    ABSTRACT: To describe the results of brain magnetic resonance imaging (MRI) of infants with bacterial meningitis and how the findings affected clinical management. This retrospective study included all infants <12 months of age who were hospitalized at Children's Medical Center, Dallas and had culture-confirmed bacterial meningitis and a brain MRI from January 1, 2001 to December 1, 2011. Infants were identified by review of all positive bacterial cultures of cerebrospinal fluid (CSF) from the Children's Medical Center Microbiology Laboratory. Demographic, clinical, laboratory, and neuroimaging data were reviewed. Infants with ventriculoperitoneal shunt or whose CSF culture yielded skin commensals were excluded. A neuroradiologist blinded to clinical information reviewed all MRI studies. Of the 440 infants who had a positive CSF culture result, 111 (25%) had a pathogen isolated from CSF and were enrolled in the study. Of these, 68% (75/111) had a brain MRI performed during the hospitalization; abnormalities included leptomeningeal enhancement (57%), cerebral infarct (43%), subdural empyema (52%), cerebritis (26%), hydrocephalus (20%), and abscess (11%). By multiple logistic regression analysis, infants with late seizures and an abnormal neurologic examination were more likely to have an abnormal MRI (P < .05). MRI results led to neurosurgical intervention in 23% of infants; a positive bacterial culture of CSF obtained >48 hours after initiation of antibiotic therapy was associated with neurosurgical intervention (P = .01). Fourteen (19%) infants with bacterial meningitis had a normal brain MRI. Brain MRIs were performed frequently and often were abnormal in infants with bacterial meningitis, leading to changes in clinical management.

    ABSTRACT: In 2012, pertussis outbreak in a Dallas county resulted in the deaths of 4 children (3, unvaccinated; 2, <60 days of age). Despite recommendations that include immunization of women preferably during the third trimester of pregnancy or postpartum, household contacts ("cocooning"), and infants as early as 42 days of age, challenges in pertussis prevention remain.

    ABSTRACT: Objective The objective of this study was to characterize the incidence, management, and short-term outcomes of cardiovascular insufficiency (CVI) in mechanically ventilated newborns, evaluating four separate prespecified definitions. Study Design Multicenter, prospective cohort study of infants ≥34 weeks gestational age (GA) and on mechanical ventilation during the first 72 hours. CVI was prospectively defined as either (1) mean arterial pressure (MAP) < GA; (2) MAP < GA + signs of inadequate perfusion; (3) any therapy for CVI; or (4) inotropic therapy. Short-term outcomes included death, days on ventilation, oxygen, and to full feedings and discharge. Results Of 647 who met inclusion criteria, 419 (65%) met ≥1 definition of CVI. Of these, 98% received fluid boluses, 36% inotropes, and 17% corticosteroids. Of treated infants, 46% did not have CVI as defined by a MAP < GA ± signs of inadequate perfusion. Inotropic therapy was associated with increased mortality (11.1 vs. 1.3%; p < 0.05). Conclusion More than half of the infants met at least one definition of CVI. However, almost half of the treated infants met none of the definitions. Inotropic therapy was associated with increased mortality. These findings can help guide the design of future studies of CVI in newborns.

    ABSTRACT: Objective Obstetric antecedents were analyzed in births where the infant received whole-body cooling for neonatal encephalopathy. Methods This retrospective cohort study included all live-born singleton infants delivered at or beyond 36 weeks gestation from October 2005 through December 2011. Infants who had received whole-body cooling identified by review of a prospective neonatal registry were compared to a control group comprising the remaining obstetric population delivered at greater than 36 weeks but not cooled. Univariable analysis was followed by a staged, stepwise selection of variables with the intent to rank significant risk factors for cooling. Results A total of 86,371 women delivered during the study period and 98 infants received whole-body cooling (1.1/1,000 livebirths). Of these 98 infants, 80 (88%) newborns had moderate encephalopathy and 10 (12%) had severe encephalopathy prior to cooling. Maternal age less than or equal to 15 years, low parity, maternal body habitus (BMI > 40 kg/m2), diabetes, preeclampsia, induction, epidural analgesia, chorioamnionitis, length of labor, and mode of delivery were associated with significantly increased risk of infant cooling during univariable analysis. Catastrophic events to include umbilical cord prolapse (OR 14; 95%CI, 3-72), placental abruption (OR 17; 95%CI, 7-44), uterine rupture (OR 130; 95%CI, 11-1477) were the strongest factors associated with infant cooling after staged-stepwise logistic analysis. Conclusion A variety of intrapartum characteristics were associated with infant cooling for neonatal encephalopathy with the most powerful antecedents being umbilical cord prolapse, placental abruption, and uterine rupture.

