Abstract
Appropriate status epilepticus (SE) management is key to minimize admission to the pediatric intensive care unit (PICU). We retrospectively describe 115 children admitted to the PICU of the tertiary-care referral hospital of Padova for seizures, SE, and SE-related complications (59% from second-level hospitals, 41% from the referral hospital) and compare SE management among hospitals. Compared with the referral center, in second-level hospitals, anesthetics were more often administered as first/second drug (P < .001), and intubation was more frequent (P < .001). Intubation was significantly associated with SE onset at home (P = .045) and benzodiazepine-associated respiratory depression (P = .044). There was no association between intubation and SE duration, etiology, PICU length of stay, and morbidity at discharge. In conclusion, adherence to treatment protocols on SE management after the first-line drug differs between referral center and second-level hospitals. Lack of association with SE characteristics and patient's outcome suggests PICU admission could be due to inappropriate invasive management.

Myoclonic super-refractory status epilepticus with favourable evolution in a teenager with FIRES: Is the association of vagus nerve stimulation and cannabidiol effective? Brain Dev 2023; 45:293-299. [PMID: 36725381 DOI: 10.1016/j.braindev.2023.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 01/11/2023] [Accepted: 01/16/2023] [Indexed: 01/31/2023]
Abstract
BACKGROUND Febrile infection-related epilepsy syndrome (FIRES) is a rare and catastrophic clinical syndrome occurring in previously healthy patients. Aetiology is still unknown and outcome usually poor. We describe a case of myoclonic prolonged super refractory status epilepticus (P-SRSE) in FIRES in a patient admitted to the paediatric intensive care unit of Padova, Italy. CASE REPORT A previously healthy 14-year-old girl with onset of myoclonic status epilepticus after a mild febrile illness was admitted to our hospital with a diagnosis of FIRES. Extensive diagnostic work-up was inconclusive. Status epilepticus and electroclinical seizures recurred every time weaning from anaesthetic agents was attempted. Eventually, a vagal nerve stimulator (VNS) was implanted and cannabidiol (CBD) administered, 43 days and 70 days after P-SRSE onset, respectively. Two days after CBD introduction, status epilepticus weaned and the girl rapidly regained complete consciousness showing a brilliant and unexpected recovery. At last follow-up, 12 months later, she is 8-months seizure free on multiple antiseizure medications, has only mild neuropsychological impairment with no neurological and intellective deficit. CONCLUSIONS To our knowledge, this represents a unique case with an extremely favourable evolution with a possible effect of the association of VNS and CBD to traditional antiseizure medications.

Is ketamine infusion effective and safe as an adjuvant of sedation in the PICU? Results from the Ketamine Infusion Sedation Study (KISS). Pharmacotherapy 2022. [PMID: 36567489 DOI: 10.1002/phar.2754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 09/08/2022] [Accepted: 10/11/2022] [Indexed: 12/27/2022]
Abstract
STUDY OBJECTIVE We aimed to evaluate the efficacy and safety of ketamine in ensuring comfort and sparing conventional drugs when used as an adjuvant for analgesia and sedation in the Pediatric Intensive Care Unit (PICU) as a continuous infusion (≥12 h). DESIGN Observational prospective study. SETTING Tertiary-care-center PICU. PATIENTS All consecutive patients <18 years who received ketamine for ≥12 h between January 2019 and July 2021. INTERVENTIONS ketamine infusion for ≥12 h. MEASUREMENTS AND MAIN RESULTS Seventy-seven patients (median age 16 months, Interquartile Range (IQR) 7-43) were enrolled. Twenty-six percent of patients (n = 20) were paralyzed, while 74% (n = 57) were not. The median infusion duration was 90 h (IQR 39-193), with doses between 15 (IQR 15-20) and 30 μg/kg/min (IQR 20-50). At 24 h of ketamine infusion, values of COMFORT-B-Scale (CBS) were significantly lower compared with values pre-ketamine (p < 0.001). Simultaneously, doses/kg/h of opioids and benzodiazepines significantly decreased at 24 h (p < 0.001 and p = 0.002, respectively), while doses/kg/h of propofol (p = 0.500) and dexmedetomidine (p = 0.072) did not significantly change. Seventy-four percent of non-paralyzed patients (42/57) had a decrease in CBS ≥2 points with no increase of concomitant analgosedation drugs. Among paralyzed patients (n = 20), 13 (65%) had no increase of concomitant analgosedation within 24 h after ketamine initiation. Overall, 55/77 (71%) of patients responded to ketamine. The mean and maximum ketamine infusion dosages were significantly higher in the non-responders (p = 0.021 and 0.028, respectively). Eleven patients had adverse events potentially related to ketamine (hypersalivation, systemic hypertension, dystonia/dyskinesia, tachycardia, and agitation) and six patients required intervention (dose reduction, suspension, or pharmacologic therapy). None of the patients developed delirium during ketamine infusion. CONCLUSIONS Ketamine used as a continuous infusion in the PICU might represent a valid strategy to ensure comfort and spare opioids and benzodiazepines in difficult-to-sedate PICU patients. Adverse events are minor and easily reversible. Future study will be needed to investigate long-term outcomes.

Life-sustaining treatment decisions in pediatric intensive care: an Italian survey on ethical concerns. Ital J Pediatr 2021; 47:153. [PMID: 34233717 PMCID: PMC8261393 DOI: 10.1186/s13052-021-01054-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 04/21/2021] [Indexed: 11/16/2022] Open
Abstract
Objectives To investigate how life-sustaining treatment (LST) decisions are made and identify problematic ethical concerns confronted by physicians and nurses in pediatric intensive care within Italy. Methods An 88-question online survey was created, based on a previous qualitative study conducted by this team. The survey was designed to identify how LST decisions were managed; contrasting actual practices with what participants think practices should be. Replies from physicians and nurses were compared, to identify potential inter-professional ethical tensions. The study also identified participants’ principal ethical concerns. Moreover, open-ended questions elicited qualitative perspectives on participants’ views. The survey was pilot-tested and refined before initiation of the study. Results 31 physicians and 65 nurses participated in the study. Participants were recruited from pediatric intensive care units across five Italian cities; i.e., Florence, Milan, Padua, Rome, Verona. Statistically significant differences were identified for (a) virtually all questions contrasting actual practices with what participants think practices should be and (b) 14 questions contrasting physician replies with those of nurses. Physicians and nurses identified the absence of legislative standards for LST withdrawal as a highly problematic ethical concern. Physicians also identified bearing responsibility for LST decisions as a major concern. Qualitative descriptions further demonstrated that these Italian pediatric intensive care clinicians encounter significantly distressing ethical problems in their practice. Conclusions The results of this study highlight a need for the development of (a) strategies for improving team processes regarding LST decisions, so they can be better aligned with how clinicians think decisions should be made, and (b) Italian LST decision-making standards that can help ensure optimal ethical practices.

