[CONSENSUS UPDATE OF THE POPI TOOL]. / MISE A JOUR PAR CONSENSUS DE L'OUTIL POPI.

Medication errors are one of the causes of iatrogenic medication use in children. The POPI tool for detecting inappropriate drug prescriptions and prescription omissions in paediatrics was the first tool to be published in this field in 2014. Our aim was to update the POPI tool for French use based on current recommendations and practice. Criteria were removed, updated or added based on recommendations from learned societies and national bodies. The two-round Delphi method was used to reach a consensus of experts. The level of agreement of the healthcare professionals' proposals was rated on a 9-point Likert scale. In the first round, only proposals with a median agreement of 7 to 9 and an agreement of more than 65% were retained. In the second round, only those with a median agreement of 7 to 9 and over 75% agreement were retained. The POPI tool now includes eight categories (various, infectiology, gastroenterology, pneumonology, dermatology, neurology/pedopsychiatry, haematology and excipients). All the criteria were supported by bibliographical references. They were submitted to 20 French healthcare professionals: 9 pharmacists and 11 doctors (17 hospital-based and 3 self-employed). After two rounds of Delphi testing, 166 criteria were retained and validated (111 inappropriate prescriptions and 54 omissions). In conclusion, this study made it possible to update the POPI tool, which is still available for assessing paediatric prescriptions.

[Social or judicial alert in child abuse: Announcement guidelines and simulation in child welfare training with standardized patients]. / Information préoccupante ou signalement dans les violences intrafamiliales : construction, validation et mise en application d'une grille d'annonce par technique de simulation en santé avec patients standardisés.

Child abuse is a major health problem that can lead to physical and psychological issues. Its diagnosis can be difficult and sensitive. Physicians are submitted by law to inform the parents when they report to child welfare services or judicial authorities, unless otherwise in the minor's interest. This exercise is destabilizing for both patients and physicians. The physician must be trained to detect and announce a possible diagnosis of child abuse. To facilitate and increase those reports, we have developed guidelines for the physicians to help the exercise of announcement. These guidelines were based on pre-existing recommendations about how to announce bad news. We have also planned to put into practice these guidelines with a communication skills training program based on standardized patients. We propose the acronym PROTECT; P for plural: never stay alone in such situations, R for remaining a caregiver and not becoming an investigator or judge, O for obligation to protect minors, T for time, to take enough time to inform the parents and the child but in a limited time frame, E for explaining to the parents what preoccupy the professionals; C for centring ourselves on the child, his or her symptoms, needs and pain; T for total care of the child that should integrate physical, psychological, and social child health, through a global and interdisciplinary approach in collaboration with child welfare services, and should involve also the child in the process. This tool will be applied by simulation in child welfare training with standardized patients. The evaluation of this tool and its application would need further study.

[Minors in a French custody center: Sociodemographic characteristics, global health and vulnerability factors]. / Mineurs en garde à vue: caractéristiques sociodémographiques, auto-évaluation de la santé et identification de facteurs de vulnérabilité.

Minor offenders are at risk for medico-psycho-social vulnerability, that impacts global health, schooling, professional future, and socio-familial environment; moreover, minors who are victims of violence and neglect are at greater risk of becoming offenders and minor offenders are at greater risk of suffering violence. Few data are currently available regarding global health and vulnerability factors for minors (i.e. those aged under 18) who have been placed in police custody. This study aimed to describe the judicial and social characteristics of these minors, their medical and psychological health status, with the hypothesis that most minors placed in police custody can be considered as abused or neglected, by presenting factors of vulnerability. We carried out a prospective study, including consecutive minors aged of 13 to 18 years old, who had been detained in custody at the Central Police Station of Nantes (France), from October 2012 to May 2013. The sociodemographic characteristics, scores for global health and the data collected from the welfare and judiciary services were analyzed, to identify abused or neglected minors. Ninety-nine teenagers were included: 78 males and 11 females (mean age±standard deviation: 16.5 years±1.01), who had been placed in custody for robbery, with a remarkable proportion of recidivist minors. Our study has highlighted several worrying characteristics of minors in police custody reflecting their vulnerability, as living conditions (no schooling, no fixed address) and irregular or absent medical follow-up; however their scores for global health were not different from the general population. While 49 minors (49.5 %) had already been identified by the welfare services, our study find that 35 added minors of this population should nonetheless be considered as being abused and/or neglected, based on a very high rate of minors already followed by child protection services and/or already penalized. Systematic health screening in custody could help to detect abused and/or neglected minors, in order to provide them access to appropriate medical and social cares. They could be referring to psychiatric or rehabilitation cares, and to the relevant welfare and judiciary services in order to assess if a specific protection measure is needed.

