Abstract
BACKGROUND Scientific data from current literature demonstrate an incidence of bacteraemia due to tunnelled central venous catheter (tCVC) use accounting for 1.6 / 1000 days per tCVC, with a range of 1.5 to 1.8. In Sicily no data on the incidence of tCVC- related bacteraemia are available. In our hospital, tCVC infection occurs 2.4 times in 1000 days during CVC use. A retrospective analysis carried out from 2006 to 2012 was performed on 650 patients with tunnelled catheters. Of the subjects who received tCVC in our hospital, 90% were destined to undergo haemodialysis in a private health care environment outside our hospital. MATERIALS AND METHODS In order to improve the aforementioned infection outcome, we planned and implemented a specific work project. The work project (WP) was subdivided into two steps: 1) The first step was further subdivided into two sub-phases. The first was principally concerned with the implementation of educational courses, conducted directly on the ward and aimed at the implementation of meticulous nursing regimes for the care of tCVC by our health care nurse. The courses were entitled Management of Vascular Access: from doing - to teaching to do!. These educational courses were organized by the Nephrology Department, which takes care of the management and handling of the major complications of tCVCs for the maintenance of haemodialysis. After this first step, the nurses who had participated became the promoters of the second part of the course, which concerned the development of know-how within an outpatient clinic, which deals exclusively with the nursing management of tCVCs. 2) The title of the second phase was Therapeutic Education: self-Care and understanding and managing your venous access at home. The aim of this step was the integration of correct in-hospital care with that available in outsourced private institutions, via the involvement of the patient in the management of their own central venous access. During our training project, a more detailed analysis of the stakeholder as well as a swot analysis on the feasibility of the project were used to determine ad interim and final targets of the study. A summary of operative planning is included to explain in greater detail the study design, timing and costs of the various phases. Risk management and corrective measures adopted during the project are also mentioned and monitoring of the phases is described in relation to the fulfilling of intermediate goals. The prompt correction of mistakes allows for safer realisation of outcomes. CONCLUSION From our experience with this work project, we can conclude that a more accurate management of tCVCs can significantly reduce the morbidity and mortality of patients. The project offers a positive cost-benefit balance through a decrease in costs of hospitalisation for tCVC-related infections and other life.threatening conditions related to the use of tCVCs an important goal for any spending review.

Abstract
Angioplasty is the usual method for the treatment of stenosis of arteriovenous fistulas for hemodialysis, along with fibrinolysis and thrombus aspiration. We evaluated the efficacy and safety of interventional radiology procedures in the treatment of stenosis or occlusion of arteriovenous fistulas. One hundred thirteen patients suffering from malfunction of arteriovenous fistulas underwent interventional radiological procedures (140 treatments). In all patients color-Doppler was performed beforehand. Stenosis at the site of the fistula was found in all patients and was treated with percutaneous transluminal angioplasty (PTA); stenosis at the anastomosis site was found in 63 cases and was treated by angioplasty with a microcatheter. In 40 patients suffering from recent thrombotic occlusion, locoregional thrombolysis and PTA were necessary. Technical and clinical success was achieved in 107 patients (94.6%); in 1 of 6 unsuccessful treatments the procedure had to be interrupted due to the rupture of a vein. Follow-up exams demonstrated primary patency in 92.5%, 71.9% and 49.5% of patients at 6 months, 1 year and 2 years, respectively. In 19 patients (17.7%) hemodynamically significant restenosis was observed, which was treated with multiple PTAs (27 treatments, only 1 of which with a negative outcome), resulting in a 94.2% success rate; only 1 patient had to undergo a fourth PTA. The overall patency rate was 95%, 87.2%, 62.3% at 6 months, 1 year and 2 years, respectively. In our experience immediate success and excellent patency rates were observed, which persisted in the medium and long term. PTA, with thrombolysis and thromboaspiration, is the treatment of choice in cases of malfunctioning arteriovenous fistulas. PTA should always be attempted before making a new surgical access in order to preserve the vascular tree.

