Delivery of macrosomic babies: management and outcomes of 330 cases

Lim JH, Tan BC, Jammal AE, Symonds EM

J Obstet Gynaecol, 2002 Jul;22(4):370-4.
PMID: 12521456

This study reviews the deliveries of macrosomic babies and their outcomes. A total of 330 macrosomic (birth weight > or =4 kg) cases were studied retrospectively from July 1999 to December 1999 in the Maternity Hospital of Kuala Lumpur. The variables studied included induction of labour, mode of delivery and the incidence of maternal and perinatal complications. Three hundred and thirty macrosomic infants were delivered during the period of study. Vaginal delivery was achived in 56% of the study cases. The percentage of vaginal delivery was higher among those who had induction of labour (63%) compared to the group without induction of labour (50%). Vaginal delivery was planned in 267 mothers and of these 69% achieved vaginal delivery. Twelve per cent of the macrosomic infants were delivered by elective caesarean section. Shoulder dystocia occurred in 4.9% of vaginal deliveries. Eighty-eight neonates were admitted to the special care nursery unit and 57% of these infants were delivered by elective caesarean section. Perineal trauma occurred in 26% of vaginal deliveries. Post-partum haemorrhage occurred in 32% of caesarean deliveries compared to 4% in vaginal deliveries. Two cases of stillbirths were documented but no maternal death occurred during the period of study. Vaginal delivery is the most frequent mode of delivery for a fetus weighing in excess of 4 kg and vaginal delivery should be attempted in the absence of contraindications, because vaginal delivery has less maternal morbidity compared to caesarean delivery. However, shoulder dystocia remains a significant complication of vaginal delivery for macrosomic fetuses.

Jamaiah I, Anuar AK, Najib NA, Zurainee MN

Med J Malaysia, 1998 Mar;53(1):6-9.
PMID: 10968130

Over a period of ten years (1983-1992), 134 malaria cases admitted to University Hospital, Kuala Lumpur (UHKL) were analysed. Malays constituted 27.6%, Chinese 29.8%, Indians 9.7%, Indonesians 16.4% and other foreigners 16.4%. Therefore, of the total number of cases, foreigners constituted 32.8% (44) of all the malaria cases admitted to UHKL. Fifteen of these foreigners had chloroquine-resistant strains of malarial parasites. Three species of malaria were reported of which Plasmodium falciparum constituted the most (46.3%) (80% of these developed resistance to chloroquine). Plasmodium vivax was confirmed in 44.8% (10% of these developed resistance to chloroquine) and there was only one case of Plasmodium malarie infection.

Stereotactic neuroendoscopic management of hydrocephalus: a three-year follow-up and analysis of Malaysian children with aqueduct stenosis

Abdullah J, Ariff AR, Ghazaime G, Naing NN

Stereotact Funct Neurosurg, 2001;76(3-4):175-80.
PMID: 12378096

The beneficial effects of stereotactic third ventriculostomy versus ventriculoperitoneal shunt were evaluated in 62 paediatric patients and analysed in relation to age, sex, clinical history, presence of meningomyelocele, magnetic resonance imaging measurements of hydrocephalus and third ventricle floor size. The third ventriculostomy were done on 50 patients using the Richard-Wolf Caemaert Endoscope and the Leksell Stereotactic Frame Model G. These patients were operated using the 4-French Fogarty catheter to open the base of the third ventricle. During the same period of study 12 paediatric patients with aqueduct stenosis who were managed by ventriculoperitoneal shunt were included. Both surgical procedures were compared. Statistically univariate analysis revealed that those patient with an age group of more than six months undergoing ventriculostomy had good outcome. Multivariate analysis revealed that past history of haemorrhage and/or meningitis were predictors of poor outcome. Sex, size of lumbar meningocele at birth, abnormal ventricular anatomy or narrow third ventricular floor size were non predictors of bad outcome in these patients. There was no difference in outcome in both the shunt or ventriculostomy group.

