A French study of cocaine intoxication/exposure in children (2010-2020).

BACKGROUND AND OBJECTIVE: In the European Union, the record of cocaine-related seizures indicates an expanding supply. The purity has also been increasing. The health impact of these trends remains poorly documented, in particular, the changes and clinical manifestations of intoxication in young children. We attempted to evaluate the trend in French pediatric admissions for cocaine intoxication/exposure over an 11-year period (2010-2020). METHODS: A retrospective, national, multicenter, study of a pediatric cohort. All children less than 15 years of age admitted to a tertiary-level pediatric emergency unit for proven cocaine intoxication (compatible symptoms and positive toxicological screening) during the reference period were included. RESULTS: Seventy-four children were included. Forty-six percent were less than 6 years old. Annual admissions increased by a factor of 8 over 11 years (+700%) and 57% of all cases were admitted in the last two years. The main clinical signs were neurologic (59%) followed by cardiovascular symptoms (34%). Twelve patients were transferred to the pediatric intensive care unit. Factors significantly associated with the risk of being transferred to the pediatric intensive care unit were initial admission to the pediatric resuscitation area (P < 0.001), respiratory impairment (P < 0.01), mydriasis (P < 0.01), cardiovascular symptoms (P = 0.014), age of less than 2 years (P = 0.014). Blood and/or urine toxicological screening isolated eighteen other substances besides cocaine in 46 children (66%). CONCLUSION: Children are collateral victims of the changing trends in cocaine availability, use and purity. Admissions of intoxicated children to pediatric emergency departments are more frequent and there is an increase in severe presentations. Therefore, this is a growing public health concern.

Analysis of the impact of the SARS-CoV-2 infection on the pediatric population hospitalized during the pandemic in the Greater Paris University Hospitals.

Background: The clinical characteristics, disease progression and outcome in children affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection appear significantly milder compared to older individuals. Nevertheless, the trends in hospitalization and clinical characteristics in the pediatric population seem to be different over time across the different epidemic waves. Objective: Our aim was to understand the impact of the different COVID-19 variants in the pediatric population hospitalized in the Pediatric Departments of the Public Hospital in the Greater Paris area by the analysis performed with the Assistance Publique-Hopitaux de Paris (AP-HP) Health Data Warehouse. Methods: This is a retrospective cohort study including 9,163 patients under 18 years of age, hospitalized from 1 March 2020 to 22 March 2022, in the Paris area, with confirmed infection by SARS-CoV-2. Three mutually exclusive groups with decreasing severity (Pediatric Inflammatory Multisystem Syndrome (PIMS), symptomatic infection, mild or asymptomatic infection) were defined and described regarding demography, medical history, complication of the SARS-CoV-2 infection, and treatment during admission. Temporal evolution was described by defining three successive waves (March-September 2020, October 2020-October 2021, and November 2021-March 2022) corresponding to the emergence of the successive variants. Results: In the study period, 9,163 pediatric patients with SARS-CoV-2 infection were hospitalized in 21 AP-HP hospitals. The number of patients with SARS-CoV-2 infection increased over time for each wave of the pandemic (the mean number of patients per month during the first wave was 332, 322 during the 2nd, and 595 during the third wave). In the medical history, the most associated concomitant disease was chronic respiratory disease. Patients hospitalized during the third wave presented a higher incidence of pulmonary involvement (10.2% compared to 7% and 6.5% during the first and second waves, respectively). The highest incidence of PIMS was observed during the first and second waves (4.2% in the first and second waves compared to 2.3% in the 3rd wave). Discussion: This analysis highlighted the high incidence of hospitalized children in the Greater Paris Area during the third wave of SARS-CoV-2 pandemic corresponding to the Omicron Covid-19 variant, which is probably an expression of a concomitant SARS-CoV-2, while a decreased incidence of PIMS complication was observed during the same period.

Injuries and child abuse increase during the pandemic over 12942 emergency admissions.

