Abstract
OBJECTIVES During the past few years, multislice computed tomography coronary angiography has made great progress in terms of spatial and temporal resolution. Results on detection and quantification of stenoses are excellent. We found interesting reporting its achievements in aneurismal coronaropathies such as the Kawasaki disease. METHODS We searched for young adults with Kawasaki disease who had a multislice computed tomography coronary angiography available. Several hospitals in the Paris area have been contacted and only two observations have been kept. RESULTS Computed tomography provided higher performance than coronarography for the measurement of the real diameter of an aneurism taking into account the mural thrombus, evaluation of its links with the collateral branches and the other aneurisms, assessment of the development of recanalized vessels and the degree of development of collateral vessels, and visualization of non-circulating aneurisms which were not detected with coronary angiography. In addition, the evaluation of the location and the degree of the stenoses by the computed tomography matched the coronary angiography data. It was not possible to conclude with this observations that the computed tomography is better for the diagnostic of Kawasaki disease. CONCLUSION Multislice computed tomography coronary angiography will be likely more and more used to detect and follow coronary anomalies in case of Kawasaki disease among teenagers and young adults. It is recommended for monitoring medium or large aneurisms in order to evaluate their progression to stenosis.

Abstract
Determining total energy expenditure (EE) in children under free-living conditions has become of increasingly clinical interest. The aim of this study was to compare three different methods to assess EE triaxial accelerometry (TriTrac-R3D; Professional Products, Division of Reining International, Madison, WI, USA), activity diary and heart-rate (HR) monitoring combined with indirect calorimetry (IC). Twenty non-obese children and adolescents, aged 5.5 to 16.0 years, participated in this study. Results from the three methods were collected simultaneously under free-living conditions during the same 24 h schoolday period. Neither activity diary (5904 (SD 1756) KJ) NOR THE TRITRAC-R3D (6389 (sd 979) kJ) showed statistical differences in 24 h total EE compared with HR monitoring (5965 (sd 1911) kJ). When considering different physical activity (PA) periods, compared with HR monitoring, activity diary underestimates total EE during sedentary periods (P<0·001) and overestimates total EE and PA-EE during PA periods (P<0·001) because of the high energy cost equivalence of activity levels. The TriTrac-R3D, compared with HR monitoring, shows good agreement for assessing PA-EE during PA periods (mean difference +0·25 (sd 1·9) kJ/min; 95 % CI for the bias -0·08, 0·58), but underestimates PA-EE and it does not show good precision during sedentary periods (-0·87 (sd 1·4) kJ/min, P<0·001). Correlation between the vector magnitude generated by the TriTrac-R3D accelerometer and EE of activities derived from HR monitoring is high. When compared with the HR method, the TriTrac-R3D and activity diary are not systematically accurate and must be carefully used for the assessment of children's EE depending on the purpose of each study.

Abstract
Interventional endoscopy concerns the therapeutic acts carried out by endoscopic way at the level of the digestive tract. It is realized under general anaesthesia and it has profited from recent progress of the material (endoscopes and accessories). Some acts are realized in a current way in paediatrics: extraction of foreign body, dilation of oesophageal stenosis, gastrostomy. Other indications are rarer. In these cases, interventional endoscopy is usually done with the collaboration of the adult endoscopists, whose field of activity in interventional endoscopy is far much broader.

Abstract
BACKGROUND AND STUDY AIMS Mitomycin C is an antiproliferative agent that has been used successfully as an adjunct treatment in ophthalmological procedures, in the management of laryngeal and tracheal stenosis, and more recently to prevent the recurrence of caustic esophageal strictures in children. The aim of this study was to assess the efficacy and safety of local application of mitomycin C to refractory esophageal strictures in children. PATIENTS AND METHODS We performed a preliminary prospective study of local application of mitomycin C in four children, aged between 1 year and 6 years, who had refractory esophageal strictures. Two of the children presented with strictures caused by caustic ingestion and the other two children had anastomotic strictures following surgical repair of congenital esophageal atresia. The patients had required between four and ten esophageal dilations over a 5-24-month period before mitomycin C application. After an endoscopic dilation, mitomycin C was applied onto the dilation wound using a rigid endoscope. RESULTS No complications were observed after the procedure. One child required a second application of mitomycin C 2 weeks after the first application because of recurrence of dysphagia. All the children remained asymptomatic and none of them required further dilation over a mean follow-up period of 24 months. Radiological control examinations revealed that there was no recurrence of the esophageal strictures and esophageal biopsies performed during follow-up showed no signs of dysplasia. CONCLUSIONS Local application of mitomycin C is a potential alternative to iterative dilations, surgery, or stent placement for the treatment of refractory esophageal strictures in children. However, prospective, long-term assessment of outcomes is needed before any definitive conclusion can be drawn about the usefulness of mitomycin C in these patients.