Glucose-6-phosphate dehydrogenase (G6PD) variants in Malaysian Chinese

Ainoon O, Joyce J, Boo NY, Cheong SK, Zainal ZA, Hamidah NH

Hum Mutat, 1999 Oct;14(4):352.
PMID: 10502785 DOI: 10.1002/(SICI)1098-1004(199910)14:4<352::AID-HUMU1

We screened 38 G6PD-deficient male Chinese neonates for known G6PD mutations using established PCR-based techniques. We found 50.0% (19 of 38) were mutation 1376G>T, 34.2% (13 of 38) were mutation 1388G>A, 5.2% (2 of 38 ) were mutation 95A>G and 2.2% (1 of 38) was mutation 1024C>T. In 7% (3 of 38) of the cases the mutations remained uncharacterised. Sixty three percent (24 of 38) of the G6PD deficient neonates had neonatal jaundice with 28.9 % (11 of 38) developing moderate to severe hyperbilirubinemia. The group of neonates with 1388 mutation showed the highest incidence of moderate to severe hyperbilirubinemia requiring phototherapy and/or exchange transfusion respectively. Majority (70%) of the G6PD deficient neonates showed severe enzyme deficiency. However, there was no meaningful association between the level of enzyme activity and the severity of neonatal jaundice. In summary, four mutations account for more than 90% of the G6PD deficiency cases among the Chinese in Malaysia and the pattern of distribution of the molecular variants is similar to those found among the Chinese in Taiwan and southern mainland China. Our findings also suggest the possible association of nt 1388 mutation with severe neonatal jaundice.

Comparison of parenting stress between Malaysian mothers of four-year-old very low birthweight and normal birthweight children

Ong LC, Chandran V, Boo NY

Acta Paediatr, 2001 Dec;90(12):1464-9.
PMID: 11853347 DOI: 10.1080/08035250152708905

A study was carried out to compare parenting stress between 116 mothers of very low birthweight (VLBW) children and 96 mothers of normal birthweight (NBW) children at 4 y of age, using the Parenting Stress Index (PSI). Multiple regression analysis was used to determine factors associated with child-domain stress (CDS) and parent-domain stress (PDS). There was a significantly higher proportion (39.7%) of mothers of VLBW children with high CDS scores >90th percentile than mothers of NBW children (20.8%). No significant differences were observed for PDS scores. Lower intelligence quotient (IQ) scores and adverse child behaviour, as evidenced by higher Child Behavior Checklist (CBCL) scores, were significantly associated with higher CDS scores (p < 0.001). Factors associated with higher PDS scores were higher CBCL scores (p < 0.001), mothers who were the primary caregivers (p < 0.001), male sex (p = 0.018) and lower level of maternal education (p = 0.048). These factors remained statistically significant even when physically and cognitively impaired children were excluded from the analysis.

CONCLUSION: Specific child characteristics and the social environment appear to have a greater impact on parenting stress than the biological risk of VLBW birth per se.

Rotavirus electropherotypes from the Kuala Lumpur Hospital: a re-examination after an interval of seven years

Yap KL, Lim YH, Tan SC

Malays J Pathol, 1998 Jun;20(1):25-30.
PMID: 10879260

The objective of this study was to ascertain the extent changes have occurred in the epidemiology of human rotavirus electropherotypes from the same location 7 to 8 years after an earlier study. Genomic RNA profiles of rotaviruses from diarrhoeic children admitted to the Kuala Lumpur Hospital from April to December 1996 were determined by polyacrylamide gel electrophoresis and silver staining. A total of 179 group A rotaviruses were detected from 870 children: 175 with legible staining of all RNA segments were classified into 14 distinct electropherotypes (10 and 4 with long and short migration patterns respectively). In addition, the results revealed: high predominance of long pattern electropherotypes (94% of the total electropherotypes); most long electropherotypes with RNA profiles which all 11 RNAs migrated separately (8 of 10 electropherotypes); all short electropherotypes had segments 2 and 3 that co-migrated; presence of a very numerically dominant electropherotype (75% of all electropherotypes); frequent co-circulation of the dominant electropherotype-present throughout the study period--with other electropherotypes present for limited periods; sequential temporal appearances by similar electropherotypes. These observations were similar to that of an earlier study conducted in 1988/89. Nevertheless, the dominant electropherotype in the present study was different and not among the electropherotypes detected in the earlier study.

