Abstract
BACKGROUND Increasing evidence links early life residential exposure to natural urban environmental attributes and positive health outcomes in children. However, few studies have focused on their protective effects on the risk of autism spectrum disorder (ASD). The aim of this study was to investigate the associations of neighborhood greenspace, and active living environments during pregnancy with ASD in young children (≤6 years). METHODS We conducted a population-based matched case-control study of singleton term births in Ontario, Canada for 2012-2016. The ASD and environmental data was generated using the Ontario Autism Spectrum Profile, the Better Outcomes Registry & Network Ontario, and Canadian Urban Environmental Health Research Consortium. We employed conditional logistic regressions to estimate the odds ratio (OR) between ASD and environmental factors characterizing selected greenspace metrics and neighborhoods conducive to active living (i.e., green view index (GVI), normalized difference vegetation index (NDVI), tree canopy, park proximity and active living environments index (ALE)). RESULTS We linked 8643 mother-child pairs, including 1554 cases (18%). NDVI (OR 1.034, 0.944-1.024, per Inter Quartile Range [IQR] = 0.08), GVI (OR 1.025, 95% CI 0.953-1.087, per IQR = 9.45%), tree canopy (OR 0.992, 95% CI 0.903-1.089, per IQR = 6.24%) and the different categories of ALE were not associated with ASD in adjusted models for air pollution. In contrast, living closer to a park was protective (OR 0.888, 0.833-0.948, per 0.06 increase in park proximity index), when adjusted for air pollution. CONCLUSIONS This study reported mixed findings showing both null and beneficial effects of green spaces and active living environments on ASD. Further investigations are warranted to elucidate the role of exposure to greenspaces and active living environments on the development of ASD.

Abstract
AIMS Pre-gestational diabetes mellitus (PGDM) is associated with adverse outcomes. We aimed to examine pregnancies affected by PGDM; report on these pregnancy outcomes and compare outcomes for patients with type 1 versus type 2 diabetes mellitus; compare our findings to published Irish and United Kingdom (UK) data and identify potential areas for improvement. METHODS Between 2016 and 2018 information on 679 pregnancies from 415 women with type 1 Diabetes Mellitus and 244 women with type 2 diabetes was analysed. Data was collected on maternal characteristics; pregnancy preparation; glycaemic control; pregnancy related complications; foetal and maternal outcomes; unscheduled hospitalisations; congenital anomalies and perinatal deaths. RESULTS Only 15.9% of women were adequately prepared for pregnancy. Significant deficits were identified in availability and attendance at pre-pregnancy clinic, use of folic acid, attaining appropriate glycaemic targets and appropriate retinal screening. The majority of pregnancies (n = 567, 83.5%) resulted in a live birth but the large number of infants born large for gestational age (LGA) (n = 280, 49.4%), born prematurely <37 weeks and requiring neonatal intensive care unit (NICU) admission continue to be significant issues. CONCLUSIONS This retrospective cohort study identifies multiple targets for improvements in the provision of care to women with pre-gestational DM which are likely to translate into better pregnancy outcomes.

Abstract
AIMS The purpose of this study was to identify the number of pregnancies affected by pre-gestational diabetes in the Republic of Ireland; to report on pregnancy outcomes and to identify areas for improvement in care delivery and clinical outcomes. METHODS Healthcare professionals caring for women with pre-gestational diabetes during pregnancy were invited to participate in this retrospective study. Data pertaining to 185 pregnancies in women attending 15 antenatal centres nationally were collected and analysed. Included pregnancies had an estimated date of delivery between 1 January and 31 December 2015. RESULTS The cohort consisted of 122 (65.9%) women with Type 1 diabetes and 56 (30.3%) women with Type 2 diabetes. The remaining 7 (3.8%) pregnancies were to women with maturity-onset diabetes of the young (MODY) (n = 6) and post-transplant diabetes (n = 1). Overall women were poorly prepared for pregnancy and lapses in specific areas of service delivery including pre-pregnancy care and retinal screening were identified. The majority of pregnancies 156 (84.3%) resulted in a live birth. A total of 103 (65.5%) women had a caesarean delivery and 58 (36.9%) infants were large for gestational age. CONCLUSIONS This audit identifies clear areas for improvement in delivery of care for women with diabetes in the Republic of Ireland before and during pregnancy.

Abstract
INTRODUCTION Mothers with diabetes face unique challenges associated with breastfeeding initiation and maintenance. Antenatal breastmilk expression (BME) may be suggested to mothers, including mothers with diabetes, to improve breastfeeding, maternal, and infant outcomes postpartum. However, there have been few evaluations of the potential harms and benefits of this practice. The objective of our scoping review will be to broadly examine the literature describing maternal and infant outcomes of antenatal BME. METHODS AND ANALYSIS This scoping review will address the research question: 'Among women who engaged in antenatal BME, what maternal and infant outcomes have been evaluated?' A search of published and unpublished studies available in English will be conducted in February 2020 using the following databases: Medline (OVID), Embase (OVID), CINAHL (EBSCOHost), and Cochrane Database of Systematic Reviews (OVID). A search of the British Library E-Theses Online Services (EThOS) database and OpenGrey will be conducted to identify relevant grey literature. This scoping review will use a five-step framework to guide the selection, extraction, and analysis of eligible studies. Clinical consultation will be included as a sixth step to our methodology. Literature reporting on the effect of antenatal BME on maternal and infant outcomes, breastfeeding initiation and duration, and the experiences of women who have engaged in the practice will be considered. The data will be summarised with attention paid to high-risk obstetrical populations such as women with diabetes. Our results will be reported as outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. ETHICS AND DISSEMINATION Research ethics board approval will not be required due to the nature of the study's methodology. The results of this review will be disseminated through peer-reviewed publication and presentation at relevant conferences. TRAIL REGISTRATION NUMBER Open Science Framework (osf.io/gfp2q).

