Lien PubMed Bleeding complications after ritual circumcision: about six children
BOCQUET N, CHAPPUY H, LORTAT-JACOB S, CHERON G
2010 - Eur J Pediatr 169(3):359-62
Circumcision is the most common surgical procedure in boys. Even if the procedure is frequent, circumcision can have tragic complications. We report the cases of six children, seen over 1 year at the emergency department for bleeding complication or mutilation after ritual home circumcision. To avoid such complications, it is recommended that circumcision should be performed by doctors trained in this procedure. Parents have to be cautioned about the risks of possible complications after this procedure.

Lien PubMed Length of the treatment and number of doses per day as major determinants of child adherence to acute treatment
CHAPPUY H, TRELUYER JM, FAESCH S, GIRAUD C, CHERON G
2010 - Acta Paediatr 99(3):433-37
Abstract Objective: To determine the rate of aftercare adherence to prescriptions from a paediatric emergency department and to identify predictors for nonadherence. Methods: Patients discharged from a French paediatric emergency department with at least one oral drug prescription were included. A telephone interview questionnaire was used to determine whether the child had received the treatments according to the prescription. Adherence was assessed according to three items: frequency of drug administration, length of treatment and drug administering method. Complete adherence was defined as adherence to the three items mentioned above, and nonadherent as nonadherent to at least one of the items. Influence of age, sex, pathology, language spoken at home, type of medical insurance, type of medication prescribed, diagnosis, dissatisfaction with the explanation of the medical problem, number of prescribed medications, length of the treatment and number of doses per day was assessed. Results: One hundred and five telephone interviews were exploited. The children were 60 boys (57%) and 45 girls (43%). The ages of these 105 children were between 0.2 and 12 years. The most common diagnoses were asthma and pulmonary infection. Complete adherence with the prescription was 36.2%. Three factors were significantly associated with nonadherence (p < 0.05): length of treatment, number of doses per day and male sex. Conclusion: This study suggests that simplifying treatment schedules is an effective strategy for improving compliance in paediatric emergency departments.

Lien PubMed Influence of development, HIV infection, and antiretroviral therapies on the gene expression profiles of ABC transporters in human lymphocytes
GIRAUD C, MANCEAU S, DECLEVES X, GOFFINET F, MORINI JP, CHAPPUY H, BATTEUX F, CHOUZENOUX S, YOUSIF S, SCHERRMANN JM, BLANCHE S, TRELUYER JM
2010 - J Clin Pharmacol 50(2):226-30
The efficacy of drugs acting on lymphocytes like anticancer, immunosuppressive, and antiretroviral drugs depends on their intracellular concentrations, which could be modulated by membrane efflux pumps belonging to the ABC transporter superfamily. The gene expression profiles of 6 main ABC transporters (MDR1, MRP1, MRP3, MRP4, MRP5, and BCRP) were established in lymphocytes from birth to adulthood using blood samples from 57 children and 15 adults (34 and 5 HIV-infected, respectively). Gene expression levels were quantified by quantitative RT-PCR. In adults, the MRP1 gene had the highest expression, followed by the MRP5 gene. BCRP and MRP4 genes were significantly higher expressed at birth than after 1 month of life. Neither HIV infection nor antiretroviral therapies modulated the gene expression profiles of ABC transporters. In conclusion, drugs that are substrates of BCRP and MRP4, like zidovudine, may have an altered efficacy in newborns.

Lien PubMed VIP hypersecretion as primary or secondary syndrome in neuroblastoma: A retrospective study by the Societe Francaise des Cancers de l'Enfant (SFCE)
BOURDEAUT F, DE CARLI E, TIMSIT S, COZE C, CHASTAGNER P, SARNACKI S, DELATTRE O, PEUCHMAUR M, RUBIE H, MICHON J, NEUROBLASTOMA COMMITTEE OF THE SOCIETE FRANCAISE DES CANCERS ET LEUCEMIES DE L'ENFANT ET DE LA
2009 - Pediatr Blood Cancer 52(5):585-90
BACKGROUND: Neuroblastic tumors (NTs) are occasionally associated with watery diarrhea, due to Vasoactive Intestinal Peptide (VIP) secretion. Most reports are single cases and suggest a great homogeny within this sub-group of NTs. PROCEDURES: We conducted a retrospective analysis of the French experience of NTs associated with watery diarrhea due to VIP-secretion. VIP secretion was confirmed by seric dosage and/or immunohistochemistry. RESULTS: Twenty-two patients met the diagnostic criteria between 1988 and 2007. Most of patients suffered from weight loss and metabolic disorders. In 16 cases, digestive symptoms preceded the diagnosis of the tumor ("Primary VIP secreting NTs"); 15 were localized and all showed a differentiated histology. Interestingly, in another 6 patients with high-risk NT, diarrhea occurred at the time of chemotherapy or retinoic acid therapy ("Secondary VIP secreting NTs"). Differentiation in response to treatment was documented in 4 cases. In all cases, only surgical excision of the tumor was able to control the digestive symptoms. Twenty children are alive and 13 are disease-free. CONCLUSION: VIP secreting NTs are usually associated with differentiation; they can also secondarily arise from a high-risk tumor upon treatment. Primary surgery constitutes first-line treatment.

