Identifying Newborns with Hypoxic-Ischemic Encephalopathy in Hospital Discharge Data: A Validation Study.

Hospital discharge databases (HDDs) are increasingly used for research on health of newborns. Linkage between a French population-based cohort of newborns with hypoxic-ischemic encephalopathy (HIE) and national HDD showed that the HIE ICD-10 code was not accurately reported. Our results suggest that HDD should not be used for research on neonatal HIE without prior validation of HIE ICD-10 codes.

2017 French health authority guidelines for neonates at risk of early-onset sepsis: Adherence and barriers in a tertiary hospital.

The objective of this study was to evaluate the adherence to the French Health Authority's 2017 guidelines concerning early-onset sepsis (EOS) in neonates. This 6-month prospective observational study was conducted in 2020 in a tertiary hospital maternity unit. Neonates were classified according to their risk of EOS and the level of appropriate surveillance was analyzed. The risk of EOS was determined for 69.9% of the 1024 included neonates. Of the 123 neonates with a moderate or high risk of EOS, the optimal clinical surveillance was 88%. Even in a tertiary hospital, with training of caregivers, adherence to guidelines was incomplete. Some corrective measures are suggested and should be applied to enhance the adherence.

Respiratory distress management in moderate and late preterm infants: The NEOBS Study.

OBJECTIVE: To investigate the characteristics and management of respiratory failure (RF) in moderate-to-late preterm infants. METHODS: NEOBS was a prospective, multicenter, observational study conducted in 46 neonatal intensive care units caring for preterm infants (30+0/7 to 36+6/7 weeks of gestation [WG]) in France in 2018. The cohort was stratified into two groups: 30-33 WG (group 1) and 34-36 WG (group 2). Infants with early neonatal RF were included and the outcomes assessed were maternal, pregnancy, and delivery characteristics and how RF was managed. RESULTS: Of the 560 infants analyzed, 279 were in group 1 and 281 were in group 2. Most pregnancies were singleton (64.1%), and 67.4% of women received prenatal corticosteroids (mostly two doses). Infants were delivered by cesarean section in 59.6% of cases; 91.7% of the infants had an Apgar score ≥7 at 5min. More than 90% of infants were hospitalized post-birth (median duration, 36 and 15 days for groups 1 and 2, respectively). Medical intervention was required for 95.7% and 90.4% of the infants in group 1 and group 2, respectively, and included noninvasive ventilation (continuous positive airway pressure [CPAP]: 88.5% and 82.9%; high-flow nasal cannula: 55.0% and 44.7%, or other) and invasive ventilation (19.7% and 13.2%). The two main diagnoses of RF were respiratory distress syndrome (39.8%) and transient tachypnea of the newborn (57.3%). Surfactant was administered to 22.5% of the infants, using the less invasive surfactant administration (LISA) method for 34.4% of the patients. In the overall population, 8.6% of the infants had respiratory and/or hemodynamic complications. CONCLUSIONS: The NEOBS study demonstrated that CPAP was widely used in the delivery room and the LISA method was chosen for 34.4% of the surfactant administrations for the management of RF in moderate-to-late preterm infants. The incidence of RF-related complications was low.

Neurodevelopmental impairment at 2 years of age in children born before 29 weeks' gestation with bronchopulmonary dysplasia.

