Our study aims at disclosing epidemiology and most relevant clinical features of esophageal atresia (EA) pointing to a model of multicentre collaboration.A detailed questionnaire was sent to all Italian Units of pediatric surgery in order to collect data of patients born with EA between January and December 2012. The results were crosschecked by matching date and place of birth of the patients with those of diagnosis-related group provided by the Italian Ministry of Health (MOH).A total of 146 questionnaires were returned plus a further 32 patients reported in the MOH database. Basing on a total of 178 patients with EA born in Italy in 2012, the incidence of EA was calculated in 3.33 per 10,000 live births. Antenatal diagnosis was suspected in 29.5% patients. 55.5% showed associated anomalies. The most common type of EA was Gross type C (89%). Postoperative complications occurred in 37% of type C EA and 100% of type A EA. A 9.5% mortality rate was reported.This is the first Italian cross-sectional nationwide survey on EA. We can now develop shared guidelines and provide more reliable prognostic expectations for our patients.

High-resolution ultrasound (US), as a readily available, cost-effective and harmless imaging technique, is appropriately the initial imaging modality for salivary gland lesions. Benign tumors are reported topresent with regular and well-defined margins, a homogeneous hypoechoic structure and demarcated vessel distribution, whereas malignant lesions are irregular, heterogeneous and diffusely perfused. Ultrasound and color Doppler features of benign and malignant salivary gland lesions overlap, and many benign tumors, particularly pleomorphic adenomas, may appear irregularly shaped, with a heterogeneous echo-structure indistinguishable from a malignant lesion. Often skilled US operators are not always able to differentiate benign from malignant lesions. The introduction of US contrast agents has allowed further perspectives in the possible improvement of lesion characterization, and the emergence of US elastography, an innovative tool for assessing lesion stiffness/elasticity characteristics, has been advocated for differentiating salivary gland lesions. When lesions are atypicalon US, contrast-enhanced magnetic resonance (MR) imaging is usually the definitive imaging modality. We present a current review of benign and malignant parotid gland tumors with emphasis on the role of multiparametric US and MR imaging.

Background: The 6-minute walking test (6mWT) is used to prescribe physical activity in cardiac surgery patients. The clinical value of a pre-discharge 6mWT and its association with outcome is not well defined. Design and methods: We retrospectively analyzed data from 313 patients (age 66 ± 11 years, 23% females, left ventricular ejection fraction (LVEF) 52 ± 11%, Hb 10.5 ± 1.3 g/dl, serum albumin 3.9 ± 0.4 mg/dl) who were admitted to our rehabilitation institute following cardiac surgery. A 6mWTwas performed at entry and at discharge and expressed as % of theoretical predicted values calculated on the basis of individual age, height, weight and sex. The endpoint was represented by all-cause mortality. The predictive value of 6mWT was tested in univariate and multivariate analysis. Results: A pre-discharge 6mWT was completed by 284 out of 313 patients. Two patients died in hospital. During a median of 23 months, mortality was 9% (26/284) and 44% (12/27) (p < 0.0001) in patients who did or did not perform the pre-discharge 6mWT. The distance covered at the pre-discharge 6mWT as a continuous variable of % predicted values was a significant predictor of subsequent mortality (Hazard Ratio (HR) 0.97 (95% CI 0.96-0.99), p = 0.0019). After adjustment for all preselected covariates, the pre-discharge 6mWT (HR 0.97 (95% CI 0.95-0.99), p = 0.0038) and LVEF (HR 0.93 (95% CI 0.90-0.96), p < 0.0001) remained significantly associated with the outcome. Conclusions: In recent cardiac surgery patients, the pre-discharge 6mWT is not only a valid measurement of the impact of cardiac rehabilitation but also provides outcome information offering the possibility to identify patients who may need more intensive follow-up. © The European Society of Cardiology 2013.

Objectives: The purpose of this study is to assess the effectiveness of defibrillation testing (DT) in patients undergoing implantable cardioverter-defibrillator (ICD) insertion. Background: Although DT is considered a standard procedure during ICD implantation, its usefulness has not been definitively proven. Methods: The SAFE-ICD (Safety of Two Strategies of ICD Management at Implantation) study is a prospective observational study designed to evaluate the outcome of 2 strategies: performing defibrillation testing (DT+) versus not performing defibrillation testing (DT-) during de novo ICD implants. No deviation from the centers' current practice was introduced. In all, 2,120 consecutive patients (836 DT+ and 1,284 DT-) age <18 years were enrolled at 41 Italian centers from April 2008 to May 2009 and followed up for 24 months until June 2011. The primary endpoint was a composite of severe complications at ICD implant and sudden cardiac death or resuscitation at 2 years. Results: The primary endpoint occurred in 34 patients: 12 intraoperative complications (8 in DT+ group; 4 in DT- group) and 22 during follow-up (10 in DT+ group; 12 in DT- group). Overall, the estimated yearly incidence (95% confidence interval) was DT+ 1.15% (0.73 to 1.83) and DT- 0.68% (0.42 to 1.12). The difference between the 2 groups was negligible: 0.47% per year (-0.15 to 1.10). Mortality from any cause was similar at 2 years (adjusted hazard ratio: 0.97 [0.76 to 1.23], p = 0.80). Conclusions: In this large cohort of new ICD implants, event rates were similar and extremely low in both groups. These data indicate a limited clinical relevance for DT testing, thus supporting a strategy of omitting DT during an ICD implant.

