Abstract
In this work, we evaluated the performance of the prototype SFOV MediPROBE developed at the University of Naples Federico II through the protocol proposed by (Bhatia B.S., Bugby S.L., Lees J.E., Perkins A.C. A scheme for assessing the performance characteristics of a small field of-view gamma cameras. Physica. Medica., 31 (1), pp. 98-103. (2015) doi: 10.1016/j.ejmp.2014.08.004). We extensively investigated a new device configuration where the pinhole collimator was placed outside the housing of the probe, in order to increase the system spatial resolution, and the pixel size was doubled, in order to reduce the charge sharing effect. The experimental measurements show that the spatial resolution is enhanced by only about 10%, but the sensitivity decreases strongly. Therefore, the trade-off between these two features does not seem to be advantageous. In addition, our experiments suggest that the charge sharing effect is not completely canceled. Despite these results, the features of this device appear suitable for intraoperative surgical survey. We aim to use this device in the clinical practice for the intraoperative imaging of lymph nodes, breast, thyroid and parathyroid tumors.

Abstract
INTRODUCTION Increased levels of cardiac troponins (cTn) are a hallmark of acute myocardial infarction (AMI), along with symptoms and electrocardiographic (ECG) changes. Stably elevated cTn concentrations are frequently observed in asymptomatic patients with chronic kidney disease (CKD) and/or on hemodialysis (HD); the meaning of this elevation, as assessed by conventional techniques, remains unclear. Aim of our study was to evaluate the clinical significance of cTnI levels in asymptomatic HD patients by employing a newer high-sensitive cTnI (hs-cTnI) assay. METHODS We enrolled 49 patients undergoing regular HD treatment for more than 3 months; all patients were asymptomatic for chest pain and had no history of acute coronary syndrome in the past 2 months. For every patient we measured hs-cTnI, cTnI and brain natriuretic peptide (BNP) before initiation of one HD session at baseline (T0), after 3 (T1) and 9 months (T2). Demographic, anamnestic, dialytic and echocardiographic characteristics of the examined population were evaluated. We also recorded the number of cardiovascular events from T0 to 12 months after T2. RESULTS Fifteen patients were lost to follow-up: 6 died, 2 underwent kidney transplantation, 7 did not match the inclusion criteria later during observation. At T0 (49 patients) we observed 14 hs-cTnI positive patients vs. 4 standard c-TnI positive patients (28,5% vs 8,1%); at T1 (40 patients) 16 vs 3 (26.4% vs 7.5%); at T2 (34 pz) 9 vs 0 (26.4% vs 0%). During the study we recorded 10 cardiovascular events, 8 of which in patients that were hs-cTNI positive, leading to death in 3. Hs-cTnI levels were predictive of cardiovascular events at all times and predictive of cardiovascular mortality at T0 and T1 (p < 0.001). In a multivariate analysis, a history of coronary artery disease (CAD) was an independent variable of high hs-cTnI levels at T0 (p < 0.04) and T1 (p < 0.03). CONCLUSIONS Our study shows that a novel sensitive assay detects more asymptomatic HD patients compared to previously used methods, being at the same time predictive of cardiovascular mortality and morbidity. The only independent variable of high hs-cTnI concentrations was a positive history of cardiovascular disease, suggesting a possible role of hs-cTnI in identifying a high-risk subset of patients.

Abstract
BACKGROUND Comparing the prognostic value of a negative finding by stress single-photon emission computed tomography myocardial perfusion imaging (MPI) and coronary computed tomography angiography (CCTA) may be useful to evaluate how better identify low-risk patients. We performed a meta-analysis to compare the long-term negative predictive value (NPV) of normal stress MPI and normal CCTA in subjects with suspected coronary artery disease (CAD). METHODS AND RESULTS Studies published between January 2000 and November 2016 were identified by database search. We included MPI and CCTA studies that followed-up ≥100 subjects for ≥5 years and providing data on clinical outcome for patients with negative tests. Summary risk estimates for normal perfusion at MPI or <50% coronary stenosis at CCTA were derived in random effect regression analysis, and causes of heterogeneity were determined in meta-regression analysis. We identified 12 eligible articles (6 MPI and 6 CCTA) including 33,129 patients (26,757 in MPI and 6372 in CCTA studies) with suspected CAD. The pooled annualized event rate (AER) for occurrence of hard events (death and nonfatal myocardial infarction) was 1.06 (95% confidence interval, CI 0.49-1.64) in MPI and 0.61 (95% CI 0.35-0.86) in CCTA studies. The pooled NPV was 91% (95% CI 86-96) in MPI and 96 (95% CI 95-98) in CCTA studies. The summary rates between MPI and CCTA were not statistically different. At meta-regression analysis, no significant association between AER and clinical and demographical variables considered was found for overall studies. CONCLUSIONS Stress MPI and CCTA have a similar ability to identify low-risk patients with suspected CAD.

