Abstract
Smartphones in medical settings pose infection risks due to harbouring pathogenic bacteria. This pilot study assesses the effectiveness duration of sanitisation methods, focusing on 70% isopropyl alcohol wipes and UVC boxes, aiming to obtain preliminary data on the reduction in Total Bacterial Load 3 hours post-sanitisation. A randomised monocentric trial with two intervention arms (wipes and UVC boxes) was designed. As participants, healthcare workers from three wards at Fondazione Policlinico Universitario "A. Gemelli" IRCCS Hospital were recruited, stratified by ward, and block randomised within each ward to control confounders. Seventy-one healthcare workers, mostly nurses (62%) were included in the study. Initial bacterial load reduction was significant with both disinfection techniques, but after 3 hours both methods showed increased bacterial levels, with wipes displaying potentially higher residual efficacy (p=0.056). To adequately size a trial (89% power, significance level 0.05) for assessing the residual efficacy of alcohol-impregnated wipes compared to UVC boxes at 3 hours post-sanitisation, 503 professionals per group were required. This study highlights the necessity for guidelines on hospital smartphone sanitisation and educational initiatives for healthcare workers and patients. Further studies, adequately sized, are necessary to determine optimal sanitisation intervals and assess pathogen transmission risks.

Abstract
Late-preterm infants (LPT) are at increased risk for long-term neurodevelopmental sequelae and iron deficiency. The aim of the study is to assess the positive effect of iron supplementation on psychomotor development in healthy LPT. We designed a randomized placebo-controlled double-blind trial dividing the newborns into two groups. Every patient was assessed using the Griffiths Mental Development Scales (GMDS)-II edition at 12-month post-conceptional age. The study was performed at the Neonatology Unit of our Hospital, in Italy. Sixty-six healthy LPT infants born between 340⁄7 and 366⁄7 weeks of gestational age were enrolled in the study. One group received martial prophylaxis from the third week of life to 6 months of post-conceptional age (2 mg/kg/day of iron pidolate), the other received placebo. Fifty-two of the enrolled infants were assessed using the GMDS at 12-month of post-conceptional age. Statistical analysis of the mean scores of the Griffiths subscales was performed. There was a difference in the mean developmental quotient (DQ) (p < 0.01) between the two groups: iron group mean DQ 121.45 ± 10.53 vs placebo group mean DQ 113.25 ± 9.70. Moreover, mean scores of the Griffiths subscales A, B, and D showed significant differences between the two groups (scale A p < 0.05, scale B p < 0.02, scale D p < 0.01, respectively).Conclusions: We recommend that all LPT neonates receive iron supplementation during the first 6 months of life in order to improve their 1-year neurodevelopmental quotient. What is Known: • Late-preterm infants (LPT) are at increased risk for long-term neurodevelopmental sequelae and also for iron deficiency. • Iron deficiency is an independent risk factor for adverse neurological outcomes. What is New: • Healthy late-preterm who received iron supplementation during the first 6 months of life achieved better neurological outcomes at 12-month post-conceptional age than LPT who received placebo. • Our study strongly supports the need for the implementation of martial prophylaxis in LPT neonates.

Abstract
BACKGROUND Term neonates (TN) are not routinely submitted to cranial ultrasound scan (CUS), since they are not considered at high risk for developing cerebral lesions. AIMS To investigate the prevalence of cerebral abnormal findings in term neonates (TN), to identify the associated clinical features and to better target neonatal CUS investigations. STUDY DESIGN Prospective observational study. SUBJECTS A total number of 1805 healthy TN underwent CUS. 1181 neonates had clinical features supposed to increase the risk for cerebral abnormal findings (study cohort), 624 were controls. OUTCOME MEASURES Prevalence of minimal, minor, and major cerebral abnormal findings was analyzed in six different categories of low-risk TN and compared to controls. RESULTS Variations from normality at the neonatal CUS were observed in 402 TN (22.27%). In half of the cases the ultrasound findings were minimal abnormal findings, while minor abnormal findings were found in 179 TN (9.92%). About 1% of the studied neonates showed major cerebral abnormal findings potentially compromising neurodevelopmental outcome. The prevalence of the observed abnormal findings varied significantly in the different low-risk categories. CONCLUSIONS The clinical features significantly increasing the risk for cerebral anomalies in healthy TN were microcrania, macrocrania, mild neurologic signs, and the detection of mild variations from normal cerebral aspect at the antenatal ultrasound evaluation.

