We describe an acute onset of diabetes mellitus during third trimester of pregnancy revealed by ketoacidosis, complicated by fetal death, which could evoke fulminant type 1 diabetes, a novel subtype of type 1 diabetes first described in Japan and rarely described in Caucasian people. Diagnosis of diabetic ketoacidosis could be made on simple signs as abdominal pain, vomiting or ketone bodies on urinary multistix. Capillary glycaemic control is necessary to distinguish fast from ketoacidosis. The treatment of this severe imbalance must be initiated in emergency., (Copyright © 2010 Elsevier Masson SAS.

Objectives: Exclusive hepatocele is defined as a hernia containing in majority the liver with possibly some intestinal loops. This study was undertaken to evaluate neonatal morbidity and mortality in this series of exclusive hepatoceles., Materials and Methods: We reviewed 11 cases of exclusive hepatoceles with delivery at the hospital Jeanne-de-Flandre in the CHRU of Lille, in France., Results: The mean gestational age of diagnosis was 14.5+/-3.4 weeks of gestation. Karyotype determination was performed in 100% of cases: it was abnormal in one case of 11. One termination of pregnancy was performed because of trisomy 13. The mean gestational age at delivery was 38+/-1.8 weeks of gestation. Cesarean deliveries were performed in nine cases. Morbidity was important with: one case of fetal growth retardation on total hepatocele, three cases of severe respiratory distress, two cases of severe digestive complications. The mean length of stay was 42.8 days. The mean length of parenteral feeding was 14.4 days. Postnatal mortality concerned one child, which died because of a severe respiratory distress due to pulmonary hypoplasia., Conclusion: In this series, morbidity is thus important, making of exclusive hepatoceles a full entity among the omphaloceles. The multidisciplinary take care is more complex but conceivable.

Objectives: To study the efficiency of the official recommendations on the prevention of group B streptococcus and the impact of this strategy., Materials and Methods: A prospective study was realized in 2005. All infants who were live-born at the Jeanne-de-Flandre hospital (Lille, France) and their mothers were included in the study. Data concerned both pregnancy (vaginal screening, intrapartum antibiotic) and newborn (safe, colonization and early-onset neonatal bacterial disease)., Results: Our study included 4353 mother-newborn couples. Vaginal screening was performed on 92% of the women included in the study. Prevalence of vaginal group B streptococcus in screened women was 7%. Perpartum antibioprophylaxia of group B streptococcus was achieved in 12% of the women included in the study. Group B streptococcus was associated to 60% of probable and certain early-onset bacterial neonatal diseases, with an incidence of 9/1000 births. Exposition to antenatal antibiotherapy multiplied by two the risk of ampicillin resistant Gram-negative bacilli (RR=2 [1.1-3.8])., Conclusion: Recommendations were well followed, but in our health center group, B streptococcus was the main bacteria responsible for early-onset bacterial neonatal diseases. Because of the risk of germ selection, a more targeted antibioprophylaxia has to be preferred.

Introduction: Without promptly started antibiotic therapy, early neonatal bacterial infections incur a significant mortality. Superficial bacteriologic samples at birth have in France a real place for the diagnosis and the decision to treat a neonate., Objectives: In order to limit their indication and their choice, the aim of this article was to describe the proportion of neonates with samples and to determine the diagnostic value of the gastric aspirate, the ear swab and the placental sample., Methods: Neonates born in the CHRU of Lille in 2005 and staying in the maternity ward were prospectively included. Criteria for samples, type of samples and diagnosis taken were noted. Sensibility, specificity, positive and negative predictive values and likelihood ratios for a positive test and a negative test were calculated., Results and Conclusion: This study included 3918 neonates; 1.7% (65 children) were infected according to our criteria; 42.3% received bacteriologic samples. In accordance with the Anaes guidelines (2002), if mothers were Group B Streptococci positive and received intrapartum antibiotics (up to 2 injections) or did not have any screening test without any other indication of samples, the neonate did not have to receive bacteriologic samples. The gastric aspirate was the best exam thanks to the excellent negative predictive value of its direct examination: 99.4% (IC 95%: 98.8-99.7), its high likelihood ratio for a positive test: 10.04 (IC 95%: 8.29-12.15) and its low likelihood ratio for a negative test: 0.16 (IC 95%: 0.09-0.29); this sample could restrict the antibiotics' ratio given to the neonate. Placental sample could be taken only in certain indications.

