Oral manifestations of celiac disease in French children.

Celiac disease (CD) is an immune-mediated systemic disorder caused by ingestion of the gluten found in wheat, rye, and barley. The currently estimated prevalence in children is about 1%. CD is a chronic enteropathy with gastrointestinal manifestations including diarrhea, abdominal distension and weight loss, but extra-intestinal features are increasingly being reported. Dental and oral manifestations such as dental enamel defects (ED), delay in dental eruption, and recurrent aphthous stomatitis (RAS) are well-recognized manifestations of CD. The aim of this study was to compare the frequency of oral manifestations (ED, RAS and delay in dental eruption) on deciduous and permanent teeth between children with CD and a control population. An oral examination was performed on 28 CD children and 59 control children. All children were younger than 12 years old and had deciduous or mixed dentition. CD children had significantly more ED and RAS than the control group (67.9% vs. 33.9% P=0.004 and 50.0% vs. 21.8% P=0.011, respectively). No delay in dental eruption was observed in CD children. ED were mainly grade I and II of Aine's classification (color defects and slight structural defects). ED were more often seen on CD children's deciduous teeth than on permanent teeth (57.1% and 13.6%, respectively; P<0.001). The main teeth affected by ED are the second molar and canines of the deciduous teeth, and the first molar, central incisor, and lateral incisors of the permanent teeth. RAS and ED that were symmetrical in all quadrants and occurred firstly in teeth that mineralize during the first year of life both seem to be signs of CD. Thus, more information for dentists and pediatricians on these oral manifestations should help improve detection of CD.

Negative influence of maternal smoking during pregnancy on infant outcomes.

BACKGROUND: According to the INPES 2014 health barometer, the prevalence of smoking in pregnant women in France is the highest in Europe : 17.8% of expectant mothers who smoke continue to do so during pregnancy. Several epidemiological studies have confirmed multiple risks for tobacco-exposed infants (low birth weight; digestive, respiratory, neurological, and psychological disorders; obesity; type 1 diabetes). PURPOSE: This study compared a cohort of infants exposed to tobacco in utero (T+) with those unexposed (T-). Birth weight, diet, presence of colic (ROME III criteria) and regurgitations (Vandenplas scale) were specifically analyzed. METHODS: This observational, cross-sectional, and multicenter survey was conducted in France by pediatricians and general practitioners from September 2016 to February 2017. Infants with a chronic pathology and those with parents under 18 years of age were excluded. The data were collected by the physician and by the mother through a self-administered questionnaire. RESULTS: A total of 452 physicians recruited 759 T+ and 741 T- infants in the study. The mean birth weight of T+ infants was significantly lower (3.1±0.5 kg [WHO z-score -0.476±1.081]) than that of T- infants (3.3±0.5 kg [0.033±0.965]; P<0.001). At the time of leaving the maternity facility, 47.7% of T+ infants were breastfed by their mother compared with 70.1% of T- infants. The median reported duration of breastfeeding was 1 month vs. 2 months for T+ and T- infants, respectively. Colic was significantly more common in T+ than in T- infants: 25.6% vs. 12.3% according to the ROME III criteria, and 45.7% vs. 29.7% according to the doctor's opinion (P<0.001 for both). In the T+ group, cases of regurgitation (63.6% vs. 56.5%; P=0.005), respiratory disorder (6.3% vs. 2.4%, P<0.001), and bronchiolitis (6.5% vs. 3.0%; P=0.001) were also more frequent. CONCLUSION: This study confirms that maternal smoking during pregnancy is associated with health risks; exposed infants had significantly more digestive/respiratory symptoms and lower birth weight than unexposed infants. Preventive and educational actions need to be further strengthened in the face of this public health problem.

Clinical applicability of diagnostic biomarkers in early-onset cognitive impairment.

