Complicated Falciparum Malarial ARDS Requiring Noninvasive Support.

Severe plasmodium falciparum infection can induce respiratory distress and clinical ARDS in children, requiring intensive care admission and respiratory support. We present 3 cases of imported malarial acute respiratory distress syndrome requiring noninvasive ventilation in the pediatric intensive care unit, in the absence of any cerebral involvement. Radiological features and their relationship with severe hematological complications are also illustrated.

Intranasal human-recombinant NGF administration improves outcome in children with post-traumatic unresponsive wakefulness syndrome.

BACKGROUND: Severe traumatic brain injury (TBI) is one of the most dramatic events in pediatric age and, despite advanced neuro-intensive care, the survival rate of these patients remains low. Children suffering from severe TBI show long-term sequelae, more pronounced in behavioral, neurological and neuropsychological functions leading to, in the most severe cases, an unresponsive wakefulness syndrome (UWS). Currently, no effective treatments can restore neuronal loss or produce significant improvement in these patients. In experimental animal models, human- recombinant Nerve Growth Factor (hr-NGF) promotes neural recovery supporting neuronal growth, differentiation and survival of brain cells and up-regulating the neurogenesis-associated processes. Only a few studies reported the efficacy of intranasal hr-NGF administration in children with post- traumatic UWS. METHODS: Children with the diagnosis of post-traumatic UWS were enrolled. These patients underwent a treatment with intranasal hr-NGF administration, at a total dose of 50 gamma/kg, three times a day for 7 consecutive days. The treatment schedule was performed for 4 cycles, at one month distance each. Neuroradiogical evaluation by Positron Emission Tomography scan (PET), Single Photon Emission Computed Tomography (SPECT), Electroencephalography (EEG), and Power Spectral Density (PSD) was determined before the treatment and one month after the end. Neurological assessment was also deepened by using modified Ashworth Scale, Gross Motor Function Measure, and Disability Rating Scale. RESULTS: Three children with post-traumatic UWS were treated. hr-NGF administration improved functional (PET and SPECT) and electrophysiological (EEG and PSD) assessment. Also clinical conditions improved, mainly for the reduction of spasticity and with the acquisition of voluntary movements, facial mimicry, attention and verbal comprehension, ability to cry, cough reflex, oral motility, and feeding capacity, with a significant improvement of their neurological scores. No side effects were reported. CONCLUSION: These promising results and the ease of administration of this treatment make it worthwhile to be investigated further, mainly in the early stages from severe TBI and in patients with better baseline neurological conditions, to explore more thoroughly the benefits of this new approach on neuronal function recovery after traumatic brain damage.

Multisystemic involvement of post-traumatic fat embolism at a Pediatric Trauma Center: a clinical series and literature review.

Post-traumatic fat embolism syndrome (FES) is a severe complication consequent to bone fractures. The authors describe its clinical features and management in a population of teenagers by detailing demographics, organ involvement, laboratory, and imaging findings, as well as outcome. Moreover, a systematic review of pediatric published case reports of post-traumatic FES is provided. First, a series of eight episodes of post-traumatic FES that occurred in seven patients (median age 16.0 years, IQR 16.0-17.5) admitted to a pediatric intensive care unit (PICU) in an 8-year period was analyzed through a retrospective chart review. Secondly, a systematic research was performed on PUBMED database. Trauma patients ≤ 18 years without comorbidities in a 20-year period (2002-2022) were included in the review. Neurological impairment was present in five out of seven patients, and a patent foramen ovale was found in four cases. Hemodynamic instability requiring vasoactive drugs was recorded in four patients. A severe form of acute respiratory distress syndrome (ARDS) occurred in five cases, with the evidence of hemorrhagic alveolitis in three of them. In the literature review, eighteen cases were examined. Most cases refer to adolescents (median age 17.0 years). More than half of patients experienced two or more long bone fractures (median: 2 fractures). Both respiratory and neurological impairment were common (77.8% and 83.3%, respectively). 88.9% of patients underwent invasive mechanical ventilation and 33.3% of them required vasoactive drugs support. Neurological sequelae were reported in 22.2% of patients. CONCLUSION: Post-traumatic FES is an uncommon multi-faceted condition even in pediatric trauma patients, requiring a high level of suspicion. Prognosis of patients who receive prompt support in an intensive care setting is generally favorable. WHAT IS KNOWN: •Post-traumatic fat embolism syndrome is a severe condition complicating long bone or pelvic fractures. •Little is known about clinical features and management in pediatric age. WHAT IS NEW: •Post-traumatic fat embolism syndrome can cause multiple organ failure, often requiring an intensive care management. •Prompt supportive care contributes to a favorable prognosis.

