Evaluation of the clinical effect of an artificial intelligence-assisted diagnosis and treatment system for neonatal seizures in the real world: a multicenter clinical study protocol / 中国当代儿科杂志

Neonatal seizures are the most common clinical manifestations of critically ill neonates and often suggest serious diseases and complicated etiologies. The precise diagnosis of this disease can optimize the use of anti-seizure medication, reduce hospital costs, and improve the long-term neurodevelopmental outcomes. Currently, a few artificial intelligence-assisted diagnosis and treatment systems have been developed for neonatal seizures, but there is still a lack of high-level evidence for the diagnosis and treatment value in the real world. Based on an artificial intelligence-assisted diagnosis and treatment systems that has been developed for neonatal seizures, this study plans to recruit 370 neonates at a high risk of seizures from 6 neonatal intensive care units (NICUs) in China, in order to evaluate the effect of the system on the diagnosis, treatment, and prognosis of neonatal seizures in neonates with different gestational ages in the NICU. In this study, a diagnostic study protocol is used to evaluate the diagnostic value of the system, and a randomized parallel-controlled trial is designed to evaluate the effect of the system on the treatment and prognosis of neonates at a high risk of seizures. This multicenter prospective study will provide high-level evidence for the clinical application of artificial intelligence-assisted diagnosis and treatment systems for neonatal seizures in the real world.

Rapid diagnosis of respiratory distress syndrome by oral aspirate in premature newborns / Diagnóstico rápido da síndrome do desconforto respiratório por aspirado bucal em recém-nascidos prematuros

Abstract Objective: The stable microbubble test on gastric aspirate and on amniotic fluid has been used for the diagnosis of respiratory distress syndrome in the newborn. However, no study has performed this test on oral aspirates from premature infants. The objective of this study was to evaluate the performance of the stable microbubble test on oral aspirates from preterm newborns to predict respiratory distress syndrome. Method: This study included infants with gestational age <34 weeks. Oral fluids were obtained immediately after birth and gastric fluids were collected within the first 30 minutes of life. The samples were frozen and tested within 72 hours. Results: The sample was composed of paired aspirates from 64 newborns, who were divided into two groups: respiratory distress syndrome group (n = 21) and control group (n = 43). The median (interquartile range) of the stable microbubble count in the oral samples of infants with respiratory distress syndrome was significantly lower than that of infants who did not develop respiratory symptoms: respiratory distress syndrome group = 12 (8 -22) stable microbubbles/mm2; control group = 100 (48 -230) microbubbles/mm2 (p < 0.001). The correlation between microbubble count in gastric and oral aspirates was 0.90 (95% confidence interval = 0.85 -0.95; p < 0.001). Considering a cut-off point of 25 microbubbles/mm2, the sensitivity and the specificity of the stable microbubble test were 81.4% and 85.7%, respectively. Conclusion: The study suggests that the stable microbubble test performed on oral aspirate is a reliable alternative to that performed on gastric fluid for the prediction of respiratory distress syndrome in the newborn.

Resumo Objetivo: O teste das microbolhas estáveis no aspirado gástrico e no líquido amniótico foi usado no diagnóstico da síndrome do desconforto respiratório do recém-nascido. Contudo, nenhum estudo fez esse teste nos aspirados bucais de neonatos prematuros. O objetivo deste estudo foi avaliar o desempenho do teste das microbolhas estáveis em aspirados bucais de recém-nascidos prematuros para prever síndrome do desconforto respiratório. Método: Este estudo incluiu neonatos com idade gestacional < 34 semanas. Os fluidos orais foram obtidos imediatamente após o nascimento e os fluidos gástricos foram coletados nos primeiros 30 minutos de vida. As amostras foram congeladas e testadas em 72 horas. Resultados: A amostra foi composta de aspirados pareados de 64 recém-nascidos, divididos em dois grupos: grupo de síndrome do desconforto respiratório (n = 21) e grupo de controle (n = 43). A mediana (intervalo interquartil) da contagem das microbolhas estáveis nas amostras de fluido oral dos neonatos com síndrome do desconforto respiratório foi significativamente menor que a dos neonatos que não desenvolveram sintomas respiratórios: grupo de síndrome do desconforto respiratório = 12 (8-22) microbolhas estáveis/mm2; grupo de controle = 100 (48-230) microbolhas/mm2 (p < 0,001). A correlação entre a contagem das microbolhas nos aspirados gástricos e bucais foi 0,90 (intervalo de confiança de 95% = 0,85-0,95; p < 0,001). Considerando um ponto de corte de 25 microbolhas/mm2, a sensibilidade e a especificidade do teste das microbolhas estáveis foram 81,4% e 85,7%, respectivamente. Conclusão: O estudo sugere que o teste das microbolhas estáveis feito no aspirado bucal é uma opção confiável ao fluido gástrico para a predição da síndrome do desconforto respiratório do recém-nascido.

