Cancer is not a risk factor for severe COVID-19 in children, except in patients with recent allogeneic hematopoietic stem cell transplantation or comorbidities.

The EPICO (Spanish general registry of COVID-19 in children)-SEHOP (Spanish Society of Pediatric Hematology and Oncology) platform gathers data from children with SARS-CoV-2 in Spain, allowing comparison between children with cancer or allogeneic hematopoietic stem cell transplantation (alloHSCT) and those without. The infection is milder in the cancer/alloHSCT group than in children without comorbidities (7.1% vs. 14.7%), except in children with recent alloHSCT (less than 300 days), of which 35.7% experienced severe COVID-19. These data have been shared with the SEHOP members to support treatment and isolation policies akin to those for children without cancer, except for those with recent alloHSCT or additional comorbidities. This highlights the collaborative registries potential in managing pandemic emergencies.

Case Report: Severe ARDS in a Pediatric Hematopoietic Stem-Cell Transplantation Recipient Caused by Disseminated Toxoplasmosis.

Toxoplasma gondii infection is a severe complication of hematopoietic stem-cell transplantation (HSCT) recipients that can remain unnoticed without a high clinical suspicion. We present the case of a 6-year-old patient with acute lymphoblastic leukemia and HSCT recipient who was admitted to the Pediatric Intensive Care Unit (PICU) on post-transplantation day +39 with fever, hypotension, severe respiratory distress and appearance of a lumbar subcutaneous node. She developed severe Acute Respiratory Distress Syndrome (ARDS) and underwent endotracheal intubation and early mechanical ventilation. Subsequently, she required prone ventilation, inhaled nitric oxide therapy and high-frequency oscillatory ventilation (HFOV). An etiologic study was performed, being blood, urine, bronchoalveolar lavage and biopsy of the subcutaneous node positive for Toxoplasma gondii by Polymerase Chain Reaction (PCR). Diagnosis of disseminated toxoplasmosis was established and treatment with pyrimethamine, sulfadiazine and folinic acid started. The patient showed clinical improvement, allowing weaning of mechanical ventilation and transfer to the hospitalization ward after 40 days in the PICU. It is important to consider toxoplasmosis infection in immunocompromised patients with sepsis and, in cases of severe respiratory distress, early mechanical ventilation should be started using the open lung approach. In Toxoplasma IgG positive patients, close monitoring and appropriate anti-infectious prophylaxis is needed after HSCT.

Patrón punta-onda continua en el sueño lento: nuestra experiencia durante 20 años / Continuous spike-waves during slow-wave sleep: Experience during 20 years

Introducción: La punta-onda continua durante el sueño lento (POCS) es un trazado electroencefalográfico característico, que aparece en la infancia y que en ocasiones condiciona un deterioro cognitivo. Este patrón electroencefalográfico puede aparecer tanto en determinados síndromes epilépticos como en la evolución de epilepsias idiopáticas y sintomáticas. El objetivo de nuestro estudio es analizar las características epidemiológicas y clínicas de pacientes que presentan en algún momento de su evolución POCS, describir la respuesta a distintos tratamientos y estudiar factores predictores de su evolución. Métodos: Estudio observacional retrospectivo de pacientes pediátricos con POCS seguidos en un hospital terciario en el periodo de noviembre 1997 a noviembre 2017. Resultados: Obtuvimos una muestra de 25 pacientes (68% varones). El 76% presentaba de base alteraciones en pruebas de neuroimagen o retraso psicomotor (POCS secundaria). El 24% restante eran niños sanos o con epilepsias benignas (POCS primaria). La edad media al inicio de la POCS fue de 6,7 años, siendo menor en los casos secundarios. Durante el periodo de POCS, el 72% presentó alguna manifestación clínica añadida. Todos recibieron combinaciones de antiepilépticos, siendo eficaces en el 36%. La POCS cesó en el 72%, siendo más probable el cese cuanto más tarde se hubiera instaurado. Un tercio tuvo alguna secuela, principalmente alteraciones cognitivas y del comportamiento, más frecuentes en POCS secundaria y en los pacientes en que duró más tiempo. Conclusiones: El trazado electroencefalográfico de POCS, aunque infrecuente, supone un reto terapéutico. Es importante seguir a los pacientes con epilepsia, especialmente si asocia deterioro neurológico, para detectar la presencia POCS e iniciar tratamiento precoz

