RESUMO

Introduction. Therapeutic hypothermia (TH) reduces the risk of death or disability in children with moderate to severe hypoxic ischemic encephalopathy (HIE). Objective. To describe a population of patients with HIE that required TH and their course until discharge. Population and methods. Retrospective, descriptive, cohort study. All patients admitted to TH between 2013 and 2022 were studied. Epidemiological, clinical, monitoring, and treatment data were assessed, together with supplementary tests and condition at discharge. Risk factors were compared between deceased patients and survivors; and, among the latter, those requiring special healthcare needs (SHCN) at discharge. Results. A total of 247 patients were included. Mortality: 11%. Most common sentinel event: prolonged second stage of labor (39%). Treatment initiation: median of 5 hours of life. Seizures: 57%. Intravenous erythropoietin: 66.7%. Abnormal pattern in brain function monitoring: 52%. Normalization of monitoring: median of 24 hours. Pathological magnetic resonance imaging: 42%. Predictor variables of mortality: severe Sarnat and Sarnat staging and pathological ultrasound upon admission. Conclusion. The overall mortality rate was 11%. Referrals increased more markedly since 2018. The time of TH initiation was later than in previous reports. Severe neurological signs as per the Sarnat and Sarnat staging and a pathological baseline cranial ultrasound were independent predictors of mortality at discharge. Patients with SHCN at discharge showed a normalized tracing in the amplitude-integrated electroencephalography performed later. The most common finding in the magnetic resonance imaging was basal ganglia involvement. No statistically significant differences were observed in terms of clinical characteristics or complications among patients who received erythropoietin.


Introducción. La hipotermia terapéutica (HT) reduce el riesgo de muerte o discapacidad en niños con encefalopatía hipóxico-isquémica (EHI) moderada-grave. Objetivo. Describir una población de pacientes con EHI que requirió HT y su evolución hasta el alta hospitalaria. Población y métodos. Estudio descriptivo de cohorte retrospectivo. Se analizaron todos los pacientes que ingresaron a HT entre 2013 y 2022. Se evaluaron datos epidemiológicos, clínicos, de monitoreo, tratamiento, estudios complementarios y condición al alta. Se compararon los factores de riesgo entre pacientes fallecidos y sobrevivientes, y de estos, los que requirieron necesidades especiales al alta (NEAS). Resultados. Se incluyeron 247 pacientes. Mortalidad: 11 %. Evento centinela más frecuente: período expulsivo prolongado (39 %). Inicio del tratamiento: mediana 5 horas de vida. Convulsiones: 57 %. Eritropoyetina intravenosa: 66,7 %. Patrón anormal de monitoreo de función cerebral: 52 %. Normalización del monitoreo: mediana 24 horas. Resonancia magnética patológica: 42 %. Variables predictoras de mortalidad: Sarnat y Sarnat grave, y ecografía patológica al ingreso. Conclusión. La mortalidad global fue del 11 %. Las derivaciones aumentaron en forma más evidente a partir del año 2018. El horario de inicio de HT fue más tardío que en reportes anteriores. Los signos neurológicos de gravedad según la escala de Sarnat y Sarnat y la ecografía cerebral basal patológica fueron predictores independientes de mortalidad al alta. Los pacientes con NEAS presentaron normalización del trazado del electroencefalograma de amplitud integrada más tardío. El hallazgo más frecuente en la resonancia fue la afectación de los ganglios basales. No se encontraron diferencias clínicas ni de complicaciones estadísticamente significativas entre los pacientes que recibieron eritropoyetina.

RESUMO

OBJECTIVE: The aim of this study was to establish the effects of treprostinil in congenital diaphragmatic hernia (CDH) patients with persistent pulmonary hypertension (PHT) after 1 week of treatment. Drug effects were assessed by oxygenation index (OI), clinical end points, serial biochemical markers, and pre- and posttreatment echocardiogram. Treatment complications were also described. STUDY DESIGN: This is a quasi-experimental study of neonates with PHT admitted to the NICU within 48 hours showing persistent clinical instability, receiving mechanical ventilation with FiO2 > 60%, milrinone therapy, and inhaled nitric oxide. Clinical data were compared before and after treprostinil treatment. RESULTS: Seventeen neonates met the inclusion criteria. Median age was 17 days. Before treatment, median OI was 20 (IQR: 12-27). Suprasystemic PHT was estimated by echocardiogram in 8/17 patients; the rest were systemic. After 1 week of treatment, 15/17 patients were alive and median OI was 8 (IQR: 5-12, p = 0.0089). There were no statistically significant changes in laboratory data. Echocardiogram still showed suprasystemic PHT in 20% of patients. Adverse effects included hypotension, hematoma at the infusion site, and surgical persistent ductus arteriosus (PDA) closure in 4/17 patients. Fourteen patients were discharged. The median treatment time was 61 days. CONCLUSION: Treprostinil was well tolerated with satisfactory clinical response. Further studies are required to identify early responder subgroups.