Abstract
In order to estimate the outcome of arteriovenous fistula (AVF) for hemodialysis, we reviewed our experience in the construction of AVFs using the venae comitantes in patients without an adequate superficial venous vascular territory. The study included 34 patients affected by end-stage renal disease in whom an AVF was created using the deep venous system. In 26 of them we performed an anastomosis between the brachial artery and its vena comitans. Immediate success, defined by the presence of a thrill at the end of the anastomosis, was obtained in 84%, while primary failure of the AVF (immediate postoperative failure) occurred in 3 patients (12%). Early failure, defined as failure within 6 weeks of AVF placement, occurred in 4% of patients. Of the 22 patients with a functioning AVF, 8 (36%) subsequently requested a second operation to bring the fistula to the surface. Some of these involved the placement of synthetic grafts for better accessibility. The primary patency of the AVFs was equal to 64%, while the patency after a second intervention was 91%. Among the 26 AVFs created with venae comitantes, total patency at 50 weeks was 62%. Our experience with the placement of prosthetic grafts draining into the venae comitantes has not provided encouraging results. We believe that for adequate exploitation of venae comitantes it is important to use native veins that have to meet specific anatomical and functional requirements. The creation of an AVF with a native vein, taking advantage of the deep venous system, is feasible under the right circumstances.

Abstract
Aims of the study was validate the venous stenting technique as the treatment of choice in patients affected by stenosis or occlusion of the central venous area. To evaluate the long-term patency of placed stents in our series and to detect factors predisposing to restenosis. Twenty-three hemodialyzed patients were treated by PTA or placement of a metallic self-expandable stent in the central venous area because of occlusion or severe stenosis caused by repeated central venous access puncture for Port-A-Cath or pacemaker placement. All patients were examined every 3 months after treatment by clinical examination and color-Doppler ultrasound. Stents were placed with success in all cases but one, where it was impossible to get past the occlusion. Restenosis was observed in 12 cases at 4 to 12 months (average 8 months). Intrastent restenoses were treated with success by PTA alone and stent placement in 4 cases. A new restenosis was observed in 4 retreated patients in whom the stent was short or angled. In the other patients restenosis was attributable to disregard of anticoagulant therapy. In conclusions, the availability of new devices and dedicated stents is still necessary. There is a limited relationship between patency and wrong stent placement. Patients undergoing stenting should be controlled by clinical examination and color-Doppler ultrasound in hospitals where skilled interventional radiologists are available.

Abstract
Several renal diseases are associated with the dysproteinemias, and their pathogenesis is related to paraprotein deposits in the kidney: light chains can affect the kidney by a direct toxic effect on tubular cells, or by intratubular or tissue precipitation. Multiple myeloma (MM) is the most prevalent dysproteinemia, and the spectrum of associated renal diseases includes myeloma kidney (cast nephropathy), amyloidosis and monoclonal immunoglobulin deposition disease (MIDD). Renal failure is seen in approximately 50% of patients with MM at diagnosis, most frequently attributed to myeloma kidney. Renal function can recover in more than half the patients by prompt rehydration with intravenous fluids, to achieve a urine flow of >3 l/day, and by treating the hypercalcemia. Plasma exchange in combination with corticosteroids is suggested in patients with rapidly progressive renal failure. When renal failure is associated with MIDD or amyloidosis, renal function recovery is reduced to 10%, and patient survival is related to the entity of extrarenal tissue distribution of paraprotein deposits. Dialysis should be offered to patients with end-stage renal disease. High dose chemotherapy and autologous stem cells transplantion (SCT) is recommended in patients who do not have severe co-morbidities.

