Impact of the 13-valent pneumococcal conjugate vaccine on the incidence of pneumococcal meningitis in children.

The impact of the 13-valent pneumococcal conjugate vaccine (PCV13) on the incidence of pneumococcal meningitis (PM) in children is unknown. To determine this impact, a descriptive multicentre retrospective cohort study was conducted from 2008 to 2013 in northern France. All laboratory-confirmed PM in children aged <18 years in all hospitals of the area with paediatric units were included. Two independent databases were used for exhaustive identification of cases: medical plus laboratory records at each hospital and discharge codes. The corrected incidence of PM was determined by a capture-recapture analysis using these two databases. Sixty-two cases were found over the 6-year period. A decrease of the PM corrected incidence was observed in the global population (P = 0·07), significant only for children aged <2 years, from 11·9/100 000 in 2008 in 1·9/100 000 in 2013 [6·4 fold-decrease, 95% confidence interval (CI) 1·4-41, P = 0·01] between years 2008 and 2013. When comparing the pre- and post-PCV13 periods, this decrease was still statistically significant for children aged <2 years [7·32/100 000 (95% CI 4·39-10·25) to 2·78/100 000 (95% CI 0·96-4·60), P = 0·01]. Only three (5%) cases of PM caused by vaccine serotypes could have been prevented. After the introduction of the PCV13 vaccine, a decrease in the incidence of PM cases in children in northern France was observed.

Early impact of 13-valent pneumococcal conjugate vaccine on community-acquired pneumonia in children.

BACKGROUND: Pneumococcal serotypes 1, 3, 5, 7F, and 19A were the most implicated in community-acquired pneumonia (CAP) after implementation of 7-valent pneumococcal conjugate vaccine (PCV7). In France, the switch from PCV7 to 13-valent pneumococcal conjugate vaccine (PCV13) occurred in June 2010. An active surveillance network was set up to analyze the impact of PCV13 on CAP. METHODS: An observational prospective study performed in 8 pediatric emergency departments from June 2009 to May 2012 included all children between 1 month and 15 years of age with chest radiography-confirmed pneumonia. Three 1-year periods were defined: pre-PCV13, transitional, and post-PCV13. RESULTS: During the 3-year study period, among the 953 274 pediatric emergency visits, 5645 children with CAP were included. CAP with pleural effusion and documented pneumococcal CAP were diagnosed in 365 and 136 patients, respectively. Despite an increase (4.5%) in number of pediatric emergency visits, cases of CAP decreased by 16% (2060 to 1725) between pre- and post-PCV13 periods. The decrease reached 32% in infants in the same periods (757 to 516; P < .001). Between pre- and post-PCV13 periods, the proportion of CAP patients with a C-reactive protein level >120 mg/dL decreased from 41.3% to 29.7% (P < .001), the number of pleural effusion cases decreased by 53% (167 to 79; P < .001) and the number of pneumococcal CAP cases decreased by 63% (64 to 24; P = .002). The number of additional PCV13 serotypes identified decreased by 74% (27 to 7). CONCLUSIONS: Our data suggest a strong impact of PCV13 on CAP, pleural effusion, and documented pneumococcal pneumonia, particularly cases due to PCV13 serotypes.

Survey of hospital procedures for parapneumonic effusion in children highlights need for standardised management.

AIM: This study sought to evaluate the initial management of children with parapneumonic effusion admitted to all French university hospitals. METHODS: A nationwide survey of all 35 university hospitals took place in 2011 to assess practices for children with parapneumonic effusion, using a hypothetical clinical vignette and a standardised questionnaire. Two to four paediatricians per hospital were interviewed and asked about their initial management, probabilistic antibiotic therapy and its adaptation to microbiological results and subsequent course. Answers from paediatricians working in emergency departments, intensive care units and conventional paediatric units were compared. RESULTS: Of the 100 paediatricians contacted, 95 responded. Of these, 98% would order an initial blood test, 70% would order diagnostic thoracentesis, and all would start immediate antibiotic therapy: 31% with a single drug, 67% with two drugs and 2% with three drugs. The most frequent initial choices were third-generation cephalosporin alone (17%) or combined with rifampicin (34%) or vancomycin (24%). Adaptation varied according to drug used, dose and duration, especially when the microorganism was not Streptococcus pneumoniae. Practices did not differ significantly among the different groups of paediatricians. CONCLUSION: Standardised management of parapneumonic effusion, including routine thoracentesis and more consistent prescription of antibiotics, is needed.

