[Management of the Sars-Cov2 pandemic in France - Benefit-risk balance at the collective versus individual level individual scale in children]. / Gestion de la pandémie à Sars-Cov2 en France ­ Balance bénéfice-risque à l'échelle collective versus à l'échelle individuelle chez les enfants.

According to the precautionary principle and facing the initial uncertainty of the potential seriousness of Covid-19, France has adopted collective measures understood as acceptable despite the deprivation of liberty and the known risks of long confinement on mental health. Such measures should be applied proportionately and cause the least possible harm. Among these, the closure of schools was decided by declination of those appearing in response plans to viral pandemics where children play a major role in the transmission of the disease (e.g. flu). In an unprecedented way, measures and constraints have been taken against the interests of children and to protect a vulnerable group other than the children themselves. From the perspective of children's health, the relationship between health gains from these measures and negative consequences has been unbalanced. The reduction in instruction time has reduced overall academic performance and has had adverse consequences for the socialization and development of children. Confinement has generated more serious domestic accidents, an increase in intra-family violence and marked collateral effects in terms of the mental health of adolescents. Very early on, the various Covid19-related publications showed that children were not the driving force behind this pandemic - If the initial application of collective measures was legitimate, the adaptation of measures at the individual level was out of step with the already known repercussions followed by those observed on the health of the child.

An unusual route of non-intentional intoxication by ecstasy in a toddler.

We report a pediatric case of ecstasy intoxication via an unusual route. A mother called the emergency services after her daughter had inserted an ecstasy pill into her nose. During transportation, the child developed hypertension, tachycardia, and tachypnea. She was admitted to the nearest regional hospital, where a physical examination revealed psychomotor agitation, mydriasis, hypertension, tachycardia, and no hyperthermia. Blood tests showed no abnormalities. She was subsequently transferred to a tertiary-level pediatric hospital. During transportation, she was described as being intensely agitated with persistent mydriasis, tachycardia, and high blood pressure. Urinary toxicological screening confirmed the presence of MDMA. She was discharged after 24 h.

Clinical decision-making training using the Script Concordance Test and simulation: A pilot study for pediatric residents.

BACKGROUND: Each year, new pediatric residents begin their shifts in the pediatric emergency room. While technical skills are often acquired during workshops, non-technical skills such as communication, professionalism, situational awareness, or decision-making are rarely tested. Simulation enables non-technical skills to be developed in situations frequently encountered in pediatric emergencies. Adopting an innovative approach, we combined two pedagogical methods: the Script Concordance Test (SCT) and simulation to improve clinical reasoning and non-technical skills of first-year pediatric residents in dealing with clinical situations involving febrile seizures. The aim of this work is to report the feasibility of such a combined training. METHODS: The first-year pediatric residents participated in a training session on how to manage a child attending the emergency department with a febrile seizure. At the beginning of the session, the trainees had to complete the SCT (seven clinical situations) and then participated in three simulation scenarios. Student satisfaction was assessed by means of a questionnaire at the end of the session. RESULTS: In this pilot study, 20 residents participated in the training. The SCT scores for the first-year pediatric residents were lower and more widely distributed than those of the experts with better concordance for diagnostic items compared to investigation or treatment items. All were satisfied with the teaching methods employed. Further sessions on additional topics relating to the management of pediatric emergency cases were requested. CONCLUSION: Although limited by the small size of our study, this combination of teaching methods was possible and seemed promising for the development of non-technical skills of pediatric residents. These methods are in line with the changes being made to the third cycle of medical studies in France and can be adapted to other situations and other specialties.

The psychological effects of COVID-19-related containment in children: The E-COCCON French study.

