Corioamnionitis histológica y neurodesarrollo en niños prematuros menores de 34 semanas, Lima-Perú

Para determinar los efectos de la corioamnionitis histológica en el neurodesarrollo de los prematuros menores de 34 semanas evaluados a los 2 años de edad corregida se realizó un estudio secundario de casos y controles. Fueron analizados los datos clínicos, hallazgos histológicos de la placenta e índices del desarrollo medidos por la Escala Bayley III de 38 niños expuestos y 53 niños no expuestos. Las infecciones genitourinarias de la madre y la sepsis precoz fueron más frecuentes en el grupo expuesto (p<0,005). Las dimensiones del desarrollo cognitivo, motor y lenguaje fueron normales en ambos grupos. Los expuestos al subtipo subcorionitis obtuvieron menor desempeño en las tres dimensiones. La corioamnionitis histológica no mostró influencia sobre el neurodesarrollo en prematuros menores de 34 semanas a los 2 años de edad. Se recomienda estudios longitudinales y multicéntricos para definir los efectos a largo plazo.

SUMMARY The objective of this study was to determine the effects of histologically diagnosed chorioamnionitis on neurodevelopment of premature babies born with less than 34-week gestational age who were assessed at two-year corrected age. A secondary case-control study was carried out. Clinical data, placental histological findings, and development indexes assessed using the Bayley III scale were analyzed in 38 exposed children and 53 non-exposed children. Genitourinary infections in mothers and early sepsis were more frequent in the exposed group (p<0.005). Cognitive development, motor development and language were normal in both groups. Those children exposed to the chorionitis subtype had lower scores in the aforementioned variables. Histologically diagnosed chorioamnionitis did not show any influence on neurodevelopment in premature babies born with less than 34-week gestational age when they were assessed at two years. Longitudinal and multicenter studies are advised in order to define the long-term effects.

ABSTRACT Objective : to provide evidence-based clinical recommendations for the diagnosis and treatment of Duchenne Muscular Dystrophy. Methods : a guideline development group (GEG) was formed that included specialized physicians in the fields of neurology, neuropediatrics, genetics, and methodology. The GEG asked eight clinical questions to be answered by recommendations in this clinical practice guidelines (CPG). We conducted a systematic search and - when deemed relevant - primary studies in Medline, Scopus, and the Cochrane Controlled Register of Trials during 2021 were reviewed. Evidence was selected to answer each of the clinical questions posed. Certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. In periodic work meetings, the GEG used the GRADE methodology to review the evidence and formulate recommendations, points of good clinical practice, and a diagnosis and treatment flowchart. Results : this CPG addressed eight clinical questions, divided into three topics: screening, diagnosis, and treatment. Based on these questions, fifteen recommendations were formulated (10 strong, 5 conditional) and 11 points for good clinical practice. Conclusion : this paper summarizes the methodology and evidence- based conclusions of the CPG for the diagnosis and treatment of Duchenne muscular dystrophy.

Traumatismo encéfalo-craneano por caída libre en neonatos

Objetivo : Describir las características clínicas del traumatismo encéfalo craneano en neonatos. Materiales y métodos : Se realizó una serie de casos de neonatos con traumatismo encéfalo craneano, todos con diagnóstico clínico y tomográfico atendidos por el Servicio de Neuropediatría y Neonatología del Hospital Cayetano Heredia del 2014 al 2019. Resultados : Se incluyeron 12 neonatos, 67% (8/12) fueron varones, 33% (4/12) menores de cuatro días de edad y 25% (3/12) hijos de madres añosas. La caída libre fue el mecanismo de lesión en todos los casos y tres de ellos se cayeron de coches de paseo para bebés. El lugar más frecuente de la caída fue el hospital, tres neonatos se encontraban en alojamiento conjunto, dos en la sala de espera de la consulta externa y uno en hospitalización. El 83% (10/12) de los casos cayó de ≥ 0.5 m de altura y 33% (4/12) cayó de ≥ 1m. El 58% (7/12) fue sintomático a la caída, cuatro casos con letargia y uno con irritabilidad. Además, se reportaron vómitos y dificultad respiratoria. Cuatro presentaron hematoma epidural y tres de ellos fractura craneal, dos de gravedad por hipertensión endocraneana descompensada que requirieron evacuación quirúrgica de emergencia. Conclusión : El traumatismo encéfalo craneano en neonatos es un problema potencialmente grave. El hematoma epidural fue la lesión intracraneal más frecuente. La letargia e irritabilidad fueron los síntomas más frecuentes en los neonatos que cayeron de ≥ 0.5m de altura.