INTRODUCTION: A strict lockdown was decided from 17/03/2020 to 11/05/2020 in France in order to tackle the first wave of the COVID19 pandemic. In the Great Paris region, several areas are severely affected by overcrowding, creating difficult conditions for children and their families during a period of nearly two months. The objective was to assess the effects of the 2020 spring lockdown on injuries, child abuse and neglect. MATERIAL AND METHODS: The central medical data warehouse was screened for all pediatric admissions at emergency and critical care departments of 20 hospitals, in a cohort of 12942 children. Specific keywords were used to screen for both injuries and child abuse and neglect. RESULTS: We found head and neck trauma (1.2% in 2020 vs. 0.7% in 2019, p<0.001), burns (0.6% in 2020 vs. 0.1% in 2019, p < 0.001), lacerations (0.5% in 2020 vs. 0.3% in 2019, p<0.001), fractures (0.5% in 2020 vs. 0.3% in 2019, p<0.017), dog bites (0.1% in 2020 vs. 0.0% in 2019, p<0.001), and child abuse and neglect (18 cases during the 2020 lockdown vs. 24 cases in 2019, p=0.005) were significantly more prevalent during this period than during the same control period in 2019. CONCLUSIONS: These results indicate that specific prevention measures are crucial if strict lockdowns are to be decided in the future.

Impact of public health measures on the post-COVID-19 respiratory syncytial virus epidemics in France.

Since the beginning of the COVID-19 pandemic, other respiratory illnesses decreased worldwide. This study described the consequences of public health measures on respiratory syncytial virus (RSV) severe infections in France, where an interseasonal resurgence of RSV occurred recently. All patients admitted to Necker Hospital (Paris) between August 2018 and April 2021 with a diagnosis of RSV-associated acute lung respiratory infection (ALRI) were enrolled. Characteristics of subjects with RSV-associated ALRI in 2020/2021 were compared to those infected during the two previous outbreaks. Overall, 664 inpatients were diagnosed with RSV-associated ALRI: 229, 183, and 252 during the 2018/2019, 2019/2020, and 2020/2021 outbreaks, respectively. During autumn 2020, a national lockdown began in France but schools remained open. A 3-month delayed RSV epidemic occurred at the end of this lockdown. Compared to previous outbreaks, the 2020/2021 epidemics involved more children aged 6 to 11 months (25.8% versus 13.1%, p < 0.0001), but less infants aged < 6 months (41.3% versus 56.6%, p < 0.0001) and less adults (0.0 versus 2.7%, p < 0.0001). Shorter length of stay at hospital, less frequent requirement of admission to intensive care unit, use of non-invasive ventilation, and/or high-flow nasal oxygen were observed in 2020/2021 than during previous epidemics (p < 0.0001). Delayed RSV outbreak was associated with more hospitalizations for ALRI, higher age of pediatric inpatients, but milder median clinical phenotype. Reinforced public health measures (even while keeping nurseries and schools open with mandatory face masks since six years of age) could impact, at least transiently, the burden of RSV-related hospitalizations.

Forecasting the Patients Flow at Pediatric Emergency Departments.

Emergency departments (EDs) have a key role in the public health system. They are facing a constant growth of their volume. Forecasting the daily volume is a major tool to adapt the allocation of resources. In this paper, we focus on pediatric EDs. They are specific by their strong seasonal variation, determined by the academic pace. The main contribution of this paper is to integrate the effects of this pace to the annual seasonality. We also tried out to improve the daily forecasting by forecasting the week means of the flow first. We trained and tested these models specifically on the pediatric EDs of Paris university hospital trust. For the eight pediatric EDs gathered, on average for the years 2016 to 2019, we forecasted the daily volume with a Mean Absolute Percentage Error (MAPE) of 6.6% for a 7-days forecasting, 7.1% for a 14-days forecasting and 7.6% for a 28-days forecasting. Account of rhythm allows a performance increase, with results respectively 7%, 10.1% and 8.4% better relatively to a baseline model based on a periodic regression on the weeks.

Identification and comparison of France to other countries of the teaching of research to nursing students: Results of an international survey of nursing educator.

