Diastolic/systolic blood pressure ratio for predicting febrile children with sepsis and progress to septic shock in the emergency department. BMC Emerg Med 2024; 24:78. [PMID: 38693496 PMCID: PMC11064385 DOI: 10.1186/s12873-024-00995-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Accepted: 04/24/2024] [Indexed: 05/03/2024] Open
Abstract
OBJECTIVE Given the scarcity of studies analyzing the clinical predictors of pediatric septic cases that would progress to septic shock, this study aimed to determine strong predictors for pediatric emergency department (PED) patients with sepsis at risk for septic shock and mortality. METHODS We conducted chart reviews of patients with ≥ 2 age-adjusted quick Sequential Organ Failure Assessment score (qSOFA) criteria to recognize patients with an infectious disease in two tertiary PEDs between January 1, 2021, and April 30, 2022. The age range of included patients was 1 month to 18 years. The primary outcome was development of septic shock within 48 h of PED attendance. The secondary outcome was sepsis-related 28-day mortality. Initial important variables in the PED and hemodynamics with the highest and lowest values during the first 24 h of admission were also analyzed. RESULTS Overall, 417 patients were admitted because of sepsis and met the eligibility criteria for the study. Forty-nine cases progressed to septic shock within 48 h after admission and 368 were discharged without progression. General demographics, laboratory data, and hemodynamics were analyzed by multivariate analysis. Only the minimum diastolic blood pressure/systolic blood pressure ratio (D/S ratio) during the first 24 h after admission remained as an independent predictor of progression to septic shock and 28-day mortality. The best cutoff values of the D/S ratio for predicting septic shock and 28-day mortality were 0.52 and 0.47, respectively. CONCLUSIONS The D/S ratio is a practical bedside scoring system in the PED and had good discriminative ability in predicting the progression of septic shock and in-hospital mortality in PED patients. Further validation is essential in other settings.

Predicting factors for acute encephalopathy in febrile seizure children with SARS-CoV-2 omicron variant: a retrospective study. BMC Pediatr 2024; 24:211. [PMID: 38528535 DOI: 10.1186/s12887-024-04699-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 03/11/2024] [Indexed: 03/27/2024] Open
Abstract
BACKGROUND SARS-CoV-2 posed a threat to children during the early phase of Omicron wave because many patients presented with febrile seizures. The study aimed to investigate predicting factors for acute encephalopathy of children infected by SARS-CoV-2 Omicron variant presenting with febrile seizures. METHODS The retrospective study analyzed data from pediatric patients who visited the emergency department of Chang Gung Memorial Hospital in Taiwan between April and July 2022. We specifically focused on children with COVID-19 who presented with febrile seizures, collecting demographic, clinical, and laboratory data at the pediatric emergency department, as well as final discharge diagnoses. Subsequently, we conducted a comparative analysis of the clinical and laboratory characteristics between patients diagnosed with acute encephalopathy and those with other causes of febrile seizures. RESULTS Overall, 10,878 children were included, of which 260 patients presented with febrile seizures. Among them, 116 individuals tested positive for SARS-CoV-2 and of them, 14 subsequently developed acute encephalopathy (12%). Those with acute encephalopathy displayed distinctive features, including older age (5.1 vs. 2.6 years old), longer fever duration preceding the first seizure (1.6 vs. 0.9 days), cluster seizure (50% vs. 16.7%), status epilepticus (50% vs. 13.7%) and occurrences of bradycardia (26.8% vs. 0%) and hypotension (14.3% vs. 0%) in the encephalopathy group. Besides, the laboratory findings in the encephalopathy group are characterized by hyperglycemia (mean (95% CI) 146 mg/dL (95% CI 109-157) vs. 108 mg/dL (95% CI 103-114) and metabolic acidosis (mean (95% CI) pH 7.29(95% CI 7.22-7.36) vs. 7.39 (95%CI 7.37-7.41)). CONCLUSIONS In pediatric patients with COVID-19-related febrile seizures, the occurrence of seizures beyond the first day of fever, bradycardia, clustered seizures, status epilepticus, hyperglycemia, and metabolic acidosis should raise concerns about acute encephalitis/encephalopathy. However, the highest body temperature and the severity of leukocytosis or C-reactive protein levels were not associated with poor outcomes.

Reflecting on the 1998 enterovirus outbreak: A 25-year retrospective and learned lessons. Biomed J 2024:100715. [PMID: 38492637 DOI: 10.1016/j.bj.2024.100715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 11/13/2023] [Accepted: 03/06/2024] [Indexed: 03/18/2024] Open
Abstract
Enterovirus A71 (EV-A71) infections pose a significant public health concern in the Asia-Pacific region. EV-A71 is primarily responsible for causing hand, foot, and mouth disease (HFMD) in children. However, this virus can also lead to severe and potentially fatal neurological consequences in affected individuals. This review aims to provide a comprehensive understanding of the molecular virology, epidemiology, and recombination events associated with EV-A71. The literature extensively covers the clinical manifestations and neurological symptoms that accompany EV-A71 infections. One of the complications explored in this review is brainstem encephalitis, which can arise as a result of EV-A71 infections. Brainstem encephalitis refers to inflammation of the brainstem, a critical region responsible for various bodily functions. The review examines the underlying mechanisms, diagnostic criteria, treatment options, and prognosis for central nervous system infections involving EV-A71. Neurological complications associated with EV-A71 infections are diverse and can have severe consequences. These complications may include aseptic meningitis, acute flaccid paralysis, and acute transverse myelitis. The review delves into the pathophysiology of these complications, shedding light on the molecular mechanisms through which EV-A71 affects the central nervous system. Accurate diagnosis of EV-A71 infections is crucial for appropriate management and treatment. Treatment options for EV-A71 infections primarily focus on supportive care, as there are currently no specific antiviral drugs available for this virus. The review highlights the importance of managing symptoms, such as fever, dehydration, and pain relief, to alleviate the burden on affected individuals. Prognosis for individuals with central nervous system (CNS) infections involving EV-A71 can vary depending on the severity of the complications. The review provides insights into the long-term outcomes and potential neurological sequelae associated with EV-A71 infections. In conclusion, EV-A71 infections have emerged as a major public health concern in the Asia-Pacific region. This review aims to enhance our understanding of the molecular virology, epidemiology, and neurological complications associated with EV-A71. By examining the underlying mechanisms, diagnostic criteria, treatment options, and prognosis, this review contributes to the development of effective strategies for the prevention, diagnosis, and management of EV-A71 infections. The paper presents a comprehensive analysis of worldwide data pertaining to outbreaks of EV-A71 and HFMD. The subsequent discourse delves into the advancement and strategic formulation pertaining to the creation of vaccines targeting EV-A71. In summary, this study provides a comprehensive examination of the potential obstacles and considerations involved in the management and treatment of EV-A71 infections. Additionally, it proposes suggestions for future research and development endeavors with the objective of formulating efficacious treatment approaches for this viral infection.

Ferritin as an Effective Predictor of Neurological Outcomes in Children With Acute Necrotizing Encephalopathy. Pediatr Neurol 2024; 152:162-168. [PMID: 38295717 DOI: 10.1016/j.pediatrneurol.2023.12.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 04/26/2023] [Accepted: 12/31/2023] [Indexed: 02/20/2024]
Abstract
BACKGROUND Acute necrotizing encephalopathy (ANE) is a fulminant disease with poor prognosis. Cytokine storm is the important phenomenon of ANE that affects the brain and multiple organs. The study aimed to identify whether hyperferritinemia was associated with poor prognosis in patients with ANE. METHODS All patients with ANE had multiple symmetric lesions located in the bilateral thalami and other regions such as brainstem tegmentum, cerebral white matter, and cerebellum. Neurological outcome at discharge was evaluated by pediatric neurologists using the Pediatric Cerebral Performance Category Scale. All risk factors associated with poor prognosis were further analyzed using receiver operating characteristic curve analysis. RESULTS Twenty-nine patients with ANE were enrolled in the current study. Nine (31%) patients achieved a favorable neurological outcome, and 20 (69%) patients had poor neurological outcomes. results The group of poor neurological outcome had significantly higher proportion of shock on admission and brainstem involvement. Based on multivariate logistic regression analysis, ferritin, aspartate aminotransferase (AST), and ANE severity score (ANE-SS) were the predictors associated with outcomes. The appropriate cutoff value for predicting neurological outcomes in patients with ANE was 1823 ng/mL for ferritin, 78 U/L for AST, and 4.5 for ANE-SS. Besides, comparison analyses showed that higher level of ferritin and ANE-SS were significantly correlated with brainstem involvement (P < 0.05). CONCLUSIONS Ferritin may potentially be a prognostic factor in patients with ANE. Hyperferritinemia is associated with poor neurological outcomes in patients with ANE and ferritin levels more than 1823 ng/mL have about eightfold increased risk of poor neurological outcome.