The first containment of the Sars-Cov2 pandemic had the potential to generate posttraumatic stress (PTS) symptoms in children. OBJECTIVE: The main objective of the study was to determine the prevalence of PTS symptoms within 6 weeks of the end of lockdown, in children contained between March 17, 2020 and May 11, 2020 in France. MATERIAL AND METHODS: This was a French prospective cross-sectional study between May 15 and July 2, 2020 conducted via telephone survey. Parents of children aged between 8 and 15 years were eligible. The invitation to participate was proposed through social networks (Instagram and Facebook), various local and national media, and by e-mail to the staff of our University Hospital Center. The PTS symptoms were assessed using the CRIES-13. A score of 30 and over has been confirmed as the cut-off for screening cases. RESULTS: During the study period, 379 children (male, n = 207) were included, their mean age was 10.8±2.1 years. Symptoms of PTSD were identified in 17% of the children (girls 20.5%, boys 13.5%). These children were younger (p = 0.04), lacked access to a private outdoor space (p < 0.0001; OR: 7.8), had parents whose profession exposed them more to the coronavirus, and had parents who were more afraid of COVID-19. CONCLUSION: After the first lockdown related to the pandemic crisis, children developed PTSD symptoms. The onset of such symptoms is correlated with gender, age, lockdown conditions, and parental perceptions. These last considerations were worse for pink- or blue-collar families, attesting to the subsequent intensification of health inequalities.

Description of a migrant pediatric population visiting the Toulouse Children's Hospital emergency department.

BACKGROUND: Today, one in eight migrants and one in two refugees are children. Since this population has been less studied than the adult population, there is little data available on the state of health of this pediatric migrant population and the reasons they seek care. OBJECTIVE: The objective of this study was to describe the sociodemographic and medical characteristics of a pediatric migrant population visiting an emergency department in order to better understand their specific needs. MATERIALS AND METHODS: This was a retrospective observational study using data from medical records and social surveys of migrant children who had visited the Toulouse pediatric emergency department between 1 January 2018 and 31 December 2018. RESULTS: A total of 203 migrant children, i.e., 344 emergency visits, were analyzed. The average age of the children was 3.3 years old. More than half (58.1%) of the children were from Eastern Europe; 71% visited due to infectious pathologies. The severity of the reasons for visiting (90% of the reasons for visiting had a CCMU (Clinical Classification of Emergency Patients) of 1 or 2) and the hospitalization rate (9%) were not higher in the pediatric migrant population than in the general pediatric population. We discovered associated diagnoses (e.g., scabies, anemia, oral and dental disorders) in connection with migration and/or the resulting vulnerability. There was a language barrier in 78% of the visits analyzed with underuse of professional interpreting (7%). CONCLUSION: Because of the journey they make, migrant children are likely to have specific health needs and require dedicated care.

Pediatric ocular trauma: Characteristics and outcomes among a French cohort (2007-2016).

Pediatric ocular trauma is a major cause of acquired monocular blindness. Post-traumatic visual impairment can lead to significant handicap. In France, recent data on the epidemiology of pediatric ocular trauma are lacking. AIM: To describe the characteristics of a pediatric cohort with ocular trauma and to analyse patient outcomes. MATERIAL AND METHODS: This was a retrospective observational study of pediatric ocular trauma (age<15 years) presenting to pediatric and ophthalmology emergency units of our tertiary university hospital between January 1, 2007 and December 31, 2016. Data were collected on: age, sex, time and circumstances of trauma, injury type and location, trauma mechanism, other associated injuries, hospitalisation rate and length of stay, treatment, and sequelae (visual impairment). Ocular traumas were classified according to the Birmingham Eye Trauma Terminology (BETT) system and the Ocular Trauma Score (OTS). RESULTS: A total of 337 children were included (247 males). The global mean age was 8.4±4.1 years (range 6 months to 14.9 years). The trauma occurred at home (51%) or in a public area (21%). Blunt objects (22%) and direct trauma (17%) were the main mechanisms. According to the BETT, 23% of ocular traumas were open-globe traumas (OGT): penetrating (n=39), perforating (n=12), with intraocular foreign body (n=24). Among closed-globe injuries (CGT), hyphema was the most frequent lesion (22%). Associated injuries were recorded in 32 patients. In all, 63% of patients had an OTS of 5 (good visual prognosis) while 39 children (12%) had an OTS of ≤3. In 47 patients, there was an initial surgery; 62% of children were hospitalised. By the end of the ophthalmic follow-up, 32 patients (9.5%) had sequelae. Children aged between 2 and 5 years had the greatest proportion of sequelae (15%). Compared with female patients, male patients were older (P=0.0007) and were more frequently injured by projectiles (P=0.036). Compared with CGT, OGT were more frequent among younger children (P=0.0015). Ocular injuries secondary to a projectile and spring-summer accidents were associated more frequently with a poor visual prognosis (OTS ≤3; P=0.036, OR=2.5 [1.1-5.8] and P<0.0001, OR=5.8 [3.2-10.7] respectively). COMMENTS: The annual admission for pediatric ocular trauma was stable during the study period (200 cases per 100,000 annual trauma admissions in the first period [2007-2011] and 195 cases per 100,000 during the most recent period [2012-2016]). Projectiles such as Airsoft gun bullets and paintball are still the cause of severe injuries while reports on ocular injuries secondary to blaster or Nerf guns use are starting to be published. CONCLUSION: The great majority of ocular traumas could be prevented, especially by wearing protective goggles during at-risk activities. French legislation should be stricter about the sale of any Airsoft gun to children under 18 years old. Parents must repeat educational warnings to their children handling sharp objects. The social and psychological burden of relative visual impairment is of importance: One in ten children will have a permanent visual defect.

