Hypothermia for neonatal hypoxic-ischemic encephalopathy: Retrospective descriptive study of features associated with poor outcome.

AIM: To investigate the clinical, laboratory, electrophysiological, and imaging features associated with death or neurological impairment at 1 year of age in term neonates with hypoxic-ischemic encephalopathy (HIE) treated by therapeutic hypothermia (TH). METHODS: This was a single-center retrospective and descriptive study conducted over a period of 2 years. We included consecutive term newborns with moderate or severe HIE who were treated by TH initiated within the sixth hour after birth and continued for 72 h,. For all patients, brain magnetic resonance imaging (MRI) was performed before the eighth day and a score was established; furthermore, at least two electroencephalograms were recorded. RESULTS: Among the 33 patients included, 20 neonates had a favorable outcome and 13 had an unfavorable outcome. Early clinical seizures (15% vs. 53.8%, p = 0.047), the persistence of a poor prognosis according to the electroencephalogram pattern after TH (0% vs. 69.2%, p = 0.0001), and an elevated score on the early brain MRI (2 vs. 11, p < 0.001) combined with a high lactate/N-acetyl-aspartate ratio (0.52 vs. 1.33, p = 0.008) on spectroscopy were associated with death and a poor outcome. CONCLUSION: A combination of tools can help the medical team to establish the most reliable prognosis for these full-term neonates, to guide care, and to inform parents most appropriately and sincerely.

Withholding and withdrawing treatment in pediatric intensive care. Update of the GFRUP recommendations.

In 2005, the French-speaking task force on pediatric critical and emergency care [Groupe Francophone de Réanimation et d'Urgences Pédiatriques (GFRUP)] issued recommendations on withholding and withdrawing treatments in pediatric critical care. Since then, the French Public Health Code, modified by the laws passed in 2005 and 2016 and by their enactment decrees, has established a legal framework for practice. Now, 15 years later, an update of these recommendations was needed to factor in the experience acquired by healthcare teams, new questions raised by practice surveys, the recommendations issued in the interval, the changes in legislation, and a few legal precedents. The objective of this article is to help pediatric critical care teams find the closest possible compromise between the ethical principles guiding the care offered to the child and the family and compliance with current regulations and laws.

Surgical management of neuroblastoma-related hepatomegaly: do material and method really count?

The authors report 2 cases of neuroblastoma-associated hepatomegaly, which were treated using a Silastic patch, and discuss in the light of recent reports, the technical aspects and outcome of these children. They were satisfied by the decompression achieved with the patch and believe there is no increased risk in using Silastic rather than other types of material. The outcome for these children depends more on the evolution of the underlying disease than the technical aspects of the abdominal decompression.

[Vaccine prevention in perinatal health care: parents, children and professionals]. / Vaccination en périnatalité : parents, enfants, professionnels.

Recent legislative texts have changed vaccinal policy and reinforced the role of midwives in vaccine prevention in perinatal healthcare. Quite as paediatricians and obstetricians-gynecologists, midwives can now prescribe and carry out, for the mothers, vaccines against rubella, tetanus, poliomyelitis, diphtheria, hepatitis B, influenza and whooping-cough and for the newborns vaccines against hepatitis B and tuberculosis. Concerning vaccinations, practitioners have to respect the vaccination calendar and a collaborative action is useful and necessary. These national guidelines are regularly updated when new vaccines and new recommendations come to light, for example for children (papillomavirus, tuberculosis, pneumococcus...), young adults (varicella, whooping-cough) and health professions in contact with very young children (varicella, measles, influenza and whooping-cough). The recent changes in tuberculosis prevention from routine vaccination of all newborn infants to selective vaccination lead to reinforce measures to detect the infants at higher risk, for them to be vaccinated before discharge at home. Midwives and nurses occupy a central place in family policy and become, with obstetricians-gynecologists and pediatricians, key actors for the effectiveness and the success of vaccine strategies in perinatal health.

[Prognostic value of MR in term neonates with neonatal hypoxic-ischemic encephalopath: MRI score and spectroscopy. About 26 cases]. / Apport pronostique de la résonance magnétique cérébrale dans l'encéphalopathie hypoxique-ischémique du nouveau-né à terme: score d'imagerie, spectroscopie. Etude de 26 cas.

