Abstract
BACKGROUND The role of nasal continuous positive airways pressure (nCPAP) in the management of respiratory distress syndrome in preterm infants is not completely defined. OBJECTIVE To evaluate the benefits and risks of prophylactic nCPAP in infants of 28-31 weeks gestation. DESIGN Multicentre randomised controlled clinical trial. SETTING Seventeen Italian neonatal intensive care units. PATIENTS A total of 230 newborns of 28-31 weeks gestation, not intubated in the delivery room and without major malformations, were randomly assigned to prophylactic or rescue nCPAP. INTERVENTIONS Prophylactic nCPAP was started within 30 minutes of birth, irrespective of oxygen requirement and clinical status. Rescue nCPAP was started when Fio2 requirement was > 0.4, for more than 30 minutes, to maintain transcutaneous oxygen saturation between 93% and 96%. Exogenous surfactant was given when Fio2 requirement was > 0.4 in nCPAP in the presence of radiological signs of respiratory distress syndrome. MAIN OUTCOME MEASURES Primary end point: need for exogenous surfactant. Secondary end points: need for mechanical ventilation and incidence of air leaks. RESULTS Surfactant was needed by 22.6% in the prophylaxis group and 21.7% in the rescue group. Mechanical ventilation was required by 12.2% in both the prophylaxis and rescue group. The incidence of air leaks was 2.6% in both groups. More than 80% of both groups had received prenatal steroids. CONCLUSIONS In newborns of 28-31 weeks gestation, there is no greater benefit in giving prophylactic nCPAP than in starting nCPAP when the oxygen requirement increases to a Fio2 > 0.4.

Abstract
At birth, the total body iron content is approximately 75 mg/kg, twice that of an adult man in relation to weight. During the first 6 mo of life, total iron body content increases slightly and exclusive breastfeeding is sufficient to maintain an optimal iron balance. Thereafter, iron body content substantially increases and the infant becomes critically dependent on dietary iron, provided by complementary foods. Numerous factors may contribute to nutritional iron deficiency in infancy, the most important being low body iron content at birth, blood loss, high postnatal growth rate, and a low amount and/or bioavailability of dietary iron. We have documented that the prevalence of iron deficiency declined in Italy as iron nutrition improved and that early feeding on fresh cow's milk is the single most important determinant of iron deficiency in infancy. Healthy full-term infants should maintain optimal iron balance by consuming a good diet, which can be summarized as follows: breastfeeding should be continued exclusively for at least 5 mo and then together with complementary foods containing highly bioavailable iron; infants who are not breastfed or are partially breastfed should receive an iron-fortified formula, containing between 4.0 and 8.0 mg/L iron, from birth to 12 mo of age; fresh cow's milk should be avoided before 12 mo of age.

Abstract
This study was designed to collect data on the prevalence of respiratory syncytial virus (RSV) infection in Italy in infants hospitalized for lower respiratory tract infections, and to evaluate which of the recognized risk factors might be associated with disease severity. Thirty-two centers throughout Italy participated in the study. Over a 6-month period (November 1,1999 to April 30, 2000), we evaluated all children < 2 years of age hospitalized for lower respiratory tract infections. All subjects were tested for RSV within 24 hr of hospitalization by using an immuno-enzymatic diagnostic test (Abbott Testpack, RSV). Logistic regression was used to identify the factors that might be associated with more severe disease or could increase the likelihood of RSV positivity in hospitalized infants. Out of a total of 1,232 children enrolled, 40.6% were found to be RSV-positive (RSV+). The peak of the RSV epidemic occurred in February, while the lowest prevalence of RSV positivity was seen in November (P < 0.05). A high proportion of study subjects had low birth weight and low gestational age. The clinical diagnosis at hospitalization was bronchiolitis in 66.7%, pneumonia in 15.3%, and wheezy bronchitis in 18.1%. In the bronchiolitis group, a higher prevalence of RSV+ was found in patients with gestational age <or= 33 weeks or 34-35 weeks, as compared to those with a gestational age >or= 36 weeks (P < 0.04). No differences were found in the proportion of RSV+ patients in the three gestational age subgroups with pneumonia and wheezy bronchitis (P > 0.05, each comparison). Independent of the clinical diagnosis at admission, RSV infection was associated with more severe respiratory impairment. Environmental smoke exposure was higher in subjects with bronchiolitis than in those with wheezy bronchitis (P < 0.04), and RSV+ was positively related with the birth order (P < 0.05). The presence of older siblings and birth order plays an important role in RSV infection. The collected data show that, in Italy, RSV is an important cause of lower respiratory tract infection in infants. Gestational age, birth order, birth weight, and exposure to tobacco smoke affected the prevalence and severity of RSV-related lower respiratory tract disease.

