Abstract
IntroductionNon-suicidal self-injury (NSSI) is a clinical condition defined as intentional, self-inflicted act causing pain or superficial damage without suicidal intents (12-35% of the adolescent community). Several findings show a high correlation between NSSI and impairments in the impulsivity control.ObjectivesThe goal of our study is to evaluate the role of impulsivity in NSSI adolescents, relatively to the inhibitory control, in order to investigate if it can represent a neurocognitive risk factor underlying maladaptive behaviours and which psychopathological dimensions can be associated with this neurobiological process.Methods30 NNSI inpatients (age range: 12 to 18 years), drug-free, were compared with an age-matched control group, using two behavioural paradigms for the study of inhibitory control: the Stop Signal task and the emotive go/Nogo. Psychopathological traits were evaluated by self-report questionnaires for impulsivity dimensions, suicidality and self-injurious acts. Statistical analyses were performed with SPSS program (p =0.05).ResultsNSSI patients did not present impairments in the global inhibitory control but they had longer movement times in both paradigms and faster reaction times in the Go/no-go behavioural paradigm. Therefore, NSSI patients tended to be impulsive at an early stage of movement (rapid TR) and have to slow down in a second phase (TM slow) in order to have time to rework the cognitive processes underlying movement.ConclusionsThe impulsivity dimension is a complex construct that involves multiple interconnected factors. The study of neuro-cognitive and psychopathological aspects and how they are interconnected is necessary to draw new perspectives on the etiopathogenesis of NNSI.

Abstract
BACKGROUND AND PURPOSE Hereditary ataxias are heterogeneous groups of neurodegenerative disorders, characterized by cerebellar syndromes associated with dysarthria, oculomotor and corticospinal signs, neuropathy and cognitive impairment. Recent reports have suggested mutations in the SPG7 gene, causing the most common form of autosomal recessive spastic paraplegia (MIM#607259), as a main cause of ataxias. The majority of described patients were homozygotes or compound heterozygotes for the c.1529C>T (p.Ala510Val) change. We screened a cohort of 895 Italian patients with ataxia for p.Ala510Val in order to define the prevalence and genotype-phenotype correlation of this variant. METHODS We set up a rapid assay for c.1529C>T using restriction enzyme analysis after polymerase chain reaction amplification. We confirmed the diagnosis with Sanger sequencing. RESULTS We identified eight homozygotes and 13 compound heterozygotes, including two novel variants affecting splicing. Mutated patients showed a pure cerebellar ataxia at onset, evolving in mild spastic ataxia (alternatively) associated with dysarthria (~80% of patients), urinary urgency (~30%) and pyramidal signs (~70%). Comparing homozygotes and compound heterozygotes, we noted a difference in age at onset and Scale for the Assessment and Rating of Ataxia score between the two groups, supporting an earlier and more severe phenotype in compound heterozygotes versus homozygotes. CONCLUSIONS The SPG7 c.1529C>T (p.Ala510Val) mutants accounted for 2.3% of cerebellar ataxia cases in Italy, suggesting that this variant should be considered as a priority test in the presence of late-onset pure ataxia. Moreover, the heterozygous/homozygous genotype appeared to predict the onset of clinical manifestation and disease progression.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children and an important cause of short and long-term disability. In a recent systematic review of population based studies, the epidemiology of JIA is variable worldwide with incidence rates ranging between 1.6 and 23.0/100,000, and prevalence rates between 3.8 and 400.0/100,000. We investigate the incidence and describe the characteristics of juvenile idiopathic arthritis in the pediatric population of the central Italy, in the period 2000-2009. METHODS A retrospective study was conducted in the Marche region to identify patients with a diagnosis of juvenile idiopathic arthritis according to ILAR criteria, between January 1, 2000 and December 31, 2009. JIA was classified according to the ILAR criteria, that is, arthritis of unknown etiology that persisted for > 6 weeks with onset before the age of 16 years. The pooled global ascertainment of cases was estimated by capture-recapture methods and two independent information sources of ascertainment of new cases of JIA were considered. RESULTS We studied 151 patients (56 males, 37.1% and 95 females, 62.9%) meeting the ILAR criteria of juvenile idiopathic arthritis. Mean age at presentation was 6.8 ± 3.7 years for males and 6.0 ± 4.0 years for females (p=0.22). The overall incidence rate was 6.34 per 100,000/year (C.I. 6.26-7.35) and the total incidence rate increase from 2000-2009 was 8.16%. Oligoarthritis was the most common onset type (n=98, 65.0%) with 62.5% of ANA-positive patients in at least two determinations. CONCLUSIONS Our results indicate that juvenile idiopathic arthritis incidence rates in Italy are comparable to previous data from southern Europe, with a higher frequency of oligoarthritis. To the best of our knowledge, this is the first population-based epidemiological study carried out in Italy focusing on the incidence of juvenile idiopathic arthritis.

