Abstract
Abstract
Background
Even if the food supplement industry is one of the fastest growing worldwide, the inappropriate use of these products can potentially cause harms. Considering the key role played by pharmacists in advising citizens on the purchase of food supplements, this cross-sectional observational study evaluates pharmacists' knowledge, attitudes and practice on this topic.
Methods
From September 2020 to February 2021, an online questionnaire implemented through the EU-Survey tool, was administered to pharmacists of both public and private authorized pharmacies of the Friuli-Venezia Giulia (FVG) Region (Italy). The 47 multiple-choice questions about pharmacists' knowledge (20), attitudes and practice (27), were followed by a sociodemographic section (7 items) collecting data about sex, age, years of experience, degree, role within pharmacy (owner, employee). Descriptive analyses, Chi-square, Shapiro-Wilk and Mann Whitney tests were used and a p-value<0.05 was considered as statistically significant.
Results
A sample of 232 questionnaires was collected, 70.7% of which from women. Most responders (77.2%) had a Pharmacy degree, with owners representing the 34.5%. The 61.2% of pharmacists had at least 10 years of experience. Knowledge was generally poor with just 49.2% of the sample scoring above the median value of 11 but higher among pharmacists with more than 11 years of experience. Lesser-known aspects were the possible link between cancer and multivitamin's abuse and presence of non-labeled agents in food supplements. Responders < =10 years of experience felt more unprepared about vitamin's dosage and in counselling particular groups of patients (p < 0.05). Employees more frequently reported the attitude to purchase food supplements under patient specifical request (p < 0.05).
Conclusions
Pharmacists' knowledge about food supplements is scarce and young professionals in particular need further education to ensure a safe and effective purchase of these products to patients.
Key messages
The use of vitamin supplements is growing but their consumption needs to be evaluated by expert and qualified professionals. Pharmacists play a key role in counselling people about food supplements but need continuous professional education to give adequate advice.

Abstract
BACKGROUND Despite the high frequency of tracheotomy in severe acquired brain injury (sABI) patients, available literature about the weaning procedure is mainly represented by expert opinions with no standardized and evidence-based criteria. AIM The Institute of Physical and Rehabilitation Medicine "Gervasutta" adopted a new decannulation procedure, recommended by the Italian Society of Physical Medicine and Rehabilitation (SIMFER). This study evaluates whether the new procedure helps to improve the decannulation process of sABI patients. DESIGN A prospective observational with historical control was performed by dividing sABI patients into two groups depending on whether they were treated with or without the new procedure. SETTING The Department of Neurorehabilitation of the Institute of Physical and Rehabilitation Medicine "Gervasutta" in Udine, Italy. POPULATION sABI patients with tracheal cannula admitted to the Institute of Physical and Rehabilitation Medicine "Gervasutta" from January 2015 to March 2019. METHODS Clinical data were collected as both process and outcome indicators before and after the adoption of the new procedure. Data have been processed with Simple Interactive Statistical Analysis (SISA; Irving, TX, USA) software. RESULTS A sample of 141 patients was analysed. Among the 141 patients, 57 (40.4%) were treated with the new procedure. No differences were found between the two groups in terms of complications, functional independence measure (FIM), or level of cognitive functioning (LCF) at the admission. When the new procedure was applied, the decannulation rate was significantly higher (OR=1.8; 95% CI=1.2-9.8; P=0.01) and the time (days) between admission and oral feeding resumption was significantly lower (P<0.001; 95% CI=-10, -34 days). CONCLUSIONS The introduction of the new protocol allowed the safe achievement of both oral feeding resumption and decannulation, which are two of the main early rehabilitation goals. CLINICAL REHABILITATION IMPACT The standardization of the decannulation process has determined the achievement of a significantly faster oral feeding resumption and an increase in the decannulation rate during the rehabilitation of sABI patients.

Abstract
BACKGROUND Marginal bone loss (MBL) represents an important indicator of peri-implant health and the measure of its level is considered a determining factor in the evaluation of the quality of survival. Aim of this study is to compare radiographic changes in the fractal and mesial/distal vertical dimensions of peri-implant trabecular bone of dental implants with a laser-ablated micron-scale modication (LAM) of collar surface after a 5-year follow-up period. MATERIALS AND METHODS Thirty-four implants with LAM of collar surface (test group = TG) and 31 implants without LAM of collar surface (control group = CG) were placed in 45 non-smoking, periodontally healthy patients. Fractal and vertical dimensions of peri-implant trabecular bone were measured by comparing radiographs taken immediately after prosthesis delivery with those taken 3 years and 5 years after functional loading. RESULT At the end of the 5-year follow-up, the MBL in the TG was 0.87±0.21 and 0.75±0.25 mm at the mesial and distal aspects, respectively, while a MBL of 2.05±0.25 mm at the mesial aspect and 2.01±0.34 mm at the distal site was recorded in the CG. A statistically significant difference was noted. In the TG the mean fractal dimension before loading was 1.4213±0.0525. It increased significantly to 1.4329±0.0479 at 3 years after loading and remained almost stable at 5 years after loading (1.4327±0.0291). In the CG the mean fractal dimension before loading was 1.4119±0.0414. It increased significantly to 1.4282±0.0324 at 3 years after loading and decreased significantly to 1.4111±0.0624 at 5 years after loading. At the end of the follow-up, differences between both study groups were statistically significant. CONCLUSION The increased fractal dimension and the reduced MBL around TG implants after 5 years of functional loading indicates a positive effect of a laser-ablated micron-scale modication of collar surface on peri-implant trabecular bone remodeling.

