Abstract
Constitutional complex chromosomal rearrangements (CCRs) are considered rare cytogenetic events. Most apparently balanced CCRs are de novo and are usually found in patients with abnormal phenotypes. High-resolution techniques are unveiling genomic imbalances in a great percentage of these cases. In this paper, we report a patient with growth and developmental delay, dysmorphic features, nervous system anomalies (pachygyria, hypoplasia of the corpus callosum and cerebellum), a marked reduction in the ossification of the cranial vault, skull base sclerosis, and cardiopathy who presents a CCR with 9 breakpoints involving 4 chromosomes (3, 6, 8 and 14) and a 0.6-Mb deletion in 14q24.1. Although the only genomic imbalance revealed by the array technique was a deletion, the clinical phenotype of the patient most likely cannot be attributed exclusively to haploinsufficiency. Other events must also be considered, including the disruption of critical genes and position effects. A combination of several different investigative approaches (G-banding, FISH with different probes and SNP array techniques) was required to describe this CCR in full, suggesting that CCRs may be more frequent than initially thought. Additionally, we propose that a chain chromosome breakage mechanism may have occurred as a single rearrangement event resulting in this CCR. This study demonstrates the importance of applying different cytogenetic and molecular techniques to detect subtle rearrangements and to delineate the rearrangements at a more accurate level, providing a better understanding of the mechanisms involved in CCR formation and a better correlation with phenotype.

Abstract
This paper presents a novel bat-like unmanned aerial vehicle inspired by the morphing-wing mechanism of bats. The goal of this paper is twofold. Firstly, a modelling framework is introduced for analysing how the robot should manoeuvre by means of changing wing morphology. This allows the definition of requirements for achieving forward and turning flight according to the kinematics of the wing modulation. Secondly, an attitude controller named backstepping+DAF is proposed. Motivated by biological evidence about the influence of wing inertia on the production of body accelerations, the attitude control law incorporates wing inertia information to produce desired roll (ϕ) and pitch (θ) acceleration commands (desired angular acceleration function (DAF)). This novel control approach is aimed at incrementing net body forces (F(net)) that generate propulsion. Simulations and wind-tunnel experimental results have shown an increase of about 23% in net body force production during the wingbeat cycle when the wings are modulated using the DAF as a part of the backstepping control law. Results also confirm accurate attitude tracking in spite of high external disturbances generated by aerodynamic loads at airspeeds up to 5 ms⁻¹.

Abstract
Background Gross cystic disease fluid protein-15(GCDFP-15)/prolactin-inducible protein (PIP) is a secretory acinar glycoprotein of 14 KDa which we have recently described as significantly lower in salivary samples of patients with primary Sjögren’s syndrome (pSS) in comparison to healthy volunteers by proteomic analysis. Aims of the study (1) to validate our previous data on the decrease of GCDFP-15/PIP protein in a larger number of subjects with pSS (2) to integrate the proteomic results with complementary immunoassays in order better clarify the pathophysiological relevance of GCDFP-15/PIP in pSS exocrinopathy (3) to assess both the glandular expression of the GCDFP-15/PIP and the levels of glandular GCDFP-15/PIP mRNA in the patients’ minor salivary gland (MSG) biopsies in order to verify whether the observed reduction of GCDFP-15/PIP in saliva may be related to a decrease in the protein production. Patients and methods A total of 123 salivary samples from patients affected by pSS, no-SS sicca syndrome and sex- age-matched healthy volunteers were analyzed by different proteomic techniques (SELDI-TOF-MS, 2DE, MALDI-TOF-MS). The expression of GCDFP-15/PIP was then validated by western blot analysis. Real Time PCR and immunohistochemistry for GCDFP-15/PIP in the minor salivary glands (MSG) biopsies were then carried out. Results By using complementary proteomic analysis we found that a putative peak of 16547 m/z was among the best independent biomarkers for pSS able to discriminate between patients and healthy controls with a sensitivity of 96 % and a specificity of 70%, with a global cross validated error of 29%. We identified the peak as the GCDFP-15/PIP protein and verified that the intensity of GCDFP-15/PIP was significantly lower in pSS patients when compared to both no-SS sicca subjects and healthy controls (p<0.0001). GCDFP-15/PIP expression also correlated with both the salivary flow rate (r=0.312, p=0.023) and MSG biopsies focus score (r=−0.377, p=0.04). Finally, immunohistochemistry confirmed that GCDFP-15/PIP staining was faint in mucus acini and Real Time PCR showed that GCDFP-15/PIP mRNA was significantly lower in pSS patients when compared to both no-SS sicca subjects and healthy controls (p=0.023) thus supporting the hypothesis that the observed reduction of GCDFP-15/PIP in pSS saliva may be related to a decrease in the protein production. Conclusion In this study by different complementary-omic techniques we confirmed the potential role of GCDFP-15/PIP as a novel biomarker for pSS. This finding might also be functionally important as GCDFP-15/PIP has previously been shown to bind to Aquaporin 5 (AQP5), a salivary gland water channel, critical to saliva formation that is known to be downregulated in pSS. It is likely that exploring the GCDFP-15/PIP/AQP5 axis will help better understand the mechanism of salivary gland dysfunction in pSS.

