    Full Text Available Con el objetivo de establecer la variabilidad genética de Aedes aegypti determinada por el análisis del gen mitocondrial ND4, se analizaron 51 especímenes de Ae. aegypti en once regiones endémicas para dengue en el Perú. La variabilidad genética se determinó mediante la amplificación y secuenciación de un fragmento de 336 pares de bases del gen mitocondrial ND4. El análisis de filogenia intraespecífica se realizó con el programa Network Ver. 4.6.10; y el análisis filogenético, con el método de distancia Neighbor Joining. Se identificó la presencia de cinco haplotipos de Ae. aegypti agrupados en dos linajes: el primero agrupa a los haplotipos 1, 3 y 5 y el segundo agrupa los haplotipos 2 y 4, se muestra además la distribución geográfica de cada uno de los haplotipos encontrados. Se concluye que esta variabilidad se debe tanto a la migración activa de este vector como a la migración pasiva mediada por la actividad humana.

    Full Text Available Mediante la técnica de Udenfriend y Cooper, se midieron los niveles de tirosina en la sangre del cordón de 26 prematuros y 31 niños de término, con el fin de comparar las concentraciones según la edad gestacional y detectar la presencia de la tirosinemia neonatal. Se encontró un caso de esta entidad en un niño de 31 semanas de edad gestacional, lo cual correspondió al 3.8% de los prematuros y al 1.8% del grupo total. La concentración de tirosina en el paciente fue de 53 JJ.M. El promedio de las concentraciones en los prematuros menores de 32 semanas fue de 16.8 :t 6.3 JJ.M; el de los niños entre 33 y 36 semanas fue de 19.3 :t 7.6 JJ.M y el de los niños de término, de 17.2 :t 9.4 JJ.M. Las pruebas estadísticas no mostraron tendencias ni diferencias significativas entre estas concentraciones. El promedio ponderado para el grupo total fue 17.7 :t 7.3 JJ.M. Se recomienda establecer programas de tamizaje para detectar este problema porque puede presentar repercusiones neurológicas posteriores.

    Neonatal arrhythmias are not uncommon; however, they rarely cause hemodynamic compromise. This paper aims to study the etiology, spectrum and outcome of neonates with arrhythmias who presented to a pediatric department. All neonates, either inborn or brought to the pediatric emergency with rhythm disorders, between August 1999 to August 2002, were included prospectively. Evaluation including a search for secondary causes of rhythm disorder and a chest X-ray, standard 12-lead electrocardiography and echocardiography in all. The management required in each and the outcomes were noted. Nine neonates were identified, of which 4 were inborn. Tachycardia was seen in 8 neonates and bradycardia in only one. Three neonates had an antenatal onset of arrhythmias; in the rest it was postnatal in onset. Five neonates had a secondary rhythm disorder, secondary to metabolic derangements in 4 and a cardiac mass in 1. Five had ventricular arrhythmias and 5 had hemodynamic compromise due to the arrhythmia. The outcome was poor in 4 and was related to the underlying illness. Tachyarrhythmia is more common than bradyarrhythmia in the neonate. Arrhythmias secondary to various metabolic causes are more common than primary rhythm disorders.

    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

    Full Text Available Objective. This article analyzes the time-trends and causes of infant, neonatal, and postneonatal mortality in Mexico during the 1980’s. Material and methods. Data on infant deaths came from yearly tabulations (1980 to 1990 published by the Mexican government. Time-trends of mortality rates were determined by simple linear regression models. The parallelism test was performed for evaluating similarities in trends in neonatal and postneonatal mortality rates by causes. Results. During the 1980’s, infant mortality rates in Mexico declined from 40.4 to 31.1/1 000 (ß= -0.791. Postneonatal mortality rates showed a strong decrease (ß= -0.892, while neonatal mortality rates were almost stationary (ß= 0.089. Significant rate decreases were observed for Intestinal infections, Pneumonia and influenza and all other causes while Certain perinatal problems, Congenital defects and Nutritional deficiencies increased. No changes were observed in Acute respiratory infections. The neonatal proportional mortality showed an incremental trend accounting for 37.6% in 1980 and ascending to 48.8% in 1990 of the mortality in the first year of life. Conclusions.This analysis indicates that the reduction in infant mortality in Mexico during the 1980’s was due to declining postneonatal mortality while neonatal mortality rates remain almost unchanged.Objetivo.

    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.

  15. 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 An algorithm of mathematical programmation for the optimum disign of iso-static articulate structures has been developed. The characteristics of the proposed algorithm are: a It not requires that the objective function or the restriction equations be derivable. b They use unidimensional methods of unidimensional optimization to pass over from a given solution to a better one. c To introduce contingent procedures to obtain Information which leads to a better solution. Those characteristics make it specially recommended for non-explicit functions, costly in its evaluation with a great deal of relative minimums. The method is explained by two examples of optimal design of statiscally determined articulated structures.Se ha desarrollado un algoritmo de programación matemática para el dimensionamiento óptimo de estructuras articuladas isostáticas. El algoritmo propuesto se caracteriza por: a No requerir que la función objetivo o las ecuaciones de restricción sean derivables. b Utilizan métodos de optimización unidimensionales para pasar de una solución dada a otra mejor, c Introducir procedimientos aleatorios para obtener información que conduce a una solución mejor. Estas características lo hacen especialmente indicado para funciones no explícitas, costosas en su evaluación y con gran cantidad de mínimos relativos. Se ilustra el método con dos ejemplos de diseño óptimo de estructuras articuladas estáticamente determinadas.

    Neste trabalho foram investigados os efeitos de dois anestésicos locais, lidocaína e benzocaína, sobre as propriedades estruturais e dinâmicas de vesículas unilamelares de fosfatidilcolina de ovo em pH 7,4 e 10,5 para determinar a localização preferencial destes anestésicos no interior da bicamada. Mudanças na organização de vesículas unilamelares pequenas foram determinadas através de espectroscopia de infravermelho com transformada de Fourier. Os experimentos de infravermelho mostraram que os anestésicos locais alteram as ligações de hidrogênio das moléculas de água monitoradas através das regiões da cadeia acila, grupamento fosfato e carbonilas da região do glicerol dos fosfolipídios. Os efeitos do aumento da concentração dos anestésicos locais nestas regiões mostraram que a lidocaína ionizada torna maior o acesso de moléculas de água nas regiões do grupamento de fosfato e carbonilas da região do glicerol. Para a lidocaína neutra (pH 10,5 o principal efeito observado foi na região do glicerol. Já para o anestésico local benzocaína foi observada uma diminuição do acesso de moléculas de água na região das carbonilas do glicerol. Um modelo proposto indica que a lidocaína ionizada e a neutra ligam-se aos lipídios próximos ao grupamento fosfato e região do glicerol. Para a benzocaína a localização preferencial proposta foi a região do glicerol e os primeiros carbonos da cadeia acila. A posição preferencial dos anestésicos nas membranas fosfolipídicas modelo pode modular o acesso destas moléculas em seus sítios de ligação na proteína canal de sódio voltagem-dependente.

    OBJECTIVE: To warn pediatricians about the early recognition of cholestasis in newborns and infants. METHODS: A bibliographic research about cholestasis was performed using Medline, and emphasizing the most relevant publications of the last 30 years. RESULTS: The concept of cholestasis and the causes of cholestatic tendency in newborns and infants are described. Several causes of intra and extrahepatic cholestasis are reported as well. In this review, only the diseases with diagnostic, therapeutic or prognostic peculiarities are commented, including extrahepatic biliary atresia, idiopathic neonatal hepatitis, galactosemia, and Alagille s syndrome. Furthermore, several resources are discussed for the diagnosis of cholestasis. CONCLUSIONS: The establishment of the diagnosis of cholestasis through the detection of hyperbilirubinemia in newborns who present jaundice after 14 days of life is a goal that could change the prognosis of several diseases responsible for neonatal cholestasis.

    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

    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

    masculino provenientes da Maternidade Escola Januário Cicco em Natal, Rio Grande do Norte. A deficiência da glicose-6-fosfato desidrogenase foi determinada através do método qualitativo da redução da metahemoglobina (teste de Brewer e confirmada mediante determinação espectrofotométrica quantitativa da atividade da G6PD e pela eletroforese da enzima em acetato de celulose. Oito recém-nascidos apresentaram deficiência da G6PD, e quatro deles exibiram icterícia nas primeiras 48 horas depois do nascimento, com valores de bilirrubina maiores de 10 mg/dL. Todos os deficientes apresentaram a variante A-. Os dados encontrados confirmam a associação da deficiência da G6PD e a icterícia neonatal. Assim sendo, o diagnóstico precoce da deficiência logo após o nascimento é essencial ao controle do aparecimento da icterícia e para evitar o contato destes recém-nascidos com conhecidos agentes hemolíticos.

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.

    1987-01-01

    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 Las convulsiones del período neonatal y del primer año de vida pueden tener un origen, un tratamiento y un pronóstico muy distintos y serán el neonatólogo y el neuropediatra quienes mejor las conozcan y manejen con mayor experiencia. Existen formas graves de encefalopatía epiléptica del período neonatal como el Sídrome Ohtahara o la encefalopatía mioclónica de Aicardi, con un pronóstico muy reservado y una elevada morbimortalidad. Además existen algunas formas de convulsiones y epilepsias del período neonatal y del lactante joven que no responden al empleo de fármacos antiepilépticos (FAEs. En esta situación el iniciar precozmente otro tipo de terapia puede evitar el deterioro neurológico que, sin duda debido a las crisis convulsivas, se producirá y podrá permitir al paciente llevar una vida normal con la única obligación de tomar de por vida una medicación distinta de los FAEs. Revisamos el grupo de defectos metabólicos que dan lugar a convulsiones y epilepsias y cuyo tratamiento es muy distinto al de una epilepsia. Incluimos en esta revisión algunas formas de convulsiones y epilepsias del lactante joven que tienen en la actualidad tratamiento efectivo mediante sustancias totalmente distintas de los FAEs.Convulsions appearing in the neonatal or first year of life can have a very different origin, treatment or prognosis and it shall be up to the neonatologist or neuropediatrician to resolve the problem since they are the ones who know their patients best. There are severe forms of epileptic encephalopathy in the neonatal period such as Ohtahara syndrome or Aicardi myoclonic encephalopathy with poor prognosis and high morbimortality. Furthermore, there are forms of convulsions and epilepsies during the neonatal and infant period which do not respond to AED. In such cases, it is important to initiate as soon as possible another type of treatment to prevent a neurological deterioration due to repeated convulsion crises and

    Full Text Available Orbital abscess generally occurs in older children but it can rarely affect infants and neonates too. We report a case of community acquired methicillin resistant staphylococcus aureus (CA-MRSA neonatal orbital abscess in a 12-day-old term female neonate with no significant past medical history or risk factor for developing the infection. The case highlights the importance of consideration of CA-MRSA as a causative agent of neonatal orbital cellulitis even in a neonate without any obvious predisposing condition. Prompt initiation of appropriate medical therapy against MRSA and surgical drainage of the abscess prevents life threatening complications of orbital cellulitis which more often tend to be fatal in neonates.

    2007-09-01

    The greatest risk of death from pneumonia in childhood is in the neonatal period. It is estimated that pneumonia contributes to between 750000-1.2 million neonatal deaths annually, accounting for 10% of global child mortality. Congenital and neonatal pneumonias are often a difficult disease to identify and treat, with clinical manifestations often being non-specific. Many of the normal lung defences are compromised in the fetus and neonate, leading to an increased susceptibility to infection. The aetiology and epidemiology of congenital and neonatal pneumonias will depend on the clinical setting and population that the baby belongs to, the stage in the perinatal period, the gestational age of the baby and the definition of pneumonia. Diagnosis, treatment and prevention strategies are therefore also dependent on these factors, and will differ depending on the clinical setting. This review summarizes the current knowledge concerning congenital and neonatal pneumonia worldwide and discusses future directions in the prevention of the disease.

    Full Text Available Laser cladding is one of the most promissing techniques to restore damaged surfaces and achieve properties similar to those of the base metal. In this work, duplex stainless steels have been cladded by a nickel alloy under different processing conditions. The influence of the beam speed and defocusing variables has been evaluated in the microstructure both of the cladding and heat affected zone, HAZ. These results have been correlated to mechanical properties by means of microhardness measurements from cladding area to base metal through the interface. This technique has shown to be very appropriate to obtain controlled mechanical properties as they are determined by the solidification microstructure, originated by the transfer of mass and heat in the system.

    La posibilidad de restaurar superficies y, con ello, las propiedades de las mismas mediante el recubrimiento por láser de polvos constituye uno de los mayores intereses en las investigaciones actuales. En este trabajo se ha obtenido un recubrimiento de una aleación base níquel, mediante el tratamiento láser de polvos elementales para diferentes condiciones de procesado. Se ha evaluado la influencia de las variables de proceso, velocidad del láser y desenfoque del haz láser en la microestructura de los recubrimientos y con ello en las propiedades finales de los mismos, así como en la transición de estas a través de la interfase y la zona afectada por el calor, ZAC, evaluada mediante perfiles de microdureza. La obtención de recubrimientos a partir de polvos resulta muy adecuada, en este caso, al obtener unas propiedades mecánicas que están determinadas por la microestructura de solidificación, originada por la transferencia de masa y calor en el sistema.

    Full Text Available Considerando a natureza sutil dos achados mamográficos, é importante conhecermos como a detectabilidade de pequenos objetos, como fibras e microcalcificações, normalmente presentes em imagens mamográficas, pode ser influenciada pela intensidade luminosa do negatoscópio utilizado nas leituras. Nosso objetivo foi verificar como a luminância pode alterar a detectabilidade de objetos simulados. Foram feitas sete imagens com diferentes intensidades de exposição em duas condições técnicas usando um simulador que permite avaliações estatísticas. Os resultados foram computados usando uma escala de cinco níveis de confiança (100 se o especialista tem certeza da presença do objeto; 75 se provável a presença do objeto; 50 se incerta; 25 se improvável; zero se definitivamente ausente. As imagens foram interpretadas por especialistas que utilizaram negatoscópios "padrões" e específicos para imagens mamográficas. As detectabilidades foram estatisticamente comparadas entre si para cada tipo de negatoscópio por meio do teste do qui-quadrado de Pearson (p < 0,05. A detectabilidade variou de 0,79 a 0,87. Pudemos concluir que a detectabilidade dos objetos, determinada por meio de objetos simulados, é superior para os negatoscópios específicos para mamografias quando comparada aos negatoscópios "padrões" amplamente utilizados na radiologia geral.

    Lung diseases represent one of the most life threatening conditions in the newborn. Important progresses in modern perinatal care has resulted in a significantly improved survival and decreased morbidity, in both term and preterm infants. Most of these improvements are directly related to the better management of neonatal lung conditions, and infants of very low gestational ages are now surviving. This article reviews the common spectrum of diseases of the neonatal lung, including medical and surgical conditions, with emphasis to the radiological contribution in the evaluation and management of these infants. Imaging evaluation of the neonatal chest, including the assessment of catheters, lines and tubes are presented.

Para ello, se realizaron (en reposo y ojos cerrados registros EEG digitales monopolares (256 Hz de frecuencia de muestreo referenciados al promedio de 16 canales/electrodos (6-frontales, 4-temporales, 2-centrales, 2-parietales, 2-occipitales. Estimamos la conectividad entre canales mediante la función de coherencia en las bandas de frecuencia delta/theta/alfa/beta, y mediante un índice (L de sincronización no lineal generalizada. Analizamos la conectividad individual entre todos los pares posibles de canales y la conectividad global de cada canal con el resto. Los resultados muestran que determinadas interdependencias individuales medidas por el índice L y por la coherencia en banda-delta, decrecen con la edad, especialmente para las conexiones centro-temporales-occipitales. Además, se observa un decrecimiento lineal significativo con la edad de los índices de interdependencia señalados,especialmente para las parejas y promedios individuales de las zonas señaladas. También las interdependencias globales, especialmente las de tipo no lineal, de ciertas zonas centro-laterales y posteriores declinan con la edad. Concluimos que, medidas individuales y globales de conectividad funcional EEG entre determinadas áreas corticales pueden ayudar a valorar objetivamente el envejecimiento neurofisiológico.

    Full Text Available Prominence or even enlargement of one or both breasts is known in neonates. It is believed to be a physiological response to falling levels of maternal estrogen towards last trimester of pregnancy. This input stimulates prolactin release from the newborn's pituitary leading to transient neonatal breast enlargement. This phenomenon is independent of the gender of the neonate. It presents in the first few weeks of life and resolves subsequently. Often fluid discharge is noted from the prominent or swollen breast that resolves without treatment in subsequent weeks. Manual breast manipulation for discharge removal may lead to undesirable effects like local irritation, enhanced enlargement, prolonged tissue hypertropy or even mastitis. A case of such 7-days female neonate is presented here backed with imaging evaluation for confirmation of diagnosis. Typical sonomammographic findings are described.

    A cohort study of neonatal mortality (N = 106) in white singleton births (N = 14,486) in Utah for January-June 1975 was conducted. 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.

    Maternal and neonatal tetanus is still a substantial but preventable cause of mortality in many developing countries. Case fatality from these diseases remains high and treatment is limited by scarcity of resources and effective drug treatments. The Maternal and Neonatal Tetanus Elimination Initiative, launched by WHO and its partners, has made substantial progress in eliminating maternal and neonatal tetanus. Sustained emphasis on improvement of vaccination coverage, birth hygiene, and surveillance, with specific approaches in high-risk areas, has meant that the incidence of the disease continues to fall. Despite this progress, an estimated 58 000 neonates and an unknown number of mothers die every year from tetanus. As of June, 2014, 24 countries are still to eliminate the disease. Maintenance of elimination needs ongoing vaccination programmes and improved public health infrastructure. PMID:25149223

    The neonatal asphyxia is recognized as an important cause of morbidity and mortality during the pediatric age. The objective of this study was to evaluate the correlation between some neonatal variables and neurological outcome at two years of life in infants with asphyxia, in order to produce a correct prognosis and to grant a rapid and targeted therapy. We have recruited 63 patients whose history and neuroimages suggested a neonatal asphyxia, and we have analysed their clinical- instrumental parameters every three months until two years of life. A correlation study was carried out in order to find a statistical significance indicated by p-value Neonatal seizures are not related to an increased risk to develop epilepsy. Epilepsy alone is a rare event and it usually complicates CP picture. Most subject with both epilepsy and CP are term infants with adequate weight. Preterm VLBW infants have a greater risk to develop a psychomotor delay. Clinical conditions at birth are related to CP severity (several neonatal neurological signs are the greater risk factors). Severely pathological neonatal EEG (background activity) is related to CP severity and an early symptomatic epilepsy onset is related with both epilepsy and CP severity.

  19. Selección de cartera mediante escenarios con dotación inicial indeterminada

    1999-01-01

    Full Text Available Los modelos media-varianza de selección de cartera, y en general los basados en el binomio rentabilidad-riesgo, parten de un capital inicial cierto. La consideración de la aversión al riesgo en los mismos es indirecta y siempre referida al valor final de la cartera, así que por lo general lo que se determina en los mismos es la proporción de la inversión total o riqueza inicial que se destina a cada activo considerado. Sin embargo, en muchas situaciones reales la aversión al riesgo debe considerarse ya en el momento de invertir, por lo que la determinación de la cuantía a invertir, coste o dotación inicial forma parte del problema, considerando que será mayor, dentro de unas cotas, si existe la probabilidad de obtener mayor rentabilidad aún soportando mayor riesgo. El problema se presenta mediante un modelo simple, pero general en su planteamiento, en el que además de la composición de la cartera queda determinada la cantidad a invertir. La idea es que el inversor establece dos capitales, uno como mínimo y otro como máximo, que está dispuesto a invertir y se utiliza la optimización por escenarios para decidir qué cantidad, entre las dos anteriores, le conviene invertir según sus expectativas.

    Full Text Available Neste trabalho estudamos as alterações histopatológicas encontradas no sistema nervoso central de dois pacientes com "panencefalite subaguda esclerosante" comparando-as com as modificações estruturais determinadas no sistema nervoso central de sete macacos rhesus nos quais este material foi inoculado. Os animais apresentaram sinais de comprometimento neurológico, traduzido por caquexia e paralisia do trem posterior, após um longo período de incubação, em torno de 18 meses. Dois animais morreram antes de qualquer manifestação neurológica, de infecção pulmonar intercorrente acidental. Nas passagens sucessivas houve um encurtamento do periódo de incubação para cerca de 40 dias. As alterações histopatológicas encontradas, consistiram, nos casos humanos, em leptomeningite focal, focos de neuronofagia, granulomas corticais e nos núcleos basais, grande perda da população neuronal com ocasional estado esponjoso do córtice cerebral, infiltrados perivasculares, e gliose da substância branca, sem perda de mielina. No material experimental foram observadas estas mesmas modificações, se bem que de caráter muito menos intenso. Tanto no material humano como no experimental a mielina estava praticamente normal. Sugere-se que o quadro anátomo-clínico chamado "panencefalite subaguda esclerosante (SSPE possa ser determinado, não apenas pelo vírus do sarampo, mas também por outros vírus, especialmente os do grupo papova, já encontrado por outros autores, em casos de "panencefalite subaguda esclerosante".The authors describes the histopathological changes found in the central nervous system of two patients with subacute sclerosing panencephalitis. These lesions are compared to those found in the central nervous system of seven rhesus monkeis that had received inoculations of nervous tissue from the two patients. After an incubation period of approximately 18 months, the monkeys presented signs of damage to the nervous system

    Full Text Available A correta quantificação da concentração de lignina em plantas forrageiras, pelo método espectrofotométrico, pressupõe a existência de um padrão de referência. Um padrão de referência deve ter composição fenólica semelhante à da lignina da parede celular. O objetivo deste trabalho foi verificar se ligninas extraídas com solução ácida de dioxano para serem utilizadas como padrão de referência, apresentariam variação na composição fenólica da mesma maneira que a lignina da parede celular. Amostras de parede celular de "bromegrass", milho e trevo-vermelho foram submetidas ao método para extração de ligninas com solução ácida de dioxano. A composição fenólica das ligninas foi analisada mediante oxidação alcalina pelo nitrobenzeno com posterior separação dos componentes monoméricos via HPLC. As ligninas extraídas confirmaram a existência de variação na composição fenólica da mesma maneira às ligninas intactas presentes na parede celular e de substancial presença de ácidos cinâmicos nas ligninas de gramíneas. No que diz respeito à composição fenólica, ligninas extraídas com solução ácida de dioxano podem ser consideradas potenciais padrões de referência paras as análises espectrofotométricas.