Abstract
INTRODUCTION Upper gastrointestinal (UGI) disorders are frequent in uremic patients and esophagogastroduodenoscopy (OGD) is an important investigation for their management. SUBJECTS AND METHODS From January 1, 1997 to December 31, 1998, 57 endoscopies were performed in 96 hemodialysis patients (aged 65+/-12 years, 68 M, 28 F, dialysis duration 51+/-58 months) chronically treated in our unit in that period. The reasons for prescribing OGD were: anemia, after exclusion of poor response to EPO, in 26 patients (mean decrease in hemoglobin (Hb) levels 2.6+/-1.3 g/dl: the reference Hb level was the mean value measured before Hb decrease), dyspepsia in 11 and in preparation for renal transplantation in 20 patients. Twelve patients were diabetics, 24 smokers, 41 alcohol drinkers, 13 had hepatitis B or C, 6 were non-steroidal anti-inflammatory drugs (NSAIDs) abusers for bone pain and 21 were taking H2 receptor antagonists or proton-pump inhibitors chronically. Multiple biopsies of gastric mucosa were performed in 38 patients. RESULTS Endoscopy revealed normal mucosa in 17.5% of cases, whilst chronic gastritis was diagnosed in 30%. Chronic gastritis was also the commonest microscopic abnormality diagnosed in 71.5% of biopsies. Anemic and non-anemic patients were matched and the 2 groups did not show significant differences in endoscopic findings and histological appearance. Thirteen patients had Helicobacter pylori (HP) infection demonstrated by biopsy specimen examination and were treated by metronidazole, clarithromycin and omeprazole. A logistic regression analysis was carried out in all subjects, considering the decrement in Hb as a dependent variable and demographic and clinical characteristics as independent variables. The analysis demonstrates that age (odds ratio 1.05; p < 0.05), NSAIDs abuse (odds ratio 15.6; p < 0.05) and HP infection (odds ratio 16.7; p < 0.01) were independently related to Hb decrease. CONCLUSIONS In our experience, non-EPO-related anemia and dyspepsia are frequent features in hemodialysis patients. OGD is frequently requested (30% of patients/year) and 83% of patients investigated had abnormal UGI mucosa. Underlying mucosal inflammation might promote UGI bleeding but is not likely to be the cause, making it a necessary superimposed factor such as NSAIDs or HP infection.

Abstract
AIMS There are few data on the long-term outcome of bone health in renal transplant recipients. We wanted to evaluate the prevalence of osteoporosis and related clinical fractures in long-term survivals to kidney transplantation. METHODS We carried out a cross-sectional study of 80 males and 44 females, aged 45 +/- 1 years, who had undergone kidney transplantation (KTx) 55.6 +/- 4.6 months earlier. Patients were treated according to standard immunosuppressive protocols. RESULTS High parathyroid hormone levels were observed in 55 out of the 124 patients (44.6%) and the prevalence of secondary hyperparathyroidism (SHPT) remained similar even when subjects were grouped according to the time elapsed since transplant. The Z scores for bone alkaline phosphatase, osteocalcin, urinary N telopeptide and galactosyl-hydroxylysine were increased as compared to normal controls, both in males and females (p < 0.05). Bone formation markers normalized, while bone resorption markers remained elevated in these patients even ten years after transplant. Vertebral and femoral osteoporosis were present in 37% and 56% of the patients, respectively, and no tendency toward a recovery in bone mass was seen even in those patients who had survived the longest time since KTx. Clinical fracture rate was 0.006 and 0.031 patient years, before and after KTx, respectively. The number of fractures was lower in patients taking lower mean daily doses of corticosteroids (p < 0.025). PTH levels positively correlated with bone alkaline phosphatase, osteocalcin and N telopeptide. CONCLUSION In conclusion, bone density is decreased and bone turnover increased even many years after KTx, with persistent SHPT and corticosteroid use being the main pathogenetic factors.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most common sustained arrhythmia diagnosed in non-uremic patients and its prevalence increases in older subjects, however, information concerning AF in dialysis patients is scarce. Therefore, we carried out a prospective cross-sectional study from September 1996 to December 1996 in order to evaluate the prevalence and some of the clinical characteristics associated to AF in hemodialysis (HD) patients. SUBJECTS AND METHODS 316 HD patients (age 63 +/- 12 years, dialysis duration 69 +/- 71 months) treated in three different hospital-based units were studied. Standard 12-lead electrocardiograms (ECGs) carried out in the interdialytic day during the study period were reviewed. Data concerning age, history of ischemic heart disease (IHD), cerebrovascular disease (CVD), peripheral vascular disease (PVD), presence of diabetes, smoking history and antihypertensive therapy were collected. Systolic and diastolic blood pressure, fasting cholesterol and triglycerides, albumin and hemoglobin were also derived from the clinical records. Performance status was assessed by Karnofsky index (Ki). RESULTS 74 patients (23.4%) had persistent AF, i.e. presence of AF in all (at least two) ECGs performed in the study time. Patients with AF were older (age 69 +/- 10 vs 62 +/- 12 years, p < 0.001), had lower Ki (54 +/- 20 vs 68 +/- 17, p < 0.01), cholesterol (182 +/- 46 vs 198 +/- 52 mg/dl, p < 0.01) and albumin (3.9 +/- 0.5 vs 4.1 +/- 0.5 g/dl, p < 0.001) compared to those with no AF. Prevalence of IHD (44.5% vs 19%, p < 0.05) and PVD (23% vs 11%, p < 0.05) was higher among AF patients. Logistic regression analysis showed that IHD (p < 0.001) and Ki (p < 0.01) were independently associated to AF. CONCLUSION We conclude that AF is a frequent arrhythmia in HD patients treated in hospital-based dialysis units, especially in those with low performance status. It appears to be associated to the atherosclerotic damage of coronary arterial tree. Prospective studies are necessary to assess whether it could contribute to cardiovascular morbidity and mortality in end-stage renal disease.

