Abstract
OBJECTIVE To compare the effectiviness of spiramycin/cotrimoxazole (Sp/C) versus pyrimethamine/sulfonamide (Pyr/Sul) and spiramycin alone (Spy) on mother-to-child transmission of toxoplasmosis infection in pregnancy. STUDY DESIGN Retrospective study of pregnant women evaluated for suspected toxoplasmosis between 1992 and 2011. RESULT A total of 120 mothers and their 123 newborns were included. Prenatal treatment consisted of spiramycin in 43 mothers (35%), spiramycin/cotrimoxazole in 70 (56.9%) and pyrimethamine/sulfonamide in 10 (8.1%). A trend toward reduction in toxoplasmosis transmission was found when Sp/C was compared with Pyr/Sul and particularly with Spy alone (P=0.014). In particular, Spy increased the risk of congenital infection when compared with Sp/C (odds ratio (OR) 4.368; 95% CI: 1.253 to 15.219), but there was no significant reduction when Sp/C was compared with Pyr/Sul (OR 1.83; 95% CI: 0.184 to 18.274). CONCLUSION The treatment based on Sp/C has significant efficacy in reducing maternal-fetal transmission of Toxoplasma gondii when compared with Pyr/Sul and particularly to Spy. Randomized controlled trials would be required.

Abstract
BACKGROUND The aim of this study was to determine the ability of two feed additives, a fumarate-malate (FM) and a polyphenol-essential oil mixture (PM), in attenuating the drop of ruminal pH and the metabolic and immune response resulting from an excessively high grain diet. Six heifers were used in a 3 × 3 Latin square experiment and fed a low starch (LS) diet for 14 d, followed by a high starch (HS) diet for 8 d (NDF 33.6%, starch 30.0% DM). In the last 5 days of each period, barley meal was added to decrease rumen pH. During HS feeding all animals were randomly assigned to one of the following three dietary treatments: no supplement/control (CT), a daily dose of 60 g/d of FM, or 100 g/d of PM. Reticular pH was continuously recorded using wireless boluses. On d 21 of each period, rumen fluid was collected by rumenocentesis (1400 h), together with blood (0800 h) and fecal samples (0800, 1400, and 2100 h). RESULTS The correlation coefficient of pH values obtained using the boluses and rumenocentesis was 0.83. Compared with CT and PM, the FM treatment led to a lower DMI. Nadir pH was lowest during CT (5.40, 5.69, and 5.62 for CT, FM and PM, respectively), confirming the effectiveness of both supplements in reducing the pH drop caused by high grain feeding. This result was confirmed by the highest average time spent daily below 5.6 pH (199, 16 and 18 min/d) and by the highest acetate to propionate ratio of the CT fed heifers. The PM decreased the concentrations of neutrophils (2.9, 3.2, and 2.8 10(9)/L) and acute phase proteins: SAA (37.1, 28.6 and 20.1 μg/mL), LBP (4.1, 3.8, and 2.9 μg/mL), and Hp (675, 695 and 601 μg/mL). Free lipopolysaccharides (LPS) were detected in blood and feces, but their concentrations were not affected by treatments, as the remaining blood variables. CONCLUSIONS Data suggest that both additives could be useful in attenuating the effects of excessive grain feeding on rumen pH, but the PM supplement was more effective than FM in reducing the inflammatory response compared to CT.

Abstract
AIM The aim of the study was to evaluate expression of CD10 in a series of gastrointestinal tumors (GIST) and to find its relationship with prognosis, biological and clinical behavior. GISTs represent the most frequent gastrointestinal (GI) mesenchymal tumors. Biological behavior of GIST cannot be easily predicted; for this reason many biomolecular factors are being investigated to predict prognosis. Recently the role of the CD10 as prognostic predictor in the carcinogenesis of the gastrointestinal carcinomas has been accurately studied. To our knowledge, no data regarding the role of CD10 in GISTs have been published to date. METHODS CD10 expression was searched by immunohistochemistry in 29 histological specimens of proved GIST surgically treated. Patients' characteristics and all pathologic features of tumors were statistically reviewed and compared to CD10 expression. Survival analysis was also calculated respect to CD10 expression and relevant clinical or pathological features. RESULTS CD10 was expressed in 24.1% of cases. There was no correlation between CD10 positivity and risk category, morphology, size or mitosis. The CD10 expression status did not prove to be statistically related to worse prognosis, advanced disease (metastasis) or recurrence, however it was significantly correlated to the tumor site. CONCLUSION CD10 expression in our series seems to be associated to a small bowel origin of tumor. CD10 expression alone failed to reveal a statistically significant prognostic value. However survival analysis revealed worse prognosis in stomach tumours with mitotic count >10/50 HPF.