Objectives: To assess the effect of the twin-to-twin delivery interval on the umbilical cord blood gas status and the neonatal outcome of the second twin following vaginal delivery., Patients and Methods: Retrospective study of twin deliveries at or beyond 34 weeks of gestation over a period of five years. The correlation between the twin-to-twin delivery interval, and the umbilical arterial blood gas parameters of the second twin, including pH, PO(2), PCO(2), HCO(3-) and base excess, was studied. A second analysis was performed after exclusion of non-vertex presentation, need for general anesthesia, growth restriction and weight difference between the twin>30%., Results: Two hundred and thirty-nine patients were studied. The mean twin-to-twin delivery interval was 11.3+/-6.4 minutes (between 6 and 14 minutes in 56.1% of cases). The second twin had more Apgar score<7 at 1 minute (P<0.02) and more arterial ombilical pH<7.20 (P<0.01) than the first twin. Over 15 minutes, the mean arterial pH was lower (P<0.01) and the number of arterial pH<7.20 increased (P<0.03). In contrast, the mean Apgar score and the rate of neonatal transfer did not differ significantly. There were significant negative correlations between arterial pH, base excess and bicarbonates and the twin-to-twin delivery interval (P<0.05). Similar results were found in the homogenised population. The reduction in the second twin arterial pH was expressed as pH=7.282-0.003 x time., Discussion and Conclusion: Umbilical cord arterial blood gas parameters deteriorate with increasing twin-to-twin delivery interval. Our results suggest that this interval should be less than 15 minutes, but obstetrician should adapt to every clinic situation.

Objectives: Analysis of our experience and propositions on the diagnosis and treatment of congenital bronchopulmonary malformations (BPM)., Population and Methods: Retrospective study of BPM diagnosed between 1997 and 2001. Analysis of clinical spectrum, diagnosis tools, treatment, and clinical outcome., Results: Thirty-two cases of BPM have been investigated (11 cystic adenomatoid malformations, 7 pulmonary sequestrations, 7 bronchogenic cysts, 4 congenital lobar emphysema, and 3 complex emphysematous malformations). Nineteen patients had a prenatal diagnosis. For 9 others, symptoms occurred before 4 years of age. Evaluation included a CT-scan in all patients (BPM involution in one). Surgical treatment was performed in 30 patients (lobectomy in 18), with a mean age of 7 months for asymptomatic patients. During the follow-up (mean: 3 years), respiratory symptoms were reported in 10 cases, 3 of them were related to the BPM., Discussion: Improvement in prenatal ultrasound diagnosis modified the management strategy. Considering the risk of pulmonary complications, surgical treatment is required during the first months of life. For congenital lobar emphysema, and some pulmonary sequestrations or small cystic adenomatoid malformations (<3 cm), conservative attitude may be preferred. BPM justify a multidisciplinary management.

Unlabelled: The aims of this work were to assess timing of complementary feeding in infants and to precise the underlying factors that may cause inappropriate complementary feeding., Patients and Methods: A cohort of 167 newborns, born in the same maternity ward during a 6 week-period, was prospectively analyzed. Only healthy neonates were included in the study. A phone questionnaire was filled at 4 and 6 months of age to evaluate modality of complementary feeding. Multivariate analysis (segmentation tree, analyse by multiple correspondence) was used to study factors associated with inappropriate diversification., Results: Out of the 167 neonates included in the study, 132 mothers could be contacted at 4 months and 116 at 6 months of age. Sixty-seven per cent of mothers started breast feeding at birth. Among these, 33% still breastfed -at least partially- at 4 months and 17% at 6 months. Fifty-two percent of mothers started complementary feeding before 4 months, and 24% of infants received gluten at 4 months of age. Multi-gravida mothers, mothers aged more than 35 years old and mothers who gave infant or follow-up formulae before 4 months, started complementary feeding significantly earlier (P<0.05). Infants who were formula fed received more frequently complementary feeding before the age of 4 months than breast fed infants (57% vs 33%, P<0.05)., Conclusion: Our study showed that half of infants were introduced solid food too early and allowed to identify a population at risk that could benefit from nutritional intervention programs.

