Abstract
OBJECTIVE The extent of vertical transmission (VT) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from mothers their fetuses or neonates is still uncertain. We aimed to determine the incidence of VT. STUDY DESIGN In this prospective cohort study. All mother diagnosed with SARS-CoV-2 infection at the time of delivery or up to 1 week prior and their neonates, managed in a tertiary referral hospital for pregnancy complicated by coronavirus disease 2019 (COVID-19) in Rome, from April 2 to December 22, 2020, were included. Maternal infection was defined as nasopharyngeal swab test results positive for SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR). Biological samples were collected before, at, and after delivery to test positivity for SARS-CoV-2 RT-PCR and anti-SARS-CoV-2-specific antibodies. RESULTS The cohort included 95 women and 96 neonates with documented SARS-CoV-2 test results. Four neonates (4.2%) tested positive. The incidence of VT, according to the guidance criteria for diagnosing perinatal SARS-CoV-2 infection, was 5.2%. Neonatal symptoms were due to prematurity or fetal distress: symptomatic infants had lower median (min-max) gestational age, 38.1 (29.3-40.6) versus 39.3 (33.9-41.9) weeks (p = 0.036), and 1-minute and 5-minute Apgar scores, 9 (3-9) versus 9 (7-10) (p = 0.036) and 10 (6-10) versus 10 (8-10) (p = 0.012), respectively, than asymptomatic infants and needed more frequent assistance in the delivery room (22.2 vs 2.5%; p = 0.008). Only six (7.1%) neonates had anti-SARS-CoV-2-specific antibodies, despite the ongoing maternal infection. CONCLUSION The incidence of VT is low as is the detection of specific anti-SARS-CoV-2 antibodies in cord blood when infection is contracted late in pregnancy. This would suggest poor protection of infants against horizontal transmission of the virus. KEY POINTS · VT of SARS-CoV-2 from pregnant mothers to fetuses or neonates can be possible.. · In this prospective cohort study, the incidence of VT is found to be 5.2%.. · VT is low but exists..

Abstract
Pericardial effusion (PE) in pediatric population can be asymptomatic or a life-threatening event. Reports on neonates or preterm infants are scarce and generally related to pericardiocentesis of large amounts of PE in emergency situations.We describe a diagnostic pericardiocentesis in a preterm infant with small and loculated pericardial effusion and suspected cardiac mass. We used an ultrasound-guided long-axis in-plane pericardiocentesis technique, with a needle-cannula. The operator obtained a subxiphoid pericardial effusion view with a high frequency linear probe and entered the skin below the tip of the xiphoid process with a 20-gauge closed IV needle-cannula (ViaValve®). The needle was identified in its entirety as it courses through soft tissue up to pericardial sac. The main advantages of this approach are a continuous viewing and angulation of the needle through all planes of the tissue and the use of a small, practical, closed IV needle-cannula with blood control septum to prevent fluid exposure while disconnecting the syringe. This novel approach is easy and safe in neonatal population, for diagnostic or emergency drainages and can be performed at bedside in a neonatal intensive care unit.

Early Respiratory Physiotherapy versus an Individualized Postural Care Program for Reducing Mechanical Ventilation in Preterm Infants: A Randomised Controlled Trial. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1761. [PMID: 38002852 PMCID: PMC10670353 DOI: 10.3390/children10111761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 10/19/2023] [Accepted: 10/27/2023] [Indexed: 11/26/2023]
Abstract
BACKGROUND Tactile stimulation manoeuvres stimulate spontaneous breathing in preterm newborns. The aim of this study is to evaluate the effect of early respiratory physiotherapy on the need for mechanical ventilation during the first week of life in preterm infants with respiratory failure. METHODS This is a monocentric, randomised controlled trial. Preterm infants (gestational age ≤ 30 weeks) not intubated in the delivery room and requiring non-invasive respiratory support at birth were eligible for the study. The intervention group received early respiratory physiotherapy, while the control group received only a daily physiotherapy program (i.e., modifying the infant's posture in accordance with the patient's needs). RESULTS between October 2019 and March 2021, 133 preterm infants were studied, 68 infants in the study group and 65 in routine care. The study group showed a reduction in the need for mechanical ventilation (not statistically significant) and a statistically significant reduction in hemodynamically significant patent ductus arteriosus with respect to the control group (19/68 (28%) vs. 35/65 (54%), respectively, p = 0.03). CONCLUSIONS early respiratory physiotherapy in preterm infants requiring non-invasive respiratory support at birth is safe and has proven to be protective against haemodynamically significant PDA.

