[Cesarean sections in the Centre-Val de Loire region: Practices and indications-the Robson Classification]. / Césarienne en Centre-Val de Loire ­ Pratiques et Indications ­ Classification de Robson.

BACKGROUND: To study the cesarean section (c-section) practices in the French Centre-Val de Loire region: incidence of planned c-section and rate variations between maternities, incidence of potentially avoidable cesarean sections. METHODS: The data were extracted from the 2016 regional birth register, which permitted classification of each planned c-section according to the pre-existing risk of c-section (high or low) as defined by the Robson classification. To enhance the data, especially the indications for c-section, which are not included in the register, a survey was conducted from September 2016 to February 2017 in all of the 20 maternities in the region. RESULTS: In 2016, nearly 26,000 women gave birth in the CVL region, of whom 19.2% by c-section (7.0% planned c-sections). The planned c-section rate was higher for breech presentation and scarred uterus, and decreased according to level of the maternity (I 41% - II 35% - III 32%). Concerning the c-section indications, 1,979 c-sections were studied during the period (18.6% of births), including 762 planned c-sections (7.1% of births). Among them, 246 (32%) were potentially avoidable, mainly isolated indications of scarred uterus with only one previous c-section or breech presentation, and 17 due to unfavorable radiologic pelvimetry in nulliparous women. CONCLUSION: Specific actions were identified: targeted use of radiologic pelvimetry, targeted c-section on scarred uterus with only one previous cesarean section or breech presentation, as recommended by the national guidelines. The Robson classification should be widely used to evaluate and enhance practices, in particularly through painstakingly interpreted inter-maternity comparisons.

[Using cancer case identification algorithms in medico-administrative databases: Literature review and first results from the REDSIAM Tumors group based on breast, colon, and lung cancer]. / Recherche d'algorithmes d'identification des cancers dans les bases médico-administratives : premiers résultats des travaux du groupe REDSIAM Tumeurs sur les cancers du sein, du côlon-rectum et du poumon.

BACKGROUND: The development and use of healthcare databases accentuates the need for dedicated tools, including validated selection algorithms of cancer diseased patients. As part of the development of the French National Health Insurance System data network REDSIAM, the tumor taskforce established an inventory of national and internal published algorithms in the field of cancer. This work aims to facilitate the choice of a best-suited algorithm. METHOD: A non-systematic literature search was conducted for various cancers. Results are presented for lung, breast, colon, and rectum. Medline, Scopus, the French Database in Public Health, Google Scholar, and the summaries of the main French journals in oncology and public health were searched for publications until August 2016. An extraction grid adapted to oncology was constructed and used for the extraction process. RESULTS: A total of 18 publications were selected for lung cancer, 18 for breast cancer, and 12 for colorectal cancer. Validation studies of algorithms are scarce. When information is available, the performance and choice of an algorithm are dependent on the context, purpose, and location of the planned study. Accounting for cancer disease specificity, the proposed extraction chart is more detailed than the generic chart developed for other REDSIAM taskforces, but remains easily usable in practice. CONCLUSIONS: This study illustrates the complexity of cancer detection through sole reliance on healthcare databases and the lack of validated algorithms specifically designed for this purpose. Studies that standardize and facilitate validation of these algorithms should be developed and promoted.

[Study of hospitalizations for pneumococcal pneumoniae in Centre region, 2004-2008]. / Étude des séjours pour pneumopathie à Streptococcus pneumoniae entre 2004 et 2008 en région Centre.

