[Cardiologic diagnosis of pulmonary embolism: echocardiography].

Pulmonary embolism (PE) represents the third more frequent cardiovascular disease following the acute coronary artery disease and stroke. The most important predisposing clinical condition for PE is represented by the deep-vein thrombosis. The clinical diagnosis of PE has a very low accuracy; so the clinical suspect has to be necessarily directed towards the performance of diagnostic procedures. Among the most used procedures, the echocardiography has a diagnostic role but also a prognostic one. Moreover, it offers precious informations useful to perform the most suitable treatment. The echocardiography features which suggest the presence of pulmonary embolism are: right ventricle and atrium dilatation, right ventricular hypokinesia, systolic flattening of the interventricular septum, tricuspid regurgitation, pulmonary artery dilatation, disappearance or reduction of the inspiratory collapse of the inferior vena cava and presence of eventual embolic sources. According to the involvement degree of right ventricular function, it is generally possible to identify a different survival. The subgroup of patients with moderate or severe right ventricular dysfunction shows a high in hospital and within 1 year death rate. For this reason the right ventricular dysfunction degree together with the hemodynamic stability, are the most important parameters in the therapeutic choice. If there is no right ventricular dysfunction a treatment with heparin is indicated. In presence of right ventricular dysfunction and hemodynamic instability, the thrombolytic treatment is necessary. If the patient is hemodynamically stable, a transesophageal echocardiography is recommended; in case of central thrombosis the thrombolytic therapy or surgery are needed, while if no embolic material is shown the heparin treatment is advisable.

[Evolution in the pharmacological treatment of venous thrombosis according to evidence-based medicine].

Today therapeutic protocols must be in accordance with Recommendations derived by Randomized Controlled Trials (RCT) Evidences. Deep Venous Thrombosis (DVT), post-thrombotic syndrome and pulmonary embolism (PE) are different forms of the thromboembolic venous disease. The Authors, according with Evidence-Based Medicine, review the most significant RCT about Low-Molecular-Weight Heparin (LMWH). It has been proved that LMWH is more efficacious, easier to administrate and with less significant side effects than Unfractioned Heparin (UH) in DVT treatment. Its higher anti-Xa than anti-IIa activity provides higher anti-thrombotic properties and lower haemorrhagic risk. LMWH does not require anticoagulant monitoring and allows outpatient--ambulatory care. RCT also showed lower PE ratio and lower haemorrhagic risk with LMWH outpatient care than with UH in-hospital care for DVT. RCT showed also a long-term lower DVT relapse and PE incidence with LMWH than with oral anticoagulants. The Authors report their own experience with LMWH and early ambulation for the treatment of DVT versus standard UH therapy. Their retrospective analysis confirms lower incidence of complications: growth of the thrombus, severe haemorrhages, PE.

[Physical treatment of deep venous thrombosis: bed rest or mobilization?].

The need of prolonged bed-rest for the treatment of Deep Venous Thrombosis (DVT), which was considered essential to control the thrombotic phenomenon and to prevent Pulmonary Embolism (PE) until ten years ago, has now been critically reviewed in the light of the great success of the Low Molecular Weight Heparin (LMWH) in medical therapy of DVT. There is a great evidence for bed-rest and immobility to play a pivotal role in the growth and in the progression of a venous thrombosis. The Authors emphasize, both on the international reports and their own experience, that, in most cases, medical treatment of DVT consists of an outpatient--ambulatory care based on immediate mobilization and ambulation, on external compression therapy, on early LMWH administration and late oral anticoagulation. This regimen provides great benefits in order to prevent PE, to improve the quality of life, to reduce the hospital and the anticoagulant monitoring charges.

[Compression therapy in deep venous thrombosis].

External compression, both intermittent by pneumatic pumps and continuous by anelastic or elastic bandages and by graduate compression stockings, play a pivotal role in prophylaxis of Deep Venous Thrombosis (DVT). The use of external compression in DVT therapy and in prophylaxis of pulmonary embolism (PE) and of post-thrombotic syndrome has not been validated as well as in DVT prophylaxis. The pathophysiologic properties of the external compression and the most recent evidences about the early mobilization of the patients with DVT and about Low Molecular Weight Heparin (LMWH) therapy suggest the advantages of the external compression. The authors review the most important clinical investigations about early use of external compression in DVT joined with pharmacological therapy: the results have been the reduction of the growth of the thrombus, the reduction of PE ratio, the prevention of the post-thrombotic syndrome, the indirect improvement of the quality of life. Finally the authors confirm the recommendations about the use of physical therapy with early mobilization and external compression joined with LMWH anticoagulation in DVT.

