[ECOVIR: Study of a primary care cohort in of patients with Acute Respiratory Infections in Normandy, an example of pluri-professional hospital-primary care coordination]. / ECOVIR : mise en place d'une cohorte en soins primaires, un exemple de coopération pluri-professionnelle ville-hôpital.

Acute Respiratory Infections (ARI) need be better understood and more effectively treated, especially insofar as they are of pivotal importance in public health, particularly during a crisis such as the SARS-CoV2 pandemic. The prospective, multicentric cohort study of viral codetections in respiratory samples study known as ECOVIR was conducted in Normandy, France during two winters (2018-2019, 2019-2020). The objective of the project was to create a biobank of respiratory tract samples from patients consulting their general practitioner (GP) for ARI symptoms. ECOVIR involved 36 GP investigators (GPI), from 8 health care centers throughout Normandy. Six hundred and eighty-five patients with ARI symptoms were included; naso-pharyngeal samples were taken by the GPIs and subsequently analyzed in virology laboratories for the purposes of viral codetection. The median of inclusions was 16 patients for each of the 31 actively participating GPIs over the two winters (CI25-75% [4.75; 27]). By D7, 92% of the patients contacted had responded to our call for participation, enabling us to obtain clinical, environmental and socio-demographic data. Through this study, we created an original functional network, thereby establishing a viable link between research and primary care, which is generally underrepresented in research protocols, even though it constitutes the cornerstone of the French health care system, especially during this prolonged period of sanitary crisis.

[Increase in asthma prevalence among young children in France]. / Augmentation de la prévalence de l'asthme chez le jeune enfant en France.

INTRODUCTION: Few data on change over time of asthma prevalence in French children are available. METHODS: Data from the 2012-2013 national health survey of schoolchildren conducted in a random sample of almost 20,000 children in the last year of nursery school were compared to those which had been collected in 2005-2006 in the same grade level using the same methodology. RESULTS: In the 2012-2013 survey, children had a lifetime prevalence of asthma of 11.0% with 11.8% reporting wheezing in the preceding year. Asthma was more frequent and more often uncontrolled in children from families with low socioeconomic status. Compared to the survey conducted in the same grade level in 2005-2006, the prevalence ratios adjusted for children's gender and obesity, family structure, parental unemployment and region were 1.13 [1.05-1.21] for lifetime asthma and 1.12 [1.05-1.17] for past-year wheezing. CONCLUSION: In France, the prevalence of asthma in young children increased between 2005 and 2012. The socioeconomic status of children's parents affects both asthma prevalence and control.

[Respiratory syncytial virus (RSV) infections in the pediatric teaching hospital Charles de Gaulle of Ouagadougou, Burkina Faso]. / Infections à virus respiratoire syncytial (VRS) au CHU pédiatrique Charles de Gaulle de Ouagadougou, Burkina Faso.

Human respiratory syncytial virus (RSV) infections are little known in Burkina Faso. The objective of our work is to study the epidemiological and clinical aspects of RSV infections in infants in the Pediatric Teaching Hospital Charles de Gaulle of Ouagadougou. Between July 1(st) 2010 and June 30(th) 2011, we analyzed by direct immunofluorescence and PCR nasopharyngeal swabs from children from 0 to 36 months old. All in all, 210 patients among whom 74 from the external consultation (35.2%) and 136 hospitalized (64.7%) benefited from a nasopharyngeal aspiration. The motives for consultation were cough (91.7%), rhinitis (79.2%), fever (79.2%) and respiratory distress syndrome (66.7%). The evoked diagnoses were predominantly the acute bronchiolitis in 14 cases (58.3%) followed by the acute pulmonary disease in 7 patients (26.2%) then flue in 1 patient (16.7%). We detected by direct immunofluorescence the antigens of the respiratory viruses in 21 nasopharyngeal aspirations with 10 cases of respiratory syncytial virus (RSV) infections (47.6%). The PCR realized on 208 samples allowed to identify 153 positive samples (73.2%) with 24 RSV, i.e. a global prevalence of 16.1% with a peak of 18 cases (75%). In October, all the patients benefited from an often multiple antibiotic treatment of at least 10 days which was not still necessary. The evolution was favorable for all patients. This study confirms the important place of the viruses which are detected in 70% of the cases. The PCR multiplex, certainly expensive but effective and successful, deserves to be used in our developing countries to avoid the irrational prescription of antibiotic.

[New therapies for cystic fibrosis targeting the CFTR gene or the CFTR protein]. / Nouvelles thérapeutiques de la mucoviscidose ciblant le gène ou la protéine CFTR.