Abstract
BACKGROUND Array-comparative genomic hybridization (array-CGH) is a widely used technique to detect copy number variants (CNVs) associated with developmental delay/intellectual disability (DD/ID). AIMS Identification of genomic disorders in DD/ID. MATERIALS AND METHODS We performed a comprehensive array-CGH investigation of 1,015 consecutive cases with DD/ID and combined literature mining, genetic evidence, evolutionary constraint scores, and functional information in order to assess the pathogenicity of the CNVs. RESULTS We identified non-benign CNVs in 29% of patients. Amongst the pathogenic variants (11%), detected with a yield consistent with the literature, we found rare genomic disorders and CNVs spanning known disease genes. We further identified and discussed 51 cases with likely pathogenic CNVs spanning novel candidate genes, including genes encoding synaptic components and/or proteins involved in corticogenesis. Additionally, we identified two deletions spanning potential Topological Associated Domain (TAD) boundaries probably affecting the regulatory landscape. DISCUSSION AND CONCLUSION We show how phenotypic and genetic analyses of array-CGH data allow unraveling complex cases, identifying rare disease genes, and revealing unexpected position effects.

Abstract
Chromosomal region 1p22 is deleted in ≥20% of multiple myeloma (MM) patients, suggesting the presence of an unidentified tumor suppressor. Using high-resolution genomic profiling, we delimit a 58 kb minimal deleted region (MDR) on 1p22.1 encompassing two genes: ectopic viral integration site 5 (EVI5) and ribosomal protein L5 (RPL5). Low mRNA expression of EVI5 and RPL5 was associated with worse survival in diagnostic cases. Patients with 1p22 deletion had lower mRNA expression of EVI5 and RPL5, however, 1p22 deletion status is a bad predictor of RPL5 expression in some cases, suggesting that other mechanisms downregulate RPL5 expression. Interestingly, RPL5 but not EVI5 mRNA levels were significantly lower in relapsed patients responding to bortezomib and; both in newly diagnosed and relapsed patients, bortezomib treatment could overcome their bad prognosis by raising their progression-free survival to equal that of patients with high RPL5 expression. In conclusion, our genetic data restrict the MDR on 1p22 to EVI5 and RPL5 and although the role of these genes in promoting MM progression remains to be determined, we identify RPL5 mRNA expression as a biomarker for initial response to bortezomib in relapsed patients and subsequent survival benefit after long-term treatment in newly diagnosed and relapsed patients.

Abstract
The microbial ecosystem of the gastrointestinal tract is characterized by a great number of microbial species living in balance by adopting mutualistic strategies. The eubiosis/dysbiosis condition of the gut microbiota strongly influences our healthy and disease status. This review briefly describes microbiota composition and functions, to then focus on eubiosis and dysbiosis status: the two sides of the microbiota.

Abstract
Most present-day galaxies with stellar masses ≥10(11) solar masses show no ongoing star formation and are dense spheroids. Ten billion years ago, similarly massive galaxies were typically forming stars at rates of hundreds solar masses per year. It is debated how star formation ceased, on which time scales, and how this "quenching" relates to the emergence of dense spheroids. We measured stellar mass and star-formation rate surface density distributions in star-forming galaxies at redshift 2.2 with ~1-kiloparsec resolution. We find that, in the most massive galaxies, star formation is quenched from the inside out, on time scales less than 1 billion years in the inner regions, up to a few billion years in the outer disks. These galaxies sustain high star-formation activity at large radii, while hosting fully grown and already quenched bulges in their cores.

