OBJECTIVE: Using data collected for one series during 1987-1989 and data collected for another series during 1996, we sought to compare the frequency of and positive predictive value for carcinoma of the breast in nonpalpable, probably benign lesions that had been detected on and followed up with mammography. MATERIALS AND METHODS: During 1996, mammography was performed in 18,435 women of whom 544 (3.0%) had lesions assigned to Breast Imaging Reporting and Data System (BI-RADS) category 3 for nonpalpable, probably benign lesions. The lesions in the women were assessed as BI-RADS category 3 after the patients had undergone a diagnostic study that included additional imaging, sonography, and a focused physical examination. Patients with BI-RADS category 3 lesions were recommended for mammographic surveillance. A minimum of 2 years of follow-up data was available for 511 patients, our study population. We compared the findings for our study population with those of the previous study. RESULTS: Ninety-seven percent of the follow-up mammograms showed stability or regression of the BI-RADS category 3 lesions. Fourteen patients (3%) had nonpalpable interval progression revealed on mammography and underwent biopsy. The breast cancer detection rate in category 3 lesions among the study population was 0.4% (2/511), which was 14% of the patients who had undergone biopsies because of interval progression of the lesions. The pathologic stage of the cancers in these two patients was T1b N0. CONCLUSION: Compared with the findings from the 1987-1989 study, the frequency of BI-RADS category 3 lesions has remained stable; patient compliance for follow-up has increased; and the positive predictive value of category 3 lesions for cancer has decreased from 1.7% to 0.4% (p = 0.04). 相似文献

Antiphospholipid syndrome is accepted as one of the most important causes of hypercoagulable states. Thrombotic events in patients with antiphospholipid syndrome, predominantly women, occur at a younger age than in those suffering from atherosclerotic disease. The majority of the thrombotic events affect the deep venous system of the lower limbs and arterial thrombosis predominates in the cerebral territory. The use of anticoagulant therapy prevents recurrent thrombosis but the duration and intensity of treatment remain controversial. Aortic disease is an anecdotal fact in the literature. A case of infrarenal aortic occlusion involving both iliac arteries associated with primary antiphospholipid syndrome is presented. 相似文献

BACKGROUND: This study was undertaken in order to identify the prevalence and factors associated with depression in a group of patients with type 2 diabetes mellitus. METHODS: Our design consisted of a cross-sectional study at the Department of Neurology and Psychiatry of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán in Mexico City. Study units included 189 patients with type 2 diabetes mellitus (DM). Beck Depression Inventory scale was used to measure the presence of depression, while the independent variables evaluated to explain depression were sociodemographic (gender, marital status, religion, education, occupation, socioeconomic status) and characteristics of the disease were disease duration, comorbidity, compliance, and glycemic control. RESULTS: Prevalence of depression was 39% (74 patients). The following risk factors were identified by univariate analysis: being widowed (OR 3.54, confidence interval [CI] 1.56-8.11, p = 0.0007); female (OR 2.95, CI 1.50-5.82, p = 0.006); housewife (OR 2.08, CI 1.10-3.94, p = 0.01); poor compliance (OR 2.14, CI 1.12-4.10, p = 0.01), and presence of comorbidity (OR 5.60, CI 1.51-24.5, p = 0.002). On the other hand, the most constant associations were presence of blood glucose at the last appointment >or=200 (OR 3.23, CI 1.59-6.60, p = 0.0003) and >or=250 (OR 2.15, CI 0.93-5.03, p = 0.05), as the average of the last five blood glucoses >or=200 (OR 3.67, CI 1.76-7.73, p = 0.0001), >or=250 (OR 4.07, CI 1.61-10.49, p = 0.0007) and >or=300 (OR 2.12, CI 1.48-3.02, p = 0.003). Discriminant function analysis of the variables, previously studied in univariate analysis, was carried out for the presence of depression. A stepwise model included the following variables: average of the last five blood glucoses; 2) widowed or divorced, and 3) female. CONCLUSIONS: Frequency of depression in patients with type 2 DM was high (39%). High level of blood glucose stands out as a variable associated with presence of depression. Other associations were presence of comorbidity, being a female, and being widowed or divorced. 相似文献