RESUMO

El péptido natriurético B (PNB) es un péptido responsable de los cambios durante la organogénesis del corazón y en la transición a la vida extrauterina. En la primera semana de vida, los niveles de PNB son altos y se normalizan con el descenso fisiológico del peso. Valores elevados de PNB se han asociado a diferentes patologías. Objetivo. Establecer la relación entre los niveles de PNB y la criticidad y evolución a corto plazo en pacientes internados en la Unidad de Cuidados Intensivos Neonatales. Método. Estudio observacional analítico de una cohorte prospectiva. Se definió criticidad como requerimientos de asistencia respiratoria con fracción inspirada de oxígeno mayor del 50% y/o inotrópicos. Se extrajeron 2 muestras de sangre con 72 h de diferencia. Resultados. Ingresaron 73 pacientes. Según la evolución al séptimo día del ingreso, se los dividió en 2 grupos: pacientes con buena evolución o con evolución grave persistente. La mediana del PNB inicial fue similar en ambos grupos (p: 0,15). La mediana de PNB a las 72 h fue mayor en los pacientes con evolución grave persistente (p: 0,005). Se calculó la diferencia entre ambos valores de PNB (ΔPNB: valor de PNB a las 72 h - valor de PNB a la hora cero). El ΔPNB presentó valores positivos en los pacientes con evolución grave persistente (X= 1260 pg/ml; rango: 4262094) y valores negativos en el grupo con buena evolución (X= -967 pg/ml; rango: -1656/-278) (p: 0,0002); sensibilidad: 87%; especificidad: 86%; valor predictivo positivo: 74%; y valor predictivo negativo: 93%. Conclusión. En este grupo de pacientes, el delta de PNB reflejó la evolución a corto plazo.


B-type natriuretic peptide (BNP) is responsible for changes in the heart organogenesis and is associated with transition to extrauterine life. In the first week of life, BNP levels are high and return to normal with the physiological loss in weight. High BNP levels are associated with different conditions. Objective. To establish the relationship between BNP levels and criticality and the short-term clinical course among patients hospitalized in the neonatal intensive care unit. Method. Observational and analytical study conducted in a prospective cohort. Criticality was defined as a requirement for assisted mechanical ventilation with a fraction of inspired oxygen of more than 50% and/or inotropes. Two blood samples were collected 72 hours apart. Results. Seventy-three patients were included in the study. Depending on their clinical course on day 7, they were divided into 2 groups: patients with a good clinical course or a persistent, severe clinical course. The median baseline BNP level was similar in both groups (p: 0.15). The median BNP level at 72 hours was higher among patients with a persistent, severe clinical course (p: 0.005). The difference between both BNP values was calculated (ΔBNP: BNP level at 72 hours - BNP level at 0 hours). The ΔBNP was positive among patients with a persistent, severe clinical course (X= 1260 pg/mL; range: 426-2094) and negative in the group with a good clinical course (X= -967 pg/mL; range: -1656/-278) (p: 0.0002); sensitivity: 87%; specificity: 86%; positive predictive value: 74%; and negative predictive value: 93%. Conclusion. In this group of patients, the delta-BNP value reflected the short-term clinical course.

RESUMO

Primary pyomyositis is an acute or subacute bacterial infection of skeletal muscle characterized by the formation of intramuscular localized abscess without a previous adjoining or remote infection. Although it is not frequent in our population, it is increasing because of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) emergency. For an early diagnosis and to avoid secondary complications a high degree of clinical suspicion is required. We report a case of primary pyomyositis in a boy without an underlying condition or previous infection.

RESUMO

La piomiositis primaria es una infección bacteriana aguda o subaguda del músculo esquelético caracterizada por la formación intramuscular de un absceso en ausencia de foco previo deinfección, contiguo o distante. Si bien es poco frecuente en nuestro medio, desde la aparición de Staphylococcus aureusmeticilino-resistente adquirido en la comunidad (SAMRC), se han descripto nuevos casos en niños. Su diagnóstico, que requiere un alto índice de sospecha, evita las complicaciones secundarias.Presentamos un caso de piomiositis primaria en un niño sin antecedentes ni patologías predisponentes.