Abstract
AIM During the COVID-19 pandemic, restrictive rules were imposed around the world to limit the spread of the virus. The present study aims to investigate how the pandemic and the consequent restrictions have affected the lives and oral health of Italian families with children aged 0-14 years. MATERIALS Through a questionnaire distributed online from December 2020 to March 2021 the following aspects were investigated: family income during the pandemic, fear of the pandemic, dietary habits, perceived risk of infection in a dental practice and perceived children oral health status during the pandemic. CONCLUSION The pandemic has not drastically changed the socio-economic conditions, the dietary habits and the oral health condition of most Italian children. Nevertheless, the pandemic seems to have highlighted significant macro-regional differences regarding the satisfaction with the response of the regional health services to the pandemic. The continuation of the pandemic and the possible socio-economic effects could favour new changes in lifestyles, oral health and discrepancies regarding health care access, which deserve to be the subject of further investigation.

Abstract
OBJECTIVE The study aimed to report a novel coronavirus disease 2019 (COVID-19)-associated multisystem inflammatory syndrome in children (MIS-C) in a neonate found to have an atypical diffuse thickening in coronary artery walls whose diagnosis required a multi-imaging approach. STUDY DESIGN A neonate presented at birth with multiple organ involvement and coronary artery anomalies. A diagnosis of MIS-C associated with COVID-19 was supported by maternal severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection during pregnancy, and by the presence of both immunoglobulin (Ig)-G against SARS-CoV-2 and spike-specific memory B-cells response in the neonatal blood. Other plausible causes of the multiple organ involvement were excluded. RESULT At admission, a severe coronary artery dilatation was identified on echocardiography, supporting the diagnosis of the MIS-C Kawasaki-like disease; however, coronary artery internal diameters were found to be normal using cardiac computed tomography angiography. At discharge, comparing the two imaging techniques each other, the correct diagnosis resulted to be an abnormal thickening in coronary arterial walls. These findings suggest that the inflammatory process affecting the coronary arterial wall in MIS-C could result not only in typical coronary artery lesions such as dilatation of the lumen or aneurysms development but also in abnormal thickening of the coronary artery wall. CONCLUSION Our case provides an alert for pediatric cardiologists about the complexity to assess coronary artery involvement in MIS-C and raises the question that whether an abnormal vascular remodeling, with normal inner diameters, is to be considered like coronary artery dilatation for risk stratification. KEY POINTS · COVID-19 associated MIS-C can present in neonates with multiple organ involvement.. · Coronary artery assessment in neonatal MIS-C could be complex, and a multi-imaging approach could be required.. · Beside the typical coronary artery lesions, such as dilatation of the lumen or aneurysms, also abnormal thickening of the coronary artery wall can occur..

Platelet Count and Volume and Pharmacological Closure with Paracetamol of Ductus Arteriosus in Preterm Infants. CHILDREN 2022; 9:children9010089.

