Abstract
OBJECTIVE Variables predicting outcome of high-grade squamous intraepithelial lesion (HSIL) in pregnancy are unknown. The HSIL is usually managed conservatively during pregnancy. We aim to assess morphological features of HSIL diagnosed during pregnancy and identify variables predicting HSIL outcome in pregnant and non-pregnant women. METHODS ThinPrep pap smears with HSIL in pregnant (2014-2019) and non-pregnant females (2017-2019) were identified. The pathology material from follow-up cervical samples was reviewed by two participating pathologists (TP and KS). Regression was defined as benign or residual low-grade squamous intraepithelial lesion. Histological findings were recorded and compared between pregnant and non-pregnant cohort. RESULTS The HSIL regression rate was higher in colposcopic samples (16% vs. 0%; p=0.05) and follow up excisions (27% vs. 23%) from pregnant cohort. Overall regression rate was higher in pregnant versus non-pregnant cohort (34% vs. 23%; p=0.1). The stromal inflammation was prominent in biopsies from pregnant cohort (p=0.02). Presence of CIN 2 (versus CIN 3) in non-pregnant cohort predicted HSIL regression (p=0.04). The time to biopsy and excision (from pap smear) was significantly higher in pregnant cohort (p=0.0001). HSIL histological features (nuclear pleomorphism, hyperchromasia, nuclear contour irregularity, nuclear to cytoplasmic ratio, and mitosis) and HPV types were similar in both cohorts and did not predict regression. CONCLUSION The higher rate of benign findings during HSIL follow up in pregnancy is likely related to duration and stromal inflammation. HSIL regression is frequently noted following CIN2 diagnosis in non-pregnant setting. HSIL histology is similar in postpartum and non-pregnant females.

Abstract
Background Research studies to inform clinical practice and policy in children and young people with appendicitis are hampered by inconsistent selection and reporting of outcomes. The aim of this study was to develop a core outcome set for reporting all studies of uncomplicated acute appendicitis in children and young people. Methods Systematic literature reviews, qualitative interviews with parents and patients treated for uncomplicated acute appendicitis, and a Study‐Specific Advisory Group informed a long list of outcomes. Outcomes were then prioritized by stakeholders based in the UK (patients, parents, and paediatric and general surgeons) in an online three‐round Delphi consensus process, followed by face‐to‐face consensus meetings. Results A long list of 40 items was scored by 147 key stakeholders in the first Delphi round, of whom 90 completed the two subsequent Delphi rounds. The final core outcome set comprises 14 outcomes: intra‐abdominal abscess, reoperation (including interventional radiology procedure), readmission to hospital, bowel obstruction, wound infection, antibiotic failure, wound complication, negative appendicectomy, recurrent appendicitis, death, patient stress/psychological distress, length of hospital stay, time away from full activity and child's quality of
life. Conclusion A core outcome set comprising 14 outcomes across five key domains has been developed for reporting studies in children and young people with uncomplicated acute appendicitis. Further work is required to determine how and when to measure these outcomes.

Abstract
BACKGROUND Certain migrant groups are more likely to develop a psychotic disorder compared to the native-born populations, and a younger age at migration is associated with greater risk. However, it is not known at which stage migration has an effect on the development of psychotic disorders. We examined whether migrants were more likely to be identified as ultra-high risk for psychosis (UHR) compared to native-born young people and whether migrant status was associated with the risk of transition to a full-threshold psychotic disorder. METHODS The cohort included all young people aged 15-24 who were identified as UHR at a specialist clinic over a five-year period (2012-16). Australian census data were used to obtain the at-risk population. Poisson regression was used to calculate rate ratios and Cox regression analysis determined hazard ratios. RESULTS 467 young people were identified as UHR, of which 13.5% (n = 63) were born overseas. First-generation migrants were 2.6-fold less likely to be identified as UHR compared to Australian-born young people (IRR = 0.39, 95% CI [0.30, 0.51], P < 0.001). There was no difference between migrant and native-born young people in their risk of transitioning to a psychotic disorder (HR = 0.90, 95% CI [0.39, 2.08], P = 0.81). CONCLUSIONS UHR first-generation migrants may be under-accessing mental health services.

Abstract
AIM OF THE STUDY Complex tracheo-oesophageal fistulae (TOF) are rare congenital or acquired conditions in children. We discuss here a multidisciplinary (MDT) approach adopted over the past 5 years. METHODS We retrospectively collected data on all patients with recurrent or acquired TOF managed at a single institution. All cases were investigated with neck and thorax CT scan. Other investigations included flexible bronchoscopy and bronchogram (B&B), microlaryngobronchoscopy (MLB) and oesophagoscopy. All cases were subsequently discussed in an MDT meeting on an emergent basis if necessary. MAIN RESULTS 14 patients were referred during this study period of which half had a congenital aetiology and the other half were acquired. The latter included button battery ingestions (5/7) and iatrogenic injuries during oesophageal atresia (OA) repair. Surgical repair was performed on cardiac bypass in 3/7 cases of recurrent congenital fistulae and all cases of acquired fistulae. Post-operatively, 9/14 (64%) patients suffered complications including anastomotic leak (1), bilateral vocal cord paresis (1), further recurrence (1), and mortality (1). Ten patients continue to receive surgical input encompassing tracheal/oesophageal stents and dilatations. CONCLUSIONS MDT approach to complex cases is becoming increasingly common across all specialties and is important in making decisions in these difficult cases. The benefits include shared experience of rare cases and full access to multidisciplinary expertise.

Abstract
Abstract
Background
The aim of this RCT was to determine whether radiologically inserted gastrostomy (RIG) in children is associated with more complications than percutaneous endoscopic gastrostomy (PEG).
Methods
Children at a single tertiary children's hospital requiring a primary gastrostomy were randomized to PEG or RIG. Patients were followed by assessors blinded to the insertion method. Complications were recorded, assigned a severity score, and analysed by zero-inflated Poisson regression analysis on an intention-to-treat basis, adjusting for length of follow-up.
Results
Over a 3-year period, 214 children were randomized (PEG, 107; RIG, 107), of whom 100 received PEG and 96 RIG. There was no significant difference in the number of complications between PEG and RIG groups (P = 0·875), or in the complication score: patients undergoing RIG had a 1·04 (95 per cent c.i. 0·89 to 1·21) times higher complication score than those who underwent PEG (P = 0·597). Only age had an independent significant effect on complication score, with older patients having a 0·97 (0·95 to 1·00) times lower complication score per year.
Conclusion
PEG and RIG are both safe methods of gastrostomy insertion with a low rate of major complications. Registration number: NCT01920438 (http://www.clinicaltrials.gov).

