Child Public Health professionals in the Netherlands refer obese children to a pediatrician to check for underlying causes and comorbidity. What happens to these children in terms of diagnostics and treatment when they visit a pediatrician? To get an overview of the diagnostic procedures and treatment methods a questionnaire was developed and sent to all 583 pediatricians in the Netherlands. Data was obtained of 290 pediatricians from 85% of the general hospitals and all (8) academic hospitals. To define childhood obesity Dutch pediatricians most often use the adult Body Mass Index, only 34% use the sex and age specific IOTF-BMI-criteria. 11% of the (non-obese) overweight children visiting a pediatrician have already comorbidities. All pediatricians perform at least weight and height measurements. Waist circumference is measured by only 42%, ninety-five percent measure blood pressure. To treat obese children without comorbidity thirty different intervention programs were reported. A large variation in diagnostics and interventions of childhood obesity exist. Guidelines in pediatric obesity for diagnostics and treatment are urgently needed. © 2013 Elsevier Ireland Ltd.

Familial hemophagocytic lymphohistiocytosis (FHLH) is a genetic heterogeneous autosomal recessive disorder. We report two siblings with FHLH caused by a PRF1 mutation. The first child died in utero with hydrops fetalis and the second presented soon after birth with fatal multiple organ failure. Post-mortem DNA analysis showed a homozygous c.666C>A (p.His222Gln) mutation in the PRF1 gene in both cases, with their non-consanguineous parents being heterozygous for the same mutation. Review of the literature shows that perinatal presentation of FHLH is rare. Diagnosis is difficult because in most cases histologic examination reveals no hemophagocytosis and the disease is rapidly fatal. The association between hydrops fetalis and FHLH has been reported in four previous reports. We present the first case of hydrops fetalis caused by FHLH, confirmed by DNA analysis. FHLH should be included in the differential diagnosis of non-immune hydrops fetalis and neonatal multiple organ failure. (C) 2009 Elsevier Masson SAS. All rights reserved

In a previous study, we found that glutamine-enriched enteral nutrition in 102 very low-birth-weight (VLBW) infants decreased both the incidence of serious neonatal infections and atopic dermatitis during the first year of life. The aims of this follow-up study were to determine whether these beneficial effects are attended by changes in Th(1) and Th(2) cytokine profiles at age 1 yr. Furthermore, we studied changes in cytokine profiles during the first year of life in these VLBW infants. In total, 89 infants were eligible for the follow-up study (12 died, 1 exclusion due to a chromosomal abnormality). Th(1) (IFN-gamma, TNF- alpha and IL-2) and Th(2) cytokine (IL-10, IL-5, and IL-4) profiles following in vitro whole blood stimulation were measured at 1 yr. Cytokine profiles were measured in 59/89 (66%) infants. Glutamine-enriched enteral nutrition in neonatal period did not influence cytokine profiles at 1 yr. Cytokine profiles were not different in infants with and without allergic or infectious diseases. The beneficial effect of glutamine-enriched enteral nutrition on the incidence of serious neonatal infections and atopic dermatitis during the first year of life is not related to changes in the Th(1) and Th(2) cytokine profiles. Both Th(1) and Th(2) cytokine profiles increased during the first year of life in this cohort of VLBW infants.

OBJECTIVE:: Very low birth weight (VLBW) infants receiving glutamine-enriched enteral nutrition may present with a lower infection rate, which may result from enhanced antimicrobial innate or Th1 cytokine responses. We investigated whether glutamine-enriched enteral nutrition in VLBW infants increased these cytokine responses following in vitro stimulation of whole blood cells. METHODS:: In a double-blind, placebo-controlled, randomized controlled trial, VLBW infants (gestational age

In contrast with clinical studies in term infants or older children, it is very difficult to investigate possible immunoregulatory effects of a novel infant formula composition in preterm infants. This is mainly because of the multicausal origin of infections in this high-risk population that is usually admitted to the neonatal intensive care unit. Possible effects of nutrition composition on onsetand incidence of nosocomial infections in these very small infants have to be compared with infections that may have originated in utero. The development of the gastrointestinal tract may be inhibited after severe intrauterine growth retardation, leading to functional impairment of the gut shortly after birth. This may be related to the onset of necrotizing enterocolitis of the newborn. However, this disease in very small preterm infants is possibly also related to the initiation of oral feeding and/or the amount of feeding. Specific infection risks of neonatal intensive care as a result of invasive techniques such as artificial ventilation or total parenteral nutrition using indwelling umbilical and/or Silastic lines and so-called "all-in-one" mixtures may influence the incidence of infections. Widespread use of intravenous antibiotics in the neonatal intensive care unit may create an even larger infection risk. Investigation of possible immunomodulatory effects of factors such as prebiotics and probiotics added to the nutrition of preterm infants should always be considered along with other nutritional factors known to influence the immature immune system.