We have compared the site-by-site N-glycosylation status of human lactoferrin (Lf) produced in maize, a monocotyledon, and in tobacco, used as a model dicotyledon. Maize and tobacco plants were stably transformed and recombinant Lf was purified from both seeds and leaves. N-glycopeptides were generated by trypsin digestion of recombinant Lf and purified by reverse-phase HPLC. The N-glycosylation pattern of each site was determined by mass spectrometry. Our results indicated that the N-glycosylation patterns of recombinant Lf produced in maize and tobacco share common structural features. In particular, both N-glycosylation sites of each recombinant Lf are mainly substituted by typical plant paucimannose-type N-glycans, with beta1,2-xylose and alpha1,3-linked fucose at the proximal N-acetylglucosamine. However, tobacco Lf shows a significant amount of processed N-glycans with one or two beta1,2GlcNAc linked to the trimannose core, which are weakly expressed in maize Lf. Finally, no Lewisa epitope was observed on tobacco Lf.

Unlabelled: This study was performed to describe the factors associated with a premature cessation of breastfeeding., Background and Methods: Three hundred and forty nine women with a plan for prolonged breastfeeding over two months were interviewed during their hospital stay to define sociological and medical variables. One month after discharge, mothers were contacted by a physician for making out evolution of the breastfeeding., Results: Eighty-eight (28%) women were no more breastfeeding their infant and were compared to the other 224 (64%) mothers. The main sociological factors influencing the cessation of breastfeeding were low education level (odds ratio 4.2 [95% CI 2.2-8.3]), and primiparity (odds ratio 2.1 [95% CI 1.1-3.9]). Pacifier use was associated with a lower duration of breastfeeding (odds ratio 2.5 [95% CI 1.4-4.5]). Medical predictive factors were infant weight loss (odds ratio 4.3 [95% CI 1.7-10.6]), respect of intervals between feeding times (odds ratio 2.1 [95% CI 1.1-4.4]), delay before the first feeding (odds ratio 1.9 [95% CI 1.0-3.6]). On the other hand formula supplementation was not related with cessation of breastfeeding., Discussion and Conclusion: As the success of breastfeeding depends on maternal motivation, it seems essential to take into account mothers' plan to study breastfeeding duration. The knowledge of predictive factors of the cessation of breastfeeding should allow to identify mothers who need particularly the attention of healthcare professionals.

In order to determine the N-glycosylation potential of maize, a monocotyledon expression system for the production of recombinant glycoproteins, human lactoferrin was used as a model. The human lactoferrin coding sequence was inserted into the pUC18 plasmid under control of the wheat glutenin promoter. Maize was stably transformed and recombinant lactoferrin was purified from the fourth generation seeds. Glycosylation was analysed by gas chromatography, lectin detection, glycosidase digestions and mass spectrometry. The results indicated that both N-glycosylation sites of recombinant lactoferrin are mainly substituted by typical plant paucimannose-type glycans, with beta1,2-xylose and alpha1,3-linked fucose at the proximal N-acetylglucosamine, and that complex-type glycans with Lewis(a) determinants are not present in maize recombinant lactoferrin.

From October 1993 to February 1998, 33 cases of fetal cardiac arrhythmia were investigated by doppler-echocardiography at the Lille infantile and congenital cardiology department. Extrasystolic arrhythmias were the most frequently encountered disorder (25 fetuses, i.e., 76% of cases: 24 instances of extrasystolic auricular arrhythmia and one case of extrasystolic ventricular arrhythmia). They were invariably benign, and apart from one case only required standard monitoring. Tachycardia was observed in 15% of cases (three cases of supraventricular tachycardia [SVT] and two cases of auricular flutter [AF]). In no instance was a cardiopathic syndrome noted. A number of efficient treatments have been described, but the prognosis is often poor in the presence of hydrops fetalis. Direct fetal treatments (cordocentesis) are currently under evaluation, and at present can only be used as a last resort. In our series, one fetus died 15 minutes after transplacental Flecaine (flecainide) administration. Two of the three SVT and the two AF cases were successfully treated. Bradycardia, which was unassociated with extrasystolic arrhythmia, was found in 9% of cases. It is concluded that Flecaine is probably the treatment of choice for supraventricular and ventricular fetal tachycardia, as it has no teratogenic effect and crosses the placenta at a fetal concentration that is 80% of the maternal level. However, the administration of this drug is not without risk. It is known to possess certain negative side effects, and its pharmacological profile and maternal and fetal health risks have not yet been fully investigated. At present, no entirely safe and efficient treatment for fetal cardiac arrhythmia has been found.

