Abstract
BACKGROUND Cystic adenomatoid malformation, a rare pulmonary malformation, usually appears as a cystic mass, radiologically. It may be infected and confusion has also arisen in distinguishing it from pneumonia with pneumatoceles. CASE REPORTS A full-term boy suffered from severe neonatal respiratory distress. Pregnancy had been uneventful despite the fact that his mother had insulin-dependent diabetes. Prenatal ultrasonographies did not reveal any abnormality. On day 2, X-rays showed a right pulmonary mass that appeared solid. The patient was treated for E Coli sepsis. Subsequently, the pulmonary mass became lacent, cystic, fluid-filled, resembling an abscess; the CT scan confirmed these features. As the lesion increased in volume, a limited resection was performed. Histologic examination showed adenomatoid proliferation of bronchiolar elements with formation of cysts and necrosis. CONCLUSION Infection of cystic adenomatoid malformation may supervene the first days of life resulting in a lung abscess appearance.

Abstract
OBJECTIVE To describe the pharmacokinetics of midazolam, a water-soluble benzodiazepine with a short half-life, in critically ill neonates. HYPOTHESIS Midazolam clearance is reduced in neonates compared with clearance in children, and the doses currently in use, which are derived from pediatric studies, are excessive. PATIENTS AND METHODS This population study was conducted in 187 neonates requiring intravenous sedation for artificial ventilation. The 531 midazolam concentration measurements obtained were analyzed by use of NONMEM and a two-compartment model with four parameters: clearance (CL), central volume (Vc), peripheral volume (Vp), and intercompartmental clearance (Q). The influence of birth weight (range, 700 to 5200 gm), gestational age (range, 26 to 42 weeks), postnatal age (range, 0 to 10 days), and comedications were investigated. RESULTS CL and Vc (mean +/- SE) were found to be directly proportional to birth weight (CL = 0.070 +/- 0.013 L/kg/hr; VC = 0.591 +/- 0.065 L/kg). The CL was 1.6 times higher in neonates with a gestational age of more than 39 weeks. It was 0.7 times lower in neonates receiving inotropic support. The postnatal age had no apparent effect on midazolam kinetics. The Vp and Q (mean +/- SE; 0.42 +/- 0.11 L and 0.29 +/- 0.08 L/hr, respectively) were not influenced by any of the covariates studied. There was a large interindividual variability for the pharmacokinetic parameters. CONCLUSION The mean midazolam doses required for critically ill neonates are lower than those required for older infants.

Abstract
BACKGROUND Assessing pain in premature babies is difficult because of their limited capacities to communicate. The aim of this study was to recognize manifestations of acute and chronic pain or, on the contrary, of well-being state, and to validate a "pain scale" for premature babies. POPULATION AND METHODS Premature babies less than 28 days of age (most of them less than 32 weeks of gestational age) were carefully observed during their stay in a neonatal intensive care unit by nurses, physicians, physiotherapists and a psychiatrist. All signs and symptoms were collected during situations a priori painful and compared to the behavior of the well-being states. Photographs and videofilms were also analysed. RESULTS Five items, scored from 0 to 4, were established, based on facial activity, movements and posture of the body, quality of sleep, relationship with the examiner, and efficacy of measures of comforting. These items permitted to describe four patterns corresponding to 1: well-being status, 2: acute pain, 3 and 4: durable pain or discomfort either through clinical picture of irritability or motionlessness. A strict concordance of scores for the five items between the different examiners was found in 80% of the 50 babies studied. The sensibility of the scale (studied in 12 babies) appeared accurate (77% of variation of the scores during hospitalization). CONCLUSIONS An objective assessment of pain and discomfort in premature babies can be made using a "pain scale" useful for care and therapeutic decisions.

Abstract
BACKGROUND Periventricular leukomalacia in preterm neonates is usually due to abnormal cerebral blood flow before and/or during delivery. It is diagnosed during the first month of life. This study describes a case of late-developing periventricular leukomalacia. CASE REPORT A girl was delivered by cesarean section at the 23rd week of gestation that was complicated by placenta previa. She weighted 880 g and immediately required resuscitation. She did not develop respiratory distress syndrome. She was intubated and ventilated for the first two weeks of life and developed bronchopulmonary dysplasia requiring corticosteroid treatment. Extubation was possible on day 43. The neonate had been given antibiotics for the first 10 days of life and indomethacin on day 8 because of a patent ductus arteriosus. Repeated craniosonography showed moderate bilateral intraventricular hemorrhage and occipital areas of hyperechogenicity that disappeared at the end of the first month of life. Repeated electroencephalograms revealed no positive rolandic sharp waves until the infant was 42 days old. Craniosonography on day 48 showed areas of heterogeneous hyperechogenicity and NMR imaging showed bilateral frontoparietal leukomalacia with loss of white matter. The baby died on day 71. CONCLUSIONS Late periventricular leukomalacia is exceptional and usually seen after postnatal abnormalities in cerebral blood flow and/or prolonged hypoxemia. Both these risk factors were absent in this patient.

