    Full Text Available INTRODUCCIÓN. El diagnóstico microbiológico de la infección neonatal de inicio precoz es complejo. En la mayoría de los recién nacidos se inicia el tratamiento ante la sospecha clínica y la positividad de algunos reactantes de fase aguda y el hemograma. MÉTODOS. Se analizó el valor predictivo utilizando como método de referencia el hemocultivo periférico o el hallazgo anatomopatológico de infección de algunos exámenes de laboratorio clínico de forma aislada. El estudio se realizó en el total de los casos, 32 neonatos con infección de inicio precoz probada y probable, y por localización de la infección. RESULTADOS. Ni la proteína C-reactiva positiva ni las alteraciones de los leucocitos totales fueron buenos predictores de sepsis de inicio precoz de cualquier localización. La trombocitopenia impresionó ser un marcador competente pero no resultó así al calcular el intervalo de confianza al 95 %. Al excluir la localización pulmonar, la proteína C-reactiva positiva se convirtió en un marcador competente. Ninguno de los neonatos con infección pulmonar probada tuvo resultados positivos en los exámenes clínicos realizados. CONCLUSIONES. No se cuenta de momento con ninguna prueba de laboratorio clínico capaz de predecir con certeza la presencia de infección de inicio precoz de cualquier localización. La proteína C-reactiva cualitativa es un marcador competente de infección precoz del torrente sanguíneo y de meninges en los neonatos.INTRODUCTION: Microbiological diagnosis of neonatal infection of early onset is complex. In most of newborns diagnosis is started if there is a clinical suspicion and the positivity of some acute-phase reactants and the hemogran. METHODS: Prognostic value was analyzed using as reference method the peripheral hemoculture or the pathological anatomy findings of infection in some of clinical laboratory examinations in an isolated way. Study was performed in all the cases, in 32 neonates

Entre os fatores de risco para endocardite foram destacados o cateterismo venoso central, hemocultura com crescimento de Staphylococcus aureus e ventilação mecânica. O diagnóstico foi realizado no 61o dia de internação devido a presença de febre persistente e aparecimento de sopro cardíaco sistólico. O ecocardiograma mostrou trombo em átrio direito, medindo 1,9 x 0,7mm sendo realizada antibioticoterapia e ressecção cirúrgica, com melhora clínica. No 125° dia de internação ocorreu óbito devido à sepse e abscesso cerebral. Na necrópsia não foram observados malformações cardíacas. Os autores concluem ser de grande importância o conhecimento das complicações potenciais das técnicas invasivas utilizadas em recém-nascidos criticamente doentes. A suspeita clínica de endocardite deve ser realizada em todos os neonatos com sepse, internados em Unidade de Terapia Intensiva Neonatal por tempo prolongadoThe authors reported on a 11 day-old child, admitted in Neonatal Intensive Care Unit for multiple congenital malformations, who had sepsis and bacterial endocarditis. Among the risk factors for endocarditis were outstanding: the central venous catheterism, hemoculture with growth of Staphylococcus aureus and mechanical ventilation. The diagnosis was made in the 61st day after admission owing to the presence of persistent fever and appearance of systolic murmur. The echocardiogram revealed a thrombus in the right atrium measuring 1.9 x 0.7mm. Antibiotic therapy and surgical resection being performed, with clinical improvement.

    Full Text Available OBJECTIVE: To assess the contribution of neonatal electroencephalogram (EEG and its correlation with the neurological examination at age of 9 months in newborns with bacterial neonatal meningitis. METHOD: Twenty seven infants were studied with positive cerebrospinal fluid (CSF culture for bacteria. We used the worse EEG result during acute phase of meningitis, and performed neurologic follow-up after discharge from hospital. Background cerebral activity was classified as normal or mildly, moderately, or markedly abnormal. Neurologic examination outcomes was classified normal, mild abnormalities, moderate abnormalities and severe abnormalities. RESULTS: EEG performed in the neonatal period during acute bacterial meningitis predicts adverse outcome early at age of 9 months, and had a significant correlation with cephalic perimeter and active tone alterations. CONCLUSION: Neonatal EEG is useful for predicting abnormal outcomes, especially cephalic perimeter and active tone abnormalities at 9 months of age in infants with bacterial neonatal meningitis.OBJETIVO: Medir la contribución del electroencefalograma (EEG neonatal y su correlación con el examen neurológico a la edad de 9 meses en recién nacidos con meningitis neonatal bacteriana.

Se presenta agotamiento folicular, por dotación insuficiente de folículos o destrucción acelerada de los ovocitos. Las causas son varias, pero predominan las genéticas, autoinmunes y las iatrogénicas. Entre las causas genéticas, son frecuentes las deleciones Xq y Xp, las translocaciones, aberraciones numéricas (47,XXX, 45,X0, premutaciones de X frágil, entre otros. Entre las enfermedades autoinmunes son de importancia la insuficiencia poliglandular tipo I y II. Las iatrogenias pueden ser quirúrgicas en ovarios o trompas y, con la presencia del cáncer de mama en mujeres jóvenes, el tratamiento oncológico puede destruir las células germinales, por lo que hoy se sugiere utilizar técnicas de preservación de la función ovárica y de la fertilidad. En el manejo de la falla ovárica precoz, una vez determinada la causa, se sugiere el uso de terapia estrogénica, aunque no se ha hecho investigación en el tipo de hormona a utilizar, dosis y consecuencias a largo plazo. Tener presente la prevención y manejo de la osteoporosis y la enfermedad cardiovascular. Con relación a la infertilidad, se está realizando criopreservación de embriones y ovocitos para autodonación, así como criopreservación de tejido ovárico cortical para autotrasplante posterior, con éxitos y limitaciones. Los agonistas de GnRH podrían actuar en proteger los ovarios en casos de quimioterapia. Se observa con atención la terapia génica experimental en casos de falla ovárica precoz.

Se compararon 2 grupos de 23 recién nacidos críticos, uno de ellos recibió alimentación parenteral (grupo I y el otro no (grupo II. Se encontró homogeneidad en ambos grupos en cuanto a peso, edad gestacional, valoración nutricional al nacer, sexo y morbilidad inicial. La nutrición parenteral se caracterizó por su uso precoz (menos de 72 horas, conjuntamente con alimentación enteral mínima. La media del aporte máximo de macronutrientes fue de 16 g/kg/d de dextrosa, 1,2 g/kg/d de lípidos y 2 g/kg/d de proteínas. El desarrollo nutricional fue más favorable en el grupo con NP, porque le disminuyó a la mitad el tanto por ciento de peso perdido en la primera semana de vida, le sostuvo mayor aporte energético durante ese período y recupó 7 días antes su peso del nacimiento en relación con el grupo II. Las complicaciones fueron similares en ambos grupos, para concluir en que estas no estuvieron relacionadas con el uso de NP.A descriptive study was conducted at the Neonatal Intensive Therapy Service of "Ramón Gonzalez Coro" Gynecoobstetric Hospital, in Havana City, from January 2000, to January 2002, aimed at assessing the advantages of the use of early parenteral nutrition in the critically ill neonates during the first week of life. 2 groups of 23 critical newborn infants each were compared.

    Full Text Available A peritonite bacteriana espontânea ocorre em 30% dos cirróticos com ascite e, neste grupo, apresenta altas taxas de morbidade e mortalidade. Os fatores predisponentes incluem a diminuição da defesa imunológica encontrada no homem nas fases avançadas da cirrose, o supercrescimento da flora intestinal e a translocação bacteriana da luz dos intestinos aos linfonodos mesentéricos. As manifestações clínicas variam de graves a leves ou ausentes, sendo sempre necessária a análise do líquido ascítico. O diagnóstico de peritonite bacteriana espontânea se faz pela contagem de neutrófilos > 250/mm³ no líquido ascítico associado ou não ao crescimento de bactéria na cultura. As enterobactérias predominam como causa da infecção, sendo a Echerichia coli a bactéria mais freqüentemente isolada. O diagnóstico precoce e o tratamento adequado provocaram a queda das taxas de mortalidade nas duas últimas décadas. O uso endovenoso de cefalosporinas de terceira geração mostra-se eficaz em 70% a 95% dos casos. A recorrência de peritonite bacteriana espontânea é comum e pode ser prevenida com norfloxacina oral, de uso contínuo. O surgimento de resistência bacteriana tem estimulado a procura de novas opções para a profilaxia da peritonite bacteriana espontânea; os probióticos constituem nova abordagem promissora, mas que necessita melhor avaliação. Recomenda-se a profilaxia primária de curta duração aos cirróticos com ascite que apresentem episódio de hemorragia digestiva alta.

Objetivo: conocer cómo se procedió retrospectivamente con la indicación de tratamiento antibiótico en neonatos con pleocitosis del líquido cefalorraquídeo, antes de desarrollar el modelo mencionado, y fortalecer y fundamentar una estrategia del tratamiento antibiótico, basados en nuestro Modelo de Predicción de Meningitis Bacteriana Neonatal, ante un neonato con pleocitosis del líquido cefalorraquídeo. Métodos: estudio retrospectivo y aplicado, que incluyó 290 neonatos evaluados por probable infección, 44 con meningitis bacteriana y 246 con meningitis aséptica, ingresados en el Servicio de Neonatología del Hospital Pediátrico "Juan Manuel Márquez", entre febrero/1992 y diciembre/2009. Se verificó la efectividad del Modelo de Predicción de Meningitis Bacteriana Neonatal, lo que permitió clasificar los pacientes en alto o bajo riesgo de meningitis bacteriana. Se determinó retrospectivamente la indicación y los motivos de tratamiento antibiótico ante un neonato con pleocitosis del líquido cefalorraquídeo, así como análisis de asociación para distintas circunstancias clínicas, entre ellas, la clasificación de riesgo de infección bacteriana severa. Resultados: se precisó que el Modelo de Predicción de Meningitis Bacteriana Neonatal tuvo una sensibilidad y valor predictivo negativo de 100 % para meningitis bacteriana. Hubo concordancia estadísticamente significativa entre la predicción por el modelo y la clasificación de riesgo de infección bacteriana severa.

    Full Text Available El tabaquismo es una epidemia y en Chile la prevalencia no ha disminuido. Entre las causas más importantes de muerte por tabaquismo están el cáncer pulmonar y la enfermedad pulmonar obstructiva crónica (EPOC. La erradicación del tabaquismo es la mejor estrategia de prevención de estas enfermedades. La segunda estrategia es la detección precoz de ellas. Sin embargo la EPOC está sub diagnosticada en todo el mundo. No está claro si la solución es hacer más espirometrías en población de riesgo. Es posible que otros métodos diagnósticos como la tomografía axial computada de tórax (TAC y la difusión pulmonar, puedan mejorar la capacidad de diagnóstico precoz de esta enfermedad. El cáncer pulmonar es el más mortal de los cánceres. El diagnóstico en etapas tempranas mejora significativamente su pronóstico.

    Full Text Available Se describe la displasia de Mondini asociada a pérdida auditiva y meningitis bacteriana recurrente. La malformación de Mondini representa el 30 % de las anomalías congénitas del oído interno, puede ser unilateral o bilateral, y su principal característica consiste en el desarrollo coclear incompleto, causante de grados variables de hipoacusia neurosensorial. Se considera que la ocurrencia de esta malformación se produce por disrupción del desarrollo embrionario durante la séptima semana de gestación, en la cual se detiene el desarrollo coclear. Se presenta el caso de una niña de 12 años, atendida en los Servicios de Pediatría y Otorrinolaringología del Hospital Pediátrico Universitario "William Soler", por presentar 3 infecciones meningoencefálicas, en las cuales se aisló Streptococcus pneumoniae serotipo 19F, y se constató hipoacusia neurosensorial severa en el oído izquierdo. La tomografía axial computarizada de alta resolución del oído (cortes axiales y coronales, evidenció la malformación coclear y vestibular, con presencia de tejido en el oído medio que se comunicaba directamente con el oído interno del lado izquierdo a nivel de la ventana oval. Se destaca la importancia de la sospecha clínica de displasia de Mondini, y el impacto científico de la tomografía computarizada del hueso temporal, para el diagnóstico precoz de fístula congénita en el oído interno asociada a meningitis bacteriana recurrente.

    Full Text Available La resistencia bacteriana a los antibióticos es un problema de salud mundial que se encuentra en constante evolución. De manera frecuente se reportan nuevos mecanismos de resistencia bacteriana a los antibióticos, tanto en bacterias gram negativas como en gram positivas. La presencia de resistencia en una bacteria causante de infección disminuye las posibilidades de obtener la curación clínica y la erradicación bacteriológica e incrementa los costos del tratamiento, la morbilidad y la mortalidad; por lo que es importante seleccionar el tratamiento adecuado. Uno de los aspectos que más preocupa a los médicos en el diagnóstico y tratamiento de una infección es la llamada resistencia adquirida, la cual ocurre en una bacteria inicialmente sensible a los antibióticos, por cambios, mutaciones o la adquisición de genes de resistencia durante el fenómeno de transferencia genética lateral, proceso por medio del cual un organismo transfiere material genético a otra célula que no es descendiente. La resistencia bacteriana adquirida a los antibióticos puede ser de distintos tipos, dependiendo de la presión selectiva, las mutaciones o la transferencia de genes de resistencia. Las definiciones de resistencia se clasifican según el número y clase de antibióticos afectados. La multirresistencia (Multiple Drug Resistance, MDR se define como la ausencia de sensibilidad a, por lo menos, un fármaco en tres o más de las categorías de antibióticos; la resistencia extrema (Extensively Drug-Resistant, XDR se refiere a la ausencia de sensibilidad a, por lo menos, un agente en todas las categorías de antimicrobianos, excepto en dos de ellas o menos, y la resistencia a todos los antimicrobianos se define como resistencia a todas las categorías de antibióticos. (1 Los mecanismos de resistencia dependen del tipo de bacteria que los desarrollen. Las bacterias gram positivas que producen con más frecuencias infecciones en humanos y que por

    Full Text Available Se define Telarquia Precoz como la aparición del botón mamario antes de los ocho años en ausencia de otros signos de pubertad. En los primeros años de vida puede ser secundaria al fenómeno de la minipubertad, mientras que en la etapa escolar podría ocurrir debido a la interacción entre disruptores endocrinológicos y la obesidad. Una parte importante se mantiene estacionaria o revierte, mientras que un pequeño porcentaje puede evolucionar hacia la pubertad precoz. Se debe realizar una anamnesis y examen físico adecuado buscando otros signos puberales, una buena curva de crecimiento y puede complementarse con imágenes y con un seguimiento para intentar determinar aquellas pacientes que evolucionarán hacia la pubertad precoz.

    2003-01-01

    Full Text Available Fundamento: La mortalidad infantil, y sus componentes neonatal y postneonatal, son importantes indicadores de salud, lo cual justifica su análisis periódico incluso en países desarrollados donde sus tasas han descendido considerablemente. El objetivo de este estudio es describir las modificaciones registradas en dichas tasas en Andalucía en el último cuarto de siglo. Métodos: Se han calculado las tasas anuales de mortalidad infantil, neonatal precoz y tardía, así como post-neonatal en 1975- 1998. Mediante regresión de Poisson se han estimado los porcentajes anuales de cambio de las tasas en los dos intervalos de 1975-1986 y 1987-1998 así como en el periodo completo 1975-1998. Se ha analizado también la mortalidad proporcional por causas infecciosas, respiratorias, congénitas, afecciones originadas en el periodo perinatal y el resto de causas, así como la razón de tasas de mortalidad por afecciones originadas en el periodo perinatal y para el total de causas, en el quinquenio 1994-98 respecto al quinquenio 1975-79, en los periodos infantil, neonatal (precoz y tardío y postneonatal. Resultados: Los mayores descensos porcentuales se han producido en la mortalidad neonatal precoz (6,38% y tardía (4,6%. La razón de tasas de mortalidad por afecciones originadas en el periodo perinatal entre 1994-98 y 1975-79 es 10 para la mortalidad postneonatal mientras que es inferior a 1 para la mortalidad neonatal tardía (0,63, precoz (0,33 e infantil (0,30. Conclusiones: La mortalidad en los periodos infantil, neonatal precoz, tardío y post-neonatal ha descendido acusadamente entre 1975 y 1998. El riesgo de fallecer por afecciones originadas en el periodo perinatal de los niños con más de 4 semanas y menos de 1 año de vida (periodo postneonatal se ha multiplicado por diez entre 1975-79 y 1994-98.

    Full Text Available INTRODUCCIÓN. En el Hospital Ginecoobstétrico Docente «Ramón González Coro» no se ha estudiado la prevalencia de la anemia muy precoz de la prematuridad y los factores asociados a su aparición. Se decidió realizar esta investigación para dar respuesta a esta interrogante y proporcionar bases a las autoridades administrativas para el trazado de estrategias preventivas más eficaces, que reduzcan esta complicación y sus consecuencias. MÉTODOS. Se realizó un estudio prospectivo, de corte transversal, donde se incluyeron todos los recién nacidos (RN ≤ de 1 500 g nacidos antes de las 37 semanas y atendidos en el servicio de neonatología del hospital durante el año 2008. El universo de estudio estuvo constituido por 25 neonatos. Se determinó en cada uno la presencia o no de anemia muy precoz. Se determinó la prevalencia de esta enfermedad y los factores maternos, perinatales y posnatales asociados. RESULTADOS. Presentó anemia muy precoz el 52 % de los neonatos (13/25. La hemoglobina materna baja no se asoció a la anemia muy precoz (RP 0,62; IC 95 % 0,21-1,80. Ninguna variable perinatal se asoció a la anemia muy precoz, aunque se encontró que la prevalencia de esta enfermedad disminuye al aumentar la edad gestacional al nacer (tendencia lineal: X² 4,33; gl 1; p 0,037. Los RN con alguna morbilidad grave tuvieron 2,44 veces más probabilidad de presentar anemia muy precoz (RP 2,44; IC 95 % 1,01-5,87. La prevalencia de la anemia muy precoz se incrementó al aumentar los mililitros por kilogramo de peso de sangre extraída (tendencia lineal: X² 7,6195; gl 1; p 0,0058.

    2015-09-01

    Full Text Available Introducción: Importantes estudios como el EPISCAN ha puesto de manifiesto en España, el retraso diagnóstico de la EPOC y una elevada tasa de infradiagnóstico, encontrando que el 73% de los pacientes estaba sin diagnosticar y en la mayoría de los que se diagnosticaban ya se encontraban en estadios III y IV. Este retraso en el diagnóstico provoca una elevada morbilidad, así como un elevado coste asistencial. Por todo esto es necesario un diagnóstico precoz. Objetivos: Identificar pacientes de EPOC no diagnosticados, mediante un servicio de cribado de EPOC ofrecido por farmacias comunitarias. Material y métodos: Población de estudio: mayores de 40 años de ambos sexos, fumadores, exfumadores, y fumadores pasivos, que presentan signos o síntomas crónicos, y que en el cuestionario COPD-PS obtengan una puntuación ≥4. A los pacientes se les realizó la prueba de espiración forzada mediante el dispositivo portátil Vitalograph COPD-6. Si presentaba valores del cociente FEV1/FEV6 <0,75 se derivaba el paciente a su médico de familia para que se le realizase la espirometría convencional de confirmación. Resultados: Se encuestaron un total de 198 pacientes, 154 de ellos presentaban COPD-PS ≥4,38 (24,7% de ellos presentaron resultados del cociente FEV1/FEV6 <0,75. La prevalencia de posible EPOC en este estudio se ha estimado en un 19,2% de los pacientes encuestados. Conclusiones: El significativo porcentaje de pacientes a los se les ha detectado una posible EPOC, nos demuestra la utilidad de implantar servicios de cribado y detección precoz de EPOC en las farmacias comunitarias.

    Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

    Full Text Available From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary. At least one-half of infants with neonatal retinoblastoma have unilateral tumors when the diagnosis is made, typically the International Intraocular Retinoblastoma Classification (Murphree Group B or higher, but most germline mutation carriers will progress to bilateral involvement, typically Group A in the fellow eye. Neonatal leukokoria usually leads to the diagnosis in children without a family history of retinoblastoma, and a Group C tumor or higher is typical in the more advanced involved eye. Almost all infants with neonatal retinoblastoma have at least one eye with a tumor in proximity to the foveola, but the macula of the fellow eye is frequently spared. Consequently, loss of reading vision from both eyes is exceptional. A primary ectopic intracranial neuroblastic tumor known as trilateral retinoblastoma is no more common after neonatal than other retinoblastoma. For many reasons, neonatal retinoblastoma may be a challenge to eradicate, and the early age at diagnosis and relatively small tumors do not guarantee the preservation of both eyes of every involved child. Oncology nurses can be instrumental in contributing to better outcomes by ensuring that hereditary retinoblastoma survivors receive genetic counseling, by referring families of survivors to early screening programs when they are planning for a baby, and by providing psychological and practical support

    Introducción: Durante la pubertad se realiza una secuencia de eventos que llevarán al individuo a su madurez en el desarrollo físico, sexual y emocional. Este periodo incluye la aparición de características sexuales secundarias así como el crecimiento, desarrollo y maduración de los órganos sexuales primarios. Se considera que la pubertad es precoz (PP cuando el crecimiento mamario (telarquia ocurre antes de los 8 años de edad, el vello púbico (pubarquia, antes de los 9 años y la menarquia (primera menstruación, antes de los 10 años.

    Materiales y métodos: Se trata de un estudio retrospectivo sobre el análisis de las historias clínicas de 50 pacientes femeninas que consultaron por sospecha de pubertad precoz en tres instituciones de Cali, durante el periodo 2000-2003. El diagnóstico de PP de origen central se confirmó por la aparición de telarquia precoz y por la respuesta positiva a la prueba de estimulación con hormona liberadora de gonadotropinas (GHz. En el análisis estadístico se utilizó chi2 mediante análisis STATA EPI INFO.

    Resultados: Se trató de pacientes con escolaridad promedio tercero de primaria, principalmente de zona urbana, de estratos socioeconómicos 2-3. Las edades promedio fueron, a la consulta 7,8 años ±1,31 y al inicio de telarquia, 6,8±1,8 años. El 96% de las pacientes tenían telarquia prematura.

    Full Text Available RACIONAL: Em torno de 30% dos pacientes com cirrose hepática apresentam infecção bacteriana na admissão hospitalar ou a desenvolvem durante a mesma. As infecções bacterianas são responsáveis por até 25% das mortes nesta população de pacientes. OBJETIVO: Avaliar a prevalência de infecção bacteriana em uma população de pacientes cirróticos internados em hospital geral, bem como correlacionar sua presença com a etiologia alcoólica da hepatopatia, com o grau de comprometimento da função hepática e com a presença de hemorragia digestiva alta. PACIENTES E MÉTODOS: Foram avaliadas retrospectivamente 541 internações hospitalares consecutivas em 426 pacientes com cirrose hepática, internados no período de 1992 a 2000. A média de idade destes pacientes foi de 50,5 anos (15-95, sendo 71,2% do sexo masculino. Etiologia alcoólica da hepatopatia esteve presente em 35,4% dos pacientes. Alta ou óbito do paciente no período da internação hospitalar foi considerado como principal desfecho. O nível de significância considerado na análise estatística foi de 5%. RESULTADOS: As infecções bacterianas ocorreram em 25% dos cirróticos (135 episódios. Destas, as mais freqüentes foram: a infecção do trato urinário em 31,1%, a peritonite bacteriana espontânea em 25,9% e a broncopneumonia em 25,2%.

    Paediatric and particularly neonatal neurosonography still remains a mainstay of imaging the neonatal brain. It can be performed at the bedside without any need for sedation or specific monitoring. There are a number of neurologic conditions that significantly influence morbidity and mortality in neonates and infants related to the brain and the spinal cord; most of them can be addressed by ultrasonography (US). However, with the introduction of first CT and then MRI, neonatal neurosonography is increasingly considered just a basic first line technique that offers only orienting information and does not deliver much relevant information. This is partially caused by inferior US performance – either by restricted availability of modern equipment or by lack of specialized expertise in performing and reading neurosonographic scans. This essay tries to highlight the value and potential of US in the neonatal brain and briefly touching also on the spinal cord imaging. The common pathologies and their US appearance as well as typical indication and applications of neurosonography are listed. The review aims at encouraging paediatric radiologists to reorient there imaging algorithms and skills towards the potential of modern neurosonography, particularly in the view of efficacy, considering growing economic pressure, and the low invasiveness as well as the good availability of US that can easily be repeated any time at the bedside.

  19. Neonatal pain

    Walker, Suellen M

    2014-01-01

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    Full Text Available Introducción: se han desarrollado herramientas de predicción de meningitis bacteriana (MB en pacientes pediátricos, pero ellas no incluyen el período neonatal. Objetivo: diseñar y validar un modelo de predicción de MB en pacientes neonatales quienes presentan pleocitosis del líquido cefalorraquídeo (LCR al ser evaluados por variables clínicas y de laboratorio. Pacientes y método: estudio retrospectivo y analítico, que incluyó 320 pacientes neonatales evaluados por probable infección, en quienes se hizo el diagnóstico de meningitis, 45 con MB y 275 con meningitis aséptica, e ingresados en el Servicio de Neonatología del Hospital Pediátrico Universitario "Juan M. Márquez", entre Febrero de 1992 y Diciembre del 2009. Se creó un Modelo Predictivo de Meningitis Bacteriana, sobre la base de un conjunto de variables identificadas mediante procedimientos de análisis uni y multivariado. El modelo se diseñó a partir de una población «de derivación», y se contrastó en otro grupo, este "de validación". Resultados: las variables seleccionadas para integrar el modelo predictivo fueron: 1 Apariencia de estado tóxico-infeccioso, 2 Convulsiones en el transcurso de la enfermedad, 3 Tinción de Gram del LCR positiva, 4 Proporción de leucocitos polimorfonucleares en el LCR >80%, y 5 Glucorraquia <1.0 mMol/l. Con estas variables se alcanzaron sensibilidad y valor predictivo negativo de 100.0%. Con el modelo propuesto, en el grupo de derivación no hubo ningún paciente malclasificado con predicción negativa de MB pero portador de este tipo de infección. En el grupo de validación, el modelo tuvo un desempeño similar, lo cual lo acredita como un modelo de predicción validado internamente. Conclusiones: el modelo de predicción diseñado descansa en variables de evaluación rutinarias, y permitió identificar inequívocamente la totalidad de los pacientes neonatales con MB. Su empleo podría ser una herramienta útil en la toma de

    2015-05-01

    Full Text Available La hipertensión arterial pulmonar (HAP es una enfermedad crónica, que se caracteriza por el aumento de la resistencia vascular pulmonar (RVP a nivel de la arteriola pulmonar, que provoca una progresiva sobrecarga y posterior disfunción del ventrículo derecho (VD, que en etapas finales lleva a la insuficiencia cardiaca derecha, la cual sella su pronóstico. La HAP es más frecuente en mujeres jóvenes en plena edad productiva, siendo la supervivencia media de 2-3 años, antes de la aparición de terapias específicas. La base genética sugiere una herencia autosómica dominante con penetrancia incompleta, reconociéndose principalmente la afección del BMPR2. En la etiopatogenia se reconoce una alteración en las señales que controlan fundamentalmente el equilibrio vasocontrictor-vasodilatador a nivel del endotelio, con un desbalance hacia la proliferación y vasoconstricción, en las que están involucradas 3 vías patogénicas: La del Óxido nítrico (ON, de la Prostaciclina (PG y de la Endotelina (ET. El diagnóstico precoz de la HAP se asocia con una mejor supervivencia a largo plazo, por lo que su búsqueda ante un paciente con disnea, fatiga, dolor torácico y/o síncopes, así como en las poblaciones en riesgo, como son familiares en 1° con HAP, Esclerodermia y portadores de Hipertensión Portal, debería ser la estrategia de elección. La Ecocardiografía Doppler (ECO es la herramienta de pesquisa más utilizada en la práctica clínica actual. El diagnóstico debe ser confirmado mediante un cateterismo derecho, con mediciones directas de la presión arterial pulmonar, y debe realizarse prueba de vasoreactividad. El advenimiento de los tratamientos farmacológicos-HAP específicos ha provocado un cambio en la evolución natural de la enfermedad, existiendo hoy terapias orientadas a controlar las principales vías patogénicas involucradas: ON, PG, y ET.