Abstract
Background: Low platelet count might promote resistance to pharmacological closure with indomethacin and ibuprofen of a hemodynamically significant patent ductus arteriosus (hsPDA). However, no studies have investigated if this occurs with paracetamol. Methods: We retrospectively assessed the correlation between platelet count, mean platelet volume (MPV), and plateletcrit (PCT), as well as the effectiveness of paracetamol in closing hsPDA in infants born at 23+0–31+6 weeks of gestation who were treated with 15 mg/kg/6 h of i.v. paracetamol for 3 days. Results: We studied 79 infants: 37 (47%) Had closure after a course of paracetamol and 42 (53%) did not. Platelet count and PCT did not correlate with paracetamol success or failure in closing hsPDA, while MPV was lower at birth (10.7 ± 1.4 vs. 9.5 ± 1.1; p < 0.001) and prior to starting therapy (11.7 ± 1.9 vs. 11.0 ± 1.6; p = 0.079) in refractory infants. Regression analysis confirmed that the low MVP measured prior to starting the treatment increased the risk of hsPDA paracetamol closure failure (OR 1.664, 95% CI 1.153–2.401). Conclusions: The greater MPV correlated positively with the effectiveness of paracetamol in closing hsPDA, while platelet count and PCT did not influence closure rates. Additional studies are needed to confirm our results.

Abstract
INTRODUCTION Ureaplasma (U.) and Mycoplasma (M.) species have been related to pregnancy complications (including preterm birth) and worse neonatal outcomes. The aim of our work is to evaluate neurodevelopmental outcomes in preterm infants born to mothers with Ureaplasma/Mycoplasma colonization during pregnancy. METHODS Preterm infants with gestational age (GA) of ≤ 30 weeks were included in a retrospective follow-up study. To evaluate the effects of maternal vaginal colonization, we divided preterm infants into two groups: exposed and unexposed infants. All infants were assessed at 24 ± 3 months of age using Griffith's Mental Developmental Scales (GMDS). RESULTS Among 254 preterm infants, only 32 infants (12.6%) were exposed to U. /M. colonization during pregnancy. Exposed infants and unexposed ones had a similar Griffith's Developmental Quotient (106 ± 27.2 vs. 108.9 ± 19.5, respectively), without significant differences (p = 0.46). However, exposed infants had a significantly poorer outcome than their unexposed peers in terms of locomotor abilities (100.7 ± 28.3 exposed vs. 111.5 ± 26.1 unexposed, p = 0.03). CONCLUSION For visual and hearing impairment, exposed and unexposed infants had similar incidences of cognitive and motor impairment. However, exposed infants had significantly lower locomotor scores than unexposed peers.

Effects of early respiratory physiotherapy on spontaneous respiratory activity of preterm infants: study protocol for a randomized controlled trial. Trials 2021; 22:492.

Abstract
Background Tactile maneuvers stimulating spontaneous respiratory activity in preterm infants are recommended since birth, but data on how and how often these maneuvers are applied in clinical practice are unknown. In the last years, most preterm newborns with respiratory failure are preferentially managed with non-invasive respiratory support and by stimulating spontaneous respiratory activity from the delivery room and in neonatal intensive care unit (NICU), in order to avoid the risks of intubation and prolonged mechanical ventilation. Methods Preterm infants with gestational age < 31 weeks not intubated in the delivery room and requiring non-invasive respiratory support at birth will be eligible for the study. They will be randomized and allocated to one of two treatment groups: (1) the study group infants will be subject to the technique of respiratory facilitation within the first 24 h of life, according to the reflex stimulations, by the physiotherapist. The newborn is placed in supine decubitus and a slight digital pressure is exerted on a hemithorax. The respiratory facilitation technique will be performed for about three minutes and repeated for a total of 4/6 times in sequence, three times a day until spontaneous respiratory activity is achieved; thus, no respiratory support is required; (2) the control group infants will take part exclusively in the individualized postural care program. They will perform the technique of respiratory facilitation and autogenous drainage. Objective To evaluate the efficacy of early respiratory physiotherapy in reducing the incidence of intubation and mechanical ventilation in the first week of life (primary outcome). Discussion The technique of respiratory facilitation is based on reflex stimulations, applied early to preterm infant. Slight digital pressure is exerted on a “trigger point” of each hemithorax, to stimulate the respiratory activity with subsequent increase of the ipsilateral pulmonary minute ventilation and to facilitate the contralateral pulmonary expansion. This mechanism will determine the concatenation of input to all anatomical structures in relation to the area being treated, to promote spontaneous respiratory activity and reducing work of breathing, avoiding or minimizing the use of invasive respiratory support.