Background: The aim of this study was to determine the influence of medical and non-medical factors on perinatal health in an underpriviledged area, the ex-coal mines of Lens (Pas-de-Calais)., Population and Methods: This prospective study concerned 1,000 women who delivered in the maternity hospital of Lens between January 5, 1993 and May 13, 1993. The relationships between preterm delivery, low birth weight and maternal socioeconomic and cultural characteristics were analyzed., Results: The women included presented adverse pregnancy outcomes. Preterm delivery, low birth weight and neonatal transfer rates were respectively 6.9%, 7.3% and 12.7% higher than the average regional rates. In contrast with these results, antenatal care could be considered correct or even better. The poor socioeconomic status of the population appeared to be a very significant perinatal risk factor., Conclusion: At present, in an unfavourable regional conjuncture, socioeconomic and cultural factors have adverse effects on perinatal morbidity and mortality independent of medical factors like prenatal care. The prevention of poor perinatal outcome should be based on these data. Not the access to the health care system but the manner of dispensing health care should require great consideration.

A prospective study was conducted in 3056 live-born infants delivered at the Jeanneade-Flandre maternity hospital of the Lille Teaching Hospital between January and August 1997. Clinical, laboratory test, and microbiological test findings were compared. A cohort of 1003 infants who remained in the maternity ward but were considered at increased risk of maternofetal infection (MFI) based on history and/or obstetrical criteria and/or neonatal criteria underwent routine collection of specimens including gastric fluid, auricular and anal swabs, amniotic fluid, and placental fragments. Microscopic examination of gastric fluid smears, the first result available to the clinician, was found to have 27.5% sensitivity (983 samples). Positive predictive value (PPV) was only 17.8% because of a high rate of colonization (16.8%), defined as absence of clinical symptoms and three peripheral specimens positive for the same organism. However, negative predictive value (NPV) was as high as 99.8% as a result of high sensitivity (97.8%) in the infected neonates. The gastric fluid smear was positive in 30% and 35% of neonates born to mothers with hyperpyrexia during early and late labor, respectively, and in 42% of neonates born to mothers with a history of group B streptococcus carriage during the pregnancy. Forty-two per cent of neonates with a history of fetal tachycardia had a positive gastric fluid smear. Diagnostic criteria for infection were three peripheral specimens positive for the same organism, C-reactive protein elevation, and/or one or more clinical signs suggestive of infection, and/or a positive central specimen (blood, CSF). The infection rate in infants who remained in the maternity ward was 1.6%. The most common causative organisms were group B streptococci. These findings illustrate the useful contribution of gastric fluid smears to the early diagnosis of MFI and confirm the predominant role of group B streptococci.

Objective: To present the different etiologies of fetal cerebral ventriculomegaly (VA) and try to evaluate prognosis., Materials and Methods: A retrospective analysis was made in 141 cases of fetal cerebral ventriculomegaly diagnosed in our obstetrics department between January 1988 and December 1996., Results: Mean gestational age at diagnosis was 24.8 weeks. Myelomeningoceles were the most frequent etiology (50 cases, 36%), usually diagnosed late in pregnancy (25 weeks gestation). Termination of pregnancy was the most frequent outcome. Agenesis of the corpus callosum (ACC) was observed in 16 cases (11%), 8 of them being diagnosed before birth. This etiology has been an important diagnostic problem until recent years. The advent of improved imaging techniques has facilitated diagnostic procedures. Thus in 1996, the 4 ACC were all diagnosed by prenatal ultrasound. The 8 live infants presented developmental retardation. Termination of pregnancy has been performed more and more frequently in accordance with parent wishes. In 6 cases (4%), the etiology was congenital infection. When a chromosome anomaly was found (7%), ventriculomegaly was always associated with other ultrasonographic anomalies. Ventriculomegaly was associated with other malformations in 23% of the cases but only 17% were discovered prenatally; all the live infants but one had severe neurological impairment. Ventriculomegaly was considered to be the unique anomaly in 37% of the prenatal cases and was truly unique in 24%, an etiology being found in 6%. No explanation was found in 18%. The outcome of live infants is known in 139 cases (2 children lost to follow-up) after a 6 month to 6 year follow-up. Overall prognosis was severe as among the 42 infants (30%), 14 (10%) are well including 12 who had ventriculomegaly alone., Conclusion: Prenatal diagnosis of ventriculomegaly implies a severe prognosis. Only children presenting limited ventriculomegaly alone have normal neurological development. In case of ventriculomegaly, clinicians must search carefully for other anomalies, always associated with poor prognosis.

