BACKGROUND The assessment of real-world effectiveness of immunomodulatory medications for multisystem inflammatory syndrome in children (MIS-C) may guide therapy. METHODS We analyzed surveillance data on inpatients younger than 21 years of age who had MIS-C and were admitted to 1 of 58 US. hospitals between March 15 and October 31, 2020. The effectiveness ofinitial immunomodulatory therapy (day 0, indicating the first day any such therapy for MIS-C was given) with intravenous immune globulin (IVIG) plus glucocorticoids, as compared with IVIG alone, was evaluated with propensity-score matching and inverse probability weighting, with adjustment for baseline MIS-C severity and demographic characteristics. The primary outcome was cardiovascular dysfunction (a composite of left ventricular dysfunction or shock resulting in the use ofvasopressors) on or after day 2. Secondary outcomes included the components of the primary outcome, the receipt of adjunctive treatment (glucocorticoids in patients not already receiving glucocorticoids on day 0, a biologic, or a second dose of IVIG) on or after day 1, and persistent or recurrent fever on or after day 2. RESULTS A total of 518 patients with MIS-C (median age, 8.7 years) received at least one immunomodulatory therapy; 75°6 had been previously healthy, and 9 died. In the propensity-score-matched analysis, initial treatment with IVIG plus glucocorticoids (103 patients) was associated with a lower risk of cardiovascular dysfunction on or after day 2 than IVIG alone (103 patients) (17% vs. 31%; risk ratio, 0.56; 95% confidence interval [CI], 0.34 to 0.94). The risks of the components of the composite outcome were also lower among those who received IVIG plus glucocorticoids: left ventricular dysfunction occurred in 8% and 17% of the patients, respectively (risk ratio, 0.46; 95% CI, 0.19 to 1.15), and shock resulting in vasopressor use in 13% and 24% (risk ratio, 0.54; 95% CI, 0.29 to 1.00). The use of adjunctive therapy was lower among patients who received IVIG plus glucocorticoids than among those who received IVIG alone (34% vs. 70%; risk ratio, 0.49; 95% CI, 0.36 to 0.65), but the risk of fever was unaffected (31% and 40%, respectively; risk ratio, 0.78; 95% CI, 0.53 to 1.13). The inverse-probabilityweighted analysis confirmed the results of the propensity-score-matched analysis. CONCLUSIONS Among children and adolescents with MIS-C, initial treatment with IVIG plus glucocorticoids was associated with a lower risk of new or persistent cardiovascular dysfunction than IVIG alone.

- Abstract
Background: Multisystem inflammatory syndrome in children (MIS-C) is a postinfectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related complication that has disproportionately affected racial/ethnic minority children. We conducted a pilot study to investigate risk factors for MIS-C aiming to understand MIS-C disparities., Methods: This case-control study included MIS-C cases and SARS-CoV-2-positive outpatient controls less than 18 years old frequency-matched 4:1 to cases by age group and site. Patients hospitalized with MIS-C were admitted between March 16 and October 2, 2020, across 17 pediatric hospitals. We evaluated race, ethnicity, social vulnerability index (SVI), insurance status, weight-for-age and underlying medical conditions as risk factors using mixed effects multivariable logistic regression., Results: We compared 241 MIS-C cases with 817 outpatient SARS-CoV-2-positive at-risk controls. Cases and controls had similar sex, age and U.S. census region distribution. MIS-C patients were more frequently previously healthy, non-Hispanic Black, residing in higher SVI areas, and in the 95th percentile or higher for weight-for-age. In the multivariable analysis, the likelihood of MIS-C was higher among non-Hispanic Black children [adjusted odds ratio (aOR): 2.07; 95% CI: 1.23-3.48]. Additionally, SVI in the 2nd and 3rd tertiles (aOR: 1.88; 95% CI: 1.18-2.97 and aOR: 2.03; 95% CI: 1.19-3.47, respectively) were independent factors along with being previously healthy (aOR: 1.64; 95% CI: 1.18-2.28)., Conclusions: In this study, non-Hispanic Black children were more likely to develop MIS-C after adjustment for sociodemographic factors, underlying medical conditions, and weight-for-age. Investigation of the potential contribution of immunologic, environmental, and other factors is warranted., Competing Interests: The authors have no conflicts of interest to disclose.

