Antimicrobial treatment of ENT infections.

Ear, nose and throat (ENT) or upper respiratory tract infections (URTI) are the most common infections in children and the leading causes of antibiotic prescriptions. In most cases, these infections are due to (or are triggered by) viruses and even when bacterial species are implicated, recovery is usually spontaneous. The first imperative is to refrain from prescribing antibiotics in a large number of URTIs: common cold, most cases of sore throat, laryngitis, congestive otitis, and otitis media with effusion. On the contrary, a decision to treat sore throats with antibiotics is based primarily on the positivity of the Group A Streptococcus (GAS) rapid antigen diagnostic tests. For ear infections, only (a) purulent acute otitis media in children under 2 years of age and (b) complicated or symptomatic forms of purulent acute otitis media (PAOM) in older children should be treated with antibiotics. Amoxicillin is the first-line treatment in the most cases of ambulatory ENT justifying antibiotics. Severe ENT infections (mastoiditis, epiglottitis, retro- and parapharyngeal abscesses, ethmoiditis) are therapeutic emergencies necessitating hospitalization and initial intravenous antibiotic therapy.

Evaluation of daily hydration in pediatric outpatients over 3 years old.

The topic of hydration of children over 3 years of age is often neglected in general pediatric consultations, even though proper hydration is essential for optimal physical and intellectual functions. OBJECTIVE: To evaluate the daily water and beverage consumption of 3- to 8-year-old patients in a private pediatric practice through a retrospective observational study. METHOD: This single-centre study was conducted in a French private practice with five pediatricians and included 200 healthy children, aged 3-8 years. RESULTS: Recommended intake of beverages was reached in 62% of 54 children in the 3- to 4-year-old group and 43% of the 146 children in the 4- to 8-year-old group. Recommended beverages intake of±20% was found in 55% of the 3- to 4-year-old group and 45% of the 4- to 8-year-old group. The potential risk factors of inadequate hydration could not be demonstrated in this study. Water alone was the predominant intake in 63% of the 200 children; milk accounted for 19%, and sweetened drinks for 17%. CONCLUSIONS: These results show a persistent gap between recommended and observed total beverage intake. Although our results are more robust than previous French and international published data, they remain insufficient. In the future, a systematic approach to hydration with parents and children is needed including personalised advice, while maintaining other public health interventions in schools and canteens.

[Use of group A streptococcal rapid diagnostic test in extra-pharyngeal infections]. / Utilisation des tests de diagnostic rapide du streptocoque du groupe A en dehors de l'angine.

The purpose of this study was to assess the performances of the group A streptococcus (GAS) rapid antigen diagnostic tests (RADTs) in extra-pharyngeal infections. Between October 2009 and June 2014, 368 patients (median age: 48 months) were enrolled. The pathologies involved were : 160 perineal infections (44 %), 69 blistering distal dactylitis (19 %), 55 cervical lymphadenitis (15 %), 31 crusty or bleeding rhinitis (8 %), and 53 other diseases (14 %). The sensitivity of GAS-RADT used was 96 % (95 % CI: 92-99 %), the specificity 81 % (95 % CI: 75- 86 %), the negative predictive value 97 % (CI 95 %: 93-99 %), and the positive predictive value 79 % (95 % CI: 73-85 %). Finally, positive and negative likelihood ratio were 5 (95 % CI: 4-7) and 0.05 (95 % CI: 0.02-0.11) respectively. The GAS-RADTs developed for pharyngitis have comparable performances in these settings and therefore can be used.

[Antibiotic resistance of pneumococci and H. influenzae isolated from the nasopharyngeal flora of children with acute otitis media between 2006 and 2010]. / Résistance aux antibiotiques des pneumocoques et H. influenzae isolés de la flore rhinopharyngée d'enfants présentant une otite moyenne aiguë entre 2006 et 2010.

