    Neonatal sepsis is the most common cause of neonatal deaths with high mortality despite treatment. Neonatal sepsis can be classified into two subtypes depending upon onset of symptoms. There are many factors that make neonates more susceptable to infection. Signs of sepsis in neonates are often non-specific and high degree of suspicion is needed for early diagnosis. Some laboratory parameters can be helpful for screening of neonates with neonatal sepsis, but none of it is specific and sensitive enough to be used singly. Diagnostic approach mostly focuses on history and review of non specific signs and symptoms. Antibiotic treatment is the mainstay of treatment and supportive care is equally important. The aim of this review is to give an overview of neonatal sepsis, including incidence, etiology, clinical picture, diagnostics and therapy.

    Neonatal jaundice lasting greater than 2 weeks should be investigated. Pale stools and dark or yellow urine are evidence of liver disease, which should be urgently investigated. The neonatal hepatitis syndrome has many causes, and a structured approach to investigation is mandatory. It should be possible to confirm or exclude biliary atresia within one week, so that definitive surgery is not delayed unnecessarily. Babies with the neonatal hepatitis syndrome should have vigorous fat-soluble vitamin supplementation, including parenteral vitamin K if coagulation is abnormal. The prognosis for infants with idiopathic neonatal hepatitis and multifactorial cholestasis is excellent.

    Neonatal abstinence syndrome (NAS) is reaching epidemic proportions related to perinatal use of opioids. There are many approaches to assess and manage NAS, including one we have outlined. A standardized approach is likely to reduce length of stay and variability in practice. Circumcision is a frequent, painful procedure performed in the neonatal period. The rationale for providing analgesia is presented as well as a review of methods. Pharmacogenomics and pharmacogenetics have expanded our understanding of diseases and their drug therapy. Some applications of pharmacogenomics to the neonatal period are presented, along with pediatric challenges of developmental expression of drug-metabolizing enzymes.

    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.

    2013-01-01

    Cholestatic jaundice is a common presenting feature of neonatal hepatobiliary and metabolic dysfunction. Any infant who remains jaundiced beyond age 2 to 3 weeks should have the serum bilirubin level fractionated into a conjugated (direct) and unconjugated (indirect) portion. Conjugated hyperbilirubinemia is never physiologic or normal. The differential diagnosis of cholestasis is extensive, and a step-wise approach based on the initial history and physical examination is useful to rapidly identify the underlying etiology. Early recognition of neonatal cholestasis is essential to ensure timely treatment and optimal prognosis. Even when specific treatment is not available, infants who have cholestasis benefit from early medical management and optimization of nutrition. Future studies are necessary to determine the most reliable and cost-effective method of universal screening for neonatal cholestasis. PMID:24244109

    Neonatal sepsis continues to be a common and significant health care burden, especially in very-low-birth-weight infants (VLBW <1500 g). Though intrapartum antibiotic prophylaxis has decreased the incidence of early-onset group B streptococcal infection dramatically, it still remains a major cause of neonatal sepsis. Moreover, some studies among VLBW preterm infants have shown an increase in early-onset sepsis caused by Escherichia coli. As the signs and symptoms of neonatal sepsis are nonspecific, early diagnosis and prompt treatment remains a challenge. There have been a myriad of studies on various diagnostic markers like hematological indices, acute phase reactants, C-reactive protein, procalcitonin, cytokines, and cell surface markers among others. Nonetheless, further research is needed to identify a biomarker with high diagnostic accuracy and validity. Some of the newer markers like inter α inhibitor proteins have shown promising results thereby potentially aiding in early detection of neonates with sepsis. In order to decrease the widespread, prolonged use of unnecessary antibiotics and improve the outcome of the infants with sepsis, reliable identification of sepsis at an earlier stage is paramount.

    Intussusception in infants and young children is a relatively common entity with a well defined clinical picture and a favorable outcome in most cases.The neonatal intussusceptions is extremely rare and does not have a well-defined clinical picture since its clinical manifestations vary according to the gestational time it occurs, the response of the injured intestine and the gestational age of the child concerned. Two new cases of neonatal intussusceptions are presented and a review of the world literature is performed. Given the stage of intussusceptions (pre- or postnatal) occurs and gestational age of the affected infant (preterm or term), there are three entities with clinical characteristics, topography and evolution rather different: prenatal or intrauterine intussusception, postnatal intussusception in the preterm and postnatal intussusception in the term infant.

    2013-12-01

    Neonatal hemochromatosis is a clinical condition in which severe liver disease in the newborn is accompanied by extrahepatic siderosis. Gestational alloimmune liver disease (GALD) has been established as the cause of fetal liver injury resulting in nearly all cases of NH. In GALD, a women is exposed to a fetal antigen that she does not recognize as "self" and subsequently begins to produce IgG antibodies that are directed against fetal hepatocytes. These antibodies bind to fetal liver antigen and activate the terminal complement cascade resulting in hepatocyte injury and death. GALD can cause congenital cirrhosis or acute liver failure with and without iron overload and siderosis. Practitioners should consider GALD in cases of fetal demise, stillbirth, and neonatal acute liver failure. Identification of infants with GALD is important as treatment is available and effective for subsequent pregnancies.

    An otherwise healthy 5-week-old infant with erythematous plaques predominantly on the face and scalp presented to our dermatology clinic. The mother had been diagnosed with lupus erythematosus 2 years earlier but her disease was quiescent. Neonatal lupus is a rare condition associated with transplacental transfer of IgG anti-SSA/Ro and anti-SSB/La antibodies from the mother to the fetus. Active connective tissue disease in the mother does not have to be present and in fact is often absent. Although the cutaneous, hematologic and hepatic manifestations are transient, the potential for permanent heart block makes it necessary for this to be carefully ruled out. As in this case, the dermatologist may be the one to make the diagnosis and should be aware of the clinical presentation, work-up, and management of this important disease.

    At birth approximately 10 % of term or near-term neonates require initial stabilization maneuvers to establish a cry or regular breathing, maintain a heart rate greater than 100 beats per minute (bpm), and good color and muscular tone. About 1 % requires ventilation and very few infants receive chest compressions or medication. However, birth asphyxia is a worldwide problem and can lead to death or serious sequelae. Recently, the European Resuscitation Council (ERC) and the International Liaison Committee on Resuscitation (ILCOR) published new guidelines on resuscitation at birth. These guidelines review specific questions such as the use of air or 100 % oxygen in the delivery room, dose and routes of adrenaline delivery, the peripartum management of meconium-stained amniotic fluid, and temperature control. Assisted ventilation in preterm infants is briefly described. New devices to improve the care of newborn infants, such as the laryngeal mask airway or CO2 detectors to confirm tracheal tube placement, are also discussed. Significant changes have occurred in some practices and are included in this document.

    In recent years, there have been significant advancements in our understanding of acute kidney injury (AKI) and its impact on outcomes across medicine. Research based on single-center cohorts suggests that neonatal AKI is very common and associated with poor outcomes. In this state-of-the-art review on neonatal AKI, we highlight the unique aspects of neonatal renal physiology, definition, risk factors, epidemiology, outcomes, evaluation, and management of AKI in neonates. The changes in renal function with gestational and chronologic age are described. We put forth and describe the neonatal modified Kidney Diseases: Improving Global Outcomes AKI criteria and provide the rationale for its use as the standardized definition of neonatal AKI. We discuss risk factors for neonatal AKI and suggest which patient populations may warrant closer surveillance, including neonates <1500 g, infants who experience perinatal asphyxia, near term/ term infants with low Apgar scores, those treated with extracorporeal membrane oxygenation, and those requiring cardiac surgery. We provide recommendations for the evaluation and treatment of these patients, including medications and renal replacement therapies. We discuss the need for long-term follow-up of neonates with AKI to identify those children who will go on to develop chronic kidney disease. This review highlights the deficits in our understanding of neonatal AKI that require further investigation. In an effort to begin to address these needs, the Neonatal Kidney Collaborative was formed in 2014 with the goal of better understanding neonatal AKI, beginning to answer critical questions, and improving outcomes in these vulnerable populations.

    2015-01-01

    Neonates have little immunological memory and a developing immune system, which increases their vulnerability to infectious agents. Recent advances in understanding of neonatal immunity indicate that both innate and adaptive responses are dependent on precursor frequency of lymphocytes, antigenic dose and mode of exposure. Studies in neonatal mouse models and human umbilical cord blood cells demonstrate the capability of neonatal immune cells to produce immune responses similar to adults in some aspects but not others. This review focuses mainly on the developmental and functional mechanisms of the human neonatal immune system. In particular, the mechanism of innate and adaptive immunity and the role of neutrophils, antigen presenting cells, differences in subclasses of T lymphocytes (Th1, Th2, Tregs) and B cells are discussed. In addition, we have included the recent developments in neonatal mouse immune system. Understanding neonatal immunity is essential to development of therapeutic vaccines to combat newly emerging infectious agents. PMID:25088080

    Neonatal septic arthritis has always been considered as separate from its counterpart in older children. The condition is uncommon but serious. Affected neonates usually survive, but with permanent skeletal deformities. Ten cases of neonatal septic arthritis were diagnosed between January 1989 and December 1993 in the neonatal intensive care units of two referral hospitals in the state of Kelantan, Malaysia. All except one neonate was born prematurely. The mean age of presentation was 15.6 days. Joint swelling (10/10), increased warmth (7/10) and erythema of the overlying skin (7/10) were the common presenting signs. Vague constitutional symptoms preceded the definitive signs of septic arthritis in all cases. The total white cell counts were raised with shift to the left. The knee (60%) was not commonly affected, followed by the hip (13%) and ankle (13%). Three neonates had multiple joint involvement. Coexistence of arthritis with osteomyelitis was observed in seven neonates. The commonest organism isolated was methicillin resistant Staphylococcus aureus (9/10). Needle aspiration was performed in nine neonates and one had incision with drainage. Follow up data was available for five neonates and two of these had skeletal morbidity. Early diagnosis by frequent examination of the joints, prompt treatment and control of nosocomial infection are important for management.

    2004-05-01

    Multiple lines of evidence suggest an increased sensitivity to pain in neonates. Repeated and prolonged pain exposure may affect the subsequent development of pain systems, as well as potentially contribute to alterations in long-term development and behavior. Despite impressive gains in the knowledge of neonatal pain mechanisms and strategies to treat neonatal pain acquired during the last 15 years, a large gap still exists between routine clinical practice and research results. Accurate assessment of pain is crucial for effective pain management in neonates. Neonatal pain management should rely on current scientific evidence more than the attitudes and beliefs of care-givers. Parents should be informed of pain relief strategies and their participation in the health care plan to alleviate pain should be encouraged. The need for systemic analgesia for both moderate and severe pain, in conjunction with behavioral/environmental approaches to pain management, is emphasized. A main sources of pain in the neonate is procedural pain which should always be prevented and treated. Nonpharmacological approaches constitute important treatment options for managing procedural pain. Nonpharmacological interventions (environmental and preventive measures, non-nutritive sucking, sweet solutions, skin-skin contact, and breastfeeding analgesia) can reduce neonatal pain indirectly by reducing the total amount of noxious stimuli to which infants are exposed, and directly, by blocking nociceptive transduction or transmission or by activation of descending inhibitory pathways or by activating attention and arousal systems that modulate pain. Opioids are the mainstay of pharmacological pain treatment but there are other useful medications and techniques that may be used for pain relief. National guidelines are necessary to improve neonatal pain management at the institutional level, individual neonatal intensive care units need to develop specific practice guidelines regarding pain

    Neonatal electroencephalography (EEG) presents some of the most difficult challenges in EEG interpretation. It differs significantly in many ways from EEG of older children and adults. Technologically, acquisition of a neonatal EEG is significantly more difficult and different than an adult EEG. There are numerous features that are age-specific and change almost week-to-week in the preterm infant. Some features may be normal at one age and abnormal if they persist for several weeks. Many of these features also have different implications in neonates as compared to older individuals. These issues mandate a different approach to neonatal EEG interpretation. In this article an overview of neonatal EEG is presented. After a brief discussion of relevant technical issues, various normal EEG features encountered in neonates are discussed. This is followed by a discussion of the ontogeny of EEG, starting from the age of viability to the first few months of life. A description of various abnormalities follows. Finally, an approach to analysis of a neonatal EEG is presented.

    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.

  6. Neonatal hepatitis syndrome.

    PubMed

    Roberts, Eve A

    2003-10-01

    Conjugated hyperbilirubinaemia in an infant indicates neonatal liver disease. This neonatal hepatitis syndrome has numerous possible causes, classified as infective, anatomic/structural, metabolic, genetic, neoplastic, vascular, toxic, immune and idiopathic. Any infant who is jaundiced at 2-4 weeks old needs to have the serum conjugated bilirubin measured, even if he/she looks otherwise well. If conjugated hyperbilirubinaemia is present, a methodical and comprehensive diagnostic investigation should be performed. Early diagnosis is critical for the best outcome. In particular, palliative surgery for extrahepatic biliary atresia has the best chance of success if performed before the infant is 8 weeks old. Definitive treatments available for many causes of neonatal hepatitis syndrome should be started as soon as possible. Alternatively, liver transplantation may be life saving. Supportive care, especially with attention to nutritional needs, is important for all infants with neonatal hepatitis syndrome.

    Probe tones from 220 Hz to 2 000 Hz were used to measure the static and dynamic acoustic impedance of 44 neonates. Acoustic reflex thresholds to broad band noise were obtained from every neonate tested when employing the higher frequency probe tones. The reflex threshold levels measured are similar to those of adults. The static impedance values are discussed to give a possible explanation of why reflex thresholds cannot be detected using conventional 220 Hz impedance bridges.

    Nine cases of neonatal Haemophilus influenzae septicaemia were recorded in Finland during 1985-9; incidence was 2.8/100,000 live births, and 1.6% of all cases of neonatal septicaemia. The onset of the disease was early in all cases, ranging from 0-6 hours after delivery. Seven of the infants were preterm and three died (overall mortality 33%). H influenzae was isolated from blood in seven of the cases, and in two neonates with clinical signs of septicaemia it was found on several surface sites and the placenta. One of the eight strains of H influenzae was capsular type b and biotype I, the rest being non-typable--a distribution similar to those previously reported. Four of the uncapsulated strains were of biotype III, and three were of biotype II. None of the strains of H influenzae was of biotype IV, which has been reported to be characteristic of neonatal and genital isolates of H influenzae. All nine mothers had some sign of infection at the time of or shortly after delivery. H influenzae was isolated from five mothers: from the blood (n = 1) or from the placenta or cervix (n = 4). The use of intrauterine devices may be a possible risk factor for neonatal H influenzae infections; two of the mothers had such devices in place during their pregnancies. PMID:2025040

    2013-08-01

    Neonatal seizures are a neurological emergency and prompt treatment is required. Seizure burden in neonates can be very high, status epilepticus a frequent occurrence, and the majority of seizures do not have any clinical correlate. Detection of neonatal seizures is only possible with continuous electroencephalogram (EEG) monitoring. EEG interpretation requires special expertise that is not available in most neonatal intensive care units (NICUs). As a result, a simplified method of EEG recording incorporating an easy-to-interpret compressed trend of the EEG output (amplitude integrated EEG) from one of the EEG output from one or two channels has emerged as a popular way to monitor neurological function in the NICU. This is not without limitations; short duration and low amplitude seizures can be missed, artefacts are problematic and may mimic seizure-like activity and only a restricted area of the brain is monitored. Continuous multichannel EEG is the gold standard for detecting seizures and monitoring response to therapy but expert interpretation of the EEG output is generally not available. Some centres have set up remote access for neurophysiologists to the cot-side EEG, but reliable interpretation is wholly dependent on the 24 h availability of experts, an expensive solution. A more practical solution for the NICU without such expertise is an automated seizure detection system. This review outlines the current state of the art regarding cot-side monitoring of neonatal seizures in the NICU.

    2016-01-01

    Purpose of the review Although infection rates have modestly decreased in the neonatal intensive care unit (NICU) as a result of ongoing quality improvement measures, neonatal sepsis remains a frequent and devastating problem among hospitalized preterm neonates. Despite multiple attempts to address this unmet need, there have been minimal advances in clinical management, outcomes, and accuracy of diagnostic testing options over the last three decades. One strong contributor to a lack of medical progress is a variable case definition of disease. The inability to agree on a precise definition greatly reduces the likelihood of aligning findings from epidemiologists, clinicians, and researchers, which, in turn, severely hinders progress towards improving outcomes. Recent findings Pediatric consensus definitions for sepsis are not accurate in term infants and are not appropriate for preterm infants. In contrast to the defined multi-stage criteria for other devastating diseases encountered in the NICU (e.g., bronchopulmonary dysplasia), there is significant variability in the criteria used by investigators to substantiate the diagnosis of neonatal sepsis. Summary The lack of an accepted consensus definition for neonatal sepsis impedes our efforts towards improved diagnostic and prognostic options as well as accurate outcomes information for this vulnerable population.

    Discovery of scrotal swelling in a neonate can be a source of anxiety for parents, clinicians, and sonologists alike. This pictorial essay provides a focused review of commonly encountered scrotal masses and mimics specific to the neonatal setting. Although malignancy is a concern, it is very uncommon, as most neonatal scrotal masses are benign. Key discriminating features and management options are highlighted to improve the radiologist’s ability to diagnose neonatal scrotal conditions and guide treatment decisions. Neonatal scrotal processes ranging from common to uncommon will be discussed. PMID:25715370

    This review deals with early neonatal medicine and its rapid development as a medical specialty, starting with the birth of neonatology in the early 19th century. Shaffer first used the term neonatology in 1963 to cover neonatal disorders and their treatment. Between the early 19th century and the 1950s, neonatal care was ensured by obstetricians, whose main goal was to reduce neonatal mortality. After the second world war, and especially the 1960s, the development of neonatal physiology and pathophysiology provided insights into neonatal diseases and their treatment, including respiratory distress, jaundice, malnutrition, and prevention of respiratory distress and brain complications, etc. Currently, neonatal mortality, regardless of birth weight, is below 2/1000, and the survival rate of premature infants, regardless of gestational age and birth weight, exceeds 85%. This represents a resounding success, despite the associated costs, ethical issues, and inevitable morbidity.

    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.

  17. Maternal, neonatal and community factors influencing neonatal mortality in Brazil.

    Child mortality (the mortality of children less than five years old) declined considerably in the developing world in the 1990s, but infant mortality declined less. The reductions in neonatal mortality were not impressive and, as a consequence, there is an increasing percentage of infant deaths in the neonatal period. Any further reduction in child mortality, therefore, requires an understanding of the determinants of neonatal mortality. 209,628 birth and 2581 neonatal death records for the 1998 birth cohort from the city of São Paulo, Brazil, were probabilistically matched. Data were from SINASC and SIM, Information Systems on Live Births and Deaths of Brazil. Logistic regression was used to find the association between neonatal mortality and the following risk factors: birth weight, gestational age, Apgar scores at 1 and 5 minutes, delivery mode, plurality, sex, maternal education, maternal age, number of prior losses, prenatal care, race, parity and community development. Infants of older mothers were less likely to die in the neonatal period. Caesarean delivery was not found to be associated with neonatal mortality. Low birth weight, pre-term birth and low Apgar scores were associated with neonatal death. Having a mother who lives in the highest developed community decreased the odds of neonatal death, suggesting that factors not measured in this study are behind such association. This result may also indicate that other factors over and above biological and more proximate factors could affect neonatal death.

    Neonatal thyroid storm is rare; the diagnostic criteria and management of neonatal thyroid storm have not been well established. In this paper, we report a preterm infant diagnosed with neonatal hyperthyroidism secondary to maternal Graves' disease who was discharged after therapy. Unfortunately, he was rehospitalised for neonatal thyroid storm. We will discuss the diagnosis and general therapy of neonatal thyroid storm.

    To assess and correlate the microbiology of neonatal septic arthritis with the clinical presentation, we reviewed the records of nine infants with neonatal septic arthritis (NSA) diagnosed at Edmonton hospitals between 1964 and 1981, and evaluated 92 other cases reported in the English literature since 1960. Our analysis revealed that the microbiology of NSA seemed to be dependent on whether it was hospital or community acquired. In the hospital-acquired cases, staphylococci were the predominant isolates (62%), followed by Candida species (17%) and gram-negative enteric bacilli (15%). Community-acquired arthritis was caused most often by streptococci (52%), followed by staphylococci (26%) and gonococci (17%). Since 1970, the relative infrequency of staphylococcal (5%) in favor of streptococcal (75%) isolates in community-acquired NSA is even more pronounced.

    Neonatal lupus has a rare incidence, distinct from systemic lupus erythematosus. This is an acquired autoimmune disease associated with maternal antibodies to proteins Ro / La (SSA /SSB), transferred by the placenta; it represents the prototype of passive transfer of antibodies from mother to child. The disease can affect the skin, heart, and rarely, the hepatobiliary or hematologic systems. Congenital complete heart block is the most severe form of neonatal lupus. In clinical practice it is important to distinguish in utero a complete from an incomplete atrioventricular block (AV) in order to render prompt care. We present the case of a new born female, who was diagnosed with an atrio-ventricular block at 26 weeksí gestation. When the baby was delivered at 38 weeksí gestation, she presented bradycardia (54 xí). On the suspicion of neonatal lupus, we required antinuclear antibodies, anti-Sm, anti-RNP, anti-SS-A and anti-SS-B, which were positive. A bicameral pacemaker was placed uneventfully.

    Partial exchange transfusion (PET) is traditionally suggested as treatment for neonates diagnosed with polycythemia. Nevertheless, justification of this treatment is controversial. We evaluated the risk for short-term complications associated with a restrictive treatment protocol for neonatal polycythemia. A retrospective cross-sectional analytical study was conducted. Three treatment groups were defined and managed according to their degree of polycythemia, defined by capillary tube filled with venous blood and manually centrifuged hematocrit: group 1, hematocrit 65 to 69% and no special treatment was recommended; group 2, hematocrit 70 to 75% and intravenous fluids were given and feedings were withheld until hematocrit decreased to < 70%; and group 3, hematocrit ≥ 76% or symptomatic neonates and PET was recommended. During the study period, 190 neonates were diagnosed with polycythemia. The overall rate of short-term complications was 15% (28 neonates). Seizures, proven necrotizing enterocolitis, or thrombosis did not occur in any participating neonates. PET was performed in 31 (16%) neonates. The groups did not differ in their rate of early neonatal morbidities or length of hospitalization. Restrictive treatment for neonatal asymptomatic polycythemia is not associated with an increased risk of short-term complications.

    Neonatal herpes simplex virus infections are uncommon, but because of the morbidity and mortality associated with the infection they are often considered in the differential diagnosis of ill neonates. The use of polymerase chain reaction for diagnosis of central nervous system infections and the development of safe and effective antiviral therapy has revolutionized the diagnosis and management of these infants. Initiation of long-term antiviral suppressive therapy in these infants has led to significant improvement in morbidity. This article summarizes the epidemiology of neonatal herpes simplex virus infections and discusses clinical presentation, diagnosis, management, and follow up of infants with neonatal herpes disease.

    In the United Kingdom, newborn assessment incorporates a screening eye examination for any structural abnormalities, observation of neonate's visual behaviour and direct ophthalmoscopy examination looking for red reflex. Early identification and immediate management of eye related pathologies should commence soon after birth as early diagnosis and prompt intervention may have significant impact on the prognosis for many potentially blinding but treatable disorders such as congenital cataracts and retinoblastoma. If left undetected and untreated, such problems may potentially lead to irreversible damage to the vision which persists into adulthood resulting in lack of self-confidence together with difficulties in educational attainment and job opportunities.

    Maternal use of certain drugs during pregnancy can result in transient neonatal signs consistent with withdrawal or acute toxicity or cause sustained signs consistent with a lasting drug effect. In addition, hospitalized infants who are treated with opioids or benzodiazepines to provide analgesia or sedation may be at risk for manifesting signs of withdrawal. This statement updates information about the clinical presentation of infants exposed to intrauterine drugs and the therapeutic options for treatment of withdrawal and is expanded to include evidence-based approaches to the management of the hospitalized infant who requires weaning from analgesics or sedatives.

    Aims and Objectives: Evaluation of neonatal hypernatremia and hypernatremic dehydration in neonates receiving exclusive breastfeeding. Introduction: Neonatal hypernatremia is a serious condition in the newborn period. We present infants with hypernatremic dehydration due to breast milk (BM) hypernatremia. Hypernatremic dehydration in breast-fed newborns is usually secondary to insufficient lactation. We present the neonatal hypernatremia and hypernatremic dehydration encountered between January and December, 2012, its causes and treatment. Methodology: This was a retrospective study. We analyzed records of babies admitted to the Neonatal Intensive Care Unit who were investigated and found to have hypernatremia and whose mother's BM sodium (BM Na) was done. Inclusion Criteria: (1) Babies with serum Na >145 meq/l, (2) euglycemia, (3) normocalcemic, (4) no clinical and lab evidence of sepsis, (5) exclusive breast feeds. Exclusion Criteria: Neonates not satisfying any mentioned criterion. Results: BM Na correlated strongly with neonatal hypernatremia in exclusively breast-fed babies who did not otherwise have any risk factor. Conclusion: Elevated BM Na is an important etiological factor in neonatal hypernatremia. PMID:28197048

    A term neonate was born with a grossly swollen and discoloured left hand and forearm. He was transferred from the local hospital to the plastic surgical unit, where a diagnosis of compartment syndrome was made and he underwent emergency forearm fasciotomies at six hours of age. Following serial debridements of necrotic tissue, he underwent split-thickness skin grafting of the resultant defects of his forearm, hand and digits. At the clinic follow-up appointment two months after the procedure, he was found to have developed severe flexion contractures despite regular outpatient hand therapy and splintage. He has had further reconstruction with contracture release, use of artificial dermal matrix, and K-wire fixation of the thumb and wrist. Despite this, the long term outcome is likely to be an arm with poor function. The key learning point from this case is that despite prompt transfer, diagnosis and appropriate surgical management, the outcome for neonatal compartment syndrome may still be poor. PMID:27138850

    Neonatal conjunctivitis is the most common occular disease in neonates. Most infections are acquired during vaginal delivery. In spite most of these cases are benign; some of them may progress to systemic complications like loss of vision if left untreated. The authors present a case of a newborn who developed late onset neonatal sepsis from E. coli positive conjunctivitis. The baby was treated with Injection Meropenem and Injection Amikacin for 10 days. The course was uneventful, after that baby responded well and discharged home on 24th day.

    The aim of this study is to determine the oxidative state of term and preterm neonates at the moment of birth and during the first days of life, and the influence of exposure to oxygen on the premature neonates.A total of 20 neonates were selected. Group A: 10 healthy full-term neonates, and Group B: 10 preterm neonates with no other pathology associated, requiring oxygen therapy. Venous samples were taken in cord at 3 and 72 h in Group A, and in cord at 3, 24 and 72 h and 7 days in Group B.Hydroperoxides, Q10 coenzyme (Co Q10) and alpha-tocopherol were measured within the erythrocyte membrane. Levels of hydroperoxides present in erythrocyte membrane were higher than normal both in Group A and in Group B at birth. This increase was greater in the group of premature neonates. Levels of alpha-tocopherol at birth increase significantly at 72 h in term neonates. Among the premature newborns, alpha-tocopherol levels are two to three times lower at birth and do not rise to higher levels as in the term neonate group. Fall in levels of Co Q10 in erythrocyte membranes is observed, and perhaps is due to the role of Co Q10 in maintaining the pool of reduced tocopherol. At birth, the neonate presents an increase of markers of oxidative stress and a decrease of their antioxidant defenses. This difference is greater as gestational age decreases. The application of oxygen therapy resulted in these levels which remain low throughout the study period.

    As more critically ill term and premature neonates are surviving their acute illness, their long-term neurodevelopmental morbidity is being recognized. Continuous monitoring of cerebral function, with electroencephalography or derived digital trends, can provide key information regarding seizures and background patterns, with direct treatment and prognostic implications. Conventional video-electroencephalography remains the gold standard for neonatal seizure diagnosis and quantification, but can be supplemented by digital trending modalities. Both conventional and amplitude-integrated electroencephalography can provide valuable data regarding the background trends. This review describes indications and methods for continuous electroencephalography monitoring in high-risk neonates.

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

    Neonatal herpes, seen roughly in 1 of 3000 live births in the United States, is the most serious manifestation of herpes simplex virus (HSV) infection in the perinatal period. Although acyclovir therapy decreases infant mortality associated with perinatal HSV transmission, development of permanent neurological disabilities is not uncommon. Mother-to-neonate HSV transmission is most efficient when maternal genital tract HSV infection is acquired proximate to the time of delivery, signifying that neonatal herpes prevention strategies need to focus on decreasing the incidence of maternal infection during pregnancy and more precisely identifying infants most likely to benefit from prophylactic antiviral therapy.

    An explosion of work over the last decade has produced insight into the multiple hereditary causes of a nonimmunological form of diabetes diagnosed most frequently within the first 6 months of life. These studies are providing increased understanding of genes involved in the entire chain of steps that control glucose homeostasis. Neonatal diabetes is now understood to arise from mutations in genes that play critical roles in the development of the pancreas, of β-cell apoptosis and insulin processing, as well as the regulation of insulin release. For the basic researcher, this work is providing novel tools to explore fundamental molecular and cellular processes. For the clinician, these studies underscore the need to identify the genetic cause underlying each case. It is increasingly clear that the prognosis, therapeutic approach, and genetic counseling a physician provides must be tailored to a specific gene in order to provide the best medical care.

    The neonatal lupus syndromes (NLS), while quite rare, carry significant mortality and morbidity in cases of cardiac manifestations. Although anti-SSA/Ro-SSB/La antibodies are detected in > 85% of mothers whose fetuses are identified with congenital heart block (CHB) in a structurally normal heart, when clinicians applied this testing to their pregnant patients, the risk for a woman with the candidate antibodies to have a child with CHB was at or below 1 in 50. While the precise pathogenic mechanism of antibody-mediated injury remains unknown, it is clear that the antibodies alone are insufficient to cause disease and fetal factors are likely contributory. In vivo and in vitro evidence supports a pathologic cascade involving apoptosis of cardiocytes, surface translocation of Ro and La antigens, binding of maternal autoantibodies, secretion of profibrosing factors (e.g., TGFbeta) from the scavenging macrophages and modulation of cardiac fibroblasts to a myofibroflast scarring phenotype. The spectrum of cardiac abnormalities continues to expand, with varying degrees of block identified in utero and reports of late onset cardiomyopathy (some of which display endocardial fibroelastosis). Moreover, there is now clear documentation that incomplete blocks (including those improving in utero with dexamethasone) can progress postnatally, despite the clearance of the maternal antibodies from the neonatal circulation. Better echocardiographic measurements which identify first degree block in utero may be the optimal means of approaching pregnant women at risk. Prophylactic therapies, including treatment with intravenous immunoglobulin, await larger trials. In order to achieve advances at both the bench and bedside, national research registries established in the US and Canada are critical.

    We aimed to characterize the parent experience of caring for an infant with neonatal encephalopathy. In this mixed-methods study, we performed semistructured interviews with parents whose infants were enrolled in an existing longitudinal cohort study of therapeutic hypothermia between 2011 and 2014. Thematic saturation was achieved after 20 interviews. Parent experience of caring for a child with neonatal encephalopathy was characterized by 3 principal themes. Theme 1: Many families described cumulative loss and grief throughout the perinatal crisis, critical neonatal course, and subsequent missed developmental milestones. Theme 2: Families experienced entangled infant and broader family interests. Theme 3: Parents evolved into and found meaning in their role as an advocate. These data offer insight into the lived experience of parenting an infant with neonatal encephalopathy. Primary data from parents can serve as a useful framework to guide the development and interpretation of parent-centered outcomes.

    Serum immunoglobulins G, M and A levels were studied in 187 Nigerian neonates. Estimations were done by the radial immunodifusion method of Mancini. Immunoglobulin G shows a fall in value in the first few days of life to about 62% of the value in the last days of the neonatal period. There is however a gradual increase in the level of IgM to about double at the end of the neonatal period. IgA level remained relatively constantly low throughout this period. The effect of maternal education on the levels of immunoglobulins of their neonates was also investigated. This had a positive influence at the secondary educational level, affecting only the IgG and IgA.

    Neonatal sepsis is a major cause of morbidity and mortality and its signs and symptoms are nonspecific, which makes the diagnosis difficult. The routinely used laboratory tests are not effective methods of analysis, as they are extremely nonspecific and often cause inappropriate use of antibiotics. Sepsis is the result of an infection associated with a systemic inflammatory response with production and release of a wide range of inflammatory mediators. Cytokines are potent inflammatory mediators and their serum levels are increased during infections, so changes from other inflammatory effector molecules may occur. Although proinflammatory and anti-inflammatory cytokines have been identified as probable markers of neonatal infection, in order to characterize the inflammatory response during sepsis, it is necessary to analyze a panel of cytokines and not only the measurement of individual cytokines. Measurements of inflammatory mediators bring new options for diagnosing and following up neonatal sepsis, thus enabling early treatment and, as a result, increased neonatal survival. By taking into account the magnitude of neonatal sepsis, the aim of this review is to address the role of cytokines in the pathogenesis of neonatal sepsis and its value as a diagnostic criterion.

    Neonatal haemochromatosis is a rare alloimmune gestational disease with a high mortality. The hallmark of neonatal haemochromatosis is severe neonatal liver failure associated with extrahepatic siderosis. Thus far, no pituitary dysfunction has been reported to result from the tissue damage associated with extrahepatic siderosis. The present report describes a neonate with neonatal haemochromatosis and secondary hypothyroidism associated with pituitary iron deposition. Both the conditions were successfully treated by ABO-incompatible liver transplantation. Pituitary gland dysfunction is another possible extrahepatic manifestation of neonatal haemochromatosis, and it is reversible after liver transplantation.

    PubMed

    Stronati, M; Decembrino, L

    2006-12-01

    Over the last two decades, systemic fungal infections have emerged to play a primary role in hospital-acquired infections. C. albicans is involved in 75% of neonatal candidiasis; however, the incidence of infection from C. parapsilosis is also increasing significantly. The higher incidence observed in the high-risk group of very low birth weight (VLBW) infants is linked to their special physical characteristics and the diagnostic and therapeutic invasive procedures they undergo. Colonization is a relevant risk factor depending on the colonized site , the fungal species and the type of colonization. Serological tests have a low specificity and sensitivity; in many cases, they do not distinguish between colonization and infection. Blood culture, although the best diagnostic test for determining systemic infection, can result negative, even in cases of deep organ involvement. In addition, fungi grow more slowly than bacteria in cultures. So, the difficulty in diagnosing systemic candidiasis and its aspecific clinical features may make empirical therapy appropriate. Amphotericin B (AmB) alone or combined with 5-fluorocytosine remains the drug of choice. Fluconazole represents a valid alternative. Recently developed new formulations of amphotericin incapsulated in liposomes can avoid possible adverse effects. Prognosis depends on the specific micro-organism involved; mortality is higher in the presence of C. albicans. As prognosis is associated with high mortality, prevention measures to reduce risk factors are of critical importance.

    Neonatal lupus continues to generate considerable interest despite its rarity; more than 15 original contributions were made to the literature in the past year. Diverse aspects of this "syndrome" of passively acquired autoimmunity have been covered. Experiments using a rabbit model provided insights into the pathogenicity of maternal anti-Ro/SS-A and anti-La/SS-B antibodies. Perfusion of rabbit hearts with anti-Ro/SS-A and anti-La/SS-B sera resulted in conduction abnormalities in whole adult rabbit hearts and induced a reduction in the peak slow inward current in patch-clamp experiments of isolated rabbit ventricular myocytes, suggesting involvement of calcium channels. Clinical investigations are moving away from case reports, and recent studies now include substantial entries. Assuming that patients reported from the United States, Finland, and England are all separate, sera from at least 100 different mothers of infants with congenital heart block have been studied. Although there is apparently no serologic profile that is unique to mothers of affected children, compared with mothers of healthy children, anti-Ro/SS-A antibodies (anti-52-kD antibodies are more prevalent by immunoblot in congenital heart block, although all these sera are likely to have anti-60-kD antibodies by immunoprecipitation) are usually of high titer and associated with anti-La/SS-B antibodies. To date, the only maternal autoantibodies that have been associated with congenital heart block recognize Ro/SS-A or La/SS-B antigens. Mothers of affected infants are often asymptomatic, and when symptomatic, the clinical features are frequently characteristic of Sjögren's syndrome. Although treatment of affected fetuses with dexamethasone has successfully diminished associated effusions, there has been no report of reversal of established third-degree heart block.

    Neonatal jaundice is a common condition that occurs in newborn infants in the first week of life. Today, techniques used for detection are required blood samples and other clinical testing with special equipment. The aim of this study is creating a non-invasive system to control and to detect the jaundice periodically and helping doctors for early diagnosis. In this work, first, a patient group which is consisted from jaundiced babies and a control group which is consisted from healthy babies are prepared, then between 24 and 48 h after birth, 40 jaundiced and 40 healthy newborns are chosen. Second, advanced image processing techniques are used on the images which are taken with a standard smartphone and the color calibration card. Segmentation, pixel similarity and white balancing methods are used as image processing techniques and RGB values and pixels' important information are obtained exactly. Third, during feature extraction stage, with using colormap transformations and feature calculation, comparisons are done in RGB plane between color change values and the 8-color calibration card which is specially designed. Finally, in the bilirubin level estimation stage, kNN and SVR machine learning regressions are used on the dataset which are obtained from feature extraction. At the end of the process, when the control group is based on for comparisons, jaundice is succesfully detected for 40 jaundiced infants and the success rate is 85 %. Obtained bilirubin estimation results are consisted with bilirubin results which are obtained from the standard blood test and the compliance rate is 85 %.

    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.

    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. PMID:26734126

  9. Neurophysiological aspects of neonatal seizures.

    PubMed

    Watanabe, Kazuyoshi

    2014-05-01

    Recently, amplitude-integrated EEG (aEEG) has been increasingly used and proved useful in neonatal intensive care units (NICU) for the management of neonatal seizures. It does not replace, but is supplementary to standard EEG. This article reviews some of findings obtained with standard EEGs, and tries to interpret them with recent findings in the field of basic science. Seizures mainly occur in active-REM sleep in neonates. This is in sharp contrast to those in older children and adults, in whom epileptic seizures occur mainly in NREM sleep. This may be explained by neurotransmitter effects on sleep mechanisms of the neonatal brain that are different from those of older individuals. When all clinical seizures have no electrical correlates, they are non-epileptic, but when the correlation between clinical seizures and frequent electrical discharges are inconsistent, they should rather be considered epileptic, reflecting progression of status epilepticus causing electro-clinical dissociation. Electro-clinical dissociation is not a characteristic of neonatal seizures per se, but a feature of prolonged status epilepticus in adults as well as children. It occurs when prolonged status epilepticus itself causes a progressively severe encephalopathy, or when status occurs in the presence of a severe underlying encephalopathy. In neonates without pre-existing brain damage, frequent seizures per se may cause mild depression characterized by the loss of high voltage slow patterns, an important constituent of slow wave sleep reflecting cortico-cortical connectivity. Mild depression only in the acute stage is not associated with neurological sequelae, but previously damaged brain may be more vulnerable than normal brain.

  10. Neonatal anesthesia with limited resources.

    Bösenberg, Adrian T

    2014-01-01

    Neonates are the most vulnerable age group in terms of anesthetic risk and perioperative mortality, especially in the developing world. Prematurity, malnutrition, delays in presentation, and sepsis contribute to this risk. Lack of healthcare workers, poorly maintained equipment, limited drug supplies, absence of postoperative intensive care, unreliable water supplies, or electricity are further contributory factors. Trained anesthesiologists with the skills required for pediatric and neonatal anesthesia as well as basic monitoring equipment such as pulse oximetry will go a long way to improve the unacceptably high anesthetic mortality.

  11. Photodegradation of riboflavin in neonates

    SciTech Connect

    Sisson, T.R.

    1987-04-01

    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.

    Neonatal thrombocytopenia is widespread in preterm and term neonates admitted to neonatal intensive care units, with up to one-third of infants demonstrating platelet counts <150 × 10(9)/L. Thrombocytopenia may arise from maternal, placental or fetal/neonatal origins featuring decreased platelet production, increased consumption, or both mechanisms. Over the past years, innovations in managing neonatal thrombocytopenia were achieved from prospectively obtained clinical data on thrombocytopenia and bleeding events, animal studies on platelet life span and production rate and clinical use of fully automated measurement of reticulated platelets (immature platelet fraction). This review summarizes the pathophysiology of neonatal thrombocytopenia, current management including platelet transfusion thresholds and recent developments in megakaryopoietic agents. Furthermore, we propose a novel index score for bleeding risk in thrombocytopenic neonates to facilitate clinician's decision-making when to transfuse platelets.

    2017-01-01

    Objectives Neonatal hypoglycaemia is a potential cause of neonatal morbidity, and on rare but tragic occasions causes long-term neurodevelopmental harm with consequent emotional and practical costs for the family. The organisational cost to the NHS includes the cost of successful litigation claims. The purpose of the review was to identify themes that could alert clinicians to common pitfalls and thus improve patient safety. Design The NHS Litigation Authority (NHS LA) Claims Management System was reviewed to identify and review 30 claims for injury secondary to neonatal hypoglycaemia, which were notified to the NHS LA between 2002 and 2011. Setting NHS LA. Patients Anonymised documentation relating to 30 neonates for whom claims were made relating to neonatal hypoglycaemia. Dates of birth were between 1995 and 2010. Interventions Review of documentation held on the NHS LA database. Main outcome measures Identifiable risk factors for hypoglycaemia, presenting clinical signs, possible deficits in care, financial costs of litigation. Results All claims related to babies of at least 36 weeks’ gestation. The most common risk factor for hypoglycaemia was low birth weight or borderline low birth weight, and the most common reported presenting sign was abnormal feeding behaviour. A number of likely deficits in care were reported, all of which were avoidable. In this 10-year reporting period, there were 25 claims for which damages were paid, with a total financial cost of claims to the NHS of £162 166 677. Conclusions Acknowledging that these are likely to be the most rare but most seriously affected cases, the clinical themes arising from these cases should be used for further development of training and guidance to reduce harm and redivert NHS funds from litigation to direct care.