INTRODUCTION: Very preterm children are at a high risk for neurological impairment, especially those with bronchopulmonary dysplasia (BPD). The main goal of this study was to describe the neurodevelopmental impairment (NDI) at 2 years of corrected age in children born before 29 weeks' gestation between 2010 and 2015 and affected by BPD at 28 days of life. We also searched for risk factors associated with NDI, especially postnatal steroid (PNS) administration. MATERIAL AND METHODS: This was a retrospective study comprising a cohort of children hospitalized at the university hospital in Grenoble, born before 29 weeks' gestation between 2010 and 2015, and included in the monitoring network "Naitre et Devenir" (RND). Infants at 2 years of corrected age were classified as having NDI if they had at least one of the following outcomes: a global developmental quotient (DQ) on the revised Brunet-Lézine scale of<85, blindness, deafness, or cerebral palsy (CP) graded as level 3 or more according to the Gross Motor Function Classification System. RESULTS: A total of 129 children were included, of whom 99 were monitored at the age of 2 years: 31.3% of the population had NDI and 4% had CP. The median DQ test result was 90 (interquartile 82-97). Factors associated with NDI in univariate analysis were low gestational age, low birth weight, a cord pH<7.2, chorioamnionitis, treatment for persistent ductus arteriosus, longer oxygen therapy, and outborn status, which almost reached statistical significance. In multivariate analysis, low gestational age and outborn status remained statistically significant, while chorioamnionitis was found to have some association with NDI. While 13.1% of the followed-up population was treated with PNS, this risk factor was not associated with NDI. CONCLUSION: In a population of very preterm children, one third had NDI at 2 years of corrected age. Low gestational age, outborn status, and perinatal inflammation are associated with this unfavorable outcome. The frequency of sequelae confirms the importance of following up these children.

Has the introduction of high-flow nasal cannula modified the clinical characteristics and outcomes of infants with bronchiolitis admitted to pediatric intensive care units? A retrospective study.

BACKGROUND: This study aimed to assess how the emergence of high-flow nasal cannula (HFNC) has modified the demographic and clinical characteristics as well as outcomes of infants with bronchiolitis admitted to a pediatric intensive care unit (PICU). METHODS: This was a single-center retrospective study including infants aged 1 day to 6 months with bronchiolitis requiring HFNC, noninvasive ventilation (NIV), or invasive ventilation on admission. RESULTS: A total of 252 infants (mean age 53±36 days) were included in the study. The use of HFNC increased from 18 (21.4%) during 2013-2014 to 53 infants (55.2%) during 2015-2016. The length of stay in the PICU decreased over time from 4.7±2.9 to 3.5±2.7 days (P<0.01) but the hospital length of stay remained similar (P=0.17). On admission, patients supported by HFNC as the first-line therapy were older. The PICU length of stay was similar according to the type of respiratory support (P=0.16), but the hospital length of stay was longer for patients supported by HFNC (P=0.01). CONCLUSION: The distribution of respiratory support has significantly changed over time for patients with bronchiolitis and HFNC is increasingly used. The demographic and clinical characteristics of the have not changed over time. However, the PICU length of stay decreased significantly.

[Propositions for perinatal care at extremely low gestational ages - Working group on "Extremely low gestational ages" for SFMP, CNGOF, and SFN]. / Propositions sur la prise en charge en cas d'extrême prématurité ­ Le groupe de travail « Extrême Prématurité ¼ pour la SFMP, le CNGOF et la SFN.

OBJECTIVES: International literature suggests that active perinatal management at extremely low gestational ages improves survival without increasing the risk of impairment in survivors, compared to less active management. Although these results are limited to a small number of countries, they question current practices in France. New propositions on perinatal management of extremely preterm infants have carried out by the French Society of Perinatal Medicine, the French Society of Neonatology and the National College of French Obstetricians and Gynecologists. METHODS: This group was set up in 2015 on the initiative of the professional societies and in collaboration with parents' and users' associations. The work was based on a review of the literature on the prognosis of extremely preterm children, as well as on recommendations by European societies. Based on this information, a text was produced, submitted to all members of the working group and definitively validated in April 2019. RESULTS: This text offers a decision-making guideline for the management at extremely low gestational ages. Its principles are: the administration of steroids independently of management (resuscitation or comfort care); a prognostic evaluation and a collegial decision, outside the context of the emergency; a consensus on the information to be given to parents before going to inform them and gather their opinion. CONCLUSIONS: These new propositions will contribute to modifying perinatal care at extremely low gestational ages in France.

[Neuroprotection with hypothermia for hypoxic ischemic encephalopathy in term newborn: review of the learning]. / Neuroprotection par hypothermie lors des encéphalopathies anoxo-ischémiques du nouveau-né à terme: état des connaissances.