Preoperative Staphylococcus aureus Carriage and Risk of Surgical Site Infection After Cardiac Surgery in Children Younger than 1 year: A Pilot Cohort Study.

Surgical site infections (SSI) increase length of stay, morbidity, mortality and cost of hospitalization. Staphylococcus aureus (SA) carriage is a known risk factor of SSI in adults, but its role in pediatrics remains uncertain. The main objective of this pilot prospective monocentric cohort study was to describe the prevalence of SA colonization in children under 1 year old before cardiac surgery. The secondary objectives were to compare the incidence of SSI and other nosocomial infections (NI) between preoperative carriers and non-carriers. From May 2012 to November 2013, all children <1 year old undergoing cardiac surgery under cardiopulmonary bypass underwent preoperative methicillin-resistant (MRSA) and methicillin-sensitive SA (MSSA) screening using real-time PCR. The only exclusion criterion was invalid PCR. All patients were followed up to 1 year after the surgery regarding SSI and other nosocomial infections. Among the 68 studied patients, SA colonization prevalence was 26.5%, comprising 23.5% MSSA and 2.9% MRSA. There was no significant difference between colonized and non-colonized children regarding SSI rate (16.7 vs 20%; p = 0.53), but ventilator-associated pneumonia rate was significantly higher among the SA carriers (22.2 vs 2%; p < 0.05). The colonization rate was different depending on the age of the patients (p < 0.05). This pilot study highlights that colonization with MSSA is frequent whereas MRSA prevalence is low in our population. In this cohort, there was no association between SA colonization and SSI incidence but further studies are needed to analyze this association.

A new procalcitonin cord-based algorithm in early-onset neonatal infection: for a change of paradigm.

Diagnostic of early-onset neonatal infection (EONI) remains an emergency. Recent studies underline the potential benefit of using Procalcitonin (PCT) in early diagnosis of bacterial infections in neonates. The aim of this study was to evaluate the diagnostic value of an umbilical blood cord PCT based algorithm in newborns suspected of EONI. The diagnostic value of the PCT based algorithm was compared to the French one currently in use by analyzing an 18-months database of newborns suspected of EONI in University Hospital of Nantes from March 2011 to September 2012. Among the 2,408 (40.8 %) newborns suspected of infection during this period, 2,366 were included in the study. The incidence of EONI was 3.4‰ (n = 20). There was no significant difference between the sensibilities of the PCT based algorithm and the current algorithm (90 %, respectively, 95%CI 76.9-100 versus 85.4-100; p = 0.90) and between their specificities (respectively 91.7 % (90.6-92.8) versus 87.4 % (86-88.7); p = 0.25). The antibiotic treatment rate would be significantly reduced with the PCT based algorithm [211 i.e. 8.9 % (7.8-10) versus 314 i.e. 13.3 % (11.9-14.7) in the current algorithm; p < 0.005] and less biological analysis would be performed [301 i.e. 12.7 % (11.4-14) versus 937 i.e. 39.6 % (37.6-41.6); p < 0.005]. Blood cord PCT seems to be a new and efficient marker to guide neonatologists taking care of newborns suspected of EONI. The PCT algorithm seems to be a safe alternative in diagnosis of EONI, allowing detection of EONI significantly as well as the current algorithm, without resulting in a substantially higher number of missed infections. These results have to be confirmed by a multicentric validation study.