Vaccination of teenagers in France over a 10-year period (2012-2021).

OBJECTIVES: The objectives were to assess trends over the past 10 years in vaccination coverage rates (VCR) among adolescents in France aged 14-15 years, factors influencing decisions to vaccinate, and mothers' opinions on adolescent vaccination. PATIENTS AND METHODS: The 'Vaccinoscopie' internet survey is completed each year by mothers of adolescents, with questions about vaccinations received by their children, and their attitudes and barriers to vaccination. The 2012 to 2021 surveys were analyzed in this study, including data from 1500 adolescents in 2012 and 1000 adolescents each year from 2013 to 2021. RESULTS: None of the adolescent VCR targets were met, despite significant increases since 2012 for vaccines with the lowest coverage rates and vaccines with high but insufficient coverage i.e., meningococcal C (28.7% to 60.8%), HPV in girls (14.2% to 40.8%), hepatitis B (31.6% to 47.3%) and pertussis (76.3% to 91.0%). Physicians remained the primary source of vaccination information for 90.4% of mothers, and their advice had a real impact on improving VCRs. Adolescents were increasingly involved (40.1%) in decisions about vaccination. Depending on the vaccine, over 80% of mothers currently consider adolescent vaccination as useful or essential. Since 2017, they also feel better informed. CONCLUSIONS: Low and under-target VCRs put adolescents at risk of severe disease, and do not enable herd immunity or reduced transmission to other vulnerable age groups to be accomplished. Healthcare professionals must take every opportunity to check adolescents' vaccination status and recommend catch-up vaccines where applicable. Vaccination in schools should be considered.

Pediatric private practice in the Nord-Pas-de-Calais region: Demographics, organization, and challenges.

While the needs for pediatric care are increasing and becoming more diverse, pediatric private practice in France is encountering difficulties linked to a growing medical demographic deficit. The objective of this study was to give an overview of pediatric private practice in the Nord-Pas-de-Calais region and to describe the main challenges encountered. METHODS: For this descriptive observational survey, private practice pediatricians in the Nord-Pas-de-Calais region filled out an online questionnaire between April 2019 and October 2020. RESULTS: The response rate was 64%. Most respondents practiced in an urban area (87%) and shared the practice with other physicians (59%). A majority (85%) had previously worked in hospital; 65% reported training in a subspecialty. Overall, 48% had other professional activities; 28% worked night shifts and 96% accepted urgent requests for consultations. A total of 33% reported having difficulties contacting specialists for consults, and 46% had difficulties in obtaining written reports of their patients' hospitalizations. All respondents participated in a form of ongoing medical education. The main difficulties were: lack of information about how to found a private practice (68%), lack of personal time (61%), balance between medical and administrative work (59%), and an excess of patients to care for (57%). The main satisfactions were: trusting relationships with patients (98%), freedom in their choice of practice (85%), and the diversity of problems and situations encountered (68%). CONCLUSION: Our study underlines that private practice pediatricians are involved in healthcare provision, in particular regarding ongoing medical training, subspecialties, and continuity of care. It also highlights the problems encountered and the possible improvements: developing better communication between private practice and hospitals, reinforcing training during residency, and highlighting the importance and complementarity of private practice in children's healthcare.

[Should French pregnant women be vaccinated against pertussis during pregnancy?] / Faut-il vacciner les femmes enceintes françaises contre la coqueluche ?

