Abstract
OBJECTIVES To evaluate the prevalence and therapeutic relevance of drug resistance among isolates from ART-experienced HIV-1-infected patients over the past two decades in Italy. METHODS Dynamics of resistance to one, two and three or more antiretroviral classes were evaluated from 1999-2018. Virological success (VS) after the latest therapy switch was evaluated according to cumulative class resistance and cumulative genotypic susceptibility score (Stanford HIV_DB algorithm). RESULTS Among 13 663 isolates (from 6739 patients), resistance to at least one drug class decreased sharply from 1999 to 2010 (≤2001, 84.6%; 2010, 43.6%; P < 0.001), then remained relatively constant at ∼40% during 2010-18, with the proportion of resistance to three or more classes also stable (∼5%). After 2008, integrase inhibitor resistance slightly increased from 5.6% to 9.7% in 2018 and contributed to resistance, particularly in isolates with resistance to three or more classes (one class, 8.4%; two classes, 15.3%; three or more classes, 34.7%, P < 0.001). Among 1827 failing patients with an available follow-up, by 1 year after genotype-guided therapy start the probability of VS was 87.6%. Patients with cumulative resistance to three or more classes and receiving a poorly active regimen showed the lowest probability (62.6%) of VS (P < 0.001) compared with all other patients (≥81.8%). By Cox regression analysis, cumulative MDR and receiving poorly active antiretroviral regimens were associated with a lower hazard of VS compared with those without resistance. CONCLUSIONS A dramatic drop of HIV-1 drug resistance at failure has been achieved over the last two decades in Italy; resistance to three or more classes is low but present among currently failing patients. Its management still requires a rational and careful diagnostic and therapeutic approach.

Abstract
PURPOSE Sperm cryopreservation is fundamental in the management of patients undergoing gonadotoxic treatments. Concerns have risen in relation to SARS-CoV-2 and its potential for testicular involvement, since SARS-CoV-2-positive cryopreserved samples may have unknown effects on fertilization and embryo safety. This study therefore aimed to analyze the safety of sperm cryopreservation for cancer patients after the onset of the pandemic in Italy, through assessment of the risk of SARS-CoV-2 exposure and viral RNA testing of semen samples. METHODS We recruited 10 cancer patients (mean age 30.5 ± 9.6 years) referred to our Sperm Bank during the Italian lockdown (from March 11th to May 4th 2020) who had not undergone a nasopharyngeal swab for SARS-CoV-2 testing. Patients were administered a questionnaire on their exposure to COVID-19, and semen samples were taken. Before cryopreservation, SARS-CoV-2 RNA was extracted from a 150 µl aliquot of seminal fluid in toto using QIAamp viral RNA kit (Qiagen) and amplified by a real time RT PCR system (RealStar SARS-CoV2 RT PCR, Altona Diagnostics) targeting the E and S genes. RESULTS The questionnaire and medical interview revealed that all patients were asymptomatic and had had no previous contact with COVID-19 infected patients. All semen samples were negative for SARS-CoV-2 RNA. CONCLUSION This preliminary assessment suggests that a thorough evaluation (especially in the setting of a multidisciplinary team) and molecular confirmation of the absence of SARS-CoV-2 in seminal fluid from asymptomatic cancer patients may assist in ensuring the safety of sperm cryopreservation.

Abstract
Background Data regarding the prevalence of metallo-β-lactamases (MBLs) among Pseudomonas aeruginosa isolates in cystic fibrosis patients are scarce. Furthermore, there is limited knowledge on the effect of MBL production on patient outcomes. Here we describe a fatal respiratory infection due to P. aeruginosa producing VIM-type MBLs in a lung transplant recipient and the results of the subsequent epidemiological investigation. Case presentation P. aeruginosa isolates collected in the index patient and among patients temporally or spatially linked with the index patient were analyzed in terms of antibiotic susceptibility profile and MBL production. Whole-genome sequencing and phylogenetic reconstruction were also performed for all P. aeruginosa isolates producing VIM-type MBLs. A VIM-producing P. aeruginosa strain was identified in a lung biopsy of a lung transplant recipient with cystic fibrosis. The strain was VIM-1-producer and belonged to the ST308. Despite aggressive treatment, the transplant patient succumbed to the pulmonary infection due to the ST308 strain. A VIM-producing P. aeruginosa strain was also collected from the respiratory samples of a different cystic fibrosis patient attending the same cystic fibrosis center. This isolate harbored the blaVIM-2 gene and belonged to the clone ST175. This patient did not experience an adverse outcome. Conclusions This is the first description of a fatal infection due to P. aeruginosa producing VIM-type MBLs in a lung transplant recipient. The circulation of P. aeruginosa isolates harboring MBLs pose a substantial risk to the cystic fibrosis population due to the limited therapeutic options available and their spreading potential.

