Most of the children operated for esophageal atresia will survive the neonatal period. However, medium-term and late complications are frequent in this population. Gastroesophageal reflux disease is observed in 26 to 75% of the cases and can be responsible for peptic esophagitis, anastomotic stenosis, and Barrett esophagus, which is a risk factor for adenocarcinoma of the esophagus. Dysphagia is frequently observed, sometimes several years after the surgery, affecting up to 45% of children at the age of 5 years. Growth retardation is present in nearly one-third of children at the age of 5 years. Ear, nose, and throat and respiratory complications are also very frequent but tend to improve with time. Tracheomalacia is found in 75% of these children at birth, sometimes responsible for severe complications (malaise, bradycardia). Respiratory symptoms are dominated by chronic cough, wheezing, and infections reported in 29% of the children by the age of 5 years. Restrictive, obstructive syndromes and bronchial hyperactivity can be observed, but usually remain moderate. All these complications can influence the patient's quality of life, which is moderately impaired compared to healthy controls. The high frequency of late sequelae in esophageal atresia justifies regular and multidisciplinary follow-up through adulthood.

Physical activity accounts for 25-30 % of total daily energy expenditure. Total energy expenditure varies according to the physical activity, which can be voluntarily modulated. Assessment of physical activity is therefore an important factor in the promotion of health and in several childhood and adolescent pathological situations. Questionnaires are widely used for assessing physical activity patterns in youth because of their low cost and ease of use, but they systematically overestimate physical activity. Heart rate monitoring requires individual calibration in the laboratory and a number of factors other than physical activity can affect heart rate (i.e., stress, temperature, etc.). Pedometers are objective devices but give only information on the number of steps and do not assess physical activity patterns. Accelerometers seem the best compromise between feasibility and validity in the assessment of physical activity in children in free-living conditions because this is an objective and accurate method whose cost is low. The choice of the type of device depends on the objectives of the clinician or researcher.

Although initial prognosis of oesophageal atresia is nowadays excellent with more than 95% of survival, the long-term complications are frequent. A gastro-oesophageal reflux is found in 26 to 75% of the cases, responsible for peptic oesophagitis, anastomotic stenosis and Barrett's oesophagus, risk factor of adenocarcinoma of the oesophagus. A dysphagia is frequently observed on these patients, sometimes several years after the surgery, observed in almost 45% of five-year-old children. Growth retardation is found in nearly a third of these children. Respiratory symptoms are particularly frequent, especially in the first years, associating tracheomalacia facilitating the bronchopulmonary infectious episodes (found in about 30% of 5-year-old children). Esotracheal fistula recurrence is very rare. A deformation of the rib cage is reported in 20%, and a scoliosis in 10% of the patients. However, the quality of life of these patients in the adulthood is good, and influenced by the existence of associated malformations. Even if the current prognosis of oesophageal atresia is good altogether, the frequency of the complications (digestive, respiratory, nutritional, orthopaedic) far from the initial intervention, and the necessity of a surveillance of the secondary oesophageal damages, justifies a systematic and multidisciplinary follow-up until adulthood.

Gastrointestinal symptoms are very frequent in myotonic dystrophy but largely unrecognized. They can be the revealing factors of the disease. We report 2 cases of 10 and 17-year-old children with persistent encopresis starting at the age of 3 and 5 years in spite of laxative treatment. Neurological examination and anorectal manometry provided the diagnosis of myotonic dystrophy. Procainamide treatment was introduced and the digestive symptoms improved. Any child with encopresis should have complete evaluation to rule out the diagnosis of myotonic dystrophy and physicians should look for upper and/or lower gastrointestinal symptoms in every patient with myotonic dystrophy.

d-lactic acidosis is a rare and severe complication of short bowel syndrome in children that may result from important ileal bacterial overgrowth by lactobacilli. Intestinal flora (Lactobacilli) is responsible for the production of d-lactic acid after fermentation of food carbohydrates.We report on the case of a 6-year-old child with a short bowel syndrome treated with both home enteral and parenteral nutrition. The patient suddenly presented with acute neurological symptoms including dysarthria and disorientation. Biological analysis revealed metabolic acidosis, increased plasma d-lactic acid assessed by organic acid chromatography analysis and a very important increase in expired hydrogen during glucose breath test. Lactobacillus fermentum (known to produce d and L isomers of lactic acid) was isolated in the gastric liquid and rectal swabs. Clinical and biological evolution was rapidly favourable after treatment with intravenous sodium bicarbonate, antibiotic therapy and interruption of enteral nutrition.d-lactic acidosis should be suspected when neurological symptoms occur in a child with short bowel syndrome. They can be prevented by treating intestinal bacterial overgrowth.