  2. Neonatal nonimmune hemolytic anemia.

    2017-02-01

    As in adults and older children, anemia in newborn infants can be the result of erythropoietic failure, hemorrhage, or hemolysis. When hemolysis is the prime consideration, it can be challenging for physicians caring for neonates to choose from the wide variety of available diagnostic tests. This review describes the authors' opinions regarding rational, consistent, and cost-effective means of making an exact diagnosis of a neonatal hemolytic condition. Two recent advances in the diagnosis of neonatal nonimmune hemolytic disorders are highlighted in this review: introduction of flow cytometry-based Eosin-5-maleimide (EMA) uptake as a screening test to identify RBC membrane defects and next-generation sequencing (NGS)-based panels to uncover exact mutations causing hemolysis. The availability of newer tools such as EMA and NGS to diagnose specific hemolytic conditions, which might otherwise remain unknown, enables neonatal practitioners not only to identify the exact cause of hemolysis but also to discover novel mutations that can be implicated in the cause of neonatal hemolytic processes.

    2017-02-01

    Infections (including sepsis, meningitis, pneumonia and tetanus) stand as a major contributor to neonatal mortality in Haiti (22%). Infants acquire bacteria that cause neonatal sepsis directly from the mother's blood, skin or vaginal tract either before or during delivery. Nosocomial and environmental pathogens introduce further risk after delivery. The absence of cohesive medical systems and methods for collecting information limits the available data in countries such as Haiti. This study seeks to add more information on the burden of severe bacterial infections and their etiology in neonates of Haiti. Researchers conducted a secondary retrospective analysis of a de-identified database from the Neonatal Intensive Care Unit (NICU) at Nos Petit Frères et Soeurs-St. Damien Hospital (NPFS-SDH). Records from 1292 neonates admitted to the NICU at NPFS-SDH in Port-au-Prince Haiti from 2013 to 2015 were reviewed. Sepsis accounted for 708 of 1292 (54.8%) of all admissions to the NICU. Infants admitted for sepsis had a mortality rate of 23% (163 of 708 infants admitted for sepsis). The most common organism cultured was Streptococcus agalactiae, followed by Klebsiella pneumoniae, Pseudomonas aeroginusa, Enterobacter aerogenes, Staphylococcus aureus and Proteus mirabillis Failure to order or obtain a culture was associated with an increased fatality (odds ratio 2.4) for infants with sepsis. Resistance should be a concern when treating empirically. © The Author [2016]. Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

    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.

    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

    ANTECEDENTES: la obesidad infantil es un proceso que involucra en sí mismo un estrés oxidativo y un estado inflamatorio crónico que estimula la producción de corticosteroides, promueve la aparición temprana de resistencia insulínica y de enfermedades como la diabetes mellitus tipo 2.  OBJETIVO: evaluar la composición corporal en población infantil costarricense mediante técnicas de dilución isotópica con deuterio y analizar su relación con el índice de resistencia a la insulina y niveles de cortisol sérico matutino.  MATERIALES Y MÉTODOS: determinación de cortisol sérico matutino y resistencia a la insulina mediante el método homeostático en 113 niños y niñas escolares. Se realiza la comparación por grupos según la clasificación McCarthy para porcentaje de masa grasa, determinada mediante el método de dilución isotópica. RESULTADOS: no se observan diferencias estadísticamente significativas entre los grupos de masa grasa, según la clasificación McCarthy para las variables de cortisol sérico matutino e índice HOMA (modelo homeostático de resistencia a la insulina, en la muestra seleccionada. CONCLUSIÓN: en niños y niñas entre 6 y 9 años de edad no se evidencian las características bioquímicas que se esperan del síndrome metabólico, dada la poca exposición temporal al estrés oxidativo que produce la obesidad, determinada por medio de la medición de masa grasa con un método temprano como la dilución isotópica. Asimismo, en edades tempranas los mecanismos de detoxificación renal de los corticosteroides son suficientes para evitar su elevación sérica, protegiendo al niño de sus efectos a largo plazo.

    Full Text Available En la actualidad existen dos variantes principales de vacunas orales contra el cólera: una basada en células inactivadas de diferentes biotipos y serotipos y otra basada en la administración de cepas vivas genéticamente atenuadas. Una vacuna por subunidades pudiera ser una variante muy atractiva. Este trabajo describe la purificación parcial y caracterización preliminar de extractos de proteínas de membrana externa-lipopolisacárido (PME-LPS, obtenidos a partir de Vibrio cholerae O1, con el interés de seleccionar un proteoliposoma que posteriormente será estructurado en forma de cocleatos para su uso por vía oral en humanos. Las preparaciones fueron obtenidas a través del uso de diferentes detergentes. La cantidad de LPS en cada preparación fue estimada mediante la determinación de las unidades endotóxicas en el ensayo del Limulus (LAL. La composición de cada muestra fue evaluada mediante SDS-PAGE y Dot Blot. La inoculación intranasal (IN en ratones Balb/c se utilizó para la evaluación de la inmunogenicidad de las preparaciones, y la respuesta inmune fue determinada por ELISA y el título de anticuerpos vibriocidas. El tamaño molecular de la preparación con mejores resultados en inmunogenicidad se estimó mediante la cromatografía en Sephacryl S-1000. Se obtuvieron diferentes perfiles electroforéticos de acuerdo con el tipo de detergente utilizado. El LPS fue identificado en todas las preparaciones y aquella obtenida con el SDS al 15% mostró la más baja relación proteínas/LPS y los mejores resultados en los ensayos de inmunogenicidad. Adicionalmente se comprobó que su tamaño molecular es similar al observado en el proteoliposoma de VAMENGOC- BC. La preparación obtenida con el SDS al 15% constituye un proteoliposoma, con capacidad para estimular altos niveles de anticuerpos IgG anti-LPS y altos títulos de anticuerpos vibriocidas, luego de su administración por vía intranasal en ratones. Estos resultados constituyen

    During pregnancy, it is not always possible to identify maternal or foetal risk factors. Infants requiring specialised medical care are not always born in centres providing intensive care and will need to be transferred to a referral centre where intensive care can be provided. Therefore Neonatal Transport needs to be considered as part of the organisation of perinatal health care. The aim of Neonatal Transport is to transfer a newborn infant requiring intensive care to a centre where specialised resources and experience can be provided for the appropriate assessment and continuing treatment of a sick newborn infant. Intrauterine transfer is the ideal mode of transport when the birth of an infant with risk factors is diagnosed. Unfortunately, not all problems can be detected in advance with enough time to safely transfer a pregnant woman. Around 30- 50% of risk factors will be diagnosed during labour or soon after birth. Therefore, it is important to have the knowledge and resources to resuscitate and stabilise a newborn infant, as well as a specialised neonatal transport system. With this specialised transport it is possible to transfer newly born infants with the same level of care that they would receive if they had been born in a referral hospital, without increasing their risks or affecting the wellbeing of the newborn. The Standards Committee of the Spanish Society of Neonatology reviewed and updated recommendations for intrauterine transport and indications for neonatal transfer. They also reviewed organisational and logistic factors involved with performing neonatal transport. The Committee review included the type of personnel who should be involved; communication between referral and receiving hospitals; documentation; mode of transport; equipment to stabilise newly born infants; management during transfer, and admission at the referral hospital.

    Diffuse neonatal gastric infarction can be a devastating complication of invasion of the gastric wall and vessels by fungi colonizing the gastric mucosa. Even in the presence of extensive transmural necrosis, however, the radiographs do not necessarily show evidence of gastric mucosal abnormality. Instead, plain films and positive contrast studies may erroneously suggest a mechanical gastric outlet obstruction. Ancillary evidence of a devitalized viscus in a baby who appears to have complete gastric outlet obstruction should suggest the diagnosis of gastric infarction. (orig.)

    2004-04-01

    Full Text Available Carbon nitride films have been deposited by ECR-CVD, from Ar/CH4/N2 gas mixtures with different methane concentrations. Infrared Spectroscopy (IRS and Elastic Recoil Detection Analysis (ERDA have been used for films characterisation and Optical Emission Spectroscopy (OES for plasma analysis. Argon concentration in the gas mixture controls the growth rate as well as the composition of the film. In the proposed model, argon plays a key role in the activation of methane molecules. Also, during the growth of the film, two processes may be considered: i Film formation and ii Etching of the growing surface. Changing the gas mixture composition affects both processes, which results in films with different composition and structure as well as different deposition rates.Se ha estudiado el efecto del argon durante el proceso de CVD asistido por un plasma ECR para la síntesis de películas de nitruro de carbono (CNxHy a partir de mezclas gaseosas Ar/CH4/N2 con diferente contenido de metano. Las películas depositadas han sido analizadas mediante espectroscopía infrarroja (IRS y ERDA (Elastic Recoil Detection Analysis, y el análisis del plasma ha sido realizado utilizando la técnica de espectroscopía de emisión óptica (OES. La velocidad de deposición y la composición de las películas depositadas se encuentran determinadas por la concentración de argon en la mezcla gaseosa. Se propone un modelo, según el cual el argon juega un papel fundamental como activador de las moléculas de metano. El modelo propuesto incluye dos procesos simultáneos durante el crecimiento de las capas : i formación de la capa y ii ataque de la superficie de crecimiento. Según la composición de la mezcla gaseosa se favorece uno u otro proceso, lo que conduce a velocidades de deposición diferentes así como a depósitos con diferente composición y estructura atómica.

    Cardiac arrhythmias are an important aspect of fetal and neonatal medicine. Premature complexes of atrial or ventricular origin are the main cause of an irregular heart rhythm. The finding is typically unrelated to an identifiable cause and no treatment is required. Tachyarrhythmia most commonly relates to supraventricular reentrant tachycardia, atrial flutter, and sinus tachycardia. Several antiarrhythmic agents are available for the perinatal treatment of tachyarrhythmias. Enduring bradycardia may result from sinus node dysfunction, complete heart block and nonconducted atrial bigeminy as the main arrhythmia mechanisms. The management and outcome of bradycardia depend on the underlying mechanism. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

    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.

  12. Neonatal gastrointestinal imaging

    International Nuclear Information System (INIS)

    2006-01-01

    Radiological imaging is an important part of the evaluation and management of neonates with suspected anomalies of the gastrointestinal tract. Clinical presentation is often non-specific, commonly with abdominal distension and vomiting for which the underlying cause may or may not be clinically apparent. In a proportion of patients, the clinical assessment alone may suffice in providing the diagnosis and no further imaging is necessary. The reader must have an understanding of the normal radiographic appearances of the gastrointestinal tract in neonates and appreciate normal variants and differences to adults. In certain cases, the abdominal radiograph alone is diagnostic. In others, sonography and contrast studies are useful adjunct investigations and the indications for CT and MRI are few, but specific. Appropriate radiological investigation will help to establish the diagnosis and guide surgical intervention whilst also avoiding unnecessary radiation. Some of the conditions require transfer to specialist paediatric institutions for care. Thus, in some circumstances it is appropriate for imaging to be delayed and performed at the specialist centre with early referral often essential for the continued well being of the child

    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.

    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

    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

    The case of a neonate is presented who had late onset seizure associated with hypocalcemia, hyperphosphatemia, and raised parathyroid hormone. The infant did not have any stigmata of pseudohypoparathyroidism. The hypocalcemia was initially resistant to calcium therapy, but responded to vitamin D analog therapy. The diagnosis of 'transient neonatal pseudohypoparathyroidism' was entertained, as the infant remained stable and seizure-free with normal serum biochemistry during 8 months of follow-up.

    Coccidia were identified in intestinal sections from 82 piglets comprising 37 consignments from 34 farms, and represented a yearly increasing incidence in the three years 1978 to 1980. Piglets were primarily from medium to large farms with intensive, continuous-farrowing, confinement-rearing programs. Piglets, usually five days to 15 days old, had yellow, fluid diarrhea, became unthrifty and sometimes died. In six piglets from two farms, a green, adherent, fibrinonecrotic membrane was seen throughout most of the jejunum and ileum. Significant gross lesions were not observed in the other 76 piglets. Moderate to severe villous atrophy of jejunum and ileum was seen histologically. Various asexual and sexual stages of coccidia were seen within parasitophorous vacuoles of villar epithelial cells. Multifocal erosions with necrosis of villar tips and occasionally more diffuse mucosal necrosis with fibrinocellular exudate were seen. Isospora suis oocysts were identified in feces from several weaners from one farm. Amprolium and decoquinate mixed in the sow ration at 1 kg/tonne for three weeks prior to and postfarrowing was moderately successful in stopping outbreaks of neonatal diarrhea associated with coccidiosis.

    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

    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

  12. Fetal and neonatal thyrotoxicosis

    2013-01-01

    Full Text Available 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 20 th week of pregnancy and reaches its maximum by 30 th 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.

    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.

    Arrhythmias in the neonatal period are not uncommon, and may occur in neonates with a normal heart or in those with structural heart disease. Neonatal arrhythmias are classified as either benign or nonbenign. Benign arrhythmias include sinus arrhythmia, premature atrial contraction, premature ventricular contraction, and junctional rhythm; these arrhythmias have no clinical significance and do not need therapy. Supraventricular tachycardia, ventricular tachycardia, atrioventricular conduction...

    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.

  15. Photodegradation of riboflavin in neonates

    Sisson, T.R.

    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 Neonatal septicemia is a major cause of mortality and morbidity in horses in their first seven days of life and within their pathophysiology. It is important to consider the extrinsic and intrinsic predisposing factors which make foals susceptible to agents of primarily bacterial etiology. However, other types of infectious etiology (viruses and fungi should be considered too, as well as noninfectious etiologies. The paper mentions a wide variety of mechanisms that produce different injuries that must be addressed with measures of critical neonatal care, so it is imperative for the veterinarian to know the pathogenic mechanisms of the disease, its clinical presentation and anatomo-pathological lesions. Thus, systemic inflammatory response syndrome (SIRS, multiple organ dysfunction syndrome (MODS, and peripheral circulatory collapse or shock are some of the elements defined as the pillars of the pathophysiology of neonatal septicemia, extensively studied in equine medicine. This paper presents a short review of the triggering mechanisms of neonatal septicemia highlighting the importance of epidemiological investigations in Colombia. It shows the need for retrospective and prospective studies and for divulgation of some of the preventive measures of the disease in horses.

    To assess the accuracy of time perception during a simulated complex neonatal resuscitation. Participants in 5 neonatal resuscitation program courses were directly involved in a complex simulation scenario. They were asked to assume the role of team leader, assistant 1, or assistant 2. At the end of the scenario, each participant completed a questionnaire on perceived time intervals for key resuscitation interventions. During the scenario, actual times were documented by an external observer and video recorded for later review. In addition, participants were asked to evaluate their self-perceived level of stress and preparation. Health care providers (68 physicians and 40 nurses) were involved in 36 scenarios. Perceived time intervals for the initiation of key resuscitation interventions were shorter than the actual time intervals, regardless of the participant's role in the scenario. Self-assessed levels of stress and preparation did not influence time perception. Health care providers underestimate the passage of time, irrespective of their role in a simulated complex neonatal resuscitation. Participant's self-assessed levels of stress and preparation were not related to the accuracy of their time perception. These findings highlight the importance of assigning a dedicated individual to document interventions and the passage of time during a neonatal resuscitation. Copyright © 2016 Elsevier Inc.

    Caffeine is a silver bullet in neonatology. This ubiquitous trimethylxanthine, pervasively used in the human diet and beverages, significantly impacts on major acute neonatal morbidities including apnea of prematurity, bronchopulmonary dysplasia, patent ductus arteriousus with or without surgical ligation and post-operative apnea. Potential uses in respiratory distress syndrome as suggested by improved lung function in primate models is supported by the decreased time on mechanical ventilation and need for oxygen therapy. Improved later outcomes at 18 to 22 months include clinically significant decreases in cerebral palsy, cognitive impairment, and severe retinopathy of prematurity in those babies who received caffeine during the neonatal period compared to non-caffeine treated placebo neonates. Ongoing and future research studies focus on optimizing current dose regimens to determine whether benefits can be maximized while maintaining an impressive safety profile. Molecular pharmacologic studies focused on the molecular and the biochemical mechanisms underlying the protective effects of caffeine are also being done to optimize treatment regimes and to target potential molecular pathways leading to further decreases in acute and long term neonatal morbidities. Since its use in newborns three decades ago, caffeine is now one of the safest, most cost-beneficial and effective therapies in the newborn.

    The annual rate of Down syndrome (DS) births in Jerusalem is stable, regardless of prenatal screening, and diagnostic measures. We aimed to evaluate our historical cohort for obstetrical characteristics and the neonatal course and complications. We reviewed computerized medical files of neonates with the diagnosis of DS born in the four main hospitals in Jerusalem between the years 2000 and 2010 and evaluated for maternal history and primary neonatal hospitalization. A total of 403 neonates were diagnosed with DS. The average maternal age was 35.6 years, 73% were born via spontaneous vaginal delivery. In all gestational ages, the mean birth weight and head circumference percentiles were significantly lower than the general population (P < 0.001 for both) and at each week the HC percentile was lower than the weight percentile (P < 0.0001), worse among males. Mortality during the primary hospitalization was 3.7%. The most common anomalies were cardiac (79%) with either congenital defects or functional abnormalities, neither influenced the length of hospitalization. The main reasons for prolonged hospitalization were prematurity and anomalies of other (non-cardiac) organs. Common perinatal complications included respiratory failure or need for oxygen supplementation (32%), hyperbilirubinemia (23%), sepsis (6.4%), and feeding difficulties (13%). About 84% were fed by human milk; of those, two thirds were exclusively breast-fed and one third were supplemented with infant formula. In conclusion, infants with DS were small for gestational age with relatively reduced head circumference. Despite the increased rate of congenital anomalies and perinatal complications, most infants were discharged home in good medical condition and were exclusively breastfed. © 2017 Wiley Periodicals, Inc.

    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.)

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

    Pisani, Francesco; Spagnoli, Carlotta

    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.

    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.

    Lenticulostriate vasculopathy (LSV) is sometimes detected as stripe-like vascular echogenicities in the region of the basal ganglia on routine brain ultrasonography in neonates. LSV is often associated with various perinatal and neonatal abnormalities. Eight infants had echogenic stripes in the basal ganglia at the location of the lenticulostriate arteries, seen by head ultrasound. One patient had infection with rubella, three had respiratory disease, one with twin to twin transfusion, two with congenital malformation, and one had a restrictive ductus arteriosus in prenatal diagnosis. Brain computed tomography in one sonographically diagnosed LSV case failed to display the lesion. Sonographic follow up of patients with LSV showed progression in one case, no change in six, and resolution of lesions in one case. Sonography is helpful in detecting early noncalcific inflammation and mineralisation in vasculitis. LSV has varied clinical associations. Although nonspecific, these findings should alert the physician to the possibility of congenital infection, chromosomal abnormality, or prenatal drug exposure. (author)

  11. Maternal Preeclampsia and Neonatal Outcomes

    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 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.

    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.) With 6 figs., 1 tab., 13 refs.

  14. Hepatobiliary scan in neonatal Jaundice

    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)

  19. Which biomarkers reveal neonatal sepsis?

    Directory of Open Access Journals (Sweden)

    Kun Wang

    Full Text Available We address the identification of optimal biomarkers for the rapid diagnosis of neonatal sepsis. We employ both canonical correlation analysis (CCA and sparse support vector machine (SSVM classifiers to select the best subset of biomarkers from a large hematological data set collected from infants with suspected sepsis from Yale-New Haven Hospital's Neonatal Intensive Care Unit (NICU. CCA is used to select sets of biomarkers of increasing size that are most highly correlated with infection. The effectiveness of these biomarkers is then validated by constructing a sparse support vector machine diagnostic classifier. We find that the following set of five biomarkers capture the essential diagnostic information (in order of importance: Bands, Platelets, neutrophil CD64, White Blood Cells, and Segs. Further, the diagnostic performance of the optimal set of biomarkers is significantly higher than that of isolated individual biomarkers. These results suggest an enhanced sepsis scoring system for neonatal sepsis that includes these five biomarkers. We demonstrate the robustness of our analysis by comparing CCA with the Forward Selection method and SSVM with LASSO Logistic Regression.

    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.

    Vitamin D is a fat-soluble vitamin that is important for calcium metabolism and plays an important role in the immune functions. The aim of this study was to measure neonatal and maternal 25-OH vitamin D serum levels in neonates with early onset sepsis. The study included fifty neonates with early onset sepsis (25 full-term and 25 preterm infants) and thirty age and sex matched healthy neonates as controls. After history taking and clinical examination, complete blood count, C-reactive protein and 25-OH vitamin D serum levels (neonatal and maternal) were measured for all neonates. The mean gestational age for neonates with sepsis was (37.5 ± 0.98 for full term and 34.1 ± 1.26 for preterm neonates). Neonatal and maternal 25-OH vitamin D serum levels were significantly lower in patients (6.4 ± 1.8 and 24.6 ± 2.2 nmol/L) than controls (42.5 ± 20.7 and 50.4 ± 21.4 nmol/L). Significant negative correlations between neonatal and maternal 25-OH vitamin D serum levels and all sepsis markers and significant positive correlations between neonatal and maternal 25-OH vitamin D levels were present. At cut-off values <20 nmol/L for neonatal and <42 nmol/L for maternal 25-OH vitamin D for detection of neonatal sepsis, the sensitivity, specificity, positive predicted value (PPV) and negative predicted value (NPV) were 84%, 79%, 94.7% and 82.3% for neonatal and 82%, 77%, 91.4% and 80.6% for maternal 25-OH vitamin D, respectively. Positive correlations between neonatal and maternal 25-OH Vitamin D serum levels are present and they are negatively correlated with all sepsis markers. They can be sensitive early predictors for early onset sepsis in neonates.