Abstract
Background: Despite the free-of-charge offer of influenza vaccines to at-risk subgroups, vaccine coverage remains low and far from the target, probably due to the false myths and misperceptions. We aimed to explore the healthcare students’ vaccination behavior and beliefs to find any association between vaccination uptake during the last 5 years and future vaccination acceptance.
Study design: A multicentre cross-sectional study.
Methods: From Oct 2017 to Nov 2018, the Italian healthcare students from 14 different universities in 2017/2018 were enrolled, through an online and anonymous questionnaire previously validated. Absolute and relative frequencies were calculated and Pearson's Chi-square test was used. A multinomial logistic regression model was performed. Results are expressed as relative Risk Ratio (RR) with 95% Confidence Intervals (95% CI). The level of significance chosen was P-value <0.05.
Results: A total of 3137 students were enrolled and 3131 questionnaires were analysed. 82.7% of the sample declared they had not received any flu vaccination during the last 5 years. Students who received flu vaccination 4 times or more during the last 5 years were more likely to do it again next year as well (95.1% vs 4.9%). The regression model showed that having received flu vaccination over the last 5 years was statistically associated with the intention of getting vaccinated during next season.
Conclusions: Frequency of flu vaccination is predictive for future acceptance among healthcare students. This association could have both implications for the organization of vaccination campaigns and improve educational strategies for this category of students.

Abstract
Evolutionary robotics using real hardware is currently restricted to evolving robot controllers, but the technology for evolvable morphologies is advancing quickly. Rapid prototyping (3D printing) and automated assembly are the main enablers of robotic systems where robot offspring can be produced based on a blueprint that specifies the morphologies and the controllers of the parents. This article addresses the problem of gait learning in newborn robots whose morphology is unknown in advance. We investigate a reinforcement learning method and conduct simulation experiments using robot morphologies with different size and complexity. We establish that reinforcement learning does the job well and that it outperforms two alternative algorithms. The experiments also give insights into the online dynamics of gait learning and into the influence of the size, shape, and morphological complexity of the modular robots. These insights can potentially be used to predict the viability of modular robotic organisms before they are constructed.

Abstract
BACKGROUND Surveillance for hepatocellular carcinoma (HCC) is recommended in patients with cirrhosis. As α-fetoprotein (AFP) is considered a poor surveillance test, we tested the performance of its changes over time. METHODS Eighty patients were diagnosed with HCC (cases) during semiannual surveillance with ultrasonography and AFP measurement were recruited and matched for age, gender, etiology and Child-Pugh class with 160 contemporary cancer-free controls undergoing the same surveillance training group (TG). As a validation group (VG) we considered 36 subsequent patients diagnosed with HCC, matched 1 : 3 with contemporary cancer-free controls. α-Fetoprotein values at the time of HCC diagnosis (T0) and its changes over the 12 (Δ12) and 6 months (Δ6) before cancer detection were considered. RESULTS In both TG and VG, >80% of HCCs were found at an early stage. In TG, AFP significantly increased over time only in cases. T0 AFP and a positive Δ6 were independently associated with HCC diagnosis (odds ratio: 1.031 and 2.402, respectively). The area under the curve of T0 AFP was 0.76 and its best cutoff (BC) was 10 ng ml(-1) (sensitivity 66.3%, specificity 80.6%). The combination of AFP >10 ng ml(-1) or a positive Δ6 composite α-fetoprotein index (CAI) increased the sensitivity to 80% with a negative predictive value (NPV) of 86.2%. Negative predictive value rose to 99%, considering a cancer prevalence of 3%. In the VG, the AFP-BC was again 10 ng ml(-1) (sensitivity 66.7%, specificity 88.9%), and CAI sensitivity was 80.6% with a NPV value of 90.5%. CONCLUSIONS CAI achieves adequate sensitivity and NPV as a surveillance test for the early detection of HCC in cirrhosis.