Needleless inhaled anesthesia with sevoflurane: Advantages of a simplified approach for children with spinal muscular atrophy undergoing intrathecal administration of nusinersen.

BACKGROUND: Intrathecal nusinersen administration, a fundamental step in the treatment of spinal muscular atrophy, is challenging in children. AIMS: This retrospective monocentric analysis of prospectively collected data evaluated the feasibility of needleless general anesthesia exclusively with sevoflurane, without imaging guidance, for children undergoing nusinersen administration in a 24-month period. METHODS: Clinical data included demographics, type of spinal muscular atrophy, presence and severity of scoliosis. Primary outcome was defined by the number of predefined sentinel adverse events related to anesthesia. Secondary outcomes were assessed by duration of the procedure, number of lumbar puncture attempts, and number of failures. Other measures included number and type of moderate, minor and minimal adverse events, as well as number and type of puncture-related adverse events. RESULTS: 116 patients (mean age: 8.7 (SD 6.9) years; with scoliosis: 49.1%) underwent 250 lumbar punctures; two cases of prolonged desaturation, considered as sentinel adverse events, (0.8%) were recorded during anesthesia (primary outcome). None of the patients underwent orotracheal intubation nor required an unplanned admission in the Pediatric Intensive Care Unit. No patient required an unplanned or prolonged hospitalization after the procedure. Mean number of puncture attempts was 1.6 (SD 1.3), and mean duration of the procedure was 14.1 (SD 8.3) minutes. No failure in the drug administration occurred (secondary outcomes). CONCLUSION: In this single-center experience, needleless general anesthesia with inhaled sevoflurane without imaging guidance has been shown to be feasible for children with spinal muscular atrophy undergoing lumbar puncture for nusinersen administration.

Delayed tension hemothorax after chest trauma in children.

Blunt chest injury is commonly observed in the Pediatric Emergency Department and Intensive Care Unit since up to 30% of children with traumatic injury sustain injury to the thorax. Differently from adults, who present with concomitant rib or sternoclavicular fractures in 70% of cases, more than half of childhood chest injuries occur without any bone fracture, mostly causing lung contusions. This lower rate of rib fractures and near absence of flail chest in children may be due to greater elasticity of the pediatric cartilaginous and bony skeleton. Whenever a rib fracture is present, underlying complications should be evaluated carefully (i.e., air leaks or blood effusions). Depending on the trauma mechanism, even minor injuries should raise the suspicion of pathologic bone fractures.

Brugada pattern revealed during SARS-COV-2-related multi-systemic inflammatory syndrome in a 6-year-old child.

Rhythm abnormalities are rare during COVID-19-related multisystem inflammatory syndrome in children (MIS-C). We are reporting the detection of type I Brugada pattern in a 6-year-old child with MIS-C. Following the start of treatment (systemic steroids and immunoglobulins), a gradual evolution of cardiac rhythm up to normalisation was observed, concomitantly with a progressive reduction of inflammatory markers.

Noninvasive Ventilation in a Pediatric Trauma Center: A Cohort Study.