Abstract
Major depression IMD) is highly prevalent in the general hospital and adds a considerable burden to affected patients, but remains under detected and under treated. In an attempt to improve this situation, existing guidelines on MD were retrieved, systematically evaluated with the instrument AGREE (Appraisal of guidelines for research and evaluation), and adapted to the needs of the general hospital. These guidelines were made available on intranet, and actively implemented in two wards, where their impact on clinical practice was evaluated.

Abstract
UNLABELLED 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. PATIENTS AND METHODS 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. RESULTS 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 (P<0.05). Infants who were formula fed received more frequently complementary feeding before the age of 4 months than breast fed infants (57% vs 33%, P<0.05). CONCLUSION 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.

Abstract
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.

Abstract
OBJECTIVES 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. PATIENTS AND METHODS 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. RESULTS 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% P < 0.01). CONCLUSION 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.

Abstract
Chronic pulmonary infection by Pseudomonas aeruginosa is observed in 50% of patients with cystic fibrosis and requires the use of recurrent intravenous therapy. A decrease of resting energy expenditure (REE) and an increase of physical activity (PA) after intravenous anti-P. aeruginosa therapy (IVAT) is observed while total energy expenditure (TEE) does not change. A decrease in the energetic cost of physical activity (ECPA) could be hypothesized but has never been studied. Our aim was to assess the evolution of ECPA after home IVAT in both standardized condition at hospital and in free-living condition twice before and after IVAT. Sixteen CF patients (nine boys, seven girls) chronically colonized by P. aeruginosa with a mean age of 12.1+/-2.3 years (range 7.1-14.6) were studied before and after IVAT. Each patient passed throughout a visit in hospital: weight, height and fat-free mass were measured. Then, energy expenditure (EE) measured by indirect calorimetry and heart rate (HR) were simultaneously recorded at different levels of PA: REE, and at different intensity of physical activities on a cycloergometer using an incremental increase of the power brake force. Physical activity energy expenditure (PAEE) was computed in laboratory condition using PAEE=EE-BEE (basal energy expenditure). Linear regression between PAEE and power brake force was fitted for each patient before and after IVAT. ECPA in standardized conditions was compared at different range of power brake force using area under the curve (AUC). After coming back at home, 24 h TEE using the heart rate monitoring technique and PA by triaxial accelerometry were simultaneously measured in free-living condition for 24 h during a school day. ECPA in free-living conditions was compared by the ratio PAEE:PA where PAEE=DEE-REE (DEE=daily energy expenditure). After IVAT, median AUC between 60 and 90 W in standardized condition decreased significantly by -15.4% (median 14.9, range 8.8-30.3 vs. median 12.6, range 8.5-17.6; P<0.05, Wilcoxon rank test) while the decrease for lower range of power work load did not reach significance. Spearman correlation was significant between variations of forced expiratory volume in 1 s and variation of AUC at 30-60 W before and after IVAT in standardized condition. In free-living conditions, ratio PAEE/PA did not vary significantly (median 3.4, range 1.6-6.4 vs. median 2.8, range 1.4-4.8; NS). Our data demonstrate a decrease of ECPA after IVAT in standardized conditions for moderate level of PA (60-90 W), but not in free-living conditions. The decrease of ECPA was probably due to a decrease in the energetic cost of breathing after IVAT, that is particularly relevant to promote PA in CF patients.