    ABSTRACT: Background MRI is a surrogate biomarker for major neurodevelopmental disabilities in survivors of perinatal hypoxic-ischemic encephalopathy as injury to the basal ganglia/thalami is highly predictive of major neuromotor and cognitive problems. Major disabilities and the appearance of neonatal (R2-2) MRI are improved with therapeutic hypothermia. We evaluated neurodevelopmental outcomes when conventional MRI showed minimal or no brain injury. Methods IRB-approved series of 62 infants (≥36 weeks; ≥1800 g; 34 male/28 female) cooled for hypoxic-ischemic encephalopathy from 2005-11 who underwent neonatal (R2-2) MRI and Bayley Scales of Infant and Toddler Development -III 22 +/- 7 (R2-9) months of age. MRI at 5-14 (mean 8) days was scored as normal (score=0), showing focal grey or white matter injury only (score =1), or basal ganglia/thalamic and/or watershed lesions with or without more extensive hemispheric injury (score =2). Sensitivity, specificity, and positive (PPV) and negative predictive values (NPV) for MR scores 0 and 1 and statistical interaction between MRI score and age at MRI were determined. Results MR score=0 was seen in 35/62 patients; 26/35 (74%) were typically developing, 7 (20%) had moderate and 2 (6%) had severe delay. MR score=1 was seen in 17/62 (27%) patients; 5/17 (29%) were normal, 11/17 (65%) had moderate delay, and 1/17 (6%) had severe neurodevelopmental delay. Of the 52 patients with MR scores 0 and 1, 40% were abnormal. The NPV of a normal MRI was 74%. For score 1, sensitivity was 95% [CI 63%-83%], specificity 84% [CI 70%-90%], PPV 84% [CI 71%-93%], and NPV 74% [CI 62%-82%]. Conclusions Caution is warranted when prognosticating about neurodevelopmental status in early childhood after HIE with cooling and longer follow-up studies are needed to determine the prognostic significanceof a neonatal MRI (R2-4) showing no or minor degrees of brain injury.

    ABSTRACT: To describe the clinical manifestations and short-term outcomes of adenoviral infections in neonates and review all published cases to better determine impact and treatment outcomes. Retrospective cohort study of all neonates hospitalized at Children's Medical Center (CMC) and Parkland Memorial Hospital (PMH), Dallas, TX with laboratory-confirmed adenoviral infection from January 1,1995-December 31, 2012. Neonates were identified by review of the CMC Virology Laboratory's prospective database of all positive adenovirus tests performed in the inpatient and ambulatory settings, and at PMH, of a prospective neonatal database that included all neonatal intensive care unit admissions. Patients also were identified by discharge International Classification of Disease, 9th edition codes for adenoviral infection. The medical records were reviewed, and a review of the English literature was performed. During 17 years, 26 neonates had adenoviral infection (25, CMC; 1, PMH). The principle reasons for hospitalization were respiratory signs (88%) and temperature instability (65%). Five (19%) had disseminated disease and 4 (80%) of these infants died. Ribavirin or cidofovir treatment, as well as immune globulin intravenous, did not improve outcomes except in 1 neonate. Literature review (n = 72) combined with our data found that disseminated infection was associated with death (68% vs 21% with localized infection, P < .001). In addition, neonates <14 days of age were more likely to have disseminated disease (44% vs 12%, P = .004) and death (48% vs 8%; P < .001). Adenoviral infection in hospitalized neonates was associated with severe morbidity and mortality, especially when infection was disseminated and involved the respiratory tract. Development of new therapeutic strategies is needed.