    In the child cardiocentre in Prague 5-Motol in 1977-1993 a total of 420 neonates with critical inborn heart disease were operated. Obstructive defects of the left heart were found in 178 children, obstructive defects of the right heart in 87, defects with a left-right shunt with pulmonary hypertension in 75, conotruncal malformations in 73 and various operations were made in 7 children. Complete repair of the defect was achieved in 281 neonates, incl. 104 where extracorporeal circulation was used. Palliative operations were made in 139 children. Early mortality during the entire period was 26%, whereby a decrease from 40% to 16% was recorded during the last three years. At present it is possible to repair permanently critical inborn heart disease in the majority of neonates. This is made possible in particular by early non-invasive diagnosis, treatment with prostaglandins E in duct-dependent critical heart disease, optimal time for and selection of most suitable surgery, microsurgical technique, miniaturization of extracorporeal circulation and the method of deep hypothermia.

    PubMed Central

    Ghosh, Sangita

    2015-01-01

    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.

    PubMed

    Obeid, Rawad; Tsuchida, Tammy N

    2016-10-01

    Conventional EEG and amplitude-integrated electroencephalography are used in neonates to assess prognosis and significant changes in brain activity. Neuroactive medications and hypothermia can influence brain activity and therefore alter EEG interpretation. There are limited studies on the effect of these therapies on neonatal EEG background activity. Medication effects on the EEG or amplitude-integrated electroencephalography include increased interburst interval duration, voltage suppression, and sleep disruption. The effect is transient in term newborns but can be persistent in premature newborns. Although therapeutic hypothermia does not produce significant changes in EEG activity, it does change the time point at which EEG can accurately predict neurodevelopmental outcome. It is important to account for these effects on the EEG to avoid inaccurate interpretation that may affect prognostication.

    2014-01-01

    SUMMARY Early-onset sepsis remains a common and serious problem for neonates, especially preterm infants. Group B streptococcus (GBS) is the most common etiologic agent, while Escherichia coli is the most common cause of mortality. Current efforts toward maternal intrapartum antimicrobial prophylaxis have significantly reduced the rates of GBS disease but have been associated with increased rates of Gram-negative infections, especially among very-low-birth-weight infants. The diagnosis of neonatal sepsis is based on a combination of clinical presentation; the use of nonspecific markers, including C-reactive protein and procalcitonin (where available); blood cultures; and the use of molecular methods, including PCR. Cytokines, including interleukin 6 (IL-6), interleukin 8 (IL-8), gamma interferon (IFN-γ), and tumor necrosis factor alpha (TNF-α), and cell surface antigens, including soluble intercellular adhesion molecule (sICAM) and CD64, are also being increasingly examined for use as nonspecific screening measures for neonatal sepsis. Viruses, in particular enteroviruses, parechoviruses, and herpes simplex virus (HSV), should be considered in the differential diagnosis. Empirical treatment should be based on local patterns of antimicrobial resistance but typically consists of the use of ampicillin and gentamicin, or ampicillin and cefotaxime if meningitis is suspected, until the etiologic agent has been identified. Current research is focused primarily on development of vaccines against GBS. PMID:24396135

    Burkholderia cepacia is a rare cause of sepsis in newborns and its transmission involves human contact with heavily contaminated medical devices and disinfectants. The authors aimed to determine epidemiology, clinical features, antibiotic sensitivity pattern, complications and outcome of blood culture proven B. cepacia infections in 12 neonates. All neonates were outborn, 5 preterm and 7 term. B. cepacia was isolated from blood in all and concurrently from CSF in three neonates. Lethargy and respiratory distress (41.7 %) were major presenting features. Five newborns (41.7 %) required mechanical ventilation for 3-7 d. Highest bacterial susceptibility was observed for meropenem (100 %), followed by cefoperazone-sulbactam, piperacillin-tazobactam, sulfamethoxazole-trimethoprim (all 83 %), ceftazidime (75 %) and ciprofloxacin (42 %). Piperacillin-tazobactam, ciprofloxacin and cotrimoxazole either singly or in combination led to complete recovery of 11 (91.7 %) newborns; one developed hydrocephalus. Eight of nine infants who completed 6 mo follow up were normal. Prompt recognition and appropriate antibiotic therapy for B. cepacia infection results in complete recovery in majority.

  2. Management of Shock in Neonates.

    PubMed

    Bhat, B Vishnu; Plakkal, Nishad

    2015-10-01

    Shock is characterized by inadequate oxygen delivery to the tissues, and is more frequent in very low birth weight infants, especially in the first few days of life. Shock is an independent predictor of mortality, and the survivors are at a higher risk of neurologic impairment. Understanding the pathophysiology helps to recognize and classify shock in the early compensated phase and initiate appropriate treatment. Hypovolemia is rarely the primary cause of shock in neonates. Myocardial dysfunction is especially common in extremely preterm infants, and in term infants with perinatal asphyxia. Blood pressure measurements are easy, but correlate poorly with cerebral and systemic blood flows. Point-of-care cardiac ultrasound can help in individualized assessment of problems, selecting appropriate therapy and monitoring response, but may not always be available, and long-term benefits need to be demonstrated. The use of near-infrared spectroscopy to guide treatment of neonatal shock is currently experimental. In the absence of hypovolemia, excessive administration of fluid boluses is inappropriate therapy. Dobutamine and dopamine are the most common initial inotropes used in neonatal shock. Dobutamine has been shown to improve systemic blood flow, especially in very low birth weight infants, but dopamine is better at improving blood pressure in hypotensive infants. Newer inodilators including milrinone and levosimendan may be useful in selected settings. Data on long-term survival and neurologic outcomes following different management strategies are scarce and future research efforts should focus on this.

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

    PubMed

    Neonates are predisposed to infections during the perinatal period due to multiple exposures and a relatively compromised immune system. The burden of disease attributed to neonatal infections varies by geographic region and maternal and neonatal risk factors. Worldwide, it is estimated that more than 1.4 million neonatal deaths annually are the consequence of invasive infections. Risk factors for early-onset neonatal sepsis (EOS) include prematurity, immunologic immaturity, maternal Group B streptococcal colonization, prolonged rupture of membranes, and maternal intra-amniotic infection. Intrapartum antimicrobial prophylaxis administered to GBS-colonized women has reduced the burden of disease associated with early onset GBS invasive infections. Active surveillance has identified Gram-negative pathogens as an emerging etiology of early-onset invasive infections. Late-onset neonatal sepsis (LOS) attributable to Gram-positive organisms, including coagulase negative Staphylococci and Staphylococcus aureus, is associated with increased morbidity and mortality among premature infants. Invasive candidiasis is an emerging cause of late-onset sepsis, especially among infants who receive broad spectrum antimicrobial agents. Prophylactic fluconazole administration to very low birthweight (VLBW) neonates during the first 6 weeks of life reduces invasive candidiasis in neonatal intensive care units with high rates of fungal infection. Prevention of healthcare associated infections through antimicrobial stewardship, limited steroid use, early enteral feeding, limited use of invasive devices and standardization of catheter care practices, and meticulous hand hygiene are important and cost-effective strategies for reducing the burden of late-onset neonatal sepsis.

    Leukaemia in neonates (infants <1 month) is rare, whereby neonatal acute myeloid leukaemia (AML) is more frequent than neonatal acute lymphoblastic leukaemia (ALL). High mortality rates are observed, though AML has a better prognosis than ALL. Neonatal leukaemia is typically presented with hepatosplenomegaly, leukaemia cutis and/or hyperleucocytosis. Congenital infections should be ruled out before diagnosis. Rearrangement of the MLL gene is the most frequently occurring genetic aberration. Treatment includes intensive multi-agent chemotherapy, usually with age-related dose adjustments next to supportive care. Treatment intensification for ALL could be indicated in the future as the dismal prognosis is subject to high relapse rates in ALL.

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

    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

    OBJECTIVES: To describe the spectrum of cognitive outcomes of children with and without cerebral palsy (CP) after neonatal encephalopathy, evaluate the prognostic value of early developmental testing and report on school services and additional therapies. METHODS: The participants of this study are the school-aged survivors of the National Institute of Child Health and Human Development Neonatal Research Network randomized controlled trial of whole-body hypothermia. Children underwent neurologic examinations and neurodevelopmental and cognitive testing with the Bayley Scales of Infant Development–II at 18 to 22 months and the Wechsler intelligence scales and the Neuropsychological Assessment–Developmental Neuropsychological Assessment at 6 to 7 years. Parents were interviewed about functional status and receipt of school and support services. We explored predictors of cognitive outcome by using multiple regression models. RESULTS: Subnormal IQ scores were identified in more than a quarter of the children: 96% of survivors with CP had an IQ <70, 9% of children without CP had an IQ <70, and 31% had an IQ of 70 to 84. Children with a mental developmental index <70 at 18 months had, on average, an adjusted IQ at 6 to 7 years that was 42 points lower than that of those with a mental developmental index >84 (95% confidence interval, −49.3 to −35.0; P < .001). Twenty percent of children with normal IQ and 28% of those with IQ scores of 70 to 84 received special educational support services or were held back ≥1 grade level. CONCLUSIONS: Cognitive impairment remains an important concern for all children with neonatal encephalopathy. PMID:25713280

  10. Foetal and neonatal alloimmune thrombocytopaenia.

    PubMed

    Kaplan, Cecile

    2006-10-10

    Foetal/neonatal alloimmune thrombocytopaenia (NAIT) results from maternal alloimmunisation against foetal platelet antigens inherited from the father and different from those present in the mother, and usually presents as a severe isolated thrombocytopaenia in otherwise healthy newborns. The incidence has been estimated at 1/800 to 1/1000 live births. NAIT has been considered to be the platelet counterpart of Rh Haemolytic Disease of the Newborn (RHD). Unlike RHD, NAIT can occur during a first pregnancy. The spectrum of the disease may range from sub-clinical moderate thrombocytopaenia to life-threatening bleeding in the neonatal period. Mildly affected infants may be asymptomatic. In those with severe thrombocytopaenia, the most common presentations are petechiae, purpura or cephalohaematoma at birth, associated with major risk of intracranial haemorrhage (up to 20% of reported cases), which leads to death or neurological sequelae. Alloimmune thrombocytopaenia is more often unexpected and is usually diagnosed after birth. Once suspected, the diagnosis is confirmed by demonstration of maternal antiplatelet alloantibodies directed against a paternal antigen inherited by the foetus/neonate. Post-natal management involves transfusion of platelets devoid of this antigen, and should not be delayed by biological confirmation of the diagnosis (once the diagnosis is suspected), especially in case of severe thrombocytopaenia. Prompt diagnosis and treatment are essential to reduce the chances of death and disability due to haemorrhage. Due to the high rate of recurrence and increased severity of the foetal thrombocytopaenia in successive pregnancies, antenatal therapy should be offered. However, management of high-risk pregnancies is still a matter of discussion.

    2014-04-01

    Carbapenems are an effective tool to treat complicated bacterial infections. This review aims to summarize the available information on carbapenems in neonates to guide clinicians on drug choice and indications in neonates. Moreover, identification of knowledge gaps may stimulate researchers to design studies to further improve pharmacotherapy in neonates. To do so, a bibliographic search [infant/newborn and meropenem, imipenem, panipenem, ertapenem, doripenem or imipenem] was performed (PubMed, EMBASE) and public clinical trial registries (clinicaltrials.gov, EU registry) were searched to summarize the available information. Carbapenem clearance in neonates is low. Variability relates to maturation (weight, age) and renal function (creatinine clearance), while observations in neonates with renal failure are absent. Pharmacodynamics are almost exclusively limited to meropenem, and the available information will further increase (NeoMero-1-2, necrotizing enterocolitis, meningitis). Finally, there are also some ongoing doripenem pharmacokinetics (PK) studies in neonates. It was concluded that observations on carbapenems in neonates are limited, but studies (NeoMero, doripenem) are ongoing. Until this information becomes available, off label prescription of meropenem seems to be the most reasonable choice when a carbapenem is appropriate. Knowledge gaps relate to PK in neonates with renal failure and to the potential benefit of prolonged compared to short duration of infusion.

It produces neurons and glial cells, and is present in the foetal brain between 8 and 36 weeks of gestation. At 25 weeks, it reaches its maximum volume and subsequently withers. The GM is vulnerable to haemorrhage in preterm infants. This selective vulnerability is explained by limited astrocyte end-feet coverage of microvessels, reduced expression of fibronectin and immature tight junctions. Focal lesions in the neonatal period include haemorrhage, germinolysis and stroke. Such lesions in transient layers interrupt normal brain maturation and induce neurodevelopmental sequelae.

    Bacteriological and clinical data on 68 children with neonatal group B streptococcal meningitis were analysed as part of a wider study of bacterial meningitis undertaken between 1976 and 1982. Twenty five per cent of patients died and there was no difference in the mortality rate between early and late onset disease. Sixteen per cent of the infants weighed less than 2500 g at birth but in 50% no predisposing aetiological factor was found. Streptococcus agalactiae type III was isolated in 57% of the patients.

    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.

    The Neonatal Nurse Practitioner Workforce Survey, led by Paula Timoney, DNP, ARNP, NNP-BC, and Debra Sansoucie, EdD, RN, NNP-BC, with the National Association of Neonatal Nurse Practitioners (NANNP), provides data collected from more than 600 neonatal nurse practitioners to examine workforce characteristics and needs. NANNP commissioned the survey because no comprehensive data existed for the neonatal nurse practitioner workforce. The executive summary given in this article highlights some of the survey's key findings in the areas of demographics, practice environment, scope of responsibilities, and job satisfaction. Readers are encouraged to review the complete text of the Neonatal Nurse Practitioner Workforce Survey for more in-depth data and recommendations regarding NNP education, scope of practice, and scope of responsibility in the ever-changing health care environment.

    2014-06-01

    Intravenous drug administration presents a series of challenges that relate to the pathophysiology of the neonate and intravenous infusion systems in neonates. These challenges arise from slow intravenous flow rates, small drug volume, dead space volume and limitations on the flush volume in neonates. While there is a reasonable understanding of newborn pharmacokinetics, an appreciation of the substantial delay and variability in the rate of drug delivery from the intravenous line is often lacking. This can lead to difficulties in accurately determining the pharmacokinetic and pharmacodynamic relationship of drugs in the smallest patients. The physical variables that affect the passage of drugs through neonatal lines need to be further explored in order to improve our understanding of their impact on the delivery of drugs by this route in neonates. Through careful investigation, the underlying causes of delayed drug delivery may be identified and administration protocols can then be modified to ensure predictable, appropriate drug input kinetics.

    Neonatal electroencephalography (EEG) recordings have routinely been performed for more than half a century. ''Old'' technical difficulties are no longer of concern with the advent of modern digital technology. Still, many ''old'' issues are at debate: characterization of neonatal EEG features, identification of EEG waveforms with potential clinical correlates, the role of neonatal EEG in prediction of neurodevelopmental outcome, and use of new devices. In the past decades, neonatal EEG and emerging issues' literature has greatly expanded. In this review, the authors have summarized some of these issues to increase the availability of the information for both clinical and research purposes. They propose an up-to-date concentrated practical approach to this rapidly expanding ''subfield'' of neonatal neurology.

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

    Genital herpes infections are extremely common worldwide and ~22% of pregnant women are infected with herpes simplex virus. Eighty percent of those affected with genital herpes are unaware of being infected. The most devastating consequence of maternal genital herpes is neonatal herpes disease. Fortunately, neonatal herpes simplex infections are uncommon but due to the morbidity and mortality associated with the infection are often considered in the differential diagnosis of ill neonates. The use of polymerase chain reaction assay for diagnosis of central nervous system infections and the development of safe and effective antiviral therapy have revolutionized the diagnosis and management of these infants. Most recently, the initiation of long-term antiviral suppressive therapy in these infants has led to significant improvement in morbidity. This review will summarize the epidemiology of maternal and neonatal herpes infections and discuss clinical presentation, diagnosis, management, and follow-up of infants with neonatal herpes disease.

    The aim of the study was to determine the presence of acupuncture ear points in neonates with Neonatal Abstinence Syndrome (NAS). NAS occurs in the first days of life in neonates whose mothers have a history of drug abuse, and may also occur in neonates whose mothers are currently following substitution therapy. The patients are neonates with NAS admitted over one year to the Division of Neonatology at the University Hospital Graz. The examination took place on the third day after delivery (mean value 70.3 hours) and was performed by a neuronal pen (PS 3 © Silberbauer, Vienna, Austria). An integrated sound and optical signal detected the active ear points that were then placed on an ear map. We investigated six neonates (four male, two female). All investigated neonates showed the presence of active ear acupuncture points. The psychovegetative rim was the most common organic area of the children, following by a few organic points. This corresponds with the results found in healthy neonates. In all neonates with NAS, we found the presence of psychic ear points. The identified psychic ear points are the frustration-point, R-point and the psychotropic area nasal from the incisura intertragica. In all neonates with NAS, active organic and psychic ear points were detectable in both ears. In the future, it could be possible to use active ear points for diagnostic and therapeutic purposes.

  5. Antibiotic use in neonatal sepsis.

    PubMed

    Yurdakök, M

    1998-01-01

    Neonatal sepsis is a life-threatening emergency and any delay in treatment may cause death. Initial signs of neonatal sepsis are slight and nonspecific. Therefore, in suspected sepsis, two or three days empirical antibiotic therapy should begin immediately after cultures have been obtained without awaiting the results. Antibiotics should be reevaluated when the results of the cultures and susceptibility tests are available. If the cultures are negative and the clinical findings are well, antibiotics should be stopped. Because of the nonspecific nature of neonatal sepsis, especially in small preterm infants, physicians continue antibiotics once started. If a baby has pneumonia or what appears to be sepsis, antibiotics should not be stopped, although cultures are negative. The duration of therapy depends on the initial response to the appropriate antibiotics but should be 10 to 14 days in most infants with sepsis and minimal or absent focal infection. In infants who developed sepsis during the first week of life, empirical therapy must cover group B streptococci, Enterobacteriaceae (especially E. coli) and Listeria monocytogenes. Penicillin or ampicillin plus an aminoglycoside is usually effective against all these organisms. Initial empirical antibiotic therapy for infants who developed sepsis beyond the first days of life must cover the organisms associated with early-onset sepsis as well as hospital-acquired pathogens such as staphylococci, enterococci and Pseudomonas aeruginosa. Penicillin or ampicillin and an aminoglycoside combination may also be used in the initial therapy of late-onset sepsis as in cases with early-onset sepsis. In nosocomial infections, netilmicin or amikacin should be preferred. In cases showing increased risk of staphylococcal infection (e.g. presence of vascular catheter) or Pseudomonas infection (e.g. presence of typical skin lesions), antistaphylococcal or anti-Pseudomonas agents may be preferred in the initial empirical therapy.

    PubMed

    2007-01-01

    Fungal infections are responsible for considerable morbidity and mortality in the neonatal period, particularly among premature neonates. Four classes of antifungal agents are commonly used in the treatment of fungal infections in pediatric patients: polyene macrolides, fluorinated pyrimidines, triazoles, and echinocandins. Due to the paucity of pediatric data, many recommendations for the use of antifungal agents in this population are derived from the experience in adults. The purpose of this article was to review the published data on fungal infections and antifungal agents, with a focus on neonatal patients, and to provide an overview of the differences in antifungal pharmacology in neonates compared with adults. Pharmacokinetic data suggest dosing differences in children versus adult patients with some antifungals, but not all agents have been fully evaluated. The available pharmacokinetic data on the amphotericin B deoxycholate formulation in neonates exhibit considerable variability; nevertheless, the dosage regimen suggested in the neonatal population is similar to that used in adults. More pharmacokinetic information is available on the liposomal and lipid complex preparations of amphotericin B and fluconazole, and it supports their use in neonates; however, the optimal dosage and duration of therapy is difficult to establish. All amphotericin-B formulations, frequently used in combination with flucytosine, are useful for treating disseminated fungal infections and Candida meningitis in neonates. Fluconazole, with potent in vitro activity against Cryptococcus neoformans and almost all Candida spp., has been used in neonates with invasive candidiasis at dosages of 6 mg/kg/day, and for antifungal prophylaxis in high-risk neonates. There are limited data on itraconazole, voriconazole, and posaconazole use in neonates. Caspofungin, which is active against Candida spp. and Aspergillus spp., requires higher doses in children relative to adults, and dosing is

    There are significant differences between the coagulation system in neonates compared with children and adults. Abnormalities of standard coagulation tests are common within the neonatal population. The laboratory tests of activated partial thromboplastin time (aPTT) and prothrombin time (PT) were developed to investigate coagulation factor deficiencies in patients with a known bleeding history, and their significance and applied clinical value in predicting bleeding (or thrombotic) risk in critically ill patients is weak. Routine screening of coagulation on admission to the neonatal intensive care unit leads to increased use of plasma for transfusion. Fresh frozen plasma (FFP) is a human donor plasma frozen within a short specified time period after collection (often 8 h) and then stored at -30°C. FFP has little effect on correcting abnormal coagulation tests when mild and moderate abnormalities of PT are documented in neonates. There is little evidence of effectiveness of FFP in neonates. A large trial by the Northern Neonatal Nursing Initiative assessed the use of prophylactic FFP in preterm infants and reported no improvement in clinical outcomes in terms of mortality or severe disability. An appropriate FFP transfusion strategy in neonates should be one that emphasises the therapeutic use in the face of bleeding rather than prophylactic use in association with abnormalities of standard coagulation tests that have very limited predictive value for bleeding.

    Currently, in the Republic of Korea, despite the very-low-birth rate, the birth rate and number of preterm infants are markedly increasing. Neonatal deaths and major complications mostly occur in premature infants, especially very-low-birth-weight infants (VLBWIs). VLBWIs weigh less than 1,500 g at birth and require intensive treatment in a neonatal intensive care unit (NICU). The operation of the Korean Neonatal Network (KNN) officially started on April 15, 2013, by the Korean Society of Neonatology with support from the Korea Centers for Disease Control and Prevention. The KNN is a national multicenter neonatal network based on a prospective web-based registry for VLBWIs. About 2,000 VLBWIs from 60 participating hospital NICUs are registered annually in the KNN. The KNN has built unique systems such as a web-based real-time data display on the web site and a site-visit monitoring system for data quality surveillance. The KNN should be maintained and developed further in order to generate appropriate, population-based, data-driven, health-care policies; facilitate active multicenter neonatal research, including quality improvement of neonatal care; and ultimately lead to improvement in the prognosis of high-risk newborns and subsequent reduction in health-care costs through the development of evidence-based neonatal medicine in Korea.

    Each year in the US, some four hundred thousand newborns need help breathing when they are born. 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. We hope this report provides a succinct review of recent advances in neonatal resuscitation. PMID:28096704

    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.

    The Bronson Methodist Hospital Neonatal Transport System (Kalamazoo, MI) has identified effective communication as a necessity when providing optimal patient care. Our experience shows that good communication comes only from good relationships between our neonatal intensive care unit (NICU) staff and each referring hospital's staff. This article describes the two educational methods used to aid these relationships: the development of site visits and the distribution of informative publications. By using these methods, our relationships with our 17 referring hospital staffs have improved, which has had a direct bearing on more effective communication during neonatal transport.

    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

    Acute renal failure (ARF) in a neonate is a serious condition that impacts 8% to 24% of hospitalized neonates. There is a need for prompt evaluation and treatment to avoid additional complications. In this review, a neonate was found to have renal failure associated with renal vein thrombosis. There are varying etiologies of ARF. Causes of ARF are typically divided into three subsets: pre-renal, renal or intrinsic, and post-renal. Treatment of ARF varies based on the cause. Renal vein thrombosis is an interesting cause of renal or intrinsic ARF and can be serious, often leading to a need for dialysis.

A review of spinal embryology followed by a description of common spinal diseases in neonates assessed with ultrasound is presented. Indications for spinal ultrasound in neonates, commonly identified conditions, and the importance of magnetic resonance imaging in selected cases are emphasized. Additionally, the use of ultrasound in selected neurosurgical spinal diseases in pediatric patients is presented with magnetic resonance imaging and intraoperative correlation. Technique, limitations, and pitfalls are discussed.

    The increase in the number of multiple pregnancies and the high incidence of prematurity in this type of pregnancy justifies a pediatric evaluation. A retrospective study (1985-1989) compared the perinatal and neonatal characteristics of children resulting from 14 multifetal (at least 3 fetuses) pregnancies, with a gestational age of less than 34 weeks, with 27 children resulting from monofetal pregnancies of the same duration. Neonatal morbidity and mortality appeared to be similar in both groups. Thus at this very early time of onset of labour (mean gestational age of 30 weeks), fetal multiplicity expressed itself neither by any particular neonatal pathology nor by malnutrition.

    2010-01-01

    There are a limited number of artistic objects from ancient times with particular importance in neonatal medicine. The best examples are figurines from ancient Egypt of Isis nursing Horus, showing the importance of breastfeeding. The earliest images of the human fetus were made by the Olmecs in Mexico around 1200- 400 BCE. One of the earliest representations of congenital anomalies is a figurine of diencephalic twins thought to be the goddess of Anatolia, dated to around 6500 BCE. In addition to these figurines, three sets of twins in the ancient world have medical importance, and Renaissance artists often used them as a subject for their paintings: "direct suckling animals" (Romulus and Remus), "heteropaternal superfecundation" (mother: Leda, fathers: Zeus, the king of the Olympian gods, and Leda's husband, Tyndareus), and "twin-to-twin transfusion" in monozygotic twins (Jacob and Esau).

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

    A 5-day-old Thoroughbred foal was submitted to the necropsy service at the University of Kentucky Livestock Disease Diagnostic Center. The foal had a clinical history of seizure activity and severe icterus. A complete blood count and serum chemistry analysis indicated that the foal was anemic (hematocrit, 16%), hyperbilirubinemic (45 mg/dl), and hypoglycemic. 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.

    2003-10-01

    The concept of futile care is controversial and difficult to define. Efforts to prolong life, once considered an outcome of healing, may now be viewed by some as harmful acts of prolonging suffering. This article reviews a number of cases representing this challenging ethical dilemma, such as Baby K and MacDonald v. Milleville. The Baby Doe regulations, the Emergency Medical Treatment and Labor Act (EMTALA), and the Born-Alive Protection Act of 2001, also are discussed to provide an improved understanding of the legal framework that impacts ethical decision making. Nurses at the bedside must be equipped with the ethical knowledge and communication skills necessary to care for patients and families facing the ethical dilemma of futile care. An increased focus on neonatal palliative care is suggested to provide infants, families, and staff with the necessary tools to work through this painful process.

    2009-06-01

    There is a little-recognized cohort of NICU patients whose outcomes are the result of a "benevolent injustice" in their healthcare course. Many of these infants are saved by technology; however, they are left both medically fragile and medically dependent, and many of them are required to live in a medical facility. Many of these babies never get to go home with their parents. This emerging cohort of patients may evolve from the difficult ability to prognosticate outcomes for neonates, overtreatment, and acquiescing to parental demands for continued aggressive care. Neonatology is an unpredictable process and one that is never intended to harm, but carries with it the potential of devastating consequences, thus creating a benevolent injustice.

    Setting: A Médecins Sans Frontières emergency obstetric and neonatal care facility specialising as a referral centre for three districts for women with complications during pregnancy or delivery in rural Burundi. Objective: To describe the characteristics and in-facility mortality rates of neonates born in 2011. Design: Descriptive study involving a retrospective review of routinely collected facility data. Results: Of 2285 women who delivered, the main complications were prolonged labour 331 (14%), arrested labour 238 (10%), previous uterine intervention 203 (9%), breech 171 (8%) and multiple gestations 150 (7%). There were 175 stillbirths and 2110 live neonates, of whom 515 (24%) were of low birth weight, 963 (46%) were delivered through caesarean section and 267 (13%) required active birth resuscitation. Overall, there were 102 (5%) neonatal deaths. A total of 453 (21%) neonates were admitted to dedicated neonatal special services for sick and low birth weight babies. A high proportion of these neonates were delivered by caesarean section and needed active birth resuscitation. Of 67 (15%) neonatal deaths in special services, 85% were due to conditions linked to low birth weight and birth asphyxia. Conclusion: Among neonates born to women with complications during pregnancy or delivery, in-facility deaths due to low birth weight and birth asphyxia were considerable. Sustained attention is needed to reduce these mortality rates. PMID:26393046

    Acoustic data from two sperm whale neonates (Physeter macrocephalus) in rehabilitation are presented and implications for sound production and function are discussed. The clicks of neonate sperm whale are very different from usual clicks of adult specimens in that neonate clicks are of low directionality [SL anomaly (0°-90°) <8 dB], long duration (2-12 ms), and low frequency (centroid frequency between 300 and 1700 Hz) with estimated SLs between 140 and 162 dB//1 μPa (rms). Such neonate clicks are unsuited for biosonar, but can potentially convey homing information between calves and submerged conspecifics in open ocean waters at ranges of some 2 km. Moreover, it is demonstrated that sperm whale clicks are produced at the anterior placed monkey lips, thereby substantiating a key point in the modified Norris and Harvey theory and supporting the unifying theory of sound production in odontocetes.

    2011-08-01

    During the last decade rapid development has occurred in defining nuclear gene mutations causing mitochondrial disease. Some of these newly defined gene mutations cause neonatal or early infantile onset of disease, often associated with severe progressive encephalomyopathy combined with other multi-organ involvement such as cardiomyopathy or hepatopathy and with early death. Findings suggesting myopathy in neonates are hypotonia, muscle weakness and wasting, and arthrogryposis. We aim to describe the clinical findings of patients with mitochondrial disease presenting with muscular manifestations in the neonatal period or in early infancy and in whom the genetic defect has been characterized. The majority of patients with neonatal onset of mitochondrial disease have mutations in nuclear genes causing dysfunction of the mitochondrial respiratory chain, leading to defective oxidative phosphorylation.

    Introduction Neonatal transport involves moving sick neonates in optimal conditions to ensure good outcomes. It is well organized in most developed countries but receives little attention in developing countries where the highest burden of neonatal mortality exists and a large number of newborns require referrals daily for better medical care. This study sought to evaluate the modes of transport, pre- and intra-transport care of neonates referred to the University College Hospital (UCH), Ibadan, Nigeria. Methods The methods of transporting 401 neonates presenting to the children’s emergency room of the hospital were evaluated as well as the care the babies received during transport. Categorical variables were compared using the Chi square test while continuous variables were compared by the student t-test. Results About a third presented in the first 12hours and 85% in the first week of life, all from within 80km radius. There were 67.1% term, 31.4% preterm and 1.5% post-term neonates, all without prior communication. The modes of transport included private vehicles (43.9%), commercial vehicles (40.6%), motorcycles (9.0%), ambulance (4.0%) and on foot (2.5%). Only 3 (0.7%) were transported in incubators and none in KMC position. Only 42.0% had referral letters and 7.0% were accompanied by medical personnel. Materials available during transport included Ambubags (3.7%), oxygen (3.5%) and some drugs (3.5%). Events during transport were apnoea, 4.7%, vomiting 1.0%, reduced activity 16.2% and seizures 13.7%. 19 (4.7%) neonates were dead on arrival. Pre-transport care included resuscitation (18.2%), intravenous fluid/feeding (24.4%) and supplemental oxygen (14.0%). Conclusion Neonatal transport practices in Ibadan, Nigeria are abysmal with associated high mortality. PMID:27800071

    Background The incidence of neonatal opioid withdrawal is increasing in both Canada and the United States. However, the degree to which the treatment of pain with opioids, rather than the misuse of prescription opioids or heroin, contributes to the prevalence of neonatal opioid withdrawal remains unknown. Methods We conducted a retrospective, population-based, cross-sectional study between 1992 and 2011 in Ontario with 2 objectives. First, we determined the annual incidence of neonatal abstinence syndrome. Second, using data from a subset of women eligible for publicly funded prescription drugs, we determined what proportion of women who deliver an infant with neonatal abstinence syndrome were given a prescription for an opioid before and during pregnancy. Results The incidence of neonatal abstinence syndrome in Ontario increased 15-fold during the study period, from 0.28 per 1000 live births in 1992 to 4.29 per 1000 live births in 2011. During the final 5 years of the study, we identified 927 deliveries of infants with neonatal abstinence syndrome to mothers who were public drug plan beneficiaries. Of these mothers, 67% had received an opioid prescription in the 100 days preceding delivery, including 53.3% who received methadone, an increase from 28.6% in the interval spanning 1 to 2 years before delivery (p < 0.001). Prescription for nonmethadone opioids decreased from 38% to 17% (p < 0.001). Interpretation The incidence of neonatal opioid withdrawal in Ontario has increased substantially over the last 20 years. Most of the women in this cohort who delivered an infant with neonatal abstinence syndrome had received a prescription for an opioid both before and during their pregnancy. PMID:25844370

    A 10-day-old, Japanese Black, female calf had shown astasia since just after birth. Focal symmetrical periventricular malacic lesions of the cerebrum and suppurative arthritis of the left hip joint were observed in macroscopic examination. Histologically, the cerebral lesions were confirmed as periventricular leukomalacia (PVL). The location and histological features of the lesions were similar to PVL in humans, caused by neonatal ischemia/hypovolemia. This is the first report of PVL in a neonatal calf. PMID:27010465

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

    Systemic fungal infections pose insidious challenges in neonatal intensive care settings. We present the case of a 9-day-old male term neonate admitted for polymicrobial sepsis and hepatic dysfunction who later developed candidemia superinfection. Despite broad antifungal therapy, the fungemia was complicated by progressive growth of a fungus ball in the right ventricular outflow tract that threatened cardiac function. Surgical excision of the mass was undertaken by right atriotomy and histologic examination confirmed Candida albicans. PMID:28289498

    Objective Prevalence of neonatal stroke has been reported 1/2300-1/4000 live births and accounts for 12-20% of the cases of neonatal seizures. Although stroke has been introduced as the second cause of the neonatal seizures in literatures, it may remain unclear in diagnostic evaluations of seizure in neonates. This study was performed to assess the prevalence of stroke in neonates with seizure. Materials & Methods In this cross-sectional study, all neonates ≥ 28 weeks of gestation with a diagnosis of seizures admitted to the NICU of Boo-Ali Sina Hospital in Sari, north of Iran, were enrolled. Brain CT scan and a Transcranial Doppler ultrasonography were performed for the all cases. In cases that stroke were reported in one or two above modalities, an MRI was also performed and prevalence of stroke was reported. Putative risk factors of stroke were analyzed with univariate and multivariate statistical methods. Results From 174 newborn infants, 75.3% of neonates were male. Prevalence of stroke was 8%, 2.3% and 3.4% in Doppler ultrasonography, CT scan and MRI reports respectively. Umbilical venous catheterization was the risk factor of stroke in the univariate and multivariate analysis (P= 0.001; OR, 10.39; 95% CI, 2.72- 39.77). The most common form of seizure was focal clonic seizures (78.6%) in neonates with stroke. Conclusion Investigation of stroke as an etiology of neonatal seizures is essential because seizure may be the only symptom of neonatal cerebral infarction. Doppler ultrasonography can be a valuable diagnostic tool at first in critically ill neonates or in situations that MRI is not available primarily. Further studies with notice to outcome assessment of these infants recommended. PMID:26664440

    Background This study aimed to evaluate the radiation dose received by premature neonates using diagnostic radiographies. Methods This cross-sectional study was conducted on 116 premature neonates with gestational age from 25 to 37 weeks; with the diagnosis of neonatal respiratory distress syndrome (NRDS) and tachypnea, they were admitted to a neonatal intensive care unit (NICU) at Ahvaz Imam Khomeini Hospital in 2015. For assessing the dose received, the model GR-200 thermoluminescent dosimeter (TLD) was used. For each premature neonate under radiation, three TLDs separately (one for each) were placed on surfaces of Ch1, T1, and G1 (chest, thyroid, and gonad of first newborn, respectively). Moreover, for the adjacent neonate at a distance of 60 - 100 cm, two TLDs were laid in the surfaces of T2 and G2 (thyroid and gonad of second newborn, respectively). The dose received by TLDs for any baby and the adjacent neonate under the entrance surface dose (ESD) was estimated. Results The mean of neonates’ weight under study was 1,950.78 ± 484.9 g. During the hospitalization period, minimum one and maximum three radiographies were done for any premature neonate. The doses received in the premature neonates to Ch1, T1 and G1 were 0.08 ± 0.01, 0.06 ± 0.01, and 0.05 ± 0.01 mSv, respectively and for adjacent infants for T2 and G2 were 0.003 ± 0.001 and 0.002 ± 0.0009 mSv, respectively. Conclusions In the study, radiation dose received by organs at risk of premature neonates was lower than the international criteria and standards, therefore, also due to the lack of radiation damage threshold, to limit collimator, and the use of the proper filtration, kilovoltage and time during radiography of premature neonates are recommended.

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

    The aims of this study were to detect the frequency at which the different types of neonatal jaundice occur in Makkah and to estimate the malondialdehyde (MDA) levels. This study included 239 neonates with neonatal jaundice, 20 anemic neonates and 21 healthy neonates. ABO incompatibility was observed in 31.6% of neonates with indirect hyperbilirubinemia, in 14.3% of those with early onset jaundice, in 9.5% of those with persistent jaundice, in 8.5% of those with physiological jaundice, in 5% of anemic neonates and in 12% of all neonates. glucose-6-phosphate dehydrogenase (G6PD) deficiency was observed in 10.5% of neonates with indirect hyperbilirubinemia, in 3.9% of those with physiological jaundice, in 11.1% of those with direct hyperbilirubinemia, in 12% of those with persistent jaundice, in 10% of anemic neonates and in 6.6% of all neonates. Rh incompatibility and polycythemia were found in 2.6% of neonates with indirect hyperbilirubinemia and in 0.4% of all neonates. In comparison to control group, MDA was significantly higher in all groups except for the anemic group. In conclusion, ABO incompatibility and G6PD deficiency frequently result in neonatal jaundice in Makkah, whereas Rh incompatibility and polycythemia are rare. The MDA level may serve as an indicator of oxidative stress.

    Neonatal lupus is a rare and acquired autoimmune disease. Central nervous system abnormalities are potential manifestations in neonatal lupus. Through a systematic literature review, we analyzed the clinical features of previously reported neonatal lupus cases where central nervous system abnormalities had been identified. Most reported neonatal lupus patients with central nervous system involvement were neuroimaging-determined and asymptomatic. Only seven neonatal lupus cases were identified as having a symptomatic central nervous system abnormality which caused physical disability or required neurosurgery. A high percentage of these neurosymptomatic neonatal lupus patients had experienced a transient cutaneous skin rash and had no maternal history of autoimmune disease before pregnancy.

    Despite recent advances in neonatal medicine, neonatal disorders, such as bronchopulmonary dysplasia and intraventricular hemorrhage in preterm neonates and hypoxic ischemic encephalopathy in term neonates, remain major causes of mortality and morbidities. Promising preclinical research results suggest that stem cell therapies represent the next breakthrough in the treatment of currently intractable and devastating neonatal disorders with complex multifactorial etiologies. This review focuses primarily on the potential role of stem cell therapy in the above mentioned neonatal disorders, highlighting the results of human clinical trials and the challenges that remain to be addressed for their safe and successful translation into clinical care of newborn infants.

    Neonatal ventilation is an integral component of care delivered in the neonatal unit. The aim of any ventilation strategy is to support the neonate's respiratory system during compromise while limiting any long-term damage to the lungs. Understanding the principles behind neonatal ventilation is essential so that health professionals caring for sick neonates and families have the necessary knowledge to understand best practice. Given the range of existing ventilation modes and parameters available, these require explanation and clarification in the context of current evidence. Many factors can influence clinical decision making on both an individual level and within the wider perspective of neonatal care.

    Objective: To determine the frequency of hypocalcemia in term neonates with jaundice receiving phototherapy. Methods: This was a cross sectional study conducted at Neonatal intensive care unit, National Institute of Child Health, Karachi from 1st January 2014 to 30th December 2014. A total of 123 term neonates with jaundice of either gender managed by phototherapy were enrolled in the study. Gestational age was assessed through modified Ballard scoring. Duration of phototherapy was recorded. A sample of 3 ml of blood was sent to the laboratory for serum calcium level before initiating phototherapy and after 24 hours of continued phototherapy. All the data were recorded in the preformed proforma. Data was analyzed using SPSS version 19. P value <0.05 was taken as significant. Results: The mean age of the neonates was 8.35±6.74 days. Mean gestational age at the time of birth was 39.08±1.37 weeks. Mean duration of jaundice was 2.4±1.20 days. Mean duration of phototherapy was 1.74±0.98 days. Serum calcium level before and after 24 hours of initiating phototherapy was 8.73±0.68 mg/dl and 7.47±0.82mg/dl respectively Frequency of hypocalcemia in term jaundiced neonates receiving phototherapy were observed in 22.76% (28/123). Conclusions: The frequency of hypocalcemia is significant in the jaundiced neonates treated with phototherapy. One needs to be vigilant in dealing neonates in this context while serial monitoring for hypocalcemia and its complications should be considered in institutional policy and research priority.

    Neonatal sepsis is one of the major health problems throughout the world. Every year an estimated 30 million newborns acquire infection and 1-2 million of these die. The present review provides updates regarding neonatal sepsis to help paediatricians to protect the newborn from this deadly problem. The onset of sepsis within first 48 hours of life (early onset sepsis) is frequently associated with pre and perinatal predisposing factors while onset after 48-72 hours of life (late onset sepsis) frequently reflects infection acquired nosocomially. Some literatures say that early onset disease presents in the first 5-7 days of life. Klebsiella pneumoniae is the leading pathogen causing neonatal sepsis in Bangladesh and neighbouring countries. Among many risk factors the single most important neonatal risk factor is low birth weight. Other main risk factors are invassive procedures in the postnatal period and inadequate hand washing before and after handling babies. Sepsis score is a useful method for early and rapid diagnosis of neonatal sepsis which was developed by Tollner U in 1982. Antibiotics should be given to most of the neonates suspected of infection. Ampicillin and gentamicin are the first drug of choice. In Bangladesh context sepsis score may be used as a good parameter for the early and rapid diagnosis of sepsis and that will guide the treatment plan. Clean and safe delivery, early and exclusive breastfeeding, strict postnatal cleanliness following adequate handwashing and aseptic technique during invasive procedure might reduce the incidence of neonatal sepsis. Prompt use of antibiotic according to standard policy is warranted to save the newborn lives from septicaemia.

