Abstract
Interleukin (IL)-33 is an important cytokine in the tumour microenvironment; it is known to promote the growth and metastasis of solid cancers, such as gastric, colorectal, ovarian and breast cancer. Our group demonstrated that the IL-33/ST2 pathway enhances the development of squamous cell carcinoma (SCC). Conversely, other researchers have reported that IL-33 inhibits tumour progression. In addition, the crosstalk between IL-33, cancer cells and immune cells in SCC remains unknown. The aim of this study was to investigate the effect of IL-33 on the biology of head and neck SCC lines and to evaluate the impact of IL-33 neutralisation on the T cell response in a preclinical model of SCC. First, we identified epithelial and peritumoural cells as a major local source of IL-33 in human SCC samples. Next, in vitro experiments demonstrated that the addition of IL-33 significantly increased the proliferative index, motility and invasiveness of SCC-25 cells, and downregulated MYC gene expression in SCC cell lines. Finally, IL-33 blockade significantly delayed SCC growth and led to a marked decrease in the severity of skin lesions. Importantly, anti-IL-33 monoclonal antibody therapy increase the percentage of CD4+IFNγ+ T cells and decreased CD4+ and CD8+ T cells secreting IL-4 in tumour-draining lymph nodes. Together, these data suggest that the IL-33/ST2 pathway may be involved in the crosstalk between the tumour and immune cells by modulating the phenotype of head and neck SCC and T cell activity. IL-33 neutralisation may offer a novel therapeutic strategy for SCC.

Abstract
OBJECTIVES The purpose of this study is to assess the prevalence and determinants of workplace violence and the sociodemographic risk factors associated. STUDY DESIGN This was a multicenter cross-sectional study. METHODS The study was performed using self-compiled Italian version of the World Health Organization's questionnaire on workplace violence online by filling in a Google form. The survey was opened from May 2018 to March 2020 and lasted 5-10 min. RESULTS The sample consists of 3659 healthcare workers, of which 2525 (69%) are females, 1446 (39.5%) are nurses, and 2029 (55.5%) are health workers from northern Italy. The most frequent age group of the sample is 50-54 years (16.7%). A total of 366 (10%) healthcare workers are victims of physical aggression at work in the last 12 months, of which 6.3% with a weapon. The risk of being a victim of physical aggression at work in the last 12 months is significantly associated with the following independent variables: male gender (odds ratio [OR] 1.72, 95% confidence interval [CI]: 1.36-2.17), work in southern Italy (OR 1.59, 95% CI: 1.10-2.28), and being a nurse (OR 2.56, 95% CI: 2.01-3.25). The risk of being a victim of physical aggression at work with a weapon in the last 12 months is significantly associated with work in southern Italy (OR 9.33, 95% CI: 3.83-22.73). A total of 1723 (47.1%) of healthcare workers declare to be a victim of verbal aggression at work in the last 12 months. The risk of being a victim of verbal aggression at work in the last 12 months is significantly associated with the following independent variables: work in northern Italy (adjusted OR [aOR] 1.54, 95% CI: 1.32-1.81), work in southern Italy (aOR 3.68, 95% CI: 2.90-4.68), and be more than 55 years old (aOR 0.73, 95% CI: 0.63-0.85). CONCLUSIONS The study underlines that the problem of verbal and physical aggression against healthcare workers is still central and is a further starting point for research. The prevalence of violence is difficult to assess because violent incidents are underreported or unreported. The results of the study suggest that increased awareness is needed to develop effective control strategies at the individual, hospital, and national levels to prevent aggression and improve the conditions of victims.

Abstract

Type of funding sources: None.
Background
The right ventricle-pulmonary artery (RV-PA) coupling is a strong prognostic marker in
several clinical settings, but only few studies focused on its role in repaired Tetralogy of
Fallot (rToF) with pulmonary regurgitation (PR). Aim of this study was to assess
whether differences exist in RV-PA coupling, estimated as by echocardiography,
between patients with rToF and PR with (i-PVR) or without (ni-PVR) indication for
pulmonary valve replacement (PVR).
3
Materials and Methods
The study population included 40 rToF patients allocated to two groups: 20 i-PVR and
20 ni-PVR; 40 healthy controls were also included. All subjects underwent
echocardiogram, while Cardiac magnetic resonance (CMR) was available in 27/40
rToF patients. RV-PA coupling was assessed by echocardiographic TAPSE/PASP and
RV stroke volume/RV end systolic volume (RVSV/RVESV) by CMR.
Results
TAPSE was similar in i-PVR vs ni-PVR (19.0 ± 3.4 vs 18.8 ± 2.7 mm, p = 0.85) while RV-PA coupling
was significantly worse in i-PVR vs ni-PVR (TAPSE/PASP 0.8 ± 0.3 vs 1.1 ± 0.5
mm/mmHg, p = 0.009) as well as in i-PVR vs controls (p = 0.02) while there was no
difference between ni-PVR and controls (p = 0.29). CMR data confirmed the echo
results, with a significant difference in RV-PA coupling between i-PVR and ni-PVR
(RVSV/RVESV 0.9 ± 0.2 vs 1.2 ± 0.3 mL/min/mL, p = 0.01).
Conclusions
This study shows the presence of worse RV-PA uncoupling, despite normal RV systolic
function, in rToF patients with indication to PVR. RV-PA coupling could be a sensitive
marker of a progressive maladaptive RV response to long-standing volume overload in
rToF prior to the onset of clinical symptoms and RV systolic dysfunction. Abstract Figure. example of an i-PVR patient

