Gastrointestinal malformations: impact of prenatal diagnosis on gestational age at birth.

The aim of the study was to analyse the degree to which gestational age (GA) has been shortened due to prenatal diagnosis of gastrointestinal malformations (GIM). The data source for the study was 14 population-based registries of congenital malformations (EUROCAT). All liveborn infants with GIMs and without chromosomal anomalies, born 1997-2002, were included. The 14 registries identified 1047 liveborn infants with one or more GIMs (oesophageal atresia, duodenal atresia, omphalocele, gastroschisis and diaphragmatic hernia). Median GA at birth was lower in prenatally diagnosed cases for all five malformations, although not statistically significant for gastroschisis. There was little difference in median birthweight by GA for the pre- and postnatally diagnosed infants. The difference in GA at birth between prenatally and postnatally diagnosed infants with GIMs is enough to increase the risk of mortality for the prenatally diagnosed infants. Clinicians need to balance the risk of early delivery against the benefits of clinical convenience when making case management decisions after prenatal diagnosis. Very few studies have been able to show benefits of prenatal diagnosis of congenital malformations for liveborn infants. This may be because the benefits of prenatal diagnosis are outweighed by the problems arising from a lower GA at birth.

Validation française d'un questionnaire de stress post-traumatique destiné aux parents d'enfants présentant un risque périnatal élevé = French validation of the "Perinatal PTSD Questionnaire" assessing parent's posttraumatic stress reactions following the birth of a high risk infant.

(from the journal abstract) Objectives: The birth of a high risk infant--such as a very or extremely premature infant--can represent an important traumatic experience for parents. R. DeMier, M. Hynan et al's "Perinatal PTSD Questionnaire" aims at exploring, retrospectively, parent's posttraumatic stress reactions following the birth of a high risk infant. This paper describes the French validation of this questionnaire. Methods: Fifty-two families with a very or extremely premature infant and 25 families with a full term infant responded to the "Perinatal PTSD Questionnaire" and the "Impact of Event Scale" when children were 18 months old. Results: Parents of high risk infants can present posttraumatic stress reactions such as intrusion, avoidance or arousal symptoms. The French version of the "Perinatal PTSD Questionnaire" has satisfactory psychometric properties. Conclusions: As posttraumatic reactions are not directly related to objective descriptions of the stressful event, it may be essential to the liaison child psychiatrist to consider individual posttraumatic reactions in order to optimise preventive intervention with the parents. A questionnaire should not replace a clinical interview, however it may represent a useful screening tool. Also, this questionnaire should be useful for research purposes.

Influence d'une hospitalisation prénatale sur les facteurs de stress parentaux lors d'une naissance prématurée [Influence of prenatal hospitalization on parental stressful experience in the case of a premature birth].

OBJECTIVES: To investigate the influence of prenatal hospitalization before a premature birth, on the parental stressful experience, parental symptoms of post-traumatic stress and quality of parent-infant interaction during the hospitalization in neonatology. POPULATION AND METHODS: Population: 51 preterm infants born and 25 full term infants control. Four groups: controls, premature without prenatal hospitalization, premature with a short (<8 days) prenatal hospitalization and premature with a long (≥8 days) prenatal hospitalization. Instruments: the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS: NICU, Miles et al., 1993 [14]) and the Perinatal PTSD Questionnaire (PPQ, Quinnell and Hynan, 1999 [16]). RESULTS: When prenatal hospitalization of the mother occurred, parents acknowledged increased stress induced by the environmental factors during the infant's hospitalization. Furthermore, mothers from the group with a short prenatal hospitalization presented significantly more symptoms of post-traumatic stress. Parents presenting more symptoms of post-traumatic stress describe a significantly more difficult interaction with their infant in neonatology. CONCLUSION: This study highlights the necessity to deliver special care to women hospitalized shortly (<8 days) prior to the delivery of their premature baby. This group is at high risk of presenting post-traumatic stress symptoms, which could have a negative impact on the quality of parent-infant interactions.

