Oestrogens and Alzheimer's disease

In the last decade, several reports suggest that oestrogen replacement therapy (ORT=ERT=estrogen replacement therapy) might prevent or delay Alzheimer's disease. Oestrogens influence and modulate brain structure and brain function. There are substantial arguments that the postmenopausal oestrogen loss might, together with other factors, accelerate the appearance of Alzheimer's disease. The evidence is suggestive, but not compelling, that ORT can reduce the relative risk to suffer from Alzheimer's disease. Furthermore, recent findings are consistent with the hypothesis that oestrogens might ameliorate the symptomatology in early stages of Alzheimer's disease. However, it has to be remembered that in most clinical trials the number of oestrogen users was quite small, and, usually, oestrogen use was not randomised. The aim of the present review is to discuss the data available today in view of their clinical relevance.     

Hormonal contraception for adolescents

The new hormonal contraceptives are safe, effective and with fewer side effects than the older formulations. Their incidence of serious complications is low, particularly as compared to the health risk related to pregnancy. Adolescents must be screened for contra-indications before giving them a hormonal contraceptive. Because pills do not prevent sexually transmitted diseases, teenagers should be counselled to use a barrier methods together with COCs. Young girls need frequent follow-up and close monitoring to minimise side effects and to increase compliance and continuation in use. Long-term contraception by implants represents a valid alternative option with an increasing popularity among adolescents.