Many countries with a high perinatal level have started a policy of vaccination of pregnant women against pertussis. To date, France has not chosen this policy. The objective was to review knowledge on pertussis mortality in infants. Compare the strategies available to protect the infant before his first vaccination, scheduled for two months of age. We proceeded to a litterature analysis, from January 1998 to 2021. Search by the following keywords used ; "Whooping cough, vaccination, pregnancy, strategy, cocooning", on the scientific basis of "Pubmed", as well as French and foreign vaccination recommendations. Currently 90% of whooping cough deaths are concerning infants under six months of age and this mortality represents 2% of mortality in the first year of life. Vaccination at birth is not effective. The cocooning strategy, which consists of vaccinating those around the child, is expensive and difficult to implement. A systematic vaccination policy for pregnant women is effective and reasonably expensive when compared to the cocooning strategy. In England, it was recently accompanied by a 78% reduction in confirmed cases of pertussis in infants under six months of age. In conclusion, compared to cocooning strategy, pertussis vaccination of pregnant women appears more effective and cost-effective, and this with each pregnancy.

Changes in pediatric emergency department visits during a COVID-19 lockdown period: An exhaustive single-center analysis.

BACKGROUND: In many countries, the restrictions related to the first period of lockdown during the coronavirus disease 2019 (COVID-19) pandemic led to widespread changes in health service usage in general and in emergency departments in particular. However, no comprehensive evaluation of changes has been published to date. The objective of the present study was to determine the precise impact of the 2020 lockdown on admissions to a pediatric emergency department (PED) compared to the same periods in 2018 and 2019. METHODS: This retrospective, observational study included all patients under the age of 183 months (15.25 years) admitted to our French university hospital's PED during the period from March 17 to May 11 in the years 2018, 2019, and 2020. The primary outcome was the change in PED admissions in 2020 compared to 2018 and 2019. The secondary outcomes were notably changes in the primary discharge diagnoses, the discharge destination, and unwarranted visits. RESULTS: A total of 10,479 PED visits were identified, of which 10,295 were analyzed. In 2020, the number of PED visits fell by 61% and 63% vs. 2018 and 2019, respectively. Although the number of discharges to other hospital departments decreased by 52% and 49%, the proportion of these discharges increased: 18% of 1579 in 2020 vs. 13% of 4232 in 2018 and of 4484 in 2019 (p<0.01). Discharge from the PED to the intensive care unit was significantly more frequent in 2020 (p<0.05). Unwarranted visits were significantly lower in 2020 (19%) as compared to 2018 (22%) and 2019 (24%). Surgical and injury-related discharge diagnoses increased by 6% in 2020 (p<0.001), with a significant rise in trauma and foreign-body injuries (p<0.05). With regard to disease-related discharge diagnoses, we observed a significant rise in mental, behavioral, and social issues (p<0.01). Conversely, there was a significant (p<0.01) drop in diagnoses of acute infectious diseases in 2020 compared with 2018 and 2019. CONCLUSION: Lockdown was associated with a massive reduction in the number of PED visits, a significant change in primary discharge diagnoses, and a decrease in the proportion of unwarranted PED visits compared to the previous 2 years. This should encourage public health researchers to examine how to alleviate the burden of unnecessary PED visits.

Effectiveness of multifunction paediatric short-stay units: a French multicentre study.

AIM: To describe the characteristics of the activities of multifunction paediatric 'short-stay units' (SSU) including observation unit (OU), medical assessment and planning unit (MAPU) and holding unit (HU), to evaluate their effectiveness and to explore predictors of inappropriate admissions for OU patients. METHODS: Admissions to nine French paediatric SSUs were analysed. The main outcome measures were SSU length of stay with associated outcome for all patients and appropriate admission rate for OU patients. RESULTS: Of 1084 patients included in the study, 66% were OU patients (n = 718), 21% MAPU patients (n = 225) and 13% HU patients (n = 141). The OU patients constituted the majority of the SSU admissions. The appropriate OU admission rates ranged from 52% to 86%. Head trauma and seizure were the conditions with the highest appropriate OU admission rates (82%). Age <1 year, and need for IV fluids or medications, CT-Scan or MRI and cardiorespiratory monitoring were associated with an increased risk of inappropriate OU admission. Eighteen per cent of the MAPU patients and 5% of the HU patients were discharged home within 24 h. CONCLUSION: By providing extended and easily available facilities for diagnostics and early treatment for a wide range of sick children, the French paediatric SSU is an effective model for 'observation medicine' in emergency department-managed units. The experience and principles may be applicable to similar units in other health care systems.

