We reviewed the deliveries in a teaching hospital in a multiracial community over the period of one year (1988), and investigated the relationship between maternal height, ethnic origin, and the extremes of birth weight with the likelihood of emergency lower segment caesarean section (LSCS). After excluding patients with obvious indications for LSCS, 5,050 patients were entered in the study. Chi-square analysis showed that the risk of emergency LSCS is significantly higher in the Indians compared to Chinese and Malays, but does not differ significantly between the latter two groups. Logistic regression analysis showed that birth weight of less than 2,500 g or greater than 3,500 g is the most significant association with emergency LSCS rate. Conditional logistic regression showed that, provided the individuals conformed to the characteristics of the cohort in this study, risk of emergency LSCS for a 150 cm (25th centile) tall Indian pregnant lady is almost twice that of a 158 cm (75th centile) tall non-Indian).
This is a survey on the present status of assisted reproductive technology in the Asia-Oceanic region. The survey formats were sent to the 19-member societies of AOFOG. By the end of August 1991, 11 countries responded: Australia, Egypt, Hong Kong, Israel, Japan, Malaysia, New Zealand, Philippines, Republic of China, Singapore and Thailand. This report is a summary of data from 12 countries including Korea. It comprised of 14 headings: IVF, GIFT, AIH, AID, donor sperm in ART, donor eggs in ART, preembryos from IVF for donation, cryopreservation of eggs, cryopreservation of fertilized eggs and preembryos, research of preembryos, surrogate mothers, additional procedures, quality assurance in reproductive technology and formation of policy for emerging reproductive technology. Each heading is composed of status of regulations, cost and coverage and the results and management of program.
When performed based on cytology, histological accuracy of the laser cone specimen improved with the more severe cytology. The incidence of adenocarcinoma in situ is 1.0%. With and without residual disease, the rate of abnormal cytology after laser excision cone are 0.6% and 1.6% respectively. There is good correlation between colposcopic biopsy and cone specimen in the more severe lesions. Out of 139 cases of incomplete excision, only 3 cases had abnormal cytology at follow-up. The complication rates are very low.
Hospital University Sains Malaysia (HUSM) functions as the state referral centre and the only hospital for the state of Kelantan that can offer neonatal intensive care service. The deliveries in HUSM with grand multiparity, late booking and problems of late referrals resembles a hospital serving a semiurban rather than an urban community. A comparison between the year 1989 and 1991 showed marked improvement of perinatal mortality rate from 41.32 to 24.88, which is significantly better than the improvement achieved from 1987 to 1989 (46.0 to 41.32). This was possible due to a marked fall in the early neonatal mortality rate from 10.02 in 1989 to 5.45 in 1991 and fall in the stillbirth rate from 31.61 to 19.53.
A prospective study of blocking T10-L1 with local anaesthetic, bilaterally in 30 patients undergoing caesarean section under general anaesthesia has been shown to provide effective postoperative analgesia thus requiring significantly less narcotics (mean 66.6 mg of pethidine) compared to the 30 patients in the control group (mean 163 mg of pethidine). A cocktail of 0.5% of bupivacaine with adrenaline and xylocaine 1% produced analgesia for the duration ranging from 8 to 12 hours (mean 8.4 hours). Patients with abdominal field block were awake, alert and comfortable during the immediate postoperative period. They were pain-free sufficiently to put the babies to the breast early and frequently.
Large ovarian cysts in the fetus are uncommon. Ultrasonography has helped in the detection of these cysts antenatally and in the newborn female infant. A case of bilateral ovarian cysts in a newborn is presented. The choice of management between conservative measures and surgical approaches remains controversial.
The social class distribution in 147 patients confirmed to have endometriosis at laparoscopy was done to see if the disease was associated with affluence. Two hundred and eighty-one patients confirmed not to have endometriosis was used as controls. The patients were derived from a background population for which the social class characteristics was known. Endometriosis was significantly (p < 0.001) associated with social class 1 and 2. However there was no association between social class distribution and the severity of the disease developed.
Sudden blindness in pregnancy is a devastating experience for the patient, her family and the treating obstetrician. Four cases of cortical blindness with pregnancy induced hypertension are presented, seen at the General Hospital Kota Bharu, Kelantan, in 1990. The incidence at the GHKB was 1: 1559 (4 cases out of 6,237 deliveries) which is higher as compared to neighbouring Singapore. The pathophysiology of this condition is still not well understood, though it is hoped that newer sophisticated imaging techniques like magnetic resonance imaging (MRI), CT scan, and blood flow waveform analysis by Doppler ultrasound will throw some light on the subject. Two of our cases presented with antepartum and two with postpartum cortical blindness. Therefore, termination of pregnancy alone may not provide the solution to this therapeutic dilemma.
The general lack of specialist obstetricians in a developing country such as Malaysia prompted us to develop a computer expert system for the management of fetal distress in rural hospitals. It was based on accepted production rules and implemented on a microcomputer. The clinical prototype was evaluated by 8 specialist obstetricians and 21 non-specialist doctors involved in obstetric care. The initial impression was that this type of expert system may help in diagnosis, decision-making and teaching.
A preterm baby was born to a multiparous mother by emergency caesarean section at 36 weeks of gestation. Apart from a depression on the right temporo-parietal region measuring 3 cm x 3 cm x 0.5 cm, no other abnormality was noted. A CT scan of the brain excluded the presence of intracranial haematoma and pressure effect on the brain. Spontaneous reduction of the fracture without any adverse neurological sequelae suggests that these fractures can be managed conservatively in some instances.