Abstract
BACKGROUND The onset of a sprue-like enteropathy in association with olmesartan therapy has been recently reported. AIMS To perform a systematic review of the literature and describe three additional cases of olmesartan-associated enteropathy. METHODS Electronic and manual bibliographic searches were performed to identify original reports in which subjects who were undertaking olmesartan developed a sprue-like enteropathy. Because of the scarcity of studies with adequate sample size, case series with less than 10 patients and case reports were also considered. Data extraction was performed independently by two reviewers. RESULTS A total of 11 publications met our pre-defined inclusion criteria, for an overall number of 54 patients (including our series). Almost all patients presented with diarrhoea and weight loss. Normocytic normochromic anaemia and hypoalbuminaemia were the commonest laboratory defects at presentation. Antibody testing for coeliac disease was always negative. Variable degrees of duodenal villous atrophy were present in 98% of patients, while increased intra-epithelial lymphocytes were documented in only 65% of cases. After discontinuation of olmesartan, all reported patients achieved resolution of signs and symptoms. CONCLUSIONS Although the available evidence is limited, the olmesartan-associated sprue-like enteropathy may be considered as a distinct clinical entity, and should be included in the differential diagnosis when serological testing for coeliac disease is negative.

Abstract
The aim of this study was to assess the effects of space allowance (4.5 m(2)/head vs. 9 m(2)/head) on the behaviour of shelter dogs (Canis familiaris) at different times of the day (from 10:30 to 13:30 vs. from 14:30 to 17:30), and the dogs' preference between two types of beds (fabric bed vs. plastic basket). Twelve neutered dogs (seven males and five females aged 3-8 years) housed in pairs were observed using a scan sampling recording method every 20 s for a total of 14,592 scans/treatment. An increase in space allowance increased general level of activity (risk ratio (RR)=1.34), standing (RR=1.37), positive social interactions (RR=2.14), visual exploration of the environment (RR=1.21), and vocalisations (RR=2.35). Dogs spent more time in the sitting (RR=1.39) or standing (RR=1.88) posture, in positive interactions (RR=1.85), and active visual exploration (RR=1.99) during the morning than in the afternoon. The dogs were more often observed in the fabric bed than in the plastic basket (53% vs. 15% of total scans, p<0.001). Results suggest that a 9.0 m(2)/head space allowance could be more beneficial to dogs than one of 4.5 m(2).

Abstract
Pancreaticoduodenectomy is the standard care for invasive ampullary adenocarcinomas. However, endoscopic snare papillectomy (ESP) might play a curative role in very selected patients. We studied a series of 15 patients with T1 ampullary adenocarcinoma who were treated by ESP alone and followed up for a mean of 29.6 ± 21.9 months (range 8 - 81 months). ESP was curative for eight patients (57.1 %). No tumor-related death was observed in patients with a cancer infiltration depth of ≤ 4 mm. According to this preliminary experience, we suggest that this measurable variable threshold should be considered as a possible basis for future large-scale studies.

Abstract
Failure to respond to commercial limited antigen diets can occur in dogs kept on a dietary trial for the diagnosis of adverse food reaction (AFR). The aim of this study was to assess twelve canine dry limited antigen diets (eleven novel protein diets and one hydrolysed diet) for potential contamination by ingredients of animal origin not mentioned on the label. The validity of the two methods adopted for the detection of such food antigens was also evaluated. Each dietary product was analysed by microscopy analysis using the official method described in Commission Regulation EC 152/2009 with the aim of identifying bone fragments of different zoological classes (mammalian, avian and fish) and by polymerase chain reaction (PCR) for the identification of DNA of animal origin. Discrepancies between the results obtained by PCR and/or microscopy analysis and the ingredients listed on pet food packages were found. Only in two pet foods did the results of both analyses match the ingredients listed on the label. In the remaining ten samples, microscopy detected bone fragments from one or two unpredicted zoological classes, revealing avian fragments in six of ten samples followed by those of fish in five of ten and mammalian fragments in four of ten. In two samples, microscopy analysis identified a contamination that would have otherwise passed unobserved if only PCR had been used. However, PCR confirmed the presence of all the zoological classes detected by microscopy and also identified the DNA of an additional unexpected zoological class in two samples. Dogs might fail to respond to commercial limited antigen diets because such diets are contaminated with potential allergens. Both PCR and microscopy analysis are required to guarantee the absence of undeclared animal sources in pet foods. Before ruling out AFR, a novel protein home-made diet should be considered if the dog is unresponsive to a commercial regimen.

