Abstract
BACKGROUND Exclusive Enteral Nutrition (EEN) induction in children with luminal Crohn's disease (CD) gives early mucosal healing (MH), but the long-term benefits of EEN-induced MH are just emerging. AIMS & METHODS We prospectively followed an Australian cohort of newly diagnosed children with predominantly luminal CD who completed at least six weeks EEN and with paired clinical Pediatric Crohn's Disease Activity Index (PCDAI), biochemical (C-reactive protein; CRP) and endoscopic assessment at diagnosis and post EEN. All commenced immunomodulators (IMs) early (<3 months from diagnosis) and had a minimum of 1 year follow-up. Complete MH was a simple endoscopic score for Crohn's disease (SES-CD) of 0, and SES-CD≥1 was ascribed to active endoscopic disease (aED) and further divided into near complete MH (SES 1-3), mild active disease (SES-CD 4-10) and moderate to severe disease (SES-CD>10). The primary outcome was long-term supervised sustained remission (SR) on IMs alone without need for corticosteroids, infliximab (IFX) or surgery. RESULTS A total of 54 eligible children (33 males) completing EEN induction were analysed. The median duration between pre and post EEN assessments was 60.5 days [interquartile range (IQR), 56-69.5]. Post EEN: clinical remission (PCDAI < 10) was observed in 45/54 (83%), and biochemical remission (PCDAI < 10 and CRP < 5 mg/dl) was observed in 39/54 (72%). Complete MH was observed in 18/54 (33%), near complete in 10/54(19%). SR was superior in those with complete MH vs. aED; 13/18, (72%) vs. 10/36 (28%), p = 0.003 at 1 year, 8/16, (50%) vs. 3/24, (8%), p = 0.008 at 2 years and (8/16, (50%) vs. 1/19, (6%), p = 0.005) at 3 years. Near-complete MH did not lead to superior SR. CONCLUSIONS Only complete MH post EEN induction predicts more favourable SR for up to 3 years.

Abstract
BACKGROUND In children, paracetamol overdose due to deliberate self-poisoning, accidental exposure or medication errors can lead to paediatric acute liver failure and death. In Australia and New Zealand, the nature of ingestion and outcomes of paracetamol-associated paediatric acute liver failure have not been described. OBJECTIVE To describe the nature and outcomes of paracetamol-associated paediatric acute liver failure. DESIGN Retrospective analysis of paracetamol-associated paediatric acute liver failure cases presenting 2002-2012. SETTING New Zealand and Queensland Paediatric Liver Transplant Services. RESULTS 14 of 54 cases of paediatric acute liver failure were attributed to paracetamol, the majority were secondary to medication errors. 12 of the 14 children were under the age of 5 years. Seven children received doses in excess of 120 mg/kg/day. Many of the other children received either a double dose, too frequent administration, coadministration of other medicines containing paracetamol or regular paracetamol for up to 24 days. Three children underwent transplant. One of these and one other child died. CONCLUSIONS In Australia and New Zealand, paracetamol overdose secondary to medication errors is the leading cause of paediatric acute liver failure. A review of regional safety practices surrounding paracetamol use in children is indicated.

Abstract
Current prognostic models in PALF are unreliable, failing to account for complex, non-linear relationships existing between multiple prognostic factors. A computational approach using ANN should provide superior modelling to PELD-MELD scores. We assessed the prognostic accuracy of PELD-MELD scores and ANN in PALF in children presenting to the QLTS, Australia. A comprehensive registry-based data set was evaluated in 54 children (32M, 22F, median age 17 month) with PALF. PELD-MELD scores calculated at (i) meeting PALF criteria and (ii) peak. ANN was evaluated using stratified 10-fold cross-validation. Outcomes were classified as good (transplant-free survival) or poor (death or LT) and predictive accuracy compared using AUROC curves. Mean PELD-MELD scores were significantly higher in non-transplanted non-survivors (i) 37 and (ii) 46 and transplant recipients (i) 32 and (ii) 43 compared to transplant-free survivors (i) 26 and (ii) 30. Threshold PELD-MELD scores ≥27 and ≥42, at meeting PALF criteria and peak, gave AUROC 0.71 and 0.86, respectively, for poor outcome. ANN showed superior prediction for poor outcome with AUROC 0.96, sensitivity 82.6%, specificity 96%, PPV 96.2% and NPV 85.7% (cut-off 0.5). ANN is superior to PELD-MELD for predicting poor outcome in PALF.