Abstract
INTRODUCTION Some evidence indicates that exogenous surfactant therapy may be effective in infants with acute viral bronchiolitis, even though more confirmatory data are needed. To date, no large multicentre trials have evaluated the effectiveness and safety of exogenous surfactant in severe cases of bronchiolitis requiring invasive mechanical ventilation (IMV). METHODS AND ANALYSIS This is a multicentre randomised, placebo-controlled, double-blind study, performed in 19 Italian paediatric intensive care units (PICUs). Eligible participants are infants under the age of 12 months hospitalised in a PICU, suffering from severe acute hypoxaemic bronchiolitis, requiring IMV. We adopted a more restrictive definition of bronchiolitis, including only infants below 12 months of age, to maintain the population as much homogeneous as possible. The primary outcome is to evaluate whether exogenous surfactant therapy (Curosurf, Chiesi Pharmaceuticals, Italy) is effective compared with placebo (air) in reducing the duration of IMV in the first 14 days of hospitalisation, in infants suffering from acute hypoxaemic viral bronchiolitis. Secondary outcomes are duration of non-invasive mechanical ventilation in the post-extubation phase, number of cases requiring new intubation after previous extubation within 14 days from randomisation, PICU and hospital length of stay (LOS), duration of oxygen dependency, effects on oxygenation and ventilatory parameters during invasive mechanical respiratory support, need for repeating treatment within 24 hours of first treatment, use of other interventions (eg, high-frequency oscillatory ventilation, nitric oxide, extracorporeal membrane oxygenation), mortality within the first 14 days of PICU stay and before hospital discharge, side effects and serious adverse events. ETHICS AND DISSEMINATION The trial design and protocol have received approval by the Italian National Agency for Drugs (AIFA) and by the Regional Ethical Committee of Verona University Hospital (1494CESC). Findings will be disseminated through publication in peer-reviewed journals, conference/meeting presentations and media. TRIAL REGISTRATION NUMBER Clinicaltrials.gov, issue date 22 May 2019. NCT03959384.

Abstract
Abstract
Background
In the last years air pollution has been linked to an increased risk of several children respiratory pathologies, especially low respiratory tract infections. In more severe cases, the child could be hospitalized in Pediatric Intensive Care Unit (PICU). The present study aims to evaluate the association between the exposure to air pollution and (i) PICU admissions and (ii) hospitalization rates among children with a previous PICU admission.
Methods
PICU admissions due to respiratory diseases were collected from 2010 to 2019 in Padua hospital (Italy) based on a large clinical Italian register. Furthermore, for subjects admitted in 2013, all subsequent hospitalizations have been tracked until 2019 from hospital discharge records. Environmental data were obtained from monitoring stations located within 20 km from the children residence. A conditional logistic regression based on a time-stratified case-crossover design will be performed to evaluate the association between hospital admissions and NO2, PM2.5 and PM10 in aerodynamic diameter.
Results
The registry contains data about more than 30000 PICU admissions, of which around 30 % are of children under one year of age. An increased prevalence for respiratory diseases' admissions, from 18% in 2010 to 24% in 2019 can be observed. More than 400 children were admitted to Padua's PICU in 2013. In the following years, all these subjects experienced at least one hospitalization (median 2, [IQR 1-5]) for more than 2000 hospital admissions from 2014 up to 2019.
Conclusions
Exposure of infants to air pollution could lead to more severe outcome as hospitalization as a result of a vulnerable lung condition that eases virus infections. This condition identifies a particularly frail population. With this approach, an association between air pollution and PICU admissions could be investigated in order to adopt public health policies aimed at safeguarding this frail population.
Key messages
The study would detect an association between air pollution and hospital admissions as severe outcomes in infants and children. Furthermore, this is the first study that would assess if there is an association between these two factors in more frail subjects already hospitalized in a Pediatric Intensive Care Unit.

Case Report: Life-Threatening Macrophage Activation Syndrome With Fulminant Myocarditis Successfully Rescued by High Dose Intravenous Anakinra. Front Pediatr 2020; 8:635080. [PMID: 33537271 PMCID: PMC7848179 DOI: 10.3389/fped.2020.635080] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Accepted: 12/22/2020] [Indexed: 01/20/2023] Open
Abstract
Macrophage activation syndrome (MAS) is a rare, potentially life-threatening, condition triggered by infections or flares in rheumatologic and neoplastic diseases. The mainstay of treatment includes high dose corticosteroids, intravenous immunoglobulins and immunosuppressive drugs although, more recently, a more targeted approach, based on the use of selective cytokines inhibitors, has been reported. We present the case of a two-year-old boy with 1-month history of high degree fever associated with limping gait, cervical lymphadenopathy and skin rash. Laboratory tests showed elevation of inflammatory markers and ferritin. By exclusion criteria, systemic onset Juvenile Idiopathic Arthritis (sJIA) was diagnosed and steroid therapy started. A couple of weeks later, fever relapsed and laboratory tests were consistent with MAS. He was promptly treated with high doses intravenous methylprednisolone pulses and oral cyclosporin A. One day later, he developed an acute myocarditis and a systemic capillary leak syndrome needing intensive care. Intravenous Immunoglobulin and subcutaneous IL-1-antagonists Anakinra were added. On day 4, after an episode of cardiac arrest, venous-arterial extracorporeal membrane oxygenation (VA-ECMO) was started. Considering the severe refractory clinical picture, we tried high dose intravenous Anakinra (HDIV-ANA, 2 mg/Kg q6h). This treatment brought immediate benefit: serial echocardiography showed progressive resolution of myocarditis, VA-ECMO was gradually decreased and definitively weaned off in 6 days and MAS laboratory markers improved. Our case underscores the importance of an early aggressive treatment in refractory life-threatening sJIA-related MAS and adds evidence on safety and efficacy of HDIV-ANA particularly in acute myocarditis needing VA-ECMO support.

Efficacy and safety of dexmedetomidine for prevention of withdrawal syndrome in the pediatric intensive care unit: protocol for an adaptive, multicenter, randomized, double-blind, placebo-controlled, non-profit clinical trial. Trials 2019; 20:710.