Risk factors associated with neonatal hypothermia during cleaning of newborn infants in labour rooms

Cheah FC, Boo NY

J Trop Pediatr, 2000 Feb;46(1):46-50.
PMID: 10730042

Cleaning newborn infants with coconut oil shortly after birth is a common practice in Malaysian labour rooms. This study aimed: (1) to determine whether this practice was associated with a significant decrease in the core temperature of infants; and (2) to identify significant risk factors associated with neonatal hypothermia. The core temperature of 227 randomly selected normal-term infants immediately before and after cleaning in labour rooms was measured with an infrared tympanic thermometer inserted into their left ears. Their mean post-cleaning body temperature (36.6 degrees C, SD = 1.0) was significantly lower than their mean pre-cleaning temperature (37.1 degrees C, SD = 1.0; p < 0.001). Logistic regression analysis showed that the risk factors significantly associated with pre-cleaning hypothermia (< 36.5 degrees C) were: (1) not being placed under radiant warmer before cleaning p = 0.03); and (2) lower labour room temperature (p < 0.001). Logistic regression analysis also showed that the risk factors significantly associated with post-cleaning hypothermia were: (1) lower labour room temperature (p < 0.001); (2) lower pre-cleaning body temperature (p < 0.001); and (3) longer duration of cleaning (p = 0.002). In conclusion, to prevent neonatal hypothermia, labour room temperature should be set at a higher level and cleaning infants in the labour room should be discouraged.

Glucose-6-phosphate dehydrogenase (G6PD) variants in Malaysian Malays

Ainoon O, Yu YH, Amir Muhriz AL, Boo NY, Cheong SK, Hamidah NH

Hum Mutat, 2003 Jan;21(1):101.
PMID: 12497642 DOI: 10.1002/humu.9103

We performed DNA analysis using cord blood samples on 86 male Malay neonates diagnosed as G6PD deficiency in the National University of Malaysia Hospital by a combination of rapid PCR-based techniques, single-stranded conformation polymorphism analysis (SSCP) and DNA sequencing. We found 37.2% were 871G>A (G6PD Viangchan), 26.7% were nt 563 C>T (G6PD Mediterranean) and 15.1% were 487G>A (G6PD Mahidol) followed by 4.7% 1376G>T (G6PD Canton), 3.5% 383T>C (G6PD Vanua Lava), 3.5% 592C>T (G6PD Coimbra), 2.3% 1388G>A (G6PD Kaiping), 2.3% 1360C>T (G6PD Union), 2.3% 1003G>A (G6PD Chatham), 1.2% 131C>G (G6PD Orissa) and 1.2% 1361G>A (G6PD Andalus). Seventy-one (82.6%) of the 86 G6PD-deficient neonates had neonatal jaundice. Fifty seven (80%) of the 71 neonates with jaundice required phototherapy with only one neonate progressing to severe hyperbilirubinemia (serum bilirubin >340 micromol/l) requiring exchange transfusion. There was no significant difference in the incidence of neonatal jaundice, mean serum bilirubin level, mean age for peak serum bilirubin, percentage of babies requiring phototherapy and mean number of days of phototherapy between the three common variants. In conclusion, the molecular defects of Malay G6PD deficiency is heterogeneous and G6PD Viangchan, Mahidol and Mediterranean account for at least 80% of the cases. Our findings support the observation that G6PD Viangchan and Mahidol are common Southeast Asian variants. Their presence in the Malays suggests a common ancestral origin with the Cambodians, Laotians and Thais. Our findings together with other preliminary data on the presence of the Mediterranean variant in this region provide evidence of strong Arab influence in the Malay Archipelago.