Abstract
UNLABELLED Pediatric liver transplantation is a successful procedure with 10-yr survival rate of 70%; following transplantation, the emphasis on promoting good quality of life is important. The increasing prevalence of allergic disorders in the general population and an increase in food allergy following solid organ transplantation are described in patients, especially in children, but the contribution to morbidity post-OLT has not been addressed. OBJECTIVES Identifying the incidence de novo allergies post-OLT performed by QLTS over 11 yr. METHODS Comprehensive medical record review of OLT recipients during study period. RESULTS From 1st July 1998 to 1st August 2009, 78 children received 85 cadaveric OLT; 60 children survived. Allergic disease was documented in 24/60 (40%) survivors. De novo food allergies were diagnosed in 12/60 (20%) (Table 2), 9/12 occurred in children who were infants at time of transplant. Ten of 12 had severe allergies, six anaphylactic; 6/60 (10%) carry an EpiPen. Only 31/60 (51%) diagnosed are followed in Queensland, suggesting severe allergic disease in our cohort is an underestimate. CONCLUSION Serious allergic disease post-OLT is clinically important, especially in infants at time of transplant, and should be targeted for specialist allergist referral and risk management.

Abstract
OBJECTIVE There are no objective ambulatory studies on the temporal relationship between reflux and cough in children. Commercial pHmetry loggers have slow capture rates (0.25 Hz) that limit objective quantification of reflux and cough. The authors aimed to evaluate if there is a temporal association between cough and acid pH in ambulatory children with chronic cough. DESIGN, SETTING AND PATIENTS The authors studied children (aged <14 years) with chronic cough, suspected of acid reflux and considered for pHmetry using a specifically built ambulatory pHmetry-cough logger that enabled the simultaneous ambulatory recording of cough and pH with a fast (10 Hz) capture rate. MAIN OUTCOME MEASURES Coughs within (before and after) 10, 30, 60 and 120 s of a reflux episode (pH<4 for >0.5 s). RESULTS Analysis of 5628 coughs in 20 children. Most coughs (83.9%) were independent of a reflux event. Cough-reflux (median 19, IQR 3-45) and reflux-cough (24.5, 13-51) sequences were equally likely to occur within 120 s. Within the 10 and 30 s time frame, reflux-cough (10 s=median 2.5, IQR 0-7.25; 30 s=6.5, 1.25-22.25) sequences were significantly less frequent than reflux-no cough (10 s=27, IQR 15-65; 30 s=24.5, 14.5-55.5) sequences, (p=0.0001 and p=0.001, respectively). No differences were found for 60 and 120 s time frame. Cough-reflux sequence (median 1.0, IQR 0-8) within 10 s was significantly less (p=0.0001) than no cough-reflux sequences (median 29.5, 15-67), within 30 s (p=0.006) and 60 s (p=0.048) but not within 120 s (p=0.47). CONCLUSIONS In children with chronic cough and suspected of having gastro-oesophageal reflux disease, the temporal relationship between acid reflux and cough is unlikely causal.

Abstract
Pediatric liver transplantation has proven so successful that 10-yr survival post-transplantation is in excess of 70% and following transplantation, emphasis of medical care switches from life saving to promotion of good quality of life. EE is an increasingly recognised phenomenon in the general population. Eosinophilic disorders of the GI tract are increasingly recognised in patient's post-solid organ transplantation but the contribution of EE to morbidity in this population has not been addressed to date. The objective of this study was to identify the incidence of EE in children receiving liver transplantation by the QLTS over the last 15.5 yr. Comprehensive review of medical records of all liver transplant recipients during study period via cross-checking procedural and electronic laboratory results was performed. All oesophageal biopsies reporting mucosal inflammation were reviewed. EE can be diagnosed when oesophageal biopsy reveals > or =5 eosinophils per HPF; however, we used a cut-off of 20 eosinophils per HPF, which is in accordance with current opinion. In the 159 children who received DD OLT, 130 survived and four have been diagnosed with EE (3%). Only 34 are currently followed in Queensland and all four patients diagnosed are in this cohort representing 12% of our follow-up clinic. Many patients are followed elsewhere so occurrence of EE in our total surviving population is an underestimate. EE is clinically important in the post-liver transplant community. Children post-OLT who have upper GI symptoms should be considered for endoscopic evaluation and biopsy to exclude EE.