Abstract
BACKGROUND Few studies show the detrimental effect of canine obesity on cardiopulmonary function (CPF). The 6-Minute Walk Test (6MWT) is a noninvasive exercise test easy to perform in clinical settings. OBJECTIVE The aim of this study was to investigate the effect of obesity and body weight loss (BWL) on CPF assessed by the 6MWT and arterial blood gas analysis. ANIMALS Six experimental Beagles and 9 privately owned obese dogs were enrolled in a diet-induced BWL program. METHODS Arterial blood gas analysis and 6MWT were repeated in obese subjects (BCS 8-9/9), in the middle of BWL (overweight, BCS 6-7/9), and in lean dogs (BCS 5/9). Heart rate (HRp) and oxygen saturation (SpO2 ) were measured by pulse oximetry before the 6MWT, at midtest, and during a 5-minute recovery period. RESULTS Twelve dogs completed the BWL program (initial BW, 27.3 ± 2.9 kg; final BW, 20.85 ± 2.9, lsmeans ± SE, P ≤ .001). BWL caused a significant increase in 6MWT walked distance (WD; obese: 509 ± 35 m; overweight: 575 ± 36 m; lean: 589 ± 36 m; P ≤ .05). Resting arterial blood gas results were not influenced by BWL. Including all time points, obese dogs showed higher HRp and lower SpO2 compared to overweight and lean dogs. SpO2 at the end of the walk was significantly lower in obese dogs. CONCLUSION AND CLINICAL IMPORTANCE Obesity negatively affects 6MWT performances in dogs. The 6MWT may be used to demonstrate the efficacy of BWL to improve CPF and quality of life in obese dogs. Although BWL induced significant improvement of cardiopulmonary parameters before ideal BW, WD improved until the end of the BWL program.

Abstract
Solitary fibrous tumors are very rare neoplasms that seldomly appear in extra-serosal soft tissues. In such cases, an accurate preoperative diagnosis is often difficult and challenging, especially in extrapleural ones. Traditionally, extrapleural solitary fibrous tumours have been regarded as indolent neoplasms similar to their intra-thoracic counterparts, although there has been some evidence that this subgroup could be a subset of more aggressive malignant tumours. For these reasons, surgical excision is mandatory and represents, to date, the best therapeutic option. In this article we report a case of a malignant solitary fibrous tumor of the chest wall in a 58-year-old man. Problems related to differential diagnosis and the possible pitfalls that can be encountered in the diagnostic process of such rare tumors are discussed.

