The article discusses a study which assessed whether paediatric residents and paediatricians in Spain follow recommendations for the lumbar puncture (LP) technique.

Background: Salmonella spp. is an uncommon microorganism in bloodstream infections among pediatric patients in our setting, although in developing countries it is the most common causative organism in blood cultures., Methods: We describe the children presenting to pediatric emergency departments and diagnosed with Salmonella bacteremia (SB) and identify clinical and laboratory predictors of poor outcome (ie, complications, sequelae and death) by bivariate analysis. We performed an observational study and subanalysis of a multicenter prospective registry, including patients <18 years of age with a positive blood culture obtained at any of the 22 participating Spanish pediatric emergency departments between 2011 and 2016. We considered young age, chronic diseases, immunosuppressive treatment and intestinal flora disruption as risk factors for SB., Results: Of the 55 patients with SB (3.2% of registered bacteremia), 32 (58.2%) had no risk factors for SB, 42 (76.3%) had a normal pediatric assessment triangle and 45 (81.8%) an associated gastrointestinal infection (acute gastroenteritis or enteric fever). Nine (16.4%) had a poor outcome, including 1 death (1.8%). A poor outcome was more common in patients with an abnormal pediatric assessment triangle [odds ratio (OR): 51.6; 95% confidence interval (CI): 9.2-289.5], an altered physical examination (OR: 15.2; 95% CI: 4.4-58.8) and elevated C-reactive protein (OR: 1.01; 95% CI: 1.005-1.03)., Conclusions: Most SBs were related to a gastrointestinal infection. One in 6 children had a poor outcome; abnormal pediatric assessment triangle on arrival (25% of patients) was the main risk factor identified., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Stridor is a clinical sign of an underlying disease and a common reason for pediatric emergency department (PED) consultation. Patients presenting with stridor must be evaluated to determine the origin of this abnormality. We present the case of a 7-year-old female patient who presented to our Pediatric Emergency Department with a history of recurrent episodes of stridor with increasing frequency over the previous 4 years, for this reason she was previously admitted to the pediatric intensive care unit. Findings from the otorhinolaryngologic assessment with flexible fiber-optic endoscopy led to a diagnosis of congenital synechia of the vocal cords. The cervical CT scan evidenced critical stenosis of the airway. An initial cordectomy and placement of a silicone device for fixation were performed. Subsequently, the patient required 6 additional interventions for progressive dilation of the glottic space at the level of the vocal cords and injections of mitomycin C injections (an antineoplastic that inhibits collagen proliferation). This case highlights the importance of additional studies (especially examination of the upper airway) when atypical or recurrent findings are revealed by the clinical history, physical examination, or disease course in patients with croup to prioritize cases severe enough to require pediatric intensive care unit admission., (Copyright © 2023 National Association of Pediatric Nurse Practitioners.

