International Consensus Criteria for Pediatric Sepsis and Septic Shock

Importance

Sepsis is a leading cause of death among children worldwide. Current pediatric-specific criteria for sepsis were published in 2005 based on expert opinion. In 2016, the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defined sepsis as life-threatening organ dysfunction caused by a dysregulated host response to infection, but it excluded children.

Objective

To update and evaluate criteria for sepsis and septic shock in children.

Evidence Review

The Society of Critical Care Medicine (SCCM) convened a task force of 35 pediatric experts in critical care, emergency medicine, infectious diseases, general pediatrics, nursing, public health, and neonatology from 6 continents. Using evidence from an international survey, systematic review and meta-analysis, and a new organ dysfunction score developed based on more than 3 million electronic health record encounters from 10 sites on 4 continents, a modified Delphi consensus process was employed to develop criteria.

Findings

Based on survey data, most pediatric clinicians used sepsis to refer to infection with life-threatening organ dysfunction, which differed from prior pediatric sepsis criteria that used systemic inflammatory response syndrome (SIRS) criteria, which have poor predictive properties, and included the redundant term, severe sepsis. The SCCM task force recommends that sepsis in children be identified by a Phoenix Sepsis Score of at least 2 points in children with suspected infection, which indicates potentially life-threatening dysfunction of the respiratory, cardiovascular, coagulation, and/or neurological systems. Children with a Phoenix Sepsis Score of at least 2 points had in-hospital mortality of 7.1% in higher-resource settings and 28.5% in lower-resource settings, more than 8 times that of children with suspected infection not meeting these criteria. Mortality was higher in children who had organ dysfunction in at least 1 of 4-respiratory, cardiovascular, coagulation, and/or neurological-organ systems that was not the primary site of infection. Septic shock was defined as children with sepsis who had cardiovascular dysfunction, indicated by at least 1 cardiovascular point in the Phoenix Sepsis Score, which included severe hypotension for age, blood lactate exceeding 5 mmol/L, or need for vasoactive medication. Children with septic shock had an in-hospital mortality rate of 10.8% and 33.5% in higher- and lower-resource settings, respectively.

Conclusions and Relevance

The Phoenix sepsis criteria for sepsis and septic shock in children were derived and validated by the international SCCM Pediatric Sepsis Definition Task Force using a large international database and survey, systematic review and meta-analysis, and modified Delphi consensus approach. A Phoenix Sepsis Score of at least 2 identified potentially life-threatening organ dysfunction in children younger than 18 years with infection, and its use has the potential to improve clinical care, epidemiological assessment, and research in pediatric sepsis and septic shock around the world.

Italian pediatric intensive care units admitting critically ill cancer children: results from a national survey

BACKGROUND

Pediatric patients affected by oncologic disease have a significant risk of clinical deterioration that requires admission to the intensive care unit. This study reported the results of a national survey describing the characteristics of Italian onco-hematological units (OHUs) and pediatric intensive care units (PICUs) that admit pediatric patients, focusing on the high-complexity treatments available before PICU admission, and evaluating the approach to the end-of-life (EOL) when cared in a PICU setting.

METHODS

A web-based electronic survey has been performed in April 2021, involving all Italian PICUs admitting pediatric patients with cancer participating in the study.

RESULTS

Eighteen PICUs participated, with a median number of admissions per year of 350 (IQR 248-495). Availability of Extracorporeal Membrane Oxygenation therapy and the presence of intermediate care unit are the only statistically different characteristics between large or small PICUs. Different high-level treatments and protocols are performed in OHUs, non depending on the volume of PICU. Palliative sedation is mainly performed in the OHUs (78%), however, in 72% it is also performed in the PICU. In most centers protocols that address EOL comfort care and treatment algorithms are missing, non depending on PICU or OHU volume.

CONCLUSIONS

A non-homogeneous availability of high-level treatments and in OHUs is described. Moreover, protocols addressing EOL comfort care and treatment algorithms in palliative care are lacking in many centers.

UPDATE - 2022 Italian guidelines on the management of bronchiolitis in infants

Bronchiolitis is an acute respiratory illness that is the leading cause of hospitalization in young children. This document aims to update the consensus document published in 2014 to provide guidance on the current best practices for managing bronchiolitis in infants. The document addresses care in both hospitals and primary care. The diagnosis of bronchiolitis is based on the clinical history and physical examination. The mainstays of management are largely supportive, consisting of fluid management and respiratory support. Evidence suggests no benefit with the use of salbutamol, glucocorticosteroids and antibiotics with potential risk of harm. Because of the lack of effective treatment, the reduction of morbidity must rely on preventive measures. De-implementation of non-evidence-based interventions is a major goal, and educational interventions for clinicians should be carried out to promote high-value care of infants with bronchiolitis. Well-prepared implementation strategies to standardize care and improve the quality of care are needed to promote adherence to guidelines and discourage non-evidence-based attitudes. In parallel, parents' education will help reduce patient pressure and contribute to inappropriate prescriptions. Infants with pre-existing risk factors (i.e., prematurity, bronchopulmonary dysplasia, congenital heart diseases, immunodeficiency, neuromuscular diseases, cystic fibrosis, Down syndrome) present a significant risk of severe bronchiolitis and should be carefully assessed. This revised document, based on international and national scientific evidence, reinforces the current recommendations and integrates the recent advances for optimal care and prevention of acute bronchiolitis.

Evaluation of saliva and nasopharyngeal swab sampling for genomic detection of SARS-CoV-2 in children accessing a pediatric emergency department during the second pandemic wave

SARS-CoV-2 infection is mainly detected by multiplex real-time RT-PCR from upper respiratory specimens, which is considered the gold-standard technique for SARS-CoV-2 infection diagnosis. A nasopharyngeal (NP) swab represents the clinical sample of choice, but NP swabbing can be uncomfortable to the patients, especially for pediatric-age participants, requires trained healthcare personnel, and may generate an aerosol, increasing the intrinsic exposure risk of healthcare workers. The objective of this study was to compare paired NP and saliva samples (SS) collected from pediatric patients to evaluate whether the saliva collection procedure may be considered a valuable alternative to the classical NP swab (NPS) sampling in children. In this study, we describe a SARS-CoV-2 multiplex real-time RT-PCR protocol for SS, comparing the results with the paired NPS specimens from 256 pediatric patients (mean age 4.24 ± 4.40 years) admitted to the hospital emergency room of Azienda Ospedaliera Universitaria Integrata (AOUI), Verona, and randomly enrolled between September 2020 and December 2020. The saliva sampling demonstrated consistent results when compared to NPS use. The SARS-CoV-2 genome was detected in 16 out of 256 (6.25%) NP samples, among which 13 (5.07%) were positive even when paired SS were analyzed. Moreover, SARS-CoV-2-negative NPS and SS were consistent, and the overall concordances between NPS and SS were detected in 253 out of 256 samples (98.83%). Our results suggest that saliva samples may be considered a valuable alternative to NPS for SARS-CoV-2 direct diagnosis with multiplex real-time RT-PCR in pediatric patients.