Abstract
Introduction: Preterm birth is a major global health concern, contributing to 35% of all neonatal deaths in 2016. Given the importance of accurately ascertaining estimates of preterm birth and in light of current limitations in postnatal gestational age (GA) estimation, novel methods of estimating GA postnatally in the absence of prenatal ultrasound are needed. Previous work has demonstrated the potential for metabolomics to estimate GA by analyzing data captured through routine newborn screening. Areas covered: Circulating analytes found in newborn blood samples vary by GA. Leveraging newborn screening and demographic data, our group developed an algorithm capable of estimating GA postnatally to within approximately 1 week of ultrasound-validated GA. Since then, we have built on the model by including additional analytes and validating the model's performance through internal and external validation studies, and through implementation of the model internationally. Expert opinion: Currently, using metabolomics to estimate GA postnatally holds considerable promise but is limited by issues of cost-effectiveness and resource access in low-income settings. Future work will focus on enhancing the precision of this approach while prioritizing point-of-care testing that is both accessible and acceptable to individuals in low-resource settings.

Abstract
This study sought to evaluate the performance of metabolic gestational age estimation models developed in Ontario, Canada in infants born in Bangladesh. Cord and heel prick blood spots were collected in Bangladesh and analyzed at a newborn screening facility in Ottawa, Canada. Algorithm-derived estimates of gestational age and preterm birth were compared to ultrasound-validated estimates. 1036 cord blood and 487 heel prick samples were collected from 1069 unique newborns. The majority of samples (93.2% of heel prick and 89.9% of cord blood) were collected from term infants. When applied to heel prick data, algorithms correctly estimated gestational age to within an average deviation of 1 week overall (root mean square error = 1.07 weeks). Metabolic gestational age estimation provides accurate population-level estimates of gestational age in this data set. Models were effective on data obtained from both heel prick and cord blood, the latter being a more feasible option in low-resource settings. Complications from preterm birth are the leading cause of death among children under five. Ultrasounds are routinely used in wealthy countries to track babies' development. In countries with limited resources, however, ultrasounds are rare, making it harder to estimate how many children are born prematurely. Blood tests may offer a way to determine whether a newborn was born too early when ultrasounds are not available. Many countries already require clinicians to collect a drop of blood from newborns via a heel-prick or from their umbilical cord. Testing these blood spots identifies babies at risk of rare conditions so they can receive prompt treatment. Chemicals in the blood vary depending on how long the newborn spent growing in its mother’s womb. Scientists have developed a mathematical formula that can estimate a baby’s gestational age based on these chemicals. Using blood spots to estimate gestational age worked well when this strategy was tested in Canada, a high-income country. More tests are needed to determine if it works in low-income countries. Now, Murphy et al. show their blood spot-testing strategy also reliably predicts the gestational age of babies in Matlab, Bangladesh. In the experiments, blood spots were collected from 1,069 newborns. This included 1,036 cord blood samples and 487 heel prick samples. Nearly all the samples came from full-term infants. A mathematical model estimated the infants' gestational age to within an average of one week of their true age when applied to heel-prick blood samples and to within two weeks of the baby’s true gestational age 94% of the time. The model also provided reliable estimates of babies’ gestational ages when cord blood samples were tested, which is useful as the Bangladeshi parents were more comfortable with this method of blood collection. Using this strategy to estimate how many babies are born too early in low-income countries may help the countries develop strategies to reduce preterm births. The estimates might also help identify preterm babies who need special care.

Abstract
Human papillomavirus is among the most common sexually transmitted infections in the world. Newcomers, defined in Canada as foreign-born individuals who are either immigrants or refugees, but may also include students and undocumented migrants, face numerous barriers to HPV vaccination. This study sought to understand, from the perspective of healthcare providers, barriers and facilitators to HPV vaccination, and recommendations to improve HPV vaccine uptake among newcomers. Semi-structured interviews were conducted with 10 healthcare providers between March and April 2018. Data were analyzed at the manifest level using a Qualitative Content Analysis approach. Categories of barriers to vaccination included: access, communication, knowledge, culture, and provider-related factors. Facilitators included targeted health promotion; understanding the relevance of HPV vaccination; trusting the healthcare system; and cultural sensitivity. Two overarching recommendations were to publicly fund the HPV vaccine, and enhance language- and culturally-appropriate health promotion activities. Further research should explore informational desires and needs from the perspective of newcomers to inform strategies to promote equitable HPV vaccine coverage.