BACKGROUND: Streptococcus pneumoniae is a significant cause of morbidity-mortality: leading agent of community-acquired pneumonia and the first cause of death due to infectious diseases in France. Vaccines are available for children and adults, avoiding serious complications. We studied hospitalizations for pneumococcal pneumonia in Centre region in 2004-2008, using the 2004-2008 national hospital discharges database and assessed vaccine coverage of a sample population. METHODS: Hospital discharges with diagnosis of pneumococcal pneumonia were selected, using the corresponding code (J13) in the French Diagnosis-Related Group coding system. We analysed hospitalization and patient data using linkage of the inpatient stays with their anonymous identification number. We analysed hospitalization and patient data: number and length of stay/patient, co-morbid factors and pneumococcal immunisation status. RESULTS: One thousand five hundred and forty-one hospitalisations were found for pneumococcal pneumonia in Centre Region, in 2004-2008. The time pattern showed an annual increase in hospital stays: winter hospitalisations were most frequent. The median age was 58 years, range: 2 months-106 years. The sex ratio M/F of the 1417 distinct inpatients was 1.43. The hospital impact was substantial, with prolonged length of stay (mean=9.9 days), frequent stays in intensive care unit (20%) and high death rate (6%). The vaccine coverage of the population with pneumococcal pneumonia was only 23%. CONCLUSION: Using the national hospital discharges database, this study presents a snapshot of pneumococcal pneumonia in one French region and demonstrates the local major clinical impact, as found in France. It shows that the hospital discharge database is a potential tool for epidemiology despite its possible bias. This type of study could be useful for organizing a regional vaccination campaing due to the better knowledge of the disease.

[Impact of influenza rapid diagnostic tests (IRDT) on the diagnosis of influenza and on the management of influenza in children in ambulatory pediatric setting]. / Impact des tests de diagnostic rapide de la grippe dans la prise en charge des enfants en période d'épidémie en pédiatrie de ville.

OBJECTIVE: Several studies have highlighted the assets of the influenza rapid diagnostic tests (IRDT) for the emergency department management of febrile children. The objective of this study was to determine in ambulatory pediatric setting impact of IRDT on the management of febrile children during an epidemic, especially on other diagnostic testing performed, antibiotic and antiviral treatments. METHODS: During an influenza epidemic, 37 paediatricians in three different areas of France included all children presenting fever with respiratory illnesses; they performed IRDT (test QuickVue for Influenza A and B, Quidel). Data collected were antiflu vaccination, previous asthma, symptoms, clinical signs, other diagnostic testing performed, and a follow-up two weeks later. RESULTS: Between December, 2006 and April, 2007, 695 children entered the program. The average age of those children was 4.1 years old (SD 3.4), median 3.2 (0.07-17.5). In 41.6% of the cases, the tests proved positive. Among 13 symptoms of influenza, only five were significantly more present in the group IRDT+: shiver (68.1% versus 57.4%), asthenia (87% versus 79.9%), cough (87.5% versus 70.1%), rhinorrhea (93.4% versus 83.3%), and sleepiness (54.2% versus 43.4%). The number of laboratory tests and radiographs ordered were less frequent in group IRDT+ than in group IRDT-: respectively 0.7% versus 11.6%, and 0.7% versus 8.6% (p<0.0001). IRDT+ group received antibiotics in 7.6% of cases (22 patients, 20 for OMA) and antiviral in 64.7%. IRDT- group received respectively 18.5% antibiotics, and no antiviral (p<0.0001). CONCLUSION: This study confirms the difficulty of clinical influenza diagnosis, and suggests the assets of IRDT to diagnose influenza and to improve the management of influenza in ambulatory paediatric setting.

[BCG vaccine coverage in private medical practice: First data in children below two years old, seven months after the end of compulsory vaccination in France]. / Couverture vaccinale BCG en médecine libérale : premières données chez le nourrisson, sept mois après la levée de l'obligation vaccinale en France.