- Abstract
Background Cardiac complications related to COVID-19 in children and adolescents include ventricular dysfunction, myocarditis, coronary artery aneurysm, and bradyarrhythmias, but tachyarrhythmias are less understood. The goal of this study was to evaluate the frequency, characteristics, and outcomes of children and adolescents experiencing tachyarrhythmias while hospitalized for acute severe COVID-19 or multisystem inflammatory syndrome in children. Methods and Results This study involved a case series of 63 patients with tachyarrhythmias reported in a public health surveillance registry of patients aged <21 years hospitalized from March 15, 2020, to December 31, 2021, at 63 US hospitals. Patients with tachyarrhythmias were compared with patients with severe COVID-19-related complications without tachyarrhythmias. Tachyarrhythmias were reported in 22 of 1257 patients (1.8%) with acute COVID-19 and 41 of 2343 (1.7%) patients with multisystem inflammatory syndrome in children. They included supraventricular tachycardia in 28 (44%), accelerated junctional rhythm in 9 (14%), and ventricular tachycardia in 38 (60%); >1 type was reported in 12 (19%). Registry patients with versus without tachyarrhythmia were older (median age, 15.4 [range, 10.4-17.4] versus 10.0 [range, 5.4-14.8] years) and had higher illness severity on hospital admission. Intervention for treatment of tachyarrhythmia was required in 37 (59%) patients and included antiarrhythmic medication (n=31, 49%), electrical cardioversion (n=11, 17%), cardiopulmonary resuscitation (n=8, 13%), and extracorporeal membrane oxygenation (n=9, 14%). Patients with tachyarrhythmias had longer hospital length of stay than those who did not, and 9 (14%) versus 77 (2%) died. Conclusions Tachyarrhythmias were a rare complication of acute severe COVID-19 and multisystem inflammatory syndrome in children and adolescents and were associated with worse clinical outcomes, highlighting the importance of close monitoring, aggressive treatment, and postdischarge care.

- Abstract
Objective: Various intravenous (IV) corticosteroids are available for acute severe asthma (ASA) treatment. The choice of IV corticosteroids varies broadly and depends on institution, country, or physician preferences. In this study, we compared the efficacy of IV methylprednisolone, hydrocortisone and dexamethasone in ASA treatment during pediatric intensive care unit (PICU) admission., Methods: The study was a prospective randomized clinical trial. We enrolled patients of 1-21 years after they were admitted to the PICU requiring continuous beta-2 agonist treatment. Patients were randomized into three groups: Group A: IV Methylprednisolone, Group B: IV Hydrocortisone and Group C: IV Dexamethasone. The primary outcomes measured were durations of beta-2 agonist continuous nebulization treatment. Secondary outcomes, included PICU and hospital length of stay (LOS), pediatric asthma severity score (PASS), need for mechanical ventilation and maximum dose of beta-2 agonist treatment., Results: 61 patients were included in the analysis. 22 patients recruited in Group A, 20 in group B and 19 group C. Median durations of beta-2-agonist treatment were 23 h (QR 16-38) for methylprednisolone, 27 h (QR 16-40) for hydrocortisone, and 32 h (QR 16-48) for dexamethasone ( p = 0.90). There was no difference in PICU LOS, hospital LOS, PASS score, B2 agonist maximum dose, or need for ventilation support., Conclusions: The use of IV methylprednisolone, hydrocortisone, and dexamethasone have equivalent efficacy when used at the appropriate doses. Studies with larger cohorts are needed to compare the effectiveness of IV corticosteroids in the management of ASA in the PICU setting.