    ABSTRACT: To evaluate serum neuronal and inflammatory biomarkers to determine whether measurements of umbilical cords at birth can stratify severity of hypoxic-ischemic encephalopathy (HIE), whether serial measurements differ with hypothermia-rewarming, and whether biomarkers correlate with neurological outcomes. This is a prospective cohort of inborn term newborns with varying degrees of HIE by neurological assessment. Neuronal glial fibrillary acidic protein (GFAP), ubiquitin carboxyl-terminal hydrolase L1, and inflammatory cytokines were measured in serum from umbilical artery at 6-24, 48, 72, and 78 hours of age. Neurodevelopmental outcomes (Bayley Scales of Infant and Toddler Development-III scales) were performed at 15-18 months. Twenty neonates had moderate (n = 17) or severe (n = 3) HIE and received hypothermia; 7 had mild HIE and were not cooled. At birth, serum GFAP and ubiquitin carboxyl-terminal hydrolase L1 increased with the severity of HIE (P < .001), and serial GFAP remained elevated in neonates with moderate to severe HIE. Interleukin (IL)-6, IL-8, and vascular endothelial growth factor were greater at 6-24 hours in moderate to severe vs mild HIE (P < .05). The serial values were unaffected by hypothermia-rewarming. Elevated GFAP, IL-1, IL-6, IL-8, tumor necrosis factor, interferon, and vascular endothelial growth factor at 6-24 hours were associated with abnormal neurological outcomes. The severity of the hypoxic-ischemic injury can be stratified at birth because elevated neuronal biomarkers in cord serum correlated with severity of HIE and outcomes.

    ABSTRACT: OBJECTIVE:Parkland Memorial Hospital (PMH) participated in Surfactant, Positive Pressure, and Oxygenation Randomized Trial (SUPPORT), an unblinded controlled trial, in which preterm neonates of 24(0/7) to 27(6/7) weeks' gestational age (GA) were randomized in the delivery room (DR) to endotracheal intubation or nasal continuous positive airway pressure. We hypothesized that DR intubation could change in nonenrolled patients at PMH and that the change would be larger than in comparable centers not participating in the trial.METHODS:The PMH Cohort included eligible but nonenrolled neonates of 24(0/7) to 27(6/7) weeks (primary) and noneligible neonates of 28 to 34(6/7) weeks (confirmatory). A subset (24(0/7)-29(6/7)weeks) of that cohort was compared with a contemporaneous cohort born in centers participating in the Vermont Oxford Network (VON). We used a Poisson regression model to obtain adjusted relative risks (RRs) of DR intubation (during/after SUPPORT versus before SUPPORT) for PMH and for VON along with the ratio of these RRs.RESULTS:In the PMH cohort (n = 3527), the proportion of DR intubation decreased during/after SUPPORT in the lower GA group (adjusted RR 0.76, 95% confidence interval [CI] 0.59-0.96) and the upper GA group (adjusted RR 0.57, 95% CI 0.46-0.70). Compared with the RR for DR intubation in VON, the RR at PMH was smaller in the lower (ratio of RR 0.76, 95% CI 0.65-0.87) and the upper GA group (ratio of RR 0.52, 95% CI 0.39-0.68).CONCLUSIONS:A center's participation in an unblinded randomized trial may affect process of care of nonenrolled patients.