Objective: The clinicopathologic features of a rare familial form of congenital blister are analyzed to assess what factors could lead to the cutaneous split., Methods: Three consanguinous newborn babies had a congenital ichthyosis with eosinophilia and elevated total immunoglobulin E. The type and level of the split were studied on skin biopsies performed on the first day of life., Results: The level of the split was located within the corneocytes. Isolated eosinophilic granules were found at this site. Desmosomes and the dermoepidermal junction were intact. Blisters and eosinophilia resolved in 3 weeks, and there was no recurrence during 4 and 6 years of follow-up in two of the patients., Conclusion: Peeling skin syndrome is a rare blistering disorder of the newborn that should be recognized because it has a good prognosis. Eosinophils may play an important role in the cutaneous split of this congenital ichthyosis.

We have previously described a passive inflation method during constant inspiratory flow for measuring total respiratory elastance and resistance during mechanical ventilation in newborns. The simple method for measuring respiratory mechanics had been assessed during decelerating inspiratory flow obtained with pressure controlled ventilation (PCV). We report an application of this method to preterm and full-term mechanically ventilated newborn infants and a comparison with the occlusion method. Twenty-one newborn infants (birth weight 1,060 to 3,650 g; gestational age 26 to 41 weeks), between 1 to 55 days of postnatal age, were enrolled in the study. They were ventilated with a "Servo ventilator 900C," first set in the pressure-controlled mode and then in the volume-controlled mode without changing the tidal volume (VT), inspiratory time or ventilator rate. Flow was measured through a pneumotachograph inserted between the endotracheal tube (ETT) and the breathing circuit; VT was obtained by integration of flow and airway pressure measured directly at the airway opening. Flow, volume, and pressure were plotted on analog X/Y tables to obtain pressure-volume (P/V) and flow-volume (V/V) loops, as well as pressure-time curves. Occlusion was performed by using the end-inspiratory and the end-expiratory pause buttons of the ventilator. The passive inflation method during PCV was based on the analysis of P/V and V/V loops and provided compliance (Crs(PC)infl.), resistance Rrs(PC)infl.) of the respiratory system, and intrinsic positive end-expiratory pressure (PEEP(PC)i,infl.). These values were compared with (1) compliance (Crs(PC)occl.) and intrinsic positive end-expiratory pressure (PEEP(PC)i,occl.) measured by the occlusion method during PCV; (2) static (Crs(VC),occl.) and dynamic (Crs(VC),dyn.) compliance, airway (R(aw)(VC),), tissue (Rrs(VC),visc.) and total resistance (Rrs(VC),occl.), and intrinsic positive end-expiratory pressure (PEEP(VC)i,occl.) measured by the occlusion method during volume-controlled ventilation. Crs(PC),infl. correlated well with Crs(PC),occl., Crs(VC),occl., and Crs(VC),dyn.. Furthermore, Crs(PC),infl. and Crs(VC),dyn. did not differ significantly. Rrs(PC),infl. correlated well and did not differ significantly from total inspiratory resistance, i.e., the sum of R(aw)(VC) and Rrs(VC),vis. PEEPPC,i,infl. correlated well and did not differ significantly from PEEP(PC)i.occl. and from PEEP(VC),i,occl. The passive inflation method can be used during PCV with a decelerating flow waveform. It provides dynamic compliance, inspiratory resistance of the respiratory system, and intrinsic PEEP from the analysis of V/V and P/V loops recorded at the airway opening. This technique is simple to use and well tolerated by preterm and full-term ventilated newborn infants. It can be a good alternative to occlusion methods.

Care given to 1,425 consecutive new-born infants in a University Maternity Ward was screened for high-risk pregnancies. The characteristics of the new-borns retained for study resulted from this choice. Life-threatening distress, defined as the need for respiratory assistance beyond the third minute of life, was observed in 6% of cases. Distress had been predicted 30 minutes before birth in only 42% of cases. In 56.5%, the signs of distress occurred outside "normal" working hours and immediate care was given by the mid-wife in 36% of cases. Despite progress in fetal medicine, these findings would suggest that life-threatening distress at birth is often unpredicted and occurs at a non-negligible rate. This would emphasize the need of training the entire obstetrical team, especially the mid-wives in care the for new-borns.