Objective : To describe clinical characteristics of head trauma in neonates. Material and methods : This is a case series of neonate patients with head trauma. All of them had a clinical diagnosis and computed tomography scans performed. They were taken care of in both Neuropediatrics and Neonatology services in Cayetano Heredia National Hospital in Lima, Peru from 2014 to 2019. Results : Twelve neonates were included, 67% (8/12) were male, 33% (4/12) were less than four days old, and 25% (3/12) were born to mature mothers. Free fall was the mechanism of lesion for all cases, and three of them fell down from baby trolleys. Places where these accidents occurred were at the hospital. Three neonates were in joint housing, two were in the waiting room of the outpatient clinic, and one fall occurred in the hospitalization ward. Eighty- three per cent (10/12) of all cases fell from ≥0.5- m height, and 33% (4/12) fell from 1- m height. Fifty-eight per cent (7/12) developed symptoms after the fall, four had lethargy and one had irritability. Also, vomits and respiratory distress were reported. Four neonates developed epidural hematoma and three had cranial fracture, two of these latter cases were severe because of decompensated cranial hypertension that required emergency surgical decompression. Conclusion : Head trauma in neonates is a potentially severe condition. Epidural hematoma was the most frequent intracranial lesion. Lethargy and irritability were most frequent symptoms in neonates who fell from ≥0.5- m height.

Acute Necrotizing Encephalopathy Associated With SARS-CoV-2 Exposure in a Pediatric Patient.

We present the case of a nine-month-old male child with three days of fever, irritability, left focal seizure, and febrile focal status epilepticus. He had no history of previous comorbidities. A lumbar puncture was performed, which showed cerebrospinal fluid (CSF) leukocytosis; protein and glucose were normal, and the polymerase chain reaction (PCR) panel for 14 pathogens in CSF was negative. Immunoglobulin G (IgG) qualitative and quantitative tests were positive for coronavirus disease 2019 (COVID-19) upon arrival. An MRI performed one week after the initial onset showed findings suggestive of acute necrotizing encephalopathy (ANE). The patient required mechanical ventilation. However, his symptoms did not improve and follow-up imaging two weeks later showed progression of the disease with hemorrhagic changes. To our knowledge, this is the first reported case of ANE associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-​2) infection in a pediatric patient.

El índice de correlación de prueba de ítems mostró un buen poder discriminatorio para la mayoría de los ítems (r> 0.30), con la excepción de un ítem para los meses 30, 36 y 48. Nuevos puntos de corte para los intervalos de edad entre 15 y 48 meses fueron determinados. Conclusiones: La versión en español de ASQ: SE-2 aplicada a padres de niños de 15 a 48 meses de edad en un entorno ambulatorio y en un área urbana de Lima-Perú, demostró ser una herramienta confiable y válida para la vigilancia y detección de etapas del desarrollo emocional.

SUMMARY Objectives: A study was carried out to determine the reliability, validity and cut-off points of the Spanish version of Ages & Stages Questionnaires: Social-Emotional, 2nd Edition (ASQ:SE-2). Material and Methods: Questionnaire forms of ASQ:SE-2 between 15 to 48 months were applied to parents of children chosen by convenience sampling. Reliability was determined by the internal consistency through Ordinal alpha coefficient (α), and validity of content through Item-test correlation (r). The cut-off points to establish risk zones were determined using the 65th percentile and ROC curve. Results: Two hundred thirty-six questionnaires were applied. The Ordinal alpha coefficient reached a between acceptable to good level (α = 0.73-0.87) for all 5 age-intervals questionnaires between 18 to 48 months. The Item-test correlation index pointed a good discriminatory power for most items (r > 0.30), with the exception of one item for the months 30, 36 and 48. New cut-off points for the intervals-age between 15 - 48 months were determined. Conclusions: The Spanish version of ASQ: SE-2, applied to parents of children from 15 to 48 months of age in an outpatient setting from an urban area of Lima-Peru proved to be a reliable and valid tool for surveillance and screening of steps of social-emotional development.