KETASER01 protocol: What went right and what went wrong

Objective

To discuss the results of the KETASER01 trial and the reasons for its failure, particularly in view of future studies.

Methods

KETASER01 is a multicenter, randomized, controlled, open‐label, sequentially designed, non‐profit Italian study that aimed to assess the efficacy of ketamine compared with conventional anesthetics in the treatment of refractory convulsive status epilepticus (RCSE) in children.

Results

During the 5‐year recruitment phase, a total of 76 RCSEs treated with third‐line therapy were observed in five of the 10 participating Centers; only 10 individuals (five for each study arm; five females, mean age 6.5 ± 6.3 years) were enrolled in the KETASER01 study. Two of the five patients (40%) in the experimental arm were successfully treated with ketamine and two of the five (40%) children in the control arm, where successfully treated with thiopental. In the remaining six (60%) enrolled patients, RCSE was not controlled by the randomized anesthetic(s).

Significance

The KETASER01 study was prematurely halted due to low eligibility of patients and no successful recruitment. No conclusions can be drawn regarding the objectives of the study. Here, we discuss the KETASER01 results and critically analyze the reasons for its failure in view of future trials.

Impact of Aortic Diameter Measurements at Three Anatomical Landmarks on Left Ventricular Output Calculation in Neonates

OBJECTIVES

To assess reproducibility and accuracy of left ventricular output (LVO) quantifications in neonates, when left ventricular outflow tract diameter (LVOTD) was measured at the hinges of the aortic valve (AV), at the aortic sinus (AS), and at the sinotubular junction (STJ).

METHODS

This was an observational study. In the first cohort of very preterm neonates, we assessed intraobserver and interobserver repeatability of LVOTD measured at the AV, AS, and STJ and of the corresponding LVO. In the second cohort of older neonates, we compared paired LVO measurements by echo and magnetic resonance imaging (MRI).

RESULTS

In the first cohort of 48 neonates, mean (standard deviation) weight and age at scan were 1046 (302) g and 28.1 (2.7) weeks. Interobserver bias (95% limits of agreement [LOA]) for LVOTD at the AV, AS, and STJ was 0 (-0.3 to 0.3) mm, 0 (-0.7 to 0.7) mm, and 0 (-0.8 to 0.7) mm, respectively. Interobserver bias (95% LOA) for the corresponding LVO was -1.3 (-31 to 33) ml/kg/min, -0.5 (-88 to 87) ml/kg/min, and -7.2 (-83 to 69) ml/kg/min, respectively. In the second cohort of 10 neonates, median (range) weight and age at scan were 1942 (970-3640) g and 37.2 (31.7-39.8) weeks. LVO measured at the AV showed stronger agreement with MRI: bias (LOA) -10.6 (-74 to 52) ml/kg/min, compared to LVO measured at AS and STJ: 194 (-0.5 to 388) ml/kg/min and 43 (-72 to 159) ml/kg/min respectively.

CONCLUSIONS

Reproducibility and accuracy of LVO quantification by echo were better when aortic diameter was measured at AV.

The care of critically ill infants and toddlers in neonatal intensive care units across Italy and Europe: our proposal for healthcare organization

Numerous studies have shown that critically ill infants and toddlers admitted to paediatric intensive care units (PICUs) have a lower mortality than those admitted to adult ICUs. In 2014, there were only 23 registered PICUs in Italy, most of which were located in the north. For this reason, in Italy and elsewhere in Europe, some neonatal ICUs (NICUs) have begun managing critically ill infants and toddlers. Our proposal for healthcare organization is to establish "extended NICUs" in areas where paediatric intensive care beds are lacking. While some countries have opted for a strict division between neonatal and paediatric intensive care units, the model of "extended NICUs" has already been set up in Italy and in Europe. In this instance, the management of critically ill infants and toddlers undoubtedly falls upon neonatologists, who, however, must gain specific knowledge and technical skills in paediatric critical care medicine (PCCM). Postgraduate residencies in paediatrics need to include periods of specific training in neonatology and PCCM. The Italian Society of Neonatology's Early Childhood Intensive Care Study Group is supporting certified training courses for its members involving both theory and practice.

CONCLUSION

Scientific societies should promote awareness of the issues involved in the intensive management of infants and toddlers in NICUs and the training of all health workers involved. These societies include the Italian Society of Neonatology, the European Society of Paediatric and Neonatal Intensive Care, and the Union of European Neonatal and Perinatal Societies. They should also act in concert with the governmental institutional bodies to establish the standards for the "extended NICUs."

WHAT IS KNOWN

• The mortality of critically ill infants and toddlers admitted to PICUs is lower than that for those admitted to adult ICUs. • In Italy, there are only a handful of PICUs, located mainly in the north.

WHAT IS NEW

• Critically ill infants and small toddlers can be managed in "extended NICUs" in areas with a lack of paediatric intensive care beds. • "Extended NICUs" is our proposal for healthcare organization to compensate for the paucity of paediatric intensive care beds, but neonatologists must be trained to provide them with specific knowledge and technical skills in PCCM.

Criteria for Pediatric Sepsis-A Systematic Review and Meta-Analysis by the Pediatric Sepsis Definition Taskforce

OBJECTIVE

To determine the associations of demographic, clinical, laboratory, organ dysfunction, and illness severity variable values with: 1) sepsis, severe sepsis, or septic shock in children with infection and 2) multiple organ dysfunction or death in children with sepsis, severe sepsis, or septic shock.

DATA SOURCES

MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from January 1, 2004, and November 16, 2020.

STUDY SELECTION

Case-control studies, cohort studies, and randomized controlled trials in children greater than or equal to 37-week-old postconception to 18 years with suspected or confirmed infection, which included the terms "sepsis," "septicemia," or "septic shock" in the title or abstract.

DATA EXTRACTION

Study characteristics, patient demographics, clinical signs or interventions, laboratory values, organ dysfunction measures, and illness severity scores were extracted from eligible articles. Random-effects meta-analysis was performed.

DATA SYNTHESIS

One hundred and six studies met eligibility criteria of which 81 were included in the meta-analysis. Sixteen studies (9,629 patients) provided data for the sepsis, severe sepsis, or septic shock outcome and 71 studies (154,674 patients) for the mortality outcome. In children with infection, decreased level of consciousness and higher Pediatric Risk of Mortality scores were associated with sepsis/severe sepsis. In children with sepsis/severe sepsis/septic shock, chronic conditions, oncologic diagnosis, use of vasoactive/inotropic agents, mechanical ventilation, serum lactate, platelet count, fibrinogen, procalcitonin, multi-organ dysfunction syndrome, Pediatric Logistic Organ Dysfunction score, Pediatric Index of Mortality-3, and Pediatric Risk of Mortality score each demonstrated significant and consistent associations with mortality. Pooled mortality rates varied among high-, upper middle-, and lower middle-income countries for patients with sepsis, severe sepsis, and septic shock (p < 0.0001).