Healthcare-associated infection prevention in pediatric intensive care units: a review.

The objective of this review was to summarize the current knowledge base on the prevention of nosocomial infections in pediatric intensive care units (PICUs). Healthcare-associated infections (HAIs) are a crucial problem in PICUs because of their impact on patient outcome, length of hospital stay, and costs. Studies published between 1998 and 2011 were identified using the MEDLINE and Cochrane databases. Randomized, cohort, case-control studies, and meta-analyses concerning global strategies of prevention, general organization of the wards, general recommendations on antibiotic management, and measures for the prevention of ventilator-associated pneumonia (VAP), bloodstream infections (BSIs), urinary tract infections (UTIs), and surgical site infections (SSIs) were incorporated. Limits of age from 1 month to 18 years were used. When recommendations could not be supported by the pediatric literature, adult studies were also reviewed. This review excludes the neonate population. Specific pediatric data are often lacking so as to establish specific evidence-based pediatric recommendations. This review underlines the absolute necessity of pediatric studies and to harmonize the definitions of HAIs.

Umbilical cord blood procalcitonin as a risk factor for mortality in very premature infants.

Fetal inflammatory response syndrome is implicated as a cause of fetal or neonatal injury. We analyzed the relationship between the procalcitonin umbilical cord blood level and neonatal outcome. A total of 237 preterms born in a level III perinatal medicine unit of a French university hospital were enrolled in a prospective observational study. Measurement of the procalcitonin umbilical cord blood level was performed at birth. After hospitalization, surviving infants were enrolled in the regional follow-up program. Outcome data were recorded on standardized questionnaires. The main outcome measures were neonatal mortality and impaired functional outcome at 2 years of corrected age. The terciles of procalcitonin levels were calculated. Preterm infants of the third tercile were defined as infants with elevated procalcitonin. Among the 237 infants, 13 (5.5%) died during the neonatal period, 20 (8.4%) were lost to follow-up, and 31 (13.1%) were classified as having an impaired functional outcome. After adjustment, elevated cord blood procalcitonin (>0.33 ng/ml) was significantly associated with an increase in mortality (adjusted odds ratio [aOR] = 8.3 [1.4-48]; p = 0.018), but not with the 2-year impaired functional outcome (aOR = 1.0 [0.4-2.5]; p = 0.93). Elevated umbilical blood cord procalcitonin concentration is an independent risk factor of mortality in preterm infants at less than 33 weeks' gestation.

Umbilical cord blood procalcitonin level in early neonatal infections: a 4-year university hospital cohort study.

This article describes a study of procalcitonin (PCT) measured in cord blood as a discriminating marker of early-onset neonatal infection. This was a monocenter retrospective study with prospective collection of data including all babies born during the study period. Those presenting infection risk factors had PCT measurement. Three groups were defined: certainly infected, probably infected, and non-infected. A total of 12,485 newborns were included, 2151 had PCT measurement, and 26 were infected. Receiver operating curves of PCT determined 0.6 ng/ml as the best cut-off, with an area under the curve of 0.96 (CI 95% 0.95-0.98). Sensitivity, specificity, positive and negative predictive value and positive and negative likelihood ratios were 0.92 (range, 0.75-0.98), 0.97 (0.96-0.98), 0.28 (0.20-0.36), 0.99 (0.99-0.99), 32 (24-41) and 0.08 (0.02-0.3), respectively. Post-test probabilities were 28% (23-33) if the test was positive, and less than 0.001% (0-1.10(-5)) if the test was negative. Gestational age between 28 and 32 weeks (OR 4.4; range, 1.2-16.2) and pH at birth < 7.10 (OR 2.9; 1.1-7.4) were other independent factors of increasing PCT (p < 0.05). PCT measured in umbilical cord blood is reliable to detect early infected and non-infected newborns.