Abstract
BACKGROUND Mycophenolate mofetil (MMF) has been successfully introduced into clinical practice with evident benefits for renal transplant recipients. SUBJECTS AND METHODS To evaluate some clinical results of MMF introduction, two groups of subjects underwent cadaveric renal transplants over the last 3 years and were retrospectively investigated. The first group (AZA group) contained 40 subjects (26 males and 14 females) on triple-drug therapy with steroids, cyclosporine and azathioprine (AZA). The second group (MMF group) contained 25 patients ( 19 males and 6 females) on the same regime with steroids and cyclosporine but MMF was administered as a third drug instead of AZA. The AZA group received renal transplant after a mean dialytic time of 32 +/- 19 months and the AZA group's dialytic time was 39.9 +/- 17 months. Clinical data, collected after a minimum 12 months observational period included a crude mortality rate and survival analysis recognized by Kaplan-Meyer curve, creatinine, creatinine clearance, rejection episodes and major clinical events such as infections and acute tubular necrosis. RESULTS One subject died in each group. For kidney graft survival, Kaplan Meyer survival analysis showed a mean survival time of 1170.04 days in the AZA group vs 845 in the MMF group without statistical significance. Graft survival demonstrated 5:40 (12.5%) graft losses in the AZA group vs no kidney transplant loss in the MMF group (the only deceased patient had a well functioning kidney). The curve of graft cumulative proportion survival analysis demonstrated a more improved survival in the MMF group, but this difference did not reach a statistical significance (p = 0.07). Acute rejection episodes in the AZA group were 37.5% vs. 20% in the MMF group. In both groups, CMV infection was successfully treated with specific antiviral agents. CONCLUSIONS MMF represents an important step towards induction and maintenance of immunosuppression. Our experience in a relatively small cohort investigated in a single center, demonstrates encouraging results regarding graft survival in comparison to those detected in conventional triple drug therapy. Surprisingly, in spite of stronger immunosuppressive treatment, the prevalence of CMV infections was not statistically different in the MMF versus the AZA group.