Abstract
OBJECTIVES There is controversy in the literature regarding the effect of inflammatory bowel disease (IBD) on resting energy expenditure (REE). In many cases this may have resulted from inappropriate adjustment of REE measurements to account for differences in body composition. This article considers how to appropriately adjust measurements of REE for differences in body composition between individuals with IBD. PATIENTS AND METHODS Body composition, assessed via total body potassium to yield a measure of body cell mass (BCM), and REE measurements were performed in 41 children with Crohn disease and ulcerative colitis in the Royal Children's Hospital, Brisbane, Australia. Log-log regression was used to determine the power function to which BCM should be raised to appropriately adjust REE to account for differences in body composition between children. RESULTS The appropriate value to "adjust" BCM was found to be 0.49, with a standard error of 0.10. CONCLUSIONS Clearly, there is a need to adjust for differences in body composition, or at the very least body weight, in metabolic studies in children with IBD. We suggest that raising BCM to the power of 0.5 is both a numerically convenient and a statistically valid way of achieving this aim. Under circumstances in which the measurement of BCM is not available, raising body weight to the power of 0.5 remains appropriate. The important issue of whether REE is changed in cases of IBD can then be appropriately addressed.

Abstract
AIM Dipalmitoylphosphatidycholine (DPPC) is the characteristic and main constituent of surfactant. Adsorption of surfactant to epithelial surfaces may be important in the masking of receptors. The aims of the study were to (i) compare the quantity of free DPPC in the airways and gastric aspirates of children with gastroesophageal reflux disease (GORD) to those without and (ii) describe the association between free DPPC levels with airway cellular profile and capsaicin cough sensitivity. METHODS Children aged <14 years were defined as 'coughers' if a history of cough in association with their GORD symptoms was elicited before gastric aspirates and nonbronchoscopic bronchoalveolar lavage (BAL) were obtained during elective flexible upper gastrointestinal endoscopy. GORD was defined as histological presence of reflux oesophagitis. Spirometry and capsaicin cough-sensitivity test was carried out in children aged >6 years before the endoscopy. RESULTS Median age of the 68 children was 9 years (interquartile range (IQR) 7.2). Median DPPC level in BAL of children with cough (72.7 microg/mL) was similar to noncoughers (88.5). There was also no significant difference in DPPC levels in both BAL and gastric aspirates of children classified according to presence of GORD. There was no correlation between DPPC levels and cellular counts or capsaicin cough-sensitivity outcome measures. CONCLUSION We conclude that free DPPC levels in the airways and gastric aspirate is not influenced by presence of cough or GORD defined by histological presence of reflux oesophagitis. Whether quantification of adsorbed surfactant differs in these groups remain unknown. Free DPPC is unlikely to have a role in masking of airway receptors.