Abstract
Staphylococcus haemolyticus strains (n=20), responsible of blood stream infections, were consecutively isolated from patients hospitalized in two different wards at high risk of infection. Strains displayed high rate of resistance to oxacillin (90%). All strains but two with decreased susceptibility (MIC = 4 microg/mL), were sensitive to vancomycin. Ten strains were resistant to teicoplanin. Among the strains susceptible to glycopeptides, three displayed heteroresistance to vancomycin and seven to teicoplanin, when tested by Etest technique with 2 x McFarland inoculum. Biochemical reactions allowed to assign strains to eight biotypes, with 11 strains clustering under two main biotype A and biotype B. Pulsed-field-gel-electrophoresis (PFGE) identified 11 different PFGE-types. Seven strains grouping under the major PFGE-type 1 and three strains clustering in PFGE-type 2, closely correlated to biotype A and biotype B respectively. Seven teicoplanin-resistant isolates clustered in the PFGE-type 1, two in the PFGE-type 2 and one in PFGE-type 5. Therefore, teicoplanin-resistant strains were biochemically and genetically related and clonally distributed, despite different clones of S. haemolyticus circulated in the units during the study period.

Abstract
Acute renal dysfunction (ARD) is a common complication in renal transplant recipients. Multiple factors contribute to ARD development, including acute rejection and microbial infections. Many viral infections after kidney transplantation result from reactivation of “latent” viruses in the host or from the graft, such as the human Polyomavirus BK (BKV). We report the case of a 39 year-old recipient of a 2nd kidney graft who experienced BKV reactivation after a second episode of acute humoral rejection. A 10-day treatment with the quinolone antibiotic ciprofloxacin was administered with an increase of immunosuppressive therapy despite the active BKV replication. Real Time PCR analysis performed after treatment with ciprofloxacin, unexpectedly showed clearance of BK viremia and regression of BK viruria. During the follow-up, BK viremia persisted undetectable while viruria decreased further and disappeared after 3 months. BKV non-coding control region sequence analysis from all positive samples always showed the presence of archetypal sequences, with two single-nucleotide substitutions and one nucleotide deletion that, interestingly, were all representative of the subtype/subgroup I/b-1 we identified by the viral protein 1 sequencing analysis. We report the potential effect of the quinolone antibiotic ciprofloxacin in the decrease of the BKV load in both blood and urine.

Abstract
Both hyperthyroidism and hypothyroidism produce changes in cardiac contractility, myocardial oxygen consumption, cardiac output, blood pressure, and systemic or pulmonary vascular resistance. In almost all cases these cardiovascular changes are reversible when the underlying thyroid disorder is recognized and treated. Pulmonary hypertension (PAH) has been associated with thyroid dysfunction, but primarily with hyperthyroidism. The vast majority of patients with this form of PAH are usually older with toxic multinodular goitre. Data currently available suggest a direct influence of TH on pulmonary vasculature. Possible mechanisms include: 1) enhanced catecholamine sensitivity, causing pulmonary vasoconstriction, a reduction in pulmonary vascular compliance and an increase in vascular resistance; 2) increased metabolism of intrinsic pulmonary vasodilating substances (prostacyclin, nitric oxide); 3) decreased or impaired metabolism of vascontrictors (serotonin, endothelin 1 and tromboxane). In some cases (Graves's and Hashimoto's disease) and an autoimmune process inducing endothelial damage may play a key role. Future studies should focus on discovering the immunogenetic overlap between autoimmune thyroid diseases and PAH: common human leukocyte antigen alleles, susceptibility loci and so on. Such an understanding of the genetic and immune factors may ultimately lead to novel effective approaches in the treatment of PAH. At present, thyroid function tests should be considered in the investigation of all patients with PAH.