Abstract
Background Prolonged treatment with analgesic and sedative drugs in the pediatric intensive care unit (PICU) may lead to undesirable effects such as dependence and tolerance. Moreover, during analgosedation weaning, patients may develop clinical signs of withdrawal, known as withdrawal syndrome (WS). Some studies indicate that dexmedetomidine, a selective α2-adrenoceptor agonist, may be useful to prevent WS, but no clear evidence supports these data. The aims of the present study are to evaluate the efficacy of dexmedetomidine in reducing the occurrence of WS during analgosedation weaning, and to clearly assess its safety. Methods We will perform an adaptive, multicenter, randomized, double-blind, placebo-controlled trial. Patients aged < 18 years receiving continuous intravenous analgosedation treatment for at least 5 days and presenting with clinical conditions that allow analgosedation weaning will be randomly assigned to treatment A (dexmedetomidine) or treatment B (placebo). The treatment will be started 24 h before the analgosedation weaning at 0.4 μg/kg/h, increased by 0.2 μg/kg/h per hour up to 0.8 μg/kg/h (neonate: 0.2 μg/kg/h, increased by 0.1 μg/kg/h per hour up to 0.4 μg/kg/h) and continued throughout the whole weaning time. The primary endpoint is the efficacy of the treatment, defined by the reduction in the WS rate among patients treated with dexmedetomidine compared with patients treated with placebo. Safety will be assessed by collecting any potentially related adverse event. The sample size assuring a power of 90% is 77 patients for each group (total N = 154 patients). The study was approved by the Ethics Committee of the University-Hospital S.Orsola-Malpighi of Bologna on 22 March 2017. Discussion The present trial will allow us to clearly assess the efficacy of dexmedetomidine in reducing the occurrence of WS during weaning from analgosedation drugs. In addition, the study will provide a unique insight into the safety profile of dexmedetomidine. Trial registration ClinicalTrials.gov, NCT03645603. Registered on 24 August 2018.

Predictors of mortality after admission to pediatric intensive care unit in oncohematologic patients without history of hematopoietic stem cell transplantation: A single-center experience. Pediatr Blood Cancer 2019; 66:e27892. [PMID: 31250548 DOI: 10.1002/pbc.27892] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Revised: 05/24/2019] [Accepted: 06/01/2019] [Indexed: 11/08/2022]
Abstract
BACKGROUND Pediatric oncohematologic patients are a high-risk population for clinical deterioration that might require pediatric intensive care unit (PICU) admission. Several studies have described outcomes and mortality predictors for patients post hematopoietic stem cell transplantation (HSCT), but fewer data exist regarding the category of non-HSCT patients. PROCEDURE All oncohematologic non-HSCT patients ≤18 years requiring PICU admission from 1998 to 2015 in our tertiary-care academic hospital were retrospectively evaluated by means of the pediatric hematology-oncology unit database and the Italian PICUs data network database. We assessed the relation between demographic and clinical characteristics and 90-day mortality after PICU admission. RESULTS Of 3750 hospitalized oncohematologic patients, 3238 were non-HSCT and 63 (2%) of them were admitted to the PICU. Patients were mainly affected by hematological malignancies (70%) and mostly were in the induction-therapy phase. The main reasons for admission were respiratory failure (40%), sepsis (25%), and seizures (16%). The median PICU stay was 5 days (range 1-107). The mortality rate at PICU discharge was 30%, and at 90 days it was 35%. Fifty-five percent of deaths happened in the first 2 days of the PICU stay. Cardiac arrest (P = .007), presence of disseminated intravascular coagulation (DIC, P = .007), and acute kidney injury (AKI) at PICU admission (P < .001) and during PICU stay (P = .021) were significant predictors of mortality in the multivariate analysis. Respiratory failure and mechanical ventilation were not associated with mortality. CONCLUSIONS A relatively small percentage of non-HSCT patients required PICU admission, but the mortality rate was still high. Hemodynamic instability, DIC, and AKI, but not respiratory failure, were significant predictors of mortality.

Abstract
INTRODUCTION Children admitted to paediatric intensive care unit (PICU) are at risk of acute kidney injury (AKI). However, few paediatric studies have focused on the identification of factors potentially associated with the development of this condition. The aim of our study was to assess the incidence rate of AKI, identify risk factors, and evaluate clinical outcome in a large sample of critically ill children. METHODS This retrospective observational study was conducted including patients admitted to our PICU from January 2014 to December 2016. AKI was defined according to Kidney Disease: Improving Global Outcome criteria. RESULTS A total of 222 PICU patients out of 811 (27%) had AKI (stage I 39%, stage II 24%, stage III 37%). The most common PICU admission diagnoses in AKI cases were heart disease (38.6%), respiratory failure (16.8%) and postsurgical non-cardiac patients (11%). Hypoxic-ischaemic was the most frequent cause of AKI. Significant risk factors for AKI following multivariate analysis were age >2 months (OR 2.43; 95% CI 1.03-7.87; p = 0.05), serum creatinine at admission >44 µmol/L (OR 2.23; 95% CI 1.26-3.94; p = 0.006), presence of comorbidities (OR 1.84; 95% CI 1.03-3.30; p = 0.04), use of inotropes (OR 2.56; 95% CI 1.23-5.35; p= 0.012) and diuretics (OR 2.78; 95% CI 1.49-5.19; p = 0.001), exposure to nephrotoxic drugs (OR 1.66; 95% CI 1.01-2.91; p= 0.04), multiple organ dysfunction syndrome (OR 2.68; 95% CI 1.43-5.01; p = 0.002), and coagulopathy (OR 1.89; 95% CI 1.05-3.38, p = 0.03). AKI was associated with a significant longer PICU stay (median LOS of 8 days, interquartile range [IQR] 3-16, versus 4 days, IQR 2-8, in non-AKI patients; p < 0.001). The mortality rate resulted tenfold higher in AKI than non-AKI patients (12.6 vs. 1.2%; p < 0.001). CONCLUSIONS The incidence of AKI in critically ill children is high, with an associated increased length of stay and risk of mortality. In the PICU setting, risk factors of AKI are multiple and mainly associated with illness severity.

Abstract
OBJECTIVE To evaluate the health-related quality of life on a very long-term follow-up in patients treated with extracorporeal membrane oxygenation (ECMO) during neonatal and pediatric age. DESIGN Prospective follow-up study. SETTING Pediatric Intensive Care Unit of a tertiary-care University-Hospital. PATIENTS Out of 20 neonates and 21 children treated with ECMO in our center, 24 patients underwent short-term neurological follow-up. Twenty of them underwent long-term neurological follow-up. INTERVENTION Short-term follow-up was performed at 18 months and consisted in clinical evaluation, electroencephalography, and neuroimaging. Long-term follow-up was performed in 2017, at the mean period 19.72 years from ECMO (median 20.75, range 11.50-24.08) and consisted in a standardized questionnaires self-evaluation (PedsQL 4.0 Generic Core Scale) of health-related quality of life and an interviewed about the presence of organ morbidity, school level, or work position. MEASUREMENTS AND MAIN RESULTS Sixty-one percent (25/41) of the patients survived within 30 days after ECMO treatment. Short-term follow-up was performed in 24 patients (1 patient but died before the evaluation): 21 patients (87%) showed a normal neurological status, and 3 developed severe disability. Long-term follow-up was performed in 20 long-term survivors (3 patients were not possible to be contacted and considered lost to follow-up): mean age of patients at long-term follow-up was 21.23 (median 20.96, range 13.33-35.58) years; 90% (18/20) of them have no disability with a complete normal quality of life and 95% have no cognitive impairment. CONCLUSIONS ECMO represents a life-saving treatment for infants and children with respiratory and/or heart failure; survivors show a good quality of life comparable to healthy peers.