    Full Text Available O presente estudo teve como objetivos, avaliar o uso da orbifloxacina nas cistites bacterianas de felinos, e seus possíveis efeitos colaterais, mormente a nefro e/ou hepatotoxicidade. Para tanto, foram colhidas amostras de urina de 53 gatos com históricos variados, mas com predisposição à infecção urinária. A cistite bacteriana foi comprovada, através de exame microbiológico, em 13 pacientes. No entanto, apenas 10 apresentaram infecção por agentes sensíveis a orbifloxacina. Esses 10 pacientes foram então submetidos ao tratamento com orbifloxacina na dose de 2,5mg kg-1 a cada 24 horas por 10 dias. Não houve crescimento bacteriano nas amostras de urina submetidas à cultura, 72 horas após a interrupção do tratamento. Não foram observados sinais de nefro e/ou hepatotoxicidade nesses pacientes, uma vez que os níveis séricos de alanina aminotransferase (ALT, aspartato aminotransferase (AST, fosfatase alcalina (FA, albumina, uréia e creatinina não tiveram variação significativa após o uso do fármaco. Portanto, os resultados apresentados sugerem que a orbifloxacina pode ser usada como agente antimicrobiano nas infecções urinárias de felinos.

    Full Text Available In Western developed countries, Listeria monocytogenes is not an uncommon pathogen in neonates. However, neonatal listeriosis has rarely been reported in Taiwan. We describe two cases collected from a single medical institute between 1990 and 2005. Case 1 was a male premature baby weighing 1558 g with a gestational age of 31 weeks whose mother had fever with chills 3 days prior to delivery. Generalized maculopapular rash was found after delivery and subtle seizure developed. Both blood and cerebrospinal fluid culture collected on the 1st day yielded L. monocytogenes. In addition, he had ventriculitis complicated with hydrocephalus. Neurologic development was normal over 1 year of follow-up after ventriculoperitoneal shunt operation. Case 2 was a 28-weeks' gestation male premature baby weighing 1180 g. Endotracheal intubation and ventilator support were provided after delivery due to respiratory distress. Blood culture yielded L. monocyto-genes. Cerebrospinal fluid showed pleocytosis but the culture was negative. Brain ultrasonography showed ventriculitis. Sudden deterioration with cyanosis and bradycardia developed on the 8th day and he died on the same day. Neonatal listeriosis is uncommon in Taiwan, but has significant mortality and morbidity. Early diagnosis of perinatal infection relies on high index of suspicion in perinatal health care professionals. [J Formos Med Assoc 2007;106(2:161-164

    DEFINICIÓN DE LA RESISTENCIA

    De acuerdo al COC (Centro de Control de Enfermedades de Estados Unidos, la resistencia se da cuando un medicamento deja de inhibir el crecimiento o matar un microorganismo. 

    Hay dos tipos de resistencia la adquirida y la clínica. La adquirida se realiza en el laboratorio a través de las mutaciones o por transferencia de genes, sistemas de conjugación, transducción y transformación.

    La resistencia clínica es la observada en la práctica médica, donde no todos los organismos son igualmente sensibles o resistentes a cierto antibiótico y que requiere la ayuda de técnicas de laboratorio para medir cuantitativamente o cualitativamente dicho proceso.

    MECANISMOS DE LA RESISTENCIA BACTERIANA

    En la detección de la Resistencia Bacteriana se han identificado diferentes mecanismos utilizados por las bacterias: destrucción o inactivación enzimática, cambios en la permeabilidad de la membrana interna, alteraciones de los precursores de la pared celular, de la membrana y de los ribosomas.

    Para los años 90 se dispuso de una serie de antimicrobianos como betalactámicos, aminoglucósidos, macrólidos, sulfonamidas, trimetoprim, cloranfenicol, glicopéptidos, rifampicina, quinolonas, tetraciclinas....

    Full Text Available RESUMO A cadeia produtiva do Caiman yacare tem-se destacado no Mato Grosso com a exportação de 143.386 peles em 2015, cujo sistema de manejo (ranching implica a incubação artificial dos ovos. Nesse processo, a contaminação bacteriana de ovos influencia a taxa de eclosão. O conhecimento da microbiota de ovos incubados naturalmente orienta o manejo sanitário adequado no incubatório. No presente estudo, são apresentadas informações sobre essa microbiota e sua correlação com a de outros crocodilianos, apontando-se as espécies com potencial patogênico. Amostras de 20 ninhos de C. yacare foram coletadas e semeadas em ágar sangue e ágar Mac Conckey. A colônia condizente com Salmonella sp. foi confirmada pela técnica de reação em cadeia de polimerase. Das 22 espécies bacterianas isoladas, 59% pertencem à família Enterobacteriaceae e 41% a outros táxons bacterianos. A semelhança dos achados com as bactérias isoladas na microbiota oral e/ou intestinal/cloacal de crocodilianos foi de 77,27%. As bactérias mais e menos frequentes foram, respectivamente, Bacillus cereus, Flavobacterium multivorum, Citrobacter freundii, Escherichia hermannii, Hafnia alvei, Morganella, morganni, Salmonella sp., Serratia marcescens e Shigella sonnei. Das bactérias isoladas, 86,36% têm potencial patogênico para crocodilianos. A origem materna e a ambiental da microbiota de ovos incubados naturalmente são, respectivamente, de 77,27% e 27,27%.

    2010-02-01

    Hypoglycemia in the newborn may be associated with both acute decompensation and long-term neuronal loss. Studies of the cause of hypoglycemic brain damage and the relationship of hypoglycemia to disorders associated with hyperinsulinism have aided in our understanding of this common clinical finding. A recent consensus workshop concluded that there has been little progress toward a precise numerical definition of neonatal hypoglycemia. Nonetheless, newer brain imaging modalities have provided insight into the relationship between neuronal energy deficiency and central nervous system damage. Laboratory studies have begun to reveal the mechanism of hypoglycemic damage. In addition, there is new information about hyperinsulinemic hypoglycemia of genetic, environmental, and iatrogenic origin. The quantitative definition of hypoglycemia in the newborn remains elusive because it is a surrogate marker for central nervous system energy deficiency. Nonetheless, the recognition that hyperinsulinemic hypoglycemia, which produces profound central nervous system energy deficiency, is most likely to lead to long-term central nervous system damage, has altered management of children with hypoglycemia. In addition, imaging studies on neonates and laboratory evaluation in animal models have provided insight into the mechanism of neuronal damage.

Nuestro objetivo fue evaluar la eficacia inmediata, a la semana y al mes del uso controlado de cinco productos con estos componentes, comparados con otros productos de uso habitual. Se incluyeron 32 hogares de clase media de la Ciudad de Buenos Aires y la periferia en un estudio con intervención, abierto, aleatorizado, y de grupos paralelos, durante 6 meses. La mitad de los hogares fue seleccionada para usar hipoclorito de sodio, sales de amonio cuaternario y triclosán en la cocina y el baño durante un mes. El grupo control mantuvo prácticas habituales de limpieza doméstica. Se tomaron muestras para recuento y tipificación bacteriana de los sitios estudiados: muestras basales (sin discriminación de grupo en cocina, que presentaron recuento bacteriano promedio de 66.0 UFC/cm²; baño: 40.1 UFC/cm². Las muestras inmediatas a la limpieza (sin discriminación de grupo: en cocina: 0.8 UFC/cm²; baño: <1 UFC/cm². A la semana (grupo intervenido vs. grupo control: cocina 18.0 vs. 32.5 UFC/cm²; baño 12.7 vs. 7.7 UFC/cm². Al mes (intervenido vs. control: cocina: 60.1 vs. 62.1 UFC/cm²; baño: 37.0 vs. 42.0 UFC/cm². Se observó una notable disminución de la carga bacteriana en ambos grupos, lo que sugiere que no sólo la calidad de los productos sino también la educación en el uso desempeñan un papel clave en la desinfección del hogar. Este enfoque podría ser una herramienta importante para prevenir infecciones transmitidas por alimentos, dado que los coliformes fecales predominaron ampliamente en todas las muestras tipificadas.

    Full Text Available ARTÍCULO DE OPINIÓN. En nuestra cultura occidental tenemos un concepto triunfalista y mesiánico de la ciencia, ya que se confía que tarde o temprano la misma hallará respuestas y soluciones a los problemas del hombre. Sin embargo, la ciencia tiende a negar sistemáti-camente todo aquello para lo cual no tiene explicación y condena al olvido a todo conocimiento para lo cual no tiene aplicación actual. Las bacterias persistentes son uno de esos problemas olvidados, que recientemente ha despertado interés en la comunidad científica, al tener que enfrentarse a la problemática creciente de la resistencia bacteriana. Este artículo trata dos temas disímiles pero que están estrechamente relacionados. El primero, consiste en explicar el ignorado y olvidado fenómeno de la persistencia bacteriana y su impli-cancia en la progresiva disminución de la vida útil de los antibióticos. El segundo, es un análisis epistémico-ético con el objetivo de dilucidar la responsabilidad de la ciencia respecto de la ignorancia y el olvido de esta problemática. Finalmente se propone una pos-tura epistemológica para la revalorización constante de los conocimientos olvidados. SUMMARY. Bacterial persistence: an ignored problem by a science without answers. In our western culture, we have a triumphalist and messianic conception of science, since it is confided that sooner or later it will find the answers and the solutions to the problems of humanity. However, science tends to systematically ignore everything for which it has no explanation, and condemns to oblivion all knowledge that has not practical application. Persister cells are one of those forgotten problems, although it has recently attracted the attention of the scientific community, as it is associated with the growing problem of bacterial resistance. This article addresses two dissimilar but closely related topics. The first is to explain the forgotten and ignored phenomenon of persister cells

    2009-12-01

    Despite advances in the care of infants, there remain many newborns whose medical conditions are incompatible with sustained life. At times, healthcare providers and parents may agree that prolonging life is not an appropriate goal of care, and they may redirect treatment to alleviate suffering. While pediatric palliative treatment protocols are gaining greater acceptance, there remain some children whose suffering is unrelenting despite maximal efforts. Due to the realization that some infants suffer unbearably (ie, the burdens of suffering outweigh the benefits of life), the Dutch have developed a protocol for euthanizing these newborns. In this review, I examine the ethical aspects of 6 forms of end of life care, explain the ethical arguments in support of euthanasia, review the history and verbiage of the United States regulations governing limiting and withdrawing life-prolonging interventions in infants, describe the 3 categories of neonates for whom the Dutch provide euthanasia, review the published analyses of the Dutch protocol, and finally present some practical considerations should some form of euthanasia ever be deemed appropriate.

K+ is the most important intracellular cation and normal serum K+ is stabilized between 3.5 and 5.5 mEq/L. Hypokalemia may be caused by increased renal losses, increased extrarenal (gastrointestinal losses, redistribution or prolonged insufficient K+ intake. Clinical signs and symptoms occur as the result of functional changes in striated muscle, smooth muscle, and the heart. Hypokalemia is usually asymptomatic when K+ levels are between 3.0 and 3.5 mEq/L; however, there may sometimes be slight muscle weakness. Moderate hypokalemia is observed when serum K+ is between 2.5 and 3.0 mEq/L. Proximal muscle weakness is observed most commonly in lower extremities; cranial muscles are normal, but constipation and distention are prominent. Severe hypokalemia develops when serum K+ falls below 2.5 mEq/L. Rhabdomyolysis, myoglobinuria, severe muscle weakness, paralysis, respiratory distress, and respiratory arrest are observed. The clinical signs and symptoms may be unremarkable in cases of chronically developing hypokalemia; however, appropriate treatment is essential when serum K+ level falls below 2.5 mEq/L as the most dangerous complication of hypokalemia is fatal cardiac arrythmia, and changes visible with electrocardiography may not always correlate with the level of hypokalemia. Sodium (Na+, K+, chloride (Cl-, bicarbonate, creatinine, blood sugar, magnesium (Mg, plasma renin activity, aldosterone, and blood gases should be investigated by laboratory testing.

En Chile, la mortalidad por cáncer de próstata ha ido en aumento durante los últimos años, alcanzando una tasa de 20.9 por 100000 en el año 2009 y ocupa el segundo lugar en las causas de muerte por cáncer en el hombre.Las herramientas con que se dispone para detectar precozmente la enfermedad son el tacto rectal (TR y el antígeno prostático específico (APE, pero en el último tiempo se han estudiado una serie de nuevos marcadores como el PCA3, el pro-APE, TMPRSS2-ERG, 4K Score, SelectMDx®, ConfirmMDx® y ExoDx®. Algunos ya se encuentran en una fase inicial de uso clínico y pretenden aumentar la especificidad, especialmente en el diagnóstico de tumores más agresivos.Existe suficiente evidencia que la detección precoz de cáncer de próstata disminuye la mortalidad, ya que se cuenta con tratamiento efectivos para la enfermedad diagnosticada en etapas tempranas. El desafío está en encontrar nuevos marcadores que permitan identificar aquellos hombres que se encuentren en mayor riesgo, evitando así procedimientos innecesarios.

    The clinical examination of the CNS in the neonate is often difficult in cases of complex pathology. Diagnostic imaging of the neonatal brain has become extremely useful and in the last decade has developed in two main directions: CT and US. MR imaging has been used recently with varying success in the diagnosis of pathology in the neonatal brain. Despite technical difficulties, this imaging method is likely to become increasingly important in the neonate. The paper examines the normal neonatal brain anatomy as seen with the different modalities, followed by pathologic conditions. Attention is directed to the common pathology, in asphyxiated newborns, the patholphysiology of intraventicular hemorrhage and periventricular leukomalacia in the preterm neonate, and hypoxic-ischemic brain injury in the term neonate. Pitfalls, artifacts, and problems in image interpretation are illustrated. Finally, the subsequent appearance of neonatal pathology later in infancy and childhood is discussed

    Full Text Available RESUMEN El caracol Pala, Strombus gigas (Strombidae, es de gran importancia ecológica y socioeconómica en el área caribeña colombiana. Sin embargo, es una especie catalogada como “vulnerable” y existe muy poca información referente a las especies bacterianas asociadas al caracol que puedan ser importantes para el desarrollo, manejo productivo y de seguridad acuícola de estos gastrópodos. En este trabajo, nosotros empleamos un estudio microbiológico y molecular de la región intergénica entre los genes 16S y 23S rDNA, análisis del gen rDNA 16S y secuenciación, para analizar las bacterias asociadas al caracol Pala (S. gigas. La composición de bacterias cultivables asociadas fue evaluada por su capacidad para crecer en agar marino y en medios de cultivos selectivos. De un total de 28 muestras analizadas encontramos que el número de bacterias cultivadas en condiciones aerobias fue de alrededor 106 ufc mL-1 donde las bacterias pertenecientes a la familia Vibrionacea fueron las más abundantes, cerca de >105 ufc mL-1 . El análisis molecular de la región intergénica entre los genes 16S y 23S rDNA de las diferentes muestras, reveló una gran complejidad bacteriana asociada a S. gigas. Las secuencias de los amplificados del gen rDNA 16S identificó Pseudoalteromonas sp., Halomonas sp., Psycrobacter sp., Cobetia sp., Pseudomonas sp. y Vibrios sp. Nuestros resultados podrían sugerir un rol importante de estas bacterias como componentes de la comunidad asociada al S. gigas. Esta información puede complementar los estudios que se están implementando en los procesos para la conservación y repoblamiento de las poblaciones de S. gigas en Colombia. Palabras clave: Strombus gigas, Caracol pala, Bacteria, Región intergénica 16S-23S, rDNA 16S.

  4. Una nueva ultraestructura de ópalo CT en silcretas. Posible indicador de influencia bacteriana

    Bustillo, Mª A.

    1995-04-01

    Full Text Available Electron microscope observations of opaline silcretes found in the playa of a Miocene shallow lake reveal new opal CT microstructures. These microstructures are made up of fibres, filaments or rods, which are formed, in tum by coalesced microspheres or microhemispheres (0,1-0,2 µ diameter. They are up to 10 µ in length although larger ones could exist. They are straight, bent, wavy or even hairpin shaped. These microstructures comprise part of the opaline mass of the silcretes and are very similar to both neogenic opaline structures which are formed by bacterial intluence and to silicified biofilms. Therefore microbial mediation could exist in the genesis of this opal CT, although a possible inorganic origin by silicification of sepiolite is also considered.Un estudio mediante MEB de silcretas miocenas opalinas formadas por silicificación de playas en un ambiente de «playa-lake» pone de manifiesto la existencia de una nueva microestructura de ópalo CT. Esta microestructura denominada en general fibrosa, se manifiesta por la presencia de multitud de fibras, filamentos o varillas formadas por la alineación de microesferas o microhemisferas que presentan un diámetro entre 0,1 y 0,2 µ. Las fibras, filamentos o varillas tienen formas variables: rectas, curvadas, onduladas y «en horquilla», y presentan longitudes de hasta 10 µ, aunque podrían existir longitudes mayores. La disposición organizada de las microesferas en filamentos o fibras, constituyendo la masa general del ópalo, y su parecido con microestructuras opalinas que han sido formadas por influencia bacteriana, hacen considerar esta hipótesis, aunque no se puede descartar totalmente un origen inorgánico por silicificación de sepiolita.

    Full Text Available OBJETIVO: Análise prospectiva de fatores de prognóstico para complicações neurológicas da meningite bacteriana infantil. MÉTODOS: Este estudo prospectivo recrutou 77 crianças de um mês a 16 anos de idade tratadas de meningite bacteriana durante o período de 1/1/2009 a 31/12/2010. Foram escolhidos 16 preditores relevantes para analisar sua associação com a incidência de complicações neurológicas. Valores P abaixo de 0,05 foram considerados estatisticamente significativos. RESULTADOS: Das 77 crianças tratadas para meningite bacteriana, desenvolveram-se complicações neurológicas em 33 pacientes (43%, e duas crianças morreram (2,6%. A etiologia dos casos de meningite bacteriana foi comprovada em 57/77 (74% dos casos: foram encontrados 32 isolados de meningococos; 8 de pneumococos; 6 de bacilos gram-negativos; 5 de H. influenzae; 5 de estafilococos e 1 de S. viridans. Os fatores que se mostraram associados a aumento do risco de desenvolvimento de complicações neurológicas foram idade 5.000 células/mm³, pleiocitose > 5.000 células/mm³ depois de 48 horas, baixa relação da glicose no LCS/sangue 48 horas, presença de comorbidade e foco primário de infecção não se associaram a aumento do risco para o desenvolvimento de complicações neurológicas. CONCLUSÃO: Idade inferior a 12 meses e gravidade da apresentação clínica na admissão foram identificadas como os preditores mais fortes de complicações neurológicas e podem ter valor para selecionar pacientes para tratamento mais intensivo.

    Full Text Available Fundamentos: El indicador Años Potenciales de Vida Perdidos (APVP ha sido utilizado con frecuencia en análisis de mortalidad precoz, y recientemente ha servido para estimar el impacto de la última pandemia de gripe A(H1N1 pdm09. El objetivo de este estudio ha sido estimar los excesos de defunciones por gripe y neumonía (GyN en España y los APVP durante el periodo 1980-2008, valorando la mortalidad atribuible a gripe en función del tipo/subtipo de virus predominante. Métodos: Los excesos de defunciones mensuales se calcularon con modelos de regresión cíclica. El cálculo de APVP se realizó como el producto del número de excesos de defunciones por la diferencia entre la esperanza de vida al nacer y los años vividos para cada grupo de edad. El análisis de la variación entre los excesos de defunciones por GyN y APVP, según el tipo/subtipo de virus de la gripe predominante, se llevó a cabo con un análisis de regresión de Poisson. Resultados: En las temporadas con predominio del virus de la gripe A(H3 el promedio de excesos de defunciones por GyN se estimó en 1.348 y de APVP en 5.297, mientras que en las temporadas con predominio de A(H1 o B el promedio de excesos por las mismas causas fue de 648 y de APVP de 2.885. Las razones de tasas ajustadas de excesos (2,11; IC-95%=2,05-2,16 y de APVP (1,86; IC-95%=1,83-1,88 señalaron que las frecuencias relativas de ambos indicadores son significativamente mayores en las temporadas con predominio de virus de la gripe A(H3. Conclusiones: Los excesos de defunciones y APVP se duplicaron al comparar las temporadas con predominio del subtipo A(H3 frente al resto de virus de la gripe.

Por ejemplo, se ha descrito una importante correlación entre Clostridium septicum y carcinoma de colon, y se han visto relacionadas con leucemias y linfomas a especies que aparecen casi siempre como contaminantes (Bacillus spp., Corynebacterium spp. y a otras raramente aisladas en otros contextos (Capnocytophaga spp.. Hay bacterias que se aíslan casi exclusivamente de pacientes con sida (Rhodococcus equi. Se ha observado una mayor frecuencia de infecciones por Campylobacter spp., Aeromonas spp. y estreptococos del grupo G y del grupo mitis en individuos con algún tipo de cáncer que en el resto de los pacientes. También hay bacterias que son marcadoras de algún cáncer no detectado o que afectan más a pacientes neutropénicos que a individuos normoinmunes. La alteración de la reacción inflamatoria, la linfoproliferación mediada por antígenos bacterianos y la inducción de hormonas que aumentan la proliferación de las células epiteliales podrían ser causas de la oncogénesis bacteriana. Los ejemplos clásicos son el adenocarcinoma gástrico inducido por Helicobacter pylori, la asociación de la bacteriemia por estreptococos del grupo bovis y el cáncer de colon y los linfomas de tejido linfoide asociado a mucosas (MALT en vinculación con especies de Helicobacter (MALT gástricos y con Chlamydophila spp. (MALT oculares.

Múltiples casos de agrandamientos gingivales están asociados a la ingesta de Fenitoína. El tratamiento de los agrandamientos gingivales inducidos por drogas por lo general es quirúrgico, pero mantener un buen control de placa bacteriana puede evitar en muchos casos que se presente un exagerado aumento de volumen gingival. Se presenta un caso de agrandamiento gingival en paciente masculino de 22 años de edad, bajo tratamiento antiepiléptico con fenitoína. Al examen clínico se observó aumento del volumen gingival de forma generalizada, en maxilar superior e inferior, predominante en sector anterior, produciendo ardor y sangrado durante el cepillado y la ingestión de alimentos. Al sondaje presenta múltiples pseudobolsas en los diferentes cuadrantes. La radiografía panorámica reveló pérdida ósea moderada horizontal, predominante en el sector posterosuperior, posteroinferior y anteroinferior.

    Full Text Available El diagnóstico precoz de la enfermedad de Alzheimer presenta importantes problemas bioéticos. Entre la detección temprana de la enfermedad y la aparición de sus síntomas media un período de tiempo en el cual la autonomía, la intimidad y la dignidad de quien la sufre pueden verse lesionadas por las eventuales medidas de apoyo y atención sanitaria o familiar que se decida adoptar. Éstas pueden terminar por transformar al paciente en un objeto de cuidado, impidiéndole asumir la enfermedad, elaborar la identidad y reordenar el espacio vital. Debe procurarse entonces que el cuidar no se traduzca en un asedio compasivo y un efecto invasivo que lleve a la anulación del paciente con Alzheimer.

Using membership and activity in the Church of Jesus Christ of Latter-day Saints (LDS or Mormon) as a proxy for parental health practices, i.e., tobacco and alcohol abstinence, differential neonatal mortality rates were calculated. The influence of potential confounding factors was evaluated. Low activity LDS members were found to have an excess risk of neonatal death five times greater than high activity LDS, with an upper bound of a two-sided 95% confidence interval of 7.9. The data consistently indicate a lower neonatal mortality rate for active LDS members. Non-LDS were found to have a lower rate than either medium or low activity LDS.

    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    Full Text Available La División de Vacunas e Inmunización de la Organización Panamericana de la Salud (OPS está promoviendo la vigilancia epidemiológica de neumonías bacterianas en niños latinoamericanos, con el objetivo de generar pruebas científicas que sustenten futuras decisiones de control mediante vacunas en los países de la Región. Como es poco frecuente que el diagnóstico de estas enfermedades abarque la documentación bacteriológica del agente causal, los estudios de este tipo que se realizan en el mundo aceptan la imagen radiológica de consolidación alveolar como criterio confirmatorio de una neumonía presuntamente bacteriana. En este informe se examinan la racionalidad teórica y los requisitos necesarios para utilizar la radiología de tórax como instrumento para la vigilancia epidemiológica de neumonías bacterianas. Además, se ofrece un resumen de las actividades realizadas en dos años de trabajo conjunto entre el Centro para Vacunas en Desarrollo, en Chile, y la División de Vacunas e Inmunización de la OPS. Durante ese período se fomentó el estudio epidemiológico de las neumonías bacterianas en niños latinoamericanos utilizando los criterios y definiciones acordados a escala internacional, así como herramientas y soluciones prácticas ajustadas a la realidad de la Región. Las actividades desarrolladas hasta ahora evidencian la necesidad y factibilidad de estandarizar la interpretación de las radiografías de tórax para utilizarlas en estudios epidemiológicos.