Functional mannose-binding lectin (f-MBL) plays an important role in the innate neonatal immune system. We studied the origin of f-MBL in umbilical cord blood (UCB) by measuring maternal MBL (n=47), collected before elective cesarean section, and neonatal MBL (n=43) in arterial umbilical cord blood. In a subgroup, arterial and venous UCB MBL levels were measured. In addition, MBL expression was correlated with genetic mutations. The f-MBL levels in term infants were lower than in their mothers (0.70 microg/ml vs 1.11 microg/ml, p

Background: Very-low-birth-weight (VLBW) infants are susceptible to glutamine depletion. Glutamine depletion has negative effects on intestinal integrity. The lower infection rate in VLBW infants receiving glutamine-enriched enteral nutrition may originate from improved intestinal integrity, as reflected by decreased intestinal permeability. The aim of our study was to investigate whether glutamine-enriched enteral nutrition in VLBW infants enhances the normal decrease in intestinal permeability, as measured by the sugar absorption test (SAT). Methods: In a double-blind, randomized, placebo-controlled trial, VLBW infants (gestational age

The aim of this study is to review the normal development of the intestinal microflora of preterm infants and the factors influencing its development. Preterm infants have an increased intestinal permeability, which may lead to bacterial. translocation to systemic organs and tissues. In combination with immaturity of the immune system the risk to systemic infections might be increased. Especially potential pathogenic bacteria are able to translocate. The intestinal microflora of breast-fed term infants, dominated by bifidobacteria and lactobacilli, is thought to suppress the growth of potentially pathogenic bacteria. Many attempts have been made to stimulate the presence of bifidobacteria and lactobacilli with changes in the diet and ingredients-like prebiotics and probiotics. After selection, six studies were included reviewing the intestinal bacterial colonisation of preterm infants. In general, these studies show that the intestinal bacterial colonisation with beneficial bacteria is delayed in preterm infants. The number of potentially pathogenic bacteria is high. Antibiotics influence the intestinal colonisation. Many preterm infants receive prophylactic antibiotics at birth. As antibiotics delay the normal intestinal colonisation, caution should be given to the treatment with broadspectrum antibiotics in preterm infants at birth and every attempt has to be made to restrict the period of treatment.

Objectives Plasma volume expansion may benefit both mother and child in the temporising management of severe and early onset hypertensive disorders of pregnancy. Design Randomised clinical trial. Setting Two university hospitals in Amsterdam, The Netherlands. Population Two hundred and sixteen patients with a gestational age between 24 and 34 completed weeks with severe pre-eclampsia, haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome or severe fetal growth restriction (FGR) with pregnancy-induced hypertension, admitted between 1 April 2000 and 31 May 2003. Methods One hundred and eleven patients were randomly allocated to the treatment group, (plasma volume expansion and a diastolic BP target of 85-95 mmHg) and 105 to the control group (intravenous fluid restriction and BP target of 95-105 mmHg). Main outcome measures Neonatal neurological development at term age (Prechtl score), perinatal death, neonatal morbidity and maternal morbidity. Results Baseline characteristics were comparable between groups. The median gestational age was 30 weeks. In the treatment group, patients received higher amounts of intravenous fluids (median 813 mL/day vs 14 mL/day; P 21% (66 vs 46; P= 0.09) in the treatment group was observed. There was no difference in major maternal morbidity (total 11%), but there were more caesarean sections in the treatment group (98%vs 90%; P

Objective: Glutamine depletion has negative effects on the functional integrity of the gut and leads to immunosuppression. Very low birth weight (VLBW) infants are susceptible to glutamine depletion, as enteral nutrition is limited in the first weeks of life. Enteral glutamine supplementation may have a positive effect on feeding tolerance, infectious morbidity and short-term outcome. The aim of the study was to determine the effect of enteral glutamine supplementation on plasma amino acid concentrations, reflecting one aspect of safety of enteral glutamine supplementation in VLBW infants. Methods: In a double-blind placebo-controlled randomized controlled trial, VLBW infants (gestational age

