Abstract
The MuCool Test Area (MTA) at Fermilab is a facility to develop the technology required for ionization cooling for a future Muon Collider and∕or Neutrino Factory. As part of this research program, feasibility studies of various types of RF cavities in a high magnetic field environment are in progress. As a unique approach, we have tested a RF cavity filled with a high pressure hydrogen gas with a 400 MeV proton beam in an external magnetic field (B = 3 T). Quantitative information about the number of protons passing through this cavity is an essential requirement of the beam test. The MTA is a flammable gas (hydrogen) hazard zone. Due to safety reasons, no active (energized) beam diagnostic instrument can be used. Moreover, when the magnetic field is on, current transformers (toroids) used for beam intensity measurements do not work due to the saturation of the ferrite material of the transformer. Based on these requirements, we have developed a passive beam diagnostic instrumentation using a combination of a Chromox-6 scintillation screen and CCD camera. This paper describes details of the beam profile and position obtained from the CCD image with B = 0 T and B = 3 T, and for high and low intensity proton beams. A comparison is made with beam size obtained from multi-wires detector. Beam transmission efficiency through a collimator with a 4 mm diameter hole is measured by the toroids and CCD image of the scintillation screen. Results show that the transmission efficiency estimated from the CCD image is consistent with the toroid measurement, which enables us to monitor the beam transmission efficiency even in a high magnetic field environment.

Abstract
134 Background: In this prospective study, in patients with CRPC previously treated with docetaxel, we evaluated prostate specific antigen (PSA) and FCH-PET/CT for early response assessment to abiraterone acetate, and assessed frequency of early FCH-PET/CT discordant with PSA and clinical response. Methods: Twenty nine metastatic CRPC pts progressing after docetaxel chemotherapy received abiraterone acetate 1,000 mg daily with prednisone 5 mg twice daily in continuous 28-day cycles. Patients were evaluated monthly for serological PSA response and safety. FCH-PET/CT was repeated after 4-6 weeks and a CT scan was done after 3 months of abiraterone acetate. FCH-PET/CT bone flare was defined as the combination, after 3 months of therapy, of an interpreting radiologist’s report indicating progressive disease (PD) in context of a ≥50% decline in PSA, no PD at 3-month CT scan, with FCH-PET/CT improvement or stability 2-3 months later. Results: Three of 29 patients treated with abiraterone acetate did not perform the follow-up FCH-PET/CT due to rapidly PD with a decline in performance status. Of the remaining 26 patients, 4 are still undergoing early response evaluation. Twenty two pts, median age was 71 yrs (range, 57-86 yrs) were evaluable for this analysis. A ≥50% PSA decline was observed in 15/22 (68%) evaluable pts. Undetectable PSA levels (≤0.1 ng/mL) occurred in one case. Early FCH PET/CT response assessment was as follows: complete response (n=2, 9%), partial response (n=7, 32%), stable disease (n=3, 14%), PD (n=10, 45%), but in 4 of 10 pts with PD a bone flare phenomenon on FCH PET/CT was observed. PSA decline ≥50% and FCH PET/CT response correlated in 19 of 22 pts (86%). Conclusions: Discordant findings between serologic PSA response and increases in early FCH-PET/CT bone lesion intensity are reported here for the first time in CRPC. Further investigation is needed to clarify the confounding effect of FCH-PET/CT bone flare on patient management and interpretation of results.

Abstract
PURPOSE Talc pleurodesis (TP) is employed worldwide for the management of persistent pneumothorax or pleural effusion, particularly of malignant origin. However, there are very little available data on (18)F-fluorodeoxyglucose positron-emission tomography/computed tomography ((18)F FDG PET/CT) response evaluation in malignant pleural mesothelioma (MPM) patients treated with TP and chemotherapy. METHODS Patients with histologically confirmed MPM underwent TP and FDG PET/CT staging and restaging after 3-4 courses of chemotherapy. All patients fasted and received a dose of 5.18 MBq (18)F-FDG per kilogram of body weight. Whole-body emission scans were acquired with and without Ordered Subset Expectation Maximization (OSEM) iterative reconstruction algorithm. RESULTS From January 2004 to March 2010, 8 patients with biopsy confirmed MPM (7 epithelial, 1 biphasic), with a median age of 65 years (range: 54-77), were evaluated. Median follow-up was 31 months (range: 4-44). After TP treatment, there was a mean interval of 14 days (range: 9-22) and 125 days (range: 76-162) between FDG PET/CT staging and restaging. According to modified RECIST and EORTC criteria, there was a concordance between the radiologic and metabolic SUVmean and SUVmax responses in 6 (75%) and 3 (37.5%) patients, respectively. CONCLUSION TP produces an increased FDG PET uptake which may interfere with the post-chemotherapy disease evaluation. In our case series, the metabolic response measured by SUVmean seems to be in better agreement with the radiologic response compared to the SUVmax.