Abstract
This study investigated hearing threshold changes during the first year of corrected age (CA) in infants admitted in a neonatal intensive care unit (NICU). In 5 years, 239 infants with birth weight (BW) ≤ 1,000 gm and/or gestational age (GA) ≤ 30 weeks were enrolled. Hearing was evaluated by oto-acoustic emission (OAEs) before discharge and auditory brainstem response (ABR) within 3 months of CA. Infants affected by unilateral or bilateral hearing loss were addressed to audiological follow-up until definitive diagnosis (within 6 months of CA). Changes in hearing threshold were also carefully analysed. 207 (86.6%) infants had normal hearing while 32 infants (13.4%) showed hearing loss (HL) at the confirmative ABR evaluation (9 mild, 16 moderate, 4 severe, 3 profound). The latter showed lower GA (27.7 ± 2 vs 28.4 ± 1.2; p = 0.0061) and BW (950 ± 390 vs 1,119 ± 326 gm; p = 0.0085). At final evaluation, 15 infants (47%) recovered a normal hearing. HL was confirmed in 17 patients. Among these, 3 infants were addressed to audiological follow-up (one case of mild unilateral hearing loss (UHL) and two with moderate UHL), while in 14 cases (44%) with bilateral sensory neural hearing loss (SNHL) (7 moderate, 4 severe, 3 profound) hearing aids were prescribed. They showed significantly lower GA and longer hospital stay in the NICU in comparison with infants without indication for audiological habilitation (18 infants) (GA 26.2 ± 2.2 weeks vs 28.4 ± 2.4; p = 0.01; NICU stay 132 ± 67 vs 59 ± 7; p = 0.0002). Definitive diagnosis was obtained at 5.9 ± 1.3 months of CA. Our study confirms the importance of audiological surveillance in preterm newborns. Hearing thresholds of preterm infants with hearing loss can change during the first year of CA and we observed normalisation in 47% of our patients. Most vulnerable to permanent SNHL were very preterm infants with a longer NICU stay, while a shorter stay represents a favourable prognostic factor for hearing improvement.

Abstract
Insulin-like growth factor-1 (IGF-1) is involved in regulating the TH-l/TH-2 balance, favoring the development of the TH-2 compartment which enhances fibrosis, one of the main characteristics of Chronic Lung Disease (CLD) in premature newborns. Limited data is available concerning a possible association between early epithelial lining fluid (ELF) concentrations of IGF-1 (total and free forms), IGF-binding protein-3 (IGFBP-3), b2-microglobulin (B2M) and subsequent development of CLD in preterm neonates. If neutropenic, preterm neonates are frequently treated with recombinant human Granulocyte Colony Stimulating Factor (rhG-CSF). The objective of the study was to correlate ELF concentrations of IGF-1 and B2M during the first week of life both in non-neutropenic and in rhG-CSF-treated neutropenic preterm neonates, with subsequent development in CLD. Thirty preterm neonates with Respiratory Distress Syndrome (6 with neutropenia) were studied. Eleven out of 24 non-neutropenic preterm infants (46%) and all of the six neutropenic subjects (100%) developed CLD. With the exception of first day values, there was a clear similarity in the behaviors of assayed molecules between non-neutropenic and neutropenic patients developing CLD. Non-neutropenic patients without CLD showed significantly lower values of free IGF-1 and B2M both on days 1 and 3. Total IGF-I and cell counts were different only on the 3rd day. Conclusions: 1) the mechanisms leading to CLD might be mediated by high levels of IGF-family molecules soon after birth 2) B2M could be a marker of increased bronchoalveolar lavage fluid cellularity with potential inflammatory properties 3) G-CSF treatment induces an increased synthesis of IGF-1 molecules by cells recruited in the lung, with possible enhancement of the fibrogenic mechanisms.

Abstract
Several studies in the lamb model have shown that hyperinflation of the lungs early in life may cause a blunted response to surfactant with signs of lung injury and any attempt to recruit lung volume in the surfactant deficient preterm infant by large lung inflations at birth should be potentially dangerous. As regards the situation when surfactant is given later, as rescue treatment for established RDS, the evidence for a clinically beneficial effect of a recruitment maneuver is yet insufficient and, hopefully, future studies will gather more data on this aspect.

Abstract
AIM Fluconazole prophylaxis of invasive fungal infections is a cornerstone of neonatal care, but in vitro studies have shown that it inhibits corticosteroid production. This study assessed whether preterm infants demonstrated an association between fluconazole administration, and its duration, and symptoms of adrenocortical insufficiency. METHODS We compared two groups who were treated before and after we introduced the use of fluconazole to our neonatal intensive care unit. Infants with a gestational age of ≤27 weeks or with a birth weight of ≤750 g were considered for the retrospective analysis. In order to assess whether the duration of prophylaxis was related to adrenocortical insufficiency, regression models were performed in all preterm infants in the fluconazole group. RESULTS The fluconazole group (n = 37) and nonfluconazole group (n = 41) were compared. No differences were found in the percentage of infants with symptoms of adrenocortical insufficiency, such as hypotension or need of vasopressor therapy. The incidence of hypotension and the use of vasopressor therapy were not related to duration of fluconazole prophylaxis. CONCLUSION Fluconazole and it duration were not associated with the incidence of symptoms related to adrenocortical insufficiency. Further prospective trials are needed to better define the relationship between fluconazole and adrenocortical insufficiency.