[Cardiorenal physiopathology and heart failure: current aspects and therapeutic prospects].

The heart and the kidney exert a reciprocal control of their function in order to maintain a steady state of haemodynamics, both in physiological and pathological conditions. The functional relationship between the two organs becomes particularly evident during heart failure. The knowledge of such relationship may play an important role in the management of heart failure. We also report here our experience in the treatment of congestive heart failure with depletive techniques vicarious of kidney function.

[Treatment of refractory heart failure with different dialysis technics].

The efficacy of the dialysis in the heart failure non responsive to the traditional methods is well known. In our study we have evaluated the effects of three different dialytic methods (UFI: ultrafiltration isolate; HF: hemofiltration; CAVH: continuous arteriovenous hemofiltration). These methods are used to cause a good depletion in the patients with intractable heart failure following from ischaemic valvular or primitive cardiomiopathy. We have treated 18 patients (6 for each method) and the patients with organic or functional renal disease were treated with the methods (HF and CAVH) that have depletive and depurative effects. Each of these methods is capable, without important differences, of achieving the following aim: the hydro-sodium depletion, the correction of the haemodynamic alteration and the re-establishment of the response to the traditional medical treatment. Using the hemofiltration and continuous arteriovenous hemofiltration, both soft methods, we have obtained values of dehydratation, absolute and for each session, higher than isolated ultrafiltration. The follow-up has not pointed out differences, of both prognosis and survival among patients treated with the three methods studied, whose effects are always only temporary; only the heart transplantation or the valvular correction, by operating in a very important way on the basal cardiopathy, is the resolutive event.

[Report on long-term hemofiltration in the treatment of end-stage renal failure].

Thirteen uraemic patients in chronic hemofiltration was studied over a 37.3 +/- 25.4 months period. Hemofiltration value in long-term treatment of uraemia was verified by: dialytic adequacy, clinical data, complications, drop-out morbidity and survival. Our experience indicates that hemofiltration and especially high efficiency hemofiltration is an effective and soft therapy for substitutive long-term treatment in high risk patients.

[Chronic idiopathic intestinal pseudo-obstruction associated with volvulus of the transverse colon. The identical mode of clinical presentation and of the intestinal manometric pattern in monozygotic twins].

Two monozygotic female twins with chronic idiopathic intestinal pseudo-obstruction associated with transverse colon volvulus are described. Quite similar clinical events and temporal coincidences characterized the symptoms which has preceded and followed right colectomy undergone by both of them due to intestinal volvulus. The esophageal, gastroduodenal, colonic and anorectal manometric investigation revealed very similar alterations in both girls. Increased amplitude of distal contractions of the esophagus, a depressed fasting antro-duodenal motility, with absence into antrum and oro-aboral non-propagation in the duodenum of the phase III activity of the interdigestive motor complex were the main findings along with a state of pronounced colonic hypomotility and an hypoesthesia of the rectal ampulla to the volumetric stimulus. This report indicates the association between chronic intestinal pseudo-obstruction and transverse colon volvulus in monozygotic female twins, and it points out the rarity both of the specific symptomatic coincidences and the similar clinical events and of the almost absolute identity of the intestinal motor patterns.

The coagulative system in haemodialyzed patients: the relationship between the elderly and hypertrygliceridaemia.

The coagulative system has an important role on haemodialysis and on atherosclerosis genesis; in particular the platelets are key elements of the coagulation and of atherosclerosis phenomena. Alterations of the coagulative system and increase risk of developing atherosclerosis are reported in the aging. We in this paper, report the results obtained studying the influence of the interaction between the elderly and dyslipidemia on the coagulative system in haemodialyzed patients. The obtained data showed that the hypertriglyceridaemia in interaction with the elderly accelerates and increases platelet aggregation after stimulation by ADP, Epinephrine and Collagen. So, it is important to consider hypertriglyceridaemia and age as thrombogenic factors and atherosclerosis accelerating factors in haemodialyzed patients.

Nosography and immunopathogenesis of viral hepatitis.

Five viruses are responsible for the vast majority of cases of viral related hepatitis. They have been named hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), hepatitis E virus (HEV). The more recent literature concerning the viral structure, the epidemiology, the serological identification, the clinical course and the prevention of each type of hepatitis is reviewed. HBV is not directly cytopathic. Hepatitis is a consequence of the destruction of the virus-infected cells. The efficient elimination of the virus relies on the viral antigenic determinants (HBs, pre-S1, pre-S2, HBc, HBe) and on the immune system of the host. The viral persistence may be caused by defect of the host immunity (interferon production, T and B lymphocyte function) or by factors related to the virus such as a genome mutation (lack of HBe formation). Some evidence suggesting an immunopathogenetic mechanism also for HCV, HDV and HAV is reported.

