Screening for diabetes in women with polycystic ovary syndrome
This study by Gagnon and Baillargeon indicates that, in women with polycystic ovary syndrome, the fasting glucose test is insufficiently sensitive to detect abnormal glucose tolerance. In an accompanying commentary, Lau details the relation of this syndrome to impaired glucose tolerance and diabetes, and the costs and other practicalities of glucose testing.
Ovarian cancer risk and health care use
Abenhaim and colleagues investigate the frequency of medical visits and pelvic examinations and the type of health care provider most often visited among women with and without ovarian cancer. They found that women who had no medical visits, pelvic examinations or regular health care provider were at increased risk of ovarian cancer. In a related commentary, Fung-Kee-Fung and colleagues discuss the implications of this finding for policy and practice.
Contraception in Canada
Fisher and Black provide information on current trends in Canadians' choices of contraception. They review the characteristics and effectiveness of contraceptive methods, with an emphasis on hormonal methods and newer options such as the levonorgestrel-releasing intrauterine device. They also discuss adherence to contraception and approaches to counselling to promote adherence and to reduce the risk of sexually transmitted infection in the context of contraception.