    The acquisition of high-quality magnetic resonance (MR) images of neonatal brains is largely hampered by their characteristically small head size and insufficient tissue contrast. As a result, subsequent image processing and analysis, especially brain tissue segmentation, are often affected. To overcome this problem, a dedicated phased array neonatal head coil is utilized to improve MR image quality by augmenting signal-to-noise ratio and spatial resolution without lengthening data acquisition time. In addition, a specialized hybrid atlas-based tissue segmentation algorithm is developed for the delineation of fine structures in the acquired neonatal brain MR images. The proposed tissue segmentation method first enhances the sheet-like cortical gray matter (GM) structures in the to-be-segmented neonatal image with a Hessian filter for generation of a cortical GM confidence map. A neonatal population atlas is then generated by averaging the presegmented images of a population, weighted by their cortical GM similarity with respect to the to-be-segmented image. Finally, the neonatal population atlas is combined with the GM confidence map, and the resulting enhanced tissue probability maps for each tissue form a hybrid atlas that is used for atlas-based segmentation. Various experiments are conducted to compare the segmentations of the proposed method with manual segmentation (on both images acquired with a dedicated phased array coil and a conventional volume coil), as well as with the segmentations of two population-atlas-based methods. Results show the proposed method is capable of segmenting the neonatal brain with the best accuracy, and also preserving the most structural details in the cortical regions. PMID:20690143

    Neonatal mortality is a major health problem in low and middle income countries and the rate of improvement of newborn survival is slow. This article is a review of the PhD thesis by Mats Målqvist, titled ‘Who can save the unseen – Studies on neonatal mortality in Quang Ninh province, Vietnam,’ from Uppsala University. The thesis aims to investigate structural barriers to newborn health improvements and determinants of neonatal death. The findings reveal a severe under-reporting of neonatal deaths in the official health statistics in Quang Ninh province in northern Vietnam. The neonatal mortality rate (NMR) found was four times higher than what was reported to the Ministry of Health. This underestimation of the problem inhibits adequate interventions and efforts to improve the survival of newborns and highlights the invisibility of this vulnerable group. The findings of the thesis also point at an inequity in survival chances based on ethnicity of the mother. Newborns of ethnic minority mothers were at a twofold risk of dying within the first 4 weeks of life compared to their peers belonging to the hegemonic group of Kinh (OR 2.08, 95% CI: 1.39–3.10). This increased risk was independent of maternal education and household economic status. Neonatal mortality was also associated with home deliveries, non-attendance to antenatal care and distance to the health care facilities. However, ethnic minority mothers still had an increased risk of experiencing a neonatal death even if they attended antenatal care, delivered at, or lived close to a health facility. This example of ethnic inequity highlights the importance to target those most in need. PMID:21423597

    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. PMID:22087327

    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 < 0.01), small-world topology (P < 0.01) and interhemispheric FC (P < 0.01). Computational analysis further showed that developmental changes involved an increase in integration capacity of the connectivity network as a whole. Taken together, we conclude that hallmark organizational structures of the human connectome are present before term birth and subject to early development.

  8. Late-onset neonatal sepsis: recent developments.

    2015-05-01

    The incidence of neonatal late-onset sepsis (LOS) is inversely related to the degree of maturity and varies geographically from 0.61% to 14.2% among hospitalised newborns. Epidemiological data on very low birth weight infants shows that the predominant pathogens of neonatal LOS are coagulase-negative staphylococci, followed by Gram-negative bacilli and fungi. Due to the difficulties in a prompt diagnosis of LOS and LOS-associated high risk of mortality and long-term neurodevelopmental sequelae, empirical antibiotic treatment is initiated on suspicion of LOS. However, empirical therapy is often inappropriately used with unnecessary broad-spectrum antibiotics and a prolonged duration of treatment. The increasing number of multidrug-resistant Gram-negative micro-organisms in neonatal intensive care units (NICU) worldwide is a serious concern, which requires thorough and efficient surveillance strategies and appropriate treatment regimens. Immunological strategies for preventing neonatal LOS are not supported by current evidence, and approaches, such as a strict hygiene protocol and the minimisation of invasive procedures in NICUs represent the cornerstone to reduce the burden of neonatal LOS.

    Introduction Ethanol has been used for years in neonatal and infant liquid medications, yet the pharmacokinetics, pharmacodynamics, and safety of ethanol in this vulnerable population have not been well characterized. The purpose of this review is to raise awareness of ethanol use as an excipient in neonatal and infant medications and to provide insight, based on the available evidence, into clearance rates of ethanol in babies. We also discuss ethanol pharmacokinetics in adults, theoretical pharmacokinetic changes in neonates and infants as it may apply to ethanol disposition, and case reports involving ethanol exposure in neonates and infants. Materials and methods This study was a narrative review in which relevant papers were selected using databases and scientific search engines such as PubMed with the key words ethanol, infant, and newborninfant. Results It remains unclear what ethanol exposure is safe for neonates and infants. The Food and Drug Administration and American Academy of Pediatrics have both taken action, by either setting limits of ethanol content in over-the-counter medications or by recommending restricted exposure to ethanol-containing pediatric formulations. Conclusions Until the short- and long-term health effects of chronic ethanol administration can be further characterized, ethanol-containing medications should be used with caution. PMID:25379066

    Patient: Male, Newborn Final Diagnosis: Accidental methylergonovine poisoning Symptoms: Respiratory distress Medication: — Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Diagnostic/therapeutic accidents Background: Methylergonovine is an ergot alkaloid used to treat post-partum hemorrhage secondary to uterine atony. Mistaking methylergonovine for vitamin K with accidental administration to the neonate is a rare iatrogenic illness occurring almost exclusively in the delivery room setting. Complications of ergot alkaloids in neonates include respiratory depression, seizures, and death. Case Report: A term infant was inadvertently given 0.1 mg of methylergonovine intramuscularly in the right thigh. The error was only noted when the vial of medication was scanned, after administration, identifying it as methylergonovine rather than vitamin K. The local poison center was notified, and the infant was transferred to the neonatal intensive care unit for observation. Two hours after transfer, the infant was noted to have oxygen desaturations and required oxygen via nasal cannula. Supplemental oxygen was continued for 4 hours until the neonate was able to maintain normal oxygen saturations in room air. Feeding was started by 10 hours of life, and the infant was discharged home in good condition after a 72-hour stay without further complications. Conclusions: Because of the potential for serious adverse events, vigilance is required to prevent accidental administration of methylergonovine to the neonate as a result of possible confusion with vitamin K in the early post-partum period.

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

    Neonatal sepsis is one of the most fulminating conditions in neonatal intensive care units. Antipathogen and supportive care are administered routinely, but do not deliver satisfactory results. In addition, the efforts to treat neonatal sepsis with anti-inflammatory agents have generally shown to be futile. The accumulating data imply that intracellular redox changes intertwined into neonatal sepsis redox cycle represent the main cause of dysfunction of mitochondria and cells in neonatal sepsis. Our aim here is to support the new philosophy in neonatal sepsis treatment, which involves the integration of mechanisms that are responsible for cellular dysfunction and organ failure, the recognition of the most important targets, and the selection of safe agents that can stop the neonatal sepsis redox cycle by hitting the hot spots. Redox-active agents that could be beneficial for neonatal sepsis treatment according to these criteria include lactoferrin, interleukin 10, zinc and selenium supplements, ibuprofen, edaravone, and pentoxifylline.

    This study is intended to assess neonatal risk of malnutrition owed to maternal energy intake lower than 2000 kcal/day among Zairian primiparae. Ninety-eight mother-neonate couples were classified according to the level of maternal energy intake. Neonatal albuminemia which previously showed itself as neonatal nutritional marker served for grouping neonates. Possibility of reaching optimal albuminemia value (29,34 g/l) was assessed according to different maternal energy profiles, using U-test and Chi 2. When maternal intake is lower than 2000 kcal/day, neonatal optimum is reached in 26% of cases; when maternal recommendation is lowered to 1675,21 kcal/day, neonatal optimum is reached in 63,43% of cases; with 2000 kcal/day as recommendation, this rate rises up to 71,4%. Under 2000 kcal/day neonatal risk of malnutrition is thus very high.

    Sepsis remains a leading cause of mortality among neonates, especially in developing countries. Most cases of neonatal sepsis are attributed to Escherichia coli and other members of the Enterobacteriaceae family. Shewanella algae (S. algae) is a gram-negative saprophytic bacillus, commonly associated with the marine environment, which has been isolated from humans. Early onset neonatal sepsis caused by S. algae is uncommon. We report a case of S. algae blood stream infection in a newborn with early onset neonatal sepsis.

    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.

    Congenital cytomegalovirus (CMV) remains a leading cause of disability in children. Understanding the pathogenesis of infection from the mother via the placenta to the neonate is crucial if we are to produce new interventions and provide supportive mechanisms to improve the outcome of congenitally infected children. In recent years, some major goals have been achieved, including the diagnosis of primary maternal CMV infection in pregnant women by using the anti-CMV IgG avidity test and the diagnosis and prognosis of foetal CMV infection by using polymerase chain reaction real-time tests to detect and quantify the virus in amniotic fluid. This review summarises recent advances in our understanding and highlights where challenges remain, especially in vaccine development and anti-viral therapy of the pregnant woman and the neonate. Currently, no therapeutic options during pregnancy are available except those undergoing clinical trials, whereas valganciclovir treatment is recommended for congenitally infected neonates with moderately to severely symptomatic disease.

    2016-01-01

    The ovary of neonatal nonhuman primates contains the highest number of immature oocytes, but its cryopreservation has not yet been sufficiently investigated in all life stages. In the current study, we investigated cryodamage after vitrification/warming of neonatal ovaries from a nonhuman primate, the common marmoset (Callithrix jacchus). A Cryotop was used for cryopreservation of whole ovaries. The morphology of the vitrified/warmed ovaries was found to be equivalent to that of fresh ovaries. No significant difference in the number of oocytes retaining normal morphology per unit area in histological sections was found between the two groups. In an analysis of dispersed cells from the ovaries, however, the cell viability of the vitrified/warmed group tended to be decreased. The results of a comet assay showed no significant differences in DNA damage. These results show that cryopreservation of neonatal marmoset ovaries using vitrification may be useful as a storage system for whole ovaries. PMID:26876597

    2016-11-01

    Neonatal immune thrombocytopenia represent less than 5% of cases of early thrombocytopenia (early-onset<72hours post-delivery). As in adults, thrombocytopenia in neonates is defined as a platelet count less than 150G/L. They are either auto- or allo-immune. Thrombocytopenia resulting from transplacental passage of maternal antibodies directed to platelet membrane glycoproteins can be severe. The major complication of severe thrombocytopenia is bleeding and particularly intra-cranial haemorrhage and neurologic sequelea following. However, auto- and allo-immune thrombocytopenia have very different characteristics including the treatment management. In fact, this treatment is based on platelet transfusion associated or not to intravenous immunoglobulin administration. The purpose of this article is to remind platelet transfusion's place in neonatal immune thrombocytopenia in terms of recently published French guidelines and international practices.

    A census of activity and staff levels in 1996 was conducted in UK neonatal units and achieved a 100% response from 246 units. Among the 186 neonatal intensive care units, the median (interquartile range) number of total cots was 18(14−22); level 1 intensive care cots 4(2−6); total admissions 318(262−405); very low birthweight admissions 40(28−68); and the number ventilated or given CPAP by endotracheal tube 52(32−83). Forty six (25%) intensive care units lacked the recommended minimum of one consultant with prime responsibility for neonatal medicine. As a conservative estimate 79% of intensive care units had a lower nursing provision than that recommended in previously published guidelines. There was substantial variation in activity and staffing levels among units.

    PubMed Central

    1985-01-01

    Indices of thyroid function were measured in 229 healthy term neonates at birth and at 5, 10, and 15 days of age. Results were analysed to assess whether maternal diabetes mellitus, toxaemia of pregnancy, intrapartum fetal distress, duration of labour, method of delivery, asphyxia at birth, race, sex, birthweight, birth length, head circumference, or method of feeding influenced any index. Thyroxine, the free thyroxine index, and free thyroxine concentrations at birth correlated with birthweight. Method of delivery influenced mean thyroxine and free thyroxine index values at birth and at age 5 days. Mean values of triiodothyronine, reverse triiodothyronine, thyroxine binding globulin, and thyroid stimulating hormone were not affected by any of the perinatal factors studied. Birthweight and perhaps method of delivery should be taken into account when interpreting neonatal thyroxine parameters but determination of thyroid stimulating hormone as a screen for congenital hypothyroidism in healthy term neonates circumvents these considerations.

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

  2. Oxidative stress, phototherapy and the neonate.

    PubMed

    2000-11-01

    Phototherapy is the most widely used form of therapy for unconjugated hyperbilirubinaemia. Its non-invasive nature and few side effects reported earlier have led to the assumption that it is innocuous. Recent research has revealed that phototherapy is a photodynamic stress and can induce lipid peroxidation. There is increasing evidence that many severe diseases of the neonate are caused by oxidative injury and lipid peroxidation. In the present communique, we review the oxidative susceptibility of the neonate and the evidence now available that phototherapy induces oxidative stress. Although intensive phototherapy (up to 40 mwatt/cm2/nm) has been reported to be increasingly effective, a little caution, we believe is warranted, till more definite data in the human neonate, help resolve the issue.

  3. Pulmonary surfactant for neonatal respiratory disorders.

    PubMed

    Merrill, Jeffrey D; Ballard, Roberta A

    2003-04-01

    Surfactant therapy has revolutionized neonatal care and is used routinely for preterm infants with respiratory distress syndrome. Recent investigation has further elucidated the function of surfactant-associated proteins and their contribution toward surfactant and lung immune defense functions. As the field of neonatology moves away from intubation and mechanical ventilation of preterm infants at birth toward more aggressive use of nasal continuous positive airway pressure, the optimal timing of exogenous surfactant therapy remains unclear. Evidence suggests that preterm neonates with bronchopulmonary dysplasia and prolonged mechanical ventilation also experience surfactant dysfunction; however, exogenous surfactant therapy beyond the first week of life has not been well studied. Surfactant replacement therapy has been studied for use in other respiratory disorders, including meconium aspiration syndrome and pneumonia. Commercial surfactant preparations currently available are not optimal, given the variability of surfactant protein content and their susceptibility to inhibition. Further progress in the treatment of neonatal respiratory disorders may include the development of "designer" surfactant preparations.

  13. Cotrimoxazole and neonatal kernicterus: a review.

    PubMed

    Thyagarajan, Baskaran; Deshpande, Sharad S

    2014-04-01

    Sulfamethoxazole (SMX) and trimethoprim (TMP) individually and a combination known as cotrimoxazole (SMX-TMP) are widely used for the treatment of protozoan and bacterial infections. SMX-TMP is also one of the widely used antibiotics administered orally in neonates, along with gentamicin injection, for treating pneumonia and sepsis by home-based healthcare providers in Asian countries. Although the use of this drug has successfully reduced neonate mortality, there is a concern for it causing neurotoxicity. Previous clinical studies with sulfisoxazole have demonstrated occurrence of kernicterus in neonates. This sulfonamide is thought to displace bilirubin from its albumin-binding sites in plasma leading to an elevation of plasma bilirubin, which crosses the blood-brain barrier, reaches central neurons to cause kernicterus. We performed an extensive review of clinical and animal studies with cotrimoxazole, which showed no reported incidences of kernicterus with SMX-TMP use in neonates. EndNote, BasicBiosis, Embase, PubMed and Toxline database searches were conducted using specific keywords yielding 74 full-length articles relevant to the review. This review has taken into account various factors, including the disease itself, direct effects of the drug and its metabolism through conjugation and acetylation through a thorough review of the literature to examine the potentials of SMX-TMP to cause kernicterus in neonates. SMX-TMP in oral doses administered to neonates for 7-10 days is unlikely to cause kernicterus. Also, this review recommends warranting the need of future studies using animal models and clinical studies in humans to address SMX-TMP toxicity.

    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.

    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.

    2010-06-01

    The potential for genetic variation to modulate neonatal hyperbilirubinemia risk is increasingly being recognized. In particular, polymorphisms across three genes involved in bilirubin production and metabolism [glucose-6-phosphate dehydrogenase (G6PD), uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1), and solute carrier organic anion transporter polypeptide 1B1 (SLCO1B1)] may interact with each other and/or environmental contributors to produce significant hyperbilirubinemia. Variant gene co-expression including compound and synergistic heterozygosity enhances hyperbilirubinemia risk, contributing to the etiologic heterogeneity and complex nature of neonatal jaundice.

    Neonatal acute liver failure is a rare, very severe disease with a high rate of mortality. It is clinically and etiologically different from acute liver failure seen in older children and adults. Coagulopathy with an international normalized ratio ≥ 3 is the critical parameter that defines it. The most common causes are fetal alloimmune hepatitis, previously called neonatal hemochromatosis, viral infections, metabolic disorders, and hemophagocytic lymphohistiocytosis. There is a group of treatable diseases that require a very early diagnosis for the prescription of an adequate treatment. Patients should be immediately referred to a specialized facility where pediatric liver transplantation is available to implement such therapeutic alternative, if indicated.

    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.

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. PMID:27458596

    Listeria monocytogenes was isolated in two neonates born consecutively in the same hospital in France. The isolates had indistinguishable pulsed-field electrophoresis profiles. Retrospective epidemiological investigations found no evidence of a food-borne or environmental source.

    Neonatal immune hyperthyroidism is a rare but potentially fatal condition. It occurs in 1–5% of infants born to women with Graves’ disease (GD). In most of the cases it is due to maternal antibodies transferred from the mother into the fetal compartment, stimulating the fetal thyroid by binding thyrotropin (thyroid-stimulating hormone, TSH) receptor. We present a case of neonatal thyrotoxicosis due to maternal GD detected at 25 days of age and discuss the potential pitfalls in the diagnosis. PMID:25750228

    2013-09-01

    Nociceptive pathways are functional following birth. In addition to physiological and behavioral responses, neurophysiological measures and neuroimaging evaluate nociceptive pathway function and quantify responses to noxious stimuli in preterm and term neonates. Intensive care and surgery can expose neonates to painful stimuli when the developing nervous system is sensitive to changing input, resulting in persistent impacts into later childhood. Early pain experience has been correlated with increased sensitivity to subsequent painful stimuli, impaired neurodevelopmental outcomes, and structural changes in brain development. Parallel preclinical studies have elucidated underlying mechanisms and evaluate preventive strategies to inform future clinical trials.

    The technique for gavage administration to rat nurslings was improved to allow determination of the direct effects of chemical substances in the nurslings. Rat neonates were treated with distilled water from postnatal day 1 through 20 using this technique. The viability of neonates during the administration period was comparable to that of untreated neonates. No adverse effects of this technique on the development of neonates were found, and no histological alterations of the esophagus or pharynx. Therefore, we conclude that use of our improved gavage administration method will contribute to ensuring successful neonatal development and thus allowing accurate assessment of the toxicological effects of test compounds on rat nurslings.

    Introduction Consumption of cotoneaster may reduce neonatal jaundice. Aim Hence this study was undertaken to determine the effect of mothers’ cotoneaster consumption on treatment of their neonates’ jaundice. Materials and Methods In this randomized clinical trial study, 120 neonates with jaundice referred to a hospital in southwest Iran were enrolled by nonprobability sampling and divided randomly into four groups. In the first group both mothers and neonates received cotoneaster; in the second group only mothers; in the third group only neonates; and in the fourth group the neonates received distilled water as placebo. Phototherapy was done under the same condition for all neonates. Results The reduction of bilirubin was significantly higher in treatment groups compared to control group (p<0.05). Bilirubin in the group of neonates whose mothers consumed cotoneaster was less compared to control group at 24 and 36 hours (p<0.05) and the highest reduction in bilirubin was observed in the first group. The mean duration of hospitalization was longer for the control group (p<0.05). Conclusion Consumption of cotoneaster by both mothers and neonates caused a decrease in neonatal jaundice more rapidly compared to other groups and decreased the duration of hospitalization. Cotoneaster consumption by mothers, neonates, or both may be useful in treatment of neonatal jaundice. PMID:27190910

    Atlas construction generally includes first an image registration step to normalize all images into a common space and then an atlas building step to fuse the information from all the aligned images. Although numerous atlas construction studies have been performed to improve the accuracy of the image registration step, unweighted or simply weighted average is often used in the atlas building step. In this article, we propose a novel patch-based sparse representation method for atlas construction after all images have been registered into the common space. By taking advantage of local sparse representation, more anatomical details can be recovered in the built atlas. To make the anatomical structures spatially smooth in the atlas, the anatomical feature constraints on group structure of representations and also the overlapping of neighboring patches are imposed to ensure the anatomical consistency between neighboring patches. The proposed method has been applied to 73 neonatal MR images with poor spatial resolution and low tissue contrast, for constructing a neonatal brain atlas with sharp anatomical details. Experimental results demonstrate that the proposed method can significantly enhance the quality of the constructed atlas by discovering more anatomical details especially in the highly convoluted cortical regions. The resulting atlas demonstrates superior performance of our atlas when applied to spatially normalizing three different neonatal datasets, compared with other start-of-the-art neonatal brain atlases.

    Advances in ventilatory management of respiratory distress in the newborn have made dramatic strides during the last decade. Innovative treatments such as PTV, HFV, liquid ventilation, and NO therapy are just beginning to have an impact on the care of neonates in the NICU. These treatment modalities should continue to have an effect on the care of the newborn infant well into the future.

  11. Detecting Neonatal Seizures With Computer Algorithms.

    2016-10-01

    It is now generally accepted that EEG is the only reliable way to accurately detect newborn seizures and, as such, prolonged EEG monitoring is increasingly being adopted in neonatal intensive care units. Long EEG recordings may last from several hours to a few days. With neurophysiologists not always available to review the EEG during unsociable hours, there is a pressing need to develop a reliable and robust automatic seizure detection method-a computer algorithm that can take the EEG signal, process it, and output information that supports clinical decision making. In this study, we review existing algorithms based on how the relevant seizure information is exploited. We start with commonly used methods to extract signatures from seizure signals that range from those that mimic the clinical neurophysiologist to those that exploit mathematical models of neonatal EEG generation. Commonly used classification methods are reviewed that are based on a set of rules and thresholds that are either heuristically tuned or automatically derived from the data. These are followed by techniques to use information about spatiotemporal seizure context. The usual errors in system design and validation are discussed. Current clinical decision support tools that have met regulatory requirements and are available to detect neonatal seizures are reviewed with progress and the outstanding challenges are outlined. This review discusses the current state of the art regarding automatic detection of neonatal seizures.

    Magnetoencephalography is a biomagnetic technique with outstanding potential for neurodevelopmental studies. In this work, we have used MEG to determinate if newborns can discriminate between different stimuli during the first few months of life. Five neonates were stimulated during several minutes with auditory stimulation. The results suggest that the newborns are able to discriminate between different stimuli despite their early age.

    2007-02-01

    Manganese (Mn) is an essential trace metal found in all tissues, and it is required for normal amino acid, lipid, protein, and carbohydrate metabolism. While Mn deficiency is extremely rare in humans, toxicity due to overexposure of Mn is more prevalent. The brain appears to be especially vulnerable. Mn neurotoxicity is most commonly associated with occupational exposure to aerosols or dusts that contain extremely high levels (>1-5 mg Mn/m(3)) of Mn, consumption of contaminated well water, or parenteral nutrition therapy in patients with liver disease or immature hepatic functioning such as the neonate. This review will focus primarily on the neurotoxicity of Mn in the neonate. We will discuss putative transporters of the metal in the neonatal brain and then focus on the implications of high Mn exposure to the neonate focusing on typical exposure modes (e.g., dietary and parenteral). Although Mn exposure via parenteral nutrition is uncommon in adults, in premature infants, it is more prevalent, so this mode of exposure becomes salient in this population. We will briefly review some of the mechanisms of Mn neurotoxicity and conclude with a discussion of ripe areas for research in this underreported area of neurotoxicity.

  17. Paracetamol overdose in a preterm neonate

    PubMed Central

    Isbister, G; Bucens, I; Whyte, I

    2001-01-01

    The first oral overdose of paracetamol in a neonate is reported. A 55 day old neonate, born 29 weeks premature, was accidentally given 136 mg/kg paracetamol. Treatment was with activated charcoal, supportive care, and N-acetylcysteine. There was no biochemical evidence of hepatotoxicity, and no long term sequelae. After modelling of the data, the following pharmacokinetic variables were calculated: absorption half life (tabs), 0.51 hours; volume of distribution (V/Foral), 0.80 litres/kg; clearance (CL/Foral), 0.22 litres/h; they were consistent with population pharmacokinetic studies. The increased plasma half life (Tβ) of 5.69 hours thus reflected normal slower metabolism in infants, rather than toxicity. The toxicity of paracetamol in neonates is unclear, but appears to be low because of slow oxidative metabolism and rapid glutathione synthesis. In an overdose, estimates of toxicity can be made from dose and Tβ in neonates, or from maternal toxicity in transplacental poisoning. Treatment includes N-acetylcysteine and supportive care, with activated charcoal for oral poisoning.

    The fetoplacental interface plays a unique role in pathologies of the fetus and neonate, and is increasingly being recognized for effects on fetal and neonatal development that resonate into adulthood. In this review, we will use several exemplary disorders involving each of the 3 types of blood cells to explore the effect of perinatal insults on subsequent development of the affected cell line. We will present new data regarding outcomes of infants treated prenatally for fetal and neonatal alloimmune thrombocytopenia (FNAIT) and contrast these with outcomes of infants affected by hemolytic disease of the fetus and newborn. We also will explore the differences between FNAIT and passively transferred antibodies, as seen in maternal idiopathic thrombocytopenic purpura. Neonatal hemochromatosis is an example of a disease that previously was largely fatal, but whose newly discovered etiology as an immune-mediated perinatal disorder has resulted in development of highly effective treatment. Finally, we will examine the interplay between lymphopoiesis and the placenta in an effort to further explore the phenomenon of neutropenia in preeclampsia, whose etiology remains unknown.

    Introduccion. Durante el nacimiento, ocurren cambios fisiologicos en practicamente todos los organos del niño, incluyendo el sistema nervioso central. En esta fase de transicion, es posible un cierto grado de hipoxemia, en general bien tolerado por el neonato. Sin embargo, si la hipoxia neonatal es muy intensa y continuada, puede instalarse una encefalopatia neonatal, lo que caracteriza una situacion critica para el recien nacido. Su abordaje adecuado es imprescindible para garantizar un buen pronostico a largo plazo. Desarrollo. Se actualizan las informaciones acerca de la hipoxia neonatal y se revisan publicaciones recientes acerca de los avances en su abordaje a traves de la medicina basada en evidencias. Conclusiones. La encefalopatia neonatal se puede clasificar desde el punto de vista clinico en tres niveles de intensidad. Usualmente, los casos leves tienen un buen pronostico, los casos de intensidad moderada tienen un 30% de posibilidad de secuelas y los de intensidad grave tienen mas del 70% de mortalidad, pero practicamente todos los supervivientes tendran secuelas. Los avances ocurrieron en dos areas: en el diagnostico, con nuevas tecnicas de EEG y RM, y en el tratamiento, con la aparicion de la hipotermia terapeutica. Existe la posibilidad de un uso futuro para la terapia con celulas madre. El pronostico depende de la clasificacion clinica, de los datos de neuroimagen y del EEG.

    Objectives 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. Methods 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. Results 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. Conclusion The incubator provides a safe, quiet environment for neonates during transport and imaging, at low cost. PMID:22167517

    Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse neonatal survival and is estimated to impact between 0.4 and 5% of pregnancies worldwide. Here we show that maternal cholestasis (due to Abcb11 deficiency) produces neonatal death among all offspring within 24 h of birth due to atelectasis-producing pulmonary hypoxia, which recapitulates the neonatal respiratory distress of human ICP. Neonates of Abcb11-deficient mothers have elevated pulmonary bile acids and altered pulmonary surfactant structure. Maternal absence of Nr1i2 superimposed on Abcb11 deficiency strongly reduces maternal serum bile acid concentrations and increases neonatal survival. We identify pulmonary bile acids as a key factor in the disruption of the structure of pulmonary surfactant in neonates of ICP. These findings have important implications for neonatal respiratory failure, especially when maternal bile acids are elevated during pregnancy, and highlight potential pathways and targets amenable to therapeutic intervention to ameliorate this condition.

    2015-01-01

    Hypotension is common in low birth weight neonates and less common in term newborns and is associated with significant morbidity and mortality. Determining an adequate blood pressure in neonates remains challenging for the neonatal nurse because of the lack of agreed-upon norms. Values for determining norms for blood pressure at varying gestational and postnatal ages are based on empirical data. Understanding cardiovascular pathophysiology, potential causes of hypotension, and assessment of adequate perfusion in the neonatal population is important and can assist the neonatal nurse in the evaluation of effective blood pressure. This article reviews cardiovascular pathophysiology as it relates to blood pressure and discusses potential causes of hypotension in the term and preterm neonate. Variation in management of hypotension across centers is discussed. Underlying causes and pathophysiology of hypotension in the neonate are described.

    It is unclear if neonatal tetralogy of Fallot repair offers better outcomes compared to repair later in infancy. We therefore conducted a meta-analysis comparing outcomes of neonatal and non-neonatal repair. Manuscripts were identified and reviewed for quality and bias with favorably scored manuscripts being included in the final meta-analysis. Several perioperative and postoperative variables were compared. A total of 8 studies with 3858 patients were included in the analysis. Of these patients, 19% underwent neonatal repair. Neonatal repair was associated with increased mortality, longer intensive care unit stays, and longer total hospital length of stay.

    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.

    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.

    The neonatal period is considered to be essential for neurodevelopment and wellbeing throughout the life span, yet little is known about brain-behavior relationships in the neonatal period. The aim of this study was to evaluate the association between neonatal sensory-motor regulation and white-matter (WM) integrity of major fiber tracts in the neonatal period. We hypothesized that WM integrity of sensory-motor systems would predict neurobehavioral maturation during the first month of life. Forty-nine premature neonates underwent magnetic-resonance-imaging at term. Diffusion-tensor-imaging analysis was performed in major WM tracts along with repeated neonatal neurobehavioral evaluations assessing sensory reactivity and motor regulation. Difficulties in one or more behavioral sub-category, mostly in auditory and visual attention, hypotonicity and jitteriness, were documented in 78.3% infants at term. Sixty-six percent of infants experienced difficulties, mostly in auditory attention, head-neck control, hypotonicity and motor asymmetry, at 44 weeks. Attention difficulties were associated with reduced integrity of cerebral and superior cerebellar peduncles; while tonicity was associated with reduced integrity of the corpus-callosum and inferior-posterior tracts. Overall, results showed that early maturing tracts were related with the degree of typicality of sensory reactivity status while late maturing tracts were related with the degree of typicality of tonic regulation. WM integrity and maturation factors explained 40.2% of the variance in neurobehavior at 44 weeks. This study suggests that in preterm neonates, deviant sensory-motor reactivity can be detected very early in development in manners that are related to lower integrity/maturational level of early and late maturing fiber tracts.

  12. Unilateral neonatal cerebral infarction in full term infants

    1997-01-01

    AIMS—To determine the prevalence of unilateral neonatal cerebral infarction in infants born at 32 weeks gestation and above; to describe the clinical course, imaging results, and outcome of neonatal cerebral infarction; and to investigate possible aetiology.
METHODS—Twelve cases of unilateral neonatal cerebral infarction were identified from neonatal unit records for the years 1987-93. Each case was matched with two controls.
RESULTS—All cases of neonatal cerebral infarction occurred in full term infants. The prevalence was around 1 in 4000, and neonatal cerebral infarction was found in 12% of infants presenting with neonatal seizures. Cerebral ultrasound scans failed to demonstrate lesions seen by computed tomography in nine of 12 cases. Cases were more likely than controls to require assisted ventilation for resuscitation at birth (OR 7.0, 95% confidence interval 1.04-53.5), but Apgar scores at 5 minutes were no different. One infant with neonatal cerebral infarction developed a hemiparesis, the other 11 had normal motor development when assessed at 11-60 (median 33) months. None had overt cognitive deficits or persisting seizure disorder.
CONCLUSIONS—Neonatal cerebral infarction is a relatively common cause of neonatal seizures, but the aetiology remains unclear. Parents need to be made aware of possible neurological sequelae, but most cases in this series had a normal outcome.

    Objectives To identify the use and adverse drug reactions associated with azithromycin in neonates. Setting Databases MEDLINE (1948–August 2015), EMBASE (1980–August 2015) and Pubmed (August 2015) were searched for studies on azithromycin in neonates. Participants All studies involving neonates (<28 days old) who have received at least a single dose of azithromycin for which safety was evaluated. Primary and secondary outcome measures The primary outcome was adverse event (AE) associated with use of azithromycin. Use of azithromycin in neonates was the secondary outcome. Results 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). Conclusions Azithromycin significantly reduces the risk of BPD in preterm neonates. The relationship between azithromycin and IHPS requires further investigation. PMID:26656010

    2015-08-01

    Short bowel syndrome (SBS) is a growing problem in the human neonatal population. In infants, SBS is the leading cause of intestinal failure, the state of being unable to absorb sufficient nutrients for growth and development. Neonates with SBS are dependent on long-term parenteral nutrition therapy, but many succumb to the complications of sepsis and liver disease. Research in neonatal SBS is challenged by the ethical limits of studying sick human neonates and the heterogeneous nature of the disease process. Outcomes in SBS vary depending on residual intestinal anatomy, intestinal length, patient age, and exposure to nutrition therapies. The neonatal piglet serves as an appropriate translational model of the human neonate because of similarities in gastrointestinal ontogeny, physiological maturity, and adaptive processes. Re-creating the disease process in a piglet model presents a unique opportunity for researchers to discover novel insights and therapies in SBS. Emerging piglet models of neonatal SBS now represent the entire spectrum of disease seen in human infants. This review aims to contextualize these emerging piglet models within the context of SBS as a heterogeneous disease. We first explore the factors that account for SBS heterogeneity and then explore the suitability of the neonatal piglet as an appropriate translational animal model. We then examine differences between the emerging piglet models of neonatal SBS and how these differences affect their translational potential to human neonates with SBS.

    Blood sampling for a newborn screening test is necessary for all neonates in South Korea. During the heel stick, an appropriate intervention should be implemented to reduce neonatal pain. This study was conducted to identify the effectiveness of kangaroo care (KC), skin contact with the mother, on pain relief during the neonatal heel stick. Twenty-six neonates undergoing KC and 30 control neonates at a university hospital participated in this study. Physiological responses of neonates, including heart rate, oxygen saturation, duration of crying and Premature Infant Pain Profile (PIPP) scores were measured and compared before, during and 1 min and 2 min after heel sticks. The heart rate of KC neonates was lower at both 1 and 2 min after sampling than those of the control group. Also, PIPP scores of KC neonates were significantly lower both during and after sampling. The duration of crying for KC neonates was around 10% of the duration of the control group. In conclusion, KC might be an effective intervention in a full-term nursery for neonatal pain management.

    Background Many neonatal deaths can be prevented globally through effective resuscitation. South Africa (SA) committed towards attaining the Millennium Development Goal 4 (MDG4) set by the World Health Organization (WHO). However, SA’s district hospitals have the highest early neonatal mortality rates. Modifiable and avoidable causes associated with patient-related, administrative and health care provider factors contribute to neonatal mortality. A quality improvement initiative in neonatal resuscitation could contribute towards decreasing neonatal mortality, thereby contributing towards the attainment of the MDG4. Aim The aim of this study was, (1) to explore and describe the existing situation regarding neonatal resuscitation in a district hospital, (2) to develop strategies to sustain a neonatal resuscitation quality improvement initiative and (3) to decrease neonatal mortality. Changes that occurred and the sustainability of strategies were evaluated. Setting A maternity section of a district hospital in South Africa. Methods The National Health Service (NHS) Sustainability Model formed the theoretical framework for the study. The Problem Resolving Action Research model was applied and the study was conducted in three cycles. Purposive sampling was used for the quantitative and qualitative aspects of data collection. Data was analysed accordingly. Results The findings indicated that the strategies formulated and implemented to address factors related to neonatal resuscitation (training, equipment and stock, staff shortages, staff attitude, neonatal transport and protocols) had probable sustainability and contributed towards a reduction in neonatal mortality in the setting. Conclusion These strategies had the probability of sustainability and could potentially improve neonatal outcomes and reduce neonatal mortality to contribute toward South Africa’s’ drive to attain the MDG4.

    Neonatal bacterial meningitis is a common manifestation of late onset neonatal sepsis. Cranial sonography (CRS) has a crucial role in assessment of infants with clinical suspicion of bacterial meningitis as well as follows up of its complications. CRS is performed with high frequency transducer through anterior fontanelle in both coronal and sagittal planes. Various sonographic findings range from echogenic and widened sulci, ventriculomegaly, ventriculitis, hydrocephalus, extra-axial fluid collections, cerebritis and brain abscess. Sonography is extremely beneficial in evaluating intraventricular contents, especially debris and intraventricular septations. Linear high frequency probe along with color Doppler interrogation are of utmost importance in evaluating extra-axial fluid collection and helps differentiating it from benign subarachnoid space enlargement. Due to low cost, easy portability, speed of imaging, no need for sedation and above all lack of ionizing radiation make it superior to other cross sectional imaging, like CT and MRI, in evaluation of these sick neonates. Apart from textbooks, there is paucity of recently available literature on cranial sonographic findings in neonatal meningitis. This article is written with an educational intent to review the spectrum of findings in neonatal meningitis, with stress on findings that will be beneficial in the clinical practice. PMID:28275563

    Purpose The aims of this study were to evaluate the safety and pharmacokinetics of levetiracetam (LEV) in neonates with seizures and to establish a population pharmacokinetics (PPK) model by using the software NONMEM. Methods A retrospective analysis of 18 neonatal patients with seizures, who were treated with LEV, including 151 serum samples, was performed. The mean loading dose was 20 mg/kg, followed by a mean maintenance dose of 29 mg/kg/day. Results Seventeen neonates (94%) had seizure cessation within 1 week and 16 (84%) remained seizure-free at 30 days under the LEV therapy. The mean serum concentration of LEV was 8.7 µg/mL. Eight samples (5%) were found above the therapeutic range. No serious adverse effects were detected. In the PPK analysis for Korean neonates, the half-life was 9.6 hours; clearance, 0.357 L/hr; and volume of distribution, 4.947 L, showing differences from those in adults. Conclusion LEV is a safe and effective option for the treatment of neonatal seizures with careful therapeutic drug monitoring. PMID:28289434

  19. Birthmarks of medical significance in the neonate.

    Birthmarks are commonplace and most pose no significant detriment to health. It is usual for some 'birthmarks' to manifest within the first weeks to months of life and are not necessarily seen at birth. This is attributed in large part to the maturation of neonatal skin and the deepening of skin color over time. With time, increased pigment production in the skin by melanocytes eventually highlight the differences between normal and abnormal hypopigmented and hyperpigmented anomalies of the skin. Birthmarks can be seen as an isolated skin condition or serve as an important diagnostic aid for other more significant disorders. This review details four of the most common birthmarks regularly encountered in the neonatal period by perinatologists, obstetricians and pediatricians. This review emphasizes their medical significance and highlights any associated underlying systemic disease or genetic syndrome.

  20. Teaching antenatal counseling skills to neonatal providers.

    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.

    2016-01-01

    Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods. PMID:27066444

    2006-02-01

    Neonatal spinal cord injury can occur in utero, as well as after either a difficult delivery or a nontraumatic delivery. Spinal cord injury can also be related to invasive nursery procedures or underlying neonatal pathology. Early clinical signs of spinal cord injury that has occurred in utero or at delivery includes severe respiratory compromise and profound hypotonia. Knowledge of risk factors and awareness of symptoms is required for early recognition and appropriate treatment. This article reviews the embryological development of the spinal column highlighting mechanisms of injury and identifying underlying factors that increase the risk of spinal cord injury in newborns. Signs and symptoms of injury, cervical spine immobilization, and the differential diagnosis are discussed. Nursing implications, general prognosis, and research in spinal cord injury are provided.

    2015-01-01

    Neonatal hypoxic ischemic encephalopathy (HIE) is a devastating disease that primarily causes neuronal and white matter injury and is among the leading cause of death among infants. Currently there are no well-established treatments; thus, it is important to understand the pathophysiology of the disease and elucidate complications that are creating a gap between basic science and clinical translation. In the development of neuroprotective strategies and translation of experimental results in HIE, there are many limitations and challenges to master based on an appropriate study design, drug delivery properties, dosage, and use in neonates. We will identify understudied targets after HIE, as well as neuroprotective molecules that bring hope to future treatments such as melatonin, topiramate, xenon, interferon-beta, stem cell transplantation. This review will also discuss some of the most recent trials being conducted in the clinical setting and evaluate what directions are needed in the future. PMID:26389893

  4. Adrenal Hemorrhage in Neonates: Unusual Presentation.

    PubMed

    2015-01-01

    Adrenal hemorrhage (AH) is a relatively uncommon condition in newborns. It may be asymptomatic or may present with flank abdominal mass, anemia, jaundice, or rarely as scrotal bruising or hematoma. We report two cases of AH in neonates; the first presented with scrotal hematoma and the second with adrenal mass associated with hypertension and oliguria, primarily secondary to coincidental renal vein thrombosis. Diagnosis was confirmed by abdominal ultrasound. Patients were managed conservatively with clinical observation and by following hemoglobin and bilirubin levels closely. Both infants were discharged without surgical intervention after several days in the hospital. Clinicians should consider AH when a newborn presents with scrotal bruising or hematoma, unexplained anemia, unexplained jaundice, or flank abdominal mass. Timely ultrasonographic evaluation of both adrenal glands and testes in neonates with scrotal hematoma may spare infants from unnecessary surgical intervention because scrotal hematoma often raises the suspicion of testicular torsion.