Abstract
INTRODUCTION This study aims to evaluate prognostic factors and outcomes in a single-center PICU cohort that received continuous renal replacement therapy (CRRT). METHODS This retrospective study analyzed clinical characteristics, laboratory data, and outcomes. Ninety-day mortality and advanced chronic kidney disease (CKD) (eGFR <60 ml/min/1.73m2) were defined as primary and secondary outcomes, respectively. RESULTS Seventy-five patients were enrolled, all of whom received CRRT for indications including acute kidney injury with complicated refractory metabolic acidosis, electrolyte derangement, and existed or impending fluid overload. The 90-day mortality and advanced CKD were 53% and 29%, respectively. Multivariate Cox regression analysis demonstrated that only underlying bone marrow transplantation (BMT) (HR 4.58; 95% CI 2.04-10.27) and a high pSOFA score (HR 1.12; 95% CI 1.01-1.23) were independent risk factors for 90-day mortality. Among survivors, ten developed advanced CKD on the 90th day, and this group had a higher serum fibrinogen level (OR 1.01; 95% CI 1.01-1.03) at the start of CRRT. CONCLUSION In critically ill children with AKI requiring CRRT, post-BMT and high pSOFA scores are independent risk factors for 90-day mortality. Additionally, a high serum fibrinogen level at the initiation of CRRT is associated with the development of advanced CKD.

Abstract
Children have been reported to be less affected and to have milder severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than adults during the coronavirus disease 2019 (COVID-19) pandemic. However, children, and particularly those with underlying disorders, are still likely to develop critical illnesses. In the case of SARS-CoV-2 infection, most previous studies have focused on adult patients. To aid in the knowledge of in-hospital care of children with COVID-19, this study presents an expert review of the literature, including the management of respiratory distress or failure, extracorporeal membrane oxygenation (ECMO), multisystem inflammatory syndrome in children (MIS-C), hemodynamic and other organ support, pharmaceutical therapies (anti-viral drugs, anti-inflammatory or antithrombotic therapies) and management of cardiopulmonary arrest.

Diastolic blood pressure impact on pediatric refractory septic shock outcomes. Pediatr Neonatol 2023:S1875-9572(23)00183-3. [PMID: 38016871 DOI: 10.1016/j.pedneo.2023.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 11/01/2022] [Accepted: 02/09/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND Septic shock is the progression of sepsis, defined as cardiovascular dysfunction during systemic infection, and it has a mortality rate of 40 %-80 %. Loss of vascular tone is an important pathophysiological feature of septic shock. Diastolic blood pressure (DBP) was reported to be associated with vascular tone. This study aimed to identify the associations of several hemodynamic indices, especially DBP, with outcome in pediatric septic shock to allow for timely interventions. METHODS Children with persistent catecholamine-resistant shock had a pulse index continuous cardiac output (PiCCO®) system implanted for invasive hemodynamic monitoring and were enrolled in the current study. Serial cardiac index, systemic vascular resistance index (SVRI), systolic blood pressure (SBP), mean arterial pressure (MAP), and DBP were recorded during the first 24 h following PiCCO® initiation. All hemodynamic parameters associated with 28-day mortality were further analyzed using receiver operating characteristic curve analysis. RESULTS Thirty-three children with persistent catecholamine-resistant shock were enrolled. The median age was 12 years and the youngest children were 5 years old. Univariate analysis noted that SVRI, SBP, MAP, and DBP were significantly higher, and shock index was significant lower, in survivors compared with non-survivors (p < 0.05). In the multivariate analysis, only SVRI and DBP remained independent predictors of 28-day mortality. DBP had the best correlation with SVRI (r = 0.718, n = 219, p < 0.001). The area under the receiver operating characteristic curves of SVRI and DBP for predicting 28-day mortality during the first 24 h of persistent catecholamine-resistant shock were >0.75, indicating a good prediction for mortality. CONCLUSIONS DBP correlated well with SVRI and it can serve as a predictor for mortality in pediatric septic shock. Furthermore, DBP was a superior discriminator of mortality when compared with SBP and MAP. A lower DBP was an independent hemodynamic factor associated with 28-day mortality.

Predictors of neurologic outcomes and mortality in physically abused and unintentionally injured children: a retrospective observation study. Eur J Med Res 2023; 28:441. [PMID: 37848955 PMCID: PMC10580634 DOI: 10.1186/s40001-023-01430-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Accepted: 10/03/2023] [Indexed: 10/19/2023] Open
Abstract
OBJECTIVES This study aimed to identify the predictors of neurologic outcomes and mortality in physically abused and unintentionally injured children admitted to intensive care units (ICUs). METHODS All maltreated children were admitted to pediatric, neurosurgical, and trauma ICUs between 2001 and 2019. Clinical factors, including age, sex, season of admission, identifying settings, injury severity score, etiologies, length of stay in the ICU, neurologic outcomes, and mortality, were analyzed and compared between the physically abused and unintentionally injured groups. Neurologic assessments were conducted using the Pediatric Cerebral Performance Category scale. The study was approved by the Institutional Review Board of Chang Gung Memorial Hospital and the Ethics Committee waived the requirement for informed consent because of the anonymized nature of the data. RESULTS A total of 2481 children were investigated; of them, there were 480 (19.3%) victims admitted to the ICUs, including 156 physically abused and 324 unintentionally injured. Age, history of prematurity, clinical outcomes, head injury, neurosurgical interventions, clinical manifestations, brain computed tomography findings, and laboratory findings significantly differed between them (all p < 0.05). Traumatic brain injury was the major etiology for admission to the ICU. The incidence of abusive head trauma was 87.1% among the physically abused group. Only 46 (29.4%) and 268 (82.7%) cases achieved favorable neurologic outcomes in the physically abused and unintentionally injured groups, respectively. Shock within 24 h, spontaneous hypothermia (body temperature, < 35 °C), and post-traumatic seizure were strongly associated with poor neurologic outcomes and mortality in both groups. CONCLUSIONS Initial presentation with shock, spontaneous hypothermia at ICU admission, and post-traumatic seizure were associated with poor neurologic outcomes and mortality in physically abused and unintentionally injured children.

Predictors of disease severity and outcomes in pediatric patients with croup and COVID-19 in the pediatric emergency department. Am J Emerg Med 2023; 72:20-26. [PMID: 37453221 DOI: 10.1016/j.ajem.2023.06.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 06/14/2023] [Accepted: 06/30/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Croup caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging disease, and data on the risk factors associated with disease severity are still limited. The Westley croup score (WS) is widely used to assess croup severity. The current study aimed to analyze biomarkers associated with the WS and clinical outcomes in patients with croup and coronavirus disease 2019 in the pediatric emergency department (PED). POPULATION AND METHOD Patients diagnosed with croup caused by SARS-CoV-2 were admitted at two PEDs. Clinical data including age, WS, length of hospital stay, initial laboratory data, and treatment were analyzed. Clinical parameters were evaluated via multivariate logistic regression analysis. The best cutoff values for predicting croup severity and outcomes were identified using the receiver operating characteristic curve. RESULT In total, 250 patients were assessed. Moreover, 128 (51.2%) patients were discharged from the PED, and 122 (48.8%) were admitted to the hospital. Mild, moderate, and severe croup accounted for 63.6% (n = 159), 32% (n = 80), and 4.4% (n = 11) of all cases, respectively. A high mean age (years), neutrophil count (%), neutrophil-to-lymphocyte ratio (NLR), ALT (U/L), procalcitonin (ng/mL), and hemoglobin (g/dL) level, and length of hospital stay (days), and a low lymphocyte count (%) and blood pH were associated with croup severity and need for intensive care. Based on the multivariate logistic regression model, the NLR remained independent factors associated with croup severity and prognosis. Further, NLR was significantly correlated with WS. The area under the receiver operating characteristic curve of NLR for predicting a WS of ≥3 was 0.895 (0.842-0.948, p < 0.001), and that for predicting ICU admission was 0.795 (0.711-0.879, p < 0.001). The best cutoff values for a WS of ≥3 and ICU admission were 1.65 and 2.06, respectively. CONCLUSION NLR is correlated with WS and is a reliable, easy-to-use, and cheap biomarker for the early screening and prognosis of croup severity in the PED. A higher NLR may indicate severe croup and the need for further treatment. And the WS score remains reliable for estimating the severity of croup caused by SARS-CoV-2 and the risk of intensive care.

Abstract
We present a pediatric case of acute hemorrhagic leukoencephalitis associated with SARS-CoV-2 Omicron BA 2.0 infection. A previously healthy girl presented with ataxia and diplopia three weeks after the COVID-19 confirmation from a nasopharyngeal swab. Acute and symmetrical motor weakness and drowsiness ensued within the following 3 days. She then became spastic tetraplegic. MRI revealed multifocal lesions in the cerebral white matter, basal ganglia, and brainstem, with hemorrhagic changes confirmed with T1-hyperintensity and hypointensity on susceptibility-weighted images. Peripheral areas of decreased diffusion, increased blood flow, and rim contrast enhancement were noted in the majority of lesions. She was treated with a combination of intravenous immunoglobulin and methylprednisolone pulse therapy. Neurological deterioration ensued with coma, ataxic respiratory pattern and decerebrate posture. Repeated MRI performed on day 31 revealed progression of abnormalities, hemorrhages and brain herniation. Despite the administration of plasma exchange, she died two months after admission.

