Abstract
BACKGROUND Parent-completed tools like the Ages and Stages Questionnaire Third Edition (ASQ-3) are important in developmental screening. As a screening tool, a high negative predictive value (NPV) is critical to avoid missing the diagnosis of developmental delay. This study evaluated the NPV and accuracy of the ASQ-3 in assessing the development of preterm infants. METHODS Infants born at <32 weeks and/or <1250 grams, presenting to the Neonatal Neurodevelopmental Clinic at the Singapore General Hospital for follow-up from January 2014 to June 2017, at 6, 12, and 18 months corrected age, were included. The ASQ-3 and standardized tests - Peabody Developmental Motor Scale-Second Edition (PDMS-2) and Preschool Language Scale, Fourth Edition UK (PLS-4 UK) - were administered. ASQ-3 gross motor and fine motor scores were compared to PDMS-2 at 6 and 12 months, and ASQ-3 communication scores to PLS-4 UK at 18 months. RESULTS At 6 months (n = 145), NPV for gross motor and fine motor were 96.4% (accuracy 80.0%) and 95.4% (accuracy 77.2%) respectively. At 12 months (n = 127), NPV for gross motor and fine motor were 88.9% (accuracy 79.8%) and 82.8% (accuracy 74.0%) respectively. At 18 months (n = 113), NPV for language was 56.9% (accuracy 63.7%). CONCLUSIONS The ASQ-3 showed high NPV and accuracy in screening gross motor and fine motor skills at 6 and 12 months, but not in screening language skills at 18 months. Judicious use of the ASQ-3 may allow for more effective utilization of resources.

Abstract
Trapped fourth ventricle (TFV) as a complication of post-hemorrhagic hydrocephalus (PHH) is widely reported in the pediatric population with a prior history of ventriculo-peritoneal (VP) shunt placement. Characterized by disproportionate dilatation of the fourth ventricle on serial neuro-imaging, it is rarely encountered in the early course of preterm infants and the differentiating clinical features are subtle and non-specific. Clinical alertness and sonographic correlation hold the key to early diagnosis. We report an early emergence of TFV in an extremely low gestational age newborn (ELGAN) following fulminant Pseudomonas aeruginosa meningitis, approach to management, and the neurological outcome. Fourth ventricle entrapment as a complication of perinatally acquired Pseudomonas aeruginosa meningitis in a surviving ELGAN is extremely rare.

Abstract
Background The optimal way for antimicrobial stewardship programs (ASPs) to interact with existing infectious disease physician (IDP) services within the same institution is unknown. In our institution, IDPs and our prospective audit and feedback ASP operate independently, with occasionally differing recommendations offered for the same inpatient. We performed a retrospective audit on inpatients that had been reviewed by both IDPs and ASP within a 7-day period, focusing on cases where different therapy-modifying recommendations had been offered. We analyzed the outcomes in inpatients where the ASP recommendations were accepted and compared these with the inpatients where the IDP recommendations were accepted instead. Outcomes assessed were 30-day mortality post-ASP review, unplanned re-admission within 30 days post-discharge from hospital, and clinical deterioration at 7 days post-ASP review. Findings There were 143 (18.9%) patients where differing recommendations had been offered, with primary physicians accepting 69.9% of ASP recommendations. No significant differences in terms of demographics, clinical characteristics, 30-day mortality, and re-admission rates were observed, although clinical deterioration rates were lower in patients where the ASP recommendation was accepted (8.0% vs. 27.9%; p = 0.002). On multivariate analysis, hematology-oncology inpatients were associated with unplanned readmission. Increasing age and hematology-oncology inpatients were associated with clinical deterioration 7 days post-recommendation, whereas acceptance of ASP recommendations was protective. No characteristic was independently associated with 30-day mortality. Conclusion In conclusion, independent reviews by both IDPs and ASPs can be compatible within large tertiary hospitals, providing primary physicians even in situations of conflicting recommendations viable alternative antimicrobial prescribing advice.