    Pneumonia due to methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of morbidity and mortality in infants particularly following lower respiratory tract viral infections such as Respiratory Syncytial Virus (RSV). However, the mechanisms by which co-infection of infants by MRSA and RSV cause increased lung pathology are unknown. Because the infant immune system is qualitatively and quantitatively different from adults we developed a model of infant MRSA pneumonia which will allow us to investigate the effects of RSV co-infection on disease severity. We infected neonatal and adult mice with increasing doses of MRSA and demonstrate that neonatal mice have delayed kinetics in clearing the bacteria in comparison to adult mice. There were differences in recruitment of immune cells into the lung following infection. Adult mice exhibited an increase in neutrophil recruitment that coincided with reduced bacterial titers followed by an increase in macrophages. Neonatal mice, however, exhibited an early increase in neutrophils that did not persist despite continued presence of the bacteria. Unlike the adult mice, neonatal mice failed to exhibit an increase in macrophages. Neonates exhibited a decrease in phagocytosis of MRSA suggesting that the decrease in clearance was partially due to deficient phagocytosis of the bacteria. Both neonates and adults responded with an increase in pro-inflammatory cytokines following infection. However, in contrast to the adult mice, neonates did not express constitutive levels of the anti-microbial peptide Reg3γ in the lung. Infection of neonates did not stimulate expression of the co-stimulatory molecule CD86 by dendritic cells and neonates exhibited a diminished T cell response compared to adult mice. Overall, we have developed a neonatal model of MRSA pneumonia that displays a similar delay in bacterial clearance as is observed in the neonatal intensive care unit and will be useful for performing co

    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.

    To determine if the incidence of maternal diabetes mellitus or neonatal macrosomia is more frequent in fetuses and neonates with atrial arrhythmias than the general population. Fetuses and neonates neonates with atrial flutter or ectopic atrial tachycardia were more likely to be macrosomic or be born to diabetic mothers than the general population. Postnatal echocardiography suggests that there may be abnormal diastolic left ventricular filling in some babies with these arrhythmias. Independent of ventricular hypertrophy, we speculate that isolated, non-recurrent fetal or neonatal atrial flutter, or ectopic atrial tachycardia may be caused by cardiac diastolic dysfunction and atrial stretch in utero. © 2013 John Wiley & Sons, Ltd.

    2015-12-01

    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.

    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.

    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)

    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.

Periventricular leukomalacia (PVL is the commonest white matter brain injury in preterm infants. It has a typical distribution at the watershed areas adjacent to the lateral ventricles. PVL occurs because of ischemic injury to periventricular oligodendrocytes of the developing brain. It can be detected by cranial ultrasonography (CUS as initial periventricular echodensities, followed later by cystic formation. Recent magnetic resonance imaging studies have shown that it helps in early visualization of PVL and also detection of non-cystic form of PVL, which is not picked up by CUS. It is the commonest cause of cerebral palsy, intellectual impairment or visual disturbances. Currently, no medical treatment is available for PVL; prevention and close developmental follow-up are the only options.

    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.

  1. Redirecting treatment during neonatal transport.

    2011-01-01

    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.

    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)

    Perfusion of human foetal heart with anti-Ro/SSA antibodies induces transient heart block. Anti-Ro/SSA antibodies may cross-react with T- and L-type calcium channels, and anti-p200 antibodies may cause calcium to accumulate in rat heart cells. These actions may explain a direct electrophysiological effect of these antibodies. Congenital complete heart block is the more severe manifestation of so-called "Neonatal Lupus". In clinical practice, it is important to distinguish in utero complete versus incomplete atrioventricular (AV) block, as complete AV block to date is irreversible, while incomplete AV block has been shown to be potentially reversible after fluorinated steroid therapy. Another issue is the definition of congenital AV block, as cardiologists have considered congenital blocks detected months or years after birth. We propose as congenital blocks detected in utero or within the neonatal period (0-27 days after birth). The possible detection of first degree AV block in utero, with different techniques, might be a promising tool to assess the effects of these antibodies. Other arrhythmias have been described in NL or have been linked to anti-Ro/SSA antibodies: first degree AV block, in utero and after birth, second degree (i.e. incomplete block), sinus bradycardia and QT prolongation, both in infants and in adults, ventricular arrhythmias (in adults). Overall, these arrhythmias have not a clinical relevance, but are important for research purposes.

  5. Radiation therapy in the neonate

    Radiation therapy (RT) is frequently used in the management of children with cancer, but neonatal neoplasms are rare. Newborns represent 1.5% of the children with malignant diseases in the Tumor Registry at the Children's Hospital of Philadelphia over the last 30 years. Thus, occasionally the pediatrics radiation therapist must consider treating the very young infant. The specific radiation effects on growth and development must be weighed in reaching a therapeutic decision. All children are vulnerable to the late effects of radiation therapy, but the neonates may be more susceptible because of the immaturity of important organs such as the brain, lung, liver, kidney, and bone. In general, radiation therapy, should be avoided during the first several weeks of life because of the potential increased sensitivity of the liver and kidneys during that period. If radiation therapy is used at all during infancy, the benefits must be weighed against the possibility of significant late effects. Increasing knowledge of pediatric neoplasms has shown that some tumors (such as mesoblastic nephroma) require no treatment except for surgical excision; and other tumors, such as Stage IV-S neuroblastoma, may require very little treatment. In those tumors that require radiation therapy, the use of chemotherapy may allow reduction of the radiation dose. Furthermore, alterations of time-dose-fractionation schemes and careful attention to tumor volume with the use of special techniques, such as ''shrinking fields,'' may decrease the late adverse effects of treatment

Regarding 9 autopsied cases and 7 cases diagnosed by CT-scan, 10 mature infants composed of 3 subarachnoid hemorrhages, 2 intraventricular hemorrhages, 2 subdural hematomas, 2 intracerebral and 1 subependymal hemorrhage; 6 premature infants consisted of 4 subependymal hemorrhages with ventricular rupture and 2 subarachnoid hemorrhages. Most of them presented with respiratory distress, vomiting and convulsive seizures which developed within 5 days after birth. 3. Poor outcome including death amounted 49% of mature and 63% of premature infants. Along with degree of intracranial hematoma, prematurity and pulmonary complication were felt to be important prognostic factors. 4. Introduction of CT-scan led to prompt diagnosis and treatment, thus lowering mortality rate of neonatal intracranial hemorrhages. (author)

Paediatrics Ward-2, QAMC/BVH, Bahawalpur for 02 years from October 2001 to October 2003. The study included 45 cases of neonatal malaria. Thirty cases of malaria, admitted during first ten days of life, diagnosed as congenital malaria, were kept in group A, while 15 cases admitted in the ward from the age of 11 to 28 days, labeled as acquired malaria, were named group B. The clinical features at the time of presentation were noted in each group from the charts having positive malarial parasite (M.P.) on thick and thin slides. The diagnosed cases were treated with the standard dose of chloroquine sulphate. Those patients who improved clinically as well as revealed no parasite on follow-up were labeled as chloroquine sensitive. On the other hand, patients showing poor clinical response with persistence of the parasites in the blood or initially disappearing but later again having a clinical disease with positive M.P. on follow-up, were labeled as chloroquine resistant. They were treated with quinine sulphate. Outcome was compared in both the groups regarding the pattern of chloroquine resistance and death/ survival. Data was collected on which Fischer's exact test of significance was performed to know the level of significance. P-value of important clinical features. Pattern of chloroquine resistance and mortality in both the groups was not statistically different.

    To identify maternal and neonatal factors associated with prematurity in the municipality of Porto Alegre. This was a population-based case-control study. The cases were newborns under 37 weeks of gestation and the controls were newborns over 37 weeks. The data came from the records of 19,457 births in the city of Porto Alegre in the year 2012 from the Information System on Live Births of the Municipal Health Department. The analysis was carried outand adjusted by a Logistic Regression according to a hierarchical model. The variables studied were allocated into three hierarchy levels: sociodemographic variables; reproductive history; and gestational and birth factors. There were 767 cases allocated and 1,534 controls in a design of a case for two controls (1:2) by simple randomization. In the final model, a statistically significant association was found for prematurity for the following variables: mother's age under 19 years old (OR=1.32; CI 95%: 1.02-1.71) or over 34 years old (OR=1.39; CI 95%: 1.12-1.72); inadequate maternal schooling for age (OR=2.11; CI 95%: 1.22-3.65); multiple pregnancies (OR=1.14; CI 95%: 1.01-1.29); C-section (OR=1.15; CI 95%: 1.03-1.29); birth weights under 2,500g (OR=4.04; CI 95%: 3.64-4.49); Apgar score at five minutes between zero and three (OR=1.47; CI 95%: 1.12-1.91); and inadequate prenatal care (OR=1.18; CI 95%: 1.02-1.36). The present study showed the most immediate consequence of prematurity for newborns by evidencing its association with worse Apgar scores and low birth weight. The following factors were also shown as possible more distal determinants of prematurity: mother's age; inadequate maternal education; multiple gestation; inadequate prenatal care; and C-section.

    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.

    To determine whether infants exposed in utero to serotonin reuptake inhibitor (SRI) antidepressants or a DSM-IV-TR-defined mood disorder have significantly more neonatal discontinuation signs compared to an unexposed group of infants at 2-4 weeks after birth. This secondary analysis was derived from 2 observational studies with enrollment from July 2000 to December 2011 in Cleveland, Ohio, and Pittsburgh, Pennsylvania. Mothers (n = 214) belonged to one of 3 groups based on exposure status during pregnancy: (1) Comparison-women who did not take psychotropics during pregnancy and had no major mood disorder; (2) SRI-exposed-women with a mood disorder who were taking an SRI but no benzodiazepines; and (3) Mood Disorder-women with depression or bipolar disorder who did not take psychotropic medications. The infants were examined for signs according to the Finnegan Scale by evaluators blind to maternal exposure status. The rates of sign presence (defined as a score ≥ 2 on the Finnegan Scale) in the SRI, Mood Disorder, and Comparison groups were similar at 34.1%, 35.1%, and 30.4%, respectively. Women in the SRI group had a significantly higher preterm birth rate (24.4%) compared to the other 2 groups (7.4% and 8.9% in the Mood Disorder and Comparison groups, respectively; P = .012). Preterm newborns had a significantly higher sign rate compared to full-term newborns (54% vs 31%, P = .020). We observed a significant relationship between Finnegan signs and preterm birth. The presence of neonatal signs at 2-4 weeks was more closely associated with prematurity than with in utero SRI or mood disorder exposure.

    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.

  17. Therapeutic Hypothermia for Birth Asphyxia in Neonates.

    2017-03-01

    India contributes to the highest neonatal mortality globally. Birth asphyxia is one of the leading causes of neonatal mortality in India. A large number of neonates who suffer from birth asphyxia progress to Hypoxic Ischemic Encephalopathy (HIE). The risk of a neonate progressing to severe form of HIE is many times higher in the low and middle income countries (LMICs) with ill developed health infrastructure. Till date LMICs have had a low institutional delivery rate, poor regionalization of care, lack of adequate transport facilities and ill equipped neonatal intensive care facilities. This has lead to a tremendous burden on the health care systems with a cohort of developmentally challenged neonates surviving into adulthood. Recently, Therapeutic Hypothermia (TH) has emerged as an evidence based intervention to reduce mortality and neurodevelopmental disability associated with asphyxia induced encephalopathy. TH has become the gold standard in the management of such cases in the western world. Extension of this knowledge to the LMICs and countries like India require a better understanding of the unique sociocultural issues associated with asphyxial brain injury in neonates. The high incidence of sepsis and presence of economic constraints make this problem more complex in such countries. The current review has tried to address these issues and looked at the basics of this complex topic from the perspective of a general pediatrician.

  18. Dosing antibiotics in neonates: review of the pharmacokinetic data.

    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.

  19. Neonatal pneumonia in sub-Saharan Africa.

    2016-01-01

    Neonatal pneumonia is a devastating condition. Most deaths in sub-Saharan Africa can be attributed to preventable diseases, including pneumonia, diarrhoea and malaria, which together killed an estimated 2.2 million children under the age of 5 years in 2012, accounting for a third of all under-five deaths in this region. Some countries are making progress in reducing mortality through community-based health schemes; however, most countries in this region are far from achieving the World Health Organization Sustainable Development Goals for reducing childhood morbidity and mortality. The microorganisms causing neonatal pneumonia are well known. Both bacteria and viruses are commonly responsible, while fungal organisms occur in the context of nosocomial disease, and parasites occur in HIV-infected children. The common bacterial pathogens are group B streptococci (and other streptococcal species) and Gram-negative organisms, most notably Escherichia coli and Klebsiella spp. The viruses that predominate are the common respiratory pathogens, namely respiratory syncytial virus, human rhinovirus, and influenza virus. Viral disease is often nosocomial and transmitted to infected neonates in the neonatal intensive care unit or other neonatal facilities by infected parents and staff. Neonatal pneumonia often presents with non-specific respiratory distress in newborns. In the premature infant it is often indistinguishable from surfactant deficiency-associated respiratory distress syndrome. Therefore, diagnostic testing that is cheap and reliable is urgently sought in this region. All neonates with pneumonia must receive broad-spectrum antibiotic cover. This usually entails the combination of penicillin and an aminoglycoside. A lack of appropriate drugs and neonatal intensive care unit facilities are hampering progress in managing neonatal pneumonia.

    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. 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. 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). Infants receiving any postnatal care were significantly protected from neonatal death (OR = 0.63, p = 0.03). Public health interventions directed at reducing neonatal death should address community, household and individual level factors

    Neonatal and adult albumin was isolated by gel chromatography on Sephacryl S-300, from adult and umbilical cord serum, respectively. Binding of monoacetyl-diamino-diphenyl sulfone, warfarin, sulfamethizole, and diazepam was studied by means of equilibrium dialysis and the binding data were analyzed...... by the method of several acceptable fitted curves. It was found that the binding affinity to neonatal albumin is less than to adult albumin for monoacetyl-diamino-diphenyl sulfone and warfarin. Sulfamethizole binding to the neonatal protein is similarly reduced when more than one molecule of the drug is bound...

    2017-01-01

    Cerebral oxygenation is not always reflected by systemic arterial oxygenation. Therefore, regional cerebral oxygen saturation (rScO2) monitoring with near-infrared spectroscopy (NIRS) is of added value in neonatal intensive care. rScO2 represents oxygen supply to the brain, while cerebral fractional tissue oxygen extraction, which is the ratio between rScO2 and systemic arterial oxygen saturation, reflects cerebral oxygen utilization. The balance between oxygen supply and utilization provides insight in neonatal cerebral (patho-)physiology. This review highlights the potential and limitations of cerebral oxygenation monitoring with NIRS in the neonatal intensive care unit. PMID:28352624

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.

    Full Text Available Neonatal abstinence syndrome (NAS refers to the constellation of signs and symptoms exhibited by a newborn of drug-abusing mother. NAS is multisystemic disorder, most frequently involving central nervous and gastrointestinal systems with irritability, high-pitched cry, hyperactive reflexes, increased muscle tone, tremors, generalized convulsions, feeding and sleeping disorders, tachycardia, tachypnea, apnea, termolability and sweating, frequent hiccups, yawning and sneezing, vomiting, diarrhea and dehydration.Intrauterine narcotic disposition can give some other adverse effects beside NAS: fetal distress, premature birth, intrauterine growth retardation, microcephaly, increased incidence of congenital anomalies (cardiac and genitourinary anomalies, cleft palate, biliar atresia. Significantly increased risks of sudden infant’s death syndrome (SIDS, abnormalities in neurocognitive and behavioral development and deficiency in motor functions have also been noticed after the long-term surveys of these children.This paper is a case report of a newborn with developed clinical signs of NAS, but it also discusses diagnostics and management of such cases

At necropsy, all tissues were discolored various shades of yellow. Microscopically, there was degeneration and necrosis of cerebral neurons and cerebellar Purkinje cells; severe hepatocellular degeneration and necrosis; and deposition of amorphous golden-yellow material in the cerebellar granular cell layer, pulmonary alveoli, renal tubular epithelium, splenic trabecula, and the lamina propria of the small and large intestine. The golden-yellow material in the brain, lung, spleen, and small intestine was identified as bilirubin by histochemistry. Based on the macroscopic and microscopic findings, a diagnosis of kernicterus (bilirubin encephalopathy) was made. This report describes a rare case of equine neonatal kernicterus.

    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.

    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)

    2016-01-01

    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.

    Pneumonia is an important cause of neonatal infection and accounts for significant morbidity and mortality in the neonatal period. The best way to reduce the high prevalence of pneumonia at this age group is through identification and elimination of its risk factors. This case-control study was conducted in the department of Pediatrics, Dhaka Medical College & Hospital during Nov 2007 to Nov 2008 with an aim to identify the risk factors of pneumonia. Data were collected from 100 neonates, 50 cases and 50 controls who met the predefined inclusion criteria. Results shows mean birth weight (pneonatal resuscitation (ppneumonia. Multivariate analysis showed inadequate antenatal care (OR 168.9), home delivery (OR 13.8), intrapartum fever (OR 225.9), obstetric problem of mother (OR 33.4), requirement of resuscitation (OR 12.5), prolonged labour (OR 15.2) as significant risk factors of neonatal pneumonia.

    The objective of this study is to describe the usefulness of topiramate in refractory neonatal seizures. We reported the clinical off-label use of topiramate in three cases of refractory neonatal seizures of unclear origin with no response to conventional antiepileptic drugs. In all cases, the seizures were completely controlled with adding topiramate. All patients became seizure free during hospitalization and were followed by approximately 1 year after hospital discharge, with monotherapy with topiramate. The clinical off-label use of topiramate in neonatal seizures is still incipient. When searching publications in this matter, only one report was identified. Because of its efficacy for both seizures and neuroprotection, topiramate could be a useful choice in refractory neonatal seizures.

    Abstract Patterns of fetal growth predict non-communicable disease risk in adult life, but fetal growth variability appears to have a relatively weak association with maternal nutritional dynamics during pregnancy. This challenges the interpretation of fetal growth variability as ‘adaptation’. We hypothesized that associations of maternal size and nutritional status with neonatal size are mediated by the dimensions of the maternal pelvis. We analysed data on maternal height, body mass index (BMI) and pelvic dimensions (conjugate, inter-spinous and inter-cristal diameters) and neonatal gestational age, weight, length, thorax girth and head girth (n = 224). Multiple regression analysis was used to identify independent maternal predictors of neonatal size, and the mediating role of neonatal head girth in these associations. Pelvic dimensions displaced maternal BMI as a predictor of birth weight, explaining 11.6% of the variance. Maternal conjugate and inter-spinous diameters predicted neonatal length, thorax girth and head girth, whereas inter-cristal diameter only predicted neonatal length. Associations of pelvic dimensions with birth length, but not birth weight, were mediated by neonatal head girth. Pelvic dimensions predicted neonatal size better than maternal BMI, and these associations were mostly independent of maternal height. Sensitivity of fetal growth to pelvic dimensions reduces the risk of cephalo-pelvic disproportion, potentially a strong selective pressure during secular trends in height. Selection on fetal adaptation to relatively inflexible components of maternal phenotype, rather than directly to external ecological conditions, may help explain high levels of growth plasticity during late fetal life and early infancy.

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 Background An estimated 6 of 1,000 children with live births suffer from permanent hearing loss at birth or the neonatal period. At least 90% of cases occur in developing countries. Hearing loss should be diagnosed as early as possible so that intervention can be done before the age of 6 months. Objective To determine risk factors for hearing loss in neonates. 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.

    Marijuana use is becoming increasingly common in the obstetric population; however, it is unknown whether it is associated with poor neonatal outcomes. We sought to determine the prevalence and risk factors for marijuana use in pregnancy and to evaluate whether marijuana use is independently associated with poor neonatal outcomes. This was a retrospective cohort study of all consecutive, nonanomalous, term deliveries at 1 institution over a 4-year study period. Women with marijuana use during pregnancy, either by self-report or positive urine drug screen, were compared with women who did not use marijuana. The primary outcome was a composite neonatal morbidity including birthweight less than 2500 g, neonatal intensive care unit admission, 5-minute Apgar score less than 7, and umbilical artery pH less than 7.10. Univariate, bivariate, and multiple logistic regression analyses were performed. Among the 8138 women in the cohort, 680 (8.4%) used marijuana during pregnancy. Women who used marijuana were younger; more likely to be of African American race; have inadequate prenatal care; and use tobacco, alcohol, and other drugs. Medical comorbidities did not differ between groups. After adjusting for smoking, other drug use, and African American race, the composite and all individual markers of poor neonatal outcome were not significantly higher among women who used marijuana during pregnancy. Marijuana use is common in pregnancy but may not be an independent risk factor for poor neonatal outcomes in term pregnancies. Copyright © 2015 Elsevier Inc. All rights reserved.

    The potential for necrotizing enterocolitis (NEC) in neonates requiring cardiac surgery has contributed largely to wide feeding practice variations and a hesitation to initiate enteral feeding during the preoperative period, specifically those patients with hypoplastic left heart syndrome. A retrospective chart review of neonates undergoing cardiac surgery at a single institution between July 2011 and July 2013 was performed. The primary objective of this study was to determine if preoperative feeding was associated with NEC in neonates requiring cardiac surgery. Univariable and multivariable analyses were performed to evaluate the relationship between preoperative feeding and NEC. Secondary outcomes including growth failure, total ventilator days, total length of stay, and tube-assisted feeds at discharge were analyzed. One hundred thirty consecutive neonates who required cardiac surgery were included in the analysis. Preoperative feeding occurred in 61% (n = 79). The overall prevalence of NEC was 9% (12/130), including three neonates with surgical NEC. There was no difference in the prevalence of NEC between the preoperative feeding and nil per os (NPO) groups. Preoperative NPO status was associated with longer ventilator-dependent days ( P = .01) but was not associated with worsened growth failure, longer length of stay, or increased prevalence of tube-assisted feeds at discharge. In this study cohort, preoperative feeding was associated with a low prevalence of NEC. Larger prospective studies evaluating the safety and benefits of preoperative feeding in cardiac neonates are warranted.

    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 shoulder 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.

    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.

    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. Only in oliguric neonates with severe perinatal asphyxia (31 % the outcome was

    Full Text Available Neonatal septicemia is the most important cause of neonatal mortality. A wide variety of bacteria both aerobic and anaerobic can cause neonatal sepsis. Genus Pantoea is a member of Enterobacteriaceae family that inhabits plants, soil and water and rarely causes human infections, however, Pantoea dispersa has not been reported as a causative organism for neonatal sepsis. We hereby report two neonates with early onset sepsis caused by Pantoea dispersa. Early detection and appropriate antibiotic therapy can improve overall outcome of this rare infection in neonates.