Abstract
Background: Patients with breast cancer frequently develop bone metastases, which are responsible for high morbidity and mortality. It is known that numerous molecules are involved in the bone metastasization process and that only cancer cells with a specific molecular profile are capable of reaching and colonizing bone tissue. The early detection of patients with a high probability of relapsing to bone could be used to select candidates for tailored therapy with bone-specific drugs such as bisphosphonates or RANK-L inhibitors. The aim of the present study was to identify a pattern of tissue markers from primary breast cancer capable of predicting bone metastatization.
Material and methods: The expression of different markers was retrospectively analyzed in frozen breast cancer tissue samples from 40 patients comprising 15 cases with no evidence of disease (NEDP), 15 with bone metastases (BMP), and 10 with visceral metastases (VMP). Twelve transcripts were analyzed by Quantitative Real time PCR: trefoil factor 1(TFF1), DKK1, bone sialoprotein (IBSP), heparanase (HPSE), osteopontin (SPP1), Agr2, SPARC, CTGF, COMP, follistatin (FST), osteoprotegerin and RANK. The predictive accuracy of each marker was calculated using receiver operating characteristic (ROC) curves.
Results: Analysis of marker expression in the 3 different subgroups showed twofold higher median values of COMP and HPSE in BMP with respect to either NEDP or VMP (no significant difference). Furthermore, TFF1 median value was about sevenfold higher in BMP than in the other 2 subgroups (p=0.05). The area under the curve (AUC) was 0.73 for TFF1 and 0.62 for COMP and HPSE. Considering markers as dichotomous variables, TFF1 expression in BMP reached 67% compared to 21% and 20% in NEDP and VMP, respectively. In dichotomous variable analysis, the most important result was observed for TFF1; in particular, TFF1 positivity was observed in 67% of cases in the BMP subgroup compared to only 21% and 20% in NEDP and VMP, respectively. The combination analysis of TFF1 and other markers showed that positivity to at least one of the three markers, TFF1, DKK1, or IBSP, was observed in 80% of cases for the BMP group, and in only in 21% and 20% of cases in NEDP and VMP subgroups (p=0.041). Another interesting marker was RANK: although sensitivity was fairly low (12%), specificity reached 100% in both control groups.
Conclusions: Our preliminary study identified a RT-PCR gene expression pattern in primary breast cancer that could predict patients destined to bone relapse. Such patients could consequently benefit from adjuvant treatment with bone-targeted therapy.

Abstract
BACKGROUND AND STUDY AIMS Lymphoepithelial cyst of the pancreas (LCP) is a rare, benign cyst mimicking pseudocyst or cystic neoplasm. Literature describing LCP is limited to case or brief series reports, and the natural history of this condition is largely unknown. A literature review was carried out in order to elucidate the clinical, pathological and biochemical features of LCP. The aim of this study was to define diagnostic criteria and treatment. METHODS A Medline and Pubmed search was conducted by using the key-words "lymphoepithelial cyst" and "pancreas". The articles found were accurately examined and all details regarding clinical and pathological features were included in a data-base. Furthermore, a case recently observed in our unit was added to the review. RESULTS Ninety-two cases of LCP were found in the worldwide literature, including the case that we observed. LCP occurs more frequently in males (M:F=5.5:1), its preferred site is the tail of the pancreas, and its size ranges between 2 and 10centimetres. Histologically, it is a true cyst delineated by a keratinizing squamous epithelium surrounded by lymphoid tissue. LCP is asymptomatic in the majority of cases and preoperative diagnosis is complicated by a lack of specific radiological features of the disease. An accurate preoperative diagnosis can only be made by obtaining cytological specimens and placing them in the hands of a pathologist who is familiar with the cytological appearances of the disease. CONCLUSIONS LCP is a rare lesion worldwide, without any prevalence in different countries or in different ethnic groups. Understanding the features of LCP, making an accurate diagnosis and differentiating it from cystic neoplasm preoperatively is vital, as when it is diagnosed certainly, a conservative treatment is justified. Otherwise, radical surgery in the form of pancreatic resection is required to exclude the diagnosis of pancreatic cystic neoplasm.

Abstract
Leptin and adiponectin are adipokines produced by the white adipose tissue. The adipokines have been shown to be valuable quantitative markers of adiposity in dogs. Leptin positively correlates with body condition score (BCS) in dogs, regardless of age, sex and breed, and is influenced by feeding state, pharmacological treatment and thyroid gland activity. Conversely, adiponectin negatively correlates with body fat mass and is therefore more abundant in lean animals. The implication of leptin and adiponectin in the pathogenesis of metabolic syndrome is well established in humans, but currently lacking in dogs. Additional studies are necessary to demonstrate their potential usefulness for monitoring the progression of obesity-related diseases and response to treatment. To date, measurement of canine leptin and adiponectin has been used in experimental studies only, whereas bodyweight and BCS are considered the first-approach parameters for the routine assessment of body fat content in obese dogs.