Effect of augmented reality books in salivary cortisol levels in hospitalized pediatric patients: A randomized cross-over trial.

OBJECTIVE: This study sought to assess the effect of reading augmented reality (AR) books on salivary cortisol levels in hospitalized pediatric patients compared to reading a standard children's book. METHODS: This was a randomized, two-period, cross-over trial in hospitalized children aged 7-11 years. AR books currently in the market were used as intervention. Complete block randomization was used to randomize the order of the intervention. Children allocated to the 'AR-first' group received the book, a tablet and were left to interact independently with the technology for an hour. After a 48 -h wash-out period, children received a standard book. 'Standard-book-first' group received only the standard book and after wash-out received the tablet and the AR book. Salivary cortisol and a validated visual analogue scale (VAS) for psychological stress were assessed at the beginning and at the end of each intervention. RESULTS: A total of 29 children were recruited in the study. One was lost during follow up. Cortisol levels decreased after the AR intervention (P = 0.019). Nevertheless, the decrease was not greater than the one associated to reading the standard book. VAS scores increased after the AR intervention (P < 0.001). DISCUSSION: There is evidence of order and sequence effects that might explain results. First assessment of AR-based interventions on stress. Results justify further research. CONCLUSIONS: There was no evidence that reading AR books diminished cortisol levels more than reading a standard book. AR-books improved VAS score for psychological stress compared to a standard book.

Conclusions : HIV was very frequent, severe and lethal in the TST28, half of the cases occurred in the first three days and the rest during the first two weeks of life. Associated factors were lower birth weight, labor, and pneumothorax.

Neonatal meningitis: a multicenter study in Lima, Peru. / Meningitis neonatal: estudio multicéntrico en Lima, Perú.

OBJECTIVE: To determine the incidence and the clinical, bacteriological and cerebrospinal fluid characteristics of neonatal meningitis in Lima hospitals. MATERIALS AND METHODS: An observational, multicenter study was conducted in six hospitals in the city of Lima during 1 year of epidemiological surveillance. RESULTS: The cumulative hospital incidence was 1.4 cases per 1000 live births. A total of 53 cases of neonatal meningitis were included, 34% (18/53) were early and 66% (35/53) late. The associated maternal factors were meconium-stained amniotic fluid and urinary tract infection. Insufficient prenatal check-ups were found in 58.8% (30/51). The most associated neonatal factor was sepsis. The main symptoms were fever, irritability, hypoactivity and respiratory distress. Pleocytosis in cerebrospinal fluid (CSF) was significant, without predominance of polymorphonuclear lymphocytes (PMN), hypoglycorrhagia and proteinorrhagia. The most frequent pathogens isolated were Escherichia coli and Listeria monocytogenes. CONCLUSIONS: The hospital incidence of neonatal meningitis was 1.4 per 1000 live births, being ten times higher in preterm infants. Breathing difficulty was the most frequent symptom in the early stage, while fever and irritability in the late stage. CSF showed pleocytosis without predominance of PMN. The most frequent germs were Escherichia coli and Listeria monocytogenes. Ventriculitis and hydrocephalus were the most common neurological complications.

En el líquido cefalorraquídeo (LCR) se destacó la pleocitosis, sin predominio de polimorfonucleares (PMN), hipoglucorraquia y proteinorraquia. Los patógenos aislados con mayor frecuencia fueron Escherichia coli y Listeria monocytogenes. CONCLUSIONES: La incidencia hospitalaria de meningitis neonatal fue de 1,4 por mil nacidos vivos, siendo diez veces mayor en prematuros. La dificultad respiratoria fue el síntoma más frecuente en la forma temprana, mientras que la fiebre e irritabilidad en la forma tardía. El LCR mostró pleocitosis sin predominio de PMN. Los gérmenes más frecuentes fueron Escherichia coli y Listeria monocytogenes. La ventriculitis e hidrocefalia fueron las complicaciones neurológicas más comunes.