To determine the value of noninvasive assessment of right ventricular preload in neonates, a prospective unblinded study was performed. Thirty-seven neonates without heart disease (median birth weight 1390 g, range 900 to 4400) were studied at the neonatal intensive care unit, comparing directly measured central venous pressure (CVP) and two-dimensional echocardiographic measurement of the maximum and minimum diameter of the inferior vena cava and calculated vena cava index (VCI). CVP was higher in conventionally ventilated and high-frequency oscillatory ventilated neonates than in those breathing spontaneously ( p < 0.0001). VCI in high-frequency oscillatory ventilated patients was lower (5 +/- 4) than in spontaneously breathing (56 +/- 19) and conventionally ventilated (49 +/- 19) (p = 0.002) neonates. CVP and VCI were inversely correlated in spontaneously breathing (r = -0.631), but not in conventionally and high-frequency oscillatory ventilated patients. VCI does not predict CVP in ventilated premature neonates, the correlation is limited only to spontaneously breathing infants.

OBJECTIVE: To investigate whether epileptic seizure activity can be distinguished from non-epileptic background activity in the neonatal electroenceplalogram (EEG), using synchronization likelihood as a measure of synchronization between EEG channels.METHODS: Forty-two 21s EEG epochs and two complete EEGs from 21 different neonatal patients in a 12-channel bipolar recording were studied (AD-conversion 16bit; sample frequency 200Hz; filter setting 0.5-30Hz). For EEG of each patient, we selected one epoch with epileptic discharges and one without. Synchronization was calculated in all epochs. In two complete EEGs, synchronization was calculated and correlated with a visual scoring of the EEG.RESULTS: Synchronization likelihood was higher in all the epochs with epileptic seizures as compared to the epochs without epileptic activity (PCONCLUSIONS: The results of this study demonstrate that synchronization likelihood is a potential tool in the automatic monitoring of high-risk infants for epileptic activity on neonatal wards.

The aim of the study was to find if neurological function during the first year of life could predict neuromotor behaviour at 7 years of age in children born preterm with a high risk. A follow-up study of neuromotor behaviour in 52 children at a mean age of 3, 6, 12 months (corrected age) and 7 years was performed. All children were born with a gestational age less than 32 weeks and/or a birthweight under 1500 g and the infants were categorised according to their medical history in the three highest categories of the 'Neonatal Medical Index' (NMI, from category I to V, from few to serious complications). In addition, neonatal cerebral ultrasound abnormalities were used to divide the infants further into the different NMI categories. At 3 and 6 months, the relationship between active and passive muscle power was measured in shoulders, trunk and legs and (a)symmetry between right and left was noted. The results at 3 and 6 months were ranged from 1 for optimal to 5 for poor muscle power regulation. At 12 months of age, a neurological examination was done with special emphasis on the assessment of postural control, spontaneous motility, hand function and elicited infantile reactions with special attention to (a)symmetry. Outcome at 12 months was expressed as percentage of the optimal score on each subcategory. At 7 years, the motor behaviour study based on Touwen's examination for minor neurological dysfunction was performed. This investigation focuses on different functions, such as hand function, quality of walking, posture, passive muscle tone, coordination and diadochokinesis. The outcome was expressed as percentage of the optimal score on the combined subcategories. The best prediction of neuromotor behaviour at 7 years was assessed with stepwise linear multiple regression, using as potential predictors perinatal factors and outcome of motor behaviour at the corrected age of 3, 6 and 12 months. At 7 years none of the children scored 100% on the combined subcategories, 15 children (29%) scored between 75% and 99%, whereas 15 children scored less than 50%. Neuromotor behaviour at 7 years could be predicted by the NMI categorisation and gender with a sensitivity of 92% (specificity 47%; positive and negative predictive value 81% and 70%). No direct relation was found between neuromotor behaviour and cerebral ultrasound classification only, days on the ventilator and/or continuous positive airway pressure, birthweight, gestational age and dysmaturity. The best predictor of neuromotor behaviour at 7 years was the combination of outcome of muscle power in shoulders and legs at 3 months and postural control at 12 months, taking into account the gender of the child (sensitivity 95%; specificity 40%; positive predictive value 80%; negative predictive value 75%). © 2002 Elsevier Science Ireland Ltd.

Respiratory morbidity is an important complication of elective caesarean section. The presence of labour preceding caesarean section reduces the risk of neonatal respiratory morbidity. Recently, it has been shown that the incidence of respiratory morbidity is lower in infants with a gestational age of at least 39 +0 weeks at elective caesarean section compared to infants with a gestational age less than 39 +0 weeks. This article describes the results of a 5-year retrospective study on the incidence of respiratory distress in term neonates delivered by elective caesarean section in relation to gestational age and provides a literature review on neonatal respiratory morbidity following elective caesarean section.