Abstract
Kidney transplantation is currently the treatment of choice in most patients with end-stage chronic renal failure owing to the excellent results in terms of both graft and patient survival. However, surgical complications are still very frequent. Although urological (stricture, urinary fistulas, vesico-ureteral reflux) and lymphatic complications (lymphocoele) have a high incidence, they only rarely lead to graft loss. By contrast, vascular complications (stenosis, arterial and venous thrombosis, arterio-venous fistulas, pseudoaneurysms) are relatively rare, but potentially serious and may affect graft survival. Finally, medical complications such as acute tubular necrosis (ATN), rejection and de novo neoplasms may also arise in kidney transplantation. The purpose of this pictorial review is to illustrate the increasingly significant contribution of magnetic resonance angiography (MRA) in the management of complications of kidney transplantation, and emphasise how this method should now be considered a mandatory step in the diagnostic workup of selected cases. Moreover, the application and role in this setting of new magnetic resonance imaging (MRI) techniques, such as diffusion-weighted and blood oxygen level-dependent (BOLD) MRI, are also discussed.

Abstract
BACKGROUND AND AIM Gastro-oesophageal reflux disease is a common medical problem that places a significant financial burden on outpatient pharmaceutical expenditure. A substantial proportion of this expenditure can be attributed to the use of proton pump inhibitors (PPIs). The aim of this analysis was to evaluate the cost-effectiveness of PPIs currently licensed in Italy in the acute treatment of reflux oesophagitis. METHODS A decision analysis model that simulated the sequential management of reflux oesophagitis over the course of 8 weeks was constructed. Healing rates were derived from a published meta-analysis of PPIs for reflux oesophagitis. Costs of PPIs were based on retail prices in Italy, endoscopies and specialist (outpatient) visits were costed on the basis of public tariffs, and opportunity costs were calculated for general practitioner visits. The clinical effectiveness of a PPI was measured in terms of the proportion of patients healed at 8 weeks. An incremental cost-effectiveness analysis was performed, using omeprazole, the recognised 'gold standard' PPI in Italy, as the common comparator. The perspective of the analysis was the Italian National Health System (NHS). A sensitivity analysis was conducted in which the key parameters in the model were varied according to a Monte Carlo simulation of 1000 patients. RESULTS Esomeprazole 40 mg/day was a dominant treatment option compared with omeprazole 20 mg/day (88.8% patients healed vs 82.2%, respectively; total treatment cost euro164.85 vs euro169.56, respectively (year of costing, 2002). Furthermore, on the basis of the 95% CIs generated by the Monte Carlo simulation, esomeprazole 40 mg/day appears to be more cost-effective than both lansoprazole 30 mg/day and pantoprazole 40 mg/day. CONCLUSIONS Esomeprazole 40 mg/day can be considered a cost-effective treatment option for the acute treatment of reflux oesophagitis in Italy.

Abstract
The mechanisms responsible for normal tissue late effects following radiotherapy are largely unknown and currently no method for predicting such risks is available. Abnormal levels of cytokine production induced by radiation has been suggested as a contributing factor by multiple investigators. The purpose of the present study was to evaluate plasma levels of transforming growth factor-beta 1 (TGF-beta 1), basic fibroblast growth factor (bFGF), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1 beta (IL-1 beta) in patients with prostate cancer scheduled for radiotherapy (protons, photons, or combination of both). It has been recently shown that ionizing radiation can increase expression of these cytokines and there are indications that they may be associated with morbidity. Blood samples were obtained from 20 subjects (age 51-80) before, during the first week, and immediately after the end of therapy; 3 healthy volunteers served as controls. Significant positive correlations (p<0.05) were obtained between bFGF, IL-1 beta, and TNF-alpha and the integral dose of radiation during the first week of treatment. Correlations approaching significance (p<0.1) were obtained with bFGF and acute treatment-related morbidity. A higher integral dose (due to larger irradiated volumes) was delivered with conventional photon compared to proton irradiation. No significance was obtained with any of the cytokines and pretreatment prostate specific antigen (PSA) levels, patient age, grade or stage of disease, or the integral dose by the end of radiation treatment. These results show that large changes occur in the plasma levels of certain cytokines early after initiation of radiotherapy and that treatment of larger volumes is more likely to induce these changes. Our data support further investigation of the role of cytokines during radiotherapy.

