Paraffin-embedded sections of vulvar squamous-cell carcinomas and of normal vulvar tissues were examined for HPV types 6, 11, 16, 18 and 33 by the polymerase chain reaction. Overall, 19 of 62 tumours harboured HPV DNA of types 16, 18 or 33. HPV types 6 and 11 were not detected. HPV DNA was found in 61% of tumours with adjacent intraepithelial neoplasia (VIN III), and in 13% of tumours without associated VIN III. HPV DNA was not detected in any of 101 normal vulvar tissues. HPV DNA was found more often in younger women, in patients with VIN III-associated tumours, and in those with multicentric anogenital neoplasia. This points to the existence of a subset of vulvar carcinomas preceded by intraepithelial neoplasia, with HPV as a major factor in carcinogenesis. HPV also seems to be an important factor in the development of multiprimaries in these patients. The 2 groups of patients with vulvar carcinoma did not differ with regard to prognosis, as estimated by the risk of recurrence after primary surgery. 相似文献

BackgroundMammographic density adversely affects diagnostic accuracy and may be a risk factor for breast cancer. Mammographic density is affected by hormone replacement therapy (HRT).
ObjectiveTo assess mammographic density in postmenopausal women with and without HRT.
MethodPart I. Mammographic density was determined in 1232 postmenopausal women attending a breast screening clinic. Density was compared between HRT users and nonusers in three age groups. When available, previous mammograms were assessed for interval density change. Part II. Density change in 162 women during transition from premenopause to postmenopause was recorded. HRT effect was assessed.
ResultsPart I. There was no density difference between postmenopausal HRT-users and nonusers younger than age 55. Thereafter, the density was significantly less in nonusers. In the majority of HRT-users the density remained at pretreatment levels but density increased in 8% of women after HRT was started. Part II. Of 117 HRT nonusers followed over menopause 38% had a density decrease before age 55. Of those started on HRT, 80% had no density change, 18% decreased density and 2% increased density.
ConclusionsThe density decreases significantly after age 55 with the greatest change occurring between age 55 and 64. This decrease does not occur in the majority of HRT-users. Usually HRT maintains the density present at the time HRT is started. Density decreases after HRT is started in some women suggesting refractoriness to hormones. In fewer than 8% of women density increases commensurate with HRT. Any adverse effect of HRT may depend on the receptivity of the epithelial elements which, in turn, may be reflected by the mammographic density at the time HRT is started. 相似文献

Iron deficiency anaemia (IDA) has a large impact on productivity, mental performance, child growth, immunity and pregnancy outcome. In Indonesia, 50 to 70 million people (25–30% of the population) suffer from IDA. In 1995, the prevalence among pregnant women, underfives and female workers was 50.9%, 40.5% and 30%, respectively. Because nutrition and health are essential to human development, Indonesia has identified their improvement, including reducing IDA, a high priority. Several programs are implemented to control IDA. Iron supplementation for pregnant women started in 1974 and currently provides 60% with 90 tablets. Because infants and children cannot meet their iron requirements through diet alone, unless it contains fortified foods, distribution of iron-rich syrup to underfives was started in less developed villages in eastern Indonesia in 1996. Since 1996, factories should supplement their female workers with iron supplements once per week, 16 weeks per year, in order to increase their well-being and productivity. Other groups, such as female adolescents, school children and non-pregnant women are currently targeted through special projects and through IEC, using dietary guidelines, directed at a larger audience. With the increase in economic growth, self-purchasing of supplements and food fortification become more viable strategies. Producers of some brands of noodles and weaning foods are currently fortifying their products, while producers of “jamu” (traditional herb drinks) are increasing the content of enhancers of iron absorption. Reducing IDA in Indonesia is the goal of the Department of Health in collaboration with other departments, non-governmental organisations, international agencies, and the private sector. 相似文献