  Neurological consequences of vitamin B12 deficiency and its treatment
CHALOUHI C, FAESCH S, ANTHOINE-MILHOMME MC, FULLA Y, DULAC O, CHERON G
2008 - Pediatr. Emerg. Care 24(8):538-541
In developed countries, the vitamin B12 deficiency usually occurs in children exclusively breast-fed, whose mothers are vegetarians, causing low stores of vitamin B12. Symptoms of vitamin B12 deficiency appear during the second trimester of life and include failure to thrive, lethargy, hypotonia, and arrest or regression of developmental skills. A megaloblastic anemia can be present. One half of the infants exhibit abnormal movements before the start of treatment with intramuscular cobalamin, which disappear 1 or 2 days after. More rarely, movement disorders appear a few days after treatment, whereas neurological symptoms are improving. These abnormal movements can last for 2 to 6 weeks. If not treated, vitamin B12 deficiency can cause lasting neurodisability. Therefore, efforts should be directed to preventing deficiency in pregnant and breast-feeding women on vegan diets and their infants by giving them vitamin B12 supplements. When preventive supplementation has failed, one should recognize and treat quickly an infant presenting with failure to thrive and delayed development.

  Children's views on their involvement in clinical research
CHAPPUY H, DOZ F, BLANCHE S, GENTET JC, TRELUYER JM
2008 - Pediatr. Blood Cancer 50(5):1043-1046
OBJECTIVE: To examine the level of children's understanding of informed consent in clinical trials and factors that may influence these processes. DESIGN: Twenty nine children who were included in clinical trials for treatment of cancer or HIV, were offered the possibility to complete a semidirective interview, with parental permission. METHODS: Children's understanding was measured by a score of 0-9 including items required to obtain a valid consent according to French and European legislations. RESULTS: Children were 8.5-18 years old (13.6 +/- 2.8 years). The higher percentage of understanding was obtained for the study objectives (n = 18, 62%), the risks (n = 17, 58%), the potential self-benefits (n = 18, 62%) and the potential benefits to other children (n = 17, 58%). The lower percentage of understanding was obtained for the procedures (n = 5, 17%), the possibility of alternative treatments (n = 9, 31%), the duration of participation (n = 6, 21%), their right to withdraw (n = 6, 21%), and the voluntary participation (n = 6, 21%). Sixteen children (55%) thought that the given information was adequate. Understanding was significantly correlated with child's age (r = 0.65; P = 0.0001) and the mean score was higher in patients over 14 years old compared to patients under the age of 14 (4.4 +/- 2.4, n = 14 vs. 2.6 +/- 2.6, n = 15, P < 0.05). The mean score was also higher in children when informed consent was sought some time after the diagnosis (>7 days) rather than at the same time (<7 days) (score: 4.14 +/- 2.59 n = 21 vs. 1.87 +/- 2.03 n = 8; P = 0.03). The clarity of information perceived by children did not influence their understanding (score: 3.6 +/- 2.6 n = 14 vs. 3.5 +/- 2.7 n = 15; P = 0.91). CONCLUSION: Children have an incomplete understanding of the elements included in the informed consent forms. Understanding is related to age and timing of informed consent.

  Pharmacokinetic modelling of the placental transfer of nelfinavir and its M8 metabolite: a population study using 75 maternal-cord plasma samples
HIRT D, URIEN S, JULLIEN V, FIRTION G, CHAPPUY H, REY E, PONS G, MANDELBROT L, TRELUYER JM
2007 - Br. J. Clin. Pharmacol. 64(5):634-644
AIMS: A population pharmacokinetic model was developed to characterize the transfer of nelfinavir and its active metabolite M8 from maternal to cord plasma and amniotic fluid. METHODS: Concentration data were obtained from 75 women on the day of delivery and for whom maternal, umbilical plasma and amniotic fluid samples were collected. Data from 53 pregnant, 61 nonpregnant and seven consecutively pregnant and non pregnant women were then added to the database, the contents of which were analyzed using NONMEM. RESULTS: Nelfinavir and M8 concentrations in maternal plasma, umbilical plasma and amniotic fluid were described by six connected compartments. Mean (% intersubject variability) population estimates were: absorption rate 00.67 h(-1), lag time 00.87 h, oral clearance and volume of distribution: 39.5 l h(-1) (53%), and 557 l for non pregnant and pregnant women, respectively, and 115 l h(-1) (132%) and 1626 l, respectively, on the day of delivery, M8 formation clearance 0.77 l h(-1) and M8 elimination rate constant 03.41 h(-1) (74%). For nelfinavir and M8, respectively, the mother-to-cord parameters were 0.058 l h(-1) (34%), and 00.35 h(-1) (76%), the cord-to-amniotic fluid rate constants were 0.23 and 00.59 h(-1), and the elimination rate constants from amniotic fluid were 0.36 and 00.49 h(-1). The nelfinavir fetus : maternal concentration ratio was 25% for maternal concentrations between 0.1 and 2.5 mg l(-1), between the 31 and 41st week of gestation. CONCLUSIONS: The low transfer of nelfinavir from the placenta is unlikely to protect the fetus from vertical HIV-1 transmission.