Abstract
This paper presents the design of a bat-like micro aerial vehicle with actuated morphing wings. NiTi shape memory alloys (SMAs) acting as artificial biceps and triceps muscles are used for mimicking the morphing wing mechanism of the bat flight apparatus. Our objective is twofold. Firstly, we have implemented a control architecture that allows an accurate and fast SMA actuation. This control makes use of the electrical resistance measurements of SMAs to adjust morphing wing motions. Secondly, the feasibility of using SMA actuation technology is evaluated for the application at hand. To this purpose, experiments are conducted to analyze the control performance in terms of nominal and overloaded operation modes of the SMAs. This analysis includes: (i) inertial forces regarding the stretchable wing membrane and aerodynamic loads, and (ii) uncertainties due to impact of airflow conditions over the resistance-motion relationship of SMAs. With the proposed control, morphing actuation speed can be increased up to 2.5 Hz, being sufficient to generate lift forces at a cruising speed of 5 m s(-1).

Abstract
OBJECTIVE The aim of this study was to design, deliver and evaluate an e-learning teaching programme for post-graduate radiodiagnostics training that would involve various post-graduate schools throughout Italy. MATERIALS AND METHODS All of the Directors of Italian post-graduate schools of radiodiagnostics were sent an e-mail on 27 September 2010 informing them of our willingness to set up an e-learning project for the academic year 2010-2011 in the form of single-subject teaching seminars. The proposed subjects were the semeiotics of the various organs and apparatuses in the context of "Urgent/Emergency Pathology". After having received registrations, a calendar of lessons was planned to be held between 10 November 2010 and 12 October 2011. The validity of the project was tested by means of a multiple-choice questionnaire covering the technical and didactic quality of the entire project, to be completed by the students. RESULTS Fifty-one percent of the universities in Italy participated in the project: Trieste, Udine, Verona, Milan-Bicocca, Novara, Varese, Genoa, Sassari, Rome Campus, the Catholic University of Rome, Chieti, Foggia, Catania, Modena, Florence, Palermo, Bologna, Pavia, Parma and Ferrara. The lessons were attended by a total of 10,261 post-graduate medical students, for an average of 513.1 students per lesson. Seventy percent of the students judged the didactic content "excellent", 25% "good", and 5% "satisfactory"; none said it was unsatisfactory. In terms of visual quality (particularly the details of the radiological images proposed in the form of slides and/or video clips), 73% judged it "excellent", 20% "good", 6% "satisfactory", and 1% "poor". The audio quality was judged "excellent" by 71%, "good" by 22%, "satisfactory" by 6% and "poor" by 1%. In relation to judgement of audio and video quality, it has to be underlined that this was greatly affected by the hardware/software configuration and the band speed and technology of the Internet connection. CONCLUSIONS Technological evolution is overcoming all barriers, and technology is also having a positive impact on the approach to teaching. Our multicentre teaching experience merits the following considerations: the quality of the teaching product was certified by the students' judgements of its didactic content and the quality of reception; the economic cost of the teaching had a minimal impact on the post-graduate schools (€ 18 per lesson). In terms of breaking down national barriers, it is to be hoped that the coordination and integration of diagnostic imaging e-learning projects, with the participation of post-graduate schools in different European countries, can be developed not only in a spirit of "cultural sharing" and the exchange of teaching experiences.

Abstract
The study analyzes the trend of asbestos-related diseases and mortality in workers of a company in the province of Cremona which manufactured asbestos products. It is confirmed that the exposure to a high concentration of asbestos fibers (estimated to more than 20 fibers/cc) strictly correlates with the onset of pathologies from asbestos. In the studied population were found 19 cases of neoplastic diseases (12 mesotheliomas and 7 bronchopulmonary carcinomas). This figure, compared to the company working population, which over the years has been an average of 80 units, while not enabling to calculate an incidence rate due to the lack of reliable data on population, is indicative of a very significant cause-effect relationship since these are neoplastic diseases that can still arise. So it is necessary to continue the health monitoring of formerly exposed workers and appropriate to try to extend it to all workers of the asbestos compartment.