Abstract
BACKGROUND Gastroesophageal reflux disease (GORD) can cause respiratory disease in children from recurrent aspiration of gastric contents. GORD can be defined in several ways and one of the most common method is presence of reflux oesophagitis. In children with GORD and respiratory disease, airway neutrophilia has been described. However, there are no prospective studies that have examined airway cellularity in children with GORD but without respiratory disease. The aims of the study were to compare (1) BAL cellularity and lipid laden macrophage index (LLMI) and, (2) microbiology of BAL and gastric juices of children with GORD (G+) to those without (G-). METHODS In 150 children aged < 14-years, gastric aspirates and bronchoscopic airway lavage (BAL) were obtained during elective flexible upper endoscopy. GORD was defined as presence of reflux oesophagitis on distal oesophageal biopsies. RESULTS BAL neutrophil% in G- group (n = 63) was marginally but significantly higher than that in the G+ group (n = 77), (median of 7.5 and 5 respectively, p = 0.002). Lipid laden macrophage index (LLMI), BAL percentages of lymphocyte, eosinophil and macrophage were similar between groups. Viral studies were negative in all, bacterial cultures positive in 20.7% of BALs and in 5.3% of gastric aspirates. BAL cultures did not reflect gastric aspirate cultures in all but one child. CONCLUSION In children without respiratory disease, GORD defined by presence of reflux oesophagitis, is not associated with BAL cellular profile or LLMI abnormality. Abnormal microbiology of the airways, when present, is not related to reflux oesophagitis and does not reflect that of gastric juices.

Abstract
BACKGROUND Low bone mineral density (BMD) is recognised in individuals with cystic fibrosis (CF) although the pathogenesis remains unclear. The aims of this study were to compare BMD over a broad continuum of Australian individuals with CF with healthy controls and to examine the relationship between BMD and clinical parameters including physical activity, nutrition, and vitamin D levels. METHODS BMD of the lumbar spine (LS), total body (TB), femoral neck (FN), cortical wrist (R33%), and distal wrist (RUD) was examined in 153 individuals with CF aged 5.3-55.8 years (84 males) and in 149 local controls aged 5.6-48.3 years (66 males) using dual energy x ray absorptiometry. Anthropometric variables, body cell mass, markers of disease severity, corticosteroid usage, measures of physical activity, dietary calcium and caloric intake and serum vitamin D were assessed and related to BMD. RESULTS Compared with controls, mean BMD was not significantly different in children aged 5-10 years with CF. Adolescents (females 11-18 years, males 11-20 years) had reduced TB and R33% BMD when adjusted for age, sex, and height (difference in BMD (g/cm2) adjusted means between control and CF: TB=0.04 (95% CI 0.01 to 0.07); R33%=0.03 (95% CI 0.01 to 0.06)). BMD was reduced at all sites except R33% in adults (difference in BMD (g/cm2) adjusted means between control and CF: TB=0.05 (95% CI 0.02 to 0.09); LS=0.08 (95% CI 0.03 to 0.14); FN=0.09 (95% CI 0.03 to 0.15); RUD=0.03 (95% CI 0.01 to 0.05)). In children/adolescents BMD was weakly associated with nutritional status and disease severity. CONCLUSIONS BMD was normal in a well nourished group of prepubertal children with CF. A BMD deficit appears to evolve during adolescence and becomes more marked in adults. Individuals with CF should optimise nutrition, partake in physical activity, and maximise lung health in order to optimise BMD. Further longitudinal studies are required to understand the evolution of reduced BMD in young people and adults with CF.

Abstract
OBJECTIVE To review the outcome of acute liver failure (ALF) and the effect of liver transplantation in children in Australia. METHODOLOGY A retrospective review was conducted of all paediatric patients referred with acute liver failure between 1985 and 2000 to the Queensland Liver Transplant Service, a paediatric liver transplant centre based at the Royal Children's Hospital, Brisbane, that is one of three paediatric transplant centres in Australia. RESULTS Twenty-six patients were referred with ALF. Four patients did not require transplantation and recovered with medical therapy while two were excluded because of irreversible neurological changes and died. Of the 20 patients considered for transplant, three refused for social and/or religious reasons, with 17 patients listed for transplantation. One patient recovered spontaneously and one died before receiving a transplant. There were 15 transplants of which 40% (6/15) were < 2 years old. Sixty-seven per cent (10/15) survived > 1 month after transplantation. Forty per cent (6/15) survived more than 6 months after transplant. There were only four long-term survivors after transplant for ALF (27%). Overall, 27% (6/22) of patients referred with ALF survived. Of the 16 patients that died, 44% (7/16) were from neurological causes. Most of these were from cerebral oedema but two patients transplanted for valproate hepatotoxicity died from neurological disease despite good graft function. CONCLUSIONS Irreversible neurological disease remains a major cause of death in children with ALF. We recommend better patient selection and early referral and transfer to a transplant centre before onset of irreversible neurological disease to optimize outcome of children transplanted for ALF.