Abstract
Background In numerous randomized controlled trials (RCTs) and systematic reviews such as those published by the Cochrane Collaboration, Pelargonium sidoides extract EPs® 7630 was shown to be effective in acute respiratory tract infections (aRTI) in all investigated age-groups. This narrative review focuses on recently published results from RCTs investigating the clinical efficacy and safety of EPs 7630 in children and adolescents with different manifestations of aRTI, in order to present a broader overview and to provide an update on the state of knowledge regarding the use of EPs 7630 in this age-group. Methods The Cochrane review on P. sidoides extract for aRTI published by the Cochrane Collaboration was searched for cited RCTs with EPs 7630 in children and adolescents suffering from aRTI. A PubMed and SCOPUS literature search was performed for publications issued before June 13, 2017 (search terms: children, Pelargonium sidoides, EPs 7630, respiratory). Reference lists of publications found were searched for relevant citations. Results Eight RCTs investigating the application of EPs 7630 in acute bronchitis, acute tonsil-lopharyngitis, and aRTI in the context of chronic preconditions were identified. Results showed a statistically significant improvement of aRTI symptom severity for EPs 7630 as compared to controls. The investigation of EPs 7630 in asthmatic children and adolescents with aRTI demonstrated a significant symptom-alleviating effect and a possibly associated reduction of asthma attacks. In immunocompromised children with acute upper RTI, an alleviating effect of EPs 7630 was shown. All RCTs reviewed reported good safety and tolerability of EPs 7630. Conclusion The P. sidoides extract EPs 7630 is effective and safe for those of pediatric age and may be regarded as an alternative option for the management of aRTI.

Abstract
There is a lack of definitive data on the effective management of acute respiratory distress syndrome (ARDS) in infants and children. The development and validation of the Berlin definition (BD) for ARDS and the Pediatric Acute Lung Injury Consensus Conference (PALICC) recommendations in children represented a major advance in optimizing research and treatment, mainly due to the introduction of a severe ARDS category. Proposed reasons for the lack of consistent results with surfactants in children and infants compared with neonates include different causes, type of lung damage (direct or indirect), timing and mode of administration as well as the type of surfactant used. Secretory phospholipase A2 plays an important role in inflammation and possible dysfunction of surfactants in ARDS. Bronchoalveolar lavage (BAL) with normal saline and surfactant allows the removal of inhaled material, the recruitment of non-ventilating areas and the maintenance of the surfactant pool size. BAL with diluted surfactant allows rapid absorption of the surfactant at the air/liquid interface, which blocks the progression of pathological lung disease and in turn disrupts the inflammatory cycle. Importantly, it is now recognized that the type of surfactant, the time of administration and the method of administration could all play an important role in the management of ARDS, and there is evidence that surfactant is effective and well tolerated in children and infants with ARDS.

Abstract
To describe incidence, causes, and outcomes related to pediatric intensive care unit (PICU) admission for patients undergoing hematopoietic stem cell transplantation (HSCT), we investigated the risk factors predisposing to PICU admission and prognostic factors in terms of patient survival. From October 1998 to April 2015, 496 children and young adults (0 to 23 years) underwent transplantation in the HSCT unit. Among them, 70 (14.1%) were admitted to PICU. The 3-year cumulative incidence of PICU admission was 14.3%. The main causes of PICU admission were respiratory failure (36%), multiple organ failure (16%), and septic shock (13%). The overall 90-day cumulative probability of survival after PICU admission was 34.3% (95% confidence interval, 24.8% to 47.4%). In multivariate analysis, risk factors predisposing to PICU admission were allogeneic HSCT (versus autologous HSCT, P = .030) and second or third HSCT (P = .018). Characteristics significantly associated with mortality were mismatched HSCT (P = .011), relapse of underlying disease before PICU admission (P < .001), acute respiratory distress syndrome at admission (P = .012), hepatic failure at admission (P = .021), and need for invasive ventilation during PICU course (P < .001). Our data indicate which patients have a high risk for PICU admission after HSCT and for dismal outcomes after PICU stay. These findings may provide support for the clinical decision-making process on the opportunity of PICU admission for severely compromised patients after HSCT.

Abstract
In order to better understand the global approach and country differences in physicians' usage, knowledge, and attitudes towards natural remedies and homeopathy in pediatric practice, an online survey involving 582 general pediatricians and general practitioners treating pediatric diseases was conducted in 6 countries. Overall, 17% of the pediatric prescriptions refer to phytotherapy and 15% refer to homeopathic preparations. Natural remedies and homeopathic preparations are more frequently used in upper respiratory tract infections, infant colic, sleep disturbances, and recurrent infections. In the majority of cases, they are used together with chemical drugs. Both treatment options are typically used if parents are concerned about side effects of conventional drugs or prefer natural remedies for themselves. Physicians express high interest in natural remedies and homeopathy; however, their knowledge is variable. Lack of proven efficacy, knowledge on mechanism of action, and information on indications are main factors that limit their usage.

Abstract
INTRODUCTION Status epilepticus (SE) is a life-threatening neurological emergency. SE lasting longer than 120 min and not responding to first-line and second-line antiepileptic drugs is defined as 'refractory' (RCSE) and requires intensive care unit treatment. There is currently neither evidence nor consensus to guide either the optimal choice of therapy or treatment goals for RCSE, which is generally treated with coma induction using conventional anaesthetics (high dose midazolam, thiopental and/or propofol). Increasing evidence indicates that ketamine (KE), a strong N-methyl-d-aspartate glutamate receptor antagonist, may be effective in treating RCSE. We hypothesised that intravenous KE is more efficacious and safer than conventional anaesthetics in treating RCSE. METHODS AND ANALYSIS A multicentre, randomised, controlled, open-label, non-profit, sequentially designed study will be conducted to assess the efficacy of KE compared with conventional anaesthetics in the treatment of RCSE in children. 10 Italian centres/hospitals are involved in enrolling 57 patients aged 1 month to 18 years with RCSE. Primary outcome is the resolution of SE up to 24 hours after withdrawal of therapy and is updated for each patient treated according to the sequential method. ETHICS AND DISSEMINATION The study received ethical approval from the Tuscan Paediatric Ethics Committee (12/2015). The results of this study will be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER NCT02431663; Pre-results.