Necrotizing enterocolitis is seldom observed in full-term, or near term newborns. We report on two infants born after 36 weeks of gestation who presented with necrotizing enterocolitis after surgery for gastroschisis. Both patients had been formerly weaned from parenteral nutrition and fed thereafter with hydrolyzed cows' milk protein formula. At the age of 1.5 and 4.5 months respectively, the patients presented clinical and radiological signs of necrotizing enterocolitis. Evolution was favourable under medical treatment (parenteral nutrition, progressive refeeding). Post-neonatal digestive symptoms in a child with gastroschisis should prompt the diagnosis of necrotizing enterocolitis in order to allow an early treatment.

Denutrition remains a major concern in hospitalized children. Daily experience suggests that the meals proposed by hospital dietetic service, although well-balanced and in accordance with the recommendations, may be poorly accepted and consumed by children. The aims of this study were to assess the effect of modification of foods offer on energy intakes as well as nutriments and minerals and trace elements in hospitalized children.During a 1-month period, 25 consecutive children (range 4-17 years; 13 girls), hospitalized in our pediatric department were included in the study (reasons for hospitalisation comprised: medical reasons [n=7], orthopedic problem [n=16] or surgery [n=2]). They had no restricted diet and received the usual pediatric hospital feeding according to the French recommended dietary allowances (RDA) (D1). They were compared to 21 children--matched for age, sex, nutritional status and pathology, hospitalized during the following 1-month period--who received a modified diet (D2), elaborated by dieticians according to the child's preference and excluded or limited food usually nonconsumed by the children. Food consumption was prospectively measured for 24h by analysis of the nonconsumed foods, as well as browsing and extra food brought by the family. Analysis of energy, carbohydrate, lipid, protein, iron and calcium intake was made using Bilnut 3 software (Nutrisoft, France).D2 covered 119+/-37% of the median energy needs versus 89+/-37% for D1 (p0.05). The median energy needs were more often reached with D2 as compared to D1 (62% versus 32%, p0.05). Protein intake was high in both groups, more importantly with D2 (266+/-111% of RDA versus 193+/-77% with D1, p0.05). We observed no difference between the 2 diets in regards of fat/carbohydrate balance and iron intake. Calcium intake was increased with the adapted diet: 68+/-26% of RDA with D2 versus 49+/-26% with D1 (p0.01).Adapting food offers to preference influences food and caloric intakes in hospitalized children. This could be an efficient strategy to prevent acute undernutrition in hospital.

Gastro-oesophageal reflux (GOR) is a physiological event defined as flow of gastric content into oesophagus. GOR is frequent in infants commonly subjected to regurgitation. While this symptom usually disappears within the first year of life, there is evidence that some symptoms may persist during childhood. In non complicated GOR, no investigation is indicated. PH-metry is only indicated in case of doubtful diagnosis or extradigestive manifestation. Upper gastro-intestinal endoscopy is indicated when oesophagitis is suspected. First intention treatment is no intervention or dietetic measures. Thickened feeding reduces symptoms such as regurgitation but does not influence GOR. Except for cisapride which use is nowadays very limited, no prokinetics have demonstrated their efficacy on GOR. Anti-secretory drugs should be restricted to the treatment of oesophagitis. Investigations are necessary before prolonged use.

Gastrostomy is frequently used in clinical practice for drug administration. However modalities of drug administration via a gastrostomy device have been poorly studied and remain uncodified.To assess the mode of administration of drugs as well as errors associated with the use of a gastrostomy devices for drug delivery in children.Mode of administration of drugs was studied in 109 children (mean age 8.4+/-5.5 years, 72% neurologically impaired, 41% institutionalized children). A questionnaire was filled in by parents and/or caregivers. Errors of administration were classified as follows: galenic, due to preparation, physico-chemical interaction, lack of flushing the tube. Factors influencing the occurrence of errors were studied: living at home or in an institution, underlying disease, number of drugs administered via gastrostomy device.Errors were frequently observed: galenic (47%), due to preparation (42%), physico-chemical interaction (51%), lack of flushing (10%). Errors occurred more frequently in institutionalized children compared to children living at home (78 versus 25%, P0.0005). Galenic errors were more frequent in neurologically impaired children (57 versus 30%, P0.005).Many medications are administrated via gastrostomy tube in children. Errors are frequently observed and potentially dangerous.

The aims of this work were to assess timing of complementary feeding in infants and to precise the underlying factors that may cause inappropriate complementary feeding.A cohort of 167 newborns, born in the same maternity ward during a 6 week-period, was prospectively analyzed. Only healthy neonates were included in the study. A phone questionnaire was filled at 4 and 6 months of age to evaluate modality of complementary feeding. Multivariate analysis (segmentation tree, analyse by multiple correspondence) was used to study factors associated with inappropriate diversification.Out of the 167 neonates included in the study, 132 mothers could be contacted at 4 months and 116 at 6 months of age. Sixty-seven per cent of mothers started breast feeding at birth. Among these, 33% still breastfed -at least partially- at 4 months and 17% at 6 months. Fifty-two percent of mothers started complementary feeding before 4 months, and 24% of infants received gluten at 4 months of age. Multi-gravida mothers, mothers aged more than 35 years old and mothers who gave infant or follow-up formulae before 4 months, started complementary feeding significantly earlier (P0.05). Infants who were formula fed received more frequently complementary feeding before the age of 4 months than breast fed infants (57% vs 33%, P0.05).Our study showed that half of infants were introduced solid food too early and allowed to identify a population at risk that could benefit from nutritional intervention programs.