Assessing the management of pediatric bone and joint infections according to French guidelines.

BACKGROUND: Short treatments for acute bone and joint infections (BJI) are recommended. We implemented a protocol in 2009 to improve diagnosis and bacteriological documentation, and to shorten antibiotic therapies as per French guidelines (French Pediatric Infectious Disease Group, GPIP). METHODS: To assess the impact of the new clinical protocol for BJI, we conducted a retrospective study from January 1st, 2006 to August 31st, 2012. Two successive cohorts were compared, before and after protocol implementation. All children suspected of community-acquired BJI were included. Confirmed osteomyelitis and septic arthritis required a positive bacterial isolate; otherwise, cases were considered probable. We compared clinical, biological, and radiological data; duration of antibiotic therapy and hospital length of stay; and complications and sequelae. RESULTS: A total of 377 children with suspected BJI were included. The bacteriological identification improved from 32% to 44% when patients were completely evaluated. Isolated bacteria were Staphylococcus aureus (53%), Kingella kingae (17%), Streptococcus pyogenes (15%), and Streptococcus pneumoniae (8%). Before protocol implementation, 70% of patients had a central venous line versus 9% after implementation. Mean duration of IV antibiotics (11 days versus 6 days), mean duration of total antibiotic therapy (45 days versus 32 days) and mean hospital length of stay (13 days versus 7 days) had significantly improved. CONCLUSION: Improvement in bacteriological diagnosis and shorter antibiotic regimens lead to shorter hospital length of stays with no additional morbidity. Simplifying the protocol and better diffusion among health professionals should contribute to shortening BJI treatment duration.

Purpura of the chin: Two consecutive cases.

Two healthy children, a 10-year-old boy and a 13-year-old girl, both with no previous medical history, unrelated, presented with pinpoint purpura of the chin and the upper lip. It had appeared 2 days before and extended from the chin to the lower lip. Neither had fever or recent trauma, nor had they taken any medication. Their vital parameters and physical examination were normal. Their peripheral blood cell counts and coagulation parameters were normal. A week later, upon the follow-up consultation, the purpuric lesions had disappeared and both children reported they had played the glass game.

Sudden death by arrythmia in a 4-year-old boy.

Cardiac arrhythmia with sudden death is rare in children but mainly due to ventricular tachycardia. In case of pulseless ventricular tachycardia, prehospital treatment is crucial with immediate cardiopulmonary resuscitation and external electrical cardioversion. We report the case of pulseless ventricular tachycardia in a child with no past medical history. Sinus rhythm was obtained after 12min of cardiorespiratory resuscitation and three external electrical shocks. An exhaustive diagnostic approach allow us to find its origin. The clinical progression was marked by a severe encephalopathy. The authors discuss different etiologies and treatment of arrhythmia in children, reviewing the pediatric algorithm for shockable rhythm.

