RESUMEN
Background: Staphylococcus aureus is a well-known bacterium associated with carriage and responsible for different types of infections. The Panton-Valentine leucocidin (PVL) is a key virulence factor causing tissue necrosis. PVL can, however, be present in both benign and life-threatening infections. Case reports and management: We present three pediatric severe infections occurring over a period of only three weeks, in February 2021, and caused by genetically unrelated methicillin-sensitive Staphylococcus aureus producing PVL in a tertiary children's hospital in Belgium. The first one presented with necrotizing pneumonia, the second one with a neck abscess extended to the mediastinum, and the last one had sacral osteomyelitis complicated by endocarditis. The management of these infections is mostly based on expert opinions. The most appropriate treatment seems to be the combination of early surgical drainage of infected collections with an antibiotic regimen associating two antibiotics; beta-lactams and either clindamycin or linezolid. Human immunoglobulins also appear to be useful as adjunctive therapy. Conclusion: PVL-producing Staphylococcus aureus is associated with life-threatening infections in children. Prompt management is needed including surgery and appropriate antibiotic regimens.
RESUMEN
BACKGROUND: Creatinine is distributed between the intracellular and extracellular compartments, and as a result, the measurement of its concentration is strongly related to the fluid status of the patient. An interest has been shown in correcting measured serum creatinine levels according to the fluid balance in order to better specify the degree of acute kidney injury (AKI). METHODS: We conducted a retrospective observational study of 33 children, aged 0 to 5 years, admitted to the pediatric intensive care unit for acute respiratory distress syndrome treated by extracorporeal membrane oxygenation. We compared measured and corrected creatinine and assessed the degree of agreement between these values using both Cohen's kappa and Krippendorff's alpha coefficient. RESULTS: In our cohort, 37% of the classifications made according to measured creatinine levels were erroneous and, in the majority of cases, the degree of AKI was underestimated. CONCLUSION: Correction of the measured creatinine value according to the degree of fluid overload may result in more accurate diagnosis of AKI.

PURPOSE: Viral bronchiolitis is a major cause of pediatric intensive care unit (PICU) admission. Insight in the trends of bronchiolitis-associated PICU admissions is limited, but imperative for future PICU resource and capacity planning. MATERIALS AND METHODS: We retrospectively studied trends in PICU admissions for bronchiolitis in six European sites, including three full national registries, between 2000 and 2019 and calculated population-based estimates per 100,000 children where appropriate. Information concerning risk factors for severe disease and use of invasive mechanical ventilation was also collected when available. RESULTS: In total, there were 15,606 PICU admissions for bronchiolitis. We observed an increase in the annual number, rate and estimates per 100,000 children of PICU admissions for bronchiolitis at all sites over the last two decades, while the proportion of patients at high risk for severe disease remained relatively stable. CONCLUSIONS: The international increased burden of bronchiolitis for the PICU is concerning, and warrants further international attention and investigation.

BACKGROUND: Acute bronchiolitis is the most frequent cause of respiratory distress in pediatric emergency medicine. The risk of respiratory failure is frequently over evaluated, and results in systematic vascular access. METHODS: We conducted a prospective observational study in children under 18 months of age hospitalized for bronchiolitis. The aim of the study was to evaluate whether catheter insertion was useful for management. We monitored the number of catheters inserted in the emergency department and their subsequent use for rapid sequence intubation, adrenaline administration, or antimicrobial therapy. We recorded the number of secondary pediatric intensive care unit (ICU) admissions. RESULTS: We followed 162 patients and compared two populations, children with (population A, n = 35) and without (population B, n = 127) catheter insertion. There were no significant differences in age, oxygen saturation, heart rate, c-reactive protein, neutrophil count and the number of times nebulization was conducted at admission. Population A compared to B had a significantly higher temperature (38.1 ± 0.9 vs. 37.6 ± 0.7°C, P = 0.004) and respiratory rate (64 ±13 vs. 59 ±17, P = 0.033). Twelve patients were secondarily transferred to pediatric ICU, 3 from population A and 9 from B (NS). In a multivariate analysis, no significant relationship was found between ICU admission, venous access placement and potential confounding factors (pneumonia, age < 6 months, age < 3 months, food intake < 60%, temperature > 38° C, heart rate > 180 bpm, respiratory rate > 60/min, SpO2 < 95%, Spo2 < 90%, oxygen therapy, positive respiratory syncytial virus [RSV] sampling). Except for antimicrobial therapy (n = 32), catheters inserted in the emergency department were used in 5 patients for intravenous rehydration and in one patient in pediatric ICU for rapid sequence intubation. CONCLUSIONS: There were no life-threatening events that required immediate venous access for cardiopulmonary resuscitation. Medical treatment could be administered orally or via nasogastric tube in most cases. Peripheral catheterization was useless in immediate emergency management and only one child required a differed rapid sequence intubation.