UNLABELLED: Neonatal hypoxic-ischemic encephalopathy remains a major cause of chronic disability in childhood. Early diagnosis and prognosis are necessary for the clinician to adapt the treatment. However, there is yet no reliable test to predict the patient's evolution. OBJECTIVE: The aim of our study was to evaluate the predictive value of a personal magnetic resonance imaging (MRI) scoring system and of magnetic resonance spectroscopy (MRS). MATERIAL AND METHODS: We included 26 term newborns in condition of neonatal brain suffering. MR examination was performed during the first week of life for all patients and MRI and MRS data were collected. Standardised follow-up visits were made for all patients. Finally, prognostic value of the different criteria was evaluated with statistical tests. RESULTS: Our MRI scoring system proved to be linked to prognosis. A high MRI score, abnormal signal in the internal capsule, white matter or basal ganglia abnormalities with diffusion imaging were associated with unfavourable outcome. These results confirmed the data of the literature concerning the MRI predictive value. Our study also confirmed prognostic interest of MR: particularly, ratios using lactate were significantly linked to prognosis in our study. Specificity of the elevation of these ratios was interesting but sensibility was less optimal. CONCLUSION: We suggest using our MRI scoring system which associates standard MRI and diffusion imaging, which is significantly related to outcome. We confirm the prognostic value of MRS in this pathological situation. MR with diffusion sequence and spectroscopy, performed three to four days after birth appears to be an essential tool to manage these patients.

[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.

[Acute respiratory distress syndrome in childhood: Changing definition and news from the Pediatric Consensus Conference]. / Syndrome de détresse respiratoire aiguë de l'enfant : évolution de la définition et nouveautés de la conférence de consensus pédiatrique.

Acute respiratory distress syndrome (ARDS) is a rapidly progressive hypoxemic respiratory insufficiency induced by alveolar filling mainly caused by alveolocapillary wall disruption, following direct or indirect pulmonary injury. Much less frequent in children than in adults, pediatric intensivists had long applied adult guidelines to their daily practice. In 2015, experts from the Pediatric Acute Lung Injury Consensus Conference (PALICC) published the first international guidelines specifically dedicated to pediatric ARDS. After a short summary of the history of the ARDS definition since its first report in 1967, we describe the main diagnostic and therapeutic guidelines for PALICC.

[Clinical features of Pseudomonas aeruginosa infections]. / Aspects cliniques de l'infection a Pseudomonas aeruginosa.

Pseudomonas aeruginosa is a ubiquitous environmental organism usually considered as opportunistic pathogen in immunocompromised subjects. However it can produce disease in healthy children, mainly on moist body sites. Familial, community and nosocomial outbreaks of cutaneous infections have been reported. Ecthyma gangrenosum is possible without bacteremia. P. aeruginosa is also the most common cause of otitis externa in swimmers and osteomyelitis after puncture wound of the foot.

[Central catheters and pericardial effusion: results of a multicentric retrospective study]. / Cathéters centraux et épanchements péricardiques en période néonatale: étude rétrospective multicentrique.

OBJECTIVE: To evaluate the use of neonatal central venous catheters (CVC) in 38 french neonatal units and occurrence of pericardial effusion (PCE) over the past 5 years. MATERIALS AND METHODS: We surveyed 38 units with a questionnaire and studied the cases of PCE in five units. RESULTS: Response rate was 89% (34/38). Accepted CVC tip positions were: junction of right atrium (RA) and vena cava (VC) 76%, VC 58%, RA 11%. Fifty percent of the centers had been exposed to PCE. 16 cases of PCE were studied. Median gestational age was 31 weeks (range: 26.1 to 40 weeks). Median time from insertion: 3.2 days (range: 0.4-13.5). In all cases CVC tip was intracardiac at insertion with inadequate withdrawing in 13 cases. Sudden cardiac collapse was reported in eight cases, and unexplained cardiorespiratory instability in six cases. Echography showed PCE in 14 cases. One diagnosis was post-mortem. CVC was withdrawn in 12 patients and 13 underwent pericardiocentesis. Four patients died and two had neurological sequelae. CONCLUSION: PCE was associated with intracardiac CVC tip. The CVC tip should be controlled with radiography or echography outside the cardiac silhouette. PCE diagnosis must be considered in face of unexplained cardiovascular decompensation of neonate with CVC.