Abstract
OBJECTIVE To test the hypothesis that dietary myo-inositol may improve insulin resistance and the development of gestational diabetes mellitus (GDM) in women at high risk of this disorder. DESIGN A prospective, randomized, double-blind, placebo controlled clinical trial, pilot study. PARTICIPANTS Non-obese singleton pregnant women with an elevated fasting glucose in the first or early second trimester were studied throughout pregnancy. INTERVENTION Supplementation with myo-inositol or placebo during pregnancy. MAIN OUTCOME MEASURE Development of GDM on a 75 g oral glucose tolerance test at 24-28 weeks' gestation. Secondary outcome measures were increased in BMI, need for maternal insulin therapy, macrosomia, polyhydramnios, neonatal birthweight and hypoglycemia. RESULTS Thirty-six women were allocated to receive myo-inositol and 39 placebo. The incidence of GDM in mid-pregnancy was significantly reduced (p = 0.001) in women randomized to receive myo-inositol compared to placebo (relative risk 0.127). Women randomized to receive myo-inositol also required less insulin therapy, delivered at a later gestational age, had significantly smaller babies with fewer episodes of neonatal hypoglycemia. CONCLUSIONS Myo-inositol supplementation in pregnancy reduced the incidence of GDM in women at high risk of this disorder. The reduction in incidence of GDM in the treatment arm was accompanied by improved outcomes.

Abstract
The widespread use of biotechnologies in animal breeding in Brazil has enabled greater control over the transmission of pathogens. Nevertheless, disease transmission continues to be a significant concern and justifies the search for better control agents. The objective of this study was to evaluate whether the detrimental effects of the experimental infection of oocytes with BoHV-1 (Colorado strain, 108 TCID 50 mL–1) during in vitro maturation (24 h) could be reduced by the viral inhibitor ethanolic extract of Punica granatum (PG). Cattle ovaries were obtained from a local slaughterhouse (unknown breed), and transported to the laboratory. Cumulus–oocyte complexes (COC) were aspirated from follicles and allocated into four groups, which were exposed to: 10 µL of sterile physiological solution (G1 [control], n = 125); 10 µL of PG extract in 0.01% sterile saline solution (G2, n = 149); 10 µL of BoHV-1 virus (G3, n = 151); or 10 µL of PG extract in 0.01% and 10 µL of BoHV-1 virus (G4, n = 144). All groups were matured in 100 mL of IVM for 24 h at 37.5°C, 5% CO2 in air. After in vitro maturation, we evaluated COC expansion and presence of a polar body by optical microscope, and viral replication by titration (Reed and Muench test) after 72 h co-culture with Madin-Darby bovine kidney (MDBK) cells. Differences among groups in maturation rates were compared by chi-square test, and in titration by t-test. The G1, G2, and G4 showed steady expansion of the cumulus cells and ooplasm with uniform appearance. The G3 did not show expansion of the cumulus cells and ooplasma showed degenerative appearance. The maturation rates were as follows: G1 52% (65/125); G2 45.63% (68/149); G3 27.81% (42/151); G4 41.66% (60/144). We used the χ2 test (P ≤ 0.05) for the rate of maturation and the t-test (P ≤ 0.05) for the titration data. A reduction (P ≤ 0.05) in maturation rate was observed in G3, when compared to the G1 [control]. Oocytes exposed to BoHV-1 virus and matured in the presence of PG extract (G4) had lower (P ≤ 0.05) rates of viral replication than those matured in the absence of PG (G3). These results support the conclusion that PG extract reduces the viral rate of replication without interfering in oocyte maturation, and may be an alternative to sanitary control protocols.

Abstract
O Mycoplasma é considerado cosmopolita, podendo ser disseminado através do comércio internacional de animais, sêmen industrializado e de produtos de transferência de embriões. A expansão de células do cumulus é utilizada como parâmetro de avaliação de oócitos bovinos cultivados in vitro e suas alterações morfológicas são representativas. O objetivo deste trabalho foi avaliar a interação do Mycoplasma bovigenitalium, exposto experimentalmente à cultura primária de célula do cumulus, após o período de maturação. Complexos oócitos cumulus (COCs) obtidos através de punção folicular de ovários bovinos, provenientes de abatedouro, foram divididos em dois grupos para serem maturados durante 24h em meio de maturação (TCM199 + hormônios) em estufa a 38º C, 5% de CO2, 95% de umidade. Posteriormente, os oócitos foram retirados das placas, permanecendo somente com as células do cumulus aderidas. Com o monoestrato celular formado, um grupo foi infectado com 30 mL de M. bovigenitalium, replicado em meio Hayflick modificado a 37º C em estufa de microaerofilia, enquanto o outro foi mantido como controle. Os resultados mostraram que, com 24h de exposição ao patógeno, as culturas apresentaram um pequeno número de células arredondadas e granulosas, quando comparadas as dos controles. Esse efeito persistiu até o sétimo dia, onde se iniciou um processo de descolamento das células. Pode-se concluir que uma contaminação por micoplasma pode ser imperceptível às manipulações da FIV, pois células infectadas por esse grupo de bactérias não apresentam turvações no meio de cultura e, quando não lisam a célula hospedeira, tornam mais suscetível ao ambiente e outros agentes infecciosos.

