Objectives Forty sites were involved in this multicenter and multivendor registry, which sought to evaluate indications, spectrum of protocols, impact on clinical decision making and safety profile of cardiac magnetic resonance (CMR). Materials and methods Data were prospectively collected on a 6-month period and included 3376 patients (47.2 ± 19 years; range 1-92 years). Recruited centers were asked to complete a preliminary general report followed by a single form/patient. Referral physicians were not required to exhibit any specific certificate of competency in CMR imaging. Results Exams were performed with 1.5 T scanners in 96% of cases followed by 3 T (3%) and 1 T (1%) magnets and contrast was administered in 84% of cases. The majority of cases were performed for the workup of inflammatory heart disease/cardiomyopathies representing overall 55.7% of exams followed by the assessment of myocardial viability and acute infarction (respectively 6.9% and 5.9% of patients). In 49% of cases the final diagnosis provided was considered relevant and with impact on patient's clinical/therapeutic management. Safety evaluation revealed 30 (0.88%) clinical events, most of which due to patient's preexisting conditions. Radiological reporting was recorded in 73% of exams. Conclusions CMR is performed in a large number of centers in Italy with relevant impact on clinical decision making and high safety profile. © 2013 Elsevier Ireland Ltd.

Objectives: To evaluate the performance of the Birmingham Vasculitis Activity Score (BVAS) v3 and the Disease Extent Index (DEI) for the assessment of disease activity in 4 primary childhood (c-) systemic vasculitides. Methods: Patients fulfilling the EULAR/ PRINTO/PRES (Ankara) c-vasculitis classification criteria for Henoch-Schönlein purpura (HSP), childhood (c) polyarteritis nodosa (c-PAN), c-Wegener's granulomatosis (c-WG) and c-Takayasu arteritis (c-TA) with disease duration at the time of diagnosis ≤3 months were extracted from the PRINTO database. The performance of the BVAS and DEI were examined by assessing convergent validity, the pattern of disease involvement, and responsiveness. We also evaluated alternative unweighted scoring methods for both tools. Results: The analysis set included 796 patients with 669 HSP, 80 c-PAN, 25 c-WG and 22 c-TA. The median age at diagnosis was 6.9 years (6.6-12) and median delay in making the diagnosis from the onset of signs/symptoms was 0.01 (0.003-0.027) years. A strong correlation was found between the BVAS and DEI (rs=0.78) while correlation with the physician global assessment was moderate (rs=0.48) with BVAS and poor with DEI (rs=0.25). Both the BVAS and DEI sub-scores and total scores were able to descrive the disease involvement in the 4 childhood vasculitides. Responsiveness was large (>1.5) for both tools. The performance characteristics of the BVAS and DEI with the unweighted methods were comparable. Conclusion: This study demonstrates that both the BVAS and DEI are valid tools for the assessment of the level of disease activity in a large cohort of childhood acute and chronic vasculitides. © Clinical and Experimental Rheumatology 2012.

Background and aims: The aim of the present study was to determine whether age and gender affect the imbalance between oxidant production and antioxidant levels in age-related macular degeneration (ARMD) patients. Methods: Total superoxide dismutase (T-SOD), total glutathione peroxidase (T-GSHPx), and catalase (CAT) activities, as well as malondialdehyde (MDA), protein carbonyl (PC), 8-Hydroxy-29-deoxyguanosine (8-OHdG) and total oxidation status (TOS) levels, were measured in the following groups subdivided by age and gender: 156 early-ARMD patients; 80 wet-late ARMD patients; 72 dry-late ARMD patients; and 207 healthy controls. Results: Among all study participants, women aged 50-54 had higher T-SOD and T-GSHPx activities and lower MDA, PC, TOS and 8-OHdG levels than age-matched men (p<0.05), whereas older women were not significantly different from age-matched older men. Significantly increased oxidative damage was associated with ARMD patients >60 years of age in both sexes compared with controls (p<0.01 for 60-64 and 65-69-year-old ARMD sub-groups; p<0.001 for 70-74 and 75-80-year-old ARMD subgroups). Multiple regression analysis demonstrates that age significantly affects antioxidant status and oxidative damage in ARMD patients compared with controls (controls, p<0.05; ARMD patients, p<0.001). A direct correlation with antioxidant enzyme activities and an inverse correlation with oxidative DNA, protein and lipid damage were also observed in premenopausal women (controls, p<0.05; ARMD patients, p<0.001). Conclusions: Aging and postmenopausal status may be aggravating factors contributing to redox imbalance and oxidative damage in ARMD patients. ©2012, Editrice Kurtis.

Early noninvasive identification of cardiac amyloidosis (CA) is of growing clinical importance. Low voltage on electrocardiogram (ECG), increased left ventricular (LV) septal thickness (ST), and global longitudinal strain (GLS) on echocardiography, and elevated brain natriuretic peptides (BNP) are used as surrogates of CA. Thirty-five patients (50 ± 14 years, 22 women) underwent electrocardiography to analyze low-voltage QRS (<15 mV) pathologic Q waves, poor R-wave progression, ST-T abnormalities, and left bundle branch block. An ECG was considered abnormal if at least one ECG alteration was present. Echocardiography was used to analyze LVST, E/E′, and GLS. All participants also had BNP blood testing. 99mTc-3,3-diphosphono-1,2 propanodicarboxylic acid scintigraphy assumed as a reference method showed CA in 18 patients (51%, CA group) and no accumulation in 17 patients (no CA group). In descending order of accuracy, LVST >14 mm, E/E' >6.6, GLS <14.1, BNP >129 pg/ml, and an overall abnormal ECG showed good capability to distinguish patients with and without CA. All these parameters were predictors of CA in univariate analysis, whereas low-voltage QRS showed the worst performance. LVST >14 mm (p = 0.002) was the best independent predictor of CA, achieving sensitivity of 78% and accuracy of 89%. However, an LVST >14 mm (p = 0.005) plus an abnormal ECG (p = 0.03) show together a greater sensitivity, equal to 89%, in identifying CA. An integrated evaluation of ECG and echocardiography is a sensitive and low-cost technical approach to identify CA in patients with transthyretin gene mutation. © 2015 Elsevier Inc.

Background FOXE1 is a candidate tumour suppressor gene at human chromosome locus 9q22. This is a region frequently lost in squamous cell cancer. Objectives To assess the influence of FOXE1 variations on genetic susceptibility to cutaneous squamous cell carcinoma (SCC). Methods We performed mutational analysis of FOXE1 in 320 DNA samples isolated from 60 SCC specimens, 60 adjacent histologically normal skin samples and 200 blood samples. Results No somatic mutations were evident. Instead the polyalanine tract showed marked variation in its length between samples from patients with SCC and normal controls. Conclusions These results imply that another tumour suppressor gene at this locus may be more important than FOXE1 in skin carcinogenesis and suggest that variation in the FOXE1 polyalanine tract length predisposes to cutaneous SCC. © 2009 British Association of Dermatologists.
