Efficacy and Tolerability of Biweekly Bevacizumab, Irinotecan, Folinic Acid and Fluorouracil Intravenous Bolus (BIFF Regimen) in Patients With Metast…
2011
Abstract Background We have extensively assessed a biweekly regimen of irinotecan plus folinic acid and fluorouracil bolus (IRIFAFU) in metastatic colorectal cancer (MCRC). Here, we report on the safety and activity of BIFF (bevacizumab plus IRIFAFU) regimen in 94 mCRC patients. Patients and Methods Bevacizumab 5 mg/kg (1 hour), and irinotecan 180 mg/m 2 (1hour) were given intravenously on day 1, 6S-folinic acid 250 mg/m 2 (2 hours), and fluorouracil 850 mg/m 2 (bolus) were given intravenously on day 2 every 2 weeks for a median of 9 cycles per patient (range, 1-12), and maintenance bevacizumab alone was delivered in 16 cases. Results Grade ≥ 3 hematologic toxicities were neutropenia (50%) …
Salmonella-reactive Synovial Fluid T-cell Clones in a Patient with Post-infectious Salmonella Arthritis
1990
From a patient with reactive arthritis following Salmonella typhimurium enteritis, synovial fluid T-lymphocytes were cloned and expanded in vitro. Seven out of 74 clones showed a marked proliferative response to antigens of heat-killed Salmonella typhimurium with autologous T-cell-depleted peripheral blood mononuclear cells as antigen-presenting cells. The Salmonella-reactive clones were of the CD4+ phenotype, antigen-induced proliferation could be inhibited by a monoclonal antibody to HLA class II. One clone recognized both Salmonella and Campylobacter jejuni antigens in the proliferation assay. The multiclonality of Salmonella-reactive synovial fluid T-cells indicates that the microorgani…
Voxel-based morphometry depicts central compensation after vestibular neuritis.
2010
Objective Patients who have had vestibular neuritis (VN) show a remarkable clinical improvement especially in gait and posture >6 months after disease onset. Methods Voxel-based morphometry was used to detect the VN-induced changes in gray and white matter by means of structural magnetic resonance imaging. Twenty-two patients were compared an average 2.5 years after onset of VN to a healthy sex-and age-matched control group. Results Our analysis revealed that all patients had signal intensity increases for gray matter in the medial vestibular nuclei and the right gracile nucleus and for white matter in the area of the pontine commissural vestibular fibers. A relative atrophy was observed in…
The hippocampus is required for short-term topographical memory in humans.
2007
The hippocampus plays a crucial role within the neural systems for long-term memory, but little if any role in the short-term retention of some types of stimuli. Nonetheless, the hippocampus may be specialized for allocentric topographical processing, which impacts on short-term memory or even perception. To investigate this we developed performance-matched tests of perception (match-to-sample) and short-term memory (2 s delayed-match-to-sample) for the topography and for the nonspatial aspects of visual scenes. Four patients with focal hippocampal damage and one with more extensive damage, including right parahippocampal gyrus, were tested. All five patients showed impaired topographical m…
Increased Vaccination Coverage among Adolescents and Young Adults in the District of Palermo as a Result of a Public Health Strategy to Counteract an…
2018
During the summer of 2016 four cases of invasive meningococcal disease in rapid succession among young adults in the district of Palermo, Italy, resulting in one death, were widely reported by local and national mass media. The resultant ‘epidemic panic’ among the general population overloaded the vaccination units of the Palermo district over the following months. Strategies implemented by the Sicilian and local public health authorities to counteract ‘meningitis fear’ included the following: (a) extension of active and free-of-charge anti-meningococcal tetravalent vaccination from age class 12–18 to 12–30 years old; (b) implementation of vaccination units during normal clinic hours in roo…
Circulating VEGF reduction, response and outcome in advanced colorectal cancer patients treated with cetuximab plus irinotecan
2007
Objective: We designed this trial to investigate if modifications in levels of circulating vascular endothelial growth factor (VEGF) may be related to clinical response and outcome in advanced colorectal cancer patients during treatment with a weekly combination of cetuximab plus irinotecan. Methods: A total of 45 heavily pretreated metastatic colorectal cancer patients were prospectively evaluated for circulating levels of VEGF during the treatment with cetuximab plus weekly irinotecan. VEGF circulating levels were assessed at the following time points: just before and at 1, 21, 50 and 92 days after the start of cetuximab plus irinotecan treatment. Results: Basal VEGF median levels were s…
Angiogenesis modifications related with cetuximab plus irinotecan as anticancer treatment in advanced colorectal cancer patients
2006
INTRODUCTION Angiogenesis has been correlated with increased invasion and metastases in a variety of human neoplasms. Inadequate inhibition of the growth of tumor microvessels by anticancer agents may result in treatment failure, rated clinically as progressive or stable disease. We designed this trial to investigate the modification of the vascular endothelial growth factor (VEGF) and interferon-gamma (IFN-gamma) in advanced colorectal cancer patients during treatment with a weekly combination of cetuximab plus irinotecan. MATERIALS AND METHODS Forty-five metastatic colorectal cancer patients were prospectively evaluated for circulating levels of VEGF and IFN-gamma during the treatment wit…
Recognition memory for single items and for associations in amnesic patients
2004
Recognition memory performance reflects two distinct processes or types of memory referred to as recollection and familiarity. According to theoretical claims about the two types of memory, single item and associative recognition tasks can be used as an experimental method to distinguish recollection and familiarity processes. Associative recognition decisions can be used as an index of recollection while memory for single items is mostly based on familiarity judgement. We employed this procedure to examine a possible dissociation in the memory performance of amnesic patients between spared single item and impaired associative recognition. Twelve amnesic patients, six with damage confined t…
Phytosterol plasma concentrations and coronary heart disease in the prospective Spanish EPIC cohort
2010
Phytosterol intake with natural foods, a measure of healthy dietary choices, increases plasma levels, but increased plasma phytosterols are believed to be a coronary heart disease (CHD) risk factor. To address this paradox, we evaluated baseline risk factors, phytosterol intake, and plasma noncholesterol sterol levels in participants of a case control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) Spanish cohort who developed CHD (n = 299) and matched controls (n = 584) who remained free of CHD after a 10 year follow-up. Sitosterol-to-cholesterol ratios increased across tertiles of phytosterol intake (P = 0.026). HDL-cholesterol level increased, …
Amplitude envelope correlation detects coupling among incoherent brain signals.
2000
Event-related potentials (ERPs) to changes in the visual environment were recorded in rabbits. In the oddball condition, infrequently presented (deviant) stimuli occurred in a series of frequently presented (standard) stimuli. In the deviant-alone condition, standards were omitted. ERPs to oddball-deviants differed from those to standards in all recording sites (cerebellar cortex, visual cortex, dentate gyrus). No corresponding differences were found between ERPs to deviants in the oddball condition and those in the deviant-alone condition. However, because ERPs to deviants in the deviant-alone condition and those to standards did not differ either, ERPs to stimulus changes in the oddball c…