Abstract
INTRODUCTION Adequate brushing of oral mucosa is important for accurate human papillomavirus (HPV) detection in potentially malignant (oral leukoplakia [OL], oral lichen planus [OLP]) and malignant (oral squamous cell carcinoma [OSCC]) lesions. Since various factors may limit the adequacy of oral brushing and, consequently, the accuracy of HPV detection, modified sampling procedures should be evaluated for their effect on HPV frequency and/or types detected. AIM To compare the HPV frequency in samples obtained by brushing the lesion site with the frequency in samples obtained by brushing an apparently normal adjacent site. The correlation between HPV frequency and keratinization of the site affected by the lesion, as well as sociodemographic variables (age, sex, smoking and drinking habits), was also examined. METHODS HPV DNA was detected in brushing samples from 50 patients with OL, 49 with OLP, and 17 with OSCC. Polymerase chain reaction (PCR) amplification was performed by MY09/MY11 and GP05+/GP06+ primers; the HPV type was identified by DNA sequencing and a reverse hybridization (line probe) assay. Data were analyzed by the Z test, the Fisher's exact test, the chi-square test, odds ratio (OR), and a logistic regression model. RESULTS HPV DNA was detected in 22% of samples from lesion sites and in 16% of samples from adjacent sites (p = 0.22) in patients with OL, in 24.5% and 22.4% of samples from lesion and adjacent sites, respectively, in patients with OLP (p = 0.40), and in 35.3% and 41.2% of samples from lesion and adjacent sites, respectively, in patients with OSCC (p = 0.36). Lesions adjacent to HPV-positive normal sites had an increased rate of HPV detection (OR = 30; 95% CI 9.57, 94.1). HPV-18 was the most frequent genotype, followed by HPV-6, -16, -33, and -53. HPV prevalence was reduced in lesions at keratinized sites (14.5%) compared with non-keratinized sites (34.4%; p = 0.007; OR = 0.32; 95% CI 0.13, 0.81). DISCUSSION In patients with OL, OLP, or OSCC, a high prevalence of HPV infection was shown in apparently normal sites adjacent to lesion sites infected by HPV. The lower HPV frequency in lesions at keratinized sites suggests that HPV detection by lesion brushing is affected by keratinization. The keratinized epithelium may be less susceptible to HPV infection or, alternatively, the highly proliferative activity in non-keratinized sites may predispose to HPV infection. CONCLUSION Results from this study indicate that taking samples from normal sites adjacent to oral lesions may be of value in HPV detection, particularly when the lesions are located at keratinized sites. This sampling procedure may allow more accurate diagnosis of HPV infection compared with sampling only the lesion site, and may also represent a reliable method to investigate the biological characteristics of HPV infection and related oral carcinogenesis.

Abstract
Surface metallization of SrTiO3(001) by hydrogen adsorption is experimentally confirmed for the first time by photoemission spectroscopy and surface conductivity measurements. The metallic state is assigned to a quantized state in the space-charge layer induced by electron doping from hydrogen atoms. The measured two-dimensional (2D) conductivity is well above the 2D Ioffe-Regel limit indicating that the system is in a metallic conduction regime. The mean free path of the surface electron is estimated to be several nanometers at room temperature.

Abstract
Avaliou-se a eficácia dos tratamentos, definidos pela International Embryo Transfer Society (IETS), de oócitos bovinos, maturados in vitro e expostos experimentalmente à Leptospira interrogans sorovar Grippotyphosa. Os oócitos foram obtidos por meio de punção folicular, selecionados e distribuídos em quatro grupos, expostos ao patógeno e submetidos aos diferentes tipos de tratamentos. Foram expostos à cepa na concentração de 4,7.10(5)/µL, virulenta e não adaptada ao meio de manutenção EMJH, e, de 6,3.10(5)/µL, avirulenta e adaptada ao meio, por 24 horas. Os grupos tratados com tripsina ou antibióticos apresentaram eficácia de 21,7%, e o grupo lavado sequencialmente 33,4%. Os tratamentos não foram eficazes para os contaminados com a cepa avirulenta. Concluiu-se que as normas de controle de qualidade estabelecidas pela IETS poderiam ser revisadas e, possivelmente, redefinidas, uma vez que a eficácia dos tratamentos, provavelmente, não depende somente da espécie do patógeno, pois há interferência da virulência e de ação dos tratamentos sobre o tipo de patógeno.

Abstract
We report 3C-SiC nano-crystals synthesis by thermal annealing of SiO2/Si wafers in CO2 gas. The nano-crystals have been characterized using scanning electron microscopy and atomic force microscopy. These results are correlated with selective area electron diffraction paterns, and transmission electron microscopy observations that evidence the formation of cubic SiC nano-crystals epitaxied on Si. In our experimental conditions, the crystals size is in the range 10-60 nm, increasing with the treatment time, as the crystals density. Using isotopic labelled SiO2 associated with Nuclear Reaction Analysis (NRA) and Nuclear Narrow Resonance Profiling (NRP), oxygen exchanges between CO2 and SiO2 could be evidenced.

