Estrogen replacement therapy among elderly women: results from the 1995 medicare current beneficiary survey

Research Objectives: To develop population-based estimates of estrogen replacement therapy use rates in 1995 among women over age 65 living in the community; to estimate the impact of socioeconomic and health characteristics on estrogen use. Method: Estimates are based on a large, nationally representative sample of Medicare beneficiaries; detailed self-report data were merged with Medicare claims. Results: Overall, 13.1% of women reported use of estrogen replacement therapy in 1995. Estrogen users were more likely to be white, age 65–74, with private insurance, high income, history of osteoporosis and heart problems, no history of breast cancer, and a patient of gynecologists. Conclusions: Estrogen use was substantially lower among the socioeconomically disadvantaged, controlling for medical history variables, suggesting considerable inequity in access to estrogen replacement therapy treatment.     

Back to the future for wound care?

The European Renaissance was a time of enormous change and rapid progress in the arts, sciences, and medicine. A glimpse of wound care in the last phase of the European Renaissance is provided by the analysis of work by Wilhelm Fabry, the "father of German surgery," as provided in his book De Combustionibus ("Burns") which details his range of treatments for the burn wound, as well as his approach to the later problems of scarring and contracture. We describe some of the historic events which may have stimulated Fabry's writings, in particular, the influences passed down from the medical school of Padua which thereby advanced the cause of wound care and surgery. Finally, we briefly explore the potential of such an approach to the works of our medical forefathers.     

Reading, Demographic, Social and Psychological Factors Related to Pre-adolescent Smoking and Non-smoking Behaviors and Attitudes

The purpose of this study was to examine reading, demographic, social and psychological factors related to pre-adolescent smoking and non-smoking behaviors and attitudes. The school-home humanistic education program was implemented in a large, urban public school system. It stressed responsible decision-making, increased self-esteem and the inter-relationships among the acquisition of knowledge of the consequences of smoking, personal feelings, family relationships and behavior. The results showed that family involvement was necessary to affect smoking attitudes and behaviors. Of all the variables studied, reading had a most pervasive relationship. Peer influence and self-esteem also were related to smoking knowledge, smoking attitude, future smoking intentions and the "purchase" of cigarettes. Two of several conclusions drawn from the results are: 1. Family involvement is necessary to affect attitudes and behaviors. 2. Health education research that does not investigate the relationship between program outcomes and reading achievement may be misleading.

膀胱移行细胞癌微卫星不稳定性及其机制的研究

目的　探讨膀胱移行细胞癌 (BTCC)染色体微卫星不稳定性的表现及与基因突变的关系。方法　采用聚合酶链反应 (PCR)方法检测 4 0例 BTCC患者 5个微卫星位点的改变 ,同时用同样的方法检测癌组织中BAX基因和转化生长因子 (TGF) - β 型受体基因移码突变的情况。结果　至少发生一个微卫星位点改变的阳性率为 82 % (33/ 4 0 ) ,D9S16 2、D16 S4 76、D9S5 4、FGA和干扰素 (IFN) - A1位点改变各自的阳性率分别为 5 8%(2 3/ 4 0 )、 4 2 % (17/ 4 0 )、 38% (15 / 4 0 )、 4 8% (19/ 4 0 )和 5 5 % (2 2 / 4 0 ) ,阳性检出率与良性病变差异有显著性 ,与肿瘤的分期分级无显著相关性。发生微卫星改变的 33例中 ,33% (11/ 33)和 4 2 % (14 / 33)分别可见 TGF- β 型受体基因和 BAX基因的移码突变。结论　检测染色体微卫星的改变是 BTCC早期诊断、监测复发的有效手段 ,染色体微卫星改变可能是 BTCC发生过程中多基因突变的一种表现形式