  Metered-dose inhaler with spacer versus nebulization for severe and potentially severe acute asthma treatment in the pediatric emergency department
SANNIER N, TIRNSIT S, COJOCARU B, LEIS A, WILLE C, GAREL D, BOCQUET N, CHÉRON G
2007 - Rev. Fr. Allergol. Immunol. Clin. 47(2):64-71
Objective.- To compare treatment with beta 2 agonist delivered either by a spacer device or a nebulizer in children with severe or potentially severe acute asthma. Methods.- In this randomized trial, children 4 to 15 years, cared for in the emergency department for severe or potentially severe acute asthma, received 6 times either nebulizations of salbutamol (0.15 mg/kg) or puffs of a beta 2 agonist (salbutamol 50 mu g/kg or terbutaline 125 mu g/kg). The primary outcome was the hospitalization rate. Secondary outcomes included percentage improvement in Bishop score, in PEF, SaO(2), respiratory and heart rates, side effects, length of stay and relapses 10 and 30 days later. Results.- Groups did not differ for baseline data. There were no significant differences between the 2 groups (nebulizer N = 40, spacer N = 39) for baseline characteristics before emergency department consultation except for length of acute asthma in the spacer group. Clinical evolution after treatment, hospitalization rate, relapse were similar including the more severe subgroup. In the spacer group, tachycardia was less frequent (P < 0.02). The overall length of stay in the emergency department was significantly shorter (148 +/- 20 vs 108 +/- 13 min, P < 10(-9)). Conclusions.- The administration of beta 2 agonist using a metered-dose inhaler with spacer is an effective alternative to nebulizers for the treatment of children with severe or potentially severe acute asthma in the emergency department. Time gained can be used for asthma education. (C) 2007 Publie par Elsevier Masson SAS.

  Delay in diagnosis of imported Plasmodium falciparum malaria in children
CHALUMEAU M, HOLVOET L, CHERON G, MINODIER P, FOIX-L'HELIAS L, OVETCHKINE P, MOULIN F, NOUYRIGAT V, BREART G, GENDREL D
2006 - Eur. J. Clin. Microbiol. Infect. Dis. 25(3):186-189
The study reported here prospectively evaluated the time-to-diagnosis of imported Plasmodium falciparum malaria in children in seven French pediatric emergency departments during a 1-week period. For the 29 patients included, the mean patient, doctor and total delays were 3.1, 1.5 and 4.7 days, respectively. The late medical diagnosis for 11 patients was mainly due to the treating physician's failure to consider malaria, despite having been informed that the child had been in an endemic area, and erroneously making a diagnosis of viral infection. The five patients who were diagnosed correctly without delay had higher mean platelet counts than the others (206,000 vs 118,541/mm(3); p=0.008). The results indicate that greater awareness of the risk of malaria in returning travelers may help reduce delays in diagnosis and its consequences.

2006 - Archives Pédiatrie 13(12):1566-1571
OBJECTIVE: Fever is a common cause of children visits to emergency units. Clinical evaluation does not always eliminate a bacterial infection. Among blood markers, several publications showed the interest of CRP. This study was undertaken to evaluate correlation between two techniques of CRP, one by usual technique at the laboratory and the other by a rapid test, and to evaluate the impact of this rapid test for febrile children at the emergency room, when a hospitalization was not immediately decided. MATERIAL AND METHODS: The study was undertaken in 2004-2005 in eight emergency paediatric units in Ile-de-France concerning febrile children during two periods. In period A, children had at the same time a CRP dosage through two methods, whereas in period B, only a rapid CRP test was first managed. The test used was NycoCard CRP Single test (Progen Biotechnique). RESULTS: Between September 2004 and June 2005, 572 children were included, 268 in period A and 304 in period B. Comparison of CRP results by the two methods showed for 247 children (93%) a fairly good linear correlation (r: 0.929). Blood cell count was the most often prescribed test (99.4 vs 10.5%). Conversely to chest radiography, blood culture, fibrinogen and urinary test were significantly most frequent in period A. The average cost of the additional examinations was 2.6 times more important during the first period. Duration of children management in the units was approximately two times shorter when rapid CRP test was used (199.7+/-92.8 vs 103.5+/-98.6 min). CONCLUSION: This study shows the interest of rapid CRP test for febrile children in the emergency units, and has to be confirmed in ambulatory paediatric practice.

