Invasive Pulmonary Aspergillosis in a Critically Ill Neonate: Case Report and Review of Invasive Aspergillosis During the First 3 Months of Life

We report a fatal case of invasive pulmonary aspergillosis in a severely ill neonate and review 43 additional cases of invasive aspergillosis reported from 1955 through 1996 that occurred during the first 3 months of life. Eleven of the 44 patients had primary cutaneous aspergillosis, 10 had invasive pulmonary aspergillosis, and 14 had disseminated disease. Most infections were nosocomial in origin. Prematurity (43%); proven chronic granulomatous disease (14%); and a complex of diarrhea, dehydration, malnutrition, and invasive bacterial infections (23%) accounted for the majority of underlying conditions. At least 41% of the patients had received corticosteroid therapy before diagnosis, but only one patient had been neutropenic. Among patients who received medical and/or surgical treatment, outcome was relatively favorable, with an overall survival rate of 73%. Invasive aspergillosis may occur in neonates and young infants and warrants consideration under certain circumstances. Current therapeutic approaches consist of high-dose amphotericin B and appropriate surgical interventions.

Three-Dimensional Body Scanning: A New Method to Estimate Body Surface Area in Neonates

Background: Body surface area (BSA) is usually estimated by calculation with mathematical formulae. Three-dimensional body scanning (3D scan) offers a suitable alternative. Objectives: We determined the BSA in healthy term and near-term neonates by 3D scanning. This system should be useful in the setting of intensive care medicine. Methods: The measuring system consisted of a projector, two cameras, mirrors and a computer, and used the fringe projection technique with visible light. The infants were examined in a supine position; the hidden parts of the bodies were corrected for using a mathematical factor developed with a baby doll model. Results of the 3D scans were compared with those from five mathematical formulae for each subject. Results: A total of 209 infants were studied by 3D scanning, of whom 53 had acceptable images and were selected for further analysis. The mean BSA was 2,139 cm2 (SD 223.72). The minimal BSA was 1,587 cm2, the maximal 2,670 cm2, with a good correlation to body weight and length. One mathematical formula (Du Bois and Du Bois) showed a distinct underestimation of BSA compared to 3D scanning, the others an overestimation. Mean percentage similarity was from 96.8 to 100.9%. Conclusions: 3D scanning is an accurate and practical method to estimate BSA in newborns. Individual and repeated measurements from day to day are possible. Further studies are warranted in preterm and sick neonates.

Follow-Up of Children with Gastrointestinal Malformations and Postnatal Surgery and Anesthesia: Evaluation at Two Years of Age

Background: The impact of general anesthesia is considered a risk factor for developmental delay. Very few studies have been performed to measure the neurodevelopmental outcome of patients with selected malformations. Objectives: The purpose of this ambidirectional cohort study was to measure the neurodevelopmental outcome of patients with congenital gastrointestinal-tract malformations (GIM). Methods: Forty patients with relevant congenital GIM born in the period from June 2008 to April 2011 were identified. The inclusion criteria were a gestational age >32 completed weeks and surgery that required a general anesthetic within the first 28 days of life. The neonatal characteristics and anesthesia data were retrospectively collected. Based on information about the neonatal characteristics and socioeconomic background, a matched pair was found. All participants were tested at the corrected age of 24 months with the Bayley Scales of Infant Development II assessment. Results: The outcome was split into the psychomotor index (PDI) and mental developmental index (MDI). The patient group achieved a mean PDI of 103 and the control group achieved 106, i.e. these values were not significantly different. The mean MDI was 102 in the patient group and 110 in the control group. This difference was significant (p = 0.022). Detailed analysis of the items showed no significance for nonverbal items but a significant difference for verbal items (p = 0.029). Further analysis showed no correlation between relevant anesthesia data and the neurodevelopmental outcome. Conclusions: We found lower MDI scores due to worse verbal abilities in the patient group. Children born with GIM should be considered a risk group with respect to language development.

Purpura Fulminans after Therapeutic Hypothermia in an Asphyxiated Neonate with Streptococcemia

OBJECTIVE Therapeutic hypothermia is an established therapeutic regimen in severely asphyxiated term neonates. The amount of cerebral injury is reduced resulting in an improved neurologic outcome. Therapeutic hypothermia-induced side effects mostly affect the circulatory system, kidney, and liver. However, asphyxia and hypothermia in itself reduce the hemostatic capacity of each individual organism. STUDY DESIGN A case of a neonate with severe asphyxia and purpura fulminans after hypothermia is described. RESULTS AND CONCLUSION Although purpura fulminans cannot be attributed to hypothermia solely, the influence of hypothermia on hemostasis may have promoted severe coagulopathy with a fatal outcome. Further studies are necessary to reveal therapeutic hypothermia as a trigger for severe coagulopathies in asphyxiated neonates, especially in those with sepsis and overt coagulopathy prior to therapeutic hypothermia.

Group B streptococcus infections in neonates admitted to a German NICU: Emphasis on screening and adherence to pre-analytical recommendations

BACKGROUND Infections by group B streptococci (GBS), e.g. Streptococcus agalactiae, presenting as early-onset disease (EOD) or late-onset disease (LOD), are leading causes of severe infections in newborn and premature patients. Although screening and intra partum antibiotic prophylaxis are frequently performed, vertically transmitted GBS remain a challenge for pediatrics. AIMS In order to prevent or reduce potential life-threatening events, this study retrospectively investigated epidemiological, microbiological and clinical aspects of infants admitted to the Division of Neonatology at the Department of Pediatrics at the University Hospital Frankfurt, Germany (UHF). STUDY DESIGN AND SUBJECTS Between January 2010 and January 2016, perinatal GBS screening status, clinical presentation of EOD or LOD and therapeutic management of neonates admitted to UHF were retrospective analysed. Infants tested positive for GBS within their first three months of life were included; patient data were obtained from the chart report. Severity of neonatal disease was analysed by using the NEOMOD and CRIB score. RESULTS 108 GBS infected infants born to 105 mothers were observed. N=101 of them (93.5%) presented with EOD, whereof n=9 (10%) primarily presented with pneumonia or pneumothorax. In 82 (78%) mothers of infected infants GBS status was unknown prior to hospitalization of the neonate. 3/108 (2.8%) infants died from GBS septicemia. CONCLUSION Avoidance of GBS transmission sub partu is the key issue in preventing neonatal GBS infection and should be the focus of preventive strategies. Our results highlight the impact of perinatal screening.
