Abstract
Twenty five per cent of inflammatory bowel disease presents in childhood. Growth and nutrition are key issues in the management with the aim of treatment being to induce and then maintain disease remission with minimal side effects. Only 25% of Crohn's disease presents with the classic triad of abdominal pain, weight loss, and diarrhoea. Most children with ulcerative colitis have blood in the stool at presentation. Inflammatory markers are usually although not invariably raised at presentation (particularly in Crohn's disease). Full investigation includes upper gastrointestinal endoscopy and ileocolonoscopy. Treatment requires multidisciplinary input as part of a clinical network led by a paediatrician with special expertise in the management of the condition.

Abstract
BACKGROUND Enteral nutrition (EN) is widely used and is effective in the treatment of children with Crohn's disease given as an exclusive feed for 6-8 weeks. Current dietetic practice during EN is to recommend an energy intake based on estimated average requirement (EAR) for energy for age. AIMS To examine factors affecting energy intake and weight gain during EN in relation to disease site and nutritional status. METHODS A retrospective cohort study examining energy intake and weight gain during the exclusive EN feeding period in 40 patients newly diagnosed with Crohn's in relation to EAR, nutritional status, disease site. RESULTS All patients improved clinically and gained weight during EN with improvement in the CRP as a marker of the systemic inflammatory response. Energy intake was higher than EAR in 82% (33/40 patients), with the median 117.5% of EAR. Weight gain correlated with body mass index standard deviation score (P = 0.001) at start of treatment, but not energy intake or CRP. CONCLUSION Estimated average requirement underestimates energy intakes in most children with newly diagnosed Crohn's disease. During EN, an energy intake in the range of 100-149% (median 117.5%) EAR for energy for age may be required. Energy balance studies in children with active disease are required.

Abstract
INTRODUCTION The aim of the study was to assess if the estimated average requirements for energy for normal children (EAR) and the Schofield equation could reliably predict energy requirements in children with inactive Crohn's disease (CD). METHODS Twenty-three children with inactive CD were studied, median age 14.3 years (range 7.8-16.9). Resting energy expenditure (REE) was measured by indirect calorimetry and compared with that predicted using the Schofield equation (BMR). Total energy expenditure (TEE) was measured using REE and a 3-day activity diary and compared with EAR. RESULTS REE ranged from 79% to 136% of BMR. Mean REE was not significantly greater than mean BMR (P=0.25 2-tailed t-test). TEE ranged from 72% to 163% of estimated average requirements for energy for children of that weight (EARw). EARw tended to underestimate TEE in large children and overestimate TEE in small children (Bland-Altman plot R=0.5, P=0.002). EARw was a poor predictor of TEE (R=0.35, P=0.1). EAR underestimated energy requirements by >500 kcal/day in 40% of the children. CONCLUSIONS The Schofield equation and EAR are unreliable methods of predicting total energy requirements in children with inactive CD with a significant potential to underestimate energy needs. When energy requirements were greater than EAR it was due to physical activity and body habitus rather than raised REE.

Abstract
AIM Bowel wall thickening on transabdominal ultrasound scanning (USS) correlates well with Crohn's disease (CD) activity. However, the role of USS in the assessment of CD has not been fully defined. This study compared USS and barium follow-through (BaFT) in the assessment of CD. METHODS A retrospective case series was undertaken of 24 children with CD who underwent USS and BaFT during the same period of clinical disease activity. RESULTS For terminal ileum abnormality, all 13 cases with abnormal USS had abnormality on BaFT. USS did not detect five cases with affected terminal ileum and two cases with isolated proximal small-bowel CD. CONCLUSION BaFT is a more sensitive indicator of small-bowel CD than USS. USS has good positive predictive value of distal small-bowel CD, but BaFT should be performed in the presence of a normal USS where there is strong clinical evidence of CD.