Abstract
We observed five consecutive cases of Hypersensitivity Pneumonitis in subjects working in a salami factory. The workers had to clean the white mould growing on salami surface using a manual wire brush. The five patients (four female) had a mean age of 39 +/- 15 years; two were smokers. Three patients had an acute clinical presentation with fever, dyspnoea, dry cough, oxygen desaturation, and presented at the emergency department with suspected diagnosis of community acquired pneumonia. The mean latency for developing respiratory symptoms was 11.6 days. Pulmonary function test demonstrated a reduction in diffusing capacity (DLCO) in all 5 patients (60 +/- 15% of predicted value). Skin prick test was positive for Penicillium spp in 3 cases and for Cladosporium and Aspergillus spp in 2 others. Specific IgG antibodies against Penicillium spp were positive in 3 subjects; 2 were positive for Aspergillus Fumigatus. The prevailing radiological pattern was a ground glass appearance in the three patients with acute clinical onset and a centrilobular one in patients with subacute onset. All patients were advised to avoid exposure to the antigens. Follow-up visits including pulmonary function testing, and DLCO measurement were conducted at one, three and six months. HRCT was performed at six month. Four subjects had a complete radiological and clinical resolution after changing work. Only one patient was treated with oral steroids for severe dyspnoea and progressive reduction of DLCO, gaining a complete radiological and clinical stability at six months.

Abstract
Invasive pulmonary aspergillosis (IPA) is one of the major causes of morbidity and mortality in severely immunocompromised patients, but recently several authors have reported the occurrence of IPA in liver cirrhosis, chronic obstructive pulmonary disease (COPD) patients, most of whom, but not all, were receiving steroid treatment, with a very high mortality rate. The detection of galactomannan performed in respiratory specimens is a new valuable test for the diagnosis of probable IPA, even in non-neutropenic high risk patients. Since the frequency and clinical impact of IPA in non-hematologic patients is not well known, it seemed rational to us to attempt a prospective study evaluating all patients hospitalized in a university hospital for whom an infectious Diseases consultation was required. This 14-month survey in our hospital, using recently recommended diagnostic criteria, seems to suggest an emerging role of IPA in these patients who may have a higher mortality rate than their neutropenic peers, and provides preliminary evidence that early diagnosis and prompt initiation of antifungal therapy may improve the ultimate outcome of their IPA.

Abstract
Central nervous system (CNS) lymphoma is a rare posttransplant lymphoproliferative disorder (PTLD), which usually has a poor outcome. To date, no specific conditions predisposing to this complication have been identified. We here describe the case of a renal transplant patient who was initially diagnosed as having Epstein-Barr virus (EBV)-associated leukoencephalopathy and ultimately developed EBV-positive CNS lymphoma. The patient was a young lady who, 2 years after transplantation, presented with focal neurological and electroencephalographic abnormalities and diffuse white matter lesions on brain magnetic resonance imaging. EBV-DNA was detected in the cerebrospinal fluid (CSF) by polymerase chain reaction. After acyclovir therapy and immunosuppressive drug tapering, the symptoms and electroencephalographic abnormalities subsided, and EBV-DNA disappeared from the CSF. Ten years later, a bulky cerebral mass was found. After excision, a diagnosis of EBV-positive, Hodgkin-like monomorphic B-cell PTLD was made. This case illustrates the potential pathophysiological relationships between EBV infection, leukoencephalopathy and CNS lymphoma; although a long time elapsed from the initial neurological illness to CNS lymphoma, a link between these two conditions cannot be excluded. Therefore, a careful long-term follow-up of EBV-related encephalopathy is advisable.

Abstract
Human herpesviruses (HHVs) cause many serious acute and persistent central nervous system (CNS) disorders. Because these infections manifest with various, often non-specific, symptoms and signs, and because specific therapy is often available, accurate diagnosis is essential. Cerebrospinal fluid (CSF) from 146 patients with acute meningitis or meningoencephalitis and 9 with "other neurological disorders" were analyzed by using an automatic system for nucleic acid extraction and quantitative real-time polymerase chain reaction (PCR) for herpes simplex 1 and 2 (HSV-1, HSV-2), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), herpesvirus-6 (HHV-6), and varicella-zoster virus (VZV). HHVs DNA was detected in 52 of 155 (33.5%) analyzed samples. In 39 CSF samples from patients with meningoencephalitis we found: VZV in 13, HSV-1 in 12, EBV in 6, HHV-6 in 4, and HSV-2 in 4. Co-infections of EBV and HSV-2, HSV-1 and HSV-2, HSV-1 and VZV were also disclosed in four cases. In addition, two patients with Guillain-Barré syndrome had HCMV and one showed HHV6 positivity, two patients with myelitis / polymyeloradiculitis had VZV and HCMV respectively, HHV-6 DNA was found in one patient with lateral amyotrophic sclerosis. Three CSF specimens from HIV-infected patients with CNS complications had HHV-6 or EBV DNA. Moreover quantitative data were also correlated to clinical conditions to obtain more information on the virus aetiopathogenic role.