The hypothermia treatment for neonatal hypoxic ischemic encephalopathy is a concept revisited for more than 10 years. With this strategy, animal studies have shown an 80% reduction of brain damage. Conditions for the practice of hypothermia, to obtain neuroprotection, have been described in these studies: rapidity of the onset of cooling after the hypoxic ischemic event, prolonged duration during several hours, ability to obtain neuroprotection with two methods of cooling, selective head cooling or whole body hypothermia. Pilot studies in human newborns have demonstrated the feasibility of these strategies without immediate adverse effects. Two large randomised trials have been conducted in 2005 to test the efficacy. Only with the strategy of whole body cooling, the incidence of poor outcome at 18 months (death or severe disability) was statistically decreased (44% versus 66% in the control group). This reduction seems especially significant in the sub group of intermediate severity (48% versus 66%), whereas severe forms (Grade III in the Sarnat and Sarnat classification) were probably not ameliorated with this treatment. Now, the major problem is to determine the best indications for hypothermia with an early and precise assessment of the grade of the encephalopathy.

Neonatal fever: A puzzling case.

Toxoplasmosis is a potentially serious fetal infection associated with maternal seroconversion of toxoplasmosis during pregnancy. Follow-up and treatment vary between different countries. We present a case of congenital toxoplasmosis with unusual physiopathology and symptomatology. The mother was immunized before the beginning of pregnancy but immunosuppressive treatments for Crohn disease maintained during the pregnancy could explain toxoplasmosis reactivation in the mother and congenital toxoplasmosis. The baby presented reversible B lymphopenia and hypogammaglobulinemia.

A neonatal specialist with recurrent methicillin-resistant Staphylococcus aureus (MRSA) carriage implicated in the transmission of MRSA to newborns.

This study reports an investigation of outbreaks of methicillin-resistant Staphylococcus aureus (MRSA) infection and colonization involving 17 newborns in the neonatal unit of a teaching hospital. A neonatal specialist colonized with MRSA that eventually became mupirocin-resistant was implicated as a recurrent source of transmission of MRSA to newborns.

[Neonatal splenic injury: a difficult diagnosis]. / La rupture splénique en période néonatale: un diagnostic difficile.

Neonatal splenic injury is a rare but serious condition, due to the risk of haemorrhagic shock. We report on the case of a newborn infant with a neonatal respiratory distress that first evoked materno-fetal infection. Clinical deterioration, with anemia and abdominal distension, led then to the proper diagnosis. Dystocia seems to be the most likely cause of the splenic rupture in this report. Medical treatment is advocated as first line, while surgical treatment may be necessary in some cases. In the case surgery is inevitable, a conservative approach is preferable.

[Information in perinatal medicine: ethical aspects]. / L'information dans le contexte du soin périnatal: aspects éthiques.

Besides the undeniable need to respect parental autonomy, providing information is a legal and moral obligation, to be informed a basic right. The act of informing should be considered as an exchange and necessarily begins by listening to the other. According to the jurisprudence of the Court of Cassation that draws on Article 35 of the Deontological Code, information has to be clear (implying an educational effort, availability and to check that the information has been well understood), appropriate (adapted to each situation and person) and honest (which supposes a moral contract between parents and physicians). Loyalty implies a consideration of the uncertainty underlying medical practice, and of the limitations in arriving at a prognosis. Indeed, caution needs to be exercised in conveying information, taking into account the risk of its becoming self-fulfilling, which could modify the way in which parents take care of their child. The information given has to be coherent, both within the spatial dimension (coherence of information between the different maternity services in the perinatal network) and the temporal dimension (coherence of information between pre- and postnatal stages). It must be acknowledged that information is essentially subjective. There is a fundamental difference between coherence and uniformity, and as regards information, uniformity is neither possible nor desirable. In each situation, priority must be given to oral information delivered in an appropriate material context. The principle of establishing, in the medical file, a written trace of the information given at various stages is one way to guarantee its coherence.

Early antithrombotic treatment with warfarin oral suspension in severe neonatal protein C deficiency.

Neonatal severe protein C deficiency is a serious disease. There is no uniform approach for long-term preventive treatment of thrombotic events. We report the case of neonatal severe protein C deficiency treated with warfarin oral suspension. An international normalized ratio (INR) from 2.5 to 3.5 was expected. The INR was measured by home monitoring using the Coaguchek XS® (Roche Diagnostics, Mannheim, Germany) monitor. During 2years of warfarin treatment, there were only two minor episodes of purpuric access and no bleeding was reported. This case suggests that the early introduction of warfarin oral suspension, home-care monitoring, and parental education programs may be a beneficial treatment option for children with protein C deficiency.