    Full Text Available Diferentes investigadores han realizado estudios sobre el manejo del niño febril y plantean que es un dilema al que se enfrenta a diario el médico que atiende niños. Motivados por este tema se efectuó un estudio descriptivo retrospectivo de los niños febriles, sin causa aparente en su valoración inicial, que asistieron al servicio de urgencias en un período de 9 meses, con el objetivo de identificar el diagnóstico definitivo al egreso y se precisó el tipo de infección bacteriana severa y relacionó la presencia de éstos con parámetros clínicos y de laboratorios. El mayor número de niños febriles valorados e ingresados mostraron edades desde 91 días hasta 36 meses. El menor porcenaje de ellos ingresaron y desarrollaron alguna infección bacteriana severa principalmente neumonía, y fue mayor el porcentaje de niños con esta patología a menos edad con predominio del aspecto tóxico y de la temperatura 39 EC. Resultó el manejo ambulatorio del niño febril mayor de 90 días y bajo riesgo de infección bacteriana severa un ahorro en vidas y dinero, por lo que se recomienda generalizar el flujograma propuesto para la evaluación y manejo del niño febril de 3 a 36 meses de edad.Different researches have performed studies on the management of the febrile infant and they point out that this is a dilemma faced by every physician who takes care of children. Motivated by this subject, a descriptive and retrospective study of febrile infants was conducted. The study was carried out to evaluate febrile infants without evident cause at the baseline evaluation who attended the emergency service during a period of 9 months with the objective of identifying the definite diagnosis at admission. The type of bacterial infection was accurately assessed and the presence of this was related to clinical and laboratory parameters.

    Full Text Available As broncopneumonias são afecções importantes na pecuária mundial, representando uma das principais causas de mortalidade de bezerros nos primeiros meses de vida. As medidas preventivas e terapêuticas adotadas geralmente são baseadas em resultados de estudos internacionais, não se conhecendo as bactérias implicadas nos quadros pneumônicos em animais criados no Brasil. Aliado a isso, no primeiro mês de vida, os bezerros demonstram imaturidade do sistema imune, o que tem sido pouco estudado em quadros pneumônicos. Desta maneira, objetivou-se estudar as broncopneumonias em bezerros neonatos, identificando bactérias do trato respiratório posterior de bezerros sadios e com pneumonias naturalmente adquiridas, bem como analisar citologicamente a resposta pulmonar frente a estes patógenos. Para isso amostras de lavado do trato respiratório foram colhidas por traqueocentese durante o primeiro mês de vida dos animais. Verificou-se que não houve diferença na microbiota traqueobrônquica de bezerros sadios em relação aos doentes, discordando dos relatos da literatura internacional, sendo constituída principalmente por: Staphylococcus sp., Bacillus sp., Streptococcus sp., Pseudomonas aeruginosa e enterobactérias, permitindo inferir que as medidas profiláticas e terapêuticas adotadas internacionalmente possam não ser tão efetivas para as criações brasileiras. Observou-se também que bezerros neonatos têm uma proporção aproximada de 1:1 de macrófagos e neutrófilos na região traqueobrônquica quando saudáveis, atingindo uma relação aproximada de 1:3 durante os quadros de broncopneumonias, sendo estes perfis provavelmente característicos da idade, período conhecido pela imaturidade do sistema imune e agravado por fatores de manejo que favoreçam uma maior inalação de agentes bacterianos.

    Full Text Available PCR analysis is a sensitive and specific tool to detect and monitormicroorganisms in complex environmental samples. The amplification of 16S ribosomal DNA sequences followed by gel electrophoresis under denaturing gradient (DGGE has been a powerful technique to genetically evaluate microbial ecosystems. Changes in rumenmicrobial populations were investigated in vitro using a basal diet with different lipid sources. PCRs were performed with two different sets of primers in order to amplify 16S rRNA sequences, and the amplified fragments were submitted to DGGE analysis. The findings presented in this study show that distinct microbial communities were present in each treatment. The presence of soybean oil seems to maximize growth of bacterial population, whereas fish oil appears to reduce growth. We demonstrated the successful application of molecular ecological techniques to analyze the structure and composition of bacterial communities in rumen ecosystems.A análise por PCR fornece um meio sensível e específico para detectar e monitorar microrganismos em amostras ambientais complexas. Desde sua aplicação inicial, o DNA ribossomal 16S (rRNA em eletroforese com gel com gradiente desnaturante (DGGE, tem sido uma técnica atrativa para a ecologia molecular microbiana. Foram investigadas mudanças na população microbiana no rúmen, a partir de alterações da dieta com tratamentos in vitro de diferentes fontes de lipídeos. ODGGE foi testado com dois pares de primers para o rRNA 16S. O uso do fragmento de 200 pb gerou um perfil de bandas mais discriminatório, mostrando que diferentes comunidades microbianas estavam presentes entre os tratamentos in vitro analisados. A presença de óleo de sojapotencializou o crescimento da população bacteriana, enquanto que óleo de peixe parece ter reduzido esse crescimento. Foi possível demonstrar o sucesso da aplicação de técnicas moleculares para analisar a estrutura e a composição de comunidades

    Full Text Available Apesar de amplamente empregados em lavouras de tomate para processamento industrial no Brasil, fungicidas cúpricos e antibióticos registrados para uso agrícola nem sempre resultam em controle eficiente das bacterioses que afetam a cultura. O aparecimento de estirpes resistentes é uma das causas dessa baixa eficiência. Avaliou-se, in vitro, a sensibilidade a cobre, estreptomicina e oxitetraciclina de 389 isolados de Xanthomonas spp. associadas à mancha-bacteriana do tomateiro, sendo 92 de X. axonopodis pv. vesicatoria (60 do grupo "A"/raça T1 e 32 do "C"/raça T3, 93 de X. vesicatoria (grupo "B"/raça T2 e 204 de X. gardneri (grupo "D"/raça T2. Os isolados foram obtidos de plantas doentes em campos comerciais de tomate para processamento industrial nos estados de Goiás, Minas Gerais, Pernambuco e Bahia, nos anos de 1995 a 1998 e em 2000. Alíquotas de 5 ml de suspensões bacterianas foram depositadas em meio Nutriente-Ágar suplementado com sulfato de cobre, nas concentrações de 50 e 200 µg/ml; sulfato de estreptomicina, a 25 e 200 µg/ml e cloridrato de oxitetraciclina, a 25 µg/ml. Nenhum isolado foi resistente a oxitetraciclina, como também nenhum foi resistente ao cobre na concentração de 200 µg/ml do sulfato de cobre. No entanto, houve diferença entre isolados quanto à sensibilidade ao sulfato de cobre na concentração de 50 µg/ml e ao sulfato de estreptomicina nas duas concentrações empregadas. As freqüências de isolados de X. gardneri, X. axonopodis pv. vesicatoria (grupos "A" e "C" e X. vesicatoria resistentes à estreptomicina (25 µg/ml do produto usado foram, respectivamente, 98%, 38% e 2%, ao passo que, ao cobre, foram, respectivamente, 48%, 4% e 74%.

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    Neonatal lupus erythematosus (NLE) is an uncommon disease of the neonate. It is believed to be caused by the transplacental passage of maternal autoantibodies to the ribonucleoproteins (Ro\\/SSA, La\\/SSB or rarely U RNP) as these are almost invariably present in NLE sera. The most common clinical manifestations include cutaneous lupus lesions and congenital complete heart block. Hepatobiliary and haematologic abnormalities are reported less frequently. We describe a patient with cutaneous NLE to illustrate and raise awareness of the characteristic annular eruption of this condition. We also emphasize the need for thorough investigation for concomitant organ involvement and for maternal education regarding risk in future pregnancies.

    Full Text Available El objetivo de esta investigación fue determinar la flora bacteriana del vampiro común (Desmodus rotundus primordialmente debido a que los datos al respecto están desactualizados, y además por la gran importancia económica de esta especie de murciélago. Veintiún murciélagos fueron recolectados y su flora bacteriana identificada separadamente a nivel de estómago e intestino. Las bacterias fueron identificadas con el Analytical Profile Index (API, y los resultados analizados con el paquete APILAB. Un total de treinta especies fueron aisladas en 16 hembras y cinco machos. Las especies más comunes fueron Escherichia coli y Staphylococcus aureus, aunque otras especies, como Acinetobacter johnsonii, Enterobacter sakazakii, Staphylococcus chromogenes, S. hyicus y S. xylosus también se aislaron con frecuencia. El número de especies identificadas en el estómago y el intestino fue significativamente diferente, siendo el intestino más diverso. Esto ha sido encontrado anteriormente en otros mamíferos, y se atribuye probablemente a la reducción en acidez. Asimismo, la mayoría de las especies identificadas en este estudio forman parte de la flora bacteriana normal del tracto digestivo de mamíferos, aunque también se encontraron otras bacterias comunes en la piel de mamíferos y en ambientes acuáticos Las bacterias de la piel podrían estar colonizando el estómago y/o intestino del vampiro cuando éste tiene contacto con sus presas, lo que sugiere que el hábito alimentario de esta especie facilita su colonización por microorganismos que no se encontrarían comúnmente en su tracto digestivo. Ya que también se identificaron bacterias comunes en ambientes acuáticos, es probable que D. rotundus consuma agua cuando esté disponible, lo que respalda los resultados de otros investigadores, y sugiere que esta podría ser una fuente adicional de invasión microbiana.Aerobic bacterial flora from the digestive tract of the common vampire bat

    2011-07-01

    Full Text Available El cáncer gástrico persiste como un problema importante de salud pública a nivel mundial. En Chile es la primera causa de mortalidad por tumores malignos. En 1962 se definió el concepto de cáncer gástrico precoz, pasando a ser una enfermedad curable si era pesquisado en estas etapas, con sobrevida de 90% o más a 5 años. La estrategia implementada en Japón para detectarlo en etapas precoces fue a través de estudios masivos en población presuntamente asintomática. Esta estrategia ha sido exitosa en los cánceres detectados en etapa precoz pero con alto costo y bajo rendimiento, no aplicable en países en desarrollo con alto riesgo. La endoscopía ha desplazado a la radiología en el estudio de las enfermedades del tubo digestivo. Otra forma de enfrentar el problema en países en desarrollo con alto riesgo, es focalizar la endoscopía en sujetos sintomáticos. Desde 1996 se desarrolla un programa de detección de cáncer gástrico mediante esta última estrategia en la comuna de La Florida, Región Metropolitana. Se presenta un análisis preliminar de 12 años de este programa y se comentan las dificultades para un diagnóstico precoz.

    Sutter, Mary Beth; Leeman, Lawrence; Hsi, Andrew

    2014-06-01

    Neonatal opioid withdrawal syndrome is common due to the current opioid addiction epidemic. Infants born to women covertly abusing prescription opioids may not be identified as at risk until withdrawal signs present. Buprenorphine is a newer treatment for maternal opioid addiction and appears to result in a milder withdrawal syndrome than methadone. Initial treatment is with nonpharmacological measures including decreasing stimuli, however pharmacological treatment is commonly required. Opioid monotherapy is preferred, with phenobarbital or clonidine uncommonly needed as adjunctive therapy. Rooming-in and breastfeeding may decease the severity of withdrawal. Limited evidence is available regarding long-term effects of perinatal opioid exposure. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available El fósforo (P es un elemento esencial para la vida, por lo cual entender los mecanismos que permiten su disponibilidad en el suelo es prioritario. Debido a la complejidad de la dinámica de este nutriente, aún existen varios procesos que no están claramente entendidos, principalmente en los ecosistemas oligotróficos. En la presente revisión se analiza literatura relacionada con procesos involucrados en la disponibilidad del P, dándole énfasis al papel de las bacterias. La forma química disponible del P es el ortofosfato, pero por su alta reactividad y demanda de la biota, esta forma es rápidamente disminuida de la solución del suelo. Por lo que es necesario que la biota adquiera este elemento de otras formas químicas. Entre ellas, las formas orgánicas representan la principal fuente de este nutriente mediante la mineralización bioquímica producto principalmente de la comunidad bacteriana del suelo. Entre los compuestos organofosforados, los ésteres de fosfatos son los más fáciles de mineralizar, por la poca demanda energética en la producción de las enzimas involucradas en dicho proceso. Por otro lado, la mineralización de los fosfonatos puede representar una fuente alternativa de P disponible, a pesar de que se había considerado que esta forma química no era accesible por la complejidad de sus moléculas. En general, una estrategia exitosa para la adquisición de P en ecosistemas donde dicho elemento es limitado, depende de la presencia de una maquinaria genética capaz de sintetizar las diferentes enzimas que mineralizan compuestos orgánicos con demandas energéticas diferentes (fosfohidrolasas, fosfonatasas y C-P liasas, además de la presencia de transportadores específicos de membrana y la disponibilidad de C como fuente de energía. Aún faltan estudios integrados que permitan elucidar el movimiento del P en los ecosistemas y cómo esto puede ser controlado y llevado a cabo por las bacterias que habitan en el suelo.

    Full Text Available New knowledge of the structure and biological activity of endotoxins (LPS has revolutionized concepts concerning their mechanisms of action and forms of inactivation. Since the 1980's, technological advances in microbiological culture and identification have shown that anaerobic microorganisms, especially Gram-negative, predominate in root canals of teeth with pulp necrosis and radiographically visible chronic periapical lesions. Gram-negative bacteria not only have different factors of virulence and generate sub-products that are toxic to apical and periapical tissues, as also contain endotoxin (LPS on their cell wall. This is especially important because endotoxin is released during multiplication or bacterial death, causing a series of biological effects that lead to an inflammatory reaction and resorption of mineralized tissues. Thus, due to the role of endotoxin in the pathogenesis of periapical lesions, we reviewed the literature concerning the biological activity of endotoxin and the relevance of its inactivation during treatment of teeth with pulp necrosis and chronic periapical lesion.O conhecimento mais aprofundado sobre a estrutura e atividade biológica das endotoxinas (LPS revolucionou os conceitos sobre seu mecanismo de ação e formas de inativação. A partir da década de 80, os avanços tecnológicos na cultura e identificação microbiológica demonstraram que, em canais radiculares de dentes portadores de necrose pulpar e lesão periapical crônica, visível radiograficamente, predominam microrganismos anaeróbios, particularmente os gram-negativos. Como se sabe, os microrganismos gram-negativos, além de possuírem diferentes fatores de virulência e gerarem produtos e sub-produtos tóxicos aos tecidos apicais e periapicais, contêm endotoxina em sua parede celular. Esse conhecimento é particularmente importante, uma vez que a endotoxina é liberada durante a multiplicação ou morte bacteriana, exercendo uma série de

    Full Text Available A descriptive cross sectional study was carry out in 423 women in seven rural communities of the municipality of Amagá, Antioquia. One of the objectives of this study was to evaluate the sensibility and specificity and predictive values of the test of Papanicolaou in relation to the Gram exam, for the diagnosis of Bacterial Vaginosis (BV. In the 423 studied women the results showed a prevalence of BV for the bacteriological exam Gram of 20.8 % (88 cases and for Papanicolaou of 21% (89 cases. The sensitivity was 87.5%, the specificity was 96.4%. The value predictive positive was 86,5% and the value predictive negative was 96.7%. The high sensitivity, specificity and predictive values of the Papanicolaou test reported in this study make it a good screening method, since it is an exam that is carried out commonly and no additional testa are required. Se realizó un estudio descriptivo de corte en 423 mujeres de la población rural del municipio de Amagá, Antioquia, cuyas edades estaban comprendidas entre los 15 y 65 años, a quienes se les tomó muestras cérvicovaginales para estudio citológico de Papanicolau y coloración de Gram. El objetivo de este estudio fue evaluar la sensibilidad, especificidad y valores predictivos de la prueba de Papanicolaou frente al Gram, para el diagnóstico de vaginosis bacteriana (vb. La prevalencia de vb por el Gram, en las 423 mujeres estudiadas, fue de 20.8% (88 casos y la prevalencia de vb por Papanicolaou, fue del 21 % (89 casos. La sensibilidad fue 87.5%, la especificidad 96.4%, valor predictivo positivo (VPP 86,5% y valor predictivo negativo (VPN 96.7%. La alta sensibilidad, especificidad y valores predictivos de la prueba de Papanicolaou, reportados en este estudio hacen de ésta un buen método de tamizaje, dado que es un examen que se realiza de rutina y no se requiere una prueba adicional para hacer el diagnóstico; lo que a su vez permite disminuir costos porque se omite el estudio de la flora vaginal

    Healy, Patricia; Fallon, Anne

    This article reviews the origins and evolution of neonatology and considers the role of the neonatal nurse within this specialty. Neonatal nurses are a vital part of the neonatal team that provides care for sick babies. The nursing care required by sick babies and their families on a neonatal unit can be variable and complex. The past century has seen significant changes in the role of the neonatal nurse. This has come about through dramatic technological developments on neonatal units, an increased understanding of neonatal physiology and pathology, changes in the education of neonatal nurses, and active and ongoing clinical research within the specialty. The resulting significant advances in neonatal care, including that provided by neonatal nurses, have made a crucial and steadfast contribution to marked improvements in neonatal outcomes.

    Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice.

    2014-02-01

    Neonatal hypoglycemia is one of the most common biochemical abnormalities encountered in the newborn. However, controversy remains surrounding its definition and management especially in asymptomatic patients. New information has been published that describes the incidence and timing of low glucose concentrations in the groups most at risk for asymptomatic neonatal hypoglycemia. Furthermore, one large prospective study failed to find an association between repetitive low glucose concentrations and poor neurodevelopmental outcomes in preterm infants. But hypoglycemia due to hyperinsulinism, especially genetic causes, continued to be associated with brain injury. New advances were made in the diagnosis and management of hyperinsulinism, including acquired hyperinsulinism in small for gestational age infants and others. Continuous glucose monitoring remains an attractive strategy for future research in this area. The fundamental question of how best to manage asymptomatic newborns with low glucose concentrations remains unanswered. Balancing the risks of overtreating newborns with low glucose concentrations who are undergoing a normal transition following birth against the risks of undertreating those in whom low glucose concentrations are pathological, dangerous, and/or a harbinger of serious metabolic disease remains a challenge.

  8. Neonatal status of twins

    Full Text Available Multiple pregnancy is a pregnancy where more than one fetus develops simultaneously in the womb, as a result of the ovulation and fertilization of more than one egg. It is relatively rare in humans and represents the rest of the phylogenetic stages. The most common are twins and they indicate the development of two fetuses in the womb. The frequency of twin pregnancies is about 1%. Multiple pregnancies belong to a group of high-risk pregnancies because of the many complications that occur during the pregnancy: higher number of premature deliveries, bleeding, early neonatal complications and higher perinatal morbidity and mortality. Such pregnancies and infants require greater supervision and monitoring. The aim of this study was to determine the percentage of baby twins born at the maternity ward of the General Hospital in Prokuplje and their morbidity and mortality. Data on the total number of deliveries, number of twins, parity and maternal age, gestational age, body weight of twins, method of delivery, Apgar score and perinatal mortality were collected and statistically analyzed by means of retrospective analysis of operative birth and neonatal protocol for 6 years (2005 of 2010. Out of 4527 mothers who gave birth 43 were pairs of twins, or 0.95% of women gave birth to twins. These babies are more likely born by Caesarean section, but delivered with slightly lower birth weight.

    Neonatal sigmoid volvulus is a rare entity. It is associated with Hirschsprung's disease. Presentation is acute abdominal distention, vomiting and obstipation. Abdominal radiograph will show the "coffee bean" sign, but this is frequently missed and the diagnosis requires a high index of suspicion. Treatment options include contrast enema, colonoscopy or laparotomy, depending on the condition of the baby and local availability. During the last 6years, 6 infants with sigmoid volvulus were treated in our department. Four presented during the first 48h since birth, and 2 presented at the age of 2 and 7weeks of age. One child was operated and 5 had primary contrast enema with radiologic de-volvulus. Rectal biopsy was performed in all cases; three children had Hirschsprung's disease. Those with normal biopsies responded well to rectal washouts. Two patients had early one stage transanal pullthrough and one had 2 further occasions of sigmoid volvulus prior to definitive surgery. All three recovered with an uneventful course. Neonatal sigmoid volvulus requires a high level of suspicion. Contrast enema is efficient for primary de-volvulus. Rectal biopsy should be performed and if positive for Hirschsprung's disease, surgery should be performed sooner rather than later. Copyright © 2016 Elsevier Inc. All rights reserved.

  13. Neonates need tailored drug formulations.

    2013-02-08

    Drugs are very strong tools used to improve outcome in neonates. Despite this fact and in contrast to tailored perfusion equipment, incubators or ventilators for neonates, we still commonly use drug formulations initially developed for adults. We would like to make the point that drug formulations given to neonates need to be tailored for this age group. Besides the obvious need to search for active compounds that take the pathophysiology of the newborn into account, this includes the dosage and formulation. The dosage or concentration should facilitate the administration of low amounts and be flexible since clearance is lower in neonates with additional extensive between-individual variability. Formulations need to be tailored for dosage variability in the low ranges and also to the clinical characteristics of neonates. A specific focus of interest during neonatal drug development therefore is a need to quantify and limit excipient exposure based on the available knowledge of their safety or toxicity. Until such tailored vials and formulations become available, compounding practices for drug formulations in neonates should be evaluated to guarantee the correct dosing, product stability and safety.

    Full text: Hypoxic-Ischemic insults in the brain of neonates constitute major cause of morbidity and mortality. A wide range of motor, sensory, and cognitive disabilities are observed in this population spanning from slight motor deficits, school difficulties and behavioral problems up to cerebral palsy and mental retardation. Pathologically involved areas characterized by high metabolic demands and therefore with enhanced vulnerability to any reduction or cessation of energy and oxygen supply. Watershed areas of the brain (vascular end zones and vascular border zones) are predominately affected in any adverse event. Radiologic and pathologic appearance of these lesions depends both on the severity of the insult and the maturity of the brain. The dominant pathology observed in preterm neonates is white matter lesions. There are three basic patterns of brain destruction in this population. Periventricular leukomalacia (PVL focal fPVL, diffuse dPVL), germinal matrix haemorrhage (GMH) associated with intraventricular haemorrhage (IVH), and parenchymal haemorrhage (PH). fPVL is characterized by focal necrosis of all cellular elements in the periventricular white matter, resulting in the formation of cysts, and dPVL is characterized by diffuse destruction of the premyelinating oligodendrocytes (pre-OLs) the precursors of mature oligodendroglia cells responsible for the formation of myelin in a later stage. GMH is located beneath germinal matrix layer surrounding the lateral ventricles and can extend into the ventricular system resulting thus to IVH. Finally, PH is located within the parenchyma adjacent to the ventricles and is believed to represent haemorrhagic infarcts following venous drainage compromise. In term or near-term neonates, the top-ographic pattern of injuries involves mainly gray matter structures. Most frequent predilection sites include the cerebral cortex (paracentral lobule, Rolandic area, visual cortex and hippocampus), basal ganglia, thalamus, and

    Full Text Available Rapel reservoir is an eutrophic system in Chile that has undergone a series of anthropogenic impacts in recent decades. To provide a better understanding of the processes occurring in the reservoir, we examined bacterial composition from surface sediments using traditional microbiology techniques and molecular biology tools. Our results showed significant temporal variation in the physical and chemical composition of the water column, but no depth-related differences during the study period. To detect temporal changes in bacterial composition, cultivable heterotrophic bacteria, heterotrophic iron oxidizing bacteria, and sulfate-reducing bacteria were extracted from the surface sediments and their concentration measured. Microbial diversity in sediments was represented by closest relatives of eight different bacterial phyla. The most frequently recovered phylotypes in the clone library of 16S rDNA were related to sulfate-reducing bacteria belong to the Deltaproteobacteria groupEl embalse Rapel es un sistema eutrófico en Chile que ha experimentado diversos impactos antropogénicos en las últimas décadas. Para conocer mejor los posibles procesos que ocurren en el embalse, la composición bacteriana fue estudiada en la zona superficial de los sedimentos utilizando técnicas microbiológicas tradicionales y herramientas de biología molecular. Nuestros resultados mostraron variación temporal significativa en la composición física y química del agua, no encontrándose diferencias de las variables medidas entre superficie y fondo en la columna de agua durante el período de estudio. Para detectar cambios temporales en la concentración y composición bacteriana, se midieron bacterias heterótrofas, heterótrofas oxidantes de fierro y bacterias reductoras de sulfato extraídas de la superficie de los sedimentos.

Su cuantificación es importante en la determinación del impacto de las prácticas agrícolas y el cambio de uso de la tierra sobre la calidad del suelo. El objetivo de este estudio fue determinar, a través del método de inhibición selectiva, la biomasa fúngica y bacteriana y la relación (H:B en suelos de sabana nativa sustituidos por pinares (Pinus caribaea var. hondurensis, para establecer si éstos parámetros son indicadores sensibles de cambios en el contenido de carbono en suelos de Uverito, Venezuela. La relación de aditividad del inhibidor (RAI y la inhibición total por efecto combinado del inhibidor (ITC se llevaron a cabo para determinar, si los inhibidores microbianos tuvieron actividad sobre otros organismos para los cuales éstos no estaban destinados. La cuantificación de la biomasa fúngica y bacteriana se llevó a cabo mediante el uso de la cycloheximida como inhibidor fúngico, y la estreptomicina y el cloranfenicol como inhibidores bacterianos. Esta investigación evidencia que este cambio de uso de la tierra ejerció un efecto significativo sobre la biomasa microbiana del suelo, y muestra que en el sistema de pinares existe una dominancia del componente fúngico, en contraste con la sabana nativa, en la cual domina la biomasa bacteriana. La sustitución de la sabana nativa por plantaciones de pino en Uverito, promueve un mayor secuestro del carbono en el suelo. Los valores de la relación de aditividad del inhibidor (RAI tanto para la sabana nativa como para el sistema de pinares, resultaron ambos >1.0.

    The association between pediatric cancer and congenital abnormalities is well known but, there is no exclusive data on the neonatal period and the underlying etiopathogenic mechanisms are unknown. First, to analyze the frequency of neonatal tumours associated with congenital abnormalities; and second, to comment on the likely etiopathogenic hypotheses of a relationship between neonatal tumours and congenital abnormalities. Historical series of neonatal tumours from La Fe University Children's Hospital in Valencia (Spain), from January 1990 to December 1999. Histological varieties of neonatal tumours and associated congenital abnormalities were described. A systematic review of the last 25 years was carried out using Medline, Cancerlit, Index Citation Science and Embase. The search profile used was the combination of "neonatal/congenital-tumors/cancer/neoplasms" and "congenital malformations/birth defects". 72 neonatal tumours were identified (2.8% of all pediatric cancers diagnosed in our hospital) and in 15 cases (20.8%) there was some associated malformation, disease or syndrome. The association between congenital abnormalities and neonatal tumours were: a) angiomas in three patients: two patients with congenital heart disease with a choanal stenosis, laryngomalacia; b) neuroblastomas in two patients: horseshoe kidney with vertebral anomalies and other with congenital heart disease; c) teratomas in two patients: one with cleft palate with vertebral anomalies and other with metatarsal varus; d) one tumour of the central nervous system with Bochdaleck hernia; e) heart tumours in four patients with tuberous sclerosis; f) acute leukaemia in one patient with Down syndrome and congenital heart disease; g) kidney tumour in one case with triventricular hydrocephaly, and h) adrenocortical tumour: hemihypertrophy. The publications included the tumours diagnosed in different pediatric periods and without unified criteria to classify the congenital abnormalities. Little data

    Abdominal surgery in foals under 30 days old has become more common with improved neonatal care. Early recognition of a foal at risk and better nursing care have increased the survival rates of foals that require neonatal care. The success of improved neonatal care also has increased the need for accurate diagnosis and treatment of gastrointestinal, umbilical, and bladder disorders in these foals. This chapter focuses on the early and accurate diagnosis of specific disorders that require abdominal exploratory surgery and the specific treatment considerations and prognosis for these disorders.