[Severe hypercalcemia due to vitamin D intoxication]. / Hypercalcémie majeure secondaire à une intoxication par la vitamine D.

UNLABELLED: We report on a case of severe hypercalcemia due to vitamin D intoxication in a 4-month-old infant, CASE REPORT: A 4-month-old boy was admitted for anorexia, weakness, hypotonia, constipation and lethargy. Initial physical examination evidenced a severe axial hypotonia, signs of moderate intracellular dehydration, polyuria and leucocyturia. Hemodynamic parameters were normal. The infant's origin was Turkish. Basic blood chemistry showed a high serum calcium concentration of 4.28 and 4.55 mmol/l on a second control. The EKG showed a short QTc interval calculated at 0.34 s. Due to worsening neurological condition, the infant was referred to the pediatric intensive care unit. Because of the association of neurological impairment, EKG abnormality and high serum calcium level, haemodialysis was performed. Treatment included hyperhydration, high doses of intravenous of loop diuretics and sodium pamidronate infusion. Hormonal, radiological, abdominal and cardiac investigations combined with a new parental interview led to the diagnosis of vitamin D intoxication due to excessive daily administration. We were unable to determine the exact total amount because of the language barrier. Clinical outcome was marked by nephrocalcinosis without renal function impairment, iliac venous thrombosis secondary to the dialysis catheter and a full neurological recovery without sequelae after 3 months. DISCUSSION: Fear of rickets, especially in Turkish families residing in France, can lead some parents to administer massive daily quantities of vitamin D. This practice is facilitated by the possibility of purchasing high dosage forms of vitamin D via the Internet. When faced with an infant presenting with digestive disorders such as vomiting and constipation, associated with neurological troubles (lethargy, hypotonia) and hypercalcemia, vitamin D intoxication should be considered after tumoral, hormonal or malformative (Williams-Beuren syndrome) causes have been eliminated. Combined with hyperhydration and loop diuretics, biphosphonate infusion often allows to control hypercalcemia. Nephrocalcinosis seems correlated to chronic administration while cardiovascular disorders are more likely associated with massive acute vitamin D administration, severe dysrhythmia being rare in children in this context.

[When doors slam, fingers jam!]. / Quand les portes claquent, les doigts craquent!

AIM: Epidemiological analysis in a universitary paediatric emergency unit of children admitted after accidental injuries resulting from fingers crushed in a door. MATERIAL AND METHODS: Prospective, descriptive cohort study from September 6th, 2004 to July 1st, 2005 included all children admitted for finger injuries crushed in a non-automatic door. EXCLUSIONS: included accidents due to automatic doors, toy's or refrigerator doors, families who refused to participate to the study or families who had left the waiting area before medical examination. Collected data were patient and family characteristics, accident characteristics and its management. RESULTS: Three hundred and forty children affected by 427 digital lesions were included. The mean age was 5.5+/-3.8 years (range 4 months - 15.5 years). Male/female ratio was equal to 1.2: 1. Fifty-eight percent of patients belonged to families composed of 3 or more siblings. Ninety-three per cent of families came to hospital within the first 2 hours after the accident (mean delay 99+/-162 min, median range 54 minutes). Location of the accident was: domestic (62%, at home (64%)), at school (17%). Locations within the home were: the bedroom (33%), bathroom and toilets (21%). An adult was present in 75% of cases and responsible for the trauma in 25% of accidents, another child in 44%. The finger or fingers were trapped on the hinge side in 57% of patients. No specific safeguard devices were used by 94% of families. Among victims, 20% had several crushed digits; left and right hand were injured with an equal frequency. The commonest involved digits were: the middle finger (29%), the ring finger (23%). The nail plate was damaged in 60% of digital lesions, associated with a wound (50%), a distal phalanx fracture (P3) (12%). Six children had a partial or complete amputation of P3, 2 children a lesion of the extensor tendon, 1 child had a rupture of the external lateral ligament. Three percent of children required an admission to the paediatric orthopaedic surgery unit. Post-traumatic pain was mainly limited to the first 48 h (64%). Early complications included: 16 cases of infected injuries, 3 cases of pulpar necrosis. The total cost of hospital care was 71,500 euros, the average cost for hospitalised patient equal to 2100 euros and for ambulatory cases equal to 141 euros; the annual cost was estimated at 81,600 euros. CONCLUSION: Associated with potentially serious digital injuries, functional or inesthetic sequelae, this painful experience still remains too frequent in toddlers for a home accident that could be often prevented by the acquisition of specific protective doors devices and for a reasonable cost compared to the cost of hospital care.

