Growth is an indicator of the health and nutritional status of infants and children. Health organisations and professionals worldwide advocate monitoring the growth of children with the primary aim of identifying and preventing malnutrition and/or obesity. Growth monitoring should be part of every health care consultation for children. However, physicians during health care consultations are often so busy addressing acute health issues, that they miss the opportunity to monitor the child's growth and provide anticipatory guidance. Appropriate growth monitoring would enable health care providers to detect abnormal growth in a timely manner, as well as to reassure parents if their concerns are unfounded. To perform this effectively, physicians need to be familiar with measurement methods, use of appropriate growth charts and interpretation of results. As weight, height and growth rates may vary among children, physicians also need to understand what constitutes normal growth. This paper aims to clarify the purpose of growth monitoring and provide recommendations for physicians to assess, monitor and manage growth in infants and children in a primary care setting.

INTRODUCTIONAlthough childhood autoimmune hepatitis (AIH) has been extensively investigated in the West, data on AIH in the East is lacking. We aimed to investigate AIH's clinical, biochemical and histological features, as well as its outcomes, in one of Singapore's two major paediatric units.
METHODSThis was a retrospective study of children diagnosed with AIH in the paediatric unit of National University Hospital, Singapore, over the last 12 years. Children with de novo AIH after liver transplantation were excluded. The demographic and clinical features of the patients, and their laboratory, treatment and clinical outcomes were reviewed.
RESULTSThis study comprised ten patients (six females, four males), with a median age of 5.1 (range 2.1-13.8) years at diagnosis. Five patients had inflammatory bowel disease (IBD). Seven patients had type 1 AIH, and three had autoimmune sclerosing cholangitis (ASC) and IBD; none had type 2 AIH. The median level of aspartate aminotransferase at diagnosis was 183 (range 45-2,649) U/L. Prednisolone 1 mg/kg/day was prescribed at diagnosis for eight patients. Two patients were lost to follow-up and were treated symptomatically when they re-presented with end-stage liver disease. Azathioprine or mycophenolate mofetil was prescribed after 3-7 months of treatment. Normalisation of aminotransferase levels took an average of 5.3 (range 1-39) months.
CONCLUSIONAIH is a rare but important cause of liver pathology. Children in this region with elevated aminotransferases or unexplained hepatomegaly should be screened for AIH.

INTRODUCTIONIn 2006, Singapore adopted the universal hepatitis B immunoglobulin (HBIg) policy. Since then, all infants of hepatitis B surface antigen (HBsAg)-positive mothers receive HBIg, irrespective of maternal hepatitis B e antigen (HBeAg) status. However, the benefits of HBIg for infants of HBeAg-negative mothers are unclear. We compared the vertical transmission rates among children of HBeAg-negative mothers who were given HBIg versus a retrospective cohort who were not given HBIg, to determine its protective effect.
METHODSThis observational study involved pregnant HBsAg-positive women seen at National University Hospital, Singapore, between June 2009 and December 2013. If the infants of these mothers completed the recommended vaccination schedule, they were recruited into the study, along with their older siblings. Serological testing for the children was performed three months after completion of the last dose of vaccine, and hepatitis B virus (HBV) surface gene sequencing was carried out if HBV DNA was detected.
RESULTSA total of 111 infants and 47 siblings were recruited. 2 (1.5%) children were found to have vertical transmission despite receiving HBIg, while no incidences of vertical transmission were found among the historical controls who did not receive HBIg (p = 1.00).
CONCLUSIONThe overall effectiveness of the hepatitis B vaccination programme for children of HBsAg-positive mothers was high, regardless of HBIg administration. The addition of HBIg did not appear to confer additional benefits, in terms of vertical transmission rate, among infants born to HBeAg-negative mothers.