Abstract
AIM Extra-uterine Growth Restriction (EUGR) is common among preterm infants. Two types of EUGR definitions are still now available: cross-sectional definitions and longitudinal ones. In a cohort of very preterm infants, we aimed to evaluate which definition could better predict neurodevelopmental outcomes at 2 years of corrected age. We used Italian Neonatal Study Charts (INeS) growth charts and INTERGROWTH-21st (IG-21) standard charts and compared results. METHOD We restrospectively collected data from clinical charts of 324 preterm newborns with a gestational age ≤30 weeks born from 2012 to 2017. Then we compared forty-eight definitions (24 cross-sectional and 24 longitudinal) of EUGR, in term of neurodevelopmental outcomes at 2 years of corrected age. RESULTS We included in the study 254 preterm infants, whose clinical information met the enrolment criteria. Nineteen out of 48 definitions of EUGR were significantly predictive both for Griffith's Development Quotient (GDQ) and Neurodevelopment Impairment (NDI). Among these, longitudinal definitions appeared to have a higher negative predictive value for NDI than cross-sectional ones. Furthermore, infants with EUGR appeared to have a lower cognitive score than their peers without EUGR. INTERPRETATION A loss of Zs > 1 SDS in weight and head circumference, calculated from when physiological weight loss is over and identified as soon as possible rather than at discharge, better predicts neurodevelopmental outcomes of preterm infants.

Abstract
OBJECTIVE To evaluate the effect of volume guarantee (VG) combined with high-frequency oscillatory ventilation (HFOV) on respiratory and other physiological parameters immediately after lung recruitment and surfactant administration in HFOV elective ventilated extremely low gestational age newborns (ELGAN) with respiratory distress syndrome (RDS). DESIGN Observational study. SETTING Tertiary neonatal intensive care unit. PATIENTS Twenty-two ELGANs of 25.5 ± 1.1 weeks of gestational age requiring invasive mechanical ventilation and surfactant administration for RDS during the first 6 h of life. INTERVENTIONS All infants intubated in delivery room, were managed with elective HFOV and received surfactant after a lung recruitment manoeuver. Eleven infants received HFOV + VG and were compared with a control group of 11 infants receiving HFOV alone. HFOV was delivered in both groups by Dräger Babylog VN500 ventilator (Dräger, Lubeck, Germany). MAIN OUTCOME MEASURES Variations and fluctuations of delivered high-frequency tidal volume (VThf), fluctuation of pressure amplitude (ΔP) and partial pressure of CO2 (pCO2) levels after recruitment manoeuver and immediately after surfactant administration, in HFOV + VG vs. HFOV ventilated infants. RESULTS There were no significant differences in the two groups at starting ventilation with or without VG. The mean applied VThf per kg was 1.7 ± 0.3 ml/kg in the HFOV group and 1.7 ± 0.1 ml/kg in the HFOV + VG group. Thirty minutes after surfactant administration, HFOV group had a significant higher VThf/Kg than HFOV + VG (2.1 ± 0.3 vs. 1.6 ± 0.1 ml/kg, p < 0.0001) with significantly lower pCO2 levels (43.1 ± 3.8 vs. 46.8 ± 1.5 mmHg, p = 0.01), 54.4% of patients having pCO2 below 45 mmHg. Measured post-surfactant ΔP values were higher in HFOV group (17 ± 3 cmH2O) than in HFOV + VG group (13 ± 3 cmH2O, p = 0.01). CONCLUSION HFOV + VG maintains pCO2 levels within target range and reduces VThf delivered variations more consistently than HFOV alone after surfactant administration.