BACKGROUND: The treatment of cystic fibrosis has been symptom-based for a number of years. New therapies that aim to improve CFTR protein function are now emerging. CURRENT SCIENTIFIC KNOWLEDGE: The results of gene therapy has been modest but a recent clinical trial shows a positive effect on FEV1. Recent research has focused primarily on CFTR protein function. Significant respiratory improvement (an average 10% FEV1 increase and a decrease in the frequency of exacerbations) has been achieved with ivacaftor, a CFTR potentiator, in patients with gating mutations, resulting in its marketing authorization (in 2012 for the G551D mutation and in 2015 for rarer mutations). In phe508del homozygous patients, the combination of ivacaftor with a CFTR corrector (lumacaftor) has also led to respiratory improvement, albeit less impressive. The effectiveness of ataluren in patients with nonsense mutations is being evaluated. OUTLOOK: New CFTR correctors and potentiators are being developed. CFTR protein therapy could change the course of the disease but cost/effectiveness issues should not be overlooked. CONCLUSION: Ivacaftor can be prescribed in CF patients with a class 3 mutation from the age of 6 years. The Orkambi® will soon be available for homozygous phe508del patients from the age of 12 years.

[Infections in cystic fibrosis: Up-to-date]. / Actualités en infectiologie dans la mucoviscidose.

This review focused on the news in CF airways infection. International guidelines were provided for the care of non tuberculous mycobacteria, and recent studies stressed on the benefit effect of azithromycin or combined antibiotics. The identification of multiresistant environmental bacteria in airways made to account for little-known consequences. Early diagnosis and eradication of Pseudomonas aeruginosa and Staphylococcus aureus methi-R were still a concern, and reports were proposed. However, the studies on staphylococcus methi-R should be interpreted as regards the European or American continent. Thus, levofloxacine has demonstrated its efficacy without enhancing the efficiency. This drug will increase the choice for treating the patient, but no study were provided on the expected modification of the patient microbiota and the known risk of emergent resistance to antibiotics. Lastly, this review underlined that the CF practitioner was encouraged to search and not underestimate the presence of fungus, of which the not so well studied Aspergillus fumigatus.

[New therapeutic developments in cystic fibrosis]. / Nouvelles thérapeutiques ciblant le canal chlorure dans la mucoviscidose.

Since the discovery of chloride secretion by the Cystic Fibrosis Transport regulator CFTR in 1983, and CFTR gene in 1989, knowledge about CFTR synthesis, maturation, intracellular transfer and function has dramatically expanded. These discoveries have led to the distribution of CF mutations into 6 classes with different pathophysiological mechanisms. In this article we will explore the state of art on CFTR synthesis and its chloride secretion function. We will then explore the consequences of the 6 classes of mutations on CFTR protein function and we will describe the new therapeutic developments aiming at correcting these defects.

[Acute viral bronchiolitis: a national study in pediatric emergency departments]. / Bronchiolite aiguë du nourrisson : enquête nationale dans les services d'accueil des urgences pédiatriques.

UNLABELLED: The 2000 French guidelines for acute viral bronchiolitis management underlined clinical criteria for hospitalization. We aimed to assess the impact of these guidelines on admission rates in pediatric emergency departments. METHODS: A prospective multicentric observational study was conducted over 24h in 66 pediatric emergency departments. Questions were asked about the structure, the course of care, clinical data, resource utilization, and hospitalization or discharge of every patient under 2 years of age with acute viral bronchiolitis. An open-ended question allowed clinicians to explain the reason for hospitalization. Multivariable logistic regression analyses were performed to identify independent risk factors for severe disease to assess potential clinical factors associated with hospitalization. Responses were compared using the Student t-test and the Chi(2) test. RESULTS: Of 338 patients enrolled, 145 (45.1%) were admitted. Clinical criteria were associated with hospitalization: clinical deterioration (OR: 3 [95% CI: 1.0-8.5], p=0.04), respiratory rate more than 60/min (OR: 3.4 [95% CI: 1.3-8.8], p=0.02), age under 6 weeks (OR: 29.8 [95% CI: 7.0-125.4], p<0.001), oxygen saturation less than 94% (OR: 15.8 [95% CI: 4.2-60.1], p<0.001), food intake less than 50% of the usual intake (OR: 4.9 [95% CI: 2.2-10.9], p<0.001), and age between 6 weeks and 3 months (OR: 3.2 [95% CI: 1.4-7.2], p=0.007). CONCLUSION: The clinical criteria of the 2000 French guidelines influence hospitalization for acute viral bronchiolitis in pediatric emergency departments. However, other criteria are cited in about one-third of the patients.