  Prospective comparison of child asthma education in the emergency department and at scheduled follow-up consultation
COJOCARU B, DE BLIC J, SCHEINMANN P, CHERON G
2006 - Archives Pédiatrie 13(8):1112-1117
OBJECTIVES: To assess asthma control in asthmatic children attending the emergency department and to compare it with that for children with scheduled specialist follow-up. POPULATION AND METHODS: Between September 2002 and September 2003, we included asthmatic children aged 6 to 16 years, attending the emergency department (group U) or pulmonology follow-up appointments (group C) at Necker Hospital, Paris, France. We used the Asthma Therapy Assessment Questionnaire (ATAQ), completed by the parents and children aged 10 years and over. RESULTS: We interviewed 156 families and included 144 (92%) in the final analysis (77 in group U). The 2 groups did not differ in age, sex ratio, age at onset and asthma diagnosis and the frequency of asthma attacks. Children in group U received less daily maintenance treatment (P<0.01) but reported more severe asthma (P<0.05). They had also experienced fewer investigations for their asthma (fewer lung function tests P=0.01 and allergy tests P=0.001). The children in group C had better controlled asthma, as assessed by both the children themselves and their parents. They also had fewer problems relating to the behavior, communication and treatment control domains. The assessment of children and parents were similar in all areas except communication. The children considered their communication problems to be more serious than their parents did. Age-related differences were observed, with older children's parents having more difficulties in all domains investigated. CONCLUSION: Clinicians should consider assessing asthma control in children attending the emergency department. There is clearly an opportunity to improve the quality of asthma education for these children. Clinicians could provide children with a written plan of action for asthma attacks and information about daily self-management. Improving communication between children, their parents and doctors should be considered a key educational project.

  Management of intussusception in France in 2004: investigation of the Paediatric Infectious Diseases Group, the French Group of Paediatric Emergency and Reanimation, and the French Society of Paediatric Surgery

2006 - Archives Pédiatrie 13(12):1581-1588
OBJECTIVES: To describe the different pathways of management of intussusception (IS) in infants and children in metropolitan France and to identify paediatric emergency centres that might constitute a surveillance network for IS. MATERIAL AND METHODS: A questionnaire was sent to 273 paediatric emergency centres distributed across France in 2005. Modalities of diagnosis and treatment of IS had to be precised. RESULTS: One hundred and sixty-seven centres (61.2%) responded. The response was given by 131 paediatricians (78.4%) and 36 surgeons (21.6%) working in 38 universitary hospitals (22.7%) and 129 general hospitals (77.2%). The mean number of IS treated in each centre in 2004 was 11+/-13.5 (extr. 0 to 70; median 6). Diagnosis of IS required a collaboration between medical and surgical teams in 51.5% of the centres, but in 40.1% the sole medical team was in charge of the diagnosis. Ultrasonography is used for diagnosis by 98.8% of the centres. Reduction with hydrostatic enema and eventually surgery was performed in the same hospital in 44.3%. Other centres systematically or frequently transferred the patients for reduction, mostly towards universitary hospitals (90%). CONCLUSION: The procedures of IS diagnosis are the same everywhere in France but the pathways of therapeutic management do vary, depending on the availability of surgeons and anaesthetists trained in paediatrics on each site. These disparities will probably change with the implementation of the new plan for sanitary organization in children and adolescents in France. Labellized paediatric emergency centres will gather more surgical patients and could eventually constitute an effective surveillance network for IS.

  Pregnancy-related effects on nelfinavir-M8 pharmacokinetics: a population study with 133 women
HIRT D, TRELUYER JM, JULLIEN V, FIRTION G, CHAPPUY H, REY E, PONS G, MANDELBROT L, URIEN S
2006 - Antimicrob. Agents Chemother. 50(6):2079-2086
A relationship between nelfinavir antiretroviral efficacy and plasma concentrations has been previously established. As physiological changes associated with pregnancy have a large impact on the pharmacokinetics of many drugs, a nelfinavir population study with women was developed, and the large intersubject variability was analyzed in order to optimize individual treatment schedules for this drug during pregnancy. A population pharmacokinetic model was developed in order to describe the concentration time course of nelfinavir and its metabolite M8 in pregnant and nonpregnant women. Individual characteristics, such as age, body weight, and weeks of gestation or delivery, which may influence nelfinavir-M8 pharmacokinetics were investigated. Data from therapeutic drug monitoring in 133 women treated with nelfinavir were retrospectively analyzed with NONMEM. Nelfinavir pharmacokinetics was described by a one-compartment model with linear absorption and elimination and M8 produced from the nelfinavir central compartment. Mean pharmacokinetic estimates and the corresponding intersubject percent variabilities for a nonpregnant woman were the following: absorption rate, 0.83 h(-1); absorption lag time, 0.85 h; apparent nelfinavir elimination clearance (CL(10)/F), 35.5 liters/h (50%); apparent volume of distribution (V/F), 596 liters (118%); apparent formation clearance to M8 (CL(1M)/F), 0.65 liters/h (69%); and M8 elimination rate constant (k(M0)), 3.3 h(-1) (59%). During pregnancy, we observed significant increases in nelfinavir (44.4 liters/h) and M8 (5 h(-1)) elimination but unchanged nelfinavir transformation clearance to M8, suggesting an induction of CYP3A4 but no effect on CYP2C19. Apparent nelfinavir clearance and volume showed a twofold increase on the day of delivery, suggesting a decrease in bioavailability on this day. The M8 elimination rate was increased by concomitant administration of nonnucleoside reverse transcriptase inhibitors. A trough nelfinavir plasma concentration above 1 mg/liter was previously shown to improve the antiretroviral response. The Bayesian individual pharmacokinetic estimates suggested that the dosage should not be changed in pregnant women but may be doubled on the day of delivery.