OBJECTIVES: In July 2007, compulsory BCG vaccination for all children was replaced by a strong recommendation to vaccinate children at high risk of tuberculosis (children who live in Ile-de-France [IDF] or Guyana regions, who were born or whose parents were born in tuberculosis endemic countries, with a family history of tuberculosis or living in conditions defined as at risk by the doctor). In the absence of tools to detect an early decrease in vaccine coverage (VC) in this specific group, we conducted a survey with the main objective of measuring BCG VC in high risk children for which BCG is now recommended and who were born after the change in BCG vaccine policy. METHODS: Cross-sectional survey performed amongst physicians registered at "Infovac-France", a network of general practitioners and paediatricians particularly aware of recent changes in the field of vaccinations. Each doctor was asked to recruit, during his medical consultation, between six and 12 children aged 2-7 months (born after the end of compulsory BCG vaccination in July 2007) and 8-23 months (born after the withdrawal from the market of the multipuncture form of BCG [Monovax] in January 2006 and before the end of compulsory BCG vaccination in July 2007). Doctors were asked to fill in a structured online questionnaire. Data were standardized and analysed with Stata 9.2. RESULTS: A total of 2536 children, recruited by 279 general practitioners and paediatricians (6.5% of all contacted doctors), were included. VC in the target group of high risk children for who BCG is still recommended and who were seen by doctors working in a private medical practice was: overall 68%; 58% in children born after the end of compulsory BCG vaccination (68% in IDF, 48% outside IDF); 77% in those born after the withdrawal of Monovax from the market and before the end of compulsory BCG vaccination; 90% in children living in IDF born after the end of compulsory vaccination and considered as particularly at risk of tuberculosis (presence of vaccination criteria other than residing in IDF) and 60% in the same category of children whose sole criteria for vaccination was residing in IDF. Of doctors who worked in a private medical practice: 75% used to perform the BCG vaccination themselves and 58% had recommended or suggested vaccination to children at risk who were not yet vaccinated. Seventy-six percent of parents of children at risk of tuberculosis not yet vaccinated accepted BCG vaccination when recommended by their doctor. CONCLUSION: Our survey showed, on the one hand, insufficient VC in children seen in a private medical practice and born after the end of compulsory vaccination for whom BCG is still recommended. This should encourage the Ministry of Health to reinforce its communication concerning this new policy. On the other hand, the survey showed encouraging results concerning both the coverage of children at particularly high risk in IDF and the adherence of doctors and families to the new vaccine policy. These results should be interpreted with caution, taking into account the methodological limitations of this survey.

[Surveillance of Haemophilus Influenzae meningitis in children in France, 2001-2006]. / Surveillance des méningites à Haemophilus Influenzae de l'enfant en France, 2001-2006.

BACKGROUND: The implementation of Haemophilus influenzae b (Hib) vaccination program in France in 1993 resulted in a rapid and dramatic decrease of the Hib meningitis incidence in children. The aim of our study was to describe the residual Haemophilus influenzae (Hi) meningitis in the French paediatric population between 2001 and 2006. METHODS: The French Paediatric Infectious Diseases Group set up an active surveillance network to analyze the clinical and biological features of bacterial meningitis. We used these data to retrospectively study the risk factors, signs and symptoms, vaccination status, cerebrospinal fluid analysis, treatment and case fatality rate of Hi meningitis. RESULTS: Among the 2539 cases of bacterial meningitis reported in France between 2001 and 2006, 69 (2.7 %) were due to Hi. A mean number of 11.5 cases of Hi meningitis was reported annually (minimum 6, maximum 16). Among Hi meningitis cases, 36 strains were of serotype b, 8 were capsulated but not b (6 f, 1 e and 1 unknown serotype), 20 strains were not capsulated, and 5 were non studied. The mean age of the children was 30.3 months (median 13.8 months, range 3.3 months to 14.5 years). 41 % of children with Hib meningitis did not received any anti-Hib vaccine and 41 % did not followed the French recommendations for Hib vaccine. CONCLUSION: Hi meningitis still occurs, and more than half is due to the b serotype. Among Hib cases, 14 % did not recieved any anti-Hib vaccine and 15 % received an incomplete vaccination schedule. Increase of vaccine coverage and use of an earlier booster dose at the age of 12 months could further improve the epidemiology of Hib meningitis. The immunity of children with Hib meningitis should be systematically studied in order to improve the comprehension of the pathophysiology of vaccine failure.