Abstract
Thrombotic disease is rare in neonates. The main risk factors at this age are perinatal asphyxia, maternal diabetes, sepsis, polycythemia, dehydration, a low cardiac output, and in primis the catheterization of central lines. Another important risk factor is inherited thrombophilia. Arterial thrombosis is even more rare than venous thrombosis and less related to most of the risk factors listed above; it occurs more frequently in the iliac, femoral, and cerebral arteries but very rarely in the aorta. Most of the described cases of aortic thrombosis are associated with the catheterization of an umbilical artery and involve the descending tract and the renal arteries; very few relate to the ascending tract and the aortic arch. The possible role of virus-induced primary vascular endothelium damage in the etiopathogenesis of neonatal arterial thrombosis has been previously hypothesized. Herpesviruses, particularly human cytomegalovirus (HCMV), can infect endothelial cells and directly damage intact vascular endothelium, altering its thromboresistant surface as a result of procoagulant activity mediated by specific viral surface phospholipids, necessary for the coagulation enzyme complex assembly that leads to thrombin generation. We describe a case of congenital aortic arch thrombosis. The clinical, laboratory, and virologic pictures; the anatomopathologic findings (fully compatible with viral infection); the detection of HCMV in various tissues (including the aorta); and the absence of other causes of aortic thrombosis make it possible to attribute the case to a severe congenital HCMV infection with multiple organ involvement, after the primary infection of the mother. The hemostatic system disorders and hemodynamic disturbances related to viral cardiac damage explain the clinical features of the case and indicate that congenital HCMV infection should be included among the causes of neonatal aortic thrombosis.

Abstract
Sepsis is still one of the most important causes of mortality and morbidity in the neonatal period. Infection is responsible for approximately 2 million neonatal deaths per year in developing countries. In Italy, as in other industrialized countries, the mortality rate has declined to 5.1 per 1000 livebirths. Progress in obstetrics and neonatal intensive care competence have improved survival particularly of preterm and low birth weight neonates. These neonates, for the immunological state and the invasive therapies they are subjected to, are extremely at risk for sepsis. Knowledge of neonatal risk factors, together with cytokines evaluation as early markers of sepsis and laboratory tests such as polymerase chain reaction, have allowed us to accelerate the diagnosis of sepsis with prognostic improvements. The frequent involvement of group B streptococci and coagulase-negative staphylococci requires empiric antibiotic therapy, effective for these pathogens, in all infants with suspected infection, waiting for blood cultures and antibiotic susceptibility results. Breast milk, carrier of immunologically active agents, is still the best prophylaxis for neonatal sepsis.

Abstract
BACKGROUND The aim of this study was to evaluate health state of newborns of immigrated parents from developing countries. METHODS Hospital records of 69,605 infants born during 1996/1997 in Italy were reviewed comparing, in a case-control study, each infant of immigrated parents to two infants born immediately before and after to Italian parents. RESULTS Of the 69,605 newborns 3906 (5.6%) were born to immigrated parents. This prevalence prolongs the increasing trend observed during the last 10 years of infants born to immigrated parents and reduces the fall of the birth rate linked to the few infants born to Italian parents. It was influenced by geographical factors, being higher in Northern-Central Italy (7%) than in Southern and Insular Italy (2.8%), as consequence of more elevated incomes in these Italian regions. The origin countries of immigrated parents were mainly Northern Africa (31.7%), Eastern Europe (18%) and Sub Saharan Africa (11.6%). Infants of immigrated parents showed higher incidences of prematurity, low birth weight, asphyxia and neonatal mortality rate than newborns with Italian parents. These higher incidences appeared related to some risk factors such as higher parity, short gestational age, some maternal infections, maternal drug dependence, maternal age less than 18 years, low familiar income, inadequate obstetric cares, difficulty to accessing the public health services. CONCLUSIONS The health problems of infants with immigrated parents are mainly related to social disadvantage and can be overcome improving the social state, the lifestyles and the obstetric cares of the immigrated women, so as monitoring their risk pregnancies.