This section provides guidelines on the management of critically ill or injured infants, children and adolescents before, during and after respiratory/cardiac arrest.
RESUMEN
The high mortality of pediatric acute respiratory distress syndrome (PARDS) is partly related to fluid overload. Extracorporeal membrane oxygenation (ECMO) is used to treat pediatric patients with severe PARDS, but can result in acute kidney injury (AKI) and worsening fluid overload. The objective of this study was to determine whether the addition of CRRT to ECMO in patients with PARDS is associated with increased mortality. METHODS: We conducted a retrospective 7-year study of patients with PARDS requiring ECMO and divided them into those requiring CRRT and those not requiring CRRT. We calculated severity of illness scores, the amount of blood products administered to both groups, and determined the impact of CRRT on mortality and morbidity. RESULTS: We found no significant difference in severity of illness scores except the vasoactive inotropic score (VIS, 45 ± 71 vs. 139 ± 251, p = 0.042), which was significantly elevated during the initiation and the first three days of ECMO. CRRT was associated with an increase in the use of blood products and noradrenaline (p < 0.01) without changing ECMO duration, length of PICU stay or mortality. CONCLUSION: The addition of CRRT to ECMO is associated with a greater consumption of blood products but no increase in mortality.

A 4-month-old patient was admitted to the emergency room for vomiting, weight gain, food refusal and hypertension. Blood gases showed a metabolic acidosis with increased anion gap. Laboratory finding revealed severe renal failure (creatinine 8 mg/dL). Renal ultrasound showed an important hyperechogenicity of the parenchyma with loss of cortico-medullar differentiation suggesting a nephronophytosis. Genetic testing was negative. Urine oxalate levels were increased to 140 µmol/L. New genetic tests were positive for type I hyperoxaluria. The authors discuss the management of hyperoxaluria.

Neuromyelitis optica spectrum disorder is a rare, relapsing autoimmune disease of the central nervous system. Various initial presentations can delay diagnosis and treatment. A 14-year-old girl was admitted to the emergency department owing to respiratory insufficiency. Repeated history-taking and neuroimaging revealed an area postrema syndrome. A diagnosis of neuromyelitis optica spectrum disorder with positive aquaporin-4 antibodies has finally been established. The patient improved significantly with immunosuppressive therapy. However, her 3-year follow-up still showed sleep-disordered breathing requiring nocturnal bilevel positive airway pressure therapy. We report an original case of NMOSD leading to persistent central sleep apnea syndrome.

A retrospective observational study has been set up in order to compare feeding tolerance and energy delivery in children fed with a semi-elemental diet or a polymeric diet after congenital heart surgery. The study took place in the intensive care unit of a tertiary children's hospital. One hundred children were included: 56 received a semi-elemental diet and 44 received a polymeric diet. Patients were aged between 2 days and 6 years. Data from patients were obtained from medical files between February 2014 and May 2016. The feeding protocol was changed in March 2015 when a semi-elemental diet was substituted for the polymeric diet. Primary outcome was the feeding tolerance. Feeding intolerance occurs if the patient has more than two episodes of emesis or more than four liquid stools per day. Feeding tolerance in the semi-elemental and polymeric diet groups was comparable: emesis occurred in 14.3% versus 6.8% of patients, respectively (p = 0.338); diarrhea occurred in 3.6% versus 4.5% (p = 1000); post-pyloric feeding was necessary in 14% versus 9% (p = 0.542). Energy delivery was also comparable in the two groups: on postoperative day 2, the semi-elemental diet group reached 50% of the caloric target versus 52% in the polymeric diet group (p = 0.283); on day 5, 76% versus 85% (p = 0.429); and on day 10, 105% versus 125% (p = 0.397). Energy delivery was insufficient on postoperative days 2 and 5, but nutritional goals were achieved by day 10. No patient developed necrotizing enterocolitis in our population.Conclusion: the present study suggests that the feeding tolerance to a semi-elemental or a polymeric diet is similar after CHS.What is Known:â¢Nutrition can modify prognosis in PICUâ¢Different types of diet have been tested in children with intestinal disorders or with congenital heart disease. None of these diets have shown to be superior in terms of feeding tolerance.What is New:â¢Semi elemental and polymeric diets seem to have the same feeding tolerance in PICU after cardiac surgery for congenital heart disease.