The aims of this study were to assess the prevalence of malnutrition in a pediatric population hospitalized in a French regional hospital and to evaluate the influence of type of hospital unit (pediatric or not) in the screening and the management of malnutrition.This one-day cross-sectional survey was performed in three different seasons during 2003. Every child aged 2 months to 16 years old, hospitalized for more than 48 hours was included. Weight for height, Z-score and Body Mass Index Z-score were used for nutritional assessment. Type of hospitalisation unit, date of admission, associated diagnosis, screening and treatment of malnutrition were also taken into account.Two hundred and eighty hospitalized children were undernourished (11%) and thirty-one children were obese (11%) with no difference in prevalence of malnutrition between pediatric and non-pediatric units. At the time of the study, malnutrition was recognized in one third of the children, at a similar rate whatever the type of hospitalized unit. The children hospitalized in pediatrics wards benefited more frequently from nutritional intervention, i.e. dietician care (43 vs. 16% P0.01).Prevalence of malnutrition in hospitalized children is low and the same in pediatric or non-pediatric units. Screening of malnutrition remains unsatisfactory in hospital. However, malnutrition is more frequently treated in pediatric unit compared with non-pediatric unit.

Cystic fibrosis (CF) is characterized by deteriorating lung function and mal-digestion, which result in growth failure and/or under-nutrition. Several factors, alone or combined, contribute to malnutrition in CF: poor energy intake, elevation of energy loss as a result of malabsorption, increasing resting energy expenditure due to genetic mutation and/or pulmonary exacerbation. Several techniques have been used to assess energy expenditure and physical activity in order to better understand mechanisms of malnutrition in CF and follow therapeutic interventions. Indirect calorimetry (IC) studies have shown that resting energy expenditure (REE) was 10-22% higher than predictive values. This increase could be attributed to chronic inflammation as a result of Pseudomonas aeruginosa (PA) infection. Indeed, intravenous antibiotic therapy decreases REE. Doubly labelled water technique and heart rate monitoring calibrated against IC techniques shows that total energy expenditure (TEE) was not different than in healthy children. Physical activity level assessed by the ratio TEE-REE is also not different between CF of healthy children. Recently, new accelerometry technics, easier to use and less invasive have been successfully used in order to assess physical activity level in CF. Precise and ambulatory assessment of energy expenditure and physical activity permit to check and adapt dietary allowances in CF. These techniques could be simultaneously used and be helpful to assess efficacy of intervention studies.

Bronchopulmonary dysplasia remains a frequent complication of extreme prematurity. In preterm neonates catch-up and pulmonary alveolar growth occur during the first two years of life. However 10 to 25% of preterm infants with bronchopulmonary dysplasia are under-nourished after two years of age, and 30 to 60% of them also suffer from persistent airway obstruction, hyperinflation and bronchial hyperreactivity. Recommendations on nutritional requirements in this population are not yet clearly defined, but an adequate nutritional status in prenatal and early postnatal period can have long-term consequences on brain and lung development. There are a few randomised trial of nutrition for preterm infants with bronchopulmonary dysplasia after discharge. Caloric and protein requirements in this population are probably higher than in full-term infants. Moreover there are potential benefits in using specific nutrients: supplementation with long chain polyunsaturated fatty acids could decrease lung inflammation injuries, glutamine is the main source of energy of pneumocyte, vitamin A is essential for lung development, inositol is necessary for surfactant synthesis, vitamin E and selenium have anti-oxidant effects. Controlled nutritional trial are needed with a long term follow-up in late childhood in order to test their effects on growth and pulmonary status.