    Full Text Available Background: Hypothermia is very prevalent in neonatal transport and can increase morbidity and mortality in this age group. Materials and Methods: In this study, all neonates transported from different parts of Bushehr province to Ali Asghar hospital during the second half (2007 were checked for axillary temperature on admission. Results: 328 neonates were entered to the study. The incidence of hypothermia was 47.6 percent. There was a significant relationship between hypothermia and transfer method (with or without incubator, gestational age, chronological age on admission, birth weight, Apgar score (P<0.0001 and neonatal outcome (P=0.001. Conclusion: Hypothermia leads to increased mortality in neonates and is related to prematurity and low birth weight and low Apgar score. Kangaroo mother care (KMC is recommended instead of incubator care to prevent hypothermia during transfer.

    Full Text Available BACKGROUND: The capacity to memorize speech sounds is crucial for language acquisition. Newborn human infants can discriminate phonetic contrasts and extract rhythm, prosodic information, and simple regularities from speech. Yet, there is scarce evidence that infants can recognize common words from the surrounding language before four months of age. METHODOLOGY/PRINCIPAL FINDINGS: We studied one hundred and twelve 1-5 day-old infants, using functional near-infrared spectroscopy (fNIRS. We found that newborns tested with a novel bisyllabic word show greater hemodynamic brain response than newborns tested with a familiar bisyllabic word. We showed that newborns recognize the familiar word after two minutes of silence or after hearing music, but not after hearing a different word. CONCLUSIONS/SIGNIFICANCE: The data show that retroactive interference is an important cause of forgetting in the early stages of language acquisition. Moreover, because neonates forget words in the presence of some--but not all--sounds, the results indicate that the interference phenomenon that causes forgetting is selective.

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.

    Endocrine disruptors are substances commonly encountered in every setting and condition in the modern world. It is virtually impossible to avoid the contact with these chemical compounds in our daily life. Molecules defined as endocrine disruptors constitute an extremely heterogeneous group and include synthetic chemicals used as industrial solvents/lubricants and their by-products. Natural chemicals found in human and animal food (phytoestrogens) also act as endocrine disruptors. Different from adults, children are not exposed only to chemical toxins in the environment but may also be exposed during their intrauterine life. Hundreds of toxic substances, which include neuro-immune and endocrine toxic chemical components that may influence the critical steps of hormonal, neurological and immunological development, may affect the fetus via the placental cord and these substances may be excreted in the meconium. Children and especially newborns are more sensitive to environmental toxins compared to adults. Metabolic pathways are immature, especially in the first months of life. The ability of the newborn to metabolize, detoxify and eliminate many toxins is different from that of the adults. Although exposures occur during fetal or neonatal period, their effects may sometimes be observed in later years. Further studies are needed to clarify the effects of these substances on the endocrine system and to provide evidence for preventive measures.

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

    Pain from skin penetrating procedures (procedural pain) during infancy in the neonatal intensive care unit (NICU) may result in changes of nociceptive sensitivity in later life. This supports the need for pain management during such vulnerable periods in life. This study, therefore, analyses the short- and long-term consequences of neonatal paracetamol (acetaminophen) treatment on pain behaviour in an experimental rat model of neonatal procedural pain. A repetitive needle-prick model was used, in which neonatal rats received four needle pricks into the left hind paw per day from postnatal day 0 to day 7 (P0-P7). Paracetamol (50 mg/kg/day s.c.) was administered daily (P0-P7), and sensitivity to mechanical stimuli was compared with a needle-prick/saline-treated group and to a tactile control group. At 8 weeks of age, all animals underwent an ipsilateral paw-incision, modelling postoperative pain, and the duration of hypersensitivity was assessed. Neonatal paracetamol administration had no effect upon short-term mechanical hypersensitivity during the first postnatal week or upon long-term baseline sensitivity from 3 to 8 weeks. However, neonatal paracetamol administration significantly reduced the postoperative mechanical hypersensitivity in young adults, caused by repetitive needle pricking. Paracetamol administration during neonatal procedural pain does not alter short-term or long-term effects on mechanical sensitivity, but does reduce the duration of increased postoperative mechanical hypersensitivity in a clinically relevant neonatal procedural pain model. Paracetamol can be used safely in neonatal rats. Neonatal paracetamol treatment had no effect upon short-term mechanical hypersensitivity during the first postnatal week, nor upon long-term baseline sensitivity from 3 to 8 weeks. Paracetamol treatment during the first postnatal week significantly reduced the postoperative mechanical hypersensitivity in young adult rats. © 2016 European Pain Federation

    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.

    Neonatal arrhythmias (NAs) are defined as abnormal heart rates in the neonatal period. They may occur as a result of various cardiovascular, systemic and metabolic problems. A retrospective chart review was performed on newborns who were diagnosed with NA during hospitalization in a neonatal intensive care unit (NICU), or who were admitted to the NICU because of an arrhythmia diagnosis in two NICUs in Turkey from May 2011 to June 2013. Seventeen neonates with arrhythmias were identified. The incidence of NA was 0.4% and 0.3% in the two NICUs, and was 0.37% in the study population as a whole. Mean gestational age was 37 (29-40) weeks. Nine of the infants (53%) were diagnosed with fetal arrhythmia (FA) during the last week of gestation. The distribution of NA types was as follows: six (35%) supraventricular tachycardia (SVT), six (35%) premature atrial contractions (PACs), two (11%) premature ventricular contractions (PVCs), two (11%) multiple arrhythmias such as SVT + PAC and AV block + PVC, and one (5%) AV block. Wolff-Parkinson-White syndrome was present in one patient. An association of NA with congenital heart malformations was identified in five cases. Cardiac arrhythmias are important causes of infant morbidity, and an occasional cause of infant mortality if undiagnosed and untreated. It is important for the physician to be aware of the etiology, development and natural history of arrhythmias in the fetal and neonatal period.

    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.

    Full Text Available Background Supraventricular Tachycardia (SVT is the most frequent arrhythmia requiring a medical treatment in neonates. Objectives The aim of our study was to evaluate and manage neonatal supraventricular tachycardia. Methods This study was performed on 22 newborns that were diagnosed with SVT at two neonatal intensive care units (NICU in south west of Iran from October 2012 to October 2015. Data on gender, age, weight, maternal age, gestational age, presence of congenital heart disease, blood pressure in admission, duration of hospitalization period, duration of SVT, medicine for the control of SVT, list of medicine administered at releasing time were collected. Echocardiography was performed for all patients. Data was analyzed by the SPSS version 18 software. Results Twelve neonates were male (54.5% and ten (45.5% were female. The mean age was 11.68 ± 8.17 days. Three neonates (13.6% had congenital heart disease. The mean duration of hospitalization was 6.54 ± 3.98 days. Nine patients (41% only had responded adenosine. One patient had hypotensive that received D/C shock. Conclusions We concluded that in most SVT patients, conventional treatment can be helpful and an only minor percentage of patients need to receive flecainide as the last line of treatment.

    The human connectome is the result of an elaborate developmental trajectory. Acquiring diffusion-weighted imaging and resting-state fMRI, we studied connectome formation during the preterm phase of macroscopic connectome genesis. In total, 27 neonates were scanned at week 30 and/or week 40 gestational age (GA). Examining the architecture of the neonatal anatomical brain network revealed a clear presence of a small-world modular organization before term birth. Analysis of neonatal functional connectivity (FC) showed the early formation of resting-state networks, suggesting that functional networks are present in the preterm brain, albeit being in an immature state. Moreover, structural and FC patterns of the neonatal brain network showed strong overlap with connectome architecture of the adult brain (85 and 81%, respectively). Analysis of brain development between week 30 and week 40 GA revealed clear developmental effects in neonatal connectome architecture, including a significant increase in white matter microstructure (P development. © The Author 2014.

    A random sample of 457 neonates was prospectively studied in order to identify the incidence, common types, and risk factors for arrhythmias in the neonatal intensive care unit (NICU). A 12-lead EKG was studied in all neonates (n = 457). A total of 139 Holter studies was done in every fourth baby with a normal EKG (n = 100) and in all babies with an abnormal EKG (n = 39). Of the 100 infants who were thought to be arrhythmia-free by EKG, nine infants demonstrated an arrhythmia on Holter studies. When we correlated screening results with maternal, obstetrical, and neonatal risk factors; arrhythmias were significantly associated with male gender, more mature gestational age, lower glucose levels, maternal smoking, high umbilical artery lines, and the use of the nebulized beta-2 adrenergic treatment, whereas umbilical venous lines and dopamine infusion did not relate to arrhythmia. We conclude that arrhythmias are more common in the NICU than in the general neonatal population. Compared to Holter monitoring, the sensitivity of the EKG was only 89%.

    The longterm prognosis of neonatal septicemia during the first four weeks of life has been estimated. Of 90 infants with the diagnosis of neonatal septicemia during a five-year period, 1969--1973, 65 infants survived the initial treatment. Another two infants died with complications of their main disease, intestinal atresia, at the age of two months. Thus the total mortality in neonatal septicemia in this series was 30%. The remaining 63 children have been investigated between ages of 2 1/2 and 6 1/2 years. Of these 63 children we have found 14 children (22% of the surviving) with handicaps where the septicemia can be regarded as a possible cause of the handicap. Of these 14 children only six had an "uncomplicated" septicemia while four of them had meningitis and four had osteomyelitis. Furthermore, of the 14 handicapped children nine were delivered preterm (28--36 weeks) and all of them had one or more additional neonatal diagnoses than septicemia. The prognosis, both immediate and longterm, of neonatal septicemia in the present series compares favourably to most international studies. The importance of early detection together with an aggresive treatment of the septicemia is stressed and is considered as the main reason for the good prognosis.

    Circumcision is the most common surgical procedure performed in the neonatal period in North America. If untreated, the pain of circumcision causes both short and long term changes in infant behaviours. The most widely studied pharmacological intervention for pain management during circumcision is dorsal penile nerve block (DPNB) by injected lidocaine (lignocaine). Randomised controlled trials have demonstrated its efficacy; infants premedicated with lidocaine have significantly smaller changes in physiological and pain-related behaviours compared with infants who are not given analgesics. A meta-analysis of injection-related adverse effects (bruising/haematoma) yielded a risk of 6.7% (95% confidence interval, 0.5 to 12.9%). Systemic toxicity from injected local anaesthesia has not been reported. Less effective modalities include topical anaesthesia with lidocaine-prilocaine cream [Eutectic Mixture of Local Anaesthetics (EMLA)], lidocaine cream and oral administration of sucrose. The good tolerability of lidocaine-prilocaine cream has been demonstrated by a lack of clinically significant methaemoglobinaemia when used appropriately. Nonpharmacological interventions (pacifier, specially designed restraint chair) reduce distress during the procedure, and paracetamol (acetaminophen) may provide postoperative analgesia. No single agent has been demonstrated to ameliorate pain for all infants undergoing circumcision. A multimodal approach of pharmacotherapy is currently recommended. Studies evaluating the efficacy of combined analgesia have demonstrated significant benefits for combinations of 2 or more forms of treatment (such as DPNB and sucrose-dipped pacifier) compared with single interventions. The instrument used to perform the circumcision is also important. The Mogen clamp has been shown to be associated with a shorter procedure time and less pain compared with the Gomco clamp. If circumcision is to be performed on infants, it is, therefore, recommended that

    Sensorial saturation (SS) is a procedure in which touch, massage, taste, voice, smell, and sight compete with pain, producing almost complete analgesia during heel prick in neonates. SS is an apparently complex maneuvre, but when correctly explained it is easily learnt. In the present paper, we studied its feasibility, assessing whether a long training is really needed to achieve good results. We enrolled 66 consecutive babies and divided them randomly into 3 groups which received the following forms of analgesia: glucose plus sucking (A), SS performed by nurses (B), SS performed by mothers (C). We did not use perfume on the caregivers' hands, so that babies could smell the natural scent of the hands. We assessed pain level by the ABC scale. Median scores of groups A, B, and C were: 1 (0 to 6), 0 (0 to 4), and 0 (0 to 6), respectively. Mean scores were: 0.6, 0.6, and 1.7 and standard errors were 0.38, 0.22, and 0.32, respectively. Scores of groups B and C were significantly lower than that of A (P=0.03 and 0.006, respectively). No significant difference was found between values of scores of groups B and C. Even without the use of perfume on the hands, SS was effective as an analgesic maneuvre. It made no difference whether SS was performed by mothers who applied it for the first time or experienced nurses. SS is rapid to learn and any caregiver (mother, pediatrician or nurse) can effectively use it.

    Perinatal as well as neonatal mortality record in our country is one of the highest in the world. Home deliveries, lack of adequate facilities, poverty and lack of education are sonme of the important known causes. The present study was planned to determine neonatal mortality in Hazara. Hospital records of neonatal admissions at Ayub Teaching Hospital (ATH) Abbottabad from 1st January 2007-31st December 2007 were analysed retrospectively. Percent neonatal mortality was calculated from the record, along with the causes of neonatal mortality. A total of 1705 neonates were admitted in the study period at the department of neonatology Ayub Teaching Hospital Abbottabad. Out of 1,705 neonates 947 (56%) were males while 857 (44%) were females with a male to female ratio of 1.24:1 . Majority, 1,411 out of 1,705 (83%), of the neonates was admitted during the 1st week of their life, mean age 6 days. Asphyxia, sepsis and prematurity were the three most common causes of neonatal admissions contributing 27%, 26% and 24% respectively. Overall mortality was 11%. Neonatal mortality is an important contributing factor to infant mortality in Hazara Division. Majority of patients was admitted in the first week of life which indicates that good antenatal and natal care can reduce the mortality and morbidity of our neonates. Improvement in the prenatal, natal and nursery care as a whole can reduce the neonatal mortality in preterm as well as full term neonates.

    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

    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.

    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...

    The authors report their experience with the routinary use of a computerized digital radiography system in Intensive Neonatal Care department. The conventional screen-film system is replaced by photostimulable imaging plates, which are scanned during processing by a laser providing the digital image. The latter is subsequently processable on high-resolution monitors. Over a 6-month period 86 examinations were performed with this method in Intensive Neonatal Care; good technical results were obtained. The use of digital radiography in intensive neonatal care is extremely promising for it allows high-quality images to be obtained, and radiation dose and number of acquisitions to be reduced. Finally, work stations allow both selective visualization of different body structures and their magnification

    Neonatal and adult albumin was isolated by gel chromatography on Sephacryl S-300, from adult and umbilical cord serum, respectively. Binding of monoacetyl-diamino-diphenyl sulfone, warfarin, sulfamethizole, and diazepam was studied by means of equilibrium dialysis and the binding data were analyzed...... by the method of several acceptable fitted curves. It was found that the binding affinity to neonatal albumin is less than to adult albumin for monoacetyl-diamino-diphenyl sulfone and warfarin. Sulfamethizole binding to the neonatal protein is similarly reduced when more than one molecule of the drug is bound...... per albumin molecule, and binding of the first sulfamethizole molecule is possibly reduced as well. Diazepam binds with equal affinity to the fetal and adult proteins. Among the two main albumin drug-binding functions, for warfarin and diazepam, the former is thus compromised in the newborn infant...

  19. Endocardial Pacemaker Implantation in Neonates and Infants

    Directory of Open Access Journals (Sweden)

    2006-04-01

    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.

    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.

    Full Text Available Neonatal listeriosis is widely reported, but this is the first case reported in Serbia. A newborn developed respiratory distress syndrome 2 hours after delivery and was admitted to the neonatal intensive care unit. Initial empirical therapy was inappropriate. Consequently, on the second day, the patient developed meningitis. Listeria monocytogenes was isolated from the tracheal aspirate, blood, periumbilical swab, and cerebrospinal fluid. After bacteriology results, the therapy was changed to ampicillin and meropenem. On day 11 of hospitalization, the patient developed nosocomial infection due to multidrug-resistant Stenotrophomonas maltophilia. Since therapeutic options were limited, the patient was treated with ciprofloxacin. After 26 days of hospitalization the patient showed complete recovery and was discharged with no apparent sequelae. This case showed the importance of bacteriological examination in cases of infections caused by uncommon organisms. Pediatricians should be aware of the neonatal infection caused by Stenotrophomonas maltophilia.

    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.

    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 mortality rate remains high in Brazil. The aim of the study was to evaluate the factors associated with hospitalization during the neonatal period. Cross-sectional study conducted in ten randomly-selected Brazilian municipalities. Mothers of children under the age of 6 who were carrying the child's health booklet were interviewed in basic health units. Hierarchical modeling of sociodemographic factors (distal level), maternal variables (intermediate level), and features of the newborns (proximal level) was performed. The variables that presented a value of p≤0.20 in the univariate analysis were included in the multivariate hierarchical modeling process, with block input according to their hierarchical level. The variables with a value of p≤0.05 were considered statistically significant. 2022 mothers were included, allowing 258 (12.8%) cases of hospitalization during the neonatal period to be identified, of which 49.7% were male, 8.9% were premature, and 8.4% had low birth weight (<2500g). After analysis by hierarchical approach, factors associated with neonatal hospitalization (prevalence ratio [95% CI]) included: history of prematurity (2.03 [1.25-3.30], p=0.004), gestational risk (2.02 [1.46-2.79], p<0.001); intrapartum risk (3.73 [2.33-5.99], p<0.001); gestational age (32-37 weeks: 13.83 [1.74-110.09], p=0.01; and<32 weeks: 25.03 [3.03-207.12], p=0.003); low birth weight (3.95 [2.56-6.09], p<0.001), and male gender (1.44 [1.09-1.98], p=0.01). Factors associated with maternal and neonatal history are associated with neonatal hospitalization. Copyright © 2017 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

    2002-01-01

    Gardnerella vaginalis is a normal component of the human vaginal flora and commonly associated with bacterial vaginosis. Invasive infection in obstetrical patients due to G. vaginalis has also been reported. In the pediatric age range, infection due to G. vaginalis is extremely rare and limited to neonates. We describe a 23-week premature infant with G. vaginalis bacteremia and review the characteristics of neonatal G. vaginalis infection reported in the literature. Antibiotic susceptibility testing of G. vaginalis isolates has shown that penicillin, ampicillin, erthromycin, clindamycin, and vancomycin are effective in vitro.

    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.

  13. A case report of neonatal scabies

    2017-01-01

    Full Text Available Scabies is commonly seen worldwide, in its usual classic form when afflicting older children and adults. However, neonatal scabies is described as its own entity in the literature. We present a case of a 4-week old infant with a generalized papulopustular, vesicular, and crusted rash who was diagnosed with scabies. We contrast the differing clinical features of neonatal and classic scabies, describe possible mimickers of this diagnostic dilemma, and review current treatment options available for scabies in this very young age group.

    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.

    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.).

    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.

    1986-01-01

    The authors reviewed the radiographic findings in 40 neonates and 90 children and adolescents with hypertension. 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

    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

    2011-05-01

    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.

    2015-12-01

    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.

    2015-10-01

    Full Text Available BACKGROUND: Cardio vascular malformations are the most common congenital malformations. Early recognition of congenital heart disease is important in the neonatal period, as many of them may be fatal if undiagnosed. AIM : To study the epidemiology of neonatal cardiac murmurs. To identify clinical characteristics which differentiates pathological murmur from functional murmurs to assess the reliability of clinical evaluation in diagnosing congenital heart diseas e? METHODS : The study population included all neonates admitted in a Hospital in Visakhapatnam to the NICU, postnatal ward, attending pediatric OPD and were detected to have cardiac murmurs. It was a cross sectional study over a period of 16 months. A clinical diagnosis was made based on history and clinical examination. Then Chest X ray and ECG were done in symptomatic infants. Echo cardiography was done in all neonates for confirmation of diagnosis, the neonates were again examined daily till they were in hospital and during the follow up visit at 6 weeks. RESULTS : A total of 61 neonates were included and was conducted over a period of 16 months . T he incidence of cardiac murmurs among intramural neonates was 13.5 for 1000 live births. Most frequent symptom was fast breathing in 10[16.4%] cases. VSD was the most common diagnosis clinically in 19[31.47%] babies. The most frequent diagnosis was acyanotic complex congenital heart disease, Only intra mural neonates were considered for the incidence of murmurs and the incidence of cardiac murmurs among them babies was 13.5 for 1000 live in 23[37.7%] cases followed by 10[16.4%] cases each of VSD and ASD respectively. Overall in our study 73.77% [45 cases] of the murmurs were diagnosed correctly and confirmed by Echocardiography. INTERPRETATIONS & CONCLUSIONS: 1. It is possible to make clinical diagnosis in many cases of congenital heart diseases. 2. The functional murmurs could be differentiated from those arising from structural heart

Foram construídos mapas temáticos e usadas técnicas para apreciação formal de dependência espacial. Mediante modelos de regressão linear múltipla (espacial e não espacial verificou-se a relação entre distribuição espacial dessa mortalidade e fatores selecionados. Evidenciou-se autocorrelação espacial para a mortalidade neonatal (I = 0,17; p = 0,0100, não havendo, portanto, aleatoriedade em sua distribuição. Foi delineado um padrão espacial em que os maiores riscos (> 9,0/1.000 nascidos vivos concentraram-se em áreas do centro e subúrbio, onde reside a população de menor condição socioeconômica, mostrando-se esta distribuição associada aos fatores de risco analisados. A proporção de nascidos vivos com baixo peso foi a única variável significativamente associada à mortalidade neonatal. Possivelmente, as condições de vida da população contribuíram para a desigual distribuição espacial da mortalidade neonatal nesse município.An ecological study was performed to identify patterns in the spatial distribution of neonatal mortality and risk areas as well as associated factors in Salvador, Bahia State, Brazil, 2000-2006. A thematic map was constructed, and techniques were used for formal assessment of spatial dependence. No spatial and spatial regression models were used to assess possible relationships between selected factors and spatial distribution of neonatal mortality. Spatial autocorrelation was observed in neonatal mortality (I = 0.17; p = 0.0100, so its distribution was non-random. The analysis showed a spatial pattern in which the highest risk (> 9.0/1,000 live births was concentrated in the downtown areas and peripheral neighborhoods with the highest concentration of low-income families, and this was associated

    2016-03-15

    Even though Serratia marcescens is not one of the most common causes of infection in neonates, it is associated with grave morbidity and mortality. We describe the evolution of brain parenchymal affectation observed in association with S. marcescens infection in neonates. This retrospective case series details brain ultrasound findings of five neonates with hospital-acquired S. marcescens infection. Neonatal S. marcescens infection with or without associated meningitis can be complicated by brain parenchymal affectation, leading to cerebral abscess formation. It is recommended that all neonates with this infection should undergo neuro-imaging more than once before discharge from hospital; this can be achieved using bedside ultrasonography.