PURPOSE: Registered nurses must have a level of scientific literacy to be able to interpret research data and access Scientific's knowledge. Several studies have been conducted to explore barriers and levers to the dissemination of nurse's knowledge; however, the scientific literacy that nursing students acquire has not been studied. OBJECTIVE: The aim was to examine and compare the way that research is taught to undergraduate nursing students in France and other countries. DESIGN: Cross-sectional, Internet survey. SETTINGS: Universities providing undergraduate nursing programs around the world. PARTICIPANTS: Nurses educators. METHODS: Schools of nursing and universities were contacted by mail, through social networks and with the help of national or international nursing organizations. Respondents provided demographic data on schools and faculties of nursing, the teaching of scientific databases, Reading Critical Analysis and the teaching of scientific English. Information on the transmission of articles and access to scientific knowledge by students through the institution were also requested. FINDINGS: A total of 245 nursing schools/universities participated. Most respondents were educational research referees (52.2%), worked in a public institution (85.7%) and were in the nursing program leading to a bachelor's degree (74.3%). Databases were taught at 56.8%, Critical Reading of Articles at 70.1%, scientific English at 60.6% of nursing schools or universities. Articles were provided to students at 89.6% of institution and students had access to data through the institution in 66.1% of nursing schools or universities. Several significant differences were found between French schools of nursing and nursing schools/universities in other countries. CONCLUSIONS: Our results show that most schools or universities of nursing teach the three majors' components to promote, provide articles to students and give access to scientific knowledge. However, there is wide heterogeneity between countries. There is a need to standardize research education for nursing students worldwide to promote the development of scientific literacy skills.

Predictors of clinically urgent intracranial pathology at neuroimaging in children with complex febrile seizures: a retrospective cross-sectional study.

AIM: To assess the prevalence of clinically urgent intracranial pathology (CUIP) in children visiting the emergency department with a complex febrile seizure (CFS). METHODS: Retrospective cohort review. We analysed the visits of patients for a CFS from January 2007 to December 2011 in seven paediatric emergency departments. Our main outcomes were the proportions of CUIP diagnosed between day 0 and 1 and within 30 days after the index visit. RESULTS: From 1 183 487 visits, 839 were for a CFS and 130 (15.5%) of these had a neuroimaging performed within 30 days (CT scan for 75 visits [8.9%], MRI for 30 visits [3.6%] and both for 25 visits [3.0%]). Three CUIP were diagnosed between day 0 and 1 (0.4% [CI-95%: 0.1-1.3]), 5 within 30 days after the index visit (0.7% [CI-95%: 0.2-1.7]) but none among the 630 visits of children presenting with a normal neurological clinical examination (0% [95% CI: 0.0-0.7]), nor among the 468 presenting only with multiple seizure (0% [95% CI: 0.0-1.0]). CONCLUSION: In children with a CFS, CUIP is rare event in the subgroup of children with a normal neurological clinical examination and in those with brief generalised multiple seizures.

Study characteristics impacted the pragmatism of randomized controlled trial published in nursing: a meta-epidemiological study.

OBJECTIVES: The objective of this study was to examine the impact of study characteristics on the score of the pragmatism/explanatory continuum of randomized controlled trials (RCTs) published in nursing journals using the PRagmatic Explanatory Continuum Indicator Summary (PRECIS)-2 tool. STUDY DESIGN AND SETTING: RCTs concerning five themes of nursing care indexed in the PubMed and CINAHL databases published from 2002 to 2005 and 2012 to 2015 were selected by title/abstract. A sample of 400 was randomly selected and evaluated with the PRECIS-2 tool and reading grid. RESULTS: The median PRECIS score was 32 of a possible 45 [28; 36] corresponding to a medium level of pragmatism. Studies with "medication" as an intervention had a more explanatory PRECIS score than studies with other intervention types (P = 0.015). Studies with "placebo" and "no usual care" as comparators had a more explanatory PRECIS score (P = 0.0027). The pragmatism/explanatory level was unaffected by impact factor (P = 0.42), h-index of the first and last author (P = 0.27 and P = 0.25, respectively), funding (P = 0.32), blinding (P = 0.41), sample size (P = 0.22), and time (P = 0.11). CONCLUSION: This study highlights the pragmatism/explanatory level of nursing RCTs, the impact of the field of the article, and the comparator type on the pragmatism of these studies. Further studies are needed to confirm the astonishing result that blinding resulted in no significant difference in the PRECIS score.