Abstract
Androgen deprivation therapy (ADT) that antagonizes androgen receptor (AR) signaling has made significant increases to overall survival of prostate cancer patients. However, ADT is not curative, and patients eventually progress to castration resistant disease (CRPC). It has become evident that a subset of prostate cancers acquire ADT resistance through mechanisms independent of AR alteration or reprogramming of AR signaling. This approximately involves a quarter of prostate cancers progressing on ADT. Collectively, these tumors evolve via phenotypic plasticity and display the activation of developmental and stemness gene signatures as well as transitional programs including an epithelial-mesenchymal phenotype. Currently, no successful treatments exist for prostate cancer patients to inhibit or reverse prostate tumor progression that utilizes mechanisms of epi-plasticity. This overview will discuss epigenetic mechanisms that mediate phenotypic plasticity and the potential for targeting the epigenome to create a novel direction for combination strategies involving epigenetic therapy to provide durable response.

Abstract
OBJECTIVE Neutrophils are key effector cells of the innate immune system. They recognize antigens through membrane receptors, which are expressed during their maturation and activation. Neutrophils express FcγRII (CD32), FcγRIII (CD16), and FcγRI (CD64) after being activated by different factors such as cytokines and bacterial products. These receptors are involved with phagocytosis of IgG-opsonized microbes and enhance defense mechanisms. Based on that, our study seeks to compare the expression of FcγRII, FcγRIII, FcγRI, and CD11b on neutrophils from elderly and young subjects and their expression after in vitro activation with cytokines and LPS. METHODOLOGY Neutrophils were isolated from human peripheral blood and from mice bone marrow by density gradient. After isolation, FCγRs expression was immediately analyzed by flow cytometry or after in vitro stimulation. RESULTS In freshly isolated cells, the percentage of FcγRIIIb+ and CD11b+ neutrophils were higher in samples from young individuals; FcγRIIIa expression was more prominent on aged neutrophils; FcγRIA expression was similar in all samples analyzed. Exposure to CXCL8 and LPS resulted in a higher percentage of FcγRIa+ neutrophils on elderly individuals' samples but lower when compared with neutrophils from young donors. We observed that LPS caused an increase in FcγRIIa expression on aging human neutrophils. In contrast, FcγRIIIb expression in response to CXCL8 and LPS stimulation was not altered in the four groups. CD11b expression was lower in neutrophils from elderly individuals even in response to LPS and CXCL8. In mice, we observed differences only regarding CD11b expression, which was increased on aged neutrophils. LPS exposure caused an increase in all FcγRs. CONCLUSIONS Our results suggest that, in humans, the overall pattern of FcγR expression and integrin CD11b are altered during aging and immunosenescence might contribute to age-related infection.

Abstract
Background Coronavirus disease 2019 (COVID-19) is a viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was discovered during the 2019 outbreak in Mainland China and the first cases were reported in Italy on February 21, 2020. This study evaluates the emergency department (ED) attendances of an academic hospital in northern Italy before and after media reported the news of the first infected patients in Italy. Methods Adult attendances in ED in February 2020 were analysed dividing the period into 4 weeks (days 1-7, 8-14, 15-21, 22-28) compared with the same periods in 2019. The visits were analysed separately according to the Italian colour code of triage: white (non-critical), green (low-critical), yellow (medium critical), red (life-threatening). The mean weekly number of attendances was compared with t-test. Results February 2020 total ED attendances compared with February 2019 were 4865 vs 5029 (-3.3%), of which white codes were 834 vs 762 (+9.4%), green 2450 vs 2580 (-5.0%), yellow 1427 vs 1536 (-7.1%), red 154 vs 151 (+2.0%). February 2020 weekly mean ED attendances compared with February 2019 had statistically significant difference only in the fourth week (days 22-28) for green codes (75 vs 92, p = 0.007) and yellow codes (41 vs 52, p = 0.047), not for white (27 vs 26, p = 0.760) and red codes (5 vs 5, p = 0.817). The first three weeks of February 2020 compared with 2019 showed no statistically significant difference in weekly mean ED attendances. Conclusions There was a significant reduction of green and yellow codes attendances at ED in the fourth week of February 2020, corresponding to the initial phase of Italian COVID-19 outbreak. The fear of contracting SARS-CoV-2 by attending the ED probably acted as a significant deterrent in visits, especially for low and medium critical patients. Additional data are required to better understand the phenomenon, including the behaviour of non-critical attendances. Key messages A reduction of green and yellow codes attendances was reported during initial phase of COVID-19 outbreak in an Italian academic hospital. Fear of contracting COVID-19 infection in a hospital setting could impact on emergency department attendances.