Abstract
BACKGROUND Decreases in bone mass and increased susceptibility to fractures are well-recognized complications in organ transplants. SUBJECTS AND METHODS We performed a cross-sectional study on 60 patients (40 males, 20 females, mean age 43.2 +/- 1.06, SE range 22 - 70) who underwent kidney transplantation (KTX) 55.6 +/- 4.5 months before. Blood and 24-hour urine samples were analyzed for the main parameters of mineral metabolism, and also for osteocalcin (BGP), bone alkaline phosphatase (b-ALP, urine N-telopeptid (u-NTx) and urine galactosyl-hydroxylysine (u-Ghyl). DEXA scan of the lumbar spine (LS) and proximal femur (PF) and ultrasound determination of the heel (stiffness) was also performed. RESULTS T-score values for bone density (BD) were 2.14 +/- 0.11 SD's for LS, -2.56 +/- 0.09 for PF and 2.49 +/- 0.15 for stiffness. There were 29 peripheral fractures in 16 patients. The rate of fractures before KTX were 0.0011 per patient/year and 0.0005 after transplantation (p < 0.02). When expressed as number of SD's with respect to normal controls, BGP (1.48 +/- 0.23), b-ALP (0.95 +/- 0.19), u-NTx excretion correlated negatively with BD at the femoral neck (p < 0.02) and trochanter (p < 0.03). Cumulative steroids intake were negatively correlated with b-ALP positively (p < 0.05). Current CsA was positively correlated with b-ALP (p < 0.001). Both cumulative steroid (p < 0.02) and CSA (p < 0.01) intakes were negatively correlated with BD at Wards triangle. CONCLUSIONS Our data demonstrate an important bone depletion at each stage KTX. PTH plays a major role in the observed increase in bone turnover, exacerbating the negative effects on the bone on immunosuppressive treatment. Glucocorticosteroid therapy is an important risk factor for osteoporosis in this setting also.

Abstract
AIM Chronic hepatitis B is still a matter of concern among renal transplantation patients and patients waiting for a renal transplant since it influences negatively morbidity and mortality. Morbidity and mortality are associated with HBV replication. Lamivudine is a new antiviral agent whose use has been advocated to treat HBV-infected liver transplanted patients. SUBJECT AND METHODS Here we present our experience with an HBV-positive kidney-liver transplanted patient treated with lamivudine after transplantation. RESULTS After lamivudine was started HBV-DNA became negative (chemiluminescence, Digene Hybrid Capture System, USA 1997) and ALT levels returned to normal. After eighteen months and after steroid pulses treatment for acute rejection, HBV-DNA became positive again, probably due to virus mutation. Lamivudine treatment was not withdrawn since it has been suggested that the mutant form might be less pathogenic than the wild one. To this extent, more than 10 months after, our patient is still in a good clinical general condition and still takes lamivudine 75 mg/day. No lamivudine-related side effects were recorded. CONCLUSIONS Our case confirms that lamivudine is a safe and useful tool in treating renal transplant recipients with chronic hepatitis B.

Abstract
The progressively growing number of patients with end-stage renal failure (ESRF) associated with diabetes mellitus and requiring renal replacement therapy (RRT) stimulated both nephrologists and diabetologists to investigate the mechanisms linking hyperglycaemia to diabetic renal failure and to set up measures to prevent the onset and slow the progression of diabetic nephropathy. Over the last few decades, a large number of studies have investigated both the incidence of diabetic nephropathy and the relationship between metabolic control and the development of diabetic nephropathy. Chronologically, the first type of diabetes and diabetic nephropathy to be studied was type I, and it is only in recent years that metabolic control has been proven to be a contributor to the development of nephropathy in such patients. Recently, the DCCT demonstrated that metabolic control in the prealbuminuric phase was effective in reducing the incidence of microalbuminuria, even if it was unable to reduce the incidence of overt proteinuria in patients with type I diabetes and established proteinuria. On the other hand, in type II diabetes, the number of studies demonstrating a favourable effect of metabolic control on onset and progression of diabetic nephropathy is only slightly greater than those that failed to show a favourable effect. This feature may suggest that in type II patients, genetic and ethnic differences, nutritional aspects, lifestyle and other confounding factors may play a relevant role in the course of the disease. However, the trials performed and the retrospective analyses generally agree that glycated haemoglobin two standard deviations greater than the mean is related to a worsening in progression of diabetic nephropathy and to an enhanced risk of other complications. In general, a glycated haemoglobin < or =8% seems advisable. Moreover, in both type I and type II, greater emphasis should be placed on the major risk factors such as hypertension, smoking habits and hyperlipidaemia.