    Perinatal infection may potentiate brain injury among children born preterm. The objective of this study was to examine whether maternal and/or neonatal infection are associated with adverse outcomes among term neonates with encephalopathy. This study is a cohort study of 258 term newborns with encephalopathy whose clinical records were examined for signs of maternal infection (chorioamnionitis) and infant infection (sepsis). Multivariate regression was used to assess associations between infection, pattern, and severity of injury on neonatal magnetic resonance imaging, as well as neurodevelopment at 30 mo (neuromotor examination, or Bayley Scales of Infant Development, second edition mental development index encephalopathy, chorioamnionitis was associated with a lower risk of brain injury and adverse outcomes, whereas signs of neonatal sepsis carried an elevated risk. The etiology of encephalopathy and timing of infection and its associated inflammatory response may influence whether infection potentiates or mitigates injury in term newborns.

    Respiratory distress is a very common and yet non-specific symptom in neonates and young infants. It may be manifested clinically in many ways, including tachypnea, apnea, periodic respiratory, grunting, retractions, nasal flaring, and cyanosis. In many instances, the chest radiograph is diagnostic or at least suggestive of the diagnosis. This fact is important in determining surgical or medical conditions that require emergency therapy. Even if the chest film is normal, valuable information can be gained. This initial normal radiograph can be used as a baseline film in the face of further developing symptoms which, likewise, may have developing radiographic findings. In any event, the chest radiograph gives the clinician ''direction'' in his or her search for the cause of the patient's respiratory distress

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is a rare complex entity characterized clinically by acute or recurrent episodes of hemoptysis secondary to diffuse alveolar hemorrhage. The radiographic features are variable, including diffuse alveolar-type infiltrates, and interstitial reticular and micronodular patterns. We describe a 3-week-old infant presenting with hemoptysis and moderate respiratory distress. Idiopathic pulmonary hemosiderosis was the first working diagnosis at the Emergency Department and was confirmed, 2 weeks later, by histological studies (bronchoalveolar lavage. The immunosuppressive therapy by 1 mg/kg/d prednisone was immediately started, the baby returned home on steroid therapy at a dose of 0,5 mg/kg/d. The diagnosis of idiopathic pulmonary hemosiderosis should be evocated at any age, even in the neonate, when the clinical presentation (hemoptysis and abnormal radiological chest images is strongly suggestive.

    Although largely deprived from exogenous stimuli in utero, the mucosal barriers of the neonate after birth are bombarded by environmental, nutritional, and microbial exposures. The microbiome is established concurrently with the developing immune system. The nature and timing of discrete interactions between these two factors underpins the long-term immune characteristics of these organs, and can set an individual on a trajectory towards or away from disease. Microbial exposures in the gastrointestinal and respiratory tracts are some of the key determinants of the overall immune tone at these mucosal barriers and represent a leading target for future intervention strategies. In this review, we discuss immune maturation in the gut and lung and how microbes have a central role in this process.

    Kinship, understood as biogenetic proximity, between a chosen animal model and a human patient counterpart, is considered essential to the process of ‘translating’ research from the experimental animal laboratory to the human clinic. In the Danish research centre, NEOMUNE, premature piglets are fed...... a novel milk diet (bovine colostrum) to model the effects of this new diet in premature infants. Our ethnographic fieldwork in an experimental pig laboratory and a neonatal intensive care unit (NICU) in 2013–2014 shows that regardless of biogenetics, daily practices of feeding, housing, and clinical care...... the researchers refer to as the ‘translatability’ of the results. In the NICU, parents of premature infants likewise imagine a kind of interspecies kinship when presented with the option to supplement mother's own milk with bovine colostrum for the first weeks after birth. However, in this setting the NICU...

    Technological advances have caused a decrease in the number of infant deaths. Pre-term infants now have a substantially increased chance of survival. One of the mechanisms that is vital to saving the lives of these infants is continuous monitoring and early diagnosis. With continuous monitoring huge amounts of data are collected with so much information embedded in them. By using statistical analysis this information can be extracted and used to aid diagnosis and to understand development. In this study we have a large dataset containing over 180 pre-term infants whose heart rates were recorded over the length of their stay in the Neonatal Intensive Care Unit (NICU). We test two types of models, empirical bayesian and autoregressive moving average. We then attempt to predict future values. The autoregressive moving average model showed better results but required more computation.

    A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

    The future of neonatal informatics will be driven by the availability of increasingly vast amounts of clinical and genetic data. The field of translational bioinformatics is concerned with linking and learning from these data and applying new findings to clinical care to transform the data into proactive, predictive, preventive, and participatory health. As a result of advances in translational informatics, the care of neonates will become more data driven, evidence based, and personalized. PMID:22924023

    Full Text Available Nos ambientes tropicais, os Cerrados destacam-se pelo seu potencial agrícola. Apesar das funções dos microrganismos no crescimento das plantas e na produtividade das culturas, existem poucas informações dos efeitos resultantes do manejo do solo, na ecologia microbiana. Neste estudo, foram avaliados os efeitos das condições ambientais e das práticas agrícolas sobre as populações bacterianas. As densidades das populações em solos com vegetação nativa foram variáveis e diferenciadas. Em Sete Lagoas, MG, as populações de actinomicetos variaram de 1,7 a 50 X 10(4 UFC/g de solo seco, enquanto em Planaltina as densidades das populações bacterianas em solo com primeiro e segundo ano de cultivo de soja foram semelhantes, mas superiores ao solo com vegetação nativa. A utilização agrícola deste solo não resultou em desequilíbrios acentuados das populações de actinomicetos provenientes de esporos e hifas. As relações esporos/hifas variaram de 1,1 a 5,8. Na rizosfera da soja, os coeficientes de correlação entre as populações de actinomicetos com as demais populações bacterianas foram significativos. Os resultados evidenciam que as práticas agrícolas utilizadas na introdução da cultura da soja em solos de Cerrados pode influenciar o equilíbrio das populações na comunidade bacteriana.Among tropical environments, Cerrados stand out because of its agriculture potencial. Although microorganisms play an important role on soil sustainability and crop production, few information is available on the effects of soil management systems on Cerrado's microbial ecology.

    Full Text Available La diferenciación rápida de colonias bacterianas es esencial en muchos campos industriales, científicos y de salud humana y animal. Generalmente esa diferenciación se logra por técnicas microscópicas, bioquímicas o genéticas muy elaboradas que requieren tiempo y entrenamiento. En este estudio se utilizaron técnicas de análisis de imágenes sobre patrones de difracción de luz láser para evaluar su sensibilidad en la diferenciación de colonias bacterianas. Adicionalmente se estudió el efecto del tiempo de crecimiento de las colonias en la generación de estos patrones y se determinó la influencia de la cantidad de medio de cultivo en la difracción de luz láser. Los patrones de difracción del láser se obtuvieron sobre cultivos puros de cinco aislamientos bacterianos B1, B2, B3, B2Ca y B2Cb. En la primera prueba de diferenciación se utilizaron colonias de B2, B3, B2Ca. En el estudio del efecto del tiempo de crecimiento sobre patrones de difracción, las bacterias B1 y B2Cb con uno o dos días de crecimiento. Finalmente, el efecto de la cantidad de medio de cultivo en la difracción de la luz, se evaluó en una prueba en cajas petri con 10, 15 o 20 ml de medio de cultivo estéril sin colonias de bacterias. Mediante un análisis de escalado multidimensional realizado con los parámetros de textura extraídos de las imágenes de los patrones, se obtuvo un agrupamiento adecuado de los patrones asociados a las colonias de cada bacteria evaluada, lo cual indicó que las colonias bacterianas se pueden diferenciar por sus patrones de difracción. Adicionalmente se encontró que no hay variaciones significativas en los patrones de difracción obtenidos de dos aislamientos bacterianos en dos tiempos de crecimiento. El espesor del medio de cultivo afectó la difracción del haz de luz pues patrones obtenidos de cajas petri con 10 ml se separan completamente de los patrones obtenidos con 15 y 20 ml, aunque no hay diferencias entre los dos

    Full Text Available Introducción La reducción y osteosíntesis de las fracturas del tobillo, permiten una recuperación precoz. Sin embargo, clásicamente no se permite la carga del peso durante casi 6 semanas. El objetivo del presente estudio, es analizar si la carga inmediata del peso en fracturas de peroné, produce complicaciones y/o desplazamientos secundarios. Material y métodos Se analizaron 21 pacientes operados de fracturas 44AOB1, y se les dio carga inmediata. Se evaluó clínica y radiográficamente la evolución de los mismos. El seguimiento fue a más de 3 meses. Resultados La carga del peso con protección con bota “Walker”, fue ejecutada por los pacientes a los 2 días promedio. El puntaje AOFAS para tobillo evaluado a los 3 meses del post-operatorio fue de 99 puntos promedio. El retorno a la actividad laboral fue promedio 2,1 meses; y el retorno a la actividad deportiva previa, fue promedio de 2,95 meses. En la radiología del POP a más de 90 días de seguimiento, la reducción no sufrió desplazamientos secundarios. Discusión Aun existe controversia sobre el manejo postoperatorio en las fracturas de tobillo. Actualmente se sabe que el movimiento temprano luego de la fijación interna, es beneficioso para disminuir la enfermedad del yeso. La carga de peso temprana facilitaron la restauración de la amplitud de movimiento de la articulación lesionada, disminuyeron la hinchazón, la atrofia de los tejidos blandos, y previnieron el desarrollo de osteoporosis. Conclusiones Las fracturas tipo AO 44B1 de baja energía, tratados mediante reducción y osteosíntesis, pueden realizar carga de peso precoz, sin riesgo de desplazamientos secundarios. La carga precoz junto a la movilización temprana, presenta muy buena evolución clínica, y no incide en un mayor índice de complicaciones.

    Full Text Available Bacterial cellulose is a polymer obtained by fermentation with microorganismsfrom Acetobacter, Rhizobium, Agrobacterium and Sarcina genera. Amongthem, Acetobacter xylinum is the most efficient specie. This polymer hasthe same chemical composition of plant cellulose, but its conformation andphysicochemical properties are different, making it attractive for several applications, especially in the areas of food, separation processes, catalysis andhealth, due to its biocompatibility. However, the main problem is the production in mass that is constrained by low yield. It is therefore necessaryto develop some alternatives. This paper presents a review about synthesis,production, properties and principal applications of bacterial cellulose, as wellas some alternatives to reduce the difficulties for process scaling.La celulosa bacteriana es un polímero obtenido por fermentación con microrganismosde los géneros Acetobacter, Rhizobium, Agrobacterium y Sarcina, delas cuales la especie más eficiente es la Acetobacter Xylinum. Este polímero presenta la misma estructura química de la celulosa de origen vegetal, pero difiereen su conformación y propiedades fisicoquímicas, lo que lo hace atractivo para diversas aplicaciones, especialmente en las áreas de alimentos, procesosde separación, catálisis y en medicina, gracias a su biocompatibilidad. Sin embargo, el principal problema es la producción a gran escala limitada por losbajos rendimientos, lo que genera la necesidad de desarrollar alternativas que permitan disminuir o eliminar las causas de esta limitación. En este artículo se hace una revisión acerca de la síntesis, producción, propiedades y principales aplicaciones de la celulosa bacteriana, así como de algunas alternativas estudiadas para disminuir los inconvenientes en el escalamiento del proceso.

    Full Text Available As infecções bacterianas cursam com altos índices de morbilidade e mortalidade na cirrose hepática. O objetivo do nosso trabalho foi avaliar se também na hepatite alcoólica as infecções bacterianas são fatores de mau prognóstico. Na avaliação retrospectiva de 681 pacientes hospitalizados em um único centro, por período de 6 anos, foram bem documentados 52 (7,5% casos de hepatite alcoólica, sendo 73,1% com biópsia hepática para análise histopatológica e os restantes por diagnóstico clínico-bioquímico. Houve predomínio do sexo masculino (relação 3,3:1,0, com idade média de 40 anos e ingestão média de etanol puro de 193g/dia por mais de 3 anos. As principais complicações foram: encefalopatia hepática (n=5, insuficiência renal (n=4 e hemorragia digestiva alta (n=3. Houve infecção bacteriana em 11 (21,1% pacientes, sendo pulmonar (n=5, peritonite bacteriana espontânea (PBE (n=2, urinária (n=3 e dermatológica (n=1. Óbito precoce, durante o período de internação ocorreu em 8 (15,4% casos e a análise comparativa entre eles e os sobreviventes mostrou serem fatores de mau prognóstico a presença de encefalopatia hepática (p=0,012, bilirrubinas > 20mg% (p=0,012 e associação com infecções graves (pulmonar/PBE, com p=0,004. Em conclusão, demonstramos que as infecções bacterianas são fatores de mau prognóstico na hepatite alcoólica. Recomendamos, portanto, que a profilaxia com antibióticos que se faz durante hemorragia digestiva alta na cirrose e em casos de insuficiência hepática fulminante, seja estendida para a hepatite alcoólica, em sua forma grave, com finalidade de evitar infecções bacterianas e mortalidade precoce.Bacterial infections increase morbidity and mortality in cirrhosis.

    Full Text Available Neonatal tetanus (NNT has been secondary in the whole world in the death list of diseases which can be protected by the help of vaccine. It’s an important community health problem in the less-developed countries in which pre-birth care services are limited, assisting a mother at childbirth by uneducated people in dirty atmosphere and the immunity against tetanus is not enough. Studies have shown that minor part of the cases have been expressed in most of the countries. Because of that NNT have been called as “silent/invisible murderer”. In Turkey, in the year of 2003 it has been seen 15 cases, and 12 of them have been resulted in death. The methods which will be applied to carry out the elimination of NNT are; the vaccination of pregnant women with at least two doses tetanus toxoid and providing clean birth conditions for all of the pregnant women. However, in Turkey the proportion of the women who have two doses of tetanus vaccine is 41%. To eliminate NNT in our country, all the pregnant women must be attained, the ones who are attained must be presented with qualified pre-birth care service which also includes tetanus immunity and the births must be carried out under healty conditions. As smallpox and polio eradication, NNT elimination will also be accomplished by self-sacrificing works of personnel in primary health care. [TAF Prev Med Bull 2006; 5(3.000: 229-233

    In a retrospective multi-center study, we investigated eighteen infants with unilateral cerebral infarctions confirmed by computed tomography (CT) scans. The initial symptoms were observed in all the patients between 0 and 3 days of age. Convulsions or apneic attacks were the initial symptoms in all but one. Only 4 patients had complicated obstetric histories and none showed polycythemia or electrolyte abnormalities. All of the initial CT scans revealed unilaterally localized hypodense areas. In 10, the initial CT scans were performed within 24 hours after the clinical onset. In 16, the lesions were within the territory of the middle cerebral artery, 9 of which also involved the cortico-spinal tract (CST). In the remaining 2 patients, the lesions were located whithin the territory of the posterior cerebral artery. None of the 9 patients without CST involvement developed hemiplegia, whereas 5 (56%) of the 9 with CST involvement had hemiplegia, which is a fairly low incidence compared with that in adult cases. This difference was thought to be related to neonatal brain plasticity. (author)

  10. Neonatal aortic stenosis.

    Drury, Nigel E; Veldtman, Gruschen R; Benson, Lee N

    2005-09-01

    Neonatal aortic stenosis is a complex and heterogeneous condition, defined as left ventricular outflow tract obstruction at valvular level, presenting and often requiring treatment in the first month of life. Initial presentation may be catastrophic, necessitating hemodynamic, respiratory and metabolic resuscitation. Subsequent management is focused on maintaining systemic blood flow, either via a univentricular Norwood palliation or a biventricular route, in which the effective aortic valve area is increased by balloon dilation or surgical valvotomy. In infants with aortic annular hypoplasia but adequately sized left ventricle, the Ross-Konno procedure is also an attractive option. Outcomes after biventricular management have improved in recent years as a consequence of better patient selection, perioperative management and advances in catheter technology. Exciting new developments are likely to significantly modify the natural history of this disorder, including fetal intervention for the salvage of the hypoplastic left ventricle; 3D echocardiography providing better definition of valve morphology and aiding patient selection for a surgical or catheter-based intervention; and new transcutaneous approaches, such as duel beam echo, to perforate the valve.

    A fatally ending index case of sepsis osteoarthritis that was diagnosed retrospectively initiated this report. This patient had severe, asymmetrically distributed metaphyseal growthdisturbances, many long bones. In order to determine the features of early radiologic diagnosis we report the findings of 7 further patients with neonatal septic osteoarthritis with clinical and radiological follow-up. The most important observation for early radiologic diagnosis of osteoarthritis is the displacement of fat layers along the metaphysis. Other findings of the soft tissues have the same diagnostic value as bone destruction and subperiosteal new bone formation found one to three weeks later on roentgenfilms. Detecting early signs of osteoarthritis helps in localizing the focus for bacteriologic diagnosis, which is to be more successful than blood cultures. Diagnosing a joint empyema initiates surgical intervention for pressure relief in order to avoid necrosis of the epiphysis as seen in the femoral bone in septic arthritis of the hip joint. Early diagnosis and treatment to destruction of growing cartilage is necessary to avoid gross disturbances and length discrepancies of long bones. In cases of sepsis called 'babygram' and a repeat examination 10 to 14 days later is mandatory. (orig.) [de

    Full Text Available BACKGROUND : Neonates receiving phototherapy have side effects like hypocalcemia and electrolyte changes. Our study is hereby intended to study the serum sodium changes due to phototherapy. AIMS : To evaluate the serum sodium changes in neonates receiving phototherapy f or neonatal hyperbilirubinemia. SETTINGS AND DESIGN : A prospective hospital based comparative study conducted on neonates admitted in the Neonatal Intensive Care Unit receiving phototherapy. METHODS AND MATERIAL : A predesigned proforma has aided the enroll ment of 252 newborns into the study. Serum bilirubin and serum sodium were determined before and after termination of phototherapy. The first samples were considered as controls. A comparative study was made between before and after phototherapy groups to determine the incidence of serum sodium imbalances. STATISTICAL ANALYSIS USED : Proportions will be compared using chi - square test. All data of various groups will be tabulated and statistically analyzed using suitable statistical tests (Student's t test. RESULTS : Male to Female ratio was 1.45 : 1. Incidence of low birth weight babies was 23% and preterm was 20.2%. Mean birth weight and gestational age was 2.84±0.51 kg and 38.44±1.98 wks respectively. Mean duration of phototherapy was 37.65±11.06 hrs. The incidence of hyponatremia post phototherapy found to be 6% which was more in low birth weight (LBW babies (17.2% , p48 hrs (p<0.001. Even the decline in mean serum sodium values after phototherapy found to be statistically significant. CONCLUSION : Our study shows that neonates u nder phototherapy are at higher risk of hyponatremia. This risk is greater in premature and LBW babies and hence this group of babies should be closely monitored for changes in serum sodium and should be managed accordingly.

  14. Hypothyroidism in Filipino neonates

    1988-01-01

    Thyroid hormone determination (T4, T3, rT3, TSH) in cord blood of 3,897 newborns was carried out in Metro Manila (non-endemic) and central, Northern and Southern Luzon (endemic for goiter). The objective is to detect congenital hypothyroidism and establish its incidence in new born Filipinos. This was done by radioimmunoassay, using commercial kits from Abbott Laboratories. The results obtained as mean values for non-endemic regions are: T4: 10.96 +- 2.25 ug/dl; T3: 60-64 +- 13.82 ng/dl; rT3: 250.4 +- 64.9 ng/dl; and TSH 5.89 +- 2.58 uU/ml, n=200. Mean values in endemic regions (n = 205) are T4: 9.46 +- 2.18 ug/dl; T3: 67.8 +- 12.05 ng/dl; rT3: 184.3 +- 32.7 ng/dl and TSH: 6.65 +- 3.13 uU/ml. From the above data, nomograms were drawn where the values obtained from each case were plotted. From non-endemic regions 28 positive cases were recalled and in the endemic regions 16 positive cases were also recalled for re-examination but most of them turned out to be false positive. As of now, four positive cases were found in Metro Manila, i.e. 4/2, 441 births and five in endemic regions out of 1,456 births so the incidence of neonatal hypothyroidism is 9/3,897 births. This is 9 times higher than most reports abroad which is about 1/4000 births. (Auth.). 36 refs; 10 tabs; 10 figs

  15. Fetal and neonatal thyrotoxicosis

    Batra, Chandar Mohan

    2013-01-01

    Fetal thyrotoxicosis is a rare disease occurring in 1 out of 70 pregnancies with Grave's disease or in 1 out of 4000-50,000 deliveries. The mortality is 12-20%, usually from heart failure, but other complications are tracheal compression, infections and thrombocytopenia. It results from transfer of thyroid stimulating immunoglobulins from mother to fetus through the placenta. This transplacental transfer begins around 20th week of pregnancy and reaches its maximum by 30th week. These autoantibodies bind to the fetal thyroid stimulating hormone (TSH) receptors and increase the secretion of the thyroid hormones. The mother has an active autoimmune thyroid disease or has been treated for it in the past. She may be absolutely euthyroid due to past treatment by drugs, surgery or radioiodine ablation, but still have active TSH receptor stimulating autoantibodies, which can cause fetal thyrotoxicosis. The other features of this disease are fetal tachycardia, fetal goiter and history of spontaneous abortions and findings of goiter, ascites, craniosyntosis, fetal growth retardation, maceration and hydrops at fetal autopsy. If untreated, this disease can result in intrauterine death. The treatment for this disease consists of giving carbimazole to the mother, which is transferred through the placenta to the fetus. The dose of carbimazole is titrated with the fetal heart rate. If the mother becomes hypothyroid due to carbimazole, thyroxine is added taking advantage of the fact that very little of thyroxine is transferred across the placenta. Neonatal thyrotoxicosis patients are very sick and require emergency treatment. The goal of the treatment is to normalize thyroid functions as quickly as possible, to avoid iatrogenic hypothyroidism while providing management and supportive therapy for the infant's specific signs and symptoms.

    2013-01-01

    Full Text Available Introduction. Neonatal hydrocolpos is a rare condition. Hydrocolpos is cystic dilatation of the vagina with fluid accumulation due to a combination of stimulation of secretary glands of the reproductive tract and vaginal obstruction. The differential for a neonatal presentation of lower abdominal mass includes urogenital anomalies, Hirschsprung’s, disease or sacrococcygeal teratoma. Prenatal diagnosis and early newborn imaging studies leads to early detection and treatment of these cases. Case. We report here two cases of neonatal hydrocolpos with prenatal diagnosis of lower abdominal mass. Postnatally, ultrasound, MRI imaging, and cystoscopy confirmed large cystic mass as hydrocolpos with distal vaginal obstruction. Both patients had enlarged renal system secondary to mass effect. Conclusion. High index of suspicion for hydrocolpos in a newborn presenting with fetal diagnosis of infraumbilical abdominal mass will facilitate timely intervention and prevention of complications.

    Computed tomography (CT) is used less often than other techniques on neonatal units. However, in the acute setting, CT can be invaluable in diagnosing or excluding potentially life-threatening conditions and guiding initial management in neonates. Common indications for scanning include trauma, suspected non-accidental injury, infection, or an acute hypoxic or metabolic event. The aim of this review is to provide an overview of the normal neonatal head at CT and compare this to the common pathological abnormalities. Several key features of each condition will be highlighted. It is important to note that some pathological conditions can have overlapping features at CT and, therefore, the clinical history and additional investigations are also of key importance in determining the diagnosis

    2000-01-01

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.) [de

    2015-12-01

    Full Text Available Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding.

    Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. The presentation of acne in this patient population sometimes represents virilization and may portend later development of severe adolescent acne. Neonatal and infantile acne vulgaris must be distinguished from other cutaneous disorders seen in newborns and infants. Infantile acne tends to be more pleomorphic and inflammatory, thus requiring more vigorous therapy than neonatal acne.

    Neonatal herpes simplex virus (HSV) is an uncommon but devastating infection in the newborn, associated with significant morbidity and mortality. The use of PCR for identification of infected infants and acyclovir for treatment has significantly improved the prognosis for affected infants. The subsequent use of suppressive therapy with oral acyclovir following completion of parenteral treatment of acute disease has further enhanced the long-term prognosis for these infants. This review article will discuss the epidemiology, risk factors and routes of acquisition, clinical presentation, and evaluation of an infant suspected to have the infection, and treatment of proven neonatal HSV disease.

    Susceptibility weighted imaging (SWI) is a well-established magnetic resonance technique, which is highly sensitive for blood, iron, and calcium depositions in the brain and has been implemented in the routine clinical use in both children and neonates. SWI in neonates might provide valuable additional diagnostic and prognostic information for a wide spectrum of neonatal neurological disorders. To date, there are few articles available on the application of SWI in neonatal neurological disorders. The purpose of this article is to illustrate and describe the characteristic SWI findings in various typical neonatal neurological disorders.

    Improved neonatal survival rates and antenatal diagnostic imaging is generating a growing demand for postnatal MRI examinations. Neonatal brain MRI is now becoming standard clinical care in many settings, but with the exception of some research centres, the technique has not been optimised for imaging neonates and small children. Here, we review some of the challenges involved in neonatal MRI, including recent advances in overall MR practicality and nursing practice, to address some of the ways in which the MR experience could be made more neonate-friendly.

    Full Text Available The purpose of this study was to compare the effectiveness of plaque control performed with electric and manual toothbrushes. Fifteen children with primary dentition and 14 children with mixed dentition were divided in two groups and randomly assigned to utilize a manual or an electric toothbrush. In the first session, professional plaque removal was performed, and the children spent 24 hours without brushing their teeth. In the second session, plaque was disclosed and assessed on all facial and lingual surfaces. After that, all children brushed their teeth with the predetermined toothbrush. The next procedure was the disclosure and measurement of residual plaque. After a period of 7 days, the children switched the kind of toothbrush, and the same procedures were repeated. According to the statistical analysis of the results, there were no significant differences concerning plaque removal when the toothbrushes were utilized by children with mixed dentition. On the other hand, the electric toothbrush promoted significantly greater plaque removal on the lingual surfaces of teeth from children with primary dentition.A proposta deste estudo foi comparar a eficácia da remoção de placa bacteriana pelas escovações elétrica e manual.