BACKGROUND: BEACOPP, an intensified regimen consisting of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, has been advocated as the new standard of treatment for advanced Hodgkin's lymphoma, in place of the combination of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). METHODS: We randomly assigned 331 patients with previously untreated and unfavorable Hodgkin's lymphoma (stage IIB, III, or IV, or an international prognostic score of ≥3 on a scale of 0 to 7, with higher scores indicating increased risk), to receive either BEACOPP or ABVD, each followed by local radiotherapy when indicated. Patients with residual or progressive disease after the initial therapy were to be treated according to a state-of-the-art high-dose salvage program. The median follow-up period was 61 months. RESULTS: The 7-year rate of freedom from first progression was 85% among patients who had received initial treatment with BEACOPP and 73% among those who had received initial treatment with ABVD (P = 0.004), and the 7-year rate of event-free survival was 78% and 71%, respectively (P = 0.15). A total of 65 patients (20 in the BEACOPP group, and 45 in the ABVD group) went on to receive the intended high-dose salvage regimen. As of the cutoff date, 3 of the 20 patients in the BEACOPP group and 15 of the 45 in the ABVD group who had had progressive disease or relapse after the initial therapy were alive and free of disease. After completion of the overall planned treatment, including salvage therapy, the 7-year rate of freedom from a second progression was 88% in the BEACOPP group and 82% in the ABVD group (P = 0.12), and the 7-year rate of overall survival was 89% and 84%, respectively (P = 0.39). Severe adverse events occurred more frequently in the BEACOPP group than in the ABVD group. CONCLUSIONS: Treatment with BEACOPP, as compared with ABVD, resulted in better initial tumor control, but the long-term clinical outcome did not differ significantly between the two regimens.

Interest in the numerous benefits of corticosteroid medication in the management of rheumatoid arthritis (RA) goes back to the mid-1950s, and has recently been renewed. The established evidence of their rapid symptomatic effects, along with the growing recognition of their long-lasting disease-modifying properties and preliminary data about their sub-clinical action, led us to reconsider the potential of corticosteroids in the treatment of RA, given their acceptable safety profile, especially when used at low dosages. Over time, several corticosteroid-based therapeutic approaches have been explored in order to optimize their clinical benefits, while limiting the adverse effects. Clinical data reported with initial high-dosage corticosteroid schedules with subsequent step-down schemes suggest clinical efficacy, but are not applicable to patient management in a real-life setting. Encouraging results on the clinical and sub-clinical effects of low dosages have led to a shift in usual daily practice. We present past and recent efforts to clarify the role of corticosteroids in the treatment of RA, focusing on the best approach in terms of dose and timing of corticosteroid administration. Additional information about different routes of administration, step-down schedules and adverse effects are also considered. © 2013 Springer International Publishing Switzerland.

Early invasive management and the use of combined antithrombotic therapies have decreased the risk of recurrent ischaemia in patients with acute coronary syndrome (ACS) but have also increased the bleeding risk. Transradial intervention (TRI) and bivalirudin infusion compared to transfemoral intervention (TFI) or unfractionated heparin (UFH) plus glycoprotein IIb/IIIa inhibitors (GPI) decrease bleeding complications in patients with ACS. To what extent, a bleeding preventive strategy incorporating at least one of these two treatment options translates into improved outcomes is a matter of debate. The Minimizing Adverse Haemorrhagic Events by Transradial Access Site and Systemic Implementation of AngioX study is a large-scale, multicenter, prospective, open-label trial, conducted at approximately 100 sites in Europe aiming to primarily assess whether TRI and bivalirudin infusion, as compared to TFI and UFH plus provisional GPI, decrease the 30-day incidence of death, myocardial infarction or stroke across the whole spectrum of ACS patients. © 2014 Springer Science+Business Media New York.