Abstract
BACKGROUND Diabetic nephropathy or diabetes-related nephropathies represents one of the most relevant causes of renal failure in recent years. This complex pathological picture becomes particularly severe as time elapses and after starting renal replacement therapy (RRT). METHODS In an attempt to investigate the evolution of the major clinical features, a retrospective study was carried out on a cohort of 76 diabetic patients on RRT. Sixty-five have been treated by haemodialysis (HD) and 11 by peritoneal dialysis (CAPD), for at least 1 year. In these patients change in modality of treatment, metabolic control, cardiovascular, and ophthalmological complications, peripheral neuropathy, state of vascular access, and intradialytic complications were surveyed at initiation and after 1 year of treatment. A modified Karnofski's score was utilized, to evaluate the degree of rehabilitation. The comparison of prevalence was evaluated, using Student's t-test for paired samples. RESULTS After 1 year, 11 patients on CAPD remained on the same type of treatment. Out of 65 patients on standard bicarbonate HD, 11 were moved to acetate free biofiltration, two to paired filtration dialysis and one to haemofiltration. A worsening in arrhythmias was recorded with an increased prevalence from 25.0 to 35.0% (n.s.), and one more patient (15 vs 16 and 19 vs 20 respectively) experienced ischaemic cardiomyopathy and cerebrovascular insufficiency. Hypertension showed a significant improvement (72 vs 42, P<0.01). Nausea and vomiting, hypotensive episodes, and muscular cramps were more frequently observed. A worsening in patient's welfare was also recorded but without statistical significance. CONCLUSIONS This clinical evaluation even if retrospective and lasting 1 year, may suggest that RRT does not per se represent a cause of the development and progression of the major complications related to diabetic disease.

Abstract
Management of tense ascites in cirrhotic patients on chronic hemodialysis is still a matter of speculation. A considerable problem with these patients is the frequent occurrence of hypotension during ultrafiltration. We describe a patient in whom ascitic fluid was reinfused on the arterial line and ultrafiltrated during standard treatment by using a single dialysis monitor, standard dialysis (SD) lines, and a standard hollow-fiber dialyzer. After 30 to 60 minutes of dialysis, with the patient lying on his left side, a gauge #16 IV catheter was introduced into the left lower abdomen and connected to the reinfusion line. The ascitic fluid was pumped from the abdomen to the arterious inlet of the coil at 500 to 2,000 mL/hr and ultrafiltered. In an individual patient, 13 sessions of ascites reinfusion-ultrafiltration dialysis (ARD) were performed over 3 months and compared with 18 SD sessions performed during the same period. In all procedures, the same SD equipment was used. During ARD, the average weight loss was 2.9 (SD 1.0) kg compared with a weight loss of 0.3 (0.04) kg during SD (P < 0.01). Baseline mean blood pressure was similar in both procedures; after starting dialysis, mean arterial pressure (MAP) dropped by an average of 15 mm Hg at 30 and 60 minutes. Subsequently, during ARD, MAP increased progressively by an average of 20 mm Hg at 180 minutes, whereas MAP did not change significantly during SD. Comparison between procedures by nonparametric one-way analysis of variance showed that body weight became significantly different at 120, 150, and 180 minutes (P < 0.01) and MAP at 150 and 180 minutes (P < 0.02 and P < 0.01, respectively). No major complications occurred. During ARD, on average urea reduction rate was 67%. ARD may represent an effective and safe combination between hemodialysis and the palliative treatment of tense ascites in cirrhotic uremic patients.