Abstract
Vascular complications remain a major cause of graft loss after pancreatic transplantation. They include vascular thrombosis, pseudoaneurysm, and arteriovenous fistula (AVF). We report a case of an AVF that appeared 3 months after a simultaneous pancreas-kidney transplantation (SPKT). Doppler ultrasonography followed by magnetic resonance angiography and later angiography provided a definitive diagnosis of a mesenteric AVF. An endovascular approach is becoming the treatment of choice owing to the high risk of graft loss associated with open surgical correction. Microcoils alone, or in conjunction with detachable balloons, are frequently used; still, a new generation of vascular plugs seem to offer a therapeutic option for AVF closure, because it is a "1 shot" procedure that avoids the risk of accidental coil migration. A new-generation Amplatzer Vascular Plug 4 was deployed over the distal arterial branch of the superior mesenteric artery stump, leading to complete exclusion of the AVF and restoring normal vascular flow.

Abstract
It has been hypothesized that lactic acid bacteria (LAB) could be used as adjuvant for specific immunotherapy (SIT), as various studies conducted on humans and animals converge to define LAB as anti-Th2 modulators and Treg inducers. In the present study we evaluated the effects of LAB, in particular Lactobacillus paracasei Lp6 (Lp6), in a mouse model of ragweed (RW) allergy. Groups of Balb/c mice, experimentally sensitized towards ragweed, were treated by viable Lp6 or by RWallergoid with or without co-administration of Lp6. A control group was sham-sensitized with PBS and sham-treated with water and a group was sensitized with RW and treated with water. Serum IgE, RW-induced release of IFN-gamma, IL-4 and IL-10 from splenocytes and the frequency of CD4CD25 regulatory T cells (Tregs) expressing Foxp3 or IL-10 were evaluated in various groups. RW-allergoid treatment induced a reduction of serum IgE, with a decrease in RW-induced release of IL-4, and an increase in IL-10 and IFN-gamma, along with a significant change in the frequency of Tregs, both CD25+ and -. The joint RWallergoid+ Lp6 treatment induced the highest degree of suppression of allergen-driven IL-4, the greatest reduction of IL-4/IFN-gamma and IL-4/IL-10 ratios and the most significant increase of Foxp3 and IL-10 expressing Tregs. The study shows that Lp6 strengthens the immune modulation induced by allergoid-SIT in RW-sensitized mice, essentially characterized by a differential induction of Tregs associated to a reduction of IL-4; data converge to define a role of SIT adjuvant for Lp6.

Abstract
In this paper, we describe our research on bio-inspired locomotion systems using deformable structures and smart materials, concretely shape memory alloys (SMAs). These types of materials allow us to explore the possibility of building motor-less and gear-less robots. A swimming underwater fish-like robot has been developed whose movements are generated using SMAs. These actuators are suitable for bending the continuous backbone of the fish, which in turn causes a change in the curvature of the body. This type of structural arrangement is inspired by fish red muscles, which are mainly recruited during steady swimming for the bending of a flexible but nearly incompressible structure such as the fishbone. This paper reviews the design process of these bio-inspired structures, from the motivations and physiological inspiration to the mechatronics design, control and simulations, leading to actual experimental trials and results. The focus of this work is to present the mechanisms by which standard swimming patterns can be reproduced with the proposed design. Moreover, the performance of the SMA-based actuators' control in terms of actuation speed and position accuracy is also addressed.

Abstract
The widespread use of scrotal ultrasonography (US) has led to increased detection of testicular and extratesticular pathologies. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin. US may suggest a specific diagnosis for a wide variety of intrascrotal cystic and fluid lesions and appropriately guide therapeutic options. US should be used as an adjunctive diagnostic modality after clinical evaluation of a scrotal lesion associated or not with the presence of a lump.