OBJECTIVES: The choice of antibiotics (ATB) to treat acute otitis media (AOM) has to take into account the level of resistance of bacteria species implicated. The aim of this study was to evaluate in France, ATB resistance of pneumococci and H. influenzae isolated from the nasopharyngeal flora, in children with AOM, vaccinated with 7 valent pneumococcal conjugate vaccine (PCV7). METHODS: From 2006 to 2010, 66 pediatricians performed nasopharyngeal specimens of children 6 to 24 months with AOM. Demographic characteristics, history, vaccination status and symptoms were reported on a case report form transmitted to ACTIV. RESULTS: Of the 3,501 children included (mean age 13.5 ± 5 months), over 98% were PCV7 vaccinated and 41.1% were cared in day care center. A total of 47.3% of children had received ATB within 3 months before inclusion (cephalosporins, 22.6% and amoxicillin clavulanate, 19.2%). Pneumococcus and H. influenzae carriage was respectively 57.9% and 48.2%. Pneumococcal strains with reduced susceptibility to penicillin represented 46.3% of cases (3.9% highly resistant strains and 42.4% intermediate resistant strains). Factors that increased the risk of carrying these strains were: day care center (OR: 1.5, 95% CI: [1.2, 1.9]) and two courses or more of ATB before inclusion (OR: 2.6 (95% CI: [2.0, 3.4]). For H. influenzae strains the proportion of ßlactamases+ producing strains was 17.1% and those with reduced susceptibility due to penicillin binding protein changes (BLNAR+ strains+) accounted for 7.7% of cases. Three factors increased the risk of carriage BLNAR+ ßlactamase+ producing strains: age equal or greater than 12 months (OR: 3.5, 95% CI: [1.2, 10.3]), cephalosporin use (OR: 2.5, 95% CI: [1.0, 6.1]) and two courses or more of ATB before inclusion (OR: 3.1, 95% CI: [1.2, 8.0]). CONCLUSION: The data in this study (reduction of ßlactamase producing H. influenzae strains and increase of intermediate penicillin pneumococcal strains) should help to change the choice of antibiotics for AOM in children in France, by reducing the role of oral cephalosporins and secondly, by giving frontline amoxicillin ± clavulanic acid.

[Acute otitis media in ambulatory practice: epidemiological and clinical characteristics after 7 valent pneumococcal conjugate vaccine (PCV7) implementation]. / Otite moyenne aiguë en pédiatrie ambulatoire : caractéristiques épidémiologiques et cliniques après l'introduction du vaccin antipneumococcique conjugué 7 valent (PCV7).

BACKGROUND: In US, pneumococcal conjugate vaccine (PCV7) had reduced the burden of AOM and changed the profile of the disease. Prior to PCV7 implementation in France, AOM represented 8% of pediatricians visits and failure rate was 12%. The aim of this study is to describe the epidemiologic characteristics of AOM after PCV7 implementation. METHODS: From 2007 to 2008, 30 pediatricians enrolled 3141 patients 3 to 36 months old with AOM. Standardized history and physical examination findings were recorded. Factors related to AOM failures were identified by multivariate logistic regression. RESULTS: AOM accounted for 5.8% of the 43 433 visits or 6.2 cases/week per pediatrician. Among 3141 evaluable AOM cases (mean age 16.7±8 months, peak incidence at 10 months), 99% had been vaccinated with PCV7 and 42.1% attended day care (DCC). Recurrent AOM comprised 24.5% of cases and 51% of children had received ATB in the last 3 months. At the time of diagnosis, 47.1% had fever≥38,5°C, 74.5% otalgia and 4.7% otorrhea. Febrile and painful AOM accounted for 29.5% of cases and cunjunctivitis-otitis syndrome for 18.2%. ATB was prescribed in 98.7% of cases (cefpodoxime proxetil, 59% and amoxicillin/clavulanate, 37%). The failure rate was 6.4% and failure risk was greater in children in DCC (OR=1.50, [1.10;2.05]), young age<18 months (OR=1.47, [1.06;2.04]) and history of recurrent AOM (OR=1.45, [1.02;2.06]). CONCLUSION: Despite PCV7 implementation, AOM remains a very frequent childhood infection and a major reason for ATB prescriptions.