Abstract
Abstract
Breast cancer is a heterogeneous disease and has subtypes with distinct phenotypic and molecular characteristics. Genetically, 30% of all breast tumors and 80% of the basal-like breast cancer (BLBC) subtype harbor mutations in TP53 and numerous sporadic somatic mutations in other genes. This molecular heterogeneity has posed a challenge in developing safe and effective therapeutic regimens to treat a broad spectrum of breast cancer patients, and discovery of intra-subtype along with inter-subtype heterogeneity has added another layer of complexity for targeted therapies. Based on the analysis of somatic mutation profiles in the BLBC subtype, we identified a wide variety of TP53 missense mutations and thousands of co-existing mutations, which led us to hypothesize that intra-subtype heterogeneity is derived from combinatorial effects of neo-morphic (gain-of-function) activities of different types of missense mutant p53 proteins and complex interplay between specific driver mutations in TP53 and a distinct subset of functionally important co-mutations (or “co-drivers”). We ectopically overexpressed the ten most prevalent missense mutations in TP53 found in breast cancer tumors in non-transformed mammary epithelial cells and examined their cellular functions associated with the hallmarks of cancer. The results showed widely different spectrums of phenotypic changes in cell proliferation, resistance to apoptosis, cell invasion, anoikis resistance and cell polarity. As a proof of concept for the 'co-drivers', we knocked-out PTEN in a non-invasive TP53 mutant cell using the CRISPR and shRNA systems. Inactivation of PTEN in non-invasive TP53-mutant cell increased its invasiveness. TP53 mutations and PTEN deletions are frequent in BLBC patients, who have significantly higher rates of metastasis, recurrence and a lower survival rate than the other subtypes. The absence of three signaling hormone receptors, which can be targeted by specific inhibitors, significantly limits available therapies for the majority of BLBC patients to surgery and cytotoxic chemo/radiotherapies. Combination therapies targeting the driver and co-driver gene associated pathways could be quite promising solutions to treat aggressive breast cancer cases. To address this, we have developed a genome-wide CRISPR based gene knock-out screening approach to test the effect of loss-of-function of individual human genes in clinically important TP53 mutant backgrounds that can promote cancer-like behaviors and identify the combinations of 'TP53 mutation and co-driver pathways' that can be targeted by specific inhibitors.

Abstract
PURPOSE Macrolide antibiotics, erythromycin, in particular, have been linked to the development of infantile hypertrophic pyloric stenosis (IHPS). Our aim was to conduct a systematic review of the evidence of whether post-natal erythromycin exposure is associated with subsequent development of IHPS. METHODS A systematic review of postnatal erythromycin administration and IHPS was performed. Papers were included if data were available on development (yes/no) of IHPS in infants exposed/unexposed to erythromycin. Data were meta-analysed using Review Manager 5.3. A random effects model was decided on a priori due to heterogeneity of study design; data are odds ratio (OR) with 95 % CI. RESULTS Nine papers reported data suitable for analysis; two randomised controlled trials and seven retrospective studies. Overall, erythromycin exposure was significantly associated with development of IHPS [OR 2.45 (1.12-5.35), p = 0.02]. However, significant heterogeneity existed between the studies (I 2 = 84 %, p < 0.0001). Data on erythromycin exposure in the first 14 days of life was extracted from 4/9 studies and identified a strong association between erythromycin exposure and subsequent development IHPS [OR 12.89 (7.67-2167), p < 0.00001]. CONCLUSION This study demonstrates a significant association between post-natal erythromycin exposure and development of IHPS, which seems stronger when exposure occurs in the first 2 weeks of life.

Abstract
Background/Objectives: Whether fat-free mass (FFM) and its components are depleted in eating-disorder (ED) patients is uncertain. Dual energy X-ray absorptiometry (DXA) is widely used to assess body composition in pediatric ED patients; however, its accuracy in underweight populations remains unknown. We aimed (1) to assess body composition of young females with ED involving substantial weight loss, relative to healthy controls using the four-component (4C) model, and (2) to explore the validity of DXA body composition assessment in ED patients. Subjects/Methods: Body composition of 13 females with ED and 117 controls, aged 10–18 years, was investigated using the 4C model. Accuracy of DXA for estimation of FFM and fat mass (FM) was tested using the approach of Bland and Altman. Results: Adjusting for age, height and pubertal stage, ED patients had significantly lower whole-body FM, FFM, protein mass (PM) and mineral mass (MM) compared with controls. Trunk and limb FM and limb lean soft tissue were significantly lower in ED patients. However, no significant difference in the hydration of FFM was detected. Compared with the 4C model, DXA overestimated FM by 5±36% and underestimated FFM by 1±9% in ED patients. Conclusion: Our study confirms that ED patients are depleted not only in FM but also in FFM, PM and MM. DXA has limitations for estimating body composition in individual young female ED patients.

Abstract
INTRODUCTION Esophageal atresia/tracheo-esophageal fistula (EA/TEF) has an incidence of approximately 1:3,500. The incidence of malrotation is thought to be 1:200-500. We attempted to define the incidence of a combination and discuss the implications. METHODS This was a retrospective review of all patients admitted to a single institution with a diagnosis of EA or EA/TEF or TEF between April 1981 and January 2013. Patients were included if the position of the duodeno-jejunal flexure (DJF) was determined by upper GI contrast study (UGIS), surgery or post-mortem. RESULTS Case notes were reviewed for 235 patients. In the EA type A group, 3/28 (11 %; 95 % CI 3.7-27.2 %) had malrotation, significantly higher than the reported incidence of malrotation in the general population (p = 0.0008). All three patients in this group were symptomatic with one patient found to have a volvulus at emergency surgery. In the type C group, 6/196 (3 %, 95 % CI 1.4-6.5 %) had malrotation, significantly higher than the incidence reported for the general population (p = 0.0033) but not significantly different to that of the type A group (p = 0.0878). There were no patients with malrotation identified in any other EA/TEF type. In total, 9/235 (3.8 %; 95 % CI 2.0-7.2 %) patients with EA had malrotation, significantly higher than the 5/1,050 (0.48 %) reported for the general population (p = 0.0002). CONCLUSION There is a high incidence of malrotation in patients with pure EA. In the type A group an attempt to identify the DJF position at gastrostomy siting and/or performance of UGIS in the neonatal period should be undertaken. There should also be a low threshold for UGIS in all EA/TEF patients.