    2012-12-01

    The incidence of neonatal early onset sepsis has declined with the widespread use of intrapartum antibiotic therapies, yet early onset sepsis remains a potentially fatal condition, particularly among very low birth-weight infants. Clinical signs of neonatal infection are nonspecific and may be absent in the immediate postnatal period. Maternal and infant clinical characteristics, as well as infant laboratory values, have been used to identify newborns at risk and to administer empiric antibiotic therapy to prevent progression to more severe illness. Such approaches result in the evaluation of approximately 15% of asymptomatic term and late preterm infants and of nearly all preterm infants. The development of multivariate predictive models may provide more accurate methods of identifying newborns at highest risk and allow for more limited newborn antibiotic exposures.

    2007-03-01

    This study focuses on the social and political implications of the substantial expansion of genetic tests and neonatal screening. The introduction of neonatal screening for cystic fibrosis is one of the significant developments that have fuelled debate on their appropriateness. It has raised a series of questions on the pros and cons, the role of evidence in biomedicine, and the articulation between the therapeutic approach and foetal selection. In this respect France provides an ideal research field as it was one of the first countries to generalize this screening, launched in January 2002. Several questions arise: What were the terms of the debate in France and their underlying logics? How was consensus reached? More generally, what does this screening tell us about policies on life forms today?

    2016-01-01

    Despite concerted international efforts, mortality from neonatal infections remains unacceptably high in some areas of the world, particularly for premature infants. Recent developments in flow cytometry and next-generation sequencing technologies have led to major discoveries over the past few years, providing a more integrated understanding of the developing human immune system in the context of its microbial environment. We review these recent findings, focusing on how in human newborns incomplete maturation of the immune system before a full term of gestation impacts on their vulnerability to infection. We also discuss some of the clinical implications of this research in guiding the design of more-accurate age-adapted diagnostic and preventive strategies for neonatal sepsis. PMID:26993220

    1986-01-01

    We report 37 patients ranging in age from 1 month to 14 years treated for intestinal malrotation during a five year period. The main presenting features consisted of intermittent attacks of vomiting (15 patients), failure to thrive (seven), and recurrent colicky abdominal pain (seven). The diagnosis was confirmed by gastrointestinal contrast studies in all but three patients. A standard Ladd's procedure comprised the definitive surgical treatment. We emphasise the poor nutritional state at the time of operation (49% of the cases were on or below the third centile). In contrast with neonatal presentation, volvulus of the midgut occurred in only five patients (14%) compared with 68% in neonates with malrotation. There were two deaths in the series. Ninety four per cent of the remaining patients responded favourably to the operative procedure. Malrotation should be considered in the differential diagnosis of a wide variety of symptoms and should be treated promptly once the diagnosis has been confirmed. PMID:3740908

    Hemangioma is the most common vascular tumor of infancy; presentation is often as cutaneous infantile hemangioma (IH). Cutaneous hemangioma is a clinical diagnosis. Most IHs follow a benign course, with complete involution without treatment in the majority of cases. Visceral hemangioma often involves the liver and manifests as a life-threatening disorder. Hepatic hemangiomas may be associated with high output cardiac failure, coagulopathy, and hepatomegaly which generally develop between 1 and 16 weeks of age. Mortality has been reportedly high without treatment. We report a rare case of a male infant with neonatal hemangiomatosis with diffuse peritoneal involvement, which mimicked a malignant-looking tumor on imaging, and discuss therapeutic options and efficacy. Propranolol is efficacious for IH but generally not useful for other forms of vascular hemangiomas, tumors, and malformations. In our case of neonatal peritoneal hemangiomatosis, propranolol appears to have halted the growth and possibly expedite the involution of the hemangiomatosis without other treatments.

    Cardiac emergencies in children are not infrequent. Early recognition and management are essential to save life and prevent any comorbidity. The presentation of cardiac emergencies and etiologies is variable depending on the age of child at the time of presentation and type of cardiac lesion. Cyanotic and noncyanotic congenital heart diseases are the main causes in neonates and infants. Acquired heart diseases and dysrhythmia are more common causes for cardiac emergencies in toddler and childhood. In this review, we discuss the most common causes for cardiac emergencies in neonates and young infants highlighting important points in the presentation and management that are essential for early recognition and timely management of infants presenting with these conditions.

    Persistent hyperinsulinemic hypoglicemia of the neonate is a rare heterogenous disease (clinically, histologically, metabolically and genetically), which is characterized by inadequatly high insuline rates in the presence of severe hypoglicemia. Hyperinsulinism, rather a syndrome than a disease, of which the main metabolic feature is hypoglicemia and decreased concentration of free fatty acids and ketones in serum (insulin inhibits lypolisis and synthesizes ketonic bodies), presents a major diagnostic and therapeutic chalenge. The disease is often followed by brain atrophy contributed by the attacks of hypoglicemia. It is inherited as an autosomally recessive and autosomally dominant disease. The genetic defects is located on the short arm of the chromosome 11. The authors report a successfully applied conservative treatment in a neonate with persistent hyperinsulinemic hypoglicemia.

    A case of neonatal Marfan syndrome is presented. The patient was noted to have cardiomegaly and tricuspid regurgitation on antenatal ultrasound scan. She was born with long, slender fingers and toes, an aged appearance and non-paralytic hypotonia. Echocardiogram revealed a dilated right atrium, right ventricle, dysplastic tricuspid valve and severe tricuspid regurgitation. She subsequently died of severe heart failure. Post-mortem examination showed the pathological features of lobar emphysema and cystic medial necrosis of the aorta. These features supported the diagnosis of neonatal Marfan syndrome. Nucleotide sequencing showed substitution of G by A at codon 1032 in exon 25 located in the long arm of chromosome 15. This resulted in the substitution of a cysteine by a tyrosine. A de novo mutation is suggested by the absence of affected family members.

    Cerebral palsy is often associated with spasticity. This study was designed to evaluate the effect of oral baclofen in hypertonic neonates. Retrospective chart review of patients treated with oral baclofen (identified by means of pharmacy records) during a 3-year period was undertaken. Data on muscle tone evaluated using the Modified Ashworth Scale scores were analyzed for effectiveness. Twenty-nine infants had Modified Ashworth Scale scores before and during oral baclofen therapy. The study infants had a mean gestational age of 25.7 ± 1.9 weeks. Baclofen was started at a postnatal age of 86.4 ± 33.6 days. Comparison of Modified Ashworth Scale scores after initiation of therapy to prebaclofen scores demonstrated no significant decrease in muscle tone. Results of our study show that there is no overall decrease in tone during oral baclofen therapy in hypertonic preterm neonates.

    Background: Neonates and children differ from adults in physiology, pharmacologic responses to drugs, epidemiology, and long-term consequences of thrombosis. This guideline addresses optimal strategies for the management of thrombosis in neonates and children. Methods: The methods of this guideline follow those described in the Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. Results: We suggest that where possible, pediatric hematologists with experience in thromboembolism manage pediatric patients with thromboembolism (Grade 2C). When this is not possible, we suggest a combination of a neonatologist/pediatrician and adult hematologist supported by consultation with an experienced pediatric hematologist (Grade 2C). We suggest that therapeutic unfractionated heparin in children is titrated to achieve a target anti-Xa range of 0.35 to 0.7 units/mL or an activated partial thromboplastin time range that correlates to this anti-Xa range or to a protamine titration range of 0.2 to 0.4 units/mL (Grade 2C). For neonates and children receiving either daily or bid therapeutic low-molecular-weight heparin, we suggest that the drug be monitored to a target range of 0.5 to 1.0 units/mL in a sample taken 4 to 6 h after subcutaneous injection or, alternatively, 0.5 to 0.8 units/mL in a sample taken 2 to 6 h after subcutaneous injection (Grade 2C). Conclusions: The evidence supporting most recommendations for antithrombotic therapy in neonates and children remains weak. Studies addressing appropriate drug target ranges and monitoring requirements are urgently required in addition to site- and clinical situation-specific thrombosis management strategies.

    Background: Echocardiography is an investigation that is being used increasingly on the neonatal unit. There is some controversy as to whether this service can be provided safely and effectively by neonatologists or whether it should only be performed by paediatric cardiologists. Aims: To describe (a) the indications for an echocardiogram, (b) the yield and range of positive findings, (c) the resulting changes in clinical management, and (d) the reliability of echocardiography in the hands of neonatologists when it is performed on the neonatal unit. Methods: Information about all echocardiograms performed on the neonatal unit was collected prospectively. Indications for performing echocardiography, echocardiographic findings, and any resulting changes in clinical management were determined. The concordance of findings in infants who underwent echocardiograms performed by both a neonatologist and a paediatric cardiologist was described. Results: A total of 157 echocardiograms were performed in 82 infants. Echocardiography identified 44 infants with a structural cardiac abnormality and a further 17 infants with a trivial abnormality. In addition, 13 babies were found to have an important functional abnormality. Echocardiography prompted a specific change in clinical management in 64 (78%) babies. In 31 of the 38 infants who had paired scans performed, there was complete concordance between the two examinations. No infants had scans that were completely different. Some discrepancy was identified in seven infants, but this did not prevent appropriate immediate clinical management. Conclusions: Echocardiography on the neonatal unit has a high yield for the diagnosis of structural and functional cardiac abnormalities, often results in a change in clinical management, and can be a reliable tool in the hands of neonatologists.

    2015-06-01

    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.

    Neonates and infants in the neonatal intensive care unit suffer significant morbidity when intravenous (IV) catheters infiltrate. The underreporting of adverse events through hospital voluntary reporting systems, such as ours, can complicate the monitoring of low incidence events, like IV infiltrates. Based on severe cases of IV infiltrates observed in our neonatal intensive care unit, we attempted to improve the detection of all infiltrates and reduce the incidence of Stage 4 infiltrates. We developed, and initiated the use of, an evidence-based guideline for the improved surveillance, prevention, and management of IV infiltrates, with corresponding educational interventions for faculty and staff. We instituted the use of a checklist for compliance with guidelines, and as a mechanism of surveillance. The baseline incidence rate of IV infiltrates, determined by the voluntary reporting system, was 5 per 1000 line days. Following initiation of the guidelines and checklist, the IV infiltrate rate increased to 9 per 1000 line days. In most months, the detection of IV infiltrates was improved by use of the checklist. During the post-intervention period the rate of Stage 4 infiltrates, as measured by usage of nitroglycerin ointment, was significantly reduced. In conclusion, the detection of IV infiltrates was improved following our quality improvement interventions. Further, use of an evidence-based guideline for managing infiltrates may reduce the most severe infiltrate injuries. PMID:26734388

    Cultured neonatal cardiomyocytes have long been used to study myofibrillogenesis and myofibrillar functions. Cultured cardiomyocytes allow for easy investigation and manipulation of biochemical pathways, and their effect on the biomechanical properties of spontaneously beating cardiomyocytes. The following 2-day protocol describes the isolation and culture of neonatal mouse cardiomyocytes. We show how to easily dissect hearts from neonates, dissociate the cardiac tissue and enrich cardiomyocytes from the cardiac cell-population. We discuss the usage of different enzyme mixes for cell-dissociation, and their effects on cell-viability. The isolated cardiomyocytes can be subsequently used for a variety of morphological, electrophysiological, biochemical, cell-biological or biomechanical assays. We optimized the protocol for robustness and reproducibility, by using only commercially available solutions and enzyme mixes that show little lot-to-lot variability. We also address common problems associated with the isolation and culture of cardiomyocytes, and offer a variety of options for the optimization of isolation and culture conditions. PMID:24056408

    The management of neonatal hyperbilirubinemia is very standardized. However, there is a lack of an objective method to evaluate the cerebral effects of bilirubin apart from brainstem auditory evoked potentials. There were few studies evaluating the effects of hyperbilirubinemia or phototherapy on the visual pathway in infants with hyperbilirubinemia. Serial visual evoked potentials of two groups of term neonates (N = 24)--group 1 with moderate hyperbilirubinemia (n = 16) and group 2 with severe hyperbilirubinemia (n = 8)--were evaluated prospectively. All infants had regular physical, neurologic, visual, and auditory evaluations until 3 years. Four (16%) had abnormal visual evoked potentials before 1 year, and the abnormalities returned to normal thereafter. There was no significant difference in visual evoked potentials between the two groups. All had normal neurodevelopmental status by 3 years, with the exception of one child from the severe group with ABO incompatibility with transient mild motor delay, hypotonia, and abnormal visual evoked potential. There were no abnormal effects of phototherapy on visual evoked potentials in infants with neonatal hyperbilirubinemia after 1 year of age. Although our sample size was small, the results suggest that the effects of hyperbilirubinemia on visual evoked potentials might be transient. (J Child Neurol 2006;21:58-62).

    We describe 2 cases of autoimmune lymphoproliferative syndrome (ALPS), which is a rare disorder of auto-immunity, chronic persistent or recurrent lymphadenopathy, splenomegaly, hepatomegaly and hyper gamma globulinemia (1gG, 1gA). Both cases presented in neonatal period which is a rare age of presentation in this disease. A 20 days old female neonate presented with respiratory symptoms which rapidly progressed needing ventilatory support. There was hepatomegaly and no auscultatory findings in the chest. Serial CBCs (complete blood counts) showed persistent leucocytosis with predominant lymphocytosis. Her chest X-ray showed left sided consolidation which responded poorly to antibiotics. Her prompt clinical response to steroids raised the suspicion of autoimmunity and the diagnosis was established after a negative bone marrow examination for leukemia and a positive result for ALPS on flow cytometry. The second case presented with anemia, thrombocytopenia starting in neonatal period followed by persistent lymphadenopathy, hepatosplenomegaly and recurrent infections which responded poorly to antibiotics. Diagnosis was delayed due to low index of suspicion, and finally achieved with multiple radiological studies, histopathology and flow cytometry.

    Dilation and abnormal tortuosity of retinal vessels are the hallmarks of severe retinopathy of prematurity (ROP) in premature infants. The stages of ROP are defined by vessel appearance at the interface between the vascular and avascular retinal areas. Deregulated signaling pathways involving hypoxia-inducible factors such as vascular endothelial growth factor (VEGF) are involved in the pathogenesis of ROP. VEGF-antagonists are increasingly being used as 'off-label medication' to treat this condition, with some success. We present Baby SM (female), who was born prematurely at 24 weeks gestation in a tertiary neonatal intensive care unit, and with a birth weight of 640 g. On screening at 35 weeks postmenstrual age (PMA), she was noted to have ROP, which became severe by 37 weeks PMA. She received one dose of intravitreal VEGF antagonist (Bevacizumab), resulting in a decrease in vessel tortuosity and dilation. However, repeat imaging at 4 weeks showed a re-emergence of vessel tortuosity. We believe the observed changes demonstrate an inherent retinal microvascular plasticity in premature neonates. With improved survival of extremely premature neonates and the availability of retinal imaging technology, we are now able to observe this plasticity.

    Abstract OBJECTIVE To review best practices for early recognition and treatment of conditions resulting in neonatal cholestasis, in order to improve long-term outcomes for affected infants. QUALITY OF EVIDENCE Studies, review articles, and meta-analyses pertaining to neonatal-onset cholestasis were sought via electronic databases. Reference lists of studies and review articles supplemented the electronic search. Studies were included if they examined the importance of early diagnosis and intervention for cholestatic jaundice of any cause, and mainly comprised Level II and Level III evidence. MAIN MESSAGE Review of the relevant literature supports the recommendation that infants with jaundice at 2 weeks of age should be tested for cholestasis by quantifying the direct reacting bilirubin levels in their blood. Subsequent rapid investigation using a diagnostic algorithm enables early diagnosis of the specific cause and facilitates timely intervention for conditions whose outcomes are improved by early treatment. CONCLUSION Universal screening for neonatal cholestasis might help with early identification of cases and improve outcomes, although further study is required in the North American setting.

    In the high-risk neonate, the direct determination of the red cell volume by radionuclide dilution technique appears to be the singularly definitive method of defining treatment efficacy, and is thus a useful evaluation and management tool for the pediatrician. For effective patient management, the red blood cell(RBC) volume of 69 preterm and term neonates was determined. The method utilized, Tc-99m-labeled RBCs, provided a fast and accurate answer with a large reduction in the absorbed radiation dose. In the population studied within a high-risk newborn ICU, the mean RBC volumes between the preterm and term neonates were without significant difference. Grouping and analysis of the RBC volume data with respect to birth weight, gestational ages, and 1- and 5-minute Apgar scores revealed on statistical difference. The mean value found in our population, 32.2 +/- 9.2 ml/kg, however, does differ from those previously reported in which the determinations were made using an indirect estimation from the plasma compartment.

    The newborn with seizures should be treated urgently, because of the high risk of consequent brain damage. In addition to general management in order to correct metabolic and functional unbalancement, associated with the fits, specific causes of neonatal seizures (hypoglicemia, hypocalcemia, hypomagnesiemia, hypo-hypernatremia, pyridoxine deficiency) should be immediately removed. If neonatal seizures depend on other non specific causes (anoxia, cerebral hemorrhagy, malformation, infection or other, a symptomatic anticonvulsant treatment should be carried out without delay. Useful drugs for the newborn are phenobarbital, phenytoin and benzodiazepine e.v. or e.m. After fits have been controlled, an oral maintenance therapy has to be started with phenobarbital or phenytoin in order to avoid seizure-relaps. Clinical EEG and hematological data should be monitored to detect side effects, as well as plasma drugs levels to achieve adequate maintenance doses. Criteria for discontinuing the neonatal seizures treatment have not been well established. On the bases of the data collected through a longitudinal study of 54 newborns who developed seizures in the first day of life, clinical and EEG criteria for discontinuing anticonvulsant therapy are discussed. If the fits are rare, short, immediately controlled and EEG is mildly abnormal, we attempt to discontinuing treatment within 15 days. If fits are unfrequent, varying in length, their therapeutical control is reached within 3 days and the EEG is markedly abnormal but recovered within 1 month, treatment is discontinuing between 15 days and 3 months.(ABSTRACT TRUNCATED AT 250 WORDS)

    Neonatal seizures are a potentially life-threatening pediatric problem with a variety of causes, such as birth trauma, asphyxia, congenital anomalies, metabolic disturbances, infections, and drug withdrawal or intoxication. Thorough and timely evaluations of such patients are necessary to identify and treat the underlying etiology, therefore reducing potential morbidity and mortality. We review neonatal seizures and hypocalcemia and present the case of a 6-day-old male infant who presented to a tertiary pediatric emergency department with seizure-like episodes. He was found to have markedly low serum calcium, magnesium, and parathyroid hormone concentrations, as well as a significantly elevated serum phosphate concentration. The etiology of these abnormalities was found to be maternal ingestion of extremely high doses of calcium carbonate during the third trimester of her pregnancy, an occurrence that has been reported only once in the literature. Education pertaining to the dangers of excessive calcium carbonate intake during pregnancy may be an important piece of anticipatory guidance for pregnant mothers with symptoms of gastroesophageal reflux, and questioning the mother of a neonate presenting with seizures about such over-the-counter medications may help to elucidate the diagnosis.

    HELLP syndrome is most often diagnosed between 27 and 37 weeks gestation. It is also a diagnosis that can be seen during the postpartum period. The effects of HELLP syndrome on the neonate can be significant. Recognizing the risks to the neonate can assist the clinician in preparing for the neonate prior to delivery. In doing so, the mortality and morbidity rates can be reduced.

  18. Neonatal Group B Streptococcal Disease in Otherwise Healthy Infants: Failure of Specific Neonatal Immune Responses

    PubMed Central

    Borghesi, Alessandro; Stronati, Mauro; Fellay, Jacques

    2017-01-01

    Only a small proportion of newborn infants exposed to a pathogenic microorganism develop overt infection. Susceptibility to infection in preterm infants and infants with known comorbidities has a likely multifactorial origin and can be often attributed to the concurrence of iatrogenic factors, environmental determinants, underlying pathogenic processes, and probably genetic predisposition. Conversely, infection occurring in otherwise healthy full-term newborn infants is unexplained in most cases. Microbial virulence factors and the unique characteristics of the neonatal immune system only partially account for the interindividual variability in the neonatal immune responses to pathogens. We here suggest that neonatal infection occurring in otherwise healthy infants is caused by a failure of the specific protective immunity to the microorganism. To explain infection in term and preterm infants, we propose an extension of the previously proposed model of the genetic architecture of infectious diseases in humans. We then focus on group B streptococcus (GBS) disease, the best characterized neonatal infection, and outline the potential molecular mechanisms underlying the selective failure of the immune responses against GBS. In light of the recent discoveries of pathogen-specific primary immunodeficiencies and of the role of anticytokine autoantibodies in increasing susceptibility to specific infections, we hypothesize that GBS disease occurring in otherwise healthy infants could reflect an immunodeficiency caused either by rare genetic defects in the infant or by transmitted maternal neutralizing antibodies. These hypotheses are consistent with available epidemiological data, with clinical and epidemiological observations, and with the state of the art of neonatal physiology and disease. Studies should now be designed to comprehensively search for genetic or immunological factors involved in susceptibility to severe neonatal infections. PMID:28326082

    The lifespan risk of seizures is highest in the neonatal period. Currently used therapies have limited efficacy. Although the treatment of neonatal seizures has not significantly changed in the last several decades, there has been substantial progress in understanding developmental mechanisms that influence seizure generation and responsiveness to anticonvulsants. Here we provide an overview of current approaches to the diagnosis and treatment of neonatal seizures, identifying some of the recent insights about the pathophysiology of neonatal seizures that may provide the foundation for better treatment.

    Sepsis is a major cause of neonatal morbidity and mortality, especially in vulnerable preterm populations. Immature immune defenses, and environmental and maternal factors contribute to this risk, with as many as a third of very preterm infants experiencing sepsis during their stay in the neonatal intensive care unit (NICU). Epidemiologic and twin studies have suggested that there is a genetic contribution to sepsis predilection. Several investigators have conducted candidate gene association studies on variants of specific interest and potential functional significance in neonatal sepsis. In this review, we describe details of studies that have evaluated genetic susceptibility in neonatal sepsis, and summarize findings from a review of candidate gene association studies.

    Alterations in neural networks are associated with the cognitive difficulties of the prematurely born. Using functional magnetic resonance imaging, we analyzed functional connectivity for preterm (PT) and term neonates at term equivalent age. Specifically, we constructed whole-brain networks and examined rich club (RC) organization, a common construct among complex systems where important (or "rich") nodes connect preferentially to other important nodes. Both PT and term neonates showed RC organization with PT neonates exhibiting significantly reduced connections between these RC nodes. Additionally, PT neonates showed evidence of weaker functional segregation. Our results suggest that PT birth is associated with fundamental changes of functional organization in the developing brain.

    Neonates are vulnerable to adverse drug reactions but reports of these events are relatively infrequent. Reporting can be increased by adapting a number of standard techniques to the unique features of neonatal care and pathology. However, clinicians and parents will be reluctant to report information about harms in the absence of mechanisms to ensure that reports affect clinical practice. Improved reporting will depend on education and cultural change that are informed by research about pharmacovigilance in neonatal settings. The efficient use of neonatal adverse drug reaction reports will require harmonization of terminology and interoperable databases.

    Despite advances in critical care medicine, neonatal sepsis remains a major cause of morbidity and mortality worldwide, with the greatest risk affecting very low birth weight, preterm neonates. The presentation of neonatal sepsis varies markedly from its presentation in adults, and there is no clear consensus definition of neonatal sepsis. Previous work has demonstrated that when neonates become septic, death can occur rapidly over a matter of hours or days and is generally associated with inflammation, organ injury, and respiratory failure. Studies of the transcriptomic response by neonates to infection and sepsis have led to unique insights into the early proinflammatory and host protective responses to sepsis. Paradoxically, this early inflammatory response in neonates, although lethal, is clearly less robust relative to children and adults. Similarly, the expression of genes involved in host protective immunity, particularly neutrophil function, is also markedly deficient. As a result, neonates have both a diminished inflammatory and protective immune response to infection which may explain their increased risk to infection, and their reduced ability to clear infections. Such studies imply that novel approaches unique to the neonate will be required for the development of both diagnostics and therapeutics in this high at-risk population. PMID:28224121

    Due to the introduction of the conjugate vaccine against serotype b, neonatal sepsis caused by Haemophilus influenzae became very rare. There is little data in Belgium concerning the prevalence of H. influenzae early onset neonatal sepsis and articles about neonatal sepsis and H. influenzae published in the last decade are scarce. We report two invasive infections with a non-typeable H. influenzae. These cases show that neonatal sepsis caused by non-typeable H. influenzae may be underestimated and we believe that there is need for a better registration of this kind of infection.

    Neonatal pain management has evolved dramatically in the past few decades. Evidence is clear that neonates experience pain. Furthermore, we are increasingly aware of the detrimental effects of untreated neonatal pain during a critical period of neuronal maturation. Providing safe and effective pain relief is a primary goal of neonatal critical care specialists to ensure good outcomes. However, there are lingering concerns regarding the harmful effects of sedative-analgesics on the developing brain. Thus, striking a fine balance between effective analgesia and avoiding serious short- and long-term adverse effects from pain medications remains a major challenge for caregivers.

    Background The use of transcutaneous bilirubin (TcB) as a screening tool, based on relevant population-specific nomogram, or proxy for total serum bilirubin (TSB) levels in assessing the risk of subsequent hyperbilirubinemia is supported by several clinical guidelines on the management of neonatal hyperbilirubinemia. However, while TcB has been found to significantly over-estimate TSB in neonates of African-American ancestry, with variations across TcB devices, no nomogram has been specifically reported for this racial group. This study therefore set out to develop TcB nomograms for healthy late pre-term and term black African neonates derived from two widely used bilirubinometers. Methods A retrospective analysis of 12,377 TcB measurements obtained from 6,373 neonates in the first postnatal week, over a period of 48 months using Bilichek and JM-103 bilirubinometers. TcB percentiles were computed from hour-specific TcB values and nomograms developed for each of the screening devices. Predictive ability of the 75th and 95th percentiles to detect significant hyperbilirubinemia was evaluated between 24–96 hours of age. The 95th percentile curve was compared with those from other populations. Results The velocity of TcB rise at 75th and 95th percentiles was generally higher with JM-103 than Bilichek. Both percentiles also peaked at higher TcB levels with JM-103. The 95th percentile for both instruments showed a downward trend as from approximately 114 hours. Both instruments had high negative predictive values across the selected time-epochs and lower discriminatory ability than reported in non-black populations. Conclusions The predictive utility of TcB as a potential screening tool varies across devices in black African neonates with or without risk of significant hyperbilirubinemia, and lower than levels reported in non-black populations. Equipment-specific nomograms should be considered for TcB monitoring in this racial population where TSB is not routinely

    For almost 25 years, the Neonatal Resuscitation Program of the American Academy of Pediatrics has provided educational tools that are used in the United States and throughout the world to teach neonatal resuscitation. Over that time period, the guidelines for resuscitation have been increasingly evidence-based and a formal system has been established to determine which steps should be updated on the basis of available information. The most recent update occurred in 2010. This article describes the evidence review process and the specific evidence that lead to a number of significant changes in practice that were included in the 2010 guidelines.

    Glucocorticoids are widely used to treat chronic lung disease in premature infants but their longer-term adverse effects on the cardiovascular system raise concerns. We reported that neonatal dexamethasone treatment in rats induced in the short term molecular indices of cardiac oxidative stress and cardiovascular tissue remodelling at weaning, and that neonatal combined antioxidant and dexamethasone treatment was protective at this time. In this study, we investigated whether such effects of neonatal dexamethasone have adverse consequences for NO bioavailability and cardiovascular function at adulthood, and whether neonatal combined antioxidant and dexamethasone treatment is protective in the adult. Newborn rat pups received daily i.p. injections of a human-relevant tapering dose of dexamethasone (D; n= 8; 0.5, 0.3, 0.1 μg g−1) or D with vitamins C and E (DCE; n= 8; 200 and 100 mg kg−1, respectively) on postnatal days 1–3 (P1–3); vitamins were continued from P4 to P6. Controls received equal volumes of vehicle from P1 to P6 (C; n= 8). A fourth group received vitamins alone (CCE; n= 8). At P100, plasma NO metabolites (NOx) was measured and isolated hearts were assessed under both Working and Langendorff preparations. Relative to controls, neonatal dexamethasone therapy increased mortality by 18% (P < 0.05). Surviving D pups at adulthood had lower plasma NOx concentrations (10.6 ± 0.8 vs. 28.0 ± 1.5 μm), an increased relative left ventricular (LV) mass (70 ± 2 vs. 63 ± 1%), enhanced LV end-diastolic pressure (14 ± 2 vs. 8 ± 1 mmHg) and these hearts failed to adapt output with increased preload (Δcardiac output: 2.9 ± 2.0 vs. 10.6 ± 1.2 ml min−1) or afterload (Δcardiac output: −5.3 ± 2.0 vs.1.4 ± 1.2 ml min−1); all P < 0.05. Combined neonatal dexamethasone with antioxidant vitamins improved postnatal survival, restored plasma NOx and protected against cardiac dysfunction at adulthood. In conclusion, neonatal dexamethasone therapy promotes

    Background In 1988, WHO estimated around 787,000 newborns deaths due to neonatal tetanus. Despite few success stories majority of the Low and Middle Income Countries (LMICs) are still struggling to reduce neonatal mortality due to neonatal tetanus. We conducted a systematic review to understand the interventions that have had a substantial effect on reducing neonatal mortality rate due to neonatal tetanus in LMICs and come up with feasible recommendations for decreasing neonatal tetanus in the Pakistani setting. Methods We systemically reviewed the published literature (Pubmed and Pubget databases) to identify appropriate interventions for reducing tetanus related neonatal mortality. A total of 26 out of 30 studies were shortlisted for preliminary screening after removing overlapping information. Key words used were “neonatal tetanus, neonatal mortality, tetanus toxoid women”. Of these twenty-six studies, 20 were excluded. The pre-defined exclusion criteria was (i) strategies and interventions to reduce mortality among neonates not described (ii) no abstract/author (4 studies) (iii) not freely accessible online (1 study) (iv) conducted in high income countries (2 studies) and (v) not directly related to neonatal tetanus mortality and tetanus toxoid immunization (5). Finally six studies which met the eligibility criteria were entered in the pre-designed data extraction form and five were selected for commentary as they were directly linked with neonatal tetanus reduction. Results Interventions that were identified to reduce neonatal mortality in LMICs were: a) vaccination of women of child bearing age (married and unmarried both) with tetanus toxoid b) community based interventions i.e. tetanus toxoid immunization for all mothers; clean and skilled care at delivery; newborn resuscitation; exclusive breastfeeding; umbilical cord care and management of infections in newborns c) supplementary immunization (in addition to regular EPI program) d) safer delivery

    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 with ScT and ET (ET group). All neonates with septic shock admitted to our NICU from 2005 to 2015 were included in the study. Overall, 101/9030 (1.1%) neonates had septic shock. Fifty neonates out of 101 (49.5%) received one or more ETs. The mortality rate was 36% in the ET group and 51% in the ScT group (p = 0.16). At multivariate logistic regression analysis, controlling for potentially confounding factors significantly associated with death (gestational age, serum lactate, inotropic drugs, oligoanuria), ET showed a marked protective effect (Odds Ratio 0.21, 95% Confidence Interval: 0.06–0.71; p = 0.01). The lack of observed adverse events should encourage the use of this procedure in the treatment of neonates with septic shock. PMID:27171076

    Ondansetron is the drug of choice to prevent nausea in women undergoing cesarean surgery and can be used to prevent neonatal abstinence syndrome (NAS). The pharmacokinetics of ondansetron have not been characterized in pregnant women or in newborns. A nonlinear mixed-effects modeling approach was used to analyze plasma samples obtained from 20 nonpregnant and 40 pregnant women following a single administration of 4 or 8 mg ondansetron, from umbilical cord blood at delivery, and from neonates after birth. The analysis indicates that: ondansetron disposition is not affected by pregnancy (P > 0.05), but influenced by dose (P < 0.05), and is characterized by rapid transplacental transfer and longer elimination half-life in neonates compared to their mother. A dosing regimen for prevention of NAS was designed based on the model. The regimen involves IV administration of 4 mg to the mothers shortly before cord clamping, or oral administration of 0.07 mg/kg (or equivalently 0.04 mg/kg IV) to neonates.

Methods For 65 countries with high-quality vital registration, we used each country’s observed early and late neonatal proportional cause distributions. For the remaining 129 countries, we used multinomial logistic models to estimate these distributions. For countries with low child mortality we used vital registration data as inputs and for countries with high child mortality we used neonatal cause-of-death distribution data from studies in similar settings. We applied cause-specific proportions to neonatal death estimates from the United Nations Inter-agency Group for Child Mortality Estimation, by country and year, to estimate cause-specific risks and numbers of deaths. Findings Over time, neonatal deaths decreased for most causes. Of the 2.8 million neonatal deaths in 2013, 0.99 million deaths (uncertainty range: 0.70–1.31) were estimated to be caused by preterm birth complications, 0.64 million (uncertainty range: 0.46–0.84) by intrapartum complications and 0.43 million (uncertainty range: 0.22–0.66) by sepsis and other severe infections. Preterm birth (40.8%) and intrapartum complications (27.0%) accounted for most early neonatal deaths while infections caused nearly half of late neonatal deaths. Preterm birth complications were the leading cause of death in all regions of the world. Conclusion The neonatal cause-of-death distribution differs between the early and late periods and varies with neonatal mortality rate level. To reduce neonatal deaths, effective interventions to address these causes must be incorporated into policy decisions. PMID:25558104

    Early neonatal death (ENND), defined as the death of a newborn between zero and seven days after birth, represents 73% of all postnatal deaths worldwide. Despite a 50% reduction in childhood mortality, reduction of ENND has significantly lagged behind other Millennium Developmental Goal achievements and is a growing contributor to overall mortality in children aged <5 years. The etiology of ENND is closely related to the level of a country's industrialization. Hence, prematurity and congenital anomalies are the leading causes in high-income countries. Furthermore, sudden unexpected early neonatal deaths (SUEND) and collapse have only recently been identified as relevant and often preventable causes of death. Concomitantly, perinatal-related events such as asphyxia and infections are extremely relevant in Africa, South East Asia, and Latin America and, together with prematurity, are the principal contributors to ENND. In high-income countries, according to current research evidence, survival may be improved by applying antenatal and perinatal therapies and immediate newborn resuscitation, as well as by centralizing at-risk deliveries to centers with appropriate expertise available around the clock. In addition, resources should be allocated to the close surveillance of newborn infants, especially during the first hours of life. Many of the conditions leading to ENND in low-income countries are preventable with relatively easy and cost-effective interventions such as contraception, vaccination of pregnant women, hygienic delivery at a hospital, training health care workers in resuscitation practices, simplified algorithms that allow for early detection of perinatal infections, and early initiation of breastfeeding and skin-to-skin care. The future is promising. As initiatives undertaken in previous decades have led to substantial reduction in childhood mortality, it is expected that new initiatives targeting the perinatal/neonatal periods are bound to reduce ENND and

    The lactocrine hypothesis suggests a mechanism whereby milk-borne bioactive factors delivered to nursing offspring affect development of neonatal tissues. The objective of this study was to assess whether nursing affects testicular development in neonatal boars as reflected by: (1) Sertoli cell number and proliferation measured by GATA-4 expression and proliferating cell nuclear antigen immunostaining patterns; (2) Leydig cell development and steroidogenic activity as reflected by insulin-like factor 3 (INSL3), and P450 side chain cleavage (scc) enzyme expression; and (3) expression of estrogen receptor-alpha (ESR1), vascular endothelial growth factor (VEGF) A, and relaxin family peptide receptor (RXFP) 1. At birth, boars were randomly assigned (n = 6-7/group) to nurse ad libitum or to be pan fed porcine milk replacer for 48 h. Testes were collected from boars at birth, before nursing and from nursed and replacer-fed boars at 50 h on postnatal day (PND) 2. Sertoli cell proliferating cell nuclear antigen labeling index increased (P < 0.01) from birth to PND 2 in nursed, but not in replacer-fed boars. Sertoli cell number and testicular GATA-4 protein levels increased (P < 0.01) from PND 0 to PND 2 only in nursed boars. Neither age nor nursing affected testicular INSL3, P450scc, ESR1, or VEGFA levels. However, testicular relaxin family peptide receptor 1 (RXFP1) levels increased (P < 0.01) with age and were greater in replacer-fed boars on PND 2. Results suggest that nursing supports neonatal porcine testicular development and provide additional evidence for the importance of lactocrine signaling in pigs.

    Globally, newborn health is now considered as high-level national priority. The current neonatal and infant mortality rate in India is 29 per 1000 live births and 42 per 1000 live births, respectively. The last decade has seen a tremendous growth of neonatal intensive care in India. The proliferation of neonatal intensive care units, as also the infusion of newer technologies with availability of well-trained medical and nursing manpower, has led to good survival and intact outcomes. There is good care available for neonates whose parents can afford the high-end healthcare, but unfortunately, there is a deep divide and the poor rural population is still underserved with lack of even basic newborn care in few areas! There is increasing disparity where the 'well to do' and the 'increasingly affordable middle class' is able to get the most advanced care for their sick neonates. The underserved urban poor and those in rural areas still contribute to the overall high neonatal morbidity and mortality in India. The recent government initiative, the India Newborn Action Plan, is the step in the right direction to bridge this gap. A strong public-private partnership and prioritisation is needed to achieve this goal. This review highlights the current situation of neonatal intensive care in India with a suggested plan for the way forward to achieve better neonatal care.

    Neonatal sepsis is the third leading cause of neonatal mortality and a major public health problem, especially in developing countries. Although recent medical advances have improved neonatal care, many challenges remain in the diagnosis and management of neonatal infections. The diagnosis of neonatal sepsis is complicated by the frequent presence of noninfectious conditions that resemble sepsis, especially in preterm infants, and by the absence of optimal diagnostic tests. Since neonatal sepsis is a high-risk disease, especially in preterm infants, clinicians are compelled to empirically administer antibiotics to infants with risk factors and/or signs of suspected sepsis. Unfortunately, both broad-spectrum antibiotics and prolonged treatment with empirical antibiotics are associated with adverse outcomes and increase antimicrobial resistance rates. Given the high incidence and mortality of sepsis in preterm infants and its long-term consequences on growth and development, efforts to reduce the rates of infection in this vulnerable population are one of the most important interventions in neonatal care. In this review, we discuss the most common questions and challenges in the diagnosis and management of neonatal sepsis, with a focus on developing countries. PMID:25604489

    Background: The neurobiology of neonatal pain processing, especially in preterm infants, differs significantly from older infants, children, adolescence, and adults. Research suggests that strong painful procedures or repeated mild procedures may permanently modify individual pain processing. Acute injuries at critical developmental periods are risk factors for persistent altered neurodevelopment. The purpose of this narrative review is to present the seminal and current literature describing the unique physiological aspects of neonatal pain processing. Methods: Articles describing the structures and physiological processes that influence neonatal pain were identified from electronic databases Medline, PubMed, and CINAHL. Results: The representation of neonatal pain physiology is described in three processes: Local peripheral nervous system processes, referred to as transduction; spinal cord processing, referred to as transmission and modulation; and supraspinal processing and integration or perception of pain. The consequences of undermanaged pain in preterm infants and neonates are discussed. Conclusion: Although the process and pain responses in neonates bear some similarity to processes and pain responses in older infants, children, adolescence, and adults; there are some pain processes and responses that are unique to neonates rendering them at risk for inadequate pain treatment. Moreover, exposure to repeated painful stimuli contributes to adverse long-term physiologic and behavioral sequelae. With the emergence of studies showing that painful experiences are capable of rewiring the adult brain, it is imperative that we treat neonatal pain effectively. PMID:25506507

    Background Determining the safety and pharmacokinetics of antifungal agents in neonates is important. A previous single-dose pharmacokinetic study of micafungin in neonates demonstrated that doses of 0.75 to 3 mg/kg produced lower plasma micafungin concentrations than in older patients because of increased apparent plasma clearance of micafungin in neonates. The primary objective of this study was to assess the safety and pharmacokinetics of an increased (15 mg/kg/day) dose of micafungin. Methods A repeated dose, open-label pharmacokinetic and safety trial of intravenous micafungin in 12 preterm neonates > 48 hours of life with suspected systemic infections. Neonates received 15 mg/kg/day of micafungin for 5 days. Blood samples were drawn relative to either the fourth or fifth dose. Systemic exposure was assessed by examination of the plasma area under the curve. Results The median birth weight and gestational age of the neonates were 775 g and 27 weeks, respectively. No adverse events related to micafungin were detected. The mean area under the curve and clearance for the cohort was 437.5 μg · h/mL and 0.575 mL/min/kg, respectively. The calculated clearance and volume of distribution for neonates was greater than that observed in older children and adults. Conclusions These data suggest that 15 mg/kg dosing in premature neonates corresponds to an exposure of approximately 5 mg/kg in adults. No adverse events related to micafungin were observed.

    Health care systems today are complex, technically proficient, competitive, and market-driven. One outcome of this environment is the recent phenomenon in the health care field of "consumerism." Strong emphasis is placed on customer service, with organized efforts to understand, measure, and meet the needs of customers served. The purpose of this article is to describe the current understanding and measurement of parent needs and expectations with neonatal intensive care services from the time the expectant parents enter the health care system for the birth through the discharge process and follow-up care. Through literature review, 11 dimensions of care were identified as important to parents whose infants received neonatal intensive care: assurance, caring, communication, consistent information, education, environment, follow-up care, pain management, participation, proximity, and support. Five parent satisfaction questionnaires-the Parent Feedback Questionnaire, Neonatal Index of Parent Satisfaction, Inpatient Parent Satisfaction-Children's Hospital Minneapolis, Picker Institute-Inpatient Neonatal Intensive Care Unit Survey, and the Neonatal Intensive Care Unit-Parent Satisfaction Form-are critically reviewed for their ability to measure parent satisfaction within the framework of the neonatal care delivery process. An immense gap was found in our understanding about what matters most and when to parents going through the neonatal intensive care experience. Additional research is required to develop comprehensive parent satisfaction surveys that measure parent perceptions of neonatal care within the framework of the care delivery process.