Abstract
BACKGROUND/AIMS Multiple myeloma (MM) represents 10% of all haematologic malignancies. Renal involvement occurs in 50% of MM patients; of them, 12-20% have acute kidney injury (AKI), with 10% needing dialysis at presentation. While hemodialysis (HD) has no effect upon circulating and tissue levels of monoclonal proteins, novel apheretic techniques aim at removing the paraproteins responsible for glomerular/tubular deposition disease. High cut-off HD (HCO-HD) combined with chemotherapy affords a sustained reduction of serum free light chains (FLC) levels. One alternative technology is haemodiafiltration with ultrafiltrate regeneration by adsorption on resin (HFR-SUPRA), employing a "super high-flux" membrane (polyphenylene S-HF, with a nominal cut-off of 42 kD). Aim of our pilot study was to analyze the effectiveness of HFR-SUPRA in reducing the burden of FLC, while minimizing albumin loss and hastening recovery of renal function in 6 subjects with MM complicated by AKI. METHODS Six HD-dependent patients with MM were treated with 5 consecutive sessions of HFR-SUPRA on a Bellco® monitor, while simultaneously initiating chemotherapy. Levels of albumin and FLC were assessed, calculating the rates of reduction. Renal outcome, HD withdrawal and clinical follow-up or death were recorded. RESULTS All patients showed a significant reduction of FLC, whereas serum albumin concentration remained unchanged. In three, HD was withdrawn, switching to a chemotherapy alone regimen. The other patients remained HD-dependent and died shortly thereafter for cardiovascular complications. CONCLUSION Our study suggests that HFR-SUPRA provides a rapid and effective reduction in serum FLC in patients with MM and AKI, while minimizing the loss of albumin. When started early in combination with chemotherapy, blood purification by HFR-SUPRA was followed by the recovery of renal function in half of the patients treated.

Abstract
OBJECTIVES Despite universal infection control precautions, the risk of hepatitis B virus (HBV) infection in patients on chronic haemodialysis (HD) remains high. For this reason anti-HBV vaccination is recommended in these subjects. In hemodialyzed patients vaccinal response is often suboptimal and it's not clear what factors may influence it. STUDY DESIGN The aim of our study is to assess the influence of some clinical and laboratory factors on seroconversion rate after anti HBV vaccination in a cohort of patients on maintenance HD. METHODS We analysed 60 patients on regular HD, 40 men and 20 women (age 64±12 years, range 40-88 years), immunized with Engerix B ® vaccine, followed for an average time of 62 month (12-120 months). For each patient the following data were collected: age, serum albumin (sAlb), Blood urea nitrogen before HD session (BUN), age at vaccination, dialysis vintage, presence of systemic disease, type of vascular access, dialysis modality. Correlation between these factors and anti Hbs titer was estimated with multiple regression analysis. RESULTS Anti-Hbs seroconversion rate ( Anti Hbs > 10 IU/l) was 77%. Better rate of seroconversion (86%) was observed in patients with arteriovenous fistula (AVF) and serum albumin > 3,5 g/dL (93%), while higher rate of not responders (50%) in patients with systemic diseases. The only parameter correlated to anti Hbs titer was sAlb (p =0,0012). sAlb was correlated to age in all patients (p=0,01) and age was correlated to higher anti Hbs titer in the responder group (p=0,018). DISCUSSION In our experience an early vaccination, when patients on chronic HD are younger and in better nutritional conditions, improves anti-HBV response.

Abstract
BACKGROUND Oxidative stress has been related to hypo-response to erythropoiesis-stimulating agents (ESAs) in hemodialysis (HD) patients. The aim of this study was to verify whether vitamin E (ViE) on a synthetic polysulfone dialyzer can improve ESA responsiveness. METHODS This controlled, multicenter study involved 93 HD patients on stable ESA therapy, who were randomized to either ViE-coated polysulfone dialyzer or to a low-flux synthetic dialyzer. The primary outcome measure was the change in ESA resistance index (ERI) from baseline. RESULTS Mean ERI decreased in the ViE group by 1.45 IU/kg*g/dl and increased in the control group by 0.53 IU/kg*g/dl, with a mean difference of 1.98 IU/kg*g/dl (p = 0.001 after adjusting for baseline ERI, as foreseen by the study protocol). Baseline ERI was inversely related to its changes during follow-up only in the control group (R2 = 0.29). CONCLUSIONS The ViE dialyzer can improve ESA response in HD patients. Changes in ERI during follow-up are independent from baseline ERI only in the ViE group. Video Journal Club 'Cappuccino with Claudio Ronco' at http://www.karger.com/?doi=453442.