Parents' and children's comprehension and decision in a paediatric early phase oncology trial: a prospective study.

OBJECTIVE: To analyse parents' and children's understanding of consent information and assess their decision-making process in paediatric oncology. DESIGN: Prospective observational study. SETTINGS: Eleven French paediatric oncology units. PATIENTS: Parents and children who have been asked to give consent for participation in an early phase trial. INTERVENTIONS: Thirty-seven children and 119 parents were questioned using an audio-recorded semistructured interview. MAIN OUTCOME MEASURES: The participants' understanding of nine elements of the informed consent was assessed by comparing their answers with the informed consent leaflet. Their decision-making process was also evaluated. RESULTS: Most parents and children had an excellent understanding regarding their participation in a clinical trial (respectively 88.2% and 48.6%), the right to withdraw (76.5% and 43.2%) and the prospects of collective benefits (74.8% and 48.6%). By contrast, less than half of the parents and few of the children correctly understood the alternatives (respectively 47.5% and 27%), the risks related to participation (44.5% and 10.8%), the prospects of individual benefits (33.6% and 10.8%) and the purpose of the clinical trial (12.6% and 2.7%). Twenty-six (70.3%) children participated in the decision-making process. Most parents and children felt they had no choice but to participate in the trial to have access to a new anticancer treatment. CONCLUSIONS: What might appear to be a poor understanding of the research protocol may actually correspond to the families' interpretation of the situation as a coping mechanism. All children (except infants) should get age-tailored information in order for them to have a meaningful involvement in research.

Comparison of the Quality of Pediatric Randomized Controlled Trials Published in Both Nursing and Medical Journals: Adherence to the CONSORT Statement.

BACKGROUND: Nursing care should be based on scientific evidence. However, studies must be performed rigorously with accurate reporting for their findings to be applicable to practice. Since the body of scientific nursing literature is broad, the quality and validity of its findings should be regularly controlled and verified to ensure their application and their practical impact. PURPOSE: To compare reporting quality of pediatric randomized controlled trial (RCT) articles in nursing and medical journals. METHODS: Randomly selected articles were reviewed and scored to assess the number of CONSORT items that were adequately reported, generating a CONSORT score. The CONSORT scores for 28 items were compared between the two journal types. RESULTS AND DISCUSSION: The CONSORT scores by journal type were not significantly different: (19.2 [16.2; 22] for medical journals and 19.5 [16.1; 21.5] for nursing journals, p = .77). The reporting of CONSORT items was poor for both journal types. However, there were two significant differences: item 19 (Declaration of all important harm or unintended effects, p = .0006) and item 23 (Registration number of the study, p = .0003), were reported more often in medical journals. The adherence of journals to the CONSORT statement and large sample size was associated with better quality of the reporting of studies. CONCLUSIONS: Based on reporting quality, nursing studies have the same scientific credibility and rigor as medical studies in the pediatric field. LINKING EVIDENCE TO ACTION: The findings of this study could help researchers improve the reporting of their studies and highlight the importance of reporting quality for future knowledge transfer and practical use. The quality of research and its reporting is necessary to improve knowledge transfer into practice.

Provided information and parents' comprehension at the time of admission of their child in pediatric intensive care unit.