Abstract
BACKGROUND Active paediatric Crohn's disease is associated with nutritional deficiencies and altered nutrient intake. The availability of essential fatty acids (linoleic and alpha-linolenic acids) or their derivatives (arachidonic and eicosapentaenoic acids) may alter in plasma and cell membrane phospholipid in protein-energy malnutrition in children and in Crohn's disease in adults. AIM To investigate the relationship of fatty acid phospholipid profiles with disease activity and nutritional status in paediatric Crohn's disease. METHODS The fatty acid (proportionate) composition of plasma and erythrocyte phosphatidylcholine was determined in 30 patients (10.3-17.0 years) stratified into active and quiescent Crohn's disease (paediatric Crohn's disease activity index) and high and low body mass (body mass index centile). RESULTS In plasma phosphatidylcholine, active disease activity was associated with a lower level of alpha-linolenic acid compared with that in quiescent disease (P < 0.05). A body mass index below the 50th centile was associated with active Crohn's disease, low linoleic and alpha-linolenic acids and high arachidonic acid (P < 0.05) in plasma phosphatidylcholine, and low alpha-linolenic acid in erythrocyte phosphatidylcholine. These findings could not be explained through differences in habitual dietary fat intake. CONCLUSION In paediatric Crohn's disease, a low body mass index centile and high disease activity are associated with altered profiles of essential fatty acids and their derivatives, which may reflect altered metabolic demand.

Abstract
UNLABELLED Eutectic mixture of local anaesthetics (EMLA) cream is used routinely as a local anaesthetic prior to venepuncture in children. Despite this, however, a significant proportion of children will still be distressed. Cognitive-behavioural interventions, such as distraction by breathing and blowing exercises, have been used and found to be helpful as alternative coping strategies. There is, however, a paucity of data regarding effectiveness. We have evaluated the efficacy of distraction therapy as a coping strategy before and during venepuncture, and in these children evaluated the need for EMLA using a prospective, randomized, double-blind, placebo-controlled clinical trial. Twenty-eight children attending for venepuncture were recruited, median age 6 y (range 4-8 y), and randomly allocated to receive either EMLA or a placebo cream. All were given distraction therapy prior to and during the procedure by a play specialist. Venepuncture was carried out by one investigator. A modified paediatric pain assessment chart was used for objective pain score at the end of the procedure. After one exclusion, the treatment group (17 children) and the placebo group (10 children) were similar: median age of 6 and 7 y (range 4-8), median baseline and post-procedure heart rate and oxygen saturation. The median (interquartile range) for total pain score in the treatment group was 1 (0 to 4.5) and in the control group 1 (0 to 2.3). There was no significant difference in pain score between the two groups (Mann-Whitney test, p = 0.7). The 95% confidence interval for the difference in pain score was -1.0 to +3.0. CONCLUSIONS The low pain score in both groups suggests the effectiveness of distraction therapy, although factors such as skill of the operator and previous experience of the patient group are of relevance. There was no significant difference in the pain score between the EMLA and placebo groups, suggesting that in this age group if carefully selected children receive distraction during venepuncture EMLA may not be necessary.

Abstract
Crohn's disease in childhood is a chronic relapsing condition with a high morbidity. Growth failure is common. The aim of therapy is to induce and then maintain disease remission and thereby promote well-being and normal growth and development. Enteral nutrition (either polymeric or elemental) is effective and used as initial therapy. This is employed as sole therapy over a 6- to 8-week period followed by a period of controlled food reintroduction. The relapse rate is high and further courses of enteral nutrition or alternative therapies are frequently required. Corticosteroids are also effective as initial therapy and are required in difficult cases but there are problems with their long term use, particularly their adverse effects on growth. Many patients develop either corticosteroid-dependent or corticosteroid-resistant disease. In this instance, additional immunosuppression, such as azathioprine, can be used. Surgery is required for those patients with disease resistant to medical therapy and this will result in remission; however, the relapse rate with surgery is high. There are many areas for future research. Very little is known about why enteral nutrition works, how long it should be given or its role as maintenance therapy. Newer immunosuppressive strategies based on cytokine modulation may be helpful in children once more experience is gained from their use in adults.