Ingestion of foreign body has often no consequence. We report on a case in an 11-month-old girl who was referred for mild hematemesis and anorexia. Upper digestive tract endoscopy found a small metallic foreign body in the gastric antrum. After its removal, all symptoms disappeared. It is usually recommended to remove foreign bodies by endoscopy when they are in esophageal position, or are more than 3 to 5 cm long, or have a shape that may hurt the gut mucosa. Although rare, a gastric foreign body should be searched for in face of an upper gastrointestinal bleeding in an infant.

  Treatment of exacerbation of asthma: what are today's issues?

During past decades, major progress has been accomplished in the management of acute asthma. Most recent recommendations include evidence-based rationale. The improved quality of clinical guidelines makes them efficient models for medical education. The pediatric pharmacopoeia provides a great variety of choices of drugs as well as for asthma medical devices. These innovations dramatically facilitated the medical management of asthmatic children, but they did not solve all problems. Physicians now use higher doses of salbutamol, but the early prescription of systemic glucocorticoids for moderate exacerbation of asthma is still underused, given the most recent clinical guidelines and meta-analysis. Furthermore, repeated emergency department visits to the wards and lack of primary care physician should systematically be appraised when evaluating severity, as they are both major risk factors for severe exacerbations, even though they are not considered in acute asthma severity scores. Finally, initiating (or reinforcing) patient education at the time of exacerbation also presents important challenges, as emergency visits are a favorable moment to commence the therapeutic education of the child and his family. Indeed, framing the controller medications and educating families about how to manage the disease and to improve their domestic environment are the genuine tools available for the prevention of asthma exacerbations, and particularly those most severe.

Objectives. - To study the compliance of prescription, the efficacity and the adverse events of oral morphine used in the pediatric emergency departement (ED) in traumatic pains. Method. - This prospective study was conducted in the ED from october 2002 to september 2003. Children aged six months to 16 years with a visual analogic scale (VAS) score higher than 70 or with a traumatic member deformation received oral morphine (0,5 mg/kg). Pain was assessed every 30 minutes using two scales: behavioral observation by the faces scale and objective pain scale (OPS) for children less than five years, behavioral observation by the faces scale and self-report by VAS for children older than five years. The compliance of prescription, the pain scores and the adverse events were studied. Results. - Ninety-one children received oral morphine and seventy-four children were studied. Seventy per cent of prescriptions were in accordance with the recommandations. For patients younger than five years a rapid decrease of pain was observed in thirty minutes. The pain's reduction was respectively 79 and 84% with faces scale and OPS when they left ED. For children older than five years, pain's reduction was more important and more rapid when pain assessment was made by nurses than when it was self-reported in the first hour (pain reduction 58,2 and 36,1%). When leaving, pain reduction was the same with the two different assessments. No major adverse event was noted. Conclusion. - Use of oral morphine in ED is simple, with a few numbers of adverse events. None was severe. Efficiency is correct after 30 to 60 minutes.

  Analgesia in the pediatric emergency department
CHERON G, COJOCARU B, BOCQUET N
2004 - Archives Pédiatrie 11(1):70-73
Pain concerns more than 50% of the children cared in the emergency unit. After evaluation, it has to be cured with drugs adapted to its level and its origin. Residual pain needs therapeutic adjustment. The goal is to allow the child to restart his activities. A preventive sedation analgesia is necessary when a painful exam is to be performed, either for diagnosis or therapeutic purpose. For this goal ideal analgesics, either for monotherapy or associated, are easily and painlessly administered. They have rapid onset of action, brief half-life, predictable, effective analgesic properties without side effects and they are quickly reversible. These drugs do not exist and every sedation procedure has a risk of hypoxemia. With the human and equipment's investment an emergency department should be able to ensure that procedures are performed in children under sedation with a standard of safety that is similar to general anaesthesia. The main drawback in a well-organised system should be a significant children's rate for which general anaesthesia is preferred.

2004 - Archives Pédiatrie 11(2):157-161
Injuries to the lower extremity are frequent. They present as pain, reduction of joint function, alteration in gait. Most of the orthopaedic emergencies for teenagers are related to trauma. For younger children, a history of recent fall is prevalent but the non traumatic orthopaedic conditions are especially important to investigate when the reported injury is minor or when onset of symptoms is delayed.

  Smoking and sudden infant death syndrome
CHERON G, TIMSIT S
2003 - J. Gynécol. Obst. Biol. Reprod. 32(1 Pt 2):33-40
Assessment of the causation relationship between two phenomena requires the demonstration of an epidemiological association, a temporal and asymmetric sequence, and a biological gradient and identification of the biological mechanism(s). All epidemiological studies on sudden infant death syndrome (SIDS) and smoking have encountered major bias and difficult data interpretation but they all have estimated that maternal smoking caused a 2 to 3-fold increased risk of SIDS. Nicotine may interact with non-neuronal nicotinic receptors in the lung, peripheral nicotinic cholinergic and adrenergic chemoreceptors, and brainstem nuclei and has been largely studied. More accurate knowledge concerning the biochemistry and specific features of nicotinic receptors will be useful to explain the way nicotine alters breathing at rest and during hypoxia. Uncertainty about the casual relationship in no way means the fight against smoking is not warranted.

