RESUMO
Pseudoaneurysm occurs when the artery wall is damaged and the blood is contained by the surrounding tissues with the eventual formation of a fibrous sac communicating with the artery. We report a case of a 74-year-old man with inferior epigastric artery (IEA) pseudoaneurysm secondary to an 8-mm port placement during a robot-assisted laparoscopic radical cystectomy with ureteroileocutaneostomy. The pseudoaneurysm was initially diagnosed by contrast-enhanced ultrasound (CEUS); subsequently, a computed tomography (CT) scan and an angiography test were performed. The pseudoaneurysm was then treated successfully with embolization of the inferior epigastric artery. Awareness of this rare complication is of clinical importance to avoid excessive morbidity of affected individuals.

Our aim was to identify subclinical right ventricular (RV) alterations in systemic lupus erythematosus (SLE) by combining standard and three-dimensional echocardiography (3DE). Fifty SLE patients without concomitant cardiac disease and 50 healthy controls, matched for age and gender, were enrolled. Disease damage was evaluated by inflammatory markers and SLE damage index. All patients underwent an echo-Doppler examination with 3DE assessment of RV function, RV septal and lateral longitudinal strain. The two groups had comparable body mass index and blood pressure. RV transversal middle diameter and pulmonary arterial pressure were significantly higher in SLE compared to controls. By 3DE, RV end-systolic volume ( p = 0.037) was greater, whereas stroke volume ( p = 0.023), ejection fraction ( p < 0.0001) and septal and lateral longitudinal strain (both p < 0.0001) were lower in SLE. SLE damage index ≥ 1 was negatively associated with tricuspid annular plane systolic excursion (TAPSE) ( p < 0.002), tricuspid E/A ratio ( p = 0.003), RV ejection fraction ( p < 0.05), lateral longitudinal strain ( p < 0.0001) and septal longitudinal strain ( p = 0.04). By separate multivariate models, after adjusting for age, C reactive protein and proBNP, SLE damage index was independently associated with TAPSE ( p = 0.009) and RV lateral longitudinal strain ( p = 0.007). In conclusion, a subclinical RV systolic dysfunction is detectable in SLE by 3DE, RV lateral wall strain being a key parameter. RV dysfunction is associated with cumulative disease damage.

Chronic venous insufficiency and chronic venous ulcers represent an important medical problem, because of the high incidence and prevalence in the general population, and need to be considered as a lifelong degenerative condition, with socioeconomic consequences. Ulceration is a severe complication of the post-thrombotic syndrome, often precipitated by minor trauma. The rate of post-thrombotic syndrome varies between 20% and 100% of patients with deep vein thrombosis, mostly occurring within two years of an initial thrombotic event. This syndrome is difficult to treat, causes significant disability and reduces the quality of life. To date, there are no effective therapies of chronic venous ulcers and no definite strategies for identifying patients at risk for the development of ulceration. The role of adequate compression with elastic stockings is well recognized. Several systemic drugs have been tested for a possible effect on chronic venous ulcer healing, but none has been widely accepted as standard therapy in this setting. It has been suggested that extended oral anticoagulation should be investigated as a possible preventative measure. Waiting for the results in this field, an adequate management of anticoagulation in terms of anticoagulant intensity and duration should be recommended for the prevention of recurrent deep vein thrombosis, post-thrombotic syndrome and chronic venous ulcers.