[Recommendations for the use of diagnostic testing in low respiratory infections in children older than three months]. / Recommandations sur l'utilisation des nouveaux outils diagnostiques étiologiques des infections respiratoires basses de l'enfant de plus de trois mois.

Recommendations for the use of diagnostic testing in low respiratory infection in children older than 3 months were produced by the Groupe de Recherche sur les Avancées en Pneumo-Pédiatrie (GRAPP) under the auspices of the French Paediatric Pulmonology and Allergology Society (SP(2)A). The Haute Autorité de santé (HAS) methodology, based on formalized consensus, was used. A first panel of experts analyzed the English and French literature to provide a second panel of experts with recommendations to validate. Only the recommendations are presented here, but the full text is available on the SP(2)A website.

Urinary tract infections in hospital pediatrics: many previous antibiotherapy and antibiotics resistance, including fluoroquinolones.

OBJECTIVE: We studied antibiotic resistance in pediatric UTIs and we evaluated the impact of antibiotic exposure in the previous 12 months, very little French data being available for this population. METHODS: We conducted a multicenter prospective study including children consulting for, or admitted in 2 hospitals. Prior antibiotic exposure was documented from their health record. RESULTS: One hundred and ten patients (73 girls), 11 days to 12 years of age, were included in 10 months. Ninety-six percent presented with pyelonephritis, associated to uropathy for 25%. Escherichia coli was predominant (78%), followed by Proteus spp. and Enterococcus spp. The antibiotic resistance rate of E. coli was high and close to that reported for adults with complicated UTIs: amoxicillin 60%, amoxicillin-clavulanate 35%, cefotaxim 5%, trimethoprim-sulfametoxazole 26%, nalidixic acid 9%, ciprofloxacin 7%, gentamycin 1%, nitrofurantoin and fosfomycin 0%. The antibiotic exposure in the previous 12 months involved 62 children (56%) most frequently with ß-lactams (89%) for a respiratory tract infection (56%). A clear relationship between exposure and resistance was observed for amoxicillin (71% vs. 46%), first generation (65% vs. 46%) and third generation (9% vs. 3%) cephalosporins, or trimethoprim-sulfamethoxazole (36% vs. 15%). However, antibiotic exposure could not account alone for the results, as suggested by the 7% of ciprofloxacin resistance, observed without any identified previous treatment. CONCLUSION: Bacterial species and antibiotic resistance level in children are similar to those reported for adults. Antibiotic exposure in the previous 12 months increases the risk of resistance but other factors are involved (previous antibiotic therapies and fecal-oral or mother-to-child transmission).

[Adolescents consulting at the pediatric emergency room for psychological or psychiatric reasons]. / Accueil en urgence des adolescents pour motif pédopsychiatrique.

INTRODUCTION: The number of pediatric emergency consultations for psychological or psychiatric reasons continues to rise, raising the question of the adequacy of existing facilities. Our aim was therefore to identify and characterize a population of adolescents consulting at the pediatric emergency unit at Rouen university hospital. METHODS: This study was conducted from 1 January to 31 December 2006. We distinguished three types of variables in adolescents consulting at the pediatric emergency unit. The main objective was to describe the profile and requirements of these young patients and their subsequent care management as compared to that of other studies. RESULTS: Of the 400 patients consulting over 12years of age, 69% were female and the average age was 13.8years. These cases were mainly attempted suicide in girls and conduct disorder in boys; hospitalization was at the request of the family. These consultations were directly linked to the school calendar and 70% required hospitalization. DISCUSSION: We both analyzed and compared the results of this study to those of other studies to propose solutions to improve the care of these young patients.

[Recommendations for pediatric oxygen therapy in acute and chronic settings: Needs assessment, implementation criteria, prescription practices and follow-up]. / Recommandations pour l'oxygénothérapie chez l'enfant en situations aiguës et chroniques : évaluation du besoin, critères de mise en route, modalités de prescriptions et de surveillance.

Recommendations for acute and long-term oxygen therapy (needs assessment, implementation criteria, prescription practices, and follow-up) in children were produced by the Groupe de Recherche sur les Avancées en Pneumo-Pédiatrie (GRAPP) under the auspices of the French Paediatric Pulmonology and Allergology Society (SP2A). The Haute Autorité de Santé (HAS) methodology, based on the Formalized Consensus, was used. A first panel of experts analyzed the English and French literature to provide a second panel of experts with recommendations to validate. Only the recommendations are presented here, but the full text (arguments+recommendations) is available at the website of the French Paediatric Society: www.sfpediatrie.com.

Treatment of scabies with oral ivermectin in 15 infants: a retrospective study on tolerance and efficacy.

