ABSTRACT

BACKGROUND: Bronchopulmonary dysplasia (BPD) is still a major concern in preterm infants and adequate screening methods for secondary right ventricle (RV) failure are needed. Early detection could be aided by taking measurements of RV deformation using speckle tracking echocardiography. A prospective longitudinal study was carried out over 28 months at a tertiary care pediatric cardiology center. Preterm infants < 32 weeks gestational age (GA) were eligible for the study. Enrolled patients were separated in two groups: NO-BPD or BPD. At three timepoints over the first year of life, echocardiogram measurements were performed. Right ventricle strain was studied using speckle tracking analysis and compared to conventional function parameters. RESULTS: Fifty patients were enrolled in the study, 22 in the NO-BPD group and 28 in the BPD group. RV strain showed no statistical differences between groups. However, the BPD group showed worse RV function than the NO-BPD group, using speckle tracking analysis and other conventional parameters. During the study follow-up, an improvement trend is shown in RV strain. CONCLUSIONS: RV longitudinal strain and strain rate derived by speckle tracking is feasible in preterm infants. Although there seems to be a good correlation between RV strain and BPD severity, the results of this study were not conclusive. More studies should be carried out to investigate the optimum echocardiographic screening model of RV dysfunction in BPD patients.

ABSTRACT

La glomerulonefritis rápidamente progresiva de etiología posinfecciosa es rara en la infancia, con una prevalencia estimada del 1-3 %. La mayoría debuta como insuficiencia renal aguda y su tratamiento se basa en el uso de corticoides y ciclofosfamida. Si se realiza diagnóstico precoz, el 70 % presenta una recuperación temprana de la función renal. En los últimos años, se han descrito "glomerulopatías por C3", que presentan características que se superponen. Son útiles, en el diagnóstico diferencial, la inmunofluorescencia y la determinación del factor nefrítico. Se presenta un varón de 4 años que acude por fiebre y cuadro respiratorio. Se observa microhematuria, proteinuria, descenso de filtrado glomerular y descenso de C3, y se sospecha glomerulonefritis aguda. Se realiza una biopsia, cuya microscopía óptica muestra la presencia de semilunas epiteliales, y la electrónica, depósitos subepiteliales en forma de joroba, por lo que se diagnostica glomerulonefritis rápidamente progresiva de etiología posinfecciosa.


Postinfectious glomerulonephritis is rarely presented as rapidly progressive glomerulonephritis in children; the prevalence is approximately 1-3 %. Most children have acute onset of renal failure; initial treatment involves corticosteroids and immunosuppressive therapy. Early diagnosis improves prognosis. In recent years, an entity known as "C3 glomerulopathies" has been described, presenting characteristics that overlap. In the differential diagnosis, the immunofluorescence and the determination of the nephritic factor are useful. We report a 4-year-old boy with fever, respiratory symptoms and hyporexia. Microhematuria, proteinuria, decline in glomerular filtration and depressed C3 were found. Acute glomerulonephritis was suspected. Renal biopsy showed crescent formation, immunofluorescence staining for C3 and subepithelial humps. Therefore, postinfectious glomerulonephritis with crescent formations was diagnosed.

ABSTRACT

Antecedentes y objetivo: el ductus arterioso persistente hemodinámicamente significativo (DAP-HS) se asocia a mayor riesgo de enterocolitis necrotizante (ECN) y peor tolerancia enteral en los recién nacidos prematuros (RNPT). Se ha demostrado asociación entre el propéptido natriurético cerebral (proBNP) y el DAP-HS. Nuestro objetivo fue analizar la relación entre los niveles de proBNP y la tolerancia enteral, el riesgo de ECN y la ganancia ponderal en el RNPT. Material y métodos: estudio retrospectivo observacional, que incluyó a RNPT menores de 32 semanas de gestación y/o 1.500 g, con estudio ecocardiográfico y determinación de niveles de proBNP a las 48-72 horas de vida. Resultados: de 117 pacientes incluidos, el 65,8% tuvo un DAPHS y el 9,4% presentó ECN confirmada. El DAP-HS se asoció a mayor duración de la nutrición parenteral (p < 0,001), a ECN confirmada (p = 0,006) y a peor ganancia ponderal durante el ingreso (p < 0,001). Los valores de proBNP se relacionaron con la ECN (no ECN 12.189,5 pg/ml, rango 654-247.986; ECN 41.445 pg/ml, rango 15.275-166.172; p < 0,001), sin encontrar asociación con el resto de variables de evolución digestiva. En el análisis multivariante de regresión logística, las variables relacionadas de forma independiente con el desarrollo de ECN fueron la edad gestacional y el proBNP superior a 22.400 pg/ml (OR 13,386; IC 95% 1,541-116,262; p = 0,019). Conclusiones: el proBNP podría ser un marcador precoz de patología digestiva grave en el RNPT. Los niveles elevados podrían relacionarse con mayor riesgo de ECN en los neonatos más inmaduros