  Asthma in older children and adolescents seen in an Emergency Room
CHERON G, TIMSIT S, COJOCARU B, SANNIER N
2002 - Rev. Fr. Allergol. Immunol. Clin. 42(6):611-618
During the obligatory passage from being his parent's responsibility to assuming his own therapeutic autonomy, the asthmatic adolescent, as a result of his disease, is exposed to specific risks, including both morbidity and mortality. These risks arise from his personal feelings about his asthma and from his family's beliefs as well. The entire range of morbidity is important : school absenteeism, decreased activity, persistent asthma and inadequate drug prescriptions. Dissatisfaction is frequent, e specially regarding patient-provider communication and knowledge. New strategies of care and education for this age group have to be explored.

  Effet du racecadotril sur le recours aux soins dans le traitement des diarrhées aigües du nourrisson et de l'enfant
COJOCARU B, BOCQUET N, TIMSIT S, WILLE C, BOURSIQUOT C, MARCOMBES F, GAREL D, SANNIER N, CHERON G
2002 - Arch. Pediatr. 9(8):774-779
BACKGROUND: The treatment of diarrhoea relies on the maintenance or restoration of hydration with maintenance of an adequate nutritional intake. Racecadotril has been shown to reduce the stools output during acute diarrhoea. The present work was aimed at measuring the number of emergency department visits for acute diarrhoea either the children received racecadotril or not. METHOD: Racecadotril and rehydration were compared with rehydration alone in children aged three months to three years who had acute diarrhoea and were evaluated in the emergency department (ED). The primary end point was the number of medical exams during the week after starting treatment. Secondary end points were the number of stools during the first 48 hours, the duration of the diarrhoea and the weight on day 7. RESULTS: One hundred and sixty-six children were alternatively randomized to the treated and the control groups. There was no difference for age, degree of dehydration and length of illness before the first visit between the groups. Whatever type of rehydration (oral or i.v.), the treated group had a significant lower number of stools (p < 0.001) and a faster recovery (p < 10(-9)). The children receiving racecadotril needed less additional ED visits for the same episode (p < 0.05). There was no difference for the weight-gain on day 7. CONCLUSIONS: This study demonstrates the efficacy of racecadotril as adjuvant therapy to oral and i.v. rehydration in the treatment of acute diarrhoea and a fewer emergency department second visit before recovery.

  Nurse's care of acute asthma in the pediatric emergency department
TIMSIT S, PIGNARD L, DESGRANGES L, MARCHAC V, COJOCARU B, CHERON G
2002 - Rev. Fr. Allergol. Immunol. Clin. 42(6):623-628
Acute asthma represents 5% of visits to pediatric emergency departments. On arrival in the Emergency Department, the nurse must recognize the most seriously affected children, using a simple verbal questionnaire. Both the pediatrician and the nurse are responsible for the care and observation of the patients. The treatment plan includes nebulized beta2mimetics, administration of a corticosteroid, and oxygen when necessary. The nurse is responsible for evaluating the patient's progress and being alert for complications. She has to measure respiratory and cardiac rhythms, peak flow and transcutaneous O-2 pressure repeatedly. The child can be discharged with minimal risk of an exacerbation only if his respiratory status is fully improved and remains stable one hour after the last nebulization (more than 80% of cases). In other cases, the patient will be hospitalised in the respiratory disease unit for further treatment. (C) 2002 Editions scientitiques et medicales Elsevier SAS. All rights reserved.

  Apport du bromure d'ipratropium dans la prise en charge des crises d'asthme aux urgences
TIMSIT S, SANNIER N, BOCQUET N, COJOCARU B, WILLE C, BOURSIQUOT C, GAREL D, MARCOMBES F, CHERON G
2002 - Arch. Pediatr. 9(2):117-125
BACKGROUND: To determine if the addition of ipratropium bromide in the emergency department (ED) for the treatment of childhood asthma reduces rates of hospitalization and relapses for moderate and severe exacerbations. METHODS: Patients were given an oral corticosteroid treatment (2 mg/kg) and received every 20 minutes either three nebulizations with albuterol (0.15 mg/kg) and ipratropium bromide (250 micrograms) or six nebulizations with albuterol alone (control group). The primary end point was the need for hospitalization, additional nebulizations or a relapse during the following week. Secondary end point included the effect of age. RESULTS: One hundred and forty three children, two to 15 years old, were randomized to ipratropium or control groups and 121 were evaluated on day seven. As a whole, the control group was less often hospitalized or in relapse than those treated with three nebulizations of albuterol and ipratropium (17.5% vs 37.9%, p < 0.02). The ipratropium group reached the same result after three additional albuterol nebulizations. The benefit of anticholinergic therapy was observed for children less than six years of age who had a similar rate of success (73.5 vs 75.7%). CONCLUSION: The association of ipratropium bromide to the first three doses of the albuterol protocol for acute asthma did not act as well as six nebulizations of albuterol alone. The effect was age dependent and two to six years old children needed more attention. Nevertheless the hospitalization rate did not support the use of ipratropium compared with repeated albuterol nebulizations.