Abstract
Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor with generally disappointing results in terms of survival, however, there are occasional long-term survivors probably due to the biologic characteristics of the disease. Standard uptake value (SUV) of [18F] Fluorodeoxyglucose (FDG) evaluated by photon emission tomography (PET) is now widely accepted as an indicator of biologic behavior in several malignancies. The aim of this study was to verify whether SUVmax and SUVmean are inversely associated with the prognosis of patients with MPM and whether there was a correlation between grading/disease stage and SUV value. Patients with histologically proven MPM underwent integrated PET and computed tomography (CT) scanning. Patients fasted and received 5.18 MBq of FDG per kilogram of body weight. Based on the maximum Chi-Square method, a SUVmax of 4.21 (range: 2.30–14.74) and a SUVmean of 2.78 (range: 1.80–7.00) were used to classify patients as having a good or poor prognosis, respectively. From January 2004 to March 2010, 27 patients were analyzed: median age was 65 years (range: 54–77) and histologic MPM subtypes were epithelioid (23 patients) and biphasic (4 patients). At a median follow-up of 23 months (range: 1–52), there was no difference in median survival for either high or low SUVmax [26 months (range: 11-not reached) vs.19 months (range: 12-not reached); p = 0.811] or for high or low SUVmean [26 months (range: 8-not reached) vs.19 months (range: 11-not reached); p = 0.831]. High SUVmax (p = 0.018) was statistically correlated with high-stage disease. There was only a trend towards statistical significance between high-grade disease and high SUVmean (p = 0.083); no such trend was found between advanced stages and SUVmax (p = 0.268). We observed a significant correlation only between high SUVmax and high-grade disease. No other relationships between SUVmax and SUVmean with biologic and clinical parameters were found. This is probably due to the patient characteristics and to the non-routine use of 18F-FDG PET/CT to stage rare tumors such as MPM.

Abstract
The present work investigated the occurrence of Giardia infection in Chinchilla lanigera reared in three Italian breeding facilities and determined their role as potential zoonotic reservoir. One hundred and four fecal samples were tested for the presence of Giardia spp. cysts using a Direct Fluorescent Assay (DFA). A high positivity rate (39.4%) was found despite all animals were asymptomatic at the time of sampling. Thirty-one positive samples were genetically characterized by sequence analysis of the ITS1-5.8S-ITS2 region of the Giardia ribosomal DNA. Assemblages B (29 isolates) and C (two isolates) were identified. These results showed that Giardia infection can be common in chinchillas, thus spurring further molecular epizootiological studies of the infection to assess the zoonotic potential or host specificity of their isolates, to determine the source of infections, to identify the routes of transmission, and to control the infection among animal populations.