Abstract
Background The Ottawa Ankle Rules, Ottawa Knee Rule, and Canadian C-Spine Rule—together known as The Ottawa Rules—are a set of internationally validated clinical decision rules developed to decrease unnecessary diagnostic imaging in the emergency department. In this study, we sought to develop and evaluate the use of a mobile app version of The Ottawa Rules. Objective The primary objective of this study was to determine acceptability of The Ottawa Rules app among emergency department clinicians. The secondary objective was to evaluate the effect of publicity efforts on uptake of The Ottawa Rules app. Methods The Ottawa Rules app was developed and publicly released for free on iOS and Android operating systems in April 2016. Local and national news and academic media coverage coincided with app release. This study was conducted at a large tertiary trauma care center in Ottawa, Canada. The study was advertised through posters and electronically by email. Emergency department clinicians were approached in person to enroll via in-app consent for a 1-month study during which time they were encouraged to use the app when evaluating patients with suspected knee, foot, or neck injuries. A 23-question survey was administered at the end of the study period via email to determine self-reported frequency, perceived ease of use of the app, and participant Technology Readiness Index scores. Results A total of 108 emergency department clinicians completed the study including 42 nurses, 33 residents, 20 attending physicians, and 13 medical students completing emergency department rotations. The median Technology Readiness Index for this group was 3.56, indicating a moderate degree of openness for technological adoption. The majority of survey respondents indicated favorable receptivity to the app including finding it helpful to applying the rules (73/108, 67.6%), that they would recommend the app to colleagues (81/108, 75.0%), and that they would continue using the app (73/108, 67.6%). Feedback from study participants highlighted a desire for access to more clinical decision rules and a higher degree of interactivity of the app. Between April 21, 2016, and June 1, 2017, The Ottawa Rules app was downloaded approximately 4000 times across 89 countries. Conclusions We have found The Ottawa Rules app to be an effective means to disseminate the Ottawa Ankle Rules, Ottawa Knee Rule, and Canadian C-Spine Rule among all levels of emergency department clinicians. We have been successful in monitoring uptake and access of the rules in the app as a result of our publicity efforts. Mobile technology can be leveraged to improve the accessibility of clinical decision tools to health professionals.

Abstract
OBJECTIVES The incidence of seroma after thyroidectomy has been reported between 1.3% and 7%. We hypothesised that a flapless thyroidectomy technique would reduce the incidence of seroma. DESIGN Observational case-control study with comparison between retrospective cohort of patients undergoing thyroidectomy with raising of conventional skin flaps and prospective cohort undergoing flapless surgery. SETTING Academic Teaching Hospital. PARTICIPANTS Hundred and seventy-five consecutive patients undergoing thyroidectomy performed by a single surgeon. After the first 85 cases, a change in practice took place, from raising of conventional skin flaps to performing flapless surgery wherever feasible. MAIN OUTCOME MEASURES Occurrence of postoperative seroma, defined as central neck swelling in postoperative period, confirmed by aspiration of serous fluid, and other complications. RESULTS Eight patients who underwent concomitant lateral (jugular) neck dissection were excluded. Among the remaining 167 patients, there were eight seromas (5%). Following the change in practice to flapless surgery, there was a significant reduction in the incidence of seroma (P = 0.025). There was no significant difference in other complications (haematoma; recurrent laryngeal nerve injury; and hypocalcaemia). Among the entire group, the association between seroma and flapless surgery tended towards significance (P = 0.07). Other variables studied, including use of drain and concomitant central compartment neck dissection, had no effect on seroma. CONCLUSION Flapless technique for thyroid surgery may reduce the incidence of postoperative seroma.

Abstract
BACKGROUND AND AIM A select group of children with short bowel syndrome (SBS) and intestinal failure-associated liver disease (IFALD) fulfill the criteria for isolated liver transplantation (iLTx). Long-term results in this group of patients have not been reported. METHODS A retrospective study of the medical records of 8 survivors of 14 children who underwent iLTx for SBS and IFALD from 1998 to 2005, managed by a multidisciplinary intestinal rehabilitation team at our institution. RESULTS Median follow-up is 107.5 months (range 89-153 months). Five of 8 children were weaned from parenteral nutrition (PN) to enteral nutrition (EN) in a median of 10 months after iLTx (range 3-32 months). Three of 5 children were subsequently weaned from EN to full oral feeding in 13, 24, and 53 months after stopping PN, whereas the remaining 2 are still receiving EN 118 and 74 months after stopping PN. These 5 children maintain their weight median z scores with a median increase of 1.59 (range 1.24-1.79) compared with the pretransplant z score, whereas the height z scores show fluctuations through the years with a median change of 0.12 (range -0.29 to 0.36). The other 3 of 8 children developed progressive intestinal failure; 2 underwent isolated small bowel transplantation 112 and 84 months after iLTx and the third is receiving PN. CONCLUSIONS Children with SBS and IFALD who have the potential for adaptation in the residual bowel can undergo iLTx, but it is a treatment option to be exercised with extreme caution. These children need close follow-up with an experienced multidisciplinary team to monitor nutritional outcomes and may need consideration for transplant or nontransplant surgery in the long term.