  Spontaneous pneumomediastinum in children
CHALUMEAU M, LE CLAINCHE L, SAYEG N, SANNIER N, MICHEL JL, MARIANOWSKI R, JOUVET P, SCHEINMANN P, DE BLIC J
2001 - Pediat. Pulm. 31(1):67-75
Spontaneous pneumomediastinum (SPM) is rare in children, mainly affecting male adolescents. It is usually secondary to alveolar rupture in the pulmonary interstitium, followed by dissection of gas towards the hilum and mediastinum. Many pathological and physiological events can lead to alveolar rupture, but the most common cause in children is asthma. The clinical diagnosis is based on the symptom triad of chest pain, dyspnea, and subcutaneous emphysema. and is also based on Hamman's sign. The diagnosis is confirmed by chest radiography. The main differential diagnosis is esophageal perforation, which requires an esophagogram with contrast when there is the slightest doubt in the diagnosis. Spontaneous pneumomediastinum generally resolves spontaneously within a few days, meaning that ambulatory treatment is usually appropriate. Management consists of treating the underlying cause (if identified), rest, analgesics, and simple clinical monitoring. Predisposing factors should be identified and controlled to prevent recurrence. Cases of idiopathic SPM necessitate diagnostic pulmonary function tests after the acute episode, to establish whether the child has asthma. (C) 2000 Wiley-Liss. Inc. [References: 89]

Drugs for pediatric emergencies are useful for respiratory (croup, asthma), cardiologic (hypertensive crisis, acute congestive heart failure, arrhythmias, hypoxic spells), neurologic (seizures), metabolic (dehydration, hypoglycaemia), infectious (meningococcemia) or allergic (anaphylaxis) distresses. Pain management is always important whether to relieve or to prevent the discomfort which would happen during diagnosis or therapeutic procedures.

2001 - Archives Pédiatrie 8(9):922-928
Background. - Each year, a quarter of the children younger than 24 months has respiratory syncytial virus bronchiolitis. The morbidity among high-risk infants and the possible association with the development of asthma lead to propose preventive measures whose cost-effectiveness relationship is unknown. The present work was aimed at measuring costs of a first attack of bronchiolitis. Method. - For children less than two years visited in the emergency department, direct and indirect costs were measured according to the 'Securite Sociale' prices. Associated morbidity, the management of care (inpatient versus outpatient), outpatients' outcome two weeks after the visit, socioeconomic data were recorded. Results. - One hundred eighty three children have been studied. The length of stay for 40 hospitalizations was 7.6 +/- 4.3 days. Direct costs were 37 200 +/- 22-000 FF for inpatients, and 1286 +/- 633 F for outpatients. For 113 outpatients' families, indirect costs were 49 working days lost. The way the child was looked after and the unemployment rate in the study were similar to data provided by the National Institute of Statistics and Economic Studies. Conclusion. - Because of the variability of the hospitalization rate from one setting to another, overall costs of the epidemic cannot be evaluated. For the policymaker the greatest costs come from the outpatient care. Others studies will be necessary to evaluate the price of future preventive measures.

Aims-To determine the extent of off label and unlicensed drug use in French office based paediatric practice. Methods-A prospective one day survey of all written prescriptions, for patients under 15 years, among 95 office based paediatricians in the Paris, France metropolitan area. Main outcome measures were: comparison of the use of each drug with its product Licence for age, indication, dose, and route of administration. Results-A total of 2522 prescriptions were administered to 989 patients; 844 (33%) were used either in an unlicensed (4%) or an off label (29%) manner. A total of 550 (56%) paediatric patients received one or more off label prescriptions. Conclusions-Off label prescriptions (that is, outside the terms of the Summary of Product Characteristics) are widespread in office based paediatric practice, while unlicensed drug use is rare in our study. New regulations in the licensing process in Europe are needed to allow children to receive drugs that have been fully evaluated in their specific age group. [References: 29]

  Etiological and pathogenetic basis of the management of apparent life-threatening events in infants
CHERON G
2000 - Archives Pédiatrie 7(12):1339-1343
Apparent life-threatening events in an infant require: 1/ to determine the seriousness of the event; 2/ to identify ifs etiology; 3/ to evaluate the risk of recurrence and the need for appropriate preventive measures. Management mainly depends upon the determination of the etiology and the understanding of the pathogenetic mechanism. Gastroesophageal reflux is the main etiology. Therefore whenever symptoms of gastroesophageal reflux are present, this has to be considered as the first etiological hypothesis. Other etiologies will be searched for if orientating symptoms or anamnesis information is present, leading to specific investigations. (C) 2000 Editions scientifiques et medicales Elsevier SAS.