Abstract
BACKGROUND Errors in are estimated to occur with an incidence of 3.7-16.6% in hospitalized patients. The application of systems for detection of adverse events is becoming a widespread reality in healthcare. Incident reporting (IR) and failure mode and effective analysis (FMEA) are strategies widely used to detect errors, but no studies have combined them in the setting of a pediatric intensive care unit (PICU). AIM The aim of our study was to describe the trend of IR in a PICU and evaluate the effect of FMEA application on the number and severity of the errors detected. METHODS With this prospective observational study, we evaluated the frequency IR documented in standard IR forms completed from January 2009 to December 2012 in the PICU of Woman's and Child's Health Department of Padova. On the basis of their severity, errors were classified as: without outcome (55%), with minor outcome (16%), with moderate outcome (10%), and with major outcome (3%); 16% of reported incidents were 'near misses'. We compared the data before and after the introduction of FMEA. RESULTS Sixty-nine errors were registered, 59 (86%) concerning drug therapy (83% during prescription). Compared to 2009-2010, in 2011-2012, we noted an increase of reported errors (43 vs 26) with a reduction of their severity (21% vs 8% 'near misses' and 65% vs 38% errors with no outcome). CONCLUSION With the introduction of FMEA, we obtained an increased awareness in error reporting. Application of these systems will improve the quality of healthcare services.

Abstract
AIM Critically ill children can develop withdrawal syndrome after prolonged analgesia and sedation in a paediatric intensive care unit (PICU), when treatment is stopped abruptly or reduced quickly. The aim of this study was to evaluate the incidence of withdrawal syndrome in patients after three or more days of analgesic or sedative drug therapy, using a validated scale. We also analysed the association between withdrawal syndrome and the patients' outcome and factors related to analgesia and sedation treatment. METHODS This prospective observational study analysed 89 periods of weaning from analgesia and sedation in 60 children between October 2010 and October 2011. Of these, 65% were less than six months old and 45% were admitted to the PICU after heart surgery. Withdrawal syndrome was assessed using the Withdrawal Assessment Tool-1 (WAT-1) scale. RESULTS The incidence of withdrawal syndrome was 37%, and the only variable that predicted its presence was the highest administered dose of benzodiazepine. The duration of weaning, Sophia Observational Withdrawal Symptom scale score and nurse judgment were also associated with positive WAT-1 scores. CONCLUSION Withdrawal syndrome should be considered after three or more days of analgesic or sedative treatment. A high dose of benzodiazepine increases the risk of developing withdrawal symptoms.

Abstract
Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation syndrome (ROHHADS) is a rare, but potentially lethal, pediatric disorder. To date, nearly 80 patients have been reported in the literature; however, the etiopathogenesis is still unclear and debated. Both genetic and paraneoplastic or immune-mediated causes have been supposed to be involved in this syndrome. Nonetheless, at this time, a diagnostic biomarker is not available and diagnosis is based exclusively on clinical criteria. Aiming to establish the immune-mediated pathogenesis, we report 2 children with a clinical picture consistent with ROHHADS and whose cerebrospinal fluid analysis disclosed an intrathecal synthesis of oligoclonal bands. Even if many aspects remain to be explained, this finding suggests that ROHHADS could share similar pathogenetic mechanisms with other immune-mediated central nervous system disorders, and even more important, it might pave the way to a therapeutic chance for these patients by means of immunotherapy.

Abstract
We present a dramatic case of a patient presenting with disseminated intravascular coagulation related to meningococcal sepsis who developed heparin-induced thrombocytopenia following heparin administration during continuous renal replacement therapy. Association of these two prothrombotic conditions led to severe limbs ischemia and finally to bilateral legs amputation. We stress the importance of suspect heparin-induced thrombocytopenia in intensive care unit patients, especially when an improvement of other coagulation parameters is observed, and heparin therapy was started.

Abstract
UNLABELLED High-flow nasal cannula (HFNC) is a widely used ventilatory support in children with bronchiolitis in the intensive care setting. No data is available on HFNC use in the general pediatric ward. The aim of this study was to evaluate the feasibility of HFNC oxygen therapy in infants hospitalized in a pediatric ward for moderate-severe bronchiolitis and to assess the changes in ventilatory parameters before and after starting HFNC support. This prospective observational pilot study was carried out during the bronchiolitis season 2011-2012 in a pediatric tertiary care academic center in Italy. Interruptions of HFNC therapy and possible side effects or escalation to other forms of respiratory support were recorded. Oxygen saturation (SpO2), end-tidal carbon dioxide (ETCO2), and respiratory rate (RR), measured for a baseline period of 1 h before and at specific time intervals in 48 h after the start of HFNC were recorded. Twenty-seven infants were included (median age 1.3 months; absolute range 0.3-8.5). No adverse events, no premature HFNC therapy termination, and no escalation to other forms of respiratory support were recorded. Median SpO2 significantly increased by 1-2 points after changing from standard oxygen to HFNC (p <0.001). Median ETCO2 and RR rapidly decreased by 6-8 mmHg and 13-20 breaths per minute, respectively, in the first 3 h of HFNC therapy (p <0.001) and remained steady thereafter. CONCLUSIONS Use of HFNC for oxygen administration is feasible for infants with moderate-severe bronchiolitis in a general pediatric ward. In these children, HFNC therapy improves oxygen saturation levels and seems to be associated with a decrease in both ETCO2 and RR.

Abstract
BACKGROUND No strong recommendation was reported in management analgesia and sedation of critically ill children. The present study was performed to describe the current practice of analgesia and sedation in Pediatric Italian Intensive Care Units, in order to evaluate the adherence to last published pediatric guidelines. METHODS A questionnaire was sent to 24 Italian Paediatric Intensive Care Units during 2010. RESULTS One Hundred percent of contacted centers returned the filled form. All Pediatric Italian Intensive Care Units used the same combination (opioid plus benzodiazepine); 50% of centers referred to regularly monitor the level of sedation, but only 37% of them used validate tools. Withdrawal syndrome was regularly monitored in 25% of contacted Pediatric Italian Intensive Care Units; Finnegan scale was the only adopted scale. CONCLUSION National pediatric intensivists identified the same drug strategy to obtain analgesia and sedation in their patients, according to last published guidelines. Assessment of analgesia and sedation was more diffuse but not regularly performed and different methods were used. Withdrawal syndrome was monitored in a minority of contacted centres. Considering our data the practice of analgesia and sedation in Italian Pediatric Intensive Care Units is improved but not yet completely adherent to last international recommendations.

Abstract
Chiari malformation type 2 is characterized by hindbrain protrusion and a constellation of supratentorial malformations. Chiari malformation type 2 is thought to be causally related to myelomeningocele due to intrauterine cerebrospinal fluid overdrainage. This relationship is so strong that it has become a rule. A 14-year-old girl affected by mental retardation, spastic triparesis, and epilepsy is presented. Brain magnetic resonance imaging disclosed a severe Chiari malformation type 2, whereas spine magnetic resonance imaging was unremarkable. The authors discuss previous literature describing rare cases of Chiari malformation type 2 without open spinal dysraphism and the relevance of concomitant, sometimes overlooked, neuroimaging findings, underlying how exceptions might be hurdles but might also eventually strengthen the rules.