Giant cell arteritis is a systemic vasculitis characterized by granulomatous inflammation of the aorta and its main vessels. Cardiovascular risk, both for arterial and venous thromboembolism, is increased in these patients, but the role of thromboprophylaxis is still debated. It should be suspected in elderly patients suffering from sudden onset severe headaches, jaw claudication, and visual disease. Early diagnosis is necessary because prognosis depends on the timeliness of treatment: this kind of arteritis can be complicated by vision loss and cerebrovascular strokes. Corticosteroids remain the cornerstone of the pharmacological treatment of GCA. Aspirin seems to be effective in cardiovascular prevention, while the use of anticoagulant therapy is controversial. Association with other rheumatological disease, particularly with polymyalgia rheumatica is well known, while possible association with antiphospholipid syndrome is not established. Large future trials may provide information about the optimal therapy. Other approaches with new drugs, such as TNF-alpha blockades, Il-6 and IL-1 blockade agents, need to be tested in larger trials.
RESUMO
The aim of this double blind randomized clinical trial was to compare the short-term and long-term outcomes of stapled haemorrhoidopexy (SH group) performed using a circular stapler with that of the Milligan-Morgan haemorrhoidectomy (MMH group). A total of 79 consecutive patients with grade III haemorrhoids were randomized into two groups treated with SH (n. 39) and MMH (n. 40). The outcomes of the procedures were evaluated postoperatively and over a follow-up period of minimum 2 years. Patients undergoing the SH procedure showed greater short term advantages than MMH group with reduced pain, shorter length of hospital stay, earlier return to work and high patient satisfaction. Long-term follow-up has indicated more favourable results in MMH group in terms of resumption of symptoms with absence of residual prolapse and risk of recurrence of prolapse. At two years follow-up recurrent prolapse was confirmed in six patients of SH group (13%) whereas in none of the MMH group. At six months follow-up there weren't significant difference in the mean satisfaction score for the two groups. At two years the mean satisfaction score was higher in the MMH group vs SH group. Seven patients in the SH group needed a reoperation whereas none in MMH group. From January 2009, in our Surgery Unit the patients are always informed about a higher recurrence rate of SH and we perform this technique only when the patient choices to accept this risk to take advantage of the short-term benefits of this procedure.

The public health burden of air pollution has been increasingly recognized over the last decades. Following the first assessed adverse effects on respiratory diseases and lung cancer, a large body of epidemiologic and clinical studies definitely documented an even stronger association of air pollution exposure with cardiovascular mortality and morbidity, particularly related to atherothrombotic (coronary and cerebrovascular) disease. Particulate matter (PM), mainly that with lower aerodynamic diameter (fine and ultrafine PM), is responsible for the most severe effects, due to its capacity to transport toxic substances deep into the lower airways. These effects have been shown to occur not only after short-term exposure to elevated concentrations of pollutants, but even after long-term relatively low levels of exposure. Vulnerable subjects (elderly persons and those with preexisting cardiopulmonary diseases) show the highest impact. Fewer and conflicting data also suggest an association with venous thromboembolism. Although not completely elucidated, a series of mechanisms have been hypothesized and tested in experimental settings. These phenomena, including vasomotor and cardiac autonomic dysfunction, hemostatic unbalance, oxidative stress and inflammatory response, have been shown to change over time and differently contribute to the short-term and long-term adverse effects of pollution exposure. Beyond environmental health policies, crucial for improving air quality and reducing the impact of such an elusive threat to public health, the recognition and assessment of the individual risk, together with specific advice, should be routinely implemented in the strategies of primary and secondary cardiovascular prevention.

Despite the high incidence of abdominal traumas, traumatic abdominal wall hernias (TAWHs) remain rare probably because of elasticity of the abdominal wall. The TAWH is due to blunt abdominal trauma with disruption of the abdominal wall muscles and fascia with intact overlying skin. TAWH can be classified into high energy injures (generally motor vehicle accidents) and low energy injures (impact on a small blunt object). Common example of the latter type is a fall onto a bicycle handlebar. The mechanism of the trauma includes sudden increase of intra-abdominal pressure and extensive shear forces applied to the abdominal wall. The diagnosis of TAWH is difficult in the Emergency Room because during the primary diagnostic process most attention is directed toward the detection of internal injures and TAWH can be missed. In this article we report a case of TAWH caused by a work accident (an heavy steel tube fallen onto the abdominal wall of the patient from a height of five meters) with delayed diagnosis.