    The indications for neonatal tracheostomy may have changed with current noninvasive respiratory therapies compared with previous decades. To study the current trends in neonatal tracheostomy and identify the primary indication for the procedure and risk factors for failed extubation. This retrospective medical record review included 47 neonates who underwent tracheostomy from January 1, 2009, to December 31, 2013, at the University of Maryland Children's Hospital. Group 1 included infants undergoing tracheostomy for the primary indication of upper airway obstruction; group 2, infants with primary pulmonary disease. Data on weight, gestational age, comorbid conditions, congenital abnormalities, complications, outcomes, and indications for tracheostomy were compared statistically between groups. Differences in gestational age, birth weight, and age at tracheostomy. Among the 47 infants included in the study (30 boys; 17 girls, mean [SD] age, 113 [73] days), 31 (66%) demonstrated anatomical causes of airway obstruction, and 16 (34%) had significant pulmonary disease. Among infants with anatomical causes, subglottic stenosis represented the largest group (11 of 31 [35%]). The mean age at the time of tracheostomy was significantly lower in the group with airway obstruction (98.9 vs 146.9 days; difference, 48 [95% CI, 4.8-91.2] days; P = .04). No procedure-related morbidity or mortality was encountered. Anatomical upper airway obstruction may be returning as the most common indication for a neonatal tracheostomy, thereby supporting the belief that current respiratory therapies have lowered the burden of chronic lung disease and the need for prolonged ventilatory care.

  4. Photodegradation of riboflavin in neonates

    1987-01-01

    The biologically most important flavins are riboflavin and its related nucleotides, all highly sensitive to light. It is because of its photoreactivity and its presence in almost all body fluids and tissues that riboflavin assumes importance in phototherapy of neonatal jaundice. The absorption maxima of both bilirubin and riboflavin in the body are nearly identical: 445-450 (447) nm. In consequence, blue visible light will cause photoisomerization of bilirubin accompanied by photodegradation of riboflavin. This results in diminished erythrocyte glutathione reductase, which indicates generalized tissue riboflavin deficiency and red cell lysis. Single- and double-strand breaks in intracellular DNA have occurred with phototherapy. This light exposure of neonates may result also in alterations of bilirubin-albumin binding in the presence of both riboflavin and theophylline (the latter frequently given to prevent neonatal apnea). Many newborns, especially if premature, have low stores of riboflavin at birth. The absorptive capacity of premature infants for enteral riboflavin is likewise reduced. Consequently, inherently low stores and low intake of riboflavin plus phototherapy for neonatal jaundice will cause a deficiency of riboflavin at a critical period for the newborn. Supplementation to those infants most likely to develop riboflavin deficiency is useful, but dosage, time, and mode of administration to infants undergoing phototherapy must be carefully adjusted to avoid unwanted side effects

    The International Fetal and Newborn Growth Consortium for the 21(st) Century (INTERGROWTH-21(st) ) is a large-scale, population-based, multicentre project involving health institutions from eight geographically diverse countries, which aims to assess fetal, newborn and preterm growth under optimal conditions. Given the multicentre nature of the project and the expected number of preterm births, it is vital that all centres follow the same standardised clinical care protocols to assess and manage preterm infants, so as to ensure maximum validity of the resulting standards as indicators of growth and nutrition with minimal confounding. Moreover, it is well known that evidence-based clinical practice guidelines can reduce the delivery of inappropriate care and support the introduction of new knowledge into clinical practice. The INTERGROWTH-21(st) Neonatal Group produced an operations manual, which reflects the consensus reached by members of the group regarding standardised definitions of neonatal morbidities and the minimum standards of care to be provided by all centres taking part in the project. The operational definitions and summary management protocols were developed by consensus through a Delphi process based on systematic reviews of relevant guidelines and management protocols by authoritative bodies. This paper describes the process of developing the Basic Neonatal Care Manual, as well as the morbidity definitions and standardised neonatal care protocols applied across all the INTERGROWTH-21(st) participating centres. Finally, thoughts about implementation strategies are presented. © 2013 Royal College of Obstetricians and Gynaecologists.

    Full Text Available El diagnóstico precoz del carcinoma hepatocelular (CHC es fundamental, especialmente si se consigue cuando los nódulos son menores de 2 cm, dado que en esta fase la mayoría aún no han presentado invasión vascular y la aplicación de tratamientos radicales se acompaña de una alta tasa de supervivencia a largo plazo. Los avances en las técnicas de imagen en los últimos años han permitido llegar a un diagnóstico concluyente de CHC en algunos de estos nódulos de pequeño tamaño sin necesidad de realizar procedimientos invasivos. Sin embargo, el número de CHC que pueden ser diagnosticados mediante pruebas de imagen es bajo y en más de la mitad de los casos sigue siendo necesaria la realización de una biopsia. Por otro lado, la confirmación histológica de CHC en este tipo de nódulos es compleja y en muchas ocasiones imposible, dado el posible error de muestreo y la dificultad para diferenciar CHC bien diferenciado de nódulos displásicos en una muestra habitualmente con escaso material. Además, los marcadores tumorales séricos disponibles en la actualidad presentan un bajo rendimiento y carecen de utilidad en el diagnóstico precoz de CHC. Los progresos en el conocimiento de los mecanismos moleculares responsables de la transformación maligna permitirán aplicar una serie de técnicas de biología molecular para facilitar el diagnóstico de CHC de forma precoz, con resultados iniciales prometedores.Early diagnosis of hepatocellular carcinoma (HCC in nodules smaller than 2 cm detected by screening ultrasounds becomes essential given that, at that stage, no vascular invasion is usually detected and treatment is associated with a high rate of long-term survival. Improvements in imaging techniques in the last few years have allowed a conclusive diagnosis of HCC in these small nodules without invasive procedures. However, a conclusive diagnosis of HCC by imaging is not always possible and, in more than half of cases, biopsy is needed

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.) [German] Ein Infarkt im Stromgebiet der Zerebralarterien stellt eine wichtige Differentialdiagnose bei neurologischen Auffaelligkeiten in der Neonatalperiode dar. Die Inzidenz wird anhand von klinischer Daten auf 1:4000 Lebendgeborene geschaetzt. Da der Verlauf oft subklinisch ist, liegt die wahre Inzidenz wahrscheinlich hoeher. Diagnose: Bei der Diagnosestellung kommen dem Schaedelultraschall und der Doppelsonographie als leicht verfuegbaren Screening-Methoden eine zentrale Rolle zu.

    Full Text Available Em razão da urgência de se decidir por um tratamento clínico ou por uma intervenção cirúrgica imediata, o estudo da colestase neonatal prolongada envolve dois objetivos básicos: o diagnóstico diferencial entre atresia biliar e hepatite neonatal e a pesquisa dos agentes etiológicos associados. Desta maneira, através de estudo prospectivo desenvolvido na década de 1970, foram avaliadas 77 crianças portadoras de colestase neonatal prolongada para estabelecer o diagnóstico diferencial entre atresia biliar e hepatite neonatal e, numa segunda fase, 108 crianças, visando esclarecer a etiopatogenia da colestase neonatal prolongada. Os resultados do diagnóstico diferencial revelaram que, dos 18 atributos avaliados, apenas oito mostraram-se bons indicadores de atresia biliar, em ordem decrescente: ductos proliferados (espaço-porta, fibrose (espaço-porta, colestase (espaço-porta, cor das fezes -- acolia, hepatomegalia, colestase canalicular (lóbulo, infiltrado (espaço-porta, células gigantes (lóbulo. Estes oito atributos foram então compostos, mediante uma ponderação, em um único indicador de grande poder discriminativo, capaz de decidir o diagnóstico diferencial em 99% dos casos. Quanto à etiopatogenia, registrou-se: vírus rubéola 0%, vírus herpes simples 0%, listeriose 0%, citomegalovirose 2,2%, vírus hepatite B 2,4%, toxoplasmose 2,8%, deficiência de alfa-1-antitripsina 13,1%, sífilis 21,1 %, auto-anticorpos hepáticos 58,4%. O trabalho desenvolvido mostra que as 8 variáveis mais decisivas, como indicadoras diferenciais entre atresia biliar e hepatite neonatal, permanecem como índices fundamentais, auxiliando, em conjunto com novos métodos diagnósticos, na composição de uma estratégia multifatorial cada vez menos invasiva e mais precisa. O estudo da etiopatogenia, dependente das condições epidemiológicas locais e da época, com a introdução de novos métodos diagnósticos, torna-se atualmente cada vez mais

  16. Acute symptomatic neonatal seizures in preterm neonates: etiologies and treatments.

    2017-12-15

    Acute symptomatic neonatal seizures in preterm newborns are a relevant clinical challenge due to the presence of many knowledge gaps. Etiology-wise, acute symptomatic seizures have an age-specific epidemiology, with intraventricular hemorrhage and its complications representing the first cause in extremely and very preterm neonates, whereas other etiologies have similar occurrence rates as in full-term infants. Specific treatment strategies for the premature neonates are not yet available. Studies suggest a similarly low response rate with even more unfavorable prognosis than in full-term infants. Pharmacodynamic and pharmacokinetic changes are likely under way during the preterm period, with the potential to affect both effectiveness and safety of antiepileptic drugs in these patients. However, due to the lack of clear evidence to guide prioritization of second-line drugs, off-label medications are frequently indicated by review papers and flow-charts, and are prescribed in clinical practice. We therefore conclude by exploring potential future lines of research. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Neonatal hyperglycemia is a metabolic disorder found in the neonatal intensive care units. Neonatal diabetes mellitus (NDM) is a very uncommon cause of hyperglycemia in the newborn, occurring in 1 in every 400,000 births. There are two subtypes of neonatal diabetes mellitus: permanent neonatal diabetes mellitus (PNDM) and transient neonatal diabetes mellitus (TNDM). We describe a term, small for gestational age, female neonate with transient neonatal diabetes mellitus who presented with poor feeding tolerance and vomiting associated with hyperglycemia (385 mg/dL), glycosuria, and metabolic acidosis within the first 12 hours of life. The neonate was treated with intravenous insulin, obtaining a slight control of hyperglycemia. An adequate glycemia was achieved at 5 weeks of life. The molecular studies showed complete loss of maternal methylation at the TND differentially methylated region on chromosome 6q24. The etiology of this neonate's hyperglycemia was a hypomethylation of the maternal TND locus. A rare cause of neonatal diabetes mellitus must be considered if a neonate presents refractory hyperglycemia. To our knowledge, this is the first case reported in Puerto Rico of transient neonatal mellitus due to the uncommon mechanism of maternal hypomethylation of the TND locus. Its prevalence in Puerto Rico is unknown.

    Purpose Hypocalcemia is a common endocrinological condition in 22q11.2 deletion syndrome. Neonatal hypocalcemia may affect neurodevelopment. We hypothesized that neonatal hypocalcemia would be associated with rare, more severe forms of intellectual disability in 22q11.2 deletion syndrome. Methods We used a logistic regression model to investigate potential predictors of intellectual disability severity, including neonatal hypocalcemia, neonatal seizures, and complex congenital heart disease, e.g., interrupted aortic arch, in 149 adults with 22q11.2 deletion syndrome. Ten subjects had moderate-to-severe intellectual disability. Results The model was highly significant (P < 0.0001), showing neonatal seizures (P = 0.0018) and neonatal hypocalcemia (P = 0.047) to be significant predictors of a more severe level of intellectual disability. Neonatal seizures were significantly associated with neonatal hypocalcemia in the entire sample (P < 0.0001), regardless of intellectual level. There was no evidence for the association of moderate- to-severe intellectual disability with other factors such as major structural brain malformations in this sample. Conclusion The results suggest that neonatal seizures may increase the risk for more severe intellectual deficits in 22q11.2 deletion syndrome, likely mediated by neonatal hypocalcemia. Neonatal hypocalcemia often remains unrecognized until the postseizure period, when damage to neurons may already have occurred. These findings support the importance of early recognition and treatment of neonatal hypocalcemia and potentially neonatal screening for 22q11.2 deletions. PMID:23765047

    2015-01-01

    Full Text Available Neonatal pustular eruption is a group of disorders characterized by various forms of pustulosis seen in first 4 weeks of life. Its presentation is often similar with some subtle differences, which can be further established by few simple laboratory aids, to arrive at a definite diagnosis. Given their ubiquitous presentation, it is sometimes difficult to differentiate among self-limiting, noninfectious, pustular dermatosis such as erythema toxicum neonatorum, transient neonatal pustular melanosis, miliaria pustulosa, etc., and potentially life threatening infections such as herpes simplex virus and varicella zoster virus infections. This review article tries to address the chronological, clinical, morphological, and histological differences among the various pustular eruptions in a newborn, in order to make it easier for a practicing dermatologist to diagnose and treat these similar looking but different entities of pustulation with a clear demarcation between the physiological benign pustular rashes and the infectious pustular lesions.

    Full Text Available Preeclampsia is a multiorgan, heterogeneous disorder of pregnancy associated with significant maternal and neonatal morbidity and mortality. Optimal strategies in the care of the women with preeclampsia have not been fully elucidated, leaving physicians with incomplete data to guide their clinical decision making. Because preeclampsia is a progressive disorder, in some circumstances, delivery is needed to halt the progression to the benefit of the mother and fetus. However, the need for premature delivery has adverse effects on important neonatal outcomes not limited to the most premature infants. Late-preterm infants account for approximately two thirds of all preterm deliveries and are at significant risk for morbidity and mortality. Reviewed is the current literature in the diagnosis and obstetrical management of preeclampsia, the outcomes of late-preterm infants, and potential strategies to optimize fetal outcomes in pregnancies complicated by preeclampsia.

    Full Text Available Christina L Boull, Kristen P Hook Department of Dermatology, Division of Pediatric Dermatology, University of Minnesota, Minneapolis, MN, USA Abstract: Neonatal erythroderma is rare, but significant as it may be the initial manifestation of an array of infectious, metabolic, and genetic conditions, some of which are life-threatening. Initial management should focus on identifying and treating life threatening etiololgies and complications, including infection, and fluid, electrolyte, and temperature disturbances. Often, the etiology of erythroderma is difficult to quickly identify in the neonate, as there is significant clinical overlap between causative entities. Furthermore, rapid definitive diagnostic tests are lacking. Herein we provide a review of the specific clinical features and diagnostic tests, which can aid in making a correct diagnosis. Skin care for the erythrodermic infant is also discussed. We encourage subspecialist consultation when appropriate to aid in the evaluation, especially when initial testing is nondiagnostic.

    Background. Newborn infants are particularly prone to hypothermia, a condition with a high mortality. Objective. To study the CT brain patterns in infants with hypothermia and neurological symptoms. Materials and methods. We reviewed the brain CT of nine infants with neonatal hypothermia, multiple organ failure, seizures and coma. Results. Two infants had normal CT scans, acutely and at follow-up, and were clinically normal at follow-up. In seven infants, CT showed diffuse cerebral oedema, with reversal of the normal density relationship between grey and white matter and a relative increased density of the thalami, brainstem and cerebellum - the 'reversal sign'. In six surviving infants with severe developmental delay, follow-up CT revealed cerebral atrophy with multicystic encephalomalacia. Conclusions. The 'reversal sign' has been described in the abused child, birth asphyxia and anoxia due to drowning. Neonatal hypothermia is offered as a further cause. (orig.)

    Jaundice is more or less common in newborn babies. Through physiological jaundice is most common cause of neonatal jaundice, possibility of obstructive jaundice especially biliary atresia should be kept in mind. Early diagnosis of biliary atresia followed by surgical treatment can save baby's life. Otherwise death is inevitable due to liver failure. Hepatobiliary scan is the imaging study of choice in neonatal jaundice especially when there is persistent conjugated hyperbilirubinaemia. Total 27 newborn babies of suspected biliary atresia, aged 14 days to 4 months were referred to Institute of Nuclear Medicine for Hepatobiliary scan. All of them had high serum bilirubin ranged from 6.0 mg/dl with an average of 9.35 ng/dl serum bilirubin level. Ultrasonography of hepatobiliary system was performed in 14 cases showing normal sized liver in 4 cases and hepatomegaly in 10 cases. Hepatobiliary scan was done with 99m Tc-Mebrofenin (Br IDA) after preparing the baby with phenobarbitone for 3-5 days. 20 (67%) cases were scan positive suggesting biliary atresia (BA) and 7(27%) cases were scan negative. In BA there will be increased hepatic uptake of the radionuclide without any significant excretion even in 24 hours delayed images. Presence of radiotracer in the bowel exclude the diagnosis of BA. Early diagnosis of biliary atresia is very important because in this condition surgery should be performed early (within 60 days of life). Studies suggest that hepatobiliary scan after hepatic stimulation with phenobarbitone for a period of 3-5 days is highly accurate for differentiating biliary atresia from other causes of neonatal jaundice. It is very important to perform hepatobiliary scan in a case of neonatal jaundice to exclude biliary atresia for the sake of baby's life.(author)

    Full Text Available Advances in neonatal management have led to considerable improvement in newborn survival. However, early (72hours onset systemic infections, both bacterial and fungal, remain a devastating complication and an important cause of morbidity and mortality in these babies. Most neonatal fungal infections are due to Candida species, particularly Candida albicans. The sources of candidiasis in NICU are often endogenous following colonization of the babies with fungi. About 10% of these babies get colonized in first week of life and up to 64% babies get colonized by 4 weeks of hospital stay. Disseminated candidiasis presents like bacterial sepsis and can involve multiple organs such as the kidneys, brain, eye, liver, spleen, bone, joints, meninges and heart. Confirming the diagnosis by laboratory tests is difficult and a high index of suspicion is required. The diagnosis of fungemia can be made definitely only by recovering the organism from blood or other sterile bodily fluid. Amphotericin B continues to be the mainstay of therapy for systemic fungal infections but its use is limited by the risks of nephrotoxicity and hypokalemia. Newer formulations of amphotericin B, namely the liposomal and the lipid complex forms, have recently become available and have been reported to have lesser toxicity. More recently Indian liposomal Amphotericin B derived from neutral lipids (L-Amp -LRC-1 has shown good response with less toxicity. A clinical trial with this preparation has shown to be safe and efficacious in neonatal fungal infections. Compared to other liposomal preparations, L-Amp-LRC-1 is effective at lower dose and is less expensive drug for the treatment of neonatal candidiasis.

    To measure the true prevalence of hearing impairment in neonates in Tafila, Jordan. This retrospective study was carried out at Prince Zeid Hospital, Taflia, Jordan through analysis of data of all births from January 2005 and January 2006. Transient evoked otoacoustic emissions (TEOAE) were measured via the application of echoprobe to both ears. There were two groups of births that were analysed statistically. Hearing impaired neonates were those with two fails or more in each ear. Normal ones were those with 3 pass or more. Of the 1788 babies in the study group, 1622 (90.7%) were enrolled in the study with 9.3% loss rate. 1512 babies were examined on the 2 day of birth, 2 of them had hearing impairment with a rate of 1.2/1000. 110 babies were screened on the day of discharge from the nursery, one of them with hearing defect with a rate of 5.9/1000. Thus, true prevalence of hearing impaiment or failure was 1.7/1000. We conclude that screening for hearing impairment in the neonatal period is easy, informative and the true prevalence of hearing impairment in Tafila is similar to that in different parts of the world.

    Full Text Available Anaerobic bacteria are well known causes of sepsis in adults but there are few studies regarding their role in neonatal sepsis. In an attempt to define the incidence of neonatal anaerobic infections a prospective study was performed during one year period. A total number of 400 neonates under sepsis study were entered this investigation. Anaerobic as well as aerobic cultures were sent. The patients were subjected to comparison in two groups: anaerobic culture positive and anaerobic culture negative and this comparison were analyzed statistically. There were 7 neonates with positive anaerobic culture and 35 neonates with positive aerobic culture. A significant statistical relationship was found between anaerobic infections and abdominal distention and pneumonia. It is recommended for those neonates with abdominal distention and pneumonia refractory to antibiotic treatment to be started on antibiotics with anaerobic coverage.

En 1996 el Centro de Prevención y Control de Enfermedades de Atlanta, el Colegio Americano de Obstetras y Ginecólogos y la Academia Americana de Pediatría sugirieron en consenso que el personal de atención de salud materna-neonatal debía adoptar una estrategia para la prevención de la sepsis por este germen. Los objetivos del presente trabajo prospectivo fueron determinar el porcentaje de colonización por SGB en las pacientes gestantes asistidas del 1° de julio de 2001 al 31 de diciembre de 2002 e implementar un programa de prevención de sepsis neonatal precoz por SGB a través de profilaxis antibiótica intraparto basado en cultivos. Sobre 1756 pacientes, se realizaron cultivos con hisopado vaginal y anal a 1228 (69.9%. El porcentaje de colonización materna por SGB fue del 1.4% (17 pacientes. Se presentó un caso de sepsis neonatal compatible con SGB (0.6‰ en una madre con cultivo negativo. Sólo una paciente portadora de SGB presentó factores de riesgo.

    Full Text Available Tomato plants are susceptible to bacterial wilting, which causes production losses varying from 10 to 100 %. A method for controlling this disease is the use of grafting on resistant rootstocks. This work had the objective of evaluating tomato genotypes for the resistance to Ralstonia solanacearum and the grafting technique as an alternative for the bacterial wilt control in the region of Recôncavo Baiano, Brazil. To evaluate the resistance to R. solanacearum, four local genotypes, collected in different regions of Bahia, the cv. Santa Clara as a susceptible treatment, and the Hawaii 7996 (H7996, as a resistant treatment were studied. For the evaluation of grafting method for control of bacterial wilt, the H7996 was used as rootstock, and the cvs. Santa Clara, Santa Cruz Kada, and Débora Plus were used as the scion plants. Both experiments were evaluated in an area infested with R. solanacearum, for a period of 65 days for the selection of the rootstocks and 45 days for the evaluation of the grafting method. Only the H7996 can be recommended as a R. solanacearum resistant rootstock. The other genotypes showed susceptibility to the pathogen. The grafting on the H7996 did not show incompatibility with the scion tomato cultivars tested and reached 100 % control of the bacterial wilt disease, for all treatments, suggesting that this method can be used as an alternative for the bacterial wilt control, allowing the production of susceptible tomato cultivars in areas infested with R. solanacearum A suscetibilidade do tomateiro à murcha bacteriana (Ralstonia solanacearum causa perdas que vão de 10 a 100 % na produção e uma das alternativas de controle que vem sendo utilizada é a enxertia com porta-enxerto resistente.

    Full Text Available BACKGROUND Neonatal conjunctivitis is eye discharge in neonates and it is a common infection in neonates in the first month of life. Worldwide, the incidence of neonatal conjunctivitis varies from 1% to 33% depending on the socioeconomic status of the people in the region. In India, the incidence varies from region to region from 0.9 to 35%. MATERIALS AND METHODS Single center prospective study. All neonates of age 0-30 days delivered and referred from neonatal ward of Chengalpattu Medical College and Hospital with complaints of eye swelling, redness, conjunctival discharge to the eye department for treatment are included in the study. RESULTS In this study, age group from 0-7 days were most commonly affected by neonatal conjunctivitis. Both eyes were commonly affected together. Neonates born by both LSCS and normal vaginal delivery were almost equally affected. The most common organism found in culture and Gram staining was staphylococci. CONCLUSION Neonatal conjunctivitis is more likely to be acquired postnatally. It acquires during the 1 st week and responds well to local application of antibiotics, which covers common causative bacteria.

    While vaccines have been tremendously successful in reducing the incidence of serious infectious diseases, newborns remain particularly vulnerable in the first few months of their life to life-threatening infections. A number of challenges exist to neonatal vaccination. However, recent advances in the understanding of neonatal immunology offer insights to overcome many of those challenges. This review will present an overview of the features of neonatal immunity which make vaccination difficult, survey the mechanisms of action of available vaccine adjuvants with respect to the unique features of neonatal immunity, and propose a possible mechanism contributing to the inability of neonates to generate protective immune responses to vaccines. We surveyed recent published findings on the challenges to neonatal vaccination and possible intervention strategies including the use of novel vaccine adjuvants to develop efficacious neonatal vaccines. Challenges in the vaccination of neonates include interference from maternal antibody and excessive skewing towards Th2 immunity, which can be counteracted by the use of proper adjuvants. Synergistic stimulation of multiple Toll-like receptors by incorporating well-defined agonist-adjuvant combinations to vaccines is a promising strategy to ensure a protective vaccine response in neonates. © 2016 S.

    Thyroid hormones have been shown to be absolutely necessary for early brain development. During pregnancy, both maternal and foetal thyroid hormones contribute to foetal brain development and maternal supply explains why most of the athyreotic newborns usually do not show any signs of hypothyroidism at birth. Foetal and/or neonatal hypothyroidism is a rare disorder. Its incidence, as indicated by neonatal screening, is about 1:4000. Abnormal thyroid development (i.e. agenesia, ectopic gland, hypoplasia) or inborn errors in thyroid hormone biosynthesis are the most common causes of permanent congenital hypothyroidism. Recent studies reported that mutations involving Thyroid Transcriptor Factors (TTF) such as TTF-1, TTF-2, PAX-8 play an important role in altered foetal thyroid development. Deficiency of transcriptor factor (Pit-1, Prop-1, LHX-3) both in mother and in the foetus represents another rare cause of foetal hypothyroidism. At birth clinical picture may be not always so obvious and typical signs appear only after several weeks but a delayed diagnosis could have severe consequences consisting of delayed physical and mental development. Even if substitutive therapy is promptly started some learning difficulties might still arise suggesting that intrauterine adequate levels of thyroid hormones are absolutely necessary for a normal neurological development. Placental transfer of maternal antithyroid antibodies inhibiting fetal thyroid function can cause transient hypothyroidism at birth. If the mother with thyroid autoimmune disease is also hypothyroid during pregnancy and she doesn't receive substitutive therapy, a worse neurological outcome may be expected for her foetus. Foetal and/or neonatal hyperthyroidism is a rare condition and its incidence has been estimated around 1:4000-40000, according to various authors. The most common causes are maternal thyroid autoimmune disorders, such as Graves' disease and Hashimoto's thyroiditis. Rarer non autoimmune causes

    Full Text Available Dental plaque removal is an important issue in health promotion. Toothbrushing is one of the main methods employed for such purpose, since it can prevent dental caries by means of the fluoride present in the dentifrice. Dentifrices might contain plaque disclosing agents and thus allow dental plaque observation. The aim of this study was to assess whether utilization of a plaque disclosing agent interfered with plaque removal among adolescents, as well as the difference between utilization of erythrosine tablets and dentifrices containing plaque disclosing agent. The sample was composed of 62 students from Piracicaba, SP, Brazil, aged 12 to 14 years old, divided into 3 groups: G1 or control group (toothbrushing without plaque disclosure; G2 (plaque disclosing with an erythrosine tablet and toothbrushing and G3 (toothbrushing with dentifrice containing plaque disclosing agent. After toothbrushing, disclosure of the remaining dental plaque was performed in all groups with a fuchsin tablet and measured through the Simplified Oral Health Assessment Index (OHI-S, in two stages with a 2-month interval between them. The analysis of variance (ANOVA showed that there was no difference in the OHI-S index between the groups (p>0.05, however the G3 displayed a higher proportion of students with plaque reduction (23% than G2 (21%, besides the smallest difference in the mean remaining dental plaque. There was no difference between groups; however, it was suggested that the dentifrice with plaque disclosing agent had positive results in relation to the erythrosine tablet, even though the small sample size may have interfered with the results, indicating the need of complementary studies.Na promoção de saúde, a remoção da placa bacteriana é um fator importante e um dos métodos que incentivam sua remoção, é a escovação dentária, podendo-se prevenir a cárie dental através do íon flúor dos dentifrícios.

