[Endoscopic therapy for pancreatitis in children].

Authors report on 3 cases of children treated by therapeutic endoscopic retrograde cholangiopancreatography for pancreatitis (ERCP). The first child presented with familial pancreatitis: he was treated by sphincterotomy and lithiasis extraction. The second child presented with pancreatitis secondary to pancreas divisum: she was treated by sphincterotomy and stunt of small caroncula. The third child presented with severe pancreatitis with pseudocyst: after drainage she was treated by sphincterotomy, Wirsung dilatation and lithiasis extraction. ERCP is a beneficial treatment and may be alternative to surgery in complicated pancreatitis.

[Breastfeeding and vegan diet].

Vegan diet in lactating women can induce vitamin B12 deficiency for their children with risk of an impaired neurological development. A 9.5-month-old girl presented with impaired growth and severe hypotonia. She had a macrocytic anemia secondary to vitamin B12 deficiency. MRI showed cerebral atrophy. She was exclusively breastfed. Her mother was also vitamin B12 deficient, secondary to a vegan diet. She had a macrocytic anemia when discharged from the maternity. Vegan diet is a totally inadequate regimen for pregnant and lactating women, especially for their children. Prevention is based on screening, information and vitamin supplementation.

Frequency and significance of granulomas in a cohort of incident cases of Crohn's disease.

BACKGROUND AND AIMS: Epithelioid granulomas is one of the best histological criterion for distinguishing Crohn's disease (CD) from other inflammatory bowel diseases. Few data are available on the time of occurrence of epithelioid granulomas, and the value of epithelioid granulomas in predicting outcome has been determined only in cohorts of prevalent CD cases. Our objective was to evaluate epithelioid granuloma occurrence in incident CD cases and to examine the associations between epithelioid granulomas and outcome. PATIENTS AND METHODS: We reviewed the histological reports of endoscopic and surgical specimens in a cohort of 188 consecutive incident CD cases seen in 1994 and 1995, and recorded the occurrence of epithelioid granulomas, isolated giant cells, and microgranulomas. Kaplan-Meier curves were plotted for time from CD diagnosis to immunosuppressive treatment or surgery, and associations between epithelioid granulomas and outcome were evaluated in a multivariate analysis. Follow up was at least five years. RESULTS: Granulomas were found in 69 (37%) patients, including 46 (25%) at presentation. Median time from CD diagnosis to epithelioid granuloma detection was 0.16 (0-63) months overall, and 9.59 (0.1-63) months in 23 patients who became epithelioid granuloma positive during follow up. Isolated giant cells were found in 6% of patients and microgranulomas in 12%. Epithelioid granuloma detection increased with the number of endoscopic sampling procedures; sampling site had no influence. By multivariate analysis, epithelioid granulomas were associated with surgical resection but not immunosuppressive therapy. CONCLUSIONS: Epithelioid granulomas may separate CD into two pathological subsets and may indicate aggressive disease.

[Diffusing capacity for carbon monoxide (T(LCO)) and oxygen saturation during exercise in patients with cystic fibrosis].

OBJECTIVES: To estimate the value of diffusing capacity for carbon monoxide (T(LCO)) in patients with cystic fibrosis and to evaluate its ability to predict arterial desaturation during exercise. METHOD: Fourty-four patients (9-30 years) with cystic fibrosis performed pulmonary function tests with measure of T(LCO) and a bicycle incremental exercise test. They represent a wide variation in disease severity: mean Shwachman score: 77.8 (range: 40-100), mean FEV1%: 72.8 (range: 17-131). This study investigated the relationship between T(LCO), lung volumes and exercise data. RESULTS: T(LCO) remained normal for a long time in patients with cystic fibrosis: 82% of them show a normal T(LCO) (mean value: 91.3% of predicted). T(LCO) was significantly correlated with FEV(1), residual volume, maximal work load and maximum oxygen uptake. A fall in arterial oxygen saturation was uncommon in our study (five patients) and not significantly correlated with T(LCO). CONCLUSIONS: T(LCO) is a good criter of severity of cystic fibrosis but remains unreliable to predict values above which physical activity is safe, without arterial desaturation. Exercise tests should be proposed in order to evaluate exercise adaptation of each patient and determine which factor limits maximal performance.

