[Acquired non hypertrophic pyloric stenosis in children].

UNLABELLED: Pediatric non hypertrophic pyloric stenosis (NHPS) are uncommon. Their causes and treatments are debated. MATERIAL AND METHOD: Retrospective review of all cases of NHPS from 3 pediatric surgery services during the period 1984-2002. RESULTS: Six children, aged 17 months to 15 years, underwent surgery for NHPS. Clinical symptoms, food vomiting and loss of weight, were present for several weeks before the diagnosis of NHPS was made. The diagnosis was peptic stenosis in 3 cases and has not been established in 3 cases. Search for Helicobacter pylori was negative in all cases. Failure of specific medical treatment and endoscopic dilatations led to pyloric resection in 3 cases and pyloroplasty in 3 cases. Post operative course was uneventful with normal oral feeding and normalisation of weight status. Histologic data were aspecific. No recurrence was observed. DISCUSSION: We discuss the origin of the pyloric stenosis, regarding clinical, operative and pathological data: were the stenosis the cause or consequence of peptic ulcer? Peptic disease is always advocated, but difficult to prove and may be excessively incriminated. Late symptomatic congenital and acquired idiopathic pyloric stenosis should be recalled. In all cases of proved pyloric stenosis, after failure of medical and endoscopic treatment, a simple surgical procedure (pyloroplasty) associated with medical treatment seems to be effective. CONCLUSION: The diagnosis of NHPS should be suspected in a child with food vomiting and loss of weight if his age is not concordant with hypertrophic pyloric stenosis. Upper gastro-intestinal series and endoscopy are diagnostic. The precise cause of the stenosis is more difficult to asses. When the medical treatment fails, a pyloroplasty is usually curative.

[Pathologic childhood aerophagia].

UNLABELLED: "Air swallowing" described as being part of functional gastrointestinal disorders in "Rome criteria" in 1999 is often misdiagnosed, particularly in non-mentally deficient children. AIMS: To recognize "air swallowing" child and to describe any progress according to the treatment. POPULATION AND METHODS: This retrospective study reports 13 cases of children without mental deficiency or neuromuscular disease. Clinical elements and precise histories are detailed and we have contacted consulting doctors or families for news. RESULTS: Ten boys and 3 girls, from 2,5 years to 10 years old, were referred for long lasting pain or abdominal distension. Numerous laboratory investigations were always normal. Diagnosis relied upon the observation of air swallowing and X-Rays views of gastric distension. Air swallowing was observed 7 times, 9 children had twitches and 3 language troubles. In 10 cases, X-rays showed gastric and colic distension. Three children have Chilaïditi syndrome. Favourable results followed in 12 cases after an average of 28 months of treatment. One case was lost for follow-up. Treatment was long, often disappointing and required the intervention of a psychiatrist, a paediatrician and (temporarily) a speech therapist. CONCLUSION: Pathological childhood aerophagia is often underdiagnosed and deserves to be better known by paediatricians, psychiatrists and surgeons. A late diagnosis leads to many negative results and causes anxiety. An early diagnosis should lead to a multidisciplinary care.

[Recurrent Castleman's disease of the neck occurring in an infant].

INTRODUCTION: Castleman's disease is a lympho-proliferative disease of unknown cause. This rare disease, usually localized, is benign and develops in the young adult. The predominant localization is mediastinal. OBSERVATION: A 15 month-old infant was referred for a left latero-cervical mass that had developed since the age of 3 months. Other than this, the clinical examination was normal. Sonography, x-ray and tomodensitometry confirmed the unique nature of the lesion and the absence of loco-regional invasion. Histology following surgical exeresis found a nodule with multiple pseudo-follicular structures. These mitosis-rich structures were arranged concentrically around a vessel and were bordered by small lymphocytes forming a crown. This histological aspect corresponded to Castleman's disease in its vascular hyaline form. Local recurrence was reported twice, 2 and 8 years later and was treated each time with surgical exeresis. Histological examination was always similar to the first. DISCUSSION: Castleman's disease has rarely been reported in infants. The cervical location, at whatever age, is far rarer than the mediastinal form. Supplementary examinations are not always of interest and basically provide information on the isolated or multicentric nature. Surgical exeresis was justified because of the diagnostic doubts and the risk of compression. Diagnosis is based on anatomopathology. Relapses have rarely been described in the literature and raise the question of the potential malignant transformation after several relapses.