Abstract
This study compares 5 different tidal automated peritoneal dialysis (APD) prescriptions. Six low-average and 6 high-average transporters performed 3 separate sessions with 5 different schedules: (A) 50% tidal with initial fill volume (FV) 2 liters, (B) 50% tidal with 2.2 liters initial FV, (C) 2.2 liters initial FV with 70% tidal, (D) as in B, with one complete renewal of the initial FV at midsession, (E) 2.2 liters FV with breakpoint modality. Urea, creatinine and phosphate peritoneal clearances, sodium removal and ultrafiltration (UF) were compared using analysis of variance. Compared to treatment A, all the tested alternative schedules were associated with 10% significantly higher urea clearance; B, D and E, but not C, were associated with 10% higher creatinine clearance. Phosphate clearance was significantly higher with D, while sodium removal was larger with both C and D. UF was lower with A and E in high average transporters. Manipulation of the main prescriptive parameters of tidal APD has significant impact on its efficiency.

Abstract
Idiopathic retroperitoneal fibrosis (IRF) is a rare disease characterized by fibro-inflammatory reaction surrounding ureters and other inner organs with possible secondary renal involvement. Symptoms are aspecific and recurrent phases of activity are generally associated with elevation of inflammatory indices. 18F-FDG-PET is nowadays an important tool for the detection of this disease, allowing differentiation between metabolically active tissue and fibrotic one. The purpose of this study was to investigate the role of 18F-FDG-PET in the management of IRF and to evaluate possible correlations between biochemical parameters and PET/CT findings of disease activity. We enrolled seven consecutive patients with IRF (in five histology proved the disease) observed from 2003 to 2012 (5 M:2 F, mean age 53.8 years, range 44-86 years). All patients presented with fever as first symptom; two had obstructive renal failure requiring hemodialysis; one underwent monolateral nephrectomy for parenchyma infiltration; six presented ureteral involvement; three underwent ureteral stent placement. For each patient, during a mean total follow-up of 26.5 months we evaluated serum creatinine, BUN, Hb, RBCs, WBCs, PLT, CRP, ESR. Periodic 18F-FDG-PET/CT scans (every 5.9 months-mean) were performed in all patients. Statistical evaluation was performed using "stepwise regression" analysis. Steroids and immunosuppressive agents induced a progressive normalization of PET/CT scans in all patients at the end of follow-up. Stepwise regression analysis showed that BUN, serum creatinine and CRP only if considered together, significantly correlated with SUV max (p value = 0.000003057). 18F-FDG-PET is a useful tool for clinical decision making in patient with IRF, allowing to evaluate the efficacy of the pharmacological treatment and to detect early recurrences, to modify the therapeutic approach. Acute phase reactants are not reliable alone for the management and the follow-up as they are often not concordant with metabolic assessment of the disease. In patients with ureteral involvement, CRP together with BUN and serum creatinine has a significant correlation with PET/CT results, and can help physicians in therapeutic approach, better than a single parameter.

Abstract
BACKGROUND AND AIMS In elderly subjects, renal insufficiency and osteoporosis often coexist with high risk of fracture and elevated socio-economic burden. Today a large number of effective anti-osteoporotic drugs are available but generally they are contraindicated in patients with chronic kidney disease (CKD) because of their progressive accumulation. Denosumab, instead, does not require dose adjustments for different degrees of renal impairment so it can be a valid treatment in osteoporotic patients with CKD. Limited data are available in the literature concerning the use of denosumab in hemodialysis (HD). The aim of our study was, therefore, to study the efficacy and tolerability of this drug in this particular subset of patients. METHODS We retrospectively reviewed the charts of 12 osteoporotic HD patients who received a single 60-mg subcutaneous dose of denosumab every 6 months for an observation period of 24 months. Serum electrolyte, markers of bone turnover and quantitative ultrasound (QUS) were evaluated. RESULTS Over 24 months, we observed a gradual improvement of bone metabolism: β-CrossLaps from 2567.08 ± 1264 to 1492.5 ± 1182.5 pg/ml; bone alkaline phosphatase (BALP) from 33.5 ± 28.8 to 11.8 ± 3.7 mcg/l, and of QUS index (T-score from -5.33 ± 1.58 to -4.84 ± 1.2; risk of fracture from 13.9 ± 4.7 to 11.07 ± 5.3 %). Few cases of hypocalcemia were detected, more significant after the first and second injection, but with careful monitoring of serum calcium and rapid therapy adjustment we could easily manage serum Ca levels. CONCLUSIONS Our pilot experience highlights the safety and efficacy of denosumab in the treatment of osteoporosis in HD patients, potentially supporting its use to reduce the burden of fractures in this patient population.