Electrographic Seizures in Neonates with a High Risk of Encephalopathy. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9060770. [PMID: 35740707 PMCID: PMC9221774 DOI: 10.3390/children9060770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 04/16/2022] [Accepted: 05/14/2022] [Indexed: 11/16/2022]
Abstract
Background: Neonatal encephalopathy is caused by a wide variety of acute brain insults in newborns and presents with a spectrum of neurologic dysfunction, such as consciousness disturbance, seizures, and coma. The increased excitability in the neonatal brain appears to be highly susceptible to seizures after a variety of insults, and seizures may be the first clinical sign of a serious neurologic disorder. Subtle seizures are common in the neonatal period, and abnormal clinical paroxysmal events may raise the suspicion of neonatal seizures. Continuous video electroencephalographic (EEG) monitoring is the gold standard for the diagnosis of neonatal seizures. The aim of this study was to identify the prevalence of electrographic seizures and the impact of monitoring in neonates with a high risk of encephalopathy. Methods: We conducted this prospective cohort study in a tertiary neonatal intensive care unit over a 4-year period. Neonates with a high risk of encephalopathy who were receiving continuous video EEG monitoring were eligible. The patients were divided into 2 groups: (1) acute neonatal encephalopathy (ANE) and (2) other high-risk encephalopathy conditions (OHRs). The neonates’ demographic characteristics, etiologies, EEG background feature, presence of electrographic seizures and the impact of monitoring were analyzed. Results: A total of 71 neonates with a high risk of encephalopathy who received continuous video EEG monitoring were enrolled. In this consecutive cohort, 42 (59.2%) were monitored for ANE and 29 (40.8%) were monitored for OHRs. At the time of starting EEG monitoring, 54 (76.1%) of the neonates were term infants. The median gestational age at monitoring was 39 weeks (interquartile range, 37−41 weeks). The median total EEG monitoring duration was 64.7 h (interquartile range, 22.2−72.4 h). Electrographic seizures were captured in 25 of the 71 (35.2%) neonates, of whom 20 (80%) had electrographic-only seizures without clinical correlation. Furthermore, of these 20 neonates, 13 (65%) developed electrographic status epilepticus. Electrographic seizures were most commonly found in the ANE group (17, 40.5%) than in the OHRs group (8, 27.6%) (p = 0.013). Besides, normal/mild abnormality and inactive EEG background were less electrographic seizure than moderate and major abnormality EEG background (2 of 30, 6.7% vs. 23 of 41, 56.1%, p < 0.001). Finally, continuous video EEG monitoring excluded the diagnosis of electrographic seizures in two-thirds of the monitored neonates who had paroxysmal events mimicking seizures and led to a change in clinical management in 39.4% of the neonates. Conclusions: Our findings showed that monitoring could accurately detect seizures, and that it could be used to guide seizure medication management. Therefore, continuous video EEG monitoring has important clinical management implications in neonates with a high risk of encephalopathy.

Cutoff Values of Hemodynamic Parameters in Pediatric Refractory Septic Shock. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9030303. [PMID: 35327675 PMCID: PMC8947105 DOI: 10.3390/children9030303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 02/16/2022] [Accepted: 02/18/2022] [Indexed: 11/16/2022]
Abstract
Background: Refractory septic shock can cause severe morbidities and mortalities in children. Resuscitation based on hemodynamics is important in children with critical illness. Thus, this study aimed to identify the hemodynamics of refractory septic shock associated with poor prognosis at an early stage to allow for timely interventions. Methods: We evaluated children with refractory septic shock admitted to a pediatric intensive care unit (PICU) and monitored their hemodynamics using a pulse index continuous cardiac output (PiCCO) system. The serial cardiac index (CI), systemic vascular resistance index (SVRI), and vasoactive−inotropic score (VIS) were recorded during the first 72 h after PICU admission. Results: Thirty-three children with refractory septic shock were enrolled. The SVRI and VIS were both associated with fatality from septic shock. The non-survivors had lower serial SVRI and higher VIS (both p < 0.05). Based on the area under the ROC curve, the SVRI was the predictor during the early resuscitative stage (first 36 h) in pediatric refractory septic shock. Conclusions: Both SVRI and VIS are predictors of mortality in children with refractory septic shock, and the SVRI is the powerful predictor of mortality in the early resuscitative stage. A low serial SVRI may allow for the early awareness of disease severity and strategies for adjusting vasoactive−inotropic agents to increase the SVRI.

Abstract
BACKGROUND In general clinical practice, neonatal seizures are identified visually by direct clinical observation. The study aimed to examine the frequency of clinical seizures in paroxysmal events in a neonatal intensive care unit. METHODS We conducted a prospective study of continuous video-EEG monitoring in a neonatal intensive care unit between January 2017 and December 2020. The demographic data were also reviewed. RESULTS Sixty-four neonates were enrolled. The median total video-EEG monitoring duration was 24.1 h (IQR 17.5-44.8 h). There were 309 clinically suspected seizure episodes, of which 181 (58.6%) were the motor type and 128 (41.4%) were the non-motor type. Only 63 (20.4%) of these events were confirmed to be clinical seizures on a simultaneous video-EEG recording. In terms of the impact of continuous video-EEG monitoring on clinical management, the anti-epileptic drugs were changed in 42 (65.6%) of the 64 neonates. CONCLUSION In the identification of neonatal seizures, a clinical diagnosis by direct observation alone is not enough. The use of continuous video-EEG monitoring plays an important role in the diagnosis of neonatal seizures and in guiding clinical management decisions.

The Utility of a Point-of-Care Transcranial Doppler Ultrasound Management Algorithm on Outcomes in Pediatric Asphyxial Out-of-Hospital Cardiac Arrest – An Exploratory Investigation. Front Med (Lausanne) 2022; 8:690405. [PMID: 35155456 PMCID: PMC8832099 DOI: 10.3389/fmed.2021.690405] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Accepted: 12/31/2021] [Indexed: 11/13/2022] Open
Abstract
Background Transcranial Doppler ultrasound is a sensitive, real time tool used for monitoring cerebral blood flow; it could provide additional information for cerebral perfusion in cerebral resuscitation during post cardiac arrest care. The aim of the current study was to evaluate the utility of a point-of-care transcranial Doppler ultrasound management algorithm on outcomes in pediatric asphyxial out-of-hospital cardiac arrest. Methods This retrospective cohort study was conducted in two tertiary pediatric intensive care units between January 2013 and June 2018. All children between 1 month and 18 years of age with asphyxial out-of-hospital cardiac arrest and a history of at least 3 min of chest compressions, who were treated with therapeutic hypothermia and survived for 12 h or more after the return of circulation were eligible for inclusion. Results Twenty-one patients met the eligibility criteria for the study. Sixteen (76.2%) of the 21 children were male, and the mean age was 2.8 ± 4.1 years. Seven (33.3%) of the children had underlying disorders. The overall 1-month survival rate was 52.4%. Twelve (57.1%) of the children received point-of-care transcranial Doppler ultrasound. The 1-month survival rate was significantly higher (p = 0.03) in the point-of-care transcranial Doppler ultrasound group (9/12, 75%) than in the non-point-of-care transcranial Doppler ultrasound group (2/9, 22.2%). Conclusions Point-of-care transcranial Doppler ultrasound group was associated with a significantly better 1-month survival rate compared with no point-of-care transcranial Doppler ultrasound group in pediatric asphyxial out-of-hospital cardiac arrest.

Early High-Dose Methylprednisolone Therapy Is Associated with Better Outcomes in Children with Acute Necrotizing Encephalopathy. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9020136. [PMID: 35204857 PMCID: PMC8870393 DOI: 10.3390/children9020136] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 12/27/2021] [Accepted: 01/18/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND The neurologic outcomes of acute necrotizing encephalopathy (ANE) are very poor, with a mortality rate of up to 40% and fewer than 10% of patients surviving without neurologic deficits. Steroid and immunoglobulin treatments have been the most commonly used options for ANE, but their therapeutic efficacy is still controversial. METHOD We retrospectively reviewed the medical records of 26 children diagnosed with ANE. We also divided these patients into two groups: 21 patients with brainstem involvement and 8 patients without brainstem involvement. Pulse steroid therapy (methylprednisolone at 30 mg/kg/day for 3 days) and intravenous immunoglobulin (2 g/kg for 2-5 days) were administered to treat ANE. RESULTS The overall mortality rate was 42.3%, and patients who did not survive had significantly higher initial lactate and serum ferritin levels, as well as higher rates of inotropic agent use with brainstem involvement. There were no significant differences in the outcomes of pulse steroid therapy or pulse steroid plus immunoglobulin between survivors and non-survivors. When analyzing the time between symptom onset and usage of pulse steroid therapy, pulse steroid therapy used within 24 h after the onset of ANE resulted in significantly better outcomes (p = 0.039). In patients with brainstem involvement, the outcome was not correlated with pulse steroid therapy, early pulse steroid therapy, or pulse steroid therapy combined with immunoglobulin. All patients without brainstem involvement received "early pulse methylprednisolone" therapy, and 87.5% (7/8) of these patients had a good neurologic outcome. CONCLUSION Pulse steroid therapy (methylprednisolone at 30 mg/kg/day for 3 days) administered within 24 h after the onset of ANE may be correlated with a good prognosis. Further studies are needed to establish a consensus guideline for this fulminant disease.