Abstract
Antimicrobial stewardship is an emerging field currently defined by a series of strategies and interventions aimed toward improving appropriate prescription of antibiotics in humans in all healthcare settings. The ultimate goal is the preservation of current and future antibiotics against the threat of antimicrobial resistance, although improving patient safety and reducing healthcare costs are important concurrent aims. Prospective audit and feedback interventions are probably the most widely practiced of all antimicrobial stewardship strategies. Although labor-intensive, they are more easily accepted by physicians compared with formulary restriction and preauthorization strategies and have a higher potential for educational opportunities. Objective evaluation of antimicrobial stewardship is critical for determining the success of such programs. Nonetheless, there is controversy over which outcomes to measure and there is a pressing need for novel study designs that can objectively assess antimicrobial stewardship interventions despite the limitations inherent in the structure of most such programs.

Specialist trainees on rotation cannot replace dedicated consultant clinicians for antimicrobial stewardship of specialty disciplines. Antimicrob Resist Infect Control 2012; 1:36.

Abstract
Our prospective-audit-and-feedback antimicrobial stewardship (AS) program for hematology and oncology inpatients was switched from one led by dedicated clinicians to a rotating team of infectious diseases trainees in order to provide learning opportunities and attempt a “de-escalation” of specialist input towards a more protocol-driven implementation. However, process indicators including the number of recommendations and recommendation acceptance rates fell significantly during the year, with accompanying increases in broad-spectrum antibiotic prescription. The trends were reversed only upon reverting to the original setup. Dedicated clinicians play a crucial role in AS programs involving immunocompromised patients. Structured training and adequate succession/contingency planning is critical for sustainability.

Abstract
INTRODUCTION Current medical advances have increased the survival rate of the premature infant with its complications. Risk factors for prematurity include maternal diabetes mellitus, hypertension, smoking and alcohol intake. METHODS A true/false questionnaire survey focusing on risk factors, outcomes/follow-up and costs was administered to adults attending a parenting-related public forum. One point was awarded per correct answer. Entire prematurity knowledge and section T-scores were calculated, (a pass mark was defined as at least 50 percent for each T-score). Missing answers and affected T-scores were considered invalid. RESULTS There were 81 respondents: predominantly within 21-40 years of age, Chinese, female, public-housing dwellers, first-time parents-to-be and with graduate or higher-level qualifications. A pass in entire and prematurity knowledge T-scores was achieved in 69 percent (median 13 [range 3-21]) and 62 percent (median 12 [range 0-19]) respectively. A pass in section T-scores on risk factors, outcomes and costs was achieved in 62, 53 and 75 percent, respectively. Awareness of risks and outcomes did not correlate with awareness of costs. Logistic regression did not reveal any factors contributing to a pass or higher T-scores. CONCLUSION Although the majority achieved a pass in all T-scores, general knowledge among this childbearing group was deemed inadequate by the median scores. As survival improves, awareness of prematurity and its risks has to be improved, with a target to reduce the incidence of prematurity and to support those infants who require resource-intensive follow-up.

Abstract
INTRODUCTION Cultural, religious and personal factors impact greatly on parenting. This survey aims to identify gaps in knowledge and perception about common parenting issues, with respect to mandarin-speaking Chinese in Singapore. There is an emphasis on first-time parents, who the authors feel may be the group which will require additional education and support on these issues. METHODS A 37-item written survey was conducted before a public mandarin-language forum. Our response rate was 67 percent. RESULTS Only 44 percent felt that paediatricians allocated sufficient time to discuss parenting issues. 99 percent of parents believed that breast milk was better than formula milk and that 93 percent intended to breastfeed. However, the vast majority of respondents thought that breastfeeding should be stopped if jaundice developed, and that sunning was effective in preventing jaundice. Moreover, the majority did not recognise the seriousness of jaundice, prolonged or otherwise. Widespread misconceptions existed about milk formulas, with half of the respondents thinking that it was necessary to change to lactose-free formula once a child developed diarrhoea. The majority also thought that certain milk formulas could help improve IQ. CONCLUSION We hope that more comprehensive and accessible parental education will be available to aid in raising awareness of parental practices, and to dispel misconceptions regarding neonatal care.