Abstract
Metformin (MF) accumulation during acute kidney injury is associated with high anion gap lactic acidosis type B (MF-associated lactic acidosis, MALA), a serious medical condition leading to high mortality. Despite dose adjustment for renal failure, diabetic patients with chronic kidney disease (CKD) stage III-IV are at risk for rapid decline in renal function by whatever reason, so that MF toxicity might arise if the drug is not timely withdrawn. Sixteen consecutive patients were admitted to our Hospital's Emergency Department with clinical findings consistent with MALA. Fifteen had prior history of CKD, 60 % of them with GFR between 30 and 60 ml/min. Of these, 5 required mechanical ventilation and cardiovascular support; 3 promptly recovered renal function after rehydration, whereas 10 (62 %) required continuous veno-venous renal replacement treatment. SOFA and SAPS II scores were significantly related to the degree of lactic acidosis. In addition, lactate levels were relevant to therapeutic choices, since they were higher in dialyzed patients than in those on conservative treatment (11.92 mmol/l vs 5.7 mmol/l, p = 0.03). The overall death rate has been 31 %, with poorer prognosis for worse acidemia, as serum pH was significantly lower in non-survivors (pH 6.96 vs 7.16, p > 0.04). Our own data and a review of the literature suggest that aged, hemodynamically frail patients, with several comorbidities and CKD, are at greater risk of MALA, despite MF dosage adjustment. Moreover, renal replacement therapy rather than simple acidosis correction by administration of alkali seems the treatment of choice, based on eventual renal recovery and overall outcome.

Abstract
BACKGROUND The prognostic value of normal stress myocardial perfusion single-photon emission computed tomography (MPS) in patients with diabetes has only been evaluated in single-center studies of relatively limited sample size. We performed a meta-analysis of published studies, including diabetic patients with known or suspected coronary artery disease (CAD), to assess the predictive value for adverse cardiac ischemic events of normal stress MPS. METHODS AND RESULTS Studies published between January 1990 and December 2013 were identified by database search. We included studies using stress MPS to evaluate diabetic patients with known or suspected CAD and providing data on clinical outcomes of non-fatal myocardial infarction or cardiac death with a follow-up time ≥12 months. A total of 14 studies were finally included, recruiting 13,493 patients. The negative predictive value (NPV) for non-fatal myocardial infarction and cardiac death of normal MPS was 94.92% (95% confidence interval 93.67-96.05), during a weighted mean follow-up of 36.24 months, resulting in estimated event rate after a negative test equal to 5.08% (95% confidence interval 3.95-6.33). The corresponding annualized event rate after a negative test was 1.60% (95% confidence interval 1.21-2.04). CONCLUSIONS Stress MPS has a high NPV for adverse cardiac events in diabetic patients with known or suspected CAD leading to define a "relatively low-risk" patients category.

Abstract
The Drosophila trp homologue Transient Receptor Potential (TRP) cation channels are ubiquitous in most species and cell types. The functional TRP subclasses TRPC, TRPV and TRPP gate Ca2+ and other cations in mammalian tissues, including the kidney. It is now clear that TRP channels play an important role in renal physiology and in certain genetic disorders of the kidney. Hence, there is considerable interest in targeting mutated or dysfunctional TRP channels in an effort to treat such diseases. Transcellular epithelial cell Ca2+ reabsorption occurs in the distal tubule via luminal TRPV5/V6 channels. Indeed, TRPV5 KO mice display phenotypic defects of renal disease, including hypercalciuria and impaired bone mineral density. Similar to Ca2+, Mg2+ transcellular reabsorption occurs in the distal convoluted tubule via apical TRPM6/TRPM7 channels. TRPC6 is a component of the glomerular podocyte "slit diaphragm" and its autosomic dominant mutation has been linked to a familial, steroid-resistant form of nephrotic syndrome. A more common inherited disorder of the tubular epithelium, autosomal dominant polycystic kidney disease (ADPKD), is at least in part related to mutation of polycystin 2 (PC2), a protein encoded by the PKD2 gene. PC2 is now identified as TRPP2, a Ca(2+)-permeable non-selective cation channel located on the cilia of tubular epithelial cells. TRP-related ion transport may also play a role in the pathogenesis of arterial systemic and/or pulmonary hypertension through regulation of vascular smooth muscle contraction, renal perfusion/hemodynamics, as well as the total body balance of divalent cations. Thus, multiple renal TRP channels are potential targets for pharmacological intervention aimed at preventing or attenuating the burden of chronic kidney disease.