- Abstract
Introduction: Corticosteroids are important part of acute severe asthma (ASA) management in pediatric intensive care units. Few studies look at the efficacy of inhaled corticosteroids (ICS) in critical care settings. We aimed to investigate the potential beneficial effects of ICS when added to intravenous corticosteroids in pediatric patients with ASA admitted to the pediatric intensive care unit (PICU)., Methods: This was a randomized controlled trial involving pediatric patients aged 1-21 years admitted to PICU with ASA. Patients were randomized into 2 groups using block randomization. Patients in Group A received intravenous methylprednisolone (2 mg/kg/day) alone and patients in Group B received intravenous methylprednisolone (2 mg/kg/day) plus budesonide nebulization (0.5 mg every 12 h). Main outcomes were duration of continuous albuterol treatment, PICU and hospital length of stay (LOS), and need and duration of respiratory support. Kruskal-Wallis and Chi-square tests were used for statistical analysis, in which a p-value < 0.05 was considered statistically significant., Results: Duration of continuous albuterol treatment was not different between the 2 groups median/(QR), 30/(18-51) vs. 25/(14-49). ( p = 0.38) PICU and hospital LOS between the 2 groups was similar, median/(QR), 44/(30-64) vs. 46/(30-62), ( p = 0.75) and 78/(65-95) vs.72/(58-92), ( p = 0.19). Number of patients requiring respiratory support was 22(58%) in Group A and 25(64%) in Group B ( p = 0.19)., Conclusions: In critically ill children with ASA, intravenous methylprednisolone combined with inhaled budesonide did not shorten the duration of continuous albuterol inhalation treatment, the PICU and hospital LOS, and the need for respiratory support.

- Abstract
Background: Multisystem inflammatory syndrome in children (MIS-C) consensus criteria were designed for maximal sensitivity and therefore capture patients with acute COVID-19 pneumonia., Methods: We performed unsupervised clustering on data from 1,526 patients (684 labeled MIS-C by clinicians) <21 years old hospitalized with COVID-19-related illness admitted between 15 March 2020 and 31 December 2020. We compared prevalence of assigned MIS-C labels and clinical features among clusters, followed by recursive feature elimination to identify characteristics of potentially misclassified MIS-C-labeled patients., Findings: Of 94 clinical features tested, 46 were retained for clustering. Cluster 1 patients ( N = 498; 92% labeled MIS-C) were mostly previously healthy (71%), with mean age 7·2 ± 0·4 years, predominant cardiovascular (77%) and/or mucocutaneous (82%) involvement, high inflammatory biomarkers, and mostly SARS-CoV-2 PCR negative (60%). Cluster 2 patients ( N = 445; 27% labeled MIS-C) frequently had pre-existing conditions (79%, with 39% respiratory), were similarly 7·4 ± 2·1 years old, and commonly had chest radiograph infiltrates (79%) and positive PCR testing (90%). Cluster 3 patients ( N = 583; 19% labeled MIS-C) were younger (2·8 ± 2·0 y), PCR positive (86%), with less inflammation. Radiographic findings of pulmonary infiltrates and positive SARS-CoV-2 PCR accurately distinguished cluster 2 MIS-C labeled patients from cluster 1 patients., Interpretation: Using a data driven, unsupervised approach, we identified features that cluster patients into a group with high likelihood of having MIS-C. Other features identified a cluster of patients more likely to have acute severe COVID-19 pulmonary disease, and patients in this cluster labeled by clinicians as MIS-C may be misclassified. These data driven phenotypes may help refine the diagnosis of MIS-C., Competing Interests: All authors report receiving funding from the Centers for Disease Control and Prevention for the current study.