[Acute gastro-enteritis in children in France: estimates of disease burden through national hospital discharge data].

OBJECTIVES: To estimate the burden of hospitalized infectious gastroenteritis of children younger than 5 years of age and associated costs. METHODS: We analyzed 1997 hospital discharges with a primary diagnosis of gastroenteritis or a secondary diagnosis of gastroenteritis with gastroenteritis symptoms or complications as primary diagnosis and compared the deaths with those of the national mortality data. RESULTS: Gastroenteritis was associated with 51,125 hospitalizations which accounted for 11.4% of hospitalization discharges for this age group and an annual rate of 1,385 per 100,000 children <5-year-old. Most gastroenteritis (56%) were registered as "probably infectious", 36% as "viral" (43% of which were coded "rotavirus") and 8% as "bacterial" (of which 60% were coded "Salmonella"). The seasonal peak was winter for rotaviral, viral and "probably infectious" gastroenteritis, summer for those related to salmonellosis. Incidence increased inversely with age: 3606/100,000 infants <1-year-old, 257/100,000 4-year-old children. Complications (especially dehydration) were observed in 21% of viral gastroenteritis and 17% of bacterial gastroenteritis. At least, 14 deaths were found in both hospital discharge and mortality data. The mean duration of stay (3.2 days) was significantly higher in infants <1-year-old, viral etiology, association with complications or bronchiolitis. The costs of hospitalization could be estimated to 62 million Euros. DISCUSSION: Our results are similar to those obtained in other developed countries. Despite variations in encoding the discharge reports, data has proven to be effective to describe national trends for this health event. Our study indicates that the public health burden and economic impact of prevention and control measures can be monitored through hospital discharge surveillance.

[Analysis of an apparent cluster of Crohn's disease cases in Indre-et-Loire, France (1990-1999)].

BACKGROUND: Four cases of Crohn disease (CD) were diagnosed between 1990 and 1997 in children living in the same area in the Indre-et-Loire district (county A). The local population raised the hypothesis that an environmental source could be responsible for these cases. An investigation was carried out to assess the excess of cases and to identify their possible determinants. METHODS: A case was defined as any new case of CD (European definition) that occurred between 1989 and 1998 in county A or in the adjacent county of the Vienne district. Case finding was done by contacting all hospital services, pediatricians and gastro-enterologists in the 2 districts. A Standardized Incidence Rate (SIR) was calculated for sex and age in adults and children using data from the Inflammatory Bowel Registry of northern France. Statistical significance was assessed by a test taking into account small samples. A descriptive study was carried out among pediatric cases. RESULTS: Four pediatric cases and four adults were identified, all from county A. The SIR in adults was 0,45 (95% Confidence Interval [95% CI: 0.12-1.15). In children, the global SIR was 8,51 (95% CI: 2.29-21.79) and 19,05 (95% CI: 5.12-48.70) in county A. The descriptive study did not identify any exposure leading to a possible hypothesis concerning the origin of the cases. CONCLUSION: This study has shown that the incidence of CD among children of the area was greater than observed in France and has permitted to establish a close relationship with the affected families, to implement a social approach to the problem and to limit rumors. It illustrates the interest of a systematic stepwise approach, which takes into consideration the anxiety of the local community. Cluster investigation should be integrated as part of the public health agencies activities. However, in most cases, despite an excess risk, results do not allow to conclude in terms of etiology.

[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.

Efficacy and tolerability of racecadotril in acute diarrhea in children.

BACKGROUND & AIMS: Oral rehydration therapy is the only treatment recommended by the World Health Organization in acute diarrhea in children. Antisecretory drugs available could not be used because of their side effects, except for racecadotril, which is efficient in acute diarrhea in adults. METHODS: The efficacy and tolerability of racecadotril (1.5 mg/kg administered orally 3 times daily) as adjuvant therapy to oral rehydration were compared with those of placebo in 172 infants aged 3 months to 4 years (mean age, 12.8 months) who had acute diarrhea. The treatment groups were comparable in terms of age, duration of diarrhea, number of stools, and causative microorganism at inclusion. RESULTS: During the first 48 hours of treatment, patients receiving racecadotril had a significantly lower stool output (grams per hour) than those receiving placebo. The 95% confidence interval was 43%-88% for the full data set (n = 166; P = 0.009) and 33%-75% for the per-protocol population (n = 116; P = 0.001). There was no difference between treatments depending on rotavirus status. Significant differences between treatment groups were also found after 24 hours of treatment: full data set (n = 167; P = 0.026) and per-protocol population (n = 121; P = 0.015). Tolerability was good in both groups of patients. CONCLUSIONS: This study demonstrates the efficacy (up to 50% reduction in stool output) and tolerability of racecadotril as adjuvant therapy to oral rehydration solution in the treatment of severe diarrhea in infants and children.

