION: Perfusion lung scan pattern in patients with idiopathic pulmonary arterial hypertension is a useful prognostic indicator of the response to beraprost sodium. 相似文献

Leclercia adecarboxylata, a motile, gram-negative bacillus of the enterobacteriaceae family, is rarely recovered as a pathogen. We report an exceptionally rare case of L. adecarboxylata endocarditis complicated by embolization of the kidney and spleen in a 48-year-old woman with endometrial cancer. After 4 weeks of antimicrobial treatment, she recovered without sequelae. 相似文献

This study investigated effect of extract containing quercetin-3-O-β-D-glucuronopyranoside from Rumex Aquaticus Herba (ECQ) against chronic gastritis in rats. To produce chronic gastritis, the animals received a daily intra-gastric administration of 0.1 ml of 0.15% iodoacetamide (IA) solution for 7 days. Daily exposure of the gastric mucosa to IA induced both gastric lesions and significant reductions of body weight and food and water intake. These reductions recovered with treatment with ECQ for 7 days. ECQ significantly inhibited the elevation of the malondialdehyde levels and myeloperoxidase activity, which were used as indices of lipid peroxidation and neutrophil infiltration. ECQ recovered the level of glutathione, activity of superoxide dismutase (SOD), and expression of SOD-2. The increased levels of total NO concentration and iNOS expression in the IA-induced chronic gastritis were significantly reduced by treatment with ECQ. These results suggest that the ECQ has a therapeutic effect on chronic gastritis in rats by inhibitory actions on neutrophil infiltration, lipid peroxidation and various steps of reactive oxygen species (ROS) generation. 相似文献
