The aim was to evaluate if the addition of video discharge instructions (VDIs) to usual verbal information improved the comprehension of information provided to caregivers of patients who consult for acute gastroenteritis (AGE). We conducted an open-label, parallel, randomized trial, enrolling patients who consulted for AGE at a tertiary hospital. First, caregivers answered a written test concerning AGE characteristics and management. They were randomly allocated to a control group, which received the usual verbal instructions, or to an intervention group, which additionally received VDI. After discharge, caregivers were contacted by telephone and answered the same test, satisfaction questions, and follow-up information. From September 2019 to March 2020, 139 patients were randomized, 118 completed follow-up. The mean score was 3.13 (SD 1.07) over 5 points in the initial test and 3.96 (SD 0.96) in the follow-up test. Patients in the intervention group had a greater improvement (1.17 points, SD 1.11) than those in the control group (0.47 points, SD 0.94, p < 0.001). In the follow-up test, 49.1% in the intervention group and 18.6% in the control group answered all questions correctly (p < 0.001). There were no significant differences in return visits. Caregivers gave high satisfaction scores regardless of the allocation group. Conclusion: Video instructions improve caregivers' understanding of discharge information. Trial registration: [NCT04463355, retrospectively registered July 9, 2020]. What is Known: • Poor comprehension of discharge instructions leads to incorrect treatment after discharge, increased readmissions and a reduction of caregivers' satisfaction. • Video discharge instructions are useful providing concise information independently of the patients' health literacy level or communication skills of the health care provider What is New: • The addition of video discharge instructions to verbal instructions improves caregivers' knowledge about AGE improved with respect to those who only receive verbal instructions • Video instructions do not add extra time to the emergency department visits

Objectives:The objective of this study was to compare the risk of contamination for urine samples collected from patients younger than 90 days using 2 different techniques: bladder stimulation and "clean catch" (CC) and urinary catheterization (CATH).Methods: A case-control study was carried out in the pediatric emergency room of a tertiary hospital between January 2016 and September 2017. All urine samples collected from patients younger than 90 days by CC or CATH were included. The incidence of contaminated urine samples was compared for both methods, and the risk of contamination was estimated using univariate and multivariate analyses.Results: A total of 473 urine samples were collected, 310 via CATH (65.5%) and 163 via CC (34.5%). The median age was 1.4 months (interquartile range, 0.8-2.1 months), and 54.1% were males. Seventeen patients had a history of urinary tract infection (3.6%), and 16 were diagnosed with a congenital urorenal anomaly (3.4%). Sixteen urine samples were found to be contaminated (3.4%): 5 collected via CATH (1.6%) and 11 via CC (6.8%). The univariate analysis revealed a greater risk of contamination in specimens obtained using CC versus CATH (odds ratio, 4.41; 95% confidence interval, 1.51-12.93), and the multivariate analysis confirmed CC collection as an independent risk factor for contamination (odds ratio, 5.61; 95% confidence interval, 1. 83-17.19). Conclusions:The number of contaminated urine samples in infants younger than 90 days in our pediatric emergency department is low. However, using the CC urine collection technique seems to be an independent risk factor for sample contamination.

Aim: Acute Epstein-Barr virus (aEBV) and cytomegalovirus (CMV) infections frequently have similar manifestations. We aim to evaluate the characteristics of aEBV infection, risk factors for hospitalisation and differences according to CMV IgM detection (EBV-CMV co-detection) in children. Methods:Retrospective, single-centre study including patients <16 years diagnosed with aEBV infection (positive anti-EBV IgM/Paul-Bunnell test and acute symptomatology). EBV-CMV co-detection was defined as positive CMV IgM. Factors associated with age, hospitalisation and EBV-CMV co-detection were analysed in a multivariate analysis.Results: A total of 149 patients were included (median age 4.6 years). Most frequent manifestations were fever (77%), cervical lymphadenopathy (64%) and elevated liver enzymes (54%). Younger children had lower rate of positive Paul-Bunnell test (35% vs. 87%; p < 0.01), but higher rate of EBV-CMV co-detection (54% vs. 29%; p = 0.03). These children tended to have less typical symptoms of infectious mononucleosis and higher hospitalisation rate. The overall antibiotic prescription was 49%. Hospitalisation (27 children; 18%) was independently associated with prior antibiotic therapy and anaemia. Sixty-two cases (42%) had EBV-CMV co-detection, which was independently associated with elevated liver enzymes and younger age. Conclusion:In this study, younger children with aEBV infection presented more frequently with atypical clinical symptoms, had higher EBV-CMV co-detection rates and were more often hospitalised. Hospitalisation was associated with prior antibiotic prescription.