Reopening schools in the context of increasing COVID-19 community transmission: The French experience.

BACKGROUND AND OBJECTIVES: The role of schools in the spread of SARS-CoV-2 infections in the community is still controversial. The objective of our study was to describe the epidemiology of SARS-CoV-2 infections in different pediatric age groups during the first 2 months of the fall back-to-school period, in the context of increasing viral transmission in France. METHODS: Weekly epidemiological data provided by Santé Publique France and the Ministry of National Education were analyzed according to the age groups defined by the different school levels. Weeks (W) 34-42 were considered for analysis. RESULTS: The PCR positivity rate and incidence rate increased in all age groups during the study period, in an age-dependent manner. At W42, with adults being considered as reference, the risk ratio for a positive PCR test was 0.46 [95% CI: 0.44-0.49] and 0.69 [0.68-0.70] for children aged 0-5 years and 6-17 years, respectively. Similarly, the incidence rate ratio was 0.09 [0.08-0.09], 0.31 [0.30-0.32], 0.64 [0.63-0.66], and 1.07 [1.05-1.10] for children aged 0-5 years, 6-10 years, 11-14 years, and 15-17 years, respectively. Children and adolescents accounted for 1.9% of the newly hospitalized patients between W34 and W42, and for 1.3% of new intensive care admissions. No death was observed. Among infected children and adolescents, the percentage of asymptomatic individuals was 57% at W34 and 48% at W42. The number of schools closed remained low, less than 1% throughout the study period. The number of confirmed cases among school staff was consistent with the data measured in the general population. CONCLUSION: In the context of increasing viral transmission in the population, the spread among children and adolescents remained lower than that observed among adults, despite keeping schools open. However, the impact was age-dependent, with data in high schools close to those observed in adults.

Severity of parechovirus infections in infants under 3 months of age and comparison with enterovirus infections: A French retrospective study.

While enteroviruses (EV) are a well-recognized cause of aseptic meningitis in children, human parechoviruses (HPeV), especially genotype 3, have been increasingly reported as a frequent cause of sepsis-like illness and meningitis among young infants. The aim of this study was to describe the epidemiological, clinical, and laboratory characteristics of HPeV infections in infants and to compare them with those of well-known EV infections. This monocentric retrospective study was carried out at the pediatric unit of Nantes University Hospital from January 2015 to August 2018. All patients under 18 years of age with diagnosis codes referring to fever, for whom viral infection was suspected and cerebrospinal fluid (CSF) specimens were collected, were included. All CSF specimens were screened by duplex real-time polymerase chain reaction (PCR) assay that allows for the simultaneous detection of EV and HPeV in clinical samples. During the study period, 1373 CSF specimens from patients under 18 were included. A total of 312 CSF samples were positive for HPeV (n=34) or EV (n=278). Among the 34 HPeV-positive patients, 97% (33/34) were under 3 months of age, whereas the rate was 54% (149/278) for EV-positive patients (P<0.001); thus, patients under 3 months of age were defined as the study population for the rest of this work. A review of the medical records was carried out for the positive cases. In this population, the HPeV detection rate was 5.6% versus 25.3% (P<0.001) for EV. All but one of the HPeV samples available for genotyping were HPeV-3. No seasonality was observed for HPeV infections. Length of hospital stay tended to be longer for children infected with HPeV compared with those infected by EV (3 days vs. 2 days, P=0.05). Clinicians reported more severe illness presentations among HPeV-infected infants, with more frequent administration of fluid bolus (P<0.02). Regarding laboratory characteristics, a significant lack of cellular reaction in the CSF (P=0.004) as well as lower C-reactive protein (CRP) levels (P=0.006) and neutrophil counts (P<0.001) were noted for HPeV infections compared with EV infections. Our results confirm the early onset of HPeV infections (more than 95% of patients aged under 3 months). The clinical presentation and laboratory characteristics of the two infections was similar. However, some higher clinical severity criteria and a lack of CSF pleocytosis were regularly observed in patients with HPeV infections. Considering the significant proportion (5.6%; 95% CI, 3.7-7.5) of all CSF samples in our series, HPeV detection should be systematically included in the microbiological diagnosis of febrile children under 3 months of age.