BACKGROUND There is no agreement to define the target FiO2 to adopt in the lung recruitment phase during HFOV in preterm infants. We report our experience of an optimal lung volume strategy (OLVS), defined as FiO2≤0.25 during the recruitment phase, in a cohort of neonates with gestational age (GA) ≤27 weeks treated with elective HFOV for respiratory distress syndrome (RDS) between July 2006 and September 2008. METHODS FiO2 used during the recruitment phase was different according to physician' evaluation. 51 newborns were then divided into two groups: patients reaching FiO2≤0.25 (OLVS Group, N.=28), and patients reaching FiO2>0.25 (No-OLVS Group, N.=23). RESULTS Prior to surfactant administration OLVS Group, respect to No-OLVS Group, received a significantly higher continuous distending pressure (CDP): 12.8±1.1 cmH2O vs 11.2±1.3 cmH2O (P<0.0001) and a significantly lower FiO2: 0.25±0.01 vs 0.35±0.06 (P<0.0001). A multivariate modeling approach confirmed that OLVS was significantly associated to the need for less surfactant doses (OR 0.19[95% CI 0.05-0.84]), a decreased risk of ductus arteriosus surgically ligated (OR 0.13[95% CI 0.02-0.86]) and to a lower number of ventilation hours before extubation: -152 (95% CI -284- -20). CONCLUSION OLVS to fully recruit the lungs achieving FiO2≤0.25 during elective HFOV is associated with better short-term pulmonary outcomes respect to a strategy where the patients received a FiO2>0.25 during the recruitment phase. Utilizing HFOV in this way provides a more effective means to recruit and protect acutely injured lungs.

Abstract
Antimicrobial peptides plays an important role in the host innate defence network, even in humans. Recent studies demonstrated the capacity of human airways epithelial cells to synthesize antimicrobial peptides, and their multifunctional role in the primary immunity. The presence of ct-defensins in bronchoalveolar lavage fluid (BALF) was investigated in a cohort of preterm newborns with gestational age (GA) < or =30 weeks. BALF samples were analysed by High Performance Liquid Chromatography Electrospray Ionization Mass Spectrometer. Our data show that preterm newborns, also at the lower GA, are able to produce defenses, underlining that their innate defence system is already active before the at-term delivery date.

Abstract
Patency of the ductus arteriosus (PDA) and bronchopulmonary dysplasia (BPD) development represent severe affections for premature newborns, therefore the research of early markers for these two conditions is really important. The aim of this study is to analyze epithelial lining fluid (ELF) Neutrophil-gelatinase-associated lipocalin (NGAL) levels for prediction of lung injury or possible involvement of this molecule in PDA. Only scarce and contrasting results have previously been published in this field. In contrast, this molecule, included in a large macromolecular complex together with matrix metalloproteinase-9 (MMP-9), is considered an acceptable marker of infectious/inflammatory processes, cancer monitoring and induction of apoptotic pathway. NGAL was detected in 28 pre-term newborns by means of a commercially available kit in bronchoalveolar lavage fluid (BALF). The results have been corrected to ELF levels, by the urea method, to eliminate bias due to BALF collection. ELF NGAL levels were found significantly increased both in infants developing BPD or in those affected by PDA. By means of multivariate logistic regression analysis the significances were confirmed after adjusting for possible interfering variables such as gestational age and concomitant presence of both PDA and BPD. Our results stress the involvement of NGAL in the mechanisms leading to BPD and also suggest a possible association with PDA, which is often linked to prematurity and BPD development, probably due to the involvement of inflammatory and angiogenetic processes in both pathologies.

Abstract
AIM The aim of this paper was to evaluate usefulness and safety of Meropenem in severe infections in neonatal intensive care unit (NICU) patients. New broad spectrum carbapenem class of -lactam antibiotics has been investigated for the treatment of a wide range of infections, including nosocomial infections with cephalosporin-resistant pathogens, an emergent problem in NICU, and meningitis. Meropenem represents the first cabapenem-class that has received Food and Drug Administration (FDA) approval for use in children 3 months of age and older. The pharmacokinetics of Meropenem has been well studied in preterm neonates. METHODS We report the use of Meropenem in 26 neonates with median gestational age (GA) of 27 weeks (25-32) and median birth weight of 940 g (510-1900), with severe infections due to Gram-negative or Gram-positive organisms, from 2001 to 2004. The median postnatal age was 21 days (4-75). Meropenem was administrated intravenously in 30 min at dosage of 20 mg/kg every 12 h (every 8 h in Pseudomonas Aeruginosa infections). RESULTS In all cases Meropenem has been used as second choice. No adverse effects (eosinophilia, trombocytosis or thrombocytopenia, increase in liver enzyme, increase in creatinine, diarrhea, vomiting and seizures) were observed. Clinical and bacterial response was ontaine in all cases but one. CONCLUSIONS This report suggests that Meropenem may be a useful and safe antimicrobial agent in neonatal infections caused by resistant organisms and in meningitis. Further studies are needed to confirm these results.