Abstract
BACKGROUND Adalimumab is efficacious therapy for adults with Crohn's disease (CD). AIM To summarise the United Kingdom and Republic of Ireland paediatric adalimumab experience. METHODS British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) members with Inflammatory Bowel Disease (IBD) patients <18 years old commencing adalimumab with at least 4 weeks follow-up. Patient demographics and details of treatment were then collected. Response and remission was assessed using the Paediatric Crohn's Disease Activity Index (PCDAI)/Physicians Global Assessment (PGA). RESULTS Seventy-two patients [70 CD, 1 ulcerative colitis (UC), 1 IBD unclassified (IBDU)] from 19 paediatric-centres received adalimumab at a median age of 14.8 (IQR 3.1, range 6.1-17.8) years; 66/70 CD (94%) had previously received infliximab. A dose of 80 mg then 40 mg was used for induction in 41(59%) and 40 mg fortnightly for maintenance in 61 (90%). Remission rates were 24%, 58% and 41% at 1, 6 and 12 months, respectively. Overall 43 (61%) went into remission at some point, with 24 (35%) requiring escalation of therapy. Remission rates were higher in those on concomitant immunosuppression cf. those not on immunosuppression [34/46 (74%) vs. 9/24 (37%), respectively, (χ(2) 8.8, P=0.003)]. There were 15 adverse events (21%) including four (6%) serious adverse events with two sepsis related deaths in patients who were also on immunosuppression and home parenteral nutrition (3% mortality rate). CONCLUSIONS Adalimumab is useful in treatment of refractory paediatric patients with a remission rate of 61%. This treatment benefit should be balanced against side effects, including in this study a 3% mortality rate.

Abstract
AIMS The aims of this study were to describe the prevalence and clinical features of diabetes in hereditary haemochromatosis (HH), with particular emphasis to how this has changed since the introduction of genetic testing in 1996. SUBJECTS AND METHODS Two hundred and thirty-seven patients were diagnosed with HH (based on elevated iron indices and liver biopsy or genetic testing) by a single physician, and all biochemical and clinical data recorded from diagnosis to the end of the study. RESULTS The prevalence of diabetes (21.9%) was lower than most previously published studies. There was a significantly greater prevalence of diabetes and cirrhosis in those diagnosed before the introduction of genetic testing, p<0.001. The type of genetic mutation for HH, degree of ferritin elevation at diagnosis, or the presence of cirrhosis was not predictive for the development of diabetes. Iron depletion did not result in an improvement in glycaemic control or reduction in insulin requirements in the majority of patients. CONCLUSIONS This is one of the largest published series of diabetes in HH. Because the occurrence of diabetes in patients with HH reduces life expectancy, our finding of a lower prevalence of diabetes is expected to translate into a greater survival rate in these patients.

Abstract
BACKGROUND Active Crohn's disease can be treated using liquid diet therapy (LDT), but non-adherence may limit success, necessitating corticosteroid therapy. Whole-protein polymeric formula (PF) seems to be much more palatable than amino acid-based elemental formula (EF) and thus may significantly improve adherence to LDT. AIM To compare adherence to LDT using PF versus EF. METHODS Success in completing a 6-week course of LDT, need for nasogastric tube administration of formula and use of LDT for relapses were compared between children presenting with active disease and treated with EF (n = 53) and children given PF (n = 45). RESULTS Remission rates were similar (EF 64%, 95% CI 51 to 77 vs PF 51%, 95% CI 37 to 66; p>0.15). 72% (95% CI 60 to 84) given EF completed the initial course of LDT compared with 58% (95% CI 44 to 72) given PF (p = 0.15). Of those failing to complete the initial course, 13% on EF and 16% on PF gave up by choice (non-adherence), the remainder stopping due to treatment failure. Nasogastric administration was more frequent with EF (55%, 95% CI 42 to 68) compared to PF (31%, 95% CI 17 to 45) (p = 0.02). Among those treated successfully at first presentation, LDT was used for 28% of relapses in the EF group (95% CI 12 to 44) and 39% in the PF group (95% CI 19 to 59) (p>0.2) over the next year. CONCLUSION PF did not effect adherence to LDT but was associated with significantly reduced need for nasogastric tube administration of formula.

Abstract
We report a case of megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS), occurring in association with mydriasis, in a female infant born to consanguineous Asian parents. This association has not previously been reported and is of interest because mydriasis has been found in a murine MMIHS model produced by knockout of the genes coding for the alpha3 subunit or the beta2 and beta4 subunits of the neuronal nicotinic acetylcholine receptor. This may provide an important clue to the genetic basis of MMIHS in humans.

Abstract
BACKGROUND Little data exist on immunosuppressive drug absorption in children with short bowel syndrome and intestinal failure associated liver disease (SBS-IFALD). AIM To evaluate the absorption of immunosuppressive medications in children with SBS-IFALD undergoing isolated liver transplantation (iLTx). METHODS A retrospective review was performed in children with SBS-IFALD undergoing LTx and comparison made with weight, age-matched children undergoing iLTX (extra-hepatic biliary atresia (EHBA) and normal intestinal length and function). RESULTS Seven children with SBS-IFALD undergoing iLTx (median residual bowel length, 60 cm, range 40-80) were compared with 15 children undergoing LTx for EHBA. SBS-IFALD children had significantly lower trough tacrolimus levels at three months (5.8 vs. 7.9 ng/mL, p<0.05) and six months (5.0 vs. 8.0 ng/mL, p<0.05), but equivalent levels at 12 months after iLTx. The median calculated dose-normalized concentrations indicated that systemic availability of tacrolimus was comparable in two groups at 3, 6, 12 months (33.1 vs. 23.3; 42.4 vs. 36; 51 vs. 52.9) despite the differences in enteral function. The incidence of acute rejection was 1/7 (SBS-IFALD) and 10/15 (EHBA) group (p = 0.06). CONCLUSION Children with SBS-IFALD demonstrated adequate absorption of oral tacrolimus without significant acute rejection rate after iLTx suggesting that modification of immunosuppression is not necessary.