CONCLUSIONS

Strong associations of several markers of organ dysfunction with the outcomes of interest among infected and septic children support their inclusion in the data validation phase of the Pediatric Sepsis Definition Taskforce.

Fathers' experiences of supporting their partners during their preterm infant's stay in the neonatal intensive care unit: a multi-method study

OBJECTIVE

To explore how the fathers experience their role as a support for their partner and the relationship with them during their preterm infant's stay in the NICU.

STUDY DESIGN

Multi-method longitudinal study involving ethnographic observation, semi-structured interviews, self-report questionnaires, and clinical information. Twenty fathers of preterm infants hospitalized in a level-III-NICU were included. Data were analyzed using thematic continent analysis.

RESULTS

Three main themes were identified: support for mother (subthemes: putting mother's and infant's needs first; hiding worries and negative emotions; counteracting the sense of guilt; fear that the mother would reject the child), mother's care for the infant (subthemes: observing mother engaged in caregiving; mother has "something extra"), and couple relationship (subthemes: collaboration; bond).

CONCLUSION

Fathers supporting their partners during the stay in the NICU experience emotional distress and the need for being supported that often are hidden. This demands a great deal of emotional and physical energy.

Thermal management with and without servo-controlled system in preterm infants immediately after birth: a multicentre, randomised controlled study

BACKGROUND

The thermal servo-controlled systems are routinely used in neonatal intensive care units (NICUs) to accurately manage patient temperature, but their role during the immediate postnatal phase has not been previously assessed.

OBJECTIVE

To compare two modalities of thermal management (with and without the use of a servo-controlled system) immediately after birth.

STUDY DESIGN AND SETTING

Multicentre, unblinded, randomised trial conducted 15 Italian tertiary hospitals.

PARTICIPANTS

Infants with estimated birth weight <1500 g and/or gestational age <30⁺⁶ weeks.

INTERVENTION

Thermal management with or without a thermal servo-controlled system during stabilisation in the delivery room.

PRIMARY OUTCOME

Proportion of normothermia at NICU admission (axillary temperature 36.5°C-37.5°C).

RESULTS

At NICU admission, normothermia was achieved in 89/225 neonates (39.6%) with the thermal servo-controlled system and 95/225 neonates (42.2%) without the thermal servo-controlled system (risk ratio 0.94, 95% CI 0.75 to 1.17). Thermal servo-controlled system was associated with increased mild hypothermia (36°C-36.4°C) (risk ratio 1.48, 95% CI 1.09 to 2.01).

CONCLUSIONS

In very low birthweight infants, thermal management with the servo-controlled system conferred no advantage in maintaining normothermia at NICU admission, while it was associated with increased mild hypothermia. Thermal management of preterm infants immediately after birth remains a challenge.

TRIAL REGISTRATION NUMBER

Life-sustaining treatment decisions in pediatric intensive care: an Italian survey on ethical concerns

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.

Could myocardial function be predictive of successful extubation in newborns and infants?

OBJECTIVE

To investigate the relationship between cardiac function and extubation readiness in infants using speckle tracking echocardiography.

WORKING HYPOTHESIS

Cardiac function combined with established clinical parameters may better identify readiness for extubation.

STUDY DESIGN

Pilot prospective observational study.

PATIENT SELECTION

Mechanically ventilated infants were included.

METHODOLOGY

Cardiac function was assessed by echocardiography immediately before extubation. Systolic and diastolic function in the left (LV) and right ventricles (RV) were assessed by measurement of longitudinal strain (LS), and circumferential strain (CS) in the LV only. Pulmonary artery pressures were assessed using the velocity of tricuspid regurgitation jet (TR), septal position, and end-systolic eccentricity index (EI ES). Cases who extubated successfully (Group 1) were compared to cases who required reintubation (Group 2).

RESULTS

Twenty-five cases were included. LV CS and RV LS were significantly lower in those who required reintubation (Group 2) compared to those who were successfully extubated (Group 1) (LV CS, -21 (12)% vs. -33 (3)%, p = .001; RV LS -19 (2.7)% vs. -20 (2.5)%, p = .04). TR was absent in all cases. The septal shape was normal in 18 cases (72%), displaced to the left in 7 (28%) cases. No significant differences were found in LV EI ES between groups.

The Ex utero intrapartum treatment (EXIT) procedure: case report of a multidisciplinary team approach

BACKGROUND AND AIM OF THE WORK

The EXIT-to-airway procedure is aimed to provide the time required to secure airways when an extrinsic or intrinsic fetal mass raise concerns about airways control at delivery. Due to the rarity of the procedure, we aim to provide a summary of the appropriate prenatal planning by a multidisciplinary team.

METHODS

Report of a case of EXIT-to-airway procedure.

RESULTS

A 30 years-old woman, G2P1 with previous cesarean section, was referred to our Unit at 34 gestational weeks due to a fetal cervical mass of 7cm. An EXIT-to-airways procedure was performed by a multidisciplinary team after accurate preoperative planning and the practice simulations. The partial fetal extraction and the amnioinfusion of pre-heated saline were used to prevent fetal complications. The use of supplemental intravenous anesthesia with remifentanil and better control of uterine tone with nitroglycerin allowed to reduce the exposure to volatile halogen for both the mother and the fetus. The accurate preoperative planning and the practice simulations allowed us to perform the treatment safely in urgency due to the onset of spontaneous labor at 37 weeks and 6 days.

CONCLUSIONS

The strong cooperation among specialists, accurate prenatal planning, and adopting all the required procedures and precautions are of paramount importance to successfully perform the EXIT-to-airway procedure.

Neonatal and Pediatric Emergency Room Visits in a Tertiary Center during the COVID-19 Pandemic in Italy

The COVID-19 pandemic is affecting healthcare services worldwide. We investigated the impact of a strict lockdown policy on the characteristics of neonatal and pediatric attendances to our pediatric emergency department (PED). The clinical features of PED visits in March-April 2020 (COVID-19) and March-April 2019 (non-COVID-19) were analyzed. During the COVID-19 lockdown period, visits reduced by 67%, from 3159 to 1039. Neonatal access decreased from 78 to 59, mainly due to fewer pathological conditions, with a complete disappearance of respiratory infections. On the other hand, minor neonatal clinical conditions rose from 44 (56.4%) to 48 (81.4%), mostly due to feeding-related issues. Communicable diseases, particularly respiratory infections and gastroenteritis, dropped from 1552 (49.1%) to 288 (27.7%). Accident-related visits also decreased during COVID-19, from 535 (16.9%) to 309 (29.7%), becoming the most common cause of PED access. Hospital admissions reduced from 266 to 109, while PICU (pediatric intensive care unit) admissions decreased from 27 to 11, with a comparable rate of 10.1% in both periods. The lockdown due to COVID-19 had a substantial impact on our PED visits, which markedly decreased, mainly due to fewer respiratory infections. Unexpectedly, neonatal visits for minor conditions did not decline, but rather slightly increased. Among the children admitted to the PICU, none had respiratory disease.