  Ontogenesis of cyp2c-dependent arachidonic acid metabolism in the human liver: relationship with sudden infant death syndrome
TRELUYER JM, BENECH H, COLIN I, PRUVOST A, CHERON G, CRESTEIL T
2000 - Pediat. Res. 47(5):677-683
A modification of the human monooxygenase system have been previously associated with the sudden infant death syndrome (SIDS): the hepatic CYP2C content was markedly enhanced and resulted from an activation of CYP2C gene transcription. To determine the possible consequence of the up-regulation of CYP2C in SIDS, we examined the metabolism of arachidonic acid (AA) an endogenous substrate of CYP2C involved in the physiologic regulation of vascular tone. The overall AA metabolism was extremely low during the fetal period and rose after birth to generate 14,15 epoxyeicosatrienoic acid (EET), 11,12 EET and the sum of 5,6 dihydroxyeicosatrienoic acid (diHETE)+omega/omega-1 hydroxy AA. In SIDS, the accumulation of CYP2C proteins was associated with a significant increase in the formation of 14,15 and 11,12 diHETE, which were shown to be supported by individually expressed CYP2C8 and 2C9 and HETE1 (presumably 15 METE). This increase was markedly inhibited by addition of sulfaphenazole, a selective inhibitor of CYP2C9. So, we propose that the higher CYP2C content in SIDS stimulates the production of EETs and diHETEs and might have severe pathologic consequences in children. [References: 36]

To evaluate the ambulatory management of ileo-colic intussusception in infants and children, a retrospective study over 3 years of 113 children treated for ileo-colic intussusception ill a paediatric emergency department was undertaken with the aim of shortening the length of stay. A total of 113 children aged 10 days to 9 years (median 12 months) were treated for intussusception between January 1993 and December 1996. None had septic shock or peritoneal aeric effusion. Barium enema reduction was attempted in all patients. Successful reduction rate was 81%. Fifty patients (44.2%) were completely ambulatory managed and 42 were hospital-supervised after successful enema reduction. Twenty-one children underwent laparotomy after failure of enema. With the ambulatory device, costs were reduced ($1000/case) compared with conventional in-patient treatment.

1999 - Med. Decis. Making 19(4):399-410
Background. An organ dysfunction (OD) scoring system for critically ill children is not yet available, and the method for developing such a system is not well defined. The aim of this study was to compare two developmental methods for assessing OD in critically ill children. Methods. Consecutive admissions between January and May 1997 in three French and Canadian pediatric intensive care units (PICUs) were studied prospectively. Physiologic data were selected using a Delphi method; the most abnormal values during PICU stay were recorded. The outcome measure was the vital status at PICU discharge. Six organ systems were studied: hepatic, cardiovascular, renal, hematologic, respiratory, and neurologic. For each of the six organ systems, the PEdiatric Multiple OD (PEMOD) system included one variable and the PEdiatric Logistic OD (PELOD) system included several variables. Severity levels and relative weights of ODs were determined according to the mortality rate (PEMOD) or by logistic regression (PELOD). Results. There were 594 admissions, including 51 deaths (9%). Severity levels and relative weights of ODs were: four levels graded from 1 to 4 for the PEMOD system and three levels with scores of 1, 10, and 20 for PELOD system. For both systems, calibrations were good (p = 0.23 and p = 0.44 respectively). The PELOD system was more discriminant than the PEMOD system (areas under the ROC curves 0.98 and 0.92, respectively, p < 10(-5)). Moreover, with the PEMOD system, four ODs did not contribute significantly to the prediction of PICU outcome. Conclusions. The PELOD system was more discriminant and had the advantage of taking into account both the relative severities among ODs and the degree of severity of each OD. [References: 39]

1999 - Ann. Pédiatr. 46(2):104-112
Background:evaluation of ambulatory management with a single parenteral antibiotic treatment for uncomplicated pyelonephritis in children. Population and methods: Retrospectively analysis of 225 children with a suspicion of uncomplicated pyelonephritis between 1/1/95 to 30/6/96. The children were treated with a single dose per day of ceftriaxone for four days, followed by ten days of oral antibiotherapy. Fever duration, repeat urine culture, cystourethrography, surgical treatment and relapse were monitored. Results: 130 children from I month to 15 years met criteria commonly accepted for pyelonephritis diagnosis. After 12 months of age pyelonephritis was more common in girls and 43% of the population were younger than 1 year. E, coli. was isolated in 94% of them. Fever disappeared and urine was sterilized within 72 hours. Cystourethrography was undertaken in 112 cases. One posterior urethral valves and 43 vesicoureteral reflux (38%) were discovered. A third of them was surgically repaired during follow up. One relapse occured 3 weeks later. Follow-up from 9 to 27 month was possible for 104 children (80%). Conclusion : When families fully understand the treatment, ambulatory management of common pyelonephritis with one parenteral antibiotic is safe, on condition families agreed to the treatment modes. To chose between one or two antibiotic strategies, further studies with early and late DMSA renal scans are needed to detect renal scar incidence. [References: 29]