    To determine the nature and frequency of painful procedures and procedural pain management practices in neonatal units in Kenya. Cross-sectional survey. Level I and level II neonatal units in Kenya. Ninety-five term and preterm neonates from seven neonatal units. Medical records of neonates admitted for at least 24 h were reviewed to determine the nature and frequency of painful procedures performed in the 24 h period preceding data collection (6:00 to 6:00) as well as the pain management interventions (eg, morphine, breastfeeding, skin-to-skin contact, containment, non-nutritive sucking) that accompanied each procedure. Neonates experienced a total of 404 painful procedures over a 24 h period (mean=4.3, SD 2.0; range 1-12); 270 tissue-damaging (mean=2.85, SD 1.1; range 1-6) and 134 non-tissue-damaging procedures (mean=1.41, SD 1.2; range 0-6). Peripheral cannula insertion (27%) and intramuscular injections (22%) were the most common painful procedures. Ventilated neonates and neonates admitted in level II neonatal units had a higher number of painful procedures than those admitted in level I units (mean 4.76 vs 2.96). Only one procedure had a pain intensity score documented; and none had been performed with any form of analgesia. Neonates in Kenya were exposed to numerous tissue-damaging and non-tissue-damaging procedures without any form of analgesia. Our findings suggest that education is needed on how to assess and manage procedural pain in neonatal units in Kenya. Published by the BMJ Publishing Group Limited.

    Full Text Available Background: Jaundice is a common condition among neonates. Prolonged unconjugated hyperbilirubinemia occurs when jaundice persists beyond two weeks in term neonates and three weeks in preterm neonates. This study aimed to determine the etiologies of prolonged unconjugated hyperbilirubinemia in infants admitted to the neonatal ward of Besat Hospital in Hamadan, Iran. Methods: This study was conducted on all infants diagnosed with prolonged unconjugated hyperbilirubinemia during 2007-2012 in the neonatal ward of Besat Hospital in Hamadan, Iran. Demographic characteristics of infants, physical examination and laboratory findings were collected and analyzed to determine the etiologies of neonatal hyperbilirubinemia. Results: In total, 100 infants diagnosed with neonatal hyperbilirubinemia were enrolled in this study, including 49 male and 51 female neonates with mean age of 20±1 days and mean bilirubin level of 17.5±4.0 mg/dL. Main causes of hyperbilirubinemia were urinary tract infection, ABO incompatibility, hypothyroidism and glucose-6-phosphate dehydrogenase deficiency in 14%, 5%, 6% and 5% of neonates, respectively. Moreover, unknown etiologies, such as breastfeeding, were detected in 70% of the studied infants. Conclusion: According to the results of this study, determining the main causes of prolonged unconjugated hyperbilirubinemia in neonates is of paramount importance. In the majority of cases, neonatal hyperbilirubinemia is associated with physiological factors, such as breastfeeding.

    2006-01-01

    Imaging of the central nervous system is one of the major tasks of Paediatric Radiology, particularly in newborns, who present with a variety of conditions that need more or less urgent imaging. Imaging is usually performed primarily by bedside US, in rare cases supplemented by a skull or spine radiograph. For more detailed information and preoperatively, MRI has become the neuroimaging tool. Thus, CT today is only used for acute trauma assessment, for assessment of potential cerebral calcifications or when MRI is not available. In cases with vascular anomalies or unsuccessful punctures, image guided interventions (embolisation) or image guidance for access (lumbar puncture, puncture of skull collections ...) may become necessary. This article tries to give a brief overview on the common disease entities, their typical imaging features in the major modalities applied and the implications of imaging potential for indication and choice of imaging method. In general, acute assessment may become everywhere and major features of important diseases should be recognised not to miss conditions which need urgent treatment or referral to a dedicated paediatric unit. Many other conditions will only be seen at centres with a dedicated neonatal care unit and dedicated paediatric radiologist who then also will be able to provide proper imaging with adapted protocols and methods for these partially severely sick babies. As these specific features and adapted capabilities as well as dedicated training and clinical experience are necessary for providing best results and proper handling in neonates, many neonatal conditions will not be imaged at a peripheral site, but primarily should be referred to a paediatric (radiology) centre

    2006-10-01

    Full Text Available Abstract Foetal/neonatal alloimmune thrombocytopaenia (NAIT results from maternal alloimmunisation against foetal platelet antigens inherited from the father and different from those present in the mother, and usually presents as a severe isolated thrombocytopaenia in otherwise healthy newborns. The incidence has been estimated at 1/800 to 1/1 000 live births. NAIT has been considered to be the platelet counterpart of Rh Haemolytic Disease of the Newborn (RHD. Unlike RHD, NAIT can occur during a first pregnancy. The spectrum of the disease may range from sub-clinical moderate thrombocytopaenia to life-threatening bleeding in the neonatal period. Mildly affected infants may be asymptomatic. In those with severe thrombocytopaenia, the most common presentations are petechiae, purpura or cephalohaematoma at birth, associated with major risk of intracranial haemorrhage (up to 20% of reported cases, which leads to death or neurological sequelae. Alloimmune thrombocytopaenia is more often unexpected and is usually diagnosed after birth. Once suspected, the diagnosis is confirmed by demonstration of maternal antiplatelet alloantibodies directed against a paternal antigen inherited by the foetus/neonate. Post-natal management involves transfusion of platelets devoid of this antigen, and should not be delayed by biological confirmation of the diagnosis (once the diagnosis is suspected, especially in case of severe thrombocytopaenia. Prompt diagnosis and treatment are essential to reduce the chances of death and disability due to haemorrhage. Due to the high rate of recurrence and increased severity of the foetal thrombocytopaenia in successive pregnancies, antenatal therapy should be offered. However, management of high-risk pregnancies is still a matter of discussion.

    Herpes simplex virus (HSV) 1 and HSV-2 infections are highly prevalent worldwide and are characterized by establishing lifelong infection with periods of latency interspersed with periodic episodes of reactivation. Acquisition of HSV by an infant during the peripartum or postpartum period results in neonatal HSV disease, a rare but significant infection that can be associated with severe morbidity and mortality, especially if there is dissemination or central nervous system involvement. Diagnostic and therapeutic advances have led to improvements in mortality and, to a lesser extent, neurodevelopmental outcomes, but room exists for further improvement. Copyright © 2015 Elsevier Inc.

    2016-01-01

    Past studies have clearly shown the existence of a spectrum of endometrial progesterone responses in neonatal endometrium, varying from proliferation to full decidualization with menstrual-like shedding. The bleedings represent, similar to what occurs in adult menstruation, a progesterone withdrawal bleeding. Today, the bleeding is completely neglected and considered an uneventful episode of no clinical significance. Yet clinical studies have linked the risk of bleeding to a series of events indicating fetal distress. The potential link between the progesterone response and major adolescent disorders requires to be investigated by prospective studies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2014-09-01

    The management of infants born with myelomeningocele depends on understanding how their bladder stores and empties urine. Storage at low pressure with effective emptying periodically throughout the day is the goal. Intervention is designed to impact on one or both of these processes so that infants can remain infection-free and at the same time allow for appropriate renal growth over time. Urodynamic evaluation plays an important role, so that neonates can be stratified according to their risk. Most patients require intermittent catheterization and pharmacotherapy to achieve these goals at some point in their lives. Copyright © 2014 Elsevier Inc. All rights reserved.

    2004-01-01

    Objective: To determine the number of cases and manifestations of thrombocytopenia in sick neonates. Subjects and Methods: A total of 365 neonates from 0-28 days of age admitted with different clinical problems irrespective of birth weight and gestational age were evaluated for thrombocytopenia. These neonates were categorized into five different groups (A-E), which were of neonatal infections, asphyxia neonatorum, preterm and smallness for gestational age, jaundice and miscellaneous respectively. Results: Out of 365 cases, 88 were found to have thrombocytopenia (platelet counts < 150,000 per mm/sup 3/) which was 24.1% of the total. In group A (neonatal infections), out of 152 neonates, 62 had low platelet counts (40.78%). In group B (neonatal asphyxia), out of 90 only 11 had thrombocytopenia (12.2%). In group C (preterm and small for gestational age), out of 60 cases only 9 had thrombocytopenia. In group D (jaundice), all 33 cases had normal platelet counts. In group E (miscellaneous), out of 30 cases only 6 had thrombocytopenia. The common manifestations in thrombocytopenic babies were petechiae and bruises followed by gastrointestinal hemorrhages. The percentage of manifest thrombocytopenia cases was 56.8% and of occult thrombocytopenia 43.1 %. Conclusion: The leading causes of thrombocytopenia in sick neonates are infections, asphyxia, complicated pre- maturity and smallness for gestational age. Apart from the platelet counts the bleeding mainfestations also depend upon the underlying ailments. (author)

    The principles of clinical pharmacology also apply to neonates, but their characteristics warrant a tailored approach. We focus on aspects of both developmental pharmacokinetics (concentration/time relationship) and developmental pharmacodynamics (concentration/effect relationship) in neonates. We hereby aimed to link concepts used in clinical pharmacology with compound-specific observations (anti-epileptics, analgosedatives) in the field of neonatal neurology. Although in part anecdotal, we subsequently illustrate the relevance of developmental pharmacology in the field of neonatal neurology by a specific intervention (e.g. whole body cooling), specific clinical presentations (e.g. short and long term outcome following fetal exposure to antidepressive agents, the development of new biomarkers for fetal alcohol syndrome) and specific clinical needs (e.g. analgosedation in neonates, excitocytosis versus neuro-apoptosis/impaired synaptogenesis).

    A 1-week-old infant was brought to a regional hospital with a history of recurrent seizures following lower abdominal septic skin infection. She was found to have neonatal tetanus, and a spatula test was positive. The tetanus infection was associated with a superficial skin infection, common in neonates. Treatment included sedatives (diazepam, chlorpromazine, phenobarbitone and morphine), muscle relaxants, antibiotics and ventilation in the neonatal intensive care unit. Intrathecal and intramuscular immunoglobulin were given, and the wound was treated. The infant recovered, with no seizures by the 16th day from admission, and was off the ventilator by the 18th day. This was shorter than the usual 3 - 4 weeks for neonates with tetanus at the hospital. The question arises whether tetanus immunisation should be considered in infants with skin infections, which frequently occur in the neonatal period.

    Fifteen patients with persistent neonatal jaundice were evaluated by sonography and radionuclide scintigraphy. The sonographic features of both neonatal hepatitis and biliary atresia are nonspecific. Hepatobiliary scintigraphy after phenobarbital pretreatment in patients with neonatal hepatitis demonstrates normal hepatic extraction and delayed tracer excretion into the gastrointestinal tract. If there is neonatal hepatitis with severe hepatocellular damage, the hepatic extraction of tracer activity is decreased and excretion may be delayed or absent. Patients under 3 months of age with biliary atresia have normal hepatic extraction of tracer with no excretion into the gastrointestinal tract. Sonography in patients with a choledochal cyst shows a cystic mass in the porta hepatis with associated bile-duct dilatation. Hepatobiliary scintigraphy confirms that the choledochal cyst communicates with the biliary system. Initial sonography demonstrates hepatobiliary anatomy; subsequent phenobarbital-enhanced radionuclide scintigraphy determines hepatobiliary function. An expedient diagnostic approach is recommended for the evaluation of persistent neonatal jaundice

    Full Text Available Abstract Background Analgesia for neonatal circumcision was recently advocated for every male infant, and its use is considered essential by the American Academy of Pediatrics. We compared the post-operative analgesic quality of bupivacaine to that of lidocaine for achieving dorsal penile nerve block (DPNB when performing neonatal circumcision. Methods Data were obtained from 38 neonates following neonatal circumcision. The infants had received DPNB analgesia with either lidocaine or bupivacaine. The outcome variable was the administration by the parents of acetaminophen during the ensuing 24 hours. Results Seventeen infants received lidocaine and 19 received bupivacaine DPNB. Ten infants in the lidocaine group (59% were given acetaminophen following circumcision compared to only 3 (16% in the bupivacaine group (P 2 = 20.6; P = 0.006. Conclusion DPNB with bupivacaine for neonatal circumcision apparently confers better analgesia than lidocaine as judged by the requirement of acetaminophen over the ensuing 24-hour period.

Due to the frequent need for resuscitation at birth, it is vital to have evidence-based care guidelines and to provide effective neonatal resuscitation training. Every five years, the International Liaison Committee on Resuscitation (ILCOR reviews the science of neonatal resuscitation. In the US, the American Heart Association (AHA develops treatment guidelines based on the ILCOR science review, and the Neonatal Resuscitation Program (NRP translates the AHA guidelines into an educational curriculum. In this report, we review recent advances in neonatal resuscitation training and practice. We begin with a review of the new 7th edition NRP training curriculum. Then, we examine key changes to the 2015 AHA neonatal resuscitation guidelines. The four components of the NRP curriculum reviewed here include eSim®, Performance Skills Stations, Integrated Skills Station, and Simulation and Debriefing. The key changes to the AHA neonatal resuscitation guidelines reviewed include initial steps of newborn care, positive-pressure ventilation, endotracheal intubation and use of laryngeal mask, chest compressions, medications, resuscitation of preterm newborns, and ethics and end-of-life care.

    Lung disease represents one of the most life-threatening conditions in prematurely born children. In the evaluation of the neonatal chest, the primary and most important diagnostic study is therefore the chest radiograph. Since prematurely born children are very sensitive to radiation, those radiographs may lead to a significant radiation detriment. Hence, knowledge of the patient dose is necessary to justify the exposures. A study to assess the patient doses was started at the neonatal intensive care unit (NICU) of the Univ. Hospital in Leuven. Between September 2004 and September 2005, prematurely born babies underwent on average 10 X-ray examinations in the NICU. In this sample, the maximum was 78 X-ray examinations. For chest radiographs, the median entrance skin dose was 34 μGy and the median dose area product was 7.1 mGy.cm 2 . By means of conversion coefficients, the measured values were converted to organ doses. Organ doses were calculated for three different weight classes: extremely low birth weight infants ( 2500 g). The doses to the lungs for a single chest radiograph for infants with extremely low birth weights, low birth weights and normal birth weights were 24, 25 and 32 μGy, respectively. (authors)

    Respiratory syncytial virus (RSV) is the leading cause of bronchiolitis in infants. Palivizumab is an immunoprophylactic agent for RSV prevention in preterm infants and those with neonatal chronic lung disease. This study examines its use across neonatal units in Ireland. A questionnaire was administered to one Consultant Neonatologist or Paediatrician in each of the 20 maternity centres in Ireland about their guidelines for Palivizumab administration. There is variation in administration of Palivizumab with little consistency found between protocols reported in terms of age and presence of chronic lung disease. Ten centres have in house protocols, 3 centres use the American Academy of Paediatrics (AAP) guidelines, 2 centres prefer the UK Joint Committee on Vaccination and Immunisation (JCVI) guidelines and 3 centres do not have a set protocol. Four participants felt its use has impacted on hospital admissions and 61% believe its use is cost effective. The budgetary implication for immunoprophylaxis with Palivizumab in Ireland is estimated at 1.5 to 2 million euros annually. Given current pharmacoeconomic constraints there is a need to implement a national protocol on RSV immunoprophylaxis.

    Neonatal transport teams comprise multidisciplinary health care providers who are skilled in patient care, communication and customer service, and equipment mechanics. They are extensively trained in resuscitation and stabilization, preparing for accelerating care, and their focus is preservation of life. In any situation focused on caring for critically ill patients, ethical issues and questions may arise. For instance, is it compassionate and/or cost-effective to separate mothers and infants when continuing/accelerating care is futile, and when and how should care be redirected from acute and lifesaving care to comfort care and bereavement support for the family? The knowledge and skills required to address such situations and communicate and participate in a redirection of care may not be adequately emphasized in the preparation of the professionals responsible for stabilizing and transporting critically ill newborns. This article raises issues relating to transport and redirecting care such as eligibility for transport, parental request and consent, separation of mothers and infants, palliative and bereavement care, ethical considerations, competitive transport environment, and customer service. A shared mental model is essential. The focus of this article is not to provide answers to all of these issues, but to highlight the complexity of the topic of redirecting treatment during neonatal transport. Redirecting treatment needs to be discussed, and health care professionals should be prepared during their transport team training. Each family and situation must be approached individually, with the acceptance that there will always be more questions than answers.

    Advances in cardiology, surgical techniques, postoperative care, and medications have improved the chances of long-term survival of the neonatal and pediatric patient with complex congenital cardiac anomalies. Rather than undergoing palliative repair, these children are now frequently taken to the operating room for complete repair. As complete repair becomes the norm, collaborative management and a thorough understanding of the pre and postoperative medications used become essential to the care of these patients. The nurse's ability to understand preop, postop, and management medications is enhanced by an understanding of the principles of cardiac anatomy and physiology, as well as developmental changes in cardiac function. All of these are reviewed. In addition, since the safe and effective administration of these drugs depends on the pediatric intensive care unit (PICU) and neonatal intensive care unit (NICU) nurse's thorough knowledge of these medications and their effects on the cardiovascular system, a brief review of these medications is presented. While new technology and techniques are improving survival rates for children with congenital heart anomalies, it is the postoperative care that these children receive that enhances the patient's survival even more.

    Full Text Available Background: Neonatal pain management has received increasing attention over the past four decades. Research into the effects of neonatal pain emphasises the professional, ethical and moral obligations of staff to manage pain for positive patient outcomes. However, evaluation studies continuously report evidence of inadequate neonate pain management and a gap between theory and practice. Objective: This study reviewed current practice in neonatal pain management to describe the knowledge, attitudes and practices of nurses and doctors regarding pain management for neonates in two academic hospitals. Method: A non-experimental, prospective quantitative survey, the modified Infant Pain Questionnaire, was used to collect data from 150 nurses and doctors working in the neonatal wards of two academic hospitals in central Gauteng. Results: The response rate was 35.33% (n = 53, most respondents being professional nurses (88.68%; n = 47 working in neonatal intensive care units (80.77%; n = 42; 24 (45.28% had less than 5 years’ and 29 respondents 6 or more years’ working experience in neonatal care. A review of pain management in the study setting indicated a preference for pharmacological interventions to relieve moderate to severe pain. An association (p < 0.05 was found between pain ratings on 5 procedures and frequency of administration of pharmacological pain management. Two-thirds of respondents (64% reported that there were no pain management guidelines in the neonatal wards in which they worked. Conclusion: The interventions to manage moderate neonatal pain are in line with international guidelines. However, neonatal pain management may not occur systematically based on prior assessment of neonatal pain, choice of most appropriate intervention and evaluation. This study recommends implementation of a guideline to standardise practice and ensure consistent and adequate pain management in neonates.

    Full Text Available OBJECTIVE: This study was a literature review with the purpose of analyzing articles comparing early and late mobilization and those comparing early and late discharge for patients with acute myocardial infarction. METHODS: The literature review was performed using the Lilacs and Medline databases (1966-2007, and the length of the resting period, the hospitalization and possible complications were analyzed. RESULTS: We selected 18 articles; 11 of them compared early and late mobilization and 7 compared early and late discharge. The length of the resting period in the early mobilization group varied from 2 to 10 days and 5 to 28 days for the longest resting period. The early discharge group stayed in the hospital from 3 to 14 days and the late discharge group stayed in the hospital from 5 to 21 days. CONCLUSION: The studies show that there is no evidence of complications related to short periods of bed rest and hospitalization.OBJETIVO: Analizar los artículos que comparaban la movilización precoz con la tardía, así como aquellos que comparaban el alta precoz con la tardía en pacientes con infarto agudo del miocardio.

    Full Text Available La resistencia bacteriana es un problema de salud pública causante de índices elevados de morbi-mortalidad hospitalaria. En la medida en que se usan los diferentes antibióticos se seleccionan bacterias resistentes a múltiples fármacos. El desarrollo de nuevas herramientas moleculares de la genómica y proteómica, como el PCR en tiempo real, pirosecuenciación de ADN, espectrometría de masas, microarreglos de ADN y bioinformática, permite conocer en forma más estrecha la fisiología y estructura de las bacterias y los mecanismos de resistencia a los antibióticos. Estos estudios hacen posible identificar nuevos blancos farmacológicos y diseñar antibióticos específicos para suministrar tratamientos más certeros que combatan las infecciones producidas por bacterias. Con estas técnicas también es posible la identificación rápida de los genes que confieren la resistencia a los antibióticos y el reconocimiento de las estructuras genéticas complejas como los integrones, que intervienen en la diseminación de los genes que producen la multirresistencia.Bacterial resistance is a public health problem causing high rates of morbidity and mortality in hospital settings. To the extent that different antibiotics are used, bacteria resistant to multiple drugs are selected. The development of new molecular genomic and proteomic tools such as real-time PCR, DNA pyrosequencing, mass spectrometry, DNA microarrays, and bioinformatics allow for more in-depth knowledge about the physiology and structure of bacteria and mechanisms involved in antibiotic resistance. These studies identify new targets for drugs and design specific antibiotics to provide more accurate treatments to combat infections caused by bacteria. Using these techniques, it will also be possible to rapidly identify genes that confer resistance to antibiotics, and to identify complex genetic structures, such as integrons that are involved in the spread of genes that confer

    This paper describes our leading experience in the clinical application of laser in the treatment of neonatal jaundice. Currently, the irradiation of jaundiced infants during neonatal life to fluorescent light is the most common treatment of neonatal hyperbilirubinemia. The authors have investigated the photodegradation of bilirubin by laser in vitro and in Gunn rats before embarking on its clinical application in the treatment of jaundice in the new born child. This work was done to study the theraputic effect of laser compared to the currently used phototherapy in the treatment of neonatal jaundice. We selected 16 full term neonates with jaundice to be the subject of this study. The neonates of the study were devided into two groups. The first group was treated with continuous phototherapy . The second group recieved photoradiation therapy with gas laser The laser used was a CW argon-ion laser tuned to oscillate at 488.0 nm wavelength. This wavelength selection was based on our previous studies on the effect of laser irradiation of Gunn rats at different wavelengths. Comparison of the results of both methods of treatment will be reported in detail. The advantages and limitations of laser photoradiation therapy for neonatal jaundice will be discussed.

    Antibiotics are often used in neonates despite the absence of relevant dosing information in drug labels. For neonatal dosing, clinicians must extrapolate data from studies for adults and older children, who have strikingly different physiologies. As a result, dosing extrapolation can lead to increased toxicity or efficacy failures in neonates. Driven by these differences and recent legislation mandating the study of drugs in children and neonates, an increasing number of pharmacokinetic studies of antibiotics are being performed in neonates. These studies have led to new dosing recommendations with particular consideration for neonate body size and maturation. Herein, we highlight the available pharmacokinetic data for commonly used systemic antibiotics in neonates.

    Advances in neonatal intensive care, total parenteral nutrition and improvements in technology have led to a greatly improved outcome of neonatal surgery in developed countries. In many parts of sub-Saharan Africa, however, neonatal surgery continues to pose wide-ranging challenges. Delivery outside hospital, delayed referral, poor transportation, and lack of appropriate personnel and facilities continue to contribute to increased morbidity and mortality in neonates, particularly under emergency situations. Antenatal supervision and hospital delivery needs to be encouraged in our communities. Adequate attention needs to be paid to providing appropriate facilities for neonatal transport and support and training of appropriate staff for neonatal surgery. Neonates with surgical problems should be adequately resuscitated before referral where necessary but surgery should not be unduly delayed. Major neonatal surgery should as much as possible be performed by those trained to operate on neonates. Appropriate research and international collaboration is necessary to improve neonatal surgical care in the environment.

    Full Text Available Abstract Background Neonatal mortality accounts for almost 40 per cent of under-five child mortality, globally. An understanding of the factors related to neonatal mortality is important to guide the development of focused and evidence-based health interventions to prevent neonatal deaths. This study aimed to identify the determinants of neonatal mortality in Indonesia, for a nationally representative sample of births from 1997 to 2002. Methods The data source for the analysis was the 2002–2003 Indonesia Demographic and Health Survey from which survival information of 15,952 singleton live-born infants born between 1997 and 2002 was examined. Multilevel logistic regression using a hierarchical approach was performed to analyze the factors associated with neonatal deaths, using community, socio-economic status and proximate determinants. Results At the community level, the odds of neonatal death was significantly higher for infants from East Java (OR = 5.01, p = 0.00, and for North, Central and Southeast Sulawesi and Gorontalo combined (OR = 3.17, p = 0.03 compared to the lowest neonatal mortality regions of Bali, South Sulawesi and Jambi provinces. A progressive reduction in the odds was found as the percentage of deliveries assisted by trained delivery attendants in the cluster increased. The odds of neonatal death were higher for infants born to both mother and father who were employed (OR = 1.84, p = 0.00 and for infants born to father who were unemployed (OR = 2.99, p = 0.02. The odds were also higher for higher rank infants with a short birth interval (OR = 2.82, p = 0.00, male infants (OR = 1.49, p = 0.01, smaller than average-sized infants (OR = 2.80, p = 0.00, and infant's whose mother had a history of delivery complications (OR = 1.81, p = 0.00.

    In newborn infants, normal adrenal glands are characterized by a relatively thin echogenic center surrounded by a thick, hypoechoic cortical rim as seen on ultrasound (US). Various disorders involving the neonatal adrenal gland include adrenal hemorrhage, hyperplasia, cyst, Wolman's disease, and congenital neuroblastoma. Adrenal hemorrhage is the most common cause of an adrenal mass in the neonate, though differentiation between adrenal hemorrhage and neuroblastoma is in many cases difficult.

    Intrathoracic stomach is a rare and serious congenital abnormality. The anomaly may be complicated by gastric volvulus and can lead to ischemic gastric infarction in the neonate. If diagnosed antenatally, neonatal management can be planned in advance so as to reduce morbidity. This anomaly must be differentiated from the more common congenital diaphragmatic hernia, as associated pulmonary hypoplasia is common in the latter and rare with gastric herniation. We report a case of intrathoracic stomach in a neonate without volvulus, fortunately a rare entity which was managed operatively, and the child has been under regular follow-up.

    Studies on pharmacokinetics and clinical effects of flomoxef (FMOX), a parenteral oxacephem antibiotic, were carried out in neonates. The results obtained are summarized as follows. 1. Mean peak serum concentrations of FMOX upon single administrations at doses of 20 mg/kg and 40 mg/kg were 33.3 +/- 7.33 micrograms/ml and 68.9 micrograms/ml, respectively. 2. Mean urinary recovery rates of FMOX in the first 6 hours after administration of the above doses were 35.2% and 48.3%, respectively. 3. FMOX was administered to 4 cases including 1 prophylactic case, 1 case each with aspiration pneumonia and sepsis, hypodermic abscess of the head, and itrauterine infection, at a dose of 20-30 mg/kg 2 or 3 times a day. Clinically, excellent results were obtained in 3 cases including an methicillin-resistant Staphylococcus aureus case. 4. No side effects nor abnormal laboratory test results were observed.

