Genetic, clinical and radiographic signs in knee osteoarthritis susceptibility
2014
Abstract INTRODUCTION: Osteoarthritis (OA) is considered to be a multifactorial and polygenic disease and diagnosis is mainly clinical and radiological. Correlation between radiographic data and clinical status has been reported. However, very few studies, especially in Caucasian people, describe the association between the Kellgren and Lawrence OA grading scale (KL) and genetic alterations to better understand OA etiopathogenesis and susceptibility. In order to update the knee OA grading, in this study we assessed the associations between KL grade, clinical features such as American Knee Society Score (AKSS), age, and polymorphisms in the principal osteoarthritis susceptibility (OS) genes …
Characterization of circadian COPD symptoms by phenotype: Methodology of the STORICO observational study
2017
Abstract Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. The symptoms of COPD are troublesome, variable, can occur during all parts of the 24-h day and have a substantial impact on patients' health status, quality of life and healthcare resource utilization. Reducing symptoms, improving health status and increasing physical activity are major goals in the management of stable COPD. In order to provide effective, patient-oriented care, patients should be evaluated on the basis of lung function, frequency of symptoms and patient-perceived impact of symptoms on their lives and treatment decisions made on a case-by-case basis. The …
Blood pressure and low-density lipoprotein-cholesterol lowering for prevention of strokes and cognitive decline: a review of available trial evidence.
2014
BACKGROUND AND OBJECTIVES:: It is well established by a large number of randomized controlled trials that lowering blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) by drugs are powerful means to reduce stroke incidence, but the optimal BP and LDL-C levels to be achieved are largely uncertain. Concerning BP targets, two hypotheses are being confronted: first, the lower the BP, the better the treatment outcome, and second, the hypothesis that too low BP values are accompanied by a lower benefit and even higher risk. It is also unknown whether BP lowering and LDL-C lowering have additive beneficial effects for the primary and secondary prevention of stroke, and whether these…
PHOTODYNAMIC THERAPY WITH VERTEPORFIN FOR CHOROIDAL NEOVASCULARIZATION ASSOCIATED WITH RETINAL PIGMENT EPITHELIAL DETACHMENT IN AGE-RELATED MACULAR D…
2007
Abstract PURPOSE: To assess the effectiveness of photodynamic therapy (PDT) with verteporfin for choroidal neovascularization (CNV) associated with retinal pigment epithelium detachment (PED) in age-related macular degeneration. METHODS: Thirty eyes of 26 patients with CNV and PED were treated with PDT. The eyes were divided in two groups based on CNV location in relation to PED; group 1 included 13 eyes with CNV within PED, and group 2 included 17 eyes with CNV at the edge of PED. The median follow-up was 16 months. RESULTS: Patients received a mean +/- SD of 2.83 +/- 1.26 treatments (range, 1-6 treatments). In the whole cohort, the mean preoperative visual acuity changed from 20/144 (0.86…
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…
A strange pneumonia
2013
We report the case of a 62-year-old man with non-ST elevation myocardial infarction complicated by partial rupture of the antero-lateral papillary muscle in which severe mitral regurgitation with lateralized direction towards the right pulmonary veins gave unilateral pulmonary oedema, resembling an acute pneumonia.Unilateral pulmonary oedema is a rare entity, more frequently appearing as opacity of the right lung and always associated with severe mitral regurgitation. It is very important to suspect and promptly recognize unilateral pulmonary oedema because initial misdiagnosis leads to a delay in the initiation of appropriate treatment and to an increased risk of mortality.

Up‐regulation of the α‐secretase ADAM10 by retinoic acid receptors and acitretin
2009
Late-onset Alzheimer's disease is often connected with nutritional misbalance, such as enhanced cholesterol intake, deficiency in polyunsaturated fatty acids, or hypovitaminosis. The alpha-secretase ADAM10 has been found to be regulated by retinoic acid, the bioreactive metabolite of vitamin A. Here we show that retinoids induce gene expression of ADAM10 and alpha-secretase activity by nonpermissive retinoid acid receptor/retinoid X receptor (RAR/RXR) heterodimers, whereby alpha- and beta-isotypes of RAR play a major role. However, ligands of other RXR binding partners, such as the vitamin D receptor, do not stimulate alpha-secretase activity. On the basis of these findings, we examined the…
The incidence of hip, forearm, humeral, ankle, and vertebral fragility fractures in Italy: results from a 3-year multicenter study
2010
Introduction: We aimed to assess the incidence and hospitalization rate of hip and "minor" fragility fractures in the Italian population.Methods: We carried out a 3-year survey at 10 major Italian emergency departments to evaluate the hospitalization rate of hip, forearm, humeral, ankle, and vertebral fragility fractures in people 45 years or older between 2004 and 2006, both men and women. These data were compared with those recorded in the national hospitalizations database (SDO) to assess the overall incidence of fragility fractures occurring at hip and other sites, including also those events not resulting in hospital admissions.Results: We observed 29,017 fractures across 3 years, with…
The predictive role of C-reactive protein in patients with hypertension and subclinical atherosclerosis.
2009
Recent guidelines published by the joint European Society of Hypertension/European Society of Cardiology have suggested the inclusion of C-reactive protein (CRP) in the standard assessment of cardiovascular risk in hypertensive patients, but little data is available on the role of CRP in patients with carotid lesions. We studied in 472 subjects, 236 with and 236 without hypertension, gender- and age-matched, with and without early stages of atherosclerosis (e.g. those with asymptomatic intima-media thickness >0.9 mm), the influence of all the other traditional cardiovascular risk factors (e.g. older age, male gender, obesity, diabetes, smoking habit, family history of coronary artery diseas…