This study evaluated the first interaction (FI) between parents and health care providers at the time of admission of a child in pediatric intensive care unit (PICU), and explored the extent to which parents understood the medical information. This prospective study took place in three French university-affiliated PICUs. Forty-two parents of 30 children were interviewed. The physician and nurse who took care of the child completed a questionnaire. We evaluated parents' comprehension (excellent, fair, or poor) by comparing parents' and physicians' responses to six items: diagnosis, affected organ, reason for hospitalization, prognosis, treatments, and further investigations. Parent-physician FI occurred within 24 h of child's admission. Two thirds of the parents were dissatisfied to wait before receiving information. Most of the parents had an excellent comprehension of the affected organ (n = 25/28, 89.3%) and prognosis (n = 26/30, 86.7%). Two thirds of the parents understood the reason for hospitalization (n = 18/28, 64.3%) and diagnosis (n = 19/30, 63.3%). Less than half the parents understood child's treatments (n = 10/30, 33.3%) and further investigations (n = 8/21, 38.1%). When a nurse delivered information on treatment, parental comprehension improved (p = 0.053). CONCLUSION: Parents complained of their wait time before receiving information. Most of them had an excellent comprehension. An improved communication between nurses and physicians is mandatory, and the active participation of nurses to give information to the parents should be encouraged. What is known: • In pediatric intensive care unit, health care providers deliver information to parents on their child's condition, which fosters the trust between them to build a partnership. • Various guidelines exist to help health care providers communicate with parents in PICU, but never mention the specific time of admission. What is new: • Even though parents could wait before entering the unit, they all received information on their child's condition within 24 hours after admission. • Parents understood the information well, and nurses improved the parental comprehension of the treatments by reformulating.

Fine particulate pollution and asthma exacerbations.

OBJECTIVE: As the results from epidemiological studies about the impact of outdoor air pollution on asthma in children are heterogeneous, our objective was to investigate the association between asthma exacerbation in children and exposure to air pollutants. METHODS: A database of 1 264 585 paediatric visits during the 2010-2015 period to the emergency rooms from 20 emergency departments (EDs) of 'Assistance Publique Hôpitaux de Paris (APHP)', the largest hospital group in Europe, was used. A total of 47 107 visits were classified as asthma exacerbations. Concentration of air pollutants (nitrogen dioxide, ozone, fine particulate matter (PM) with an aerodynamic diameter smaller than 10 µm (PM10) and 2.5 µm (PM2.5)), as well as meteorological data, evolution of respiratory syncytial virus infection and pollen exposition, were collected on an hourly or daily basis for the same period using institutional databases. To assess the association between air pollution and asthma, mixed-effects quasi-Poisson regression modelling was performed. RESULTS: The only compound independently associated with ED visits for asthma was PM2.5 (P<10-4). The association between asthma exacerbation and PM2.5 was not linear, and a sigmoid function described the relationshipsatisfactorily. PM2.5 concentration, which gives half the maximum effect, was estimated at 13.5 µg/m3. CONCLUSIONS: We found an association between daily asthma exacerbation in paediatric visits to the ED and fine particulate air pollutants.

Validation of a Novel Assay to Distinguish Bacterial and Viral Infections.

BACKGROUND: Reliably distinguishing bacterial from viral infections is often challenging, leading to antibiotic misuse. A novel assay that integrates measurements of blood-borne host-proteins (tumor necrosis factor-related apoptosis-inducing ligand, interferon γ-induced protein-10, and C-reactive protein [CRP]) was developed to assist in differentiation between bacterial and viral disease. METHODS: We performed double-blind, multicenter assay evaluation using serum remnants collected at 5 pediatric emergency departments and 2 wards from children ≥3 months to ≤18 years without (n = 68) and with (n = 529) suspicion of acute infection. Infectious cohort inclusion criteria were fever ≥38°C and symptom duration ≤7 days. The reference standard diagnosis was based on predetermined criteria plus adjudication by experts blinded to assay results. Assay performers were blinded to the reference standard. Assay cutoffs were predefined. RESULTS: Of 529 potentially eligible patients with suspected acute infection, 100 did not fulfill infectious inclusion criteria and 68 had insufficient serum. The resulting cohort included 361 patients, with 239 viral, 68 bacterial, and 54 indeterminate reference standard diagnoses. The assay distinguished between bacterial and viral patients with 93.8% sensitivity (95% confidence interval: 87.8%-99.8%) and 89.8% specificity (85.6%-94.0%); 11.7% had an equivocal assay outcome. The assay outperformed CRP (cutoff 40 mg/L; sensitivity 88.2% [80.4%-96.1%], specificity 73.2% [67.6%-78.9%]) and procalcitonin testing (cutoff 0.5 ng/mL; sensitivity 63.1% [51.0%-75.1%], specificity 82.3% [77.1%-87.5%]). CONCLUSIONS: Double-blinded evaluation confirmed high assay performance in febrile children. Assay was significantly more accurate than CRP, procalcitonin, and routine laboratory parameters. Additional studies are warranted to support its potential to improve antimicrobial treatment decisions.