Infección por citomegalovirus humano en neonatos de un hospital público de Mérida, Yucatán / Human cytomegalovirus infection in neonates from a public hospital in Mérida, Yucatán

Resumen Introducción: El citomegalovirus humano es reconocido como la causa más común de infección viral congénita, la cual puede darse como resultado de infección primaria, reinfección o reactivación en la mujer embarazada; además, puede ocasionar retraso en el desarrollo neuronal y pérdida auditiva sensoneural en el neonato. Objetivo: Identificar la infección por citomegalovirus humano en neonatos por PCR en tiempo real (PCR-TR) y cultivo celular. Método: Estudio observacional, longitudinal y retrospectivo con muestras de hisopado oral provenientes de 362 neonatos nacidos en un periodo de 10 meses en un hospital público de Mérida, Yucatán. Se realizó PCR-TR para la detección de citomegalovirus humano. Se obtuvo cultivo celular primario de fibroblastos a partir de tejido de prepucio humano para recuperar el virus. Se siguieron solo los casos positivos. Resultados: Se encontró 0.86 % de infección por citomegalovirus humano por PCR-TR. No se recuperó el virus en cultivo. En las visitas de seguimiento, la salud sensorial y el neurodesarrollo fueron adecuados. Conclusión: La prevalencia de infección por citomegalovirus humano en neonatos fue similar a la de reportes mundiales y solo pudo evidenciarse por PCR. La infección asintomática detectada entre las 12 a 24 horas del nacimiento no tuvo consecuencias a largo plazo.

Abstract Introduction: Human cytomegalovirus (HCMV) is recognized as the most common cause of congenital viral infection, which can occur as a result of primary infection, reinfection or infection reactivation in the pregnant woman and be the cause of delay in neuronal development and sensorineural hearing loss in the neonate. Objective: To identify CMVH infection in newborns by real-time polymerase chain reaction (RT-PCR) and cell culture. Method: Observational, cross-sectional, retrospective study with oral swab samples from 362 neonates born within a 10-month period in a public hospital of Mérida, Yucatán. RT-PCR was carried out for the detection of HCMV. Fibroblast primary cell culture was obtained from human foreskin tissue to isolate the virus. Only positive cases were followed. Results: A prevalence of HCMV infection of 0.86 % was found by RT-PCR. No virus was isolated with cell culture. In the follow-up visits, sensory health and neurodevelopment were adequate. Conclusion: The prevalence of HCMV infection is similar to that of worldwide reports, and only was detected by RT-PCR. Asymptomatic infection detected 12-14 h after birth had no long-term health consequences.

Teste do pezinho: condições materno-fetais que podem interferir no exame em recém-nascidos atendidos na unidade de terapia intensiva / Heel prick test: maternal-fetal conditions that may have an effect on the test results in newborns admitted to the intensive care unit

RESUMO Objetivo: Descrever as características do teste do pezinho dos neonatos atendidos na unidade de terapia intensiva de um hospital universitário, bem como verificar se existiam condições maternas e fetais que pudessem interferir no resultado desse exame. Métodos: Estudo retrospectivo longitudinal de abordagem quantitativa que avaliou 240 prontuários médicos. Os dados coletados foram submetidos à análise estatística descritiva. Resultados: Houve predomínio de gestantes com idades entre 20 a 34 anos, com Ensino Médio completo e que realizaram mais de seis consultas pré-natais. As intercorrências ou patologias maternas ocorreram em 60% das mães, e a maioria (67,5%) não apresentou nenhuma condição que pudesse interferir no resultado do teste do pezinho. A maioria dos neonatos era prematura e exibiu baixo peso ao nascimento. Cerca de 90% dos neonatos exibiram condições que poderiam influenciar no exame, principalmente prematuridade, nutrição parenteral e transfusão sanguínea. Dos 240 neonatos, 25% apresentaram resultado alterado no teste do pezinho, sobretudo para fibrose cística e hiperplasia adrenal congênita. Conclusão: Existem condições maternas e neonatais que podem interferir no teste do pezinho e, nesse sentido, sua investigação é imprescindível, visando direcionar ações que promovam a saúde materno-infantil e consolidem a triagem neonatal nessa população.