    Advantages of caffeine for apnea of prematurity have prompted clinicians to use it prophylactically even before apnea. To determine the effect of early initiation of caffeine therapy on neonatal outcomes in very preterm infants born in Canada. A retrospective cohort study was conducted. Patients included preterm neonates born at less than 31 weeks' gestation admitted to 29 participating Canadian Neonatal Network neonatal intensive care units between January 1, 2010, and December 31, 2012. Neonates who received caffeine were divided into 2 groups based on the following timing of caffeine initiation: within the first 2 days after birth (early) and on or after the third day following birth (late). A composite of death or bronchopulmonary dysplasia. Of 5517 eligible neonates, 5101 (92.5%) received caffeine (early: 3806 [74.6%]; late: 1295 [25.4%]). There was no difference in weight or gestational age at birth between the groups. Neonates in the early group had decreased odds of a composite outcome of death or bronchopulmonary dysplasia (adjusted odds ratio [AOR], 0.81; 95% CI, 0.67-0.98) and patent ductus arteriosus (AOR, 0.74; 95% CI, 0.62-0.89). There was no difference between the groups in mortality (AOR, 0.98; 95% CI, 0.70-1.37), necrotizing enterocolitis (AOR, 0.88; 95% CI, 0.65-1.20), severe neurological injury (AOR, 0.80; 95% CI, 0.63-1.01), or severe retinopathy of prematurity (AOR, 0.78; 95% CI, 0.56-1.10). In very preterm neonates, early (prophylactic) caffeine use was associated with a reduction in the rates of death or bronchopulmonary dysplasia and patent ductus arteriosus. No adverse impact on any other outcomes was observed.

    2014-01-01

    Clinical handover ensures continuity of care, providing the opportunity to transfer responsibility and accountability for the care of a patient from nurse to nurse. The aim of this study was to examine afternoon nursing clinical handover from the perspective of nurses, exploring the quality of information, the interactions and support, the efficiency and the involvement of parents in a private neonatal unit. An exploratory, descriptive, prospective quantitative survey with qualitative elements was undertaken using The Handover Evaluation Scale (O'Connell, MacDonald, & Kelly, 2008). All nurses working in the Neonatal unit who attend afternoon handover, were invited to participate in the study (N = 22), with N = 16 responses received. The quantitative and qualitative results indicate that the quality of the information handed over in neonatal care units can be maintained despite intrinsic limitations. Additionally, high levels of support and interaction between nursing staff in this stressful practice environment occur during the handover period. Given the vulnerability of neonates it is important that accurate information is efficiently handed over. In order to do this distractions should be minimised. Finally, parental involvement in handover should be actively encouraged whenever feasible.

    In the first days of life, the daily evaporative loss from premature neonates can reach up to 20% of body mass. Such loss can be reduced by increasing the air humidity inside the incubator. Neither passive humidification nor open loop systems allow high humidity rates to be maintained or easily controlled: at 34 degrees C, the maximum levels vary with the system from 40% to 77% of relative humidity. The skin evaporative exchanges between the neonate and the environment are directly proportional to the water vapour partial pressure difference between the neonate's skin and the air. An active closed loop system has been designed, which permits reliable and accurate control of humidity according to the water vapour partial pressure set, between 1 and 6 kPa, in an air temperature range of 28-39 degrees C. It is characterised by variations of about 0.05 kPa around the set value and a maximum humidification speed of 0.25 kPa min-1. The algorithm is based on optimal control and the dynamic programming principles. Test results place this active system above usual systems for its power, precision and adaptability. It is an exploitable tool in fundamental and clinical research, to precisely study the humidity effects on neonatal comfort and thermo-regulation evolution.

    Heitzler, Ella T

    To measure the cultural competence level of obstetric and neonatal nurses, explore relationships among cultural competence and selected sociodemographic variables, and identify factors related to cultural competence. Descriptive correlational study. Online survey. A convenience sample of 132 obstetric and neonatal registered nurses practicing in the United States. Nurse participants completed the Cultural Competence Assessment (CCA) instrument, which included Cultural Awareness and Sensitivity (CAS) and Cultural Competence Behaviors (CCB) subscales, and a sociodemographic questionnaire. Correlation and regression analyses were conducted. The average CCA score was 5.38 (possible range = 1.00-7.00). CCA scores were negatively correlated with age and positively correlated with self-ranked cultural competence, years of nursing experience, years of experience within the specialty area, and number of types of previous cultural diversity training. CCB subscale scores were correlated positively with age, years of nursing experience, years of experience within the specialty area, and number of types of previous diversity training. CAS subscale scores were positively correlated with number of types of previous diversity training. Standard multiple linear regression explained approximately 10%, 12%, and 11% of the variance in CCA, CAS, and CCB scores, respectively. Obstetric and neonatal registered nurses should continue to work toward greater cultural competence. Exposing nurses to more types of cultural diversity training may help achieve greater cultural competence. Copyright © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    To develop a neonatal MR-compatible incubator for transporting babies between a neonatal intensive care unit and an MRI unit that is within the same hospital but geographically separate. The system was strapped to a standard MR-compatible patient trolley, which provides space for resuscitation outside the incubator. A constant-temperature exothermic heat pad was used to maintain temperature together with a logging fluoro-optic temperature monitor and alarm system. The system has been designed to accommodate standard knee-sized coils from the major MR manufacturers. The original incubator was constructed from carbon fibre, but this required modification to prevent radiofrequency shading artefacts due to the conducting properties of the carbon fibre. A high-tensile polyester material was used, which combined light weight with high impact strength. The system could be moved onto the patient bed with the coils and infant in place by one technologist. Studies in eight neonatal patients produced high quality 1.5 T MR images with low motion artefacts. The incubator should also be compatible with imaging in 3 T MR systems, although further work is required to establish this. Images were acquired using both rapid and high-resolution sequences, including three-dimensional volumes, proton spectra and diffusion weighting. The incubator provides a safe, quiet environment for neonates during transport and imaging, at low cost.

    2013-01-01

    Based on the observation that coagulation necrosis occurs in the majority of neonatal necrotizing enterocolitis (NEC) patients, it is clear that intestinal ischemia is a contributing factor to the pathogenesis of NEC. However, the published studies regarding the role of intestinal ischemia in NEC are controversial. The aim of this paper is to review the current studies regarding intestinal microcirculatory dysfunction and NEC, and try to elucidate the exact role of intestinal microcirculatory dysfunction in NEC. The studies cited in this review were mainly obtained from articles listed in Medline and PubMed. The search terms used were "intestinal microcirculatory dysfunction" and "neonatal necrotizing enterocolitis". Mainly original milestone articles and critical reviews written by major pioneer investigators in the field were selected. Immature regulatory control of mesentery circulation makes the neonatal intestinal microvasculature vulnerable. When neonates are subjected to stress, endothelial cell dysfunction occurs and results in vasoconstriction of arterioles, inflammatory cell infiltration and activation in venules, and endothelial barrier disruption in capillaries. The compromised vasculature increases circulation resistance and therefore decreases intestinal perfusion, and may eventually progress to intestinal necrosis. Intestinal ischemia plays an important role through the whole course of NEC. New therapeutic agents targeting intestinal ischemia, like HB-EGF, are promising therapeutic agents for the treatment of NEC.

    Summary Background To compare maternal and neonatal outcomes of term macrosomic and adequate for gestational age (AGA) pregnancies. Material/Methods A retrospective analysis was performed on all term singleton macrosomic (birth weight ≥4000 g) and AGA (birth weight >10th percentile and shoulder dystocia, neonatal hypoglycemia, and had longer hospitalization period (both in vaginal and cesarean deliveries). Specifically, the odds ratio (OR) relative to AGA pregnancies for each macrosomic category (4000–4250 g, 4250–4500 g and ≥4500 g) of shoulder dystocia was 2.37, 2.24, 7.61, respectively, and for neonatal hypoglycemia 4.24, 4.41, 4.15, respectively. The risk of post partum hemorrhage was statistically increased when birth weight was >4500 g (OR=5.23) but not for birth weight between 4000–4500 g. No differences were found in the rates of extensive perineal lacerations between AGA and the different macrosomic groups. Conclusions Macrosomia is associated with increased rate of cesarean section, shoulder dystocia, neonatal hypoglycemia, and longer hospitalization, but not associated with excessive perineal tears. Increased risk of PPH was found in the >4500g group. PMID:22936200

    We assessed whether the earlier described 'thin-fat phenotype' is present in Surinam South Asian babies of the fourth to fifth generation after migration from India. In this observational study we collected data from 39 South Asian term neonates and their mothers in Paramaribo, Surinam. We compared the following data with data from an earlier study in Southampton, UK (338 neonates) and in Pune, India (631 neonates): maternal body mass index, neonatal weight, length, head, mid-upper arm and abdominal circumferences and subscapular skinfold thickness. The mothers in Paramaribo were older than the Southampton mothers; their body mass index was comparable. Mean birth weight was 3159 g (Southampton: 3494 g; Pune: 2666 g). Compared with Southampton babies, the Paramaribo babies were smaller in nearly all body measurements, the smallest being abdominal circumference at the umbilicus level (s.d. score: -1.62; 95% confidence interval (CI): -2.07 to -1.16) and mid-upper arm circumference (s.d. score: -1.08; 95% CI: -1.46 to -0.69). In contrast, subscapular skinfold thickness was similar (s.d. score: +0.08; 95% CI: -0.24 to +0.55). Except for subscapular skinfold thickness and length, all neonatal measurements were intermediate between those from Southampton and Pune. The thin-fat phenotype is preserved in Surinam South Asian neonates of the fourth to fifth generation after migration from India.

    Full Text Available Background/Aim. Hemodynamic stress is the leading cause of acute renal failure (ARF in premature neonates. Incidence of ARF in this population is between 8 and 24%. The aim of this study was to determine the frequency of presence of ARF in premature neonates, as well as its impact on their survival. Methods. A retrospective study of 114 premature neonates [(gestational age, GA less than 37 gestation weeks (gw] admitted to the Intensive Care Unit (ICU at the Pediatric Clinic, Institute of Child and Youth Healthcare of Vojvodina in 2007 was conducted. Serum creatinine, urea and bilirubine were determined on the 3rd day of life in 65 newborns who met inclusion criteria. ARF was diagnosed in 16 newborns (n=16/65; 25%. Results. The premature neonates with ARF had significantly lower GA [<28 gw - 8/16 (50% vs. 5/49 (10%; p < 0.05], birth weight (BW (1 265 g vs. 1615 g; p < 0.05 and systolic blood pressure (43.37 mm Hg vs. 52.7 mmHg; p < 0.05 than ones without ARF. Non-olyguric ARF was diagnosed in 62% of newborns with ARF (n=10/16, while the rest had the olyguric type (n = 6/16; 38%. Twenty-five percent of premature neonates with ARF (n = 4/16 died in contrast to 10% of premature neonates without ARF (n = 5/49. ARF was treated conservatively in all but 3 cases when peritoneal dialysis was performed. Renal function has recovered completely in all of the survivors. In order to determine their predictivity in relation to ARF, following parameters were analyzed: GA, BW < 1 500 g, presence of concomitant sepsis and intracranial hemorrhage grade III/IV. BW < 1 500 g demonstrated the highest sensitivity (se 0.75, while GA < 28 gw, sepsis and intracranial hemorrhage grade III/IV showed high specificity (sp = 0.90, 0.89 0.88, respectively. Conclusion. Acute renal failure frequently occurs in population of premature neonates and requires meticulous fluid and electrolyte balance, especially in the case of low birth weight and extreme immaturity.

    Maternal depression and anxiety have been found to negatively affect fetal and neonatal growth. However, the independent effects of maternal depression and anxiety on fetal-neonatal growth outcomes and trajectories remain unclear. This study aimed to analyze simultaneously the effects of maternal prenatal depression and anxiety on (1) neonatal growth outcomes, and (2), on fetal-neonatal growth trajectories, from the 2nd trimester of pregnancy to childbirth. A sample of 172 women was recruited and completed self-reported measures of depression and anxiety during the 2nd and 3rd trimesters of pregnancy, and at childbirth. Fetal and neonatal biometrical data were collected from clinical reports at the same assessment moments. Neonates of prenatally anxious mothers showed lower weight (p=0.006), length (p=0.025), and ponderal index (p=0.049) at birth than neonates of prenatally non-anxious mothers. Moreover, fetuses-neonates of high-anxiety mothers showed a lower increase of weight from the 2nd trimester of pregnancy to childbirth than fetuses-neonates of low-anxiety mothers (p<0.001). Considering maternal depression and anxiety simultaneously, only the effect of maternal anxiety was found on these markers of fetal-neonatal growth outcomes and trajectories. This study demonstrates the independent longitudinal effect of maternal anxiety on major markers of fetal-neonatal growth outcomes and trajectories, simultaneously considering the effect of maternal depression and anxiety.

    2015-07-06

    Tetanus is an acute, often fatal, disease caused by an exotoxin produced by Clostridium tetani. It occurs in newborn infants born to mothers who do not have sufficient circulating antibodies to protect the infant passively, by transplacental transfer. Prevention may be possible by the vaccination of pregnant or non-pregnant women, or both, with tetanus toxoid, and the provision of clean delivery services. Tetanus toxoid consists of a formaldehyde-treated toxin that stimulates the production of antitoxin. To assess the effectiveness of tetanus toxoid, administered to women of reproductive age or pregnant women, to prevent cases of, and deaths from, neonatal tetanus. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2015), CENTRAL (The Cochrane Library 2015, Issue 1), PubMed (1966 to 28 January 2015), EMBASE (1974 to 28 January 2015) and reference lists of retrieved studies. Randomised or quasi-randomised trials evaluating the effects of tetanus toxoid in pregnant women or women of reproductive age on numbers of neonatal tetanus cases and deaths. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Two effectiveness trials (9823 infants) and one safety trial (48 mothers) were included. The main outcomes were measured on infants born to a subset of those randomised women who became pregnant during the course of the studies. For our primary outcomes, there was no high-quality evidence according to GRADE assessments.One study (1182 infants) assessed the effectiveness of tetanus toxoid in comparison with influenza vaccine in preventing neonatal tetanus deaths. A single dose did not provide significant protection against neonatal tetanus deaths, (risk ratio (RR) 0.57, 95% confidence interval (CI) 0.26 to 1.24; 494 infants; GRADE: low-quality evidence). However, a two- or three-dose course did provide protection against neonatal deaths, (RR 0.02, 95% CI 0.00 to 0

    Objectives: Placenta previa is a major cause of neonatal anemia. The purpose of this study was to elucidate the risk factors of neonatal anemia in placenta previa. Methods: The study was conducted on 158 placenta previa patients at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 through December 2009. The subjects were divided in to 2 groups: 47 placenta previa patients with neonatal anemia, and 113 placenta previa patients without neonatal anemia. The subjects' characteristics were compared. Logistic regression was used to control for confounding factors. Results: Anterior placental location (OR 2.48; 95% CI: 1.20-5.11) was an independent risk factor of neonatal anemia after controlling for potential confounders. Conclusion: To manage neonatal anemia in placenta previa patients, obstetricians should do their best to detect placental location. Pediatricians should consider the high possibility of neonatal anemia in cases involving anterior placental location. PMID:21960747

  14. Neonatal nursing: an unmet challenge in India.

    2014-11-01

    Nurses comprise a key component to maternal and newborn health care delivery, including the care of 'at-risk' or sick newborns. However, the efficiency and effectiveness of services rely heavily on adequate numbers of highly skilled neonatal nurses. Currently, in India, a significant shortage of trained nurses in the field of newborn care is contributing to poor neonatal outcomes. Specifically, nurses caring for newborns lack the competency and experience needed to ensure optimal care. This deficiency has been linked to a lack of expert faculty, standardized training and minimal or no exposures to newborn clinical care areas during pre service education. Moreover, in addition to a lack of operational research in the area, nurses who provide care for newborns are often faced with numerous system related issues that impede their ability to provide optimal care. Most notably, frequent changes of work place, poor wages, and lack of continuing education, skill maintenance, recognition, and collaborative team culture further compromise the nursing care. All these lead to poor motivation and competency. To meet this challenge, it is essential that emphasis be placed on the identification and support of nursing faculty with expertise in newborn and neonatal care who are able to ensure that nurses receive standardized education for pre-service, in-service and ongoing care. In addition, importance should be placed on encouraging newborn nursing research as well as on governmental increases in salary compensation. Lastly, given the shortage of physicians to take care of sick neonates in remote areas, the creation of a cadre of Neonatal nurse practitioner/ advanced practice nurses would be an invaluable solution in developing countries. Furthermore, centralized oversight of newborn education and training would be best served, if responsibility was placed with Reproductive maternal newborn child health (RMNCH) workers and district level officers.

    An investigation of stillbirth and early neonatal lamb mortality was conducted in sheep flocks in Norway. Knowledge of actual causes of death are important to aid the interpretation of results obtained during studies assessing the risk factors for lamb mortality, and when tailoring preventive measures at the flock, ewe and individual lamb level. This paper reports on the postmortem findings in 270 liveborn lambs that died during the first 5 days after birth. The lambs were from 17 flocks in six counties. A total of 27% died within 3 h after birth, 41% within 24 h and 80% within 2 days. Most lambs (62%) were from triplet or higher order litters. In 81% of twin and larger litters, only one lamb died. The most frequently identified cause of neonatal death was infectious disease (n=97, 36%); 48% (n=47) of these died from septicaemia, 25% (n=24) from pneumonia, 22% (n=21) from gastrointestinal infections and 5% (n=5) from other infections. Escherichia coli accounted for 65% of the septicaemic cases, and were the most common causal agent obtained from all cases of infection (41%). In total, 14% of neonatal deaths resulted from infection by this bacterium. Traumatic lesions were the primary cause of death in 20% (n=53) of the lambs. A total of 46% of these died within 3 h after birth and 66% within 24 h. Severe congenital malformations were found in 10% (n=27) of the lambs, whereas starvation with no concurrent lesions was the cause of death in 6% (n=17). In 16% (n=43) of the lambs, no specific cause of death was identified, lambs from triplet and higher order litters being overrepresented among these cases. In this study, the main causes of neonatal lamb mortality were infection and traumatic lesions. Most neonatal deaths occurred shortly after birth, suggesting that events related to lambing and the immediate post-lambing period are critical for lamb survival.

Baseline median CD4 T-cell count: 417 cell/μl; 98% received antiretroviral drugs during pregnancy [2 nucleoside analogs plus either nevirapine (55% or a protease inhibitor (32%]. Overall incidence of toxicity was 12.5%: rash (8%, anemia (3.5% and hepatotoxicity (1%. Rash was associated with exposure to nevirapine. Eighty one percent and 50% reached HIV-viral loads <1000 and <50 copies/ml at the end of pregnancy, respectively. Twenty six percent had obstetric complications and 16% had preterm delivery. Of the newborns, 1.6% had congenital defects and 9% had neonatal complications. Overall neonatal mortality was 1% and perinatal transmission was 0.7%. Protease inhibitor use and obstetric complications were associated to preterm delivery while obstetric complications were associated with neonatal complications. In our population, hepatotoxicity was low despite frequent use of nevirapine. Protease inhibitor use was associated to preterm delivery. A favorable virological response and a low rate of perinatal transmission was observed, what supports the consensus that antiretroviral therapy benefits during pregnancy outweigh risks of maternal and neonatal adverse events.

    Infants hospitalised in neonatology are inevitably exposed to pain repeatedly. Premature infants are particularly vulnerable, because they are hypersensitive to pain and demonstrate diminished behavioural responses to pain. They are therefore at risk of developing short and long-term complications if pain remains untreated. Compared to acute pain, there is limited evidence in the literature on prolonged pain in infants. However, the prevalence is reported between 20 and 40 %. This single case study aimed to identify the bio-contextual characteristics of neonates who experienced prolonged pain. This study was carried out in the neonatal unit of a tertiary referral centre in Western Switzerland. A retrospective data analysis of seven infants' profile, who experienced prolonged pain ,was performed using five different data sources. The mean gestational age of the seven infants was 32weeks. The main diagnosis included prematurity and respiratory distress syndrome. The total observations (N=55) showed that the participants had in average 21.8 (SD 6.9) painful procedures that were estimated to be of moderate to severe intensity each day. Out of the 164 recorded pain scores (2.9 pain assessment/day/infant), 14.6 % confirmed acute pain. Out of those experiencing acute pain, analgesia was given in 16.6 % of them and 79.1 % received no analgesia. This study highlighted the difficulty in managing pain in neonates who are exposed to numerous painful procedures. Pain in this population remains underevaluated and as a result undertreated.Results of this study showed that nursing documentation related to pain assessment is not systematic.Regular assessment and documentation of acute and prolonged pain are recommended. This could be achieved with clear guidelines on the Assessment Intervention Reassessment (AIR) cyclewith validated measures adapted to neonates. The adequacy of pain assessment is a pre-requisite for appropriate pain relief in neonates.