Abstract
Radix notoginseng, the root of Panax notoginseng (Burk.) F. H. Chen, has been widely used in traditional Chinese medicine. Its main components, saponins, have been reported to have many pharmacological activities. To test the general assumption that herbs of a single species planted and harvested from a single location are uniform in chemical and genetic makeup, chemical analysis and DNA fingerprinting were carried out. High-performance TLC together with HPLC analysis were used to analyze 17 randomly sampled 3-year-old roots from a single farm for the presence of six saponins. Five roots showed distinct chemical profiles with changed ratios of ginsenosides Rd/Rg1, Re/Rg1, or Rb1/Rg1. The same samples, together with some 1- and 2-year-old samples, were also subjected to fluorescent amplified fragment length polymorphism (AFLP) analysis, and their internal transcribed spacer 2 (ITS 2) regions were sequenced. Fluorescent AFLP analysis was found to be much more polymorphic than the ITS 2 sequence and showed clear evidence of genetic diversity within the tested population. In conclusion, genetic diversity and variation of saponin contents between individual P. notoginseng roots have been detected. We suggest that genetic diversity affects the contents of the six saponins. The saponin contents variation and genetic diversity were also found among P. notoginseng root samples collected from China and Singapore markets. Since variable saponin contents may affect therapeutic efficacy, combining the use of genetic profiling with chemical profiling will help ensure greater uniformity in the quality of P. notoginseng roots. The genetic and chemical diversity within a population also provides the opportunity for breeding new cultivars with more desirable chemical constituents.

Abstract
INTRODUCTION To determine whether chronic lung disease (CLD) influences specific aspects of motor development in infancy. MATERIALS AND METHODS Twenty-nine very low birthweight infants with CLD at 36 weeks' post-conceptional age and 31 infants without CLD were evaluated at 8 months' and 24 months' corrected age using the Neurosensory Motor Development Assessment. Perinatal and neonatal characteristics of the infants with CLD and control infants were compared using the chi-square test for categorical variables and Student's t-test for continuous variables. The relationship between CLD and adverse outcome was measured by the odds ratio (OR) and its 95% confidence interval (CI). RESULTS The overall developmental scores of the CLD infants were significantly different compared with control infants at 8 months. By 2 years of age, both groups of infants showed marked improvement in motor performance. However, differences persisted in the area of postural balance and sensory motor skills. Taking periventricular haemorrhage and periventricular leukomalacia into consideration, CLD contributed significantly to the occurrence of motor dysfunction at 8 months of age [odds ratio (OR), 7.4; 95% confidence interval (CI), 2.1 to 26.5]. The impact of CLD on motor development remained substantial, though not statistically significant (OR, 3.7; 95% CI, 0.4 to 37.9) at 2 years of age. CONCLUSION CLD has a definite effect on motor development. The pathologic influence of CLD on motor development remains speculative but results of this study emphasise the need for careful neurodevelopmental follow-up of infants with CLD, whether or not these infants suffer intraventricular haemorrhage or periventricular leukomalacia.