Risk of brain damage in premature infants under 34 weeks of gestational age exposed to histological chorioamnionitis Lima, Peru. / Riesgo de daño cerebral en prematuros menores de 34 semanas expuestos a corioamnionitis histológica, Lima, Perú.

OBJECTIVES: To assess the risk of brain damage in premature infants under 34 weeks of gestational age exposed to histological chorioamnionitis (HCA). MATERIALS AND METHODS: A cohort study was conducted at the Hospital Cayetano Heredia, during 2015. Premature infants under 34 weeks of gestational age, who had histopathological examination of the placenta, were included. The types of HCA evaluated were sub-chorionitis, chorionitis, chorioamnionitis, with or without funisitis. Brain damage was evaluated in three age periods, between 0 and 7 days, between 7 and 30 days and at 40 weeks of corrected gestational age. A neurological follow-up and regular controls were performed with brain ultrasound. RESULTS: A total of 85 premature infants were included, 47.1% were women and the mean gestational age was 30.9 weeks. From the total, 42% (36/85) were born exposed to HCA. Premature rupture of membranes was the main cause of sepsis, which was related to neurological damage. HCA was associated with intraventricular hemorrhage (IVH) during the first week and with white matter lesions between 7 and 30 days of age (p = 0.035). The chorioamnionitis type of HCA was associated with neurological damage during the first week (RR = 2.11, 95% CI: 1.09-4.11) and between 7 and 30 days of age (RR = 2.72, 95% CI: 1.07-6.88). CONCLUSIONS: Chorioamnionitis was a risk factor for developing brain injuries in premature infants under 34 weeks of gestational age. It was also a risk factor for HIV during the first 7 days and for white matter injuries between 7 and 30 days of age. At 40 weeks of corrected gestational age, extreme premature infants with HCA had more extensive brain damage.

OBJETIVOS: Evaluar el riesgo de daño cerebral en prematuros menores de 34 semanas expuestos a corioamnionitis histológica (CAH). MATERIALES Y MÉTODOS: Se realizó un estudio de cohortes en el Hospital Cayetano Heredia, durante el 2015. Fueron incluidos prematuros menores de 34 semanas que tuvieran examen histopatológico de la placenta. Los tipos de CAH evaluados fueron subcorionitis, corionitis, corioamnionitis, con o sin funisitis. El daño cerebral se evaluó en tres periodos de edad, entre 0 y 7 días, entre 7 y 30 días y a las 40 semanas gestacionales corregidas. Se realizó un seguimiento neurológico y controles con ecografía cerebral. RESULTADOS: Se estudiaron 85 prematuros, 47,1% eran mujeres y la media de la edad gestacional fue de 30,9 semanas. El 42% (36/85) nacieron expuestos a CAH. La ruptura prematura de membrana fue la principal generatriz de sepsis, y la sepsis se relacionó con daño neurológico. La CAH estuvo asociada con hemorragia intraventricular (HIV) durante la primera semana y con lesiones de la sustancia blanca entre los 7 y 30 días de edad (p = 0,035). El tipo corioamnionitis de CAH se asoció al daño neurológico durante la primera semana (RR = 2,11; IC 95%: 1,09-4,11) y entre los 7 y 30 días de vida (RR = 2,72; IC 95%: 1,07-6,88). CONCLUSIONES: La corioamnionitis fue un factor de riesgo para desarrollar lesiones cerebrales en prematuros menores de 34 semanas, para HIV durante los primeros 7 días y lesiones de sustancia blanca entre los 7 y los 30 días de edad. A las 40 semanas de edad corregida, los prematuros extremos con CAH tuvieron lesiones cerebrales más extensas.

Case Report: Multiorgan Involvement with Congenital Zika Syndrome.