    2017-01-01

    Neonatal and adult neutrophils are distinctly different from one another due to well-defined and documented deficiencies in neonatal cells, including impaired functions, reduced concentrations of microbicidal proteins and enzymes necessary for pathogen destruction, and variances in cell surface receptors. Neutrophil maturation is clearly demonstrated throughout pregnancy from the earliest hematopoietic precursors in the yolk sac to the well-developed myeloid progenitor cells in the bone marrow around the seventh month of gestation. Notable deficiencies of neonatal neutrophils are generally correlated with gestational age and clinical condition, so that the least functional neutrophils are found in the youngest, sickest neonates. Interruption of normal gestation secondary to preterm birth exposes these shortcomings and places the neonate at an exceptionally high rate of infection and sepsis-related mortality. Because the fetus develops in a sterile environment, neonatal adaptive immune responses are deficient from lack of antigen exposure in utero. Newborns must therefore rely on innate immunity to protect against early infection. Neutrophils are a vital component of innate immunity since they are the first cells to respond to and defend against bacterial, viral, and fungal infections. However, notable phenotypic and functional disparities exist between neonatal and adult cells. Below is review of neutrophil ontogeny, as well as a discussion regarding known differences between preterm and term neonatal and adult neutrophils with respect to cell membrane receptors and functions. Our analysis will also explain how these variations decrease with postnatal age. PMID:28293548

    Background Intrauterine exposure to antidepressants may lead to neonatal symptoms from the central nervous system, respiratory system and gastrointestinal system. Finnegan score (Neonatal Abstinence Score, NAS) has routinely been used to assess infants exposed to antidepressants in utero. Aim The purpose was to study neonatal maladaptation syndrome in infants exposed to selective serotonin reuptake inhibitors (SSRI) or serotonin-norepinephrine reuptake inhibitors (SNRI) in utero. Method Retrospective cohort study of women using antidepressants during pregnancy and their infants. Patients were identified from the electronic health record system at Karolinska University Hospital Huddinge containing pre-, peri- and postnatal information. Information was collected on maternal and infant health, social factors and pregnancy. NAS sheets were scrutinized. Results 220 women with reported 3rd trimester exposure to SSRIs or SNRIs and who gave birth between January 2007 and June 2009 were included. Seventy seven women (35%) used citalopram, 76 used (35%) sertraline, 34 (15%) fluoxetine and 33 (15%) other SSRI/SNRI. Twenty-nine infants (13%) were admitted to the neonatal ward, 19 were born prematurely. NAS was analyzed in 205 patients. Severe abstinence was defined as eight points or higher on at least two occasions (on a scale with maximum 40 points), mild abstinence as 4 points or higher on at least two occasions. Seven infants expressed signs of severe abstinence and 46 (22%) had mild abstinence symptoms. Hypoglycemia (plasma glucose <2.6 mmol/L) was found in 42 infants (19%). Conclusion Severe abstinence in infants prenatally exposed to antidepressants was found to be rare (3%) in this study population, a slightly lower prevalence than reported in previous studies. Neonatal hypoglycemia in infants prenatally exposed to antidepressant may however be more common than previously described. PMID:25365553

    We planned and implemented an evidence-based program to screen for jaundice and to try to increase the proportion of women breastfeeding for 6 months. The program involved home visitation by a registered nurse to provide education on and support of breastfeeding, and to perform physical assessment of both mothers and newborns, including screening for neonatal jaundice. Quantitative data showed increased breastfeeding rates at 6 months. In addition, readmission rates for jaundice were higher when compared to regional benchmarks. However, the average length of stay for treatment of jaundice was shorter than regional benchmarks. Qualitative data indicated that the program was effective at achieving its goals and was valued by participants.

The authors report on the case of a male neonate with a massive DAVM who presented at birth with macrocephaly and high-output cardiac failure. The child initially underwent treatment with surgical clipping of the large main feeding artery. Hydrocephalus, thought to be due to venous hypertension, developed when the boy was 8 months old. The condition resolved after interventional embolization treatment. The patient did not require placement of a ventriculoperitoneal shunt. At 21 months of age, the child had near normal development without any focal neurological deficits.

    The article reviews the intestinal ischemia theme on newborn and children. The intestinal ischemia may be either acute - intestinal infarction (by vascular obstruction or by reduced mesenteric blood flow besides the occlusive mechanism), either chronic. In neonates, acute intestinal ischemia may be caused by aortic thrombosis, volvulus or hypoplastic left heart syndrome. In children, acute intestinal ischemia may be caused by fibromuscular dysplasia, volvulus, abdominal compartment syndrome, Burkitt lymphoma, dermatomyositis (by vascular obstruction) or familial dysautonomia, Addison's disease, situs inversus abdominus (intraoperative), burns, chemotherapy administration (by nonocclusive mesenteric ischemia). Chronic intestinal ischemia is a rare condition in pediatrics and can be seen in abdominal aortic coarctation or hypoplasia, idiopathic infantile arterial calcinosis.

    Summary Anaesthetic-induced developmental neurotoxicity (AIDN) has been clearly established in laboratory animal models. The possibility of neurotoxicity during uneventful anaesthetic procedures in human neonates or infants has led to serious questions about the safety of paediatric anaesthesia. However, the applicability of animal data to clinical anaesthesia practice remains uncertain. The spectre of cerebral injury due to cerebral hypoperfusion, metabolic derangements, coexisting disease, and surgery itself further muddles the picture. Given the potential magnitude of the public health importance of this issue, the clinician should be cognisant of the literature and ongoing investigations on AIDN, and raise awareness of the risks of both surgery and anaesthesia.

    Summary Both iron deficiency and iron excess during the fetal and neonatal period bode poorly for developing organ systems. Maternal conditions such as iron deficiency, diabetes mellitus, hypertension and smoking, and preterm birth are the common causes of perinatal iron deficiency. Long-term neurodevelopmental impairments and predisposition to future iron deficiency that are prevalent in infants with perinatal iron deficiency require early diagnosis, optimal treatment and adequate follow-up of infants at risk for the condition. However, due to the potential for oxidant-mediated tissue injury, iron overload should be avoided in the perinatal period, especially in preterm infants. PMID:17157088

    There has been a worldwide increase in bed bug infestations over the last 10-15 years. A major stigma is placed upon the institutions found to be infested. We report our experience with an outbreak of the tropical bed bug, Cimex hemipterus, in a neonatal unit. The outbreak not only affected the admitted newborns and mothers by causing a wide variety of rashes and inducing sleeplessness, but also impinged upon the health professionals and their families by producing similar symptomology. It is important for healthcare providers to be aware of, and for each healthcare facility to have, bed bug prevention and control policies.

    1981-12-01

    Eight newborn infants with opaque right lungs were examined. Clinically, the main problem associated with the opaque right lung is mild respiratory distress, and radiographyically, the findings consist of (a) a totally opaque right lung, (b) a semiopaque right lung, or (c) an opaque right upper lobe only. These findings are usually interpreted as representing pneumonia, empyema, or hydrochlothorax, but the fact that they clear within 24 to 48 hours indicates that none of these diseases is the cause. It is thought that neonatal opaque right lung results from the transient retention of normal fetal fluid in the right lung.

    Deafness must be recognized in infancy in order to reduce auditory disability to a minimum. To achieve this, it is important to implement screening programmes as soon after birth as possible. In the United States, the Joint Committee on Infant Hearing recommended in 1982 that identification of hearing loss should be screened in the neonatal period. This early detection is now considered critical for optimal rehabilitative outcome. This paper presents the "state of art" neonatal screening principles and procedures. In France, neonatal screening programs for auditory dysfunction are not consistent with these principles. Evoked otoacoustic emissions represent an important advance in screening for hearing loss in normal neonates and babies from neonatal intensive care units. This method records very low intensity sound energy released by the cochlea in response to a brief sound stimulation. These otoacoustic emissions show promise as a rapid, cost-effective means of quickly discharging all babies with normal peripherical auditory systems.

    Neonates, especially those born prematurely, are at high risk of morbidity and mortality from sepsis. Multiple factors, including prematurity, invasive life-saving medical interventions, and immaturity of the innate immune system, put these infants at greater risk of developing infection. Although advanced neonatal care enables us to save even the most preterm neonates, the very interventions sustaining those who are hospitalized concurrently expose them to serious infections due to common nosocomial pathogens, particularly coagulase-negative staphylococci bacteria (CoNS). Moreover, the health burden from infection in these infants remains unacceptably high despite continuing efforts. In this paper, we review the epidemiology, immunological risk factors, diagnosis, prevention, treatment, and outcomes of neonatal infection due to the predominant neonatal pathogen CoNS.

    The innate and adaptive immune responses in neonates are usually functionally impaired when compared with their adult counterparts. The qualitative and quantitative differences in the neonatal immune response put them at risk for the development of bacterial and viral infections, resulting in increased mortality. Newborns often exhibit decreased production of Th1-polarizing cytokines and are biased toward Th2-type responses. Studies aimed at understanding the plasticity of the immune response in the neonatal and early infant periods or that seek to improve neonatal innate immune function with adjuvants or special formulations are crucial for preventing the infectious disease burden in this susceptible group. Considerable studies focused on identifying potential immunomodulatory therapies have been performed in murine models. This article highlights the strategies used in the emerging field of immunomodulation in bacterial and viral pathogens, focusing on preclinical studies carried out in animal models with particular emphasis on neonatal-specific immune deficits.

    Introduction Preeclampsia (preE) is pregnancy-induced hypertension affecting a significant proportion of pregnant women worldwide and can cause detrimental effects in the mother and newborn. Some of the effects in the newborn include neonatal thrombocytopenia. Pertaining specifically to neonatal thrombocytopenia, several questions remain unanswered. Discussion According to the current literature, neonatal thrombocytopenia due to maternal preE is highly prevalent in the general population and the incidence is reported to be around 30% worldwide. This review gives an insight into the syndrome and summarizes the possible pathological mechanisms, the diagnostic approach, complications, and therapeutic interventions of neonatal thrombocytopenia. It also identifies the involvement of other cell lines, apart from platelets in the newborns. Furthermore, we suggest a future prospective study to investigate the pathogenesis of preE and plan a study involving animal models to come up with a possible therapeutic intervention to prevent preE and its various consequences in neonates.

    Acute kidney injury (AKI) is an under-recognized morbidity of neonates; the incidence remains unclear due to the absence of a unified definition of AKI in this population and because previous studies have varied greatly in screening for AKI with serum creatinine and urine output assessments. Premature infants may be born with less than half of the nephrons compared with term neonates, predisposing them to chronic kidney disease (CKD) early on in life and as they age. AKI can also lead to CKD, and premature infants with AKI may be at very high risk for long-term kidney problems. AKI in neonates is often multifactorial and may result from prenatal, perinatal, or postnatal insults as well as any combination thereof. This review focuses on the causes of AKI, the importance of early detection, the management of AKI in neonates, and long-term sequela of AKI in neonates.

    Many primary immunodeficiencies (PIDs) manifest in the neonatal period but can be challenging to diagnose and manage optimally. In part, the difficulty stems from the natural immaturity of the neonatal immune system that may mask immune deficits and/or complicate interpretation of clinical findings and laboratory assays. The great diversity of PIDs--from innate immune system defects to those that impact the humoral and/or cellular components of the adaptive immune system--and the rapid rate at which new PIDs are being discovered makes it challenging for practitioners to stay current. Moreover, recent appreciation for immune deficiencies that lead to autoinflammation and autoimmunity have broadened the spectrum of neonatal PID, adding additional complexity to an already intricate field. This article serves to highlight the deficiencies in the neonatal immune system, while providing a review of the more common PIDs that present in the neonate and guidelines for diagnosis and supportive care.

    2005-01-01

    The genital mycoplasmas represent a complex and unique group of microorganisms that have been associated with a wide array of infectious diseases in adults and infants. The lack of conclusive knowledge regarding the pathogenic potential of Mycoplasma and Ureaplasma spp. in many conditions is due to a general unfamiliarity of physicians and microbiology laboratories with their fastidious growth requirements, leading to difficulty in their detection; their high prevalence in healthy persons; the poor design of research studies attempting to base association with disease on the mere presence of the organisms in the lower urogenital tract; the failure to consider multifactorial aspects of diseases; and considering these genital mycoplasmas only as a last resort. The situation is now changing because of a greater appreciation of the genital mycoplasmas as perinatal pathogens and improvements in laboratory detection, particularly with regard to the development of powerful molecular nucleic acid amplification tests. This review summarizes the epidemiology of genital mycoplasmas as causes of neonatal infections and premature birth; evidence linking ureaplasmas with bronchopulmonary dysplasia; recent changes in the taxonomy of the genus Ureaplasma; the neonatal host response to mycoplasma and ureaplasma infections; advances in laboratory detection, including molecular methods; and therapeutic considerations for treatment of systemic diseases.

    Research on neonatal cognition has developed very recently in comparison with the long history of research on child behavior. The last sixty years of research have provided a great amount of evidence for infants’ numerous cognitive abilities. However, only little of this research concerns newborn infants. What do we know about neonatal cognition? Using a variety of paradigms, researchers became able to probe for what newborns know. Amongst these results, we can distinguish several levels of cognitive abilities. First, at the perceptual or sensory level, newborns are able to process information coming from the social world and the physical objects through all their senses. They are able to discriminate between object shapes and between faces; that is, they are able to detect invariants, remember and recognize them. Second, newborns are able to abstract information, to compare different inputs and to match them across different sensory modalities. We will argue that these two levels can be considered high-level cognitive abilities: they constitute the foundations of human cognition. Furthermore, while some perceptual competencies can stem from the fetal period, many of these perceptual and cognitive abilities cannot be a consequence of the environment surrounding the newborn before birth.

    Acute otitis externa (AOE) is an infection of the external auditory canal, the auricle, and the outer surface of the tympanic membrane. Although AOE is one of the most common otologic conditions encountered in pediatric population, it is known to primarily affect children older than 2 years. We report a case of AOE caused by Staphylococcus aureus in a 23-day-old neonate. A 23-day-old female infant presented to our neonatology clinic with irritability and discharge from the right ear. There were yellow otorrhea, mild erythema, and edema of right external ear canal. There was no sign of otitis media on otoscopy. The results of laboratory tests were insignificant. The discharge culture grew colonies of methicillin-sensitive Staphylococcus aureus. After 48 hours of treatment with intravenous cloxacillin, significant improvement was observed. The present case highlights an unusual presentation of staphylococcal infection in a neonate. This is the first case of methicillin-sensitive Staphylococcus aureus otitis externa in an immunocompetent newborn. PMID:27703821

    PubMed Central

    2015-01-01

    The maturation of the central nervous system’s (CNS’s) sensory connectivity is driven by modality-specific sensory input in early life. For the somatosensory system, this input is the physical, tactile interaction with the environment. Nociceptive circuitry is functioning at the time of birth; however, there is still considerable organization and refinement of this circuitry that occurs postnatally, before full discrimination of tactile and noxious input is possible. This fine-tuning involves separation of tactile and nociceptive afferent input to the spinal cord’s dorsal horn and the maturation of local and descending inhibitory circuitry. Disruption of that input in early postnatal life (for example, by tissue injury or other noxious stimulus), can have a profound influence on subsequent development, and consequently the mature functioning of pain systems. In this review, the impact of neonatal surgical incision on nociceptive circuitry is discussed in terms of the underlying developmental neurobiology. The changes are complex, occurring at multiple anatomical sites within the CNS, and including both neuronal and glial cell populations. The altered sensory input from neonatal injury selectively modulates neuronal excitability within the spinal cord, disrupts inhibitory control, and primes the immune system, all of which contribute to the adverse long-term consequences of early pain exposure.

    Exposure to carbon dioxide (CO2) is the most prevalent method used to euthanize rodents in biomedical research. The purpose of this study was to determine the time of CO2 exposure required to euthanize neonatal mice (0 to 10 days old). Multiple groups of mice were exposed to 100% CO 2 for time periods between 5 and 60 min. Mice were placed in room air for 10 or 20 min after CO2 exposure, to allow for the chance of recovery. If mice recovered at one time point, a longer exposure was examined. Inbred and outbred mice were compared. Results of the study indicated that time to death varied with the age of the animals and could be as long as 50 min on the day of birth and differed between inbred and outbred mice. Institutions euthanizing neonatal mice with CO2 may wish to adjust their CO 2 exposure time periods according the age of the mice and their genetic background.

    We report a case of a female neonate whose pulse oximetry screening for congenital heart disease at 40 h of life was positive. The pregnancy was uneventful with no relevant family history. The neonate presented with bluish discolouration of the skin lasting until day 15. Cardiovascular examination and chest radiography were normal. Septic screening was negative. Oxygen therapy was started with poor response; investigations revealed a methaemoglobinaemia of 7.4%. The methaemoglobin level reached a peak of 15% on day 10, falling thereafter. The infant was discharged by day 20 with a normal physical examination and a methaemoglobinaemia of 11.4%. By 2 months of age this had fallen to 2.4%. Further investigation revealed a haemoglobin M variant: a heterozygous mutation of the γ globin gene known as Hb F-M Viseu. The mutation occurs in the γ chain, therefore the methaemoglobinaemia is transitory, resolving with the transition from fetal to adult haemoglobin. PMID:25754164

    Thrombocytopenia occurs frequently in newborn infants with sepsis, but the exact mechanism remains obscure in those infants who do not have evidence of disseminated intravascular coagulation. Since recent work has suggested a possible immune mechanism for thrombocytopenia observed in adults with sepsis, we have investigated the role of platelet-associated immunoglobulin in severe neonatal infections. To detect PAIgG we use a method employing protein A and peroxidase-antiperoxidase as a labeled antibody. PAIgG was quantitated by phase contrast microscopy and expressed as a reactive index. Our control group included 16 normal newborn infants whose mean RI was 0.65 +/- 0.01 SE. In addition to the control group, five infants with nonimmune thrombocytopenia were included; their mean RI was 0.66 +/- 0.01 SE. Seventeen newborn infants with severe infections were assayed for PAIgG. Eight of nine infants with bacterial infections had increased RI, with a mean of 1.16 +/- 0.03 SE (P less than 0.01). Six of the eight infants with viral infections had elevated RI, with a mean of 1.23 +/- 0.03 SE (P less than 0.01). These findings suggest that an immune mechanism may be involved in the thrombocytopenia of severe neonatal infection.

    In a large percentage of the infants who die in the neonatal intensive care setting, an end-of-life decision was made before death, usually a decision to forego life-sustaining treatment. This was confirmed in a recent study in The Netherlands that showed also that a minority of cases include the administration of drugs to hasten death, usually in patients with severe congenital multiple or central nervous system anomalies. Over 80% of Dutch pediatricians support this option under certain conditions. Almost all pediatricians are of the opinion that these cases have to be subject to public review, but they favor review by a committee of independent medical, judicial, and ethical professionals rather than by the public prosecutor. A discussion group on this subject recently made a proposal for such a reviewing procedure to the Dutch governmental authorities and described the requirements concerning end-of-life decisions in neonatal medicine. Proper handling of ethical aspects of medical treatment including review and feedback after end-of-life decisions can contribute to high standards of quality of care.

    Neurobehavioural development of 35 infants of drug dependent mothers was compared with the development of 37 reference infants as part of a prospective longitudinal research project. Infants of drug dependent mothers had more poor responses than the other children on neurological examination. This difference is significant only when data of infants of drug dependent mothers born at full term are analysed. Two tailed testing indicated that significantly more infants of drug dependent mothers than reference children had electro-encephalograms rated as suspect or abnormal. By the end of the first month the infants of drug dependent mothers tended to be more active, and they had worse scores than the reference children on the neonatal behavioural assessment scale. Analysing data only of infants born at full term, the groups differ significantly on the interactive items. The results of this study show that even after treatment for the neonatal abstinence syndrome, infants of drug dependent mothers seem to differ from comparison children, which could indicate later developmental problems.

    Neonatal jaundice can be best understood as a balance between the production and elimination of bilirubin, with a multitude of factors and conditions affecting each of these processes. When an imbalance results because of an increase in circulating bilirubin (or the bilirubin load) to significantly high levels (severe hyperbilirubinemia), it may cause permanent neurologic sequelae (kernicterus). In most infants, an increase in bilirubin production (e.g., due to hemolysis) is the primary cause of severe hyperbilirubinemia, and thus reducing bilirubin production is a rational approach for its management. The situation can become critical in infants with an associated impaired bilirubin elimination mechanism as a result of a genetic deficiency and/or polymorphism. Combining information about bilirubin production and genetic information about bilirubin elimination with the tracking of bilirubin levels means that a relative assessment of jaundice risk might be feasible. Information on the level of bilirubin production and its rate of elimination may help to guide the clinical management of neonatal jaundice.

    Objective: To study the incidence and outcome of systemic infections with methicillin sensitive (MSSA) and methicillin resistant Staphylococcus aureus (MRSA) infections in Australasian neonatal nurseries. Methods: Prospective longitudinal study of systemic infections (clinical sepsis plus positive cultures of blood and/or cerebrospinal fluid) in 17 Australasian neonatal nurseries. Results: The incidence of early onset sepsis with S aureus, mainly MSSA, was 19 cases per 244 718 live births or 0.08 per 1000. From 1992 to 1994, MRSA infections caused only 8% of staphylococcal infections. From 1995 to 1998, there was an outbreak of MRSA infection, in two Melbourne hospitals. The outbreak resolved, after the use of topical mupirocin and improved handwashing. Babies with MRSA sepsis were significantly smaller than babies with MSSA sepsis (mean birth weight 1093 v 1617 g) and more preterm (mean gestation 27.5 v 30.3 weeks). The mortality of MRSA sepsis was 24.6% compared with 9.9% for MSSA infections. The mortality of early onset MSSA sepsis, however, was 39% (seven of 18) compared with 7.3% of late onset MSSA infection presenting more than two days after birth. Conclusions: S aureus is a rare but important cause of early onset sepsis. Late onset MRSA infections carried a higher mortality than late onset MSSA infections, but babies with early onset MSSA sepsis had a particularly high mortality. PMID:15210669

    2012-01-01

    Neonatal follow-up program (NFP) is becoming the corner stone of standard, high quality care provided to newborns at risk of future neuorodevelopmental delay. Most of the recognized neonatal intensive care units in the developed countries are adopting NFP as part of their mandatory care for the best long term outcome of high risk infants, especially very low birth weight (VLBW) infants. Unfortunately, in the developing and in underdeveloped countries, such early detection and intervention programs are rarely existing, mainly because of the lack of awareness of and exposure to such programs in spite of the increasing numbers of surviving sick newborns due to advancement in neonatal care in these countries. This is a review article to explore the Neonatal follow-up programs looking at historical development, benefts and aims, and standard requirements for successful program development that can be adopted in our countries. In conclusion, proper Neonatal follow-up programs are needed to improve neonatal outcome. Therefore all professionals working in the feld of neonatal care in developing countries should cooperate to create such programs for early detection and hence early intervention for any adverse long term outcome in high-risk newborn infants PMID:27493326

    Individually, metabolic disorders are rare, but overall they account for a significant number of neonatal disorders affecting the central nervous system. The neonatal clinical manifestations of inborn errors of metabolism (IEMs) are characterized by nonspecific systemic symptoms that may mimic more common acute neonatal disorders like sepsis, severe heart insufficiency, or neonatal hypoxic-ischemic encephalopathy. Certain IEMs presenting in the neonatal period may also be complicated by sepsis and cardiomyopathy. Early diagnosis is mandatory to prevent death and permanent long-term neurological impairments. Although neuroimaging findings are rarely specific, they play a key role in suggesting the correct diagnosis, limiting the differential diagnosis, and may consequently allow early initiation of targeted metabolic and genetic laboratory investigations and treatment. Neuroimaging may be especially helpful to distinguish metabolic disorders from other more common causes of neonatal encephalopathy, as a newborn may present with an IEM prior to the availability of the newborn screening results. It is therefore important that neonatologists, pediatric neurologists, and pediatric neuroradiologists are familiar with the neuroimaging findings of metabolic disorders presenting in the neonatal time period.

    This work aimed to evaluate immune events in HIV-1-exposed uninfected neonates born from mothers who control (G1) or not (G2) the plasma viral load, using unexposed neonates as controls. Cord blood from each neonate was collected, plasma and mononuclear cells were separated and the lymphoproliferation and cytokine pattern were evaluated. The results demonstrated that the in vitro lymphoproliferation induced by polyclonal activators was higher in the G2 neonates. Nevertheless, no cell culture responded to poll synthetic HIV-1 envelope peptides. The cytokine dosage in the plasma and supernatants of polyclonally-activated cultures demonstrated that, while IL-4 and IL-10 were the dominant cytokines produced in G1 and control groups, IFN-gamma and TNF-alpha were significantly higher in G2 neonates. Systemic levels of IL-10 observed among the G1 neonates were higher in those born from anti-retroviral treated mothers. In summary, our results indicate an altered immune responsiveness in neonates exposed in utero to HIV and support the role of maternal anti-retroviral treatment to attenuate it.

    In the study of early brain development, tissue segmentation of neonatal brain MR images remains challenging because of the insufficient image quality due to the properties of developing tissues. Among various brain tissue segmentation algorithms, atlas-based brain image segmentation can potentially achieve good segmentation results on neonatal brain images. However, their performances rely on both the quality of the atlas and the spatial correspondence between the atlas and the to-be-segmented image. Moreover, it is difficult to build a population atlas for neonates due to the requirement of a large set of tissue-segmented neonatal brain images. To combat these obstacles, we present a longitudinal neonatal brain image segmentation framework by taking advantage of the longitudinal data acquired at late time-point to build a subject-specific tissue probabilistic atlas. Specifically, tissue segmentation of the neonatal brain is formulated as two iterative steps of bias correction and probabilistic-atlas-based tissue segmentation, along with the longitudinal atlas reconstructed by the late time image of the same subject. The proposed method has been evaluated qualitatively through visual inspection and quantitatively by comparing with manual delineations and two population-atlas-based segmentation methods. Experimental results show that the utilization of a subject-specific probabilistic atlas can substantially improve tissue segmentation of neonatal brain images.

    Objective The aim of this article is to examine characteristics of birth tourism (BT) neonates admitted to a neonatal intensive care unit (NICU). Methods This was a retrospective review over 3 years; BT cases were identified, and relevant perinatal, medical, social, and financial data were collected and compared with 100 randomly selected non-birth tourism neonates. Results A total of 46 BT neonates were identified. They were more likely to be born to older women (34 vs. 29 years; p < 0.001), via cesarean delivery (72 vs. 48%; p = 0.007), and at a referral facility (80 vs. 32%; p < 0.001). BT group had longer hospital stay (15 vs. 7 days; p = 0.02), more surgical intervention (50 vs. 21%; p < 0.001), and higher hospital charges (median $287,501 vs. $103,105; p = 0.003). One-third of BT neonates were enrolled in public health insurance program and four BT neonates (10%) were placed for adoption. Conclusion Families of BT neonates admitted to the NICU face significant challenges. Larger studies are needed to better define impacts on families, health care system, and society.

    On the rare occasion when neonatal goiter is the cause of airway compromise, it typically presents with a palpable neck mass. In the setting of maternal Graves' disease (GD), fetal and neonatal goiters are most commonly caused by maternal treatment with antithyroid medication, and the goiter resolves within days of initiation of thyroxine replacement in the neonate. We describe an atypical presentation of a patient with severe neonatal GD born to a euthyroid mother at 35 weeks' gestational age with respiratory compromise, symptoms of hyperthyroidism, and a nonpalpable thyroid gland. The mother had a history of GD treated with radioactive iodine ablation; during the pregnancy she was treated with levothyroxine throughout and propylthiouracil beginning at 5 months' gestation, for fetal tachycardia. Laboratory testing after birth confirmed neonatal GD. The patient was treated with methimazole, Lugol's solution, and levothyroxine, and the patient remained euthyroid from day of life 10. After multiple extubation attempts failed, the patient was found on visualization studies to have a large, predominantly posterior, "vise-like" goiter encasing the larynx and upper trachea. The patient was successfully extubated, and all medications were discontinued on day of life 60. The patient remained euthyroid 1 month after discontinuation of treatment. The patient's atypical presentation illustrates the need for early neck imaging in patients with neonatal GD and respiratory distress, especially when the thyroid gland is not palpable. Treatment options for resolving a goiter due to neonatal GD are not clear.

    Globally, health care providers worldwide recognize that severe neonatal jaundice is a "silent" cause of significant neonatal morbidity and mortality. Untreated neonatal jaundice can lead to death in the neonatal period and to kernicterus, a major cause of neurologic disability (choreo-athetoid cerebral palsy, deafness, language difficulty) in children who survive this largely preventable neonatal tragedy. Appropriate technologies are urgently needed. These include tools to promote and enhance visual assessment of the degree of jaundice, such as simpler transcutaneous bilirubin measurements and readily available serum bilirubin measurements that could be incorporated into routine treatment and follow-up. Widespread screening for glucose-6-phoshate dehydrogenase deficiency is needed because this is often a major cause of neonatal jaundice and kernicterus worldwide. Recognition and treatment of Rh hemolytic disease, another known preventable cause of kernicterus, is critical. In addition, effective phototherapy is crucial if we are to make kernicterus a "never-event." Finally it is essential that we conduct appropriate population-based studies to accurately elucidate the magnitude of the problem. However, knowledge alone is not sufficient. If we are to implement these and other programs and technologies to relegate severe neonatal jaundice and its sequelae to the history books, screening and interventions must be low cost and technologically appropriate for low and middle income nations.

  16. Understanding neonatal jaundice: UK practice and international profile.

    Over the last 25 years there have been considerable advances in the treatment and technologies used in the care of newborn infants. Most of these advances are related to the care of the premature infants and there have been few changes in the management of conditions commonly seen in term infants. Neonatal jaundice is one of the commonest neonatal disorders and has been recognized since early history. Early neonatal jaundice is usually caused by the physiological destruction of red blood cells in the infant and its importance lies in the ability of the bilirubin pigment so produced to cross the blood brain barrier resulting in neurotoxicity. Prolonged neonatal jaundice (after 14 days of age) may be an indication of an underlying liver disorder. The approach to neonatal jaundice has remained largely unchanged over the last two to three decades. We continue to rely on visual inspection to assess the severity of early neonatal jaundice. We have technology that is effective in reducing the level of bilirubinaemia but in the UK there is no clear consensus as to the level at which jaundice should be treated. We do not have a standardized approach to the management of prolonged jaundice and there is potential for infants with significant liver problems to be diagnosed at a relatively late stage. Some countries (for example the US) have professional bodies who have introduced guidelines to ensure a standardized approach to the jaundice infant. We have little information about neonatal jaundice treatment in other parts of the developing world.

    Conducting clinical trials in neonates is challenging, and knowledge gaps in neonatal clinical pharmacology exist. We surveyed the US Food and Drug Administration databases and identified 43 drugs studied in neonates or referring to neonates between 1998 and 2014. Twenty drugs were approved in neonates. For 10 drugs, approval was based on efficacy data in neonates, supplemented by pharmacokinetic data for four drugs. Approval for neonates was based on full extrapolation from older patients for six drugs, and partial extrapolation was the basis of approval for four drugs. Dosing recommendations differed from older patients for most drugs, and used body-size based adjustment in neonates. Trial failures were associated with various factors including inappropriate dose selection. Successful drug development in neonates could be facilitated by an improved understanding of the natural history and pathophysiology of neonatal diseases and identification and validation of clinically relevant biomarkers.

    Background: Globally, the proportion of child deaths that occur in the neonatal period remains a high level of 37–41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China. Methods: All the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed. Results: A total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents’ concern about the long-term outcomes was the main reason of medical care withdrawal. Conclusions: Neonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to

The child presented with a phenotype of neonatal Marfan syndrome, revealed by acute and refractory heart failure, finally leading to death within the first 4 months of life. Her mother had a common clinical presentation. Genetic analysis revealed an inherited FBN1 mutation. This intronic mutation (c.6163+3_6163+6del), undescribed to date, leads to exon 49 skipping, corresponding to in-frame deletion of 42 amino acids (p.Ile2014_Asp2055del). FBN1 next-generation sequencing did not show any argument for mosaicism. Association in the same family of severe neonatal and classical Marfan syndrome illustrates the intrafamilial phenotype variability.

    The increased reach of health programs in India during the past few decades has contributed to a decline in postnatal mortality including infant and child mortality; however, reduction in neonatal mortality remained negligible. About seven out of ten neonatal deaths take place within a week after birth. The progress in reduction as well as dimension along which early neonatal mortality is patterned in India remains unclear. We examine the trend in early neonatal mortality and its possible demographic and socioeconomic predictors using nationally representative data. Data from the three cross-sectional rounds of the National Family Health Survey of India from 1992 to 1993, 1998 to 1999 and 2005 to 2006 were analyzed. Early neonatal mortality rate was estimated for selected demographic and socioeconomic population groups and for major states in India using information on births and deaths during the 3 years preceding the respective surveys. Using the multivariate logistic regression model, we assessed proximate determinants of early neonatal deaths during 1990-2006. Sex of the child, child's birth size, birth order and interval, type of child's birth, mother's age at child's birth, mother's educational status, religion, household economic status and region of residence emerged as significant predictors of early neonatal deaths. The adjusted multivariate analysis indicates that majority of the socio-demographic predictors reveal a negligible decline in the probability of early neonatal deaths during 1990-2006. Moreover, based on comprehensive reviews of scientific literature on newborn's survival we document some of the recommended ways to prevent early neonatal mortality in India.

  2. Hospitalised neonates in Estonia commonly receive potentially harmful excipients

    PubMed Central

    2012-01-01

    Background Information on the neonatal exposure to excipients is limited. Our aim was to describe the extent of excipient intake by Estonian neonates; to classify the excipients according to potential neonatal toxicity and thereby to measure the extent of exposure of neonates to potentially harmful excipients. Methods A prospective cohort study that recorded all medicines prescribed to patients aged below 28 days admitted to Tartu University Hospital from 01.02-01.08 2008 and to Tallinn Children’s Hospital from 01.02- 01.08 2009 was conducted. Excipients were identified from Summaries of Product Characteristics and classified according to toxicity following a literature review. Results 1961 prescriptions comprising 107 medicines were written for 348/490 neonates admitted. A total of 123 excipients were found in 1620 (83%) prescriptions and 93 (87%) medicines. 47 (38%) of these excipients were classified as potentially or known to be harmful to neonates. Most neonates (97%) received at least one medicine (median number 2) with potentially or known to be harmful excipient. Parabens were the most commonly used known to be harmful excipients and sodium metabisulphite the most commonly used potentially harmful excipient, received by 343 (99%) and 297 (85%) of treated neonates, respectively. Conclusions Hospitalised neonates in Estonia are commonly receiving a wide range of excipients with their medication. Quantitative information about excipients should be made available to pharmacists and neonatologists helping them to take into account excipient issues when selecting medicines and to monitor for adverse effects if administration of medicines containing excipients is unavoidable.

    2016-01-01

    Objective: The objective of this study was to describe the medication errors in hospitalized patients, comparing those in neonates with medication errors across the age spectrum. Method: In tier 1, PubMed, Embase and Google Scholar were searched, using selected MeSH terms relating to hospitalized paediatric, adult and elderly populations. Tier 2 involved a search of the same electronic databases for literature relating to hospitalized neonatal patients. Results: A total of 58 articles were reviewed. Medication errors were well documented in each patient group. Overall, prescribing and administration errors were most commonly identified across each population, and mostly related to errors in dosing. Errors due to patient misidentification and overdosing were particularly prevalent in neonates, with 47% of administration errors involving at least tenfold overdoses. Unique errors were identified in elderly patients, comprising duplication of therapy and unnecessary prescribing of medicines. Overall, the medicines most frequently identified with error across each patient group included: heparin, antibiotics, insulin, morphine and parenteral nutrition. While neonatal patients experience the same types of medication errors as other hospitalized patients, the medication-use process within this group is more complex and has greater consequences resulting from error. Suggested strategies to help overcome medication error most commonly involved the integration of a clinical pharmacist into the treating team. Conclusion: This review highlights that each step of the medication-use process is prone to error across the age spectrum. Further research is required to develop targeted strategies relevant to specific patient groups that integrate key pharmacy services into wards. PMID:27298721

    Isolated ACTH deficiency (IAD) is a rare cause of neonatal cholestasis and hypoglycaemia. This diagnosis has a 20% mortality potential if unrecognised. We describe a case of an infant presenting with cholestatic jaundice and hypoglycaemia. The patient had laboratory findings suggestive of IAD, which was later confirmed with molecular genetic testing. One of the mutations this patient had is a new finding. The patient was started on glucocorticoid replacement therapy after which his bilirubin and glucose levels normalised. PMID:27535729

    2015-12-07

    As neonatal sepsis is a severe condition, there is a call for reliable biomarkers to differentiate between infected and noninfected newborns. Although blood culture has been considered as the gold standard, this analysis is still too slow and limited by false negative results. Use of CRP is hampered by a physiological 3-day increase, resulting in a low sensitivity to detect sepsis at an early stage. A moderate diagnostic accuracy of other acute phase proteins has been demonstrated (serum amyloid A, procalcitonin, lipopolysaccharide binding protein, mannose binding lectin and hepcidin). In neonatal sepsis, changed chemokine/cytokine levels are observed before those of acute phase reactants. High IL-6, IL-8, IL-10 and TNF-α concentrations are detected in infected infants. Soluble interleukin-2 receptor has been used to identify bacteremia, whereas low plasma RANTES concentrations are characteristic for septicemia. Several cell adhesion molecules contribute to the pathogenesis of sepsis. As an upregulated CD64 expression on granulocytes is found within 1-6h after bacterial invasion, serial CD64 measurements could guide antibiotic therapy. An increased CD11b/CD18 density can improve the diagnosis, and a positive correlation between CD11b and the severity of systemic inflammation has been reported. An early increase in sCD14-ST presepsin is also observed during sepsis, whereas high sTREM-1 values in early-onset neonatal sepsis (EOS) have been associated with mortality. Biomarkers resulting from proteomics are also promising. A 4-biomarker 'mass restricted' score has been validated as diagnostic for intra-amniotic infection and/or inflammation. S100A8 in amniotic fluid is a strong predictor of an increased incidence of EOS. Proteomic analysis of cord blood has revealed altered protein expression patterns. The ApoSAA score is useful for identifying sepsis and could guide prescription of antibiotics. (1)H-NMR and GC-MS metabolomics allow to diagnose septic shock, which is

    Aim: Neonatal sepsis is an important cause of mortality and morbidity in newborns. The causative agents may be different in different units and may change in time. It was aimed to examine the microbiological agents leading to sepsis, clinical features and antibiotic resistances in babies with sepsis hospitalized in our unit in a two-year period. Material and Methods: The clinical features, microbiological and laboratory results, antibiotic resistance patterns and mortality rates of the newborns with sepsis followed up in our unit between 2010 and 2011 were examined in the patient record system. Results: 351 babies diagnosed with sepsis among 3219 patients hospitalized in the neonatal intensive care unit were included in the study. The mean gestational age was found to be 30.1±4.1 weeks, the mean birth weight was found to be 1417.4±759.1 g and the mean hospitalization time was found to be 43.6±34.4 days. Blood cultures were found to be positive in 167 (47.6%) patients, urine cultures were found to be positive in 6 (7.1%) patients and cerebrospinal fluid cultures were found to be positive in 34 (9.6%) cases. Candida grew in 5 patients (2 patients with early-onset sepsis and 3 patients with late-onset sepsis). The most common cause of sepsis was found to be staphylococci (coagulase negative staphylococcus was found in 65 patients (51%) and Staphylococcus aureus was found in 38 patients (39%). 49.6% (n=63) of the gram positive bacteriae and 60% (n=21) of the gram negative bacteriae were resistant to antibiotics. Six (7.1%) of the patients who were infected with these bacteriae were lost. In total 24 babies were lost because of sepsis. The bacteriae which caused to mortality with the highest rate included E. coli, coagulase negative staphylocicci, S. aureus and Klebsiella. Low birth weight, mechanical ventilation and parenteral nutrition were found to be significant risk factors in terms of mortality. Conclusions: Staphylococci were found to be the most common agents

    Numerosity discrimination has been demonstrated in newborns, but not in fetuses. Fetal magnetoencephalography allows non-invasive investigation of neural responses in neonates and fetuses. During an oddball paradigm with auditory sequences differing in numerosity, evoked responses were recorded and mismatch responses were quantified as an indicator for auditory discrimination. Thirty pregnant women with healthy fetuses (last trimester) and 30 healthy term neonates participated. Fourteen adults were included as a control group. Based on measurements eligible for analysis, all adults, all neonates, and 74% of fetuses showed numerical mismatch responses. Numerosity discrimination appears to exist in the last trimester of pregnancy.

    Following neonatal ischaemic brain injury, irregular vessels increase in size owing to luxury perfusion. These may be demonstrated by conventional colour flow Doppler (CFD) imaging at the periphery of the infarcted area. We present a case in which power Doppler imaging (PDI) was performed in addition to CFD in a neonate with unexplained seizures and which proved more sensitive than CFD in demonstrating luxury perfusion. Ultrasound appearances were compared with those seen on cranial CT. PDI can be a useful adjunct to conventional CFD examination of the neonatal brain in cerebral infarction.

    Background and objective Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme deficiency in humans, affecting 400 million people worldwide and a high prevalence in persons of African, Middle Asian countries. The most common clinical manifestations are neonatal jaundice and acute hemolytic anemia, which is caused by the impairment of erythrocyte’s ability to remove harmful oxidative stress triggered by exogenous agents such as drugs, infection, or fava bean ingestion. Neonatal hyperbilirubinemia caused by G6PD is strongly associated with mortality and long-term neurodevelopmental impairment. The study aims to determine a level of G6PD in healthy neonates. Methods We obtained blood spot samples from 268 infants around 24-72 hours in their age who has unsuspected intranatal and neonatal disorders. Glucose 6 phosphate dehydrogenase “Perkin Elmer, Finland” level is determined by Victor 2D Fluorometer assay, developing of neonatal jaundice is examined by recall. Results The76.5% of all participants (n=205) was assessed 4.36±1.15 Ug/Hb in normal reference range of G6PD, other 23.5% (n=63) was 0.96±0.51 Ug/Hb with G6PD deficiency. In the both sex, 51.5% of male 0.88±0.46 Ug/Hb (n=33) and 47.6% of female (n=30) 0.97±0.55 Ug/Hb was assessed with G6PD deficiency. Developing Jaundice period in number of 63 neonates with G6PD deficiency, 86% of neonates (n=54) was in 1-4 days, 4% of neonates (n=3) was in 5-7 days and there is no sign of jaundice in 9% (n=6). Therefore neonates with G6PD deficiency, 53.9% (n=34) continued jaundice more than two weeks. Conclusions G6PD deficiency was determined in male neonates (51.5%) more than female (47.6%). The 76.5% of all participants (n=205) was assessed 4.36±1.15 Ug/Hb in normal reference range of G6PDH other 23.5% (n=63) of all participants was 0.96±0.51 Ug/Hb with G6PD deficiency. It shows that G6PD might be one potential risk of neonatal jaundice and hyperbilirubinemia in neonates in Mongolia.