Abstract
AIM The aim of this study was to evaluate retrospectively the incidence and etiology of connatal pneumonia and ventilator-associated pneumonia (VAP) in preterm newborns who had birth weight = or < 1250 g and required intubation for at least 12 h. METHODS We have reported data about preterm newborns who had birth weight = or < 1250 g and required intubation for at least 12 h with diagnosis of connatal pneumonia and VAP, admitted to the neonatal intensive care unit from 1994 to 2004. We divided these 11 years into 4 periods. For each period we determined etiology associated with connatal pneumonia or VAP. RESULTS A total of 417 patients were studied; 311 (74.6%) required mechanical ventilation (MV) for more than 48 h (the least for the diagnosis of VAP). Connatal pneumonia occurred in 35/417 patients (8.4%). VAP incidence did not change over time showing a slight increase in the last 2 years (from 27% to 33%). Mycoplasma and Chlamydia as causative organisms of connatal pneumonia dissapear during years. Gram-negative micro-organisms were isolated more frequently in last years in VAP episodes. CONCLUSIONS The incidence of VAP does not decrease over time although length of MV was reduced. Additional studies are needed to improve criteria for the diagnosis and prevention of VAP in NICU patients.

Abstract
UNLABELLED Insulin-like growth factor-1 (IGF-1) is involved in regulating the Th-1/Th-2 balance, favoring the development of the Th-2 compartment which enhances fibrosis, one of the main characteristics of Chronic Lung Disease (CLD) in premature newborns. Limited data is available concerning a possible association between early epithelial lining fluid (ELF) concentrations of IGF-1 (total and free forms), IGF-binding protein-3 (IGFBP-3), beta2-microglobulin and subsequent development of CLD in preterm neonates. If neutropenic, preterm neonates are frequently treated with recombinant human granulocyte colony stimulating factor (rhG-CSF). The objective of the study was to correlate ELF concentrations of IGF-1 and beta2 microglobulin during the first week of life both in non-neutropenic and in rhGCSF-treated neutropenic preterm neonates, with subsequent development in CLD. Thirty preterm neonates with Respiratory Distress Syndrome (6 with neutropenia) were studied. Eleven out of 24 non-neutropenic preterm infants (46%) and all of the six neutropenic subjects (100%) developed CLD. With the exception of first day values, there was a clear similarity in the behaviors of assayed molecules between non-neutropenic and neutropenic patients developing CLD. Non-neutropenic patients without CLD showed significantly lower values of free IGF-1 and beta2M both on days 1 and 3. Total IGF-I and cell counts were different only on the 3rd day. CONCLUSIONS 1) the mechanisms leading to CLD might be mediated by high levels of IGF-family molecules soon after birth 2) beta2M could be a marker of increased bronchoalveolar lavage fluid cellularity with potential inflammatory properties 3) G-CSF treatment induces an increased synthesis of IGF-1 molecules by cells recruited in the lung, with possible enhancement of the fibrogenic mechanisms.

Abstract
OBJECTIVE To validate the percentage of time spent below a target value of spontaneous expiratory minute ventilation (< 125 ml/min per kg) during a 2-h period of continuous positive airway pressure (CPAP) via an endotracheal tube (ETT) as a predictor of failed extubation in preterm infants. METHODS Forty-one infants intubated for at least 24 h, with birth weight between 500 and 1000 g, who were clinically stable and at ventilator setting compatible with an extubation attempt, were studied during a 2-h period of ETT CPAP. Dynamic lung compliance and total lung resistance were measured during a period of quiet breathing, while tidal volume (Vt), respiratory rate and the corresponding spontaneous expiratory minute ventilation values were calculated for the complete recording period of 2 h using a customized computer program. The time each patient spent below the target spontaneous expiratory minute ventilation value was reported as a percentage of the total recorded time (% spontaneous expiratory minute ventilation < 125 ml/min per kg). Extubation failure was defined as the need for reintubation within 72 h. RESULTS Eleven out of 41 babies (26.8%) experienced failure of extubation (failure group) while 30 infants (73.2%) were successfully extubated (success group). There were no significant differences in dynamic lung compliance and lung resistance between the two groups, but the mean values of respiratory rate and spontaneous expiratory minute ventilation were significantly lower in the failure group than in the success group: 43 (37-56) breaths/min and 240 (160-353) ml/min per kg vs. 53 (28-67) breaths/min and 309 (223-434) ml/min per kg, respectively (p = 0.0129 and p = 0.0039). Moreover, the babies in whom extubation failed spent a longer time below the target value of spontaneous expiratory minute ventilation when compared with successfully extubated babies (p < 0.0001). Percentage of time spent with spontaneous expiratory minute ventilation < 125 ml/min per kg had a larger area than transcutaneous (Tc)PCO2, TcPO2 and pulse oxymetry saturation (SpO2) under the receiver operator characteristic curves. CONCLUSION The measurement of spontaneous expiratory minute ventilation prior to extubation could be useful in identifying those babies who are not ready for spontaneous ventilation.