Child abuse and neglect in a pediatric emergency department: epidemiology and outcome.

INTRODUCTION: Managing child abuse and neglect in pediatric emergency departments (PEDs) is difficult because of the complexity of screening and the prolonged care process. This study's main objective was to measure the child protection activity in a PED. METHODS: A retrospective, single-center study was conducted in the PED of the Lille University Hospital from 16 September∫2017 to 11 February 2019. All patients who required a social evaluation by the PED staff were included. Children admitted at first to the PED but for whom social management was exclusively performed by other units were not included. The whole population was analyzed first and then by type of abuse. The primary endpoint was the rate of patients who needed social management in the PED. The length of stay in the PED, the number of reports for investigation by child protective services, and reports to a judge were secondary assessment criteria. RESULTS: The study involved 245 patients (median age, 5 years; interquartile range [IQR], 2-13; boys, 49%), accounting for 0.6% of the PED visits. The main reasons for visiting the PED were somatic complaints (31%), sexual assault (23%), and behavioral disorders (20%). The median length of care in the PED was 5 h (IQR, 3-13). Thirty-three percent of the patients were monitored in the short-stay unit of the PED; 78% returned home. The main social measures taken were reports to child protective services (34%) and reports to a judge (24%); 51% of the patients required further actions by the PED physician after discharge. CONCLUSION: Management of child abuse in the PED is important and time-consuming. A hospital team specialized in child protection is essential for the initial care and monitoring of child victims.

Evolution between 2008 and 2018 of mothers' perception regarding vaccination and infant vaccine coverage in France.

OBJECTIVE: Monitoring of vaccination coverage rates (VCRs) is essential to assess the implementation of a country's vaccine policy and its effectiveness. Through the French Vaccinoscopy study, we measured the evolution of VCRs as well as mothers' opinion towards vaccination between 2008 and 2018, before and after implementation of infant mandatory vaccination extension. METHODS: This is a study based on an internet-standardised questionnaire. In 2018, a representative sample of 3000 mothers of infants 0 to 35 months of age answered on their opinion on vaccination and reported all vaccinations recorded in their child's health record. RESULTS: On the period considered, infant VCRs were stable and high for diphtheria, tetanus, poliomyelitis, pertussis and pneumococcus components and progressed for measles, mumps rubella, 2 doses at 24 months of age from 45.3% in 2008 to 81.0% in 2018, hepatitis B (HepB) complete primovaccination at 6 months of age from 45.9% in 2008 to 86.3% in 2017 and 95.5% in 2018, and meningococcus C (MenC) 1 dose at 6 months of age from 43.0% in 2017 to 74.2% in 2018. In 2018, 69.0% of mothers were in favour of vaccination while this rate dropped from 80.2% in 2012 to 64.0% in 2017, and 80.8 to 89.6% perceived HepB, MenC measles and pertussis vaccinations as useful/essential, percentages in progress versus 2017. CONCLUSION: Following the implementation of infant mandatory vaccination in 2018, proportion of mothers in favour of vaccination increased significantly. HepB and MenC VCRs significantly progressed between 2017 and 2018.

Small intestinal adenocarcinoma in common marmosets (Callithrix jacchus).