Abstract
UNLABELLED Cases of cow's milk protein allergy have been occasionally reported after neonatal intestinal surgery. AIM OF THE STUDY To measure the prevalence of cow's milk protein allergy (CMPA) following neonatal intestinal surgery. PATIENTS AND METHODS 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. RESULTS 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. CONCLUSION 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.

Abstract
BACKGROUND AND STUDY AIMS A survey of sedation usage in children undergoing diagnostic upper gastrointestinal endoscopy was undertaken among the members of the Francophone Pediatric Hepatology, Gastroenterology, and Nutrition Group. MATERIALS AND METHODS A questionnaire regarding the mode of sedation used for noninterventional upper gastrointestinal endoscopy, relative to the patient's age and clinical condition, was sent to all members of the Group. The sample included 51 pediatric endoscopy centers (33 university hospitals, eight general hospitals, and 10 private practices). RESULTS The response rate was 84 % (43 of 51) overall, and 100 % for university hospitals. Forty percent of the pediatric endoscopy centers routinely offered children and/or parents a choice between general anesthesia and conscious sedation. Only 14 % of the pediatric endoscopists surveyed routinely conducted upper gastrointestinal endoscopy under general anesthesia, irrespective of the patient's age or the indication for endoscopy. Patients under the age of 6 months underwent endoscopy as follows: 35 % under conscious sedation, 22 % under general anesthesia, and 43 % with no sedation. After the age of 6 months, endoscopy was conducted as follows: 45 % under conscious sedation, 47 % under general anesthesia, and 8 % with no sedation. Midazolam was the most common drug used for conscious sedation. In patients aged 3 - 5, inhaled nitrous oxide was used instead of midazolam for conscious sedation in 12 % of pediatric endoscopies, and local anesthesia with lidocaine (Xylocaine) in 24 %. In those over the age of 5, the proportions of centers using inhaled nitrous oxide and lidocaine increased to 19 % and 42 %, respectively. CONCLUSIONS These results clearly show that the mode of sedation used in noninterventional upper gastrointestinal endoscopy in the pediatric age group is highly variable.

Abstract
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.

Abstract
Two psychrotrophic bacterial strains isolated from Antarctic seawaters were investigated for their capability to degrade commercial diesel oil. The efficiency of hydrocarbon utilization was studied at 4 and 20 degrees C over a period of two-months. Strains were cultured in a mineral liquid medium supplemented with diesel oil as the sole source of carbon and energy. The viable counts for the bacterial abundance estimation and the culture extractions for the subsequent gas-chromatographic analysis were carried out simultaneously. The biodegradation efficiency was higher at 20 degrees C than at 4 degrees C for both strains and the decrease in hydrocarbon concentrations reached more than 85% after 60 days of incubation at 20 degrees C. Our results suggest the possible exploitation of these two bacterial strains in future biotechnological processes, directly as field-released micro-organisms both in cold and temperate contaminated marine environments.

Abstract
BACKGROUND AND STUDY AIMS The aims of this study were to determine the prevalence of gastrocutaneous fistula after removal of gastrostomy tubes in children and to identify associated risk factors. PATIENTS AND METHODS The records of children who had undergone removal of gastrostomy tubes between January 1992 and December 2002 were reviewed retrospectively. Persistent gastrocutaneous fistula was defined as the absence of closure of the gastrostomy 1 month after tube removal. Factors that might influence spontaneous closure of the gastrostomy were studied, including age, underlying disease, nutritional status, type of gastrostomy, replacement of the gastrostomy tube by a button, abdominal wall thickness, duration of gastrostomy tube or button placement, and complications related to the presence of the gastrostomy (infection, granulation tissue). RESULTS A total of 44 patients were included in the study (mean age 20 months, range 1 day to 14 years). Of these, 28 had undergone percutaneous endoscopic gastrostomy and 16 surgical gastrostomy. The mean time to spontaneous closure was 6 +/- 7 days. Persistent gastrocutaneous fistula developed in 11 patients (25 %) and in seven of these patients this required surgical closure (16 %). The mean duration of gastrostomy placement was significantly longer in patients who went on to develop a gastrocutaneous fistula than in patients who did not develop a fistula (39 +/- 19 months vs. 22 +/- 23 months, respectively, P < 0.03). No other significant association was found between the time required for spontaneous closure and the characteristics of patients or the type of gastrostomy. CONCLUSIONS Persistent gastrocutaneous fistula is common after removal of gastrostomy tubes in children. Surgical closure should be considered when a gastrostomy has not closed spontaneously 1 month after removal of the gastrostomy tube.