Abstract
The changes induced on respiratory mechanics and on tracheobronchial aspirate fluid (TAF) cytology by dexamethasone courses started at two different postnatal ages in preterm infants at risk of chronic lung disease (CLD) were reported in this clinical trial designed in two phases. The first phase of the study included 20 neonates with birth weight < or = 1,250 g and gestational age < or = 32 weeks, who were oxygen and ventilator dependent on the 10th day of life. They were randomly assigned to the moderately early dexamethasone (MED) group or to the control group. The second phase of the study included 20 neonates with the same characteristics, oxygen and ventilator dependent on the 4th day of life, randomly assigned to the early dexamethasone (ED) group or to the control group. Both treated groups received dexamethasone intravenously for 7 days (0.5 mg/kg/day for the first 3 days, 0.25 mg/kg/day for the next 3 days, and 0.125 mg/kg/day for the last day of treatment). The control groups received no steroid treatment. A significantly lower absolute cell count and percentage of neutrophils (PMN) in the TAF and significantly higher dynamic lung compliance (Cdyn) values were observed in both the MED treated compared to the untreated infants and the ED treated infants compared to the control group. Moreover these changes were more precocious in the ED Group compared to the MED Group. Our study suggests that dexamethasone could be more efficacious in reducing effects of ventilator-induced lung injury in preterm infants at high risk of CLD when started earlier.

Abstract
OBJECTIVES To verify whether early pulmonary mechanics measurements are useful to predict subsequent bronchopulmonary dysplasia (BPD) and its severity. METHODS Pulmonary mechanics were studied at 3, 5, 7 and 10 days of age in 52 preterm infants with birth weight < 1250 g, affected by respiratory distress syndrome and ventilated for more than 72 h. Pulmonary function was assessed using a previously standardized method based on the measurement of airflow with a Fleisch OO pneumotachograph and airway pressure with a model P7D differential pressure transducer. At 28 days pulmonary outcome was classified into three groups: no BPD, mild BPD (oxygen dependency and hazy lung on X-ray) and severe BPD (oxygen dependency and Northway stage 3/4). RESULTS Of the 52 infants, 39 survived to 28 days: no BPD (11 infants), mild BPD (16 infants) and severe BPD (12 infants). The no-BPD group had significantly higher gestational age and birth weight, fewer males and a lower incidence of patent ductus arteriosus than both BPD groups, while no differences were detected between the BPD groups. Lung compliance was significantly higher in the mild-BPD group than in the severe-BPD group at 7 and 10 days of life (p < 0.01 and p < 0.001, respectively). The corresponding odds ratio confirmed that ventilated infants with lower lung compliance values had a significantly higher probability of developing severe BPD. Respiratory system resistance did not show any predictive value. CONCLUSIONS Our findings indicate that low lung compliance values determined on the 7th and 10th days of life are a reliable predictive tool of the severity of later BPD.

Abstract
UNLABELLED In a prospective study, plasma interleukin-6 (IL-6) and interleukin-10 (IL-10) levels were measured by enzyme-linked immunosorbent assay in 45 premature neonates (25-34 weeks gestational age) with signs and symptoms of suspected sepsis at 0, 12 and 24 h; C-reactive protein (CRP) was measured at 0-24 h after enrolment. Six subjects were excluded due to insufficient blood sampling. The remaining 39 neonates were assigned to one of three groups: 25 newborns with sepsis (blood culture positive), seven with pneumonia (positive results on broncho-alveolar lavage fluid culture and characteristic chest radiography) and seven with necrotising enterocolitis (NEC) (characteristic intestinal and radiological signs according to the criteria of Bell et al.). A group of 20 healthy preterm neonates represented control subjects. On admission, higher levels of IL-6, IL-10 and CRP were observed in neonates with sepsis: IL-6 (median 1500 pg/ml, range 487-10000 pg/ml), IL-10 (median 113 pg/ml, range 70-196 pg/ml), CRP (median 22 mg/l, range 4-80 mg/l); pneumonia: IL-6 (median 1500 pg/ml, range 747-8000 pg/ml, IL-10 (median 84 pg/ml, range 76-92 pg/ml), CRP (median 10 mg/l, range 8-33 mg/l) and NEC: IL-6 (median 6650 pg/ml, range 1595-7950 pg/ml), IL-10 (median 80 pg/ml, range 61-147 pg/ml), CRP (median 3 mg/l, range 2.8-8 mg/l) as compared to controls (IL-6 median 208 pg/ml, range 198-349 pg/ml; IL-10 median 36 pg/ml, range 19-50 pg/ml; CRP median < 2 mg/l) (P < 0.05). In neonates with sepsis, IL-6 levels were significantly correlated with IL-10 levels (r = 0.65; P = 0.04) at the time of the second sample. The highest IL-6 levels were observed at onset, while IL-10 was predominant 12 h later. On admission, IL-10 and CRP levels were significantly higher in non-survivors (IL-10 median 507 pg/ml, range 422-753 pg/ml; CRP median 123 mg/l, range 20-219 mg/l) than in survivors (IL-10 median 76 pg/ml, range 61-143 pg/ml; CRP median 8 mg/l range 3-46 mg/l), while IL-10 levels were significantly higher (P < 0.05) also 12 h after admission (non-survivors: IL-10 median 600 pg/ml, range 538-800 pg/ml; survivors: IL-10 median 74 pg/ml, range 53-161 pg/ml). IL-6 and IL-10 levels were significantly correlated with CRP levels on admission (r = 0.45; P = 0.05). CONCLUSION Preterm neonates with sepsis, pneumonia or necrotising enterocolitis showed increased interleukin-6, interleukin-10 and C-reactive protein levels. High interleukin-10 concentration was associated with mortality and could be an early indicator of prognosis.