Abstract
INTRODUCTION To determine the incidence, risk factors and need for surgery for retinopathy of prematurity (ROP) among very-low-birth-weight (VLBW) infants. MATERIALS AND METHODS This was a retrospective study of all VLBW infants managed by the department over 14 years, from 1988 to 2001. Preterm infants were examined according to the Royal College of Ophthalmologists' guidelines, and retinopathy was graded following the International Classification of ROP. All VLBW infants examined for ROP were included and data were retrieved retrospectively and analysed for maternal, medical, obstetric and neonatal risk factors using logistic regression. RESULTS Of the 564 VLBW infants who fit the screening criteria, ROP was detected in 165 (29.2%) of VLBW infants; of whom 49% of infants had stage 1 disease, 24% were at stage 2, and 27% were at stage 3 or more. Among 45 infants with stage 3 disease or more, treatment was needed in 62.2% (28/45). No ROP was detected in infants greater than 33 weeks of gestation. Only 0.6 % (1/164) of infants greater than 30 weeks of gestational age (GA) needed surgery for ROP. Using birth weight (BW) criteria, stage 3 ROP was noted only in 1% (6/564) of infants with BW >1000 g. Of all ROP requiring surgery, 89% (25/28) of infants were <1000 g as compared to 11% (3/28) who were >1000 g infants. The median age of onset of ROP was 35 weeks (range, 31 to 41) corrected age. By univariate analysis for threshold ROP, preeclampsia, prenatal betamethasone exposure, gestational age, birth weight, 1-minute Apgar score, hyaline membrane disease (HMD), surfactant usage, hypotension, septicaemia, intraventricular haemorrhage duration of supplemental oxygen, ventilation and chronic lung disease were associated with ROP requiring surgery (i.e., threshold ROP, P <0.05). However, using multiple logistic regression analyses for ROP, maternal preeclampsia [odds ratio (OR), 2.52; confidence interval (CI), 1.32 to 4.7], birth weight (OR, 0.99; CI, 0.996 to 0.999), pulmonary haemorrhage (OR, 4.61; CI, 1.04 to 20.4), duration of ventilation (OR, 1.06; CI, 1.04 to 1.08) and duration of continuous positive airway pressure (CPAP) (OR, 1.02; CI, 1.01 to 1.04) were factors predictive of development of threshold ROP. CONCLUSION The incidence of ROP among VLBW infants was 29.2%. ROP was strongly associated with smaller, more immature and sicker infants. The median age of onset of ROP was 35 weeks (range, 31 to 40 weeks) postmenstrual age. Infants <30 weeks of GA and/or infant with BW <1000 g are at considerable risk for threshold ROP. The main risk factors for development of threshold ROP by regression analysis are maternal preeclampsia, birth weight, and presence of pulmonary haemorrhage, duration of ventilation and continuous positive pressure ventilation. We suggest that both immaturity and compromised pulmonary function are both important aetiological factors in the development of ROP. Prevention of prematurity, control of preeclampsia, judicious use of ventilation and oxygen therapy are the only promising factors that may reduce the incidence and severity of ROP in this high-risk infant.

Abstract
INTRODUCTION Childhood developmental and behavioural disorders are increasingly being recognised, with high demands for earlier diagnosis and intervention. In Singapore, referrals to the Child Development Unit, KK Women's and Children's Hospital, originate mainly from primary health care practitioners, who therefore should have adequate baseline knowledge of normal development as well as common developmental and behavioural disorders. METHODOLOGY A pilot study, using a questionnaire survey, was conducted, with the aim of assessing existing knowledge in childhood developmental and behavioural paediatrics amongst a cohort of general practitioners (GPs) in Singapore. True/False questions on normal development as well as developmental disorders such as autistic spectrum disorder (ASD), attention deficit/hyperactivity disorder (ADHD) and learning disability, were structured. These disorders were selected because of their relatively higher prevalence. RESULTS A total of 48 GPs were surveyed, representing 2% of non-specialists practising in the private sector. The median total score (T-score) was 9 (range 6 to 13) of a possible 14. Only just over a-third of the group achieved the pass rate (defined arbitrarily as 75%) for T-score, with two-thirds replying correctly to all questions on normal development. Scores for factual ASD/ADHD questions were also not ideal, with some myths being believed as truths. CONCLUSION The scores reflect knowledge and educational deficits in developmental paediatric medicine amongst the study cohort. Expected to provide holistic care and counselling, these GPs are currently insufficiently equipped with the necessary knowledge and skills to support families of special-needs children. Education and training programmes in this aspect of paediatric medicine are clearly needed, through the organisation of CME lectures and incorporation of various developmental topics into the training curriculum. This will enable early identification and diagnosis of childhood developmental and behavioural disorders, which will in turn allow greater optimisation of potential and functionality in these special-needs children.