BACKGROUND: The incidence of scabies is increasing in Europe, and it often affects children and infants. Although numerous topical treatments have been approved for treatment of scabies in adults, they are often poorly tolerated in infants. One treatment, ivermectin, remains off label for infants weighing < 15 kg. OBJECTIVES: To report our experience on the safety and efficacy of oral ivermectin in refractory scabies in infants. METHODS: A retrospective study was performed in the dermatology and paediatrics departments of Rouen University Hospital between January 2009 and October 2012. Infants diagnosed with scabies were identified, and the data for those fulfilling the inclusion criteria were analysed. RESULTS: Of 219 infants identified, 15 had received oral ivermectin and had been followed up for at least 3 months. All 15 patients were given two doses of ivermectin, 200 µg kg(-1), at baseline and 14 days later. Of 14 patients contacted 1 month after treatment, 12 had achieved healing. The other two were treated with ivermectin or benzyl benzoate; both healed. Overall, 3 months after the first ivermectin treatment, 13/14 patients had healed and only one had active disease. CONCLUSIONS: Ivermectin is generally well tolerated in infants. The 80% rate of healing observed in infants who had failed to respond to at least two other topical treatments suggests that ivermectin could be considered for treatment of infants with recalcitrant or relapsing scabies.

[Admissions for pediatric asthma in France]. / Les hospitalisations pour asthme chez l'enfant en France, 2002-2010.

INTRODUCTION: Most hospital admissions for asthma exacerbation are avoidable with adequate disease management. The objective of this study was to describe admissions for asthma in children in France using data from the French nationwide hospital database. METHODS: We selected admissions having either a main diagnosis of asthma or a main diagnosis of acute respiratory failure (ARF) with asthma as an associated diagnosis, occurring in children (age<15years) between 2002 and 2010 in France (excluding French Guyana). RESULTS: In 2010, 35,004 asthma admissions and 1381 cases of asthma-related ARF were recorded (crude admission rate, 30.1/10,000 children); the mean length of stay was 2days. The in-hospital lethality rate ranged from 0.01% to 0.03% depending on the year. The annual age-standardized admission rate increased between 2002 and 2010 (+2.5% per year on average in metropolitan France). In 2010, 11.8% of children admitted for asthma or asthma-related ARF were readmitted for asthma or asthma-related ARF at least once within the same calendar year, and 1.3% were readmitted within the week following admission. The proportion of children aged less than 5 years who were readmitted within the same calendar year increased between 2002 and 2010. CONCLUSION: The increase in admission and readmission rates indicates non-optimal management of asthma in children in France.

A retrospective review of factors associated with vasovasostomies in United States military members.

BACKGROUND: Men seeking a vasectomy should receive counseling prior to the procedure that includes discussion of later seeking a reversal. We sought to determine demographic factors that may predispose patients to possibly later seek a vasectomy reversal. METHODS: All U.S. Military electronic health records were searched between 2000 and 2009 for either a vasectomy or vasovasostomy procedure code. Aggregate demographic information was collected and statistical analysis performed. RESULT: A total of 82,945 patients had a vasectomy of which 4,485 had a vasovasostomy resulting in a vasovasostomy-to-vasectomy rate of 5.04%. The average age at vasovasostomy was 34.9±5.0, with an average interval of 4.1±2.2 years. Men undergoing a vasectomy at a younger age were more likely to have a vasovasostomy. Various religions did have statistically significant differences. Within ethnic groups, only Native Americans [OR=1.39 (95% CI 1.198-1.614)] and Asians [OR=0.501 (95% CI 0.364-0.690)] had statistically significant differences when compared to Caucasians. Men with more children at the time of vasectomy were more likely to have a vasovasostomy. CONCLUSION: Younger men, Native Americans, and men with more children at vasectomy were more likely to undergo a vasovasostomy. The reason for these differences is unknown, but this information may assist during pre-vasectomy counseling.

[Isolated intracranial hypertension as the presenting sign of Lyme disease]. / Hypertension intracrânienne isolée révélatrice d'une maladie de Lyme.

We report the case of an eight-year-old patient referred by his primary care physician for chronic headache. Bilateral papilledema was observed along with right sixth cranial nerve palsy, leading to the diagnosis of intracranial hypertension. Head CT showed no mass lesion. Lyme serology was positive by both Elisa and Western blot. Anti-Borrelia antibodies were positive in the cerebrospinal fluid, with intrathecal synthesis confirming neuroborreliosis. Clinical response to ceftriaxone and acetazolamide was favorable. Intracranial hypertension is rarely caused by Lyme disease. Ophthalmologists should be aware of this clinical presentation, since the presenting clinical signs may be purely ophthalmologic. In addition, early diagnosis may avoid optic nerve atrophy or disease spread.