[Neonatal hyperthyroidism: A sometimes challenging diagnosis]. / L'hyperthyroïdie néonatale : un diagnostic parfois difficile.

Graves disease complicates two pregnancies out of 1000 and when it is known before pregnancy, it warrants careful monitoring of the fetus and the newborn. We report on a case of neonatal hyperthyroidism, which revealed a previously unknown maternal thyroid disease. In this situation, neonatal signs can be misinterpreted, delaying the diagnosis. Neonatal hyperthyroidism is, however, a therapeutic emergency because of the risk of cardiac and neurological complications. The neonatologist must identify thyroid disease in the absence of a maternal history in order to promptly start therapy.

[Acute epiglottitis due to Haemophilus influenzae b: A severe consequence of increased skepticism about vaccination]. / Épiglottite aiguë à Haemophilus influenzae b : conséquence grave du scepticisme vaccinal.

Acute epiglottis is a life-threatening disease in relation with the occurrence of an acute upper airway obstruction. Its incidence has fallen dramatically since the widespread introduction of Haemophilus influenzae type b (Hib) conjugate vaccine. We report the case of a 26-month-old child who was not fully immunized and presented acute upper airway respiratory distress with fever. The symptoms quickly evolved to a respiratory arrest condition with bradycardia, revealing epiglottitis due to Hib. Despite high immunization coverage with great efficacy and occurrence of herd immunity, this entity still exists because of the French population's skepticism of the routine vaccination schedule.

[Teaching pediatrics to residents via conventional lectures in France: A national survey from students]. / Enseignement théorique du Diplôme d'études spécialisées de pédiatrie en France : évaluation nationale par les internes.

OBJECTIVE: To assess the point of view of young physicians training in pediatrics in France on their theoretical courses during residency. METHODS: A free-access electronic anonymous survey was sent three times by e-mail to the 1215 residents in pediatrics, from July to October 2015. RESULTS: Fifty-seven percent of French residents in pediatrics responded to the survey. It was established that they took part in six (range, 3-10) half-days of specific theoretical teaching in pediatrics from November 2014 to mid-April 2015. Only 54% participated in more than 75% of regional theoretical training. The main self-declared reason for their absence was that they could not leave their clinical activities. Fifty-three per cent of the residents took part in additional training, 45% of them because they found the primary theoretical training insufficient. The overall quality of the theoretical teaching was rated 5 (range, 3-7) out of 10. Eighty-five percent of residents expected to be evaluated on their knowledge during their residency. CONCLUSION: In pediatrics, additional training is individually undertaken because they deemed their initial training insufficient during their residency. An evaluation of knowledge is requested by residents. The reform of the national residency program must take into account these results in redesigning the theoretical training in pediatrics, integrating innovative teaching techniques to daily practice, for example.

[Neonatal arterial ischemic stroke: Review of the current guidelines]. / Accidents vasculaires cérébraux ischémiques artériels néonatals : synthèse des recommandations.