Background and objective: hemodynamically significant patent ductus arteriosus (HS-PDA) is associated with an increased risk of necrotizing enterocolitis (NEC) and worse enteral tolerance in preterm newborns (PN). An association has been demonstrated between brain natriuretic propeptide (proBNP) and HS-PDA. Our objective was to analyze the relationship between proBNP levels and enteral tolerance, NEC risk and weight gain in PN. Material and methods: a retrospective study was performed in neonates born before 32 weeks' gestation or with birth weight below 1500 grams, in whom proBNP determination and echocardiography were performed at 48 to 72 h of life. Results: 117 patients were included. 65.8% had a HS-PDA and 9.4% had an outcome of NEC. HS-PDA was associated with longer duration of parenteral nutrition (p < 0.001), a confirmed NEC (p = 0.006) and worse weight gain during admission (p < 0.001). ProBNP levels were associated to NEC (no NEC 12189.5 pg / mL, range 654-247986; NEC 41445 pg/mL, range 15275-166172, p < 0.001). No association was found with the rest of gastrointestinal outcomes. Multivariate logistic regression analysis showed a significant association of NEC with gestational age and proBNP above 22,400 pg/mL (OR 13,386, 95% CI 1,541-116,262, p = 0.019). Conclusions: proBNP could be an early marker of severe digestive pathology in PN. Increased proBNP levels could be associated with a significant increased risk of NEC in very immature newborns

ABSTRACT

Introducción. Los pacientes con neurofibromatosis de tipo 1 (NF1) tienen una gran predisposición a desarrollar déficit de atención. El objetivo del estudio es determinar los pacientes controlados en nuestra sección de neuropediatría con NF1 y diagnóstico de trastorno por déficit de atención/hiperactividad (TDAH), valorando la adhesión y respuesta al tratamiento. Pacientes y métodos. Se identifica a los pacientes afectos de NF1 que siguen controlados entre el 31 de diciembre de 2015 y el 31 de junio de 2017, y de ellos, los que presentan diagnóstico de TDAH, revisando datos clínicos y de tratamiento. Resultados. Se ha controlado a 56 pacientes afectos de NF1, con una edad media de 9,83 ± 4,17 años. De ellos, 23 (41%) presentan diagnóstico clínico de TDAH, con una edad media de 7,53 ± 2,46 años en el momento del diagnóstico. El 48,8% de los niños en edad escolar está afecto de TDAH. Todos los pacientes menos uno recibieron tratamiento con estimulantes, con un tiempo medio de tratamiento de 3,85 ± 3,04 años. Continúan con el tratamiento 19 pacientes de los 22 tratados (86%). Once casos refieren una clara mejoría, y ocho, una mejoría moderada. Conclusiones. El TDAH es muy prevalente en niños con NF1. Se destaca la importancia de la identificación y el tratamiento del TDAH en niños afectos de NF1. Nuestra revisión muestra una buena adhesión al tratamiento con estimulantes, con mantenida buena respuesta en la mayor parte de los casos


Introduction. Patients with neurofibromatosis type 1 (NF1) have a high predisposition to develop attention-deficit disorder. The aim of this study is to determine the prevalence of NF1 patients with attention-deficit/hyperactivity disorder (ADHD) diagnosis attending our Child Neurology Department. We assess patient adherence and medical treatment outcomes. Patients and methods. Identification of patients with NF1 being followed up from December 31 2015 to June 31 2017 with ADHD diagnosis. Clinical and treatment data were collected. Results. 56 patients with NF1 were enrolled in the study with a mean age of 9.83 ± 4.17 years. 23 patients (41%) were diagnosed with ADHD, mean age at ADHD diagnosis of 7.53 ± 2.46 years. School-age children with ADHD represented 48.8% of cases. All but one of the children received treatment, mean duration of treatment was 3.85 ± 3.04 years. 19 out of 22 patients (86%) continue medical treatment. Positive effects were reported by eleven patients with a moderate response in eight patients. Conclusions. Prevalence of ADHD in patients with NF1 is high. Early diagnosis and treatment of ADHD in patients with NF1 is highlighted by this study. Our study reveals good patient adherence and medical treatment outcomes in most patients