Cases of cow's milk protein allergy have been occasionally reported after neonatal intestinal surgery.To measure the prevalence of cow's milk protein allergy (CMPA) following neonatal intestinal surgery.The files of all children who underwent intestinal surgery in the neonatal period over a four-year-period were reviewed. The diagnosis of CMPA was made on the association of one or several symptoms suggesting food allergy after the introduction of cow's milk protein in the diet, the disappearance of the symptoms after exclusion of cow's milk protein from the diet and their reappearance after reintroduction of cow's milk protein.During the study period, 251 neonates underwent an intestinal surgery. Among them, 11 babies (4.3%) developed CMPA. None of them had a medical history of family atopy. Moreover, while 5 children were fed with a diet containing cow's milk protein before surgery: none of them presented initially with symptoms suggesting CMPA before intestinal surgery. Small intestine suffering was observed during operation in seven of 11 patients. No specific neonatal digestive disease or malformation was associated with CMPA. The signs revealing CMPA were primarily digestive : diarrhoea (N =3), vomiting (N =4), abdominal distension (N =2), colic or anorexia (N =2). Casein specific immunoglobulin E were present in nine of ten cases, alpha lactalbumin and/or beta lactoglobulin specific immunoglobulin E were present in six of ten cases. Prick test were performed in three children and were positive.The high prevalence of CMPA among these patients with no risk factors of allergy raises the question of the role of neonatal intestinal surgery in developing food allergy. These data should be confirmed by prospective case-control studies. They underline the interest to evoke the diagnosis of CMPA when digestive symptoms occur after milk protein introduction in children undergoing neonatal intestinal surgery. Breast feeding or milk protein hydrolysate formula should be used for refeeding these patients.

We report the fifth case of neonatal form of type C2 (NP-C2) Niemann-Pick disease with early and fatal respiratory distress. Eleven families presenting such cases are known to date in the world. Since December 2000, isolation of the underlying gene HE1/NPC2 and its mutations has allowed major advances in diagnosis.Elisa was born in May 2000. NP-C2 disease was associated with severe respiratory distress leading to death at the age of four months. On the next pregnancy in September 2000, prenatal diagnosis was performed by means of biological tests that required four weeks response time. In December 2000, isolation of the HE1/NPC2 gene located to 14q24.3 and of some of its mutations allowed to characterize the patient as being homozygote for the nonsense mutation E20X. On the the two next pregnancies, prenatal diagnosis was performed at 12 SA, in 48 hours, by the means of mutation analysis. The last fetus was heterozygote for the mutation E20X, allowing the birth at term of a healthy male newborn baby.Niemann-Pick type C disease is a rare lysosomal lipid storage disease with severe prognosis. It is characterized by abnormalities of intracellular transport of endocytosed cholesterol. Diagnosis relies on biological tests that require cultured cells. Genetic heterogeneity defines two different genetic complementation groups C1 and C2. Severe and early respiratory distress is more likely to be associated with the rare type C2. Since December 2000, after identification of the disease-causing mutations in the proband, mutation analysis of gene HE1/NPC2 on direct chorionic villus samples allows early and fast (48 hours) prenatal diagnosis.

Iodine deficiency is responsible for a higher mortality and morbidity in neonates and infants. It has not yet disappeared in European countries, especially in Southern and Eastern Europe.The present study aimed at evaluating the status of iodine nutrition of infants living in the North department (France) and at studying risk factors for iodine deficiency.The study was conducted in primary health care centres in 160 healthy infants aged ten days to six years (mean +/- SD: 17.7 +/- 2.5 months). Data included: familial thyroid disease history, type of feeding at inclusion, timing of introduction of complementary foods, nutritional status (weight, height, head and arm circumference), as well as maternal education level and family socio-economical status. Iodine status was assessed by urinary iodine excretion.Urinary iodine concentration ranged from 4 to 1042 microg/l (median +/- SD: 195,5 +/- 21,6 microg/l). Thirty-eight (24%) of 160 children were iodine deficient (urinary iodine100 microg/l): mild iodine deficiency (50-99 microg/l: 17%), moderate iodine deficiency (20-49 microg/l: 5%), severe iodine deficiency (20 microg/l: 2%). No relationship was found between iodine status and age, sex, geographic origin of the children, as well as social and occupational group of the parents. Breast-feeding did not prevent from iodine deficiency. Iodine status did not differ between the cow's milk fed group and the group that was not fed cow's milk. Formula feeding was associated with iodine deficiency (p = 0,02).Prevalence of severe iodine deficiency was very low in this population. However, iodine status was not optimal.

Non invasive tests are available and accurate for the diagnosis of H. pylori infection in children. They are safer and cheaper than endoscopy. Peptic ulcer and severe gastro-intestinal lesions associated with H. pylori infection are rare in childhood. However since the resistance to antibiotics is steadily increasing, biopsies are still required to assess sensitivity of germs to antibiotics. Search of H. pylori infection should be limited to the children presenting digestive symptoms severe enough to justify endoscopy and treatment.