Abstract
Chronic wasting disease (CWD) is an efficiently transmitted, fatal, and progressive prion disease of cervids with an as yet to be fully clarified host range. While outbred domestic cats (Felis catus) have recently been shown to be susceptible to experimental CWD infection, the neuropathologic features of the infection are lacking. Such information is vital to provide diagnostic power in the event of natural interspecies transmission and insights into host and strain interactions in interspecies prion infection. Using light microscopy and immunohistochemistry, we detail the topographic pattern of neural spongiosis (the "lesion profile") and the distribution of misfolded prion protein in the primary and secondary passage of feline CWD (Fel(CWD)). We also evaluated cellular and subcellular associations between misfolded prion protein (PrP(D)) and central nervous system neurons and glial cell populations. From these studies, we (1) describe the novel neuropathologic profile of Fel(CWD), which is distinct from either cervid CWD or feline spongiform encephalopathy (FSE), and (2) provide evidence of serial passage-associated interspecies prion adaptation. In addition, we demonstrate through confocal analysis the successful co-localization of PrP(D) with neurons, astrocytes, microglia, lysosomes, and synaptophysin, which, in part, implicates each of these in the neuropathology of Fel(CWD). In conclusion, this work illustrates the simultaneous role of both host and strain in the development of a unique Fel(CWD) neuropathologic profile and that such a profile can be used to discriminate between Fel(CWD) and FSE.

Abstract
PURPOSE We describe a novel approach to neonatal bladder exstrophy closure that challenges the role of postoperative immobilization and pelvic osteotomy. MATERIALS AND METHODS We reviewed the primary management of bladder exstrophy at our institutions between 2007 and 2011. In particular we compared postoperative management in the surgical ward using epidural analgesia to muscle paralysis and ventilation in the intensive care unit. Clinical outcome measures were time to full feed, length of stay, postoperative complications and redo closure. Cost-effectiveness was also evaluated using hospital financial data. Data are expressed as median (range). Significance was explored by Fisher exact test and unpaired t-test. RESULTS A total of 74 patients underwent primary closure without osteotomy. Successful closure was achieved in 70 patients (95%). A total of 48 cases (65%) were managed on the ward (group A) and 26 (35%) were transferred to the intensive care unit (group B). The 2 groups were homogeneous for gestational age (median 39 weeks, range 27 to 41) and age at closure (3 days, 1 to 152). Complications requiring surgical treatment were noted in 4 patients (8.3%) in group A and 3 (11.5%) in group B (p = 0.609). Length of stay was significantly shorter for the group managed on the ward (11 vs 18 days, p <0.0001). Median costs were $42,732 for patients admitted to the intensive care unit and $16,214 for those admitted directly to the surgical ward (p <0.0001). CONCLUSIONS Primary closure of bladder exstrophy without lower limb immobilization and osteotomy is feasible. Postoperative care on the surgical ward using epidural analgesia results in shorter hospitalization.

Abstract
PURPOSE In our institution, some children routinely receive parenteral nutrition (PN) following surgery for duodenal atresia/stenosis, while others do not. Our aim was to compare growth and infection rate between these two treatment strategies. METHODS This was a retrospective study of all children undergoing surgery for duodenal atresia/stenosis over 7 years. RESULTS Of the 54 children, 19 commenced PN soon after surgery (the 'Initial PN' group). Of the remaining 35 children, 13 (37 %) subsequently required PN (the 'Delayed PN' group). The remaining 22 never received PN (the 'Never PN' group). The proportion of patients experiencing clinically suspected sepsis was higher in those receiving PN ('Initial' plus 'Delayed'; 41 %) compared with those who never received PN (14 %; p = 0.04). The 'Initial PN' and 'Never PN' groups did not show a significant change in weight Z score over time. However, the 'Delayed PN' group showed a significant decrease in weight Z scores from the time of operation to the time of achieving full enteral feeds, and failed to catch up by the time of last follow-up. CONCLUSION Children with duodenal atresia/stenosis can be managed without PN. However, a third of these children subsequently require PN, lose weight centiles, and have a high rate of sepsis.

Abstract
Appendicitis is a common condition in the pediatric population and appendectomy has been the traditional treatment. Both the urgency of the operation and the need for the appendectomy have recently been challenged. In children, this controversy focuses on operative management of perforated appendicitis and appendix abscesses. In adults, the debate has extended to management of nonperforated appendicitis. This review describes the evidence behind these challenges and updates a per-protocol meta-analysis of randomized controlled trials in adults. In the per-protocol meta-analysis, there was no difference between operative versus nonoperative management in failure of treatment. The complication rate was significantly lower in patients treated nonoperatively. However, in the nonoperative group, 10% of patients needed immediate surgery and 17% developed a recurrence during the 1-year follow-up. Overall, 73% of adults with suspected acute appendicitis may not need operative treatment. There are no data in the literature to support nonoperative treatment of acute appendicitis in children.

Abstract
BACKGROUND Addition of glutamine to parenteral nutrition in surgical infants remains controversial. The aim of this trial was to determine whether glutamine supplementation of parenteral nutrition in infants requiring surgery would reduce the time to full enteral feeding and/or decrease the incidence of sepsis and septicaemia. METHODS A prospective double-blind multicentre randomized clinical trial was performed in surgical infants less than 3 months old who required parenteral nutrition. Patients were allocated to treatment or control groups by means of minimization. Infants received either 0·6 g per kg per day alanyl-glutamine (treatment group) or isonitrogenous isocaloric parenteral nutrition (control group) until full enteral feeding was achieved. Primary outcomes were time to full enteral feeding and incidence of sepsis. Cox regression analysis was used to compare time to full enteral feeding, and to calculate risk of sepsis/septicaemia. RESULTS A total of 174 patients were randomized, of whom 164 completed the trial and were analysed (82 in each group). There was no difference in time to full enteral feeding or time to first enteral feeding between groups, and supplementation with glutamine had no effect on the overall incidence of sepsis or septicaemia. However, during total parenteral nutrition (before the first enteral feed), glutamine administration was associated with a significantly decreased risk of developing sepsis (hazard ratio 0·33, 95 per cent confidence interval 0·15 to 0·72; P = 0·005). CONCLUSION Glutamine supplementation during parenteral nutrition did not reduce the incidence of sepsis in surgical infants with gastrointestinal disease.