Abstract
BACKGROUND AND OBJECTIVES Calprotectin is a protein especially expressed in neutrophil cytosol. In the last few years, Fecal calprotectin (FC) turned out to be a direct marker of gastrointestinal inflammation. Because of the simplicity of the method, it has been studied in several gastroenterologic diseases but no data are available about its concentration in children with small intestinal bacterial overgrowth (SIBO), a complex and not well known condition defined by an excessive germs proliferation, especially anaerobic, in the small bowel, and characterized by dyspeptic and malabsorption symptoms. The aim of this study was to evaluate FC values in children with SIBO, comparing to healthy subjects, in order to clarify if an inflammatory process coexists with SIBO. MATERIALS AND METHODS We enrolled fifty-eight children affected by SIBO, as diagnosed by Lactulose Breath Test (LBT). They were assessed for FC values on stool samples. We compared them with a control population of 60 healthy children. RESULTS In SIBO patients, a median value of 36.0 mg/kg and a mean value +/- SD of 43.0 +/- 31.6 mg/kg were calculated, while in healthy controls the median value was 29.5 mg/kg and the mean value +/- SD was 35.7 +/- 20.7 mg/kg, showing no statistically significant differences between the two groups (p = 0.07). CONCLUSIONS FC values are negative in children affected by SIBO, not differing from those obtained in healthy children, suggesting that no subclinical intestinal inflammation involving neutrophils occurs in patients with higher proliferation of bacteria in the small bowel. The presence of high FC levels in children affected by SIBO might not be caused by bacterial overgrowth itself and, in this case, another cause should be investigated.

Abstract
BACKGROUND High-dose chemotherapy followed by reinfusion of autologous stem cells harvested from peripheral blood has been increasingly applied for a variety of disorders. The critical importance of cell dose in the clinical outcome, after transplant, has motivated the need to develop techniques aimed at reducing cell losses and increasing reproducibility. OBJECTIVES The aim of this study is to evaluate the efficacy of the Sepax S-100 device to process thawed HPC-A products in comparison with manual procedure. METHODS/MATERIALS We have analysed viability, total nucleated cells (TNC), haematopoietic progenitors and CD34+ cells recovery. RESULTS The TNC and CD34+ cells recovery in the automatic procedure was of 91.9% (73-100; SD ± 12.60) and 86.7% (69-100; SD ± 10.21), respectively. Instead the recovery of TNC and CD34+ cells using the manual method was of 84.7% (47-100; SD ± 22.9) and 80.29% (23-100; SD ± 25.96). The results, obtained from the assessment of viability of CD34+ both 7-AAD)+ and AnnV+ showed a high percentage of necrosis and apoptosis in this cell subset by using the manual procedure in respect to the Sepax automated system. CONCLUSION Overall, our data suggest that the automated washing procedure is safe and suitable for processing of thawed HPC-A products and can be daily used in clinical routine.

Abstract
The authors describe the case of a child with craniofrontonasal syndrome (CFNS) (MIM 304110), the diagnostic process performed, the identification of the main clinical features in the proband (hypertelorism, facial asimmetry, bifid nasal tip, corpus callosum hypoplasia, broad thumb, curly and wiry hair), and the comparison with known data in literature. They also describe the detection, through gene sequencing of EFNB1, of responsible mutation and its correlation with the phenotypic variants. They explain the etiophatogenetic basis of the "unusual" inheritance pattern of CFNS: X-linked disease that occurs with greater severity in heterozygous females than hemizygous males. Finally, attention is placed on the need for careful genetic counseling for patients with CFNS, with special care in familial anamnesis taking. In the studied case, the presence of abnormalities of thumbs in the proband's mother and in two of her cousins, orientates principally toward a mutation of maternal origin or to a suspected somatic and germline mosaicism by creating a recurrence risk greater than general population. Because patients with CFNS reported in the literature are few, the AA consider that the observed case may help to improve understanding of the mechanisms of gene expression responsible for the syndrome, of its peculiar phenotypic manifestations and of its frequency in the population with known and easy to assign phenotypes, and possible mosaicisms that are difficult to detect.

Abstract
The ErbB receptors, such as ErbB-1 and ErbB-2, have been intensely pursued as targets for cancer therapeutics. Although initially efficacious in a subset of patients, drugs targeting these receptors led invariably to resistance, which is often associated with reactivation of the ErbB-3-PI3K-Akt signaling. This may be overcome by an ErbB-3 ligand that abrogates receptor-mediated signaling. Toward this end, we have generated a mouse monoclonal antibody, MP-RM-1, against the extracellular domain (ECD) of ErbB-3 receptor. Assessment of human tumor cell lines, as well as early passage tumor cells revealed that MP-RM-1 effectively inhibited both NRG-1β-dependent and -independent ErbB-3 activation. The antagonizing effect of MP-RM-1 was of non-competitive type, as binding of [(125)I]-labeled NRG-1β to ErbB-3 was not influenced by the antibody. MP-RM-1 treatment led, in most instances, to decreased ErbB-3 expression. In addition, MP-RM-1 was able to inhibit the colony formation ability of tumor cells and tumor growth in two human tumor xenograft nude mouse models. Treatment with the antibody was associated with a decreased ErbB-3 and Akt phosphorylation and ErbB-3 expression in the excised tumor tissue. Collectively, these results indicate that MP-RM-1 has the potential to interfere with signaling by ErbB-3 and reinforce the notion that ErbB-3 could be a key target in cancer-drug design.