We report the case of an infant born with congenital Zika syndrome (CZS). During the largest Zika virus (ZIKV) outbreak in Peru, the mother presented with fever and rash that were confirmed to be due to ZIKV by real-time PCR. The infant was born with severe microcephaly. Imaging revealed corpus callosum dysgenesis, lissencephaly, ventriculomegaly, and calcifications. Mild hypertrophic cardiomyopathy with diastolic dysfunction was reported in the echocardiogram. Valgus deviation of the lower extremities and a left clubfoot were diagnosed at birth. The hip ultrasound showed incipient signs of Graf type II dysplasia. The findings confirm that CZS is a multiorgan phenotype in which microcephaly is merely the tip of the iceberg. A multidisciplinary approach is needed for the evaluation of these children.

La dificultad respiratoria fue el síntoma más frecuente en la forma temprana, mientras que la fiebre e irritabilidad en la forma tardía. El LCR mostró pleocitosis sin predominio de PMN. Los gérmenes más frecuentes fueron Escherichia coli y Listeria monocytogenes. La ventriculitis e hidrocefalia fueron las complicaciones neurológicas más comunes.

ABSTRACT Objective: To determine the incidence and the clinical, bacteriological and cerebrospinal fluid characteristics of neonatal meningitis in Lima hospitals. Materials and methods: An observational, multicenter study was conducted in six hospitals in the city of Lima during 1 year of epidemiological surveillance. Results: The cumulative hospital incidence was 1.4 cases per 1000 live births. A total of 53 cases of neonatal meningitis were included, 34% (18/53) were early and 66% (35/53) late. The associated maternal factors were meconium-stained amniotic fluid and urinary tract infection. Insufficient prenatal check-ups were found in 58.8% (30/51). The most associated neonatal factor was sepsis. The main symptoms were fever, irritability, hypoactivity and respiratory distress. Pleocytosis in cerebrospinal fluid (CSF) was significant, without predominance of polymorphonuclear lymphocytes (PMN), hypoglycorrhagia and proteinorrhagia. The most frequent pathogens isolated were Escherichia coli and Listeria monocytogenes. Conclusions: The hospital incidence of neonatal meningitis was 1.4 per 1000 live births, being ten times higher in preterm infants. Breathing difficulty was the most frequent symptom in the early stage, while fever and irritability in the late stage. CSF showed pleocytosis without predominance of PMN. The most frequent germs were Escherichia coli and Listeria monocytogenes. Ventriculitis and hydrocephalus were the most common neurological complications.

[Intraventricular hemorrhage and periventricular leukomalacia in low birth-weight neonates in three hospitals in Lima, Peru]. / Hemorragia intraventricular y leucomalacia periventricular en neonatos de bajo peso al nacer en tres hospitales de Lima, Perú.

To describe the frequency and severity of intraventricular hemorrhage and periventricular leukomalacia in low birth-weight neonates in three hospitals in Lima, Peru, 385 newborn babies weighing under 2,000 g at birth were evaluated between May 2012 and July 2014. Brain ultrasounds were obtained at 40 weeks' gestation, 3-5 days of life, and 3-4 weeks of life. Intraventricular hemorrhage occurred in 19.2% of neonates weighing under 1,500 g and was severe (grade III or with periventricular hemorrhagic infarction) in 9.6% of neonates under 1,500 g. Mortality in infants with intraventricular hemorrhage was 47.1%, while periventricular leukomalacia was found in 5.4% of neonates 1,500 g and under; both diagnoses were more frequent in lower-weight babies. The frequency of intraventricular hemorrhage is similar to that reported in other countries; however, severity and mortality are greater.

[Microcephaly in newborns in level II and III health facilities of the Ministry of Health of Peru]. / Microcefalia en recién nacidos en establecimientos de salud de nivel II y III del Ministerio de Salud de Perú.