Abstract
During the neonatal period, total and conjugated bilirubin determinations are necessary to identify the origin of jaundice, to predict its evolution and to treat it. We discuss the results obtained in 108 neonates (less than 15 days old), undergoing phototherapy or not, using a colorimetric diazo reaction and dual wavelength reflectance with a Kodak Ektachem analyzer. Concerning total bilirubin determination, the methods correlate well (r > 0.96). Discrepancies are observed for conjugated or "direct" bilirubin, and high performance liquid chromatography was carried out in order to explain them. The chromatograms show 4 neonate samples with only classic mono- but no di-glucurono-conjugate fractions, whereas all the neonates present two unusual fractions (I and II) not seen in adults. A correlation was found between the amount of fraction II and the conjugated bilirubin determined by diazo reaction and between fraction I and the conjugated bilirubin obtained in the Kodak Ektachem assay. A better correlation between fraction I and conjugated bilirubin on Kodak was observed (r = 0.79, vs r = 0.66) when the newborns were submitted to phototherapy. Moreover, fraction II and conjugated bilirubin measured by the diazo reaction on Hitachi 717 rose significantly. In conclusion, total bilirubin is accurately determined during the neonatal period; for conjugated or "direct" bilirubin determination, our study points out significant differences. Further investigation will determine the nature of the fractions observed by liquid chromatography in neonatal sera, and the components actually determined by the automatized methods usually employed.

Abstract
PATIENTS AND METHODS All cases of sudden and unexpected death occurring in maternity were studied over a period of 6 years (1985-1991). Anamnestic data, results of clinical examination of the body and findings of bacterial screening of body fluids or tissues were collected. The results at necropsy were also collected following the protocol used, with parental consent, in all cases of sudden infant death syndrome. RESULTS There were 31 cases of sudden and unexpected death. Of these, 48% occurred before the 24th hour of life, 68% before the 36th hour and 84% before the 72nd hour. The majority of death occurred at night (55% between midnight and 6 AM, 90% between 9 PM and 9 AM). Analysis of the data provided a precise cause of death in 25 cases (81%), and a probable cause in 4 cases (13%). The major causes were perinatal anoxia, generally associated with massive amniotic inhalation (16 cases), and maternal-fetal infection (9 cases). No cause was found in 2 cases. Despite the fact that the death occurred unexpectedly, half of the newborns showed warning signs, some hours before the event. These signs were either not detected or ignored. CONCLUSION The incidence of sudden death in neonates is 0.15 to 0.36/1,000 live births. Its causes are generally correlated with common neonatal diseases. Its occurrence at night and the existence of warning signs raise questions concerning the care of neonates in maternity.

Abstract
The accuracy of the Radiometer OSM3 oxymeter for measurement of fetal haemoglobin (HbF) in infants was investigated, and compared to one of the standard reference methods using alkali electrophoresis of haemoglobin. Blood samples of 37 infants with different gestational (27-41 weeks) and postnatal (1-198 days) ages were analysed. The two methods gave very close results but a significant mean difference (range -4.5-16.5%). However, agreement between the two methods was judged clinically acceptable (95% limits of agreement -7.5-15.5%). A rapid determination of HbF percentage, using OSM3, is an important determinant for correct assessment of oxygen saturation in newborn infants in intensive care units.

Abstract
Mycoplasma hominis and Ureaplasma urealyticum were cultured and counted in the gastric fluid of 153 neonates divided into three groups: 28 preterm neonates managed in an intensive care unit (Group I); 83 full term neonates with suspected infection (Group II); and 42 full term neonates with no evidence of infection (Group III). The colonization rate (17.85%) in the intensive care unit group was not significantly different from the rates seen in the two other groups. These results do not militate against the pathogenic role of the two organisms studied but rather suggest a contributory role of other factors.

Abstract
The effectiveness of intravenously administered immunoglobulin (Ig) therapy for prophylaxis of infection was evaluated in high-risk preterm infants. Two hundred thirty-five premature newborns were randomly assigned, in a double-blind controlled trial, to treatment and placebo groups. Thirty-five infants (29%) of the Ig group and 29 (25%) of the placebo group had one or more episodes of certain infection. Thirty infants (25%) of the Ig group and 18 (16%) of the placebo group had one or more episodes of probable infection. No significant differences were observed in the incidence of certain or probable infection in treated and control infants. Nevertheless, among the infants who had one or more certain or probable episodes of infection, more of them belonged to the Ig group than to the placebo group. The possible deleterious effect of the administration of large amounts of polyspecific Ig is discussed.