Investigation of primary immune deficiency after severe bacterial infection in children: A population-based study in western France.

BACKGROUND: Infectious diseases are still an important cause of morbidity and mortality in high-income countries and may preferentially affect predisposed children, especially immunocompromised children. We aimed to evaluate the frequency of recommended immunological tests in children with community-onset severe bacterial infection (COSBI) admitted to a pediatric intensive care unit. We also assessed the frequency and described the typology of diagnosed primary immune deficiency (PID). METHODS: We conducted a retrospective observational epidemiological study in six university hospitals in western France. All children from 1 month to 16 years of age admitted to hospital for bacterial meningitis, purpura fulminans, or meningococcal disease between August 2009 and January 2014 were included. We analyzed the frequency, type, and results of the immunological tests performed on children with meningitis, purpura fulminans, or a meningococcemia episode. RESULTS: Among the 143 children included (144 episodes), 84 (59%) and 60 (41%) had bacterial meningitis and purpura fulminans or meningococcemia, respectively: 72 (50%) had immunological tests and 8% had a complete immunological investigation as recommended. Among the 72 children examined for PID, 11 (15%) had at least one anomaly in the immunological test results. Two children had a diagnosis of PID (one with C2 deficit and the other with C8 deficit) and seven other children had possible PID. Thus, the prevalence of a definite or possible diagnosis of PID was 12% among the children examined. CONCLUSION: PID is rarely investigated after COSBI. We raise awareness of the need for immunological investigations after a severe infection requiring PICU admission.

COVID-19 and schools. Guidelines of the French Pediatric Society.

The educational and social benefits provided by school far outweigh the risks of a possible COVID-19 contamination of children in school environments or in daycare centers. Following summer break, the back-to-school period in France is taking place in the context of an increasing viral spread and requires strict adherence to health measures to limit the risk of outbreaks in communities. Based on a critical update of the role of children in the transmission of the infection, and of children's susceptibility to infection, the French Pediatric Society published practical guidelines for school re-entry and the management of COVID-19 infections in schools.

Epidemiology of invasive early-onset neonatal infection in a French administrative district: A 10-year population-based study.

BACKGROUND: In light of the pending update of the French guidelines for the management of neonatal infections, knowing the current epidemiology of early-onset neonatal infection (EONI) is essential. OBJECTIVES: The aim of this study was to assess the current epidemiology of a French administrative district population of proven EONI, including umbilical cord blood procalcitonin levels. METHODS: We conducted a retrospective population-based study in the Nantes metropolitan area. We included all infants treated for proven EONI in the maternity, neonatology, and intensive care wards between 1 January 2006 and 31 December 2015 in the Nantes University Hospital. RESULTS: Among the 140,502 children born during the study period, 61 cases of EONI were documented. The overall incidence of confirmed EONI was 0.43/1000 live births, with 0.23/1000 GBS (group B streptococcus) infections and 0.08/1000 Escherichia coli infections. The majority of infected newborns were full-term or late-preterm infants (67% were≥34 weeks of gestation), 88% had symptoms of EONI in the first 24h of life, most of which were respiratory. The mortality rate was 8% (in premature infants). Available in 51% of the population, the cord blood PCT value could contribute to an earlier diagnostic screening in 10% of cases but with a very low sensitivity. CONCLUSIONS: The incidence of confirmed EONI is low in this French district. The diagnostic value of PCT umbilical blood cord should be assessed based on further studies before confirming its value. We suggest that a national registry of these rare but serious cases of EONI could contribute to monitoring the epidemiological progression as well as to optimizing our diagnostic and therapeutic strategies.