Abstract
A 54-year-old female presented to our Emergency Department with acute pulmonary edema. On physical examination she was tachypneic with arterial oxygen saturation of 91% and a grade 3/6 systolic murmur in the apex and left second intercostal space that was irradiated to the intrascapular area. Bilateral femoral and pedal pulses were quite faint on palpation. The blood pressure was 260/120 mmHg. Results of routine blood chemistry were normal with the exception of increased NT-proBNP (2746 pg/mL). Twelve-lead electrocardiogram revealed left ventricular hypertrophy with repolarization abnormalities and left atrial enlargement. The two dimensional (2D) echocardiography showed significant left ventricular hypertrophy (RWT 0.6; LVmass index 150 g/m2), no wall-motion abnormalities and normal left ventricular ejection fraction (EF 60%) but with reduced longitudinal components at TDI evaluation (6 cm/s). Severe ventricular diastolic dysfunction was detected with E/A 2,11 and E/e" 26 with a significant left atrial dilatation (LAVi 73 ml/m2) and severe pulmonary arterial hypertension ( PASP of 85 mmHg) . We were unable to visualize the aortic arch but reduced/absent pulsatile wall motion of abdominal aorta was identified. The patient reported to be affected by unrepaired aortic coarctation diagnosed at the age of 32 during pregnancy. She refused the surgical treatment twice and the she did not undergo any specific follow up but she had several admissions in emergency department for uncontrolled arterial hypertension. Our further evaluation with CT angiography showed a severe narrowing of the post isthmic aortic lumen with significant development collateral vessels (Figure 1). The patient was discharged after resolution of pulmonary edema and titration of hypertension treatment with a planning of hybrid approach to treat the aortic coarctation. The case shows a restrictive cardiomyopathy with post-capillary pulmonary hypertension due to severe unrepaired aortic coarctation.

Abstract
Abstract
Background
Customer satisfaction represents an innovative approach to measure strengths and weaknesses of an organization and is useful for a customer-focused management and culture development. Our survey’s aim was to investigate perceived quality and needs of customers in the university canteen sector.
Methods
Between April and June 2018, an anonymous online questionnaire was distributed by “agenzia regionale per il diritto agli studi superiori” (ARDISS) among university students in Friuli Venezia Giulia, Italy. The questions covered 3 thematic areas: attendance of the service, quality of services and opinions on new initiatives. Furthermore, there was an open question to collect students’ suggestions or proposals to improve the service. Satisfaction about the service was evaluated through five topics: environments, hygiene, staff, meals, global satisfaction. Collected data were analyzed with descriptive, univariate and multivariate analyses. Statistical analyses were performed using 9.4 SAS software.
Results
Response rate was 20.5% (1933/9404). Multiple logistic regression analyses showed a difference in meal choice (entire vs reduced) between institutional canteen and partner cafeterias users (p < 0.0001) and that male (p < 0.0001) and foreign students (p 0.0003) prefer entire meal instead of reduced. Percentage of students who prefer entire meal is reduced (p < 0.0001) if price range increases. Univariate and multivariate analyses showed that high quality perception is associated with lower price range and no suggestions about food and environments (p < 0.0001); multivariate analyses also showed an association between high quality perception and high canteen attendance (p < 0.05).
Conclusions
The survey showed an association between meal choice and students’ profile and between perceived quality and customer’s features. These data and further analyses may help to select areas where an intervention could improve service quality and, therefore, customer satisfaction.
Key messages
Customer satisfaction is an important tool to measure and improve university canteen service quality. These results helped us to identify services’ strengths and weaknesses according to students’ opinions; this could be useful to select improvement areas.

Abstract
Abstract
Background
Residents have a significant role in both patient’s care and daily ward activities; thus, they should be trained to adhere to hospital procedures and to guarantee best clinical practices and patient’s safety. A survey was carried out to assess healthcare workers’ (HCWs) opinions about residents’ role and performance.
Methods
Between February and March 2019, a paper-based/online survey was developed and distributed among both doctors (d) and nurses (n) in 17 (10 medical, 7 surgical) wards of Udine Academic Hospital, Italy. 22 Likert Scale questions (1-totally disagree, 5-totally agree) investigated 5 areas: respect of patient safety and privacy, healthcare quality, clinical risk management, role played within medical team, satisfaction concerning training activities planning. Profession, ward (medical/surgical), age and sex were considered as exposures. Descriptive analysis, median(M)±interquartile range, and ordered logistic regressions were performed with Stata software.
Results
The survey involved 153/785 HCWs’ (112/477 nurses and 41/308 doctors). All the units were represented with at least 1 HCWs; answers from both categories were collected in 82% of wards. Data analysis showed that nurses gave lower scores about residents’ respect of patient privacy than doctors: patient privacy protection: M(d)=4±0, M(n)=4±1, OR(d/n) 2.60, [95%CI, 1.04-6.52]; sensitive data management: M(d)=4±0, M(n)=3±1, OR(d/n) 2.97, [95%CI, 1.26-7.02]. The same resulted regarding clinical risk management: patient record management: M(d)=4±0, M(n)=3±2, OR(d/n) 13.64 [95%CI 5.30-35.12]; proper hand hygiene: M(d)=4±1, M(n)=3±1, OR(d/n) 5.56 [95%CI 2.35-13.17]; incident reporting: M(d)=4±1, M(n)=3±2, OR(d/n) 7.05 [95%CI 3.14-15.86].
Conclusions
Nurses appeared to be more critical than doctors about residents performances in safety and privacy and clinical risk management areas. Reasons behind these different opinions should be investigated in order to improve constantly healthcare’s quality.
Key messages
Residents hold a key role in healthcare quality, therefore it is significant evaluate their practice regarding patient’s safety and privacy. Doctors and nurses opinions on residents adherence to hospital procedures in order to guarantee best clinical practices and patient’s safety differ significantly.

