RESUMO

BACKGROUND: The Centres for Disease Control and Prevention (CDC) broadened the focus of surveillance from ventilator-associated pneumonia to ventilator-associated event (VAE) for quality purposes. No paediatric definition of VAE (PaedVAE) has been accurately validated. We aimed to analyse the incidence and impact on patient outcomes resulting from the application of the adult and two paediatric VAE (PaedVAE) criteria. SECONDARY OBJECTIVE: to evaluate VAE/PaedVAE as factors associated with increased duration of mechanical ventilation (MV) and Paediatric Intensive Care Unit (PICU) stay. METHODS: Multicentre observational prospective cohort study in 15 PICUs in Spain. VAEs were assessed using the 2013/2015 CDC classification. PaedVAE were assessed using the CDC definition based on mean airway pressure (MAP-PaedVAE) versus a paediatric definition based on positive end-expiratory pressure (PEEP-PaedVAE). Children who underwent MV ≥ 48 h were included. RESULTS: A total of 3626 ventilator-days in 391 patients were analysed. The incidence of VAE, MAP-PaedVAE and PEEP-PaedVAE was 8.55, 5.24 and 20.96 per 1000 ventilator-days, respectively. The median time [IQR] for VAE, MAP-PaedVAE and PEEP-PaedVAE development from the MV onset was 4 [3-12.5], 4 [3-14], and 5 [3-7.75] days, respectively. Among survivors, all three were associated with increased MV duration (> 7 days) and PICU stay (> 10 days) at univariate analysis. Multivariate analysis showed that PEEP-PaedVAE was the only definition independently associated with MV above 7 days [OR = 4.86, 95% CI (2.41-10.11)] and PICU stay [OR = 3.49, 95% CI (1.68-7.80)] above ten days, respectively. CONCLUSIONS: A VAE definition based on slight PEEP increases should be preferred for VAE surveillance in children.

RESUMO

INTRODUCTION: We report three cases of sinus histiocytosis, a rare disease of unknown aetiology with massive lymphadenopathy (SHML), also known as Rosai-Dorfman (RD) disease, in a paediatric population. This proliferative histiocytic disorder is defined by histological and immunohistochemical (IHC) characteristics and can manifest as nodal involvement with variable enlargement of the lymph nodes (two cases) and extranodal manifestations involving skin and larynx involvement (one case). One patient had hypergammaglobulinemia. The morphological investigation revealed that all lymph nodes showed hyperplasia of sinuses with abundant histiocytic cell with intracytoplasmic lymphocytes. Skin and larynx biopsies showed a histiocyte and lymphocyte infiltrate with similar characteristics. An ultrastructural study was carried out on material from one patient. In the IHC study, SHML cells expressed phagocytic markers such as CD68 and S100, but markers for Langerhan's (CD1a) or dendritic cells (DRC, CD23 and CNA42) were absent. Two patients had a complete remission after surgical excision and no other treatment, but the third patient was treated with radiotherapy after a relapse with obstruction of the upper airway. CONCLUSION: This disorder must be considered in the differential diagnosis of young patients who exhibit massive or multiple lymphadenopathies, especially when involvement of the cervical area occurs. Due to the good outcome of the disease, a conservative approach is justified.
