Abstract
There is an ethical obligation to relieve the pain and suffering in newborn infants. Opioids have been demonstrated to blunt the physiologic effects of pain and may prevent some of the clinical consequences of unmanaged pain. There are sufficient data to recommend the clinical use of opioid analgesics for the treatment of pain in the neonate. Neonates exposed to opioid analgesics can experience adverse effects. Adverse effects can be minimized by the use of various drug administration techniques and close monitoring. Further research is needed to determine how to optimize their effects. Data on the long-term effects of neonatal opioid exposure are warranted.

Abstract
OBJECTIVE To investigate the natural history and predictors of outcome of posthaemorrhagic ventriculomegaly in the very low birthweight (VLBW) infant. METHODS All VLBW infants admitted between September 1994 and September 1997 to the neonatal intensive care units of Brigham and Women's Hospital (Boston), Children's Hospital (Boston), and Christchurch Women's Hospital (New Zealand) with germinal matrix intraventricular haemorrhage (IVH) were identified. All charts and ultrasound scans were reviewed to define the natural history and perinatal and/or postnatal factors of value in prediction of the course of posthaemorrhagic ventriculomegaly. Progressive ventricular dilatation (PVD) was defined from the results of serial cranial ultrasound scans. RESULTS A total of 248 VLBW infants had evidence of IVH (22% of all VLBW infants, mean (SD) gestational age 26.8 (2.6) weeks). A quarter of the infants exhibited PVD. Spontaneous arrest of PVD occurred without treatment in 38% of infants with PVD. Of the remaining 62% with persistent PVD, 48% received non-surgical treatment only (pharmacological and/or drainage of cerebrospinal fluid by serial lumbar punctures), 34% received surgical treatment with insertion of a ventriculoperitoneal reservoir and/or shunt, and 18% died. The development of PVD after IVH and adverse short term outcome, such as the requirement for surgery, were predicted most strongly by the severity of IVH. CONCLUSIONS These data reflect the natural history of PVD in the 1990s and show that, despite a slight reduction in its overall incidence, there appears to be a more aggressive course, with appreciable mortality and morbidity in the extremely premature infant. The major predictor of adverse short term outcome, defined as death or need for surgical intervention, was the severity of IVH. These findings may be valuable for the management of very small premature infants.

Abstract
Neonatal/pediatric intensive care ventilators provide temporary breathing support to preterm and critically ill children who require total or partial assistance to maintain adequate ventilation. Some ventilators are specifically designed for neonatal/pediatric patients, while others--which we call all-patient ventilators--can ventilate the full range of patients from neonates to adults. We evaluated six ventilators from four suppliers: Bird, Dräger, Hamilton, and Siemens. Four of these units are all-patient models, a fifth can ventilate the range from neonatal to pediatric patients, and the sixth is suitable only for neonates. We found that the all-patient units performed at least as well as those designed specifically for neonatal/pediatric patients, and in fact all three of our Preferred units are all-patient ventilators. Unless your clinicians insist on the traditional time-cycled pressure-limited (TCPL) mode, these all-patient units are probably your best choice--and may even save costs, as we discuss in the Money Matters feature. Safe and informed ventilator use is still a vital concern. We continue to stress the importance of thoroughly understanding the characteristics and use of every ventilator model in your facility. This means not only knowing the ventilator's modes, special features, and unique characteristics, but also knowing which alarm settings are appropriate and which are not. This article includes a review of the key points of that topic.

Abstract
Radiographs are taken in the neonatal period most commonly to assist in the diagnosis and management of respiratory difficulties. Frequent accurate radiographic assessment is required and a knowledge of the radiation dose is necessary to justify such exposures. A survey of radiation doses to neonates from diagnostic radiography (chest and abdomen) has been carried out in the special care baby unit of the Royal Free Hospital. Entrance surface dose (ESD) was calculated from quality control measurements on the X-ray unit itself. Direct measurement of radiation doses was also performed using highly sensitive thermoluminescent dosemeters (TLDs) (LiF:Mg,Cu,P), calibrated and tested for consistency in sensitivity. ESD, as calculated from exposure parameters, was found to range from 28 microGy to 58 microGy, with a mean ESD per radiograph of 36+/-6 microGy averaged over 95 examinations. ESDs as derived from TLD crystals ranged from 18 microGy to 58 microGy for 30 radiographic examinations. The mean energy imparted, the mean whole body dose per radiograph and the mean effective dose were estimated to be 14+/-8 microJ, 10+/-4 microGy and 8+/-2 microSv, respectively. Assuming that neonates and fetuses are equally susceptible to carcinogenic effects of radiation, which involve an overestimation of risk, the radiation risk of childhood cancer from a single radiograph was estimated to be of the order (0.3-1.3) x 10(-6). Radiation doses compared favourably with the reference values of 80 microGy ESD published by the Commission of the European Communities in 1996, and 50 microGy published by the National Radiological Protection Board in 2000.