Isolated noncompaction of the ventricular myocardium is a cardiomyopathy influencing almost exclusively the left ventricle in children and adults. We report a case of a neonate presenting with right ventricular failure caused by a noncompaction of the right ventricle. However, later course of the disease demonstrated biventricular involvement. Right ventricular noncompaction can be a cause of early postnatal right ventricular failure.

Objectives To systematically investigate the causes and severity of incidents with mechanical ventilation and intravascular catheters in neonatal intensive care units (NICUs) in the Netherlands, in order to develop effective strategies to prevent such incidents in the future. Design Prospective multicentre survey. Methods Inclusion criteria were: incidents with mechanical ventilation and intravascular catheters reported to a voluntary, non-punitive, incident-reporting system which had been systematically analysed using the Prevention Recovery Information System for Monitoring and Analysis (PRISMA)-Medical method. The type, severity and causes of incidents reported from 1 July 2005 to 31 March 2007 are described. Local interventions performed as a result of systematic analysis of incidents are also described. Results 533 of 1306 (41%) reported incidents with mechanical ventilation and intravascular catheters (n=339/856 and n=194/450, respectively) had been PRISMA analysed and were included in the study. Four incidents resulted in severe harm, 18 in moderate harm and 222 in minor harm. Tube-related incidents accounted for the greatest proportion of harm. 1233 root causes were identified, with most being classified as human error (55%). Of the remaining failures, 20% were organisational, 16% technical, 6% patient-related and 4% unclassifiable. The majority of failures were rule-based errors. Conclusion Incidents with mechanical ventilation and intravascular catheters occur regularly in NICUs, and frequently harm patients. Multicentre, systematic analysis increases our knowledge of these events. Continuous training and education of all NICU personnel is required, together with preventive strategies aimed at the whole system – including the technical and organisational environment – rather than at human failure alone.

The gastrointestinal inflammatory response may play a role in the susceptibility of preterm infants for infections. We previously reported a trend toward lower endogenous infection morbidity after enteral supplementation of neutral and acidic oligosaccharides (SCGOS/LCFOS/AOS). We hypothesize that enteral supplementation of prebiotics may decrease infectious morbidity by reducing intestinal inflammation. Therefore, we aimed to determine the effect of enteral supplementation of prebiotics on intestinal inflammation, as measured by fecal IL-8 (f-IL-8) and calprotectin (f-calprotectin), in preterm infants. In a randomized controlled trial, infants with a GA

In a previous randomised controlled trial, we found that glutamine-enriched enteral nutrition in 102 very low birthweight (VLBW) infants decreased both the incidence of serious infections in the neonatal period and the risk of atopic dermatitis during the first year of life. We hypothesised that glutamine-enriched enteral nutrition in VLBW infants in the neonatal period influences the risk of allergic and infectious disease at 6 years of age. Eighty-eight of the 102 infants were eligible for the follow-up study (13 died, 1 chromosomal abnormality). Doctor-diagnosed allergic and infectious diseases were assessed by means of validated questionnaires. The association between glutamine-enriched enteral nutrition in the neonatal period and allergic and infectious diseases at 6 years of age was based on univariable and multivariable logistic regression analyses. Seventy-six of the 89 (85%) infants participated, 38 in the original glutamine-supplemented group and 38 in the control group. After adjustment, we found a decreased risk of atopic dermatitis in the glutamine-supplemented group: adjusted odds ratio (aOR) 0.23 [95% CI 0.06, 0.95]. No association between glutamine supplementation and hay fever, recurrent wheeze and asthma was found. A decreased risk of gastrointestinal tract infections was found in the glutamine-supplemented group (aOR) 0.10 [95% CI 0.01, 0.93], but there was no association with upper respiratory, lower respiratory or urinary tract infections. We concluded that glutamine-enriched enteral nutrition in the neonatal period in VLBW infants decreased the risk of atopic dermatitis and gastrointestinal tract infections at 6 years of age.