Abstract
OBJECTIVES To evaluate the effect of sucrose solution given by mouth on infant crying times and measures of distress in the immunisation clinic. DESIGN Randomised, double blind, placebo controlled trial of sucrose solution 75% wt/vol v sterile water as a control. SETTING The immunisation clinic of the Women's and Children's Hospital, Adelaide. PATIENTS A total of 107 healthy infants attending for 2, 4, or 6 month immunisations with polio by mouth (Sabin), intramuscular diphtheria, tetanus, and pertussis (DTP), and intramuscular Haemophilus influenzae type b were randomised to receive 2 ml 75% sucrose solution or sterile water by mouth before the two injections. METHODS The duration of infant crying was recorded during and immediately after two intramuscular immunisations and infant distress was assessed by a visual analogue scale (Oucher scores) independently by a nurse and a parent. RESULTS The administration of 2 ml 75% sucrose solution by mouth reduced the infant crying time and Oucher distress scores after immunisation with DTP/H influenzae type b. CONCLUSIONS Infant immunisation by intramuscular injection is a distressing procedure for infants and parents. Sucrose solution at a high concentration reduces infant distress and is safe and clinically useful in this setting.

Abstract
OBJECTIVE To investigate the prevalence of carbohydrate malabsorption and bacterial overgrowth in children with cystic fibrosis (CF) and abnormal stool pattern referred for breath hydrogen testing. METHODS Results from 89 tests using lactose, sucrose and lactulose in 54 children with CF were compared with 5430 tests on children with non-CF-related stool abnormalities. RESULTS Children with CF were more frequently unable to ferment lactulose to hydrogen (39% vs. 20%, P<0.03); they had significantly longer oro-caecal transit times (mean 99 vs. 68 min, P<0.0003); they had a higher incidence of bacterial overgrowth (32% vs. 7%, P<0.003) and sucrose malabsorption (47% vs. 14.5%, P<0.004); but they had no increase in lactose malabsorption (40% vs. 31%). Children with bacterial overgrowth in both groups had longer transit times (CF 123 min, non-CF 108 min) compared to the non-CF children without overgrowth (68 min) and reference normal children (69 min). CONCLUSIONS Bacterial overgrowth and carbohydrate malabsorption, particularly of sucrose, should be considered when assessing children with CF and abnormal stool patterns.

Abstract
Anti-Helicobacter pylori antibodies were determined in 157 institutionalised Cantonese children, mean age 9.5 +/- 3.9 (SD) years, with profound neurodevelopmental disabilities. Eighty-seven (55.4%) were H. pylori seropositive compared with four of 50 (8%, P > 0.0002) of an age-matched control group, mean age 7.2 +/- 4.3 (SD) years. Eight of 15 seropositive children with a recent history of upper gastrointestinal bleeding underwent endoscopy and in all cases gastric infection with H.pylori was confirmed. Anthropometric data from institutionalised children revealed marked malnutrition but showed no significant difference between seropositive and seronegative children. Disabled children receiving long-term residential care in Hong Kong are confirmed to be at increased risk of H.pylori infection.

Abstract
This pediatric hospital-based study of 388 diarrhea cases and 306 controls analyzed predominant E. coli colonies from primary culture (253 cases and 177 controls) with eight DNA probes for enteropathogenic, enterotoxigenic, enteroaggregative, and diffusely adherent E. coli. Only enteropathogenic E. coli adherence factor was identified significantly more frequently in cases (10) than in controls (0).