Abstract
OBJECTIVES To ascertain whether cystic fibrosis (CF) patients are colonized or infected with unique or multiple strains of Stenotrophomonas maltophilia; to understand whether some strains colonize or infect more than 1 patient, indicating clonal spread; and to explore the molecular heterogeneity of hospital water isolates and their correlation with clinical isolates. SETTING The regional CF center of Policlinico "Umberto I" of Rome, Italy. METHODS The study was carried out on a random sample of S. maltophilia isolates (n = 110) collected from CF patients (n = 50) during the period 2002-2005 and on 24 water isolates obtained during a monitoring program in the first 6 months of 2005. Home environmental samplings were not performed. All isolates, which were recovered from cultures of specimens obtained in both inpatient and outpatient settings, were genotyped with DNA macrorestriction analysis with the restriction enzyme XbaI and pulsed-field gel electrophoresis. RESULTS One-third of the patients with repeated episodes of S. maltophilia infection or colonization hosted more than 1 strain. A potential transmission, defined as the isolation of the same strain in 2 or more patients, occurred 5 times, showing a frequency of potential transmission episodes slightly higher than previously reported. Water, taps, and sinks of the different rooms of the CF center tended to be persistently colonized with the same strain of S. maltophilia, with no correlation between clinical and water-associated isolates. CONCLUSIONS The study does not provide sufficient data to conclude definitively that isolation of colonized or infected CF patients and control of hospital water systems contamination would be beneficial infection control measures. Epidemiologic analytical studies that correlate the presence of S. maltophilia with clinical outcomes are strongly needed.

Abstract
Carbapenem-resistant Acinetobacter baumannii was isolated from 15 colonized or infected patients (carriers) between April and July 2004, in a teaching hospital ICU in Rome, Italy. All isolated strains were susceptible only to gentamicin, ampicillin-sulbactam and colistin and displayed the same Random Amplified Polymorphic DNA (RAPD) 1 pattern. Twelve out of 15 strains were susceptible to tigecycline, whereas the remaining three showed intermediate susceptibility. Although infection control measures were reinforced and carriers isolated in separate rooms, A. baumannii transmission continued. Therefore, finally A. baumannii carriers were moved to another available subintensive unit, which was re-equipped, and cared for by dedicated personnel, whereas only the non infected/colonized patients remained in the ICU. This study shows that during an outbreak by multiresistant A. baumannii it may be indispensable to geographically isolate not only patients but also dedicated staff.

Abstract
In this study 45 epidemic and sporadic isolates of Acinetobacter baumannii were investigated by antimicrobial resistance, integron identifications and genotyping. Isolates were genotyped by random amplified polymorphism (RAPD) DNA and pulsed-field gel electrophoresis (PFGE). Four different RAPD patterns were observed among the isolates of our collection, further discerned in six PFGE types. Two prevalent genotypes were identified, one corresponding to a carbapenem resistant epidemic clone, causing an outbreak at the intensive care unit of a hospital of Rome. Two class 1 integrons, carrying different gene cassette arrays, were identified among the two prevalent genotypes. Nucleotide analysis of the integron-variable regions revealed the presence of the aacA4, orfO, bla(OXA-20), and aacC1, orfX, orfX', aadA1 gene cassette arrays, respectively. All the carbapenem resistant strains analyzed in this study carried the bla (OXA-58) gene located on plasmids.