Abstract
BACKGROUND AND AIMS Total enteral nutrition (TEN) with a liquid formula can suppress gut inflammation and induce remission in active Crohn's disease. The mechanism is obscure. Studies have suggested that long term nutritional supplementation with a liquid formula (partial enteral nutrition (PEN)) may also suppress inflammation and prevent relapse. The aim of this study was to compare PEN with conventional TEN in active Crohn's disease. PATIENTS AND METHODS Fifty children with a paediatric Crohn's disease activity index (PCDAI)>20 were randomly assigned to receive 50% (PEN) or 100% (TEN) of their energy requirement as elemental formula for six weeks. The PEN group was encouraged to eat an unrestricted diet while those receiving TEN were not allowed to eat. The primary outcome was achievement of remission (PCDAI<10). Secondary analyses of changes in erythrocyte sedimentation rate (ESR), C reactive protein, albumin, and platelets were performed to look for evidence of anti-inflammatory effects. RESULTS Remission rate with PEN was lower than with TEN (15% v 42%; p=0.035). Although PCDAI fell in both groups (p=0.001 for both), the reduction was greater with TEN (p=0.005). Moreover, the fall in PCDAI with PEN was due to symptomatic and nutritional benefits. With both treatments there were significant improvements in relation to abdominal pain, "sense of wellbeing", and nutritional status. However, only TEN led to a reduction in diarrhoea (p=0.02), an increase in haemoglobin and albumin, and a fall in platelets and ESR. CONCLUSIONS TEN suppresses inflammation in active Crohn's disease but PEN does not. This suggests that long term nutritional supplementation, although beneficial to some patients, is unlikely to suppress inflammation and so prevent disease relapse.

Abstract
AIMS To determine the reliability of a panel of blood tests in screening for ulcerative colitis and Crohn's disease. METHODS The subjects were 153 children referred to a paediatric gastroenterology department with possible inflammatory bowel disease (IBD). Of these, 103 were found to have IBD (Crohn's disease 60, ulcerative colitis 37, indeterminate colitis 6). The 50 without IBD formed the controls. Blood tests evaluated included haemoglobin, platelet count, ESR, CRP, and albumin. Receiver operating characteristic curves were used where possible to determine optimal threshold values. Binary logistic regression analysis was used to investigate the five screening tests in combination, and a stepwise method was used to find the best test combination. RESULTS The optimal screening strategy used a combination of haemoglobin and platelet count and "1 of 2 abnormal" as the criterion for positivity. This was associated with a sensitivity of 90.8% (95% CI 83.3 to 95.7%), a specificity of 80.0% (95% CI 65.7 to 89.8%), and positive and negative predictive values of 94.4% and 75.9% respectively. CONCLUSIONS Haemoglobin and platelet count provide a useful screening test combination for patients with suspected IBD. These tests are not completely reliable however. If clinical suspicion is high further investigations are required.

Abstract
BACKGROUND In hereditary haemochromatosis (HH), the thyroid gland is the site of substantial iron deposition. However, there have been relatively few reported cases of thyroid dysfunction in HH. AIM To evaluate the prevalence of thyroid disorders in a large group of patients with HH. METHODS A variety of endocrine investigations were undertaken including thyroid function tests and thyroid antibody studies. RESULTS A total of 154 consecutive patients (123 male, 31 female) were studied. One case of primary hypothyroidism was identified, giving a prevalence of 0.6%. Subclinical hypothyroidism was identified in two females, giving a prevalence of 1.3%. Iatrogenic hypothyroidism was identified in two other cases. No case of hyperthyroidism was identified. CONCLUSION Thyroid dysfunction is an uncommon occurrence in patients with HH.

Abstract
UNLABELLED Confirmation of the diagnosis of coeliac disease requires unequivocal evidence of recovery on a gluten-free diet. The lactose H2 breath test is a non-invasive technique for detecting lactose malabsorption, and this may occur in untreated coeliac disease. The utility of this test was investigated in objectively confirming a response to gluten exclusion. The study included 44 children from 0.9 to 14.75 y of age (median 3.2) with coeliac disease. Five children were asymptomatic, being identified through coeliac antibody screening. Breath tests were performed prior to dietary treatment. If positive, they were repeated at 4-wk intervals following gluten exclusion. Overall, 21/44 (48%) children had positive breath tests at presentation. In 18/21 children on a gluten-free diet, this became negative after 4 wk (86%) and in all the children by 8 wk. In two children with positive tests at 4 wk, problems with dietary adherence were identified. A positive test before treatment was not associated with significant differences in individual symptoms, height, weight and body mass index standard deviation scores, serum haemoglobin or albumin. However, no positive results were found in the asymptomatic patients (p = 0.05). Lactose malabsorption was associated with earlier age of presentation (p = 0.008). CONCLUSION The lactose H2 breath test objectively confirms a response to gluten exclusion. In selected cases it can help confirm a diagnosis of coeliac disease. However, the test tends to be less informative in asymptomatic patients, and in older children.