[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.

[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.

[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

[Rehabilitation of children with chronic inflammatory arthritis]. / Rééducation de l'enfant atteint d'arthrite inflammatoire chronique.

All children with chronic arthritis require rehabilitation. Indications of the various techniques are mainly dependent upon the stage of the disease. The choice of the most appropriate technique (preservation of articular mobility, preservation of the muscular strength, orthoses) are based on an accurate assessment of each joint and on imaging. Specific measures are indicated for each localisation. The handicaps resulting from the disease and from its treatments (corticosteroids) should be reduced by adequate information of the family, adaptation of the living environment, and technical helps.

[Regressive myelodysplastic syndromes in children. Committee on Childhood Myelodysplasia of the Society of Pediatric Hematology and Immunology]. / Myélodysplasies régressives de l'enfant. Groupe de Travail sur les Myélodysplasies de l'Enfant de la Société d'Hématologie et d'Immunologie Pédiatrique (SHIP).

BACKGROUND: As in adults, myelodysplastic syndromes in children are often preleukemic and their spontaneous remission is exceptional. CASE REPORTS: Case 1. A girl, aged 8 years, developed pancytopenia with macrocytic anemia. The myelogram and bone marrow biopsy showed dyserythropoiesis with macroblastosis, but without sideroblasts. The chromosome configuration was normal and the negative results of other investigations led to the diagnosis of refractory anemia without any known cause. Bone marrow transplantation was considered, but a spontaneous remission intervened and has persisted for 3 years. Case 2. A girl, aged 5 years, was investigated for worsening of a macrocytic anemia that had been present for 3 years, without changes of granulocytes and platelets. The myelogram showed dyserythropoiesis with megaloblastosis and sideroblasts. No known cause could be identified. As for the preceding patient, a spontaneous remission occurred, and has persisted for 3 years. Case 3. A girl, aged 5 months, developed pancytopenia. The myelogram showed dys-megakaryocytopoiesis. All hematologic data spontaneously normalized after 1 year, and have remained so 1 year later. CONCLUSION: The spontaneous remission, that has occurred in our 3 patients, has been reported in one only adult. This possibility precludes considering all the myelodysplastic syndrome in children as preleukemic, and suggests that bone marrow transplantation is not urgent in these situations.

[Idiopathic laryngotracheobronchial calcifications in children. Apropos of 2 cases]. / Les calcifications laryngo-trachéo-bronchiques idiopathiques chez l'enfant. A propos de deux observations.

Calcifications of cartilage in the larynx, trachea and bronchi are rare in children. Two cases reported and listed with 5 similar cases of the literature. Such calcifications are generally discovered in young children and congenital stridor is commonly associated with. Calcifications of bronchi are not present in every case. The blood calcium is normal. Laryngoscopic examination shows in two cases a laryngeal stiffness. The prognosis is good. In two cases, one of the parents of under 40 years old, also had calcifications of the trachea and of the bronchi.

[Paroxysmal nocturnal hemoglobinuria and aplastic anemia]. / Hémoglobinurie paroxystique nocturne et aplasie médullaire.

The case of a 14 year-old adolescent girl presenting with paroxysmal nocturnal hemoglobinuria (PNH) associated with aplastic anemia is reported. This disease, rare in children, is characterized by an acquired hemolytic anemia, with abnormal sensitivity to complement: PNH actually affects the bone marrow stem cell. This explains its possible association with any type of malignant blood disease and with aplastic anemia. When aplastic anemia is the first sign of the disease, diagnosis is delayed, due to the possible negative response of the specific Ham's test. Therefore, the proper complications of PNH, especially thromboses, may be misappreciated and poorly managed.