Abstract
To determine the role of enteric pathogens in acute childhood diarrhoea in Hong Kong, 388 children with diarrhoea and 306 children of similar age without diarrhoea were evaluated in a hospital-based study during a one-year period from August 1994 to July 1995. Of the diarrhoeal cases, 55% were under 1 year and 95% were below 5 years of age. On admission, 22% had some dehydration but none was severely dehydrated. All children were well nourished. Oyer 60% of children with diarrhoea had one or more pathogens in their stool. Rotavirus was the most commonly isolated pathogen (34.6%), followed by Salmonella (23.3%), Campylobacter (4.7%) and Shigella (2.1%). Rotavirus was not assessed in the controls and was detected mainly during the winter months December to February. Bacterial pathogens were identified more commonly in diarrhoea patients (30%) than in controls (5.6%) (P < 0.001). Despite rapid recent socioeconomic development in Hong Kong, non-typhoidal Salmonella diarrhoea remains a significant local problem in infants under 1 year. Further detailed assessment of the transmission and prevention of this infection is required.

Abstract
A pair of preterm twins developed fatal necrotizing enterocolitis (NEC) in association with Staphylococcus epidermidis septicaemia after receiving contaminated expressed breast milk (EBM). S. epidermidis NEC can be associated with severe bowel inflammation, high morbidity and mortality. Breast milk is the most suitable nutrient for preterm infants but EBM should undergo regular screening for bacterial overgrowth. We urge caution before administering EBM found to be heavily contaminated with S. epidermidis to preterm infants.

Abstract
Three consecutive term infants diagnosed as suffering from idiopathic persistent pulmonary hypertension of the newborn (PPHN) were tried on high frequency oscillatory ventilation (HFOV) after failure of conventional mechanical ventilation (CMV). All experienced a significant improvement in oxygenation. All three infants survived. HFOV was utilised in a fourth term infant initially diagnosed as having idiopathic PPHN with an immediate benefit. This infant subsequently died and was found at autopsy to have a lethal congenital maldevelopment of pulmonary microcirculation. No serious adverse effects were encountered with HFOV in contrast to the use of pharmacologic agents where hypotension was a serious problem. A therapeutic trial of HFOV is simple and efficient, and would not cause undue delay in the commencement of other rescue therapy should it prove unsuccessful. We predict HFOV will replace non-specific vasoactive agents as the standard first line alternative to CMV for the treatment of idiopathic PPHN.

Abstract
A 3-year survey of subaponeurotic haemorrhage (January 1991 to December 1993) in a tertiary referral centre in Hong Kong revealed that the incidence of this life-threatening condition was 6.4 per 1000 ventouse-associated deliveries, which is 60-fold more common than with other modes of childbirth. We highlight a lesser known phenomenon of marked male predominance (male to female ration 8:1). Three of 18 (17%) infants with subaponeurotic haemorrhage died. Severe subaponeurotic haemorrhage with a decrease in venous haematocrit >25% of the baseline value at birth and requiring urgent blood transfusion in the first 12 h, in association with significant birth asphyxia with arterial cord blood pH <7.20 and 1-min Apgar score < or = 3 were the most important risk factors for death. A worrying feature was the silent presentation of occult subaponeurotic haemorrhage in two of the fatal cases. Frequent monitoring of haematocrit, early and rapid restoration of blood volume and prompt commencement of cardiac inotropes are the keys to the management of this condition, which should be suspected in all ill newborn infants subjected to the ventouse applicator.

Abstract
We report a case of misalignment of pulmonary vessels and review the clinical features of all 13 cases reported to date. All were term infants dying from severe persistent pulmonary hypertension of the newborn. We have identified a triad of features that will alert neonatal clinicians to the possibility of this diagnosis: association with other non-lethal congenital malformations; delayed onset of presentation (especially after 12h); and severe hypoxaemia refractory to conventional therapy. We recommend that any autopsy on newborn infants include a specific search for misalignment of pulmonary vessels to outline the pathophysiology and clinical significance of this disorder.

Abstract
A 24 week gestation survivor of congenital Candida pneumonia who received prompt antifungal treatment and modern neonatal intensive care is reported. It was an unusual case in that fungal chorioamnionitis occurred without a foreign body in the maternal genital tract. Early diagnosis and treatment of congenital fungal pneumonia was possible because of prior knowledge of the obstetric history. Amphotericin B was successfully used for the treatment of this condition but combination with fluconazole (a fungistatic agent) was unsatisfactory and may be undesirable. Dexamethasone therapy to assist extubation was instituted once the fungal infection had been successfully controlled.