Factors associated with the quality of prenatal care: an approach to premature birth

OBJECTIVETo assess the quality of prenatal care in mothers with premature and term births and identify maternal and gestational factors associated with inadequate prenatal care.METHODCross-sectional study collecting data with the pregnant card, hospital records and interviews with mothers living in Maringa-PR. Data were collected from 576 mothers and their born alive infants who were attended in the public service from October 2013 to February 2014, using three different evaluation criteria. The association of prenatal care quality with prematurity was performed by univariate analysis and occurred only at Kessner criteria (CI=1.79;8.02).RESULTSThe indicators that contributed most to the inadequacy of prenatal care were tests of hemoglobin, urine, and fetal presentation. After logistic regression analysis, maternal and gestational variables associated to inadequate prenatal care were combined prenatal (CI=2.93;11.09), non-white skin color (CI=1.11;2.51); unplanned pregnancy (CI=1.34;3.17) and multiparity (CI=1.17;4.03).CONCLUSIONPrenatal care must follow the minimum recommended protocols, more attention is required to black and brown women, multiparous and with unplanned pregnancies to prevent preterm birth and maternal and child morbimortality.

Mother's attachment representations of their premature infant at 6 and 18 months after birth.

The effects of premature birth on attachment have generally been examined from the infant's perspective. There is a lack of data concerning parental attachment representations toward a premature child. Because of the psychological stress engendered in parents confronted with a premature birth, we hypothesized that their attachment representations would be altered during the first months after the hospital discharge. Fifty families with a premature infant (25-33 gestation weeks) and a control group of 30 families with a full-term infant participated to the study. Perinatal risks were evaluated during hospitalization. To assess mothers' representations of their infant, the Working Model of the Child Interview (WMCI, Zeanah & Benoit, 1995 & Benoit, Zeanah, Parker, Nicholson, & Coolbear, 1997) were administered when their children were 6 and 18 months old. The severity of the perinatal risks was found to have an impact on the mothers' attachment representations. At six months, only 20% of the mothers of a prematurely born infant (30% at 18 months) had secure attachment representations, vs. 53% for the control group (57% at 18 months). Furthermore, mothers of low-risk premature infants more often had disengaged representations, whereas distorted representations were more frequent in the high-risk group of premature children. These findings suggest that the parental response to a premature birth is linked to the severity of postnatal risks. The fact that secure attachment representations are affected in mothers of low-risk infants just as much as they are in mothers of high-risk infants points to the need to conduct further studies aimed at evaluating whether preventive intervention for both low-risk and high-risk premature will be helpful.

Energetic and metabolic cost of growth in Gambian infants.

The aim of the study was to measure the energy used for growth of healthy fullterm and breast-fed Gambian infants. The weight gain (WG) of 14 infants (mean age +/- SEM 17 +/- 1 d, weight 3.581 +/- 0.105 kg) was measured over a 2-week period; the energy intake (EI) from breast milk was assessed for 24 h in the middle of the study period by weighing the infant before and after each breast-feed. On the same day, sleeping energy expenditure (SEE) and respiratory quotient (RQ) were measured for 30 min on five occasions through the 24-h period. EI averaged 502 +/- 25 kJ/kg.d, and SEE 230 +/- 6 kJ/kg.d; thus, an average of 272 kJ/kg.d were available for physical activity and the energy stored for growth. The total energy spent by infants while sleeping and for periods of physical activity was calculated to be 1.7 x SEE. The mean RQ measured on five occasions averaged 0.879 +/- 0.009. SEE was correlated with WG (r = 0.747, P less than 0.005), with a slope of the regression line of 5.5 kJ/g; this value can be considered as an estimate of the energy spent for new tissue synthesis in the resting infant. The efficiency of weight gain was lower in this study (67%) than in studies conducted on fast-growing preterm infants or children recovering from malnutrition.

Effects of perinatal stress and maternal traumatic stress on the cortisol regulation of preterm infants.

Preterm infants experience intense stress during the perinatal period because they endure painful and intense medical procedures. Repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis during this period may have long-term effects on subsequent cortisol regulation. A premature delivery may also be intensely stressful for the parents, and they may develop symptoms of posttraumatic stress disorder (PTSD). Usable saliva samples were collected (4 times per day over 2 days, in the morning at awakening, at midday, in the afternoon, and in the evening before going to bed) to assess the diurnal cortisol regulation from 46 preterm infants when the infants were 12 months of corrected age (∼ 14 months after birth). Mothers reported their level of PTSD symptoms. The results showed an interaction between perinatal stress and maternal traumatic stress on the diurnal cortisol slope of preterm infants (R(2) = .32). This suggests that the HPA axis of preterm infants exposed to high perinatal stress may be more sensitive to subsequent environmental stress.

Parental post-traumatic reactions after premature birth: implications for sleeping and eating problems in the infant.