Characteristics and risk factors for SARS-CoV-2 in children tested in the early phase of the pandemic: a cross-sectional study, Italy, 23 February to 24 May 2020

BackgroundVery few studies describe factors associated with COVID-19 diagnosis in children.AimWe here describe characteristics and risk factors for COVID-19 diagnosis in children tested in 20 paediatric centres across Italy.MethodsWe included cases aged 0-18 years tested between 23 February and 24 May 2020. Our primary analysis focused on children tested because of symptoms/signs suggestive of COVID-19.ResultsAmong 2,494 children tested, 2,148 (86.1%) had symptoms suggestive of COVID-19. Clinical presentation of confirmed COVID-19 cases included besides fever (82.4%) and respiratory signs or symptoms (60.4%) also gastrointestinal (18.2%), neurological (18.9%), cutaneous (3.8%) and other unspecific influenza-like presentations (17.8%). In multivariate analysis, factors significantly associated with SARS-CoV-2 positivity were: exposure history (adjusted odds ratio (AOR): 39.83; 95% confidence interval (CI): 17.52-90.55; p < 0.0001), cardiac disease (AOR: 3.10; 95% CI: 1.19-5.02; p < 0.0001), fever (AOR: 3.05%; 95% CI: 1.67-5.58; p = 0.0003) and anosmia/ageusia (AOR: 4.08; 95% CI: 1.69-9.84; p = 0.002). Among 190 (7.6%) children positive for SARS-CoV-2, only four (2.1%) required respiratory support and two (1.1%) were admitted to intensive care; all recovered.ConclusionRecommendations for SARS-CoV-2 testing in children should consider the evidence of broader clinical features. Exposure history, fever and anosmia/ageusia are strong risk factors in children for positive SARS-CoV-2 testing, while other symptoms did not help discriminate positive from negative individuals. This study confirms that COVID-19 was a mild disease in the general paediatric population in Italy. Further studies are needed to understand risk, clinical spectrum and outcomes of COVID-19 in children with pre-existing conditions.

The Collateral Impact of COVID-19 Emergency on Neonatal Intensive Care Units and Family-Centered Care: Challenges and Opportunities

The ongoing Coronavirus disease 2019 (COVID-19) pandemic is disrupting most specialized healthcare services worldwide, including those for high-risk newborns and their families. Due to the risk of contagion, critically ill infants, relatives and professionals attending neonatal intensive care units (NICUs) are undergoing a profound remodeling of the organization and quality of care. In particular, mitigation strategies adopted to combat the COVID-19 pandemic may hinder the implementation of family-centered care within the NICU. This may put newborns at risk for several adverse effects, e.g., less weight gain, more nosocomial infections, increased length of NICU stay as well as long-term worse cognitive, emotional, and social development. This article aims to contribute to deepening the knowledge on the psychological impact of COVID-19 on parents and NICU staff members based on empirical data from the literature. We also provided evidence-based indications on how to safely empower families and support NICU staff facing such a threatening emergency, while preserving the crucial role of family-centered developmental care practices.

Surfactant therapies for pediatric and neonatal ARDS: ESPNIC expert consensus opinion for future research steps

Pediatric (PARDS) and neonatal (NARDS) acute respiratory distress syndrome have different age-specific characteristics and definitions. Trials on surfactant for ARDS in children and neonates have been performed well before the PARDS and NARDS definitions and yielded conflicting results. This is mainly due to heterogeneity in study design reflecting historic lack of pathobiology knowledge. We reviewed the available clinical and preclinical data to create an expert consensus aiming to inform future research steps and advance the knowledge in this area. Eight trials investigated the use of surfactant for ARDS in children and ten in neonates, respectively. There were improvements in oxygenation (7/8 trials in children, 7/10 in neonates) and mortality (3/8 trials in children, 1/10 in neonates) improved. Trials were heterogeneous for patients' characteristics, surfactant type and administration strategy. Key pathobiological concepts were missed in study design. Consensus with strong agreement was reached on four statements: 1. There are sufficient preclinical and clinical data to support targeted research on surfactant therapies for PARDS and NARDS. Studies should be performed according to the currently available definitions and considering recent pathobiology knowledge. 2. PARDS and NARDS should be considered as syndromes and should be pre-clinically studied according to key characteristics, such as direct or indirect (primary or secondary) nature, clinical severity, infectious or non-infectious origin or patients' age. 3. Explanatory should be preferred over pragmatic design for future trials on PARDS and NARDS. 4. Different clinical outcomes need to be chosen for PARDS and NARDS, according to the trial phase and design, trigger type, severity class and/or surfactant treatment policy. We advocate for further well-designed preclinical and clinical studies to investigate the use of surfactant for PARDS and NARDS following these principles.

Cell Population Data (CPD) for Early Recognition of Sepsis and Septic Shock in Children: A Pilot Study

Objectives: Innovative Cell Population Data (CPD) have been used as early biomarkers for diagnosing sepsis in adults. We assessed the usefulness of CPD in pediatric patients with sepsis/septic shock, in terms of early recognition and outcome prediction. We revised 54 patients (0-15 y) admitted to our Pediatric Intensive Care Unit (PICU) for sepsis/septic shock during a 4-year period. Twenty-eight patients were excluded, 26 septic patients were enrolled (G1). Forty children admitted for elective surgery served as controls (G2). Data on five selected CPD parameters, namely neutrophils fluorescence intensity (NE-SFL), monocytes cells complexity (MO-X), monocytes fluorescence intensity (MO-Y), monocytes complexity and width of dispersion of events measured (MO-WX), and monocytes cells size and width dispersion (MO-WZ), were obtained at time of PICU admission (t0) by a hematological analyzer (Sysmex XN 9000®). As the primary outcome we evaluated the relevance of CPD for diagnosing sepsis/septic shock on PICU admission. Furthermore, we investigated if CPD at t0 were correlated with C-reactive protein (CRP), patient survival, or complicated sepsis course. Results: On PICU admission (t0), NE-SFL, MO-WX, and MO-Y were higher in sepsis/septic shock patients compared to controls. NE-SFL values were correlated with CRP values in G1 patients (r = 0.83). None of the five CPD parameters was correlated with survival or complicated sepsis course. Conclusion: We found higher values of NE-SFL, MO-WX, and MO-Y in children with sepsis/septic shock upon PICU admission. These parameters may be a promising adjunct for early sepsis diagnosis in pediatric populations. Larger, prospective studies are needed to confirm our preliminary observations.