Traditional asthma education has been found to be time-consuming and limited in terms of availability. Our goal was to improve asthma care by meeting special needs of children with asthma and by building on their skills in using new technologies. Multimedia asthma education occurred through the viewing of short, animated vignettes on an exam room computer. Evaluation of 228 children showed significant improvement in days of asthma symptoms (p ??.01), in emergency room visits (p ??.05), in school days missed (p ??.05), and in days of activity limitation from baseline to the year-end follow-up (p ??.05). Effective multimedia education, if integrated into pediatric practice to supplement existing asthma care, can improve clinical outcomes. 相似文献

Health-related fitness assessment in childhood and adolescence: a European approach based on the AVENA, EYHS and HELENA studies 总被引:1,自引:0,他引:1

Results from cross-sectional and longitudinal studies such as Alimentación y Valoración del Estado Nutricional en Adolescentes: Food and Assessment of the Nutritional Status of Spanish Adolescents (AVENA) and the European Youth Heart Study (EYHS) respectively, highlight physical fitness as a key health marker in childhood and adolescence. Moderate and vigourous levels of physical activity stimulate functional adaptation of all tissues and organs in the body (i.e. improve fitness), thereby also making them less vulnerable to lifestyle-related degenerative and chronic diseases. To identify children and adolescents at risk for these major public health diseases and to be able to evaluate the effects of alternative intervention strategies in European countries and internationally, comparable testing methodology across Europe has to be developed, tested, agreed upon and included in the health monitoring systems currently under development by the European Commission (EC): the Directorate General for Health and Consumer Affairs (DG SANCO); the Statistical Office of the European Communities (EUROSTAT), etc. The Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study group plans, among other things, to describe the health-related fitness of adolescents in a number of European countries. Experiences from AVENA and EYHS will be taken advantage of. This review summarises results and experiences from the developmental work so far and suggests a set of health-related fitness tests for possible use in future health information systems.On behalf of the HELENA Study Group 相似文献

The European Youth Heart Study (EYHS) addresses cardiovascular disease risk factors and their determinants in European children and adolescents. The Swedish part of the study began with cross-sectional data collection in 9- and 15-year-old schoolchildren in 1998–1999 (EYHS-I). Repeated observations of the key indicators were performed in 2004–2005 (EYHS-II). The purpose of this study was to assess potential dropout effects in EYHS-II. Participants in both EYHS-I and EYHS-II (n=459) were compared with dropouts who participated only in the EYHS-I (n=678) in relation to baseline physical activity, cardiorespiratory fitness and socioeconomic and anthropometric characteristics. Bivariate comparisons were performed using chi-square tests and gamma tests for nominal and ordinal data, respectively. Continuous data were compared by t tests and Mann−Whitney tests depending on the distribution. The Bonferroni correction was used to control for multiple hypothesis testing. Multiple logistic regression with backward elimination of variables was applied to study independent effects of variables on the probability of becoming a dropout. Analyses were performed separately for the younger and older age groups. The dropout proportion in EYHS-II was 60%. Subjects from the older age group were less likely to participate in the follow-up study (32% vs. 50%, p<0.001). In bivariate analyses, only maternal education was associated with dropout rates in the younger age group after Bonferroni correction. Males were more likely to drop out in both younger [odds ratio (OR)=1.72; 95% confidence interval (CI): 1.10, 2.96] and older (OR=1.96; 95% CI: 1.09, 3.54) age groups while basic maternal education was associated with outcome only in the younger group (OR=4.31; 95% CI: 1.78, 2.95) in regression analysis. The Swedish EYHS-II had high dropout rate after EYHS-I, but the dropouts did not differ from the participants in relation to physical activity, physical fitness, and anthropometric indices. Males were more likely to drop out than were females in both age groups. Differential dropout in relation to maternal education was observed in the younger age group. 相似文献