We sequenced the SERPINC1 gene in 26 patients (11 males) with antithrombin (AT) deficiency (22 type I, 4 type II), belonging to 18 unrelated families from Southern Italy. Heterozygous mutations were identified in 15/18 (83.3%) families. Of them, eight were novel mutations, each being identified in one family. Seven clearly cause impaired protein synthesis (four frameshift, one non-stop, one splicing and one 21bp deletion). One, present in a single patient, is a missense mutation thought to be causative because: a) it is absent in 100 chromosomes from controls; b) it involves a highly conserved amino acid, whose change is predicted to impair AT activity; c) no other mutation is present in the propositus. Severe mutations (i.e. nonsense, frameshift, deletions) were invariably identified in type I patients. In type II patients, 3/4 were missense mutations; the fourth leads to a 19 nucleotides shift in the stop codon. In addition to the type of mutation, the co-existence of other predisposing factors in most patients helps explain the severity of the present type I cases (age at first event, recurrence during prophylaxis). In the five families in which there was more than one member affected, the same genotype and a concordant clinical expression of the disease were found. We conclude that the molecular bases of AT deficiency in Southern Italy are different as compared to other geographic areas, and that molecular analysis and the study of the effect of the mutation may help predict the clinical expression of the disease.

Diabetes mellitus (DM) is associated with macrovascular and microvascular complications. Platelets have a "key role" in atherogenesis and its thrombotic complications in subjects with DM. Moreover, the concomitant presence of multiple "classical" cardiovascular risk factors in diabetic subjects contributes to enhanced atherothrombotic risk. Antiplatelet agents are effective in primary and secondary prevention of arterial thrombosis (cardiovascular events, ischaemic stroke, and peripheral arterial occlusive disease). The role of chronic administration of antiplatelet drugs in primary prevention of arterial vascular events is known to be less clear than in secondary prevention, and, also in diabetic patients, the decision to give primary prophylaxis should be taken on an individual-patient basis, after a careful evaluation of the balance between the expected benefits and the risk of major bleedings. Although, currently, treatment has proven useful in reducing vascular events, diabetic patients continue to have a higher risk of adverse cardiovascular events compared with those in nondiabetic patients. This paper reviews the role of currently available antiplatelet drugs in primary and secondary prevention of vascular events in diabetic patients and the limitations of these drugs, and it discusses the role of novel and more potent antiplatelets and of new agents currently under clinical development.

BACKGROUND: Although patients with idiopathic VTE are at higher than normal risk of asymptomatic atherosclerosis and of cardiovascular events, the impact of cardiovascular risk factors on VTE is poorly understood. OBJECTIVE: To assess the prevalence of the metabolic syndrome and of its components in patients with early-onset idiopathic VTE. METHODS: As many as 323 patients referred to our Thrombosis Ward for a recent (<6-months) early-onset idiopathic venous thromboembolism (VTE), were compared with 868 gender- and age-matched subjects, in whom a history of venous thrombosis had been excluded, referred during the same period time to our Ward. All had undergone a clinical assessment for smoking habits and for the presence of the components of the metabolic syndrome. RESULTS: The metabolic syndrome was detected in 76/323 cases (23.5%) and in 81/868 controls (9.3%) (p<0.001; OR:2.990; 95%C.I.:2.119-4.217). Smoking was more common in patients with idiopathic VTE than in controls. In addition to the metabolic syndrome as a whole, its major individual determinants (arterial hypertension, impaired fasting glucose plasma levels, abdominal obesity, hypertriglyceridemia, low HDL-cholesterol) significantly correlated with idiopathic VTE (p always <0.05). The prevalence of thrombotic events was lower in females than in males (p=0.000; OR:2.217), the latter being most often hypertensives, smokers, hypertriglyceridemics, carriers of a metabolic syndrome and of impaired fasting glucose than females. In a multivariate analysis, arterial hypertension, impaired fasting glucose, abdominal obesity, and hypercholesterolemia independently predicted idiopathic venous events. CONCLUSIONS: Both metabolic syndrome as a whole and its major components individually considered, independently predict early-onset idiopathic VTE.

A relationship between thyroid function and obesity seems likely, mainly influenced by the insulin resistance. Whether variations in TSH and/or thyroid hormones, within a normal range, can influence body weight or if obesity per se can alter thyroid function has not been clarified so far. Further studies are necessary to assess the link between thyroid function and body weight, that must consider not only changes of thyroid hormones, but also body fat distribution, obesity duration and the state of low grade inflammation. It is recognized that thyroid function is linked not only to body mass index, but also to body composition and, particularly, to the amount and percentage of fat mass.

