A prospective study was undertaken to compare the accuracy of surface coil magnetic resonance (SCMR) imaging, metrizamide myelography (MM), and computed tomography with metrizamide (CTM) in the determination of cervical radiculopathy. Surgical findings were the objective measure of accuracy. Fifty-two patients underwent all imaging studies. Studies were evaluated for disease location and type (bone vs. soft tissue). Twenty-eight patients underwent subsequent cervical surgery at 39 levels form an anterior interbody approach. Predictions made with SCMR imaging were surgically confirmed in 74% of patients, with CTM in 85%, and with MM in 67%. There was 90% agreement with surgical findings when SCMR imaging and CTM were used jointly, and 92% agreement when CTM and MM were used jointly, In general, SCMR imaging was as sensitive as CTM for identification of disease level, but not as specific for type of disease. MM was the modality least specific for disease type. The major advantage of CTM was its ability to distinguish bone from soft tissue, for which contrast material is unnecessary. SCMR imaging is a viable alternative to MM and, together with computed tomography, if needed, provides a thorough examination of the cervical region.  相似文献

Cervical radiculopathy: value of oblique MR imaging   总被引:2,自引:0,他引:2  
Eighteen patients with cervical radiculopathy were entered into a prospective study to compare the accuracy of surface coil magnetic resonance (MR) imaging with that of metrizamide myelography and computed tomography (CT) with metrizamide. All MR studies included tailored axial and oblique images as well as routine sagittal images. All imaging studies were evaluated for topography and type of disease. Nine of 18 patients subsequently underwent cervical surgery with an anterior interbody approach at 11 levels. The surface coil MR findings concerning disease topography and type concurred with the surgical findings at nine of 11 levels (82%). At three levels, the oblique view added important information not available on the sagittal images or clarified changes seen on the axial images. Metrizamide myelography with CT metrizamide myelography had findings concurrent with surgical findings at ten of 11 levels (91%).  相似文献

We administered a combination of rubidazone, cytosine arabinoside, vincristine, and prednisone (ROAP) to 91 patients with acute myelogenous leukemia who were 50 yr of age or older. These patients had been identified in previous studies to be a group with a relatively poor prognosis. One-third of the patients had an antecedent hematologic disorder prior to treatment. Forty patients (48%) obtained a complete hematologic and clinical remission. A history of an antecedent hematologic disorder, male sex, and absence of Auer rods were adverse factors for achieving remission in this older population. More than half of the patients achieved remission in one course. The major cause of failure to obtain a remission was death due to infection, 40% of which were caused by fungi. Resistance to chemotherapy, although uncommon, was noted more frequently in patients with an antecedent hematologic disorder. Univariate and multivariate prognostic factor analysis was used to compare these patients with a historical control group treated with a program in which adriamycin was used instead of rubidazone (AdOAP). No significant difference in remission rate was detected. Cyclocytidine was used as a maintenance agent in this study, and while the median remission duration was only 37 wk, 30% of patients are expected to be in remission for 2 yr. Chemotherapy programs combining an anthracycline with cytosine arabinoside, given to older patients in similar fasion to younger patients will achieve remissions in one-half of a group of older patients. These remissions are of comparable quality to those of younger patients. Mathematical models derived from analysis of prognostic factors are of use in identifying patients likely to fail these programs who are in need of innovative approaches to treatment.  相似文献

Monocyte-mediated inhibition of lymphocyte blastogenesis in Hodgkin disease   总被引:8,自引:0,他引:8  
Schechter  GP; Soehnlen  F 《Blood》1978,52(2):261-271
Mononuclear leukocytes isloated from the blood of previously treated patients with advanced active Hodgkin disease contained high concentrations of monocytes and showed poor lymphocyte blastogenesis to mitogens. In five of eight patients with disseminated disease, blastogenesis became normal or improved markedly when the leukocyte suspensions were depleted of monocytes before culture. Addition of autologous macrophages to the monocyte-depleted lymphocytes resulted in a reappearance of the inhibition of blastogenesis. Monocyte inhibition was associated with the presence of active disease, lymphocytopenia, and low lymphocyte/monocyte ratios in the peripheral blood. The role of previous treatment is uncertain, since inhibition tended to disappear when the patients were retreated. Inhibitory monocyte-lymphocyte interactions may be one of the causes of impaired cell-mediated immunity in Hodgkin disease.  相似文献

SUMMARY Patients with endoscopically confirmed oesophagitis (n=49) were treated for 8 weeks with either cisapride (10 mg four times a day) or ranitidine (150 mg twice a day) in a double-blind study in general practice. Mean overall symptom scores fell from 10.8 to 4.5 in the cisapride group and from 9.9 to 4.4 in the ranitidine group over the course of the study. The proportion of patients reporting improvements in individual symptoms in the two treatment groups (cisapride and ranitidine respectively) were: heartburn, 66% and 55%; acid regurgitation, 53% and 47%; epigastric pain, 60% and 52%; satiety, 57% and 47%; bloating, 69% and 71%; belching, 65% and 72%; nausea, 62% and 85%; vomiting, 77% and 66%; poor appetite, 50% and 75%. Improvement in the endoscopic grade of oesophagitis was observed in 66% of patients receiving cisapride and 63% of those receiving ranitidine. It was concluded that cisapride is as effective as ranitidine in relieving the symptoms of oesophagitis and in healing oesophageal erosions.  相似文献

In a multiclinic double-blind trial, 305 patients with moderate to severe acne vulgaris were treated with oral tetracycline hydrochloride, 250 mg (N: 103), a 1% solution of clindamycin phosphate (N: 105), or placebo (N: 97) twice daily for 8 weeks. The response to treatment was evaluated by lesion counts and overall clinical improvement at 2, 4, 6, and 8 weeks. Both topical clindamycin and oral tetracycline significantly reduced papule and pustule counts compared to placebo; they were rated significantly higher than placebo on the physician's and the patient's overall evaluation at the end of the treatment period. No serious side effects were reported with any of the study medications.  相似文献