BACKGROUND AND PURPOSE: Several diagnostic biomarkers are currently available for clinical use in early-onset cognitive impairment. The decision on which biomarker is used in each patient depends on several factors such as its predictive value or tolerability. METHODS: There were a total of 40 subjects with early-onset cognitive complaints (<65 years of age): 26 with Alzheimer's disease (AD), five with frontotemporal dementia and nine with diagnostic suspicion of non-neurodegenerative disorder. Clinical and neuropsychological evaluation, lumbar puncture for cerebrospinal fluid (CSF) AD core biochemical marker determination, medial temporal atrophy evaluation on magnetic resonance imaging, amyloid-positron emission tomography (PET) and 18 F-fluorodeoxyglucose-PET were performed. Neurologists provided pre- and post-biomarker diagnosis, together with diagnostic confidence and clinical/therapeutic management. Patients scored the tolerability of each procedure. RESULTS: Cerebrospinal fluid biomarkers and amyloid-PET increased diagnostic confidence in AD (77.4%-86.2% after CSF, 92.4% after amyloid-PET, P < 0.01) and non-neurodegenerative conditions (53.6%-75% after CSF, 95% after amyloid-PET, P < 0.05). Biomarker results led to diagnostic (32.5%) and treatment (32.5%) changes. All tests were well tolerated. CONCLUSIONS: Biomarker procedures are well tolerated and have an important diagnostic/therapeutic impact on early-onset cognitive impairment.

[Early restrictive feeding disorders: Quantitative assessment of parent/infant feeding interactions]. / Troubles du comportement alimentaire restrictif du nourrisson et du jeune enfant : évaluation quantitative des interactions parent/nourrisson pendant le repas.

INTRODUCTION: Interest in the study of early feeding disorders (FD) has steadily increased during recent decades. During this period, research described the importance of the transactional relationships and the complex interplay between caregiver and child over time. On the basis of the previous studies, our study tried to explore the associations between the characteristics of the parents and the temperamental characteristics of the infants with early FD. GOALS: A first aim of the present study was to show if parental perception of child temperament (including ability for arousal self-regulation) and parental characteristics (emotional and eating attitudes) are associated with early FD. A second aim was to identify emotional/behavioral difficulties in children with early FD by comparing children with a normal development and children with a diagnosed FD, and to investigate whether there are any correlations between parental emotional and feeding characteristics and a child's eating and emotional-behavioral development. A final aim was to explore if feeding conflict is bound to both infant ability for arousal self-regulatation and caregiver emotional status during meals. METHOD: Participants: 58 clinical dyads (children aged 1-36 months) and 60 in the control group participated in the study. The sample of 58 infants and young children and their parents was recruited in a pediatric hospital. They were compared to healthy children recruited in several nurseries. PROCEDURE: all parent-child pairs in the clinical sample were observed in a 20-minute video-recording during a meal using the procedure of the Chatoor Feeding Scale. After the videotaping, parents completed a battery of self-report questionnaires assessing their child's and their own psychological symptom status. MEASURES: Child's malnutrition assessment was based on the Waterlow criteria. The Child Behavior Checklist (CBCL 1½-5) was used to assess a child's emotional/behavioral functioning. The Infant Behavior Questionnaire-Revised (IBQ-R), a widely used parent-report measure of infant temperament, was used to identify the structure of infant temperament. The Eating Attitude Test-40, a self-report symptom inventory, was used to identify concerns with eating and weight in the adult population. The Chatoor Feeding Scale was used to assess mother-child feeding interactions during a meal based on the analysis of the videotaped feeding session. RESULTS: Analyses revealed that children with FD did not have a difficult temperament, especially no disability for arousal of self-regulatation, but their emotional-behavioral functioning is characterized by internalizing problems. Analyses of the EAT-40 showed that mothers of the children diagnosed with FD had significantly higher scores than mothers of the control sample; it means these mothers showed more dysfunctional eating attitudes. In addition, meals were characterized by negative effects in parents in the clinical group. When compared to the control sample, the feeding interactions between children with FD and their parents were characterized by low dyadic reciprocity, high maternal non-contingency, great interactional conflict and struggles with food. However, no significant correlation emerged either between the severity of malnutrition in infants or the conflict during feeding. CONCLUSION: Our study confirms the relations established in previous research. Finally, future longitudinal studies are needed to further clarify and investigate others factors that may be involved in early feeding disorders.