Abstract
Droplet microfluidics has become a powerful tool in precision medicine, green biotechnology, and cell therapy for single-cell analysis and selection by virtue of its ability to effectively confine cells. However, there remains a fundamental trade-off between droplet volume and sorting throughput, limiting the advantages of droplet microfluidics to small droplets (<10 pl) that are incompatible with long-term maintenance and growth of most cells. We present a sequentially addressable dielectrophoretic array (SADA) sorter to overcome this problem. The SADA sorter uses an on-chip array of electrodes activated and deactivated in a sequence synchronized to the speed and position of a passing target droplet to deliver an accumulated dielectrophoretic force and gently pull it in the direction of sorting in a high-speed flow. We use it to demonstrate large-droplet sorting with ~20-fold higher throughputs than conventional techniques and apply it to long-term single-cell analysis of Saccharomyces cerevisiae based on their growth rate.

Abstract
Background Transmitted drug-resistance (TDR) remains a critical aspect for the management of HIV-1-infected individuals. Thus, studying the dynamics of TDR is crucial to optimize HIV care. Methods In total, 4323 HIV-1 protease/reverse-transcriptase sequences from drug-naive individuals diagnosed in north and central Italy between 2000 and 2014 were analysed. TDR was evaluated over time. Maximum-likelihood and Bayesian phylogenetic trees with bootstrap and Bayesian-probability supports defined transmission clusters. Results Most individuals were males (80.2%) and Italian (72.1%), with a median (IQR) age of 37 (30-45) years. MSM accounted for 42.2% of cases, followed by heterosexuals (36.4%). Non-B subtype infections accounted for 30.8% of the overall population and increased over time (<2005-14: 19.5%-38.5%, P < 0.0001), particularly among Italians (<2005-14: 6.5%-28.8%, P < 0.0001). TDR prevalence was 8.8% and increased over time in non-B subtypes (<2005-14: 2%-7.1%, P = 0.018). Overall, 467 transmission clusters (involving 1207 individuals; 27.9%) were identified. The prevalence of individuals grouping in transmission clusters increased over time in both B (<2005-14: 12.9%-33.5%, P = 0.001) and non-B subtypes (<2005-14: 18.4%-41.9%, P = 0.006). TDR transmission clusters were 13.3% within the overall cluster observed and dramatically increased in recent years (<2005-14: 14.3%-35.5%, P = 0.005). This recent increase was mainly due to non-B subtype-infected individuals, who were also more frequently involved in large transmission clusters than those infected with a B subtype [median number of individuals in transmission clusters: 7 (IQR 6-19) versus 4 (3-4), P = 0.047]. Conclusions The epidemiology of HIV transmission changed greatly over time; the increasing number of transmission clusters (sometimes with drug resistance) shows that detection and proper treatment of the multi-transmitters is a major target for controlling HIV spread.

Abstract
The aim of this study was to compare the quality of the coronal seal, using an in vitro bacterial invasion test, of three different root canal filling systems. Twenty-seven freshly extracted mandibular premolars were selected and divided into three experimental groups (G1, G2 and G3 n=7) and two control groups (Ct+ and Ct- n=3). All teeth in the experimental groups were prepared using NiTi Mtwo rotating instruments and then the endodontic treatments were completed using the three-tested warm guttapercha root filling techniques: Microseal (G1), Thermafil (G2) and System B (G3). All root filling techniques were performed using the same endodontic sealer (Pulp Canal Sealer). Three teeth were instrumented and not filled, serving as positive controls (Ct+) and the last three teeth, with intact crowns and no endodontic treatment, served as negative controls (Ct-). All samples were mounted in a two-chamber apparatus and exposed to Enterococcus faecalis performing a bacterial infiltration test. All samples were observed for a maximum period of 60 days checking for turbidity of the BHI broth on a daily basis recording when contamination occurred. A quantitative evaluation of the bacterial CFU/ml was performed using the URO-QUICK system. On day 32 an overall value was recorded of contamination of 42.85% for group G1, 71.42% for G2 and 42.85% for G3; after 60 days, the final contamination result was 85.71% for group G1, and 100% for both G2 and G3 groups. Considering the number of contaminated samples at the end of the observation period, the three techniques showed no statistically significant differences. The study highlighted the bacterial permeability of gutta-percha/seal barrier, underlining the importance of an effective coronal restoration to ensure a durable seal after root canal treatment.