    In this case report the authors present an extremely low birth weight premature infant with neonatal brucellosis whose mother had been treated for brucellosis during pregnancy. Infant developed mild respiratory distress syndrome soon after birth. At 2nd wk of postnatal age findings of bronchopulmonary dysplasia were evident and she and her mother were diagnosed to have brucellosis at the same time. After commencement of antibrucellosis therapy and nonspesific treatment for bronchopulmonary dysplasia, infant was completely cured of the symptoms related to both brucellosis and bronchopulmonary dysplasia. The results of the present case and a review of the literature have let to conclude that Brucella might have role in development of prematurity and bronchoplumonary dysplasia. Since discovery of brucella bacilli in early periods of 20th century, fetotoxicity of brucella bacilli seems to increase gradually suggesting an increasing virulance of the bacilli or vanishing host defense of human beings.

    1988-01-01

    We have seen 10 newborn babies who developed respiratory distress and whose chest radiographs showed a miliary nodular pattern of disease. Of these infants only 3 had blood cultures that were positive for staphylococcus aureus. Of the remaining 7, 2 had conjunctivitis from which staphylococcus aureus was cultured, 4 had negative cultures and 1 did not have a blood culture done. All patients were diagnosed as having bacterial pneumonia and appeared to respond favourably to antibiotic therapy. The pulmonary abnormalities resolved. The children were clinically well in less than 3 weeks. The author suggests that the miliary pattern is one of the radiological patterns of neonatal pneumonia possibly produced by hematogenous bacterial dissemination. (orig.)

    Acute neonatal parotitis (ANP) is a rare condition, characterised by parotid swelling and other local inflammatory signs. The most common pathogen is Staphylococcus aureus, but other organisms can be implicated. We describe the case of a 13-day-old term newborn, previously healthy, with late-onset group B Streptococcus (GBS) bacteraemia with ANP, who presented with irritability, reduced feeding and tender swelling of the right parotid. Laboratory evaluation showed neutrophilia, elevated C reactive protein and procalcitonin, with normal serum amylase concentration. Ultrasound findings were suggestive of acute parotitis. Empiric antibiotic therapy was immediately started and adjusted when culture results became available. The newborn was discharged after 10 days, with clinical improvement within the first 72 h. Although S. aureus is the most common pathogen implicated in ANP, GBS should be included in the differential diagnosis. 2015 BMJ Publishing Group Ltd.

    Various aspects of the thyroid function have been measured in 28 cases of neonatal hypothyroidism detected by means of the Quebec Screening Program for Metabolic Diseases. In all instances the T4 value in the blood of filter paper spot was below 2 SD of the mean of the day, averaging 0.39 +/- 0.04 ng/40 mul (mean +/- SEM) of eluted blood. The T4 value of a second similar sample averaged 0.22 +/- 0.04 ng/mul of eluted blood; this value was significantly lower than the first one. The serum T4 concentration was decreased in all the infants, whereas three of them had a normal serum TSH concentration. At least three groups of patients could be identified: (1) patients with primary thyroid failure, (2) those with secondary or tertiary hypothyrodism, and (3) those with abnormal synthesis of thyroid hormone.

    Full Text Available O objetivo do presente artigo é revisar a literatura acerca dos conhecimentos atuais relativos à terapia nutricional - enteral e parenteral - para os recém-nascidos pré-termo, principalmente os de muito baixo peso, destacando seu efeito protetor na sepse neonatal e na enterocolite necrosante. As diferentes modalidades de alimentação do recém-nascido prematuro - especialmente para aqueles de muito baixo peso - e seu efeito protetor na diminuição de complicações (mormente as infecciosas foram analisadas. A utilização preferencial do leite materno na nutrição enteral, o controle das ofertas energético-protéicas, o início precoce da nutrição enteral mínima, a introdução precoce da alimentação parenteral - nas primeiras 24 horas - e a utilização dos imunonutrientes que tenham estudos suficientes para fundamentar sua indicação podem se constituir em boas diretrizes adjuvantes na prevenção da sepse neonatal e da enterocolite necrosante. Sem embargo, percebe-se a necessidade de mais estudos - preferencialmente multicêntricos, controlados e randomizados - para esclarecer o papel protetor da nutrição no RNPT, não somente na prevenção de infecções, mas também para auxiliar o desenvolvimento neural e a prevenção de consequências deletérias futuras.

    Full Text Available OBJECTIVE: To describe HRCT findings in patients with bacterial pneumonia following bone marrow transplantation (BMT. METHODS: This was a retrospective study involving 30 patients diagnosed with bacterial pneumonia in whom HRCT of the chest was performed within 24 h after the onset of symptoms and the diagnosis was confirmed, based on a positive culture of sputum or bronchial aspirate, together with a positive pleural fluid or blood culture, within one week after symptom onset. There were 20 male patients and 10 female patients. The median age was 21 years (range, 1-41 years. The BMT had been performed for the treatment of the following: chronic myeloid leukemia, in 14 cases; severe aplastic anemia, in 6; acute myeloid leukemia, in 4; Fanconi's anemia, in 3; and acute lymphocytic leukemia, in 3. Two radiologists analyzed the HRCT scans and reached their final decisions by consensus. RESULTS: The most common HRCT findings were air-space consolidation (in 60%, small centrilobular nodules (in 50%, ground-glass opacities (in 40%, bronchial wall thickening (in 20%, large nodules (in 20%, pleural lesions (in 16.7% and tree-in-bud opacities (in 10%. The pulmonary lesions were distributed in the central and peripheral areas in 15 patients, whereas they were exclusively peripheral in 11. Lesions were located in the lower and middle lobes of the lung in 22 and 20 patients, respectively. CONCLUSIONS: The most common HRCT findings in our patient sample were air-space consolidation, small centrilobular nodules and ground-glass opacities, most often in the central and peripheral regions of the middle and lower lung zones.OBJETIVO: Descrever os achados de TCAR em pacientes com pneumonia bacteriana após transplante de medula óssea (TMO.

    The aim of this study was to investigate the frequency and type of X ray examinations performed on neonates classified according to their birth weight in a neonatal intensive care unit (NICU). In this study, the radiology records of 2408 neonates who were admitted to the NICU of Oita Prefectural Hospital between January 1994 and September 1999 were investigated. This study revealed that the neonates with earlier gestational ages and lower birth weights required longer NICU stays and more frequent X ray examinations made using a mobile X ray unit. The average number of X ray examinations performed on neonates of less than 750 g birth weight was 26 films per neonate. In regard to computed tomography and fluoroscopy, no significant relationship was found between the birth weight and number of X rays. This study revealed that the entrance-surface dose per neonate was dependent upon the birth weight, while the maximum dose was not dependent upon the birth weight. The average neonatal dose in the NICU was predominantly from computed tomography and fluoroscopy. The individual dose varied widely among neonates. (author)

    There has been a growing interest among neonatologists and paediatricians regarding identification and evaluation of hypertension in the neonatal period. Despite the emergent normative data on blood pressure values in term and preterm neonates over the last two decades, there is still controversy regarding correct definition and classification of hypertension. This article will discuss the current definitions, available normative data and etiology of neonatal hypertension. There is paucity of records in terms of efficacy of antihypertensive drugs in this specific population and management is usually experience based, causing considerable heterogeneity amongst different units. This review article will also cover the evaluation, management, outcomes and follow up of neonatal hypertension with latest advances in this field.

    Fetal and neonatal hyperthyroidism may occur in mothers with Graves’ disease. Fetal thyrotoxicosis manifestation is observed with the transition of TSH receptor stimulating antibodies to the fetus from the 17th–20th weeks of pregnancy and with the fetal TSH receptors becoming responsive after 20 weeks. The diagnosis is confirmed by fetal tachycardia, goiter and bone age advancement in pregnancy and maternal treatment is conducted in accordance. The probability of neonatal hyperthyroidism is high in the babies of mothers that have ongoing antithyroid requirement and higher antibody levels in the last months of pregnancy. Clinical manifestation may be delayed by 7–17 days because of the antithyroid drugs taken by the mother. Neonatal hyperthyroidism symptoms can be confused with sepsis and congenital viral infections. Herein, the diagnosis and therapeutic approach are reviewed in cases of fetal neonatal hyperthyroidism. PMID:28439194

    In this article, the sensorineural hearing loss is presented as a possible sequelae of neonatal hyperbilirubinemia. In our program of early hipoacusia detection, 241 babies were examined from January 1996 until November 1999; 7 cases had a history of hyperbilirubinemia in the neonatal period and 2 of them were diagnosed of sensorineural hearing loss. We discuss how the bilirubin or any other associated factor might have been the cause and this could explain the selective affectation of some children.

    Full Text Available Studies on the impact of Eucalyptus spp. on Brazilian soils have focused on soil chemical properties and isolating interesting microbial organisms. Few studies have focused on microbial diversity and ecology in Brazil due to limited coverage of traditional cultivation and isolation methods. Molecular microbial ecology methods based on PCR amplified 16S rDNA have enriched the knowledge of soils microbial biodiversity. The objective of this work was to compare and estimate the bacterial diversity of sympatric communities within soils from two areas, a native forest (NFA and an eucalyptus arboretum (EAA. PCR primers, whose target soil metagenomic 16S rDNA were used to amplify soil DNA, were cloned using pGEM-T and sequenced to determine bacterial diversity. From the NFA soil 134 clones were analyzed, while 116 clones were analyzed from the EAA soil samples. The sequences were compared with those online at the GenBank. Phylogenetic analyses revealed differences between the soil types and high diversity in both communities. Soil from the Eucalyptus spp. arboretum was found to have a greater bacterial diversity than the soil investigated from the native forest area.Estudos sobre impacto do Eucalyptus spp. em solos brasileiros têm focalizado propriedades químicas do solo e isolamento de microrganismos de interesse.

    We sought to examine neonatal morbidity associated with different maneuvers used among term patients who experience a shoulder dystocia. We conducted a retrospective cohort study of all women who experienced a clinically diagnosed shoulder dystocia at term requiring obstetric maneuvers at a single tertiary care hospital from 2005 through 2008. We excluded women with major fetal anomaly, intrauterine death, multiple gestation, and preterm. Women exposed to Rubin maneuver, Wood's screw maneuver, or delivery of the posterior arm were compared to women delivered by McRoberts/suprapubic pressure only, which served as the reference group. The primary outcome was a composite morbidity of neonatal injury (defined as clavicular or humeral fracture or brachial plexus injury) and neonatal depression (defined as Apgar dystocia, defined as time from delivery of fetal head to delivery of shoulders. Among the 231 women who met inclusion criteria, 135 were delivered by McRoberts/suprapubic pressure alone (57.9%), 83 women were exposed to Rubin maneuver, 53 women were exposed to Wood's screw, and 36 women were exposed to delivery of posterior arm. Individual maneuvers were not associated with composite morbidity, neonatal injury, or neonatal depression after adjusting for nulliparity and duration of shoulder dystocia. We found no association between shoulder dystocia maneuvers and neonatal morbidity after adjusting for duration, a surrogate for severity. Our results demonstrate that clinicians should utilize the maneuver most likely to result in successful delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

    2016-08-01

    Full Text Available Background: Seizure is a common neurological disorder in neonatal age group!. Primary metabolic derangement is one of the important reason behind this convulsion during this period. Among primary metabolic derangement hypoglycemia, is most common followed by bypocalcaemia, hypomagnesaemia, low zinc status etc. As causes of many cases of convul­sion remain unknown in neonate. Objectives: To see the zinc status in the sera of neonate with convulsion. So that if needed early intervention can be taken up and thereby prevent complications. Method: A total of 50 neonates (1-28 days who had convulsion with no apparent reasons of convulsion were enrolled as cases and 50 healthy age and sex matched neonates were enrolled as controls. After a quick clinical evaluation serum zinc status was estimated from venous blood by atomic absorption method in Chemistry Division, Atomic Energy Centre. Low zinc was considered if serum value was <0.7mg/L. Results: Among a total of 50 cases 6% had low zinc value & 2% of controls also had low zinc level. The mean serwu zinc level of cases and controls were 1.57±0.95 and 2.37±1.06 mmol/1 respectively (p<0.01. Conclusion: From the study it is seen that low zinc value is an important cause of neonatal seizure due to primary metabolic abnormalities. So early recognition and treatment could save these babies from long term neurological sequelies.

Methods We performed a case-control study involving 100 neonates with and without hearing loss who were born at Sanglah Hospital, Denpasar from November 2012 to February 2013. Subjects were consisted of 2 groups, those with hearing loss (case group of 50 subjects and without hearing loss (control group of 50 subjects. The groups were matched for gender and birth weight. We assessed the following risk factors for hearing loss: severe neonatal asphyxia, hyperbilirubinemia, meningitis, history of aminoglycoside therapy, and mechanical ventilation by Chi-square analysis. The results were presented as odds ratio and its corresponding 95% confidence intervals. Results Seventy percent of neonates with hearing loss had history of aminoglycoside therapy. Multivariable analysis revealed that aminoglycoside therapy of 14 days or more was a significant risk factor for hearing loss (OR 2.7; 95%CI 1.1 to 6.8; P=0.040. There were no statistically significant associations between hearing loss and severe asphyxia, hyperbilirubinemia, meningitis, or mechanical ventilation. Conclusion Aminoglycoside therapy for >=14 days was identified as a risk factor for hearing loss in neonates.

    Several attempts have been made in the past few years to develop and implement an automated segmentation of neonatal brain structural MRI. However, accurate automated MRI segmentation remains challenging in this population because of the low signal-to-noise ratio, large partial volume effects and inter-individual anatomical variability of the neonatal brain. In this paper, we propose a learning method for segmenting the whole brain cortical grey matter on neonatal T2-weighted images. We trained our algorithm using a neonatal dataset composed of 3 fullterm and 4 preterm infants scanned at term equivalent age. Our segmentation pipeline combines the FAST algorithm from the FSL library software and a Bayesian segmentation approach to create a threshold matrix that minimizes the error of mislabeling brain tissue types. Our method shows promising results with our pilot training set. In both preterm and full-term neonates, automated Bayesian segmentation generates a smoother and more consistent parcellation compared to FAST, while successfully removing the subcortical structure and cleaning the edges of the cortical grey matter. This method show promising refinement of the FAST segmentation by considerably reducing manual input and editing required from the user, and further improving reliability and processing time of neonatal MR images. Further improvement will include a larger dataset of training images acquired from different manufacturers.

    Objective This study aimed to investigate the relationship between maternal hypertensive disease and other risk factors and the neonatal development of necrotizing enterocolitis (NEC). Methods This was a retrospective case control study of infants with NEC from 2008 to 2012. The primary exposure of interest was maternal hypertensive disease, which has been hypothesized to put infants at risk for NEC. Other variables collected included demographics, pregnancy complications, medications, and neonatal hospital course. Data was abstracted from medical records. Results 28 cases of singleton neonates with NEC and 81 matched controls were identified and analyzed. There was no significant difference in the primary outcome. Fetuses with an antenatal diagnosis of growth restriction were more likely to develop NEC (p=0.008). Infants with NEC had lower median birth weight than infants without NEC (p=0.009). Infants with NEC had more late-onset sepsis (p=0.01) and mortality before discharge (p=0.001). Conclusions The factors identified by this case-control study that increased the risk of neonatal NEC included intrauterine growth restriction and lower neonatal birth weight. The primary exposure, hypertensive disease, did not show a significantly increased risk of neonatal NEC, however there was a nearly two-fold difference observed. Our study was underpowered to detect the observed difference. PMID:25162307

The health team must consider multiple situations, where the neonate is at risk of having an adverse effect. One of the main interventions that health professionals must practice when interacting with hospitalized newborns is skin care. Neonates often suffer from diaper rash or intravenous drugs extravasation. Recently, hospitalized neonates and especially those in an unstable clinical situation are also at a risk of developing pressure ulcers. The presence of a pressure ulcer in a neonate can lead to serious problems to survival (eg, sepsis, clinical instability. This is the reason why, with this literature review, we attempt to answer questions from health professionals caring for neonates about the prevention and treatment of pressure ulcers.

    Full Text Available INTRODUCTION Acute renal failure (ARF is a frequent clinical condition in neonatal intensive care units (NICU. The leading cause of neonatal ARF is perinatal asphyxia (PS. The aim of this study was to examine the relationship between the degree of PS and the severity of ARF in term neonates. METHODS A prospective survey of 31 term neonates with Ps and but without congenital malformations or sepsis was performed in NICU of the regional Hospital of Gynaecology and Obstetrics in Belgrade (average number of deliveries about 6000 per year. ARF was diagnosed in the first 7 days of life when plasma creatinine was above 133 μmοΙ/L for at least 48 hours while maternal renal function was normal. The degree of PS was determined according to Apgar score (AS at 1 min. The severe PS was defined as AS < 3 and moderate PS as AS 4-6. RESULTS Twenty neonates (64% had oliguric ARF with urine output of 0.37 ±0.16 ml/kg/h while the others had nonoliguric ARF with urine output of 2.4 ± 0.7 ml/kg/h. Most of neonates with oliguric ARF (65% had severe perinatal asphuxia while in those with nonoliguric ARF moderate perinatal asphyxia predominated (73%. DISCUSSION During hypoxic-ischaemic events many organs are injured, and the most vulnerable ones are kidneys and central nervous system. Our results showed a strong connection between perinatal asphyxia and A, which was in accordance with the results of other studies. Neonates with severe perinatal asphyxia had serious impairment of renal function, which was confirmed with strong correlation between Apgar score and plasma creatinine. In neonates with oliguric ARF, but not in those with nonoliguric ARF, the highly positive linear correlations were found between AS and urinary output (r = 0.77; p < 0.01, plasma creatinine (r = 0.78; p < 0.01, fractional excretion of sodium (r = 0.76; p < 0.01, and index of renal failure (r = 0.80; p < 0.01.

    Neonates born to opioid-maintained mothers are at risk of developing neonatal abstinence syndrome (NAS), which often requires pharmacological treatment. This study examined the effect of opioid maintenance treatment on the incidence and timing of NAS, and compared two different NAS treatments (phenobarbital versus morphine hydrochloride). Fifty-three neonates born to opioid-maintained mothers were included in this study. The mothers received methadone (n=22), slow-release oral morphine (n=17) or buprenorphine (n=14) throughout pregnancy. Irrespective of maintenance treatment, all neonates showed APGAR scores comparable to infants of non-opioid dependent mothers. No difference was found between the three maintenance groups regarding neonatal weight, length or head circumference. Sixty percent (n=32) of neonates required treatment for NAS [68% in the methadone-maintained group (n=15), 82% in the morphine-maintained group (n=14), and 21% in the buprenorphine-maintained group (n=3)]. The mean duration from birth to requirement of NAS treatment was 33 h for the morphine-maintained group, 34 h for the buprenorphine-maintained group and 58 h for the methadone-maintained group. In neonates requiring NAS treatment, those receiving morphine required a significantly shorter mean duration of treatment (9.9 days) versus those treated with phenobarbital (17.7 days). Results suggest that morphine hydrochloride is preferable for neonates suffering NAS due to opioid withdrawal.

Este trabalho teve como objetivo o estudo do perfil da resistência aos desinfetantes das bactérias lançadas na rede de esgoto pelo efluente hospitalar. Na caracterização microbiológica do efluente do Hospital de Clínicas Buenos Aires, determinou-se a concentração de bactérias heterotróficas, bactérias indicadoras fecais, Pseudomonas sp. e Staphylococcus sp. presentes. A resistência aos desinfetantes empregados no hospital, glutaraldeído, iodo povidona, e clorexidina foi então avaliada. Verificou-se a existência de bactérias resistentes à clorexidina em número variando de 10³ a 10(6 bactérias/100 mL e de bactérias resistentes a outros desinfetantes em uma faixa de variação de 10³ a 10(4 bactérias/100 mL. Bactérias dos gêneros Staphylococcus e Bacillus, e da família Enterobacteriaceae, envolvidas em infecções hospitalares, apresentaram resistência aos desinfetantes testados. Estes resultados indicam que as águas residuárias de hospitais desempenham um papel de grande relevância na disseminação de linhagens bacterianas resistentes aos desinfetantes no meio aquático.

There was an 88.5% (23 of 26) response rate to this survey. 6 (26%) units had a written policy, and 16 (70%) had an unwritten agreed practice. In the Vermont Oxford Network\\'s potentially better practices daily weight measurements on newborn infants are recommended until the infant is stable and growing and then alternate day measurements The most common practices in this survey were to weigh infants on alternate days, this occurred in 9 (39%) units, and twice weekly in 6 (26%). Less than 31% of units had a separate policy for those less than 30 weeks, on assisted ventilation, or transitioning to enteral feeds. Most weigh infants on alternate days, and plot weights weekly, which is in keeping with best practice. Few units have separate policies for specific subgroups as is recommended in the limited literature. Consensus guidelines should be developed and promoted nationally.

    The pediatric dental approach to the oral cavity of newborns requires special attention, as many aspects are unique and peculiar to this period of life. It is important that pediatricians and pediatric dentists be aware of the characteristics within normal newborn patterns and prepared to make a correct diagnosis of abnormalities at early stages. Congenital eruption cysts (ECs) are rarely observed in newborns, as at this stage of a child's life, tooth eruption is unusual. This study reports a case of EC treated successfully by monitoring of the lesion, without any surgical procedure. In the 4th month, the lesion had completely regressed, and the deciduous central incisors had erupted without problems. The clinical and radiographic monitoring of ECs in newborns seems to be a satisfactory management procedure, similar to what is recommended for older children.

    Neonates in the-Neonatal Intensive Care Unit (NICU) can receive large numbers of radiographs owing to the clinical conditions they may present. More neonatal radiation dosimetry data are required for three fundamental reasons: (1.) to aid in the establishment of reference dose levels for interinstitutional comparisons; (2.) to improve childhood cancer risk estimates following neonatal exposure; and (3.) to indicate appropriate directions for dose reduction. This paper describes an investigation of two different NICU radiological techniques with significantly different neonate doses. While patient-matched images taken with both techniques were assessed in a blind review, this component of the study is beyond the scope of this paper and is not discussed here. (author)

    Full Text Available São relatados três casos de conjuntivite bacteriana associada à doença dentária grave em chinchilas. Todas as chinchilas afetadas tinham histórico de emagrecimento, hipersalivação e epífora, que progrediu para exsudação ocular purulenta. Durante a necropsia, foi constatado marcado alongamento da coroa clínica dos incisivos e molares, e crescimento do ápice dentário, causando deformação óssea e compressão do canal lacrimal. Histologicamente, observou-se infiltrado de neutrófilos na conjuntiva e pálpebras. Cultivo microbiológico do exsudato ocular revelou crescimento de Staphylococcus coagulase-positiva . Uma compressão do canal lacrimal pelo crescimento dentário excessivo impediu a drenagem das lágrimas, resultando em epífora. Esse é um importante fator predisponente para infecção bacteriana ocular em chinchilas.Three cases of bacterial conjunctivitis associated with severe dental disease in chinchillas are described. All affected chinchillas had a history of weight loss, ptyalism, and epiphora which progressed to suppurative ocular exsudation. At necropsy incisor and molar teeth revealed marked elongation of the clinical crown and overgrowth of the dental apexes resulting in deformation of the tear ducts. Histologically, there was neutrophilic infiltrate in the conjunctiva and eyelid skin. Microbiological culture carried out in samples from the ocular exsudate yielded Staphylococcus coagulase-positive. Compression of the lacrimal duct by dental overgrowth compromised tear draining and resulting in epiphora. This is a major predisposing factor inducing bacterial ocular infection in chinchillas.

    Full Text Available Sarah M Desoky,1 Ranjit I Kylat,2 Unni Udayasankar,1 Dorothy Gilbertson-Dahdal1 1Department of Medical Imaging, University of Arizona College of Medicine, Tucson, AZ, USA; 2Division of Neonatal-Perinatal Medicine, Department of Pediatrics, University of Arizona College of Medicine, Tucson, AZ, USA Abstract: Neonatal intestinal obstruction is a common surgical emergency and occurs in approximately 1 in 2,000 live births. The causes of obstruction are diverse with varied embryological origins, and some underlying etiologies are not yet well described. Some findings of neonatal bowel obstruction can be detected prenatally on ultrasound imaging. The obstruction is classified as “high” when the level of obstruction is proximal to the ileum, and “low” when the level of obstruction is at the ileum or colon. Early diagnosis of the type of intestinal obstruction and localization of the obstructive bowel segment guides timely and appropriate management of the underlying pathologic entity. Neonatal bowel obstructions are ideally managed at specialized centers with a large volume of neonatal surgery and dedicated pediatric surgical and anesthesia expertise. Although surgical intervention is necessary in most cases, initial management strategies often target underlying metabolic, cardiac, or respiratory abnormalities. Imaging plays a key role in early and accurate diagnosis of the abnormalities. When bowel obstruction is suspected clinically, initial imaging workup usually involves abdominal radiography, which may direct further evaluation with fluoroscopic examination such as upper gastrointestinal (UGI contrast study or contrast enema. This article provides a comprehensive review of clinical and radiological features of common and less common causes of intestinal obstruction in the neonatal age group, including esophageal atresia, enteric duplication cysts, gastric volvulus, congenital microgastria, hypertrophic pyloric stenosis, duodenal atresia

    Full Text Available Abstract Background Young maternal age has long been associated with higher infant mortality rates, but the role of socioeconomic factors in this association has been controversial. We sought to investigate the relationships between infant mortality (distinguishing neonatal from post-neonatal deaths, socioeconomic status and maternal age in a large, retrospective cohort study. Methods We conducted a population-based cohort study using linked birth-death certificate data for Missouri residents during 1997–1999. Infant mortality rates for all singleton births to adolescent women (12–17 years, n = 10,131; 18–19 years, n = 18,954 were compared to those for older women (20–35 years, n = 28,899. Logistic regression was used to estimate adjusted odds ratios (OR and 95% confidence intervals (CI for all potential associations. Results The risk of infant (OR 1.95, CI 1.54–2.48, neonatal (1.69, 1.24–2.31 and post-neonatal mortality (2.47, 1.70–3.59 were significantly higher for younger adolescent (12–17 years than older (20–34 years mothers. After adjusting for race, marital status, age-appropriate education level, parity, smoking status, prenatal care utilization, and poverty status (indicated by participation in WIC, food stamps or Medicaid, the risk of post-neonatal mortality (1.73, 1.14–2.64 but not neonatal mortality (1.43, 0.98–2.08 remained significant for younger adolescent mothers. There were no differences in neonatal or post-neonatal mortality risks for older adolescent (18–19 years mothers. Conclusion Socioeconomic factors may largely explain the increased neonatal mortality risk among younger adolescent mothers but not the increase in post-neonatal mortality risk.