Background: Staphylococcus aureus has become the leading cause of bacteremia among previously healthy children older than 5 years., Methods: We aimed to describe the infants presenting to pediatric emergency departments and diagnosed with S. aureus bacteremia (SAB) and identify predictors (clinical and laboratory variables) of poor outcome (complications, sequelae or death). We performed an observational study and subanalysis of a multicenter prospective registry, including every patient under the age of 18 years with a positive blood culture obtained at any of the 22 participating Spanish pediatric emergency departments between 2011 and 2016. We considered chronic diseases, immunosuppressive treatment and the presence of mechanical devices as risk factors for SAB., Results: Of the 229 patients with SAB, 176 (76.9%) were previously healthy, 192 (83.8%) had a normal pediatric assessment triangle and 158 (69.0%) had an associated focal infection (mainly osteoarticular infection, skin and soft tissue infection and pneumonia). Fifty-three patients (23.1%) had 1 or more risk factors for SAB. Thirty-one (13.5%) presented a poor outcome, including 4 deaths (1.7%). A poor outcome was more common in patients with SAB risk factors [odds ratio (OR): 7.0; 95% CI: 3.2-15.4], abnormal PAT (OR: 5.9; 95% CI: 2.6-13.3), elevated procalcitonin (OR: 1.2; 95% CI: 1.05-1.3) and C-reactive protein, the latter being the only independent predictor of poor outcome (OR: 1.01; 95% CI: 1.01-1.02)., Conclusions: Overall, children with SAB are previously healthy, appear well, and have an associated focal infection. One of 7 had a poor outcome, with C-reactive protein being the only predictor identified., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Introduction: Staphylococcus aureus is a common germ in bacterial infections in children. The rate of methicillin-resistant S. aureus (MRSA) is increasing lately., Objectives: The main aim is to know the rate of positive cultures to MRSA in Spanish pediatric emergency departments. The secondary aims are to analyse the risk factors for MRSA isolation (patient origin, history of hospitalization or surgery in the previous 90 days, antibiotherapy in the previous 60 days, presence of comorbidity, invasive devices, prior MRSA isolation) and to analyse the morbidity of these infections., Methodology: Retrospective multicenter study (07/01/2017-06/30/2018) with review of patient histories with isolation of S. aureus in samples of any origin obtained in 8 pediatric emergency departments of the Infectious Diseases Working Group of the Spanish Society of pediatric Emergencies., Results: During this period, S. aureus was detected in 403 patients (average age 75.8 ± 59.2 months; 54.8% male): 28.8% hospital-related infections (HRI) and 71.2% community-related infections (CRI). Overall, MRSA rate was 16.6% (95% CI: 13-20.2%); 18.1% in HRI and 16.2% in CRI (p > 0.05). The highest rates of MRSA were obtained in skin abscesses (29.3%, CI 95%: 21.8-36.8%), patients not born in Spain (52%; CI 95%: 32-72%) or patients with a previous MRSA infection (90%; CI 95% 71.4-100%). 167 (41%) patients were admitted, 12 (3%) had complications and 4 (1%) suffered sequels. There were no deaths., Conclusions: The overall MRSA rate was one in 6 staphylococcal infections. Higher MRSA rates were detected in samples of suppurating skin injuries and in foreign children or in children with a history of previous MRSA infection. In suppurative skin lesions, early drainage is essential and the change to an antibiotic with MRSA coverage should be considered if the evolution is inadequate., (Copyright © 2021 Asociación Española de Pediatría.

Introduction: The prevalence and the variability of clinical practice in acute bronchiolitis make it a perfect candidate to monitor the proper use of resources. The aim of this study is to analyse the differences in the use of non-recommended resources in the management of bronchiolitis in the Emergency Department, before and after the establishment of a new protocol., Methods: A retrospective study was conducted on a sample of patients diagnosed with acute bronchiolitis in the Emergency Department of a tertiary hospital, before (December 2014) and after (December 2016) the implementation of a new protocol. A comparison was made on the use of diagnostic tests and treatments in both groups., Results: The analysis included a total of 113 patients with acute bronchiolitis examined in December 2014, and 128 patients in December 2016. The clinical characteristics in both groups were similar. In the post-protocol period, there was a significant decrease in the use of salbutamol, both in the Emergency Department (33.6% vs 19.5%, P<.01) and at discharge (46.7% vs 15.2%, P<.001); adrenaline (12.4% vs 2.4%, P=.002), and nebulised hypertonic saline solution (5.3% vs 0.8%, P=.04). Rapid respiratory syncytial virus (RSV) testing was also decreased (40.7% vs 26.6%, P=.01). This decrease was not associated with an increase in the number of admissions or re-assessments in the Emergency Department., Conclusions: The establishment of a new protocol for acute bronchiolitis decreased the use of non-recommended resources, mainly the use of bronchodilators and rapid RSV testing., (Copyright © 2017 Asociación Española de Pediatría.