La narcolepsia «va a la escuela» / Narcolepsy «goes to school»

Introducción: La narcolepsia es una de las causas más comunes de somnolencia crónica. A pesar de ello, el tiempo entre el inicio de los síntomas y el diagnóstico oscila entre 5 y 15 años, y puede ser un trastorno infradiagnosticado en muchos pacientes. La clínica suele empezar a partir de los 10 años de edad, pero es difícil identificarla si aparece a edades inferiores. Presentamos el caso clínico de un niño con diagnóstico de narcolepsia con sólo 5 años de edad. Caso clínico: Niño de 5 años de edad, con excesiva somnolencia diurna acompañada de episodios de atonía ocasional de 1 mes de evolución. Se planteó un amplio diagnóstico diferencial y se solicitaron pruebas complementarias para su estudio. Ante la sospecha de narcolepsia, se realizó una videopolisomnografía nocturna, seguida de un test de latencias múltiples. En ambas pruebas se obtuvieron resultados compatibles con el diagnóstico de narcolepsia. Se practicó una punción lumbar, en la que se analizaron los valores de hipocretina en el líquido cefalorraquídeo, que resultaron indetectables. Junto con estos resultados, se solicitó la determinación de HLA DQ en sangre, con lo que se concluyó que el paciente era homocigoto por DQ6.2, indicativo de susceptibilidad a sufrir narcolepsia. Ante estos hallazgos se inició tratamiento. Conclusiones: Se presenta un caso de narcolepsia, peculiar por la edad de su inicio, con la finalidad de difundir esta entidad en el medio pediátrico y su forma de presentación, que difiere de la de los adultos. Su diagnóstico precoz permite un tratamiento eficaz y mejorar la calidad de vida de estos pacientes (AU)

Introduction: Narcolepsy is a chronic debilitating sleep disorder. Nevertheless, the time between the symptoms and diagnosis ranges from 5 to 15 years, and may be an underdiagnosed disorder in many patients. Disease onset occurs mainly around 10 years, but is difficult to identify if it appears at lower ages. We present the clinical case of a child diagnosed with narcolepsy at only 5 years of age. Case report: A 5-year-old child, with excessive daytime sleepiness and occasional episodes of sudden loss of muscle tone of 1 month evolution. A large differential diagnosis was proposed and complementary tests were performed for its study. On suspicion of narcolepsy, a nocturnal videopolisomnography was done, followed by a multiple latency test. In both tests, the results were consistent with the diagnosis of narcolepsy. The values of hypocretin in the cerebrospinal fluid were undetectable. The HLA DQ in blood, concluded that the patient was homozygous for DQ6.2, indicative of susceptibility to narcolepsy. Conclusions: A case of narcolepsy is presented, due to the early age of onset, in order to spread this entity in children, which differs from adults. Its early diagnosis allows improve the quality of life of these patients (AU)

[Causes of iron deficiency in children]. / Causes des déficits en fer chez l'enfant.

Iron deficiency and iron deficiency anemia are common conditions worldwide affecting especially children. In developing countries, iron deficiency is caused by poor iron intake and parasitic infection. Poor iron intake linked to inadequate diets, low iron intestinal absorption, chronic blood losses and increased requirements are common causes in high-income countries.

[Feeding disorders in infants and toddlers: At-risk situations and predisposing factors]. / Troubles du comportement alimentaire restrictifs du nourrisson et du jeune enfant : situations à risque et facteurs favorisants.