[Rehospitalization of very preterm infants in the first year of life. Comparison of 2 groups: 1997 and 2002]. / Réhospitalisation dans l'année suivant leur naissance des prématurés d'âge gestationnel inférieur ou égal à 32 semaines d'aménorrhée. Comparaison de 2 cohortes: 1997 et 2002.

OBJECTIVE: The aim of the study was to compare the rehospitalization rate in the first year of life between 2 groups of very preterm infants born on 1997 and 2002; then we compared the very preterm infants' rehospitalization rate between our retrospective 1997 group and literature (including French cohort Epipage). PATIENTS AND METHODS: Our retrospective study included all neonates born

Congenital idiopathic chylothorax in neonates: chemical pleurodesis with povidone-iodine (Betadine).

Chylothorax is defined as an accumulation of chyle in the pleural space. This condition usually occurs after an operation, the congenital idiopathic form being rare (1/15000 births). Recovery is observed within four to six weeks of diagnosis in most cases. Treatment is either conservative or surgical. Four cases are reported of congenital chylothorax (three idiopathic, one accompanied by diffuse lymphangectasia) managed by chemical pleurodesis (intrapleural injection of povidone-iodine). Tolerance was satisfactory: unaltered thyroid function in the three cases explored; one case of transient generalised oedema. Treatment was deemed successful in three of the four cases. One child died from renal failure (unrelated to the chemical pleurodesis). Pleurodesis by povidone-iodine appears to be well tolerated and may represent a good alternative to mechanical abrasion or surgery for congenital idiopathic chylothorax. Its use for refractory chylothorax may also decrease the morbidity related to prolonged hospital stay.

Schizencephaly: clinical and imaging features in 30 infantile cases.

Schizencephaly is an uncommon structural disorder of cerebral cortical development, characterized by congenital clefts spanning the cerebral hemispheres from the pial surface to the lateral ventricles and lined by cortical gray matter. Either an antenatal environmental incident or a genetic origin could be responsible for this lesion which occurs between the third and fourth month of gestation. We report the clinical and cranial imaging features of 30 children, of whom 15 had unilateral and 15 had bilateral lesions. Their ages at the time of the first presentation ranged from 1 month to 10 years. They were thoroughly studied from clinical, epileptical, imaging and electroencephalographic (EEG) viewpoints. Five patients were investigated by cranial computed tomography (CT), eight by cranial magnetic resonance (MR) imaging, and 17 by both methods. The clinical features consisted of mild hemiparesis in 17 cases (57%), 12/17 were related to a unilateral phenotype (80% of all unilateral forms) and 5/17 to a bilateral phenotype. A tetraparesis was present in nine cases, all of which were due to a bilateral cleft. Bilateral forms were significantly associated with tetraparesis, whereas unilateral forms were associated with hemiparesis. Mental retardation was observed in 17 cases (57%), and was observed significantly more often in bilateral clefts (80%). When both hemispheres are involved, an absence of reorganization of the brain function between the two hemispheres leads to severe mental deficits, in addition to the cerebral anomaly itself. Eleven patients had seizures (seven from unilateral and three from bilateral forms). The degree of malformation was not related to the severity of epilepsy. Migration disorders, such as dysplasia or heterotopia, were observed in 30% of cases and are also important etiopathogenetic factors. The septum pellucidum was absent in 13 cases (43%), with septo-optical dysplasia in two cases. Corpus callosum dysgenesis was noted in 30% of cases. Four cases of mega cisterna magna were noted. Although familial cases and environmental factors have been previously reported, schizencephaly appears to be, in the majority of cases, sporadic.

[Persistence of point-waves in the encephalogram (EEG) in idiopathic generalized epilepsy and therapeutic decisions]. / Persistance de pointes-ondes sur l'électroencéphalogramme (EEG) dans les épilepsies généralisées idiopathiques et décisions thérapeutiques.