Abstract
Vascular dementia (VAD), the second most common form of dementia after Alzheimer's disease (AD) is characterized by a cognitive deficit of cerebrovascular origin. As for AD, the main proposed treatment is based on cholinesterase inhibitors. However, randomized clinical trials (RCTs) with cholinesterase inhibitors in VAD reported modest - though sometimes statistically significant - clinical efficacy. Non-cholinergic drugs with diverse rationales and mechanisms of action have also been tested in a few RCTs for VAD; the outcomes measured are variable and the evidence of efficacy is weak. The limitations of pharmacological treatment for VAD have prompted a different strategy, i.e. primary prevention aimed at reducing vascular risk factors. Several epidemiological studies reported associations of hypertension, type 2 diabetes, obesity, and inflammation with VAD and in some cases, AD. These all coincide with those of stroke, which in turn is an established factor for cognitive decline and VAD. Here too, only a few RCTs have looked at prevention of these factors, except hypertension. Some pharmacological classes are particularly promising from the clinical and experimental viewpoints: Ca2+ channel blockers and drugs affecting the renin-angiotensin system may act independently of the effects on blood pressure. Despite some conflicting results and the need for further work, the control of risk factors might prevent cognitive decline and VAD in the elderly. The benefit of tackling vascular factors is probably larger when also considering the prevention of stroke. The objective of this review is to analyze the pharmacological treatment and prevention of VAD and their outcome. The literature on Pubmed from 1980 to 2009 was examined.

Abstract
Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect healthcare costs in western countries. Although most patients with colonic diverticula remain asymptomatic for their whole life, in 20-25% of cases will develop symptoms. Antibiotics are commonly used in the treatment of inflammatory complication of diverticular disease. Several clinical observation suggest a role of rifaximin in the management of symptomatic uncomplicated diverticular disease of the colon. This is a critical review of clinical studies addressing the role of long term administration of rifaximin for the treatment of symptomatic colonic diverticular disease. The evidence from prospective controlled trials suggests that rifaximin is effective for obtaining symptomatic relief in patients with uncomplicated diverticular disease. The therapeutic gain compared with fiber supplementation only is approximately 30%. No definitive conclusion can be drawn regard a possible role of rifaximin for preventing diverticulitis.

Abstract
AIM Surgery is an almost inevitable event in Crohn's disease (CD) but is not curative; postoperative recurrence follows a predictable course. Several factors potentially affecting the risk of recurrence have been investigated but results are largely inconclusive. The aim of the present study was to evaluate the long-term course of ileo-caecal CD after surgery and to identify possible predictors of clinical and surgical recurrence. METHODS Patients with ileo-caecal CD who had undergone surgical resection and with at least one year of post-operative follow-up were studied. The postoperative course was retrospectively evaluated. The primary end-points were clinical recurrence (defined as reappearance of symptoms requiring steroid treatment in the presence of endoscopic and/or radiologic recurrence) and surgical recurrence, defined as need for reoperation. RESULTS Two hundred and twelve patients were included in the study. Median follow-up after surgery was 117 months (interquartile range 51-216). The cumulative probability of a post-operative course without clinical and surgical recurrence after 30, 60, 90, 120 months was 78.2%, 69.4%, 58.0%, 50.6% and 97.0%, 96.4%, 85.6%, 72% respectively. Early surgery (within three years from diagnosis) was associated with a longer postoperative course without clinical recurrence compared with late surgery (performed after three years from diagnosis). None of the other clinical variables considered (gender, age, family history for IBD, smoking habits, pattern of CD, and postoperative prophylactic treatment) was associated with the risk of clinical and surgical recurrence. CONCLUSION Surgery is an excellent treatment for patients with isolated ileo-caecal CD. The overall long-term outcome is good: by 10 years after operation approximately 50% of patients are free of clinical recurrence and over 70% do not require further surgery. Surgery, therefore, continues to play an important role in ileo-caecal CD and should therefore not be considered only a failure of medical treatment.