Omeprazole combined with amoxicillin and clarithromycin in the eradication of Helicobacter pylori in children with gastritis: A prospective randomized double-blind trial.

OBJECTIVES: The aim of this multicenter prospective, randomized, double-blind study was to assess the efficacy of the combination of omeprazole, amoxicillin, and clarithromycin (OAC) for the treatment of Helicobacter pylori gastritis in children. STUDY DESIGN: Seventy-three children with dyspeptic symptoms were included in the trial (mean age 10.8 years; range, 3.3 to 15.4). Patients were randomized to receive OAC or amoxicillin and clarithromycin (AC) for 7 days. H pylori status was assessed before and 4 weeks after eradication treatment, by use of the carbon 13-labeled urea breath test. RESULTS: In intent-to-treat analysis (n = 63), eradication rates were 74.2% (95% CI, 58.7 to 89.6) in the OAC group and 9.4% (95% CI, 0 to 19.5) in the AC group. In per-protocol analysis (n = 53), the eradication rate increased to 80% (95% CI, 64.3 to 95.7), remaining significantly higher than in AC group (10.7%; 95% CI, 0 to 22.2). Resistance of strains to clarithromycin was rare (3/39 = 7.7%) and was not associated with failure of treatment. Adverse events were reported in 24.6% of patients and remained mild. CONCLUSION: This study shows that 1-week OAC triple therapy results in successful eradication of H pylori in 75% of children with gastritis.

Apolipoprotein B Arg3500Gln mutation prevalence in children with hypercholesterolemia: a French multicenter study.

BACKGROUND: Familial defective apolipoprotein B-100, a dominantly inherited form of hypercholesterolemia caused by a single Arg3500Gln mutation, is silent in childhood but may confer a high risk of cardiovascular disease in adulthood. The objective was to determine the prevalence of familial defective apolipoprotein B-100 in hypercholesterolemic French children and to provide a basis for targeting screening efforts in this population. METHODS: One hundred ninety children attending 13 pediatric clinics distributed throughout France were included based on the presence of type IIa hypercholesterolemia with a plasma low-density lipoprotein-cholesterol level of more than 130 mg/dL. The Arg3500Gln mutation was detected in dried blood spots using a polymerase chain reaction assay combined with enzymatic restriction. RESULTS: Three hyperlipidemia phenotypes were found: monogenic dominant pure hypercholesterolemia (n = 117), polygenic hypercholesterolemia (n = 43), and combined hyperlipidemia (n = 11). Three unrelated children were heterozygous for the Arg3500Gln mutation; all three had monogenic dominant pure hypercholesterolemia (3/94 families; 3.2%), yielding a prevalence of 1.83% (3/164) in hypercholesterolemic children, which is similar to prevalences reported in European adults. CONCLUSIONS: The familial defective apolipoprotein B-100 mutation was common (1/31) in children with a phenotype of familial hypercholesterolemia, supporting screening in this population with the goal of preventing premature cardiovascular events.

[Fatal toxic respiratory epitheliolysis. Subacute tracheo-bronchial desquamation in Stevens-Johnson syndrome].

Acute bronchial mucosal sloughing related to Toxic Epidermal Necrolysis (Lyell syndrome) is widely reported in literature. On the contrary severe respiratory involvement is rare in post-infectious or toxic Epitheliolysis (Stevens-Johnson syndrome). There is no well-known predictive sign of bronchial epithelium involvement. An 18-year-old patient was admitted for Stevens-Johnson syndrome related to sulfasalazine (salazosulfapyridine). There were no respiratory signs. An acute respiratory failure occurred 36 hours after from admission due to an obstructive and desquamative necrosis of the tracheobronchial epithelium. We purpose that a fiberoptic laryngoscopy should be performed even in non-dyspneic patients suffering from Stevens-Johnson syndrome if hypersecretion is present. Fiberoptic bronchoscopy can be helpful in these cases.