Abstract
After transplant, patient infection with human herpesvirus 8 (HHV-8) and Kaposi sarcoma-associated herpesvirus (KSHV) is known to cause aggressive tumors and severe nonneoplastic complications. These latter syndromes are driven by HHV-8/KSHV lytic reactivations and related hyperinflammatory host responses typically characterized by high viral loads, elevated levels of cytokines and other inflammation biomarkers, cytopenia, organ failure, high fever, and worsening conditions (with no evidence of B cell neoplasias). These disorders are associated with a high mortality rate, often due to lack of prompt diagnosis, effective therapeutic approaches, and adequate follow-up. These features resemble most of those defining the so-called KSHV-associated inflammatory cytokine syndrome (KICS), which was recently recognized in patients positive for human immunodeficiency virus (HIV). In this report, we describe-for the first time-a case of a KICS-like nonneoplastic recurrent complication occurring after transplant in an HIV-negative patient that was successfully treated by a combination of anti-CD20 monoclonal therapy, antivirals, and modification of the immunosuppressive regimen. In addition to clinical and laboratory findings collected during 3-year follow-up, we report novel experimental data on HHV-8-specific T cell dynamics and circulating microRNA profile, showing correlations with clinical course and other laboratory markers (including viral load, C-reactive protein, and cytokine levels), providing useful information about abnormal cellular and cytokine dynamics underlying HHV-8-associated inflammatory disorders in posttransplant patients.

Abstract
Objectives To evaluate the maintenance of virological suppression (VS) in antiretroviral-treated HIV-1-suppressed patients switching to a tenofovir/emtricitabine/rilpivirine (TDF/FTC/RPV) single-tablet regimen, by considering pre-existent resistance (pRes). Methods pRes was evaluated according to resistance on all previous plasma genotypic resistance tests. Probability and predictors of virological rebound (VR) were evaluated. Results Three hundred and nine patients were analysed; 5.8% of them showed resistance to both NRTIs and NNRTIs, while 12.6% showed resistance to only one of these drug classes. By 72 weeks, the probability of VR was 11.3%. A higher probability of VR was found in the following groups: (i) patients with NRTI + NNRTI pRes compared with those harbouring NRTI or NNRTI pRes and with those without reverse transcriptase inhibitor pRes (39.2% versus 11.5% versus 9.4%, P < 0.0001); (ii) patients with a virus with full/intermediate resistance to both tenofovir/emtricitabine and rilpivirine compared with those having a virus with full/intermediate resistance to tenofovir/emtricitabine or rilpivirine and those having a virus fully susceptible to TDF/FTC/RPV (36.4% versus 17.8% versus 9.7%, P < 0.001); and (iii) patients with pre-therapy viraemia >500 000 copies/mL compared with those with lower viraemia levels (>500 000: 16.0%; 100 000-500 000: 9.3%; <100 000 copies/mL: 4.8%, P = 0.009). pRes and pre-therapy viraemia >500 000 copies/mL were independent predictors of VR by multivariable Cox regression. Conclusions TDF/FTC/RPV as a treatment simplification strategy shows a very high rate of VS maintenance. The presence of pRes to both NRTIs and NNRTIs and a pre-therapy viraemia >500 000 copies/mL are associated with an increased risk of VR, highlighting the need for an accurate selection of patients before simplification.

Abstract
Euglena gracilis (E. gracilis) has recently been attracting attention as a potential renewable source for the production of biofuels, livestock feed, cosmetics, and dietary supplements. Research has focused on strain isolation, productivity improvement, nutrient and resource allocation, and co-product production, key steps that ultimately determine the economic viability and compatibility of the biomass produced. To achieve these characteristics, approaches to select E. gracilis mutants with desirable properties, such as high wax ester content, high growth rate, and high environmental tolerance for biodiesel and biomass production, are needed. Flow-based analysis and sorting can be rapid and highly automated but calls for techniques that can precisely control the position of E. gracilis with varying sizes and shapes in a tightly focused stream in a high-throughput manner. In this work, we use a stepped microchannel consisting of a low-aspect-ratio straight channel and a series of expansion regions along the channel height. We study horizontal and vertical focusing, orientation, rotational, and translational behaviors of E. gracilis as a function of aspect ratio (AR) and channel Reynolds number (Re). By making use of inertial focusing and local secondary flows, E. gracilis with diverse shapes are directed to a single equilibrium position in a single focal stream. As an application of on-chip flow cytometry, we integrate a focusing microchip with a custom laser-two-focus (L2F) optical system and demonstrate the detection of chlorophyll autofluorescence as well as the measurement of the velocity of E. gracilis cells flowing through the microchannel.