Abstract
Aim This article aims to assess whether perfusion index is significantly different in infants with positive C-reactive protein and/or positive cultures compared with a control group.
Methods This was a prospective observational cohort study. Perfusion index was evaluated in 80 neonates at the start of antibiotic therapy for suspected sepsis. Antibiotic therapy was started based on the antenatal history or the presence of clinical signs of sepsis such as hypo/hyperthermia, feed intolerance, lethargy, hypotonia, irregular cardiac rhythms, bradycardia, cyanosis, apnea, respiratory distress, and metabolic acidosis. A case group of 23 neonates with abnormal C- reactive protein (> 10 mg/L) and/or positive cultures (blood, liquor, or bronchoalveolar lavage cultures) was compared with a control group of 23 neonates.
Results Cases (mean gestational age [GA], 33 ± 5) and controls (mean GA, 33 ± 5) were matched according to the following criteria: GA (±2 weeks), postmenstrual age (±2 weeks), early (< 72 hours), or late (> 72 hours) onset of suspected infection. Mean perfusion index was 0.8 ± 0.3 in the case group and 1.2 ± 0.4 in the control group; p-value of < 0.001.
Conclusions Perfusion index can be considered a noninvasive, reproducible, and easy-to-apply tool for early diagnosis of a neonatal acute inflammation in course of sepsis.

Abstract
The presence of lymph node metastases is the best prognostic factor for predicting relapse or survival in melanoma patients. It has been demonstrated that melanoma metastases spread through the first lymph node(s) draining the tumor (sentinel lymph node, SN) to the lymphatic system and that detection of melanoma cells in peripheral blood directly correlates with prognosis in melanoma. To identify lymph node metastases and circulating melanocytes, we developed a single-step reverse transcriptase-polymerase chain reaction assay (RT-PCR) for detection of two melanoma-specific markers: the tyrosinase gene, which encodes an enzyme associated with melanin synthesis, and melanoma antigen-related T-cells, which are present in tumor infiltrating T-lymphocytes. This method detects two tumor cells in a background of 107 lymphocytes. Thirty patients with stage I–IV cutaneous melanoma entered the study. Blood samples were taken preoperatively, one month after excision of the primary melanoma lesion and the SN or total lymphadenectomy, and before the start of chemotherapy and every three months thereafter in metastatic patients. SNs were collected from 22 patients, bisected and analyzed by RT-PCR and routine pathological and immunohistochemical tests. The preliminary results indicate that RT-PCR for melanoma markers is a sensitive and valuable method for the detection of micrometastases and for early diagnosis and staging of melanoma.

Abstract
AIM The aim of the present study was to monitor the internal training load and profile of mood states (POMS) during a training camp in junior-elite triathletes. METHODS Sixteen (10 male and 6 female) young triathlon athletes (junior-elite: 18±1 yrs) were included in this study. All triathletes had been training for 7±3 years, and regularly trained 4 times a week 3h per session, throughout the year. The training camp (5 days) included two daily supervised training sessions. The CR-10RPE scale was used 30 minutes after every training session to evaluate session-RPE. POMS was administered 3 times during the training camp: at the beginning, on the 3rd day, and at the end of training camp. RESULTS Session-RPE throughout the different training days showed significant differences (P<0.001). POMS scores showed a significant increase (P<0.001) in fatigue from the first (7.8±1.4), to the third (10.5±2.2) and to the last day of training (14.2±3.4). At the end of the camp, lower (P<0.01) vigour values (12.7±2.8) emerged with respect to the first day (15.8±3.0), whereas anger decreased (P=0.015) the last day (8.6±2.2) with respect to the intermediate evaluation (9.6±2.7). CONCLUSION The 45% increase in fatigue, the 24% decrease in vigour, and the intraindividual variability in session RPE that emerged, indicates that young triathletes need to be monitored closely during training camps in order to individualize training to avoid training maladaptation such as non-functional overreaching.

Abstract
Non-small cell lung cancer (NSCLC) accounts for ∼80% of all lung cancers. Although some advances in lung cancer therapy have been made, patient survival is still quite poor. Two microRNAs, miR-221 and miR-222, upregulated by the MET proto-oncogene, have been already described to enhance cell survival and to induce TNF-related apoptosis-inducing ligand (TRAIL) resistance in NSCLC cell lines, through the downregulation of p27(kip1), PTEN and TIMP3. Here, we further investigated this pathway and showed that miR-130a, expressed at low level in lung cancer cell lines, by targeting MET was able to reduce TRAIL resistance in NSCLC cells through the c-Jun-mediated downregulation of miR-221 and miR-222. Moreover, we found that miR-130a reduced migratory capacity of NSCLC. A better understanding of MET-miR-221 and 222 axis regulation in drug resistance is the key in developing new strategies in NSCLC therapy.