- Abstract
Importance: Coronavirus disease 2019 (COVID-19) affects the nervous system in adult patients. The spectrum of neurologic involvement in children and adolescents is unclear., Objective: To understand the range and severity of neurologic involvement among children and adolescents associated with COVID-19., Setting, Design, and Participants: Case series of patients (age <21 years) hospitalized between March 15, 2020, and December 15, 2020, with positive severe acute respiratory syndrome coronavirus 2 test result (reverse transcriptase-polymerase chain reaction and/or antibody) at 61 US hospitals in the Overcoming COVID-19 public health registry, including 616 (36%) meeting criteria for multisystem inflammatory syndrome in children. Patients with neurologic involvement had acute neurologic signs, symptoms, or diseases on presentation or during hospitalization. Life-threatening involvement was adjudicated by experts based on clinical and/or neuroradiologic features., Exposures: Severe acute respiratory syndrome coronavirus 2., Main Outcomes and Measures: Type and severity of neurologic involvement, laboratory and imaging data, and outcomes (death or survival with new neurologic deficits) at hospital discharge., Results: Of 1695 patients (909 [54%] male; median [interquartile range] age, 9.1 [2.4-15.3] years), 365 (22%) from 52 sites had documented neurologic involvement. Patients with neurologic involvement were more likely to have underlying neurologic disorders (81 of 365 [22%]) compared with those without (113 of 1330 [8%]), but a similar number were previously healthy (195 [53%] vs 723 [54%]) and met criteria for multisystem inflammatory syndrome in children (126 [35%] vs 490 [37%]). Among those with neurologic involvement, 322 (88%) had transient symptoms and survived, and 43 (12%) developed life-threatening conditions clinically adjudicated to be associated with COVID-19, including severe encephalopathy (n = 15; 5 with splenial lesions), stroke (n = 12), central nervous system infection/demyelination (n = 8), Guillain-Barré syndrome/variants (n = 4), and acute fulminant cerebral edema (n = 4). Compared with those without life-threatening conditions (n = 322), those with life-threatening neurologic conditions had higher neutrophil-to-lymphocyte ratios (median, 12.2 vs 4.4) and higher reported frequency of D-dimer greater than 3 μg/mL fibrinogen equivalent units (21 [49%] vs 72 [22%]). Of 43 patients who developed COVID-19-related life-threatening neurologic involvement, 17 survivors (40%) had new neurologic deficits at hospital discharge, and 11 patients (26%) died., Conclusions and Relevance: In this study, many children and adolescents hospitalized for COVID-19 or multisystem inflammatory syndrome in children had neurologic involvement, mostly transient symptoms. A range of life-threatening and fatal neurologic conditions associated with COVID-19 infrequently occurred. Effects on long-term neurodevelopmental outcomes are unknown.

- Abstract
Importance: Refinement of criteria for multisystem inflammatory syndrome in children (MIS-C) may inform efforts to improve health outcomes., Objective: To compare clinical characteristics and outcomes of children and adolescents with MIS-C vs those with severe coronavirus disease 2019 (COVID-19)., Setting, Design, and Participants: Case series of 1116 patients aged younger than 21 years hospitalized between March 15 and October 31, 2020, at 66 US hospitals in 31 states. Final date of follow-up was January 5, 2021. Patients with MIS-C had fever, inflammation, multisystem involvement, and positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) or antibody test results or recent exposure with no alternate diagnosis. Patients with COVID-19 had positive RT-PCR test results and severe organ system involvement., Exposure: SARS-CoV-2., Main Outcomes and Measures: Presenting symptoms, organ system complications, laboratory biomarkers, interventions, and clinical outcomes. Multivariable regression was used to compute adjusted risk ratios (aRRs) of factors associated with MIS-C vs COVID-19., Results: Of 1116 patients (median age, 9.7 years; 45% female), 539 (48%) were diagnosed with MIS-C and 577 (52%) with COVID-19. Compared with patients with COVID-19, patients with MIS-C were more likely to be 6 to 12 years old (40.8% vs 19.4%; absolute risk difference [RD], 21.4% [95% CI, 16.1%-26.7%]; aRR, 1.51 [95% CI, 1.33-1.72] vs 0-5 years) and non-Hispanic Black (32.3% vs 21.5%; RD, 10.8% [95% CI, 5.6%-16.0%]; aRR, 1.43 [95% CI, 1.17-1.76] vs White). Compared with patients with COVID-19, patients with MIS-C were more likely to have cardiorespiratory involvement (56.0% vs 8.8%; RD, 47.2% [95% CI, 42.4%-52.0%]; aRR, 2.99 [95% CI, 2.55-3.50] vs respiratory involvement), cardiovascular without respiratory involvement (10.6% vs 2.9%; RD, 7.7% [95% CI, 4.7%-10.6%]; aRR, 2.49 [95% CI, 2.05-3.02] vs respiratory involvement), and mucocutaneous without cardiorespiratory involvement (7.1% vs 2.3%; RD, 4.8% [95% CI, 2.3%-7.3%]; aRR, 2.29 [95% CI, 1.84-2.85] vs respiratory involvement). Patients with MIS-C had higher neutrophil to lymphocyte ratio (median, 6.4 vs 2.7, P < .001), higher C-reactive protein level (median, 152 mg/L vs 33 mg/L; P < .001), and lower platelet count (<150 ×103 cells/μL [212/523 {41%} vs 84/486 {17%}, P < .001]). A total of 398 patients (73.8%) with MIS-C and 253 (43.8%) with COVID-19 were admitted to the intensive care unit, and 10 (1.9%) with MIS-C and 8 (1.4%) with COVID-19 died during hospitalization. Among patients with MIS-C with reduced left ventricular systolic function (172/503, 34.2%) and coronary artery aneurysm (57/424, 13.4%), an estimated 91.0% (95% CI, 86.0%-94.7%) and 79.1% (95% CI, 67.1%-89.1%), respectively, normalized within 30 days., Conclusions and Relevance: This case series of patients with MIS-C and with COVID-19 identified patterns of clinical presentation and organ system involvement. These patterns may help differentiate between MIS-C and COVID-19.