We reviewed the literature on the following issues in idiopathic generalized epilepsy, is there a correlation between the persistence of seizures and electroencephalographic anomalies? Do point-waves observed in well-controlled patients constitute a factor predicting relapse? Do changes in paroxysmal anomalies during the disease course mean poor prognosis? Actually, there is very little literature on these issues and some disagreement in those data which have been published. Documented studies have been conducted in search of factors predicting relapse at treatment withdrawal, but little has been published concerning the role of the EEG. Few studies specifically mention idiopathic generalized epilepsy. In terms of the syndrome studied, they concern heterogeneous groups of patients. Generally, it is accepted that the EEG helps predict clinical course in idiopathic generalized epilepsy as it does in other epilepsies, given the characteristic EEG signs. This is true in patients under treatment and after treatment withdrawal. Risk errors were not however reported. II would appear reasonable to assume that no one EEG anomaly is determinant outside the clinical context.

[Multiple sclerosis: pathogenesis and manifestations in children]. / Sclérose en plaques: pathogénie et formes de révélation chez l'enfant.

Multiple sclerosis (MS) is rare in children and occurs exceptionally before ten years. Sex ratio (girl/boy) is around 2.5 to 3, higher than in adults. Brain stem dysfunction and meningeal symptoms are more commonly first manifestations of the disease than in adults. Optic neuritis is also a frequent early manifestation. The etiology of the disease remains unclear and none of the advanced hypotheses (infectious, genetic, environmental) can by themselves explain its occurrence. There is a genetic susceptibility which is probably linked to many genes leading to a low related risk (less than two). A viral trigger mechanism in a person with a genetic predisposition is possible. New therapies result from a better understanding of the closed immune mechanisms of the disease.

[Delayed discovery of congenital diaphragmatic hernia: diagnostic difficulties. A report of two cases]. / Les hernies diaphragmatiques congénitales de révélation tardive: difficultés diagnostiques. A propos de deux cas.

Delayed revelation of congenital diaphragmatic hernias (CDH) is not uncommon and can represent 5-30% of total CDHs. Time before diagnosis may be prolonged, sometimes to the adult period. Respiratory and gastrointestinal symptoms are frequent but not specific. The clinical presentation of delayed CDH may thus mislead the practitioner. Diagnosis can be approached and/or confirmed by plain radiography. Outcome is usually favorable after surgery. We report two cases of delayed CDH and we discuss the difficulty of diagnosis.

[Temporal lobe epilepsy and ganglioglioma in children. Clinical aspects, imagery and neuropathology; nosological discussion of six cases]. / Epilepsie temporale et gangliogliome chez l'enfant. Aspects cliniques, imagerie et neuropathologie; discussion nosologique de six observations.

BACKGROUND: Gangliogliomas belong to debated nosological entity. They are classified as neuronal or neuroglial tumors. PATIENTS AND METHODS: Six children aged from 4 months to 15 years (mean age: 4 years and 6 months) were initially seen for partial seizures resistant to treatment. Tumoral resection was performed in all six. Diagnosis was made from immunohistological study of the tumor. DISCUSSION: Gangliogliomas are non-malignant, with a good prognosis, even if inaugural clinical manifestations are severe. Neuroradiological diagnosis with astrocytomas and cortical dysplasia is not easy, and pathological distinction from cortical dysplasia is difficult. CONCLUSION: The immunohistochemical confirmation of diagnosis permits a logical therapeutic attitude: complete resection of tumor is followed by an excellent outcome.

Factor V and VIII combined deficiency: clinical perioperative management for tonsillectomy in a child.

Combined factors V (FV) and VIII (FVIII) deficiency is a rarely seen hereditary coagulation disease. Experience of its management in surgery with a high-risk of bleeding is rare. The interest of this case report is to propose a strategy of perioperative management for such a deficit, but also to recall that a careful preoperative anesthetic evaluation with questioning and physical examination permits to detect unsuspected coagulation disorders and to schedule the preventive treatment. The protocol for the perioperative period consisted of the administration of desmopressin and fresh frozen plasma one hour before surgery. The administration of desmopressin was continued for 48hours. Fresh frozen plasma and tranexamic acid were administered during the first 9 postoperative days. A local bleeding occurred at 8 days (scab coming off) and required systematically a surgical hemostasis and an intensification of the therapeutic protocol. Recombinant plasmatic factor VIII was administered for 7 days together with a daily perfusion of fresh frozen plasma for a total treatment period of 14 days.