Do All Children Who Present With a Complex Febrile Seizure Need a Lumbar Puncture?

STUDY OBJECTIVE: We assess the prevalences of bacterial meningitis and herpes simplex virus meningoencephalitis (HSV-ME) in children with a complex febrile seizure and determine these prevalences in the subgroup of children with a clinical examination result not suggestive of meningitis or encephalitis. METHODS: This multicenter retrospective study was conducted in 7 pediatric emergency departments (EDs) in the region of Paris, France. Visits of patients aged 6 months to 5 years for a complex febrile seizure from January 2007 to December 2011 were analyzed. We defined a subgroup of patients whose clinical examination result was not suggestive of meningitis or encephalitis. Bacterial meningitis and HSV-ME were sequentially sought for by analyzing bacteriologic and viral data at the visit, looking for data from a second visit to the hospital after the index visit, and telephoning the child's parents. RESULTS: From a total of 1,183,487 visits in the 7 pediatric EDs, 839 patients presented for a complex febrile seizure, of whom 260 (31.0%) had a lumbar puncture. The outcomes bacterial meningitis and HSV-ME were ascertainable for 715 (85%) and 657 (78.3%) visits, respectively, and we found 5 cases of bacterial meningitis (0.7% [95% confidence interval [CI] 0.2% to 1.6%]) and no HSV-ME (0% [95% CI 0% to 0.6%]). Among the 630 visits of children with a clinical examination result not suggesting meningitis or encephalitis, we found no bacterial meningitis (0% [95% CI 0% to 0.7%]) and no HSV-ME (0% [95% CI 0% to 0.8%]). CONCLUSION: In children with a complex febrile seizure, bacterial meningitis and HSV-ME are unexpected events when the clinical examination after complex febrile seizure is not suggestive of meningitis or encephalitis.

Epidemiology and neonatal pain management of heelsticks in intensive care units: EPIPPAIN 2, a prospective observational study.

BACKGROUND: Heelstick is the most frequently performed skin-breaking procedure in the neonatal intensive care units (NICUs). There are no large multicenter studies describing the frequency and analgesic approaches used for heelsticks performed in NICUs. OBJECTIVES: To describe the frequency of heelsticks and their analgesic management in newborns in the NICU. To determine the factors associated with the lack of specific preprocedural analgesia for this procedure. DESIGN: EPIPPAIN 2 (Epidemiology of Procedural PAin In Neonates) is a descriptive prospective epidemiologic study. SETTING: All 16 NICUs in the Paris region in France. PARTICIPANTS: All newborns in the NICU with a maximum corrected age of 44 weeks +6 days of gestation on admission who had at least one heelstick during the study period were eligible for the study. The study included 562 newborns. METHODS: Data on all heelsticks and their corresponding analgesic therapies were prospectively collected. The inclusion period lasted six weeks, from June 2, 2011 to July 12, 2011. Newborns were followed from their admission to the 14th day of their NICU stay or discharge, whichever occurred first. RESULTS: The mean (SD) gestational age was 33.3 (4.4) weeks and duration of participation was 7.5 (4.4) days. The mean (SD; range) of heelsticks per neonate was 16.0 (14.4; 1-86) during the study period. Of the 8995 heelsticks studied, 2379 (26.4%) were performed with continuous analgesia, 5236 (58.2%) with specific preprocedural analgesia. Overall, 6764 (75.2%) heelsticks were performed with analgesia (continuous and/or specific). In a multivariate model, the increased lack of preprocedural analgesia was associated with female sex, term birth, high illness severity, tracheal or noninvasive ventilation, parental absence and use of continuous sedation/analgesia. CONCLUSIONS: Heelstick was very frequently performed in NICUs. Although, most heelsticks were performed with analgesia, this was not systematic. The high frequency of this procedure and the known adverse effects of repetitive pain in neonates should encourage the search of safe and effective strategies to reduce their number.