Abstract
BACKGROUND Although enteral nutrition is a recognized form of treatment for intestinal Crohn's disease, there are persisting problems with feed palatability and only limited data as to its mode of action. AIM To assess the effects of a specific oral polymeric diet (CT3211; Nestle, Vevey, Switzerland), which is rich in transforming growth factor beta2, on the mucosal inflammatory process. METHODS Twenty-nine consecutive children with active intestinal Crohn's disease were treated with CT3211 as the sole source of nutrition for 8 weeks. Patients were assessed clinically, and endoscopically, whilst cytokine mRNA was measured in mucosal biopsies before and after treatment by quantitative reverse transcriptase polymerase chain reaction. RESULTS After 8 weeks 79% of children were in complete clinical remission. Macroscopic and histological healing in the terminal ileum and colon was associated with a decline in ileal and colonic interleukin-1beta mRNA (pre-treatment to post-treatment ratio 0.008 and 0.06: P < 0.001, P = 0.006). In the ileum there was also a fall in interferon gamma mRNA (ratio 0.15, P < 0.001) with a rise in transforming growth factor beta1 mRNA (ratio 10, P = 0.04), whilst in the colon interleukin-8 mRNA fell with treatment (ratio 0.06, P < 0.05). CONCLUSIONS The clinical response to oral polymeric diet CT3211 is associated with mucosal healing and a down regulation of mucosal pro-inflammatory cytokine mRNA in both the terminal ileum and colon. In the ileum there was also an increase in transforming growth factor beta1 mRNA.

Abstract
OBJECTIVES To assess the clinical features, investigations and outcome of 69 children (40 males, 29 females) with gastro-oesophageal reflux (GOER) referred to a tertiary referral centre in paediatric gastroenterology. METHODS A study of all patients with significant GOER seen at the Paediatric Gastroenterology Unit, Queen Elizabeth Hospital for Children, Hackney Road, London, between December 1994 and August 1995. RESULTS The median age at referral was 16 months. Presenting symptoms were recurrent vomiting (72%), epigastric and abdominal pain (36%), feeding difficulties (29%), failure to thrive (28%) and irritability (19%). Continuous 24-h lower oesophageal pH studies performed in 57 children showed 20 (35%) had a reflux index of between 10% to 20%, 14 (25%) had a index > 20%, and six (11%) had a postprandial reflux index > 10%. Reflux was shown in 38 (62%) of 62 children who underwent barium studies. None had significant anatomical abnormalities, but in the 22 children who had a negative barium studies, six had severe reflux (reflux index > 20%). Upper gastrointestinal endoscopy performed in 47 children showed reflux oesophagitis in 29 (62%), oesophageal ulceration in three, and Barrett's oesophagus in one. All of the children were treated with standard medical therapy. Sixty-six per cent were able to discontinue medication within 12 months and remained well. Four children (6%) required Nissen's fundoplication for failure to respond to medical therapy. CONCLUSIONS Most infants with GOER have an uncomplicated course. False negative results were noted in both pH monitoring and barium meal. Up to 80% of children, with therapy, will improve within 12 months.

Abstract
Abnormal linear growth is frequent in children and adolescents with Crohn's disease. The typical pattern is of growth retardation associated with delayed skeletal maturation. Puberty is also frequently delayed. Over 50% of patients may have a subnormal height velocity, and approximately 25% will have short stature. The endocrine status is characterized by normal growth hormone secretion and a slightly subnormal serum level of insulin-like growth factor I, which is related to nutritional status. Principal therapeutic options are intestinal resection for localized disease, and enteral nutrition--using a polymeric diet--for more widespread disease, particularly involving the small intestine. Growth responses to both modalities are often excellent and produce considerable psychological benefit. Optimum therapy is achieved by close collaboration between gastroenterologists and endocrinologists, and by the use of auxological methods to document pre- and post-therapeutic management.