Abstract
In a comprehensive evaluation of dialysis adequacy, major attention has been recently paid to fluid and Na balance. Removal of Na has been reported to be significantly poorer with automated peritoneal dialysis (APD) than with continuous ambulatory peritoneal dialysis. Only limited data on Na removal with tidal APD have been published. We analyzed peritoneal Na mass balance in 122 separate nightly tidal APD sessions performed by 7 peritonitis-free, clinically stable, patients with negligible residual renal function (< 100 mL urine daily). Correlations with other efficiency measures [ultrafiltration (UF) and small-solute clearances], prescriptive parameters [duration of treatment, initial intraperitoneal fill volume (IPV) and its tidal percentage, and dialysate flux] and peritoneal transport status were tested in univariate and multivariate linear regression models. Removal of Na was 89 +/- 55 mmol per treatment, which correlated with UF (r = 0.29, p = 0.001) and was higher in patients with high-average transport (118 +/- 41 mmol vs. 81 +/- 56 mmol in low-average transporters, p = 0.0004), in whom a significant positive correlation was found with initial IPV and duration of treatment (r = 0.55; 95% confidence interval: 0.21 to 0.77; p = 0.0029; and r = 0.66; 95% confidence interval: 0.38 to 0.83; p = 0.0002 respectively). Removal of Na correlated weakly with UF in tidal APD and showed wide inter-patient variability. It should therefore be measured rather than roughly estimated from UF. Its magnitude exposes the anuric patient on nightly APD with a "dry" day to the risk of Na retention, unless controlled Na intake or dialytic strategies aimed at enhancing Na removal, or both, are implemented.

Abstract
During a retroperitoneoscopic adrenalectomy in the prone position, a sudden increase in end-Tidal CO2 (EtCO2) (from 42 to 68 mmHg) followed by an abrupt decrease (from 68 to 35 mmHg) was observed, concomitantly with a right adrenal vein laceration. Heart rate decreased to 30 bpm, and the systolic blood pressure decreased to 40 mmHg. The patient was slightly turned in the left lateral and Trendelenburg position and vasoactive drugs were administered. The systemic blood pressure, EtCO2, CO2 elimination (VCO2) and pulse oximetry (SpO2) progressively improved within 10 minutes and, at the end of the surgery, the blood pressure recovered from hypotension. ECG returned to normal, with sinusal rhythm and heart rate approximately 70 bpm. The patient was extubated and moved to the Intensive Care Unit (ICU). This case suggests that gas embolisms may occur during retroperitoneoscopic adrenalectomy, and acute changes in EtCO2 should alert the clinicians to these rare but potentially lethal complication. EtCO2 monitoring is essential during laparoscopy, as it may help an early detection of CO2 embolism, characterized by a transient and rapid increase in EtCO2, followed by an abrupt decrease.

Abstract
Background. The value of incremental peritoneal dialysis (PD) as a bridge to renal transplantation (Tx) has not been specifically addressed. Methods. All consecutive Stage 5 CKD patients with at least 1 year predialysis followup, starting incremental PD or HD under our care and subsequently receiving their first renal Tx were included in this observational cohort study. Age, gender, BMI, underlying nephropathy, residual renal function (RRF) loss rate before dialysis and RRF at RRT start, comorbidity, RRT schedules and adequacy measures, dialysis-related morbidity, Tx waiting time, RRF at Tx, incidence of delayed graft function (DGF), in-hospital stay for Tx, serum creatinine at discharge and one year later were collected and compared between patients on incremental PD or HD before Tx. Results. Seventeen patients on incremental PD and 24 on HD received their first renal Tx during the study period. Age, underlying nephropathy, RRF loss rate in predialysis, RRF at the start of RRT and comorbidity did not differ significantly. While on dialysis, patients on PD had significantly lower epoetin requirements, serum phosphate, calciumxphosphate product and better RRF preservation. Delayed graft function (DGF) occurred in 12 patients (29%), 1 on incremental PD and 11 on HD. Serum creatinine at discharge and 1 year later was significantly higher in patients who had been on HD. Conclusions. In patients receiving their first renal Tx, previous incremental PD was associated with low morbidity, excellent preservation of RRF, easier attainment of adequacy targets and significantly better immediate and 1-year graft function than those observed in otherwise well-matched patients previously treated with HD.

