PURPOSE: Chest radiographs (CXR) are the standard method for evaluating rib fractures in abused infants. Computed tomography (CT) is a sensitive method to detect rib fractures. The purpose of this study was to compare CT and CXR in the evaluation of rib fractures in abused infants. METHODS: This retrospective study included all 12 abused infants identified from 1999 to 2004 who had rib fractures and both CXR and CT (8 abdomen CTs, 4 chest CTs). CT exams had been performed for clinical indications, and were obtained within one day of the CXR. Studies were reviewed by two pediatric radiologists to determine the number, locations, and approximate ages of the rib fractures. A total of 225 ribs were completely (192) or partially (33) seen by CT, and the matched ribs on CXR were used for the analysis. RESULTS: The mean patient age was 2.5 months (1.2-5.6), with seven females and five males. While 131 fractures were visualized by CT, only 79 were seen by CXR (p<.001). One patient had fractures only seen by CT. There were significantly (p<.05) more early subacute (24 vs. 4), subacute (47 vs. 26), and old fractures (4 vs. 0) seen by CT than by CXR. Anterior (42 vs. 11), anterolateral (21 vs. 12), posterolateral (9 vs. 3) and posterior (39 vs. 24) fractures were better seen by CT than by CXR (p<.01). Bilateral fractures were detected more often by CT (11) than by CXR (6). CONCLUSIONS: While this study group is small, these findings suggest that CT is better than CXR in visualizing rib fractures in abused infants. 相似文献

This study addresses the health of young children and how to safely and effectively care for children with diarrhea in the home and in early child care settings. A baseline survey showed the prevalence of oral rehydration solution (ORS) usage at last diarrhea bout to be low. An educational workshop was developed to train parents and child care professionals on how to properly manage young children with diarrhea and reduce the risk of diarrhea spread at home and in early childhood settings. Specific intervention activities are discussed and program activities, including specially designed materials for mixing homemade ORS are described. A comparison of pre- and postintervention data indicates substantial gains in knowledge among both urban and rural populations. Implications of research findings are discussed along with suggestions for future research. 相似文献

ABSTRACTResearch on teacher education, especially on the development of teacher educators, is limited. This paper considers the role of dispositions in the development of pedagogical knowledge (PK) for science teacher educators (STEs), across stages of career. It argues that beliefs and perceptions shift and change along with, but not directly related to, what STEs pay attention to and when they pay attention to it. The eight participants were asked to identify the critical experiences (CEs) of their career that impacted on their development of PK. CEs were analyzed using Morine-Dershimer and Kent’s (1999) model of PK as a framework, but also to identify common emergent themes across participants and common emergent themes for individuals that led to identification of patterns of actions and finally, participant’s dispositions. The notion that beliefs, dispositions and PK are all developed for each individual at their own pace and in their own way is reinforced. 相似文献

This study examined the utility of cooperative groups as a technology for mainstreaming academically deficit students in a regular fourth grade classroom. Twenty‐seven students (mean age 8.6 years), including five targeted special needs learners, took a weekly spelling test of 20 words chosen from the fourth grade reader. A return to baseline research design indicated that cooperative groups promoted higher academic mastery among those with special needs and regular education learners when compared with two types of individualistic techniques. Results support the use of cooperative groups as a technique for academic as well as social mainstreaming in the regular classroom. 相似文献

The request to evaluate a nontraditional degree program sounds simple enough. But what does it mean “to evaluate the program?” This article identifies twelve major areas seeming to require evaluative attention according to the perspectives of a number of different groups of people. In addition to identifying these areas, the study suggested priorities for the areas in terms of their long-term, overall importance in a complete evaluation plan and their immediate or short-term importance in the early stages of program implementation. 相似文献
