International League of Associations for Rheumatology classification of juvenile idiopathic arthritis: second revision, Edmonton, 2001.

Abstract: The primary aim of the International League of Associations for Rheumatology (ILAR) proposals for classification of juvenile idiopathic arthritis (JIA) is to delineate, for research purposes, relatively homogeneous, mutually exclusive categories of idiopathic childhood arthritis based on predominant clinical and laboratory features. As part of a continuing review process, the ILAR Taskforce on Classification of Childhood Arthritis met in Edmonton in 2001 to discuss modifications to the proposed JIA classification. Since the publication of the first revision of the original classification 1 , a number of descriptive studies using the new classification have been reported 2-11. The aims of this communication are 2-fold: to outline modifications to the revised classification proposed as a result of the Edmonton meeting, and to correct misconceptions highlighted by the published studies concerning the clinical use of the classification. The Edmonton Revision The changes embodied in the second revision of the classification are as follows: 1. Clarification of the definitions of each category. 2. Improvement in the congruity between inclusion and exclusion criteria. 3. Removal of the requirement that a dermatologist make the diagnosis of psoriasis. 4. Removal of the requirement that there be medical confirmation of HLA-B27 associated disease in a relative. 5. Reduction in the age for criterion " 3 " of enthesitis related arthritis, and exclusion " b " from 8 years to 6 years of age. 6. Improvement in the consistency of the structure. The impracticality of the requirement that a diagnosis of psoriasis be made by a dermatologist was recognized, and this requirement was modified so that the diagnosis of psori-asis could be made by a physician (not necessarily a dermatologist). Similarly, it is no longer required that there be medical confirmation of an HLA-B27 associated disease in a relative as contained in exclusion " c. " It is evident that it is very difficult to obtain a reliable history of psoriasis or an HLA-B27 associated disease in a second-degree relative. Therefore, a history of importance to the application of the criteria is restricted to the patient or a first-degree relative (parents or siblings) only. The study of Murray, et al 8 indicated that the HLA-B27 association is important in boys over the age of 6 years at onset of arthritis, and this age was substituted for 8 years in exclusion " b. " Discrepancies between inclusion and exclusion criteria were resolved, and the exclusions were identified by the letters …

Multistate point-prevalence survey of health care-associated infections.

Abstract: Background Currently, no single U.S. surveillance system can provide estimates of the burden of all types of health care–associated infections across acute care patient populations. We conducted a prevalence survey in 10 geographically diverse states to determine the prevalence of health care–associated infections in acute care hospitals and generate updated estimates of the national burden of such infections. Methods We defined health care–associated infections with the use of National Healthcare Safety Network criteria. One-day surveys of randomly selected inpatients were performed in participating hospitals. Hospital personnel collected demographic and limited clinical data. Trained data collectors reviewed medical records retrospectively to identify health care–associated infections active at the time of the survey. Survey data and 2010 Nationwide Inpatient Sample data, stratified according to patient age and length of hospital stay, were used to estimate the total numbers of health care–associated in...

Perceived locus of causality and internalization: Examining reasons for acting in two domains.

Abstract: Theories of internalization typically suggest that self-perceptions of the "causes" of (i.e. reasons for) behavior are differentiated along a continuum of autonomy that contains identifiable gradations. A model of perceived locus of causality (PLOC) is developed, using children's self-reported reasons for acting. In Project 1, external, introjected, identified, and intrinsic types of reasons for achievement-related behaviors are shown to conform to a simplex-like (ordered correlation) structure in four samples. These reason categories are then related to existing measures of PLOC and to motivation. A second project examines 3 reason categories (external, introject, and identification) within the domain of prosocial behavior. Relations with measures of empathy, moral judgement and positive interpersonal relatedness are presented. Finally, the proposed model and conceptualization of PLOC are discussed with regard to intrapersonal versus interpersonal perception, internalization, cause-reason distinctions, and the significance of perceived autonomy in human behavior.
