BACKGROUND AND OBJECTIVES: In the 2023--2024 respiratory syncytial virus (RSV) season, Spain became one of the first countries to introduce universal RSV prophylaxis, during which all infants born at this time were eligible to receive nirsevimab. Locally, most Spanish regions also immunized infants younger than age 6 months at the start of the season (extended catch-up). The aim of this study was to assess how RSV prophylaxis affected the number of infants presenting to pediatric emergency departments with acute respiratory infections. METHODS: A retrospective study was conducted in 15 Spanish pediatric emergency departments from 9 different regions between the 2018 and 2024 epidemic seasons (November-January). We compared the seasons occurring in 2018-2023 and the 2023-2024 season regarding the number of episodes of lower respiratory tract infection and acute bronchiolitis, acute bronchiolitis- related hospital admissions, and PICU admissions. RESULTS: A comparison with the average rates for the previous epidemic seasons revealed a 57.7% decrease in episodes of lower respiratory tract infection in 2023-2024 (95% CI, 56.5-58.8; P < .001; range among hospitals, 4.8-82.8), a 59.2% decrease in episodes of acute bronchiolitis (95% CI, 57.9-60.4; P < .001; range, 6.9-84.1), a 63.1% reduction in acute bronchiolitis- related hospital admissions (95% CI, 60.9-65.2; P < .001; range, 31.4-86.8), and a 63.1% reduction in PICU admissions (95% CI, 58.1-67.9; P < .001; range, 18.2-81.8). Hospitals in regions applying extended catch-up showed better results. CONCLUSIONS: Nirsevimab can protect a broad infant population against RSV infection with high effectiveness. Approaches including extended catch-up are the most effective, although costeffectiveness must be considered. [ABSTRACT FROM AUTHOR]

Background: In adult population with community acquired pneumonia high levels of pro-adrenomedullin (pro-ADM) have been shown to be predictors of worse prognosis. The role of this biomarker in pediatric patients had not been analyzed to date. The objective of this study is to know the levels of pro-ADM in children with community acquired pneumonia (CAP) and analyze the relation between these levels and the patients' prognosis. Findings: Prospective observational study including patients attended in the emergency service (January to October 2009) admitted to hospital with CAP and no complications at admission. The values for pro-ADM were analyzed in relation to: need for oxygen therapy, duration of oxygen therapy, fever and antibiotic therapy, complications, admission to the intensive care unit, and length of hospital stay. Fifty patients were included. Ten presented complications (7 pleural effusion). The median level of pro-ADM was 1.0065 nmol/L (range 0.3715 to 7.2840 nmol/L). The patients presenting complications had higher levels of pro-ADM (2.3190 vs. 1.1758 nmol/L, p = 0.013). Specifically, the presence of pleural effusion was associated with higher levels of pro-ADM (2.9440 vs. 1.1373 nmol/L, p<0.001).Conclusions: In our sample of patients admitted to hospital with CAP, pro-ADM levels are related to the development of complications during hospitalization [ABSTRACT FROM AUTHOR]

Objectives: To determine the degree of compliance with health care quality criteria in the treatment of patients with lower airway obstruction in Spanish pediatric emergency departments (PEDs), to explore the reasons for noncompliance, and to make recommendations for improvement., Material and Methods: We carried out a retrospective, cross-sectional study of a series of patients under the age of 14 years to determine the degree of compliance with 5 quality indicators. The patients were attended in 22 PEDs on days 1 and 15 of each month in 2013. We also distributed a questionnaire to chiefs of department to discover possible reasons for noncompliance. Finally, a group of experts followed a process to produce consensus-based recommendations to improve quality of care through compliance with the indicators., Results: We included 2935 patients with a median (interquartile range) age of 2.8 (1.4-5.1) years. The overall rates of compliance were 39.8% for assessment of severity, 0.1% for measurement of peak flow, 64.4% for delay in attending a patient with severe shortness of breath, 59.1% for checking oxygen saturation and respiratory frequency, and 34.3% for treatment with inhalers and a spacer. The most common reasons for noncompliance were lack of time or material and the absence of the recommendation in protocols. The following improvement steps were recommended: reassess the usefulness of peak flow measurement in PEDs, reformulate the criteria for delay in attending patients with severe dyspnea, and adopt new indicators and templates that facilitate the recording of vital constants and scores on severity scales., Conclusion: An acceptable level of compliance was not achieved on any of the health care quality indicators for a variety of reasons. A series of steps should be taken to improve compliance.