    Simple low-cost, evidence-based interventions such as clean delivery practices, immediate warming, umbilical cord care, and neonatal resuscitation could prevent 40% to 70% of newborn deaths globally, but many obstacles preclude the provision of those basic interventions for all newborns, particularly in low-resource regions. Global efforts have led to widespread development of neonatal clinical practice guidelines, training programs, and policies. Because of a shortage of health care resources, standards of care have been redefined to meet the needs of underserved populations. This article provides an overview of the challenges, efforts, and controversies surrounding neonatal health in low-resource settings.

    The resuscitation principles of securing the airway and stabilizing hemodynamics remain the same in any neonatal emergency. However, stabilizing endocrine disorders may prove especially challenging. Several organ systems are affected simultaneously and the clinical presentation can be subtle. Although not all-inclusive, the implementation of newborn screening tests has significantly reduced morbidity and mortality in neonates. Implementing routine screening tests worldwide and improving the accuracy of present tests remains the challenge for healthcare providers. With further study of these disorders and best treatment practices we can provide neonates presenting to the emergency department with the best possible outcomes.

    Arachidonic acid (AA) metabolites have been implicated in neonatal pathologic states such as respiratory distress syndrome (RDS). Since free (nonprotein bound) AA is the substrate for synthesis of these compounds, a decreased capacity to bind AA in neonatal plasma could contribute to these disorders. AA binding was assayed by equilibrium dialysis in plasma samples from healthy adults and various infant groups. Plasma from these infant groups bound significantly less AA than adult plasma. Premature infants with RDS and premature infants receiving intralipid had the lowest capacity to bind AA. The increased availability of free AA may be important in neonatal pathophysiologic states involving arachidonate metabolites.

    Standardised parenteral nutrition formulations are routinely used in the neonatal intensive care units in Australia and New Zealand. In 2010, a multidisciplinary group was formed to achieve a consensus on the formulations acceptable to majority of the neonatal intensive care units. Literature review was undertaken for each nutrient and recommendations were developed in a series of meetings held between November 2010 and April 2011. Three standard and 2 optional amino acid/dextrose formulations and one lipid emulsion were agreed by majority participants in the consensus. This has a potential to standardise neonatal parenteral nutrition guidelines, reduce costs and prescription errors.

    Twenty preterm infants were randomly assigned to receive either a general-purpose intravenous amino acid solution or a neonatal formula at 1.5 gm/kg/day with 50 nonprotein energy calories for 1 week. Both groups demonstrated similar rates of weight gain and similar liver function test results, but comparison of changes from baseline amino acid values disclosed significant intergroup differences for levels of plasma glycine, taurine, valine, and methionine after 7 days of infusion. Comparison of plasma aminograms of study patients with those of normally growing, enterally fed preterm infants showed that infants who received the neonatal solution had similar amino acid profiles, with the exception of low plasma concentrations of tyrosine and elevated concentrations of threonine. The general-purpose solution, as compared with findings in historic enteral controls, produced low plasma valine, tyrosine, and taurine levels, and elevated levels of glycine and methionine. Advantages with the neonatal amino acid solution include reductions in plasma glycine and methionine levels, plus the provision of taurine. Providing tyrosine remains a problem.

    Background The highest incidence of meningitis occurs during the neonatal period and (then) infancy. Although Bacterial agents are the most dangerous cause of neonatal and childhood meningitis yet viruses especially, enteroviruses (EV), are by far the most common cause of meningitis in this age group. Objectives The aim of the current study was to evaluate the role of EVs in neonatal and childhood meningitis in the Mashhad city of Iran. Materials and Methods This was a descriptive study that was performed at Imam Reza hospital in a period of six months (March to September 2007), during which all of the cerebral spinal fluid (CSF) samples from the neonatal intensive care unit (NICU) and pediatrics ward were collected and real time-polymerase chain reaction (RT-PCR) for EVs was done on these samples. Clinical data were collected retrospectively from hospital files. Results We collected 58 CSF samples (35 neonates and 23 children) during six months. Pleocytosis of CSF was seen in 51.1% of the subjects (28% of neonates, and 66.6% of infants and children). Enteroviruses PCR was positive in 37.1% (13) of neonates and 34.7% (8) of children. Pleocytosis of CSF was seen in 23% and 75% of EV positive neonates and children, respectively. Polymorphonuclear (PMN) dominance (PMN > 50%) of CSF was seen in 50% and 33% of EV positive neonates and children, respectively. There were three cases of bacterial meningitis in our group; EV PCR result was positive for one of these subjects. Concomitant bacterial infection (meningitis and sepsis) was seen in 9.5% (two cases) of EV positive CSFs in our study. Almost half of the available neonates (four of nine) with pure enteroviral meningitis (EVM) were discharged (in good condition) with final diagnosis of culture negative sepsis (CNS) and mean length of hospital stay (MLOS) of 4.3 days. One (12.5%) of the neonates with EVM, who had a very low birth weight (< 1500 mg), was expired, and two (25%) cases were discharged with brain damage and

    Incontinentia pigmenti (IP) is a rare multisystem disease, X linked dominant disorder. As all X linked dominant diseases, it is usually male-lethal. Female newborn admitted to the neonatal intensive care unit on the first day of life was diagnosed as having probable herpetic infection with vesicular skin lesions distributed on upper right limb and inferior limbs. Family history showed that her 22-year-old mother had hypopigmented lesions on the lower limbs and her 13-month-old sister had hyperpigmented lesions on the trunk and limbs. In newborns, herpes infection emerges as the principal diagnosis of vesicular rash, due to the importance of precocious diagnosis and treatment. Other hypothesis must be considered in a newborn with vesicobullous rash, such as IP. PMID:22688469

    Over the last two decades, advances in laparoscopic surgery and minimally invasive techniques have transformed the operative management of neonatal colorectal surgery for conditions such as anorectal malformations (ARMs) and Hirschsprung’s disease. Evolution of surgical care has mainly occurred due to the use of laparoscopy, as opposed to a laparotomy, for intra-abdominal procedures and the development of trans-anal techniques. This review describes these advances and outlines the main minimally invasive techniques currently used for management of ARMs and Hirschsprung’s disease. There does still remain significant variation in the procedures used and this review aims to report the current literature comparing techniques with an emphasis on the short- and long-term clinical outcomes.

    Since the Institute of Medicine published Crossing the Quality Chasm in 2001, healthcare systems have become more focused on improving the quality of healthcare delivery. At Oregon Health & Science University and Doernbecher Children's Hospital, we recognize the need to take an interprofessional, team-based approach to improving the care we provide to our current and future patients. We describe here an ongoing quality improvement project in the Doernbecher Neonatal Intensive Care Unit (NICU), with specific attention to the factors we believe have contributed to the implementation and early success of the project. These factors include the history of quality improvement work in our NICU and in the field of neonatology, the "dyad leadership" structure under which we operate in our NICU, and our developing understanding of the concept of "team intelligence." These elements have led to the formation of a team that can practice shared decision making and work as one to realize a shared goal.

    Hydronephrosis secondary to an anomalous ureteropelvic junction was detected antenatally in more than 60 neonatal renal units Those 21 units that exhibited partial obstruction or dilatation without obstruction were selected for this study. They were assessed and followed by serial diuretic isotope renography (99mtechnetium-diethylenetriaminepentaacetic acid augmented with furosemide) and ultrasonography. Excretory urography was used selectively. Of the 17 renal units that could be assessed 88 per cent demonstrated labile ureteropelvic junctions. Indeed, in 3 to 6 months, when the definitive status seemed to be attained, 41 per cent (7 units) had deteriorated, 12 per cent (2 units) remained stable and 47 per cent (8 units) underwent spontaneous improvement. We recommend a 3 to 6-month observation period for patients with hydronephrosis secondary to ureteropelvic junction anomalies when definite obstruction cannot be confirmed by isotope renography.

    Congenital hypomagnesemia is a rare disease, with an impact on cognitive and neurological development. We report on three familial cases of congenital hypomagnesemia, two boys and one girl who belong to the same consanguineous family. They all presented neonatal seizures and a psychomotor developmental delay. Cerebral computed tomography showed cerebral atrophy and calcifications in one case and magnetic resonance imaging found predominant cerebellar atrophy in the two other cases. All three patients also had hypocalcemia, hyperphosphoremia, and hypomagnesemia. The parathyroid hormone blood level was low in two cases and normal in the third. One 7-month old patient died. The others received a supplementation of calcium and magnesium, which normalized calcemia, phosphatemia but not magnesemia, which remained low despite high doses. They have both developed cognitive and behavioral impairments.

    Gastric pneumatosis is extremely rare during infancy. It has been reported in association with necrotizing enterocolitis or congenital abnormalities such as pyloric stenosis. Here, we report a case of gastric pneumatosis in a premature neonate on synchronized nasal intermittent positive pressure ventilation. No pneumatosis was noted in the rest of the bowel or esophagus. There could have been mild damage in the gastric mucosa, either related to the placement of the feeding tube or secondary to the use of indomethacin or both. The condition was further aggravated by noninvasive ventilation. An increase in intragastric pressure resulted in the submucosal dissection of air followed by the development of gastric pneumatosis. Conservative management strategies, including the use of a nasogastric tube for decompression and the withholding of feeding, successfully managed the gastric pneumatosis in our patient. An uneventful recovery was made after conservative management. Prompt recognition and evaluation of this condition were essential for making the diagnosis. PMID:23705077

    Neonatal teeth is a rare disorder of tooth eruption, arising in the oral cavity, usually in the anterior mandible, in the first month of life. Its etiology is unknown. This condition can cause breastfeeding difficulties, besides aspiration or swallowing of the teeth. We describe the case of a premature infant in the second day of life presented with gingival edema, redness and discrete swelling in the region of the mandibular central incisors. Ten days later, two small teeth with hypermobility were detected. Extraction of those teeth was performed. With this clinical case we intend to show the rarity of this entity, especially in premature infants, the possible association with various syndromes and the need for a multifactorial approach to the treatment decision (extraction / conservative treatment).

    2017-01-01

    Development of lymphoid tissue is determined by interactions between stromal lymphoid tissue organiser (LTo) and hematopoietic lymphoid tissue inducer (LTi) cells. A failure for LTo to receive appropriate activating signals during embryogenesis through lymphotoxin engagement leads to a complete cessation of lymph node (LN) and Peyer’s patch development, identifying LTo as a key stromal population for lymphoid tissue organogenesis. However, little is known about the equivalent stromal cells that induce spleen development. Here, by dissociating neonatal murine spleen stromal tissue for re-aggregation and transplant into adult mouse recipients, we have identified a MAdCAM-1+CD31+CD201+ spleen stromal organizer cell-type critical for new tissue formation. This finding provides an insight into the regulation of post-natal spleen tissue organogenesis, and could be exploited in the development of spleen regenerative therapies. PMID:28067323

    Decisions about neonatal end-of-life care have been studied intensely over the last 20 years in The Netherlands. Nationwide surveys were done to quantify these decisions, provide details and monitor the effect of guidelines, new regulations and other interventions. One of those interventions was the Groningen Protocol for newborn euthanasia in severely ill newborns, published in 2005. Before publication, an estimated 20 cases of euthanasia per year were performed. After publication, only two cases in five years were reported. Studies suggested that this might be partly caused by the lack of consensus about the dividing line between euthanasia and palliative care. New recommendations about paralytic medication use in dying newborns were issued to increase transparency and to improve reporting of euthanasia. New surveys will be needed to measure the effects of these interventions. This cycle of interventions and measurements seems useful for continuous improvement of end-of-life care in newborns.

    The introductory summarises the classical path of heme degradation and classification of jaundice. Subsequently, a description of neonatal types of jaundice is given, known as Crigler Najjar, Gilberts, DubinJohnson and Rotor syndromes, emphasising the explanation of the molecular mechanisms of these metabolic disorders. Special attention is given to a recently discovered molecular mechanism of the Rotor syndrome. The mechanism is based on the inability of the liver to retrospectively uptake the conjugated bilirubin fraction primarily excreted into the blood, not bile. A reduced ability of the liver to uptake the conjugated bilirubin contributes to the development of hyperbilirubinemia in common disorders of the liver and bile ducts and to the toxicity of xenobiotics and drugs using transport proteins for conjugated bilirubin.

    Pregnant heroin-addicted women constitute a major social problem that should not be ignored. Newborns may develop a neonatal abstinence syndrome (NAS). They present with behavioural troubles running a typical clinical course. The level of severity of NAS will be accurately determined, leading to definition of the most appropriate therapy. The best therapeutic formula appears to be paregoric elixir, mixed with phenobarbital if necessary. Least severe cases can be easily controlled by appropriate surrounding conditions. Pharmacological as well as physiopathological effects of opiates are described. Little is known about the long-term effects of opiate exposure; they apparently include frequent instrumental troubles. At the present time, the rapid intervention of a multidisciplinary team is recommended, taking charge of the mothers who should receive methadone in progressively tapering doses.

    The mortality patterns of 294 Domestic Shorthair kittens indicated that birth weight was closely related to survivability. Slightly over half of the nonsurviving kittens lost at 0 to 3 days of life were stillborn. Abnormal gross anatomy did not appear to be a major factor in neonatal kitten death. Mortality was lowest at the 5th parity and in litters of 5 kittens. Litters of 1 kitten experienced high mortality. Smaller queens tended to deliver fewer kittens per litter, but with improved kitten viability. Overweight queens experienced increased mortality of kittens. Further examination of mortality by litter size also revealed that low birth weight kittens tended to survive less often than normal birth weight kittens, even within the same litter.

    Capillary blood samples from 42930 infants born in the Italian region of Emilia-Romagna were collected for 17-hydroxyprogesterone radioimmunoassays on days 2, 3, 4, 5, 6, and 7, or between days 7 and 15 of life. A microfilter paper method modified from that of Pang et al.1 was used for this assay. Pathologic values of 17-hydroxyprogesterone were found in 5 infants giving an incidence in this homogeneous Caucasian population of 1:8586. We also investigated 17-hydroxyprogesterone values in relation to the day of sampling and the possible correlation between 17-hydroxyprogesterone values and birthweight and gestational age. We concluded that neonatal screening for congenital adrenal hyperplasia caused by 21-hydroxylase deficiency was possible by this method and that the infants' maturity and the particular day of collection of the samples affect the values but not the validity of the screening.

    Jargon, the specialized vocabulary and idioms, is frequently used by people of the same work or profession. The neonatal intensive care unit (NICU) makes no exception to this. As a matter of fact, NICU is one place where jargon is constantly developing in parallel with the evolution of techniques and treatments. The use of jargon within the NICU is very practical for those who work in these units. However, this jargon is frequently used by neonatologists in medical reports or other kinds of communication with unspecialized physicians. Even if part of the specialized vocabulary can be decoded by physicians not working in the NICU, they do not always know the exact place that these techniques or treatments have in the management of their patients. The aim of this article is to describe the most frequent jargon terms used in the French NICU and to give up-to-date information on the importance of the techniques or treatments that they describe.

    Summary Background Extravaginal testicular torsion (ETT), also called prenatal or perinatal, occurs prenatally and is present at birth or appears within the first month of life. It has different etiology than intravaginal torsion, which appears later in life. Testicular torsion must be taken into consideration in differential diagnosis of acute scrotum and should be confirmed or ruled out at first diagnostic step. Ultrasonography is a basic imaging modality, however diagnostic pitfalls are still possible. There is still wide discussion concerning management of ETT, which varies from immediate orchiectomy to conservative treatment resulting in testicle atrophy. Material/Methods In this article we present ultrasonographic spectrum of ETT in neonates, which were diagnosed and treated in our hospital during the last 8 years (2008–2015), in correlation with clinical and intraoperative findings. Results Thirteen neonates with ETT were enrolled in the study – 11 patients with a single testicle affected and 2 patients with bilateral testicular torsion. Most common signs on clinical examination were: hardened and enlarged testicle and discoloration of the scrotum. Most common ultrasonographic signs were: abnormal size or echostructure of the affected testicle and absence of the blood flow in Doppler ultrasonography. In 3 patients ultrasound elastography was performed, which appeared very useful in testicle structure assessment. Conclusions Testicular torsion may concern boys even in the perinatal period. Ultrasonographic picture of acute scrotum in young boys may be confused. Coexistence of the abnormal size or echostructure of the torsed testicle with absence of the blood flow in Doppler ultrasonography appear as very specific but late ultrasonographic sings. Ultrasound elastography may be a very useful tool for visualisation of a very common clinical sign – hardening of the necrotic testicle. PMID:27757176

  14. Prevention and treatment of neonatal nosocomial infections.

    PubMed

    2017-01-01

    Nosocomial or hospital acquired infections threaten the survival and neurodevelopmental outcomes of infants admitted to the neonatal intensive care unit, and increase cost of care. Premature infants are particularly vulnerable since they often undergo invasive procedures and are dependent on central catheters to deliver nutrition and on ventilators for respiratory support. Prevention of nosocomial infection is a critical patient safety imperative, and invariably requires a multidisciplinary approach. There are no short cuts. Hand hygiene before and after patient contact is the most important measure, and yet, compliance with this simple measure can be unsatisfactory. Alcohol based hand sanitizer is effective against many microorganisms and is efficient, compared to plain or antiseptic containing soaps. The use of maternal breast milk is another inexpensive and simple measure to reduce infection rates. Efforts to replicate the anti-infectious properties of maternal breast milk by the use of probiotics, prebiotics, and synbiotics have met with variable success, and there are ongoing trials of lactoferrin, an iron binding whey protein present in large quantities in colostrum. Attempts to boost the immunoglobulin levels of preterm infants with exogenous immunoglobulins have not been shown to reduce nosocomial infections significantly. Over the last decade, improvements in the incidence of catheter-related infections have been achieved, with meticulous attention to every detail from insertion to maintenance, with some centers reporting zero rates for such infections. Other nosocomial infections like ventilator acquired pneumonia and staphylococcus aureus infection remain problematic, and outbreaks with multidrug resistant organisms continue to have disastrous consequences. Management of infections is based on the profile of microorganisms in the neonatal unit and community and targeted therapy is required to control the disease without leading to the development of more

    Background In adult humans, cerebral microbleeds play important roles in neurodegenerative diseases but in neonates, the consequences of cerebral microbleeds are unknown. In rats, a single pro-angiogenic stimulus in utero predisposes to cerebral microbleeds after birth at term, a time when late oligodendrocyte progenitors (pre-oligodendrocytes) dominate in the rat brain. We hypothesized that two independent pro-angiogenic stimuli in utero would be associated with a high likelihood of perinatal microbleeds that would be severely damaging to white matter. Methods Pregnant Wistar rats were subjected to intrauterine ischemia (IUI) and low-dose maternal lipopolysaccharide (mLPS) at embryonic day (E) 19. Pups were born vaginally or abdominally at E21-22. Brains were evaluated for angiogenic markers, microhemorrhages, myelination and axonal development. Neurological function was assessed out to 6 weeks. Results mRNA (Vegf, Cd31, Mmp2, Mmp9, Timp1, Timp2) and protein (CD31, MMP2, MMP9) for angiogenic markers, in situ proteolytic activity, and collagen IV immunoreactivity were altered, consistent with an angiogenic response. Vaginally delivered pups exposed to prenatal IUI+mLPS had spontaneous cerebral microbleeds, abnormal neurological function, and dysmorphic, hypomyelinated white matter and axonopathy. Pups exposed to the same pro-angiogenic stimuli in utero but delivered abdominally had minimal cerebral microbleeds, preserved myelination and axonal development, and neurological function similar to naïve controls. Conclusions In rats, pro-angiogenic stimuli in utero can predispose to vascular fragility and lead to cerebral microbleeds. The study of microbleeds in the neonatal rat brain at full gestation may give insights into the consequences of microbleeds in human preterm infants during critical periods of white matter development.

    The potential improvements in spatial resolution of neonatal EEG used in source localization have been challenged by the insufficiencies in realistic neonatal head models. Our present study aimed at using empirical methods to indirectly estimate skull conductivity; the model parameter that is known to significantly affect the behavior of newborn scalp EEG and cause it to be markedly different from that of an adult. To this end, we used 64 channel EEG recordings to study the spatial specificity of scalp EEG by assessing the spatial decays in focal transients using both amplitudes and between-c'hannels linear correlations. The findings showed that these amplitudes and correlations decay within few centimeters from the reference channel/electrode, and that the nature of the decay is independent of the scalp area. This decay in newborn infants was found to be approximately three times faster than the corresponding decay in adult EEG analyzed from a set of 256 channel recordings. We then generated realistic head models using both finite and boundary element methods along with a manually segmented magnetic resonance images to study the spatial decays of scalp potentials produced by single dipole in the cortex. By comparing the spatial decays due to real and simulated EEG for different skull conductivities (from 0.003 to 0.3S/m), we showed that a close match between the empirical and simulated decays was obtained when the selected skull conductivity for newborn was around 0.06-0.2S/m. This is over an order of magnitude higher than the currently used values in adult head modeling. The results also showed that the neonatal scalp EEG is less smeared than that of an adult and this characteristic is the same across the entire scalp, including the fontanel region. These results indicate that a focal cortical activity is generally only registered by electrodes within few centimeters from the source. Hence, the conventional 10 to 20 channel neonatal EEG acquisition systems give a

    Malassezia species are a part of the skin microflora of neonates. Under certain circumstances, they can cause diseases ranging from simple pustulosis to lifethreatening fungemia in newborn infants. Little information is available about the epidemiology of Malassezia species in neonates. In the present study, we successfully isolated Malassezia yeasts from 68.7% of hospitalized neonates. Using the polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFPL), M. furfur (88.06%) was identified as the most isolated species, followed in frequency by M. globosa (10.48%), M. obtusa (0.73%), and M. slooffiae (0.73%). Among the variables studied, only a longer stay in the ward resulted in a higher colonization rate. Using multiple logistic regression, only the type of hospital and ward had some effects on the colonization rate. Our results supported the hypothesis that neonates acquire Malassezia flora through direct contact with their mothers or hospital personnel.

    With the advent of antibiotic resistance, pathogenic bacteria have become a major threat in cases of neonatal sepsis; however, guidelines for treatment have not yet been standardized. In this study, 15 cases of neonatal Streptococcus agalactiae sepsis from our hospital were retrospectively analyzed. Of these, nine cases showed early-onset and six cases showed late-onset sepsis. Pathogens were characterized by genotyping and antibiotic sensitivity tests on blood cultures. Results demonstrated that in cases with early-onset sepsis, clinical manifestations affected mainly the respiratory tract, while late-onset sepsis was accompanied by intracranial infection. Therefore, we suggest including a cerebrospinal fluid examination when diagnosing neonatal sepsis. Bacterial genotyping indicated the bacteria were mainly type Ib, Ia, and III S. agalactiae. We recommend treatment with penicillin or ampicillin, since bacteria were resistant to clindamycin and tetracycline. In conclusion, our results provide valuable information for the clinical treatment of S. agalactiae sepsis in neonatal infants.

    Neonatal hypoxia-ischemia (HI) affects 60% of low birth weight infants and up to 40% of preterm births. Cell death and brain injury after HI have been shown to cause long-lasting behavioral deficits. By using a battery of behavioral tests on second generation 3-week-old rodents, we found that neonatal HI is associated with behavioral outcomes in the progeny of HI-affected parents. Our results suggest an epigenetic transfer mechanism of some of the neurological symptoms associated with neonatal HI. Elucidating the transfer of brain injury to the next generation after HI calls attention to the risks associated with HI injury and the need for proper treatment to reverse these effects. Assessing the devastating extent of HI's reach serves as a cautionary tale to the risks associated with neonatal HI, and provides an incentive to create improved therapeutic measures to treat HI.

    Chlamydia trachomatis is considered a major aetiological agent of conjunctivitis in newborns. The objective of the present study was to determine the aetiology of neonatal conjunctivitis and clinico-epidemiological correlates of chlamydial ophthalmia neonatorum. Fifty-eight newborns with signs and symptoms of conjunctivitis were studied. Conjunctival specimens were subjected to Gram staining, routine bacteriological culture, culture for Neisseria gonorrhoeae and direct fluorescent antibody (DFA) staining for diagnosis of C. trachomatis infection. C. trachomatis was detected in 18 (31%) neonates. Findings suggest that since C. trachomatis is the most common cause of neonatal conjunctivitis, routine screening and treatment of genital C. trachomatis infection in pregnant women and early diagnosis and treatment of neonatal Chlamydial conjunctivitis may be considered for its prevention and control.

    The aim of this article is to educate neonatal caregivers about metagenomics. This scientific field uses novel and ever changing molecular methods to identify how infants become colonized with microbes after birth. Publications using metagenomics appear infrequently in the neonatal literature because clinicians are unaccustomed with the analytical techniques, data interpretation, and illustration of the results. This review covers those areas. After a brief introduction of neonatal citations forthcoming from metagenomic studies, the following topics are covered: 1) the history of metagenomics, 2) a description of current and emerging instruments used to define microbial populations in human organs, and 3) how extensive databases generated by genome analyzers are examined and presented to readers.

    Illegal drug use throughout the nation is a problem of epidemic proportion. Of particular concern is drug use among pregnant women. In most cases, these women have little hope of achieving a better life for themselves or their children. Illegal drugs, cocaine in particular, can have devastating effects on the neonate. These effects can last well into childhood and can exhibit themselves in academic, social, and family situations. Challenges for the neonatal nurse include early identification of these infants and use of available resources. This article addresses prenatal cocaine use and support services for drug-dependent women, effects of cocaine during the neonatal period, possible neonatal and infant outcomes, and implications for nursing practice.

    The occurrence of natal and neonatal teeth is an uncommon anomaly, which for centuries has been associated with diverse superstitions among different ethnic groups. Natal teeth are more frequent than neonatal teeth, with the ratio being approximately 3 : 1. It must be considered that natal and neonatal teeth are conditions of fundamental importance not only for a dental surgeon but also for a paediatrician since their presence may lead to numerous complications. Early detection and treatment of these teeth are recommended because they may induce deformity or mutilation of tongue, dehydration, inadequate nutrients intake by the infant, and growth retardation, the pattern and time of eruption of teeth and its morphology. This paper presents a concise review of the literature about neonatal teeth. PMID:24024038

    Neonatal communication intervention is important in South Africa, which has an increased prevalence of infants born with risks for disabilities and where the majority of infants live in poverty. Local literature showed a dearth of information on the current service delivery and roles of speech-language therapists (SLTs) and audiologists in neonatal nurseries in the South African context. SLTs have the opportunity to provide the earliest intervention, provided that intervention is well-timed in the neonatal nursery context. The aim of the research was to compile a locally relevant neonatal communication intervention instrument/tool for use by SLTs in neonatal nurseries of public hospitals. The study entailed descriptive, exploratory research. During phase 1, a survey was received from 39 SLTs and 2 audiologists in six provinces. The data revealed that participants performed different roles in neonatal nurseries, which depended on the environment, tools, materials and instrumentation available to them. Many participants were inexperienced, but resourceful in their attempts to adapt tools/materials. Participants expressed needs for culturally appropriate and user-friendly instruments for parent guidance and staff/team training on the topic of developmental care. During phase 2, a tool for parent guidance titled Neonatal communication intervention programme for parents was compiled in English and isiZulu. The programme was piloted by three participants. Suggestions for enhancements of the programme were made, such as providing a glossary of terms, adapting the programme's language and terminology, and providing more illustrations. SLTs and audiologists must contribute to neonatal care of high-risk infants to facilitate development and to support families.

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is an opportunistic pathogen that colonizes the gastrointestinal and genitourinary tracts of up to 50% of healthy adults and newborns; it is responsible for significant morbidity and mortality. Early detection can be used to establish the use of antibiotic prophylaxis to significantly reduce neonatal sepsis. This article reviews methods of detection and prevention of GBS infection in the neonate. PMID:24358406

    It is widely admitted that neonates' platelet counts (PCs) are always normal in babies born to mothers with incidental gestational thrombocytopaenia. However, results of PC determinations at delivery have led us to wonder whether incidental gestational thrombocytopaenia is actually safe for the neonate under all circumstances, and to recommend that for every baby born to a mother with a pregnancy-associated thrombocytopaenia, even in the case of confirmed IGT, platelet counts on umbilical cord blood be closely monitored.

    Automated health monitoring and alert system development is a demanding research area today. Most of the currently available monitoring and controlling medical devices are wired which limits freeness of working environment. Wireless sensor network (WSN) is a better alternative in such an environment. Neonatal intensive care unit is used to take care of sick and premature neonates. Hypothermia is an independent risk factor for neonatal mortality and morbidity. To prevent it an automated monitoring system is required. In this Letter, an automated neonatal health monitoring system is designed using sensor mobile cloud computing (SMCC). SMCC is based on WSN and MCC. In the authors' system temperature sensor, acceleration sensor and heart rate measurement sensor are used to monitor body temperature, acceleration due to body movement and heart rate of neonates. The sensor data are stored inside the cloud. The health person continuously monitors and accesses these data through the mobile device using an Android Application for neonatal monitoring. When an abnormal situation arises, an alert is generated in the mobile device of the health person. By alerting health professional using such an automated system, early care is provided to the affected babies and the probability of recovery is increased.

    We reviewed etiology and outcome of consecutive neonates admitted to a neonatal unit for investigation of parent-reported fever (116 neonates over 24 months). Tympanic temperature was measured at the emergency department (Te) and core temperature at the neonatal unit (Tn). Microbials were isolated in 27 patients (23%); Te and Tn were both <38°C in 13 (48%) of the 27 patients. Microbial isolation was associated with older median age (16.7 vs. 8.0 days, p = 0.004), empirical antibiotic commencement (p = 0.0003) and longer hospital stay (median 8 vs. 4.0 days, p = 0.004). Compared with respiratory viral infection, patients with bacteremia had high C-reactive protein (p = 0.005) and likely to have comorbidity of meningitis (p = 0.077). Te ≥38°C had the highest sensitivity, positive likelihood ratio and positive and negative predictive ratios for bacteremia. Parent-reported fever was associated with a 3% incidence of meningitis, 6% of bacteremia and 9% of urinary tract infection. The majority of neonates with parent-reported fever do not have serious bacterial infection. Nevertheless, recommendations about threshold of antibiotic initiation are difficult, and empirical systemic antibiotic coverage must be commenced in those neonates with Te ≥38°C or elevated C-reactive protein.

    We retrospectively analyzed the data of 24 children (whereof 11 neonates), with non-central venous line-related and nonmalignancy-related venous thromboembolism (VTE) at uncommon sites, referred to our Unit from January 1999 to January 2012. Thirty patients who also suffered deep vein thrombosis, but in upper/low extremities, were not included in the analysis. The location of rare site VTE was: portal (n=7), mesenteric (n=2) and left facial vein (n=1), spleen (n=3), lung (n=3), whereas 10 neonates developed renal venous thrombosis. The majority of patients (91.7%) had at least 1 risk factor for thrombosis. Identified thrombophilic factors were: antiphospholipid antibodies (n=2), FV Leiden heterozygosity (n=6), MTHFR C677T homozygosity (n=4), protein S deficiency (n=2), whereas all neonates had age-related low levels of protein C and protein S. All but 6 patients received low-molecular-weight heparin, followed by warfarin in 55% of cases, for 3 to 6 months. Prolonged anticoagulation was applied in selected cases. During a median follow-up period of 6 years, the clinical outcome was: full recovery in 15 patients, evolution to both chronic portal hypertension and esophageal varices in 2 children, and progression to renal failure in 7 of 10 neonates. Neonates are greatly vulnerable to complications after VTE at uncommon sites, particularly renal. Future multicentre long-term studies on neonatal and pediatric VTE at unusual sites are considered worthwhile.

    Neonatal sepsis is a significant cause of morbidity and mortality among term and preterm infants. Ampicillin and gentamicin are standard empiric therapy for early onset sepsis. Four cases of neonatal sepsis secondary to Escherichia coli (E. coli) found to be gentamicin resistant occurred within a five week period in one neonatal intensive care unit (NICU). To determine whether these cases could be tied to a single vector of transmission, and to more broadly evaluate the incidence of gentamicin resistant strains of E. coli in the neonatal population at our institution compared to other centers, we reviewed the charts of the four neonates (Infants A through D) and their mothers. The E. coli isolates were sent for Pulse Field Gel Electrophoresis (PFGE) to evaluate for genetic similarity between strains. We also reviewed all positive E. coli cultures from one NICU over a two year period. Infants A and B had genetically indistinguishable strains which matched that of urine and placental cultures of Infant B's mother. Infant C had a genetically distinct organism. Infant D, the identical twin of Infant C, did not have typing performed. Review of all cultures positive for E. coli at our institution showed a 12.9 percent incidence of gentamicin-resistance. A review of other studies showed that rates of resistance vary considerably by institution. We conclude that gentamicin-resistant E. coli is a relatively uncommon cause of neonatal sepsis, but should remain a consideration in patients who deteriorate despite initiation of empiric antibiotics.

    Objective: Although numerous studies have found higher rates of abortion and still births following consanguinity (familial marriages), the question of whether consanguinity significantly increases the risk of neonatal death has inadequately been addressed.This study aims to evaluate familial marriage effects on neonatal death in rural areas in Iran. Materials and methods: In this nested case-control study, 6900 newbornswho were born in rural areas of Kohgiluyeh and Boyerahmad Province (South-West of Iran)were followed till the end of neonatal period, and neonatal death was the outcome of interest. Subsequently 97 cases and 97 controls were selected in study cohort by using risk set sampling model. Crude and adjusted odds ratios (OR) were estimated by usinga conditional logistic regression model. Results: In the final model, prematurity (OR = 5.57), low birthweight (LBW) (OR = 7.68), consanguinity (first cousins) (OR = 5.23), C-section (OR = 7.27), birth rank more than 3 (OR = 6.95) and birthsinterval less than 24 months (OR = 4.65) showed significant statistical association with neonatal mortality (p < 0.05). Conclusion: According to our findings, after adjusting the effects of other significant risk factors, familial marriageto first cousins is considered asan important risk factor for neonatal death.

    Rats subjected to stressful stimuli during the stress hyporesponsive period exhibit varied neuroendocrine and behavioral changes as neonates, adolescents and adults. The current work examined the effects of neonatal isolation stress, using a within-litter design, on adult anxiety-related behavior and endocrine stress reactivity. Neonatal rats were isolated daily for 1 hr from postnatal day (P) 4-9, a manipulation previously shown to induce hypothalamic-pituitary-adrenal (HPA) responses on P9 (Knuth and Etgen, 2005). Control animals were either handled briefly or left undisturbed (with-dam). Adult rats were tested for anxiety-related behavior using the elevated plus maze and open field, and for endocrine responses following restraint stress. Neonatal isolation decreased center exploration of the open field following 1 hr restraint, including decreased time in the center compared to with-dam or handled controls, and decreased center entries and distance traveled in the center compared to with-dam controls. It also decreased time in and entries into the open arms of the elevated plus maze compared to handled controls, suggesting enhanced anxiety-related behavior. Neonatal isolation had no effect on basal or restraint-induced levels of ACTH or corticosterone. These findings indicate that neonatal isolation may enhance anxiety-related behaviors, especially in response to stress, without altering HPA function.

    Neonatal hemochromatosis is a rare congenital disorder of the liver associated to a poor prognosis. Liver transplantation is often required, since no effective medical treatment has been found. Despite mounting evidence of an alloimmune etiology of this condition, exchange transfusion has never been proposed as a specific treatment for neonatal hemochromatosis. Here we describe two siblings affected by neonatal hemochromatosis. The first, a female, died at 18 days of severe coagulopathy and acute renal failure, diagnosed as affected by neonatal hemochromatosis only when the second sibling was suspected as being affected by the same disease. The second child showed a rapidly worsening coagulopathy which was treated with two exchange transfusions, followed by rapid clinical and laboratory improvement, before reaching a definite diagnosis of neonatal hemochromatosis. He is healthy at present after a follow-up of 12 months. Although exchange transfusion has never been considered as treatment for neonatal hemochromatosis, this case suggests that it could be a feasible treatment option for children affected by this disease, as for other alloimmune conditions.

    Introduction Invasive candidiasis is responsible for approximately 10% of nosocomial sepsis in very-low-birth-weight (VLBW) infants and is associated with substantial morbidity and mortality. Over the last 2 decades, the antifungal armamentarium against Candida spp. has increased; however, efficacy and safety studies in this population are lacking. Areas covered We reviewed the medical literature and extracted information on clinical and observational studies evaluating the use of antifungal agents in neonates with invasive candidiasis. Expert opinion Efficacy and safety data for antifungals in neonates are lacking, and the majority of studies conducted to date have concentrated on pharmacokinetic/pharmacodynamic evaluations. Unlike other anti-infective agents, efficacy data in the setting of neonatal candidiasis cannot be extrapolated from adult studies due to differences in the pathophysiology of the disease in this population relative to older children and adults. Data collected thus far or data submitted to regulatory agencies for amphotericin B deoxycholate, fluconazole, and micafungin suggest that these are the current agents of choice for this disease in neonates until data for newer antifungal agents become available. For prophylaxis, data from fluconazole randomized controlled trials will be submitted to the regulatory agencies for labeling. Ultimately, the field of therapeutics for neonatal candidiasis will require multidisciplinary collaboration given the numerous challenges associated with conducting clinical trials in neonates.

    Seizures are the most common neurological emergencies in the neonatal period and are associated with poor neurodevelopmental outcomes. Seizures affect up to five per 1000 term births and population-based studies suggest that they occur even more frequently in premature infants. Seizures are a sign of an underlying cerebral pathology, the most common of which is hypoxic-ischaemic encephalopathy in term infants. Due to a growing body of evidence that seizures exacerbate cerebral injury, effective diagnosis and treatment of neonatal seizures is of paramount importance to reduce long-term adverse outcomes. Electroencephalography is essential for the diagnosis of seizures in neonates due to their subtle clinical expression, non-specific neurological presentation and a high frequency of electro-clinical uncoupling in the neonatal period. Hypoxic-ischaemic encephalopathy may require neuroprotective therapeutic hypothermia, accompanying sedation with opioids, anticonvulsant drugs or a combination of all of these. The efficacy, safety, tolerability and pharmacokinetics of seven anticonvulsant drugs (phenobarbital, phenytoin, levetiracetam, lidocaine, midazolam, topiramate and bumetanide) are reviewed. This review is focused only on studies reporting electrographically confirmed seizures and highlights the knowledge gaps that exist in optimal treatment regimens for neonatal seizures. Randomised controlled trials are needed to establish a safe and effective treatment protocol for neonatal seizures.

    Urinary tract infection (UTI) is one of the most common bacterial infections. Maternal UTI is a risk factor for neonatal UTI. The aim of the present study was to determine the severity of renal inflammation in neonate rats born from mothers with induced UTI. Twelve pregnant rats (Sprague-Dawley) were included in study. The rats were divided into two groups (six rats in each group). In the first group, pyelonephritis was induced in the third trimester of pregnancy and the second group was used as a control group. After delivery, the neonates were divided into three groups based on days after birth (the 1 st, 3 rd and 7 th days after birth). In each group, two neonates of each mother were killed and a midline abdominal incision was made and both kidneys were aseptically removed. On the 7 th day, rat mothers were killed and their kidneys were removed. The preparations were evaluated with a bright field microscope for inflammatory response. Renal pathology showed inflammation in all UTI-induced mothers, but only two cases of neonates (2.1%) showed inflammation in the renal parenchyma. There was no relation between the positive renal culture and the pathological changes. We conclude that neonates with UTI born to UTI-induced mothers showed a lesser inflammatory response.

    Inadequate pain management but also inappropriate use of analgesics in early infancy has negative effects on neurodevelopmental outcome. As a consequence, neonatal pain management is still in search for the Holy Grail. At best, effective pain management is based on prevention, assessment, and treatment followed by a re-assessment of the pain to determine if additional treatment is still necessary. Unfortunately, epidemiological observations suggest that neonates are undergoing painful procedures very frequently, unveiling the need for effective preventive, non-pharmacological strategies. In addition, assessment is still based on validated, multimodal, but subjective pain assessment tools. Finally, in neonatal intensive care units, there is a shift in clinical practices (e.g., shorter intubation and ventilation), and this necessitates the development and validation of new pharmacological treatment modalities. To illustrate this, a shift in the use of opioids to paracetamol has occurred and short-acting agents (remifentanil, propofol) are more commonly administered to neonates. In addition to these new modalities and as part of a more advanced approach of the developmental pharmacology of analgesics, pharmacogenetics also emerged as a tool for precision medicine in neonates. To assure further improvement of neonatal pain management the integration of pharmacogenetics with the usual covariates like weight, age and/or disease characteristics is needed.