A 1-year survey of catheter-related infections in a pediatric university hospital: A prospective study.

BACKGROUND: Central venous catheters (CVCs) provide a great comfort for hospitalized children. However, CVCs increase the risk of severe infection. As there are few data regarding pediatric epidemiology of catheter-related infections (CRIs), the main objective of this study was to measure the incidence rate of CRIs in our pediatric university hospital. We also sought to characterize the CRIs and to identify risk factors. MATERIALS AND METHODS: We conducted an epidemiological prospective monocentric study including all CVCs, except Port-a-Caths and arterial catheters, inserted in children from birth to 18 years of age between April 2015 and March 2016 in the pediatric University Hospital of Nantes. Our main focus was the incidence rate of CRIs, defined according to French guidelines, while distinguishing between bloodstream infections (CRBIs) and non-bloodstream infections (CRIWBs). The incidence rate was also described for each pediatric ward. We analyzed the association between infection and potential risk factors using univariate and multivariate analysis by Cox regression. RESULTS: We included 793 CVCs with 60 CRBIs and four CRIWBs. The incidence rate was 4.6/1000 catheter-days, with the highest incidence rate occurring in the neonatal intensive care unit (13.7/1000 catheter-days). Coagulase-negative staphylococci were responsible for 77.5% of the CRIs. Factors independently associated with a higher risk of infection in neonates were invasive ventilation and low gestational age. CONCLUSIONS: The incidence of CRIs in children hospitalized in our institution appears to be higher than the typical rate of CRIs reported in the literature. This was particularly true for neonates. These results should lead us to reinforce preventive measures and antibiotic stewardship but they also raise the difficulty of diagnosing with certainty CRIs in neonates.

Antenatal infection in the rabbit impairs post-natal growth and lung alveolarisation.

Clinical and experimental studies indicate an association between chorioamnionitis and bronchopulmonary dysplasia in preterm infants. The present authors hypothesised that, in the rabbit, antenatal infection may impair lung development after birth, despite effective maternal antibiotic therapy. Pregnant rabbits received an intra-uterine inoculation of 10(3) Escherichia coli colony forming units or vehicle at the end of gestation (day 29). Intravenous ceftriaxone therapy was initiated 8 h after inoculation for a period of 8 days. Pups born between 60 and 84 h after inoculation were kept with their mother until sacrifice on days 0, 1, 5, 8 and 15. Blood cultures from antenatally infected animals were sterile at birth. Postnatal growth was significantly impaired by day 8. Lung morphometry showed a significant decrease of alveolar surface density and interstitial density, with a significant increase of alveolar airspace volume, indicating impaired alveolarisation for the first 2 weeks of postnatal life. Inflammatory and apoptotic processes were not detected in the lung at birth or subsequently. Intra-uterine infection in rabbits is, therefore, responsible for concomitant postnatal growth retardation and abnormal pulmonary development despite early and effective antenatal antibiotic therapy. This may constitute an alternative model to study the consequences of antenatal infection on postnatal growth and lung development.

[Distribution of neutralizing measles serum antibodies according to age in women of childbearing age in France in 2005-2006]. / Distribution en fonction de l'âge de la concentration sérique des anticorps neutralisants antirougeole chez les femmes en âge de procréer en France en 2005-2006.