Abstract
The pemetrexed-cisplatin chemotherapy is standard of care in first-line (FL) treatment of malignant pleural mesothelioma (MPM). The second-line (SL) chemotherapy is considered, but the optimal treatment has not been defined yet. The aim of this study was to evaluate the clinical outcomes of SL-therapy in a series of MPM-patients included in a retrospective multicenter database. Clinical records of MPM-patients who received SL-treatment from 1996 to 2008 were reviewed. Study endpoints were response, overall-survival (OS), and progression-free-survival (PFS) for SL, stratified for patient characteristics, FL-outcomes, and type of SL. Out of 423 patients, 181 with full clinical data were identified. Patients' characteristics: median-age 64 years (range: 36-85); male gender 115 (63.5%); good EORTC-score 109 (60.2%); epithelial histology 135 (74.6%). After FL, 147 (81.2%) patients achieved disease-control (DC) and 45 had a time-to-progression≥12 months (TTP≥12). After SL, 95 patients (52.6%) achieved DC (21 response; 74 stable-disease); median PFS and OS were 4.3 and 8.7 months, respectively. According to multivariate analysis, DC after SL-therapy was significantly related to pemetrexed-based treatment (OR: 2.46; p=0.017) and FL-TTP≥12 (OR: 3.50; p=0.006). PFS was related to younger age (<65 years) (HR: 0.70; p=0.045), ECOG-PS0 (HR: 0.67; p=0.022), and FL-TTP≥12 (HR: 0.45; p<0.001). OS was significantly related to ECOG-PS0 (HR: 0.43; p<0.001) and to FL-TTP≥12 (HR: 0.54; p=0.005). In pemetrexed pre-treated patients, re-treatment with a pemetrexed/platinum combination significantly reduced the risk-of-death than pemetrexed alone (HR: 0.11; p<0.001). In conclusion, SL-chemotherapy seems to be active in MPM-patients, particularly in younger patients with ECOG-PS0 and prolonged TTP after FL-pemetrexed-based chemotherapy. In selected patients, re-challenge with pemetrexed-based regimens, preferentially associated with platinum-compound, appears to be an option for SL-setting. Considering the important limitations of this study, due to retrospective nature and the possible selection bias, prospective clinical trials are warranted to clarify these issues.

Abstract
Few studies have been published on bovine piroplasmoses in Italy, and therefore a clear picture of the epidemiology of these infections is difficult to obtain. Vertebrate and invertebrate hosts in Central and Northern Regions of Italy were investigated in 2005 and 2006, when microscopy, molecular tools and serological tests were applied to 468 blood samples drawn from cattle in order to evaluate the presence of these protozoa and identify possible risk factors. Ticks were also collected, identified and analyzed by molecular techniques. Microscopy identified 6.5% of the animals as positive, whereas PCR detected piroplasm DNA in 21.6%. BLAST analysis showed 67 amplicons (17.0%) referable to the Theileria sergenti/buffeli/orientalis group, 17 (4.3%) to Theileria annae, and 1 to Babesia divergens. Serology evidenced a prevalence of 45.4% for Babesia bovis, 17.4% for Babesia bigemina, and 34.9% for B. divergens. The 127 collected ticks were identified as belonging to 5 species, mostly represented by Rhipicephalus bursa, Hyalomma marginatum and Ixodes ricinus. Molecular analyses evidenced the presence of B. bovis and B. bigemina, in 3 and 5 ticks, respectively. Our findings suggest that different species of piroplasms are circulating in bovine populations in Central and Northern Italy, and provide new insights into the complex epidemiology of bovine piroplasmoses in Italy.

Abstract
BACKGROUND Diverticular disease of the colon is a common gastrointestinal disease. Although most patients remain asymptomatic for their whole life, about 20-25% present symptoms related to 'diverticular disease'. Several randomised trials verified efficacy of a poorly absorbed antibiotic, such as rifaximin-α (rifaximin), in soothing symptoms and preventing diverticulitis. AIM To evaluate the long-term efficacy administration of rifaximin plus fibre supplementation vs. fibre supplementation alone, on symptoms and complications, in patient with symptomatic uncomplicated diverticular disease. METHODS Pertinent studies were selected from the Medline, and the Cochrane Library Databases, references from published articles and reviews. Conventional meta-analysis according to DerSimonian and Laird method was used for the pooling of the results. The outcomes were 1- year complete symptom relief, and 1- year complication incidence. The rate difference (RD, with 95% CI) and the Number Needed to Treat (NNT) were used as measure of the therapeutic effect on each outcome. RESULTS Four prospective randomised trials including 1660 patients were selected. The pooled RD for symptom relief was 29.0% (rifaximin vs. control; 95% CI 24.5-33.6%; P<0.0001; NNT=3). The pooled RD for complication rate was -1.7% in favour of rifaximin (95% CI -3.2 to -0.1%; P=0.03; NNT=59). When considering only acute diverticulitis, the pooled RD in the treatment group was -2% (95% CI -3.4 to -0.6%; P=0.0057; NNT=50). CONCLUSIONS In symptomatic uncomplicated diverticular disease, treatment with rifaximin plus fibre supplementation is effective in obtaining symptom relief and preventing complications at 1 year.

