[The development of a bedside cart for the management of acute respiratory failure with non-invasive ventilation in Internal Medicine wards]. / Lo sviluppo di un carrello "bedside" per la gestione dell'insufficienza respiratoria acuta con ventilazione non invasiva nei reparti di Medicina Interna.

In order to improve the organization of a General Medical ward without a real critical care area and to optimize treatment of patients with acute respiratory failure, we developed a cart for non-invasive ventilation to be used at the patient bedside. In the rear panel, we set two i.v. drip poles used for i.v. therapy and to hold two Venturi-like flow generators for continuous positive airway pressure. On the top, two ventilators are present, a smaller one (domiciliary) and a bigger one (intensive care unit ventilator). In the front panel, there are 4 drawers called "blood - drugs", "oxygenation", "CPAP", "ventilation", in which all the devices for ventilation, oxygenation, aerosol and medical therapy are easily and quickly available. The management of acute respiratory failure is simpler, easier and safer with this cart: each necessary device is immediately available, and this avoids wasting time. This bedside non-invasive ventilation cart, as far as the cardiac emergency cart, can be useful in general medical wards lacking a critical care area in order to improve interventions in patients with acute respiratory failure.

[Benign multicystic peritoneal mesothelioma. A case report]. / Mesotelioma multicistico peritoneale benigno.

Benign multicystic peritoneal mesothelioma is a rare malignancy with unknown etiology, first described in 1980, which have been reported to date about 150 cases in the literature. Although the term "benign", used mainly to distinguish it from the classic malignant mesothelioma, a more aggressive cancer, is considered "borderline" in terms of aggression: it tends to local recurrence but cases of lymph node metastases or in other locations at a distance are not described. The symptoms are often vague and nonspecific (abdominal pain, enlarged abdomen and ascites). The common diagnostic imaging techniques (CT, MRI) may appear similar to ovarian or peritoneal cancer by more aggressive mesenchymal neoplasms. Histological examination, accurately with the aid of immunohistochemical techniques, is therefore essential for diagnosis. Treatment is surgical and consists of peritonectomy. After surgery, the prognosis is generally good. In 50% of cases may have local recurrences; so rigorous follow-up is indicated.

[Continuous positive airway pressure in acute pulmonary edema. application in a general medical ward]. / Sistemi CPAP (Continuous Positive Airway Pressure) nell'edema polmonare acuto cardiogenico: loro impiego in Reparto di Medicina Interna.

BACKGROUND: The application of a Continuous Positive pressure to Patient's airway (CPAP) represents one of the most important respiratory treatments during Acute Respiratory Failure (ARF) due to Acute Cardiogenic Pulmonary Edema (ACPE). Thanks to its hemodynamic and ventilatory effects, CPAP improves clinical and gasanalytic parameters and lead to a decrease of mortality and need of intubation in these patients. CPAP can be applied with different devices: ventilators, Venturi-like flow generators and Boussignac's device. AIM: To verify and to compare effectiveness and tolerability of two different CPAP's devices (Venturi-like flow generator and Buossignac's device) in ARF due to ACPE. The study was performed in a General Medical Ward. MATERIALS AND METHODS: 20 patients with ARF due to ACPE were randomized in two group: the first group (10 patients) received CPAP with a Venturi-like flow generator, the second group (10 patients) with Boussignac's device. At the end of CPAP treatment each patient gave a score to tolerability. RESULTS: In each group we noted a significant (p<0.05) improvement in clinical and gasanalytic parameters since the first hour of treatment; these improvements were confirmed in following determinations and were not significantly different in the two group of patients. The Boussignac group showed a better tolerability. CONCLUSIONS: The two CPAP's devices resulted similar in term of effectiveness. Boussignac's device has shown a better tolerability: this characteristic, together with the simple use, should stimulate the diffusion of this device where a flow generator or a ventilator are not present (outside Intensive Care Units, for example in General Medical Wards).

[Echocardiographic evaluation of anti-tumor necrosis factor-alpha therapy with infliximab in patients without cardiac pathologies]. / Effetti del trattamento anti-Tumor Necrosis Factor-alpha con infliximab in pazienti non cardiopatici: valutazione ecocardiografica.

In the course of heart failure, plasmatic levels of Tumor Necrosis Factor-alpha (TNF-alpha) are high and are related to prognosis and mortality. Infliximab, a recombinant chimeric antibody anti-TNF-alpha, was used in heart failure with disappointing results, similar to those obtained with other biological drugs.The aim of this study was the echocardiographic evaluation of infliximab infusion in nine patients without cardiac pathologies. The findings demonstrate a reduction of sistolic function and a modification of diastolic function after infliximab infusion in patients without cardiopathy. This study confirms the protective role played by TNFalpha on the myocardium, as suggested by previous experimental studies.

[Budd-Chiari syndrome with fatal outcome in a patient with polycythemia vera and antiphospholipid antibody syndrome]. / Sindrome di Budd-Chiari a decorso fatale in paziente con policitemia vera e sindrome da anticorpi antifosfolipidi.