Jeune syndrome and liver disease: report of three cases treated with ursodeoxycholic acid.

Three children with Jeune syndrome (asphyxiating thoracic dystrophy) had clinical and laboratory evidence of liver disease. In two patients the disease evolved to biliary cirrhosis, whereas in the third it was recognized when extensive fibrosis was developing. In the three patients, treatment with ursodeoxycholic acid appeared to control the progression of the hepatic dysfunction.

[Children of foreign origin adopted in France. Analysis of 68 cases during l2 years at the University Hospital Center of Tours].

BACKGROUND: The number of children of foreign origin adopted in France has increased in the past 15 years. The aim of this study was to analyse distinctive features and medical problems associated with international adoption. PATIENTS AND METHODS: The files of 68 foreign-origin adopted children who attended or were admitted to the Medical and Nutrition Unit of the Pediatric Hospital in Tours between January 1st 1986 and December 31st 1997, were studied retrospectively. Various parameters were analysed: age at first consultation, age at adoption, country of origin and health problems, especially nutritional status, infectious diseases, growth and development. RESULTS: In the majority of cases, children were adopted before 12 months of age (61.2%), particularly before six months of age (49.3%). The children came mainly from Africa and countries in the Indian Ocean (48.5%), and from Southeastern Asia (33.9%). Malnutrition was frequent in children from Africa. Twenty-one children (30.9%) presented with severe malnutrition characterized by weight less than the mean-2SD for height and required hospitalization. No children had congenital hypothyroidism, hyperphenylalaninemia, nor were HIV positive. Some patients had infectious diseases: 11 Hepatitis B, four congenital syphilis and six tuberculosis, with favorable outcomes after treatment. The other most frequent diseases were acute diarrhea, chronic diarrhea, intestinal parasites, and scabies, varying according to countries. Three girls adopted from southern Asia developed precocious puberty. Growth and psychomotor development were satisfactory overall, but abnormalities were observed in 15 children (22.1%), which is higher than in the general population. CONCLUSION: The expansion of international adoption with distinctive diseases proves the importance of a checkup as soon as possible after the arrival of these children in France. This checkup has to include nutritional and general evaluation and supplementary tests, especially for specific serology and vaccination status. Following this, it would be possible to propose a suitable follow-up to the adoptive parents.

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.

Blood lipid concentrations of docosahexaenoic and arachidonic acids at birth determine their relative postnatal changes in term infants fed breast milk or formula.

BACKGROUND: Factors other than dietary fatty acids could be involved in the variability observed in blood docosahexaenoate (22:6n-3) and arachidonate (20:4n-6) status in formula-fed infants. OBJECTIVE: We considered the 22:6n-3 and 20:4n-6 status at birth to be one of these factors and studied its influence on postnatal changes in term infants fed 4 different diets. DESIGN: The blood phospholipid composition was determined at birth and on day 42 of feeding in 83 term infants fed breast milk, nonsupplemented formula, or 2 different 22:6n-3-supplemented formulas. Relations between 22:6n-3 and 20:4n-6 status at birth and their relative postnatal changes, calculated by the difference between status at the end of the feeding period (6 wk of age) and at birth, were assessed. RESULTS: Postnatal changes in the plasma and erythrocyte phospholipids 22:6n-3 and 20:4n-6 were negatively related to their respective concentrations at birth (P < 0.01) and the slopes of the regression lines were not significantly affected by the type of milk ingested. Adjusted mean values for phospholipid 22:6n-3 in nonsupplemented-formula-fed infants and for 20:4n-6 in formula-fed infants decreased significantly more than they did in the other infant groups (P < 0.02). The status at birth and the type of milk ingested explained 33-64% and 7-47%, respectively, of the variability in postnatal changes. CONCLUSIONS: The status of 22:6n-3 and 20:4n-6 at birth in term infants is one of the major determinants of postnatal changes in these fatty acids. This finding indicates that research is required to characterize environmental, genetic, or both factors, which, in addition to maternal diet, could influence fatty acid status at birth.