Neonatal arterial ischemic stroke (NAIS) is a rare event that occurs in approximately one in 5000 term or close-to-term infants. Most affected infants will present with seizures. Although a well-recognized clinical entity, many questions remain regarding diagnosis, risk factors, treatment, and follow-up modalities. In the absence of a known pathophysiological mechanism and lack of evidence-based guidelines, only supportive care is currently provided. To address these issues, a French national committee set up by the French Neonatal Society (Société française de néonatologie) and the national referral center (Centre national de référence) for arterial ischemic stroke in children drew up guidelines based on an HAS (Haute Autorité de santé [HAS]; French national authority for health) methodology. The main findings and recommendations established by the study group are: (1) among the risk factors, male sex, primiparity, caesarean section, perinatal hypoxia, and fetal/neonatal infection (mainly bacterial meningitis) seem to be the most frequent. As for guidelines, the study group recommends the following: (1) the transfer of neonates with suspected NAIS to a neonatal intensive care unit with available equipment to establish a reliable diagnosis with MRI imaging and neurophysiological monitoring, preferably by continuous video EEG; (2) acute treatment of suspected infection or other life-threatening processes should be addressed immediately by the primary medical team. Persistent seizures should be treated with a loading dose of phenobarbital 20mg/kg i.v.; (3) MRI of the brain is considered optimal for the diagnosis of NAIS. Diffusion-weighted imaging with apparent diffusion coefficient is considered the most sensitive measure for identifying infarct in the neonatal brain. The location and extent of the lesions are best assessed between 2 and 4 days after the onset of stroke; (4) routine testing for thrombophilia (AT, PC PS deficiency, FV Leiden or FII20210A) or for detecting other biological risk factors such as antiphospholipid antibodies, high FVIII, homocysteinemia, the Lp(a) test, the MTHFR thermolabile variant should not be considered in neonates with NAIS. Testing for FV Leiden can be performed only in case of a documented family history of venous thromboembolic disease. Testing neonates for the presence of antiphospholipid antibodies should be considered only in case of clinical events arguing in favor of antiphospholipid syndrome in the mother; (5) unlike childhood arterial ischemic stroke, NAIS has a low 5-year recurrence rate (approximately 1 %), except in those children with congenital heart disease or multiple genetic thrombophilia. Therefore, initiation of anticoagulation or antithrombotic agents, including heparin products, is not recommended in the newborn without identifiable risk factors; (6) the study group recommends that in case of delayed motor milestones or early handedness, multidisciplinary rehabilitation is recommended as early as possible. Newborns should have physical therapy evaluation and ongoing outpatient follow-up. Given the risk of later-onset cognitive, language, and behavioral disabilities, neuropsychological testing in preschool and at school age is highly recommended.

Fetal lung volume in congenital diaphragmatic hernia.

In a retrospective study of 22 neonates with congenital diaphragmatic hernia, fetal lung volume (FLV) measured by magnetic resonance imaging was associated with survival; the best FLV ratio cut-off to predict mortality was 30% of expected FLV. This study supports a correlation between FLV and the chances of survival.

[Pseudo-"isolated" intestinal perforation in a very low birth weight infant: exceptional presentation of Hirschsprung's disease]. / Perforation intestinale du grand prématuré en apparence "isolée": mode de révélation exceptionnel de la maladie de Hirschsprung.

Intestinal perforations in preterm newborn are characterized with high morbidity and mortality rates. They often are associated with necrotizing enterocolitis and seldom correspond to idiopathic spontaneous intestinal perforation. Perforations upstream of an intestinal organic obstruction (atresia), or of a functionnal obstruction (meconium-ileus, Hirschsprung disease) have been considered to be rare in preterm newborns. We report a case of caecal perforation with a pneumoperitoneum which occurred at 5 days of life, in a 28-week gestational age infant, that was treated by cecostomy. There were no signs of necrotizing enterocolitis. At 43 days of life, the preoperative contrast enema study revealed a left colon transition zone, suggesting a Hirschsprung disease, which was confirmed by rectal biopsies. Transanal pull-through was performed. There were no postoperative complication. This case demonstrates that an isolated intestinal perforation in very preterm newborn can reveal a Hirschsprung disease, especially if it occurs in the caecum.

[Osteomyelitis in cat scratch disease: A case report and literature review]. / À propos d'un cas d'ostéomyélite de la maladie des griffes du chat.

INTRODUCTION: Cat scratch disease is an infection caused by Bartonella henselae. The main clinical form is a lymphadenopathy with fever. However, uncommon bone involvement has been described. CASE REPORT: In this paper, we report a case of osteomyelitis in a 13-year-old teenager infected with B. henselae. The diagnosis was made based on PCR only because the serology was negative. A literature review reports 65 cases of osteomyelitis due to cat scratch disease. For each case, serology and PCR were notified. CONCLUSION: Osteomyelitis caused by B. henselae is a rare clinical manifestation. The diagnosis can be difficult, but the medical history must be accurate to search for contact with a cat and a cat scratch.