Preterm infants have an impaired gut barrier function. We aimed to determine the effects of enteral supplementation of a prebiotic mixture consisting of neutral oligosaccharides (short-chain galacto-oligosaccharides (SCGOS)/long-chain fructo-oligosaccharides (LCFOS)) and acidic oligosaccharides (AOS) on intestinal permeability of preterm infants as measured by the sugar absorption test in the first week of life. Furthermore, we determined host- and treatment-related factors associated with intestinal permeability. In a randomised controlled trial, preterm infants with a gestational age SCGOS/LCFOS/AOS or placebo (maltodextrin) between days 3 and 30 of life. Intestinal permeability, reflected by the urinary lactulose/mannitol (L/M) ratio after oral ingestion of lactulose and mannitol, was assessed at three time points: before the start of the study (t = 0), at day 4 (t = 1) and at day 7 (t = 2) of life. Data were analysed by generalised estimating equations. In total, 113 infants were included. Baseline patient and nutritional characteristics were not different between the SCGOS/LCFOS/AOS (n 55) and the placebo groups (n 58). SCGOS/LCFOS/AOS had no effect on the L/M ratio between t = 0 and t = 2. In both the groups, the L/M ratio decreased from t = 0 to t = 2 (P P = 0·002). Exclusive breast milk feeding and mixed breast milk/formula feeding during the first week of life decreased the L/M ratio (P P

OBJECTIVES: Safety culture assessments are increasingly used to evaluate patient-safety programs. However, it is not clear which aspects of safety culture are most relevant in understanding incident reporting behavior, and ultimately improving patient safety. The objective of this study was to examine which aspects of safety culture predict incident reporting behavior in the neonatal intensive care unit (NICU), before and after implementation of a voluntary, nonpunitive incident reporting system. DESIGN: Survey study based on a translated, validated version of the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture. This survey incorporates two outcome measures, 11 dimensions of patient-safety culture as well as demographic data. SETTING: Eight tertiary care NICUs and one surgical pediatric ICU. SUBJECTS: All unit personnel. INTERVENTION: Implementation of a specialty-based, voluntary, nonpunitive incident reporting system. MEASUREMENTS AND MAIN RESULTS: The survey was conducted before (t = 0) and after (t = 1 yr) the intervention. Primary outcome: number of self-reported incidents in the past 12 months. Overall response rate was 80% (n = 700) at t = 0 and 76% (n = 670) at t = 1 yr. Based on a multivariate multilevel regression prediction model, the number of self-reported incidents increased after the intervention and was positively associated with a nonpunitive response to error and negatively associated with overall perceptions of safety and hospital management support for patient safety. CONCLUSIONS: A nonpunitive approach to error, hospital management support for patient safety, and overall perceptions of safety predict incident reporting behavior in the NICU. The relation between these aspects of safety culture and patient outcome requires further scrutiny and therefore remains an important issue to address in future research

In contrast with clinical studies in term infants or older children, it is very difficult to investigate possible immunoregulatory effects of a novel infant formula composition in preterm infants. This is mainly because of the multicausal origin of infections in this high-risk population that is usually admitted to the neonatal intensive care unit. Possible effects of nutrition composition on onset and incidence of nosocomial infections in these very small infants have to be compared with infections that may have originated in utero. The development of the gastrointestinal tract may be inhibited after severe intrauterine growth retardation, leading to functional impairment of the gut shortly after birth.

BackgroundPrevention of serious infections in preterm infants is a challenge, since prematurity and low birth weight often requires many interventions and high utility of devices. Furthermore, the possibility to administer enteral nutrition is limited due to immaturity of the gastrointestinal tract in the presence of a developing immune system. In combination with delayed intestinal bacterial colonisation compared with term infants, this may increase the risk for serious infections. Acidic and neutral oligosaccharides play an important role in the development of the immune system, intestinal bacterial colonisation and functional integrity of the gut. This trial aims to determine the effect of enteral supplementation of acidic and neutral oligosaccharides on infectious morbidity (primary outcome), immune response to immunizations, feeding tolerance and short-term and long-term outcome in preterm infants. In addition, an attempt is made to elucidate the role of acidic and neutral oligosaccharides in postnatal modulation of the immune response and postnatal adaptation of the gut.Methods/DesignIn a double-blind placebo controlled randomised trial, 120 preterm infants (gestational age DiscussionEspecially preterm infants, who are at increased risk for serious infections, may benefit from supplementation of prebiotics. Most studies with prebiotics only focus on the colonisation of the intestinal microflora. However, the pathways how prebiotics may influence the immune system are not yet fully understood. Studying the immune modulatory effects is complex because of the multicausal risk of infections in preterm infants. The combination of neutral oligosaccharides with acidic oligosaccharides may have an increased beneficial effect on the immune system. Increased insight in the effects of prebiotics on the developing immune system may help to decrease the (infectious) morbidity and mortality in preterm infants.Trial registrationCurrent Controlled Trials ISRCTN16211826.