Abstract
BACKGROUND The use of kidneys from older donors has become generally accepted and increasingly common, despite the knowledge that donor age is a well-known risk factor for graft failure. AIM To review our experience with the utilization of kidneys from donors older than 60 years. PATIENTS AND METHODS Among two hundred eight patients, 32 (group A) received an organ obtained from a donor older than 60 years. The organs were age-matched with a maximum gap of 20 years between donors and recipients. Organs from older donors were assigned to recipients presenting a body mass index lower than that of the donor. The primary end point was patient and graft survival. Secondary endpoints were incidences of delayed graft function and of acute rejection episodes as well as renal function at 3 months and yearly. RESULTS The two groups were comparable in terms of demographic features, indications for transplantation, comorbidities, as well as cold and warm ischemia times. The Mean lengths of follow up were 31.4 ± 20.3 months and 30.3 ± 20.1 months, respectively. Graft and patient survivals were comparable. Mean creatinine values at the study intervals were significantly lower among group B who received grafts from younger donors. The incidence of delayed graft function and acute rejection episodes were similar: 15.6% (5/32) versus 20.5% (36/176; P=0.35) and 15.6% (5/32) and 12.1% (21/167; P=0.136) in groups A and B, respectively. CONCLUSIONS Donor age older than 60 years showed a negative impact on kidney function. Though, given the escalating disparity between organ supply and demand, this precious source of organs cannot be neglected. We need better ways to use the available organs.

Abstract
The cryopreservation of bovine embryos has allowed an increase in their commercialization causing concern about the transmission of pathogens through the production and transfer of in vitro embryos. The International Society of Embryo Transfer (IETS) suggests the treatment of embryos with trypsin or antibiotics in alternating washes with culture medium in order to remove and/or inactivate infectious agents that may interfere with the final product. The aim of this study was to evaluate the effectiveness of trypsin treatment in the elimination and/or removal of bovine herpes virus type-1 (BoHV-1), Colorado strain, in murine embryos. Viral detection was made by n-PCR and cytopathic effect in Madin Darby bovine kidney (MDBK) cells. Six- to 8-wk-old female mice (Swiss) were superovulated and mated with fertile males of the same strain. After 24 h, the zygotes (n = 262) were divided into 3 groups: control group submitted to sequential wash (CSW), the group exposed to the virus (30 μL; 106.5 virus mL–1) and submitted to sequential wash (ESW), and the group exposed to the virus and submitted to the trypsin treatment (ETT). All the groups of zygotes and the last sequential wash drops were tested by nested-PCR and inoculated in MDBK cells to allow observation of cytopathic effects. All groups except for CSW showed positive results for the nested-PCR for both zygotes and for the last wash drops. A cytopathic effect was observed in all groups except for CSW, demonstrating the viability of the virus after treatment. These results demonstrated that trypsin treatment was not effective in eliminating or removal of BoHV-1. The need for such studies is fundamentally important when considering the potential risk of pathogen transmission by reproductive biotechnologies.

Abstract
The objective of regenerative medicine (RM) and Tissue Engineering (TE) is to create living functional tissues to repair or replace tissues or organ functions. This field holds the promise of regenerating damaged tissues and organs in the body. It has the potential to solve the problems of organ shortage and of toxicities deriving from life-long immunosuppression. In fact, cells in the regenerated organ would match those of the patient, from whom they would normally be derived. In the past decade, RM/TE has achieved striking results which are of interest to the transplant community. However, major roadblocks on the avenue to full success include the need for a deeper understanding of cell biology and of interactions with the extracellular matrix. We are presently not able to grow and expand cells indefinitely and safely in various scenarios where RM/TE may be indicated. The production of adequately vascularized scaffolds to optimize nutrients and oxygen delivery, assessment of the viability and function of the cells in the bioengineered construct, and the costs remain areas of scientific research.

Abstract
INTRODUCTION Antibiotic prophylaxis (AP) still represents a common but often misused procedure in dental practice, thus aggravating the risk for antimicrobial resistance and adverse effects occurrence. AIMS AND METHODS Our primary objective is to review the available scientific evidence regarding AP in dentistry both among healthy subjects and medically compromised patients. Additionally, the latest available guidelines provided by some of the most authoritative associations are here discussed. RESULTS AND CONCLUSIONS AP is advisable only in a small percentage of patients where a risk of severe infective complications (i.e. infective endocarditis and prosthetic joint infection, septicaemia in severely immuno-compromised patients, bisphosphonate-related osteonecrosis of the jaw) exists. On the contrary, little or no scientific evidence exists for AP in subjects with other systemic diseases as well as in healthy individuals. This pioneering recommendation is strongly evidence-based, since a consistent association between any dental procedure and the development of local and distant infective complications is still lacking. In addition, the daily bacteraemia secondary to routine habits has been thought to be robustly associated with a greater risk of systemic disease bacterial-related than a single dental procedure exposure. Compliance of general dental or family practitioners to the current recommendations seems not to be optimal, thus, efforts to improve it should be planned and undertaken.

