Nonexperimental evaluation of the effectiveness of a screening program for lung cancer.

The effectiveness of screening to control lung cancer was examined in the German Democratic Republic by analyzing data from a cancer registry and incidence and mortality rates for lung cancer relative to different screening policies, and by two case-control studies. Mortality from lung cancer did not appear to be affected by the screening programs studied. The high cost of mass screening, combined with uncertainty about the benefits of early treatment of lung cancer, outweigh the vague advantages of such screening.     

What Factors in Early Pregnancy Indicate that the Mother Will Be Hit by Her Partner during the Year after Childbirth?A Nationwide Swedish Survey

Abstract: Background : To be hit by one's intimate partner during the first year after childbirth may affect a woman's health and ability to take care of her newborn. The purpose of this study was to document the prevalence and indicators in early pregnancy of a woman being hit by her partner during the year after childbirth. Method : Information was collected by a postal questionnaire in early pregnancy and 12 months after childbirth from the approximately 5,550 women in Sweden who visited an antenatal care clinic for the first time during one of three chosen weeks in 1999 and 2000. Results : Of the 3,266 recruited women, 2,563 returned the follow‐up questionnaire. Being hit during the first year after childbirth was reported by 52 of the 2,563 (2%) women: 32 (61%) had been hit by their partner once, 12 (23%) twice, and 8 (15%) three or more times. Risk increased in women who were age 24 years or younger (3.9% had been hit), unmarried (7.1%), born in countries outside Europe (6.8%), with a partner born outside Europe (5.4%), had a low level of education (8.9%), and were unemployed (5.0%). In early pregnancy, women with back pain (4.0%), a chronic illness (4.1%), coital pain (6.1%), frequent depression‐related symptoms (8.1%), stomach pain (3.8%), or a urinary tract problem (6.3%) were hit more often than others after childbirth. Conclusions : At least 2 percent of Swedish women giving birth in 2000 were hit by their partner during the year after childbirth. Using identified predictors during antenatal care may increase the likelihood of finding women at risk, thereby enhancing the possibility of interventions to prevent this crime and health hazard.     

Hypertension secondary to progressive vascular neurofibromatosis

A 4 year old girl with neurofibromatosis type 1 (NF1) was referred for hypertension. An aortogram showed narrowing of the left main renal artery. An angiogram three and a half years later showed coarctation of the abdominal aorta. She underwent aortoplasty but the stenosis recurred. Vascular involvement in NF1 may be progressive and requires long term follow up.     

THE MULTIPLICATION OF FIBROBLASTS IN VITRO

1. It may be concluded that, under the conditions of the experiments and within the limits of accuracy of the method, the temporary multiplication of fibroblasts cultivated in the plasma of an adult animal is not due to the serum. It may be attributed to the presence of a small amount of embryonic juice within the tissue itself. 2. The indefinite multiplication of fibroblasts in a medium composed of adult plasma and of embryonic juice is due neither to the serum nor to the fibrin. It depends entirely on substances contained in the embryonic juice. 3. There is a definite relation between the rate of growth and the concentration of the embryonic juice in the medium.     

海南省性罪错妇女11年性病感染情况调查分析

目的 通过对11年来性罪错人员性病感染情况的调查分析,掌握性病在性罪错妇女中流行的特点,为政府部门对性病防治政策的制定提供科学依据。方法 对1990年元月至2000年12月海南省妇女收容教育所被收教的性罪错妇女进行性病检查,统计其各种性病的发病人数,然后进行分析。结果 11年中共收教4780人,其中感染淋病、非淋菌性尿道炎(宫颈炎)、尖锐湿疣、梅毒、生殖器疱疹、HIV共2967例,阳性率为62．07％,其中非淋菌性尿道炎(宫颈炎)1826例(38．20％)、淋病469例(9、81％)、梅毒414例(8．7％)、尖锐湿疣246例(5．14％)、生殖器疱疹11例(0．23％)、HIV阳性1例(0．02%)。结论 性罪错妇女六种性病的患病率很高,达62．07％,其中非淋菌性尿道炎(宫颈炎)为其主要病种,淋病的患病率逐年下降,梅毒的患病率逐年上升,尖锐湿疣基本稳定,其流行特点值得我们重视。     

甲状腺机能亢进症危险因素病例对照研究

目的 探讨各危险因素与甲亢的关系。方法 对三亚地区110例甲亢采用1：2配比的病例对照研究,资料处理采用条件Logistic回归分析.结果 甲亢发病与下列5因素关系密切：家庭年收入(OR=2．055)、食用碘盐(OR=2．133)、喜食海产品(OR=2．183)、感染(OR=2．382)、家庭生活事件(OR=3．017) 结论 家庭生活事件、感染、喜食海产品、食用碘盐、家庭年收入增高等是甲亢的危险因素。