OBJECTIVE: To determine whether non-invasive ventilation (NIV) can avoid the need for tracheal intubation and/or reduce the duration of invasive ventilation (IMV) in previously intubated patients admitted to the pediatric intensive care unit (PICU) and developing acute hypoxemic respiratory failure (AHRF) after major traumatic injury. STUDY DESIGN: A single center observational cohort study. SETTING: Pediatric ICU in a University Hospital (tertiary referral Pediatric Trauma Centre). POPULATION: During the 48-month study period, 276 patients (median age 6.4 years) with trauma were admitted to PICU; among 86 of them, who suffered from AHRF and received ventilation (IMV and/or NIV) for more than 12 hrs, 32 patients (median age 8.5 years) were treated with NIV. INCLUSION/EXCLUSION CRITERIA: Inclusion criteria: at least 12 hours of NIV; exclusion criteria: patients with facial trauma or congenital malformations; patients receiving IMV <12 hours or perioperative ventilation. MEASUREMENTS AND RESULTS: Among NIV patients, 27 (84,3%) were previously on IMV, while 5 (15,6%) could be managed exclusively with NIV. In patients with post-extubation respiratory distress, NIV was successful in 88.4% of cases. Before starting NIV, P/F ratio was 242.7 ± 71. After 8 hours of NIV treatment, a significant oxygenation improvement (PaO2/FiO2 = 354.3 ± 81; p = 0.0002) was found, with no significant changes in carbon dioxide levels. A trend toward increasing ventilation-free time has been evidenced; NIV resulted feasible and generally well tolerated. CONCLUSIONS: AHRF in trauma patients is multifactorial and may be due to many reasons, such as lung contusion, aspiration of blood or gastric contents. Systemic inflammatory response and transfusions may also contribute to hypoxia. Our pilot study strongly suggests that NIV can be applied in post-traumatic AHRF: it may successfully reduce the time of both invasive ventilation and deep sedation. Further data from controlled studies are needed to assess the advantage of NIV in pediatric trauma.

Neuromuscular Blocker Use in Critically Ill Children: Assessing Mortality Risk by Propensity Score-Weighted Analysis.

OBJECTIVES: We aim to describe the use of continuous infusion of neuromuscular blocking agents in mechanically ventilated critically ill children and to test its association with in-hospital mortality. DESIGN: Multicenter, registry-based, observational, two-cohort-comparison retrospective study using prospectively collected data from a web-based national registry. SETTING: Seventeen PICUs in Italy. PATIENTS: We included children less than 18 years who received mechanical ventilation and a neuromuscular blocking agent infusion from January 2010 to October 2017. A propensity score-weighted Cox regression analysis was used to assess the relationship between the use of neuromuscular blocking agents and in-hospital mortality. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 23,227 patients admitted to the PICUs during the study period, 3,823 patients were included. Patients who received a continuous infusion of neuromuscular blocking agent were more likely to be younger (p < 0.001), ex-premature (p < 0.001), and presenting with less chronic respiratory insufficiency requiring home mechanical ventilation (p < 0.001). Reasons for mechanical ventilation significantly differed between patients who received a continuous infusion of neuromuscular blocking agent and patients who did not receive a continuous infusion of neuromuscular blocking agent, with a higher frequency of respiratory and cardiac diagnosis among patients who received neuromuscular blocking agents compared with other diagnoses (all p < 0.001). The covariates were well balanced in the propensity-weighted cohort. The mortality rate significantly differed among the two cohorts (patients who received a continuous infusion of neuromuscular blocking agent 21% vs patients who did not receive a continuous infusion of neuromuscular blocking agent 11%; p < 0.001 by weighted logistic regression). Patients who received a continuous infusion of neuromuscular blocking agent experienced longer mechanical ventilation and PICU stay (both p < 0.001 by weighted logistic regression). A weighted Cox regression analysis found the use of neuromuscular blocking agents to be a significant predictor of in-hospital mortality both in the unadjusted analysis (hazard ratio, 1.7; 95% CI, 1.3-2.2) and in the adjusted one (hazard ratio, 1.6; 95% CI, 1.2-2.1). CONCLUSIONS: Thirteen percent of mechanically ventilated children in PICUs received neuromuscular blocking agents. When adjusting for selection bias with a propensity score approach, the use of neuromuscular blocking agent was found to be a significant predictor of in-hospital mortality.

Neonatal Life-Threatening Nonoliguric Hyperkalemia Under Therapeutic Hypothermia.