Life-Threatening Enterovirus 71 Encephalitis in Unrelated Children with Autosomal Dominant TLR3 Deficiency. J Clin Immunol 2022; 42:606-617. [PMID: 35040013 DOI: 10.1007/s10875-021-01170-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 11/01/2021] [Indexed: 12/17/2022]
Abstract
PURPOSE Enterovirus A71 (EV71) causes a broad spectrum of childhood diseases, ranging from asymptomatic infection or self-limited hand-foot-and-mouth disease (HFMD) to life-threatening encephalitis. The molecular mechanisms underlying these different clinical presentations remain unknown. We hypothesized that EV71 encephalitis in children might reflect an intrinsic host single-gene defect of antiviral immunity. We searched for mutations in the toll-like receptor 3 (TLR3) gene. Such mutations have already been identified in children with herpes simplex virus encephalitis (HSE). METHODS We sequenced TLR3 and assessed the impact of the mutations identified. We tested dermal fibroblasts from a patient with EV71 encephalitis and a TLR3 mutation and other patients with known genetic defects of TLR3 or related genes, assessing the response of these cells to TLR3 agonist poly(I:C) stimulation and EV71 infection. RESULTS Three children with EV71 encephalitis were heterozygous for rare mutations-TLR3 W769X, E211K, and R867Q-all of which were shown to affect TLR3 function. Furthermore, fibroblasts from the patient heterozygous for the W769X mutation displayed an impaired, but not abolished, response to poly(I:C). We found that TLR3-deficient and TLR3-heterozygous W769X fibroblasts were highly susceptible to EV71 infection. CONCLUSIONS Autosomal dominant TLR3 deficiency may underlie severe EV71 infection with encephalitis. Human TLR3 immunity is essential to protect the central nervous system against HSV-1 and EV71. Children with severe EV71 infections, such as encephalitis in particular, should be tested for inborn errors of TLR3 immunity.

Abstract
In the pediatric intensive care unit (PICU), cardiac arrest (CA) is rare but results in high rates of morbidity and mortality. A retrospective chart review of 223 patients who suffered from in-PICU CA was analyzed from January 2017 to December 2020. Outcomes at discharge were evaluated using pediatric cerebral performance category (PCPC). Return of spontaneous circulation was attained by 167 (74.8%) patients. In total, only 58 (25%) patients survived to hospital discharge, and 49 (21.9%) of the cohort had good neurologic outcomes. Based on multivariate logistic regression analysis, vasoactive-inotropic drug usage before CA, previous PCPC scale >2, underlying hemato-oncologic disease, and total time of CPR were risk factors associated with poor outcomes. Furthermore, we determined the cutoff value of duration of CPR in predicting poor neurologic outcomes and in-hospital mortality in patients caused by in-PICU CA as 17 and 23.5 min respectively.

Household cleaning products poisoning in a pediatric emergency center: A 10- year cross-sectional study and literature review. Pediatr Neonatol 2021; 62:638-646. [PMID: 34332912 DOI: 10.1016/j.pedneo.2021.05.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 04/10/2021] [Accepted: 05/20/2021] [Indexed: 10/20/2022] Open
Abstract
BACKGROUND Poisoning by household cleaning products(HCPs) is common in children. Some HCPs are toxic and may cause severe complications. We assessed HCP poisonings treated in a pediatric emergency department(PED). METHODS This was a retrospective study of patients aged under 18 years with HCP poisoning admitted to the largest PED in Taiwan from 2011 to 2020 were recruited. RESULTS The records over a 10-year period from 103 children admitted to the PED because of HCP poisoning(70 boys [68%] and 33 girls [32%]), mean age 3.54 years(standard deviation [SD] = 3.15 years) were evaluated. Most poisonings were unintentional(99%, n = 102) and occurred at home(96%, n = 99). The HCPs included alkaline(74%, n = 76), acidic(25%, n = 26), and neutral(1%, n = 1) agents. Most were orally ingested(86%, n = 89). Panendoscopy was performed in 25 patients(24%), and the endoscopic(Zargar) grade was used to determine the severity of injury. Medications(steroids [9%, n = 9], antibiotics [10%, n = 10], or antacids [30%, n = 23]) were prescribed. Alkaline HCP ingestion induced severe esophageal injury(p = 0.04) and esophageal stricture(p = 0.04). Five patients(5%) exhibited esophageal strictures and required balloon dilation. On multivariate analysis, alkaline HCP ingestion(p = 0.04), severe esophageal caustic injury(Zargar grade ≥ 3) (p < 0.001), and medications(steroids [p < 0.001], antibiotics [p < 0.001], and antacids [p = 0.001]) were associated with esophageal stricture. CONCLUSION Alkaline HCP ingestion and severe esophageal caustic injury(Zargar grade ≥ 3) were associated with esophageal stricture. Physicians tended to prescribe medications(steroids, antibiotics, or antacids) for patients with severe esophageal injuries to reduce the risk of esophageal stricture. The usefulness of these medications requires further study.

Abstract
Sepsis remains a major cause of morbidity and mortality among children worldwide. Furthermore, refractory septic shock and multiple organ dysfunction syndrome are the most critical groups which account for a high mortality rate in pediatric sepsis, and their clinical course often deteriorates rapidly. Resuscitation based on hemodynamics can provide objective values for identifying the severity of sepsis and monitoring the treatment response. Hemodynamics in sepsis can be divided into two groups: basic and advanced hemodynamic parameters. Previous therapeutic guidance of early-goal directed therapy (EGDT), which resuscitated based on the basic hemodynamics (central venous pressure and central venous oxygen saturation (ScvO2)) has lost its advantage compared with “usual care”. Optimization of advanced hemodynamics, such as cardiac output and systemic vascular resistance, has now been endorsed as better therapeutic guidance for sepsis. Despite this, there are still some important hemodynamics associated with prognosis. In this article, we summarize the common techniques for hemodynamic monitoring, list important hemodynamic parameters related to outcomes, and update evidence-based therapeutic recommendations for optimizing resuscitation in pediatric septic shock.

Clinical survey and predictors for the development of tracheobronchomalacia in preterm infants. Pediatr Pulmonol 2021; 56:2553-2560. [PMID: 34048639 DOI: 10.1002/ppul.25445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/25/2021] [Accepted: 04/17/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Tracheobronchomalacia (TBM) contributes to the increased morbidity and mortality observed in preterm infants. Effective strategies for the prevention of TBM are necessary to achieve better outcomes. We sought to identify risk factors associated with the development of TBM in preterm infants. Optimal cut-off values for each risk factor were also determined. METHODS A total of 80 infants who were born at 36 week's gestation or earlier and underwent flexible bronchoscopy were included in our study sample. A comparison of demographic and clinical risk factors between those with TBM (n = 35, 44%) and those without TBM (n = 45, 56%) was conducted using multivariate logistic regression analysis. Receiver operating characteristic curve analysis was performed to determine the appropriate cut-off values for predicting the development of TBM. RESULTS In the multivariate analysis, only peak inspiratory pressure (PIP) and the number of intubation days remained significantly different between infants with and without TBM. Preterm infants with TBM received higher PIP (odds ratio: [OR], 1.067; 95% confidence interval [CI], 1.010-1.128; p = .020) and were intubated for longer (odds ratio [OR], 1.019; 95% CI, 1.003-1.035; p = .016) than those without TBM. Infants who received PIP > 19.5 cmH2 O or were intubated for >79.5 days were associated with a significantly higher risk of presence of TBM. CONCLUSION High PIP and prolonged intubation were major risk factors for the development of TBM in premature infants. Those who require PIP > 19.5 cmH2 O or intubation >79.5 days warrant bronchoscopy examination for early diagnosis and management of TBM.

Abstract
Aim: To identify the risk factors associated with the development of tracheobronchomalacia (TBM) in preterm infants with bronchopulmonary dysplasia (BPD). Methods: This was a retrospective cohort study using chart reviews of preterm infants born at ≤ 36 week's gestation who underwent flexible fiberoptic bronchoscopy in a tertiary pediatric referral center between January 2015 and January 2020. Indications for the bronchoscopy examination included lobar atelectasis on plain chest film, persistent CO2 retention, recurrent extubation failure, or abnormal breathing sounds such as wheeze or stridor. Optimal cutoff values for each risk factor were also determined. Results: Fifty-eight preterm infants with BPD were enrolled, of whom 29 (50%) had TBM. There were no significant differences in gestational age and birth weight between those with and without TBM. Significantly more of the patients with TBM had severe BPD compared to those without TBM (68.9 vs. 20.6%, p < 0.001). Clinical parameters that were significantly different between the two groups were included in multivariate analysis. Among these factors, severe BPD was the most powerful risk factor for the development of TBM (odds ratio 5.57, 95% confidence interval 1.32-23.5, p = 0.019). The areas under the receiver operating characteristic curves for peak inspiratory pressure (PIP) and the duration of intubation were 0.788 and 0.75, respectively. The best predictive cutoff values of PIP and duration of intubation for TBM were 18.5 mmHg and 82 days, respectively. Conclusion: Preterm infants with severe BPD are at high risk for the development of TBM, and the risk is even higher in those who receive a higher PIP or are intubated for longer. Bronchoscopy examinations should be considered for the early diagnosis and management of TBM in infants with these risk factors.

Abstract
Aim: High-flow nasal cannulas (HFNCs) show potential in the application of positive pressure, improving gas exchange, and decreasing work of breathing in patients with acute respiratory distress. The aims of this study were to elucidate the indications for HFNC therapy in children of all ages and diagnoses, and to evaluate the efficacy and risk factors for failure of HFNC therapy in children with acute respiratory distress with hypoxia in a pediatric intensive care unit. Methods: We conducted this retrospective cohort study at a tertiary pediatric intensive care unit between January 1, 2018 and December 31, 2020. All children, from 1 month to 18 years of age, with acute respiratory distress with hypoxia and HFNC therapy were eligible. The clinical data were reviewed. Results: One hundred and two children met the eligibility criteria for the study, of whom 57 (55.9%) were male, and the mean age was 7.00 6.79 years. Seventy-eight (76.5%) of the children had underlying disorders. The most common indications for the use of HFNC therapy were pneumonia (40, 39.2%), sepsis-related respiratory distress (17, 16.7%), and bronchiolitis (16, 15.7%). The failure rate was 15.7% (16 of 102 children). Higher initial and maximum fraction of inspiration O2 levels and lower initial and lowest SpO2/FiO2 (S/F) ratio were early and possible signs of failure requiring escalation of respiratory support. Conclusion: In our population, we found that HFNC therapy could be initiated as the first-line therapy for various etiologies of acute respiratory distress with hypoxia in a pediatric intensive care unit and for all age groups.