    Full Text Available Background: Intestinal obstruction is a life threatening condition in the newborn, with attendant high mortality rate especially in underserved subregion. This study reports the aetiology, presentation, and outcome of intestinal obstruction management in neonates. Materials and Methods: A prospective study of neonatal intestinal obstruction at the University of Benin Teaching Hospital, Benin, Nigeria, between January 2006-June 2008. Data were collated on a structured proforma and analysed for age, sex, weight, presentation, type/date of gestation/delivery, aetiology, clinical presentation, associated anomaly, treatment, and outcome. Results: There were 71 neonates, 52 were males and 19 were females (2.7:1. Their age range was between 12 hours and 28 days (mean, 7.9 ± 2.7 days and they weighed between 1.8 and 5.2 kg (average, 3.2 kg. The causes of intestinal obstruction were: Anorectal anomaly, 28 (39.4%; Hirschsprung′s disease, 8 (11.3%′ prematurity, 3 (4.2%; meconeum plug, 2 (2.8%; malrotation, 6 (8.5%; intestinal atresia, 8 (11.3%; necrotising enterocolitis (NEC, 4 (5.6%; obstructed hernia, 4 (5.6%; and spontaneous gut perforation, 3 (4.2%. Also, 27 (38% children had colostomy, 24 (33.8% had laparotomy, 9 (12.8% had anoplasty, while 11 (15.4% were managed nonoperatively. A total of 41 (57.7% neonates required incubator, 26 (36.6% needed total parenteral nutrition, while 15 (21.1% require d paediatric ventilator. Financial constraint, late presentation, presence of multiple anomalies, aspiration, sepsis, gut perforation, and bowel gangrene were the main contributors to death. Neonates with lower obstructions had a better outcome compared to those having upper intestinal obstruction ( P < 0.0001. Conclusion: Outcomes of intestinal obstruction are still poor in our setting; late presentation, financial constraints, poor parental motivation and lack of basic facilities were the major determinants of mortality.

    Full Text Available Background: Chickenpox is a very contagious viral disease that caused by varicella-zoster virus, which appears in the first week of life secondary to transplacental transmission of infection from the affected mother. When mother catches the disease five days before and up to two days after the delivery, the chance of varicella in neonate in first week of life is 17%. A generalized papulovesicular lesion is the most common clinical feature. Respiratory involvement may lead to giant cell pneumonia and respiratory failure. The mortality rate is up to 30% in the case of no treatment, often due to pneumonia. Treatment includes hospitalization, isolation and administration of intravenous acyclovir. The aim of this case report is to introduce the exogenous surfactant replacement therapy after intubation and mechanical ventilation for respiratory failure in neonatal chickenpox pneumonia and respiratory distress. Case Presentation: A seven-day-old neonate boy was admitted to the Neonatal Intensive Care Unit at Amirkola Children’s Hospital, Babol, north of Iran, with generalized papulovesicular lesions and respiratory distress. His mother has had a history of Varicella 4 days before delivery. He was isolated and given supportive care, intravenous acyclovir and antibiotics. On the second day, he was intubated and connected to mechanical ventilator due to severe pneumonia and respiratory failure. Because of sever pulmonary involvement evidenced by Chest X-Ray and high ventilators set-up requirement, intratracheal surfactant was administered in two doses separated by 12 hours. He was discharged after 14 days without any complication with good general condition. Conclusion: Exogenous surfactant replacement therapy can be useful as an adjunctive therapy for the treatment of respiratory failure due to neonatal chickenpox.

    Most pathologic conditions requiring emergent operation in neonate are congenital anomalies and delayed diagnosis and associated anomaly are important factors which have contributed to the high mortality rate of congenital anomalies. To prevent this delay, early recognition of the danger signals, adequate roentagenologic examination and accurate diagnosis should be made. Furthermore radiologists should be aware of developing mechanism, clinical manifestations and roentgenographic findings of those neonatal emergencies. 135 cases of neonatal emergencies were analyzed at this point of view, which verified by surgery and pathologic examination at Yonsei University College of Medicine, Severance Hospital since 1968. Embryology and characteristic roentgenographic pictures of each disease were discussed. The conclusions are as follows; 1. Most cases (110/135) presented intestinal obstruction. Imperforate anus (29 cases) was most common disease which followed by infantile hypertrophic pyloric stenosis (25 cases), small bowel atresia and stenosis (18 cases), congenital megacolon (15 cases) and esophageal atresia (14 cases). 2. Clinical Type and time of occurrence of symptoms and signs were so characteristic that these were helpful for differential diagnosis. 3. In infantile hypertrophic pyloric stenosis, confirmative diagnosis could be made in plain abdominal film, when 'Caterpillar sign' was seen. 4. When small bowel obstruction was suspected in plain abdominal film, barium enema examination was more helpful than upper G-I study. When microcolon was found, lower small bowel obstruction was highly suggested. 5. Diagnosis of midgut malrotation was possible in larger cases (4/7). Upper G-I examination was more valuable than barium enema study, because duodenal obstruction due to Ladd's band was common problem in neonate. 6. In neonatal period, diagnosis of aganglionosis could be made with the finding of barium stasis on 24-48 hours delay film, even though no

    Placental abruption (early separation of the placenta) is associated with preterm birth and perinatal mortality, but associations with other neonatal morbidities remain understudied. We examined the association between abruption and newborn outcomes. We analyzed 223,341 singleton deliveries from the Consortium on Safe Labor study, a retrospective, multisite, observational study (2002-2008) of electronic medical records in the United States. Adjusted relative risks, incidence rate ratios, and 99% confidence intervals were estimated. Direct effects attributable to abruption were examined by conditioning on intermediates (preterm birth and small for gestational age) with sensitivity analyses. Incidence of abruption was 1.6% (n = 3,619). Abruption was associated with an elevated risk of newborn resuscitation (relative risk (RR) = 1.5, 99% confidence interval (CI): 1.5, 1.6), apnea (RR = 5.8, 99% CI: 5.1, 6.5), asphyxia (RR = 8.5, 99% CI: 5.7, 11.3), respiratory distress syndrome (RR = 6.5, 99% CI: 5.9, 7.1), neonatal intensive care unit admission (RR = 3.4, 99% CI: 3.2, 3.6), longer intensive care length of stay (incidence rate ratio = 2.0, 99% CI: 1.9, 2.2), stillbirth (RR = 6.3, 99% CI: 4.7, 7.9), and neonatal mortality (RR = 7.6, 99% CI: 5.2, 10.1). In sensitivity analyses, there was a direct effect of abruption associated with increased neonatal risks. These findings expand our knowledge of the association between abruption and perinatal and neonatal outcomes. © The Author(s) 2017.

    Full Text Available Background: Neonate with abnormal weight is at risk of increased mortality and morbidity. Many factors affect pregnancy outcome. Because of the importance and vital role in birth weight, in this study, some of the factors associated with birth weight in a sample of Iranians neonates were investigated. Materials and Methods: In this cross-sectional study, 245 newborns in a sample of Iranians neonates in the year 2013 were selected, and characteristics of neonate and their mothers were derived. Birth weights were registered by the neonatal scale. To identify the direct and indirect factors affecting birth weight, we used path analysis (PA and IBM AMOS and SPSS software. Results: The mean ± standard deviation of weight in girls (3200 ± 421 g less than boys (3310 ± 444 g significantly (P = 0.04. Gestational age (P < 0.001, birth rank (P = 0.012, distance from a previous pregnancy (P = 0.028, and mother weight (P = 0.04 had a statistical significant relationship with birth weight. In the final PA model, gestational age has a highest total effect, type of delivery with gestational age-mediated had the highest indirect effect and type of delivery, and gestational age had the greatest total impact on the birth weight. Conclusion: Gestational age, sex, distance from a previous pregnancy, maternal weight, type of delivery, number of abortion, and birth rank were related with birth weight. Due to the termination of pregnancy and avoid unnecessary deliveries through cesarean section and other related factors should be further consideration by childbirth experts. In addition, factors affecting these variables are carefully identified and prevented as much as possible.

    Septic shock, occurring in about 1% of neonates hospitalized in neonatal intensive care unit (NICU), is a major cause of death in the neonatal period. In the 1980s and 90s, exchange transfusion (ET) was reported by some authors to be effective in the treatment of neonatal sepsis and septic shock. The main aim of this retrospective study was to compare the mortality rate of neonates with septic shock treated only with standard care therapy (ScT group) with the mortality rate of those treated w...

    Neonatal sepsis remains a serious problem in any neonatal intensive care unit (NICU). Bacterial organisms have developed increased resistance to commonly used antibiotics. Because not enough data are available from Egypt, the aim of the present study was to determine the causative bacteria and the level of their resistance to commonly used antibiotics in tertiary NICUs in Cairo, Egypt. A 3.5-year retrospective study was carried out at NICUs of the Children's Hospital of Ain Shams University and that of El-Hussein Hospital, Al-Azhar University, Egypt. Records of neonates were reviewed. All neonates with culture-proven sepsis were included in the study. Almost one-third of the admitted neonates (33.4%) were diagnosed as having neonatal sepsis, 32.25% of them culture-proven. Early/late onset sepsis was found in 35.4 and 64.6%, respectively. Gram-negative/gram-positive bacteria was found in 68 to 25.6%. Fungal infection was detected in 9% of the isolates. Escherichia coli was the main pathogen isolated in both early-onset sepsis (41.2%) and late-onset sepsis (24.5%). Overall, 77% of the isolates were multidrug-resistant (60% of gram-positive bacteria and 83.4% of gram-negative bacteria). Nearly 80% (79%) of mortality was caused by multidrug-resistant organisms. Gram-positive and gram-negative bacteria showed high resistance against commonly used antibiotics such as ampicillin, amoxicillin, cefotaxime, ceftriaxone, and gentamicin. There is an alarming increase in antibiotic resistance to the commonly used antibiotics. Continuous surveillance for antibiotic susceptibility is needed to ensure proper empirical therapy. Improvement of infection control practices, avoidance of irrational use of antibiotics, and revision of the protocols are mandatory in the prevention of neonatal sepsis.

    Objectives: To determine the incidence and pattern of various congenital heart disease in a neonatal unit of a tertiary care hospital. Methods: The prospective study was carried out in the neonatal unit of Combined Military Hospital, Rawalpindi, from September 2008 to August 2011. All 5800 neonates admitted with gestational age of >28 weeks irrespective of birthweight were included in the study. Neonatologist/Paediatrician carried out the neonatal examination during the first 12 hours of life. Neonates suspected of having congenital heart disease were further evaluated by pulse oxymetry, X-ray chest and echocardiography to ascertain final diagnosis and type of lesion. Data was collected on a predesigned proforma containing information regarding gender, mode of delivery, gestational age, weight at birth, family history, and associated malformations. SPSS 16 was used for statistical analysis. Results: Of the 5800 neonates, 87 (1.5%) were found to have congenital heart disease with an incidence of 15/1000. There was a male preponderance. Most common lesion was ventricular septal defect 27(31.3%), followed by atrial septal defect 20 (22.9%), patent ductus arteriosus 13 (14.94%), tetralogy of fallot 06 (6.89%), transposition of great arteries 04 (4.59%), Pulmonary stenosis 05 (5.79%) and 03(3.44%) had atrioventricular canal defects. Conclusion: Congenital heart disease is a common congenital anomaly. Its incidence varies from centre to centre due to different factors like nature of the sample, method of detection and early examination by a neonatologist/paediatrician. In this study a higher incidence is reported because it was carried out in a tertiary care unit, which is a referral hospital and all the neonates admitted in the unit were included in the study.

    Full Text Available Identifying single nucleotide polymorphisms (SNPs in the genes involved in sepsis may help to clarify the pathophysiology of neonatal sepsis. The aim of this study was to evaluate the relationships between sepsis in pre-term neonates and genes potentially involved in the response to invasion by infectious agents. The study involved 101 pre-term neonates born between June 2008 and May 2012 with a diagnosis of microbiologically confirmed sepsis, 98 pre-term neonates with clinical sepsis and 100 randomly selected, otherwise healthy pre-term neonates born during the study period. During the study, 47 SNPs in 18 candidate genes were genotyped on Guthrie cards using an ABI PRISM 7900 HT Fast real-time and MAssARRAY for nucleic acids instruments. Genotypes CT and TT of rs1143643 (the IL1β gene and genotype GG of rs2664349GG (the MMP-16 gene were associated with a significantly increased overall risk of developing sepsis (p = 0.03, p = 0.05 and p = 0.03, whereas genotypes AG of rs4358188 (the BPI gene and CT of rs1799946 (the DEFβ1 gene were associated with a significantly reduced risk of developing sepsis (p = 0.05 for both. Among the patients with bacteriologically confirmed sepsis, only genotype GG of rs2664349 (the MMP-16 gene showed a significant association with an increased risk (p = 0.02. Genotypes GG of rs2569190 (the CD14 gene and AT of rs4073 (the IL8 gene were associated with a significantly increased risk of developing severe sepsis (p = 0.05 and p = 0.01. Genotype AG of rs1800629 (the LTA gene and genotypes CC and CT of rs1341023 (the BPI gene were associated with a significantly increased risk of developing Gram-negative sepsis (p = 0.04, p = 0.04 and p = 0.03. These results show that genetic variability seems to play a role in sepsis in pre-term neonates by influencing susceptibility to and the severity of the disease, as well as the risk of having disease due to specific pathogens.

    Full Text Available Premature rupture of membranes (PROM is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. With respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following PROM and the role of the duration of rupture of membranes in producing morbidities and mortalities in these neonates in our hospital. Among 2357 pregnant women, we found 163 (6.91% cases of premature rupture of the fetal membranes in Tehran Vali-e-Asr Hospital during April 2001 to April 2002. Route of delivery was cesarean section in 65.6% of women. Urinary tract infection occured in 1.8%, maternal leukocytosis and fever in 20.2% and 5.5%, chorioamnionitis in 6.1%, fetal tachycardia in 1.2% and olygohydramnios in 4.9%. Gestational age in 138 (86% of neonates was less than 37 completed weeks. Thirty five infants (21.47% had respiratory distress syndrome and 33 (20.245% had clinical sepsis. Pneumonia in 6 (3.7% and skeletal deformity in 7 (4.294% were seen. Rupture of membrane of more than 24 hours duration occurred in 71 (43.6% of the patients. Comparison of morbidities between two groups of neonates and their mothers according to the duration of PROM (less and more than 24 hours showed significant differences in NICU admission, olygohydramnios, maternal fever, leukocytosis and chorioamnionitis rates (p24 hr of PROM with an odds ratio of 2.68 and 2.73, respectively. Positive blood and eye cultures were detected in 16 cases during 72 hours of age. Staphylococcus species, klebsiella, E.coli and streptococcus were the predominant organisms among positive blood cultures. Mortality was seen in 18 (11% of neonates because of respiratory failure, disseminated intravascular coagulation, septic shock, and a single case of congenital toxoplasmosis.

    Full Text Available Background: Epidural analgesia is the most effective analgesics used during childbirth but is not without its problems.In the Hospital San Juan de la Cruz of Ubeda from November 2011 we have detected 3 cases of newborn infants with signs of respiratory depression. Appeared in them: normal cardiotocographic records during childbirth, use of epidural associated with fentanyl, termination by vacuum and elevated temperature in one case.ObjectivesKnow if the neonatal adaptation to extrauterine life may be influenced by the use of epidural analgesia in childbirth. Review what role can have the rise in maternal temperature and the use of epidural fentanyl with the appearance of newborn respiratory distress.MethodsLiterature Review conducted in February of 2012 in Pubmed and the Cochrane Library, using the key words: childbirth, epidural analgesia, neonatal respiratory depression.ResultsOn the respiratory depression associated with fentanyl, a Cochrane review found indicating that newborns of mothers with an epidural, had a lower pH and were less need for administration of naloxone.On PubMed we find a review study that indicates that the respiratory depression caused by the administration of opioids via neuroaxial is rare, placing it below 1 per 1000, and a clinical case that concluded that doses of fentanyl exceeding 300 µg (approx. 5 µg/kg for 4 hours previous to childbirth, have a high risk of neonatal respiratory depression at birth.The same Cochrane review indicates that the women with epidural analgesia had increased risk of maternal fever of at least 38 ° C and a recent cohort study relates this increase in temperature with a greater likelihood of neonatal adverse events (from 37.5 ° C.ConclusionsThe studies found considered safe epidurals to the neonate and the mother, except when certain conditions are met. The literature and our clinical experience have been reports linking neonatal respiratory depression with increasing temperature (37

As a result, there are high rates of morbidity and mortality. The three major causes of mortality in developing countries include prematurity, infection, and perinatal asphyxia. The aim of this study was to identify the patterns of neonatal admission and factors associated with mortality among neonates admitted at the Neonatal Intensive Care Unit (NICU of University of Gondar Hospital.Materials and methods: A retrospective cross-sectional study was conducted among all admitted neonates in the NICU of University of Gondar referral hospital from December 1, 2015 to August 31, 2016. Information was extracted retrospectively during admission from patient records and death certificates, using a pretested questionnaire. The data were entered and analyzed using SPSS version 20, and p-values <0.05 were considered statistically significant.Results: A total of 769 neonates was included in the study. There were 448 (58.3% male neonates, and 398 (51.8% neonates were rural residents. More than two-thirds of the 587 deliveries (76.3% were performed in tertiary hospitals.

    To identify the use and adverse drug reactions associated with azithromycin in neonates. Databases MEDLINE (1948-August 2015), EMBASE (1980-August 2015) and Pubmed (August 2015) were searched for studies on azithromycin in neonates. All studies involving neonates (azithromycin for which safety was evaluated. The primary outcome was adverse event (AE) associated with use of azithromycin. Use of azithromycin in neonates was the secondary outcome. A total of 11 articles involving 473 neonates were identified. 371 AEs were reported. Adverse events were mainly respiratory (358/1000 neonate), neurological (273/1000 neonates) and gastrointestinal (196/1000 neonates) in origin. Azithromycin significantly reduced the risk of bronchopulmonary dysplasia (BPD) in extremely premature neonates (RR=0.83, 95% CI 0.71 to 0.98, p=0.02). There was no significant difference in the incidence of elevated liver enzymes between the azithromycin and placebo group (p=0.76). There were four cases of infantile hypertrophic pyloric stenosis (IHPS). Azithromycin significantly reduces the risk of BPD in preterm neonates. The relationship between azithromycin and IHPS requires further investigation. Published by the BMJ Publishing Group Limited.

    This study aims to evaluate adherence to a clinical guideline for screening and prevention of neonatal hypoglycaemia on the post-natal wards. Retrospective chart review of 581 healthy term neonates born at a tertiary maternity hospital. Indications for hypoglycaemia screening included small for gestational age (SGA), infants of diabetic mothers (IDM; gestational, Type 1 or 2), symptomatic hypoglycaemia, macrosomia and wasted (undernourished) appearance. Outcomes were protocol entry and adherence with hypoglycaemia prevention strategies including early and frequent feeding and timely blood glucose measurement. Of 115 neonates screened for hypoglycaemia, 67 were IDM, 19 were SGA (including two both IDM and SGA), and two were macrosomic. One IDM and one SGA were not screened. Twenty-two neonates were screened for a reason not identifiable from the medical record, and 13 neonates were SGA by a definition different to the guideline definition, including five who were also IDM. Guideline adherence was variable. Few neonates (41 of 106, 39%) were fed in the first post-natal hour, and blood glucose measurement occurred later than recommended for 41 of 106 (39%) of neonates. Most IDM and SGA neonates were screened. While guideline adherence overall was comparable with other studies, neonates were fed late. We recommend staff education about benefits of early (within the first hour) frequent breastfeeding for neonates at risk. © 2013 The Authors.

    Body composition in early life influences the development of obesity during childhood and beyond. It is, therefore, important to adequately determine neonatal body composition. Fetal growth and maternal factors might influence neonatal fat mass percentage (FM%), independent of birth weight. In 194 healthy neonates, we investigated neonatal body composition, measured by air-displacement plethysmography (PEAPOD), and its associations with estimated fetal weight (EFW), neonatal anthropometric data, maternal preconceptional body mass index (BMI) and maternal weight gain during pregnancy. There was a large variation in neonatal FM%, even in case of a similar birth weight, corrected for gender and gestational age. Neonatal FM% was associated with EFW at 30 and 36 weeks of gestation and with catch-up in weight between 30 and 36 weeks of gestation, but not with EFW at 20 weeks (p Neonatal FM% was also associated with preconceptional BMI of the mother (p maternal weight gain. Our study shows that term neonates have a large variation in FM%. Neonatal FM% is associated with EFW at 30 and 36 weeks, catch-up in weight between 30 and 36 weeks of gestation and preconceptional BMI of the mother. © 2015 S. Karger AG, Basel.

    IntroductionThe surgical treatment of the acute neonatal abdomen still poses a challenge in pediatric surgery. Various underlying etiologies require different surgical procedures. Until today the role of laparoscopy in the surgical treatment of the acute neonatal abdomen is controversial. The aim of this study was to analyze our experiences with laparoscopy and to perform a review of the literature. Methods Retrospective, single-institution study including all term and preterm neonates initially undergoing laparoscopy due to an acute abdomen. Results Altogether, 17 neonates presenting with an acute neonatal abdomen initially underwent laparoscopy. Unnecessary laparotomy could be avoided in 9 of 17 (53%) neonates. After diagnostic laparoscopy, 2 patients did not require any further surgical intervention. Eight neonates presented midgut atresia intraoperatively, 5 of them underwent laparoscopic-assisted correction. Successful laparoscopic derotation of an acute volvulus (n = 1) and laparoscopic appendectomy (n = 1) could be performed. Conversion to open surgery was necessary in 8 neonates (47%) due to creation of a stoma (n = 5), multiple intestinal bands causing poor visualization (n = 2), and bowel necrosis (n = 1). Conclusions Laparoscopy is a useful diagnostic tool to evaluate the need for further surgical intervention in the acute neonatal abdomen and enables immediate surgical treatment of acute volvulus, appendicitis, or intestinal atresia. In case of conversion to laparotomy, precise localization of the incision is guaranteed. Minimization of the surgical trauma and avoidance of unnecessary laparotomy are the most important benefits of the minimal-invasive approach for the critically ill neonate. © The Author(s) 2016.

    Neonatal mortality is a public health concern, and congenital anomalies contribute significantly to this mortality. This paper describes trends in neonatal mortality in Malta separately for congenital anomaly and non-congenital anomaly causes. Data for neonatal deaths of 22-week gestation onwards registered between 1994-2013 were obtained from the National Mortality Register. Chi-square tests were used to analyse 5-year time trends and differences in proportions of causes of neonatal deaths. Neonatal mortality was compared with other European countries. Between 1994 and 2013, 441 neonatal deaths and 84 821 livebirths were registered, giving a neonatal mortality of 5.2 per 1000 livebirths. Congenital anomalies accounted for 36.7% (n = 162) of the neonatal deaths, while the remaining 63.3% (n = 279) were attributed to non-congenital causes. During the 20-year period, neonatal mortality due to non-congenital causes decreased from 4.6 per 1000 livebirths in 1994-98 to 2.5 per 1000 in 2009-13, while that due to congenital anomalies remained stable (2.0 per 1000 livebirths in 1994-98 and 2.2 per 1000 in 2009-13). This has resulted in comparatively higher proportions of neonatal deaths attributed to congenital anomalies in recent years (45.9% in 2009-13 vs. 29.9% in 1994-98). Comparing neonatal mortality reported from European countries, Malta has a high rate most marked for deaths due to congenital anomalies. During 1994-2013, neonatal mortality has decreased due to a decline of non-congenital causes of death, possibly related to improved health care. The proportionate neonatal mortality attributed to congenital anomalies has increased and is the highest reported from Europe. This may be explained by the fact that termination of pregnancy is illegal in Malta. © 2015 John Wiley & Sons Ltd.