Abstract
Abstract
Background: The RANK/RANKL/OPG axis plays an important role in the bone metastasization process. CXCL12 is overexpressed in bone and, like its receptor, CXCR4, is a determinant of organ tropism. The objective of the present study was to evaluate whether the expression of these markers in primary breast cancer can predict the onset of bone metastases. Methods: Marker expression was evaluated by immunohistochemical staining in paraffin-embedded sections of primary breast cancers from 40 individuals: 10 patients (median age 64 years, range 48-78) showed no evidence of disease (NED — control group) at a median of 9.8 (range 6.9-11.5) years, while 30 (median age 67 years, range 42-87) had relapsed. In the latter group, 10 (median age 66 years, range 42-87) had visceral metastases (VM — control group) and 20 (median age 69 years, range 42-87) had bone metastases (BM — case group), both confirmed radiologically. The 3 patient subgroups (NED, visceral lesions, bone lesions) were matched for age classes (≥60 years, > 60 years). The study design was reviewed and approved by the local ethics committee.
Results: In the overall series, 17.5% of tumors were positive for RANK, 22.5% for OPG and 25% for CXCR4. None of the patients expressed RANKL. RANK and OPG resulted equally expressed in 20% of NED patients, while CXCR4 was expressed in only 10% of this group. OPG was expressed in 20% of VM patients, whereas RANK or CXCR4 were not detected. RANK and OPG positivity was present in 25% of BM patients, while CXCR4 was expressed in 45% of cases. CXCR4 was the only marker with a significantly higher frequency of expression in bone metastases than in visceral lesions (p=0.013). Taking into consideration all the patients without bone involvement (NED plus VM patients), it was observed that CXCR4 expression, alone and in combination with RANK, significantly discriminated between BM patients and the control group (p=0.008 and P<0.001, respectively). ER-positivity and HER2-negative status were observed in 80% and 95% of BM patients, respectively, but neither discriminated between cases and controls. Conclusions: In our study, ER-positivity and HER2- negativity identified a high percentage of bone relapse patients, but also highlighted patients who did not have bone involvement. RANK and CXCR4 expression, on the other hand, would appear to be a more accurate predictor of bone relapse. Such evidence could help to identify patients with a high probability of developing bone metastases, which can be treated with bisphosphonates or other bone-targeted therapies, such as denosumab, in an attempt to prevent distant metastases. Our results are currently being validated in a larger series of breast cancer patients.

Abstract
The electron-positron collider DAPhiNE, the Italian Phi factory, has been recently upgraded in order to implement an innovative collision scheme based on large crossing angle, small beam sizes at the crossing point, and compensation of beam-beam interaction by means of sextupole pairs creating a "crab-waist" configuration in the interaction region. Experimental tests of the novel scheme exhibited an increase by a factor of 3 in the peak luminosity of the collider with respect to the performances reached before the upgrade. In this Letter we present the new collision scheme, discuss its advantages, describe the hardware modifications realized for the upgrade, and report the results of the experimental tests carried out during commissioning of the machine in the new configuration and standard operation for the users.

Abstract
Abstract
Background: Over 50% of breast cancer patients who relapse systemically develop bone metastases. The RANK/RANKL/OPG axis governs osteoclastogenesis and bone reabsorption. In particular, osteoprotegerin (OPG) is a decoy receptor of RANK-L (receptor activator of nuclear factor kappa B ligand) and seems to prevent bone destruction by blocking the binding of RANKL with its receptor. We studied the efficacy of circulating OPG compared to the traditional markers CEA and CA15-3 for the early detection of bone lesions.Methods: The study was carried out on peripheral blood from 72 patients with breast cancer, of whom 33 were disease-free and 39 had bone metastases. The OPG transcript was determined using quantitative PCR analysis, and the traditional markers were quantified by immunoenzymatic assays.Results: The OPG median value was higher in disease-free patients (median = 1.7, 0.4-8.9) than in bone-relapse patients (median = 0.6, 0.1-5.2) (p<0.001). CEA and CA15-3 median values were 1.3 (0.0-8.3) ng/ml and 10.6 (0-45.7) U/ml, respectively, in disease-free patients and 4.8 (0.0-90.6) ng/ml and 69.8 (7-1538) U/ml, respectively, in patients with bone metastases (p< 0.0001 for both markers). Considering 0.9 as cut off of OPG relative expression, our analyses revealed a specificity of 88% with respect to 97% for CEA and 94% for CA15-3. OPG sensitivity was 73% compared to only 49% for CEA and 67% for CA15-3. When OPG was considered in combination with the traditional markers, sensitivity increased from 49% to 83% for CEA and from 67% to 88% for CA15.3.Conclusions: Our results on a preliminary series of breast cancer patients indicate that the bone turnover marker OPG greatly increases CEA and CA15-3 sensitivity in predicting bone metastases.