Abstract
The new preparations of intravenously administered intact immunoglobulins have revived the interest of paediatricians in these products for the treatment and prevention of infections in neonates. Experimental animal studies and clinical trials have given equivocal results. In the treatment of neonatal infections, immunoglobulins are probably effective when they are given soon after the onset of the infection and above all provided that the preparation administered contains specific antibodies in sufficient amounts. As regards the prevention of infections in neonates at risk, and particularly in premature infants, the multicentre clinical trials carried out so far have given conflicting results, so that it cannot be concluded that the systematic administration of immunoglobulins to these populations is unquestionably effective. These insufficient results are probably due to the lack of specificity of polyvalent immunoglobulins.

Abstract
Bronchopulmonary dysplasia (BPD) has become a frequent and worrying issue in neonatal intensive care units (NICU). The aim of this retrospective study was to define more precisely the incidence of BPD within a population of 2,216 newborns admitted at less than 24 hrs of life. 138 cases of BPD were diagnosed. The BPD rates decrease exponentially with regard to gestational ages (GA) [67% at less than 28 weeks (w), 37% at 28-29 w, 22% at 30 w, 9% at 31-32 w, 3% at 33-34 w and 0.4% at greater than or equal to 35 w]. The presence of hyaline membrane disease (HMD) increases the GA related risks by 1.5, 2, 3, 10, 20 and 40 times at less than 28 w, 28-29 w, 30 w, 31-32 w, 33-34 w and greater than or equal to 35 w, respectively. Other factors such as interstitial emphysema, refractory hypoxemia and hypotrophy associated with HMD, have been found associated with increased risks. A chart taking into account all these parameters has been constructed allowing the determination of individual risks of developing BPD during the first days of life.

Abstract
Phospholipid analysis of tracheal aspirates obtained from 37 newborn infants, all intubated for respiratory diseases, was performed in order to compare infants having hyaline membrane disease (HMD) (n = 11), to those presenting with transient tachypnoea (TT) (n = 16) or another respiratory disorder (n = 10) and to determine if distinguishing features could be discovered for HMD or TT. In the HMD group, a significantly lower amount (about 20%) of recoverable phospholipid material was observed. Furthermore, the groups differed in their phospholipid profile: infants with HMD presented with a deficiency in saturated phosphatidylcholine, but had a related increase in unsaturated phosphatidylcholine, and an increased proportion of phosphatidylethanolamine (about 2.5 times more) as compared with both other groups. In infants suffering HMD and TT, phosphatidylglycerol was lower and phosphatidylinositol was higher than in infants with other diseases. This change was the only one displayed in infants with TT. We speculate that the observed changes reflect changes in amount and composition of surfactant and are involved in the etiology of HMD and TT.

Abstract
A premature infant had three episodes of enterocolitis-like symptoms during the first three months of life. Brucella melitensis was isolated in a prolonged blood culture on day 85. The clinical manifestations disappeared under treatment and did not recur. A maternofetal transmission is suggested in this case. The importance of prolonged blood cultures when brucellosis is epidemiologically suspected is emphasized.

Abstract
Transcutaneous PO2 (PTCO2) (Radiometer electrode heated to 44 degrees C) was compared to arterial PO2 (PaO2) in 19 infants with bronchopulmonary dysplasia: 12 infants were tested once, at the mean postnatal age of 14 weeks (range 4-43 weeks), the other 7 infants were studied longitudinally from 5 weeks (range 2-8 weeks) to 12 weeks (range 6-18 weeks) of postnatal age. The protocol was standardized: measurement during behavioral stage 1, using a peripheral arterial line. Twenty-eight comparisons between PTCO2 and PaO2 were obtained. PTCO2 was significantly related to PaO2 [PTCO2 (mmHg) = 0.81 PaO2 + 5.2, r = 0.73, p less than 0.01]. The mean difference PTCO2 - PaO2 was -7.2 mmHg (range: -34.5 to + 33); in the studied age range the PTCO2 - PaO2 was not significantly related to postnatal age (r = -0.24; p greater than 0.1).

Abstract
A proper organization has been set up at Antoine-Béclère's hospital in order to study the infants who died suddenly. Between July 1985 and July 1987, 69 cases (10 babies less than 1 week of age) were admitted. The purpose of this work was, for the 59 sudden deaths of infants aged more than 1 week (35 males, 24 females), to present the results of a definite protocol of investigation (past history, clinical examination, laboratory and pathological data) for determining either the etiology or the mechanism of these deaths. A thorough investigation was performed in 45/52 cases (no autopsy in 7 cases). A definite diagnosis was possible in 38/45: 13 viral infections, 5 gastro-esophageal reflux, 13 viral infections associated with reflux, 9 with an additional event (massive alimentary inhalation, slipping under blankets, major hyperthermia) to either a viral infection or a reflux, 1 cardiac malformation, 1 metabolic disorder, 2 accidents and 1 infanticide. With this protocol, 7/45 deaths remained unexplained. This medical approach of the problem of sudden deaths in infants is beneficial to the counselling of the parents and to the management of subsequent children.