Abstract
OBJECTIVE Abnormal linear growth is common in childhood and adolescent Crohn's disease. We have studied the concentrations of the inflammatory marker CRP and of serum IGF-I and IGFBP-3 in patients with active Crohn's disease and have assessed the changes in these parameters during therapeutic intervention with enteral nutrition or intestinal resection. DESIGN Children and adolescents attending the inflammatory bowel disease clinic at our hospital underwent treatment either with enteral nutrition (Study A) or intestinal resection (Study B). These are two separate studies and the results cannot be compared. Serum concentrations of CRP, IGF-I and IGFBP-3 were determined at 0, 2, 8 and 16 weeks after start of enteral nutrition and in addition to height velocity, at 0 and 6 months after intestinal resection. SUBJECTS Study A: 14 patients, 9 male, 5 female, median age 12.5 years (range 7.0-17.2), puberty stage 1 (n = 13), stage 3 (n = 1). All had active Crohn's disease. Study B: 9 patients, 7 male, 2 female, median age 13.5 years (range 7.8-16.5), puberty stage 1 (n = 5), stages 2-4 (n = 4). All had Crohn's disease resistant to medical therapy. METHODS Crohn's disease was confirmed radiologically, endoscopically and histologically. Disease activity was scored using the Lloyd Still index (LSI). Study A: nutritional support was with a polymeric, casein-based formula feed AL 110. Study B: surgical procedures were small bowel resection (n = 2), right hemicolectomy (n = 5), subtotal colectomy (n = 2). MEASUREMENTS Study A: weight SDS, CRP, IGF-1 and IGFBP-3 were measured at 0, 2, 8, 16 weeks after start of enteral feeding. Study B: height velocity, CRP, IGF-I and IGFBP-3 were measured 0, 6 months after intestinal resection. STATISTICAL ANALYSIS Medians and ranges were used. Significance of changes was calculated using the Wilcoxon rank test for the analysis of paired data. RESULTS Study A: median LSI before treatment was 39 and increased after 8 weeks of enteral nutrition to 60 (P < 0.05). Weight SDS increased at 8 and 16 weeks (P < 0.05) compared to pretreatment. CRP was elevated at 0 weeks, falling during treatment. Median (range) values (normal < 5 mg/l) at 0 at 2, 8, 16 weeks were 53 mg/l (15-150), 8 mg/l (5-25), 7 mg/l (5-83) and 14 mg/l (5-39), all P < 0.001 compared with pretreatment. Median IGF-I-values increased during treatment. Median (range) values at 0, 2, 8, 16 weeks (all P < 0.005) compared to pretreatment, median (range) values at 0, 2, 8, 16 weeks were 78 micrograms/l (50-204), 131 micrograms/l (73-251), 119 micrograms/l (77-291) and 133 micrograms/l (67-497), all P < 0.005 compared to pre-treatment. IGFBP-3 levels increased during treatment. Median (range) values at 0, 2, 8, 16 weeks were 2.4 mg/l (1.4-3.1), 2.9 mg/l (1.8-4.6), 3.0 mg/l, 3.2 mg/l (1.8-4.5), all P < 0.01 compared to pretreatment. Study B: height velocity increased during 6 months after surgery. Median (range) values; 3.3 cm/year (0-8.3) before surgery, 8.4 cm/year (2-12.6) 6 months post-surgery, P < 0.01. Median (range) CRP values fell from 45 mg/l (5-150) to 8 mg/l (5-31) and IGF-I-values increased from 163 micrograms/l (64-286) to 226 micrograms/l (71-391). These changes were not statistically significant. IGFBP-3 values did not change. CONCLUSION The IGF system, as shown by serum IGF-I and IGFBP-3, is responsive to therapeutic intervention in active Crohn's disease. It is likely that a combination of decreased inflammatory activity and improved nutrition contributes to these changes.

Abstract
Enteral diets, both elemental and, more recently, polymeric (whole protein), are used as primary therapy in Crohn's disease and can induce disease remission without the concomitant use of immunosuppressive drugs. Controlled trials comparing enteral nutrition with corticosteroid therapy have given mixed results but suggest, at least in children, that they are as effective as corticosteroids in inducing remission. There is no clear consensus as to which dietary therapy is best. Elemental diets do not seem to be superior to polymeric whole protein-based diets, although further work is necessary. The effect of enteral diets does not seem to be related to the site of intestinal inflammation. Enteral nutrition is particularly appropriate in children and adolescents with Crohn's disease, improving nutrition and promoting growth and pubertal development, and avoiding the systemic toxicity of corticosteroid therapy. Most centers will use it as a first line of treatment. Supplementary enteral nutrition after primary therapy and remission induction may be associated with the prolongation of remission and promotion of linear growth. Pathways by which enteral diets may affect mucosal inflammation are discussed. Enteral diets may inhibit intestinal immune responses by reducing the number of cytokine-producing cells. Enteral nutrition may also boost immunosuppressive pathways, which then endogenously suppress ongoing inflammation. Enteral diets may promote epithelial healing and reepithelialization of Crohn's ulcers and may also reduce the bacterial load in the small bowel.