Abstract
The aim of this study was to compare the plaque removal efficacy of a new oscillating/rotating/pulsating toothbrush [Oral-B Professional Care 8500 (PC 8500)] with two manual toothbrushes [Oral-B CrossAction Vitalizer (CAV) and Oral-B Indicator (IND), respectively]. The safety of the PC 8500 was also assessed. The study was a single-use, observer-masked, randomised 3 x 3 Latin square crossover design balanced for carryover effects. The enrolled subjects (n = 66) refrained from brushing for 23-25 h before each clinical examination. Plaque scores were recorded before and after brushing with the allocated toothbrush using the Turesky et al. modification of the Quigley and Hein plaque index. The safety was assessed evaluating the soft tissue conditions present after 30 days of the use of the PC 8500. The PC 8500 toothbrush was better in plaque removal efficacy compared with the CAV and IND brushes for full mouth and approximal surfaces (P < 0.01). When marginal surfaces were considered, the PC 8500 was significantly more effective than the IND (P < 0.01). No significant differences were found between PC 8500 and CAV (P > 0.05). The latter was shown to be significantly more effective than the IND at all tooth surfaces (P < 0.01). Safety examinations revealed the onset of only two small gingival abrasions after the 30-day use of the PC 8500. The PC 8500 toothbrush demonstrated to be more effective in plaque control than the CAV and IND in the full mouth and approximal surfaces and similar to the CAV in the marginal surfaces. The PC 8500 was safe to oral tissues in long-term use.

Abstract
Pseudomonas aeruginosa (PA) infections occurring after renal transplantation (RT) represent a potentially life-threatening complication. We present 2 cases of early death following RT in which PA was transmitted, possibly from the donor to the recipients, despite preoperative cultures that were negative. The donor had developed PA-related bilateral pneumonia while in the intensive care unit. However, after appropriate antibiotic therapy, no signs of infection were present at the time of organ retrieval and cultures were negative. Both recipients received a renal graft from the same donor and developed multi-drug resistant (MDR)-PA infections with bacterial phenotypes and resistances similar to the donor. The first recipient died 9 days after RT from rupture of a false aneurysm of the external iliac artery, caused by a fully thickened PA-related arteritis. The second recipient died postoperatively on day 10 after rupture of an aneurysm in the right vertebral artery. Our experience shows that MDR-PA infection early after RT may be a catastrophic event. Specific anti-PA antibiotic therapy in RT patients during the perioperative period is recommended in the case of PA infection in the donor, even after apparent successful therapy with negative cultures.

Abstract
A possible relationship between periodontal diseases (PDs) and cardiovascular diseases (CVDs) has been supposed and investigated. This review of the literature focuses exclusively on published studies on current theories and models of correlation between PDs and CVDs. A literature search of clinical and observational studies, in the English language, was performed in MEDLINE/PubMed, OVID database and Cochrane Oral Health Group's Trial Register. In addition, references cited in reviewed studies were evaluated for relevant papers. Various mechanisms are described in order to explain this possible association such as a hyper-responsive inflammatory response to chronic infections in predisposed individuals, and systemic effects of periodontal microorganisms including blood platelet aggregation, atheroma formation, increase in lipid levels, activation of acute phase reaction and systemic production of proinflammatory mediators, but a ultimate relation as well as the potential mechanisms have not been defined yet. Controversial result can be related to different method or objectives of studies including different study design, exposure evaluation, outcome variables and clinical endpoints considered. This paper provides a narrative review of the epidemiological studies dealing with the potential association between PDs and cardiovascular events. A precise association between PDs and CVDs, as well as the involved mechanisms are not yet well defined. Additional large-scale longitudinal epidemiological and intervention studies are necessary to validate this association.

Abstract
The aim of this study was to evaluate the efficiency of trypsin treatment on the inactivation of bovine herpesvirus type 1 (BoHV-1) on in vitro produced by fertilization and artificially infected bovine embryos. Bovine embryos on day 7 were exposed with 10 microl of BoHV-1, Los Angeles strain 10(7.5) TCID. These embryos and control embryos were divided in two groups: submitted to the sequential washes or to the trypsin treatment according to the International Embryo Transfer Society (IETS) guidelines. The embryos and the last washing drop of each group were used as inoculum to infect Madin Darby bovine kidney (MDBK) cells and submitted to nested PCR reaction using the primer that encodes the gene conserved region of virus glycoprotein gB. The data have shown that the control embryos and their last washing drop were negative. The exposed embryos that were treated with trypsin have shown positive results on the n-PCR and MDBK culture, and their last washing drop were negative. Our data have demonstrated that the trypsin treatment was not able to eliminate the BHV-1 of the embryos, suggesting an interaction between virus and embryo.