Introduction: Atypical febrile seizures (AFS) have been related with a higher incidence of severe pathologies of the central nervous system (CNS). Recent studies show a reduction in the prevalence of some of these diseases, a fact that could affect their management. AIMS. To determine the prevalence of severe pathologies of the CNS in patients treated for AFS in A and E departments and to detect any differences between these and patients suffering from AFS that is not associated to any severe pathology., Patients and Methods: A retrospective study was conducted by reviewing the medical records of patients diagnosed with AFS between November 2008 and November 2011., Results: Altogether, the sample consisted of 231 episodes of AFS (223 patients), with an average age of 1.7 years (p25-75=1.2-2.3 years), 133 (57.6%) of whom were males. Twelve patients (5.2%; 95% CI=2.7-8.9) were diagnosed with a severe pathology of the CNS. In patients with a severe pathology of the CNS, AFS is on most occasions the first episode (91.7% versus 63%; p=0.036) and more than one diagnostic criterion is present (50% versus 15.1%; p=0.007). Moreover, focal seizures (50% versus 12.8%; p=0.003) or epileptic status (25% versus 5.9%; p=0.041) are more common, and patients present altered levels of awareness that persist after the episode (66.7% versus 31.5%; p=0.002)., Conclusions: Given the fact that the prevalence of severe pathology of the CNS in patients with AFS is low, carrying out complementary tests or admission to hospital on a routine basis are not recommended. Certain characteristics of the episode increase the likelihood of AFS being the manifestation of a severe pathology of the CNS (being a first episode, presenting more than one diagnostic criterion for AFS and being a focal seizure or epileptic status), and should therefore be taken into account in the management of the patient.

Background: The value of neuroimaging in predicting unfavorable events in the outcome of pediatric patients has not been established. Our objectives were to determine clinical characteristics and outcome of severely head-injured children admitted to the pediatric intensive care unit (PICU) of a pediatric third-level university hospital and to evaluate the use of neuroimaging as a prognostic factor of morbimortality in these patients., Methods: We performed a 9-year retrospective review. We included all patients with severe head injury admitted to the pediatric intensive care unit of our hospital from January 1995 to December 2003 requiring invasive intracranial pressure monitoring. Clinical summaries and imaging studies were reviewed., Results: Data for 156 pediatric patients, aged 1 to 18 years, were collected. We reclassified neuroimaging patterns into 2 groups: those with few imaging findings and those with important lesions. These 2 groups were significantly correlated with initial Glasgow Coma Scale (P < .05). We classified patients into favorable evolution, moderate disability, and unfavorable evolution. Poorer evolution correlated with poorer initial neuroimaging patterns, and these differences were statistically significant (P < .05)., Conclusions: In our group of patients, initial Glasgow Coma Scale was related with the initial neuroimaging pattern, and this relation was statistically significant. Findings in the first and second neuroimaging were useful as prognostic factors in our series.

Object: The authors evaluated the initial intracranial pressure (ICP) and cerebral perfusion pressure (CPP) as prognostic factors in severe head injury in children and tried to determine the optimal CPP range., Methods: The authors performed a 9-year retrospective review of all patients with severe traumatic brain injuries (TBIs) who required invasive ICP monitoring and were admitted to the pediatric intensive care unit at their institution between January 1995 and December 2003. These patients had Glasgow Coma Scale scores lower than 8 and/or required ICP monitoring due to worsening neurological status or neuroimaging results suggestive of cerebral hypertension. Clinical summaries and imaging studies were reviewed. Data for 156 pediatric patients who ranged in age from 1 to 18 years were obtained. Half of these patients presented with normal initial ICPs (< 20 mm Hg), and a good outcome was achieved in 80% of these children. An unfavorable outcome was observed in more than 60% of patients with an initial CPP lower than 40 mm Hg. The proportion of patients with an unfavorable outcome decreased to 10% with initial CPPs higher than 60 mm Hg, but patients with initial CPPs higher than 70 mm Hg did not improve., Conclusions: Initial ICP and CPP measurements were useful as prognostic factors in pediatric patients with severe TBIs: patients with initial CPPs between 40 and 70 mm Hg were found to have a better neurological prognosis than those with CPPs either higher or lower than that range.