The pharmacokinetics of piperacillin after a single 75-mg/kg intravenous injection as analyzed in 28 neonates with gestational ages of 29 to 40 weeks (A = 29 to 31 weeks, B = 33 to 35 weeks, C = 38 to 42 weeks) and birth weights of 860 to 3900 g during 35 courses. Serum concentrations of piperacillin were determined by high pressure liquid chromatography. A one compartment open model characterized the disposition of piperacillin. Twenty courses were given between Day 3 and Day 5 of life. The elimination half-life and total body clearance were related to gestational age. Differences were significant between Groups A and B and Group C for half-life (4.3 +/- 1.9 and 3.35 +/- 0.75 vs. 2.47 +/- 0.72 hours) and for clearance (1.68 +/- 0.6 and 1.8 +/- 0.4 vs. 2.46 +/- 0.36 ml/min/kg). Volumes of distribution were similar in the 3 groups, from 516 +/- 108 to 633 +/- 226 ml/kg. Fourteen courses were given from Day 9 to Day 11 of life. The same differences were observed between Groups A and B and Group C. Elimination half-life was significantly reduced with simultaneous increase of the total body clearance. In clinical practice, 75-mg/kg intravenous injections every 12 hours during the first week of life and every 8 hours in the second week provide appropriate concentrations in infants of less than 36 weeks gestational age. In full term newborns the 75-mg dosage is appropriate but the number of injections must be increased to 3/24 h for the first week and 4 times daily thereafter.

A passive inflation method was described for measuring total respiratory elastance and resistance during mechanical ventilation in adult patients (Rossi et al., J Appl Physiol 58:1849, 1985). We applied this method to preterm and full-term mechanically ventilated newborn infants and we compared the results with those obtained by the occlusion method. We performed 37 tests in 16 newborn infants (B.W. 880-4,500 g; G.A. 28-42 weeks), between 1 and 45 days of postnatal age, ventilated with a Servo Ventilator 900C, set in controlled-volume mode. Flow was measured through a pneumotachograph inserted between the endotracheal tube (ETT) and the breathing circuit, tidal volume by integration of flow and airway pressure directly at the airway opening. Flow, volume, and pressure were recorded on an X/Y plotter to obtain pressure-volume (P/V), flow-volume (V/V) loops, and pressure-time curves. Occlusion was performed by using the end-inspiratory and the end-expiratory pause buttons of the ventilator. Analysis of P/V and V/V loops provided respiratory system compliance (Crs, infl.), resistance (Rrs, infl.), and "intrinsic positive end-expiratory pressure" (PEEPi, infl.). These values were compared with Crs, occl., Rrs, occl., and PEEPi, occl. measured by the occlusion method. The measurements were well correlated (Crs, infl./Crs, occl.: r = 0.90; Rrs, infl./Rrs, occl.: r = 0.91; PEEPi, infl./PEEPi, occl.: r = 0.91). Rrs, infl./Rrs, occl. and PEEPi, infl./PEEPi, occl. did not differ significantly. However, Crs, occl. was 15% higher than Crs, infl. (P less than 0.01). The passive inflation method is simple to use and well tolerated in preterm and full-term ventilated newborn infants, it provides accurate results, and can be a good alternative to occlusion methods. It requires, however, a constant inflation flow and adaptation to the ventilator.

In the French region Nord-Pas-de-Calais a Public Health action was undertaken in order to set up a training program for neonatal resuscitation for the maternity-hospitals personnel. The incidence and severity of meconium aspiration among the population of children admitted to the neonatal intensive care unit of Lille University Hospital during two 15 month-periods of time, before and after the training, were compared. The number of neonates who presented with meconium aspiration decreased from 54 during the first period to 9 during the second, i.e. from 7.2 to 1.3% with respect to the total number of hospitalized patients (p less than 0.001). On the contrary, the number of deaths did not decrease significantly. This regression of the meconium aspiration gives evidence for an improved quality of care at birth. Even if training is not the only factor, this evolution gives argument in favour of the efficacy of such actions.