Abstract
We report two cases of Kaposi's sarcoma in recipients of solid organ transplants, presenting (Case 1) 12 months after liver transplantation and (Case 2) 7 months after kidney transplantation. Both patients share the following features: natives from the Mediterranean area (Southern Italy), multiple immunosuppressive regimen, infection with hepatitis B and cytomegalovirus. During the 3 yr of follow-up after the diagnosis, their immunosuppressive regimen was reduced and they were treated with alpha interferon with remission of the clinical findings. The management of Kaposi's sarcoma in organ transplant recipients remains a controversial issue because of the risks of organ rejection associated with the reduction of immunosuppression and with the use of interferon.

Abstract
Compared to the still increasing number of kidney, liver and heart transplants performed worldwide, pancreas transplantation remains a rare occurrence. At our center a pancreas transplant program was began in late 1979. Since then a total of 113 pancreas transplants were performed in 106 patients, 100 of them also received a kidney from the same donor. The first group consisted of 5 patients with immediate duct occlusion (IDO). In the second group (n = 8) the pancreatic juice of the segmental graft was diverted into a Roux-Y loop of jejunum. Because of two fatal technique-associated complications, delayed duct occlusion was introduced and applied in 15 patients. Because of a prolonged hospitalization period due to local complications, the surgical technique was changed again. From 1987, 72 segmental pancreatic transplants with bladder drainage were performed and finally one whole organ with a duodenal segment was transplanted. Immunosuppression consisted of cyclosporine A, azathioprine and prednisolone from 1984 on. Rejection episodes were treated with a high-dose methylprednisolone on 3 consecutive days and steroid-resistant rejections with ATG. The overall patient survival at 6 years was 80%, renal allograft survival 72% and pancreas graft survival 63% for the entire group. In the delayed duct occlusion group, 1-year patient and kidney graft survival of 93% each and 79% for the pancreas was calculated. One-year survival in the most recent and largest group with bladder drainage was 89% for patients, 86% for the kidney and 75% for the pancreas. Excellent metabolic control was achieved in the majority of patients with mean C-peptide levels and HbA1C levels at 6 months of 1.46 pmol/ml and 5.6%, respectively. Successful pancreas transplants with normalization of carbohydrate metabolism seem to have a beneficial effect on secondary complications of diabetes, contributing to the high degree of rehabilitation of these patients.

Abstract
Thromboembolic complications constitute an important risk in renal transplant patients, in whom a hypercoagulable state is associated with immunosuppressive treatment, and the presence of hypercoagulability and hypofibrinolysis specifically with cyclosporine. Hypercorticism secondary to steroid treatment has been associated with a thrombophilic state and the presence of a reduced fibrinolytic potential in particular. The aims of this study were to first evaluate the fibrinolytic potential by the venous occlusion (VO) test in 19 renal transplant (RT) patients, and then compare these findings with those obtained in similar groups of normal subjects and patients with Cushing's disease. The following tests were carried out before and after the VO test: euglobulin lysis time and t-PA and PAI-1 activities and antigen. Compared with normal controls, RT and Cushing's patients both showed a similar significant increase in PAI-1 activity and concentration. The VO test revealed a similar impairment in fibrinolytic potential in both the RT and Cushing groups. High and pathological PAI-1 levels before and after the VO test were consistent with a defective fibrinolytic potential due to the inhibitory effect of PAI-1 on plasminogen activation. A hypofibrinolytic state was found in 68.4% of RT patients. Our results suggest that an imbalance in the fibrinolytic system is a typical feature of RT patients one year after transplantation. Steroids appear to be the immunosuppressive drug mainly involved in determining thromboembolic risk after renal transplantation.