ABSTRACT Objective: To describe the characteristics of the heel prick test in newborns admitted to the intensive care unit of a university hospital as well as to determine whether maternal and fetal conditions could have affected the results of this test. Methods: Retrospective longitudinal study with a quantitative approach that evaluated 240 medical records. The data collected were analyzed by descriptive statistical analysis. Results: There was a predominance of pregnant women aged 20 to 34 years who had a complete secondary education and who had more than six prenatal care visits. Maternal complications or pathologies occurred in 60% of the mothers, and most (67.5%) did not present any condition that could have affected the heel prick test results. Most newborns were premature and exhibited low birth weight. Approximately 90% of newborns exhibited conditions that could have influenced the test, especially prematurity, parenteral nutrition and blood transfusion. Of the 240 newborns, 25% had abnormal heel prick test results, especially for cystic fibrosis and congenital adrenal hyperplasia. Conclusion: There are maternal and neonatal conditions that can affect heel prick test results, and therefore, their investigation is essential, aiming to guide measures that promote mother and child health and consolidate neonatal screening in this population.

Amplitude-integrated electroencephalography for neonatal seizure detection. An electrophysiological point of view / Electroencefalograma integrado por amplitud para la detección de convulsiones neonatales. Un punto de vista electrofisiológico

ABSTRACT Seizures in the newborn are associated with high morbidity and mortality, making their detection and treatment critical. Seizure activity in neonates is often clinically obscured, such that detection of seizures is particularly challenging. Amplitude-integrated EEG is a technique for simplified EEG monitoring that has found an increasing clinical application in neonatal intensive care. Its main value lies in the relative simplicity of interpretation, allowing nonspecialist members of the care team to engage in real-time detection of electrographic seizures. Nevertheless, to avoiding misdiagnosing rhythmic artifacts as seizures, it is necessary to recognize the electrophysiological ictal pattern in the conventional EEG trace available in current devices. The aim of this paper is to discuss the electrophysiological basis of the differentiation of epileptic seizures and extracranial artifacts to avoid misdiagnosis with amplitude-integrated EEG devices.

RESUMO Las convulsiones neonatales están asociadas a una alta morbi-mortalidad por lo que su correcto diagnóstico y tratamiento es fundamental. Las convulsiones en los recién nacidos son frecuentemente subclínicas lo que hace que su detección sea dificultosa. La electroencefalografía integrada por amplitud es una técnica de monitoreo electroencefalográfico simplificado que ha encontrado una creciente aplicación clínica en las unidades de terapia intensiva neonatales. Su principal ventaja es la relativa simplicidad de su interpretación lo que permite a personal no especializado del equipo neonatal diagnosticar convulsiones electrográficas en tiempo real. Sin embargo, para evitar diagnosticar erróneamente artefactos rítmicos como crisis epilépticas es necesario reconocer los patrones electrofisiológicos ictales en el EEG convencional disponible en los dispositivos actuales. El objetivo de este artículo es describir las bases electrofisiológicas para la diferenciación de convulsiones neonatales y artefactos extracraneanos para evitar errores diagnósticos con el uso de EEG integrado por amplitud.