Abstract
OBJECTIVE Serum thyroglobulin (Tg) represents a highly specific biomarker for detecting residual thyroid tissue/recurrence/metastases after treatment for differentiated thyroid cancer (DTC). We evaluated the clinical impact of a highly sensitive Tg assay during routine follow-up of DTC patients. DESIGN Tg values were measured by a highly sensitive Tg assay during L-T4 suppressive therapy and after recombinant human thyrotropin (rh-TSH) stimulation and were compared with those obtained by using a routinely employed Tg assay. PATIENTS One hundred and sixty consecutive DTC-treated patients (papillary carcinoma n = 124, follicular carcinoma n = 36) were studied. MEASUREMENTS Measured variables included neck ultrasonography, (131)I whole body scanning, and Tg assayed by Immulite (Diagnostic Products Corporation, Los Angeles, CA) and by the highly sensitive Access assay (Beckman Coulter, Brea, CA). RESULTS During L-T4 therapy, measurable Tg was found in only two patients (1% of total) by Immulite and in 23 patients (14% of total) by Access assay. Using the institutional cut-off of 2 microg/l after rh-TSH, a negative response was associated with undetectable Immulite Tg during L-T4 therapy in all patients (negative predictive value, NPV, 100%) and in 137 out of 152 patients with Access assay (NPV 90%). Measurable Tg during L-T4 therapy was found in 17% of positive patients with Immulite and in 100% of patients with Access, respectively. CONCLUSIONS The use of a highly sensitive Tg assay may represent a useful diagnostic tool for improving the interpretation of Tg results during monitoring of DTC-treated patients for the early detection of recurrence and for optimizing the use of the more expensive rh-TSH test.

Abstract
Dopamine (DA) and somatostatin (SRIF) receptor agonists inhibit growth hormone (GH) secretion by pituitary adenomas. We investigated DA subtype 2 receptor (DR2) and SRIF receptor (sst) subtypes 2 and 5 expression in 25 GH-secreting pituitary adenomas and tested in primary culture the effects on GH and prolactin (PRL) secretion of sst agonists selectively interacting with sst2 (BIM-23120), sst5 (BIM-23206), and sst2 and sst5 (BIM-23244). All adenomas expressed sst2; eight adenomas expressed both sst5 and DR2, eight sst5 but not DR2, and eight DR2 but not sst5. One tissue lacked expression of DR2 and sst5. GH secretion was inhibited by BIM-23120 in all samples, while it was reduced by BIM-23206 only in adenomas not expressing DR2. BIM-23120's inhibitory effects correlated with sst2 and DR2 expression, whereas DR2 expression correlated inversely with BIM-23206 inhibitory effects on GH secretion. In seven mixed GH-/PRL-secreting pituitary adenomas, PRL secretion was inhibited in sst5-expressing tumors by BIM-23206, but not by BIM-23120. BIM-23244 reduced PRL secretion only in adenomas expressing sst2, sst5 and DR2. sst5 and DR2 expression correlated directly with BIM23206 inhibitory effects on PRL secretion. Our results suggest that adenomas expressing DR2 are less likely to respond to clinically available SRIF analogs in terms of GH secretion inhibition. Therefore, drugs interacting also with DR2 might better control secretion of pituitary adenomas.