Accuracy of Point-of-Care Ultrasound in Detecting Fractures in Children: A Validation Study

This study sought to compare point-of-care ultrasound (POCUS) and conventional X-rays for detecting fractures in children. This was a prospective, non-randomized, convenience-sample study conducted in five medical centers. It evaluated pediatric patients with trauma. POCUS and X-ray examination results were treated as dichotomous variables with fracture either present or absent. Descriptive statistics were calculated in addition to prevalence, sensitivity, specificity, positive predictive value and negative predictive value, including 95% confidence intervals (CIs). The Cohen κ coefficient was determined as a measurement of the level of agreement. A total of 554 examinations were performed with POCUS and X-ray. On physical examination, swelling, localized hematoma and functional limitation were found in 66.73%, 33.78% and 53.74% of participants, respectively. The most-studied areas were limbs and hands/feet (58.19% and 38.27%), whereas the thorax was less represented (3.54%). Sensitivity of POCUS was 91.67% (95% CI, 76.41-97.82%) for high-skill providers and 71.50 % (95% CI, 64.75-77.43%) for standard-skill providers. Specificity was 88.89% (95% CI, 73.00-96.34%) and 82.91% (95% CI, 77.82-87.06%) for high- and standard-skill providers, respectively. Positive predictive value was 89.19% (95% CI, 73.64-96.48%) and 75.90% (95% CI, 69.16-81.59%) for high- and standard-skill providers, respectively. Negative predictive value was 91.43% (95% CI, 75.81-97.76%) and 79.44% (95% CI, 74.21-83.87%) for high- and standard-skill providers, respectively. The Cohen κ coefficient showed very good agreement (0.81) for high-skill providers, but moderate agreement (0.54) for standard-skill providers. We noted good diagnostic accuracy of POCUS in evaluating fracture, with excellent sensitivity, specificity, and positive and negative predictive value for high-skill providers.

Remote Teamwork Management of NORSE During the COVID-19 Lockdown

New-onset refractory status epilepticus (NORSE) is rare condition, and sharing knowledge is vital in its management, based on strict collaboration between multiple specialists, continuous EEG (c-EEG) monitoring, and prompt therapy modification. The coronavirus disease 2019 (COVID-19) pandemic challenged many of these established practices because of "social distancing" measures, making it necessary to work around physical restrictions. We report a case of a 10-year-old with NORSE admitted in a pediatric intensive-care unit and monitored with c-EEG and amplitude-integrated EEG. The monitoring interface was livestreamed using videoconference web-based platforms allowing remote viewing. Multiple daily web meetings took place between team members, where real-time therapy response was evaluated and confronted with medium-term trends in the epileptic activity, dictating further treatment and diagnostic steps. In addition to the known use of telemedicine in chronic conditions, we report how its use can be exploited to treat urgent conditions such as NORSE. By taking advantage of new tools and virtual environments, we were able to share treatment and diagnostic decisions and guarantee real-time therapy adjustments and a coherent course in treatment despite restrictions necessary for the COVID-19 pandemic. The constant specialist monitoring and the coherent and on-time communication of the patient's condition relieved the family stress, usually complained in these situations.

COVID-19 in 17 Italian Pediatric Emergency Departments

BACKGROUND

Variability in presentation of children with coronavirus disease 2019 (COVID-19) is a challenge in emergency departments (EDs) in terms of early recognition, which has an effect on disease control and prevention. We describe a cohort of 170 children with COVID-19 and differences with the published cohorts.

METHODS

Retrospective chart reviews on children (0-18 years) evaluated in 17 Italian pediatric EDs.

RESULTS

In our cohort (median age of 45 months; interquartile range of 4 months-10.7 years), we found a high number of patients <1 year with COVID-19 disease. The exposure happened mainly (59%) outside family clusters; 22% had comorbidities. Children were more frequently asymptomatic (17%) or with mild diseases (63%). Common symptoms were cough (43%) and difficulty feeding (35%). Chest computed tomography, chest radiograph, and point-of-care lung ultrasound were used in 2%, 36%, and 8% of cases, respectively. Forty-three percent of patients were admitted because of their clinical conditions. The minimal use of computed tomography and chest radiograph may have led to a reduced identification of moderate cases, which may have been clinically classified as mild cases.

CONCLUSIONS

Italian children evaluated in the ED infrequently have notable disease symptoms. For pediatrics, COVID-19 may have rare but serious and life-threatening presentations but, in the majority of cases, represents an organizational burden for the ED. These data should not lower the attention to and preparedness for COVID-19 disease because children may represent a source of viral transmission. A clinically driven classification, instead of a radiologic, could be more valuable in predicting patient needs and better allocating resources.

Efficacy and safety of exogenous surfactant therapy in patients under 12 months of age invasively ventilated for severe bronchiolitis (SURFABRON): protocol for a multicentre, randomised, double-blind, controlled, non-profit trial

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.

Characteristic of COVID-19 infection in pediatric patients: early findings from two Italian Pediatric Research Networks

Detailed data on clinical presentations and outcomes of children with COVID-19 in Europe are still lacking. In this descriptive study, we report on 130 children with confirmed COVID-19 diagnosed by 28 centers (mostly hospitals), in 10 regions in Italy, during the first months of the pandemic. Among these, 67 (51.5%) had a relative with COVID-19 while 34 (26.2%) had comorbidities, with the most frequent being respiratory, cardiac, or neuromuscular chronic diseases. Overall, 98 (75.4%) had an asymptomatic or mild disease, 11 (8.5%) had moderate disease, 11 (8.5%) had a severe disease, and 9 (6.9%) had a critical presentation with infants below 6 months having significantly increased risk of critical disease severity (OR 5.6, 95% CI 1.3 to 29.1). Seventy-five (57.7%) children were hospitalized, 15 (11.5%) needed some respiratory support, and nine (6.9%) were treated in an intensive care unit. All recovered.Conclusion:This descriptive case series of children with COVID-19, mostly encompassing of cases enrolled at hospital level, suggest that COVID-19 may have a non-negligible rate of severe presentations in selected pediatric populations with a relatively high rates of comorbidities. More studies are needed to further understand the presentation and outcomes of children with COVID-19 in children with special needs. What is Known: • There is limited evidence on the clinical presentation and outcomes of children with COVID-19 in Europe, and almost no evidence on characteristics and risk factors of severe cases. What is New: • Among a case series of 130 children, mostly diagnosed at hospital level, and with a relatively high rate (26.2%) of comorbidities, about three-quarter had an asymptomatic or mild disease. • However, 57.7% were hospitalized, 11.5% needed some respiratory support, and 6.9% were treated in an intensive care unit.