[Listeria monocytogenes meningitis in children in France]. / Méningites à Listeria monocytogenes de l'enfant en France.

UNLABELLED: Listeriosis is a serious invasive disease which affects mainly pregnant women, newborns and immunocompromised adults. OBJECTIVE: To analyze specifically the epidemiological and clinical data of the meningitis due to Listeria monocytogenes (Lm), from the French Network of Surveillance of Bacterial Meningitis in childhood. PATIENTS AND METHODS: Patients were aged 0 to 18 years. The diagnosis was based on a combination of a feverish meningeal syndrome and a positive culture of cerebrospinal fluid (CSF) and/or a positive PCR in the CSF and/or positive blood culture associated with a pleiocytose. RESULTS: Among 2539 cases of bacterial meningitis recorded in 6 years (2001 to 2006), 18 cases were due to Lm (0.7 %) (sex ratio M / F : 0.8). The average of age was 2.5 years (median : 0.5 ; ext : 0-15.1). The serotype of Lm was 4B in half of the cases. Most cases have occured in summer and autumn. Two patients presented an acquired or congenital immunodeficiency. Fifty-six percent (n=10) were younger than 1 year, among them, 7 were newborns. The CSF direct microbiologic investigation was suggestive of Lm (Gram positive bacilli) only in two cases, but the culture of CSF was positive for 16 patients and the blood culture was positive for 2 other patients. Three of 18 patients died between 7 and 13 days after admittance : a premature baby of 25 weeks'gestational age, two full-term newborns of 2 days and 1.5 months old. The mortality rate was 16.7 % before the age of 1 year (no death after this age). CONCLUSION: Meningitis due to Lm remains a rare disease, including in neonatal period. The recent increase of cases in adults requires to maintain vigilance in children especially since direct examination of CSF can rarely allow the diagnosis.

[Evaluation of impact of CRP rapid test in management of febrile children in ambulatory pediatric practice]. / Evaluation de l'impact du test rapide de la CRP en microméthode par des pédiatres de ville prenant en charge des enfants de plus de trois mois avec fièvre isolée.

OBJECTIVE: Fever without source (FWS) is a common cause of children visits to pediatric practices. Clinical evaluation does not always rule out efficiently an invasive bacterial infection. Among blood markers, several publications have suggested the value of C-reactive protein (CRP). This study was performed to assess, in private practices, the impact of rapid CRP test compared to usual technique at the laboratory for the management of children with FWO. MATERIAL AND METHODS: The study was undertaken in 2006-2007, in 14 pediatric practices. Pediatricians had to enroll all children, older than three months, consulting for FWS, for whom CRP was prescribed. The pediatric practices were distributed in two groups: in the first one, pediatricians had rapid CRP tests (NycoCard) CRP test, Progen Biotechnique) and in the second one, they sent children to laboratory for the dosage of CRP as usually. RESULTS: Between October 2006 and June 2007, 227 children were enrolled by 17 pediatricians: 159 in the group with rapid CRP test (group 1), 68 in the group without (group 2). The cost of routine biological tests (micro or macro CRP, blood cell count and urine cultures) was on average lower for group 1 compared to the group 2: respectively 7.7 versus 39.3 euro (P<0.0001), a reduction from approximately 80% of cost. In group 1, more dipstick urine tests (22.6 versus 4.4, P=0.0009), less urine cultures (19.5% versus 67.6% P<0.0001) and blood prescriptions were prescribed (3.8% versus 100%, P<0.0001), pulmonary X-rays were not different (23.9% versus 19.1%, P=0.4). It was not observed difference in antibiotic prescription between the two groups (15.7% group 1 versus 19.1% group 2, p=0.5). The average time to obtain the results examinations in laboratory was approximately 11h (median 4.5h, extremes 45 min to two days), for five min in group 1. In group 1, children management was different according to the CRP levels. During the follow-up, no difference was observed between the two groups except less hospitalizations in group 1 (2.9% versus 15.3%, P=0.0015). CONCLUSION: This study suggests the interest of rapid CRP test for febrile children in ambulatory pediatric practice by reducing number and cost of laboratory examinations and timesaving for patients and practitioners.