BACKGROUND: Progress in perinatal medicine has made it possible to increase the survival of very or extremely low birthweight infants. Developmental outcomes of surviving preterm infants have been analysed at the paediatric, neurological, cognitive, and behavioural levels, and a series of perinatal and environmental risk factors have been identified. The threat to the child's survival and invasive medical procedures can be very traumatic for the parents. Few empirical reports have considered post-traumatic stress reactions of the parents as a possible variable affecting a child's outcome. Some studies have described sleeping and eating problems as related to prematurity; these problems are especially critical for the parents. OBJECTIVE: To examine the effects of post-traumatic reactions of the parents on sleeping and eating problems of the children. DESIGN: Fifty families with a premature infant (25-33 gestation weeks) and a control group of 25 families with a full term infant participated in the study. Perinatal risks were evaluated during the hospital stay. Mothers and fathers were interviewed when their children were 18 months old about the child's problems and filled in a perinatal post-traumatic stress disorder questionnaire (PPQ). RESULTS: The severity of the perinatal risks only partly predicts a child's problems. Independently of the perinatal risks, the intensity of the post-traumatic reactions of the parents is an important predictor of these problems. CONCLUSIONS: These findings suggest that the parental response to premature birth mediates the risks of later adverse outcomes. Preventive intervention should be promoted.

Survival and health in liveborn infants with transposition of great arteries--a population-based study.

OBJECTIVE: To describe treatment, survival, and morbidity for liveborn infants with isolated transposition of great arteries (TGA). DESIGN: Population-based data from 7 European registries of congenital malformations (EUROCAT). RESULTS: Ninety-seven infants were diagnosed with isolated TGA and livebirth prevalence was 2.0 per 10,000 livebirths. The majority of infants were treated with prostaglandins (83%) and 57% had a catheter atrial septostomia performed. Arterial switch surgery was performed in 78 infants, other or unknown type of surgery was performed in 3 cases, and for 6 infants there was no information on surgery. At 1 year of age 69 infants were alive (71%) and 24 (25%) were dead (4 unknown). There were 10 deaths before surgery and 58% of all deaths took place during the first week. There was no statistically significant regional difference in mortality. Eight infants diagnosed prenatally all survived to 1 year and only 71% of infants diagnosed after birth survived (P = 0.08). Data on morbidity at 1 year of age was available for 57 infants. Fifty-one infants were reported with normal health and development. CONCLUSIONS: In this population-based study survival for liveborn infants with TGA is lower than in studies published from tertiary centers. Outcome for survivors at 1 year of age seems favorable.

Feasibility of non-invasive pressure support ventilation in infants with respiratory failure after extubation: a pilot study.

OBJECTIVE: To evaluate the feasibility and effects of non-invasive pressure support ventilation (NIV) on the breathing pattern in infants developing respiratory failure after extubation. DESIGN: Prospective pilot clinical study; each patient served as their own control. SETTING: A nine-bed paediatric intensive care unit of a tertiary university hospital. PATIENTS: Six patients (median age 5 months, range 0.5-7 months; median weight 4.2 kg, range 3.8-5.1 kg) who developed respiratory failure after extubation. INTERVENTIONS: After a period of spontaneous breathing (SB), children who developed respiratory failure were treated with NIV. MEASUREMENTS AND RESULTS: Measurements included clinical dyspnoea score (DS), blood gases and oesophageal pressure recordings, which were analysed for respiratory rate (RR), oesophageal inspiratory pressure swing (dPes) and oesophageal pressure-time product (PTPes). All data were collected during both periods (SB and NIV). When comparing NIV with SB, DS was reduced by 44% (P < 0.001), RR by 32% (P < 0.001), dPes by 45% (P < 0.01) and PTPes by 57% (P < 0.001). A non-significant trend for decrease in PaCO(2) was observed. CONCLUSION: In these infants, non-invasive pressure support ventilation with turbine flow generator induced a reduction of breathing frequency, dPes and PTPes, indicating reduced load of the inspiratory muscles. NIV can be used with some benefits in infants with respiratory failure after extubation.

