Heterogeneous delayed enhancement of hepatic parenchyma after intravenous infusion of sonographic contrast agent: a new hypothesis

2007

Purpose. The aim of this paper was to report a heterogeneous latephase hepatic enhancement pattern observed after administration of a sonographic contrast agent and to present an aetiological hypothesis for the phenomenon. Materials and methods. A total of 1,729 (1,012 women and 717 men; age range 28–82; mean age 51) patients underwent contrastenhanced sonography of the liver. The examination was performed with a low mechanical index (MI <0.09) after injection of sulphur-hexafluoride-filled microbubbles, using different fonographic equipment and different contrast-specific algorithms. Results. Heterogeneous delayed liver enhancement was observed in six patients in the late phase (180 s), wi…

Relationship between preoperative anxiety and postoperative satisfaction in dental implant surgery with intravenous conscious sedation

2008

Purpose: To study if patient preoperative anxiety is related to age and gender and to compare preoperative anxiety with postoperative patient and surgeon satisfaction in dental implant surgery under intravenous conscious sedation. Materials and Methods: Dental implants were placed in 102 patients under local anesthesia and intravenous conscious sedation. The procedures were performed with or without dental extractions, and with or without bone regeneration. Anxiety was evaluated using Corah?s Dental Anxiety Scale and levels of surgeon and patient satisfaction were evaluated on an adapted scale. Results: Low preoperative anxiety was observed in 27.8% of patients, moderate in 50%, and high in…

Phase 1B Study of the Pharmacokinetics and Safety of Posaconazole Intravenous Solution in Patients at Risk for Invasive Fungal Disease

2014

ABSTRACT This was a phase 1B, dose-ranging, multicenter, pharmacokinetics, and safety study of cyclodextrin-based posaconazole intravenous (i.v.) solution administered through a central line to subjects at high risk for invasive fungal disease (part 1 of a 2-part study [phase 1B/3]). Initially, the safety and tolerability of single-dose posaconazole i.v. 200 mg ( n = 10) were compared with those of a placebo ( n = 11). Subsequently, 2 doses were evaluated, posaconazole i.v. 200 mg once daily (q.d.) ( n = 21) and 300 mg q.d. ( n = 24). The subjects received twice-daily (b.i.d.) posaconazole i.v. on day 1, followed by 13 days of posaconazole i.v. q.d., then 14 days of posaconazole oral suspen…

The Effects of Prostaglandin E-1 in Patients with Intermittent Claudication

2006

Aim of the study is to evaluate the effects of Prostaglandin E-1 (PGE-1) in patients with peripheral arterial disease (PAD) at the 2nd b stage Fontaines classification. The study, controlled, single blinded, enrolled 123 patients with intermittent claudication that were randomised in two groups; the first group received a treatment with PGE-1 while the second one received a pentoxifylline-buflomedil association by venous infusion. We evaluated: Pain Free Walking Distance (PFWD), Maximum Walking Distance (MWD), Rest Flow (RF), Peak Flow (PF), Basal (BVR) and Minimal Vascular Resistance (MVR) with a strain gauge plethysmograph, Resting Flow (RF), Peak Flow (PF), time to reach the Peak Flow (t…

Oral high-dose sucrosomial iron vs intravenous iron in sideropenic anemia patients intolerant/refractory to iron sulfate: a multicentric randomized s…

2020

AbstractIron deficiency anemia is among the most frequent causes of disability. Intravenous iron is the quickest way to correct iron deficiency, bypassing the bottleneck of iron intestinal absorption, the only true mechanism of iron balance regulation in human body. Intravenous iron administration is suggested in patients who are refractory/intolerant to oral iron sulfate. However, the intravenous way of iron administration requires several precautions; as the in-hospital administration requires a resuscitation service, as imposed in Europe by the European Medicine Agency, it is very expensive and negatively affects patient’s perceived quality of life. A new oral iron formulation, Sucrosomi…

Iloprost treatment in patients with Raynaud's phenomenon secondary to systemic sclerosis and the quality of life: a new therapeutic protocol

2006

Objectives: to evaluate the clinical efficacy and the effects on the quality of life of Iloprost, a prostacyclin analogue, used, according to a new protocol, in patients with Raynaud’s phenomenon secondary to Systemic Sclerosis. Methods: in this randomized study we treated 30 patients with Iloprost given by intravenous infusion, at progressively increasing doses (starting from 0.5 ng/Kg/min up 2 ng/Kg/min) over a period of 6 hours a day for ten days in two consecutive weeks, with repeated cycles at regular intervals of three months for 18 months. The results were compared with those obtained in 30 other patients, who had received the same drug but with different posologic schemes. Results: …

Pharmacokinetics of atenolol in relation to renal function

1981

The plasma levels and urinary excretion of carteolol and its main metabolites 8-hydroxycarteolol and carteolol glucuronide were investigated in 6 healthy subjects and 9 patients with varying degrees of renal impairment following a single oral dose of 30 mg carteolol hydrochloride. In healthy subjects the half-life of carteolol was 7.1 h. 63% of the administered dose was recovered unchanged in urine, and in all 84% was excreted by the kidneys. The renal clearance of carteolol was 255 ml/min. In chronic renal failure (CRF) the terminal half-life was increased to a maximum of 41 h. Both the elimination rate constant and renal clearance were closely related to the creatinine clearance. In CRF t…

Effect of intravenous application of esomeprazole 40???mg versus pantoprazole 40???mg on 24-hour intragastric pH in healthy adults

2007

BACKGROUND: It has been demonstrated that therapy with proton pump inhibitors reduces recurrence of bleeding following initial endoscopic treatment of bleeding peptic ulcers. AIM: This study compared the effects of esomeprazole 40 mg and pantoprazole 40 mg on intragastric acid control. Both substances were administered intravenously as 15-min infusion and as bolus injection. METHODS: Healthy men and women volunteers were enrolled in this single-center, open, randomized, three-way crossover study. After administration of esomeprazole 40 mg and pantoprazole 40 mg intravenously as 15-min infusion, and pantoprazole 40 mg intravenously as bolus injection, continuous 24-h intragastric pH monitori…

Hemodynamic and ventilatory changes during implant surgery with intravenous conscious sedation

2010

Purpose: This study was conducted to determine the hemodynamic and ventilatory changes during implant surgery with intravenous conscious sedation, and whether preoperative anxiety, gender or age influence these parameters. Patients and Methods: A prospective study carried out between May 2004 and February 2007, on 102 patients treated with dental implants under local anesthesia and conscious intravenous sedation. Patients completed a questionnaire prior to surgery to evaluate preoperative dental anxiety using Corah's scale. The hemodynamic and ventilatory changes were evaluated by monitoring systolic pressure (SP), diastolic pressure (DP), heart rate (HR) and oxygen saturation (SaO2). These…