Abstract
INTRODUCTION To describe the characteristics, the immediate and short-term outcome and predictors of mortality in normal-birth-weight (NBW) infants admitted to a tertiary neonatal intensive care unit (NICU) in Singapore. MATERIALS AND METHODS We retrospectively reviewed the medical records of 137 consecutive NBW infants admitted to the NICU of the Singapore General Hospital from January 1991 to December 1992. Data on the diagnoses, clinical presentation of illness, intervention received, complications and outcome as well as follow-up patterns for the first 2 years of life, were collected and analysed. RESULTS NBW NICU infants comprised 1.8% of births in our hospital and 40.8% of all NICU admissions. The main reasons for NICU admissions were respiratory disorders (61.3%), congenital anomalies (15.3%) and asphyxia neonatorum (11.7%). Respiratory support was necessary in 81.8%. Among those ventilated, the only predictive factor contributing to mortality was the mean inspired oxygen concentration. The mortality rate was 11.7%. Causes of death included congenital anomalies (43.75%), asphyxia neonatorum (31.25%) and pulmonary failure secondary to meconium aspiration syndrome (12.5%). The median hospital stay among survivors (88.3%) was 11.0 (range, 4 to 70) days. Of 42 patients (out of 117 survivors) who received follow-up for at least 6 months, 39 infants did not have evidence of any major neurodevelopmental abnormalities at their last follow-up visit, prior to or at 2 years of age. CONCLUSIONS Despite their short hospital stay (compared to very-low-birth-weight infants), the high volume of NBW admissions make the care of this population an important area for review to enhance advances in and hence, reduce the cost of NICU care. With improved antenatal diagnostic techniques (allowing earlier and more accurate diagnosis of congenital malformations) and better antenatal and perinatal care (allowing better management of at-risk pregnancies), it is anticipated that there should be a reduction in such admissions with better outcomes. Close follow-up of this high-risk group of infants is also important in order to offer early intervention to those who may possibly have perinatally-related developmental difficulties.

Abstract
OBJECTIVE To study the efficacy, safety and cost effectiveness of recombinant human erythropoietin (r-HuEPO) in reducing erythrocyte transfusion needs in very low birthweight (VLBW) infants. METHODS We conducted a non-blind randomized controlled trial and assigned 100 VLBW infants, less than 33 weeks gestation, to receive either r-HuEPO 750 U/kg per week subcutaneously from day 5 to day 40 or no erythropoietin (EPO). Infants received oral iron 3-6 mg/kg per day from day 10. Transfusion needs were analysed for all enrolled infants and in five weight subgroups: birthweight of less than 600 g, 600-799 g, 800-999 g, 1000-1199 g and infants more than 1200 g. RESULTS VLBW infants on r-HuEPO attained higher reticulocyte counts and haematocrit than control infants but the mean number of transfusions and volume of erythrocyte transfused per infant were not statistically different. Of infants 800-999 g at birth, the mean number of transfusions per infant was 2.1 compared with 3.5 transfusions per control infant (P = 0.04). Volume of erythrocytes transfused was 34.9 +/- 32.1 mL/kg in r-HuEPO-treated infants and 56.6 +/- 25.8 mL/kg in control infants (P = 0.03). The cost per patient for transfusion and EPO was S$388 for r-HuEPO recipient and S$438 for control infant. Blood pressure, neutrophil count, platelet count and complications of prematurity were not significantly different in both groups of VLBW infants. CONCLUSION r-HuEPO at 750 U/kg per week stimulates erythropoiesis in VLBW infants but significantly reduces the need for erythrocyte transfusion only in infants weighing 800-999 g at birth.

Abstract
We report the case of a newborn Indian girl with congenital sodium diarrhoea (CSD) who presented typically in utero, in whom diagnosis was made from markedly raised stool sodium in the presence of an alkaline stool. Treatment with sodium citrate normalised her metabolic and electrolyte status but resulted in transient uremia necessitating supplementation with sodium bicarbonate instead. She died at 11 weeks old following re-admission in a moribund state with grossly increased abdominal distension. Her fatal outcome in infancy suggests that CSD has a wide spectrum of clinical severity.