[Characteristics of meningococcal meningitis in children in France]. / Caractéristiques des méningites à méningocoque de l'enfant en France.

BACKGROUND: In France, meningococcal meningitis account for 50% of bacterial meningitis in children. The GPIP/ACTIV (Groupe de Pathologie Infectieuse Pédiatrique and Association Clinique et Thérapeutique Infantile du Val de Marne) set up an active surveillance network to analyze the epidemiological, clinical and biological features of meningococcal meningitis. METHODS: From 2001 to 2007, 252 French paediatric wards working with 166 microbiology laboratories enrolled all children (0-18 years old) with bacterial meningitis. Risk factors, signs and symptoms, vaccination status, cerebrospinal fluid analysis, treatments and case fatality rate were recorded. RESULTS: During the period of the study, 1344 meningococcal meningitis were reported among 2951 (45.5%) bacterial meningitis. Mean age was 4.4 years (+/-4.7, median 2.5) and 2/3 cases occurred in children under 5 years (68.5%). Serogroup B (59.1%) was preponderant following by serogroup C (28.9%). 25% of children had received an antibiotic treatment 24hours before lumbar puncture. A shock was reported in 31.3% of cases. Cerebrospinal fluid culture was positive in 73% of cases. All N. meningitidis isolates were susceptible to cefotaxime and ceftriaxone while 41.6% and 25.7% showed reduced susceptibility to penicillin and amoxicillin respectively. Two cases of meningitis due to isolates of serogroups C and B were reported in two children that were respectively vaccinated using A+C plain saccharide vaccine or two doses of MenBvac vaccine. All patients had received beta-lactamin. Global case fatality rate was 6.6% but was higher (9.9%) for serogroup C than for serogroup B (5.5%) (p=0,007). CONCLUSION: This study is among the largest series of microbiologically documented meningococcal meningitis to date (more than 1300 cases). In France, meningococal is responsible for 50 % of meningitis. Effective meningococcal serogroup B vaccine and serogroup C vaccination recommendation could lessen considerably the burden of meningococal meningitis.

Paediatric varicella hospitalisations in France: a nationwide survey.

Paediatric patients hospitalised with varicella (n = 1575) were reported to a French national network between March 2003 and July 2005. Superinfection was identified in 50.3% of cases, principally of skin and soft-tissue (36.5%). The risk of superinfection increased with fever relapse, use of non-steroidal anti-inflammatory drugs, prolonged fever, an age of 1-5 years, and contamination at the childminder's home. Neurological complications were observed in 7.8% of cases, while pulmonary complications were less frequent (3.1%). Forty-nine patients had sequelae and eight patients died. Surveillance should continue in France with a view to the future implementation of a universal vaccination programme.

A review of classification algorithms for EEG-based brain-computer interfaces.

In this paper we review classification algorithms used to design brain-computer interface (BCI) systems based on electroencephalography (EEG). We briefly present the commonly employed algorithms and describe their critical properties. Based on the literature, we compare them in terms of performance and provide guidelines to choose the suitable classification algorithm(s) for a specific BCI.

[Vaccination in parents of young infants survey]. / Enquête sur le statut vaccinal des parents de jeunes nourrissons.