Feeding disorders and food refusal can be found in 25% of infants, with a minority of them having an organic explanation. Failure to thrive and/or severe malnutrition are found in 3-5% of infants in this population. The objective of this study was to analyze the risk factors of feeding disorders in infants and children less than 3 years of age. This study was conducted from January 2011 to December 2014 and included 103 children, 57 with feeding and/or eating disorders and 46 healthy children considered to be normal eaters. Parents participated in a structured interview and completed a data sheet to record the mode of delivery, neonatal status, medical history, milk feeding, and medical treatment. Statistical analysis indicated that cesarean delivery, prematurity, neonatal diseases, history of eating disorders in the family, consumption of protein hydrolysates, and treatment with proton pump inhibitors were highly significant risk factors in children with eating disorders. In the present study, we showed that several prenatal and postnatal conditions or interventions were associated with the development of eating disorders in young children. Recommendations for future studies include identifying environmental risk factors and implementing prevention programs focused on family, caregivers, as well as healthcare professionals. The objective is to allow physicians to efficiently sort out the wide variety of conditions, categorize them for therapy, and when necessary refer patients to specialists in the field.

[Magnet ingestions in children: a French multicenter study]. / Ingestion de corps étrangers aimantés chez l'enfant: enquête multicentrique française.

Digestive complications related to the ingestion of magnetic foreign bodies in children are increasing, especially in Asia and North America. In France, several case reports have been reported since 2008. We conducted a retrospective multicentric study to evaluate the frequency of ingestion of magnet foreign bodies and to describe the complicated cases that have occurred in France over the last 5 years. We report 40 cases of which 60% were multiple magnet ingestions. Eighty-eight percent of the children of the group who had swallowed multiple magnets needed interventional management by endoscopy (33%) or surgery (58%). Only two children (12.5%) of the group who swallowed one magnet required removal. This problem is not uncommon in France (2% of the 1132 foreign bodies investigated in the Toulouse center over 5 years), which justifies clear information for healthcare professionals and caregivers in order to avoid potential intestinal complications. We suggest interventional management or very close monitoring in the cases of multiple magnet ingestion. Meanwhile, in the majority of confirmed cases of simple magnet ingestions, we propose home monitoring.

[Assessment of medical students using a script concordance test at the end of their internship in pediatric gastroenterology]. / Évaluation des étudiants en médecine lors de leur stage en gastro-entérologie pédiatrique par un test de concordance de script.

The Script Concordance Test (SCT) is a tool used to evaluate clinical reasoning in complex medical situations. Our aim was to create the first SCT in pediatric gastroenterology in order to objectively assess medical students. We elaborated a SCT including 31 items divided into ten clinical cases. Topics were chosen within the list comprising the national academic exam. In order to assess medical students, a reference panel was made up of ten residents to establish the scoring process. Answers were noted on a Likert scale, ranging from -2 to +2. Scores were calculated based on the modal response. Depending on the variation of the experts' answers to each item, we classified the questions as correct, incorrect, or uncertain. The SCT was also taken by five GI pediatricians. The results were given as mean/20 ± SEM. The Student t-test was used for the statistical analysis. The scores were 15.35 ± 0.38 and 12.44 ± 0.58 (P=0.0006), respectively, for the reference panel and the students. Scores were unchanged by removing incorrect and uncertain questions. However, the score of the GI pediatricians was 13.37 ± 0.69, significantly lower than the reference panel (P=0.01). The reliability of this SCT is subject to debate. This was the first time the students had taken a SCT, but they considered that this tool was appropriate and in concordance with the objectives. Although the SCT is a useful method, its elaboration can be difficult. It seems important to create a group of teachers to validate the process and eliminate the wide variability.

[Feeding disorders in infants and toddlers: advantages of a joint consultation with pediatrician and psychologist]. / Troubles alimentaires restrictifs du nourrisson et du jeune enfant : avantages d'une consultation conjointe entre pédiatre et psychologue.