Abstract
Acute encephalitis is an important pediatric emergency that tends to be associated with neurological morbidity, critical illness, and mortality. Few data have specifically focused on evaluating various early clinical parameters in the pediatric emergency department as candidate predictors of mortality. The present retrospective study assessed the clinical, laboratory, and neuroimaging findings of children with acute encephalitis who presented to the emergency department. Of 158 patients diagnosed with encephalitis, 7 (4.4%) had mortality. Compared to the survivors, a multivariate analysis revealed that an initial Glasgow Coma Scale score ≤ 5 (odds ratio [OR]: 8.3, P = .022), acute necrotizing encephalitis (OR: 12.1, P = .01), white blood count level ≤ 5.2 × 109 cells/L (OR: 28.7, P < .001), aspartate aminotransferase level > 35 U/L (OR: 14.3, P = .022), and influenza A infection (OR: 7.7, P = .027) were significantly associated with mortality. These results indicate that the early recognition of preliminary clinical features and the development of more specific etiologies for encephalitis are important for early treatment strategies.

Abstract
Acute encephalopathy is a life-threatening disease involving acute brain dysfunction, and it is one of the most important causes of mortality and severe neurological sequelae in infants and children. Approximately 30% of cases of acute encephalopathy result in some degree of neurological sequelae. Although many strategies have been proposed, effective therapies to ameliorate the outcomes of acute encephalopathy have not yet been established. Target temperature management (TTM), previously termed therapeutic hypothermia, has been shown to be effective for various brain injuries due to multiple neuroprotective mechanisms, and it may be considered to be the cornerstone of neuroprotective strategies. Consequently, TTM is currently used in the neurocritical care of adult patients with cardiac arrest with shockable rhythm and perinatal asphyxia. In addition, increasing evidence also indicates that TTM could be useful in other acute encephalopathies, including status epilepticus, acute encephalitis/encephalopathy and traumatic brain injury. In this review, we discuss the recent practical aspects of TTM as a potential intervention for various acute encephalopathies in children.

Abstract
Background Defective human TLR3 signaling causes recurrent and refractory herpes simplex encephalitis/encephalopathy. Children with febrile infection-related epilepsy syndrome with refractory seizures may have defective TLR responses. Methods Children with febrile infection-related epilepsy syndrome were enrolled in this study to evaluate TLR1-9 responses (IL-6, IL-8, IL-12p40, INF-α, INF-γ, and TNF-α) in their peripheral blood mononuclear cells (PBMCs) and monocyte-derived dendritic cells (MDDCs), compared to those with febrile seizures and non-refractory epilepsy with/without underlying encephalitis/encephalopathy. Results Adenovirus and enterovirus were found in throat cultures of enrolled patients (2–13 years) as well as serologic IgM elevation of mycoplasma pneumonia and herpes simplex virus, although neither detectable pathogens nor anti-neural autoantibodies in the CSF could be noted. Their PBMCs and MDDCs trended to have impaired TLR responses and significantly lower in cytokine profiles of TLR3, TLR4, TLR7/8, and TLR9 responses but not other TLRs despite normal TLR expressions and normal candidate genes for defective TLR3 signaling. They also had decreased naïve T and T regulatory cells, and weakened phagocytosis. Conclusion Children with febrile infection-related epilepsy syndrome (FIRES) could have impaired TLR3, TLR4, TLR7/8, and TLR9 responses possibly relating to their weakened phagocytosis and decreased T regulatory cells.

Abstract
The rapid diagnosis of increased intracranial pressure is urgently needed for therapeutic reasons in neurocritically ill children, however this can rarely be achieved without invasive procedures. Point-of-care ultrasound of the optic nerve sheath diameter has been proposed as a non-invasive and reliable means to detect increased intracranial pressure in adults. Accordingly, clinicians may be able to use this technique to initiate early treatment and monitor the effectiveness of treatment in conjunction with other clinical examination and diagnostic modalities. Two meta-analyses and a systematic review have been published on this topic in adults. However, data on the correlation between optic nerve sheath diameter and intracranial pressure in neurocritically ill children are scarce. The aim of this review was to briefly describe what is being measured with point-of-care ultrasound of the optic nerve sheath diameter, summarize the most recent findings from adult literature, and provide an update of current work in children.

Abstract
Enterovirus A71 (EV-A71) is one of the causative pathogens of hand, foot, and mouth disease (HFMD), which may cause severe neurological and cardiopulmonary complications in children. In this review, we discuss the pathogenesis, clinical manifestations, management strategy, and clinical outcomes of cardiopulmonary failure (CPF) in patients with EV-A71 infection. The pathogenesis of CPF involves both catecholamine-related cardiotoxicity following brainstem encephalitis and vasodilatory shock due to cytokine storm. Sympathetic hyperactivity, including tachycardia and hypertension, are the early clinical manifestations of cardiopulmonary involvement, which may progress to pulmonary edema/hemorrhage and/or CPF. The management strategy comprises multidisciplinary supportive treatment, including fluid management, positive pressure ventilation support, and use of milrinone, vasopressors, and inotropes. Some patients may require extracorporeal membrane oxygenation. Major neurological sequelae are almost inevitable once a child develops life-threatening illness. Long-term care of these children is an important medico-social issue.

BACKGROUND Vasoplegia is vascular hyporesponsiveness to vasopressors and is an important phenomenon in children with refractory septic shock. This study aimed to develop an objective formula correlated with vasoplegia and evaluate the predictive power for mortality in children with refractory septic shock. MATERIALS AND METHODS We retrospectively analyzed children with refractory septic shock admitted to a pediatric intensive care unit (PICU) and monitored their hemodynamics via a pulse index continuous cardiac output (PiCCO) system. Serial hemodynamic data including cardiac index (CI), systemic vascular resistant index (SVRI) and vasoactive-inotropic score (VIS) were recorded during the first 72 hours after PICU admission. We defined vascular reactivity index (VRI) as SVRI/VIS and analyzed the effect of VRI in predicting mortality in children with refractory septic shock. RESULTS Thirty-three children with refractory septic shock were enrolled. The SVRI was lower in the mortality group compared to the survival group (P < .05). The average area under the receiver operating characteristic curve of VRI within the first 72 hours was 0.8 and the serial values of VRI were significantly lower in the mortality group during the period from 0 to 48 hours (P < .05). However, there were no significant differences in serial CI values between the survival and mortality groups. CONCLUSIONS Vasoactive-inotropic score may potentially be used to quantify the severity of vasoplegia based on the clinical response of vessels after resuscitation with vasopressors. Lower VRI levels may indicate a higher risk of mortality in children with septic shock.

Methylprednisolone pulse therapy as an adjuvant treatment of Streptococcus pneumoniae meningitis complicated by cerebral infarction-a case report and review of the literature. Childs Nerv Syst 2020; 36:229-233. [PMID: 31897636 DOI: 10.1007/s00381-019-04485-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2018] [Accepted: 12/19/2019] [Indexed: 12/19/2022]
Abstract
PURPOSE The role of methylprednisolone pulse therapy as adjuvant treatment of Streptococcus pneumoniae meningitis complicated by cerebral infarction has rarely been reported. METHODS We reported a case report and also performed a systematic literature review. RESULTS A 1-year 2-month-old boy who presented with high fever, status epilepticus, and septic shock was diagnosed with cerebral infarction caused by Streptococcus pneumoniae meningitis on magnetic resonance imaging (MRI). He was treated with methylprednisolone pulse therapy and his clinical condition gradually improved thereafter. At the follow-up visit 1 year after discharge, he was able to sit without support, but he had moderate delays in speech and developmental milestones and epilepsy sequelae. CONCLUSION In severe cases, the use of high-dose methylprednisolone should be considered to modulate the inflammatory response in patients with severe cerebral infarction caused by Streptococcus pneumoniae meningitis.

Clinical role of low hemoglobin ratio in poor neurologic outcomes in infants with traumatic intracranial hemorrhage. Sci Rep 2020; 10:400. [PMID: 31942018 PMCID: PMC6962163 DOI: 10.1038/s41598-019-57334-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 12/18/2019] [Indexed: 11/04/2022] Open
Abstract
Traumatic brain injury (TBI) is the leading cause of pediatric morbidity and mortality worldwide, and half of all fatalities occur in infants aged less than 1 year. We analyzed 129 infants diagnosed with TBI complicated with intracranial hemorrhage confirmed by brain computed tomography. We defined delta hemoglobin (ΔHB) as nadir HB - age specific mean HB, and the ratio of HB (%) as ΔHB/age specific mean HB x 100. Infants with poor neurologic outcomes had a lower admission HB and ΔHB (p < 0.05). The in-hospital mortality rate was 10.1% (13 infants), and the infants who died had a significantly lower ΔHB ratio compared to the survivors. The area under the receiving operating characteristic curve (AUC) of initial Glasgow Coma Score (GCS) in predicting neurologic outcomes was higher than that of ratio of ΔHB (0.881 v.s 0.859). In multivariate logistic regression analysis with the optimal cutoff ratio of ΔHB, it remained an independent predictor for in-hospital mortality and poor neurologic outcomes at discharge and at 6 months. AUC analysis for the ratio of ΔHB for poor neurologic outcomes in infants aged from 0–6 months was 0.85 and the optimal cutoff was −30.7% (sensitivity, 69%; specificity, 92%; positive likelihood ratio (LR+), 8.24; negative likelihood ratio (LR−), 0.34); the AUC was 0.88 in infants aged from 6–12 months and the optimal cutoff was −20.6% (sensitivity, 89%; specificity, 79%; LR+, 4.13; LR−, 0.15).

