RESUMEN

A randomized, controlled, double-blind, double-dummy, phase III clinical trial was conducted in 84 women to compare the efficacy of a s.c. injection of 250 microg recombinant human chorionic gonadotrophin (rHCG; Ovidrel) to an i.m. injection of 5000 IU urinary HCG (uHCG; Profasi) in inducing folliculogenesis, resumption of oocyte meiosis and luteinization after ovulation induction with recombinant follicle stimulating hormone (Gonal-F). The study primary endpoint was comparison of the number of oocytes retrieved per patient receiving either compound. Secondary comparisons included the number of oocytes retrieved per follicles aspirated; the number of mature oocytes; normally fertilized oocytes; and cleaved embryos. There were no statistically significant differences between groups for the primary endpoint (mean +/- SD oocytes retrieved 10.8 +/- 4.5 for rHCG versus 10.3 +/- 5.1 for uHCG) or each of the secondary endpoints except for increased concentrations of progesterone 6-7 days after rHCG administration (353.2 +/- 215.1 versus 234.1 +/- 129.4 nmol/l; P < 0. 004) and for HCG during the luteal phase following rHCG (P < 0.02). There were also no significant side-effects for either drug. Since the confidence intervals for the difference of the number of oocytes retrieved between the two treatment groups were within the bounds defined by the multi-trial protocol equivalence between rHCG and uHCG could be declared.

RESUMEN

BACKGROUND: Women with polycystic ovaries have associated risk factors for coronary artery disease. It is unknown whether women with more extensive coronary artery disease are more likely to have polycystic ovaries. OBJECTIVE: To determine whether women who have more extensive coronary artery disease as seen on coronary angiography are more likely to have polycystic ovaries appearing on ultrasonography than are women with less severe coronary disease. DESIGN: Prevalence study of women who had had coronary angiography. SETTING: Women referred for coronary angiography for assessment of chest pain or valvular disease in Auckland, New Zealand, during a 2-year period. PATIENTS: 143 women 60 years of age or younger who had had coronary angiography. Women who had previously had bilateral oophorectomy were excluded. MEASUREMENTS: The extent of coronary artery disease assessed by quantitative angiography was compared with the presence or absence of polycystic ovaries. Pelvic ultrasonography was done without knowledge of the extent of coronary artery disease. Assessment of angiograms was blinded. Insulin resistance and gonadotropin, testosterone, and serum lipid levels were also measured. RESULTS: Polycystic ovaries were found in 42% of women and were associated with hirsutism; previous hysterectomy; higher free testosterone, triglyceride, and C-peptide levels; and lower high-density lipoprotein cholesterol levels. Women with polycystic ovaries had more extensive coronary artery disease than women with normal ovaries (number of segments with > 50% stenosis, 1.7 [95% CI, 1.1 to 2.3] compared with 0.82 [CI, 0.54 to 1.1]; P < 0.01). On logistic regression analysis, the extent of coronary artery disease (P = 0.032) and family history of heart disease (P = 0.022) were predictors of the presence of polycystic ovaries. CONCLUSIONS: In women having coronary angiography, those with more extensive coronary artery disease were more likely to have polycystic ovaries on ultrasonography than were those with less extensive disease. Visualization of polycystic ovaries by sonography was associated with distinct metabolic and endocrine abnormalities. Further study is required to evaluate whether surgery or hormone replacement therapy can modify the risk.

RESUMEN

Antiphospholipid antibodies have an established association with pregnancy complications such as recurrent miscarriage, growth retardation, placental abruption and stillbirth but their mechanism of action is unclear. We have investigated whether antiphospholipid antibodies occur more frequently in women having in-vitro fertilization (IVF) and whether their presence is associated with the likelihood of failed implantation. We studied 240 women undergoing IVF treatment who were

RESUMEN

OBJECTIVE: Polycystic ovaries have been diagnosed in more than 20% of premenopausal women using ultrasound. The aim of this study was to determine whether polycystic ovaries exist in post-menopausal women. DESIGN: Two groups of women were studied; group 1 consisted of 18 post-menopausal volunteers and group 2 comprised 142 women, 94 of whom were post-menopausal who had recently undergone coronary angiography. MEASUREMENTS: Transabdominal and transvaginal ultrasound scans were performed and measurements made of uterine area, endometrial thickness and ovarian volume. The morphological appearance of the ovaries was also noted. Fasting blood samples were taken. Medical and menstrual questionnaires were completed. RESULTS: Polycystic ovaries were found in 8/18 (44%) of group 1 and 60/142 (42%) in group 2. Polycystic ovaries were detected in 35/94 (37%) of the post-menopausal women in group 2. Post-menopausal women with polycystic ovaries had larger ovaries containing more follicles compared with post-menopausal women with normal ovaries. Post-menopausal women with polycystic ovaries had higher serum concentrations of testosterone and triglycerides than had post-menopausal women with normal ovaries. CONCLUSIONS: Polycystic ovaries can be detected in post-menopausal women and have some of the same endocrine abnormalities which are evident in premenopausal women with polycystic ovaries, that is, raised serum concentrations of testosterone and triglycerides.