Abstract
A set of 146 Antarctic marine isolates from the Ross Sea was characterized by a combination of molecular techniques in order to determine the degree of inter- and intraspecific variability. Isolates were analyzed by amplified rDNA restriction analysis (ARDRA) using the tetrameric enzyme AluI, resulting in 52 different groups, corresponding to at least 52 different bacterial species, indicating a high degree of interspecific variability. The phylogenetic position of bacteria belonging to some ARDRA groups was obtained by sequencing of 16S rDNA. Random amplified polymorphic DNA (RAPD) analysis, carried out on the largest ARDRA groups, revealed a high intraspecific genetic variability, too. The analysis of plasmid content revealed the existence of horizontal gene transfer between strains belonging to the same and to different species. A comparison of the whole body of morphological, physiological and biochemical data was finally carried out.

Abstract
INTRODUCTION Exercise testing is useful in the respiratory evaluation of patients with cystic fibrosis. The shuttle walk test (SWT) is a progressive, externally paced, exercise test requiring the subject to walk/run back and forth between two fixed points. The aim is to assess the reproductibility of the SWT in paediatric patients with cystic fibrosis. METHODS This prospective study recruited 31 children with stable disease. The patients performed two SWT one day (SWT 1 and 2) and two others (SWT 3 and 4) within 15 days. Only SWT 2 and 4 were assessed for reproducibility. RESULTS 61% were boys, median age (range): 12.9 (7-18.9) years, median Shwachman score (range): 80 (65-100), median values for FEV1 and FVC (range): 92 (55-154) and 92 (64-140)% predicted, respectively. Median distance for SWT 2-4 (range): 910 (580-1020) and 925 (540-1020) metres. Reproducibility for SWT distance and physical activity measured by an accelerometer is very good (intra-class correlation coefficient=0.90 and 0.92, respectively). SWT distance correlated with physical activity (p=3.10(-4)) and weight (p=0.03). SWT distance was independent of the following parameters: height, weight-for-age Z-score, FEV1, FVC, Shwachman score, colonisation with Pseudomonas aeruginosa. CONCLUSIONS The SWT is reproducible in paediatric patients with cystic fibrosis and provides assessment of respiratory performance that complements spirometric measures of lung function.

Abstract
Leachability of the plasticizer di(2-ethylhexyl) phthalate (DEHP) from administration sets into intravenous parenteral emulsions containing fat was investigated. DEHP is added to polyvinyl chloride (PVC) to impart flexibility. However, DEHP is a lipid-soluble suspected carcinogen that is hepatotoxic and teratogenic in rodents, and has been shown to leach from PVC products containing lipophilic mixtures. Consequently, total parenteral nutrition (TPN) mixtures containing fat emulsions should be stored in ethylvinyl acetate (EVA) bags rather than PVC packs. However, while TPN bags are made of EVA, they contain PVC-DEHP residues and the lines used between TPN bags and venous catheters are made of PVC-DEHP. The present study quantified the amount of DEHP leached from bags and tubing that could potentially contaminate patients during home TPN. Four types of emulsions containing fat were studied. Levels of DEHP in the bag and at the outlet tubing were measured by high-performance liquid chromatography (HPLC). This was measured during simulated TPN at different times after starting perfusion, 1 day after reconstitution of solutions in the bags, and 1 week later after storage at 4 degrees C. Detectable and stable amounts of DEHP were found to leach from bags (0.2 +/- 0.008 mg to 0.7 +/- 0.02 mg) and DEHP content increased in the outlet tubing (0.8 +/- 0.09 mg to 2 +/- 0.07 mg) during simulated infusions. The same phenomenon was observed after 1 week of storage at 4 degrees C. DEHP extraction by TPN depends on the lipid content of each TPN preparation and the flow rate. These results suggest that children treated with prolonged TPN are regularly exposed to significant amounts of DEHP.