Small intestinal adenocarcinomas are uncommon neoplasms that are rarely reported in nonhuman primates. These neoplasms are also rare in humans, although they are thought to share a similar pathogenesis with the more common colorectal carcinoma. Herein the authors report the clinical, histologic, immunohistochemical, and molecular characteristics of small intestinal adenocarcinoma in 10 common marmosets (Callithrix jacchus). Retrospective analysis of necropsy records revealed small intestinal carcinoma to be the most common neoplastic cause of morbidity and mortality in aged common marmosets. The average age of affected animals was 6.6 years old, and there was no sex predilection. Nine of 10 (90%) tumors arose within the proximal small intestine near the interface with the duodenum. All cases were characterized by disorganization, loss of polarity, and proliferation of neoplastic epithelial cells along the crypt to midvillous interface. Two of 10 (20%) were defined as carcinoma in situ. Eight of 10 (80%) had some degree of invasion, with lymphatic invasion and lymph node metastasis present in 6 of 10 (60%) animals. Immunohistochemically, 10 of 10 (100%) expressed cytokeratin; 7 of 9 (77%) expressed E-cadherin; and 8 of 9 (88%) expressed beta-catenin. The expression of E-cadherin and beta-catenin was decreased in the cell membrane and increased in the cytoplasm. No Helicobacter-like bacteria were observed via silver stain, and callitrichine herpesvirus 3 was detected by polymerase chain reaction with equal frequency from neoplastic and nonneoplastic intestinal sections. The tumors described in this population illustrate comparable features to human cases of small intestine carcinoma and may serve as a potential animal model for small intestinal carcinomas.

Rebound in the incidence of pneumococcal meningitis in northern France: effect of serotype replacement.

AIM: To determine whether the recent emergence of nonvaccine pneumococcal serotypes has affected the incidence of pneumococcal meningitis in children a few years after the introduction of the heptavalent pneumococcal conjugate vaccine. METHODS: We conducted a multicentre retrospective cohort study from 2005 to 2008 in all hospitals with paediatric units in northern France. It included all patients < 18 years of age who were admitted for laboratory-confirmed pneumococcal meningitis during the study period. Data were collected from medical files and laboratory records at each hospital and compared with the regional hospital discharge codes. We assessed global and age-specific incidence rates of pneumococcal meningitis from 2005 through 2008, compared them with those from the prevaccine era (2000-2002) and evaluated pneumococcal serotypes. RESULTS: In all, 41 cases were found during the study period. The incidence rate of pneumococcal meningitis varied from 0.8/100,000 children < 18 years in 2005 to 1.8/100,000 children in 2008 (2.2-fold increase, p = 0.06); and from 1.8 to 11.9/100,000 children < 2 years (6.5-fold increase, p = 0.004). This increase was caused by nonvaccine pneumococcal serotypes. CONCLUSION: The incidence of pneumococcal meningitis in infants has rebounded in northern France during the pneumococcal conjugate vaccine programme, with the emergence of nonvaccine pneumococcal serotypes.

Simulation-based pediatric training: A French national survey.

INTRODUCTION: To have an overview of pediatric medical simulation within a country would be helpful to improve the offer and quality of teaching. The main objective of this study was to identify the scope for simulation-based teaching in pediatrics in France. METHODS: An assessment of professional practices was conducted by means of a national survey conducted among all university hospitals between 20 May and 6 August 2018. A standardized GoogleForm® was created and sent to heads of simulation centers or persons responsible for pediatric simulation. Descriptive analyses and comparisons of centers with and without university trainers as well as with and without research activity were performed. RESULTS: All 34 teaching hospitals or faculties of medicine responded to our survey. Of these, 31 had a simulation center. There was a median of nine trainers per center (interquartile range: 5-13). Most used simulation for communication and teamwork, as well as for technical and relational skills. These sessions were mainly dedicated to residents and health professionals. All centers reported working on high-fidelity newborn mannequins and 84% used low-fidelity newborn mannequins. Research activity was declared by 14 centers (45%), but only six of these had at least one publication. No difference was identified between centers with and without university trainers or with and without research activity. CONCLUSION: Compared with the 2012 report, 19 new centers have emerged within 6 years in France (+158%). Pursuing research to evaluate the impact of simulation programs on physician skills and patient management would appear to be important.

Infant mandatory vaccinations: Confirmation of a positive impact.