Abstract
Systemic sclerosis (SSc) is associated with interstitial lung diseases. The primary endpoints of this study were changes between baseline and month 24 in single-breath carbon monoxide diffusing capacity (DLco). The secondary endpoints were: vital capacity (VC), forced expired volume in 1 sec (FEV1), total lung capacity (TLC), scores of high resolution computed tomography (HRCT) of the chest, number of adverse effects. In this study, we retrospectively investigated data from SSc patients who had undergone therapy with high-dose intravenous N-acetylcysteine (NAC) at a dosage of 15 mg/Kg/h for 5 consecutive hours every 14 days. After NAC therapy median values of DLco (69.5% vs 77.7%), VC (99% vs 101.3%) and TLC (93% vs 98.3%) significantly increased. We did not observed any significant changes from baseline in FEV1 value and HRTC score. The improvement in lung function was more evident in SSc patients without radiological signs of pulmonary fibrosis than in patients with pulmonary fibrosis. In SSc patients with mild-moderate pulmonary fibrosis intravenous NAC administration slows the rate of deterioration of DLco, VC and TLC. In conclusion, this retrospective study demonstrates that long-term therapy with intravenous NAC ameliorates pulmonary function tests in SSc patients.

Abstract
This paper explores physical signalling in biological communications, the so-called biophysical pathways, and especially the role of electromagnetic signalling in cell-cell interactions. The experiments were designed to evaluate whether different cell populations physically interfere when incubated in separate Petri dishes placed in close proximity. Two different cell populations, immortalized mouse fibroblasts (NIH3T3) and adult human microvascular endothelial cells (HMVECad) were selected and seeded in separate polystyrene Petri dishes. Dishes seeded with NIH3T3 were then placed on top of those seeded with HMVECad at distances of 4mm and 11mm. A black filter was placed between dishes containing the two cell populations in another experiment, to prevent transmission of electromagnetic radiation between the two. Cell number and morphology of NIH3T3 and endothelial cells were found to be modified in dishes without the black filter, suggesting that specific signals emitted by the cells were transmitted through the polystyrene wall, affecting cell proliferation rate and morphology, even though the cells were growing in separate dishes.

Abstract
PURPOSE This study aimed to assess the usefulness and advantages of multiplanar reformations (MPR) during multidetector-row computed tomography (MDCT)-guided percutaneous fine-needle aspiration biopsy (FNAB) and core biopsy of retroperitoneal lesions that are difficult to access with the guidance of ultrasound and axial CT alone owing to overlying bony structures, large vessels or abdominal organs. MATERIALS AND METHODS MDCT-guided retroperitoneal FNAB and core biopsy was performed on 14 patients with suspected retroperitoneal neoplasm. We used MPR images (sagittal and coronal) obtained with a six-detector-row MDCT scanner and 20-22 gauge Chiba needles. RESULTS Using MDCT with 3D MPR allowed biological samples to be obtained in all cases (ten cytological and four histological) and diagnostic samples in 11/14 cases (78.5%). Histological samples were deemed adequate for diagnostic assessment in all cases and cytological samples in 7/10 cases (70%). CONCLUSIONS MPR images allowed sampling of retroperitoneal lesions until now considered unreachable with the guidance of axial MDCT alone. Compared with the conventional procedure, the use of MPR images does not increase the procedure time.

Abstract
Resveratrol is a phytoalexin with antioxidant properties. We evaluated resveratrol toxicity in swim-up selected human sperm and in rat spermatocytes and spermatids separated by the STAPUT method. Resveratrol antioxidant activity was tested against lipid peroxidation (LPO) induced by tert-butyl hydroperoxide. LPO was evaluated using the C11-BODIPY(581/591) probe and transmission electron microscopy in samples incubated with and without resveratrol. LD50 for human sperm and rat spermatids was 50 μM; spermatocytes were more sensitive to resveratrol cytotoxicity. Sperm motility increased progressively at 30 μM, 15 μM and 6 μM. 15 μM resveratrol acts against LPO, preserving sperm chromatin and plasma membranes. LPO were more marked in spermatocytes than in spermatids and the effect of resveratrol was more evident in spermatocytes. In this study, the scavenger properties of resveratrol were demonstrated in vitro in human sperm and rat germ cells, thus resveratrol could be added to the media used in assisted reproduction techniques and cryopreservation when oxidative stress is exacerbated.