The burden of venipuncture pain in neonatal intensive care units: EPIPPAIN 2, a prospective observational study.

BACKGROUND: Newborns in intensive care units (ICUs) undergo numerous painful procedures including venipunctures. Skin-breaking procedures have been associated with adverse neurodevelopment long-term effects in very preterm neonates. The venipuncture frequency and its real bedside pain management treatment are not well known in this setting. OBJECTIVES: To describe venipuncture frequency, its pain intensity, and the analgesic approach in ICU newborns; to determine the factors associated with the lack of preprocedural analgesia and with a high pain score during venipuncture. DESIGN: Further analysis of EPIPPAIN 2 (Epidemiology of Procedural Pain In Neonates), which is a descriptive prospective epidemiologic study. SETTING: All 16 neonatal and pediatric ICUs in the Paris region in France. PARTICIPANTS: All newborns in the ICU with a maximum corrected age under 45 weeks of gestation on admission who had at least one venipuncture during the study period. METHODS: Data on all venipunctures, their pain score assessed with the DAN scale and their corresponding analgesic therapies were prospectively collected. The inclusion period lasted six weeks, from June 2, 2011, to July 12, 2011. Newborns were followed from their admission to the 14th day of their ICU stay or discharge, whichever occurred first. RESULTS: 495 newborns who underwent venipunctures were included. The mean (SD) gestational age was 33.0 (4.4) weeks and duration of participation was 8.0 (4.5) days. A total of 257 (51.9%) neonates were very preterm (<33 weeks). The mean (SD; range) number of venipunctures per neonate during the study period was 3.8 (2.8; 1-19) for all neonates and 4.1 (2.9; 1-17) for neonates <33 weeks. Of the 1887 venipunctures, 1164 (61.7%) were performed successfully in one attempt, 437 (23.2%) with continuous analgesia, 1434 (76.0%) with specific preprocedural analgesia. In multivariate models, lack of preprocedural analgesia was associated with higher disease-severity score, intrauterine growth retardation, invasive or noninvasive ventilation, venipuncture performed on the first day of hospitalization or at nighttime, and the use of continuous sedation/analgesia. High pain scores were significantly associated with absence of parents during procedures, surgery during the study period, and higher number of attempts. CONCLUSIONS: Venipuncture is very frequent in preterm and term neonates in the ICUs. 76% were performed with preprocedural analgesia. Strategies to reduce the number of attempts and to promote parental presence seem necessary.

Risk of Bacterial Meningitis in Children 6 to 11 Months of Age With a First Simple Febrile Seizure: A Retrospective, Cross-sectional, Observational Study.

OBJECTIVES: National and international guidelines are very heterogeneous about the necessity to perform a lumbar puncture (LP) in children under 12 months of age with a first simple febrile seizure. We estimated the risk of bacterial meningitis in children aged 6 to 11 months with a first simple febrile seizure. METHODS: This multicenter retrospective study was conducted in seven pediatric emergency departments (EDs) in the region of Paris, France. Visits of patients aged 6 to 11 months for a first simple febrile seizure from January 2007 to December 2011 were analyzed. Bacterial meningitis was sequentially sought for by 1) analyzing bacteriologic data at the time of the visit, 2) looking for data from a second visit to the hospital after the index visit, and 3) phone calling the child's parents to determine the symptom evolution after the index visit. Infants lost to this follow-up were searched for in a national bacterial meningitis database. RESULTS: From a total of 1,183,487 visits in the seven pediatric EDs, 116,503 were for children 6 to 11 months of age. From these, 205 visits were for a first simple febrile seizure. An LP was performed in 61 patients (29.8%). The outcome bacterial meningitis was ascertainable for 168 (82%) visits. No bacterial meningitis was found among these patients (95% confidence interval = 0% to 2.2%). None of the 37 infants lost to our follow-up were registered in the national database as having bacterial meningitis. CONCLUSIONS: Among children between 6 and 11 months of age with a first simple febrile seizure, the risk of bacterial meningitis is extremely low. These results should encourage national and international societies to either develop or endorse guidelines limiting routine LP in these infants and contribute to widely homogenized management practices.