Introduction: Continuous spikes and waves during slow sleep (CSWS) is an EEG pattern that appears during childhood, and is often associated with cognitive impairment. It can appear in the course of epileptic syndromes, as well as in benign epilepsy. The aim of this study is to analyse epidemiological and clinical characteristic of patients with CSWS, in order to describe possible predictive factors in their outcome. Methods: A retrospective study was conducted on paediatric patients with CSWS treated in a third-level hospital from November 1997 to November 2017. Results: The study included 25 patients (68% male), of whom 76% had abnormalities in the neuroimaging or suffered from psychomotor development disorder (secondary CSWS). The rest were healthy, or diagnosed with idiopathic epilepsy. The mean age of onset of CSWS was 6.7 years, but earlier in the secondary CSWS cases. Symptoms were present during the CSWS episode in 72% of cases. All of them were treated with antiepileptic drugs, which were effective in 36%. CSWS stopped in 72%, and remission was longer if the CSWS onset occurred at an older age. One-third (33%) presented with sequelae, mostly cognitive and behavioural alterations. Outcome was poorer in those with secondary CSWS and, in those whose CSWS started at an earlier age and lasted longer. Conclusion: The CSWS pattern, although rare, is still a therapeutic challenge. A close follow-up of the patients with epilepsy is important, especially if associated with cognitive impairment, in order to establish an early diagnosis and treatment

Disminuyendo el dolor en los procedimientos invasivos durante la hospitalización pediátrica: ¿ficción, realidad o realidad virtual? / Reducing the pain in invasive procedures during paediatric hospital admissions: Fiction, reality or virtual reality?

Introducción: La realización de procedimientos invasivos dolorosos con fines terapéuticos o diagnósticos en pacientes pediátricos hospitalizados es frecuente en la práctica diaria. Se deben buscar estrategias encaminadas a disminuir el dolor y la ansiedad durante estas técnicas, como el uso de realidad virtual (RV). Materiales y métodos: Se realizó un estudio observacional, analítico y prospectivo, en el cual se incluyeron todos los pacientes pediátricos hospitalizados de entre 4 y 15 años que precisaron procedimientos invasivos. Se recogieron escalas de valoración de dolor y ansiedad a los pacientes (ajustadas a su edad), familiares y personal sanitario y se comparó el uso de la RV, de manera aislada y asociado a una crema anestésica (prilocaína/lidocaína crema 2,5%), con un grupo control en el que no se utilizó ninguna técnica analgésica. Resultados: Se incluyeron 58 pacientes, de los cuales 38 usaron la RV (grupo RV) y 20 pacientes no recibieron ninguna técnica analgésica ni de distracción (grupo control). El uso de RV disminuyó las puntuaciones en la mediana de las escalas de dolor en niños, familiares y personal sanitario (grupo control 4/5 vs. grupo RV 1/5, p < 0,001), y en las escalas de ansiedad en niños (grupo control 4/5 vs. grupo RV 1/5, p = 0,001). En el análisis multivariante, el número de punciones (R2: 0,5; β: 0,6; p = 0,01) y la ausencia de técnicas coadyuvantes (β: -0,9; p = 0,02) se asociaron con puntuaciones más elevadas en la escala del dolor en niños. Comentarios: El empleo de RV disminuy:e el dolor y la ansiedad durante la realización de procedimientos invasivos en pacientes pediátricos hospitalizados

Introduction: Potentially painful invasive procedures are often performed for diagnostic or therapeutic purposes in hospitalised paediatric patients. Approaches, such as virtual reality (VR), should be sought in order to minimise pain and anxiety during these procedures. Materials and methods: Hospitalised patients between 4 and 15-years-old requiring an invasive procedure were included. Pain and anxiety evaluation scales were given to children, relatives and health workers. A comparison was made with patients in whom VR was used (with or without concomitant use of a prilocaine/ lidocaine 2.5% analgesic cream) and patients in whom neither VR nor analgesic cream were used. Results: The study included 58 patients, 38 in the VR group and 20 in the control group. Pain scores, as performed by patients, relatives and health workers, significantly decreased in the VR group (control group median 4/5 vs. VR group median 1/5, P < .001). Patient-reported anxiety scales were also lower in the VR group (control group median 4/5 vs. VR group 1/5, P = .001). The number of punctures (R2: 0.5, β: 0.6; P = .01) and the lack of analgesic techniques (β: -0.9; P = .02) were associated with higher scores in patient-reported pain scales. Comments: The use of VR can reduce pain and anxiety during invasive procedures in hospitalized children

Pain scores, as performed by patients, relatives and health workers, significantly decreased in the VR group (control group median 4/5 vs. VR group median 1/5, P<.001). Patient-reported anxiety scales were also lower in the VR group (control group median 4/5 vs. VR group 1/5, P=.001). The number of punctures (R2: 0.5, ß: 0.6; P=.01) and the lack of analgesic techniques (ß: -0.9; P=.02) were associated with higher scores in patient-reported pain scales.