Abstract
OBJECTIVE To investigate the use of (99m)Tc-HMPAO (hexamethyl propylene amine oxime) leucocyte scintigraphy as a non-invasive screening test for inflammatory bowel disease. PATIENTS 10 children with suspected Crohn's disease, in whom routine investigation using barium contrast radiology, upper gastrointestinal endoscopy, colonoscopy, and mucosal biopsies had identified severe gastroduodenal and/or jejunal involvement. DESIGN (99m)Tc-HMPAO leucocyte scintigraphic studies performed in each of these cases were assessed by a radiologist who was blinded to the disease distribution. RESULTS In nine cases there was no scintigraphic evidence of inflammation in the proximal gastrointestinal tract. The 10th child had both gastroduodenal and jejunal involvement, but scintigraphy only revealed faint jejunal positivity. CONCLUSIONS (99m)Tc-HMPAO leucocyte scintigraphy should not be depended upon as a screening test for Crohn's disease. False negative results are likely in cases with Crohn's disease confined to the proximal gastrointestinal tract.

Abstract
UNLABELLED In the 1970s several reports highlighted the long delay in diagnosis often experienced by children with Crohn's disease. In recent years this disorder has attracted much publicity, and many believe that the incidence has increased substantially. The aim of this investigation was to determine whether heightened awareness had shortened the interval to diagnosis, improved clinical management and reduced morbidity. A retrospective study was therefore carried out on 112 children with inflammatory bowel disease (64 Crohn's disease, 41 ulcerative colitis, 7 indeterminate colitis) referred to a paediatric gastroenterology department in the UK between 1994 and 1998. In Crohn's disease the median interval to diagnosis was 47 wk (maximum 7 y). In those without diarrhoea this was longer (66 vs 28 wk; p = 0.005). In ulcerative colitis the median interval was 20 wk (maximum 3 y). Even in severe colitis the median interval was 5.5 wk (range 3-9 wk) and 4 required urgent colectomy soon after referral. Many with unrecognized Crohn's disease had undergone inappropriate treatments, such as growth hormone or psychiatric therapy. Nineteen (17%) had undergone endoscopic investigations in adult units prior to referral. Malnutrition was equally common in Crohn's disease and ulcerative colitis (11%). Short stature was present in 19% with Crohn's disease, and 5% with ulcerative colitis, and was severe in 8% with Crohn's disease. There was a significant correlation between symptom duration and the degree of growth impairment present (r(s) = -0.4; p = 0.004). CONCLUSION This study suggests that late diagnosis and inappropriate investigation and management are still significant problems.

Abstract
BACKGROUND Upper gastrointestinal endoscopic biopsies often show histologic abnormalities in Crohn disease. Consequently, it has been proposed that routine endoscopy could help to distinguish Crohn disease from ulcerative colitis. Surprisingly, however, recent case reports and an uncontrolled study suggested that similar abnormalities may occur in ulcerative colitis. Therefore, a blinded, controlled study was performed. METHODS Esophageal, gastric antral, and duodenal biopsies from children with Crohn disease (n = 28) and ulcerative colitis (n = 14) were compared with those from controls undergoing endoscopy for suspected reflux esophagitis (n = 22). Two pathologists, unaware of patient identity and diagnosis, agreed on a consensus report. Severity of inflammation was scored semiquantitatively. Helicobacter pylori colonization was an exclusion criterion. RESULTS Inflammation was reported as follows: esophagitis: controls 91%; Crohn disease: 72%; ulcerative colitis: 50%; gastritis: controls: 27%; Crohn disease: 92% (P < 0.001); ulcerative colitis: 69%; duodenitis: controls: 9%; Crohn disease: 33%; ulcerative colitis: 23%. In Crohn disease, granulomas were noted in 40% of patients (P = 0.001). Duodenal cryptitis was noted in 26% of patients with Crohn disease but not ulcerative colitis. In one patient with ulcerative colitis, neutrophilic infiltration of gastric glands was seen. Abnormalities seen in Crohn disease and ulcerative colitis included gastroduodenal ulceration (Crohn disease, 7%; ulcerative colitis, 8%), villus atrophy (Crohn disease, 11%; ulcerative colitis, 15%), and increased intraepithelial lymphocytes (Crohn disease, 15%; ulcerative colitis, 31% [P < 0.05]). None of these abnormalities was noted in the controls. CONCLUSION Although the presence of granulomas can support a diagnosis of Crohn disease, severe inflammation and other abnormalities occur in the proximal gastrointestinal tract in Crohn disease and ulcerative colitis.

Abstract
Controversy persists regarding optimal management of perilunate injuries. Traditionally, closed treatment, with or without percutaneous pin fixation, was advocated for these highly unstable carpal disruptions, but the inconsistent and often disappointing outcome of closed reduction, coupled with the recognition that functional recovery closely parallels the accuracy of restoring carpal alignment, have led to increasing enthusiasm for open treatment. The favorable outcome reported in this article supports both the contention that the acute perilunate injury affords the opportune time for operative preservation of carpal stability and the efficacy of the combined dorsal and volar approaches as the optimal means of surgical repair. This clinical experience also corroborates experimental evidence that perilunate injuries are apt to cause a predictable spectrum of osseous and soft tissue lesions--lesions usually suitable for early, precise repair. For the skilled athlete, prompt recognition and precision treatment of all components of injury are the critical factors to attain a functional outcome commensurate with a successful return to competition.