    To test the discriminatory topographic potential of a new method of the automatic EEG analysis in neonates. A quantitative description of the neonatal EEG can contribute to the objective assessment of the functional state of the brain, and may improve the precision of diagnosing cerebral dysfunctions manifested by 'disorganization', 'dysrhythmia' or 'dysmaturity'. 21 healthy, full-term newborns were examined polygraphically during sleep (EEG-8 referential derivations, respiration, ECG, EOG, EMG). From each EEG record, two 5-min samples (one from the middle of quiet sleep, the other from the middle of active sleep) were subject to subsequent automatic analysis and were described by 13 variables: spectral features and features describing shape and variability of the signal. The data from individual infants were averaged and the number of variables was reduced by factor analysis. All factors identified by factor analysis were statistically significantly influenced by the location of derivation. A large number of statistically significant differences were also established when comparing the effects of individual derivations on each of the 13 measured variables. Both spectral features and features describing shape and variability of the signal are largely accountable for the topographic differentiation of the neonatal EEG. The presented method of the automatic EEG analysis is capable to assess the topographic characteristics of the neonatal EEG, and it is adequately sensitive and describes the neonatal electroencephalogram with sufficient precision. The discriminatory capability of the used method represents a promise for their application in the clinical practice.

    To assess development of fatigue during chest compressions (CCs) in simulated neonatal cardiopulmonary resuscitation (CPR). Prospective randomized manikin crossover study. Thirty neonatal healthcare professionals who successfully completed the Neonatal Resuscitation Program performed CPR using (i) 3:1 compression:ventilation (C:V) ratio, (ii) continuous CC with asynchronous ventilation (CCaV) at a rate of 90 CC per min and (iii) CCaV at 120 CC per min for a duration of 10 min on a neonatal manikin. Changes in peak pressure (a surrogate of fatigue) and CC rate were continuously recorded and fatigue among groups was compared. Participants were blinded to pressure tracings and asked to rate their level of comfort and fatigue for each CPR trial. Compared with baseline, a significant decrease in peak pressure was observed after 72, 96 and 156 s in group CCaV-120, CCaV-90 and 3:1 C:V, respectively. CC depth decreased by 50% within the first 3 min during CCaV-120, 30% during CCaV-90 and 20% during 3:1 C:V. Moreover, 3:1 C:V and CCaV were similarly preferred by healthcare professionals. Similarly, 3:1 C:V and CCaV CPR were also fatiguing. We recommend that rescuers should switch after every second cycle of heart rate assessment during neonatal CPR.

    Asymmetry of the neonatal brain is not yet understood at the level of structural connectivity. We utilized DTI deterministic tractography and structural network analysis based on graph theory to determine the pattern of structural connectivity asymmetry in 124 normal neonates. We tracted white matter axonal pathways characterizing interregional connections among brain regions and inferred asymmetry in left and right anatomical network properties. Our findings revealed that in neonates, small-world characteristics were exhibited, but did not differ between the two hemispheres, suggesting that neighboring brain regions connect tightly with each other, and that one region is only a few paths away from any other region within each hemisphere. Moreover, the neonatal brain showed greater structural efficiency in the left hemisphere than that in the right. In neonates, brain regions involved in motor, language, and memory functions play crucial roles in efficient communication in the left hemisphere, while brain regions involved in emotional processes play crucial roles in efficient communication in the right hemisphere. These findings suggest that even at birth, the topology of each cerebral hemisphere is organized in an efficient and compact manner that maps onto asymmetric functional specializations seen in adults, implying lateralized brain functions in infancy.

    To determine practice patterns of office-based pediatricians and neonatologists in the treatment of neonatal hyperbilirubinemia in healthy, term newborns during 1992, before the publication of the practice guideline for treatment of neonatal jaundice by the American Academy of Pediatrics (AAP). The survey was undertaken to inform the AAP's Subcommittee on Hyperbilirubinemia on current practices and to aid it in its preparation of the guidelines. It was also anticipated that this survey would serve as a basis for comparison for a second survey to be performed several years after the publication of the practice guidelines. A self-administered questionnaire describing a single case of a jaundiced, breastfed 36-hour-old healthy, full-term infant with a total serum bilirubin concentration of 11.0 mg/dL (188 microM/L) was sent to a random sample of 600 office-based pediatricians and 606 neonatologists who were members of the AAP. The final response rate was 74%. Respondents were asked to answer questions regarding treatment of the case based on their actual practices. Ranges of total serum bilirubin concentration were provided as possible answers to questions on initiation of phototherapy and exchange transfusion, and interruption of breastfeeding. Respondents were also queried about frequency of serum bilirubin testing, locations of phototherapy administration, and factors influencing their therapeutic decisions. Four hundred forty-two office-based pediatricians and 444 neonatologists completed the survey. There was a tendency for neonatologists to initiate both phototherapy and exchange transfusions at lower serum bilirubin concentrations than office-based general pediatricians. At a serum bilirubin of 13 to 19 mg/dL (222 to 325 microM/L), 54% of office-based pediatricians stated they would initiate phototherapy whereas 76% of neonatologists would do so. Forty percent of office-based practitioners said they would perform exchange transfusions at serum bilirubin levels

    Full Text Available The objective of this study is to determine risk factors causing increase in very low birth way (VLBW neonatal mortality. The medical files of all neonates weighing ≤1500 g, born in Vali-e-Asr hospital (2001-2004 were studied. Two groups of neonates (living and dead were compared up to the time of hospital discharge or death. A total of 317 neonates were enrolled. A meaningful relationship existed between occurrence of death and low gestational age (P=0.02, low birth weight, lower than 1000 g (P=0.001, Apgar score <6 at 5th minutes (P=0.001, resuscitation at birth (P=0.001, respiratory distress syndrome (P=0.001 need for mechanical ventilation (P=0.001, neurological complications (P=0.001 and intraventricular hemorrhage (P=0.001. Regression analysis indicated that each 250 g weight increase up to 1250 g had protective effect, and reduced mortality rate. The causes of death of those neonates weighting over 1250 g should be sought in factors other than weight. Survival rate was calculated to be 80.4% for neonates weighing more than 1000 g. The most important high risk factors affecting mortality of neonates are: low birth weight, need for resuscitation at birth, need for ventilator use and intraventricular hemorrhage.

    Full Text Available Background: Neonatal survival is one of the most important challenges today. Over 99% of neonatal mortalities occur in the developing countries, and epidemiologic studies emphasize on this issue in the developed countries, as well. In this study, we attempted to investigate the causes of neonatal mortality in Taleghani Hospital, Tabriz, Iran.Methods: In this cross-sectional study, we studied causes of neonatal mortality in neonatal intensive care unit (NICU of Taleghani Hospital, Tabriz, Iran, during 2013-2014. Data collection was performed by the head nurse and treating physician using a pre-designed questionnaire. Most of the data were extracted from the neonatal records. Information regarding maternal underlying diseases and health care during pregnancy was extracted from mothers' records.Results: A total of 891 neonates were admitted to NICU of Taleghani Hospital of Tabriz, Iran, during 2013-2014, 68 (7.5% of whom died. Among these cases, 37 (%54.4 were male, 29 (29.4% were extremely low birth weight, and 16 (23.5% weighed more than 2.5 kg. The main causes of mortality were congenital anomalies (35.3%, prematurity (26.5%, and sepsis (10.3%, respectively.Conclusion: Congenital anomaly is the most common cause of mortality, and the pattern of death is changing from preventable diseases to unavoidable mortalities

  9. Endocardial Pacemaker Implantation in Neonates and Infants

    Full Text Available Transvenous pacemaker lead implantation is the preferred method of pacing in adult patients. Lead performance and longevity are superior and the implantation approach can be performed under local anaesthetic with a very low morbidity. In children, and especially in neonates and infants, the epicardial route was traditionally chosen until the advent of smaller generators and lead implantation techniques that allowed growth of the child without lead displacement. Endocardial implantation is not universally accepted, however, as there is an incidence of venous occlusion of the smaller veins of neonates and infants with concerns for loss of venous access in the future. Growing experience with lower profile leads, however, reveals that endocardial pacing too can be performed with low morbidity and good long-term results in neonates and infants.

    The onset of Graves disease during pregnancy exposes the neonate to the risk of hyperthyroidism. The newborn must be monitored and treatment modalities known to ensure early treatment of the newborn. We report on the case of an infant born at term of a mother with Graves disease discovered during pregnancy. He was asymptomatic during the first days of life, before declaring the disease. Neonatal hyperthyroidism was confirmed by hormonal assays. Hyperthyroidism was treated with antithyroid drugs and propranolol with a satisfactory clinical and biological course. Neonatal hyperthyroidism should be systematically sought in infants born to a mother with Graves disease. The absence of clinical signs during the first days of life does not exclude the diagnosis. The duration of monitoring should be decided according to the results of the first hormonal balance tests. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Neonatal Graves' disease presenting as conjugated hyperbilirubinemia is a diagnostic challenge because the differential includes a gamut of liver and systemic diseases. We present a unique case of neonatal Graves' disease in a premature infant with conjugated hyperbilirubinemia born to a mother with hypothyroidism during pregnancy and remote history of Graves' disease. Infant was treated with a combination of methimazole, propranolol, and potassium iodide for 4 weeks. Thyroid function improved after 8 weeks of treatment with full recovery of thyroid function, disappearance of thyroid-stimulating antibodies, and resolution of failure to thrive and conjugated hyperbilirubinemia. This case provides several clinical vignettes as it is a rare, severe, presentation of an uncommon neonatal disease, signs, symptoms, and clinical history presented a diagnostic challenge for neonatologists and endocrinologists, normal newborn screen was misleading, and yet timely treatment led to a full recovery.

    Birth season has been reported to be a risk factor for several immune-mediated diseases. We hypothesized that this association is mediated by differential changes in neonatal immune phenotype and function with birth season. We sought to investigate the influence of season of birth on cord blood...... immune cell subsets and inflammatory mediators in neonatal airways. Cord blood was phenotyped for 26 different immune cell subsets, and at 1 month of age, 20 cytokines and chemokines were quantified in airway mucosal lining fluid. Multivariate partial least squares discriminant analyses were applied...... to determine whether certain immune profiles dominate by birth season, and correlations between individual cord blood immune cells and early airway immune mediators were defined. We found a birth season-related fluctuation in neonatal immune cell subsets and in early-life airway mucosal immune function...

    This study aims at determining the prevalence of neonatal hypoglycemia and its underlying causes. In this prospective study 14168 newborns delivered in Tabriz Alzahra Hospital during 2 years were evaluated in regard to blood glucose level at first 24 h of life. Glucose oxidase method with 4-aminophenazone with a Greiner G-300 was the used method for determining the blood glucose level. Cases with blood glucose causes of this condition, as well as the short-term mortality rate were determined. Prevalence of neonatal hypoglycemia was 0.4% (52 newborns). Underlying causes of hypoglycemia were prematurity (61.5%), diabetic mother (13.6%), septicemia (9.6%), perinatal asphyxia (9.6%), stress (3.8%) and neonatal hyperinsulinism (1.9%). The mortality rate was 53.8%, with prematurity as the leading cause of death.

  15. The Neurodevelopmental Impact of Neonatal Morphine Administration

    Directory of Open Access Journals (Sweden)

    Stephanie Attarian

    2014-04-01

    Full Text Available Medical management of newborn infants often necessitates recurrent painful procedures, which may alter nociceptive pathways during a critical developmental period and adversely effect neuropsychological outcomes. To mitigate the effects of repeated painful stimuli, opioid administration for peri-procedural analgesia and ICU (intensive care unit sedation is common in the NICU (neonatal intensive care unit. A growing body of basic and animal evidence suggests potential long-term harm associated with neonatal opioid therapy. Morphine increases apoptosis in human microglial cells, and animal studies demonstrate long-term changes in behavior, brain function, and spatial recognition memory following morphine exposure. This comprehensive review examines existing preclinical and clinical evidence on the long-term impacts of neonatal pain and opioid therapy.

    Neonatal adrenal hematoma is a rare condition, most frequently caused by trauma. We report three cases of adrenal hematoma admitted to the Neonatology and Neonatal Intensive Care Unit in the A. Harouchi Children's Hospital, the Ibn Rushd University Hospital in Casablanca, Morocco, over a 2-year period from January 2011 to December 2012. The average age of these patients was 5 days. The clinical presentations were diverse; the most common manifestations were intense jaundice in one case, acute adrenal insufficiency in one case, and severe anemia in the other case. Abdominal ultrasonography was used to confirm the diagnosis and monitor adrenal hemorrhage in all the patients. Analysis of clinical, laboratory, and ultrasonography data showed a favorable prognosis in all the patients. Based on these observations, we discuss the risk factors, clinical presentations, progression and management of neonatal adrenal hemorrhage. Copyright © 2014. Published by Elsevier SAS.

    2018-03-01

    Extracorporeal membrane oxygenation (ECMO), a life-saving therapy for respiratory and cardiac failure, was first used in neonates in the 1970s. The indications and criteria for ECMO have changed over the years, but it continues to be an important option for those who have failed other medical therapies. Since the Extracorporeal Life Support Organization (ELSO) Registry was established in 1989, more than 29,900 neonates have been placed on ECMO for respiratory failure, with 84% surviving their ECMO course, and 73% surviving to discharge or transfer. In this chapter, we will review the basics of ECMO, patient characteristics and criteria, patient management, ECMO complications, special uses of neonatal ECMO, and patient outcomes.

    1991-01-01

    The Authors report their experience in the employment of a computerized digital radiographic system in Neonatal Intensive Care. The analog screen-film system is replaced by photosensitive imaging plates, scanned after X-ray exposure by a laser that releases the digital image, which can then be manipulated on computer work-stations. In a period of twelve months about 200 chest-abdomen X-ray examinations in Neonatal Intensive Care have been performed using this method with good technical and diagnostic results. The use of digital radiography in the neonatal area is of high interest: this system produces good quality images, there is a reduction in radiation dose and 'retakes', the system allows selective enhancement of different structures and their magnification.

    The adrenal hemorrhage is a relatively rare event in newborns but must be considered in the presence of a persistent unexplained jaundice, especially in presence of predisposing factors. Serial ultrasonography is the modality of choice for initial diagnosis and follow-up of neonatal adrenal hemorrhage. We report two cases of neonatal adrenal hemorrhage presenting with persistent jaundice. The causes of the neonatal adrenal hemorrhages were a difficult vaginal delivery in macrosomic infant and a neonatal infection.

    Neonatal suppurative parotitis is very rare. One review of the English-language literature spanning 35 years found only 32 cases. Most cases are managed conservatively with antibiotic therapy; early antibiotic treatment reduces the need for surgery. The predominant organism is Staphylococcus aureus. We report a new case of neonatal suppurative parotitis in a 3-week-old boy. The patient was diagnosed on the basis of parotid swelling, a purulent exudate from a Stensen duct, and the growth of pathogenic bacteria in culture. He responded well to 9 days of intravenous antibiotic therapy. We also discuss the microbiologic and clinical patterns of this disease.

In neonates the common causes of secondary hypertension were renal vascular thrombosis (33%), polycystic kidney disease (25%), and obstructive uropathy (17%). US and renal scans were the most useful studies and yielded diagnostic information in approximately 70% of cases. Surgically correctable hypertension was found in almost half the patients. In patients over 1 year of age, the common causes of hypertension were medical renal disease (50%) and renovascular hypetension (15%). Urography, scintigraphy, and arteriography played a crucial role in their evaluation

    Listeria monocytogenes was isolated in two neonates born consecutively in the same hospital in France. The isolates had indistinguishable pulsed-field electrophoresis profiles. Retrospective epidemiological investigations found no evidence of a food-borne or environmental source. Infection control protocols and decontamination processes were in accordance with standard recommendations. The timing of onset of these infections within the same maternity unit, and the similarity of pulsed-field gel electrophoresis profiles suggests cross-infection of L. monocytogenes between the two neonates.

    Neonatal onset multisystem inflammatory disease is a rare disorder first described by Lorber in 1973. An additional 29 cases have been recorded. Two patients are described here, one with a 17 year follow-up. The typical features are a rash, fever, adenopathy, hepatosplenomegaly, and a severe, deforming arthropathy predominantly affecting large joints. The most striking feature is the onset in the neonatal period. Other associated features include inflammation, chronic meningitis, anemia, and persistent leukocytosis. Most, if not all, patients develop bizarre epiphyseal radiographic findings that are virtually pathognomonic. This disease is distinct from Still disease. (orig.).

    Neonatal Marfan syndrome is a rare and severe phenotype of this disease. A poor prognosis is anticipated due to the high probability of congestive heart failure, and mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management at an early age. We present two consecutive patients with this disease who are the first reported cases from Iran to the best of our knowledge. Unfortunately both of them died shortly after diagnosis. Neonatal Marfan syndrome is reported from Iran and has a poor prognosis like the patients reported from elsewhere.

    Neonatal encephalopathy (NE) is a major contributor to neurodevelopmental deficits including cerebral palsy in term and near-term infants. The long-term neurodevelopmental outcome is difficult to predict with certainty in first few days of life. Multiorgan involvement is common but not part of the diagnostic criteria for NE. The most frequently involved organs are the heart, liver, kidneys and hematological system. Cerebral and organ involvement is associated with the release of organ specific biomarkers in cerebrospinal fluid, urine and blood. These biomarkers may have a role in the assessment of the severity of asphyxia and long-term outcome in neonates with NE.

    An otherwise healthy, full-term neonate presented at day 15 of life to the pediatric emergency with generalized papulo-pustular rash for 2 d. This was finally diagnosed as bullous impetigo caused by Staphylococcus aureus (S. aureus). The skin lesions decreased significantly after starting antibiotic therapy and drainage of blister fluid. There was no recurrence of the lesions on follow-up. This case of generalized pustular eruption due to S. aureus in a neonate is reported, as it poses a diagnostic dilemma and can have serious consequences if left untreated.

  10. Is neonatal group B streptococcal infection preventable?

    Early onset group B streptococcal (EOGBS) infection causes significant neonatal morbidity and mortality. We determined the incidence of EOGBS at Galway University Hospital (GUH) and examined any "missed opportunities" for preventing neonatal infection between 2004 and 2009. Our obstetric approach is risk-based. The incidence was 0.45\\/1,000 live-births; one death and one with neurological sequelae. A single mother received IAP; however we could not determine any potential for reducing cases of EOGBS by improving current IAP usage.

    US is a noninvasive modality that has proved highly valuable in the assessment of congenital intracranial anomalies in the neonate. The patterns of malformation must be familiar to those who obtain and interpret neonatal cranial sonograms. The authors present a variety of cases of congenital anomalies studied with US, including agenesis of the corpus callosum, Dandy-Walker malformation, occipital enecphalocele, congenital hydrocephalus, vein of Galen aneurysm, hydranencephaly, holoprosencephaly, absence of the septum pellucidum, schizencephaly, and hypoplastic cerebellum. Correlation with other radiographic modalities and pathologic follow-up, available in a majority of cases, is included

    Emerging data suggest intraventricular hemorrhage (IVH) of the preterm neonate is a complex disorder with contributions from both the environment and the genome. Environmental analyses suggest factors mediating both cerebral blood flow and angiogenesis contribute to IVH, while candidate gene studies report variants in angiogenesis, inflammation, and vascular pathways. Gene-by-environment interactions demonstrate the interaction between the environment and the genome, and a non-replicated genome-wide association study suggests that both environmental and genetic factors contribute to the risk for severe IVH in very low-birth weight preterm neonates.

    Water immersion in neonatal bereavement photography is a new technique intended to enhance the quality of the photographs provided to families following their loss. Water immersion appears to be most helpful following a second trimester fetal demise. This technique can be used by nurses, professional photographers and others in addition to more traditional neonatal bereavement photography. It does not require special skills or equipment and can be implemented in virtually any perinatal setting. The enhanced quality of photographs produced with this method can potentially provide a source of comfort to grieving families. © 2014 AWHONN.

    Neonatal immune hyperthyroidism is a rare but potentially fatal condition. It occurs in 1-5% of infants born to women with Graves' disease (GD). In most of the cases it is due to maternal antibodies transferred from the mother into the fetal compartment, stimulating the fetal thyroid by binding thyrotropin (thyroid-stimulating hormone, TSH) receptor. We present a case of neonatal thyrotoxicosis due to maternal GD detected at 25 days of age and discuss the potential pitfalls in the diagnosis. 2015 BMJ Publishing Group Ltd.

    Neonatal hyperthyroidism is a rare condition caused either by transplacental passage of thyroid-stimulating immunoglobulins from a mother with Graves’ disease or by activating mutations of the thyrotropin receptors and α-subunit of G-protein. The clinical features may vary. We report a case of neonatal thyrotoxicosis in an infant born to a mother with Graves’ disease, who presented with cardiorespiratory failure and persistent pulmonary hypertension (PPHN). PPHN resolved with specific antithyroid treatment and extracorporeal membrane oxygenation was not required. PMID:22669869

    Full Text Available We present a case of neonatal chlamydial pneumonitis to illustrate that a high index of suspicion is necessary to make the diagnosis so that treatment can be promptly instituted. The child was afebrile and the only symptom was a cough. The respiratory equations are calculated to understand the respiratory physiology. There was no overt abnormality with ventilation, oxygenation, compliance, resistance, or ventilation-perfusion mismatch despite radiographic abnormality. The literature is searched to review if treatment with a systemic macrolide antibiotic is needed in an otherwise asymptomatic neonate with chlamydial pneumonitis.

    Full Text Available Com o objetivo de avaliar produtos químicos no controle da mancha-bacteriana em tomate para processamento industrial, foram conduzidos dois ensaios na área experimental da Unilever Bestfoods, em Goiânia-GO. No primeiro, o híbrido Heinz 9992 foi inoculado com Xanthomonas perforans em blocos casualizados, com 15 tratamentos e três repetições. O segundo ensaio foi em blocos ao acaso com parcelas subdivididas com três repetições. A parcela principal foi "tratamento químico" (10 tratamentos e a subparcela "híbrido" (Hypeel 108 e U2006. Inoculou-se X. perforans e X. gardneri. Em ambos os ensaios os produtos testados, em diferentes números de aplicações e regimes, foram: acibenzolar-S-metil (ASM; famoxadona + mancozebe; metiram + piraclostrobina; fosfito PK; cloretos de benzalcônio; óxido cuproso e hidróxido de cobre (SC, WP e WG. Em ambos os ensaios, foram avaliados severidade da doença nas folhas, número de frutos com sintomas e produtividade. No segundo ensaio avaliou-se também o número de frutos com escaldadura. No primeiro ensaio foram detectadas diferenças significativas (p>0,05 entre os tratamentos somente nas duas primeiras avaliações de severidade, mas nenhum dos tratamentos diferiu da testemunha. No segundo ensaio, para severidade foliar, foi detectada diferença significativa apenas para os híbridos na primeira avaliação. Para número de frutos com sintomas e escaldadura a interação entre os fatores "tratamento químico" e "híbrido" foi também significativa. Nas folhas, 'U2006' foi mais resistente do que 'Hypeel 108', que apresentou maior incidência de escaldadura, mas nos frutos ocorreu o inverso. Para produtividade, os dois fatores foram significativos. 'U2006' foi mais produtivo do que 'Hypeel 108'. Entre os 10 tratamentos químicos, apesar de nenhum ter diferido da testemunha, famoxadona + mancozebe, que resultou em maior produtividade, diferiu de hidróxido de cobre (WG, ASM - famoxadona + mancozebe e

    Full Text Available OBJECTIVE: To assess professional nurses', associate degree prepared nurses', licensed practical nurses', and nursing assistants' knowledge of the causes of multi-resistant bacterial infections, the risks theses infections pose to health care providers, the chain of transmission of these infections, and patients' susceptibility to colonization of these multi-resistant bacterial infections. METHODS: This descriptive study was conducted in a major general hospital in Minas Gerais, Brazil. The sample consisted of 42 nursing staff from a medical clinical unit. Descriptive statistics were used to analyze and present the data. RESULTS: Nursing staff had unsatisfactory knowledge of the causes of multi-resistant bacterial infections, the chain of transmission of multi-resistant bacterial infections, and patients' susceptibility to colonization of multi-resistant bacterial infections. However, the majority of participants had some knowledge about the risks that multi-resistant bacterial infections posed to health care providers. CONCLUSION: Lack of knowledge among nursing staff compromise adherence to preventive measures and nursing management of multi-resistant bacterial infections.OBJETIVO: Evaluar el conocimiento de los enfermeros, técnicos y auxiliares de enfermería de un hospital general de Minas Gerais, en cuanto a las causas da multirresistencia bacteriana, los riesgos para el equipo de salud, el modo de transmisión y susceptibilidad de los pacientes a la colonización por bacterias resistentes a múltiples drogas. MÉTODOS: Realizado en la clínica médica, fueron entrevistados 42 profesionales de enfermería encontrados en la unidad. En este estudio de tipo cuantitativo se realizó un análisis descriptivo de sus datos, utilizándose la estadística descriptiva con base en el cálculo de porcentaje, los cuales fueron presentados en tablas.

    Full Text Available The aim of this study was to characterize the treatments applied to newborns with congenital malformation hospitalized in a neonatal unit and to identify whether there is an association among the treatments used and the type of malformation. A descriptive, prospective and quantitative study was developed in a public institution in Fortaleza, Ceará, Brazil. Data were collected using the medical records of 30 neonates with congenital malformations. The incidence of malformations was higher among females, regardless of the mother’s age, gestational age or weight at birth; malformations of the central nervous and musculoskeletal systems prevailed. The treatments used varied according to the clinical evolution of the neonate. The data collected did not present statistical significance when associated with the variable of congenital malformation and the treatments used (p>0.05. The treatments are not directly related to the type of malformation, but to the clinical condition of the neonate.

  20. Neonatal Bartter Syndrome in association with congenital adrenal hyperplasia in a neonate - a rare combination.

    Neonatal Bartter syndrome (NBS) is an autosomal recessive renal tubulopathy characterized by hypokalaemic, hypochloraemic metabolic alkalosis associated with increased urinary loss of sodium, potassium, calcium and chloride. There is hyperreninaemia and hyperaldosteronaemia but normotension. Congenital adrenal hyperplasia (CAH), another autosomal recessive condition, may present in the neonatal period with vomiting, hypovolaemia, failure to gain weight or ambiguous genitalia. We report a case of NBS and CAH combination in a neonate. A male neonate born at term was admitted with history of recurrent vomiting and dehydration episodes. Investigations revealed electrolytes imbalance, metabolic alkalosis, raised aldosterone and renin levels suggestive of NBS. He was treated successfully and discharged. He was re-admitted with the same symptoms. Further evaluation confirmed the presence of CAH as well. We report this case because of the rarity of this combination (NBS plus CAH) and to the best of our knowledge this is the first such case report from Pakistan.