Introduction: Lumbar puncture (LP) is a commonly performed procedure in paediatrics. Performing this technique properly can avoid the most common associated complications., Objective: To assess whether paediatricians and paediatric residents in Spain follow current recommendations for the LP technique., Material and Methods: A cross-sectional study was conducted by sending a questionnaire by mail through the Spanish Society of Paediatric Emergencies, collecting demographic information and responses to multiple choice questions about LP technique., Results: A total of 206 questionnaires were analysed, of which 143 (69.5%) were answered by paediatricians, and 63 (30.5%) by paediatric residents. The majority (128; 62.1%) of physicians did not allow parents to be present during LP, 198 (96.1%) routinely use analgesia and sedation; 84 (42%) only used local anaesthesia. The majority of respondents used standard Quincke needles (126; 62.7%). The bevel was correctly positioned when puncturing the dura mater by 22 residents (36.1%) and 21 paediatricians (15.1%), a variation that was statistically significant (P=.001). For neonatal lumbar punctures, 63 paediatricians (46%) and 19 paediatric residents used a butterfly needle which did not contain a stylet, and this difference was also statistically significant (P=.035). Of those surveyed, 190 (92.2%) re-inserted the stylet when re-orientating the needle, and 186 (93%) re-oriented this when removing it. The recommendation of bed rest was made by 195 (94.7%) physicians., Conclusions: The majority of paediatricians orient the bevel wrongly when inserting the needle during LP, and still use "butterfly" needles in newborns, despite warnings to the contrary. Paediatric residents and less experienced paediatricians follow the recommendations more frequently., (Copyright © 2011 Asociación Española de Pediatría. Published by Elsevier Espana.

Introduction: Bladder catheterization (BC) is frequently performed to diagnose urinary tract infection (UTI) (the most common serious bacterial infection among young children). The purposes of this study were to evaluate performance and complications of BC to obtain a urine specimen., Material and Methods: This was a prospective study conducted in an urban children's hospital on patients who had a urine specimen obtained in the emergency department (ED) by BC between November 1, 2009 and December 15, 2009. Epidemiological data and the medical reasons why the BC was performed were reviewed. Finally, to determine the complications we contacted the family by telephone at least one month after the BC., Results: A total of 126 BC were performed in 124 patients, 45 males (35.7%) and 81 female (64.3%). A urine sample was obtained in all cases. The median age was 7 months (5 days-35 months). Of the 126 urine cultures collected, 34 were positive (26.98%) and 1 was considered contaminated (0.8%). Escherichia coli was the most common pathogen (27, 79.41%). Fever (76.2%) was the main reason why BC was performed in children. Of the 116 patients contacted by telephone, only 5 mentioned complications: genital pain (3), unconfirmed hematuria (1) and UTI 12 days after (1)., Conclusions: BC performed in ED to obtain a urine sample in non toilet-trained children is effective and safe. BC is an invasive method which needs to be quality controlled., (Copyright © 2011 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.)

We evaluated the clinical presentation and prognosis of three children with acute glomerulonephritis (AGN) associated with pneumonia. The patient database of Niño Jesús Children's Hospital was analyzed retrospectively (1996-2007) for patients diagnosed at discharge with both pneumonia and AGN. Those with recent pharyngeal or cutaneous infection were excluded. Three patients (1.67, 4.25, and 5 years old, respectively) were selected. All of them had lobar pneumonia, developing both macrohematuria and proteinuria within 24 h after admission. Decreased glomerular filtration rate was found in one patient. Two children developed arterial hypertension and one a slight pleural effusion. Two children had low C3 levels, and one had both low C3 and C4 levels. A Streptococcus pneumoniae serotype 17F was isolated from the blood culture of one patient. On follow-up, all patients had normal blood pressure and renal function with microhematuria persisting long term. Our patients with pneumonia-associated AGN had a good prognosis for both pulmonary and renal involvement.

Background: Many studies have been performed to establish criteria for the differential diagnosis between bacterial and viral meningitis. In 1980, Thome and Boyer proposed a score that has been widely used., Objectives: The aim of this study was to assess the utility of this score when applied to our patients with meningitis and to evaluate the diagnostic yield after adding other laboratory tests., Methods: We retrospectively studied the children diagnosed with meningitis in the Hospital Niño Jesús between January 1993 and February 2000. In all patients, Boyer's score and the following laboratory variables were applied: reactive C protein levels, percentage of neutrophils in the cerebrospinal fluid depending on age, and the ratio of immature cells/total neutrophils in the blood. We calculated the sensitivity and specificity of Boyer's score and the laboratory variables., Results: Of the 476 children with meningitis, 402 had viral meningitis and 74 had bacterial meningitis. All the children with bacterial meningitis except seven had a score higher than 3 (a doubtful indication for antibiotic treatment). The sensitivity and specificity of Boyer's score was 90 % and 99 % respectively. When laboratory variables were added, sensitivity was 100 % and specificity was 98 %., Conclusions: Boyer's score is a useful tool for the differential diagnosis of meningitis, but its diagnostic yield is considerably increased when the results of laboratory tests are added.