We report the case of a 41-year-old woman, affected by Vaquez syndrome, admitted to our hospital for a severe pain in the right hypochondrium, suddenly followed by hepatomegaly and ascites. The clinical and laboratory data were suggestive of hepatic insufficiency and abdominal ultrasonography, integrated by color Doppler and computed tomography, revealed an interrupted hepatic venous outflow. In addition a spontaneous prolonged partial thromboplastin time was present and the patient was found to be positive for lupus anticoagulant. A transient clinical improvement, with a partial reperfusion of suprahepatic veins, was achieved with medical treatment by using anticoagulants, diuretics and paracentesis. However, the patient showed a subsequence of suprahepatic venous thrombosis, although two transjugular intrahepatic portosystemic shunts with stent placement and local thrombolysis were performed. The polycythemia vera is a disease mainly associated with Budd-Chiari syndrome but, in our patient, the thrombotic event occurred in spite of normal values of hematocrit and platelet count. Certainly in this case the lupus anticoagulant positivity represents an additional thrombogenic factor. Nowadays the antiphospholipid antibody syndrome is a recognized and not unusual cause of Budd-Chiari syndrome but, to our knowledge, this is the first case characterized by the presence of polycythemia vera and antiphospholipid antibody syndrome to be reported.

[Prevalence of degenerative aortic valve stenosis in the elderly: results of a large community-based epidemiological study]. / Prevalenza della stenosi aortica degenerativa negli anziani: risultati di uno studio epidemiologico di comunità

BACKGROUND: There is a paucity of epidemiological data on the prevalence of degenerative aortic stenosis (AS) after the recent demographic changes and in the present therapeutic era. We sought to assess the prevalence of AS in an elderly population of an Italian urban area and to derive an epidemiological estimate of AS prevalence on a larger scale. METHODS: Elderly people (aged 75-95 years) of a 26 000 inhabitants town were clinically screened by general practitioners and classified into four groups: (1) no signs of AS; (2) known AS; (3) suspected AS (on the basis of the presence of a systolic murmur); (4) prior aortic valve replacement (AVR). Group 2 and 3 patients underwent physical examination and transthoracic echocardiography to confirm or rule out the diagnosis of AS, and to assess main comorbidities. RESULTS: Among the eligible patients, 2203 (93.7%) had no sign of AS; 49 (2.1%) had known AS; in 74 (3.1%) there was a systolic murmur suggesting AS, and 26 (1.1%) had previous AVR because of AS. Ten patients refused further screening, therefore 113 patients underwent transthoracic echocardiography. Among them, degenerative aortic disease without stenosis was observed in 22, and 63 had confirmed AS (severe in 21). Important comorbidities were frequently diagnosed in these patients. Including patients with previous AVR, AS was confirmed in 89/2350 patients (3.8%). On a regional scale, based on the demographics of this area, we estimated a prevalence of severe AS of 2248 cases per million inhabitants. CONCLUSIONS: The prevalence of AS in a population aged 75-95 years was 3.8%, and it was not previously diagnosed in a sizable proportion. More attention for early diagnosis of AS in the elderly is warranted.

Cardiac involvement in Crohn's disease: echocardiographic study.

BACKGROUND: Crohn's Disease (CD) commonly presents extra-intestinal manifestations, but cardiac involvement is considered rare. The aim of the present study was to assess cardiac involvement in CD and its possible correlation with activity, duration, localization and therapy. PATIENTS AND METHODS: A group of 68 patients with CD and a control group of 60 healthy subjects were subjected to a transthoracic echocardiogram with Doppler study. RESULTS: The study found overall morphologic alterations in 47/68 CD patients (69.11%) versus 12/60 controls (20.0%; P < 0.01); mitral valve prolapse in 20/68 CD patients (29.4%) versus 4/60 controls (6.6%; P < 0.01); and pericardial effusion in 13/68 CD patients (19.1%)versus 1/60 controls (1.6%; P < 0.01). The following findings were frequent, but without statistical significance: mitral insufficiency, 9/68 CD (13.2%) versus 3/60 controls (5.0%); tricuspidalic insufficiency, 8/68 CD (11.7%) versus 3/60 controls (5%); aortic insufficiency, 3/68 CD (4.4%) versus none in the control group; and decreased left ventricle ejection fraction, 5/68 CD (7.3%) versus none in the control group. Pericardial effusion was found to be related to CD activity (r = 0.375; P = 0.002) as well as decreased ejection fraction (r = 0.358; P = 0.003). No correlation with age, sex, duration, therapy or localization of disease was found. CONCLUSIONS: These findings suggest that CD frequently determines cardiac involvement, although it is usually subclinical. The alteration of cytokine network, especially the elevated levels of tumor necrosis factor-alpha, could be implicated in the cardiac alterations because it was observed, as for raised oxidative stress, in other heart diseases.