- Abstract
Objectives: To describe the clinical manifestations and outcomes of critically ill children with coronavirus disease-19 (COVID-19) in New York City., Study Design: Retrospective observational study of children 1 month to 21 years admitted March 14 to May 2, 2020, to 9 New York City pediatric intensive care units (PICUs) with severe acute respiratory syndrome coronavirus 2 infection., Results: Of 70 children admitted to PICUs, median age was 15 (IQR 9, 19) years; 61.4% male; 38.6% Hispanic; 32.9% black; and 74.3% with comorbidities. Fever (72.9%) and cough (71.4%) were the common presenting symptoms. Twelve patients (17%) met severe sepsis criteria; 14 (20%) required vasopressor support; 21 (30%) developed acute respiratory distress syndrome (ARDS); 9 (12.9%) met acute kidney injury criteria; 1 (1.4%) required renal-replacement therapy, and 2 (2.8%) had cardiac arrest. For treatment, 27 (38.6%) patients received hydroxychloroquine; 13 (18.6%) remdesivir; 23 (32.9%) corticosteroids; 3 (4.3%) tocilizumab; and 1 (1.4%) anakinra; no patient was given immunoglobulin or convalescent plasma. Forty-nine (70%) patients required respiratory support: 14 (20.0%) noninvasive mechanical ventilation, 20 (28.6%) invasive mechanical ventilation (IMV), 7 (10%) prone position, 2 (2.8%) inhaled nitric oxide, and 1 (1.4%) extracorporeal membrane oxygenation. Nine (45%) of the 20 patients requiring IMV were extubated by day 14 with median IMV duration of 218 (IQR 79, 310.4) hours. Presence of ARDS was significantly associated with duration of PICU and hospital stay, and lower probability of PICU and hospital discharge at hospital day 14 (P < .05 for all)., Conclusions: Critically ill children with COVID-19 predominantly are adolescents, have comorbidities, and require some form of respiratory support. The presence of ARDS is significantly associated with prolonged PICU and hospital stay., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Consequently, experiencing mock codes scenarios can provide an opportunity to increase residents' confidence and knowledge in managing pediatric emergencies. Hypothesis . Pediatric senior residents perform better as code team leaders if they are exposed to frequent mock codes. Material and Methods . Forty-three pediatric senior residents (postgraduate year [PGY] two and three) participated in the study. Team leader performance was assessed utilizing the Team Emergency Assessment Measure (TEAM) scoring. Residents' team leadership performance was assessed before and 6 months after the implementation of weekly mock codes. Results . Pediatric residents' team leadership performance in mock codes improved after exposure to weekly practice mock code sessions (71.93 ± 18.50 vs 81.44 ± 11.84, P = 0.01). Conclusion . Increasing the frequency of mock code sessions during residency training led to an improvement in code team leadership performance in pediatric senior residents., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