    ABSTRACT: Background:Myo-inositol given to preterm infants with respiratory distress has reduced death, increased survival without bronchopulmonary dysplasia, and reduced severe retinopathy of prematurity in two randomized trials. Pharmacokinetic (PK) studies in extremely preterm infants are needed before efficacy trials.Methods:Infants born in 23-29 wk of gestation were randomized to a single intravenous (i.v.) dose of inositol at 60 or 120 mg/kg or placebo. Over 96 h, serum levels (sparse sampling population PK) and urine inositol excretion were determined. Population PK models were fit using a nonlinear mixed-effects approach. Safety outcomes were recorded.Results:A single-compartment model that included factors for endogenous inositol production, allometric size based on weight, gestational age strata, and creatinine clearance fit the data best. The central volume of distribution was 0.5115 l/kg, the clearance was 0.0679 l/kg/h, endogenous production was 2.67 mg/kg/h, and the half-life was 5.22 h when modeled without the covariates. During the first 12 h, renal inositol excretion quadrupled in the 120 mg/kg group, returning to near-baseline value after 48 h. There was no diuretic side effect. No significant differences in adverse events occurred among the three groups (P > 0.05).Conclusion:A single-compartment model accounting for endogenous production satisfactorily described the PK of i.v. inositol.Pediatric Research (2013); doi:10.1038/pr.2013.162.

    ABSTRACT: OBJECTIVE:Preterm infants are at increased risk of severe rotavirus gastroenteritis. Although immunization with rotavirus vaccine is safe and effective, age restrictions limit the number of infants eligible for vaccination at discharge from the NICU. The objectives of this study were to assess the implementation of the rotavirus vaccine program in our NICU, recognize missed opportunities for vaccination, and document how often very low birth weight (VLBW; birth weight ≤1500 g) and extremely low birth weight (ELBW; birth weight <1000 g) infants were eligible to receive rotavirus vaccine at the time of NICU discharge.METHODS:This study reports on a prospective, observational cohort of all VLBW infants who were discharged from the NICU at Parkland Memorial Hospital from May 2008 to April 2010. Medical records were reviewed and data collected regarding the number of infants who were eligible for and received rotavirus vaccination at discharge.RESULTS:A total of 63% (135 of 213) of VLBW infants did not receive rotavirus vaccine. The reasons for not providing vaccine included the following: <42 days of age at discharge (56 of 213; 26%), >84 or 104 days of age at discharge (48 of 213; 23%), or missed (35 of 213; 16%). The majority (75%) who were too old for vaccination at the time of discharge were ELBW.CONCLUSIONS:The current age restrictions for rotavirus immunization resulted in more than half of ELBW infants being ineligible for vaccination at the time of discharge from the NICU. Alternative strategies for rotavirus immunization in this population are needed.

    ABSTRACT: Bone lesions on radiographs of newborns often suggest congenital infections. Skeletal roentgenograms are recommended in the evaluation of suspected congenital syphilis, but bone lesions have been recognized in other congenital infections. We report the case of an infant with hydrops fetalis secondary to congenital parvovirus B19 infection who was found to have bone lesions in multiple long and axial bones on admission to the neonatal ICU. Both the infant and her mother were evaluated for other causes of congenital infection, but no other agents were identified. The bone lesions had nearly completely resolved by 10 weeks of age. Screening of neonates with congenital parvovirus B19 infection for bone lesions may provide additional insight into the incidence and pathophysiology of these lesions.