Abstract
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%).

Abstract
OBJECTIVE To assess the effect of moderately early postnatal dexamethasone treatment on growth and neurodevelopmental outcome in preterm infants. METHODS Thirty preterm infants enrolled in a randomised clinical trial to investigate the effectiveness of moderately early dexamethasone administration in the treatment of chronic lung disease were routinely followed up. Fifteen babies received a total dose of 4.75 mg/kg over 14 days from the 10th day of life, and 15 babies were untreated. Five infants in each group received open label steroids to facilitate extubation later in their clinical course. Growth and neurodevelopmental outcome are reported. RESULTS The mean body weight, height, and head circumference as well as the number of babies with anthropometric measurements within normal range were similar in treated and untreated babies. There was no significant difference between treated and control groups with respect to incidence of cerebral palsy, major neurosensory impairment, mean intelligence quotient scores, and behavioural abnormalities. CONCLUSIONS Postnatal dexamethasone treatment with the schedule used in this study did not impair growth and neurodevelopmental outcome in preterm infants. Data from larger trials have raised major concern that postnatal steroid treatment may increase neurodevelopmental impairment. The full extent of the risk will only be known when more trials have reported follow up data.

Abstract
OBJECTIVE This study was undertaken to determine differences in neonatal outcomes between successful pregnancies conceived immediately after a spontaneous abortion (SAB) and successful pregnancies conceived after two menstrual cycles or at least 100 days from the spontaneous abortion. STUDY DESIGN This study was a retrospective case series. Deliveries were identified from the University of California-San Francisco Perinatal Database among patients with a history of one SAB. Medical records of 268 patients were reviewed. Sixty-four patients fulfilled study criteria, with 19 in the immediate conception group and 45 in the delayed conception group. Categorical variables were analyzed using chi(2) tests and Fisher exact tests for variables with expected values of <5, whereas continuous variables were analyzed using Student t tests. RESULTS Neonatal outcomes for the 2 groups were similar, although neonates in the delayed conception group were more likely to have at least one of the following: low birth weight, an Apgar score <7 at 5 minutes, or admission to the neonatal intensive care unit. CONCLUSION In this small retrospective case series, there was no evidence of adverse neonatal outcomes associated with conception immediately after a SAB.

Abstract
Alignment and shaping of the musculoskeletal system occur during each body position that infants experience while in neonatal intensive care. Neonatal nurses and physical therapists can play a major role in designing, modeling, and teaching positioning strategies that promote skeletal integrity, postural control, and sensorimotor organization. Musculoskeletal maturation processes and adverse musculoskeletal consequences are reviewed with an emphasis on clinical implications for neonatal care, discharge teaching, and follow-up. Recommendations are offered for neonatal positioning procedures to prevent extremity malalignment, skull deformities, and gross motor delay.

Abstract
IN 1979 THE CHILDREN’ S Hospital, Denver began to address the needs of the unfortunate group of infants who exhibit evidence of poor prognosis and for whom the question is raised whether any more should be done to prolong their lives.1 This program for the NICU was based on concepts first introduced and popularized by the hospice movement.2,3 It was recognized that generally NICU staff are concerned with neonatal survival—a rescue mode of care. Staff are often ill-equipped to provide adequate care to the family of the dying infant. This program proposed a new approach to the very difficult issues involved in the care of these very sick and dying infants. The Neonatal Hospice Program was a comprehensive plan focusing on four main areas: decisionmaking process and shift to palliative care, creation of a home-like, family room setting for the infant and family, involvement of family in the dying process and hospice training for NICU staff. Over the past 20 years, elements of this program have been implemented in many NICUs. However, the adaptation of a comprehensive program for palliative neonatal care has not been universally implemented. NICU staff and families of dying infants continue to seek change in hospital practice. Catlin and Carter have undertaken important research in exploring current trends in the care for the infant from whom life support is withdrawn or withheld.