- Abstract
Background: Understanding the epidemiology and clinical course of multisystem inflammatory syndrome in children (MIS-C) and its temporal association with coronavirus disease 2019 (Covid-19) is important, given the clinical and public health implications of the syndrome., Methods: We conducted targeted surveillance for MIS-C from March 15 to May 20, 2020, in pediatric health centers across the United States. The case definition included six criteria: serious illness leading to hospitalization, an age of less than 21 years, fever that lasted for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on reverse-transcriptase polymerase chain reaction (RT-PCR), antibody testing, or exposure to persons with Covid-19 in the past month. Clinicians abstracted the data onto standardized forms., Results: We report on 186 patients with MIS-C in 26 states. The median age was 8.3 years, 115 patients (62%) were male, 135 (73%) had previously been healthy, 131 (70%) were positive for SARS-CoV-2 by RT-PCR or antibody testing, and 164 (88%) were hospitalized after April 16, 2020. Organ-system involvement included the gastrointestinal system in 171 patients (92%), cardiovascular in 149 (80%), hematologic in 142 (76%), mucocutaneous in 137 (74%), and respiratory in 131 (70%). The median duration of hospitalization was 7 days (interquartile range, 4 to 10); 148 patients (80%) received intensive care, 37 (20%) received mechanical ventilation, 90 (48%) received vasoactive support, and 4 (2%) died. Coronary-artery aneurysms (z scores ≥2.5) were documented in 15 patients (8%), and Kawasaki's disease-like features were documented in 74 (40%). Most patients (171 [92%]) had elevations in at least four biomarkers indicating inflammation. The use of immunomodulating therapies was common: intravenous immune globulin was used in 144 (77%), glucocorticoids in 91 (49%), and interleukin-6 or 1RA inhibitors in 38 (20%)., Conclusions: Multisystem inflammatory syndrome in children associated with SARS-CoV-2 led to serious and life-threatening illness in previously healthy children and adolescents.

- Abstract
Objectives . We assessed pediatric residents' retention of knowledge and clinical skills according to the time since their last American Heart Association Pediatric Advanced Life Support (AHA PALS) certification. Methods . Sixty-four pediatric residents were recruited and divided into 3 groups based on the time since their last PALS certification, as follows: group 1, 0 to 8 months; group 2, 9 to 16 months, and group 3, 17 to 24 months. Residents' knowledge was tested using 10 multiple-choice AHA PALS pretest questions and their clinical skills performance was assessed with simulation mock code scenarios using 2 different AHA PALS checklists, and mean scores were calculated for the 3 groups. Differences in the test scores and overall clinical skill performances among the 3 groups were analyzed using analyses of variance, χ
2 tests, and Jonckheere-Terpstra tests. Statistical significance was set at P < .05. Results . The pediatric residents' mean overall clinical skills performance scores declined within the first 8 months after their last AHA PALS certification date and continued to decrease over time (87%, 82.6%, and 77.4% for groups 1, 2, and 3, respectively; P = .048). Residents' multiple-choice test scores declined in all 3 groups, but the scores were not significantly different. Conclusions . Residents' clinical skills performance declined within the first 8 months after PALS certification and continued to decline as the time from the last certification increased. Using mock code simulations and reinforcing AHA PALS guidelines during pediatric residency deserve further evaluation., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.- Published

- Abstract
Objectives: The use of continuous intravenous terbutaline treatment in severe asthma attacks has been hampered by the lack of well-powered clinical trials where effects of such treatment are described in detail. Here, we aimed to provide a descriptive report on the largest cohort of severe pediatric asthma patients treated with terbutaline., Methods: The study was conducted in a pediatric intensive care unit in a large metropolitan tertiary care university hospital on 124 patients receiving terbutaline infusion. To stratify the effect of, and determine any age-related differences of, terbutaline, the patients were divided into 3 age groups (0-6 years, 7-12 years, and 13-18 years). Clinical response and the potential harmful effects of terbutaline infusion were determined., Results: There were significant reductions in systolic (varying between 86% and 93% of the baseline) and diastolic blood pressures (varying between 74% and 86% of the baseline level). However, the values returned to baseline level shortly after discontinuation of infusion. Terbutaline increased heart rates in all groups shortly after initiation (9%-13% above baseline), which returned to below baseline levels 1 hour after discontinuation. Serum potassium levels were also reduced in all patients compared to their baseline values after initiation of terbutaline infusion. However, none of the subjects required potassium replacement., Conclusions: The results indicate that overall, terbutaline infusion was well tolerated without irreversible adverse effects of the treatment. Although hemodynamic and metabolic disturbances occurred, these were clinically easily managed and posed little risk in emergency department or pediatric intensive care unit.