    Context: Neonatal conjunctivitis is associated with poor prenatal care worldwide. Purpose: Data on neonatal conjunctivitis is scarce in Malawi. This study describes risk factors associated with conjunctivitis in neonates born in a large tertiary care hospital in Blantyre, Malawi. Materials and Methods: Medical records of a retrospective cohort of 231 neonates diagnosed with conjunctivitis from January 2006 to December 2009 at a large tertiary hospital in Malawi were reviewed. All subjects were clinically diagnosed with ophthalmia neonatorum. Data were collected on patient demographics and clinical features. The frequencies were calculated of various risk factors in neonates with ophthalmia neonatorum and their mothers as well as the treatments administered. Results: Mean age of the mother was 23.45 years (range, 15-40 years), and the mean number of previous deliveries was 2.3 (range, 1-7) children. Nearly, 80% of mothers delivered preterm infants via spontaneous vaginal delivery. The mean birth weight of neonates was 2869.6 grams (1100-5000 grams). Among mothers, premature rupture of membranes was the leading risk factor (24%) followed by sepsis during labor (9%), and history of sexually transmitted infections (STI) (7%). Neonates presented with low Apgar scores (19%), fever (8%), and/or meconium aspiration (5%). Providers treated patients empirically with a varied combination of benzyl penicillin, gentamicin, tetracycline eye ointment, and saline eye wash. Tetracycline with a saline eyewash was used frequently (34%) compared with combinations of benzyl penicillin and gentamicin. Conclusions: Improving prenatal care to reduce sepsis, traumatic deliveries, and early diagnosis of STI with appropriate treatment may potentially reduce vertical transmission of neonatal conjunctivitis in this understudied population.

    Women who desire to breast-feed their sick newborns often encounter obstacles, including insufficient support and education as well as unsupportive hospital practices. The purpose of this study was to describe maternal, neonatal, and outside influences associated with the intention, initiation, and duration of breast-feeding for women whose newborns were admitted to the neonatal intensive care unit. One hundred mothers were interviewed. Most mothers (67%) intended to breast-feed exclusively and this was significantly related to maternal characteristics such as age, education, parity, smoking and marital status, pre-breast-feeding experience, and the influences of the neonate's father and prenatal education. Seventy-eight mothers initiated pumping. Initiation was significantly related to maternal education, smoking, parity, previous breast-feeding experience, the neonate's physician, the neonate's father, and postpartum breast-feeding education. Fifty-four mothers were followed up by telephone after discharge until weaning. Thirty percent were exclusively breast-feeding at 2 weeks after discharge, and 15% were breast-feeding at 1 year. Duration of breast-feeding was significantly associated with education, marital status, ethnicity, income, assistance from nurses and lactation consultants, and feeding method along with milk type and milk volume at discharge. Increased family support, timely breast-feeding information, and a supportive neonatal intensive care unit environment are needed for women to succeed in breast-feeding their hospitalized newborns.

    Extra-renal pelvis (ERpel) is a common ultrasonographic finding among neonates who have undergone recurrent ultrasound examinations for a better definition of prenatal renal pelvic dilatation. This study tries to determine whether or not ERpel has important prognostic implications. Seventy-nine neonates (17 female) were examined. All had a diagnosis of prenatal renal pelvis dilatation, which was shown by postnatal ultrasound to be ERpel. Sixty ERpel neonates were examined 1.5 months to 2.5 months after the ultrasound (US) diagnosis by both Tc-99m diethylene triamine penta-acetic acid (DPTA) dynamic renal scanning and (99m)Tc-pertechnetate direct cystography. Clinical assessment, urine cultures and renal ultrasound follow-up were maintained for 2 years. The proportion of urinary tract infections (UTIs) in patients with ERpel was compared with that of the total neonatal and infantile population with normal US scans in the region of our hospital. Associated minor congenital malformations were found in 12 of 79 neonates (15.2%). Four had a family history of ERpel. Among 60 neonates who underwent renal scanning, 36 (60%) were found to have urinary retention in the collecting system. Another nine (15%) had vesico-ureteral (VU) reflux, of which seven had urinary retention. Fifteen (25%) showed normal isotope imaging. Urinary tract infection was diagnosed in 16 ERpel neonates in whom only one exhibited VU reflux (grade 2). The incidence of neonatal UTI in the ERpel group was more than that of either neonatal or infantile UTI in those with normal US scans in the local population (20.2% vs 1.2% and 4.3%, respectively). Fifty-three infants completed a 2-year follow-up. Repeat renal ultrasonography indicated that one infant (1.8%) had developed bilateral hydronephrosis, 12 (22.6%) had unchanged findings, 18 (40%) showed an improvement (decrease of ERpel width or resolution in one side) and, in 22 (41.5%) infants, the condition had resolved.

    1. Responses were recorded from individual tactile afferent fibres isolated by microdissection from the median nerve of pentobarbitone-anaesthetized neonatal kittens (1-5 days post-natal age). Experiments were also conducted on adult cats to permit precise comparisons between neonatal and adult fibres. 2. Neonatal fibres with receptive fields on the glabrous skin of the foot pads were classified into two broad groups, a slowly adapting class (40%) which responded throughout a 1 sec period of steady indentation and a rapidly adapting or dynamically sensitive class comprising 60% of units. Fibres in these two groups had overlapping conduction velocities in the range 4·3 to 7·5 m/sec and were believed to be the developing Group II afferents of the adult. 3. Neonatal slowly adapting fibres qualitatively resembled their adult counter-parts. They displayed graded stimulus-response relations which, over the steepest segment of the curves, had mean slopes of 15·7 impulses/100 μm of indentation. Plateau levels of response were often reached at amplitudes of skin indentation of < 0·5-0·7 mm. 4. Dynamically sensitive fibres with receptive fields on the glabrous skin were studied using sinusoidal cutaneous vibration which in the adult enables them to be divided into two distinct classes. However, in the neonate, they formed a continuum whether criteria of sensitivity or responsiveness were used. 5. In response to vibration neonatal fibres differed from adult ones according to the following quantitative indices: (i) sensitivity as measured by both absolute thresholds and thresholds for a 1: 1 pattern of response, both of which were higher in the neonate than in the adult at all frequencies > 50 Hz and differed by an order of magnitude at frequencies ≥ 200 Hz; (ii) responsiveness based on the mean impulse rate evoked at a fixed amplitude of cutaneous vibration; (iii) band width of vibratory sensitivity which in the neonate was confined to approximately 5-300 Hz whereas

    Neonatal pneumonia is reported to be the primary cause of neonatal respiratory failure and one of the common causes of neonatal hospitalization and death in developing countries. Chest X-ray was considered the gold standard for diagnosis of neonatal pneumonia. Lung ultrasonography has been described as a valuable noninvasive tool for the diagnosis of many neonatal pulmonary diseases. We report a case of ventilation associated neonatal pneumonia with very early diagnosis using lung ultrasound before any significant radiographic changes in chest X-ray or laboratory findings suggestive of infection.

    Neonatal sepsis is a leading cause of neonatal mortality. Congenital heart disease accounts for additional risk of sepsis in neonates. Here we report a case of Down's syndrome with late onset neonatal sepsis associated with multiple superficial skin abscesses simulating staphylococcal infection. The baby was empirically treated with vancomycin. Subsequently, multidrug resistant Klebsiella pneumoniae was detected from both pus and blood culture. Change to appropriate antibiotic resulted in clinical recovery. Although sepsis is one of the major ailments in neonates, atypical presentations of neonatal sepsis in Down's syndrome patients are underreported. Here we highlight the atypical presentation of Klebsiella sepsis and the importance of early antibiogram in such cases.

    Poor neonatal survival constrains productivity and good welfare. The heritability of survival in sheep is very low, suggesting that genetic progress will be slow. Previously we have shown that a difficult birth and low neonatal lamb vigor are important predictors of future survival. In this study we investigated the heritability of these traits, and their relationship to production traits, as an alternative indirect route to improve lamb survival. Neonatal lamb data from 11,092 animals were collected over 2 years from 290 commercial sheep flocks, using previously developed methods to rapidly assess three traits (birth assistance, lamb vigor, sucking ability) on farm. Heritabilities for neonatal traits were moderate: birth assistance (mean ± standard error; 0.26 ± 0.03), lamb vigor (0.40 ± 0.04) and sucking ability (0.32 ± 0.03). Genetic correlations between neonatal traits were moderate to high, and positive. Heritabilities for production traits were also moderate: 8-week weight (0.27 ± 0.06), 20-week weight (0.39 ± 0.07), ultrasound muscle depth (0.37 ± 0.06). Genetic and phenotypic correlations between the neonatal traits and production traits were not significantly different from zero. However, lambs that were scored as of poor vigor at birth were less likely to be recorded at 8 or 20 weeks, indicating that they may have died. The data demonstrate that the neonatal survival traits of birth assistance, lamb vigor and sucking assistance are moderately heritable when treated as a lamb trait, indicating that selection to target these lamb traits would successfully, and efficiently, improve survival without influencing productivity.

    Hypothesis Nitrotyrosine, a reaction product of peroxynitrite and proteins, could be demonstrated in the postmortem examination of brain tissue of full‐term neonates who had severe perinatal asphyxia. Methods The brain tissue of 22 full‐term neonates who died after severe perinatal asphyxia was examined, including cerebral cortex, basal ganglia, thalamus, hippocampus, brain stem, olives and cerebellum. Median age at death was 52 h. Routine histopathological examination and additional immunohistological staining were carried out with anti‐cysteine protease protein 32 antibodies to detect activated caspase 3, anti‐nitrotyrosine antibodies to detect nitrotyrosine and anti‐CD68 antibodies to detect activated microglia and macrophages, which might be associated with the production of nitric oxide. Staining was scored as none, weak (1–25% positive cells), moderate (26–75% positive cells) or severe (>75% positive cells). Results 14 patients showed global injury, 4 showed injury of the basal ganglia and thalamus, and 4 showed predominantly parasagittal brain injury. One neonate without perinatal asphyxia served as a control. Nitrotyrosine staining of neurones was shown in all neonates with asphyxia, mostly in the thalamus (70%) and inferior olives (68%). Total nitrotyrosine staining tended to be less in the base of the pons and inferior olives of neonates with parasagittal brain injury. Activated caspase 3 was found mostly in the thalamus (60%) and hippocampus (53%). Positive CD68 staining was mainly present in the thalamus (70% positive). Conclusion Nitrotyrosine was found in brain tissue of full‐term neonates, suggesting that nitric oxide toxicity might have a role in hypoxic–ischaemic brain injury at term. This may be relevant for neuroprotective strategies in full‐term neonates with perinatal asphyxia. PMID:16835259

    Exposure to prenatal and early-life stress results in alterations in neural connectivity and an increased risk for neuropsychiatric disorders. In particular, alterations in amygdala connectivity have emerged as a common effect across several recent studies. However, the impact of prenatal stress exposure on the functional organization of the amygdala has yet to be explored in the prematurely-born, a population at high risk for neuropsychiatric disorders. We test the hypothesis that preterm birth and prenatal exposure to maternal stress alter functional connectivity of the amygdala using two independent cohorts. The first cohort is used to establish the effects of preterm birth and consists of 12 very preterm neonates and 25 term controls, all without prenatal stress exposure. The second is analyzed to establish the effects of prenatal stress exposure and consists of 16 extremely preterm neonates with prenatal stress exposure and 10 extremely preterm neonates with no known prenatal stress exposure. Standard resting-state functional magnetic resonance imaging and seed connectivity methods are used. When compared to term controls, very preterm neonates show significantly reduced connectivity between the amygdala and the thalamus, the hypothalamus, the brainstem, and the insula (p < 0.05). Similarly, when compared to extremely preterm neonates without exposure to prenatal stress, extremely preterm neonates with exposure to prenatal stress show significantly less connectivity between the left amygdala and the thalamus, the hypothalamus, and the peristriate cortex (p < 0.05). Exploratory analysis of the combined cohorts suggests additive effects of prenatal stress on alterations in amygdala connectivity associated with preterm birth. Functional connectivity from the amygdala to other subcortical regions is decreased in preterm neonates compared to term controls. In addition, these data, for the first time, suggest that prenatal stress exposure amplifies these

    Childhood mortality in Upper River Division, The Gambia is high, 99 per 1000 mid-year population, and 27% of deaths occur is the neonatal period. The aims of the present study were to describe patterns of neonatal death and to identify risk factors. Cause of death was investigated using a neonatal post-mortem questionnaire, and a population-based, matched case-control study was conducted to identify potential risk factors. The neonatal mortality rate in Upper River Division was 39 per 1000 live births (95% CI 36.8-41.2). The rates in the early and late neonatal periods were 21.0 (19.4-22.6) and 18.0 (16.5-19.5), respectively. Infection accounted for 57% of all deaths. In the early neonatal period, 30% of deaths were due to prematurity. Only 55% of babies who died presented for treatment and 84% died at home. Risk factors for neonatal death were primiparity (OR 2.18), previous stillbirth (OR 3.19), prolonged labour (OR 2.80) and pre-lacteal feeding (OR 3.38). A protective effect was seen in association with delivery by a trained traditional birth attendant (OR 0.34) and the application of shea nut butter, a traditional medicine, to the cord stump (OR 0.07). This study has identified the need to understand the reasons underlying the widespread use of pre-lacteal feeds and the barriers to health service use in this community in order to plan effective interventions.

    Vaccine-preventable diseases constitute a major health problem contributing to the morbidity and mortality in many developing countries including Egypt. WHO adopted resolutions to eradicate poliomyelitis by the year 2000, eliminate neonatal tetanus by the year 1995, and reduce measles mortality by 95% and morbidity by 90%, compared to the pre-immunization levels by 1995. Evaluation of preventive programs for these diseases necessitates availability of up to date information on their occurrence. The present study was undertaken to determine the current epidemiological features of poliomyelitis, neonatal tetanus and measles, to identify the trends of these diseases as well as to determine their outcomes and hospital loads. Data about the admitted cases of poliomyelitis, neonatal tetanus and measles were collected from the hospital register of Alexandria fever hospital for five successive years (1992-96). Available information on age, sex, residence, diagnosis, outcome of treatment, dates of admission and discharge were collected. The total number of cases of the three diseases admitted to the hospital during the period 1992-96 were 1406, measles represented 85.4%, neonatal tetanus 13.9% and poliomyelitis 0.7%. The results revealed that in the year 1994 only one case of poliomyelitis was admitted and since then no other cases were reported. The number of measles cases increased gradually in the latter years and about 78% of them were older than five years of age. A significant increase in the age of measles occurrence was observed. A gradual decline in the number of neonatal tetanus cases was observed. These cases were more apt to occur among early neonates but still clustered in certain geographical areas. The results of the study pinpoint the long term impact of the well run program aiming at eradicating poliomyelitis in Alexandria. However, for elimination of neonatal tetanus and controlling measles morbidity, further activities are required including strengthening

    Hyperbilirubinemia is a common problem in neonates and causes serious complications. Thus, serial measurements of bilirubin should be done. This assessment is done through two methods of laboratory measurement in serum sample and transcutaneous bilirubinometer. This descriptive study compared transcutaneous bilirubin assessment and laboratory serum bilirubin. Bilirubin level was assessed among 256 neonates admitted to the Qods Children's Hospital in Qazvin- Iran, because of neonatal indirect jaundice, through two methods of transcutaneous bilirubinometery from two sites of forehead and sternum and laboratory measurement of bilirubin in serum. The cases were non-hemolytic icteric term neonates weighing 2500 gram or more and had not received phototherapy or other treatments. Neonates with hemolytic forms of jaundice, sepsis and suspicious to metabolic disorders were excluded. Assessments by means of KJ-8000 transcutaneous bilirubinometer from two sites of forehead and sternum and through laboratory measurement of serum bilirubin were registered and analyzed. The results of the current study showed that there was a correlation of 0.82 between serum bilirubin and transcutaneous forehead bilirubin assessment and for the used device sensitivity of 0.844; specificity of 0.842, Youden Index of 0.709 and Shortest of 0.042 for a cut-off of 12.4 in bilirubin of participants. Furthermore, Likelihood Ratio positive and negative (LR) were 5.665 and 0.164, respectively and diagnostic Odds Ratio (LR+/LR-) was 34.56. Transcutaneous bilirubinometery can be considered as a reliable tool to assess bilirubin for the screening of neonatal jaundice in term neonates.

  18. Why Thailand should consider promoting neonatal circumcision?

    Male circumcision (MC) has been proven to reduce the risk of HIV transmission. The WHO and UNAIDS jointly recommend the international community consider MC as an HIV prevention measure. MC reduces the risk of acquiring other sexually transmitted infections (STIs) among men, urinary tract infections among children and penile cancer. Lowering the prevalence of STIs in men may reduce the incidence of STIs among women. High levels of adult MC are difficult to achieve in cultures where it has not been customary. Adult MC is associated with a high prevalence of post-operative complications. Neonatal male circumcision (NC) is simpler, safer, and cheaper. Higher coverage with MC can be achieved through NC. Thailand is a good country to promoting NC for the following reasons: most HIV infections are contracted through heterosexual transmission, there is a low MC rate, most newborn deliveries occur in hospitals, there is a relatively strong health care infrastructure and Thailand has well developed HIV care services. Issues of concern regarding promoting NC include length of time before seeing benefits, cost effectiveness of the intervention, the burden to the health care delivery system and concerns about children's rights. NC is an efficacious HIV prevention strategy that should be considered by those involved in HIV/AIDS prevention planning in Thailand. Further studies are needed to determine whether NC should be promoted in Thailand.

    Neonatal alloimmune thrombocytopaenia (NAIT) results from a fetomaternal incompatibility with maternal sensitisation against a fetal human platelet antigen (HPA) and antibodies transfer to the fetal circulation, leading to platelet destruction. The clinical presentation is variable and isolated intraocular haemorrhage is rare. We present the case of a male newborn, with intrauterine growth restriction, born at 29 weeks due to pre-eclampsia. He presented proptosis of the left eye, hyphaema and elevated intraocular pressure, with no other signs of haemorrhage. Severe thrombocytopaenia was found (27×10(9)/L). Perinatal infection and maternal thrombocytopaenia were excluded. Positive anti-HPA-1a and antihuman leucocyte antigen class I alloantibodies were found in the mother. Platelet crossmatch between the father's platelets and mother's plasma was positive. Platelet transfusions and intravenous immunoglobulin were given with favourable response. This case highlights an unusual presentation of NAIT, which should be suspected in the presence of severe thrombocytopaenia in the first 24-72 h of life.

    A bacteriological work on surface infections was done among live births (study group I) and neonates admitted in hospital (study group II). Out of 134 cases of conjunctivitis in group I Gram-negative bacilli predominated (48.5%) with Escherichia coli accounting for 29 (14.9%) cases, Klebsiella species 15 (11.2%) cases, Citrobacter freundii 3 (2.2%) cases, Pseudomons aeruginosa 18 (13.4%) cases and Aeromonas hydrophila 3 (2.2%) amongst pure isolates (73.9%). Gonococcus was noted in 2 (1.5%) cases. In group II, 41.7% were Staphylococcus aureus in pure growth (75%), compared to only 9.0% in group I. Skin infections were caused by both Staphylococcus aureus and Staphylococcus epidermidis. Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa were the principal insolates from umbilical sepsis. Pseudomonas aeruginosa was isolated as pure growth from local site of noma neonatorum. Anaerobic cultures were negative in all except in 2 cases of umbilical sepsis with tetanus neonatorum revealing Clostridium tetani which however proved to be non-toxigenic. Blood cultures were positive in 4 out of 14 cases bearing 50% correlation with bacteria from surface infections. A source study established partial correlation with the cases of pseudomonas conjunctivitis. Phage typing of Staphylococcus aureus and biochemical typing failed to detect any definite marker of clinical entities, except that the skin infections were caused by group III phages predominantly (65.0%).

    Severe combined immunodeficiencies (SCID) are a group of inherited diseases of the immune system characterized by profound abnormalities of T-cell development. Infants with SCID require prompt clinical intervention to prevent life-threatening infection and studies show significantly improved survival in babies diagnosed at birth based on previous family history. SCID follows the criteria for population-based newborn screening because it is asymptomatic at birth and fatal within the 1st year of life if there is no intervention, the confirmation of the disease is easy, there is a curative treatment, and it is known that early hematopoietic stem cell transplantation significantly improves survival, the quality of immune reconstitution, and quality of life. Quantification of T-cell receptor excision circles (TRECs) in DNA extracted from Guthrie samples is a sensitive and specific screening test for SCID. We conducted a nationwide prospective study of neonatal screening of SCID in a population of 200,000 French newborns over a period of 2 years. The objective was to study the clinical utility and the cost-effectiveness ratio, and to demonstrate that universal SCID screening could result in a substantial benefit to detect individuals, making screening relatively cost-effective in spite of the low incidence of the disease.

    The brain and the immune system are the two major adaptive systems of the body. During an immune response the developing neonatal brain and the immune system "cross-talk" and this course of action is essential for maintaining homeostasis. Two pathway are involved in this intercommunication: the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). This overview focuses on the role of SNS in neuroimmune interactions, an area that has received much less attention than the role of HPA axis. Evidence suggests that norepinephrine (NE) is a neurotransmitter/neuromodulator in different organs and tissues. Under stimulation, NE is released from the sympathetic nerve terminals in these organs and tissues .Through stimulation of specific receptors, locally released NE, or circulating catecholamines such as epinephrine, affect lymphocyte traffic, circulation, and proliferation, and modulate cytokine production and the functional activity of different lymphoid cells. In addition, recent evidence is discussed that NE and epinephrine, through stimulation of the beta(2)-adrenoreceptor-cAMP-protein kinase A pathway, inhibit the production of type 1/proinflammatory cytokines, such as interleukin (IL-12), tumor necrosis factor-alpha, and interferon-gamma by antigen-presenting cells and T helper (Th) 1 cells, whereas they stimulate the production of type 2/anti-inflammatory cytokines such as IL-10 and transforming growth factor-beta. Thus, the activation of SNS during an immune response might be aimed to localize the inflammatory response.

    Colors have always attracted our fantasy and imagination. Medicine, like many other human activities, did not escape their attraction, sometimes with fatal consequences. The scientific literature, magazines, etc. are full of reports on the beneficial, miraculous effects of colors. Even nowadays, where photobiology and photomedicine have been put on very firm bases, chromopaths are still at work. The evolution of light therapy from chromotherapy to photomedicine is presented in brief, with the aim of contributing to the action against the unscientific behavior of researchers and clinicians who support biological and/or clinical results without serious and well documented work. Colors have played an important role in the phototherapy of neonatal jaundice. It is an interesting example of how even a rigorous scientific search for the optimal color has progressed in part by change, due to the lack of an action spectrum, too hurried extrapolations of animal results to man, unsuspected dynamical behavior of bilirubin molecules, etc. The story of its evolution up to present knowledge is reported in this paper.

    This study evaluates the exposure of newborn babies in neonatal intensive care units (NICU) to noise which can cause hearing lesions directly (acoustic trauma) as well as indirectly (hypoxia). Moreover, noise can have an aggravating effect when combined with other potentially harmful factors in the NICU, such as ototoxic medication or stress due to other external stimuli, such as excessively bright light, lack of a day/night rhythm or pain. Sound pressure levels were measured in the NICU and inside the cribs in various experimental conditions, classified under 3 different types of sound events: constant background noise, variations in background noise and impulsive events. The main sources of noise detected were crib noise generated by ventilation and temperature control systems, ambient noise in the room, noise caused by the staff in the NICU, noise generated by crib alarm systems and NICU apparatus and noise caused by activity on the crib cover or on its plexiglas top. Findings revealed that the influence of ambient noise is fairly irrelevant. Background noise and its variations concerned with activities in the department never exceeded the limits considered potentially harmful to adults (DRC), whereas the impulsive noise generated by staff on the cribs or on the plexiglas tops was considerable and potentially harmful. These findings demonstrate that it is feasible and relatively easy to control noise in the NICU and significantly reduce the impulsive noise component by training staff to be more careful and avoid any unnecessary jolting and rough handling on and near the cribs.

    Neonatal testicular torsion (NTT) is rare and reported salvage rates vary widely both in their cited frequency and plausibility. The timing and necessity of surgery is controversial with different centers arguing for the conservative management of all cases while others argue for prompt exploration for all. Confusion also reigns over the need to fix the contralateral testis. In order to clarify the issue the authors reviewed the literature and found 18 case series of NTT, containing 268 operated cases suitable for analysis. This paper reviews the literature on NTT specifically regarding salvage rates and timing/necessity of surgery. Its primary aim is to produce an overall salvage rate in the operated group. Overall salvage rate was 8.96%, 24 testes. When operation is specified as an emergency, salvage may be as high as 21.7%. While salvage of a testis torted at birth is rare, it is reported. Early asynchronous torsion is also rare but reported. Worryingly, bilateral torsion can present with unilateral signs.Given these findings, we would suggest early surgery with fixation of the contralateral side.

    Congential hemifacial spasm is a rare condition that is characterized by the occurrence of paroxysmal hemifacial contractions in neonates. We review the clinical, neurophysiological, neuroimaging, and histopathological findings, as well as the differential diagnosis, therapeutic approach, and outcome of all the described cases. Moreover, we report two new cases including the ictal video-electroencephalography recordings. Hemifacial spasm starts early in life, and is characterized by unilateral, involuntary, irregular tonic or clonic contractions of muscles innervated by the seventh cranial nerve. Hemifacial spasm is associated with eyelid blinking, and sometimes with breathing irregularities, hyperventilation, and/or other neurological manifestations (dystonic movements, nystagmus). Interictal and ictal video-electroencephalography did not reveal epileptiform abnormalities. In all cases, brain magnetic resonance imaging showed a mass involving the cerebellar peduncle, the cerebellar hemisphere, or the floor of the fourth ventricle. The semiology of the paroxysmal attacks is probably due to the activation of cranial nerve nuclei through intralesional hypersynchronous discharges, as shown by the intraoperative recordings and functional brain imaging described in the literature. We point out the importance of identifying such seizures in order to make an early diagnosis of the underlying cerebral lesion.

    Asphyxiating thoracic dystrophy is an autosomal recessive disorder characterised by an abnormally small thorax, variable shortening of the extremities, and pelvic anomalies. Renal and pancreatic symptoms are found in longer survivors, although most cases die in infancy of respiratory failure. Seven neonatal cases were studied at necropsy. These cases ranged in gestational age from 32 to 40 weeks. One was stillborn and the other six survived from 1 hour to 10 days. Two were sibs born to consanguineous parents. Dwarfing was not pronounced and the extremities were shortened in only one infant who also had polydactyly. All seven showed visceral changes in addition to abnormalities of bone. Endochondral ossification was irregular in sections of femur, vertebra, and rib. Pulmonary hypoplasia was associated with the small thorax typical of this disorder. Periportal fibrosis and bile duct proliferation were seen in sections of liver, and in one case cirrhosis was found. Pancreatic fibrosis was variable. These necropsy findings correlate with later clinical manifestations of the disease and emphasise the multisystem nature of this disorder. Images PMID:3989824

    Candida albicans has become an important cause of nosocomial infections in neonatal intensive care units (NICUs). The aim of the present study was to compare C. albicans strains isolated from neonates (NN) suffering from systemic candidosis and from nurses in order to determine the relatedness between NN and health workers' strains. Thirty-one C. albicans strains were isolated from 18 NN admitted to the NICU of the neonatology service of Farhat Hached Hospital of Sousse, Tunisia and suffering from systemic candidosis, together with five strains recovered from nurses suffering from C. albicans onychomycosis. Two additional strains were tested, one from an adult patient who developed a systemic candidosis and the second from an adult with inguinal intertrigo. All strains were karyotyped by pulsed-field gel electrophoresis (PFGE) with a CHEF-DR II system. Analysis of PFGE patterns yielded by the 38 strains tested led to the identification of three pulsotypes that were designated I, II and III, and consisted of six chromosomal bands with a size ranging from 700 to >2500 kbp. The most widespread was the pulsotype I, which was shared by 17 NN and the five nurses' strains. The identity between NN and nurses' strains is very suggestive of a nosocomial acquisition from health-workers.

    One of the most common causes of pain and disability in the upper limb is inflammation of the rotator cuff tendons. When no significant bony abnormality exists in the surrounding structures, the coracoacromial ligament has been implicated as a possible cause of impingement on the cuff tendons and various morphological variants of the ligament have so far been claimed to be either the cause or the result of impingement. In this study, 110 shoulders from 60 neonatal cadavers that were preserved in a preparation of formaldehyde were dissected. Anatomic variations of coracoacromial ligaments were investigated with metric and histologic analysis. Three main ligament types were identified: quadrangular, broad band and U-shaped. The multiple banded ligament was not found. Histologic analysis showed that in U-shaped ligaments a thin tissue existed in the central part of the ligament close to the coracoid. Comparing our data with the adult measurements of a previous study we suggest that the primordial ligament is broad shaped, but assumes a quadrangular shape due to the different growth rates of the coracoid and acromial ends. We also suggest that broad and U-shaped ligaments account for the primordial and quadrangular and Y-shaped ligaments account for the adult types of the single or double banded anatomic variants respectively. Our results show that various types of the coracoacromial ligament are present at the neonatal period and that the final shape of the ligament should be defined by developmental factors, rather than degenerative changes.

    Background The development of mucosal vaccines is crucial to efficiently control infectious agents for which mucosae are the primary site of entry. Major drawbacks of these protective strategies are the lack of effective mucosal adjuvant. Synthetic oligodeoxynucleotides that contain several unmethylated cytosine-guanine dinucleotide (CpG-ODN) motifs are now recognized as promising adjuvants displaying mucosal adjuvant activity through direct activation of TLR9-expressing cells. However, little is known about the efficacy of these molecules in stimulating the intestinal immune system in neonates. Methodology/Principal Findings First, newborn mice received CpG-ODN orally, and the intestinal cytokine and chemokine response was measured. We observed that oral administration of CpG-ODN induces CXC and CC chemokine responses and a cellular infiltration in the intestine of neonates as detected by immunohistochemistry. We next compared the efficiency of the oral route to intraperitoneal administration in stimulating the intestinal immune responses of both adults and neonates. Neonates were more responsive to TLR9-stimulation than adults whatever the CpG-ODN administration route. Their intestinal epithelial cells (IECs) indirectly responded to TLR9 stimulation and contributed to the CXC chemokine response, whereas other TLR9-bearing cells of the lamina-propria produced CC chemokines and Th1-type cytokines. Moreover, we showed that the intestine of adult exhibited a significantly higher level of IL10 at homeostasis than neonates, which might be responsible for the unresponsiveness to TLR9-stimulation, as confirmed by our findings in IL10-deficient mice. Conclusions/Significance This is the first report that deciphers the role played by CpG-ODN in the intestine of neonates. This work clearly demonstrates that an intraperitoneal administration of CpG-ODN is more efficient in neonates than in adults to stimulate an intestinal chemokine response due to their lower IL-10

    Background: A newborn is highly fragile whose death can be caused by embryonic, intrapartum, and postpartum factors. Identifying the causes of death is the first step to be taken in order to decrease the death rate. The present study was aimed at finding out how neonatal factors and therapeutic actions affect death of newborn babies. Materials and Methods: The is a case-control study where the case group included 250 dead neonates who were hospitalized in the neonatal intensive care unit during 2007-2009. The control group also included 250 newborn neonates who were hospitalized in the same unit and were discharged alive and healthy after they were treated appropriately. Researcher-designed questionnaires including demographic characteristics of mothers and infants, causes of hospitalization, treatment and its complications, and causes of death were used to collect the required data. Chi-square test, odds ratio (OR), and logistic regression were applied to analyze how the variables were related. P < 0.05 were considered significant. Statistical analyses were carried out using software SPSS 16.0. Results: The results of advanced logistic regression model showed that first-minute Apgar less than 6 (OR = 4.02), existence of birth asphyxia (OR = 6.16), hyaline membrane disease (OR = 4.08), and sepsis (OR = 6.42) increased the death rate of neonates hospitalized in the intensive care unit, and applying nasal continuous positive airway pressure and multiparity decreased the death rate of newborn babies. There was no significant correlation between variables such as low birth weight, consanguinity, blood group, pr eterm labor history, and baby's gender, and the death rate of neonates. Conclusions: The results of the study show that factors such as low Apgar score, asphyxia, hyaline membrane disease, sepsis, prematurity and congenital anomalies, and method of delivery have a positive effect on the death of neonates. They also prove that suitable management and carrying out

    Sex differences in brain neuroanatomy and neurophysiology underpin considerable physiological and behavioural differences between females and males. Sexual differentiation of the brain is regulated by testosterone secreted by the testes predominantly during embryogenesis in humans and the neonatal period in rodents. Despite huge advances in understanding how testosterone, and its metabolite oestradiol, sexually differentiate the brain, little is known about the mechanism that actually generates the male-specific neonatal testosterone surge. This review examines the evidence for the role of the hypothalamus, and particularly the gonadotropin-releasing hormone (GnRH) neurons, in generating the neonatal testosterone surge in rodents and primates. Kisspeptin-GPR54 signalling is well established as a potent and critical regulator of GnRH neuron activity during puberty and adulthood, and we argue here for an equally important role at birth in driving the male-specific neonatal testosterone surge in rodents. The presence of a male-specific population of preoptic area kisspeptin neurons that appear transiently in the perinatal period provide one possible source of kisspeptin drive to neonatal GnRH neurons in the mouse.

    Three experiments were conducted to investigate the effect of dosing corn oil on the colostrum consumption in neonatal piglets, the capacity of neonatal piglets to digest and absorb fish oil and the effect of fasting on that capacity, and the capacity of neonatal piglets to absorb and oxidize long chain and medium chain triacylglycerols to identify an appropriate source and dosage of fat for maximum amount of energy. In experiment 1, piglets were either dosed 8 ml corn oil per kg body weight or sham fed, and then the colostrum consumption of each piglet during next 24-h period was measured by an isotope dilution technique. In experiment 2, neonatal piglets were given an amount of fish oil calculated to provide the piglet's maintenance energy needs for 12 h. Twelve hours after administration of fish oil, contents of stomach, small intestine and large intestine and feces were collected for lipid analyses. In experiment 3, neonatal piglets were given one of three levels of either (1-/sup 14/C)-triolein or (1-/sup 14/C)-trioctanoin, which supplied about .5, 1.0 or 2.0 times piglet's maintenance energy needs for 12 h. The hourly /sup 14/CO/sub 2/ production was measured to estimate the oxidation rate, and the contents of digestive tract were collected for radioactivity and lipid analyses for estimating the absorption rate of the dosed triacylglycerols.

    This article provides a review of cerebral tissue oxygenation during immediate transition after birth in human neonates. Recommended routine monitoring, especially if resuscitation is needed, during this period includes arterial oxygen saturation and heart rate measured by pulse oximetry and electrocardiogram. However, there is increasing interest to monitor in addition with near-infrared spectroscopy (NIRS) the oxygenation of the brain. There is a different pattern of increase between cerebral tissue oxygenation and arterial oxygen saturation during the immediate transition, with cerebral tissue oxygenation reaching a plateau faster than arterial oxygen saturation. Differences can be explained, since cerebral tissue oxygenation is not only affected by arterial oxygen saturation but also by cerebral blood flow, hemoglobin content, and cerebral oxygen consumption. Normal values have already been established for different devices, gestational ages, and modes of delivery in neonates without any medical support. Cerebral hypoxia during immediate transition might cause brain damage. In preterm neonates with cerebral hemorrhage evolving in the first week after birth, the cerebral tissue oxygenation is already lower in the first minutes after birth compared to preterm neonates without cerebral hemorrhage. Using cerebral NIRS in combination with intervention guidelines has been shown to reduce the burden of cerebral hypoxia in preterm neonates. Cerebral tissue oxygenation during immediate transition seems to have an impact on outcome, whereby NIRS monitoring is feasible and has the advantage of continuous, non-invasive recording. The impact of NIRS monitoring and interventions on short- and long-term outcomes still need to be evaluated. PMID:28280719

    Purpose: The purpose of this study was to determine knowledge, attitude, and performance vis-à-vis pain management in neonates by nurses working in neonatal units in Bandar Abbas University hospitals. Method: This descriptive and analytical study was executed from March-August 2011 in the neonatal units and NICU in Bandar Abbas educational hospitals. A total of 50 nurses and nurse assistants working in the neonatal units participated in the study. The data collection tool was a structured questionnaire investigating knowledge (28 items), attitude (20 items) and practices (5 items). Data was analyzed using descriptive statistical tests (Frequency, Mean and Standard deviation tables) and inferential statistic (T-test, Variance analysis). Results: The knowledge scores of participants had a mean value of 13.51 (48.2%) out of 28. The mean score of attitude was 54.22 out of 60 and the mean score for the nurses’ level of practices was found to be 4.22 out of 10. There was a significant relationship between nurses’ knowledge scores and the level of education, i.e. nurses with more education had more knowledge. Conclusion: Results showed that the nurses had poor performance regarding the assessment, measurement, and relief of pain. However, they showed positive attitudes towards pain control in neonates.

    Sex differences in brain neuroanatomy and neurophysiology underpin considerable physiological and behavioural differences between females and males. Sexual differentiation of the brain is regulated by testosterone secreted by the testes predominantly during embryogenesis in humans and the neonatal period in rodents. Despite huge advances in understanding how testosterone, and its metabolite oestradiol, sexually differentiate the brain, little is known about the mechanism that actually generates the male-specific neonatal testosterone surge. This review examines the evidence for the role of the hypothalamus, and particularly the gonadotropin-releasing hormone (GnRH) neurons, in generating the neonatal testosterone surge in rodents and primates.

    Late-onset sepsis (LOS) in preterm neonates is increasingly reported to be associated with gut-colonizing Staphylococcus epidermidis. We aimed to describe the molecular epidemiology of S. epidermidis colonizing the gut of neonates hospitalized in two neonatal intensive care units. S. epidermidis from rectal swabs were typed by multilocus variable-number tandem-repeat analysis (MLVA), randomly chosen isolates of predominant MLVA types additionally by multilocus sequence typing. Antimicrobial susceptibility, the presence of icaA, IS256, arginine catabolic mobile element (ACME), agr type, and SCCmec type were determined. Of 276 neonates (38.4%), 106 were colonized with S. epidermidis, yielding a total of 139 isolates (62 in one unit and 77 in another unit). Of the 55 MLVA types identified, the five predominant detected in both units corresponded to sequence type (ST) 2, ST5, and ST59 or its single locus variant ST81 and formed three major MLVA clonal complexes accounting for 74.8% of all isolates. Overall, the prevalence of mecA, icaA, IS256, and ACME was 91.4%, 28.1%, 64%, and 77%, respectively. Of the mecA-positive isolates (n = 127), 43.9% carried SCCmec type IV. Of eight episodes of LOS, four were caused by ST2 and two by ST5. Preventing gut colonization with nosocomial epidemic S. epidermidis in hospitalized neonates could contribute to the prevention of LOS.

    Background and Objective: Vitamin D deficiency during pregnancy is a worldwide problem. Studies have reported prevalence ranged 18-84% in pregnant women. Receiving adequate calcium and vitamin D during pregnancy period is necessary for calcium homeostasis, fetal growth and bone mineralization. This study was aimed to determine the prevalence of vitamin D deficiency in pregnant women and their neonates in Shahroud city in the northeast Iran. Methods: In this cross-sectional study, 284 pregnant women and their neonates referred to Fatemiyeh Hospital of Shahroud were included. Blood samples of mothers and umbilical cords were collected during the delivery and were sent to laboratory in order to measure calcium and 25-hydroxy vitamin D. Findings: Amounts of Vitamin D insufficiency (20-30 ng/mL) and deficiency (<20 ng/mL) in (mothers, neonates) were found to be (60.2%, 48.9%) and (1.1%, 2.5%) respectively. Calcium deficiency (<8.5 mg/dL) was present in 33.5% of mothers and 25% of neonates. There was a weak correlation between maternal serum and cord blood 25-hydroxy vitamin D (r=0.12, p=0.053). Conclusion: More than half of the mothers and their neonates had some degrees of vitamin D deficiency. It is recommended to evaluate the nutritional status of vitamin D in pregnant women along with public health interventions to be carried out. PMID:27157170

    Diethylstilbestrol (DES), an endocrine-disrupting chemical, is an infamous artificial estrogenic compound. Although neonatal exposure to DES has been shown to result in inflammation of the male reproductive system, it has not, to our knowledge, been reported to induce testicular inflammation. Here we report that neonatal exposure to DES caused granulomatous orchitis with spermatogenic disturbance in 4 of 17 ICR male mice at 12 weeks of age. In the animals with spermatogenic disturbance, we observed either seminiferous tubules containing only cells with Sertoli cell features (likely Sertoli cell syndrome), or tubule cells in maturation arrest that contained only spermatogonia and/or spermatocytes. Following neonatal DES exposure, 5-week-old mice exhibited inflammation in cauda epididymis; by 8 weeks, the inflammation had spread to all segments of epididymis but not the testis; by 12 weeks, inflammation of the epididymis was observed in all mice. These data indicated that cauda epididymis has increased sensitivity to neonatal DES exposure compared to other segments of epididymis and testis. The data also implied that neonatal DES exposure-induced inflammation in cauda epididymis extended gradually to the testis via corpus and caput during development.

  20. Update on simulation for the Neonatal Resuscitation Program.

    The goal of the Neonatal Resuscitation Program is to have a trained provider in neonatal resuscitation at every delivery. The Neonatal Resuscitation Program develops its course content on review of the scientific evidence available for the resuscitation of newborns. Just as importantly, the educational structure and delivery of the course are based on evidence and educational theory. Thus, as simulation became a more accepted model in medical education and evidence was developing suggesting benefit of simulation, the Neonatal Resuscitation Program officially added simulation into its courses in 2010. Simulation-based medical education is now an integral part of the Neonatal Resuscitation Program courses both in teaching the psychomotor skills as well as the teamwork skills needed for effective newborn resuscitations. While there is evidence, as in other fields, suggesting that simulation for teaching newborn resuscitation is beneficial whether using high- or low-technology manikins or video-assisted debriefing or not, there are still many unanswered questions as to best practice and patient outcome effects.

  1. Neonatal euthanasia is unsupportable: the Groningen protocol should be abandoned.

    PubMed

    Kon, Alexander A

    2007-01-01

    The growing support for voluntary active euthanasia (VAE) is evident in the recently approved Dutch Law on Termination of Life on Request. Indeed, the debate over legalized VAE has increased in European countries, the United States, and many other nations over the last several years. The proponents of VAE argue that when a patient judges that the burdens of living outweigh the benefits, euthanasia can be justified. If some adults suffer to such an extent that VAE is justified, then one may conclude that some children suffer to this extent as well. In an attempt to alleviate the suffering of extremely ill neonates, the University Medical Center Groningen developed a protocol for neonatal euthanasia. In this article, I first present the ethical justifications for VAE and discuss how these arguments relate to euthanizing ill neonates. I then argue that, even if one accepts the justification for VAE in adults, neonatal euthanasia cannot be supported, primarily because physicians and parents can never accurately assess the suffering of children. I argue that without the testament of the patient herself as to the nature and magnitude of her suffering, physicians can never accurately weigh the benefits and burdens of a child's life, and therefore any such system would condemn to death some children whose suffering is not unbearable. I conclude that because the primary duty of physicians is to never harm their patients, neonatal euthanasia cannot be supported.