Objectives The purpose of this study was to compare 3D lung volume measurements with 2D biometric parameters in predicting pulmonary hypoplasia in pregnancies complicated by preterm premature rupture of the membranes (PPROM). Methods In this prospective study, 18 pregnancies complicated by PPROMs at a mean 21 weeks' gestation (range 14–32 weeks) were examined. The 3D lung volume measurements and the following 2D biometric parameters were measured: thoracic circumference (TC) versus gestational age or femur length (FL), the TC/abdominal circumference (AC) ratio and the thoracic area/heart area (TA/HA) ratio. The sensitivity, specificity, positive and negative predictive value of each measurement to diagnose pulmonary hypoplasia were compared. Pulmonary hypoplasia was diagnosed on the basis of clinical, radiological and/or pathologic criteria. Results The incidence of pulmonary hypoplasia was 33.3%. The best diagnostic accuracy for predicting pulmonary hypoplasia was achieved using the 3D lung volume measurements versus gestational age (sensitivity 83%, specificity 100%, positive predictive value 100% and negative predictive value 92%). Conclusions Three-dimensional lung volume measurements seem to be promising in predicting pulmonary hypoplasia prenatally in pregnancies complicated by PPROM.

Background & aims: In a previous study, we have found that glutamine supplementation decreased the infection rate in very low birth weight (VLBW) infants. In this study, we investigated whether this beneficial effect originated from increased number of bifidobacteria and lactobacilli in the intestinal microflora of these infants. Methods: In a randomized controlled trial, VLBW infants (gestational age 0.05). In both groups, colonization with bifidobacteria was delayed, whereas potentially pathogenic bacteria such as E. coli, appeared rapidly after birth. Antibiotic treatment decreased the prevalence of all faecal bacteria (p

Background: Glutamine depletion has negative effects on the functional integrity of the gut and leads to immunosuppression. Very-low-birth-weight (VLBW) infants are susceptible to glutamine depletion because nutrition is limited in the first weeks of life. Objective: The objective was to determine the effect of glutamine-enriched enteral nutrition on feeding tolerance, infectious morbidity, and short-term outcome in VLBW infants. Design: In a double-blind randomized controlled trial, VLBW infants (gestational age = 1 serious infection compared with 38 of 50 (76%) in the control group (odds ratio: 0.32; 95% CI: 0.14, 0.74; P = 0.008). Other variables of feeding tolerance and short-term outcome were not significantly different between groups. Conclusions: Glutamine-enriched enteral nutrition did not improve feeding tolerance or short-term outcome in VLBW infants. However, infectious morbidity was significantly lowered in infants who received glutamine-enriched enteral nutrition

Background Enteral feeding of very low birth weight (VLBW) infants is a challenge, since metabolic demands are high and administration of enteral nutrition is limited by immaturity of the gastrointestinal tract. The amino acid glutamine plays an important role in maintaining functional integrity of the gut. In addition, glutamine is utilised at a high rate by cells of the immune system. In critically ill patients, glutamine is considered a conditionally essential amino acid. VLBW infants may be especially susceptible to glutamine depletion as nutritional supply of glutamine is limited in the first weeks after birth. Glutamine depletion has negative effects on functional integrity of the gut and leads to immunosuppression. This double-blind randomised controlled trial is designed to investigate the effect of glutamine-enriched enteral nutrition on feeding tolerance, infectious morbidity and short-term outcome in VLBW infants. Furthermore, an attempt is made to elucidate the role of glutamine in postnatal adaptation of the gut and modulation of the immune response. Methods VLBW infants (gestational age