Since 2004, in France, pertussis booster is recommended in parents of young infants and adults likely to become parents. This recommendation adds to others such as rubella vaccination in unvaccinated or seronegative women and decennial dT-IPV booster. The objective of this study is to evaluate the impact of these recommendations in parents of young infants. Pediatricians had to include parents of infants at the first well-baby visit after birth. Vaccination data were secondary recorded from parent's health record or called upon their memory. Between June and October 2006, 41 pediatricians included parents of 400 infants (median age: 36 days). dT-IPV booster was recorded or recalled in 37.4% within the 10 previous years and 17.7% within the 3 previous years. Among this last group, only 11.8% had received a combination including pertussis. Rubella serology was declared as positive by 94% of the mothers, but the physicians obtained the information of a previous rubella vaccination in only 71.7% of the mothers. Among the 9 seronegative mothers during pregnancy, only 3 were vaccinated in postpartum. Adults' immunization guidelines are not well known and poorly applied in France. The unavailability of monovalent pertussis vaccine reduces the eligible population. Two years after the launch of the pertussis cocoon strategy, the coverage of eligible young parents remains low and many opportunities are too frequently missed on the opportunity of decenial dTPolio booster. Rubella catch up strategy should be improved. Adults' vaccination strategies and guidelines need to be better broadcasted to health care professionals and also families.

[Impact of the rapid diagnosis downtown in the assumption of responsibility of the children in period of influenza]. / Impact des tests de diagnostic rapide en ville dans la prise en charge des enfants en période de grippe.

Several studies in children showed at the paediatric emergency hospital the interest of influenza rapid diagnostic tests (IRDT) in this disease for which the clinical diagnosis is difficult in children. The purpose of this prospective study carried out in ambulatory paediatric setting was to evaluate impact of the IRDT in the assumption of responsibility of children suspected of Influenza infection. Thirty paediatricians (14 without IRDT, 16 with IRDT) included 602 children between 2004 and 2005. The influenza was confirmed by IRDT in 54% of the cases. Among the 13 symptoms or signs recorded, only 4 - chills (61.6 vs 48.4%), cough (89.8 vs 71.1%), rhinorrhea (97.9 vs 86.2%), and anorexia (50.3 vs 34.8%) - were significantly more frequent (P

Classification of movement intention by spatially filtered electromagnetic inverse solutions.

We couple standardized low-resolution electromagnetic tomography, an inverse solution for electroencephalography (EEG) and the common spatial pattern, which is here conceived as a data-driven beamformer, to classify the benchmark BCI (brain-computer interface) competition 2003, data set IV. The data set is from an experiment where a subject performed a self-paced left and right finger tapping task. Available for analysis are 314 training trials whereas 100 unlabelled test trials have to be classified. The EEG data from 28 electrodes comprise the recording of the 500 ms before the actual finger movements, hence represent uniquely the left and right finger movement intention. Despite our use of an untrained classifier, and our extraction of only one attribute per class, our method yields accuracy similar to the winners of the competition for this data set. The distinct advantages of the approach presented here are the use of an untrained classifier and the processing speed, which make the method suitable for actual BCI applications. The proposed method is favourable over existing classification methods based on an EEG inverse solution, which rely either on iterative algorithms for single-trial independent component analysis or on trained classifiers.

[Impact of CRP rapid test in management of febrile children in paediatric emergency units of Ile-de-France]. / Impact de la protéine C-réactive (CRP) en microméthode sur la prise en charge des enfants fébriles aux urgences pédiatriques en Ile-de-France.

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.

[Evaluation of the information given to parents during the planned preanaesthetic consultation in a paediatric hospital]. / Evaluation de l'information donnée aux parents en consultation préanesthésique programmée dans un hôpital pédiatrique.