Abstract
We have examined the relationship between the common dopamine D4 receptor (DRD4) exon III repeat polymorphism and infants' behavior measured with the Italian version of the Early and Revised Infancy Temperament Questionnaires (EITQ/RITQ) in 122 Italian neonates at 1 and 5 months of life, when the genetic contribution to the behavior can be more clearly assessed. Two-way (genotype x age) analysis of variance revealed a significant correlation with the temperamental subscale of adaptability [F(1, 120) = 5.26, P < 0.02]. At 1 month of life (early assessment), infants with long (L) DRD4 alleles presented significantly low scores (L 2.61 +/- 0.073; S 2.84 + 0.79; Newman-Keuls P = 0.03) in comparison with the high scores of infants with short (S) alleles (L 2.4 +/- 0.059; S 2.25 +/- 0.57). These differences were not detected at 5 months of life (late assessment), denoting a strong environmental effect at this age on the genetic background. These results confirm and extend the genetic influence of the DRD4 gene in human temperament at birth.

Abstract
A cohort of 1567 infants was studied at birth and at 3 mo of age to elucidate factors possibly affecting feeding policies in the maternity ward and the relationship with subsequent feeding patterns. During their stay in the maternity wards 89.6% of infants were breastfed, with 28.1% receiving formula in addition to mother's milk. Independent predictors of receiving a formula supplement in the maternity wards as a result of multivariate analyses were the separation of the newborn from the mother, a birthweight lower than 3000 g and a gestational age lower than 38 wk. At 3 mo of age, 66.1% infants were still at least partially breastfed and 48.9% were exclusively breastfed. An increased risk of not being breastfed at 3 mo of age was related to supplementary feeding at birth and birthweight. A weak relationship was found between the prevalence of breastfeeding at 3 mo of age and the magnitude of routine formula supplement use in the maternity ward. Given the present trends for early discharge from maternity wards and the National Health System facility for free paediatric assistance after discharge, in Italy paediatricians should be the main actors to support the continuation of breastfeeding.

Abstract
Infant formulas containing partially hydrolyzed cow milk-proteins are used for the prevention of allergy when maternal milk is not available, and, in preterm infants, also for improving gastric emptying. The nutritional adequacy of such formulas has not yet been completely defined. As the type of feeding may influence the antibody response to immunization, the aim of the present study was to evaluate the antibody response to oral polio virus immunization in term infants and to acellular pertussis and hepatitis B immunization in preterm infants, exclusively fed a partially hydrolyzed cow-milk formula during the first 5 months of life, in comparison with exclusively breast-fed infants. Active immune response occurred in all the infants after the second dose of immunization and no significant difference in the antibody titres was found according to the type of milk. On the basis of these results, it seems that protein nutrition based exclusively on a partially hydrolyzed formula does not impair the response to immunization in both preterm and term infants.

Abstract
The present study reports immunohematological data (anti-erythrocyte titer, anti-erythrocyte functional activity, percentage of sensitized erythrocytes) in 11 patients with erythroblastosis fetalis transfused in utero (IUTd). At birth it was possible to define two groups of newborns: one with low (group 1) and one with high (group 2) percentage of circulating sensitized erythrocytes, respectively. The presence of a low rate of sensitized red cells at birth in IUTd infants did not reduce the number of exchange transfusions required postnatally. On the contrary, babies of this group were affected by a more severe disease as shown by higher anti-erythrocyte maternal titer, higher anti-erythrocyte functional activity and a higher degree of fetal hemolysis. The persistence of hemolysis after birth, in spite of the absence of sensitized circulating erythrocytes, may be due to intramedullary hemolysis.

Abstract
Several combined vaccines have recently been developed, in order to improve the implementation of immunization programmes and increase the coverage for each vaccine. As the response of preterm infants may vary depending on the vaccination schedule and the vaccine product, it should be evaluated specifically as new vaccines become available. In this study we have examined the antibody response to a combined diphtheria, tetanus, acellular pertussis, and hepatitis B vaccine (DTPa-HBV), given as a primary vaccination course at 3, 5 and 11 months of postnatal age, in 34 preterm infants (mean gestational age (GA) = 32.0 weeks) in comparison with 28 term infants. At the end of the primary course, preterm infants had antibody concentrations for pertussis 69 kDa antigen and diphtheria toxoid that were significantly lower than those of term infants; preterm infants with GA < or = 31 weeks had antibody concentrations for pertussis 69 kDa antigen and HBsAg that were significantly lower than those of preterm infants with higher GA; anti-HBs antibody levels correlated with GA. However, the combined DTPa-HBV vaccine elicited seroconversion to all its components in all but two infants, one term and one preterm, after the second dose and a total seroconversion after the third dose. We conclude that preterm infants may be immunized with a combined DTPa-HBV vaccine, starting at the same chronological age, as term infants.