Randomized controlled study of the effects of different durations of light exposure on weight gain by preterm infants in a neonatal intensive care unit

Boo NY, Chee SC, Rohana J

Acta Paediatr, 2002;91(6):674-9.
PMID: 12162601

A randomized controlled study was carried out on 96 preterm infants (< 37 wk) with birthweight less than 2000 g admitted to a neonatal intensive care unit. The aim was to compare the weight gain between preterm infants exposed to 12 h cyclical lighting (intensity of light: 78.4 +/- 24.7 lux, mean +/- SD) and those exposed to a continuously dim environment (5.9 +/- 1.9 lux). The exclusion criteria were infants with major congenital malformations or who needed continuous lighting for treatment procedure and care. From day 7 of life until discharge, 50 infants were randomized to receive 12 h cyclical lighting and 46 infants to a continuously dim environment. There was no significant difference in the mean birthweight (12 h lighting vs continuously dim: 1482 vs 1465 g, p = 0.8), mean gestational age (31.6 vs 31.4 wk, p = 0.6), median duration of hospital stay (28.5 vs 28.5 d, p = 0.8), mean age to regain birthweight (13.0 vs 12.9 d, p = 0.3), mean weight gained by day 14 (27.6 vs 36.2 g, p = 1.0), median weight gain per day (11.9 vs 12.2 g, p = 0.9) or median body weight on discharge (1800 vs 1800 g, p = 0.4) between the two groups of infants.
CONCLUSION: Exposing preterm infants to either 12 h cyglical lighting or continuously dim environment did not have any significant effect on their weight gain during the neonatal period.

Fulltext The effectiveness of surfactant replacement therapy for preterm infants with respiratory distress syndrome

Lim WL, Lim CT, Chye JK

Med J Malaysia, 1998 Dec;53(4):376-84.
PMID: 10971981

Thirty preterm infants weighing > or = 800 g with clinical and radiological evidence of respiratory distress syndrome (RDS) requiring mechanical ventilation with FiO2 of > or = 40% were given modified bovine surfactant (Survanta). They were compared with equal number of historical controls. Infants who received surfactant showed prompt and highly significant improvement in FiO2, mean airway pressure, arterial/alveolar oxygen tension ratio and ventilatory index. There was significant improvement in mortality rate (10% vs 33%; p = 0.03). Among the survivors, surfactant-treated infants required shorter duration of continuous positive airway pressure (CPAP) (3.4 vs 9.6 days; p = 0.04). For survivors with birthweight of > 1000 g, surfactant-treated infants required shorter duration of ventilatory support (intermittent positive pressure ventilation + CPAP) (7.5 vs 18.9 days, p = 0.02). Overall, surfactant-treated infants achieved full enteral feeds sooner (15.7 days vs 24.6 days; p = 0.03) and required shorter duration of total parenteral nutrition (13.9 days vs 25.6 days; p = 0.02). We concluded that surfactant replacement therapy was effective in the treatment of preterm infants with RDS.

Predictors of failure of nasal continuous positive airway pressure in treatment of preterm infants with respiratory distress syndrome

Boo NY, Zuraidah AL, Lim NL, Zulfiqar MA

J Trop Pediatr, 2000 Jun;46(3):172-5.
PMID: 10893920

A case-control study was carried out on 97 consecutive preterm (< 37 weeks) infants to determine predictors associated with failure of nasal continuous positive airway pressure (CPAP) in the treatment of respiratory distress syndrome (RDS). Logistic regression analysis showed that only three risk factors were significantly associated with failed CPAP. These were: moderate or severe RDS (odds ratio: 5.9; 95 per cent confidence interval (CI): 2.2-16.0); septicemia during CPAP therapy (OR: 8.8; 95 per cent: CI 1.5-50.7); and pneumothorax during CPAP therapy (odds ratio: 6.9; 95 per cent: CI 1.1-41.7).

Observations on obstetric practice in a multicultural setting

TambyRaja RL

Matern Child Health J, 1999 Jun;3(2):111-3.
PMID: 10892419

Singapore provides a rich environment for investigations into ethnic differences in pregnancy outcome, as it is populated by Malays, Indians, and Chinese. Years of clinical practice and obstetric research in this environment have affirmed the observation that many factors interact in determining length of gestation and birth weight, and that these factors have differential affects among these three different ethnic groups. Although technological advances have furthered our understanding of obstetrical outcomes and provided essential tools to promote the survival of premature infants, the persistent use of uniform growth standards hampers our ability to assure positive outcomes for women of different ethnicity. Recognition of ethnic differences has resulted in declines in certain negative pregnancy outcomes for women in Singapore. The development of race-specific uterine growth curves will enhance the provision of perinatal care for all women.