In order to better define the outcome of patients with neonatal congenital diaphragmatic hernia (CDH), 17 patients between 3 and 19 years of age, among 34 survivors from 100 CDH have been re-examined clinically. All had a lung radiography, lung function studies, and radionuclide (Technetium 99m, Xenon 133) lung scans. Three patients suffered from asthma, 2 had recurrent bronchitis, 4 poor tolerance to effort, 3 gastrooesophageal regurgitation leading to endobrachyoesophagus and oesophagitis in one, 3 had scoliosis. Lung scans demonstrated hypoperfusion of the herniated side (less than 40%) in 6 patients. Chest films showed hypovascularisation on the herniated side. Lung function studies, performed in 4 of these 6 patients, showed a restrictive syndrome in 1 patient. Our results confirm those in the literature: perfusion is more altered than ventilation. Chest films at one year of age, completed if necessary by radionuclide lung scans, allow identification of children who have important pulmonary hypoplasia. These children need a regular follow-up: respiratory, digestive and orthopedic complications must be treated in order to preserve the respiratory function in adulthood.

In a case of neonatal hypertension, radiographic findings showed multiple thromboembolism from the ductus arteriosis diverticulum. Hypertension was well controlled by captopril during the neonatal period. The long-term follow-up of 8 years with normal cardiovascular and renal function indicates a good prognosis for acquired renovascular neonatal hypertension.

Among 315 infants treated for respiratory distress syndrome (RDS) over a 2 year period, 32 prematures were studied retrospectively with the diagnosis of pulmonary interstitial emphysema (PIE). Eighteen died. In this group, birth weight below 1600 g, need for oxygen above 0.6 on the 1st day and appearance of bilateral pulmonary interstitial emphysema within the first 48 h of life were significant risk factors, with a mortality rate of 94%. In order to recognize one or more early criteria predictive of fatal PIE, we compared ventilation parameters on day 1 between neonates with fatal PIE and those with the same birth weight and initial severity of RDS but without PIE treated during the same period. High positive inspiratory pressure on day 1 was found to be the most significant parameter associated with further appearance of fatal pulmonary interstitial emphysema. A cut-off level of 26 cm H2O was found to be discriminant. These criteria may be useful in selecting those neonates who might best benefit from a new therapy such as high frequency ventilation, before irreversible lesions appear.

127 infants were born alive before the 32nd week of gestation in the H. Salengro obstetrical unit from the University Hospital of Lille from January 1980 to December 1985. During this period the annual number of deliveries was constant, 2700. Two periods were considered, 1980-1982 and 1983-1985. The number of such premature infants increased slightly: from 56 to 71. The most striking feature was the dramatic increase in infants born after induction of delivery for fetal reasons. Another finding is the statistically significant lowering of gestational age and birthweight of the spontaneously born infants. These trends counterweight the efficacy of the policy of prevention. When considering the morbidity and the mortality, hyaline membrane disease still plays a preeminent role in this population.

Twenty cases of cystic adenomatoid malformation of the lung were observed: 2 had died in utero; the diagnosis was made at birth in 13 infants of which 3 were premature. A Bochdalek's hernia had been diagnosed before birth in 2 cases by echo-tomography. The correct antenatal diagnosis had been made in 2 cases. Two infants had no symptoms, 3 were dyspneic, 8 were in respiratory distress and had to be intubated and ventilated. Two had a prune belly syndrome. Eight infants had a thoracotomy during their first week of life. Pulmonary resections concerning those 13 patients comprised 10 lower lobectomies, 1 of which was associated with a lingulectomy, and 2 upper lobectomies, 1 of which was associated with a middle lobe resection. Five patients were diagnosed and operated upon between 10 months and 8 years of age; 4 had recurrent bronchitis and 1 was diagnosed during the treatment of a gastroenteritis. They had 3 lower and 2 upper lobectomies. Recovery was uneventful in all patients except for 1 who was reoperated upon for intestinal obstruction. Antenatal diagnosis of cystic adenomatoid malformation should become standard. The malformation may be mistaken for a pulmonary sequestration or bronchogenic cyst. Differential diagnosis of a congenital hernia is important.

The possible role of pleural drainage in the occurrence of diaphragmatic palsy in newborns in considered.

