Asociación entre neuroimagen y secuelas neurológicas en pacientes con infección congénita por citomegalovirus / Association between neuroimaging findings and neurological sequelae in patients with congenital cytomegalovirus infection

Introducción: La infección congénita por citomegalovirus (CMV) supone una importante causa de discapacidad. Existen escasas evidencias acerca del valor pronóstico de las lesiones presentes en los estudios de neuroimagen. Objetivo: Analizar la gravedad de las lesiones en la resonancia magnética (RM) y la ecografía transfontanelar, y su relación con déficits neurológicos a largo plazo. Pacientes y métodos: Se realizó un estudio observacional analítico retrospectivo de 36 pacientes con infección congénita por CMV. Se revisaron los estudios de neuroimagen y se clasificaron según la escala de Noyola et al. modificada. Se relacionaron los hallazgos de neuroimagen con la afectación neurológica en su última visita en la consulta de neuropediatría. Resultados: Un total de 36 pacientes fueron estudiados, habiéndose realizado ecografía transfontanelar en 30 y RM cerebral en 29. La ecografía transfontanelar estuvo alterada en 20/30 pacientes, de los cuales, 11 tuvieron alteración en la RM (p = 0,04) y 10 afectación neurológica (p = 0,008). Tuvo una sensibilidad del 83,3%, IC 90%: 58-100 y una especificidad del 44,4%, IC 90%: 18,7-70,2 para la predicción de secuelas neurológicas. La RM estuvo alterada en 20/29 pacientes. Dieciséis de ellos tuvieron afectación neurológica (p < 0,001), teniendo una sensibilidad del 94%, IC 95%: 80-100 y una especificidad del 66,6%, IC 95%: 36-97,5 para la predicción de secuelas neurológicas. Una escala de Noyola et al. ≥ 2 se asoció a retraso psicomotor (p < 0,001). Conclusión: Nuestro trabajo valida los estudios previos en los que se encuentra correlación estadísticamente significativa entre la extensión de las lesiones en neuroimagen y la gravedad de los déficits neurológicos.

Background: Congenital cytomegalovirus (CMV) infection is an important cause of disability. There is little evidence on the prognostic value of lesions identified in neuroimaging studies. Aim: The study aimed to assess the severity of lesions detected with brain MRI and transfontanellar ultrasound and their relationship with long-term neurological deficits. Patients and methods: We performed a retrospective, analytical, observational study of 36 patients with congenital CMV infection. Neuroimaging studies were reviewed and classified according to the modified Noyola’ scale. Imaging findings were compared with neurological alterations in the patients’ most recent follow-up evaluation at the paediatric neurology department. Results: Thirty-six patients were studied (transfontanellar ultrasound: 30; brain MRI: 29). Twenty of 30 patients showed ultrasound abnormalities; of these, 11 showed alterations on brain MR images (P=.04) and 10 had neurological impairment (P=.008). Transfontanellar ultrasound had a sensitivity of 83.3%, 90% CI: 58-100 and a specificity of 44.4%, 90% CI: 18.7-70.2 for predicting neurological sequelae. Brain MRI displayed abnormalities in 20 of 29 patients, of whom 16 had neurological impairment (P<.001). MRI had a sensitivity of 94%, 95% CI: 80-100 and a specificity of 66.6%, 95% CI: 36-97.5 for predicting neurological sequelae. Modified Noyola’ scale values >2 were correlated with psychomotor retardation (P<.001). Conclusions: Our findings validate previous studies reporting a statistical significant correlation between the extension of neuroimaging lesions and severity of neurological deficits. (AU)

Quality of life and psychiatric comorbidities in pediatric patients with Gilles de la Tourette syndrome. / Calidad de vida y comorbilidades psiquiátricas en pacientes pediátricos con síndrome de Gilles de la Tourette.