Item does not contain fulltext BACKGROUND: To determine: 1) whether substandard factors were present in cases of perinatal death, and to what extent another course of action might have resulted in a better outcome, and 2) whether there were differences in the frequency of substandard factors by level of care, particularly between midwives and gynecologists/obstetricians and between home and hospital births. METHODS: Population-based perinatal audit, with explicit evidence-based audit criteria. SETTING: The northern part of the province of South-Holland in The Netherlands. All levels of perinatal care (primary, secondary and tertiary care, and home and hospital births) were included. CASES: Three hundred and forty-two cases of perinatal mortality (24 weeks of pregnancy--28 days after birth). MAIN OUTCOME MEASURES: Scores by a Dutch and a European audit panel. Score 0: no substandard factors identified; score 1, 2 or 3: one or more substandard factors identified, which were unlikely (1), possibly (2) or probably (3) related to the perinatal death. RESULTS: In 25% of the perinatal deaths (95% Confidence Interval: 20-30%) a substandard factor was identified that according to the Dutch panel was possibly or probably related to the perinatal death. These were mainly maternal/social factors (10% of all perinatal deaths; most frequent substandard factor: smoking during pregnancy), and antenatal care factors (10% of all perinatal deaths; most frequent substandard factor: detection of intra-uterine growth retardation). We did not find statistically significant differences in scores between midwives and gynecologists/obstetricians or between home and hospital births. The European panel identified more substandard factors, but these were again equally distributed by level of care. CONCLUSIONS: Perinatal deaths might be partly preventable in The Netherlands. There is no evidence that the frequency of substandard factors is related to specific aspects of the perinatal care system in The Netherlands.

Our goal for this study was to determine whether the maturation of fat absorption in neonatal life is functionally related to an increased ability to hydrolyze dietary fat, to absorb long-chain fatty acids, or to do both. In 16 preterm and in eight term neonates, the intestinal ability to hydrolyze triacylglycerols and the capacity to absorb long-chain fatty acids were determined at several times between birth and 5 mo after the term age. These processes were compared with the percentage of fat absorption (formula-fed infants) or with fecal fat excretion (breast-fed infants). The functional capacity to digest triacylglycerols and to absorb the lipolytic products was evaluated by measuring serum concentrations of the lipolytic product [1-(13)C]palmitate after the enteral administration of tri-1-(13)C palmitoyl-glycerol. Long-chain fatty acids absorption (i.e. independent of lipolysis) was determined by measuring serum concentrations of [1-(13)C]stearate after its enteral administration. The efficacy of fat absorption increased in preterm infants (formula-fed) from 91.2 +/- 1.1% (mean +/- SEM) at 32.3 wk postconceptional age (PCA) to 97.3 +/- 0.6% at 53.6 wk PCA (p < 0.001), and in term infants from 91.7 +/- 1.8% (40.0 wk PCA) to 97.4 +/- 1.3% (58.9 wk PCA, p = 0.07). Both the serum concentration of [1-(13)C]stearate and that of [1-(13)C]palmitate appeared highly correlated with the efficacy of fat absorption (r = 0.82, p = 0.02; and r = 0.91, p = 0.004; respectively) and with PCA (r = 0.99, p < 0.001; and r = 0.85, p < 0.02; respectively). These results indicate that the functional development of fat absorption in preterm and term infants is related to the capacity to absorb long-chain fatty acids from the intestine.

Neuromotor behavior was studied in 63 children at a mean age of 7 years. They were born at a gestational age less than 32 weeks and/or birthweight under 1500 g and were categorized according to their medical history in conformance with the Neonatal Medical Index (from category I to V, from few to serious complications). We included only children considered at high risk as categorized in III to V. The neuromotor behavior study focuses on different subcategories, such as hand function, quality of walking, posture, passive muscle tone, coordination, and diadochokinesia. Hand preference and/or lateralization, the presence of associated movements, and/or asymmetry were noted, as was school performance. Then gender, gestational age, birthweight, and dysmaturity were investigated as confounding factors. The outcome at 7 years was correlated with the Neonatal Medical Index and the neonatal brain ultrasonography classification. None of the children scored 100% on the combined subcategories. Nineteen children (30%) had an overall score between 75 and 99%. Significant relationships between all different subcategories were found. Lack of hand preference, poor lateralization, and male gender were related to poor overall outcome. Poor motor control was correlated to special schooling and education below age level. The Neonatal Medical Index proved to have a significant influence on total outcome and the subcategories at the age of 7 years, with the worst outcome in children formerly classified in category V. Neuromotor behavior at 7 years of age was not related to birthweight, gestational age, dysmaturity, and neonatal brain ultrasonography classification only. (J Child Neurol 2002;17:325-332).

Influenza B infection typically has low mortality. A 1,020-g neonate had a septic clinical picture and pneumonia. Influenza B virus was isolated from nasopharyngeal and tracheal aspirates. The infant died.

We describe four newborns (gestational ages 29-37 weeks; birthweights 1380-3040 grams) who were mechanically ventilated for respiratory insufficiency because of bacterial sepsis. A beneficial effect of bovine surfactant (Alvofact, dosages 50 or 100 mg/kg) was found, as shown by decreases in mean airway pressures and oxygen demands. No side effects were seen after instillation.