Abstract
AIM OF THE STUDY The aim of this study was to report incidence and clinical outcomes of recurrent necrotizing enterocolitis (NEC). METHODS Review of infants treated for recurrent episode(s) of NEC at a tertiary Neonatal Surgical Intensive Care Unit over 8 years (January 2002 to February 2011). Demographic, clinical, radiological, and operative data were analyzed and compared using Mann-Whitney or Fisher's exact tests. Data are reported as median (range). RESULTS A total of 212 consecutive infants were referred for surgical evaluation and treatment of NEC (Bell stage II or III). Of these patients, 22 (10%) had suspected recurrent NEC: in 11 of these the primary episode was Bell stage I successfully treated before coming to our institution (suspected recurrent NEC); in the remaining 11, the primary episode was confirmed (Bell stage II or III) NEC successfully treated in our hospital. Birth weight, gestational age at birth, corrected gestational age, weight on admission, gender, need for surgery, stricture, and mortality rates were similar between infants with recurrent NEC and those with a single episode. Long-term parenteral nutrition (PN) dependency (>28 days) was significantly more common following recurrent NEC compared with a single episode. Among the infants with recurrent NEC, medical therapy alone was not successful in the majority (82%) of cases during the first episode and all required surgery during the recurrent episode. CONCLUSION Infants (10%) referred for surgical treatment of NEC develop recurrence of the disease. Surprisingly, these infants have similar mortality and stricture rates to those with a single episode. However, the incidence of long-term PN dependency was significantly increased in those with recurrent episodes of NEC.

Abstract
AIM In ventilator-dependent infants with complex comorbidities, severe gastro-oesophageal reflux (GOR) may contribute to prolonging the period of ventilation. It is often difficult to predict whether antireflux surgery will improve the respiratory status of an infant and assist with weaning off the ventilator. The aim of this study was to review the outcomes in a cohort of ventilator-dependent infants who underwent fundoplication to help wean them off ventilation. METHODS Between January 2006 and December 2010, out of 596 infants who underwent fundoplication for symptoms of GOR, 26 were ventilator dependent before surgery; 13 patients had an emergency fundoplication following an acute life-threatening event (n = 5, 19%) or an acute deterioration of respiratory status (n = 8, 31%). Fundoplication was planned in the rest of the group (n = 13, 50%) with the aim of improving respiratory status and weaning from ventilation. The median age at surgery was 5.8 months (range: 0.8 to 19.4 months). The median weight at surgery was 6.3 kg (range: 4 to 15.1 kg). Data were collected for each infant on comorbidities, pre- and postoperative ventilation status, pre- and postoperative GOR symptoms, and survival. RESULTS All infants underwent a Nissen fundoplication with no intraoperative morbidity or mortality. Of these, 12 infants had a laparoscopic fundoplication; 14 infants had an open fundoplication. Postoperatively, all infants received invasive positive pressure ventilation in the intensive care unit (ICU). All infants were successfully weaned from ventilation. The median time to extubation was 4 days (range: 2 to 18 days). The median postoperative ICU stay was 9 days (range: 3 to 52 days). Of the patients, 9 (34%) had a recurrence of symptoms following fundoplication; 5 (19%) subsequently underwent revision of fundoplication and 1 (3.8%) underwent oesophago-gastric dissociation; and 10 (38%) died within the study period. CONCLUSION In infants with severe GOR, ventilator dependence, and complex comorbidities, fundoplication may be a useful procedure to assist weaning off ventilator dependence. Rates of symptom recurrence, of revision of fundoplication, and of mortality within this cohort were higher than expected. These data reflect the challenges of patient selection in high-risk groups.

Abstract
AIM OF THE STUDY Stomal stenosis is the commonest complication of the antegrade colonic enema (ACE) procedure, reportedly occurring in 25-55% of patients. As such, a simple ACE stopper device (a small silicone plug sited in the ACE conduit between catheterisations) was designed to prevent stenosis. We performed a long-term follow-up study to determine the effectiveness of the stopper device. METHODS A retrospective case note review was performed of all patients who successfully underwent a primary ACE procedure over an 8.5-year period (January 2002 to June 2010). The inclusion criteria were (i) a minimum of 6 months follow-up, (ii) simple appendicostomy, (iii) caecal/colonic flap. In all patients an ACE stopper was sited in the conduit for at least 4 months and removed only for catheterisation. Data are mean±SEM. MAIN RESULTS 38 children were included in our study. Mean age at surgery was 9.6±0.5 years. Surgery was performed in 22 patients for incontinence and in 16 for chronic constipation. 31 underwent an appendicostomy and 7 had a caecal/colonic flap; all received an ACE stopper. The mean follow-up was 2.6±0.3 years. Only 3 patients (8%) developed stomal stenosis. The first occurred 6 months postoperatively, resulting from an ACE stopper which was too small and consequently persistently fell out. This conduit required dilatation. The second occurred at 27 months secondary to a stomal infection and required surgical revision. The third occurred 8 months postoperatively for no obvious cause, and was treated with dilation. 1 patient experienced stomal leakage. CONCLUSION The ACE stopper is a simple yet highly effective method of preventing stomal stenosis. We recommend using the stopper in all ACE patients.