INTRODUCTION: Tourette Syndrome (TS) is a complex neurodevelopmental disorder which is normally associated to psychiatric comorbidity such as attention deficit hyperactivity disorder, obsessive compulsive disorder, anxiety or depression. Quality of life (QoL) in these patients can be affected by tic severity and associated comorbidities. AIM: The aim of the study was to describe and analyze QoL and psychiatric comorbidities in a sample of pediatric patients, as well as to develop a Spanish version of the questionnaire CandA-GTS-QoL to measure quality of life in this population. PATIENTS AND METHODS: Single-center, observational, prospective study. Patients aged 6 to 16 years old with TS were included. Demographic, clinical, diagnostic and treatment data were gathered. Questionnaires regarding tic severity, psychiatric comorbidity and quality of life were used. RESULTS: Twenty-two patients with DSM-5 diagnosis of TS were included (86.4% male, median age 11 years). Of those, 86.4% had been previously diagnosed of psychiatric comorbidities and 72.7% received psychopharmacologic treatment. The prevalence of an ICD-10 current diagnosis of anxiety was 72.7%, depression 50%, ADHD 40.9% and OCD 7.3%. Median QoL score was 59.5 (RIC: 34.8-71.3) for PedsQL, and 55.5 (RIC: 45-65) for CandA-GTS-QoL, with a correlation between scores of R2 = 0.83 (p < 0.01). Higher tic severity was associated with poorer QoL (PedsQL R2: -0.732, p <0.01, CandA-GTS-QoL R2: -0.501, p = 0.021). A higher EDAH score for ADHD was associated with poorer QoL (PedsQL R2: -0.463, p = 0.03, CandA-GTS-QoL R2-0.534, p < 0.01). CONCLUSION: Prevalence of psychiatric comorbidities in pediatric TS is high and frequently underdiagnosed. Tics and psychiatric comorbidities affect quality of life. Further studies are needed to validate the Spanish version of CandA-GTS-QoL scale.

El síndrome de Gilles de la Tourette es un trastorno complejo que se acompaña habitualmente de comorbilidades psiquiátricas, como trastorno por déficit de atención/hiperactividad (TDAH), trastorno obsesivo-compulsivo (TOC), ansiedad o depresión. La calidad de vida de estos pacientes puede verse afectada por la gravedad de los tics y por la presencia de estas comorbilidades. Objetivos. Describir y relacionar la calidad de vida y las comorbilidades psiquiátricas en una muestra de pacientes pediátricos con síndrome de Gilles de la Tourette, así como proporcionar una versión en español del cuestionario Gilles de la Tourette Syndrome-Quality of Life Scale for Children and Adolescents (CandA-GTS-QOL) para medir la calidad de vida en esta población. Pacientes y métodos. Es un estudio transversal, observacional y unicéntrico. Se incluyó a pacientes entre 6 y 16 años con diagnóstico de síndrome de Tourette, de los cuales se recogieron datos demográficos y clínicos, así como diagnósticos y tratamientos previos. Se entregaron cuestionarios de gravedad de los tics, comorbilidad psiquiátrica y calidad de vida. Resultados. Se incluyó a 22 pacientes (86,4%, varones; mediana de edad, 11 años) con diagnóstico de síndrome de Gilles de la Tourette (según los criterios del Manual diagnóstico y estadístico de los trastornos mentales, quinta edición). El 86,4% tenía comorbilidades psiquiátricas diagnosticadas y el 72,7% recibía algún tratamiento. La prevalencia de ansiedad fue del 72,7%, la de depresión, del 50%, la de TDAH, del 40,9% y la de TOC, del 27,3%. La mediana de calidad de vida medida por el Pediatric Quality of Life Inventory (PedsQL) fue de 59,5 (rango intercuartílico: 34,8-71,3), y por la CandA-GTS-QOL, de 55,5 (rango intercuartílico: 45-65) (R2, 0,83; p menor de 0,01). La gravedad de los tics se relacionó con una peor calidad de vida (PedsQL, R2: ­0,707; p menor de 0,01; y CandA-GTS-QOL, R2: ­0,501; p = 0,021). Una mayor puntuación la escala de Conners revisada para el TDAH se relacionó con peor calidad de vida (PedsQL, R2: ­0,463; p = 0,03; y CandA-GTS-QOL, R2: ­0,534; p menor de 0,01). Conclusión. La prevalencia de comorbilidades psiquiátricas en el síndrome de Gilles de la Tourette en nuestro medio es alta y frecuentemente infradiagnosticada. Los tics y las comorbilidades psiquiátricas afectan a la calidad de vida. Son necesarios estudios que validen la CandA-GTS-QOL.

Association between neuroimaging findings and neurological sequelae in patients with congenital cytomegalovirus infection. / Asociación entre neuroimagen y secuelas neurológicas en pacientes con infección congénita por citomegalovirus.