Abstract
The objective of this study is to determine the causes of asymmetry of the lateral ventricles in neonates. We also studied the effect of head position and the relationship of body weight at birth in regard to lateral ventricular size. Eligible for inclusion in this study were 60 neonatal infants whose gestational age was 33.1+/-3.5 weeks and whose birth weight was 1793+/-613 g. Ultrasonographic examinations were performed at the first and the second weeks after birth. In parasagittal and coronal scans through the posterior horn of the lateral ventricle, the lateral ventricle was traced and its area was measured. We found no significant variation of ventricular size in relation to body weight at birth. The left ventricular size was larger than the right one. The difference of the left and right ventricular sizes was partially effected by head position. The ratio of left to right lateral ventricular sizes showed a very wide distribution. We considered that ventricular asymmetry is not pathological, but due to individual differences.

Abstract
We consider the problem of record linkage in the situation where we have only non-unique identifiers, like names, sex, race etc., as common identifiers in databases to be linked. For such situations much work on probabilistic methods of record linkage can be found in the statistical literature. However, although many groups undoubtedly still use deterministic procedures, not much literature is available on deterministic strategies. Furthermore, there appears to exist almost no documentation on the comparison of results for the two strategies. In this work we compare a stepwise deterministic linkage strategy with a probabilistic strategy, as implemented in AUTOMATCH, for a situation in which the truth is known. The comparison was carried out on a linkage between medical records from the Regional Perinatal Intensive Care Centers database and educational records from the Florida Department of Education. Social security numbers, available in both databases, were used to decide the true status of each record pair after matching. Match rates and error rates for the two strategies are compared and a discussion of their similarities and differences, strengths and weaknesses is presented.

Abstract
BACKGROUND There is marked regional variation in the availability of neonatal intensive care in the United States. We conducted a study to determine whether a greater supply of neonatologists or neonatal intensive care beds is associated with lower neonatal mortality. METHODS We used the 1996 master files of the American Medical Association and the American Osteopathic Association and 1998 and 1999 surveys of neonatal intensive care units to calculate the supply of neonatologists and neonatal intensive care beds in 246 neonatal intensive care regions. We used linked birth and death records from the 1995 U.S. birth cohort to assess associations between the supply of both neonatologists and neonatal intensive care beds per capita (in quintiles) and the risk of death within the first 27 days of life. RESULTS Among 3,892,208 newborns with a birth weight of 500 g or greater, the mortality rate was 3.4 per 1000 births. After adjustment for neonatal and maternal characteristics associated with an increased risk of neonatal death, the rate was lower in the regions with 4.3 neonatologists per 10,000 births than in those with 2.7 neonatologists per 10,000 births (odds ratio for death, 0.93; 95 percent confidence interval, 0.88 to 0.99). Further increases in the number of neonatologists were not associated with greater reductions in the risk of death. There was no consistent relation between the number of neonatal intensive care beds and neonatal mortality. CONCLUSIONS A minority of regions in the United States may have inadequate neonatal intensive care resources, whereas many others may have more resources than are needed to prevent the death of high-risk newborns. The effect of the availability of neonatologists on other health outcomes is not known.

Abstract
OBJECTIVE To compare neonatal morbidity and mortality at Port Royal Maternity between 1993 and 1999 for infants with a singleton breech presentation born after 37 weeks, according to planned mode of delivery. STUDY DESIGN Retrospective study of 501 patients of whom vaginal delivery was planned in 322 (64%) or/and cesarean in 179 (36%). RESULTS Severe neonatal morbidity was similar in the two groups (13/322, 4.0% versus 8/179, 4.5%; P=0.82); severe trauma morbidity was not significantly higher in the "planned vaginal delivery" group (3/322, 0.9% versus 1/179, 0.06%; P=0.16); there were no long-term sequelae. Mortality was not higher when vaginal delivery was planned. CONCLUSION We have not found in this series any excess of morbidity or mortality attributable to vaginal delivery of breech presentations. This work does not indicate that we should change our obstetrical practice in the light of other recently-published studies.