The authors describe two cases of metabolic acidosis, caused by diabetic ketoacidosis in the first case and by dehydration following gastroenteritis in the second one. Both patients were followed with noninvasive end-tidal CO2 (ETCO2) monitoring. A correlation between EtCO2 and PCO2 and HCO3- has been established in the literature. Noninvasive ETCO2 is used in only 5-6% of metabolic emergencies. In contrast, users described its use as easy and convenient.
RESUMEN
Severe accidental hypothermia has been demonstrated to affect ventricular systolic and diastolic functions, and rewarming might be responsible of cardiovascular collapse. Until now, there have been only a few reports on severe accidental hypothermia, none of which involved children. Herein, we describe here a rare case of heart failure in a 6-year-old boy admitted to the emergency unit owing to severe hypothermia and malnutrition. After he was warmed up (core temperature of 27.2°C at admission), he developed cardiac arrest, requiring vasoactive amines administration, and veno-arterial extracorporeal membrane oxygenation. Malnutrition and refeeding syndrome might have caused the thiamine deficiency, commonly known as beriberi, which contributed to heart failure as well. He showed remarkable improvement in heart failure symptoms after thiamine supplementation. High-dose supplementation per os (500 mg/day) after reconstitution of an adequate electrolyte balance enabled the patient to recover completely within 2 weeks, even if a mild diastolic cardiac dysfunction persisted longer. In conclusion, we describe an original pediatric case of heart failure due to overlap of severe accidental hypothermia with rewarming, malnutrition, and refeeding syndrome with thiamine deficiency, which are rare independent causes of cardiac dysfunction. The possibility of beriberi as a cause of heart failure and adequate thiamine supplementation should be considered in all high-risk patients, especially those with malnutrition. Refeeding syndrome requires careful management, including gradual electrolyte imbalance correction and administration of a thiamine loading dose to prevent or correct refeeding-induced thiamine deficiency.
RESUMEN
BACKGROUND: In order to decrease the incidence of ventilator-associated pneumonia (VAP) in Belgium, a national campaign for implementing a VAP bundle involving assessment of sedation, cuff pressure control, oral care with chlorhexidine and semirecumbent position, was launched in 2011-2012. This report will document the impact of this campaign. METHODS: On 1 day, once a year from 2010 till 2016, except in 2012, Belgian ICUs were questioned about their ventilated patients. For each of these, data about the application of the bundle and the possible treatment for VAP were recorded. RESULTS: Between 36.6 and 54.8% of the 120 Belgian ICUs participated in the successive surveys. While the characteristics of ventilated patients remained similar throughout the years, the percentage of ventilated patients and especially the duration of ventilation significantly decreased before and after the national VAP bundle campaign. Ventilator care also profoundly changed: Controlling cuff pressure, head positioning above 30° were obtained in more than 90% of cases. Oral care was more frequently performed within a day, using more concentrated solutions of chlorhexidine. Subglottic suctioning also was used but in only 24.7% of the cases in the last years. Regarding the prevalence of VAP, it significantly decreased from 28% of ventilated patients in 2010 to 10.1% in 2016 (p ≤ 0.0001). CONCLUSION: Although a causal relationship cannot be inferred from these data, the successive surveys revealed a potential impact of the VAP bundle campaign on both the respiratory care of ventilated patients and the prevalence of VAP in Belgian ICUs encouraging them to follow the guidelines.
RESUMEN
BACKGROUND: Repair of congenital heart defects involving the right ventricular outflow tract may require the implantation of a right ventricle to pulmonary artery conduit. This conduit is likely to be replaced during childhood. This study compares the operative outcomes of the replacement procedure of Contegra® and homografts in pulmonary position. METHODS: From 1999 to 2016, 82 children underwent 87 right ventricle to pulmonary artery conduit replacements (60 Contegra® and 27 homografts). Demographics, operative and clinical data were obtained through a retrospective review of the medical records. The two groups were matched for comparison using propensity score matching. All the procedures were performed by the same team of surgeons. RESULTS: No statistically significant difference was observed between the two groups when considering the operative data for anesthesia, surgery, cardiopulmonary bypass and aortic clamping durations. A peroperative complication rate of 13.47% and 15.36% in Contegra® and homograft replacement groups respectively (p value = 0.758) was observed. There was no difference regarding the blood loss and fluid input. No statistically significant difference was observed between the two groups for the post-operative morbidity. We considered the Pediatric Risk of Mortality (PRISM) score, the day of extubation, the day of withdrawal of inotropic drugs, the length of the intensive care unit stay and the length of hospital stay. The overall mortality is 2.3% but there is no statistically significant difference between the two groups. CONCLUSION: Right ventricle to pulmonary artery conduit replacement procedure can be achieved with a low surgical morbidity or mortality, not influenced by the type of conduit that is replaced. Therefore, the choice between homograft or Contegra® for right ventricle to pulmonary artery reconstruction should not be influenced by the future surgical risk during the replacement procedure. TRIAL REGISTRATION: NCT03048071 . Registered 9 February 2017 (retrospectively registered).