Time-average proteinuria (TAp) is the strongest predictor of renal survival in IgA nephropathy (IgAN). Little is known about the utility and safety of corticosteroids (CS) to obtain TAp<1 g/d in patients with advanced IgAN. This study sought to evaluate TAp at different degree of baseline renal function and histologic severity during CS use and to investigate treatment safety.We performed one-stage individual-patient data meta-analysis among 325 patients with IgAN enrolled in three prospective, randomized clinical trials. Patients were divided into three groups according to treatment: no treatment (NT; supportive therapy), CS, and CS plus azathioprine (CS+A). Associations of TAp with histologic grading, treatment, and eGFR at baseline were performed with linear regression models for repeated measures. The median follow-up duration was 66.6 months (range, 12-144 months).In the first 6 months, proteinuria did not change in the NT group and decreased substantially in the other groups(CS: from a meanSD of 2.201.0 to 0.8 [interquartile range, 0.4-1.2] g/d; CS+A: from 2.8762.1 to 1.0 [interquartile range, 0.5-1.7] g/d), independent of the degree of histologic damage and baseline eGFR. The percentage of patients who maintained TAp<1 g/d was 30.2% in the NT, 67.3% in the CS, and 66.6% in the CS+A group. Thirty-four patients experienced adverse events: none in the NT, 11 (6.4%) in the CS, and 23 (20.7%) in the CS+A group. The risk of developing adverse events increased with decreasing levels of eGFR (from 2.3% to 15.4%). The addition of azathioprine to CS further increased the percentage of patients with adverse events (16.8% versus 5.7% in study 2 and 30.0% versus 15.4% in study 3; overall P<0.001).In patients with IgAN, CS can reduce proteinuria and increase the possibility of maintaining TAp<1 g/d, regardless of the stage of CKD and the histologic damage. The risk of major adverse events is low in patients with normal renal function but increases in those with impaired renal function and with the addition of azathioprine.

Bing-Neel syndrome (BNS) is a rare complication seen in patients with Waldenstrm macroglobulinaemia (WM), in which lymphoplasmacytic lymphoma cells colonize the central nervous system. In this retrospective multi-centre study, we present the clinicopathological features, imaging findings, therapy, response and outcomes of 34 patients with BNS. The median time from WM diagnosis to BNS diagnosis was 3 years, 15% of patients were diagnosed with BNS at the time of WM diagnosis, and 22% of patients developed BNS when responding to active treatment for WM. Patients with BNS presented with variable clinical features including limb motor deficits, change in mental status and cranial nerve palsies. The diagnosis was made using a combination of cerebrospinal fluid cytology, flow cytometry and detection of the MYD88 L265 mutation, and magnetic resonance imaging. The estimated 3-year overall survival rate was 59%. Of the survivors, 40% have evidence of pathological and/or radiological persistence of disease. Age older than 65 years, platelet count lower than 100 10(9) /l, and treatment for WM prior to BNS diagnosis were associated with worse outcome. Exposure to rituximab for treatment of BNS was associated with a better outcome. Multi-institutional collaboration is warranted to improve treatment and outcomes in patients with BNS.

Acquired chromosomal abnormalities are important prognostic factors in patients with myelodysplastic syndromes treated with supportive care and with disease-modifying therapeutic interventions, including allogeneic hematopoietic stem cell transplantation. To assess the prognostic impact of cytogenetic characteristics after hematopoietic stem cell transplantation accurately, we investigated a homogeneous group of 523 patients with primary myelodysplastic syndromes who have received stem cells from human leukocyte antigen-identical siblings. Overall survival at five years from transplantation in good, intermediate, and poor cytogenetic risk groups according to the International Prognostic Scoring System was 48%, 45% and 30%, respectively (P<0.01). Both the disease status (complete remission vs. not in complete remission) and the morphological classification at transplant in the untreated patients were significantly associated with probability of overall survival and relapse-free survival (P<0.01). The cytogenetic risk groups have no prognostic impact in untreated patients with refractory anemia ± ringed sideroblasts (P=0.90). However, combining the good and intermediate cytogenetic risk groups and comparing them to the poor-risk group showed within the other three disease-status-at-transplant groups a hazard ratio of 1.86 (95%CI: 1.41-2.45). In conclusion, this study shows that, in a large series of patients with primary myelodysplastic syndromes, poor-risk cytogenetics as defined by the standard International Prognostic Scoring System is associated with a relatively poor survival after allogeneic stem cell transplantation from human leukocyte antigen-identical siblings except in patients who are transplanted in refractory anemia/refractory anemia with ringed sideroblasts stage before progression to higher myelodysplastic syndrome stages. © 2014 Ferrata Storti Foundation.