Abstract
This study was designed to evaluate left ventricle dimensions in preterm infants during the first month of life, in order to define reference values and their correlation with gestational age, birth weight, gender and baseline. Thirty-five infants, gestational age 25-29 (mean 27.9 +/- 1.4) weeks, birth weight 750-1249 (mean 965 +/- 206) g, were measured using echocardiography on days 3, 7, 14, 21 and 28 of life. The following dimensions were measured: end-systolic and end-diastolic interventricular septum thickness, end-systolic and end-diastolic left ventricle posterior wall thickness, end-diastolic and end-systolic left ventricle diameter. A progressive and significant increase of all the left ventricle measurements was observed during the first month of life. Left ventricle dimensions at the first scan (Day 3) correlated with birth weight but not with gestational age and gender. The degree of the increase observed during the first month of life was inversely related to the baseline, suggesting that the smaller the left ventricle is at birth, the higher is its postnatal increase toward dimensions similar to those of term infants. Our study gives reference data about left ventricle dimensions of preterm infants during the first month of life and is helpful when making a diagnosis of left ventricular hypertrophy in these subjects.

Abstract
The purpose of this study was to investigate the usefulness of different molecular typing techniques in the surveillance and control of the spread of extended-spectrum-beta-lactamase-(ESBL) producing Klebsiella pneumoniae in the pediatric department of the "Agostino Gemelli" hospital of the Catholic University in Rome, over a period of nine months. The strains were characterized by ribotyping using HindIII as restriction enzyme and pulsed field gel electrophoresis (PFGE) using XbaI as endonuclease. Sixty six K. pneumoniae clinical strains were isolated during this period, the first 32 were isolated in the summer of 1998. Among these first isolates, ribotyping generated 26 different patterns whereas PFGE produced 16 patterns. The remaining 34 strains were isolated during January and April 1999 and all of them were ESBL producers. Ribotyping clustered the strains into 6 patterns whereas PFGE generated only 3 patterns. PCR revealed the presence in 10 isolates of both bla(TEM) and bla(SHV) genes and 24 strains carried only the bla(SHV) gene. In our experience ribotyping revealed a higher power of differentiation with respect to PFGE and was of great help in the surveillance of the infection.

Abstract
The effect of O2 exposure, expressed by mean daily fractional inspired oxygen concentration (FiO2), was evaluated during the first 6 d of life in the tracheobronchial aspirate fluid of 16 mechanically ventilated preterm infants in terms of both antioxidant response and oxidative damage, by measuring total antioxidant activity, uric acid concentrations and protein carbonyl content. Each day linear regression analysis was performed and a positive correlation was found between total antioxidant activity and FiO2 during the study period, especially on day 2 of life (r = 0.91, p < 0.0001), but uric acid correlated only in the first 3 d, especially on the 2nd day (r = 0.83, p < 0.0001). No correlation was found between carbonyl content and FiO2. The highest values of total antioxidant activity (416 and 790 micromol l(-1)) were found in 2 babies ventilated with highest FiO2: 1 and 0.80, respectively. Total antioxidant activity was not detectable or was very low in the babies not requiring O2 therapy. The highest value of uric acid (270 micromol l(-1)) was found in the baby ventilated with 100% oxygen. Uric acid concentrations obtained in these babies were much higher then those reported in the bronchoalveolar lavage fluid of adults. Preterm babies seem to have an antioxidant response in the tracheobronchial aspirate fluid following an oxidative stress and uric acid may be physiologically important as an antioxidant of the respiratory tract, especially during the first days of life.