Abstract
BACKGROUND The aim of this paper was to monitor comfort in pediatric critical ill patients which is necessary to adequate analgesic and sedative therapy. The primary objective of this prospective observational study was to measure the level of sedation in a Pediatric Intensive Care Unit (PICU) of a tertiary care Hospital, using Comfort Behavioural Scale (CBS) and Bispectral Index (BIS), evaluating the agreement between these tools; secondly we analyzed the correlation of an adequate level of sedation and patient's outcome. METHODS We enrolled 46 patients, mechanically ventilated for almost 12 hours, monitored at a basal level and during a stimulus (tracheal suctioning). As outcome variables we analyzed: length of ventilation and PICU stay, duration of sedative therapy and weaning, time between beginning of sedative administration and start of weaning, presence of infection. RESULTS Twenty-six percent (doctor CBS score), 34.8% (nurse CBS score) and 73.9% (BIS) of our population were found adequately sedated; none state of undersedation was reported. During the stimulus the percentage of adequately sedated patients according to CBS became 78.2%. CBS level of agreement versus BIS was weak. No significative difference was found between doctor and nurse CBS score. Length of PICU stay and duration of sedative administered were significant shorter in patients adequately sedated at Bispectral Index monitoring; no outcome variable resulted significant looking at CBS score. CONCLUSION Our data support the risk of oversedation in critically ill patients and the difference between CBS and BIS, especially in evaluating light oversedation state. The presence of an excessive level of sedation evaluated by BIS was associated with duration of hospitalization and sedative administration.

Amiodarone impairs trafficking through late endosomes inducing a Niemann-Pick C-like phenotype. Biochem Pharmacol 2011; 82:1234-49.

Abstract
Patients treated with amiodarone accumulate lysobisphosphatidic acid (LBPA), also known as bis(monoacylglycero)phosphate, in airway secretions and develop in different tissues vacuoles and inclusion bodies thought to originate from endosomes. To clarify the origin of these changes, we studied in vitro the effects of amiodarone on endosomal activities like transferrin recycling, Shiga toxin processing, ESCRT-dependent lentivirus budding, fluid phase endocytosis, proteolysis and exosome secretion. Furthermore, since the accumulation of LBPA might point to a broader disturbance in lipid homeostasis, we studied the effect of amiodarone on the distribution of LBPA, unesterified cholesterol, sphingomyelin and glycosphyngolipids. Amiodarone analogues were also studied, including the recently developed derivative dronedarone. We found that amiodarone does not affect early endosomal activities, like transferrin recycling, Shiga toxin processing and lentivirus budding. Amiodarone, instead, interferes with late compartments of the endocytic pathway, blocking the progression of fluid phase endocytosis and causing fusion of organelles, collapse of lumenal structures, accumulation of undegraded substrates and amassing of different types of lipids. Not all late endocytic compartments are affected, since exosome secretion is spared. These changes recall the Niemann-Pick type-C phenotype (NPC), but originate by a different mechanism, since, differently from NPC, they are not alleviated by cholesterol removal. Studies with analogues indicate that basic pKa and high water-solubility at acidic pH are crucial requirements for the interference with late endosomes/lysosomes and that, in this respect, dronedarone is at least as potent as amiodarone. These findings may have relevance in fields unrelated to rhythm control.

Abstract
Amiodarone interferes with the endocytic pathway, inhibits proteolysis, and causes the formation of vacuoles, but uptake and intracellular distribution of the drug, origin of vacuoles, and functional consequences of amiodarone accumulation remain unclear. Our objective was to study amiodarone uptake, clarify the origin of vacuoles, and investigate the effect of amiodarone on the life cycle of the coronavirus responsible for the Severe Acute Respiratory Syndrome (SARS), which, to enter cells, relies on the proteolytic cleavage of a viral spike protein by the endosomal proteinase cathepsin L. Using alveolar macrophages, we studied uptake of (125)I-amiodarone and (125)I-B2, an analog lacking the lateral group diethylamino-beta-ethoxy, and analyzed the effects of amiodarone on the distribution of endosomal markers and on the uptake of an acidotropic dye. Furthermore, using Vero cells, we tested the impact of amiodarone on the in vitro spreading of the SARS coronavirus. We found that (1) amiodarone associates with different cell membranes and accumulates in acidic organelles; (2) the diethylamino-beta-ethoxy group is an important determinant of uptake; (3) vacuoles forming upon exposure to amiodarone are enlarged late endosomes; (4) amiodarone inhibits the spreading in vitro of SARS coronavirus; and (5) trypsin cleavage of the viral spike protein before infection, which permits virus entry through the plasma membrane, does not impair amiodarone antiviral activity. We conclude that amiodarone alters late compartments of the endocytic pathway and inhibits SARS coronavirus infection by acting after the transit of the virus through endosomes.

Abstract
Amiodarone (AMI) is a potent antiarrhythmic agent; however, its clinical use is limited due to numerous side effects. In order to investigate the structure--cytotoxicity relationship, AMI analogues were synthesized, and then, using rabbit alveolar macrophages, were tested for viability and for the ability to interfere with the degradation of surfactant protein A (SP-A) and with the accumulation of an acidotropic dye. Our data revealed that modification of the diethylamino-beta-ethoxy group of the AMI molecule may affect viability, the ability to degrade SP-A and vacuolation differently. In particular, PIPAM (2d), an analogue with a piperidyl moiety, acts toward the cells in a similar manner to AMI, but is less toxic. Thus, it would be possible to reduce the cytotoxicity of AMI by modifying its chemical structure.

This report presents the long-term (36 months) neurologic outcome in 12 neonates and 9 children who survived after extracorporeal membrane oxygenation and attempts to identify its prognostic indicators through a prospective study in the pediatric intensive care unit of a university hospital. Outcome assessment, neurodevelopmental tests, electroencephalogram, auditory evoked potentials, visual evoked potentials, and somatosensory evoked potentials, cerebral sonography, or cerebral tomography were evaluated at the end of bypass and at 6, 12, 24, and 36 months after extracorporeal membrane oxygenation. "Before extracorporeal membrane oxygenation" variables (oxygenation index, pH, oxygen arterial partial pressure) and "during extracorporeal membrane oxygenation" variables (pH, oxygen arterial partial pressure, duration of bypass, clotting activated time, electroencephalogram) were also analyzed. A negative neurologic outcome (Glasgow Outcome Score different from "good recovery" or neurodevelopmental score less than 70) 12 months after extracorporeal membrane oxygenation was documented in 8.3% of neonates and in 30% of children who survived. There was no further change in subsequent evaluations (24 and 36 months follow-up). The most abnormal electroencephalogram during extracorporeal membrane oxygenation, the first electroencephalogram, neuroimaging score, and somatosensory evoked potentials after extracorporeal membrane oxygenation treatment were associated with negative neurologic outcome. The study documented that neonates and children treated with extracorporeal membrane oxygenation require long-term follow-up; electroencephalogram, neuroimaging score, and somatosensory evoked potentials have prognostic value for abnormal neurologic outcome.