The quality of life in extracorporeal life support survivors: single-center experience of a long-term follow-up

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.

Multicentre emergency department study found that paracetamol and ibuprofen were inappropriately used in 83% and 63% of paediatric cases

AIM

The Pain Practice in Italian Paediatric Emergency Departments assessed how appropriately analgesic drugs were being used by Italian clinicians, based on national paediatric pain guidelines.

METHODS

This was a retrospective study that involved 17 Italian members of the Pain In Pediatric Emergency Rooms group. It comprised patients up to the age of 14 years who came to hospital emergency departments with pain and were treated with paracetamol, ibuprofen or opioids, such as codeine, tramadol and morphine.

RESULTS

We studied 1471 patients who were given 1593 doses of analgesics. The median time to administration of analgesia was 25 minutes. Opioids were used in 13.5% of the children, and usage increased with age and with more severe clinical conditions, such as trauma: 1.6% of children under two years, 5.9% aged 3-10 and 8.0% aged 11-14. Inappropriate doses of paracetamol, ibuprofen and opioids were used in 83%, 63% and 33% of cases, respectively. The patient's age was a critical determinant of the correct analgesic dosage; for every one-year increase in the patient's age, the probability of appropriate prescriptions rose 14.8%.

CONCLUSION

The appropriate use of paracetamol and ibuprofen for paediatric pain in Italian emergency departments was very poor, but improved with age.

Clinical pitfalls in the diagnosis of segmental overgrowth syndromes: a child with the c.2740G > A mutation in PIK3CA gene

BACKGROUND

Overgrowth syndromes are known as a heterogeneous group of conditions characterized by a generalized or segmental, symmetric or asymmetric, overgrowth that may involve several tissues. These disorders, which present a wide range of phenotypic variability, are often caused by mosaic somatic mutations in the genes associated with the PI3K/AKT/mTOR cellular pathway, a signaling cascade that plays a key role in cellular growth. Overgrowth syndromes are frequently misdiagnosed. Given that they are also associated to an increased oncologic risk, it is important to distinguish the clinical characteristic of these disorders since the first months of life.

CASE PRESENTATION

We report the case of a seven-year-old male child with macrocephaly and right lateralized overgrowth, reported from birth. The patient arrived to our attention after an initial diagnosis of isolated benign macrocephaly was formulated at the age of 12 months. Afterwards, the child presented a moderate intellectual disability and pain episodes at right lower limb. We repeated a brain Magnetic Resonance Imaging that revealed ventriculomegaly, cerebellar tonsillar ectopia, a markedly thick corpus callosum, and white matter abnormalities. The diagnosis of segmental overgrowth syndrome was formulated according to the clinical presentation and confirmed by the finding of the variant c.2740G > A in the gene PIK3CA presented in somatic mosaicism.

CONCLUSIONS

Our patient is the first children with the c.2740G > A variant in PIK3CA gene reported in Italy. We underline the importance of the genotype-phenotype correlation in the diagnostic process of overgrowth syndromes and emphasize the strict correlation between the mutation c.2740G > A in the PIK3CA gene and the Megalencephaly-Capillary Malformation syndrome phenotype.

Fathers' experiences with their preterm babies admitted to neonatal intensive care unit: A multi-method study

AIM

The aim of this study was to investigate fathers' emotional experiences of their infant's preterm birth and subsequent stay in neonatal intensive care unit.

BACKGROUND

When a baby is born preterm, there is also the premature interruption of the process of preparation for fatherhood. As a result, the impact on fathers of the preterm birth can bring negative consequences for the development of father-infant relationship.

DESIGN

A multi-method approach was used which included ethnographic observation, semi-structured interviews with fathers, a self-report questionnaire and clinical information between September 2015-March 2017.

METHOD

Data were analysed using a mixed-method: a thematic analysis of data from the interviews and quantitative analyses to detect possible clusters of fathers' emotional experiences and associations between clusters and fathers' and/or infants' characteristics.

RESULTS

Two clusters were identified. The "fathers-of-preterm-infants" touched their baby as soon as they were given the opportunity and without fear that they would harm their infant. They were struck by their baby's physical appearance. In contrast, the "preterm fathers" preferred not to touch their baby when first given the chance, for fear of breaking/damaging/infecting her/him. They were struck both by the baby's physical appearance and by the technology/equipment around her/him and were afraid that their infant would die. All the "fathers-of-preterm-infants", but only just over half of the "preterm fathers", were actively engaged in their infant's care. Clusters were associated with the infant's gestational age.

CONCLUSION

Fathers of preterm infants should receive personalized support specifically addressed to them and based on the infant's gestational age.

Symptomatic congenital Cytomegalovirus deafness: the impact of a six-week course of antiviral treatment on hearing improvement

Congenital Cytomegalovirus infection is the leading non-genetic cause of neurosensory deafness. We compared the outcomes of a treated group of children to an untreated group. The effect of antiviral therapy on hearing improvement between baseline and 2-year follow-up was statistically significant. These results suggest that the benefit of 6-week therapy is not limited to preventing further hearing deterioration.

Oral Ondansetron versus Domperidone for Acute Gastroenteritis in Pediatric Emergency Departments: Multicenter Double Blind Randomized Controlled Trial

The use of antiemetics for vomiting in acute gastroenteritis in children is still a matter of debate. We conducted a double-blind randomized trial to evaluate whether a single oral dose of ondansetron vs domperidone or placebo improves outcomes in children with gastroenteritis. After failure of initial oral rehydration administration, children aged 1–6 years admitted for gastroenteritis to the pediatric emergency departments of 15 hospitals in Italy were randomized to receive one oral dose of ondansetron (0.15 mg/kg) or domperidone (0.5 mg/kg) or placebo. The primary outcome was the percentage of children receiving nasogastric or intravenous rehydration. A p value of 0.014 was used to indicate statistical significance (and 98.6% CI were calculated) as a result of having carried out two interim analyses. 1,313 children were eligible for the first attempt with oral rehydration solution, which was successful for 832 (63.4%); 356 underwent randomization (the parents of 125 children did not give consent): 118 to placebo, 119 to domperidone, and 119 to ondansetron. Fourteen (11.8%) needed intravenous rehydration in the ondansetron group vs 30 (25.2%) and 34 (28.8%) in the domperidone and placebo groups, respectively. Ondansetron reduced the risk of intravenous rehydration by over 50%, both vs placebo (RR 0.41, 98.6% CI 0.20–0.83) and domperidone (RR 0.47, 98.6% CI 0.23–0.97). No differences for adverse events were seen among groups. In a context of emergency care, 6 out of 10 children aged 1–6 years with vomiting due to gastroenteritis and without severe dehydration can be managed effectively with administration of oral rehydration solution alone. In children who fail oral rehydration, a single oral dose of ondansetron reduces the need for intravenous rehydration and the percentage of children who continue to vomit, thereby facilitating the success of oral rehydration. Domperidone was not effective for the symptomatic treatment of vomiting during acute gastroenteritis.