BACKGROUND: Congenital cytomegalovirus (CMV) infection is an important cause of disability. There is little evidence on the prognostic value of lesions identified in neuroimaging studies. AIM: The study aimed to assess the severity of lesions detected with brain MRI and transfontanellar ultrasound and their relationship with long-term neurological deficits. PATIENTS AND METHODS: We performed a retrospective, analytical, observational study of 36 patients with congenital CMV infection. Neuroimaging studies were reviewed and classified according to the modified Noyola' scale. Imaging findings were compared with neurological alterations in the patients' most recent follow-up evaluation at the paediatric neurology department. RESULTS: Thirty-six patients were studied (transfontanellar ultrasound: 30; brain MRI: 29). Twenty of 30 patients showed ultrasound abnormalities; of these, 11 showed alterations on brain MR images (P=.04) and 10 had neurological impairment (P=.008). Transfontanellar ultrasound had a sensitivity of 83.3%, 90% CI: 58-100 and a specificity of 44.4%, 90% CI: 18.7-70.2 for predicting neurological sequelae. Brain MRI displayed abnormalities in 20 of 29 patients, of whom 16 had neurological impairment (P<.001). MRI had a sensitivity of 94%, 95% CI: 80-100 and a specificity of 66.6%, 95% CI: 36-97.5 for predicting neurological sequelae. Modified Noyola' scale values >2 were correlated with psychomotor retardation (P<.001). CONCLUSIONS: Our findings validate previous studies reporting a statistical significant correlation between the extension of neuroimaging lesions and severity of neurological deficits.

Molecular characterization of congenital myasthenic syndromes in Spain.

Congenital myasthenic syndromes (CMS) are a heterogeneous group of genetic disorders, all of which impair neuromuscular transmission. Epidemiological data and frequencies of gene mutations are scarce in the literature. Here we describe the molecular genetic and clinical findings of sixty-four genetically confirmed CMS patients from Spain. Thirty-six mutations in the CHRNE, RAPSN, COLQ, GFPT1, DOK7, CHRNG, GMPPB, CHAT, CHRNA1, and CHRNB1 genes were identified in our patients, with five of them not reported so far. These data provide an overview on the relative frequencies of the different CMS subtypes in a large Spanish population. CHRNE mutations are the most common cause of CMS in Spain, accounting for 27% of the total. The second most common are RAPSN mutations. We found a higher rate of GFPT1 mutations in comparison with other populations. Remarkably, several founder mutations made a large contribution to CMS in Spain: RAPSN c.264C > A (p.Asn88Lys), CHRNE c.130insG (Glu44Glyfs*3), CHRNE c.1353insG (p.Asn542Gluf*4), DOK7 c.1124_1127dup (p.Ala378Serfs*30), and particularly frequent in Spain in comparison with other populations, COLQ c.1289A > C (p.Tyr430Ser). Furthermore, we describe phenotypes and distinguishing clinical signs associated with the various CMS genes which might help to identify specific CMS subtypes to guide diagnosis and management.

Ischaemic stroke in children with cardiopathy: An epidemiological study. / Ictus isquémico en niños con cardiopatía: estudio epidemiológico.

INTRODUCTION: Ischaemic stroke is rare during childhood. Congenital and acquired heart diseases are one of the most important risk factors for arterial ischaemic stroke (AIS) in children. PATIENTS AND METHODS: We conducted a retrospective study of all children with AIS and heart disease diagnosed between 2000 and 2014. RESULTS: We included 74 children with heart disease who were eligible for inclusion. 60% were boys with a mean stroke age of 11 months. 20% of the patients died during the study period. 90% of the patients had a congenital heart disease, while cyanotic heart disease was identified in 60%. Hypoplastic left heart syndrome was the most frequent heart disease. In 70% of patients AIS was directly associated with heart surgery, catheterisation or ventricular assist devices. Most patients with AIS were in the hospital. Seizures and motor deficit were the most frequent symptoms. Most patient diagnoses were confirmed by brain CT. The AIS consisted of multiple infarcts in 33% of the cases, affected both hemispheres in 27%, and involved the anterior and posterior cerebral circulation in 10%. CONCLUSIONS: Arterial ischaemic strokes were mainly associated with complex congenital heart diseases, and heart procedures and surgery (catheterisation). AIS presented when patients were in-hospital and most of the patients were diagnosed in the first 24hours.

[Visuospatial functions and prematurity]. / Funciones visuoespaciales y prematuridad.