Abstract
Abstract
Background
Perioperative antimicrobial prophylaxis is a key practice to prevent surgical site infection. The Udine Healthcare and University Integrated Trust has defined its features in a specific procedure, available on the hospital Intranet. Compliance with the procedure has been monitored on a semi-annual basis.
Methods
Between July 2013 and December 2018 15 clinical records per semester for each one of the 16 surgical units were randomly extracted, including ordinary admissions with clean or clean/contaminated surgery. Compliance with the procedure was monitored for all the items considered: drug, dosage, timing of administration, redosing and duration of prophylaxis. A first comparison analysis both between semesters and for longer time frames was performed with the chi-square test; to evaluate the presence of a linear trend all over time (in semestres), the Pearson linear correlation coefficient was calculated; in case of correlation, a simple two-variable linear regression analysis was performed. Statistical significance was assessed for p < 0.05.
Results
A sample of 2775 records was evaluated. Focusing on the first and last semester of monitoring, overall compliance increased in 9 of the 16 units, although there is a drop, when extending the analysis to the whole sample (72% vs 70.8%) with no statistical significance. Otherwise a statistically significant difference is recorded between the first and the last two years of analysis (p <0.007), with an increase of overall compliance from 64.2% (2013-2014) to 69.7% (2017-2018). Finally a strong and significant negative correlation between time and overall compliance to redosing emerges (r = -0.79; p = 0.004).
Conclusions
Compliance with hospital procedure has substantially improved over time reaching a stable performance value. However the linear regression analysis highlights the need to implement new intervention strategies in order to increase overall compliance to redosing.
Key messages
Overall compliance with hospital procedure has improved over time. Results highlight the need to implement new intervention strategies.

Abstract
Abstract
Background
Heart failure is becoming the most prominent cause of death among patients with Duchenne Muscular Dystrophy (DMD) and end-stage cardiomyopathy (CMP). Implantation of left ventricular assist devices (LVAD) as destination therapy (DT) in this group of patients is still matter of debate. No current data are available on long-term follow- up of young patients.
Purpose
The aim of this study was to evaluate the long-term outcome of LVAD in DMD end stage heart failure (HF) compared to a group treated optimal medical treatment (OMT) with inotropes
Methods
All patients affected by DMD patients presenting with end-stage HF receiving OMT or LVAD have been reviewed. All data about characteristics of HF at presentation including assessment of nutritional status and respiratory function, left ventricular ejection fraction, brain natriuretic peptide, serum sodium, in-hospital treatment and long term follow up have been collected. OMT group was constituted by 4 patients matching implantation VAD criteria but not eligible or refusing treatment. Survival was represented by Kaplan Meier analysis.
Results
A total of 12 DMD patients with end-stage CMP were considered for this analysis. 8 have been implanted with LVAD during the period from 2011 until mid-2017 and compared with 4 treated with OMT. Mean systolic pressure was 103 versus 91 mmHg in those not receiving LVAD (p=0.2), and left ventricular ejection fraction at the time of presentation was 16‰ for LVAD group and 22‰ for the second group (p=0.1). LVADs improved survival throughout follow-up for patients undergoing baseline inotropic infusions (P=0.0014); for the LVAD group versus the OMT group, 1-month survival was 100‰ and 67‰ respectively and 2-month survival was 100‰ versus 0‰. For LVAD group survival was 86‰ at one year, 71‰ at 2 years and 48‰ at 5 years from implantation. Analysis on short and long-term follow-up showed significant improvement of survival in DMD patients treated with LVAD (log rank<0.001), with a 5-year increase in life expectancy.
Conclusions
LVAD improved outcomes in patients with LVAD when compared to those without. Long-term follow-up was similar to DT LVAD adult population. Further studies are necessary to confirm these data.

Abstract
Squamous cell carcinoma (SCC) is the second most common form of skin cancer and the mechanism(s) involved in the progression of this tumor are unknown. Increases in the expression of IL-33/ST2 axis components have been demonstrated to contribute to neoplastic transformation in several tumor models and interleukin-33 is correlated with poor prognosis of patients with squamous cell carcinoma of the tongue. Based on these observations, we sought to determine the role of the IL-33/ST2 pathway during the development of SCC. Our findings show that ST2-deficiency led to a marked decrease in the severity of skin lesions, suggesting that ST2 signaling contributed to tumor development. An analysis of tumor lesions in wild-type and ST2KO mice revealed that a lack of ST2 was associated with specific and significant reductions in the numbers of CD4+ T cells, CD8+ T cells, dendritic cells, and macrophages. In addition, NK cells that were isolated from ST2KO mice exhibited higher cytotoxic activity than cells isolated from wild-type mice. Notably, ST2 deficiency resulted in lower IFN-γ, TNF-α, IL-10, and IL-17 production in tumor samples. Our findings indicate that the IL-33/ST2 pathway contributes to the development of SCC by affecting leukocyte migration to tumor microenvironment and impairing NK cytotoxic activity.