Abstract
A randomized study was designed to evaluate the effects of two different dexamethasone courses on the growth of preterm infants. The first phase included 30 preterm infants at high risk for chronic lung disease (CLD). 15 babies (moderately early dexamethasone group) were treated with dexamethasone for 14 days, from the 10th day of life, and received a total dose of 4.75 mg/kg; 15 babies were assigned to the control group. The second phase included 30 preterm infants at high risk for CLD. 15 babies (early dexamethasone group) were treated with dexamethasone for 7 days, from the 4th day of life, and received a total dose of 2.38 mg/kg; 15 babies were assigned to the control group. All the main clinical baseline characteristics were similar between the groups both in the first and in the second phase. Infants given the two dexamethasone courses showed significantly reduced weight gain during the period of treatment when compared to the respective control group, but they had a weight catch-up soon after the end of treatment. At 30 days of life the weight and length gain of each treated group were similar to those of control infants, but the moderately early dexamethasone group showed a significantly poorer head growth. No differences between the groups were observed at discharge. Dexamethasone treatment induces a slower weight gain which is time-limited to the period of treatment and is followed by a body weight catch-up. However, the poorer head growth detected at 30 days of life in the infants who received a higher dose of dexamethasone could indicate important adverse effects, possibly dose-related, on postnatal brain growth and development.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effect of early administration of dexamethasone on the incidence of chronic lung disease (CLD) in high risk preterm infants and to evaluate the side effects of the early steroid administration. DESIGN Randomised clinical trial. SETTING Neonatal intensive care unit. PATIENTS 50 infants at high risk of CLD were randomly assigned after 72 h of life to the dexamethasone group (n = 25) or to the control group (n = 25). The treated infants received dexamethasone intravenously from the 4th day of life for 7 days (0.5 mg/kg per day for the first 3 days, 0.25 mg/kg per day for the next 3 days and 0.125 mg/kg per day on the 7th day). The control group received no steroid treatment. RESULTS The incidence of CLD at 28 days of life and at 36 weeks' postconceptional age was significantly lower in the dexamethasone group than in the control group (p < 0.001). Moreover, infants in the dexamethasone group remained intubated and required oxygen therapy for a shorter period than those in the control group (p < 0.001). Hyperglycaemia, hypertension, growth failure and mainly hypertrophy of the left ventricle were the transient side effects associated with early steroid administration. CONCLUSIONS Early dexamethasone administration may be useful in preventing CLD, but its use should prudently be restricted to preterm infants at high risk of CLD.

Abstract
BACKGROUND The objective of this work was to evaluate the utility and the effectiveness of the intraparenchymatous balloon tamponade for transfixing lesions of the liver. An analysis is made of the results of an experimental surgical technique during 12 months in patients with gunshot wounds producing hepatic transfixing lesions. METHODS Twelve patients have been treated, all of masculine sex, with middle age of 22 years, in which the hepatic transfixing lesions have been treated with intraparenchymatous balloon tamponade built intraoperatively with Nelaton and a drain of great latex. This system is filled with physiological solution and hydrosoluble contrast medium for further radiological controls. All the patients have been enrolled at the department of General Surgery of the Hospital "José Maria Vargas" of Caracas (Central University of Venezuela). RESULTS This method has been used with good results, without postoperative bleeding and neither after the balloon removal. CONCLUSIONS The intraparenchymatous balloon tamponade in the hepatic transfixing lesions is a sure procedure, rapid and easy, particularly in the emergency rooms of countries that have a high index of abdominal trauma with gunshot wounds and they are not always endowed with all the surgical medical requirements to treat these severe and difficult hepatic lesions.

Abstract
BACKGROUND The objective of this study was to determine if the value of respiratory system compliance and lung resistance could be a good predictor of chronic lung disease (CLD) in an early stage of this disease. METHODS The study was carried out on 48 preterms infant (BW < 1500 g) who were ventilated for respiratory distress, calculating pulmonary mechanics at 3, 5, 7 and 10 days of life with a standardized protocol of measurements. RESULTS Infants who did not develop CLD showed higher values of respiratory system dynamic compliance (Crsdyn) than the CLD group since the 5th day of life (p < 0.001). The values of lung resistance show a statistical significant difference between groups since the 7th day of life. CONCLUSIONS These findings indicate that, with a well standardized method of measurements, the value of Crsdyn can well be a good predictor and a sensible prognostic factors for CLD.