OBJECTIVES.: To determine the ratio of microcephaly in newborns in level II and III health facilities of the Ministry of Health (MINSA) of Peru for the period 2005-2013. MATERIALS AND METHODS.: A secondary analysis of the databases of the Perinatal Information System was carried out during 2005-2013. Microcephaly was identified applying World Health Organization (WHO), Fenton, mixed (WHO-Fenton), and proportionality criteria. The ratios and indices of microcephaly were estimated per 10,000 live births (LB) by region and concordance was compared, using the WHO parameter as a reference. RESULTS.: The ratio of microcephaly during 2005 to 2013 was 3.4%, the average rate of microcephaly was 335 per 10,000 LBs according to the WHO criterion. The mixed parameter showed a substantial concordance (Kappa of 0.635), while the proportionality parameter showed a reasonable concordance (Kappa of 0.298). CONCLUSIONS.: The ratio of microcephaly in MINSA Level II and III health facilities was higher than that reported in other countries in the region before the appearance of Zika in the Americas. The frequency variations observed with those of other countries and among Peruvian regions could be explained by different factors, such as the technique for measuring head circumference, data capture, constitutional factors, and social determinants. We suggest standardizing measurements and their recording, harmonizing diagnostic criteria, and establishing health strategies to strengthen the epidemiological surveillance of the causes of microcephaly.

OBJETIVOS.: Determinar la proporción de microcefalia en recién nacidos en establecimientos de salud (EESS) de nivel II y III del Ministerio de Salud (MINSA) de Perú durante el periodo 2005-2013. MATERIALES Y MÉTODOS.: Se realizó un análisis secundario de las bases de datos del Sistema Informático Perinatal durante 2005-2013. La identificación de microcefalia se realizó aplicando los criterios de la Organización Mundial de la Salud (OMS), de Fenton, mixto (OMS-Fenton) y de proporcionalidad. Se estimaron las proporciones y tasas de microcefalia por 10 000 nacidos vivos (NV) por regiones y se comparó la concordancia, considerando al parámetro de OMS como referencia. RESULTADOS.: La proporción de microcefalia durante el 2005 a 2013 fue de 3,4%, la tasa promedio de microcefalia fue de 335 por 10 000 NV según el criterio de OMS. El parámetro mixto mostró una concordancia sustancial (Kappa de 0,635), mientras que el de proporcionalidad mostró una concordancia razonable (Kappa de 0,298). CONCLUSIONES.: La proporción de microcefalia en EESS de nivel II y III del MINSA fue mayor a lo reportado en otros países de la región antes de la aparición del Zika en las Américas. Las variaciones de las frecuencias observadas con las de otros países y entre las regiones peruanas, se podrían explicar por diferentes factores, como la técnica de medición del perímetro cefálico, captura de datos, factores constitucionales y determinantes sociales. Sugerimos estandarizar las mediciones y su registro, uniformizar los criterios de diagnóstico y establecer las estrategias sanitarias para fortalecer la vigilancia epidemiológica de las causas de la microcefalia.

Combined predictors of neurodevelopment in very low birth weight preterm infants.

OBJECTIVE: To evaluate the combined prognostic value of neurological examination, head circumference and cranial ultrasound for neurodevelopmental delay (NDD) in very low birth weight (VLBW, <1500 g) preterm infants. METHODS: Prospective follow-up study. Preterm infants with VLWB were assessed for NDD using the Mullen Scales of Early Learning test at 24 months of corrected age. Abnormal neurological examination (≥2 deviant items of Hammersmith neurological examination), microcephaly and major ultrasound abnormalities, each performed at term age, were evaluated as predictors of NDD in a multivariable Poisson model. RESULTS: 35/132 infants (26.5%) had NDD. In the multivariable analysis, microcephaly (RR, 3.2; 95% CI, 1.6-6.7) and major ultrasound abnormalities (RR, 2.7; 95% CI, 1.3-5.7) were associated to NDD. The combination of the two tests showed the highest positive predictive value (100%; 95% CI, 51%-100%), while the combination of normal neurological examination, no major US findings and normal head size at term showed the highest negative predictive value (89%; 95% CI, 78%-95%). The maximum under receiver operating characteristic curve area was for microcephaly or major ultrasound abnormalities (AUC 0.74 (0.65-0.83)). CONCLUSION: The combination of head circumference, cranial ultrasound and neurological examination at term age is useful to predict NDD in VLBW preterm infants.