Abstract
The determination of serum thyroglobulin (Tg) is commonly used for detecting the presence of residual thyroid tissue or cancer recurrence in patients treated for differentiated thyroid cancer (DTC). The aim of the study was to evaluate the performance characteristics of a recently introduced fully automated chemiluminescent immunoassay, based on four monoclonal antibodies and which produces results in 40 min. Analytical sensitivity (0.01 micro g/l) was computed from 20 replicates of the zero calibrator and of the 'Tg-free' sample pool. Functional sensitivity (0.1 micro g/l at 20 coefficients of variation percent) was determined from the imprecision profile obtained by assaying ten serum pools. The reliability of the measurements in the low concentration range (Tg<1 micro g/l) has been checked by progressive dilution with the 'Tg-free' serum of a sample pool at 5.27 micro g/l; measured values were very close to the expected values (recovery 100-133%).Cut-off at the 99th percentile in DTC stage I 'disease-free' treated patients (n=53) was 0.16 micro g/l. Tg measurement in basal conditions during L-thyroxine suppression therapy and 5 days after recombinant human TSH stimulation was performed in 22 patients with DTC. In 80% of patients with basal Tg<0.1 micro g/l (12/15), Tg remained<0.1 micro g/l after stimulation, and in all of these Tg was<1 micro g/l. Our results have indicated the optimal analytical and clinical performance of this Tg immunoassay and encourage further studies on larger populations of patients with DTC.

Abstract
PURPOSE The purpose of this study was to evaluate the effect of different surgical variables, such as perfusion duration and number of grafts, on resistance and reactance, in heart surgery patients. METHODS 77 patients submitted to coronary artery bypass were studied. The variable concerning time of extracorporeal circulation was classified in four progressive degrees. Resistance and reactance measurements were performed and compared to time of extracorporeal circulation and to number of grafts. Ten measurements were performed by bioelectrical impedance equipment. RESULTS The comparison of reactance before surgery to the first measurement at the first postoperative day, for the different times of extracorporeal circulation, showed decrease (p = 0.01). Regarding gender, resistance and reactance showed significant differences (p < 0.001). There was also significant difference (p = 0.001) for the number of grafts. CONCLUSION The decrease of resistance and reactance is related not only with surgery procedure, but also with the number of grafts and time of extracorporeal circulation.

Abstract
In this work with ab initio computations, we describe relevant interactions between protein active sites and ligands, using as a test case arthropod hemocyanins. A computational analysis of models corresponding to the oxygenated and deoxygenated forms of the hemocyanin active site is performed using the Density Functional Theory approach. We characterize the electron density distribution of the binding site with and without bound oxygen in relation to the geometry, which stems out of the crystals of three hemocyanin proteins, namely the oxygenated form from the horseshoe crab Limulus polyphemus, and the deoxygenated forms, respectively, from the same source and from another arthropod, the spiny lobster Panulirus interruplus. Comparison of the three available crystals indicate structural differences at the oxygen binding site, which cannot be explained only by the presence and absence of the oxygen ligand, since the geometry of the ligand site of the deoxygenated Panulirus hemocyanin is rather similar to that of the oxygenated Limulus protein. This finding was interpreted in the frame of a mechanism of allosteric regulation for oxygen binding. However, the cooperative mechanism, which is experimentally well documented, is only partially supported by crystallographic data, since no oxygenated crystal of Panulirus hemocyanin is presently available. We address the following question: is the local ligand geometry responsible for the difference of the dicopper distance observed in the two deoxygenated forms of hemocyanin or is it necessary to advocate the allosteric regulation of the active site conformations in order to reconcile the different crystal forms? We find that the difference of the dicopper distance between the two deoxygenated hemocyanins is not due to the small differences of ligand geometry found in the crystals and conclude that it must be therefore stabilized by the whole protein tertiary structure.

Abstract
In a sample of 200 subjects, representative of a population of 1936 civil servants, we tested differences in life style, dietary habits and distribution of risk factors for CHD between smokers and nonsmokers. The two groups (79 smokers) and (121 non-smokers) did not differ significantly by age or sex. The percentage of sedentary subjects, of hypercholesterolaemics and of hypertensives was found to be particularly high among smokers: 67%, 33% and 30% respectively (vs 59%, 27% and 19% in non-smokers). More smokers were obese (11% vs 5%) but mean BMI was the same in smokers/non-smokers but showed a higher fat mass; the association of CHD risk factors indicates only one significant correlation (P < 0.05) between obesity and hypertension. In male smokers, higher values of LDL and triglycerides and lower intake of energy, vitamins C and A are observed and these values are significantly different than those for non-smokers. In women HDL values are higher in non-smokers whereas, in female smokers, the food cholesterol intake is particularly high 271 +/- 295 mg. There are also correlations both for the anthropometric and clinical parameters and for energy and nutrients, indicating that the lifestyle of smokers is less healthy than that of non-smokers. Smokers cat vegetables and fruits less frequently and consume more alcohol than non-smokers, who prefer sweet foods.