Acute gastroenteritis remains a frequent illness in infants and children with still important morbidity and mortality rates. Oral rehydratation solutions (ORS) and early refeeding are the main recommendations. Indication of drugs remains limited.To evaluate the management of acute diarrhea by private practice pediatricians of France.A questionnaire concerning ORS, dietary formula, antidiarrheal diet, antibiotherapy, antidiarrheal drugs was sent to all 2907 private pediatricians of France.Six hundred twenty-nine questionnaires were analyzed (22%). Three hundred and ninety-seven pediatricians (63%) prescribed systematically an ORS, 294 (47%) changed formula, 412 (66%) prescribed a regimen. Antibiotic was prescribed after coproculture (81%), when glairy and bloody diarrhea (65%), associated infectious disease (63%), toxi-infectious syndrome (42%) or immunodeficiency were present (28%). Most pediatricians (97%) prescribed at least one drug: diosmectite (84%), Lactobacillus acidophilus (63%), Saccharomyces boulardii (62%), racecadotril (62%), loperamide (28%), attapulgite de Mormoiron (26%), nifuroxazide (20%). Drugs were prescribed more often for their effectiveness than for comfort.This study demonstrates the discrepancies that remain between recommendations and practical care in the treatment of acute diarrhea in children. Private French pediatricians often prescribe drugs.

Hirschsprung's disease (HD) involves the entire colon in less than 5% of cases, and the association of extensive HD with intestinal malrotation is very rare. This association of symptoms may delay both diagnosis and treatment. An infant presented with an intermittent occlusive syndrome that began neonatally. Intestinal malrotation was diagnosed radiologically, and treated surgically when the child was 2 months old. However, a chronic occlusion persisted. Biopsies of the rectum and the appendix demonstrated an absence of neurons in intestinal plexi. When the child was 17 months old, ileostomy and surgical excision of the segment affected by HD (the colon and terminal ileum) were performed. An ileoanal anastomosis was performed at the age of 29 months, with favorable outcome. The persistence of symptoms of intestinal occlusion after attempted treatment of intestinal malrotation must therefore suggest the possibility of associated HD in a young child.

Detection of a gastroesophageal reflux in the aetiology of recurrent respiratory diseases is the main indication of continuous gastroesophageal pH-metry in children. The aim of the study was to measure the diagnostic value of a daytime esophageal pH monitoring in children with recurrent respiratory diseases.One hundred seventeen continuous esophageal pH monitoring of 5 +/- 3 year-old children presenting recurrent respiratory diseases have been reviewed. For each record, an analysis of the total record period, then the diurnal record, then the nocturnal record period was performed. The reflux index, the number of reflux per hour, and the number of long lasting reflux (5 min) per hour were compared between different periods (total, diurnal, and nocturnal).For the reflux index, the sensibility, the specificity, the positive predictive value and the negative predictive value of the awake period in comparison with the continuous 24 h record, considering the same standards for both periods, were 97%, 46%, 72% and 92% respectively. The ROC graph analysis showed that the cut-off adaptation for the reflux index and for the number of reflux per hour, did not allow to improve the day pH-metry performance, since sensibility and specificity moved respectively from 66% to 56% for reflux index, and from 75% to 56% for the number of reflux per hour.In children explored for recurrent respiratory diseases, the night record has a bad diagnostic value and a negative diurnal record is strongly predictive of absence of pathological gastroesophageal reflux in these children. Because of the absence of paediatric specific standards for this disorder, it is not possible to reduce the recording time to the diurnal period.

Esophageal manometry has been increasingly used in children allowing better description of esophageal primary disorders as partial achalasia. The aim of this retrospective study was to describe clinical manifestations of partial achalasia, to look for their specificities and to follow clinical and manometric evolution in response to treatment.Eighteen patients (mean age four years: range one month-13.5 years) presenting with partial achalasia were examined from 1990 to 1998. The symptomatology leading to esophageal manometry was: dysphagia (n = 9), gastroesophageal reflux (n = 6), swallowing disorder (n = 3). pH-metry (n = 8), esophageal endoscopy (n = 11) and barium transit (n = 12) were also performed.Twelve children were treated with nifedipine, (dysphagia n = 6, gastroesophageal reflux n = 5, swallowing disorder n = 1). At follow-up, a good clinical response was observed in six children while no effect or transient improvement were observed in two and four children respectively. Two of them presented spontaneous clinical resolution of symptoms after nifedipine was stopped but four children needed Heller procedure. Six of 18 patients (dysphagia n = 3, gastroesophageal reflux n = 2, swallowing disorder n = 1) developed achalasia or recurrent symptoms which required Heller surgery. At the first examination, no clinical or manometric features could differentiate these six patients from the remainders who presented a favorable outcome.Esophageal primary disorders as partial achalasia in children are observed in various clinical conditions. The possible development of achalasia and persistence of symptoms in some children justify both attentive clinical and manometric follow-up.

In this paper written by the Groupe francophone d'hépatologie, gastroentérologie et nutrition pédiatriques, recommendations are given on the indications of drugs in infant and child infectious acute diarrhea, based upon the current scientific knowledge on their effectiveness and tolerance. This paper complements an article on nutritional treatment of acute diarrhea written by the Comité de nutrition de la Société française de pédiatrie, and published in the same issue of the Archives de Pédiatrie.

