Endobronchial and endotracheal tumours are rare in the paediatric population, especially in neonates. The common presentation is respiratory distress with persistent lung collapse or hyperinflation. Treatment usually involves endoscopic or surgical lobar resection. This case presents a preterm neonate who developed acute respiratory distress with persistent right upper lobe atelectasis. A flexible bronchoscopy showed a pediculate violaceous endobronchial lesion in the right main bronchus. Endoscopic resection was not possible due to the patient's low weight and the decision was made to support the patient with continuous positive airway pressure (CPAP) at home, while monitoring her closely. Remarkably, the lesion spontaneously resolved, and CPAP support was discontinued successfully. The case emphasises the importance of early bronchoscopy, continuous monitoring and the possibility of using CPAP support until conditions are reunited for an eventual resection. This unique case also demonstrates the potential for spontaneous resolution in some cases., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Respiratory syncytial virus (RSV) is the most common cause of acute lower respiratory infection in young children. We previously estimated that in 2015, 33·1 million episodes of RSV-associated acute lower respiratory infection occurred in children aged 0-60 months, resulting in a total of 118 200 deaths worldwide. Since then, several community surveillance studies have been done to obtain a more precise estimation of RSV associated community deaths. We aimed to update RSV-associated acute lower respiratory infection morbidity and mortality at global, regional, and national levels in children aged 0-60 months for 2019, with focus on overall mortality and narrower infant age groups that are targeted by RSV prophylactics in development., Methods: In this systematic analysis, we expanded our global RSV disease burden dataset by obtaining new data from an updated search for papers published between Jan 1, 2017, and Dec 31, 2020, from MEDLINE, Embase, Global Health, CINAHL, Web of Science, LILACS, OpenGrey, CNKI, Wanfang, and ChongqingVIP. We also included unpublished data from RSV GEN collaborators. Eligible studies reported data for children aged 0-60 months with RSV as primary infection with acute lower respiratory infection in community settings, or acute lower respiratory infection necessitating hospital admission; reported data for at least 12 consecutive months, except for in-hospital case fatality ratio (CFR) or for where RSV seasonality is well-defined; and reported incidence rate, hospital admission rate, RSV positive proportion in acute lower respiratory infection hospital admission, or in-hospital CFR. Studies were excluded if case definition was not clearly defined or not consistently applied, RSV infection was not laboratory confirmed or based on serology alone, or if the report included fewer than 50 cases of acute lower respiratory infection. We applied a generalised linear mixed-effects model (GLMM) to estimate RSV-associated acute lower respiratory infection incidence, hospital admission, and in-hospital mortality both globally and regionally (by country development status and by World Bank Income Classification) in 2019. We estimated country-level RSV-associated acute lower respiratory infection incidence through a risk-factor based model. We developed new models (through GLMM) that incorporated the latest RSV community mortality data for estimating overall RSV mortality. This review was registered in PROSPERO (CRD42021252400)., Findings: In addition to 317 studies included in our previous review, we identified and included 113 new eligible studies and unpublished data from 51 studies, for a total of 481 studies. We estimated that globally in 2019, there were 33·0 million RSV-associated acute lower respiratory infection episodes (uncertainty range [UR] 25·4-44·6 million), 3·6 million RSV-associated acute lower respiratory infection hospital admissions (2·9-4·6 million), 26 300 RSV-associated acute lower respiratory infection in-hospital deaths (15 100-49 100), and 101 400 RSV-attributable overall deaths (84 500-125 200) in children aged 0-60 months. In infants aged 0-6 months, we estimated that there were 6·6 million RSV-associated acute lower respiratory infection episodes (4·6-9·7 million), 1·4 million RSV-associated acute lower respiratory infection hospital admissions (1·0-2·0 million), 13 300 RSV-associated acute lower respiratory infection in-hospital deaths (6800-28 100), and 45 700 RSV-attributable overall deaths (38 400-55 900). 2·0% of deaths in children aged 0-60 months (UR 1·6-2·4) and 3·6% of deaths in children aged 28 days to 6 months (3·0-4·4) were attributable to RSV. More than 95% of RSV-associated acute lower respiratory infection episodes and more than 97% of RSV-attributable deaths across all age bands were in low-income and middle-income countries (LMICs)., Interpretation: RSV contributes substantially to morbidity and mortality burden globally in children aged 0-60 months, especially during the first 6 months of life and in LMICs. We highlight the striking overall mortality burden of RSV disease worldwide, with one in every 50 deaths in children aged 0-60 months and one in every 28 deaths in children aged 28 days to 6 months attributable to RSV. For every RSV-associated acute lower respiratory infection in-hospital death, we estimate approximately three more deaths attributable to RSV in the community. RSV passive immunisation programmes targeting protection during the first 6 months of life could have a substantial effect on reducing RSV disease burden, although more data are needed to understand the implications of the potential age-shifts in peak RSV burden to older age when these are implemented., Funding: EU Innovative Medicines Initiative Respiratory Syncytial Virus Consortium in Europe (RESCEU)., (Copyright © 2022 The Author(s).