[Hallucinations: Etiological analysis of children admitted to a pediatric emergency department]. / Hallucinations : analyse étiologique chez des enfants admis en service d'accueil des urgences.

Children's hallucinations pose the dual challenge of diagnosing a possible medical emergency and a possible psychiatric disorder. PURPOSE: The main objective was to analyze the causes of such hallucinations in children presenting to a pediatric emergency department. MATERIAL AND METHODS: We conducted a single-center, observational, retrospective study including all children aged less than 15 years experiencing hallucinations and admitted to our tertiary level pediatric emergency department between 1 January 2007 and 31 December 2015. The data collected were demographic; medical: previous medical or psychiatric history, current medications, associated clinical or psychiatric symptoms, type and character of hallucinations, length and recurrence of hallucinatory phenomena; and other biological, radiological and neurological explorations. RESULTS: Sixty-eight patients were included (29 boys). The mean age was 9.1±3 years (range, 2-14 years and 10 months; median, 9.2 years). Admissions were seasonal with a bimodal distribution (a peak during springtime and another one during fall). Hallucinations were mainly visual (90%), acute (77%) and complex (63%). Visual hallucinations were associated with other types of hallucinations: auditory (n=17), somatosensory (n=7). Fifteen children had a psychiatric history and had already experienced hallucinatory phenomena (93%). Among 47 patients (69%), these hallucinations were associated with other symptoms: agitation (41%), headaches (28%), hyperthermia (21%) and negative symptoms of the schizophrenia spectrum (15%). On admission, 20 patients (29%) had one or more treatments under way (34 drugs, 41% known for hallucinogenic adverse effects). Neurological explorations were undertaken in half of the cases. Toxicological analysis prescribed in 19 children was positive in five cases (26%). Fifty-three percent of patients were hospitalized and 51 children received a specialized follow-up (by a neurologist and/or a psychiatrist). A nonpsychiatric origin of these hallucinations was diagnosed in 29 patients (43%): neurological causes (n=10), infectious diseases (n=10), intoxications (n=5) and a medication side effect (n=4). CONCLUSION: Hallucinations with a suspected underlying psychiatric cause differed on several factors: chronic duration (p=0.02), an onset after 10 years of age (p=0.004), previous identical episodes (p=0.014) and a parental psychiatric history (p=0.036), auditory hallucinations (p=0.0009), absence of fever (p=0.005), headaches (p=0.036) and the presence of negative symptoms of the schizophrenic spectrum (p=0.02).

[Management of unintentional pediatric female genital trauma]. / Prise en charge des traumatismes du périnée accidentels chez la jeune fille.

INTRODUCTION: Unintentional pediatric female genital trauma is frequent in the daily practice of emergency wards. However, scientific data are rare in the literature, leading to variability in their management. The aim of this study was to evaluate our practice in order to obtain epidemiological data and define clinical guidelines. MATERIAL AND METHODS: We conducted a retrospective study from March 2013 to January 2015 and identified all emergency visits for this pathology. Data were extracted from the patients' charts and a statistical analysis was performed. RESULTS: One hundred and eighteen patients were admitted during the study period, with an average age of 5.9years. Straddle injuries accounted for 73 % of the injury mechanisms. Most wounds involved the majora and minora labia. Sixty-five patients did not require stitches (55.9 %); 29 patients were examined with Meopa® but 43 % required a more precise surgical exploration in the OR, due to the lack of compliance. Forty-six patients were sutured in the OR. Associated lesions (undiagnosed in the emergency department) were diagnosed during surgical exploration in 13 patients (22 %) with two urethral wounds. Significant wound size differences were observed in 69 % of patients between the pre- and intraoperative assessments. CONCLUSION: Surgical exploration under general anesthesia should be proposed for all unintentional female genital trauma unless the patient is older than 8 and allows complete examination at the emergency department consultation.

