Underuse of screening mammography by family physicians 总被引:3,自引:0,他引:3
Although the American College of Radiology, the National Cancer Institute, and the American Cancer Society recommend screening mammography for women more than 40 years old, there is little compliance with these recommendations. Primary-care physicians are often reluctant to refer patients for the procedure, whereas the patients are usually willing to undergo the procedure. This survey documents the underuse of screening mammography by family physicians who are members of the Michigan Academy of Family Physicians. The underuse of mammography by this physician sample was due to two main factors: The physicians perceived far more disadvantages than advantages with mammography and perceived problems (with, e.g., equipment, effectiveness, and patient acceptance) as pervasive. To change the attitudes and referral behavior of family physicians, one must take into account the specific, negative perceptions of the procedure and place an emphasis on the initial referral, since subsequent referrals are easier to implement. 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

Electroconvulsive therapy (ECT) is the most effective treatment for severe depression but its neurocognitive mechanisms are unclear. This randomized, sham-controlled functional magnetic resonance imaging (fMRI) study explored the effects of a single ECT on neural response to affective pictures. Twenty-seven patients with major depressive disorder were randomized to a single active ECT (N?=?15) or sham (N?=?12) session in a double-blind, parallel-group design. On the following day, patients underwent fMRI during which they viewed pleasant, unpleasant and neutral pictures and performed a free recall test after the scan. Mood symptoms were assessed before ECT/sham and at the time of fMRI. Subsequently, all patients continued active ECT as usual. Mood symptoms were reassessed after six active ECT sessions. A single ECT vs. sham session reduced neural response to unpleasant vs. pleasant pictures in the medial prefrontal cortex, a region showing greater response in the more depressed patients. This effect occurred in the absence of between-group differences in picture recall, mood symptoms or concomitant medication. In conclusion, modulation of medial prefrontal hyper-activity during encoding of negative affective information may be a common mechanism of distinct biological depression treatments. 相似文献