Pênfigo neonatal em filho de mãe com pênfigo vulgar: relato de caso / Neonatal pemphigus in an infant born to a mother with pemphigus vulgaris: a case report

RESUMO Objetivo: Relatar um caso de pênfigo neonatal em paciente que manifestou lesões cutâneas extensas e críticas ao nascimento. Descrição do caso: Recém-nascido do sexo masculino com lesões vesicobolhosas extensas em região anterior do tórax e abdome, desde o nascimento. Admitido na ala pediátrica de um hospital para diagnóstico etiológico e tratamento. Com base na história materna e na avaliação clínica, concluiu tratar-se de pênfigo vulgar neonatal. O paciente apresentou evolução satisfatória, sem a necessidade de intervenção farmacológica. Comentários: Os casos descritos na literatura e as referências avaliadas revelam o pênfigo neonatal como uma doença de ocorrência rara, porém cujo conhecimento e diagnóstico precoce têm grande relevância clínica, considerando-se que geralmente se manifesta com lesões epidérmicas extensas e de aspecto crítico, embora apresente curso clínico transitório e benigno, sem necessidade de tratamento específico e sem relação com doença futura.

ABSTRACT Objective: To report on the case of a patient with neonatal pemphigus that had extensive and critical skin lesions at birth. Case description: A newborn male with extensive vesico-bullous lesions on the anterior side of his chest and abdomen at birth. He was admitted to the pediatric ward of a hospital for an etiological diagnosis and for treatment. Based on maternal history and a clinical evaluation, the patient was diagnosed with neonatal vulgar pemphigus. His progression was satisfactory and, in the end, he did not need pharmacological interventions. Comments: The cases reported in the literature and the references evaluated reveal that neonatal pemphigus is rare, but that knowledge about the disease allows for an early diagnosis to be made. This has great clinical relevance considering that the disease usually manifests itself in the form of extensive epidermal lesions, even though it is transient and benign, it does not require specific treatment, and it does not have any relation with possible future diseases.

Should arboviruses be the only diagnosis hypothesis in pregnant women in endemic areas presenting with a rash?

Abstract Listeria is an unusual pathogen that causes neonatal infection with high morbidity and mortality. We present the case of a premature newborn whose mother had a rash during pregnancy; the newborn had severe early sepsis because of Listeria monocytogenes and histopathologically suggestive findings of the placenta. Obstetricians and neonatologists should suspect listeriosis in cases with compatible epidemiological history, clinical features, and examination findings of the placenta.

Anquilobléfaron y el tratamiento a las anomalías congénitas palpebrales y del ojo / Ankyloblepharon and the treatment of congenital palpebral and ocular anomalies

El anquilobléfaron es la fusión parcial o total de los bordes palpebrales. En dependencia de la localización, este puede clasificarse como medial o interno y lateral o externo. Es una malformación congénita que constituye una condición muy infrecuente. Puede estar genéticamente determinada, aunque su causa exacta o mecanismo de producción no se conoce claramente. El primer caso corresponde a una lactante femenina, de 57 días de nacida, antecedentes de madre con paladar hendido ya operado. Al examen oftalmológico se constata en el ojo derecho fusión a nivel de todo el borde palpebral y en el izquierdo brida hacia sector temporal, además de presentar paladar hendido. El segundo caso, es una paciente femenina de 24 meses de edad, que en el examen ocular se observa brida que fusiona ambos bordes palpebrales del ojo izquierdo, en zona temporal. Se confirma diagnóstico de anquilobléfaron. En el primer caso se decide, por la edad, mantener una conducta expectante y posponer el tratamiento quirúrgico hasta que se realice la cirugía de la fisura labial, la cual se realiza a los 3 meses. En ambos casos la conducta fue quirúrgica, con buenos resultados estéticos y funcionales. El diagnóstico de esta anomalía es clínico y el examen físico minucioso, el cual, unido a los conocimientos del especialista sobre estas anomalías, juega un papel primordial. El tratamiento siempre es quirúrgico, el procedimiento a ejecutar es sencillo, incluso cuando requiere de reconstrucción palpebral(AU)

Ankyloblepharon is the partial or total fusion of eyelid margins. According to its location, it may be classified as medial or internal and lateral or external. This congenital malformation is a very rare condition. Though it may be genetically determined, its exact cause or development mechanism is not clearly known. The first case is a 57-day-old female infant whose mother had undergone cleft palate surgery. Ophthalmological examination revealed fusion of the entire eyelid margin of the right eye and bridling toward the temporal sector of the left eye, as well as a cleft palate. The second case is a 24-month-old female patient whose ophthalmological examination revealed bridling fusing the two eyelid margins of the left eye in the temporal zone. Ankyloblepharon diagnosis was confirmed. In the first case, due to the patient's age it was decided to postpone surgical treatment until lip fissure surgery was performed at 3 months. In both cases management was surgical, with good esthetic and functional results. Diagnosis of this condition is based on meticulous clinical and physical examination, supported by the decisive role played by the specialist's knowledge about these anomalies. Treatment is always surgical and the procedure to be performed is simple, even when palpebral reconstruction is required(AU)