[B-natriuretic peptide and cardiological emergencies in childhood]. / Peptide natriurétique de type B et urgences cardiologiques chez l'enfant.

The increase in B-natiuretic peptide (BNP) is well correlated with cardiovascular symptoms in adults. Its use in children is recent and only partially evaluated. The authors undertook a prospective study of BNP concentrations and its kinetics in 54 children with an average age of 15 months (5 days to 11 years) admitted as paediatric emergencies. The symptoms were dyspnoea (60%), shock (15%), suspicion of Kawasaki disease (15%) and other (10%). Twenty children had BNP levels of more than 100 pg/ml related to decompensation of known congenital heart disease in 7 patients (average BNP 462 +/- 323 pg/ml), due to neonatal coarctation in 2 patients (BNP > 3000 pg/ml), due to cardiomyopathy in 6 patients (BNP= 2576 +/- 1215 pg/ml), due to an arrhythmia in 1 patient (BNP= 3754 pg/ml) and to Kawasaki disease in 4 patients (BNP= 521 +/- 448 pg/ml). Thirty-four children had BNP values of less than 100 pg/ml; 29 had no cardiac disease and 5 had known congenital heart disease with other symptoms. Measuring BNP is quick and economical and is a valuable aid in the diagnosis of cardiac dysfunction in symptomatic children in the emergency room. High BNP values seem to be correlated with the severity of the cardiac disease. Low BNP values seem to have a good negative predictive value in children without underlying cardiac disease. The interpretation of intermediary values, especially when there is previous cardiac disease, is more difficult in view of the absence of known threshold values for different haemodynamic situations. Further studies are required to determine the value of this test for the follow-up and setting up of prognostic values in children with congenital heart disease.

[Severe chloralose intoxication in a toddler]. / Intoxication sévère par le chloralose chez un nourrisson.

UNLABELLED: We report a case of an accidental intoxication in a 20-month-old boy resulting from the ingestion of a rodenticide containing alpha-chloralose. CASE REPORT: Three hours after initial admission to the pediatric emergency department for wheezing bronchitis, this patient was readmitted with a clinical presentation of respiratory insufficiency, a Glasgow coma score of 9 alternating with agitation, areflexia and unilateral mydriasis. Parental interview revealed he had episodes of shaking in the afternoon. Chest x-ray showed thoracic distension. Blood investigations, electrocardiogram, cardiac echography, brain CT scan and CSF were normal. Electroencephalography registered slow delta waves 2-3 cycles/min and an aspect of degraded waves and spikes. The patient was transferred to the intensive care unit where he fully recovered within 48 hours. A second parental interview and clinical presentation confirmed an intoxication with a rodenticide containing alpha-chloralose. The late clinical orientation did not allow us to perform a urinanalysis. DISCUSSION: Clinical association of coma, spontaneous or triggered myoclonias and bronchial hypersecretion are indicative of chloralose intoxication. Presence of specific abnormalities on electroencephalogram and a positive Fujiwara-Ross reaction in an urine sample are additional elements for the diagnosis. The prognosis is usually good after early management which combines gastric lavage, activated charcoal, sedation with benzodiazepines, tracheal intubation and artificial ventilation if required. Severe clinical cases described in voluntary intoxications in adults and teenagers occur very rarely in toddlers.

[Babywalker use (baby-trot, youpala): an unsafe practice]. / Utilisation du trotteur (baby-trot, youpala): une conduite à risque.