Abstract
OBJECTIVE The aim of this study was to evaluate the role of transabdominal amnioinfusion in relieving oligohydramnios and improving pregnancy outcome. STUDY DESIGN Pregnant women with oligohydramnios amniotic fluid index (AFI<5) and premature rupture of membranes (PROM) from <27 weeks gestation were managed with serial transabdominal amnioinfusions. Under ultrasonic guidance, a 20-gauge needle was instilled in the uterine cavity and normal saline was infused until the AFI was normal. Repeat amnioinfusion was done weekly if oligohydramnios recurred. Amnioinfused cases were compared to cases with pPROM and oligohydramnios who had standard management. RESULTS The mean gestational age at first procedure was 22 weeks. The mean pre-procedure AFI was 1.1cm and post-procedure was 12 cm. The mean number of infusions was 2.4. The mean first infusion to delivery interval was 33 days. The amnioinfused group when compared to the control group had decreased perinatal mortality of 33% versus 83% (P=0.036, OR=0.4, 95% CI=0.17-0.93), neonatal mortality of 17% versus 71% (P=0.049, OR=0.26, 95% CI=0.07-0.97) and neonatal sepsis 86% versus 27%(P=0.049, OR=0.32, 95% CI=0.12-0.87) with no statistical difference in gestational age at rupture and delivery nor birthweight. Babies discharged home compared to non-survivors had a significant increase in gestational age at delivery, birthweight, NICU days and transabdominal amnioinfusions. Logistic regression showed that only transabdominal amnioinfusion and gestational age correlated with survival. CONCLUSION In selected cases of oligohydramnios with pPROM, transabdominal amnioinfusions may be associated with fluid retention and improved neonatal survival.

Abstract
Nineteen of 27 ceftazidime-resistant Enterobacter cloacae isolates from a neonatal intensive care unit in Thessaloniki, Greece, had genes coding for the novel extended-spectrum beta-lactamase IBC-1; 18 of those 19 harbored similar conjugative plasmids and belonged to two distinct genetic lineages. A synergy test with ceftazidime and imipenem enabled us to identify five unrelated bla(IBC-1)-carrying E. cloacae isolates from other wards of the hospital. It seems that this integron-associated gene is capable of dispersing both by clonal spread and by gene dissemination.

Abstract
OBJECTIVE To compare the measurement of haemoglobin concentration ([Hb]) using the HemoCue haemoglobinometer with that using the Coulter STKS haemoglobinometer. DESIGN Thirty two EDTA samples were taken from neonates. [Hb] was measured in these samples using the HemoCue; the samples were then transferred to the haematology laboratory for [Hb] determination with the Coulter STKS. In addition, [Hb] was determined in 50 different random EDTA neonatal samples already held in the laboratory, using the HemoCue and Coulter STKS. PATIENTS Neonates in the intensive care and low dependency Units of the Royal Devon and Exeter Hospital. INTERVENTIONS Samples were collected from arterial lines or by venepuncture or heel prick into an EDTA bottle. MAIN OUTCOME MEASURES [Hb] using the HemoCue and Coulter STKS methods. RESULTS The mean [Hb] measured using the HemoCue was 150.3 g/l (range 78-215) compared with 152.8 g/l (range 78-217) measured using the Coulter STKS, with a mean of the differences of 2.5 g/l. The standard deviation of the differences of the 82 samples was 3.73 g/l. The limits of agreement of the two methods (mean difference +/- 2SD) were -4.8 to +9.8 g/l. CONCLUSION With adequate training and monitoring, the HemoCue can be used directly on the neonatal unit for rapid determination of [Hb] to within 7.5 g/l compared with the laboratory Coulter STKS, using much smaller sample volumes.

Abstract
The Alagille syndrome (AGS) is a multisystem autosomal dominant condition. In this case report, we describe a pregnant woman with this unusual disorder, in whom serial fetal sonography revealed severe pulmonary stenosis and progressively severe intrauterine growth retardation, suggesting that the fetus also had AGS, a diagnosis which was confirmed postnatally. In this report, the potential complications for pregnancy, labor and delivery when both mother and fetus are affected with AGS are described.