To assess the frequency of acquisition of secondary Helicobacter pylori resistant-strains after a first course of antimicrobial treatment.A retrospective study was performed during the 1994-2000 period, in 15 girls and eight boys, mean age 10.9 +/- 4.8 years (1.4-17 years), with Helicobacter pylori gastritis (culture and antimicrobial susceptibility) presenting a failure of first course treatment, with during one week a proton pump inhibitor and amoxicillin together with either clarithromycin (n = 14) or metronidazole (n = 9). Two endoscopies were performed, the first at the time of diagnosis and the second after the failure of bacterial eradication demonstrated by a positive 13C urea breath test six weeks after the end of treatment. Antimicrobial susceptibility of all Helicobacter pylori strains was tested after each endoscopy and before starting a second course of the treatment.Comparison of antimicrobial susceptibility before and after the first course of treatment showed that Helicobacter pylori strains were all sensitive to amoxicillin, clarithromycin-resistant in eight children (34.7%) before treatment vs 12 (52.1%) after treatment, p = 0.42, ns, metronidazole-resistant in 13 (56.5%) vs 12 (52.1%), p = 0.80, ns, and both clarithromycin and metronidazole-resistant in four (17.3%) vs seven (30.4%), p = 0.63, ns. Among the 14 children treated by a triple therapy including clarithromycin, three (21.4%) developed a secondary resistance to clarithromycin and in one metronidazole resistance was no more detected. Among the nine children treated with a triple therapy including metronidazole, none developed a secondary resistance to metronidazole and one developed a secondary resistance to clarithromycin.This study shows the absence of amoxicillin-resistant strains, a high initial clarithromycin-resistant strains level (primary resistance), increasing after a first course of treatment, and for metronidazole a high initial level of resistance not influenced by treatment. Secondary clarithromycin-resistance of Helicobacter pylori strains following the first course of treatment could account for failure of bacterial eradication and suggests the importance of antimicrobial susceptibility.

Prognosis of extrahepatic biliary atresia depends on an early surgical treatment. This survey studied the delay to surgery of infants treated for biliary atresia and analysed the causes of late diagnosis and referral.Medical files of 21 infants treated for biliary atresia between 1988 and 1998 were retrospectively analysed.Median age at biliary operation was 57 days and did not change during time. In only 3/21 cases, surgery was performed before 45 days of age. The first clinical or biological sign of cholestasis was noted at a median age of 12 days. In eight cases, the first medical visit for cholestasis (median age of 21 days) was not followed by a blood test. In 11 cases, infants presenting with biological cholestasis were referred to hospital more than seven days later. False diagnosis was noted in seven cases and delayed significantly the operation.The delay to surgical treatment is too long and does not decrease whereas a majority of infants visit their physician early. Medical information is mandatory for all physicians taking care of infants.

Anastomotic stricture is the most common complication following the surgical repair of esophageal atresia, and is usually treated by esophageal dilation.The aims of this study were to assess in an infant population operated on at birth for type III or IV esophageal atresia: 1) the frequency of esophageal stenosis following the repair of esophageal atresia, and associated factors; 2) the efficacy of esophageal dilation by the Savary-Gaillard bougie technique.The medical records of 52 children presenting with esophageal atresia over a 5-year period were retrospectively reviewed. Gestional age and birth weight, duration of mediastinal and transanastomotic drainage, and anastomotic complications including leakage, stricture, and the presence of gastroesophageal reflux were recorded and analysed. Patients presenting with anastomotic stricture were compared with a group of children without stricture. The number of esophageal dilations, their efficacy and the complication rate were analyzed.Anastomotic stricture developed in 20 (40%) of the 50 patients undergoing primary repair for esophageal atresia. The occurrence of anastomotic stricture was related to anastomotic tension during esophageal surgical repair (p0.03). Young children required esophageal dilation at a mean age of 142 days (24-930 days). Stricture resolution occurred after a mean of 3.2 dilations (1-15) over an average period of 7.9 months (range: 0-30 months). Dilation was successful in 90% of the 20 patients. Seven patients required only one dilation. Perforation of the esophagus occurred in one case, and this severe complication led to the death of the child. Esophageal dilation was unsuccessful in two patients, who presented prolonged severe dysphagia.Anastomotic stricture following repair of esophageal atresia is connected with the length of the gap that has to be repaired, and tension during suture. Esophageal dilation by the Savary-Gaillard bougie technique is an effective method for treating esophageal stricture. Several dilations are usually needed before the disappearance of dysphagia.