The authors review five cases of actinomycosis with thoracic involvement, and emphasize the importance of parietal manifestations and their radiological appearance in the diagnosis of such cases. They refer particulary to the bone locations of the disease and mention rare oesophageal lesions and the development of systemico-pulmonary shunts.

We report 3 cases of acrocephalosyndactyly V (Pfeiffer syndrome) in the same family. This syndrome is characterized by coronal craniosynostosis with facial dysmorphism and specific malformations of the extremities (wide stubly adducted thumbs). The pattern of inheritance in autosomal dominant. The place of this syndrome is discussed in the group of disorders associated with acrocephalopolysyndactyly.

A non-selective series of 48 neo-nates was treated during a period of 8 years (1978-1985), with follow-up more than four months for recent observations. Surgical treatment comported Gross-technique in 32 cases; immediate total-closure in 7 cases and progressive reintegration (Schuster) in 10 cases. Long-term parenteral nutrition was performed in 38 neo-nates. The etiology of different deaths (toxic++-infection, mechanical obstruction) is discussed. The percentage of survivors was progressively raised: 70% since 3 years, and better in the last 11 cases, all with good result.

The finding of an abdominal mass in an 18-month old infant ultimately led to the diagnosis of mycotic aneurysm of a common iliac artery. The lesion was resected and the vessel was ligated. The short and long-term outcome was favourable. The child had been operated upon for cervical teratoma and had undergone catheterization of the umbilical artery complicated with Staphylococcus aureus infection. The presence of a mycotic aneurysm must be suspected in infants with a history of umbilical artery catheterization or neonatal staphylococcal infection, or presenting with a posterior mediastinal or abdominal mass, or arterial hypertension. The vessel most commonly involved is the aorta. Surgical resection, when performed, results in cure. The present case is remarkable on three points: the lesion involved an iliac artery, the diagnosis was delayed and calcifications were present around the aneurysm.

Follow-up studies of low birth weight infants concern usually infants selected on the basis of either the birthweight--inferior or equal to 1500 g--or the gestational age: the upper limit is 31 or 32 weeks. To determine the most pertinent criterium, mortality and neurodevelopmental outcome at two years were compared in 3 groups, selected on the above criteria from a cohort of 369 infants with a birthweight below 2,000 grams admitted in 1983 in the neonatal unit of the University hospital of Lille. Under 1501 grams the rate of small for gestational age infants is high: it could be a part of the explanation for the high rate of minor sequelae. When cohorts are selected on the basis of gestational age, it appears that mortality is low at 32 weeks but the rate of major and moderate sequelae is still high: that fact must be considered when premature induced delivery comes in discussion. Because these criteria select different high risk populations, mortality and neurodevelopmental follow-up studies should include all infants with gestational age inferior or equal to 32 weeks and/or birthweight inferior or equal to 1,500 grams.

The ultrasonographic study through the fontanelle of 192 children below 33 weeks of age and surviving after the neonatal period led to the diagnosis of leukomalacia by identifying anechogenic cavities in the periventricular area in 7 cases. Clinical pictures were not characteristic. Important electro-encephalographic changes were constantly found, even before the occurrence of sonographic signs. Although non specific they are still suggestive when associated hemorrhage is not present. With these criteria, diagnosis seems to be correlated with severe neurologic prognosis. Its interest and chronology warrant the extension of the ultrasonographic supervision of severely immature infants up to the end of the second month.

A case of Stickler's syndrome is reported. This syndrome associates eye defects, craniofacial and musculo-skeletal abnormalities, sensori-neural hearing loss and mitral-valve prolapse. It is an autosomal dominant disorder probably resulting from a connective tissue dysplasia. There is a major risk for the occurrence of serious ocular problems (blindness), and ophthalmologic follow-up has to be performed on affected persons and relatives in order to improve the long term prognosis.

A retrospective study of 182 children with birth weights less than or equal to 2,000 gms was undertaken. Its analysis showed that heterogeneity in discharge weights (1,580 to 3,400 gms) corresponded to an homogeneous average gestational age, around 39 weeks. Low discharge weights were neither correlated with the pathology of the first days, nor with the socio-economic status of the family. The majority were children born with intra-uterine growth retardation, who mature more rapidly and who might be given to their families earlier, with lower weights. There was no correlation between discharge weight and a second hospitalization during the first year. A policy of "early" discharge did not seem to have disadvantages, while its advantages are unquestionable.