Few studies exist describing resources and care of pediatric patients with inborn errors of metabolism (IEM) admitted to pediatric intensive care unit (PICU). This study aims to characterize the PICU admissions of these patients to provide better diagnostic and therapeutic care in the future. Retrospective analysis of pediatric patients with IEM admitted to the PICU of a tertiary care center at a metabolic referral university hospital from 2009 to 2019 was included. Clinical information and demographic data were collected from PICU clinical records. During this period, 2% ( n  = 88 admissions, from 65 children) out of 4,459 PICU admissions had clinical features of IEM. The median age was 3 years (range: 3 days-21 years) and 33 were male. Median age at diagnosis was 3 months; 23/65 patients with intoxication disorders, 21/65 with disorders of energy metabolism, 17/65 with disorders of complex molecules, and 4/65 with other metabolic diseases (congenital lipodystrophy, Menkes' disease, hyperammonemia without a diagnosis). From a total of 88 admissions, 62 were due to metabolic decompensation (infection-38, neonatal period decompensation-14, external accident-5, prolonged fasting-2, and therapeutic noncompliance-3) and 26 elective admissions after a scheduled surgery/elective procedure. The most frequent clinical presentations were respiratory failure (30/88) and neurological deterioration (26/88). Mechanical ventilation was required in 30 patients and parenteral nutrition in 6 patients. Extracorporeal removal therapy was required in 16 pediatric patients (12 with maple syrup urine disease and 4 with hyperammonemia) with a median duration of 19 hours. The median length of PICU stay was 3.6 days (3 hours-35 days). Eight patients died during the studied period (cerebral edema-2, massive hemorrhage-5, and malignant arrhythmia-1). Acute decompensation was the main cause of admission in PICU in these patients. The complexity of these diseases requires specialized human and technical resources, with an important impact on the recovery and survival of these patients., Competing Interests: Conflict of Interest None declared., (Thieme.

Purpose: This literature review and meta-analysis aims to compare intraocular pressure (IOP) lowering efficacy, failure rates and loss of light perception (LP) rates 6 months after an IOP-lowering surgical procedure in neovascular glaucoma (NVG) eyes., Methods: MEDLINE and EMBASE were used as data sources. Only studies including NVG patients who underwent two different surgical approaches were considered. The treatment effect measures were (i) weighted mean difference (WMD) for IOP reduction, (ii) risk ratio (RR) for failure rates and (iii) risk difference (RD) for loss of LP. Outcome measures were reported with a 95% confidence interval (CI) and P < 0.05 was considered statistically significant. Analysis was performed using RevMan v5.0., Results: No RCT were retrieved. Seven comparative non-randomised studies were eligible. In glaucoma drainage devices (GDDs) vs cyclophotocoagulation arm, there was no statistical difference in IOP-lowering efficacy (WMD = - 3.63; CI [- 8.69, 1.43], P = 0.16), although failure rates and loss of LP were lower in the GDDs group (RR = 0.64, CI [0.41, 0.99], P = 0.05; and RD = - 0.15, CI [- 0.25, - 0.05], P = 0.004, respectively). In the Ahmed glaucoma valve (AGV) vs trabeculectomy arm, there was no statistical difference in IOP-lowering efficacy and loss of LP (WMD = 0.78, CI [- 2.29, 3.85], P = 0.62 and RD of 0.04, CI [- 0.05, 0.14], P = 0.34, respectively), but failure rates were lower in trabeculectomy group (RR of 2.25, CI [1.14, 3.71], P = 0.02)., Conclusions: There is lack of high-quality evidence on the subject as no RCT were retrieved comparing two different IOP-lowering procedures in NVG patients. Our findings are based, therefore, on non-RCT studies and should be interpreted with caution. There appears to be no difference in IOP-lowering efficacy between GDDs and cyclophotocoagulation, although GDDs appear to be safer. AGV and trabeculectomy also seem to provide similar IOP-lowering results with trabeculectomy showing lower failure rates.