Heterotopic or aberrant pancreas is a rare congenital anomaly, usually asymptomatic. The preoperative diagnosis is difficult but most cases of gastric ectopic pancreas have a unique appearance that often makes possible a diagnosis in the absence of histologic confirmation. A well-delineated submucosal, firm mass with central umbilication is characteristic of gastric ectopic pancreas. To the best of our knowledge, the association of esophageal atresia and gastric heterotopic pancreas has never been reported previously.We report two cases of heterotropic pancreas associated with esophageal atresia. Both diagnoses were incidental findings and concerned children operated on at birth for esophageal atresia. Although a definitive diagnosis is histologic, the endoscopic appearance made it possible to maintain this diagnosis.Some symptoms have been attributed to ectopic pancreas, and malignant degeneration has been reported in adults. Management continues to be debated: some authors recommend surgical resection while others, as we do, prefer initial therapeutic abstention.

Helicobacter pylori (H. pylori) colonizes the human stomach, especially during childhood. H. pylori gastritis, in the absence of duodenal ulcer, does not appear to be associated with specific symptoms. After eradication of H. pylori infection, abdominal pain is improved only in children with duodenal ulcer. Children with H. pylori gastritis cannot be distinguished from uninfected children on the basis of initial symptoms. However, although not demonstrated, a relationship between H. pylori and recurrent abdominal pain might exist since some studies showed that H. pylori-infected children present more frequent pain related to meals or ulcer-like symptoms. These discrepancies could be explained by the fact that H. pylori is probably not a frequent cause of recurrent abdominal pain. The use of refined clinical characteristics of abdominal pain could be of help identifying a subgroup of patients with abdominal pain in whom H. pylori infection needs to be sought and treated. Recent pediatric consensus conferences recommend testing for H. pylori infection by endoscopy only those patients presenting symptoms suggestive of an organic origin.

Gas in the gut derives from swallowed air, intra-luminal production and diffusion from the blood. Excessive swallowed air may cause pathologic aerophagy.This report describes four children aged from 3 to 12 years with pathologic aerophagy due to excessive air swallowing. One of them had a "Gas Bloat Syndrome". Clinical presentation was very incongruous. However, the clinical features were characteristic: abdominal distention increasing throughout the day, associated with visible and often audible air swallowing and excessive flatus. The questioning and clinical examination helped for diagnosing. Medical symptomatic treatment was associated with a psychotherapy approach.A better recognition of this condition might contribute towards earlier diagnosis.

New techniques for the measurement of energy expenditure of children have been developed in recent years, which can be applied in free-living conditions: heart rate monitoring, double labelled water method, accelerometry. This paper presents the principles, advantages and disadvantages of these techniques.

Trichobezoars are composed of hair or fibres. The typical patient presenting with a trichobezoar is an adolescent girl experiencing mental disturbance or retardation.Three girls with trichobezoars were seen. Two of them, 4 and 15 years old, had serious digestive antecedents (corrosive oesophagogastritis and oesophageal atresia, respectively) and had undergone previous surgery. The third was a 13-year-old mentally retarded girl. In two cases, an enzymatic dissolution trial was unsuccessful, requiring secondary surgical removal after, in one case, ineffective gastroscopic removal complicated by an oesophageal perforation. The third child had an initial operative removal.Serious digestive antecedents may favour bezoars, a diagnosis that must be evoked in such patients presenting with chronic digestive symptoms. Enzymatic dissolution is ineffective for large bezoars, and gastroscopic removal carries some risks such as perforation or intestinal obstruction. Operative removal is usually indicated. Psychiatric follow-up is needed to prevent this complication in children with serious digestive antecedents and to reduce the risk of recurrences.

Long term follow-up of children with esophageal caustic stenosis is not well known. The aim of the present study was to describe functional, organic and psychological, as well as social consequences.Thirty-four children with a mean age of 3 years and 7 months +/- 3 years and 2 months (ranges: 1 month-14 years and 3 months) were included in a longitudinal study. Various parameters have been studied: treatment, functional symptoms, nutritional status (weight/height, body composition) and psychological and social consequences. chi 2 and Mann-Whitney tests were used for statistical analysis.Twenty-one patients have been treated by mechanical dilatations whereas surgery was performed in 12 children; the mean number of dilatations per child was higher in patients treated by dilatations (21 +/- 17 vs 14 +/- 16; P0.05). The frequency of dysphagia was not different in patients with colon interposition or not (69% vs 53%; P = 0.1). Nutritional status was not affected by the presence of esophageal caustic stenosis. Psychological and social consequences were characterized by scholastic difficulties, anxiety and severe depression. One case of suicide was observed.Children with caustic stenosis should be followed for a long period of time. A multidisciplinary approach is necessary, taking into account medical, social and psychological consequences.

Fetal alcohol syndrome is quite common in our region (incidence: 1/700 live births). It usually associates facial dysmorphism, intra-uterine growth retardation and mental delay.Jonathan, born to an alcoholic mother, presented a typical dysmorphy of fetal alcohol syndrome and a low inserted umbilicus. A small bowel atresia was discovered at the third day of life and operated on.Although never been previously described, this association suggests a common embryological origin between fetal alcohol syndrome, small bowel atresia, and umbilical abnormality.