Abstract
We evaluated the circulating levels of GH, insulin-like growth factor I (IGF-I), GH-binding protein (GHBP), and IGF-binding protein-3 (IGFBP-3) before L-T4 therapy in 19 infants with congenital hypothyroidism (CH), aged 12-29 days, diagnosed by neonatal screening and in a group of age- and sex-matched control infants. The same parameters were reevaluated after several months of treatment. Serum GHBP was measured by the high performance liquid chromatography-gel filtration method; serum GH, IGF-I, and IGFBP-3 levels were determined by commercial kits. The hypothyroid patients, before beginning therapy, presented significantly lower GHBP values than controls (P < 0.0001); during treatment, these values increased significantly; however, after 6 months they were still significantly lower than control values (P < 0.01). The pretreatment levels of GH were not significantly different from control values; after 1 month of treatment, GH did not show the decrease observed in controls and, therefore, was significantly higher (P < 0.01). The pretreatment levels of IGF-I were not significantly different from control values, but were lower in patients with severe than in those with mild hypothyroidism. They decreased at about 4 months of life and became significantly lower than control values at about 7 months of age (P < 0.05). In conclusion, it may be hypothesized that the condition of CH induces a change in GHBP expression, perhaps beginning in fetal life. The intrauterine production of IGF-I seems to be independent of the levels of GHBP and partially affected by fetal thyroid function.

Abstract
In Italy, oral polio vaccine and diphtheria and tetanus (DT) and hepatitis B (HB) vaccinations are required by law. At present, infants receive DT and HB by two separate intramuscular injections during one visit, and most receive an additional injection of acellular pertussis vaccine at the same time. Although simultaneous administration of the vaccines has the advantage of only one medical visit, it is time-consuming for staff, very expensive, painful to the infants, and stressful for parents. A much better solution would be to administer a ready-to-use mixture containing all the vaccines, provided that this combination vaccine had good local and systemic safety profiles and clinical and immunologic efficacy. To evaluate such a combination vaccine in healthy infants at 3, 5, and 11 and at 2, 4, and 6 months of age, a multicenter clinical study is underway in Italy.

Abstract
The influence of dietary long chain polyunsaturated fatty acid (LCP) supply, and especially of docosahexaenoic acid (DHA), on evoked potential maturation, was studied in 58 healthy preterm infants using flash visual evoked potentials (VEPs), flash electroretinography (ERG), and brainstem acoustic evoked potentials (BAEPs) at 52 weeks of postconceptional age. At the same time, the fatty acid composition of red blood cell membranes was examined. The infants were fed on breast milk (n = 12), a preterm formula supplemented with LCP (PF-LCP) (n = 21), or a traditional preterm formula (PF) (n = 25). In the breast milk and PF-LCP groups the morphology and latencies of the waves that reflect the visual projecting system were similar; in the PF group the morphology was quite different and the wave latencies were significantly longer. This could mean that the maturation pattern of VEPs in preterm infants who did not receive LCP was slower. Moreover, a higher level of erythrocyte LCP, especially DHA, was found in breast milk and PF-LCP groups compared with the PF group. ERG and BAEP recordings were the same in all three groups. These results suggest that a well balanced LCP supplement in preterm formulas can positively influence the maturation of visual evoked potentials in preterm infants when breast milk is not available.

Abstract
This study reports the Hb, erythropoietin (Epo), and reticulocyte course at different postnatal ages (range, 8-83 d) of 56 blood samples from 30 newborns (range, one or two blood samples from each newborn) with erythroblastosis fetalis (18 intrauterine transfused (IUTd) and 12 non-IUTd). Hb, Epo, and reticulocyte values were not statistically different in IUTd and non-IUTd cases. As age increased, decreasing Hb values and increasing Epo levels were observed. The reticulocyte count was relatively low in all but six cases. There was an inverse correlation between Epo and Hb (r = -55, p < 0.001), but no correlation was found between Hb and reticulocytes or between Epo and reticulocytes. When groups were formed on the basis of Hb levels, anemic newborns showed higher serum Epo than did nonanemic patients (p < 0.02). In the present study we found a significant increase in Epo levels in anemic newborns without a rise in the reticulocyte count. These results suggest that other mechanisms, rather than low Epo production, could be involved in the pathogenesis of this anemia. Persisting anti-D antibodies, probably at a medullary level, may destroy erythrocyte precusors, leading to anemia with a low reticulocyte count.