Carotid-subclavian arteries Index (CSI), a new echocardiographic index to recognize coarctation of the aorta in neonates and infants

Introduction: Coarctation of the aorta is a common congenital heart malformation. Mode of diagnosis changed from clinically to almost exclusively by echocardiogram and MRI. We claim to find a new echocardiographic index, based on simple and reliable morphologic measurements, to facilitate the diagnosis of aortic coarctation in the newborn.We reproduce the same procedure for older child to validate this new index. Material and Methods: We reviewed echocardiographic studies of 47 neonates with diagnosis of coarctation who underwent cardiac surgery between January 1997 and February 2003 and compared them with a matched control group. We measured 12 different sites of the aorta, aortic arch and the great vessels on the echocardiographic bands. In a second time we reviewed 23 infants for the same measurements and compare them with a matched control group. Results: 47 neonates with coarctation were analysed, age 11.8 _ 10 days,weight 3.0 _ 0.6 kg, body surface 0.20 _ 0.02m2. The control group was of 16 newborns aged 15.8 _ 10 days,weight 3.2 _ 0.9 kg and body surface 0.20 _ 0.04m2. A significant difference was noted in many morphologic measurement between the both groups, the most significant being the distance between the left carotid artery and the left subclavian artery (coarctation vs control: 7.3 _ 3mm vs 2.4 _ 0.8mm, p _ 0.0001). We then defined a new index, the carotid-subclavian arteries index (CSI) as the diameter of the distal tranverse aortic arch divided to the distance left carotid artery to left subclavian artery being also significaly different (coarctation vs control: 0.76 _ 0.86 vs 2.95 _ 1.24, p _ 0.0001). With the cutoff value of this index of 1.5 the sensitivity for aortic coarctation was 98% and the specificity of 92%. In an older group of infant with coarctation (16 patients) we apply the same principle and find for a cut-off value of 1.5 a sensitivity of 95% and a specificity of 100%. Conclusions: The CSI allows to evaluate newborns and infants for aortic coarctation with simple morphologic measurement that are not depending of the left ventricular function, presence of a patent ductus arteriosus or not. Further aggressive evaluation of these patient with a CSI _ 1.5 is indicated.

Surgical treatment of temporoparietooccipital cortical dysplasia in infants: report of two cases.

PURPOSE: Extensive multilobar cortical dysplasia in infants commonly is first seen with catastrophic epilepsy and poses a therapeutic challenge with respect to control of epilepsy, brain development, and psychosocial outcome. Experience with surgical treatment of these lesions is limited, often not very encouraging, and holds a higher operative risk when compared with that in older children and adults. METHODS: Two infants were evaluated for surgical control of catastrophic epilepsy present since birth, along with a significant psychomotor developmental delay. Magnetic resonance imaging showed multilobar cortical dysplasia (temporoparietooccipital) with a good electroclinical correlation. They were treated with a temporal lobectomy and posterior (parietooccipital) disconnection. RESULTS: Both infants had excellent postoperative recovery and at follow-up (1.5 and 3.5 years) evaluation had total control of seizures with a definite "catch up" in their development, both motor and cognitive. No long-term complications have been detected to date. CONCLUSIONS: The incorporation of disconnective techniques in the surgery for extensive multilobar cortical dysplasia in infants has made it possible to achieve excellent seizure results by maximizing the extent of surgical treatment to include the entire epileptogenic zone. These techniques decrease perioperative morbidity, and we believe would decrease the potential for the development of long-term complications associated with large brain excisions.

Energy balance, physical activity, and thermogenic effect of feeding in premature infants.

In order to assess the contribution of the thermogenic effect of feeding and muscular activity to total energy expenditure, nine premature infants were studied for 2 consecutive days during which time repeated measurements of energy expenditure by indirect calorimetry were performed throughout the day, combined with a visual activity score based on body movement. The infants were growing at 16.6 +/- 4.0 g/kg/day (mean +/- SD) and received 110 +/- 8 kcal/kg/day metabolizable energy (milk formula) and 522 +/- 40 mgN/kg/day. Their total energy expenditure was 68 +/- 4 kcal/kg/day indicating that 41 +/- 7 kcal/kg/day was retained for growth. Based on the combination of energy + N balances it was estimated that 80% of the weight gain was fat-free tissue and 20% was fat tissue. The rate of energy expenditure measured minute-by-minute was significantly and linearly correlated with the activity score in both the premeal (r = 0.75;p less than 0.001) and the postmeal periods (r = 0.74; p less than 0.001) with no difference in the regression slope, but with a significant difference in intercept. In preset feeding schedules the latter allowed an estimation of the thermogenic effect without the confounding effect of activity. This was found to be 3.1 +/- 1.8% when expressed as a percentage of metabolizable energy intake. However when the "classical" approach was used as a comparison (integration of extra energy expenditure induced by the meal), the thermogenic effect was found to be greater, i.e. 9.5 +/- 3.8% of the meal's metabolizable energy, due to the superimposed effect of physical activity in the postprandial state.(ABSTRACT TRUNCATED AT 250 WORDS)