Comparing the clinical evolution of cystic fibrosis screened neonatally to that of cystic fibrosis diagnosed from clinical symptoms: a 10-year retrospective study in a French region (Brittany).

Until the year 2000, systematic cystic fibrosis (CF) neonatal screening was only performed in a few regions of France. The Brittany region began in 1989, but not the neighboring region of Loire-Atlantique. The present study compares the clinical evolution of both affected populations 10 years after screening was started. Although the 77 screened and 36 nonscreened children were followed in different CF centers, they were included in similar care protocols. The clinical characteristics at diagnosis and their evolution over a 10-year period of all the children affected with CF and born between January 1, 1989 and December 31, 1998, excluding those with meconium ileus, were compared. There were no significant differences in sex ratio, gestational age, anthropometric data at birth, frequency of deltaF508 homozygotes, proportion of pancreatic-insufficient patients, and mean age between the two populations. Age at diagnosis was lower in the screened group (38 days vs. 472 days, P < 10(-7)), as was the delay in supplementation with pancreatic enzymes (1.7 months vs.15.9 months, P < 10(-7)). The proportion of children who were hospitalized at least once was higher among the nonscreened than the screened patients (86% vs. 49%, P < 10(-4)). Z-scores for weight and height were significantly better in the screened population, not only in the first years of life, but also at 5 years old for height and 8 years old for weight. The Shwachman and Brasfield scores were higher among the screened children during the whole period of follow-up. No significant differences in colonization by Pseudomonas aeruginosa nor in lung function were found. Given the homogeneity in the characteristics and the follow-up of both populations, the benefits in terms of nutrition and clinical well-being of neonatal screening appear to be clear, thus confirming the advantages of its general implementation.

[Hemorrhagic colitis in exclusively breast-fed infants].

INTRODUCTION: Authors report clinical, biological and endoscopic data of six children aged less 3 months with bloody stools while they were exclusively breast-fed. RESULTS: Two girls and four boys aged 1 to 2 months presented with isolated but recurrent rectal bleeding. All were explored by fiberoptic rectosigmoidoscopy between 1 and 3,2 months. Macroscopic aspects were congestion (6 cases), petechial and ecchymotic (4 cases), with normal mucosal areas (5 cases). Histopathology showed eosinophilic infiltrates in all 5 children with rectal biopsy. Evolution was satisfactory after cow's milk protein exclusion in maternal diet for five children and after weaning in 1. All children were weaned with protein hydrolysate. Cow's milk protein were later introduced without adverse reactions at 6 to 23 months. CONCLUSION: Food allergy can be considered in proctocolitis including exclusive breast-fed children. Evolution after maternal diet is, as usual, simple.

[Factors associated with the choice of breast or bottle-feeding for hospitalized newborns].

UNLABELLED: This study was carried out in Rennes's maternity hospitals (France), to determine the breastfeeding rate for newborns hospitalized after birth, as well as the factors associated with the choice to breastfeed or not in these conditions. METHODS: Three hundred and twenty mothers delivered in Rennes Teaching Hospital, whose neonates were transferred in neonatal care unit, were questioned about their choice for neonate feeding. RESULTS: Three hundred and eight of the 320 mothers concerned by the study answered our interview. Fifty one percent of them chose to breast feed, which is near the breastfeeding rate of the general population of Rennes' maternity hospitals (52%). A high sociocultural level, a mother previously breastfed herself, and a previous breast feeding (RR = 5.2; P < 10(-8)) were associated with the choice of breastfeeding. Factors concerning the information of the mothers were also associated with the choice of breastfeeding information during the preparation to birth sessions (RR = 1.7; P < 10(-5)), individual information on the breastfeeding of an ill newborn (RR = 1.5; P < 0.01), and the simple advice to breastfeed given by a health care professional (RR = 2; P < 10(-8)). Of the four qualities named, the more breast-milk qualities a mother knew, the higher breastfeeding rate was (10% for none, 27% for one, 54% for two, and 76% for three or four). Concerning the postnatal factors, gestational age below 31 weeks multiplied breast feeding by 1.5 (P < 0.05), and an early contact mother-child (first day) by 1.3 (P < 0.05). CONCLUSION: This study pointed out the populations at risk of no breastfeeding. Informations on the properties of breastfeeding given to mothers by health care professionals may influence them in their choice of breast feeding or not their ill newborn.