Prevalence and characterization of neonatal skin disorders in the first 72 h of life / Prevalência e caracterização das afecções cutâneas neonatais nas primeiras 72 horas de vida

Abstract Objective: To determine the prevalence of neonatal dermatological findings and analyze whether there is an association between these findings and neonatal and pregnancy characteristics and seasonality. Methods: Newborns from three maternity hospitals in a Brazilian capital city were randomly selected to undergo dermatological assessment by dermatologists. Results: 2938 neonates aged up to three days of life were randomly selected, of whom 309 were excluded due to Intensive Care Unit admission. Of the 2530 assessed neonates, 49.6% were Caucasians, 50.5% were males, 57.6% were born by vaginal delivery, and 92.5% of the mothers received prenatal care. Some dermatological finding was observed in 95.8% of neonates; of these, 88.6% had transient neonatal skin conditions, 42.6% had congenital birthmarks, 26.8% had some benign neonatal pustulosis, 2% had lesions secondary to trauma (including scratches), 0.5% had skin malformations, and 0.1% had an infectious disease. The most prevalent dermatological findings were: lanugo, which was observed in 38.9% of the newborns, sebaceous hyperplasia (35%), dermal melanocytosis (24.61%), skin desquamation (23.3%), erythema toxicum neonatorum (23%), salmon patch (20.4%), skin erythema (19%), genital hyperpigmentation (18.4%), eyelid edema (17.4%), milia (17.3%), genital hypertrophy (12%), and skin xerosis (10.9%). Conclusions: Dermatological findings are frequent during the first days of life and some of them characterize the newborn's skin. Mixed-race newborns and those whose mothers had some gestational risk factor had more dermatological findings. The gestational age, newborn's ethnicity, gender, Apgar at the first and fifth minutes of life, type of delivery, and seasonality influenced the presence of specific neonatal dermatological findings.

Resumo Objetivo: Verificar a prevalência dos achados dermatológicos nos primeiros dias de vida e analisar se há associação com características neonatais, gestacionais e sazonalidade. Métodos: Recém-nascidos de três maternidades de uma capital brasileira foram selecionados aleatoriamente para serem submetidos ao exame dermatológico feito por dermatologistas. Resultados: Foram selecionados aleatoriamente 2.839 neonatos com até 72 horas de vida, 309 foram excluídos por terem sido admitidos em Unidade de Tratamento Intensivo. Dos 2.530 neonatos examinados, 49,6% eram da etnia branca e 50,5% do sexo masculino. Foi observado algum achado dermatológico em 95,8% dos recém-nascidos; desses, 88,6% tinham lesões cutâneas transitórias neonatais, 42,6% marca de nascimento, 26,8% pustulose benigna neonatal, 2% lesões secundárias ao trauma, 0,5% malformação cutânea e 0,1% doença infecciosa. O achado dermatológico mais frequente foi o lanugo, observado em 38,9% dos neonatos, seguido por hiperplasia de glândulas sebáceas (35%), melanocitose dérmica (24,6%), descamação da pele (23,3%), eritema tóxico neonatal (23%), mancha salmão (20,4%), eritema da pele (19%), hiperpigmentação da genitália (18,4%), edema palpebral (17,4%), cistos de mília (17,3%), hipertrofia da genitália (12%) e xerose cutânea (10,9%). Conclusões: Os achados dermatológicos são frequentemente identificados nos primeiros dias de vida e muitos deles caracterizam a pele do recém-nascido. Os neonatos pardos e aqueles cujas mães apresentavam algum fator de risco gestacional tiveram mais achados dermatológicos. A idade gestacional, a etnia do neonato, o gênero, o índice de Ápgar, o tipo de parto e a sazonalidade influenciaram na presença de manifestações cutâneas específicas.