Evidence for Raynaud's syndrome among haemodialyzed patients: influence of flunarizine treatment.

A bloodless study with a Photoplethysmographic test of the limb's blood circulation among haemodialyzed patients with arteriovenous fistula and the influence of Flunarizine treatment was performed. All patients showed a blood reduction flux on the hand with fistulas in front of the controlateral limb. Three patients affected by Raynaud Syndrome were identified. The Flunarizine treatment did not show significative blood flux variations among among those patients with low Photopletysmographic index (P.I.) in the limb with arteriovenous fistula, while a significative increase of P.I. was registered in the limb of the patients affected by Raynaud Syndrome. Concluding, the Photopletysmographic test is useful to follow the limb's blood circulation of haemodialyzed with arterio-venous fistula, being it bloodless, sure and repeteable test to follow the influence of vasoactive therapy.

Long-term therapy with slow-release nifedipine in essential hypertension.

The purpose of this study, designed as an open multicenter trial, was to test the antihypertensive efficacy, patient acceptability, and side effects of long-term treatment with slow-release nifedipine in a large population. The drug was studied in 330 outpatients with essential hypertension, WHO stage 1-2, recruited in 20 hospital centers. After washout period was completed, nifedipine (20 mg bid) was given for 1 month (phase 1). Then, the treatment was extended for 4 months (phase 2) with variable doses (range 20-80 mg daily). No other antihypertensive drugs were administered during phase 1. However diuretics, beta blockers, or captopril were added to nifedipine during phase 2 in 11 patients. Seventy patients did not meet criteria for inclusion at washout. During phase 1 and 2, 66 additional patients were excluded due to side effects, the need of other antihypertensive drugs, or non-compliance. Systolic blood pressure significantly lowered (10% or more) in 84% patients in phase 1 and in 76% in phase 2. No responders were 6.1% and 3.6%, respectively. Diastolic blood pressure was normalized in 60% of patients after 5 months of therapy. Effects on blood pressure were equal in young patients and in the elderly, but a minimal rise in heart rate was recorded in younger patients. At least one side effect occurred in 46.6% patients, mainly headache (15.4%), hot flashes (13.3%), ankle edema (12.8%), or palpitation (6.6%). Sixteen patients (8.2%) were obliged to stop nifedipine treatment due to the severity of the side effects. This trial confirms the efficacy of nifedipine in hypertension, both in young and in aged patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Concealed ventricular hexageminy.

The authors report a case of concealed ventricular hexageminy in which, with a few exceptions, extrasystoles were separated by sinus beats conforming to the formula 6n - 1. Whenever an exception to this formula occurs, the intervening beats are not all of sinus origin, but include also a ventricular extrasystole that is different from those occurring in hexageminal distribution. The pattern is explained by a parasystolic rhythm modulated by sinus impulses, assuming a 3:1 ratio between the parasystolic cycle and the sinus cycle. Such a ratio would have to be associated with a trigeminal or concealed trigeminal distribution. There is, however, a 2:1 ectopic-ventricular block, leading to a change of the ectopic distributional pattern from the expected concealed trigeminy to that of the concealed hesageminy.

[Correlation between the sites of mitral annular calcification and conduction disturbances: echocardiographic evaluation].

A clinical, electrocardiographic and echocardiographic (M-Mode, 2D) study was performed to explain the causal relationship between mitral annular calcification and cardiac conduction disturbances. Forty-seven patients, 28 women and 19 men (mean age 69) with mitral annular calcification were studied. In 18 patients A-V and/or intraventricular conduction disturbances were present. In this study we have found: a greater incidence of posterior than anterior mitral annular calcification; the anterior mitral annular calcification is often associated with aortic valve calcification and ultimately the common association between anterior mitral annular calcification and conduction disturbances.

[Treatment of recent atrial fibrillation with intravenous propafenone].

Intravenous propafenone (1 mg/Kg in 3 min) has been administered to 14 patients with recent atrial fibrillation. The sinus rhythm was restored in 7 patients within 30 min after the injection. The left atrial size, evaluated by M-mode echocardiography, was no different in the group of responders, with respect to the non-responders. No adverse effect has been observed. One single patient manifested a long asystolic pause (3860 ms), at the restoration of sinus rhythm. Propafenone appears to be useful in the treatment of recent atrial fibrillation.