[Incidence of symptomatic celiac disease in French children].

OBJECTIVE: The study was carried out by the GFHGNP to determine the annual incidence of symptomatic celiac disease in children. PATIENTS AND METHODS: The diagnostic criteria were: symptomatic patients diagnosed under 15 years of age during 1996, villous atrophy and positivity of antigliadin and/or other antibodies. Cases were collected from referral centers, general hospital pediatric departments and private pediatricians with endoscopic practice. RESULTS: The study involved roughly half of the French pediatric population in 41 out of the 95 French districts. In all, 124 patients were collected: 76 girls and 48 boys. By geographical areas, in 30 districts where collection of data was complete which counted 186,285 births, the yearly incidence varied from 1/1731 births to 1/3110. (0.57@1000 to 0.32@1000). On the whole there were 77 cases i.e. an annual incidence of 1/2419 or 0.41@1000 (confidence interval 95%: 0.32 to 0.50@1000). Lower incidences were observed in the district of Paris: 1/4865 (0.21@1000) and Lyon: 1/3310 (0.27@1000). Those lower incidences could be explained by the difficulties of collecting the data in the biggest urban areas. The first signs occurred before one year of age in 73% of the cases, during the second year of life in 20.5% and after 3 in only 6.5%. The diagnosis was made before 2 years of age in 77% of the cases and after 3 in only 13%. In order of frequency symptoms were: failure to thrive (80%), diarrhea (59%), anorexia (59%), abdominal distension (57%), weight under 2 standard deviations (43%), short stature (43%). CONCLUSION: Compared with previous studies in two French districts between 1975 and 1990, the annual incidence of symptomatic celiac disease in children appears to be on the rise. The usual clinical signs continue to be observed.

[Anemia and limping in a vegetarian adolescent].

UNLABELLED: A vegan diet in the child and adolescent can induce severe bone sequelae by rickets and osteomalacia and megaloblastic anemia by cobalamin deficiency. CASE REPORT: A 15-year-old adolescent was hospitalized because of lameness and pallor. The lameness was explained by femoral epiphysiolysis caused by rickets with severe hypocalcemia. The pallor, jaundice and splenomegalia were due to cobalamin-deficiency megaloblastic anemia. A prolonged supplemental diet with calcium, vitamins D and B12 as well as orthopedic treatment stabilized the bone lesions. The megaloblastic anemia was cured by parenteral cobalamin. The adolescent and his brother were victims of a diet imposed by a cult and a lack of care due to their parents refusing that a vegan diet was the cause of the deficient pathology. Penal proceedings led to the incarceration of the parents and to the placement of the children. COMMENTS: Deficiencies in calcium and vitamins D and B12 may be severe in a child's development with a vegan diet. This case report reveals the social and legal problems of an inappropriate diet in infancy imposed by parents who are followers of a fundamentalist church. Beyond the management of children in cults, health professionals have to prevent, screen and supplement the deficient diet.

[Incidence of inflammatory bowel disease in children in Brittany (1994-1997). Breton association of study and research on digestive system diseases (Abermad)].

BACKGROUND: The aim of this work was to determine in Brittany the incidence and main clinical pattern of inflammatory bowel disease (IBD) occurring during childhood. These data are compared to the previous epidemiologic data available from the Northern France registry or around the world. METHODS: Private and public Brittany gastroenterologists (2,836,418 inhabitants including 618,049 children under 17 years of age) referred all patients consulting for inflammatory bowel disease from January 1994 to December 1997. An interviewer-practitioner completed at the gastroenterologist's office a standard questionnaire for each patient. Each case was independently reviewed by four experts in a blind manner and made a final diagnosis of Crohn's disease (CD), ulcerative colitis (UC), or ulcerative proctitis and acute colitis (onset of symptoms < 6 weeks) or unclassified chronic colitis. RESULTS: Among 1,309 cases recorded, 88 were under 17 years of age (6.7%): 43 (49%) had CD (including three possible cases), 14 (16%) had UC (including three proctitis), 24 (27%) acute colitis and 7 (8%) unclassified chronic colitis. The crude mean annual incidence (per 100,000 children) based on definite and probable cases only was 2.5 for IBD, 1.6 for CD and 0.57 for UC, without variation between 1994 and 1997. The male/female ratio was 2.3 for CD and 1.3 for UC. The mean time between onset of disease and diagnosis was equal to 7.2 and 8.6 months for CD and UC respectively (median: 3 and 5 months). A familial history of IBD was present in 5 cases (8%). In CD, the small and large bowel were involved in 58% of patients, whereas an isolated involvement of small or large bowel occurred in 15% and 23% of cases. Among the 14 UC, there were three proctitis and four pancolitis. Among 43 CD, a granuloma was present in 48% of cases. CONCLUSIONS: In Brittany the incidence of CD and UC in childhood was similar to the published data from Northern France. Clinical presentation and symptoms were not different. However, the rate of acute colitis was higher and the accurate incidence of IBD could be underestimated, requiring a follow-up to classify these cases.