Abstract
INTRODUCTION The purpose of this study was to determine whether, in surgical infants requiring parenteral nutrition (PN), septicaemia due to enterococci or Gram-negative bacilli occurs later than septicaemia due to coagulase-negative staphylococci (CNS). PATIENTS/MATERIAL AND METHODS We retrospectively studied 112 consecutive surgical infants (corrected gestational age up to 3 months) receiving PN for at least 5 days for congenital or acquired intestinal anomalies over a 2-year period (July 2007-June 2009). Data collected included diagnosis, duration of PN, episodes of septicaemia (defined as growth of bacteria from blood culture), and organisms cultured. We compared the time to first occurrence of septicaemia due to CNS with the times to first occurrence of septicaemia due to enterococci, Gram-negative bacilli, or other micro-organisms, using Kruskal-Wallis nonparametric ANOVA test and Dunn's multiple comparisons test. Data are given as median (range). RESULTS 31 patients (28%) had a total of 65 episodes of septicaemia. Septicaemia due to CNS was most common, occurring in 22% of patients, after 17 days (1-239) of PN. Septicaemia due to enteric organisms was less common and occurred significantly later, at 59 (24-103) days for enterococci (p<0.01), and at 55 (30-106) days for Gram-negative bacilli (p<0.05). CONCLUSIONS Septicaemia due to enterococci or Gram-negative bacilli occurs later in the course of PN than septicaemia due to CNS, in surgical infants. This suggests that these infants become more vulnerable to the translocation of enteric micro-organisms after a longer period of parenteral nutrition.

Abstract
AIM OF THE STUDY Intraoperative hypothermia may have a detrimental clinical effect. Preterm infants undergoing laparotomy for necrotizing enterocolitis (NEC) are particularly at risk. We investigated the relationship between intraoperative temperature and morbidity and outcome in infants with NEC. METHODS A review of all laparotomies for NEC (n = 82, 69 infants) performed between Jan 2008 and Jan 2011 in our institution was done. Relationships between intraoperative temperature and intra- and postoperative fluid and blood product requirements, postoperative clinical status (sequential organ failure assessment [SOFA] score) and outcome were determined. Data (mean [range]) were compared using paired t-test and regression analysis. RESULTS Data were available for 52 laparotomies (49 infants). The lowest intraoperative core temperature was significantly lower than the preoperative temperature (peri-op 34.9 °C [31.5-37.0] vs. pre-op 37.0 °C [35.8-38.0]; p < 0.0001). There was a statistically significant inverse relationship between mean intraoperative temperature and intraoperative blood transfusion requirement (p = 0.01). There were no statistically significant relationships between intraoperative temperature and other blood product or volume requirements, postoperative infective complications, change in SOFA score following surgery, length of stay, or mortality. CONCLUSIONS During laparotomy for NEC, there is a significant and profound drop in core temperature. The effect of this on short-term morbidity and long-term outcome (e.g., neurodevelopment) warrants further investigation.

Abstract
AIM OF THE STUDY The aim of this study was to investigate the factors associated with mortality in infants referred for the surgical treatment of advanced necrotizing enterocolitis (NEC). METHODS Retrospective review of all infants with confirmed (Bell stage II or III) NEC treated in our unit during the past 8 years (January 2002 to December 2010). Data for survivors and nonsurvivors were compared using Mann-Whitney test and Fisher's exact test and are reported as median (range). RESULTS Of the 205 infants with NEC, 35 (17%) were medically managed; 170 (83%) had surgery; 66 (32%) infants died; all had received surgery. Survivors and nonsurvivors were comparable for gestational age, birth weight, and gender distribution. Overall mortality was 32%, the highest mortality was in infants with pan-intestinal disease (86%) but remained significant in those with less severe disease (multifocal 39%; focal disease 21%). The commonest cause of mortality was multiple organ dysfunction syndrome and nearly half of the nonsurvivors had care withdrawn. CONCLUSION Despite improvement in neonatal care, overall mortality (32%) for advanced NEC has not changed in 10 years. Mortality is significant even with minimal bowel involvement.

Abstract
PURPOSE The management of Incarcerated Inguinal Hernia (IIH) in children is challenging and may be associated with complications. We aimed to compare the outcomes of laparoscopic vs. open repair of IIH. METHODS With institutional ethical approval (09SG13), we reviewed the notes of 63 consecutive children who were admitted to a single hospital with the diagnosis of IIH between 2000 and 2008. Data are reported as median (range). Groups were compared by chi-squared or t-tests as appropriate. RESULTS · Open repair (n=35): There were 21 children with right and 14 with left IIH. 2 patients also had contralateral reducible inguinal hernia. Small bowel resection was required in 2 children. · Laparoscopic repair (n=28): All children had unilateral IIH (19 right sided, 9 left sided). 15 children (54%) with no clinical evidence of contralateral hernia, had contralateral patent processus vaginalis at laparoscopy, which was also repaired. The groups were similar with regard to gender, age at surgery, history of prematurity, interval between admission and surgery, and proportion of patients with successful preoperative manual reduction. However, the duration of operation was longer in the laparoscopy group (p=0.01). Time to full feeds and length of hospital stay were similar in both groups. Postoperative follow-up was 3.5 months (1-36), which was similar in both groups. 5 patients in the group undergoing open repair had serious complications: 1 vas transaction, 1 acquired undescended testis, 2 testicular atrophy and 1 recurrence. The laparoscopic group had a single recurrence. CONCLUSION Open repair of incarcerated inguinal hernia is associated with serious complications. The laparoscopic technique appears safe, avoids the difficult dissection of an oedematous sac in the groin, allows inspection of the reduced hernia content and permits the repair of a contralateral patent processus vaginalis if present.

Abstract
INTRODUCTION Ganglioneuroma (GN), the benign form of peripheral neuroblastic tumour, is often asymptomatic and the diagnosis can be incidental. Our aim was to evaluate the incidence of complications after surgical treatment following diagnosis of this tumour. MATERIAL AND METHODS 24 consecutive children were diagnosed with GN in our centre between January 1989 and December 2009. All patients had negative urinary catecholamines and/or biopsy confirming the diagnosis of GN. Data are reported as mean ± SD. RESULTS Age at diagnosis was 73 ± 43 months. The most common presentation was respiratory symptoms and/or abdominal pain; 9 (38%) patients were asymptomatic. Tumour location was in the chest (n=14), abdomen (n=7), or pelvis (n=3). 23 children (9 asymptomatic) were operated on; 1 child with a thoracic mass did not undergo surgery because of severe neurological impairments from birth unrelated to GN. 13 children (4 asymptomatic) had a thoracotomy, 8 children (4 asymptomatic) had laparotomy, and 2 (1 asymptomatic) underwent perineal resection. A macroscopically complete surgical excision was performed in 17 cases (74%) and a macroscopically near-complete excision in 6 (26%). At histological examination, resection margins contained tumour in 10 patients (43%) and were free of tumour in the remaining 13 (57%). 7 children (30%) had complications after surgery including 3 patients with Horner's syndrome (which persisted in 2), 1 with chylothorax, 1 with pneumothorax, 1 with pain in the arm, and 1 who developed adhesive intestinal obstruction. 2 children received adjuvant chemotherapy. We re-evaluated the histology specimens according to the International Neuroblastoma Pathology Classification and found that the diagnosis of GN was confirmed in 20 cases (83%), while intermixed ganglioneuroblastoma (iGNB) was diagnosed in 4 patients (17%). At 33.5 ± 40 months (range 1-137) follow-up, all 24 patients, including the child not operated on and the children with incomplete resection or iGNB, are alive with no tumour progression or recurrence. CONCLUSIONS GN excision is associated with postoperative complications which can be persistent and may affect the quality of life of survivors. In our series we did not observe tumour progression in spite of incomplete excision. The rationale for GN excision should be revisited.