Visuospatial functions are very important in learning process and development of abstract thought during childhood. Several studies show that preterm and low birth weight infants obtain lower scores in test that assess cognitive functions, specially in the first year of life. These differences are attenuated over time, but a developmental delay that affects working memory and visuospatial process still persists. It is unclear what factors are involved in development of these functions, and pre- or perinatal factors may interfere with the proper conduct of the same, but have been described anatomical and physiological differences between the preterm and term brain that could explain somewhere in these alterations. The different selective vulnerability to hypoxia between immature brain in which preoligodendrocytes and subplate neurons predominate, and mature brain, determine differences in the pattern of injury from hypoxia with greater involvement of the periventricular white matter in preterm children. This lesional pattern leaves to a dysfunction in attentional and visuospatial process, due to the increased vulnerability of the regions involved in the dorsal pathway of visual processing.

TITLE: Funciones visuoespaciales y prematuridad.Durante la infancia, las funciones visuoespaciales son importantes en los procesos de aprendizaje y en el desarrollo del pensamiento abstracto. Diferentes estudios muestran que los niños prematuros o con bajo peso al nacer obtienen menores puntuaciones en los tests que valoran las funciones cognitivas, siendo estas diferencias mas pronunciadas durante el primer año de vida. Con el tiempo, estas diferencias se van atenuando, pero persiste un retraso madurativo que afecta a la memoria de trabajo y a los procesos visuoespaciales. No esta claro cuales son los factores implicados en el desarrollo de estas funciones y que factores pre o perinatales pueden interferir en su buen desarrollo, pero se han descrito diferencias anatomicas y fisiologicas entre el cerebro del niño pretermino y el termino que podrian explicar, en parte, alguna de estas alteraciones. La diferente vulnerabilidad selectiva a la hipoxia entre el cerebro inmaduro, en el que predominan las neuronas de la subplaca y los preoligodendrocitos, y el cerebro maduro del niño nacido a termino determinan diferencias en el patron de lesion por hipoxia con mayor afectacion de la sustancia blanca periventricular en el niño pretermino. Este patron lesional conlleva una disfuncion en los procesos atencionales y visuoespaciales debido a la mayor vulnerabilidad de las regiones que intervienen en la ruta dorsal del procesamiento visual.

Pancreatitis aguda: nuestra experiencia / Acute pancreatitis: our experience

Introducción: La pancreatitis aguda es un cuadro de dolor abdominal poco frecuente en la infancia. Nuestro objetivo es describir las características de los pacientes ingresados entre1988 y 2008 en un hospital terciario con este diagnóstico. Métodos: Estudio observacional retrospectivo por revisión de historias clínicas. Se recogen datos epidemiológicos, etiológicos, clínicos, de laboratorio, radiológicos, de manejo terapéutico y evolución clínica. Resultados: Incluimos 27 pacientes (un 66% varones), con una media de edad de 7,2 años (rango: 6 meses-16 años). El52% presenta enfermedades crónicas relevantes. El mecanismo etiológico más frecuente fue el estructural (37%), aunque hubo otros agentes causales, como ingesta de fármacos, infecciones, shock e inmunodeficiencias. Un 26% de los casos fueron catalogados como idiopáticos. El síntoma guía en todos los pacientes estables fue el dolor abdominal, de localización y características variables, acompañado de vómitos (55%), fiebre(33%), anorexia (19%) y otros síntomas relacionados con el agente causal. En todos se observó un aumento de las enzimas pancreáticas. La prueba de imagen más realizada fue la ecografía (patológica en un 74% de los casos), y el aumento del tamaño de la glándula fue el hallazgo más común. En el 89%de los pacientes el tratamiento fue médico, con dieta absoluta durante una mediana de 48 horas. Dos pacientes precisaron la realización de una colangiopancreatografía retrógrada endoscópica para el tratamiento de una coledocolitiasis. La duración media del ingreso fue de 9 días, y el 40% de los casos evolucionó favorablemente. Tres pacientes evolucionaron hacia pancreatitis crónica y 6 fallecieron por causas extradigestivas. Conclusiones: La pancreatitis aguda es una entidad poco frecuente en la edad pediátrica, con una amplia variedad de factores etiológicos que condicionan un pronóstico muy heterogéneo(AU)