Abstract
The prevalence and characteristics of interictal headache, epilepsy and headache/epilepsy comorbidity were assessed in 858 women and 309 men aged 18-81 years from headache and epilepsy centers in Italy. The research hypothesis was that comorbidity among patients with either disorder would be expected to be higher than in the general population. Interictal headache was diagnosed in 675 cases (migraine 482; tension-type headache 168; other types 25), epilepsy in 336 (partial 171; generalized 165) and comorbidity in 156 (1.6% from headache centers; 30.0% from epilepsy centers). Patients with epilepsy, headache and comorbidity differed in a number of demographic and clinical aspects. However, for both headache and epilepsy, a family history of the same clinical condition was equally prevalent in patients with and without comorbidity. These findings do not support the purported association between headache and epilepsy.

Abstract
Abstract
BRCA1 plays a critical role in DNA-damage repair mechanisms elicited by cell exposure to anti-tumor agents. HCC1937 is a BRCA1-defective breast cancer cell line which discloses higher sensitivity to cisplatinum (CDDP) as compared to the BRCA1 full-length cDNA transfected clone, HCC1937/wtBRCA1. By cDNA microarray whole gene expression profile and Ingenuity Pathway Analysis (IPA) software, we found a differential modulation of Notch signaling after CDDP exposure in HCC1937 cell line as compared to BRCA1-reconstituted clone with a strong down-regulation of Notch1, 2 and 3 expression together with other genes involved in the Notch signaling network, including Hes1 and Jag1. Notch pathway was not affected by CDDP exposure in BRCA1-reconstituted cells. By Western Blot analysis, we next analyzed if the different trascriptional response of the two cell lines to CDDP occurred together with down-regulation of Notch protein in BRCA1-defective cells. We found enhanced expression of BRCA1 in BRCA1-transfected cells. We then analyzed the Notch 3 protein's expression in HCC1937 and HCC1937/wtBRCA1. By Western blot analysis, we demonstrated a significant reduction of Notch 3 protein's expression following CDDP exposure at the IC50 dose for 12, 18 and 24 hours, in HCC1937 as compared to HCC1937/wtBRCA1, consistently with gene expression results. In the aim of evaluating the role of Notch signaling in the regulation of the pharmacological response to CDDP in BRCA1-defective cells, we exposed HCC1937 cells to the pan-Notch inhibitor, γ-secretase inhibitor XII (GSI-XII), alone or in combination with CDDP, and we elvaluated, by MTT assay, in vitro growth effects on cell survival. We observed a time and dose dependent decrease of cell growth of HCC1937 following GSI-XII exposure as compared to BRCA1-reconstituted clone, with an IC50 between 25 and 35 microM as single agent, while HCC1937/wtBRCA1 where highly resistant to the drug. The combination of GSI-XII plus CDDP produced a significant sinergistic antitumor effect at 48 hours in HCC1937 which did not occurred in HCC1937/wtBRCA1. Our findings suggest that the high sensitivity of BRCA1-defective cells to CDDP exposure may be related not only to depression of the DNA-damage repair machinery but also to down-modulation of the Notch survival pathway. Moreover, our data indicate that the antitumor activity of CDDP is enhanced by combination with the Notch inhibitor GSI-XII suggesting that γ-secretase inhibitors may represent a potential and novel therapeutic tool in this specific setting.

Abstract
Drug treatment and specific immunotherapy (SIT) are both effective in seasonal rhinoconjunctivitis, but the former acts only on allergic symptoms while the latter modifies the natural history of the disease. Only a few studies compared the clinical efficacy of the two treatments with contrasting results. We planned a study to compare the efficacy of SIT (15 patients) and drug treatment (15 patients) in moderate to severe seasonal rhinoconjunctivitis caused by sensitization to grass pollen. SIT was performed by a 5-grass extract standardized in IR and absorbed onto calcium phosphate (Phostal, Stallergénes, Antony, France) using the conventional build-up phase in 12 weeks and a maintenance treatment with monthly injection for three years. Drug treatment was done with cetirizine as antihistamine, mometasone furoate as nasal topical steroid, and levocabastine eyedrops. All patients registered during the pollen season their symptoms and drug consumption. After one year 12 of 15 patients treated with SIT had less symptoms and drug consumption in respect to baseline compared to none in drug treated group (p = 0.021) and after three years 15 of 15 were improved in group A compared to one of 15 in group B (p = 0.008). These findings indicate an higher efficacy of SIT in patients with seasonal rhinitis not only in the long term but also in the first year of treatment.

Abstract
Foot involvement is very frequent in patients affected by psoriatic arthritis (PsA). However, evaluation of the painful foot can be problematic, because it is often difficult to distinguish between arthritis, tenosynovitis, and enthesopathy. Plain radiographs can show bone erosion or other features of joint involvement, but give little information about the soft tissues. We therefore studied foot involvement in 31 PsA patients using high resolution sonography, and compared the results with the findings on x-ray and clinical examination. Ultrasound revealed pathological findings in a large proportion of the patients, most of whom exhibited no clinical (pain or swelling) or radiological signs of foot involvement at the time of the study. Our data suggest that involvement of the tendons and entheses may be more frequent in PsA patients than has thus far been supposed, even in cases of not particularly aggressive disease, and that clinical evaluation tends to underestimate these manifestations.