Epilepsia en niños atendidos en el Hospital Nacional Cayetano Heredia de Lima, Perú, 2010- 2016: Lima, Peru, 2010-2016 / Clinical characteristics of epileptic children seen at Cayetano Heredia Hospital

La epilepsia es la principal causa de consulta neurológica en niños peruanos. Sin embargo, hay escasa información sobre sus características clínicas y epidemiológicas. Objetivos: Presentar las características clínicas de los niños epilépticos atendidos en el Hospital Cayetano Heredia, entre los años 2010 y 2016. Material y métodos: Se realizó un estudio observacional descriptivo, retrospectivo, tipo serie de casos, basado en las historias clìnicas de en niños menores de 14 años con diagnóstico de epilepsia, seguimiento clínico, registro electroencefalogràfico y neuroimagenes. Resultados: Se incluyeron 193 pacientes. El 47,2% (91/193) presentaron su primera crisis epiléptica antes del año de edad, cuya etiología fue secundaria en el 59,3% (54/91), destacando los factores perinatales y las malformaciones cerebrales. La etiología primaria fue más frecuente en los niños que iniciaron las crisis después del año de edad. Las crisis generalizadas se presentaron en 64,2% (124/193) sin diferencias por grupos etarios. El 69,9% (135/193) fueron controlados con un solo fármaco, en tanto que el 15% (29/193) fueron refractarios al tratamiento. La comorbilidad ocurrió en el 68,4% (132/193), siendo frecuentes el retraso del desarrollo psicomotor, el retardo mental y la parálisis cerebral. Conclusiones: La mayoría de los niños presentaron su primera crisis antes del año de edad, generalmente de causa secundaria. En los niños mayores fue prevalente la etiología primaria. La mayoría fueron controlados con monoterapia, pero se registró un porcentaje de refractariedad al tratamiento. La comorbilidad fue muy frecuente.

Epilepsy is the main cause of neurological clinical visits in Peruvian children. However, in our country, there is little information on its clinical and epidemiological characterizes. Objectives: To describe the clinical characteristics of children with epilepsy seen at the Cayetano Heredia Hospital, between 2010 and 2016. Material and Methods: A descriptive retrospective observational study was carried out, based on the clinical records of children under 14 years old with diagnosis of epilepsy, with clinical follow-up, electroencephalography and neuroimaging. Results: One hundred ninety-three patients were included. In 47.2% (91/193), the first seizure occurred before the one year of age; the etiology was secondary in 59.3% (54/91), with the main causes being perinatal events and cerebral malformations. Primary etiologies were more frequent in the children who started haviing seizures after one year of age. Generalized seizures ocurred in 64.2% (124/193) without differences by age groups. In 69.9% (135/193) seizures were controlled with a single drug while 15% (29/193) were refractory to treatment. Comorbidity occurred in 68,4% (132/193), with delays in psychomotor development, intellectual disability and cerebral palsy being frequent. Conclusions: Most children had their first seizures before the first year of age, usually with a secondary cause. In older children, the primary epilepsies were more prevalent. Monotherapy controlled the majority of children, but a percentage of refractoriness to the treatment was registered. Comorbidities were very frequent.

[Non-epileptic paroxysmal disorder in neonates]. / Trastornos paroxísticos no epilépticos neonatales.

Non-epileptic paroxysmal disorders are frequent events in the neonate, generally transient. However, due to their intensity they can be confused as true epileptic seizures. The objective of this review is to update the concepts in relation to tremors, neonatal benign sleep myoclonus (MNBS) and hyperekplexia. The tremors are very frequent, once identified it must be determined if they belong to a hyperexcitability syndrome related to maternal or perinatal factors, in idiopathic cases a good prognosis is expected. MNBS are often confused with epileptic seizures. They are characterized by the fact that myoclonus is brief and occurs only in sleep, children are normal, and the EEG is also normal. Hyperekplexia is a rare, genetically determined disorder characterized by hypertonia and exaggerated startle reactions to a banal stimulus, which can be improved with clonazepam.