Abstract
Agenesis of the corpus callosum was identified by ultrasound examination in 35 fetuses between 19 and 37 weeks' gestation. The ultrasound findings included absence of the corpus callosum and cavum septum pellucidum (hypoplasia in one case of partial agenesis of the corpus callosum), a typical 'teardrop' configuration of the lateral ventricles, distension of the interhemispheric fissure, upward displacement of the third ventricle, radiate arrangement of the medial cerebral gyri, and abnormal branching of the anterior cerebral artery. Associated anomalies were identified in 20 fetuses, including heterogeneous malformations and chromosomal aberrations (mosaic-trisomy 8 in three, trisomy 18 in two and partial duplication 8p in one). Five cases of agenesis of the corpus callosum were identified in a population of pregnant patients prospectively investigated because of genetic risk for agenesis of the corpus callosum or related syndromes. In this group, no diagnostic errors were made. Long-term neurological follow-up (6 months to 11 years) was available in 11 infants with antenatal diagnosis of isolated agenesis of the corpus callosum. Normal intellectual development was present in nine, and a low intellect (developmental quotient between 70 and 85) was found in two. It is concluded that fetal agencies of the corpus callosum is associated with elusive sonographic findings that can, however, be accurately identified by targeted examinations. In routine sonograms, an increased atrial width and/or failure to visualize the cavum septum pellucidum should arise the suspicion of fetal agencies of the corpus callosum. Given the high frequency of associated anomalies, prenatal diagnosis of agencies of the corpus callosum dictates the need for a careful survey of fetal anatomy and karyotyping. The prognosis is isolated agencies of the corpus callosum remains uncertain, although it is expected that a normal or boarderline intellectual development will occur in many cases.

Abstract
The influence of antiepileptic drug (AED) therapy on total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and triglycerides was studied in 208 epileptic children compared with 175 normal children. A significant increase in TC plasma levels was observed with carbamazepine (CBZ), phenobarbital (PB), and phenytoin (PHT). The patients receiving valproate (VPA) showed levels very similar to those of the control population. The results may be explainable by the different biotransformation pathway of these drugs. HDL cholesterol and triglycerides were not altered by any of the AEDs. We recommend monitoring TC level in patients receiving CBZ, PB, and PHT and prescription of diet treatment, at least during the time of AED treatment.

Abstract
Lobar holoprosencephaly was identified with sonography in 12 fetuses between 21 and 35 weeks' gestation. A confident diagnosis was made in each case by a mid-coronal view of the brain demonstrating absence of the cavum septum pellucidum with fusion and squaring of the frontal horns. The only associated anomaly was Dandy-Walker malformation that occurred in three cases. All fetuses had mild to severe ventriculomegaly. Five pregnancies were terminated; there was one spontaneous abortion and six fetuses were delivered at term. A ventriculo-peritoneal shunt was implanted in four. Follow-up was available for five and revealed severe mental retardation in each case. Lobar holoprosencephaly is amenable to prenatal ultrasound diagnosis, although a differentiation with other cerebral malformations may be difficult at times. The outcome of affected infants remains uncertain, but neurological impairment occurs frequently.

Abstract
A multicentre study was carried out in a sample population of healthy volunteers in order to assess the usefulness of assaying serum ferritin to monitor the extent of reserves in subjects with a risk of iron deficiency. A total of 317 subjects were included in the study. Ninety-nine were children with a mean age of 19 months, 121 were adolescents with a mean age of 18 years and 7 months, and 97 were women with a mean age of 28 years and 9 months. Levels of serum ferritin below the normal minimum levels for each age bracket, an indication of the exhaustion of the body's reserves, were found in 29% of children, 32.2% of adolescents and 27.8% of women. This study therefore confirm the frequent onset, even in our modern society, of iron-deficient states at particular times of life and that these are easily overlooked. The measurements of serum ferritin levels, in addition to being a confirmatory test in cases of suspected sideropenic anemia, has the peculiar characteristic of being the only test able to identify risk subjects before they become symptomatic. This enables rapid treatment to be commenced or better, efficient prevention.