    Full Text Available Background Rhesus incompatibility is a preventable cause for severe neonatal hyperbilirubinemia, hydrops fetalis and still births. The prevalence of the Rh-negative blood group among Indian woman varies from 2% - 10%. Despite declining the incidence of Rhesus incompatibility, due to availability of anti-D immunoglobulin, and improved antenatal care of the Rh-negative pregnant woman, it still accounts for a significant proportion of neonatal hyperbilirubinemia and neuro-morbidity. The prevalence of Rh-negative women having Rh-positive neonates is 60%. Objectives This study aimed to estimate the incidence of Rh iso-immunization and evaluate the outcomes of Rh iso-immunized neonates. Methods This prospective observational study was conducted in a tertiary level neonatal intensive care unit, Princess Esra hospital, Deccan college of medical sciences, Hyderabad, Telangana, India. Consecutive intramural and extramural neonates admitted to neonatal intensive care unit with the Rh-negative mother’s blood group and hyperbilirubinemia were enrolled. Neonates born to Rh+ve mothers were excluded. Neonatal gestational age, birth weight, age at admission, duration of phototherapy, duration of hospitalization, neonatal examination and investigations were recorded in a predesigned, pretested performa. Results A total of 90 neonates were born to Rh-negative mothers, of which 70% (63 had the Rh-positive blood group and 30% had the Rh-negative blood group. Of these 63 neonates, 48 (76.2% had hyperbilirubinemia and 43 neonates (68.3% had significant hyperbilirubinemia (total serum bilirubin > 15mg/dL. Among them, 2%, 75% and 23% were born to primi, multi and grandmutli, respectively. Also, 14.5% of the neonates were large for dates (LFD, 75% appropriate for dates (AFD and 10.5% were small for dates (SFD. Premature and SFD neonates had higher incidence of hyperbilirubinemia.

    Neonatal nutrition adequacy is often determined by infant weight gain. The aim of this review is to summarize what is currently known about neonatal body composition and the use of body composition as a measure for adequate neonatal nutrition. Unlike traditional anthropometric measures of height and weight, body composition measurements account for fat vs nonfat mass gains. This provides a more accurate picture of neonatal composition of weight gain. Providing adequate neonatal nutrition in the form of quantity and composition can be a challenge, especially when considering the delicate balance of providing adequate nutrition to preterm infants for catch-up growth. Monitoring weight gain as fat mass and nonfat mass while documenting dietary intake of fat, protein, and carbohydrate in formulas may help provide the medical community the tools to provide optimal nutrition for catch-up growth and for improved neurodevelopmental outcomes. Tracking body composition in term and preterm infants may also provide critical future information concerning the nutritional state of infants who go on to develop future disease such as obesity, hypertension, and hyperlipidemia as adolescents or adults. © 2015 American Society for Parenteral and Enteral Nutrition.

    Full Text Available AIM: To explore the treatment of neonatal dacryocystitis of different ages and the relationship between caesarean section and neonatal dacryocystitis.METHODS: A total of 260 cases(260 eyesof children with neonatal dacryocystitis were divided into 1-3 months group, 4-6 months group, 7-12 months group and 13-24 months group, Each group was respectively given the lacrimal sac massage, lacrimal passage irrigation and probing of lacrimal passage method. Curative effect of each method was observed in different groups. Analysis was made to determine whether caesarean section was the cause of neonatal dacryocystitis.RESULTS: The comparison between 1-3 months group and 4-6 months group showed significant difference(χ2=19.89, Pχ2=54.95, Pχ2=0.00003, P>0.05, lacrimal passage irrigation of these two groups showed no significant difference in efficacy. The comparison result between the other two groups showed no significant difference(Pχ2=10.29, PCONCLUSION:Lacrimal sac massage can exert very good therapeutic effects in infants less than 3 months. The curative effects of irrigation of lacrimal passage are quite good in babies under 12 months. Probing of lacrimal passage has a good curative effect in 7-12 months infants, but a poor curative effect in babies over 12 months. Caesarean section is an important cause for neonatal dacryocystitis.

    In diagnostic imaging of thoracic pathologies in mature and especially immature neonates, chest X-ray has a leading position. Profound knowledge of the normal chest X-ray and the potential physiological perinatal changes is the basic requirement for interpretation of the X-ray of a neonate. Childhood pathologie: Many congenital and acquired diseases that the radiologist is faced with in neonatology are unknown in the imaging of adults. Many of these changes are life-threatening or may have an impact on the patient's future quality of life. Therefore, early diagnosis in close cooperation with the paediatrician is essential. We give here an overview of the most important pathologic changes that the radiologist may be confronted with in daily routine. (orig.) [de

  1. The management of neonatal pulmonary hypertension.

    2012-05-01

    Most neonates with clinically significant pulmonary hypertension (PH) will have either persistent PH of the newborn (PPHN) or bronchopulmonary dysplasia. Cyanotic congenital heart disease must be actively ruled out as part of the differential diagnosis of PPHN. The maintenance of ductal patency with prostaglandins E1 or E2 in cases of doubt is safe and potentially beneficial given their pulmonary vasorelaxant properties. Specific tools in the treatment of PPHN include modern ventilatory strategies, inhaled nitric oxide, sildenafil, prostacyclin and extracorporeal membrane oxygenation. Rarely will a cardiac lesion be primarily responsible for neonatal PH although pulmonary vein stenosis and the persistence of an arterial duct must be considered, particularly in the older preterm baby with bronchopulmonary dysplasia.

    2014-02-01

    Counseling a family confronted with the birth of a periviable neonate is one of the most difficult tasks that a neonatologist must perform. The neonatologist's goal is to facilitate an informed, collaborative decision about whether life-sustaining therapies are in the best interest of this baby. Neonatologists are trained to provide families with a detailed account of the morbidity and mortality data they believe are necessary to facilitate a truly informed decision. Yet these complicated and intensely emotional conversations require advanced communication and counseling skills that our current fellowship-training strategies are not adequately providing. We review educational models for training neonatology fellows to provide antenatal counseling at the threshold of viability. We believe that training aimed at teaching these skills should be incorporated into the neonatal-perinatal medicine fellowship. The optimal approaches for teaching these skills remain uncertain, and there is a need for continued innovation and outcomes-based research. Published by Elsevier Inc.

  3. Molecular Mechanisms of Neonatal Brain Injury

    2012-01-01

    Full Text Available Fetal/neonatal brain injury is an important cause of neurological disability. Hypoxia-ischemia and excitotoxicity are considered important insults, and, in spite of their acute nature, brain injury develops over a protracted time period during the primary, secondary, and tertiary phases. The concept that most of the injury develops with a delay after the insult makes it possible to provide effective neuroprotective treatment after the insult. Indeed, hypothermia applied within 6 hours after birth in neonatal encephalopathy reduces neurological disability in clinical trials. In order to develop the next generation of treatment, we need to know more about the pathophysiological mechanism during the secondary and tertiary phases of injury. We review some of the critical molecular events related to mitochondrial dysfunction and apoptosis during the secondary phase and report some recent evidence that intervention may be feasible also days-weeks after the insult.

  4. Neonatal appendicitis: a survival case study

    Izabela Linha Secco

    Full Text Available ABSTRACT Objective: To report a case of neonatal appendicitis in a children’s hospital in southern Brazil, demonstrating the impact on neonatal survival. Method: Case study with data collection from medical records, approved by the Institution and Ethics Committee for Research with Human Beings. Results: The clinical picture is initially characterized by food intolerance, evolving to hypoactivity, alteration of vital signs and septicemia due to intestinal perforation. Management is exclusively surgical, since no case described in the literature was diagnosed preoperatively and the findings usually point to acute abdomen. Conclusion: A focused clinical surveillance should be established when the infant presents peritoneal irritation. Follow-up of the evolution and the worsening of the symptoms by nurses, as part of the care team in partnership with the medical team, enables an early surgical intervention, thereby avoiding complications such as septicemia and death.

    53 cases of neonatal listeriosis were seen during the last five years at the Intensive Care Unit for newborn infants (Pr Minkowski) and the Neonatal Center (P. Varangot) of the Port-Royal Maternity Hospital. The significant decline in mortality to 22 p. 100, when compared with previous years, was attributed to improvements in the diagnosis during the first hours of life and the contribution of artificial ventilation. The most frequent initial clinical sign was respiratory distress (58 p. 100) whereas meningitis was relatively rare (11 p. 100). Discoloration of the amniotic fluid and a fever in the mother at the time of delivery, were also important diagnostic clues. The macroscopic examination of the placenta and particularly placental smears containing listeria monocytogenes (15 of the specimens) as well as the hematological alterations, particularly an increase of the fibrinogen level above 3-4 g/1 during the first 48 hous of life (72 p. 100 of the cases) contributed to an early diagnosis.

    Fetal water balance is dependent prenatally on the placental transfer of water from maternal to fetal circulation. Adequate amniotic fluid volume is one indicator of stable fetal status and development. Excessive or less than expected amniotic fluid volume may be a precursor to postnatal morbidity and mortality. Postnatal transition is marked by predictable changes in body water including contraction of extracellular volume and insensible fluid loss, primarily across the skin barrier. The degree to which these occur is determined by gestational and postnatal age. Neonatal complications and clinical conditions associated with either retention or excessive loss of body water can occur. Fluid therapy in the neonatal intensive care unit may be guided using three clinical indicators: change in body weight, serum sodium concentration, and urine output. Copyright © 2017 Elsevier Ltd.

    'Neonatal' lupus erythematosus (NLE) describes a clinical spectrum of cardiac and non-cardiac abnormalities observed in neonates and foetuses whose mothers have the auto-antibodies anti-SSA/Ro (anti-Ro) and anti-SSB/La (anti-La). Of the cardiac abnormalities, congenital AVB is the most common cardiovascular abnormality found in affected foetuses and infants. Many other cardiovascular manifestations of NLE have been more recently recognized including atrial and ventricular arrhythmias and other conduction abnormalities, myocarditis, cardiomyopathy often with endocardiofibroelastosis and structural heart disease, particularly valvar lesions. In this report, the spectrum of cardiovascular manifestations observed in foetuses and infants with NLE are reviewed and the pathogenesis, diagnosis and clinical outcomes are briefly discussed.

    2014-09-01

    The rising incidence of whooping cough, a highly contagious infection caused by Bordetella pertussis, is particularly significant for young infants who have the highest risk for morbidity and mortality. The pertussis resurgence has led to a shift in primary prevention relying on childhood vaccination to a cocooning strategy, that is, vaccination of close contacts of newborn infants (new mothers, fathers, grandparents, siblings, caretakers, etc.), thereby reducing pertussis exposure. Immunization of women during pregnancy rather than during the immediate postpartum period (the initial cocooning recommendation) appears to be a better approach by directly providing protection through transplacental transfer of maternal vaccine-induced antibodies. This article describes neonatal pertussis, cocooning as a means of reducing neonatal exposure to pertussis and maternal immunization as a means of protecting young infants against pertussis infection.

The risks of brachial plexus birth injury, clavicle and humeral fracture, perinatal asphyxia, hypoxic-ischemic encephalopathy and perinatal mortality are increased after shoulder dystocia. The medical team should be able to provide neonatal resuscitation in the delivery room in case of perinatal asphyxia following shoulder dystocia, according to national and international guidelines. The initial clinical examination should search for complications such as brachial plexus birth injury or clavicle fracture. The risk of perinatal complications is increased in newborn after shoulder dystocia. The medical team should be able to manage these complications. Copyright © 2015 Elsevier Masson SAS.

    2013-05-01

    Vitamin D deficiency is widespread in the neonatal and paediatric population of northern latitudes, particularly in children of African, Middle Eastern and Asian ethnicity. This is associated with diminished immune function and increases the risk of Th1 autoimmune diseases like type 1 diabetes. Epidermiological studies have also shown a link between vitamin D deficiency in children and a more severe course of illness with lower respiratory tract infection or Respiratory Syncitial Virus (RSV) bronchiolitis. The mechanism by which vitamin D enhances immunity is complex. It acts through the innate immune system by inducing antimicrobial peptides in epithelial cells, neutrophils and macrophages. The role of Vitamin D in neonatal and paediatric immunomodulation requires further study.

    Aim of this study was to analyze neonatal mortality and morbidity in the post-implementation period of a neonatal teaching program to examine a possible impact on neonatal outcomes. This study is a retrospective data analysis of all neonatal patients treated in five provincial hospitals in Laos after implementation of a neonatal teaching program. A simulation-based teaching program aims to have positive impact on the theoretical and practical skill of hospital staff in the field of newborn care. A comparison between pre-implementation and post-implementation data of newborns admitted to provincial hospitals in Laos was used to quantify the effect of repetitive teaching on neonatal outcomes. Neonatal mortality and morbidity as well as case fatality rates of infections and asphyxia decreased in the post-implementation period. In contrast, neonatal mortality rate as well as case fatality rate of prematurity increased. The total neonatal mortality rate increased in the post-implementation period. The pre-implementation and post-implementation data enable longitudinal comparisons between hospitals and highlight the differences between hospitals concerning neonatal mortality and morbidity in provincial hospitals in Laos. These data can serve as a basis for an individual adaption of the teaching program to the unique requirements of each single hospital. Copyright © 2017 The Royal Society for Public Health.

This study reports the evaluation and validation of these scales in full-term newborns who were hospitalized in two Greek neonatal intensive care units. Evaluation and validation of the Neonatal Infant Pain Scale and the Premature Infant Pain Profile in full-term newborns who were hospitalized in two Greek neonatal intensive care units. A cross-sectional study. Two neonatal intensive care units at a large General Children's Hospital in Greece. A total of 81 full-term newborns. This cross-sectional study was conducted in two neonatal intensive care units at a large General Children's Hospital in Greece. We studied 81 full-term newborns, who were exposed to various painful routine procedures. A single measurement was taken from each neonate. Two observers were present during each procedure and evaluated pain using both the Neonatal Infant Pain Scale and Premature Infant Pain Profile. Internal consistency coefficient Cronbach's α, internal class agreement coefficient, and κ factor were appropriately measured. The weighting of the Neonatal Infant Pain Scale and Premature Infant Pain Profile pointed out an excellent coherence between the two scales and agreement among the researchers. The internal consistency coefficient Cronbach's α was >.8 and the internal class agreement coefficient was >.98 for both scales, which indicates an excellent consistency between scales. The κ factor for Neonatal Infant Pain Scale was >.73 and for the Premature Infant Pain Profile it was >.6, which indicates a significant agreement among investigators. The Neonatal Infant Pain Scale and Premature Infant Pain Profile were successfully adjusted in Greek standards with reliability between the scales and among the researchers. Moreover, they constitute reliable tools for the evaluation of neonatal procedural pain in full-term newborns in Greece

    Abstract. Neonatal jaundice is very common in newborn infants. Although it is often a natural and transitional condition, some infants develop severe hyperbilirubinemia, in which unconjugated bilirubin in the serum may cross the blood-brain-barrier and cause bilirubin encephalopathy (acute bilirubin intoxication) or kernicterus (chronic bilirubin intoxication). To avoid these hazardous conditions, it is important to identify the infants at risk for developing severe hyperbilirubinemia. There ...

    Full Text Available Aim: The aim of the study was to analyze the etiology of early-onset neonatal infection (EONI, the risk factors, the forms and the time of its manifestation, and the tactics and outcomes of antibacterial treatment. Methods: During the prospective investigation, cases of newborns with diagnosed EONI and initial treatment in 2011 were analyzed. Four in-patient departments of Lithuania took part in the investigation. Results: In total, 18,778 newborns were included in the investigation. During the studied period, 209 cases of EONI were diagnosed: unspecified EONI in 168 (80.4% neonates, pneumonia in 20 (9.6%, and early-onset sepsis (EOS in 21 (10% neonates. Group B Streptococcus (GBS was responsible for 40% of microbiologically confirmed cases of sepsis. A negative blood culture was found in 11 newborns (52.4% treated for sepsis. In all the cases, EONI was empirically treated with penicillin and gentamycin. The duration of antibacterial treatment varied between in-patient departments in Lithuania. During the studied period, 51.7% of women were screened for GBS colonization during pregnancy, and 21% of them had a positive vaginal culture for GBS; 78% of GBS carriers received intrapartum prophylactic antibiotics. Conclusions: The incidence of culture-confirmed early neonatal sepsis in Lithuania is similar to that indicated in the scientific literature, and is decreasing. Routine antenatal screening for GBS vaginal carriage in pregnant women is not universally performed in Lithuania. The duration of antibacterial treatment for EONI should be standardized in Lithuania.

    Toll-like receptors are vital transmembrane receptors that initiate the innate immune response to many micro-organisms. The discovery of these receptors has improved our understanding of host-pathogen interactions, and these receptors play an important role in the pathogenesis of multiple neonatal conditions such as sepsis and brain injury. Toll-like receptors, especially TLRs 2 and 4, are associated with necrotizing enterocolitis, periventricular leukomalacia and sepsis.

    Neonatal nurses report a great deal of ethical challenges in their everyday work. Seemingly trivial everyday choices nurses make are no more value-neutral than life-and-death choices. Everyday ethical challenges should also be recognized as ethical dilemmas in clinical practice. The purpose of this study is to investigate which types of ethical challenges neonatal nurses experience in their day-to-day care for critically ill newborns. Data were collected through semi-structured qualitative in-depth interviews. Phenomenological-hermeneutic analysis was applied to interpret the data. Six nurses from neonatal intensive care units at two Norwegian hospitals were interviewed on-site. The study is designed to comply with Ethical Guidelines for Nursing Research in the Nordic Countries and the Helsinki declaration. Findings suggest that nurses experience a diverse range of everyday ethical challenges related to challenging interactions with parents and colleagues, emotional strain, protecting the vulnerable infant, finding the balance between sensitivity and authority, ensuring continuity of treatment, and miscommunication and professional disagreement. A major finding in this study is how different agents involved in caring for the newborn experience their realities differently. When these realities collide, ethical challenges arise. Findings suggest that acting in the best interests of the child becomes more difficult in situations involving many agents with different perceptions of reality. The study presents new aspects which increases knowledge and understanding of the reality of nursing in a neonatal intensive care unit, while also demanding increased research in this field of care. © The Author(s) 2014.

  4. [Treatment of neonatal jaundice by efficient phototherapy].

    Science.gov (United States)

    Wiese, G

    1985-01-01

    Idiopathic neonatal jaundice derives from an initial insufficiency of all processes which metabolize hydrophobic bilirubin into diglucuronide excretable in bile. The term 'neonatal hyperbilirubinemia' should only be used when there is a potential risk of bilirubin intoxication. Thus, the concept hyperbilirubinemia is not necessarily linked to the exceeding of a certain threshold value, but rather to the maturity of the child and its clinical condition. In this sense, hyperbilirubinemia is, therefore, always a syndrome requiring treatment. Besides substitution transfusion, which is highly effective per se, but risky and costly, enzyme induction (e.g., by administration of phenobarbital) represents an elegant causal therapy; however, because of its slow onset of action, it has to be given prophylactically to almost all newborns. In addition, this method requires a general induction of all microsomal enzyme systems, and is hence a major intervention in the process of maturation of the neonatal enzyme systems. Therefore, phototherapy must be regarded as the treatment of choice in cases of idiopathic neonatal hyperbilirubinemia. It leads to a bypassing of the hepatic enzyme insufficiency in that by interaction between light with a wavelength of around 460 nm and the bilirubin molecules in the skin, an isomeric, water-soluble, renally secretable bilirubin is produced. The effect of phototherapy, i.e., the reduction in the serum bilirubin concentration under phototherapy, may be described as a simple e-function. The evaluation of this regular occurrence provides important information applicable to the phototherapy procedure: it should not be initiated prematurely, the duration of radiation should be as short as possible, the irradiated surface as large as possible, the radiation source should be exploited to a maximum by keeping the distance from the light source short and using lateral reflectors.

    Invasive candidiasis is an increasing problem in neonatal intensive care units worldwide and is an important cause of morbidity, mortality and prolongation of hospital stay. Despite administration of amphotericin B, invasive candidiasis in neonates is sometimes complicated by persistent fungemia and refractory invasive candidiasis. The problem has been augmented by the increasing prevalence of non-albicans species that often are resistant to fluconazole and to amphotericin B. The population consisted of 1 term and 9 premature neonates with invasive candidiasis caused by Candida albicans (n = 4), Candida parapsilosis (n = 3), Candida tropicalis (n = 2) and Candida glabrata (n = 1). Despite initial therapy with deoxycholate amphotericin B, blood cultures remained positive in all patients for 13-49 days. Invasive candidiasis progressed to meningitis and enlarging renal Candida bezoars in the kidney of one patient and an enlarging atrial vegetation in another. Another patient developed severe hypokalemia refractory to potassium supplementation. Two of the C. albicans and all of the non-albicans Candida isolates were resistant to fluconazole; the C. glabrata isolate was resistant to amphotericin B. Amphotericin B was discontinued and caspofungin initiated in all patients in a dosage of 1 mg/kg/d for 2 days followed by 2 mg/kg/d. All positive blood cultures cleared between 3 and 7 days after initiation of caspofungin, the atrial vegetation resolved and the renal Candida bezoars disappeared. Renal and hepatic function tests did not show any values above normal throughout caspofungin therapy. There were no attributable clinical adverse events during the administration of caspofungin in any of the patients. Caspofungin was effective, safe and well-tolerated as an alternative therapy for persistent and progressive candidiasis in those neonates who were unresponsive to or intolerant of deoxycholate amphotericin B.