Abstract
The aims of this longitudinal study are to investigate general practitioners' opinions and knowledge about colorectal cancer screening in Trentino region, to identify their role and level of participation within the screening program and to find out their formative needs. 174 general practitioners answered the postal self-filled questionnaire: 82% of them asserted their main role in colorectal screening is patient counselling, but many physicians also showed availability to collaborate with the Centre for Health Services of Trento in organizing patients recruitment list and in recovering patients who didn't accept screening invitation. 78% thinks the Health Services of Trento should allocate incentives, especially push money, to promote physicians participation in screening program. Moreover 68% needs a basic formative course about screening programme. Female general practitioners are more prepared to collaborate in organizing patients recruitment list and in handing over the kit for fecal occult blood test than their male colleagues. Instead men prefer to take an active role in counselling and are more interested in economic incentives. The study has found considerable general practitioners support for the introduction of the new screening programme. The info-formative line to improve in Trentino could create a better interface between general practitioners and Centre for Health Services, keeping into account the organizing features of physicians. It seems to be important the definition of shared procedures for the counselling and the requirement of formative courses by general practitioners; the Centre for Health Services of Trento has already undertaken these courses disguised as seminars addressed all health operators.

Abstract
Lip cancer is the most frequent malignant neoplasm of the oral cavity. The study reported herewith refers to the clinico-pathological features and surgical treatment of lip cancer. The most frequent tumour related to the lips is squamous cell carcinoma, with the lower lip more commonly involved than the upper lip. Typically, squamous cell carcinoma originates in the red lip, whereas basal cell carcinoma involves the white lip. The management of lip cancer involves the control not only of the primary tumours with oncologically appropriate margins and subsequent reconstruction to allow oral competence during the oral phase of swallowing, but also the possible metastatic spread to the neck. Reconstruction is a surgical challenge especially for advanced and extended lesions. A successful reconstruction depends on careful pre-operative planning, knowledge of the anatomy and use of the various surgical techniques. Lymph node neck metastases significantly reduce long-term survival. Although the management of the neck is controversial in lip cancer, particularly with respect to the neck, elective or curative supra-omohyoid neck dissection is the best choice for occult or evident loco-regional metastases. Early stage tumours have good prognostic, aesthetic and functional results after surgery compared to the treatment of advanced lesions, which alter the appearance and functionality of the lip. The Authors report their experience in the treatment of lip tumours at the primary site, considering reconstructive problems, together with management of neck metastases.

Isolation and purification of enniatins A, A(1), B, B(1), produced by Fusarium tricinctum in solid culture, and cytotoxicity effects on Caco-2 cells. Toxicon 2010; 56:418-24. [PMID: 20417655 DOI: 10.1016/j.toxicon.2010.04.008] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2009] [Revised: 04/13/2010] [Accepted: 04/16/2010] [Indexed: 10/19/2022]
Abstract
Enniatins (ENs) are antibiotic compounds of hexadepsipeptidic structure produced by several strains of Fusarium spp. The ENs A, A(1), B, B(1) were purified from extracts of Fusarium tricinctum grown on a solid medium of corn, by a low pressure liquid chromatography (LPLC) on reverse phase of Amberlite XAD-7 followed by semipreparative LC. The purity and the structure of the isolated compounds were confirmed by LC-MS/MS. The technique of the purification of the fungal extract enabled complete separation of the ENs A, A(1), B, B(1) with a mean purity of 97% for all the compounds. The cytoxicity of the ENs was tested in the cell lines of human origin (epithelial colorectal adenocarcinoma cells, Caco-2) by MTT assays. Only EN A(1) and B(1) evoked toxicity at the tested concentrations. The inhibitory concentration (IC(50)) for EN A(1) on Caco-2 cells was 12.3 microM, whereas the IC(50) produced by the EN B(1) was 19.5 microM. This study indicates that ENs, fungal metabolites that are commonly found in corn and in general in product composed by corn, may have a toxic potential for human health.