Abstract
The classification and management of hypertensive crisis have been recently reviewed in the context of both European and American guidelines. The key points for proper blood pressure control in severe arterial hypertension are: 1 - Distinction between urgent intervention and emergencies 2 - Choice of the best drug(s) 3 - Choice of the correct route of administration. In patients with renal disease, beside the common causes of hypertension/ hypertensive crises, kidney-specific causes should be taken into account such as renal parenchymal hypertension, renovascular hypertension, sclerodermic crises, and preeclampsia.

Abstract
Abstract
Aim: In patients treated for localized breast cancer, incidence, localization, and time of recurrences were registered and analyzed with the purpose of defining possible differences in site and /or time of failures associated with triple negative histology (ER-, PgR-, ERB-B2-) .
Patients and Methods: Five hundred eighty five consecutive female patients affected by localized breast cancer treated at our department between January 1999 and December 2006 were considered. Median age was 53 years (range 27 − 84). Firty five (7.9%) patients were at Stage 0 of disease, 272 (47.6%) Stage I, 206 (36%) Stage II, and 49 (8.5%) Stage III. Fifty nine (13.5%) of 440 assessable patients resulted triple negative. All patients were treated by surgery (breast sparing 552 (94.4%), mastectomy 33 (5.6%)) plus postoperative radiation therapy at doses of 50 Gy in 5 weeks, on the breast or thoracic wall and nodal regions, plus, in the case of breast conserving surgery, 10 Gy in a week on the tumoral bed. Chemotherapy, hormonal therapy or both was administered to 170, 168 and 161 patients respectively. Time and localization of recurrences were registered and analyzed relatively to the whole population and triple negative status.
Results: At a median follow up of 61 months (range 3-137) 18 (3.1%) local and 41 (7.0%) distant relapses were registered. Thirty one (5.3%) patients died of which 23 (3.9%) for breast cancer. Sites of first distant metastasis detection were bone (25%), liver (17%), lung (15%), brain (8%). In 34% of cases the detection of metastatic disease at exordium was represented by the contemporary appearance of multiple organ involvement. The median time to distant metastasis relapse resulted 34 months (range 8 − 117) with 88% of relapses before 60 months for the whole group. However in the triple negative subgroup the rate of distant relapse resulted 13.5% and local relapse 5.1%. Median time to distant relapse was 25 (8 − 48) months. Locoregional relapses were mostly in the breast or thoracic wall (16, 89%), with fewer nodal relapses (2, 11%). The median time to locoregional relapse was 32 months (8 − 78) with 78% of relapse before than 60 months and no differences were found in the patterns of relapse between the groups.
Conclusions: In our experience localized breast cancer distal recurrences mostly involves primarily bone, liver, and lung with about one third of patients having multiple organ metastatic exordium. In triple negative subgroup there was an increased risk of distant relapse with a shorter median time. No difference in time and site patterns were found relatively to locoregional recurrences.

Abstract
BACKGROUND While chronic dialysis treatment has been suggested to increase pulmonary pressure values, right ventricular dysfunction (RVD) is a major cause of death in patients with end-stage renal disease. We investigated the impact of different dialysis treatments on right ventricular function. METHODS We examined 220 subjects grouped as follows: healthy controls (n = 100), peritoneal dialysis (PD; n = 26), hemodialysis (HD) with radial arteriovenous fistula (AVF; n = 62), and HD with brachial AVF (n = 32). Echocardiography including tissue Doppler imaging (TDI) of the right ventricle was performed in all patients. RESULTS Pulmonary pressure values progressively rose from controls across the 3 dialysis groups (21.7 ± 6.8, 29.7 ± 6.7, 37.9 ± 6.7 and 40.8 ± 6.6 mm Hg, respectively; p < 0.001). TDI indices of right ventricular function were more impaired in HD patients, particularly in those with brachial AVF. RVD, assessed by TDI myocardial performance index, was higher in HD patients compared with PD patients (71.3 vs. 34.6%, p < 0.001). Moreover, the prevalence of RVD further increased in patients with brachial AVF compared with the radial access (90.6 vs. 61.3%, p < 0.001). CONCLUSIONS Compared to DP, HD increases the risk of RVD, particularly in the presence of brachial AVF. TDI may detect early functional failure of the right ventricle in HD patients.