UNLABELLED: Measles-vaccine coverage (MVC) increased significantly only beginning in 1983 based on the official recommendations. The majority of women born after 1983 should have vaccine-acquired rather than naturally derived immunity. Passively transferred measles antibodies (Mab) are expected to provide protection to offsprings during their 1st few months of life. OBJECTIVE: Compare neutralizing Mab titers according to age in women aged 12-40 years, i.e., born before and after 1983. METHODS: A multicenter seroepidemiological study was conducted in France in 2005-2006; 210 outpatient or hospitalized women were enrolled and classified into 4 age groups (12-18, 19-22, 23-30, and 31-40 years). Mab titers were assessed using a reference plaque reduction neutralization assay (protection threshold > 120 mIU/ml). RESULTS: Ninety-four percent of subjects had a Mabs titer greater than 120 mIU/ml. Women born before 1983 had significantly higher geometric mean titers (GMTs) of Mabs than those born after 1983(1358 mIU/ml vs. 731 mIU/ml [p<0.001]). The comparison of the 4 cohorts showed a significant decrease (p<0.001) in GMTs of Mab in the female population with increasing age (670, 771, 1173, and 1821 mUI/ml, respectively, in the 12-18, 19-22, 23-30, and 31-40 years age groups). For the 1st time in France, we show in women of childbearing age that in 2005-2006 neutralizing Mab GMTs were far above protective threshold for all age groups. Women in younger age groups (with high MVC) have significantly lower Mab titers. A lower passive transfer of Mab to their offsprings could result in a shorter period of measles protection and question the measles vaccine 1st dose at 1 year.

A prospective observational study of medication errors in a pediatric emergency department.

We present a prospective, observational study evaluating the incidence of medication errors (ME) in a university hospital pediatric emergency department and describe their characteristics and determinants. A systematic analysis of the handwritten prescriptions was conducted by a clinician and pharmacist. Of 11,573 consecutively studied prescriptions in children under 15 years of age, the ME incidence was 0.9% (n=102). The incidence of errors found was statistically significantly higher in children older than 5 years (OR=2.05; P=0.026). There was no significant difference regarding the time of admission (P=0.544), the day of the week (P=0.940), or the affluence of people in attendance at the emergency department. The errors observed were all prescription errors. Most errors were related to analgesic (51%) and antibiotic (30%) treatments. No serious errors were reported. CONCLUSION: We found a low incidence of medication errors in this study. The validation of prescriptions by a senior multidisciplinary staff could contribute to limited medication errors. Measures should be continued to further reduce the incidence of drug errors by calling the attention of prescribers to the most common situations at risk of ME.

Currarino syndrome as an etiology of a neonatal Escherichia coli meningitis.

We report the case of a 29-day-old baby girl in whom Escherichia coli meningitis led to the diagnosis of Currarino syndrome (CS) (OMIM 176450), an autosomal-dominant genetic disorder associated with sacral agenesis, anorectal malformation, presacral masses and spinal cord malformations. Her condition improved with antibiotics and early surgical treatment. A familial study identified other genetically related individuals with similar symptoms.

Almond oil implicated in a Staphylococcus capitis outbreak in a neonatal intensive care unit.

OBJECTIVE: To develop an effective outbreak-control strategy by identifying the source and modes of transmission of Staphylococcus capitis in a 60-bed neonatal intensive care unit (NICU). STUDY DESIGN: We conducted a study among neonates hospitalized during the outbreak (June 2000 through November 2003). All cases of S. capitis colonization or infection detected by clinical samples during the outbreak were included. The molecular analysis of the isolated was assessed by pulsed-field electrophoresis. We reported the description of the outbreak and the measures taken during this investigation. RESULT: Thirty-three patients were colonized or infected by S. capitis. Mean gestational age was 28.5+/-4.4 weeks of gestation, mean birth weight was 1068+/-637.3 g and the mean length of hospital stay was 77.9+/-35.9 days. We observed that positive S. capitis cultures were over-represented in six beds of the NICU. Because S. capitis is known to thrive in lipid media, we cultured samples from the almond oil bottles assigned to these beds. S. capitis strain recovered from one of the almond oil sample was genetically identical to the strain recovered from the cases. CONCLUSION: Almond oil is an unusual reservoir infection. Control policy allowed prompt institution of measures that were successful in ending the outbreak.