Effect of glucose to fat ratio on energy substrate disposal in children with cystic fibrosis fed enterally.

High fat containing diets lower VCO(2)in patients with impaired pulmonary function fed at a high level of energy intake. We tested the effect of a high fat enteral nutrition on VCO(2)and substrate oxidation in cystic fibrosis patients fed enterally 130% RDA. VCO(2)and substrate oxidation were studied in a group of eight 6-19 year old patients while receiving for 1 month and in a random order isocaloric (1000 kcal/m(2)), isonitrogenous enteral diet with a normal fat and a high fat content (40% and 67% of non-protein energy intake). Substrate oxidation and net balance were estimated using indirect calorimetry at the end of each study period. Overnight high fat enteral infusion resulted in no significant change in VCO(2)and VO(2)but lowered RQ (0.84 +/- 0.01 vs 0.88 +/- 0.01, P= 0.02) and non-protein RQ (0.83 +/- 0.01 vs 0.88 +/- 0.01). In spite of a higher glucose oxidation rate (8.1 +/- 0.5 vs 6.3 +/- 0.5 g. h(-1), P= 0.04), glucose net balance was significantly higher during normal fat formula administration (+2.5 +/- 0.8 v -0.3 7plusmn; 0.7 g/h, P< 0.05). The present study failed to show any benefit of a high fat diet on VCO(2)in non oxygenodependant cystic fibrosis children and adolescents fed slightly above RAD. Normal fat enteral formula led to higher glycogen repletion.

Chronic intestinal pseudoobstruction syndrome: clinical analysis, outcome, and prognosis in 105 children. French-Speaking Group of Pediatric Gastroenterology.

Our aim was to collect a large number of cases to characterize clinical presentation, outcome, and prognosis of chronic intestinal pseusoobstruction in children. We conducted a retrospective multicenter study that included children treated for chronic intestinal pseusoobstruction defined as recurrent episodes of intestinal obstruction with no mechanical obstruction, excluding Hirschsprung's disease. In all, 105 children, 57 boys and 48 girls, were studied, including five familial forms. Prenatal diagnosis was made in 18 patients. Eighty patients were less than 12 months old at onset; the disease began at birth for 37 patients. The most frequent signs were abdominal distension, vomiting, and constipation. Megacystis was noted in myopathies (7 cases), neuropathies (10 cases) and unclassified forms (13 cases). For all but three cases (two patients with CMV infection, one with Munchhausen-by-proxy syndrome), the associated diseases and disorders could not account for chronic intestinal pseusoobstruction as a secondary disorder. At least one full-thickness biopsy from the digestive tract was studied for 99 patients. The diagnosis recorded was visceral neuropathy in 58 cases, visceral myopathy in 17 cases, and uncertain or normal biopsy results in 24 cases. Seventy-eight children were fed intravenously, and only 18 were able to be fed orally throughout their illness. Seventy-one patients underwent surgery during their illness, and 217 surgical procedures, a mean of 3 per patient, were performed. Ostomy was the most performed procedure. Follow-up continued in 89 patients for 3 months to 16 years (mean 85 months). Forty-two patients were still fed by parenteral (39 patients) or enteral nutrition (3 patients) at the time of the study. Eleven patients died between the age of 1 month and 14 years 7 months.