Abstract
A 27-year-old primigravida women was referred for ultrasound studies at 32 weeks' gestation because of the suspicion of fetal ventriculomegaly. Sonographic examination of the fetal brain found a marked shift of the midline, with enlarged left hemisphere and ipsilateral occipital horn, and abnormal convolutions. A 3500 gm male infant was delivered by cesarean section at 39 weeks' gestation because of worsening macrocrania after which the diagnosis of unilateral megalencephaly was confirmed by computed tomography.

Abstract
The AA studied 406 newborn babies during the 1st year of life in order to verify the correlation between atopy risk factors and the appearance of early symptoms, particularly gastroenteric (GE). The results obtained did not demonstrate a significant difference concerning the blood cord IgE level and subsequent appearance of food allergy symptoms, whereas positive familiarity showed a better correlation. No significant difference was observed between breast--or formula--fed infants, or between those weaned before or after the 5th month of life. The comparison of dietary regimen adopted during the 1st quarter in the asymptomatic and atopic children respectively, demonstrated that the presence of predisposing factors influences the appearance of GE symptoms much more than the diet in itself. An allergologic study, randomly performed by Prick-test in 156 cases and by RAST in 200 cases, showed a prevalent, positive response with RAST technique in symptomatic children.

Abstract
Epidemiological and genetic variables in clefts were analyzed during the years 1978-1986 in a case-control study of congenital malformations in the Emilia Romagna region of northern Italy. Among 150,168 newborns, 200 cases of cleft were detected, yielding a prevalence of 1.33 per 1,000. These clefts consisted of 112 (0.075%) cases of cleft lip with or without cleft palate (CL +/- P) and 88 cases (0.058%) of cleft palate (CP). Coexisting abnormalities were found in 32% of cases. The heritability coefficient of CL +/- P was 0.84. No cluster in time or space could be demonstrated. Epilepsy was the only maternal risk factor found to be correlated with clefts. A predominance of males was found among CL +/- P cases.

Abstract
The sonographic findings in nine cases of agenesis of the corpus callosum examined before and after birth are reported. Agenesis of the corpus callosum was suspected in utero due to a typical configuration of the lateral ventricles, which included enlargement of the atria and occipital horns and marked separation of the bodies. In three cases pregnancy was terminated because of severe associated anomalies. In the remaining six cases postnatal ultrasound examination allowed a certain diagnosis by demonstrating the abnormal configuration of the lateral ventricles, varying degrees of enlargement, and upward displacement of the third ventricle and absence of the corpus callosum.

Abstract
Craniopagus twinning is an extremely uncommon birth defect with an estimated incidence of 4-6 every 10 million births. The most complex and challenging issue is the feasibility of surgical separation, which involves not only technical but also socioethical problems and requires strict multidisciplinary cooperation between pediatricians, neuroradiologists, anesthesiologists, and plastic and neurological surgeons. The authors report a case in which separation was followed by the death of both twins and stress the importance, from the surgical and prognostic viewpoints, of the degree of vascular connections between the major dural sinuses. We propose a classification into three types according to severity.

Abstract
We investigated the effect of prolonged iron supplementation of low birthweight infants on plasma zinc concentrations. Thirty infants (neonatal weight 820-2000 g) were examined at 6 or 12 months of life to assess their iron state and plasma zinc concentration. All of them were feeding on iron fortified formulas, which supply about 1 mg/kg/day of iron. In addition, 14 of them had been receiving 2 mg/kg/day of medicinal ferrous salts for at least five months. The other 16 were not given medicinal iron supplementation. Whereas iron state significantly differed in the two groups, plasma zinc concentrations were similar. Moreover, no zinc values below 75 micrograms/100 ml were found in any case. The results suggest that long term iron supplementation of low birthweight infants, at the recommended doses, does not influence zinc plasma concentrations unfavourably.