Abstract
Borrelia burgdorferi sensu lato is a genetically diverse group of spirochetes that includes the agent of Lyme borreliosis in which genospecies tend to be associated with specific clinical features. The aim of the study was to determine the prevalence and genetic diversity of Borrelia burgdorferi sensu lato in 524 ticks collected in woods of a western province of Belgium. Presence of spirochetes in ticks was determined by phase contrast microscopy. The mean infection rate of ticks was 12.0%. Variability was observed in the prevalence of infection among the five sites examined, ranging from 2.8 to 21.6%. Identification to genospecies was determined by PCR and sequencing. The most common genomospecies were Borrelia afzelii (55%) and Borrelia garinii (21%). For the first time in Belgium, we detected Borrelia valaisiana and Borrelia spielmanii, representing 14% and 2%, respectively. Borrelia burgdorferisensu stricto counted only for 2%. Co-infections were present in 8% of ticks. We emphasize the need for clinical studies to assess the prevalence of specific genospecies-related clinical manifestations of Lyme borreliosis in Belgium.

Abstract
Neonatal bacterial meningitis (NM) continues to be a serious disease with an unchanging rate of adverse outcome of 20-60%, despite a worldwide decline in mortality. The 3 major pathogens in developed countries are: Group B streptococcus, gram negative rods and Lysteria monocytogenes. Signs and symptoms of NM may be subtle, unspecific, vague, atypical or absent. In order to exclude NM, all infants with proven or suspected sepsis should undergo lumbar puncture. Positive culture of cerebrospinal fluid may be the only way to diagnose NM and to identify the pathogen, as CSF parameters Smay be normal at early stages and NM may occur frequently (up to 30% of cases) in the absence of bacteraemia. When NM is suspected, treatment must be aggressive, as the goal is to achieve bactericidal concentration of antibiotics and to sterilize CSF as soon as possible. Antibiotics should be administered intravenously, at the highest clinically validated doses. Empiric antibiotic treatment should include agents active against all main pathogens; currently the recommended empiric treatment of NM is ampicillin, plus an aminoglycoside and a third-generation cephalosporn. Therapy should be reassessed after cultures and antibiotic susceptibility is available. Prevention of neonatal sepsis, early recognition of infants at risk, prompt treatment and future adjunctive therapies will improve prognosis. Finally, we present the first preliminary Italian data on GBS meningitis. Data are obtained from an area-based study conducted In Emilia-Romagna during 2003 to 2009.

Abstract
There is considerable interest in alternative/adjuvant approaches for the eradication of Helicobacter pylori using biologically active compounds, especially antioxidants from plants. In the present work, we tested the antioxidant and antimicrobial activities of hydro-alcoholic extracts from Colorino, Sangiovese and Cabernet Sauvignon grape cultivars against H. pylori G21 (cagA-negative, cagA-) and 10K, (cagApositive, cagA+) clinical isolates. We determined the minimum bactericidal concentration (MBC) by incubating strain suspensions in Brucella broth with fetal bovine serum and samples at different concentrations in a final volume of 100 microl in a microaerobic atmosphere. After incubation, subcultures were carried out on Brucella agar plates which were incubated for 3-5 days in a microaerobic environment. The lowest concentration in broth, where the subculture on agar showed complete absence of growth, was considered the MBC.The Colorino extract showed the highest antibacterial activity against G21 strain (MBC=1.35 mg/ml), while Sangiovese and Carbernet MBCs were 4.0 mg/ml ca. H. pylori 10K was only susceptible to Colorino after 48 hours (MBC = 3.57 mg/ml). Resveratrol exhibited the highest antibacterial activity. interestingly, the most pathogenic strain (10K) was less susceptible to both the grape extracts and the isolated compounds. These results suggest that the administration of grape extracts and wine constituents, in addition to antibiotics, might be useful in the treatment of H. pylori infection. Should the reduced susceptibility of 10K strain be extended to all the cagA+ H. pylori isolates, which are endowed with cancer promoter activity, this observation may help explain why the organisms expressing CagA are more closely associated with atrophic gastritis and gastric carcinoma development.

