    OBJECTIVE: To compare the effectiveness of the Vabra aspirator and the Pipelle device as an outpatient endometrial assessment tool.
    METHOD: This was a randomised, prospective trial conducted for a period of one year.
    RESULTS: A total of 147 patients were recruited, of which 71 were in the Vabra group and 76 were in the Pipelle arm. The procedure success rate in the Pipelle group was significantly higher than the Vabra arm (98.7 vs 88.7%, P=0.02). Adequate tissue yield was also significantly more in the Pipelle arm (73.3 vs 52.4%, P=0.02). Cost-benefit analysis revealed a higher average cost per patient in the Vabra group compared to the Pipelle arm.
    CONCLUSION: This study proved that the Vabra aspirator was not as effective as the Pipelle device in obtaining endometrial tissue for histological diagnosis. Despite its higher price per unit, the Pipelle device was a more cost-effective tool for outpatient endometrial assessment.

    The best method of screening for gestational diabetes (GDM) remains unsettled. The 50-g glucose challenge test (GCT) is used in a two-stage screening process but its best threshold value can vary according to population.

    We studied 253 women with a pregnancy complicated by a birth defect and 506 controls to determine the frequency and type of prenatal tests and the types of defects detected antenatally. Most women had at least one ultrasound examination, but the frequency of other screening tests was low. Only 38 (15%) of defects were detected antenatally (37 by ultrasound). Birth prevalence is unlikely to be affected by pregnancy termination.

    In a retrospective analysis of 192 cases of presumed hyperemesis gravidarum, there were no biochemical markers that predicted hospital readmission. There was, however, statistically significant negative predictive value in abnormal liver function tests. This could represent acute self-limited illness with a component of hepatitis as the cause for the clinical presentation, rather than hyperemesis.

    Rectocele is a herniation of the anterior wall of the rectal ampulla through a defect in the rectovaginal septum causing protrusion of the posterior vaginal wall. Common symptoms include symptoms of prolapse and obstructed defecation.

    OBJECTIVES: The objectives of this study were to investigate the prevalence of factor V Leiden mutation in Malay women with recurrent spontaneous abortion and to clarify the contribution of the factor V Leiden mutation to recurrent miscarriages in these women.

    DESIGN: A prospective case control study between June 1999 and April 2000.

    SETTING: Hospital University Science of Malaysia, Kubang Kerian, Kelantan, and Maternal and Child Health Clinic, Pasir Mas, Kelantan, Malaysia.

    SAMPLES: A total of 46 Malay women with a history of three or more first or second trimester miscarriages were studied. The control group consisted of 46 parous women without obstetric complications.

    METHODS: Diagnosis of factor V Leiden mutation was made by examination of factor V Leiden allele product following Mnl I digestion of factor V Leiden alleles amplified by polymerase chain reaction.

    RESULTS: None of the 46 women with recurrent spontaneous abortion carried the mutation. Also, we found no subject carrying the factor V Leiden alleles in the control group.

    CONCLUSION: These results suggest that that there is no association between the factor V Leiden mutation and recurrent spontaneous abortion in the Malay population.

    This is a rare case of antepartum haemorrhage arising from the nonpregnant uterus in a woman with uterine didelphys. The bleeding and subsequent passage of a decidual cast did not have any adverse effect on the ongoing pregnancy.

    Misoprostol seems to be a drug with many potential uses apart from the treatment of gastric and duodenal ulcers. The oral tablet appears to be effective for termination of midtrimester pregnancy when administered intravaginally. Further research should be carried out to determine its full range of action in order that the drug can be utilized to its maximum potential.

    Transvaginal sonography was performed in 70 patients diagnosed to have placenta praevia by transabdominal sonography. The diagnosis was confirmed either by digital examination in theatre at term or operative finding at delivery. Forty-nine cases (70%) were correctly diagnosed to have placenta praevia by both modes of sonography. Transvaginal sonography ruled out placenta praevia in 12 cases (17%) thought to be placenta praevia by transabdominal ultrasound. Both transabdominal and transvaginal sonography demonstrated 'placental migration' in 4 cases (6%) which were no longer praevia at delivery. Five patients (7%) were erroneously believed to have placenta praevia by both sonographic techniques. Overall, the diagnostic accuracy of transvaginal sonography was 92.8% compared with 75.7% for transabdominal sonography. None of the subjects experienced any exacerbation of bleeding or other complications. The results suggest that transvaginal sonographic localization of the placenta is safe and superior to the transabdominal route.

    This prospective, randomized study compared the efficacy of intravaginal misoprostol (Cytotec) and gemeprost (Cervagem) as an abortifacient for intrauterine deaths in second trimester pregnancy. Side-effects, complications and the cost-effectiveness associated with each drug were assessed. 21 out of 25 patients (84%) in the misoprostol group aborted whereas only 17 out of 25 patients (68%) in the gemeprost group aborted within 24 hours after the initiation of therapy. In the misoprostol group, the abortion rate was influenced by the gestational age with 100% abortion rate for those > 17 weeks' gestation compared to 67% for those with a gestational age of 13-16 weeks. Side-effects were rare in either group and no major complications were reported in either group. Misoprostol was definitely more cost-effective compared to gemeprost as the mean cost of inducing an abortion using misoprostol was RM 1.08 whereas that of gemeprost was RM 105. We thus concluded that misoprostol was at least as effective as gemeprost as an abortifacient for intrauterine death in second trimester pregnancy. Moreover, it was less costly, with very few side-effects.

    The sales data of oestrogen replacement products for 8 developing countries from 1993 to 1995 were analyzed. The data from Malaysia, Pakistan, Taiwan, Thailand, Indonesia, Philippines and South Korea showed the increasing use of oestrogen replacement products. The total usage however varied widely, from only US$11,153 (Philippines in 1993) to as much as US$6,306,717 (Taiwan in 1995). In Singapore, where oestrogen replacement is an accepted and established form of therapy for the postmenopausal woman, there has been an increase in the usage of the nonoestrogen replacement products. There are multiple reasons for the increasing sales of hormone replacement products in the developing countries and these are explored in this article. In some of the developing countries, for example China and India, hormone replacement therapy has just been introduced. However, in those developing countries in which hormone replacement therapy is already available, sales figures show increasing usage. The future augurs well for hormone replacement therapy.

    This case represents a unique primary ovarian tumour consisting of malignant mucinous elements and granulosa-theca-cell elements, the histogenesis of which remains uncertain. It also underscores the need for thorough sampling of mucinous tumours in order to discover a possible coexisting, different neoplastic component.