Abstract
Human surfactant protein C (hSP-C(1-197)) is synthesized as a 197 amino acid proprotein and cleaved to a mature 3.7 kD form. Although interstitial lung disease in patients with mutations of the hSP-C gene is becoming increasingly recognized, the mechanisms linking molecular events with clinical pathogenesis are not fully defined. We describe a full-term infant with respiratory insufficiency associated with a spontaneous heterozygous mutation resulting in a substitution of lysine for glutamic acid at position 66 (= E66K) of the proximal hSP-C COOH flanking propeptide. Lung histology and biochemical studies of the index patient (hSP-C(E66K)) revealed nonspecific interstitial pneumonia, increased alveolar total phospholipid lacking phosphatidylglycerol, and increased surfactant protein A. Localization of proSP-C from lung sections prepared from this patient using immunofluorescence and immunogold electron microscopy revealed abnormal proSP-C staining in endosomal-like vesicles of type II cells distinct from SP-B. To evaluate the effect of the E66K substitution on intracellular trafficking of proSP-C, fusion proteins consisting of enhanced green fluorescent protein (EGFP) and hSP-C(1-197) (wild type) or mutant hSP-C(E66K) were generated and transfected into A549 cells. EGFP/hSP-C(1-197) was expressed within CD-63-positive, EEA-1-negative vesicles, whereas EGFP/hSP-C(E66K) localized to EEA-1 positive vesicles. The E66K substitution is representative of a new class of SP-C mutation associated with interstitial lung disease that is diverted from the normal biosynthetic pathway. We propose that, similar to other storage disorders, lung injury results from induction of a toxic gain of function induced by the mutant product that is subject to genetic modifiers and environmental influences.

Abstract
Amiodarone, an antiarrhythmic drug toxic toward the lung, is metabolized through sequential modifications of the diethylaminoethoxy group to mono- N-desethylamiodarone (MDEA), di- N-desethylamiodarone (DDEA), and amiodarone-EtOH (B2-O-EtOH), whose effects on lung cells are unclear. To clarify this, we exposed rabbit alveolar macrophages to analogs with different modifications of the diethylaminoethoxy group and then searched for biochemical signs of cell damage, formation of vacuoles and inclusion bodies, and interference with the degradation of surfactant protein A, used as a tracer of the endocytic pathway. The substances studied included MDEA, DDEA, and B2-O-EtOH, analogs with different modifications of the diethylaminoethoxy group, fragments of the amiodarone molecule, and the antiarrhythmic agents dronedarone (SR-33589) and KB-130015. We found the following: 1) MDEA, DDEA, and B2-O-EtOH rank in order of decreasing toxicity toward alveolar macrophages, indicating that dealkylation and deamination of the diethylaminoethoxy group represent important mechanisms of detoxification; 2) dronedarone has greater, and KB-130015 has smaller, toxicity than amiodarone toward alveolar macrophages; and 3) the benzofuran moiety, which is toxic to liver cells, is not directly toxic toward alveolar macrophages.

Abstract
The coagulation disturbance, typical of septic conditions, is associated to a reduction of clotting factors in plasma with an "acquired" deficiency (from consumption) of protein C. As observed with "purpura fulminans" in neonates affected by congenital protein C deficiency, administration of protein C concentrate has proved to reduce thrombotic manifestations and to improve morbidity and mortality of children with septic shock. The Protein C concentrate is presently utilized as a therapy for patients with a congenital deficiency of protein C and several papers in the literature support the efficacy of protein C concentrate in the treatment of children with meningococcus septicemia, with the aim of correcting the acquired protein C deficiency often seen in septic conditions and shown to be strongly correlated to a higher morbidity and mortality. Protein C, given as a plasma concentrate, can exert its therapeutic actions only after activation once in the blood stream: clinical trials with the use of protein C concentrate failed to show any increased risk of bleeding or related disorders. At our PICU 8 children, with sepsis, septic shock and purpura have been treated with protein C concentrate (Ceprotin); because the plasma protein C level was lower than the normal range (mean value 0.32 IU/ml, range 0.11-0.6 IU/ml). Six children have shown a rapid response to all therapeutic efforts and survived without sequelae and two are died. No adverse reaction was observed during and after Ceprotin administration to all patients.

Abstract
Amiodarone may induce lung damage by direct toxicity or indirectly through inflammation. To clarify the mechanism of direct toxicity, we briefly exposed rabbit alveolar macrophages to amiodarone and analyzed their morphology, synthesis, and degradation of dipalmitoylphosphatidylcholine (DPPC); distribution of lysosomal enzymes; and uptake of diphtheria toxin and surfactant protein (SP) A used as tracers of the endocytic pathway. Furthermore, in newborn rabbits, we studied the clearance of DPPC and SP-A instilled into the trachea together with increasing amounts of amiodarone. We found that in vitro amiodarone decreases the surface density of mitochondria and lysosomes while increasing the surface density of inclusion bodies, increases the incorporation of choline into DPPC, modifies the distribution of lysosomal enzymes, and does not affect the uptake and processing of diphtheria toxin but inhibits the degradation of SP-A. In vivo amiodarone inhibits the degradation of SP-A but not of DPPC. We conclude that the acute exposure to amiodarone perturbs the endocytic pathway acting after the early endosomes, alters the traffic of lysosomal enzymes, and interferes with the turnover of SP-A.

Abstract
Flow-volume loop evaluation yields considerable diagnostic information about adult patients with upper airway obstruction. No conclusive data support the reliability of this method in young children with noisy breathing. We used analysis of flow-volume loops at tidal breathing (TB-FV) as a first diagnostic approach to young children presenting with persistent noisy breathing (chronic stridor and/or wheezing). Flexible fiberoptic bronchoscopy was performed to establish a conclusive diagnosis and was used to verify the accuracy of the preliminary functional localization of the airway obstruction causing noisy breathing. The physician conducting pneumotachography was blinded to the bronchoscopic findings in the study, and the investigators conducting bronchoscopy were blinded to the pneumotachographic findings. Through a 6-yr period, 113 consecutive young children (ranging in age from 15 to 48 mo) with noisy breathing were enrolled in the study. Three morphologically abnormal TB-FV patterns, as compared with the normal round-shaped TB-FV loops obtained with 15 healthy children, were identified in 110 patients. A TB-FV pattern of inspiratory fluttering was found in 26 subjects and in the first 3 yr of the study was always associated with an endoscopic diagnosis of isolated laryngomalacia. Subsequently, this pattern was used to diagnose isolated laryngomalacia in 18 other infants, in whom endoscopy was avoided. Of infants with endoscopic evidence of airway obstruction ranging from the glottis to the mainstem bronchi (49 subjects), all but three showed a TB-FV loop pattern characterized by expiratory-limb flattening. A concave expiratory loop, with early expiratory peak flow and low flow at low volume, was invariably associated with peripheral bronchoconstriction, without endoscopic evidence of anatomic abnormalities (20 cases). In conclusion, TB- FV loop analysis is a noninvasive, accurate method of establishing the site of airway obstruction in young children with recurrent stridor and/or wheezing. Clinical use of this method may provide interesting pathophysiologic information and may be useful in addressing the diagnostic management of such children.