    Technologies for automated detection of neonatal seizures are gradually moving towards cot-side implementation. The aim of this paper is to present different ways to visualize the output of a neonatal seizure detection system and analyse their influence on performance in a clinical environment. Three different ways to visualize the detector output are considered: a binary output, a probabilistic trace, and a spatio-temporal colormap of seizure observability. As an alternative to visual aids, audified neonatal EEG is also considered. Additionally, a survey on the usefulness and accuracy of the presented methods has been performed among clinical personnel. The main advantages and disadvantages of the presented methods are discussed. The connection between information visualization and different methods to compute conventional metrics is established. The results of the visualization methods along with the system validation results indicate that the developed neonatal seizure detector with its current level of performance would unambiguously be of benefit to clinicians as a decision support system. The results of the survey suggest that a suitable way to visualize the output of neonatal seizure detection systems in a clinical environment is a combination of a binary output and a probabilistic trace. The main healthcare benefits of the tool are outlined. The decision support system with the chosen visualization interface is currently undergoing pre-market European multi-centre clinical investigation to support its regulatory approval and clinical adoption.

    The characteristics of high frequency (1000 Hz) acoustic admittance results obtained from normal neonates were described in this study. Participants were 170 healthy neonates (96 boys and 74 girls) aged between 1 and 6 days (mean = 3.26 days, SD = 0.92). Transient evoked otoacoustic emissions (TEOAEs), and 226 Hz and 1000 Hz probe tone tympanograms were obtained from the participants using a Madsen Capella OAE/middle ear analyser. The results showed that of the 170 neonates, 34 were not successfully tested in both ears, 14 failed the TEOAE screen in one or both ears, and 122 (70 boys, 52 girls) passed the TEOAE screen in both ears and also maintained an acceptable probe seal during tympanometry. The 1000 Hz tympanometric data for the 122 neonates (244 ears) showed a single-peaked tympanogram in 225 ears (92.2%), a flat-sloping tympanogram in 14 ears (5.7%), a double-peaked tympanogram in 3 ears (1.2%) and other unusual shapes in 2 ears (0.8%). There was a significant ear effect, with right ears showing significantly higher mean peak compensated static admittance and tympanometric width, but lower mean acoustic admittance at +200 daPa and gradient than left ears. No significant gender effects or its interaction with ear were found. The normative tympanometric data derived from this cohort may serve as a guide for detecting middle ear dysfunction in neonates.

  5. Domoic acid is a potent neurotoxin to neonatal rats.

    Domoic acid induces a time-dependent neuroexcitotoxic effect in neonatal rats characterized by hyperactivity, stereotypic scratching, convulsions, and death with observable behaviors occurring at exposures 40 times lower by body weight in neonates than reported in adults. Low doses of domoic acid (0.1 mg/kg) induced c-fos in the central nervous system which was inhibited in part by 2-amino-5-phosphonovaleric acid, an NMDA receptor antagonist. Domoic acid caused no evidence of structural alteration in the brain of neonates as assessed by Nissel staining and cupric silver histochemistry. Domoic acid induced reproducible behavioral effects at doses as low as 0.05 mg/kg and induced seizures doses as low as 0.2 mg/kg. Determination of serum domoic acid levels after 60 min exposure indicated that serum levels of domoic acid in the neonates corresponded closely to the serum levels that induce similar symptoms in adult rats and mice. We conclude that neonatal rats are highly sensitive to the neuroexcitatory and lethal effects of domoic acid and that the increased sensitivity results from higher than expected serum levels of domoic acid. These findings are consistent with other findings that reduced serum clearance of domoic acid is a predisposing factor to domoic acid toxicity.

    Neonatal sepsis causes a huge burden of morbidity and mortality and includes bloodstream, urine, cerebrospinal, peritoneal, and lung infections as well as infections starting from burns and wounds, or from any other usually sterile sites. It is associated with cytokine - and biomediator-induced disorders of respiratory, hemodynamic, and metabolic processes. Neonates in the neonatal intensive care unit feature many specific risk factors for bacterial and fungal sepsis. Loss of gut commensals such as Bifidobacteria and Lactobacilli spp., as occurs with prolonged antibiotic treatments, delayed enteral feeding, or nursing in incubators, translates into proliferation of pathogenic microflora and abnormal gut colonization. Prompt diagnosis and effective treatment do not protect septic neonates form the risk of late neurodevelopmental impairment in the survivors. Thus prevention of bacterial and fungal infection is crucial in these settings of unique patients. In this view, improving neonatal management is a key step, and this includes promotion of breast-feeding and hygiene measures, adoption of a cautious central venous catheter policy, enhancement of the enteric microbiota composition with the supplementation of probiotics, and medical stewardship concerning H2 blockers with restriction of their use. Additional measures may include the use of lactoferrin, fluconazole, and nystatin and specific measures to prevent ventilator associated pneumonia.

    Phototherapy has been the therapy of choice for the newborn with indirect hyperbilirubinemia. Intensive phototherapy requires a spectral irradiance of 30 microw/ cm2/nm, delivered over as much of the body surface as possible and is nowadays recommended for cases of neonatal hyperbilirubinemia with elevated total serum bilirubin (TSB) levels according to the guidelines. This study was conducted on neonates presenting to the out-born Neonatal Intensive Care Unit (NICU) of Cairo University Hospital with severe and extreme neonatal unconjugated hyperbilirubinemia during a 6 month period from August 2011 to January 2012. A total of 212 neonates presented with TSB > or = 20 mg/dl and were admitted for intensive phototherapy. The mean TSB on admission for all the cases was 26.8 +/- 6.2 mg/dl, ranging from 20 to 44 mg/dl. The mean duration of intensive phototherapy use was 14 hr. The mean rate of TSB declined during stay in the bilisphere was 1.019 mg/dl/hr. Exchange blood transfusion was indicated in 13 cases with extreme hyperbilirubinemia. 31 cases (14.62%) had rebound hyperbilirubinemia after phototherapy removal.

    Objective To determine the balance of metabolism of free bisphenol A (BPA) to the inactive conjugate, BPA glucuronide, in neonates. Study design Free BPA and BPA glucuronide concentrations were measured in 78 urine samples collected between December 2012 and August 2013 from a cohort of 44 healthy full term (≥ 37 weeks’ gestation) neonates at two intervals (3 - 6 days and 7 - 27 days of age). A questionnaire was administered at the time of sample collection. Neonates recruited into the study were born in an urban, tertiary care hospital. Results Only BPA glucuronide was detected in the urine samples; concentrations ranged from <0.1 μg/L to 11.21 μg/L (median: 0.27 μg/L). Free BPA concentrations were below the limit of quantification of 0.1 μg/L. Age, but not sex or type of diet was significantly associated with urinary BPA glucuronide concentration (p=0.002). Conclusions Our results illustrate widespread BPA exposure in healthy full-term neonates and efficient conjugation of BPA to its readily excretable and biologically inactive form (BPA glucuronide) as early as 3 days of age. Factors other than type of diet may be important contributors to BPA exposure in neonates. PMID:25921439

    This study evaluated etiologic and risk factors affecting long-term prognoses of neurologic outcomes in newborns with neonatal seizures. We enrolled patients at chronologic ages of 23-44 months, referred to the Department of Pediatric Neurology, Istanbul Medical Faculty, from January 1, 2007-December 31, 2009, after manifesting seizures in their first postnatal 28 days. Of 112 newborns, 41 were female, 71 were male, 33 were preterm, and 79 were full-term. Perinatal asphyxia (28.6%) and intracranial hemorrhage (17%) were the most common causes of neonatal seizures. Cerebral palsy developed in 27.6% of patients during follow-up. The incidence of epilepsy was 35.7%. Almost 50% of patients manifested developmental delay in one or more areas. Global developmental delay was the most common (50.8%) neurologic disorder. The correlation between gestational age or birth weight and adverse outcomes was nonsignificant. Etiology, Apgar score, need for resuscitation at birth, background electroencephalogram, neonatal status epilepticus, cranial imaging findings, type/duration of antiepileptic treatment, and response to acute treatment were all strong prognostic factors in neurologic outcomes. Neonatal seizures pose a threat of neurologic sequelae for preterm and full-term infants. Although the number of recognized etiologic factors in neonatal seizures has increased because of improvements in neonatology and diagnostic methods, perinatal asphyxia remains the most common factor.

    Predicting immediate neonatal morbidity after perinatal asphyxia has been difficult. A review of asphyxiated neonates greater than or equal to 36 weeks' gestation admitted to The Children's Hospital Newborn Intensive Care Unit in 1983 was conducted to devise a scoring system that would rapidly predict organ dysfunction observed in the immediate neonatal period. Comparison of potential score components to morbidity by multiple regression analysis yielded significant association with abnormalities in fetal heart rate monitoring, the 5-minute Apgar score, and neonatal base deficit. A scoring system was devised whose sensitivity (93.8%) and specificity (81.3%) were more predictive than any of its individual components. Prospective analysis in a similar population in 1984 validated its ability to distinguish severe from moderate morbidity after asphyxia. Positive predictive value for the score in the combined study groups (n = 98) was 79% and the negative predictive value was 83%. The scoring system may offer a rapid and accurate prediction of organ dysfunction in the immediate neonatal period after asphyxia.

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis.

However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis.

    Intrauterine or fetal growth restriction is best defined by using customised birth weight percentiles based upon the growth potential for an individual infant. Growth restriction in utero may be classified as asymmetric or symmetric depending upon the duration of the process. Asymmetric growth restriction is caused by placental insufficiency, maternal hypertensive conditions, long-standing maternal diabetes, smoking, living at altitude or multiple gestation. Symmetric growth restriction may be due to congenital infections, chromosomal or other abnormalities, fetal alcohol syndrome, low socioeconomic status or be constitutional. The underlying cause of growth restriction often predicts the potential adverse effects on the foetus and newborn and later effects in childhood and adulthood. With placental insufficiency, there may be chronic or acute on chronic fetal hypoxia with birth asphyxia and hypothermia, neonatal hypoglycaemia, polycythaemia and coagulopathy. Management is directed at prevention or early treatment of these conditions. In contrast, symmetrically growth-restricted infants should be examined carefully to look for congenital infections and malformations that may need specific interventions. Infants with constitutional short stature generally do not need any specific management. Feeding of growth-restricted infants is important to overcome deficiencies incurred in utero. Most infants show catch-up growth although about 10% do not. Those with excessive catch-up growth may be at greatest risk of developing insulin resistance in adulthood leading to diabetes, obesity and heart disease. The so-called fetal origins of disease may actually have a postnatal onset related more to excessive weight gain in infancy. There is still controversy over the indications for growth hormone treatment in growth-restricted infants who remain of short stature in early childhood. Intrauterine growth restriction is also associated with a five- to seven-fold increased risk of

    This article reviews the central role of nutrition in advancing the maternal, newborn, and child health agenda with a focus on evidence for effective interventions generated using randomized controlled trials in low- and middle-income countries (LMIC). The 1000 days spanning from conception to 2 years of life are a critical period of time when nutritional needs must be ensured; failure to do so can lead to adverse impacts on short-term survival as well as long-term health and development [corrected]. The burden of maternal mortality continues to be high in many under-resourced settings; prenatal calcium supplementation in populations with low intakes can reduce the risk of pre-eclampsia and eclampsia morbidity and mortality and is recommended, and antenatal iron-folic acid use in many countries may reduce anemia, a condition that may be an underlying factor in postpartum hemorrhage. Sufficient evidence exists to promote multiple micronutrient supplementation during pregnancy to reduce fetal growth restriction and low birth weight. Early initiation of breastfeeding (within an hour), exclusive breastfeeding in the first 6 months of life, and vitamin A supplementation in the first few days of life in Asia (but not in Africa) reduce infant mortality. Biannual large-dose vitamin A supplements to children 6-59 months of age and zinc for treatment of diarrhea continue to be important strategies for improving child health and survival. Early nutrition and micronutrient status can influence child development but should be integrated with early responsive learning interventions. Future research is needed that goes beyond the 1000 days to ensure adequate preconceptional nutrition and health, with special emphasis on adolescents who contribute to a large proportion of first births in many LMIC. Thus, we make the case for integrating proven nutrition interventions with those for health in pregnant women, and with those for health and child development in neonates, infants, and

    The purpose of this report is to compare the neonatal indices and the frequency of neonatal pathology in children, born after in vitro fertilization with those after natural conception. The study, which is a retrospective one, comprises all newborns from the three maternity hospitals of Pleven (University hospital, Saint Marina Obstetrical clinic, Avis-Medica Hospital) for the last 2 years. The comparative indices of the babies in the two groups are: birth weight and gestation age at birth, morbidity by separate nosological units: asphyxia, intraamniotic infection, intrauterine growth retardation, neonatal respiratory distress syndrome, congenital anomalies etc.), multiple births. The maternity age, delivery pattern, mean hospital stay and mortality are discussed too. The results are compared with other international data.

    The aim of this paper is to use recent advances in the clinical understanding of the temporal evolution of seizure burden in neonates with hypoxic ischemic encephalopathy to improve the performance of automated detection algorithms. Probabilistic weights are designed from temporal locations of neonatal seizure events relative to time of birth. These weights are obtained by fitting a skew-normal distribution to the temporal seizure density and introduced into the probabilistic framework of the previously developed neonatal seizure detector. The results are validated on the largest available clinical dataset, comprising 816.7 h. By exploiting these priors, the receiver operating characteristic area is increased by 23% (relative) reaching 96.74%. The number of false detections per hour is decreased from 0.45 to 0.25, while maintaining the correct detection of seizure burden at 70%.

  20. Fetal and neonatal alloimmune thrombocytopenia: progress and ongoing debates.

    PubMed

    Bussel, James B; Primiani, Andrea

    2008-01-01

    Fetal and neonatal alloimmune thrombocytopenia (AIT) is a result of a parental incompatibility of platelet-specific antigens and the transplacental passage of maternal alloantibodies against the platelet antigen shared by the father and the fetus. It occurs in approximately 1 in 1000 live births and is the most common cause of severe thrombocytopenia in fetuses and term neonates. As screening programs are not routinely performed, most affected fetuses are identified after birth when neonatal thrombocytopenia is recognized. In severe cases, the affected fetus is identified as a result of suffering from an in utero intracranial hemorrhage. Once diagnosed, AIT must be treated antenatally as the disease can be more severe in subsequent pregnancies. While there have been many advances regarding the diagnosis and treatment of AIT, it is still difficult to predict the severity of disease and which therapy will be effective.

    CME EDUCATIONAL OBJECTIVES: 1.Describe the varying clinical presentations of pseudohypoaldosteronism in the neonatal period.2.Review the physiology of aldosterone production and pathophysiology of pseudohypoaldosteronism.3.Identify treatment options for pseudohypoaldosteronism when identified in the neonatal period. Pseudohypoaldosteronism type I (PHA1) is a rare disease of mineralocorticoid resistance caused by defects in sodium transport in the distal tubule of the kidney. It presents in the neonate with life-threatening dehydration due to salt wasting, accompanied by hyperkalemia, acidosis, and, frequently, failure to thrive. Patients with PHA1 are often initially diagnosed with congenital adrenal hyperplasia, but their electrolyte abnormalities are resistant to treatment with glucocorticoids and mineralocorticoids. In these patients, an astute clinician will broaden his or her differential, resulting in life-saving treatment.

    This review summarizes the results of a study on rotaviruses isolated from calves affected by neonatal diarrhea. The results indicated that rotavirus infection is widespread and supported the evidence for an etiologic role of these viruses in neonatal diarrhea. Differences in virulence among bovine rotaviruses appeared also to be confirmed. Conventionally reared calves were fully susceptible to the experimental infection induced by rotaviruses originating from heterologous hosts, i.e. monkeys, pigs and rabbits. When rotavirus strains of bovine, simian and rabbit origin were compared by cross neutralization tests, it was found the simian and porcine strains were indistinguishable and both appeared to relate antigenically to the bovine strain. Finally, it was proven that feeding newborn calves with colostrum and first milk of their dams, previously vaccinated with an inactivated adjuvanted rotavirus vaccine, could prevent the neonatal diarrhea from occurring.

    Despite the fact that universal immunization against pertussis led to a dramatic decrease in the incidence and mortality in high-income countries, it has left a window of vulnerability for newborns. Although specific guidelines concerning management of neonatal whooping cough have not yet been developed, the present review summarizes the main available recommendations on diagnostic work-up and treatment of neonatal pertussis. Additionally, new prevention strategies are explored, including the use of an additional booster dose of vaccine to adolescents and adults, vaccination of healthcare workers, immunization of household contacts and caregivers (cocooning strategy), vaccination of pregnant women and, finally, neonatal immunization with novel vaccines. These strategies are analyzed and discussed in terms of efficacy, safety and cost-effectiveness.

    The inherited bone marrow failure syndromes (IBMFS) are a rare yet clinically important cause of neonatal hematological and non-hematological manifestations. Many of these syndromes, such as Fanconi anemia, dyskeratosis congenita and Diamond-Blackfan anemia, confer risks of multiple medical complications later in life, including an increased risk of cancer. Some IBMFS may present with cytopenias in the neonatal period whereas others may present only with congenital physical abnormalities and progress to pancytopenia later in life. A thorough family history and detailed physical examination are integral to the work-up of any neonate in whom there is a high index of suspicion for an IBMFS. Correct detection and diagnosis of these disorders is important for appropriate long-term medical surveillance and counseling not only for the patient but also for appropriate genetic counselling of their families regarding recurrence risks in future children and generations.

    Determining the right dose for drugs used to treat neonates is critically important. Neonates have significant differences in physiology affecting drug absorption, distribution, metabolism, and elimination that makes extrapolating dosages from adults and older children inappropriate. In spite of recent legislative efforts requiring drug studies in this population, most drugs given to neonates remain insufficiently studied. Many ethical and logistical concerns make designing studies in this age group difficult. Fortunately, specialized analytical techniques, such as the use of dried blood spots, scavenged sampling, population pharmacokinetics analyses, and sparse sampling, have helped investigators better define doses that maximize efficacy and safety. Through the use of these methods, successful clinical trials have resulted in recent changes to drug dosing in this population. PMID:25268145

    Cranial sonography continues to hold an important place in neonatal care. Attributes favorable to sonography that make it almost indispensable for routine care of the newborn includes easy access, low cost, portability, lack of ionizing radiations and exemption from sedation or anaesthesia. Cranial sonography has highest impact in neonates suspected to have meningitis and its complications; perinatal ischemia particularly periventricular leukomalacia (PVL); hydrocephalus resulting from multitude of causes and hemorrhage. Not withstanding this, cranial sonography has yielded results for a repertoire of indications. Approach to cranial sonography involves knowledge of the normal developmental anatomy of brain parenchyma for correct interpretation. Correct technique, taking advantage of multiple sonographic windows and variable frequencies of the ultrasound probes allows a detailed and comprehensive examination of brain parenchyma. In this review, we discuss the technique, normal and variant anatomy as well as disease entities of neonatal cranial sonography. PMID:27195026

    Ovarian cysts are the most common abdominal cysts in female fetuses and newborn girls. Ultrasonography is the imaging technique of choice for diagnosing ovarian cysts because it makes it possible to differentiate them from other cystic lesions. Although most neonatal ovarian cysts regress in the first few months after birth, complications can occur during gestation or after birth. The manifestations of ovarian cysts on ultrasonography will depend on the complications. The management is controversial, although the current trend favors watchful waiting. We describe the different presentations of neonatal ovarian cysts with their complications and their patterns of findings on ultrasonography. We also discuss the differential diagnosis with other cystic abdominal lesions, and finally we discuss the therapeutic management of neonatal ovarian cysts.

    This work is about the problem of noise in neonatal incubators and in the environment in the neonatal intensive care units. Its main objective is to analyse the impact of noise in hospitals of Mendoza and La Rioja. Methodology: The measures were taken in different moments in front of higher or lower severity level in the working environment. It is shown that noise produces severe damages and changes in the behaviour and the psychological status of the new born babies. Results: The noise recorded inside the incubators and the neonatal intensive care units together have many components but the noise of motors, opening and closing of access gates have been considered the most important ones. Values above 60 db and and up to 120 db in some cases were recorded, so the need to train the health staff in order to manage the new born babies, the equipment and the instruments associated with them very carefully is revealed.

    Opioid use in pregnancy has increased dramatically over the past decade. Since prenatal opioid use is associated with numerous obstetrical and neonatal complications, this now has become a major public health problem. In particular, in utero opioid exposure can result in neonatal abstinence syndrome (NAS) which is a serious condition characterized by central nervous system hyperirritability and autonomic nervous system dysfunction. The present review seeks to define current practices regarding the approach to the pregnant mother and neonate with prenatal opiate exposure. Although the cornerstone of prenatal management of opioid dependence is opioid maintenance therapy, the ideal agent has yet to be definitively established. Pharmacologic management of NAS is also highly variable and may include an opioid, barbiturate, and/or α-agonist. Genetic factors appear to be associated with the incidence and severity of NAS. Establishing pharmacogenetic risk factors for the development of NAS has the potential for creating opportunities for "personalized genomic medicine" and novel, individualized therapeutic interventions.

    Achieving adequate lighting in neonatal intensive care units is a major challenge: in addition to the usual considerations of visual performance, cost, energy and aesthetics, there appear different biological needs of patients, health care providers and family members. Communicational aspects of light, its role as a facilitator of the visual function of doctors and nurses, and its effects on the newborn infant physiology and development were addressed in order to review the effects of light (natural and artificial) within neonatal care with a focus on development. The role of light in regulating the newborn infant circadian cycle in particular and the therapeutic use of light in general were also reviewed. For each aspect, practical recommendations were specified for a proper well-lit environment in neonatal intensive care units.

    Hematologic and hematopoietic responses were evaluated in beagle dogs following a single prenatal (35 days gestation) or neonatal (10 days postpartum) exposure to 1.5 Gy /sup 60/Co gamma radiation. Hematopoiesis was studied by the in vitro culture of bone marrow granulocyte-macrophage progenitors (CFU-GM). Prenatally irradiated dogs exhibited a progressive, significant reduction in CFU-GM which was accompanied by decreases in peripheral blood leukocytes up to 24 weeks of age. Dogs which were neonatally irradiated also demonstrated a significant reduction in CFU-GM which was accompanied by significant alterations in peripheral white and red blood cell parameters. This was transient, however, and these dogs showed partial recovery of CFU-GM and hematologic parameter by 24 weeks of age. The persistent CFU-GM deficit in prenatally irradiated dogs suggests a relatively greater sensitivity of fetal marrow as compared to neonatal bone marrow for long-term damage by ionizing radiation.

  13. Role of pore-forming toxins in neonatal sepsis.

    PubMed

    Sonnen, Andreas F-P; Henneke, Philipp

    2013-01-01

    Protein toxins are important virulence factors contributing to neonatal sepsis. The major pathogens of neonatal sepsis, group B Streptococci, Escherichia coli, Listeria monocytogenes, and Staphylococcus aureus, secrete toxins of different molecular nature, which are key for defining the disease. Amongst these toxins are pore-forming exotoxins that are expressed as soluble monomers prior to engagement of the target cell membrane with subsequent formation of an aqueous membrane pore. Membrane pore formation is not only a means for immediate lysis of the targeted cell but also a general mechanism that contributes to penetration of epithelial barriers and evasion of the immune system, thus creating survival niches for the pathogens. Pore-forming toxins, however, can also contribute to the induction of inflammation and hence to the manifestation of sepsis. Clearly, pore-forming toxins are not the sole factors that drive sepsis progression, but they often act in concert with other bacterial effectors, especially in the initial stages of neonatal sepsis manifestation.

    2016-02-01

    Type 1 herpes simplex virus (HSV-1) is very prevalent yet in rare circumstances can lead to fatal neonatal disease. Genital acquisition of type 2 HSV is the usual mode for neonatal herpes, but HSV-1 transmission by genital or extragenital means may result in greater mortality rates. A very rare scenario is presented in which the mode of transmission was likely through breast lesions. The lesions were seen by nurses as well as the lactation consultant and obstetrician in the hospital after delivery of the affected baby but not recognized as possibly being caused by herpes. The baby died 9 days after birth with hepatic failure and disseminated intravascular coagulation. Peripartum health care workers need to be aware of potential nongenital (including from the breast[s]) neonatal herpes acquisition, which can be lethal.

    Objective To determine whether training traditional birth attendants to manage several common perinatal conditions could reduce neonatal mortality in the setting of a resource poor country with limited access to healthcare. Design Prospective, cluster randomised and controlled effectiveness study. Setting Lufwanyama, an agrarian, poorly developed district located in the Copperbelt province, Zambia. All births carried out by study birth attendants occurred at mothers’ homes, in rural village settings. Participants 127 traditional birth attendants and mothers and their newborns (3559 infants delivered regardless of vital status) from Lufwanyama district. Interventions Using an unblinded design, birth attendants were cluster randomised to intervention or control groups. The intervention had two components: training in a modified version of the neonatal resuscitation protocol, and single dose amoxicillin coupled with facilitated referral of infants to a health centre. Control birth attendants continued their existing standard of care (basic obstetric skills and use of clean delivery kits). Main outcome measures The primary outcome was the proportion of liveborn infants who died by day 28 after birth, with rate ratios statistically adjusted for clustering. Secondary outcomes were mortality at different time points; and comparison of causes of death based on verbal autopsy data. Results Among 3497 deliveries with reliable information, mortality at day 28 after birth was 45% lower among liveborn infants delivered by intervention birth attendants than control birth attendants (rate ratio 0.55, 95% confidence interval 0.33 to 0.90). The greatest reductions in mortality were in the first 24 hours after birth: 7.8 deaths per 1000 live births for infants delivered by intervention birth attendants compared with 19.9 per 1000 for infants delivered by control birth attendants (0.40, 0.19 to 0.83).

    Aim: To define the prognostic value of Doppler ultrasonographic morphology of ductus venosus (DV) waveform on canine neonatal mortality. Materials and Methods: Fifty-four healthy pregnant bitches underwent fetal ultrasonographic assessment. The DV waveforms were classified as diphasic (dDVw) or triphasic (tDVw) and compared with neonatal mortality. Results: Ninety-three fetuses were evaluated. Twenty fetuses belonged to litters with neonatal mortality, in which tDVw was observed. Seven fetuses belonged to litters without neonatal mortality, in which tDVw was observed. Fifty-eight fetuses belonged to litters without neonatal mortality, in which only dDVw was observed. Eight fetuses belonged to litters with neonatal mortality, in which only dDVw was observed. The correlation between tDVw and neonatal mortality was statistically significant (odds ratio [OR], 20.7; p<0.0001). Considering only pregnancies with one or two fetuses with the same DV waveform: Two fetuses with tDVw belonged to litters with neonatal mortality; 1 foetus with tDVw belonged to litter without neonatal mortality and 26 fetuses showed dDVw without neonatal mortality. The correlation between tDVw and neonatal mortality even in litters up to two pups was statistically significant (OR, 88.3; p=0.01). Conclusion: Echo-Doppler assessment of DV is feasible in canine fetuses, and the presence tDVw seems to be related to neonatal mortality. PMID:27182129

    Objective The objective of this study was to describe the incidence of baseline change within normal range during labor and its prediction of neonatal outcomes. Materials and Methods This was a prospective cohort of singleton, nonanomalous, term neonates with continuous electronic fetal monitoring and normal baseline fetal heart rate throughout the last 2 hours of labor. We determined baseline in 10-minute segments using Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria. We evaluated baseline changes of ≥ 20 and ≥ 30 bpm for association with acidemia (umbilical cord arterial pH ≤ 7.10) and neonatal intensive care unit (NICU) admission. Finally, we performed a sensitivity analysis of normal neonates, excluding those with acidemia, NICU admission, or 5-minute Apgar < 4. Results Among all neonates (n = 3,021), 1,267 (41.9%) had change ≥ 20 bpm; 272 (9.0%) had ≥ 30 bpm. Among normal neonates (n = 2,939), 1,221 (41.5%) had change ≥20 bpm. Acidemia was not associated with baseline change of any direction or magnitude. NICU admission was associated with decrease ≥ 20 bpm (adjusted odds ratio [aOR]: 2.93; 95% confidence interval [CI]: 1.19 - 7.21) or any direction ≥ 20 bpm (aOR: 4.06; 95% CI: 1.46-11.29). For decrease ≥ 20 bpm, sensitivity and specificity were 40.0 and 81.7%; for any direction ≥ 20 bpm, 75.0 and 58.3%. Conclusion Changes of normal baseline are common in term labor and poorly predict morbidity, regardless of direction or magnitude.

    To date, up to 65% of drugs used in neonates and infants are off-label or unlicensed, as they were implemented in clinical care without the usual regulatory phases of pharmacological drug development. Pharmacotherapy in this age group is still mainly based on the individual clinical expertise of specialized pediatricians. Pharmacological trials involving neonates are indeed more difficult to perform: appropriate dosing is hampered by the rapid physiological changes occurring at this stage of development, and the selection of proper end-points and biomarkers is complicated by the limited knowledge of the pathophysiology of the specific diseases of infancy. Moreover, there are many ethical challenges in planning and conducting drug studies in pediatric patients (especially in newborns and infants). In the current review, we address some challenges and discuss possible perspectives to stimulate scientific and clinical pharmacological research in neonates and infants. We hereby aim to illustrate the add on value of the regulatory framework for model-based neonatal medicinal development currently used in Europe and the United States. We provide several examples of successful recent pharmacological trials performed in neonates and infants. In these examples, success was ensured by the implementation of specific pharmacokinetic assessments, thanks to accurate drug dosing achieved with a combination of dose validation, population pharmacokinetics and mathematical models of drug clearance and distribution; moreover, age-specific pharmacodynamics was considered via appropriate evaluations of drug efficacy with end-points adapted to the peculiar pathophysiology of diseases in this age group. These "pharmacological" challenges add to the ethical challenges that are always present in planning and conducting clinical studies in neonates and infants and support the opinion that clinical research in pediatrics should be evaluated by ad hoc ethical committees with specific

    OBJECTIVE: To assist physicians in providing guidance to parents regarding neonatal circumcision. OPTIONS: Whether to recommend the routine circumcision of newborn male infants. OUTCOMES: Costs and complications of neonatal circumcision, the incidence of urinary tract infections, sexually transmitted diseases and cancer of the penis in circumcised and uncircumcised males, and of cervical cancer in their partners, and the costs of treating these diseases. EVIDENCE: The literature on circumcision was reviewed by the Fetus and Newborn Committee of the Canadian Paediatric Society. During extensive discussion at meetings of the committee over a 24-month period, the strength of the evidence was carefully weighed and the perspective of the committee developed. VALUES: The literature was assessed to determine whether neonatal circumcision improves the health of boys and men and is a cost-effective approach to preventing penile problems and associated urinary tract conditions. Religious and personal values were not included in the assessment. BENEFITS, HARMS AND COSTS: The effect of neonatal circumcision on the incidence of urinary tract infection, sexually transmitted diseases, cancer of the penis, cervical cancer and penile problems; the complications of circumcision; and estimates of the costs of neonatal circumcision and of the treatment of later penile conditions, urinary tract infections and complications of circumcision. RECOMMENDATION: Circumcision of newborns should not be routinely performed. VALIDATION: This recommendation is in keeping with previous statements on neonatal circumcision by the Canadian Paediatric Society and the American Academy of Pediatrics.

    Photoacoustic imaging (PAI) has been proposed as a non-invasive technique for the diagnosis and monitoring of disorders in the neonatal brain. However, PAI of the brain through the intact skull is challenging due to reflection and attenuation of photoacoustic pressure waves by the skull bone. The objective of this work was to develop a phantom for testing the potential limits the skull bone places on PAI of the neonatal brain. Our approach was to make acoustic measurements on materials designed to mimic the neonatal skull bone and construct a semi-realistic phantom. A water tank and two ultrasound transducers were utilized to measure the ultrasound insertion loss (100 kHz to 5MHz) of several materials. Cured mixtures of epoxy and titanium dioxide powder provided the closest acoustic match to neonatal skull bone. Specifically, a 1.4-mm thick sample composed of 50% (by mass) titanium dioxide powder and 50% epoxy was closest to neonatal skull bone in terms of acoustic insertion loss. A hemispherical skull phantom (1.4 mm skull thickness) was made by curing the epoxy/titanium dioxide powder mixture inside a mold. The mold was constructed using 3D prototyping techniques and was based on the hairless head of a realistic infant doll. The head was scanned to generate a 3D model, which in turn was used to build a 3D CAD version of the mold. The mold was CNC machined from two solid blocks of Teflon®. The neonatal skull phantom will enable the study of the propagation of photoacoustic pressure waves under a variety of experimental conditions.

    Objective To compare error rates of three existing methods of predicting the gastric tube insertion length in a group of neonates < one month corrected age: age-related, height-based (ARHB); direct distance nose-ear-xiphoid (NEX); and direct distance nose-ear-mid-umbilicus (NEMU). Design Randomized controlled trial. Setting Five neonatal care units in a large midwestern city. Participants One hundred seventy-three hospitalized neonates. Methods Neonates were randomly assigned to one of three groups: ARHB, NEX, or NEMU. For primary analysis, only tubes placed too high with the tube tip in the esophagus or at the gastroesophageal junction were considered to be misplaced. For secondary analysis, a stricter definition was used, and low placements (pylorus or duodenum) were also considered to be misplaced. All radiographs were blinded and read by a pediatric radiologist. Results For the primary analysis, the differences in percentages of correctly placed tubes among the three methods was statistically significant (chi-square = 34.45; p < 0.0001), with both NEMU and ARHB more accurate than NEX (NEMU chi-square = 18.59, p < 0.0001; ARHB chi-square = 21.34, p < 0.0001). Using the stricter definition for placement, ARHB was not significantly different from NEX (p = 0.0615). A new ARHB equation was developed specific for neonates < 1 month corrected age. Conclusions Direct distance nose-ear-xiphoid should no longer be used as an NG/OG tube insertion-length predictor in neonates. Either NEMU for nasogastric/orogastric (NG/OG) tubes or the new ARHB equation for NG tubes should be used. PMID:21639864

    Respiratory depression, the most serious side-effect of opioid treatment, is well documented for morphine, the most commonly used opioid in neonatal care. Less is known about methadone, a clinically relevant opioid analgesic, especially during neonatal development. This study was undertaken to determine the neonatal respiratory effects of methadone. We hypothesize that methadone is equipotent to morphine, compared to our previous morphine results in the same animal model, but has a much longer duration of action, due to its longer elimination half-life. Neonatal guinea pigs (3-14 days old) randomly received a single subcutaneous dose of methadone or saline. Using a non-invasive plethysmographic method, we measured ventilatory and metabolic parameters before injection and at intervals for 32 hr after injection while pups breathed "room air" or 5% CO(2) gas mixtures. Methadone-induced depression of ventilation was most evident during 5% CO(2) challenge. The onset of drug effects was within 15 min for all ages and doses, but the duration of action decreased with age. While the depth of methadone-induced respiratory depression did not depend on pup age, the control of breathing was different in 3-day-old pups, where inspiratory time increased fourfold; twice that of older pups. We conclude that methadone induces a naloxone reversible respiratory depression in guinea pig neonates and, in the very young, causes an abnormal breathing pattern due to changes in respiratory timing. Methadone is more potent than morphine with respect to neonatal respiratory depression, but surprisingly, the duration of methadone action was not longer than morphine.

    Neonatal rat ventricular myocytes (NRVM) and fibroblasts (FBs) serve as in vitro models for studying fundamental mechanisms underlying cardiac pathologies, as well as identifying potential therapeutic targets. Both cell types are relatively easy to culture as monolayers and can be manipulated using molecular and pharmacological tools. Because NRVM cease to proliferate after birth, and FBs undergo phenotypic changes and senescence after a few passages in tissue culture, primary cultures of both cell types are required for experiments. Below we describe methods that provide good cell yield and viability of primary cultures of NRVM and FBs from 0 to 3-day-old neonatal rat pups.

    The neonatal foal is in a transitional state from prenatal to postnatal circulation. Healthy newborn foals often have cardiac murmurs and dysrhythmias, which are usually transient and of little clinical significance. The neonatal foal is prone to infection and cardiac trauma. Echocardiography is the main tool used for valuation of the cardiovascular system. With prompt identification and appropriate action, dysrhythmias and other sequel to cardiac trauma can be corrected. With infection, the management and prognosis are driven by concurrent sepsis. Congenital disease represents an interesting diagnostic challenge for the neonatologist, but surgical correction is not appropriate for most equids.

    Background Neonatal Tuberose sclerosis complex may be associated with symptomatic cardiac rhabdomyomas. Cardiac rhabdomyomas are the most common cardiac tumours. The symptoms include haemodynamic instability and life threatening arrhythmias usually requiring early surgical intervention. Results We report a case of a 32 week gestation newborn diagnosed with a right ventricular outflow tract mass and subsequently diagnosed with tuberose sclerosis that needed early surgical intervention. Conclusion While this case needed early intervention, the need for surgical intervention in otherwise asymptomatic cases is debatable as neonatal cardiac rhabdomyomas can spontaneously regress.

    We have investigated the neuroexcitatory and neurodegenerative effects of brevetoxin on neonatal rats. Brevetoxin, a marine-biotoxin that has been implicated in several seafood poisoning incidents, is produced by the dinoflagellate Gymnodinium brevis. Four studies were done: dose response, northern analysis, immunohistochemistry and neurodegeneration. We found that neonatal rats are much more sensitive to brevetoxin than adult rats. The effectiveness of c-fos as a biomarker is being investigated, because of the high basal expression in young animals. The neurodegeneration, although not available yet, should provide valuable information.

    Nosocomial infections are responsible for significant morbidity and late mortality among neonatal intensive care unit patients. The number of neonatal patients at risk for acquiring nosocomial infections is increasing because of the improved survival of very low birthweight infants and their need for invasive monitoring and supportive care. Effective strategies to prevent nosocomial infection must include continuous monitoring and surveillance of infection rates and distribution of pathogens; strategic nursery design and staffing; emphasis on handwashing compliance; minimizing central venous catheter use and contamination, and prudent use of antimicrobial agents. Educational programs and feedback to nursery personnel improve compliance with infection control programs.

    Nociceptive neuronal circuits are formed during embryonic and postnatal times when painful stimuli are normally absent or limited. Today, medical procedures for neonates with health risks can involve tissue injury and pain for which the long-term effects are unknown. To investigate the impact of neonatal tissue injury and pain on development of nociceptive neuronal circuitry, we used an animal model of persistent hind paw peripheral inflammation. We found that, as adults, these animals exhibited spinal neuronal circuits with increased input and segmental changes in nociceptive primary afferent axons and altered responses to sensory stimulation.

    The level of contamination of stethoscopes used in a neonatal intensive care unit was studied, along with the practices used for cleaning these items. A policy of alcohol cleaning was introduced and the effect of this change on the level of bacterial growth was observed after a six-week period. It was found that 71% of stethoscopes had a significant bacterial growth and that this was reduced to 30% after the cleaning procedure change (P < 0.05). Stethoscopes and other equipment are a potential source of nosocomial infection on the neonatal intensive care unit.

    The clinical presentation of cute appendicitis is rarely encountered in neonatology. When it does occur, it is thought to be due to prematurity or develops secondary to coexisting diseases. We present a case of appendicitis in a 10-day-old Middle-Eastern girl, who was born at term and who had no underlying conditions that are typically associated with neonatal appendicitis. This case highlights that certain causes and clinical signs are unreliable when coming to a working diagnosis of neonatal appendicitis, and that regardless of the cause, timely detection and management are necessary in achieving surgical success.

    The emergence of the interdisciplinary field of salivary bioscience has created opportunity for neonatal researchers to measure multiple components of biological systems non-invasively in oral fluids. The implications are profound and potentially high impact. From a single oral fluid specimen, information can be obtained about a vast array of biological systems (e.g., endocrine, immune, autonomic nervous system) and the genetic polymorphisms related to individual differences in their function. The purpose of this review is to describe the state of the art for investigators interested in integrating these unique measurement tools into the current and next generation of research on gonadal steroid exposure during the prenatal and neonatal developmental periods.

    We describe a dysmature (small-for-gestational-age) neonate born at term with multiple congenital defects, who presented with bloody diarrhoea. The abdominal X-ray showed gastric pneumatosis. The patient was treated conservatively with intravenous fluids and antibiotics, and recovered uneventfully. The patient underwent genetic investigation, and was diagnosed with Cornelia de Lange syndrome. Gastric pneumatosis is rare, and may be the result of neonatal sepsis, gastritis, pyloric stenosis, necrotising enterocolitis of the stomach, misplacement of nasogastric tubes, or non-invasive positive pressure ventilation. Furthermore, it is speculated that gastric pneumatosis might more frequently occur with congenital, cardiac or genetic disorders.

    Skin-to-skin contact, or kangaroo care (KC), has benefits for babies and parents, improving clinical outcomes, temperature control, breastfeeding rates and child-parent bonding; it reduces morbidity and mortality. Barriers to KC for neonates may include a lack of training for nurses, lack of time, maternal or child physical or mental ill health, and inappropriate settings. With education and helpful management, neonatal nurses can advocate for KC for all babies. Parents may need information and encouragement to begin with. Therefore, nurses can improve the experiences of their patients and, in the long run, free time to perform clinical procedures.

    21,013 newborns were screened on the first year of a neonatal screening program on congenital hypothyroidism in the Basque Community. The evaluation of the results showed some points of interest. One of them, would be the high analytical retesting rate needed in the screening of very low-birth weight children. The rate decreased with increasing birth-weight. Forty per cent of the children with a birth-weight lower than 1,000 gr needed retesting. The rate decreased to 7.7% at birth-weights between 1,001 and 1,500 gr, to 2% at birth weights between 1,501 and 2,500 gr and only to 0,42% at birth-weights higher than 2,501 gr. The consequences of these results are discussed.