Abstract
In connection with the surveillance programme of congenital malformations in Emilia Romagna led by I.M.E.R. Group since 1978 a crosswise survey has been performed on selected malformations: Down's syndrome, cardiac defects, unilateral or bilateral cleft lip and/or palate, unilateral or bilateral club foot. This survey has been useful as a pilot-study for another longitudinal survey which had a place in the programmes of the C.N.R. (National Research Council). By means of a multi-discipline approach we have collected information both of pediatric and of psycho-social character. A total of 187 children with the above named malformations were recorded at birth, 106 boys and 81 girls, aged from 9 months to 4 years. The neonatal diagnosis was confirmed in 84 out 86 cases under study. The rate of infant mortality was particularly high among children with heart defects (39.1%) and Down children (27.4%). The surgical centres where these children were operated upon, through with large variations in connection with the type of malformation, were in Emilia Romagna (49%), outside it (40%), and abroad (10.9%). As for the parental reaction to the birth of babies with congenital malformations, it was of initial rejection 5 cases of Down children, 3 cases of cardiopathy and 1 case of cleft lip and palate. Later the refusal was permanently confirmed only in 2 cases of Down children (who were subsequently adopted). The birth of a malformed baby has affected the relationship between husband and wife contributing to the separation in 3 cases of Down's syndrome and in 1 case of cardiopathy.

Abstract
In a multicentric survey carried out in Emilia Romagna area on congenital malformations 1914 babies out of 103484 babies born from 1978-1984 were discovered to have malformations. Out of these malformations cases 17% were found to be affected by genitourinary tract anomalies (GU) divided as follows: 235 genital malformations and 91 urinary tract anomalies. All these GU patients were diagnosed within the first week of life. Genital malformations: Genital malformations are mainly constituted by hypospadias, found in 214 out of 235 babies. Among these babies, 72% have first degree hypospadias, 22.4% have second degree, and only ten babies were found with third degree hypospadias. In this study 4.1 out of 1000 male newborns have been found affected by hypospadias, in agreement with the results of other researches whose values were between 2% and 4.4%. Many different variables (such as parental age, exposure to smoke, alcohol, RX-ray before pregnancy, low birth weight, early age at menarche, exposure to progestins for threatened abortion, shorter gestation) have been considered in order to verify their correlation with the hypospadias, comparing with control group. Among these the most statistically significant are the exposure to progestins for threatened abortion (p less than 0.05), early age at menarche (p less than 0.001) and the intrauterine growth retardation (p less than 0.001). Also these results agree with the previous studies. Urinary tract anomalies: the 93 babies with kidney and-or urinary tract malformations out of 103484 newborns represent the 8.9%. The diagnoses were made or suspected (and later confirmed) during the first week of life.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The mega cisterna magna is a congenital developmental malformation which in the majority of instances is symptomless and does not require further study or surgical treatment. However, differential diagnosis with other cerebellar diseases is often necessary especially in newborn infants. Ultrasonographic recognition of the mega cisterna magna in a newborn infant is reported. The reported case demonstrates the usefulness of the ultrasonographic technique in the study of the posterior cranial fossa abnormalities of newborn infants.

Abstract
Doppler ultrasound investigation of cerebral blood flow velocity was performed in hydrocephalic infants through the anterior fontanelle. Systolic (S) and end-diastolic (D) frequency values recorded on the anterior cerebral artery were used to define the pulsatility index (PI) calculated from the equation PI=S-D/S. Comparison between systolic, end-diastolic and pulsatility index values of 50 normal infants and 10 hydrocephalic infants showed a statistically significant difference (P less than 0.05) for systolic and pulsatility index values. However, no significant difference was found for end-diastolic values. The authors believe that the phenomenon could be explained as an increase of the cerebrovascular compliance which counteracts the increase of the perivascular pressure in an attempt to maintain a normal cerebral blood flow. Therefore, the transfontanelle Doppler ultrasound technique may provide a useful and early tool in diagnosing cerebral blood-flow changes in hydrocephalic infants.

Abstract
Red cell free erythrocyte porphyrin and serum ferritin determinations were performed on capillary blood specimens from 63 healthy infants weighing 2500 g or less at birth, during the first week of life, and, from 44 of them, again at 8-10 weeks. Free erythrocyte porphyrin values were high both at 3-7 days (mean 156 microgram/100 ml RBC) and at 8-10 weeks (mean 128 microgram/100 ml RBC). The respective serum ferritin values were also high (mean 226 and 107 ng/ml), excluding a depletion in iron stores. In addition, no correlation was found between free erythrocyte porphyrin and serum ferritin values either at birth or at age 2 months. These findings are consistent with an earlier hypothesis that in the presence of iron stores, the rate of iron release from the stores in low birthweight infants may not be sufficient to maintain optimal erythropoiesis if the demand is accelerated.