Abstract
This study was conducted to determine the prevalence and profile of use of benzodiazepines in the Italian population and risk factors for use. Between November 1992 and February 1993, 62 general practitioners submitted a validated self-administered questionnaire on health status and drug use to a randomised sample of 3100 subjects ( > or = 18 years of age, stratified by sex and age), of whom 2803 responded (response, rate 90.4%). Main outcome measures were point estimate (past-week) of all the drugs taken by each individual, dosage and length of use and source of the prescription. The overall past-week prevalence of use of benzodiazepines was 8.6% (5.0% males and 11.8% females). In the elderly ( > or = 65 years) 18.8% reported current use (9.0% males and 24.7% females). Fifty-six per cent of the persons exposed to a benzodiazepine were chronic users (daily, for more than 6 months), and 70.1% in subjects > or = 65 years. The average daily dose taken was relatively low: 61% of short-term users and 51% of chronic users used less than half a defined daily dose (DDD). Female sex, older age, unemployment and retirement were independently associated with the use of benzodiazepines. Benzodiazepine use in Italy appeared to be relatively high (about 9% of subjects reported current use 57% of whom were chronic users). Women were prescribed a benzodiazepine twice as often as men and one out of four elderly women was on treatment. Although the average dosage used was rather low, the high prevalence and the elevated proportion of chronic users should encourage drug information campaigns and educational interventions to promote a more conservative use of these drugs especially in the elderly.

Abstract
The Italian Group for Epidemiological Research in Dermatology (GISED) collected a series of cutaneous adverse reactions following NSAID and/or antibiotics administered by topical and/or systemic route. Dermatologists from North and Central Italy took part in this survey by filling in 1457 case report forms during a four-month observation time in 1988-89. The main purpose of our epidemiological study aimed at evaluating a post-marketing surveillance program by examining spontaneous reports of cutaneous adverse reactions. This result seems to be noteworthy, considering the difficulties encountered in Italy to develop such a program.

Abstract
We report the results of a multicentric evaluation on effectiveness and safety of isotretinoin in severe acne, recalcitrant to traditional treatments. 208 patients, suffering especially from cystic acne, have been enrolled in a post-marketing clinical trial in 11 Dermatological Italian Departments. The clinical effectiveness of isotretinoin has been very good in 77% of patients, good in 16% and sufficient in 4%. The tolerability of the drug was considered good in 90% of patients. Finally, isotretinoin might be considered as one of the most effective drugs in the therapy of severe forms of acne, resistant to usual treatment, and often affecting patients on the physical and psychological side.

Abstract
The authors report ten cases of multiple meningiomas in a series of 227 intracranial meningiomas from 1977 to 1984. The incidence of multiple meningiomas was 4.4% (according to Cushing and Eisenhardt's [1938] concept of "multiplicity" of such tumours). These results are comparable to those obtained by other authors. All patients were females and all underwent CT scan before operation. Clinical symptoms are presented along with location and size of the tumours. Pathogenetic theories and research prospects are discussed.

Abstract
The AA. have monitored 202 patients affected by several pathological conditions and at different stages of their pregnancies. Among them, 173 were pregnancies without complications. Monitoring was performed on the basis of the following 3 indices: HCS radioimmunological assay, total plasmatic estriol, and vaginal cytology. Results show, as demonstrated in the graphs and the final discussion, that already within the first weeks of gestation the pathological cases under observation presented marked modifications of the indices studied when compared to controls.