OBJECTIVES: This summary of the European guidelines for pediatric cardiopulmonary resuscitation (CPR) emphasizes the main changes and encourages health care professionals to keep their pediatric CPR knowledge and skills up to date. Basic and advanced pediatric CPR follow the same algorithm in the 2015 guidelines. The main changes affect the prevention of cardiac arrest and the use of fluids. Fluid expansion should not be used routinely in children with fever in the abuse of signs of shock because too high a volume can worsen prognosis. Rescue breaths should last around 1 second in basic CPR, making pediatric recommendations consistent with those for adults. Chest compressions should be at least as deep as one-third the anteroposterior diameter of the thorax. Most children in cardiac arrest lack a shockable rhythm, and in such cases a coordinated sequence of breaths, chest compressions, and administration of adrenalin is essential. An intraosseous canula may be the first choice for introducing fluids and medications, especially in young infants. In treating supraventricular tachycardia with cardioversion, an initial dose of 1 J/kg is currently recommended (vs the dose of 0.5 J/kg previously recommended). After spontaneous circulation is recovered, measures to control fever should be taken. The goal is to reach a normal temperature even before arrival to the hospital.
OBJETIVO: Este artículo resume las recomendaciones europeas de reanimación cardiopulmonar (RCP) pediátricas, destacando los principales cambios e intenta animar a los profesionales a actualizar y mantener sus conocimientos y habilidades en RCP pediátrica. Las recomendaciones europeas del año 2015 mantienen el mismo algoritmo de actuación en la RCP básica y avanzada pediátrica. Los cambios más significativos son: en la prevención de la parada cardiaca (PC), los niños con enfermedad febril sin signos de shock no deben recibir de forma rutinaria expansiones de fluidos porque un volumen excesivo puede empeorar el pronóstico. En la RCP básica se recomienda que la administración de la respiración dure alrededor de 1 segundo, para unificar las recomendaciones con las del adulto. En las compresiones torácicas el esternón debe deprimirse por lo menos un tercio del diámetro torácico anteroposterior. En el niño, la mayoría de las PC tienen ritmos no desfibrilables y en ellos la secuencia coordinada de ventilación y compresiones torácicas y administración de adrenalina es el tratamiento esencial. La vía intraósea, sobre todo en los lactantes, puede ser el acceso vascular de primera elección. En el tratamiento de la taquicardia supraventricular, cuando se realice cardioversión como tratamiento, se recomienda utilizar una dosis inicial de 1 J/kg (antes se recomendaba 0,5 J/kg). En los cuidados postresucitación tras la recuperación de la circulación espontánea, se deben tomar medidas para evitar la fiebre, teniendo como objetivo conseguir la normotermia ya desde el ámbito extrahospitalario.