Abstract
Thymosin alpha 1 (Tα1) is a powerful modulator of immunity and inflammation. Despite years of studies, there are a few reports evaluating serum Tα1 in health and disease. We studied a cohort of healthy individuals in comparison with patients affected by chronic inflammatory autoimmune diseases. Sera from 120 blood donors (healthy controls, HC), 120 patients with psoriatic arthritis (PsA), 40 with rheumatoid arthritis (RA) and 40 with systemic lupus erythematosus (SLE), attending the Transfusion Medicine or the Rheumatology Clinic at the Policlinico Tor Vergata, Rome, Italy, were tested for Tα1 content by means of a commercial enzyme-linked immunosorbent assay (ELISA) kit. Data were analysed in relation to demographic and clinical characteristics of patients and controls. A gender difference was found in the HC group, where females had lower serum Tα1 levels than males (P < 0·0001). Patients had lower serum Tα1 levels than HC (P < 0·0001), the lowest were observed in PsA group (P < 0·0001 versus all the other groups). Among all patients, those who at the time of blood collection were taking disease-modifying anti-rheumatic drugs (DMARD) plus steroids had significantly higher Tα1 levels than those taking DMARD alone (P = 0·044) or no treatment (P < 0·0001), but not of those taking steroids alone (P = 0·280). However, whichever type of treatment was taken by the patients, serum Tα1 was still significantly lower than in HC and there was no treatment-related difference in PsA group. Further prospective studies are necessary to confirm and deepen these observations. They might improve our understanding on the regulatory role of Tα1 in health and disease and increase our knowledge of the pathogenesis of chronic inflammatory autoimmune diseases.

Abstract
OBJECTIVES We evaluated the virological response in patients starting a regimen based on darunavir/ritonavir (DRV/r), which is currently the most widely used ritonavir-boosted protease inhibitor. METHODS Data from 206 drug-naïve and 327 PI-experienced patients starting DRV/r 600/100 mg twice daily (DRV600) or 800/100 mg once daily (DRV800) were examined. The probabilities of virological success (VS) and virological rebound (VR) were evaluated in survival analyses. Baseline DRV/r resistance and its evolution at failure were also examined. RESULTS DRV600 was preferentially administered in patients with complex requirements (older age, higher viraemia, lower CD4 cell count and DRV/PI resistance) compared with DRV800. By 12 months, the probability of achieving VS was 93.2% and 84.3% in drug-naïve and PI-experienced patients, respectively. The higher the baseline viraemia, the longer was the time required to achieve VS, both in drug-naïve patients [>500 000 HIV-1 RNA copies/mL: median [interquartile range (IQR)] 6.1 (5.1-10.3) months; 100 000-500 000 copies/mL: median (IQR) 4.9 (3.8-6.1) months; <100 000 copies/mL: median (IQR) 3.9 (3.5-4.8) months; P < 0.001] and in PI-experienced patients [≥100 000 copies/mL: median (IQR) 7.2 (5.7-11.6) months; <100 000 copies/mL: median (IQR) 2.8 (2.4-3.3) months; P < 0.001]. In PI-experienced patients, the probability of VR was higher for higher viraemia levels (22.3% for ≥100 000 copies/ml vs. 9.7% for <100 000 copies/mL; P = 0.007). Baseline resistance did not affect the virological response. At failure, a high percentage of patients maintained virus susceptible to all PIs (drug-naïve: 95%; PI-experienced: 80%). Despite being used more often in patients with more complex requirements, DRV600 performed as well as DRV800. CONCLUSIONS In clinical practice, use of DRV/r (with its flexible dosage) results in high rates of virological response. These data support the use of PI/r in patients whose characteristics require potent drugs with a high genetic barrier.

Abstract
Inertial focusing in microfluidic channels has been extensively studied experimentally and theoretically, which has led to various applications including microfluidic separation and enrichment of cells. Inertial lift forces are strongly dependent on the flow velocity profile and the channel cross-sectional shape. However, the channel cross-sections studied have been limited to circles and rectangles. We studied inertial focusing in non-rectangular cross-section channels to manipulate the flow profile and thus the inertial focusing of microparticles. The location and number of focusing positions are analyzed with varying cross-sectional shapes and Reynolds number. We found that the broken symmetry of non-equilateral triangular channels leads to the shifting of focusing positions with varying Reynolds number. Non-rectangular channels have unique mapping of the focusing positions and the corresponding basins of attraction. By connecting channels with different cross-sectional shapes, we were able to manipulate the accessible focusing positions and achieve focusing of microparticles to a single stream with ∼99% purity.