Abstract
Hepatitis E Virus (HEV) infections are responsible for large waterborne outbreaks in developing countries. Sporadic cases in the developed world are mainly imported from endemic areas. HEV has been suggested to be a zoonotic infection, for which pigs may be the reservoir; specific swine strains of HEV have been identified. Humans are susceptible to infections with swine strains. The aim of this study was to analyse whether Italian pig farmers, veterinarians and abattoir workers are more exposed than persons with other occupations. A total of 92 workers at zoonotic risk and 3511 controls from the general population of two Latium cities, Rome and Rieti, were tested for IgG-HEV antibodies. No significant difference in anti-HEV prevalence was observed between the two groups. The prevalence of general population was 2.9% against 3.3% of pig breeders, while there was a statistically significant difference (p = .0004) between subjects recruited in Rome (prevalence 2.5%) and those recruited in Rieti (prevalence 5.5%). Moreover, in some subgroups of general population and in a subgroup of pig breeders, the prevalence was higher than that previously reported in Italy and in other European countries. The highest value (33%) was found in male housekeepers enrolled in Rome; an analogous value was found in the employees of abattoirs (33%). Further studies are needed to elucidate the transmission routes.

Abstract
We examined the frequency of isolation and the antimicrobial resistance of Burkholderia cepacia complex, Stenotrophomonas maltophilia and Achromobacter xylosoxidans in cystic fibrosis patients from 2000 to 2004. Strains susceptibility to tobramycin, piperacillin/tazobactam, imipenem, gentamicin, ciprofloxacin and ceftazidime was determined by disc diffusion assay. B. cepacia complex showed a very high resistance also to ciprofloxacin reaching 100% in 2004. S. maltophilia and A. xvylosoxidans showed high rates of antimicrobial resistance both aminoglycoside and ciprofloxacin. It is very important to monitor the percentage of isolation of these species over time to verify strains resistance to antibiotics and also to test new combinations of antimicrobial agents.

Abstract
Transplant patients are at high risk of post-transplant lymphoproliferative disorder (PTLD). A strong correlation between Epstein-Barr virus (EBV) and PTLD is observed in pediatric patients with primary infection after transplant. Because many patients have responded to reversal of immunosuppressive therapy, an early identification of EBV is essential for the reduction of immunosuppression and/or introduction of antiviral therapy to prevent PTLD. Polymerase chain reaction (PCR) is a specific and sensitive method to identify EBV DNA in blood. The aim of our study was to establish a protocol for monitoring EBV infection in transplanted patients for early identification those at high risk of PTLD. Viral presence in peripheral blood leukocytes (PBL) and serum samples was revealed by Nested PCR; positive specimens were quantified with Real Time PCR (RT-PCR). DNA in PBL was observed in 12 cases and 6 showed EBV in sera. Quantitative analysis showed a wide range of EBV DNA copies in leukocytes that were higher than in sera. Two patients displayed high viral load values in both PBL and sera associated with clinical evidence of PTLD. Our data suggest that the study of the EBV load represents an essential approach in the diagnosis of PTLD and the analysis of serum samples could provide useful information in the post-transplant monitoring of high-risk patients.

Abstract
Epstein Barr Virus (EBV), is associated with an increasing number of lymphoid and epithelial malignancies. Among the genes expressed by EBV during latency, LMP1 plays a key role for growth transformation and immortalization of B lymphocytes. We have previously shown that antisense oligonucleotides (ONs) directed to LMP1 mRNA, effectively suppressed LMP1 gene expression and substantially reduced proliferation of the infected cells. The use of antisense phosphodiester oligonucleotides as therapeutic agents is limited by inefficient cellular uptake and intracellular transport to the target mRNA. We tested the ability of three cationic carriers internalized by different pathways, to increase the delivery of anti-LMP1-ON to their site of action in EBV-infected B lymphocytes. We report here that liposomes, dendrimers or transferrin-polylysine-conjugated ON were internalized by the cells at an extent several fold higher than that of the naked oligomers. However, only the delivery system exploiting the transferrin receptor pathway of internalization, was able to vectorize biologically active antisense LMP1-ON.