OBJECTIVE: Infant vaccines protecting against 11 diseases have changed from recommended to mandatory status in France for all children born from first of January 2018. Through Vaccinoscopie survey, we measured for the second consecutive year the impact of this new policy on vaccine coverage rates (VCRs) and mothers' perception regarding vaccination. METHODS: Web-based survey on a representative sample of 1500 mothers of 0 to 17-month-old infants. RESULTS: Non-optimal VCRs continued to increase in 2019 versus 2017 (according to age, +7 to 8 points VCR for Hepatitis B and +36 to 68 points for Meningococcus C). After a progressive decrease between 2012 and 2017, the rate of favorable mothers' opinion towards vaccination continued to progress in 2018 and 2019. CONCLUSION: These results confirmed the positive impact of this new law on infant VCRs and mothers' favorable opinion regarding vaccination.

Parental acceptance of an intranasal vaccine: Example of influenza vaccine.

BACKGROUND: Influenza vaccination coverage of children with chronic disease is insufficient in France, although a nasal live attenuated influenza vaccine (LAIV) has been approved. OBJECTIVE: We aimed to evaluate the acceptance of nasally administered vaccines by parents of children with chronic illness, by comparing LAIV vs. injectable inactivated influenza vaccine (IIV) acceptance. METHODS: We performed a retrospective, observational study (December 2014 to April 2015) including parents of all children vaccinated with the LAIV during the 2013-2014 influenza vaccination campaign at our university hospital. It was an opinion survey on the tolerance and acceptance of the LAIV. RESULTS: A standardized evaluation form was completed by 67/79 parents of all children who received the LAIV (mean age: 113±56 months; 64% with a chronic respiratory disease). The parents responded that vaccines in general were important (99%) but only 58% of them accepted the injectable route of administration. Of the 48 parents of children who had received both LAIV and IIV in the past, global opinion (P<0.0001) and tolerance (P<0.0001) were better for LAIV. For the future, 81% of parents would prefer LAIV, mainly because of needle absence and/or less painful character, and 18% IIV, mainly because of easier administration or habit. CONCLUSION: The better acceptance of a nasally administrated vaccine could increase vaccination coverage in the future for nasal vaccines.

Impact of the Sofia® Influenza A+B FIA rapid diagnostic test in a pediatric emergency department.

OBJECTIVE: The objective of this study was to evaluate the impact of a rapid diagnostic test for influenza (the Sofia® Influenza A+B FIA rapid diagnostic test [RDT]) in a pediatric emergency department (PED). METHODS: A retrospective, observational, cross-sectional study was conducted in the PED of the Lille University Hospital between 2013 and 2015. All patients under 18 years of age for whom influenza RDT was administered were included. Clinical data, management, and related hospitalizations were compared between positive and negative RDT groups. The length of stay in the PED (main outcome) and the number of additional tests (biological and radiographic tests) between the two groups were compared. RESULTS: A total of 238 tests were reported: 119 positive, 110 negative, nine invalid. The mean length of stay in the PED was significantly lower in the positive RDT group: 4.0h vs. 7.4h (P<10-6). Patients with positive RDT had significantly fewer biological tests (20% vs. 56%; P<10-7) and radiographs (23% vs. 52%; P<10-5). The prevalence of hospitalizations in a short-stay unit was significantly lower in patients with positive RDT (0.8% vs. 9.1%; P=0.009). CONCLUSIONS: This study showed a significant medical impact of the use of Sofia® Influenza RDT A+B FIA in a PED regarding the length of stay and the number of additional explorations.

Meningococcal C vaccine coverage in France in infants, children, and adolescents.