    ABSTRACT: OBJECTIVES: To assess the effectiveness of a set of multidisciplinary interventions aimed at limiting patient-to-patient transmission of extended-spectrum β-lactamase-producing Klebsiella pneumoniae (ESBL-KP) during a neonatal intensive care unit (NICU) outbreak, and to identify risk factors associated with ESBL-KP colonization and disease in this setting. STUDY DESIGN: A 61-infant cohort present in the NICU during an outbreak of ESBL-KP from April 26, 2011, to May 16, 2011, was studied. Clinical characteristics were compared in infected/colonized infants and unaffected infants. A multidisciplinary team formulated an outbreak control plan that included (1) staff reeducation on recommended infection prevention measures; (2) auditing of hand hygiene and environmental services practices; (3) contact precautions; (4) cohorting of infants and staff; (5) alleviation of overcrowding; and (6) frequent NICU-wide screening cultures. Neither closure of the NICU nor culturing of health care personnel was instituted. RESULTS: Eleven infants in this level III NICU were infected/colonized with ESBL-KP. The index case was an 18-day-old infant born at 25 weeks' gestation who developed septicemia from ESBL-KP. Two other infants in the same room developed sepsis from ESBL-KP within 48 hours; both expired. Implementation of various infection prevention strategies resulted in prompt control of the outbreak within 3 weeks. The ESBL-KP isolates presented a single clone that was distinct from ESBL-KP identified previously in other units. Being housed in the same room as the index infant was the only risk factor identified by logistic regression analysis (P = .002). CONCLUSION: This outbreak of ESBL-KP affected 11 infants and was associated with 2 deaths. Prompt control with eradication of the infecting strain from the NICU was achieved with multidisciplinary interventions based on standard infection prevention practices.

    ABSTRACT: OBJECTIVE: To examine whether preterm very low birth weight (VLBW) infants have an increased risk of late-onset sepsis (LOS) following early-onset sepsis (EOS). STUDY DESIGN: Retrospective analysis of VLBW infants (401-1500 g) born September 1998 through December 2009 who survived >72 hours and were cared for within the National Institute of Child Health and Human Development Neonatal Research Network. Sepsis was defined by growth of bacteria or fungi in a blood culture obtained ≤72 hours of birth (EOS) or >72 hours (LOS) and antimicrobial therapy for ≥5 days or death <5 days while receiving therapy. Regression models were used to assess risk of death or LOS by 120 days and LOS by 120 days among survivors to discharge or 120 days, adjusting for gestational age and other covariates. RESULTS: Of 34 396 infants studied, 504 (1.5%) had EOS. After adjustment, risk of death or LOS by 120 days did not differ overall for infants with EOS compared with those without EOS [risk ratio (RR): 0.99 (0.89-1.09)] but was reduced in infants born at <25 weeks gestation [RR: 0.87 (0.76-0.99), P = .048]. Among survivors, no difference in LOS risk was found overall for infants with versus without EOS [RR: 0.88 (0.75-1.02)], but LOS risk was shorter in infants with birth weight 401-750 g who had EOS [RR: 0.80 (0.64-0.99), P = .047]. CONCLUSIONS: Risk of LOS after EOS was not increased in VLBW infants. Surprisingly, risk of LOS following EOS appeared to be reduced in the smallest, most premature infants, underscoring the need for age-specific analyses of immune function.

    ABSTRACT: Background. Children under 2 years of age are at high risk of influenza-related mortality and morbidity. However, the appropriate dose of oseltamivir for children under 2 years of age is unknown.Methods. The National Institute of Allergy and Infectious Diseases Collaborative Antiviral Study Group evaluated oseltamivir in infants from birth to 2 years of age in an age-deescalation, adaptive design with a targeted systemic exposure.Results. From 2006 to 2010, 87 subjects enrolled. An oseltamivir dose of 3.0&emsp14;mg/kg produced drug exposures within the target range in subjects 0 through 8 months of age, although there was a greater degree of variability in infants under 3 months of age. In subjects 9 through 11 months of age, a dose of 3.5&emsp14;mg/kg produced drug exposures within the target range. Six of ten subjects 12 through 23 months of age receiving the FDA-approved unit dose for this age group of 30&emsp14;mg had oseltamivir carboxylate exposures below the target range. Virus from three subjects developed oseltamivir resistance during antiviral treatment.Conclusions. The appropriate twice-daily oral oseltamivir dose for infants birth through 8 months of age is 3.0&emsp14;mg/kg, while the dose for infants 9 through 11 months is 3.5&emsp14;mg/kg.