Abstract
BACKGROUND The side effects of chlorhexidine (CHX) have stimulated the search for alternative antiplaque agents such as amine fluoride/stannous fluoride (ASF) and essential oils (EO). The aim of the study was to investigate the plaque-inhibiting effects of two commercially available mouthrinses containing ASF and EO, respectively. METHODS The study was an observer-masked, randomized, 5 x 5 Latin square cross-over design, balanced for carryover effects, involving 15 volunteers in a 4-day plaque regrowth model. A 0.12% CHX rinse and a saline solution served as positive and negative controls, respectively. On day 1, subjects received professional prophylaxis, suspended oral hygiene measures, and commenced rinsing with their allocated rinses. On day 5, subjects were scored for disclosed plaque. The ASF rinse was tested at two dosages: 10 and 20 ml (ASF-10 and ASF-20, respectively). RESULTS The ASF and EO rinses showed a significant inhibition of plaque regrowth compared to saline (P <0.0001), but the lowest plaque indices were obtained with the CHX product (P <0.01). There were no significant differences among products containing ASF-10, ASF-20, and EO (P >0.05). There was no correlation between the occurrence of side effects and the use of a particular rinse product (P >0.2). CONCLUSIONS ASF and EO mouthrinses exerted effective and similar plaque inhibition. The two dosages tested for ASF did not differ in plaque reduction. These findings, together with those from long-term trials, suggest that ASF and EO rinses may represent effective alternatives to CHX rinse as adjuncts to oral hygiene.

Abstract
The aim of this paper was to provide an update on necrotizing periodontal disease (NPD). Original papers on this subject published in English from January 2002 until December 2007 were located in MEDLINE/PubMed database. Other sources were taken from the references of the selected papers. The clinical features of NPD include necrosis and ulceration of the gingival margin and the interdental papilla. These signs are usually associated to halitosis, pain, spontaneous gingival bleeding, malaise and sometimes fever. NPD usually occurs in developing countries, but few cases have also been reported in industrialized nations. The predisposing factors associated with the onset and progression of NPD include immunodeficiency, malnutrition, stress, smoking and poor oral hygiene. The treatment of NPD is dependent on the presence of pain and gingival necrosis. Systemic antibiotic therapy is recommended when a systemic disease is suspected.

Abstract
The present paper reviews relationship between chronic periodontitis and cardiovascular diseases. Original papers on this subject, published in English in the period between 2001 and the first semester 2006, were located in the MEDLINE/PubMed database. Additional studies were obtained by searching reference lists of previously published papers. Periodontal infection provides a chronic reservoir of inflammatory mediators and cytokines, lipopolysaccharide, which contribute to the formation of atheroma. Moreover, periodontal pathogens can penetrate the epithelial barrier of the periodontal tissues and reach the blood stream, carrying out a local atherogenic activity. Some studies indicated that periodontal treatment could result in reduction of cardiovascular events. If these results are confirmed in further intervention studies, the prevention and the treatment of periodontitis should be considered as factors able to avoid or reduced the onset and/or evolution of cardiovascular diseases.

Abstract
The liver is involved in up to 73% of patients suffering from hereditary hemorrhagic telangiectasia (HHT), but only some of them become symptomatic. Although management is often conservative, sometimes a more aggressive approach is required. The role of surgery is still undefined. Open ligation, banding, or closure of the arteriovenous malformation feeding artery have been proposed but rejected, as they are followed by an unacceptably high incidence of complications, derived from ischemia of the biliary tree. Orthotopic liver transplantation (OLT) has been successfully attempted in 28 patients with cardiac, biliary, or portal hypertension as well as mixed clinical presentations. Twenty-four were alive at time of data collection. Cardiovascular and pulmonary functions have improved after the operation in most cases. Intrahepatic relapse of the hallmark lesion of the disease (telangiectasia and arterovenous malformation) has been recently described in two cases. OLT represents a valuable therapeutic option for hepatic-based HHT, provided early diagnosis and referral to a specialized unit.

Abstract
BACKGROUND Chronic desquamative gingivitis (DG) is a condition characterized by erythema, ulceration, and desquamation of the free and attached gingiva, usually expression of a district-systemic disease, such as oral lichen planus (OLP). METHODS A combined protocol of oral hygiene and topic corticosteroid therapy was applied in 30 patients with DG associated with OLP. Plaque index (PI) and bleeding on probing (BoP) were evaluated at baseline and after 3 months. RESULTS PI scoring was significantly lower after treatment in anterior, posterior, and all sites (P < 0.0001) as well as in vestibular and lingual ones (P < 0.0001 and P = 0.0001, respectively). BoP measures were found to be reduced significantly to 22.94% in a full-mouth evaluation (P < 0.0001; OR = 2.633; 95% CI: 2.2685-3.0561) as well as in each specific site (P < 0.0001). CONCLUSION This clinical trial validated the efficacy, in patients with DG associated with OLP, of a protocol based on professional oral hygiene and self-performed plaque control measures in improving of gingival health status.