Gastro-oesophageal reflux: clinical profiles and outcome

Lee WS, Beattie RM, Meadows N, Walker-Smith JA

J Paediatr Child Health, 1999 Dec;35(6):568-71.
PMID: 10634985

OBJECTIVES: To assess the clinical features, investigations and outcome of 69 children (40 males, 29 females) with gastro-oesophageal reflux (GOER) referred to a tertiary referral centre in paediatric gastroenterology.
METHODS: A study of all patients with significant GOER seen at the Paediatric Gastroenterology Unit, Queen Elizabeth Hospital for Children, Hackney Road, London, between December 1994 and August 1995.
RESULTS: The median age at referral was 16 months. Presenting symptoms were recurrent vomiting (72%), epigastric and abdominal pain (36%), feeding difficulties (29%), failure to thrive (28%) and irritability (19%). Continuous 24-h lower oesophageal pH studies performed in 57 children showed 20 (35%) had a reflux index of between 10% to 20%, 14 (25%) had a index > 20%, and six (11%) had a postprandial reflux index > 10%. Reflux was shown in 38 (62%) of 62 children who underwent barium studies. None had significant anatomical abnormalities, but in the 22 children who had a negative barium studies, six had severe reflux (reflux index > 20%). Upper gastrointestinal endoscopy performed in 47 children showed reflux oesophagitis in 29 (62%), oesophageal ulceration in three, and Barrett's oesophagus in one. All of the children were treated with standard medical therapy. Sixty-six per cent were able to discontinue medication within 12 months and remained well. Four children (6%) required Nissen's fundoplication for failure to respond to medical therapy.
CONCLUSIONS: Most infants with GOER have an uncomplicated course. False negative results were noted in both pH monitoring and barium meal. Up to 80% of children, with therapy, will improve within 12 months.

The predictive value of extremes of birth weight, mother's height and ethnic origin on the likelihood of emergency caesarean section

Hin LY, Khairuddin Y, Ng KB

Asia Oceania J Obstet Gynaecol, 1994 Dec;20(4):389-94.
PMID: 7832671

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).

Maternal and child health in urban Sabah, Malaysia: a comparison of citizens and migrants

Zulkifli SN, U KM, Yusof K, Lin WY

Asia Pac J Public Health, 1994;7(3):151-8.
PMID: 7794653 DOI: 10.1177/101053959400700302

This paper describes selected maternal and child health indicators based on a cross-sectional study of citizens and migrants in Sabah, Malaysia. A total of 1,515 women were interviewed from a multi-stage random sample of households in eight urban centers. Among the 1,411 women in the sample who had experienced a pregnancy before, 76% were local citizens and 24% were migrants. There were statistically significant differences between citizens and migrants in ethnicity, religion, education, household income, and access to treated water supply and sanitary toilet facilities. Significantly fewer migrants practiced any form of contraception and obtained any antenatal care during any pregnancy. Furthermore, citizens tended to initiate care as early as three months but migrants as late as seven months. Despite these differences, only the infant mortality rate, and not pregnancy wastage, was statistically significantly higher among migrants. Pregnancy interval was also similar between the two groups. The influence of several socioeconomic factors on pregnancy wastage and infant mortality was explored.

Surfactant protein A and stable microbubble formation in tracheal aspirates

Cheong KB, Cheong SK, Boo NY

Malays J Pathol, 1996 Dec;18(2):101-5.
PMID: 10879230

This study aimed to determine the role of surfactant protein A (SP-A) in the formation of stable microbubble in tracheal aspirates. Our results showed that as the concentration of anti SP-A antibodies added to tracheal aspirate specimens increased, the number of stable microbubble formed in the specimen decreased. The correlation between stable microbubble counts and the SP-A levels in the tracheal aspirates was good, r = 0.85, p < 0.05. This study suggests that SP-A plays an important role in stable microbubble formation. Measurement of small stable microbubbles is thus a useful bedside test for predicting the SP-A activity in the tracheal aspirates and in indirect measurement of lung maturity.