Abstract
OBJECTIVE To compare axial and coronal fast Spin-Echo fat-suppressed T2-weighted sequences with three-dimensional (3D) maximum intensity projection (MIP) images in patients with suspected pancreaticobiliary obstruction. MATERIAL AND METHODS MR cholangiopancreatography (MRCP) was performed in 108 consecutive patients with a non-breath-hold, fat-suppressed, 2D, heavily T2-weighted fast spin-echo sequence in coronal plane. Axial T1- and T2-weighted images were previously obtained. In addition, 3D reconstructions of the coronal images were analysed separately by using a MIP algorithm. Both two-dimensional (2D) (axial and coronal) and 3D MIP images were separately evaluated by two readers in conference and their results were compared with that of endoscopic retrograde cholangiopancreatography, percutaneous trans-hepatic cholangiography, surgery and/or imaging follow-up. Statistical analysis of 2D and 3D MRCP images in diagnosing the level and probable cause of pancreaticobiliary obstruction were separately calculated. RESULTS 106/108 of MRCP examinations were judged diagnostic by the two reviewers for adequacy of visualisation of the biliary and pancreatic ducts. Sensitivity, specificity, positive predictive value, negative predictive value and global diagnostic accuracy of 2D (axial and coronal) and 3D MRCP images in diagnosing the pancreaticobiliary obstruction were 94 and 57%,, 95 and 93%, 97 and 92%, 91 and 60%, 94 and 72% respectively. CONCLUSION Our results do indicate a higher global accuracy for axial and coronal fast Spin-Echo fat-suppressed T2-weighted sequences versus 3D MIP images in diagnosis of the level and probable cause of pancreaticobiliary obstruction and stress the limitations of 3D images in depiction of small intraductal pathology such as calculi and biliary neoplastic.

Abstract
The purpose of this study was to evaluate the diagnostic accuracy of MR cholangiopancreatography (MRCP) in the detection of common bile duct stones. A series of 286 consecutive patients were referred for MRCP, that was performed with a 1.5 T MR unit, through a non-breath-hold, respiratory-triggered, fat-suppressed, two-dimensional, heavily T2-weighted fast spin-echo sequence in the coronal plane. Axial T1 and T2-weighted sequences were first obtained. Axial, coronal, and Maximum Intensity Projection images were evaluated by three independent readers, who were asked to determine whether stones were present or not inside the biliary tract. The findings of MRCP images were compared with endoscopic retrograde cholangiopancreatography, percutaneous trans-hepatic cholangiography, intra-operative cholangiography, surgical, or imaging follow-up findings. Two-hundred and seventy-eight out of 286 MRCP examinations were judged diagnostic by the three reviewers. Among the 278 patients included in our study group, biliary tract lithiasis was proved in 76 cases (27%). On the basis of reviewers' reading, MRCP had sensitivity 92-93%, specificity 97-98%, positive predictive value 91-93%, negative predictive value 97-98%, and the diagnostic accuracy ranged between 95% and 96% in the detection of calculi. Interobserver agreement was excellent (K = 0.84, kappa statistic). MRCP showed a high diagnostic accuracy and an excellent inter-observer agreement in the detection of common bile duct stones.

Abstract
Eighty-nine patients with 108 adrenal masses, either adenomas (n = 88) or malignant lesions (n = 20), underwent magnetic resonance imaging (MRI) of the abdomen at 0.5 T for the purpose of determining whether adrenal adenomas could be differentiated from malignant lesions on gadolinium-enhanced fat-suppressed T1-weighted spin-echo (SE) images (Gd-E FS T1WI) and on T2-weighted SE images. The imaging protocol included conventional unenhanced SE T1- and T2-weighted sequences and Gd-E FS T1WI. Three observers independently evaluated signal intensity on unenhanced and enhanced images and also the presence of structures of high signal intensity in the outer margin [hyperintense rim sign (HRS)] or in the center [hyperintense central spot (HCS)] of the adrenal masses. Forty-one (46.5%) of 88 adenomas were homogeneously isointense to liver in unenhanced and enhanced T1-weighted sequences and in T2WI. HCS and HRS were observed in 33/88 (37.5%) and 15/88 (17%) adenomas, respectively, on Gd-E FS T1WI; in contrast, these signs were never revealed in any case of malignant lesions. Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy in classifying lesions as suggestive of adenoma were 93%, 90%, 98%, 75%, and 93%, respectively. Visual evaluation of details of tumor structures on Gd-E FS T1WI allows good characterization of adrenal masses. HCS, HRS, and homogeneous isointensity to liver are characteristic signs of adrenal adenomas.