Feeding disorders and food refusal can be found in 25% of infants, a minority of these disorders has an organic explanation. Failure to thrive and/or severe malnutrition is found in 3-5% of infants in the general population. The authors describe the various phases of the interdisciplinary therapeutic intervention by underlining the advantages and the objectives to integrate therapeutic approaches across professional boundaries. Caregiver-infant relationship disturbances are certainly the most important factor, but the induced psychosomatic conditions also have a multifactorial etiology. This article points out the specificities of the disorders of infant feeding behaviors and explains the advantages of a joint pediatrician-psychologist consultation compared to separate consultations in pediatrics and child psychiatry.

[Should the whole population be screened for coeliac disease?]. / Faut-il faire un dépistage systématique de la maladie cœliaque dans la population générale ?

To address the issue of mass screening in coeliac disease strict criteria shall be defined. Principles and practice of screening for disease have been defined 40 years ago by Wilson and Jungner, there are still accurate and applied, specially in France for neonatal screening. Screening the whole population for gluten intolerance is not recommended at this time. Aress with gap in scientific knowledge are identified and further prospective epidemiologic studies are needed. These include the timing of screening, defining the natural history of screening-identified asymptomatic patients, developing tools to predict disease onset and disease remission and the potential risks of screening. At the present time, only identification and testing of high-risks groups is recommended.

[When should we introduce gluten into the feeding of the new-born babies?]. / Quand doit-on introduire le gluten dans l'alimentation des nourrissons?

Celiac disease (CD) is an auto-immune enteropathy, triggered in genetically predisposed individuals by the ingestion of dietary gluten. Gluten is the alcohol-soluble protein component of the cereals wheat, rye and barley. CD is a multifactorial condition, originating from the interplay of genetic and environmental factors. The necessary environmental trigger is gluten, while the genetic predisposition has been identified in the major histocompatibility complex region on chromosome 6, with over 90% of CD patients expressing HLA DQ2 and the remaining celiac patients express DQ8. The fact that only about 4 % of DQ2/8-positive individuals exposed to gluten develop CD, has led to the recognition that other genetic and environmental factors are also necessary. In the last few years, several epidemiological studies have suggested that the timing of the introduction of gluten, as well as the pattern of breastfeeding, may play an important role in the subsequent development of CD. Here, we present and review the most recent evidences regarding the effect of timing of gluten introduction during weaning, the amount of gluten introduced and simultaneous breastfeeding, on the development of CD.

[Survey about the perception of the gastroenteritis and the infection due to rotavirus by the mothers in France]. / Enquête sur la perception de la gastro-entérite et de l'infection à Rotavirus par les mères en France.

AIM: To describe the perception of the acute gastroenteritis (AGE) and the interest for the vaccination of the AGE due to Rotavirus. MATERIAL AND METHODS: Observational investigation realized by phone by the IPSOS institute, with 1002 French women of 18 years and more, constituting a representative national sample, having at least a child below 2 years, between 7 and January 31st, 2008. RESULTS: AGE is mainly considered by the mothers questioned as a grave pathology (43.1%) or very grave (51.3%) for the children below 2 years. This perception is bound to the symptoms and to the complications known for the disease. For the questioned mothers, the AGE comes along very often or often with diarrheas (97.2%), vomits (94.3%) or dehydration (94%). Hospitalizations are also perceived as frequent. The quasi-totality of the questioned women (98.3%) considers finally that it is about a very contagious disease (75.4%) or rather contagious (22.8%). The AGE at the child below 2 years provoke very frequently a medical consultation (91.8%), during which some solutions of oral rehydration are prescribed in six cases on 10 (62%). The questioned mothers are for the greater part favorable (86.3%) to a drinkable vaccine to prevent the AGE due to Rotavirus, and 88.1% say that they would intend to protect their child with this vaccine. CONCLUSION: The questioned mothers know the potential gravity of the AGE and a very wide majority of them (86.3%) declare themselves favorable to the prevention of the AGE at Rotavirus by the vaccination.

Prevention of relapse by mesalazine (Pentasa) in pediatric Crohn's disease: a multicenter, double-blind, randomized, placebo-controlled trial.