Abstract
We aimed to evaluate if in oral squamous cell carcinoma (OSCC) there is a relationship between histological grading (HG), TNM clinical stage and HPV infection; and to study the performance of fuzzy logic compared to traditional statistics, in the analysis of HPV status and correlates of OSCC. In cross-sectional analysis, the study group comprised 63 patients (mean age 68.89 years (SD +/-11.78), range (32-93); males 28 (44.4%), females 35 (55.6%)) with OSCC histologically diagnosed. HPV-DNA was studied in exfoliated oral epithelial cells by nested PCR (MY09/MY11 and GP5+/GP6+ primers). Data were analysed in parallel by traditional statistics with multivariate analysis and a fuzzy logic (FL) technique (membership functions as input, the ANFIS methodology, and the Sugeno's model of first order). HPV infection was detected in 24/63 (38.1%) of OSCC, as being HPV+ve 14/36 (38.9%) in G1, 7/18 (38.9%) in G2, and 3/9 (33.3%) in G3; HPV+ve 8/33 (24.2%) in Stage I, 9/12 (75.0%) in Stage II, 6/11(54.5%) in Stage III, and 1/7 (14.3%) in Stage IV. In both methods of analysis, no significantly increased risk of HPV infection was found for any HG score; whereas, TNM stage II was significantly associated to HPV infection (p=0.004; OR=9.375 (95% CI=2.030:43.30); OR'=11.148 (95% CI=1.951:43.30)), and, in particular, to primary tumour size T2 (p=0.0036; OR=7.812 (95% CI=1.914:31.890); OR'=9.414 (95% CI=1.846:48.013)); FL (% of prevision: 79.8; Root Mean-Square Error (RMSE): 0.29). No association was found between HPV infection and any demographical variable. Our findings show an association between HPV infection with TNM (stage II-T2), but not with histological grading of OSCC. Also, FL seems to be an additional effective tool in analysing the relationship of HPV infection with correlates of OSCC.

Abstract
BACKGROUND Due to the side effects of chlorhexidine digluconate (CHX) mouthrinsing, a spray has been proposed as an alternative method of CHX delivery to the oral cavity. The aim of this study was to investigate the plaque inhibitory effects of CHX, cetylpyridinium chloride (CPC), and triclosan (TRN) delivered by sprays and mouthrinses. METHODS The study was an observer-masked, randomized cross-over design balanced for carryover effects, involving 15 healthy volunteers in a 4-day plaque regrowth model. Products being tested (0.2% CHX, 0.12% CHX, 0.05% CPC, and 0.03% TRN) were used both as sprays and mouthrinses. A saline solution served as a negative control. On day 1, subjects received professional prophylaxis, suspended oral hygiene measures, and commenced using their allocated products. On day 5, subjects were scored for disclosed plaque. RESULTS CHX sprays (P<0.01) were the most effective sprays in preventing plaque regrowth, without significant differences between the two concentrations tested (P>0.05). TRN spray showed a significant inhibition of plaque regrowth in comparison to the negative control (P<0.05). CPC spray did not differ from saline spray (P>0.05). A similar trend of efficacy was detected for rinses. Although the effect on plaque regrowth observed with CHX rinses was superior to that of CHX sprays (P<0.0003), the latter did not cause side effects (P>0.2). CONCLUSIONS These findings, together with those from clinical trials, suggest that the CHX-containing sprays may represent an effective alternative to CHX rinses when mechanical oral hygiene has to be avoided in restricted areas. On the contrary, the TRN and CPC sprays showed little or no plaque inhibitory effects.

Abstract
Urologic complications in kidney transplantation have an incidence ranging from 3% to 20%, representing an important cause of organ loss. From January 2001 to September 2004, 123 renal transplantations were performed using an immunosuppressive protocol including basiliximab, mycophenolate mofetil, calcineurin inhibitors, and steroids. The surgical technique was vascular anastomoses to external iliac vessels, and ureteral anastomosis according to Lich Gregoire technique using a JJ ureteral stent. We report 5 renal complications (4.2%) and 4 extrarenal complications (3.5%), the majority of which required corrective surgery. The surgical strategy uses the clinical condition of the donor and the recipient; the anatomic anomalies of the graft, and a reduced cold ischemia time. Moreover, a reduction in acute rejection episodes and immediate renal function has been fundamental to reduce urologic complications. In fact, the main cause of urologic complications is ureteral ischemia, linked both to backtable surgery and to rejection episodes. Another important factor in the reduction of early urologic complications has been the routine use of a JJ stent, which allowed us a conservative approach in this setting.

Abstract
The most effective treatment of end-stage renal disease is renal transplantation; its superiority to prolong the longevity of patients is well established. Patient and graft survivals have improved with more potent immunosuppression but this advance has been associated with an increased incidence of cancer. The aim of this study was to assess the prevalence of cancer among 265 kidney transplant recipients engrafted between 1968 and October 2004. The overall prevalence of de novo malignancies was 3%. The mean age at diagnosis was 53.3 years (range, 28-63 years) and the duration of the transplant was 11.6 years (range, 0.3-33 years). One patient among 127 (0.8%) who had a history of less than 3 years under immunosuppression, developed a posttransplantation lymphoproliferative disorder (PTLD). Among the 138 patients who had more than 3 years immunosuppression, 7 (5%) developed neoplasms of vulva, colon, native kidneys, prostatic gland, and ovary. One patient was affected by de novo carcinoma in the transplanted kidney. Compared with other published studies, our early cancer prevalence is low, possibly due to a careful history before grafting, good HLA matching, and abstinence from anti-T-cell therapy for treatment of acute rejection episodes. The low level of immunosuppression may account for the low prevalence of neoplasia. The risk of developing a malignancy increases with long-term immunosuppression, comparable with most reports.