Abstract
OBJECTIVES Integrase drug resistance monitoring deserves attention because of the increasing number of patients being treated with integrase strand-transfer inhibitors. Therefore, we evaluated the integrase genotyping success rate at low-level viraemia (LLV, 51-1000 copies/mL) and resistance in raltegravir-failing patients. METHODS An integrase genotypic resistance test (GRT) was performed on 1734 HIV-1 samples collected during 2006-13. Genotyping success rate was determined according to the following viraemia levels: 51-500, 501-1000, 1001-10 000, 10 001-100 000 and >100 000 copies/mL. The reproducibility of integrase GRT was evaluated in 41 plasma samples processed in duplicate in two reference centres. The relationship between LLV and resistance prevalence was evaluated in a subset of 120 raltegravir-failing patients. RESULTS Overall, the integrase genotyping success rate was 95.7%. For viraemia levels 51-500 and 501-1000 copies/mL, the rate of success was 82.1% and 94.0%, respectively. GRT was reproducible, producing sequences with a high similarity and an equal resistance profile regardless of the sequencing centre or viraemia level. Resistance was detected both at LLV and at viraemia >1000 copies/mL (51-500 copies/mL = 18.2%; 501-1000 = 37.5%; 1001-10 000 = 53.7%; 10 001-100 000 = 30.0%; and >100 000 = 30.8%). At viraemia ≤500 copies/mL, Q148H/K/R and N155H had the same prevalence (9.1%), while the Y143C/H/R was completely absent. At early genotyping (within 3 months of raltegravir treatment), Q148H/K/R and N155H mutations were detected regardless of the viraemia level, while Y143C/H/R was observed only in samples with viraemia >1000 copies/mL. CONCLUSIONS Our findings prove the reliability of HIV-1 integrase genotyping and reinforce the concept that this assay may be useful in the management of failures even at LLV.

Abstract
Limited space for cell division, perhaps similar to the compressed microenvironment of a growing tumor, has been shown to induce phenotypic and karyotypic changes to a cell during mitosis. To expand understanding of this missegregation of chromosomes in aberrant multi-daughter or asymmetric cell divisions, we present a simple technique for subjecting mammalian cells to adjustable levels of confinement which allows subsequent interrogation of intracellular molecular components using high resolution confocal imaging. PDMS micropatterned confinement structures of subcellular height with neighboring taller media reservoir channels were secured on top of confluent cells with a custom compression well-plate system. The system improved ease of use over previous devices since confined cells could be initially grown on glass coverslips in a 12-well plate, and subsequently be imaged by high resolution confocal imaging, or during compression by live cell imaging. Live cell imaging showed a significant increase in abnormal divisions of confined cells across three different cell lines (HeLa, A375, and A549). Immunofluoresecence stains revealed a significant increase in cell diameter and chromosome area of confined cells, but no significant increase in centrosome-centromere distance upon division when compared to unconfined cells. The developed system could open up studies more broadly on confinement effects on mitotic processes, and increase the throughput of such studies.

Abstract
BACKGROUND The unceasing and widespread increase of alcohol consumption represents an important problem for the European Union. For this reason, we wanted to investigate the patterns of alcohol consumption among high-school students of Rieti, a city in central Italy, and of surrounding rural areas. Furthermore, the study intends to investigate students' awareness on alcohol-related health risks and on the consequences of driving in a state of intoxication. METHODS In the investigation 7 schools including senior high schools and technical schools were involved, for a total of 669 students aged between 15 and 19 years. As part of a program of health education, a self-administered anonymous questionnaire was proposed to each student. A descriptive and multivariate analysis was carried out. RESULTS The prevalence of usual drinkers was equal to 12.7 per cent. The logistic regression analysis showed a statistically significant association between usual consumption of alcohol and the attendance of Technical Institutes (OR=3.43; 95% IC: 2.07 - 5.69), and the residence in rural areas (OR=2.19; 95% IC: 1.38 - 3.47). The area of residence in the multivariate analysis loses significance. Only 54.6 % of the students answered the questions regarding the state of driving under the effect of alcohol; of these, 11.0 % declared of having driven at least once under the effect of alcohol, whereas 18.0 % declared that they had been passengers of a driver who was drunk. The answer to the question whether the consumption of alcohol is harmful to health was "no" for 15.7 % of usual drinkers against 2.2 % of the non drinkers or occasional (episodic) drinkers. CONCLUSIONS Our study shows that the drinking habits of high school students of Rieti are worse for those attending technical schools. Usual drinkers show lower consciousness of alcohol-related harm. Our study may provide clues useful for the identification of the target population at high risk for alcohol abuse in order to create targeted prevention programs.