Abstract
The initial activity in the field of organ transplantation always brings some organizational and medical difficulties. We describe the first year experience in the field of kidney transplantation at the Transplantation Unit of Padua University. Sixteen kidney transplants from cadaver donors have been performed. A double drug therapy (cyclosporine and steroids) as immunosuppression was used in 9 patients and a triple drug protocol (cyclosporine, steroids, azathioprine) was used in 7. Two patients also received monoclonal antibodies because of steroid resistant rejection. The technical problems we observed include one case of ureteral duplication corrected with uretero-ureteral anastomosis and one substenosis of an ureteral cystoanastomosis corrected with endoscopic dilatation. Among the complications related to immunosuppressive therapy we had one case of severe cyclosporine nephrotoxicity. Two patients died after few months with a functional graft because of pulmonary embolism and because of severe hepatitis complicated by pancreatitis. At an average of six months follow-up all the remaining patients have a good functioning graft.

Abstract
The incidence of acute renal failure (ARF) in severely burned patients ranges from 1.3 per cent to 38 per cent and this complication has always been associated with a high mortality rate, of between 73 and 100 per cent. At present the exact mechanisms responsible for the onset of this complication are not well known. In order to elucidate some of these mechanisms, 20 patients with severe burns were studied for 1 year in an attempt to assess the prevailing glomerular or tubular localization of renal damage; the organic or functional pattern of renal damage and the reliability and possible prognostic significance of some renal function indices. These included the fractional excretion of sodium (FeNa), the alpha-glucosidases, the leucine aminopeptidases (LAP) and the serum and urine beta 2-microglobulin. The incidence of ARF in the patients studied was 26 per cent and in all cases it was of polyuric type. We believe that renal damage very often remains undetected when the traditional testing methods are used and that only in some patients does it become severe enough to result in ARF. In contrast, some of the tests considered in our study are extremely useful and reveal an impairment of renal function long before it becomes clinically apparent.

Abstract
The present study compares the effects of bicarbonate hemodialysis (Bic. HD) and biofiltration (BF), a new hemodiafiltration technique, on plasma volume (PV) changes and extravascular fluid mobilization (Vfm). Ten uremic patients underwent one experimental session of Bic. HD and, one week later, one of BF, both on the second dialysis of the week. Net ultrafiltration rate was limited to 700 ml/min. At the start of each session, whole blood volume (WBV), PV and red cell volume (RCV) were determined using 5 mu Ci of radioiodinated serum albumin (RISA). PV and Vfm were calculated at hourly intervals using a serial hematocrit method. On Bic. HD, PV increased at 60 min. then decreased at 120 and 180 min., with efficient Vfm only during the first hour. On BF, PV increased throughout treatment, with greater Vfm. It would appear that PV is better preserved in BF, on account of more efficient Vfm.

Abstract
1 A woman developed severe mercury intoxication from ingestion of about 2.5 g of mercuric chloride. 2 Antidotal treatment with a dithiol (BAL i.m.) and a monothiol (tiopronin i.v.) was started promptly. 3 Dialysis treatment thereafter markedly increased the elimination of mercury, thus hastening recovery. 4 It is suggested that chelating agents associated with dialysis are an effective treatment for mercury poisoning.

Abstract
Consideration of the precarious mental balance of chronic uraemic patients receiving periodic haemodialysis, which often affects arterial pressure, led to a group of such patients being subjected to additional treatment in the form of Autogenous Training (A.T.). Comparison of some parameters such as arterial pressure and ECG's evaluated before and after A.T. shows, in several cases, a noticeable clinical improvement. It also has a definite tranquillising effect on the general anxiety state, which makes for better and longer-lasting adaptation to periodic dialysis. In the light of these results, Autogenous Training is proposed as a complementary treatment system for obviating certain non-physiological aspects of dialysis.

Abstract
Reference is made to a personal series of vascular accesses for haemodialysis on 273 patients aged 6 months to 70 yr. During the course of 12 years, 533 operations were performed: 109 cannulations of the saphena, 152 by-pass, 251 arteriovenous fistulae (including 22 on patients under 10 yr of age), and 21 "difficult accesses". An assessment of the advantages and disadvantages of the techniques employed showed that the Cimino-Brescia fistula, combined, if necessary, with transient cannulation, is the soundest access owing to its longer life, lower incidence of complications, and better utilisation of the vascular material available.