Determination of optimal vitamin D3 dosing regimens in HIV-infected paediatric patients using a population pharmacokinetic approach.

AIMS: To investigate 25-hydroxycholecalciferol [25(OH)D] population pharmacokinetics in children and adolescents, to establish factors that influence 25(OH)D pharmacokinetics and to assess different vitamin D3 dosing schemes to reach sufficient 25(OH)D concentrations (>30 ng ml(-1) ). METHODS: This monocentric prospective study included 91 young HIV-infected patients aged 3 to 24 years. Patients received a 100 000 IU vitamin D3 supplementation. A total of 171 25(OH)D concentrations were used to perform a population pharmacokinetic analysis. RESULTS: At baseline 28% of patients had 25(OH)D concentrations below 10 ng ml(-1) , 69% between 10 and 30 ng ml(-1) and 3% above 30 ng ml(-1) . 25(OH)D pharmacokinetics were best described by a one compartment model with an additional production parameter reflecting the input from diet and sun exposure. The effects of skin phototype and bodyweight were significant on 25(OH)D production before any supplementation. The basal level was 27% lower in non-white skin phototype patients and was slightly decreased with bodyweight. No significant differences in 25(OH)D concentrations were related to antiretroviral drugs. To obtain concentrations between 30 and 80 ng ml(-1) , patients with baseline concentrations between 10 and 30 ng ml(-1) should receive 100 000 IU per 3 months. However, vitamin D deficient patients (<10 ng ml(-1) ) would need an intensive phase of 100 000 IU per 2 weeks (two times) followed 2 weeks later by a maintenance phase of 100 000 IU per 3 months. CONCLUSIONS: Skin phototype and bodyweight had an influence on the basal production of 25(OH)D. According to 25(OH)D baseline concentrations, dosing schemes to reach sufficient concentrations are proposed.

Vitamin D deficiency and insufficiency in HIV-infected children and young adults.

BACKGROUND: Vitamin D insufficiency and HIV infection are both risk factors for chronic disorders, so it is important to consider vitamin D status in HIV-infected patients. METHODS: We prospectively investigated serum 25-hydroxyvitamin D (25(OH)D) concentrations, determined by radioimmunoassay, in 113 HIV-infected children (age≤24 years) and 54 healthy controls matched for age and phototype. We assessed the prevalence of vitamin D deficiency and insufficiency (VDD and VDI) defined as 25(OH)D titers of <10 ng/mL and between 10 and 30 ng/mL, respectively, and their predictive factors. RESULTS: The overall prevalence of VDD and VDI was 38.9% and 58.7%, respectively. Mean serum 25(OH)D concentrations were significantly higher in the HIV group than the control group (14.2±6.9 ng/mL vs. 10.4±5 ng/mL, P<0.001). Variables significantly associated with low serum 25(OH)D concentrations in HIV-infected children were dark phototype (P<0.001) and age (r=-0.19, P=0.03). Patients receiving efavirenz had a trend toward lower serum 25(OH)D concentrations (11.1±4.6 ng/mL vs. 14.6±7 ng/mL, P=0.1). Dark phototype was the only independent risk factor for VDD in HIV-infected children (odds ratio=14.6; 95% confidence interval: 2.4-89.9, P=0.004). CONCLUSIONS: VDD and VDI were common in both HIV-infected and control groups, and serum 25(OH)D concentrations were significantly lower in controls than in HIV-infected children.