    Full Text Available The application of palliative and hospice care to newborns in the neonatal intensive care unit (NICU has been evident for over 30 years. This article addresses the history, current considerations, and anticipated future needs for palliative and hospice care in the NICU, and is based on recent literature review. Neonatologists have long managed the entirety of many newborns’ short lives, given the relatively high mortality rates associated with prematurity and birth defects, but their ability or willingness to comprehensively address of the continuum of interdisciplinary palliative, end of life, and bereavement care has varied widely. While neonatology service capacity has grown worldwide during this time, so has attention to pediatric palliative care generally, and neonatal-perinatal palliative care specifically. Improvements have occurred in family-centered care, communication, pain assessment and management, and bereavement. There remains a need to integrate palliative care with intensive care rather than await its application solely at the terminal phase of a young infant’s life—when s/he is imminently dying. Future considerations for applying neonatal palliative care include its integration into fetal diagnostic management, the developing era of genomic medicine, and expanding research into palliative care models and practices in the NICU.

    Full Text Available Newborns and infants are often exposed to painful procedures during hospitalization. Several different scales have been validated to assess pain in specific populations of pediatric patients, but no single scale can easily and accurately assess pain in all newborns and infants regardless of gestational age and disease state. A new pain scale was developed, the COVERS scale, which incorporates 6 physiological and behavioral measures for scoring. Newborns admitted to the Neonatal Intensive Care Unit or Well Baby Nursery were evaluated for pain/discomfort during two procedures, a heel prick and a diaper change. Pain was assessed using indicators from three previously established scales (CRIES, the Premature Infant Pain Profile, and the Neonatal Infant Pain Scale, as well as the COVERS Scale, depending upon gestational age. Premature infant testing resulted in similar pain assessments using the COVERS and PIPP scales with an r=0.84. For the full-term infants, the COVERS scale and NIPS scale resulted in similar pain assessments with an r=0.95. The COVERS scale is a valid pain scale that can be used in the clinical setting to assess pain in newborns and infants and is universally applicable to all neonates, regardless of their age or physiological state.

    Abstract: Appendicitis is common in paediatric surgical praxis, but extremely rare in newborn infants. We report a premature male newborn from a twin pregnancy with gestational age of 31(+4) weeks, birth-weight 1580g, who underwent a laparotomy because of perforation. The baby was admitted to NICU after birth with transitory respiratory failure and early onset neonatal sepsis. MS-Staphylococcus epidermidis was isolated from blood culture, gastric contents and all peripheral specimens, C-reactive protein values were elevated after birth and significantly increased before surgery; thrombocytopenia and mild anemia were found. The control blood culture showed Candida albicans. At day 25 after birth life threatening deterioration occurred: feculent vomiting, progressing distension and palpable rigidity of the abdomen, absence of peristalsis, respiratory distress. Abdominal radiograph showed significantly distension of the intestines, air liquid levels, and discrete signs of pneumoperitoneum. The baby was transferred to the surgery with the diagnosis NEC with perforation. Appendicitis acuta gangrenosa perforativa and peritonitis fibrinopurulenta totalis were found intra-operatively but without signs of NEC. Appendectomy and sanitation of the abdominal cavity were carried out. The histological result confirmed gangrenous perforative appendicitis and purulent necrotic peritonitis. The postoperative course was unremarkable. The boy was transferred to the neonatology on day 33 of life and discharged home 12 days later. Despite of the low incidence of neonatal appendicitis, it should be taken into consideration if unclear abdominal symptoms occur in the neonatal period. Early surgical intervention contribute to a reduction of potential complications.

    Full Text Available Brain death (BD is the permanent and complete loss of cerebral and brainstem function. It is relatively uncommon in newborns with its percentage among deaths being 1-6.3%. BD leads to debate for medical, ethical and philosophical issues. It is a challenging condition in neonatal intensive care units (NICUs since difficulties for BD diagnosis in neonates and ever more so in preterm neonates do arise. Revised guidelines for BD diagnosis definition include history with known etiology, clinical examination, apnea testing and neurological evaluation often assisted by ancillary tests. We present the case of a near term female baby that was born with brain death due to hypoxic ischemic encephalopathy. We conclude that BD in newborns is a challenge to NICUs and there is a need for establishing and implementing new guidelines and checklists on national basis. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

    2016-04-01

    Antibiotics have not only saved lives and improved outcomes, but they also influence the evolving microbiome. This review summarizes reports on neonatal infections and variation in antibiotic utilization, discusses the emergence of resistant organisms, and presents data from human neonates and animal models demonstrating the impact of antibiotics on the microbiome, and how microbiome alterations impact health. The importance of antibiotic stewardship is also discussed. Infections increase neonatal morbidity and mortality. Furthermore, the clinical presentation of infections can be subtle, prompting clinicians to empirically start antibiotics when infection is a possibility. Antibiotic-resistant infections are a growing problem. Cohort studies have identified extensive center variations in antibiotic usage and associations between antibiotic exposures and outcomes. Studies of antibiotic-induced microbiome alterations and downstream effects on the developing immune system have increased our understanding of the mechanisms underlying the associations between antibiotics and adverse outcomes. The emergence of resistant microorganisms and recent evidence linking antibiotic practice variations with health outcomes has led to the initiation of antibiotic stewardship programs. The review encourages practitioners to assess local antibiotic use with regard to local microbiology, and to adopt steps to reduce infections and use antibiotics wisely.

    1992-01-01

    Full Text Available Malassezia furfur and Candida albicans are fungal pathogens which have been recognized with increasing frequency as agents of mortality and serious morbidity in neonatal intensive care unit patients. A longitudinal study of oral, rectal and umbilical colonization by these organisms of newborns admitted to a neonatal intensive care unit within 24 h of birth was undertaken. Of 71 infants followed for a minimum of 10 days, 24 were colonized with M furfur and 12 with C albicans during the first 10 days of life. The lower gastrointestinal tract was found to be the most common colonization site for both organisms. Statistically significant (P<0.05 inverse associations were demonstrated between gestational age and risk of colonization with either organism at any site, and between birthweight or gestational age and risk of rectal colonization with either organism. Antibiotics were associated with a relative risk colonization of 4.06 (P=0.06 with either organism at any site. It is concluded that M furfur and C albicans are common colonizing organisms in a neonatal intensive care unit setting and are most frequently harboured in the lower gastrointestinal tract. M furfur, recently implicated as a systemic pathogen in this population, has not been previously recognized as a gastrointestinal commensal organism. The relationship between colonization and invasive fungal disease, and potential roles for preventive strategies, remain to be elucidated.

    The prevalence of both childhood and adult obesity is rising in the developed world, and there is increasing interest in its underlying causes. A number of studies suggest a positive relationship between birth weight and childhood body mass index, but less is known about specific prenatal environmental influences on more direct measures of obesity. We used data from the Southampton Women's Survey to investigate parental influences on neonatal body composition ascertained by dual x-ray absorptiometry. Participating mothers were characterized in detail (anthropometry, lifestyle, diet) before and during pregnancy; information was also obtained on their partners. The offspring underwent assessment of fat and lean body mass by dual x-ray absorptiometry within 2 wk of birth. Linear regression methods were used to explore the parental determinants of neonatal body composition. Complete data were available for 448 mother-offspring pairs. Taller women and those with higher parity had offspring with increased birth weight, fat, and lean mass (P body fat at birth (all P Maternal size, parity, smoking history, walking speed, and fat stores are independent determinants of neonatal body composition. If these influences are shown to have persisting effects on body composition through to adulthood, they point to novel public health interventions early in life to prevent later obesity.

    This study reports the first case of symptomatic placental transfer of cryoglobulins and discusses the potential pathogenic processes and the basic guidelines for neonatal management. A 32-y-old woman was affected by essential type I cryoglobulinaemia and displayed the cold-triggered cutaneous symptoms of the disease due to a monoclonal immunoglobulin G (IgG) cryoglobulin. She gave birth to healthy dizygotic twins who were placed in incubators immediately after birth and did not show any cutaneous or visceral lesion in the first 2 d. Cyanotic macules appeared on the hand and foot of one of the newborns when they were removed from the incubators. The same monoclonal IgG-lambda cryoglobulin was identified in the two newborns' cord blood and in the mother's serum. The skin lesions disappeared within 1 wk as both twins were transiently replaced in incubators. No recurrence of skin lesions was observed even at room temperature and, 6 mo later, both twins were healthy and their clinical examination was normal. To the authors' knowledge, this is the first report of placental transfer of cryoglobulins and the first description of any neonatal effect. Neonates born to mothers suffering from IgG cryoglobulinaemia should be protected against cold to avoid precipitation of the pathogenic cryoglobulins, until spontaneous resolution.

    1982-11-01

    The local and systemic humoral immune responses to rotavirus were studied in six conventional neonatal calves. Attenuated bovine rotavirus was administered either orally or directly into an isolated intestinal loop. The parameters monitored were neutralizing rotavirus antibody in serum, immunofluorescent and neutralizing rotavirus antibody in intestinal loop washings, and rotavirus antibody-producing cells in intestinal mucosa. An antibody response was observed in the serum and intestinal secretions from one calf only. Viral replication was not detected in the isolated intestinal loop. Rotavirus antibody-producing cells were found in the intestinal mucosa of five calves. Double staining revealed that most of these cells produced antibody of the immunoglobulin A class. The conclusions were: (i) a previously described system to detect rotavirus antibody-producing cells can be used to study immune responses in neonatal calves, (ii) the class or subclass of antibody in rotavirus antibody-producing cells can be determined by double immunofluorescent staining, (iii) neonatal calves respond to rotavirus inoculation with a local immunoglobulin A response, and (iv) most of the rotavirus antibody-producing cells are located in the mucosa of the proximal small intestine.

    We reviewed 118 MR examinations in the neonatal period to define its indication, problem, and usefulness. The patients were 58 term infants under 28 days of age and 46 preterm infants under 46 week of their post conceptional age. Almost all patients were examined under sedation. We used pulse wave monitoring and respiration was monitored only by observing the chest motion. Hot water bags were used in some cases to keep the patient warm. No serious accidents or sequelae occurred, although a very few patients had a brief apnea attacks during sedation and some developed hypothermia after the examination. The MR provided many useful information such as basal ganglial lesions after perinatal asphyxia and multiplaner demonstration of the CN5 anomalies which no other modality could. The detection rate of abnormality in the study was about 65%. Although MR studies in the neonatal period have many difficulties to be overcome including sedation, maintenance of body temperature and monitoring, they can demonstrate useful information that are helpful for their early treatment and care. Thus we believe that the MR study should be performed in a more positive manner in a variety of clinical setting in the neonatal period. (author)

Most preterm infants exhibit recurrent apnea, resulting in repetitive oscillations in O(2) saturation (intermittent hypoxia, IH). Numerous factors are likely to play a role in the etiology of apnea including inputs from the carotid chemoreceptors. Despite major advances in our understanding of carotid chemoreceptor function in the early neonatal period, however, their contribution to the initiation of an apneic event and its eventual termination are still largely speculative. Recent findings have provided a detailed account of the postnatal changes in the incidence of hypoxemic events associated with apnea, and there is anecdotal evidence for a positive correlation with carotid chemoreceptor maturation. Furthermore, studies on non-human animal models have shown that chronic IH sensitizes the carotid chemoreceptors, which has been proposed to perpetuate the occurrence of apnea. An alternative hypothesis is that sensitization of the carotid chemoreceptors could represent an important protective mechanism to defend against severe hypoxemia. The purpose of this review, therefore, is to discuss how the carotid chemoreceptors may contribute to the initiation and termination of an apneic event in the neonate and the use of xanthine therapy in the prevention of apnea.

    We reviewed 118 MR examinations in the neonatal period to define its indication, problem, and usefulness. The patients were 58 term infants under 28 days of age and 46 preterm infants under 46 week of their post conceptional age. Almost all patients were examined under sedation. We used pulse wave monitoring and respiration was monitored only by observing the chest motion. Hot water bags were used in some cases to keep the patient warm. No serious accidents or sequelae occurred, although a very few patients had a brief apnea attacks during sedation and some developed hypothermia after the examination. The MR provided many useful information such as basal ganglial lesions after perinatal asphyxia and multiplaner demonstration of the CN5 anomalies which no other modality could. The detection rate of abnormality in the study was about 65%. Although MR studies in the neonatal period have many difficulties to be overcome including sedation, maintenance of body temperature and monitoring, they can demonstrate useful information that are helpful for their early treatment and care. Thus we believe that the MR study should be performed in a more positive manner in a variety of clinical setting in the neonatal period. (author).

    Cardiac ultrasounds (US) are not always available at the bedside. Cardiac Troponin I (cTnI), CK-MB and NT-proBNP may be an alternative or complementary to influence evaluation and treatment. To determine reference ranges of biochemical markers cTnI, CK-MB and NT-proBNP in normal neonates. Cord and blood samples were collected from neonates and the above biochemical markers were determined. Ultrasounds were performed blindly. CK-MB remains constant from cord blood to the first day, declining thereafter to almost half the values (81.5 vs 52.0 U/l); cTnI increases from 0.004 to 0.058 ng/ml by 72 h falling to 0.030 by day 10; NT-proBNP peaks by 24 h (5085.5 pg/ml), subsiding to 3388.5 pg/ml by day 3, falling to 1316.0 pg/ml by day 10. CK-MB, mostly of muscle origin and reflecting labor stress or injury, is not to recommend as a measure of myocardial damage in the neonate. The rise in cTnI may be explained by a degree of myocardial involvement, albeit physiological. The initial rise and subsequent fall of NT-proBNP represents the physiological ventricular overload of transient birth adaptation.

    Survival of extremely preterm and critically ill neonates has improved significantly over the last few decades following advances in neonatal intensive care. These include antenatal glucocorticoids, surfactant, continuous positive airway pressure support, advanced gentle modes of ventilation and inhaled nitric oxide. Probiotic supplementation is a recent significant milestone in the history of neonatal intensive care. Very few, if any, interventions match the ability of probiotics to significantly reduce the risk of death and definite necrotising enterocolitis while facilitating enteral feeds in high-risk preterm neonates. Probiotics also have a potential to benefit neonates with surgical conditions with significant gastrointestinal morbidity. Current evidence for the benefits of probiotic supplementation for neonates in an intensive care unit is reviewed. The mechanisms for the benefits of probiotics in this population are discussed, and guidelines for clinicians are provided in the context of the regulatory framework in Australia. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Neonatal sepsis is a major cause of morbidity and mortality in neonatal intensive care units. Treatment with antibiotics reduces mortality and morbidity, but neonatal sepsis remains a serious life-threatening condition. The objective of this study was to evaluate cognitive impairment in adult mice submitted to sepsis in the neonatal period. To this aim, 2-day-old male C57BL/6 mice were submitted to sepsis by injection of 25 μg of LPS. Sixty days after, the learning and memory were evaluated. It was observed that the mice submitted to neonatal sepsis presented impairment of habituation, aversive, and object recognition memories, and had an increase of immobility time in forced swimming test in adulthood. In conclusion, this study shows that the neonatal sepsis causes long-term brain alterations. These alterations can persist to adulthood in an animal model due to a vulnerability of the developing brain.

    Full Text Available Headed studs are nowadays the standard steel-concrete connectors because of their competitive advantages. Firstly, they provide a high degree of safety thanks to semiautomatic electric arc welding. These welds are not suitable for typical non-destructive tests. The analytical study comprises several models. The first vibration modes have been obtained. The experimental research has developed first the measurement of the natural frequencies of 28 headed-studs in the sonic range. Then they have been tested by non-destructive and destructive tests. Finally theirs tests have been compared with their respective frequency measurements. A clear relationship between the measured frequencies and the lack of penetration of the welds has been established, that confirms the analytical prediction of this effect of the internal weld imperfections. Therefore, the feasibility of simple and absolutely non-destructive tests of welded studs by in site measurement of natural frequencies in the sonic range has been clearly established in this work.

    Los pernos conectores aportan múltiples ventajas de uso, entre las que se encuentra el elevado margen de seguridad que ofrecen sus soldaduras ejecutadas mediante arco eléctrico. Estas soldaduras, aunque ampliamente fiables, son difícilmente comprobadas mediante ensayos no destructivos. El presente estudio plantea la inspección de soldaduras de pernos conectores mediante su espectro acústico. Analíticamente, la investigación se ha centrado en el cálculo de los primeros modos propios de vibración. Experimentalmente se han medido las frecuencias propias de resonancia de 28 pernos, en los que posteriormente se han llevado a cabo ensayos tanto no destructivos como destructivos. Se ha obtenido, tanto teórica como experimentalmente, una relación entre la frecuencia de vibración de los pernos conectores y la calidad de la soldadura. Por ello se verifica la posibilidad de inspección de estas

    Full Text Available Abstract Background Neonatal sepsis is a significant cause of morbidity and mortality in neonates. Appropriate clinical diagnosis and empirical treatment in a given setting is crucial as pathogens of bacterial sepsis and antibiotic sensitivity pattern can considerably vary in different settings. This study was conducted at Bugando Medical Centre (BMC, Tanzania to determine the prevalence of neonatal sepsis, predictors of positive blood culture, deaths and antimicrobial susceptibility, thus providing essential information to formulate a policy for management of neonatal sepsis. Methods This was a prospective cross sectional study involving 300 neonates admitted at BMC neonatal unit between March and November 2009. Standard data collection form was used to collect all demographic data and clinical characteristics of neonates. Blood culture was done on Brain Heart Infusion broth followed by identification of isolates using conventional methods and testing for their susceptibility to antimicrobial agents using the disc diffusion method. Results Among 770 neonates admitted during the study period; 300 (38.9% neonates were diagnosed to have neonatal sepsis by WHO criteria. Of 300 neonates with clinical neonatal sepsis 121(40% and 179(60% had early and late onset sepsis respectively. Positive blood culture was found in 57 (47.1% and 92 (51.4% among neonates with early and late onset neonatal sepsis respectively (p = 0.466. Predictors of positive blood culture in both early and late onset neonatal sepsis were inability to feed, lethargy, cyanosis, meconium stained liquor, premature rupture of the membrane and convulsion. About 49% of gram negatives isolates were resistant to third generation cephalosporins and 28% of Staphylococcus aureus were found to be Methicillin resistant Staphylococcus aureus (MRSA. Deaths occurred in 57 (19% of neonates. Factors that predicted deaths were positive blood culture (p = 0.0001, gram negative sepsis (p = 0.0001 and

    Full Text Available Background: This study aimed to determine neonatal nurses’ perceptions of knowledge and practice in pain management in NICUs & neonatal units. Methods: A cross-sectional descriptive study design was used. A total of 120 neonatal nurses who working in NICUs & neonatal units in Ardebil province, Iran were selected using the convenience sampling technique. A questionnaire of Nurses’ Perceptions of Neonatal Pain (Cong, 2013, including 36 questions with Likert scale and 2 open ended questions, was used. Data collected were analyzed with descriptive statistics of frequencies and percentages.Results: Nurses had Appropriate knowledge of neonatal pain management , but less than 50% felt that they received adequate training and continuing education on pain. Participants reported that they don’t use of pain assessment tools (65%. Less than half felt that the pain tool used in their unit was an accurate measure (44.2%. Fewer than half reported that pain was well managed (28.3% , that their pain protocols were research evidence based (34.2% and more than half reported that parents should be involve with the care and comfort of their infant during painful procedures (71.6%. Barriers to effective pain management emerged as high workload, shortage of personnel, lack of knowledge, absence of pain protocols, lack of time, and lack of trust in the pain assessment tools.Conclusions: proper pain management was significantly correlated with adequate training, use of proper and accurate pain tools, and clear and research-based protocols and parental involvement. It can be improved by developing guidelines and support of nurses, develop of clinically feasible pain tools, adequate training and proper supervision.

  19. Maternal haemoglobin and short-term neonatal outcome in preterm neonates.

    Full Text Available To determine whether there is a significant association between maternal haemoglobin measured before delivery and short-term neonatal outcome in very preterm neonates.We included prospectively all live births occurring from 25 to 32+6 weeks of gestation in a tertiary care centre between January 1(st 2009 and December 31(st 2011. Outborn infants and infants presenting with lethal malformations were excluded. Three hundred and thirty-nine mothers and 409 infants met the inclusion criteria. For each mother-infant pair a prospective record of epidemiologic data was performed and maternal haemoglobin concentration recorded within 24 hours before delivery was retrospectively researched. Maternal haemoglobin was divided into quartiles with the second and the third one regarded as reference as they were composed of normal haemoglobin values. Short-term outcome was defined as poor in case of death during hospital stay and/or grades III/IV intraventricular haemorrhage and/or periventricular leukomalacia and/or necessity of ventriculoperitoneal shunt.The global rate of poor short-term neonatal outcome was 11.4% and was significantly associated with low maternal haemoglobin values. This association remained significant after adjustment for antenatal corticosteroids therapy, gestational age, parity, mechanism of preterm birth, mode of delivery and birth weight (aOR = 2.97 CI 95% [1.36-6.47]. There was no relation between short-term neonatal outcome and high maternal haemoglobin concentration values.We show that low maternal haemoglobin concentration at delivery is an independent risk factor for poor short-term neonatal outcome in very preterm neonates. This study is one of the first to show such an association within the preterm population.

Non-availability of trained staff and infrastructure are the major recognized hurdles in the quality care of these neonates. Hourly progress growth charts and reports are still maintained manually by nurses along with continuous calculation of drug dosage and nutrition as per the changing weight of the baby. iNICU (integrated Neonatology Intensive Care Unit) leverages Beaglebone and Intel Edison based IoT integration with biomedical devices in NICU i.e. monitor, ventilator and blood gas machine. iNICU is hosted on IBM Softlayer based cloud computing infrastructure and map NICU workflow in Java based responsive web application to provide translational research informatics support to the clinicians. iNICU captures real time vital parameters i.e. respiration rate, heart rate, lab data and PACS amounting for millions of data points per day per child. Stream of data is sent to Apache Kafka layer which stores the same in Apache Cassandra NoSQL. iNICU also captures clinical data like feed intake, urine output, and daily assessment of child in PostgreSQL database. It acts as first Big Data hub (of both structured and unstructured data) of neonates across India offering temporal (longitudinal) data of their stay in NICU and allow clinicians in evaluating efficacy of their interventions. iNICU leverages drools based clinical rule based engine and deep learning based big data analytical model coded in R and PMML. iNICU solution aims to improve care time, fills skill gap, enable remote monitoring of neonates in rural regions, assists in identifying the early onset of disease, and reduction in neonatal mortality.