- Abstract
Background: Up to 40% of infants with persistent pulmonary hypertension (PPHN) remains refractory to conventional therapies, and extracorporeal membrane oxygenation (ECMO) is offered as an effective support for this group. However, ECMO is a highly invasive and risky procedure with devastating complications such as intracranial hemorrhage (ICH). In this study, we aimed to determine the risk factors for ICH in infants with PPHN., Methods: A case-control study of patients admitted to the pediatric intensive care unit (PICU) with PPHN requiring ECMO support was conducted. The study was carried out at a 25-bed PICU in large urban tertiary care children's hospital. A total number of 32 subjects were studied. Patients with and without ICH during ECMO were evaluated for activated clotting time (ACT), heparin dosing, platelet count, coagulation profile such as activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR), fibrinogen level, vital signs including heart rate and mean arterial pressure (MAP), transfusion history, gestational age, and severity of pre-ECMO illness as possible risk factors., Results: Low fibrinogen level (115 ± 13 mg/dl) and low platelet counts (37.4 ± 18.3 Thousand/μl) were associated with higher incidence of ICH (p = 0.009 and p = 0.005, respectively). Elevated MAP (69 ± 4.34 mmHg) was also noticed in ICH patients (p = 0.006)., Conclusions: Results demonstrated that low fibrinogen level and low platelet count were associated with ICH in PPHN patients on ECMO. While on ECMO support, maintaining fibrinogen and platelet counts within normal ranges seems crucial to prevent ICH in PPHN patients. This is the first report identifying low fibrinogen level among the risk factors for ICH in infants with PPHN on ECMO support.

- Abstract
Background: Severe pediatric asthma, if not immediately and aggressively treated, may progress to acute respiratory failure requiring mechanical ventilation in the pediatric intensive care unit (PICU). Intravenous (IV) terbutaline, a β2 agonist, is dispensed when the initial treatment does not improve the clinical condition., Objective: To investigate the influence of early initiation of IV terbutaline on the incidence of acute respiratory failure requiring mechanical ventilation in severe pediatric asthma., Methods: A retrospective chart review was conducted of 120 subjects (35 patients from an outside hospital emergency department [ED] with late start of terbutaline and 85 patients from the authors' hospital ED with early initiation of IV terbutaline) admitted to the PICU with severe asthma treated with continuous IV terbutaline. Responses to terbutaline treatment and outcomes were evaluated., Results: Patients transported from outlying hospital EDs had shorter pre-PICU mean durations of IV terbutaline than those transferred from the authors' ED (0.69 ± 1.38 and 2.91 ± 2.47 hours, respectively, P = .001). Twenty-one of 35 patients (60%) from outlying EDs required mechanical ventilation compared with 14 of 85 patients (16%) from the authors' ED (P = .001). Durations of pre-PICU terbutaline infusion for patients requiring mechanical ventilation were significantly shorter than those with no such requirement (P = .015)., Conclusion: The results of the present study, conducted in the largest number of subjects to date, suggest that early administration of continuous terbutaline in the ED may decrease acute respiratory failure and the need for mechanical respiratory (invasive and noninvasive) support in severe pediatric asthma., (Copyright © 2014 American College of Allergy, Asthma & Immunology.

- Abstract
Spontaneous spinal epidural hematoma (SSEH) is a rare condition, often causing significant neurologic morbidity owing to its insidious nature and difficulty in diagnosis. Initial nonspecific clinical findings make the timely diagnosis challenging. A variety of underlying etiologies predispose patients to SSEH such as anticoagulation therapy, bleeding diatheses, vascular malformations, tumors, as well as spontaneous and idiopathic cases. Early diagnosis and intervention are critical for optimal patient outcomes. Here, we present a case of SSEH where coagulopathy was originating from underlying cholestasis. This, to our knowledge, represents the first case reported in the literature where a primary cholestatic disease is the underlying etiology.
