Ovarian cancer has the highest case fatality rate among gynaecological cancers worldwide because of lack of effective screening methods and non-specific early warning symptoms with late presentation. A reinvigorated study is necessary in the developing countries because of a projected increase in its incidence. The decreasing fertility rate and increasing use of ovulation induction drugs are some of the reasons. The Ovarian Cancer Service of the Department of Obstetrics and Gynaecology, University College Hospital, Ibadan, Oyo State, Nigeria commenced the first longitudinal study of this malignancy from 1 December 1998 in order to establish a regional management and research centre. It is a questionnaire survey detailing the demography, clinical and staging laparotomy findings and histology of all confirmed cases. Twenty-one staging laparotomy and histologically confirmed ovarian cancer cases were managed from 1 December 1998 to 31 July 2002, about 1.5% of the 1387 gynaecological admissions. It is the third most common of the gynaecological cancers, representing 9.8% of the 214 cases. More than 60% of the patients were 50 years or younger. Only 19% were nulliparous, with 47.6% having had five or more deliveries. Only two patients (9.5%) had used the oral contraceptive pill, for a maximum period of 1 month. Only one patient (4.8%) had a positive family history of cancer. Abdominal swelling was the most common presenting symptom. Eighty-one per cent of the patients presented in Stages III and IV. Epithelial ovarian cancer constituted about 76.2% of the cases. Only 23.8% had adjuvant therapy, consisting of combination chemotherapy using cisplatin-based regimes. The case fatality rate 6 months after surgery was 76%. The ovarian cancer patients in this environment are younger and of higher parity than expected. The risk factors for this disease require further study.

The aim of this study was to evaluate the expression of activin: beta A and beta B subunit and follistatin in endometrium of women with implantation failure (n = 10) and compare it with a fertile control group (n = 7). Immunohistochemical staining intensity for follistatin in the endometrial glandular epithelium from women with implantation failure were significantly lower than that in control women (P = 0.03). The decreased expression of follistatin in epithelial cells in the endometrium of women with implantation failure after in vitro fertilisation (IVF) may suggest that follistatin may play a role in the implantation process.Keywords Endometrium, implantation, inhibin follistatin, IVF.Please cite this paper as: Prakash A, Tuckerman E, Laird S, Ola B, Li T, Ledger W.

Clinicians ignore lengthy guidelines and prefer pocket cards and concise pamphlets. However, brevity in guidelines may lead to deficiency in quality. Our objective, therefore, was to examine the quality of brief guidelines produced by professional bodies, using those produced by the UK Royal College of Obstetricians and Gynaecologists (RCOG) as an example. We assessed all 22 'green-top' guidelines, produced by September 2002, for quality using a validated 37-item appraisal instrument. This instrument evaluated the guidelines on three dimensions, namely rigour of development, context and content and applicability. Ten (45%), 18 (82%) and five (23%) of the 22 guidelines met at least half the quality criteria for rigour of development, context and content and applicability, respectively. We conclude that the brief guidelines were deficient in several specific quality items, particularly those in the applicability dimension. Guideline developers need to achieve the higher quality standards expected of professional bodies.