Abstract
This paper reviews areas of interest in gut mucosal growth factor physiology. Several epidermal growth factor (EGF)-like peptides (EGF, transforming growth factor [TGF]-alpha, heparin-binding EGF-like peptide, amphiregulin, and betacellulin) have been identified in the gut, EGF is produced by the salivary glands and is present in milk. It may act on the mucosa from the lumen as a surveillance peptide promoting mucosal repair. A stem-cell-derived "ulcer-associated cell lineage" develops adjacent to ulcers and produces EGF, which may play a role in ulcer healing. TGF-alpha is expressed by villus enterocytes and may have an important role in mucosal healing. The Trefoil peptides (pS2, spasmolytic polypeptide, intestinal trefoil factor) are protease resistant molecules secreted by mucin cells throughout the gut, with a role in mucosal healing. The TGF-beta family inhibit cell proliferation, and promote cell differentiation. TGF-beta has a gradient of expression along the crypt villus axis, with maximum production at the villus tip. It is suspected that it may prevent cell proliferation and support differentiation of villus enterocytes. Hepatocyte growth factor is a multifunctional growth factor expressed in many tissues, including the gastrointestinal tract. It has a role in organogenesis. Intestinal adaptation is highly dependent on enteral nutrition, and it is likely that growth factors are involved in adaptation. Little is known, however, about interactions between nutrients and growth factors. Milk contains a range of potentially important growth factors. Their biological significance is uncertain, and this is an area of active research.

Abstract
INTRODUCTION Advanced patient stabilization skills provided by air medical providers were hypothesized to result in streamlined emergency department (ED) stabilization of patients with head injuries requiring urgent cranial computed tomography (CCT). The goal of this study was to compare initial ED stabilization times between air- and ground-transported patients requiring urgent CCT and emergency neurosurgical hematoma evacuation. SETTING Academic Level trauma center (annual ED census 60,000) receiving patients from ground EMS and a nurse/paramedic air medical transport team. METHODS This retrospective study identified, from a database of 15 months of ED visits, consecutive group of adults who had CCT performed within 60 minutes of ED arrival and underwent emergent craniotomy for intracranial hematoma. Demographics, hemodynamic status, patient acuity, and time intervals between ED and CCT suite arrivals were compared between air and ground patients using chi-square, Fisher's exact, and t-tests (p = 0.05). RESULTS Eleven air- and 39 ground-transported patients were eligible. All patient acuity data were similar between groups. Air patients were more likely to be intubated (100% versus 71.8%, p = .04) and had shorter mean ED stabilization times (29 versus 40 minutes, p = .02) than the ground. CONCLUSION This study suggests that advanced patient stabilization offered by air medical transport may result in reduced ED stabilization time for patients requiring urgent craniotomy.

Abstract
The rectal "inflammatory cloacogenic polyp" is a recognized pathologic entity in adulthood. We report three cases in children aged between 8 and 12 years. This disorder should be included in the differential diagnosis in patients with hematochezia and tenesmus. These polyps are usually located at the anorectal junction and so may be overlooked at colonoscopy unless an endoscopic retroflexion maneuver is performed.

Abstract
After liver transplantation, a relatively low intensity immunosuppressive regimen is employed in our unit: after initial triple therapy (prednisolone, azathioprine, cyclosporin), prednisolone is discontinued at three months and azathioprine at one year. A retrospective study was therefore performed to determine the incidence of rejection, and to identify risk factors for rejection in our patient population. Over a 10 year period, 135 transplants were performed on 109 children. Thirty four (25%) were on infants less than 1 year old. Incidences of acute rejection and irreversible chronic rejection were calculated for grafts surviving more than one and four weeks respectively. Acute rejection occurred in 51 of 101 allografts (50%), and irreversible chronic rejection in 11 of 91 allografts (12%). The immunosuppression strategy was not associated with an increased incidence of rejection. Acute rejection occurred in only eight of 28 allografts (29%) in those transplanted during their first year, compared with 43 of 73 (59%) in older children. Logistic and Cox regression analysis supported age at transplantation as a significant risk factor for acute rejection. Irreversible chronic rejection did not occur in any of 24 grafts in patients transplanted before one year, compared with 11 of 67 (16%) in older recipients. This suggests possible enhanced allograft tolerance with transplantation during the first year of life. This unexpected and potentially important finding now requires confirmation in other large patient series, with blind interpretation of post-transplant liver biopsies.

Abstract
Radiopalmar opening wedge osteotomy was used in 11 female patients (12 wrists) with Madelung's deformity who ranged in age from 9 to 31 years. Five patients met the radiographic criteria for generalized dyschondrosteosis. Clinically, there was dissatisfaction with the appearance of the wrist. The principal motion deficits were in radiocarpal extension and forearm pronosupination associated with varying degrees of discomfort with sustained activity. All had a decreased radioulnar angle, lunate subluxation shown radiographically, and various degrees of dorsal subluxation of the ulnar head. Indications for surgery were pain, limited motion, cosmetic appearance, and progressive deformity in two immature patients. Biplanar corrective opening wedge osteotomy of the radius was performed with iliac crest graft. Three patients had an added ulnar recession. Fixation was with a plate or Kirschner wire. Supplementary distracting external fixation was used in six cases. The follow-up period averaged 48 months. Pain relief in all patients was satisfactory. Range of motion and grip strength were not influenced. The radioulnar angle improved by 11 degrees, but lunate subluxation was minimally changed. Length of the forearm and bowed appearance of the forearm were improved. Reduction of the radioulnar joints was improved but remained incongruous.