Dientes natales: informe de un caso y revisión de la literatura / Natal teeth: report of a case and review of the literature

Cuando se encuentran dientes presentes al nacimiento es frecuente que los médicos pediatras interconsulten con el odontólogo, dichos dientes reciben el nombre de natales y neonatales de acuerdo con el momento en el cual hacen su aparición, si los dientes se encuentran presentes al nacimiento se les denomina natales y si aparecen durante el primer mes de vida se les llama neonatales. No es raro que los dientes natales y neonatales carezcan de raíz, y debido a su débil unión con eltejido gingival es posible que estos dientes puedan desalojarse y serbroncoaspirados o deglutidos por el menor durante la alimentación al seno materno. Si bien los dientes natales y neonatales no constituyen una entidad patológica per se, existen algunos síndromes genéticos que entre sus características se encuentran los dientes natales o neonatales.

When teeth are present at birth, pediatricians frequently seek the opinionof a dentist. These teeth are known as natal or neonatal depending onwhether they are present at birth or appear during the fi rst month oflife. It is not uncommon for natal and neonatal teeth to have no root,and due to their weak bond to the gingival tissue they can come looseand be breathed in or swallowed by the child during breast feeding.While natal and neonatal teeth are not a pathological entity per se,there are certain genetic syndromes whose features include natal orneonatal teeth.

Nutritional management and postoperative prognosis of newborns submitted to primary surgical repair of gastroschisis / Manejo nutricional e prognóstico pós-operatório do recém-nascido submetido à correção cirúrgica primária de gastrosquise

Abstract Objective Gastroschisis is a defect of the abdominal wall, resulting in congenital evisceration and requiring neonatal intensive care, early surgical correction, and parenteral nutrition. This study evaluated newborns with gastroschisis, seeking to associate nutritional characteristics with time of hospital stay. Methods This was a retrospective cohort study of 49 newborns undergoing primary repair of gastroschisis between January 1995 and December 2010. The newborns’ characteristics were described with emphasis on nutritional aspects, correlating them with length of hospital stay. Results The characteristics that influenced length of hospital stay were: (1) newborn small for gestational age (SGA); (2) use of antibiotics; (3) day of life when enteral feeding was started; (4) day of life when full diet was reached. SGA infants had longer length of hospital stay (24.2%) than other newborns. The length of hospital stay was increased by 2.1% for each additional day taken to introduce enteral feeding. However, slower onset of full enteral feeding acted as a protective factor, decreasing length of stay by 3.6%. The volume of waste drained by the stomach catheter in the 24 h prior the start of enteral feeding was not associated with the timing of diet introduction or length of hospital stay. Conclusion Early start of enteral feeding and small, gradual increase of volume can shorten the use of parenteral nutrition. This management strategy contributes to reduce the incidence of infection and length of hospital stay of newborns with gastroschisis.

Resumo Objetivo A gastrosquise é uma malformação da parede abdominal que resulta em evisceração congênita e requer tratamento intensivo neonatal, correção cirúrgica precoce e nutrição parenteral. Investigaram-se neste estudo os recém-nascidos com gastrosquise e procurou-se correlacionar as suas características nutricionais com o tempo da internação hospitalar. Métodos Estudo de coorte retrospectivo de 49 recém-nascidos submetidos à correção primária de gastrosquise de janeiro de 1995 a dezembro de 2010. As características dos neonatos foram descritas com ênfase nos aspectos nutricionais e relacionadas com o tempo de internação hospitalar. Resultados As características que influenciaram a duração da internação foram: 1) recém-nascidos pequenos para a idade gestacional (PIG); 2) uso de antibióticos; 3) dia de vida ao iniciar a dieta enteral; 4) dia de vida ao atingir a dieta plena. Recém-nascidos PIG tiveram maior tempo de internação (24,2%) do que demais neonatos. O tempo de internação foi aumentado em 2,1% para cada dia a mais que se demorou a introduzir a dieta enteral. Entretanto, atingir mais lentamente o aporte pleno da dieta enteral agiu como fator protetor, diminuiu 3,6% no tempo de internação. O volume de resíduo drenado pelo cateter gástrico, nas últimas 24 horas antes do início da dieta enteral, não apresentou correlação com o momento da introdução da dieta nem com a duração da hospitalização. Conclusão Iniciar a dieta enteral precocemente, com aumento gradativo em pequenos volumes, pode abreviar a duração da nutrição parenteral. Esse manejo contribui para a diminuição da incidência de infecções e do tempo de hospitalização de recém-nascidos com gastrosquise.