Abstract
OBJECTIVE The purpose of this study was to develop and validate an empirical scoring system to predict the evolution of neonatal respiratory distress syndrome (RDS) into chronic lung disease (CLD) in preterm infants, by comparing it with a more complicated logistic regression model. DESIGN Clinical study. SETTING Neonatal intensive care unit. PATIENTS The retrospective analysis of a 3-year experience showed that a gestational age (GA) of less than 30 weeks, a birth weight (BW) of less than 1000 g, the diagnosis of hyaline membrane disease (HMD) and pulmonary interstitial emphysema (PIE) during the first 72 h of life, the peak inspiratory pressure (PIP) and the fraction of inspired oxygen (FIO2) were the highest relative risk factors correlated with the evolution of CLD. On this basis an empirical and a statistical scoring system were defined and prospectively applied at 3 and 5 days of life to 228 neonates with BW less than 1,250 g. The results obtained with both scoring systems were then compared. RESULTS Of the 149 infants surviving at 28 days of life, 67 (GA: 29.9 +/- 2.3 weeks; BW: 1,058 +/- 143 g) were normal and 82 (GA: 27.5 +/- 3.9 weeks: BW: 838 +/- 200 g) had CLD. Using a cut-off value of 4.0, the empirical scoring system showed a specificity of 97.0% and a sensitivity of 92.7% on the 3rd day of life; on the 5th day of life the specificity was still 95.5%, while sensitivity remained 92.7%. The areas under the ROC curves plotted with both scoring systems tested were similar. CONCLUSIONS The proposed empirical scoring system is easy to use and is highly reliable. The application of this scoring system provides the opportunity to direct aggressive treatment for CLD toward only very high risk patients between the 3rd and 5th days of life.

Abstract
Osteopenia is a metabolic bone disease which affects a great deal of preterm infants. X-Ray evaluation is still the main step of the diagnostic and follow-up procedures. The Authors prospectively studied 77 newborn infants with birth weight less than 2500 grams, to identify specific clinical and biochemical features of the osteopenic infants. From the 2nd to the 12th week of life clinical, biochemical and radiological signs of osteopenia were looked for, every 2 weeks: the diagnosis of osteopenia was made on the basis of X-Ray. 26 osteopenic subjects with ga less than or equal to 32 weeks and/or bw less than or equal to 1500 grams were compared with 20 controls with ga less than or equal to 32 weeks and/or bw less than or equal to 1500 grams and with 31 control infants with ga greater than 32 weeks and bw greater than 1500 grams. Wider anterior funtanels, their progressively increasing dimensions, and craniotabe (with the "ping pong ball" sign) were the most characteristic features, as well as the increasing pattern of alkaline phosphatase activity, of the osteopenic babies. The Authors suggest a specific clinical and biochemical score to make the correct diagnosis and a non invasive follow-up in the osteopenic subjects and to avoid dangerous X-Ray exposure to babies that are not osteopenic.

Abstract
In this paper the Authors report their personal experience of the use of exchange transfusion, secondary to classic indication, in the treatment of neonatal hyperbilirubinemia, in order to: 1) determine the trend over the past wears in the number of exchange transfused neonates, both from a global point of view and in relation to indications; 2) critically assess the risks, in terms of complications and mortality, correlated to exchange transfusion. Four hundred and eighty-eight neonates, who were subjected to 693 exchange transfusions in the Pediatric Clinic and Neonatal Division of the Policlinico Gemelli in Roma, were studied over a period of 15 years (1972-1986), according to the following indications: 214 cases of neonatal hyperbilirubinemia with MEN-Rh, 106 cases of neonatal hyperbilirubinemia with MEN-ABO and 168 cases of idiopathic hyperbilirubinemia. The total number of exchange transfused neonates decreased drastically from 304 in the period 1972-76 to 65 in the period 1982-86. The frequency of exchange transfused neonates because of idiopathic hyperbilirubinemia decreased significantly (p greater than 0.001), booth in comparison to the number of live births and in comparison to the number of exchange transfused neonates, probably due to the gradual introduction of phototherapy. The frequency of exchange transfused neonates with iso-Rh and iso-ABO decreased or remained stationary on account of the confirmed relative lesser efficacy of phototherapy on hemolytic jaundice. With regard to mortality and morbidity, 27 out of 488 neonates died during the neonatal period, but only 4 within six hours of exchange transfusion; the majority of those who died had a reduced gestational age and low birthweight, and were affected by a severe associated pathology.

Abstract
In 120 nursing mothers, the quantity of milk suckled was evaluated during the first days of the puerperium. Measurements of the milk intake were based on the difference between the weights of the neonate before and after each feeding. It was noted that, as the parity of the mother increased, the mean quantity of breast milk suckled/24 hours increased on the 1st, 2nd and 3rd day of the puerperium, as well as during the last 24 hours prior to discharge from the hospital (3rd or 4th post-partum day). Given the importance of a satisfactory flow of breast milk during the first days of the puerperium in the successful initiation of the breast-feeding experience, the authors would like to emphasize the increased risk of failure in the primipara and to suggest that greater attention be given to the effect of maternal parity in programs which promote breast-feeding.