INTRODUCTION: Information given to the parents of paediatric patients during the preanaesthetic consultation (CS) must be understandable. OBJECTIVE: We have studied the impact of this information given during CS. METHODS: Prospective study over four months with a questionnaire completed by parents after CS and before the hospitalization. The Sfar information booklet was given to the parents before CS. The study evaluated whether the information had been given ("have you received the information on...?"), understood ("Did you understand...?"), and if CS had influenced anxiety of parents/child; on four items of information, anesthetic risk, transfusion, postoperative pain, and anesthetic technique. The questionnaire noted also the parents sociocultural level (NSC), and if they had read the Sfar booklet. Statistical analysis (descriptive, uni-, multivariate), p<0.05. RESULTS: Four hundred questionnaires were distributed, 334 were analyzed. The information on the four items was considered to have been given in 75%, understood 72%, and to have diminished anxiety 68%. These results were not influenced by whether or not (88%) parents had read the Sfar booklet. How much information was given was a function of the physician giving the information. Elevated NSC and amount if information given improved comprehension optimized. Diminution of anxiety was when all four items were understood, CS was performed by a senior physician and the parent's NSC was high. DISCUSSION: Information better adapted to NSC may improve the quality of CS. The Sfar booklet does not contribute to parents understanding in this context.

[Value of the Bébé-Vision test in the screening of strabismus and anisometropic amblyopia in infants]. / Intérêt du Bébé-Vision dans le dépistage de masse de l'amblyopie strabique et anisométropique du nourrisson.

PURPOSE: To evaluate the accuracy of the Bébé-Vision test for detecting strabismic, ametropic and anisometropic amblyopia in childhood. METHODS: We screened 199 infants under 20 months of age. The screening consisted of a full orthoptic examination by a trained orthopist (cover test, fixation test), a forced choice preferential looking technique (Bébé-Vision test) prior to cycloplegia to test visual acuity, cycloplegic refraction by retinoscopy, and examination of the fundi. RESULTS: Fifteen infants were abnormal on orthoptic examination (clinical evidence of esotropia and/or limitation of abduction and/or amblyopia). The Bébé-Vision test demonstrated a significant interocular difference on the same side of the suspected amblyopic eye in 3 cases and on the opposite side in 3 cases, and no difference in 9 cases. The monocular Bébé-Vision test was abnormal in 51 cases and there was an abnormal cycloplegic refraction in 33 cases. Statistical analysis of these tests demonstrated a very low sensitivity (42%) and a good specificity (90%) for the Bébé-Vision test in detecting amblyopia related to refractive error. CONCLUSION: The Bébé-Vision test does not reliably reveal strabismic or anisometropic amblyopia and is not recommended as a screening test. Diagnosis should continue to be based mainly on the classical clinical methods.

[Necrotizing enterocolitis and apnoeas-bradycardias of the preterm newborn]. / Entérocolite ulcéro-nécrosante et apnées-bradycardies du nouveau-né prématuré

UNLABELLED: We conducted a case control study during six and a half years with the objective to analyse the risk factors for NEC. POPULATION AND METHODS: All cases of confirmed NEC matched to controls for identical gestational age and period of hospitalization; apnoeas-bradycardias prospectively counted. RESULTS: Forty-five cases were compared to 89 controls. The isolated risk factors were: an intra-uterine growth retardation (OR = 3,65, 95% confidence interval [CI] 95%: 1,54-8,63); a birth weight < 1000 g (OR = 8,16, CI 95%: 1,17-56,62), compared to a weight >/= 1500 g; a triple antibiotherapy (OR = 6,15, CI 95%: 1,16-32,45); an umbilical venous catheterization (OR = 2,64, CI 95%: 1,09-6,44); a number of simple apnoeas-bradycardias >/= 3rd tercile (n = 27) (OR = 4,54, CI 95%: 1,29-15,93), or severe (stimulated or with hypoxia) apnoeas-bradycardias >/= 3rd tercile (n = 8) (OR = 6,15, CI 95%: 1,59-23,75); an haemoglobin level lower than the 1(st) tercile (95 g/L) (OR = 5,90, CI 95%: 1,20-20,13); and milk thickening by Gumilk (OR = 2,78, CI 95%: 1,11-6,90). CONCLUSION: In the present practices, anoxo-ischemic factors during the first week of life do not represent an important risk of NEC; a great vigilance must be exercised for indications of the triple antibiotherapy and the treatment of apnoeas-bradycardias.