To illustrate our experience with two cases of neonatal life-threatening hyperkalemia during therapeutic hypothermia (TH) despite a normal acid-base status, urine output, and preserved renal function. Clinical cases are presented from Pediatric Intensive Care Unit (PICU) admission to the onset of the hyperkalemia, with related complications and after resolution. Similar cases were not retrieved from a critical review of pertinent literature. Severe hyperkalemia pathophysiology and risk factors have been debated. Two full-term adequate for weight female neonates were admitted to PICU because of perinatal asphyxia who underwent TH. Prenatal history was completely uneventful, nor hereditary genetic conditions were reported; moreover, long-term follow-up ruled out any metabolic or renal disease. Despite an accurate evaluation of previous clinical series and literature on TH and perinatal asphyxia, these hyperkalemic episodes remain unexplained. The hypoxic-ischemic insult may affect multiple organs, mainly central nervous system, heart, lung, and kidneys; acute muscle breakdown and consequent rising of myoglobin may also have a precipitating role in acute kidney failure (AKF) and hyperkalemia. Electrolyte imbalance is a possible finding as a consequence of combined cell injury and AKF. In contrast, an isolated severe hyperkalemia is exceedingly rare in nonoliguric neonates.

Influence of summer tourist flows on occurrence of out-of-hospital cardiac arrest in an Italian tourist-intensive area.

INTRODUCTION: The study aims to evaluate the seasonal variation of out-of hospital cardiac arrest (OHCA) in a tourist-intensive area. METHODS: Data of all OHCA treated by the Emergency Medical Service of Lecce (LE-EMS), Italy, between 2013 and 2017, were retrospectively analyzed and complemented with information about tourist flows, in order to determine the influence of the seasonal variation of population on incidence and outcome. RESULTS: Tourist arrivals were around 1,700,000 per year, mostly in summer, adding up to 803,161 residents. The occurrence of OHCA did not show a monthly variation when referring to the resident population (p = 0.90). When taking into account the tourist flows, a difference in occurrence of OHCA across months was found, with the highest rate of arrests in December and the lowest in August (10.3 vs 3.4 per 100,000 persons, p < 0.01). No difference was found in terms of EMS arrival time and event survival rate between summer and the rest of the year (13.6 vs 13.8 min, p = 0.55, and 4.4% vs 4.5%, p = 0.86, respectively). CONCLUSION: In summer tourism areas, the occurrence of OHCA is unchanged throughout the year, while the actual population presents seasonal increases. Summer enhancement of provincial EMS may contribute to maintain the performance of emergency care.

Miliary tuberculosis leading to acute respiratory distress syndrome: Clinical experience in pediatric intensive care.

Acute respiratory distress syndrome (ARDS) represents a rare complication of miliary tuberculosis (TB) in the adult setting, and it is even less common in the pediatric population. The presence of comorbidities and the possibility of a delayed diagnosis may further impair the clinical prognosis of critically ill patients with disseminated TB and acute respiratory failure. In this report, we present a case series of five pediatric patients with miliary TB and ARDS, where rescue and multimodal respiratory support strategies have been applied with a favorable outcome in more than half of them. The burden of miliary TB over time on a general pediatric intensive care unit-including two ARDS patients-is also illustrated.

Weaning of Children With Burn Injury by Noninvasive Ventilation: A Clinical Experience.

The aim of this study was to report the respiratory management of a cohort of infants admitted to a Pediatric Intensive Care Unit (PICU) over a 7-year period due to severe burn injury and the potential benefits of noninvasive ventilation (NIV). A retrospective review of all pediatric patients admitted to PICU between 2009 and 2016 was conducted. From 2009 to 2016, 118 infants and children with burn injury were admitted to our institution (median age 16 months [IQR = 12.2-20]); 51.7% of them had face burns, 37.3% underwent tracheal intubation, and 30.5% had a PICU stay greater than 7 days. Ventilated patients had a longer PICU stay (13 days [IQR = 8-26] vs 4.5 days [IQR = 2-13]). Both ventilation requirement and TBSA% correlated with PICU stay (r = .955, p < .0001 and r = .335, p = .002, respectively), while ventilation was best related in those >1 week (r = .964, p < .0001 for ventilation, and r = -.079, p = .680, for TBSA%). NIV was introduced in 10 patients, with the aim of shorten the invasive ventilation requirement. As evidenced in our work, mechanical ventilation is frequently needed in burned children admitted to PICU and it is one of the main factors influencing PICU length of stay. No difference was found in terms of PICU length of stay and invasive mechanical ventilation time between children who underwent NIV and children who did not, despite children who underwent NIV had a larger burn surface. NIV can possibly shorten the total invasive ventilation time and related complications.