We describe a newborn infant with Streptococcus sanguis septicaemia and concomitant upper airway obstruction due to epiglottitis and pharyngitis. This rare infection of the supraglottic region was treated with endotracheal intubation and antibiotics. Full recovery occurred within 4 days.

Fat Malabsorption in Preterm and Term Neonates Is Not Due to Insufficient Lipolysis, but to Impaired Uptake of Long Chain Fatty Acids from the Intestinal Lumen

Background: Maturation of the small bowel barrier continues after birth. Intestinal permeability for macromolecules is thought to reflect this barrier function. Intestinal permeability can be measured by the Sugar Absorption Test (SAT). Aim: To determine the relation between intestinal permeability, as measured by the SAT, and gestational age, birth weight, postnatal age and perinatal factors (gestational age, birth weight, umbilical pH, APGAR 5′, enteral feeding, days on ventilator, age (in h) at first SAT). Methods: In the SAT, the Lactulose/Mannitol (L/M) ratio is measured in 6h urine after oral ingestion. The SAT was performed within 48h after birth (median 24h, range 4-48) in 108 unselected premature infants, gestational age (median, range) 31.3wk (27-36.6), birth weight 1415g(665-2720). In 94/108 (87%), the SAT was repeated after 5-7d. Results: The L/M ratio was not related to gestational age (r=0.09, p=0.34) nor birth weight (r=0.07, p=0.50). The L/M ratio (median) decreased within 5-7d after birth (0.497 vs 0.257, p < 0.001). Multivariant regression showed that umbilical pH is the best predicting factor of the L/M ratio within 48h after birth. Conclusions: Intestinal permeability, as measured by the SAT, is not related to gestational age nor birth weight, but decreases with increasing postnatal age. Umbilical pH is related to intestinal permeability measured within 48h after birth.

Intestinal Permeability in Preterm Neonates is not Related to Gestational Age or Birth Weight. 75

Publisher Summary This chapter describes a microcomputer based monitoring system for the measurement of transcutaneous oxygen tension. A microcomputer based monitoring system is presented for storage and quantitative analysis of long-term transcutaneous oxygen tension recordings. The tcPO2 is measured by a skin-electrode developed and manufactured in laboratory. The tcPO2 electrode signal is processed by a commercially available microcomputer system. This system consists of a processor ITT 2020, which is Apple compatible with a total memory of 64 k and, two floppy disk-drives each with a capacity of approximately 140 kbyte for background storage and, a 9-inch video display for text and graphic representations, and a matrix printer. The interrupt handler written in assembler takes care of the tasks such as the sampling of the tcPO2 signal with an interval of 1s, and mean value calculation from 10 samples. The evaluation program contains patient registration and plot of the analog curve. The fact that data acquisition is handled on an interrupt basis makes it possible to monitor one patient and to accumulate data while evaluating a different recording of another patient. This system makes possible short- and long-term analysis of oxygen therapy in newborn infants.

A flexible data acquisition system was designed for an Apple IIe computer. For implementation, we used a microcomputer capable of recording 4 channels simultaneously with a selectable sample rate; this information was saved on a floppy disc and the recordings could be evaluated later. This evaluation is accomplished by reproducing the analog signals on display and calculating a histogram after deleting artefacts in the signal.

Publisher Summary This chapter describes a study to examine the clinical use of a microcomputer-assisted system for measuring transcutaneous oxygen tension in infants with bronchopulmonary dysplasia (BPD) and lung hypoplasia. Two patients with BPD were studied for several weeks during low flow oxygen therapy in a low care setting. The flow rate of the oxygen delivered through the nasal cannula was determined in order to deliver a fractional concentration of inspired oxygen of approximately 30%. Two patients with lung hypoplasia resulting from diaphragmatic hernia and atresia of the esophagus with a lung fistula were followed up for 12 months. The normal value of the transcutaneous oxygen tension and the good clinical condition were an indication to stop the low flow oxygen therapy permanently. The infant left the hospital 2 weeks later and was doing well at home. A different example of longitudinal follow-up measurements of transcutaneous oxygen tension is given. The weight increases during 12 months of an infant with hypoplasia of the left lung due to congenital herniation of the diaphragm is also shown.

The reliability of pulse oximetry and transcutaneous oxygen tension (tcPo2) was investigated in hypoxemic neonates and older infants with chronic hypoxemia due to bronchopulmonary dysplasia (BPD). It was found that during severe hypoxemia (tcPo2