AIM: This study aimed to test the efficacy of mesalazine in maintaining remission in pediatric Crohn's disease (CD) following successful flare-up treatment. METHODS: In this double-blind, randomized, placebo-controlled trial, 122 patients received either mesalazine 50mg/kg per day (n=60) or placebo (n=62) for one year. Treatment allocation was stratified according to flare-up treatment (nutrition or medication alone). Recruitment was carried out over two periods, as the first period's results showed a trend favoring mesalazine. Relapse was defined as a Harvey-Bradshaw score more than or equal to 5. Time to relapse was analyzed using the Cox model. RESULTS: The one-year relapse rate was 57% (n=29) and 63% (n=35) in the mesalazine and placebo groups, respectively. We demonstrated a twofold lower relapse risk (P<0.02) in patients taking mesalazine in the medication stratum (first recruitment period), and a twofold higher risk in patients taking mesalazine in the nutrition stratum (second recruitment period), compared with the other groups. None of the children's characteristics, which differed across the two recruitment periods, accounted for the between-period variation in mesalazine efficacy. One serious adverse event was reported in each treatment group. CONCLUSION: Overall, mesalazine does not appear to be an effective maintenance treatment in pediatric CD.

[Ingestion of foreign bodies in children. Recommendations of the French-Speaking Group of Pediatric Hepatology, Gastroenterology and Nutrition]. / Ingestion de corps étrangers chez l'enfant. Recommandations du Groupe francophone d'hépatologie, gastroentérologie et nutrition pédiatriques.

Ingestion of foreign bodies is a common pediatric problem. The majority of ingested foreign bodies pass spontaneously. Management of foreign body ingestions varies based upon the object ingested, its location, and the patient's age and past history. Esophageal foreign bodies should be urgently removed because of their potential to cause complications. Ingested batteries that lodge in the esophagus, sharp or pointed foreign bodies in the esophageal or gastric tract, and ingestion of multiple magnets all require urgent endoscopic removal. Flexible endoscopy is the therapeutic modality of choice for most patients. The use of devices such as a latex protector hood or an overtube may facilitate safer extraction of sharp objects.

[Treatment of children with feeding disorders]. / Prise en charge des enfants présentant un refus d'alimentation.

The treatment of children presenting a refusal of feeding is multidisciplinary. This is why the point of view of various speakers were approached at the time of this round table. The gastroenterologists -pediatrician stressed the importance of the clinical data to support the diagnosis of a possible organic pathology and to evaluate the nutritional state. When the denutrition is proven, it is sometimes necessary to have recourse to an artificial enteral feeding. If this one must be prolonged a gastrostomy is preferred. The psychiatrics pointed out the oropharyngeal psychopathologies related to the various feeding disorders met during the childhood, including anorexia, the type of treatment being specific to each nosologic entity. The parent-child's observation in interaction is of primary importance for the diagnosis. The speech therapists evoked the importance of the knowledge of the various stages of maturation of the swallowing and the sensory character of this act to understand the bases of rehabilitation. This rehabilitation is long and does not have to neglect relational dynamics.

[Viral acute diarrhea: clinical and evolutive aspects]. / Diarrhées aiguës virales: aspects cliniques et évolutifs.

The molecular characterization of gastroenteritis viruses has led to advances both in our understanding of the pathogens themselves and in development of a new generation of diagnostics. In developing countries, gastroenteritis is a common cause of death in children under 5 years that can be linked to a wide variety of pathogens. In developed countries, while deaths from diarrhoea are less common, much illness leads to hospitalization or doctor visits. Much of the gastroenteritis in children is caused by viruses belonging to four distinct families: rotaviruses, caliciviruses, astroviruses and adenoviruses. Viral gastroenteritis occurs with two epidemiologic patterns, diarrhoea that is endemic in children and outbreaks that affect people of all ages. Rotavirus infection causes severe gastroenteritis, particularly in infants under six months of age.