ABSTRACT

Resumen ANTECEDENTES: El síndrome de Ballantyne es un cuadro poco frecuente asociado con hidrops fetal, en el que la madre refleja los síntomas fetales. Es decisivo diferenciarlo de la preeclampsia porque comparten signos de hipertensión y proteinuria. Su etiopatogenia se desconoce pero se han propuesto teorías asociadas con el desequilibrio entre factores angiogénicos y antiangiogénicos. CASO CLÍNICO: Paciente de 29 años, controlada en la consulta de Medicina Materno-Fetal debido al antecedente de síndrome de Ballantyne en el embarazo previo. En la ecografía de control a las 26 semanas se detectaron placentomegalia, ascitis fetal e incremento del líquido amniótico. Las ecografías posteriores demostraron polihidramnios e hidrops a las 28 semanas. Enseguida de la aparición del edema se estableció el diagnóstico de síndrome del espejo recidivante e hidrops no inmunitario. Se hospitalizó para drenaje del líquido. La amniorrexis se produjo a las 29 + 6 semanas. Una semana después se inició la dinámica uterina y el embarazo finalizó a las 31 semanas, después de la ruptura prematura de membranas. El neonato fue un varón de 3200 g, Apgar 2-6-8 al minuto, 5 y 10 minutos, respectivamente. Después del estudio postnatal se estableció el diagnóstico de perforación ileal múltiple. El recién nacido requirió 5 intervenciones quirúrgicas, con posoperatorio tórpido y se dio de alta a los 3 meses de vida. CONCLUSIONES: El síndrome del espejo es infradiagnosticado, a pesar de su potencial para complicar gravemente el embarazo asociado con hidrops. La recuperación de la madre suele ser favorable a los pocos días de posparto aunque la morbilidad y la mortalidad fetal son elevadas.


Abstract BACKGROUND: Ballantyne syndrome is characterized by the triad: fetal, placental and maternal edema. It is an uncommon condition associated with fetal hydrops, in which mother reflects fetal symptoms. It is essential to differentiate from preeclampsia, since there are common signs such as hypertension and proteinuria. Etiopathogenesis is unknown, although theories associated with an imbalance between angiogenic and antiangiogenic factors have been postulated. Treatment consists of ending the pregnancy or improving the fetal situation. CLINICAL CASE: We present the case of a 29-years pregnant woman controlled in the Maternal-Fetal Medicine Unit due to the history of Ballantyne Syndrome in the previous gestation. In the follow-up ultrasound performed at 26-weeks, placentomegaly, fetal ascites and increased amniotic fluid were detected. Subsequent ultrasounds showed polyhydramnios and fetal hydrops at 28-weeks. After maternal edema began, she was diagnosed with recurrent Mirror Syndrome and non-immune hydrops. Admission was indicated and amniodrainage was performed due to symptomatic polyhydramnios. Finally, premature rupture of membranes occurred at 29+6-weeks. She started uterine dynamic after one week, ending in a preterm delivery at 31-weeks after premature rupture of membranes. A 3200gr male was born with Apgar Scores 2-6-8 at 1, 5 and 10min respectively and, after postnatal study, he was diagnosed with multiple ileal perforation. Five surgical interventions were necessary, with a complicated postoperative period and could be discharged at 3 months of age. CONCLUSIONS: Mirror syndrome is an underdiagnosed pathology of unknown incidence that can seriously complicate gestation associated with fetal hydrops. Maternal recovery is favorable few days after delivery, but it leads to high fetal morbi-mortality.

ABSTRACT

La estenosis de la arteria renal es una causa rara de hipertensión arterial neonatal de origen renovascular. Hay muy pocos casos descritos en la literatura en esta etapa. La mayor parte de los pacientes con esta afectación permanecen asintomáticos, y la hipertensión se detecta en las revisiones pediátricas rutinarias. El diagnóstico puede realizarse mediante la combinación de hallazgos bioquímicos y radiológicos. El manejo inicial del paciente se basa en terapia farmacológica hasta alcanzar un crecimiento adecuado para evaluar la reparación definitiva de la lesión vascular o la nefrectomía en caso de supresión funcional del riñón afecto. Se presenta a una paciente femenina recién nacida a término, con hipertensión arterial e importante falla cardíaca congestiva, originada por una estenosis unilateral de la arteria renal, con supresión funcional y atrofia del riñón afecto, que precisó importante soporte inotrópico y antihipertensivo durante los primeros días de vida, con importante mejoría clínica posterior.


Renal artery stenosis represents a rare cause of neonatal arterial hypertension of renovascular origin, having been described few cases in the literature at this stage of life. Most patients with this disease remain asymptomatic; hypertension can be detected in routine pediatric revisions. Diagnosis can be performed by combining biochemical and radiological findings. The initial management consists of pharmacological therapy in order to achieve adequate growth. Subsequently, it is necessary to assess definitive repair of the vascular lesion or nephrectomy in the case of functional abolition of the affected kidney. We present a term newborn female, with arterial hypertension and an important congestive heart failure, caused by a unilateral renal artery stenosis, with functional abolition and atrophy of the affected kidney, which required an important inotropic and antihypertensive support during her first days of life, with significant clinical improvement subsequently.