RESUMEN

Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a member of the epidermal growth factor family. In rodents HB-EGF has been found to mediate the mitogenic effects of oestrogen on the endometrial glandular cells and those of progesterone on the stromal cells. HB-EGF has also been found to be expressed at the site of implantation before any other discernible sign of blastocyst attachment in rodents. Our aim was to determine whether HB-EGF mRNA was expressed in the human pregnant and non-pregnant endometrial tissues. Normal endometrial tissues at different stages of the menstrual cycle, first trimester chorionic villi and decidua, second trimester chorionic villi and term placental tissues were snap frozen and stored at -80 degrees C. Reverse transcription-polymerase chain reaction (RT-PCR) was used to analyse the expression of HB-EGF mRNA in these tissues. HB-EGF mRNA was found to be expressed in human endometrium throughout the menstrual cycle. It was also present in first trimester chorionic villi and decidua, second trimester villi and term placenta. These findings suggest that HB-EGF may have a role in the growth or function of the human uterus, and that it may be important at the feto-maternal interface throughout pregnancy.

RESUMEN

AIM: To determine the failure rate of all female sterilisation procedures performed at National Women's Hospital in order to identify ways of improving the service. METHODS: A review was made of all sterilisation procedures performed at National Women's Hospital in 1988 and 1989. All patient notes and theatre records were examined. A consumer questionnaire was mailed to all patients monthly for 3 months. If there was no response efforts were made to contact these women via their last known general practitioner. Epsom Day Hospital where 95% of all terminations of pregnancy in Auckland are performed also examined their records. RESULTS: 1094 procedures were performed at National Women's Hospital in Auckland during 1988 and 1989. Failures were classified into two groups: those pregnant at the time of surgical procedure (administrative failures) and those pregnant after the procedure (surgical failure). There were 15 surgical failures (1.4%). Laparoscopy using Filshie clips was the most common method used and had a 1.2% surgical failure rate. Registrars had a 1.3% failure rate, consultants 1.9% and when both a consultant and registrar performed the procedure a failure rate of 0.7% was recorded. Eighty-six percent (6/7) of women who had a subsequent laparotomy after a failed sterilisation were found to have surgical misapplication of the occlusive device. There were 7 (0.6%) women who were pregnant at the time of the procedure. There were no patient or procedure-related factors which were associated with failures. CONCLUSION: Sterilisation is associated with a significant failure rate. Contraception counselling at the time of booking for the procedure needs to be improved. Preoperative pregnancy testing should be introduced to avoid sterilisation procedures in early pregnancy. Surgical misapplication of devices was a common cause of failure, not recanalisation as found elsewhere. From this review it would appear that the involvement of two surgeons lowers the failure rate.

RESUMEN

OBJECTIVE: to analyse all perinatal deaths at National Women's Hospital, Auckland, in a two year period, in order to identify areas in which changes could be made to improve the outcome for future pregnancies. METHODS: an audit was performed of all perinatal deaths at National Women's Hospital, Auckland, in 1989 and 1990. All deaths were classified according to the primary obstetric factor which initiated the sequence of events leading to the death. The events surrounding each death were examined for the presence of avoidable factors. RESULTS: there were 293 deaths after 20 weeks gestation, which included 172 fetal deaths, 116 neonatal deaths and five infant deaths. Fetal abnormality (24%) was the commonest cause of death followed by spontaneous prematurity (19%) and infection (11%). Fifty-one percent of the multigravid women who suffered a perinatal loss of a normally formed fetus had had a poor obstetric history. Avoidable factors were detected in 25% of all deaths. CONCLUSIONS: this audit clearly identified the causes of perinatal loss where improvements can be made. Advances in medical knowledge, technology and/or expertise are required to improve the outcome for the common causes of perinatal loss--fetal abnormality, prematurity and infection. Further staff and patient education with application of current knowledge and close attention to accepted standards of care should improve the outcome for the growth retarded fetus and the asphyxiated fetus in labour.