Abstract
Epithelia are sheets of cells that are dynamically remodelled by cell division and cell death during development. Here we describe the cell shapes and packings as networks of polygons: stable and stationary network configurations obey force balance and are represented as local minima of a potential function. We characterize the physical properties of this vertex model, including the set of ground states, and the energetics of topological rearrangements. We furthermore discuss a quasistatic description of cell division that allows us to study the mechanics and dynamics of tissue remodelling during growth. The biophysics of cells and their rearrangements can account for the morphology of cell packings observed in experiments.

Abstract
INTRODUCTION Bone marrow-derived circulating granulocyte and macrophage progenitor cells can contribute to the regeneration of ischemic tissue. Mobilization after heart or brain ischemia is well established, but it is unclear if this occurs after intestinal ischemia-reperfusion injury. Our aim was to evaluate bone marrow granulocyte-macrophage proliferation and the possible beneficial effect of recombinant human granulocyte-colony stimulating factor (rhG-CSF) in a model of intestinal ischemia-reperfusion. MATERIAL AND METHODS After animal committee approval, anesthetized adult rats were divided into groups (n=4 per group) as follows: (i) control [C], (ii) 60 min intestinal ischemia [I], (iii) 60 min intestinal ischemia+360 min reperfusion [IR], (iv) 420 min sham operation [SH]. At sacrifice, bone marrow was removed, erythrocytes lysed and 1 50 000 nucleated cells plated in triplicate in 35 mm Petri dishes containing methylcellulose (MethoCult). After 11 days, granulocyte-macrophage colony-forming units (CFU-GM) were counted. In addition, to determine whether rhG-CSF injection stimulates progenitor cell activation, two further groups were studied: (v) 60 min intestinal ischemia+360 min reperfusion with injection of 50 microg/kg rhG-CSF at reperfusion [IR-G]; (vi) 420 min sham with rhG-CSF injected at 60 min [SH-G]. Data are expressed as median, range and IQR and compared using one-way ANOVA with Tukey's post-hoc test. RESULTS Neither sham operation nor ischemia alone influenced the activation of bone marrow. However, IR caused a significant increase in bone marrow activation compared to control animals (p<0.01), ischemic animals (p<0.01) and sham operated animals (p<0.05). Administered at a dose of 50 microg/kg, which is commonly used in animal studies, rhG-CSF had no effect on bone marrow activation, and did not augment the effects of ischemia-reperfusion. At a higher dose (100 microg/kg), however, rhG-CSF resulted in the mortality of IR animals. CONCLUSIONS Intestinal ischemia-reperfusion injury causes proliferation of bone marrow granulocyte-macrophage progenitors which contribute to long-term repair. This phenomenon is not augmented by the administration of exogenous rhG-CSF.

Abstract
Considerable advances have been achieved in paediatric surgery during the last two decades, which can be partly ascribed to a better understanding of the physiological response to operations and the use of that knowledge to decrease the metabolic response where appropriate. Alongside this, minimally invasive surgery is now well established for many surgical conditions in the neonate, infant and child. The metabolic response to surgery differs in neonates to that seen in adults: there is a small increase in oxygen consumption and resting energy expenditure immediately after surgery with a return to normal levels by 12-24 h. The increase in resting energy expenditure is significantly greater in infants undergoing a major operation than in those subjected to a minor procedure. The limited increase in energy expenditure may be due to diversion of energy from growth to tissue repair. There are limited data available on older children, but they appear to have a different pattern of postoperative resting energy expenditure. There is a fall in the early postoperative period, similar to data collected in adults, but no late hypermetabolism. Protein metabolism mirrors energy expenditure and contributes to the overall changes observed. Various factors affect the magnitude of the response. It seems that in children intraoperative thermoregulation and metabolism are significant drivers of many of the postoperative changes. Minimally invasive surgery may maintain preoperative metabolic processes by altering the postoperative processes on a physiological level or by maintaining thermoregulation in children. The mechanism and potential benefit of these observations need further investigation.

Abstract
5594 Background: To compare the efficacy of pyridoxine versus placebo in the prevention of palmar-plantar erythrodysesthesia (PPE) and on quality of life (QOL) in patients treated with pegylated liposomal doxorubicin hydrochloride for ovarian, breast, or endometrial cancer. Methods: All patients received pegylated liposomal doxorubicin hydrochloride 40 mg/m2 IV q 4 weeks over 1 hour every 28 days for a maximum of 6 cycles. Patients received pyridoxine 100 mg (group A) by mouth or placebo (group B) twice daily. Nurses conducted standard PPE education for all patients. Patients with Grade 2 or 3 PPE that persisted despite dose reductions/delays were unblinded, and were given pyridoxine if taking placebo. Patients completed the Functional Assessment of Cancer Therapy (FACT) assessment tool. Analyses were conducted by group and comparisons were also made between patients who experienced grade 2/3 PPE versus grade 0/1. Chi-square or Fisher's exact test were used. Results: Thirty-four patients were enrolled with 18 randomized to group A and 16 to group B. Mean age was 64 years (SD=9.6; range 45–81 years). Five patients (group A, 3; group B, 2) were unevaluable (due to pegylated liposomal doxorubicin hydrochloride reaction during first chemotherapy cycle). Overall 15/29 (52%) patients had incidence of PPE (all grades), with 10/29 (34%) having grade 2/3 events (no grade 4 events observed). In group A, 8/15 (53%) patients had a PPE event and 7/14 (50%) in group B; p=0.857. For grade 2/3 events, there was no difference as 6/15 (40%) occurred in group A and 4/14 (29%) in group B; p=0.70. There were no differences in global or domain QOL scores between those patients with Grade 2/3 PPE versus Grade 0/1. Less than half [4/10 (40%)] of patients with Grade 2/3 PPE reported being bothered by side effects of pegylated liposomal doxorubicin hydrochloride treatment. Conclusions: As administered in this study, pyridoxine did not prevent PPE in patients treated with pegylated liposomal doxorubicin hydrochloride. Quality of life differences were not observed; however, not all patients with PPE reported being bothered by side effects of pegylated liposomal doxorubicin hydrochloride treatment. Pyridoxine is not indicated for prevention of PPE during chemotherapy. [Table: see text] [Table: see text]