Abstract
OBJECTIVE To describe the magnetic resonance imaging (MRI) characteristics of punctate brain lesions in neonates (number, appearance, distribution, and association with other brain abnormalities) and to relate them to neurodevelopmental outcome. METHODS A retrospective analysis was performed of 110 MRI brain scans from 92 infants admitted in 1998 to the neonatal intensive care unit. Results of routine neurodevelopmental follow up (1998-2001) in those infants with punctate brain lesions were analysed. RESULTS Punctate lesions were observed in 15/50 preterm and 2/42 term infants. In the preterm group, the number of lesions was < 3 in 20%, 3-10 in 27%, and > 10 in 53%. In 14/15 the lesions were linearly organised and located in the centrum semiovale. Other brain abnormalities were absent or minor--that is, "isolated" punctate lesions--in 8/15 and major in 7/15. In the term group, punctate lesions were organised in clusters and no other brain abnormalities were observed. Isolated punctate lesions were observed in 10/17 infants, and a normal neurodevelopmental outcome was seen in 9/10 (mean follow up 29.5 months). One infant showed a slight delay in language development. In the infants with associated brain lesions (7/17, mean follow up 27.5 months), outcome was normal in only two subjects. CONCLUSIONS Punctate lesions are predominantly seen in preterm infants, are usually linearly organised, and border the lateral ventricles. Isolated punctate lesions may imply a good prognosis, because most of these subjects have a normal neurodevelopmental outcome so far.

Abstract
OBJECTIVES The aim of this study was to describe the intensive care unit neonatologists' attitudes about a neonate with terminal or pre-terminal renal failure. METHODS A questionnaire was sent to all French neonatal intensive care units. Physicians were asked to describe their attitude about neonatal chronic renal failure (Would you agree with dialysis and graft for these children?). Physicians were also presented with two clinical observations involving neonates with varying degrees of renal insufficiency and a complicating comorbidity, including neurological abnormality or socioeconomic circumstances. RESULTS Responses were obtained from 92% of the university neonatal care units. The will to take care of a neonate with end-stage renal failure till the renal graft, varied greatly from a centre to another one. Three (9%) university-teams said they had a strong will to bring the baby from the neonatal period to the time of renal graft. Eleven other centres (32%) did not have any will for accompanying the baby till the renal graft. Eight centres (24%) would be rather favourable to the idea of dialysis and graft, and 12 others (35%) would be rather unfavourable. CONCLUSION The results of this study show great differences between French neonatologists when they are faced to newborns with end stage renal failure. Ethical, medical and organisational difficulties are matters of controversy. The epidemiological impact of the perinatal discussion could be a 20% variation of all the renal grafts in children.

Abstract
Cerebral palsy is a non-progressive disorder of the developing brain with different etiologies in the pre-, peri- or postnatal period. The most important of these diseases is cystic periventricular leukomalacia (PVL), followed by intra- and periventricular hemorrhage, hypoxic-ischemic encephalopathy, vascular disorders, infections or brain malformations. The underlying cause is always a damage of the first motor neuron. Prevalence of cerebral palsy in Europe is 2-3 per 1000 live births with a broad spectrum in different birth weight groups. Our own data concerning only pre-term infants in the NICU with birth weight below 1500 g (VLBW) are between 10%-20%. Established classical treatment methods include physiotherapy (Bobath, Vojta, Hippotherapy), methods of speech and occupational therapists (Castillo-Morales, Sensory Integration) and other therapeutical concepts (Petö, Affolter, Frostig).

Abstract
Neonatal cholestasis must always be considered in a newborn who is jaundiced for more than 14-21 days and a measurement of the serum total and conjugated bilirubin in these infants is mandatory. Conjugated hyperbilirubinaemia, dark urine and pale stools are pathognomic of the neonatal hepatitis syndrome which should be investigated urgently. The neonatal hepatitis syndrome has many causes and should be investigated using a structured protocol. The most important condition in the differential diagnosis is biliary atresia and affected infants require a Kasai portoenterostomy performed by an experienced surgeon, ideally before the infant is 60 days old. A modified evaluation schedule should be used for preterm infants who have required neonatal intensive care. Genetic causes of the neonatal hepatitis syndrome are increasingly recognized and early diagnosis facilitates genetic counselling and, in some situations, specific treatment. The management of cholestasis is largely supportive, consisting of aggressive nutritional support with particular attention to fat-soluble vitamin status. The use of ursodeoxycholic acid is associated with improvement in biochemical measures of cholestasis and may improve the natural history of cholestasis in some circumstances. Outcome is dependent on aetiology. In idiopathic neonatal hepatitis more than 90% make a complete biochemical and d clinical recovery.
