INTRODUCTIONThere is currently a lack of representative data for local gestational age-specific size-at- birth percentile charts. Existing charts also suffer from limitations relating to the measurement of gestational age (GA) and an outdated population. We aim to construct reference values and charts for size-at-birth from 35 to 41 weeks, based on the healthy local population.

MATERIALS AND METHODSProspective observational birth cohort study which recruited pregnant mothers from the 2 major public hospitals with obstetric service in Singapore, at <14 weeks gestation and data was collected for birth weight, length and head circumference of infants born from November 2009 to May 2011. Percentile curves were created separately for male and female infants using the lambda-mu-sigma (LMS) method. The new percentile curves were then compared with other internationally published growth charts.

RESULTSSmoothened curves for birth weight, length and head circumference centiles were created from 863 infants (460 males, 403 females). Male infants consistently exceeded female infants in all 3 variables at each GA. For a male and female Singapore infant at 38 weeks gestation, the 10-50-90th centile values for weight would be 2663-3096-3597 vs. 2571-2966-3417 grams, for length 46.4-48.6-51.1 vs. 45.6-48.0-50.4 cm, and for head circumference 32.0-33.5-35.2 vs. 31.4-32.9-34.6 cm. There was no statistically significant difference between ethnic groups. On comparing our birth weight curves with data from Finland across all gestations, birth weights in our term infants (GA ≥37 weeks) were found to be lower across the 10-50-90th percentiles.

CONCLUSIONThe new centile charts in this study may be used as reference charts for size-at-birth for a subgroup of near-term and term infants. The use of foreign charts may lead to misclassification of small for gestational age (SGA) or large for gestational age (LGA) infants.

INTRODUCTIONThe physiological changes that occur in menopause alter sexual function and affect well-being. Hormonal changes contribute significantly to reduced sexual function in older women and sexual dysfunction may well be amenable to treatment with exogenous hormones or other agents.

MATERIALS AND METHODSRelevant clinical studies were identified by a computerised literature search. The collated data were presented to fellow gynaecologists for review, analysis of results and discussion in a series of meetings dedicated to finding the best evidence in menopause management. The evidence was assessed and used to prepare guidelines around the management of women who are affected by sexual dysfunction in menopause.

RESULTSHormone therapy benefits many women who have dyspareunia related to vaginal atrophy, reduced libido and decreased satisfaction, particularly if these symptoms adversely affect their quality of life. Alternative agents such as tibolone and sildenafil citrate can be useful adjuncts.

CONCLUSIONSIt is increasingly important to recognise postmenopausal sexual dysfunction. Treatment of this syndrome must be individualised to the specific complaints of each woman. Hormones and other agents are relevant treatment options for properly-selected women.

INTRODUCTIONIntrapartum fetal monitoring is essential for the identification of fetal hypoxia to reduce perinatal morbidity and mortality. Cardiotocography is associated with low specificity for fetal acidosis and poor perinatal outcome leading to unnecessary operative deliveries. ST waveform analysis of the fetal electrocardiogram has been shown to be a promising adjunctive intrapartum assessment tool. We aim to present the pathophysiology, the role of intrapartum monitoring and the practical usage of this relatively new technology in our review.

METHODSAn electronic search of Medline and OVID was carried out, followed by a manual search of the references identified by the electronic search.

RESULTSThe incorporation of ST waveform analysis to cardiotocography has been shown to reduce the rates of neonatal metabolic acidosis, moderate and severe neonatal encephalopathy, thus improving perinatal outcome. The reduction in operative delivery rates due to fetal distress is also significant. The pathophysiology and practical usage of this technology were discussed.

CONCLUSIONSWith more accurate identification of fetal hypoxia and reduction of unnecessary intervention rates, incorporation of ST waveform analysis of fetal electrocardiography into cardiotocography can improve the standard of intrapartum fetal monitoring.

INTRODUCTION: This study examined maternal, delivery and infant factors associated with cord thyroid-stimulating hormone (TSH) concentrations in an Asian population. METHODS: The Growing Up in Singapore Towards healthy Outcomes (GUSTO) study is a mother-offspring birth cohort from 2 major hospitals in Singapore. Cord serum TSH was measured using the Abbott ARCHITECT TSH Chemiluminescent Microparticle Immunoassay and the ADVIA Centaur TSH-3 Immunoassay. After excluding infants with a maternal history of thyroid disease, screening cord TSH results from 604 infants were available for multivariable regression analysis in relation to the factors of interest. RESULTS: Babies born by vaginal delivery had significantly higher cord serum TSH concentrations than babies born by caesarean section. Cord serum TSH concentrations differed significantly by measurement method. There was no association of cord TSH concentrations with ethnicity, sex, birth weight, gestational age, maternal body mass index, gestational weight gain, gestational diabetes mellitus status and other maternal, delivery and infant factors studied. CONCLUSION Interpretation of cord serum TSH results may need to take into account mode of delivery and measurement method.

INTRODUCTIONThis study records the prevalence and patterns of breastfeeding in Singaporean Chinese mothers who gave birth between 2000 and 2008.

MATERIALS AND METHODSThe Strabismus, Amblyopia and Refractive Error in Singaporean Children (STARS) study is a population-based survey conducted in South-Western Singapore. Disproportionate random sampling by 6-month age groups of Chinese children born from 2000 to 2008 was performed. The mothers (n = 3009) completed a standard questionnaire which recorded the initiation, content, method and duration of breastfeeding. World Health Organization (WHO) definitions for feeding content were used: Replacement (exclusive commercial formula or any liquid or solid/semi-solid food, excluding breast milk), Complementary (breast milk, solid/semi-solid foods, and any non-human liquid), and Exclusive (breast milk only, without additional food, drink or water). STARS-specific definitions for feeding method were used: Expressed (breast milk only fed via bottle, with no additional food or non-human liquid), Combination (breast milk and non-breast milk, fed via bottle and breast), and Direct (breast milk only fed via breast).

RESULTSBreastfeeding initiation (overall prevalence 77.0%) and duration increased over time, and were independently associated with higher maternal education: in 2000 and 2001, 68.6% of mothers initiated breastfeeding and 12.9% breast fed for or=6 months, vs 90.9% and 35.3%, respectively, of university-educated women (P <0.001). Expressed, Combination and Complementary feeding also increased, while Replacement feeding decreased (P <0.001). There was no difference in breastfeeding patterns by the child's gender.

CONCLUSIONSIn a population-based sample of Singaporean Chinese mothers giving birth from 2000 to 2008, breastfeeding initiation and duration increased over time and were independently associated with higher maternal education. This increase was associated with increased milk expression and complementary feeding. Thus awareness of breastfeeding benefits is rising in Singapore, but future health policies may need to target less-educated mothers.