Abstract
AIM OF THE STUDY The effects on gastric motility following Nissen fundoplication in children are poorly documented. Some paediatric surgeons advocate additional procedures at the same time as fundoplication, such as a pyloroplasty, to enhance gastric emptying. The aim of this study was to determine whether laparoscopic Nissen fundoplication without pyloroplasty affects gastric emptying. METHODS Gastric emptying was measured before laparoscopic Nissen fundoplication in 8 children after ingestion of a standardised volume of milk for age mixed with 150 mg of (13)C-octanoic acid. None of the patients had a gastrostomy insertion at the time of fundoplication and 2 patients had neurological impairment. Breath samples were collected by breathing into a mask at baseline and every 15 minutes up to 3 hours, and were analysed for (13)CO (2)/ (12)CO (2) ratio by mass spectrometry. Gastric emptying time (t (1/2)) was derived from the curve of (13)CO (2)/ (12)CO (2) ratio against time. The test was repeated in 6 children following Nissen fundoplication at the time of full feeds. Data are reported as mean +/- SD and were analysed by the Mann-Whitney test. RESULTS AND CONCLUSIONS There were 4 males and 4 females; mean age at surgery was 3.3 +/- 3.0 years. Mean gastric emptying time was 59 +/- 17 min prior to laparoscopic Nissen fundoplication and 45 +/- 4 min following surgery (p = 0.03). Gastric emptying was accelerated in all except one patient. Gastric emptying for liquids is accelerated following Nissen fundoplication in children. Procedures aimed at improving gastric emptying time such as pyloroplasty or pyloromyotomy might not be justified at the time of laparoscopic Nissen fundoplication.

Abstract
INTRODUCTION A neonatal rat model of necrotizing enterocolitis (NEC) is useful to investigate this devastating and obscure disease. The aim of this study was to assess a neonatal rat model of NEC to evaluate whether the histological appearance of the damaged intestine could be predicted by the clinical behaviour of the animals and the macroscopic appearance of the gut. MATERIALS AND METHODS Neonatal rats were delivered at term and assigned either to a control group consisting of breastfeeding and no stress factors, or to a NEC group in which NEC was induced by gavage feeding + hypoxia + oral lipopolysaccharide (4 mg/kg/day once daily for the first 2 days of life). Clinical status was assessed on day 4 using a clinical sickness score (general appearance, response to touch, natural activity, body colour; 0 - 3 for each variable). Neonatal rats were sacrificed at 4 different time points: day 1, day 2, day 3, and day 4. At sacrifice, a macroscopic assessment of the gut was performed using a new scoring system based on: colour (0 - 2), consistency (0 - 2) and degree of dilatation (0 - 2). The resected gut was stained with haematoxylin/eosin, and evaluated microscopically by 2 independent blinded scorers, including a consultant histopathologist. The histology results were used to validate the macroscopic gut assessment. Results were compared by ANOVA and linear regression analysis. Ethics Committee and Home Office approvals were obtained. RESULTS In the control group NEC was not present either macroscopically or histologically. The clinical sickness score was higher in the NEC group (median = 4.5; range = 2 - 6) compared to controls (median = 0; range = 0 - 1; p < 0.0001). In the NEC group the macroscopic appearance (from day 2) and histological score (from day 1) increased significantly (p < 0.0001) and were strongly correlated (r (2) = 0.74, p < 0.0001). CONCLUSIONS The clinical behaviour and macroscopic appearance of the intestine are valid tools to assess gut damage in our neonatal rat model of NEC. This allows future studies that are not exclusively based on histology.

Abstract
AIM E-selectin is an important mediator of leukocyte-endothelial adhesion. It is expressed on activated endothelium, and shed into the circulation in its soluble form. In babies with necrotising enterocolitis (NEC), increased intestinal expression of E-selectin has been associated with multiple organ failure and an adverse outcome. The aim of this study was to determine whether increased circulating soluble E-selectin (sE-selectin) was associated with a worse prognosis. METHODS With ethical approval, plasma samples from 20 infants with Bell stage II and III NEC were analysed. Both pre- and postoperative samples were available in 6 infants. The severity of illness was assessed using a sequential organ failure assessment score (SOFA) specifically designed for use in NEC. Plasma concentration of sE-selectin was determined by ELISA. Data, which were not normally distributed, were compared by Spearman's rank correlation coefficient and Wilcoxon signed rank test. RESULTS Plasma sE-selectin was strongly negatively correlated with corrected gestational age at the time of sampling (r = - 0.425, p = 0.006). There was no association between plasma sE-selectin and outcome (death or survival to discharge), severity of intestinal disease (focal, multifocal or pan-intestinal), or SOFA score. Surgery for suspected perforation, however, caused a significant elevation in sE-selectin levels (p = 0.031). CONCLUSIONS Plasma sE-selectin, a described marker of endothelial activation, is increased following surgery for NEC. However, prematurity appears to be the cause of an increase in sE-selectin level, confounding the potential use of sE-selectin levels as a predictor of severity of illness in NEC.

Abstract
AIMS To establish if a relationship exists between the prescribing costs of diabetes treatments and the achievement of Quality and Outcome Framework DM6 standards of glycaemic control. METHODS A retrospective cross-sectional study of all 92 primary care organizations in the north of England comparing net ingredient cost of diabetes treatments, corrected for diabetic population, with the percentage of patients achieving HbA(1c) < 7.4% (Quality and Outcome Framework DM6 indicator). RESULTS The overall net ingredient cost for diabetes treatments varies from pound 225 to pound 382 per person per year. On regression analysis, expenditure on all diabetes treatments, on glitazones or on blood glucose test strips have no significant impact upon the percentage of people achieving an HbA(1c) < 7.4%. There is an inverse relationship between spending on analogue insulins and target achievement (r = -0.08, P = 0.001). CONCLUSIONS At primary care organization level, there is no association between weighted expenditure on diabetes treatments and achievement of glycaemic control targets. Although there are limitations to what can be inferred from analyses of this type, these data support a judicious and carefully directed approach to the use of newer, more expensive treatments until clear evidence of added benefit is forthcoming.