Abstract
OBJECTIVES To determine the incidence, clinical spectrum and outcome of very low birthweight (VLBW) infants with chronic lung disease (CLD), and evaluate associated factors. METHODOLOGY Retrospective review of 265 VLBW infants managed in the NICU from January 1988 to December 1992. RESULTS The overall neonatal survival rate for VLBW infants was 83%. Sixty-five (25%) infants had CLD, of whom 42% had severe CLD. Mortality in infants with CLD was 11%. In contrast with infants without CLD, CLD infants had significantly higher risk of adverse neurodevelopment with cerebral palsy documented in 13.5% and functional disability recorded in 34.6% at 2 years corrected age. Factors associated with the development of CLD included; decreasing birthweight (OR 0.98, CI 0.97-0.99), septicaemia (OR 4.96, CI 1.57-15.65), necrotizing enterocolitis (OR 119.07, CI 4.98-2845.04), hyaline membrane disease (OR 5.34, CI 1.83-15.55), patent ductus arteriosus (OR 4.46, CI 1.75-11.36) and increasing fraction of inspired oxygen concentration in the first week of life (OR 1.09, CI 1.04-1.14). CONCLUSIONS Chronic lung disease occurs frequently in VLBW infants and is associated with a high incidence of adverse neurodevelopment. Further studies to clarify the role of non-respiratory factors such as patent ductus arteriosus (PDA) and sepsis in the pathogenesis of CLD may reduce the incidence or prevent the development of CLD in these preterm infants.

Abstract
The prevalence of inguinal hernia during primary hospitalization was determined in 250 infants with gestational age 24-29 weeks. Fourteen per cent developed hernia, with prevalence significantly higher in boys than girls. Infants with respiratory distress syndrome and those requiring prolonged mechanical ventilation were significantly predisposed to the development of hernia. Male infants, especially those who required prolonged ventilatory assistance, were at greatest risk. This information may be used when counselling parents regarding complications of very preterm infants.

Abstract
This study addresses the dilemma of whether to attempt resuscitation of the previously undiagnosed fresh stillborn infant and evaluates factors predictive of survival and long-term outcome. We reviewed the clinical spectrum, immediate complications and long-term outcome of 45 successfully resuscitated apparently stillborn infants (34 term, 11 preterm) who were admitted to the Intensive Care Nursery. Significant obstetric and intrapartum events were identified in 34 (75%) infants while 11 (25%) had no apparent risk factors. Of the 39 infants with neonatal complications, 37 had hypoxic-ischaemic encephalopathy (HIE: Sarnat stage 1 in 5, stage 2 in 15, stage 3 in 17); 12 (27%) had oliguria, 10 (22%) had hypotension, 7 (16%) experienced hypoglycaemia, 4 (9%) had disseminated intravascular coagulopathy (DIC) and 1 (2%) had persistent pulmonary hypertension of the newborn (PPHN). Fourteen infants (31%) died in the neonatal period and four (9%) died during infancy. Risks of death and adverse neurodevelopment were significantly increased in infants with stage 2 or 3 HIE (P < 0.005). Follow-up assessment of 24 of the 27 surviving infants revealed a normal outcome in 15 (63%), severe disability in six (25%), moderate disability in two (8%) and mild disability in one (4%) infant. The positive predictive value of stage 2 or 3 HIE was 70% for mortality and 80% for morbidity. One-third (15/45) of successfully resuscitated apparently stillborn infants were normal at follow-up assessment and the outcome for these infants was predicted with complete accuracy by the stage of HIE present during the neonatal period.

Abstract
Thirty-two cases of hydronephrosis caused by pelvi-ureteric junction obstruction, presenting to the Department of Paediatric Surgery in the last 6 years were reviewed. In both infants and older children a palpable abdominal mass was the most common mode of presentation. Anderson-Hynes pyeloplasty was performed in a total of 31 kidneys. In 4 children, whose kidneys were severely hydronephrotic and with hardly any renal parenchyma present a primary nephrectomy was performed. Of the two children who required further operation on the same kidney, a repeat pyeloplasty for persistent obstruction was required in 1 patient, the other patient underwent nephrectomy subsequent to pyeloplasty as a severe pyonephrosis had developed. Twenty-nine of the 31 kidneys were assessed postoperatively by tube nephrogram, intravenous pyelogram (IVP), or diuretic renography. Four kidneys were found to be non-functional or severely damaged.