Abstract
We report the results of a series of underwater imaging experiments in the visible, carried out at ENEA (Frascati, Rome) by using a bistatic, amplitude-modulated laser optical radar system. In these experiments, polarimetry is used for minimizing the water backscattering signal and improving the accuracy of phase measurements directly related to distance. The presented technique enables one to obtain 3D images of underwater real scenes characterized by high quality, space resolution, and contrast. The results are of remarkable importance for applications in the 3D imaging of submerged objects, such as submarine archaeological sites.

Abstract
e22000 Background: Breast cancer is the most frequent tumor in women. About 80% of patients with metastatic disease present bone involvement, in which the OPG/RANKL/RANK system would seem to play an important role. Our aim was to evaluate the potential usefulness of OPG bone marker for the early diagnosis of bone metastases. Methods: The study was carried out on 120 individuals: 30 healthy donors, with a median age of 40 years (21–76) and 90 breast cancer patients, with a median age of 57 years (30–86). Among patients, 49 were disease-free (median age 52 years) and 41 were at first diagnosis of bone metastases (median age 63 years). OPG transcript was determined in peripheral blood samples using quantitative PCR analysis. A receiver operating characteristic (ROC) curve was used to calculate the diagnostic accuracy of the marker. Results: OPG values were not correlated with age in any of the subgroups. The OPG median value was not statistically different in healthy donors (median=1.9; range 0.6–4.7) and disease-free patients (median=1.7; range 0.4–8.9), whereas it was threefold higher than that observed in relapsed patients (median=0.6; range 0.1–5.2; p<0.001), regardless of the number of metastatic sites. The area under the curve (AUC) in disease-free patients was 0.82 for OPG, with 71% sensitivity and 88% specificity, using a cut off ≤ 0.8. In a parallel analysis of 37 patients (14 disease-free and 23 with bone metastases) for whom CEA and CA15.3 information was available, specificity for each marker was 100%, whereas sensitivity was only 61% and 59%, respectively. When these markers were considered in combination with OPG, an increase in sensitivity, albeit not statistically significant, was observed for CEA (83%) and CA15.3 (82%). Conclusions: Our preliminary data show a potential role of the OPG bone turnover marker for the early diagnosis of bone metastases. Results now need to be confirmed in a larger case series. No significant financial relationships to disclose.

BACKGROUND An excess of intracellular beta-catenin protein is triggered by various genetic alterations in melanoma cell lines, and has been suggested to play a role in melanoma tumorigenesis. OBJECTIVES To investigate the role played in vivo by beta-catenin in melanoma tumorigenesis, we compared the cytoplasmic detection of beta-catenin in benign melanocytic cells vs. malignant melanoma cells presumably generated from these benign melanocytic cells. For this purpose, melanocytic naevi occurring in association with melanoma, which were suggested to be melanoma precursors, were compared with their associated melanoma for beta-catenin cytoplasmic immunoreactivity. METHODS Fifty-seven consecutive cases of primary cutaneous melanoma were considered, and 15 of them were found to be associated with a melanocytic naevus portion. The naevus portion showed features of acquired melanocytic naevus (total 12 cases: five dysplastic, seven intradermal) or congenital growth pattern naevus (total three cases: one superficial, two deep). All specimens were immunohistochemically investigated for beta-catenin. RESULTS Virtually all primary cutaneous melanomas, including those associated with a naevus portion, showed cytoplasmic beta-catenin positivity. However, the intradermal naevus portion was consistently cytoplasmic beta-catenin negative, while both the dysplastic and the congenital naevus portions were cytoplasmic beta-catenin positive. CONCLUSIONS Beta-catenin excess may play a role in melanoma tumorigenesis, because beta-catenin cytoplasmic reactivity was found in primary cutaneous melanoma but not in its associated intradermal naevus precursor. As, however, beta-catenin cytoplasmic reactivity was detected not only in primary cutaneous melanoma but also in its associated dysplastic/congenital naevus precursors, beta-catenin stabilization alone is not sufficient to play a decisive role for melanoma onset.