Factors Associated With In-hospital Mortality of Children With Acute Fulminant Myocarditis on Extracorporeal Membrane Oxygenation. Front Pediatr 2020; 8:488. [PMID: 32984204 PMCID: PMC7481354 DOI: 10.3389/fped.2020.00488] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Accepted: 07/13/2020] [Indexed: 11/13/2022] Open
Abstract
Aim: To analyze the factors associated with in-hospital mortality of children with acute fulminant myocarditis on venoarterial extracorporeal membrane oxygenation (VA-ECMO). Methods: This was a retrospective cohort study using chart reviews of patients diagnosed with acute fulminant myocarditis at the pediatric intensive care unit of two tertiary medical centers between January 1, 2005 and December 31, 2017. The inclusion criteria for this study were: (1) age from 1 month to 18 years; (2) diagnosed with acute myocarditis; (3) cardiogenic shock and need vasoactive-inotropic score ≥20 within 48 h after the use of vasoactive-inotropic agents; and (4) the need for ECMO placement. Results: Thirty-three children with acute fulminant myocarditis who needed ECMO were included. Clinical parameters were retrospectively reviewed. The overall survival rate was 69.6%. Higher levels of pre-ECMO troponin-I and pre-ECMO lactate, and lower post-ECMO left ventricular ejection fraction (LVEF) were significantly associated with in-hospital mortality in univariate analysis. Only higher pre-ECMO lactate and lower post-ECMO LVEF remained as predictors for in-hospital mortality in multivariate analysis. The areas under the curve of pre-ECMO lactate and post-ECMO LVEF in predicting survival were 0.848 (95% CI, 0.697-0.999, p = 0.002) and 0.824 (95% CI, 0.704-0.996, p = 0.01), respectively. A pre-ECMO lactate level of 79.8 mg/dL and post-ECMO LVEF of 39% were appropriate cutoff points to predict mortality. Conclusion: Pre-ECMO lactate level was associated with mortality in children with acute fulminant myocarditis, with an optimal cutoff value of 79.8 mg/dL. After VA-ECMO implantation, post-ECMO LVEF was associated with mortality, with an optimal cutoff value of 39%. The use of LVADs or urgent heart transplantation should be considered if the post-ECMO LVEF does not improve.

Abstract
Traumatic brain injury (TBI) is a leading cause of pediatric morbidity and mortality and is categorized as abusive head trauma (AHT) and accidental head injury. A retrospective chart review of 124 children aged <1 year diagnosed with TBI were analyzed. Outcomes were evaluated at discharge and 6 months later by using the Pediatric Cerebral Performance Category (PCPC) Scale. The receiver operating characteristic (ROC) curve was applied to determine the cutoff values for hemoglobin (HB) levels. In the study, 50 infants (40.3%) achieved a favorable neurologic outcome (PCPC ≦ 2) and 74 (59.7%) had poor neurologic outcomes (PCPC ≧ 3). Infants with poor neurologic outcomes had lower HB on admission and nadir HB (p < 0.05). Based on multivariate logistic regression analysis, the nadir HB was a predictor of poor neurologic outcomes at discharge and 6 months later in both AHT and accidental head injury. Nadir HB had the largest area under the ROC curve for predicting poor neurologic outcomes. We determined the appropriate cutoff value of nadir HB as 9.35 g/dl for predicting neurologic outcomes in infants with TBI. Furthermore, the cutoff value of nadir HB in predicting poor neurologic outcomes in infants caused by AHT and accidental head injury were taken as 9.36 and 8.75 g/dl, respectively.

Abstract
During recent 20 years, enterovirus A71 (EV-A71) has emerged as a major concern among pediatric infectious diseases, particularly in the Asia-Pacific region. The clinical manifestations of EV-A71 include uncomplicated hand, foot, and mouth disease, herpanina or febrile illness and central nervous system (CNS) involvement such as aseptic meningitis, myoclonic jerk, polio-like syndrome, encephalitis, encephalomyelitis and cardiopulmonary failure due to severe rhombencephalitis. In follow-up studies of patients with EV-A 71 CNS infection, some still have hypoventilation and need tracheostomy with ventilator support, some have dysphagia and need nasogastric tube or gastrostomy feeding, some have limb weakness/astrophy, cerebellar dysfunction, neurodevelopmental delay, lower cognition, or attention deficiency hyperactivity disorder. Long term sequelae may be related to greater severity of CNS involvement or neuron damage, hypoxia and younger age of onset.

Abstract
BACKGROUND Pediatric poisoning is a common emergency worldwide. Routine surveillance is required for public health authorities and physicians to update strategies for prevention and management of pediatric poisoning. This study investigated the epidemiology of poisoning among children admitted to an emergency department (ED). METHODS This was a retrospective descriptive study. Data were collected from patients under 18 years old (y/o) presenting with poisoning at the largest ED in North Taiwan from 2011 to 2015. RESULTS Five-year records of 590 patients-309 (52.3%) boys and 281 (47.7%) girls-were analyzed. The mean age was 5.07 y/o (Standard Deviation [SD] = 5.02 years), and 94.7% of events occurred at home. Incidence was highest from 6 p.m. to 12 a.m. (42.2%, n = 249). Most patients younger than 11 y/o were male, but this gender distribution was reversed in adolescents (11-17 y/o). Pharmaceutical ingestion (41.4%, n = 244) was the leading cause of poisoning; pesticide was the most common non-pharmaceutical poison ingested (9.5%, n = 55). Carbon monoxide (CO) intoxication (87.6%, n = 99) and snakebite (75%, n = 9) were the common causes of inhalation (n = 113) and venom (n = 12) poisoning, respectively. The mean duration of the ED stay was 5.45 h (SD = 7.39 h), and 101 cases (17.2%), including 21 cases (3.6%) requiring intensive care, were admitted to the hospital. All patients survived. CONCLUSION Most poisonings occurred in young children, at home, by unintentional ingestion of a single substance, from 6 p.m. to 12 a.m. Female adolescents were the common intentional poisoning patients and pharmaceutical ingestion was the leading cause of poisoning. This kind of information enables ED physicians to improve preparations for pediatric poisoning cases and allows public health authorities to sharpen the focus of poisoning prevention efforts.

Early Clinical Predictors of Neurological Outcome in Children With Asphyxial Out-of-Hospital Cardiac Arrest Treated With Therapeutic Hypothermia. Front Pediatr 2019; 7:534. [PMID: 32010648 PMCID: PMC6979260 DOI: 10.3389/fped.2019.00534] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Accepted: 12/09/2019] [Indexed: 11/18/2022] Open
Abstract
Aim: The aim of the current study was to identify early clinical predictors of neurologic outcome in children with asphyxial out-of-hospital cardiac arrest (OHCA) treated with therapeutic hypothermia. Methods: The present retrospective cohort study of comatose children treated with therapeutic hypothermia or normothermia after asphyxial OHCA was conducted between January 2010 and June 2018. All children aged between 1 month and 18 years of age, with a history of at least 3 min of chest compressions were eligible for inclusion. Their 6-month neurological outcomes were evaluated using the Pediatric Cerebral Performance Category (PCPC) score and early clinical predictors were determined. Results: A total of 100 patients met the eligibility criteria for the study. Sixty-four (64%) of the children were male, and the mean age of participants was 4.59 ± 5.45 years. Forty (40%) of the children had underlying disorders. The overall 1-month survival rate was 36%. Only 12 (12%) of the patients had favorable outcomes (PCPC ≤ 2). Thirty-four (34%) of the 100 children were receiving therapeutic hypothermia. In the univariate analysis, an initial lactate level of ≤ 80 mg/dL, a Glasgow coma scale (GCS) score of 5-8, a GCS motor score ≥4 and a present pupil reflex before therapeutic hypothermia, were significantly associated with favorable 6-month neurological outcomes. However, after the multivariate logistic analysis, only initial serum lactate level and GCS before therapeutic hypothermia were significantly associated with favorable 6-month neurological outcomes. Conclusion: Initial serum lactate level and GCS before therapeutic hypothermia were significantly associated with 6-month favorable neurological outcomes in pediatric asphyxial OHCA patients who were treated with therapeutic hypothermia. Therefore, these early clinical predictors could be helpful to facilitate future clinical research in children with asphyxial OHCA treated with therapeutic hypothermia.