Antiphospholipid antibodies are a heterogeneous group of auto-antibodies against phospholipids-binding proteins. The antiphospholipid syndrome is an autoimmune disorder characterized by the clinical association of antiphospholipid antibodies with a condition of hypercoagulability that can affect any blood vessel. Involvement of larger vessels, such as arteries or veins, manifests in the form of thrombosis or thromboembolism, whereas involvement of small vessels manifests as thrombotic micro-angiopathy. The antiphospholipid syndrome is also characterized by the presence of recurrent fetal loss. Patients who are persistently positive for antiphospholipid tests, and who have an arterial thrombosis or venous thrombosis history, are at increased risk of recurrence. Oral anticoagulant therapy is the mainstay of treatment for the thrombotic manifestations of the syndrome. Therapy with anticoagulant drugs should be long-term. On the other hand, although the thromboembolic potential of antiphospholipid antibodies has been well documented, there is still no general consensus on the prophylactic treatment of antiphospholipid antibodies carriers who have never developed vascular/obstetric manifestations. The effect of primary prophylaxis in antiphospholipid antibodies positive individuals is not well known and no evidence-based recommendations exist for thrombosis prevention in these individuals. However, the presence of risk factors for thrombosis increases the risk of first event of antiphospholipid antibodies positive patients. In conclusion, there is still much to learn on primary prophylaxis of asymptomatic antiphospholipid antibodies carriers. Hopefully, evidence-based guidelines will be available in the future.

Injected factor VIII (FVIII), the current treatment for haemophilia A, leads to major improvements in the quality of life and life expectancy of individuals with this disorder. However, because injected FVIII has a short half-life in vivo, this strategy has major limitations for highly demanding regimens (e.g. prophylaxis, immune tolerance induction, surgery). Newer formulations of longer-acting FVIII are presently under investigation. The use of low molecular weight polyethylene glycol (PEG)-containing liposomes as carriers for recombinant FVIII (rFVIII) results in the prolongation of haemostatic efficacy. Data from preclinical experiments in mice, early clinical evaluations, and pharmacokinetics and pharmacodynamics results indicate that an rFVIII pegylated liposomal formulation may provide potential clinical benefit to patients with severe haemophilia A by prolonging the protection from bleeding. In light of this potential clinical benefit, a multicentre, randomized, active-controlled, non-inferiority phase II trial with two parallel treatment arms and equal randomization after stratification for the presence or absence of target joints in patients and for ages >/=18 years vs. <18 years is currently being conducted. The study will test the hypothesis that rFVIII-Lip once-weekly prophylaxis is not inferior to rFVIII-water for injection thrice-weekly prophylaxis. A total of 250 patients will be enrolled with severe haemophilia A (<1% FVIII) on on-demand or secondary prophylaxis treatment and with documented bleeds or injections during the 6 months before study entry. Sixty-four centres in 14 different countries are involved in the study; recruitment is underway. In Italy, six centres have already included 15 patients (no screening failure). Eight of these patients have completed the run-in phase and have begun the home treatment. No unexpected serious adverse events have been reported thus far. Data emerging from this phase II study will help collect relevant data to overcome current limitations in haemophilia management by employing treatment with longer-acting rFVIII.

BACKGROUND: Radiofrequency thermal ablation is the first therapeutic option in percutaneous treatment of hepatocellular carcinoma but data on its long-term efficacy and safety are not conclusive. AIM: This study reports a prospective survey on radiofrequency thermal ablation in north-east Italy. METHODS: Data were collected on 401 patients with hepatocellular carcinoma (males 301, mean age: 68 years) treated by radiofrequency thermal ablation in 13 centres. Indication to treatment was: single nodule not eligible for surgery in 77% of patients, 2-3 nodes in 18% and multiple lesions in 5%. Mean size was 3 cm (1-8 cm). Treatment response was assessed at 1 month by spiral computerized tomography and then with ultrasound examination and new spiral computerized tomography. RESULTS: Complete response was obtained in 67% of patients and in 27% response was 75-99%. Complete response raised to 77% in lesions smaller than 3 cm. The morbidity rate was 34%; the mortality was 0.5%, seeding was observed in four patients. Ten patients presented an unexpected rapid disease progression. CONCLUSION: The above data show that by radiofrequency thermal ablation, complete response can be achieved only in about two-third of the cases, clearly less than expected, and that, beyond seeding, unexpected progression can be observed.