Modelo estadístico para predecir el puntaje de desarrollo psicomotor de niños de 4 a 5 años de edad en función del nivel socioeconómico: Proposal of a statistical model to predict the score of psychomotor development of children 4 to 5 years according to socioeconomic level / Proposal of a statistical model to predict the score of psychomotor development of children 4 to 5 years according to socioeconomic level

Introducción: estudios recientes enfatizan la importancia de examinar el efecto del nivel socioeconómico sobre el desarrollo psicomotor infantil, en tal sentido las investigaciones informan que el nivel económico y el ambiente sociocultural en que se desenvuelve el niño son fundamentales para favorecer un normal desarrollo en la infancia Objetivos: proponer un modelo estadístico para predecir el puntaje de desarrollo psicomotor de niños y niñas de 4 a 5 años de edad en función del nivel socioeconómico. Metodología: se evaluó el desarrollo psicomotor a una muestra de 228 niños y niñas por medio de la aplicación de la batería TEPSI. Para determinar el nivel socioeconómico se aplicó una encuesta sociodemográfica a los padres y apoderados. Se efectuó un análisis correlacional bivariado no paramétrico, además se realizaron pruebas ANOVA de un factor, finalmente para modelar se efectuó un análisis de regresión múltiple. Resultados: los resultados reportaron que el nivel educacional del jefe de hogar y el ingreso per cápita correlacionan significativamente con el desarrollo psicomotor. Conclusiones: en cuanto a los modelos, se informa que fue posible diseñar tres modelos. El primero permite predecir un 4,2% del puntaje en el desarrollo psicomotor en función de la variable ingreso per cápita. El segundo modelo es capaz de predecir en un 11% el puntaje del lenguaje en base al variable ingreso per cápita. Por último, el tercer modelo, con bajo valor predictor (2,2%), permite predecir el puntaje de la coordinación en función del nivel educacional del jefe de hogar.

Introduction: recent studies emphasize the importance of examining the effect of socioeconomic status on child psychomotor development. In this sense, research conducted reports that the level of economic and cultural environment child operate in, are crucial for facilitating their normal development. Objectives: the study proposes a statistical model to predict the psychomotor development score of children from 4 to 5 years of age depending on the socio-economic level. Methodology: psychomotor development was evaluated in a sample made up of 228 boys and girls through the application of the psychomotor development test (TEPSI). A demographic survey was applied to parents and guardians to determine their socio-economic level. A non-parametric bivariate correlational analysis was performed, and a single factor ANOVA tests were carried out. Last, a multiple regression analysis was made for modelling purposes. Results: the results reported that the educational level of the head of household and the per capita income is significantly correlated with the psychomotor development. Conclusions: as to models, the possibility of designing three models is reported. The first one allows predicting 4.2 % of the psychomotor development score based on the per capita income variable. The second model is able to predict 11% of the language score based on the per capita income variable. Last, the third model, with low predictive value (2.2 %), enables predicting the coordination score, based on the educational level of the head of household.

Lupus eritematoso neonatal: reporte de un caso / Neonatal lupus erythematosus: case report

El lupus eritematoso neonatal (LEN) es una enfermedad muy poco frecuente que se presenta en el recién nacido, dada por el pasaje transplacentario de autoanticuerpos anti Ro/SSA, anti La/SSB y U1-RNP. Las principales manifestaciones clínicas son dermatológicas y cardíacas, pudiendo además presentar manifestaciones hepáticas, hematológicas y/o neurológicas. Presentamos un caso clínico de un lactante de 3 meses al que se le realizó diagnóstico de LEN en base a la presencia de lesiones cutáneas y hallazgos histopatológicos e inmunológicos compatibles, no se acompañó de manifestaciones sistémicas y presentó una muy buena evolución posterior. El interés del caso es mostrar una patología poco frecuente que suele presentarse con lesiones cutáneas características, destacando que el pronóstico estará determinado por el compromiso cardíaco y que permite en muchos casos realizar diagnóstico materno de una enfermedad autoinmune asintomática.