Abstract
Child maltreatment is complicated by cultural, welfare, and socioeconomic factors. However, the relationship between child maltreatment and socioeconomic factors has not been completely understood. We investigated risk factors for child abuse and neglect in Taiwan.The data in our study was obtained from Taiwan National Statistics at county level from 2004 to 2015. We included 4 areas (eastern, western, southern, northern) involving 20 cities and counties. The trends of child maltreatment rate based on different years and different areas were surveyed. In addition, panel data analysis was used to analyze the links between child maltreatment rate and socioeconomic factors.An increasing trend of child maltreatment rate in Taiwan was observed. During the past decade, child maltreatment rate increased from 14.5 in 2004 to 23.4 cases per 10000 children in 2014. The peak, which was 43 cases per 10000 children, occurred in 2012. Significant geographical differences were observed, and the highest child maltreatment rate was seen in eastern Taiwan. Panel data analysis revealed a lag effect of the unemployment rate on child maltreatment rate at the county level: the child maltreatment rate increased by 7 percent, while the prior unemployment rate increased by one percent. In addition, the medical personnel density was related to the child maltreatment rate within the county.Previous unemployment rate had a lag impact on child maltreatment occurrence. Unemployment rate has not only a direct impact on the economy but also sequential effects on child maltreatment.

Strong correlation between doppler snuffbox resistive index and systemic vascular resistance in septic patients. J Crit Care 2018; 49:45-49. [PMID: 30366249 DOI: 10.1016/j.jcrc.2018.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2018] [Revised: 09/25/2018] [Accepted: 10/15/2018] [Indexed: 12/20/2022]
Abstract
PURPOSE To compare systemic vascular resistance index (SVRI) as measured by invasive transpulmonary indicator dilution (TPID) and non-invasive Doppler-derived resistive index in septic patients. METHODS We measured the snuffbox resistive index (SBRI) in both hands of septic patients who received hemodynamic monitoring by TPID prospectively. RESULTS Thirty-six patients with septic shock were enrolled (median acute physiology and chronic health evaluation II score: 23; median age: 64 years). Four SBRI values were measured in each patient, for a total of 96 patient days and 951 ultrasound measurements. The correlation coefficients between SVRI and the four SBRI values were all higher than 0.87 (p < .001). A higher SVRI was associated with sharp waveforms and reversed diastolic flow. A resistive index (RI) of 0.97 was the lower limit of normal SVRI (1700 dyn*s*cm-5*m2), and an RI of 1.1 was the upper limit of normal SVRI (2400 dyn*s*cm-5*m2). CONCLUSIONS Using ultrasound to measure RI is a noninvasive, inexpensive, reliable method to evaluate peripheral vascular resistance in septic patients, and it is highly correlated with SVRI. In addition, SBRI can be used to evaluate peripheral circulatory disturbances in septic patients.

Abstract
BACKGROUND Febrile infections are an important cause of paediatric refractory status epilepticus, and immune-mediated mechanisms and inflammatory processes have been associated with neurological manifestations in such patients. The aim of this study was to investigate the effects of immunotherapy as adjuvant treatment for febrile refractory status epilepticus. METHODS We retrospectively reviewed cases of febrile refractory status epilepticus in a paediatric intensive care unit between January 2000 and December 2013 and analysed their clinical characteristics. Patients positive for antineuronal antibodies against surface antigens were excluded. RESULTS We enrolled 63 patients (38 boys), aged 1-18 years, all of whom received multiple antiepileptic drugs. Twenty-nine (46%) of the patients received intravenous immunoglobulin alone, 16 (25.4%) received a combination of intravenous immunoglobulin and methylprednisolone pulse therapy, and 18 (28.6%) did not receive immunotherapy treatment. Overall, 12 (19%) patients died within 1 month. After 6 months, 12 (20%) patients had good neurological outcomes, including two who returned to baseline and 13 (29.5%) who had favourable seizure outcomes. We compared the outcomes of the different treatments, and found that a combination of intravenous immunoglobulin and methylprednisolone pulse therapy had the best neurological and seizure outcomes at 6 months compared to intravenous immunoglobulin alone and no immunotherapy. CONCLUSIONS Our observational study showed that a combination of intravenous immunoglobulin and methylprednisolone pulse therapy as adjuvant treatment for febrile refractory status epilepticus was associated with better neurological and seizure outcomes. Further prospective studies are needed to confirm these findings.

Abstract
PURPOSE To report the clinical characteristics of abusive head trauma (AHT) in Taiwan and identify the risk factors associated with mortality of these patients. METHODS Children with clinically diagnosed AHT from January 1, 2000, to October 31, 2015 were reviewed. The demographic data, clinical features, and associated retinal and radiologic findings were analyzed. The multivariable logistic regression model analysis was performed to identify the risk factors associated with in-hospital mortality. RESULTS A total of 75 children were included. The mean age was 7.31 ± 6.57 months (range, 1-36 months). Retinal hemorrhages were detected in 69 children with AHT (92%). The majority of retinal hemorrhages were characterized by hemorrhagic numbers higher than ten (74.7%), multi-layered (54.7%), and extension beyond the posterior pole to the peripheral retina (73.3%). Twenty children (26.7%) had macular retinoschisis. As a direct result of AHT, ten children died in the hospital (13.3%). Logistic regression showed that respiratory distress or apnea (adjusted odds ratio [OR] = 22.46; 95% confidence interval [CI], 2.24-225.33; P = .0082), vomiting (adjusted OR = 11.94; 95% CI, 1.31-108.403; P = .0276), retinal finding of macular retinoschisis (adjusted OR = 8.9; 95% CI, 1.01-78.65; P = .0493), and the presence of subarachnoid hemorrhage (SAH) (adjusted OR = 15.17; 95% CI, 1.40-64.84; P = .0255) were independently associated with mortality. CONCLUSIONS Respiratory distress or apnea, vomiting, SAH, and macular retinoschisis are independently associated with mortality in abusive head trauma. A complete ophthalmologic examination with the immediate visualization of intraocular injury should be performed to clarify the likelihood of child abuse and predict a potential poor neurologic outcome.

Abstract
BACKGROUND Evidence for the beneficial effect of therapeutic burst-suppression coma in pediatric patients with febrile refractory status epilepticus is limited, and the clinical outcomes of this treatment strategy are largely unknown. Therefore, the aim of this study was to explore the outcomes of therapeutic burst-suppression coma in a series of children with febrile refractory status epilepticus. METHODS We retrospectively reviewed consecutive pediatric patients with febrile refractory status epilepticus admitted to our pediatric intensive care unit between January 2000 and December 2013. The clinical characteristics were analyzed. RESULTS Thirty-five patients (23 boys; age range: 1-18years) were enrolled, of whom 28 (80%) developed super-refractory status epilepticus. All of the patients received the continuous administration of intravenous antiepileptic drugs for febrile refractory status epilepticus, and 26 (74.3%) achieved therapeutic burst-suppression coma. All of the patients received mechanical ventilatory support, and 26 (74.3%) received inotropic agents. Eight (22.9%) patients died within 1month. The neurologically functional outcomes at 6months were good in six (27.3%) of the 22 survivors, of whom two returned to clinical baseline. The patients with therapeutic burst-suppression coma were significantly associated with hemodynamic support than the patients with electrographic seizures control (p=0.03), and had a trend of higher 1-month mortality rate, worse 6months outcomes, and a longer duration of hospitalization. CONCLUSIONS Our results suggest that therapeutic burst-suppression coma to treat febrile refractory status epilepticus may lead to an increased risk of hemodynamic instability and a trend of worse outcomes.

Evaluation of diaphragmatic function in mechanically ventilated children: An ultrasound study. PLoS One 2017; 12:e0183560. [PMID: 28829819 PMCID: PMC5567657 DOI: 10.1371/journal.pone.0183560] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2017] [Accepted: 08/07/2017] [Indexed: 11/23/2022] Open
Abstract
Background The recovery of diaphragmatic function is vital for successful extubation from mechanical ventilation. Recent studies have detected diaphragm atrophy in ventilated adults by using ultrasound, but no similar report has been conducted in children. In the current study, we hypothesized that mechanically ventilated children may also develop diaphragm atrophy and diaphragmatic dysfunction. Materials and methods Children who were admitted to the pediatric intensive care unit and were newly intubated for mechanical ventilation were enrolled into this prospective case–control study. Diaphragm ultrasound assessments were performed daily to evaluate diaphragmatic function in the enrolled children until their discharge from the pediatric intensive care unit. Diaphragm thickness and the diaphragmatic thickening fraction (DTF) were measured through these assessments. Results A total of 31 patients were enrolled, and overall, 1389 ultrasound assessments were performed. Immediately after intubation, the initial diaphragm thickness and DTF were measured to be 1.94 ± 0.44 mm and 25.85% ± 3.29%, respectively. In the first 24 hours of mechanical ventilation, diaphragm thickness and the DTF decreased substantially and decreased gradually thereafter. After extubation, the DTF was significantly different between the successful and failed extubation groups (P < 0.001), and a DTF value of <17% was associated with extubation failure. Conclusions Diaphragm ultrasound is a noninvasive method for measuring diaphragmatic function in mechanically ventilated children. In this study, significant diaphragm atrophy and a decreased DTF were observed within 24 hours of mechanical ventilation. The recovery of diaphragm thickness and the DTF may be a potential predictor of successful extubation from mechanical ventilation.