    ABSTRACT: OBJECTIVE: The objective of our study was to examine the relationship between brain injury and outcome following neonatal hypoxic-ischaemic encephalopathy treated with hypothermia. DESIGN AND PATIENTS: Neonatal MRI scans were evaluated in the National Institute of Child Health and Human Development (NICHD) randomised controlled trial of whole-body hypothermia and each infant was categorised based upon the pattern of brain injury on the MRI findings. Brain injury patterns were assessed as a marker of death or disability at 18-22 months of age. RESULTS: Scans were obtained on 136 of 208 trial participants (65%); 73 in the hypothermia and 63 in the control group. Normal scans were noted in 38 of 73 infants (52%) in the hypothermia group and 22 of 63 infants (35%) in the control group. Infants in the hypothermia group had fewer areas of infarction (12%) compared to infants in the control group (22%). Fifty-one of the 136 infants died or had moderate or severe disability at 18 months. The brain injury pattern correlated with outcome of death or disability and with disability among survivors. Each point increase in the severity of the pattern of brain injury was independently associated with a twofold increase in the odds of death or disability. CONCLUSIONS: Fewer areas of infarction and a trend towards more normal scans were noted in brain MRI following whole-body hypothermia. Presence of the NICHD pattern of brain injury is a marker of death or moderate or severe disability at 18-22 months following hypothermia for neonatal encephalopathy.

    ABSTRACT: Objectives The optimal management of infants born to mothers with peripartum influenza infection is not known. The objective of this study is to describe our experience with a practice guideline that promotes rooming-in and breast-feeding and to determine whether infants managed in this way acquire influenza infection.Study Design All mothers diagnosed with influenza infection within 8 days of delivery and their infants were included. Demographics, clinical characteristics, and outcome data were collected. Mothers were contacted at ~1 month after giving birth to determine if their infants had developed any signs suggestive of influenza infection.Results Forty-two women were diagnosed with peripartum influenza over the 2003 to 2005 and 2009 to 2010 seasons. Median onset of symptoms was 3 days before delivery, and median day of diagnosis was 1 day before delivery. The 42 infants had a median gestational age of 39 weeks; none were born earlier than 35 weeks. Ninety-five percent of the infants roomed-in with their mothers. Follow-up information was available on 95% of infants by 1 month; no infants had illness suggestive of influenza through the follow-up period.Conclusion A guideline for the management of infants born to mothers with peripartum influenza infection, based on attention to hand hygiene, antiviral treatment for mothers, and encouragement of rooming-in and breast-feeding, was not associated with mother-to-infant influenza transmission over three separate influenza seasons.

    ABSTRACT: OBJECTIVE: To determine short-term outcomes of infants who had perinatal acidemia and were evaluated for hypothermia therapy but did not qualify based on a standardized neurologic examination. STUDY DESIGN: Retrospective, single-site cohort study of inborn infants of ≥36 weeks gestation who had perinatal acidemia from October 2005-September 2008 and had a standardized neurologic examination performed by a certified neonatologist to assess eligibility for hypothermia therapy. An abnormal short-term nursery outcome was defined as death, seizures, brain magnetic resonance imaging consistent with hypoxic-ischemic encephalopathy, abnormal neurologic examination at discharge, gastrostomy tube feeding, or inability to nipple all feeds beyond the first week of age. RESULTS: One hundred forty-four (0.3%) of 46 887 newborns with perinatal acidemia had a neurologic examination performed that was either normal (n = 29) or consistent with mild encephalopathy (1 or 2 abnormal categories; n = 60). Of the latter infants classified as having mild encephalopathy, 12 (20%) experienced an abnormal short-term outcome (feeding difficulties, n = 8; abnormal neurologic examination at discharge, n = 7; abnormal brain magnetic resonance imaging, n = 6; seizures, n = 5; gastrostomy, n = 1; or death, n = 1). CONCLUSIONS: Twenty percent of newborns with perinatal acidemia and a neurologic examination that revealed only mild encephalopathy had abnormal short-term outcomes that could be attributed to the encephalopathy. Adjunctive tools or biomarkers for optimal assessment of infants with fetal acidemia for hypothermia therapy are needed.