INTRODUCTION:
As the traditional overnight call system was shown to contribute to fatigue, Singapore implemented a shift system in 2014. We aimed to compare activity levels, sleep (using a wrist actigraph), fatigue and professional quality of life between residents working on night float and those on overnight calls.
METHODS:
All Postgraduate Year 1 (PGY1) residents at our institution were invited to participate. Participants were required to wear a wrist actigraph for four months and complete two validated surveys (Epworth Sleepiness Scale [ESS] and Professional Quality of Life [ProQOL] scale) once each at the start and end of the study.
RESULTS:
49 residents were recruited. Night float and on-call residents showed a comparable median (range) number of steps (10,061 [1,195-15,923] vs. 10,649 [308-21,910]; p = 0.429), amount of sleep logged (361 [149-630] minutes vs. 380 [175-484] minutes; p = 0.369) and time taken to fall asleep (6 [0-14] minutes vs. 6 [range 0-45] minutes; p = 0.726), respectively. Night float residents had less efficient sleep, with 90.5% having sleep efficiency of over 85% compared to 100% of on-call residents (p = 0.127). More night float residents reported ESS scores > 10 (73.1% vs. 38.5%) and higher burnout scores on ProQOL scale (41.4% vs. 21.4%) at the start of the study. However, this was similar to the end of the study and not statistically significant.
CONCLUSION
Physical activity and amount of sleep were not significantly different between night float and on-call residents. Residents on night float reported comparatively more fatigue and burnout.

INTRODUCTION:
Infant gastroesophageal reflux disease (GERD) is a significant cause of concern to parents. This study seeks to describe GERD prevalence in infants, evaluate possible risk factors and assess common beliefs influencing management of GERD among Asian parents.
METHODS:
Mother-infant dyads in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) cohort were prospectively followed from preconception to 12 months post-delivery. GERD diagnosis was ascertained through the revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) administered at 4 time points during infancy. Data on parental perceptions and lifestyle modifications were also collected.
RESULTS:
The prevalence of infant GERD peaked at 26.5% at age 6 weeks, decreasing to 1.1% by 12 months. Infants exclusively breastfed at 3 weeks of life had reduced odds of GERD by 1 year (adjusted odds ratio 0.43, 95% confidence interval 0.19-0.97, P=0.04). Elimination of "cold or heaty food" and "gas producing" vegetables, massaging the infant's abdomen and application of medicated oil to the infant's abdomen were quoted as major lifestyle modifications in response to GERD symptoms.
CONCLUSION
Prevalence of GERD in infants is highest in the first 3 months of life, and the majority outgrow it by 1 year of age. Infants exclusively breastfed at 3 weeks had reduced odds of GERD. Cultural-based changes such as elimination of "heaty or cold" food influence parental perceptions in GERD, which are unique to the Asian population. Understanding the cultural basis for parental perceptions and health-seeking behaviours is crucial in tailoring patient education appropriately for optimal management of infant GERD.

INTRODUCTIONWe aimed to determine the prevalence and clinical manifestations of eosinophilic oesophagitis (EoE) in children who presented to a tertiary care hospital in Singapore.
METHODSWe conducted a retrospective review of all oesophageal biopsies taken during oesophagogastroduodenoscopy (OGD) from March 2010 to December 2011. The patients' demographics and clinical characteristics were collected. Biopsies were reviewed by a single pathologist who was blinded to the original reports, using the current consensus criteria for the histological diagnosis of EoE.
RESULTSOf the 88 children who had biopsies during OGD, 4 (4.5%) children (three boys, one girl; three Chinese, one Caucasian) were diagnosed with EoE. Their median age was 9.5 (range 4.0-12.0) years. The main clinical presentations were abdominal pain (in the three older children) and vomiting (in the youngest child). Three children had a history of atopy. Three children were diagnosed with EoE in the original histology reports, while one was diagnosed after the second review following histology demonstrating > 15 eosinophil granulocytes per high power field and microabscess formation. Endoscopy findings revealed oesophagitis in two children, one of whom was already on acid suppression therapy. Although three children were started on acid suppression therapy, they continued to be symptomatic. One child was also treated with swallowed fluticasone and two with food allergen avoidance, resulting in symptom improvement.
CONCLUSIONAlthough EoE is uncommon in Singapore, greater awareness is needed among family physicians and general paediatricians. Paediatric gastroenterologists should alert pathologists when sending biopsy specimens that are suspicious for EoE.