Abstract
OBJECTIVE Paraneoplastic neurological syndromes (PNS) probably result from an immune reaction against antigens shared by the nervous system and tumour cells. To characterise CSF alterations in these syndromes, we studied a large series of paraneoplastic patients. METHODS Using the PNS European database which includes patients diagnosed with PNS in Europe, we reviewed the clinical data of all patients included between 2000 and 2007 for which information on CSF was available. Patients were studied if they met the following inclusions criteria: (1) definite paraneoplastic disease with anti-Hu, anti-Yo, anti-CV2, anti-Ri anti-Ma/Ta and anti-Tr antibodies; (2) clinical information available; and (3) at least one CSF study. RESULTS 295 patients met the inclusion criteria. Abnormal CSF (pleiocytosis and/or high protein level and/or oligoclonal bands) was found in 93% of patients. Pleiocytosis, but not hyperproteinorachia, was more frequently seen in patients in whom the CSF study was done early in the evolution. In 24 patients, oligoclonal bands were the only abnormality found in the CSF (10%). Elevated numbers of cells were found in 47% of patients before the third month compared with 28% after the third month (p<0.01). This evolution might suggest a subacute inflammation phase within the nervous system, followed by a non-inflammatory phase. The inflammation profile was similar in all antibody types, cancers or neurological syndromes of the PNS. Surprisingly, anti-Hu patients with high pleiocytosis at the time of diagnostic had a better survival in this study than those without pleiocytosis (572 days vs 365 days; p = 0.05). CONCLUSION CSF inflammation is a common finding in PNS patients and can be a helpful tool for diagnosis, especially if this analysis is done within 3 months after neurological onset.

Abstract
AIM A continuous infection surveillance program was conducted by GiViTI throughout 2006 in Intensive Care Units (ICUs). METHODS This was a prospective epidemiological study carried out in 125 Italian intensive care units. All patients have been included in the study. Aside from the detailed clinical information collected for all patients, in cases of infection upon ICU admission and for the first site-specific episode that occurred during the patient's stay, the following data were collected: severity upon admission, micro-organisms and their antibiotic resistance patterns, subsequent multiple episodes in the same site, origin of infections and maximum severity reached. The diagnostic criteria for all infections are explicitly stated. RESULTS A total of 34,472 patients entered the study. Infection upon admission was present in 12.6% of patients, with a high level of ICU and hospital mortality (29.4% and 38.7%, respectively). In 3148 patients one or more infections were reported as ICU-acquired with an overall incidence of 9.1% and an ICU and hospital mortality of 27.2% and 35.1%, respectively. Out of the device-related infections, ventilator-associated pneumonia was the most frequently diagnosed (8.9/1000 days on ventilator). Catheter-related blood stream infection was reported with a low incidence (1.9/1000 central venous catheter days). Nearly 20% of more than 5000 isolated microorganisms were classified as multi-drug resistant, with methicillin-resistant Staphylococcus aureus as the most frequently reported bug. CONCLUSIONS The ad hoc expanded GiViTI software "Margherita2" allows continuous infection surveillance in Italian ICUs, annually providing an extensive and updated database. Interventions to improve infection prevention and patient safety should be tailored to accommodate these data.

Abstract
INTRODUCTION In idiopathic Parkinson's disease (PD), two different clinical phenotypes are usually distinguished: a tremor dominant variant (TD) and an akinetic-rigid type (ART). TD patients are characterized by a slower disease progression and a minor cognitive impairment. Striatal density of DAT, as quantified by FP-CIT SPECT, has been reported to correlate with rigidity and akinesia but not with tremor. OBJECTIVE To evaluate FP-CIT uptake in TD and ART phenotypes. METHODS We retrospectively evaluated from our database the pre-synaptic nigro-striatal function of 24 patients with TD-PD and 38 patients with ART-PD who underwent a FP-CIT SPECT within 1 year from disease onset. RESULTS Disease duration, age at the time of SPECT scan and disease severity as measured with Unified Parkinson's Disease Rating scale part III (UPDRS III) were not statistically different between the two groups. Putamen contralateral to the most clinically affected side showed a lower FP-CIT uptake in ART patients compared to TD patients. No statistically significant differences emerged when considering bilateral caudate and ipsilateral putaminal uptake, as well as asymmetry indices and caudate/putamen ratios. FP-CIT contralateral putaminal uptake correlated with the severity of rigidity and hypokinesia but not with tremor. CONCLUSIONS These data suggest that other neurotransmitter systems apart from the nigro-striatal dopaminergic system are involved in the generation of Parkinsonian tremor, and they are consistent with previous evidence of a lack of correlation between tremor severity and FP-CIT uptake. Putaminal relative sparing in TD patients could partially explain the slower disease progression reported in this PD phenotype.