Knowledge, perceptions, and attitudes of Hong Kong Chinese women on screening mammography and early breast cancer management 总被引:1,自引:0,他引:1
In most Western countries, screening mammography and breast-conserving therapy (BCT) are now well-established practices and have been well accepted by women over the last two decades. There are limited data on the acceptability of these strategies by Chinese women in an Oriental society where a population-based screening program has not been established and mastectomy is still commonly practiced. A survey was conducted of 1012 Hong Kong Chinese women, ages 18-69 years, to assess the level of knowledge, perceptions, and attitudes on screening mammography and the surgical management of early breast cancer. Most women (58%) had never heard of mammographic screening, and housewives were more likely to have heard of it than nonhousewives (49% versus 37%; p = 0.0001). The majority (82%) of those who had heard of mammographic screening believe that it can detect early breast cancers and reduce mortality, however, only 58% of these women would participate in yearly screening and clinical breast examination despite acknowledging the potential benefits; a lack of time and the cost were the predominant reasons given. Forty-seven percent of women had the misconception that mastectomy was the only curative treatment; when the alternative was explained, the overall rate for choosing BCT rose from 29% to 49%. There was no correlation between age and the choice of surgery. Most women (75%) felt that breast reconstruction after mastectomy was desirable and acceptable. A lack of knowledge on mammographic screening is prevalent and the concept of preventive health care has a low priority in this Chinese population. Mastectomy is still widely perceived as the only curative treatment; BCT with cosmetic reconstruction is seen as an acceptable alternative. Interventions to improve the accuracy of information and to encourage preventive health care behaviors will have a positive impact on establishing cancer screening programs and providing quality cancer care in the future. 相似文献

We conducted a community-based study of the prevalence and correlates of hepatitis B virus (HBV) infection and immunization
among young adults in a “drug supermarket” neighborhood in New York City. Four hundred eighty-nine young adults ages 18–24
years were recruited from Bushwick, Brooklyn through multistage household probability sampling (n=332) and targeted sampling
(n=157), interviewed, and tested for three hepatitis B markers (HBsAg, anti-HBc, and anti-HBs). Serological evidence of HBV
infection was found in 8.0% (6.0% in the household sample and 12.1% in the targeted sample) and of hepatitis B immunization
in 19.6% (22.6% in the household sample and 13.4% in the targeted sample). HBV infection was higher among young adults who
either used crack or injected drugs and among those who traded sex for money or drugs. Having Medicaid was significantly associated
with lower odds of infection in the household sample and higher odds of immunization in the targeted sample. Although adolescent
hepatitis B immunization has been a public health priority in the United States since 1995, nearly three-quarters of young
adults in this community did not have serological evidence of being either exposed or immunized. Whereas subsequent younger
generations benefited from universal childhood hepatitis B immunization, this particular cohort of young adults who live in
communities like Bushwick presents a unique group for prevention intervention.

In a series of 137 patients with cancer of the vulva who had undergone radical surgery we investigated, by means of a Cox regression model, which combination of clinical variables and clinical as well as histopathological variables afforded the best prediction of survival/death from cancer and survival/death from other causes. Among clinical variables the best prediction was afforded by a combination of tumor site in the clitoris/not clitoris, tumor size greater or smaller than 40 mm, obesity/not obesity, and age. Among clinical and histopathological variables the best prediction was by a combination of groin node metastases/not groin node metastases, tumor site in the clitoris/not clitoris, degree of differentiation high/moderate + low, and age. The combination of clinical and histopathological variables had a significantly better predictive power than clinical variables alone. The best prognostic group in both combinations had a 5-year-survival for cancer of 98%, while the poorest prognostic group in the two combinations showed a 5-year survival for cancer of 19 and 9%. The best predictors of death from causes other than cancer were age and a poor general health. It is concluded that the poorest prognostic group is definitely under treated and that the best prognostic group is presumably over treated. Patients in poor general health and with a good cancer prognosis should receive a more conservative treatment. 相似文献