Abstract
OBJECTIVE To evaluate the effectiveness of a structured group education programme on biomedical, psychosocial, and lifestyle measures in people with newly diagnosed type 2 diabetes. DESIGN Multicentre cluster randomised controlled trial in primary care with randomisation at practice level. SETTING 207 general practices in 13 primary care sites in the United Kingdom. PARTICIPANTS 824 adults (55% men, mean age 59.5 years). INTERVENTION A structured group education programme for six hours delivered in the community by two trained healthcare professional educators compared with usual care. MAIN OUTCOME MEASURES Haemoglobin A(1c) levels, blood pressure, weight, blood lipid levels, smoking status, physical activity, quality of life, beliefs about illness, depression, and emotional impact of diabetes at baseline and up to 12 months. MAIN RESULTS Haemoglobin A(1c) levels at 12 months had decreased by 1.49% in the intervention group compared with 1.21% in the control group. After adjusting for baseline and cluster, the difference was not significant: 0.05% (95% confidence interval -0.10% to 0.20%). The intervention group showed a greater weight loss: -2.98 kg (95% confidence interval -3.54 to -2.41) compared with 1.86 kg (-2.44 to -1.28), P=0.027 at 12 months. The odds of not smoking were 3.56 (95% confidence interval 1.11 to 11.45), P=0.033 higher in the intervention group at 12 months. The intervention group showed significantly greater changes in illness belief scores (P=0.001); directions of change were positive indicating greater understanding of diabetes. The intervention group had a lower depression score at 12 months: mean difference was -0.50 (95% confidence interval -0.96 to -0.04); P=0.032. A positive association was found between change in perceived personal responsibility and weight loss at 12 months (beta=0.12; P=0.008). CONCLUSION A structured group education programme for patients with newly diagnosed type 2 diabetes resulted in greater improvements in weight loss and smoking cessation and positive improvements in beliefs about illness but no difference in haemoglobin A(1c) levels up to 12 months after diagnosis.

Abstract
OBJECTIVES To assess the cost-effectiveness of a brief physiotherapy pain management approach using cognitive-behavioural principles (Solution-Finding Approach) when compared with a commonly used traditional method of physical therapy (McKenzie Approach). METHODS Economic evaluation conducted alongside a randomized trial. The study related incremental differences in costs and benefits associated with the Solution Finding and McKenzie approaches over 12 months. Costs were measured in UK pounds sterling. Benefit was measured as health-related quality of life using the EQ-5D, which was used to estimate patient-specific quality adjusted life years (QALYs). RESULTS The McKenzie treatment required, on average, one extra physiotherapist visit (4.15 vs 3.10). Over a 12-month period, Solution Finding was associated with a lower per patient cost of pound-24.4 (95% CI pound-49.6 to 0.789 pounds). The mean difference in QALYs between the two groups was -0.020 (95% CI -0.057 to 0.017); favouring those receiving McKenzie. Relating incremental mean costs and QALYs gave an incremental cost effectiveness ratio of 1220 pounds (-24.4/-0.020) suggesting the McKenzie treatment is cost effective. CONCLUSIONS Results suggest that the additional cost associated with the McKenzie treatment when compared with the Solution Finding Approach may be worth paying, given the additional benefit the approach seems more likely to provide. Further research is needed to assess the extent to which the difference in physiotherapy visits between the two strategies is generalizable to other treatment settings.

Abstract
Abstract
Background
This study aims to establish the risk of developing a metachronous contralateral inguinal hernia (MCIH) following open repair of a unilateral inguinal hernia in children.
Methods
A systematic review was performed using a defined search strategy. Studies in which children undergoing open repair of a unilateral inguinal hernia without contralateral exploration and who were followed up for MCIH development were included.
Results
Of 5937 titles and abstracts screened, 154 full-text articles were identified for review; 49 papers were analysed with data on 22 846 children. The incidence of MCIH was 7·2 per cent overall, 6·9 per cent in boys and 7·3 per cent in girls (P = 0·381). Children with a left-sided inguinal hernia had a significantly higher risk of developing a MCIH than those with a right-sided hernia (10·2 versus 6·3 per cent respectively; P < 0·001).
Conclusion
Overall, in both boys and girls, 14 contralateral explorations are required to prevent one metachronous hernia. The risk of developing a MCIH appears unchanged in early childhood, with a slight reduction after 12 years of age. Children with a left-sided hernia have the greatest risk of developing a contralateral hernia, but ten explorations are still required to prevent one metachronous hernia. Most MCIHs occur in the first 5 years after unilateral inguinal hernia repair.

Abstract
OBJECTIVE To determine whether a new starch offers better short-term metabolic control than uncooked cornstarch in patients with glycogen storage diseases (GSDs). STUDY DESIGN A short-term double-blind cross-over pilot study comparing uncooked physically modified cornstarch (WMHM20) with uncooked cornstarch in patients with GSD types Ia, Ib and III. Twenty-one patients (ages 3-47, 9 female) were given 2 g/kg cornstarch or WMHM20 mixed in water. Blood glucose, lactate and insulin, and breath hydrogen and (13)CO2 enrichment were measured, at baseline and after each load. The hourly biochemical evaluations terminated when blood glucose was < or = 3.0 mmol/L, when the study period had lasted 10 h or when the patient wished to end the test. The alternative starch was administered under similar trial conditions a median of 10 days later. RESULTS The median starch load duration was 9 h for WMHM20 versus 7 h for cornstarch. Glucose decreased more slowly (p = 0.05) and lactate was suppressed faster (p = 0.17) for WMHM20 compared with cornstarch. Peak hydrogen excretion was increased (p = 0.05) when cornstarch was taken. CONCLUSION These data indicate longer duration of euglycaemia and better short-term metabolic control in the majority of GSD patients with WMHM20 compared to cornstarch.
