Hepatocellular cancer response to radiofrequency tumor ablation: contrast-enhanced ultrasound
2007
Radiofrequency ablation (RFA) is increasingly being used as percutaneous treatment of choice for patients with early stage hepatocellular carcinoma (HCC). An accurate assessment of the RFA therapeutic response is of crucial importance, considering that a complete tumor ablation significantly increases patient survival, whereas residual unablated tumor calls for additional treatment. Imaging modalities play a pivotal role in accomplishing this task, but ultrasound (US) is not considered a reliable modality for the evaluation of the real extent of necrosis, even when color/power Doppler techniques are used. Recently, newer microbubble-based US contrast agents used in combination with grey-sca…
Incidence of new foci of hepatocellular carcinoma after radiofrequency ablation: role of multidetector CT
2012
Purpose. The authors sought to assess the incidence of new foci of hepatocellular carcinoma (HCC) using multidetector computed tomography (MDCT) in patients treated with radiofrequency ablation (RFA). Materials and methods. Two readers retrospectively reviewed by consensus the follow-up MDCT studies of 125 patients (88 men and 37 women; mean age 68 years) with 141 HCCs (size 1–5.2 cm; mean 2.2 cm) treated with RFA. MDCT follow-up was performed at 1 and 3 months and every 6–12 months thereafter. Reviewers assessed: (1) the presence of new HCC foci in the same liver segment or in a different segment; (2) complete or incomplete tumor ablation; (3) tumour progression. Results. A total of 113 ne…
Response to transarterial chemoembolization as a biological selection criterion for liver transplantation in hepatocellular carcinoma.
2006
Criteria to select patients with hepatocellular carcinoma (HCC) for liver transplantation (LT) are based on tumor size and number of nodules rather than on tumor biology. The present study was undertaken to assess the role of transarterial chemoembolization (TACE) in selecting patients with tumors suitable for LT. Ninety-six consecutive patients with HCC were treated by repeatedly performed TACE, 62 of them exceeding the Milan criteria. Patients meeting the Milan criteria were immediately listed, and patients beyond the listing criteria were listed upon downstaging of the tumor following successful TACE. Fifty patients were finally transplanted. Of these 50 patients, 34 exceeded the Milan c…
When GLP-1 hits the liver: a novel approach for insulin resistance and NASH
2012
nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum ranging from simple steatosis to steatohepatitis (NASH), increasing fibrosis and eventually, cirrhosis ([22][1]). Importantly, NASH accompanied by fibrosis and severe inflammation is the most relevant predictor for disease progression
Preclinical dementia: an Italian multicentre study on amnestic mild cognitive impairment
2006
<i>Background:</i> Different rates and cognitive predictors of conversion to dementia have been reported in subjects with different kinds of mild cognitive impairment (MCI). <i>Methods:</i> A prospective, 24-month follow-up study, involving 269 subjects who strictly fulfilled criteria for the amnestic MCI. <i>Results:</i> Conversion rate to dementia was 21.4% per year. Seventy-nine out of the 83 individuals who developed dementia were affected by probable Alzheimer’s disease (AD). Among others, at the 24-month follow-up 24.1% were still affected by amnestic MCI, 13.3% had changed their neuropsychological profile of impairment and 17.2% were cognitively no…
Relationship between transforming growth factor beta1 and progression of hypertensive renal disease.
2002
In this study the role of circulating transforming growth factor beta1 (TGFbeta1) on progression of renal hypertensive disease has been investigated. Fifty consecutive outpatients with essential hypertension were enrolled and divided into three groups, according to their urinary albumin excretion (UAE). Group A comprised 10 hypertensives with UAEor=20 mg/24 h (normoalbuminuric group); Group B included 21 hypertensives with UAE20300 mg/24 h (microalbuminuric group); Group C encompassed 19 hypertensives with UAEor= 300 mg/24 h (proteinuric group). In all patients UAE by immunonephelometric assay, circulating TGFbeta1 by a solid phase specific sandwich ELISA technique, BUN and creatinine by ro…
Inflammatory bowel disease in patients over the age of 70y. Does the disease duration influence its behavior?
2018
Introduction: The fastest growing segment of our population is that of people above 70 years of age. Elderly patients with IBD exhibit several specific problems. Our objective was to evaluate the clinical course, the side effects of the treatments and the need for surgery of elderly patients, regardless of the age of onset.Materials and Methods: This was a cross-sectional study wherein retrospective data were collected from multiple centers from seven hospitals within the Valencia metropolitan area. Data were collected on patients older than 70y with inflammatory bowel disease.Results: We identified a total of 331 patients older than 70 years of age (5.3% of patients monitored at our center…
Cholesterol levels and risk of hemorrhagic transformation after acute ischemic stroke.
2011
<i>Background:</i> The association between cholesterol levels and hemorrhagic transformation (HT) is still controversial. Studies investigating this issue are influenced by treatments as some are characterized by a higher risk of HT. The aim of our study was to evaluate, in a hospital-based series of patients not treated with thrombolysis, the relationship between cholesterol levels and HT. <i>Methods:</i> We retrospectively collected information about total cholesterol (TC) and low-density lipoprotein cholesterol (LDLC) levels at admission in a consecutive series of 240 patients with anterior ischemic stroke (IS). The TC and LDLC levels were arranged in 3 groups acc…
Prospective evaluation of the macroscopic types and location of early Barrett’s neoplasia in 380 lesions
2007
The macroscopic appearance of early gastric cancers, classified according to the Japanese criteria, has been shown to be an important prognostic factor for local endoscopic therapy. No prospective data about the distribution of macroscopic types and their location in early Barrett's neoplasia are available, however. The present study was conducted to evaluate the clinical applicability of this macroscopic classification and to analyze the relative proportions of the different gross types in early Barrett's neoplasms and the correlation between the macroscopic classification and the stage or grade of differentiation.A total of 344 patients with 380 Barrett's neoplastic lesions who were refer…
Legal and assistance aspects of Alzheimer's disease: analysis of 100 cases.
2003
Caring for patients with disabling cognitive diseases, such as Alzheimer's disease (AD) and other progressive dementias, has a number of legal and social welfare implications. The two main problems to be discussed with patients and caregivers are the need for a legal guardian and requests for government financial support, both of which depend on the patient's progressive loss of autonomy and increasing need for assistance. In order to study the presence of these two support measures, we considered 100 AD patients (56 women and 44 men) divided in four groups on the basis of the stage of the disease: mild (25), moderate (34) and severe (32), or death (9). We investigated the number of caregiv…