Abstract
Before being considered for a cystic fibrosis (CF) gene therapy trial, any gene delivery agent must be able to show that it produces low levels of toxicity as well as being able to protect the DNA from nuclease degradation. Here we show that complexes of linear polyethylenimine (L-PEI) and DNA can repeatedly be administered to animals (up to 21 consecutive days) without eliciting an immune response against PEI/DNA particles or inducing toxic side effects due to accumulation of PEI in the lungs. However, the host response to the exogenous protein resulted in some decrease of expression. PEI-mediated transfection was unaffected by treatment of the complexes with DNase (frequently used to reduce the viscosity of lung secretions in CF patients). Taken together, these properties make L-PEI a valuable vector for gene therapy of CF.

Abstract
This paper examines the removal from the airways of Curosurf, a commercial surfactant derived from porcine lungs, administered at pharmacological concentrations to newborn or adult animals. Curosurf was labelled by the addition of radioactive dipalmitoyl phosphatidylcholine (DPPC) and administered intratracheally to newborn and adult rabbits at a dose of 200 mg x kg(-1) body weight. The disappearance of DPPC from the airways and its appearance in alveolar macrophages, lung parenchyma, lamellar bodies, serum, liver, kidneys and brain was then studied for 24-48 h. The in vitro degradation of Curosurf DPPC by alveolar macrophages was also studied. During the first 3 h after instillation, large amounts of Curosurf left the airways and became associated with tissue, indicating that it mixed rapidly with the endogenous pools of surfactant. A fraction of administered DPPC became associated with the lamellar bodies, suggesting that Curosurf can be recycled. Curosurf administration did not stop the secretion of endogenous surfactant. Very little intact radioactive DPPC could be recovered at any time in alveolar macrophages, however, macrophages have the ability, in vitro, to degrade Curosurf. Newborn rabbits lose Curosurf from the lungs at a slower rate than adult rabbits. One and two days after instillation, organic extracts from the liver, kidney, brain and serum contained small but measurable amounts of radioactivity. These results indicate that Curosurf rapidly enters the pathways of surfactant metabolism and that alveolar macrophages may play an important role in the catabolism of Curosurf.

Abstract
The aim of this study was to evaluate the effect of inhaled nitric oxide (NO) in newborns with acute hypoxaemic respiratory failure and the impact of this NO therapy on survival and the need for extracorporeal membrane oxygenation (ECMO). A cohort of newborns with a gestational age of > or = 34 weeks and an oxygenation index (OI) > 25 were prospectively evaluated. Patients were given NO at an initial dose of 10 parts per million (ppm). Oxygenation parameters were evaluated prior and during NO inhalation. From January 1994 to December 1996, 20 infants were enrolled in the study. Based upon their outcome, patients were divided into two groups: survivors with no need for ECMO, group A (n=8) and survivors requiring ECMO or nonsurvivors, group B (n=12). All infants approached or met ECMO criteria before NO inhalation. Eight patients (40%) were successfully managed with NO and conventional treatment (group A). Newborns in this group showed a rapid and sustained improvement of systemic oxygenation during NO inhalation. Mean arterial oxygen tension (Pa,O2) increased significantly from 4.5 kPa (34 mmHg) (95% confidence interval (95% CI) 1.9-7.1 kPa (14.4-53.7 mmHg)) to 10.1 kPa (75.7 mmHg) (95% CI 6.5-13.6 kPa (49.1-1023 mmHg)) after 1 h and was 9.0 kPa (67.7 mmHg) (95% CI 7.1-11.0 kPa (53.1-82.4 mmHg)) at 24 h. Conversely, none of the oxygenation parameters improved in the 12 patients who ultimately required ECMO or died (group B). The results indicate that inhaled nitric oxide can improve systemic oxygenation in newborns with acute respiratory failure and may reduce the need for extracorporeal membrane oxygenation support in candidates. Lack of a rapid response to nitric oxide may be an early predictor of unfavourable short-term outcome, prompting a move towards alternative treatments.

Abstract
Nonviral vectors might represent a safe alternative to adenovirus for gene therapy of lung disorders, in particular cystic fibrosis (CF). Cationic lipids have been shown to correct the CF defect both in vitro and in vivo, but more efficient vectors are needed to improve the low gene transfer efficiency. Here, we show that the cationic polymer ExGen 500, a linear polyethylenimine derivative, is more efficient than cationic lipids in transferring reporter genes to lung epithelial cells in vitro. In vivo ExGen 500 was able to mediate gene transfer into both newborn and adult rabbit lungs with comparable efficiencies. The best levels of transfection were obtained using neutral complexes. Under such conditions, luciferase activities corresponding to about 10(3) RLU/10 s/mg of protein were reproducibly obtained 2 days after transfection throughout the four lung lobes of newborn and adult rabbits. A nlslacZ reporter gene showed transfected cells around the lumen of large and small bronchi. No signs of acute toxicity (inflammation, cellular infiltration etc) were detected by direct histopathological analysis. Within 1 week after instillation, transgene expression decreased by two orders of magnitude.

Abstract
Advance in the science and technology of neonatal and pediatric critical care have resulted in improved outcome for high risk newborn and children. Effective interhospital transport programmes are necessary for the appropriate use of resources and has become an integral component of regionalized perinatal care. It is now well established that use of an organized neonatal and pediatric transport team results in a fall in mortality and morbidity of infant. The American College of Obstetrician and Gynecologist and, recently, American Academy of Pediatrics published guidelines and recommendations for safe interhospital transfer of neonates, infants and children. Training of personnel, selection of equipment, organization and communication between hospitals are critical elements of a successful transport system. We present an overview of the role, principles and operating procedures of such neonatal-pediatric transport team and the basis of clinical stabilization before and during transfer. We also discuss data of the first 17 month experience of the Neonatal-Pediatric Transport Service of the Department of Pediatrics, University of Padua.

Abstract
Pediatric intensive care units (PICUs) have been developed to provide intensive care for children between post-neonatal age and adolescence. These units have largely been developed in North America, mainly in tertiary hospitals. In Italy, critically ill children are still often nursed on adult ICU's, where medical and nursing staff often lack pediatric training. Here we report the first 5-year experience of the multidisciplinary PICU developed at the Department of Pediatrics, University of Padua, focusing on PICU and patients characteristics, as well as on the evaluation of outcome by means of the Pediatric Risk of Mortality (PRISM) score.
