PANCREATIC CARCINOMA VERSUS CHRONIC FOCAL PANCREATITIS: CONTRAST-ENHANCED POWER DOPPLER ULTRASONOGRAPHY FINDINGS
2005
Background: We assessed the potential usefulness of contrast-enhanced power Doppler ultrasonography (US) for differentiating pancreatic carcinoma from chronic focal pancreatitis. Methods: Twenty-six consecutive patients with ductal carcinoma (n=16) and chronic focal pancreatitis (n=10) underwent power Doppler US examinations before and after intravenous injection of an air-based contrast agent (Levovist, Schering, Berlin, Germany). Final diagnosis was obtained by surgery in all patients. The following parameters before and after intravenous administration of contrast agent were evaluated for each lesion: number, morphology and course of the vessels within the lesion and time to maximum dete…
Ocular pseudomyasthenia: report of a case with a pineal region tumor.
1991
A case presenting with clinical features of ocular myasthenia and a false-positive edrophonium test is reported. Brain CT and MRI scan revealed a pineal region tumor histologically verified as germinoma. We recommend evaluating patients with clinical features of myasthenia gravis (MG) confined to the ocular muscles for intracranial mass lesions.
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…
Is ultraviolet exposure acquired at work the most important risk factor for cutaneous squamous cell carcinoma? Results of the population-based case-c…
2018
Background Squamous cell carcinoma (SCC) is among the most frequent types of cancer constituting a significant public health burden. Prevention strategies focus on limiting UV-exposure during leisure time. However, the relative impact of occupational and non-occupational UV-exposure for SCC occurrence is unclear. Objectives To investigate the association between occupational and non-occupational UV-exposure with SCC in a multicenter population-based case-control study hypothesizing that high occupational UV-exposure increases the risk for SCC. Methods Consecutive patients with incident SCC (n=632) were recruited from a German national dermatology network. Population-based controls (n=996) w…
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…
Neuroticism, extraversion, stressful life events and asthma: a cohort study of middle-aged adults
2009
ABSTRACT Background: Stressful life events can trigger asthma exacerbations, but could also contribute to the development of incident asthma. However, only few studies have investigated the association between stressful life events and adult asthma prospectively. Likewise, stress-related personality traits (e.g. neuroticism and extraversion) may increase asthma risk, but this has been examined in only one prospective study. We therefore aimed to investigate the association between neuroticism, extraversion, stressful life events and incident asthma. Methods: A population-based sample of 5114 middle-aged adults completed questionnaires between 1992 and 1995. Among those alive in 2002/2003, 4…
Are referral centers for non-muscle invasive bladder cancer compliant to EAU guidelines? A report from the vesical antiblastic therapy Italian study
2011
<i>Introduction:</i> Adherence to international guidelines is viewed as a prerequisite for optimal medical care delivery. Previously reported surveys for non-muscle-invasive bladder cancer (NMIBC) employed mailed questionnaires to urologists or patients resulting in conflicting degrees of agreement with existing guidelines. In the current study, contemporary information on the management of NMIBC was generated from a sample of Italian centers. <i>Patients and Methods:</i> Eight Italian referral centers for the treatment of NMIBC were asked to collect information relative to all consecutive patients with a histology-proven NMIBC undergoing a transurethral resection fr…
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…