Abstract
Because of its low profile and biologically inert behavior, thin film nitinol (TFN) is ideally suited for use in construction of endovascular devices. We have developed a surface treatment for TFN designed to minimize platelet adhesion by creating a superhydrophilic surface. The hemocompatibility of expanded polytetrafluorethylene (ePTFE), untreated thin film nitinol (UTFN), and a surface treated superhydrophilic thin film nitinol (STFN) was compared using an in vitro circulation model with whole blood under flow conditions simulating a moderate arterial stenosis. Scanning electron microscopy analysis showed increased thrombus on ePTFE as compared to UTFN or STFN. Total blood product deposition was 6.3 ± 0.8 mg/cm(2) for ePTFE, 4.5 ± 2.3 mg/cm(2) for UTFN, and 2.9 ± 0.4 mg/cm(2) for STFN (n = 12, p < 0.01). ELISA assay for fibrin showed 326 ± 42 μg/cm(2) for ePTFE, 45.6 ± 7.4 μg/cm(2) for UTFN, and 194 ± 25 μg/cm(2) for STFN (n = 12, p < 0.01). Platelet deposition measured by fluorescent intensity was 79,000 20,000 AU/mm(2) for ePTFE, 810 ± 190 AU/mm(2) for UTFN, and 1600 ± 25 AU/mm(2) for STFN (n = 10, p < 0.01). Mass spectrometry demonstrated a larger number of proteins on ePTFE as compared to either thin film. UTFN and STFN appear to attract significantly less thrombus than ePTFE. Given TFN's low profile and our previously demonstrated ability to place TFN covered stents in vivo, it is an excellent candidate for use in next-generation endovascular stents grafts.

Abstract
A typical feature of ageing is a chronic, low-grade inflammation characterized by a general increase in the production of pro-inflammatory cytokines and inflammatory markers ("inflamm-ageing"). This status may slowly damage one or several organs, especially when unfavorable genetic polymorphisms and epigenetic alterations are concomitant, leading to an increased risk of frailty together with the onset of age-related chronic diseases. The contribution of different tissues (adipose tissue, muscle), organs (brain, liver), immune system and ecosystems (gut microbiota) to age-related inflammation ("inflamm-ageing") will be discussed in this review in the context of its onset/progression leading to site-restricted and systemic effects. Moreover, some of the possible strategies and therapies to counteract the different sources of molecular mediators which lead to the age-related inflammatory phenotype will be presented.

Abstract
In order to evaluate the risk connected with hand-arm vibration exposure and associated disorders of the peripheral nervous system a study was made to assess the relationship between nervous symptoms and laboratory data to determine the kind of disorder. 40 male subjects with hand-arm vibration exposure for more than 5 years and nervous symptoms of the hands for more than 1 year and 2 control groups of non-symptomatic non-exposed subjects were considered. An electroneurophysiological study of the exposed subjects revealed 18 nerve conduction speed changes (12 median nerve, 4 ulnar nerve, 2 median and ulnar nerve), most of which were sensitivity-motor changes; only 9 Carpal Tunnel Syndromes were diagnosed. Some statistically significant differences between exposed subjects with negative results of the electroneurophysiological study and non-exposed subjects were observed. Prolonged vibration exposure seems to induce a hand-arm nerve suffering, initially with a progressive nerve conduction speed change and non-specific symptoms, but subsequently a peripheral nervous system disorder associated or not to a Carpal Tunnel Syndrome may occur.

Abstract
Heart transplantation on the first day of life, and graft harvesting from anencephalic donors, have been very rare events in the history of transplantation. At Bambino Gesù Hospital (Rome), heart transplantation was performed on a newborn 9 h after birth, using a graft harvested from an anencephalic donor. This graft achieved a good cardiocirculatory function, but the recipient died of necrotizing enterocolitis (NEC) on post-operative day (POD) 10. Despite failure, this case and other reports support the concept that hearts from anencephalic donors can work normally, and indicate that heart transplantation on the first day of life may have a favorable outcome if postoperative maintenance of multi-organ balance and function is successful.

The knowledge of echocardiographic pitfalls, which may impair the correct indication for surgery of aortic coarctation, is of great importance to pediatric cardiologists. We believe that only the suspicion of coronary artery anomalies is a clear indication to perform a cardiac catherization.

Abstract
OBJECTIVE Two-dimensional, Doppler and color-flow echocardiography is accepted as a safe diagnostic tool to guide the surgical treatment of certain congenital heart defects. Its role for surgical indication in patients with complete atrioventricular canal (cAVC) is described in this paper. METHODS Between July 1989 and January 1995, 80 patients with cAVC underwent primary repair in our Institution. In 73 surgery was guided only by echocardiography (Group I), while in the remaining 7 patients (Group II) cardiac catheterization was performed because of unclear diagnosis and/or suspected associated malformations. RESULTS Echocardiography showed an overall sensitivity of 100% and specificity of 93% in detecting associated malformations. DISCUSSION Based on these data and on the knowledge of the natural history of pulmonary vascular changes in patients with cAVC we think that echocardiography might be adequate for selection of infants with uncomplicated forms of cAVC for primary repair.

