Potential Myocardial Iron Content Evaluation by Magnetic Resonance Imaging in Thalassemia Major Patients Treated with Deferoxamine or Deferiprone Dur…
2003
The purpose of this study was to evaluate if the variations of heart magnetic resonance imaging in beta-thalassemia major patients treated with Deferoxamine B mesylate (DF) or Deferiprone (L1) chelation therapy is a useful tool of the indirect myocardial iron content determination. For this reason, a prospective study was carried out. Seventy-two consecutive patients with beta-thalassemia major (35 treated with DF and 37 with L1) were studied. The main outcome results were laboratory parameters including determination of the liver iron concentration (LIC) and magnetic resonance imaging (MRI) of the heart and liver. The heart to muscle signal intensity ratios (HSIRs) were significantly incre…
Hepatic extraction of isosorbide dinitrate in cardiac patients
1983
Hepatic extraction of organic nitrates, including that of isosorbide dinitrate (ISDN), has been thought to be nearly complete in man but has never been directly measured. We examined the time course of plasma ISDN and metabolite concentrations in arterial and hepatic venous blood in four cardiac patients receiving an intravenous ISDN infusion. Apparent hepatic extraction of ISDN was high (90%) at the beginning of infusion but fell to about 44% 1 hr after termination of infusion. The decrease in ISDN concentration gradient across the liver correlates with an increase in plasma isosorbide-5-mononitrate concentration, but a cause-and-effect relationship resulting from metabolite inhibition can…
Increased plasma concentration of fibrin monomer in acute myocardial infarction with early reperfusion.
1996
OBJECTIVE To assess whether plasma fibrin monomer (FM) concentration, a marker of thrombin activity, is increased in the first hours after acute coronary occlusion and whether there are differences between patients with and without early reperfusion. DESIGN Thirty-five consecutive patients with acute myocardial infarction (AMI) and early coronary angiography were studied prospectively. METHODS Plasma FM samples taken on admission (< 6 h after onset of chest pain) and 6-14 h after onset of chest pain were analysed using a specific enzyme immunoassay. All of the patients were anticoagulated with heparin intravenously. RESULTS Of the 35 patients, 28 had angiographically documented reperfusion …
Osteonecrosis of the jaws by intravenous bisphosphonates and osteoradionecrosis : a comparative study
2009
Aims: We analyze the possible clinical differences between bone jaw exposed areas in ONJ (osteonecrosis of the jaws) and ORN (osteoradionecrosis). Patients and method: Group 1 was composed with 53 ONJ cases and group 2 with 20 ORN cases. In both groups we analyzed, the major size of the exposed bone areas, the number of exposed areas, the location on the jaws and the presence of others associated and severe complications, such as skin fistulas and jaw fractures. We also investigated the possible local aetiology or trigger factor of the lesions. Results: The major size of the bone exposed areas was 2.29±2.02(mean ± std.dev) in group 1 and 2.7±2.9 (mean ± std.dev) in group 2 (p>0.05). The num…
High-dose furosemide and small-volume hypertonic saline solution infusion for the treatment of leg edema in advanced cancer patients.
2008
Peripheral edema is a common feature in populations with advanced cancer, although it is seldom recognized. Diuretics are commonly employed and may show some benefit, but there are insufficient clinical trial data to draw useful conclusions about their clinical use. The aim of this prospective study was to evaluate the efficacy and tolerability of high-dose furosemide and small-volume hypertonic saline solution infusion in reducing leg edema in patients with advanced cancer treated unsuccessfully with diuretics. A prospective study was performed in a consecutive sample of 24 patients admitted to a pain relief and palliative care unit over a period of 18 months. To be eligible to enter the t…
Back pain after photodynamic therapy with verteporfin.
2005
Purpose To report the incidence of back pain after photodynamic therapy, which suggests methods for prevention that are related to its pathogenesis. Design Retrospective case series. Methods We retrospectively observed 548 patients who had undergone photodynamic therapy with verteporfin. Results Of 548 patients at the first treatment, 14 patients (2.6%) experienced pain during the infusion. Eleven patients were being treated for age-related macular degeneration; their mean age was 81 years, which significantly differed from the mean age of the overall age-related macular degeneration group ( P = .003). The pain was mild in eight patients, moderate in four patients, and severe in two patient…
Gemcitabine, oxaliplatin and weekly high-dose 5-FU as 24-h infusion in chemonaive patients with advanced or metastatic pancreatic adenocarcinoma: a m…
2006
ABSTRACT Background: Combinations of gemcitabine–oxaliplatin, gemcitabine–5-fluorouracil (5-FU) and 5-FU–oxaliplatin have synergistic activity and nonoverlapping adverse effect profiles. This trial assessed efficacy and safety of the triple combination gemcitabine–oxaliplatin and infusional 5-FU in patients with locally advanced (n = 11) or metastatic (n = 32) pancreatic adenocarcinoma. Patients and methods: A total of 43 eligible patients were treated with intravenous infusions of gemcitabine (900 mg/m2 over 30 min), followed by oxaliplatin (65 mg/m2 over 2 h) and 5-FU (1500 mg/m2 over 24 h) on days 1 and 8 of a 21-day cycle. Results: Among all 43 patients, the tumor response rate was 19% …
Ventilator-Associated Lung Injury Superposed to Oleic Acid Infusion or Surfactant Depletion: Histopathological Characteristics of Two Porcine Models …
2009
<i>Background:</i> The pathophysiological concept of acute lung injury (ALI) in combination with ventilator-associated lung injury (VALI) is still unclear. We characterized the histopathological features of intravenous injection of oleic acid (OAI) and lung lavage (LAV) combined with VALI. <i>Methods:</i> Pigs were randomized to the control, LAV or OAI group and ventilated by pressure-controlled ventilation. Measurements included: haemodynamics, spirometry, blood gas analysis, lung wet-to-dry weight ratio (W/D), total protein content in broncho-alveolar lavage fluid (BALF), and lung pathological description and scoring. <i>Results:</i> Five hours after lu…
Antigen carbohydrate 125 and creatinine on admission for prediction of renal function response following loop diuretic administration in acute heart …
2014
The use of loop diuretics in acute heart failure (AHF) is largely empirical and has been associated with renal function impairment by reducing renal perfusion but also renal improvement by decreasing renal venous congestion. Antigen carbohydrate 125 (CA125) has emerged as a proxy for fluid overload. We sought to evaluate whether the early changes in creatinine (ΔCr) induced by intravenous furosemide doses (ivFD) differ among clinical groups defined by overload status (CA125) and creatinine on admission (Cr).We included 526 consecutive patients admitted for AHF. All patients received intravenous furosemide for the first 48 hours. CA125 and Cr were dichotomized at 35 U/ml and 1.4 mg/dl, respe…
Effects of high-dose furosemide and small-volume hypertonic saline solution infusion in comparison with a high dose of furosemide as bolus in refract…
2003
Background Diuretics have been accepted as first-line treatment in refractory congestive heart failure (CHF), but a lack of response to them is a frequent event. A randomized, single-blind study was performed to evaluate the effects of the combination of high-dose furosemide and small-volume hypertonic saline solution (HSS) infusion in the treatment of refractory New York Heart Association (NYHA) class IV CHF and a normosodic diet during follow-up. Materials and Methods One hundred seven patients (39 women and 68 men, age range 65-90 years) with refractory CHF (NYHA class IV) of different etiologies, who were unresponsive to high oral doses of furosemide, angiotensin-converting enzyme inhib…