Abstract
Immunosuppressive status in solid organ transplant recipients is often related to the reactivation of Human Cytomegalovirus (HCMV) infection that remains one of the major causes of morbidity and mortality. Therefore, the early detection of HCMV followed by infection monitoring is important to institute prompt and appropriate treatment. In recent years good results have been obtained by HCMV DNA amplification methods; qualitative and quantitative approaches have shown good sensitivity and specificity, but they often require post-PCR manipulation that adds time to the analysis and may lead to contamination problems. Recently, Real Time PCR (RT-PCR) has been proposed in HCMV DNA analysis as a valid method for its good sensitivity and rapidity. In the present study, twenty-five solid organ transplant recipients were analyzed for HCMV diagnosis; 60 peripheral blood leukocytes and 120 plasma samples were tested by RT-PCR and the results compared to those obtained by a qualitative Nested PCR and a quantitative DNA enzyme immunoassay.

Abstract
Osteopontin (OPN) is a multifunctional bone matrix glycoprotein that is involved in angiogenesis, cell survival and tumor progression. In this study we show that human myeloma cells directly produce OPN and express its major regulating gene Runx2/Cbfa1. The activity of Runx2/Cbfa1 protein in human myeloma cells has also been demonstrated. Moreover, using small interfering RNA (siRNA) to silent Runx2 in myeloma cells, we suppressed OPN mRNA and protein expression. OPN production in myeloma cells was stimulated by growth factors as IL-6 and IFG-1 and in turn OPN stimulated myeloma cell proliferation. In an 'in vitro' angiogenesis system we showed that OPN production by myeloma cells is critical for the proangiogenic effect of myeloma cells. The expression of OPN by purified bone marrow (BM) CD138(+) cells has also been investigated in 60 newly diagnosed multiple myeloma (MM) patients, finding that 40% of MM patients tested expressed OPN. Higher OPN levels have been detected in the BM plasma of MM patients positive for OPN as compared to controls. Moreover, significantly higher BM angiogenesis has been observed in MM patients positive for OPN as compared to those negative. Our data highlight that human myeloma cells with active Runx2/Cbfa1 protein directly produce OPN that is involved in the pathophysiology of MM-induced angiogenesis.

Abstract
One hundred strains of Stenotrophomonas maltophilia isolates from respiratory specimens were biochemically identified using the API 20NE strip and the VITEK2 ID-GNB card. The identification was confirmed by a species-specific PCR using two primers specific for the 23S rRNA gene. The API 20NE showed only 1 strain with "low discrimination" whereas the VITEK2 gave 12. In any case, the two biochemical systems showed good reliability compared to SS-PCR.

Abstract
OBJECTIVE To evaluate the effect of an infection control program on the incidence of hospital-acquired infection (HAI) and associated mortality. DESIGN Prospective study. SETTING A 2000-bed, university-affiliated hospital in Italy. PATIENTS All patients admitted to the general intensive care unit (ICU) for more than 48 hours between January 2000 and December 2001. METHODS The infection control team (ICT) collected data on the following from all patients: demographics, origin, diagnosis, severity score, underlying diseases, invasive procedures, HAI, isolated microorganisms, and antibiotic susceptibility. INTERVENTIONS Regular ICT surveillance meetings were held with ICU personnel. Criteria for invasive procedures, particularly central venous catheters (CVCs), were modified. ICU care was restricted to a team of specialist physicians and nurses and ICU antimicrobial therapy policies were modified. RESULTS Five hundred thirty-seven patients were included in the study (279 during 2000 and 258 in 2001). Between 2000 and 2001, CVC exposure (82.8% vs 71.3%; P < .05) and mechanical ventilation duration (11.2 vs 9.6 days) decreased. The HAI rate decreased from 28.7% in 2000 to 21.3% in 2001 (P < .05). The crude mortality rate decreased from 41.2% in 2000 to 32.9% in 2001 (P < .05). The most commonly isolated microorganisms were nonfermentative gram-negative organisms and staphylococci (particularly MRSA). Mortality was associated with infection (relative risk, 2.11; 95% confidence interval, 1.72-2.59; P < .05). CONCLUSION Routine surveillance for HAI, coupled with new measures to prevent infections and a revised policy for antimicrobial therapy, was associated with a reduction in ICU HAls and mortality.