Abstract
Background Endothelial dysfunction plays an important role in the pathophysiology of sepsis. As previously reported, the serum thrombomodulin is elevated in diseases associated with endothelial injury. Objective The aim of this study was to investigate the association of serum thrombomodulin level in different pediatric sepsis syndromes and evaluate the relationship with disease severity and mortality. Methods We prospectively collected cases of sepsis treated in a pediatric intensive care unit from June 2012 to July 2015 at Chang Gung Children’s Hospital in Taoyuan, Taiwan. Clinical characteristics and serum thrombomodulin levels were analyzed. Results Increased serum thrombomodulin levels on days 1 and 3 of the diagnosis of sepsis were found in different pediatric sepsis syndromes. Patients with septic shock had significantly increased serum thrombomodulin levels on days 1 and 3 [day 1: median, 6.9 mU/ml (interquartile range (IQR): 5.8–12.8) and day 3: median, 5.8 mU/ml (IQR: 4.6–10.8)] compared to healthy controls [median, 3.4 mU/ml (IQR: 2.3–4.2)] (p = <0.001 and 0.001, respectively) and those with sepsis [day 1: median, 2.9 mU/ml (IQR: 1.8–4.7) and day 3: median, 3 mU/ml (IQR: 1.5–3.5)] and severe sepsis [day 1: median, 3.3 mU/ml (IQR: 1.3–8.6) and day 3: median, 4.4 mU/ml (IQR: 0.5–6)] (p = <0.001 and 0.001, respectively). There was also a significant positive correlation between serum thrombomodulin level on day 1 and day 1 PRISM-II, PELOD, P-MOD and DIC scores. The patients who died had significantly higher serum thrombomodulin levels on days 1 and 3 [day 1: median, 9.9 mU/ml (IQR: 6.2–15.6) and day 3: median, 10.4 mU/ml (IQR: 9.2–11.7)] than the survivors [day 1; median, 4.4 mU/ml (IQR: 2.2–7.5) and day 3: [median, 3.5 mU/ml (IQR: 1.6–5.7)] (p = 0.046 and 0.012, respectively). Conclusion Increased serum thrombomodulin levels were found in different pediatric sepsis syndromes and correlated with disease severity and mortality.

Abstract
Children with abuse who are admitted to the intensive care unit (ICU) may have high mortality and morbidity and commonly require critical care immediately. It is important to understand the epidemiology and clinical characteristics of these critical cases of child maltreatment.We retrospectively evaluated the data for 355 children with maltreatments admitted to the ICU between 2001 and 2015. Clinical factors were analyzed and compared between the abuse and the neglect groups, including age, gender, season of admission, identifying settings, injury severity score (ISS), etiologies, length of stay (LOS) in the ICU, clinical outcomes, and mortality. In addition, neurologic assessments were conducted with the Pediatric Cerebral Performance Category (PCPC) scale.The most common type of child maltreatments was neglect (n = 259), followed by physical abuse (n = 96). The mean age of the abuse group was less than that of the neglect group (P < .05). Infants accounted for the majority of the abuse group, and the most common etiology of abuse was injury of the central nervous system (CNS). In the neglect group, most were of the preschool age and the most common etiologies of abuse were injury of the CNS and musculoskeletal system (P < .001). The mortality rate in the ICU was 9.86%. The ISS was significantly associated with mortality in both the 2 groups (both P < .05), whereas the LOS in the ICU and injuries of the CNS, musculoskeletal system, and respiratory system were all associated with mortality in the neglect group (all P < .05). The PCPC scale showed poor prognosis in the abuse group as compared to the neglect group (P < .01).In the ICU, children in the abuse group had younger age, higher ISS, and worse neurologic outcome than those in the neglect group. The ISS was a predictor for mortality in the abuse and neglect groups but the LOS in the ICUs, injuries of the CNS, musculoskeletal system, and respiratory system were indicators for mortality in the neglect group. Most importantly, identifying the epidemiological information may provide further strategies to reduce the harm, lower the medical costs, and improve clinical care quality and outcomes in children with abuse.

Abstract
Child abuse includes all forms of physical and emotional ill treatment, sexual abuse, neglect, and exploitation that results in actual or potential harm to the child's health, development, or dignity. In Taiwan, the Child Protection Medical Service Demonstration Center (CPMSDC) was established to protect children from abuse and neglect. We further analyzed and compared the trends and clinical characteristics of cases reported by CPMSDC to evaluate the function of CPMSDC in approaching child abuse and neglect in Taiwan. We prospectively recorded children with reported child abuse and neglect in a CPMSDC in a tertiary medical center from 2014 to 2015. Furthermore, we analyzed and compared age, gender, scene, identifying settings, time of visits, injury type, injury severity, hospital admission, hospitalization duration, and outcomes based on the different types of abuse and the different settings in which the abuse or neglect were identified. Of 361 child abuse cases (mean age 4.8 ± 5.36 years), the incidence was highest in 1- to 6-year-old children (n = 198, 54.85%). Physical abuse and neglect were predominant in males, while sexual abuse was predominant in females (P < 0.001). Neglect was most common (n = 279, 75.85%), followed by physical (n = 56, 15.51%) and sexual abuse (n = 26, 7.2%). The most common identifying setting was the emergency department (n = 320, 88.64%), with neglect being most commonly reported. Head, neck, and facial injuries were more common in physically abused children than in neglected and sexual abused children (P < 0.005), leading to longer hospitalization (P = 0.042) and a higher Injury Severity Score (P = 0.043). There were more skin injuries in neglect (P < 0.001). The mortality rate was 2.49% (n = 9). The CPMSDC could enhance the ability, alertness, and inclination of professionals to identify suspected cases of child abuse, and to increase the rate of registry. Cases of physical abuse had a higher Injury Severity Score, longer duration of hospitalization, and more injuries of head, face, and neck compared with other types of abuse. The reported rate of neglect was highly elevated after the CPMSDC established during the study period. Recognition of neglect is not easy, but the consequent injury, especially asphyxia, may lead to mortality.

Abstract
A 15-year-old boy presented with airway obstruction and a history of sore throat and progressive dyspnoea for 1 month. A lateral neck radiograph showed an enlarged epiglottis, and a neck computed tomography (CT) demonstrated a cyst attached to the lingual surface of the epiglottis. A large epiglottic cyst, 4 cm in length, was removed surgically. Epiglottic cysts have been reported to cause airway obstruction in neonates, infants and adults, but, to the best of our knowledge, it has rarely been reported in adolescents.

Analysis of Fulminant Cerebral Edema in Acute Pediatric Encephalitis. Pediatr Neonatol 2016; 57:402-407. [PMID: 26852357 DOI: 10.1016/j.pedneo.2015.11.002] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2015] [Revised: 10/30/2015] [Accepted: 11/14/2015] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Acute pediatric encephalitis with fulminant cerebral edema can rapidly become fatal or result in devastating neurological sequelae. METHODS All cases coded with the discharge diagnosis of acute encephalitis between January 2000 and December 2010 were reviewed. Of the 1038 children with acute pediatric encephalitis, 25 were enrolled in our study with ages ranging from 5 months to 16 years. RESULTS The major neurological symptoms included an altered level of consciousness (72%), vomiting (60%), and headache (48%). The onset of neurological symptoms to signs of brain herniation ranged from 0 days to 9 days. Nineteen (76%) patients had a seizure 24-48 hours prior to showing signs of fulminant cerebral edema, and 12 (48%) patients developed status epilepticus. Sixteen patients died, and no survivors returned to baseline. Risk factors for seizures and status epilepticus were compared between the fulminant cerebral edema group (n = 25, 19 seizures, including 12 status epilepticus) and control group (nonfulminant cerebral edema) (n = 1013, 444 seizures, including 141 status epilepticus; p = 0.001 for seizures and p < 0.001 for status epilepticus). CONCLUSION Our findings indicate that preceding seizures and status epilepticus are significant risk factors for fulminant cerebral edema in children with acute encephalitis.

Comparisons between Full-time and Part-time Pediatric Emergency Physicians in Pediatric Emergency Department. Pediatr Neonatol 2016; 57:371-377. [PMID: 27178642 DOI: 10.1016/j.pedneo.2015.10.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2015] [Revised: 08/31/2015] [Accepted: 10/30/2015] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Pediatric emergency medicine is a young field that has established itself in recent decades. Many unanswered questions remain regarding how to deliver better pediatric emergency care. The implementation of full-time pediatric emergency physicians is a quality improvement strategy for child care in Taiwan. The aim of this study is to evaluate the quality of care under different physician coverage models in the pediatric emergency department (ED). METHODS The medical records of 132,398 patients visiting the pediatric ED of a tertiary care university hospital during January 2004 to December 2006 were retrospectively reviewed. Full-time pediatric emergency physicians are the group specializing in the pediatric emergency medicine, and they only work in the pediatric ED. Part-time pediatricians specializing in other subspecialties also can work an extra shift in the pediatric ED, with the majority working in their inpatient and outpatient services. We compared quality performance indicators, including: mortality rate, the 72-hour return visit rate, length of stay, admission rate, and the rate of being kept for observation between full-time and part-time pediatric emergency physicians. RESULTS An average of 3678 ± 125 [mean ± standard error (SE)] visits per month (with a range of 2487-6646) were observed. The trends in quality of care, observed monthly, indicated that the 72-hour return rate was 2-6% and length of stay in the ED decreased from 11.5 hours to 3.2 hours over the study period. The annual mortality rate within 48 hours of admission to the ED increased from 0.04% to 0.05% and then decreased to 0.02%, and the overall mortality rate dropped from 0.13% to 0.07%. Multivariate analyses indicated that there was no change in the 72-hour return visit rate for full-time pediatric emergency physicians; they were more likely to admit and keep patients for observation [odds ratio = 1.43 and odds ratio = 1.71, respectively], and these results were similar to those of senior physicians. CONCLUSION Full-time pediatric emergency physicians in the pediatric ED decreased the mortality rate and length of stay in the ED, but had no change in the 72-hour return visit rate. This pilot study shows that the quality of care in pediatric ED after the implementation of full-time pediatric emergency physicians needs further evaluation.