Abstract
The case of a 34 month-old infant with cardiac murmur and echocardiographic signs of coronary artery fistula is presented. Cardiac catheterization was performed, revealing a right coronary artery-to-right ventricle fistula, and a significant left-to-right shunt. At 4.0 years of age she underwent a repeated catheterization, showing complete spontaneous closure of the fistula. Review of the literature shows that fistulas draining into the right ventricle have some chance to close spontaneously. Accordingly, clinical approach should therefore be considered.

Abstract
Although 2-dimensional, Doppler, color flow echocardiography is accepted as a safe diagnostic method to guide the surgical treatment of certain heart defects, cardiac catheterization remains mandatory for patients with tetralogy of Fallot. Based on the excellent diagnostic correlation between echocardiography and angiocardiography, a policy of echo-guided primary repair of uncomplicated, selected cases of tetralogy of Fallot was introduced at Ospedale Bambino Gesù. In the last 5 years, of 139 patients who had surgery for tetralogy of Fallot, 105 underwent primary repair. In 56 patients (53.3%), surgery was guided only by echocardiography (group I). In the remaining 49 patients (46.7%) (group II), unclear imaging of cardiovascular anatomy (n = 23), or echo-suspected associated malformations (n = 26) prompted cardiac catheterization. The 2 groups did not differ in age and weight at surgery. Intraoperative examination did not show diagnostic errors in patients of group I; cardiac catheterization and surgery confirmed the suspected associated anomalies in 16 of 26 patients of group II (38.4% false-positive). Echocardiography showed an overall sensitivity of 100% and specificity of 85% for detection of associated malformations. In conclusion, echocardiography proved to be adequate for selection of patients with uncomplicated forms of tetralogy of Fallot for primary repair.

Abstract
We studied 60 patients who had survived the Mustard procedure for transposition of the great arteries, performed between the ages of 2 days and 24 months (mean 4.51 +/- 3.79). All patients were given a postoperative 24-hour dynamic electrocardiogram at 15 days, 1 year and 3 years and then every 2 years. Those who were found to have sinus node dysfunction during follow-up, were given a dynamic electrocardiogram every 3-6 months. The average follow-up period was 38.7 +/- 19.8 months, median 36. Sinus node dysfunction was detected during follow-up in 20 patients (33.3% of the total), 8 of whom had had a pacemaker inserted. Risk factors for late development of sinus node dysfunction were found to include prolonged cross-clamping of the aorta during surgery (P = 0.003), especially over 50 minutes (relative risk 3.5:1), and the presence of even transient sinus node dysfunction after surgery (P = 0.006). These observations suggest, first, that sinus node dysfunction may develop after the Mustard operation as a combined effect of extensive atrial surgery and a long period of myocardial ischemia and, second, that the presence of the disease immediately after the operation sometimes indicates that it will recur or persist during follow-up.

Abstract
Junctional ectopic tachycardia after surgical repair of congenital heart defects is associated with high mortality. Usually, it is transitory and resolves spontaneously, but a long period with very fast heart rate and without atrio-ventricular synchrony contraction may cause low cardiac output. Treatment with common anti-arrhythmic drugs is often uneffective both in restoring sinus rhythm and in reducing heart rate. Since hypothermia is known to decrease cardiac automaticity, two infants, aged 4 and 10 months, with junctional ectopic tachycardia and low cardiac output after surgical repair of the atrio-ventricular septal defect were treated with hypothermia after unsuccessful pharmacological attempts to control the arrhythmia. Generalized hypothermia was induced with cooling-blankets and ice packs. Rectal temperature initially dropped to 30 degrees and was subsequently maintained at between 33.8 and 34.2 degrees with the heart rate between 130 and 140 m beats per minute. Trans-oesophageal atrial pacing at a higher rate allowed for sequential atrio-ventricular contraction. Signs of low cardiac output were quickly resolved. One patient was warmed-up after 12 hours of hypothermia and remained in sinus rhythm. In the other patient, the arrhythmia recurred after rewarming and a further 30-hour period of hypothermia was required. Sinus rhythm was maintained thereafter. Both patients are in stable sinus rhythm 20 and 22 months after surgery. Our experience supports the use of hypothermia as a means to control post-operative junctional ectopic tachycardia resistant conventional anti-arrhythmic drugs.

Abstract
Eight-six children (aged 20 days to 14 years, 20 under age 1 year) underwent 94 percutaneous balloon valvuloplasty for pulmonary valve stenosis. The patients were divided into three groups: typical pulmonary valve stenosis (71), pulmonary valve dysplasia (9), and residual stenosis after surgical valvotomy for pulmonary atresia with intact ventricular septum (PAIS) (6). Each of the three groups was divided into two subgroups. In the early cases, balloon catheters with diameter 10-20% exceeding pulmonary valve annulus were used and the drop of the gradient was 39.5%. In the later cases, balloon diameters 30-40% greater than the valve anulus or double balloons were used and a drop of 66.7% in the RV-PA pressure gradient was achieved. The dilation in patients with dysplastic valve and residual stenosis after surgical valvotomy for PAIS was less effective. Doppler echocardiography was the technique used to evaluate residual gradient. Six months to 4 years follow-up demonstrated a persistent decrease of the valve gradient.