AIM: Epidemiological analysis of accidents related to babywalker use admitted to a pediatric emergency department. METHODS: Retrospective, descriptive study of injuries related to babywalkers admitted to the pediatric emergency department between January 1st, 2003 and December 31st, 2005. RESULTS: One hundred and seventy-eight children were admitted due to an accident related to babywalker use. The sex ratio was 1.7 with a male prevalence. Mean age was 11+/-4 months. Seventy-eight percent of babywalker-related injuries were attributable to fall down a flight of stairs. The mean number of steps that a child fell down was 7 (range 1-20 steps). The repartition of accidents was bimodal: during the year, 1 peak in May and 1 in October; during the week: 54% of the cases occurred on Thursday or on the weekend; during the day (1 peak between 10 a.m. and 1 p.m. and 1 peak between 4 p.m. and 7 p.m.). Non-severe head traumas represented the most frequent injury (72%). Twenty-one children were hospitalised for concussion (N=15), cranial fractures (N=3), forearm fracture (N=1), dental subluxation (N=1) and extradural hematoma (N=1). A social problem (families with unsafe domestic practices) was identified in 26 children (15%), 16 of these situations were recognized due to the retrospective character of the study and the analysis of hospital admissions after the first accident. CONCLUSION: Stairway related falls associated with babywalker use and fall down in the stairs are very frequent in children less than 1 year-old. This resulted in babywalkers being prohibited in Canada since 2004. In several countries, advocates are working to ban babywalkers. Active or passive prevention methods have shown their limits. This unsafe and dangerous practice should be banned in France.

[Necrotizing pneumonia and arthritis due to Staphylococcus aureus producing Panton and Valentine leukocidin in a 10-year-old boy]. / Pneumonie nécrosante et ostéoarthrite multifocale à Staphylococcus aureus producteur de la leucocidine de Panton et Valentine chez un garçon de 10 ans.

Staphylococcal necrotizing pneumonia producing the Panton Valentine leukotoxin (PVL) has been described for many years. The french reference center for staphylococcal toxaemia defined it with precision in 1999. A 10-year-old child, died in 36 hours from respiratory distress and shock. Staphylococcal pneumonia was suspected then confirmed: S. Aureus producing PVL was isolated in lung, blood and articulations.

Hyperglycemia is a risk factor for high-grade envenomations after European viper bites (Vipera spp.) in children.

CONTEXT: Hyperglycemia has been described in severe scorpion envenomation, we wanted to analyze if it was applicable to viper bites in children. AIM: To describe clinical, biological, and therapeutic characteristics of 83 children bitten by European viper (Vipera spp.) and to confirm that hyperglycemia is a risk factor for high-grade envenomation. MATERIAL AND METHODS: A retrospective study was conducted between 2001 and 2014 in the pediatric emergency department of a tertiary level children's hospital. Collected data were: age and sex of children; day and time of admission; day, time and circumstances of the accident; snake identification; bite location; envenomation severity; presence of fang marks; prehospital care; laboratory abnormalities, use of specific immunotherapy, associated treatments; length of stay; hospital course. RESULTS: Eighty-three children were included (62 boys, 21 girls). The mean age was 7.4 ± 3.9 years. Bites were most often located on the lower extremities (66%). The classification of envenomation was: 83% low grade (absent or minor envenomation) and 17% high grade (moderate to severe envenomation). All high-grade envenomations received specific immunotherapy (Viperfav(TM), (Aventis Pasteur, MSD, Lyon, France). Being bitten on an upper extremity (odds ratio [OR] 51.1 95% class interval [CI] [6.1-424], p < 0.0001), during the afternoon (OR 13.4 95% CI [1.7-107.9], p = 0.015), feeling violent pain (OR 4.2 95% CI [1.1-16.5], p = 0.023), and high initial plasma glucose level (6.5 ± 1.7 mmol/L versus 5.0 ± 0.9 mmol/L, p = 0.027) were associated with a significant risk of high-grade envenomation. CONCLUSION: We have confirmed a potential link between initial hyperglycemia and the risk of progression to high-grade envenomation as well as its association with other published predictive factors.