Abstract
OBJECTIVES This study describes the magnetic resonance findings of benign and malignant pleural diseases in asbestos-exposed subjects. METHODS Thirty patients with a history of asbestos exposure and pleural lesions in chest X-rays and computed tomography scans were examined with a 0.5- and a 1.5-T magnetic resonance unit. The examination protocol included cardiac-gated proton density and T2-weighted images, unenhanced and enhanced (Gd-DTPA; 0.1 mmol/ kg) T1-weighted images in the axial plane and sometimes in another orthogonal plane (sagittal or coronal or both). All the magnetic resonance images were reviewed by 3 experienced observers, who visually evaluated morphologic features, signal intensity, and contrast enhancement of pleural lesions. The diagnosis was established by means of percutaneous biopsy, thoracotomy, and combined clinical and radiological follow-up for at least 3 years. RESULTS Eighteen patients affected with multiple pleural plaques showed low signal intensity on both unenhanced and enhanced T1-weighted and proton density and T2-weighted images. In 2 of these patients an acute pleural effusion was observed. All the malignant lesions (11 mesotheliomas) and a solitary benign pleural plaque revealed high signal intensity on the proton density and T2-weighted images and inhomogeneous contrast enhancement in the postcontrast T1-weighted images. The sensitivity, specificity, and diagnostic accuracy of the magnetic resonance imaging in classifying a lesion as suggestive of malignancy were 100%, 95% and 97%, respectively. CONCLUSIONS The results point out 2 magnetic resonance signal intensity patterns for asbestos-related pleural lesions: (i) low-signal intensity on unenhanced and enhanced T1-weighted and proton density and T2-weighted images for benign plaques and (ii) nonhomogeneous hyperintensity in T2-weighted and enhanced T1-weighted images for malignant mesotheliomas.

Abstract
PURPOSE To evaluate the feasibility of surface-rendered magnetic resonance virtual endoscopy (MRVE) of magnetic resonance cholangiopancreatography (MRCP) data sets. We retrospectively reviewed MR cholangiopancreatography data sets of 120 patients with biliary stone (n=40), inflammatory ampullary stenosis (n=12), pancreatic tumor (n=8), cholangiocarcinoma (n=7), stenosis of surgical bilio-enteric anastomosis (n=4), extrinsic localized common bile duct stenosis (n=2), ampullary carcinoma (n=2), pancreatic duct stone (n=1), tumor of the gallbladder (n=1), and normal pancreaticobiliary tree (n=43). MRVE views were generated with Navigator software. Segmentation of the acquired data sets was performed with a thresholding technique. Navigation sequences were simulated through the entire biliary tract. MRVE was obtained in 27 (63%) of the 43 normal patients. Endoscopic views were generated in all 77 patients with partial or complete obstruction of the pancreaticobiliary tree. Among these, three groups of patterns were identified: 36 (47%) endoluminal masses (polyp-like masses), 17 (22%) luminal stenoses, 24 (31%) luminal occlusion. In 29 cases, hole artifacts through the internal wall were observed and interpreted as mistakes of segmentation. MRVE proved to show the internal anatomy of the biliary tract and endoluminal changes due to pathological condition. Further investigations are needed to test the usefulness and the potentialities of this technique.

Abstract
It has been suggested that an appropriate timing of puberty is necessary for normal bone mineral density (BMD) acquisition, which may not be achievable in children with constitutional delay of puberty (CDP). To assess the effect of pubertal delay on BMD, we measured areal BMD (aBMD) at lumbar spine, by dual-energy x-ray absorptiometry (DEXA), in a group of patients with CDP (n=21; mean age, 21.8+/-1.7 yr) at final height and in healthy controls (n=12; mean age, 19.3+/-1.3 yr). A subset of seven patients (group a) were untreated, whereas six subjects (group b) had received im testosterone depot (100 mg/month, for 6-12 months) and 8 boys (group c) oral oxandrolone (1.25-2.5 mg/daily, for 6-28 months) for their pubertal delay. Volumetric BMD (vBMD) was calculated from DEXA measurements. aBMD was reduced in patients with CDP (1.101+/-0.134 g/cm2), in comparison with controls (1.222+/-0.091 g/cm2; P < 0.009); no significant differences were found among the groups (group a, 1.089+/-0.133 g/cm2; group b, 1.111+/-0.118 g/cm2; group c, 1.103+/-0.160 g/cm2). vBMD was not significantly different in patients with CDP (0.327+/-0.021 g/cm3) and in controls (0.337+/-0.017 g/cm3; P= not significant); no significant differences were found among the groups (group a, 0.326+/-0.016 g/cm3; group b, 0.332+/-0.022 g/cm3; group c, 0.330+/-0.021 g/cm3). No differences were found in mineral metabolism and in bone markers between patients and controls; patients did not report an increased fracture rate, compared with controls. Our data indicate that: 1) men with CDP have normal vBMD; 2) the reduced aBMD may be the result of uncritical use of DEXA measurements in subjects with altered growth pattern; and 3) androgen administration during pubertal years did not improve BMD in young men with a history of CDP.