Out of 14,841 women who were serologically examined for syphilis at the antenatal booking clinic, University Hospital, Kuala Lumpur in Malaysia, 1.78% were VDRL positive and 1.05% TPHA positive with significant differences between the Malays, Indians and Chinese. These rates are higher than published series and were attributed to childhood yaws infection among the Malays. As differentiation between yaws and syphilitic infection in the clinic is difficult, all TPHA-reactive women were treated as for syphilis. Congenital syphilis was not diagnosed in those women who had been effectively treated before delivery.
Use of contraceptives by some selected characteristics was studied for married women in the reproductive age range (MWRA) in three south‐east Asian countries. The data were obtained from each country's national family planning/fertility survey conducted around the mid‐seventies. Only the gross relationship between each of the selected characteristics and contraceptive use was compared. The proportion of MWRA using contraceptives for Singapore was almost twice as high as the corresponding proportions for Peninsular Malaysia and Thailand. The pattern of contraceptive use was largely similar for Thailand and Malaysia but different from Singapore. The differences were largely attributed to the absence of a large rural population in Singapore, the apparently greater tendency of women in Singapore to use reversible contraceptive methods for birth spacing and the easier access by women to family planning information and services, particularly sterilisation, than in Peninsular Malaysia and Thailand.
Grandmultiparity is an ill defined term, but it is generally believed that increasing parity after the fifth delivery increases the risks of child bearing for both the mother and fetus. Four hundred seventy-seven women aged less than 35 years of parity 5 and above who delivered during one year period at the University Hospital, Kuala Lumpur were studied. There were 406 women of parity 5 and 6 and 71 women of parity 7 and above. The 2 groups as a whole comprised 7.5% of the obstetric population for that year. Obstetric performance in the 2 groups of grandmultipara was compared with 1,135 women, aged 25 to 34 years, having their second baby during the same period. Women of parity 7 and above were significantly more likely to be from lower socioeconomic groups, and suffer from anaemia, hypertension and pre-eclampsia. They were also significantly at risk of preterm delivery and delivering infants weighing less than 2.5 kg. In addition, the perinatal mortality rate was significantly greater in the highly parous group (Para greater than 7) than in women of parity 5 and 6 or the control group. Apart from a significant increase in the incidence of anaemia, women of parity 5 and 6 had a similar obstetric performance and perinatal outcome to that of the control group. We conclude that grandmultiparity per se is not an obstetric risk factor until after the seventh delivery. These findings have implications for those who plan the provision of obstetric services for the community.
The obstetric performance of 240 elderly primigravida delivering at the University Hospital, Kuala Lumpur, Malaysia between January 1987 and February 1990 was compared with a random group of 250 young primigravida delivering during the same time period. The incidence of impaired glucose tolerance, diabetes mellitus, preterm delivery, antepartum haemorrhage and malpresentation was all increased in the elderly primigravida group. The incidence of caesarean section in the older group was 40.4% compared with 6.8% in the younger (p less than 0.001). Recent studies suggest that the perinatal mortality in women who delay having their first baby until after the age of 35 is not significantly different from the rest of the obstetric population. However, in our own population of elderly primigravida, although not quite reaching statistical significance the perinatal mortality rate of 46 per 1,000 is three times that of primigravida aged 20-25. This may reflect our low induction rate (7.5%) and assisted vaginal delivery rate (8.3%) in those women in this high risk group who are allowed to labour. The implications of these findings are discussed.
The close epidemiological relationships between specific genital human papillomavirus (HPV) types and neoplasia of the cervix uteri have been extensively documented worldwide, including Singapore. Cervical cancer incidence rates in Singapore show variations between the major ethnic groups. To ascertain the corresponding HPV infection rates among the various races in Singapore, we analysed the cervical smears of 225 women by filter in situ DNA hybridization, and compared the data with a previous similar study. Fourteen (6.2%) individuals were HPV-positive, with HPV 16 and HPV 31 being the commonest types. No significant difference between HPV positivity rates in Chinese (5.0%) and in Malays (6.7%) was found, even though Chinese have a higher cervical cancer incidence than Malays. Furthermore, the cervical HPV carriage rate among women with normal cytology was 5.9%. In the light of reports of high genital HPV prevalence rates detected by DNA amplification, these data support the notion that HPV infection is commonly latent and requires the cooperation of other factors for cervical carcinogenesis.
Low birth weight babies are defined as those weighing under 2,500 g. They make 13.5% of all births at the Maternity Hospital, Kuala Lumpur but contribute to 74.8% of all deaths. They are most likely to be Indian babies and least likely to be Chinese. Among all 3 communities, the primigravidae tend to produce smaller babies than multiparae but this is also true for the Indian of parity more than 3. The Malay teenager is more likely to produce small babies than their older counterparts but not so with the Indian and Chinese. There are definite clinical factors associated with or causing the births of small babies and the lighter the baby, the more influential are these factors. Maternal hypertension, antepartum haemorrhage, multiple pregnancy and unexplained intrauterine death are the 4 outstanding associations with both low birth weight and perinatal death. Although the spontaneous (often premature) onset of labour was the commonest preceding factor, it was much less important in the lowest birth weight groups of babies and was a less important contributor to perinatal death.
A rare case of squamous cell carcinoma diagnosed in early pregnancy in a 28-year-old woman is described. At the time of radical surgery, which was carried out in the puerperium, the growth had already advanced to Stage IV disease. The rapid growth of the tumor seen in this patient suggests that although treatment needs to be individualised, the definitive radical surgery should not be delayed.