Efficacy of ketamine in refractory convulsive status epilepticus in children: a protocol for a sequential design, multicentre, randomised, controlled, open-label, non-profit trial (KETASER01)

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.

Nationwide study of headache pain in Italy shows that pain assessment is still inadequate in paediatric emergency care

Aim

Italian national guidelines on pain management were published in 2010, but there is little information on how effective pain management is in paediatric emergency care, with other countries reporting poor levels. Using headache as an indicator, we described pain assessment in Italian emergency departments and identified predictors of algometric scale use.

Methods

All Italian paediatric and maternal and child hospitals participated, plus four general hospitals. Data on all children aged 4–14 years admitted during a one‐month period with headache as their chief complaint were abstracted from clinical records. Multivariable analyses identified predictors of algometric assessment, taking into account the cluster study design.

Results

We studied 470 admissions. During triage, pain was assessed using a standardised scale (41.5%), informally (15.5%) or was not recorded (42.9%). Only 32.1% of the children received analgesia in the emergency department. The odds ratios for predictors of algometric assessment were non‐Italian nationality (3.6), prehospital medication (1.8), admission to a research hospital (7.3) and a more favourable nurses‐to‐admissions ratio of 10.8 for the highest versus lowest tertile.

Conclusion

Despite national guidelines, paediatric pain assessment in Italian emergency care was suboptimal. Hospital variables appeared to be stronger predictors of adequate assessment than patient characteristics.

Diagnosis and management of acute mastoiditis in a cohort of Italian children

OBJECTIVE

The Italian Society for Pediatric Infectious Diseases created a registry to determine the management of pediatric acute mastoiditis (AM) in Italy.

METHODS

A cross-sectional survey of paediatricians was conducted to evaluate hospitalization due to AM in Italian pediatric wards between 1 January 2002, and 31 December 2013.

RESULTS

A total of 913 children (561 males, 61.4%) were included in this study. The annual number of AM cases significantly increased during the study period (30 in 2002 and 98 in 2013) but only among older children (≥ 4 years old; p = 0.02). AM complications occurred in 69 (7.6%) of the children and sequelae were observed in 13 (1.4%) patients.

CONCLUSION

The annual number of pediatric AM cases admitted to Italian pediatric wards increased in the past few years; this increase was strictly age-related. The risk of severe AM complications appeared relatively low, and most AM cases could be treated conservatively.

Sustained lung inflation at birth for preterm infants: a randomized clinical trial

BACKGROUND

Studies suggest that giving newly born preterm infants sustained lung inflation (SLI) may decrease their need for mechanical ventilation (MV) and improve their respiratory outcomes.

METHODS

We randomly assigned infants born at 25 weeks 0 days to 28 weeks 6 days of gestation to receive SLI (25 cm H2O for 15 seconds) followed by nasal continuous positive airway pressure (nCPAP) or nCPAP alone in the delivery room. SLI and nCPAP were delivered by using a neonatal mask and a T-piece ventilator. The primary end point was the need for MV in the first 72 hours of life. The secondary end points included the need for respiratory supports and survival without bronchopulmonary dysplasia (BPD).

RESULTS

A total of 148 infants were enrolled in the SLI group and 143 in the control group. Significantly fewer infants were ventilated in the first 72 hours of life in the SLI group (79 of 148 [53%]) than in the control group (93 of 143 [65%]); unadjusted odds ratio: 0.62 [95% confidence interval: 0.38-0.99]; P = .04). The need for respiratory support and survival without BPD did not differ between the groups. Pneumothorax occurred in 1% (n = 2) of infants in the control group compared with 6% (n = 9) in the SLI group, with an unadjusted odds ratio of 4.57 (95% confidence interval: 0.97-21.50; P = .06).

CONCLUSIONS

SLI followed by nCPAP in the delivery room decreased the need for MV in the first 72 hours of life in preterm infants at high risk of respiratory distress syndrome compared with nCPAP alone but did not decrease the need for respiratory support and the occurrence of BPD.

Diagnostic pitfalls in the assessment of congenital hypopituitarism

BACKGROUND

The diagnosis of congenital hypopituitarism is difficult and often delayed because its symptoms are nonspecific.

AIM

To describe the different clinical presentations of children with congenital hypopituitarism to reduce the time for diagnosis and to begin a precocious and appropriate treatment.

STUDY DESIGN

We analyzed a cohort of five children with congenital hypopituitarism, describing their clinical, biochemical and radiological characteristics from the birth to diagnosis.

RESULTS

As first sign of the disease, all of five patients presented a neonatal hypoglycemia, associated in four cases with jaundice. In all these four cases, the clinicians hypothesized a metabolic disease delaying the diagnosis, which was performed in only two cases within the neonatal period. In the other three cases, the diagnosis was formulated at 2, 5 and 8 years of life because there was severe and precocious growth impairment.

CONCLUSIONS

It is important to suspect congenital hypopituitarism in the presence of persistent neonatal hypoglycemia associated with jaundice and of a precocious and severe reduction of the growth velocity in childhood. In all these cases, it is necessary to undertake a hypothalamic-pituitary magnetic resonance imaging scan as soon as possible, and to start appropriate treatment.

Inter-society consensus document on treatment and prevention of bronchiolitis in newborns and infants

Acute bronchiolitis is the leading cause of lower respiratory tract infection and hospitalization in children less than 1 year of age worldwide. It is usually a mild disease, but some children may develop severe symptoms, requiring hospital admission and ventilatory support in the ICU. Infants with pre-existing risk factors (prematurity, bronchopulmonary dysplasia, congenital heart diseases and immunodeficiency) may be predisposed to a severe form of the disease.

Clinical diagnosis of bronchiolitis is manly based on medical history and physical examination (rhinorrhea, cough, crackles, wheezing and signs of respiratory distress). Etiological diagnosis, with antigen or genome detection to identify viruses involved, may have a role in reducing hospital transmission of the infection.

Criteria for hospitalization include low oxygen saturation (<90-92%), moderate-to-severe respiratory distress, dehydration and presence of apnea. Children with pre-existing risk factors should be carefully assessed.