Abstract
UNLABELLED To evaluate the effect of central precocious puberty (CPP) and its treatment with gonadotropin-releasing hormone (GnRH) analogues on final height and peak bone mass (PBM), we measured lumbar bone mineral density (BMD) in 23 girls at final height. Patients were distributed in two groups. Group 1: 14 patients with progressive CPP were treated with GnRH analogues; seven patients received buserelin (1600 microg/daily), subsequently switched to depot triptorelin (60 microg/kg/26-28 days); seven patients were treated with depot triptorelin (60 microg/kg/26-28 days); mean age of treatment was 6.2 years (range 2.7-7.8 years); the treatment was discontinued at the mean age of 10.1 years (range 8.7-11.3 years); final height was reached at the mean age 13.4 years (range 12.0-14.9 years). Group 2: 9 patients (mean age 6.5 years, range 4.8-7.7 years) with a slowly progressing variant of CPP were followed without treatment; final height was reached at the mean age 13.6 years (range 12.5-14.8 years). Lumbar BMD (L2-L4 by dual energy X-ray absorptiometry) was measured in all patients at final height. In group 1, final height (158.9+/-5.4 cm) was significantly greater than the pre-treatment predicted height (153.5+/-7.2 cm, P < 0.001), but significantly lower than mid-parental height (163.2+/-6.2 cm, P < 0.005). Subdividing the girls of group 1 according to the bone age at discontinuation of therapy (i.e. < or =11.5 years, n=5, or > or =12.0 years, n=9), the former patients had a final height significantly higher than the latter (163.7+/-3.9 cm vs 156.5+/-4.6 cm, P < 0.02). In group 2, final height (161.8+/-4.6 cm) was similar to the pre-treatment predicted height (163.1+/-6.2 cm, P=NS) and was not significantly different from mid-parental height (161.0+/-5.9 cm). BMD values (group 1: 1.11+/-0.14 g/cm2, group 2: 1.22+/-0.08 g/cm2) were not significantly different from those of a control group (1.18+/-0.10 g/cm; n=20, age 16.3-20.5 years) and the patients' mothers (group 1: 1.16+/-0.07 g/cm2, n=11, age 32.9-45.1 years; group 2: 1.20+/-0.08 g/cm2, n=7, age 33.5-46.5 years). In group 1, the girls who stopped therapy at a bone age < or =11.5 years had significantly higher BMD (1.22+/-0.10 g/cm2) compared to those who discontinued therapy at a bone age > or =12.0 years (1.04+/-0.12 g/ cm2, P < 0.05). CONCLUSION In girls with progressive CPP, long-term treatment with GnRH analogues improves final height. A subset of patients with CPP does not require treatment because good statural outcome (slowly progressing variant). In CPP, the abnormal onset of puberty and the long-term GnRH analogue treatment do not impair the achievement of PBM. In GnRH treated patients, the discontinuation of therapy at an appropriate bone age for pubertal onset may improve both final height and PBM.

Abstract
PURPOSE We reviewed the imaging patterns of the villous-lipomatous proliferation of the knee synovial membrane (lipoma arborescens), with special reference to the role of MRI in the diagnosis of this rare condition. MATERIAL AND METHODS 1994 to 1996, we examined four patients, none of them with a history of knee trauma. The clinical picture was characterized by moderate and painful suprapatellar swelling in three cases and by moderate suprapatellar swelling alone in one case. All patients were examined with conventional radiography and MRI; two were submitted to US and two to CT. The diagnosis of lipoma arborescens was suggested on the basis of imaging patterns and then confirmed by histologic findings. RESULTS Conventional radiography showed a roughly oblong slim opacity in the suprapatellar recess in all cases; the joint space was always preserved. US showed a villous lesion surrounded by fluid, but provided no specific data on its nature. CT and MRI not only provided better location and morphologic detailing and showed the relationships with articular structures better, but also permitted the direct identification of the fat nodules within the abnormal synovial reaction. CONCLUSION We stress the role of MRI in suggesting the correct diagnosis of lipoma arborescens, as it was subsequently confirmed in our series by histologic findings. In fact, fat-suppression sequences, after T1-weighted SE, can typify fat tissue.

Abstract
The purpose of the study is to evaluate the ability of Gd-enhancement and fat-suppressed MR imaging operating at midfield strength to characterize incidentally discovered adrenal masses. Sixty patients with 72 adrenal masses incidentally discovered during US or CT exams were studied with a 0.51 MR unit following clinical and laboratory evaluation. After Gd-DTPA intravenous administration a modified three-point Dixon technique was performed in all patients. This technique provided three images sets: conventional T1-weighted SE images, fat-suppressed T1-weighted images and water-suppressed T1-weighted images. Diagnosis was established by means of surgery (11 lesions), fine-needle biopsy (21 lesions) and stability on ultrasonographic follow-up for at least 1 year (range, 12-87 months) from adrenal lesion discovery (40 masses). In most of adenomas (n = 55) an homogeneous enhancement was observed on postcontrast T1WI; however, 15 out of these lesions showed a small focal spot of high intensity in Gd-enhanced fat-suppressed images. On the contrary, malignant conditions (n = 6) and pheochromocytoma (n = 1), all had inhomogeneous signal intensities which were relatively higher after Gadolinium injection as compared with the liver. The fat suppression technique demonstrated areas of bright signal intensity related to high vascularity. The performance of three observers in order to differentiate malignant from benign conditions showed sensitivity, specificity, diagnostic accuracy, positive and negative predictive values of 100, 88.5, 90, 50 and 100% on the basis of gadolinium enhancement only, by utilizing the Dixon technique. In conclusion, although Gd-enhancement and fat-suppressed sequence helped correctly differentiate among the groups of incidentally discovered adrenal masses, the degree of overlap suggests that it is still difficult to characterize individual patients. However, the modified three-point Dixon technique after contrast material administration appears to be a further capability of midfield MRI in the characterization of adrenal tissue.