Abstract
OBJECTIVE To describe four infants with protracted diarrhea caused by glucose polymer intolerance resulting from congenital sucrase-isomaltase deficiency. METHODS The diagnosis of congenital sucrase-isomaltase deficiency was established by mucosal disaccharidase assay. In each case the clinical response to discontinuation of glucose polymer was documented. RESULTS The median age at the onset of symptoms was 3 weeks (range, 2 to 16 weeks). In three infants the formula had been prescribed for presumed postgastroenteritis diarrhea, and in a fourth it was begun after resection of a short-segment congenital ileal atresia. In each infant watery diarrhea occurred and persisted for many months, and it was assumed that the original gastrointestinal disorder was responsible. In two cases, parenteral nutrition was administered for persistent failure to thrive. Ultimately, investigation revealed the underlying congenital sucrase-isomaltase deficiency, and elimination of glucose polymer from the diet led to immediate recovery in each case. CONCLUSION Congenital sucrase-isomaltase deficiency should be considered a possible cause of protracted diarrhea in infants receiving glucose polymer-based feedings.

Abstract
Twenty two children were evaluated for small bowel transplantation between 1989 and 1994. Eight were unfit for transplantation and died within three months; a raised plasma bilirubin concentration (> 200 mumol/l) predicted death from liver failure within six months (p = 0.0001). The 11 children who were not managed by a multidisciplinary nutritional care team were less well nourished at referral, had more complications with intravenous feeding catheters, and greater early mortality while awaiting transplantation (p < 0.05). It is recommended that children with chronic intestinal failure be referred for assessment early, before liver dysfunction is established.

Abstract
Between 1983 and 1992, 112 children underwent liver transplantation. Of 138 grafts, 60 (43.4%) were whole livers, 77 (55.6%) were reduced livers, and 1 (0.7%) was a split liver. Biliary complications (BC) were defined as any abnormality, even minor, related to the biliary tract. Results were analysed with a minimum follow-up of 9 months. Some 36 grafts (26.1%) in 34 patients (30.4%) presented with BC: bile leaks (17 grafts), biliary obstructions or dilatations (16 grafts), and other complications (3 grafts). Management was mainly surgical with biliary reconstruction via a Roux-en-Y loop. Interventional radiology had an increasing role in recent years. BC were associated with a mortality of 1.8% (2/112), a graft loss rate of 4.3% (6/138), and significant morbidity. Among the various factors whose association with BC was studied, the date of transplantation, the use of reduced grafts and the use of gallbladder conduits appeared to be the main determining factors for BC. From multivariate analysis the use of reduced grafts emerged as the most important factor in reducing BC. We therefore conclude that BC are associated with significant morbidity, but general improvements in both surgical and medical management seem to account for better results in recent years.

Abstract
The performance of the ONLINE Assay for Amphetamines on the Hitachi 737 was compared to the Syva Emit d.a.u. Assay and GC/MS. Randomly screened (n = 2964) patient urine samples were assayed using ONLINE and Emit d.a.u. assays concurrently, using d-amphetamine, 1000 ng/mL and d-methamphetamine, 1000 ng/mL as the screening cutoff for ONLINE and Emit d.a.u. assays, respectively. All presumptive positives were confirmed by GC/MS. The specificity was 99% (2937/2964) for ONLINE and 97% (2873/2964) for Emit. Agreement with GC/MS was 80% (110/137) for ONLINE and 55% (110/201) for Emit.

Abstract
Intestinal dysmotility may be an important factor contributing to various gastrointestinal complications associated with cystic fibrosis. Motilin, enteroglucagon, neurotensin, and peptide YY may each play a role as endocrine hormones influencing gastrointestinal motor activity. Fasting children with cystic fibrosis (N = 8) and controls (N = 18) received a liquid nutrient test meal (fat 4 g/100 ml, protein 4 g/100 ml, carbohydrate 20 g/100 ml, 125 kcal/100 ml; 200 ml/m2) containing lactulose (5 g/100 ml), and the plasma concentrations of these peptides were studied. Mouth-to-cecum transit time was simultaneously studied using the breath H2 technique. Fasting levels of peptide YY and the postprandial response of all four peptides were significantly increased in those with cystic fibrosis. In repeat studies on those with cystic fibrosis after a period of altered pancreatic enzyme supplementation, no significant changes in peptide concentrations were observed. A rise in breath H2 permitting estimation of mouth-to-cecum transit time was noted in 17 control subjects (70-220 min, median 140). In contrast, a rise occurred in only two with cystic fibrosis after low-dose enzyme (70 and 180 min), and four after high-dose enzyme replacement (120-230 min, median 155). Altered gut hormone secretion may play a role in the pathophysiology of intestinal dysmotility in patients with cystic fibrosis.