OBJECTIVES: Meningococcal C (MenC) vaccination was introduced in the French vaccination calendar in 2010 to reduce the incidence of invasive meningococcal C disease (IMDC), mainly through herd immunity. The Vaccinoscopie survey helps follow vaccination coverage rates (VCRs) of children. METHODS: This annual survey is based on a self-administered online questionnaire. In 2017, 4500 mothers of children completed the questionnaire and reported all vaccinations recorded in their child's health record. RESULTS: MenC vaccination was deemed indispensable or useful by 77% to 84% of mothers. The main barrier mentioned by mothers considering the vaccination useless/not very useful, was fear of adverse effects. VCR was estimated at 77% among 24-35-month-old infants, 79% among 6-year-old children, and 50% among 14-15-year-old adolescents. VCR strongly varied depending on the physician's advice for vaccination and on the type of follow-up. Six months after publication of the new French vaccine calendar in April 2017, with a MenC vaccine recommendation for all 5-month-old infants, 43% of infants had received a dose at 6 months of age. CONCLUSIONS: VCRs are insufficient to reach herd immunity. Between 2011 and 2017 more than 100 deaths could have been avoided in France if optimal VCRs had been achieved. Faced with this vaccine strategy failure, the new vaccine recommendation at 5 months of age seems well-accepted. This recommendation and the implementation of infant mandatory vaccination in 2018 should have a major impact on IMD C incidence in this age group.

Impact of mandatory vaccination extension on infant vaccine coverages: Promising preliminary results.

OBJECTIVE: In France infant vaccines protecting against 11 diseases have changed from a recommended to a mandatory status for all children born on or after January 1, 2018. Using the Vaccinoscopie survey, we measured the impact of this new vaccination policy on vaccine coverage rates (VCRs) and on mothers' perception of vaccination. METHODS: Online survey with 1000 mothers of 0- to 11-month-old infants. RESULTS: VCRs for at least one dose at the age of 6 months strongly progressed for diseases that previously did not meet Public Health objectives (+8 points for Hepatitis B and +31 points for meningococcal C vaccines). Mothers were more favorable to mandatory vaccination and better informed in 2018 than in 2017. CONCLUSION: These first results showed a positive impact of the extension of mandatory vaccination on mothers' opinion regarding vaccination and on infant VCRs.

Epidemiology of malpractice lawsuits in paediatrics.

UNLABELLED: A systematic review of malpractice lawsuits involving children identified six articles and 227 cumulative paediatric published cases. The prevalence of medical lawsuits resulting in payment to plaintiff was found to be 50% less frequent than that in adults. The most frequent and severe errors were among infants, including diagnostic errors of meningitis, gastroenteritis and pneumonia. The most implied unit was emergency department (58%). The patients and/or families were compensated in 23- 68% of cases. CONCLUSION: These data can increase physicians' awareness of disorders and age groups at high risk of medical errors. This could lead to minimize the risk of medical malpractices and to improve patient safety.

Extended-spectrum ß-lactamase-producing Enterobacteriaceae, national study of antimicrobial treatment for pediatric urinary tract infection.

OBJECTIVE: To evaluate clinical practices for ESBL-producing urinary tract infection (UTI) in France. METHODS: We performed an observational, retrospective, cross-sectional, hospital-based study in 22 pediatric departments of university or secondary care hospitals. We collected data of the last five patients presenting with ESBL-producing UTI in 2012 and the physicians' therapeutic approach to two case vignettes of acute non-septic ESBL-producing pyelonephritis (7-month-old girl) and cystitis (30-month-old girl). The adequacy of the therapeutic decision was analyzed by a panel of independent infectious disease experts. RESULTS: A total of 80 case patients of ESBL-producing UTI were collected: 54 with acute pyelonephritis (mean age: 28 months, female: 66%), of whom 98% received an intravenous ESBL-adapted antibiotic treatment and 55% a two-drug antibiotic therapy. Carbapenems were used in 56% of cases and aminoglycosides in 36%. Of the 26 cystitis patients (mean age: 5 years, female: 73%), 85% were treated with antibiotics, including three intravenously (carbapenems=2). For the case vignettes, physicians (n=85) would have treated the pyelonephritis patient with carbapenems (76%) and/or aminoglycosides (68%); 71% would have used a two-drug antibiotic treatment. The cystitis patient would have been treated intravenously by 29% of physicians; 8% would have used a two-drug antibiotic treatment, 16% would have prescribed carbapenems, and 11% aminoglycosides. Antibiotic treatments were deemed appropriate in 37% of cases. CONCLUSIONS: Antimicrobial treatment for ESBL-producing UTI greatly varies, and carbapenems are excessively prescribed. Specific guidelines for ESBL infections are required.