Introduction: Acute pancreatitis is an unusual disorder in childhood that commonly onsets with sudden abdominal pain. Our goal is to describe the features of the patients diagnosed of acute pancreatitis between 1988 and 2008 who were admitted to our hospital. Methods: Retrospective observational study by review of medical records. We collected data referred to epidemiology, aetiology, clinical symptoms, analytical (amylase, lipase) and radiological findings, medical treatment administered and outcome. Results: We included 27 patients (66% males), with a mean age of 7.2 years (range: 6 months-16 years). 52% of them suffered from chronic diseases. The most common cause was a structural anomaly (37%). Other aetiologies included: drugs, infections, shock and immunodeficiencies. 26% of cases were catalogued as idiopatic. The presenting symptom in non-critical patients was abdominal pain, in different areas and with diverse features, associated with vomiting (55%), fever (33%),anorexia (19%) and other symptoms related to the a etiological agent. Pancreatic enzyme levels were elevated in all patients. The most widely used radiological test was ecography (abnormalin 74%), being the most common image the enlargement of the gland. 89% of patients were managed conservatively with complete bowel rest during a median of 48 hours. ERCP was indicated in 2 patients to treat coledocolitiasis. Median hospital stay was 9 days, with favourable outcome in 40% of patients. Recurrence was described in 3 patients and 6 died because of non-digestive causes. Conclusions: Acute pancreatitis is an unusual disease in childhood with a great variety of aetiological factors that determine different prognosis(AU)

Estimulación precoz en los recién nacidos con peso al nacer entre 1.000 y 1.500 g. ¿Es siempre necesaria? / Early stimulation in newborns with birth weight between 1, 000 and 1, 500 g: is it always necessary?

Objetivo: Determinar si la práctica actualmente generalizada de envío de todos los prematuros nacidos entre 1.000 y 1.500 g al nacer a centros de atención temprana es necesaria desde el punto de vista neurológico o si es posible establecer unos criterios de selección. Material y métodos: Estudio retrospectivo de los recién nacidos (RN) en nuestro hospital entre enero de 1998 y diciembre de 2004 con peso al nacer comprendido entre 1.000 y 1.500 g, y seguidos al menos 2 años en la consulta de neuropediatría. Se analiza la significación pronóstica neurológica de las diferentes variables existentes en el periodo neonatal y con las de mayor significado se estableció un score para decidir el inicio de tratamiento de estimulación precozal alta de neonatología. Resultados: 194 recién nacidos cumplieron los criterios mencionados. Las variables de mayor significación fueron: edad gestacional (EG) < 28 semanas, sexo varón, hemorragia intraventricular de grado > I, antecedentes de embarazo de riesgo, sepsis, anemia con repercusión hemodinámica y fundamentalmente exploración neurológica anormal al alta (odds ratio de 16).Se elaboró un score pronóstico cuyo punto de corte fue 4, con área bajo la curva del 88,3%. El valor predictivo positivo y el valor predictivo negativo fueron del 43,75 y el 96,2% respectivamente, con sensibilidad del 84,8% y especificidad del 78,9%.Conclusiones: Los RN con peso al nacer entre 1.000 y 1.500 g, con exploración neurológicanormal al alta y score pronóstico menor de 4 puntos no precisan estimulación precoz desde el punto de vista neurológico dada su previsible buena evolución (AU)

Objective: To determine whether the currently widespread practice of sending all premature infants with birth weight between 1,000 and 1,500 g to early care centres is necessary from a neurological point of view, or if it is possible to establish selection criteria. Material and methods: A retrospective study of newborns (NB) at our hospital between January 1998 and December 2004 with birth weight between 1,000 and 1,500 g, and followed up for atleast two years in a paediatric neurology clinic. We analysed the prognostic significance of the different neurological variables in the neonatal period, and those of greater significance were set at a score for deciding the start of early stimulation treatment on discharge from neonatology. Results: A total of 194 infants met the above criteria. The most significant neurological prognostic variables were: gestational age < 28 weeks, male sex, intraventricular haemorrhage grade >I, history of high risk pregnancy, sepsis, anaemia with haemodynamic repercussion and fundamentally abnormal neurological examination at discharge (odds ratio of 16). A prognostic score was developed with a cut-off of 4 points, with an area under the curve of 88.3%. The positive predictive value and negative predictive value were 43.75% and 96.2%, respectively, with 84.8%sensitivity and 78.9% specificity. Conclusions: The newborns with birth weight between 1,000 and 1,500 g and normal neurological examination at discharge, with a score of less than 4 points, do not require early stimulation treatment from a neurological standpoint, given its predictable good outcome (AU)