To date, there is no specific treatment for viral bronchiolitis, and the mainstay of therapy is supportive care. This consists of nasal suctioning and nebulized 3% hypertonic saline, assisted feeding and hydration, humidified O₂ delivery. The possible role of any pharmacological approach is still debated, and till now there is no evidence to support the use of bronchodilators, corticosteroids, chest physiotherapy, antibiotics or antivirals. Nebulized adrenaline may be sometimes useful in the emergency room. Nebulized adrenaline can be useful in the hospital setting for treatment as needed. Lacking a specific etiological treatment, prophylaxis and prevention, especially in children at high risk of severe infection, have a fundamental role. Environmental preventive measures minimize viral transmission in hospital, in the outpatient setting and at home. Pharmacological prophylaxis with palivizumab for RSV bronchiolitis is indicated in specific categories of children at risk during the epidemic period.

Viral bronchiolitis, especially in the case of severe form, may correlate with an increased incidence of recurrent wheezing in pre-schooled children and with asthma at school age.

The aim of this document is to provide a multidisciplinary update on the current recommendations for the management and prevention of bronchiolitis, in order to share useful indications, identify gaps in knowledge and drive future research.

Acute onset of bilateral visual loss during sildenafil therapy in a young infant with congenital heart disease

We report a case of posterior non-arteritic ischaemic optic neuropathy (NAION) causing bilateral visual loss in a 7-month-old female infant, after a therapeutic course with sildenafil, a phosphodiesterase type 5 inhibitors (PDE5i). The patient was affected by a complex cyanotic congenital heart defect and had undergone cavopulmonary anastomosis (Glenn operation) 3 months ago. After 2 months of recurring chylothorax, a course of oral sildenafil was administered, with the hypothesis that pulmonary vascular resistances were increased. Approximately 4 weeks later the acute onset of visual worsening and poor pupillary light reflex prompted the diagnosis of posterior NAION. Despite a rapid cessation of PDE5i and systemic treatment with corticosteroids, no visual recovery was noticed at 2-year follow-up. NAION has been associated with PDE5i therapy in adults, but to the best of our knowledge it is almost unheard of in children. We suggest close monitoring of visual function in children undergoing treatment with sildenafil.

Ultrastructural characterization of genetic diffuse lung diseases in infants and children: a cohort study and review

Pediatric diffuse lung diseases are rare disorders with an onset in the neonatal period or in infancy, characterized by chronic respiratory symptoms and diffuse interstitial changes on imaging studies. Genetic disorders of surfactant homeostasis represent the main etiology. Surfactant protein B and ABCA3 deficiencies typically cause neonatal respiratory failure, which is often lethal within a few weeks or months. Although heterozygous ABCA3 mutation carriers are mostly asymptomatic, there is growing evidence that monoallelic mutations may affect surfactant homeostasis. Surfactant protein C mutations are dominant or sporadic disorders leading to a broad spectrum of manifestations from neonatal respiratory distress syndrome to adult pulmonary fibrosis. The authors performed pathology and ultrastructural studies in 12 infants who underwent clinical lung biopsy. One carried a heterozygous SP-B mutation, 3 carried SP-C mutations, and 7 carried ABCA3 mutations (5 biallelic and 2 monoallelic). Optical microscopy made it possible to distinguish between surfactant-related disorders and other forms. One of the ABCA3 monoallelic carriers had morphological features of alveolar capillary dysplasia, a genetic disorder of lung alveolar, and vascular development. One patient showed no surfactant-related anomalies but had pulmonary interstitial glycogenosis, a developmental disorder of unknown origin. Electron microscopy revealed specific lamellar bodies anomalies in all SP-B, SP-C, and ABCA3 deficiency cases. In addition, the authors showed that heterozygous ABCA3 mutation carriers have an intermediate ultrastructural phenotype between homozygous carriers and normal subjects. Lung biopsy is an essential diagnostic procedure in unexplained diffuse lung disorders, and electron microscopy should be performed systematically, since it may reveal specific alterations in genetic disorders of surfactant homeostasis.

Coma blisters in children: case report and review of the literature

Coma-induced blisters is a rare condition associated with prolonged impairment of conscious level, which is relatively well-known in adults following overdose with barbiturates. However, it has been very rarely described in children. A case of coma-bullae occurring in an 11-year-old child with meningoencephalitis is herein reported. The bullous lesions occurred on the limbs and trunks, and evolved into necrotic ulcers in a few days. No correlation with any drug overdosage was found. A skin biopsy revealed epidermal and eccrine sweat gland necrosis with abundant neutrophils, and thrombosis of the vessels in the lower dermis. A comprehensive review of the literature showed that only 5 cases of coma-bullae in children have been published so far. Coma blistering resolves spontaneously within days or weeks. Diagnosis of coma-bullae may require careful clinical-pathologic correlation to exclude other blistering diseases in children.

Lactobacillus paracasei subsp. paracasei F19 in Bell's stage 2 of necrotizing enterocolitis

AIM

The aim of this trial is to evaluate the role Lactobacillus paracasei in Bell's stage 2 in order to prevent the clinical progression to stage 3.

METHODS

A prospective study was approved and started in December 2008. Patients were infants with birth weight 600 to 1500 g. One group received probiotic supplementation (L. paracasei susp.paracasei F-19) and the control group received only standard medical treatment. The primary outcome was the progression to stage 3 as defined by Bell's modified criteria. Inclusion and exclusion criteria were created and discussed with parents before treatment.

RESULTS

Thirty-two patients (stage 2 NEC) were considered eligible for the study. Group A: 18 patients and Group B: 14 patients. Three patients in group A and six patients in group B had a clinical history of Bell's stage 3 NEC (P<0.05); oral supplementation of L. paracasei reduced the clinical progression of NEC. It was considered that an improvement in intestinal motility might have contributed to this result.

CONCLUSION

The use of Lactobacillus paracasei subsp. paracasei F-19 is safe; the low progression rate to stage 3 NEC suggests that the use of this probiotic in stage 2 NEC could be a valuable therapeutic option.

Sustained lung inflation in the delivery room in preterm infants at high risk of respiratory distress syndrome (SLI STUDY): study protocol for a randomized controlled trial

Background

Some studies have suggested that the early sustained lung inflation (SLI) procedure is effective in decreasing the need for mechanical ventilation (MV) and improving respiratory outcome in preterm infants. We planned the present randomized controlled trial to confirm or refute these findings.

Methods/Design

In this study, 276 infants born at 25⁺⁰ to 28⁺⁶ weeks’ gestation at high risk of respiratory distress syndrome (RDS) will be randomized to receive the SLI maneuver (25 cmH₂O for 15 seconds) followed by nasal continuous positive airway pressure (NCPAP) or NCPAP alone in the delivery room. SLI and NCPAP will be delivered using a neonatal mask and a T-piece ventilator.

The primary endpoint is the need for MV in the first 72 hours of life. The secondary endpoints include the need and duration of respiratory support (NCPAP, MV and surfactant), and the occurrence of bronchopulmonary dysplasia (BPD).