Upper gastrointestinal endoscopy is frequently used in the neonatal period. The aim of this study was to assess the frequency of the different lesions occurring as well as to precise indications of upper gastrointestinal endoscopy in neonates.A retrospective study including 107 neonates referred between October 1986 and April 1995 has been achieved in the pediatric gastroenterology unit of the Lille University Hospital. Various factors were analysed: gestational age, sex, reasons for endoscopy and macroscopic lesions observed. Three groups were constituted according to macroscopic findings; group I: normal aspect (n = 22); group II: isolated esophagitis (n = 27); group III: esogastritis or gastroduodenitis or esogastroduodenitis (n = 38). Chi 2 test was performed for statistical analysis.Signs recalling esophagitis (cry during feeding) were more frequent in group II than in group III: 37% vs 13% (P0.03). The neonates undergoing endoscopy for life-threatening events were more frequent in group I than in group II or III, respectively: 59% vs 15% (P0.01) and 59% vs 8% (P10(-4). Upper gastrointestinal endoscopy led to a precise diagnosis in 80% of the neonates. However 95% of those examined for hematemesis presented macroscopic lesions.Hematemesis and suspicion of esophagitis are good indications for upper gastrointestinal endoscopy in neonatal period. In life-threatening events and suspicion of pyloric stenosis, upper gastrointestinal endoscopy is only complementary of more contributive other examinations.

The aim of the study was to evaluate the prevalence of gastroesophageal reflux and abnormalities of esophageal motility in a population of neonates referred for apparently life threatening event (ALTE) and presenting vagal hyperreflectivity.The study included 17 infants, who were examined after an ALTE. They were admitted at a mean age of 11.7 weeks (range 1-40 weeks). Vagal hyperreflectivity was confirmed in each infant by oculocardiac reflex. Before treatment, 24-hour intraesophageal pH-monitoring and esophageal manometry were performed.pH-monitoring and esophageal manometry were both normal in only two patients. pH-monitoring showed pathological reflux (% of time with pH4 more than 4.8%) in 10/17 (59%) patients. Manometric studies showed esophageal dysmotility in 12/17 (71%) of patients. Hypertensive lower sphincter was noted in 11/17 (65%) infants. Patients with normal manometry were older than patients presenting with esophageal dysmotility (P0.05).This study shows a high frequency of gastroesophageal reflux and dysmotility in infants with vagal hyperreflectivity. Hypertensive lower esophageal sphincter as well as vagal hyperreflectivity may correspond to dysmaturity of autonomous nervous system and facilitate the occurrence of ALTE.

Autoimmune hepatitis (AIH), usually chronic hepatitis, can be revealed by an acute episode of hepatic failure not easily treatable.A 4 year-old boy presented with severe acute hepatic failure (AHF) without hypergammaglobulinemia, revealing AIH. A triple immunosuppressive treatment (prednisolone, azathioprine, ciclosporine) was started when clinical and biological signs worsened (prothrombin time 18%, factor V 32%). Liver functions significantly improved within 10 days, although complications due to intensive immunosuppression occurred (Candida septicemia).AIH must be evocated in each case of AHF. Some observations of AIH treated with ciclosporine are published but protocols of its administration are variable: ciclosporine is used alone or associated with other drugs, in first intention or secondarily, when the classical treatment is contra-indicated or fails. Controlled studies are needed to precise ciclosporine indications in AIH and to propose the best protocol.

Orthotopic liver transplantation (OLT) is an effective treatment for patients with cystic fibrosis end stage liver disease, especially those with only mild pulmonary involvement. Long-term follow-up in such transplanted patients is still lacking.A 15-year-old girl with cystic fibrosis received an OLT because of severe decompensated cirrhosis. She had been colonized by Pseudomonas aeruginosa for 3 years and had pancreatic insufficiency; she also had mild glucose intolerance. Postoperatively she developed diabetes mellitus requiring insulin therapy for 9 months. Oral cyclosporin was poorly absorbed so that she was given a new emulsion of cyclosporin (Neoral) that was better absorbed. A rapid pubertal catch-up was obtained but the patient remained colonized by Pseudomonas aeruginosa.This 3-year postoperative follow-up confirms that OLT can represent a good alternative in those patients with severe liver disease and mild pulmonary involvement.

Based on results of epidemiological studies, dorsal or lateral sleeping positions are now recommanded in the prevention of sudden infant death syndrome (SIDS). This raises an ethical question about the attitude towards the ventral positioning therapy for gastroesophageal reflux (GOR). The consensus conference considers that the ventral position should only be recommanded in GOR when the benefit appears to outweigh the risk of SIDS that it induces. The conference proposes that for infants with simple uncomplicated reflux, sleeping in the prone position should not be introduced in the first line treatment. Prone positioning should be restricted to complicated cases resistant to dietary and medical measures.