Abstract
Background Primary orbital lymphoma is a rare disease that accounts for 10% of all orbital tumors. Radiotherapy on the orbital cavity is the treatment of choice for this unusual presentation of localized non-Hodgkin's lymphoma (NHL). The aim of this study is to retrospectively evaluate the effectiveness and the toxicity of radiation treatment in patients with primary orbital lymphoma. Methods Forty-seven consecutive patients having primary orbital lymphoma treated in our department between May 1983 and September 2006 were investigated in a retrospective study. Either 60Co γ rays or 6 MV X rays were used to deliver daily fractions of 1.8 or 2.0 Gy, 5 times/week, with total doses ranging from 34.2 to 50 Gy. Forty-three patients had stage IE, three had stage II and one stage IV disease. Thirty-eight patients had marginal zone B-cell lymphoma, 5 diffuse large B cell lymphoma, 3 mantle cell lymphoma and 1 Burkitt lymphoma. Local control (LC), disease free survival (DFS), overall survival (OS) and late side effects were evaluated in all patients. Results With a median follow up of 45 months, LC was obtained in 100% of patients. The estimated 5- and 7-year DFS rates were 75.8% and 55.3%, and the 5- and 7-year OS rates were 88.7% and 79.9% respectively. Acute toxicity was minimal. Late toxicity such as cataract, keratitis, retinopathy and xerophthalmia occurred respectively in 12 (25.5%), 5 (10.6%), 1 (2.1%), and 9 (19.1%) patients. Conclusion Radiotherapy is an effective and at the same time well tolerated treatment for primary orbital lymphoma.

Abstract
BACKGROUND We evaluated the incremental prognostic value of viability assessment by nitrate single-photon emission computed tomography (SPECT) in patients with ischemic left ventricular (LV) dysfunction. METHODS AND RESULTS One hundred and sixty-four patients with previous myocardial infarction and LV dysfunction (ejection fraction 29% +/- 15%) underwent two Tc-99m sestamibi SPECT studies, under control conditions and after sublingual nitrate administration, for evaluation of myocardial viability. In each patient, viability was defined as the presence of > or = 2 severely dysfunctional segments with preserved tracer uptake (> or = 55% of peak activity). Cardiac death, myocardial infarction, and late (> 2 months) revascularization were considered events. Follow-up was 98% complete at a mean period of 30 +/- 24 months. At baseline SPECT, 119 (73%) patients had evidence of viable myocardium, while 45 (27%) did not. Of these latter patients, 18 (40%) had evidence of viability after nitrate administration. Cardiac events occurred in 58 (35%) patients. Cumulative probability of event-free survival was similar in patients with and without viability at baseline SPECT (log rank 0.3, P = NS), while it was lower in patients with viability at nitrate SPECT compared to those without (log rank 6.3, P < .01). The addition of nitrate SPECT data significantly improved the prognostic power of the model including clinical, functional, angiographic, and baseline SPECT data (P < .01). CONCLUSIONS In patients with previous myocardial infarction and LV dysfunction, nitrate SPECT imaging provides incremental prognostic information over those obtained from clinical, functional, angiographic variables, and baseline SPECT data.

Abstract
PURPOSE To measure chromosomal aberrations in blood lymphocytes from breast cancer patients treated with radiotherapy after quadrantectomy or tumorectomy. METHODS AND MATERIALS Twenty-two breast cancer patients treated with breast-conserving surgery and radiation were evaluated. Adjuvant chemotherapy was also given to 9 patients. Blood samples were obtained before radiotherapy, after about one-half of the fractions, and at the end of the treatment of the whole breast (50 Gy). Chromosome aberrations in peripheral blood lymphocytes were measured using chemical-induced premature chromosome condensation combined with fluorescence in situ hybridization. RESULTS Radiation treatment produced a significant increase in the yield of chromosomal aberrations. A large interindividual variability was observed. The variability was not related to field size, previous chemotherapy, or treatment morbidity. Chromosome aberrations in lymphocytes at the end of the treatment were significantly higher in the group of patients with no lymph nodes surgically removed before the treatment than in the group of patients with more than 10 lymph nodes removed. CONCLUSION The number of lymph nodes within the radiation field is an important factor affecting the yield of radiation-induced chromosomal aberrations in breast cancer patients.

