A history of pet contact and/or apparent clinical sensitivity was obtained in 65 (55%) of 118 unselected asthmatic children. These 65 children were skin tested and their sera examined for specific IgE using the radioallergosorbent test. Those children who had apparent clinical sensitivities had larger skin test reactions and were more likely to have positive specific IgE results than those without apparent sensitivities. Positive skin tests were very common (80%), but the larger the skin test reaction (weal diameter greater than 4 mm diameter) the more likely was there to be a positive history or a positive specific IgE result. Hence a large skin test reaction can provide a helpful pointer to animal allergy of clinical importance. Commercially available animal extracts have limitations for diagnostic tests. A questionnaire survey of 150 day schools emphasized the potential opportunities for contact with animal allergens at school. 相似文献

Open-ended interviews with 107 patients documented specific patient expectations of radiologic procedures during which there was no direct radiologist-patient interaction. Patient expectations could be classified into those related to the facility and those related to interactions with radiology staff. Among facility-related expectations, waiting time far outweighed all other concerns. Interpersonal skills were the predominant expectation of radiology staff. The role of the radiologist in fulfilling patient expectations was less clear. Only 10% of unprompted patients cited the radiologist as a factor in their expectations. When patients were specifically prompted to discuss the radiologist's role, communication skills, accuracy of interpretation, and interpersonal skills were the predominant concerns. 相似文献

The present study investigated differences in cognitive coping strategies between anxiety-disordered and non-anxious adolescents. In addition, the interaction effect with gender as well as differences between specific anxiety diagnoses was examined. A clinical sample of 159 anxiety-disordered adolescents and a general community sample of 370 non-anxious adolescents were recruited. Nine cognitive coping strategies were assessed in all adolescents (aged 12-16 years). Results showed that anxiety-disordered adolescents had significantly higher scores on most of the cognitive coping strategies than non-anxious adolescents. The cognitive coping strategies rumination, self-blame and catastrophizing accounted for most of the variance. Gender did not modify the results. Further analyses within the anxiety-disordered sample indicated that adolescents with a generalized anxiety disorder scored significantly higher on rumination, but not on other cognitive coping strategies, than social phobic adolescents. The results suggest that cognitive coping is a valuable target for psychological assessment and treatment in adolescents. 相似文献

Pulmonary embolism after hip or knee replacement: postoperative changes on pulmonary scintigrams in asymptomatic patients 总被引:1,自引:0,他引:1

Serial pulmonary imaging has proved to be effective in the evaluation of patients undergoing total joint arthroplasty. A clinical dilemma arises in asymptomatic patients whose postoperative pulmonary images differ from the preoperative images. The authors prospectively evaluated 403 patients with serial imaging to determine the significance of changed postoperative images in asymptomatic patients undergoing total hip or knee arthroplasty. Twenty-two (5.5%) patients had significant changes on postoperative images. Seventeen were asymptomatic; all but one underwent pulmonary angiography. Documented pulmonary emboli were demonstrated in 100% of patients whose postoperative images changed to indicate a high probability of pulmonary embolism, 71% whose images changed to a moderate probability, and 0% whose images changed to indeterminate probability. Overall, pulmonary emboli occurred in 76% of all asymptomatic patients with significantly change postoperative images. Asymptomatic pulmonary embolism is a significant occurrence after total hip or knee repair, and a changed lung scan with appropriate clinical evaluation is an accurate indicator of pulmonary emboli in asymptomatic postarthroplasty patients. 相似文献

Insertion of a screw biopsy stylet into a thin-walled biopsy needle greatly enhances detection of the needle during ultrasound-guided percutaneous biopsy. This technique is helpful when precise needle-tip localization is needed for biopsies of small lesions. 相似文献

To investigate differences in cognitive coping strategies between anxiety-disordered and non-anxious 9–11-year-old children.
Additionally, differences in cognitive coping between specific anxiety disorders were examined. A clinical sample of 131 anxiety-disordered
children and a general population sample of 452 non-anxious children were gathered. All children filled out the child version
of the Cognitive Emotion Regulation Questionnaire (CERQ-k). Structured clinical interviews were used to assess childhood anxiety
disorders. Results showed that anxiety-disordered children experience significantly more ‘lifetime’ negative life events than
non-anxious children. Adjusted for the ‘lifetime’ experience of negative life events, anxiety-disordered children scored significantly
higher on the strategies catastrophizing and rumination, and significantly lower on the strategies positive reappraisal and
refocus on planning than non-anxious children. No significant differences in cognitive coping were found between children
with specific anxiety disorders. Anxiety-disordered children employ significantly more maladaptive and less adaptive cognitive
coping strategies in response to negative life events than non-anxious children. The results suggest that cognitive coping
is a valuable target for prevention and treatment of childhood anxiety problems. 相似文献

Anti-Sc1 was detected in a gravida-2 patient at 12 weeks' gestation. At 29 weeks, the antibody was found to be of the IgG3 subclass with a titer of 16, score 36, by the indirect antiglobulin test, and it produced 7 percent lysis by antibody-dependent cellular cytotoxicity (ADCC) assay, a finding that suggested an unaffected fetus. The titer remained constant throughout the pregnancy, as did the IgG subclass and activity in the ADCC assay. At delivery of the full-term infant, the cord hemoglobin was 13.5 g per dL and the direct antiglobulin test was positive (3+) with anti-IgG. The infant did not require transfusion. A sample taken 9 weeks after delivery showed 44 percent lysis in the ADCC assay. The anti-Sc1 titer was 32, score 65. 相似文献