Abstract
Double inlet left ventricle with concordant ventriculo-arterial connection, first described by Holmes, is an unusual cardiac malformation which includes a right-sided rudimentary right ventricle and, frequently, subpulmonary stenosis. We have now encountered six patients, aged 1 month to 13 years, with this basic combination. In 5 cases, cross-sectional echocardiography, using parasternal, apical and subcostal views was diagnostic. Subpulmonary stenosis was seen in two of them. The sixth case shown to have atresia of the left atrioventricular valve, a concordant ventriculo-arterial connection, a left-sided rudimentary right ventricle, mild subpulmonary stenosis and a right-sided aorta. The combination of the left atrioventricular valve, left-sided rudimentary right ventricle and a concordant ventriculo-arterial connection has not, to our knowledge, been previously reported. Cross-sectional echocardiography always provided the correct morphologic diagnosis.

Abstract
We describe the use of percutaneous balloon angioplasty of a stenotic truncal valve in a newborn with a common arterial trunk. A 12 mm balloon catheter was chosen, this representing 80% of the diameter of the ventriculo-truncal junction. The peak systolic gradient dropped from 45 to 15 mm Hg. The procedure can avoid, or certainly delay, surgical treatment of the stenotic truncal valve.

Abstract
The Fontan principle, defined as a procedure in which the right ventricle is bypassed in order to convey desaturated venous blood from the right atrium to the lungs, is presently applied for a wide variety of congenital heart malformations including those in which there is no suitable ventricular pumping chamber. Recently, the procedure has also been advocated for complex malformations that require atrial septation or intra-atrial rerouting. The present report evaluates our experience in four patients with such complex malformations. Three had a complete form of atrioventricular septal defect with double-outlet right ventricle and one patient had left atrioventricular valve atresia. The common atrium was morphologically right in two patients and morphologically left in one. In each of these instances anomalous pulmonary venous connections were present, together with abnormal systemic venous connections. The results were unsatisfactory. Three of the four patients died. The only survivor had no pulmonary or systemic venous abnormalities. Severe impairment of pulmonary blood flow was one of the most important postoperative complications. The findings suggest that the complexities of rerouting the blood within the atria play an important role. The excess proportion of prosthetic material to atrial myocardium may result in excessive loss of contractile atrial myocardium and, probably equally significant, in a complex intra-atrial geometry of pathways that may cause a critical pressure gradient. The results clearly show that with an expanding horizon of the application of the Fontan principle, new pitfalls may arise which presently appear to be the prevailing factors limiting its success.

Abstract
Five patients were operated on for ventricular septal rupture following myocardial infarction. The mean time interval between occurrence of infarction and surgery was 37 days (from 4 to 54 days). At EKG, the infarction site was anteroseptal in two cases and postero-inferior in three. Progressive deterioration of cardiac function leading to cardiogenic shock was noticed in four patients. Four patients had cardiac catheterization before surgery: the mean pulmonary to systemic flow ratio was 2.5:1 (from 3.8:1 to 1.8:1); in each case L.V.E.D.P., pulmonary wedge and pulmonary arterial pressures were elevated. Left ventricular angiograms and selective coronariograms were obtained in three patients, demonstrating the presence of left ventricular aneurysm in all three. In two patients, repair was performed through right ventriculotomy; in patients with left ventricular aneurysm, a left ventriculotomy and aneurysm resection were performed. This technique seems to permit much clearer view of the rupture site. In all patients the V.S.D. was closed by a dacron patch, reinforced with teflon pledgets. Two of the five patients died in the early postoperative period. Both had been operated within the first week from the onset of the ventricular septal rupture, because of cardiogenic shock, refractory to medical therapy. The three survivors showed remarkable improvement after surgery and they are in functional class II at a mean follow up period of 20 months. Emphasis is put on factors influencing surgical treatments and prognosis of these patients.

Abstract
Thirty-two patients were submitted to an emergency surgical procedure for left ventricular asynergy, following myocardial infarction. Indications and results are analyzed. All patients were operated upon with the aid of cardiopulmonary by-pass; an aneurysmectomy was performed in twenty-nine patients, a plication technique in three. These procedures were combined with mitral and/or aortic replacement in five patients, closure of ventricular septal defect in five, aorto-coronary saphenous vein by-pass in five. Early over all post-operative mortality was 75%: 80% in patients operated within three months from myocardial infarction, 67% in patients operated after three months from myocardial infarction.