Abstract
AIM To assess the safety and efficacy of EMLA cream (eutectic mixture of local anaesthetics) used to induce surface anaesthesia for venepuncture in healthy preterm infants. METHODS Nineteen infants, median gestational age 31 weeks (range 26-33 weeks) were assessed in a randomised, double blind, placebo controlled, cross-over trial. Changes in physiological variables (heart rate, blood pressure, oxygen saturation) and behavioural responses (neonatal facial coding system score, crying time) before and after venepuncture with EMLA cream were compared with those obtained with a placebo cream to assess efficacy. Toxicity was assessed by comparing methaemoglobin concentrations at 1 hour and 8 hours after application. RESULTS There was no significant difference in efficacy between EMLA and placebo creams in physiological and behavioural responses. There was no significant difference in methaemoglobin concentrations one hour after the cream had been applied. At eight hours, however, concentrations were significantly higher after EMLA than placebo (p = 0.016). There was no evidence of clinical toxicity. CONCLUSION This study does not support the routine use of EMLA for venepuncture in healthy preterm infants.

Abstract
In children with complicated inflammatory bowel disease, conventional ultrasound imaging may not define the extent of extraluminal disease and the involvement of other viscera. Three children with chronic inflammatory bowel disease are presented, where computed tomography was well tolerated and provided valuable information on extraluminal disease, involvement of other organs, and the state of the bowel wall and mesentery. In children in whom ultrasound examination is inconclusive or limited by gas or tenderness, computed tomography can provide important information that may determine clinical management.

Abstract
Twenty children with active ulcerative colitis were assessed before and after 8 weeks of medical therapy with 5-aminosalicylic acid (5-ASA) derivatives and corticosteroids. Local therapy was given for distal disease (seven cases); other disease was treated with oral prednisolone (1-2 mg/kg/day, maximum 40 mg). Eighteen of the children showed a clinical improvement on therapy, and complete remission of clinical disease activity by 8 weeks was seen in 17 (85%). C-reactive protein was elevated initially in 10 of 20 children and returned to normal posttreatment in all but one. Reassessment of the colon after treatment showed an improved endoscopic appearance in 15 and complete remission in eight (40%). Histological improvement was seen in 13, with full remission in only three (15%). In conclusion, remission of clinical disease activity by corticosteroid therapy in ulcerative colitis may not be accompanied by endoscopic remission and uncommonly by mucosal healing. This finding may be important prognostically because of the risk of dysplasia in long-standing persistent mucosal inflammation.

Abstract
A total of 50 children with Crohn's disease were examined by barium follow-through and colonoscopy with ileoscopy, to determine the value of small bowel radiology. Of these children, 40 (80%) had evidence of small bowel Crohn's disease on ileoscopy and/or barium follow-through. Twenty-two (44%) had disease confined to the terminal ileum. Radiology diagnosed disease proximal to the terminal ileum in 18 cases (36%), including 5 children in whom the terminal ileum was normal. Ileoscopy was not possible in nine patients (18%), six of whom had small bowel disease on barium follow-through. Colonic involvement, demonstrated in 34 (68%), was the sole site of disease in 6 (12%). Fifteen (30%) children had surgery, which in six (12%) was determined by the radiological findings of complicated small bowel disease. As the terminal ileum may be uninvolved in the presence of proximal ileal disease, normal ileoscopy does not exclude small bowel Crohn's disease. Small bowel radiology remains necessary to assess the full extent of Crohn's disease in children.

Abstract
BACKGROUND Corticosteroids are widely used to treat children with inflammatory bowel disease although the response is variable, side-effects are common, and many patients develop a partial or complete steroid resistance. The mechanism underlying these phenomena are unclear. Corticosteroids mediate some of their actions through lipocortin-1, and the induction of autoantibodies to lipocortin has been proposed as a possible mechanism by which steroid efficacy is suboptimal in vivo. PATIENTS AND METHODS We have measured serum lipocortin-1 antibody concentration by ELISA in 38 children with Crohn's disease, 12 with ulcerative colitis and in 15 controls. RESULTS IgG and IgA anti-lipocortin-1 antibody levels were higher in the Crohn's group than in the ulcerative colitis or control groups. Elevated concentrations did not relate to disease activity, history of steroid therapy or steroid-responsiveness. Lipocortin IgM antibody status was similar in all three groups. CONCLUSION It is therefore unlikely that serum antibodies to lipocortin-1 have a role in the development of steroid-resistance in children with inflammatory bowel disease.

Abstract
Simple routine blood tests (full blood count, platelet count, erythrocyte sedimentation rate, C reactive protein, and serum albumin) may select children with chronic gastrointestinal symptoms who require endoscopic assessment and are thus an important aid in the prediction of endoscopic status. When all of the results are normal then chronic inflammatory bowel disease is an unlikely diagnosis.