Neonatal lupus erythematosus (LEN) is a rare disease that occurs in the newborn given by the transplacental passage of maternal Anti-Ro/SSA, Anti-La/SSB and Anti-U1-RNP autoantibodies. The main clinical manifestations are dermatologic and cardiac, it may also have hepatic, hematologic or/and neurological ones. The study reports a case of a three month infant who is diagnosed with LEN, based on the presence of consistent findings of skin lesions and histopathology and immunology compatible findings. In this case, it was not accompanied by systemic manifestations evolution was a favorable one. The case is relevant since it presents an unusual condition that is usually accompanied by characteristic skin lesions, where prognosis is determined by cardiac involvement. In many cases, this enables maternal diagnosis of an asymptomatic autoimmune disease.

Síndrome de artrogriposis, disfunción tubular renal y colestasis: causa de colestasis neonatal. A propósito de un caso / Arthrogryposis-renal tubular dysfunction-cholestasis syndrome: a cause of neonatal cholestasis. Case report

El síndrome de artrogriposis, disfunción tubular renal y colestasis es un trastorno fatal infrecuente que compromete múltiples aparatos y sistemas de órganos. Es un trastorno autosómico recesivo hereditario, causado por defectos en los genes VPS33B y VIPAR. Los tres signos primordiales de este síndrome son la artrogriposis, la disfunción tubular renal y la colestasis. Otros compromisos orgánicos a veces asociados con este síndrome son ictiosis, malformación del sistema nervioso central, anomalías trombocíticas, defectos cardíacos congénitos y grave retraso del crecimiento. Las manifestaciones clínicas, la biopsia de un órgano y los análisis de mutaciones pueden ayudar con el diagnóstico, pero no existe un tratamiento curativo; solamente puede instaurarse un tratamiento sintomático. Varios síntomas de esta afección usualmente se manifiestan en el período neonatal: artrogriposis, colestasis neonatal, lesiones cutáneas, entre otros. En general, la supervivencia se prolonga hasta el primer año de vida. Presentamos el caso de una recién nacida con una rápida evolución y desenlace fatal.

Arthrogryposis-renal dysfunction-cholestasis syndrome is a rare lethal disorder that involves multipl organ system. It is inherited autosomal recessive and caused by defects in the VPS33B and VIPAR genes. Three cardinal findings of this syndrome are arthrogryposis, renal tubular dysfunction and cholestasis.The other organ involvements including ichthyosis, central nervous system malformation, platelet anomalies, congenital heart defects and severe failure to thrive are sometimes associated with this syndrome. Clinical findings, organ biopsy and mutational analysis can help for diagnosing but there is no curative treatment except supportive care. Several symptoms of this condition are already usually present in the neonatal period: arthrogryposis, neonatal cholestasis, skin lesions, among others. Usually survival is until the first year of life. We present a newborn whose evolution was rapidly fatal.

Quality of antenatal care as a risk factor for early onset neonatal infections in Rio de Janeiro, Brazil

Background: Neonatal infection is a serious public health problem. The aim of this study was to assess the influence of the antenatal care on the risk of early-onset neonatal healthcare associated infection in two Brazilian maternities. Methods: Cohort study - Newborns admitted at two public neonatal intensive care units from 2008 to 2009 were included in the study. Data on antenatal and perinatal variables were collected from maternal prenatal cards and medical charts. Newborns were actively surveyed for early-onset neonatal healthcare associated infection, defined as a neonatal infection diagnosed within 48 h after birth. Multiple logistic regression was used to assess variables independently associated with early-onset neonatal healthcare associated infection. Results: 561 neonate-mother pairs were included in the study. Early-onset neonatal health-care associated infection was diagnosed in 283 neonates (51%), an incidence rate of 43.5/1000 live births. Neonates whose mothers had less then six antenatal visits were under risk significantly higher for early-onset neonatal healthcare associated infection (OR = 1.69, 95% CI = 1.11-2.57), after adjusting for birth weight, membranes ruptured for >18 h, maternal complications during delivery, maternal infection at admission, and hospital where patients received care. Conclusions: The risk of neonatal early-onset neonatal healthcare associated infection was significantly associated with insufficient number of antenatal care visits. Further studies assessing the quality of antenatal care and targeting its improvement are warranted. .