Abstract
A significant change has occurred in the management of symptomatic benign prostatic hyperplasia (BPH) since effective pharmacological treatment became available and led to a significant decrease in the number of surgical procedures in many Western countries. The hypothesis of a causative role of benign prostatic enlargement and bladder outflow obstruction (BOO) in lower urinary tract symptoms (LUTS) was based on the association between prostate growth and symptoms of prostatism in elderly men and on the dramatic reduction of LUTS upon relief of obstruction. Careful investigation into the epidemiology of LUTS and BPH failed to confirm such an association and opened new perspectives in the pathophysiology of lower urinary tract dysfunction and symptoms. The observation that LUTS were equally distributed in male and female cohorts, when matched for age, moved attention away from the prostate and towards the urinary bladder and its aging-related disorders. When BPH surgery was developed, the management of the disease was aimed at preventing death from chronic renal failure, but the picture has changed and modern medical treatment is now aimed at improving the patient's quality of life. The increasing size of elderly populations in the Western world and the consequent financial constraints of national healthcare systems have raised the question of when pharmacological treatment of symptomatic BPH should be initiated. Retrospective and prospective analysis of various BPH populations and clinical studies has clearly defined the capacity of pharmacological treatment to reduce the incidence of complications of BPH, such as acute urinary retention and the need for surgery, but the cost/benefit ratio is unclear. Notwithstanding the limitations inherent in the experimental models, there is evidence from various animal models, investigating the pathophysiology of the urinary bladder in the presence of outflow obstruction, to indicate that a cause and effect relationship between BOO and bladder decompensation has been established and to support the hypothesis that permanent bladder damage may occur when the obstruction is not relieved early enough. Preliminary experimental evidence also suggests that alpha(1)-adrenoceptor antagonists may have a role in reducing the damaging effects of BOO on the urinary bladder. At present, there is no evidence to support the need for early pharmacological treatment of symptomatic BPH with no BOO beyond the obvious target of improving the patient's quality of life. The evidence for early treatment of BOO and the need to preserve bladder function is clear. Further experimental and clinical research is required to identify markers of early bladder damage and decompensation which can be used to select patients for early pharmacological treatment of BPH.

Abstract
BACKGROUND Erectile dysfunction is one of the factors influencing negatively the quality of life of patients in hemodialytic treatment. The international literature shows that erectile dysfunction is present in 30% of patients with chronic renal failure and in 50% of patients undergoing dialytic treatment. Fertility, libido and erectile dysfunction, suffer progressive worsening with time, in spite of hemodialysis. The availability of a drug like Sildenafil can improve the quality of life of the patient and give him a normal sexual activity. METHODS Twenty patients between 29 and 51 years, were selected; 2 of these had been subjected to renal transplant, with a dialytic treatment time varying from 3 to 13 years. Before the treatment all the patients have been subjected to an andrological screening (testosterone, prolactin, penile color Doppler ultrasound) and proposed the IIEF test. Therapeutic strategy included the assumption of the drug in the days in which the patients were not subjected to dialysis, with an interval from 1 to 3 weeks between assumption and another. The dose was 25-50 mg. At the end of three months of therapy the patients were again subjected to the IIEF test. RESULTS All patients reported an improvement in sexual activity and sexual desire with very good repercussions on general and psychophysical conditions. CONCLUSIONS The results demonstrate at least that Sildenafil is also effective in uremic patients in dialytic treatment or after renal transplant and that it can therefore resolve one of the main problems for the normal development of the life of such patients.

Abstract
The diagnosis of renal osteodystrophy is straightforward when the disease has reached an advanced stage and the pathology is extremely difficult to treat, whereas it is considerably more complex during the early stages. A study was carried out to assess the sensitivity of some biochemical, hormonal and instrumental markers in the early diagnosis of osteitis fibrosa in patients undergoing hemodialysis due to chronic renal insufficiency. Of these markers, the assay of whole molecule PTH appeared to be the most sensitive and specific biological marker.

Abstract
Traditional therapy for heart failure (diuretics, digitalic compound, vasodilators, inodilatory ACE-inhibitors) cannot arrest the progressive overloading of the circulatory system so that it is inevitable that a refractory stage to all forms of treatment will be reached when more specialised techniques, such as heart transplant and ultrafiltration will be needed. The paper reports the results obtained in 13 patients in ultrafiltration treatment for refractory heart failure: in the majority of these, a marked improvement in general conditions (edema, dyspnea) was recorded together with a regression from class 5 to class 3 NYHA in 5 patients, and to class 2 for others. The ultrafiltration method in spite of not altering the prognosis which remains negative in these patients, allow those waiting for heart transplant to survive and may improve their chances of surviving heart surgery.
